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 that has pernicious gas device such as filtering motor exhaust.
Background technology
Nearly all working clan and the great majority families that go window-shopping all take on and carry, take on the back of the body on the arm or hand is carried multi-form satchel, and walking or walk is by bike being filled the air on the pernicious gas street such as motor exhaust.Growing with each passing day of city fuel combustion vehicle is that the city pernicious gas of main component is dense day by day with the motor exhaust, and streets and lanes are shrouded in the tail gas that fills the air.Air pollution is serious, and mouth mask becomes the trip necessary article.In the face of this serious day by day and can't alleviate air pollution speedup, disadvantaged group are unique, and what can be used as can only be to wear a secondary mouth mask, in the hope of filtering noxious gas, and the passerby who is seen everywhere in the city and masks one's nose and mouth with a cloth.The back of the body is carried, is takeed in streets and lanes, shoulder on the arm or hand is carried mouth mask miscellaneous on the helpless area of people of satchel of all kinds.Yet common mouth mask can only filtering part pellet, to being that the pernicious gas of main component is of no avail in fact with tail gas, still can be subjected to the air-polluting infringement people many times.For example by bike or walking trip, filling the air on the road of motor exhaust, it is more outstanding that breathing problem becomes.On the one hand, be because the expansion of the PM2.5 of atmosphere and following middle fine particle pollutant component on the other hand, is that present mouth mask is the passive type filtration, do not possess the filter capacity of middle fine particle.Because be that passive type filters, if by improve fine particle ability in its filtration such as the measure of encrypting, thickening fabric, will cause expiratory dyspnea simultaneously.Like this, originally, simple and easy to do mouth mask had also become the equipment that Trouble after trouble comes up.Therefore, to solve the problem of fine particle in the high efficiency filter on the one hand, solve the unimpeded problem of breathing on the other hand again.This just needs a kind of active filtering type high-performance mouth mask of research and development, and fine particle during it can filter can not cause expiratory dyspnea again.Yet this equipment may cause to a certain extent and carry inconveniently, often makes a cover support annex specially for this reason.Need to research and develop for this reason and a kind ofly can realize initiatively filter-type respirator function, can realize the equipment to this function body support function again.
Summary of the invention
For realizing that with active filter-type respirator 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 of gas-electric portion; Escape pipe extends to along the left side of satchel body and carries band on the arm, and walks in carrying band on the arm to the top of carrying band on the arm, and draws from carrying on the arm in the band at the top; 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 of gas-electric portion; Escape pipe extends to along the left side of satchel body and carries band on the arm, and walks in carrying band on the arm to the top of carrying band on the arm, and draws from carrying on the arm in the band at the top; The end of giving vent to anger of escape pipe is connected with mouth mask portion.
Gas-electric portion is the functive that disposes 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 the package shell, the outlet side makes progress, and inlet end is downward; The gas outlet that goes out air filter is connected with the inlet end of escape pipe, and connects with escape pipe 3; The left bottom of functive in the package shell, the air inlet that goes out air filter is connected perforation with the outlet side of high-voltage tube, and is connected perforation by high-voltage tube with the interface of air storage bag; Circuit box is assemblied in bottom meta in the package shell by the rubber mass bail, between the bottom surface of circuit box and package shell bottom surface every being lined with the latex crash roll; Battery chamber's buckle closure of circuit box and shift bar are outstanding, pass package shell and satchel body.Air inlet is assemblied in the position, bottom right of functive, and the prosopyle end is outside, passes package shell and satchel body; The rear port of air inlet is connected with the air inlet of air intake filter; Baroceptor is installed between the air storage bag and inflating pump of high-voltage tube; Inflating pump is assemblied in right side bottom in the package shell by the rubber mass bail, between the bottom surface of inflating pump and package shell bottom surface every being lined with the latex crash roll; 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 the low-voltage tube, and its high-pressure mouth is assemblied between the baroceptor and inflating pump gas outlet of high-voltage tube, connects with high-voltage tube; Its low pressure port is assemblied between the inflating pump air inlet and air filter gas outlet of low-voltage tube, connects 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 low-voltage tube be the shock insulation flexible pipe for being made by silica gel matter flexible material all.
The present invention makes trip satchel commonly used become a kind of health care equipment, and also the working clan is with the right of eupnea.It can not only the filtering pellet, again can the various pernicious gases of filtering.Because flap valve interstage valve structure, the negative pressure when air-breathing makes flap valve close Window for ventilation, and linkage is opened flap, thereby makes the wearer suck the pure air of five layers of filtration through two ends; Flap valve is opened Window for ventilation during expiration, and linkage is closed flap, thus the smooth and easy discharge of the waste gas that the wearer is breathed out.Adopt the five layers of filtration system in two ends, can filter little fine particle to 0.3 micron and reach 99.9%, powerful purification function is had no place to hide by PM2.5.Wherein the HEPA material can not only be removed various viruses, bacterium and fine particulates, more can effectively remove organic chemistry gases such as 91% formaldehyde, 95% toluene.Simultaneously, the material that is suitable for utilizing all has ready-made standardized product, and simple in structure, with low cost, be easy to produce in batches.
