To N-type Darlington transistor Q2 cut-in voltage when, N-type Darlington transistor Q2 conducting heatings, the electric energy that consumption motor U1 is produced, and the N
Type Darlington transistor Q2 is operated in linear zone, then, the electric current of emitter e 1 is exactly β times of base stage b1 electric currents, wherein, β reaches for N-type
Islington pipe Q2 current amplification factor, for example, can be 100, so, the power consumption of heating unit is mainly generated in N-type Darlington
On pipe Q2, first resistor R1 power consumption very little can be ignored, in this way, it is possible to the utilization rate of energy is improved, and N-type Darlington
Pipe Q2 is operated in linear zone, can obtain the cut-in voltage of more accurate heating unit, is easy to implement and electromotive force is recycled

Darlington transistor Q2 is turned off.
Further, in order to cause heating unit U2 only motor U1 produce electric energy when just in humidification machine
Liquid is heated, and heating unit U2 cut-in voltage can be caused to be higher than the supply voltage that power end VCC is provided.Due to power end
VCC provide supply voltage potentially unstable, can fluctuate within the specific limits, therefore, in order that motor U1 is not producing electric energy
