[0040] like Figure 2 As shown, there is a partition between the toothpaste containing cavity and the toothbrush holder cavity of the box body 1, and an axial hole is opened on the partition. A bearing that rotates with the end of the screw 12 is installed in the axial hole of the partition. A sleeve hole is opened at the rear end of the box body 1. A sleeve 121 is fixedly installed in the sleeve hole of the box body 1, and the end of the screw 12 is rotatably installed in the sleeve 121.

[0041] In order to realize the control of each motor, the box 1 of the present invention is provided with a control box 18, and the control box 18 is provided with a motor control button A, a motor control button B and a motor control button C. The motor control button A is electrically connected to the motor A10, the motor control button B is electrically connected to the motor B, and the motor control button C is electrically connected to the motor C16. The present invention can set four buttons on the control box 18, and the four buttons are respectively a fast-forward button for installing new toothpaste, a fast-rewind button for removing the used toothpaste, a power button, and a parameter setting button. When setting the parameters, the fast-forward and fast-rewind buttons have selection and determination functions. The control of the motor can be uniformly controlled by a single-chip microcomputer (MCU), and the entire toothpaste squeezing process is a linked motion process; when the toothpaste squeezing machine detects the toothbrush, the toothpaste squeezing device performs squeezing motion according to the distance set by the parameters, squeezes the toothpaste from the toothpaste tube and falls on the toothbrush, and at the same time, the toothbrush sliding support plate 52 pushes the toothbrush outward, and when the extruded amount of toothpaste reaches the amount set by the parameters, the toothpaste squeezing device no longer moves, and the toothbrush sliding support plate 52 returns to the original position.

[0042] In order to realize automatic control of each motor, the present invention also includes an automatic toothpaste squeezing control system. A toothbrush groove is provided on the toothbrush sliding tray 52. ​​A photoelectric sensor 56 corresponding to the toothbrush groove of the toothbrush sliding tray 52 is provided on the limiting slide groove of the top plate 51.

The motor control module A is electrically connected to the motor A10, the motor control module B is electrically connected to the motor B, and the motor control module C is electrically connected to the motor C16. When the user puts the toothbrush on the toothbrush sliding tray 52, the photoelectric sensor 56 detects the toothbrush insertion signal, and after being processed by the automatic toothpaste squeezing control system (specifically the single-chip microcomputer in the control box), the driving motor B (not shown in the figure) drives the cam 13 to rotate counterclockwise by a certain angle (such as Figure 6 As shown in the figure, the rocker 14 is pushed to overcome the effect of the spring 15 to drive the sealing arm to rotate, thereby driving the sealing cover plate of the toothpaste tube 4 to rotate a certain angle to open the tube mouth of the toothpaste tube 4. The automatic toothpaste squeezing control system controls the motor C16 to rotate, drives the gear shaft 55 to rotate through the gear C161, the idler wheel 163, and the gear D162, and then drives the toothbrush sliding support plate 52 to move outward through the gear E551 on the gear shaft 55 and the rack under the toothbrush sliding support plate 52. At the same time, the toothpaste squeezing device squeezes the toothpaste tube 17 outward, and the toothpaste flows out of the toothpaste tube 17 and flows onto the toothbrush. When the toothbrush sliding support plate 52 moves outward a certain distance, the toothpaste squeezing operation is completed, and the user can take the toothbrush out of the toothpaste squeezing machine. Then, under the control of the automatic toothpaste squeezing control system, the toothbrush sliding support plate 52 returns to its original position, the motor B reverses and returns to its original position, the rocker 14 returns to its original position under the spring force of the spring 15, and the sealing cover plate re-closes the tube opening of the toothpaste conduit 4. When squeezing toothpaste, the automatic toothpaste squeezing control system controls the motor A10 to rotate and drive the gear A11 to rotate, and the screw 12 (the screw 12 can be a lead screw) is driven to rotate through the meshing of the gear A11 and the gear B122, and the screw 12 is screwed with the threaded hole of the squeezing bracket 9 to drive the squeezing bracket 9 to rotate as shown in the figure. Figure 4 The toothpaste tube 17 is squeezed by the squeezing rod 91 (two squeezing rods 91 can be provided at the upper and lower positions on the top of the squeezing bracket 9), so that the toothpaste in the toothpaste tube 17 is squeezed out from the toothpaste outlet at the left end. The extended part of the squeezing bracket 9 (i.e., the slider 92) is installed in the guide groove 921 on the side of the box body 1 to slide, and the guide groove 921 plays an axial guiding role. The above operation is based on the operation process of the toothpaste squeezer placed horizontally (such as Figures 1 to 8 When you want to put the toothpaste vertically on the wall, you need to rotate the toothpaste squeezer 90 degrees (as shown in the figure). Fig. 9 As shown), the toothpaste squeezer can be installed on a vertical wall for use.
