Provided is an aerosol generating device including a case in which a heater for heating a cigarette is installed, a bracket for supporting components installed inside the case, a fastening member for fastening the case and the bracket, and a cap that is installed on an outer surface of the case in an inseparable manner to conceal the fastening member in the case.

A power supply unit for an aerosol inhaler, which includes a power supply configured to discharge electricity to a load that is configured to heat an aerosol generation source and has a correlation between temperature and electric resistance values, includes: a first element connected in series to the load and having a first electric resistance value; a second series circuit that includes a second element having a second electric resistance value, and a third element connected in series to the second element and having a third electric resistance value, the second series circuit being connected in parallel with a first series circuit including the load and the first element; and an operational amplifier connected to the first series circuit and the second series circuit. The first electric resistance value is less than an electric resistance value of the load.

There is provided a non-combustible aerosol delivery system for filtering exhaled breath, the aerosol delivery system including: a power source; a mouthpiece; a removable filter unit; wherein in a first configuration, the filter unit is present and is in engagement with the non-combustible aerosol delivery system to provide an inhalate airflow path, adapted to convey vapor generated by the non-combustible aerosol delivery system to the user during an inhalation, and an exhalate airflow path, adapted to convey breath from the user during an exhalation into the non-combustible aerosol delivery system to the filter unit; wherein in a second configuration, the filter unit is not in engagement with the non-combustible aerosol delivery system.

A heating assembly includes a body defining a heating compartment adapted to receive a vapour generating substance; at least two heaters between which the vapour generating substance is placeable within the heating compartment in use; a movement mechanism adapted in use to move at least one of the at least two heaters between a first and second position, the distance between the at least two heaters being less when the at least one heater is in the first position than when in the second position, wherein the distance between the at least two heaters when the at least one heater is in the first position being such that the separation of the at least two heaters applies pressure to the vapour generating substance when located in the heating compartment; and a switch adapted in use to control the movement of the at least one heater by the movement mechanism.

A device for storing and vaporizing liquid media can comprise an annular liquid media storage tank and a heater configured to vaporize liquid stored in the annular liquid media storage tank.

An e-vapor device may include a reservoir, a heater, and a bimetallic actuator. The reservoir is configured to hold a pre-vapor formulation. The reservoir defines an outlet configured to release the pre-vapor formulation therefrom. The heater is configured to heat the pre-vapor formulation released from the reservoir to generate a vapor. The bimetallic actuator may be configured to seal the outlet of the reservoir when vaping is not occurring and configured to unseal the outlet when vaping is occurring.

The present disclosure provides a personal smoke filter device which comprises a pre-filter element position between the air intake and the filter portion, the pre-filter element being configured to absorb and/or repel moisture in the airflow passing through the device. Additionally, the disclosed personal filter device may be provided with a removable lid to facilitate regular drying of the contents of the smoke filter device. Also provided herein is a specially adapted HEPA filter design for resisting moisture absorption.

The present disclosure relates to an aerosol delivery device that includes a reservoir housing that defines a mouthpiece channel. The aerosol delivery device includes a sealing member configured to be received within the reservoir housing to define a reservoir chamber configured to retain an aerosol precursor composition therein. The aerosol delivery device also includes a substrate member that is configured to be received within the reservoir housing and to be directly engaged with a vaporizing assembly for forming an aerosol. The reservoir housing, sealing member, substrate member, and/or vaporizing assembly can be used for forming aerosols with precise and reproducible compositions.

An electronic vapor provision system includes a control unit and a cartridge configured to engage with and disengage from one another substantially along a longitudinal axis. The cartridge includes a reservoir of liquid to be vaporized, and the control unit includes a battery and a tube portion disposed along said longitudinal axis. The system further includes an induction heating assembly comprising a drive coil and a heater element. The heater element is located in the cartridge for vaporizing the liquid. The cartridge is configured to feed liquid from the reservoir onto the heater element for vaporization. The drive coil is located in the tube portion of the control unit and disposed about the longitudinal axis. The cartridge is located at least partly within the tube portion when engaged with the control unit, such that the heater element is within the drive coil.
