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 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 a 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 to the two roller brushes 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 a first aspect, the present application provides a floor brush, comprising a floor brush body, a roller brush assembly and a water spray assembly, wherein the roller brush assembly comprises two roller brush units, the roller brush unit comprises a roller brush, the two roller brushes are arranged at intervals along the travel direction of the floor brush, and the roller brush is rotatably arranged on the floor brush body;

[0006] The water spray assembly is connected to the floor brush body, and the water spray assembly includes a clean water tank, a driving pump, a flow divider and two water spray members. The clean water tank is arranged in at least one roller brush, and the water spray members are arranged one by one with the roller brushes.

[0007] The flow dividing member comprises an inlet pipe, a first outlet pipe and a second outlet pipe which are interconnected. The driving pump is connected between the clean water tank and the inlet pipe. The first outlet pipe is connected to one water spraying member, and the second outlet pipe is connected to another water spraying member.

[0008] The floor brush provided in the embodiment of 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 spray to the roller brush through the water spray part to wet the roller brush, and a water inlet pipe is provided to connect the driving pump, and a first water outlet pipe and a second water outlet pipe are provided to connect the two water spray parts respectively, so that one driving pump is used to drive the cleaning liquid to enter the two water spray parts at the same time, thereby simplifying the structure of the floor brush and reducing the cost, thereby improving the cleaning effect of the floor brush. Therefore, the floor brush provided in the present application is small in size and has a good cleaning effect.

[0009] In a possible implementation, the roller brush unit further includes a handle, the handle is connected to the floor brush body, the roller brush is connected to the handle, the handle has a flow channel, and the flow channel is connected between the clean water tank and the drive pump.

[0010] In this way, the roller brush set on the floor brush body can be rotated by the handle piece. At the same time, a flow channel is set on the handle piece, and then the clean water tank and the driving pump are connected through the flow channel, and then the driving pump is connected to the water spraying part, so that the cleaning liquid in the water tank flows along the flow channel, the driving pump, and the diverter part in sequence, and then is divided into two paths by the diverter part and flows to the two water spraying parts, and finally is sprayed to the corresponding roller brush through the water spray port. The clean water tank, the flow channel, the driving pump, the diverter part and the water spraying part are connected in sequence, thereby forming a water supply channel for the roller brush.

[0011] In a possible implementation, the first water outlet pipe and the second water outlet pipe are coaxially connected, the water inlet pipe is located between the first water outlet pipe and the second water outlet pipe, and the axial direction of the water inlet pipe is perpendicular to the axial direction of the first water outlet pipe.

[0012] Thus, after the cleaning liquid in the clean water tank enters the water inlet pipe through the flow channel, the cleaning liquid is divided into two paths and flows in opposite directions, and then enters the first water outlet pipe and the second water outlet pipe respectively, and then flows to the two water spraying parts.

[0013] In a possible implementation, it also includes a fixed bracket, the fixed bracket is connected to the floor brush body, the drive pump is connected to the fixed bracket, the fixed bracket has a limiting area, and the diverter is located in the limiting area.

[0014] In this way, the drive pump can be installed to the floor brush body through a fixed bracket, so that the drive pump is fixedly connected relative to the floor brush body, and the diverter can be restricted in the limiting area of ​​the fixed bracket, thereby preventing the diverter from moving freely in the floor brush body.

[0015] In a possible implementation, the fixing bracket has a first limiting rib, a second limiting rib and a third limiting rib, and the first limiting rib includes a first limiting segment and a second limiting segment connected to each other;

[0016] The extension direction of the first limiting section and the extension direction of the second limiting rib are both consistent with the axial direction of the water inlet pipe, and the first limiting section and the second limiting rib are located on both sides of the water inlet pipe, the extension direction of the second limiting section is consistent with the axial direction of the first water outlet pipe, the extension direction of the third limiting rib is consistent with the axial direction of the second water outlet pipe, the second limiting section and the third limiting rib are located on both sides of the first water outlet pipe, and the first limiting rib, the second limiting rib and the third limiting rib jointly define a limiting area.

[0017] In this way, the first limiting section and the second limiting rib cooperate with each other to limit the radial displacement of the water inlet pipe, and the first limiting section and the third limiting rib cooperate with each other to limit the radial displacement of the first water outlet pipe and the second water outlet pipe. Since the water inlet pipe is located between the first water outlet pipe and the second water outlet pipe, when the radial displacement of the water inlet pipe is limited, the axial displacement of the first water outlet pipe and the second water outlet pipe is also limited. When the radial displacement of the first water outlet pipe and the second water outlet pipe is limited, the axial displacement of the water inlet pipe is also limited, thereby preventing the diverter from moving arbitrarily in the floor brush body.

[0018] In a possible implementation manner, the first water outlet pipe and the second water outlet pipe have different inner diameters.

[0019] In this way, by making the inner diameters of the first water outlet pipe and the second water outlet pipe different, the two water spraying members obtain different amounts of liquid, thereby improving the cleaning effect of the floor brush.

[0020] In a possible implementation, the two roller brushes include a first roller brush and a second roller brush, and the two water spraying members include a first water spraying member and a second water spraying member;

[0021] The first roller brush is located at the front end of the floor brush in the direction of travel, the second roller brush is located at the rear end of the floor brush in the direction of travel, the first water spraying member is arranged correspondingly to the first roller brush, and the second water spraying member is arranged correspondingly to the second roller brush;

[0022] The first water outlet pipe is connected to the first water spraying member, the second water outlet pipe is connected to the second water spraying member, and the inner diameter of the first water outlet pipe is greater than the inner diameter of the second water outlet pipe.

[0023] In this way, by making the inner diameter of the first water outlet pipe larger than the inner diameter of the second water outlet pipe, more liquid enters the first water spray part and less liquid enters the second water spray part, so that more cleaning liquid is sprayed toward the first roller brush, thereby providing the cleaning effect of the first roller brush, and less cleaning liquid is sprayed toward the second roller brush, thereby avoiding leaving more water stains on the surface to be cleaned.

[0024] In a possible implementation, the first water outlet pipe extends in a direction pointing toward the first roller brush, and the second water outlet pipe extends in a direction pointing toward the second roller brush.

[0025] This helps to shorten the distance between the first water outlet pipe and the first roller brush, and helps to shorten the distance between the second water outlet pipe and the second roller brush, thereby facilitating the cleaning liquid to quickly reach the first roller brush and the second roller brush.

[0026] In a possible implementation, the clean water tank includes a first clean water tank and a second clean water tank, the first clean water tank is located in the first roller brush, the second clean water tank is located in the second roller brush, and the first clean water tank and the second clean water tank are connected to each other.

[0027] Thus, two clean water tanks are provided on the floor brush to increase the cleaning liquid capacity of the floor brush, thereby increasing the endurance of the floor brush during wet mopping. When the floor brush is working, the driving pump is simultaneously connected to the first water spraying member and the second water spraying member through the diverter, so that cleaning liquid can be provided to the first water spraying member and the second water spraying member through any one of the first clean water tank and the second clean water tank.

[0028] In one possible implementation, the clean water tank includes a water tank body and a first connecting part that are interconnected, the water tank body has a water containing cavity, the first connecting part is located at one end of the water tank body facing the handle, the first connecting part has a water flow channel, and the water flow channel is connected between the flow channel and the water containing cavity.

[0029] In this way, the water holding chamber can be used to store cleaning liquid, and the water flow channel can be used to connect the flow channel and the water holding chamber, so that the cleaning liquid in the water holding chamber flows through the water flow channel, the flow channel, the driving pump, the diverter and the water spraying part in sequence, and is finally sprayed to the roller brush through the water spraying port, thereby wetting the roller brush.

[0030] In a possible implementation, the roller brush unit further includes a threaded connector, the handle member has a through hole, the first connecting portion has a threaded connection hole, and the threaded connector passes through the through hole and is threadedly connected to the threaded connection hole.

[0031] In this way, the first connecting part can be fixedly connected to the handle piece by a threaded connecting part, 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, thereby preventing the cleaning liquid in the clean water tank from shaking drastically and affecting the stability of the floor brush, and avoiding the clean water tank from rotating with the roller brush and increasing the power consumption of the floor brush.

[0032] In a possible implementation, the clean water tank also includes a second connection part, the first connection part and the second connection part are connected to two ends of the water tank body, the roller brush is rotatably connected to the second connection part, and the handle is detachably connected to the floor brush body.

[0033] In this way, the roller brush can be rotatably connected to the handle, and then the roller brush can be rotatably and detachably connected to the floor brush body.

[0034] In a possible implementation, the handle also includes a first joint, the first joint is connected to the end of the flow channel away from the clean water tank, the floor brush body has a second joint, the second joint is connected to the drive pump, and the first joint is connected to the second joint by plug connection.

[0035] In this way, when the roller brush unit is installed on the floor brush body, the first connector is plugged into and connected with the second connector, so that the clean water tank, the flow channel, the driving pump, the diverter and the water spraying part are connected in sequence, thereby facilitating the cleaning liquid in the clean water tank to enter the water spraying part along the flow channel, the driving pump and the diverter in sequence.

[0036] In a possible implementation, the roller brush unit further includes a valve core and an elastic member, the valve core is movably disposed in the first joint, the elastic member is connected between the valve core and the handle, and the elastic force direction of the elastic member points to the valve core to drive the valve core to close the first joint;

[0037] 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.

[0038] Thus, when the roller brush unit is installed on the floor brush body, the flow channel is automatically connected to the driving pump. When the roller brush assembly is removed from the floor brush body, the valve core can automatically close the first joint, thereby preventing the cleaning liquid in the flow channel and the clean water tank from leaking.

[0039] 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.

[0060] 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.

[0062] 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 and then perform a 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 to the two roller brushes through the clean water tank is a problem that needs to be solved urgently.

[0063] In view of the above problems, an embodiment of the present application provides a floor brush and a cleaning device, 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 diverter, and then distributed to two water spray parts through the diverter, and then the cleaning liquid is sprayed onto the outer surface of the corresponding roller brush through the water spray parts, thereby improving the cleaning effect of the floor brush.

[0064] 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.

[0065] Reference Figure 1 As shown, the present application provides a cleaning device, including a floor brush 10 and a device host 20, and the floor brush 10 is connected to the device host 20. It should be understood that the floor brush 10 can be used to contact with the surface to be cleaned, and then clean the surface to be cleaned, and the device host 20 can provide suction force and power for the floor brush 10, so that when the cleaning device moves relative to the surface to be cleaned, the floor brush 10 can perform dry suction and wet mopping operations on the surface to be cleaned.

[0066] Reference Figures 2 to 6 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 spray assembly 300, the roller brush assembly 200 includes two roller brush units 210, the roller brush unit 210 includes a roller brush 211, the two roller brushes 211 are arranged at intervals along the moving direction of the floor brush 10, and the roller brush 211 is rotatably arranged on the floor brush body 100.

[0067] The water spray assembly 300 is connected to the floor brush body 100, and the water spray assembly 300 includes a clean water tank 310, a driving pump 320, a diverter 330 and two water spray members 340. The clean water tank 310 is arranged in at least one roller brush 211, and the water spray members 340 are arranged one by one with the roller brush 211, and the water spray members 340 have a water spray port facing the roller brush 211.

[0068] The flow divider 330 includes an inlet pipe 331, a first outlet pipe 332, and a second outlet pipe 333 that are interconnected. The driving pump 320 is connected between the clean water tank 310 and the inlet pipe 331. The first outlet pipe 332 is connected to one water spraying member 340, and the second outlet pipe 333 is connected to another water spraying member 340. In the present application, the floor brush body 100 is used to install the roller brush assembly 200 and the water spraying assembly 300. The roller brush assembly 200 is used to contact with the surface to be cleaned to clean the surface to be cleaned. The water spraying assembly 300 is used to spray cleaning liquid to the roller brush assembly 200 so that the roller brush assembly 200 performs a wet mopping operation on the surface to be cleaned, or spray cleaning liquid to the roller brush assembly 200 for self-cleaning.

[0069] Specifically, the roller brush assembly 200 may include two roller brush units 210, each roller brush unit 210 has a roller brush 211, wherein both roller brushes 211 may be used for dry suction, or one roller brush 211 may be used for dry suction and the other roller brush 211 may be used for wet mopping, or both roller brushes 211 may be used for wet mopping, thereby improving the cleaning efficiency and cleaning effect of the floor brush 10, and the user may select different working modes according to the cleaning needs, and the floor brush 10 is more convenient to use. When the roller brush 211 rolls on the surface to be cleaned, the outer surface of the roller brush 211 contacts the surface to be cleaned, thereby scrubbing the surface to be cleaned, or the auxiliary device host 20 sucks away dirt from the surface to be cleaned.

[0070] The water spray assembly 300 includes a clean water tank 310, a driving pump 320, a flow divider 330 and a water spray member 340, wherein there are two water spray members 340, so that each roller brush 211 is provided with a corresponding water spray member 340. The clean water tank 310 is arranged in the roller brush 211 for storing cleaning liquid. Compared with the related art, in which the clean water tank 310 is arranged in the floor brush body 100 or in the device host 20, the clean water tank 310 and the roller brush 211 of the present application 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. The driving pump 320 is used to provide driving force for the cleaning liquid, thereby driving the cleaning liquid in the clean water tank 310 to enter the diverter 330. Because the diverter 330 has an inlet pipe 331, a first outlet pipe 332 and a second outlet pipe 333, the cleaning liquid can be divided into two by the diverter 330. After being divided into two paths, they enter the two water spraying parts 340 respectively through the first outlet pipe 332 and the second outlet pipe 333. In this way, the cleaning liquid can be sprayed to the two roller combs at the same time through a driving pump 320 to simplify the structure of the water spraying assembly 300 and reduce the cost of the floor brush 10. The water spraying port of the water spraying part 340 is used to spray cleaning liquid to the roller brush 211 to wet the outer surface of the roller brush 211, thereby facilitating the roller brush 211 to deeply clean the surface to be cleaned, or the roller brush 211 can be self-cleaned by the cleaning liquid.

[0071] The inner diameters of the first water outlet pipe 332 and the second water outlet pipe 333 may be the same, so that the two water spraying members 340 obtain the same amount of liquid.

[0072] Alternatively, the inner diameters of the first water outlet pipe 332 and the second water outlet pipe 333 may be different. When the two floor brushes 10 have different requirements for the amount of cleaning liquid, if the inner diameters of the first water outlet pipe 332 and the second water outlet pipe 333 are the same, the amount of liquid distributed to the two water spraying parts 340 is the same. Therefore, in some embodiments, the inner diameters of the first water outlet pipe 332 and the second water outlet pipe 333 may be different. For example, the inner diameter of the first water outlet pipe 332 may be larger than the inner diameter of the second water outlet pipe 333, or the inner diameter of the first water outlet pipe 332 may be smaller than the inner diameter of the second water outlet pipe 333. In this way, by adjusting the inner diameters of the first water outlet pipe 332 and the second water outlet pipe 333, the same driving pump 320 can drive different amounts of liquid to the two water spraying parts 340, thereby improving the cleaning effect of the floor brush 10.

[0073] 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 unit 210, the roller brush unit 210 includes a roller brush 211, the water spray assembly 300 includes a clean water tank 310, a drive pump 320, a diverter 330 and a water spray member 340, the diverter 330 includes a water inlet pipe 331, a first water outlet pipe 332 and a second water outlet pipe 333, and the water spray member 340 includes a water spray port. By setting a floor brush body 100 for mounting a roller brush assembly 200 and a water spray assembly 300, by setting a roller brush 211 for rolling contact with a surface to be cleaned so as to clean the surface to be cleaned, by setting a clean water tank 310 for storing cleaning liquid, by integrating the clean water tank 310 in the roller brush 211 so that the clean water tank 310 and the roller brush 211 share part of the space, thereby reducing the volume of the floor brush 10, by setting a driving pump 320 for providing power for the cleaning liquid so as to drive the cleaning liquid in the clean water tank 310 to be sprayed toward the roller brush 211 through the water spray member 340, and by setting a spray The water inlet is used to spray cleaning liquid onto the outer surface of the roller brush 211 to wet the roller brush 211. The water inlet pipe 331 is provided to connect the driving pump 320. The first water outlet pipe 332 and the second water outlet pipe 333 are provided to connect the two water spraying parts 340 respectively, so that one driving pump 320 is used to drive the cleaning liquid to enter the two water spraying parts 340 at the same time, thereby simplifying the structure of the floor brush 10 and reducing the cost. By making the inner diameters of the first water outlet pipe 332 and the second water outlet pipe 333 different, the two water spraying parts 340 obtain different amounts of liquid, 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 size and has a good cleaning effect.

At the same time, a flow channel 2121 is set in the handle part 212, and then the clean water tank 310 and the driving pump 320 are connected through the flow channel 2121, and then the driving pump 320 is connected to the water spraying part 340, so that the cleaning liquid in the water tank flows along the flow channel 2121, the driving pump 320, and the diverter part 330 in sequence, and then is divided into two paths by the diverter part 330 and flows to the two water spraying parts 340, and finally is sprayed to the corresponding roller brush 211 through the water spray port. In this way, the clean water tank 310, the flow channel 2121, the driving pump 320, the diverter part 330 and the water spraying part 340 are connected in sequence to form a water supply channel for the roller brush 211.

[0076] In some embodiments, the first water outlet pipe 332 and the second water outlet pipe 333 are coaxially connected, the water inlet pipe 331 is located between the first water outlet pipe 332 and the second water outlet pipe 333 , and the axial direction of the water inlet pipe 331 is perpendicular to the axial direction of the first water outlet pipe 332 .

[0077] That is to say, the diverter 330 is T-shaped. When the cleaning liquid in the clean water tank 310 enters the water inlet pipe 331 through the flow channel 2121, the cleaning liquid is divided into two paths and flows in opposite directions, and then enters the first water outlet pipe 332 and the second water outlet pipe 333 respectively, and then flows to the two water spraying parts 340.

[0078] Reference Figure 8 As shown, in a possible implementation, the water spray assembly 300 also includes a fixed bracket 350, the fixed bracket 350 is connected to the floor brush body 100, the driving pump 320 is connected to the fixed bracket 350, the fixed bracket 350 has a limiting area, and the diverter 330 is located in the limiting area.

[0079] In this way, the driving pump 320 can be installed to the floor brush body 100 through the fixed bracket 350, so that the driving pump 320 is fixedly connected relative to the floor brush body 100, and the diverter 330 can be restricted in the limiting area of ​​the fixed bracket 350, thereby preventing the diverter 330 from moving freely in the floor brush body 100.

[0080] Reference Figure 8As shown, in a specific implementation, the fixing bracket 350 has a first limiting rib 351 , a second limiting rib 352 and a third limiting rib 353 , and the first limiting rib 351 includes a first limiting section 3511 and a second limiting section 3512 that are connected to each other.

[0081] The extension direction of the first limiting section 3511 and the extension direction of the second limiting rib 352 are both consistent with the axial direction of the water inlet pipe 331, and the first limiting section 3511 and the second limiting rib 352 are located on both sides of the water inlet pipe 331, the extension direction of the second limiting section 3512 is consistent with the axial direction of the first water outlet pipe 332, the extension direction of the third limiting rib 353 is consistent with the axial direction of the second water outlet pipe 333, the second limiting section 3512 and the third limiting rib 353 are located on both sides of the first water outlet pipe 332, and the first limiting rib 351, the second limiting rib 352 and the third limiting rib 353 jointly define a limiting area.

[0082] In this way, the first limiting section 3511 and the second limiting rib 352 cooperate with each other to limit the radial displacement of the water inlet pipe 331, and the first limiting section 3511 and the third limiting rib 353 cooperate with each other to limit the radial displacement of the first water outlet pipe 332 and the second water outlet pipe 333. Since the water inlet pipe 331 is located between the first water outlet pipe 332 and the second water outlet pipe 333, when the radial displacement of the water inlet pipe 331 is limited, the axial displacement of the first water outlet pipe 332 and the second water outlet pipe 333 is also limited. When the radial displacement of the first water outlet pipe 332 and the second water outlet pipe 333 is limited, the axial displacement of the water inlet pipe 331 is also limited. In this way, the first limiting rib 351, the second limiting rib 352 and the third limiting rib 353 can jointly form a limiting area, thereby limiting the diverter 330 in the limiting area, thereby preventing the diverter 330 from moving arbitrarily in the floor brush body 100.

[0083] Reference Figure 3 As shown, in some embodiments, the two roller brushes 211 include a first roller brush 211a and a second roller brush 211b, and the two water spraying members 340 include a first water spraying member 340 and a second water spraying member 340. The first roller brush 211a is located at the front end of the moving direction of the floor brush 10, and the second roller brush 211b is located at the rear end of the moving direction of the floor brush 10. The first water spraying member 340 is arranged corresponding to the first roller brush 211a, and the second water spraying member 340 is arranged corresponding to the second roller brush 211b. The first water outlet pipe 332 is connected to the first water spraying member 340, and the second water outlet pipe 333 is connected to the second water spraying member 340. The inner diameter of the first water outlet pipe 332 is greater than the inner diameter of the second water outlet pipe 333.

[0084] It can be understood that when both roller brushes 211 are wet mopping, the first roller brush 211a located at the front end of the moving direction of the floor brush 10 requires a larger amount of liquid to fully wet the first roller brush 211a, thereby improving the cleaning effect of the first roller brush 211a, while the second roller brush 211b located at the rear end of the moving direction of the floor brush 10 requires a smaller amount of liquid to avoid leaving more water stains on the surface to be cleaned. Therefore, by making the inner diameter of the first water outlet pipe 332 larger than the inner diameter of the second water outlet pipe 333, the amount of liquid entering the first water spray member 340 is larger and the amount of liquid entering the second water spray member 340 is smaller, so that more cleaning liquid is sprayed to the first roller brush 211a and less cleaning liquid is sprayed to the second roller brush 211b.

[0085] In a possible implementation, the first water outlet pipe 332 extends in a direction pointing toward the first roller brush 211 a , and the second water outlet pipe 333 extends in a direction pointing toward the second roller brush 211 b .

[0086] Such a configuration is beneficial for shortening the distance between the first water outlet pipe 332 and the first roller brush 211a, and for shortening the distance between the second water outlet pipe 333 and the second roller brush 211b, thereby facilitating the cleaning liquid to quickly reach the first roller brush 211a and the second roller brush 211b.

[0087] In a possible implementation, the clean water tank 310 includes a first clean water tank and a second clean water tank, the first clean water tank is located in the first roller brush 211a, the second clean water tank is located in the second roller brush 211b, and the first clean water tank and the second clean water tank are connected to each other.

[0088] It is understandable that, compared with only one clean water tank 310, providing two clean water tanks 310 on the floor brush 10 can increase the cleaning liquid capacity of the floor brush 10, thereby improving the endurance of the floor brush 10 during wet mopping. When the floor brush 10 is working, since the first clean water tank and the second clean water tank are connected to each other, and the driving pump 320 is simultaneously connected to the first water spraying member 340 and the second water spraying member 340 through the diverter 330, the first clean water tank and the second clean water tank can provide cleaning liquid to the first water spraying member 340 and the second water spraying member 340.

[0089] Reference Figure 7 As shown, in a specific implementation, the clean water tank 310 includes a water tank body 311 and a first connecting part 312 which are connected to each other, the water tank body 311 has a water containing cavity, the first connecting part 312 is located at one end of the water tank body 311 facing the handle 212, the first connecting part 312 has a water flow channel, and the water flow channel is connected between the flow channel 2121 and the water containing cavity.

[0090] In this way, the water holding chamber can be used to store cleaning liquid, and the water flow channel can be used to connect the flow channel 2121 and the water holding chamber, so that the cleaning liquid in the water holding chamber flows through the water flow channel, the flow channel 2121, the driving pump 320, the diverter 330 and the water spraying member 340 in sequence, and is finally sprayed to the roller brush 211 through the water spray port, thereby wetting the roller brush 211.

[0091] Reference Figure 7 As shown, in a possible implementation, the roller brush unit 210 further includes a threaded connector 213, the handle 212 has a through hole 2122, the first connection portion 312 has a threaded connection hole, and the threaded connector 213 passes through the through hole 2122 and is threadedly connected to the threaded connection hole.

[0092] In this way, the first connecting part 312 can be fixedly connected to the handle piece 212 through the threaded connecting part 213, so that the clean water tank 310 is fixedly connected to the handle piece 212, 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 211, thereby preventing the cleaning liquid in the clean water tank 310 from shaking drastically and affecting the stability of the floor brush 10, and avoiding the clean water tank 310 from rotating with the roller brush 211 and increasing the power consumption of the floor brush 10.

[0093] Reference Figure 7 As shown, in some embodiments, the clean water tank 310 also includes a second connecting part 313, the first connecting part 312 and the second connecting part 313 are connected to both ends of the water tank body 311, the roller brush 211 is rotatably connected to the second connecting part 313, and the handle 212 is detachably connected to the floor brush body 100.

[0094] That is to say, one end of the clean water tank 310 is fixedly connected to the handle 212, and the other end of the clean water tank 310 is rotatably connected to the roller brush 211. In this way, the roller brush 211 can be rotatably connected to the handle 212, and then the roller brush 211 can be rotatably and detachably connected to the floor brush body 100.

[0095] Reference Fig. 9 As shown, in a possible implementation, the handle 212 also includes a first connector 2123, the first connector 2123 is connected to the end of the flow channel 2121 away from the clean water tank 310, the floor brush body 100 has a second connector 110, the second connector 110 is connected to the drive pump 320, and the first connector 2123 is connected to the second connector 110 by plugging.

[0096] In this way, when the roller brush unit 210 is installed on the floor brush body 100, the first joint 2123 is plugged and connected with the second joint 110, so that the clean water tank 310, the flow channel 2121, the driving pump 320, the diverter 330 and the water spraying part 340 are connected in sequence, thereby facilitating the cleaning liquid in the clean water tank 310 to enter the water spraying part 340 along the flow channel 2121, the driving pump 320 and the diverter 330 in sequence.

[0097] Reference Fig. 9 As shown, when the roller brush unit 210 is installed on the floor brush body 100, the flow channel 2121 needs to establish a connection with the driving pump 320, and when the roller brush unit 210 is removed from the floor brush body 100, the flow channel 2121 needs to be disconnected from the driving pump 320. Therefore, in a possible implementation, the roller brush unit 210 also includes a valve core 214 and an elastic member 215, the valve core 214 is movably arranged in the first joint 2123, the elastic member 215 is connected between the valve core 214 and the handle 212, and the elastic force direction of the elastic member 215 points to the valve core 214 to drive the valve core 214 to close the first joint 2123. A push rod 111 is provided in the second joint 110, and the push rod 111 abuts against the valve core 214 to drive the valve core 214 to open the first joint 2123.

[0098] In this way, when the roller brush unit 210 is installed on the floor brush body 100, the first joint 2123 is plugged into the second joint 110, and the top rod 111 abuts against the valve core 214, thereby driving the valve core 214 to move away from the second joint 110, thereby opening the first joint 2123, so that the clean water tank 310, the flow channel 2121, the drive pump 320, the diverter 330 and the water spraying part 340 are connected in sequence.

[0099] When the roller brush unit 210 is removed from the floor brush body 100, the first connector 2123 is disengaged from the second connector 110, the top rod 111 is disengaged from the valve core 214, and the elastic force of the elastic member 215 drives the valve core 214 to move toward the second connector 110, thereby blocking the first connector 2123, thereby disconnecting the flow channel 2121 and the drive pump 320. In this way, when the roller brush assembly 200 is removed from the floor brush body 100, the valve core 214 can automatically close the first connector 2123, thereby preventing leakage of cleaning liquid in the flow channel 2121 and the clean water tank 310.
