[0103] The exemplary embodiments will now be described in more detail with reference to the accompanying figures. However, the exemplary embodiments may be implemented in various forms and should not be construed as limited to the embodiments described herein; rather, these embodiments are provided so that this disclosure is complete and comprehensive, and fully conveys the concept of the embodiments to those skilled in the art. Like reference numerals in the figures indicate identical or similar structures, and their detailed description will therefore be omitted.

[0104] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of a figure to another, these terms are used in this specification only for convenience, such as in relation to the orientation of the examples depicted in the accompanying figures. It is understood that if the device of the figure is turned over, the component described as "upper" will become a "lower" component. When a structure is "on" another structure, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" placed on the other structure, or that the structure is "indirectly" placed on the other structure via another structure.

[0105] The terms "a", "an", "the", "the", "said", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "includes" and "has" are used to indicate open inclusion and mean that in addition to the listed elements / components / etc., other elements / components / etc. may exist; the terms "first", "second", etc. are used for identification purposes only and do not constitute a limitation on the number of their objects.

[0106] In the related technology, cleaning devices such as floor cleaning devices typically have a clean water tank that supplies cleaning fluid to the cleaning head when cleaning the floor. After use, the cleaning device is typically returned to a charging station that supports it and can perform self-cleaning of the cleaning device, such as automatically washing the cleaning head. The cleaning head may be, for example, a cleaning roller providing a strip-shaped cleaning surface, or a cleaning brush or cleaning disc providing a circular cleaning surface.

[0107] However, when automatically cleaning the cleaning head by the charging station, the temperature of the cleaning liquid is relatively low, resulting in a relatively poor cleaning effect.

[0108] As illustrated in Figures 1 and 2, the cleaning system comprises a cleaning device 10 and a charging station 20, the cleaning device 10 being able to be a portable floor cleaning device. It should be noted that the description of the cleaning device in this disclosure through a cleaning device 10 is only a preferred embodiment of this disclosure and does not limit the scope of protection of the cleaning device of this disclosure. For example, the cleaning device of this disclosure may be a portable cleaning device 10 with a handle and manually manipulated by the user, or an autonomously moving floor cleaning robot with driving wheels, capable of controlling the advancement of the driving wheels and the cleaning of the floor by the cleaning roller according to a program stored on a medium embedded in the device or integral with the charging station.Another example is that the cleaning device of this disclosure may also be a floor washing machine, a broom, an electric mop or other cleaning devices.

[0109] To solve the above-mentioned technical problem, the charging station 20 provided by this disclosure is equipped with a heating module, the heating module being configured to provide heat to heat the cleaning liquid. The cleaning liquid may enter the charging station 20 to be heated, or the heating module on the charging station 20 may directly heat the cleaning liquid in the cleaning device 10, thereby improving the cleaning effect of the cleaning liquid on the cleaning head and the use performance of the charging station 20.

[0110] In the following, embodiments of this disclosure will be explained in detail by taking as an example a cleaning system comprising a portable cleaning device 10 and a charging station, with a cleaning roller as a cleaning head.

[0111] As illustrated in Figures 1 and 2, the portable floor cleaning device 10 comprises a cleaning base 120 and a liquid supply assembly. The cleaning base 120 is equipped with a cleaning head, a liquid outlet to be heated 127 and a first liquid spray nozzle 1262 for cleaning the cleaning head. The liquid supply assembly is configured to supply liquid to at least one of the ports of the first liquid spray nozzle 1262 and the liquid outlet to be heated 127. The charging station 20 is equipped with a liquid inlet to be heated 240 for connecting to the liquid outlet to be heated 127, the charging station 20 being configured to be able to heat the cleaning liquid entering the liquid inlet to be heated 240. The charging station 20 is equipped with a second liquid spray nozzle 221 for cleaning the cleaning head.The heated cleaning liquid may be sprayed from the second liquid spray nozzle 221, or from the first liquid spray nozzle 1262, or simultaneously from the first liquid spray nozzle 1262 and the second liquid spray nozzle 221.

[0112] More specifically, as illustrated in Figures 1 and 2, the portable floor cleaning device 10 also comprises a device body 110, the cleaning base 120 being connected to one end of the device body 110; a handle assembly 130 is provided on the device body 110, the handle assembly 130 being connected to the end of the device body 110 away from the cleaning base 120, to allow the user to manipulate and hold it, the user controlling the movement of the cleaning base 120 on the surface to be cleaned by holding the handle assembly 130, thereby achieving the purpose of cleaning the surface to be cleaned.

[0113] The cleaning base 120 is hinged to the device body 110, for example by a pivot joint, a ball joint connection, etc.; when the user holds the handle assembly 130 to control the movement of the cleaning base 120 on the surface to be cleaned, the hinge between the cleaning base 120 and the device body 110 allows the relative angle between the device body 110 and the cleaning base 120 to be adjusted, thereby changing the operating angle and flexibly adjusting the cleaning posture to facilitate the cleaning operation.

[0114] As illustrated in Figures 3, 9 and 11, the cleaning base 120 comprises a base housing 1201, the base housing 1201 comprising a top wall, side walls and a bottom wall, the top wall, the side walls and the bottom wall together forming a containment space. The cleaning roller 121 is provided on the bottom wall of the base casing 1201, protruding 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 casing 1201, so that when the cleaning roller 121 is in contact with the surface to be cleaned, there is a gap between the bottom wall of the base casing 1201 and the surface to be cleaned, to prevent wear of the base casing 1201. The number of cleaning rollers 121 may be, for example, one, two or more, and the cleaning rollers 121 may rotate at high speed to wash the floor.The cleaning roller 121 may be composed of a rotating shaft and a cleaning cloth wrapping the surface of the shaft, the shaft rotating at a high speed under the driving effect to rotate the cleaning surface at a high speed, thereby realizing high-speed rotary friction cleaning of the surface to be cleaned; the cleaning cloth may be detachable from the shaft, facilitating the replacement of the cleaning cloth and improving the maintenance economy of the cleaning roller 121.

[0115] As illustrated in [Fig.9], the lower portion of the cleaning base 120 is equipped with a first roller 1291, the first roller 1291 being arranged on the side of the lower portion of the cleaning base 120 away from the cleaning roller 121, the rotation axis of the first roller 1291 being able to be parallel to the rotation axis of the cleaning roller 121. The installation of the first roller 1291 helps the movement when the user manipulates the cleaning base 120 on the surface to be cleaned, thus avoiding friction between the casing of the base 1201 and the surface to be cleaned. At the same time, a second roller 1292 may be installed on the lower part of the cleaning base 120 near the cleaning roller 121, the second roller 1292 having a smaller diameter than the first roller 1291, serving to facilitate the movement of the cleaning base 120 and the rotation of the cleaning roller 121.By means of the second roller 1292, a support can be formed for the base casing 1201 near the cleaning roller 121, thereby reducing resistance when moving the cleaning base 120 by the user.

[0116] More specifically, the liquid supply assembly comprises a first liquid outlet and a second liquid outlet, the liquid supply assembly being configured to control the liquid output of at least one of the first liquid outlet and the second liquid outlet, i.e., only the first liquid outlet supplies liquid, or only the second liquid outlet supplies liquid, or both the first liquid outlet and the second liquid outlet supply liquid simultaneously.

[0117] In some embodiments, as illustrated in Figures 2 and 6, the liquid supply assembly includes a liquid reservoir 140, a liquid pump 124, and a liquid dispensing controller 125, wherein the liquid reservoir 140 may be fixed on the device body 110. Installing the liquid tank 140 on the device body 110 allows on the one hand to relatively increase the height of the liquid tank 140, thus facilitating water supply, and on the other hand to avoid increasing the volume of the cleaning base 120 by installing it thereon, while avoiding affecting the difficulty of rotating the cleaning base 120 during operation / use.

[0118] As illustrated in Figures 6 and 7, the liquid pump 124 is installed in the containment space of the base housing 1201 of the cleaning base 120, for example fixed on the bottom wall of the base housing 1201. The inlet 1241 of the liquid pump 124 may be connected to the liquid reservoir 140 by a flexible pipe, in order to avoid the impact of the pipes connecting the liquid pump 124 and the liquid reservoir 140 on the rotation of the cleaning base 120 relative to the body of the device 110, while avoiding pipe breakages.

[0119] The liquid pump 124 is for example a peristaltic pump. Since the cleaning liquid is generally an aqueous solution containing cleaning solvents, which has a certain corrosive effect, the use of a peristaltic pump for liquid supply means that the cleaning liquid only contacts the pump tube, without touching the pump body, thus avoiding corrosion of the pump body, improving the reliability and service life of the liquid pump 124. In addition, the peristaltic pump provides accurate flow rate, high stability, good sealing, simple maintenance, without valves or seals. Of course, the liquid pump 124 may also be a vane pump, a centrifugal pump, an axial pump, etc., the present disclosure not limiting this.

[0120] The cleaning liquid in the liquid tank 140 may also be water or a solution of water and detergent, without being limited by the present disclosure, as long as it can achieve the cleaning effect on the cleaning roller 121.

[0121] As illustrated in Figures 6 and 7, the liquid dispensing controller 125 is installed in the containment space of the base housing 1201 of the cleaning base 120, for example fixed on the bottom wall of the base housing 1201, spaced from the liquid pump 124. The liquid dispensing controller 125 includes a liquid inlet of the controller 1251, a first liquid outlet 1252 and a second liquid outlet 1253, the liquid inlet of the controller 1251 being in communication with the outlet 1242 of the liquid pump 124; the liquid dispensing controller 125 is configured to be able to control the liquid output from the first liquid outlet 1252, or from the second liquid outlet 1253, or to control the simultaneous liquid output from the first liquid outlet 1252 and the second liquid outlet 1253 when it is in the open state; when the liquid dispensing controller 125 is in the closed state, neither the first liquid outlet 1252 nor the second liquid outlet 1253 exits liquid.

[0122] The liquid dispensing controller 125 may comprise an electrically controlled liquid dispenser, for example a solenoid valve, which may be used in combination with a controller to realize the control of the flow direction of the cleaning liquid, as well as the control of the flow rate, the flow speed, etc. Of course, the liquid dispensing controller 125 may also comprise a mechanical liquid dispenser, for example a mechanical valve, and after placing the cleaning device 10 on the charging station 20, the user can control the flow direction of the mechanical dispenser via a mechanical switch installed on the cleaning device 10, thereby realizing the control of the liquid output of the first liquid outlet 1252 and / or the second liquid outlet 1253.

[0123] As illustrated in [Fig.8], a first liquid spray nozzle 1262 is installed on the cleaning base 120, the first liquid spray nozzle 1262 being connected to the first liquid outlet 1252 of the liquid dispensing controller 125 by a pipeline. The first liquid spray nozzle 1262 is used to spray the cleaning liquid onto the cleaning roller 121 to clean it.

[0124] As illustrated in Figures 9 and 10, a heating liquid outlet 127 is installed on the cleaning base 120, the heating liquid outlet 127 may be installed on the bottom wall of the base casing 1201 of the cleaning base 120; when the cleaning device 10 is on the charging station 20, the heating liquid outlet 127 is oriented toward the charging station 20. The heating liquid outlet 127 may be formed by a liquid outlet fitting installed on the bottom wall of the base casing 1201, to facilitate subsequent connection with other pipes or interfaces.

[0125] The liquid outlet to be heated 127 is connected to the second liquid outlet 1253 of the liquid dispensing controller 125 by a conduit. When the liquid dispensing controller 125 controls the liquid outlet of the second liquid outlet 1253, the cleaning liquid of the liquid tank 140 is driven by the liquid pump 124, then passes through the second liquid outlet 1253 of the liquid dispensing controller 125 to flow to the liquid outlet to be heated 127, thereby allowing the cleaning liquid to flow to the refill station 20.

[0126] More specifically, as illustrated in Figures 11 to 16, the recharging station 20 comprises a casing 200 and a heating module 260, the casing 200 forming an inlet for liquid to be heated 240 and a receiving groove for housing the cleaning roller 121, namely the roller groove 210; when the recharging station 20 supports the cleaning device 10, the liquid inlet to be heated 240 is in communication with the liquid outlet to be heated 127. The heating module 260 may be an electric heating module.

[0127] As illustrated in Figures 15 and 16, the heating module 260 comprises a heating inlet 2610 and a heating outlet 2620, the heating inlet 2610 being connected to the inlet for liquid to be heated 240 by a pipeline, so that when the liquid distribution controller 125 controls the liquid outlet of the second liquid outlet 1253, the cleaning liquid of the liquid tank 140 is driven by the liquid pump 124, then passes through the liquid distribution controller 125 to the outlet for liquid to be heated 127, enters the inlet for liquid to be heated 240, and then enters the receiving cavity of the heating module 260; then, the heating module 260 is configured to heat the liquid entered into the receiving cavity of the heating module 260 to a predefined temperature, the predefined temperature being for example in the range of 40°C to 60°C, for example 40°C, 45°C, 50°C, 55°C, 60°C, etc., the present disclosure not listing all of them herein; by heating the cleaning liquid to a temperature in the range of 40°C to 60°C, the activity of the cleaning liquid can be increased, thereby improving the cleaning effect of the cleaning liquid, while preventing excessively high temperatures from affecting the activity of the cleaning liquid; of course, the preset temperature can also be lower than 40°C or higher than 60°C, the present disclosure not limiting it.

[0128] As illustrated in [Fig.13], the housing 200 is equipped with a liquid spray nozzle for spraying liquid onto the cleaning roller 121, namely the second liquid spray nozzle 221, the second liquid spray nozzle 221 being connected to the heating outlet 2620 of the heating module 260 by a pipeline, so as to spray the cleaning liquid heated to the preset temperature by the heating module 260 onto the cleaning roller 121; the higher temperature cleaning liquid can improve the cleaning effect on the cleaning roller 121.

[0129] The second liquid spray nozzle 221 may be oriented toward the cleaning roller 121, that is, the second liquid spray nozzle 221 may directly spray the cleaning liquid onto the cleaning roller 121; or, the second liquid spray nozzle 221 may spray the cleaning liquid near the cleaning roller 121, causing the cleaning liquid to splash onto the cleaning roller 121 or flow onto the cleaning roller 121 through other structures, the present disclosure not limiting it, as long as the cleaning of the cleaning roller 121 can be achieved by the cleaning liquid.

[0130] When the first liquid outlet 1252 and the second liquid outlet 1253 exit the liquid simultaneously, the first liquid spray nozzle 1262 and the second liquid spray nozzle 221 can simultaneously spray the cleaning liquid onto the cleaning roller 121, so as to improve the cleaning effect on the cleaning roller 121.

[0131] Thus, by combining the liquid tank 140 and the liquid dispensing controller 125 on the cleaning device 10, as well as the heating module 260 and the second liquid spray nozzle 221 on the refill station 20, the purpose of spraying cleaning liquid at a predefined temperature onto the cleaning roller 121 is achieved; the use of the liquid tank 140 and the liquid dispensing controller 125 makes it possible to realize a two-way liquid supply from a single liquid tank 140, thus avoiding the installation of a separate liquid tank in the refill station 20, which avoids increasing the volume of the refill station 20 for self-cleaning of the cleaning roller 121, thus reducing the cost of the refill station 20;at the same time, the user only needs to maintain one liquid tank on the cleaning device 10, which is more convenient for the user and improves the market competitiveness of the product. ;

[0132] In some embodiments, the charging station 20 includes a liquid pump, the liquid pump being used to draw cleaning liquid from the cleaning device 10 located on the charging station 20.

[0133] The inlet of the liquid pump is in communication with the liquid inlet on the charging station 20, that is to say it can be in communication with the inlet of liquid to be heated 240, the outlet of the liquid pump is in communication with the heating inlet of the heating module 260; or, the inlet of the liquid pump is in communication with the heating outlet of the heating module 260, the heated cleaning liquid being discharged through the outlet of the liquid pump.

[0134] When the refilling station contains a liquid pump, the liquid supply assembly comprises: a liquid reservoir 140 and a first liquid pump, the inlet of the first liquid pump being in communication with the liquid reservoir 140; that is, the liquid pump in the refilling station 20 can be considered as a second liquid pump.

[0135] As illustrated in [Fig.8], a first liquid spray nozzle 1262 is installed on the cleaning base 120, the first liquid spray nozzle 1262 being connected to the outlet of the first liquid pump by a pipeline. The first liquid spray nozzle 1262 is used to spray the cleaning liquid onto the cleaning roller 121 to clean it.

[0136] As illustrated in Figures 9 and 10, a heating liquid outlet 127 is installed on the cleaning base 120, the heating liquid outlet 127 may be installed on the bottom wall of the base casing 1201 of the cleaning base 120; when the cleaning device 10 is on the charging station 20, the heating liquid outlet 127 is oriented toward the charging station 20. The heating liquid outlet 127 may be formed by a liquid outlet fitting installed on the bottom wall of the base casing 1201, to facilitate subsequent connection with other pipes or interfaces. The outlet of the liquid tank 140 is in communication with the heating liquid outlet 127.

[0137] A heating liquid inlet 240 is formed on the casing 200 of the charging station 20, when the charging station 20 supports the cleaning device 10, the heating liquid inlet 240 is in communication with the heating liquid outlet 127. The inlet of the second liquid pump in the charging station 20 is in communication with the heating liquid inlet 240, thus enabling the second liquid pump to suck the cleaning liquid from the liquid tank 140 in the charging station 20.

[0138] A pressure valve is installed between the liquid tank 140 and the liquid outlet to be heated 127; when the cleaning device 10 is not placed on the recharging station 20, the pressure valve is in the closed position; when the cleaning device 10 is placed on the recharging station 20, and the suction pressure supplied by the second liquid pump is lower than a preset pressure value, the pressure valve is in the closed position, and when the suction pressure supplied by the second liquid pump is greater than or equal to the preset pressure value, the pressure valve is in the open position; the preset pressure value can be adjusted as needed, without being limited by the present disclosure.

[0139] As illustrated in Figures 11 to 16, the charging station 20 comprises a casing 200 and a heating module 260, the heating module 260 comprising a heating inlet 2610 and a heating outlet 2620, the heating inlet 2610 being connected to the inlet for liquid to be heated 240 by a pipe, the second liquid pump being located between the heating inlet 2610 and the inlet for liquid to be heated 240, when the second liquid pump sucks the cleaning liquid from the liquid tank 140 to the heating module, the cleaning liquid enters the receiving cavity of the heating module 260; then, the heating module 260 is configured to heat the liquid entered into the receiving cavity of the heating module 260 to a predefined temperature, the predefined temperature being for example of the order of 40°C to 60°C.

[0140] The second liquid pump may also be located between the heater outlet 2620 and the second liquid spray nozzle 221, in order to open the pressure valve to draw cleaning liquid from the liquid reservoir 140.

[0141] When the first liquid pump exits the liquid, the first liquid spray nozzle 1262 sprays the cleaning liquid onto the cleaning roller 121; when the second liquid pump exits the liquid, the second liquid spray nozzle 221 sprays the cleaning liquid onto the cleaning roller 121; when the first liquid pump and the second liquid pump exit the liquid simultaneously, the first liquid spray nozzle 1262 and the second liquid spray nozzle 221 can simultaneously spray the cleaning liquid onto the cleaning roller 121, so as to improve the cleaning effect on the cleaning roller 121.

[0142] The first liquid pump and the second liquid pump are for example peristaltic pumps, since the cleaning liquid is generally an aqueous solution containing cleaning solvents, which has a certain corrosive effect, the use of peristaltic pumps for liquid supply means that the cleaning liquid only contacts the pump tube, without touching the pump body, thus avoiding corrosion of the pump body, improving the reliability and service life of the first liquid pump and the second liquid pump, while providing accurate flow rate, high stability, good sealing, simple maintenance, without valves and seals; of course, the first liquid pump and the second liquid pump may also be vane pumps, centrifugal pumps, axial pumps, etc., the present disclosure not limiting them.

[0143] In some embodiments, as illustrated in [Fig. 15], the housing 200 of the charging station 20 forms a receiving space, the heating module 260 being housed in the receiving space. The heating module 260 has a relatively small volume and occupies little space.The heating module 260 comprises a heating module housing, the heating inlet 2610 and the heating outlet 2620 being arranged on the heating module housing, the heating module housing 260 forming an accommodating cavity, an electric heating wire or an electric heating column being arranged in the accommodating cavity to heat the liquid flowing in the accommodating cavity; a flow channel may also be arranged in the accommodating cavity, the heating inlet 2610 and the heating outlet 2620 being arranged at the inlet and outlet of the flow channel, so as to guide the flow of the cleaning liquid in the accommodating cavity and improve the heating efficiency of the cleaning liquid.

[0144] In some embodiments, the cleaning liquid does not enter the heating module 260, the heating module 260 being disposed proximate the pipe carrying the cleaning liquid, thereby heating the pipe carrying the cleaning liquid by generating heat, thereby achieving the objective of heating the cleaning liquid in the pipe.

[0145] In some embodiments, the cleaning liquid may also not enter the charging station 20, the heating module 260 being disposed on the charging station 20 near the support surface supporting the cleaning base 120; the pipeline used to transport the cleaning liquid to the first liquid spray nozzle 1262 is disposed on the bottom of the cleaning base 120, i.e., when the cleaning base 120 is on the charging station 20, the heating module 260 is adjacent to the pipeline transporting the cleaning liquid, whereby the heat generated by the heating module 260 can heat the cleaning liquid in the pipeline, thereby enabling the first liquid spray nozzle 1262 to spray cleaning liquid at a preset temperature, thereby improving the cleaning effect.

[0146] In this case, the charging station 20 may not be equipped with a liquid inlet to be heated 240 and a second liquid spray nozzle 221, thus reducing the production cost of the charging station 20.

[0147] Of course, the cleaning liquid heated in the cleaning base 120 can also enter the charging station 20 via the liquid inlet to be heated 240 on the charging station 20, and then be sprayed via the second liquid spray nozzle 221 on the charging station 20.

[0148] The heating module 260 may protrude from the casing 200 of the charging station 20, in order to improve the heating effect of the cleaning liquid in the cleaning base 120. The pipe carrying the cleaning liquid in the cleaning base 120 may also protrude from the casing of the base 1201 of the cleaning base 120, in order to improve the heating effect of the cleaning liquid. Of course, the heating module 260 and the pipe carrying the cleaning liquid may also not protrude, the present disclosure not limiting them.

[0149] When the charging station 20 is equipped with a liquid pump, the liquid pump can suck the heated cleaning liquid into the charging station 20 via the liquid inlet 240, and then spray it via the second liquid spray nozzle 221; the liquid inlet can be the liquid inlet to be heated 240, or can be directly connected to the cleaning base 120 via the inlet of the liquid pump, in order to suck the heated cleaning liquid into the charging station 20.

[0150] The inlet of the liquid pump is in communication with the liquid inlet, the outlet of the liquid pump is in communication with the heating inlet of the module of heater 260; or, the inlet of the liquid pump is in communication with the heater outlet of the heater module 260, the heated cleaning liquid being discharged through the outlet of the liquid pump.

[0151] In some embodiments, as illustrated in Figures 6-8, a first liquid spray assembly is installed on the cleaning base 120, the first liquid spray assembly comprising a first liquid spray inlet 1261 and a plurality of first liquid spray nozzles 1262, the first liquid spray inlet 1261 being in communication with the plurality of first liquid spray nozzles 1262, the cleaning liquid being supplied to the first liquid spray assembly via the first liquid spray inlet 1261 and then sprayed by the plurality of first liquid spray nozzles 1262.The first plurality of liquid spray nozzles 1262 are successively arranged along the axis of the cleaning roller 121, allowing the cleaning liquid to be sprayed at different positions along the axis of the cleaning roller 121, so as to improve the wetting effect of the cleaning roller 121.

[0152] In some embodiments, as illustrated in Figures 13 and 14, a second liquid spray assembly 220 is installed on the recharging station 20, the second liquid spray assembly 220 comprising a second liquid spray inlet 222 and a plurality of second liquid spray nozzles 221, the plurality of second liquid spray nozzles 221 being successively arranged along the axis of the cleaning roller 121, allowing the cleaning liquid to be sprayed at different positions along the axis of the cleaning roller 121, in order to improve the wetting effect of the cleaning roller 121.The inlet of the second liquid spray assembly 220 is in communication with the heating outlet 2620 of the heating module 260 by a pipeline, the cleaning liquid at the preset temperature exiting from the heating outlet 2620 of the heating module 260 flows to the second liquid spray assembly 220, and then is sprayed onto the cleaning roller 121 at the preset temperature by the several second liquid spray nozzles 221 of the second liquid spray assembly 220.

[0153] The second liquid spray nozzles 221 on the second liquid spray assembly 220 are formed by installing several nozzles, by adjusting the shape and size of the nozzle orifice, the coverage area and flow rate of the cleaning liquid sprayed by the second liquid spray nozzles 221 can be changed, so as to improve the spraying effect of the cleaning liquid on the cleaning roller 121; the design can be made according to actual needs, without being limited by the present disclosure.

[0154] As illustrated in [Fig. 13], the multiple second liquid spray nozzles 221 are located in the roller groove 210. When the recharging station 20 supports the cleaning device 10, the cleaning roller 121 of the cleaning device 10 is housed in the roller groove 210. The placement of the multiple second liquid spray nozzles 221 in the roller groove 210 allows the cleaning liquid sprayed by the second liquid spray nozzles 221 to be on the cleaning roller 121, thereby avoiding waste of cleaning liquid. In addition, since the cleaning roller 121 and the multiple second liquid spray nozzles 221 are both located in the roller groove 210, the gap between the second liquid spray nozzles 221 and the cleaning roller 121 is relatively small, which improves the wetting effect of the cleaning roller 121.Furthermore, the blocking by the walls of the roller groove 210 prevents the cleaning liquid sprayed at high speed on the cleaning roller 121 from splashing the surroundings of the charging station 20, thereby preventing the self-cleaning of the cleaning roller 121 from affecting the environmental hygiene around the charging station 20.

[0155] Of course, the multiple second liquid spray nozzles 221 may be located outside the roller groove 210, i.e., the multiple nozzles are placed outside the roller groove 210, with their spraying direction facing the cleaning roller 121 located in the roller groove 210, in order to improve the wetting effect of the cleaning roller 121 by the cleaning liquid sprayed from the second liquid spray nozzles 221. Alternatively, some second liquid spray nozzles 221 may be located in the roller groove 210 and others outside, forming a double-row spray nozzle arrangement, to further improve the wetting and cleaning effect of the cleaning roller 121.

[0156] In some embodiments, as illustrated in Figures 9 to 12, the heating liquid outlet 127 and the heating liquid inlet 240 fit together. When the cleaning device 10 is replaced on the charging station 20 after use, the heating liquid outlet 127 and the heating liquid inlet 240 fit together, establishing communication between the heating liquid outlet 127 and the heating liquid inlet 240. The user does not need to perform any additional operations, it is the same operation as when a normal cleaning device 10 is replaced on the charging station 20 after use, simple and convenient.

[0157] In this case, the heating liquid outlet 127 may be located inside the heating liquid inlet 240. By placing the heating liquid outlet 127 inside the heating liquid inlet 240, when the heating liquid outlet 127 and the heating liquid inlet 240 fit together, this may improve the tightness of the connection. between the heating liquid outlet 127 and the heating liquid inlet 240, thus avoiding leaks at the connection point. Of course, the heating liquid inlet 240 may also be located inside the heating liquid outlet 127, the present disclosure not limiting it.

[0158] In addition, a seal is provided between the heating liquid outlet 127 and the heating liquid inlet 240, in order to form a sealed connection after the heating liquid outlet 127 and the heating liquid inlet 240 are fitted together. The seal may be installed on the outer surface of the outlet fitting forming the heating liquid outlet 127; or the seal may be installed on the inner wall of the orifice forming the heating liquid inlet 240; or seals may be installed on both the outer surface of the outlet fitting forming the heating liquid outlet 127 and the inner wall of the orifice forming the heating liquid inlet 240.The sealing gasket may be, for example, a rubber ring or the like, the rubber ring being removable to be installed, making it easy to replace when the sealing effect is not satisfactory, thereby improving the sealing effect.

[0159] In addition, the heating liquid outlet 127 and the heating liquid inlet 240 may also be connected by magnetic attraction, with magnetic pieces respectively installed on the heating liquid outlet 127 and the heating liquid inlet 240, using a strong magnet to tightly adhere the magnetic pieces of the heating liquid outlet 127 and the heating liquid inlet 240, thereby forming a sealed connection between the heating liquid outlet 127 and the heating liquid inlet 240, the magnetic attraction method facilitating connection and separation, with simple maintenance; the present disclosure does not limit this, any variation in the connection method between the heating liquid outlet 127 and the heating liquid inlet 240 falls within the protective scope of the present disclosure.

[0160] In some embodiments, complementary positioning structures may be provided on the casing of the base 1201 of the cleaning device 10 and on the casing 200 of the charging station 20, in order to help the cleaning device 10 to be replaced in a predefined position on the charging station 20 after use, thus improving the reliability of the interlocking between the outlet of liquid to be heated and the inlet of liquid to be heated 240. The positioning structure may be for example a positioning recess provided on the casing of the base 1201 and a positioning projection provided on the charging station 20, realizing the relative positioning of the cleaning device 10 when it is replaced on the charging station 20 thanks to the combination of the positioning projection and the positioning recess; multiple sets of positioning protrusions and positioning recesses can be arranged to further improve the auxiliary positioning effect.

[0161] The positioning structure may also include the rollers at the bottom of the cleaning device 10 and the roller grooves on the charging station 20, enabling relative positioning between the cleaning device 10 and the charging station 20 by means of the rollers and the roller grooves, improving the stability of the cleaning device 10 on the charging station 20 and thus ensuring the auxiliary positioning.

[0162] In some embodiments, the heating outlet 2620 of the heating module may be connected to the first liquid spray nozzle 1262, i.e., a hot water outlet may be provided on the charging station 20, wherein the heated cleaning liquid may be discharged through the hot water outlet, in order to spray the heated cleaning liquid from the first liquid spray nozzle 1262.

[0163] In this case, the heating outlet 2620 of the heating module can also be simultaneously connected to the first liquid spray nozzle 1262 and the second liquid spray nozzle 221, that is, when the cleaning device 10 is placed back on the charging station 20 for self-cleaning after use, the cleaning liquid heated to the preset temperature can be simultaneously sprayed onto the cleaning roller 121 by the first liquid spray nozzle 1262 and the second liquid spray nozzle 221, greatly improving the wetting and cleaning effect of the cleaning roller 121.

[0164] When the heating outlet 2620 of the heating module is simultaneously connected to the first liquid spray nozzle 1262 and the second liquid spray nozzle 221, two heating outlets may be provided on the heating module, one serving as a hot water outlet, the two heating outlets being respectively connected to the first liquid spray nozzle 1262 and the second liquid spray nozzle 221, or a single heating outlet 2620 may be provided on the heating module in combination with a distributor to realize the connection with the first liquid spray inlet 1261 and the second liquid spray nozzle 221.Check valves may be installed on the line connecting the heater outlet 2620 to the first liquid spray inlet 1261 and on the line connecting the heater outlet 2620 to the second liquid spray nozzle 221, in order to prevent backflow when the lines are connected.

[0165] When the heating outlet 2620 is connected to the first liquid spray inlet 1261, a pluggable pipe connection structure may be provided on the charging station 20 and the cleaning base 120, so that the cleaning liquid can be sprayed from the first liquid spray nozzle 1262 in the cleaning base 120 from the charging station 20. The plug-in pipe connection structure may be the same as the interlocking structure of the heating liquid outlet 127 and the heating liquid inlet 240, which will not be repeated here.

[0166] In some embodiments, the cleaning device 10 also comprises: a wastewater tank 150 and a dirt suction channel 123. The wastewater tank 150 is configured to contain the wastewater, the dirt suction channel 123 comprises a channel inlet and a channel outlet, the channel outlet being in communication with the wastewater tank 150, the channel inlet being oriented towards the cleaning roller 121 and located on the side of the squeegee (or cleaning blade) 122 close to the refill station 20, the dirt suction channel 123 being configured to transport the wastewater sucked from the cleaning roller 121. The wastewater tank 150 may be a negative pressure tank, sucking by negative pressure the wastewater from the squeegee 122 of the cleaning roller 121 and from the surface to be cleaned towards the wastewater tank 150 via the dirt suction channel 123.

[0167] When the cleaning device 10 performs self-cleaning on the charging station 20, the waste water produced by the cleaning can be sucked into the waste water tank 150 via the dirt suction channel 123.

[0168] In some embodiments, as illustrated in Figures 4 and 5, the cleaning device 10 also comprises: a squeegee 122. The squeegee 122 is disposed in the housing of the base 1201, the squeegee 122 extending along the axial direction of the cleaning roller 121, the squeegee 122 being configured to squeegee liquid onto the cleaning roller 121, i.e., wastewater onto the cleaning roller 121. The extension direction of the squeegee 122 may be parallel to the axis of the cleaning roller 121, in order to improve the squeegee effect of wastewater at different positions along the axis of the cleaning roller 121; the waste water scraped by the scraper 122 from the cleaning roller 121 and from the surface to be cleaned is sucked into the waste water tank 150 via the dirt suction channel 123.

[0169] When the charging station 20 supports the cleaning device 10, in the circumferential direction of the cleaning roller 121, the angle between the second liquid spray nozzle 221 and the squeegee 122 is greater than or equal to a predetermined angle, so that there is a gap between the second liquid spray nozzle 221 and the squeegee 122; the predetermined angle may be 90°, i.e., the angle between the second liquid spray nozzle 221 and the squeegee 122 may be, for example, 90°, 100°, 110°, 120°, 130°, 150°, 160°, 170°, 180°, etc., not all of which are listed here. By making the angle between the second liquid spray nozzle 221 and the squeegee 122 greater than or equal to 90° in the circumferential direction of the cleaning roller 121, there is sufficient space between the second liquid spray nozzle 221 and the squeegee 122, which allows the cleaning liquid to sufficiently 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 space with the inlet of the dirt suction channel 123, avoiding the cleaning liquid sprayed by the second liquid spray nozzle 221 from being directly sucked into the dirt suction channel 123.

[0170] In some embodiments, as illustrated in [Fig. 15], the charging station 20 also comprises: a drying module 230, the drying module 230 being configured to provide an airflow; the housing 200 of the charging station 20 is equipped with an air outlet 231 of the drying module 230, the drying module 230 discharging the airflow through the air outlet 231 via a drying air duct 232 to dry the cleaning roller 121; the airflow discharged by the drying module 230 via the air outlet 231 may be an airflow at ambient temperature or a heated airflow, the use of a heated airflow being more favorable for drying the cleaning roller 121.

[0171] The air outlet 231 is located outside the roller groove 210; after the cleaning roller 121 finishes cleaning on the charging station 20, it needs to be dried, by placing the air outlet 231 outside the roller groove 210, this can improve the circulation of the airflow, thereby improving the drying effect of the cleaning cloth on the cleaning roller 121, increasing the drying efficiency, reducing the electricity consumption required for drying, and improving the energy efficiency ratio of the product; at the same time, this can avoid the cleaning liquid sprayed by the second liquid spray nozzle 221 from entering the air outlet 231.

[0172] Of course, the air outlet 231 of the drying module 230 may also be located inside the roller groove 210. When the second liquid spray nozzle 221 is located in the roller groove 210, the air outlet 231 is located on the opening side of the roller groove 210 relative to the second liquid spray nozzle 221, which can prevent the cleaning liquid sprayed by the second liquid spray nozzle 221 from entering the air outlet 231. In addition, air outlets 231 of the drying module 230 may also be arranged both outside and inside the roller groove 210, i.e., the drying module 230 has multiple air outlets 231.

[0173] In some embodiments, as illustrated in [Fig. 9], a charging interface 128 is disposed on the cleaning device 10; as illustrated in [Fig. 1 1], a charging connector 250 is disposed on the charging station 20. When the cleaning device 10 is replaced on the charging station 20 after use, the charging interface 128 of the cleaning device 10 fits with the charging connector 250 of the charging station 20, thereby enabling the cleaning device 10 to be recharged via the charging station 20, i.e., the charging station 20 performs both the recharging of the cleaning device 10 and the electrical heating of the cleaning liquid.

[0174] As illustrated in [Fig.15], a power adapter 270 is installed in the charging station 20, the power adapter 270 being connected to the charging connector 250 and the heating module 260, in order to supply power to the charging connector 250 and the heating module 260 respectively. By means of a single power adapter 270, the control of the power supply to the heating module 260 and the recharging of the cleaning device 10 is achieved, without adding additional components, thus avoiding increasing the volume of the charging station 20.

[0175] The second liquid spray nozzle 221 may be oriented toward the cleaning roller 121, that is, the second liquid spray nozzle 221 may directly spray the cleaning liquid onto the cleaning roller 121; or, the second liquid spray nozzle 221 may spray the cleaning liquid near the cleaning roller 121, causing the cleaning liquid to splash onto the cleaning roller 121 or flow onto the cleaning roller 121 through other structures, the present disclosure not limiting it, as long as the cleaning of the cleaning roller 121 can be achieved by the cleaning liquid.

[0176] The foregoing description and the embodiments just described are considered exemplary only, the true scope of the present disclosure being defined by the appended claims.
