Problems solved by technology
[0004] However, when the processor etc. that control the heater fails, the heater still generates heat
In this case, the heating method of the heater will be different from the temperature distribution curve, not only cannot provide the best taste to the user, but also cause problems in the safe use of the aerosol generating device

Embodiment Construction
[0022] An aerosol generating device according to one embodiment includes: a heater, a first switch electrically connected in series with the heater, a second switch connected electrically in series with the heater and the first switch, a first processor, and an output a first control signal controlling the opening and closing state of the first switch, and a second processor communicating with the first processor and outputting a second control signal controlling the opening and closing state of the second switch; The second processor outputs the second control signal to change the on-off state of the second switch according to the communication state with the first processor.
[0023] In the above aerosol generating device, the second processor outputs the second control signal to turn off the second switch when the communication state with the first processor is poor.
[0024] In the above-mentioned aerosol generating device, the first processor outputs the first control sig...

An aerosol-generating device, according to one aspect, comprises: a heater; a first switch electrically and serially connected to the heater; a second switch electrically and serially connected to theheater and the first switch; a first processor for outputting a first control signal for controlling an opened / closed state of the first switch; and a second processor for communicating with the first processor, and outputting a second control signal that controls an opened / closed state of the second switch, wherein the second processor outputs the second control signal according the state of thecommunication with the first processor so that the opened / closed state of the second switch changes.
Description
technical field [0001] It relates to an aerosol generating device, and more specifically, to an aerosol generating device for cutting off heat generated by a heater due to abnormal operation of a processor or the like. Background technique [0002] Recently, demands for alternatives to overcome the disadvantages of conventional cigarettes are increasing. For example, there is increasing demand for a method of generating an aerosol by heating an aerosol-generating substance inside a cigarette instead of generating an aerosol by burning the cigarette. Accordingly, studies on heated cigarettes and heated aerosol generators are actively being conducted. [0003] The heater of the aerosol generating device heats the cigarette inserted into the aerosol generating device. The aerosol generating device can control power supplied to the heater based on a preset temperature profile. [0004] However, when a processor or the like that controls the heater fails, the heater still gene...
