When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0039] Referring to Figures 1-7, a cleaning system 100 is disclosed, which includes a vacuum cleaner 1 and a base station 2. The vacuum cleaner 1 includes a motor assembly for generating a suction airflow and a dust cup assembly 20 for storing dirt. The dust cup assembly 20 includes a primary dust storage chamber. The primary dust storage chamber 21 is provided with a first opening 22 and a first cover 23 that can close / open the first opening 22. The base station 2 is used to dock at least part of the vacuum cleaner 1, and the dirt in the dust cup assembly 20 can be transferred from the first opening 22 to the base station 2. A suction motor can be provided in the base station 2, and the airflow generated by the suction motor can transfer at least part of the dirt in the dust cup assembly 20 to the dust bag or dust removal device of the base station 2. Of course, the dirt in the dust cup assembly 20 can also be emptied into the base station 2 in other feasible ways.

[0040] In one embodiment, the first cover 23 is in an openable state after the vacuum cleaner 1 is docked to the base station 2. The openable state means that the first cover 23 can still cover the first opening 22 in a loose state when no external force is applied (see Figure 5). When the first cover 23 receives other external forces such as suction, the first opening 22 can be opened (see Figure 6). Specifically, when the first cover 23 is in an openable state, it can open the first opening 22 under the action of the airflow generated by the suction motor. In order to enable the first cover 23 to be locked when the vacuum cleaner 1 is in normal use. The dust cup assembly 20 also includes a locking structure 24 for locking / unlocking the first cover 23. The locking structure 24 is configured to be in an unlocked state after the vacuum cleaner 1 is docked to the base station 2; the locking structure 24 is also configured to change from an unlocked state to a locked state after receiving a force from the base station 2 when the vacuum cleaner 1 is detached from the base station 2.

[0041] Referring to Figure 7, specifically, the locking structure 24 is L-shaped and includes a connected vertical section 25 and a horizontal section 26. The end of the vertical section 25 away from the horizontal section 26 is pivotally mounted to the cup body of the dust cup assembly 20. The dust cup assembly 20 includes a bottom wall 27 and a side wall 28. The horizontal section 26 is substantially flush with the bottom wall 27 when the locking structure 24 is in the locked state; the vertical section 25 is substantially flush with the side wall 28 when the locking structure 24 is in the locked state; and the intersection of the horizontal section 26 and the vertical section 25 protrudes from the side wall 28. A receiving slot is generally provided in the base station 2, and the locking structure 24 is at least partially located in the receiving slot when in the open state. When the dust cup assembly 20 is removed from the base station 2, the upper wall of the receiving slot will squeeze the vertical section 25 of the locking structure 24, so that the locking structure 24 can pivot to move to the locked position and lock the first cup cover.

[0042] Because the movement between the locking structure 24 and the inner wall of the base station 2 creates compression and can cause wear over time, the base station 2 is provided with a roller. The roller is configured to contact the vertical section 25 when the vacuum cleaner 1 is separated from the base station 2, thereby exerting a force on the locking structure 24 to shift it from an unlocked state to a locked state. Alternatively, in another embodiment, the locking structure 24 is provided with a roller, which is configured to contact the base station 2 when the vacuum cleaner 1 is separated from the base station 2. The presence of the roller can make the movement between the two smoother.

[0043] Referring to Figure 3, an unlock button 32 is provided on the bottom wall 27 of the dust cup assembly 20. The unlock button 32 is configured so that after the vacuum cleaner 1 is docked to the base station 2, the unlock button 32 is pushed to change the locking structure 24 from a locked state to an unlocked state. When the vacuum cleaner 1 is placed on the base station 2, the unlock button 32 is always pressed and will not be reset. When the vacuum cleaner 1 is detached from the base station 2, the unlock button 32 is reset, at which point the locking structure 24 can lock the first cup cover again.

[0044] Referring to Figure 4, in a further embodiment, the dust cup assembly 20 includes a secondary dust chamber 29, which is provided with a second opening 30 and a second cover 31 that can close and open the second opening 30. The second cover 31 is positioned directly above the first cover 23. The second cover 31 is suspended relative to the first cover 23. When the second cover 31 is open, dust within the secondary dust chamber 29 is transferred to the primary dust chamber. The first cover 23 is positioned below the second cover 31, and at least a portion of the primary dust chamber is defined between the first and second covers 23 and 31. The second cover 31 can open the second opening 30 in response to airflow generated by the suction motor. The second opening 30 is positioned above the first opening 22, effectively ensuring the area of ​​the first opening 22 and facilitating smoother discharge of dirt. Furthermore, the second cover 31 is not positioned above the first cover 23 to prevent dirt (such as long hair or fluff) from catching on the second cover 31.

[0045] In another embodiment, the first cover 23 can be configured to be in an open state after the vacuum cleaner 1 is docked to the base station 2. In this state, the first cover 23 no longer requires suction and remains in the open state. When the vacuum cleaner 1 is detached from the base station 2, the first cover 23 moves from the open position to the closed position under the force of the base station 2. For example: the first cover 23 can be set on the side wall 28 of the dust cup assembly 20, so that the first cover 23 pivots outward to open the first opening 22 located on the side wall 28. When the dust cup assembly 20 leaves the base station 2, the base station 2 applies a force to the first cover 23, so that the first cover 23 can be closed. In other embodiments, the first cover 23 can also be set to the bottom wall 27 of the cup body, but the way of taking and placing the vacuum cleaner 1 needs to be changed, and its removal direction needs to be coordinated with the closing direction of the first cover 23.

[0046] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. 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 illustrations shown and described herein.
