Embodiment Construction

[0058] figure 1 An example of an electrically operated aerosol generation system with a liquid storage portion is shown. exist figure 1 , the system is a smoking system. figure 1 The smoking system 100 includes a housing 101 having a mouthpiece end 103 and a body end 105. In the body end, a power supply in the form of a battery 107 and a circuit 109 are provided. The puff detection system 111 is also arranged to cooperate with the circuit 109 . In the mouthpiece end, a liquid storage section in the form of a box 113 containing liquid 115, a capillary wick 117 and a heater 119 are provided. Note that in figure 1 The heater is only shown schematically. exist figure 1In the exemplary embodiment shown in , one end of capillary wick 117 extends into cassette 113 and the other end of capillary wick 117 is surrounded by heater 119 . The heater is connected to the circuit via a connector 121 that can pass along the outside of the box 113 ( figure 1 not shown). The housing 10...

Abstract

The invention provides an electrically operated aerosol generating system (100) for receiving an aerosol - forming substrate (115). The system comprises a liquid storage portion (113) for storing liquid aerosol - forming substrate, an electric heater (119) comprising at least one heating element for heating the liquid aerosol - forming substrate, and electric circuitry (109) for determining depletion of liquid aerosol- forming substrate heated by the heater based on a relationship between a temperature of the heating element and power applied to the heating element. There is also provided a method in an electrically operated aerosol generating system comprising a liquid storage portion for storing liquid aerosol - forming substrate and an electric heater comprising at least one heating element for heating the liquid aerosol - forming substrate, the method comprising: determining depletion of liquid aerosol - forming substrate heated by the heater based on a relationship between a temperature of the heating element and power applied to the heating element.

Description

technical field [0001] The present invention relates to an electrically operated aerosol generation system. In particular, the present invention relates to an electrically operated aerosol-generating system in which the aerosol-forming substrate is a liquid and is contained in a liquid storage portion. Background technique [0002] WO2009 / 132793A1 discloses an electrically heated smoking system having a liquid storage portion. The liquid storage portion includes an aerosol-forming substrate and is connected to a vaporizer including an electric heater powered by a battery power source. In use, the electric heater is activated by the user smoking the mouthpiece to switch on battery power. The heated aerosol-forming substrate contained in the vaporizer will be vaporized. The user smokes the mouthpiece causing suction air along or through the vaporizer, creating an aerosol, as known to those skilled in the art, which are solid particles or droplets in a gas (eg, air) suspend...
