When it is necessary to remove the box cover assembly 3 from the sewage tank, the user can quickly remove the box cover assembly 3 from the sewage tank by holding the handle 32, which is convenient and quick, thereby improving the efficiency of disassembly and assembly of the box assembly on the sewage tank and improving the user experience.

[0052] Figure 6 The schematic diagram of the structure of the box cover assembly with the handle in a vertical state is shown. Figure 7 Shows Figure 3 Schematic diagram of the structure of removing the filter element. Figure 6 as well as Figure 7 In some embodiments, a mounting frame 4 is disposed on the top of the cover 31, and the mounting frame 4 has two mounting side walls 41 disposed along the width direction of the box 2, and both ends of the handle 32 are rotatably connected to the two mounting side walls 41. In a specific implementation, the mounting frame 4 is generally U-shaped, and it can be integrally formed on the top of the cover 31, and both ends of the handle 32 can be connected to the mounting side walls 41 on the same side through a rotating shaft.

[0053] Combination Figure 6 as well as Figure 7 In some embodiments, the mounting frame 4 may further include a limiting side wall 42, which is connected to the side of the two mounting side walls 41 facing away from the inside of the host 1, and has a limiting portion 421 corresponding to the handle 32, and the handle 32 may lean against the limiting portion 421. When the user holds the case cover assembly 3 by the handle 32, the limiting portion 421 limits the position of the handle 32, so that the handle 32 can be kept in a vertical state.

[0054] Combination Figure 6 as well as Figure 7 In some embodiments, the angle between the limit portion 421 and the horizontal plane extending from the cover body 31 to the inside of the main unit 1 is less than or equal to 90°. When the box cover assembly 3 is assembled in place, the user releases the handle 32, and the handle 32 can be rotated to the top of the cover body 31 under the operation of gravity to facilitate the assembly of the sewage tank on the main unit 1.

[0055] Combination Figure 6 as well as Figure 7 In some embodiments, the limiting portion 421 corresponds to the end of the handle 32, and the end of the handle 32 can be pressed against the corresponding limiting portion 421. In other embodiments, the limiting portion 421 can also correspond to the middle of the handle 32, and the middle of the handle 32 can be pressed against the corresponding limiting portion 421, which is not limited here.

[0056] Combination Figure 6 as well as Figure 7In some embodiments, a guide surface 311 is provided on the top of the cover body 31, and the guide surface 311 extends downward from the stop portion 421 toward the inside of the host 1, and the angle between the guide surface 311 and the stop portion 421 is an obtuse angle, and the handle 32 can be rotated to the guide surface 311 of the cover body 31. When the tank cover assembly 3 is assembled in place, the user releases the handle 32, and the handle 32 can be rotated to the guide surface 311 of the cover body 31 under the operation of gravity, so as to facilitate the assembly of the sewage tank on the host 1.

[0057] Figure 8 The schematic diagram of the structure of the box cover assembly with the handle on the guide surface is shown. Figure 6-Figure 8 , an air outlet channel 33 is also provided on the cover body 31, and an induced draft fan is also provided on the cleaning device. When the induced draft fan is working, the air in the sewage tank is led out through the air outlet channel 33, so that a negative pressure is formed inside the sewage tank, and the sewage sucked by the cleaning device when working is led into the sewage tank for storage. A filter 5 is provided in the air outlet channel 33 to prevent air impurities in the sewage tank from entering the induced draft fan and affecting the normal operation of the induced draft fan. The top of the air outlet channel 33 protrudes from the top of the cover body 31, and the above-mentioned mounting frame 4 is located on the side of the top of the air outlet channel 33 away from the inside of the main unit 1, and the above-mentioned guide surface 311 is located on the side of the top of the air outlet channel 33 facing the inside of the main unit 1. When the sewage tank is assembled on the main unit 1, the handle 32 is also laid on the side of the top of the air outlet channel 33 facing the inside of the main unit 1, and the height of the handle 32 is not higher than the height of the top of the air outlet channel 33.

[0058] Combination Figure 6 as well as Figure 8 In some embodiments, the box cover assembly 3 also includes a partition 6. Fig. 9 Shows Figure 8 Schematic diagram of the structure of the separator, combined with Figure 6 , Figure 8 as well as Fig. 9 , the partition 6 is connected to the bottom of the cover body 31, and a first water leakage part 61 is provided on the partition 6; wherein, when the box cover assembly 3 is assembled in the sewage tank, the partition 6 divides the sewage tank into a first cavity located above the partition 6 and a second cavity located below the partition 6, and the first cavity and the second cavity are connected through the first water leakage part 61.

[0059] The box cover assembly 3 provided in the present application has a partition 6 connected to the bottom of the cover body 31. When the box cover assembly 3 is assembled in the sewage tank, the partition 6 divides the sewage tank into a first cavity located above the partition 6 and a second cavity located below the partition 6. After the sewage sucked into the sewage tank together with the solid waste is sucked into the first cavity, the sewage flows into the second cavity through the first leaking part 61 to achieve solid-liquid separation.

[0060] Combination Figure 6 , Figure 8 as well as Fig. 9 The partition 6 is arranged below the cover 31. The partition 6 may be in the shape of a plate. The partition 6 is arranged at a mounting hole 62 through which the suction pipe 23 of the sewage tank passes. When the sewage tank is used, the sewage in the sewage tank is collected into the first cavity through the suction pipe 23. The water in the sewage collected into the first cavity is drained into the second cavity through the first leaking portion 61, so that the solid waste in the sewage is stored in the first cavity. The sewage is separated into solid and liquid through the partition 6.

[0061] Fig.10 Shows Fig. 9 Schematic diagram of top view. Fig.10 In some embodiments, the first water leakage portion 61 on the partition 6 may include a plurality of first water leakage holes, and the plurality of first water leakage holes may be arranged in an arc shape around the mounting hole 62. In other embodiments, the plurality of first water leakage holes on the partition 6 may also be arranged in a grid shape, which is not limited here.

[0062] Combination Figure 3 , combined Figure 6 as well as Figure 8-Figure 10 In some embodiments, the water pumping pipe 23 is connected to the side wall of the sewage tank, and the mounting hole 62 is open toward one side of the side wall for the water pumping pipe 23 to pass through. In specific implementation, the water pumping pipe 23 can be integrated into the side wall of the sewage tank, and a water outlet is provided at the top of the water pumping pipe 23. When the sewage tank is used, the sewage in the sewage tank is collected into the first cavity through the top of the water pumping pipe 23, and the water in the sewage collected into the first cavity is drained into the second cavity through the first water leakage part 61, so that the solid waste in the sewage is stored in the first cavity, and the sewage is separated into solid and liquid through the partition 6. In other embodiments, a water outlet can also be provided on the peripheral surface of the water pumping pipe 23 above the partition 6, and the sewage in the sewage tank can also be collected into the first cavity, which is not limited here.

[0063] Combination Figure 6 as well as Figure 8-Figure 10 , at least part of the periphery of the partition 6 is elastically abutted against the inner wall of the sewage tank to improve the sealing effect between the partition 6 and the inner wall of the sewage tank. In some embodiments, a seal 63 can be provided at the periphery of the partition 6 except for the opening, and the suction pipe 23 and the opening can be matched with a small gap. Of course, the seal 63 can also be provided between the pipe wall and the opening of the suction pipe 23, which will not be described in detail here. In other embodiments, the periphery of the partition 6 can be elastic, for example, a plate of elastic material is injection molded at the periphery of the partition 6, so that when the box cover assembly 3 is assembled in the sewage tank, the periphery of the partition 6 can be appropriately compressed to improve the sealing effect between the partition 6 and the inner wall of the sewage tank.

[0064] Fig.11 Shows Fig. 9 Another structural diagram of the perspective. Figure 6 as well as Figure 8-Figure 11 The box cover assembly 3 may further include a garbage baffle 7, which is connected to the partition 6 and is disposed in the first cavity, that is, the garbage baffle 7 is connected to the top of the partition 6, and a second water leakage portion 71 is disposed on the garbage baffle 7, and the first water leakage portion 61 is disposed on one side of the garbage baffle 7. When the box cover assembly 3 is disassembled from the box body 2, the setting of the garbage baffle 7 can concentrate the garbage in the sewage tank on the area surrounded by the partition 6 and the garbage baffle 7, so as to prevent the garbage from falling directly on the ground, avoid secondary pollution, and facilitate the cleaning of the garbage.

[0065] Combination Figure 6 as well as Figure 8-Figure 11 In some embodiments, the garbage baffle 7 may be connected only to at least a portion of the periphery of the partition 6. For example, the garbage baffle 7 is preferably connected to the side of the partition 6 away from the main unit 1, that is, the garbage baffle 7 is arranged on the rear side of the partition 6. In actual implementation, when the user removes the box cover assembly 3 from the box body 2, the sewage tank will face the user, that is, the sewage tank will tilt to the rear side. Under the condition that the garbage baffle 7 is connected to the rear side of the partition 6, when the box cover assembly 3 is removed, if there is sewage in the first cavity, the sewage will flow to the area behind the garbage baffle 7 through the second water leakage part 71 on the garbage baffle 7, and the garbage will be stored in the area in front of the partition 6 and the garbage baffle 7, so that the user can clean the garbage conveniently.

[0066] Combination Figure 6 as well as Figure 8-Figure 11 In some embodiments, the second water leakage portion 71 may include a second water leakage hole arranged in a grid shape on the garbage baffle 7 to prevent sewage from remaining at the junction of the garbage baffle 7 and the partition 6, so as to avoid leakage outside the sewage tank and causing secondary pollution after the box cover assembly 3 is disassembled.

[0067] Combination Figure 6 as well as Figure 8-Figure 11In some embodiments, the first water leakage part 61 can be arranged at the front side of the garbage baffle 7 to be used for the fixed separation of the first cavity and the second cavity of the partition 6. A avoidance part 72 is arranged on the side of the garbage baffle 7 away from the host 1 (i.e., the rear side), and the avoidance part 72 extends toward the inside of the host 1 (i.e., the front side) to form a guide groove. A third water leakage part 64 is arranged on the partition 6, and at least part of the third water leakage part 64 is arranged in the projection of the avoidance part 72. The third water leakage part 64 can be a third water leakage hole, which is arranged directly below the avoidance part 72. When the cleaning device is in use, there is sewage between the garbage baffle 7 and the sewage tank. The avoidance part 72 and the third water leakage part 64 are arranged to allow the sewage to flow into the sewage tank, which plays a diversion role. When the box cover assembly 3 is disassembled, the sewage located at the rear side of the garbage baffle 7 can flow into the sewage tank through the avoidance part 72 and the third water leakage part 64. In other embodiments, there may be a gap between the garbage baffle 7 and the rear side wall of the box body 2 of the sewage tank, and the front and rear sides of the garbage baffle 7 are both provided with a first water leakage portion 61. When the box cover assembly 3 is removed, the sewage flow located on the rear side of the garbage baffle 7 can flow into the sewage tank through the above-mentioned gap and the third water leakage portion 64.

[0068] In other embodiments, the garbage baffle 7 can also be arranged around the top of the partition 6, and when the box cover assembly 3 is disassembled, the garbage is retained on the partition 6 between the garbage baffles 7. However, this assembly method can only be used to clean the garbage by inverting the box cover assembly 3 or manually cleaning. Compared with the above-mentioned solution in which the garbage baffle 7 is connected to part of the periphery of the partition 6, it is more difficult to clean the garbage, which is an optional solution.

[0069] Combination Figure 6 as well as Figure 8 In some embodiments, the tank cover assembly 3 further includes a flow guide 8, which is disposed above the mounting hole 62 of the partition 6. When the tank cover assembly 3 is assembled in the sewage tank, the flow guide 8 is disposed above the water suction pipe 23. When the sewage tank is used, the sewage in the sewage tank is sprayed out through the top of the water suction pipe 23, and after being blocked by the flow guide 8, it is collected in the first cavity.

[0070] Combination Figure 6 as well as Figure 8 In a specific implementation, the guide member 8 can be a U-shaped structure, the opening of the U-shaped structure of the guide member 8 faces downward, and the side walls on both sides of the guide member 8 can be connected to the partition 6 through the bracket 9.

[0071] In some embodiments, a sealing plate 81 may be provided on the rear side of the guide member 8 so that the guide groove forms a cover structure with a bottom and a front opening.

[0072] In conjunction with the figure, in some embodiments, the cover body 31 can be integrally formed on the top of the guide member 8, and an air inlet 34 is provided on the side wall of the cover body 31. The air inlet 34 is provided above the guide member 8, and the air inlet 34 is the entrance of the air inlet channel to draw out the air in the sewage tank.

[0073] Based on the above-mentioned sewage tank, the present application also provides a cleaning device, which includes a main unit 1 and the above-mentioned sewage tank, and the above-mentioned sewage tank is detachably mounted on the main unit 1.

[0074] When cleaning the sewage tank, the cleaning device provided in the present application needs to remove the box cover assembly 3 in the sewage tank from the box body 2 of the sewage tank. Since the present application provides a handle 32 on the top of the cover body 31, when installing the box cover assembly 3 on the sewage tank, the user can lift the box cover assembly 3 to the top of the inlet and outlet 22 of the box body 2 of the sewage tank by the handle 32 ( Figure 5 As shown), the box cover assembly 3 is aligned with the inlet and outlet 22 of the box body 2, and then the handle 32 is released, and the box cover assembly 3 can be quickly assembled in the box body 2 ( Figure 4 As shown), at the same time, since the handle 32 is rotatably connected to the cover body 31, after the handle 32 is released, the handle 32 is attached to the upper surface of the box cover under the action of gravity ( Figure 4 As shown), it does not hinder the assembly of the sewage tank on the host 1.
