[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Example 1

[0025] refer to Figures 1 to 7 The dust cup of this embodiment includes a shell 1, a cover 2, a switch assembly 3, and an end cap 5.

[0026] The dust cup can store dirt, and the end cap 5 is installed on one end of the outer casing 1 and covers that end. The end cap 5 is provided with a dust discharge port. When the dust discharge port is not blocked, the dirt in the dust cup can be discharged through the dust discharge port.

[0027] The dust cup in this embodiment also includes a torsion spring 4. A torsion spring seat 21 is provided near one side of the cover 2. A first shaft segment 211 and a second shaft segment 212 are provided on both sides of the torsion spring seat 21. The main body of the torsion spring 4 is fitted onto the first shaft segment 211 of the torsion spring seat 21.

[0028] The second shaft section 212 of the torsion spring seat 21 is rotatably fitted onto the end cover 5, that is, the cover 2 is rotatably disposed on the end cover 5. The size of the cover 2 matches the dust discharge port. Under the action of the torsion spring 4, the cover 2 can cover the dust discharge port under normal conditions.

[0029] The torsion spring 4 is also provided with a first connecting arm 41 and a second connecting arm 42. The cover 2 is also provided with a locking block 22, and the locking block 22 is provided with a locking groove 23. The first connecting arm 41 is locked in the locking groove 23, and the second connecting arm 42 is locked in connection with the end cover 5.

[0030] The switch assembly 3 includes a stop member 31, an elastic member 32, and a housing 33. The housing 33 is fixedly mounted on the end cover 5 by bolts, and the housing 33 is provided with a receiving groove 331, in which the stop member 31 is movably disposed.

[0031] The stop member 31 has a receiving space 311 inside, and the elastic member 32 is preferably a spring. The elastic member 32 is located inside the receiving space 311, and a protrusion 314 is provided on one inner wall of the receiving space 311. One end of the elastic member 32 is fixedly connected to the protrusion 314, that is, the end of the spring 32 is fixed to the stop member 31.

[0032] The housing 33 is also provided with a stand block 333, which is also located in the accommodating space 311. The other end of the elastic element 32 is fixedly connected to the stand block 333, that is, the end of the spring 32 is fixedly connected to the housing 33.

[0033] The stop member 31 has a stop portion 312 on its side, and the cover member 2 also has an abutment portion 24. The abutment portion 24 is located on one side of the cover member 2, which is the opposite side to the side adjacent to the torsion spring seat 21.

[0034] The stop 31 can move relative to the housing 33 between a first position and a second position.

[0035] When the stop member 31 is in the first position, the stop part 312 can abut against the abutting part 24. At this time, the stop member 31 can stop the cover member 2, and the cover member 2 cannot rotate on the end cover 5. That is, the switch assembly 3 can lock the cover member 2 on the end cover 5.

[0036] When the stop 31 is in the second position, the stop part 312 separates from the abutment part 24, the stop 31 no longer restricts the cover 2, and the cover 2 can rotate on the end cover 5, thereby unlocking the cover 2 on the end cover 5.

[0037] Under normal conditions, the stop member 31 can be in the first position under the action of the elastic member 32. That is, under normal conditions, the elastic member 32 can maintain the stop member 31 locking the cover member 2, and the stop member 31 can move from the first position to the second position under the action of external force.

[0038] The stop member 31 is also provided with a guide ramp 313. The guide ramp 313 facilitates the connection between the stop member 31 and the external driving member. In a specific implementation, the driving member can be set on the base station, and the driving member can be a cylindrical pin, etc. When the vacuum cleaner with the above-mentioned dust cup is placed on the base station, the driving member can be connected to the guide ramp 313, so that the driving member can act on the guide ramp 313 to drive the stop member 31 to move.

[0039] In this embodiment, the dust cup can hold dust, garbage and other dirt when in use. Under normal conditions, the cover 2 can cover the dust outlet under the elastic action of the torsion spring 4, and the stop 31 is in the first position under the elastic action of the elastic member 32, so that the stop part 312 abuts against the abutting part 24 so that the switch assembly 3 locks the cover 2 on the end cover 5. Thus, even if there is a lot of dirt in the dust cup, the cover 2 can be effectively prevented from falling off the dust outlet.

[0040] When a cleaning device with this dust cup installed, such as a vacuum cleaner, is connected to a base station that collects dirt, the driving component on the base station, such as the cylinder piston rod, can contact the guide slope 313 and apply a force to the guide slope 313 to overcome the elasticity of the elastic component 32, causing the stop 31 to move from the first position to the second position. Then the stop 312 separates from the abutment 24, and the switch assembly 3 no longer locks the cover 2.

[0041] Then, the negative pressure suction device on the base station, such as the suction motor, generates suction. The suction can overcome the elasticity of the torsion spring 4, causing the cover 2 to rotate so that it no longer covers the dust discharge port. The dust discharge port opens, and the dirt in the dust cup can enter the base station under the action of suction.

[0042] After the dust cup is cleaned, the negative pressure suction device of the base station stops working. At this time, the cover 2 can be re-covered on the dust outlet under the elastic action of the torsion spring 4. Then the base station's drive component separates from the guide slope 313, and the stop 31 can move back to the first position under the elastic action of the elastic component 32. Then the switch assembly 3 locks the cover 2 onto the end cover 5 again.

[0043] Example 2

[0044] refer to Figures 1 to 7 The cleaning device of this embodiment includes a body and a dust cup as described in Embodiment 1. The body is preferably a vacuum cleaner body, and the dust cup can be installed on the body by snap-fit ​​or threaded fit.

[0045] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
