Abstract

An electric toothbrush device with a built-in shrapnel assembly includes a toothbrush head, a brush assembly and an electric motor. A built-in shrapnel assembly is disposed in the cavity, and the built-in shrapnel assembly is disposed to abut against the drive shaft. The built-in shrapnel assembly includes an arch-shaped protrusion arching towards the drive shaft. A side of the drive shaft facing the arch-shaped shrapnel assembly defines a tooth groove matching the arch-shaped protrusion, the drive shaft presses against the arch-shaped protrusion, to cause the arch-shaped protrusion to undergo an elastic deformation, to thereby securely fix the drive shaft in the cavity. The electric toothbrush head device has the advantages of strong practicality, high stability, and long-term use without deformation, by providing the shrapnel assembly inside to increase the clamping effect.
