Claims

A method of resetting a pause control mechanism of a mouth irrigator comprising:
providing a mouth irrigator with a handle having a bi-stable pause control element;
turning on the oral irrigator to allow fluid flow through the fluid channel of the handle of the oral irrigator;
enabling fluid flow through a valve in the mouthwash handle by operating the valve via the bistable pause control element;
compressing the elastic device from a first position to a second position;
locking the elastic device in the second position via a locking mechanism;
and releasing the locking mechanism by placing the handle of the mouthwash on a stand or turning the mouthwash off.

3. The step of expanding said resilient device from said second position to said first position and setting said bistable pause control element to inhibit fluid flow after releasing said locking mechanism. 1. The method according to 1.

A mouth irrigator system having a mouth irrigator with a mouth irrigator handle having a housing, the housing having a cavity disposed therein, the cavity having a pause control assembly, the pause control assembly comprising: the control assembly
a valve;
a slider coupled to the valve for movement between a first position and a second position and further comprising a first protrusion;
a first portion extending in a first direction and having a first end and a second end, the first end contacting a first protrusion of the slider; a return having a second portion extending in two directions and having a third end and a fourth end and further having a throughbore for receiving a valve body, said second end of said first portion; a return in which the third ends of the second portion are connected together;
and a stopper that has an open position and a closed position and prevents movement of said return in a third direction opposite said first direction.

The pause control assembly is configured such that a first position of the slider corresponds to a closed condition of the valve and a second position of the slider corresponds to an open position of the valve, the slider moving from the first position to a When the return is moved to the second position, the return is moved from the first position to the second position, and when the return is moved to the second position, the stopper engages and fixes the fourth end of the return. 4. The oral irrigator system of claim 3, wherein the oral irrigator system is configured to:

4. The oral irrigator system of claim 3, wherein said pause control assembly further comprises a resilient device biasing said return in said third direction opposite said first direction.

the pause control assembly further includes a hinge having a first hinge portion disposed on the valve body and a second hinge portion disposed on the stopper;
4. The oral irrigator system of claim 3, wherein the hinge allows the stopper to rotate in a first rotational direction and a second rotational direction opposite the first rotational direction.

7. The mouthwash of Claim 6, wherein the stopper further comprises a first portion extending from the second hinge portion in the first direction and a second portion extending from the second hinge portion in the third direction. system.

further comprising a valve body with a second biasing element for biasing the first portion of the stopper in the second direction;
when the return is in the second position, the stopper rotates about the hinge in the first rotational direction and engages a fourth end of the return to secure the return in a locked state;
the first portion of the stopper further has a catch projecting in the first direction and a ledge projecting in the second direction, and when the return is in the locked state and the stopper is in the second position, the ledge applies force in the first direction while the catch applies force in the second direction;
8. A mouth irrigator system according to claim 7.

4. The oral irrigator system of claim 3, further comprising a stand that receives the oral irrigator handle and engages the stopper.

the stand has a magnet that biases the second portion of the stopper; or the stand has a mechanical protrusion that engages the second portion of the stopper.
10. A mouth irrigator system according to claim 9.

A mouth irrigator system having a mouth irrigator with a handle, the handle having a housing having a cavity disposed therein, the cavity comprising:
a fluid channel through which fluid flow moves in a first direction substantially parallel to a first axis when the oral irrigator is in the ON state;
a valve that inhibits and permits, respectively, said fluid flow through said fluid channel when in a closed state and an open state;
a pressure plate that moves in a second direction orthogonal to the first direction or in a third direction opposite the second direction when the flow of the fluid increases the pressure in the fluid channel;
an elastic device that compresses in the second direction or the third direction;
a gated pathway piece having a body, said body comprising:
a first channel disposed within the body and extending in the second direction or the third direction and having a first end and a second end;
a second channel disposed within the body and extending in the first direction at a first angle with respect to the first axis and having a third end and a fourth end; and a third end of said second channel integrally connected to each other.

the handle
a slider that moves from a first position to a second position, the first position and the second position corresponding to closed and open states of the valve, respectively;
a guide pin disposed within the cavity of the mouthwash handle, the guide pin traveling within the first and second channels of the gated channel piece;
a tab fixedly attached to the slider, the tab having a third channel extending in the second direction or the third direction and slidably engaging the guide pin; the fluid flow in the fluid channel produces a first force on the pressure plate in the second direction or the third direction to transition the oral irrigator to an unlocked state;
12. The oral irrigator system of claim 11.

In the unlocked state, the slider moves from the first position to the second position, the slider moves the guide pin along the second channel of the gated pathway piece, and from the first position to the second channel. 13. The oral irrigator system of claim 12, wherein transition of the slider to the second position corresponds to transition of the valve from the closed state to the open state.

when the mouthwash is turned off, the slider moves from the second position to the first position, the slider moves the guide pin along the second channel of the gated pathway piece; 13. The oral irrigator system of claim 12, wherein transitioning the slider from the second position to the first position corresponds to transitioning the valve from an open state to a closed state.

13. The oral rinse of Claim 12, wherein in an OFF state, the guide pin travels further within the first channel of the gated pathway piece from the second end to the first end to transition to a locked state. vessel system.
