DETAILED DESCRIPTION

[0058] In order to enable those skilled in the art to understand the present disclosure more clearly, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present disclosure.

[0059] Figure 1 is a schematic diagram of the structure of a cleaning device according to some embodiments of the present disclosure, Figure 2 is a schematic diagram of the cleaning device in Figure 1 in an unlocked state, and Figure 3 is a schematic diagram of the structure of the water tank in Figure 1. In conjunction with Figures 1-3, a water tank according to some embodiments of the present disclosure is assembled on a main unit 1-1, and includes a housing 12-b1. Anti-slip grooves 1-21 are provided on at least a portion of the outer circumference of the housing 12-b1. When the water tank is assembled on the main unit 1-1, the anti-slip grooves 1-21 are provided on the exterior of the main unit 1-1.

[0060] In some embodiments, the water tank may include a dirty water tank or a clean water tank.

[0061] According to some embodiments of the water tank disclosed herein, since at least a portion of the outer peripheral surface of the box body 12-b1 of the water tank is provided with anti-slip grooves 1-21, and the anti-slip grooves 1-21 are provided on the outside of the main unit 1-1, the user can hold the box body 12-b1 with the anti-slip grooves 1-21 to remove the water tank from the main unit 1-1, thereby avoiding to a certain extent the risk of the water tank falling off during the disassembly process, causing the sewage in the water tank to spill onto the ground and cause secondary pollution, and has good practicality.

[0062] Figure 3 shows a schematic structural diagram of the water tank in Figure 1. In combination with Figure 3, anti-slip grooves 1-21 are provided on at least part of the outer peripheral surface of the box body 12-b1. The anti-slip grooves 1-21 are provided on the outside of the accommodating cavity 1-11. The user can hold the box body 12-b1 with the anti-slip grooves 1-21 to disassemble the water tank, thereby avoiding to a certain extent the risk of the water tank falling off during the disassembly process, causing the sewage in the water tank to spill onto the ground and cause secondary pollution, and has good practicality.

[0063] In conjunction with FIG3 , in some embodiments, two anti-slip grooves 1-21 may be provided, one on each side of the width of the housing 12-b1. The circumference between the two anti-slip grooves 1-21 is approximately the same as the palm of a human hand. When a user removes the water tank, the user's thumb applies pressure on one anti-slip groove 1-21, while the user's other four fingers apply pressure on the other anti-slip groove 1-21. That is, the two main points of force of the user's palm apply pressure on the anti-slip grooves 1-21. This adapts to the user's holding posture of the housing 12-b1 and makes it easier for the user to remove the water tank from the main unit 1-1.

[0064] In some embodiments, the anti-slip pattern 1-21 includes multiple patterns arranged along the height direction of the box body 12-b1, and the multiple patterns are arranged in parallel. In other embodiments, the anti-slip pattern 1-21 can also be provided only in the middle or end of the outer peripheral surface of the box body 12-b1, etc., without limitation.

[0065] It should be noted that the anti-slip grooves 1-21 can be provided on the entire outer peripheral surface of the portion of the box body 12-b1 exposed to the host 1-1, and there is no limitation here.

[0066] FIG4 shows a schematic structural diagram of the water tank in FIG3 from another perspective. In conjunction with FIG4 , in some embodiments, the water tank further includes a tank cover assembly 12-3. FIG5 shows a schematic diagram of the state in which the tank cover assembly 12-3 of the water tank according to some embodiments of the present disclosure is assembled into the tank body 12-b1. In conjunction with FIG4 and FIG5 , the tank cover assembly 12-3 is detachably arranged at the inlet and outlet 12-b2 of the tank body 12-b1. The tank cover assembly 12-3 includes a cover body 1-31 and a handle 1-32. The cover body 1-31 is detachably arranged at the inlet and outlet 12-b2 of the tank body 12-b1. The handle 1-32 is rotatably connected to the top of the cover body 1-31. The user can hold the tank cover assembly 12-3 by the handle 1-32 and install the tank cover assembly 12-3 into the tank body 12-b1 from top to bottom.

[0067] When cleaning the water tank, it is necessary to remove the tank cover assembly 12-3 from the tank body 12-b1. In some embodiments, since a handle 1-32 is provided on the top of the cover body 1-31, when installing the tank cover assembly 12-3 on the water tank, the user can use the handle 1-32 to lift the tank cover assembly 12-3 to the top of the inlet and outlet 12-b2 of the tank body 12-b1 (as shown in FIG5), so as to align the tank cover assembly 12-3 with the inlet and outlet 12-b2 of the tank body 12-b1, and then release the handle 1-32. The tank cover assembly 12-3 can be quickly assembled in the tank body 12-b1 (as shown in FIG4). Moreover, since the handle 1-32 is rotatably connected to the cover body 1-31, after releasing the handle 1-32, the handle 1-32 is attached to the upper surface of the tank cover under the action of gravity (as shown in FIG4), and does not hinder the assembly of the water tank on the host 1-1. Therefore, when it is necessary to remove the tank cover assembly 12-3 from the water tank, the user can quickly remove the tank cover assembly 12-3 from the water tank by carrying the handle 1-32, which is convenient and quick.

[0068] FIG6 shows a schematic structural diagram of the tank cover assembly 12-3 with the handle 1-32 in a vertical position in a water tank according to some embodiments of the present disclosure, and FIG7 shows a schematic structural diagram of the water tank in FIG3 with the filter element 1-5 removed. In conjunction with FIG6 and FIG7, in some embodiments, a mounting frame 1-4 is provided on the top of the cover body 1-31, and the mounting frame 1-4 has two mounting side walls 1-41 provided along the width direction of the tank body 12-b1, and the two ends of the handle 1-32 are rotatably connected to the two mounting side walls 1-41. In some embodiments, the mounting frame 1-4 is roughly U-shaped and can be integrally formed on the top of the cover body 1-31, and the two ends of the handle 1-32 can be connected to the mounting side walls 1-41 on the same side through a rotating shaft.

[0069] In conjunction with Figures 6 and 7, in some embodiments, the mounting frame 1-4 may further include a limiting sidewall 1-42. The limiting sidewall 1-42 is connected to the side of the two mounting sidewalls 1-41 facing away from the interior of the main unit 1-1. The limiting sidearm has a limiting portion 1-421 corresponding to the handle 1-32. The angle between the limiting portion 1-421 and the horizontal plane extending from the cover 1-31 toward the interior of the main unit 1-1 is less than or equal to 90°. The handle 1-32 can rest against the limiting portion 1-421. When a user holds the lid assembly 12-3 by the handle 1-32, the limiting portion 1-421 holds the handle 1-32 in an upright position. Once the lid assembly 12-3 is fully assembled, the user releases the handle 1-32, and the handle 1-32 rotates to the top of the cover 1-31 under the force of gravity, facilitating assembly of the water tank onto the main unit 1-1.

[0070] 6 and 7 , in some embodiments, the limiting portion 1-421 corresponds to an end of the handle 1-32, and the end of the handle 1-32 can abut against the corresponding limiting portion 1-421. In other embodiments, the limiting portion 1-421 can also correspond to the middle of the handle 1-32, and the middle of the handle 1-32 can abut against the corresponding limiting portion 1-421. This is not a limitation.

[0071] In conjunction with Figures 6 and 7, in some embodiments, a guide surface 1-311 is provided on the top of the cover body 1-31, and the guide surface 1-311 extends downward from the limiting portion 1-421 toward the interior of the main unit 1-1. The angle between the guide surface 1-311 and the limiting portion 1-421 is an obtuse angle. The handle 1-32 can be rotated onto the guide surface 1-311 of the cover body 1-31. When the tank cover assembly 12-3 is assembled in place, the user releases the handle 1-32, and the handle 1-32 can be rotated onto the guide surface 1-311 of the cover body 1-31 under the operation of gravity to facilitate the assembly of the water tank on the main unit 1-1.

[0072] Figure 8 shows a schematic structural diagram of a tank cover assembly 12-3 in which the handle 1-32 of the water tank is located on a guide surface 1-311 according to some embodiments of the present disclosure. In conjunction with Figures 6 to 8, an air outlet channel 1-33 is also provided on the cover body 1-31, and an induced draft fan is also provided on the cleaning device. When the induced draft fan is working, the air in the water tank is drawn out through the air outlet channel 1-33, forming a negative pressure inside the water tank. The sewage sucked in by the cleaning device when working is then drained into the water tank for storage. A filter element 1-5 is provided in the air outlet channel 1-33 to prevent air impurities in the water tank from entering the induced draft fan and affecting the normal operation of the induced draft fan. The top of the air outlet channel 1-33 protrudes from the top of the cover body 1-31. The above-mentioned mounting frame 1-4 is located on the side of the top of the air outlet channel 1-33 away from the interior of the main unit 1-1. The above-mentioned guide surface 1-311 is located on the side of the top of the air outlet channel 1-33 facing the interior of the main unit 1-1. When the water tank is assembled on the main unit 1-1, the handle 1-32 is also laid on the top of the air outlet channel 1-33 facing the inside of the main unit 1-1, and the height of the handle 1-32 is not higher than the height of the top of the air outlet channel 1-33.

[0073] In conjunction with Figures 6 and 8, in some embodiments, the tank cover assembly 12-3 further includes a separator 1-6. Figure 9 shows a schematic structural diagram of the separator 1-6 in Figure 8. In conjunction with Figures 6, 8, and 9, the separator 1-6 is connected to the bottom of the cover body 1-31, and a first water leakage portion 1-61 is provided on the separator 1-6. When the tank cover assembly 12-3 is assembled in the water tank, the separator 1-6 divides the water tank into a first cavity located above the separator 1-6 and a second cavity located below the separator 1-6. The first cavity and the second cavity are connected through the first water leakage portion 1-61.

[0074] According to the box cover assembly 12-3 of some embodiments of the present disclosure, since the partition 1-6 is connected to the bottom of the cover body 1-31, when the box cover assembly 12-3 is assembled in the water tank, the partition 1-6 divides the water tank into a first cavity located above the partition 1-6 and a second cavity located below the partition 1-6, so that after the sewage sucked into the water tank together with the solid waste is sucked into the first cavity, the sewage flows into the second cavity through the first leakage part 1-61 to achieve solid-liquid separation.

[0075] Referring to Figures 6, 8, and 9, a separator 1-6 is disposed below the cover 1-31. The separator 1-6 may be plate-shaped and is positioned within the mounting hole 1-62 through which the water supply tank's pumping pipe 1-23 passes. When the water tank is in use, sewage within the tank is collected into the first cavity via the pumping pipe 1-23. Water from the sewage collected in the first cavity is then drained into the second cavity via the first leaking portion 1-61, allowing solid waste in the sewage to be stored in the first cavity. The sewage is then separated from the solid and liquid components by the separator 1-6.

[0076] Figure 10 shows a schematic top view of the separator in Figure 9. In conjunction with Figure 10, in some embodiments, the first water leakage portion 1-61 on the separator 1-6 may include multiple first water leakage holes, which may be arranged in an arc shape around the periphery of the mounting hole 1-62. In other embodiments, the multiple first water leakage holes on the separator 1-6 may also be arranged in a grid pattern, which is not a limitation here.

[0077] In conjunction with Figure 3, Figure 6, and Figures 8-10, in some embodiments, the suction pipe 1-23 is connected to the side wall of the water tank, and the mounting hole 1-62 is open toward one side of the side wall for the suction pipe 1-23 to pass through. In some embodiments, the suction pipe 1-23 can be integrated into the side wall of the water tank, and a water outlet is provided at the top of the suction pipe 1-23. Thus, when the water tank is in use, the sewage in the water tank is collected into the first cavity through the top of the suction pipe 1-23. The water in the sewage collected in the first cavity is drained into the second cavity through the first leaking portion 1-61, so that the solid waste in the sewage is stored in the first cavity, and the sewage is separated into solid and liquid by the partition 1-6. In other embodiments, a water outlet can also be provided on the circumferential surface of the suction pipe 1-23 above the partition 1-6, and the sewage in the water tank can also be collected into the first cavity. This is not limited here.

[0078] In conjunction with Figure 6 and Figures 8-10, at least part of the periphery of the separator 1-6 is elastically abutted against the inner wall of the water tank to improve the sealing effect between the separator 1-6 and the inner wall of the water tank. In some embodiments, a seal 1-63 can be provided around the periphery of the separator 1-6 except for the opening, and the water extraction pipe 1-23 and the opening can be matched with a small gap. In some embodiments, the seal 1-63 can also be provided between the pipe wall and the opening of the water extraction pipe 1-23, which will not be described in detail here. In other embodiments, the periphery of the separator 1-6 can be elastic. In some embodiments, a plate of elastic material is injection molded around the periphery of the separator 1-6 so that when the box cover assembly 12-3 is assembled on the water tank, the periphery of the separator 1-6 can be appropriately compressed to improve the sealing effect between the separator 1-6 and the inner wall of the water tank.

[0079] FIG11 shows a schematic structural diagram of the divider in FIG9 from another perspective. In conjunction with FIG6 and FIG8-11, the tank cover assembly 12-3 may further include a trash baffle 1-7, which is connected to the divider 1-6. The trash baffle 1-7 is disposed within the first cavity, i.e., the trash baffle 1-7 is connected to the top of the divider 1-6. The trash baffle 1-7 is provided with a second leaking portion 1-71, and the first leaking portion 1-61 is provided on one side of the trash baffle 1-7. When the tank cover assembly 12-3 is removed from the tank body 12-b1, the provision of the trash baffle 1-7 can concentrate the trash in the water tank in the area enclosed by the divider 1-6 and the trash baffle 1-7, preventing the trash from falling directly onto the ground, thus avoiding secondary contamination and facilitating trash cleaning.

[0080] In conjunction with Figures 6 and 8-11, in some embodiments, the trash baffle 1-7 may be connected only to at least a portion of the periphery of the divider 1-6. In some embodiments, the trash baffle 1-7 may be connected to the side of the divider 1-6 away from the main unit 1-1, i.e., the trash baffle 1-7 is disposed on the rear side of the divider 1-6. When the user removes the lid assembly 12-3 from the tank body 12-b1, the water tank will face the user, i.e., the water tank will tilt toward the rear. With the trash baffle 1-7 attached to the rear side of the divider 1-6, when the lid assembly 12-3 is removed, if sewage is present in the first chamber, the sewage will flow through the second leaking portion 1-71 of the trash baffle 1-7 to the area behind the trash baffle 1-7, and the garbage will be stored in the area in front of the divider 1-6 and the trash baffle 1-7, making it easier for the user to clean the garbage.

[0081] In combination with Figure 6 and Figures 8-11, in some embodiments, the second water leakage part 1-71 may include a second water leakage hole arranged in a grid shape on the garbage baffle 1-7 to prevent sewage from remaining at the junction of the garbage baffle 1-7 and the partition 1-6, so as to avoid the phenomenon of leakage outside the water tank causing secondary pollution after the box cover assembly 12-3 is disassembled.

[0082] In conjunction with Figures 6 and 8-11, in some embodiments, a first water leakage portion 1-61 can be provided on the front side of the garbage baffle 1-7 to securely separate the first and second cavities formed by the separator 1-6. A relief portion 1-72 is provided on the side of the garbage baffle 1-7 facing away from the main unit 1-1 (i.e., the rear side). The relief portion 1-72 extends toward the interior of the main unit 1-1 (i.e., the front side) to form a diversion channel. A third water leakage portion 1-64 is provided on the separator 1-6, at least a portion of which is located within the projection of the relief portion 1-72. The third water leakage portion 1-64 can be a third water leakage hole, which is located directly below the relief portion 1-72. When the cleaning device is in use, sewage is present between the garbage baffle 1-7 and the water tank. The relief portion 1-72 and the third water leakage portion 1-64 are provided to divert sewage into the water tank. When the tank cover assembly 12-3 is removed, sewage behind the garbage baffle 1-7 can flow into the water tank through the avoidance portion 1-72 and the third leaking portion 1-64. In other embodiments, a gap can be provided between the garbage baffle 1-7 and the rear wall of the water tank body 12-b1, and the garbage baffle 1-7 can be provided with a first leaking portion 1-61 on both the front and rear sides. When the tank cover assembly 12-3 is removed, sewage behind the garbage baffle 1-7 can flow into the water tank through the gap and the third leaking portion 1-64.

[0083] In other embodiments, the trash baffles 1-7 can also be mounted around the top of the divider 1-6. When the lid assembly 12-3 is removed, the trash is retained on the divider 1-6 between the trash baffles 1-7. However, this assembly method requires the lid assembly 12-3 to be inverted or manually cleaned. Compared to the above-mentioned method in which the trash baffles 1-7 are attached to a portion of the divider 1-6, the trash cleaning is more difficult and is therefore an alternative method.

[0084] In conjunction with Figures 6 and 8 , in some embodiments, the tank cover assembly 12-3 further includes a flow guide 1-8. The flow guide 1-8 is positioned above the mounting hole 1-62 of the divider 1-6. When the tank cover assembly 12-3 is installed within the water tank, the flow guide 1-8 is positioned above the suction pipe 1-23. When the water tank is in use, sewage within the water tank is ejected through the top of the suction pipe 1-23, blocked by the flow guide 1-8, and then collected within the first chamber.

[0085] 6 and 8 , in some embodiments, the guide member 1-8 may be a U-shaped structure, with the opening of the U-shaped structure of the guide member 1-8 facing downward, and the side walls on both sides of the guide member 1-8 may be connected to the partition 1-6 through a bracket 1-9.

[0086] In some embodiments, a sealing plate 1-81 may be provided on the rear side of the guide member 1-8 so that the guide groove forms a cover structure with a bottom and a front opening.

[0087] In conjunction with Figures 6-8, in some embodiments, the cover 1-31 can be integrally formed on the top of the deflector 1-8. An air inlet 1-34 is provided on the side wall of the cover 1-31. The air inlet 1-34 is provided above the deflector 1-8. The air inlet 1-34 serves as the entrance to the air inlet channel to guide air out of the water tank.

[0088] According to some embodiments of the water tank of the present disclosure, since at least part of the outer peripheral surface of the water tank body is provided with anti-slip grooves, and the anti-slip grooves are provided on the outside of the main unit, the user can hold the body with anti-slip grooves to remove the water tank from the main unit of the cleaning device, thereby avoiding to a certain extent the risk of the water tank falling off during the disassembly process, causing the sewage in the water tank to spill onto the ground and form secondary pollution, which has good practicality. In the second aspect of the present disclosure, an electrode assembly is provided. Figure 12 shows a schematic structural diagram of the electrode assembly according to some embodiments of the present disclosure, and Figure 13 shows a schematic structural diagram of the electrode assembly according to other embodiments of the present disclosure. In combination with Figures 12 and 13, the present disclosure provides an electrode assembly, which includes a pole and a shell. The shell is wrapped around the pole, and the shell is provided with at least two exposed parts for exposing the pole, so that when the water tank is in an upright state, the heights of the at least two exposed parts are different, so as to form at least two trigger parts on the pole that are not at the same height.

[0089] According to the electrode assembly 2-a of some embodiments of the present disclosure, since the shell 2-2 is wrapped around the pole 2-1, the shell 2-2 is provided with at least two exposed parts for exposing the pole 2-1, so that when the water tank is in an upright state, the heights of the two or more exposed parts are different, so as to form at least two triggering parts on the pole 2-1 that are not at the same height, that is, at least two triggering parts can be provided on one electrode assembly 2-a, so that at least two water level detectors can be replaced by one electrode assembly 2-a to simplify installation and have good practicality.

[0090] In conjunction with Figures 12 and 13 , in some embodiments, the triggering portion includes a first triggering portion 2-11. The bottom end of the pole 2-1 extends beyond the bottom of the housing 2-2. The portion of the pole 2-1 extending beyond the bottom of the housing 2-2 can serve as the first triggering portion 2-11. That is, in some embodiments, an exposed portion is provided at the bottom of the housing 2-2 to expose the bottom end of the pole 2-1. The bottom end of the pole 2-1 can come into contact with the water in the water tank 2-b, allowing the portion of the pole 2-1 extending beyond the bottom end of the housing 2-2 to serve as the first triggering portion 2-11.

[0091] With reference to FIG12 , in some embodiments, at least two electrodes 2-1 are arranged in parallel. The top ends of the at least two electrodes 2-1 are connected to the housing 2-2. The bottom ends of the at least two electrodes 2-1 extend out of the bottom of the housing 2-2 to serve as at least two first triggering portions 2-11, thereby providing the electrode assembly 2-a with at least two first triggering portions 2-11.

[0092] 12 , in some embodiments, at least two first triggering portions 2 - 11 are not at the same height to achieve detection of different water levels.

[0093] Taking the example of an electrode assembly 2-a having two poles 2-1 and two first triggering portions 2-11 at different heights, the structure of the electrode assembly 2-a and its assembly within a water tank 2-b to detect the water level within the water tank 2-b will be further described. For ease of description, the first triggering portion 2-11 located at the bottom is defined as a first water level triggering portion 2-111, and the first triggering portion 2-11 located at the top is defined as a second water level triggering portion 2-112.

[0094] In conjunction with Figure 12, the shell 2-2 includes a connecting seat 2-21 and a sleeve 2-22, and the connecting seat 2-21 is connected to the top of the pole 2-1. The sleeve 2-22 can be connected to the bottom of the connecting seat 2-21 in an integral manner. The sleeve 2-22 and the pole 2-1 are correspondingly arranged, the sleeve 2-22 is sleeved on the corresponding pole 2-1, and the exposed portion is arranged on the sleeve 2-22. When two poles 2-1 are set, the exposed portion of the sleeve 2-22 is arranged at the bottom of the sleeve 2-22, that is, the bottom ends of the two poles 2-1 both extend out of the bottom of the corresponding sleeve 2-22 to serve as two first triggering parts 2-11. The tops of the two sleeves 2-22 are roughly located in the same plane. The bottoms of the two sleeves 2-22 have different heights, and accordingly the lengths of the two poles 2-1 are also different, to form two first triggering parts 2-11 of different heights, namely a first water level triggering part 2-111 at the bottom and a second water level triggering part 2-112 at the top.

[0095] In conjunction with Figure 12, the electrode assembly 2-a may further include an electrode piece 2-3. Figure 14 shows a schematic structural diagram of the electrode piece 2-3 in Figure 12. In conjunction with Figures 12 and 14, one end of the electrode piece 2-3 is connected to the pole 2-1, a portion of the electrode piece 2-3 is disposed within the connection seat 2-21, and the other portion of the electrode piece 2-3 extends out of the connection seat 2-21 to serve as a connection end 2-32 for connecting to a contact piece on the tank cover assembly 12-3 of the water tank 2-b via a wire. When the tank cover assembly 12-3 of the water tank 2-b is assembled on the main unit of the cleaning device, the contact piece will contact and connect with the corresponding contact point of the main unit.

[0096] In some embodiments, a portion of the electrode 2-3 can be injection molded within the connector 2-21. The portion of the electrode 2-3 located within the connector 2-21 can be provided with a sleeve hole 2-31 corresponding to the pole 2-1 (as shown in FIG14 ), and the top of the pole 2-1 can be interference fit within the corresponding sleeve hole 2-31. The portion of the electrode 2-3 extending from the connector 2-21 can be adaptively bent according to the installation environment, so that the electrode 2-3 has an overall L-shaped or V-shaped structure.

[0097] Figure 15 shows a schematic structural diagram of the electrode assembly 2-a shown in Figure 12 equipped with a seal 2-4. In combination with Figures 12 and 15, in some embodiments, the electrode assembly 2-a may further include a seal 2-4, which is connected to the outer peripheral surface of the connecting seat 2-21 to improve the sealing effect of the electrode assembly 2-a assembled in the water tank 2-b. In some embodiments, a sealing groove 2-211 may be provided on the outer peripheral surface of the connecting seat 2-21. The seal 2-4 may be a sealing ring and is provided in the corresponding sealing groove 2-211. The seal 2-4 has a portion protruding from the outer peripheral surface of the connecting seat 2-21. When the electrode assembly 2-a is assembled on the tank cover assembly 12-3 of the water tank 2-b, the seal 2-4 is compressed, thereby improving the sealing effect of the electrode assembly 2-a assembled in the water tank 2-b.

[0098] 12 , in some embodiments, a positioning groove 2-212 may be further provided on the outer circumferential surface of the connection base 2-21. When the electrode assembly 2-a is assembled on the tank cover assembly 12-3 of the water tank 2-b, a corresponding protrusion is provided on the tank cover assembly 12-3 to insert into the positioning groove 2-212, thereby improving the reliability of the electrode assembly 2-a being assembled on the tank cover assembly 12-3 of the water tank 2-b.

[0099] In conjunction with Figure 12, in some embodiments, the cross-section of the connector 2-21 can be oval-shaped. When the electrode assembly 2-a is assembled on the tank cover assembly 12-3 of the water tank 2-b, the oval-shaped connector 2-21 has a rotation-proof function, thereby improving the reliability of the electrode assembly 2-a assembled on the tank cover assembly 12-3 of the water tank 2-b. In other embodiments, the cross-section of the connector 2-21 can also be a non-circular shape, such as a square or trapezoidal shape, and this is not limited here.

[0100] Figure 16 shows a schematic diagram of the structure of a water tank 2-b having the electrode assembly 2-a shown in Figure 12, and Figure 17 shows a schematic diagram of the structure of the tank cover assembly in Figure 16. In conjunction with Figures 16 and 17, the electrode assembly 2-a is mounted on the tank cover assembly 12-3 of the water tank 2-b, while the electrode assembly 2-a is used to detect the water level of the water tank 2-b. The tank cover assembly 12-3 of the water tank 2-b is also provided with a first electrode 2-6 and a second electrode 2-7. Both the first electrode 2-6 and the second electrode 2-7 are connected to the tank cover assembly 12-3. The first electrode 2-6 has a third triggering unit 2-61. The second electrode 2-7 has a fourth triggering unit 2-71. The third triggering part 2-61 is provided above the fourth triggering part 2-71, the fourth triggering part 2-71 cooperates with the first water level triggering part 2-111, and the third triggering part 2-61 cooperates with the second water level triggering part 2-112 to detect the water level of the water tank 2-b in different postures, specifically:

[0101] Figure 18 shows a schematic diagram of water level detection for the water tank 2-b shown in Figure 16 in an upright position. In conjunction with Figure 18 , when the water tank 2-b is at a first target water level, the water within the water tank 2-b conducts through the fourth trigger unit 2-71 and the first water level trigger unit 2-111, thereby outputting a first trigger signal to the host controller. Upon receiving the first trigger signal, the controller outputs a water level warning message. Specifically, the fourth trigger unit 2-71 and the first water level trigger unit 2-111 cooperate to output a first water-full message, alerting the user to the water level within the water tank 2-b. The device may then stop operating and issue a warning message to the user to clean the water tank 2-b. This water level warning message may be an audible or visual signal, without limitation. The first target water level may be the water level within the water tank 2-b when the device is in an upright position or tilted at an angle greater than or equal to 30°.

[0102] In some embodiments, the fourth trigger unit 2-71 can be located below the first water level trigger unit 2-111. When the body of the cleaning equipment is twisted, the water in the water tank 2-b twists accordingly, so that the fourth trigger unit 2-71 and the first water level trigger unit 2-111 are connected through the water in the water tank 2-b to realize water level detection under the twisted posture of the body.

[0103] FIG19 shows a schematic diagram of water level detection of the water tank 2-b shown in FIG16 in an inclined posture. In conjunction with FIG19 , when the water tank 2-b is at the second target water level, the water in the water tank 2-b conducts the third trigger unit 2-61 and the second water level trigger unit 2-112 to output a second trigger signal to the controller, so that the controller that receives the second trigger signal outputs a water full message, the device stops working, and sends a warning message to the user to clean the water tank 2-b. The warning message can be a sound or light warning, which is not limited here. The second target water level can be the water level in the water tank 2-b when the fuselage is in an inclined posture and the tilt angle can be less than or equal to 30° (including when the fuselage is in a flat state).

[0104] In conjunction with Figure 17, in some embodiments, two electrode assemblies 2-a can be arranged relative to each other. The two electrode assemblies 2-a can be symmetrically arranged along the width direction (i.e., the left-right direction) of the box cover assembly 12-3 with the vertical center line of the box cover assembly 12-3. Therefore, when the cleaning device is twisted to the left or right, the fourth trigger part 2-71 will be connected to the first water level trigger part 2-111 through the water body, and the third trigger part 2-61 will be connected to the second water level trigger part 2-112 through the water body, realizing water level detection when the body is twisted.

[0105] In conjunction with Figure 13, in some other embodiments, the trigger part also includes a second trigger part 2-12. The electrode assembly 2-a may be provided with only one pole 2-1, the bottom end of which extends out of the sleeve 2-22 to serve as the first trigger part 2-11 located below. A water outlet 2-221 is provided on the shell 2-2 (sleeve 2-22), and the water outlet 2-221 can serve as the exposed part of the shell 2-2. Under the condition of being used for sewage to pass through, the water outlet 2-221 can also expose the pole 2-1 to form a trigger part on the pole 2-1. The trigger part is the second trigger part 2-12 located above. The water level detection principle of the electrode assembly 2-a in this embodiment is similar to that described above and will not be elaborated here.

[0106] In conjunction with Figure 13, in some other embodiments, the cross-section of the connection base 2-21 of the housing 2-2 can be circular. To improve the reliability of the assembly of the connection base 2-21 on the box cover assembly 12-3, at least one cut surface 2-213 can be provided on the outer circumference of the connection base 2-21 to prevent the connection base 2-21 from rotating on the box cover assembly 12-3. In some embodiments, the cut surface 2-213 can be provided on two opposite side surfaces of the connection base 2-21, and the cut surface 2-213 can be flat.

[0107] In other embodiments, water openings 2-221 may be opened at different positions of the sleeve 2-22, so that two parts of the pole 2-1 are exposed to serve as the first triggering part 2-11 and the second triggering part 2-12 located below, which will not be elaborated here.

[0108] It should be noted that the housing 2-2 can be made of hydrophobic and oleophobic Teflon or PP, and its surface is smooth, effectively preventing the attachment of sewage within the water tank 2-b. Furthermore, the sleeve 2-22 provided on the electrodes for water level detection prevents the formation of a water film between the electrodes from causing conduction and leading to false water level alarms, thus providing excellent practicality.

[0109] In a third aspect of the present disclosure, the present application further provides a water tank 2-b. Referring to FIG5 , the water tank 2-b comprises a tank body 12-b1, a tank cover 12-3, and the electrode assembly 2-a. The tank cover 12-3 is detachably disposed within the inlet and outlet 12-b2, and the electrode assembly 2-a is connected to the tank cover 12-3.

[0110] The water tank 2-b having the above-mentioned electrode assembly 2-a can have at least two triggering parts on one electrode assembly 2-a. In this way, one electrode assembly 2-a can be used to replace at least two water level detectors to simplify installation and has good practicality.

[0111] In a fourth aspect of the present disclosure, a cleaning device is further provided, which includes the above-mentioned water tank 2-b.

[0112] The cleaning device with the water tank can have at least two triggering parts on one electrode assembly, so that at least two water level detectors can be replaced by one electrode assembly to simplify installation and have good practicality.

[0113] In a fifth aspect of the present disclosure, a cleaning device is further provided, comprising a main unit 1-1 and the aforementioned water tank, wherein the main unit 1-1 is provided with a accommodating cavity 1-11, and the accommodating cavity 1-11 is provided with an assembly port communicating with the outside of the main unit 1-1; the water tank comprises a box body 12-b1, and at least a portion of the box body 12-b1 is detachably assembled within the accommodating cavity 1-11 via the assembly port. A button 1-12 is provided on the main unit 1-1, and a user can press the button 1-12 on the main unit 1-1 to release the connection between the water tank and the main unit 1-1. The user can then grasp the water tank and remove it from the main unit 1-1, thereby avoiding, to a certain extent, the risk of the water tank falling off during removal, causing the sewage in the water tank to spill onto the ground and cause secondary pollution, thereby having good practicality.

[0114] The cleaning device may be a mop or other types of cleaning devices. In some embodiments, it may be a water suction machine or a sweeping device, etc., which is not limited here.

[0115] The present disclosure provides an electrode assembly, a water tank, and a cleaning device, which are intended to at least to some extent avoid the risk of the water tank falling off during the disassembly process, causing the sewage in the water tank to spill onto the ground and cause secondary pollution; and to at least to some extent solve the technical problem of setting too many water level detectors in the water tank, which will cause cumbersome installation.

When the user holds the box cover assembly by the handle, the limiting portion can limit the handle so that the handle remains in a vertical position. When the box cover assembly is in place, the user releases the handle, and the handle can rotate to the top of the cover under the action of gravity, so as to facilitate the assembly of the water tank on the main unit of the cleaning device.

[0123] In some embodiments, the limiting portion corresponds to an end portion of the handle, and the end portion of the handle can be pressed against the corresponding limiting portion.

[0124] In some embodiments, a guide surface is provided on the top of the top cover, extending downward from the stop toward the interior of the main unit, with an obtuse angle between the guide surface and the stop. The handle can be rotated onto the guide surface of the cover. Once the tank cover assembly is fully assembled, the user releases the handle, which can then rotate under gravity onto the guide surface of the cover, facilitating assembly of the water tank onto the main unit of the cleaning device.

[0125] In some embodiments, the tank cover assembly further includes: a partition connected to the bottom of the cover body, the partition being provided with a first water leakage portion, the partition dividing the water tank into a first cavity located above the partition and a second cavity located below the partition, the first cavity and the second cavity being connected through the first water leakage portion.
