Detailed Description

For a more clear and complete description of the technical solution of the present invention, the following description is made with reference to the accompanying drawings.

Referring to fig. 1-4, the present invention provides an electric toothbrush capable of replacing bristles 12, including a brush head portion 1, a cover 2, a brush head mounting portion 3, and a casing 4 integrally formed with the brush head mounting portion 3, wherein the brush head portion 1 is detachably mounted on the brush head mounting portion 3, the cover 2 is detachably mounted on the casing 4, the brush head mounting portion 3 includes a mounting cavity 30 and a positioning hole 31 communicating with the mounting cavity 30, the brush head portion 1 includes a base body 10 embedded in the mounting cavity 30, a positioning column 11 protruding from an end surface of the base body 10 and embedded in the positioning hole 31, and bristles 12 fixed on the base body 10.

Through the structural design of the utility model, the problem that the brush head of the electric toothbrush in the prior art is separated from the brush handle can be effectively prevented, and the effect of fixation and stability can be achieved when the brush hair 12 can be replaced.

In the present embodiment, the positioning hole 31 is adapted to the positioning column 11, and the base 10 is adapted to the mounting cavity 30. The base 10 can be just completely embedded into the mounting cavity 30, and the positioning column 11 slightly protrudes from the end surface of the positioning hole 31. Through setting up locating hole 31 with the cooperation of reference column 11 base member 10 with the cooperation between the installation cavity 30 realizes that brushhead portion 1 can dismantle and install in brush head installation department 3, and convenience of customers changes brushhead portion 1.
