As shown in fig. 1 to 4, the electric toothbrush of the embodiment of the present application includes a toothbrush head 10, a switch 11, a first pressure sensor 12, a second pressure sensor 13, a driving motor 14, a flexible circuit board 15, a motor output shaft 16 and a toothbrush handle 17, wherein the switch 11 is located on the toothbrush handle 17, the flexible circuit board 15 and the driving motor 14 are accommodated inside the toothbrush handle 17, and the toothbrush head 10 is connected to the driving motor 14 through the motor output shaft 16. The first pressure sensor 12 and the second pressure sensor 13 are disposed on the flexible circuit board 15, preferably, the sensing area of the first pressure sensor 12 and the sensing area of the second pressure sensor 13 are located on the same side of the flexible circuit board 15, and the distance between the first pressure sensor 12 and the second pressure sensor 13 is 25-35 mm. The first pressure sensor 12 corresponds to the position of the motor output shaft 16 and is used for detecting the stress of the motor output shaft 16, and the second pressure sensor 13 corresponds to the position of the on-off key 11 and is used for detecting the stress of the on-off key 11.
Since the second pressure sensor 13 and the first pressure sensor 12 are formed as a module, and the distance between the core positions of the two sensors is short, mutual signal interference is easily generated, the flexible circuit board 15 can maintain the relative balance of the forces, and when the second pressure sensor 13 receives the key pressure transmitted from the housing 20, the flexible circuit board 15 can reduce a part of the influence on the first pressure sensor 12.
The sensing area of the first pressure sensor 12 faces away from the motor output shaft 16 and is not in contact with the motor output shaft 16, a pull rod 18 and a pressing plate 19 are further arranged inside the toothbrush handle 17, the pressing plate 19 is arranged on one side, facing away from the motor output shaft 16, of the first pressure sensor 12, one end of the pull rod 18 is fixed to the motor output shaft 16, and the other end of the pull rod 18 is connected with the pressing plate 19.
In this way, the first pressure sensor 12 and the second pressure sensor 13 form an integrated module, since the first pressure sensor 12 and the second pressure sensor 13 are both on the same side, the second pressure sensor 13 can directly generate a signal by pressing on the upper end, when the toothbrush head 10 is pressed, the first pressure sensor 12 is not below the output shaft 16 of the motor, and the pull rod 18 pulls the press plate 19 to transmit downward pressure, so as to trigger the sensing area of the first pressure sensor 12 to generate a signal.

Thus, the sensing area of the first pressure sensor 12 and the sensing area of the second pressure sensor 13 are located on the same side of the flexible circuit board 15, so that the manufacturing process of the flexible circuit board 15 can be simpler.
The outside of the first pressure sensor 12 is covered with a first resilient layer 22. The first elastic layer 22 may be a rectangular silicone sleeve, and the first pressure sensor 12 is wrapped in the rectangular silicone sleeve to ensure that the upper and lower parts of the first pressure sensor 12 are elastically supported.

One end of the first pressure sensor 12 is connected with a toothbrush main control board 27 through a flat cable, and the toothbrush head 10 is inserted at the front end of the output shaft 16 of the motor. When the toothbrush head 10 is placed in the oral cavity, the toothbrush head is subjected to pressure and simultaneously drives the motor output shaft 16 to generate weak deformation, the pull rod 18 is driven at the moment, the press plate 19 is pulled by the pull rod 18, the press plate 19 applies pressure to the first pressure sensor 12, and the sensing area of the first pressure sensor 12 can sense the deformation to generate a level change signal at the moment. When the tooth brushing force is large, the tooth brushing force directly acts on the toothbrush head 10, the toothbrush head 10 drives the motor output shaft 16 to generate large deformation, and the first pressure sensor 12 receives the large deformation and generates a corresponding level change signal from the surface. The toothbrush main control board 27 will make corresponding work adjustment according to the corresponding level change signal. Illustratively, the toothbrush main control board 27 may change the vibration to a weak vibration output or a red light alert according to the corresponding level change signal.
In the present embodiment, the on-off key 11 is a deformable region in the housing 20, the housing 20 may be a metal shell, and the on-off key 11 is a thinner region in the metal shell to facilitate pressing deformation.

In this embodiment, the first pressure sensor that corresponds with the toothbrush head in the electric toothbrush and the second pressure sensor that corresponds with the on-off key are integrated into a circuit board module, connect the signal through flexible circuit board. Because first pressure sensor and first pressure sensor's sensitivity is higher, for avoiding first pressure sensor and first pressure sensor's signal mutual interference, through after electric toothbrush starts, acquire first pressure sensor and second pressure sensor's measuring value respectively, then judge whether effective according to second pressure sensor's measuring value, and then control the on & off key work or close that first pressure sensor corresponds according to the judged result, guarantee that first pressure sensor and second pressure sensor can exert their function respectively, mutual noninterference, promote electric toothbrush's use experience.
In an embodiment, the determining module 302 is further configured to:

The first preset threshold is used for judging whether the operation of pressing the on-off key meets the condition of generating an on-off control signal, and the second preset threshold is used for judging whether the stress of the motor output shaft meets the condition of starting the driving electrode. When the detection value of the second pressure sensor is larger than or equal to the first preset threshold value, but the detection value of the first pressure sensor is larger than or equal to the second preset threshold value, the brush head works, the detection value of the second pressure sensor is judged to be invalid at the moment, and the switch control signal generated by the switch key is shielded to avoid mistaken closing during tooth brushing.

Therefore, after the first pressure sensor and the second pressure sensor are integrally designed, the switch of the electric toothbrush can be more accurately controlled by combining the control logic of the controller 30, and the mutual influence of induction between the sensors is avoided.
In another embodiment, the determining module 302 may be further configured to:
when the detection value of the first pressure sensor is larger than or equal to a second preset threshold value, confirming that the detection value of the second pressure sensor is invalid;
and when the detection value of the first pressure sensor is smaller than a second preset threshold value, confirming that the detection value of the second pressure sensor is valid.
Therefore, as long as the brush head works, the switch control signal generated by the switch key is shielded, and the mistaken closing during tooth brushing is avoided.
