Description

Technical Field

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

[0002] With the development of science and technology and the improvement of living standards, household cleaning appliances such as vacuum cleaners and floor scrubbers have become more and more popular, and their functions are becoming more and more numerous. Take floor scrubbers as an example. In addition to vacuuming, floor scrubbers also have the function of mopping the floor.

[0003] In the related art, a floor scrubber mainly includes a main unit and a floor brush. The floor brush can absorb dust and impurities on the ground through the negative pressure suction generated by the main unit. In addition, the floor brush can also be provided with a mopping roller brush and a water tank. The water tank can supply water to the mopping roller brush to wet the mopping roller brush, or directly spray water on the ground to perform a deep cleaning on the ground. However, since the floor brush not only needs to be arranged with a roller brush but also a water tank, the volume of the floor brush is relatively large. If the 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 is a problem that needs to be solved urgently. Utility Model Content

[0004] Based on this, the present application provides a floor brush, a cleaning device and a cleaning system to solve the deficiencies in the related 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, wherein the roller brush assembly comprises a roller brush and a handle, the water supply assembly comprises a clean water tank and a first water injection unit, the roller brush is rotatably connected to the handle, the handle is connected to the floor brush body, and the clean water tank is arranged in the roller brush;

[0006] The first water injection unit includes a water injection valve body and a first water injection valve core. The water injection valve body is connected to the floor brush body. The water injection valve body has a first water injection port and a second water injection port. The handle has a flow channel, and the flow channel is connected between the first water injection port and the clean water tank. The first water injection valve core is movably arranged in the water injection valve body to open or close the second water injection port.

[0007] The floor brush provided by the present application is used to install the roller brush assembly and the water supply assembly through the floor brush body, and is used to rotatably connect the roller brush to the floor brush body by providing a handle, and is used to roll the roller brush in contact with the surface to be cleaned to clean the surface to be cleaned by providing a clean water tank for storing cleaning liquid, and is integrated into the roller brush so that the clean water tank and the roller brush share part of the space, thereby reducing the volume of the floor brush, and is used to connect the clean water tank and the first water injection port by providing a flow channel so that the cleaning liquid enters the clean water tank in the roller brush through the flow channel, and is used to control the opening and closing state of the second water injection port by providing a first water injection valve core, thereby opening the second water injection port so that the cleaning base station replenishes water to the clean water tank, or closing the second water injection port after the water replenishment is completed. Therefore, the floor brush provided by the present application is small in size and is more convenient to replenish water.

[0008] In a possible implementation, two sides of the handle along the travel direction of the floor brush are respectively connected to the clean water tank and the floor brush body, and the flow channel extends along the travel direction of the floor brush.

[0009] In this way, the handle can be extended along the moving direction of the floor brush, and a flow channel extending along the moving direction of the floor brush is set in the handle, and the cleaning liquid flowing out of the first water injection port can flow along the moving direction of the floor brush and then enter the clean water tank.

[0010] In a possible implementation, the clean water tank is fixedly connected to the handle, the roller brush is rotatably connected to the clean water tank, and the handle is detachably connected to the floor brush body.

[0011] In this way, the clean water tank can be fixedly connected to the handle, thereby preventing the clean water tank from rotating with the roller brush, thereby improving the stability of the floor brush and reducing the power consumption of the floor brush. Secondly, the roller brush can be rotatably connected to the clean water tank, so that the roller brush can be rotatably connected to the handle through the clean water tank, and then the roller brush can be rotatably set on the floor brush body. Thirdly, the roller brush is detachably connected to the floor brush body, so that when needed, the roller brush assembly and the clean water tank can be removed from the floor brush body as a whole.

[0012] In one possible implementation, the clean water tank includes a water tank body, a first connecting part and a second connecting part, the first connecting part and the second connecting part are connected to both ends of the water tank body, the roller brush is rotatably connected to the first connecting part, the second connecting part is fixedly connected to the handle, and the water tank body is connected to the flow channel.

[0013] In this way, the water tank body can be used to store cleaning liquid, and when needed, the water tank body can be replenished with water through the first water injection unit and the inner 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, and the second connecting part is connected to the handle piece, so that the clean water tank is fixedly connected to the handle piece, and the clean water tank is statically arranged relative to the floor brush body, thereby preventing the clean water tank from rotating with the roller brush.

[0014] In a possible implementation, the roller brush assembly further includes a threaded fastener, the second connecting portion is located at one end of the water tank body facing the handle, the second connecting portion has a threaded connecting hole and a third water injection port, the water tank body has a water containing cavity, and the third water injection port is connected between the water containing cavity and the flow channel;

[0015] The handle piece has a through hole, and the threaded fastener passes through the through hole to be threadedly connected with the threaded connection hole.

[0016] In this way, the second connection part can be fixedly connected to the handle member through a threaded fastener, thereby making the clean water tank fixedly connected to the handle member, thereby preventing the clean water tank from rotating with the roller brush when the roller brush rotates. After the second connection part is fixedly connected to the handle member, the water storage chamber of the water tank body can be connected to the flow channel through the third water injection port, thereby making the cleaning liquid enter the water storage chamber through the second water injection port, the first water injection port, the flow channel and the third water injection port in sequence, thereby replenishing the clean water tank with water.

[0017] In one possible implementation, the water supply component also includes a detection unit, which includes a floating part, a magnetic part and a detection sensor. The magnetic part is connected to the floating part, the floating part is rotatably arranged in the clean water tank, the detection sensor is arranged on the outer wall of the clean water tank, and the detection sensor and the magnetic part are arranged correspondingly.

[0018] In this way, when the amount of liquid in the clean water tank is insufficient, the floating part will drop as the liquid level drops, causing the magnetic part to follow the floating part to move away from the detection sensor, and feedback the detection result to the controller to remind the user to refill the clean water tank in time. Alternatively, when the cleaning base station fills the clean water tank with water, the floating part will rise as the liquid level rises, causing the magnetic part to follow the floating part to move toward the detection sensor, and feedback the detection result to the controller to remind the user that the water refilling is completed.

[0019] In a possible implementation, the floor brush body includes a side cover, the handle is detachably connected to the side cover, the side cover has a mounting groove, and the first water injection unit is arranged in the mounting groove.

[0020] In this way, the first water injection unit can be installed in the installation groove and then installed to the floor brush body, and the handle can be detachably connected to the side cover to make the handle detachably connected to the floor brush body.

[0021] In a possible implementation, the water supply component also includes a signal transmission unit, which is electrically connected to the detection sensor. The signal transmission unit includes a metal contact and a metal spring needle. One of the metal contact and the metal spring needle is connected to the side cover, and the other is connected to the handle. The metal contact is electrically connected to the metal spring needle.

[0022] In this way, when the roller comb assembly and the clean water tank are removed from the side cover, the metal contact and the metal spring pin are separated, thereby disconnecting the electrical connection. When the roller comb assembly and the clean water tank are installed to the side cover, the metal contact and the metal spring pin are in contact, thereby establishing an electrical connection, thereby feeding back the detection structure of the detection sensor to the controller through the signal transmission unit.

[0023] In a possible implementation, the first water injection unit further includes a first elastic member, and two ends of the first elastic member in the elastic force direction are respectively connected to the first water injection valve body and the first water injection valve core to drive the first water injection valve core to move toward the second water injection port.

[0024] In this way, after the clean water tank is replenished with cleaning liquid, the floor brush is disengaged from the docking station so that the lifting member is disengaged from the abutment with the first water injection valve core, and the first elastic member can drive the first water injection valve core to move toward the second water injection port, thereby causing the first water injection valve core to close the second water injection port. Alternatively, the lifting member is controlled to retract, thereby causing the lifting member to disengage from the abutment with the first water injection valve core, and the first elastic member can drive the first water injection valve core to move toward the second water injection port, thereby causing the first water injection valve core to close the second water injection port.

[0025] In a possible implementation, the water supply assembly further includes a second water injection unit, the second water injection unit includes a second water injection valve core and a second elastic member, the second water injection valve core can be movably arranged at an end of the flow channel away from the clean water tank, and the two ends of the elastic force direction of the second elastic member are respectively connected to the handle member and the second water injection valve core to drive the second water injection valve core to close the flow channel;

[0026] The side cover is provided with a connector, the handle is plugged into the connector, the two ends of the connector are respectively connected to the first water inlet and the flow channel, a push rod is provided in the connector, the push rod abuts against the second water injection valve core to drive the second water injection valve core to open the flow channel.

[0027] In this way, when disassembling the roller brush assembly, the elastic force of the second elastic member can drive the second water injection valve to move toward the connector, so that the second water injection valve core closes the flow channel, and then disconnects the flow channel and the first water injection port, thereby preventing the clean liquid in the clean water tank and the flow channel from leaking. When installing the roller brush assembly, the handle member can be plugged into the connector, so that the push rod abuts against the second water injection valve core, and then drives the second water injection valve core to move away from the connector, so that the second water injection valve core opens the flow channel, so that the clean water tank, the flow channel and the first water injection port are connected in sequence.

[0028] In a possible implementation, the moving direction of the first water injection valve core points to the bottom surface of the floor brush body, and the moving direction of the second water injection valve core is consistent with the disassembly and assembly direction of the roller brush assembly.

[0029] This arrangement allows the user to place the floor brush on the cleaning base station in a vertical direction or in a direction at a certain angle to the vertical direction, so that the lifting part of the cleaning base station can accurately abut against the first water injection valve core, thereby driving the first water injection valve core to move away from the second water injection port, thereby preventing the user from having to repeatedly operate to dock the floor brush with the cleaning base station. And when the user installs the roller brush assembly and the clean water tank as a whole to the side cover, the ejector pin of the side cover can accurately abut against the second water injection valve core, thereby opening the flow channel.

[0030] In a possible implementation, there are two roller brushes, which are spaced apart along the travel direction of the floor brush, and at least one roller brush is provided with a clean water tank.

[0031] In this way, when two roller brushes are arranged at intervals along the moving direction of the floor brush, one roller brush can be used for dry suction and the other roller brush can be used for wet mopping, or both roller brushes can be used for wet mopping. Such a combination can improve the cleaning effect and cleaning efficiency of the floor brush. The clean water tank can be arranged in one of the roller brushes, or clean water tanks can be arranged in both roller brushes, thereby increasing the cleaning liquid capacity of the floor brush and thereby improving the endurance of the floor brush when wet mopping.

[0032] In a possible implementation, the clean water tank and the roller brush are arranged in a one-to-one correspondence, and the detection unit is arranged in at least one of the clean water tanks.

[0033] In this way, clean water tanks are provided in both roller brushes, thereby increasing the cleaning liquid capacity of the floor brushes and thus improving the endurance of the floor brushes during wet mopping. At the same time, the clean water tanks will not increase the volume of the floor brushes.

[0034] In a possible implementation, the two clean water tanks are connected to each other, the first water injection unit is connected to one of the two clean water tanks, and the detection unit is disposed at the other of the two clean water tanks.

[0035] In this way, when the floor brush is docked with the cleaning base station, the cleaning base station first refills one clean water tank with water, and then refills the other clean water tank with water. When the detection unit detects that the liquid level in the other clean water tank is higher, it indicates that both clean water tanks have been refilled.

[0036] In a possible implementation, the water supply assembly also includes a diverter having a confluence port and two diverter ports, the confluence port is connected to the first water inlet, the diverter ports are connected to the clean water tank in a one-to-one correspondence, and the detection unit and the clean water tank are arranged in a one-to-one correspondence.

[0037] In this way, it is convenient to monitor the liquid levels of the two clean water tanks, so as to issue a reminder when the liquid level in each clean water tank is insufficient, and to issue a reminder when the water refilling of each clean water tank is completed.

[0038] In a second aspect, the present application provides a cleaning device, including a device host and the floor brush provided in the first aspect, wherein the floor brush is connected to the device host.

[0039] In a third aspect, the present application provides a cleaning system, including a cleaning base station and the cleaning device provided in the second aspect above. When the floor brush is docked with the cleaning base station, the cleaning base station replenishes water for the floor brush.

[0072] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above-mentioned 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 application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0073] In addition, the terms "comprises," "comprising," and "having," 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 elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0074] In the related art, a floor scrubber mainly includes a main unit and a floor brush. The floor brush can absorb dust and impurities on the ground through the negative pressure suction generated by the main unit. In addition, the floor brush can also be provided with a mopping roller brush and a water tank. The water tank can supply water to the mopping roller brush to wet the mopping roller brush, or directly spray water on the ground to perform a deep cleaning on the ground. However, since the floor brush not only needs to be arranged with a roller brush but also a water tank, the volume of the floor brush is relatively large. If the 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 is a problem that needs to be solved urgently.

[0075] In view of the above problems, an embodiment of the present application provides a floor brush, a cleaning device and a cleaning system, wherein a clean water tank is arranged inside the roller brush so that the clean water tank and the roller brush share part of the space, thereby reducing the volume of the floor brush, and when the cleaning device is docked with the cleaning base station, the lifting part of the cleaning base station can lift the first water injection valve core, thereby allowing the first water injection valve core to open the second water injection port, so that the cleaning base station replenishes water to the clean water tank.

[0076] The specific implementation of the floor brush, cleaning device and cleaning system provided in the embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0077] Reference Figure 1 and Figure 2 As shown, an embodiment of the present application provides a cleaning system including 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 .

[0078] 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 tank, and the cleaning device 1 can perform self-cleaning operations such as washing and drying in the cleaning tank.

[0079] Reference Figure 2As shown, the present application provides a cleaning device 1 , including a device host 20 and a floor brush 10 , wherein the floor brush 10 is connected to the device host 20 .

[0080] Among them, the floor brush 10 can be used to contact the surface to be cleaned and then clean the surface to be cleaned. The device host 20 can provide suction force and electricity 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 mopping the surface to be cleaned.

[0081] Reference Figures 3 to 10 As shown, the floor brush 10 provided in the embodiment of the present application includes a floor brush body 100, a roller brush assembly 200 and a water supply assembly 300, the roller brush assembly 200 includes a roller brush 210 and a handle 220, the water supply assembly 300 includes a clean water tank 310 and a first water injection unit 320, the roller brush 210 is rotatably connected to the handle 220, the handle 220 is connected to the floor brush body 100, and the clean water tank 310 is arranged in the roller brush 210.

[0082] The first water injection unit 320 includes a water injection valve body 321 and a first water injection valve core 322. The water injection valve body 321 is connected to the floor brush body 100. The water injection valve body 321 has a first water injection port 3211 and a second water injection port 3212. The handle 220 has a flow channel 221. The flow channel 221 is connected between the first water injection port 3211 and the clean water tank 310. The first water injection valve core 322 is movably arranged in the water injection valve body 321 to open or close the second water injection port 3212.

[0083] It can be understood that the floor brush body 100 is used to install the roller brush assembly 200, and the roller brush assembly 200 is used to clean the surface to be cleaned. Specifically, the roller brush assembly 200 may include a roller brush 210 and a handle 220. The handle 220 is used to connect the roller brush 210 and the floor brush body 100, and then the roller brush 210 is rotatably set on the floor brush body 100. When the roller brush 210 rotates, the outer surface of the roller brush 210 is used to contact the surface to be cleaned, and then scrub the surface to be cleaned, or assist in sucking away dirt on the surface to be cleaned.

[0084] The water supply assembly 300 includes a clean water tank 310 and a first water injection unit 320, wherein the clean water tank 310 is used to store cleaning liquid to provide it to the roller brush 210 or the surface to be cleaned. When the amount of cleaning liquid in the clean water tank 310 is insufficient, the clean water tank 310 needs to be replenished with water through the first water injection unit 320.

[0085] Specifically, the first water injection unit 320 may include a water injection valve body 321 and a first water injection valve core 322. The water injection valve body 321 has a first water injection port 3211 and a second water injection port 3212. When the clean water tank 310 is short of 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 to abut against the first water injection valve core 322 through the lifting member 21, thereby driving the first water injection valve core 322 to move away from the second water injection port 3212, and then opening the second water injection port 3212, so that the cleaning liquid of the cleaning base station 2 can enter the water injection valve body 321. When the clean water tank 310 is replenished with cleaning liquid, the floor brush 10 can be detached from the cleaning base station 2, so that the lifting member 21 can be detached from the abutment with the first water injection valve core 322, thereby causing the first water injection valve core 322 to close the second water injection port 3212, or the lifting member 21 can be controlled to retract, thereby causing the lifting member 21 to be detached from the abutment with the first water injection valve core 322, thereby causing the first water injection valve core 322 to close the second water injection port 3212.

[0086] Since the clean water tank 310 is arranged inside the roller brush 210, the clean water tank 310 and the roller brush 210 can share part of the space, thereby making the overall structure of the floor brush 10 more compact, thereby effectively reducing the volume of the floor brush 10. However, the first water injection unit 320 is arranged outside the roller brush 210 and is not arranged adjacent to the clean water tank 310, and the clean water tank 310 cannot be directly connected to the first water injection port 3211. Therefore, in the embodiment of the present application, the handle 220 is provided with a flow channel 221, and the flow channel 221 is connected between the clean water tank 310 and the first water injection port 3211. Then, when the second water injection port 3212 is opened, the cleaning liquid can enter the clean water tank 310 through the second water injection port 3212, the first water injection port 3211 and the flow channel 221 in sequence, thereby replenishing the clean water tank 310. Therefore, it is convenient to replenish the clean water tank 310.

[0087] It should be noted that the water supply component 300 may also include a water spray component and a driving pump. The water spray component is used to spray cleaning liquid onto the roller brush 210, and the driving pump is used to provide driving force for the cleaning liquid, thereby driving the cleaning liquid in the clean water tank 310 into the water spray component through the flow channel 221. The water spray component is used to spray cleaning liquid onto the roller brush 210 to wet the outer surface of the roller brush 210, thereby facilitating the roller brush 210 to deeply clean the surface to be cleaned, or, by spraying cleaning liquid onto the roller brush 210, the roller brush 210 can be self-cleaned.

[0088] The floor brush 10 provided in the embodiment of the present application includes a floor brush body 100, a roller brush assembly 200 and a water supply assembly 300, the roller brush assembly 200 includes a roller brush 210 and a handle 220, the water supply assembly 300 includes a clean water tank 310 and a first water injection unit 320, the first water injection unit 320 includes a water injection valve body 321 and a first water injection valve core 322, and the water injection valve body 321 includes a first water injection port 3211 and a second water injection port 3212. The floor brush body 100 is used to install the roller brush assembly 200 and the water supply assembly 300, the handle 220 is provided to rotatably connect the roller brush 210 to the floor brush body 100, the roller brush 210 is provided to roll in contact with the surface to be cleaned to clean the surface to be cleaned, the clean water tank 310 is provided to store cleaning liquid, the clean water tank 310 is integrated in the roller brush 210 so that the clean water tank 310 and the roller brush 210 share part of the space, thereby reducing the volume of the floor brush 10, and the flow channel 221 is provided to connect the clean water tank 310 and the first water injection port 3211 so that the cleaning liquid enters the clean water tank 310 in the roller brush 210 through the flow channel 221, and the first water injection valve core 322 is provided to control the opening and closing state of the second water injection port 3212, thereby opening the second water injection port 3212 to allow the cleaning base station 2 to replenish the clean water tank 310 with water, or closing the second water injection port 3212 after the water replenishment is completed. Therefore, the floor brush 10 provided in the embodiment of the present application is smaller in size and is more convenient to replenish water.

[0089] In a possible implementation, both sides of the handle 220 along the moving direction of the floor brush 10 are respectively connected to the clean water tank 310 and the floor brush body 100 , and the flow channel 221 extends along the moving direction of the floor brush 10 .

[0090] 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 moving direction of the floor brush 10. Since the clean water tank 310 is located in the roller brush 210, the clean water tank 310 is also located at the end of the moving direction of the floor brush 10. The first water injection unit 320 can be arranged in the middle of the floor brush body 100 along the moving direction of the floor brush 10 to facilitate docking with the lifting member 21 of the cleaning base station 2. In this way, the handle member 220 can extend along the moving direction of the floor brush 10, and a flow channel 221 extending along the moving direction of the floor brush 10 is arranged in the handle member 220. In this way, the cleaning liquid flowing out from the first water injection port 3211 can flow along the moving direction of the floor brush 10 and then enter the clean water tank 310.

[0091] Since 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 the cleaning work proceeds, if the clean water tank 310 rotates with the roller brush 210, the cleaning liquid will shake greatly in the clean water tank 310, thereby causing the floor brush 10 to be unstable in use. In addition, compared with only driving a single roller brush 210 to rotate, driving the roller brush 210 and the clean water tank 310 to rotate together consumes more power, thereby increasing the ineffective power consumption of the floor brush 10. Therefore, in a possible implementation, the clean water tank 310 is fixedly connected to the handle 220, the roller brush 210 is rotatably connected to the clean water tank 310, and the handle 220 is detachably connected to the floor brush body 100.

[0092] In the above arrangement, firstly, the clean water tank 310 can be fixedly connected to the handle 220, thereby preventing the clean water tank 310 from rotating with the roller brush 210, thereby improving the stability of the floor brush 10 and reducing the power consumption of the floor brush 10. Secondly, the roller brush 210 is rotatably connected to the clean water tank 310, so that the roller brush 210 can be rotatably connected to the handle 220 through the clean water tank 310, and then the roller brush 210 is rotatably set on the floor brush body 100. Thirdly, the roller brush 210 is detachably connected to the floor brush body 100, so that when necessary, the roller brush assembly 200 and the clean water tank 310 can be removed from the floor brush body 100 as a whole.

[0093] Reference Fig.11 and Fig.12 As shown, in a specific implementation, the clean water tank 310 includes a water tank body 311, a first connection part 312 and a second connection part 313, the first connection part 312 and the second connection part 313 are connected to both ends of the water tank body 311, the roller brush 210 is rotatably connected to the first connection part 312, the second connection part 313 is fixedly connected to the handle 220, and the water tank body 311 is connected to the flow channel 221.

[0094] In this way, the water tank body 311 can be used to store cleaning liquid, and when needed, the water tank body 311 can be replenished with water through the first water injection unit 320 and the inner 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, and the second connecting part 313 is connected to the handle piece 220, so that the clean water tank 310 is fixedly connected to the handle piece 220, and the clean water tank 310 is statically arranged relative to the floor brush body 100, thereby preventing the clean water tank 310 from rotating with the roller brush 210.

[0095] Reference Figure 8 and Fig.12As shown, in a possible implementation, the roller brush assembly 200 further includes a threaded fastener 230, the second connection portion 313 is located at one end of the water tank body 311 facing the handle 220, the second connection portion 313 has a threaded connection hole 3131 and a third water injection port 3132, the water tank body 311 has a water containing cavity 3111, and the third water injection port 3132 is connected between the water containing cavity 3111 and the flow channel 221. The handle 220 has a through hole 222, and the threaded fastener 230 passes through the through hole 222 to be threadedly connected with the threaded connection hole 3131.

[0096] With such a configuration, the second connection portion 313 can be fixedly connected to the handle member 220 through the threaded fastener 230, thereby making the clean water tank 310 fixedly connected to the handle member 220, thereby preventing the clean water tank 310 from rotating along with the roller brush 210 when the roller brush 210 rotates. After the second connection portion 313 is fixedly connected to the handle member 220, the water containing chamber 3111 of the water tank body 311 can be connected to the flow channel 221 through the third water injection port 3132, thereby making the cleaning liquid enter the water containing chamber 3111 through the second water injection port 3212, the first water injection port 3211, the flow channel 221 and the third water injection port 3132 in sequence, thereby replenishing the clean water tank 310 with water.

[0097] Reference Figures 11 to 13 As shown, in order to detect the liquid amount in the clean water tank 310, in some embodiments, the water supply component 300 also includes a detection unit 330, the detection unit 330 includes a floating member 331, a magnetic member 332 and a detection sensor 333, the magnetic member 332 is connected to the floating member 331, the floating member 331 is rotatably set in the clean water tank 310, the detection sensor 333 is set on the outer wall of the clean water tank 310, and the detection sensor 333 is set corresponding to the magnetic member 332.

[0098] It can be understood that the floating member 331 will swing with the change of the liquid level, and the detection sensor 333 can detect the change of the liquid level by detecting the relative position change of the magnetic member 332. In this way, when the amount of liquid in the clean water tank 310 is insufficient, the floating member 331 will drop as the liquid level drops, and the magnetic member 332 will follow the floating member 331 to move away from the detection sensor 333, and feedback the detection result to the controller to remind the user to replenish the clean water tank 310 with water in time.

[0099] Alternatively, when the cleaning base station 2 fills 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 follows the floating member 331 to move toward the direction close to the detection sensor 333, and feeds back the detection result to the controller to remind the user that the water filling is completed.

[0100] The controller may be disposed in one of the floor brush 10 , the device host 20 and the cleaning base station 2 .

[0101] In a possible implementation, the floor brush body 100 includes a side cover 110 , the handle 220 is detachably connected to the side cover 110 , the side cover 110 has a mounting groove 111 , and the first water injection unit 320 is disposed in the mounting groove 111 .

[0102] In this way, the first water injection unit 320 can be installed in the installation groove 111 to install the first water injection unit 320 to the floor brush body 100, and the handle 220 can be detachably connected to the side cover 110 to make the handle 220 detachably connected to the floor brush body 100.

[0103] Reference Figure 5 , Figures 14 to 16 As shown, in some embodiments, the water supply assembly 300 also includes a signal transmission unit 340, which is electrically connected to the detection sensor 333. The signal transmission unit 340 includes a metal contact 341 and a metal spring needle 342. One of the metal contact 341 and the metal spring needle 342 is connected to the side cover 110, and the other is connected to the handle 220. The metal contact 341 is electrically connected to the metal spring needle 342.

[0104] It can be understood that since the roller brush assembly 200 and the clean water tank 310 are detachably connected to the side cover 110, and the detection unit 330 is arranged on the clean water tank 310, the detection result of the detection unit 330 needs to be fed back to the controller in a more flexible manner. In the above-mentioned setting, when the roller comb assembly and the clean water tank 310 are removed from the side cover 110, the metal contact 341 and the metal spring pin 342 are separated, thereby disconnecting the electrical connection. When the roller comb assembly and the clean water tank 310 are installed to the side cover 110, the metal contact 341 and the metal spring pin 342 are in contact, thereby establishing an electrical connection, so that the detection structure of the detection sensor 333 is fed back to the controller through the signal transmission unit 340.

[0105] Exemplarily, the metal contact piece 341 is provided on the side cover 110, the metal spring pin 342 is provided on the handle 220, the metal spring pin 342 can be connected to the detection sensor 333 through a wire, and the metal contact piece 341 is electrically connected to the metal spring pin 342. Alternatively, the metal spring pin 342 is provided on the side cover 110, the metal contact piece 341 is provided on the handle 220, the metal contact piece 341 can be connected to the detection sensor 333 through a wire, and the metal spring pin 342 is electrically connected to the metal contact piece 341.

[0106] In addition, in order to improve the reliability of the signal transmission unit 340, three groups of metal contact pieces 341 and three metal spring pins 342 may be provided, and the metal contact pieces 341 and the metal spring pins 342 are provided in a one-to-one correspondence.

[0107] Reference Fig. 9 and Fig.10 As shown, in a possible implementation, the first water injection unit 320 also includes a first elastic member 323, and the two ends of the elastic force direction of the first elastic member 323 are respectively connected to the first water injection valve body 321 and the first water injection valve core 322 to drive the first water injection valve core 322 to move toward the second water injection port 3212.

[0108] In this way, after the clean water tank 310 is replenished with cleaning liquid, the floor brush 10 is detached from the cleaning base station 2, so that the lifting member 21 is detached from the abutment with the first water injection valve core 322, and the first elastic member 323 can drive the first water injection valve core 322 to move toward the second water injection port 3212, so that the first water injection valve core 322 closes the second water injection port 3212, or, the lifting member 21 is controlled to retract, so that the lifting member 21 is detached from the abutment with the first water injection valve core 322, and the first elastic member 323 can drive the first water injection valve core 322 to move toward the second water injection port 3212, so that the first water injection valve core 322 closes the second water injection port 3212.

[0109] Reference Fig.17 and Fig.18 As shown, in some embodiments, the water supply assembly 300 also includes a second water injection unit 350, the second water injection unit 350 includes a second water injection valve core 351 and a second elastic member 352, the second water injection valve core 351 can be movably arranged at one end of the flow channel 221 away from the clean water tank 310, and the two ends of the elastic force direction of the second elastic member 352 are respectively connected to the handle 220 and the second water injection valve core 351 to drive the second water injection valve core 351 to close the flow channel 221.

[0110] The side cover 110 is provided with a connecting head 112, and the handle 220 is inserted into the connecting head 112. The two ends of the connecting head 112 are respectively connected to the first water injection port 3211 and the flow channel 221. A push rod 1121 is provided in the connecting head 112, and the push rod 1121 abuts against the second water injection valve core 351 to drive the second water injection valve core 351 to open the flow channel 221.

[0111] In this way, when disassembling the roller brush assembly 200, the elastic force of the second elastic member 352 can drive the second water injection valve to move toward the connecting head 112, so that the second water injection valve core 351 closes the flow channel 221, and then disconnects the flow channel 221 and the first water injection port 3211, thereby avoiding leakage of cleaning liquid in the clean water tank 310 and the flow channel 221.

[0112] When installing the roller brush assembly 200, the handle 220 can be plugged into the connecting head 112, so that the top rod 1121 abuts against the second water injection valve core 351, thereby driving the second water injection valve core 351 to move away from the connecting head 112, and then the second water injection valve core 351 opens the flow channel 221, so that the clean water tank 310, the flow channel 221 and the first water injection port 3211 are connected in sequence.

[0113] In a possible implementation, the moving direction of the first water injection valve core 322 points to the bottom surface of the floor brush body 100 , and the moving direction of the second water injection valve core 351 is consistent with the disassembly and assembly direction of the roller brush assembly 200 .

[0114] This arrangement allows the user to place the floor brush 10 on the cleaning base station 2 in a vertical direction or in a direction at a certain angle to the vertical direction, so that the lifting member 21 of the cleaning base station 2 can abut against the first water injection valve core 322 more accurately, thereby driving the first water injection valve core 322 to move away from the second water injection port 3212, so as to prevent the user from having to perform repeated operations to dock the floor brush 10 with the cleaning base station 2. And when the user installs the roller brush assembly 200 and the clean water tank 310 as a whole to the side cover 110, the ejector pin of the side cover 110 can abut against the second water injection valve core 351 more accurately, thereby opening the flow channel 221.

[0115] Exemplarily, the moving direction of the first water injection valve core 322 may be perpendicular to the bottom surface of the floor brush 10 , and the moving direction of the second water injection valve core 351 may be consistent with the axial direction of the roller brush 210 .

[0116] In a possible implementation, there are two roller brushes 210 , and the two roller brushes 210 are arranged at intervals along the moving direction of the floor brush 10 . A clean water tank 310 is provided in at least one roller brush 210 .

[0117] It should be noted that when the floor brush 10 is provided with two roller brushes 210 at intervals along its direction of travel, one roller brush 210 can be used for dry suction and the other roller brush 210 can be used for wet mopping, or both roller brushes 210 can be used for wet mopping. Such a combination can improve the cleaning effect and cleaning efficiency of the floor brush 10. In the above-mentioned setting method, the clean water tank 310 can be provided in one of the roller brushes 210, or both roller brushes 210 can be provided with the clean water tank 310, thereby increasing the cleaning liquid capacity of the floor brush 10 and thereby improving the endurance of the floor brush 10 when wet mopping.

[0118] In some embodiments, the clean water tank 310 and the roller brush 210 are disposed in a one-to-one correspondence, and the detection unit 330 is disposed in at least one of the two clean water tanks 310 .

[0119] In this way, the clean water tank 310 is disposed in each of the two roller brushes 210 , thereby increasing the cleaning liquid capacity of the floor brush 10 and thus improving the endurance of the floor brush 10 during wet mopping. At the same time, the clean water tank 310 does not increase the volume of the floor brush 10 .

[0120] It should be noted that the detection unit 330 can be provided in one of the two clean water tanks 310, and the two clean water tanks 310 can be connected to each other, and then the liquid volume of one of the clean water tanks 310 is detected by one detection unit 330 to detect whether the two clean water tanks 310 have completed water replenishment at the same time, thereby saving the cost of the floor brush 10. Alternatively, both clean water tanks 310 can be provided with a detection unit 330, and then the liquid volume of the corresponding clean water tank 310 is detected by the detection unit 330, so as to issue a reminder when the liquid volume of the clean water tank 310 is insufficient and when the water replenishment is completed.

[0121] In a possible implementation, the two clean water tanks 310 are connected to each other, the first water injection unit 320 is connected to one of the two clean water tanks 310 , and the detection unit 330 is disposed at the other of the two clean water tanks 310 .

[0122] That is to say, the two clean water tanks 310 may include a first clean water tank 310 and a second clean water tank 310, the first water injection unit 320 is connected to the first clean water tank 310, and the detection unit 330 can be set in the second clean water tank 310. When the floor brush 10 is docked with the cleaning base station 2, the cleaning base station 2 first replenishes water for the first clean water tank 310, and then replenishes water for the second clean water tank 310. When the detection unit 330 detects that the liquid level in the second clean water tank 310 is higher, it indicates that the first clean water tank 310 and the second clean water tank 310 have both been replenished.

[0123] Reference Fig.19 As shown, in a possible implementation, the water supply assembly 300 also includes a diverter 360, the diverter 360 has a confluence port 361 and two diverter ports 362, the confluence port 361 is connected to the first water inlet 3211, the diverter ports 362 are connected to the clean water tank 310 one-to-one, and the detection unit 330 is arranged one-to-one with the clean water tank 310.

[0124] Such an arrangement facilitates monitoring of the liquid levels of the two clean water tanks 310 , so as to issue a reminder when the liquid level of each clean water tank 310 is insufficient, and to issue a reminder when each clean water tank 310 is fully replenished.

[0125] It should be noted that the diameters of the two diversion ports 362 may be the same, so that the cleaning liquid entering the diversion member 360 may be evenly distributed to the two clean water tanks 310 .

[0126] 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 it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
