Sound wave vibration structure of electric toothbrush

Abstract

The invention discloses a sound wave vibration structure of an electric toothbrush, comprising a driving rod capable of transmitting by vibration and a vibration source micro motor capable of generating resonance output, wherein the driving rod is assembled in a cavity on the neck of a toothbrush head body; the micro motor is arranged in an inner cavity of the driving rod and close to the toothbrush head body and can drive the toothbrush head body by the driving rod and resonate the toothbrush head body by sound wave; and the rear end of the driving rod is connected with a bracket in a handle. In the invention, the vibration source is separated from a main body control board, so that the damage of the control board under high-frequency vibration can be effectively reduced. The invention has the advantages of simple structure, reasonable design, convenient carrying and the like and is an ideal instrument for cleaning and protecting teeth.

[0002] Toothbrush is the most commonly used tool for cleaning teeth. It is used to remove bacteria, tartar and small debris attached to the teeth. It can prevent periodontal diseases and protect people's oral hygiene and dental health. Toothbrushes on the market now Various and different structures, such as Chinese patent, patent number: ZL 200620102401.9 discloses a sonic vibration toothbrush, including a brush head with bristles, a brush neck rod and a vibration part that doubles as a brush handle. The vibration part is provided with a vibration joint , connected to the brush neck through the vibration joint, the vibration source motor, the vibration rod and the main body electric board and other components are all set in the handle that doubles as the vibration part. The main defect of this toothbrush is that the vibration source and the main control board are set together It is easy to be damaged under high-frequency vibration, and the handle doubles as a vibration part to increase the vibration of the body, so it cannot achieve the desired effect
