Description

technical field

[0001] The invention relates to a hand-held appliance for medical drilling and grinding teeth. Background technique

[0002] The intraoral lighting device of the high-speed turbo dental drill mobile phone generally adopts the optical fiber light source transmission technology, that is, a lighting bulb or a light-emitting diode is installed at the tail of the mobile phone handle or in the quick-fit joint. The light is guided into the front of the handpiece through the optical fiber for the illumination of the oral cavity during treatment.

[0003] This kind of device requires the treatment machine to provide power to ignite the small bulb, and a set of circuit transmission devices connected to the power supply, such as gold-plated double-ring contacts, six-hole connectors, etc. The power supply is generally obtained by converting an AC high-voltage power supply (such as 220V AC 50 Hz). Therefore, reliable safety facilities are required to ensure that users a...
