Abstract:
1. A sterilizer for dental handpieces comprising: a casing assembly having an opening formed at the front side for coming in and going out of a handpiece; a door configured such that an ultraviolet barrier incised in a radial shape opens and closes the front opening of the casing assembly; a transparent tube installed inside the casing assembly in order to be fluid-communicatively connected with the door to put a handpiece thereon; a sensor installed on the brim of the opening at the front side of the casing assembly; an ultraviolet lamp installed inside the casing assembly; a control circuit for controlling the overall operation of the sterilizer in such a manner that it opens the ultraviolet barrier when it confirms the approach of the handpiece by the sensor, closes the ultraviolet barrier after the handpiece has been entered, turns on the ultraviolet lamp for a predetermined time, turns off the lamp, opens the ultraviolet barrier again, and closes the ultraviolet barrier after the handpiece has been withdrawn; and a motor for opening and closing the door in response to a control signal generated from the control circuit.
