Abstract
Systems, devices, and methods may control total particulate matter (TPM) production based on air flow rate and TPM density. TPM density is a TPM production rate per flow rate of gas through an aerosol-generating device. The systems, devices, and methods may measure, or sample, air flow during a puff or draw on an aerosol-generating device. The aerosol-generating device may, in turn, adjust the production of the TPM based on the measured air flow rate and a selected, or desired, TPM density, which may be pre-set in the device and/or subsequently set as desired.
Claims12
A method of controlling a production of a total particulate matter (TPM) in an aerosol-generating device, the method comprising:
- determining a flow rate of a gas through the aerosol-generating device, the determining of the flow rate being performed with a sampling time period between about 1 millisecond and about 200 milliseconds;
- and
- adjusting the production of the total particulate matter (TPM) by the aerosol-generating device in response to the flow rate and a target TPM density such that the adjusting is between about 5 times a second and about 1000 times a second, the target TPM density being a target TPM production rate per flow rate of the gas through the aerosol-generating device.
