Technical Field

[0003] The present application relates to the technical field of cleaning equipment, and in particular to a floor brush and cleaning equipment. Background Art

[0004] The roller brush of the cleaning equipment will wear out after being used for a period of time. If the water squeezing scraper cannot move, the water squeezing effect will deteriorate and the residual water in the ground cleaning area will increase.

[0005] In related technologies, the squeezing blade is often located between the diverter and the main brush body. Directly controlling the movement of the squeezing blade complicates and hinders installation and fixation. Furthermore, excessive pressure between the squeezing blade and the roller brush can accelerate brush wear, while insufficient pressure can increase residual water on the floor. If the position adjustment mechanism directly interferes with the squeezing blade, controlling its movement becomes difficult. Using a drive mechanism to control the movement of the squeezing blade increases costs.

[0106] The following describes in detail embodiments of the present application, and the embodiments described with reference to the accompanying drawings are exemplary.

[0107] The following describes a floor brush 100 according to an embodiment of the present application with reference to Figures 1 to 21. The floor brush 100 includes a floor brush body 10 and a roller brush assembly 20. The floor brush body 10 protects its internal structure and constitutes the external structure of the floor brush 100. The roller brush assembly 20 cleans the dirt by rolling on the cleaning surface to pick up dirt attached during movement.

[0108] According to some embodiments of the present application, referring to Figures 1-21, especially the floor brush 100 described with reference to Figures 1-9, the diverter 311 can drive the water-squeezing scraper 314 to rotate slightly toward the side of the roller brush assembly 20 as the floor brush 100 wears, so that the water-squeezing scraper 314 always maintains contact with the roller brush assembly 20.

[0109] Specifically, referring to Figures 1-21, and especially Figures 1-9, the floor brush 100 can ensure that the water-squeezing scraper 314 in the floor brush 100, which is used to squeeze water from the roller brush assembly 20, can always maintain contact with the roller brush assembly 20, thereby avoiding the increase of residual water on the cleaning surface due to wear of the roller brush assembly 20. Here, the floor brush 100 can adopt the corresponding structure and shape of the sewage tank equipped with various types of cleaning equipment 200, such as handheld vacuum cleaners, horizontal vacuum cleaners, upright vacuum cleaners, and barrel vacuum cleaners, so as to provide suction to suck in dust and garbage. This embodiment of the present application is not limited to this.

[0110] According to some embodiments of the present application, as shown in Figures 1 to 6, a floor brush 100 includes a floor brush body 10, a roller brush assembly 20, and a floating scraper assembly 30. The floating scraper assembly 30 is used to squeeze the roller brush assembly 20 during cleaning to prevent dirty water on the roller brush assembly 20 from remaining on the cleaning surface.

[0111] Specifically, the roller brush assembly 20 is rotatably mounted on the floor brush body 10. The floating scraper assembly 30 includes a water-squeezing scraper 314 and a diverter 313. The diverter 313 is rotatably mounted on the floor brush 100. The water-squeezing scraper 314 is fixedly connected to the diverter 313. When the roller brush assembly 20 rotates, the water-squeezing scraper 314 scrapes off solid dirt on the surface of the roller brush assembly 20 and squeezes out dirty water from the roller brush assembly 20. The water-squeezing scraper 314 is fixedly connected to the diverter 313. When the roller brush assembly 20 rotates, the water-squeezing scraper 314 scrapes off solid dirt on the surface of the roller brush assembly 20 and squeezes out dirty water from the roller brush assembly 20.

[0112] The roller brush assembly 20 is rotatably mounted on the floor brush body 10, facilitating both cleaning and smooth movement across the surface being cleaned. The diverter 313 evenly diverts clean water from the cleaning device 200 to the roller brush assembly 20, facilitating its removal of dirt from the cleaning surface. The water-squeezing scraper 314 effectively scrapes away solid dirt from the surface of the roller brush assembly 20 and squeezes out wastewater from within the roller brush assembly 20 as it rotates.

[0113] In addition, since the diverter 313 is rotatably arranged on the floor brush body 10, even if the roller brush assembly 20 gradually wears and becomes thinner with continuous use or when a roller brush assembly 20 of a different size is replaced, the diverter 313 can rotate toward the side of the roller brush assembly 20 so that the water-squeezing scraper 314 and the roller brush assembly 20 always maintain contact, thereby ensuring that the water-squeezing scraper 314 can normally perform the function of scraping solid stains on the surface of the roller brush assembly 20 and squeezing out sewage in the roller brush assembly 20 when the roller brush assembly 20 of different specifications or under continuous wear conditions rotates, thereby avoiding the problem of insufficient cleaning of the cleaning surface and increased residual water on the ground due to insufficient contact between the floating scraper assembly 30 and the surface of the roller brush assembly 20.

[0114] For example, in one embodiment, the diverter 313 is rotatably mounted on the floor brush 100, and the user cannot remove the floating scraper assembly 30 from the main body of the floor brush 100, thereby enhancing the structural stability of the diverter 313. In another embodiment, the diverter 313 is mounted on the roller brush cover 12 of the floor brush body 10. The roller brush cover 12 and the floor brush body 10 are detachably connected via a switch assembly. When the roller brush cover 12 is removed from the floor brush body 10, the diverter 313 is also removed, thereby facilitating cleaning of the diverter 313.

[0115] Therefore, by setting up the floating scraper assembly 30, the diverter 313 can drive the water-squeezing scraper 314 to rotate slightly toward the side of the roller brush assembly 20 as the floor brush 100 wears, so that the water-squeezing scraper 314 always maintains contact with the roller brush assembly 20, thereby avoiding the problem of increased residual water on the cleaning surface due to the wear of the floor brush 100.

[0116] According to some optional embodiments of the present application, as shown in Figures 2, 3, and 6-9, the diverter 313 is provided with a rotating shaft 311, and the floating scraper bar assembly 30 is rotatably connected to the floor brush body 10 via the rotating shaft 311. The floating scraper bar assembly 30 also includes an elastic member 32, which is located between the diverter 313 and the floor brush body 10 to float and support the floating scraper bar assembly 30, so that the water squeezing scraper bar 314 in the floating scraper bar assembly 30 always maintains contact with the roller brush assembly 20.

[0117] Specifically, because the rotating shaft 311 on the diverter 313 is rotatably connected to the floor brush body 10, the floating scraper bar assembly 30 is also rotatably connected to the floor brush body 10. The elastic member 32 abuts between the diverter 313 and the floor brush body 10, automatically and continuously applying an elastic force to the floating scraper bar assembly 30 to drive the floating scraper bar assembly 30 to rotate toward the roller brush assembly 20. This ensures that the water-squeezing scraper bar 314 in the floating scraper bar assembly 30 maintains contact with the roller brush assembly 20, thereby enhancing the scientific nature of the water-squeezing scraper bar 314 maintaining contact with the roller brush assembly 20.

[0118] According to some optional embodiments of the present application, in combination with Figures 2, 3, 6-9, the diverter 313 is provided with a rotating shaft 311 at both ends along the length direction, and the rotating shaft 311 is rotatably provided on the floor brush body 10. The rear end of the diverter 313 is connected to a driving device (not shown), which drives the diverter 313 to rotate, thereby maintaining the contact between the water-squeezing scraper 314 and the roller brush assembly 20.

[0119] Specifically, since the rotating shaft 311 on the diverter 313 is rotatably connected to the floor brush body 10, the floating scraper bar assembly 30 is also rotatably connected to the floor brush body 10. A driving device is provided on the side of the diverter 313 facing away from the roller brush assembly 20. This allows the diverter 313 to exert an elastic force on the floating scraper bar assembly 30 according to a control signal, driving the floating scraper bar assembly 30 to rotate toward the roller brush assembly 20, thereby maintaining contact between the water-squeezing scraper bar 314 and the roller brush assembly 20. This improves the controllability and intelligence of the contact between the water-squeezing scraper bar 314 and the roller brush assembly 20.

[0120] Specifically, as shown in Figures 6-9 , the squeezing and scraping strip 314 is fixedly mounted on the lower end surface of the diverter 313, the rotating shaft 311 is disposed at the upper end of the diverter 313, and the elastic member 32 is located between the axis of the rotating shaft 311 and the squeezing and scraping strip 314 to maintain the squeezing force of the squeezing and scraping strip 314 toward the roller brush assembly 20. The rotating shaft 311 and the squeezing and scraping strip 314 are located at the upper and lower end surfaces of the diverter 313, respectively. This allows the squeezing and scraping strip 314 to be farther away from the rotating shaft 311, thereby allowing the squeezing and scraping strip 314 to achieve a larger rotation range and torque, thereby improving the squeezing and scraping effect of the squeezing and scraping strip 314.

[0121] Furthermore, as shown in Figures 2 and 5, the floor brush body 10 includes a floor brush base 11 and a roller brush cover 12. The roller brush cover 12 is detachably mounted on the floor brush base 11. Compared with an integrated floor brush body 10, this makes it easier to disassemble and replace the roller brush cover 12 and the floor brush base 11, thereby reducing overall maintenance costs.

[0122] Specifically, the diverter 313 is rotatably mounted on the floor brush base 11, or the diverter 313 is rotatably mounted on the roller brush cover 12. For example, if the diverter 313 is rotatably mounted on the roller brush cover 12, when the diverter 313 needs to be replaced or repaired, it can be done by simply removing the roller brush cover 12 from the floor brush body 10, thereby improving the convenience of installing and removing the diverter 313.

[0123] Specifically, as shown in Figures 2 and 5 , the floor brush base 11 is provided with a mounting groove 13 adjacent to the roller brush assembly 20. A shaft mounting hole is provided at each end of the mounting groove 13. The floating scraper bar assembly 30 is disposed within the mounting groove 13, and the shaft 311 of the diverter 313 is engaged with the shaft mounting hole. The mounting groove 13 provides a space for the floating scraper bar assembly 30 to be mounted and fixed, and the shaft 311 on the diverter 313 is engaged with the shaft mounting hole within the mounting groove 13, thereby improving the rationality of the structural layout of the floor brush 100.

[0124] Furthermore, as shown in Figures 6-9 , the rear end surface of the diverter 313 is provided with a water inlet hole 3135 and a positioning portion 3136. The water inlet hole 3135 is connected to the clean water tank via a water pipeline, and the elastic member 32 is mounted on the positioning portion 3136. The rear end surface of the diverter 313 is provided with a water inlet hole 3135 that is connected to the clean water tank. This allows clean water in the clean water tank to be directed to the diverter 313 via the water pipeline, thereby achieving the effect of the diverter 313 continuously spraying clean water onto the roller brush assembly 20. Furthermore, the elastic member 32 is mounted on the positioning portion 3136 on the rear end surface of the diverter 313. This improves the positional stability of the elastic member 32, thereby further ensuring that the water-squeezing scraper 314 in the floating scraper assembly 30 maintains contact with the roller brush assembly 20.

[0125] Specifically, as shown in Figure 6, the water-squeezing scraper 314 includes a water-squeezing end 3143 that contacts the roller brush assembly 20, and a sealing groove 3141 is provided on the side of the water-squeezing end 3143 that contacts the mounting groove 13. A sealing member 3142 is provided in the sealing groove 3141. The sealing member 3142 is deformed during the rotation of the water-squeezing scraper 314 to prevent dirt from entering the mounting groove 13 through the gap between the water-squeezing scraper 314 and the mounting groove 13.

[0126] According to other optional embodiments of the present application, an elastic member 32 is provided between the floating scraper bar assembly 30 and the floor brush body 10. The elastic member 32 elastically abuts between the floor brush body 10 and the floating scraper bar assembly 30 so that the water-squeezing scraper 314 always maintains contact with the roller brush assembly 20. There are multiple elastic members 32, and the multiple elastic members 32 are spaced apart in the second direction.

[0127] In detail, the elastic member 32 elastically abuts between the floor brush body 10 and the water squeezing scraper bar 314 assembly, so that the elastic force of the elastic member 32 can push the contact portion of the water squeezing scraper bar 314 and the roller brush assembly 20 to rotate toward the side of the roller brush assembly 20. Therefore, even if the roller brush assembly 20 gradually wears and becomes thinner with continuous use or when the roller brush assembly 20 of a different size is replaced, the water squeezing scraper bar 314 can always maintain contact with the roller brush assembly 20, thereby ensuring that the water squeezing scraper bar 314 can normally realize the function of scraping solid stains on the surface of the roller brush assembly 20 and squeezing out sewage in the roller brush assembly 20 when the roller brush assembly 20 rotates, thereby avoiding the problem of insufficient cleaning of the cleaning surface and increased residual water on the ground due to insufficient contact between the floating scraper bar assembly 30 and the surface of the roller brush assembly 20.

[0128] Furthermore, compared to directly controlling the movement of the floating scraper assembly, which increases the difficulty of installing and securing the floating scraper assembly, and excessive squeezing force between the floating scraper assembly and the roller brush can lead to accelerated wear of the roller brush, while insufficient squeezing force between the floating scraper assembly and the roller brush can lead to increased residual water on the cleaning surface, the embodiment of this solution has a simple structure, and the squeezing force of the floating scraper assembly 30 on the roller brush assembly 20 is more easily controlled. Compared to directly integrating the position adjustment mechanism with the floating scraper assembly, which increases the difficulty of controlling the movement of the floating scraper assembly and causes problems such as poor roller brush movement and accelerated roller brush wear, the embodiment of this solution only uses a portion of the squeezing scraper 314 to adaptively contact the roller brush assembly 20. Furthermore, the squeezing force of the floating scraper assembly 30 on the roller brush assembly 20 is easier to control and less excessive, thereby balancing the smooth movement of the roller brush assembly 20 and the squeezing ability of the floating scraper assembly 30. Compared with adopting a driving mechanism to control and adjust the movement of the floating scraper assembly, which may lead to the problem of increased cost, the embodiment of this solution has a simple structure and low cost.

[0129] Furthermore, a plurality of elastic members 32 are provided, and the plurality of elastic members 32 are spaced apart in the second direction. The plurality of elastic members 32 are spaced apart along the axial direction of the rotating shaft 311. Increasing the number of elastic members 32 increases the elastic force exerted on the floating scraper assembly 30 by the elastic members 32 and the path of action of the elastic force, thereby improving the uniformity and magnitude of the force exerted on the floating scraper assembly 30, thereby improving the rotational stability of the floating scraper assembly 30 and the stability of the contact between the squeezing scraper bar 314 and the roller brush assembly 20.

[0130] Specifically, as shown in FIG. 6 , the diverter 313 is provided with a rotating shaft 311 , which is rotatably provided on the floor brush body 10 , and the axis of the elastic member 32 is non-collinear with the axis of the rotating shaft 311 .

[0131] Specifically, the diverter 313 is provided with a rotating shaft 311 along the axial direction of the roller brush assembly 20. The floating scraper assembly 30 is rotatably connected to the floor brush body 10 via the rotating shaft 311, thereby ensuring that the water-squeezing scraper bar 314 maintains constant contact with the roller brush assembly 20. The elastic member 32 abuts between the floor brush body 10 and the water-squeezing scraper bar 314, and the line connecting the two elastic abutment points is the axis of the elastic member 32. The axis of the elastic member 32 is non-collinear with the axis of the rotating shaft 311. This ensures that the elastic member 32 always has an elastic force component that pushes the water-squeezing scraper bar 314 toward the roller brush assembly 20, thereby ensuring that the water-squeezing scraper bar 314 always has an external force to rotate toward the roller brush assembly 20, thereby maintaining constant contact with the roller brush assembly 20. For example, the rotating shaft 311 can be a separate component or can be integrally formed with the water-squeezing scraper bar 314.

[0132] Specifically, as shown in FIG6 , the axis of the elastic member 32 extends in a first direction, and the axis of the rotating shaft 311 is spaced apart in a second direction, with the first and second directions being perpendicular to each other. Furthermore, the vertical plane on which the axis of the elastic member 32 lies is perpendicular to the vertical plane on which the axis of the rotating shaft 311 lies. This prevents the elastic member 32 from losing any ineffective force component during the application of the elastic force by the floating scraper assembly 30, which could result in insufficient extrusion force. This ensures that the water-squeezing scraper 314 maintains contact with the roller brush assembly 20.

[0133] Specifically, as shown in Figures 6 to 8, a wiper tooth 312 is provided at one end of the water-squeezing scraper strip 314 in the third direction, and the wiper tooth 312 extends toward the roller brush assembly 20. The rotating shaft 311 is located at the other end of the water-squeezing scraper strip 314 in the third direction, and the elastic member 32 is located between the rotating shaft 311 and the wiper tooth 312, wherein the third direction is perpendicular to the second direction.

[0134] For example, the wiper teeth 312 and the rotating shaft 311 are located at opposite ends of the wiper bar 314 along the third direction. This allows the wiper bar 314 to cut and remove hair from the roller brush assembly 20, effectively preventing hair from becoming entangled in the roller brush assembly 20 and thereby improving the cleaning performance of the floor brush 100. Furthermore, the second direction is perpendicular to the third direction, facilitating the rotation of the wiper bar 314 about the rotating shaft 311, ensuring that the wiper bar 314 and the roller brush assembly 20 maintain contact. Furthermore, the elastic member 32 is located between the rotating shaft 311 and the wiper teeth 312, further away from the axis of the rotating shaft 311. This increases the torque applied by the elastic member 32 to push the wiper bar 314, thereby improving the smoothness of the rotation of the wiper bar 314.

[0135] Specifically, in the third direction of the floating scraper assembly 30, the elastic member 32 is located between the squeezing scraper bar 314 and the rotating shaft 311. The third direction is perpendicular to the second direction. The elastic member 32 is located between the squeezing scraper bar 314 and the rotating shaft 311 along the third direction of the floating scraper assembly 30. This ensures that the elastic force exerted by the elastic member 32 on the floating scraper assembly 30 forms a certain distance from the rotating shaft 311, generating a torque. This facilitates the elastic member 32 pushing the squeezing scraper bar 314 to rotate as the diverter 313 rotates.

[0136] Furthermore, the second direction is perpendicular to the third direction, which facilitates the rotation of the squeezing scraper bar 314 about the rotating shaft 311, thereby ensuring that the squeezing scraper bar 314 and the roller brush assembly 20 maintain contact. Furthermore, the elastic member 32 is located between the rotating shaft 311 and the wiper teeth 312. This allows the elastic member 32 to be farther away from the axis of the rotating shaft 311, thereby increasing the torque applied by the elastic member 32 to push the squeezing scraper bar 314, thereby improving the smoothness of the rotation of the squeezing scraper bar 314.

[0137] Furthermore, in combination with Figures 6 to 8, the rotating shaft 311 is arranged on the diverter 313, the elastic member 32 is abutted between the diverter 313 and the floor brush body 10, the water-squeezing scraper 314 is arranged on one side of the diverter 313 in the third direction, and the wiper teeth 312 are arranged at one end of the water-squeezing scraper 314 in the third direction away from the diverter 313.

[0138] The diverter 313 can evenly divert clean water from the cleaning device 200 to the roller brush assembly 20, facilitating the roller brush assembly 20 to clean dirt from the cleaning surface. In this embodiment, the water-squeezing scraper 314 is made of metal. The water-squeezing scraper 314 and the diverter 313 are fixedly connected by multiple fasteners (e.g., screws). The water-squeezing scraper 314 and the diverter 313 can be flexibly and detachably connected via the fasteners. The diverter 313 is formed by ultrasonically welding two parts along a first direction.

[0139] Furthermore, the water-squeezing scraper bar 314 is located on one side of the diverter member 313 along the third direction. This facilitates the water-squeezing scraper bar 314 to rotate toward the roller brush assembly 20 as the rotating shaft 311 on the diverter member 313 rotates. This ensures that the water-squeezing scraper bar 314 can maintain smooth and effortless contact with the surface of the roller brush assembly 20, thereby preventing the problem of excess water on the cleaning surface. Furthermore, the water-squeezing scraper teeth 312 are located on the end of the water-squeezing scraper bar 314 facing away from the diverter member 313 in the third direction. This allows the water-squeezing scraper teeth 312 to be closer to the roller brush assembly 20, thereby ensuring the cleaning performance of the roller brush assembly 20.

[0140] Specifically, in combination with Figures 6 and 7, the diverter 313 is provided with an arc-shaped water-dividing surface 3131 on the side facing the roller brush assembly 20, the scraper teeth 312 are located at one end of the arc-shaped water-dividing surface 3131 in the third direction, and the diverter 313 is provided with a smoothing portion 3134 at the other end corresponding to the arc-shaped water-dividing surface 3131 in the third direction. The smoothing portion 3134 is in contact with the roller brush assembly 20 to evenly spread the water on the surface of the roller brush assembly 20.

[0141] Among them, an arc-shaped water dividing surface 3131 is formed on the side of the diverter 313 facing the roller brush assembly 20, which fits the outer surface of the roller brush assembly 20, so that the clean water flowing out of the diverter 313 can flow along the contour of the arc-shaped water dividing surface 3131 to the roller brush assembly 20, thereby increasing the coverage and uniformity of the clean water infiltration of the roller brush assembly 20, thereby improving the cleaning effect of the roller brush assembly 20.

[0142] Furthermore, a smoothing portion 3134 is provided at the other end of the diverter 313, corresponding to the arcuate water-dividing surface 3131 in the third direction. This smoothing portion 3134 is in line or surface contact with the roller brush assembly 20 along the axial direction. This allows the diverter 313 to evenly smooth the clean water remaining on the outer surface of the roller brush assembly 20, thereby improving the cleaning effect of the roller brush assembly 20. Furthermore, a flow channel is provided within the diverter 313. Clean water flowing in through the water inlet 3135 is diverted through the flow channel and then flows out through the outlet on the arcuate water-dividing surface 3131, which faces one side of the roller brush assembly 20.

[0143] In detail, an arc-shaped water dividing surface 3131 is provided on the side of the diverter 313 facing the roller brush assembly 20 in the first direction, the rotating shaft 311 and the elastic member 32 are both provided on the side of the arc-shaped water dividing surface 3131 facing away from the roller brush assembly 20 in the first direction, and the water squeezing scraper 314 is provided at one end of the arc-shaped water dividing surface 3131 in the third direction.

[0144] Among them, an arc-shaped water dividing surface 3131 that fits with the outer surface of the roller brush assembly 20 is formed on the side of the diverter 313 facing the roller brush assembly 20 in the first direction, so that the clean water flowing out of the diverter 313 can flow along the contour of the arc-shaped water dividing surface 3131 to the roller brush assembly 20, thereby increasing the coverage and uniformity of the clean water infiltration of the roller brush assembly 20, thereby improving the cleaning effect of the roller brush assembly 20.

[0145] Furthermore, the rotating shaft 311 and the elastic member 32 are both positioned on the side of the arc-shaped water dividing surface 3131 facing away from the roller brush assembly 20 in the first direction. This prevents the rotating shaft 311 and the elastic member 32 from interfering with the contact between the diverter member 313 and the outer surface of the roller brush assembly 20, thereby improving the rationality of their arrangement. The water-squeezing scraper 314 is positioned at one end of the arc-shaped water dividing surface 3131 in the third direction. This facilitates the water-squeezing scraper 314 to pre-scrape dirt and squeeze water from the roller brush assembly 20, thereby achieving a circular cleaning effect for the roller brush assembly 20.

[0146] According to some optional embodiments of the present application, one of the diverter 313 and the water-squeezing scraper 314 is provided with a connecting protrusion, and the other is provided with a connecting hole, and the connecting protrusion and the connecting hole are detachably connected and fixed. For example, the connecting protrusion on the diverter 313 and the connecting hole in the water-squeezing scraper 314 are snap-fitted and fixed. Compared with other connection methods, this connection method is simpler and more convenient, and is easy to disassemble and replace.

[0147] According to some optional embodiments of the present application, the floor brush body 10 includes a shell portion and a cover portion, the cover portion is detachably mounted on the shell portion, and the diverter 313 is rotatably mounted on the shell portion. Specifically, the cover portion and the shell portion are detachably mounted on each other, which facilitates user replacement and repair of structural components inside the floor brush body 10. The diverter 313 is rotatably mounted on the shell portion, which provides a carrier for mounting and fixing the diverter 313, thereby achieving the effect of rotating the diverter 313 toward the side of the roller brush assembly 20 so that the water-squeezing scraper 314 always maintains contact with the roller brush assembly 20.

[0148] According to some optional embodiments of the present application, the diverter 313 is rotatably mounted on the cover. Specifically, the cover and housing are detachably mounted, making it easier for users to replace and repair components within the floor brush body 10. The diverter 313 is rotatably mounted on the cover, providing a mounting support for the diverter 313. This allows the diverter 313 to rotate toward the roller brush assembly 20, ensuring that the water-squeezing blade 314 maintains contact with the roller brush assembly 20.

[0149] Further, in combination with Figures 6 and 7, the diverter 313 includes a main board portion 3132 and a folding plate portion 3133, the arc-shaped water dividing surface 3131 is arranged on the side of the main board portion 3132 toward the roller brush assembly 20, the folding plate portion 3133 is arranged at the other end of the main board portion 3132 in the third direction and is bent and extended relative to the main board portion 3132 toward the side away from the roller brush assembly 20, and the smoothing portion 3134 is located between the folding plate portion 3133 and the main board portion 3132.

[0150] 6 and 7 , the main board portion 3132, the smoothing portion 3134 and the folding plate portion 3133 are connected in sequence, and the folding plate portion 3133 is provided at the other end of the main board portion 3132 in the third direction and is bent and extended relative to the main board portion 3132 toward a side away from the roller brush assembly 20, so that the extension direction of the main board portion 3132 is changed by the folding plate portion 3133, and the smoothing portion 3134 is formed at the bent connection between the main board portion 3132 and the folding plate portion 3133, which can provide a structural carrier for the structure of the smoothing portion 3134 and can also enhance the structural strength of the smoothing portion 3134, thereby improving the design rationality and scientificity of the diverter 313.

[0151] Specifically, the roller brush assembly 20 is located on one side of the diverter 313 in the first direction, and a sealing groove 3141 is provided on the side of the water-squeezing scraper 314 in the first direction away from the roller brush assembly 20. A sealing member 3142 is provided in the sealing groove 3141, and the sealing member 3142 is sealed with the floor brush body 10.

[0152] The water-squeezing scraper 314 is provided with a sealing groove 3141 on one side along the first direction and away from the roller brush assembly 20, which provides a fixed installation position for the seal 3142. When the roller brush assembly 20 located on the first side of the diverter 313 is performing cleaning work, the water-squeezing scraper 314 squeezes and scrapes the sewage carried by the roller brush assembly 20 onto the side of the water-squeezing scraper 314 along the first direction away from the roller brush assembly 20. The seal 3142 is provided on this side and seals with the floor brush body 10. This prevents the problem of some dirt from entering the interior of the floor brush 100 through the gap between the water-squeezing scraper 314 and the floor brush body 10 when the cleaning device 200 is sucking sewage through the sewage suction port.

[0153] In detail, the cleaning process of the cleaning device 200 is introduced below: the diverter 313 sprays clean water to the roller brush assembly 20, the spreading part 3134 spreads the clean water sprayed onto the surface of the roller brush assembly 20, the wet roller brush assembly 20 wipes the ground, and the water-squeezing scraper 314 scrapes the surface of the roller brush assembly 20 after wiping, and the scraped solid stains and sewage are sucked into the sewage tank of the cleaning device 200 through the sewage suction port.

[0154] According to some embodiments of the present application, referring to Figures 10 to 16, the floor brush 100 can selectively lock the roller brush cover 12 and the floor brush body 10 by rotating the operating part 3011, thereby saving the user the effort required for disassembly and assembly, and the assembly form is simple, thereby improving its practicality and convenience.

[0155] Specifically, as shown in Figures 10-16, the floor brush 100 can selectively lock the roller brush cover 12 and the floor brush body 10 by rotating the operating portion 3011, thereby reducing the effort required for disassembly and assembly by the user. Furthermore, the assembly method is simple, thereby improving its practicality and convenience. Here, the floor brush 100 can adopt the corresponding structure and shape of the sewage tank configured for various types of cleaning equipment 200, such as handheld vacuum cleaners, horizontal vacuum cleaners, upright vacuum cleaners, and barrel vacuum cleaners, so as to provide suction to suck in dust and garbage. This embodiment of the application is not limited to this.

[0156] Specifically, a first locking portion 14 is provided on the floor brush body 10 , and a roller brush cover 12 is provided on the front side of the floor brush body 10 , and the roller brush cover 12 is located above the roller brush assembly 20 .

[0157] The floor brush 100 also includes: a locking member 31, the locking member 31 includes an operating part 3011 and a second locking part 3012, the operating part 3011 is rotatably arranged on the upper surface of the roller brush cover 12, and the second locking part 3012 is arranged on the operating part 3011, and the operating part 3011 selectively operates the second locking part 3012 to lock and cooperate with the first locking part 14.

[0158] The first locking portion 14 on the floor brush body 10 and the second locking portion 3012 on the locking member 31 can be locked together to lock the roller brush cover 12 to the floor brush body 10. Furthermore, the locking member 31 includes a manipulation portion 3011 and a second locking portion 3012. The manipulation portion 3011 is rotatably disposed on the upper surface of the roller brush cover 12. This allows a user to manipulate the manipulation portion 3011 on the upper surface of the roller brush cover 12 to cause the second locking portion 3012 to rotate accordingly. As the second locking portion 3012 rotates, the relative position of the second locking portion 3012 and the first locking portion 14 also changes. This allows the locking relationship between the second locking portion 3012 and the first locking portion 14 to be controlled, thereby flexibly meeting the user's needs for disassembly and assembly of the roller brush cover 12. Furthermore, this simple locking assembly method can save the user effort during disassembly and assembly, and can also reduce assembly difficulty.

[0159] Therefore, the first locking part 14 and the second locking part 3012 can be selectively locked by rotating the operating part 3011, thereby saving the user the force applied to disassemble and assemble the roller brush cover 12 from the floor brush body 10, and the assembly form is simple, thereby improving its practicality and convenience.

[0160] According to some optional embodiments of the present application, as shown in Figures 11 and 14 to 16, the first locking portion 14 is provided on the front side of the floor brush body 10, the operating portion 3011 is provided on the rear side of the roller brush cover 12, and the second locking portion 3012 is provided below the operating portion 3011 and corresponds to the first locking portion 14. In detail, the roller brush cover 12 is located on the front side of the floor brush body 10, and the first locking portion 14 and the operating portion 3011 are correspondingly located on the front side of the floor brush body 10 and the rear side of the roller brush cover 12. This helps to shorten the distance between the first locking portion 14 and the second locking portion 3012 below the operating portion 3011, thereby facilitating the operating portion 3011 to manipulate the second locking member 31 to selectively lock with the first locking portion 14.

[0161] Specifically, the operating part 3011 is an operating plate, and an elastic reset member is provided between the operating plate and the roller brush cover 12. The elastic reset member can generate an elastic force when elastically deformed. The elastic reset member is in a compressed state and is provided between the operating plate and the roller brush cover 12. The elastic reset member can provide the operating part 3011 with the elastic locking reset force required when the second locking part 3012 and the first locking part 14 remain in a locked engagement position, thereby ensuring the locking stability between the first locking part 14 and the second locking part 3012. When the user needs to remove the roller brush cover 12, the user overcomes the elastic force and controls the operating part 3011 to rotate in the direction in which the first locking part 14 and the second locking part 3012 are unlocked.

[0162] Furthermore, the elastic return member includes at least one of a torsion spring and a spring. For example, the elastic return member can be a torsion spring. The floor brush body 10 is provided with a rotating shaft mounting hole, the operating portion 3011 is provided with a rotating shaft, and the torsion spring is mounted on the rotating shaft. A torsion spring is a helical spring that can store and release angular energy or statically fix a device by rotating a force arm around the central axis of the spring body. When the torsion spring is mounted on the rotating shaft, when the rotating shaft rotates to an angle at which the first locking portion 14 and the second locking portion 3012 are locked, the torsion spring exerts a rotational return force on the rotating shaft, causing it to move toward the locked position. This allows the second locking portion 3012 to stably remain in the position where it is locked with the first locking portion 14.

[0163] For another example, the elastic return member can be a spring, which abuts between the locking member 31 and the floor brush body 10. When the first locking portion 14 rotates to a position for locking with the second locking portion 3012, the spring is in a compressed state, and the spring still forms a rotational return force on the second locking portion 3012 to make it tend to the locking position, so that the second locking portion 3012 stays stably in the position for locking cooperation with the first locking portion 14.

[0164] According to some optional embodiments of the present application, as shown in Figures 14 to 16, one of the first locking portion 14 and the second locking portion 3012 is a locking groove, and the other is a locking tongue, and the locking groove and the locking tongue are locked together.

[0165] For example, the first locking portion 14 on the floor brush body 10 is configured as a locking groove, and the second locking portion 3012 on the locking member 31 is configured as a locking tongue extending toward one side of the locking groove. When the operating portion 3011 drives the second locking portion 3012 to rotate to the locked position, the locking tongue now penetrates the locking groove and hooks onto the bottom of the upper edge of the locking groove. This locking connection between the locking groove and the locking tongue simplifies the locking structure of the first locking portion 14 and the second locking portion 3012, thereby facilitating processing and manufacturing and reducing economic costs. In addition, the locking tongue can freely translate within a certain range within the locking groove. This allows the locking tongue to have a certain position adjustment margin during the rotation process of locking in the locking groove, thereby increasing the probability that the locking tongue will successfully hook into the locking groove, thereby ensuring the stability of the locking function of the first locking portion 14 and the second locking portion 3012.

[0166] According to some optional embodiments of the present application, in combination with Figures 11, 13 and 14, a first positioning portion 15 is provided on the floor brush body 10, and a second positioning portion 33 is provided on the roller brush cover 12, and the first positioning portion 15 and the second positioning portion 33 are positioned and matched. Specifically, the first positioning portion 15 on the floor brush body 10 and the second positioning portion 33 on the roller brush cover 12 are positioned and matched in the vertical direction, so that the roller brush cover 12 can be provided with a positioning and installation function during the process of being assembled to the floor brush body 10, further limiting the assembly position of the roller brush cover 12, thereby increasing the probability of the roller brush cover 12 being smoothly assembled on the floor brush body 10 and reducing the difficulty of assembling the roller brush cover 12 and the floor brush body 10.

[0167] Specifically, one of the first positioning portion 15 and the second positioning portion 33 is a positioning post, and the other is a positioning slot, with the positioning post and the positioning slot being positioned in a cooperative manner. For example, the second positioning portion 33 on the roller brush cover 12 has a positioning slot that opens downward, while the first positioning portion 15 is configured as a positioning post. The positioning post slides along the positioning slot and is fixed in a predetermined cooperative position. This assembly method of guiding and positioning the positioning slot and the positioning post can improve the assembly accuracy between the first positioning portion 15 and the second positioning portion 33, thereby facilitating and reducing the difficulty of assembly.

[0168] Furthermore, as shown in Figures 11, 13, and 14, there are multiple first positioning portions 15, which are spaced apart on the floor brush body 10, and there are multiple second positioning portions 33, which correspond one-to-one to the multiple first positioning portions 15 and the multiple second positioning portions 33. The multiple first positioning portions 15 are spaced apart on the floor brush body 10 and correspond one-to-one to the multiple second positioning portions 33. This increases the number of positioning portions used for assembly and positioning between the roller brush cover 12 and the floor brush body 10, thereby improving the positioning accuracy and connection strength between the roller brush cover 12 and the floor brush body 10, and preventing the problem of relative shaking between the roller brush cover 12 and the floor brush body 10.

[0169] Specifically, as shown in Figures 11, 13 and 14, a plurality of first positioning portions 15 are respectively arranged on both sides of the first locking portion 14, and the plurality of first positioning portions 15 are symmetrically arranged with respect to the first locking portion 14. For example, two first positioning portions 15 are respectively arranged on both sides of the first locking portion 14, but are not limited thereto. The line between the two first positioning portions 15 constitutes a connecting line, which can further ensure the relative position accuracy of the roller brush cover 12 and the floor brush body 10, thereby ensuring that the locking member 31 installed on the roller brush cover 12 can accurately enter into a locking cooperation relationship with the first locking portion 14. In addition, the plurality of first positioning portions 15 are symmetrically arranged with respect to the first locking portion 14, so that the structural positions of the plurality of first positioning portions 15 on the floor brush body 10 can be standardized, so that the plurality of first positioning portions 15 are arranged regularly, thereby improving processing and manufacturing efficiency.

[0170] According to some embodiments of the present application, as shown in Figures 17-18, the roller brush assembly 20 includes a roller brush 27 and a connecting member 22, one end of the roller brush 27 is provided with a first clamping portion 231, and the other end of the roller brush 27 is transmission-connected to the driving device 40, one end of the connecting member 22 is provided with a second clamping portion 221, the first clamping portion 231 and the second clamping portion 221 are clamped together, and the other end of the connecting member 22 is connected to the floor brush body 10, so that the connecting member 22 can be removed from the floor brush body 10 when the roller brush 27 needs to be cleaned, and the roller brush 27 can be separated from the connecting member 22 when the roller brush 27 needs to be replaced.

[0171] Specifically, the roller brush assembly 20 consists of a roller brush 27 and a connecting member 22. The roller brush 27 is the cleaning part of the floor brush 100. One end of the roller brush 27 is connected to the connecting member 22, and the other end is connected to the driving member for transmission. In this way, the roller brush 27 can be rotatably fixed on the floor brush body 10, and the roller brush 27 is driven to rotate by the driving device 40 to scrub the floor, so that stains and dirt can be effectively separated and removed.

[0172] Among them, one end of the connecting member 22 is connected to the roller brush 27, and the other end is connected to the floor brush body 10. The roller brush 27 and the floor brush body 10 can be connected to support the rotation of the roller brush 27. The user operates the floor brush body 10 to make the roller brush 27 brush the floor and complete the cleaning of the floor.

[0173] However, the roller brush 27 of the cleaning equipment will gradually wear out during long-term use, especially the bristles of the roller brush 27 will become weak, bent or fall off. The worn roller brush 27 cannot effectively clean the floor, affecting the cleaning effect. However, the connecting part 22 will not be damaged due to long-term use of the roller brush 27. Replacing the roller brush 27 together with the connecting part 22 will result in higher replacement costs for users, which is not conducive to environmental protection.

[0174] Therefore, a first clamping portion 231 is provided at one end of the roller brush 27, and a second clamping portion 221 is provided at one end of the connector 22. The first clamping portion 231 and the second clamping portion 221 engage with each other to achieve a clamping connection between the roller brush 27 and the connector 22. In other words, the roller brush 27 and the connector 22 are configured as a detachable structure. When the roller brush 27 needs to be replaced, the roller brush assembly 20 is first removed from the floor brush body 10, and then the roller brush 27 and the connector 22 are separated. The roller brush 27 can be replaced alone, which reduces the user's replacement cost and the generation of excessive waste materials, thereby being environmentally friendly.

[0175] Furthermore, the clamping method between the first clamping portion 231 and the second clamping portion 221 is relatively simple, so the disassembly between the connecting member 22 and the roller brush 27 can be facilitated.

[0176] That is, when the roller brush 27 needs to be cleaned, the connecting member 22 is removed from the floor brush body 10. In other words, when the roller brush 27 needs to be cleaned, the connecting member 22 and the roller brush 27 are removed from the floor brush body 10 to clean the roller brush 27. After cleaning, the connecting member 22 and the roller brush 27 can be installed. This arrangement can facilitate the cleaning of the roller brush 27.

[0177] Furthermore, when the roller brush 27 needs to be replaced, the roller brush 27 is separated from the connecting member 22. In other words, when the roller brush 27 needs to be replaced, the connecting member 22, which connects the roller brush 27 to the floor brush body 10, is removed, and the roller brush 27 is then removed from the connecting member 22 to replace the roller brush 27. This arrangement allows the roller brush 27 to be removed from the connecting member 22 and replaced separately, thereby reducing replacement costs for users.

[0178] Therefore, by providing the first clamping portion 231 and the second clamping portion 221 on the roller brush 27 and the connecting member 22, the roller brush 27 can be removed from the connecting member 22 and replaced separately, thereby reducing the user's replacement cost, reducing the generation of excessive waste materials, and being beneficial to environmental protection.

[0179] As shown in Figures 17-20, the roller brush 27 includes a roller brush body 21 and a clip 23. The clip 23 is connected to the roller brush body 21. A first clip 231 is provided on the outside of the clip 23. The connector 22 and the clip 23 are clipped together. In other words, the roller brush 27 is divided into two parts: the roller brush body 21 and the clip 23. The roller brush body 21 is connected to the clip 23, and the clip 23 is connected to the connector 22, thereby achieving the connection between the roller brush 27 and the connector 22. The clip 23 is a cylindrical structure with a first clip 231 provided on the outside of the clip 23. The clip 23 is clipped together with the connector 22 via the first clip 231.

[0180] As shown in Figure 21, a clamping protrusion is provided on the outer periphery of the clamping member 23, and the clamping protrusion surrounds the peripheral side of the clamping member 23. The clamping protrusion constitutes a first clamping portion 231. A hook is provided on the connecting member 22, and the hook constitutes a second clamping portion 221. The hook and the clamping protrusion are clamped together. That is to say, a circle of protrusions, namely the first clamping part 231, is provided on the outer periphery of the cylindrical part of the clamping part 23, and a hook, namely the second clamping part 221, is provided on the connecting part 22. The hook is a deformable structure. When the connecting part 22 and the clamping part 23 contact, due to the clamping protrusions on the outer periphery of the clamping part 23, the hook is slightly deformed in a direction perpendicular to the axis of the roller brush 27, leaving space for the clamping protrusion to pass through. After the clamping protrusion passes, the hook returns to its original position. At this time, the clamping protrusion is confined between the side wall of the connecting part 22 and the hook and will not fall off. In this way, the detachable roller brush 27 and the connecting part 22 can be used to complete the assembly of the roller brush assembly 20 without affecting the cleaning function.

[0181] Moreover, since the outer periphery of the clamping part 23 is provided with a clamping protrusion, that is, when the hook is clamped to the clamping protrusion, regardless of whether the angles of the connecting part 22 or the clamping part 23 in the circumferential direction are consistent, the clamping protrusion can be clamped to the hook, thereby improving the clamping efficiency between the clamping protrusion and the hook.

[0182] The mating surfaces of the engaging protrusion and the engaging hook are close to arc surfaces, which can reduce the resistance during assembly and improve the efficiency of assembly and disassembly.

[0183] In addition, the first clamping portion 231 can also be a clamping groove. The hook is slightly deformed and stretched in a direction perpendicular to the axis of the roller brush 27. After reaching the clamping groove, the hook returns to its original position. At this time, the hook is confined in the clamping groove, and the first clamping portion 231 and the second clamping portion 221 are clamped together.

[0184] Similarly, the engaging groove may surround the circumference of the engaging member 23 , which may facilitate the engaging fit between the engaging hook and the engaging groove.

[0185] Furthermore, the second clamping portion 221 may also be other retractable structures, which can utilize the retractable function in conjunction with the clamping protrusion or the clamping groove to limit the roller brush 17, thereby achieving a fixed connection between the roller brush 27 and the connector 22.

[0186] 19-20 , the roller brush 27 further includes a fastener 25 and a fixing member 24. The fixing member 24 is fixedly connected to the roller brush body 21. The fastener 25 passes through the clamping member 23 and is fixedly connected to the fixing member 24. Specifically, the fixing member 24 is a cylindrical structure. The fixing member 24 is sleeved on the outside of the clamping member 23 and part of the connecting member 22. The roller brush body 21 is sleeved on the outside of the fixing member 24. The fixing member 24 is used to fix the roller brush body 21. The fastener 25 passes through the clamping member 23 and is fixedly connected to the fixing member 24. In this way, the roller brush body 21, the fixing member 24, the clamping member 23, and the connecting member 22 can be fixedly connected.

[0187] Among them, the outer periphery of the fixing part 24 is provided with a snap-fit ​​rib, the diameter of which is larger than the inner diameter of the roller brush body 21, so that the fixing part 24 can be interference fit with the roller brush body 21, thereby achieving fixation between the fixing part 24 and the roller brush body 21.

[0188] In addition, the fastener 25 can be a screw, the clamping member 23 is provided with a mounting hole, and the fixing member 24 is provided with a screw hole, that is, the screw passes through the mounting hole and is fixedly connected to the screw hole, thereby fixing the clamping member 23 and the fixing member 24 together.

[0189] 19-20 , the roller brush 27 further includes a gasket 26, which is sandwiched between the fastener 25 and the clip 23. The fastener 25 passes through the gasket 26 and the clip 23 and is fixedly connected to the fixing member 24. The gasket 26 sandwiched between the fastener 25 and the clip 23 can, on the one hand, compensate for uneven, rough, or slightly defective mounting surfaces, increase friction, and effectively prevent assembly loosening, reducing the effects of loosening and vibration. On the other hand, it can disperse the pressure between the fastener 25 and the clip 23, transferring it more evenly to the clip 23, which helps reduce material deformation and damage and improves connection reliability.

[0190] As shown in Figure 20 , the side of the clamping member 23 facing the gasket 26 is provided with at least two third clamping portions 232. The third clamping portions 232 engage with the gasket 26. The third clamping portions 232 may be hook structures that engage the outer periphery of the gasket 26, thereby securing the gasket 26 to the clamping member 23. That is, during installation, the gasket 26 is first engaged within the third clamping portions 232, and then the fastener 25 is installed. This makes the operation more convenient and helps improve assembly efficiency and accuracy.

[0191] 19-20 , a mating protrusion 222 is provided on the side of the connector 22 facing the clip 23, and a mating groove 233 is provided on the side of the clip 23 facing the connector 22. The mating protrusion 222 fits into the mating groove 233. The mating protrusion 222 and the clip 23 cooperate with each other through the mating protrusion 222 and the mating groove 233. This not only improves the assembly stability between the connector 22 and the clip 23, but also shortens the distance between the fastener 25 connecting the clip 23 and the fixing member 24, reducing the volume occupied by the connector 22 and the clip 23. This reduces material usage, lowers production costs, and is environmentally friendly.

[0192] In addition, a flange is provided on the side of the mating protrusion 222 facing the fastener 25, and the flange abuts against the bottom wall of the mating groove 233, so that an avoidance space can be formed between the end face of the mating protrusion 222 and the bottom face of the mating groove 233, and the end of the fastener 25 can be avoided through the avoidance space.

[0193] As shown in Figures 19-21, there can be multiple second clamping portions 221, which are spaced apart on the side of the connector 22 facing the roller brush 27. In the embodiment of the present application, there are two second clamping portions 221, which are arranged along the side of the connector 22 facing the roller brush 27 and are symmetrically distributed perpendicular to the axis of the roller brush 27. Of course, the number of second clamping portions 221 can be three, four, or more according to different needs.

[0194] According to the embodiment of the present application, the floor brush 100 includes a drive device 40, which is arranged on one side of the floor brush body 10. One end of the roller brush assembly 20 is connected to the floor brush body 10, and the other end of the roller brush assembly 20 is in transmission cooperation with the drive device 40. The connecting member 22 is detachably connected to the floor brush body 10. That is, the user operates the floor brush body 10 to move the roller brush 27, and the drive device 40 drives the roller brush 27 to scrub the floor, completing the cleaning of the floor. The connecting member 22 is provided with a release button, and the floor brush body 10 is provided with a locking structure that cooperates with the release button. Pressing the release button can remove the roller brush assembly 20 from the floor brush body 10.

[0195] 18-19 , the floor brush body 10 is provided with a fourth clamping portion 16, and the connecting member 22 is provided with a fifth clamping portion 223. The fourth clamping portion 16 and the fifth clamping portion 223 are engaged with each other. Specifically, a groove is formed on the side of the floor brush body 10, and the connecting member 22 is placed in the groove. The fourth clamping portion 16 is provided in the groove, and the fifth clamping portion 223 is provided on the connecting member 22. The fourth clamping portion 16 and the fifth clamping portion 223 are engaged with each other to securely connect the connecting member 22 to the floor brush body 10.

[0196] According to the second aspect of the present application, the floor brush 100 includes a floor brush body 10, a roller brush assembly 20 and a diverter 313. The roller brush assembly 20 is rotatably arranged on the floor brush body 10. The diverter 313 includes a water squeezing portion facing the roller brush assembly 20 and a plurality of water outlets 3137. The diverter 313 is rotatably arranged on the floor brush 100. The water outlets 3137 transport cleaning liquid to the roller brush assembly 20. The water squeezing portion maintains contact with the roller brush assembly 20 to scrape off stains on the surface of the roller brush assembly 20 and squeeze out the sewage in the roller brush assembly 20 when the roller brush assembly 20 rotates.

[0197] Therefore, by setting up the floating scraper assembly 30, the diverter 313 can drive the water squeezing part to rotate slightly toward the side of the roller brush assembly 20 as the floor brush 100 wears, so that the water squeezing part and the roller brush assembly 20 always maintain contact, thereby avoiding the problem of increased residual water on the cleaning surface due to the wear of the floor brush 100.

[0198] In one embodiment, the diverter 313 includes a curved surface 315 facing the roller brush assembly 20, with a water outlet 3137 located on the curved surface 315. An elastic member 32 is provided on the side of the diverter 313 facing away from the curved surface 315. The elastic member 32 provides floating support for the diverter 313 to maintain contact between the water squeezing portion and the roller brush assembly 20. This allows the diverter 313 to spray clean water on the roller brush assembly 20 to remove dirt while maintaining contact between the water squeezing portion and the roller brush assembly 20 due to the elastic force of the elastic member 32, thereby preventing the floor brush 100 from increasing the amount of residual water when cleaning the work surface.

[0199] According to the third aspect of the present application, the cleaning device 200 includes the floor brush 100 of the above-described embodiment. This cleaning device 200, equipped with the floor brush 100, can ensure that the water-squeezing scraper 314 maintains contact with the roller brush assembly 20, thereby preventing the problem of increased residual water on the cleaning surface due to roller wear of the floor brush 100. The cleaning device 200 equipped with the floor brush 100 can selectively lock the roller brush cover 12 and the floor brush body 10 by rotating the operating portion 3011, thereby reducing the effort required for user disassembly and assembly. Furthermore, the assembly is simple, thereby improving its practicality and convenience. The type of cleaning device 200 can be determined based on actual needs and is not limited in this embodiment. The remaining components of the cleaning device 200, excluding the floor brush 100, can adopt the corresponding structures and shapes of various vacuum cleaners, such as handheld vacuum cleaners, canister vacuum cleaners, upright vacuum cleaners, and bucket vacuum cleaners. Alternatively, the remaining components of the cleaning device 200 can adopt the corresponding structures and shapes of other cleaning devices 200 with vacuuming functions, which are not limited in this embodiment.
