DETAILED DESCRIPTION

[0089] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0090] Although relative terms such as "upper" and "lower" are used in this specification to describe the relationship of one illustrated component to another, these terms are used herein for convenience only, such as in accordance with the orientation of the illustrations in the accompanying drawings. It will be understood that if the illustrated device were flipped upside down, the component described as "upper" would become the component "lower." When a structure is referred to as "on" another structure, this may mean that the structure is integrally formed with the other structure, that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure via the other structure.

[0091] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.; the terms "first", "second", etc. are used only as labels and are not intended to limit the quantity of their objects.

[0092] In the related art, cleaning equipment, such as a floor scrubber, typically includes a clean water tank that supplies cleaning fluid to the cleaning head while mopping the floor. After use, the floor scrubber is typically returned to its base, supported by the base. Self-cleaning of the equipment, such as automatic cleaning of the cleaning head, can be performed on the base. The cleaning head can be, for example, a cleaning roller with a strip-shaped cleaning surface, a cleaning brush with a circular cleaning surface, or a cleaning disc.

[0093] However, in order to automatically clean the cleaning head through the pile body, a water tank is usually provided in the pile body to accommodate the cleaning liquid for automatic cleaning of the cleaning roller. The provision of the water tank increases the volume of the pile body, resulting in increased costs. At the same time, in addition to maintaining the water tank on the floor scrubber, the user also needs to maintain an additional water tank, which causes inconvenience to the user and affects the market competitiveness of the product.

[0094] 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.

[0095] It should be noted that the "nozzle" described in this article can be used to spray liquid media, such as cleaning fluid, etc.; it can also be used to spray gaseous media, such as steam, hot air, etc.

[0096] 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, and the cleaning head is a cleaning roller.

[0097] As shown in Figures 1 and 2, the handheld floor scrubber includes a cleaning base 120 and a liquid supply assembly. The cleaning base 120 is provided with a cleaning head, a liquid outlet 127 to be heated, and a first nozzle 1262 for cleaning the cleaning head. The liquid supply assembly is configured to supply liquid to at least one of the first nozzle 1262 and the liquid outlet 127 to be heated; the pile body 20 is provided with a liquid inlet 240 to be heated for communicating with the liquid outlet 127 to be heated, and the pile body 20 is configured to heat the cleaning liquid entering the liquid inlet 240 to be heated; the pile body 20 is provided with a second nozzle 221 for cleaning the cleaning head. After being heated, the cleaning liquid can be sprayed out through the second nozzle 221, or through the first nozzle 1262, or through the first nozzle 1262 and the second nozzle 221 at the same time.

[0098] Specifically, as shown in Figures 1 and 2, 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 operation by a user. By holding the handle assembly 130, the user controls the cleaning base 120 to move on the surface to be cleaned, thereby achieving the purpose of cleaning the surface to be cleaned.

[0099] 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 130 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.

[0100] As shown in Figures 3, 9, and 11, the cleaning base 120 includes a base housing 1201, which includes a top wall, side walls, and a bottom wall, which together form a storage space. A cleaning roller 121 is disposed on the bottom wall of the base housing 1201, protruding from the bottom wall. The bottom surface of the cleaning roller 121 is closer to the surface to be cleaned than the bottom wall of the base housing 1201, so that when the cleaning roller 121 contacts the surface to be cleaned, a gap is provided between the bottom wall of the base housing 1201 and the surface to be cleaned, thereby preventing wear on the base housing 1201. The number of cleaning rollers 121 can be, 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 comprise a rotating shaft and a cleaning cloth wrapped around the shaft. The rotating shaft rotates at high speed when driven, causing the cleaning surface to rotate at high speed, thereby performing high-speed rotational friction cleaning on the surface to be cleaned. The cleaning cloth can be detachably connected to the rotating shaft, facilitating replacement of the cleaning cloth and improving the maintenance efficiency of the cleaning roller 121.

[0101] As shown in Figure 9, a first roller 1291 is provided at the bottom of the cleaning base 120. The first roller 1291 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 1291 and the rotating axis of the cleaning roller 121 can be set parallel to each other. By setting the first roller 1291, 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 1201 and the surface to be cleaned; at the same time, a second roller 1292 can be provided at the bottom of the cleaning base 120 near the cleaning roller 121. The diameter of the second roller 1292 is smaller than that of the first roller 1291, and it 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 1292, the base shell 1201 near the cleaning roller 121 can be supported, thereby reducing the resistance when the user operates the cleaning base 120 to move.

[0102] Specifically, the liquid supply component includes a first liquid outlet and a second liquid outlet, and the liquid supply component is configured to control the liquid discharge of at least one of the first liquid outlet and the second liquid outlet, that is, only the first liquid outlet discharges liquid, or only the second liquid outlet discharges liquid, or the first liquid outlet and the second liquid outlet discharge liquid at the same time.

[0103] In some embodiments, as shown in Figures 2 and 6, the liquid supply assembly includes a liquid supply tank 140, a liquid supply pump 124, and a liquid dispensing controller 125. The liquid supply tank 140 can be fixed to the device body 110. Placing the liquid supply tank 140 on the device body 110 can, on the one hand, relatively increase the height of the liquid supply tank 140, making water supply more convenient, and on the other hand, avoid increasing the size of the cleaning base 120 by placing it on the cleaning base 120, while also avoiding affecting the difficulty of rotating the cleaning base 120.

[0104] As shown in Figures 6 and 7, the liquid supply pump 124 is disposed within the accommodation space of the base housing 1201 of the cleaning base 120, for example, fixed to the bottom wall of the base housing 1201. The inlet 1241 of the liquid supply pump 124 can be connected to the liquid supply tank 140 via a hose, so as to prevent the pipe connecting the liquid supply pump 124 and the liquid supply tank 140 from affecting the rotation of the cleaning base 120 relative to the device body 110 and to prevent the pipe from breaking.

[0105] Among them, the liquid supply pump 124 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 124. 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 124 can also be a vane pump, a centrifugal pump, an axial flow pump, etc., and the present disclosure does not limit this.

[0106] The cleaning liquid in the liquid supply tank 140 may also be water or a solution of water and detergent, which is not limited in the present disclosure, as long as it can achieve a cleaning effect on the cleaning roller 121 .

[0107] As shown in Figures 6 and 7, the liquid separation controller 125 is disposed in the accommodation space of the base housing 1201 of the cleaning base 120, for example, fixed to the bottom wall of the base housing 1201, and spaced apart from the liquid supply pump 124. The liquid separation controller 125 includes a controller liquid inlet 1251, a first liquid outlet 1252, and a second liquid outlet 1253. The controller liquid inlet 1251 is connected to the outlet 1242 of the liquid supply pump 124. The liquid separation controller 125 is configured to control the first liquid outlet 1252 to discharge liquid, the second liquid outlet 1253 to discharge liquid, or the first liquid outlet 1252 to discharge liquid and the second liquid outlet 1253 to discharge liquid simultaneously when the liquid separation controller 125 is in the open state. When the liquid separation controller 125 is in the closed state, neither the first liquid outlet 1252 nor the second liquid outlet 1253 discharges liquid.

[0108] The liquid dispensing controller 125 may include an electrically controlled liquid dispenser, such as a solenoid valve. By configuring the solenoid valve, the controller may be used to control the flow direction of the cleaning liquid, and may also be used to control the flow rate, flow velocity, etc. The liquid dispensing controller 125 may also include a mechanical liquid dispenser, such as a mechanical valve. After the user places the cleaning device 10 on the pile body 20, the user may set a mechanical switch on the cleaning device 10 to control the flow direction of the mechanical liquid dispenser, thereby controlling the discharge of liquid from the first liquid outlet 1252 and / or controlling the discharge of liquid from the second liquid outlet 1253.

[0109] 8 , the cleaning base 120 is provided with a first nozzle 1262 , which is connected to the first liquid outlet 1252 of the liquid separation controller 125 via a pipeline. The cleaning liquid can be sprayed onto the cleaning roller 121 through the first nozzle 1262 to clean the cleaning roller 121 .

[0110] As shown in Figures 9 and 10, the cleaning base 120 is provided with a heated liquid outlet 127, which can be provided on the bottom wall of the base shell 1201 of the cleaning base 120. When the cleaning device 10 is positioned on the pile body 20, the heated liquid outlet 127 faces the pile body 20. The heated liquid outlet 127 can be formed by a liquid outlet connector provided on the bottom wall of the base shell 1201 to facilitate subsequent connection with other pipelines or interfaces.

[0111] The liquid outlet 127 to be heated is connected to the second liquid outlet 1253 of the liquid separation controller 125 via a pipeline. When the liquid separation controller 125 controls the second liquid outlet 1253 to discharge liquid, the cleaning liquid in the liquid supply tank 140 is driven by the liquid supply pump 124 and then flows through the second liquid outlet 1253 of the liquid separation controller 125 to the liquid outlet 127 to be heated, so that the cleaning liquid flows to the pile body 20.

[0112] The cleaning device 10 provided in the present disclosure controls the liquid supply component to discharge liquid from the second liquid outlet 1253, and then drains the liquid through the heated liquid outlet 127, thereby facilitating the discharge of excess cleaning liquid in the liquid supply tank 140 without the user having to disassemble the liquid supply tank 140, thereby improving the drainage convenience of the liquid supply tank 140 and thus improving the ease of use of the cleaning device 10.

[0113] Specifically, as shown in Figures 11 to 16 , the pile body 20 includes a housing 200 and a heating module 260. The housing 200 is formed with a heated liquid inlet 240 and a receiving groove, i.e., a roller groove 210, for accommodating the cleaning roller 121. When the pile body 20 supports the cleaning device 10, the heated liquid inlet 240 communicates with the heated liquid outlet 127. The heating module 260 may be an electric heating module.

[0114] As shown in Figures 15 and 16, the heating module 260 includes a heating inlet 2610 and a heating outlet 2620. The heating inlet 2610 is connected to the liquid inlet 240 to be heated through a pipeline, so that when the liquid separation controller 125 controls the second liquid outlet 1253 to discharge liquid, the cleaning liquid in the liquid supply tank 140 is driven by the liquid supply pump 124, and then flows to the liquid outlet 127 to be heated through the liquid separation controller 125, enters the liquid inlet 240 to be heated, and then enters the accommodating cavity of the heating module 260; then the heating module 260 is The configuration heats the liquid entering the receiving cavity of the heating module 260 to a preset temperature, which may be, for example, 40° to 60°, such as 40°, 45°, 50°, 55°, 60°, etc., which are not listed one by one in the present disclosure. By heating the cleaning liquid to 40° to 60°, the activity of the cleaning liquid can be improved, thereby improving the cleaning effect of the cleaning liquid, while also avoiding the influence of excessive temperature on the activity of the cleaning liquid. Of course, the preset temperature may also be less than 40° or greater than 60°, which is not limited in the present disclosure.

[0115] As shown in Figure 13, the shell 200 is provided with a second nozzle 221 for spraying liquid onto the cleaning roller 121. The second nozzle 221 is connected to the heating outlet 2620 of the heating module 260 through a pipeline, so that the cleaning liquid heated to a preset temperature by the heating module 260 is sprayed onto the cleaning roller 121; the cleaning liquid with a higher temperature can improve the cleaning effect of the cleaning roller 121.

[0116] Among them, the second nozzle 221 can be set toward the cleaning roller 121, that is, the second nozzle 221 can spray the cleaning liquid directly onto the cleaning roller 121; or, the second nozzle 221 can spray the cleaning liquid near the cleaning roller 121, and the cleaning liquid is splashed onto the cleaning roller 121 or flows onto the cleaning roller 121 through other structural parts. The present disclosure does not impose any restrictions on this, and it is sufficient that the cleaning roller 121 can be cleaned by the cleaning liquid.

[0117] When the first liquid outlet 1252 and the second liquid outlet 1253 discharge liquid at the same time, the first nozzle 1262 and the second nozzle 221 can spray the cleaning liquid onto the cleaning roller 121 at the same time to improve the cleaning effect of the cleaning roller 121 .

[0118] Thus, by cooperating between the liquid supply tank 140 and the liquid separation controller 125 on the cleaning equipment 10, and the heating module 260 and the second nozzle 221 on the pile body 20, the purpose of spraying cleaning liquid of a preset temperature on the cleaning roller 121 is achieved; the cooperation between the liquid supply tank 140 and the liquid separation controller 125 realizes the use of two-way liquid supply using one liquid supply tank 140, thereby avoiding the need to set up another liquid supply tank separately in the pile body 20, avoiding the increase in the volume of the pile body 20 due to self-cleaning of the cleaning roller 121 by the pile body 20, and reducing the cost of the pile body 20; at the same time, the user only needs to maintain one liquid supply tank on the floor scrubber, which is more convenient for the user to use and improves the market competitiveness of the product.

[0119] In some embodiments, as shown in Figure 17, the liquid supply component includes: a liquid supply tank 140, a liquid supply pump 124 and a control valve 160; the inlet of the liquid supply pump 124 is connected to the liquid supply tank 140, and the control valve 160 includes a control valve liquid inlet and a control valve liquid outlet, and the control valve liquid inlet is connected to the outlet of the liquid supply pump 124.

[0120] As shown in FIG8 , a first nozzle 1262 is provided on the cleaning base 120 , and cleaning liquid can be sprayed onto the cleaning roller 121 through the first nozzle 1262 to clean the cleaning roller 121 .

[0121] As shown in Figures 9 and 10, the cleaning base 120 is provided with a heated liquid outlet 127, which can be provided on the bottom wall of the base shell 1201 of the cleaning base 120. When the cleaning device 10 is positioned on the pile body 20, the heated liquid outlet 127 faces the pile body 20. The heated liquid outlet 127 can be formed by a liquid outlet joint provided on the bottom wall of the base shell 1201 to facilitate subsequent connection with other pipelines or interfaces.

[0122] The first nozzle 1262 is directly connected to the outlet 1242 of the liquid supply pump 124 , and the liquid outlet of the control valve is connected to the liquid outlet 127 to be heated.

[0123] 11 to 16 , a heated liquid inlet 240 and a roller groove 210 for accommodating the cleaning roller 121 are formed on the shell 200 of the pile body 20 ; when the pile body 20 supports the cleaning device 10 , the heated liquid inlet 240 is connected to the heated liquid outlet 127 .

[0124] As shown in Figures 15 and 16, the heating module 260 includes a heating inlet 2610 and a heating outlet 2620. The heating inlet 2610 is connected to the liquid inlet 240 to be heated through a pipeline, so that when the liquid separation controller 125 controls the second liquid outlet 1253 to discharge liquid, the cleaning liquid in the liquid supply tank 140 is driven by the liquid supply pump 124, and then flows through the liquid separation controller 125 to the liquid outlet 127 to be heated, enters the liquid inlet 240 to be heated, and then enters the accommodating cavity of the heating module 260; then the heating module 260 is configured to heat the liquid entering the accommodating cavity of the heating module 260, and heats it to a preset temperature, the preset temperature is, for example, 40°~60°.

[0125] As shown in Figure 13, the shell 200 is provided with a second nozzle 221 for spraying liquid onto the cleaning roller 121. The second nozzle 221 is connected to the heating outlet 2620 of the heating module 260 through a pipeline, so that the cleaning liquid heated to a preset temperature by the heating module 260 is sprayed onto the cleaning roller 121; the cleaning liquid with a higher temperature can improve the cleaning effect of the cleaning roller 121.

[0126] When the liquid outlet of the control valve 160 is connected to the liquid outlet to be heated 127, the liquid supply assembly can control the liquid outlet to be heated 127 and the first nozzle 1262 to discharge liquid simultaneously, that is, start the liquid supply pump 124 and open the control valve 160; or, the liquid supply assembly can control only the first nozzle 1262 to discharge liquid, that is, start the liquid supply pump 124 and close the control valve 160. By controlling the liquid outlet to be heated 127 and the first nozzle 1262 to discharge liquid simultaneously, the cleaning liquid can be sprayed onto the cleaning roller 121 through the first nozzle 1262 and the second nozzle 221 at the same time, thereby improving the cleaning effect of the cleaning roller 121.

[0127] Thus, by cooperating with the liquid supply tank 140 and the control valve 160 on the cleaning equipment 10, and the heating module 260 and the second nozzle 221 on the pile body 20, the purpose of spraying cleaning liquid of a preset temperature on the cleaning roller 121 is achieved; the liquid supply tank 140, the liquid supply pump 124 and the control valve 160 cooperate to realize two-way liquid supply using one liquid supply tank 140, thereby avoiding the need to set up another liquid supply tank separately in the pile body 20, avoiding the increase in the volume of the pile body 20 due to self-cleaning of the cleaning roller 121 by the pile body 20, and reducing the cost of the pile body 20; at the same time, the user only needs to maintain one liquid supply tank on the floor scrubber, which is more convenient for the user to use and improves the market competitiveness of the product.

The pressure supply component 171 is connected to the liquid supply box 140, and the pressure valve 172 is arranged between the liquid inlet of the liquid separation controller 125 and the outlet of the liquid supply box 140.

[0129] The pressure valve 172 is closed when the pressure in the liquid supply tank 140 is less than a preset pressure value, and is opened when the pressure in the liquid supply tank 140 is greater than or equal to the preset pressure value via the pressure supply assembly 171. The preset pressure value can be set as needed and is not limited in this disclosure.

[0130] The pressure supply assembly 171 includes an air pump that pumps air into the liquid supply tank 140 to control the pressure in the liquid supply tank 140, thereby indirectly controlling the water pressure at the pressure valve 172. The pressure supply assembly 171 also includes a pressure relief valve, which is provided on the liquid supply tank 140 and can release the air pumped into the liquid supply tank 140, thereby reducing the pressure in the liquid supply tank 140 and placing the pressure valve 172 in a closed state.

[0133] The liquid dispensing controller 125 can be disposed in the accommodation space of the base housing 1201 of the cleaning base 120, for example, fixed to the bottom wall of the base housing 1201. The liquid dispensing controller 125 includes a controller liquid inlet, a first liquid outlet, and a second liquid outlet. The controller liquid inlet is connected to the outlet of the pressure valve. When the liquid dispensing controller 125 is in an open state, it can control liquid discharge from the first liquid outlet, liquid discharge from the second liquid outlet, or liquid discharge from both the first and second liquid outlets. When the liquid dispensing controller 125 is in a closed state, neither the first liquid outlet nor the second liquid outlet discharges liquid.

[0134] The first liquid outlet of the liquid separation controller 125 is connected to the first nozzle 1262 , and the second liquid outlet is connected to the liquid outlet 127 to be heated.

[0135] The liquid separation controller 125 may include an electronically controlled liquid separator, such as a solenoid valve. By configuring the solenoid valve, the controller may be used to control the flow direction of the cleaning liquid, and may also be used to control the flow rate, flow rate, etc. The liquid separation controller 125 may also include a mechanical liquid separator, such as a mechanical valve. After the user places the cleaning device 10 on the pile body 20, the user may set a mechanical switch on the cleaning device 10 to control the flow direction of the mechanical liquid separator, thereby controlling the discharge of liquid from the first liquid outlet and / or controlling the discharge of liquid from the second liquid outlet.

[0142] The pressure supply assembly 171 includes an air pump that pumps air into the liquid supply tank 140 to control the pressure in the liquid supply tank 140, thereby indirectly controlling the water pressure at the pressure valve 172. The pressure supply assembly 171 also includes a pressure relief valve, which is provided on the liquid supply tank 140 and can release the air pumped into the liquid supply tank 140, thereby reducing the pressure in the liquid supply tank 140 and placing the pressure valve 172 in a closed state. Of course, the air pump can also be used to directly release the air in the liquid supply tank 140 to reduce the pressure in the liquid supply tank 140.

[0150] In some embodiments, as shown in FIG. 20 , the liquid supply assembly includes: a liquid supply tank 140 , a first liquid supply pump 181 and a second liquid supply pump 182 , and the inlets of the first liquid supply pump 181 and the second liquid supply pump 182 are both connected to the outlet of the liquid supply tank 140 .

[0151] 8 , the cleaning base 120 is provided with a first nozzle 1262 , which is connected to the outlet of the first liquid supply pump 181 via a pipeline. The cleaning liquid can be sprayed onto the cleaning roller 121 through the first nozzle 1262 to clean the cleaning roller 121 .

[0152] As shown in Figures 9 and 10, the cleaning base 120 is provided with a heated liquid outlet 127, which can be located on the bottom wall of the base housing 1201 of the cleaning base 120. When the cleaning device 10 is positioned on the pile body 20, the heated liquid outlet 127 faces the pile body 20.

The outlet of the second liquid supply pump 182 is connected to the heated liquid outlet.

[0153] The heated liquid outlet 127 is connected to the outlet of the second liquid supply pump 182 via a pipeline. When the second liquid supply pump 182 discharges liquid, the cleaning liquid in the liquid supply tank 140 flows to the heated liquid outlet 127 driven by the second liquid supply pump 182, so that the cleaning liquid flows to the heating module.

[0157] Among them, the first liquid supply pump 181 and the second liquid supply pump 182 are, for example, peristaltic pumps. 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 first liquid supply pump 181 and the second liquid supply pump 182. At the same time, the peristaltic pump has accurate liquid supply, high stability, good sealing, simple maintenance, and no valves and seals.

The inlet of the second liquid supply pump 182 in the pile body 20 is connected to the liquid inlet 240 to be heated. The cleaning liquid in the liquid supply tank 140 can be pumped into the pile body 20 by the second liquid supply pump 182.

[0162] Among them, a pressure valve 172 is provided between the liquid supply tank 140 and the liquid outlet 127 to be heated; when the floor scrubber is not placed on the pile body, the pressure valve 172 is in a closed state; when the floor scrubber is placed on the pile body 20, and the pressure valve 172 is in a closed state when the liquid pumping pressure provided by the second liquid supply pump 182 is less than the preset pressure value, the pressure valve 172 is in a closed state, and when the liquid pumping pressure provided by the second liquid supply pump 182 is greater than or equal to the preset pressure value, the pressure valve 172 is in an open state; the preset pressure value can be set as needed, and the present disclosure does not limit it here.

[0163] As shown in Figures 11 to 16, the pile body 20 includes a shell 200 and a heating module 260. The heating module 260 includes a heating inlet 2610 and a heating outlet 2620. The heating inlet 2610 is connected to the liquid inlet 240 to be heated through a pipeline. The second liquid supply pump 182 is located between the heating inlet 2610 and the liquid inlet 240 to be heated. When the second liquid supply pump 182 draws the cleaning liquid from the liquid supply tank 140 to the heating module, the cleaning liquid enters the accommodating cavity of the heating module 260; then the heating module 260 is configured to heat the liquid entering the accommodating cavity of the heating module 260 and heat it to a preset temperature, the preset temperature being, for example, 40° to 60°.

[0164] The second liquid supply pump 182 may also be located between the heating outlet 2620 and the second nozzle 221 , so as to open the pressure valve 172 to extract the cleaning liquid from the liquid supply tank 140 .

[0165] Among them, when the first liquid supply pump 181 discharges liquid, the first nozzle 1262 sprays the cleaning liquid on the cleaning roller 121; when the second liquid supply pump 182 discharges liquid, the second nozzle 221 sprays the cleaning liquid on the cleaning roller 121; when the first liquid supply pump 181 and the second liquid supply pump 182 discharge liquid at the same time, the first nozzle 1262 and the second nozzle 221 can spray the cleaning liquid on the cleaning roller 121 at the same time to improve the cleaning effect of the cleaning roller 121.

[0166] Among them, the first liquid supply pump 181 and the second liquid supply pump 182 are, for example, peristaltic pumps. 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 first liquid supply pump 181 and the second liquid supply pump 182. 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 first liquid supply pump 181 and the second liquid supply pump 182 can also be vane pumps, centrifugal pumps, axial flow pumps, etc., and the present disclosure does not limit this.

[0167] In some embodiments, as shown in FIG15 , the housing 200 of the pile body 20 is formed with a storage space, and the heating module 260 is housed in the storage space. The heating module 260 is relatively small and occupies less space. The heating module 260 includes a heating module housing, a heating inlet 2610 and a heating outlet 2620 disposed on the heating module housing. The housing of the heating module 260 forms a storage chamber, and an electric heating wire or electric heating column is disposed in the storage chamber to heat the liquid flowing through the storage chamber. The storage chamber may also be provided with a flow channel, and the heating inlet 2610 and the heating outlet 2620 are disposed at the inlet and outlet of the flow channel to guide the flow of cleaning liquid in the storage chamber, thereby improving the heating efficiency of the cleaning liquid. Alternatively, the cleaning liquid does not enter the heating module 260, and the heating module 260 is disposed near the pipeline transporting the cleaning liquid, thereby generating heat to increase the temperature of the pipeline transporting the cleaning liquid, thereby achieving the purpose of heating the cleaning liquid in the pipeline.

[0168] In some embodiments, the heating module 260 can heat the cleaning liquid in the cleaning base 120 without directing the cleaning liquid into the pile body 20 for heating.

[0169] Among them, the heating module 260 can be set on the pile body 20 near the supporting surface of the cleaning base 120; the pipeline used by the cleaning base 120 to transport the cleaning liquid to the first nozzle 1262 is set at the bottom of the cleaning base 120, that is, when the cleaning base 120 is located on the pile body 20, the heating module 260 is set adjacent to the pipeline for transporting the cleaning liquid. The heat generated by the heating module 260 can heat the cleaning liquid in the pipeline, so that the first nozzle 1262 sprays out the cleaning liquid of the preset temperature to improve the cleaning effect.

[0170] In this case, the pile body 20 does not need to be provided with the liquid inlet 240 to be heated and the second nozzle 221 , thereby reducing the production cost of the pile body 20 .

[0171] Of course, the cleaning liquid heated in the cleaning base 120 can also enter the pile body 20 through the liquid inlet 240 to be heated on the pile body 20 , and then be sprayed out through the second nozzle 221 on the pile body 20 .

[0172] The heating module 260 can be exposed from the housing 200 of the pile body 20 to enhance the heating effect on the cleaning liquid in the cleaning base 120. The pipeline for transporting the cleaning liquid in the cleaning base 120 can also be exposed from the base housing 1201 of the cleaning base 120 to enhance the heating effect on the cleaning liquid. Of course, the heating module 260 and the pipeline for transporting the cleaning liquid can also be arranged without being exposed, and this disclosure does not limit this.

[0173] When a liquid supply pump is provided in the pile body 20, the liquid supply pump can draw the heated cleaning liquid into the pile body 20 through the liquid inlet 240 to be heated, and then spray it out through the second nozzle 221. The inlet of the liquid supply pump is connected to the liquid inlet 240 to be heated, and the outlet of the liquid supply pump is connected to the heating inlet of the heating module 260; alternatively, the inlet of the liquid supply pump is connected to the heating outlet of the heating module 260, and the heated cleaning liquid is output through the outlet of the liquid supply pump.

[0174] In some embodiments, as shown in Figures 6 to 8, a first liquid spray assembly is provided on the cleaning base 120. The first liquid spray assembly is provided with a first liquid spray inlet 1261 and a plurality of first nozzles 1262. The first liquid spray inlet 1261 is in communication with the plurality of first nozzles 1262. Cleaning liquid is delivered to the first liquid spray assembly through the first liquid spray inlet 1261, and is then sprayed out through the plurality of first nozzles 1262. The plurality of first nozzles 1262 are arranged in sequence along the axial direction of the cleaning roller 121, spraying the cleaning liquid at each position along the axial direction of the cleaning roller 121, thereby improving the wetting effect on the cleaning roller 121.

[0175] In some embodiments, as shown in Figures 13 and 14, a second liquid spraying assembly 220 is provided on the pile body 20. The second liquid spraying assembly 220 is provided with a second liquid spraying inlet 222 and a plurality of second nozzles 221. The plurality of second nozzles 221 are arranged in sequence along the axial direction of the cleaning roller 121, and the cleaning liquid is sprayed on each position in the axial direction of the cleaning roller 121 to improve the wetting effect on the cleaning roller 121. The inlet of the second liquid spraying assembly 220 is connected to the heating outlet 2620 of the heating module 260 through a pipeline. The cleaning liquid at a preset temperature flowing out of the heating outlet 2620 of the heating module 260 flows into the second liquid spraying assembly 220, and the cleaning liquid at a preset temperature is sprayed on the cleaning roller 121 through the plurality of second nozzles 221 of the second liquid spraying assembly 220.

[0176] Among them, the second liquid spraying assembly 220 is provided with a plurality of nozzles to form a second nozzle 221. By adjusting the nozzle shape and size of the nozzle, the coverage area and flow rate of the cleaning liquid sprayed out by the second nozzle 221 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.

[0177] As shown in FIG13 , a plurality of second nozzles 221 are located in the roller groove 210. 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 210. The plurality of second nozzles 221 are arranged in the roller groove 210 so that the cleaning liquid sprayed by the second nozzles 221 is located on the cleaning roller 121, thereby avoiding waste of the cleaning liquid. At the same time, since the cleaning roller 121 and the plurality of second nozzles 221 are all located in the roller groove 210, the gap between the second nozzles 221 and the cleaning roller 121 is relatively small, thereby improving the wetting effect of the cleaning roller 121. In addition, the groove wall of the roller groove 210 can prevent the cleaning liquid sprayed at high speed onto the cleaning roller 121 from splashing back to the periphery of the pile body 20, thereby avoiding the environmental sanitation of the periphery of the pile body 20 affected by the self-cleaning of the cleaning roller 121.

[0178] Of course, the plurality of second nozzles 221 can be located outside the roller groove 210, that is, the plurality of nozzles can be arranged outside the roller groove 210, and the spraying direction of the plurality of nozzles can be directed toward the cleaning roller 121 located in the roller groove 210, so as to improve the cleaning liquid sprayed by the second nozzles 221 and the wetting effect on the cleaning roller 121. Alternatively, some of the second nozzles 221 can be located in the roller groove 210, and some of the second nozzles 221 can be located outside the roller groove 210, forming a double row of nozzles, so as to further improve the wetting and cleaning effect on the cleaning roller 121.

[0179] In some embodiments, as shown in Figures 9 to 12 , the heated liquid outlet 127 is plugged into the heated liquid inlet 240. When the scrubber is returned to the pile body 20 after use, the heated liquid outlet 127 and the heated liquid inlet 240 are plugged into each other, completing the connection between the heated liquid outlet 127 and the heated liquid inlet 240. This connection is simple, quick, and convenient, requiring no additional user intervention. This is similar to placing a normal scrubber back onto the pile body 20 after use.

[0180] The heated liquid outlet 127 can be located within the heated liquid inlet 240. By locating the heated liquid outlet 127 within the heated liquid inlet 240, the heated liquid outlet 127 and the heated liquid inlet 240 can be plugged together, thereby improving the sealing performance of the plug-in connection between the heated liquid outlet 127 and the heated liquid inlet 240 and preventing leakage at the plug-in connection. Of course, the heated liquid inlet 240 can also be located within the heated liquid outlet 127, and this is not a limitation of the present disclosure.

[0181] Furthermore, a sealing member is provided between the liquid outlet 127 to be heated and the liquid inlet 240 to be heated, so as to form a sealed connection after the liquid outlet 127 to be heated and the liquid inlet 240 to be heated are plugged in. The sealing ring can be sleeved on the outer peripheral surface of the liquid outlet joint forming the liquid outlet 127 to be heated; or, the sealing ring can be provided on the inner wall of the socket forming the liquid inlet 240 to be heated; or, the sealing ring can be provided on both the outer peripheral surface of the liquid outlet joint forming the liquid outlet 127 to be heated and the inner wall of the socket forming the liquid inlet 240 to be heated. The sealing ring can be, for example, a rubber ring that is detachable and can be easily replaced when the sealing effect of the rubber ring does not meet the requirements, thereby improving the sealing effect.

[0182] In addition, the liquid outlet 127 to be heated and the liquid inlet 240 to be heated can also be connected by magnetic attraction. Magnetic parts are respectively provided on the liquid outlet 127 to be heated and the liquid inlet 240 to be heated. The strong magnetism makes the magnetic parts of the liquid outlet 127 to be heated and the liquid inlet 240 to be heated tightly abut against each other, thereby forming a sealed connection between the liquid outlet 127 to be heated and the liquid inlet 240 to be heated. 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 liquid outlet 127 to be heated and the liquid inlet 240 to be heated fall within the scope of protection of the present disclosure.

[0183] In some embodiments, mutually cooperating positioning structures can be provided on the base housing 1201 of the cleaning device 10 and the housing 200 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 heated liquid outlet and the heated liquid inlet 240. The positioning structure can be, for example, a positioning recess provided on the base housing 1201 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.

[0184] Among them, the positioning structure can also be a roller at the bottom of the cleaning device 10 and a wheel groove on the pile body 20 to accommodate the roller. The roller 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.

[0185] In some embodiments, the heating outlet 2620 of the heating module can be connected to the first liquid spray inlet 1261 and the second nozzle 221 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 first nozzle 1262 and the second nozzle 221 at the same time, thereby greatly improving the wetting and cleaning effect of the cleaning roller 121.

[0186] When the heating outlet 2620 of the heating module is connected to both the first liquid spray inlet 1261 and the second nozzle 221, two heating outlets 2620 may be provided on the heating module to be connected to the first liquid spray inlet 1261 and the second nozzle 221, respectively. Alternatively, one heating outlet 2620 provided on the heating module may be used in conjunction with a liquid separator to achieve connection with the first liquid spray inlet 1261 and the second nozzle 221. Check valves may be provided on the pipeline connecting the heating outlet 2620 to the first liquid spray inlet 1261 and on the pipeline connecting the heating outlet 2620 to the second nozzle 221 to prevent backflow of liquid when the pipelines are connected.

[0187] When the heating outlet 2620 is connected to the first liquid spraying inlet 1261, a connecting pipe plug structure can be provided on the pile body 20 and the cleaning base 120, so that the cleaning liquid can be sprayed from the pile body 20 to the cleaning base 120 from the first nozzle 1262. The pipe plug structure can be the same as the plug structure of the liquid outlet 127 to be heated and the liquid inlet 240 to be heated, and will not be repeated here.

[0188] In some embodiments, the cleaning apparatus 10 further includes a sewage tank 150 and a sewage suction channel 123. The sewage tank 150 is configured to receive sewage. The sewage suction channel 123 includes an inlet and an outlet, the outlet communicating with the sewage tank 150. The inlet faces the cleaning roller 121 and is located on the side of the scraper 122 proximal to the pile body 20. The sewage suction channel 123 is configured to transport sewage extracted from the cleaning roller 121. The sewage tank 150 may be a negative pressure water tank. Through negative pressure, the scraper 122 draws sewage from the cleaning roller 121 and the ground to be cleaned through the sewage suction channel 123 into the sewage tank 150.

[0189] When the cleaning device 10 performs self-cleaning on the pile body 20 , the sewage generated by cleaning can be sucked into the sewage tank 150 through the sewage suction channel 123 .

[0190] In some embodiments, as shown in Figures 4 and 5 , the cleaning device 10 further includes a scraper 122. The scraper 122 is disposed within the base housing 1201 and extends axially along the cleaning roller 121. The scraper 122 is configured to scrape liquid, i.e., wastewater, from the cleaning roller 121. The scraper 122 may 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 122 draws wastewater from the cleaning roller 121 and the ground to be cleaned through the wastewater suction channel 123 into the wastewater tank 150.

[0191] Among them, when the pile body 20 supports the cleaning equipment 10, on the circumference of the cleaning roller 121, the angle between the second nozzle 221 and the scraper 122 is greater than or equal to the preset angle, so that there is a distance between the second nozzle 221 and the scraper 122; the preset angle can be 90°, that is, the angle between the second nozzle 221 and the scraper 122 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 second nozzle 221 and the scraper 122 greater than or equal to 90° in the circumferential direction of the cleaning roller 121, there is sufficient distance between the second nozzle 221 and the scraper 122, 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 also a certain distance between the second nozzle 221 and the channel inlet of the sewage suction channel 123, so as to prevent the cleaning liquid sprayed by the second nozzle 221 from being directly sucked into the sewage suction channel 123.

[0192] In some embodiments, as shown in Figure 15, the pile body 20 also includes: a drying module 230, which is configured to provide airflow; an air outlet 231 of the drying module 230 is provided on the shell 200 of the pile body 20, and the drying module 230 outputs airflow from the air outlet 231 through the drying air duct 232 to dry the cleaning roller 121; the airflow output by the drying module 230 through the air outlet 231 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.

[0193] Among them, the air outlet 231 is located outside the roller groove 210; after the cleaning roller 121 completes cleaning on the pile body 20, it needs to be dried. By locating the air outlet 231 outside the roller groove 210, 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 by the second nozzle 221 from entering the air outlet 231.

[0194] Of course, the air outlet 231 of the drying module 230 can also be located within the roller groove 210. When the second nozzle 221 is located within the roller groove 210, the air outlet 231 is located on the side of the roller groove 210 closer to the opening of the roller groove 210 relative to the second nozzle 221. This prevents the cleaning liquid sprayed from the second nozzle 221 from entering the air outlet 231. Furthermore, the air outlet 231 of the drying module 230 can be provided both outside and inside the roller groove 210, that is, the drying module 230 has multiple air outlets 231.

[0195] In some embodiments, as shown in FIG9 , the floor scrubber is provided with a charging port 128 ; as shown in FIG11 , the pile body 20 is provided with a charging connector 250 . When the floor scrubber is placed back on the pile body 20 after use, the charging port 128 on the floor scrubber connects with the charging connector 250 on the pile body 20 , thereby charging the floor scrubber through the pile body 20 . This allows the floor scrubber to be charged and the cleaning fluid to be electrically heated through the pile body 20 .

[0196] As shown in Figure 15 , a power adapter 270 is provided within the pile body 20. The power adapter 270 connects to the charging connector 250 and the heating module 260 to respectively power the charging connector 250 and the heating module 260. This single power adapter 270 controls the power supply for both the heating module 260 and the scrubber, eliminating the need for additional components and thus avoiding increasing the bulk of the pile body 20.

[0197] The embodiment of the present disclosure further provides a cleaning device, which can be a floor scrubber. Below, in this embodiment, the cleaning device will be described in detail using a handheld floor scrubber as an example.

[0198] As shown in Figures 1 and 2, the handheld floor scrubber includes a cleaning base 20 and a liquid supply assembly. The cleaning base 20 is provided with a cleaning head, a liquid outlet 127 to be heated, and a first nozzle 1262 for cleaning the cleaning head. The liquid supply assembly is configured to supply liquid to at least one of the first nozzle 1262 and the liquid outlet 127 to be heated.

[0199] Specifically, as shown in Figures 1 and 2, 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 holds the handle assembly 130 to control the cleaning base 120 to move on the surface to be cleaned, thereby achieving the purpose of cleaning the surface to be cleaned.

[0200] As shown in Figures 3, 9 and 11, the cleaning base 120 includes a base housing 1201. The cleaning roller 121 of the cleaning base 120 is disposed on the bottom wall of the base housing 1201 and is exposed from the bottom wall, and the bottom surface of the cleaning roller 121 is closer to the surface to be cleaned than the bottom wall of the base housing 1201, so that when the cleaning roller 121 contacts the surface to be cleaned, there is a gap between the bottom wall of the base housing 1201 and the surface to be cleaned, thereby preventing the base housing 1201 from being worn.

[0201] Specifically, the liquid supply component includes a first liquid outlet and a second liquid outlet, and the liquid supply component is configured to control the liquid discharge of at least one of the first liquid outlet and the second liquid outlet, that is, only the first liquid outlet discharges liquid, or only the second liquid outlet discharges liquid, or the first liquid outlet and the second liquid outlet discharge liquid at the same time.

[0202] In some embodiments, as shown in Figures 2 and 6, the liquid supply assembly includes a liquid supply tank 140, a liquid supply pump 124, and a liquid dispensing controller 125. The liquid supply tank 140 can be fixed to the device body 110. Placing the liquid supply tank 140 on the device body 110 can, on the one hand, relatively increase the height of the liquid supply tank 140, making water supply more convenient, and on the other hand, avoid increasing the size of the cleaning base 120 by placing it on the cleaning base 120, while also avoiding affecting the difficulty of rotating the cleaning base 120.

[0203] As shown in Figures 6 and 7, the liquid supply pump 124 is disposed within the accommodation space of the base housing 1201 of the cleaning base 120, for example, fixed to the bottom wall of the base housing 1201. The inlet 1241 of the liquid supply pump 124 can be connected to the liquid supply tank 140 via a hose, so as to prevent the pipe connecting the liquid supply pump 124 and the liquid supply tank 140 from affecting the rotation of the cleaning base 120 relative to the device body 110 and to prevent the pipe from breaking.

[0204] Among them, the liquid supply pump 124 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 124. 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 124 can also be a vane pump, a centrifugal pump, an axial flow pump, etc., and the present disclosure does not limit this.

[0205] As shown in Figures 6 and 7, the liquid separation controller 125 is disposed in the accommodation space of the base housing 1201 of the cleaning base 120, for example, fixed to the bottom wall of the base housing 1201, and spaced apart from the liquid supply pump 124. The liquid separation controller 125 includes a controller liquid inlet 1251, a first liquid outlet 1252, and a second liquid outlet 1253. The controller liquid inlet 1251 is connected to the outlet 1242 of the liquid supply pump 124. The liquid separation controller 125 is configured to control the first liquid outlet 1252 to discharge liquid, the second liquid outlet 1253 to discharge liquid, or the first liquid outlet 1252 to discharge liquid and the second liquid outlet 1253 to discharge liquid simultaneously when the liquid separation controller 125 is in the open state. When the liquid separation controller 125 is in the closed state, neither the first liquid outlet 1252 nor the second liquid outlet 1253 discharges liquid.

[0206] The liquid dispensing controller 125 may include an electrically controlled liquid dispenser, such as a solenoid valve. By configuring the solenoid valve, the controller may be used to control the flow direction of the cleaning liquid, and may also be used to control the flow rate, flow velocity, etc. The liquid dispensing controller 125 may also include a mechanical liquid dispenser, such as a mechanical valve. After the user places the cleaning device 10 on the pile body 20, the user may set a mechanical switch on the cleaning device 10 to control the flow direction of the mechanical liquid dispenser, thereby controlling the discharge of liquid from the first liquid outlet 1252 and / or controlling the discharge of liquid from the second liquid outlet 1253.

[0207] 8 , the cleaning base 120 is provided with a first nozzle 1262 , which is connected to the first liquid outlet 1252 of the liquid separation controller 125 via a pipeline. The cleaning liquid can be sprayed onto the cleaning roller 121 through the first nozzle 1262 to clean the cleaning roller 121 .

[0208] As shown in Figures 9 and 10, the cleaning base 120 is provided with a heated liquid outlet 127, which can be provided on the bottom wall of the base shell 1201 of the cleaning base 120. When the cleaning device 10 is positioned on the pile body 20, the heated liquid outlet 127 faces the pile body 20. The heated liquid outlet 127 can be formed by a liquid outlet connector provided on the bottom wall of the base shell 1201 to facilitate subsequent connection with other pipelines or interfaces.

[0209] The liquid outlet 127 to be heated is connected to the second liquid outlet 1253 of the liquid separation controller 125 via a pipeline. When the liquid separation controller 125 controls the second liquid outlet 1253 to discharge liquid, the cleaning liquid in the liquid supply tank 140 is driven by the liquid supply pump 124 and then flows through the second liquid outlet 1253 of the liquid separation controller 125 to the liquid outlet 127 to be heated, so that the cleaning liquid flows to the pile body 20.

[0210] In some embodiments, as shown in Figure 17, the liquid supply component includes: a liquid supply tank 140, a liquid supply pump 124 and a control valve 160; the inlet of the liquid supply pump 124 is connected to the liquid supply tank 140, and the control valve 160 includes a control valve liquid inlet and a control valve liquid outlet, and the control valve liquid inlet is connected to the outlet of the liquid supply pump 124.

[0211] As shown in FIG8 , a first nozzle 1262 is provided on the cleaning base 120 , and cleaning liquid can be sprayed onto the cleaning roller 121 through the first nozzle 1262 to clean the cleaning roller 121 .

[0212] As shown in Figures 9 and 10, the cleaning base 120 is provided with a heated liquid outlet 127, which can be provided on the bottom wall of the base shell 1201 of the cleaning base 120. When the cleaning device 10 is positioned on the pile body 20, the heated liquid outlet 127 faces the pile body 20.

The outlet of the liquid supply tank 140 is connected to the heated liquid outlet 127.

[0237] A pressure valve 172 is provided between the liquid supply tank 140 and the liquid outlet 127 to be heated; when the floor scrubber is not placed on the pile, the pressure valve 172 is in a closed state.

[0238] Among them, the first liquid supply pump 181 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, and will not cause corrosion to the pump body, thereby improving the reliability and life of the first liquid supply pump 181. 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 first liquid supply pump 181 can also be a vane pump, a centrifugal pump, an axial flow pump, etc., and the present disclosure does not limit this.
