Electron Aerosol Delivery System

Abstract

An aerosol supply system for generating an aerosol from a source liquid, the aerosol supply system comprising: a reservoir of source liquid; a planar evaporator including a planar heating element (455, 555, 655), wherein the evaporator is configured to draw source liquid from the reservoir to near the evaporation surface of the evaporator by capillary action; and an induction heating coil operable to induce current in the heating element to inductively heat the heating element and thus near the evaporation surface of the evaporator A portion of the source solution was evaporated. In some examples, the evaporator also includes a porous filler / wicking material, e.g., a non-conductive fibrous material at least partially surrounding the planar heating element (susceptor) and in contact with the source liquid from the reservoir, to provide or at least have A function that helps draw the source liquid from the reservoir to near the evaporating surface of the evaporator. In some examples, the planar heating element (susceptor) itself may comprise a porous material to provide or at least facilitate the function of drawing source liquid from the reservoir to near the evaporation surface of the evaporator.

Description

technical field [0001] The present invention relates to electronic aerosol delivery systems, such as electronic nicotine delivery systems (eg electronic cigarettes). Background technique [0002] figure 1 is a schematic diagram of an example of a traditional electronic cigarette 10 . The electronic cigarette has a generally cylindrical shape, extending along a longitudinal axis indicated by the dashed line LA, and comprising two main components, namely a control unit 20 and a cartomiser 30 . The nebulizer includes: an internal chamber including a reservoir of a liquid formulation containing nicotine; a vaporizer (such as a heater); and a mouthpiece 35. The nebulizer 30 may also include a wick or similar device to carry a small amount of liquid from the reservoir to the heater. The control unit 20 includes a rechargeable battery that powers the electronic cigarette 10 and a circuit board for generally controlling the electronic cigarette. When the heater receives power fr...

AI Technical Summary

Problems solved by technology

However, making the nebuliser refillable poses potential problems, for example, the user may attempt to refill the nebuliser with an inappropriate liquid (liquid not provided by the supplier of the e-cigarette)

There is a risk that such unsuitable liquids could result in a poor customer experience, and / or could be potentially dangerous, by causing damage to the e-cigarette itself or possibly by producing toxic vapors

[0010] Therefore, existing methods for reducing the cost of disposable components (or for avoiding the need for such disposable components) have had limited success
