Description

Technical Field

[0001] The utility model relates to the technical field of epilators, in particular to an expansion mechanism and an epilator. Background Art

[0002] Nose hair can block dust, bacteria, etc. in the air, allowing the human body to inhale filtered clean air. At the same time, the cilia in the nose can also allow some bacteria to enter the stomach with mucus and be killed by stomach acid. However, too long nose hair affects one's appearance, so a trimmer is needed to trim it. The nose hair trimmer is basically the same as the principle of an electric shaver. It uses a motor to drive the blade to rotate and cut off the hair. The greater the power of the machine, the faster the blade rotates, and the better the trimming speed and effect. Similarly, the trimmer can be used to trim ear hair.

[0003] The currently used nose hair trimmer adopts a three-dimensional arched blade design to avoid damaging the nasal cavity. At the same time, it is set to an open slit to capture nose hair in any direction and length, and is equipped with a hair storage box to effectively store hair debris and increase the neatness of the device. However, its main structure is set to be cylindrical, which is convenient for entering the nasal cavity but cannot provide extended support for the nasal cavity. There is a problem of inconvenience in observation through a mirror when using it. For this reason, we propose an expansion mechanism and a hair remover. Utility Model Content
