This inhaler A is equipped with a tank 6, and the steam tank 4 is provided with a steam relief valve 7 for releasing the steam in the steam tank 4 to the outside.When discontinuing use, the steam relief valve 7 is By opening it, spraying of the inhalation liquid 3 can be prevented and the above objective can be achieved.

(Example) Reference numeral 1 denotes a main body case made of heat-resistant synthetic resin, and inside the main body case 1 there is an inhalation tank 2 containing an inhalation liquid 3 such as a medical solution, salt water, or water, and a suction tank 2 that generates steam for atomizing the inhalation liquid 3. A steam tank 4 for supplying water 5 to the steam tank 4 and a water supply tank 6 for supplying water 5 to the steam tank 4 are detachably attached, and a cover 11 having a spray guide port 9 at the tip is attached detachably to protect it from dust, etc. ing. The suction tank 2, steam tank 4, and water supply tank 6 are made of transparent heat-resistant synthetic resin such as polycarbonate so that the inside can be seen. The steam tank 4 is installed almost in the center of the main body case 1, and a heater 8 disposed at the bottom boils and vaporizes the water 5 supplied, and this steam is passed through a steam outlet 13 provided on the upper wall. Steam pipe 1 connected to
4 and is ejected from the injection nozzle 15 at the tip. The injection nozzle 15 becomes thinner toward the tip, and steam is injected at high speed. 63
is a drip prevention plate. The tip of the suction nozzle 16 is located in front of the tip of the injection nozzle 15 via an L-shaped connecting plate 17, and the suction tank is placed in the front of the main body case 1 by utilizing the ventilate effect of high-speed steam. Suction tank 2 attached to section 12
The suction liquid 3 is sucked up through the suction pipe 18, atomized, and sprayed toward the spray guide port 9. The injection nozzle 15, the suction nozzle 16, and the steam pipe 14 are made of stainless steel or heat-resistant synthetic resin, and the suction pipe 18 is a rubber pipe made of silicone rubber or the like that does not elute substances harmful to the human body for hygiene reasons. can be easily bent when installed inside the main body case 1. The suction tank 2 is vertically partitioned approximately at the center by a partition plate 19, and has a water storage section 20 in the front half so that the suction liquid 3 and the like that have become water droplets near the spray guide port 9 can be stored in the water storage section 20. . A water supply tank cap 22 is attached to a water supply port tank 21 at the upper end of the water supply tank 6, and a water supply tank cap 22 is provided with a water supply tank valve 23 and a water supply tank cap seal 24. The water tank valve 23 is designed to open when pushed in, and is normally closed by a spring 25 to prevent water 5 from leaking even when the water tank 6 is turned upside down. The water tank 6 is inserted into a water tank receiver 26 at the rear of the main body case 1 in an inverted state, and is installed in an airtight state with a water tank seal 27. Main case 1
A water storage chamber 28 is provided at the lower part of the water tank receiver 26. Water supply port 2 of water supply tank 6 of water storage chamber 28
The water storage chamber water supply port 29 communicating with the water storage chamber valve 30
is provided, and is closed by a spring 31 when the water tank 6 is not attached. The water storage chamber valve 30 is in contact with the water tank valve 23 of the water tank 6, so that the opening and closing operations are interlocked. A water supply valve 33 is provided in the steam tank water supply port 32 communicating with the steam tank 4 of the water storage chamber 28, and a certain amount of water 5 can be supplied by opening the water supply valve 33.
By closing, water 5 does not enter the steam tank 4 from the water storage chamber 28, 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 33
is provided at the lower end of the on-off valve 34 provided in the steam tank 4. The opening/closing valve 34 is also provided with a steam relief valve 7 that opens and closes a steam relief port 35 provided on the upper wall of the steam tank 4, and is linked to the water supply valve 33. The steam relief port 35, which is opened and closed by the steam relief valve 7, communicates with a steam exhaust tube 42 provided on the upper wall of the steam tank 4, and the steam relief tube 10 is routed from the steam exhaust tube 42 toward the spray guide port 9. It is set up. Therefore, the steam that passes through the steam relief port 35 and flows out into the steam relief pipe 10 does not enter the main body case 1, and is gently blown out from the spray guide port 9, so even if the steam relief valve 7 is opened inadvertently, the steam will not be released. This prevents the risk of getting burned if the product hits your hand. A water supply valve seal 36, a steam relief valve seal 37, and an on-off valve seal 38, such as silicone rubber O-rings, are attached to the water supply valve 33, steam relief valve 7, and on-off valve 34, respectively, so that an airtight state can be maintained. Water 5, steam, etc. can be removed from the main body case 1.
Make sure it doesn't leak inside. The opening/closing stopper 34 is constantly pushed up by a return spring 41 in order to interlock with the push button 40 protruding outward from the opening 39 of the cover 11, and when the push button 40 is pressed, the opening/closing stopper 34
4 is lowered to close the water supply valve 33 and the steam relief valve 7. Since the opening and closing operations of the water supply valve 33 and the steam relief valve 7 are linked in this way, when the steam relief valve 7 is closed to generate steam in the steam tank 4, backflow of high-temperature water to the water storage chamber 28 is prevented. In this way, the steam tank water supply port 32 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. A stable water supply can be provided. Further, since the water supply valve 33 and the steam relief valve 7 are provided almost coaxially, even if the internal pressure in the steam tank 4 increases due to steam generation, the internal pressures applied to each valve 33 and 7 will be applied in a direction that cancels each other out. The operating force for the push button 40 remains light. 54 is a water storage chamber vent communicating with the steam relief pipe 10. A micro switch 43 as a power switch is provided between the steam tank 4 and the push button 40, and the heater 8 is connected to a commercial power source via the micro switch 43. When the push button 40 is pressed, a micro switch 43 is turned on so that the heater 8 can be energized. In this way, the power supply is cut off at the same time as the steam relief valve 7 is opened, so that steam does not blow out continuously during the pause, and the water 5 in the steam tank 4 runs out even when the machine is paused for a long time. There is no need to put it away. The heater 8 is arranged at the bottom of the steam tank 4, and as shown in FIG. A plate-shaped heating element 45 made of a positive temperature coefficient thermistor is housed in each heating element housing part 56 of the heat dissipating plate 44, which is a formed zinc or aluminum diamond cast molded product, and electrodes on both sides of the heating element 45 are tapered. Brass electrode plates 46 are closely connected, and the outside of the electrode plates 46 is covered with an insulating sheet 47 made of heat-conductive silicone rubber. A spacer 48 is interposed between the protruding end of the heating element storage section 56 and the upper end of the heating element 45, and a presser plate 49 is arranged at the base of the heating element storage section 56. Push up the electrode plate 4 with the leaf spring 50
6 is pressed against the heating element storage section 56. The heating element housing section 56 has a tapered shape in which the width between both sides increases as it approaches the base.
The heating surface area of the heater 8 is increased, the rise time of steam generation is shortened, and the water 5 in the steam tank 4 is
can be used effectively till the end. 51 is a fixing screw, 52 is a push nut, 53 is a lead wire,
57 is a leaf spring holding plate, and 58 is a bottom plate.

Next, the operation of the water absorber A configured as described above will be explained. In FIG. 4, the cover 11 is removed, the water tank 6 is taken out, and the water tank cap 22 is removed to replenish the water tank 6 with water 5. Insert the plug 60 of the power cord 59 into a commercial power outlet. After that, as shown in the figure, when the water tank 6 is placed on the water tank receiver 26 of the main body case 1, the water tank valve 23 and the water storage chamber valve 30 inside the water tank cap 22 open, and the water tank 6 and the water storage chamber 28 are communicated with each other. Water 5 flows into the water storage chamber 28 and air flows into the water tank 6
Go inside. At this time, since the open/close tap 34 is raised and opened, the water 5 flows into the steam tank 4 through the steam tank water supply port 32, and continues until the water level reaches the same level as the water level in the water storage chamber 28. When the water storage chamber 28 becomes full, air enters from the steam release pipe 10 through the water storage chamber vent 54 and the water supply from the water tank 6 is continued until the air stops entering the water tank 6 at the specified water level a of the water storage chamber 28. Subsequently, the water level in the steam tank 4 is always kept constant. Next, when the push button 40 is pressed, the on-off valve 34 is lowered, the steam relief valve 7 and the water supply valve 33 are closed, and the micro switch 43 is turned on, as shown in FIG. 3, and the heater 8 generates heat, warming the water 5 in the steam tank 4. . When the water 5 boils, the evaporation tank 4 is filled with steam, and since the steam relief valve 7 and the water supply valve 33 are closed, steam is jetted out from the injection nozzle 15. As a result, the suction liquid 3 in the suction tank 2 is sucked up into the pipe 1.
8 to a suction nozzle 16, atomized, and ejected as mist droplets from a spray guide port 9 as shown in FIG. When the push button 40 is released in this state, the open/close valve 34 is moved upward by the return spring 41, and the steam relief valve 7 is opened to the state shown in FIG. 10 and is opened near the spray guide port 9. As a result, the steam pressure in the steam tank 4 drops rapidly and no steam is ejected from the injection nozzle 15, so that the spraying of the suction liquid 3 immediately stops. Further, as the opening/closing valve 34 moves upward, the water supply valve 33 is also opened, and water 5 is replenished from the water storage chamber 28 and the water supply tank 6 into the steam tank 4 as described above. FIG. 4 shows a state in which water supply is completed. Since this water 5 is not heated, the water temperature in the steam tank 4 decreases and the generation of steam also stops. Since the opening/closing valve 34 is interlocked with the micro switch 43, the power supply is also cut off as shown in FIG. 6, and the state returns to its original state. When the push button 40 is pressed again, the steam tank 4 is sealed again, the power is turned on, the heater 8 generates heat, and steam is generated again to start spraying.

〔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.
In this way, the spraying of the inhalation liquid can be immediately stopped without compromising safety in any way, which not only improves the usability but also prevents wastage of the inhalation liquid.
