Description

Technical Field

[0001] This utility model relates to a shoe washing machine, and more particularly to an inner cylinder device for forming the internal cleaning chamber of the shoe washing machine. Background Technology

[0002] Shoe washing machines are used to clean shoes. The inner circumference of the machine's inner cylinder has several inward-extending bristles with a certain degree of stiffness, used to scrub the shoe surface. The outer ends of the bristles are used to directly scrape the surface of items to be cleaned, removing dirt. In existing shoe washing machines, the bristles are inserted in tufts into mounting holes on the front of the cleaning component. This requires a bristle-planting machine, a relatively complex process, and also results in bristle shedding during operation.

[0003] Chinese patent document (publication number: CN 220675956U) discloses an inner tub and a shoe washing machine, which includes a first ring seat, a second ring seat, and a cleaning plate with bristles disposed between the first ring seat and the second ring seat. Multiple cleaning plates are arranged sequentially along the circumference of the first ring seat, and all the cleaning plates enclose a cleaning cavity. This application can improve the installation efficiency of the shoe washing machine.

[0004] The inner cylinder of this shoe washing machine is mainly composed of several cleaning plates with bristles. The bristles need to be inserted into several mounting holes formed on the surface of the cleaning plates, which also brings about the aforementioned problems. In addition, when assembling the inner cylinder, both ends of the cleaning plates need to be installed onto two ring seats, making the assembly process rather cumbersome. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an inner cylinder device for a shoe washing machine. This inner cylinder device is easy to manufacture and is less prone to shedding during operation.

[0006] To solve the aforementioned technical problem, the present invention provides the following technical solution: an inner cylinder device for a shoe washing machine, comprising a hollow cylindrical body with a cleaning chamber formed within it. The inner wall of the body is provided with a plurality of bristles extending into the cleaning chamber, the bristles being perpendicular or approximately perpendicular to the inner wall. The body comprises a plurality of front panels and back panels, the back panels having a higher hardness than the front panels. The front panels are adhered and fixed to the inner surface of the back panels, and the back panels provide support for the front panels. The front panels are made of soft plastic, the bristles are single columnar bodies, and the bristles and the panel are integrally formed from the same material, with the bristles formed on the front side of the front panel.

[0007] Both the front panel and back panel are typically made of plastic. The front panel can be made of TPE, while the back panel can be made of PP. Their physical properties differ; the back panel is harder than the front panel. The spatial shape of the front panel is determined by the back panel. After assembly, the bristles are usually perpendicular to the inner wall of the cleaning chamber, although a slight angle at the bristles is not excluded. Each bristle is a single unit, unlike existing structures where multiple bristles are tufted together and installed in a single mounting hole. The front panel and back panel are attached and fixed together using adhesive or several of the following mating structures. While the front panel and back panel can be a single, integral structure, they are usually composed of multiple pieces, which are then joined together to form a cylindrical structure.

[0008] Furthermore, several protrusions are provided on the inner surface of the back panel, and several fixing holes are provided on the panel to elastically fit onto the outer peripheral surface of the protrusions. Through the cooperation of these protrusions and fixing holes, the back panel can be well adapted to fix and support the panel.

[0009] Furthermore, through holes are provided at the axial position of the protrusion, and these through holes can be used to achieve water permeability.

[0010] Furthermore, the bristles are arranged in several rows along the axial direction of the inner wall of the body, with adjacent rows of bristles spaced apart circumferentially, and the protrusion is disposed within the interval. This ensures that the bristles are not affected when fixing holes are provided on the panel.

[0011] Furthermore, the back panel consists of multiple pieces, with adjacent back panels having their close side edges snapped together using a snap-fit ​​structure. Multiple back panels are joined together to form a cylindrical shape. Typically, the front panel also consists of multiple pieces, which facilitates the fabrication of the back panel.

[0012] Furthermore, the front panel and back panel each consist of three pieces: two large-area back panels and one small-area back panel. The two large-area back panels have equal areas, but the area of ​​the large-area back panel is larger than that of the small-area back panel. The areas of the front panel and the back panel they belong to correspond. The inner cylinder body is constructed by splicing these front and back panels together. This ensures that the inner cylinder meets the strength requirements while also facilitating its fabrication and reducing manufacturing costs.

[0013] Furthermore, L-shaped, opposing tongue-and-groove joints are formed at the adjacent side edges of two adjacent back plates. One tongue-and-groove joint has a insertion hole on its bottom surface, and the other tongue-and-groove joint has a corresponding plug inserted into the insertion hole on its bottom surface. The outer end of the plug has a barb. This snap-fit ​​structure facilitates the molding of the body, resulting in a simple structure and high strength after molding.

[0014] Furthermore, the back plate is provided with several mounting holes, and a retaining ring is formed protruding on the back of the panel to be inserted into the mounting device hole. This further improves the connection strength of the panel to the back plate, resulting in good connection stability of the panel to the back plate.

[0015] Furthermore, the outer edge of the outer opening of the fixing ring extends to the outer surface of the back plate. An annular groove is formed on the outer circumferential surface of the outer opening of the fixing ring, and the opening of the mounting port is inserted into the annular groove, resulting in high connection stability between the fixing ring and the back plate.

[0016] Furthermore, an extension piece is integrally formed on the back panel at the position corresponding to the mounting opening. The extension piece extends into the mounting opening, and a protrusion is integrally formed at the outer end of the extension piece. A hollow convex cap is provided on the panel at the position corresponding to the protrusion, with the convex cap and brush bristles located on the same side of the panel. The convex cap elastically fits onto the protrusion. Through the structure of the extension piece, the space of the mounting opening can be effectively utilized, further improving the connection stability of the panel on the back panel.

[0017] Compared with existing technologies, this invention offers the following advantages: By integrally molding the bristles onto the panel, there is no need to implant tufts of bristles into the corresponding cleaning structure, simplifying the manufacturing process and effectively reducing production costs. Furthermore, during the shoe washing machine's operation, there is no shedding of bristles, and the likelihood of fallen bristles clogging the water outlet inside the machine is reduced. During assembly, the panel is directly attached and fixed to the back panel, making installation convenient and quick. Attached Figure Description

[0021] Referring to the accompanying drawings, this inner cylinder device is installed inside the shoe washing machine to form a cylindrical cleaning chamber within the machine.

[0022] The inner cylinder device comprises a hollow cylindrical body 1, which is vertically positioned within the shoe washing machine. A cleaning chamber is formed within the body 1, into which shoes to be cleaned are placed. Several bristles 4 extend into the cleaning chamber from the inner wall of the body 1, perpendicular or approximately perpendicular to the inner wall. During operation, the ends of the bristles 4 contact and scrape the surface of the shoes. The body 1 has a split structure, comprising several panel 3 and a back plate 2. The back plate 2 is made of soft, translucent plastic, while the back plate 2 is made of a hard plastic with a certain degree of rigidity. The back plate 2 has a certain degree of flexibility, allowing it to curl to a certain extent; the strength of the back plate 2 primarily determines the overall strength of the inner cylinder. The panel 3 is fitted and fixed to the inner surface of the back plate 2, adapting to the orientation of the inner surface of the back plate 2, and the back plate 2 provides support for the panel 3. Multiple panels 3 can be mounted on a single backplate 2, but typically, one panel 3 is attached and fixed to the inner surface of a backplate 2. The area of ​​panel 3 is generally slightly smaller than the area of ​​the backplate 2, but the area of ​​panel 3 cannot be larger than the area of ​​the backplate 2. That is, when panel 3 is assembled onto backplate 2, panel 3 cannot protrude beyond the outer edge of the backplate 2; otherwise, backplate 2 cannot provide full support for panel 3. The bristles 4 and the panel 3 are integrally molded from the same material, usually by molding. The bristles 4 are single columnar bodies, formed on the front side of panel 3, and are generally perpendicular to the front side of panel 3, extending into the cleaning chamber.

[0023] The panel 3 and the back plate 2 are generally connected and fitted through a snap-fit ​​structure. After the panel 3 is pressed flat on the inner surface of the back plate 2, since there is essentially no air between the panel 3 and the back plate 2, the panel 3 also has a certain degree of adhesion to the back plate 2. In addition, during operation, cleaning water is pressed onto the panel 3, and the stability of the panel 3 on the back plate 2 usually meets the usage requirements. Several protrusions 9 are provided on the inner surface of the back plate 2, and several fixing holes 10 are provided on the panel 3, which elastically fit onto the outer circumference of the protrusions 9. That is, there is a certain degree of tightness between the fixing holes 10 and the protrusions 9, so that the panel 3 can have good connection and firmness on the back plate 2. The number of protrusions 9 is generally required to provide a large number of connection and fixing points between the panel 3 and the back plate 2. A through hole is provided at the axis position of the protrusion 9, allowing cleaning water to pass between the inside and outside of the inner cylinder through the through hole. The arrangement density of the bristles 4 on the panel 3 meets the general requirements of the shoe washing machine industry. However, in one embodiment, the bristles 4 are not arranged over the entire area of ​​the panel 3. As shown in the figure, the bristles 4 are arranged in several rows along the axial direction of the inner wall of the body 1. Adjacent rows of bristles 4 are spaced apart in the circumferential direction of the body 1. The protrusions 9 and fixing holes 10 are both disposed within the interval.

[0024] The main body 1 is not a single, integral structure. In practical applications, the back plate 2 consists of multiple pieces. The adjacent side edges of two back plates 2 are snapped together by a snap-fit ​​structure, thus forming the main spatial shape of the main body 1. As shown in the diagram, the panel 3 and the back plate 2 each consist of three pieces. The back plate 2 is divided into two large-area back plates 22 and one small-area back plate 21. The two large-area back plates 22 have equal areas, but the area of ​​the large-area back plate 22 is larger than that of the small-area back plate 21. The area of ​​the small-area back plate 21 is approximately 1 / 4 to 1 / 3 of the area of ​​the large-area back plate 22. A panel 3 is attached and fixed to one of the back plates 2, with the panel 3 corresponding to the area of ​​the back plate 2 it is on. This panel 3 is typically located on the back side of the small-area back plate 21, where wires pass through. The panel 3 is generally equal to or slightly smaller in area than the back panel 2, but there are no special requirements for the specific difference in area between them. Usually, when the panel 3 is attached to the middle of the inner surface of the corresponding back panel 2, the blank width on the outside of the panel 3 on the back panel 2 is generally about one centimeter.

[0025] To facilitate the connection between two adjacent back panels 2, L-shaped tongues and grooves 8 are formed at the adjacent side edges of the two adjacent back panels 2, extending along the entire height of the back panel 2. Two corresponding tongues and grooves 8 are placed opposite each other. One tongue and groove 8 has a socket 82 on its bottom surface, and the other tongue and groove 8 has a plug 81 that is inserted into the socket 82 on its bottom surface. The outer end of the plug 81 has a barb. As shown in the figure, the socket 82 and the plug 81 are arranged in pairs.

[0026] The back plate 2 has several mounting openings 7, the size of which is much larger than the outer diameter of the aforementioned protrusion 9. The mounting openings 7 penetrate the thickness of the back plate 2, and a retaining ring 31 is formed protruding on the back of the panel 3, which is inserted into the mounting hole. The retaining ring 31 is integrally formed on the back of the panel 3, and the panel 3 is not transparent at the position of the retaining ring 31, making the retaining ring 31 a blind pit structure. In order to improve the connection between the retaining ring 31 and the mounting opening 7, the outer edge of the outer opening of the retaining ring 31 extends outward to the outer surface of the back plate 2, and the retaining ring 31 wraps around the opening of the mounting opening 7.

[0027] An extended piece 5 is integrally formed on the back plate 2 at the position corresponding to the mounting opening 7. Typically, one extended piece 5 is provided for each mounting opening 7, but it is not necessary to provide one extended piece 5 at every mounting opening 7. The extended piece 5 extends into the mounting opening 7. A protruding post 6 is integrally formed at the outer end of the extended piece 5. A hollow protruding cap 11 is provided on the panel 3 at the position corresponding to the protruding post 6. The protruding cap 11 and the brush bristles 4 are located on the same side of the panel 3, and the protruding cap 11 is generally positioned at the position of the brush bristles 4. The inner end of the protruding cap 11 is open, and the outer end is closed. The protruding cap 11 elastically fits onto the protruding post 6. The provision of the protruding post 6 can also effectively compensate for the insufficient number of protrusions 9 on the small-area back plate 21, thereby increasing the number of connection points of the corresponding panel 3 on the small-area back plate 21.
