Abstract

PURPOSE:To quickly generate steam so as to make its supply possible to medical treatment by such constitution as providing a water tank and a partitioning means and heating and evaporating water to generate steam in a boiling chamber while supplementing the water thereto from a supply water tank. CONSTITUTION:A fixed amount of water, supplied from inside a supply water chamber 25, is received to a boiling chamber 27, heated and evaporated by a heater mechanism 9. Generated steam is allowed to flow out to upper space of a partitioning plate 33 through a hole 37, steam pipe 35, hole 39, to pass through in a nozzle 4 and jetted. On the other hand, hot water collides against a baffle plate 45 and drops onto the partitioning plate 33 to flow down to the supply water chamber 25 through a hole 41. Water is successively supplied into the boiling chamber 27 through a hole 31 from inside the supply water chamber 25. Water 49 in a water tank 47 is sucked through a suction pipe 51 by jetting the steam from the nozzle 43 to generate a negative pressure, and a mixture of the steam with water is jetted in an atomized state from a jet 3 of an outer frame 1 and presented to, for instance, medical treatment.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an inhaler, and particularly to an inhaler with an improved structure of its vapor ordering mechanism.

(Prior Art) A conventional example will be explained with reference to FIG. FIG. 6 is a sectional view showing the structure of a conventional inhaler.

First, there is an outer frame 101, which has a container shape and includes a spout 103.

Inside the outer frame 101, a steam ordering section 105 and a water suction section 107 are accommodated.

The steam generating unit 105 includes a water tank 111 that stores water 109, and a heater mechanism 113 that is arranged on the bottom side of the water tank 111 and heats the water 109 in the water tank 111 to generate steam.
It is composed of a nozzle 115 and the like that ejects the generated steam.

On the other hand, the water suction unit 107 includes a water tank 119 containing water 117 and a water suction pipe 121.

According to the above configuration, the water 109 in the water tank 111 is heated by the heater mechanism 113, thereby generating steam. The generated steam is ejected through the nozzle 115.

Due to the ejector action of the steam ejected from the nozzle 115, the water in the water tank 119 is removed from the water suction pipe 121.
is sucked through. As a result, moisture is mixed into the steam, which is then jetted out from the spout 103 as steam suitable for treatment.

(Problems to be Solved by the Invention) According to the above-mentioned conventional configuration, it takes a long time from when electricity is started to be applied to the heater mechanism 113 to start treatment until the steam necessary for treatment is generated. There was a problem.

This is because the water tank 111 contains a relatively large amount of water 109 (for example, 50 cc to 60 cc), and the heating target capacity of the heater mechanism 113 is large.

The present invention has been made based on the above points, and an object thereof is to provide an inhaler that can shorten the time required to generate steam.

(II! Means for Solving II) In order to achieve the above object, the inhaler according to the present invention includes a water tank containing water, a water replenishment chamber disposed in the water tank, and a water replenishment chamber connected to the water replenishment chamber. and a partition means for dividing the boiling chamber into a small capacity boiling chamber, and the boiling chamber is heated and evaporated in the boiling chamber while water is supplied from the water replenishment chamber in a predetermined amount at a time to obtain steam. This is a characteristic feature.

(Function) First, there is a water tank, which is divided by partition means to form a water supply chamber and a boiling chamber. The capacity of the boiling chamber is smaller than that of the water supply chamber.

The boiling chamber is supplied with a predetermined amount of water from the water supply chamber, and the water is heated and evaporated in the boiling chamber to generate steam.

Instead of heating and evaporating the water in the aquarium as in the conventional system, the system heats only the water in the relatively small volume of the boiling chamber and heats it in one shot, so the time required for heating and evaporation is significantly reduced. be shortened.

(Example) A first embodiment of the present invention will be described below with reference to FIG.

FIG. 1 is a sectional view showing the overall structure of an inhaler according to this embodiment.

First, there is an outer frame 1, which has a container shape and is provided with a spout 3.

A steam generating section 5 and a water sucking section 6 are housed within the outer frame 1.

The configuration of the steam generating section 5 will be explained in detail.

First, there is an outer container 7, and a heater mechanism 9 is installed at the bottom of the outer container 7. A hollow cylindrical inner container 11 is arranged on the inner peripheral side of the outer container 7 with a space therebetween. The upper openings of the outer container 7 and the inner container 11 are closed by a screw-in lid 13.

A flange portion 15 is formed at the lower end of the inner container 11, and the inner container 11 is mounted with the flange portion 15 placed on the heating plate 17 of the heater mechanism 9 via a banking 19. There is.

An O-ring 21 is installed in the lower part of the inner container 11 above the heating plate 17. On this O-ring 21, a heat insulating plate 23 is installed as a partitioning means. This heat insulating board 23 is made of plastic such as Teflon, but is not limited thereto. This heat insulating plate 23 divides the inside of the inner container 11 into upper and lower halves.
The upper part is a water supply chamber 25, and the lower part is a boiling chamber 27.

A gap 29 is provided between the heat insulating plate 23 and the inner container 11 over the entire circumference. In addition, the 0 ring 21 has 0
A hole 31 is formed that communicates the inside and outside of the ring 21.

Therefore, the water 32 stored in the water replenishment chamber 25 is replenished into the boiling chamber 27 on the inner peripheral side of the O-ring 21 via the gap 29 and the hole 31.

By the way, the amount of water replenished into the boiling chamber 27 is
This is determined by the diameter of the hole 31 in the O-ring 21.

For example, when the amount of make-up water is increased, evaporation starts after the temperature inside the boiling chamber 27 drops once. In other words, the generation of steam becomes intermittent.

In the case of this embodiment, in order to avoid such a situation, the diameter of the hole 31 is determined so as to supply water in an amount commensurate with the amount of steam corresponding to the amount of heat generated by the heater mechanism 9.

A partition plate 33 is attached to the upper part of the water supply chamber 25. A steam pipe 35 is disposed between the partition plate 33 and the heat insulating plate 23. Holes 37 and 39 are formed in the heat insulating plate 23 and the partition plate 33 at the position of the steam pipe 35, respectively.

The steam generated in the boiling chamber 25 is guided into the space above the partition plate 33 through these holes 37, steam pipes 35, and holes 39.

Further, another hole 41 is formed in another location of the partition plate 33. Through this hole 41, the hot water spouted out together with steam is returned into the water supply chamber 25.

At the center position of the lid body 13 already mentioned, there is a steam jet nozzle 4.
The proximal end portion of No. 3 is fixed, and the tip thereof extends in the three directions of the spout of the outer frame.

A baffle plate 45 is placed directly above the hole 39 . This baffle plate 45 prevents hot water spewing out with steam from flowing into the nozzle 43.

Further, a holding cylinder 46 made of silicone rubber is inserted between the partition plate 33 and the lid 13. This holding cylinder 4
6 prevents the partition plate 33 and, by extension, the heat insulating plate 23 from lifting up.

Next is the water suction unit 6, which consists of a water tank 47 containing water 49, and a water suction pipe whose lower part is immersed in the water tank 47 and whose upper end extends to near the tip of the nozzle 43. It consists of 51.

The operation will be explained based on the above configuration.

First, a certain amount of water supplied from the water supply chamber 25 is stored in the boiling chamber 27, and this water is heated and evaporated by the heater mechanism 9.

The steam generated by heating and evaporation is passed through the hole 37 and the steam pipe 35.
, flows out into the space above the partition plate 33 through the hole 39. The steam that has flowed out is ejected through the nozzle 43.

On the other hand, the hot water collides with the baffle plate 45 and falls onto the partition plate 33. The water then flows over the partition plate 33 and flows down into the water supply chamber 25 through the hole 41.

In addition, there is a gap 29 in the boiling chamber 27 from the inside of the water supply chamber 25.
．． Water is sequentially replenished through the holes 31 of the O-ring 21 (.

The water 49 in the water tank 47 is sucked through the suction pipe 51 due to the generation of negative pressure due to the steam ejected from the nozzle 43 . As a result, steam mixed with water becomes a mist and is ejected from the ejection port 3 of the outer frame 1, and is used, for example, for treatment.

Thereafter, suction treatment is performed while repeating the same action continuously.

According to this embodiment, the following effects can be achieved.

First, the heater mechanism 9 is activated and the desired treatment can be started in a short time.

This is because the object to be heated by the heater mechanism 9 is limited to a relatively small amount of water in the boiling chamber 27.

Since the boiling chamber 27 is in a substantially liquid-tight state due to the heat insulating plate 23.0 ring 21, the generated steam will not flow back.

It has a simple structure in which the heat insulating board 23 is installed inside the inner container 11, and cleaning, maintenance and inspection work is easy, which is desirable considering the requirement that home treatment devices must be kept clean at all times. It is something.

The amount of water supplied from the water supply chamber 25 can be set to a predetermined amount by adjusting the diameter of the hole 31 of the O-ring 21. Therefore, the phenomenon of intermittent generation of steam can be avoided.

Since the lifting of the heat insulating board 23 is regulated by the holding cylinder 46, boiling in the boiling chamber 27 causes the heat insulating board 23 to rise.
3 never stands out.

The baffle plate 45 can prevent hot water droplets ejected together with steam from flowing into the nozzle 43.

Next, a second embodiment will be described with reference to FIG.

In this embodiment, the O-ring 21 in the first embodiment is
Instead, the heat insulating board 23 is placed on the backing 19 to form the boiling chamber 27, a hole 61 is formed in the heat insulating board 23, and the water flows from the inside of the water replenishment chamber 25 into the boiling chamber 27 through this hole 61. It is designed to replenish water. Further, a locking portion is formed on the wall of the inner container 11, thereby fixing the heat insulating plate 23 and preventing it from rising, and the holding cylinder 46 is omitted. The other configurations are the same as in the first embodiment,
The explanation will be omitted.

In this case, there is an advantage that the configuration is simplified.

Next, a third embodiment will be described with reference to FIG.

In this embodiment, the bunking 19 of the heat insulating plate 23
A hole 71 is formed at the position, and this hole 71 and the boiling chamber 27
A groove 73 is formed on the lower surface side of the heat insulating plate 23 (or on the upper surface side of the backing 19) so as to communicate with each other.

In this case, as in the case of the second embodiment, the structure can be simplified, and the effect of preventing backflow of steam generated in the boiling chamber 27 to the water supply chamber 25 side is enhanced.

Next, a fourth embodiment will be described with reference to FIG.

In this embodiment, the boiling chamber 27 side of the heat insulating plate 23 is formed into an inverted conical shape. In this case, reducing the volume of the portion of the boiling chamber 27 closer to the steam pipe 35 has the effect of efficiently generating steam and guiding it into the steam pipe 35. Further, by forming the heat insulating plate 23 on the water supply chamber 25 side into a conical shape, water in the water supply chamber 25 is efficiently guided to the hole 61 and flows into the boiling chamber 27. This is particularly effective when the amount of water in the water supply chamber 25 is small.

Next, a fifth embodiment will be described with reference to FIG.

In this embodiment, the partition plate 33 is formed into a conical shape, and the partition plate 33 is G-shaped so as to efficiently guide moisture to the holes 41.

Note that the present invention is not limited to the above embodiments.

For example, in each of the above embodiments, the interior of the inner container is divided into upper and lower parts, with the water replenishment chamber in the upper part and the boiling chamber in the lower part.The angle is not limited to 7 degrees, but various methods can be considered. For example, there is a case where a heater mechanism is formed on the peripheral wall of the inner container, and the center and outside of the cylinder are separated, with the center side serving as a water supply chamber and the outside serving as a boiling chamber.

Further, it is not necessarily necessary to divide the chamber into two chambers, and it may be divided into three or more chambers. For example, for one water supply room,
This is the case when two or more boiling chambers are formed.

(Effects of the Invention) As detailed above, according to the inhaler according to the present invention, the inside of the water tank is divided by the partition means to form a water supply chamber and a boiling chamber, thereby reducing the volume subject to heating and evaporation. Therefore, steam can be generated quickly and used for treatment.
