Abstract
An is an aerosol generating device which is capable of generating an aerosol at an appropriate timing includes: a power source which supplies power in order to atomize an aerosol source and/or heat a flavor source; a sensor which outputs a measurement value for controlling the power supplied; and a controller which controls the power supplied on the basis of the measurement value. The controller controls a power supply amount from the power source to be a first value when the measured value is equal to or larger than a first threshold and smaller than a second threshold larger than the first threshold, and the power supply amount to be larger than the first value when the measured value is equal to or larger than the second threshold.
Core Innovation
The invention relates to an aerosol generating device that includes a battery, a container that retains liquid, an atomizer including a porous ceramic structure that holds the liquid at a position and heats the liquid when power is supplied to the atomizer, a pressure sensor, and a controller. The controller uses a signal output by the pressure sensor to regulate the amount of power supplied to the atomizer in order to control triggering and stopping of aerosol generation.
A core aspect is increasing an amount of power supplied from the battery to the atomizer based on sensor output indicating that criteria for triggering generation of the aerosol have been satisfied, and stopping power based on sensor output indicating that the criteria are no longer satisfied, followed by a time condition that is triggered by the output of the pressure sensor. A further concept is using an initial condition related to the pressure sensor signal and then initiating or continuing power supply based on a predetermined amount of time after receiving the pressure sensor signal.
A related concept is monitoring the pressure sensor value to control termination relative to reaching a maximum sensor value. The controller stops power supply based on detecting that the pressure sensor is to pass a maximum value, and does so before a change of the value is completed, or after a user-provided value passes a maximum value and before a change of the value is completed.
Claims Coverage
The independent claims identified in the provided material are clm-00001, clm-00002, clm-00005, and clm-00006. Across these claims, four main inventive features are emphasized.
Pressure-sensor-triggered power increase and sensor-condition stopping with a triggered time condition
The controller increases an amount of power supplied from the battery to the atomizer based on a signal output by the pressure sensor indicating that criteria for triggering generation of the aerosol by the atomizer has been satisfied, and stops power supply based on the pressure sensor indicating that the criteria is no longer satisfied, and after a time condition that is triggered by an output of the pressure sensor is satisfied.
Pressure-sensor-triggered initiation with a predetermined time after the pressure sensor signal
The controller initiates power supply from the battery to the atomizer based on a signal output by the pressure sensor indicating that criteria for triggering generation of the aerosol has been satisfied, and a predetermined amount of time having passed from receiving the signal output by the pressure sensor.
Stopping power before the pressure sensor value change is completed to prevent passing a maximum
The controller stops power supply based on a signal output value by the pressure sensor indicating to pass a maximum value of the pressure sensor, and does so before a change of the value is completed.
Stopping power after exceeding a maximum pressure sensor value but before the change is completed
The controller stops power supply after a value which the pressure sensor detects from a user passes a maximum value and before a change of the value is completed.
The provided independent claims collectively cover pressure-sensor-based control of battery power to a porous-ceramic atomizer for aerosol generation, including triggering and stopping based on whether aerosol-generation criteria are satisfied with a sensor-triggered time condition, initiating power with a predetermined time after receiving a pressure-sensor trigger, and stopping power in relation to a maximum pressure sensor value while ensuring termination occurs before a change of the value is completed.
