Abstract
The utility model relates to a thermostatic shoe-pad with chemical heat medium, mainly composed of a soft sealed support shell (1), heat medium (2), and a heat preservation cover layer (3) sheathed on the support shell. The front palm part of the inner cavity shape of the sealed support shell (1) is provided with three to five rows of conical column tables, and the rear palm part is a quadrilateral net; the heat medium is the calcium chloride of hexahydrate and the strontium peroxide of supercooling-preventive agents. The front part of the shoe-pad is thin, the rear part is thick, and the gradient is formed. The shoe-pad is suitable for commercial production and is suitable for various environment temperature conditions, having comfortable wear.
Description
The utility model relates to a kind of Constant temp. shoe pad, especially utilizes material liquid---and absorption or release heat are regulated the Constant temp. shoe pad of temperature in the solid phase change process.
From medical angle, people foot skin temperature is lower than about 9 ° of body temperature, and foot suffers from cold and easily catches a cold.Investigation shows that it is 8:1 with the flu incidence of disease of wearing cotton-padded shoes that single footwear are worn at severe winter in the north.According to surveying and determination, wear common leather shoes in the room that heating installation or stove are housed and stood on concrete floor 1 hour, the skin temperature of pin will descend about 1 ℃.If only wear socks, just can descend more than 2 ℃ in 10 minutes, according to this physiological characteristic,, be very healthy for pin provides 27-30 ℃ of preference temperature.People are in order to create this environment, multiple winter protection or cooling measure have been taked, Chinese patent CN2051837 discloses the cool pad of a kind of phase change cold-storage, go into lauryl alcohol or hexadecane cold-storage material with storage in the soft can, its shortcoming is that thickness is big, the scope of application is little, and heat insulation effect is not obvious under cold environment.CN2121872U discloses in the soft can chamber that is made of plastics and has made bar shaped arranged side by side, cover the last layer lining on the shell, interior dress 40-70% U-Ramin MC saturated solution medium can make the mat temperature remain on about 29 ℃, its shortcoming is easily to cross cold hardening, makes pad and uses comfortable inadequately.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, provides a kind of applicability good, can prevent the shoe-pad of easy supercooling hardening.
The technical scheme that realizes above-mentioned purpose is: support shell by soft material such as the sealing of plastic injection-moulded one-tenth, there is 3-5 row circular cone pylon at cavity shape half sole position, the rear palma position be network of quadrilaterals every, cover last layer sealing thermal-insulation coat on soft can, sealing is supported in the outer shell cavity and is filled chemical heat media six hydration calcium chloride CaCl
26H
2O adds supercooling and prevents the anhydrous strontium peroxide SrO of agent
2, six hydration calcium chloride and strontium peroxide weight proportion are 10:0.1-0.5.
Shell is supported in soft sealing has a protruding platform that matches with human body arch of the foot concave shape in arch portion, and the circular cone pylon bus of preceding metacarpus and the angle at the end are 121 °, and pin rear palma position is a quadrilateral mesh, and a tetragonal angle is 75-80 °.This soft sealing supports that shell front is partly thin, the back is partly thick, and a gradient is arranged, before and after it size than 5/12 for good.
The utlity model has following advantage: 1, soft sealing support shell adopts one-shot forming to make, the suitable large-scale industrial production that carries out, 2, applicability is good, can in high temperature or cold environment, use, 3, because of there being supercooling to prevent agent, so be difficult for hardening, 4, molded dimension is suitable for the effect of human foot's proper motion pressure and tensile force.
Accompanying drawing is an embodiment of the present utility model.
Fig. 1 is the utility model Constant temp. shoe pad section of structure.
Fig. 2 is the utility model Constant temp. shoe pad vertical view.
In conjunction with the accompanying drawings the utility model Constant temp. shoe pad is being further described down.
Constant temp. shoe pad is by soft waterproof footwear advance expenditure support shell 1 in the accompanying drawing, chemical heat media 2 and sealing thermal-insulation coat 3 are formed, soft waterproof footwear advance expenditure support shell, by plastic injection-moulded shaping, there are the uniform frustum of 3-5 row, high about 5mm in its cavity shape half sole position, the angle at the frustum bus and the end is 121 °, the rear palma position is a quadrilateral mesh, and a tetragonal diagonal angle is 75-80 ℃, and there is a boss that matches with the arch of the foot spill at centre of the palm place.Be covered with a full envelope overcoat 3 on the soft waterproof footwear advance expenditure support shell 1, adopt good polypropylene or the plastics nonwoven hot synthetic type of gas barrier property, thermal medium 2 adopts six hydration calcium chloride and anhydrous strontium peroxide, and the weight ratio of six hydration calcium chloride and strontium peroxide is 10:0.1-0.5.The practice is that chemical heat media is mixed, and is heated to 40-50 ℃ of hot melt and separates, and is injected into behind the mixing in the soft waterproof footwear advance expenditure support outer shell cavity to seal.When the saturated blending agent in the shoe-pad is cooled to 27 ℃, begin to have a little crystallization, temperature begins to stablize, and prolongs in time, and its crystallization increases.When 10 ℃ of room temperatures, do not add the insulation measure, but constant temperature 77 minutes, and to reduce to 18 ℃ of times be 2 hours to heat medium temperature in the pad.When ambient temperature was higher, it absorbed heat again, can remain on the temperature that 27-30 ℃ of human foot suits.
Before need heating up with this chemical heat media Constant temp. shoe pad, if with heater as a frame electrothermal transducer heating fusion, insert in the footwear and get final product, need solar heat protection, as long as its mat cooling is solidified, insert again that footwear are interior to get final product, can use repeatedly.Material is inexpensive, be easy to get, and is pollution-free.Therefore, available correlation technique system seat cushion, mattress are having broad application prospect aspect the civilian insulation.
