Driven roller 203 side is slidably installed at the through slide groove 204 of roll brush side plate 201 by driven roller hinged seat 205, so driven roller 203 can be close to or away from driving roller 202.

[0044] As Figures 1-5As shown, the brush roller assembly 2 further comprises a control lock 4 for locking the driven roller hinged seat 205 at one side of the through sliding slot 204, after the driven roller hinged seat 205 is locked at the brush roller side plate 201, the driving roller 202 and the driven roller 203 are parallel arranged at this time; in particular, the control lock 4 is provided with a first lock catch 401, and the brush roller side plate 201 is correspondingly provided with a second lock catch 206 at one side of the through sliding slot 204, which can cooperate with the first lock catch 401; when changing the cloth, the first lock catch 401 of the control lock 4 is manually controlled to be disengaged from the second lock catch 206, at this time, the driven roller 203 can move towards the driving roller 202 along the through sliding slot 204, and the brush 3 can be taken off from the driving roller 202 and the driven roller 203.

[0045] It should be pointed out that the control lock 4 is movably arranged at one side of the brush roller side plate 201, which can be arranged to be directly taken off from the brush roller side plate 201, or can be arranged to be rotatably installed at one side of the brush roller side plate 201 or the driven roller hinged seat 205.

[0046] In an example, as shown in Figure 4 and Figure 8 , the first lock catch 401 is a clamping protrusion, and the second lock catch 206 is a clamping groove. Of course, the first lock catch 401 can also be a clamping groove, and the second lock catch 206 can be a clamping protrusion.

[0047] It should be pointed out that in the embodiment, the control lock 4 can be locked or unlocked by a finger, without the need to use other tools, so that the structure is simple and the operation is convenient.

[0048] As shown in Figure 3 , when the first lock catch 401 of the control lock 4 cooperates with the second lock catch 206, the driving roller 202 and the driven roller 203 are parallel arranged, and at this time, the brush 3 is tensioned on the driving roller 202 and the driven roller 203.

[0049] As shown in Figure 3 , the brush roller assembly 2 adopts a track-type brush roller, and the driving roller 202 and the driven roller 203 are arranged side by side; the contact area of the brush 3 with the surface to be cleaned (such as the ground) is large, and the cleaning efficiency is high.

[0050] In some embodiments, as shown in Figure 5A sliding block 207 is arranged on the driven roller hinged seat 205 and slidingly installed in the through sliding groove 204. Specifically, the sliding block 207 is fixed on the driven roller hinged seat 205 through the through sliding groove 204, so that the entire driven roller hinged seat 205 can slide at the through sliding groove 204. The control lock 4 is rotatably installed on the sliding block 207 through a hinge pin, and the control lock 4 is flipped and buckled on the second lock catch 206 when the floor brush main body 1 is working. By manually poking the control lock 4 to flip relative to the sliding block 207, the locking or releasing of the driven roller hinged seat 205 and the roller brush side plate 201 can be realized.

[0051] In some embodiments, referring to Figure 5 , the sliding block 207 is provided with a guide column 208 in sliding cooperation with the through sliding groove 204. The guide column 208 can be a square or a column structure. In the present embodiment, the guide column 208 is a column structure.

The conical guide seat 102 and the conical hole 214 cooperate to provide a centering and guiding function, which facilitates the quick installation and positioning of the driven roller 203; Figure 6 As shown, a motor assembly 5 that drives and cooperates with the drive roller 202 is also provided on one side of the roller brush groove 101. In this embodiment, the guide seat 102 is rotatably installed in the roller brush groove 101 of the floor brush body 1.

[0057] like Figure 7 As shown, after the roller brush assembly 2 is installed in the roller brush groove 101 of the main body of the floor brush 1, the motor assembly 5 is inserted into the drive roller 202, and the driven roller 203 is inserted into the conical guide seat 102 on the side away from the roller brush side plate 201. The motor shaft of the motor assembly 5 drives the drive roller 202 to rotate, and drives the driven roller 203 to rotate through the tensioned roller cloth 3.

[0058] In another embodiment, such as Figures 9-10 As shown, in this embodiment, the outer diameters of the driving roller 202 and the driven roller 203 are the same, and their motor assembly 5 is not built into the driving roller 202; as Figure 10 As shown, a first connecting seat 104 is provided on one side of the active roller 202, and a second connecting seat 105 is provided on one side of the driven roller 203. The first connecting seat 104 and the second connecting seat 105 are used to rotatably mount the active roller 202 and the driven roller 203 in the roller brush groove 101. In this embodiment, the motor assembly 5 built into the brush body 1 transmits power to the first connecting seat 104, driving the entire active roller 202 to rotate, and in turn driving the roller cloth 3 and the driven roller 203 to rotate. It should be noted that the setting of the position of the motor assembly 5 and how the motor assembly 5 drives the active roller 202 are conventional settings in the field of cleaning machines, and will not be described in detail in this embodiment.

[0059] In some embodiments, a disassembly knob 6 is provided on the roller brush side plate 201, and a positioning buckle 103 is provided on one side of the floor brush body 1. By rotating the disassembly knob 6, the roller brush side plate 201 can be fixed or detached from the floor brush body 1, which will not be described in detail in this embodiment.

[0060] The same or similar parts between the various embodiments in this specification can be referred to mutually. Each embodiment focuses on describing the differences from other embodiments.

[0061] The above merely provides the specific implementation of the present application, but the protection scope of the present application is not limited to this. Any changes or replacements within the technical scope disclosed by the present application can be easily conceived by the person skilled in the art, and should be covered within the protection scope of the present application.
