Abstract

An apparatus for providing a pressurized water stream for cleaning gums and teeth includes a base unit defining a cavity. The cavity contains a pump, which may move pressurized water from a reservoir to a tip in fluid communication with the pump. The pump may be secured within the cavity by at least one vibration reduction mount. Fluid may flow from the reservoir and ultimately into the tip to provide oral irrigation and/or cleaning of the teeth, gums, and tongue. The base may include a plurality of footings that elevate the base unit above a surface supporting the base unit. Also, the base may include a basin for receiving a reservoir. The basin may include a reservoir valve initially biased to a closed position and operationally attached to the reservoir, and a tube projection connected to the base unit and opening the valve when the reservoir is received within the basin. The basin and the reservoir are configured to guide the reservoir valve adjacent to the tube projection.

Claims

1. A dental water jet device comprising

a base unit defining a cavity;

a pump chassis;

a pump contained within the cavity and mounted to the pump chassis;

a vibration reduction mount separating the pump chassis from the base unit, extending through a bottom wall of the base unit, and connecting the pump to the base unit, the vibration reduction mount comprising

a mount body; and

a slot defined on a lateral side of the mount body, wherein

a portion of the chassis is received into the slot; and

the vibration reduction mount reduces transfer of vibrations from the pump to the base unit;

a reservoir in fluid communication with the pump; and

a nozzle tip operative to deliver a stream of pressurized fluid and in fluid communication with the pump.

2. The dental water jet device of claim 1, wherein the vibration reduction mount is made of rubber.

3. The dental water jet device of claim 1, wherein the pump chassis is elevated above the inside floor of the base unit by the vibration reduction mount.

4. The dental water jet device of claim 3, wherein the vibration reduction mount further comprises

a mount head portion that extends beneath the bottom wall of the base unit.

5. The dental water jet device of claim 4, wherein the slot of the mount body is configured to receive a planar edge of the pump chassis.

6. The dental water jet device of claim 4, wherein the base unit further comprises a mount connection aperture and the mount head is disposed within the mount connection aperture securing the vibration reduction mount to the base unit.

7. The dental water jet device of claim 1, further comprising vibration dampening footings operatively attached to the base unit, wherein the footings elevate the base unit above a surface supporting the base unit.

8. The dental water jet of claim 1, wherein the vibration reduction mount extends through a bottom wall of the pump chassis.

9. The dental water jet of claim 1 further comprising a plurality of vibration dampening footings operatively attached to the base unit, wherein the footings extend through a floor of the base unit and elevate the base unit above a surface supporting the base unit.

10. A dental water jet device comprising

a base unit defining a cavity;

a pump contained within the cavity;

a pump chassis supporting the pump;

a vibration reduction mount connecting the pump chassis to the base unit, the vibration mount comprising

a mount body having at least one rounded corner;

a substantially horizontal mount aperture configured to receive a portion of the pump chassis;

a mount shaft attached to the mount body underneath the mount aperture; and

a mount head extending from a first end of the mount shaft; and

the base unit further comprises

a mount connection aperture, wherein

the mount shaft is disposed within the mount connection aperture; and

the mount body is located on a first side of the mount connection aperture and the mount head is located on a second side of the mount connection aperture;

a reservoir in fluid communication with the pump; and

a nozzle tip operative to deliver a stream of pressurized fluid and in fluid communication with the pump.

11. A dental water jet device comprising

a reservoir for fluid storage;

a base unit including a basin for receiving the reservoir;

a nozzle tip in fluid communication with the reservoir;

a pump chassis;

a pump connected to the pump chassis, wherein the pump is in fluid communication with the reservoir and the nozzle tip and the pump supplies fluid from the reservoir to the nozzle tip; and

a vibration reduction mount operatively connected to the pump chassis and the base unit and extending through a floor of the base unit, the vibration reduction mount comprising

a mount body; and

a groove defined in a lateral side of the mount body, wherein a portion of the pump chassis is received into the groove to elevate the pump chassis above the floor of the base unit.

12. The dental water jet device of claim 11, wherein the reservoir defines a curved outer surface conforming to a curved surface defined by the basin.

13. The dental water jet device of claim 12, wherein the curved outer surface of the reservoir and the curved surface of the basin permit a single position of the reservoir relative to the basin for receipt of the reservoir within the basin.

14. The dental water jet device of claim 11, further comprising at least one footing operatively connected to the base unit, wherein the at least one footing is operative to elevate the base unit above a surface supporting the base unit.

15. The dental water jet device of claim 14, wherein the at least one footing is composed of a vibration dampening material.

16. The dental water jet device of claim 11 further comprising

a reservoir valve initially biased to a closed position and operationally attached to the reservoir;

and

a tube projection connected to the base unit that opens the valve when the reservoir is received within the basin;

wherein the basin and the reservoir are configured to guide the reservoir valve adjacent to the tube projection.
