（ｃ）参照〕。Next, the adjustment of the atomizing liquid temperature (room temperature) in the bottle and the aerosol temperature will be described with reference to FIG. However, a temperature sensor is used to detect the atomized liquid temperature, and the horn itself is used as a temperature sensor in order to detect the aerosol temperature more directly and facilitate feedback.
The temperature will be controlled. Applying power to the heater, while being determined by the difference between the atomized liquid temperature t 0 at room temperature and at a set temperature t a of the aerosol (t a -t 0), the aerosol temperature t constantly monitored by the temperature sensor, Aerosol temperature t
There is controlled to match the set temperature t a [see (a) of FIG. 4]. Such feedback is always provided. As the control of the heater itself, the current flowing through the heater is controlled [see (b) of FIG. 4], or the energization of the heater is turned on / off, and the power is adjusted by Pul.
It may be performed by controlling the se duty (see (c) of FIG. 4).

The characteristic of the aerosol temperature is as shown in FIG. That is,
As described above, atomization is started at the same time when the power is turned on, and the aerosol temperature t at the start of atomization is room temperature t 0 (the temperature of the atomizing liquid in the bottle), but the liquid supply nozzle is small and its heat capacity is high. Is relatively small, the temperature of the liquid supply nozzle rises in a short time. Further, since the amount of atomized liquid that passes through the liquid supply groove of the liquid supply nozzle is very small, it is immediately heated by the liquid supply nozzle, and as a whole, the time for the aerosol temperature t to reach the set temperature t 1 is shortened. Moreover, since feedback is structurally easy and the temperature rise of the entire device is small, there is almost no temperature fluctuation and stable after the aerosol temperature t reaches the set temperature t 1 .

大きさのために反応が遅くなる。On the other hand, in the aerosol temperature characteristic of the conventional inhaler shown in FIG. 8, not only a certain time (T 0 ) is required from power-on to the start of atomization, but also the aerosol temperature after atomization is started. It takes a long time for t to rise to the set temperature t 1 . Moreover, since the power of the heater is large, when continuously operated, the aerosol temperature t also rises with time as the temperature of the entire device rises,
It becomes higher than the set temperature t 1 . Also, with respect to the feedback to the disturbance, the reaction becomes slow due to the large heat capacity of the heater and the device.
