The embodiment of the utility model provides a ground brush assembly. The floor brush assembly includes: a rolling brush component. Such as the roll brush assembly 100 shown in fig. 1. Fig. 1 is a schematic perspective view of an exemplary roll brush assembly according to some embodiments of the present utility model. As shown in fig. 1, the roll brush member 100 includes a roll brush base plate 110 and a roll brush 120. The roller brush 120 is fixed to the roller brush base plate 110. In some embodiments, the roller brush 120 is removably secured to the roller brush base plate 110. Thus, when the user needs to detach the roller brush 120, the user may detach the roller brush unit 100 from the floor brush assembly or the cleaning device, and detach the roller brush 120 from the roller brush base plate 110. Similarly, when the user needs to install the roller brush 120, the roller brush 120 may be installed on the roller brush base plate 110, and then the roller brush unit 100 may be installed on the floor brush assembly or the cleaning device. This facilitates the removal and attachment of the roller brush 120, and reduces the risk of the user being scratched by other components.

Referring to fig. 2, fig. 2 is an exploded view of fig. 1. As shown in fig. 1 and 2, the roll brush base plate 110 includes a roll brush base plate body 112 and a support structure 111. When the roller brush 120 is mounted on the roller brush base plate 110, the roller brush 120 is mounted on the roller brush base plate body 112. The roller brush 120 includes a roller (not shown), a brush body 122, two bearings (not shown), and two fixing members 124. Two fixing members 124 are fixed to the roll brush base plate 110. Specifically, the two fixing members 124 are detachably fixed to the roll brush base plate body 112 of the roll brush base plate 110. The roller penetrates the brush body 122 along the length direction of the brush body 122 and is fixed relative to the brush body 122. Both ends of the roller protrude from both ends of the brush body 122, respectively. The two bearings are respectively fixed to portions of the roller protruding from both ends of the brush body 122. The two fixing members 124 are respectively fixed to the two bearings such that the brush body 122 is rotatably connected to the two fixing members 124 through the bearings.

Further, the roller brush 120 may further include a driving wheel 125. The driving wheel 125 is fixed at one end of the roller, and is used for driving the roller and the brush 122 to rotate. In some embodiments, the floor brush assembly may include a belt for rotating the roller brush 120. The drive wheel is connected with the motor through a belt, and the motor of the cleaning device or the floor brush assembly drives the roller and the brush body 122 to rotate through the belt and the drive wheel 125. In some embodiments, the drive wheel 125 may be secured to the roller by a sleeve that is injection molded into the drive wheel 125, the sleeve being secured to the roller by an interference fit, thereby achieving a secure connection with the roller. The installation cost is lower through interference fit and injection molding, and the fixing is firm and stable.

Referring to fig. 3-6, fig. 3 is an exemplary structural schematic diagram of a floor brush assembly shown in accordance with some embodiments of the present utility model; fig. 4 is a schematic view of an exemplary structure of a bottom portion of a floor brush assembly according to some embodiments of the utility model, and fig. 5 is a schematic cross-sectional view taken along A-A in fig. 3. Fig. 6 is a schematic cross-sectional view taken along B-B in fig. 3. Referring to fig. 3-6, the floor brush assembly 200 includes a housing 210. The roll brush member 100 is accommodated in the housing 210. The roll brush base plate 110 of the roll brush assembly 100 comprises a support structure 111. Specifically, the supporting structure 111 may be a structure protruding from the roll brush base plate body 112 toward one side. The housing 210 is provided with a limiting structure 211. As shown in fig. 5 and 6, the housing 210 may include a fan housing 212, and the limiting structure 211 may be disposed on the fan housing 212. When the rolling brush part 100 is installed, the supporting structure 111 and the limiting structure 211 form a lever type structure, and the rolling brush part 100 is installed in the fan housing 212, that is, in the housing 210.

In some embodiments, the limiting structure 211 may also be disposed at other locations of the housing 210. For example, the housing 210 may further include an upper housing, a lower housing, etc., and the limiting structure 211 may be disposed on the upper housing or the lower housing. Further, the limiting structure 211 is not limited to one material, and may be composed of a plurality of materials. For example, the limiting structure 211 may be partially disposed on the upper case, partially disposed on the lower case, or the limiting structure 211 may be partially disposed on other parts of the case than the upper and lower cases. When the rolling brush component 100 is installed, the supporting structure 111 contacts with the limiting structure 211 at a contact position, and the supporting structure 111 takes the contact position as a fulcrum to drive the rolling brush component 100 to rotate around the fulcrum, so that the rolling brush component 100 is installed in the air inlet cover 212. In some embodiments, the pivot point is not fixed during installation of the roll brush member 100 and may vary as the contact location between the support structure 111 and the limit structure 211 changes. In general, the limiting structure 211 may be provided at any position on the housing 210 that may be in contact with the supporting structure 111 during the installation of the roll brush member 100. The position is only required to give the support structure 111 a pivot point about which the roll brush member 100 is rotated during installation of the roll brush member 100, so that the roll brush member 100 can be conveniently installed in the housing 210.

Referring to fig. 7-8, fig. 7 is a schematic cross-sectional view taken along A-A in fig. 3 of a roll brush installation procedure shown in accordance with some embodiments of the utility model; fig. 8 is a schematic cross-sectional view taken along B-B in fig. 3 of a roll brush installation procedure shown in accordance with some embodiments of the utility model. As shown in fig. 7-8, the floor brush assembly may include a motor and belt 240. When the roll brush 120 is mounted, the roll brush 120 is first fixed to the roll brush base plate 110 to form the integrated roll brush unit 100. The belt 240 is sleeved on the motor shaft 230 of the motor and the driving wheel 125 of the roller brush 120. And the supporting structure 111 on the rolling brush base plate 110 is abutted against the limiting structure 211 arranged on the fan housing 212. At this time, the belt 240 is loosened to reach a state as shown in fig. 7A and 8A. The user holds the rolling brush part 100 to apply a clockwise force, and the rolling brush part 100 rotates clockwise by taking the contact points of the supporting structure 111 and the limiting structure 211 as fulcrums. When the position of fig. 7B and 8B is reached, the belt 240 tightens. Without the cooperation of the support structure 111 and the limiting structure 211, the user would install the brush member without an application point, and the brush member would be offset and the installation would be very laborious. After adding the supporting structure 111 and the limiting structure 211, in the state of fig. 7B and 8B, the user can easily move the roll brush member 100 to the state of fig. 7C and C by applying a downward force, i.e., install the roll brush into the fan housing 212.

As shown in fig. 7, the spacing structure 211 may include a first side wall surface 2111 and a second side wall surface 2112. The first side wall surface 2111 and the second side wall surface 2112 are perpendicular to each other. The distal end of the support structure 111 may be placed under the second sidewall surface 2112 when the roll brush 100 is installed. The supporting structure 111 abuts against the limiting structure 211, and the contact point may be located on the first side wall surface 2111 or the second side wall surface 2112. The rolling brush member 100 rotates with the contact point as a fulcrum by the external force. When in the position of fig. 7B, the support structure 111 may slide upward without the second sidewall surface 2112, and the second sidewall surface 2112 may restrict the support structure 111 from sliding upward. Meanwhile, the second side wall surface 2112 may also give the supporting structure 111 a fulcrum function. Until the roll brush assembly 100 is mounted into the housing 212 by external force to the position of fig. 7C. And then the rolling brush base plate 110 is fixed with the fan housing 212, so that the installation of the rolling brush is completed.

In some embodiments, the second sidewall surface 2112 of the stop structure 211 may also move downward as shown in fig. 7. That is, when the roll brush member 100 is mounted, the supporting structure 111 is placed above the second side wall surface 2112, so that the limiting structure 211 can limit the downward sliding of the supporting structure 111 during the mounting process.

It should be noted that, the supporting structure 111 and the limiting structure 211 only play a role of lever in the installation process of the rolling brush 120, so that the force applied by the user on the rolling brush component 100 has a fixed direction relative to the acting force of the belt 240 on the rolling brush component 100, and the rolling brush component 100 cannot shake at will, so that the installation process of the rolling brush 120 is smoother, and the user experience is improved.

In some embodiments, the support structure and the spacing structure may also be interconnected shaft hole structures. For example, the support structure is provided with a shaft and the limit structure is provided with a hole, or the support structure is provided with a hole and the limit structure is provided with a shaft. When the rolling brush is installed, the supporting structure rotates by taking the shaft as a fulcrum. The shaft hole structure is used for realizing the function of pre-fixing and positioning the rolling brush bottom plate and the shell while playing a role of leverage, so that the installation smoothness is improved, and the user experience is improved.

Reference is made to fig. 9-15. Fig. 9-15 are exemplary schematic diagrams of spacing structures and support structures according to some embodiments of the present utility model.

As shown in fig. 9, the limiting structure 211 may include only the first side wall surface 2111. The direction of the plane of the first side wall surface 2111 is taken as a vertical plane, and a coordinate axis is established. The plane in which the first side wall surface 2111 is located is the YZ plane. When the roll brush member 100 is mounted, the support structure 111 abuts against the first side wall surface 2111, and rotates by an external force about the abutting position against the first side wall surface 2111 as a fulcrum, thereby mounting the roll brush in the housing. The first side wall surface 2111 of the limiting structure 211 as shown in fig. 9 may limit the movement of the support structure 111 or the roll brush member 100 in the X negative direction. Such a limiting structure 211 is simple in structure. The first side wall surface may be not only a side wall surface disposed in the vertical direction as shown in fig. 9, but also a side wall surface disposed in the horizontal direction or other directions. Correspondingly, the directions of the first side wall surfaces are different, and the limiting directions of the supporting structure are different.

As shown in fig. 10-13, the stop structure 211 may include a first side wall surface 2111 and a second side wall surface 2112, or include a first side wall surface 2111 and a third side wall surface 2113. The second side wall surface 2112 or the third side wall surface 2113 is connected to the first side wall surface 2111. Further, the second side wall surface 2112 or the third side wall surface 2113 may be perpendicular to the first side wall surface 2111. When the second side wall surface 2112 or the third side wall surface 2113 may be perpendicular to the first side wall surface 2111, a direction of a plane in which the first side wall surface 2111 is located is a vertical plane, and a coordinate axis is established. The plane in which the first side wall surface 2111 is located is a YZ plane, the plane in which the second side wall surface 2112 is located is an XY plane, and the plane in which the third side wall surface 2113 is located is an XZ plane. When the roll brush member 100 is mounted, one side of the second side wall surface 2112 or the third side wall surface 2113 abuts against the support structure 111 for restricting the sliding of the support structure 111 in the first direction or the second direction. As shown in fig. 10-11, the first side wall surface 2111 is in the YZ plane and the second side wall surface 2112 is in the XY plane. The second side wall surface 2112 may be a surface that restricts sliding movement of the support structure 111 in a vertical direction, i.e., in the Z-direction, upward or downward. As shown in fig. 12-13, the first side wall 2111 is in the YZ plane and the third side wall 2113 is in the XZ plane. Then, the third sidewall surface 2113 may be a surface that restricts sliding of the support structure 111 in the Y direction to the Y positive direction or the Y negative direction. It will be appreciated that the first side wall surface 2111 may also limit movement of the support structure 111 or the roll brush member 100 in the X direction. The first side wall surface, the second side wall surface, and the third side wall surface are not only three-directional side wall surfaces as shown in fig. 10 to 13, and the positions of the three side wall surfaces may be interchanged or not on mutually perpendicular planes. Correspondingly, the first, second or third side wall surfaces are arranged in different directions, and the limiting directions on the supporting structure are different.

Further, the limiting structure 211 may further include a first side wall surface 2111, a second side wall surface 2112 and a third side wall surface 2113, wherein the third side wall surface 2113 is connected to the first side wall surface 2111 and the second side wall surface 2112, or the third side wall surface 2113 is connected to the first side wall surface 2111 or the second side wall surface 2112. Further, the second and third side wall surfaces 2112 and 2113 and the first side wall surface 2111 may be perpendicular to each other. When the three side wall surfaces are perpendicular to each other, a coordinate axis is established by taking the direction of the plane of the first side wall surface 2111 as a vertical plane. The plane in which the first side wall surface 2111 is located is a YZ plane, the plane in which the second side wall surface 2112 is located is an XY plane, and the plane in which the third side wall surface 2113 is located is an XZ plane. For example, as shown in fig. 14. The first side wall surface 2111 is in the YZ plane, the second side wall surface 2112 is in the XY plane, and the third side wall surface 2113 is in the XZ plane. Then, the second side wall surface 2112 and the third side wall surface 2113 can restrict movement of the support structure 111 in the Y direction in the Y plus direction and sliding upward in the Z direction at the same time. The limit structure 211 comprises a first side wall surface 2111, a second side wall surface 2112 and a third side wall surface 2113, so that the limit function of the support structure is more complete, and a user can install the support structure more smoothly, so that the user experience is improved more effectively.

Further, the first side wall surface, the second side wall surface, and the third side wall surface may not be connected to each other. As long as the side wall surface forming the limiting structure can be contacted with the supporting structure in the installation and rotation process of the supporting structure, the supporting structure is acted by a fulcrum, and the movement of the supporting structure in the corresponding direction in the installation process can be limited.

Optionally or preferably, the limiting structure 211 may further include two second side wall surfaces 2112 and/or a third side wall surface 2113 disposed parallel to each other, and a distance between the two parallel side wall surfaces should be slightly greater than a width of the supporting structure 111. When the roll brush assembly 100 is installed, the support structure 111 is located between two parallel sidewall surfaces. The two parallel side wall surfaces are equivalent to forming a clamping groove structure, and the support structure 111 is limited in the clamping groove during installation, so that the support structure 111 can be limited to slide in the positive direction and the negative direction in the plane direction of the side wall surfaces at the same time. So that the installation of the rolling brush is smoother. As shown in fig. 15, the stopper structure may include a first side wall surface 2111 and two second side wall surfaces 2112 (2112-1, 2112-2) disposed parallel to each other along the XY plane, and a third side wall surface 2113 disposed along the XZ plane. Then, when the roll brush 100 is mounted, the first side wall surface 2111 may restrict the sliding of the support structure 111 in the X negative direction, the second side wall surface 2112-1 may restrict the sliding of the support structure 111 in the Z positive direction, the other second side wall surface 2112-2 may restrict the sliding of the support structure 111 in the Z negative direction, and the third side wall surface 2113 may restrict the sliding of the support structure 111 in the Y positive direction.

Still further, referring to fig. 15, the limiting structure may include one first side wall surface 2111, two second side wall surfaces 2112, and two third side wall surfaces 2113. The first side wall surface 2111, the second side wall surface 2112, and the third side wall surface 2113 are perpendicular to each other. The direction of the plane of the first side wall surface 2111 is taken as a vertical plane, and a coordinate axis is established. The plane in which the first side wall surface 2111 is located is a YZ plane, the plane in which the second side wall surface 2112 is located is an XY plane, and the plane in which the third side wall surface 2113 is located is an XZ plane. As the limiting structure 211 shown in fig. 15, the sliding of the support structure 111 in the XYZ three axes, five directions can be limited. In this way, through the design of the five side wall surfaces of the limiting structure 211, the movement in all directions can be limited in the process of installing the rolling brush, and the user installing process is more stable and smooth.

Further, the support structure 111 may be a flat bar structure or a structure with hooks as shown in fig. 9-15.

The embodiment also provides a cleaning device comprising the floor brush assembly provided by the embodiment. Referring to fig. 16-17, fig. 16 is an exemplary structural schematic view of a cleaning device according to some embodiments of the present utility model, and fig. 17 is a cross-sectional schematic view taken along B-B in fig. 15. As shown in fig. 16 and 17, a cleaning device 300, such as a vacuum cleaner, includes a floor brush assembly 200, and a roll brush assembly 100 is included in the floor brush assembly 200.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
