1. An electronic cigarette vaporiser system that includes an electronic vaporiser, a heating element in the electronic vaporiser, and a microcontroller;
- in which the microcontroller monitors or measures the airflow speed or pressure drop over an air-pressure sensor or other sensor and uses that as an input to control the power delivered to the heating element;
in which the electronic vaporiser system includes (i) a user-replaceable, e-liquid cartridge, which is not user-refillable and includes no heating element; and
(ii) an e-liquid reservoir that is separate from the user-replaceable e-liquid cartridge; and
(iii) an electric or electronic pump that is configured to withdraw e-liquid from the user-replaceable e-liquid cartridge and pump pressurized e-liquid to the e-liquid reservoir; and
wherein the heating element that is in the electronic vaporiser is in, or in e-liquid communication with, the e-liquid reservoir.

Abstract
An electronic cigarette vaporiser includes a heating element and a microcontroller; the microcontroller monitors or measures the airflow speed or pressure drop over an air-pressure sensor or other sensor and uses that as an input to control the power delivered to the heating element. The microcontroller can compensate for a very strong inhalation by applying more power during that inhalation as compared to a very light inhalation to ensure that the heating element is kept at its optimal heating temperature.
