[0041] Figure 1 , Figure 2 These are, respectively, a three-dimensional half-sectional view and a three-dimensional exploded view of an embodiment of the dust cup assembly of this utility model. The dust cup assembly is detachably connected to the vacuum cleaner main unit. The dust cup assembly includes a first cup body 100 and a cyclone cone assembly 200.

[0042] The cyclone cone assembly 200 is disposed within the first cup body 100. A first cavity K1 is provided between the cyclone cone assembly 200 and the first cup body 100. The cyclone cone assembly 200 has a second cavity K2 inside, and the cyclone cone assembly 200 includes a second cup body 210 and a sealing member 220.

[0043] Figure 3 , Figure 4These are exploded perspective views of the second cup body and the sealing element from different angles in one embodiment of the dust cup assembly of this utility model. The second cup body 210 includes a first opening 211 connecting the first cavity K1 and the second cavity K2, and the second cup body 210 is provided with a slot 2121. The sealing element 220 includes a fixing part 221, a movable part 222, and a connecting part 224. The fixing part 221 is connected to the second cup body 210 through the connecting part 224. The movable part 222 is movable relative to the fixing part 221, and the movable part 222 has a first state of opening the first opening 211 and a second state of sealing the first opening 211.

[0044] Figure 5 This is a three-dimensional half-sectional view of the second cup body and the sealing member in the first state in an embodiment of the dust cup assembly of this utility model. When the movable part 222 is in the first state, it moves to separate from, misalign with or form an angle with the first opening 211, so that the first opening 211 is opened. At this time, the second cavity K2 and the first cavity K1 are connected at the first opening 211. Figure 6 This is a three-dimensional half-sectional view of the second cup body and the sealing member in the second state in one embodiment of the dust cup assembly of this utility model. When the movable part 222 is in the second state, it moves to cover the first opening 211, thereby sealing the first opening 211.

[0045] In this embodiment, the slot 2121 is a stepped slot, meaning that the longitudinal section of the slot 2121 has a stepped dimension change. The connecting part 224 includes an abutting part 2241 and a narrowing part 2242. The narrowing part 2242 connects the abutting part 2241 and the fixing part 221. The width of the narrowing part 2242 is smaller than the width of the abutting part 2241. When the connecting part 224 is installed in the slot 2121, the shapes of the abutting part 2241, the narrowing part 2242 and the stepped slot match, so that the connecting part 224 is engaged in the slot 2121.

[0046] According to an embodiment of the present invention, a dust cup assembly includes a first cup body 100 and a cyclone cone assembly 200. The cyclone cone assembly 200 includes a second cup body 210 and a sealing member 220. A first cavity K1 is formed between the cyclone cone assembly 200 and the first cup body 100, and a second cavity K2 is formed inside the cyclone cone assembly 200. The second cup body 210 includes a first opening 211. The sealing member 220 includes a fixing part 221, a movable part 222, and a connecting part 224. The fixing part 221 is connected to the second cup body 210 through the connecting part 224. The movable part 222 is movable relative to the fixing part 221, wherein the movable part 222 has a first state of opening the first opening 211 and a second state of sealing the first opening 211. When smaller dust particles accumulate inside the cyclone cone assembly 200, these particles are collected in the second cup 210 of the cyclone cone assembly 200. By setting the movable part 222 to the first state, the first opening 211 is opened. At this time, the smaller dust particles accumulated in the second cavity K2 of the cyclone cone assembly 200 can be discharged to the first cavity K1 through the first opening 211, thus cleaning the dust inside the cyclone cone assembly 200 and ensuring that the cyclone cone assembly 200 maintains its high working efficiency. When the dust cup assembly needs to operate normally, the movable part 222 can be set to the second state. At this time, the movable part 222 seals the first opening 211, ensuring the stability of the negative pressure inside the cyclone cone assembly 200 and preventing dust or debris in the first cavity from being sucked into the cyclone cone assembly 200, thereby ensuring the stability of the normal operation of the dust cup assembly.

[0047] According to the dust cup assembly of this embodiment, the second cup body 210 is provided with a slot 2121, and the connecting part 224 includes an abutting part 2241 and a narrowing part 2242. The narrowing part 2242 connects the abutting part 2241 and the fixing part 221, and the width of the narrowing part 2242 is smaller than the width of the abutting part 2241. The shapes of the abutting part 2241, the narrowing part 2242 and the stepped groove are matched so that the connecting part 224 is engaged in the slot 2121, thereby realizing the detachable installation of the sealing member 220 on the second cup body 210. By setting the connecting part 224 and the slot 2121 to a snap-fit ​​engagement, the disassembly and installation of the sealing member 220 and the second cup body 210 can be more convenient. After the connecting part 224 engages with the slot 2121, the abutting part 2241 and the narrowing part 2242 fit the shape of the slot 2121, wherein the abutting part 2241 abuts against the inner wall of the slot 2121, thereby ensuring the stability of the connection between the seal 220 and the second cup body 210.

[0048] like Figure 5 When the dust cup assembly is not in operation, the movable part 222 swings away from the fixed part 221 in a direction away from the second cavity K2, so that the movable part 222 is in the first state.

[0049] like Figure 6When the dust cup assembly is in working condition, the second cavity K2 has negative pressure and generates suction force on the movable part 222, so that the movable part 222 is in the second state.

[0050] The dust cup assembly is used in the cleaning device and connects to the vacuum cleaner main unit. When the cleaning device is in operation, the dust cup assembly is also in operation. The normal operation of the vacuum cleaner main unit creates negative pressure in the second chamber K2 of the cyclone cone assembly 200. This negative pressure in the second chamber K2 generates suction on the movable part 222. The movable part 222 is in a second state, that is, it seals the first opening 211, ensuring the stability of the negative pressure within the cyclone cone assembly 200 and preventing dust or debris from the first chamber from being sucked into the cyclone cone assembly 200.

[0051] In some embodiments, the non-working state of the dust cup assembly includes an idle state. Optionally, in the idle state, the movable part 222 can swing relative to the fixed part 221 away from the second cavity K2 under its own gravity. At this time, the movable part 222 is in a first state, and the smaller dust particles accumulated in the second cavity K2 of the cyclone cone assembly 200 can be discharged to the first cavity K1 through the first opening 211.

[0052] In some embodiments, the non-operating state of the dust cup assembly includes a base station maintenance state. Specifically, the dust cup assembly is used in a cleaning device and connected to the vacuum cleaner host. The cleaning device may also include a base station, and the vacuum cleaner host can be connected to the base station. When the cleaning device enters the base station maintenance state, the base station docks with the dust cup assembly, allowing the base station dust collection assembly inside the base station to communicate with the first cavity K1 of the dust cup assembly. The base station dust collection assembly generates negative pressure to suck up the dust and debris in the first cavity K1. At this time, under the negative pressure of the first cavity K1, the movable part 222 swings relative to the fixed part 221 away from the second cavity K2. The movable part 222 is in the first state, and the smaller dust particles accumulated in the second cavity K2 of the cyclone cone assembly 200 can be discharged to the first cavity K1 through the first opening 211, thereby being collected by the base station dust collection assembly along with the original dust and debris in the first cavity K1.

[0053] like Figure 3 , Figure 4 In some embodiments, the movable part 222 and the fixed part 221 are a flexible component with an integral structure. In this case, the movement of the movable part 222 relative to the fixed part 221 is the deformation movement of the movable part 222 relative to the fixed part 221. In this embodiment, the movable part 222 and the fixed part 221 are an integral structure, reducing the problem of poor sealing caused by the splicing of the movable part 222 and the fixed part 221. The movable part 222 is a flexible component, which ensures that the movable part 222 can move relative to the fixed part 221.

[0054] In some embodiments, the movable part 222, the fixed part 221, and the connecting part 224 are an integral structure. Since the connecting part 224 and the fixed part 221 are also an integral structure, the seal 220 and the second cup 210 no longer require additional connecting parts, improving the convenience of disassembly and installation between the seal 220 and the second cup 210.

[0055] In some embodiments, the connecting portion 224 extends parallel to the swing axis of the movable portion 222 relative to the fixed portion 221.

[0056] like Figure 3 , Figure 4 In some embodiments, the second cup body 210 is provided with an installation opening 213, which is located on the side wall of the second cup body 210 and communicates with the slot 2121. The connecting part 224 can be inserted into or removed from the slot 2121 through the installation opening 213. By providing an installation opening 213 on the second cup body 210, the convenience of assembly and disassembly between the seal 220 and the second cup bottom 212 is further improved.

[0057] like Figures 3 to 6 In some embodiments, the seal 220 includes a first groove 223 disposed at the connection between the movable part 222 and the fixed part 221. The first groove 223 is located on the surface of the seal 220 away from the second cavity K2 and extends parallel to the swing axis of the movable part 222 relative to the fixed part 221.

[0058] Since a first groove 223 is provided on the surface of the seal 220 away from the second cavity K2, when the movable part switches from the second state to the first state, the movable part 222 swings away from the second cavity K2 relative to the fixed part 221. At this time, the first groove 223 can provide clearance for the swinging movement of the movable part 222, ensuring that the movable part 222 can smoothly switch to the first state, and to a certain extent improve the movement angle of the movable part 222 in the first state, thereby improving the opening degree of the first opening 211, so that the smaller dust particles accumulated in the second cavity K2 can fall into the first cavity K1.

[0059] In the above embodiments, the movable part 222 and the fixed part 221 are a flexible component with an integral structure, enabling the movable part 222 to move relative to the fixed part 221. In other embodiments, the movement of the movable part 222 relative to the fixed part 221 can be achieved in other ways. For example, in other embodiments, the seal 220 further includes a rotating shaft connector that rotatably connects the movable part 222 and the fixed part 221.

[0060] Figure 7This is an exploded half-sectional view of the second cup body and the sealing element in one embodiment of the dust cup assembly of this utility model. In some embodiments, the second cup body 210 has a second cup bottom 212, a first opening 211 and a slot 2121 disposed on the second cup bottom 212, and the second cup bottom 212 is provided with a limiting protrusion 2122, which is located on the side of the slot 2121 away from the first opening 211.

[0061] In some embodiments, the fixing part 221 is provided with a limiting hole 2211, the connecting part 224 is engaged in the slot 2121, and the limiting hole 2211 and the limiting protrusion 2122 are connected by an interference fit, so that the fixing part 221 is fixedly connected to the second cup body 210.

[0062] In the above embodiments, by providing a connecting part 224 and a limiting hole 2211 on the sealing member 220, and providing a slot 2121 that cooperates with the connecting part 224 and a limiting protrusion 2122 that cooperates with the limiting hole 2211 on the bottom of the second cup 212, a stable connection between the fixing part 221 and the second cup body 210 can be ensured.

[0063] like Figures 5 to 7 In some embodiments, the second cup body 210 has a second cup bottom 212, and a first opening 211 is disposed on the second cup bottom 212. At least part of the surface of the second cup bottom 212 facing the second cavity K2 is a second inclined surface 2123. The second inclined surface 2123 is inclined relative to the plane where the first opening 211 is located. The second inclined surface 2123 is configured to guide the material on the second inclined surface 2123 toward the direction of the first opening 211, so that the smaller dust particles accumulated in the second cavity K2 can be discharged outward through the first opening 211.

[0064] In some embodiments, a portion of the surface of the second cup bottom 212 facing the second cavity K2 is a second slope 2123. In some embodiments, the entire continuous surface of the second cup bottom 212 facing the second cavity K2 is the second slope 2123.

[0065] like Figure 1 , Figure 2In some embodiments, the cyclone cone assembly 200 further includes a cyclone cone support 230, a cyclone cone 240, and a filter screen 250, wherein there may be multiple cyclone cones 240. The cyclone cone 240 and the filter screen 250 are mounted on the cyclone cone support 230, with the filter screen 250 surrounding the outer periphery of the cyclone cone 240, wherein the outer periphery of the filter screen 250 is aligned with the outer periphery of the second cup 210. In this embodiment, the bottom of the filter screen 250 abuts against the top of the second cup 210, and the outer periphery of the filter screen 250 and the outer periphery of the second cup 210 are aligned at their abutment. Because the outer periphery of the filter screen 250 is aligned with the outer periphery of the second cup 210, the stepped structure at the abutment of the filter screen 250 and the second cup 210 is eliminated, which can prevent longer pieces of trash (such as hair, long strips of paper, lines, etc.) from getting caught on the filter screen 250 to a certain extent.

[0066] like Figure 2 In some embodiments, the first cup body 100 has a first cup bottom 110 and an air inlet 120.

[0067] Figure 8 This is a three-dimensional schematic diagram of the cyclone cone bracket in one embodiment of the dust cup assembly of this utility model. Figure 2 , Figure 8 In some embodiments, the cyclone cone support 230 includes a support body 231 and an air guide 232 connected to the support body 231. The air guide 232 is exposed outside the filter screen 250 and is opposite to the air inlet 120. The air guide 232 includes an air guide plate 2321 that protrudes toward the air inlet 120. The air guide plate 2321 is located on the side of the air inlet 120 facing the first cup bottom 110 and extends circumferentially along the filter screen 250.

[0068] In the above embodiment, the air guide 232 is opposite to the air inlet 120. When the dust cup assembly is in working condition, the external airflow (mixed with dust or garbage) enters the first cavity K1 of the dust cup assembly through the air inlet 120. At this time, the air guide 232 guides the airflow (mixed with dust or garbage) entering from the air inlet 120 to flow along the circumference of the filter screen 250, thereby improving the working efficiency of the cyclone cone assembly 200 and reducing the disturbance of the airflow to the dust already collected in the first cavity K1 to a certain extent.

[0069] like Figure 2 In some embodiments, the dust cup assembly further includes a filter mounting bracket 300 and a dust cup filter 400, the filter mounting bracket 300 being connected to the cyclone cone assembly 200, and the dust cup filter 400 being mounted on the filter mounting bracket 300. In some embodiments, the filter mounting bracket 300 is disposed on the side of the cyclone cone support 230 opposite to the second cup body 210. The dust cup filter 400 is, for example, a HEPA filter.

[0070] like Figure 2 In some embodiments, the first cup body 100 has a first cup bottom 110, the first cup bottom 110 is provided with a second opening 111, and the surface of the first cup bottom 110 facing the first cavity K1 is at least partly a first inclined surface 112. The first inclined surface 112 is inclined relative to the plane where the second opening 111 is located. The first inclined surface 112 is configured to guide the material on the first inclined surface 112 toward the direction of the second opening 111, so that the dust or garbage accumulated in the first cavity K1 can be discharged outward through the second opening 111.

[0071] like Figure 2 In some embodiments, the first cup body 100 has a first cup bottom 110 and a first side wall 130, and the first cup body 100 includes a dustproof member 140 erected on the first cup bottom 110 and connected to the first side wall 130.

The connecting part 224 includes an abutting part 2241 and a narrowing part 2242. The narrowing part 2242 is connected between the abutting part 2241 and the fixing part 221. The width of the narrowing part 2242 is smaller than the width of the abutting part 2241. When the connecting part 224 is installed in the slot 2121, the shapes of the abutting part 2241, the narrowing part 2242 and the stepped groove match, so that the connecting part 224 is engaged in the slot 2121.

[0076] The cleaning device according to an embodiment of the present invention includes a dust cup assembly, which includes a first cup body 100 and a cyclone cone assembly 200. The cyclone cone assembly 200 includes a second cup body 210 and a sealing member 220. A first cavity K1 is formed between the cyclone cone assembly 200 and the first cup body 100, and a second cavity K2 is formed inside the cyclone cone assembly 200. The second cup body 210 includes a first opening 211, and the sealing member 220 includes a fixing part 221, a movable part 222, and a connecting part 224. The fixing part 221 is connected to the second cup body 210 through the connecting part 224, and the movable part 222 is movable relative to the fixing part 221. The movable part 222 has a first state of opening the first opening 211 and a second state of sealing the first opening 211. When smaller dust particles accumulate inside the cyclone cone assembly 200, these particles are collected in the second cup 210 of the cyclone cone assembly 200. By setting the movable part 222 to the first state, the first opening 211 is opened. At this time, the smaller dust particles accumulated in the second cavity K2 of the cyclone cone assembly 200 can be discharged to the first cavity K1 through the first opening 211, thus cleaning the dust inside the cyclone cone assembly 200 and ensuring that the cyclone cone assembly 200 maintains its high working efficiency. When the dust cup assembly needs to operate normally, the movable part 222 can be set to the second state. At this time, the movable part 222 seals the first opening 211, ensuring the stability of the negative pressure inside the cyclone cone assembly 200 and preventing dust or debris in the first cavity from being sucked into the cyclone cone assembly 200, thereby ensuring the stability of the normal operation of the dust cup assembly.

[0077] According to the cleaning device of this utility model embodiment, in the dust cup assembly, the second cup body 210 is provided with a slot 2121, and the connecting part 224 includes an abutting part 2241 and a narrowing part 2242. The narrowing part 2242 connects the abutting part 2241 and the fixing part 221, and the width of the narrowing part 2242 is smaller than the width of the abutting part 2241. The shapes of the abutting part 2241, the narrowing part 2242 and the stepped groove are matched so that the connecting part 224 is engaged in the slot 2121, thereby realizing the detachable installation of the sealing member 220 on the second cup body 210. By setting the connecting part 224 and the slot 2121 to a snap-fit ​​engagement, the disassembly and installation of the sealing member 220 and the second cup body 210 can be more convenient. After the connecting part 224 engages with the slot 2121, the abutting part 2241 and the narrowing part 2242 fit the shape of the slot 2121, wherein the abutting part 2241 abuts against the inner wall of the slot 2121, thereby ensuring the stability of the connection between the seal 220 and the second cup body 210.
