An electronic cigarette comprises a battery portion which is operable to provide power to a heating element of the electronic cigarette, and a cartomizer coupled with the battery portion. The cartomizer comprises a liquid container which provides a liquid toward the heating element wherein the liquid is used for producing and flavoring a vapor of the electronic cigarette when the liquid is heated by the heating element, and a memory which is operable to record and store an amount of the liquid remaining in the liquid container.

A cartridge for an aerosol-generating system includes a sensor including a capacitor with a first capacitor plate and a second capacitor plate, a storage portion for storing an aerosol-forming substrate, and a vaporizer. The storage portion is between the first capacitor plate and the second capacitor plate. The permittivity of the liquid storage portion changes upon a change of the volume of the liquid aerosol-forming substrate held in the liquid storage portion. The sensor is configured to measure the capacitance of the capacitor. The measured capacitance relates to a corresponding permittivity of the aerosol-forming substrate held in the storage portion so that the amount of the volume of the aerosol-forming substrate held in the storage portion is determinable from the measured capacitance.

An aerosol-generating system may include a liquid storage portion configured to hold liquid aerosol-forming substrate, a vaporizer including a heating element with an internal passage at least partially defined by a surface of the heating element, and a micro pump configured to deliver liquid aerosol-forming substrate from the liquid storage portion to the internal passage of the heating element, such that the vaporizer is configured to heat the delivered liquid aerosol-forming substrate at the internal passage to a temperature sufficient to volatilize at least a part of the delivered liquid aerosol-forming substrate. The micro pump may be configured to deliver a particular amount of liquid aerosol-forming substrate to the internal passage based on the micro pump performing an individual pump cycle.

An aerosol-generating device may include a housing having flexible portion along its length. The flexible portion is configured to transition between a relaxed or unloaded configuration and a flexed or deflected configuration. A flexible heating element and mouthpiece may also be disposed in the housing. When the housing is in a relaxed or unloaded configuration, the flexible heating element and the mouthpiece are at least partially longitudinally aligned with the flexible portion of the housing.

An aerosol-generating system includes an electric heater, a battery and control circuitry. The electric heater is configured to vaporize an aerosol-forming substance. The battery is configured to power the electric heater. The control circuitry is configured to: prevent charging of the battery in response to detecting that the electric heater is in an operation state; or prevent operation of the electric heater in response to detecting that the battery is in a charging state.

A cartridge of an e-vaping device includes a housing extending in a longitudinal direction, a reservoir in the housing, a heater in the housing, and an absorbent material at least partially surrounding the sinusoidal shaped member. The reservoir is configured to store a pre-vapor formulation. The heater has a sinusoidal shaped member translating about an elliptical shape to define a channel there through. The absorbent material is in fluid communication with the reservoir.

An aerosol delivery device and a substrate tablet for use with an inductively-heated aerosol delivery device are provided. The aerosol delivery device comprises a control body having a housing, a mouthpiece portion located proximate the housing, a resonant transmitter located in the control body, a control component configured to drive the resonant transmitter, and a substrate tablet receivable in the device. The substrate tablet may comprise a granular substrate material and a susceptor component, the substrate material and the susceptor component may be configured to be formed together, and the susceptor component may be configured to be heated by the resonant transmitter.

Certain aspects of present invention relate to electronic cigarettes. In certain embodiments, the electronic cigarettes may include a vaporizer and e-liquid storage tank combo, and a power module. The vaporizer and e-liquid storage tank combo may include a heating element having a positive terminal and a negative terminal to receive electrical energy from a battery of the power module to heat e-liquid in direct contact with surfaces of a cylindrical vaporizer and a vaporizer connector having a circular base and the circular base having an external multiple threads connector. The power module may have a power connector having the battery, a positive terminal, a negative terminal, and an internal multiple threads connector. The external multiple threads connector of the vaporizer and e-liquid storage tank combo is threadedly connected to the internal multiple threads connector of the power connector of the power module.

A vaporiser assembly for an aerosol-generating system may include a capillary element made from porous glass. The capillary element has a first end and a second end. The vaporiser assembly further comprises a heater element. The first end of the capillary element is configured to be fluidically connected to a liquid storage portion. The heater element is provided at the second end of the capillary element. The pore size of the capillary element is configured to allow a liquid aerosol-forming substrate from the liquid storage portion to be conveyed from the first end to the second end of the capillary element by capillary action. The capillary element has a pore size gradient such that an average pore size of the capillary element transitions or varies from larger pores at the first end of the capillary element to smaller pores at the second end of the capillary element.

A yogurt fermentation system comprising a flexible insulated cover configured to cover and contact the sides of a yogurt culture container containing a yogurt culture; a heating element dispersed within the flexible insulated cover; a temperature regulator configured to regulate the heating element and maintain a temperature sufficient to ferment the yogurt culture, and methods of culturing yogurt using said system.
