Abstract
The utility model discloses a kind of reusable heat bag, comprise and in sealing bag, sealing bag, supersaturated solution is housed and metal excites sheet, metal excites sheet to be coated with thermal insulation layer, its advantage is that metal excites sheet to be coated with thermal insulation layer, in the time of microwave heating, temperature can be higher under microwave heating for the sheet that excites of metal material, the setting of thermal insulation layer can avoid the metal of heating to excite sheet to contact with the direct of sealing bag, prevent that sealing bag is because being subject to heat ageing, shrinking or breaking, increase the number of times of reusing of heating bag.
Description
Technical field
This utility model relates to a kind of liquid pyrotoxin, relates in particular to a kind of reusable heat bag.
Background technology
Heat bag is a kind of articles for use for naturopathy and daily health caring, and it can generate heat under without other external heat source conditions.China Patent No. is that the utility model patent of 201320186885.X discloses a kind of heat bag, it comprises sealing bag, sodium acetate supersaturation acid solution and metal are housed in sealing bag and excite sheet, this sodium acetate supersaturation acid solution excites crystallization heating under the exciting of sheet at metal, this crystalline solid is cooled to room temperature gradually after several hours at persistent fever; In the time that needs reuse, heat bag need to be immersed in hot water, crystalline solid can again recover the original liquid condition that arrives after absorption heat, and this heat bag can repeatedly use.Also can utilize microwave to heat heat bag, the crystalline solid heating of microwave penetration sealing bag to its inside, crystalline solid converts solution state to after having absorbed most heats of microwave, although metal excites sheet in body supersaturated solution, but temperature still can be higher under the thermal source such as microwave or hot water heating condition for the sheet that excites of metal material, higher temperature excite sheet to contact with sealing bag after, can cause aging, the contraction of sealing bag, even likely can cause the perforation of sealing bag or break, this can reduce the reusable number of times of heat bag.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of in the time that the thermal source such as microwave or hot water heat, thereby avoids sealing bag effectively to increase the reusable heat bag of access times because metal excites breakage that sheet excess Temperature causes.
This utility model solves the problems of the technologies described above adopted technical scheme: a kind of reusable heat bag, and comprise and in sealing bag, described sealing bag, supersaturated solution is housed and metal excites sheet, described metal excites sheet to be coated with thermal insulation layer.
Described thermal insulation layer is electrophoretic paint layer or plastic layer or nylon layer of cloth.Metal excites sheet coated upper enamelled coating after electrophoresis process is processed, and is applicable to large-scale production, and production cost is lower, and effect of heat insulation is relatively good, is not easy to come off, and service life is long.
Plastic layer is PVC layer.Production cost is lower, and effect of heat insulation is relatively good, is not easy to come off, and service life is long.
Sealing bag is made up of high resiliency PVC material.The degree of polymerization of high resiliency PVC material is 2500 left and right, and its fusing point is 170 degree～180 degree, under hot water or microwave heating condition, is not easy to be softened.Cold-resistant degree, in subzero 25 degree left and right, is applicable to cold district.
Described metal excites sheet to be made up of stainless steel material, and described metal excites being shaped as of sheet square or circular.Stubborn moving metal excites sheet can induce supersaturated solution crystallization, and the metal that rustless steel is made excites sheet to have better toughness, after being broken, more easily returns to original shape, and square metal excites sheet more easily to touch in the sealing bag that contains solution.
It is 0.5mm～5mm that described metal excites the thickness of sheet, and the thickness of described thermal insulation layer is 0.1mm～2mm.The metal of this thickness excites the flexibility of sheet better, and the thermal insulation layer of this thickness can be avoided metal to excite between sheet and sealing bag contacting, and can not affect metal again and excite the flexibility of sheet simultaneously.
PVC layer is made up of high resiliency PVC material.
Supersaturated solution is sodium acetate supersaturated solution.Sodium acetate supersaturated solution has better crystal property and heat absorption capacity, and can reuse repeatedly.
It is 0.8mm or 2mm or 3.5mm that described metal excites the thickness of sheet, and the thickness of described thermal insulation layer is 0.5mm or 1 mm or 2mm.The metal of this thickness excites the flexibility of sheet better, and the thermal insulation layer of this thickness can be avoided metal to excite between sheet and sealing bag contacting, and can not affect metal again and excite the flexibility of sheet simultaneously.
Sealing bag is made up of transparent material.It is transparent that sealing bag is, and sodium acetate supersaturated solution is not being also transparent color before crystallization, and user can find metal to excite sheet easily.
Compared with prior art, the utility model has the advantages that metal excites sheet to be coated with thermal insulation layer, in the time that the thermal source such as microwave or hot water heats, temperature can be higher under the heating of the thermal source such as microwave or hot water for the sheet that excites of metal material, the setting of thermal insulation layer can avoid the metal of heating to excite sheet to contact with the direct of sealing bag, prevent that sealing bag from, because being subject to heat ageing, shrinking or breaking, effectively increasing the number of times of reusing of heating bag.
