Furthermore, the bottom of the front end of the inner bottom shell is provided with heat dissipation holes.

Furthermore, the rear end face of the rear cover is provided with a paster.

The utility model discloses a theory of operation and efficiency: the key is touched once, the main control PCB outputs a row of low-temperature heating driving waveform driving transistors with adjustable duty ratio to heat the heating wire in a low-temperature state (55 +/-10 ℃); and lightly touching the key once again, outputting a row of high-temperature heating driving waveform driving transistors with adjustable duty ratio by the main control PCB board to heat the heating wire at a high temperature (65 +/-10 ℃). When the NTC negative temperature sensing sensor senses that the temperature exceeds 75 ℃, the heating is stopped.

Compared with the prior art, the utility model the advantage be:

1. stainless steel eyelashes book sticks up ware is because the use is loaded down with trivial details, and the time is longer, causes certain injury and book stick up the maintenance time shorter to facial skin very easily, the utility model discloses the product replaces stainless steel eyelashes with higher standard performance and rolls up the ware.

2. The utility model discloses an electronic eyelash curls up ware can shorten operating time, protects facial skin, and rolls up and maintain lastingly to the ware is wrapped up to higher standard performance replaces stainless steel eyelash.

3. The heating body at the eyelash clamping part of the electric eyelash curling device adopts a high-quality nickel-chromium heating wire to conduct heat energy, curls eyelash at high temperature, quickly preheats eyelash for 10 seconds, and is safe and carefree to use; the wide-space comb teeth can heat and shape the eyelashes after the mascara is applied, the eyelashes are curled up for a long time, and dense electric eyes are presented.
