Problems solved by technology

[0003] The pressure detection structure of the above structure is not sensitive to the small pressure detection on the brush head due to its close distance from the brush head, resulting in inaccurate pressure detected by the overall pressure detection structure, which is only suitable for the user when brushing teeth excessively As a reminder, it is impossible to expand the functions of the electric toothbrush in combination with pressure detection, and slotting on the output shaft will also increase the possibility of defects in the output shaft to a certain extent, and the output shaft is out of The state of high-frequency oscillation increases the risk of the output shaft breaking

Embodiment 1

[0042] Embodiment 1, comprises the following steps:

[0043] When the sensor detects that the pressure is between the initial value and the first threshold, the control motor assembly does not start;

[0044] When the sensor detects that the pressure is between the first threshold and the second threshold, the motor assembly is controlled to start with a fixed output power;

[0045] When the sensor detects that the pressure is greater than the second threshold, it sends out a warning signal of excessive pressure.

[0046] When the sensor detects that the pressure of the brush head is 0-50g, the motor in the control motor assembly does not start, which may be due to toothpaste being applied, so when the pressure is too low, it is not necessary to start the motor to vibrate the brush head.

[0047] For example, when the sensor detects that the pressure of the brush head is 50-200g, the motor in the motor assembly is controlled to run at the optimal output power. At this time, t...

Embodiment 2

[0049] Embodiment 2, comprises the following steps:

[0050] When the sensor detects that the pressure is between the initial value and the third threshold, the control motor assembly does not start;

[0051] When the sensor detects that the pressure is between the third threshold and the fourth threshold, the motor assembly is controlled to start, and the output power of the motor is proportional to the pressure of the brush head;

[0052] When the sensor detects that the pressure is between the fourth threshold and the fifth threshold, the motor assembly is controlled to start, and the output power of the motor is inversely proportional to the pressure of the brush head;

[0053] When the sensor detects that the pressure is between the fifth threshold and the sixth threshold, it sends out a warning signal of excessive pressure;

[0054] When the sensor detects that the pressure is greater than the sixth threshold, the motor assembly is controlled to stand by.

[0055] When...

Abstract

The invention relates to an electric toothbrush and a tooth brushing starting method thereof. The electric toothbrush comprises a shell, a motor assembly, a brush head and a sensing member, wherein the motor assembly is mounted in the shell; the sensing member comprises a fixing segment, a deformation segment and a connecting segment, the fixing segment is fixed relative to the shell, the connecting segment is fixed to one end of the motor assembly, an output rod is arranged at the other end of the motor assembly, and the brush head is mounted on the output rod; and the brush head and the motor assembly are connected to form a force arm, force for pressing the brush head is transmitted to the deformation segment so that the deformation segment is deformed, a sensor is mounted in the deformation segment and is used for feeling deformation of the deformation segment, and the sensor and the motor assembly are in electric control connection. According to the electric toothbrush and the tooth brushing starting method thereof disclosed by the application, pressure borne by the brush head can be precisely detected, and a detected pressure value is used for controlling starting and stopping of a motor.

Description

technical field [0001] The invention relates to the field of electric toothbrush control structures, in particular to an electric toothbrush and a toothbrushing starting method thereof. Background technique [0002] The prior art discloses an electric toothbrush with a device for detecting the pressure of the brush head, including a motor and a brush head, the motor has an output shaft, the brush head is plugged and fixed on the output shaft, and the brush head is driven by the motor to start Brushing teeth, and a pressure detection structure is set on the output shaft, through which the user is reminded when brushing teeth too hard to prevent wear; the pressure detection structure includes a stress trigger and a stress detection on the surface of the output shaft, The stress trigger part is a groove arranged on the output shaft, and the groove increases the elastic deformation capacity of the output shaft, so that the stress detection part corresponding to the groove can de...
