Method for starting electric toothbrush without key

Abstract

The invention discloses a key-free starting method for an electric toothbrush, which comprises a toothbrush body, a control chip arranged on a circuit board in the toothbrush body, a transmitting coil which is arranged on the circuit board and is controlled by the control chip to generate a magnetic field, and a receiving coil which is arranged on a motor in the toothbrush body and is used for generating current by inducing the magnetic field, current A1 generated by the receiving coil when the circuit board and the motor are in an initial distance is recorded through the control chip, and when a brush head on the toothbrush body is in contact and stressed, the motor is driven to approach or leave the circuit board, so that the distance between the receiving coil and the transmitting coil is changed, and the current generated by induction of the receiving coil is changed; at the moment, the current generated by induction of the receiving coil is A2, and the control chip judges whether the brush head is in contact with the teeth or not according to whether the current A2 is equal to the current A1 or not, so that the motor is controlled to start and stop. On-off operation of the electric toothbrush is achieved through necessary actions during tooth brushing, and the electric toothbrush is opened when entering a mouth and stopped when leaving the mouth.

Description

Technical field: [0001] The invention relates to the field of electric toothbrushes, in particular to a method for starting an electric toothbrush without keys. Background technique: [0002] The electric toothbrush is a kind of toothbrush. The high-frequency vibration of the brush head is generated by the rapid rotation or vibration of the electric core, and the toothpaste is instantly decomposed into fine foam, which deeply cleans the teeth. At the same time, the vibration of the bristles can promote the oral cavity. Blood circulation, massage effect on gum tissue. [0003] With the improvement of people's living standards, more and more electric toothbrushes are applied to people's daily life, and because electric toothbrushes are easy to use and have an excellent cleaning effect, they are loved by consumers. [0004] At present, the electric toothbrushes on the market generally use button control, and the button control method requires a control button to be installed o...

AI Technical Summary

Problems solved by technology

[0004] At present, electric toothbrushes on the market are generally controlled by buttons, and if the button control method is adopted, control buttons need to be installed on the casing, thus not only causing a decline in waterproof performance, but also prone to fatigue when the buttons are used for a long time, reducing the wear and tear of the toothbrush. service life
