Description

[Detailed Description of the Invention] The present invention relates to a compact, light, safe, and clean rapid heating cylinder for liquids, etc.

As a heating cylinder for liquids, etc., there is a device proposed in Utility Application No. 48-41336, but this heating cylinder produces a flame from the tip of the heating cylinder, and also produces a considerable amount of sparks and smoke made of solid powder. There were drawbacks.

The generation of flames, sparks, and smoke can be caused by the use of portable cups for warming sake, coffee, etc.
Not suitable for heating tea, milk, etc.

Therefore, the inventor of the present invention aimed to provide a rapid heating cylinder that not only does not emit flames, but also emit almost no sparks or smoke.
Through extensive research and ingenuity in the structure of the heating agent and heating cylinder, they were able to discover a distant relative of the purpose.

That is, in the present invention, a small hole is provided at the tip of a cylindrical container made of a metal that is a good thermal conductor, and 30 to 30% of trilead tetroxide powder is contained in the container.
A heating agent consisting of 40 parts by weight, 2 to 5 parts by weight of aluminum powder, 20 to 40 parts by weight of silicon iron powder, and 20 to 30 parts by weight of cupric oxide powder (however, the total amount is 100 parts by weight) was added to the upper part of the container. This invention relates to a cylinder for rapidly heating liquid, etc., characterized in that the cylinder is filled with a space left in the opening, and a string-like ignition agent connected to the heating agent is exposed above the small hole.

The present invention will be explained in detail below.

The heating agent used in the present invention is a self-combustible one that contains a reducing agent and an oxidizing agent.Of course, theoretically, the reducing agent and the oxidizing agent should be contained in an equivalent relationship, but one Even if it is in excess, it does not mean that it will not work as a heating agent.
A certain range is allowed for the quantitative ratio.

The reason for using a combination of aluminum powder and silico-iron powder as a ring agent is because the reaction would be too violent if aluminum powder alone was used, and the reaction would be too slow and the temperature raising effect would be insufficient if silico-iron powder alone was used. .

The reason for using the oxidizing agent in combination with trilead tetroxide powder and cupric oxide powder is also that the reaction is too vigorous with trilead tetroxide powder alone, and the reaction is too strong with cupric oxide powder alone. This is because the temperature increase effect is insufficient because it is too slow.

The present invention is characterized in that the self-combustible heating agent is constructed by using appropriate amounts of aluminum powder and iron silicon as reducing agents, and using appropriate amounts of trilead tetroxide and cupric oxide powder as oxidizing agents. However, if the trilead tetroxide powder is less than 30 parts by weight and the aluminum powder is less than 2 parts by weight, the reaction will be too slow and the generation of heat to raise the temperature will be insufficient.
If the amount of aluminum powder is more than 5 parts by weight, the reaction will be too vigorous, resulting in generation of flames and sparks, which is undesirable from a practical standpoint.

Examples of suitable compositions include 37 parts by weight of trilead tetroxide powder, 3 parts by weight of aluminum powder, 35 parts by weight of silicon iron powder, and 25 parts by weight of cupric oxide powder.

As the metal with good thermal conductivity in the present invention, for example, aluminum, alumite, etc. are preferably used.

As a string-like igniter, for example, a cotton string with 55 to 50% lead tetroxide
A material impregnated with 75 parts by weight and 45 to 25 parts by weight of silicon iron is used.

The string-like igniter is connected to the heating agent, and passes through the space to emerge from the small hole at the tip of the container.

If you ignite the end of this string with a matchstick or lighter, the combustion will move and transmit the flame to the heating agent.

The shape and size of the cylindrical container can be appropriately determined depending on its intended use.

The most commonly used shape is cylindrical.

The tip of the container may be squeezed into a conical shape like the tip of a sharpened pencil, or it may be left as is.

Further, at this time, the cylindrical tip may be caulked into a star shape having six protrusions to make the tip thinner.

The accompanying drawings show a sectional view of an embodiment of the present invention.

In the figure, 1 is an aluminum tube container, 2 is a heating agent filling layer, 3 is a string-like ignition agent, 4 is an upper space, 5 is a small hole at the tip of the container, and 6 is a string-like ignition agent tip.

In one embodiment of the present invention, an aluminum heating cylinder having an outer diameter of 14 mm and a height of 14 Q mm and having the shape shown in the drawings is filled with 37 parts by weight of trilead tetroxide powder, 3 parts by weight of aluminum powder, and silicon-iron powder. 35 parts by weight and 2 cupric oxide powder
Filled with 20 g of heating agent consisting of 5 parts by weight, 1
When I put it in a pot filled with 80 cc (1 cup) of water and ignited the string-like igniter, it burned for about 20 seconds.
The water temperature rose from 6°C to 50°C.

At that time, flames and sparks were emitted from the tip of the heating tube, but only a very small amount of smoke was seen rising.

The heating cylinder of the present invention uses a heating agent with a specific composition that appropriately maintains the intensity of the reaction, has a space at the top, and has a container opening at the tip. By having small holes, it is possible to rapidly heat liquids, etc. without generating flames, sparks, or smoke, and it meets the requirements of small size, convenience, cleanliness, and safety. It is completely satisfactory and is extremely suitable for heating sake, coffee, tea, milk, amazake, miso soup, soup, etc. outdoors and in vehicles. If it is sold with one heating cylinder attached, it is considered to be a very good product.

Of course, the shape, size, and uses of the heating cylinder of the present invention are not limited to those described above, but are broader in scope.
