[0026] In the embodiment shown in the attached drawings, a first shaft head mounting position 11 is provided on one side of the trough 10, and a second shaft head mounting position 12 is provided on the other side of the trough 10. When installing the brush roller assembly 30, the fixed shaft head 33 is placed in the first shaft head mounting position 11 and fixed in cooperation with the first shaft head mounting position 11. The transmission shaft head 34 is placed in the second shaft head mounting position 12 and fixed to the trough 10 through the housing 341 of the transmission shaft head 34, thereby installing the brush roller assembly 30 in the trough 10. The end of the transmission shaft head 34 away from the brush roller 31 is connected to a sprocket 40. The drive mechanism is a motor, and the motor is connected to the sprocket 40 through a chain.

[0027] In the embodiment shown in the attached drawings, the fixed shaft head 33 is fixedly connected to the bearing hole of the bearing 36 by means of interference fit or adhesive bonding, and the outer ring of the bearing 36 is fixedly connected to the cylindrical hole 311 of the brush roller 31 by means of interference fit or adhesive bonding, so that the fixed shaft head 33 is rotatably connected to one end of the brush roller 31. Moreover, a sealing ring 37 is provided at the connection between the fixed shaft head 33 and the brush roller 31 to achieve an effective sealing effect. The fixed shaft head 33 has a through hole inside, and the universal joint 35 fixedly connected to the fixed shaft head 33 communicates with the cylindrical hole 311 of the brush roller 31 through the through hole inside the fixed shaft head 33.

[0028] In some embodiments, the brush roller 21 is provided with a plurality of stepped holes 312 communicating with the inside and outside of the brush roller 31. The stepped holes 312 include a first cylindrical hole 3121 and a second cylindrical hole 3122 concentrically connected to the first cylindrical hole 3121. The first cylindrical hole 3121 extends radially inward from the outer wall of the brush roller 31, and the second cylindrical hole 3122 extends radially outward from the inner wall of the brush roller 31. The diameter of the first cylindrical hole 3121 is larger than the diameter of the second cylindrical hole 3122. The brush head assembly 32 includes a brush head body 321, a spray nozzle 323, and a spring 322. The brush head body 321 includes a telescopic part 3211 that can slide in conjunction with the second cylindrical hole 3122, a first limiting part 3212 connected to one end of the telescopic part 3211 and adapted to the first cylindrical hole 3121, and a second limiting part 3213 connected to the other end of the telescopic part 3211. A water inlet hole 3214 is provided on the circumference of one end of the telescopic part 3211 near the second limiting part 3213. An opening communicating with the water inlet hole 3214 and a plurality of bristles 324 arranged around the opening are provided on one end of the brush head body 321 near the first limiting part 3212. The spray nozzle 323 is fixedly installed at the opening and has spray holes 3233. The brush head assembly 32 is snapped into the stepped hole 312. The telescopic part 3211 of the brush head body 321 is inserted into the second cylindrical hole 3122 of the stepped hole 312. One end of the spring 322, which is sleeved on the outside of the telescopic part 3211, abuts against the first limiting part 3212, and the other end abuts against the stepped surface of the stepped hole 312 (the bottom surface of the first cylindrical hole 3121 excluding part of the second cylindrical hole 3122).

[0029] When the brush head assembly 32 is squeezed without pressure, the brush head body 321 moves upward under the action of the spring 322, and the water inlet 3214 enters the second cylindrical hole 3122 and is blocked, thereby blocking the channel between the spray hole 3233 of the brush head assembly 32 and the cylindrical hole 311 of the brush roller 31; when the brush head assembly 32 is squeezed under pressure, the brush head body 321 moves downward, and the water inlet 3214 enters the cylindrical hole 311 of the brush roller 31, thereby connecting the channel between the spray hole 3233 of the brush head assembly 32 and the cylindrical hole 311 of the brush roller 31.

[0030] In the embodiment shown in the accompanying drawings, four water inlets 3214 are provided on the circumference of one end of the telescopic part 3211 near the second limiting part 3213; in other embodiments, the number of water inlets 3214 may be three, five or other numbers.

[0031] In the embodiment shown in the accompanying drawings, the spray nozzle 323 is a tower-shaped spray nozzle. The spray nozzle 323 includes a cylindrical connecting part 3231 and a cap 3232 connected to the connecting part 3231. The top of the cap 3232 is a conical surface, and a plurality of spray holes 3233 are evenly arranged on the conical surface and communicate with the cylindrical hole of the connecting part 3231.

[0032] In some other embodiments, the brush head assembly 32 includes only the brush head body 321 and the spring 322, but does not include the spray nozzle. The spray hole 3233 is directly disposed on the end of the brush head body 321 near the first limiting part 3212, and the bristles 324 are disposed around the spray hole 3233 on the end of the brush head body 321 near the first limiting part 3212.

[0033] The shoe sole cleaning machine of the present invention has two working modes: water washing and dry cleaning.

[0034] In water washing mode, the universal joints 35 of each brush roller assembly 30 are connected to water pipes, which are connected to tap water or a high-pressure water tank. The drive shaft head 34, driven by a motor, drives the brush roller 31 to make a circular motion. When the user's shoe sole is stepped on the grid bracket 20, the part of the brush head assembly 32 that is stepped on and squeezed retracts into the brush roller 31 to a certain space. The channel between the spray holes 3233 of the brush head assembly 32 and the cylindrical holes 311 of the brush roller 31 is connected, and the spray liquid from the spray holes 3233 sprays liquid to clean the sole and the bristles 324. During the cleaning process, because the brush head assembly 32 can move radially along the brush roller 31, the bristles 324 can match the depth and shape of the sole texture. Therefore, the sole corresponding to the squeezed brush head assembly 32 can be cleaned in a concentrated manner, thereby achieving a highly efficient cleaning effect. Moreover, the telescopic movement of the brush head assembly 32 can effectively control the opening and closing of the spray channel, which can effectively prevent the spray liquid from splashing randomly.

[0035] In dry cleaning mode, the universal joints 35 of each brush roller assembly 30 are connected to the vacuum hose, which is connected to a vacuum cleaner. The drive shaft head 34, driven by the motor, drives the brush roller 31 to make a circular motion. When the user's shoe sole is stepped on the grid support 20, the part of the brush head assembly 32 that is stepped on and squeezed retracts into the brush roller 31 to a certain space. The channel between the spray holes 3233 of the brush head assembly 32 and the cylindrical holes 311 of the brush roller 31 is connected, allowing for simultaneous brushing and vacuuming. During the cleaning process, because the brush head assembly 32 can extend and retract along the radial direction of the brush roller 31, the bristles 324 can match the depth and shape of the sole texture, allowing for concentrated cleaning of the sole corresponding to the squeezed brush head assembly 32, thus achieving a highly efficient cleaning effect. Moreover, the extension and retraction of the brush head assembly 32 can effectively control the opening and closing of the vacuum channel, effectively controlling flying dust.

[0036] The shoe sole cleaning machine of the present invention includes a tank 10, a grid support 20, a drive mechanism, and several brush roller assemblies 30. Each brush roller assembly 30 has a brush head assembly 32 on its brush roller 31, which can extend and retract radially along the brush roller 31. This allows the bristles 324 of the brush head assembly 32 to conform to the depth and shape of the shoe sole texture, enabling concentrated cleaning of the shoe sole corresponding to the compressed brush head assembly 32, thus achieving a highly efficient cleaning effect. Furthermore, the extension and retraction of the brush head assembly 32 effectively controls the opening and closing of the spray / vacuum channels, effectively preventing indiscriminate spraying of spray liquid or effectively controlling flying dust. In addition, the brush head assembly 32 is connected to the brush roller 31 via a snap-fit ​​mechanism, allowing for independent and quick replacement of the brush head assembly 32. When an individual brush head assembly 32 is damaged, only the damaged brush head assembly 32 needs to be replaced, without replacing the entire brush roller 31. This effectively improves maintenance efficiency and saves on operating costs. Finally, the spray nozzle 323 of the brush head assembly 32 adopts a tower-shaped spray nozzle, which can effectively prevent dirt accumulation and improve the flow of liquid / gas.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any way. Those skilled in the art can make various equivalent changes and improvements based on the above embodiments, and all equivalent variations or modifications made within the scope of the claims should fall within the protection scope of the present invention.
