[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0034] One embodiment of this utility model provides an automatic shoe washing machine, such as... Figures 1 to 8 As shown, the automatic shoe washing machine includes a washing chamber 1, a washing assembly, a drive assembly, and a storage assembly.

[0035] Specifically, the washing assembly is located inside the washing chamber 1 and includes a robotic arm 2, a first motor 3, and a brush 4. The first motor 3 is connected to the first end of the robotic arm 2. The output shaft of the first motor 3 is detachably connected to the connection part 13 formed by the lower end of the brush 4. The first motor 3 can drive the brush 4 to rotate, thereby cleaning the shoes. The first motor 3 and the brush 4 can be flexibly disassembled and assembled so that the brush 4 can be replaced. The drive assembly is connected to the second end of the robotic arm 2 and is used to drive the first end of the robotic arm 2 to move up and down and swing left and right, so that the brush 4 on the first motor 3 can move in space and clean various parts of the shoes.

[0036] Furthermore, the storage assembly includes a replacement box 5 and a second motor (not shown in the figure). An opening 6 is formed on the side wall of the washing chamber 1. The replacement box 5 is disposed at the opening 6. The second motor is used to drive the replacement box 5 to rotate within the opening 6. At least two fixing parts are provided around the rotation center of the replacement box 5. The fixing parts are used to accommodate and fix the brush 4, that is, each fixing part can accommodate and fix one brush 4. When the first motor 3 and one of the fixing parts are both moved to the replacement position, the brush 4 on the first motor 3 is inserted into the fixing part. The second motor can drive different fixing parts to rotate and move to the replacement position.

[0037] The steps for replacing the brushes in the automatic shoe washing machine in this embodiment are as follows:

[0038] First, such as Figure 1 As shown, the second motor drives the replacement box 5 to rotate, moving the empty fixing part to the replacement position; next, the drive assembly drives the first motor 3 to move to the replacement position, at which point the currently used brush 4 on the first motor 3 is inserted into the empty fixing part, and the first motor 3 is separated from the currently used brush 4; then, the drive assembly drives the first motor 3 away from the replacement position, placing the currently used brush 4 on the fixing part, as shown. Figure 2 As shown, the second motor drives the replacement box 5 to rotate again, causing the fixing part containing the brush 4 to be replaced to move to the replacement position; then, the drive assembly drives the first motor 3 to move to the replacement position, so that the first motor 3 is connected to the brush 4 to be replaced; finally, the drive assembly drives the first motor 3 to leave the replacement position, thus completing the replacement of the brush 4.

[0039] This automatic shoe washing machine features replaceable brushes to handle different cleaning processes. From the moment shoes are placed in the machine until a pair of dry shoes emerges, no manual operation is required, completely freeing up users' hands and making it more convenient and efficient. For example, when dry cleaning shoes, a stiffer brush can be used to brush the shoes first, then a softer brush can be used to wipe away any remaining foam. This automatic shoe washing machine can also be used for shoe care. For instance, when caring for leather shoes, a stiffer brush can be used to remove dust, then a softer brush can be used to apply shoe polish. Finally, the brush rotates at high speed to polish the shoes.

[0040] In summary, in the automatic shoe washing machine of this embodiment, by setting a first motor that can move up and down and swing left and right, and the output shaft of the first motor is detachably connected to the brush, and by setting a replacement box that can accommodate and fix the brush and can rotate, the first motor can place the brush in use into the replacement box and obtain the brush to be used in the replacement box, thereby realizing automatic brush replacement, which is more convenient to use and provides a better user experience.

[0041] In this embodiment, as Figure 7 and Figure 8As shown, the scrubbing assembly also includes a rotary joint 7.

[0042] The rotary joint 7 is fixed on the output shaft of the first motor 3. The upper end of the rotary joint 7 has an external thread, and the lower end of the connecting part 13 has an internal thread that mates with the external thread. In this way, by rotating the first motor 3 in the forward direction, the rotary joint 7 can be screwed into the brush 4 to connect the first motor 3 and the brush 4. By rotating the first motor 3 in the reverse direction, the rotary joint 7 can be screwed out of the brush 4 to separate the first motor 3 and the brush 4, thus making the connection and separation of the first motor 3 and the brush 4 more convenient.

[0043] It should be noted that when the first motor 3 is connected to the brush 4, the first motor 3 rotates in the forward direction and moves upward; when the first motor 3 is separated from the brush 4, the first motor 3 rotates in the reverse direction and moves downward, ensuring that the brush 4 remains stationary within the fixed part, making it easier for the first motor 3 and the brush 4 to connect and separate.

[0044] Of course, the output shaft of the first motor can also be detachably connected to the connecting part on the brush through a snap-lock structure, or the motor and the brush can be detachably connected through a strong magnetic attraction structure, all of which are within the protection scope of this utility model.

[0045] In other embodiments, the replacement box rotates vertically, meaning the axis of rotation of the replacement box is horizontal. Fixing parts are provided on both sides of the rotation center of the replacement box, meaning the replacement box has two fixing parts. One of the two fixing parts can be used to hold and fix the brush in use, and the other can be used to hold and fix the brush to be replaced. The two fixing parts are arranged in opposite directions on the replacement box, so that when the fixing part rotates to the replacement position, the brushes on the fixing part are all facing upwards, so as to facilitate connection and separation with the first motor.

[0046] In this embodiment, as Figures 1 to 5 As shown, the replacement box 5 rotates horizontally. There are two fixing parts on both sides of the rotation center of the replacement box 5, that is, there are two fixing parts on the replacement box 5. One of the two fixing parts can be used to hold and fix the brush 4 that is in use, and the other can be used to hold and fix the brush 4 to be replaced. The two fixing parts are arranged in the same direction on the replacement box 5. When the fixing part rotates to the replacement position, the brush 4 on the fixing part is facing upward, so as to facilitate connection or separation with the first motor 3.

[0047] Furthermore, such as Figure 3 and Figure 4 As shown, the fixing part includes a guide channel 8 and a fixing hole 9 formed on the replacement box 5. When both the fixing part and the first motor 3 move to the replacement position, the connecting part 13 of the brush 4 on the first motor 3 is located in the fixing hole 9.

[0048] The guide channel 8 connects the edge of the replacement box 5 and the fixing hole 9. When the brush 4 is inserted into the fixing part, the connecting part 13 on the brush 4 can pass horizontally through the guide channel 8 into the fixing hole 9. When the brush 4 is removed from the fixing part, the connecting part 13 on the brush 4 can move horizontally and exit from the fixing hole 9 through the guide channel 8. The fixing hole 9 is used to fix and support the connecting part 13, allowing the brush 4 to be placed inside the replacement box 5. A non-circular limiting groove 10 is formed on the upper side of the replacement box 5, and the fixing hole 9 is located at the bottom of the limiting groove 10. Figure 6 As shown, the outer circumference of the connecting part 13 is provided with a limiting protrusion 11 that matches the limiting groove 10. Through the cooperation of the limiting groove 10 and the limiting protrusion 11, when the connecting part 13 is located in the fixing hole 9, the brush 4 cannot rotate relative to the replacement box 5, thereby facilitating the threaded structure cooperation between the first motor 3 and the brush 4, which makes it easy for the first motor 3 to connect and separate from the brush 4. The horizontal cross-sectional shape of the limiting groove and the limiting protrusion can be rectangular or square.

[0049] In addition, such as Figure 4 and Figure 5 As shown, an inverted trumpet-shaped guide portion 12 is formed on the lower side of the replacement box 5, and the guide portion 12 is coaxially arranged with the fixing hole 9. In this way, when the first motor 3 is connected to the brush 4 in the replacement box 5, the rotary joint 7 on the first motor 3 can be aligned with the connecting portion 13 in the fixing hole 9 through the guiding action of the guide portion 12, so as to realize the quick connection between the first motor 3 and the brush 4.

[0050] Furthermore, the axial section of the fixing hole 9 is an inverted isosceles trapezoid, and the shape of the connecting part 13 is adapted to the shape of the fixing hole 9. When the connecting part 13 is placed in the fixing hole 9, due to gravity, the connecting part 13 and the fixing hole 9 will be coaxial, so that the rotary joint 7 on the first motor 3 can be aligned with the connecting part 13 in the fixing hole 9.

[0051] In this embodiment, as Figure 7 and Figure 8 As shown, the drive assembly includes a base plate 14, a third motor 15, a support frame 16, a first sector gear 17, a second sector gear 18, and a fourth motor 19. The first and second motors are both servo motors, enabling precise control of rotation, thereby controlling the accuracy of the first motor's movement and ensuring precise brush replacement.

[0052] Specifically, the first sector gear 17 is rotatably connected to the upper surface of the substrate 14, the third motor 15 is fixed on the substrate 14, the output shaft of the third motor 15 is provided with a first gear 20, the first gear 20 meshes with the first sector gear 17, the support frame 16 is fixed on the rotating shaft of the first sector gear 17 and rotates with the rotating shaft of the first sector gear 17, that is, when the first sector gear 17 rotates, the support frame 16 can rotate with it, the second sector gear 18 is rotatably connected to the support frame 16, the fourth motor 19 is fixed on the support frame 16, the output shaft of the fourth motor 19 is provided with a second gear 21, the second gear 21 meshes with the second sector gear 18.

[0053] The robotic arm 2 includes a first arm 2-1 and a second arm 2-2 arranged in parallel. The first arm 2-1 is located above the second arm 2-2. The first end of the first arm 2-1 is hinged to the first motor 3. The second end of the first arm 2-1 is fixed on the rotating shaft of the second sector gear 18 and rotates with the rotating shaft of the second sector gear 18. That is, when the second sector gear 18 rotates, the first arm 2-1 can rotate with it. The first end of the second arm 2-2 is hinged to the first motor 3, and the second end of the second arm 2-2 is hinged to the support frame 16.

[0054] Thus, when the third motor 15 is working, it drives the support frame 16 to rotate horizontally via the first gear 20 and the first sector gear 17. The support frame 16 then drives the first motor 3 to swing left and right via the first arm 2-1 and the second arm 2-2. When the fourth motor 19 is working, it drives the first arm 2-1 to rotate vertically via the second gear 21 and the second sector gear 18, thereby driving the first motor 3 on the first end of the first arm 2-1 to move up and down. This drive assembly can drive the first motor to move up and down and swing left and right, and its structure is simple and compact.

[0055] The above description is merely a specific embodiment of this utility model. Under the teachings of this utility model, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of this utility model, and the scope of protection of this utility model should be determined by the scope of the claims.
