The application relates to the technical field of
toothbrush control, and discloses an electric
toothbrush, which comprises a
handle cylinder, a first
machine core frame and a second
machine core frame which are detachably connected and are installed in the
handle cylinder, a
sound wave motor is arranged between the first
machine core frame and the second machine core frame, a
brush head
assembly is clamped on a driving shaft of the
sound wave motor, and a control board is arranged on one side of the first machine core frame; a switch board is arranged on one side of the second machine core frame, a micro switch for sensing the pressure of the
brush head
assembly is arranged on the switch board, a guide rail is arranged on the side wall of the first machine core frame, a sliding groove which is in sliding cooperation with the guide rail is arranged in the
handle cylinder, a convex point is arranged on the guide rail, the first machine core frame is in interference cooperation with the handle cylinder through the convex point, a shock-absorbing ring is sleeved with one end of the first machine core frame and the second machine core frame, and the shock-absorbing ring is in
abutment with the inner wall of the handle cylinder. The application simplifies the
pressure sensing structure, can reduce the manufacturing cost of the electric
toothbrush, can effectively reduce the
noise of the electric toothbrush due to the shock-absorbing and positioning effects of the shock-absorbing ring, and enhances the use experience of users.
