[0005] On the basis of the above scheme and as the preferred scheme of the above scheme: the control module is provided with a temperature acquisition unit, a timing unit, a temperature processing unit, a storage unit and a start -stop control unit;
[0006] The temperature acquisition unit is used for receiving the real-time temperature collected by the temperature sensor;
[0007] The temperature processing unit is used for calculating the change value of the temperature in unit time and comparing with the temperature threshold value in the storage unit;
[0008] The start -stop control unit controls the start and stop of the atomizer body according to the comparison result.
[0009] On the basis of the above scheme and as the preferred scheme of the above scheme: the gas guide pipe has two independent channels, one channel is an atomization channel, and the other channel is a wiring channel; the temperature sensor and the control module are electrically connected through wires, and the wires are arranged in the wiring channel.

[0012] The working principle of the utility model is as follows: when a patient uses the atomizer, the mask is attached to the face of the patient, when the patient exhales, the exhaled gas temperature is higher than the original temperature of the mask, therefore, the temperature sensor should check that the gas temperature rises within a certain time; similarly, when the patient starts to inhale, the gas in the mask will have a temperature drop. Therefore, when the temperature sensor detects that the gas temperature in the mask appears periodic fluctuation, it can be determined that the patient is using the atomizer, and the atomizer is working normally.
