[0062] Specifically, as shown in Figure 3 when dismounting the rolling brush cloth 112, the cloth guiding mechanism receives the head end 1121 of the rolling brush cloth 112 and provides driving force to the rolling brush cloth 112 along the head end 1121 to the tail end 1122, driving the rolling brush cloth 112, so as to cooperate with the driving of the rolling brush 110 by the cleaning equipment, ensuring that the rolling brush cloth 112 has enough driving force to be smoothly dismounted from the rolling brush cylinder 111 and guided along the cloth guiding channel 220 to the outside of the rolling brush cloth automatic replacement device; when assembling the rolling brush cloth 112, the cloth guiding mechanism can receive the tail end 1122 of the rolling brush cloth 112 and provide driving force to the rolling brush cloth 112 along the tail end 1122 to the head end 1121, driving the rolling brush cloth 112 along the cloth guiding channel 220 to the rolling brush cylinder 111, cooperating with the counterclockwise rotation of the rolling brush cylinder 111, realizing automatic installation operation of the rolling brush cloth 112.

[0063] Further, the cleaning equipment on which the rolling brush 110 is located is also provided with a scraping strip 130, the scraping strip 130 abuts against the rolling brush 110 through a torsion spring to scrape water on the rolling brush 110; when the rolling brush cloth 112 is guided along the cloth guiding channel 220 and assembled to the rolling brush cylinder 111, the scraping strip 130 abutting against the rolling brush 110 can apply force to the rolling brush cloth 112, so that the rolling brush cloth 112 is firmly assembled to the outer wall of the rolling brush cylinder 111.

[0064] In some embodiments, as shown in Figure 3 the cloth guiding mechanism includes a first transmission cylinder 230 and a second transmission cylinder 240, the first transmission cylinder 230 and the second transmission cylinder 240 are provided with a cloth guiding channel 220 therebetween, and the first transmission cylinder 230 and the second transmission cylinder 240 can be driven to rotate to drive the rolling brush cloth 112 to move along the cloth guiding channel 220.

[0065] In the above embodiment, the cloth guiding mechanism realizes the guiding and driving of the rolling brush cloth 112 through the cooperative transmission of the first transmission cylinder 230 and the second transmission cylinder 240, which is simple in structure and stable in transmission.

[0066] Specifically, as shown in Figure 3As shown, when the roll brush cloth 112 is disassembled, the first transmission roller 230 rotates clockwise and the second transmission roller 240 rotates counterclockwise, thereby providing the driving force to the roll brush cloth 112 along the first end 1121 to the second end 1122 after receiving the first end 1121 of the roll brush cloth 112; when the roll brush cloth 112 is assembled, the side of the roll brush cloth 112 close to the roll brush cylinder 111 faces upward, the first transmission roller 230 rotates counterclockwise and the second transmission roller 240 rotates clockwise, thereby providing the driving force to the roll brush cloth 112 along the first end 1121 to the first end 1121 after receiving the second end 1122 of the roll brush cloth 112.

[0067] In some embodiments, as shown in Figure 5 , Figure 6 As shown, the cloth rolling mechanism further comprises a roller motor set 250 in transmission connection with the first transmission roller 230 and the second transmission roller 240, and the roller motor set 250 is used to drive the first transmission roller 230 and the second transmission roller 240 to rotate in opposite directions respectively.

[0068] In the above embodiments, the first transmission roller 230 and the second transmission roller 240 are driven by the roller motor set 250 to rotate in opposite directions respectively, so as to realize the driving effect of the cloth rolling mechanism on the roll brush cloth 112 when the roll brush cloth 112 is disassembled or assembled.

[0069] Specifically, as shown in Figure 6 The first transmission roller 230 and the second transmission roller 240 are equivalent in length to the roll brush 110, the roller motor set 250 is arranged on the main structure 210 on the same side of the first transmission roller 230 and the second transmission roller 240, and is in transmission connection with the first transmission roller 230 and the second transmission roller 240 through two direct-drive motors or one drive motor in cooperation with a transmission assembly, so as to achieve the purpose of driving the first transmission roller 230 and the second transmission roller 240 to rotate in opposite directions respectively.

[0070] Further, the roller motor set 250 is in communication connection with a signal switch 290, the signal switch 290 is in communication connection with the blocking piece 270 and can be triggered by the blocking piece 270. When the roll brush cloth 112 is assembled, the signal switch 290 senses the pressure change from the blocking piece 270 when the blocking piece 270 is subjected to the clockwise force from the roll brush 110, generates a control signal and transmits it to the roller motor set 250, so as to control the roller motor set 250 to start and make the cloth rolling mechanism automatically operate.

[0071] In some embodiments, as shown in Figure 3 The outer wall of the main structure 210 is provided with a cloth changing port 260, and the cloth changing port 260 is in communication with the side of the cloth rolling channel 220 away from the blocking piece 270.

[0074] In some embodiments, as shown in Figure 3 、 Figure 4 , the blocking piece 270 is rotatably arranged on the main structure 210 and has a raised state and a lowered state. When the blocking piece 270 is in the raised state, the blocking piece 270 can be opposite to the position of the joint between the first end 1121 of the rolling brush cloth 112 and the rolling brush cylinder 111, so as to insert the joint to peel off the rolling brush cloth 112 from the rolling brush cylinder 111. When the blocking piece 270 is in the lowered state, the blocking piece 270 can avoid the rolling brush 110, so that the rolling brush 110 can be self-cleaned when being driven.

[0075] In the above embodiments, the blocking piece 270 is rotatably arranged on the main structure 210, so as to avoid interference between the blocking piece 270 and the rolling brush 110 when the rolling brush 110 is self-cleaned.

[0076] Specifically, as shown in Figure 3 、 Figure 4 , the bottom of the blocking piece 270 is rotatably connected to the recess of the main structure 210. When the cleaning equipment in which the rolling brush 110 is arranged is self-cleaning the rolling brush 110, the rolling brush 110 is driven to rotate counterclockwise, and at this time, the blocking piece 270 is in the lowered state, thereby avoiding the rolling brush 110 and allowing it to smoothly rotate counterclockwise for self-cleaning. When the rolling brush cloth 112 is disassembled, the rolling brush 110 is driven to rotate clockwise, and at this time, the blocking piece 270 is in the raised state, so that the top of the blocking piece 270 has sufficient height to insert the joint between the first end 1121 of the rolling brush cloth 112 and the rolling brush cylinder 111.

[0077] In some embodiments, as shown in Figure 3 、 Figure 4 、 Figure 7 , the blocking piece 270 and the main structure 210 are provided with a reset piece 280, and the reset piece 280 can reset the blocking piece 270 from the lowered state to the raised state.

[0087] In the above embodiment, when the roller brush motor 120 is powered on, the power-on magnetic shell 121 is magnetically attracted to the magnetic attraction strip 113 to make the magnetic attraction strip 113 tightly attach the leading end 1121 of the roller brush cloth 112 to the outer wall of the roller brush cylinder 111, so as to avoid the roller brush cloth 112 from falling off and affecting the cleaning effect of the roller brush 110; when the roller brush motor 120 is powered off, the power-on magnetic shell 121 and the magnetic attraction strip 113 lose the magnetic attraction, so that the leading end 1121 of the roller brush cloth 112 is separated from the outer wall of the roller brush cylinder 111, thereby facilitating the blocking piece 270 to be inserted into the joint between the leading end 1121 of the roller brush cloth 112 and the roller brush cylinder 111, so as to automatically disassemble the roller brush cloth 112.

[0088] Specifically, as shown in Figure 3 , Figure 9 , since the roller brush cloth 112 is detachably wound around the outer periphery of the roller brush cylinder 111 and can be automatically disassembled for cleaning or replacement, the roller brush 110 does not need to be disassembled and replaced as a whole, which facilitates cleaning and saves replacement cost; at the same time, since the roller brush cylinder 111 does not need to be disassembled, the roller brush motor 120 can be hidden in the internal cavity 1111 of the roller brush cylinder 111, so as to save installation space.

[0089] Further, the power-on magnetic shell 121 has a one-way magnetic generation characteristic, that is, as shown in Figure 3 , Figure 9 , when the roller brush motor 120 is powered on to drive the roller brush 110 to rotate counterclockwise, the power-on magnetic shell 121 generates a magnetic attraction to cooperate with the magnetic attraction strip 113, so that the roller brush 110 of the roller brush mechanism can be self-cleaned or normally operated; when the roller brush motor 120 is powered on to drive the roller brush 110 to rotate clockwise, the power-on magnetic shell 121 does not generate a magnetic attraction and cannot cooperate with the magnetic attraction strip 113, so that the leading end 1121 of the roller brush cloth 112 is separated from the outer wall of the roller brush cylinder 111, and at this time the roller brush 110 of the roller brush mechanism can be disassembled.

[0090] Further, as shown in Figure 3 , Figure 9 , Figure 10 , the end of the roller brush motor 120 is provided with an assembly block 140, and the assembly block 140 has a convex rib which cooperates with the installation position of the roller brush motor 120 to accurately install and prevent mistakes. By setting an internal program in the cleaning equipment, the roller brush 110 is rotated to a fixed position, that is, the middle convex rib of the assembly block 140 is downward, and at this time the positions where the leading end 1121 and the trailing end 1122 of the roller brush cloth 112 are close to each other are located directly below the roller brush 110; when the roller brush 110 is in this position, the roller brush mechanism 100 is placed on the main structure 210, so that the leading end 1121 of the roller brush cloth 112 on the roller brush 110 is opposite to the blocking piece 270.

[0091] Further, as shown in Figure 3 , Figure 9 , Figure 10 , one side of the assembly block 140 is provided with an angle hall switch 150 in communication connection with the roller brush motor 120. The roller brush cloth 112 is assembled, and when the tail end 1122 of the roller brush cloth 112 is guided along the cloth guiding channel 220 to the roller brush cylinder 111, the tail end 1122 of the roller brush cloth 112 will drive the roller brush cylinder 111 to rotate a certain angle after contacting the roller brush cylinder 111. At this time, the angle hall switch 150 is triggered and generates a control signal to control the roller brush motor 120 to rotate counterclockwise, thereby cooperating with the cloth guiding mechanism to assemble the roller brush cloth 112.

[0092] In some embodiments, as shown in Figure 1 , the roller brush mechanism 100 is provided as a scrubber, and the roller brush cloth automatic replacement device 200 is provided as a base station for placing the scrubber.

[0093] The working mode of the roller brush cloth automatic replacement device provided by the embodiment is as follows:

[0094] When the roller brush cloth 112 is disassembled, the roller brush 110 is rotated by controlling the button and the internal control program, so that the roller brush 110 is rotated to the initial state in which the middle protruding rib of the assembly block 140 faces downward, and the first end 1121 and the tail end 1122 of the roller brush cloth 112 are close to each other and located directly below the roller brush 110. The internal program controls the roller brush motor 120 to be powered off, so that the magnetism of the power-on magnetic shell 121 disappears, and the first end 1121 of the roller brush cloth 112 is separated from the outer wall of the roller brush cylinder 111. The internal program controls the roller brush motor 120 to be powered on to drive the roller brush 110 to rotate clockwise, and the blocking piece 270 is inserted into the joint between the first end 1121 of the roller brush cloth 112 and the roller brush cylinder 111. The blocking piece 270 is subjected to the force from the clockwise direction of the roller brush 110, so that the signal switch 290 senses the pressure change of the blocking piece 270, generates a control signal to start the roller motor set 250, and the cloth guiding mechanism is automatically operated. The first transmission roller 230 of the cloth guiding mechanism rotates clockwise, and the second transmission roller 240 rotates counterclockwise to receive the first end 1121 of the roller brush cloth 112. The roller brush cloth 112 is guided along the cloth guiding channel 220 to the outside of the roller brush cloth automatic replacement device 200, and finally the roller brush cloth 112 is completely guided out of the cloth replacement opening 260, completing the disassembly operation of the roller brush cloth 112.

[0095] When the rolling brush cloth 112 is assembled, the first transmission roller 230 of the cloth rolling mechanism is driven to rotate counterclockwise and the second transmission roller 240 is driven to rotate clockwise by starting the roller motor set 250 through the control button and the internal control program; the rolling brush cloth 112 is guided into the cloth changing port 260 in a posture that the tail end 1122 is in front and the head end 1121 is in back and the side close to the rolling brush cylinder 111 faces upward; the cloth rolling mechanism receives the tail end 1122 of the rolling brush cloth 112 and drives the rolling brush cloth 112 to be guided along the cloth rolling channel 220 to the rolling brush cylinder 111; after the tail end 1122 of the rolling brush cloth 112 contacts the rolling brush cylinder 111, the rolling brush cylinder 111 is driven to rotate by a certain angle, at this time, the angle hall switch 150 is triggered and a control signal is generated to control the rolling brush motor 120 to rotate counterclockwise, after the rolling brush cylinder 111 rotates counterclockwise for one circle, the rolling brush cloth 112 is completely assembled to the outer peripheral wall of the rolling brush cylinder 111, and the assembly operation of the rolling brush cloth 112 is completed.

[0096] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes are intended to fall within the scope defined by the present application.
