The first sensor 3 is a pressure sensor. When the toothbrush head 52 receives the brushing pressure, the toothbrush head 52 drives the driving shaft 51 to slightly incline, and the driving shaft 51 and the main board 2 are connected by the connecting piece 4, when the driving shaft 51 slightly inclines, the driving shaft 51 drives the connecting piece 4 to slightly deform, the first sensor 3 senses the deformation force of the part, and the first pressure data formed by the deformation force of the part is transmitted to the main board 2 through the connecting piece 4.

In the present embodiment, the drive shaft 51 is provided with a mounting groove 511, and the first sensor 3 is mounted in the mounting groove 511 via the connection member 4. Specifically, one end of the connecting piece 4 is installed in the installation groove 511, and the first sensor 3 is installed on one end of the connecting piece 4, so that one end of the connecting piece 4 can be connected with the groove wall of the installation groove 511 in a flat manner, and the first sensor 3 can be connected with one end of the connecting piece 4 in a flat manner.

Further, the mounting groove 511 is provided near the axis of the drive shaft 51. In this way, one end of the connecting member 4 is mounted in the mounting groove 511 near the axis of the driving shaft 51, so that the connecting member 4 can be micro-deformed following the micro-tilting of the driving shaft 51, to improve the accuracy of sensing by the first sensor 3.

Further, the electric toothbrush further comprises a first adhesive member (not shown in the drawings), by which the first sensor 3 is connected to the connecting member 4. Specifically, the first adhesive member is a liquid self-adhesive, so that the first sensor 3 can be fixed on the connecting member 4.

Specifically, the second sensor 8 is an ultrasonic pressure sensor. Because the circuit board 7 is located in the accommodating space 11 of the shell 1, and the circuit board 7 is glued to the pressing part 12, the pressing part 12 is pressed, the pressing part 12 deforms and transmits pressure to the circuit board 7, so that the circuit board 7 generates micro deformation, the second sensor 8 senses the deformation force of the part to form second pressure data, meanwhile, after the circuit board 7 generates micro deformation, the circuit board 7 can drive the conductive elastic sheet 9 to generate elastic deformation, so that the conductive elastic sheet 9 can always contact with the circuit board 7, and the second sensor 8 can transmit the second pressure data to the main board 2 through the circuit board 7 and the conductive elastic sheet 9, so that the main board 2 can open and close the electric toothbrush according to the second pressure data, and accordingly the opening and closing of the toothbrush head 52 are controlled.

It should be added that the main board 2 can turn on and off the electric toothbrush according to the second pressure data, after the electric toothbrush is turned on, the main board 2 controls the toothbrush head 52 to move or stop according to the first pressure data, and after the brushing is finished, the main board 2 turns off the electric toothbrush according to the second pressure data.
