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. 1
is the main body of the inhaler, which has a removable drug cup 3 for storing drug solution 2 in the front, and a steam tank 5 in the empty space 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 1z that jets 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 vent cherry effect when the steam generated in the steam tank 5 is ejected from the nozzle 8a. The capacity of the steam tank 5 is approximately 80 cc, and there is a drawback that it takes at least 2 to 8 minutes to boil this 80 cc of water.

The present invention aims to eliminate this drawback by providing a medical inhaler equipped with a steam tank that has no waiting time and can generate steam within tens of seconds after turning on the power switch. The purpose is to provide

[Structure of the Invention] The medical inhaler of the present invention is provided with a removably attached medicinal solution cup for storing a medicinal solution at the front of the main body, a steam tank having a heater on the bottom at the rear of the main body, and a steam tank having a heater on the bottom. A waterway switch for opening and closing a water supply hole of a water storage chamber for supplying water is configured to operate in conjunction with a power switch, and a steam passage is provided for communicating a water storage tank provided above the water storage chamber with the steam tank, It is characterized in that a steam jetting nozzle at the tip of a steam pipe attached to the steam tank 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 FIG. 1, reference numeral 21 denotes a main body of the inhaler, and a medical solution cup z3 containing a medical solution 22 is detachably provided in front of the main body of the inhaler. Main body 2
Behind 1 is a steam tank 2 with a heater z5 attached to the bottom.
4 is a provision.

26 is a water storage chamber 2 formed outside the steam tank 24
7, and communicates with the steam tank z4 through a communication pipe z8. A water supply hole 29 supplies water from the water storage chamber 27 to the steam tank 24, and is equipped with a waterway switch (operating rod) 80.

Reference numeral 81 denotes a steam pipe led out from the steam tank 24, and a steam jet nozzle 31a at the tip thereof is connected to a chemical suction nozzle 82a at the tip of the chemical liquid pipe 8z so as to face each other by a coupling fitting 88.

Reference numeral 84 denotes a main body cover having a spout 85 for spouting steam containing a chemical solution.

FIG. 2 shows the relationship between the waterway switch (operating rod 80) and the power switch. One end of the operating rod 80 is attached to the tip of a switch lever 88 to which a movable contact 86a of a power switch and an iron piece 87 are attached.

The switch lever 88 is rotatably supported by a fulcrum 89 between the middle thereof and the operating rod 80.
On the opposite side is a spring 40 which acts to push it up to the position indicated by the dotted line. 86b is a fixed contact of the power switch facing the movable contact 36a, 41 is a magnet provided at a position facing the iron piece 37, and 42 is the switch lever 8.
This is the 8th pick.

Next, its effect will be explained. Switch lever 88 is spring 4
0, the movable contact 86a is always pushed up to the position indicated by the dotted line, and the movable contact 86a is separated from the fixed contact 36b. Further, the operating rod 80 is lowered and its tip closes the water supply hole z9.

Now, when the knob 42 is pressed and the switch lever 38 is pushed down from the dotted line position to the solid line position against the spring 40, the contact point 8
6 a s 86 b closes, and the operating rod 80 rises to open the water supply hole 29 .

The switch lever 38 is held in that position by the magnet 41 adsorbing the iron piece 37 and is energized, and water drips from the water supply hole 29 onto the heated bottom plate of the steam tank 24 and immediately evaporates. The communication pipe z8 maintains the pressure in the steam tank 24 and the pressure in the water storage tank 26 equally, thereby smoothly supplying water from the water storage tank 26 to the steam tank 24.

FIG. 8 shows an embodiment of the invention in which a solenoid valve 48 is used in the waterway switch. This solenoid valve 48 is always connected to the water supply hole 29.
is closed, but when it is energized by turning on the power switch, the water supply hole 29 opens and the water in the water storage chamber 27 is turned into steam.
supply to.

[Effects of the Invention] As described above, in the inhaler of the present invention, when the power switch is turned on, water in the water storage chamber 27 is poured into the water supply hole 2 onto the bottom plate of the steam tank z4 heated by the heater 25.
9, so steam can be generated several tens of seconds after the power switch is turned on. Therefore, the problems of the conventional inhaler shown in FIG. 4 are solved and the object of the invention is achieved.
