Detailed description of the invention

Next will be described in detail with reference to the accompanying drawings typical implementations of the present invention to implement the above tasks.

As shown in Fig.1, suction nozzle, indicated by the reference number 1, according to a variant implementation of the present invention can be applied to the vacuum cleaner and can be connected with jus the m body (not shown) of the vacuum cleaner suction hose 2. In this case, the vacuum cleaner may include a motor to create a vacuum and the capacity for accumulation of dust, which is collected dust and other debris.

Here the vacuum cleaner is attached to the suction nozzle 1 may be a vacuum cleaner filter type or upright vacuum cleaner.

Suction nozzle 1 according to an implementation variant of the present invention includes a housing 10 that defines the appearance of the suction nozzle 1 and the agitator 20, mounted rotatably in the casing 10.

The agitator 20 may be connected with a drive motor (30, see Fig.3) mounted in the casing 10 so as to rotate due to the drive from the drive motor 30.

Although this will be described later, the agitator 20 may be directly connected with a drive motor 30, or may be directly connected via a single transmitting power element (40, see Fig.3), such as a belt, and so on

The agitator 20 includes a body (21, see Fig.3), which is supported rotatably inside left surface and a right internal surface of the casing 10. Many impactors 100 are connected for rotation with the agitator 20, in particular with the body 21. The impactor 100 may come into contact with the purified plane during rotation of the agitator.

The impactor 100 may be placed longitudinally in the direction of the agitator 20 (in the drawing in the direction of the left and right) and can be located at a distance from each other along the outer circular surface of the agitator 20.

As shown in Fig.3, the body 21 of the agitator 20 may include a lateral support parts 22 and 23 and the Central portion 24 of the body connected with the two lateral support parts 22 and 23. The Central part 24 of the body may have a cylindrical shape.

Although the impactor 110 can be placed close to the outer circular surface of the Central portion 24 of the body, it is desirable that the impactor were separated from the outer circular surface of the Central portion 24 of the body a certain distance.

The above-described configuration serves to prevent mutual influence between the impact elements 100 and the Central part 24 of the body.

During rotation of the agitator 20 the impactor 100 may be rotated by receiving the rotational force from the agitator 20 in the same direction as the direction of rotation of the agitator 20. However, it will be clear that the impactor 100 may rotate some to come into contact with the purified plane without the help of the agitator 20.

The impactor 100 have a sign, namely, that the impactor 100 may move in a circle in a given direction, but the direction of rotation of each drum element 100 may be different from the direction of circular motion.

For this purpose, each of the impactors 100 are inserted into the supporting element 150, which is connected with the two side parts 22, 2 body, to cover support element 150. In this case, the internal diameter of the impactor 100 is greater than the outer diameter of the support element 150.

Accordingly, the shock element 100 rotates freely relative to the support element 150.

The distance between the supporting member 150 and the Central part 24 of the body may be greater than the thickness of the shock element 100, which may ensure that the impact element 100 can rotate freely between the support element 150 and the Central part 24 of the body.

Many supporting elements 150 are separated from each other in relation to the outer circular direction of the Central part 24 of the body, and percussion elements 100 are separated from each other in relation to the outer circular direction of the Central part 24 of the body so as to correspond to the respective supporting elements 150.

With this arrangement, the impactor 100 may be located in multiple rows around the Central part 24 of the body, and many rows can be spaced from each other.

Percussion element 100 constituting one row can be made from a variety of rings 101. In this variant implementation of the rings 101, forming a shock element 100, not connected to each other and inserted into the support element 150 so as to maintain its original position.

As shown in Fig.3, the agitator 20 is connected with a drive m is a torus 30, which is installed inside the casing 10 of the suction nozzle 1.

The drive motor 30 and the agitator 20 may be interconnected via the transmitting power of the element 40, such as a drive belt, or they can be directly connected to each other without space between them transmitting power element 40.

Percussion element 100 is connected for rotation between the side supporting parts 22 and 23, which are respectively located at both ends of the Central part 24 of the body.

As described above, the impactor 100 are placed in multiple rows, separated from each other. The impactor 100 of the respective rows can be placed around the circular surface of the Central portion 24 of the body.

As shown in Fig.4, the agitator 20 and the shock element 100 may be adjacent to a suction port 11 and the guide port 12, is made on the casing 10.

Guide port is used to direct the movement of dust and air in the main body of the vacuum cleaner.

The impactor 100 consist of rings or loops and mounted on the respective supporting elements 150.

It is desirable that the internal diameter of the impactor 100 was much greater than the outer diameter of the support element 150 and the wall thickness of the shock element 100 was less than the distance between the Central part 24 of the bodies and the supporting member 150.

Accordingly, the shock element 100 can be easily worn and can be supported by the supporting member 150, and can move freely, being mounted on the support element 150, at that time, when moving the agitator.

Due to the above-described free configuration, the impactor 100 may effectively come into contact with the cleaned surface.

On the basis of the agitator 20 percussion elements 100 are separated from each other by a certain distance. Thus, during rotation of the agitator 20 the impactor 100 may repeatedly come into contact with the cleaned surface.

As shown in Fig.5 with respect to the first embodiments of the present invention, the support element 150 may be extended element, placed between the two lateral support parts 22 and 23.

Many supporting elements 150 are placed so as to be spaced from each other. Many supporting elements 150 are located at a distance from the Central part 24 of the body. The supporting elements 150 can be in the form of rods.

Percussion elements 100, which are arranged in many rows, formed by placing multiple rings or loops next to each other, and many rings or loops of each percussion element 100 are wearing and held one support element 150.

After training shock element 100 is mounted on the reference ale is NT 150 so as described above, one end of the support element 150 is connected with the side supporting part 23, which is pre-attached to one end of the Central part 24 of the body.

When the above-described method of Assembly, it may be possible to prevent unintentional separation of the shock element 100 from the support element 150.

In Fig.6 shows a second embodiment of the present invention.

In the second variant of realization, in contrast to the above-described first embodiments in which the impact element 100 is formed of a separate thin rings or loops, percussion element 200 can be formed by a combination of several thin connecting links in the form of a ring or loop.

Many connecting links form a separate series of percussive element 200, and a variety of percussion elements 200 are at a distance from the circular surface of the body 25 of the agitator 20. Similarly, a variety of percussive elements 200 are arranged at a distance from each other.

The body 25 of the agitator 20 has grooves 26, which form the space required for the movement or rotation of the percussion elements 200.

The grooves 26 may take the form of a continuous straight grooves cut in the outer circular surface of the body 25. Preferably, the grooves 26 are located at a distance from each other in the direction of the AI rotation body 25.

Each of the impact elements 200 is supported by the supporting member 250.

Unlike the above-described first variant implementation of the support element 250 includes a support holder 251, made on the outer circular surface of the body 25 of the agitator 20, and the shaft 252 is inserted into the support holder 251.

The support holder 251 has a mounting recess a, which can be inserted into the shaft 252.

Accordingly, if the shaft 252 is inserted into the installation recess a support holder 251 in a situation in which the impact element 200 is mounted on shaft 252, the shaft 252 is attached to the body 25.

In this case, it is desirable that the width of the entrance into the installation recess a was slightly less than the outer diameter of the supporting shaft 252 so that the shaft 252 is inserted with interference in the installation recess a without danger of separation.

According to the options the implementation of a couple of supporting holders can be placed on both ends of the outer circular surface of the body 25, or one extended support holder 251 can be placed on the outer circular surface of the body 25 along the line of its length.

At the same time, it is desirable that the part of the holder 251 was installed in the groove 26 so as to guarantee the presence of shock element 200 in the groove 26.

In Fig.7 showing the n third embodiment of the present invention.

As shown in Fig.7, according to the third variant of realization of the shock element 500 takes the form of a hollow tube, having many through holes 501, distributed over its circumference.

Many heating elements 500 can be placed in multiple rows, and each of the percussion elements 500 can be formed with a set of pipes or pipe.

Here the shock element 500 may take the form of a circular tube, but the possible impact elements of pipes of various other forms.

The body 25 of the agitator 20 is placed on the outer circular surface with grooves 26, which form a space for movement or rotation of the percussion elements 500.

It is desirable that the grooves 26 were straight grooves running in the longitudinal direction of the body 25 so as to correspond to the layout direction of the percussion elements 500.

Each percussion element 500 rests rotatably on a support element 350. The support element 350 includes a bearing holder 351 performed on the outer circular surface of the body 25 of the agitator 20, and the support shaft 352 inserted from the side into the support holder 351.

Percussion element 500 is inserted and supported by the support shaft 352, and in turn the support shaft 352 is inserted from the side into the support holder 351, which prevents unintentional separation drum item 500. In this case, porny holder 351 limits inside the channel 353. Accordingly, the support shaft 352 can be closely coupled to the reference holder 351 so that the supporting holder 351 surrounds the outer circular surface of the support shaft 352.

Percussion element 500 is freely mounted on the shaft 352 and can rotate freely relative to the support shaft 352.

In the present embodiment, the implementation may provide a set of reference holders 351, placed on both ends of the outer circular surface of the body 25, and the bearing holders 351 located in the grooves 26. Thus, the support shaft 352 can be supported by the supporting holders 351 so as to linearly extend in the longitudinal direction of the body 25.

As shown in Fig.8(a), in alternative implementations shock element 500 may, at the centre to restrict the installation hole 501, in which is inserted the shaft 352. It is desirable that the diameter mounting holes 501 was significantly greater than the diameter of the support shaft 352.

The difference between the second embodiment of the implementation shown in Fig.6, and the third alternative implementation shown in Fig.7 is the method of installation of a supporting shaft 252 or 352 in the support holder 251 or 351.

That is, the shaft 252 in the second variant of realization is inserted through the entrance of the installation recess a support holder 251, while the support shaft 352 in the third embodiment, p is the realization of insert side in the bearing holder 351 so, to skip through hole 353.

As shown in Fig.8(b), in another alternative implementation of the percussion element 500 may take the form of a pipe having no through holes 502. As shown in Fig.8(C), in another alternative implementation of the percussion element 500 may take the form of a pipe having many through holes 502.

The use of through-hole 502 is used to promote rapid separation from the surface plane of dust released during the time when the shock element 500 is in contact with the cleaned surface.

This means that even in the presence of dust on the surface plane, which is forced to separate from the plane at the time when the shock element 500 is in contact with the plane, the dust can pressoffice on the plane in case of lack of space to move dust. Thus, the through holes 520 can provide the space to move dust, thus allowing dust to enter the inside of drum item 500.

After receipt of the dust drum item 500 dust can be sucked under the influence of vacuum in the main body and, thus, to move in the main body.

Next will be described the action of the embodiments of the present invention with reference to the accompanying drawings. Here proillyustrirovannaya generally applicable to variants of realization of the first to the third.

As shown in Fig.9, in case that turns on the vacuum cleaner according to a variant implementation of the present invention, the vacuum actuator (not shown) housed in the main body (not shown) is actuated in order to ensure the absorption under the influence of vacuum dust and other debris that is present on a plane (hereinafter referred to as the cleaned plane) under the suction nozzle.

During operation, the suction nozzle 1, the agitator 20 is rotated. In this case, it is desirable that the agitator 20 is rotated forward to move the dust backwards with respect to the suction nozzle 1.

In this case, the agitator 20 is supplied shock elements 100. The position of each impactor 100 is continuously changed according to the rotation of the agitator 20.

It is noted that the shock element 100 freely put on and supported by the supporting member 150 and is, therefore, a tendency to deviation in the radial outer direction relative to the agitator 20 under the influence of centrifugal force.

Thus, the shock element 100 may have more to act radially outward than the outer circular surface of the agitator 20.

In this state, if the agitator 20 is continuously rotated, the impactor 100 repeatedly come into contact with the purified plane, thus removing th is PR ejected from the plane C.

In particular, if the purified plane is carpeted pile N, there is a possibility of separating dust or debris, deep in a pile of N, and to getting separated dust or debris into the suction nozzle 1 and then move into the main body under the influence of vacuum.

If the agitator 20 is rotated counterclockwise, as shown in the drawing, the position of the individual impactor 100 is changed in a counterclockwise direction. However, each percussion element 100 can rotate regardless of the direction of rotation of the agitator 20, or may rotate in the direction opposite to the direction of rotation of the agitator 20.

If the shock element 100 is attached to the stirring shaft 20 so as not to be able to rotate relative to the agitator 20, there is a danger of winding long debris, such as hair, percussion element 100 and the agitator 20.

However, since the impactor 100 is connected to the stirring shaft 20 for rotation, it may be possible to prevent long winding debris, such as hair on the agitator 20 and on the outer circular surface of the impactors 100.

At the same time, the shock element 100, which is adapted to come into contact with the purified plane, can rotate in the direction FR is opposite to the direction of rotation of the agitator 20. As shown in Fig.9, at a time when the agitator 20 is rotated counterclockwise, clockwise direction, the force may be applied to a percussion element 100 due to friction between the impact element 100 and cleaned the plane at the time when the shock element 100 is in contact with the purified plane C. Accordingly, the shock element 100, which comes in contact with the purified plane, can rotate in the direction of rotation regardless of the agitator 20 or in the direction opposite to the direction of rotation of the agitator 20.

Next, another embodiment of the present invention will be described with reference to Fig.10-18. For comparison, in contrast to the above-described embodiments of the present invention, according to a second described embodiment of implementation in addition to the percussion element 100 of the agitator 20 set the brush 50. Accordingly, the description of parts similar to those described for the embodiments above will be omitted here, and the following description focuses only on the differences.

In particular, compared with the corresponding variants of realization according to Fig.5, 6 and 7 corresponding to such embodiments, which will be described later with reference to Fig.14, 18 and 19, have the distinction relating to the installation of the brush 50 using the same technology described above. Boathouses will be omitted in the detailed description of Fig.14, 15 and 16.

Suction nozzle 1 according to a second described embodiment, the implement includes a casing 10, which describes the appearance of the suction nozzle 1 and the agitator 20, is placed rotatably in the casing 10.

In particular, the agitator 20 includes a brush 50, which is attached to the agitator 20. The brush 50 is radially from the center of the agitator 20 to perform the cleanup, such as scraping, clean plane C.

The brush 50 may be installed on the installation ledge (28, see Fig.13) radially away from a Central part 24 of the body. In this case, the brush 50 is attached to the installation ledge 28 and rotates at the same rotation of the agitator 20, differing from the impactor 100.

As shown in Fig.13, percussion elements 100 are placed in multiple rows and multiple layers are located at a distance from each other. The impactor 100 of the respective rows can be placed on the outer circular surface of the Central portion 24 of the body.

Many of the brushes 50 may be placed in multiple rows arranged at a distance from each other. Similarly, the brush 50 of the respective rows can be placed on the outer circular surface of the Central portion 24 of the body.

In particular, the impactor 100 and the brush 50 may be alternately placed on the outer circular surface porosities and in particular, on the outer circular surface of the Central portion 24 of the body. There are two brushes 50 may be placed respectively on both sides of each drum element 100, and similarly two impactor 100 may be placed respectively on both sides of the brush 50.

The agitator 20, the impactor 100 and the brush 50 may be placed next to the suction port 11 and the guide port 12, is made in the casing 10.

Because the brushes 50 are placed respectively between multiple percussion elements 100, during rotation of the agitator 20 percussion elements 100 and brushes 50 are alternately in contact with the purified plane for cleaning.

Next will be described the operation again described embodiments of the present invention with reference to the accompanying drawings. Here is illustrated the work, in General, refers to the first or third options for the implementation of the second described embodiments.

As shown in Fig.17, when turning on the vacuum cleaner according to the present invention, the vacuum actuator (not shown) housed in the main body (not shown) is actuated in order to ensure the absorption under the influence of vacuum dust and other debris present on the surface plane under suction nozzle.

During operation, the suction is that the nozzle 1, the agitator 20 is rotated. In this case, it is desirable that the agitator 20 is rotated forward so as to promote the dust backwards with respect to the suction nozzle 1.

In this case, the agitator 20 is supplied shock elements 100 and brushes 50. The position of each drum element 100 and the position of each brush element 50 is continuously changed according to the rotation of the agitator 20.

It is noted that the brush 50 is rotated as the agitator 20, while the percussion element 100 freely put on and supported by the supporting member 150 and, thus, tends to radial deviation in the outer direction of the agitator 20 under the influence of centrifugal force.

Thus, the impactor 100 can largely extend to the outside than the outer circular surface of the agitator 20.

In this condition, if the agitator 20 is continuously rotated, the impactor 100 and the brush 50 repeatedly come into contact with the purified plane, thus removing debris from the surface plane C.

In particular, if cleared by plane is the carpet pile is N, it may be possible to separate the dust or debris, deep in a pile of N, and to allow the separated dust or debris to enter into the suction nozzle 1 and then move into the main body under the influence of vacuum.

If the agitator 20 is rotated counter hours the arrows, as shown in the drawing, the position of the individual impactor 100 is changed in a counterclockwise direction. However, each percussion element 100 can rotate regardless of the direction of rotation of the agitator 20, or may rotate in the direction opposite to the direction of rotation of the agitator 20.

During rotation of the agitator 20 brushes 50 also come into contact with the purified plane S. Thus, if long debris, such as hair, is captured by the brushes 50, there is a danger of winding long debris, such as hair, brush 50.

However, since the impactor 100 are connected for rotation with the agitator 20 in positions close to the respective brushes 50, compared with a case in which the agitator 20 are placed consecutively only brushes 50, there is less danger that debris, such as hair, is completely wound on the brush 50. For example, if the agitator 20 is placed only brush 50 without impactors 100, long waste, such as hair, can gather around consistently placed the brush 50 and may be difficult to separate the debris from the brushes 50. This is because many of the brushes 50 may cause twisting of the long waste such as hair, tangled in them, which can greatly increase the strength of the accession garbage

However, in this implementation variant, because the impactor 100 is connected for rotation with the agitator 20, it may be possible to prevent long winding debris, such as hair on the agitator 20, as well as on the outer circular surface of the impactors 100.

At the same time, under this implementation variant, the impactor 100 and the brush 50 alternately in different ways come into contact with the purified plane, which can improve the cleaning performance due to the use of different types of contact. That is, since the brush 50 and the impactor 100 may attach different contact force to the surface plane, even if the debris remains on the surface plane after the impactor 100 come into contact with the purified plane, brush 50, which then come into contact with the purified plane, can serve to separate the debris from the surface plane C.

In Fig.18 shows a view illustrating an alternative implementation of the present invention. Description of alternative embodiments will follow with reference to Fig.18.

Unlike the above-described embodiments, according to alternative implementations of the present invention in a configuration in which one of the brush 50 is placed between the neighbour by them from among the impactors 100, one striking element 100 is placed closer to the brush 50, other than the striker 100, and in particular, preferably, on the basis of the direction of rotation of the agitator 20 one impact element 100, which is placed behind the brush 50, was placed closer to the brush 50, other percussion element 100, which is located in front of the brush 50. For example, assuming that one impact element 100, which is located in front of the brush 50 in the direction of rotation of the agitator 20 is separated from the brush 50 a distance L2, and the other striking element 100, which is located behind the brush 50 in the direction of rotation of the agitator 20 is separated from the brush 50 a distance L1, and L1 is less than L2.

During rotation of the agitator 20, the time required when the brush 50 first comes in contact with the purified plane and then shock element 100 is in contact with the purified plane, is less than the time required when the striker 100 first comes in contact with the purified plane and then brush 50 is in contact with the purified plane C.

Although the shock element 100 serves for entering into contact with the purified plane, percussion element 100 can also serve to prevent capture long debris, such as hair, brush 50, located before the shock element 100 in the direction of rotation of the agitator 20, i.e. the one which is included in account the t ejected from the plane before what a shock element 100 during rotation of the agitator 20, from his capture following the brush 50.

When the brush 50, which comes in contact with long debris such as hair, continuously rotates the striker 100 behind the brush 50 freely rotates in the direction of rotation of the agitator 20 and, therefore, may come into contact with long debris such as hair, tangled in the brush 50. In this case, the rotation of the impactor 100 may cause shaking off the debris caught on the brush 50, thus allowing the separation of debris from the brush 50. At the same time, because the absorption of waste occurs during rotation of the agitator 20, long waste, such as hair, can be sucked into the suction hose.

In case the brushes 50 and impactor 100, which are located next to each other, percussion element 100 can exert more force to the long debris, such as hair, captured by the brush 50, which can prevent the capture long debris brush 50.

If the brush 50 is captured relatively short garbage, and the shock element 100 is located at a certain distance from the brush 50, percussion element 100 may not come into contact with the brush 50 and cannot, therefore, make an effort to debris captured by the brush 50. Thus, it is desirable that the shock element 100 are located close to the brush 50.

At the same time, the real garbage, such as hair, captured by the brush 50 rotates in the direction opposite to the direction of rotation of the agitator 20, being wound on the agitator 20. Accordingly, by placing the shock element 100, which is located behind the brush 50 in the direction of rotation of the agitator 20, closer to the brush 50, other percussion element 100, which is located in front of the brush 50 in the direction of rotation of the agitator 20, it is possible to sufficiently prevent a tight wrap around the brush 50 long debris, such as hair.

As is clear from the above description, in the vacuum cleaner according to the present invention during rotation of the agitator separate percussion element is used for removal of dust or debris from the surface plane by entering into a close contact with the purified plane that can provide effective removal of dust or debris from the surface plane.

In particular, if the plane is cleaned carpet pile, there is the ability to effectively remove dust or debris, deep in the pile, when the striker is in contact with the carpet pile to separate the dust or debris.

When there is debris such as hair, which can gather around the agitator, it requires an additional process to remove debris captured by the bristles of the agitator.

However, with the according to the present invention, since the shock element connected for rotation with the agitator and rotating in the direction opposite to the direction of rotation of the agitator, it is possible to prevent the winding of debris, such as hair, percussion element. Respectively can be omitted, the process of removing debris from the shock element.

According to the present invention percussion elements and brushes alternately placed on the agitator, resulting in a solution that improved cleaning, because the brushes scratch the cleaned surface and percussion elements continuously come into contact with the cleaned surface.

In addition, in the premises of the percussive element close to the brush even if the hair is captured by the brush, a freely rotating drum element can serve to separate the hair from the brush.

Specialists in this field of technology should be intuitive ability to make various modifications and changes in the present invention without deviating from the substance or scope of the invention.
