Portable electronic cooling instrument

Abstract

The invention discloses a portable electronic cooling instrument. The portable electronic cooling instrument has the advantages that the cold conduction medium of the electronic cooling instrument uses hydrogel materials as the cold conduction materials; the hydrogel materials are quite soft, can fit different forehead shapes and are high in comfortableness and capable of achieving even cold conduction; compared with the prior art, the portable electronic cooling instrument uses the hydrogel materials to transfer a cold source to the skin of a human body; under the premise of even cold conduction, due to the fact that the heat conductivity of the hydrogel materials is larger than that of water in the prior art, that is to say, the hydrogel materials are fast in cold conduction, the cold consumption of the hydrogel materials is low, the cold conduction efficiency of the hydrogel materials is high, the power consumption is low under the same cooling requirements, and the purposes of lowering power consumption, saving energy and increasing the endurance of the portable electronic cooling instrument can be achieved; in addition, the cold conduction medium is simple in manufacturing process and long in service life.

Description

technical field [0001] The invention relates to the technical field of household and medical auxiliary instruments, in particular to a portable electronic cooling instrument. Background technique [0002] Fever in children is a common disease. When the body temperature is below 39°C, it is recommended to use physical cooling, especially when the body temperature exceeds 39°C, because the child's body is not yet fully developed, it will cause the greatest damage to the brain, and even easily lead to brain dysfunction. Symptoms such as unconsciousness and general convulsions are called febrile convulsions in medicine. If the number of convulsions is not taken care of in time, it will cause damage to brain cells and affect mental development. Traditional physical cooling methods such as cooling stickers, ice packs, wet towels, alcohol wipes, etc. have various defects. Therefore, the market needs a safe, effective, portable, and portable cooling device. [0003] In the prior a...

AI Technical Summary

Problems solved by technology

[0009] The above-mentioned technical solution has the following defects: the cold source is transferred to the skin of the human body through the above-mentioned cold-conducting medium, and the cold source (i.e. cold loss) lost during the transfer process is more, so the cold transfer efficiency is low, wherein, cold transfer efficiency=cold utilization Capacity / total cooling production=(total cooling production-cooling loss) / total cooling production

Due to the low cold transfer efficiency, under the same cooling demand (that is, the same cooling utilization), the required power consumption (that is, the total cooling capacity) is large, and the battery life is weak, so a special battery or power adapter is required. The battery life is 1-2h (input power 9V-2A), if you want to increase the battery life, the volume of the battery will double and increase the carrying burden
