Background

The ultrasonic toothbrush is a novel toothbrush which usually adopts a magnetic suspension motor as a power source to drive a toothbrush head to vibrate according to a designed frequency so as to clean teeth. The working principle of the toothbrush is that the toothbrush head is driven to swing up and down at a high speed by means of the high-speed movement of the micro motor to generate mechanical vibration, ultrasonic frequency vibration taking sound waves as energy is generated, and the toothbrush can penetrate into parts which are difficult to reach of a common toothbrush. However, most of the ultrasonic electric toothbrushes on the market have some structural defects, for example, glue is filled around the inner and outer parts of the button to form a waterproof structure, which can only achieve a waterproof level of 7, and when the water volume is large and the water contact time is long, water can seep into the interior of the brush handle from a fine gap, so that internal electronic components are damaged. Meanwhile, the sealing structure formed by the glue pouring mode can interfere with the key, so that the problem that the key is easy to malfunction is solved. In addition, the brush handle and the brush head are usually made of hard glue or only partially made of soft glue, so that the brush handle and the brush head are easy to collide with teeth when in use.

Preferably, a convex hull is provided on the handle housing, with the head of the power button being embedded in the convex hull to collectively form a fully enclosed finished key.

Preferably, a key hole is provided in the handle housing, and the head of the control button protrudes from the key hole to form the finished key.

Or at least two convex hulls (how many buttons are provided) are arranged on the brush holder shell, and the head of the power button and the head of the control button are respectively embedded in the corresponding convex hulls to respectively form completely closed finished keys.

Furthermore, the outer surface of the brush handle shell is distributed with reticular anti-slip lines, so that the brush handle is more comfortable to hold and has better anti-slip effect.

The utility model discloses a design into the triplex with the waterproof construction of button part, the button contact cooperation on inside flexible glue spare and the PCB board promptly, the middle part is by a hardware and the cooperation of inside flexible glue spare, and the glue filling forms the rubber coating layer again in the outside, and the triplex combines in proper order to make the waterproof grade of toothbrush can reach 8 grades, still can avoid traditional button to adopt inside and outside glue filling mode to lead to the easy problem of malfunctioning of button when reaching perfect waterproof. In addition, handle portion and brush head portion adopt integral type flexible glue cladding respectively, can promote the comfort level of use, avoid the stereoplasm plastic to collide with the tooth, and handle portion flexible glue both can further improve whole water-proof effects, can make again to grip more comfortable.
