Detailed Description

The invention will be described in further detail with reference to the following detailed description and accompanying drawings: referring to fig. 1 to 4, the electric toothbrush includes a handle 1, a bracket 2 is fixedly disposed in the handle 1, a fixing seat 3 is inserted into a front end of the handle, a transmission shaft 4 for connecting a toothbrush head is fixed at one end of the fixing seat 3, the transmission shaft 4 extends out of the handle, and the transmission shaft 4 is used for connecting the toothbrush head, so that vibration energy is transmitted to the toothbrush head along the transmission shaft 4. A vibration motor 5 is fixedly arranged in the fixed seat 3.

3 one ends of fixing base are inserted and are established in support 2 to be provided with on fixing base 3 and keep off ring 30, 2 terminal surfaces of support with it has flexible pad 6 to keep off to compress tightly between the ring 30, it has sealing ring 7 and sealing washer 8 to have set gradually the interval along handle tip to afterbody direction on the lateral wall of fixing base 3, sealing washer 2 is provided with the twice, in the above-mentioned structure, stabilizes fixing base 3 through the elastic connection between twice sealing washer 2 and the 1 inner wall of handle for fixing base 3 can reset when taking place the beat under vibrating motor 5's effort, and in addition, through the setting of flexible pad 6, makes the noise that produces between fixing base 3 and the support 2 because the interaction force is reduced, makes the leakproofness between fixing base and the handle improve greatly through the cooperation of sealing ring 7 and the 1 inner wall of handle.

A ring wall 10 extending downwards is formed on the inner wall of the front end part of the handle 1, and the ring wall 10 and the retaining ring 30 abut against each other. The retaining ring 30 is circumferentially provided with a protrusion 300, the lower end of the annular wall 10 is provided with a limiting groove (not shown in the drawings), and the protrusion 300 is located in the limiting groove and is in clearance fit with the limiting groove. In the above structure, if an excessive torque is applied to the brush head connected to the transmission shaft 4, the protrusion 300 and the limiting groove are engaged with each other, so that the angle of the brush head is not excessively deflected.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The foregoing embodiments and description of the invention have been provided in the present application for the purpose of illustrating the principles of the invention and is subject to various changes and modifications without departing from the spirit and scope of the invention. All such variations and modifications are intended to be within the scope of the claimed invention.
