Abstract

A massager for giving vibratory hits on a skin face. A multiplicity of stimulative projections each having an acute apex are provided on an impingement vibrating member impinging on the skin face. The impingement vibrating member is fitted with an ion electrode for energizing pointwise the minus ions on the skin face. The ion electrode is formed with an energizing projection, whereby the minus ions act pointwise on the skin face.

Claims

1. A massager for giving vibratory hits on a skin face, comprising:

an impingement vibrating member moving to and fro with respect to a skin face, said member having a hole perforated in a substantially central portion thereof;

a multiplicity of stimulative projections formed on a front surface of said impingement vibrating member and each having a substantially acute apex; and

an ion electrode, fitted to the underside of said impingement vibrating member, for energizing minus ions on the skin face, characterized in that an energizing portion projecting from a front surface of said ion electrode extends into said hole perforated in said impingement vibrating member.

2. The massager as set forth in claim 1, wherein said stimulative projections each assuming a substantially quadrangular pyramidal shape are arrayed on the front surface of said impingement vibrating member.

3. A massager as in claim 1 wherein said energizing portion is recessed below the apices on said front surface of said impingement vibrating member.

4. A massager as in claim 1 further comprising a tubular guide about said impingement vibrating member and spring means causing said guide to extend beyond said front surface of said impingement vibrating member, said guide being retractable against the force of said spring means when brought to bear against said skin face, thereby causing said front surface of said impingement vibrating member to contact said skin face.

5. The massage as in claim 1 wherein said energizing portion is recessed below the apices of the stimulative projections.
