Description

Method for judging insertion state of aerosol substrate and aerosol generating device Technical Field The invention relates to the technical field of aerosol generating devices, in particular to a method for judging an aerosol substrate insertion state and an aerosol generating device. Background Aerosol generating devices typically require an automatic start-up of the heating process after insertion of the aerosol substrate and a shut-down of the operation when the aerosol substrate is withdrawn to achieve a convenient user experience. In the prior art, an aerosol substrate mostly adopts an infrared sensor to detect the insertion state of the aerosol substrate. Specifically, the output value of the infrared receiver will vary with whether the aerosol matrix is inserted, as the infrared value collected in real time is typically compared to a preset intermediate value. When the infrared value is greater than or less than the threshold value, the aerosol substrate is judged to be in an inserted or extracted state respectively. However, in practical application environments, the infrared signal is often affected by many factors, such as ambient light interference, differences in internal reflectivity of the aerosol matrix, differences in material quality of the aerosol matrix, and aging of the sensor, so that the infrared value may randomly fluctuate around the threshold value. When the infrared value frequently shakes up and down around the set threshold value, the aerosol matrix can be misjudged to be repeatedly inserted and pulled out, and the heating module is caused to be started or stopped frequently. This not only affects the user's use experience, but may also lead to increased energy consumption, shortened heating module life and potential safety hazards.
