Figure 1 represents a perspective view of the vacuum cleaner of the upright type, in accordance with the embodiment of the present invention.

As shown in figure 1, a vacuum cleaner of the upright type contains the node 100 suction brush for sucking air containing foreign objects such as dust and dirt, when moving on the floor, the main body 200 in which such elements for generating suction force, as the motor and the fan set to intake air, and an operating device 210 installed in the upper part of the main body 200 so that the user could take on the working device 210 during use.

Below will be described in more detail each element of the vacuum cleaner.

The node 100 of the suction brush, which is designed to suction air, contains the top cover 110 of the brush and the bottom plate 120 of the brush, which form the upper and lower outer side of the node 100 of the suction brush, respectively. On the bottom surface of the bottom cover 120 of the brush is formed a suction hole (not shown) as a main suction opening for sucking the outside air. In addition, the node 100 of the suction brush contains wheel 220 on both sides for easy movement of the vacuum cleaner.

The main body 200 is designed to rotate back within a specified angular range relative to the host 100 of the suction brush. To regulate the rotation of the main body 200 on the upper rear end portion of the node 100 of the suction brush is provided a swing arm 130. Therefore, when the user presses his foot on the rotary lever 130 and pulls the main body 200 back, using the working device 210, the main body 200 leans back. Therefore, the user can adjust the tilt angle of the main body 200 in accordance with his/her growth.

The fastening element 230 to the wires formed in the rear part of the main body 200. Preferably a pair of fasteners 230 for the wire can be formed SIMM is techno in the rear part of the main body 200 in the upper and lower positions. Electric wire 240 can be conveniently wound on fasteners 230 for the wire.

In the main body 200 has a motor (not shown) for generating a suction force for sucking external air and foreign objects through the node 100 of the suction brush. Flexible suction hose 250 is provided in the Central part of the main body 200 for the direction of foreign objects contained in the air sucked through the node 100 of the suction brush in the dust-collecting device 300.

The main body 200 is provided with a connecting handle 260 on the front surface to detach the dust collection device 300 from the main body 200. Connecting the handle 260 helps to keep dust-collecting device 300. Thus, the dust-collecting device 300 is not detachable from the main body 200, if not to make manipulative steps with handle 260.

Under connection handle 260 is provided for the installation part 270, recessed in the main body 200. The installation portion 270 has a shape corresponding to the outer part of the dust collection device 300 for installation with dust removal device 300.

Lamp (L) is installed under the installation part 270 that can easily be cleaned dark places, such as the angle and place under the table by the lamp (L).

In a is m it is possible to understand the construction and operation of the vacuum cleaner according to the above description. Below will be described the construction and operation of dust collection device 300. In accordance with the present invention, the dust-collecting device 300 for collecting foreign objects out of the air differs in that the collected foreign objects are compacted to increase the density of the collected foreign objects.

Figure 2 is a perspective view from the spatially separated parts of dust device of a vacuum cleaner in accordance with the present invention.

As shown in figure 2, the dust-collecting device 300 is installed with the possibility of removal in the installation part 270 for filtering foreign objects contained in air passing through the node 100 of the suction brush. In the dust collection device 300 can be used cyclone element, a filter, or a combination of cyclone and filter.

Usually dust-collecting device 300 has a cylindrical shape and contains the dust collection container 310, in which the collected foreign objects, the upper and lower cover 320 and 330, which are made with the possibility of removal in the upper part and the lower part of the dust tank 310 to cover the upper part and lower part, and a porous filter 350 installed with the possibility of removal on the lower part of the lower cap 330 to filter particles from the air entering the dust collection container 310.

The upper cover 320 has a round you is uskee hole 322, obtained by perforating the Central part of the upper cover 320. Through the outlet 322 is released the air after filtering foreign objects from the air. Front outlet 322 is connecting the groove with a predetermined depth. In the connecting groove 324 is installed connecting the handle 260 to prevent detaching the dust collection device 300 from the main body.

The upper cover 320 further comprises a first hook (323 see figure 4), which acts downward with a given curvature. One end of the elastic element (E) engages the first hook 323 so that the elastic element (E) can be installed in place without disconnecting.

Dust collection container 310 is formed with suction guiding element 312 on the outer surface. One end of the suction guide element 312 protrudes from the outer surface to a predetermined length for directing air into the dust collection container 310. Suction guide element 312 is designed so that air can rotate in dust capacity 310 tangent to the inner wall of the dust collection vessel 310. With this purpose, the suction guide element 312 protrudes from the outer surface of the dust tank 310 at an angle.

Handle 314 with parts being at right angle, is from the outer surface of the dust collection e to the bone at a location opposite the suction guide element 312, so the user could easily take the dust collection device by means of the handle 314 when removing the dust collection device 300 from the main body 200. In the open upper part of the handle 314 is installed presser element 380. For this purpose, a clamping element 380 has an outer diameter corresponding to the inner diameter of the open top of the handle 314. The presser element 380, located in the handle 314 is used when the pressure on the rod 370 down.

The presser element 380 contains the installation flange (382 see figure 3), protruding downward from the upper end to a predetermined length. Mounting flange 382 corresponds to the open part of the handle 314 so that the mounting flange 382 may fit snugly around the open top of the handle 314 when installing the clamping element 380 in the handle 314. Therefore, it is difficult to detach the presser element 380 from the handle 314.

Between dust capacity 310 and the upper cover 320 is an elastic rubber seal (S) to ensure an airtight seal between the dust container 310 and the upper cover 320. Preferably the seal (S) has a shape corresponding to the shape of the upper end part of the dust container 310 to ensure that the seal (S) could be firmly established, when the upper cover 320 covers the upper end portion of the dust collection vessel 310.

The lower cap 330, which provided the Rena in the lower part of the dust tank 310, contains the hinge 332 on top for turning and opening the button 340, opposite hinge 332 to regulate the opening and closing of the lower cap 330. Therefore, when the opening button 340 is released, the lower cap 330 can be rotated downward around the hinge 332 to open the dust container 310.

In dust capacity 310 installed paleobotany element (see (P) in figure 3). When the pressure paleobotany element (P) is moved down to seal the particles collected in the dust collection vessel 310. On paleopathology element (P) can be clicked using the clamping element 380.

Figure 3 depicts a view in section along line I-I' in figure 1, and figure 4 depicts a view in enlarged scale of the area "A" in figure 3. Next will be described the construction paleopathology element (P) with reference to figure 2, 3 and 4.

Paleobotany element (P) contains the separating plate 360 button under the filter 350, to separate the inner space of the dust collection capacity on the upper and lower space, the rod 370, connected with the partition plate 360 and are able to move up and down in the filter 350 to the direction of movement of the dividing plate 360, the elastic element (E), located around the rod 370 to provide restorative force when moving the rod nes, and the presser element 380.

In detail, the separator plate 360 is connected with the lower part of the rod 370 and divides the inner space of the dust collection capacity 310 on the upper and lower spaces. Separating plate 360 has a round shape with an outside diameter corresponding to the inner diameter dust capacity 310. Therefore, the separator plate 360 may prevent backward movement of foreign objects passing through holes 362 for the passage of foreign objects formed on the circumference of the separation plate 360. The upper space dust capacity 310, separated by a dividing plate 360, is used as a partition for separating foreign objects in which foreign objects Teleuts from air using a vortex air flow, and the lower space of the dust collection vessel 310, separated by a dividing plate 360, is used as a section for collecting foreign objects in which they are going.

Separating plate 360 includes a receiving flange 364 rod, formed on the upper surface with the given height. Receiving flange 364 rod has an inner diameter corresponding to the outside diameter of the rod 370, so that when the rod 370 is installed in the receiving flange 364 rod, removing the dividing plate 360 from the rod 30 is prevented. Rod 370 can be tightly fitted into the receiving flange 364 of the rod to prevent disconnection. Also, how durable compounds such as the method of bonding may be used for connecting rod 370 and the separation plate 360.

Palermocatatonic flange 366 is around receiving flange 364 rod. Palermocatatonic flange 366 is located at a specified distance from the receiving flange 364 of the rod and has an internal diameter corresponding to the outer diameter of the lower end portion of the filter 350. The inner surface Pueblonuevo flange 366 forms a contact with the outer surface of the filter 350 to prevent the ingress of foreign objects through the gap under the filter 350.

Rod 370 has a cylindrical shape with an open upper part and a length corresponding to the length of the filter 350. Because the lower end of the rod 370 is tightly fitted into the receiving flange 364 of the rod, the rod 370 and the partition plate 360 can be moved in upper and lower directions. Therefore, foreign objects collected in the lower part of the dust tank 310 may be sealed by a dividing plate 360 when moving rod 370 down. When sealing the collected foreign objects become dense and tangled.

Rod 370 includes a support flange 372, protruding upward along the inner is th surface of the upper end portion. The mounting flange 372 forms a contact with the clamping element 380 when pushing down the rod by means of the clamping element 380. For this purpose, it is preferable that the mounting flange 372 had an inner diameter less than the outer diameter of the lower end portion of the clamping element 380. When the lower end part of the clamping element 380 clicks on the mounting flange 372 down the entire rod 370 can move down.

Rod 370 further comprises a second hook 373 formed on the outer surface with a given curvature. The form of the second hook 373 is similar to the form of the first hook 323 formed on the top cover 320. Since the upper and lower ends of the elastic element (E) engage the first and second hooks 323 and 373, the elastic element (E) can apply a restorative force to the rod 370, when the rod 370 is moved down. In detail, when the rod 370 is moved down by means of the clamping element 380, the elastic element (E) is stretched, because the upper and lower ends of the elastic element (E) are geared first and second hooks 323 and 373. Therefore, when the compression force of the clamping element 380 is missing, the rod 370 is returned to its original position under the action of the reducing efforts of elongated elastic element (E).

Rod 370 further comprises a rectangular air holes 374 along its on uenoi surface. The air entering the filter 350 is directed through air holes 374 to the outlet 322 of the upper cover 320. Preferably the number and size of air holes are regulated so that it was possible to direct the air without interference.

Further detail will be described the operation of the vacuum cleaner and dust collection device with reference to figures 1-5. In particular, figure 5 depicts a side view in section, showing the dust collection unit of a vacuum cleaner when paleobotany element powered by a dust collection device in accordance with the present invention.

When the vacuum cleaner is turned on, the motor (not shown)installed in the main body 200 rotates and generates a suction force.

Under the action of the suction force of the electric motor, the air containing the foreign objects that are absorbed through the node 100 of the suction brush, and the intake air is directed suction guiding element 312 dust collection device 300 in the dust collection container 310.

In dust capacity 310 air rotates along the inner wall of the dust collection vessel 310. During the rotation of the air is relatively heavier foreign objects pass through the apertures 362 for the passage of foreign objects separator plate 360 to the bottom of the dust tank 310, and relatively light objects bremaud is along the circumference of the filter 350 and filtered out by the filter 350.

After rotation along the inner wall of the dust collection capacity 310 air passes through the filter 350 and extends on the outer side of the filter 350 through the air holes 374 and the exhaust port 322 to the outer side of the dust collection device 300. The air is produced on the outer side of the dust collection device 300, passes through the motor, and then the air comes out of the vacuum cleaner through the exhaust opening 290 formed on the outer surface of the main body. Thus a vacuum cleaner works.

Meanwhile, if foreign objects are accumulated in the dust collection capacity 310 with a low density, the volume of accumulated foreign objects obtained a relatively large when compared with the number of accumulated foreign objects. Therefore, the accumulated foreign objects occupy much space in dust capacity 310 that is unsightly and reduces the efficiency of dust collection dust collection device 300. To prevent these problems is driven paleobotany element (P) for sealing the foreign objects accumulated with low density.

To actuate paleopathology element (P), first of all, remove the presser element 380 of the handle 314. Then the lower end of the clamping element 380 is installed in the upper end of the rod 370, while the upper end ol imnogo element 380 is clamped in his hand.

The lower end of the clamping element forms a contact with the upper surface of the base flange 372 rod 370, thus, the rod 370 can be moved down when the user clicks on the pressure element 380.

When moving rod 370 down the dividing plate 360, connected with the lower end of the rod 370, also moves down. When the movement of the separation plate 360 down the dividing plate 360 compacts foreign objects accumulated on the bottom of the dust collection vessel 310 to reduce the volume of accumulated foreign objects, i.e. to increase their density.

Meanwhile, when the control force acting on the pressure element 380, eliminate after compaction of accumulated foreign objects, rod 370 and the partition plate 360 are moved upward to their original position under the action of the reducing efforts of the elastic element (E). Consequently, the dust-collecting device 300 could work again.

In accordance with the present invention can effectively utilize the inner space of the dust collection capacity so less often to empty dust container. In addition, since foreign particles collected in the dust collection capacity, sealed, dust is formed when emptying the dust container. Moreover, the operation of collecting foreign objects under the action of war the first air flow is not disturbed collected foreign objects, since the collected foreign objects tightly compressed. Thus, the efficiency of collecting foreign objects can persist for a long time.

In addition, the collected foreign objects tightly compressed in a predetermined location, so that the appearance can be improved.
