Each parts effect: resistance R1 plays hypotensive effect, diode D1 plays halfwave rectifier effect, stabilivolt D2 plays slicing pressure stabilization function, electric capacity C1 strobes.
Temperature detecting module 2 is used for detecting current drying the temperature inside the box and exporting the first reference signal, it adopts thermocouple K, thermocouple K detects Current Temperatures and is converted into the first reference signal (the first reference signal substantially voltage signal), the 3. foot (i.e. in-phase input end) of the first reference signal input comparator IC1.
Comparison module 3 is used for by the first reference signal compared with threshold signal (preset temperature value), and exports corresponding second reference signal according to comparative result. Comparison module 3 includes threshold circuit 31 and comparator IC1. Rheostat W1 that threshold circuit 31 includes being sequentially connected in series, resistance R2, rheostat W2, resistance R3, the other end of rheostat W1 correspondence resistance R2 couples the connection node of diode D1 and electric capacity C1, the other end ground connection of resistance R3 correspondence rheostat W2. The moved end of rheostat W2 couples the 2. foot (i.e. inverting input) of comparator IC1. 2. the signal of foot input is threshold signal (threshold signal is substantially also for voltage signal). Comparator IC1 adopts LM3582 chip, and 3. foot couples thermocouple K output by resistance R4. 1. foot output couples 2. foot input by resistance R5, and the effect of resistance R5 is that a little part for input is fed back to in-phase input end 3. foot, so that output locking is constant when small-signal fluctuates.
