Detailed description of the invention

Traditional aerator mostly is curable product, its generally bulky, be difficult to carry, thus be not suitable for open air, long-time, low cost commonly used。It is directed to the situation that highlands visitor, staff etc. increase year by year, it is necessary to develop a kind of energy and be suitable for the new product of popular demand。

Deferring to technique scheme, as shown in Figures 1 to 5, a kind of highlands pressure self-balancing formula air intake system, including for compressed-air actuated supercharging air bag 4, and for supplying the feeder 2 of air to supercharging air bag 4；Air is supplied to supercharging air bag 4 by feeder 2, and supercharging air bag 4 is supplied to user after air is compressed supercharging。

Different from traditional all kinds of oxygen increasing equipments, the utility model proposes a kind of supercharging air bag 4, utilize the elastic reaction of supercharging air bag 4, pressurize to entering air therein, to reach to increase the purpose of unit space mole content of oxygen。

Highlands causes the reason of rarefaction of air to be that atmospheric pressure is low, pressure is low makes atmospheric density step-down, therefore if supplementing a part of pressure by the elasticity of supercharging air bag 4 wall, make the air pressure within supercharging air bag 4 can reach the degree of at least normal atmosphere, then supercharging air bag 4 inner air density becomes big, reaches or close to the human body breathing level in sea level altitude area。

According to Bernoulli equation it can be seen that flow velocity eminence air pressure is low, flow velocity lower air pressure is high, in this programme, feeder 2 agitates air to be supplied to supercharging air bag 4, makes the pressure in the middle of supercharging air bag 4 raise, more than the air pressure outside supercharging air bag 4, so that supercharging air bag 4 starts to expand。

When supercharging air bag 4 expand into after to a certain degree, as no longer continued inflation in supercharging air bag 4, then supercharging air bag 4 reaches temporary transient poised state。Now, gas pressure intensity in the middle of supercharging air bag 4, equal to supercharging air bag 4 outside atmosphere pressure with supercharging air bag 4 wall to supercharging air bag 4 internal gas pressure sum, namely the pressure in supercharging air bag 4 is greater than the atmospheric pressure outside supercharging air bag 4, difference is supercharging air bag 4 wall pressure to wherein gas, this part pressure makes the gas density within supercharging air bag 4 increase, and makes the gas in the middle of supercharging air bag 4 reach the level of suitable human body respiration。

After supercharging air bag 4 expands and balances, the pressure within supercharging air bag 4 is equal to outside atmospheric pressure with supercharging air bag 4 wall to gas pressure intensity sum in air bag。

According to equation of gaseous state: PV=nRT

P refers to pressure, and V refers to gas volume；N refers to that amount of substance, R are constants, and T refers to kelvin degree；

Again due to:M refers to that gaseous mass, M refer to the molal weight of gas, and therefore above formula can be changed into

PV=mRT/M

Then have: $P=\frac{mRT}{MV}=\mathrm{\ρ}\·\frac{RT}{M}$

ρ=m/V and gas density。

Therefore, same gas R/M is constant, and when gas temperature is constant, gas pressure intensity is directly proportional to gas density。

Therefore, this pressure charging system of this programme, available supercharging air bag 4, to air pressurized, makes oxygen content increase, then the air after pressurization is flowed to user, alleviates the hypoxic conditions of user with this。

Feeder 2 can have and selects space widely, and it needs air is provided certain speed, makes the air of entrance supercharging air bag 4 be enough to overcome the elasticity of supercharging air bag 4 wall to make it expand。Considering portable and light weight problem, whole feeder 2 should be not excessive。Such as feeder 2 can adopt small sized turbine blower fan, and turbofan is connected with electric supply installation 1, is connected with supercharging air bag 4 by air supply pipe 3；The benefit adopting turbofan is that, relative to the feeder 2 of other similar volumes, the wind speed of turbofan air outlet is fast, blast is big, it is easy to meet the instructions for use of supercharging air bag 4 in this programme。

About electric supply installation 1, chemical cell or other kinds of battery can be adopted, so that stable, the lasting energy can be provided for feeder 2。The performance of electric supply installation 1 directly determines the single use time of this system, therefore it is required that electric supply installation 1 can provide supply of electric power enduringly。It is contemplated that use the rechargeable battery of big electricity in this programme, can make this device when idle, the timely electric energy supplement of alternating current can be passed through, it is ensured that it can reach enough flying powers。

Carrying out in supercharging, suction process to air, the quality owing to sucking air is big relative to sucking air quality at ordinary times on plateau, therefore when environmental condition difference, it is contemplated that use defecator 5 that the impurity in air is filtered。Defecator 5 can have multiple choices, and the conventional all kinds of products for filtering air plankton are all it is contemplated that such as drainage screen, filter cotton 502 etc.。

Owing to defecator 5 needs timing to change cleaning, it is contemplated that the convenience of cost and replacing, it is proposed that a kind of defecator 5:

Defecator 5 includes filter tube 501, and filter tube 501 is internal is filled with filter cotton 502。

Filter tube 501 and filter cotton 502 can complete production use, and individually encapsulate。During use, a desirable new defecator 5, then connects in systems in the way of plug-in mounting。Concrete series position, it is possible to be between feeder 2 and supercharging air bag 4, or between supercharging air bag 4 and user, or above-mentioned two position is respectively provided with。

Further improvement as to technique scheme:

Supercharging air bag 4 supplies the air to user to supercharging air and by after heating device 6。

Owing to highlands temperature is relatively low, the supercool air of long-time incoming call can make human body large losses heat, does not more feel well for the people of hypoxic conditions。Consider, in air pressurized course of conveying, air is carried out a degree of heating for this this programme。

Heating device 6 can have multiple choices, and in this programme, heating device 6 includes the heating pipe 601 being embedded within snorkel 7, and the inwall of heating pipe 601 is provided with heater strip 602, or the inside of heating pipe 601 is laid with heating net。

The use of face shield 10 according to the actual preference of user, can be selected。One class face shield 10 is that venthole 9 is opened in part on face shield 10, and another kind of face shield 10 is to be opened in lower part。The effect of dividing plate 8 is, after making pressurization gas enter into face shield 10, remains in a relatively airtight space, in case pressurization gas communicates with surrounding air and reduces pressure。

When face shield 10 venthole 9 is opened in top timesharing, snorkel 7 is connected to the lower part of face shield 10。That is, after air enters face shield 10 lower part, incoming call from user mouth；Then utilize nasal cavity during user exhalation gas, gas is got rid of in the venthole 9 of part on face shield 10。

Similarly, when face shield 10 venthole 9 is opened in lower part, snorkel 7 is connected to the upper part of face shield 10。User now utilizes nose breathing gas, and oral area is passed through in aerofluxus, is got rid of from the venthole 9 of face shield 10 lower part by the gas of exhalation。

Thus achieve air-breathing, exhaling completely cuts off mutually, makes the gas of incoming call not contact with environmental gas, keeps the pressurized effect of gas。

In order to complete the air-breathing of user, exhalation process better:

The edge of face shield 10 is provided with sealing ring 11。

Sealing ring 11 can ensure the face shield 10 closely spiral-lock face at user, it is ensured that the seal of face shield 10, and sealing ring 11 has anti-compression functions simultaneously, makes patient wear impression more preferably。Face shield 10 can be worn on the face of patient by modes such as such as fixing band 12, ear mount。
