Under the action of the pushing plate 232, the sanitary ware accessories inside the box body 102 are pushed to the surface of the discharge port 106, so that the sanitary ware accessories are exported from the inside of the box body 102 through the discharge port 106 for automatic feeding. When the pushing plate 232 moves, the pushing plate 232 drives the rotating balls 233 to rotate. Under the action of the rotating balls 233, the friction force when the pushing plate 232 moves is greatly reduced, making it more labor-saving when the pushing plate 232 moves, so as to realize the function of automatic feeding of the feeding device.

[0031] Working principle: When in use, first place the feeding box 1 on the surface of the feeding pipe 103, so that the feeding box 1 drives the second magnet 33 to move into contact with the surface of the first magnet 32. Under the elastic force of the extension spring 35 in the groove, the arc-shaped clamping part 34 is driven to move, so that the arc-shaped clamping part 34 clamps onto the surface of the feeding box 1. Under the combined action of the arc-shaped clamping part 34 and the extension spring 35, the feeding box 1 is positioned and assembled. Under the magnetic attraction of the second magnet 33 and the first magnet 32, the feeding box 1 is installed on the surface of the feeding pipe 103, thus completing the assembly between the feeding box 1 and the feeding pipe 103, realizing the function of convenient assembly of the feeding device, so that the feeding device can be conveniently assembled by the user during use, and making the feeding device more convenient for the user to operate.

[0032] Subsequently, the user places the sanitary ware accessories inside the feeding box 1. The sanitary ware accessories enter the inside of the feeding pipe 103 and the fixed pipe 104, and then enter the inside of the discharging pipe 105 through the fixed pipe 104. Subsequently, the sanitary ware accessories enter the inside of the box body 102.

Under the action of the electric push rod 21, the moving plate 231 and the pushing plate 232 move inside the box body 102. Under the action of the pushing plate 232, the sanitary ware accessories inside the box body 102 are pushed to the surface of the discharging port 106, so that the sanitary ware accessories are discharged from the inside of the box body 102 through the discharging port 106 for automatic feeding. When the pushing plate 232 moves, the pushing plate 232 drives the rotating ball 233 to rotate. Under the action of the rotating ball 233, the friction force of the pushing plate 232 during movement is greatly reduced, making the pushing plate 232 more labor-saving during movement, realizing the function of automatic material pushing of the feeding device, so that the feeding device can automatically push the materials out of the inside of the box body 102 during use, enabling the feeding device to guide and feed the sanitary ware accessories during use, and making the feeding device have a higher degree of automation during use.

[0033] Subsequently, the user tightens the mounting stud 42 on the surface of the mounting block 41, installs the driven sprocket 433 on the surface of the blanking pipe 105, and then the user operates the control button 101 to make the control button 101 control the driving motor 431 to work. Under the action of the driving motor 431, the driving sprocket 432 is driven to rotate on the surface of the box body 102. Under the meshing action of the driving sprocket 432 and the driven sprocket 433, the driven sprocket 433 is driven to rotate. When the driven sprocket 433 rotates, the driven sprocket 433 drives the blanking pipe 105 and the box body 102 to rotate at the bottom of the material guiding pipe 103. When the box body 102 rotates, the box body 102 drives the position of the discharge port 106 to be adjusted, so as to adjust the feeding position of the sanitary ware accessories, so as to realize the function of multi-angle feeding of the feeding device, so that the feeding device can adjust the feeding angle of the sanitary ware accessories according to needs when in use, making the feeding device more meet the user's needs when in use, and finally completing the use work of the feeding device.
