Abstract: An electric toothbrush comprises a support frame, a drive frame, and a motor. The support frame is provided with a hollow part. The drive frame is elastically connected to the support frame through an elastic arm. The drive frame is positioned in the hollow part. The drive frame is spaced apart from the support frame. An upper end of the drive frame has a drive shaft connector configured to be connected to a toothbrush head. The motor is arranged in the drive frame. An output shaft of the motor is connected with a vibrating hammer. The motor is rotatable to drive the drive frame to swing or vibrate relative to the support frame so that the drive shaft connector can drive the toothbrush head to swing or vibrate.

Abstract: The present disclosure provides a double-tank oral irrigator. The double-tank oral irrigator includes a rotary valve, a first tank, a second tank, a water guide pipe, and a pump assembly. The rotary valve includes an outlet part, a first inlet part, a second inlet part, and a valve core. The rotation of the valve core enables adjustment of the sealing degree of the valve core to the first inlet part and the second inlet part. The first inlet part is connected to the first tank, the second inlet part is connected to the second tank, and one end of the water guide pipe is connected to the outlet part. The pump assembly is connected to the other end of the water guide pipe and a spray outlet of the oral irrigator.

Abstract: The present invention pertains to a water flosser pump body structure and a water flosser, the water flosser pump body structure comprises a housing, a water pump assembly, a transmission assembly and a driving assembly, the water pump assembly comprises a pump body, an inlet valve member, an outlet valve member and an elastic diaphragm, the pump body has a water flow cavity therein, the inlet valve sheet and the water flow cavity form an inlet channel, and the outlet valve sheet and the water flow cavity form an outlet channel; and the transmission assembly rotates to drive the elastic diaphragm to repeatedly deform so as to cause a change in pressure in the water flow cavity, thereby realizing a pumping and jetting process of the water flosser for flossing teeth.

Abstract: The invention relates to an electric toothbrush handle and an electric toothbrush. The electric toothbrush handle comprises: a shell in the inner cavity of which at least one light emitting element is arranged; and a display interface arranged on the outer side of the shell and covering the light emitting element; wherein the display interface is provided with a mark in a set shape at a position corresponding to each light emitting element; the light of the light emitting element is capable of penetrating through the display interface so that the mark is visible. With the mark formed on the display interface, the machining process of the electric toothbrush handle is simplified, and the electric toothbrush with the electric toothbrush handle can effectively prevent water ingress.
