Description

  The present invention relates to a cosmetic brush device for removing dirt on the skin such as the face.

  Conventionally, there is one that rotates a brush (for example, Patent Document 1).

  In the cosmetic brush of Patent Document 1, a circular brush is divided into an inner portion and an outer portion close to the center, and these are separately attached to the rotating shaft of the inner and outer double structure. By manually moving the rack and pinion gear mechanisms, the inner and outer rotating shafts rotate in opposite directions.

As a result, the inner part and the outer part of the brush are reversed in the reverse direction, so that the entire brush is superior to those rotating in the same direction, and when the brush changes from normal rotation to reverse rotation, Since the hair ends stand, it can be said that the cleaning effect is better than that rotating only in one direction. However, since the power was manual, the frequency of reversal was limited, and the effect was naturally limited.
