Description

Electric toothbrush

Technical Field

The utility model relates to the technical field of articles for daily use, in particular to an electric toothbrush.

Background

Toothbrushes are necessities of modern human life, and various toothbrushes are available on the market. The filament layout design of the toothbrush in the prior art is mainly a parallel type and a surrounding type, which does not fully consider the cleaning of the wisdom tooth area in the deep part of the oral cavity, and has a certain limitation when cleaning the inside of the oral cavity, thereby producing the electric toothbrush. The electric toothbrush generally has two forms, one is a sound wave type electric toothbrush, a vibration motor in a toothbrush handle generates high-frequency vibration to drive a toothbrush head and bristles of the toothbrush head to vibrate in a high frequency mode, the bristles of the toothbrush head vibrate in a reciprocating mode in at least one direction to clean teeth and gum, the other is a mechanical type electric toothbrush, the vibration or the rotation of the motor in the handle is converted into the rotation of the toothbrush bristles through a transmission part in the toothbrush head, the bristles of the toothbrush head do the reciprocating motion in at least one direction to clean the teeth and the gum, some toothbrushes adopt one of the forms, and some toothbrushes adopt two of the forms. To adopting the motor vibration to realize the electric toothbrush of clean tooth function, when the toothbrush head stretched into the oral cavity, the toothbrush head probably collided with the tooth, the toothbrush head at this moment is in the high frequency vibration state, can produce great impact and produce great sound simultaneously to the tooth when the toothbrush head collided the tooth, then can make gum or tooth produce painful sense to having not hard up or sensitive tooth, and then make this part of user produce the psychology that fear when brushing teeth with electric sound wave formula toothbrush, cause this part of user's abandonment even, lead to the tooth to last not to be cleaned better, and then further foster not hard up and anaphylactic symptom that bacterium or residue lead to, lead to vicious circle. Different users have different tooth brushing habits, and have different problems when using the electric toothbrush, such as toothpaste residues exist on teeth and the toothbrush after tooth brushing, or residues which do not fall out from gaps between the teeth exist in bristles, and for example, residues exist in the bristles, so that people are used to lightly rinse the toothbrush, people are used to clean the oral cavity and the toothbrush together in a water-containing mouth rinsing mode, but the toothpaste and the residue residues on the bristles and the toothbrush head are not easy to clean in a light rinsing mode and a single mouth rinsing mode, and teeth are inflamed or sensitive after a long time. In addition, the residual toothpaste and the mouthwash in the oral cavity often flow down along the toothbrush handle in the existing tooth brushing process, so that the hands of a user are wet, and the user needs to clean the toothbrush subsequently, so that the toothbrush is inconvenient to use.
