[0069] The working principle of the portable electric toothbrush for the disabled based on Example 1 is:

[0070] First, in order to facilitate the use of the toothbrush by the disabled, the user can pick it up by the toothbrush handle 2 (some disabled people who have lost their arms can use their toes to hold it upright), then put the electric toothbrush 1 into the user's mouth, then bite the teeth lightly on the inside of the electric toothbrush 1, so that the teeth are in contact with the upper end surface of the column 24 and the column 24 is pressed down at the same time, and the semi-card ball 27 slides inside the inner arc groove 29, and the inner arc groove 29 drives the cylinder 23 to rotate relatively, and then the first tooth plate 17 and the second tooth plate 31 are driven to move relatively through the first tooth groove 25 and the second tooth groove 26;

[0071] Second, when the first tooth plate 17 moves to squeeze the first spring 16, it drives the right-angle plate 18 to move, and synchronously drives the bristles 47 to move closer to the user's teeth. When facing different groups of people, it can also be used by self-adjustment according to the degree of occlusion.

[0072] Third, synchronously, when the cylinder 23 rotates, the block 28 is also synchronously driven to move inside the arc groove 21. The block 28 moves through the toggle switch 22 to synchronously turn on the toggle switch 22, and the command is transmitted to the wireless communication module. Then, the signal is transmitted to the controller through wireless remote control. The controller converts the signal into a control signal to control the electromagnets 41 on the first long plate 39 and the second long plate 40 to intermittently open and close, so that the electromagnets 41 are intermittently pushed up and down by the same level of repulsion, and the connecting column 43 is driven by the trapezoidal plate 42 to drive the square plate 46 to move up and down, and synchronously through the hole 37 as a fulcrum, the bristles 47 are repeatedly tilted to achieve brushing and cleaning of the teeth. On the contrary, when the use is completed, the teeth are loosened and the first spring 16 is rebounded to drive the cylinder 23 to rotate in the opposite direction, and the toggle switch 22 can also be closed by the reverse movement of the block 28.
