DETAILED DESCRIPTION

[0038] To make the objectives, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0040] In one embodiment of the present invention, an automatic shoe washing machine is provided. Figures 1 to 8As shown, the automatic shoe washing machine includes a washing chamber 1, a washing component, a driving component and a storage component.

[0041] Specifically, the brushing assembly is located in 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, and the output shaft of the first motor 3 and the connecting part 13 formed by the lower end of the brush 4 are detachably connected. The first motor 3 can drive the brush 4 to rotate, thereby cleaning the shoes, and the first motor 3 and the brush 4 can be flexibly disassembled and assembled to facilitate replacement of the brush 4. The driving 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 to clean various parts of the shoes.

[0042] In addition, 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 cavity 1. The replacement box 5 is arranged at the opening 6. The second motor is used to drive the replacement box 5 to rotate in the opening 6. At least two fixed parts are provided in the circumferential direction of the rotation center of the replacement box 5. The fixed parts are used to accommodate fixed brushes 4, that is, each fixed part can accommodate and fix a brush 4, so that when the first motor 3 and one of the fixed parts are moved to the replacement position, the brush 4 on the first motor 3 is inserted into the fixed part, and the second motor can drive different fixed parts to rotate and move to the replacement position.

[0043] The steps for replacing the brush of the automatic shoe washing machine in this embodiment are as follows:

[0044] First, if Figure 1 As shown, the second motor drives the replacement box 5 to rotate, so that the empty fixed part moves to the replacement position; secondly, the driving component drives the first motor 3 to move to the replacement position, at this time the brush 4 in use on the first motor 3 is inserted into the empty fixed part, and the first motor 3 is separated from the brush 4 in use; thirdly, the driving component drives the first motor 3 to leave the replacement position, so that the brush 4 in use is placed on the fixed part, as shown in FIG. Figure 2 As shown, the second motor drives the replacement box 5 to rotate again, so that the fixed part with the brush 4 to be replaced is moved to the replacement position; then, the driving component 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 driving component drives the first motor 3 to leave the replacement position, and the replacement of the brush 4 is completed.

[0045] This automatic shoe washing machine can replace its brushes to cope with different shoe-brushing processes. From the moment a pair of shoes are placed in the shoe washing machine until a pair of dry shoes are taken out of the machine, no other manual operations are required, completely freeing people's hands and making it more convenient and easy to use. For example, when dry-cleaning shoes, you can first brush the shoes with a harder brush, then replace the brush and use a softer brush to wipe off the foam on the shoes. Of course, this automatic shoe washing machine can also be used for shoe maintenance. For example, when maintaining leather shoes, you can first use a harder brush to brush off the dust on the shoes, then replace the brush and use a softer brush to pick up shoe polish and apply it to the surface of the leather shoes. Finally, the brush rotates at high speed to complete the polishing of the leather shoes.

[0046] In summary, in the automatic shoe washing machine of this embodiment, a first motor that can move up and down and swing left and right is provided, and the output shaft of the first motor is detachably connected to the brush, and a replacement box that can accommodate a fixed brush and can rotate is provided, so that the first motor can place the brush being used in the replacement box and obtain the brush to be used in the replacement box, thereby realizing automatic replacement of the brush, making it more convenient to use and providing a better user experience.

[0047] In this embodiment, if Figure 7 and Figure 8 As shown, the scrubbing assembly further comprises a rotary joint 7 .

[0048] The rotary joint 7 is fixed to the output shaft of the first motor 3. The upper end of the rotary joint 7 is formed with an external thread, and the lower end of the connecting portion 13 is formed with an internal thread that matches 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, thereby connecting 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, thereby separating the first motor 3 and the brush 4. This makes connecting and disconnecting the first motor 3 and the brush 4 more convenient.

[0049] It should be noted that when the first motor 3 is connected to the brush 4, the first motor 3 rotates forward and moves upward; when the first motor 3 is separated from the brush 4, the first motor 3 rotates reverse and moves downward, ensuring that the brush 4 remains stationary in the fixed part, making it easier to connect and separate the first motor 3 and the brush 4.

[0050] Of course, the output shaft of the first motor can also be detachably connected to the connecting portion on the brush through a screw-on structure, or the motor and the brush can be detachably connected through a strong magnetic structure, all of which are within the scope of protection of the present invention.

[0051] In other embodiments, the replacement box rotates in a vertical direction, that is, the rotating shaft of the replacement box is set in a horizontal direction, and fixed parts are respectively provided on both sides of the rotation center of the replacement box, that is, two fixed parts are provided on the replacement box, one of the two fixed parts can be used to accommodate and fix the brush being used, and the other can be used to accommodate and fix the brush to be replaced. The two fixed parts are set in opposite directions on the replacement box, so that when the fixed part is rotated to the replacement position, the brushes on the fixed part are all facing upward to facilitate connection and separation with the first motor.

[0052] In this embodiment, if Figures 1 to 5 As shown, the replacement box 5 rotates in the horizontal direction, and fixed parts are respectively provided on both sides of the rotation center of the replacement box 5, that is, two fixed parts are provided on the replacement box 5, one of the two fixed parts can be used to accommodate and fix the brush 4 being used, and the other can be used to accommodate and fix the brush 4 to be replaced. The two fixed parts are set in the same direction on the replacement box 5, so that when the fixed part is rotated to the replacement position, the brushes 4 on the fixed part are all facing upward, so as to facilitate connection or separation with the first motor 3.

[0053] Furthermore, if Figure 3 and Figure 4 As shown, the fixing portion includes a guide channel 8 and a fixing hole 9 formed on the replacement box 5. When the fixing portion and the first motor 3 are moved to the replacement position, the connecting portion 13 of the brush 4 on the first motor 3 is exactly located in the fixing hole 9.

[0054] The guide channel 8 is used to connect the edge of the replacement box 5 and the fixing hole 9. When the brush 4 is inserted into the fixing portion, the connecting portion 13 on the brush 4 can pass through the guide channel 8 in the horizontal direction and enter the fixing hole 9. When the brush 4 is removed from the fixing portion, the connecting portion 13 on the brush 4 can move in the horizontal direction and leave the fixing hole 9 through the guide channel 8. The fixing hole 9 is used to fix and support the connecting portion 13 so that the brush 4 can be placed in the replacement box 5. A non-circular limiting groove 10 is formed on the upper side of the replacement box 5. The fixing hole 9 is set at the bottom of the limiting groove 10, as shown in FIG. Figure 6 As shown, a limiting protrusion 11 is provided on the outer circumference of the connecting portion 13, which is adapted to the limiting groove 10. The limiting groove 10 and the limiting protrusion 11 cooperate to prevent the brush 4 from rotating relative to the replacement box 5 when the connecting portion 13 is located in the fixing hole 9, thereby facilitating the threaded structure between the first motor 3 and the brush 4, that is, facilitating the connection and separation of the first motor 3 and the brush 4. The horizontal cross-section of the limiting groove and the limiting protrusion can be rectangular or square.

[0055] In addition, if Figure 4 and Figure 5As shown, an inverted trumpet-shaped guide portion 12 is formed on the lower side of the replacement box 5. 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 guided by the guide portion 12 to align with the connecting portion 13 in the fixing hole 9, thereby achieving a quick connection between the first motor 3 and the brush 4.

[0056] In addition, the axial cross-section of the fixing hole 9 is an inverted isosceles trapezoid, and the shape of the connecting portion 13 is adapted to the shape of the fixing hole 9, so that when the connecting portion 13 is placed in the fixing hole 9, due to the action of gravity, the connecting portion 13 and the fixing hole 9 will be coaxial, so as to facilitate the alignment of the rotary joint 7 on the first motor 3 with the connecting portion 13 in the fixing hole 9.

[0057] In this embodiment, if 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. Both the first and second motors are servo motors, which can achieve precise control of rotation, thereby controlling the accuracy of the first motor's movement and ensuring accurate brush replacement.

[0058] Specifically, the first sector gear 17 is rotatably connected to the upper end surface of the base plate 14, the third motor 15 is fixed on the base plate 14, and the output shaft of the third motor 15 is provided with a first gear 20, which is engaged 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, and the output shaft of the fourth motor 19 is provided with a second gear 21, which is engaged with the second sector gear 18.

[0059] 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 to 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.

[0060] Thus, when the third motor 15 is operating, 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 support arm 2-1 and the second support arm 2-2. When the fourth motor 19 is operating, it drives the first support 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 support 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 has a simple and compact structure.

[0061] Another embodiment of the present invention provides a method for using the automatic shoe washing machine in the above embodiment, such as Figure 9 As shown, the method of use includes:

[0062] Step 01: The second motor drives the replacement box to rotate, so that the empty fixing part moves to the replacement position.

[0063] Step 02: The driving assembly drives the first motor to move to the replacement position, so that the brush in use on the first motor is inserted into the vacant fixing part, and the first motor is separated from the brush in use.

[0064] Step 03: The driving assembly drives the first motor to move away from the replacement position, and the second motor drives the replacement box to rotate, so that the fixed part with the brush to be replaced is moved to the replacement position.

[0065] Step 04: The driving assembly drives the first motor to move to the replacement position, and the first motor is connected to the brush to be replaced.

[0066] Step 05: The driving assembly drives the first motor to move away from the replacement position.

[0067] The use method can realize automatic replacement of the brush, making the automatic shoe washing machine more convenient to use.
