and user is extremely uncomfortable when wearing；In addition, when humidity is larger in environment, sunshade The contact position of cap and user's scalp is easy to produce sweat, and the degree of bearing dirty of sunbonnet is on the one hand caused to decline, and user needs It is often cleaned, the sweat on the other hand generated increases the airtightness of cap chamber further, on the temperature in cap chamber is quick It rises, user is easy to appear uncomfortable even heatstroke.The present invention provides a kind of sunshading cap with miniature electric fan of reducing temperature of heatstroke prevention； Common sunshading cap with miniature electric fan is usually that the fan being driven by motor is added on the brim of a hat, and the air outlet of fan is towards user's Face, although certain cooling effect can be played, on the one hand the fan being located on the brim of a hat can stop the sight of user, It makes troubles to user's trip, on the other hand can not cool down to the intracavitary portion of cap, basically form in the cap chamber of closed structure Temperature it is still higher, common sunshading cap with miniature electric fan is not strong to the cooling effect of user；The present invention and said fans formula hide One of the distinctive points of positive cap are, select the Pneumatic fan of blade-free and Pneumatic fan is located at the intracavitary portion of cap；There is no blade Pneumatic fan the hair of user will not be wound, thus can be set in cap chamber, in addition, compared to traditional wind Fan, vibration and noise is negligible when vaneless Pneumatic fan low-power operation, and when use does not have noise jamming, thus comfortable It spends higher；Pneumatic fan is located in cap chamber, is nearly at originally in the flowing gas driving cap chamber that Pneumatic fan generates static The gas of state quickly flows, and on the one hand the gas in the cap chamber in turbulence state can quickly reduce the temperature in cap chamber, real The effect of existing fast cooling, is on the other hand improved with the heat exchanger effectiveness on user head, the comfort level enhancing of user；This Outside, since cap chamber is not full-closed structure, the gas quickly flowed can flow out simultaneously from the gap on sunbonnet Yu user head It is contacted with the head of user being located at outside cap chamber, on the one hand the cryogenic gas persistently flowed out occurs heat with user head and hands over It changes, quickly reduces the head temperature of user, on the other hand the shape between the high-temperature gas in user head and external environment At cryogenic gas layer, the head of user is wrapped in cryogenic gas layer, thus can realize lasting reducing temperature of heatstroke prevention effect；The present invention It is with the two of the distinctive points of said fans formula sunbonnet, realizes the flowing gas of reducing temperature of heatstroke prevention effect by foot-propelled gas in the present invention Pump generates, and foot-propelled air pump is mounted at the heel of user, when user's walking, connecing between the heel and ground of user Touching be compartment, when user heel when being contacted with ground, foot-propelled air pump user weight squeeze under compress, foot The gas taken offence in pumping enters in appendix, and when the heel of user and surface separation, the pressure in foot-propelled air pump is less than outer Portion's air pressure, atmospheric pressure push gas to enter in foot-propelled air pump, and foot-propelled air pump expansion, the present invention is supplied using foot-propelled air pump, The energy of gas supply is another because without additional-energy feeding mechanism, on the one hand meeting Green Development theory from user Aspect reduces the overall weight of the sunshading cap with miniature electric fan of the reducing temperature of heatstroke prevention, and user carries extremely convenient when going on a journey；This hair In bright, when only on the foot of user installation foot take offence pump when, the supply of gas is discontinuous, due to the driving of fan Certain initial drive force is needed, the plenum system of discontinuous cannot achieve the continuous rotation of fan, thus in the head of user Portion can not form continuous cryogenic gas isolation layer, and the big heavy discount of reducing temperature of heatstroke prevention effect of sunbonnet is based on this, need additional one It is a to can be achieved the storage device of air that continuously supplies, in the present invention, it attached on appendix and store gas air bag, store gas air bag close to sunshade One end of cap is equipped with the pressure regulator valve of air-flow in cut-off appendix, is less than opening for pressure regulator valve when storing the gas pressure in gas air bag When pressure, pressure regulator valve closure, appendix without normal direction cap chamber supply, foot-propelled air pump provide accumulated gases store gas air bag in, when It stores the gas pressure in gas air bag and is greater than when opening pressure of pressure regulator valve, pressure regulator valve is opened, and the sunbonnet starts continuously to prevent Heat cooling work.

Preferably, pressure phase of the heel for opening user when pressure is walked with user of pressure regulator valve to foot-propelled air pump Deng.

When user's normal walking, heel squeeze feet is taken offence after pump compresses and is supplied to storage gas air bag, due to storing Gas air bag volume is larger, thus store that the air pressure in gas air bag is less than pressure regulator valve when foot-propelled air pump initially supplies opens pressure, when When storing the gas pressure and heel when user's normal walking consistent to the pressure of foot-propelled air pump in gas air bag, foot-propelled air pump makes It is difficult to compress when user's normal walking, at this point, pressure when user provides one higher than normal walking to foot-propelled air pump, by It is equal to the pressure of foot-propelled air pump in the heel for opening user when pressure is walked with user of pressure regulator valve, therefore pressure regulator valve exists It is opened under the action of pressure when this is higher than normal walking and the Pneumatic fan in cap chamber is supplied, stored in gas air bag Air pressure decline, but since pressure regulator valve at this time has already turned on, the closure of pressure regulator valve can only be carried out when gas flows and stops, and Gas air bag is stored to match with the user of continuous walking, thus appendix flow to the air-flow in cap chamber be it is continuous, so as to The head of user forms continuous cryogenic gas layer, and reducing temperature of heatstroke prevention effect is preferable.
