One humidity sensor 217 is for humidity value in the detecting one humidification box;

One humidity generator 218, function with humidification and dehumidifying, the principle of its humidification and dehumidification function, utilize airborne hydrone in a part sieve absorption humidification box 21, the water content of air in the humidification box 21 is reduced, reach the function of dehumidifying, after molecular sieve is filled hydrone, then by molecular sieve is heated, hydrone is discharged outside the humidification box 21; If during the moisture deficit of humidification box 21 interior air, then utilize the hydrone in molecular sieve adsorption humidification box 21 outer air, and, the water content of air in the humidification box 21 is increased, and reach the function of humidification by the molecular sieve heating is entered hydrone in the humidification box 21; Be with, in the process of this humidification and dehumidifying, there is no outside air and enter and preserve in the cabinet 10, it is hereby ensured that the preservation thing in preserving cabinet can not contact with outside air; In present embodiment, this humidity generator 218 is that the processor IC IC of EM78153 controls by a model mainly;

One humidification controller 219, be that the processor IC of 89C51 constitutes mainly by a model, it connects this drawing fan 213, admission air valve 215, humidity sensor 217 and humidity generator 218, and in have a humidification standard value and a high humility is kept program, when humidity value was not inconsistent this humidification standard value in this humidification box, this humidification controller 219 promptly started this humidity generator 218 and changes humidity.

This humidification buffer pocket 22 is communicated between this cabinet 10 and this humidification box 21, in it and preserve middle damp atmosphere; In present embodiment, be formed with four openings 221 on this humidification buffer pocket 22, these four openings 221 to gas access 211 and the gas vent 212 on a gas access 11 and gas vent 12 and the humidification box 21 wherein on should cabinet 10, are provided with in this humidification buffer pocket 22 again respectively:

One drawing fan 222, being located on this humidification buffer pocket 22 should be to wherein the opening 221 of a gas vent 12 is other on should cabinet 10;

One plenum fan 223, being located on this humidification buffer pocket 22 should be to wherein the opening 221 of a gas access 11 is other on should cabinet 10;

One admission air valve 224, being located on this humidification buffer pocket 22 should be on should cabinet 10 wherein on the opening 221 of a gas vent 12;

One valve 225 of supplying gas, being located on this humidification buffer pocket 22 should be on should cabinet 10 wherein on the opening 221 of a gas access 11;

One humidity sensor 226 is for humidity value in the detecting one humidification buffer pocket;

One buffering humidification controller 227, be that the processor IC of 89C51 constitutes mainly by a model, it connects this drawing fan 222, the plenum fan 214 of this humidification box 21, admission air valve 224, the supply gas valve 216 and the humidity sensor 226 of this humidification box 21, and in have one the buffering humidification standard value and one the buffering high humility keep program, wherein should cushion the humidification standard value less than this humidification standard value, this buffering high humility is kept program and is compared humidity value and this buffering humidification standard value in this humidification buffer pocket, when humidity value in this humidification buffer pocket is higher than this buffering humidification standard value, the air in this drawing fan 222 and this cabinet 10 of admission air valve 224 suctions is opened in these buffering humidification controller 227 i.e. controls, when humidity value in this humidification buffer pocket was lower than this buffering humidification standard value, then this buffering humidification controller 227 was promptly controlled the plenum fan 214 of opening this humidification box 21 and the valve 216 of supplying gas to obtain the air in this humidification box 21.

Cooperate above-mentioned explanation and please further consult shown in Figure 2ly, this high humility is kept program and is comprised the following steps:

Obtain humidity value 100 in the humidification box, the humidity sensor 217 of this humidification box 21 obtains humidity value in this humidification box certainly;

Whether humidity value is greater than humidification standard value 101 in the comparison humidification box;

Then begin humidification 102 if not, start this humidity generator 218 humidifications, otherwise then continue the following step;

Start this humidity generator dehumidifying 103, and open the drawing fan 213 of this humidification box 21 and this admission air valve 215 so that the air in this humidification buffer pocket 22 is sucked 104, because this buffering humidification standard value is less than this humidification standard value, therefore the air humidity in this humidification buffer pocket 22 must be less than the air humidity in this humidification box 21, so the air of obtaining and sneaking in this humidification buffer pocket 22 can quicken the effect on moisture extraction of this humidification box 21.

This desiccant cartridge 23 in present embodiment, is formed with a gas access 231 and a gas vent 232, and is provided with in this desiccant cartridge 23 for making the low humidity air on the side of this desiccant cartridge 23:
