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.

A toothbrush system configured to be coupled to an external suction source. The toothbrush system includes a shaft with a main body with a first end and a second end, and a bristle array and a suction port arranged at the second end. The bristle array and the suction port both extend away from the shaft so that an opening of the suction port is proximal to a distal end of the bristle array. The shaft also includes a stem arranged at the first end. The stem includes a passageway that extends through the main body to provide a fluid connection to the suction port, and is configured to be coupled to the external suction source. Also, the handle is removably coupled to the shaft and includes a drive system operably coupled to the bristle array to actuate motion of the bristle array.

The present invention relates to a mouth cleaning device using incoming fluid, a mouth cleaning system comprising such device and a method for using the mouth cleaning device. The mouth cleaning device comprises: a housing extending in a longitudinal direction comprising: an incoming fluid inlet; an outgoing fluid outlet; a cleaning head with an incoming fluid outlet and an outgoing fluid inlet; and a cleaning head connector configured for connecting the cleaning head to the housing, and the cleaning head connector comprising an incoming fluid channel configured for operatively connecting the incoming fluid inlet and incoming fluid outlet, and an outgoing fluid channel configured for operatively connecting the outgoing fluid inlet and outgoing fluid outlet, wherein the cleaning head connector comprises an incoming fluid connection and an outgoing fluid connection that are provided at a connection distance in the longitudinal direction of the housing.

A dental instrument for use with a dental handpiece cleans and disinfects tooth root canals. The instrument includes a shaft and connector for releasable attachment to the handpiece, the shaft including at least a tip end, a distal portion approximate to the connector, and at least two radial protrusions extending along length of the shaft with a longitudinal groove extending between the at least two radial protrusions.

A portable oral irrigator includes a nozzle, a handle, an outer water container and an inner water container. The nozzle is at an upper end of the portable oral irrigator. The handle is below the nozzle. The outer water container is below the handle. The inner water container is below the outer water container. A sealing ring is at a bottom of the inner water container for sealing the inner water container. An annular silicone sealing member is at a joining portion of the outer water container and the inner water container. A gasket is between the outer water container and the handle. An air passable silicone seal is on the gasket. With provision of the air passable silicone seal, a raised bottom of the air passable silicone seal contracts to close its cross-shaped opening due to water pressure in the outer water container, thereby preventing leakage.
