Description

Inner structure of induction charging type voice toothbrush and induction charging type voice toothbrush

Technical Field

The utility model relates to an inner structure and the rechargeable pronunciation toothbrush of response of rechargeable pronunciation toothbrush belongs to electric toothbrush technical field.

Background

Electric toothbrushes have been accepted by the public for their effective teeth cleaning benefits, and more brands and manufacturers have added to the electric toothbrush industry. In the market segment field, sounding toothbrushes with music playing functions are increasingly popular with users, especially in the children's toothbrush market. The micro-electronic chip, the circuit board, the motor, the sound production device, the battery and the like are assembled in the electric toothbrush, and the rotation of the motor and the music playing are controlled by turning on and off the switch. But need to guarantee good user experience, the music toothbrush needs accurate structural design except that the circuit supports, guarantees to have good sound chamber and waterproof performance. However, due to the limitation of technical capability, the existing music toothbrush in the market is generally simple and crude in design, low in price, poor in sound quality and waterproof performance, and is difficult to meet the increasingly high requirements of users due to the fact that dry batteries are used more often. Therefore, the disposable dry battery is used as power, and the toothbrush does not have the repeated charging function and the induction type charging function which is unique to the high-end toothbrush.

Recently, in the field of middle and high-end electric toothbrushes, electric toothbrushes that have a sound generating function and can be repeatedly charged have appeared. Such a toothbrush sound producing device is a buzzer.
