[0002] In recent years, with the increase in the birth rate and people's living standards, more and more children have oral problems. Dental caries and periodontitis have become one of the most common diseases in children, troubling children and parents. Childhood is the growth period of teeth. It is very necessary to pay attention to the protection of good teeth and the prevention of periodontal diseases during this period. However, many children often have oral problems such as dental caries because they love sweets and do not develop good brushing habits. At the same time, because children cannot get positive incentives during brushing, and the discomfort caused by toothbrushes and toothpaste in the mouth is very strong, children are very resistant to brushing their teeth. Some children who are forced to brush their teeth every day often regard brushing their teeth as a chore to deal with and always do it hastily. Therefore, children often have a vicious cycle in dealing with brushing their teeth, and cannot get a good solution to the problem. At present, there is an urgent need for a toothbrush device that can make children feel a sense of accomplishment in the process of brushing their teeth, so that children can get a positive incentive in the process of brushing their teeth, make brushing teeth interesting, promote children to love brushing their teeth, thereby solving the oral problems that are easy to occur in children at present, and help children develop a good brushing habit and protect children's dental health.
