Heating inhaler and controlling method thereof

A method of controlling a heating inhaler, wherein the heating inhaler comprises a power source configured to supply power to the heating inhaler, an atomizer detachably connected to the power source, a sensing element, an indicating element, and a control circuit board;

• the power source, the atomizer, the sensing element, and the indicating element are electrically coupled to the control circuit board when the atomizer is assembled to the power source;
• the method comprises:
• step S101:
• detecting, by the sensing element, a suction action, performing step S102 upon detecting the suction action within a first predetermined time period;
• otherwise, performing step S103;
• step S102:
• controlling, by the control circuit board, the power source to supply power to the atomizer for a second predetermined time period, and then to stop supplying power to the atomizer, wherein the indicating element displays a first state within the second predetermined time period until the power source stops supplying power to the atomizer, then the indicating element displays a second state;
• and
• step S103:
• controlling, by the control circuit board, the power source to stop supplying power to the atomizer, and displaying, by the indicating element, the second state;
• further comprising step S203:
• determining, by the control circuit board, a time interval between a time at which the atomizer is electrically coupled to the power source and the time at which the sensing element detects a suction acution in a previous time is greater than a third predetermined time period, performing the step S101 upon determining that the time interval is greater than the third predetermined time period;
• otherwise, controlling, by the control circuit board, the power source to stop supplying a power to the atomizer, and the indicating element displaying a third state;
• wherein the first predetermined time period ranges from 10 minutes to 20 minutes, the second predtermined time period ranges from 1.5 seconds to 2.5 seconds, and the third predetermined time period ranges from 25 minutes to 35 minutes.
