Description

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

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

[0003] In the relevant art, a floor washer mainly comprises a main unit and a floor brush. The floor brush can suck away dust and debris on a floor by means of a negative pressure suction force generated by the main unit. In addition, the floor brush can be further provided with a floor-mopping roller brush and a water tank. The water tank can supply water to the floor-mopping roller brush so as to humidify the floor-mopping roller brush, before cleaning a floor thoroughly. However, as the floor brush needs to be provided with not only a roller brush, but also a water tank, the floor brush is relatively larger in size.

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

[0005] In a first aspect, the present application provides a floor brush, the floor brush comprising a floor brush body and a cleaning part, the cleaning part comprising a roller brush assembly and a clean water tank, the roller brush assembly comprising a roller brush, the roller brush comprising a cylinder and a driving connecting part which are connected to each other, the driving connecting part being located at a first end of the cylinder, the clean water tank being located inside the cylinder;

[0006] Wherein the clean water tank comprises a water tank body and a second connecting part which are connected to each other, the driving connecting part being rotatably connected to the floor brush body, the second connecting part being statically connected to the floor brush body.

[0007] The floor brush provided by embodiments of the present application provides the floor brush body for mounting the cleaning part and other parts, provides the cylinder for rolling contact with a surface to be cleaned so as to clean the surface to be cleaned, provides the driving connecting part for rotary connection with the floor brush body so that the roller brush is rotatably arranged relative to the floor brush body, provides the water tank body for containing a cleaning liquid, provides the second connecting part for statical connection with the floor brush body so that the clean water tank is arranged statically relative to the floor brush body. And as the roller brush is rotatably arranged relative to the clean water tank, the clean water tank is prevented from rotating with the roller brush. Thus, with the floor brush provided by the present application, as the clean water tank is integrated inside the roller brush, the volume of the floor brush can be effectively reduced, and the clean water tank does not rotate with the roller brush, thereby increasing the stability of the floor brush during use and reducing the power consumption of the floor brush.

[0008] In a possible mode of realization, the roller brush assembly further comprises a handle member, the second connecting part being fixedly connected to the handle member, the handle member being removably connected to the floor brush body.

[0009] Thus, the second connecting part can be removably connected to the floor brush body by means of the handle member, so that the second connecting part is statically connected to the floor brush body, and thus 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.

[0010] In a possible mode of realization, the roller brush assembly further comprises a threaded fastener, the handle member has a through hole, and the second connecting part has a threaded connecting hole, the through hole and the threaded connecting hole both extending along an axial direction of the cylinder, the threaded fastener passing through the through hole to threadedly connect to the threaded connecting hole.

[0011] Thus, the second connecting part can be fixedly connected to the handle member by means of the threaded fastener, so that the clean water tank is fixedly connected to the handle member, thereby arranging the clean water tank statically relative to the floor brush body.

[0012] In a possible mode of realization, the roller brush assembly further comprises a driven rotating unit, the driven rotating unit being arranged at a second end of the cylinder, the cylinder being rotatably connected to the second connecting part by means of the driven rotating unit.

[0013] Thus, the first end of the cylinder can be rotatably connected to the floor brush body and the first connecting part at the same time by means of the driving connecting part, and the second end of the cylinder can be rotatably connected to the second connecting part by means of the driven rotating unit, so that two ends of the cylinder can have rotation support, thereby increasing the stability of the cylinder during rotation.

[0014] In a possible mode of realization, the driven rotating unit comprises a first bearing member, the first bearing member being located between the second connecting part and the cylinder, the first bearing member being fixed to one of the second connecting part and the cylinder, the other of the second connecting part and the cylinder being rotatably connected to the first bearing member.

[0015] Thus, by providing the first bearing member between the second connecting part and the cylinder, the first bearing member supports the second end of the cylinder, thereby increasing the stability of the cylinder during rotation.

[0016] In a possible mode of realization, the driven rotating unit further comprises an end lid, the second end of the cylinder being arranged to be open, the end lid covering the second end of the cylinder;

[0017] Wherein the end lid comprises a blocking part, the second connecting part being configured to be inserted in the blocking part, the first bearing member being located between the blocking part and the second connecting part, the blocking part being interference fit with the first bearing member, the first bearing member being rotatably connected to the second connecting part, the blocking part being fixedly connected to the cylinder.

[0018] Thus, by sleeving the blocking part on the first bearing member, and interference fitting the blocking part with the first bearing member, the first bearing member and the cylinder are fixedly connected by means of the blocking part, so as to fixedly connect the first bearing member to the cylinder, and so as to rotatably connect the first bearing member to the second connecting part, thereby rotatably connecting the second end of the cylinder to the second connecting part by means of the end lid and the first bearing member.

[0019] In a possible mode of realization, the driven rotating unit further comprises a elastic ring, and the blocking part has a ring-shaped groove, the elastic ring being sleeved to the ring-shaped groove, and the elastic ring abutting elastically between the cylinder and the blocking part.

[0020] Thus, with the elastic ring sleeved on the blocking part, as the elastic ring abuts elastically between the blocking part and the cylinder, the elastic ring can fill the gap between the blocking part and the cylinder, so that the blocking part is fixedly connected to the cylinder by means of the elastic ring, thereby the cylinder drives the end lid to rotate in a synchronized way relative to the second connecting part.

[0021] In a possible mode of realization, the end lid further comprises a limiting part, the limiting part being connected to an end of the blocking part away from the first connecting part, the limiting part abutting against an end surface of the cylinder.

[0022] Thus, when the end lid is assembled to the cylinder, the blocking part can be inserted into the cylinder, and the blocking part can be fixedly connected to the cylinder by means of the elastic ring, while the limiting part can abut against the end surface of the second end of the cylinder, thereby limiting the insertion depth of the blocking part, and thus increasing assembly precision and assembly efficiency of the end lid.

[0023] In a possible mode of realization, the clean water tank further comprises a first connecting part, the first connecting part and the second connecting part being connected to two opposite ends of the water tank body, the driving connecting part being rotatably connected to the first connecting part.

[0024] Thus, the roller brush can be rotatably connected to the first connecting part by means of the driving connecting part, so as to increase the stability of the roller brush during rotation and thus prolong the service life of the floor brush.

[0025] In a possible mode of realization, the roller brush assembly further comprises a second bearing member, the first connecting part has a rotation cavity, and the driving connecting part comprises a rotary shaft, the second bearing member being insertion connected to the rotation cavity, the rotary shaft being rotatably connected to the second bearing member.

[0026] Thus, by providing the rotation cavity at the first connecting part for the rotary shaft to be inserted into, the driving connecting part is rotatably connected to the first connecting part. By providing the second bearing member between the rotation cavity and the rotary shaft, the rotary shaft can be supported by the second bearing member, so that the rotation of the first end of the cylinder is more stable and smoother.

[0027] In a possible mode of realization, the water tank body defines a water containing chamber, the rotation cavity being located in the water containing chamber.

[0028] Thus, the water containing chamber can be used to contain a cleaning liquid, and with the rotation cavity and the water containing chamber being arranged from inside to outside along the peripheral direction of the cylinder, the first connecting part can be prevented from protruding out of the water tank body, so that after the clean water tank and the roller brush are assembled together, the size of the cleaning part along the axial direction of the roller brush is relatively small, and the structure of the floor brush is more compact.

[0029] In a possible mode of realization, the second connecting part further has a water flow channel, the water flow channel being connected to both the inside and outside of the water tank body.

[0030] Thus, when the clean water tank needs to be replenished with a cleaning liquid, the cleaning liquid can be injected into the clean water tank by means of the water flow channel, or, when the floor brush is in operation and the cleaning liquid needs to sprayed towards the roller brush or a surface to be cleaned from the clean water tank, the cleaning liquid can flow out via the water flow channel.

[0031] In a possible mode of realization, the driving connecting part is located inside the cylinder.

[0032] Thus, the size of the cleaning part along the axial direction of the cylinder can be reduced, thereby reducing the volume of the floor brush.

[0033] In a possible mode of realization, a gap is provided between the outer side wall of the water tank body and the inner side wall of the cylinder.

[0034] Thus, friction between the outer side wall of the water tank body and the inner side wall of the cylinder when the cylinder rotates can be prevented. Thus, the water tank body can be prevented from obstructing the rotation of the cylinder.

[0035] In a possible mode of realization, two cleaning parts are provided, the two cleaning parts being arranged at intervals along an advancing direction of the floor brush.

[0036] Thus, the floor brush's cleaning effect and cleaning efficiency can be increased, and as the floor brush has two clean water tanks, the volume of the cleaning liquid of the floor brush can be increased, thereby improving the lasting capacity of the floor brush during wet mopping.

[0037] In a second aspect, the present application provides a cleaning device, comprising a device main unit and the floor brush provided by the first aspect described above, the floor brush being connected to the device main unit.

[0044] The terms "first," "second," and "third" (if any) in the specification and claims of the present application and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0045] In addition, the terms "comprise / include" and "have," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or display.

[0046] In the relevant art, a floor washer mainly comprises a main unit and a floor brush. The floor brush can suck away dust and debris on a floor by means of negative suction force generated by the main unit. In addition, the floor brush can be provided with a floor-mopping roller brush and a water tank. The water tank can supply water to the floor-mopping roller brush, so as to humidify the floor-mopping roller brush, before cleaning a floor thoroughly. However, as the floor brush needs to be provided with not only the roller brush but also the water tank, the floor brush is relatively larger in size.

[0047] In view of the above, embodiments of the present application provide a floor brush and a cleaning device, wherein, a clean water tank is provided in a roller brush, so that the clean water tank and the roller brush share partially a space, thereby reducing the size(volume) of the floor brush, and the clean water tank is statically connected to a floor brush body, so as to prevent the clean water tank from rotating with the roller brush.

[0048] Specific modes of realization of the floor brush and the cleaning device provided by embodiments of the present application are described in detail in conjunction with the accompanying drawings.

[0049] In reference to Fig. 1, an embodiment of the present application provides a cleaning device, comprising a device main unit 20 and a floor brush 10. The floor brush 10 is connected to the device main unit 20.

[0050] The floor brush 10 is used to come into contact with a surface to be cleaned, so as to clean the surface to be cleaned. The device main unit 20 can 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 operations such as vacuuming and mopping the surface to be cleaned.

[0051] In reference to Figs. 2 to 10, specifically, the floor brush 10 provided by the embodiment of the present application comprises a floor brush body 100 and a cleaning part 200. The cleaning part 200 comprises a roller brush assembly 210 and a clean water tank 220. The roller brush assembly 210 comprises a roller brush 211. The roller brush 211 comprises a cylinder 2111 and a driving connecting part 2112 which are connected to each other. The driving connecting part 2112 is located at a first end of the cylinder 2111. The clean water tank 220 is located inside the cylinder 2111.

[0052] The clean water tank 220 comprises a water tank body 221, a first connecting part 222 and a second connecting part 223. The first connecting part 222 and the second connecting part 223 are connected to two opposite ends of the water tank body 221. One end of the driving connecting part 2112 is rotatably connected to the floor brush body 100, the other end of the driving connecting part 2112 is rotatably connected to the first connecting part 222. The second connecting part 223 is statically connected to the floor brush body 100.

[0053] In the present application, the floor brush body 100 is configured to mount the cleaning part 200. The cleaning part 200 is used to clean a surface to be cleaned. Specifically, the cleaning part 200 can comprise the roller brush assembly 210 and the clean water tank 220. The roller brush assembly 210 comprises a roller brush 211. When the roller brush 211 rotates, an outer surface of the roller brush 211 comes into contact with the surface to be cleaned, thus wiping and cleaning the surface to be cleaned, or assist in sucking away dirt from the surface to be cleaned. The clean water tank 220 is used to store a cleaning liquid and provide the cleaning liquid to the roller brush 211, so as to humidify the outer surface of the roller brush 211 and thus help the roller brush 211 clean thoroughly the surface to be cleaned, or to clean the roller brush 211 itself using the cleaning liquid.

[0054] In order to render the overall structure of the floor brush 10 more compact, the clean water tank 220 can be arranged inside the roller brush 211, so as to form the cleaning part 200 assembled on the floor brush body 100. In this way, the clean water tank 220 and the roller brush 211 share part of the space, thereby effectively reducing the volume of the floor brush 10.

[0055] It can be understood that, as the cleaning liquid in the clean water tank 220 cannot maintain a fixed shape, and the volume of the cleaning liquid will gradually decrease as cleaning work progresses, if the clean water tank 220 rotates with the roller brush 211, the cleaning liquid will shake greatly inside the clean water tank 220, thus rendering the floor brush 10 unstable during use. In addition, compared to driving only the roller brush 211 itself to rotate, driving the roller brush 211 and the clean water tank 220 to rotate together needs more energy consumption, thereby increasing ineffective power consumption of the floor brush 10.

[0056] Therefore, in the floor brush 10 of the embodiment of the present application, the roller brush 211 is rotatably arranged relative to the floor brush body 100, while the clean water tank 220 is statically arranged relative to the floor brush body 100. Specifically, the roller brush 211 can comprise a cylinder 2111, and a driving connecting part 2112, which are connected to each other. The clean water tank 220 can comprise the water tank body 221, and the first connecting part 222 and the second connecting part 223 which are connected to two ends of the water tank body 221. The water tank body 221 is used to contain the cleaning liquid. The shape of the water tank body 221 matches that of the cylinder 2111, so as to increase the capacity of the clean water tank 220. The second connecting part 223 is statically connected to the floor brush body 100. In other words, the second connecting part 223 can be fixedly connected or removably connected to the floor brush body 100, as long as the second connecting part 223 is statically arranged relative to the floor brush body 100. The driving connecting part 2112 is configured to be connected to a driving assembly arranged at the floor brush body 100 and thus drive the roller brush 211 to rotate by means of the driving assembly, and the driving connecting part 2112 can be rotatably connected to the first connecting part 222 and the second connecting part 223, thereby increasing the stability of the roller brush 211 during rotation. Thus, the roller brush 211 can be rotatably arranged relative to the clean water tank 220, so that when the floor brush 10 is in operation, the roller brush 211 rotates, but the clean water tank 220 will not rotate with the roller brush 211.

[0057] The floor brush 10 provided by the embodiment of the present application comprises the floor brush body 100 and the cleaning part 200. The cleaning part 200 comprises the roller brush assembly 210 and the clean water tank 220. The roller brush assembly 210 comprises the roller brush 211. The roller brush 211 comprises the cylinder 2111 and the driving connecting part 2112. The clean water tank 220 comprises the water tank body 221, the first connecting part 222, and the second connecting part 223. By providing the floor brush body 100 for mounting the cleaning part 200 and other parts, by providing the cylinder 2111 for rolling contact with a surface to be cleaned so as to clean the surface to be cleaned, by providing the driving connecting part 2112 for being rotatably connected to the floor brush body 100 so that the roller brush 211 is rotatably arranged relative to the floor brush body 100, by providing the water tank body 221 for accommodating a cleaning liquid, by providing the second connecting part 223 for being statically connected with the floor brush body 100, and by providing the first connecting part 222 for being rotatably connected to the driving connecting part 2112, the clean water tank 220 is arranged statically relative to the floor brush body 100, and as the roller brush 211 is rotatably arranged relative to the clean water tank 220, the clean water tank 220 is prevented from rotating with the roller brush 211. Thus, with the floor brush 10 provided by the embodiment of the present application, as the clean water tank 220 is integrated inside the roller brush 221, the volume of the floor brush 10 can be effectively reduced, and the clean water tank 220 does not rotate with the roller brush 221, thereby increasing the floor brush 10's stability during use and reducing the floor brush 10's power consumption.

[0058] In reference to Figs. 3 to 6, in a possible mode of realization, the roller brush assembly 210 further comprises a handle member 212, the second connecting part 223 being fixedly connected to the handle member 212, the handle member 212 being removably connected to the floor brush body 100.

[0059] Thus, the second connecting part 223 can be removably connected to the floor brush body 100 by means of the handle member 212, so that the second connecting part 223 is statically connected to the floor brush body 100, and thus the clean water tank 220 is statically arranged relative to the floor brush body 100, thereby preventing the clean water tank 220 from rotating with the roller brush 211.

[0060] In reference to Figs. 5 to 7 and 10, in some modes of realization, the roller brush assembly 210 further comprises a threaded fastener 213, the handle member 212 has a through hole 2121, and the second connecting part 223 has a threaded connecting hole 2231. The through hole 2121 and the threaded connecting hole 2231 both extend along an axial direction of the cylinder 2111. The threaded fastener 213 passes through the through hole 2121 to threadedly connect to the threaded connecting hole 2231.

[0061] Thus, the second connecting part 223 can be fixedly connected to the handle member 212 by means of the threaded fastener 213, so that the clean water tank 220 is fixedly connected to the handle member 212, thereby arranging the clean water tank 220 statically relative to the floor brush body 100.

[0062] In addition, as the clean water tank 220 is fixedly connected to the handle member 212 by means of threaded connection, the clean water tank 220 and the roller brush assembly 210 can form the cleaning part 200. With the handle member 212 removably connected to the floor brush body 100, when needed, the handle member 212 can be removed from the floor brush body 100, so as to remove the cleaning part 200 as a whole from the floor brush body 100.

[0063] In reference to Figs. 3, 5, 6, 7, and 9, in order to increase the stability of the roller brush 211 during rotation, in a possible mode of realization, the roller brush assembly 210 further comprises a driven rotating unit 214. The driven rotating unit 214 is arranged at a second end of the cylinder 2111. The cylinder 2111 is rotatably connected to the second connecting part 223 by means of the driven rotating unit 214.

[0064] Thus, the first end of the cylinder 2111 can be rotatably connected to the floor brush body 100 and the first connecting part 222 at the same time by means of the driving connecting part 2112, and the second end of the cylinder 2111 can be rotatably connected to the second connecting part 223 by means of the driven rotating unit 214, so that two ends of the cylinder 2111 can have rotating support, thereby increasing the stability of the cylinder 2111 during rotation.

[0065] In reference to Figs. 3 and 7, in a possible mode of realization, the driven rotating unit 214 comprises a first bearing member 2141. The first bearing member 2141 is located between the second connecting part 223 and the cylinder 2111. The first bearing member 2141 is fixedly connected to one of the second connecting part 223 and the cylinder 2111, he other of the second connecting part 223 and the cylinder 2111 is rotatably connected to the first bearing member 2141.

[0066] For example, the first bearing member 2141 is fixedly connected to the second connecting part 223, and the cylinder 2111 is rotatably connected to the first bearing member 2141. Alternatively, 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 part 223. Thus, by providing the first bearing member 2141 between the second connecting part 223 and the cylinder 2111, the first bearing member 2141 supports the second end of the cylinder 2111, thereby increasing the stability of the cylinder 2111 during rotation.

[0067] In reference to Figs. 3, 7, and 11, in some modes of realization, the driven rotating unit 214 further comprises an end lid 2142. The second end of the cylinder 2111 is arranged to be open. The end lid 2142 covers the second end of the cylinder 2111.

[0068] The end lid 2142 comprises a blocking part 2142a. The second connecting part 223 is inserted in the blocking part 2142a. The first bearing member 2141 is located between the blocking part 2142a and the second connecting part 223. The blocking part 2142a is interference fit with the first bearing member 2141. The first bearing member 2141 is rotatably connected to the second connecting part 223. The blocking part 2142a is fixedly connected to the cylinder 2111.

[0069] Thus, by sleeving the blocking part 2142a onto the first bearing, and interference fitting the blocking part 2142a with the first bearing member 2141, the first bearing member 2141 and the cylinder 2111 are fixedly connected by means of the blocking part 2142a, so as to fixedly connect the first bearing member 2141 to the cylinder 2111, and so as to rotatably connect the first bearing member 2141 to the second connecting part 223, thereby rotatably connecting the second end of the cylinder 2111 to the second connecting part 223 by means of the end lid 2142 and the first bearing member 2141.

[0070] In reference to Figs. 3, 7, and 11, in a possible mode of realization, the driven rotating unit 214 further comprises an elastic ring 2143. The blocking part 2142a has a ring-shaped groove 2142b. The elastic ring 2143 is sleeved onto the ring-shaped groove 2142b, and the elastic ring 2143 abuts elastically between the cylinder 2111 and the blocking part 2142a.

[0071] Thus, with the elastic ring 2143 sleeved on the blocking part 2142a, as the elastic ring 2143 abuts elastically between the blocking part 2142a and the cylinder 2111, the elastic ring 2143 can fill the gap between the blocking part 2142a and the cylinder 2111, so that the blocking part 2142a is fixedly connected to the cylinder 2111 by means of the elastic ring 2143, thereby the cylinder 2111 drives the end lid 2142 to rotate in a synchronized way relative to the second connecting part 223.

[0072] In reference to Figs. 3, 7, and 11, in some embodiments, the end lid 2142 further comprises a limiting part 2142c. The limiting part 2142c is connected to an end of the blocking part 2142a away from the first connecting part 222. The limiting part 2142c abuts against an end surface of the cylinder 2111.

[0073] Thus, when the end lid 2142 is assembled to the cylinder 2111, the blocking part 2142a can be inserted into the cylinder 2111, and the blocking part 2142a can be fixedly connected to the cylinder 2111 by means of the elastic ring 2143, while the limiting part 2142c can abut against an end surface of the second end of the cylinder 2111, thereby limiting the insertion depth of the blocking part 2142a, and thus increasing assembly precision and assembly efficiency of the end lid 2142.

[0074] In reference to Figs. 8 and 9, in some embodiments, the roller brush assembly 210 further comprises a second bearing member 215. The first connecting part 222 has a rotation cavity 2221. The driving connecting part 2112 comprises a rotary shaft 2112a. The second bearing member 215 is insertion connected to the rotation cavity 2221. The rotary shaft 2112a is rotatably connected to the second bearing member 215.

[0075] Thus, by providing the rotation cavity 2221 at the first connecting part 222 for the rotary shaft 2112a to be inserted into, the driving connecting part 2112 is rotatably connected to the first connecting part 222. By providing the second bearing member 215 between the rotation cavity 2221 and the rotary shaft 2112a, the rotary shaft 2112a can be supported by the second bearing member 215, so that the rotation of the first end of the cylinder 2111 is more stable and smoother.

[0076] The first end and second end of the cylinder 2111 both have rotation support and are more balanced during rotation. The roller brush 211 cannot be easily worn, thereby allowing the service life of the floor brush 10 to be prolonged.

[0077] In reference to Figs. 6 and 9, in a possible mode of realization, the water tank body 221 defines a water containing chamber 2211. The rotation cavity 2221 is located in the water containing chamber 2211.

[0078] With such arrangement, the water containing chamber 2211 can be used to contain a cleaning liquid, and with the rotation cavity 2221 and the water containing chamber 2211 being arranged from inside to outside along the peripheral direction of the cylinder 2111, the first connecting part 222 can be prevented from protruding out of the water tank body 221, so that after the clean water tank 220 and the roller brush 211 are assembled together, the size of the cleaning part 200 along the axial direction of the roller brush 211 is relatively small, and the structure of the floor brush 10 is more compact.

[0079] In reference to Fig. 10, in some modes of realization, the second connecting part 223 further has a water flow channel 2232. The water flow channel 2232 puts the inside and outside of the water tank body 221 in communication.

[0080] Thus, when the clean water tank 220 needs to be replenished with the cleaning liquid, the cleaning liquid can be injected into the clean water tank 220 via the water flow channel 2232, or, when the floor brush 10 is in operation and the cleaning liquid needs to sprayed towards the roller brush 211 or a surface to be cleaned from the clean water tank 220, the cleaning liquid can flow out via the water flow channel 2232.

[0081] In a possible mode of realization, the driving connecting part 2112 is located in the cylinder 2111. That is, the driving connecting part 2112 is located inside the first end of the cylinder 2111. Compared to arranging the driving connecting part 2112 outside the cylinder 2111, arranging the driving connecting part 2112 inside the cylinder 2111 can reduce the size of the cleaning part 200 along the axial direction of the cylinder 2111, thereby reducing the volume of the floor brush 10.

[0082] 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 2111. Such arrangement can prevent friction between the outer side wall of the water tank body 221 and the inner side wall of the cylinder 2111 when the cylinder 2111 rotates. Thus, the water tank body 221 can be prevented from obstructing the rotation of the cylinder 2111.

[0083] In a possible mode of realization, there are two cleaning parts 200. The two cleaning parts 200 are arranged at intervals along the advancing direction of the floor brush 10.

[0084] It should be understood that when two cleaning parts 200 are arranged at intervals along the advancing direction of the floor brush 10, the roller brush 211 of one cleaning part 200 can be used for dry suction, while the roller brush 211 of the other cleaning part 200 can be used for wet mopping. Alternatively, the roller brushes 211 of both cleaning parts 200 can be used for wet mopping. Embodiments of the present application do not limit this. With such arrangement, the floor brush 10's cleaning effect and cleaning efficiency can be increased, and as the floor brush 10 has two clean water tanks 220, the volume of the cleaning liquid of the floor brush 10 can be increased, thereby improving the lasting capacity of the floor brush 10 during wet mopping.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some or all of the technical features can be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to depart from the scope of the technical solutions of the embodiments of the present application.
