Consideration of the technical field to which the invention relates.

A vacuum cleaner is an electrical device that is able to suck the outside air using a vacuum generated by an electric motor located therein, to remove dust and other foreign substances.

The basic design of such a vacuum cleaner comprises a motor located in the housing of the vacuum cleaner, designed to create a vacuum dust collector configured to collect dust and other foreign substances, and a suction nozzle located in the housing, for sucking dust and foreign substances.

When using this design, the user includes a vacuum cleaner in a state in which the suction nozzle is placed on the floor or carpet. In this case, the air and foreign matter sucked into the suction nozzle under the action of vacuum generated by the motor, and the intake air and foreign substances are moved to the filter or cyclone device located in the housing of the vacuum cleaner. Then what about the foreign substances collected in the dust box, and the air comes out from the body of the vacuum cleaner with an electric motor.

Stirrer with a brush, can be installed in the suction nozzle of the conventional vacuum cleaner. When the stirrer is set in motion, the bristles of the brush to clean off any foreign substances deposited on the surface being cleaned, removing them from the surface.

However, when human hair wound around this agitator brush, the hair of the man do not move into the vacuum cleaner housing, and remain wound around the agitator due to the rapid rotation of the agitator, and a low suction power of the vacuum machine. In accordance with this user, to his discomfort, removes hair wound manually.

In addition, when the surface being cleaned is a carpet, stretch worsen the situation of the villi. In the case where the NAP of the carpet are very long, bristle brush, located on the mixer, penetrate into the pile of the carpet, and the mixer will not be successfully spun.

Summary of the disclosure

Accordingly, the present invention relates to a vacuum cleaner and the suction nozzle for a vacuum cleaner, which essentially excludes one or more problems due to limitations and disadvantages of the technical field to which the invention relates. The purpose of this invention is to provide a vacuum cleaner and the suction nozzle for a vacuum cleaner, which can be prevented wrapping hair man long and extraneous threads around the agitator.

Another objective of the present invention is to create a vacuum and suction nozzle for a vacuum cleaner, which can clean the surface to be cleaned effectively and without overloading the motor.

To address these challenges and achieve other advantages and in accordance with the purpose of the invention implemented and widely described in this proposal suction nozzle for a vacuum cleaner includes a casing suction nozzle; an agitator is located rotatably in the casing of the suction nozzle; a support element protruding from the center of the agitator in the radial direction, while the support element is configured rotatable relative to the agitator; and a percussion element associated with the support element, to attack on the surface, when the stirrer is set in motion.

The impact element can be movable relative to the support element.

The impact element can be positioned in the longitudinal direction of the agitator, and the impact element can be rotatable relative to the reference element.

The support element may include a first elongated section that is associated with the possibility of rotation with the agitator; a second elongated section, bent, continuing from the first pull is on the site; and third elongated section that is bent and extends from the second elongated section and percussion element can be placed with maintaining the third elongated section.

The second elongated section can be from the center of the agitator in the radial direction.

The internal diameter of the impactor may be larger than the outer diameter of the third elongated section.

There are many percussive elements, annular or circular in shape, which are independently movable.

The striker may include a cavity and a penetrating hole formed in the outer circular surface of it, to create a message cavity with an external party.

The agitator may include a recess configured to limit the space for rotation of the support element.

May be there are many percussive elements, and a specified number of impactors may have brushes that are associated with their specified areas.

May provide a set of reference elements configured to secure a variety of percussive elements, respectively, and a specified number of support elements configured to secure the percussion elements, with a brush, may be less in the radial direction than the other reference elements.

The distance from the center m is chalky to one end of the brush may be identical to the distance from the center of the mixer until the striker, not with a brush.

The agitator may include a main part located rotatably in the casing of the suction nozzle, and the main part may include a side surface main parts, separated by a specified distance from each other; the Central main part located between the side surface support part and the support element connecting the side surface support part with each other, and at the same time supporting element is separated from the Central main part.

According to another object of the invention, the vacuum cleaner includes a suction nozzle according to one of claims 1-14; and the vacuum cleaner housing and connected to the suction nozzle.

According to at least one of the accomplishments during the rotation of the agitator supporting the impactor hit the surface. Dust or foreign substances up and can be removed from the surface.

In particular, when the surface to be cleaned is a carpet, with villi, foreign substances or dust that is deeply ingrained in the roots of the villi, rises hitting percussion elements and can be effectively removed.

In addition, the impactor according to the implementations may be movable against the sustained fashion axis, passing outwards in the radial direction, and not with respect to the outer circular surface of the agitator. Even when the agitator rotates at a constant speed on the surface to be cleaned can be applied blows with more force due to the centrifugal force. In accordance with these specifications cleaning can be improved.

Further, long extraneous threads, easily winded around the agitator, such as human hair, can nakativaetsa around the agitator that is located in ordinary suction nozzle, and it is necessary to perform a minor operation to remove wound filaments. However, according to the realizations of the shock element connected to rotate with the agitator, and he can turn in a direction different from the direction of rotation of the agitator. In accordance with this can be prevented by wrapping extraneous fibres such as human hair, around the agitator, and an operation to remove the wound extraneous threads of the suction nozzle according to the implementations can be excluded.

Description of specific implementations

In the following detailed description will be made reference to the figures of the accompanying drawings, which form a part of it and which for illustration is shown a specific embodiment of the invention. Specialists in the art should understand that there may be other implementation, and structural, electrical, and procedural changes may be made without deviation from the scope of the present invention. Wherever possible, the same position will be used throughout the drawings to designate the same or similar parts.

In Fig.1 shows a suction nozzle according to one implementation, suitable for vacuum and suction nozzle can be connected to the housing (not shown) of the vacuum cleaner through the suction hose 2. At the same time, the vacuum cleaner may include a motor configured to create a vacuum and a dust collector configured to collect dust and other foreign substances.

In this case a vacuum cleaner connected to the suction nozzle 1 may be not only a bed in canister vacuum cleaner type, but also a vacuum cleaner of the upright type.

Suction nozzle according to this implementation includes a casing 10, which gives the configuration is tion, defines the appearance of the nozzle, and the stirrer 20, located rotatably in the casing 10.

The mixer 20 is connected with a drive motor (30, see Fig.3) mounted in the casing 10, and it can rotate during operation of the drive motor 30.

As will be described later, the agitator 20 may be connected with a drive motor 30 directly or through an auxiliary power transmission element, and examples of such element of the power transmission includes a belt.

The agitator 20 may include a primary node (21, see Fig.3), supported rotatably right and left inner surfaces of the casing 10. Percussion element 100 connected to rotate with the agitator 20 may be located in the main node 21 for strikes on the surface during the rotation of the agitator 20.

The impactor 100 may be located on the outer circular surface of the mixer 20 in the longitudinal direction of the mixer 20 to the right and to the left, while they are spaced at a specified distance from each other.

As shown in Fig.2, the master node 21 of the mixer 20 may include a side surface support parts 22 and 23 and a Central main portion 24 that engages with the side surface of the supporting parts 22 and 23. In this case, the Central main part 24 may be cylindrical in shape.

Supporting element 150 is connected to rotate with the side surface of the supporting parts 22 and 23. In accordance with this supporting element 150 can be rotated about a shaft connected to the side surface of the supporting parts 22 and 23.

Percussion element 100 is connected to rotate with the supporting member 150, and it can move relative to the mixer 20.

Percussion element 100 can be positioned near the outer circular surface of the Central main portion 24. However, it is preferable that the shock element 100 was located at a specified distance from the outer circular surface of the Central main portion 24. The reason is that the shock element 100 may be configured to freely rotate without interference with the Central main part 24.

In addition, the shock element 100 is removed in the radial direction from the outer circular surface of the Central main portion 24. Accordingly, when the stirrer 20 is rotated, percussion element 100 is located farther from the center of rotation of the agitator 20 than the outer circular surface of the agitator 20. In other words, the shock element 100 has a larger radius than the stirrer 20, so that it can create a large centrifugal force in comparison with the centrifugal force generated by the outer circular surface of the agitator 20. In accordance with this udarn the th element 100 can hit the cleaned surface with greater force compared to the force of the agitator 20.

Meanwhile, when the stirrer 20 is rotated, the striker can be moved in the same direction of rotation as the mixer 20. However, the impact can damage the surface being cleaned and in the same time to turn on the supporting element 150 as the axis.

A unique feature of shock element 100 according to this implementation is that the direction of rotation of the impactor 100 may not match the direction of rotation of the drum element.

A shock element 100 is in a state in which it is placed on the supporting element 150 connected with the side surface of the supporting parts 22 and 23. At the same time, the internal diameter of the impactor is greater than the external diameter of the support element 150.

In accordance with this shock element 100 can be rotated relative to the support element 150.

Meanwhile, the distance between the supporting member 150 and the Central main part 24 may be greater than the thickness of the shock element 100, so that the impact element 100 can freely move between the support element 150 and the Central core part 24.

Alternatively, the inner diameter of the impactor 100 may be identical to the external diameter of the support element 150. In this case, the percussion element 100 is placed or planted with tension on the supporting element, and percussion ale is NT 100 strikes the surface being cleaned in a fixed condition without rotation relative to the support element 150.

Meanwhile, to increase the friction force relative to the surface being cleaned shock element 100 can be formed from a rubber material.

It is possible to form a set of reference elements 150 spaced at specified distances from each other on the outer circular surface of the Central main portion 24. Accordingly, the impactor 100 may be spaced at specified distances from each other on the outer circular surface of the Central main portion 24.

In accordance with this percussion elements can form multiple rows with respect to the Central main portion 24, and preferably many rows you pass to the specified distance from each other.

The impactor 100, forming one row, you can perform many rings 101. Through the ring 101, the components of the impactor 100, not connected to each other, skipped supporting element 150, so that the rings can be saved.

As shown in Fig.3, the mixer 20 is connected with a drive motor 30 located in the casing 10 of the suction nozzle.

The drive motor 30 and the mixer 20 can be connected to each other by means of the element 40 power transmission, such as a drive belt. Alternatively, the drive motor 30 and the mixer 20 can be connected to each other directly.

As mentioned above, the impactor 100 may be arranged in multiple rows, multiple rows can be spaced at specified distances from each other. The impactor 100, the components of each of the rows, can be attributed to the distance from the outer circular surface of the Central main portion 24.

As shown in Fig.4, the mixer 20 and the shock element 100 can be located near the inlet 11 and the guide holes 12 provided in the casing 10.

Dust and air can move into the body of the vacuum cleaner through the routing hole 12.

Percussion element 100 can be formed with an annular or circular shape, and each of the supporting elements 150 can be inserted into the impactor 100, forming each of the rows.

Preferably, the internal diameter of the impactor 100 was greater than the outer diameter of the support element 150. In addition, it is preferable that the thickness of the shock element 100 was less than the distance between the Central core part 24 and the supporting member 150. Accordingly, the striker can move freely on the support element 150 and supported them. When the movement of the agitator 20 percussion elements can move freely in a state of complete support of the supporting element.

Such free movement of the shock element makes possible the th attacks on the surface.

Alternatively, the internal diameter of the impactor may be identical to the external diameter of the support element 150. In this case shock element 100 may be mounted stationary on the support element 150. Even when the stirrer 20 is moving, percussion element 100 may be in a state in which it is fastened to the supporting element 150.

The supporting elements 150 may be spaced at specified distances from each other, observed by the mixer 20. When the stirrer 20 is rotated, the supporting element 150 may become detached from the outer circular surface of the agitator 20 under the action of centrifugal force generated by the rotation of the agitator 20. However, when the shock element 100 that is associated with the supporting member 150 comes into contact with the surface being cleaned, the support element 150 may temporarily be located near the outer circular surface of the agitator 20.

Similarly, the impactor 100 may be spaced at specified distances from each other, observed by the mixer 20. When the stirrer 20 is rotated, the striker can hit 100 on the surface, with the striker can hit 100 on the surface repeatedly during contacts with her.

At the same time rotating the striker can hit 100 on the surface regardless of the movement of the support element 150.

As shown n the Fig.5, supporting element 150, which is suitable for this exercise, can last from a side surface of the support portion 22 in the opposite direction.

In particular, the support element 150 includes a first elongated sections 152 associated with the side surface of the supporting parts 22 and 23, the second elongated section 154 that extends from the first elongated section, and a third elongated section 156 that extends from the second elongated section 154.

The first elongated section 152, a second elongated section 154 and the third elongated section 156 are angled from each other at predetermined angles.

The first stretches of 152 can last from a side surface of the support parts 22 and 23 are free to rotate relative to the side surface of the support parts 22 and 23. Accordingly, when the stirrer 20 is rotated, that is, rotate the side surface support parts 22 and 23, the second elongated section 154 can be deployed in a radial direction by centrifugal force.

Percussion element 100 can be supported by third elongated section 156. A large value of the mass impactor 100 and the support element 150 generates the load on the third elongated section 156, which is a percussion element 100. In other words, the center of mass is formed to fit to the third elongated section 156, and the striker is 100 is fed to the greater centrifugal force in comparison with the centrifugal force due to rotation of the agitator 20, so on the surface to be cleaned kick can be applied with greater force.

You can provide a set of reference elements 150, spaced from each other, and many supporting elements 150 may be remote from the Central main part 24. Supporting element 150 may be in the form of a rod.

The impactor 100 can be configured in multiple rows, and a row of impact elements 100 ring-type or circular type will adjoin to each other. Such shock elements located in the same row can be associated with one supporting element 150, while supporting element is inserted into them.

In this state, the side surface support part 23 provided on other parts of the Central main portion 24, is connected with percussion elements 100, and the side surface support part 23 is connected with the end of the support element 150.

In accordance with this can be prevented separation of impactors 100 from the support element 150.

In Fig.6 presents a view illustrating a variant of the impactor according to one implementation.

As shown in Fig.6, an installation hole formed at the center of percussion element for inserting the third of an ongoing plot 156, and preferably, the internal diameter of the mounting holes was greater than the outer diameter of the support element.

As the show is but in Fig.6(b), percussion element 500 may be tubular, without penetrating holes 502 formed therein. As shown in Fig.6(C), percussion element 500 may be tubular, with many penetrating holes 502 formed therein. At the same time, many penetrating holes may be formed all over the outer circular surface of the cylindrical drum item 500.

The reason for forming penetrating holes 502, is that dust arising after the strike on the surface, must be quickly separated from the cleaned surface to move.

In other words, if there was no space in which dust moves, even if you attempt to move the dust deposited on the surface being cleaned, by attacking on the surface of the shock element dust will not move and will pressoffice. However, the penetrating holes 502 formed, and the dust can be carried in the penetrating holes 502 for drawing percussion elements.

After that, the dust, stretched percussion elements 500 can be sucked through the suction when the suction in the vacuum cleaner housing to move only in the case of a vacuum cleaner.

Below with reference to drawings will be described the operation of the suction nozzle according to the implementation.

As shown in Fig.7, the vacuum soglasnoplanu include, and creating a vacuum motor (not shown) located in the housing (not shown) of the vacuum cleaner is driven. In accordance with this dust and other foreign matter lying on the surface being cleaned (C) under the suction nozzle 1 can be sucked into the suction nozzle 1 in accordance with the vacuum in the suction.

At the same time rotates the agitator 20. While it is preferable that the mixer 20 is rotated forward and the dust moved in the opposite direction relative to the suction nozzle.

In this case, the supporting element 150 and the shock element 100 can be located on the agitator 20. Supporting element 150 is movable relative to the mixer 20, and the position of the impactor 100 is continuously changing in accordance with the rotation of the agitator 20.

In other words, centrifugal force is formed, because the mixer 20 is rotated, and the support element 150 moves away from the center of the agitator 20, when the shock element 100 is not in contact with the surface being cleaned. In contrast, when the reference element 150 is pressed percussion element 100, which is in contact with the surface being cleaned, the support element 150 is deflected to the mixer.

Therefore, percussion element 100 is freely supported on the supporting member 150, and he can deviate to the outer circular surface of the agitator 20 Central is mportant force. In other words, the centrifugal force of the agitator 20 allows the shock element 100 and the support element 150 to perform individual movement.

When the stirrer 20 is continuously moved in this state, the striker continuously hits on the surface (C), and in accordance with these foreign substances can be separated from the surface being cleaned (With).

In particular, the impact element 100 hits on the surface (S) in a state of rotation, while it is farther than the outer circular surface of the agitator 20. So that foreign matter can be easier separated from the surface being cleaned (With).

When the surface to be cleaned (C) is a carpet having a pile, percussion element 100 can remove dust or foreign substances from the deep cut near the roots of the pile. Suspended dust or foreign matter can be sucked into the suction nozzle 1 to move into the body of the vacuum cleaner.

If the shock element 100 still be associated with a stirrer 20, long extraneous threads, such as human hair, can nakativaetsa in circles impactor 100 and the mixer 20.

However, the supporting element 150 is connected to rotate with the agitator 20, and the shock element 100 is connected to rotate with the supporting member 150, so long extraneous threads, such as human hair, can't aratiatia around the agitator 20, and can be prevented by wrapping them around the outer circular surface of the impactor 100.

If the internal diameter of the impactor 100 is identical to the external diameter of the support element 150, percussion element cannot be rotated relative to the reference element. Accordingly, when the stirrer 20 is rotated, the supporting element 150 may be movable relative to the mixer 20, and the shock element 100 may be movable relative to the mixer along with the supporting member 150.

In Fig.8 shows a perspective view of the impactor and the mixer according to another implementation. In Fig.9 presents a cross-section of part of Fig.8. Below with reference to Fig.8 and 9 will be described in the second implementation.

The recess 26 may be formed in the Central main portion 24 of the mixer 20 for more space, in which the supporting elements 150 are moved or rotated. In other words, the supporting elements 150 can be rotated within the recess 26.

The recess 26 may be continuously cut in the longitudinal direction of the outer circular surface of the Central main portion 24. The notches 26 may be executed in the external circular surface spaced at specified distances from each other in the direction of rotation of the Central main portion 24.

Meanwhile, the area of the recess 26, which is situated od the n end of the second elongated section 154, can be cut deeper toward the Central main portion 24 than another area. In other words, the cross section of the recess 26 may be approximately arcuate.

Preferably, the support element 150, in particular the first elongated section 152 (the position of the first elongated section 152 is the same as the position of one end of the second elongated section 154), was fixed near the notches 26. Accordingly, even if the supporting element 150 is rotated, the rotation range of the support element 150 may be restricted by the shape of the recess 26, and the work of the support element is not interrupted.

Percussion element 600 according to this implementation may include a brush 50 attached to the given section. The brush 50 may be acting like a bristle. Since the shock element 600 is able to rotate relative to the support element 150, the shock element 600 is rotated and the brush 50 of scraping the surface being cleaned with the cleaning.

In other words, when the stirrer 20 is rotated, the supporting elements 150 move away from the center of the agitator 20 in the radial direction. In addition, the brush 50 may have given a lot, and she pulls away from the mixer 20.

Meanwhile, when the shock element 600 is in contact with the surface being cleaned, the brush 50 is in contact with the surface being cleaned. The brush 50 is bent and p is imaeda, and the pressure is scattered, so that impurities can be effectively separated by strong contact with the surface being cleaned.

In Fig.10 presents a perspective view with the local section, illustrating a variant of the second implementation. In Fig.11 presents a cross-section of part of Fig.10. With reference to Fig.10 and 11 will be described variant of the second implementation.

According to a variant of the second implementation of the specified number of percussion elements has a different shape compared to other percussive elements that differ from those shown in Fig.8 and 9.

In other words, shared the impactor with the brush 50, and percussion elements 600, no brushes 50. The impactor with the brush 50, the identical impact elements mentioned when referring to Fig.8 and 9. Percussion elements 500, no brushes, identical shock elements according to the first implementation. Accordingly, the various elements will be described in this implementation.

The supporting elements 150 that are used in percussion elements 500, no brushes, different from the supporting elements 150 that are used in percussion elements 600, with brushes on the length of the second elongated section 154.

In other words, the support element 150 that is configured to secure the shock element 600 having the brush 50, is at a smaller distance R is dialnum direction from the mixer 20, what other supporting elements. In particular, the distance (R) from the center of the agitator 20 to one end of the brush 50 may be identical to the distance (R) from the center of the mixer 20 to the percussive element 500, not with a brush.

The centrifugal force created during rotation of the agitator 20. When the specified number of percussion elements differs from other percussive elements, so that the center of the total mass, which has a stirrer 20, is not located in the center of the agitator 20. Accordingly, when the stirrer 20 is rotated, the center of mass is continuously changing and you may shake mixer 20.

To reduce the shock that is generated during the rotation, extended length (R) of the percussion elements 500 and 600 from the center of the agitator 20 is made equal. When the extended length of the percussion elements are limited in the same way, each component can be in the same range of lengths, and can be prevented from deviating from the center of the agitator 20 center of mass applied to the mixer 20.

In the variant of the second implementation of the impactor with the brush 50, and percussion elements 600, no brushes are used interchangeably. In accordance with this, the bumps on the surface can be applied in different ways, and the cleaning efficiency can be enhanced. After the impactor 600 with brushes 50, strike blows on the surface, udarn the e elements 500, no brushes, one after another strike on the surface.

Meanwhile, according to the second implementation using percussion elements 600, with the brush 50 can scrape the surface to be cleaned. In particular, even if the cleaning implement with the use of the percussion elements 600, with brushes 50, long extraneous threads, such as human hair, can not in sufficient number to attach to mixer 20, so that it would be difficult to pull from the percussion elements 600. The fact that the supporting element 150 that supports the percussion element 600 is not enshrined in the state in which the position of the support element 150 is fixed. When the stirrer is rotated, the supporting elements 150 continuously perform various motions, such as rotation. In accordance with this long extraneous threads, such as human hair, suscribase brushes 50, while the position of foreign substances may change over time due to movement of the percussion elements 600. When this foreign substance can be absorbed into the vacuum cleaner through the suction force.

For specialists in the art should be obvious that various modifications and variations of the present invention may be made without departure from the essence or scope of the invention.
