Description
Technical field
The present invention relates to a kind of satchel with anti-tail gas function, specifically a kind of functional carry-on satchel with pernicious gas devices such as filtering motor exhausts.
Background technology
Nearly all working clan and the great majority race that goes window-shopping all takes on and carries on the arm, takes on the back of the body or hand carries multi-form satchel, and walking or walk by bike is being filled the air on the pernicious gas streets such as motor exhaust.Growing with each passing day of city fuel combustion vehicle, be that the city pernicious gas of main component is day by day dense with motor exhaust, streets and lanes are shrouded in the tail gas filled the air.Air pollution is serious, and mouth mask becomes trip necessary article.Day by day serious in the face of this and cannot alleviate air pollution speedup, disadvantaged group uniquely can as can only be wear a secondary mouth mask, to filtering noxious gas, be seen everywhere in city the passerby masked one's nose and mouth with a cloth.Streets and lanes, shoulder is carried on the arm, take on the helpless area of people that the back of the body or hand carry satchel of all kinds on mouth mask miscellaneous.But common mouth mask can only filtering part pellet, in fact of no avail to the pernicious gas taking tail gas as main component, still can be subject to air-polluting infringement many times people.Such as by bike or walking trip, on the road filling the air motor exhaust, breathing problem becomes more outstanding.On the one hand, be because the PM2.5 of air and the expansion of following middle fine particle pollutant component, on the other hand, be that current mouth mask is passive type filtration, do not possess the filter capacity of middle fine particle.Because be that passive type filters, if improve fine particle ability in its filtration by the measure of such as encrypting, thickening fabric, expiratory dyspnea will be caused simultaneously.Like this, originally simple and easy to do mouth mask also becomes the equipment that Trouble after trouble comes up.Therefore, the problem of fine particle in high efficiency filter to be solved on the one hand, solve again on the other hand and breathe unimpeded problem.This just needs to research and develop a kind of active filtering formula high-performance mouth mask, it can filter in fine particle, can not expiratory dyspnea be caused again.But this equipment may cause to a certain extent and carry inconvenient, makes a set of support annex often for this reason specially.Need research and development one can realize active filtering formula mouth-muffle function for this reason, the equipment to this function body support function can be realized again.
Summary of the invention
For realizing by active filtering formula mouth-muffle function and to this function body support function integration, the present invention proposes a kind of satchel with anti-tail gas function.This equipment comprises satchel body, gas-electric portion, silica gel matter flexible material escape pipe and carries band on the arm.In the lower left corner of satchel body, gas-electric portion is installed; In the left side of satchel body, draw the escape pipe in gas-electric portion; Escape pipe extends to along the left side of satchel body and carries band on the arm, and carrying in band the top walked to carrying band on the arm on the arm, and at top from carrying extraction in band on the arm; The end of giving vent to anger of escape pipe, is connected with mouth mask portion.
The technical solution adopted for the present invention to solve the technical problems is:
In the lower left corner of satchel body, gas-electric portion is installed; In the left side of satchel body, draw the escape pipe in gas-electric portion; Escape pipe extends to along the left side of satchel body and carries band on the arm, and carrying in band the top walked to carrying band on the arm on the arm, and at top from carrying extraction in band on the arm; The end of giving vent to anger of escape pipe, is connected with mouth mask portion.
Gas-electric portion is the functive being configured with out air filter, high-voltage tube, circuit box, air inlet, air intake filter, air storage bag, baroceptor, inflating pump, safety valve and low-voltage tube, and this functive dressing is in fiberglass rigidity package shell.Go out the left side that air filter is assemblied in functive in package shell, upwards, inlet end is downward in outlet side; The inlet end of the gas outlet and escape pipe that go out air filter is connected, and through with escape pipe 3; The left bottom of functive in package shell, the outlet side of the air inlet and high-voltage tube that go out air filter is connected through, and is connected through by high-voltage tube with the interface of air storage bag; Circuit box is assemblied in the bottom meta in package shell by rubber mass bail, be lined with latex crash roll at the interval of the bottom surface of circuit box and package shell bottom surface; Battery chamber's buckle closure of circuit box and shift bar are given prominence to, through package shell and satchel body.Air inlet is assemblied in the position, bottom right of functive, and prosopyle end is outside, through package shell and satchel body; The rear port of air inlet is connected with the air inlet of air intake filter; Baroceptor is arranged between the air storage bag of high-voltage tube and inflating pump; Inflating pump is assemblied in the bottom right side in package shell by rubber mass bail, is lined with latex crash roll at the interval of the bottom surface of inflating pump and package shell bottom surface; The air inlet of inflating pump is connected with the gas outlet of low-voltage tube.Safety valve is connected across between high-voltage tube and low-voltage tube, and its high-pressure mouth is assemblied between the baroceptor of high-voltage tube and inflating pump gas outlet, through with high-voltage tube; Its low pressure port is assemblied between the inflating pump air inlet of low-voltage tube and air filter gas outlet, through with low-voltage tube.The inlet end of high-voltage tube is connected with the gas outlet of inflating pump; The air inlet of low-voltage tube is connected with the gas outlet of air intake filter.High-voltage tube and the low-voltage tube shock insulation flexible pipe all for being made up of silica gel matter flexible material.
The present invention makes the trip satchel commonly used become a kind of heath-function equipment, and also working clan is with the right of eupnea.It can not only filtering pellet, again can the various pernicious gas of filtering.Due to flap valve interstage valve structure, negative pressure during air-breathing makes flap valve close Window for ventilation, and linkage opens flap, thus makes wearer suck the pure air that five layers are filtered through two ends; During expiration, flap valve opens Window for ventilation, and linkage closes flap, thus the smooth and easy discharge of the waste gas that wearer is breathed out.Adopt five layers, two ends filtration system, can filter the little fine particle to 0.3 micron and reach 99.9%, powerful purification function is had no place to hide by PM2.5.Wherein HEPA material can not only remove various virus, bacterium and fine particulates, more effectively can remove the organic chemistry gas such as 91% formaldehyde, 95% toluene.Meanwhile, be suitable for utilize material all have ready-made standardized product, and structure simple, with low cost, be easy to batch production.
