A feature of the present invention is that the chamber 10 is hermetically sealed and provided with an air pump 20. The water in the chamber 10 is supplied by pressurizing and supplying air into the chamber 10 sealed by the air pump 20. It is to push out and discharge.

The chamber 10 is provided with a space for storing water therein, the inlet 11 is formed in the upper portion to receive water, the outlet 12 is formed in the lower portion is discharged water, the air supply pipe ( 21 is communicated so that the air is supplied into the chamber 10 by the air pump 20.

The inlet 11 is to be opened and closed when the stopper 13 is installed and can be opened and closed, and to be sealed when using a tooth cleaner.

The outlet 12 is provided at the bottom so that water can be discharged even at a low water level, and the filter 14 is provided adjacent to the outlet 12 so that foreign matters are not ejected to the washing nozzle 30.

The air pump 20 is a manual air pump 20 using a reciprocating motion of a piston that is generally used, the user can be driven by hands or feet.

That is, the air pressure greater than atmospheric pressure acts on the surface of the water tank by the compressed air generated as the manual air pump 20 is operated, so that the water in the water outlet 12 and the washing water supply pipe ( Since it is injected from the washing nozzle 30 via 31), no power is required.

In addition, the air pump 20 is provided with a check valve 22 is supplied with air from the outside and pumped in a predetermined direction, so that the air in the chamber 10 does not flow back when the air pump 20 does not drive the chamber (10) is to be sealed.

The washing water supply pipe 31 is bent in a coil shape to be able to increase the length when used, the control valve 32 is to be installed to adjust the flow rate.

The washing nozzle 30 is in communication with the washing water supply pipe 31 to eject water through the tip, the handle 33 is formed so that it can be used to hold by hand.

Therefore, the water is stored in the chamber 10 through the inlet port 11, the inlet port 11 is sealed with a stopper 13, and then the air pump is opened while the check valve 22 is opened and the control valve 32 is closed.
