1. Introduction of wireless charging electric toothbrush:
Wireless charging electric toothbrush, as the name suggests, mainly includes two aspects of technology application - Wireless charging management and electric toothbrush control. Now, let''s make a brief introduction to these two aspects. Wireless charging technology is based on the principle of near-field electromagnetic induction. The transmitter converts the electric energy into electromagnetic wave and transmits it to the receiver. The coil of the receiver uses the changing magnetic field to generate the induced current, so as to realize the purpose of charging the battery of electrical equipment. Compared with traditional toothbrush, electric toothbrush has more scientific and effective cleaning and dental health care function.
According to the working principle, electric toothbrush can be roughly divided into two categories: low-end motor rotary electric toothbrush and high-end magnetic core structure acoustic electric toothbrush. Compared with the former, the latter has the advantages of controllable force, swing direction and high frequency.

3. Operation instructions:
The main circuit of wireless charging electric toothbrush includes a mode conversion button, five working mode indicator LEDs and a red and green dual color LED for power indicator.
3.1 when the power is in full voltage state (greater than or equal to 4.1V), the following conditions shall be met:
(1) Press the mode switch button, the green power indicator is always on, indicating that the power is sufficient. At the same time, the first toothbrush mode indicator is on, indicating that the toothbrush is in "clean" mode;
(2) Press the mode switch button again, and the second toothbrush mode indicator light is on, which indicates that the toothbrush is in the "whitening" mode, and the swing strength of the toothbrush head changes slightly from strong to weak, and then gradually increases;
(3) Press the mode switch button again, and the third toothbrush mode indicator lights up, which indicates that the toothbrush is in the "grinding" mode, and the swing force of the toothbrush head increases significantly, and the change of the force becomes faster;
(4) Repeat the above key operation, enter the "gingival health care" mode, the fourth toothbrush mode indicator lights up, compared with the previous mode, the toothbrush head swings with constant force without change;
(5) Press the key again to enter the last "sensitive" mode, the indicator light of the fifth toothbrush mode is on, and the toothbrush head swings with the minimum constant force;
(6) Press the button again and the toothbrush is in standby mode.
(7) If the above key operation is continued, steps (1) to (6) can be repeated.
3.2 when the power is not at full voltage (less than 4.1V, greater than or equal to 3.2V), the green power indicator "breathing" flashes, indicating that the toothbrush should be charged, but the above toothbrush operation modes can still work normally.
3.3 when the power is under voltage (less than 3.2V), the red power indicator "breathing" flashes. At this time, the toothbrush can not work normally. Please charge it immediately. Press the button again and the toothbrush will switch to the standby mode.
3.4 when the toothbrush is charged, the mode conversion button is invalid, and the green power indicator "breathing" flashes, indicating that the toothbrush is in the charging state; until the charging reaches the full voltage state, the green indicator is always on, indicating that the toothbrush is fully charged.
