An oral irrigator including a handle through which fluid flows to a tip. Fluid flows to the tip during irrigate mode, and fluid flow may be interrupted by selecting a pause mode. The handle includes a mechanically controlled actuator for selecting the pause mode. The actuator may include a rack gear operably connected to a pinion gear formed on a valve spool inside the handle. The valve spool may include a ball that blocks fluid flow to the tip during pause mode but not during irrigate mode.
1. An oral irrigator handle comprising a housing;a fluid inlet into the housing;a fluid outlet from the housing;a valve body positioned between the fluid inlet and the fluid outlet, the valve body defining a valve inlet in fluid communication with the fluid inlet of the housing and a valve outlet in
1. An oral irrigator handle comprising a housing;a fluid inlet into the housing;a fluid outlet from the housing;a valve body positioned between the fluid inlet and the fluid outlet, the valve body defining a valve inlet in fluid communication with the fluid inlet of the housing and a valve outlet in fluid communication with the valve inlet and in selective fluid communication with the fluid outlet of the housing;a valve spool positioned within the valve body;a sealing assembly connected to the spool and movable therewith; anda mechanical pause control actuator that interfaces with the valve spool, wherein actuation of the mechanical pause control actuator moves the valve spool from an open position to a paused position within the valve body, wherein in the paused position, the sealing assembly seals the valve outlet to interrupt fluid flow from the valve inlet to the fluid outlet of the housing. 2. The oral irrigator handle of claim 1, wherein the valve spool comprises a pinion gear extending from an outer surface of the valve spool. 3. The oral irrigator handle of claim 2, wherein the mechanical pause control actuator comprises a rack gear, wherein the pinion gear forms an engagement with the rack gear, such that when the mechanical pause control actuator is actuated the engagement between the rack gear and the pinion gear converts a first type of motion to a second type of motion. 4. The oral irrigator handle of claim 3, wherein the mechanical pause control actuator is actuated by moving linearly relative to the valve body. 5. The oral irrigator of claim 4, wherein the first type of motion is linear motion and the second type of motion is rotational motion. 6. The oral irrigator handle of claim 5, wherein rotation of the pinion gear rotates the valve spool to move the valve spool to the paused position. 7. The oral irrigator handle of claim 1, wherein the sealing assembly further comprises a biasing element connected to the valve spool; anda ball seated on a top end of the biasing element such that the biasing element biases the ball towards the valve body, wherein in the paused position of the valve spool, the ball blocks a passageway between the fluid inlet and the fluid outlet. 8. The oral irrigator handle of claim 1, wherein the valve spool further comprises: an annular recess; anda sealing component adjacent the annular recess to provide a seal between the handle along an interface of the valve spool. 9. An oral irrigator comprising a reservoir;a pump in fluid communication with the reservoir;a handle in fluid communication with the pump, comprising a housing, a handle inlet into the housing and a handle outlet from the housing; anda pause switch assembly connected to the handle comprising an actuator slidably connected to the handle and movable between a first position and a second position; anda valve assembly connected to the actuator and positioned between the handle inlet and the handle outlet, the valve assembly comprising: a valve body received within a cavity of the handle, the valve body defining a valve chamber having a valve inlet in fluid communication with the handle inlet and a valve outlet in fluid communication with the valve inlet and the handle outlet; anda spool rotatably connected to the actuator and received within the valve chamber; anda sealing assembly connected to the spool and rotatable therewith; whereinmovement of the actuator from the first position to the second position rotates the spool of the valve assembly from an open position to a paused position; andin the paused position, the sealing assembly seals the valve outlet to prevent fluid flow between the valve inlet and the handle outlet. 10. The oral irrigator of claim 9, wherein the pause switch assembly is independent from the pump. 11. The oral irrigator of claim 9, wherein the actuator comprises a plurality of actuator gear teeth extending from a first interior side;the spool comprises a plurality of spool gear teeth extending from a first surface thereof, wherein the spool gear teeth mesh with the actuator gear teeth to translate a linear motion of the actuator to a rotational motion of the spool within the valve chamber. 12. The oral irrigator of claim 11, wherein the spool gear teeth extend in an arc pattern along the first surface of the spool. 13. The oral irrigator of claim 12, wherein the first interior side is a linear edge. 14. The oral irrigator of claim 9, wherein the valve assembly further comprises at least one U-cup received around the spool, wherein the at least one U-cup defines a seal between walls of the valve chamber and the spool. 15. The oral irrigator of claim 9, wherein the sealing assembly comprises a spring connected to the spool; anda ball seated on a top end of the spool, wherein the spring biases the ball against a wall of the valve chamber. 16. The oral irrigator of claim 15, wherein the ball and the spring are received within a cavity defined on an outer surface of the spool. 17. A handle for an irrigating device comprising a housing in fluid communication with a fluid source and comprising a housing inlet and a housing outlet;a tip removably connected to the housing and in fluid communication with the housing outlet; anda pause switch connected to the housing and configured to selectively interrupt fluid flow from the housing outlet to the housing inlet, the pause switch comprising a switch movable along a longitudinal axis of the housing between a first position and a second position;a valve body received within the housing, the valve body defining a valve inlet in fluid communication with the housing inlet and a valve outlet in fluid communication with the valve inlet and the housing outlet;a valve member rotatably coupled to the switch and received within the valve body; anda sealing assembly connected to the valve member and rotatable therewith; whereinmovement of the switch from the first position to the second position rotates the valve member and the sealing assembly from an open position to a paused position; andin the open position the fluid flows uninterrupted from the housing inlet to the tip; andin the paused position the sealing assembly seals the valve outlet such that the fluid flow is blocked between the housing inlet and the tip. 18. The handle of claim 17, wherein the sealing assembly comprises a ball and a spring.
