Description

Technical Field

[0001] This utility model relates to the technical field of shoe cleaning equipment, specifically to a self-cleaning shoe sole cleaning machine. Background Technology

[0002] Although small, shoe soles bear the brunt of various hazards and stains brought in from the outside world. In the home, dirt brought in by shoe soles not only contaminates the floor but can also expose active children to illnesses through ingestion. Gravel can scratch precious wooden floors, increasing the cleaning burden. In special places like hospitals and food factories, uncleaned shoe soles can become accomplices in the spread of germs and foreign objects, threatening public health and safety. In public places such as kindergartens, exhibition halls, and farms, proper shoe sole cleaning protects both health and exhibits and livestock. Outdoors and in extreme weather, shoe sole cleaning is equally crucial, relating to safety and facility protection.

[0003] A cleaning machine for cleanroom workshops, disclosed in authorization announcement number (CN222109985U), includes a shoe sole cleaning machine body and multiple cleaning roller brushes. The multiple cleaning roller brushes are respectively arranged inside the shoe sole cleaning machine body, and two handles are fixedly installed at the top of the shoe sole cleaning machine body. In use, the user steps on the surface of the cleaning roller brushes, and with the movement of the cleaning roller brushes, dirt on the surface of the shoe sole can be scraped off, and the shoe sole may also get wet.

[0004] The structure disclosed in this patent has shortcomings in practical applications, specifically as follows: During shoe sole cleaning, it relies solely on the cleaning roller brush for physical surface cleaning, without utilizing the chemical action of the cleaning solution, making it difficult to effectively handle various complex stains. For stains containing organic components such as proteins and sugars (e.g., milk stains, urine stains), without the synergistic effect of enzyme-containing cleaning solutions and disinfectants, it not only fails to decompose organic matter but also easily leads to stain residue, putrefaction, foul odor, and bacterial growth. Therefore, this structure presents hygiene risks such as incomplete cleaning and bacterial residue, making it difficult to meet the practical needs of scenarios with high cleaning and sterilization requirements, such as medical and maternal and infant care. Utility Model Content

[0005] The purpose of this invention is to provide a self-cleaning shoe sole cleaning machine, which addresses the problem of stain residue and bacterial growth caused by the existing technology of cleaning shoe sole surfaces solely with physical roller brushes. This invention provides a solution to the problem of stain residue and bacterial growth caused by physical roller brush cleaning alone. It can improve the decomposition and removal of sticky stains and organic pollutants on shoe soles, and simultaneously perform antibacterial treatment.

[0006] This utility model is achieved through the following technical solution:

[0007] A self-cleaning shoe sole cleaning machine includes: a cleaning main unit, which is sequentially provided with a pre-cleaning area and a main cleaning area. The pre-cleaning area includes two opposing first assembly slots, and the main cleaning area includes two opposing second assembly slots; a support bracket, which is installed in the first assembly slots and has multiple assembly interfaces; multiple piston-type liquid storage tubes, which correspond one-to-one with the multiple assembly interfaces and are respectively installed in their corresponding assembly interfaces. The top of each piston-type liquid storage tube is a medium discharge port, and the bottom of each piston-type liquid storage tube is equipped with a sealing plunger; a drive assembly, which is connected to the multiple sealing plungers and can synchronously drive the multiple sealing plungers to reciprocate along the extension direction of the piston-type liquid storage tubes; and a brushing assembly, which is installed in the second assembly slots and can physically brush the shoe soles.

[0008] Furthermore, in this utility model, the aforementioned drive assembly includes a lifting execution plate, a drive spindle, a first motor, and multiple linkage push rods; the multiple linkage push rods correspond one-to-one with multiple sealing plungers, one end of each linkage push rod is connected to a corresponding sealing plunger, and the other end of each linkage push rod is connected to the lifting execution plate; the drive spindle passes through the lifting execution plate and is threadedly engaged with the lifting execution plate; the first motor is installed in the first assembly slot, and the output end of the first motor is connected to the drive spindle.

[0009] Furthermore, in this utility model, the above also includes a brush head body, which is fitted onto the outside of the piston-type liquid storage tube, and the brush head body can reciprocate along the extension direction of the piston-type liquid storage tube.

[0010] Furthermore, in this utility model, the above also includes a return spring, which is fitted onto the outside of the piston-type liquid storage tube. One end of the return spring is connected to the brush head body, and the other end of the return spring is connected to the outer wall of the piston-type liquid storage tube.

[0011] Furthermore, in this utility model, the above also includes a fluid distributor and a universal ball joint.

[0013] Furthermore, in this utility model, the top of the second assembly groove is equipped with a plurality of cantilever brackets along the extension direction, and a cleaning brush disc is provided between two adjacent cantilever brackets, with the cantilever brackets and the cleaning brush discs arranged alternately.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0015] 1. This application adopts a dual-zone collaborative design that combines quantitative release of cleaning liquid in the pre-cleaning zone with physical scrubbing in the main cleaning zone.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model. Example

[0027] Please refer to the reference. Figures 1 to 5 This utility model provides a self-cleaning shoe sole cleaning machine. The cleaning host 1 is provided with a pre-cleaning area 2 and a main cleaning area 3. The pre-cleaning area 2 includes two oppositely arranged first assembly slots 4, and the main cleaning area 3 includes two oppositely arranged second assembly slots 5. A support bracket 9 is installed in the first assembly slots 4, and the support bracket 9 is provided with multiple assembly interfaces 10. Multiple piston-type liquid storage tubes 11 correspond one-to-one with the multiple assembly interfaces 10 and are respectively installed in the corresponding assembly interfaces 10. The top end of the piston-type liquid storage tube 11 is a medium discharge port 22, and the bottom end of the piston-type liquid storage tube 11 is equipped with a sealing plunger 17.

[0028] The drive assembly connects to multiple sealing plungers 17 and can synchronously drive the multiple sealing plungers 17 to reciprocate along the extension direction of the piston-type liquid storage tube 11; the brushing assembly is installed in the second assembly tank 5 and can physically brush the sole of the shoe. In use, the user first passes through the pre-cleaning area 2, places both feet on the support brackets 9 in the first assembly tank 4, and contacts the media discharge ports 22 at the top of the multiple piston-type liquid storage tubes 11 with both feet. The drive assembly is controlled to drive the multiple sealing plungers 17 to move upward, so that the cleaning liquid in the piston-type liquid storage tube 11 is discharged from the media discharge ports 22 and adheres to the sole of the shoe. Then the feet enter the main cleaning area 3, where the brushing assembly performs physical brushing, thereby improving the cleaning efficiency of the sole of the shoe.

[0029] It should be noted that the cleaning solution can be flexibly selected according to usage needs. A neutral cleaning solution is recommended, free of strong acids and alkalis. It effectively breaks down stains such as grease and dust without causing corrosion, discoloration, or deformation to shoe sole materials (such as rubber, leather, and fabric). It is suitable for cleaning needs in various scenarios such as home, office, medical, and laboratory settings. For special stains (such as oil stains and pigments), a corresponding dedicated cleaning solution can be used. The system supports quick replacement of the reservoir tube or addition of compatible cleaning agents, ensuring cleaning effectiveness while protecting the materials.

[0030] After physically brushing the soles of their shoes in the second assembly slot 5 of the main cleaning area 3, the user proceeds to the rear section of the cleaning unit 1. The rear section is equipped with a drying cloth assembly made of a multi-layered fiber composite material (an ultra-fine fiber absorbent layer on the surface and an elastic sponge support layer at the bottom). The user can gently place the soles of their shoes on the cloth surface and, by slowly moving their feet, utilize the cloth's absorbency and friction to quickly remove residual moisture and minor stains from the soles.

[0031] Please refer to Figure 4 In some embodiments of this application, the drive assembly specifically includes a lifting actuator plate 14, a drive spindle 16, a first motor 15, and multiple linkage push rods 23. Each linkage push rod 23 is configured to correspond one-to-one with a sealing plunger 17 of the piston-type liquid reservoir 11: one end of each linkage push rod 23 is connected to the sealing plunger 17, and the other end of each linkage push rod 23 is fixedly connected to the lifting actuator plate 14, forming a synchronously driven linkage structure.

[0032] The drive spindle 16 vertically penetrates the center of the lifting execution plate 14, and the drive spindle 16 forms a precision thread engagement with the internal thread of the inner wall of the lifting execution plate 14. The first motor 15 is mounted on a motor bracket pre-set on the bottom wall of the first assembly slot 4, and the output end of the first motor 15 is coaxially connected to the drive spindle 16 through a coupling to ensure the stability and accuracy of power transmission.

[0033] During operation, the first motor 15 receives a control signal and begins to rotate, driving the drive spindle 16 to rotate synchronously. Based on the principle of threaded transmission, the rotational motion of the drive spindle 16 is converted into the linear lifting motion of the lifting actuator plate 14. During vertical movement, the lifting actuator plate 14 synchronously drives multiple sealing plungers 17 via the linkage push rod 23, causing the sealing plungers 17 to reciprocate along the axis of the piston-type liquid storage tube 11. When the sealing plungers 17 move upward, they can precisely push the cleaning fluid in the piston-type liquid storage tube 11, causing the cleaning fluid to be evenly squeezed out from the medium discharge port 22 at the top of the piston-type liquid storage tube 11 and adhere to the surface of the user's shoe sole, thus achieving a quantitative supply of cleaning fluid.

[0034] Please refer to Figure 5In some embodiments of this application, the pre-cleaning zone 2 is further provided with a brush head body 12, which is fitted onto the outside of the piston-type liquid storage tube 11 and forms a sliding fit structure. The brush head body 12 is made of elastic plastic material, and the inner wall of the brush head body 12 is slidably connected to the outer wall of the piston-type liquid storage tube 11. The brush head body 12 can reciprocate along the axial direction of the piston-type liquid storage tube 11.

[0035] When the user places the sole of the shoe on the top surface of the brush head body 12, the brush head body 12 moves downward along the liquid storage tube under pressure until the medium discharge port 22 at the top of the piston-type liquid storage tube 11 is flush with the top of the brush head body 12. At this time, the circumferentially distributed annular bristles of the brush head body 12 are in full contact with the sole of the shoe. When the user moves the sole slightly, the bristles of the brush head body 12 initially remove the surface dust of the sole through friction, while the sealing plunger 17 moves upward, pushing the cleaning liquid out from the medium discharge port 22, and evenly penetrating to the base of the bristles through the brush head body 12.

[0036] For example, the return spring 13 is fitted onto the outside of the piston-type liquid reservoir 11, forming an axial elastic support structure. One end of the return spring 13 is fixed to the bottom of the brush head body 12 via a snap-fit ​​structure, and the other end of the return spring 13 is connected to the outer wall of the piston-type liquid reservoir 11. When the user's shoe sole presses down on the brush head body 12, the brush head body 12 overcomes the spring force and slides axially downward along the piston-type liquid reservoir 11 until the medium discharge port 22 at the top of the piston-type liquid reservoir 11 is flush with the top of the brush head body 12. At this time, the return spring 13 is in a compressed state, and the brush head body 12 adheres to the sole surface with constant pressure through elastic reaction force, forcing the bristles to penetrate deep into the sole tread, significantly increasing friction and thus improving the pre-cleaning effect.

[0037] When the user lifts their foot away, the return spring 13 releases its elastic potential energy, driving the brush head body 12 to automatically slide upwards and reset along the piston-type liquid reservoir 11. The elastic cushioning design of the return spring 13 can adapt to different shoe sole thicknesses and curvatures (such as high heels, sneakers, etc.), ensuring that the brush head body 12 always maintains effective contact with the sole, while avoiding component wear caused by rigid collisions.

[0038] Please refer to Figure 5 In some embodiments of this application, a fluid distributor 18 and a universal ball joint 20 are also included. The fluid distributor 18 is detachably connected to the top end of the piston-type liquid storage pipe 11. The top end of the fluid distributor 18 is provided with a rotating ball groove 19, and the bottom end of the fluid distributor 18 is provided with a plurality of guide channels 21 communicating with the rotating ball groove 19. The universal ball joint 20 is installed in the rotating ball groove 19 and can rotate flexibly relative to the rotating ball groove 19.

[0039] The fluid distributor 18 is threadedly installed on the top of the piston-type liquid reservoir 11. When the two are connected, the cleaning fluid in the piston-type liquid reservoir 11 can flow into the rotating ball groove 19 through multiple guide channels 21. During the relative rotation of the universal ball head 20 and the rotating ball groove 19, the cleaning fluid will evenly adhere to the surface of the universal ball head 20. When the user's shoe sole contacts and rolls against the universal ball head 20, the cleaning fluid on the surface of the ball head will be transferred to the sole, achieving uniform coating of the cleaning fluid.

[0040] This design avoids the waste caused by the large volume of liquid output in traditional direct-discharge systems. By using a quantitative transfer method through rolling friction, it improves the utilization rate of the cleaning fluid and extends the lifespan of consumables. Furthermore, the omnidirectional ball joint 20 automatically adjusts its rotation angle according to the direction of shoe sole movement, ensuring that the cleaning fluid can cover the concave areas of the complex tread pattern on the sole, further enhancing the uniformity and efficiency of the pre-cleaning effect.

[0041] Please refer to Figure 3 In some embodiments of this application, the scrubbing assembly includes a second motor 24, cleaning brush discs 7, and a rotating spindle 25. The second motor 24 is fixedly mounted on the bottom of the second mounting groove 5, and the output end of the second motor 24 is coaxially connected to the bottom end of the rotating spindle 25 via a coupling. Multiple cleaning brush discs 7 are evenly spaced along the axial extension direction of the rotating spindle 25, and each cleaning brush disc 7 is circumferentially fixedly connected to the rotating spindle 25 and can rotate synchronously with the spindle.

[0042] When the user enters the main cleaning area 3 and places both feet into the second mounting slot 5, the control system triggers the second motor 24 to start, driving the rotating spindle 25 to rotate at a constant speed. The cleaning brush disc 7 is made of highly elastic polyurethane sponge. Due to the elastic properties of the sponge material, the cleaning brush disc 7 will undergo adaptive deformation when it comes into contact with the sole of the shoe, allowing the bristles to penetrate deep into the recessed areas of the sole's texture (such as tire treads or mesh patterns).

[0043] Please refer to Figure 2 In some embodiments of this application, multiple cantilever brackets 8 are installed at the top of the second mounting groove 5 along its extending direction, and a cleaning brush 7 is disposed between two adjacent cantilever brackets 8, forming a structure in which brackets and brushes are arranged alternately. The cantilever brackets 8 are made of aluminum alloy. When cleaning the soles of shoes, the user can stand stably on the cantilever brackets 8, which provide reliable support and prevent the feet from dangling. At this time, the cleaning brush 7 located in the gaps between the brackets can rotate synchronously to clean the soles of the shoes in all directions. This design, through the staggered spatial arrangement of the brackets and brushes, ensures the stability of the user when standing and ensures that the brushes can fully contact the soles of the shoes, achieving synergistic optimization of support and cleaning functions, and improving the safety and comfort of the operation process.

[0044] The cleaning unit 1 is equipped with handrails 6 on both sides. The handrails 6 are made of stainless steel and covered with a non-slip layer. The height is adapted to the comfortable position for a person to hold naturally when standing. When cleaning the soles of shoes, the user can hold onto the handrails 6 with both hands. The support provided by the handrails 6 helps to maintain body stability and prevents wobbling due to pressure on the feet, thus improving safety and ease of operation during the cleaning process.

[0045] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
