Description

Detailed Description of the Invention (a) Industrial Application Field This invention is an inhaler used to heat water to evaporate it, spray the vapor together with an inhalation liquid through a nozzle, and inhale it into the throat or the like. Regarding.

(b) Prior Art Conventionally, as an inhaler using steam, the one shown in FIG. 2 is known. This conventional inhaler 21 has a case 2
2, a suction liquid tank 23, a suction liquid nozzle 24, a steam tank 25, a steam nozzle 26, and a heater 27.

The suction liquid tank 23 is removably attached to the case 22, and contains the suction liquid 23a.

A suction liquid pipe 24a hangs down within the suction liquid tank 23. The upper end of the suction liquid pipe 24a is connected to the suction liquid nozzle 24.
It is said that

A steam nozzle 26 is provided opposite to this suction liquid nozzle 24 . The steam nozzle 26 is connected to the steam tank 25, and a heater 27 is disposed on the bottom surface of the steam tank 25, and the water W contained in the steam tank 25 is heated. Note that 28 is a cap of the steam tank 25.

When the heater 27 is energized and generates heat, the water W in the steam tank 25 is heated and steam V is generated. The steam V is ejected from the steam nozzle 26, but at this time, the suction liquid 23a is sucked up due to the Hentury effect and is ejected from the suction nozzle 24. Then, a mixture of steam and suction liquid is sprayed from the spout 22a of the case 22.

(c) Problems to be Solved by the Invention In the conventional suction liquid 21 described above, the amount of water W in the steam tank 25 is 30 to 7011I1. Although this is often considered to be the case, it takes 2 to 3 minutes after the heater 27 is energized until the steam V is generated.

In addition, when the amount of water supplied into the steam tank 25 is too large, the hot water in the steam tank 25 can be directly transferred to the steam nozzle 26.
There was a danger of it erupting.

Furthermore, even after the power is turned off, the steam tank 25
If water remained inside, it would take a long time for the spray to stop, leading to wasted inhalation fluid and the risk of burns to the user.

This invention was made in view of the above, and aims to provide an inhaler that starts spraying in a short time after turning on the power, stops spraying immediately after turning off the power, and does not spray hot water from the steam nozzle. It is said that
