[0109] The working principle of the intelligent shoe cleaning machine described in the present invention is as follows:

[0110] The bidirectional lead screw 11 in the intelligent shoe cleaning machine described in the present invention is connected and fixed to the box body 1 through the first ball bearing 9, the second ball bearing 13 and other connecting parts, and is driven by the first servo motor 2. The first connector 10 and the second connector 12 are mounted on the bidirectional lead screw 11 to form a lead screw nut pair. The first servo motor 2 drives the bidirectional lead screw 11 to rotate. The clockwise or counterclockwise rotation of the bidirectional lead screw 11 drives the first connector 10 and the second connector 12 to move in opposite directions. In order to prevent the shoes from shaking due to the force applied during the cleaning process, guide rails 3 symmetrically placed on the front and rear sides of the bidirectional lead screw 11 are installed in the box body 1. 0, the bottom end of the rectangular connecting plate is provided with a first connector 10 of a dovetail slider, the second connector 12 and the dovetail grooves on two guide rails 30 with the same structure are in contact and matched, and move along the longitudinal direction of the guide rail 30 to prevent the shoes from shaking back and forth; the bottom flanges of the first connector 10 and the second connector 12 are respectively connected to a second servo motor 17, and the bottom end of the second servo motor 17 is connected to the shoe holder 20. The shoes to be cleaned are mounted on the shoe holder 20, and the rotation of the second servo motor 17 drives the shoes to rotate. During the shoe brushing process, the second servo motor 17 rotates slowly, and during the spin drying process, the second servo motor 17 rotates quickly.

[0111] Nowadays, there are many kinds of shoes, and the directions of the patterns on the shoes are different. The angles formed between the angles of the patterns and the bottom surfaces of the shoes are different. According to common sense, in the actual shoe brushing process, brushing along the direction of the grain will achieve a better cleaning effect; the connecting rod mechanism controls the inclination angle of the brush 24 through the operation of the DC push rod 23. Under the condition that the relative angle between the shoe and the box body 1 remains unchanged, the relative angle between the shoe and the brush 24 is changed by changing the adjustment of the relative angle between the brush 24 and the box body 1. In this way, the cleaning direction of the bristles coincides with the grain direction of the shoe, achieving a better cleaning effect. The operation of the brush 24 is powered by a DC motor 27 fixedly connected to the second connecting rod 22.

[0112] The function of using the bidirectional lead screw 11 is as follows: when the first servo motor 2 is working, the first servo motor 2 itself has been fixed to the outer wall of the left box wall of the box body 1 by the third bolt 16. When the first servo motor 2 is working, the bidirectional lead screw 11 is driven to rotate. The dovetail sliders at the bottom of the first connector 10 and the second connector 12 are in contact with the dovetail grooves of the guide rail 30 installed on the box body 1, so the first connector 10 and the second connector 12 cannot shake. The first connector 10 and the second connector 12 form a lead screw nut pair with the bidirectional lead screw 11, and are symmetrically arranged at the left and right ends of the bidirectional lead screw 11. When the bidirectional lead screw 11 rotates, the first connector 10 and the second connector 12 move to the left and right ends respectively, driving the two identically structured shoe clamps 20 connected to the two identically structured second servo motors 17 in the two identically structured shoe clamping devices connected to the first connector 10 and the second connector 12 and the two shoes installed on the shoe clamps 20 to move to the left and right sides, ensuring that every position of the shoe can be brushed.

[0113] A connecting rod mechanism is formed by connecting a first connecting rod 21, a second connecting rod 22 and a DC electric push rod 23 in sequence; one end of the first connecting rod 21 is connected to the connecting rod support No. 1 on the box body 1 by a pin shaft, and one end of the second connecting rod 22 is connected to the other end of the first connecting rod 21 by a rotating pin 28. A side ear that can be assembled with the DC electric push rod 23 to form a rotating connection is provided on the rod body of the second connecting rod 22. The side ear is connected to the power output end of the DC electric push rod 23 by a pin shaft to form a rotating connection, and the rear end of the DC electric push rod 23 is connected to the power output end of the DC electric push rod 23 by a pin shaft. A pin shaft is used to form a rotational connection between the end and the No. 2 push rod support on the box body 1; when the DC push rod 23 is working, the angle of the second connecting rod 22 will change significantly, driving the DC motor 27 installed in various grooves on the front side of the upper end of the second connecting rod 22 and the brush 24 equipped with the DC motor 27 to change their angles. Under the condition that the angle of the shoe does not need to be adjusted, the shoe brushing machine can adapt to the texture of the shoe at any angle by changing the angle of the brush 24. Brushing along the texture of the shoe will make the shoe cleaner.

[0114] The brush 24 set according to different shoe materials can cooperate with the DC motor 27 installed in various grooves on the front side of the upper end of the second connecting rod 22. The brushes 24 with different hardness and different materials are used to better adapt to the materials of different shoes, so as to achieve the purpose of cleaning the shoes while fully protecting the shoes.

[0115] Shoe clamps 20 of different sizes are provided according to shoes of different sizes, and can be used in conjunction with the second servo motor 17 .

[0116] During the operation of the present intelligent shoe brushing machine, a single chip microcomputer is used to control the operation of the intelligent shoe brushing machine. Because the distance from the toe of the shoe to the center axis of the flange of the shoe holder 20 is different from the distance from the tail of the shoe to the center axis of the flange of the shoe holder 20, and the working radius that the brush 24 can clean is certain, the shoes need to be moved to both sides to ensure that the two shoes will not collide during the shoe brushing process. The control difficulty of the present intelligent shoe brushing machine lies in ensuring that the first servo motor 2 connected to the box body 1 and the two second servo motors 17 with the same structure in the two shoe holders with the same structure can ensure that the two shoes will not collide during operation and that the bristles can brush both shoes. During the entire operation of the intelligent shoe brushing machine, in order to balance the overall situation, the two second servo motors 17 with the same structure in the two shoe holders with the same structure have different rotation directions, namely, one rotates clockwise and the other rotates counterclockwise.

[0117] In order to avoid the situation where the brush cannot be brushed, different modes should be selected for different shoe sizes. For small shoe sizes, the two-way screw 11 rotates fewer times, and the first connector 10 and the second connector 12 move a shorter distance to the left and right. For large shoe sizes, the two-way screw 11 rotates more times, and the first connector 10 and the second connector 12 move a longer distance to the left and right.

[0118] The working process of this intelligent shoe brushing machine is:

[0119] The user clamps the shoes to be washed on the shoe clamping device 20, closes the box door and turns on the start switch, the spray device 38 sprays a mixture of cleaning agent and clean water, and at the same time, the second servo motor 17 in the shoe clamping device works to drive the shoes to rotate slowly, and the first servo motor 2 fixedly connected to the box body 1 works to drive the shoes to move to both sides to ensure that the cleaning agent is sprayed evenly. After the spray device 38 stops working, the DC motor 27 connected to the brush 24 works to drive the brush 24 to rotate. At the same time, the second servo motor 17 in the shoe clamping device continues to operate slowly, and the first servo motor 2 fixedly connected to the box body 1 works to drive the shoes to move to both sides to ensure that every position of the shoe is brushed. After the shoe rotates one circle, the DC push rod 23 works to adjust the working angle of the brush 24. Subsequently, the above process is repeated, that is, the shoe rotates one circle, the brush 24 changes a working angle until the brush 24 is in the limit position, and then returns to work, the shoe brushing is completed, the DC motor 27 stops working, and the brush 24 stops rotating. Then, the spray device 38 sprays clean water to clean the soap foam on the shoes. Then, the second servo motor 17 in the shoe clamping device rotates at high speed to dry the water on the shoes. At the same time, the drying device 39 and the ultraviolet light disinfection device 40 are turned on to dry and sterilize the shoes. Finally, the deodorizing device 41 is turned on to remove the peculiar smell of the shoes.
