Abstract
The utility model discloses a kind of automotive air filter and escape device, comprises the free air diffuser that wind-proof cap, outer shelter, body inner casings and filtering installation housing form, and the inflow point of described free air diffuser arranges air-inlet grille and air-in screen; Described outer shelter is fixed on bracing frame, and support frame as described above and automobile case are coupling; Fixed filter unit on support frame as described above; Described filtering installation comprises filtering installation housing, arranges motor, motor shaft arranges wind impeller in described filtering installation housing, arranges air-in screen, PM2.5 filter screen, active carbon filter screen and protective grille below wind impeller; The utility model has the advantages that: because air is in interior circulation, therefore, the noxious gases such as outside vehicle exhaust cannot enter interior, and by PM2.5 filter screen and activated-carbon filter net filtration, the noxious gas in compartment is progressively filtered; In addition, owing to being inner loop, interior temperature is not affected; In addition, be provided with escape handle, in emergency circumstances, the safety of personnel can be ensured.
Description
Technical field
The utility model relates to technical field of air purification, is a kind of air filtration and escape device specifically.
Background technology
Passenger vehicle is in transportation, and especially air conditioned passenger car, because number is more, air does not exchange with outside, therefore, the non-constant of air quality, for solving this technical problem, existing passenger vehicle often arranges scavenger fan at the top of automobile, the object of scavenger fan is only ventilate, and gas in car and outside gasses are exchanged, the method has the defect of two aspects, one is the temperature that the a/c system destroyed in car brings, and cannot ensure the proper temperature in car; Two is because present air is poor, especially travels a fairly large number of place at vehicle, and the tail gas that automobile is discharged, containing a large amount of noxious gas, changes to automotive interior by the method, still can not solve air quality problems.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of automotive air filter and escape device, and concrete technical scheme is as follows:
A kind of automotive air filter and escape device, comprise the free air diffuser that wind-proof cap, outer shelter, body inner casings and filtering installation housing form, the inflow point of described free air diffuser arranges air-inlet grille and air-in screen; Described outer shelter is fixed on bracing frame, and support frame as described above and automobile case are coupling; Fixed filter unit on support frame as described above; Described filtering installation comprises filtering installation housing, arranges motor, motor shaft arranges wind impeller in described filtering installation housing, arranges air-in screen, PM2.5 filter screen, active carbon filter screen and protective grille below wind impeller; Other one end of support frame as described above arranges outer handle and Internal handle, and bracing frame is fixed on automobile case by described Internal handle and outer handle.
Described Internal handle is arranged in emergent protective cover, and described emergent protective cover arranges switch knob protecting cover.
Described air-in screen, PM2.5 filter screen, active carbon filter screen from top to bottom, are arranged in order.
Described air-in screen is two-layer, and the aperture of ground floor is greater than the aperture of the second layer from top to bottom.
The utility model has the advantages that: because air is in interior circulation, therefore, the noxious gases such as outside vehicle exhaust cannot enter interior, and by PM2.5 filter screen and activated-carbon filter net filtration, the noxious gas in compartment is progressively filtered; In addition, owing to being inner loop, interior temperature is not affected; Again, be provided with escape handle, in emergency circumstances, the safety of personnel can be ensured.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The utility model is illustrated below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprises the free air diffuser that wind-proof cap 9, outer shelter 10, body inner casings 8 and filtering installation housing 20 form, and the inflow point of described free air diffuser arranges air-inlet grille 6 and air-in screen 7; Described outer shelter 10 is fixed on bracing frame 21, and support frame as described above 21 and automobile case 16 are coupling; Fixed filter unit on support frame as described above 21; Described filtering installation comprises filtering installation housing 20, in described filtering installation housing 20, electric machine support 13 is set, fixed electrical machinery 14 on described electric machine support 13, motor shaft is arranged wind impeller 15, arranging air-in screen 1, PM2.5 filter screen 2, active carbon filter screen 3 and protective grille 5 below wind impeller 15, is activated carbon bodies 4 below described active carbon filter screen 3; Other one end of support frame as described above 21 arranges outer handle 18 and Internal handle 17, and bracing frame 21 is fixed on automobile case 16 by described Internal handle 17 and outer handle 18.
For ensureing optimum efficiency, air-in screen, PM2.5 filter screen, active carbon filter screen from top to bottom, are arranged in order, and described air-in screen is two-layer, and the aperture of ground floor filter screen is greater than the aperture of second layer filter screen from top to bottom.The benefit of such setting is: first, with first group of filter screen, the larger dust in air in car is filtered, the PM2.5 filter screen that the Particle Blocking diameter preventing diameter larger is less and active carbon filter screen, make another two groups of filtering nets below can play maximum utility and improve service life.
Secondly, second layer air-in screen, after ground floor filter screen filtration, filters harmful and less micronic dust further further, ensures follow-up PM2.5 filtering net and activated carbon filtration effect.
Again, objectionable impurities PM2.5 in air is filtered clean with PM2.5 filtering net.Because the molecule in air is through above three layer filtration, be substantially blocked in active carbon filter screen before, therefore, during activated-carbon filter net filtration, avoid the skin that molecule is wrapped in active carbon, active carbon absorbs more thorough to the pernicious gas in air, improve adsorption efficiency; Objectionable impurities can not only be removed further, and the peculiar smell in energy deaeration, be in car, keep clean clean air circulation.
For preventing the maloperation of passenger, described Internal handle 17 is arranged in emergent protective cover 11, and described emergent protective cover 11 arranges switch knob protecting cover 12.
Described outer shelter 10 is connected with wind-proof cap 9, and described outer shelter 10 relatively automobile case is protruding, can prevent rainwater from flowing backwards like this.
In figure, the direction of arrow indication is gas flow direction.
