A toothbrush that uses thermal expansion and contraction to time In the process of brushing teeth, children have problems such as the difficulty of controlling the duration and resistance to brushing. But there are safety hazards for parents to help their children brush their teeth. Some parents also use another separate device to control the time when their children brush their teeth, such as mobile phones. Therefore, the design uses the principle of thermal expansion and contraction. By adding a thermometer-like structure in the middle of the toothbrush, the liquid column is raised to the top by using the temperature of the palm. The top of the liquid column container is an animal shape. The rise time of the liquid column is just in line with the scientific brushing time. At the same time, it increases the fun and encourages children to develop a good habit of sticking to their teeth.
