Description

Electric toothbrush

Technical Field

The invention mainly relates to an article for daily use, in particular to an electric toothbrush.

Background

The toothbrush is used for cleaning teeth

The brush for teeth, meanwhile, the toothpaste is added on the brush to clean the teeth when the brush is used for brushing teeth generally, and the habit is basically the same all over the world.

The shape of the toothbrush is basically not changed from ancient times to present, the traditional toothbrush is generally a straight handle, and the head is made of fibers such as nylon, duPont wires and the like. In hundreds of years from the appearance of toothbrushes, people have not made continuous innovation, and from the aspect of integral appearance and appearance, the toothbrush has no great breakthrough, and from the original completely straight handle and different periods, handles with different bending shapes appear, a brush head is an ellipse, a square head, a diamond shape and the like, and a bone handle toothbrush, a metal mobile phone toothbrush, a plastic handle and the like are changed in materials.

In recent years, due to the development of technology, toothbrushes have revolutionized, and electric toothbrushes (ultrasonic toothbrushes are an upgrade of electric toothbrushes) have appeared on the basis of common manual toothbrushes. Although the electric toothbrush has a much thicker handle portion in its exterior than a general toothbrush, the overall exterior is almost the same. In principle, the electric toothbrush drives the brush on the brush head to vibrate by means of the vibration of the motor on the toothbrush handle, and the vibrating brush replaces hand force to push the brush head to clean teeth, so that the teeth cleaning efficiency is greatly improved.

With the development of the times, the pressure of work is high, the rhythm of life is fast, getting up to brush the teeth every day is a time-consuming work, so that the speed of brushing the teeth is accelerated, and the teeth can be more effectively brushed. When people go out for travel, people are inconvenient to carry the toothbrush and the toothpaste (the quality of the toothpaste used in hotels is poor). Limb injuries or defects, inconvenient mobility of the elderly, inability of the patient to get up, etc., seem to be a very simple task at ordinary times, which is a complicated affair for them.

Our science and technology has developed into space and sea bottom of ten thousand meters beyond the imaginable situation before, and the most common daily living article toothbrushes that we use everyday have not been a great breakthrough.
