[0002] The present disclosure pertains to the technical field of household appliances, and in particular, relates to a wastewater tank for a cleaning device and a cleaning device.BACKGROUND

[0003] In the related art, a wastewater tank is an important component of a cleaning device (e.g., a sweeping robot or a floor-cleaning machine), and its main functions are to collect, separate, and store dry and wet debris. The working principle of the wastewater tank is as follows: an air induction member extracts air from within the wastewater tank so as to create a negative pressure therein, thereby drawing wastewater together with solid debris into the wastewater tank.

[0004] In the course of implementing the present disclosure, the inventor has found at least the following disadvantages in the related art.

[0005] After the cleaning device finishes operating, the interior of the wastewater tank needs to be cleaned; however, it is inconvenient to pour out the solid debris in the wastewater tank together with the wastewater in the case that the solid debris is present in the wastewater of the wastewater tank, thereby affecting user experience.SUMMARY

[0056] With the development of the economy and the progress of society, people's requirements for the quality of life have been increasing. Accordingly, various intelligent appliances capable of freeing users from manual labor have emerged, and cleaning devices for household use have gradually entered people's daily lives. Taking a floor-cleaning machine as the cleaning device as an example, the technical solutions of the present disclosure are further described.

[0057] The floor-cleaning machine is a type of cleaning device that is suitable for cleaning a floor surface while simultaneously suctioning wastewater and removing the wastewater from the site, and has advantages such as being environmentally friendly, energy-saving, and efficient. A wastewater tank is an important component of the floor-cleaning machine, configured to perform gas-liquid separation and to collect the separated wastewater in its own chamber. It is necessary to detect the amount of wastewater stored in the wastewater tank to determine whether the wastewater tank needs to be cleaned.

[0058] In the related art, after the cleaning device finishes operating, the interior of the wastewater tank needs to be cleaned; however, it is inconvenient to pour out the solid debris in the wastewater tank together with the wastewater in the case that the solid debris is present in the wastewater of the wastewater tank, thereby affecting user experience.

[0059] In a first aspect of the present disclosure, the present disclosure provides a wastewater separator detachably mounted on a wastewater tank of a cleaning device.

[0060] FIG. 1 illustrates a schematic structural diagram of a wastewater tank according to one or more embodiments of the present disclosure, and FIG. 2 illustrates a schematic structural diagram of the tank cover assembly in FIG. 1 in a first view. With reference to FIGs. 1 and 2, the tank cover assembly includes a cover body 1 and a partition member 2. FIG. 3 illustrates a schematic structural diagram of the wastewater separator in FIG. 2. With reference to FIGs. 1 to 3, the wastewater separator includes a partition member 2, and the partition member 2 is provided with a first drainage part 202. The partition member 2 divides the wastewater tank b into a first chamber located above the partition member 2 and a second chamber located below the partition member, and the first chamber is in communication with the second chamber via the first drainage part 202.

[0061] According to the wastewater separator provided in the present disclosure, since the partition member 2 divides the wastewater tank b into the first chamber located above the partition member 2 and the second chamber located below the partition member 2, the wastewater drawn into the wastewater tank b, after being drawn into the first chamber together with the solid debris, flows into the second chamber via the first drainage part 202, thereby achieving solid-liquid separation within the wastewater tank. In the case that the wastewater tank is cleaned, it is only necessary to pull a wastewater separator away from the wastewater tank b. That is, when the wastewater separator is detached from the wastewater tank b, during the pulling process, the wastewater in the wastewater tank b flows into the wastewater tank via the first drainage part 202, and the solid debris in the wastewater is retained on the partition member 2 of the wastewater separator, such that the debris is fixed and is separated from the wastewater tank b, and the contents in the wastewater separator and the wastewater tank b can be poured out separately, thereby enabling rapid cleaning of the solid debris and the wastewater, offering a better user experience, and achieving good practicability.

[0062] With reference to FIG. 3, the partition member 2 may be plate-shaped, and the partition member 2 is provided with a mounting hole 201 configured for a suction pipe e of the wastewater tank b to pass through. In the case that the wastewater tank b is used, the wastewater in the wastewater tank b is collected into the first chamber via the suction pipe e, and the water portion in the wastewater collected into the first chamber is guided into the second chamber via the first drainage part 202, such that the solid debris in the wastewater is stored into the first chamber, and solid-liquid separation of the wastewater is achieved via the partition member 2.

[0063] FIG. 4 illustrates a schematic top view of FIG. 3. With reference to FIGs. 3 and 4, in some embodiments, the first drainage part 202 on the partition member 2 may include a plurality of first drainage apertures, and the plurality of first drainage apertures may be arranged in an arc shape at the periphery of the mounting hole 201. In other embodiments, the plurality of first drainage apertures on the partition member 2 may also be arranged in a grid pattern, which is not limited herein.

[0064] In some embodiments, the wastewater tank b is provided with a mounting side wall, the suction pipe e is connected to the mounting side wall of the wastewater tank b, and the side of the mounting hole 201 facing the mounting side wall is open for the suction pipe e to pass through. In specific implementation, the suction pipe e may be integrated on the mounting side wall of the wastewater tank b, and a water outlet hole is provided at the top of the suction pipe e. In the case that the wastewater tank b is used, the wastewater in the wastewater tank b is collected into the first chamber via the top of the suction pipe e, and the water portion in the wastewater collected into the first chamber is guided into the second chamber via the first drainage part 202, such that the solid debris in the wastewater is stored into the first chamber, and solid-liquid separation of the wastewater is achieved via the partition member 2. In other embodiments, a water outlet hole may also be provided on the peripheral surface of the suction pipe e located above the partition member 2, and the wastewater in the wastewater tank b may also be collected into the first chamber, which is not limited herein.

[0065] With reference to FIGs. 2 to 4, at least part of the periphery of the partition member 2 elastically abuts against the interior wall of the wastewater tank b to improve the sealing effect between the partition member 2 and the inner wall of the wastewater tank b. In some embodiments, a first sealing member 203 may be provided on the periphery of the partition member 2 except at an opening portion thereof, and the suction pipe e and the opening may be fitted with a slight gap. Certainly, the first sealing member 203 may alternatively be provided between the pipe wall of the suction pipe e and the opening, and the details are not described herein. In other embodiments, the periphery of the partition member 2 may have elasticity, for example, by injection molding a plate made of an elastic material on the periphery of the partition member 2, such that, in the case that the wastewater separator is assembled in the wastewater tank b, the periphery of the partition member 2 can be appropriately compressed to improve the sealing effect between the partition member 2 and the inner wall of the wastewater tank b.

[0066] FIG. 5 illustrates a schematic structural diagram of FIG. 3 in another view. With reference to FIGs. 2 to 5, the wastewater separator may further include a debris baffle 3. The debris baffle 3 is connected to the partition member 2, and the debris baffle 3 is disposed in the first chamber, that is, the debris baffle 3 is connected to the top of the partition member 2. A second drainage part 301 is disposed on the debris baffle 3, and the first drainage part 202 is disposed on a side of the debris baffle 3. When the wastewater separator is detached from the wastewater tank b, the arrangement of the debris baffle 3 can concentrate the debris in the wastewater tank b on the region enclosed by the partition member 2 and the debris baffle 3, thereby preventing the debris from directly dropping to the ground, avoiding secondary contamination, and facilitating the disposal of the debris.

[0067] With reference to FIGs. 2 to 5, in some embodiments, the debris baffle 3 may be connected only to at least part of the periphery of the partition member 2. For example, the debris baffle 3 is preferably connected to the rear side of the partition member 2. In actual implementation, when a user detaches the wastewater separator from the wastewater tank b, the wastewater tank b is oriented toward the user, that is, the wastewater tank b is inclined toward the rear side. In the case that the debris baffle 3 is connected to the rear side of the partition member 2, when the wastewater separator is detached, if wastewater is present in the first chamber, the wastewater flows to a region at the rear side of the debris baffle 3 via the second drainage part 301 on the debris baffle 3, while the debris is stored in a region at a front side of the partition member 2 and the debris baffle 3, thereby facilitating cleaning of the debris by the user.

[0068] With reference to FIGs. 3 and 5, in some embodiments, the second drainage part 301 may include second drainage apertures arranged in a grid pattern on the debris baffle 3, so as to avoid wastewater from remaining at a junction of the debris baffle 3 and the partition member 2, and thus to avoid the phenomenon of secondary contamination caused by leakage of the wastewater to the outside of the wastewater tank b after the wastewater separator is detached.

[0069] With reference to FIGs. 2 to 5, in some embodiments, the first drainage part 202 may be disposed on a front side of the debris baffle 3, for fixedly separating the first chamber and the second chamber constructed by the partition member 2. At least part of the rear side of the debris baffle 3 is provided with a relief portion 302, and the relief portion 302 extends toward the front side of the partition member 2 to form a flow guide groove. The partition member 2 is provided with a third drainage part 204, at least part of the third drainage part 204 is disposed within the projection of the relief portion 302, and the third drainage part 204 may be a third drainage aperture and disposed right below the relief portion 302. During use of the cleaning device, wastewater is present between the debris baffle 3 and the wastewater tank b, and the arrangement of the relief portion 302 and the third drainage part 204 serves to make the wastewater flow into the wastewater tank, thereby serving a flow-guiding function. When the wastewater separator is detached, the wastewater located at the rear side of the debris baffle 3 may flow into the wastewater tank b via the relief portion 302 and the third drainage part 204. In other embodiments, a gap may be provided between the debris baffle 3 and the rear side wall of the tank body b1 of the wastewater tank b, and the first drainage part 202 is provided on both the front side and the rear side of the debris baffle 3. When the wastewater separator is detached, the wastewater located at the rear side of the debris baffle 3 may flow into the wastewater tank b through the gap and the third drainage part 204.

[0070] In other embodiments, the debris baffle 3 may also be disposed on the top of the partition member 2 in an enclosing manner. When the wastewater separator is detached, the debris is retained on the partition member 2 between the debris baffles 3. However, in this type of assembly arrangement, debris can only be cleaned by inverting the wastewater separator or by manual cleaning. Compared with the above solution in which the debris baffle 3 is connected to part of the periphery of the partition member 2, debris cleaning is simpler, which constitutes a preferred solution.

[0071] In a second aspect of the present disclosure, the present disclosure further provides a tank cover assembly a. The tank cover assembly includes a cover body 1 and the wastewater separator described above. The partition member 2 of the wastewater separator is connected below the cover body 1. In the case that the tank cover assembly a is assembled within the wastewater tank b, the partition member 2 divides the wastewater tank b into a first chamber located above the partition member 2 and a second chamber located below the partition member 2. The first chamber is in communication with the second chamber via the first drainage part 202.

[0072] According to the tank cover assembly a provided in the present disclosure, since the partition member 2 is connected below the cover body 1, and in the case that the tank cover assembly a is assembled within the wastewater tank b, the partition member 2 divides the wastewater tank b into a first chamber located above the partition member 2 and a second chamber located below the partition member 2, the wastewater drawn into the wastewater tank b, after being drawn into the first chamber together with the solid debris, flows into the second chamber via the first drainage part 202, thereby achieving solid-liquid separation within the wastewater tank b. In the case that the wastewater tank b is cleaned, it is only necessary to pull the tank cover assembly a away from the wastewater tank b. During the pulling process, the wastewater in the wastewater tank b flows into the wastewater tank b via the first drainage part 202, and the solid debris in the wastewater is retained on the partition member 2 of the tank cover assembly a, such that the contents in the tank cover assembly a and the wastewater tank b can be poured out separately, thereby enabling rapid cleaning of the solid debris and the wastewater, offering a better user experience, and achieving good practicability.

[0073] With reference to FIG. 2, in some embodiments, the tank cover assembly a further includes a flow guide cover 4, and the flow guide cover 4 is disposed above the mounting hole 201. In the case that the tank cover assembly a is assembled within the wastewater tank b, the flow guide cover 4 is disposed above the suction pipe e in a spacing manner. In the case that the wastewater tank b is used, the wastewater in the wastewater tank b is ejected out through the top of the suction pipe e, is blocked by the flow guide cover 4, and then collected into the first chamber.

[0074] With reference to FIG. 2, in specific implementation, the flow guide cover 4 may be of a U-shaped structure, the opening of the U-shaped structure of the flow guide cover 4 faces downward, and the side walls on both sides of the flow guide cover 4 may be connected to the partition member 2 via a support 5.

[0075] With reference to FIG. 2, in some embodiments, a partition plate 401 may be disposed on the rear side of the flow guide cover, such that the flow guide groove forms a cover structure having a bottom and a frontside opening.

[0076] In addition, in the related art, when the floor-cleaning machine is in operation, the water portion in the wastewater tank may collide with the inner wall of the wastewater tank to produce splashes. When the air induction member is in operation, the splashes may be drawn into the air induction member, affecting the normal operation of the air induction member.

[0077] In view of the above technical problems, the present disclosure provides a tank cover assembly. In the case that the above partition member is included, the cover body 1 is further provided with an air inlet 102, and portions of the cover body 1 that are located on both sides of the air inlet 102 abut against the inner wall of the wastewater tank b, such that the first chamber can be approximately divided into two parts. Splashes generated by water located in a part opposite to the air inlet 102 are blocked by the portions of the cover body 1 that are located on both sides of the air inlet 102, thereby, to a certain extent, preventing splashes generated by collision of the water portion in the wastewater tank b with the inner wall of the wastewater tank b from being drawn into the air induction member d, ensuring that the air induction member d can operate normally, and achieving good practicability.

[0078] With reference to FIG. 2, in some embodiments, the cover body 1 may be integrally formed at the top of the flow guide cover 4, and the air inlet 102 is disposed on the side wall of the cover body 1, that is, the air inlet 102 is disposed above the flow guide cover 4. The cover body 1 is further connected to two water blocking members 7. The two water blocking members 7 are disposed on both sides of the air inlet 102. In the case that the tank cover assembly a is assembled within the wastewater tank b, the two water blocking members 7 abut against the inner wall of the wastewater tank b. The two water blocking members 7 and the cover body 1 can approximately divide the first chamber into two parts. Splashes generated by water located in a part opposite to the air inlet 102 are blocked by the water blocking members 7 on the cover body 1 that are located on both sides of the air inlet 102, thereby, to a certain extent, preventing splashes generated by collision of the water portion in the wastewater tank b with the inner wall of the wastewater tank b from being drawn into the air induction member d, ensuring that the air induction member d can operate normally.

[0079] In some embodiments, the air inlet 102 may be disposed on the front side of the cover body 1, and the two water blocking members 7 are disposed on both sides of the width direction of the cover body 1. The two water blocking members 7 and the cover body 1 can divide the first chamber into two parts, i.e., a front part and a rear part. When the cleaning device works in a backward tilting or laying-flat state, the two water blocking members 7 can block water underneath the two water blocking members 7 (at an upper rear portion of the wastewater tank b), thereby preventing splashes generated by collision of the water with the cover support 5 of the wastewater tank b from being drawn into the exhaustduct, such that the air induction member d can operate normally.

[0080] In some embodiments, the two water blocking members 7 and the wastewater tank b may be integrally formed, and at least parts of the two water blocking members 7 can elastically abut against the inner wall of the wastewater tank b to improve the sealing effect between the water blocking members 7 and the inner wall of the wastewater tank b. In specific implementation, a second sealing member 701 (as shown in FIG. 2) may be provided on the outer side edges of the two water blocking members 7, or the outer side edges of the water blocking members 7 may have elasticity, for example, by injection molding a plate made of an elastic material on the outer side edges of the water blocking members 7, such that, in the case that the tank cover assembly a is assembled in the wastewater tank b, the peripheries of the water blocking members 7 can be appropriately compressed to improve the sealing effect between the water blocking members 7 and the inner wall of the wastewater tank b.

[0081] With reference to FIG. 2, in some embodiments, the cover body 1 is provided with an air outlet chamber 101, the air inlet 102 is disposed on the side wall of the air outlet chamber 101, and the bottom of the air outlet chamber 101 is provided with a water baffle part 103 to block the wastewater in the wastewater tank b from entering the air outlet chamber 101. When the cleaning device works in a forwardly inclined or lying-flat state, the water baffle part 103 can block the water portion in the wastewater tank b from entering the air outlet chamber 101 through the air inlet 102, and also prevent the water portion from further entering the air induction member d, thereby serving to protect the air induction member d. When the cleaning device is tilted in other directions, since no air inlet 102 is provided at other portions of the air outlet chamber 101, the water portion in the wastewater tank b cannot enter the air outlet chamber 101 either, such that the phenomenon that the water portion in the wastewater tank b enters the air induction member d through the air inlet 102 can be ameliorated to ensure the normal operation of the air induction member d to a certain extent, achieving good practicability.

[0082] In some embodiments, at least part of the bottom of the air outlet chamber 101 is provided with an inclined surface, the side of the inclined surface facing the air inlet 102 is lower than the side of the inclined surface distal to the air inlet 102, and the inclined surface is configured as the water baffle part 103. When the cleaning device works in a forwardly inclined or lying-flat state, the water baffle part 103 can block the water portion in the wastewater tank b from entering the air outlet chamber 101 through the air inlet 102, and also prevent the water portion from further entering the air induction member d, thereby serving to protect the air induction member d. Only one inclined surface may be provided, or a plurality of inclined surfaces may be provided along the air intake direction (as shown in FIG. 6). Slopes of the plurality of inclined surfaces may be consistent or inconsistent, which is not limited herein.

[0083] In other embodiments, at least part of the bottom of the air outlet chamber 101 may further be provided with steps, and the steps may be configured as the water baffle part 103. When the cleaning device works in a forwardly inclined or lying-flat state, the water baffle part 103 can block the water portion in the wastewater tank b from entering the air outlet chamber 101 through the air inlet 102, and also prevent the water portion from further entering the air induction member d, thereby serving to protect the air induction member d. Only one step may be provided, or a plurality of steps may be provided consecutively and spaced apart from each other (as shown in FIG. 7), which is not limited herein.

[0084] In the related art, if the wastewater tank b is in a tilted posture, the surface of the water portion in the wastewater tank b is close to the air induction member d, and water droplets may be generated on the surface of the water portion in the wastewater tank b. When the air induction member d is in operation, excessive water droplets may be drawn into the air induction member d, affecting the normal operation of the air induction member d.

[0085] Based on the above technical problems, the present disclosure continues to improve the tank cover assembly a. FIG. 8 illustrates a schematic structural diagram of FIG. 2 in a second view, and FIG. 9 illustrates a schematic structural diagram of FIG. 2 in a third view. With reference to FIGs. 8 and 9, the tank cover assembly a further includes two first electrodes 8, the two first electrodes 8 are connected to the cover body 1 separately, and each of the first electrodes 8 is provided with a first trigger part 801 for generating a trigger signal when the two first trigger parts 801 are conducted by the water portion in the wastewater tank b, such that the cleaning device adjusts the operating parameter of the air induction member d according to the corresponding trigger signal.

[0086] FIG. 10 illustrates a schematic diagram of logical control of a cleaning device having the wastewater tank shown in FIG. 1. With reference to FIG. 10, according to the tank cover assembly a provided in the present disclosure, in the case that the two first trigger parts 801 are conducted by the water portion in the wastewater tank b, the two first trigger parts 801 generate a trigger signal, such that the cleaning device adjusts the operating parameter of the air induction member d according to the corresponding trigger signal, so as to reduce the operating power of the air induction member d when the wastewater tank b is in a tilted posture, thereby reducing the risk of water droplets generated on the surface of the water portion in the wastewater tank b being drawn into the air induction member d, ensuring the normal operation of the air induction member d, and achieving good practicability. The tilted posture is set as a target posture. When the cleaning device is in other postures, no water portion exists between the two first trigger parts 801, and the first trigger part 801 and the second trigger part 1001 are not conducted. No trigger signal for adjusting the operating parameter of the air induction member d is generated, such that the air induction member d resumes the normal preset power value, thereby enabling the device to operate normally.

[0087] With reference to FIG. 10, the cleaning device may further include a controller c. When the wastewater tank b is in the target posture, the water portion in the wastewater tank b conducts two first trigger parts 801 to output a trigger signal to the controller c, where the trigger signal may be defined as a first trigger signal. The controller c, upon receiving the first trigger signal, outputs a control signal to the air induction member d to reduce the operating power of the air induction member d, thereby reducing the risk of water droplets generated on the surface of the water portion in the wastewater tank b being drawn into the air induction member d, ensuring the normal operation of the air induction member d. When the wastewater tank b is in a posture other than the above target posture, no water portion exists between the two first trigger parts 801, the two first trigger parts 801 are not conducted, and the controller c cannot receive the above first trigger signal. Accordingly, the air induction member d cannot receive the control signal, and the air induction member d resumes the normal preset power value, thereby enabling the device to operate normally.

[0088] In the related art, when a floor-cleaning machine is in operation, compared to the wastewater tank b in a vertical state, the wastewater tank b in a tilted state causes the surface of the water portion in the wastewater tank b to generate more water droplets. Based on this, in the present disclosure, the target posture of the wastewater tank b is set to the tilted posture of the wastewater tank b, as shown in FIG. 11.

[0089] In addition, during the process of pushing and pulling the floor-cleaning machine by the user, more water droplets are also generated on the surface of the water portion in the wastewater tank b. Based on this, in the present disclosure, in the case that the wastewater tank b is inclined toward the back of the wastewater tank b, that is, in the case that the wastewater tank b is inclined toward the user, the posture in which the wastewater tank b is positioned is set as the target posture.

[0090] In some embodiments, the inclination angle of the wastewater tank b may be less than or equal to 20°, that is, only when the wastewater tank b is at the inclination angle, the controller c is triggered to output a control signal for reducing the operation of the air induction member d. When the wastewater tank b is at other angles, the air induction member d maintains the normally set operating power, such that the mopping machine has excellent cleaning efficiency.

[0091] With reference to FIG. 9, in some embodiments, the two first electrodes 8 are connected to the cover body 1 in parallel, and at least parts of the two first electrodes 8 are disposed below the cover body 1 so as to be respectively configured as two first trigger parts 801. As seen from the width direction of the wastewater tank b, the first trigger parts 801 of the two first electrodes 8 are located in the same direction. When the wastewater tank b is in the target posture and the water portion in the wastewater tank b submerges the first trigger parts 801 of the two first electrodes 8, the water portion in the wastewater tank b conducts the first trigger parts 801 of the two first electrodes 8 so as to transmit the control signal to the controller c.

[0092] FIG. 12 illustrates a schematic structural diagram of the first electrode in FIG. 9. With reference to FIG. 12, in some embodiments, the first electrode 8 may include a first electrode plate 802 and a second electrode plate 803. The first electrode plate 802 passes through the cover body 1 and extends below the bottom of the cover body 1, that is, the first electrode plate 802 is arranged vertically. A portion of the first electrode plate 802 arranged below the bottom of the cover body 1 is configured as the first trigger part 801. One end of the second electrode plate 803 is connected to the top end of the first electrode plate 802. The second electrode plate 803 is disposed on the top of the cover body 1. The second electrode plate 803 can be attached to the top of the cover body 1 along the front-rear direction. The entire portion of the first electrode plate 802 disposed below the bottom of the cover body 1 may serve as the first trigger part 801, or part of the portion of the first electrode plate 802 disposed below the bottom of the cover body 1 may serve as the first trigger part 801, which is not limited herein. The first electrode plate 802 and the second electrode plate 803 may form an inverted L-shaped structure. In other embodiments, the top end of the first electrode plate 802 may also extend out of the cover body 1, one end of the second electrode plate 803 is connected to the middle portion of the first electrode plate 802, and the first electrode plate 802 and the second electrode plate 803 form a tipped T-shaped structure.

[0093] With reference to FIG. 12, in some embodiments, the first electrode 8 may further include a third electrode plate 804. The bottom end of the third electrode plate 804 is connected to the other end of the second electrode plate 803, and the top end of the third electrode plate 804 extends in a direction away from the cover body 1. The upper end of the third electrode plate 804 may be connected to a contact piece provided on the cover body 1 via a lead wire. When the wastewater tank b is mounted on the main unit of the floor-cleaning machine, the first contact piece abuts against and is connected to a corresponding contact point of the main unit.

[0094] With reference to FIG. 9, the tank cover assembly a may further include an isolating member 9. The isolating member 9 is connected to the cover body 1. In some embodiments, the outer side of at least one first trigger part 801 is provided with the isolating member 9, and two isolating members 9 are provided. The outer side of each of the first trigger parts 801 is provided with the isolating member 9, and the isolating member 9 is provided with a water inlet hole 901. The isolating member 9 is an insulating member, and the arrangement of the isolating member 9 can prevent a water film from being formed between the two first trigger parts 801 and thus the two first trigger parts being connected with each other, so as to avoid generating the first trigger signal to the controller c when the wastewater tank b is not in the target posture. Meanwhile, the water inlet hole 901 formed on the isolating member 9 can allow the water portion to pass through for generating the first trigger signal. In specific implementation, the isolating member 9 may be made of plastic material, may be of a square structure, and may be integrally formed, snap-fitted, or bonded to the bottom of the cover body 1. The bottom of the isolating member 9 is open to serve as the water inlet hole 901 of the isolating member 9. Certainly, the water inlet hole 901 may alternatively be formed on the side part of the isolating member 9, which is not limited herein.

[0095] In other embodiments, the isolating member 9 may also be disposed between the two first trigger parts 801. The isolating member 9 may be plate-shaped, and may be integrally formed, snap-fitted, or bonded to the bottom of the cover body 1, and the details are not described herein.

[0096] With reference to FIGs. 8, 9, and 10, in some embodiments, the tank cover assembly a further includes a second electrode 10 and a third electrode 11, both connected to the cover body 1. The second electrode 10 has a second trigger part 1001, and the second trigger part 1001 is disposed below the partition member 2. The third electrode 11 has a fourth trigger part 1101, and the fourth trigger part 1101 is disposed below the partition member 2. In the case that the wastewater tank b is at the first target water level, the water portion in the wastewater tank b conducts the second trigger part 1001 and the fourth trigger part 1101 to output a second trigger signal to the controller c, and the controller c, upon receiving the second trigger signal outputs a water level warning message. That is, the second trigger part 1001 of the second electrode 10 cooperates with the fourth trigger part 1101 of the third electrode 11 to output the first water full information, so as to remind the user to pay attention to the water level of the water portion in the wastewater tank b. The device may stop operation and send a warning message for cleaning the wastewater tank b to the user. The water level warning message may be a sound or light message, which is not limited herein. The first target water level may be a water level in the wastewater tank b when the body of the device is in an upright posture, or in a tilted posture having an inclination angle greater than or equal to 30°.

[0097] With reference to FIGs. 8, 9, and 10, in some embodiments, the height of the fourth trigger part 1101 may be the same as or approximately the same as that of the second trigger part 1001. In other embodiments, the fourth trigger part 1101 may be disposed below the second trigger part 1001. That is, the bottom of the fourth trigger part 1101 is at a height difference from the second trigger part 1001. In the case that the body of the floor-cleaning machine is twisted, the water portion in the wastewater tank b is twisted correspondingly, such that the second trigger part 1001 and the fourth trigger part 1101 are conducted via the water portion in the wastewater tank b so as to achieve water level detection under the twisted posture of the body of the device, as shown in FIG. 13.

[0098] With reference to FIGs. 8, 9, and 10, in some embodiments, the second electrode 10 is further provided with a third trigger part 1002. The third trigger part 1002 is disposed between the cover body 1 and the partition member 2. That is, the second trigger part 1001 is disposed below the third trigger part 1002. In the case that the wastewater tank b is at the second target water level, the water portion in the wastewater tank b conducts the third trigger part 1002 and one of the first trigger parts 801 to output a third trigger signal to the controller c. The controller c, upon receiving the third trigger signal, outputs water full information. The device stops operation and sends a warning message for cleaning the wastewater tank b to the user. The warning message may be a sound or light warning, which is not limited herein. As shown in FIG. 14, the second target water level may be a water level in the wastewater tank b when the body of the device is in a tilted posture having an inclination angle less than or equal to 30°.

[0099] With reference to FIGs. 8 and 9, in some embodiments, two second electrodes 10 are disposed opposite to each other, and the two second electrodes 10 are disposed on both sides of the width direction of the third electrode 11. When the cleaning device is twisted leftward or rightward, the second trigger part 1001 and the third trigger part 1002 are electrically connected to the corresponding trigger part via the water portion, so as to achieve water level detection under the twisted posture of the body of the device, achieving good practicability, as shown in FIG. 13.

[0100] With reference to FIGs. 8 and 9, the two second electrodes 10 may be disposed on a side facing away from the user with respect to the third electrode 11, that is, the two second electrodes 10 may be disposed on a front side in the wastewater tank b. When the device is tilted forward or laid flat forward, the second trigger part 1001 and the third trigger part 1002 are electrically connected to the corresponding trigger part via the water portion in the wastewater tank b, so as to achieve water level detection under the tilted or lying-flat state of the body of the device, as shown in FIG. 14, achieving good practicability.

[0101] FIG. 15 illustrates a schematic structural diagram of the second electrode in FIGs. 8 and 9.

[0102] With reference to FIG. 15, in some embodiments, the second electrode 10 may further include a fourth electrode plate 1008 and a fifth electrode plate 1009. One end of the fourth electrode plate 1008 is disposed within the housing 1003, and the other end of the fourth electrode plate extends out of the housing 1003. The fourth electrode plate 1008 is connected to the first terminal post 1004 and the second terminal post 1005. The bottom end of the fifth electrode plate 1009 is connected to the other end of the fourth electrode plate 1008, and the top end of the fifth electrode plate 1009 passes through the cover body 1. The upper end of the fifth electrode plate 1009 may be connected to a contact piece provided on the tank cover assembly via a lead wire. When the wastewater tank b is mounted on the main unit of the floor-cleaning machine, the third contact piece abuts against and is connected to a corresponding contact point of the main unit.

[0103] In specific implementation, the housing 1003 may be connected, by means of overmolding, to corresponding portions of the terminal post and the electrode plate. A mounting hole matching the housing 1003 is formed on the cover body 1, and the housing 1003 is fixedly connected in the mounting hole. The first terminal post 1004 and the second terminal post 1005 may be inserted into the fourth electrode plate 1008 in an interference fit manner so as to achieve good electrical conductivity. The fifth electrode plate 1009 and the fourth electrode plate 1008 may be integrally formed, and the two may form an L-shaped structure or a T-shaped structure, which is not limited herein.

[0104] With reference to FIGs. 2, 3, 5, 8, and 9, in some embodiments, the top of the partition member 2 is provided with a waterproof member 12, and at least part of the second connection sleeve 1007 passes through the waterproof member 12. The waterproof member may have a sleeve-shaped structure and may be integrally formed on the top of the partition member 2. The second connection sleeve 1007 may be interference-fitted through the waterproof member to provide waterproof protection for the second connection sleeve 1007, thereby improving the service life of the second connection sleeve 1007 and the second terminal post 1005.

[0105] With reference to FIGs. 8 and 9, in some embodiments, the third electrode 11 may be disposed on a perpendicular bisector of the two second electrodes 10, or may be offset from the perpendicular bisector of the two second electrodes 10, which is not limited herein.

[0106] With reference to FIGs. 8 and 9, in some embodiments, the tank cover assembly a may further include a supporting member 13. The supporting member 13 may be plate-shaped, the top end of the supporting member is connected to the bottom of the partition plate 401, and the bottom end of the supporting member is connected to the partition member 2.

[0107] With reference to FIGs. 8 and 9, in some embodiments, the opening of the groove 1301 faces the rear side, and the relief portion 302 of the debris baffle 3 is connected to the rear side of the bottom of the groove 1301 to enclose part of the third electrode 11 between the relief portion 302 and the supporting member 13, so as to provide waterproof protection for the third electrode 11, thereby improving the service life of the third electrode 11.

[0108] It should be noted that non-trigger parts of each electrode plate may be covered with an electrode housing. The electrode housing may be made of hydrophobic and oleophobic Teflon or PP material, with a smooth surface that can effectively prevent wastewater in the wastewater tank b from adhering thereto. In addition, since the electrodes used for water level detection are columnar, they can prevent a water film formed between electrodes from conducting the electrodes, thereby avoiding false water level reporting and achieving good practicability.

[0109] In a second aspect of the present disclosure, the present disclosure further provides a wastewater tank b. With reference to FIG. 1, the wastewater tank b includes a tank body b1 and the above tank cover assembly a. The tank body b1 is provided with an inlet / outlet b2, and the cover body 1 of the above tank cover assembly a is detachably disposed within the inlet / outlet b2 of the tank body b1.

[0110] The wastewater tank b provided in the present disclosure can not only allow the contents in the tank cover assembly a and the wastewater tank b to be poured out separately for rapid cleaning of solid debris and wastewater, so as to offer a better user experience, but also can reduce the risk of splashes generated by collision of the water portion in the wastewater tank b with the inner wall of the wastewater tank b being drawn into the air induction member d, which may affect the normal operation of the air induction member d. The water level of the wastewater tank b in different postures can also be detected, and the water portion in the wastewater tank b can be prevented from entering the air induction member d, achieving good practicability.

[0111] In the related art, after the wastewater in the wastewater tank reaches the set water level, the wastewater tank needs to be detached from the main unit to clean the wastewater tank. During detachment of the wastewater tank, the wastewater tank is prone to falling, creating a risk that wastewater in the wastewater tank may spill onto the floor, causing secondary contamination.

[0112] FIG. 16 illustrates a schematic structural diagram of a cleaning device according to one or more embodiments of the present disclosure; FIG. 17 illustrates a schematic diagram of the cleaning device in FIG. 16 in an unlocked state; and FIG. 18 illustrates a schematic structural diagram of the wastewater tank in FIG. 16. With reference to FIGs. 1 to 3, the wastewater tank provided in the present disclosure is assembled on the main unit. The wastewater tank includes a tank body b1, and at least part of the outer peripheral surface of the tank body b1 is provided with anti-slip textures 13. In the case that the wastewater tank is assembled on the main unit 12, the anti-slip textures 13 are disposed on the exterior of the main unit 12.

[0113] According to the wastewater tank provided in the present disclosure, since at least part of the outer peripheral surface of the tank body b1 of the wastewater tank is provided with the anti-slip textures 13, and the anti-slip textures 13 are disposed on the exterior of the main unit 12, the user can hold the tank body b1 having the anti-slip textures 13 in hand to detach the wastewater tank from the main unit 12, such that, to a certain extent, the wastewater tank can be prevented from falling off during the detachment process, thereby preventing the risk of wastewater in the wastewater tank spilling onto the floor and causing secondary contamination, achieving good practicability.

[0114] With reference to FIG. 18, since at least part of the outer peripheral surface of the tank body b1 is provided with the anti-slip textures 13, and the anti-slip textures 13 are disposed on the outer side of the accommodating chamber 11, the user can hold the tank body b1 having the anti-slip textures 13 in hand to detach the wastewater tank, such that, to a certain extent, the wastewater tank can be prevented from falling off during the detachment process, thereby preventing the risk of wastewater in the wastewater tank spilling onto the floor and causing secondary contamination, achieving good practicability.

[0115] With reference to FIG. 18, in some embodiments, two anti-slip textures 13 may be provided. The two anti-slip textures 13 are respectively disposed on two sides of the width direction of the tank body b1, and the peripheral length between the two anti-slip textures 13 is substantially equal to the length of a human palm. When the user detaches the wastewater tank, the user's thumb acts on one anti-slip texture 13, and the remaining four fingers of the user act on the other anti-slip texture 13, that is, the two main force-bearing parts of the user's palm both act on the anti-slip textures 13, thereby accommodating the posture of the user holding the tank body b1 and facilitating the detachment of the wastewater tank from the main unit 12 by the user.

[0116] In some embodiments, the anti-slip textures 13 include a plurality of linear features arranged in the height direction of the tank body b1, and the plurality of linear features are arranged in parallel. In other embodiments, the anti-slip textures 13 may alternatively be disposed only in a middle portion, an end portion, or the like of the outer peripheral surface of the tank body b1, which is not limited herein.

[0117] It should be noted that the entire outer peripheral surface of the portion of the tank body b1 exposed to the main unit 12 may be provided with the anti-slip textures 13, which is not limited herein.

[0118] FIG. 19 illustrates a schematic structural diagram of FIG. 18 in another view. With reference to FIG. 19, in some embodiments, the wastewater tank further includes a tank cover assembly f. FIG. 20 illustrates a schematic diagram of a state in which a tank cover assembly is assembled into a tank body.
