Description

Technical Field

[0001] The present application relates to the technical field of environmental cleaning appliances, and in particular to a floor brush and a cleaning device. 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 force 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 and then perform deep cleaning on the floor. 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. However, how to spray water on the roller brush through 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 and cleaning equipment to solve the deficiencies in the related art.

[0005] In the first aspect, the present application provides a floor brush, which includes a floor brush body, a roller brush assembly and a water spray assembly, the roller brush assembly includes a roller brush, the water spray assembly is connected to the floor brush body, the water spray assembly includes a clean water tank, a driving pump and a water spray member, the roller brush is rotatably arranged on the floor brush body, the clean water tank is located in the roller brush, the driving pump is connected between the clean water tank and the water spray member, and is constructed to drive the cleaning liquid in the clean water tank into the water spray member, the water spray member is arranged adjacent to the roller brush, and the water spray member has a water spray port facing the roller brush.

[0006] The floor brush provided by the present application is provided with a floor brush body for installing a roller brush assembly and a water spray assembly, a roller brush for rolling contact with the surface to be cleaned to clean the surface to be cleaned, a clean water tank for storing cleaning liquid, and the clean water tank 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 a driving pump is provided to provide power for the cleaning liquid to drive the cleaning liquid in the clean water tank to flow to the water spray component, and a water spray port is provided to spray the cleaning liquid on the outer surface of the roller brush to wet the roller brush, and then the wet roller brush is used to perform deep cleaning on the surface to be cleaned, thereby improving the cleaning effect of the floor brush. Therefore, the floor brush provided by the present application is small in size and has a good cleaning effect.

[0007] In a possible implementation, the roller brush assembly further includes a handle member, the handle member is connected to the floor brush body, the roller brush is rotatably connected to the handle member, the handle member has a flow channel, and the flow channel is connected between the clean water tank and the drive pump.

[0008] In this way, the roller brush can be rotatably connected to the handle piece, and then the roller brush can be installed on the floor brush body through the handle piece, so that the roller brush can be rotatably set relative to the floor brush body, and the clean water tank and the drive pump are connected through the flow channel of the handle piece, and then the drive pump is connected to the water spray part, so that the cleaning liquid in the water tank flows through the flow channel, the drive pump and the water spray part in sequence, and finally sprayed to the roller brush through the water spray port, thereby forming a water supply channel for the roller brush.

[0009] In a possible implementation manner, the flow channel extends along the travel direction of the floor brush.

[0010] In this way, the cleaning liquid in the clean water tank can flow along the moving direction of the floor brush, then enter the driving pump, and then enter the water spraying member.

[0011] In a possible implementation, the number of the flow channels is at least two, and the at least two flow channels are arranged side by side along the radial direction of the roller brush.

[0012] This is conducive to the cleaning liquid in the clean water tank entering the water spraying member in large quantities, thereby facilitating the water spraying member to spray more cleaning liquid onto the roller brush, thereby improving the cleaning efficiency of the roller brush.

[0013] 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.

[0014] In this way, the clean water tank can be integrated into the roller brush assembly to prevent the clean water tank from rotating with the roller brush, thereby improving the operating stability of the floor brush and reducing the power consumption of the floor brush, and making it easy to remove the clean water tank and roller brush assembly from the floor brush body when needed.

[0015] In one possible implementation, the handle also includes a first joint, which is connected to the end of the flow channel away from the clean water tank, and the extension direction of the first joint is consistent with the axial direction of the roller brush. The floor brush body has a second joint, the first joint is plugged into the second joint, and the second joint is connected to the drive pump.

[0016] In this way, the first connector and the second connector can be plugged together to establish a connection between the flow channel and the drive pump, thereby allowing the cleaning liquid to flow between the clean water tank, the flow channel, the drive pump and the water spraying member. When disassembling the roller brush assembly, the first connector and the second connector can be disconnected to disconnect the flow channel and the drive pump.

[0017] In a possible implementation, the roller brush assembly further includes a seal, which abuts between the first joint and the second joint to seal a gap between the first joint and the second joint.

[0018] In this way, after the first joint and the second joint are plugged in, the sealing member can effectively seal the gap between the first joint and the second joint, thereby preventing the cleaning liquid from leaking through the gap between the first joint and the second joint.

[0019] In a possible implementation, the roller brush assembly further includes a valve unit, the valve unit includes a valve core and an elastic member, the valve core is movably disposed in the first joint, the elastic member is sleeved on the valve core, and both ends of the elastic member in the elastic force direction are connected to the valve core and the handle member;

[0020] A push rod is arranged in the second joint, and the push rod abuts against the valve core to drive the valve core to open the first joint.

[0021] In this way, when the first connector is plugged into the second connector, the push rod abuts against the valve core, thereby driving the valve core to move away from the second connector, thereby opening the first connector, thereby enabling automatic connection between the clean water tank, the flow channel, the drive pump and the water spraying part; when the first connector is disconnected from the second connector, the push rod disengages from the valve core, and the elastic part drives the valve core to move toward the second connector, thereby blocking the first connector, thereby preventing leakage of the cleaning liquid.

[0022] In a possible implementation, the roller brush assembly also includes a threaded fastener, 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 second connecting part is located at one end of the water tank body facing the handle piece, the roller brush is rotatably connected to the first connecting part, the second connecting part has a threaded connection hole, the handle piece has a through hole, the through hole and the threaded connection hole both extend along the axial direction of the roller brush, and the threaded connecting part passes through the through hole and is threadedly connected to the threaded connection hole.

[0023] In this way, the water tank body can be used to store cleaning liquid, and the clean water tank can be rotatably connected to the roller brush by setting a first connecting part, so that the roller brush is rotatably connected to the clean water tank, and the second connecting part can be fixedly connected to the handle piece by a threaded fastener, 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.

[0024] In a possible implementation, the second connecting portion has a water flow channel, the water tank body defines a water containing chamber, and the water flow channel is connected between the water containing chamber and the flow channel.

[0025] In this way, the water holding chamber can be used to hold cleaning liquid. When the floor brush is working, when it is necessary to provide cleaning liquid to the water spraying element through the clean water tank, the cleaning liquid in the water holding chamber can enter the flow channel through the water flow channel. Alternatively, when it is necessary to replenish the water holding chamber with cleaning liquid, the cleaning liquid can be injected into the water holding chamber through the water flow channel.

[0026] In a possible implementation, two roller brushes are spaced apart along the travel direction of the floor brush, and at least one roller brush is provided with a clean water tank.

[0027] 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, thereby improving the cleaning effect and cleaning efficiency of the floor brush. A clean water tank can be arranged in one of the roller brushes, or both roller brushes can be arranged in the clean water tank, thereby increasing the cleaning liquid capacity of the floor brush, thereby improving the endurance of the floor brush when wet mopping.

[0028] In a possible implementation, the water spray assembly also includes a diverter member, which is arranged one-to-one with the roller brush. The diverter member has a confluence port and two diverter ports that are interconnected. The confluence port is connected to the drive pump, and the two diverter ports are connected one-to-one with the two water spray members.

[0029] In this way, by providing a flow divider between the driving pump and the two water spraying parts, the two water spraying parts can share one driving pump, thereby simplifying the structure of the floor brush and reducing the cost of the floor brush.

[0030] In a possible implementation, the clean water tank and the roller brush are arranged in a one-to-one correspondence, the two clean water tanks are connected to each other, and the driving pump is connected to at least one of the two clean water tanks.

[0031] In this way, the driving pump can suck the cleaning liquid in any clean water tank, and then drive the cleaning liquid into the water spraying member.

[0032] In a possible implementation, the number of the water spray ports is at least two, and the at least two water spray ports are spaced apart along the axial direction of the roller brush.

[0033] In this way, the water spraying member can evenly spray cleaning liquid onto the surface of the roller brush, thereby improving the cleaning effect of the floor brush.

[0056] The terms "first", "second", "third" (if any) in the specification and claims of this 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 application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0057] 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.

[0058] 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 force 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 and then perform deep cleaning on the floor. 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. However, how to spray water on the roller brush through the clean water tank is a problem that needs to be solved urgently.

[0059] In view of the above problems, an embodiment of the present application provides a floor brush, 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 the cleaning liquid in the clean water tank can be driven by a driving pump to a water spray part, and then the cleaning liquid is sprayed onto the outer surface of the roller brush through the water spray part, so that the roller brush can wet-mop the surface to be cleaned.

[0060] The specific implementation of the floor brush and cleaning device provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0061] Reference Figure 1 As shown, the cleaning device provided in the embodiment of the present application includes a floor brush 10 and a device host 20 , and the floor brush 10 is connected to the device host 20 .

[0062] It can be understood that the floor brush 10 is 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 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.

[0063] Reference Figures 2 to 4As shown, specifically, 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 spray assembly 300, the roller brush assembly 200 includes a roller brush 210, the water spray assembly 300 is connected to the floor brush body 100, the water spray assembly 300 includes a clean water tank 310, a driving pump 320 and a water spray member 330, the roller brush 210 is rotatably arranged on the floor brush body 100, the clean water tank 310 is located in the roller brush 210, the driving pump 320 is connected between the clean water tank 310 and the water spray member 330, and is constructed to drive the cleaning liquid in the clean water tank 310 into the water spray member 330, the water spray member 330 is arranged adjacent to the roller brush 210, and the water spray member 330 has a water spray port 331 facing the roller brush 210.

[0064] In the present application, the floor brush body 100 is used to install a roller brush assembly 200 and a water spray assembly 300. The roller brush assembly 200 is used to clean the surface to be cleaned, and the water spray assembly 300 is used to spray cleaning liquid onto the roller brush assembly 200. Specifically, the roller brush assembly 200 may include a roller brush 210. When the roller brush 210 rolls, the outer surface of the roller brush 210 is used to contact the surface to be cleaned, thereby scrubbing the surface to be cleaned, or assisting in sucking away dirt on the surface to be cleaned. The water spray assembly 300 includes a clean water tank 310, a drive pump 320 and a water spray member 330. The clean water tank 310 is used to store cleaning liquid, and the drive pump 320 is used to provide a driving force for the cleaning liquid, thereby driving the cleaning liquid in the clean water tank 310 into the water spray member 330. The water spray member 330 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 to self-clean the roller brush 210 with the cleaning liquid.

[0065] Compared with the related art, in which the clean water tank 310 is arranged on the floor brush body 100 or on the device host 20, in the floor brush 10 of the embodiment of the present application, the clean water tank 310 is arranged in the roller brush 210. In this way, the clean water tank 310 and the roller brush 210 share part of the space, and the overall structure of the floor brush 10 can be made more compact, thereby effectively reducing the volume of the floor brush 10.

[0066] 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 spray assembly 300, the roller brush assembly 200 includes a roller brush 210, the water spray assembly 300 includes a clean water tank 310, a drive pump 320 and a water spray component 330, and the water spray component 330 includes a water spray port 331. The floor brush body 100 is provided for mounting the roller brush assembly 200 and the water spray assembly 300, the roller brush 210 is provided for rolling contact with the surface to be cleaned to clean the surface to be cleaned, the clean water tank 310 is provided for storing the cleaning liquid, the clean water tank 310 is integrated into 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, the driving pump 320 is provided for providing power for the cleaning liquid to drive the cleaning liquid in the clean water tank 310 to flow to the water spraying member 330, and the water spraying port 331 is provided for spraying the cleaning liquid onto the outer surface of the roller brush 210 to wet the roller brush 210, and then the wet roller brush 210 is used to deeply clean the surface to be cleaned, thereby improving the cleaning effect of the floor brush 10. Therefore, the floor brush 10 provided in the embodiment of the present application is small in volume and has a good cleaning effect.

[0067] Reference Figures 3 to 7 As shown, in a possible implementation, the roller brush assembly 200 also includes a handle 220, which is connected to the floor brush body 100, and the roller brush 210 is rotatably connected to the handle 220. The handle 220 has a flow channel 221, and the flow channel 221 is connected between the clean water tank 310 and the drive pump 320.

[0068] In this way, the roller brush 210 can be rotatably connected to the handle piece 220, and then the roller brush 210 can be installed on the floor brush body 100 through the handle piece 220, so that the roller brush 210 is rotatably set relative to the floor brush body 100, and the clean water tank 310 and the driving pump 320 are connected through the flow channel 221 of the handle piece 220, and then the driving pump 320 is connected to the water spraying part 330, so that the cleaning liquid in the water tank flows through the flow channel 221, the driving pump 320 and the water spraying part 330 in sequence, and finally sprayed to the roller brush 210 through the water spraying port 331, thereby forming a water supply channel for the roller brush 210.

[0069] The handle member 220 may include a first handle member 220 a and a second handle member 220 b , and the first handle member 220 a and the second handle member 220 b are connected to define a flow channel 221 .

[0070] In some embodiments, the flow channel 221 extends along the travel direction of the floor brush 10. It should be noted that the roller brush 210 can be arranged at the front end or rear end of the floor brush body 100 along the travel direction of the floor brush 10, and correspondingly, the clean water tank 310 is also located at the end of the floor brush 10 in the travel direction, and the driving pump 320 can be arranged in the middle of the floor brush body 100 in the travel direction of the floor brush 10. Since the handle 220 is provided with a flow channel 221 extending along the travel direction of the floor brush 10, the cleaning liquid in the clean water tank 310 can flow along the travel direction of the floor brush 10, and then enter the driving pump 320, and then enter the water spraying member 330.

[0071] In a possible implementation, the number of the flow channels 221 is at least two, and at least two flow channels 221 are arranged side by side along the radial direction of the roller brush 210 .

[0072] It is understandable that when the number of flow channels 221 is large, it is beneficial for the cleaning liquid in the clean water tank 310 to enter the water spraying member 330 in large quantities, thereby facilitating the water spraying member 330 to spray more cleaning liquid onto the roller brush 210, thereby improving the cleaning efficiency of the roller brush 210.

[0073] In some embodiments, 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 .

[0074] 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 progresses, in order to improve the stability of the floor brush 10 and reduce the power consumption of the floor brush 10, the clean water tank 310 can be fixedly connected to the handle 220 to prevent the clean water tank 310 from rotating with the roller brush 210.

[0075] If the clean water tank 310 rotates with the roller brush 210, the cleaning liquid will sway greatly in the clean water tank 310, thereby causing the floor brush 10 to be unstable in use. In addition, compared with driving only the single roller brush 210 to rotate, driving the roller brush 210 and the clean water tank 310 to rotate together consumes more energy, thereby increasing the ineffective power consumption of the floor brush 10.

[0076] It should be noted that since the roller brush 210 needs to be removed from the floor brush body 100 for cleaning after being used for a period of time, the roller brush 210 can be detachably connected to the floor brush body 100. In the above-mentioned setting, the roller brush 210 is rotatably connected to the clean water tank 310, and the clean water tank 310 is fixedly connected to the handle 220, and the handle 220 is detachably connected to the floor brush body 100. In this way, it is convenient to remove the roller brush assembly 200 and the clean water tank 310 from the floor brush body 100 as a whole when needed.

[0077] Reference Figure 8 and Fig. 9 As shown, in a possible implementation, the handle 220 also includes a first connector 222, which is connected to the end of the flow channel 221 away from the clean water tank 310, and the extension direction of the first connector 222 is consistent with the axial direction of the roller brush 210. The floor brush body 100 has a second connector 110, and the first connector 222 is plugged into the second connector 110, and the second connector 110 is connected to the drive pump 320.

[0078] Because the flow channel 221 needs to be disconnected from the drive pump 320 when the roller brush assembly 200 is disassembled, and the flow channel 221 needs to be connected to the drive pump 320 when the roller brush assembly 200 is installed, the first joint 222 can be provided on the handle 220, and the second joint 110 can be provided on the floor brush body 100, and then the first joint 222 and the second joint 110 can be plugged in to establish a connection between the flow channel 221 and the drive pump 320, so that the cleaning liquid can flow between the clean water tank 310, the flow channel 221, the drive pump 320 and the water spraying member 330. When the roller brush assembly 200 is disassembled, the flow channel 221 and the drive pump 320 can be disconnected by disengaging the first joint 222 and the second joint 110.

[0079] Reference Figure 5 and Figure 8 As shown, in some embodiments, the roller brush assembly 200 further includes a seal 240 , which abuts between the first joint 222 and the second joint 110 to seal the gap between the first joint 222 and the second joint 110 .

[0080] With such configuration, after the first joint 222 and the second joint 110 are plugged in, the seal 240 can effectively seal the gap between the first joint 222 and the second joint 110 , thereby preventing the cleaning liquid from leaking through the gap between the first joint 222 and the second joint 110 .

[0081] Reference Figure 8 and Fig. 9 As shown, in a possible implementation, the roller brush assembly 200 further includes a valve unit 250, the valve unit 250 includes a valve core 251 and an elastic member 252, the valve core 251 is movably disposed in the first joint 222, the elastic member 252 is sleeved on the valve core 251, and both ends of the elastic force direction of the elastic member 252 are connected to the valve core 251 and the handle 220. A push rod 111 is disposed in the second joint 110, and the push rod 111 abuts against the valve core 251 to drive the valve core 251 to open the first joint 222.

[0082] In the above-mentioned setting, when the first joint 222 is plugged into the second joint 110, the push rod 111 abuts against the valve core 251, thereby driving the valve core 251 to move away from the second joint 110, thereby opening the first joint 222, thereby connecting the flow channel 221 and the drive pump 320. In this way, when the roller brush assembly 200 is installed to the floor brush body 100, the clean water tank 310, the flow channel 221, the drive pump 320 and the water spraying member 330 can be automatically connected. When the first joint 222 is disengaged from the second joint 110, the push rod 111 is disengaged from the abutment with the valve core 251, and the elastic member 252 drives the valve core 251 to move toward the second joint 110, thereby blocking the first joint 222, thereby disconnecting the connection between the flow channel 221 and the drive pump 320. In this way, when the roller brush assembly 200 is removed from the floor brush body 100, the flow channel 221 can be automatically blocked, thereby preventing leakage of the cleaning liquid.

[0083] Reference Figure 6 As shown, in order to fix the clean water tank 310 to the handle member 220, in a possible implementation, the roller brush assembly 200 also includes a threaded fastener 230, the clean water tank 310 includes a water tank body 311, a first connecting portion 312 and a second connecting portion 313, the first connecting portion 312 and the second connecting portion 313 are connected to both ends of the water tank body 311, the second connecting portion 313 is located at one end of the water tank body 311 facing the handle member 220, the roller brush 210 is rotatably connected to the first connecting portion 312, the second connecting portion 313 has a threaded connection hole, the handle member 220 has a through hole 223, the through hole 223 and the threaded connection hole both extend along the axial direction of the roller brush 210, and the threaded fastener 230 passes through the through hole 223 and is threadedly connected to the threaded connection hole.

[0084] In this way, the water tank body 311 can be used to store cleaning liquid, and the clean water tank 310 can be rotatably connected to the roller brush 210 by setting a first connecting part 312, so that the roller brush 210 is rotatably connected to the clean water tank 310, and the second connecting part 313 can be fixedly connected to the handle piece 220 through a threaded fastener 230, 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.

[0085] In some embodiments, the second connection portion 313 has a water flow channel, the water tank body 311 defines a water containing cavity, and the water flow channel communicates between the water containing cavity and the flow channel 221 .

[0086] With such a configuration, the water holding chamber can be used to hold cleaning liquid. When the floor brush 10 is working, when it is necessary to provide cleaning liquid to the water spraying member 330 through the clean water tank 310, the cleaning liquid in the water holding chamber can enter the flow channel 221 through the water flow channel, or, when it is necessary to replenish the water holding chamber with cleaning liquid, the cleaning liquid can be injected into the water holding chamber through the water flow channel.

[0087] In some embodiments, two roller brushes 210 are spaced apart along the moving direction of the floor brush 10 , and at least one roller brush 210 is provided with a clean water tank 310 .

[0088] It should be understood that when the floor brush 10 is provided with two roller brushes 210 at intervals along its own moving direction, 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 are used for wet mopping, which is not limited in the present embodiment. The clean water tank 310 can be provided in one of the roller brushes 210, or the clean water tank 310 can be provided in both roller brushes 210, thereby increasing the cleaning liquid capacity of the floor brush 10, and thereby increasing the endurance of the floor brush 10 when wet mopping.

[0089] Reference Fig.10 As shown, in a possible implementation, the water spray assembly 300 also includes a diverter 340, the water spray member 330 is arranged one-to-one with the roller brush 210, the diverter 340 has a confluence port 341 and two diverter ports 342 that are interconnected, the confluence port 341 is connected to the drive pump 320, and the two diverter ports 342 are connected one-to-one with the two water spray members 330.

[0090] That is to say, the driving pump 320 is connected to the clean water tank 310, the confluence port 341 is connected to the driving pump 320, and the diversion port 342 is connected to the water spraying member 330. In this way, by setting the diversion member 340 between the driving pump 320 and the two water spraying members 330, the two water spraying members 330 can share one driving pump 320, thereby simplifying the structure of the floor brush 10 and reducing the cost of the floor brush 10.

[0091] The flow rates of the two diversion ports 342 may be consistent, so that the cleaning liquid can enter the two water spraying members 330 evenly, and further the cleaning liquid can be sprayed evenly onto the two rolling brushes 210 .

[0092] It should be noted that, in the above-mentioned configuration, the floor brush 10 may be provided with only one clean water tank 310 , or the floor brush 10 may be provided with two clean water tanks 310 .

[0093] In a possible implementation, the clean water tank 310 and the roller brush 210 are disposed in a one-to-one correspondence, the two clean water tanks 310 are connected to each other, and the driving pump 320 is connected to at least one of the two clean water tanks 310 .

[0094] That is to say, the driving pump 320 can be connected to one or both of the two clean water tanks 310 , and the two clean water tanks 310 are connected to each other, so that the driving pump 320 can suck the cleaning liquid in any one of the clean water tanks 310 , and then drive the cleaning liquid into the water spraying member 330 .

[0095] In some embodiments, there are at least two water spray ports 331, and at least two water spray ports 331 are spaced apart along the axial direction of the roller brush 210. In this way, the water spray member 330 can evenly spray cleaning liquid onto the surface of the roller brush 210, thereby improving the cleaning effect of the floor brush 10.
