Description

The present invention takes up the field of daily necessities, and specifically is a foldable electric toothbrush.

Toothbrushes have a great influence on people's lives as daily necessities. When brushing teeth with an existing toothbrush, the orientation of the toothbrush must always be adjusted. However, I still can't brush every part of my teeth. In particular, the head portion of the toothbrush is fixedly installed and is not suitable for the demand for toothpaste. Also, when people go out or travel, the toothbrush they carry requires a relatively large space, and mold is likely to grow. Therefore, it is necessary to design a bendable electric toothbrush. When brushing your teeth, you can adjust the orientation of the toothbrush, brush out of reach of general toothbrushes, make it convenient for people to go out, and also have a self-cleaning function.
