Abstract
A bypass flow assembly of an oral irrigator is provided. The oral irrigator may include a handle positionable between a first mode and a second mode and a valve assembly including a bypass valve movable between first and second positions and an inlet valve movable between open and closed positions. The first position of the bypass valve may be associated with the first mode of the handle and the second position of the bypass valve may be associated with the second mode of the handle, such that the bypass valve moves from the first position to the second position when the handle is positioned in the second mode and remains in the second position until the handle is positioned in the first mode. The inlet valve may move between the open and closed positions when the bypass valve is positioned in the first position and the second position.
