Problems solved by technology
The heating method of this method is to induce crystallization by physical impact. In more detail, it should be placed in objects that can generate vibrations, or attached to the surface, so the manufacturing process is complicated, and the heating time lasts for a short time. Uneven, difficult to use for a long time outside the disadvantages

Embodiment 5
[0032] In Example 5, injecting more than 5% of the volume of air into the warming bag, the hydration reaction of the aqueous solution of sodium acetate from the air accelerates, and as a result, the formation of solid crystals is accelerated. The warming bag maintains heat above 35℃ for less than 4 hours.

The invention discloses a thermal bag and thermal device, which consists of sodium acetate aqueous solution and air, wherein the bag can induce the oversaturation sodium acetate crystal for a long time, which utilizes the radiation power in the sodium acetate crystal course to keep thermal; the color change material is added in the thermal bag, which can displays the present temperature condition timely.
Description
【Technical Field】 [0001] The present invention relates to a thermal bag, in particular to a thermal bag containing sodium acetate aqueous solution and air that can keep warm for a long time. The present invention also relates to a warming device using the above warming bag. 【Background technique】 [0002] So far, many inventions that can generate heat have been developed for use outdoors in cold weather. Korean Utility Model Registration No. 20-0217323, No. 20-0305190, and No. 20-0395466 describe heat-insulating seat cushions that are heated by electricity after a hot plate or hot wire is placed inside. Although this kind of thermal insulation seat cushion has the advantage of continuously generating heat, it can only be used in places with electricity. [0003] In order to solve this problem, we developed a thermal bag that does not require the chemical principle of power supply. Especially the supersaturated sodium acetate solution is unstable and will easily crystallize and re...
