6 is a perspective view of a cover member according to an embodiment of the present disclosure; 7 is a view illustrating a state in which the cover member is connected to the opening/closing member. 8 is a view showing a state in which the cover member is rotated.

6 to 8 , the cover member 300 is rotatably connected to the fixed region 310 fixed to the opening/closing member 200 and the fixed region 310 , and the stopper member 400 is formed. It may include a rotation region 320 .

The stopper member 400 may contact the fixing region 310 of the cover member 300 as the cover member 300 rotates. Meanwhile, the object that the stopper member 400 comes into contact with is not limited thereto, and may come into contact with the opening/closing member 200 .

Accordingly, the cover member 300 cannot rotate more than a preset angle. That is, regardless of the intensity of the suction force generated by the driving device 10 , the cover member 300 may rotate only by a designated angle by the stopper member 400 .

For example, when the driving device 10 is operated, the cover member 300 may rotate only by a preset angle within a range of 30 degrees to 40 degrees. However, the rotation angle of the cover member 300 is not limited thereto.

Accordingly, the same flow path area may be secured between the head member 20 and the dust collector 100 regardless of the suction force of the driving device 10 .

In addition, since the elastic cover member 300 does not rotate more than a predetermined angle, the deformation of the cover member 300 is minimized and the elasticity can be continuously maintained.

The rotation region 320 of the cover member 300 may be formed of a soft material, and the fixed region 310 and the stopper member 400 of the cover member 300 are made of a material having greater rigidity than the rotation region 320 . can be formed.

Accordingly, when the cover member 300 rotates, the fixing region 310 and the stopper member 400 do not slide or deform to each other, and may stably contact each other while maintaining a fixed shape.

The rotation region 320 of the cover member 300 includes a central region 321 and a peripheral region 322 disposed to surround the central region 321 and seated on the upper surface 201 of the opening/closing member 200 . can do. The peripheral region 322 may have a smaller thickness than the central region 321 .

Since the central region 321 of the cover member 300 has a thick thickness, it may not be easily deformed even by a strong suction force. Accordingly, the cover member 300 may rotate stably while maintaining its shape to open the opening 210 of the opening/closing member 200 .

Since the peripheral region 322 of the cover member 300 has a thin thickness, it may be easily deformed. Accordingly, even if small dust is on the upper surface 201 of the opening and closing member 200 , the peripheral region 322 can be completely in close contact with the upper surface of the opening and closing member 200 as its shape is deformed corresponding to the dust. That is, when the driving device 10 is turned off and the cover member 300 returns to its original state, as the peripheral region 322 is easily deformed, the cover member 300 closes the opening 210 of the opening and closing member 200 completely. can

The opening/closing member 200 may include a fixing hole 220 , and the fixing region 310 may include a protrusion 311 that is formed to protrude upward and is inserted into the fixing hole 220 . Accordingly, the fixing region 310 of the cover member 300 may be stably coupled to the opening and closing member 200 without being separated from the opening and closing member 200 .

Also, the cover member 300 may be connected to the rear side of the opening/closing member 200 . Accordingly, when the user finishes cleaning with the dust collector 100 tilted backward (refer to FIG. 9 ), even if the dust in the first dust collecting chamber 110 falls downward due to gravity, the dust is the most Since the rear side of the opening 210 of the opening/closing member 200, which falls first, is already closed by the cover member 300 , the dust in the first dust collecting chamber 110 flows into the suction flow path 21 of the head member 20 . spillage can be minimized.

The stopper member 400 may be disposed to be inclined upwardly toward one end 301 connected to the opening/closing member 200 of the cover member 300 .

Specifically, the stopper member 400 includes an inclined region 410 and an inclined region 410 having one end connected to one surface of the cover member 300 and inclined upward toward the one end 301 of the cover member 300 . It may include a support region 420 extending from the other end and inclined downwardly toward one end 301 of the cover member 300 .

That is, by the stopper member 400 having the above-described shape, the support region 420 may be stably supported while in contact with the fixing region 310 or the opening/closing member 200 over a large area.

The stopper member 400 may be in vertical contact with the opening/closing member 200 or the cover member 300 as the cover member 300 rotates. Accordingly, even when a strong suction force is applied to the cover member 300 , the stopper member 400 is stably supported by the opening/closing member 200 or the cover member 300 , so the cover member 300 can maintain the rotation angle. have.

Meanwhile, the cleaner 1 may further include a sealing member 230 disposed to surround the opening/closing member 200 and sealing between the dust collector 100 and the opening/closing member 200 .

The sealing member 230 may be disposed along the edge of the opening and closing member 200 . The sealing member 230 may include a material having elasticity. The sealing member 230 may be formed of a material that is more flexible than the opening/closing member 200 .

The sealing member 230 may be in close contact with the inner surface of the case 101 to seal the first dust collecting chamber 110 . Accordingly, the cleaner 1 according to the exemplary embodiment of the present disclosure may prevent dirt from being discharged from the first dust collecting chamber 110 .

9 is a view showing a state of emptying the dirt of the dust collector of FIG. 1 . 10 is a cross-sectional view of a portion of the cleaner of FIG. 9 .

9 and 10 , when the user wants to empty the dust collected in the dust collector 100 after completing the cleaning operation, the user pushes the extension member 30 downward while pressing the second button 32 . It can be pushed and slid with respect to the dust collector 100 .

In this case, the extension member 30 , the driving device 10 , the second dirt removing member 150 , the first dirt removing member 130 , and the opening/closing member 200 integrally connected to each other may all move downward together.

When the extension member 30 slides inside the dust collector 100 , the opening/closing member 200 disposed at one end of the extension member 30 opens the first dust collecting chamber 110 , and the first and The second

dirt removing members

130 and 150 may slide to discharge the dirt in the first and second

dust collecting chambers

110 and 120 to the outside. In addition, the second dirt removing member 150 may discharge the dirt of the second dust collection chamber 120 to the outside and simultaneously discharge the dirt existing in the first dust collection chamber 110 secondarily. To this end, the first and second

dirt removal members

130 and 150 may move to a position where they protrude to the outside of the dust collector 100 .

Thereafter, when the dust discharge of the first and second

dust collecting chambers

110 and 120 is completed, the user may move the extension member 30 in a direction to be drawn out from the dust collecting device 100 , and accordingly, the opening/closing member ( 200 may move to a position to close the first dust collection chamber 110 .

According to this configuration, the cleaner 1 according to the embodiment of the present invention can easily empty the dirt of the dust collector 1000 through a relatively simple operation. In addition, since the opening/closing member 200 is provided to open and close the first and second
