Background

The high temperature not only affects the intelligence of people, but also affects the emotion and the psychology of people, people are easy to make mistakes when taking the head and the head with fever, and people have good judgment when taking the cold and quiet shape. If a simple and effective method is available, the brain of the human can be maintained to work at the optimal temperature and high efficiency, such as examination and study, or the human can be concentrated when the human is engaged in high-risk work, such as driving a car and working aloft. It will help people to improve efficiency and reduce risk. In hot days, people are easy to have a fidgety mood and study without feeling down.

Researchers at the public health academy of Harvard university study the relationship between air temperature and cognition, and find that the cognitive function of young people living in a residence without an air conditioner and with higher temperature is obviously affected, the reaction speed is reduced by 13%, and the processing capacity of events is reduced by about 10%. The result shows that the working efficiency is the best at 22 ℃, the work delay is high and low, the working efficiency is only 91.1 percent of the maximum value when the room temperature reaches 30 ℃, the examination on the hot day is not good easily, and the probability of passing the examination is 10.9 percent lower for high school students in New York city examined on the 32 ℃ weather than that of the examination on the 22 ℃ weather.

The cooling hat in the prior art generally adopts methods of fan blowing, semiconductor refrigeration, water evaporation cooling and the like, wherein the fan blowing needs electricity and can generate noise, the semiconductor refrigeration also needs electricity, and the water evaporation cooling is a simple and easy method and has the defect that people can feel uncomfortable like sweating. Another disadvantage of the prior art is that it is not possible to maintain a constant temperature.

Disclosure of Invention

The technical problem is as follows: why people easily make mistakes when the weather is hot. So that people can keep the best intelligence state at high temperature. The present invention provides an explanation and provides a solution.

The basic rule of regulating body temperature in a homeothermic animal is that a large amount of blood is transported to epidermal capillaries which are easy to dissipate heat when hot, and the blood volume obtained from the brain and internal organs is reduced, which is the main reason that human reactions are slowed down when the temperature is high. The invention provides a phase-change energy-storage cooling hair ring, a cooling head ring and a cap, which can keep the head cool and quiet under dry and cool conditions; when the color-changing agent fails, the color-changing agent can change color, can be automatically regenerated after being taken down and placed at room temperature or soaked in cold water or placed in a refrigerator, can be repeatedly used, and can effectively improve intelligence quotient after being used for a long time.

The technical scheme is as follows:

a phase-change energy-storage cooling hair ring, a cooling head ring and a cap comprise 11 of a heat-insulating sleeve, 12 of a hose, 13 of a heat-conducting pipe, 14 of a cooling pipe and 15 of a solid-liquid phase-change material; the solid-liquid phase change material (15) is arranged in the hose (12), the heat conduction pipe (13) is also arranged in the hose, the heat insulation sleeve (11) is sleeved outside the hose (12), and two ends of the cooling pipe (14) are connected with two ends of the hose (12); the cooling hair ring is sleeved on the head, the cooling pipe (14) is attached to the forehead, the forehead temperature is higher than the phase change temperature of the solid-liquid phase change material (15), the solid-liquid phase change material (15) in the hose absorbs heat and is gradually liquefied, the temperature can be kept constant during solid-liquid two phases, and when the cooling hair ring is taken down in a cold place, the solid-liquid phase change material (15) in the hose emits heat to be solidified and regenerated due to the fact that the environment temperature is lower than the phase change temperature, and therefore the cooling hair ring can be repeatedly used. The solid-liquid phase change material is generally hydrated salt and macromolecular grease, such as one or more of CaCl 2.6H2O, MgCl 2.6H2O, Na2B4O 7.10H2O, NaCl, fatty acid, paraffin, palm oil, coconut oil and the like, and is liquefied and endothermic when the temperature is higher than the phase transition temperature and solidified and exothermic when the temperature is lower than the phase transition temperature; the solid-liquid phase change material can also be other organic matters or any combination of organic matters and inorganic matters. Because the cooling hair ring, the cooling head ring and the cooling cap are used for cooling the head when the temperature is higher than 22 ℃, and the normal body temperature of the head is about 37 ℃, the solid-liquid phase change temperature is between 16 and 30 ℃, preferably between 20 and 26 ℃. Select the phase transition temperature between 20~26 ℃, the head can not feel too cold, and cerebral blood vessel can not consequently obviously contract yet, can satisfy basically and wear cooling brain daytime when the day is hot, keeps the brain dry and cool, gets night and puts down and is less than the solid-liquid phase transition temperature in the cold water when being lower than, the release heat that can be convenient again, the difference in temperature of make full use of daytime and night, the convenient liquid-solid phase transition of carrying on is regenerated. The worst result is to put it in a refrigerator for regeneration.

Further, the phase change material is selected from hydrated salt, which does not become hard like simple substance during phase change, is easy to break off or is uncomfortable to wear and inconvenient to carry.

Furthermore, the heat-insulating sleeve is thin on the side contacting with the skin, thick or poor in heat conductivity on the other side, so that heat is easily conducted on the side close to the skin, and the side not contacting with the skin is thick or poor in heat conductivity, so that heat insulation is facilitated.

Furthermore, the temperature sensing color changing powder near the phase change temperature is doped into the phase change material, so that the failure and regeneration can be conveniently displayed.

Furthermore, the elastic band or the adhesive band is arranged on the upper surface of the heat-insulating sleeve, so that the tightness and size of the wear can be conveniently adjusted.

Furthermore, the hose is divided into a plurality of mutually independent spaces, and other independent spaces can still be normally used after the hose is partially damaged.

Furthermore, when the hose is made of materials with good touch feeling of human bodies such as silica gel, the heat insulation sleeve can be omitted, and the hose can still be normally used.

Further, the cooling pipe is made of metal, such as aluminum or aluminum alloy, magnesium or magnesium alloy.

Further, the heat conductive pipe is a metal such as aluminum or an aluminum alloy, magnesium or a magnesium alloy.

Further, the hose is transparent, such as a transparent silicone hose.
