8 is a cross-sectional view showing the structure of a lower handle according to the present invention, Figures 9 and 10 are a plan view showing a dust compression process in the dust collecting container according to the present invention.

8 to 10, a guide groove 254 is formed inside the lower handle 252 to guide the movement of the protrusion (see 412 of FIG. 5) formed on the side of the lever.

The guide groove 254 is formed to be rounded to correspond to the trajectory of the protrusion 254 when the protrusion 412 moves. In addition, a fixing groove 256 is formed at the upper end of the guide groove 254 to be fixed in a state where the protrusion 412 is positioned.

That is, when the protrusion 412 moves upward along the guide groove 254 and is positioned in the fixing groove 256, the protrusion 412 is maintained in a fixed position, and thus the lever ( The position of 410 is fixed.

Here, the state in which the protrusion 412 is located in the guide groove 254 is a state in which the lever 410 is pulled backward, and in the state in which the lever 410 is pulled backward, the first pressing member 310 and As shown in FIG. 9, the second pressing member 320 is fixed by being rotated about 180 degrees from the third pressing member 330.

Here, in the present invention, during the cleaning, as shown in Figure 9, the lever 410 is moved to the rear to maintain a fixed position, and the fixing of the lever 410 by the state of cleaning or the user's intention is completed When released, the transmission member 420 is moved forward by the restoring force of the restoring spring, as shown in Figure 10, the first pressing member 310 and the second pressing member 320 is the third pressing member 330 Rotate to the side to compress the dust.

Hereinafter, the operation of the dust collecting device according to the present invention will be described in detail.

First, the user pulls the lever 410 before starting cleaning. Here, the first pressing member 310 and the second pressing member 320 before the lever 410 is pulled are positioned close to the third pressing member 330.

Then, the protrusion 412 of the lever 410 is moved in a direction away from the dust collecting container 250 along the guide groove 254.

Hereinafter, the direction in which the lever 410 moves away from the dust collecting container 250 is referred to as "rear", and the direction of approaching the dust collecting container 250 as "front".

In addition, when the protrusion 412 is located in the fixing groove 256, the lever 410 is fixed in a position moved backward.

In addition, when the lever 410 is moved to the rear, the transmission member 420 connected to the lever 410 is moved to the rear.

In detail, when the transmission member 420 is moved backward, the drive gear 430 is rotated in the counterclockwise direction, the first driven gear 440 is rotated in the clockwise direction.

In addition, when the first driven gear 440 is rotated in the clockwise direction, the second pressing member 320 coupled with the first driven gear 440 is rotated in the clockwise direction.

On the other hand, when the transmission member 420 is moved backward, the drive gear 430 is rotated in the counterclockwise direction, the intermediate gear 450 is rotated in the clockwise direction, the second driven gear 460 is Rotate counterclockwise. Then, the first pressing member 310 coupled with the second driven gear 460 is rotated counterclockwise.

In this way, the lever 410 is pulled and generated when the suction motor is operated while the first pressing member 310 and the second pressing member 320 are rotated in a direction away from the third pressing member 330. Air containing dust is sucked into the suction nozzle by the suction force.

In addition, the air sucked through the suction nozzle is introduced into the cleaner body 100 through the main body suction part 110, and the introduced air is introduced into the dust collector 200 through a predetermined flow path.

In detail, the air containing the dust is sucked in the tangential direction of the cyclone 211 through the inlet 212 of the dust separation unit 210. Then, the sucked air falls while turning along the inner circumferential surface of the cyclone 211, in which air and dust are separated from each other while being subjected to different centrifugal forces by the weight difference.

Then, the dust is separated air is filtered through the through hole 272 of the exhaust member 270, and is discharged to the outside of the dust collector 200 through the discharge hole 262.

On the other hand, the separated dust is dropped downward through the opening 231 in the process of turning along the inner circumferential surface of the cyclone 211 is stored in the dust storage unit 251.

Meanwhile, in order to clean the dust or compress the dust by the user's intention, the first pressing member 310 and the second pressing member 320 are rotated toward the third pressing member 330.

In detail, when the lever 410 is further pulled backward, the protrusion 412 is released from the fixing groove 256. In addition, the protrusion 412 is released from the fixing groove 256 to release the lever 410 to remove the pulling force of the lever 410.

Then, the transmission member 420 is moved forward by the restoring force of the restoration spring 410, and the lever connected to the transmission member is moved forward. Here, since the tension spring is used as the restoring spring 470, when the force pulling the lever 410 is removed, the restoring spring 470 moves in the contracted direction.

When the transmission member 420 is moved forward, the driving gear 430 is rotated clockwise, and the first driven gear 440 is rotated counterclockwise. When the first driven gear 440 is rotated counterclockwise, the second pressing member 320 coupled with the first driven gear 440 is rotated counterclockwise.

As described above, when the second pressing member 320 is rotated counterclockwise, the second pressing member 320 removes dust between the second pressing member 320 and the third pressing member 330. 3 is pressed toward one side of the pressing member 330 to compress the dust.

On the other hand, when the transmission member 420 is moved forward, the drive gear 430 is rotated in the clockwise direction, the intermediate gear 450 is rotated in the counterclockwise direction, the second driven gear 460 is Rotate clockwise. Then, the first pressing member 310 coupled with the second driven gear 460 is rotated in the clockwise direction.

As described above, when the first pressing member 310 is rotated in the clockwise direction, the first pressing member 320 may remove dust between the first pressing member 310 and the third pressing member 330 from the third pressing member 310. The dust is compressed by pushing toward the other side of the pressing member 330.

Such compression of the pressing member may be performed once by the user's intention, and may be performed a plurality of times.

Meanwhile, in order to empty the dust stored in the dust storage unit 251, the user separates the dust collecting apparatus 200 from the cleaner body 100. In addition, the dust collecting container 250 is separated from the dust separation unit 210. Then, the dust collecting container 250 is turned upside down to empty the dust.

As such, the user simply needs to flip the dust collecting container 250 and empty the dust so that the user can easily handle the dust collecting container 250.

In addition, since the dust is kept compressed in the dust storage unit 251, the dust is easily discharged, and the phenomenon of dust scattering in the process of discharging the dust is prevented.

In this embodiment, during the cleaning, the first pressing member and the second pressing member are kept separated from the third pressing member while the lever is pulled, and the pulling of the lever after the cleaning is released, whereby the first pressing member and the second pressing member are released. Compression of the dust is performed while the pressing member is moved. Alternatively, dust may be compressed by the first pressing member and the second pressing member in the process of pulling the lever.

That is, the first pressing member and the second pressing member are kept separated from the third pressing member while the lever is not pulled, and the first pressing member and the second pressing member are pulled by pulling the lever. Compression of the dust may be achieved while the member moves toward the third pressing member. In the case of such an embodiment, it may be achieved by changing the position of the first pressing member and the second pressing member in the initial manufacturing process of the dust collecting apparatus from the original embodiment.

According to the present invention as proposed, since the dust stored in the dust storage unit is compressed to minimize the volume, there is an effect that the capacity of the dust stored in the dust collector is maximized.

In addition, as the dust collecting capacity of the dust collecting device is maximized by the compression action of the dust, the user has to remove the trouble of frequently emptying the dust stored in the dust collecting device.

In addition, since the dust is kept in a compressed state in the dust collector, there is an effect that the scattering of dust in the process of emptying the dust is prevented.
