Description
Technical field
The present invention relates to a kind of headgear, be specifically related to a kind of cooling head cover.
Background technology
In daily life, after people are sick, fever is more common symptom.When body temperature rises time, health can feel very uncomfortable; Human body prolonged hay fever also can cause multiple other diseases.Therefore, treatment fever needs timely, effective.
Physical temperature-lowering measure conventional clinically at present comprises: cold wet compress, ice cube, ice pillow or ice cap, tepidarium, alcohol bath etc.But these traditional physical cooling methods exist many deficiencies, such as: adopt cold compress cooling often need change towel, inconvenient; Wayward by alcohol wipe method cooling alcohol concentration, and large area uses the ethanol Diazolidinyl Urea of high concentration, absorbs the moisture that epidermis is a large amount of.Therefore, we need the constantly new cooling material of research and development and cool-down method.
Phase-change material can change its phase in phase transformation range, absorbs, stores a large amount of heats with the form of latent heat, but, also do not find at present to use phase-change material in cooling head cover.
Summary of the invention
The object of the invention is to overcome the defect of above-mentioned prior art and provide a kind of based on phase-change material phase transformation cooling and headgear easy to use.
For achieving the above object, the technical scheme that the present invention takes is: a kind of cooling head cover, comprise headgear body, described headgear body is made up of phase change fiber or is provided with phase change fiber in described headgear body, described phase change fiber is made up of doughnut and the phase-change material be filled in doughnut, and the phase transition temperature of described phase-change material is 0 ~ 28 DEG C.
Phase-change material is undergoing phase transition in process and can store or release energy, and its temperature remains unchanged substantially.Select fusion temperature to be that the phase-change material of 0 ~ 28 DEG C is filled in doughnut, when wearing headgear, as long as phase-change material fusing, it just can absorbing and cooling temperature, ensures that the temperature of headgear is within the scope of 0 ~ 28 DEG C.
As the preferred implementation of cooling head cover of the present invention, the phase transition temperature of described phase-change material is 19 ~ 28 DEG C.When the fusion temperature of phase-change material is 19 ~ 28 DEG C, its phase transition temperature differs comparatively large with body temperature, when people wears cooling head cover, phase-change material easily undergoes phase transition; Moreover headgear temperature remains within the scope of 19 ~ 28 DEG C substantially in temperature-fall period, both effectively can absorb the unnecessary heat of human body, the series of negative physiological reaction such as can not cause that again the excessive cold expoure of skin, vasoconstriction and tissue are ached.
As the preferred implementation of cooling head cover of the present invention, the preparation method of described phase change fiber is: first phase-change material is heated to molten condition; Again one end of doughnut is immersed in phase-change material, the other end of doughnut is inserted one end of rubber tube, the connector of sealed hollow fiber and rubber tube; Finally the other end of rubber tube is connected with vacuum pump, phase-change material is sucked in doughnut.
As the preferred implementation of cooling head cover of the present invention, described phase-change material is the mixture of fatty acid ester or two or more fatty acid.The change of fatty acid phase-changing energy storage material its phase transition temperature, latent heat of phase change in long-term cold cycling process is all very little, good thermal stability; In addition, this kind of material also have nontoxic, corrosion-free, degree of supercooling is little, without advantages such as obvious phenomenon of phase separation, be a kind of phase-changing energy storage material of function admirable.
As the preferred implementation of cooling head cover of the present invention, described phase-change material is capric acid/myristic acid molecular alloy (capric acid/myristic acid molecular alloy refers to the molecular alloy that capric acid and myristic acid form).The fusion temperature of capric acid/myristic acid molecular alloy is 19.8 ~ 27.3 DEG C; When temperature is lower, capric acid/myristic acid molecular alloy is frozen into solid, and when temperature is higher than 19.8 DEG C, capric acid/myristic acid molecular alloy can melt heat absorption, thus plays the effect of cooling.In addition, capric acid/myristic acid molecular alloy has good heat stability, recycles its phase transition temperature, the heat of transformation repeatedly and still changes not quite.
As the preferred implementation of cooling head cover of the present invention, the preparation method of described capric acid/myristic acid molecular alloy is: take capric acid and myristic acid, put into glass container, uses rubber stopper seal glass container; Glass container first being put into 80 ~ 85 DEG C of calorstat heating 2.5 ~ 3h, then put in ultrasonic generator, is ultrasonic 95 ~ 100s under the condition of 45 ~ 48 DEG C at bath temperature; Take out glass container, make its natural cooling can obtain capric acid/myristic acid molecular alloy.
As the preferred implementation of cooling head cover of the present invention, the described capric acid/filling rate of myristic acid molecular alloy in doughnut is 80 ~ 85%.When capric acid/the filling rate of myristic acid molecular alloy in doughnut is 80 ~ 85%, can not ooze out after capric acid/myristic acid molecular alloy fusing, and the phase change fiber latent heat of phase change obtained thus is large.
As the preferred implementation of cooling head cover of the present invention, described phase-change material is butyl stearate.The fusing point of butyl stearate is 26 DEG C, and it is filled in after in doughnut, and fusing point remains unchanged.
As the more preferably embodiment of cooling head cover of the present invention, the filling rate of described butyl stearate in doughnut is 85% ~ 90%.In doughnut, the filling rate of butyl stearate is larger, and the latent heat of phase change of phase change fiber is larger; But when butyl stearate filling rate higher than 90% time, liquid stearic acid butyl ester can ooze out.When the filling rate of butyl stearate in doughnut is 85% ~ 90%, can ensure that liquid stearic acid butyl ester can not ooze out, the latent heat of phase change of phase change fiber can be made again large.
As the preferred implementation of cooling head cover of the present invention, described headgear body is the interlayer that double layer material is formed, and be also provided with at least one pocket in this headgear body, described pocket is built with described phase change fiber.Pocket has the effect of fixing phase change fiber.
As the more preferably embodiment of cooling head cover of the present invention, in described headgear body, be provided with a pocket; When wearing, described pocket is positioned at forehead position.
The using method of cooling head cover of the present invention and principle are: before use, need be put in low temperature environment by cooling head cover of the present invention or be placed in refrigerator, and the phase-change material in headgear is solidified.When wearing headgear, because human body temperature is higher, the phase-change material fusing heat absorption in phase change fiber, thus play cooling effect; In phase transition process, the temperature of phase-change material is substantially constant.
Beneficial effect of the present invention is: cooling head cover of the present invention is lowered the temperature based on phase-change material decalescence, its structure is simple, easy to use, not only can be used for the patient that has a fever, simultaneously also be applicable to the early stage patient needing the acute soft tissue injury of cold treatment, and muscle spasm caused by neuralgia, neuritis, neural excitation or muscle fatigue, high heat, heatstroke etc. can be treated.
