[0049] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0050] Combine the following Figure 1-Figure 10 , describing an embodiment of the present invention.

[0051] According to an embodiment of the present invention, on the one hand, a roller brush cloth automatic replacement device is provided, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the roller brush cloth automatic replacement device is used to peel the roller brush cloth 112 of the roller brush 110 off the roller brush cylinder 111. The roller brush cloth 112 is detachably wrapped around the outer circumference of the roller brush cylinder 111 and has a head end 1121 and a tail end 1122 close to each other.

[0052] Specifically, Figure 4 As shown, an adhesive layer 114 is provided between the roller brush cylinder 111 and the roller brush cloth 112, and the adhesive layer 114 is used to detachably connect the roller brush cloth 112 to the outer peripheral side of the roller brush cylinder 111. The adhesive layer 114 can specifically be a matching structure of the hook surface and the fleece surface in Velcro, so that the roller brush cloth 112 can be easily removed from the roller brush cylinder 111 when disassembling it, or it can be firmly connected to the entire circumference of the roller brush cylinder 111 when assembling the roller brush cloth 112; the outer contour of the roller brush cloth 112 is rectangular, wherein the two opposite sides are set as the head end 1121 and the tail end 1122, after the roller brush cloth 112 is assembled to the roller brush cylinder 111, the other two opposite sides of the roller brush cloth 112 are bent into a circle, and the head end 1121 and the tail end 1122 are set close to each other.

[0053] The roller brush cloth automatic replacement device comprises: a main structure 210 and a blocking member 270 .

[0054] The main structure 210 is used to place the roller brush 110; the blocking member 270 is arranged on the main structure 210. When the roller brush 110 is placed on the main structure 210, the joint between the head end 1121 of the roller brush cloth 112 and the roller brush cylinder 111 is opposite to the blocking member 270, so that when the roller brush 110 is driven to rotate, the blocking member 270 can peel the roller brush cloth 112 off the roller brush cylinder 111 along the head end 1121 to the tail end 1122.

[0055] In the above embodiment, when the cleaning device with the roller brush 110 is placed on the main structure 210, the joint between the head end 1121 of the roller brush cloth 112 on the roller brush 110 and the roller brush cylinder 111 is opposite to the blocking member 270 on the main structure 210. As the roller brush 110 is driven to rotate, the blocking member 270 peels the roller brush cloth 112 off the roller brush cylinder 111 along the joint from the head end 1121 to the tail end 1122, thereby realizing the automatic disassembly operation of the roller brush cloth 112. The operation is simple and efficient, and solves the problem that users currently need to manually replace the roller brush cloth, which is time-consuming and labor-intensive.

[0056] Specifically, Figure 3 , Figure 4As shown, a concave cavity is provided on the top surface of the main structure 210, and the concave cavity is used to place the cleaning equipment and the roller brush 110 used for cleaning; the blocking member 270 is provided in the concave cavity, the bottom of the blocking member 270 is connected to the concave cavity, and the top is arranged obliquely upward; when the cleaning equipment is placed in the concave cavity of the main structure 210, the top position of the blocking member 270 is opposite to the joint between the head end 1121 of the roller brush 110 and the roller brush cylinder 111, and as the roller brush cylinder 111 is driven to rotate in a clockwise direction, the top of the blocking member 270 is inserted into the joint, and as the roller brush 110 is driven to rotate one circle, the roller brush cloth 112 can be peeled off the roller brush cylinder 111 along the head end 1121 to the tail end 1122, and the disassembled roller brush cloth 112 is more convenient for thorough cleaning.

[0057] Furthermore, the present embodiment does not limit the specific structural form of the blocking member 270. The blocking member 270 can be set to a block shape. In this case, the blocking member 270 is set at the middle position of the corresponding roller brush 110. When the roller brush 110 is driven to rotate, the blocking member 270 extends into the seam position at the middle position, so that the speed at which the two side parts of the roller brush cloth 112 are peeled off is consistent; or the blocking member 270 is set to a long strip with a length equivalent to the roller brush 110. When the roller brush 110 is driven to rotate, the blocking member 270 extends into all the seam positions, so that all positions of the roller brush cloth 112 parallel to the head end 1121 are peeled off synchronously.

[0058] Furthermore, by setting an internal program in the cleaning device to rotate the roller brush 110 to a fixed position, it is ensured that when the cleaning device is placed on the main structure 210, the joint between the head end 1121 of the roller brush cloth 112 on the roller brush 110 and the roller brush cylinder 111 is facing the blocking member 270 on the main structure 210.

[0059] In some embodiments, Figure 3 As shown, the roller brush cloth automatic replacement device also includes: a cloth stroking mechanism.

[0060] The cloth stroking mechanism is arranged below the blocking member 270 and is provided with a cloth stroking channel 220 facing the outside of the automatic roller brush cloth changing device; when the roller brush cloth 112 is removed, the cloth stroking mechanism can receive the head end 1121 of the roller brush cloth 112 and drive the head end 1121 of the roller brush cloth 112 along the cloth stroking channel 220 to guide to the outside of the automatic roller brush cloth changing device; when the roller brush cloth 112 is assembled, the cloth stroking mechanism can receive the tail end 1122 of the roller brush cloth 112 and drive the tail end 1122 of the roller brush cloth 112 along the cloth stroking channel 220 to guide to the roller brush cylinder 111.

[0061] In the above embodiment, the cloth stroking mechanism can provide a driving force to drive the roller brush cloth 112 to guide the roller brush cylinder 111, thereby realizing the automatic installation operation of the roller brush cloth 112; at the same time, the cloth stroking channel 220 provides a path for the disassembly and installation of the roller brush cloth 112, ensuring the smoothness of the disassembly and installation of the roller brush cloth 112 and avoiding obstruction of the movement of the roller brush cloth 112.

[0062] Specifically, Figure 3 As shown, when the roller brush cloth 112 is removed, the cloth-smoothing mechanism receives the head end 1121 of the roller brush cloth 112 and provides a driving force to the roller brush cloth 112 to drive the roller brush cloth 112 along the head end 1121 to the tail end 1122, thereby cooperating with the rotational driving force of the roller brush 110 itself under the driving force of the cleaning device, ensuring that the roller brush cloth 112 has sufficient driving force to be smoothly removed from the roller brush cylinder 111 and guided along the cloth-smoothing channel 220. The outside of the roller brush cloth automatic replacement device; when assembling the roller brush cloth 112, the cloth stroking mechanism can receive the tail end 1122 of the roller brush cloth 112, and provide driving force to the roller brush cloth 112 along the tail end 1122 to the head end 1121 to drive the roller brush cloth 112, thereby driving the roller brush cloth 112 along the cloth stroking channel 220 to guide the roller brush cylinder 111, and cooperate with the roller brush cylinder 111 to be driven to rotate counterclockwise, thereby realizing the automatic installation operation of the roller brush cloth 112.

[0063] Furthermore, a scraper strip 130 is also provided on the cleaning device where the roller brush 110 is located, and the scraper strip 130 is pressed against the roller brush 110 through a torsion spring to wipe the water on the roller brush 110; when the roller brush cloth 112 is guided along the cloth stroking channel 220 and assembled to the roller brush cylinder 111, the scraper strip 130 abutting against the roller brush 110 can apply force to the roller brush cloth 112, so that the roller brush cloth 112 is firmly assembled to the outer wall of the roller brush cylinder 111.

[0064] In some embodiments, Figure 3 As shown, the cloth stroking mechanism includes a first transmission roller 230 and a second transmission roller 240 , and a cloth stroking channel 220 is provided between the first transmission roller 230 and the second transmission roller 240 . The first transmission roller 230 and the second transmission roller 240 can be driven to rotate to drive the roller brush cloth 112 to move along the cloth stroking channel 220 .

[0065] In the above embodiment, the cloth-smoothing mechanism guides and drives the roller brush cloth 112 through the coordinated transmission of the first transmission roller 230 and the second transmission roller 240, and the structure is simple and the transmission is stable.

[0066] Specifically, Figure 3As shown, when removing the roller brush cloth 112, the first transmission roller 230 rotates clockwise and the second transmission roller 240 rotates counterclockwise, thereby providing a driving force from the head end 1121 to the tail end 1122 to the roller brush cloth 112 after receiving the head end 1121 of the roller brush cloth 112; when assembling the roller brush cloth 112, the side of the roller brush cloth 112 that is in contact with the roller brush cylinder 111 faces upward, the first transmission roller 230 rotates counterclockwise, and the second transmission roller 240 rotates clockwise, thereby providing a driving force from the head end 1121 to the head end 1121 to the roller brush cloth 112 after receiving the tail end 1122 of the roller brush cloth 112.

[0067] In some embodiments, Figure 5 , Figure 6 As shown, the cloth-smoothing mechanism further includes a roller motor group 250 drivingly connected to the first transmission roller 230 and the second transmission roller 240. The roller motor group 250 is used to drive the first transmission roller 230 and the second transmission roller 240 to rotate in opposite directions.

[0068] In the above embodiment, the first transmission roller 230 and the second transmission roller 240 are driven by the roller motor group 250 to rotate in opposite directions to each other, so that the cloth-smoothing mechanism drives the roller brush cloth 112 when the roller brush cloth 112 is disassembled or assembled.

[0069] Specifically, Figure 6 As shown, the first transmission roller 230 and the second transmission roller 240 are of the same length as the roller brush 110, and the roller motor group 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 connected to the first transmission roller 230 and the second transmission roller 240 through two direct drive motors or one drive motor in combination 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.

[0070] Furthermore, the drum motor group 250 is communicatively connected with a signal switch 290, and the signal switch 290 is communicatively connected with the blocking member 270 and can be triggered by the blocking member 270. When the roller brush cloth 112 is assembled, when the blocking member 270 is subjected to a clockwise force from the roller brush 110, the signal switch 290 senses the pressure change from the blocking member 270, generates a control signal and transmits it to the drum motor group 250, thereby controlling the drum motor group 250 to start so that the cloth-smoothing mechanism can automatically operate.

[0071] In some embodiments, Figure 3 As shown, a cloth changing opening 260 is provided on the outer wall of the main structure 210 , and the cloth changing opening 260 is communicated with a side of the cloth stroking passage 220 away from the blocking member 270 .

[0072] In the above embodiment, a cloth changing port 260 connected to the cloth stroking channel 220 is provided so that the roller brush cloth 112 can be guided from the cloth changing port 260 to the outside of the roller brush cloth automatic replacement device, or the roller brush cloth 112 can be introduced from the cloth changing port 260 for assembly.

[0073] Specifically, the cloth changing opening 260 is disposed on the outer shell of the brush cloth automatic changing device, and the length of the cloth changing opening 260 is greater than the length of the leading end 1121 and the trailing end 1122 of the roller brush cloth 112 .

[0074] In some embodiments, Figure 3 , Figure 4 As shown, the blocking member 270 can be rotatably arranged on the main structure 210, and has a raised state and a dropped state; when the blocking member 270 is in the raised state, the blocking member 270 can be aligned with the joint between the head end 1121 of the roller brush cloth 112 and the roller brush cylinder 111, so as to be inserted into the joint to peel the roller brush cloth 112 off the roller brush cylinder 111; when the blocking member 270 is in the dropped state, the blocking member 270 can avoid the roller brush 110, so that the roller brush 110 can perform self-cleaning when being driven.

[0075] In the above embodiment, the blocking member 270 is rotatably disposed on the main structure 210 to prevent the blocking member 270 from interfering with the roller brush 110 when the roller brush 110 performs self-cleaning.

[0076] Specifically, Figure 3 , Figure 4 As shown, the bottom of the blocking member 270 is rotatably connected to the concave cavity of the main structure 210. When the cleaning device where the roller brush 110 is located performs self-cleaning on the roller brush 110, the roller brush 110 is driven to rotate counterclockwise, and at this time, the blocking member 270 is in a falling state, thereby avoiding the roller brush 110 and allowing it to smoothly perform the self-cleaning operation of rotating counterclockwise. When the roller brush cloth 112 is removed, the roller brush 110 is driven to rotate clockwise, and at this time, the blocking member 270 is in a raised state, so that the top of the blocking member 270 has a sufficient height to be inserted into the joint between the head end 1121 of the roller brush cloth 112 and the roller brush cylinder 111.

[0077] In some embodiments, Figure 3 , Figure 4 , Figure 7 As shown, a reset member 280 is provided between the blocking member 270 and the main structure 210 , and the reset member 280 can reset the blocking member 270 from a dropped state to a raised state.

[0078] In the above embodiment, the blocking member 270 is kept in a raised state in the final state after being driven by the reset member 280. When the cleaning device with the roller brush 110 is placed on the main structure 210, it is ensured that the top position of the blocking member 270 is aligned with the joint between the head end 1121 of the roller brush 110 and the roller brush cylinder 111, so as to ensure that the roller brush cloth 112 can be disassembled quickly.

[0079] Specifically, the reset member 280 can be specifically configured as a torsion spring, a spring, etc. between the blocking member 270 and the main structure 210, and the potential energy of the elastic deformation is released to restore the lifted position of the blocking member 270.

[0080] In some embodiments, Figure 7 As shown, the blocking member 270 is configured as a long strip structure, and the reset member 280 is configured as a torsion spring and is disposed at the rotating shaft at the end of the blocking member 270 .

[0081] In the above embodiment, the blocking member 270 is configured as a long strip structure so that various positions of the rolling brush cloth 112 parallel to the head end 1121 can be simultaneously peeled off the rolling brush cylinder 111 .

[0082] Specifically, the blocking member 270 is configured as a long strip having a length equivalent to that of the roller brush 110 . When the roller brush 110 is driven to rotate, the blocking member 270 extends into all seam positions, so that all positions of the roller brush cloth 112 parallel to the head end 1121 are peeled off synchronously.

[0083] Furthermore, comb teeth are provided on the top of the blocking member 270 to improve the smoothness of peeling off the roller brush cloth 112.

[0084] According to an embodiment of the present invention, on the other hand, a rolling brush mechanism is also provided. Figure 1 , Figure 8 , Fig. 9 , Fig.10 As shown, the roller brush mechanism can be placed in the automatic roller brush cloth replacement device of the above-mentioned embodiment of the implementation method.

[0085] The roller brush mechanism includes a roller brush 110 and a roller brush motor 120 .

[0086] The roller brush 110 comprises a roller brush cylinder 111 and a roller brush cloth 112 which is detachably wrapped around the outer peripheral side of the roller brush cylinder 111; a cavity 1111 is arranged inside the roller brush cylinder 111, and a magnetic strip 113 is arranged at the tail end 1122 of the roller brush cloth 112; a roller brush motor 120 is arranged in the cavity 1111 in transmission connection with the roller brush 110, and is used to drive the roller brush 110 to rotate, and the outer shell of the roller brush motor 120 is an energized magnetic outer shell 121; when the roller brush motor 120 is energized, the magnetic strip 113 presses the head end 1121 of the roller brush cloth 112 against the outer wall of the roller brush cylinder 111; when the roller brush motor 120 is powered on, the head end 1121 of the roller brush cloth 112 is separated from the outer wall of the roller brush cylinder 111.

[0087] In the above embodiment, when the roller brush motor 120 is powered on, the powered magnetic shell 121 and the magnetic strip 113 are magnetically attracted to each other so that the magnetic strip 113 holds the head end 1121 of the roller brush cloth 112 close to the outer wall of the roller brush cylinder 111, thereby preventing 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 powered magnetic shell 121 and the magnetic strip 113 are magnetically attracted to each other so that the head end 1121 of the roller brush cloth 112 is separated from the outer wall of the roller brush cylinder 111, thereby facilitating the insertion of the blocking member 270 into the joint between the head end 1121 of the roller brush cloth 112 and the roller brush cylinder 111 for automatic disassembly of the roller brush cloth 112.

[0088] Specifically, Figure 3 , Fig. 9 As shown, since the roller brush cloth 112 is detachably wrapped around the outer peripheral side of the roller brush cylinder 111 and can be automatically disassembled for cleaning or replacement, there is no need to disassemble and replace the roller brush 110 as a whole, which facilitates cleaning and saves replacement costs. 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 to save installation space.

[0089] Furthermore, the energized magnetic housing 121 has a unidirectional magnetic property, that is, Figure 3 , Fig. 9 As shown, when the roller brush motor 120 is powered on to drive the roller brush 110 to rotate counterclockwise, the powered magnetic shell 121 generates a magnetic attraction to cooperate with the magnetic strip 113. At this time, the roller brush 110 of the roller brush mechanism can perform self-cleaning or normal operation; when the roller brush motor 120 is powered on to drive the roller brush 110 to rotate clockwise, the powered magnetic shell 121 does not generate a magnetic attraction and cannot cooperate with the magnetic strip 113, so that the head end 1121 of the roller brush cloth 112 is separated from the outer wall of the roller brush cylinder 111. At this time, the roller brush 110 of the roller brush mechanism can disassemble the roller brush cloth 112.

[0090] Furthermore, if Figure 3 , Fig. 9 , Fig.10 As shown, the end of the roller brush motor 120 is provided with an assembly block 140, and the assembly block 140 has convex ribs that cooperate with the installation position of the roller brush motor 120 to achieve accurate installation and foolproofing. By setting an internal program in the cleaning device to rotate the roller brush 110 to a fixed position, that is, a position where the middle convex rib of the assembly block 140 faces downward, at this time, the head end 1121 and the tail end 1122 of the roller brush cloth 112 are close to each other and 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, which can ensure that the joint between the head end 1121 of the roller brush cloth 112 on the roller brush 110 and the roller brush cylinder 111 is facing the blocking member 270.

[0091] Furthermore, if Figure 3 , Fig. 9 , Fig.10 As shown, an angle mole switch 150 is provided on one side of the assembly block 140 and is in communication with the roller brush motor 120. When the roller brush cloth 112 is assembled and the tail end 1122 of the roller brush cloth 112 is guided to the roller brush cylinder 111 along the cloth stroking channel 220, the roller brush cylinder 111 will be driven to rotate a certain angle after the tail end 1122 of the roller brush cloth 112 contacts the roller brush cylinder 111. At this time, the angle mole switch 150 is triggered and generates a control signal to control the roller brush motor 120 to rotate counterclockwise, thereby cooperating with the cloth stroking mechanism to assemble the roller brush cloth 112.

[0092] In some embodiments, Figure 1 As shown, the roller brush mechanism 100 is configured as a floor scrubber, and the roller brush cloth automatic replacement device 200 is configured as a base station for the floor scrubber to be placed.

[0093] The operation method of the automatic roller brush cloth replacement device provided in this embodiment is as follows:

[0094] When the roller brush cloth 112 is removed, the roller brush 110 is rotated through the control button and the internal control program, so that the roller brush 1100 is rotated to the initial state where the middle rib of the assembly block 140 is facing downward, the head end 1121 and the tail end 1122 of the roller brush cloth 112 are close to each other and are located directly below the roller brush 110; the internal program controls the roller brush motor 120 to be powered off, and the magnetism of the magnetic shell 121 disappears when it is powered on, and the head 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 member 270 is inserted into the head end 1121 of the roller brush cloth 112 and the roller brush cylinder. 111 of the joint glass roller brush cloth 112; the blocking member 270 is subjected to the clockwise force from the roller brush 110 so that the signal switch 290 senses the pressure change from the blocking member 270, and generates a control signal to start the roller motor group 250 to make the cloth stroking mechanism automatically operate; the first transmission roller 230 of the cloth stroking mechanism rotates clockwise, and the second transmission roller 240 rotates counterclockwise to receive the head end 1121 of the roller brush cloth 112, and the roller brush cloth 112 is guided along the cloth stroking channel 220 to the outside of the roller brush cloth automatic changing device 200, and finally the roller brush cloth 112 is completely guided out from the cloth changing port 260, and the disassembly operation of the roller brush cloth 112 is completed.

[0095] When assembling the roller brush cloth 112, the roller motor group 250 is started through the control button and the internal control program, so that the first transmission roller 230 of the cloth-smoothing mechanism rotates counterclockwise, and the second transmission roller 240 rotates clockwise; the roller brush cloth 112 is introduced into the cloth-changing opening 260 from the cloth-changing opening 260 with the tail end 1122 in front and the head end 1121 in the back, and the side that is in contact with the roller brush cylinder 111 facing upward; the cloth-smoothing mechanism receives the tail end 1122 of the roller brush cloth 112 and drives The roller brush cloth 112 is guided to the roller brush cylinder 111 along the cloth stroking channel 220; after the tail end 1122 of the roller brush cloth 112 contacts the roller brush cylinder 111, it drives the roller brush cylinder 111 to rotate a certain angle. At this time, the angle Moore switch 150 is triggered and generates a control signal to control the roller brush motor 120 to rotate counterclockwise. After the roller brush cylinder 111 rotates counterclockwise for one circle, the roller brush cloth 112 is completely assembled to the outer peripheral wall of the roller brush cylinder 111, and the assembly operation of the roller brush cloth 112 is completed.
