Referring to fig. 1, 3 and 5, the bottom cover of the dust cup is unlocked as follows: the pressing force acts on the pressing portion 32 of the release button 3, the release button 3 rotates, the lower portion (the first buckle 51 portion) of the release button 3 tilts by utilizing the lever principle, the first buckle 51 moves in the direction away from the second buckle 52, meanwhile, the spring 10 is compressed, the buckle mechanism 5 is unlocked (namely, the first buckle 51 and the second buckle 52 are separated), at this time, the pre-compressed driving member 41 restores to the original state to generate an elastic force, the driving member 41 pushes the pushing member 43 to move downwards (the direction shown by the arrow a in fig. 1), and the protruding block 432 moves in the direction of the first limiting block 421, so that the abutting end 5 presses the abutting portion 61, the bottom cover 2 is pushed to open, and dust is poured out. When the external force is removed, the release button 3 is reset under the action of the spring 10.

The bottom cover locking mode is as follows: after the use, the bottom cover 2 is pushed by an external force to rotate towards the cup body 1, specifically, the external force applying position is close to the pressing portion 61, the bottom cover 2 moves towards the dust outlet 12, the pressing portion 61 contacts with the pressing portion 5 and then pushes the pressing end 5 to move upwards (in the reverse direction of the direction indicated by the arrow a in fig. 1), the driving member 41 is gradually compressed until the locking mechanism 5 is locked (i.e., the first buckle 51 and the second buckle 52 are clamped), and the bottom cover 2 is locked on the cup body 1.

In summary, the dust cup is provided with the release button 3 and the pushing assembly, so that when the release button 3 is unlocked, the driving member 41 in the pushing assembly drives the pushing member 43 to push the bottom cover 2, so as to open the bottom cover 2, therefore, the dust cup can complete the opening of the dust outlet 12 only by applying a pressing force on the release button 3, and the required pressing force is small.

In a preferred embodiment, the receiving groove 7 is formed by extending a part of the outer wall of the cup body 1 outward, so that the inner wall of the cup body near one end of the bottom cover is in a substantially smooth circular ring shape. Simultaneously, first axial region 14 is also outwards convex relative cup 1's outer wall to guarantee that the lower extreme of the inner wall of cup is basic ring form, like this, both can increase the volume of dirt cup, can effectively prevent again that the dust from gathering in this department, if storage tank 7 and first axial region 14 all inwards cave in, the position of indent has the dust gathering, inconvenient deashing, the easy deposition of time of having of a specified duration, and be difficult to the clearance.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
