Description

Portable palm negative pressure cooling glove and control method thereof Technical Field The invention relates to the technical field of hand protection and temperature control, in particular to a portable palm negative pressure cooling glove and a control method thereof. Background Research shows that the increase of the core body temperature of a human body under a high-temperature environment or high-intensity exercise is a main cause of fatigue, cognitive decline and even heat shooting diseases. Two types of blood vessels exist on the surface of human skin, namely common capillaries and arteriovenous anastomosis branches (ArteriovenousAnastomoses, AVAs). AVAs are mainly distributed in hairless areas such as palms, soles, faces and the like, are direct channels for connecting arterioles and venules, and have extremely high blood flow regulating capacity. Stnford university study proves that cooling the AVA blood vessel in the palm region can cause the cooled blood to flow back to the heart and the core part of the human body rapidly, thereby realizing efficient core cooling. Experimental data show that the local negative pressure of 35-45/mmHg is applied to the whole hand, so that the AVA blood vessel can be obviously prevented from contracting blood vessel (Vasoconstriction) when being cooled, the blood circulation is maintained, and the core cooling efficiency is far higher than that of whole body spraying or ice compress when being matched with a heat dissipation surface of 18-22 ℃. The hand protection and cooling scheme in the current market mainly has the following three defects: the passive cooling is uncontrollable, and the existing cooling glove mostly adopts passive media such as ice bags, cooling gel and the like. Such means cooling duration is short, temperature fluctuates drastically with time, and the initial very low temperature is around 0 degrees celsius) easily triggers AVA vessel closure, but rather hinders heat exchange efficiency. The negative pressure auxiliary mechanism is lacking, and the common protective glove only has a basic protective function and does not have a negative pressure sealing structure. Under the condition of no negative pressure, the blood flow of the cooled part can be reduced due to the cold contraction of the blood vessel, so that the cooling effect is only remained on the surface of the skin and the core circulatory system cannot be reached. The monitoring and feedback are lacking, namely the prior art lacks a real-time pressure and temperature monitoring means, a user cannot accurately know the actual heat dissipation state of each region of the palm, so that the cooling parameters cannot be dynamically adjusted according to individual differences (such as the palm size and the basal body temperature), and the problems of frostbite risk or insufficient cooling exist. The sealing and flexibility conflict that the traditional sealing equipment is heavy, and the abrasion resistance and the operation flexibility required by industrial operation are difficult to be combined, so that the practicability of the traditional sealing equipment in high-strength operation scenes such as metallurgy, machining and the like is poor. In summary, the development of the palm cooling glove which can not only provide a stable negative pressure sealing environment, but also realize active temperature control, real-time monitoring and wear comfort has important practical significance for high-temperature operation protection and athletic performance improvement. Disclosure of Invention The present invention aims to solve the above-mentioned drawbacks. The technical scheme provided by the invention is that the portable palm negative pressure cooling glove and the control method thereof comprise the following steps: Glove body: the negative pressure sealing assembly is positioned on the back of the glove body and consists of a silica gel negative pressure air bag, a one-way air inlet valve and a one-way air release valve; The simplified refrigeration assembly is positioned on the glove main body and consists of a semiconductor refrigeration sheet and a heat radiation fin; The control power supply assembly is positioned on the palm surface of the glove body and consists of an LED display screen, a low-power consumption singlechip, a distributed air pressure temperature sensor and a button lithium battery; the miniature vacuum pump is arranged in the wrist area of the glove body; The miniature electromagnetic valve is respectively connected with the one-way air inlet valve and the one-way air outlet valve and is communicated with the miniature vacuum pump; wherein, miniature solenoid valve and miniature vacuum pump all are connected with low-power consumption monolithic electricity nature. Furthermore, the application also provides that the silica gel negative pressure air bag is arranged in the glove main body, and the one-way air inlet valve and the one-way air outlet valve are arra
