Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes oxygen in the air supplied from a breathing cylinder of a diver according to the diving depth to a chemical heating element in a heating element storage bag attached to a diving suit. The present invention relates to a diper warming device which uses the heat of reaction to keep the diper warm, and is further equipped with a safety device that can deal with abnormal situations at any time.

Conventionally, there are electric heating methods, hot water heating methods supplied from land or a mother ship, heating methods using radioactive heat sources, and heating methods using chemical agents to keep the dipper warm during work. All methods using radioactive heat sources require large-scale equipment at the land base or mother ship, and are fraught with many problems in terms of safety management.In addition, in the case of chemical agents, they combine with water and generate heat. Both methods had some drawbacks, such as the reaction caused by water injection proceeding rapidly and temperature control being difficult.

Development of a heat-retaining device that eliminates these drawbacks, is easy to operate, warms the entire body of the diaper, allows the temperature to be adjusted on its own, is as simple as possible in structure, and can be worn with peace of mind without causing the diaper to feel uneasy. was strongly requested. The present invention has been made in view of the above circumstances, and utilizes the air in a breathing cylinder and supplies it to a chemical heating element housed inside a diving suit to generate heat, thereby producing a heat-retaining effect. , safety measures such as having a function to immediately stop the supply of air in the event of a sudden rise in temperature, and taking emergency measures to completely prevent accidents such as burns by injecting water from outside in the event of abnormal heat generation. The object of the present invention is to provide a heat-retaining device equipped with a heat-retaining device. The present invention will be described below based on examples with reference to the drawings.
FIG. 1 is an explanatory diagram showing a diaper heat retention device according to the present invention. Reference numeral 1 denotes a breathing cylinder that the diver carries with him when diving, and an automatic air supply regulator 2 is attached to the head of the cylinder.

This regulator supplies air with a pressure corresponding to the diving depth to the mouthpiece 3, and also supplies air of the same pressure to the conduit 4.
It is now possible to supply The regulator is also provided with an emergency cock 5, which has the function of immediately cutting off the air supply when an exothermic reaction, which will be described later, progresses excessively. 6 is a cylinder residual air pressure gauge.

Next, the air supply valve 7 is composed of a slide type air valve 8 and a push button type air supply valve 9.

As shown in detail in FIG. 2, the air valve 8 has an outer cylinder 8a that is slidable left and right, and three rollers 8b, 8c, and 8d.
The inner cylinder 8e is provided with small hole groups 8f and 8g through which air flowing in the direction of the arrow can freely pass. The figure shows the open state, but conversely, the outer cylinder 8
When a is slid, small hole groups 8f and 8g are rolled 8
b and 8c, so that air flow in the direction of the arrow is stopped. In addition, as shown in FIG. 3, the push-button air supply valve 9 can be pressed continuously from the top of the figure to eliminate contact between the rolling 9a and the valve wall 9b, allowing the heating element to flow through the small hole group 9c that is electrically connected to the heating element storage bag. It has a structure that allows air to flow into the storage bag 11. However, the structure of the air supply valve consisting of the air valve and the push-button air supply valve 9 is not limited to this example, and other models may not be adopted as long as they provide similar effects. isn't it. Returning to FIG. 1 again, a known chemical heating element 12 made of, for example, a special iron sulfide is sealed in a heating element storage bag 11 that communicates with a push-button air supply valve 9 through a wetsuit 10. .

This chemical heating element generates heat only when oxygen is supplied.

Therefore, Diaper's own body is cold. When it becomes necessary to keep warm, slide the air valve in the opening direction, and
By continuing to press the push-button air supply valve 9, air can be introduced into the chemical heating element to achieve its purpose.
The heating element storage bag filled with chemical heating elements is waterproof and moisture-proof. The wetsuit is usually attached to the inner wall of the wetsuit or worn inside the wetsuit as an innersuit. Next, the product of the present invention has several safety measures in place.

That is, in addition to the emergency cock 5 provided to instantly stop the flow of air from the cylinder to the air supply valve via the conduit, there is also an emergency water injection valve/exhaust valve with a push button 13 shown in FIG. 14 are provided. As shown in the detailed view of FIG. 4, this valve has a push button 13 protruding into the water, which is fitted into the sponge rubber 10 of a wet suit, and by pushing down the push button, the contact between the rolling 14a and the valve wall 14b is released. The heating element storage bag 11 is inserted through the gap that occurs.
Water can be injected or exhausted from the inlet 14d through a group of small holes 14c through which it passes. When water is injected through the emergency water inlet/exhaust valve 14 with a push button, the temperature rise due to heat generation inside the heating element storage bag becomes excessive and cannot be suppressed by simply stopping the introduction of air, that is, there is a risk of causing burns to the dipper. In such cases, the chemical heating element can be rapidly cooled by forcing water to flow into the heating element storage bag by pressing down on the push button 13. Furthermore, if for some reason the amount of reaction gas becomes large and the internal pressure of the heating element storage bag becomes high, the exothermic reaction will suddenly slow down and a sufficient heat retention effect may not be achieved. This phenomenon can be predicted from the abnormal expansion of the heating element storage bag. However, if the reaction gas is discharged by the amount of the increased internal pressure, fresh air is introduced again and the exothermic reaction progresses smoothly.The reason why a single valve is used for water injection and exhaust is that the internal pressure of the diving suit is This is because the pressure is normally adjusted to be 7 kgIcf1 or more higher than the water pressure, and while the internal pressure of the heating element storage bag is higher than the internal pressure of the diving suit, if the push button is continued to be pressed, the reaction gas will be discharged into the water. Further, when the internal pressure of the heating element storage bag returns to normal, the state returns to a state where water can be poured by pressing the push button.

Since the present invention is based on the above configuration, the drawbacks of each heating method of electric heating, hot water, and radiation heat source are improved,
In addition, the conventional chemical agent heating method uses a chemical agent that generates heat when water is added, making it extremely difficult to control the temperature and almost never putting it into practical use.In contrast, the present invention makes temperature control extremely easy. It has an important feature in that it uses a chemical agent that generates heat from the air, has a simple structure, is easy to install, and uses a part of the air in a breathing cylinder. It can be sent into the storage bag of a chemical heating element attached to the diving suit and reacted with the heating element to keep the dipper warm at any time, and it can also be used in an emergency if the temperature rises too much. If the air supply can be immediately cut off using the stopcock, and there is a risk of abnormal overheating,
It is equipped with a safety device that allows for instantaneous water injection, making it extremely useful in practice compared to conventional heat-retaining devices.
