Structure of hairless toothbrush

Abstract

The present invention provides a structure of hairless toothbrush, which includes an ultrasonic oscillator and a circuit switch-control component. The ultrasonic oscillator is consisted of a longitudinal metal sheath combined with at least an ultrasonic oscillation sheet. The ultrasonic oscillator is further sheathed with an external sheath equipped with a U-shaped sheath portion. The circuit switch-control component is connected with the ultrasonic oscillator through a spiral circuit wire. The ultrasonic oscillator and the circuit switch-control component can be further assembled in a storage case. When the ultrasonic oscillator is held in the mouth between the upper and lower lips through the U-shaped sheath portion of the external sheath, the oscillation waves generated by the ultrasonic oscillator in the mouth propagate uniformly and stably through the water in the mouth to the whole inner wall of mouth chamber, tongue, and every tooth for achieving comprehensive and through cleaning and sterilization, while providing lighter and easier operation.

Description

technical field [0001] The invention relates to a hairless toothbrush structure that can directly and stably output ultrasonic waves and transmit them evenly, and can comprehensively and thoroughly clean and sterilize the inner wall of the oral cavity, the tongue and each tooth. Background technique [0002] Generally, common toothbrushes on the market are used to brush with force by holding the hand, and the bristles are used to remove the dirt on the surface of the teeth. Not only is the operation of lifting the hand brushing very tiring; the brushing angle cannot penetrate deep into the gaps between teeth or local The dead corners are not easy to clean completely, and it is often necessary to further cooperate with dental floss, interdental brushes and other difficult-to-operate tools; and because the bristles are in direct contact with the teeth and gums, once there is a wound or inflammation on the inner wall of the oral cavity or the gums, it will be damaged by the bris...

AI Technical Summary

Problems solved by technology

[0015] Based on the above facts, how to eliminate the shortcomings of the existing structure cited above, such as incomplete cleaning, difficult use control and easy use fatigue, sour mouth, and water leakage in the mouth, are the key points to be solved by the present invention.
