For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0021] refer to Figure 1 The present application discloses a cleaning system 100, comprising a vacuum cleaner 1 and a base station 3. The vacuum cleaner 1 comprises a motor assembly for generating a suction airflow and a dust cup assembly 11 for storing dirt. The base station 3 is used to dock at least part of the vacuum cleaner 1, and a suction motor is arranged in the base station 3. The airflow generated by the suction motor can transfer at least part of the dirt in the dust cup assembly 11 to the base station 3. Figure 2-5, the figure discloses a dust cup assembly 11, which includes a cup body 14. A storage space is defined in the cup body 14, and the storage space includes a primary cyclone separation chamber and a primary ash storage chamber 13. The suction airflow generated by the motor assembly of the vacuum cleaner 1 enters the storage space from the opening on the cup body 14, and begins to undergo cyclone separation in the primary cyclone separation chamber. The separated dirt is stored in the primary ash storage chamber 13, and the separated airflow passes through the filter screen and enters the secondary cyclone separator 15 for further filtration. The secondary cyclone separator 15 is arranged in the storage space, and includes a secondary cyclone separation chamber 16 and a secondary ash storage chamber 17. A plurality of cyclone cones may be arranged in the secondary cyclone separator 15, and the fine ash filtered by the cyclone cones is stored in the secondary ash storage chamber 17. This part is a conventional structure and will not be described in detail here. The difference from the prior art is that the suspended end of the secondary cyclone separator 15 is suspended relative to the bottom end of the cup body 14. The bottom end of the cup body 14 can be a cup cover, or can be a structure integrally formed with the side wall 24 of the cup body 14. The suspended end is provided with a second opening 20 and a second cover plate 21 that can close / open the second opening 20, wherein when the second cover plate 21 is in an open state, the dust in the secondary ash storage chamber 17 can enter the primary ash storage chamber 13 from the second opening 20. The difference in the above structures is mainly to facilitate the docking of the dust cup assembly 11 to the base station 3. When the second cover plate 21 is opened, the dust can smoothly enter the primary ash storage chamber 13 in the cup body 14, and then be transferred to the base station 3 through the opening of the primary ash storage chamber 13 without dirt getting stuck, so that the dirt in the cup body 14 can be discharged smoothly.

[0022] Continue to refer Figure 5 The cup body 14 is provided with a first opening 18 and a first cover plate 19 that can close / open the first opening 18. The first cover plate 19 is arranged below the second cover plate 21 and at least part of the primary dust storage chamber 13 is defined between the first cover plate 19 and the second cover plate 21. Because the second cover plate 21 is located above the first cover plate 19, this can effectively increase the passing area of ​​dirt, making the emptying of dirt smoother. In a specific embodiment, the first cover plate 19 is in an openable state or an open state after the vacuum cleaner 1 is docked to the base station 3; when the first cover plate 19 is in an openable state, it can open the first opening 18 under the action of the airflow generated by the suction motor. The dust cup assembly 11 also includes a locking structure 22 for locking / unlocking the first cover plate 19. The locking structure 22 is configured to be in an unlocked state after the vacuum cleaner 1 is docked to the base station 3, and the locking structure 22 changes from an unlocked state to a locked state when the vacuum cleaner 1 is separated from the base station 3.

[0023] refer to Figure 2-5The locking structure 22 is L-shaped, partly located on the bottom wall 23 of the dust cup assembly 11, and partly located on the side wall 24 of the dust cup assembly 11. Specifically, the locking structure 22 can be pivotally mounted on the side wall 24 of the cup body 14. When the L-shaped locking structure 22 tilts outward, the first cover plate 19 is in an unlocked state. When the dust cup assembly 11 leaves the base station 3, the base station 3 will exert a force on the locking structure 22. In this way, the locking structure 22 moves from the unlocked position to the locked position under the force of the base station 3, locking the first cover plate 19. It is convenient for the user to use it next time. Figure 6 As shown, when the dust cup assembly moves upward, the locking structure will be rubbed by the inner wall of the base station, so that the locking structure moves to the locking position.

[0024] Of course, in other embodiments, the first cover plate 19 is in an open state after the vacuum cleaner 1 is docked to the base station 3, that is, the cover plate can open the first cover plate 19 under a torsion spring or other mechanism. When the vacuum cleaner 1 is taken out, the first cover plate 19 can be moved from the open position to the closed position by applying a force to the first cover plate 19 by the base station 3. For example: the first cover plate 19 can be set on the side wall 24 of the dust cup assembly 11, so that the first cover plate 19 pivots outward to open the first opening 18 located on the side wall 24. When the dust cup assembly 11 leaves the base station 3, the base station 3 applies a force to the first cover plate 19, so that the first cover plate 19 can be closed. In other embodiments, the first cover plate 19 can also be set to the bottom wall 23 of the cup body 14, but the way of taking and placing the vacuum cleaner 1 needs to be changed, and its taking-out direction needs to be coordinated with the closing direction of the first cover plate 19.

[0025] In one embodiment, the second cover plate 21 is configured to close the second opening 20 without being affected by external forces; specifically, the second cover plate 21 can be pivotally mounted at the second opening 20, and the dust cup assembly 11 also includes a retaining structure, which is configured to enable the second cover plate 21 to overcome gravity to keep it in a closed state; the retaining structure can be a torsion spring, and of course, it can also be other structures with elastic functions. The second cover plate 21 can also be a soft rubber cover plate installed at the second opening 20, and the second opening 20 can be automatically closed through the elastic function of the soft rubber. When the suction motor of the base station 3 is started, the airflow generated can overcome the force generated by the retaining mechanism to open the second cover plate 21.

[0026] In another embodiment, the second cover plate 21 is configured to open the second opening 20 without being affected by external force. Specifically, the second cover plate 21 is pivotally mounted at the second opening 20, and the second cover plate 21 is in an open state under the action of gravity to open the second opening 20. When the motor assembly of the handheld vacuum cleaner 1 is not started, the second cover plate 21 is in an open state, and when the motor assembly is working, the second cover plate 21 is closed under the action of suction.

[0027] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and implementation modes. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
