The existing shoe washing machines on the market are mainly divided into vertical shoe washing machines and drum shoe washing machines. Among them, the drum shoe washing machines generally have the following problems:

[0003] 1. At present, the brushes installed between every two lifting ribs in the inner barrel of the drum shoe washing machine are generally assembled or disassembled integrally, and the brushes cannot be disassembled individually. Therefore, when the brushes are damaged and need to be replaced in the later stage, the whole needs to be disassembled and reassembled, and the whole process is rather troublesome.

[0004] 2. Since the lifting ribs on the inner barrel wall of the drum shoe washing machine are made of convex plastic materials, the inner wall of the inner barrel cannot achieve the effect of full brushes, resulting in a poor cleaning effect when washing the shoes. At the same time, due to the material problem of the lifting ribs, the shoes will come into contact with the lifting ribs, causing damage to the surface of the shoes.

[0005] 3. The opening of the barrel of the existing drum shoe washing machine is relatively large, while the observation window on the sealing door body is relatively small. After the sealing door body is completely closed, there is a large gap between the barrel and the observation window, which easily causes the shoes to be stuck in this gap when lifted, and then when other shoes push the stuck shoes, it will cause wear to the shoes.

[0034] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification. Embodiment

[0035] As Figure 1-8As shown in the figure, the utility model provides a shoe washing machine, which includes a machine shell 1. A pick-up and placement opening 2 is provided on the front end face of the machine shell 1. An outer barrel 3 is arranged in the inner cavity of the machine shell 1, and an inner barrel 4 is arranged in the inner cavity of the outer barrel 3. The barrel opening of the inner barrel 4 corresponds to the pick-up and placement opening 2. A plurality of brush plates 5 are fixedly installed on the inner wall of the inner barrel 4 along the circumferential direction. At least one lifting brush plate 6 is arranged between the plurality of brush plates 5 along the circumferential direction of the inner wall of the inner barrel 4. The length of the brush on the lifting brush plate 6 is higher than that of the brush on the brush plate 5. A retaining ring 7 is fixedly connected to the outside of the barrel opening of the inner barrel 4. A closed opening 71 is provided on one side of the retaining ring 7 close to the barrel opening of the inner barrel 4. A rubber sealing ring 8 is arranged on the side of the retaining ring 7 away from the inner barrel 4. The rubber sealing ring 8 is arranged in the pick-up and placement opening 2. A door body 9 for blocking the pick-up and placement opening 2 is hinged on the front end face of the machine shell 1. An observation window 10 is connected to the door body 9. One end of the observation window 10 away from the door body 9 is adapted to the inside of the closed opening 71.

[0036] Specifically, when the brush plates 5 and the lifting brush plate 6 are assembled along the inner wall of the inner barrel 4, it is not limited to the illustrated state. The best setting state of the two is a total of twelve pieces. Specifically, nine brush plates 5 are provided, and three lifting brush plates 6 are provided and inserted between the nine brush plates 5. The assembly interval between adjacent brush plates 5 or between the brush plate 5 and the lifting brush plate 6 is 1 mm. The specific effect is to increase the area of the brush plates 5 and the lifting brush plate 6, so as to reduce the number of brush plates 5 and facilitate the rapid assembly of the brushes on the inner wall of the inner barrel 4. It should be emphasized that while reducing the number of brush plates 5, the first threaded holes 14 on the inner barrel 4 are also correspondingly reduced, thereby effectively reducing the opening process.

[0037] Furthermore, when the brush plates 5 and the lifting brush plate 6 are fixedly installed along the inner wall of the inner barrel 4, the front ends of the brush plates 5 and the lifting brush plate 6 are spaced a certain distance from the barrel opening of the inner barrel 4, and the rear ends of the brush plates 5 and the lifting brush plate 6 are also spaced a certain distance from the inner bottom wall of the inner barrel 4. The above-mentioned spacing distance values are both 3 - 5 cm. By adopting this spacing design, the problem of drainage of the inner barrel 4 is effectively guaranteed.

[0038] Combined Figure 7 and Figure 8 As shown in the figure, in this embodiment, two groups of annular tracks 11 are fixedly installed on the inner wall of the inner barrel 4. Arc-shaped grooves 12 are respectively formed on the surfaces of the brush plates 5 and the lifting brush plate 6. The inner wall of the arc-shaped groove 12 is adapted to the outer wall of the annular track 11. The brush plates 5 and the lifting brush plate 6 are clamped on the annular track 11 through the arc-shaped grooves 12. A plurality of second stepped holes 15 are evenly formed on the surface of the annular track 11 along the circumferential direction. A plurality of second threaded holes 16 corresponding to the second stepped holes 15 are evenly formed on the surface of the inner barrel 4 along the circumferential direction.

[0039] Further, each group of annular tracks 11 includes two annular tracks 11, and the four annular tracks 11 are respectively fixedly installed on the inner barrel 4 by existing screws passing through the second stepped holes 15 to ensure the stability of the four annular tracks 11. With the design of the four annular tracks 11, after the multiple brush plates 5 and the lifting brush plates 6 are installed and fixed, the effect of preventing deviation can be achieved. At the same time, the multiple brush plates 5 and the lifting brush plates 6 are closely attached, enabling the inner wall of the inner barrel 4 to achieve the effect of being fully brushed, improving the cleaning degree of the shoes. Moreover, the close attachment of the multiple brush plates 5 and the lifting brush plates 6 can further ensure the stability of the brush plates 5 and the lifting brush plates 6. It should be noted that according to the above requirements, the existing screws can be flat-headed stainless steel screws.

[0040] Combined with Figure 7 and Figure 8 As shown, furthermore, a plurality of positioning grooves are formed on the surface of the annular track 11 along the circumferential direction, and positioning blocks adapted to the positioning grooves are arranged in the arc-shaped grooves 12. Specifically, positioning blocks are arranged in the arc-shaped grooves 12 on the surfaces of the brush plates 5 and the lifting brush plates 6. Then, by the adaptation of the positioning grooves and the positioning blocks, after the brush plate 5 or the lifting brush plate 6 is placed, the positioning block can be positioned in the positioning groove, ensuring that the first stepped hole 13 can directly correspond to the first threaded hole 14 and improving the assembly efficiency.

[0041] Combined with Figure 7 As shown, in this embodiment, the longitudinal section of the annular track 11 is a set of opposite rectangles, semi-circles or trapezoids.

[0042] Further, in this solution, the schematic diagram of the longitudinal section of the annular track 11 is a rectangle, but in actual use, the longitudinal section of the annular track 11 is not limited to the rectangular state and can be a semi-circle or a trapezoid. Accordingly, the notch of the arc-shaped groove 12 adapted thereto can be a semi-circular notch and a trapezoidal notch to ensure that the brush plate 5 and the lifting brush plate 6 are closely attached to the annular track 11 and ensure that the annular track 11 plays a limiting role on the brush plate 5 and the lifting brush plate 6.

[0043] Combined with Figure 3 and Figure 6 As shown, in this embodiment, the inner diameter of the closed port 71 is smaller than the inner diameter of the inner barrel 4, and a blocking area is formed between the inner wall of the closed port 71 and the inner wall of the inner barrel 4, and the height of the blocking area is greater than the height of the lifting brush plate 6.

[0044] Further, from Figure 3When directly viewing the inner barrel 4 from the front view shown, the brushes on the brush plate 5 and the lifting brush plate 6 can be blocked by the retaining ring 7 and thus cannot be seen. Through the design of the retaining ring 7, the opening of the inner barrel 4 is reduced. After the door body 9 is completely closed, the end of the observation window 10 far from the door body 9 can be adapted to the inner ring side of the closed port 71, and at the same time, one side of the observation window 10 can be flush with one side of the retaining ring 7, ensuring that there is no gap between the observation window 10 and the inner barrel 4. Therefore, the problem that there is a large gap between the barrel body and the observation window 10 in the existing drum-type shoe washing machine after the door body 9 is completely closed and it is easy to get the shoe body stuck is avoided, and further the problem of effectively avoiding wear on the shoe body is solved.

[0045] Combined with Figure 7 As shown, in this embodiment, first stepped holes 13 are respectively opened at both ends of the lifting brush plate 6 and the plurality of brush plates 5, and at least two first stepped holes 13 are provided at each end of the brush plate 5 and the lifting brush plate 6. A plurality of first threaded holes 14 are penetrated through the outer wall of the inner barrel 4 in the circumferential direction, and the plurality of first threaded holes 14 respectively correspond to the plurality of first stepped holes 13.

[0046] Furthermore, the first stepped hole 13 is a countersunk hole, and by designing at least two first stepped holes 13 at each end of the brush plate 5 and the lifting brush plate 6, after the brush plate 5 and the lifting brush plate 6 are fixedly installed on the inner barrel 4 by existing screws, the installation stability of the brush plate 5 and the lifting brush plate 6 can be ensured, which is convenient for use. It should be noted according to the above that existing screws can be flat-headed stainless steel screws.

[0047] Combined with Figure 2 、 Figure 3 and Figure 5 As shown, in this embodiment, a stepped area is formed on the inner sides of the retaining ring 7 and the rubber sealing ring 8, and the outer surface of the observation window 10 is adapted to the stepped area.

[0048] Furthermore, the overall shape of the observation window 10 is similar to a "bowl" shape. The front part with a larger diameter can be adapted to the inner diameter of the rubber sealing ring 8, and the rear part with a smaller diameter can be adapted to the inner ring side of the retaining ring 7. In this way, when the opening of the barrel mouth becomes smaller after the inner barrel 4 is connected to the retaining ring 7, the shape of the observation window 10 can be completely adapted to the connected retaining ring 7, ensuring that there is no gap between the observation window 10 and the inner barrel 4 after the door body 9 is completely closed, and avoiding the problem of getting the shoe body stuck and causing wear to the shoe body in the existing drum-type shoe washing machine.

[0049] Combined with Figure 8 As shown, in this embodiment, a plurality of drain holes are respectively penetrated through the surfaces of the brush plate 5 and the lifting brush plate 6, and the plurality of drain holes are arranged in a staggered manner with the brushes on the brush plate 5 and the lifting brush plate 6. By designing a number of drain holes, when the shoe washing machine drains water, the discharge of water source can be effectively ensured.

[0050] In this embodiment, a control area 17 is provided at the top of the front end face of the casing 1, and the control buttons in the control area 17 facilitate the setting and starting of the shoe washing machine.

[0051] The working principle and usage process of the present utility model are as follows:

[0052] Before use, a plurality of annular tracks 11 are fixedly installed on the inner wall of the inner barrel 4 through existing screws, and a plurality of brush plates 5 and lifting brush plates 6 are fixedly installed on the inner wall of the inner barrel 4 along the circumferential direction of the inner barrel 4. During this period, the plurality of brush plates 5 and lifting brush plates 6 are respectively clamped on the annular tracks 11 through the arc-shaped grooves 12, effectively ensuring the stability of the brush plates 5 and lifting brush plates 6 after installation. Then, a retaining ring 7 is fixedly connected to the mouth side of the inner barrel 4, making the opening of the mouth of the inner barrel 4 smaller. At the same time, the observation window 10 on the door body 9 is processed into a "bowl" shape, so that one end of the observation window 10 can be adapted to the closed port 71.

[0053] During use, the shoe washing machine is assembled according to the structure before use. When assembling and using, the shoe body is placed into the inner barrel 4 through the access opening 2, and then the door body 9 is closed. After the door body 9 is closed, the outer wall of the observation window 10 can closely fit the stepped area formed by the retaining ring 7 and the inner side of the rubber sealing ring 8. At the same time, one end of the observation window 10 away from the door body 9 can be adapted to the inner ring side of the closed port 71, so that the side of the observation window 10 away from the door body 9 can be flush with one side of the retaining ring 7, ensuring that there is no gap between the observation window 10 and the inner barrel 4. In this way, when the shoe washing machine is working, the problem of the shoe body being stuck and worn is effectively avoided; at the same time, when the shoe body rotates in the inner barrel 4, since the length of the bristles on the lifting brush plate 6 is higher than the length of the bristles on the brush plate 5, the lifting brush plate 6 can be used to lift the shoe body, effectively avoiding the problem of the existing lifting ribs damaging the shoe body. At the same time, due to the installation of a plurality of brush plates 5 and lifting brush plates 6 on the inner wall of the inner barrel 4, the inner wall of the inner barrel 4 achieves the effect of being fully covered with bristles, effectively improving the cleaning of the bristles on the shoe body.

[0054] When replacing the bristles, since a plurality of individual brush plates 5 and lifting brush plates 6 are fixedly installed on the inner wall of the inner barrel 4, when replacing the bristles, only the damaged brush plates 5 and lifting brush plates 6 need to be disassembled, replaced, and assembled, effectively improving the efficiency of bristle replacement.

[0055] It should be emphasized that this solution only focuses on the structural improvement of the inner barrel 4, the inner wall of the inner barrel 4, and the observation window 10, and does not improve other areas of the drum-type shoe washing machine. Therefore, although other driving devices are not mentioned in this solution, the driving device is a publicly known technology. After cooperating with the technical improvements proposed in this solution, the normal operation of the shoe washing machine can be fully achieved.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or instance. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0057] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
