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.

The present disclosure relates to a pumping assembly, a piston pump and a water flosser. The pumping assembly includes: a cylinder, at least two chambers with different inner diameters being provided in the cylinder; a piston mechanism successively extending through the at least two chambers, the piston mechanism being in slidable cooperation with walls of the chambers, and a gap being formed between a sidewall of part of the piston mechanism and the walls of the chambers; and a drive mechanism connected to the piston mechanism, the drive mechanism being configured to drive the piston mechanism to move.

An oral irrigator may include a body, a reservoir connected to the body, a tip connected to the body, a motor positioned within the body and including a drive shaft, a pinion gear connected to the drive shaft, a driven gear engaged with the pinion gear, a pump body positioned within the body and defining a pump chamber for receiving fluid from the reservoir, a piston positioned within the pump body, wherein the piston slidably engages an interior surface of the pump body to form a fluid-tight seal, and a connecting rod including a first end connected to the piston, a second end eccentrically connected to the driven gear, and a shaft extending from the first end to the second end. The shaft includes a first rib and a second rib spaced apart from the first rib along a length of the shaft.

An apparatus for dental irrigation may be provided to project fluid onto the surfaces of, and the interproximal spaces between, a user's teeth and gum-line. The apparatus may comprise two hollow U-shaped manifolds having orifices located on their interior faces used as fluid jets. The manifolds may be connected, at a central point of reflection, by a rotating inlet joint which supplies the fluid flow. When placed in the user's mouth, the apparatus may be designed to receive the top and bottom sets of teeth in each corresponding U-shaped manifold, with orifices configured to provide fluid jets aligned towards the lingual and buccal side of the teeth. The orifices may be staggered to provide staggered fluid flow. A user's teeth may be cleaned with a controlled fluid flow by moving the apparatus in a sweeping motion between each set of rear molars.
