Abstract

The present invention relates to an oral cavity cleaning device. The oral cavity cleaning device may include an air injection portion that injects high pressure air; a cleaning liquid tank that cleaning liquid is stored therein; an acceleration portion that is connected to the cleaning liquid tank through a first pipe body and is connected to an air injection portion through a second pipe body, and draws out cleaning liquid form the cleaning liquid tank by pressure difference and injects this, if high pressure air is supplied from the air injection portion; a nozzle portion that is connected to the acceleration portion by a pipe body and makes the cleaning liquid injected by high pressure air be injected to a tooth; and a switching portion that controls the air injection portion to reduce, increase injection amount of cleaning liquid, or stop the cleaning liquid.

Claims

1. An oral cavity cleaning device, comprising:

An air injection portion that injects high pressure air;

A cleaning liquid tank that cleaning liquid is stored therein;

An acceleration portion that is connected to the cleaning liquid tank through a first pipe body and is connected to an air injection portion through a second pipe body, and draws out cleaning liquid form the cleaning liquid tank by pressure difference and injects this, if high pressure air is supplied from the air injection portion;

A nozzle portion that is connected to the acceleration portion by a pipe body and makes the cleaning liquid injected by high pressure air be injected to a tooth; and

A switching portion that controls the air injection portion to reduce, increase injection amount of cleaning liquid, or stop the cleaning liquid.

2. The oral cavity cleaning device of claim 1, wherein:

the air injection portion includes an air tank that air is stored therein; and

an air pump that is connected to a switching portion and supplies the air tank with air in a case that a switch is turned on.

3. The oral cavity cleaning device of claim 1, wherein:

the acceleration portion includes an expansion pipe portion that is formed at an end portion of the second pipe body;

a shrink pipe portion that is continuously formed with the expansion pipe portion and have a smaller space than that of the expansion pipe portion to accelerate fluid speed; and

an outlet that discharges fluid passing the shrink pipe portion at high speed.

4. The oral cavity cleaning device of claim 1, wherein the nozzle portion includes an inner side frame that surrounds an outer side of a tooth and injects cleaning liquid;

an outer frame that covers an outer side of the inner side frame to form a pipe;

an main pipe that is formed between the outer frame and the inner side frame and cleaning liquid flows therein;

a pair of branch pipes that diverges from the main pipe and is extended to both sides;

a nozzle that is respectively disposed on the branch pipe to be able to inject cleaning liquid and are arranged at an upper side, a lower side, a left side, and a right side; and

a scattering prevention protrusion that protrudes on the inner surface of the inner side frame to prevent the scattering of cleaning liquid.

5. The oral cavity cleaning device of claim 4, wherein the inner side frame includes a horizontal portion that a concave groove is formed therein to form the main pipe and the branch pipe;

and a pair of vertical portion that is extended from both sides end of the horizontal portion and an injection hole is formed to inject cleaning liquid, and a scattering prevention protrusion is protruded on an inner surface of the vertical portion to prevent the scattering of cleaning liquid.

6. The oral cavity cleaning device of claim 1, wherein the pipe body further includes a pressure wave portion and a pressure adjuster that can vary the pressure of cleaning liquid that is supplied through a pipe body or can stop cleaning liquid such that cleaning liquid is injected through the nozzle portion.

7. The oral cavity cleaning device of claim 1, wherein a pair of pipe body hook portion is further formed at a lower portion of the case, and the pipe body hook portion includes a body that is inserted into a leg that protrudes on a lower portion of the case;

and a seated portion that is formed on an upper portion of the body to have a concave shape and that the pipe body is hooked to be fixed thereon.
