Description

Technical Field

[0001] This application relates to the technical field of environmental cleaning appliances, and particularly relates to a floor brush and a cleaning device. Background Art

[0002] With the development of technology and the improvement of living standards, household cleaning appliances such as vacuum cleaners and floor washers have become more and more popular, and their functions have also become more and more diverse. Taking the floor washer as an example, in addition to the vacuuming function, the floor washer also has a mopping function.

[0003] In the related art, a floor washer mainly includes a main body and a floor brush. The floor brush can suck away dust and impurities on the ground through the negative pressure suction generated by the main body. 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 moisten the mopping roller brush, and then deeply clean the ground. However, since not only the roller brush but also the water tank need to be arranged on the floor brush, the volume of the floor brush is relatively large. Utility Model Content

[0004] Based on this, this application provides a floor brush and a cleaning device to solve the deficiencies in the related art.

[0005] In a first aspect, this application provides a floor brush, which includes a floor brush body and a cleaning component. The cleaning component includes a roller brush assembly and a clean water tank. The roller brush assembly includes a roller brush. The roller brush includes a barrel body and a driving connection part that are connected to each other. The driving connection part is located at the first end of the barrel body, and the clean water tank is located inside the barrel body;

[0006] The clean water tank includes a water tank body and a second connection part that are connected to each other. The driving connection part is rotatably connected to the floor brush body, and the second connection part is fixedly connected to the floor brush body.

[0007] The floor brush provided by the embodiment of this application is provided with a floor brush body for installing the cleaning component and other components, a barrel body for rolling contact with the surface to be cleaned to clean the surface to be cleaned, a driving connection part for rotatably connecting with the floor brush body, so that the roller brush is rotatably arranged relative to the floor brush body, a water tank body for accommodating the cleaning liquid, and a second connection part for fixedly connecting with the floor brush body, so that the clean water tank is statically arranged relative to the floor brush body, and the roller brush is rotatably arranged relative to the clean water tank, thereby avoiding the clean water tank rotating together with the roller brush. Thus, for the floor brush provided by this application, the clean water tank is integrated into the roller brush, which can effectively reduce the volume of the floor brush, and the clean water tank does not rotate together with the roller brush, thereby improving the stability of the floor brush during use and reducing the power consumption of the floor brush.

[0008] In a possible implementation, the roller brush assembly further includes a handle part. The second connection part is fixedly connected to the handle part, and the handle part is detachably connected to the floor brush body.

[0009] In this way, the second connecting portion can be detachably connected to the floor brush body through the handle member, and then the second connecting portion can be statically connected to the floor brush body, so that the water tank is statically arranged relative to the floor brush body, thereby preventing the water tank from rotating together with the roller brush.

[0010] In a possible implementation, the roller brush assembly further includes a threaded fastener. The handle member has a through hole, and the second connecting portion has a threaded connection hole. Both the through hole and the threaded connection hole extend along the axial direction of the cylinder body. The threaded fastener passes through the through hole and is threadedly connected to the threaded connection hole.

[0011] In this way, the second connecting portion can be fixedly connected to the handle member through the threaded fastener, and then the water tank is fixedly connected to the handle member, so that the water tank is statically arranged relative to the floor brush body.

[0012] In a possible implementation, the roller brush assembly further includes a driven rotation unit. The driven rotation unit is arranged at the second end of the cylinder body, and the cylinder body is rotationally connected to the second connecting portion through the driven rotation unit.

[0013] In this way, the first end of the cylinder body can be rotationally connected to both the floor brush body and the first connecting portion through the driving connection portion, and the first end of the cylinder body can be rotationally connected to the second connecting portion through the driven rotation unit. Furthermore, rotational supports can be provided at both ends of the cylinder body, thereby improving the stability of the cylinder body during rotation.

[0014] In a possible implementation, the driven rotation unit includes a first bearing member. The first bearing member is located between the second connecting portion and the cylinder body. The first bearing member is fixedly connected to one of the second connecting portion and the cylinder body, and the other of the second connecting portion and the cylinder body is rotationally connected to the first bearing member.

[0015] In this way, by providing the first bearing member between the second connecting portion and the cylinder body to support the second end of the cylinder body, the stability of the cylinder body during rotation is improved.

[0016] In a possible implementation, the driven rotation unit further includes an end cap. The second end of the cylinder body is provided with an open end, and the end cap is connected to the second end of the cylinder body;

[0017] The end cap includes a blocking portion. The second connecting portion is inserted into the blocking portion. The first bearing member is located between the blocking portion and the second connecting portion. The blocking portion is in interference fit with the first bearing member. The first bearing member is rotationally connected to the second connecting portion, and the blocking portion is fixedly connected to the cylinder body.

[0018] In this way, a sealing portion is arranged on the outer sleeve of the first bearing, and the sealing portion is interference-connected with the first bearing component, so that the first bearing component and the cylinder body are fixedly connected through the sealing portion, and then the first bearing component is fixedly connected to the cylinder body, and the first bearing component is rotatably connected to the second connecting portion, so that the second end of the cylinder body is rotatably connected to the second connecting portion through the end cover and the first bearing component.

[0019] In a possible implementation, the driven rotating unit further includes an elastic ring, the sealing portion has an annular groove, the elastic ring is sleeved in the annular groove, and the elastic ring elastically abuts between the cylinder and the sealing portion.

[0020] In this way, after the elastic ring is sleeved on the sealing part, the elastic ring elastically abuts between the sealing part and the cylinder body, and the elastic ring can fill the gap between the sealing part and the cylinder body, so that the sealing part is fixedly connected to the cylinder body through the elastic ring, so that the cylinder body drives the end cover to rotate synchronously relative to the second connecting part.

[0021] In a possible implementation, the end cover further includes a limiting portion, the limiting portion is connected to an end of the blocking portion away from the first connecting portion, and the limiting portion abuts against an end surface of the cylinder.

[0022] In this way, when the end cover is assembled to the cylinder, the sealing part can be inserted into the cylinder, and the sealing part can be fixedly connected to the cylinder by an elastic ring, and the limiting part can abut against the end face of the second end of the cylinder to limit the insertion depth of the sealing part, thereby improving the assembly accuracy and assembly efficiency of the end cover.

[0023] In a possible implementation, the clean water tank further includes a first connection portion, the first connection portion and the second connection portion are connected to opposite ends of the water tank body, and the driving connection portion is rotatably connected to the first connection portion.

[0024] In this way, the roller brush can be rotatably connected to the first connection part through the driving connection part, thereby ensuring stability when the roller brush rotates, thereby increasing the service life of the floor brush.

[0025] In a possible implementation, the roller brush assembly further includes a second bearing member, the first connecting portion has a rotating cavity, the driving connecting portion includes a rotating shaft, the second bearing member is inserted into the rotating cavity, and the rotating shaft is rotatably connected to the second bearing member.

[0026] In this way, a rotating cavity is set in the first connecting part for inserting the rotating shaft, so that the driving connecting part is rotatably connected to the first connecting part. A second bearing member is set between the rotating cavity and the rotating shaft, so that the rotating shaft can be supported by the second bearing member, so that the rotation of the first end of the cylinder is more stable and smooth.

[0027] In a possible implementation, the water tank body defines a water containing chamber, and the rotating chamber is located in the water containing chamber.

[0028] In this way, the water storage cavity can be used to store the cleaning liquid, and the rotating cavity and the water storage cavity are arranged from the inside to the outside along the circumferential direction of the cylinder body. Furthermore, the first connecting part can be prevented from protruding out of the water tank body, so that after the water tank and the roller brush are assembled together, the dimension of the cleaning component along the axial direction of the roller brush is smaller, and the structure of the floor brush is more compact.

[0029] In a possible implementation manner, the second connecting part further has a water flow channel, and the water flow channel communicates with both the inside and the outside of the water tank body.

[0030] In this way, when it is necessary to replenish the cleaning liquid in the water tank, the cleaning liquid can be injected into the water tank through the water flow channel. Or, when the floor brush is working and it is necessary to spray the cleaning liquid from the water tank to the roller brush or the surface to be cleaned, the cleaning liquid can flow out through the water flow channel.

[0031] In a possible implementation manner, the driving connecting part is located inside the cylinder body.

[0032] In this way, the dimension of the cleaning component along the axial direction of the cylinder body can be reduced, and further the volume of the floor brush can be reduced.

[0033] In a possible implementation manner, there is a gap between the outer side wall of the water tank body and the inner side wall of the cylinder body.

[0034] In this way, when the cylinder body rotates, friction between the outer side wall of the water tank body and the inner side wall of the cylinder body can be avoided, and further the rotation of the cylinder body can be prevented from being hindered by the water tank body.

[0035] In a possible implementation manner, the number of cleaning components is two, and the two cleaning components are arranged at intervals along the traveling direction of the floor brush.

[0036] In this way, the cleaning effect and cleaning efficiency of the floor brush can be improved, and since the floor brush has two water tanks, the cleaning liquid capacity of the floor brush can be increased, and further the endurance of the floor brush during wet mopping can be improved.

[0037] In a second aspect, the present application provides a cleaning device, including a device main body and the floor brush provided in the first aspect above, and the floor brush is connected to the device main body.

[0059] In the description and claims of this application and the above-mentioned drawings, the terms "first", "second", "third" (if any) are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0060] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or display comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or displays.

[0061] In the related art, a floor washer mainly includes a main body and a floor brush. The floor brush can suck away dust and impurities on the ground through the negative pressure suction generated by the main body. In addition, a mopping roller brush and a water tank can be arranged on the floor brush. The water tank can supply water to the mopping roller brush to moisten the mopping roller brush, and then deeply clean the ground. However, since not only the roller brush but also the water tank need to be arranged on the floor brush, the volume of the floor brush is relatively large.

[0062] In view of this, the embodiments of the present application provide a floor brush and a cleaning device. Among them, the 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 clean water tank is fixedly connected to the floor brush body to prevent the clean water tank from rotating together with the roller brush.

[0063] The following will describe in detail the specific embodiments of the floor brush and the cleaning device provided by the embodiments of the present application with reference to the accompanying drawings.

[0064] Refer to Figure 1 As shown, the embodiments of the present application provide a cleaning device, including a device main body 20 and a floor brush 10, and the floor brush 10 is connected to the device main body 20.

[0065] Among them, the floor brush 10 is used to contact the surface to be cleaned, thereby cleaning the surface to be cleaned. The device main body 20 can provide suction 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 operations such as vacuuming and mopping on the surface to be cleaned.

[0066] Refer to Figures 2 to 10As shown in the figure, specifically, the floor brush 10 provided in the implementation of the present application includes a floor brush body 100 and a cleaning component 200. The cleaning component 200 includes a roller brush assembly 210 and a water tank 220. The roller brush assembly 210 includes a roller brush 211. The roller brush 211 includes a barrel 2111 and a driving connection part 2112 that are connected to each other. The driving connection part 2112 is located at the first end of the barrel 2111, and the water tank 220 is located inside the barrel 2111.

[0067] The water tank 220 includes a water tank body 221, a first connection part 222, and a second connection part 223. The first connection part 222 and the second connection part 223 are connected to opposite ends of the water tank body 221. One end of the driving connection part 2112 is rotatably connected to the floor brush body 100, and the other end of the driving connection part 2112 is rotatably connected to the first connection part 222. The second connection part 223 is fixedly connected to the floor brush body 100.

[0068] In the present application, the floor brush body 100 is used to install the cleaning component 200, and the cleaning component 200 is used to clean the surface to be cleaned. Specifically, the cleaning component 200 may include a roller brush assembly 210 and a water tank 220. The roller brush assembly 210 includes a roller brush 211. When the roller brush 211 rolls, the outer surface of the roller brush 211 is used to contact the surface to be cleaned, so as to scrub the surface to be cleaned, or assist in sucking away the dirt on the surface to be cleaned. The water tank 220 is used to store the cleaning liquid and supply the cleaning liquid to the roller brush 211 to moisten the outer surface of the roller brush 211, so as to facilitate the roller brush 211 to deeply clean the surface to be cleaned, or to self-clean the roller brush 211 through the cleaning liquid.

[0069] In order to make the overall structure of the floor brush 10 more compact, the water tank 220 can be arranged inside the roller brush 211 so that the cleaning component 200 is assembled on the floor brush body 100. In this way, the water tank 220 and the roller brush 211 share part of the space, and thus the volume of the floor brush 10 can be effectively reduced.

[0070] It can be understood that since the cleaning liquid in the water tank 220 cannot maintain a fixed shape and the volume of the cleaning liquid will gradually decrease as the cleaning work progresses, if the water tank 220 rotates with the roller brush 211, the cleaning liquid will shake greatly in the water tank 220, resulting in unstable use of the floor brush 10. In addition, compared with only driving a single roller brush 211 to rotate, driving the roller brush 211 and the water tank 220 to rotate together requires more energy consumption, thereby increasing the ineffective power consumption of the floor brush 10.

[0071] Therefore, in the floor brush 10 of the embodiment of the present application, the rotary brush 211 is rotatably arranged relative to the floor brush body 100, while the water tank 220 is statically arranged relative to the floor brush body 100. Specifically, the rotary brush 211 may include a cylinder body 2111 and a driving connection part 2112 which are connected to each other. The water tank 220 may include a water tank body 221, a first connection part 222 and a second connection part 223 connected to both ends of the water tank body 221. The water tank body 221 is used to contain the cleaning liquid, and the shape of the water tank body 221 matches that of the cylinder body 2111 to increase the capacity of the water tank 220. The second connection part 223 is statically connected to the floor brush body 100. That is to say, the second connection part 223 may be fixedly connected or detachably connected to the floor brush body 100, as long as the second connection part 223 is statically arranged relative to the floor brush body 100. The driving connection part 2112 is used to connect to a driving component arranged on the floor brush body 100, and then drive the rotary brush 211 to rotate through the driving component. And the driving connection part 2112 may be rotatably connected to the first connection part 222 and the second connection part 223, thereby improving the stability of the rotary brush 211 when rotating. In this way, the rotary brush 211 may be rotatably arranged relative to the water tank 220. Then, when the floor brush 10 works, the rotary brush 211 rotates, but the water tank 220 does not rotate together with the rotary brush 211.

[0072] The floor brush 10 provided by the embodiment of the present application includes a floor brush body 100 and a cleaning component 200. The cleaning component 200 includes a rotary brush assembly 210 and a water tank 220. The rotary brush assembly 210 includes a rotary brush 211. The rotary brush 211 includes a cylinder body 2111 and a driving connection part 2112. The water tank 220 includes a water tank body 221, a first connection part 222 and a second connection part 223. By arranging the floor brush body 100 for installing the cleaning component 200 and other components, by arranging the cylinder body 2111 for rolling contact with the surface to be cleaned to clean the surface to be cleaned, by arranging the driving connection part 2112 for rotatably connecting to the floor brush body 100, so that the rotary brush 211 is rotatably arranged relative to the floor brush body 100, by arranging the water tank body 221 for containing the cleaning liquid, by arranging the second connection part 223 for statically connecting to the floor brush body 100, and by arranging the first connection part 222 for rotatably connecting to the driving connection part 2112, so that the water tank 220 is statically arranged relative to the floor brush body 100, while the rotary brush 211 is rotatably arranged relative to the water tank 220, thus avoiding the water tank 220 rotating together with the rotary brush 211. Therefore, in the floor brush 10 provided by the embodiment of the present application, the water tank 220 is integrated into the rotary brush 211, which can effectively reduce the volume of the floor brush 10, and the water tank 220 does not rotate together with the rotary brush 211, thereby improving the stability of the floor brush 10 during use and reducing the power consumption of the floor brush 10.

[0073] Refer to Figures 3 to 6As shown, in a possible implementation, the roller brush assembly 210 further includes a handle member 212. The second connecting portion 223 is fixedly connected to the handle member 212, and the handle member 212 is detachably connected to the floor brush body 100.

[0074] In this way, the second connecting portion 223 can be detachably connected to the floor brush body 100 through the handle member 212, so that the second connecting portion 223 is statically connected to the floor brush body 100, and further the water tank 220 is statically arranged relative to the floor brush body 100, thereby preventing the water tank 220 from rotating together with the roller brush 211.

[0075] Referring to Figures 5 to 7 、 Figure 10 As shown, in some embodiments, the roller brush assembly 210 further includes a threaded fastener 213. The handle member 212 has a through hole 2121, and the second connecting portion 223 has a threaded connection hole 2231. The through hole 2121 and the threaded connection hole 2231 both extend along the axial direction of the cylinder body 2111, and the threaded fastener 213 passes through the through hole 2121 and is threadedly connected to the threaded connection hole 2231.

[0076] In this way, the second connecting portion 223 can be fixedly connected to the handle member 212 through the threaded fastener 213, so that the water tank 220 is fixedly connected to the handle member 212, thereby making the water tank 220 statically arranged relative to the floor brush body 100.

[0077] In addition, since the water tank 220 is fixedly connected to the handle member 212 by means of threaded connection, the water tank 220 and the roller brush assembly 210 can be assembled to form the cleaning component 200. The handle member 212 is detachably connected to the floor brush body 100. When needed, the handle member 212 can be separated from the floor brush body 100, and then the cleaning component 200 can be detached from the floor brush body 100 as a whole.

[0078] Referring to Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 And Figure 9 As shown, in order to improve the stability of the roller brush 211 during rotation, in a possible implementation, the roller brush assembly 210 further includes a driven rotation unit 214. The driven rotation unit 214 is arranged at the second end of the cylinder body 2111, and the cylinder body 2111 is rotationally connected to the second connecting portion 223 through the driven rotation unit 214.

[0079] In this way, the first end of the cylinder body 2111 can be rotatably connected to both the floor brush body 100 and the first connecting portion 222 through the driving connection portion 2112. The first end of the cylinder body 2111 can be rotatably connected to the second connecting portion 223 through the driven rotating unit 214. Thus, both ends of the cylinder body 2111 have rotational supports, which can improve the stability of the cylinder body 2111 during rotation.

[0080] Referring to Figure 3 and Figure 7 As shown, in a possible implementation, the driven rotating unit 214 includes a first bearing member 2141. The first bearing member 2141 is located between the second connecting portion 223 and the cylinder body 2111. The first bearing member 2141 is fixedly connected to one of the second connecting portion 223 and the cylinder body 2111, and the other of the second connecting portion 223 and the cylinder body 2111 is rotatably connected to the first bearing member 2141.

[0081] For example, the first bearing member 2141 is fixedly connected to the second connecting portion 223, and the cylinder body 2111 is rotatably connected to the first bearing member 2141. Or, the first bearing member 2141 is fixedly connected to the cylinder body 2111, and the cylinder body 2111 is rotatably connected to the second connecting portion 223. In this way, by providing the first bearing member 2141 between the second connecting portion 223 and the cylinder body 2111 to support the second end of the cylinder body 2111, the stability of the cylinder body 2111 during rotation is improved.

[0082] Referring to Figure 3 and Figure 7 and Figure 11 As shown, in some embodiments, the driven rotating unit 214 further includes an end cap 2142. The second end of the cylinder body 2111 is provided with an open end, and the end cap 2142 is connected to the second end of the cylinder body 2111.

[0083] The end cap 2142 includes a blocking portion 2142a. The second connecting portion 223 is inserted into the blocking portion 2142a. The first bearing member 2141 is located between the blocking portion 2142a and the second connecting portion 223. The blocking portion 2142a is in interference fit with the first bearing member 2141. The first bearing member 2141 is rotatably connected to the second connecting portion 223, and the blocking portion 2142a is fixedly connected to the cylinder body 2111.

[0084] In this way, by disposing a sealing portion 2142a on the first bearing sleeve and making the sealing portion 2142a interference-connected with the first bearing member 2141, the first bearing member 2141 and the cylinder 2111 are fixedly connected through the sealing portion 2142a, so that the first bearing member 2141 is fixedly connected to the cylinder 2111, and the first bearing member 2141 is rotatably connected to the second connecting portion 223, so that the second end of the cylinder 2111 is rotatably connected to the second connecting portion 223 through the end cover 2142 and the first bearing member 2141.

[0085] Reference Figure 3 , Figure 7 and Figure 11 As shown, in a possible implementation, the driven rotating unit 214 further includes an elastic ring 2143, the blocking portion 2142a has an annular groove 2142b, the elastic ring 2143 is sleeved in the annular groove 2142b, and the elastic ring 2143 elastically abuts between the cylinder 2111 and the blocking portion 2142a.

[0086] In this way, after the elastic ring 2143 is sleeved on the sealing part 2142a, since the elastic ring 2143 elastically abuts between the sealing part 2142a and the cylinder 2111, the elastic ring 2143 can fill the gap between the sealing part 2142a and the cylinder 2111, and then the sealing part 2142a is fixedly connected to the cylinder 2111 through the elastic ring 2143, so that the cylinder 2111 drives the end cover 2142 to rotate synchronously relative to the second connecting part 223.

[0087] Reference Figure 3 , Figure 7 and Figure 11 As shown, in some embodiments, the end cover 2142 further includes a limiting portion 2142c, which is connected to an end of the blocking portion 2142a away from the first connecting portion 222, and the limiting portion 2142c abuts against the end surface of the cylinder 2111.

[0088] In this way, when the end cover 2142 is assembled to the cylinder 2111, the sealing portion 2142a can be inserted into the cylinder 2111, and the sealing portion 2142a can be fixedly connected to the cylinder 2111 by the elastic ring 2143, and the limiting portion 2142c can abut against the end face of the second end of the cylinder 2111 to limit the insertion depth of the sealing portion 2142a, thereby improving the assembly accuracy and assembly efficiency of the end cover 2142.

[0089] Reference Figure 8 and Figure 9As shown, in some embodiments, the roller brush assembly 210 further includes a second bearing member 215. The first connecting portion 222 has a rotating cavity 2221. The driving connecting portion 2112 includes a rotating shaft 2112a. The second bearing member 215 is inserted into the rotating cavity 2221, and the rotating shaft 2112a is rotatably connected to the second bearing member 215.

[0090] In this way, by providing the rotating cavity 2221 in the first connecting portion 222 for the rotating shaft 2112a to be inserted, the driving connecting portion 2112 is rotatably connected to the first connecting portion 222. By providing the second bearing member 215 between the rotating cavity 2221 and the rotating shaft 2112a, the rotating shaft 2112a can be supported by the second bearing member 215, so that the first end of the barrel 2111 rotates more stably and smoothly.

[0091] Both the first end and the second end of the barrel 2111 have rotational supports, and it rotates more balancedly, and the roller brush 211 is not easily worn, which can improve the service life of the floor brush 10.

[0092] Refer to Figure 6 And Figure 9 As shown, in a possible implementation, the water tank body 221 defines a water storage cavity 2211, and the rotating cavity 2221 is located inside the water storage cavity 2211.

[0093] With such a setting, the water storage cavity 2211 can be used to hold the cleaning liquid, and the rotating cavity 2221 and the water storage cavity 2211 are arranged from inside to outside along the circumference of the barrel 2111, which can avoid the first connecting portion 222 protruding outside the water tank body 221. Thus, after the water tank 220 and the roller brush 211 are assembled together, the size of the cleaning component 200 along the axial direction of the roller brush 211 is smaller, and the structure of the floor brush 10 is more compact.

[0094] Refer to Figure 10 As shown, in some embodiments, the second connecting portion 223 further has a water flow channel 2232, and the water flow channel 2232 communicates with both the inside and outside of the water tank body 221.

[0095] In this way, when it is necessary to replenish the cleaning liquid in the water tank 220, the cleaning liquid can be injected into the water tank 220 through the water flow channel 2232. Or, when the floor brush 10 is working and it is necessary to spray the cleaning liquid from the water tank 220 to the roller brush 211 or the surface to be cleaned, the cleaning liquid can flow out through the water flow channel 2232.

[0096] In a possible implementation, the driving connection part 2112 is located inside the cylinder body 2111. That is to say, the driving connection part 2112 is located inside the first end of the cylinder body 2111. Compared with setting the driving connection part 2112 outside the cylinder body 2111, setting the driving connection part 2112 inside the cylinder body 2111 can reduce the size of the cleaning component 200 along the axial direction of the cylinder body 2111, and further reduce the volume of the floor brush 10.

[0097] In some embodiments, there is a gap between the outer side wall of the water tank body 221 and the inner side wall of the cylinder body 2111. With such a setting, when the cylinder body 2111 rotates, friction between the outer side wall of the water tank body 221 and the inner side wall of the cylinder body 2111 can be avoided, and further, the water tank body 221 can be prevented from interfering with the rotation of the cylinder body 2111.

[0098] In a possible implementation, the number of the cleaning components 200 is two, and the two cleaning components 200 are arranged at intervals along the traveling direction of the floor brush 10.

[0099] It should be understood that when two cleaning components 200 are arranged at intervals along the traveling direction of the floor brush 10 itself, the roller brush 211 of one cleaning component 200 can be used for dry suction, and the roller brush 211 of the other cleaning component 200 can be used for wet mopping, or the roller brushes 211 of the two cleaning components 200 are both used for wet mopping. The embodiments of the present application do not limit this. With such a setting, the cleaning effect and cleaning efficiency of the floor brush 10 can be improved, and the floor brush 10 has two clean water tanks 220, which can increase the cleaning liquid capacity of the floor brush 10, and further improve the endurance of the floor brush 10 during wet mopping.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
