Description

High-amplitude electric toothbrush

Technical Field

The application relates to the technical field of electric toothbrushes, in particular to a high-amplitude electric toothbrush.

Background

The electric toothbrush can make the brush head generate high-frequency vibration by the rotation or vibration of the motor core, instantly decompose toothpaste into fine foam to go deep into the slit between teeth for cleaning, can promote the blood circulation of the oral cavity by the vibration of the brush hair, and has massage effect on the gum tissue.

Currently, electric toothbrushes are classified into a rotary type, in which teeth are cleaned manually by rotation of a toothbrush head, and a vibration type, in which toothpaste is decomposed into fine bubbles by high frequency vibration transmitted to the toothbrush head by a motor, and the fine bubbles are penetrated into gaps between teeth to clean the gaps between the teeth.

The vibration type toothbrush is more complicated and higher in price. The vibrating toothbrush is internally provided with an electrically driven vibrating motor which can lead the brush head to generate high-frequency swing perpendicular to the brush handle direction.

The prior art is deficient in that the oscillating type toothbrush oscillates at a very small amplitude, typically about 5 mm each, up and down, and the maximum oscillation amplitude of the prior art is 6 mm, and the tooth cleaning ability is insufficient, and thus needs to be improved.

Insert the spliced pole 4 in the spliced eye, insert the connecting hole with the output shaft 11 of motor 10 in, accomplish electric toothbrush's equipment, starter motor 10 can use, because the interference fit of spliced pole 4 and spliced hole lets the spliced pole 4 and the spliced hole between be connected inseparabler, and because the conical setting of spliced pole 4 and output shaft 11, grafting operation is more convenient.

The toothbrush rod 2 of the present application is mainly made of carbon fiber material with the elastic modulus of 200-700 GPa. In the first embodiment, a 480Gpa elastic modulus carbon fiber toothbrush rod 2 is selected. A large number of experiments verify that the amplitude of the 480Gpa carbon fiber toothbrush rod 2 with the elastic modulus can be improved by 30%. Through chooseing for use of carbon fiber toothbrush pole 2, can let toothbrush head 3 produce bigger amplitude at the vibration process of motor 10, let the clean effect of toothbrush better.
