Toothbrush capable of quantitatively extruding toothpaste

Technical field

The invention relates to the technical field of daily necessities, in particular to a toothbrush capable of quantitatively extruding toothpaste.

Background technique

A toothbrush is a kind of brush used to clean teeth. Generally, when tooth brushing, toothpaste is added to the toothbrush to clean the teeth, which is a must for people's daily life. However, if you carry a toothbrush and toothpaste separately during business trips or travel, on the one hand, the storage volume is too large and takes up a lot of space. On the other hand, toothpaste is easily crushed and broken, which is very inconvenient, so a portable toothbrush came into being. The portable toothbrush generally consists of a brush head and a handle having a toothpaste receiving chamber therein, wherein the handle tail is provided with a toothpaste extrusion device that can extend into the toothpaste receiving chamber. By rotating the toothpaste extrusion device, the toothpaste in the toothpaste accommodating chamber can be flowed to the brush head, and the product occupies a small space and is convenient to use. However, the prior art toothpaste extrusion device cannot quantitatively extrude toothpaste, and it is easy to squeeze too much toothpaste by accident, which causes waste of toothpaste and speeds up the consumption of toothpaste, and the toothpaste is inconvenient to be replenished when going out. There is a need in a portable toothbrush for a toothpaste extrusion device that can quantitatively squeeze toothpaste to control the amount of toothpaste extruded.
