Abstract
A portable ultrasonic cosmetic applicator for spraying makeup/sterilants onto the body or face. Eliminates the use of noisy compressors, pressurized cylinders and air lines. Characterized by a small, lightweight device without the use of cumbersome attachments or pumps. Produces a fine misty spray that is easily applied with a smaller and more uniform droplet size than commonly used spray equipment or hand applicators, thus reducing the amount of unused cosmetics.
Claims3
A cosmetic applicator comprising:
- an ultrasonic device to atomize a cosmetic liquid held in a delivery well via a vibrating distal tip, the device comprising:
- a longitudinal main body having a proximal end and a distal end;
- a rear cover located at the proximal end;
- a frontal control mechanism, wherein the delivery well is located on the frontal control mechanism at the distal end of the main body;
- a liquid delivery orifice at a distal end of the control mechanism,
- the delivery well having a valve relief hole at a bottom of the well configured to meter the cosmetic liquid onto the vibrating distal tip, wherein the vibrating distal tip being located at the distal end of the frontal control mechanism;
- a valve switch plate assembly comprising:
- a longitudinal valve switch plate having a proximal end and a distal end;
- a valve pin attaching to the valve relief hole;
- a roll pin configured to pivot the valve switch plate on a vertical axis defining a fulcrum;
- a spring biasing the valve switch plate against the main body of the ultrasonic device,
- a piezoelectric ceramic at the proximal end of the main body;
- and
- wherein the piezoelectric ceramic is connected to a circuit board and batteries located at the proximal end of the main body.
