Description

[Detailed explanation of the idea]

[0001]

[Field of Industrial Application] The present invention relates to an injection nozzle for an inhalation type thermotherapy device that atomizes heated steam and injects it into the nostrils.

[0002]

BACKGROUND ART Conventionally, as an inhalation type thermotherapy device that injects steam into the nostrils, one disclosed in Japanese Patent Publication No. 2-57431 has been known.

[0003] In the thermotherapy device that inhales steam into the nostrils, the injection surface of the heated steam at the upper end of the injection nozzle (passage 13 in the publication) is formed horizontally.

[0004]

[Problems to be solved by the invention] However, because the upper end of the injection nozzle of the conventional inhalation type thermotherapy device is formed horizontally, the above-mentioned particles rise inside the injection nozzle and are injected from the opening at the upper end. During the process, some of the steam comes into contact with the outside air and turns into water droplets, which accumulate in the opening at the top of the injection nozzle and are pressed by the rising steam one after another, causing the water droplets to splash and make a loud noise. There was a problem in that it made a loud noise that was very unpleasant.

[0005] The present invention aims to provide an injection nozzle in an inhalation type thermotherapy device that aims to solve the above-mentioned conventional problems.

[0006]

[Means for Solving the Problems] In the present invention, the injection nozzle tightly fitted and fixed to the lid of the housing of the inhalation type thermotherapy device has an inner diameter of the vent hole that is larger at the lower end and gradually becomes smaller toward the upper end. The above-mentioned problem was solved by adopting a method in which the upper end surface of the ventilation hole is formed as a sloped portion.

[0007]

[Function] According to the present invention having the above-mentioned configuration, the steam which has partially turned into water droplets upon contact with the outside air is vigorously injected upward through the ventilation hole and diffused. Even if water droplets form and adhere to the upper end surface of the vent, they flow downward along the slope.

[0008]

[Example] An example of the implementation of the present invention will be described in detail based on the drawings.
A heat conductive plate 2 made of stainless steel is fixed to the center of an inner bottom plate 1b of a bottomed cylindrical housing 1 with a two-layer structure and an upper opening. A heater 3 is attached, and the inside of the housing 1 is used as a water injection chamber 4.

[0009] A lid 5 is tightly fitted and fixed to the upper opening of the housing 1, and the lid 5 has an opening in the water injection chamber 4 and an injection port 6a in the center of the lid. An injection nozzle 6 positioned above 5 is fixedly fixed therethrough.

[0010] The injection nozzle 6 has a vent hole 7 whose inner diameter is large at the lower end and gradually becomes smaller toward the upper end, and the upper end surface of the vent hole 7 is formed by an inclined surface 8.
is formed. By forming the inner diameter of the vent hole 7 to be large at the bottom and small at the top, the injection pressure of the steam rising and passing through the vent hole 7 is increased. The steam that partially turns into water droplets upon contact with the water droplets is vigorously injected upward and diffused, and even if the water droplets w become attached to the upper end surface of the vent hole 7, they flow downward along the slope part 8. This prevents water droplets w from staying at the upper end opening of the vent hole 7.

[0011] On one side of the lid body 5, an inverted L-shaped water pipe 10, which has a conduit 9 opened at the upper surface position of the injection port 6a of the injection nozzle 6 and held in a horizontal state at the tip thereof, is penetrated and fixed. Moreover, the lower end edge of the water pipe 10 extends close to the inner bottom plate 1b.

[0012] An upright wall 11 is provided around the upper outer peripheral edge of the lid body 5, and a plurality of air injection holes 12 are bored in the upright wall 11 at appropriate intervals. A hanging wall 13 that can fit into the outer peripheral surface of the upright wall 11 and rotate in sliding contact is vertically provided on the outer peripheral edge of the upper plate 14, and a plurality of air holes are provided in the hanging wall 13 and communicated with the air injection holes 12. An adjustment cap 16 is formed by drilling the inflow adjustment hole 15, and by fitting the adjustment cap 16 to the upright wall 11, an air adjustment chamber 17 surrounded by the lid 5 and the adjustment cap 16 is formed. It is formed.

[0013] Also, the upper plate 1 of the adjustment cap 16
A guide cylinder 18 whose center line coincides with the injection nozzle 6 and whose lower surface is open to the air adjustment chamber 17 is installed in the center of the guide cylinder 4, and on the guide cylinder 18 is a guide cylinder 18 which can be attached to the nostril. , and a nostril inhaler 19 made of a flexible material such as rubber is placed in a shape that allows the atomized vapor to be inhaled. Note that 20 in the figure is a timer.

[0014] Next, the operation of the embodiment will be explained. Remove the adjustment cap 16 and lid 5 and open the water injection chamber 4.
Inject a predetermined amount of water into the lid body 5 and attach it to the housing 1.
Then, the adjusting cap 16 is fitted to the upright wall 11 of the lid 5, and preparation for inhalation is completed. Then, when the electric heater 3 is energized, the heat conductive plate 2
As the water is heated, the water in the water injection chamber 4 is gradually heated, and the boiling water turns into steam, passes through the ventilation hole 7 whose upper part has a small diameter, is pressurized, and is injected from the injection nozzle 6. Then, negative pressure is generated in the conduit 9 at the tip of the water pipe 10 inserted into the water in the water injection chamber 4, causing the heated hot water in the water injection chamber 4 to rise through the water pipe 10. The water droplets flow out from the conduit 9 in the form of water droplets, and the water droplets are mixed with the steam injected from the injection nozzle 6 to form an atomized state.
8 and then inhaled into the nostrils through the nostril inhaler 19.

[0015] During this time, some of the steam that has turned into water droplets due to contact with the outside air flows down along the slope part 8 of the upper end surface of the vent hole 7, so the water droplets w stay at the upper end opening of the vent hole 7. Never.

[0016] When the temperature of the mixture of water droplets and steam inhaled into the nostrils is high, the adjustment cap 16 is rotated so that the air inflow adjustment hole 15 of the adjustment cap 16 and the upright wall 11 of the lid 5 are connected. The air suction holes 12 are aligned to allow outside air to flow into the air conditioning chamber 17, and the outside air is mixed with the water droplet and steam mixture to lower the temperature. The temperature can be adjusted by rotating the adjustment cap 16 as appropriate to widen or narrow the air inflow opening between the air inflow adjustment hole 15 and the air suction hole 12.
This is done by adjusting the amount of air flowing into the air.

[0017]

[Effect of the invention] Since the present invention is as described above, steam is pressurized and injected from the vent holes formed in gradually smaller diameters as they move upward.
The steam, which has partially turned into water droplets when it comes into contact with the outside air, is vigorously injected upward and diffused, and even if it becomes water droplets and adheres to the upper end of the vent, it flows down along the slope and becomes water droplets. Water does not accumulate in the upper end opening of the vent, and therefore water droplets do not splash or make loud noises as in the conventional case.
