An electronic cigarette particularly adaptable to vaporize liquid material also having exhale filter function is disclosed herein. The exhale function is useful to prevent second hand smoke in an enclosed environment, for example. An innovative diverter valve assembly comprises a unique duckbill valve configuration diverting air through a cooker chamber and into a mouthpiece in an inhale function and diverting exhaled air around the cooker chamber in the exhale function and through a filter assembly. A preferred embodiment further introduces a unique shape to the smoking instrument being elliptical in the cross-section and tapering to proximal and distal ends.

An aerosol-generating system is provided, including: a cartridge assembly including a cartridge having an upstream end and a downstream end, and a ventilation air inlet positioned downstream of the cartridge; and an aerosol-generating device including a housing defining a device cavity configured to receive an upstream end of the cartridge assembly, an electric heater configured to heat the cartridge when the cartridge assembly is received within the device cavity, a power supply, and a controller configured to control a supply of electrical power from the power supply to the electric heater, the system being configured so that, when the upstream end of the cartridge assembly is received within the device cavity, the ventilation air inlet is positioned within the device cavity and a portion of an internal surface of the device cavity overlying the ventilation air inlet is spaced apart from the cartridge assembly.

A wearable vaporization system (100) is provided that includes a vaporization device (110) having a mouthpiece outlet portion (172) from which a vaporized composition mixed with air is withdrawn. The wearable vaporization system (100) further includes a vaporizer holder (130) that is releasably securable to a wrist of a user. The vaporizable holder (130) has a longitudinally extended cradle (132) and a receiving space (138) disposed thereon. One of the vaporization device (110) or the vaporizer holder includes a detent arrangement (121, 121a, 121b, 121c, 145) and the other of the vaporizer holder (130) or the vaporization device (110) includes at least one corresponding detent receiving recess (140a, 140b, or 142, 144 or 126, 128) for releasably retaining the vaporization device against lateral sliding displacement relative to the vaporizer holder (130).

An atomizer changes the inflow and outflow direction by adding a shunt tube. The external air passes through the bottom of the atomizing chamber to the top of the atomizing chamber, carrying out the smoke in the atomizing chamber. In another atomizer, the air outlet pipe extends directly to the bottom of the atomizing chamber, where it is connected to the air inlet passage in the air intake member. As such, the smoke in the atomizing chamber can be carried out by the external air.

A device capable of automatically igniting or heating a cigarette includes a heat source system, a control system, and the openable and closeable top cover. The heat source system includes the electric heating chamber and the igniter. The igniter includes the electric heating element. The electric heating chamber includes at least one pair of light passing holes of the electric heating chamber. The control system includes the control circuit board, the mechanical switch, the mode switching switch, the infrared light source, the light sensing switch, and the device main circuit switch. The mechanical switch controls the top cover to be opened or closed and controls the device main circuit switch to be turned on or off. The mode switching switch is used for switching between an operation of the igniter and an operation of the electric heating chamber.

An electronic cigarette, including: an atomization assembly and a battery assembly. The atomization assembly is disposed on the battery assembly. The atomization assembly includes a mouthpiece; an atomizer; a first cover; a first silicone seal; a second silicone seal; a stainless iron. The battery assembly includes a third silicone seal; a support frame; an electrode assembly; a light pipe; a first silicone ring; a pneumatic switch; a baffle plate; a battery; a power button; a gasket; a button board; a printed circuit board; a first bracket; a second silicone ring; a vacuum tube; a piece of thermal insulation cotton; a polyimide tube; a heating tube; a second bracket; a housing; a support; a clamp spring; a second cover; a base; and a plurality of ceramic heaters. The first silicone seal is embedded in the first cover. The stainless iron is embedded in the mouthpiece.

A cartridge for an aerosol-generating system is provided, including a storage portion to hold a liquid aerosol-forming substrate; and a heater assembly including an electrical heating element to heat the substrate to form aerosol, and a capillary body to convey the substrate to the element disposed at a porous outer surface of the body, the storage portion being at a first portion of the cartridge, a first airflow channel being at another portion of the cartridge adjacent to the element and defining a first airflow path extending from an air inlet toward the element in a first direction, a second airflow channel defining a second airflow path extending toward the element in a second direction, and a third airflow channel defining a third airflow path extending from the element toward an air outlet in a third direction and to convey aerosol, and the first, second, and third directions are different.

An aerosol generating device, includes an inhalation outlet; a chamber for holding a material, the material capable of generating a vapour when heated; a heater for heating material held in the chamber; an air inlet connected by an air inlet passage to the chamber; a vapour-cooling module providing a fluidic connection between the chamber and inhalation outlet, the module configured to cool a vapour passing there through. Suction at the inhalation outlet causes air to enter the chamber via the air inlet, thereby transporting vapour generated in the chamber through the module to the inhalation outlet, such that the temperature of the vapour exiting the device through the inhalation outlet is substantially lower than the temperature of the vapour generated in the chamber. The device thereby provides a means whereby a vapour generated in the chamber is substantially cooled during transport from the chamber through the mouthpiece to the user.

The present disclosure is directed to an aerosol delivery device and a holder for use with a removable substrate cartridge. In one implementation, the holder includes a main body defining a proximal end and a distal end, the main body further providing an aerosol passageway that extends through at least a portion of the main body, and a heat sink portion. At least part of the receiving chamber is located in the heat sink portion, and the heat sink portion is configured to dissipate heat from a substrate cartridge. Some implementations further include a cartridge retention assembly and a sliding assembly. The sliding assembly is configured to slide relative to the main body to and from at least a loading position, wherein the cartridge retention assembly is configured to receive a substrate cartridge, and a use position, wherein the cartridge retention assembly is configured to retain a substrate cartridge.

A vaporizing assembly for an aerosol generating system includes a sheet heating element and a delivery device configured to deliver a liquid aerosol-forming substrate from a liquid storing portion to the sheet heating element. The sheet heating element is spaced apart from the delivery device and is configured to heat the delivered liquid aerosol forming substrate.
