AI Technical Summary

Problems solved by technology

However, even if the user heats the heater of the aerosol generating device by inputting the heating switch, the temperature of the heater does not rise, and there is a problem that it is difficult for the main control unit to determine the cause, that is, the heater is disconnected. The temperature of the heater does not rise, or the temperature of the heater rises but the rising temperature cannot be detected due to a defect in the temperature sensor

Embodiment Construction

[0018] The aerosol generating device of an embodiment of the present invention for solving the technical problem is characterized in that it includes: a heater for generating an aerosol by heating an aerosol generating substrate; a control signal for power supplied by the heater; a switch for supplying power to the heater by performing a switching operation based on the control signal; and a comparison signal calculation unit for receiving a signal based on the switching operation to calculate a comparison target signal. The control unit compares the comparison target signal with a reference signal, and generates a cut-off signal for interrupting the switching operation of the switch if the calculated comparison value exceeds a preset range.

[0019] In the device, it is characterized in that the control signal is a pulse width modulation (digital pulse width modulation) signal.

[0020] In the device, it is characterized in that the reference signal is a pulse width modulatio...

Abstract

According to one embodiment of the present invention, an aerosol generating device comprises: a heater for generating aerosol by heating an aerosol generating substrate; a control part for controllingpower supplied to the heater by a battery based on a control signal; a switch for supplying power to the heater by performing a switching operation according to the control signal; and a comparison signal calculation part for receiving a signal by the switching operation and calculating a comparison object signal. Disclosed is the aerosol generating device having a feedback control function, wherein the control part generates a cut-off signal for stopping the switching operation of the switch when a comparison value calculated by comparing the comparison object signal with a reference signalexceeds a preset range.

Description

technical field [0001] The present invention relates to an aerosol generating device and a method for realizing its feedback control function, more specifically, to the following method and an aerosol generating device using the method: it is indispensable to include in the control part of the aerosol generating device, The overall stability of the operation of the aerosol generating device can be increased by receiving the response signal to the control signal and using it to generate the control signal to be output at the next point in time. Background technique [0002] In recent years, there has been an increasing demand for alternatives to overcome the disadvantages of conventional cigarettes. For example, there is increasing demand for a method of generating an aerosol by heating an aerosol-generating substance inside a cigarette, which is different from a method of generating an aerosol by burning a cigarette. Therefore, studies on heating-type cigarettes and heating...
