[0054] An example of a cleaning device in a cleaning system is a floor scrubber. Floor scrubbers typically have a clean water tank that supplies cleaning fluid to the cleaning rollers as they mop the floor. After use, the floor scrubber is typically returned to the pile, where it is docked and supported. Self-cleaning of the device, such as automatic cleaning of the cleaning rollers, can be performed on the pile. The cleaning rollers can be, for example, strip-shaped cleaning rollers, circular cleaning brushes, or discs.

[0055] It should be noted that the present disclosure describes cleaning equipment using a floor scrubber as a preferred embodiment of the present disclosure and does not limit the scope of protection of the cleaning equipment of the present disclosure. For example, the cleaning equipment of the present disclosure may be a handheld floor scrubber with a handle and manually operated by a user, or an autonomously movable floor mopping robot with drive wheels that can control the movement of the drive wheels and the cleaning rollers to clean the floor according to a stored program. For another example, the cleaning equipment of the present disclosure may also be other cleaning equipment such as a mop, a sweeper, or an electric mop.

[0056] In the following, the embodiments of the present disclosure will be described in detail by taking an example in which the cleaning system includes a handheld floor scrubber and a pile body.

[0057] As shown in FIG1 , the pile body 20 includes a liquid supply tank 210 and a heating module 220 . The liquid supply tank 210 includes a receiving chamber, a liquid injection port, and a liquid discharge port. The liquid supply tank 210 is configured to receive cleaning liquid through the receiving chamber, the liquid injection port is used to add cleaning liquid to the receiving chamber, and the liquid discharge port is used to allow the cleaning liquid to flow out of the receiving chamber. The heating module 220 is configured to heat the cleaning liquid to a preset temperature. The pile body 20 is provided with a liquid outlet, through which the heated cleaning liquid can be supplied to the cleaning roller of the cleaning device 10 .

[0058] The pile body 20 provided in the present disclosure is provided with a liquid supply box 210 and a heating module 220. The heating module 220 can heat the cleaning liquid in the liquid supply box 210; a liquid outlet is provided on the pile body 20, and the heated cleaning liquid can be provided to the cleaning roller located on the pile body 20 through the liquid outlet, thereby cleaning the cleaning roller by the cleaning liquid heated to a preset temperature, thereby improving the cleaning effect of the cleaning roller.

[0059] The cleaning liquid injected into the liquid supply tank 210 may also be water or a solution of water and detergent, and the present disclosure does not impose any restrictions on this, as long as it can achieve a cleaning effect on the cleaning roller. When the cleaning liquid is water, the pile body 20 can be connected to tap water to directly inject liquid into the liquid supply tank 210. A water inlet valve can be provided on the inlet of the liquid supply tank 210 to control whether tap water is injected into the liquid supply tank 210. The control valve can be a solenoid valve, so that the control valve can be remotely controlled or automatically controlled by the system through an operating button or an operating interface to realize the water supply function, which is convenient for users to use and improves the degree of automation of the pile body 20.

[0060] The preset temperature of the cleaning liquid after being heated by the heating membrane assembly can be 40° to 70°, such as 40°, 45°, 50°, 55°, 60°, 65°, 70°, etc., which are not listed here. Keeping the cleaning liquid temperature above 40° can improve the cleaning effect of the cleaning liquid on the cleaning roller. Keeping the cleaning liquid temperature below 70° can prevent the formation of scale after the cleaning liquid is heated, and can also prevent the effect of excessive temperature on the activity of the cleaning liquid. Of course, the preset temperature of the cleaning liquid after being heated by the heating membrane assembly can also be less than 40° or greater than 70°, which is not limited by the present disclosure.

[0061] Heating module 220 can be an electric heating module, which has high heating efficiency and occupies relatively little space. Heating module 220 includes a heating inlet and a heating outlet. The heating inlet is connected to the outlet of liquid supply tank 210 via a pipeline. Cleaning liquid enters the receiving chamber of heating module 220 through the pipeline. The electric heating module is then configured to heat the cleaning liquid in the receiving chamber to a predetermined temperature.

[0062] Furthermore, the electric heating module may include an electric heating wire that can be directly wound around the pipe through which the cleaning liquid flows to heat the cleaning liquid. This means that the electric heating module does not require a heating chamber. This disclosure is not limited to this; any electric heating module capable of heating the cleaning liquid falls within the scope of protection of this disclosure.

[0063] The heating module 220 is connected between the liquid supply tank 210 and the liquid outlet and is located within the outer shell of the pile body 20. By arranging the heating module 220 within the outer shell of the pile body 20, that is, the pipeline for transmitting the cleaning liquid can be located within the outer shell of the pile body 20 when connected to the heating module 220, the pipeline for transmitting the cleaning liquid can be relatively short, thereby avoiding the temperature drop caused by the pipeline being too long, and improving the heating effect. In particular, the heating module 220 can be arranged in a cleaning seat connected to the pile body to further shorten the hot water outflow path and maintain the temperature. At the same time, by arranging the pipeline for transmitting the cleaning liquid within the outer shell of the pile body 20, the external ambient temperature of the outer shell is prevented from excessively affecting the temperature of the cleaning liquid in the pipeline, thereby improving the control accuracy of the heating temperature of the cleaning liquid. In addition, the heating module 220 is arranged outside the pile body 20 to avoid increasing the external size of the pile body 20, thereby improving the compactness of the pile body 20. Of course, the heating module 220 can also be arranged outside the outer shell of the pile body 20 and suspended, which is not limited by the present disclosure.

[0064] As shown in FIG1 , the liquid supply tank 210 can be disposed within the outer shell of the pile body 20. By designing the outer shell, a space is formed in the outer shell to accommodate the liquid supply tank 210, thereby improving the appearance of the pile body 20 and enhancing the product's competitiveness. Of course, the liquid supply tank 210 can also be disposed outside the outer shell of the pile body 20, and the liquid supply tank 210 can be detachably connected to the outer shell to facilitate the installation, removal, and maintenance of the liquid supply tank 210. This disclosure does not limit this.

[0065] A temperature sensor is provided within the pile body 20. The temperature sensor is configured to detect the temperature of the heated cleaning liquid to determine whether the cleaning liquid has been heated to a preset temperature. One or more temperature sensors may be provided, and providing multiple temperature sensors can increase the accuracy of temperature detection. The temperature sensor and the electric heating module can be connected to the same controller. The controller obtains the temperature of the cleaning liquid in real time to control the heating value of the electric heating module, thereby accurately heating the cleaning liquid to a preset temperature and improving the cleaning effect of the cleaning liquid on the cleaning roller.

[0066] Specifically, the pile body 20 further includes a filter configured to filter the cleaning liquid before it is heated by the heating module 220. The filter can filter the cleaning liquid to prevent impurities in the cleaning liquid from clogging the liquid outlet and affecting the liquid supply to the cleaning roller. The filter can also filter the water quality to prevent the formation of scale.

[0067] The filter is connected between the liquid supply tank 210 and the heating module 220. This means that the cleaning liquid exiting the liquid supply tank 210 is filtered by the filter before being delivered to the heating module 220 for heating, thereby preventing scale from forming when the cleaning liquid is heated. Alternatively, the filter can be placed before the inlet of the liquid supply tank 210. This prevents impurities from entering the liquid supply tank 210 and affecting the quality of the cleaning liquid in the liquid supply tank 210, even if the cleaning liquid passes through the filter before entering the liquid supply tank 210.

[0068] Specifically, the pile body 20 further includes: a nozzle, on which a liquid outlet is formed, and the cleaning liquid can be sprayed onto the cleaning roller through the nozzle.

[0069] The pile body 20 is provided with a liquid spray assembly, which is provided with a liquid spray inlet and multiple liquid outlets. The multiple liquid outlets are arranged in sequence along the axial direction of the cleaning roller 121, so that the cleaning liquid is sprayed at each position along the axial direction of the cleaning roller 121 to improve the wetting effect of the cleaning roller 121. The inlet of the liquid spray assembly is connected to the heating outlet of the heating module 220 through a pipeline. The cleaning liquid at a preset temperature flowing out of the heating outlet of the heating module 220 flows into the liquid spray assembly, and the cleaning liquid at a preset temperature is sprayed on the cleaning roller 121 through the multiple liquid outlets of the liquid spray assembly.

[0070] Among them, a liquid outlet is formed by arranging multiple nozzles on the liquid spraying assembly. By adjusting the shape and size of the nozzle, the coverage area and flow rate of the cleaning liquid sprayed out of the liquid outlet can be changed to improve the effect of spraying the cleaning liquid on the cleaning roller 121; it can be designed according to actual needs, and the present disclosure does not impose any restrictions on this.

[0071] Among them, multiple liquid outlets are located in the roller groove. When the pile body 20 supports the cleaning device 10, the cleaning roller 121 of the cleaning device 10 is accommodated in the roller groove. The multiple liquid outlets are arranged in the roller groove, so that the cleaning liquid sprayed by the liquid outlet is located on the cleaning roller 121, avoiding the waste of cleaning liquid. At the same time, because the cleaning roller 121 and the multiple liquid outlets are all located in the roller groove, the gap between the liquid outlet and the cleaning roller 121 is relatively small, which can improve the wetting effect of the cleaning roller 121. In addition, the groove wall of the roller groove can prevent the cleaning liquid sprayed on the cleaning roller 121 at high speed from splashing back to the periphery of the pile body 20, thereby avoiding the self-cleaning of the cleaning roller 121 affecting the environmental sanitation of the periphery of the pile body 20. In addition, the cleaning liquid sprayed from the liquid outlet can also be sprayed not directly on the cleaning roller 121, but can be sprayed in the roller groove. When the cleaning roller 121 rotates in the roller groove, it is wetted by the cleaning liquid in the roller groove, thereby achieving the cleaning purpose.

[0072] Of course, multiple liquid outlets can be located outside the roller groove, that is, multiple nozzles can be arranged outside the roller groove, and the spraying direction of the multiple nozzles can be directed toward the cleaning roller 121 located in the roller groove, so as to improve the cleaning liquid sprayed by the liquid outlets on the cleaning roller 121 and the wetting effect on the cleaning roller 121. Alternatively, some liquid outlets can be located in the roller groove and some liquid outlets can be located outside the roller groove, forming a double row of liquid outlets to further improve the wetting and cleaning effect on the cleaning roller 121.

[0073] Specifically, the pile body 20 further includes a liquid pump assembly configured to drive the cleaning liquid to spray out through the liquid outlet.

[0074] For example, the pump assembly includes an air pump that can pump air into the liquid supply tank 210 to control the pressure in the liquid supply tank 210. The pump assembly also includes a pressure valve that can pump air into the liquid supply tank 210 to indirectly control the water pressure at the pressure valve, thereby controlling the pressure valve to open and discharge liquid. The pump assembly may also include a pressure relief valve, which is provided on the liquid supply tank 210 and can release the gas pumped into the liquid supply tank 210 by the air pump, thereby reducing the pressure in the liquid supply tank 210 and placing the pressure valve in a closed state. Of course, the air pump can also be used to directly release the gas in the liquid supply tank 210 to reduce the pressure in the liquid supply tank 210.

[0075] For example, the liquid pump assembly includes: a liquid supply pump, which is located between the liquid supply tank 210 and the liquid outlet, and is configured to pump liquid from the cleaning roller in the liquid supply tank 210 to the liquid outlet, so that the cleaning liquid is sprayed out through the liquid outlet.

[0076] Among them, the liquid supply pump is, for example, a peristaltic pump. Since the cleaning liquid is usually an aqueous solution with a cleaning solvent added, it has a certain corrosive effect. When a peristaltic pump is used to supply liquid, the cleaning liquid only needs to contact the pump tube and does not contact the pump body, which will not cause corrosion to the pump body, thereby improving the reliability and life of the liquid supply pump. At the same time, the peristaltic pump has accurate liquid supply, high stability, good sealing, simple maintenance, and no valves and seals. Of course, the liquid supply pump can also be a vane pump, a centrifugal pump, an axial flow pump, etc., and the present disclosure does not limit this.

[0077] The liquid supply pump is located between the liquid supply tank 210 and the heating module 220. This means that the liquid supply pump pumps unheated cleaning liquid, preventing the high temperature cleaning liquid from affecting the performance and life of the liquid supply pump. Of course, the liquid supply pump can also be located after the heating module 220 to pump heated cleaning liquid, and this disclosure is not limited to this.

[0078] Specifically, a cleaning liquid outlet is provided on the pile body 20 , and the cleaning liquid outlet is used to connect with the cleaning device 10 so as to deliver the cleaning liquid to the cleaning device 10 through the cleaning liquid outlet.

[0079] Wherein, the pile body 20 also includes: a control valve, the inlet of the control valve is connected to the outlet of the liquid supply tank 210, and the outlet of the control valve is connected to the liquid outlet and the cleaning liquid outlet; the control valve is configured to connect the outlet of the liquid supply tank 210 with the liquid outlet so as to spray the heated cleaning liquid toward the cleaning roller 121 through the liquid outlet; or, connect the outlet of the liquid supply tank 210 with the cleaning liquid outlet so as to provide the cleaning liquid in the pile body 20 to the cleaning equipment 10, for example, to inject liquid into the clean water tank 111 in the cleaning equipment 10; or, the control valve is configured to connect the outlet of the liquid supply tank 210 with the liquid outlet and the cleaning liquid outlet, that is, to spray the heated cleaning liquid toward the cleaning roller 121 through the liquid outlet and provide the cleaning liquid in the pile body 20 to the cleaning equipment 10 at the same time.

[0080] Specifically, the cleaning device 10 includes a cleaning base 120 and a liquid supply assembly. The cleaning base 120 is equipped with a cleaning roller and a liquid spray port for wetting the cleaning roller. The cleaning base is also equipped with a cleaning liquid inlet, which is connected to the clean water tank 111 in the liquid supply assembly. When the pile body 20 is docked with the cleaning device 10, the cleaning liquid outlet and the cleaning liquid inlet are plugged into each other, that is, liquid can be injected into the clean water tank 111 in the cleaning device 10 through the pile body 20.

[0081] As shown in Figure 1, the handheld floor scrubber also includes an equipment body 110, and a cleaning base 120 is connected to one end of the equipment body 110; a handle assembly 130 is provided on the equipment body 110, and the handle assembly 130 is connected to the end of the equipment body 110 away from the cleaning base 120, for the user to operate and hold. The user controls the cleaning base 120 to move on the surface to be cleaned by holding the handle assembly 130, thereby achieving the purpose of cleaning the surface to be cleaned.

[0082] Among them, the cleaning base 120 is hinged to the device body 110, such as a pivot connection, a ball head connection, etc.; when the user holds the handle assembly to control the cleaning base 120 to move on the surface to be cleaned, by hingedly connecting the cleaning base 120 to the device body 110, the relative angle between the device body 110 and the cleaning base 120 can be adjusted, thereby changing the operating angle and flexibly adjusting the cleaning posture to facilitate the cleaning operation.

[0083] The cleaning base 120 includes a base shell, which includes a top wall, side walls and a bottom wall, and the top wall, side walls and bottom wall enclose a storage space. The cleaning roller 121 is arranged on the bottom wall of the base shell and exposed from the bottom wall, and the bottom surface of the cleaning roller 121 is closer to the surface to be cleaned relative to the bottom wall of the base shell, so that when the cleaning roller 121 contacts the surface to be cleaned, there is a gap between the bottom wall of the base shell and the surface to be cleaned to prevent the base shell from being worn. The number of cleaning rollers 121 is, for example, one, two or more, and the cleaning rollers 121 can rotate at high speed to mop the floor. The cleaning roller 121 can be composed of a rotating shaft and a cleaning cloth wrapped around the surface of the rotating shaft. The rotating shaft rotates at high speed when driven to drive the cleaning surface to rotate at a high speed, thereby performing high-speed rotation and friction cleaning on the surface to be cleaned; the cleaning cloth can be detachably connected to the rotating shaft to facilitate the replacement of the cleaning cloth and improve the maintenance economy of the cleaning roller 121.

[0084] As shown in Figure 1, a first roller 123 is provided at the bottom of the cleaning base 120. The first roller 123 is provided on the side of the bottom of the cleaning base 120 away from the cleaning roller 121. The roller axis of the first roller 123 and the rotating axis of the cleaning roller 121 can be set parallel to each other. By setting the first roller 123, it plays an auxiliary movement role when the user manipulates the cleaning base 120 to move on the surface to be cleaned, thereby avoiding friction between the base shell and the surface to be cleaned; at the same time, a second roller can be provided at the bottom of the cleaning base 120 near the cleaning roller 121. The diameter of the second roller is smaller than that of the first roller 123, which plays a role in assisting the movement of the cleaning base 120 and assisting the rotation of the cleaning roller 121; through the second roller, the base shell near the cleaning roller 121 can be supported, thereby reducing the resistance when the user operates the cleaning base 120 to move.

[0085] The liquid supply assembly includes a clean water tank 111 and a water supply pump. The clean water tank 111 can be fixed to the device body 110. Placing the clean water tank 111 on the device body 110 can, on the one hand, relatively increase the height of the clean water tank 111, making water supply more convenient, and on the other hand, avoid placing it on the cleaning base 120 to increase the size of the cleaning base 120, while also avoiding affecting the difficulty of rotating the cleaning base 120.

[0086] The water supply pump is disposed within the housing of the cleaning base 120, for example, fixed to the bottom wall of the base housing. The water supply pump's inlet can be connected to the clean water tank 111 via a hose to prevent the pipe connecting the water supply pump and the clean water tank 111 from interfering with the rotation of the cleaning base 120 relative to the device body 110 and to prevent the pipe from breaking.

[0087] Among them, the water supply pump is, for example, a peristaltic pump. Since the cleaning liquid is usually an aqueous solution with a cleaning solvent added, it has a certain corrosive effect. When a peristaltic pump is used to supply liquid, the cleaning liquid only needs to contact the pump tube and does not contact the pump body, which will not cause corrosion to the pump body, thereby improving the reliability and life of the water supply pump. At the same time, the peristaltic pump has accurate liquid supply, high stability, good sealing, simple maintenance, and no valves and seals. Of course, the water supply pump can also be a vane pump, a centrifugal pump, an axial flow pump, etc., and the present disclosure does not limit this.

[0088] Wherein, the cleaning base 120 is provided with a liquid spraying port, which is communicated with the liquid outlet of the water supply pump through a pipeline. The cleaning liquid in the clean water tank 111 can be sprayed on the cleaning roller 121 through the liquid spraying port to clean the cleaning roller 121.

[0089] The cleaning liquid inlet can be provided on the bottom wall of the base shell of the cleaning base 120; when the cleaning device 10 is located on the pile body 20, the cleaning liquid inlet faces the pile body 20. The cleaning liquid inlet can be formed by a liquid inlet connector provided on the bottom wall of the base shell to facilitate subsequent connection with other pipelines or interfaces.

[0090] The cleaning liquid inlet is connected to the clean water tank 111 through a pipeline. When the control valve controls the cleaning liquid outlet to discharge liquid, the cleaning liquid in the liquid supply tank 210 is driven by the pump assembly and then flows through the cleaning liquid outlet to the cleaning liquid inlet, so that the cleaning liquid flows to the cleaning device 10.

[0091] Specifically, the cleaning liquid inlet and the cleaning liquid outlet are plugged in. When the scrubber is put back on the pile body 20 after use, the cleaning liquid inlet and the cleaning liquid outlet are plugged in, completing the connection between the cleaning liquid inlet and the cleaning liquid outlet. The user does not need to perform additional operations. The operation is the same as putting a normal scrubber back on the pile body 20 after use. The operation is simple, quick and convenient.

[0092] The cleaning liquid inlet can be located within the cleaning liquid outlet. By locating the cleaning liquid inlet within the cleaning liquid outlet and plugging the cleaning liquid inlet and the cleaning liquid outlet together, the sealing between the two can be improved, thereby preventing leakage at the plugging point. Of course, the cleaning liquid outlet can also be located within the cleaning liquid inlet, and this disclosure does not limit this.

[0093] Furthermore, a sealing member is provided between the cleaning liquid inlet and the cleaning liquid outlet to form a sealed connection when the cleaning liquid inlet and the cleaning liquid outlet are plugged in. The sealing ring can be mounted on the outer circumference of the outlet connector forming the cleaning liquid inlet; alternatively, the sealing ring can be provided on the inner wall of the socket forming the cleaning liquid outlet; alternatively, sealing rings can be provided on both the outer circumference of the outlet connector forming the cleaning liquid inlet and the inner wall of the socket forming the cleaning liquid outlet. The sealing ring can be, for example, a removable rubber ring, which can be easily replaced to improve the sealing effect if the sealing effect of the rubber ring does not meet the requirements.

[0094] In addition, the cleaning liquid inlet and the cleaning liquid outlet can also be connected by magnetic attraction. Magnetic parts are respectively provided on the cleaning liquid inlet and the cleaning liquid outlet. The strong magnetism makes the magnetic parts of the cleaning liquid inlet and the cleaning liquid outlet tightly abut against each other, thereby forming a sealed connection between the cleaning liquid inlet and the cleaning liquid outlet. The magnetic attraction facilitates connection and separation, and simple maintenance. The present disclosure does not impose any restrictions on this. Any changes in the connection method between the cleaning liquid inlet and the cleaning liquid outlet fall within the scope of protection of the present disclosure.

[0095] Specifically, mutually cooperating positioning structures can be provided on the base housing of the cleaning device 10 and the housing of the pile body 20 to assist in locating the floor scrubber in a preset position when it is returned to the pile body 20 after use, thereby improving the reliability of the connection between the heating outlet and the cleaning liquid outlet. The positioning structure can be, for example, a positioning recess provided on the base housing and a positioning protrusion provided on the pile body 20. The positioning protrusion cooperates with the positioning groove to achieve relative positioning of the floor scrubber when it is returned to the pile body 20. Multiple sets of positioning protrusions and positioning grooves can be provided to further enhance the auxiliary positioning function.

[0096] Among them, the positioning structure can also be the first roller 123 at the bottom of the cleaning device 10 and the wheel groove on the pile body 20 to accommodate the first roller 123. The first roller 123 and the wheel groove form the relative positioning of the cleaning device 10 and the pile body 20, thereby improving the stability of the cleaning device 10 on the pile body 20 and achieving the function of auxiliary positioning.

[0097] Specifically, the heating outlet of the heating module 220 can be connected to the liquid spray port and the liquid outlet at the same time, that is, when the floor scrubber is put back on the pile body 20 for self-cleaning after use, the cleaning liquid heated to the preset temperature can be sprayed onto the cleaning roller 121 through the liquid spray port and the liquid outlet at the same time, thereby greatly improving the wetting and cleaning effect of the cleaning roller 121.

[0098] When the heating outlet of the heating module 220 is connected to both the liquid spray port and the liquid outlet, two heating outlets can be provided on the heating module 220 to be connected to the liquid spray port and the liquid outlet respectively, or a single heating outlet provided on the heating module 220 can be used in conjunction with a liquid separator to connect the liquid spray port and the liquid outlet. Check valves can be provided on the pipeline connecting the heating outlet to the liquid spray port and the pipeline connecting the heating outlet to the liquid outlet to prevent backflow of liquid when the pipelines are connected.

[0099] When the heating outlet is connected to the liquid spraying port, a connecting pipe connection structure can be provided on the pile body 20 and the cleaning base 120 to allow cleaning liquid to be sprayed from the pile body 20 to the cleaning base 120 through the liquid spraying port. The pipe connection structure can be the same as the connection structure of the cleaning liquid inlet and cleaning liquid outlet, and will not be described in detail here. Alternatively, the cleaning liquid inlet and cleaning liquid outlet can be coordinated to transport the heated cleaning liquid through the cleaning liquid inlet to the liquid spraying port on the cleaning base 120.

[0100] Specifically, a charging connector is provided on one of the pile body 20 and the cleaning base 120, and a charging interface is provided on the other; when the pile body 20 is docked with the cleaning device 10, the charging connector is electrically connected to the charging interface; wherein, the heating module 220 is an electric heating module, and a power supply module is provided in the pile body 20, and the power supply module is configured to supply power to the charging interface and the electric heating module.

[0101] The floor scrubber may be provided with a charging interface, and the pile body 20 may be provided with a charging connector. When the floor scrubber is placed back on the pile body 20 after use, the charging interface on the floor scrubber is plugged into the charging connector on the pile body 20 to charge the floor scrubber through the pile body 20. That is, the floor scrubber is charged and the cleaning fluid is electrically heated through the pile body 20.

[0102] The pile body 20 is equipped with a power module, which is connected to the charging connector and the electric heating module to power them respectively. This single power module controls the power supply for both the electric heating module and the floor scrubber, eliminating the need for additional components. This reduces costs, improves device integration, and avoids increasing the size of the pile body 20.

[0103] Specifically, as shown in Figure 1 , the cleaning device 10 further includes a sewage tank 112 and a sewage suction channel. The sewage tank 112 is configured to receive sewage, and the sewage suction channel includes a channel inlet 122 and a channel outlet. The channel outlet is connected to the sewage tank 112, and the channel inlet 122 faces the cleaning roller 121 and is located on the side of the scraper near the pile body 20. The sewage suction channel is configured to transport sewage extracted from the cleaning roller 121. The sewage tank 112 can be a negative pressure water tank. A sewage suction fan 113 generates negative pressure, which draws sewage from the cleaning roller 121 and the ground to be cleaned by the scraper through the sewage suction channel into the sewage tank 112.

[0104] When the cleaning device 10 performs self-cleaning on the pile body 20 , the sewage generated by the cleaning can be sucked into the sewage tank 112 through the sewage suction channel.

[0105] The cleaning device 10 further includes a scraper. The scraper is disposed within the base housing and extends axially along the cleaning roller 121. The scraper is configured to scrape liquid, i.e., wastewater, from the cleaning roller 121. The scraper can extend parallel to the axial direction of the cleaning roller 121 to enhance wastewater removal efficiency at various locations along the axial direction of the cleaning roller 121. The scraper draws wastewater from the cleaning roller 121 and the floor to be cleaned through the wastewater suction channel into the wastewater tank 112.

[0106] Among them, when the pile body 20 supports the cleaning device 10, on the circumference of the cleaning roller 121, the angle between the liquid outlet and the scraper is greater than or equal to a preset angle, so that there is a distance between the liquid outlet and the scraper; the preset angle can be 90°, that is, the angle between the liquid outlet and the scraper is, for example, 90°, 100°, 110°, 120°, 130°, 150°, 160°, 170°, 180°, etc., which are not listed here one by one. By making the angle between the liquid outlet and the scraper greater than or equal to 90° on the circumference of the cleaning roller 121, there is sufficient distance between the liquid outlet and the scraper, so that the cleaning liquid can fully wet the cleaning cloth on the cleaning roller 121, thereby improving the self-cleaning effect of the cleaning roller 121; at the same time, there is a certain distance between the liquid outlet and the channel inlet of the sewage suction channel, so as to prevent the cleaning liquid sprayed from the liquid outlet from being directly sucked into the sewage suction channel.

[0107] Specifically, a sewage outlet can be provided on the pile body 20, and the sewage outlet is located near the cleaning roller 121. The sewage outlet is configured to discharge sewage after cleaning the cleaning roller 121. The sewage cleaned by the cleaning roller 121 is directly discharged through the pile body 20, thereby avoiding the sewage from returning to the sewage phase of the cleaning device 10, facilitating use, reducing maintenance of the cleaning device 10, and reducing power consumption of the cleaning device 10, thereby improving the endurance and economical practicality of the cleaning device 10.

[0108] Wherein, the sewage outlet can be provided with a valve to control the opening and closing of the sewage outlet. The valve can be a solenoid valve, that is, the sewage outlet can be closed by an operator or an automatic system operation.

[0109] Specifically, the pile body 20 also includes: a drying module 230, which is configured to provide airflow; an air outlet of the drying module 230 is provided on the shell of the pile body 20, and the drying module 230 outputs airflow from the air outlet through a drying air duct to dry the cleaning roller 121; the airflow output by the drying module 230 through the air outlet can be normal temperature airflow or heated airflow, and the use of heated airflow is more conducive to the drying of the cleaning roller 121.

[0110] Among them, the air outlet is located outside the roller groove; after the cleaning roller 121 completes cleaning on the pile body 20, it needs to be dried. By locating the air outlet outside the roller groove, the circulation of the air flow can be improved, thereby improving the drying effect of the cleaning cloth on the cleaning roller 121, improving the air drying efficiency, reducing the power consumption required for drying, and improving the product energy efficiency ratio; at the same time, it can prevent the cleaning liquid sprayed from the liquid outlet from entering the air outlet.

[0111] Of course, the air outlet of drying module 230 can also be located within the roller groove. When the liquid outlet is located within the roller groove, the air outlet is located on the side of the roller groove near the roller groove opening relative to the liquid outlet. This prevents cleaning liquid sprayed from the liquid outlet from entering the air outlet. Furthermore, the air outlet of drying module 230 can be located both outside and inside the roller groove, that is, drying module 230 has multiple air outlets.
