Description

[0001] The present application relates to the technical field of appliances for environment cleaning, and in particular, to a floor brush, cleaning device, and cleaning system.

[0002] As science and technology develop and living standards improve, household cleaning appliances such as vacuum cleaners and floor washers have become more and more popular and have more and more functions. Using a floor washer as an example, a floor washer has a floor mopping function in addition to a vacuuming function.

[0003] In the relevant art, a floor washer mainly comprises a main unit and a floor brush. The floor brush can suck away dust and debris on a floor by means of a negative pressure suction force generated by the main unit. In addition, the floor brush can be further provided with a floor-mopping roller brush and a water tank. The water tank can supply water to the floor-mopping roller brush so as to humidify the floor-mopping roller brush, or to directly spray water on a floor, before cleaning a floor thoroughly. However, as the floor brush needs to be provided with not only a roller brush, but also a water tank, the volume of the floor brush is relatively large. If a clean water tank is integrated in the roller brush, the volume of the floor brush can be reduced. But how to replenish the clean water tank with water is a problem that urgently needs to be solved.

[0004] In view of the above, the present application provides a floor brush, a cleaning device, and a cleaning system, so as to solve the drawbacks in the relevant art.

[0005] In a first aspect, the present application provides a floor brush, comprising a floor brush body, a roller brush assembly, and a water supply assembly, the roller brush assembly comprising a roller brush and a handle member, the water supply assembly comprising a clean water tank and a first water filling unit, the roller brush being rotatably connected to the handle member, the handle member being connected to the floor brush body, the clean water tank being arranged inside the roller brush; the first water filling unit comprises a water filling valve body and a first water filling valve core, the water filling valve body being connected to the floor brush body, the water filling valve body having a first water filling port and a second water filling port, the handle member having a flow channel, the flow channel being connected between the first water filling port and the clean water tank, the first water filling valve core being movably arranged in the water filling valve body, so as to open or close the second water filling port.

[0006] In the floor brush provided by the present application, by providing the floor brush body for mounting the roller brush assembly and the water supply assembly, providing the handle member for rotatably connecting the roller brush to the floor brush body, providing the roller brush for coming into rotary contact with a floor to be cleaned so as to clean the surface to be cleaned, providing the clean water tank for storing a cleaning liquid, and integrating the clean water tank inside the roller brush, the clean water tank and the roller brush share part of the space, thus reducing the volume of the floor brush. By providing the flow channel for connecting the clean water tank and the first water filling port, so that the cleaning liquid flows into the clean water tank in the roller brush via the flow channel. By providing the first water filling valve core for controlling the state of opening and closing of the second water filling port, so that the second water filling port is opened to allow a cleaning base station to replenish the clean water tank with water, or closed after water replenishment is completed. Thus, the floor brush provided by the present application has a relatively small volume, and is relatively easy to be replenished with water.

[0007] In a possible mode of realization, two sides of the handle member along an advancing direction of the floor brush are connected to the clean water tank and the floor brush body respectively, the flow channel extends along the advancing direction of the floor brush.

[0008] Thus, the handle member can extend along the advancing direction of the floor brush, and the flow channel extending along the advancing direction of the floor brush can be arranged in the handle member. The cleaning liquid flowing out of the first water filling port can flow along the advancing direction of the floor brush before entering the clean water tank.

[0009] In a possible mode of realization, the clean water tank is fixedly connected to the handle member, the roller brush is rotatably connected to the clean water tank, and the handle member is removably connected to the floor brush body.

[0010] Thus, the clean water tank can be fixedly connected to the handle member, thereby preventing the clean water tank from rotating with the roller brush and thus increasing the floor brush's stability and reducing the floor brush's power consumption. Secondly, by rotatably connecting the roller brush to the clean water tank, the roller brush can be rotatably connected to the handle member via the clean water tank, thereby rotatably arranging the roller brush at the floor brush body. Further, by removably connecting the roller brush to the floor brush body, when needed, the roller brush assembly and the clean water tank can be removed as a whole from the floor brush body.

[0011] In a possible mode of realization, the clean water tank comprises a water tank body, a first connecting part, and a second connecting part, the first connecting part and the second connecting part being connected to two ends of the water tank body, the roller brush being rotatably connected to the first connecting part, the second connecting part being fixedly connected to the handle member, the water tank body being connected with the flow channel.

[0012] Thus, the water tank body can be used to store the cleaning liquid, and when needed, water is replenished in the water tank body via the first water filling unit and the flow channel. The first connecting part can be rotatably connected to the roller brush, so that the roller brush is rotatably connected to the clean water tank. The second connecting part is connected to the handle member, so that the clean water tank is fixedly connected to the handle member. Thus, the clean water tank is arranged to be statical relative to the floor brush body, thereby preventing the clean water tank from rotating with the roller brush.

[0013] In a possible mode of realization, the roller brush assembly further comprises a threaded fastener, the second connecting part being located at an end of the water tank body towards the handle member, the second connecting part having a threaded connecting hole and a third water filling port, the water tank body having a water containing cavity, the third water filling port being connected between the water containing cavity and the flow channel; the handle member has a through hole, the threaded fastener passing through the through hole to connect in a threaded way to the threaded connecting hole.

[0014] Thus, the second connecting part can be fixedly connected to the handle member by means of the threaded fastener, so that the clean water tank is fixedly connected to the handle member, thereby preventing the clean water tank from rotating with the roller brush when the roller brush rotates. In addition, after the second connecting part is fixedly connected to the handle member, the water containing cavity of the water tank body can be in communication with the flow channel via the third water filling port, so that the cleaning liquid can enter the water containing cavity via the second water filling port, the first water filling port, the flow channel, and the third water filling port sequentially, so as to replenish the clean water tank with water.

[0015] In a possible mode of realization, the water supply assembly further comprises a detecting unit, the detecting unit comprising a floating member, a magnetic member, and a detecting sensor, the magnetic member being connected to the floating member, the floating member being rotatably arranged in the clean water tank, the detecting sensor being arranged at an outer wall of the clean water tank, the detecting sensor and the magnetic member being arranged correspondingly.

[0016] Thus, when the amount of liquid in the clean water tank is insufficient, the floating member will fall with the fall of the liquid level, so that the magnetic member moves with the floating member towards a direction away from the detecting sensor, and a detecting result is returned to the controller, so as to alert a user to timely replenish the clean water tank with water. Alternatively, when the cleaning base station has fully replenished water in the clean water tank, the floating member will rise with the rise of the liquid level, so that the magnetic member moves with the floating member towards a direction approaching the detecting sensor, and the detecting result is returned to the controller, so as to alert a user that water replenishment has been completed.

[0017] In a possible mode of realization, the floor brush body comprises a side cover, the handle member being removably connected to the side cover, the side cover having a mounting slot, the first water filling unit being arranged at the mounting slot.

[0018] Thus, by mounting the first water filling unit in the mounting slot, the first water filling unit can be mounted to the floor brush body. At the same time, by removably connecting the handle member to the side cover, the handle member can be removably connected to the floor brush body.

[0019] In a possible mode of realization, the water supply assembly further comprises a signal transmitting unit, the signal transmitting unit being electrically connected to the detecting sensor, the signal transmitting unit comprising a metal contact piece and a metal spring pin, one of the metal contact piece and the metal spring pin being connected to the side cover, the other being connected to the handle member, the metal contact piece being electrically connected to the metal spring pin.

[0020] Thus, when the whole assembly composed of the roller brush assembly and the clean water tank is removed from the side cover, the metal contact piece and the metal spring pin are separated from each other, so as to be electrically disconnected. When the whole assembly composed of the roller brush assembly and the clean water tank is mounted to the side cover, the metal contact piece and the metal spring pin come into contact with each other, so as to establish the electrical connection, thereby returning a detecting result of the detecting sensor to the controller by means of the signal transmitting unit.

[0021] In a possible mode of realization, the first water filling unit further comprises a first elastic member, two ends of the first elastic member in the elastic force direction being connected to the first water filling valve body and the first water filling valve core respectively, so as to drive the first water filling valve core to move towards the second water filling port.

[0022] Thus, when the clean water tank has been fully replenished with the cleaning liquid, the floor brush is disengaged from the cleaning base station, so that the lifting member stops abutting against the first water filling valve core and the first elastic member can drive the first water filling valve core to move towards the second water filling port. Thus, the first water filling valve core closes the second water filling port. Alternatively, the lifting member is controlled to retract, so that the lifting member stops abutting against the first water filling valve core, and the first elastic member can drive the first water filling valve core to move towards the second water filling port. Thus, the first water filling valve core closes the second water filling port.

[0023] In a possible mode of realization, the water supply assembly further comprises a second water filling unit, the second water filling unit comprising a second water filling valve core and a second elastic member, the second water filling valve core being movably arranged at an end of the flow channel away from the clean water tank, two ends of the second elastic member in the elastic force direction being connected to the handle member and the second water filling valve core respectively, so as to drive the second water filling valve core to close the flow channel; the side cover is provided with a connector, the handle member being insertion connected into the connector, two ends of the connector being connected (in communication) with the first water filling port and the flow channel respectively, a push rod being provided in the connector, the push rod abutting against the second water filling valve core, so as to drive the second water filling valve core to open the flow channel.

[0024] Thus, when the roller brush assembly is removed, the second water filling valve can be driven by an elastic force of the second elastic member to move towards the connector, so that the second water filling valve core closes the flow channel and thus disconnects the flow channel from the first water filling port, thereby preventing the cleaning liquid of the clean water tank and the flow channel from leaking. When the roller brush assembly is mounted, the handle member can be insertion connected into the connector, so that the push rob abuts against the second water filling valve core and thus drives the second water filling valve core to move away from the connector, so that the second water filling valve core opens the flow channel, thereby connecting the clean water tank, the flow channel, and the first water filling port in sequence.

[0025] In a possible mode of realization, the moving direction of the first water filling valve core points to the bottom surface of the floor brush body, and the moving direction of the second water filling valve core is consistent with the disassembly / assembly direction of the roller brush assembly.

[0026] With such arrangement, when a user places the floor brush at the cleaning base station along the vertical direction or a direction at a certain angle with the vertical direction, the lifting member of the cleaning base station can accurately abut against the first water filling valve core, so as to drive the first water filling valve core to move away from the second water filling port, this prevents the user from having to repeat operations in order to engage the floor brush with the cleaning base station. In addition, when a user mounts the whole assembly composed of the roller brush assembly and the clean water tank to the side cover, the push rod of the side cover can accurately abut against the second water filling valve core, thus opening the flow channel.

[0027] In a possible mode of realization, two roller brushes are provided, the two roller brushes being arranged at intervals along the advancing direction of the floor brush, the clean water tank being arranged in at least one of the roller brushes.

[0028] Thus, when two roller brushes are arranged at intervals along the advancing direction of the floor brush, one roller brush can be used for dry suction, and the other can be used for wet mopping. Alternatively, both roller brushes can be used for wet mopping. With such combination, the floor brush's cleaning effect and cleaning efficiency can be increased. The clean water tank can be arranged in one of the roller brushes. Alternatively, both roller brushes can be provided with a clean water tank, thereby increasing the cleaning liquid capacity of the floor brush and thus improving the floor brush's lasting capacity during wet mopping.

[0029] In a possible mode of realization, the clean water tanks and the roller brushes are arranged in a one-to-one correspondence, the detecting unit being arranged in at least one clean water tank.

[0030] Thus, both roller brushes are provided with a clean water tank inside. As a result, at the same time of increasing the cleaning liquid capacity of the floor brush and thus improving the floor brush's lasting capacity during wet mopping, the clean water tanks will not increase the volume of the floor brush.

[0031] In a possible mode of realization, the two clean water tanks are connected (in communication) with each other, the first water filling unit being connected with one of the two clean water tanks, the detecting unit being arranged at the other of the two clean water tanks.

[0032] Thus, when the floor brush is docked with the cleaning base station, the cleaning base station replenishes one clean water tank with water first, and then replenishes the other clean water tank with water. When the detecting unit detects that the other clean water tank has a relatively high liquid level, it indicates that water replenishment of both clean water tanks has been completed.

[0033] In a possible mode of realization, the water supply assembly further comprises a flow divider, the flow divider having a confluence port and two diverting ports, the confluence port being connected with the first water filling port, the diverting ports being connected with the clean water tanks in a one-to-one correspondence, the detecting units being arranged in a one-to-one correspondence with the clean water tanks.

[0034] Thus, the amounts of liquid in the two clean water tanks can be monitored, so as to send out alerts when the amount of liquid in each clean water tank is insufficient and when each clean water tank has completed water replenishment.

[0035] In a second aspect, the present application provides a cleaning device, comprising a device main unit and the floor brush provided by the first aspect described above, the floor brush being connected to the device main unit.

[0036] In a third aspect, the present application provides a cleaning system, comprising a cleaning base station and the clean device provided by the second aspect described above, the cleaning base station replenishing water for the floor brush when the floor brush is connected to the cleaning base station.

[0037] In a possible mode of realization, the cleaning base station is provided with a lifting member, which is configured to be engaged with the first water filling unit when the floor brush is docked with the cleaning base station for water replenishment.

[0038] In a preferred mode of realization, the lifting member is configured to abut against the first water filling valve core such that the first water filling valve core is driven to move away from the second water filling port, thereby opening the second water filling port.

[0045] The terms "first," "second," and "third" (if any) in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0046] In addition, the terms "comprise / include" and "have," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or display.

[0047] In the relevant art, a floor washer mainly comprises a main unit and a floor brush. The floor brush can suck away dust and debris on a floor by means of negative suction force generated by the main unit. In addition, the floor brush can be provided with a floor-mopping roller brush and a water tank. The water tank can supply water to the floor-mopping roller brush, so as to humidify the floor-mopping roller brush, or to directly spray water to a floor, before cleaning the floor. However, as the floor brush needs to be provided with not only the roller brush but also the water tank, the volume of the floor brush is relatively large. If a clean water tank is integrated in the roller brush, the volume of the floor brush can be reduced. But how to replenish the clean water tank with water is a problem that urgently needs to be solved.

[0048] In view of the problem described above, embodiments of the present application provide a floor brush, cleaning device, and cleaning system, wherein a clean water tank is provided inside a roller brush, so that the clean water tank and the roller brush share part of the space, thereby reducing the size / volume of the floor brush, and when the cleaning device is docked with a cleaning base station, a lifting member of the cleaning base station can lift up (jack up) a first water filling valve core, so that the first water filling valve core opens a second water filling port, so that the cleaning base station can replenish the clean water tank with water.

[0049] Specific modes of realization of the floor brush, cleaning device, and cleaning system provided by embodiments of the present application are described in detail in conjunction with the accompanying drawings.

[0050] In reference to Figs. 1 and 2, an embodiment of the present application provides a cleaning system, comprising a cleaning base station 2 and a cleaning device 1. When the cleaning device 1 is docked with the cleaning base station 2, the cleaning base station 2 replenishes water for the cleaning device 1.

[0051] It should be noted that when the cleaning device 1 is docked with the cleaning base station 2, the cleaning base station 2 can also charge the cleaning device 1. Or, the cleaning base station 2 has a cleaning sink, and the cleaning device 1 can perform self-cleaning operations such as washing and drying in the cleaning sink.

[0052] In reference to Fig. 2, the present application provides a cleaning device 1, comprising a device main unit 20 and a floor brush 10. The floor brush 10 is connected to the device main unit 20.

[0053] The floor brush 10 can be used to come into contact with a surface to be cleaned, so as to clean the surface to be cleaned. The device main unit 20 can supply suction force and power to the floor brush 10, so that when the cleaning device 1 moves relative to the surface to be cleaned, the floor brush 10 can perform operations such as vacuuming and floor mopping on the surface to be cleaned.

[0054] In reference to Figs. 3 to 10, a floor brush 10 provided by an embodiment of the present application comprises a floor brush body 100, a roller brush assembly 200, and a water supply assembly 300. The roller brush assembly 200 comprises a roller brush 210 and a handle member 220. The water supply assembly 300 comprises a clean water tank 310 and a first water filling unit 320. The roller brush 210 is rotatably connected to the handle member 220. The handle member 220 is connected to the floor brush body 100. The clean water tank 310 is arranged inside the roller brush 210.

[0055] The first water filling unit 320 comprises a water filling valve body 321 and a first water filling valve core 322. The water filling valve body 321 is connected to the floor brush body 100. The water filling valve body 321 has a first water filling port 3211 and a second water filling port 3212. The handle member 220 has a flow channel 221. The flow channel 221 is connected between the first water filling port 3211 and the clean water tank 310. The first water filling valve core 322 is movably arranged in the water filling valve body 321, so as to open or close the second water filling port 3212.

[0056] It can be understood that the floor brush body 100 is configured for mounting the roller brush assembly 200, and the roller brush assembly 200 is used to clean a surface to be cleaned. Specifically, the roller brush assembly 200 can comprise the roller brush 210 and the handle member 220. The handle member 220 is configured to connect the roller brush 210 and the floor brush body 100, and then the roller brush 210 is rotatably arranged on the floor brush body 100. When the roller brush 210 rotates, an outer surface of the roller brush 210 is used to come into contact with a surface to be cleaned so as to wipe and wash the surface to be cleaned, or help suck away debris on the surface to be cleaned.

[0057] The water supply assembly 300 comprises a clean water tank 310 and a first water filling unit 320. The clean water tank 310 is configured to store a cleaning liquid so as to supply it to the roller brush 210 or a surface to be cleaned. When the amount of the cleaning liquid in the clean water tank 310 is not enough, the clean water tank 310 needs to be replenished with water by means of the first water filling unit 320.

[0058] Specifically, the first water filling unit 320 can comprise a water filling valve body 321 and a first water filling valve core 322. The water filling valve body 321 has a first water filling port 3211 and a second water filling port 3212. When the clean water tank 310 lacks water, the floor brush 10 can be docked with the cleaning base station 2. The cleaning base station 2 can be provided with a lifting member 21 so as to abut against the first water filling valve core 322 by means of the lifting member 21, thereby driving the first water filling valve core 322 to move away from the second water filling port 3212 and thus opening the second water filling port 3212, which allows the cleaning liquid of the cleaning base station 2 to enter the water filling valve body 321. After the clean water tank 310 has been sufficiently replenished with the cleaning liquid, the floor brush 10 can be disengaged from the cleaning base station 2, so that the lifting member 21 disengages from abutting against the first water filling valve core 322, thereby the first water filling valve core 322 closes the second water filling port 3212, or the lifting member 21 is controlled to retract, so that the lifting member 21 disengages from abutting against the first water filling valve core 322, thereby the first water filling valve core 322 closes the second water filling port 3212.

[0059] As the clean water tank is arranged inside the roller brush 210, the clean water tank 310 and the roller brush 210 can share part of the space. Thus, the overall structure of the floor brush 10 can be rendered more compact, thereby effectively reducing the volume of the floor brush 10. However, as the first water filling unit 320 is arranged outside the roller brush 210 and is not arranged adjacent to the clean water tank 310, the clean water tank 310 cannot be directly connected to the first water filling port 3211. Therefore, in embodiments of the present application, the handle member 220 is provided with a flow channel 221. The flow channel 221 is connected between the clean water tank 310 and the first water filling port 321. Thus, when the second water filling port 3212 opens, the cleaning liquid can enter the clean water tank 310 via, sequentially, the second water filling port 3212, the first water filling port 3211, and the flow channel 221, so as to replenish the clean water tank 310 with water. Thus, it is relatively convenient to replenish the clean water tank 310 with water.

[0060] It should be noted that the water supply assembly 300 can further comprise a water injection member and a driving pump. The water injection member is used to inject the cleaning liquid towards the roller brush 210. The driving pump is used to provide a driving force for the cleaning liquid so as to drive the cleaning liquid in the clean water tank 310 to enter the water injection member via the flow channel 221. The water injection member is configured to inject the cleaning liquid towards the roller brush 210 so as to humidify an outer surface of the roller brush 210 and thus help the roller brush 210 clean thoroughly a surface to be cleaned, or to spray the cleaning liquid towards the roller brush 210 for the roller brush 210 to self-clean.

[0061] The floor brush 10 provided by the embodiment of the present application comprises the floor brush body 100, the roller brush assembly 200, and the water supply assembly 300. The roller brush assembly 200 comprises the roller brush 210 and the handle member 220. The water supply assembly 300 comprises the clean water tank 310 and the first water filling unit 320. The first water filling unit 320 comprises the water filling valve body 321 and the first water filling valve core 322. The water filling valve body 321 comprises the first water filling port 3211 and the second water filling port 3212. By providing the floor brush body 100 for mounting the roller brush assembly 200 and the water supply assembly 300, providing the handle member 220 for rotatably connecting the roller brush 210 to the floor brush body 100, providing the roller brush 210 for rolling contact with a surface to be cleaned so as to clean the surface to be cleaned, providing the clean water tank 310 for storing a cleaning liquid, and integrating the clean water tank 310 inside the roller brush 210, the clean water tank 310 and the roller brush 210 share part of the space, thus reducing the volume of the floor brush 10. By providing the flow channel 221 for connecting the clean water tank 310 with the first water filling port 3211, the cleaning liquid flows into the clean water tank 310 in the roller brush 210 via the flow channel 221. By providing the first water filling valve core 322 for controlling the state of opening and closing of the second water filling port 3212, the second water filling port 3212 is opened to allow the cleaning base station 2 to replenish the clean water tank 310 with water, or closed after water replenishment is completed. Thus, the floor brush 10 provided by the embodiment of the present application has a relatively small volume, and is relatively easy to be replenished with water.

[0062] In a possible mode of realization, two sides of the handle member 220 along the advancing direction of the floor brush 10 are connected to the clean water tank 310 and the floor brush body 100 respectively. The flow channel 221 extends along the advancing direction of the floor brush 10.

[0063] It can be understood that the roller brush 210 can be arranged at the front end or rear end of the floor brush body 100 along the advancing direction of the floor brush 10. As the clean water tank 310 is located inside the roller brush 210, the clean water tank 310 is also located at an end of the advancing direction of the floor brush 10. The first water filling unit 320 can be arranged in a middle part of the floor brush body 100 along the advancing direction of the floor brush 100, so as to engage with the lifting member 21 of the cleaning base station 2. Thus, the handle member 220 can extend along the advancing direction of the floor brush 10, and the flow channel 221 extending along the advancing direction of the floor brush 10 can be arranged inside the handle member 220. In this way, the cleaning liquid flowing out of the first water filling port 3211 can flow along the advancing direction of the floor brush 10 and then enter the clean water tank 310.

[0064] As the cleaning liquid in the clean water tank 310 cannot maintain a fixed shape, and the volume of the cleaning liquid will gradually decrease as cleaning work progresses, if the clean water tank 310 rotates with the roller brush 210, the cleaning liquid will shake greatly inside the clean water tank 310, thus rendering the floor brush 10 unstable during use. In addition, compared to driving only the roller brush 210 itself to rotate, driving the roller brush 210 and the clean water tank 310 to rotate together needs more energy consumption, thereby increasing the floor brush 10's ineffective power consumption. Therefore, in a possible mode of realization, the clean water tank 310 is fixedly connected to the handle member 220, the roller brush 210 is rotatably connected to the clean water tank 310, and the handle member 220 is removably connected to the floor brush body 100.

[0065] In the above configuration, first, the clean water tank 310 can be fixedly connected to the handle member 220, thereby preventing the clean water tank 310 from rotating with the roller brush 210 and thus increasing the floor brush 10's stability and reducing the floor brush 10's power consumption. Second, by rotatably connecting the roller brush 210 to the clean water tank 310, the roller brush 210 can be rotatably connected to the handle member 220 via the clean water tank 310, so that the roller brush 210 is rotatably arranged on the floor brush body 100. Further, by removably connecting the roller brush 210 to the floor brush body 100, when needed, the roller brush assembly 200 and the clean water tank 310 is removed from the floor brush body 100 as a whole.

[0066] In reference to Figs. 11 and 12, in specific implementations, the clean water tank 310 comprises a water tank body 311, a first connecting part 312, and a second connecting part 313. The first connecting part 312 and the second connecting part 313 are connected to two ends of the water tank body 311. The roller brush 210 is rotatably connected to the first connecting part 312. The second connecting part 313 is fixedly connected to the handle member 220. The water tank body 311 is connected to (in communication with) the flow channel 221.

[0067] Thus, the water tank body 311 can be used to store the cleaning liquid, and when needed, the water tank body 311 is replenished with water via the first water filling unit 320 and the flow channel 221. The first connecting part 312 can be rotatably connected to the roller brush 210, so that the roller brush 210 is rotatably connected to the clean water tank 310. The second connecting part 313 is connected to the handle member 220, so that the clean water tank 310 is fixedly connected to the handle member 220. Thus, the clean water tank 310 is arranged to be statical relative to the floor brush body 100, thereby preventing the clean water tank 310 from rotating with the roller brush 210.

[0068] In reference to Figs. 8 and 12, in a possible mode of realization, the roller brush assembly 200 further comprises a threaded fastener 230. The second connecting part 313 is located at an end of the water tank body 311 towards the handle member 220. The second connecting part 313 has a threaded connecting hole 3131 and a third water filling port 3132. The water tank body 311 has a water containing cavity 3111. The third water filling port 3132 is connected between the water containing cavity 3111 and the flow channel 221 in communication. The handle member 220 has a through hole 222. The threaded fastener 230 passes through the through hole 222 to connect in a threaded way to the threaded connecting hole 3131.

[0069] With such configuration, the second connecting part 313 can be fixedly connected to the handle member 220 by means of the threaded fastener 230, so that the clean water tank 310 is fixedly connected to the handle member 220, thereby preventing the clean water tank 310 from rotating with the roller brush 210 when the roller brush 210 rotates. In addition, after the second connecting part 313 is fixedly connected to the handle member 220, the water containing cavity 3111 of the water tank body 311 can be in communication with the flow channel 221 via the third water filling port 3132, so that the cleaning liquid can enter the water containing cavity 3111 via the second water filling port 3212, the first water filling port 3211, the flow channel 221, and the third water filling port 3132 sequentially, so as to replenish the clean water tank 310 with water.

[0070] In reference to Figs. 11 to 13, in order to detect the amount of liquid in the clean water tank 310, in some modes of realization, the water supply assembly 300 further comprises a detecting unit 330. The detecting unit 330 comprises a floating member 331, a magnetic member 332, and a detecting sensor 333. The magnetic member 332 is connected to the floating member 331. The floating member 331 is rotatably arranged in the clean water tank 310. The detecting sensor 333 is arranged on an outer wall of the clean water tank 310, the detecting sensor 333 and the magnetic member 332 are arranged correspondingly.

[0071] It can be understood that the floating member 331 will swing with the change of the liquid level. The detecting sensor 333 can detect the change of the liquid level by detecting the relative position change of the magnetic member 332. Thus, when the amount of liquid in the clean water tank 310 is insufficient, the floating member 331 will fall with the fall of the liquid level, then the magnetic member 332 moves with the floating member 331 towards a direction away from the detecting sensor 333, and the detecting result is returned to a controller, so as to alert a user to timely replenish the clean water tank 310 with water.

[0072] Alternatively, when the cleaning base station 2 has fully replenished the clean water tank 310 with water, the floating member 331 will rise with the rise of the liquid level, so that the magnetic member 332 moves with the floating member 331 towards a direction approaching the detecting sensor 333, and a detecting result is returned to the controller, so as to alert a user that water replenishment has been completed.

[0073] Wherein the controller can be arranged at one of the floor brush 10, the device main unit 20, and the cleaning base station 2.

[0074] In a possible mode of realization, the floor brush body 100 comprises a side cover 110. The handle member 220 is removably connected to the side cover 110. The side cover 110 has a mounting slot 111. The first water filling unit 320 is arranged at the mounting slot 111.

[0075] Thus, by mounting the first water filling unit 320 in the mounting slot 111, the first water filling unit 320 can be mounted to the floor brush body 100. At the same time, by removably connecting the handle member 220 to the side cover 110, the handle member 220 can be removably connected to the floor brush body 100.

[0076] In reference to Figs. 5 and 14 to 16, in some embodiments, the water supply assembly 300 further comprises a signal transmitting unit 340. The signal transmitting unit 340 is electrically connected to the detecting sensor 333. The signal transmitting unit 340 comprises a metal contact piece 341 and a metal spring pin 342. One of the metal contact piece 341 and the metal spring pin 342 is connected to the side cover 110, the other is connected to the handle member 220. The metal contact piece 341 is electrically connected to the metal spring pin 342.

[0077] It can be understood that as the roller brush assembly 200 and the clean water tank 310 are removably connected to the side cover 110, and the detecting unit 330 is arranged at the clean water tank 310, detecting results of the detecting unit 330 need to be returned to the controller in a flexible way. In the above configuration, when the whole assembly composed of the roller brush assembly and the clean water tank 310 is removed from the side cover 110, the metal contact piece 341 and the metal spring pin 342 are separated from each other, thereby disconnecting the electrical connection. When the whole assembly composed of the roller brush assembly and the clean water tank 310 is mounted on the side cover 110, the metal contact piece 341 and the metal spring pin 342 come into contact with each other, thereby establishing the electrical connection, so that the detection result of the detecting sensor 333 is fed back to the controller by means of the signal transmitting unit 340.

[0078] By way of example, the metal contact piece 341 is arranged at the side cover 110, and the metal spring pin 342 is arranged at the handle member 220. The metal spring pin 342 can be connected to the detecting sensor 333 through a wire. The metal contact piece 341 is electrically connected to the metal spring pin 342. Alternatively, the metal spring pin 342 is arranged at the side cover 110, and the metal contact piece 341 is arranged at the handle member 220. The metal contact piece 341 can be connected to the detecting sensor 333 through a wire, and the metal spring pin 342 is electrically connected to the metal contact piece 341.

[0079] In addition, in order to improve the reliability of the signal transmitting unit 340, three groups of metal contact piece 341 and three metal spring pins 342 can be provided. The metal contact pieces 341 and the metal spring pins 342 are arranged in a manner of one-to-one correspondence.

[0080] In reference to Figs. 9 and 10, in a possible mode of realization, the first water filling unit 320 further comprises a first elastic member 323. Two ends of the first elastic member 323 in the elastic force direction are connected to the first water filling valve body 321 and the first water filling valve core 322 respectively, so as to drive the first water filling valve core 322 to move towards the second water filling port 3212.

[0081] Thus, when the clean water tank 310 has been fully replenished with the cleaning liquid, the floor brush 10 disengages from the cleaning base station 2, so that the lifting member 21 disengages from abutting against the first water filling valve core 322, and the first elastic member 323 can drive the first water filling valve core 322 to move towards the second water filling port 3212. Thus, the first water filling valve core 322 closes the second water filling port 3212. Alternatively, the lifting member 21 is controlled to retract, so that the lifting member 21 disengages from abutting against the first water filling valve core 322, and the first elastic member 323 can drive the first water filling valve core 322 to move towards the second water filling port 3212. Thus, the first water filling valve core 322 closes the second water filling port 3212.

[0082] In reference to Figs. 17 and 18, in some modes of realization, the water supply assembly 300 further comprises a second water filling unit 350. The second water filling unit 350 comprises a second water filling valve core 351 and a second elastic member 352. The second water filling valve core 351 is movably arranged at an end of the flow channel 221 away from the clean water tank 310. Two ends of the second elastic member 352 in the elastic force direction are connected to the handle member 220 and the second water filling valve core 351 respectively, so as to drive the second water filling valve core 351 to close the flow channel 221.

[0083] The side cover 110 is provided with a connector 112. The handle member 220 is insertion connected to the connector 112. Two ends of the connector 112 are connected (in communication) with the first water filling port 3211 and the flow channel 221 respectively. A push rod 1121 is provided in the connector 112. The push rod 1121 abuts against the second water filling valve core 351, so as to drive the second water filling valve core 351 to open the flow channel 221.

[0084] Thus, when the roller brush assembly 200 is removed, the second water filling valve core can be driven by an elastic force of the second elastic member 352 to move towards the connector 112, so that the second water filling valve core 351 closes the flow channel 221 and thus disconnects the flow channel 221 and the first water filling port 3211, thereby preventing the cleaning liquid in the clean water tank 310 and the flow channel 221 from leaking.

[0085] When the roller brush assembly 200 is mounted, the handle member 220 can be insertion connected to (plugged into) the connector 112, so that the push rod 1121 abuts against the second water filling valve core 351 and thus drives the second water filling valve core 351 to move away from the connector 112, so that the second water filling valve core 351 opens the flow channel 221, thereby enabling the clean water tank 310, the flow channel 221, and the first water filling port 3211 to be connected (in communication) sequentially.

[0086] In a possible mode of realization, the moving direction of the first water filling valve core 322 points to the bottom surface of the floor brush body 100, and the moving direction of the second water filling valve core 351 is consistent with the disassembly and assembly direction of the roller brush assembly 200.

[0087] With such arrangement, when a user places the floor brush 10 at the cleaning base station 2 along a vertical direction or a direction at a certain angle with the vertical direction, the lifting member 21 of the cleaning base station 2 can accurately abut against the first water filling valve core 322, so as to drive the first water filling valve core 322 to move away from the second water filling port 3212, this prevents the user from having to repeat operations to properly dock the floor brush 10 at the cleaning base station 2. In addition, when a user mounts the whole assembly composed of the roller brush assembly 200 and the clean water tank 310 to the side cover 110, the push rod of the side cover 110 can accurately abut against the second water filling valve core 351, thereby opening the flow channel 221.

[0088] By way of example, the moving direction of the first water filling valve core 322 can be perpendicular to the bottom surface of the floor brush 10, and the moving direction of the second water filling valve core 351 can be consistent with the axial direction of the roller brush 210.

[0089] In a possible mode of realization, there are two roller brushes 210. The two roller brushes 210 are arranged at intervals along the advancing direction of the floor brush 10. The clean water tank 310 is arranged in at least one of the roller brushes 210.

[0090] It should be noted that, when two roller brushes 210 are arranged at intervals along the advancing direction of the floor brush 10, one roller brush 210 can be used for dry suction, and the other can be used for wet mopping. Alternatively, both roller brushes 210 can be used for wet mopping. With such combination, the floor brush 10's cleaning effect and cleaning efficiency can be increased. In the above arrangement, the clean water tank 310 can be arranged in one of the roller brushes 210. Alternatively, both roller brushes 210 can be provided with a clean water tank 310, thereby increasing the cleaning liquid capacity of the floor brush 10 and thus improving the floor brush 10's lasting capacity during wet mopping.

[0091] In some modes of realization, the clean water tanks 310 and the roller brushes 210 are arranged in a one-to-one correspondence, the detecting unit 330 being arranged in at least one clean water tank 310.

[0092] Thus, both roller brushes 210 are provided with a clean water tank 310 inside. As a result, at the same time of increasing the cleaning liquid capacity of the floor brush 10 and thus improving the floor brush 10's lasting capacity during wet mopping, the clean water tanks 310 will not increase the volume of the floor brush 10.

[0093] It should be noted that, the detecting unit 330 can be arranged at one of the two clean water tanks 310. The two clean water tanks 310 can communicate with each other. Thus, by detecting the amount of liquid in one clean water tank 310 by means of a detecting unit 330, whether the two clean water tanks have completed water replenishment at the same time is detected, thereby saving the floor brush 10's costs. Alternatively, both clean water tanks 310 can be provided with a detecting unit 330. Thus, the amounts of liquid in the corresponding clean water tanks 310 are detected by means of the detecting units 330, so as to send out alerts when the amount of liquid in a clean water tank 310 is insufficient and when water replenishment is completed.

[0094] In a possible mode of realization, the two clean water tanks 310 are in communication with each other. The first water filling unit 320 is connected in communication with one of the two clean water tanks 310, and the detecting unit 330 is arranged at the other of the two clean water tanks 310.

[0095] In other words, the two clean water tanks 310 can comprise a first clean water tank 310 and a second clean water tank 310. The first water filling unit 320 is connected in communication with the first clean water tank 310. The detecting unit 330 can be arranged at the second clean water tank 310. When the floor brush 10 docks with the cleaning base station 2, the cleaning base station 2 replenishes the first clean water tank 310 with water first, and then replenishes the second clean water tank 310 with water. When the detecting unit 330 detects that the second clean water tank 310 has a relatively high liquid level, it indicates that water replenishment of the first clean water tank and the second clean water tank 310 has been completed.

[0096] In reference to Fig. 19, in a possible mode of realization, the water supply assembly 300 further comprises a flow divider 360. The flow divider 360 has a confluence port 361 and two diverting ports 362. The confluence port 361 is connected in communication with the first water filling port 3211. The diverting ports 362 are connected in communication with the clean water tanks 310 in a one-to-one correspondence. The detecting units 330 are arranged in a one-to-one correspondence with the clean water tanks 310.

[0097] With such arrangement, the amounts of liquid in the two clean water tanks 310 can be monitored, so as to send out alerts when the amount of liquid in each clean water tank 310 is insufficient and when each clean water tank 310 has completed water replenishment.

[0098] It should be noted that the diameters of the two diverting ports 362 can be the same, so that cleaning liquid entering the flow divider 360 can be evenly distributed to the two clean water tanks 310.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to depart from the scope of the technical solutions of the embodiments of the present application.
