[0051] Reference Figures 1 - 14 , a dust cup assembly 1 is disclosed in the figure. The dust cup assembly 1 can be used for various vacuum cleaners 101, such as: upright vacuum cleaners 101, handheld vacuum cleaners 101 ( Figure 3 ), canister vacuum cleaners 101 ( Figure 2 ), or floor sweeping robots ( Figure 1 ), etc.

[0052] Reference Figures 3 - 14, taking the structure of the handheld vacuum cleaner 101 as an example, this text details the structure of the dust cup assembly 1 and its working principle in the vacuum cleaner 101. The handheld vacuum cleaner 101 generally includes a housing 102. Inside the housing 102, there is a suction motor 103 for generating a suction airflow (the arrow direction in the figure indicates the airflow direction). Inside the housing 102, there may also be a power battery 105 for supplying power to the suction motor 103. Of course, the suction motor 103 can also be powered by the municipal power supply. The housing 102 generally also defines a handle through which the user can control the handheld vacuum cleaner 101. Generally, there are buttons at the handle. Through the buttons, the user can control the operation, stop, and gear shifting of the suction motor 103 through a controller (usually a PCB board) inside the housing 102. The arrangement of the above structures is not defined in detail here, as long as the corresponding functions of the handheld vacuum cleaner 101 can be achieved.

[0053] Reference Figures 5 - 14 , this text discloses a dust cup assembly 1. The dust cup assembly 1 includes a cup body 11 and a filter. The cup body 11 is generally a cylindrical structure. Of course, the cup body 11 can also be of other shapes, which is not limited here. The cup body 11 defines a receiving space, which is generally divided into a separation chamber and an ash storage chamber. In some embodiments, the separation chamber and the ash storage chamber can be separately arranged and are connected through a dust throwing port. In other embodiments, the separation chamber and the ash storage chamber are in the same space. As Figure 6 shown, a filter is provided inside the cup body 11. The filter is generally a cyclone separator because the cyclone separator has a relatively high filtration efficiency. The space where the filter is located is the separation chamber, and the space below the filter is the ash storage chamber. A skirt 123 is provided at the lower edge of the filter. The skirt 123 extends towards the side wall and also towards the bottom wall of the cup body 11. The function of the skirt 123 can prevent the dust in the ash storage chamber from entering the separation chamber again, thereby improving the separation efficiency. Reference Figure 6 , the filter can include a primary filter 121 and a secondary filter 122 located downstream of the primary filter 121. This filter structure is relatively common and will not be elaborated here. The primary filter 121 is generally a columnar porous structure. In order to quickly and conveniently clean the fine ash, hair, and other dirt attached to the outer periphery of the filter, a dust scraping member 13 can be provided on the outer periphery of the filter. The dust scraping member 13 is configured to move between a dust scraping starting position and a dust scraping end position after being driven by an external force to clean the dust attached to the outer periphery of the filter. The dust scraping member 13 includes a dust scraping bracket 131 and a wiping member 132 provided on the dust scraping bracket 131. The wiping member 132 is generally made of rubber material and is fixed to the dust scraping bracket 131 by means of rubber coating. The wiping member 132 can also be made of other materials as long as its function can be achieved. Of course, in other embodiments, the wiping member 132 can also be detachably installed on the dust scraping bracket 131 for easy replacement.

[0054] Reference Figures 6 - 12 , in order to enable an external force to drive the ash scraping member 13, the dust cup assembly 1 further includes an extension member 133, a connecting member 135 and a guiding member 134. The extension member 133 is connected to the ash scraping member 13, and the connecting member 135 is connected to the extension member 133. Here, the connection can be a fixed connection or a transmission connection. The extension member 133 is disposed inside the side wall of the cup body 11, and the connecting member 135 moves together with the extension member 133. The cup body 11 is provided with an upper baffle 112 and a lower baffle 113. The guiding member 134 is disposed between the upper baffle 112 and the lower baffle 113, and the guiding member 134 is disposed outside the side wall of the cup body 11. An elastic member 136 is disposed between the upper baffle 112 and the lower baffle 113. The elastic member 136 generates a driving force to push the connecting member 135 to move along the guiding member 134, so as to drive the ash scraping member 13 to move from the ash scraping end position to the ash scraping starting position. The guiding member 134 can be a guide rod. When the guiding member 134 is a guide rod, the elastic member 136 is a spring structure, and at least part of the guiding member 134 is disposed inside the spring. The guiding member 134 can also be a groove-shaped guiding structure or other forms of guiding structures to guide the connecting member 135 to move along the axis direction of the filter. The elastic member 136 can be determined according to the structure of the guiding member 134, and no detailed limitation is made here. When an external force drives the ash scraping member 13 to move, since the connecting member 135 moves along the direction guided by the guiding member 134, it can effectively ensure that the ash scraping member 13 is parallel to the axis direction of the filter during the downward movement, realizing the smooth operation of the ash scraping member 13 along the surface of the filter and avoiding the ash scraping member 13 getting stuck on the filter. At the same time, by disposing the extension member 133 inside the cup body 11 and the guiding member 134 outside the cup body 11, the action of the external force on the ash scraping member 13 can be effectively balanced, realizing the smooth operation of the ash scraping member 13.

[0055] Reference Figures 5 - 10, the dust cup assembly 1 further includes a cover body 12. The cover body 12 and the outer periphery of the side wall jointly define a first installation space 14 for installing the guide member 134. The upper baffle 112 and the lower baffle 113 are located in the first installation space 14. The two ends of the guide member 134 are respectively installed on the upper baffle 112 and the lower baffle 113. The two ends of the elastic member 136 respectively abut against the upper baffle 112 and the lower baffle 113. The guide member 134 is arranged inside the elastic member 136. An inwardly extending dust baffle 114 is provided on the inner side of the side wall. A first through hole 115 for the extension member 133 to pass through is provided on the dust baffle 114. The cover body 12, the dust baffle 114 and the inner periphery of the side wall define a second installation space 15. A slit 123 is provided on the side wall of the cup body 11. The connecting member 135 can move along the length direction of the slit 123. The slit 123 communicates the first installation space 14 and the second installation space 15. The second installation space 15 is located above the separation chamber, so that dust entering the second installation space 5 can be effectively reduced. The first installation space 14 is located outside the side wall, and dust entry can also be reduced.

[0056] A second through hole 116 for communicating the first installation space 14 and the external space of the cover body 12 is provided on the cover body 12. A push rod 108 can apply a force to the connecting member 135 through the second through hole 116. Under the action of the force, the connecting member 135 can move along the guide member 134, thereby driving the ash scraping member 13 to move. To achieve the ash scraping action, when the ash scraping member 13 moves to the ash scraping end position ( Figure 11 the position shown), under the action of the elastic member 136, the connecting member 135 drives the ash scraping member 13 to move upward. Finally, the ash scraping member 13 returns to the ash scraping starting position ( Figure 10 the position shown). The push rod 108 can extend outside the housing 102 and be pushed by the user for manual ash scraping. The push rod 108 can also be driven by a driving structure to achieve automatic ash scraping. The driving structure can be powered by a power battery 105.

[0057] Reference Figure 4 , the driving structure can be a driving motor 106. In other embodiments, the driving structure can also be a electromagnetic push rod 108 and other structures. As long as the movement of the push rod 108 can be realized, the movement of the ash scraping member 13 can be realized.

[0058] Reference Figure 4, in one embodiment, the driving structure includes a driving motor 106, a screw structure 107, and a push rod 108 drivingly connected to the screw structure 107. One end of the push rod 108 is drivingly connected to the screw structure 107 by a thread. When the driving motor 106 rotates, the push rod 108 can move to drive the ash scraping member 13 to move from the ash scraping starting position to the ash scraping ending position. When the push rod 108 retracts under the action of the motor, the ash scraping member 13 returns to the ash scraping starting position under the action of the elastic member 136. The driving structure further includes two microswitches to limit the moving range of the push rod 108. When the microswitch is triggered, the driving motor 106 stops operating to avoid stalling of the driving motor 106.

[0059] The dust cup assembly 1 is detachably mounted on the housing 102. To facilitate the installation of the dust cup assembly 1, the housing 102 is further defined with a guiding groove 104, which is adapted to the lid 12 provided on the cup body 11 and configured to guide the installation of the dust cup assembly 1 during the installation of the dust cup assembly 1 onto the housing 102.

[0060] Reference Figure 3 and 14 , when the filter includes a primary filter 121 and a secondary filter 122, the cup body 11 includes a primary ash storage chamber 117 and a secondary ash storage chamber 118. The primary ash storage chamber 117 is located directly below the secondary ash storage chamber 118. The cup body 11 is provided with a first ash discharge port 16, and a first cup lid 161 is used to open and close the first ash discharge port 16; the first ash discharge port 16 is used to empty the dust in the primary ash storage chamber 117. The first ash discharge port 16 is generally provided on the bottom wall of the cup body 11. Of course, it can also be provided on the side wall of the cup body 11. The filter is further provided with a second ash discharge port 17, and a second cup lid 171 is provided at the second ash discharge port 17. The second cup lid 171 is used to open and close the second ash discharge port 17. The second ash discharge port 17 is provided directly above the primary ash storage chamber 117. When the second cup lid 171 is in the open state, the dirt in the secondary ash storage chamber 118 is directly discharged into the primary ash storage chamber 117.

[0061] Reference Figure 24 , the ash scraping member 13 is further provided with an opening structure 18, which is configured to open the second cup lid 171 during the movement of the ash scraping member 13 from the ash scraping starting position to the ash scraping ending position. The opening structure 18 is provided with at least one protrusion, which can contact the second cup lid 171 during the movement to open it.

[0062] Reference Figure 15 and 16, the present application further provides a cleaning system 100. The cleaning system 100 includes a vacuum cleaner 101 and a base station 201. An evacuation fan may be provided on the base station 201. When the vacuum cleaner 101 is docked to the base station 201, the first dust outlet 16 is in an open or openable state. The suction airflow generated by the evacuation fan can keep the first cover 12 in an open state, and at the same time open the second cover 12 to transfer at least part of the dirt in the cup body 11 to the dust bag or recycling bin of the base station 201.

[0063] To save costs, the evacuation fan in the base station 201 can be cancelled, and the airflow generated by the suction motor 103 of the vacuum cleaner 101 is used for evacuation. In this way, an air duct switching component 3 needs to be added between the suction motor 103 and the dust cup assembly 1. The air duct switching component 3 is configured such that when the vacuum cleaner 101 is docked to the base station 201, the channel between the suction motor 103 and the dust cup assembly 1 is cut off, and the suction motor 103 is communicated with the suction channel 21 of the base station 201. The airflow generated by the suction motor 103 can transfer the dirt in the dust cup assembly 1 to the dust bag or recycling bin of the base station 201.

[0064] Reference Figures 16 - 23 , specifically, the air duct switching component 3 includes a body 31 and a switching structure. The body 31 includes an air outlet 35, a first air inlet 33 and a second air inlet 34. The switching structure includes a closing member 36 and a driving member 37. The air outlet 35 is in fluid communication with the suction port of the suction motor 103; the first air inlet 33 can be in fluid communication with the internal space of the dust cup assembly 1, and the second air inlet 34 can be in fluid communication with the dust storage space 22 of the base station 201. The driving member 37 can drive the closing member 36 to close the first air inlet 33 or close the second air inlet 34 under the action of an external force. The closing member 36 is configured to open the second air inlet 34 when closing the first air inlet 33, and open the first air inlet 33 when closing the second air inlet 34. The driving member 37 can be driven by an electric mechanism such as a motor, or can also be manually driven by a user.

[0065] Reference Figures 20 - 23 , in one embodiment, when the vacuum cleaner 101 is docked to the base station 201, the protruding structure 23 on the base station 201 exerts a force on the driving member 37, driving the closing member 36 to move from the position of closing the second air inlet 34 to the position of closing the first air inlet 33. In this way, the direct channel between the suction motor 103 and the dust cup assembly 1 is cut off, and the dirt in the dust cup assembly 1 can only be transferred to the dust storage space 22 of the base station 201 through the suction channel 21 of the base station 201. The driving member 37 includes a first connecting rod 38 and a second connecting rod 39. When the second connecting rod 39 is acted upon by the protruding structure 23, it drives the first connecting rod 38 to move, and the first connecting rod 38 drives the closing member 36 to move.

[0066] The air duct switching assembly 3 further includes a reset member (not shown in the figure), and the reset member is configured to drive the closing member 36 to move from the position of closing the first air inlet 33 to the position of closing the second air inlet 34 when the vacuum cleaner 101 leaves the base station 201, so as to ensure the normal use of the vacuum cleaner 101. The reset member can be a spring structure or other mechanical structures.

[0067] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those familiar with the field, additional modifications can be easily achieved. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated and described examples here.
