Flow transducer 5.3 gathers the flow that described blower fan 5.2 exports, and by the data feedback of collection to processor 2, processor 2 is according to flow transducer 5.3 feedack, export rotation speed of fan and control signal to fan drive circuit 5.1, fan drive circuit 5.1 is according to rotation speed of fan signal, control the rotating speed of blower fan 5.2, to regulate the size of blower fan 5.2 output flow.The flow that flow transducer 5.3 Real-time Collection blower fan 5.2 exports.
Flow transducer 5.3 of the present invention is air flow sensor, for gathering the air mass flow that blower fan 5.2 exports.Air flow sensor of the present invention converts the air mass flow of the blower fan 5.2 of suction to the signal of telecommunication, then deliver to processor 2, to be controlled the flow that blower fan 5.2 exports by processor 2.It is several that the structural shape of existing common air flow sensor can be divided into vane type, amount core type, hot wire type, hot diaphragm type, karman vortex rotating etc., and the present invention specifically adopts the air flow sensor of which kind of structural shape, selectes according to actual needs.
Temperature sensor 4.2 is sticked on heating plate 4.3 by heat-conducting metal.Heat-conducting metal has heat-conductive characteristic, and its conduction of heat is mainly realized by the motion of electronics.By the heat conductivity of heat-conducting metal, the temperature transfer of heating plate 4.3 is to temperature sensor 4.2, and temperature sensor 4.2 just can record the temperature of heating plate 4.3 in real time.
Temperature sensor 4.2 gathers the temperature of heating plate 4.3, and by the data feedback of collection to processor 2, processor 2 is according to temperature sensor 4.2 feedack, export heating plate and control signal to heating control circuit 4.1, heating control circuit 4.1, according to heating plate control signal, regulates the temperature of heating plate 4.3.When the temperature of heating plate 4.3 does not reach the temperature of the heating gear preset, processor 2 is according to temperature sensor 4.2 feedack, after analyzing and processing, export a heating plate and control signal to heating control circuit 4.1, with the temperature regulating heating plate 4.3 to heat, until the temperature of heating plate 4.3 reaches the temperature of the heating gear preset.
Temperature sensor 4.2 refers to can experience temperature and the sensor converting usable output signal to.Temperature sensor 4.2 can be divided into contact and contactless two large classes by metering system, is divided into thermal resistance and thermocouple two class according to sensor material and electron component characteristic.
The detecting portion of contact type temperature sensor and measurand have good contact, also known as thermometer.Thermometer reaches thermal balance by conduction or convection current, thus makes the temperature of the indicating value energy direct representation measurand of thermometer.Sensing element and the measurand of non-contact temperature sensor are not in contact with each other, also known as non-contact type thermodetector table, this instrument can be used to measurement moving object, Small object and thermal capacity is little or the surface temperature of rapid (transition) object of variations in temperature, also can be used for the Temperature Distribution of measuring tempeature field.
Thermal resistance temperature sensor utilizes the resistance value of conductor or quasiconductor to vary with temperature and the principle changed carries out a kind of sensor temperature meter of thermometric.Thermal resistance is primary element variations in temperature being converted to resistance change, usually needs resistance signal to be delivered on Computer Control Unit or other primary instrument by lead-in wire.Thermocouple temperature sensor is by two kinds of different conductors or semiconductor group synthesis closed-loop path, when the temperature of two kinds of different conductors or semiconductor link is different, just has electric current to produce, namely produce thermo-electromotive force in loop in this closed-loop path.Usually thermoelectrical potential signal is passed on Computer Control Unit or other primary instrument by lead-in wire.
Temperature sensor 4.2 of the present invention, preferably, adopts thermal resistance temperature sensor or thermocouple temperature sensor.The change of heating plate 4.3 temperature is changed into the change of resistance value by thermal resistance temperature sensor, and the change of resistance value is fed back to processor 2, processor 2, according to the resistance value of feedback, exports heating plate and controls signal to heating control circuit 4.1, control the temperature of heating plate 4.3.Thermocouple temperature sensor converts the change of heating plate 4.3 temperature the change of electromotive force to, and the change of electromotive force is fed back to processor 2, processor 2, according to the electromotive force of feedback, exports heating plate and controls signal to heating control circuit 4.1, control the temperature of heating plate 4.3.
