Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to an improvement in a medical inhaler for general household use. A conventional inhaler of this type, which is the object of the improvement of the present invention, will be explained with reference to FIG. ■
is the main body of the inhaler, which has a removable drug cup 8 for storing the drug solution 2 in the front, and a steam tank 5 in the empty space 4 at the rear.
A heater 6 is provided on which the heater 6 is removably placed. 7 is a tank cap detachably provided on the steam tank 5, 8 is a steam pipe, and 9 is a chemical liquid pipe. A nozzle 8a at the tip of the steam pipe 8 and a nozzle 9a at the tip of the chemical liquid pipe 9 are connected to each other by a metal fitting 10. are connected so that they are facing the same direction. 1) is a main body cover having a spout 12 that spews out steam containing a chemical solution.

By the way, in the above-mentioned conventional inhaler, the chemical liquid 2 is sucked up into the chemical liquid pipe 9 by the Pentieri effect when the steam generated in the steam tank 5 is ejected from the nozzle 8a. The capacity of the tank 5 is approximately 80 cc, and it takes at least 2 to 8 minutes to boil this 39 cc of water, so there is a waiting time when using it. Further, since the steam tank 5 is sealed, the inside cannot be cleaned, and limescale accumulates during long-term use, making it unhygienic. In view of this, it is an object of the present invention to provide a medical inhaler equipped with a steam generation chamber that can be used immediately without waiting time and is easy to clean.

[Structure of the Invention] The medical inhaler of the present invention includes a removably provided medicinal solution cup for storing a medicinal solution in the front of the main body, and an evaporation chamber consisting of a dish-shaped recess provided with a heater on the bottom surface at the rear of the main body. A water storage tank is provided above the evaporation chamber, and includes a water supply hole that supplies water to the evaporation chamber, a waterway switch that opens and closes depending on the detected temperature, and a standpipe that opens into the evaporation chamber. The device is removably mounted, and is characterized in that a steam jet nozzle at the tip of a steam pipe attached to the evaporation chamber is opposed to a chemical liquid suction nozzle at the tip of the chemical liquid pipe provided in the chemical liquid cup.

Embodiments of the present invention will be described with reference to the drawings. In FIGS. 1 and 3, reference numeral 21 denotes a main body of the inhaler, and the front part of the main body of the inhaler is provided with a drug solution cup 23 that can be attached and detached to accommodate a drug solution 2Z. A dish-shaped recess is provided at the rear of the main body 21 to form an evaporation chamber 24, and a heater z5 is attached to the bottom of the evaporation chamber 24. z6 is a water storage tank that is removably placed on top of the evaporation chamber 24, and has a standpipe 27 that opens into the evaporation chamber 24.
and a waterway switch 28 that opens and closes the water supply hole 29. 30 is a steam pipe that passes through the main bodies 2, 1 and communicates with the evaporation chamber 24, and 31 is a seal backing. Reference numeral 32 denotes a chemical liquid pipe, and a chemical liquid suction nozzle 32a at the tip thereof is connected to a steam jet nozzle Boa at the tip of a steam pipe 80 by a coupling fitting 38 so as to face each other. Reference numeral 34 denotes a main body cover having a spout 35 for spouting steam containing a chemical solution.

FIG. 2 is a diagram showing the structure of the waterway switch 28, in which (a) shows a case where a shape memory alloy coil is used, and (b) shows a case where a bimetal switch plate is used. In (a), 86 is an opening/closing plate that opens and closes the nozzle-shaped water supply hole 29 of the water storage tank 26, and is urged by a spring 37 to close the water supply hole 29. Reference numeral 38 denotes a coil made of a shape memory alloy that has the property of expanding at high temperatures and contracting at high temperatures.
6 and the case 39. Therefore, when the temperature is low, the opening/closing plate 36 closes the water supply hole 29, but when the heater z5 is energized and the temperature of the evaporation chamber 24 rises, the opening/closing plate 36 closes the water supply hole 29.
6 opens the water supply hole 29 and pours water from the water storage tank 26 into the evaporation chamber 2.
Supply to 4. (B) is an embodiment of the present invention in which the water supply hole 29 is opened and closed by a piemetal opening/closing plate 40, and the evaporation chamber 24
When the temperature of the bimetal opening/closing plate 4 reaches a predetermined temperature,
0 opens the water supply hole 29 and pours water from the water storage tank 26 into the evaporation chamber 2.
Supply to 4.

The standpipe 27 maintains the pressure in the water storage tank 26 and the pressure in the evaporation chamber 24 equally, and flows from the water storage tank 26 to the evaporation chamber 24.
Facilitate water supply to.

[Effects of the Invention] Since the inhaler of the present invention has the above structure, when the heaters 2 and 5 are energized and the temperature of the heaters reaches a predetermined temperature, water in the water storage tank 26 drips into the evaporation chamber 24. evaporates immediately. Therefore, steam can be generated several tens of seconds after the heater is energized, and the water storage tank 26
By removing the inhaler, the inside of the evaporation chamber 24 can be cleaned very easily, thereby solving the problems of the conventional inhaler shown in FIG. 4 and achieving the object of the invention.
