Blower fan 7 is for gas circulation in case, make gas inlet and outlet air treatment system in case, by controller, control strategy is taked to blower fan 7, when making that in case, gas reaches certain humidity, blower fan 7 starts, and dehumidifies in case, and when gas humidity drops to claimed range, blower fan 7 stops, and makes case humidity reach dynamic equilibrium.
Air treatment system described in the present embodiment is divided into two parts:
1, the outer gas of case enters in case
Keep the closedown of airtight housing lid 8, open accessibke porosity cover plate 10, close inner via hole 3, open channel I, under the factor such as ambient temperature, height above sea level causes change of atmospheric pressure, case outer air is through filter 4 and dehumidifier 6, make air purity, organic pollutant and humidity up to standard, also enter in case by fresh air inlet simultaneously, packing case inner and outer air pressure can be made equal.
This design can direct treatment box outer air, and make its cleanliness factor and humidity meet the demands in laggard cartonning, such casing need not be designed to bearing structure, and manufacturing cost can be made greatly to reduce.
2, gas circulation in case
Keep the closedown of airtight housing lid 8, close accessibke porosity cover plate 10, open inner via hole 3, open channel II, opens blower fan 7, makes gas in case continue to enter treatment chamber from inner via hole 3 and flow through circulation passage and flow out from fresh air inlet, by continuous circulation, cleaning gas degree in case is met the demands; By humidity sensor detection case humidity, thus control blower fan 7 automatic start-stop by controller, blower fan 7 starts higher than during top limit of humidity in humidity, make air by dehumidifier 6, reduce humidity, stop in limited time lower than under humidity, cut off air to contact with dehumidifier 6, avoid case humidity too low.
The invention header is ventilated outward and case Inner eycle is integrated, and both can meet pressure inside and outside case equal, makes it to possess freely " breathing " function, can meet again case inner air-cleaning dehumidification function.
Between airtight housing lid 8 and airtight housing 1, be also provided with sealing ring 5, thus ensure the sealing of whole treatment chamber.
The foregoing is only the preferred embodiment of the invention; not in order to limit the invention; within all spirit in the invention and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in the invention.
