To be controlled according to set operator scheme for example, by on-off circuit SW1 and SW2.On-off circuit SW1 and SW2 are not
The different operator scheme with off state correspondence.
Temperature sensor is illustrated as including NTC thermistor 441.NTC thermistor 441 is used for sensing through second
Gas flow temperature after the heating of heater 432, and the change of gas flow temperature is converted into corresponding voltage change.
Temperature controller is illustrated as including the analog control circuit of operational amplifier 451 and variable resistance 452.Computing
The comparison voltage input of amplifier 451（Terminal above in Fig. 4）Input the ratio corresponding with the gas flow temperature sensed
Compared with voltage（Vin）.The reference voltage input terminal of operational amplifier 451（Terminal below in Fig. 4）Input and default threshold value

The comparison voltage input of operational amplifier 451 is connected to NTC thermistor 441 in Fig. 4, to receive NTC heat
The voltage signal for the gas flow temperature that instruction on quick resistance 441 is sensed.Because the resistance value of NTC thermistor increases with temperature
And reduce, so when the gas flow temperature increase sensed, the resistance value of NTC thermistor 441 reduces, correspondingly NTC temperature-sensitives
Voltage Vin on resistance 441 reduces, and vice versa.In certain embodiments, if Vin drops below Vref, sensing is shown
The gas flow temperature arrived is more than threshold temperature, then operational amplifier can export 0V voltages in output end so that secondary heater 432 subtracts
Its small heating amount, such as power off secondary heater 432 to stop heating air-flow., whereas if Vin is equal to or more than
Vref, shows that the gas flow temperature sensed is less than threshold temperature, then operational amplifier 451 will export 5V voltages in output end, make
Obtain secondary heater 432 and increase its heating amount, such as secondary heater 432 is powered with to starting air-flow heating.In some realities

Resistor 452 is connected, and can obtain the reference more changed by fine-tuning the resistance value of variable resistance 452
Level, is derived from more desired threshold temperatures.Here, because comparative results different from threshold temperature can trigger fortune
The change of the output signal of amplifier is calculated, so threshold temperature is also referred to as the triggering temperature of operational amplifier.In an example
In, when triggering temperature（It is set according to corresponding target temperature）When relatively low, after secondary heater energization, second adds
Hot device will take for the short period and reach target temperature.Operational amplifier, which will be triggered, afterwards closes secondary heater, until NTC
Thermistor senses air-flow and reaches the relatively low triggering temperature, then, and operational amplifier will be again triggered and add to second
Hot device power-up.When triggering temperature is higher, after secondary heater energization, secondary heater will need the longer time to reach
To target temperature, therefore circulation time between its corresponding heater status conversion will be than setting during relatively low triggering temperature more
It is long.In one embodiment, triggering temperature may include the upper limit threshold and lower threshold corresponding with target temperature, wherein working as sense
When the gas flow temperature measured reaches at or above upper limit threshold, operational amplifier will be triggered and give secondary heater power-up, and work as
When the gas flow temperature sensed is at or below lower threshold, operational amplifier will be again triggered and stop to secondary heater
Power-up.The upper limit threshold and lower threshold are calculated based on target temperature.For example, when target temperature is T, the upper limit
Threshold value can be T+x, and lower threshold can represent certain temperature variation for T-y, wherein x and y, and can be according to tool
The circuit realiration of body is correspondingly set.

In Fig. 5, the curve on top represents the temperature output of hair-dryer, and lower waveform is then represented from temperature controller output to control
Make the control signal of the heating amount of the second heating component, be for example coupled to secondary heater operational amplifier output 0V-
5V voltage signals.
As shown in figure 5, reaching upper limit threshold temperature when gas flow temperature rises（It is exported with the desired temperature of hair-dryer
And change）When, the voltage of operational amplifier output is changed into 0V, and the second heater block stops heating air-flow.And when air-flow temperature
Degree drops to lower threshold temperature（It exports and changed with the desired temperature of hair-dryer）When, voltage will be changed into 5V again,
And second heater block start to air-flow heat.
In Figure 5, in the left part of temperature curve of output, i.e., within the period of such as about 0-34 seconds, institute
Desired temperature output has higher temperature, than such as from about 65 DEG C.In this case, due to needing longer time to add air-flow
Heat is to this temperature, so the cycle period of the state switching for the control signal that temperature controller is exported is longer.It is defeated in temperature
Go out in the right part of curve, i.e., within the period of such as about 73-103 seconds, desired temperature output has relatively low
Temperature, than such as from about 45 DEG C.In this case, it is only necessary to which air-flow is heated to this temperature by the shorter time, so temperature control
The cycle period for the control signal that device processed is exported is shorter.
