At the same time, the inner shell 112 is nested in the outer shell 111, and the inner shell 112 is bonded to an inner wall of the outer shell 111. Fixing the outer shell 111 to the inner shell 112 through an adhesive helps to simplify a connection structure, to improve the utilization rate of the internal space. In addition, electric toothbrushes are often maintenance-free, and the use of bonding connections can improve the structural strength. In some embodiments, the inner shell 112 uses a fully degradable PLA (Polylactic Acid) material, that is, a fully biodegradable PLA material. PLA has good biocompatibility and biodegradability, and can be completely decomposed into water and carbon dioxide under certain conditions, so PLA has good environmental friendliness. In some embodiments, the brush head 102 can also be made of biodegradable and environmentally friendly materials such as plant fibers, to reduce pollution to the environment. Referring to Fig. 2, an end of the inner shell 112 away from the cleaning portion 101 is a closed end 114 which is arranged in a closed manner, and the closed end 114 is integrally formed with the inner shell 112.
