Obviously, the described embodiments represent only a portion of the embodiments of this invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of this invention without inventive effort are also protected by this invention.

Figure 1 shows a schematic diagram of the structure of a cleaning device in one or more embodiments of the present invention, Figure 2 shows the cleaning device in Figure 1 in an unlocked state, and Figure 3 shows a schematic diagram of the structure of the sewage tank in Figure 1. In conjunction with Figures 1 to 3, the sewage tank provided by the present invention is assembled on a host computer. The sewage tank includes a housing 2, at least a portion of the outer circumference of the housing 2 being provided with anti-slip grooves 21. When the sewage tank is assembled on the host computer 1, the anti-slip grooves 21 are provided on the exterior of the host computer 1.

In the sewage tank provided by this invention, since at least a portion of the outer peripheral surface of the box body 2 of the sewage tank is provided with anti-slip grooves 21, and the anti-slip grooves 21 are provided on the outside of the host 1, the user can hold the box body 2 with the anti-slip grooves 21 to remove the sewage tank from the host 1, thereby, to a certain extent, avoiding the risk of sewage in the sewage tank falling onto the ground and causing secondary pollution due to the sewage tank falling off during the removal process, and has good practicality.

FIG3 shows a schematic structural diagram of the sewage tank in FIG1 . In conjunction with FIG3 , anti-slip grooves 21 are provided on at least a portion of the outer circumference of the box body 2. The anti-slip grooves 21 are provided on the outer side of the accommodating cavity 11. The user can hold the box body 2 with the anti-slip grooves 21 to remove the sewage tank. This can, to a certain extent, avoid the risk of sewage in the sewage tank falling onto the ground and causing secondary pollution due to the sewage tank falling off during the disassembly process, thus having good practicality.

Referring to Figure 3 , in some embodiments, two anti-slip grooves 21 can be provided, one on each side of the housing 2 in its widthwise direction. The distance between the two anti-slip grooves 21 is approximately the same as the size of a human palm. When removing the sewage tank, the user's thumb applies pressure on one anti-slip groove 21, while the remaining four fingers apply pressure on the other. This means that both primary points of the user's palm apply pressure to the anti-slip grooves 21. This allows the user to hold the housing 2 in the correct position, making it easier for the user to remove the sewage tank from the main unit 1.

In some embodiments, the anti-slip pattern 21 includes a plurality of patterns arranged along the height direction of the box body 2, and the plurality of patterns are arranged in parallel. In other embodiments, the anti-slip pattern 21 can also be arranged only in the middle or end of the outer peripheral surface of the box body 2, etc., which is not limited here.

It should be noted that the anti-slip grooves 21 can be provided on the entire outer circumference of the portion of the housing 2 exposed to the host 1, and this is not limited here.

FIG4 shows a schematic structural diagram of FIG3 from another viewing angle. In conjunction with FIG4 , in some embodiments, the sewage tank further includes a tank cover assembly 3. FIG5 shows a schematic diagram of the tank cover assembly assembled into the tank body. In conjunction with FIG4 and FIG5 , the tank cover assembly 3 is detachably arranged at the inlet and outlet 22 of the tank body 2. The tank cover assembly 3 includes a lid body 31 and a handle 32. The lid body 31 is detachably arranged at the inlet and outlet 22 of the tank body 2. The handle 32 is rotatably connected to the top of the lid body 31. The user can hold the tank cover assembly 3 by the handle 32 and install the tank cover assembly 3 into the tank body 2 from top to bottom.

When cleaning the sewage tank, the lid assembly 3 inside the tank needs to be removed from the tank body 2. In this invention, a handle 32 is provided on the top of the lid body 31. When installing the lid assembly 3 on the sewage tank, the user can use the handle 32 to lift the lid assembly 3 above the inlet/outlet 22 of the tank body 2 (as shown in Figure 5), align the lid assembly 3 with the inlet/outlet 22 of the tank body 2, and then release the handle 32. The lid assembly 3 can then be quickly assembled into the tank body 2 (as shown in Figure 4). At the same time, because the handle 32 is rotatably connected to the lid body 31, after releasing the handle 32, the handle 32 adheres to the upper surface of the lid under the action of gravity (as shown in Figure 4), which does not hinder the assembly of the sewage tank on the host machine 1. When the tank cover assembly 3 needs to be removed from the sewage tank, the user can lift the handle 32 to quickly remove the tank cover assembly 3 from the sewage tank, which is convenient and quick.

Figure 6 shows a schematic diagram of the lid assembly with the handle in a vertical position, and Figure 7 shows the structure of Figure 3 without the filter. In conjunction with Figures 6 and 7, in some embodiments, a mounting frame 4 is provided on the top of the lid 31. This mounting frame 4 has two mounting sidewalls 41 extending along the width of the lid 2. The handle 32 is rotatably connected to the two mounting sidewalls 41 at both ends. In a specific embodiment, the mounting frame 4 is generally U-shaped and can be integrally formed on the top of the lid 31. The handle 32 is connected to the mounting sidewalls 41 on the same side via a pivot.

6 and 7 , in some embodiments, the mounting frame 4 may further include a limiting sidewall 42, which is disposed on the side of the two mounting sidewalls 41 facing away from the interior of the main unit 1. The limiting sidewall has a limiting portion 43 corresponding to the handle 32. The angle between the limiting portion 43 and the upper surface of the partition 6 is less than or equal to 90°, and the handle 32 can rest against the limiting portion 43. When a user holds the lid assembly 3 by the handle 32, the limiting portion 43 limits the handle 32, allowing the handle 32 to remain in an upright position. When the lid assembly 3 is fully assembled, the user releases the handle 32, which can rotate to the top of the lid body 31 under the action of gravity, thereby facilitating the assembly of the sewage tank on the main unit 1.

6 and 7 , in some embodiments, the stopper 43 corresponds to an end of the handle 32, and the end of the handle 32 can rest against the corresponding stopper 43. In other embodiments, the stopper 43 can also correspond to the middle of the handle 32, and the middle of the handle 32 can rest against the corresponding stopper 43, which is not limited here.

6 and 7 , in some embodiments, a guide surface 311 is provided on the top of the lid 31. This guide surface 311 extends downward from the stopper 43 toward the interior of the main unit 1. The angle between the guide surface 311 and the stopper 43 is blunt, and the handle 32 can be pivoted onto the guide surface 311 of the lid 31. Once the tank lid assembly 3 is fully assembled, the user releases the handle 32, which, under the action of gravity, pivots onto the guide surface 311 of the lid 31, facilitating assembly of the sewage tank onto the main unit 1.

Figure 8 shows a schematic diagram of the lid assembly with the handle positioned on the guide surface. In conjunction with Figures 6 to 8, an air outlet duct 33 is provided on the lid body 31, and an induced draft fan is also provided on the cleaning device. When the induced draft fan is operating, air within the sewage tank is drawn out through the air outlet duct 33, creating a negative pressure inside the sewage tank. The sewage sucked up by the cleaning device during operation is then directed into the sewage tank for storage. A filter element 5 is provided in the air outlet duct 33 to prevent air impurities in the sewage tank from entering the induced draft fan and affecting its normal operation. The top of the air outlet duct 33 protrudes from the top of the cover 31. The above-mentioned mounting frame 4 is located on the side of the top of the air outlet duct 33 away from the interior of the main unit 1. The above-mentioned guide surface 311 is located on the side of the top of the air outlet duct 33 facing the interior of the main unit 1. When the sewage tank is assembled with the main unit 1, the handle 32 is also provided on the side of the top of the air outlet duct 33 facing the interior of the main unit 1. The height of the handle 32 is no higher than the height of the top of the air outlet duct 33.

In conjunction with Figures 6 and 8 , in some embodiments, the tank cover assembly 3 further includes a divider 6. Figure 9 illustrates a schematic structural diagram of the divider shown in Figure 8 . In conjunction with Figures 6 , 8 , and 9 , the divider 6 is connected to the bottom of the lid 31 and is provided with a first water leak portion 61. When the tank cover assembly 3 is assembled within the sewage tank, the divider 6 divides the sewage tank into a first chamber located above the divider 6 and a second chamber located below the divider 6. The first and second chambers are connected via the first water leak portion 61.

In the box cover assembly 3 provided by this invention, since the partition 6 is 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 portion 61 to achieve solid-liquid separation.

Referring to Figures 6, 8, and 9, a separator 6 is positioned beneath the lid 31. Separator 6 can be plate-shaped and is located at a mounting hole 62 through which the sewage tank's suction pipe 23 passes. When the sewage tank is in use, sewage within the tank is collected by the suction pipe 23 into the first chamber. Water from the sewage collected in the first chamber is then drained through the first leaking portion 61 into the second chamber, allowing solid waste to be stored in the first chamber. The sewage passes through separator 6 to achieve solid-liquid separation.

Figure 10 shows a schematic top view of Figure 9. In conjunction with Figure 10 , in some embodiments, the first water leakage portion 61 on the separator 6 may include multiple first water leakage holes, which may be arranged in an arc shape around the mounting hole 62. In other embodiments, the multiple first water leakage holes on the separator 6 may also be arranged in a grid pattern, which is not a limitation here.

With reference to Figures 3, 6, and 8 to 10, in some embodiments, the suction pipe 23 is connected to the sidewall of the sewage tank, with the mounting hole 62 opening toward one side of the sidewall to allow the suction pipe 23 to pass through. Specifically, the suction pipe 23 can be integrated into the sidewall of the sewage tank, with a water outlet provided at the top of the suction pipe 23. When the sewage tank is in use, sewage within the sewage tank is collected into the first cavity through the top of the suction pipe 23. Water from the sewage collected in the first cavity is then drained into the second cavity through the first leaking portion 61, allowing solid waste in the sewage to be stored in the first cavity. The sewage passes through the partition 6 to achieve solid-liquid separation. In other embodiments, a water outlet may be provided on the peripheral surface of the water extraction pipe 23 above the partition 6, and the sewage in the sewage tank may be collected into the first cavity, which is not limited here.

With reference to Figures 6 and 8 to 10 , at least a portion of the periphery of the divider 6 elastically abuts the inner wall of the sewage tank to improve the sealing effect between the divider 6 and the inner wall of the sewage tank. In some embodiments, a seal 63 may be provided around the periphery of the divider 6, excluding the opening, so that a slight gap can be provided between the suction pipe 23 and the opening. Of course, the seal 63 may also be provided between the pipe wall of the suction pipe 23 and the opening, which will not be described in detail here. In other embodiments, the periphery of the divider 6 may be elastic, for example, by injection molding a sheet of elastic material around the divider 6. This allows the periphery of the divider 6 to be appropriately compressed when the tank cover assembly 3 is assembled in the sewage tank, thereby improving the sealing effect between the divider 6 and the inner wall of the sewage tank.

Figure 11 shows a schematic structural diagram from another angle of Figure 9. In conjunction with Figures 6 and 8 to 11, the lid assembly 3 further includes a trash baffle 7, which is connected to the divider 6 and disposed within the first cavity, i.e., the trash baffle 7 is connected to the top of the divider 6. The trash baffle 7 is provided with a second water leakage portion 71, and the first water leakage portion 61 is provided on one side of the trash baffle 7. When the lid assembly 3 is removed from the housing 2, the provision of the trash baffle 7 can concentrate the waste in the sewage tank in the area enclosed by the divider 6 and the trash baffle 7, preventing the waste from falling directly onto the ground, preventing secondary contamination, and facilitating waste removal.

With reference to Figures 6 and 8 to 11 , in some embodiments, the trash guard 7 may be connected only to at least a portion of the periphery of the divider 6 . For example, the trash guard 7 is preferably connected to the side of the divider 6 facing away from the main unit 1 , i.e., the trash guard 7 is positioned on the rear side of the divider 6 . In practice, when the user removes the lid assembly 3 from the housing 2 , the sewage tank will face the user, i.e., the sewage tank will be tilted rearward. With the trash guard 7 attached to the rear side of the divider 6 , if sewage is present in the first chamber when the lid assembly 3 is removed, the sewage will flow through the second leak portion 71 of the trash guard 7 to the area behind the trash guard 7 , while the garbage will be stored in the area in front of the divider 6 and the trash guard 7 , making it easier for the user to clean the garbage.

6 and 8 to 11 , in some embodiments, the second water leakage portion 71 may include second water leakage holes arranged in a grid pattern on the garbage baffle 7 to prevent sewage from remaining at the junction of the garbage baffle 7 and the partition 6 , thereby preventing sewage from leaking out of the sewage tank and causing secondary pollution after the box cover assembly 3 is disassembled.

With reference to Figures 6 and 8 to 11 , in some embodiments, a first water leakage portion 61 can be disposed on the front side of the trash baffle 7 to securely separate the first and second cavities formed by the partition 6 . A relief portion 72 is disposed on the side of the trash baffle 7 facing away from the main unit 1 (i.e., the rear side). This relief portion 72 extends toward the interior of the main unit 1 (i.e., the front side) to form a diversion channel. A third water leakage portion 64 is disposed on the partition 6 . At least a portion of the third water leakage portion 64 is disposed within the projection of the relief portion 72 . The third water leakage portion 64 can be a third water leakage hole, disposed directly below the relief portion 72 . When the cleaning device is in use, sewage is present between the trash baffle 7 and the sewage tank. The relief portion 72 and the third water leakage portion 64 are provided to divert sewage into the sewage tank. When the lid assembly 3 is removed, sewage behind the trash baffle 7 can flow into the sewage tank through the avoidance portion 72 and the third leaking portion 64. In other embodiments, a gap can be provided between the trash baffle 7 and the rear wall of the sewage tank body 2, and first leaking portions 61 can be provided on both the front and rear sides of the trash baffle 7. When the lid assembly 3 is removed, sewage behind the trash baffle 7 can flow into the sewage tank through the gap and the third leaking portion 64.

In other embodiments, the trash guard 7 can also be mounted around the top of the divider 6. When the lid assembly 3 is removed, the trash is retained on the divider 6 between the trash guards 7. However, this assembly method requires the lid assembly 3 to be inverted or manually cleaned. Compared to the above-mentioned method in which the trash guard 7 is connected to a portion of the divider 6, trash cleaning is more difficult and is therefore an alternative method.

Referring to Figures 6 and 8 , in some embodiments, the tank cover assembly 3 further includes a flow guide 8 positioned above the mounting hole 62 of the divider 6. When the tank cover assembly 3 is installed in the sewage tank, the flow guide 8 is positioned above the suction pipe 23. When the sewage tank is in use, sewage within the sewage tank is ejected through the top of the suction pipe 23, blocked by the flow guide 8, and then collected in the first chamber.

6 and 8 , in a specific implementation, the guide member 8 may be a U-shaped structure with the opening of the U-shaped structure facing downward, and the side walls of the guide member 8 may be connected to the partition 6 via the bracket 9 .

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.

Referring to Figures 12 to 14 , in some embodiments, a reset member 19 is further provided within the main unit 1 and connected between the main unit 1 and the locking member 10. When the button 12 is pressed, separating the locking member 10 from the sewage tank, the reset member 19 is compressed and deformed. When the button 12 is reset, the reset member 19 returns to its original shape, driving the locking member 10 to reset and lock the sewage tank.

12 to 14 , in a specific implementation, a first connection portion 110 is provided in the host 1, a second connection portion 103 is provided on the locking member 10, and the reset member 19 is connected between the first connection portion 110 and the second connection portion 103 to achieve assembly of the reset member 19 in the host 1.

12 to 14 , in a specific implementation, the first connecting portion 110 and the second connecting portion 103 may both be cylindrical, and the planes in which they are located are offset from the center plane of the channel in which the locking member 10 moves to avoid interfering with the movement of the locking member 10 .

Referring to Figures 5 to 8 and 12 to 13 , in some embodiments, the end of the locking member 10 may be provided with a locking tongue 104. This locking tongue 104 can be inserted into a locking hole 312 in the cover 31 of the sewage tank to lock the sewage tank. The locking tongue 104 has a second mating surface 105 that mates with the sewage tank to drive the locking member 10 away from the sewage tank. When installing the sewage tank on the main unit 1, the user holds the sewage tank and pushes it into the receiving cavity 11 on the main unit 1. The top of the sewage tank body 2 contacts the locking tongue 104 of the locking member 10, driving the locking member 10 upward. After the sewage tank is installed in place, the locking tongue 104 of the locking member 10 is engaged in the locking hole 312 of the sewage tank under the action of the reset member 19 and its own gravity, completing the assembly of the sewage tank on the main unit 1. This is convenient, fast, simple and practical.

In some embodiments, the second mating surface 105 may be a curved surface. In other embodiments, the second mating surface 105 may be a sloped surface.

12 to 14 , in some embodiments, a step 106 may be provided at one end of the locking tongue 104 away from the sewage tank. When the button 12 is pressed or the sewage tank is assembled, the locking member 10 is separated from the sewage tank.
