For achieving the above object, the utility model provides following technical scheme: a kind of dehumidifying medical cupboard, comprise cabinet and be arranged on some shelfs of cabinet inside, the bottom of described cabinet is also provided with exhaust chamber, the top of described cabinet is also provided with air admission hole, also be provided with blower fan and hothouse between described exhaust chamber and air admission hole, the air outlet direction of described blower fan is just arranged hothouse, and described hothouse inside is provided with drier.
Further, described cabinet inside is also provided with humidity measuring circuit and dehumidification module, and described humidity measuring circuit is for detecting cabinet interior humidity, when cabinet humidity is greater than preset value, send drive singal, when described dehumidification module receives drive singal, control described blower fan work.
Further, described humidity measuring circuit comprises humidity sensor, detects humidity and exports a humidity sampled voltage; Humidity base modules, provides humidity reference voltage; Humidity comparison module, is coupled to humidity base modules and humidity sensor, when humidity sampled voltage is greater than humidity reference voltage, exports humidity comparison signal; Executive Module, when receiving humidity comparison signal, exports dehumidifying signal.
Further, described dehumidification module comprises multivibrator and fan drive circuit, and described multivibrator is controlled by drive singal and sends Sasser, and described fan drive circuit receives Sasser, for driving blower fan work.
Further, described humidity base modules comprises one for regulating the adjustable resistance of humidity reference voltage.
By adopting technique scheme, by adopting such scheme, due to when humidity rises, can because there is the change of a humidity, and the state rising gradually or decline, due under the effect of this state, the larger gas of humidity can be made to occur sedimentation phenomenon, and exhaust chamber is set in the below of medical cupboard, by blower fan, gas is circulated, simultaneously circulation time, can play desiccation through hothouse, and when ensure that use, internal gas can carry out timely drying.
