The fixed shaft 232 may protrude upward from the bottom surface of the dust collecting body 210. The second pressing plate 231 may be integrally formed on the inner circumferential surface of the dust collecting body 210 or the bottom surface of the dust collecting body 210.

The rotation shaft 222 includes an outer wall 241 and an inner wall 242. The inner wall 242 is spaced apart from the outer wall 241. The inner wall 242 is inserted into the fixed shaft 232, and the outer wall 241 surrounds the outer side of the fixed shaft. The outer wall 241 removes a gap between the fixed shaft 232 and the first pressing plate 221. Therefore, it is possible to prevent foreign substances such as hair from being caught between the fixed shaft 232 and the first pressing plate 221. In addition, foreign matters such as hair are prevented from being wound on the fixed shaft 232. Therefore, there is no need to remove foreign matters such as hair wound around the fixed shaft 232.

Meanwhile, the first cleaning member 223 may be located between the side surface of the first pressing plate 221 and the inner circumferential surface of the dust collecting body 210.

The second cleaning member 228 may be located between the bottom surface of the first pressing plate 221 and the bottom surface of the dust collecting body 210.

That is, one side of the first pressing plate 221 is formed integrally with the rotating shaft 222, the other side is the first cleaning member 223 is coupled. Of course, one side of the first pressing plate 221 may be combined with the rotation shaft 222. Each of the cleaning members 223 and 228 may be formed of a rubber material having elasticity, and other materials may be used. For example, felt may be used as each of the cleaning members 223 and 228.

In this embodiment, the material of each of the cleaning members 223 and 228 is not limited. The cleaning member may be slidingly coupled to the side portion of the first pressing plate 221 or integrally formed by insert injection.

In the present embodiment, there is no limitation in the coupling manner between the cleaning members 223 and 228 and the first pressing plate 221.

Since the shapes of the first cleaning member 223 and the second cleaning member 228 are the same in this embodiment, only the structure related to the first cleaning member will be described below, and the structure of the second cleaning member will be described. The description of will be omitted.

The receiving end 221a for accommodating the first cleaning member 223 is formed at the side end portion of the first pressing plate 221. A plurality of separation prevention parts 221b are formed at side ends of the first pressing plate 221 to prevent separation of the first cleaning member 223 accommodated in the accommodation part 221a.

The first cleaning member 223 includes a body portion 224 at least partially accommodated in the accommodation portion 221a, a contact portion 225 in contact with an inner wall of the dust collecting body, and A connection portion 226 connecting the body portion 224 and the contact portion 225 is included.

The connection part 226 may be deformed so as to absorb the frictional force that the contact part 225 receives when the rotation direction of the first cleaning member 223 is changed.

The body portion 224 includes a plurality of insertion portions 227 into which the separation prevention portions 221b are inserted. The insertion part 227 may be formed to be recessed to a predetermined depth from the outside of the body part 224.

When the body portion 224 is accommodated in the accommodation portion 221a, the separation prevention portion 221b is inserted into the insertion portion 227. Therefore, the body part 224 may be prevented from being separated in the lateral direction of the first pressing plate 221 by the separation preventing part 221b. The contact portion 225 may be formed such that the horizontal cross-sectional area decreases toward the inner wall of the dust collecting body 210 from the connection portion 226 side. That is, the contact portion 225 is formed so that the thickness becomes thinner from the portion connected from the connecting portion 226 to the end portion. For example, it may be formed in a triangular shape, but is not limited thereto.

In order to facilitate relative movement of the contact portion 225 and the body portion 224, the connection portion 226 has a hollow. And, the hollow is formed in the vertical direction of the connecting portion 226. Accordingly, the connection part 226 rotates while the contact part 225 is in contact with the inner circumferential surface of the dust collecting body 210, and when changing the rotation direction, absorbs the frictional force received by the end part through the deformation. do. When the outer shape of the connection part 226 is deformed in this way, the position of the contact part 225 is changed. Accordingly, the contact portion 225 slides the inner circumferential surface of the dust collecting body 210 in accordance with the rotational direction that is reversely rotated, and the connection portion 226 is restored to its shape again. When viewed as a whole, the first cleaning member 223 may be easily deformed by the connection part 226.

On the other hand, the distance from the rotation center line of the first pressing member 220 to the contact portion 225 is greater than the distance between the inner circumferential surface of the dust collecting body 210 from the rotation center line of the first pressing member 220. Therefore, when the first pressing member 220 rotates inside the dust collecting body 210, the contact portion 225 may be changed in position with respect to the body portion 224 by the connecting portion 226. .

The horizontal distance from the body portion 224 to the end portion of the contact portion 225, that is, the horizontal length of the first cleaning member 223 may be varied by the connection portion 226. That is, since the connection portion 226 has a hollow, the connection portion 226 is variable in shape by the hollow, the distance between the body portion 224 and the contact portion 225 is variable. Therefore, even when an obstacle (foreign material) is located on the movement path of the contact part 225, the contact part 225 may easily cross the obstacle by changing the shape of the connection part 226. Of course, the contact portion 225 may move while pushing the obstacle.

Meanwhile, referring to FIG. 6, the first pressing member 220 may be rotated by the driving device.

In detail, the driving device includes a driving source for generating a driving force, and a power transmission unit 410 for transmitting the driving force of the driving source to the first pressing member 220. As the driving source, a compression motor (not shown) may be applied. The compression motor may be provided inside the main body.

Here, the compression motor may be a motor capable of bidirectional rotation. As such, in order to enable forward and reverse rotation of the compression motor, a synchronous motor may be used as the compression motor. The synchro-motor is configured to be capable of forward and reverse rotation by the motor itself, and when the force applied to the motor is greater than or equal to a predetermined value when the motor rotates in one direction, the rotation of the motor is converted to the other direction. .

Hereinafter, the operation of the vacuum cleaner and the compression process of the dust according to the present embodiment will be described.

9 is a horizontal sectional view of the dust collecting body when the first pressing member is rotated in the clockwise direction.

1 to 9, when the first pressing member 220 is rotated by the driving of the compression motor (not shown) inside the dust collecting body 210, the first cleaning member 223 is It rotates together with the first pressing plate 221. At this time, the contact portion 225 is deformed by the connection portion 226 is maintained in contact with the inner peripheral surface of the dust collecting body (210). By rotating the contact portion 225 in contact with the inner circumferential surface of the dust collecting body 210, dust or sand deposited on the inner circumferential surface of the dust collecting body 210 may be removed.

In addition, the gap between the first pressing plate 221 and the inner wall of the dust collecting body 210 is removed by the first cleaning member 223. Therefore, the sand or the foreign matter is prevented from being located between the first pressing plate 221 and the dust collecting body 210, the noise generated by the friction between the sand or foreign matter and the dust collecting body 210 can be removed. have.

When the first pressing plate 221 rotates in the clockwise direction as shown in FIG. 9, the contact part 225 receives a force in the counterclockwise direction. Accordingly, the connecting portion 226 of the first cleaning member 223 has a cross-sectional shape that is deformed from circular to elliptical and is bent in a counterclockwise direction.

Since the connection part 226 of the first cleaning member 223 has a hollow, the shape of the connection part 226 also changes easily as the rotation direction of the pressure plate 221 changes.

Therefore, there is an effect that the life of the first cleaning member 223 is extended compared to when the connection portion 226 does not exist.

On the other hand, when the first pressing member 220 is rotated, the second cleaning member 228 cleans the bottom surface of the dust collecting body. In addition, the second cleaning member 228 contacts the outer wall 241 of the rotation shaft 222. Therefore, when the first pressing member 220 is rotated, it is possible to prevent the foreign material such as hair to be wound on the outer wall 241.
