摘要:
An oral irrigator including a handle, a tip, and a pump at least partially received within the handle and fluidly coupled to the tip. The pump includes a pump body defining a pump chamber, an inlet valve regulating fluid flow into the pump chamber, an outlet valve regulating fluid flow out of the pump chamber, a piston, and a linkage operably coupled to the piston and a drive shaft of a motor. The linkage translates rotational movement of the drive shaft into movement of the piston in first and second directions within pump chamber. When the piston moves in the first direction, the inlet valve opens, allowing fluid to flow into the pump chamber, and the outlet valve closes. When the piston moves in the second direction, the inlet valve closes and the outlet valve opens, allowing fluid to flow out of the pump chamber.
