[0002] Toothpaste is a paste product applied to the surface of human teeth in a frictional manner for the main purpose of cleaning. It is generally in a gel state and is usually applied to a toothbrush. With the mechanical friction of the toothbrush, it cleans the tooth surface, cleans the teeth and their surroundings, and purifies and refreshes the oral cavity. Ignoring oral hygiene will pose a huge health hazard. In modern society, more and more attention is paid to oral hygiene. With the popularization of the concept of smart home, automatic toothpaste squeezers have gradually entered the public eye.
