[0045] In combination Figure 4 In some embodiments of the utility model, the first transmission part 12 has a first half part 121 and a second half part 122 distributed along the axial direction of the rolling brush unit 10, the first half part 121 has a first matching surface 1211 and a second matching surface 1212 corresponding to the circumferential direction of the rolling brush unit 10. Exemplarily, when the motor 21 is reversed, the second transmission part 22 can be matched with the first matching surface 1211, and when the motor 21 is forward rotated, the second transmission part can be matched with the second matching surface 1212.

[0046] In addition, the first transmission part 12 has a first half part 121 and a second half part 122 distributed along the axial direction of the rolling brush unit 10, the second transmission part 22 can be butt-jointed with the first transmission part 12 along the axial direction of the rolling brush unit 10. Exemplarily, the first half part 121 and the second half part 122 can be connected, and the second half part 122 is arranged obliquely relative to the first half part 121, after the second transmission part 22 of the driving unit 20 is installed into the installation cavity 111 and butt-jointed with the first transmission part 12, the second transmission part 22 can be limited through the cooperation of the first half part 121 and the second half part 122, the rolling brush unit 10 and the driving unit 20 can be prevented from falling off, and the cooperation stability of the rolling brush unit 10 and the driving unit 20 can be improved.

[0048] In combination Figures 4 to 8 In some embodiments of the present application, in the direction from the second half part 122 to the first half part 121: the first matching surface 1211 extends along the axial direction or is inclined relative to the axial direction towards the direction of the second matching surface 1212; and the second matching surface 1212 extends along the axial direction or is inclined relative to the axial direction towards the direction of the first matching surface 1211, thereby facilitating the processing and manufacturing of the rolling brush unit 10. Exemplarily, the main body part 11 and the first transmission part 12 can be integrally formed by an injection molding process, in which Figure 7 , the first matching surface 1211 and the second matching surface 1212 can extend along Figure 4 the direction of B2→B1, by extending the first matching surface 1211 along the axial direction or inclining it towards the direction of the second matching surface 1212, and extending the second matching surface 1212 along the axial direction or inclining it towards the direction of the first matching surface 1211, the first half part 121 does not hinder the mold when the mold is separated from the rolling brush unit 10 along the direction of B2→B1, thereby facilitating the demolding of the rolling brush unit 10 and improving the manufacturing efficiency of the rolling brush unit 10.

[0049] It should be noted that the first matching surface 1211 or the second matching surface 1212 described above extends along the axial direction, which means that the first matching surface 1211 is parallel or substantially parallel to the axis of the rolling brush unit 10, and the second matching surface 1212 is parallel or substantially parallel to the axis of the rolling brush unit 10. Substantially parallel means that the matching surface and the axis of the rolling brush unit 10 are basically the same in direction, with some slight deviation. Exemplarily, the matching surface and the axis of the rolling brush unit 10 can have an included angle of 5°.

[0050] In combination Figure 4Further, the second half 122 has a third matching surface 1221 and a fourth matching surface 1222 opposite along the circumference of the roller brush unit 10, wherein the third matching surface 1221 is connected with the first matching surface 1211 and extends obliquely, the fourth matching surface 1222 is connected with the second matching surface 1212 and extends obliquely, and the third matching surface 1221 and the fourth matching surface 1222 have the same oblique direction. Specifically, the third matching surface 1221 is arranged obliquely relative to the first matching surface 1211, so as to facilitate the cooperation between the first transmission part 12 and the second transmission part 22 after the abutment, the third matching surface 1221 cooperates with the second transmission part 22 to provide a force towards the axial center of the roller brush unit 10, and the fourth matching surface 1222 extends obliquely relative to the second matching surface 1212, so as to facilitate the cooperation between the first transmission part 12 and the second transmission part 22 after the abutment, the fourth matching surface 1222 cooperates with the second transmission part 22 to provide a force towards the axial center of the roller brush unit 10. Wherein the motor 21 can rotate forward and reverse, and exemplarily, when the motor 21 reverses, the second transmission part 22 cooperates with the third matching surface 1221, and when the motor 21 rotates forward, the second transmission part 22 cooperates with the fourth matching surface 1222.

[0051] In combination with Figure 7 and Figure 8 , exemplarily, when the first transmission part 12 and the main body part 11 are integrally formed by injection molding, the roller brush unit 10 can be formed by a mold cavity formed by closing the first mold half and the second mold half, and when demolding, the first mold half and the second mold half can be demolded towards opposite directions, wherein, Figure 7 D1 in the figure shows the parting line of the first mold half, Figure 8 D2 in the figure shows the parting line of the second mold half, that is, the edge line contacted when the first mold half and the second mold half are closed, wherein the first mold half is demolded along the direction of B2→B1, and the second mold half is demolded along the direction of B1→B2, by setting the first matching surface 1211 to extend along the axial direction or obliquely relative to the axial direction towards the direction of the second matching surface 1212, and setting the second matching surface 1212 to extend along the axial direction or obliquely relative to the axial direction towards the direction of the first matching surface 1211, the first half 121 can be avoided to hinder the separation of the first mold half and the roller brush unit 10, thereby facilitating the demolding of the roller brush unit 10 and improving the manufacturing efficiency of the roller brush unit 10.

[0052] In combination with Figure 6Further, the included angle between the first fitting surface 1211 and the third fitting surface 1221 is greater than the included angle between the second fitting surface 1212 and the fourth fitting surface 1222. Specifically, the included angle between the first fitting surface 1211 and the third fitting surface 1221 is α, and the included angle between the second fitting surface 1212 and the fourth fitting surface 1222 is β, where α > β. By increasing the included angle between the first fitting surface 1211 and the second fitting surface 1212, the demolding of the roller brush unit 10 is facilitated. In addition, the included angle between the second fitting surface 1212 and the fourth fitting surface 1222 is small, which facilitates the cooperation between the second transmission part 22 and the first transmission part 12 when the motor 21 is in forward rotation, so as to provide an axial central force to the roller brush unit 10, thereby enabling the roller brush unit 10 to automatically return to the original position. For example, α can be 159°, 161°, 168°, etc., and β can be 138°, 140°, 143°, etc.

[0053] Exemplarily, the included angle α between the first fitting surface 1211 and the third fitting surface 1221 satisfies 150° ≤ α ≤ 170°. Wherein, the included angle between the first fitting surface 1211 and the third fitting surface 1221 is less than or equal to 170°, which avoids that the included angle between the first fitting surface 1211 and the third fitting surface 1221 is too large, so that the cooperation area between the second transmission part 22 and the first transmission part 12 is too small when the motor 21 is in reverse rotation, thereby affecting the transmission stability; the included angle between the first fitting surface 1211 and the third fitting surface 1221 is greater than or equal to 150°, which avoids that the included angle between the first fitting surface 1211 and the third fitting surface 1221 is too small, thereby affecting the demolding of the roller brush unit 10. For example, α can be 159°, 161°, 168°, etc.

[0054] Exemplarily, the included angle β between the second fitting surface 1212 and the fourth fitting surface 1222 satisfies 130° ≤ β < 150°. Wherein, the included angle between the second fitting surface 1212 and the fourth fitting surface 1222 is less than 150°, which facilitates the abutment between the first transmission part 12 and the second transmission part 22, and after the abutment between the first transmission part 12 and the second transmission part 22, the first transmission part 12 and the second transmission part 22 are facilitated to cooperate, so that the motor 21 guides the roller brush unit 10 to return to the original position when rotating, thereby improving the working stability of the floor brush assembly 100; the included angle between the first fitting surface 1211 and the third fitting surface 1221 is greater than or equal to 130°, which avoids that the included angle between the second fitting surface 1212 and the fourth fitting surface 1222 is too small, thereby affecting the abutment between the roller brush unit 10 and the driving unit 20. For example, β can be 138°, 140°, 143°, etc.

[0055] In combination Figure 5 Figure 6 In some embodiments of the present application, in the projection along the axial direction, the length of the third fitting surface 1221 is less than the length of the fourth fitting surface 1222. For example, Figure 6As shown, the length of the third matching surface 1221 is L1, and the length of the fourth matching surface 1222 is L2. Exemplarily, the third matching surface 1221 is separated from the mold in the direction of B2→B1, and the fourth matching surface 1222 is separated from the mold in the direction of B1→B2, and the length of the third matching surface 1221 is smaller, which can facilitate the demolding of the rolling brush unit 10 and improve the manufacturing efficiency of the rolling brush unit 10.

[0056] In addition, the second transmission part 22 can include a third half part 223 and a fourth half part 224 distributed along the axial direction of the rolling brush unit 10, the third half part 223 has a fifth matching surface and a sixth matching surface opposite in the circumferential direction of the rolling brush unit 10. The fourth half part 224 has a seventh matching surface and an eighth matching surface opposite in the circumferential direction. Exemplarily, when the motor 21 is reversed, the first matching surface 1211 and the fifth matching surface are in contact, and the second matching surface 1212 and the sixth matching surface are in contact, and when the motor 21 is rotated in the positive direction, the third matching surface 1221 and the seventh matching surface are in contact, and the fourth matching surface 1222 and the eighth matching surface are in contact. In combination with the foregoing, the design of the first matching surface 1211 reduces the matching area between the rolling brush unit 10 and the driving unit 20 when reversed, and by increasing the size of the eighth matching surface, it is convenient to stably drive the first transmission part 12 to rotate through the second transmission part 22 when the motor 21 is reversed, and improve the matching stability of the rolling brush unit 10 and the motor 21 unit when the motor 21 is reversed.

[0057] In combination with Figure 9 and Figure 10 In some embodiments of the present application, the first transmission part 12 further comprises an annular rib 123, the first half part 121 and the second half part 122 are connected to the inner side of the annular rib 123, and the second transmission part 22 further comprises a positioning column 221 and a positioning flange 222, the positioning column 221 is provided through the annular rib 123, and the positioning flange 222 is connected to one end of the positioning column 221 and protrudes from the outer circumferential surface of the positioning column 221.

[0058] In addition, the first half 121 is farther away from the positioning flange 222 than the second half 122, that is, the second half 122 is closer to the positioning flange 222, the first half 121 is parallel or close to parallel to the axis of the roller brush unit 10, facilitating demolding of the roller brush unit 10, and the second half 122 is connected to the first half 121 and is arranged obliquely, facilitating cooperation of the first transmission part 12 and the second transmission part 22 to guide the roller brush unit 10 to the home position, and limiting the roller brush unit 10 by the positioning flange 222 when the roller brush unit 10 is in the home position, improving the cooperation stability of the roller brush unit 10 and the driving unit 20.
