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.
