Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an inhaler used for treating inflammation of the respiratory system.

[Technical background of the invention and its problems] Inhalers have been known from Japanese Utility Model Publication No. 50-34549 and other publications, but their closed evaporation containers require a large amount of water to be inhaled over a fairly long period of time. By heating this large amount of water, it takes a long time for the water to start evaporating due to the heating.

In other words, conventional inhalers have the inconvenience of being difficult to use when someone needs to inhale.

In addition, since hot water is essential for obtaining steam for blowing out the inhalation liquid in an inhaler, care must be taken to prevent boiling water from blowing out, regardless of how the user handles the inhaler.

[Purpose of the invention]

The purpose of the present invention is to start blowing out the steam necessary for inhalation as soon as possible, and to prevent hot water from blowing out on its own, thereby facilitating safe use and providing nine inhalation benefits.

[Summary of the invention]

That is, the present invention provides for storing an air-displacing type drop-type water supply tank, which has a water inlet at the lower end for regulating the water level in the container, in a nine-tight evaporation container to which a heater is attached, and which can be freely inserted and removed. ), the amount of water heated by the heater is limited to a small amount to shorten the time until evaporation, and to prevent hot water from flowing into the steam jet pipe regardless of the tilt of the main body case. It is characterized by what it did.
