Embodiment Construction

[0062] figure 1 One example of an electrically operated aerosol generating system with a liquid storage portion is shown. exist figure 1 where the system is a smoking system. figure 1The smoking system 100 includes a housing 101 having a mouthpiece end 103 and a body end 105 . A power source in the form of a battery 107 and an electrical circuit 109 is provided in the body end. A smoking detection system 111 is also provided in cooperation with the circuit 109 . In the mouthpiece end are provided: a liquid storage portion in the form of a cartridge 113 containing a liquid 115 ; a capillary wick 117 ; and a heater 119 . It should be understood that the heater is only figure 1 Indicated. exist figure 1 In the example embodiment shown, one end of the capillary wick 117 protrudes into the cartridge 113 and the other end of the capillary wick 117 is surrounded by a heater 119 . The heater is connected to the circuit through a connector 121 which can pass along the outside o...

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) configured to monitor activation of the electric heater and estimate an amount of liquid aerosol - forming substrate remaining in the liquid storage portion based on the monitored activation. 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: monitoring activation of the electric heater and estimating an amount of liquid aerosol - forming substrate remaining in the liquid storage portion based on the monitored activation.

Description

technical field [0001] The present invention relates to an electrically operated aerosol generating system. In particular, the present invention relates to an electrically operated aerosol generating system wherein the aerosol-forming substrate is a liquid contained in a liquid storage portion. Background technique [0002] WO2007 / 078273 discloses an electric smoking appliance. The liquid is stored in a container that communicates through a series of small holes with a heater evaporator powered by battery power. The heater is in the form of a helically wound electric heater mounted on an electrically insulating support. In use, the heater is activated by the user's mouth to connect to battery power. The user's draw on the mouthpiece causes air to be drawn into the mouthpiece and then into the user's mouth, above the heater vaporizer, through the holes in the container. [0003] There are several advantages to prior art electrically operated aerosol generating systems, in...
