Description

FIELD

The present disclosure belongs to the technical field of shavers, in particular related to cooling/heating shavers.

BACKGROUND

Shaving, commonly known as beard shaving, involves removing objects from the surface with a knife. Beards generally refer to the hair growing on the upper lip, chin, face, cheekbones or neck of a man. However, when people pick up shavers, psychological satisfaction may be accompanied with physical pain, because a bloody wound is scratched by a blade. Now, these troubles can be completely under control. In the past 150 years, people have invented safety razors, removable blades, electric shavers and shaving cream.

When electric shaver is working, a large amount of heat may be generated between blades due to the high-speed relative rotation and friction between blades in a cutting unit, causing temperature rise of the cutting unit. When skin is in contact with the cutting unit, such high temperature will cause discomfort of skin.

Before shaving, the skin needs hot compress to soften the beard and skin for easy shaving. During and after shaving, apply ice compress on the skin to harden the beard and relieve the pain brought by shaving at the same time. However, shavers on the market do not have the effects of both hot and cold compress at the same time, which cannot meet the shaving needs of users, and the use experience is mediocre.
