Further the buffer assembly includes a probe, a resilient member disposed between the pressure sensor and the probe.

Furthermore, one end of the probe is abutted against the circuit board and is used as a current path between the pressure sensor and the circuit board.

Specifically, one end of the probe, which is abutted against the circuit board, is a hemispherical protrusion.

Further, the buffer assembly further comprises a connection post disposed between the probe and the pressure sensor.

Further, buffer component still includes the parcel the probe side with the spacing post of elastic component side.

Further, the buffer assembly comprises an elastic piece, and the elastic piece is arranged between the pressing part and the pressure sensor; one end of the pressure sensor is abutted against the circuit board and is electrically connected with the circuit board.

Specifically, the elastic member is a spring.

Specifically, the outer surface of the electric toothbrush is provided with a groove, and the pressing part is formed by the outer surface of the electric toothbrush surrounded by the groove.

Specifically, the pressure sensor and the buffer assembly are respectively provided with two or more than two.

The improvement of this patent brings the following advantage:

(1) the embodiment of the application provides a pressure button of an electric toothbrush, and a buffer assembly is arranged between a pressing part and a circuit board as a bottom supporting support. Buffering subassembly can be when the user presses the pressure and feels the button, and the buffering absorbs the pressure that increases suddenly, avoids not having the buffering and the pressing that appears too hard feels, lets press and feels more soft smooth, improves the use experience that presses the button.

(2) In the prior art, a pressure sensor and a circuit board are connected through an FPC (flexible printed circuit) to transmit signals, but the FPC and the pressure sensor are attached to the inner wall of a shell of an electric toothbrush, the shell of the electric toothbrush is generally deep, and a pressing part and the pressure sensor are also located at a deep position in the shell. This requires that the FPC is extended long using the FPC, and then the FPC is integrally mounted in the housing after the circuit board is attached. Because the interior design of electric toothbrush is very compact, the operation of the FPC of overlength is inconvenient and FPC is also well accomodate in the shell. The pressure button of the embodiment of the application skillfully solves the problem through the flexible arrangement of the buffer component and the pressure sensor. In the pressure button of this application embodiment, pressure sensor or through buffer assembly and circuit board electric connection, or pressure sensor direct contact circuit board establishes current path, does not need FPC as the current path between pressure sensor and the circuit board, has solved the FPC operation inconvenience of overlength among the prior art and has also not good accomodate the problem of entering the shell at one stroke.

(3) The buffer component is arranged between the pressing part and the circuit board, so that the circuit board serving as a support can be prevented from being damaged by pressing pressure suddenly. When the pressing part is pressed, the elastic part absorbs the pressing pressure which is increased suddenly to prevent the pressure from being overlarge. After the user gives up pressure, the elastic member gradually releases the absorbed pressure. Therefore, the pressure change is more gradual, and the backing or the circuit board serving as the support is not easy to be damaged.

(4) As a further improvement, the probe is used as a support for the pressure sensor, so that the pressure originally spread on the whole pressure sensor is concentrated at the position connected with the probe, and the pressure of the area is greatly enhanced. Then originally less, the unable sensitive pressure that senses of pressure sensor when spreading out, after concentrating into reinforcing together, pressure sensor can respond to fast to let the pressure feel the button more sensitive.
