Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Figure 1-4 An electric toothbrush head of a first embodiment is shown. Such as Figure 1-4 As shown, the electric toothbrush head of the first embodiment includes a brush bar 1, a bracket 2, an eccentric wheel 3 and a drive shaft 9, the drive shaft 9 is installed in the brush bar 1 through the bracket 2 and can rotate freely, and the front end of the drive shaft 9 is equipped with an eccentric wheel 3. The motor drives the transmission shaft 9 to rotate, and then drives the eccentric wheel 3 to move linearly. The brush plate 5 is installed on the front end of the brush rod 1 through the shaft hole connection device. A motion conversion device is arranged between the brush plate 5 and the eccentric wheel 3 for The linear motion of the eccentric wheel 3 is converted into the reciprocating swing motion of the brush disc 5 around its own rotating ...

Abstract

The invention provides an electric toothbrush head which comprises a brush rod (1) and a brush disc (5), wherein a transmission shaft (9) is mounted in the brush rod; an eccentric wheel (3) is mounted at the front end of the transmission shaft; the brush disc is mounted at the front end of the brush rod through a shaft hole connection device; a motion conversion device is arranged between the brush disc and the eccentric wheel and used for converting the linear motion of the eccentric wheel into reciprocating swing motion of the brush disc around a rotary shaft (7) of the motion conversion device; the motion conversion device comprises an L-shaped sliding sleeve (8), a protruding shaft (5b) arranged on the back of the brush disc and a smooth eccentric shaft (3a) arranged at the front end of the eccentric wheel; a first movable hole (8a) and a second movable hole (8b) vertical to each other are formed in the L-shaped sliding sleeve; the first movable hole is in movable fit with the protruding shaft; the second movable hole is in movable fit with the smooth eccentric shaft. The invention also provides an electric toothbrush with the electric toothbrush head. The electric toothbrush head has the characteristics of long service life, good safety, stable operation, low noise and the like.

Description

technical field [0001] The present invention relates to an electric toothbrush, more specifically, an electric toothbrush head, and an electric toothbrush using the electric toothbrush head. Background technique [0002] In the field of electric toothbrush technology, there are a variety of technical solutions to achieve electric cleaning, and each technical solution has different performances in cleaning energy efficiency, cost, reliability, safety and other indicators. The electric toothbrush needs toothpaste to complete the cleaning process. The toothpaste is composed of abrasives mixed with various compounds and organic solvents, which accelerates the wear and chemical corrosion of the metal and plastic moving parts of the electric toothbrush, and slightly shortens the life of the toothbrush. Seriously, small parts will be damaged and fall off in the mouth, causing safety problems. Therefore, the success of the structural design of an electric toothbrush head must be ba...
