Detailed description of the invention
Fig. 1 is the present invention looks up structural representation of automobile fresh air oxygenation air cleaning roof window of the present invention；
Fig. 2 is the side structure schematic view of automobile fresh air oxygenation air cleaning roof window of the present invention.
Specific embodiment
With reference to the accompanying drawings and detailed description, automobile fresh air oxygenation air cleaning roof window of the invention is made into one
Step is described in detail.
Automobile fresh air oxygenation air cleaning roof window of the invention, it is outer with air inlet 1 outside roof including being mounted on
Shell 2 and inner housing 4 be mounted in roof and with air outlet 3, as seen from the figure, the bottom of inner housing is arranged in air outlet
Portion is at least provided with one or more air inlets in vehicle traveling direction on outer housing 2, naturally it is also possible in the left and right of outer housing
Two sides are also equipped with one or more air inlets, that is to say, that multiple air inlets can be provided in the surrounding of outer housing, this
Invention is not limited it, is mounted on intake stack 7 outside each air inlet, it is preferable that intake stack be it is downward opening into
Windbend pipe when production, opens up 6-10 centimetres of circular hole of diameter on outer housing 2, and be with diameter it is possible thereby to play the effect of rain-proof
The L-type section aluminum pipe of 6-10CM is equipped with silk screen in nozzle, is directly accessed this circular hole, plays and introduces the outer air of vehicle, air inlet, oxygenation work
Direction with the L-type aluminum pipe that, this diameter is 6-10CM is adjustable, mainly according to when installing and using, the traffic direction of vehicle and
Air quantity when use changes, and is mounted with installation frame 5 in inner housing 4, is provided in installation frame 5 for purifying to air
Treatment facilities, outer housing 2 and inner housing 4 are coupled and form air flow lumen body between the periphery of installation frame 5
6, specifically, to constitute a fresh air by outer housing, inner housing and treatment facilities this covering device net by installing on the car body
Change roof window, bottom side can be provided with escape knob and grip switches, escaping function be played, as a safety roof
Window uses, and safe escape roof window has been the product popularized on car, does not repeat herein, and treatment facilities includes being pacified by installation frame
The filtering material of dress and the evaporation fan being arranged in inside installation frame, evaporation fan have two-way air-out passage, and two-way goes out
Two arranged side by side air outlets 3 of wind channel face, evaporation fan face air outlet simultaneously can will be after filtering material filter
Air introduce and evaporation fan and directly purified air be discharged into car body by air outlet 3, air follows realization vehicle outside
Ring purification；In addition, be provided with the ventilation opening of face filtering material on inner housing 4, the intracorporal air of vehicle can by ventilation opening into
Enter into air flow lumen body 6 and then carry out purified treatment, circulating purification in in-vehicle air is achieved in, in conjunction with above-mentioned handle
The outer air of vehicle introduces interior purification (realizing air outer circulation) structure, air circulating purification (air outer circulation) and car outside vehicle
In air circulation (interior circulation) purification process, evaporation fan is placed in installation frame dexterously will be outside purified fresh air and vehicle
Wind is kept apart, and is designed by the structure, ventilation (ventilation volume up to 800 cubic metres per hour) and can will be introduced outside vehicle
Atmosphere purified, removal PM2.5PM10 is equal to pernicious gas, moreover it is possible to which ventilation introduces oxygen to interior oxygenation, simultaneously
Interior formaldehyde, toluene dimethylbenzene TVOC are equal to nocuousness, are drawn into fresh air purifying skylight by the ventilation opening of inner casing body side surface
It is purified in purification device.
Further, it is provided with outlet housing outside air outlet, is mounted on outlet housing aobvious between two air outlets
Display screen, the negative oxygen ion generator being provided in described inner housing 4 at air outlet 2, filtering material include except formaldehyde, remove
Toluene removes TVOC resolution process cellular material, HEPA filtering material, so that fresh air purifying roof window can introduce the outer oxygen of vehicle
Gas, ventilation, and harmful substance in air can be removed: such as PM2.5, formaldehyde, toluene, dimethylbenzene, TVOC harmful object
Equipment purifies in-vehicle air.
Still further, being additionally provided with double high-pressure electrostatic electric fields in described installation frame 5, better air is thus played
Clean-up effect.
In addition, evaporation fan is mounted in the middle part of the cavity of installation frame, wherein mistake for the installation for the treatment of facilities
Filter material material is installed by installation frame, and described installation frame includes the cavity that left side plate and front and back side plate surround, can
To offer notch in the left and right side plates of installation frame, and it is formed with outside left side plate the filtering for grafting side
The slot of material, certain slot correspond to ventilation opening, cover one piece of top filtration again after filtering material insertion slot in side is interior
Then material is provided with for the seal cover board at the top of disposing at the top of installation frame, filtering material is inserted by slot respectively
It connects and installation is sealed by seal cover board, when installation, first side filtering material is inserted into the slot outside the side plate of two sides,
The top filtration material for covering one piece big after in side filtering material insertion slot again, then recycles seal cover board to big top
Portion's filtering material is fixed, and this completes the integral installations for the treatment of facilities.
Automobile fresh air oxygenation air cleaning roof window through the invention, air and atmosphere outside vehicle, is entered the wind by roof
Into entering in fresh air oxygenation air cleaning unit, the hollow out metal covering for passing through two left side plates of metal frame (filters side mouth
Material) and by the cellular filter filtration of material at top, while interior air is also from the hollow out metal covering of two sides of metal frame
Side filtering material and by top cellular filter filtration of material, enters in air cleaning unit after purification, and fresh air is the bottom of from
The fan outlet in portion, is blown out in compartment, is isolated specifically, the outer atmosphere of vehicle enters in skylight by air inlet by outer
Shell and inner housing are coupled in the air flow lumen body formed between the periphery of installation frame afterwards, pass through 2 side hollow out aluminium
After the filtering material filtering in frame face (left side plate), just enter in treatment facilities, purified fresh air passes through evaporation fan
Air outlet is blown out in compartment, and purified fresh air and vehicle exogenous wind are kept apart, and not only effectively realizes interior circulation, moreover it is possible to introduce vehicle
Outer air is purified, and makes interior circulation in conjunction with outer circulation, by verifying, outlet air fresh air volume and ventilation volume >=800m3/h。
By carrying out interior pellet PM.5 to using automobile fresh air oxygenation air cleaning roof window of the invention
The sampling Detection of removal effect and fresh-air ventilation amount, testing result are as follows:
