Abstract: In one embodiment, an oral irrigator including a reservoir, a tip fluidly connected to the reservoir, a motor having a drive shaft, and a pump. The pump includes a pump body including a pump inlet fluidly connected to the reservoir and a pump outlet fluidly connected to the tip, a spiral pinion gear including a plurality of pinion gear teeth that curve along their length, and a spiral driven gear including a plurality of driven gear teeth that mesh with the pinion gear teeth. The pump also may include a connecting rod eccentrically connected to the driven gear and a piston and received within the pump body. Movement of the drive shaft causes the pinion gear to rotate, causing the driven gear to rotate, translating the connecting rod and moving the piston laterally within the pump body to pull fluid from the reservoir and push the fluid to the tip.

Abstract: The present disclosure relates to an oral irrigator. In one embodiment, the oral irrigator includes a motor, a pump body, a connecting rod, and a diaphragm seal. The connecting rod is at least partially received within the pump body and is movably connected to the motor such that the motor moves the connecting rod between a first position and a second position within the pump body. The diaphragm seal is connected to the connecting rod and the pump body and deforms from a first orientation to a second orientation as the connecting rod moves from the first position to the second position.
Abstract translation: 本公开涉及一种口腔冲洗器。 在一个实施例中，口腔冲洗器包括马达，泵体，连杆和隔膜密封件。 连杆至少部分地容纳在泵体内并且可移动地连接到马达，使得马达使连杆在泵体内的第一位置和第二位置之间移动。 当连接杆从第一位置移动到第二位置时，隔膜密封件连接到连接杆和泵体，并从第一方向变形到第二方向。

Abstract: 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.

Abstract: An oral irrigator includes a drive assembly, a pump assembly, and a flexible membrane seal. The drive assembly is received within a housing. The pump assembly is positioned at least partially within a pump chamber. The pump assembly includes a piston and a connecting rod coupled to the drive assembly, the connecting rod movable between first and second positions through operation of the drive assembly. The flexible membrane seal extends from an interior surface of the pump chamber to the connecting rod to fluidly seal an open end of the pump chamber. The flexible membrane seal deforms from a first orientation to a second orientation as the connecting rod moves from the first position to the second position.
