Electric toothbrush coil

Electric toothbrush coilAt present, with the increasing demand for toothbrushes, the wireless charging technology often adopts electromagnetic induction type for low-power wireless charging, and often uses resonance type for high-power wireless charging. Use the received energy to charge the battery and use it for its own operation at the same time. Since the energy is transmitted between the charger and the power-consuming device by a magnetic field, the charger and the power-consuming device can have no exposed conductive contacts. Charging technology has been widely used in daily life and has become a very important technology in modern life.

The wireless electric toothbrush coil includes a box body, a fixing plate, a support rod, a coil mechanism and a bracket mechanism. The coil mechanism includes a coil body, an inner ring, a resonant capacitor, a resistor and a separator, and the bracket mechanism includes a support frame, a threaded ring, a threaded sleeve, and an opening. The coil body is double-wrapped to enhance the electromagnetic field, and then the resonance is adjusted by the resonant capacitor to make the vibration frequency equal to maximize the increase of the electromagnetic field, and the battery is charged by magnetic resonance, which greatly improves the The electric energy converted by the electromagnetic field is maximized; through the bracket mechanism, the toothbrush is placed in the bracket mechanism, and the height of the threaded sleeve is adjusted to change the size of the threaded sleeve, so that toothbrushes of different sizes can be stabilized on the bracket mechanism, and the water outlet on the groove It can ensure that the water on the toothpaste is drained away, reducing the risk, and at the same time, the bracket mechanism also improves the practicability.
