Description

Thermal Cutting Epilator

The present invention relates to a thermally cut hair remover that removes body hair using heat generated from a hot wire.

Generally, a depilator is a means for removing hair, ie, hair, on the skin of a human body.

In particular, women are concerned about getting rid of hair that can be cosmetically unpleasant or disgusting.

Such an epilator is various, such as a shaving razor that cuts hair using a razor blade, a threshing force type hair removal machine forcibly removing hair, a high frequency type hair removal device using tweezers to remove hair, and a laser hair removal device using a laser comb.

However, such a conventional hair removal device has a problem of causing pain or damaging the skin in the process of removing body hair.

In order to solve this problem, a thermal cutting type epilator has recently been introduced, for example, Japanese Patent Application Laid-Open No. 2006-149863 (hair removal device).

In the prior art, the heating wire is operated by a contact switch. That is, since the power is turned on / off through the operation of the switch, it is not only troublesome, but also has a problem in that power is consumed unnecessarily while the switch is not turned off because the electric power consumption is large.

The present invention provides a heat cutting type epilator for removing hair using heat generated from a hot wire, the automatic switching unit generating a depilation motion signal when the friction roller rotates in contact with the skin; A signal amplifier for amplifying the epilation operation signal generated by the automatic switching unit to a recognizable level; A signal determining unit determining whether the signal amplified by the signal amplifier is an epilation operation signal; Hair removal unit for removing the hair passing through the comb through a hot wire; A position shifting part that adheres the epilation part to the skin; A power supply unit supplying driving power to the respective units; And an operation switching unit for supplying power to the epilating unit and the position moving unit by switching according to the signal applied from the signal determining unit.

The present invention can remove hair without pain and skin damage, thereby improving stability and preventing the occurrence of discomfort.

In addition, the present invention does not need to operate a separate operation switch, thereby improving usability.

In addition, the present invention, since power is supplied to the heating wire only during the depilation operation, it delays the aging and damage of the heating wire due to long time use.

In addition, the present invention can supply power to the heating wire only during the depilation operation, it is possible to prevent unnecessary power consumption.
