Technical Field

The invention relates to a household portable cold bag integrating semiconductors and evaporative refrigeration and a method, and belongs to the field of household human body scald treatment.

Background

In daily life, after a human body is scalded, the heat of the scald can form latent heat below the epidermis, and the latent heat is not easy to eliminate. The skin needs to be cooled continuously to eliminate latent heat penetrating into the skin, if the latent heat cannot be eliminated in time, the deep skin can be damaged due to overhigh temperature, wound infection can be caused, and scars are left. If scald appears in the family, the ice block is generally directly applied to the wound, however, in summer, the ice block is easy to melt after being used for a period of time, and the effect of continuously cooling the skin cannot be realized; and the ice block has large irritation to the skin, so that excessive contraction of skin blood vessels is easily caused by long-time ice compress, and the recovery of the scalded part of the skin is not facilitated. Therefore, there is a strong need for a device that can be directly contacted with the burned area, has a moderate temperature, and has a long cooling time to treat the burn. The portable cold bag is used for directly contacting the cold bag filled with cold water with a scald part of a human body, has proper temperature and can be fully contacted with the skin of the human body, and has better effect on cooling the scald skin of the human body.

However, the portable cold bag still has many problems at present, and can not really deal with the scalding situation. For example, CN201921899944.1 is a refrigeration bag, which uses chemical endothermic reaction for refrigeration, and has fast refrigeration time, but the cooling temperature is not well controlled, and the cooling time is short, and is restricted by the chemical reaction time, and thus, the refrigeration bag cannot be used continuously; for example, in the case of a refrigeration bag of cn201811131593.x, in consideration of the fact that the injured person cannot arrive at the hospital in time, a refrigeration bag capable of maintaining a low temperature for a long time is designed, the device refrigerates by endothermic reaction of the carbonyl amide particles and the water bags in the refrigeration bag, when rapid refrigeration is required, water in the water bags reacts with the carbonyl amide particles, however, when the device requires continuous refrigeration for a long time, water in the water bags reacts with the carbonyl amide particles at intervals, the refrigeration capacity is sacrificed on the basis of prolonging the time, and the refrigeration capacity of the device may be insufficient.

The invention designs a household portable cold bag integrating semiconductors and evaporative refrigeration, equipment integrates a water tank refrigeration system, a cold bag refrigeration system and a refrigerant circulating system, and the equipment can be carried about after the refrigerant circulating system is removed; the design of double cold bags is adopted, and the two cold bags form a one-use one-standby relationship, so that the continuous cooling time of the equipment is greatly prolonged; the semiconductor refrigeration mode and the evaporation refrigeration mode are alternately used, so that the cold bag is kept to have sufficient cold quantity.
