Nano bubble generator for cleaning root canal of tooth and dental apparatus comprising the same

摘要

Provided are a nano bubble generator for irrigating a root canal of a tooth and a dental device including the nano bubble generator. The nano bubble generator may include a generator configured to generate nano-scale bubbles within a fluid, a nozzle connected to the generator and configured to move the fluid containing bubbles that flows in from the generator and to apply the fluid at the end of the nozzle, and an ultrasonic portion disposed in the nozzle and configured to apply ultrasonic waves to the fluid containing the bubbles so that the bubbles are maintained in a distributed form.

1. A nano bubble generator for irrigating a root canal of a tooth, the nano bubble generator comprising:
a generator configured to generate nano-scale bubbles within a fluid; a nozzle connected to the generator and configured to move the fluid containing bubbles that flows in from the generator and to apply the fluid at the end of the nozzle; and an ultrasonic portion disposed in the nozzle and configured to apply ultrasonic waves to the fluid containing the bubbles so that the bubbles are maintained in a distributed form, wherein the nozzle comprises:
a converger connected to the generator and having a decreasing cross-sectional area along a flow direction of the fluid to accelerate the fluid containing the bubbles that flows in from the generator; anda diffuser extended from the converger and having an increasing cross-sectional area along the flow direction of the fluid to decelerate the fluid containing the bubbles that flows in from the converger.
