This invention relates to an inhaler in which a vapor relief valve is provided in the tank.

[Background technology]

In a conventional water absorber (7V), as shown in Fig. 1 (Japanese Utility Model Publication No. 56-51866), water (5) supplied into the steam tank (4) is heated by a water absorber (8) and steamed. is generated, and this steam is injected from the injection nozzle Qf9' to inhale liquid (3) such as a chemical liquid stored in the water absorption tank (2)'.
) is sucked up through the suction tube to the suction nozzle a→', atomized, and sprayed as mist droplets from the atomizing tube (9)' to be inhaled into the oral cavity. However, since the mouth is always open when inhaling, the user often stops using the device due to fatigue and to regain breathing control.For this reason, it is necessary to stop the injection of steam from the injection nozzle 01', but the power switch is turned off. Even if it is turned off, the heater (8)' is sufficiently heated, so steam is generated in the steam tank (4)' and the steam injection does not stop. There was a problem of wasting the liquid (3).It is possible to remove the septum inside the steamer (4)', but the beef septum is superheated by the steam and cannot be touched directly. It is dangerous and also
If the 13IJ is removed, high-temperature steam, hot water, etc. will blow out and it is dangerous.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a water absorber that is convenient to use because it can safely and freely interrupt spraying of an inhalation liquid even during use, and can prevent wastage of the inhalation liquid.

[Disclosure of the invention]

(Configuration) The inhaler of the present invention has an inhalation tank (
2), a steam tank (4) that generates steam to atomize the inhalation liquid (3) in the inhaler (2), and a steam tank (4).
) and a water supply tank (6) that supplies water (5) to the steam tank (4).
) is provided with a steam relief valve (7) that releases the steam inside the device to the outside, and when discontinuing use, the vapor relief valve (7) can be opened to prevent the inhalation liquid (3) from being sprayed. The above objectives were achieved.

(Example) fli is a main body case made of heat-resistant synthetic resin, and inside the main body case f1) is an inhalation liquid (3) such as a medical solution, salt water, or water.
), a steam tank (4) that generates steam for atomizing the suction liquid (3), and a water tank (6) that supplies water (5) to the steam tank (4). 0＠Person tank (2), steam tank (4), and water supply, which are removably attached and covered with a cover αη equipped with a spray guide (9) at the tip to protect them from dust, etc. tank(
6) is a zero-steam tank (made of transparent heat-resistant synthetic resin such as polycarbonate that allows the interior to be seen).
4) is installed almost in the center of the main body case (1), and the water (5) is supplied by the drainer (8) located at the bottom.
) is boiled and vaporized, and the steam is injected from the injection nozzle at the tip through a steam pipe α → that communicates with a steam outlet (end) provided in the earthen wall. The injection nozzle aQ becomes narrower toward the tip, and steam is injected at a high speed. Ifi3+ is a mold prevention board. The tip of the suction nozzle σ is positioned through the injection nozzle (L-shaped connecting plate 0'I in front of the tip of l), and the main body case f1 is
The suction liquid (3) from the suction tank (2) attached to the suction tank mounting part α-gong at the front of the + is sucked up through the suction pipe (to), atomized, and sprayed toward the atomizing hydrocarbon (9). The injection nozzle (g), the suction nozzle 0→ and the steam pipe 0→ are made of stainless steel or heat-resistant synthetic resin, and the suction pipe (to) is made of silicone or other material that does not emit substances harmful to the human body for hygiene reasons. The suction tank (2) can be easily bent when the suction tank (2) is installed inside the main body case (1). The suction tank (2) is vertically partitioned approximately in the center by a partition plate.
The front half is a water storage part (E), and the inhalation liquid (3) fattened into water droplets near the spray tube (9) can be stored in the water storage part (E). Water supply port (c) at the top of the water tank (6)
A water tank seal is attached to the water tank + sep (a), and a water tank valve (to) and a water tank sep seal (c) are installed on the water tank + sep. Water tank valve (
) is designed to open when pushed in, and is normally closed by a spring (c) to prevent water (5) from leaking even if the water tank (6) is turned upside down. Water tank (
6) is inserted into the water tank holder (E) at the rear of the main body case +11 in an inverted state, and is installed in an airtight state with the water tank seal (A). A water storage chamber (c) is provided below the water tank holder (c) of the main body case (1). The water supply port of the water tank (6) of the water storage chamber (C) is connected to the water supply port of the water storage chamber (C).The water supply port of the water storage chamber (C) is equipped with a water storage chamber valve, which can be closed by a spring button when the water supply tank (6) is not attached. That's what I do. The water storage chamber valve (to) is in contact with the water tank 9F of the water tank (6), so that the opening and closing operations are interlocked. A water supply valve (
A certain amount of water (6) can be supplied by opening this water supply valve (B3), and a water storage chamber (C) can be supplied by closing it.
Water (5) does not enter the steam tank (4), and only the water (5) supplied into the steam tank (4) can be vaporized, so that steam can be efficiently generated. This water supply valve is provided at the lower end of the on-off valve provided in the steam tank (4). As an example of an opening/closing valve, N is also provided with a steam relief valve (7) that opens and closes a steam relief port (to) provided in the earthen wall of the steam tank (4), and is linked to the water supply valve. The steam relief port (2), which is opened and closed by the steam relief valve (7), communicates with the steam exhaust pipe (2) installed in the earthen wall of the steam pit (4). A steam release pipe (10) is installed from the steam release port (5) towards the spraying system (9).Therefore, the steam passing through the steam release port 5) and flowing out into the steam release pipe (10) is It does not enter the main body case f1+,
Since the spray gas is blown out slowly from the spray tube (9), even if the steam relief valve (7) is closed inadvertently, the danger of steam hitting your hands and causing burns can be prevented. Attach a water supply valve seal such as an O-link made of silicone (a trowel, a steam relief valve seal (37), and an on-off valve seal) to the water supply valve (33), steam relief valve (7), and on-off valve, respectively. It is possible to maintain an airtight state to prevent water (5), steam, etc. from leaking into the main body case f1). An example of an opening/closing stopper is a push button (401) protruding outward from the opening (39) of the cover 01), which is constantly pushed up by a return spring (4υ). 341 is lowered to close the water supply valve (83) and steam relief valve (7).In this way, the water supply valve is closed.

Since the opening and closing operations are linked with the air relief valve (7), when the steam relief valve (7) is closed to generate steam in the steam tank (4), high temperature water is prevented from flowing back into the water storage chamber (c). The water supply port in the water storage chamber can be closed, while the steam relief valve (7) can be opened to release the air and steam inside the steam tank (4) to the outside when water is being supplied, even if there is a slight difference in water level. Water can always be stably supplied to the steam tank (4). Also, the water supply valve (33) and steam relief valve (7)
Since the valves are located almost coaxially, even if the internal pressure in the steam tank (4) increases due to steam generation, each valve @31
The internal pressures applied to F71 are applied in directions that cancel each other out, and the operating force for the push button remains unchanged and only requires a light operating force. The figure shows the water storage chamber vent communicating with the steam release pipe (101).A microswitch 0□□□ as a power switch is installed between the steam tank (4) and the lead press. ) The heater (8) is connected to the commercial power supply via the push button (4).When the push button is pressed, the micro switch (4) is turned on so that the heater (8) can be energized. Since the power supply is cut off when the valve (7) is opened, steam does not continue to blow out during periods of rest, and the steam tank (4)
The water inside (5) never runs out. heater(
8) is located at the bottom of the steam tank (4), and as shown in Figure 5, the cross section is approximately an inverted U that forms the lower wall of the steam tank (4).
A plate-shaped heating element made of a positive temperature coefficient thermistor is placed inside each heating element housing part. The heating element (4) is housed, the tapered brass electrode plate part is tightly connected to the electrodes on both sides of the heating element (44), and the electrode plate (4 (
2) is constructed by covering the outside with an insulating sheet [η] made of heat conductive silicone com. A spacer (481) is interposed between the protruding end of the heating element storage part (■) and the upper end of the heating element (4 parts), and a presser plate (0) is placed at the base of the heating element storage part (5 parts). , this holding plate α9) is pushed up by a leaf spring (60) to press the electrode plate f4B+ against the heating element housing part (@).The width between both sides of the heating element housing part (■) increases as it approaches the base. Because it has a tapered shape,
The heating surface area of the heater (8) is large and the rise time for steam generation is short, which may cause the water (5) in the steam tank (4) to
can be used effectively till the end.
The hole is a fixing screw, (64 is a bush nut, the link is a lead wire, the hole is a leaf spring holding plate, and the bottom is a bottom plate.

Next, the operation of the water absorber (A) configured as described above will be explained. In Fig. 4, remove the cover 0υ and remove the water tank (6).
Remove the water tank inner sep (c) and replenish the water tank (6) with water (5). Plug the Brata β1 of the power cord (9) into a commercial power outlet. After this, as shown in the figure, place the water tank (6) on the water tank holder (E) of the main body case +11, and the water tank valve (2) and water storage chamber valve (to) inside the water tank middle cover (2) will open. The water supply tank (6) and the water storage chamber (E) communicate with each other, water (5) flows into the water storage chamber (C), and air enters the water supply tank (6).

At this time, the stopcock (goods) has risen to the top and is open, so the water (6
) passes through the steam tank water supply port 6'4 to the steam tank (4).
The flow continues until the water level reaches the same level as the water level (into the water storage chamber). When the water storage chamber @ is full of water, the air flows through the steam release pipe (10
) Enter through the water storage room vent (54I) into the water storage room (c)
Water continues to be supplied from the water tank (6) until air stops entering the water tank (6) at the specified water level (a).
The water level in the steam tank (4) is always kept constant. Next, when the push button (40) is pressed, the open/close valve @4 opens as shown in Figure 3, and the steam relief valve (7) and water supply valve (33) close.
The switch (43) is turned on and the steamer (8) generates heat, warming the water (5) in the steamer (4). Water +51-+6
(When it boils, the evaporation tank (4) is filled with steam, and since the steam relief valve (7) and water supply valve (33) are closed, steam is ejected from the injection nozzle α. This causes the suction tank (2) to The suction liquid (3) is sucked up to the suction nozzle 01 through the suction pipe (I8), atomized, and ejected as mist droplets from the spray tube (9) as shown in FIG.

When the push button (40) is released in this state, the open/close valve moves upward by the return spring 1), the steam relief valve (7) opens and becomes the state shown in Figure 4, and the steam flows through the steam relief port (35). The steam is released from the steam outlet (4 holes), through the steam relief pipe (10), and into the vicinity of the spray tube (9).As a result, the steam pressure in the steam tank (4) decreases rapidly, and the injection nozzle (tube) )
Since no steam is ejected from the inhalation liquid (3), the spraying of the inhalation liquid (3) immediately stops. In addition, by moving the open/close valve (goods) upward, the water supply valve (3) also opens, and the water storage chamber (c) and water tank (6) open.
More water (6) is replenished into the steam tank (4) as described above. FIG. 4 shows a state in which water supply is completed. This water (5) is not heated, so the steam tank (
4) The water temperature inside will drop and the generation of steam will stop. Note that the opening/closing valve is linked to a micro switch (4 (support)), so as shown in Figure 6, the power is also cut off and the valve returns to its original state.If you press the button again, the steam tank (4) will open. It is sealed again, the power is turned on, the heater (8) generates heat, steam is generated again, and spraying begins.

〔Effect of the invention〕

In the present invention, the steam tank that sucks up the suction liquid in the suction tank and generates the steam to be sprayed is provided with a steam release valve that releases the steam in the steam tank to the outside, so that the steam can be released even during use. By opening the valve, the internal pressure in the steam tank rapidly decreases and the atomization of the inhalation liquid by steam can be interrupted, and in this way, the atomization of the inhalation liquid can be stopped immediately without compromising safety in any way. Not only is it convenient to use, but it also prevents wastage of inhalation fluid.
