Description

Electric eyelash curler

Technical Field

The utility model relates to a makeup product, in particular to an electric eyelash curler.

Background

In daily life, due to the needs of performances, life and the like, many women can use the mascara to be matched with the eyelash clip to roll the eyelashes into an arc shape, so that the effect of raising the eyelashes with big eyes is achieved. However, eyelash can easily fall off by using the eyelash curler, which is inconvenient for long-term use, and after the mascara is brushed, the eyelash can be dried after waiting for a period of time, which is easy to make up.

The electric eyelash curler can make eyelash curler and shape, solving the above problem to a certain extent. The traditional electric eyelash curler generally comprises a hollow brush head, an exposed heating wire and an exposed temperature sensor are arranged in the brush head, and the detection part of the temperature sensor is abutted against the heating wire and used for detecting the temperature of the heating wire and feeding back the temperature to a main control to adjust the output power of the heating wire.

Although the electric eyelash curler solves the problem of curling eyelashes to a certain extent, eyelash cannot be thickened and lengthened, and the effect needs mascara to be solved. The electric eyelash curler cannot dip mascara for the following reasons:

1. the brush head is the brush head of the traditional electric eyelash, and the mascara can not be dipped and used by the brush head;

2. a temperature sensor is needed, the detection result of the temperature sensor is easily influenced by the environment, the data feedback is inaccurate, and the eyelash curler cannot be cleaned due to the existence of the heating wire and the temperature sensor; in addition, the temperature sensor also needs to be matched with corresponding electronic elements to work together, the PCB cost is high, and the layout of the PCB is large, so that the miniaturization of products is not facilitated;

3. the heating wire and the temperature sensor are required to be wrapped by the brush head, so that the eyelash curler can not be detached and cleaned; the residual heat generated by the heating wire is easy to solidify and remain on the brush head, so that the nickel-chromium heating wire is easy to dissipate heat unevenly to cause temperature abnormity, the brush head is made of nylon materials, the heat of the heating wire needs to be transferred through the brush head, and the curling effect is not obvious;

4. the liquid mascara is easily adhered to the brush rod to affect the use of the eyelash curler, and the liquid mascara is accelerated to be solidified by the residual heat of the heating wire;
