Description

The utility model relates to an air cushion which can maintain a constant temperature state and is composed of at least one outer layer element, an intermediate air cushion layer and an inner lining, which can not only be heat-insulated, cold-insulated, and kept warm, but also have the ability to withstand pressure and cushioning.

Ordinary liners, such as shoe linings used at low temperatures, clothing lining insulation panels (such as fireproof clothing) or heat-retaining containers, have many disadvantages despite their advantages in breathability or warmth. An overview is as follows:

1. Inner lining of shoes: Shoes (such as snow boots, etc.) worn in low-temperature and cold environments: the inner layer of the boot body is made of water-absorbent or breathable fabric, which is directly combined with the outer leather upper. Because the capillary pores of the leather upper can also breathe freely, the body temperature of the feet inside the shoe can be dissipated, and the cold air and moisture from the outside can also penetrate through the capillary pores, causing damp inside the shoe and frostbite on the feet, making the wearer feel uncomfortable. Comfortable, and in a low temperature environment, it is very easy to frostbite the feet and affect human health.

Another example is shoes that are suitable for high temperature and safety protection environments (such as deserts, tropical jungles or high temperature places). Because people exercise a lot, their feet sweat a lot, and this kind of shoes have poor air permeability, resulting in damp inside the shoes, making the People feel very uncomfortable.

2. Clothes lining: Although the materials used in various clothes are different, they can achieve different degrees of heat preservation effect, but all linings made of woven fabrics have air-permeable gaps (braiding thread gaps), which make the heat preservation effect extremely limited, so the heat preservation effect is affected; if encountering a high temperature environment, because this material has heat conduction effect, and at the same time it is easy to stick to the human body, making people feel uncomfortable; and general clothes do not have waterproof function, easy to Absorb sweat and make clothes damp (whether it is wet from rain or sweat), especially after being blown by cold wind outdoors, it is easy to catch a cold.

3. If it is used as a raincoat, it is more because it is made of airtight colloidal material, and it is always in direct contact with human skin (especially in summer) when wearing it, so that perspiration is not easy to evaporate, and poor air permeability makes people feel uncomfortable.

4. At present, the fire-fighting clothing widely used by firefighters only coats the outer layer of the clothing with a layer of fire-resistant material similar to tin foil. Fireproof, but the effect of heat insulation and ventilation is not very good.

5. At present, the shoulder pads, elbow pads, and knee pads used by athletes to protect their limbs are completely made of leather or foam. Although they have good wear resistance, they have poor shock absorption and elastic buffering of external forces. , once the position of this utensil protection is bumped, still can produce great pain, and wears some hardness, affects the flexibility and comfort of people's activities, and moreover, ventilation perspiration effect is also poor.

6. Seriously ill patients who have been bedridden for a long time and cannot turn over and move by themselves, because the back is attached to the mattress for a long time without ventilation, and sweating makes the back wet, which causes back skin ulcers and other diseases. The reason is that the back and the mattress are ventilated The air permeability is not good, so that the muscles are oppressed for a long time without any activity to relieve, resulting in blood flow and paralysis, which ultimately affects the activation of cells in the human body.

The purpose of this utility model is to provide an air cushion that can maintain a constant temperature, which can isolate the internal and external temperatures, communicate and conduct each other, and can achieve the effect of heat insulation (warm preservation) and cold insulation (cold preservation), and can withstand the external temperature. Impact pressure, with the effect of shock absorption, cushioning and comfort.

It provides a flow space for the gas inside, so as to generate a cushioning elastic force, so as to ensure that the airbag will not burst and be damaged when it is subjected to a momentary impact. Moisture in the cushioning part; the inner lining is a sheet-like body with an appropriate thickness, which can be selected from breathable or water-absorbent cloth, or fiber paper, or fiber wool and other materials according to the use object and occasion. It is pasted on the inner side of the middle air cushion layer; after the three elements are superimposed on each other, the air cushion layer is interposed between the outer element and the inner lining.

The middle air cushion layer can be made up of at least three or more sheets of sheet-shaped colloidal materials, wherein each layer of air cushions can be molded and equipped with protruding airbags, which are arranged in opposite or staggered positions to increase the cushioning of the utility model capacity and flexibility. The above-mentioned airbags can be of different sizes, diameters, heights or volumes, and can be arranged regularly or irregularly, so as to adapt to different pressures of different parts and achieve a balanced effect of increasing cushioning force and elasticity. Grooves can be set on the periphery of the cushioning part on the airbag to relieve the accumulated water and increase the ventilation effect.

In addition, the cushioning portion on each airbag of the above-mentioned air cushion layer can also be arranged at the peripheral position of the top surface of the airbag.
