[0023] When installing battery, press control switch 18, start driving motor 10, the driving shaft of driving motor 10 rotates and drives rotating shaft 9 to rotate and further drives gear 8 to rotate, since only half of the surface of gear 8 is provided with teeth, when gear 8 rotates, it will drive rack 7 to move downward by engaging, rack 7 drives brush 4 to move downward together, when rack 7 moves downward, return spring 11 contracts, when the teeth of gear 8 are no longer engaged with rack 7, rack 7 moves upward to the initial position under the action of the elasticity of return spring 11, and the process is repeated, gear 8 rotates by driving motor 10, gear 8 drives rack 7 to descend by engaging and further compresses return spring 11, when gear 8 is no longer engaged with rack 7, rack 7 moves upward under the action of return spring 11, and the process of brushing teeth is completed.

[0024] Please refer to Figure 1-5 As shown, the bottom of the handle 1 is connected to the battery cover 13, and pin holes 14 are provided around the bottom of the handle 1. Pin shafts 15 are correspondingly provided around the bottom of the battery cover 13, and the pin shafts 15 are inserted into the pin holes 14. Grooves 16 are provided on both sides of the battery cover 13. A control switch 18 is provided on one side of the bottom of the toothbrush body 2. The control switch 18 and the drive motor 10 are electrically connected to the battery.

[0025] In specific implementation, when using, the user first places the thumb and index finger in the grooves 16 opened on both sides of the battery cover 13 respectively, then forcibly pulls the pin shaft 15 out of the pin hole 14, and then installs the battery in the battery slot 17 fixed at the bottom of the handle 1, and then reinserts the pin shaft 15 into the pin hole 14, and then fixes the battery cover 13 to the bottom of the handle 1 to prevent the battery from falling due to unstable installation and making the toothbrush unusable.

[0026] Furthermore, the control switch 18 is electrically connected to the drive motor 10. When the control switch 18 of the electric toothbrush is pressed, the battery supplies power to the drive motor 10, thereby driving the drive motor 10 to rotate. During this process, pressing the control switch 18 generates a signal that is transmitted to the control unit of the drive motor 10. Upon receiving the signal, the control unit of the drive motor 10 activates the drive motor 10, causing it to begin rotating.

[0027] In addition, in order to make the electric toothbrush have the effect of preventing accidental touch, we can hinge a dust cover (not shown in the figure) on the toothbrush body 2 so that the dust cover can rotate up and down.

[0029] After the battery is installed, press the control switch 18 to start the drive motor 10. The drive shaft of the drive motor 10 rotates, driving the rotating shaft 9 to rotate and then driving the gear 8 to rotate. Since only half of the surface of the gear 8 is provided with teeth, when the gear 8 rotates, it will drive the rack 7 to move downward through meshing, and the rack 7 drives the brush 4 to move downward together. When the rack 7 moves downward, the reset spring 11 contracts. When the teeth of the gear 8 no longer mesh with the rack 7, the rack 7 moves upward to the initial position under the action of the reset spring 11, and so on. The drive motor 10 drives the gear 8 to rotate, and the gear 8 drives the rack 7 to descend through meshing and then compresses the reset spring 11. When the gear 8 no longer meshes with the rack 7, the rack 7 moves upward under the action of the reset spring 11, completing the brushing process.
