小さく形成されている。 In FIG. 1, 11 is an operating section such as a pedal;
2 is a water pipe with a water nozzle section 13 for discharging water attached to its tip; 14 is a solenoid valve for opening and closing water provided in the middle of this water pipe 12; and 15 is this solenoid valve 1.
This is a needle valve (or flow rate adjustment valve) provided in the middle of the water pipe 12 on the downstream side of 4 [a position closer to the water nozzle portion 13 side]. Reference numeral 16 indicates a medicinal solution tank for storing undiluted gargling solution, that is, a medicinal solution;
4, which is an electric pump that is operated with a chemical liquid nozzle part 18 for discharging chemical liquid close to the water nozzle part 13 at its tip, and whose other end is located in the middle of a chemical liquid piping 19 located in the chemical liquid in the chemical liquid tank 16. It is provided. Reference numeral 20 indicates a needle valve (or flow rate adjustment valve) provided in the middle of the chemical liquid piping 19 between the electric pump 17 and the chemical liquid nozzle portion 18, and 21 represents a chemical liquid piping between the needle valve 20 and the chemical liquid nozzle portion 18. 19 is a pipe for returning a chemical solution, one end of which is communicated with the other end located in the chemical tank 16; 22 is a solenoid valve for returning a chemical solution provided in the middle of this pipe 21; 23 is turned on by the operating section 11; , the limit switch is turned off, and the water opening/closing solenoid valve 1
4. Electric pump 17 and solenoid valve 2 for returning chemical solution
It is electrically connected to 2. The solenoid valve 14 for opening and closing the water is always closed, and the solenoid valve 22 for returning the chemical solution is always open. Further, the inner diameters of the water nozzle portion 13 and the chemical liquid nozzle portion 18 are narrowed, and the inner diameter of the chemical liquid return pipe 21 is larger than that of the chemical liquid nozzle portion 18, so that the pipe resistance is extremely small.

液の吐出も停止する。 In the above configuration, by pressing the operation part 11, the limit switch 23 is turned on, the solenoid valve 14 for opening and closing water is opened, and the solenoid valve 2 for returning the chemical solution is turned on.
2 is in the closed state, and at the same time the electric pump 17 is driven. As a result, water is discharged from the water nozzle part 13, and at the same time, the electric pump 17 sucks up the chemical liquid in the chemical liquid tank 16 into the chemical liquid piping 19 and discharges it from the chemical liquid nozzle part 18, so that the water and the chemical liquid are mixed and used as a gargle. It is used as a. At this time, the electromagnetic valve 22 for returning the chemical liquid is closed, so the chemical liquid sucked up by the electric pump 17 does not flow through the pipe 21 for returning the chemical liquid and return to the chemical liquid tank 16. By releasing the pressing force of the operating section 11, the limit switch 23 is turned off, the solenoid valve 14 for opening and closing the water is closed, the solenoid valve 12 for returning the chemical solution is opened, and the electric pump 17 is stopped at the same time. By opening the solenoid valve 22 for returning the chemical solution in this way, the residual pressure in the electric pump 17 is released to the side of the pipe 21 for returning the chemical liquid, which has a small piping resistance, and the residual pressure in the electric pump 17 causes the chemical liquid to come out from the electric pump 17. flows into the chemical liquid return pipe 21 side and returns to the chemical liquid tank 16. Therefore, at the same time as the discharge of water from the water nozzle portion 13 is stopped, the discharge of the chemical liquid from the chemical liquid nozzle portion 18 is also stopped.
