[0002] In the process of cleaning shoes, a shoe washing machine needs to generate a large amount of foam to improve the cleaning effect. However, after the shoes are cleaned, the foam remains on the bottom surface and the bottom edge of the inner cover. Especially when the amount of detergent is large, the foam remains are particularly obvious. In order to dissipate the foam, the inner cover can be opened for a period of time to wait for the foam to dissipate automatically, or water flow can be used to flush, or a cloth can be used to wipe off the foam, etc. However, these methods are time-consuming and labor-intensive.

[0036] Based on the background technology, the existing shoe washing machine uses a spraying element to spray water flow, which cannot cover the entire inner cover bottom surface and bottom edge and cannot meet the multiple use requirements. The present application aims to solve the above problems by setting a first spraying port and a second spraying port on the bottom surface of the outer drum cover. The water flow sprayed from the first spraying port and the water flow sprayed from the second spraying port collide with each other on the inner cover bottom surface. After the collision, the water flow is distributed in a scattered point shape. Part of the water flow is dispersed in various directions on the inner cover bottom surface, and after washing the inner cover bottom surface, it falls into the inner drum. Part of the water flow is directly dispersed and sprayed into the inner drum. Therefore, when it is necessary to remove the foam on the inner cover bottom surface and the bottom edge, the water flow can cover the entire inner cover bottom surface. When it is necessary to wet the shoes and other articles in the inner drum, the water flow dispersed and sprayed into the inner drum can increase the wetting area. When it is necessary to defoam the foam in the inner drum, the water flow dispersed and sprayed into the inner drum can increase the defoaming speed. The defoaming coverage rate of the inner cover bottom surface and the bottom edge is improved, and other use requirements are also met.

[0037] The shoe washing machine of the present application comprises an outer drum, an inner drum and a cover assembly. The inner drum is rotatably arranged in the outer drum, and the cover assembly is arranged on the top side of the outer drum.

[0038] Referring to Figures 1-4 , Figure 1 FIG. 1 is a schematic view of the overall structure of the cover assembly of the present application, Figure 2 FIG. 2 is a schematic view of the bottom surface structure of the cover assembly of the present application, Figure 3 FIG. 3 is a schematic view of the top surface structure of the outer drum cover of the present application, Figure 4 FIG. 4 is a schematic view of the bottom surface structure of the outer drum cover of the present application. As Figures 1-4As shown, the cover assembly includes an outer bucket cover 1, an inner cover 2, a first cover plate 3, a second cover plate 4 and a water injection box 5. The top surface of the outer bucket cover 1 is provided with a mounting groove 11, and the bottom wall of the mounting groove 11 is provided with a drop opening 12. The bottom surface of the outer bucket cover 1 is provided with a first water groove 13, a second water groove 14, a first guide groove 15 and a second guide groove 16. The first water groove 13 and the second water groove 14 are arranged on the outer periphery of the mounting groove 11. The first guide groove 15 and the second guide groove 16 are arranged on the side wall of the drop opening 12 extending to the bottom side of the outer bucket cover 1. The side wall of the outer bucket cover 1 is provided with a water inlet 17. The inner cover 2 is arranged at the drop opening 12 and is used to open and close the drop opening 12. The bottom of the inner cover 2 is arranged in the mounting groove 11. The first cover plate 3 includes a first cover plate body 31 and a first guide portion 32. The first cover plate body 31 and the first water groove 13 form a first injection cavity. The first guide portion 32 and the first guide groove 15 form a first injection port. The first injection port is in communication with the first injection cavity. The second cover plate 4 includes a second cover plate body 41 and a second guide portion 42. The second cover plate body 41 and the second water groove 14 form a second injection cavity. The second guide portion 42 and the second guide groove 16 form a second injection port. The second injection port is in communication with the second injection cavity. The first injection port and the second injection port are arranged to enable the water flow injected from the first injection port and the water flow injected from the second injection port to collide with each other on the bottom surface of the inner cover 2. The water injection box 5 is arranged on the bottom surface of the outer bucket cover 1. The water injection box 5 forms a water injection cavity therein. The water injection cavity is in communication with the water inlet 17. The water injection cavity is in communication with the first injection cavity and the second injection cavity through water pipes.

[0039] Since the water flow injected from the first injection port and the water flow injected from the second injection port collide with each other on the bottom surface of the inner cover 2, the collided water flow is distributed in a scattered point shape. Part of the water flow is dispersed in various directions on the bottom surface of the inner cover 2, washes the bottom surface of the inner cover 2 and then falls into the inner bucket. Part of the water flow is directly dispersed and injected into the inner bucket. Therefore, when it is necessary to remove the foam on the bottom surface and the bottom edge of the inner cover 2, the water flow can cover the entire bottom surface of the inner cover 2. When it is necessary to wet the articles such as shoes in the inner bucket, the water flow dispersed and injected into the inner bucket can increase the wetting area. When it is necessary to defoam the foam in the inner bucket, the water flow dispersed and injected into the inner bucket can increase the defoaming speed. The defoaming coverage rate of the bottom surface and the bottom edge of the inner cover 2 is improved, and other use requirements are also met.

[0040] The arrangement of the first injection cavity and the second injection cavity enables the water flow to gather in the injection cavity and then flow out of the injection port, which can increase the water pressure of the water flow and effectively improve the defoaming and wetting effects. The water groove and the cover plate body form the injection cavity. The water groove is directly arranged on the bottom surface of the outer bucket cover 1 and is part of the outer bucket cover. The space on the bottom surface of the outer bucket cover 1 is fully utilized, the structure is simplified, and the space is saved.

[0041] It can be understood by those skilled in the art that, although it is described above that the first spray cavity is formed by the first water tank 13 and the first cover plate body 31, and the second spray cavity is formed by the second water tank 14 and the second cover plate body 41, this is not restrictive, and the first water spray box and the second water spray box can also be provided on the bottom surface of the outer tub cover 1, the first spray cavity is formed in the first water spray box, and the second spray cavity is formed in the second water spray box. In addition, although it is described above that the first spray port is formed by the first guide groove 15 and the first guide portion 32, and the second spray port is formed by the second guide groove 16 and the second guide portion 42, this is also not restrictive, and the first spray pipe and the second spray pipe can also be provided on the bottom surface of the outer tub cover 1, the first spray port is formed in the first spray pipe, and the second spray port is formed in the second spray pipe.

[0042] It should be noted that the first cover plate body 31 can be provided separately from the outer tub cover 1, and the first cover plate body 31 is bolted or adhesively fixed to the outer tub cover 1, or the first cover plate body 31 can be integrally formed with the outer tub cover 1, as long as the first spray cavity can be formed; the second cover plate body 41 can be provided separately from the outer tub cover 1, and the second cover plate body 41 is bolted or adhesively fixed to the outer tub cover 1, or the second cover plate body 41 can be integrally formed with the outer tub cover 1, as long as the second spray cavity can be formed. The first guide portion 32 can be provided separately from the outer tub cover 1, connected with the first cover plate body 31, or directly bolted or adhesively fixed to the outer tub cover 1, or the first guide portion 32 can be integrally formed with the outer tub cover 1, as long as the first spray port can be formed; the second guide portion 42 can be provided separately from the outer tub cover 1, connected with the second cover plate body 41, or directly bolted or adhesively fixed to the outer tub cover 1, or the second guide portion 42 can be integrally formed with the outer tub cover 1, as long as the second spray port can be formed.

[0043] Regarding the number of the first spray ports and the second spray ports, one or multiple can be provided, when multiple first spray ports are provided, the opening directions of the first spray ports can be different, and when multiple second spray ports are provided, the opening directions of the second spray ports can be different, so that the first spray ports and / or the second spray ports can simultaneously spray water flow in different directions, and more dispersed water flow in more directions can be generated when colliding, which effectively increases the coverage of the water flow on the bottom surface of the inner cover 2, and improves the defoaming efficiency of the water flow on the foam in the inner tub and the wetting efficiency of the water flow on the articles in the inner tub. Alternatively, the first spray cavity and the second spray cavity can be symmetrically provided, and the first spray ports and the second spray ports can be symmetrically provided one by one, so that the water flow sprayed by the first spray ports and the second spray ports can better collide with each other, thereby obtaining more dispersed water flow.

[0044] Specifically, the first guide part 32 and the second guide part 42 can be a planar plate structure or a groove structure. When the first guide part 32 is a groove structure, the two side walls of the first guide part 32 are arranged in the first guide groove 15. When the second guide part 42 is a groove structure, the two side walls of the second guide part 42 are arranged in the second guide groove 16. The shape, length, and opening direction of the first guide part 32 and the second guide part 42 can be adjusted as needed.

[0045] Those skilled in the art can understand that, although the above describes that the top surface of the outer bucket cover 1 is provided with the mounting groove 11, the bottom wall of the mounting groove 11 is provided with the drop opening 12, the drop opening 12 is used to take and place shoes or other articles that need to be washed, the inner cover 2 is arranged in the mounting groove 11, and when the water and foam of the inner bucket and the water sprayed by the spray opening move upward from the drop opening 12, part of the water and foam is directly dropped into the inner bucket after being vertically blocked by the inner cover 2, and part of the water and foam overflows from the gap between the inner cover 2 and the bottom wall of the mounting groove 11 and is blocked by the side wall of the mounting groove 11, so that the water and foam cannot continue to overflow upward and return to the inner bucket, thereby effectively preventing the water and foam from overflowing from the drop opening 12; however, this is not a limitation, and the bottom of the inner cover 2 can also pass through the drop opening 12, and part of the bottom of the inner cover 2 is arranged on the bottom side of the drop opening 12; the mounting groove 11 can also not be arranged on the outer bucket cover 1, and the drop opening 12 is directly arranged on the outer bucket cover 1, and the inner cover 2 is arranged on the top side of the outer bucket cover 1 or the bottom of the inner cover 2 passes through the drop opening 12 and is arranged on the bottom side of the drop opening 12, as long as the water and foam can be prevented from overflowing from the drop opening 12. Those skilled in the art can adjust as needed, and the above adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0046] In addition, although the above describes that the water inlet 17 is arranged on the side wall of the outer bucket cover 1 and the water injection box 5 is arranged on the bottom surface of the outer bucket cover 1, this is also not a limitation, and the water inlet 17 can also be arranged on the top wall or the bottom wall of the outer bucket cover 1, and the water inlet 17 can also be directly arranged on the water injection box, as long as the water inlet 17 can be communicated with the water injection cavity, and water can enter the water injection cavity from the water inlet 17; the water injection box 5 can also be arranged on the top surface or the outer periphery of the outer bucket cover 1, as long as the water injection cavity can be communicated with the water inlet 17, the first spray cavity, and the second spray cavity, respectively. Possibly, a water pipe joint can also be arranged at the water inlet 17, which is used to facilitate the quick connection of the water inlet pipe, and water is introduced into the water injection cavity through the water inlet pipe; a water pipe joint can also be arranged on the water injection box 5, and a water pipe is connected with the water pipe joint, thereby facilitating the connection and arrangement of the water pipe; the water injection box 5 can be fixed to the outer bucket cover 1 by screw connection or can be fixed to the outer bucket cover 1 by a clamping structure.

[0047] Furthermore, although it is described above that the first guide groove 15 and the second guide groove 16 are arranged on the side wall of the outer bucket cover 1 extending to the bottom side of the pouring port 12, this is not restrictive, and the first guide groove 15 and the second guide groove 16 can also be arranged on the side wall of the mounting groove 11, as long as the water flow in the spray cavity can be guided to the bottom surface of the inner cover 2.

[0048] Possibly, the inner cover 2 is hingedly connected with the outer bucket cover 1 through a pin shaft, facilitating the opening and closing of the inner cover 2, when the inner cover 2 is closed, the water or foam in the inner bucket can be prevented from overflowing, and when the inner cover 2 is opened, the articles can be taken out from the pouring port. A handle can be arranged on the inner cover 2 for facilitating the opening of the inner cover 2. In addition, a sealing ring can be arranged between the inner cover 2 and the bottom wall of the mounting groove 11, the sealing ring can be integrally injection molded or adhesively fixed with the inner cover 2 or with the bottom wall of the mounting groove 11, further improving the waterproof sealing effect of the inner cover 2.
