AI Technical Summary

Problems solved by technology

It can be seen from the above technical solutions that the existing electric toothbrushes can realize automatic up and down swing brushing or can realize front and rear automatic telescopic brushing, but toothbrushes that can integrate up and down automatic swing brushing and front and rear automatic telescopic brushing functions are not common.
