An electronic cigarette including an atomization assembly and a battery assembly. The atomization assembly includes a first housing; a heating wire; a limit cover; a first silicone seal sealing the limit cover; a monolayer nonwoven fabric; a multilayer nonwoven fabric; a fixed seat fixing the heating wire; an insulation ring; a joint; a silicone gasket sealing the fixed seat; a sealing seat; a first seal ring; an e-liquid injection seat; a spring; a funnel; a second seal ring sealing the funnel; a second silicone seal; a cover; and a first magnet. The battery assembly includes a third silicone seal sealing a pneumatic switch; a support plate supporting the pneumatic switch; a control plate; a position limiter limiting the control plate; a battery core; a second magnet; a third seal ring; a support supporting the control plate; a decorative plate; a second housing; and a press button.

A handheld, portable vaporizer apparatus is operable to vaporize oils, such as e-liquids, cannabis oils, or dry herbs, without heating the oils. The vaporizer apparatus includes a main housing having an oil chamber, an oil reservoir connected to the oil chamber, and an evacuation chamber connected to the oil reservoir formed therein; an operation unit; a manifold connected to the main housing; a pump; and a control unit connected to the operation unit and pump. When the operation unit is operated, the oil reservoir is isolated from the oil chamber and the bottom of the evacuation chamber is sealed thereby creating a vacuum sealed chamber having oil trapped therein and being connected with an inlet of the pump, and the control unit turns the pump on causing a pressure differential so that oil trapped in the vacuum sealed chamber vaporizes without heat and flows through the manifold and mouthpiece.

A power supply unit for an aerosol inhaler, which causes an aerosol generated from an aerosol source to pass through a flavor source, includes: a power supply dischargeable to a first load configured to heat the aerosol source and dischargeable to a second load configured to heat the flavor source; a notification unit; a processing device; a circuit board; and a conductive portion configured to electrically connect the second load and the circuit board. The processing device is configured to detect adhesion of a liquid to the second load or entry of the liquid into the conductive portion. When the adhesion or the entry is detected, the processing device executes at least one of a notification action that causes the notification unit to execute a notification and a first fail-safe action including prevention of discharging from the power supply to the second load.

A hookah includes a negative ion emitter radiating negative ions into an area around the hookah. Smokers may exhale smoke into the area of the negative ions and the negative ions react with elements in the smoke purifying the surrounding air. An example of a negative ion emitter is a plasma light.

An aerosol-generating device is provided, including a housing having a chamber configured to receive at least a portion of an aerosol-forming article; a first coil disposed at least partially around, or adjacent to, the chamber; and a second coil disposed at least partially around, or adjacent to, the chamber, the first coil being part of a first resonant circuit having a first resonant frequency and the second coil forming part of a second resonant circuit having a second resonant frequency.

An electronic cigarette and a method for adjusting the power thereof are provided. The electronic cigarette includes an atomizer and a battery device. The battery device includes a casing, and a controller and a power output module disposed inside the casing. The atomizer is detachably connected to the battery device. The casing is provided with an indication module. The controller is electrically connected to the indication module and the power output module, separately. The controller controls the indication module to alternately issue different indication signals. When the controller detects that the atomizer is connected to the battery device, the controller determines the target output power corresponding to the indication signal currently issued by the indication module according to the pre-stored correspondences between the indication signals and the output powers. When a suction signal is detected, the controller controls the power output module to output the target output power.

An electronic smoking device operable in at least two states. A switch is configured to selectively toggle the device between a first state in which a power source provides energy to a first heating element to produce a first vapor of a first flavor, and a second state in which the power source provides energy to a second heating element to produce a second vapor of a second flavor. The controller may operate the device in a most recently toggled state based on detection of the draw by a sensor. The switch may be a non-momentary switch, and may extend through an opening in a casing. An indicator assembly may include indicator lights configured to be selectively illuminated based on the device being in the first or second state. The device may be operable in a third state in which energy is provided to the first and second heating elements.

There is provided an aerosol-generating article including an aerosol-forming substrate and a plurality of electrical fuses. The plurality of electrical fuses are spaced apart from each other, each electrical fuse disposed proximate a portion of the aerosol-forming substrate. There is also provided an aerosol-generating device for the aerosol-generating article, an aerosol-generating system including the aerosol-generating article and the aerosol-generating device, and a controller for the aerosol-generating device.

There is provided an aerosol-generating system including an aerosol-generating device and a cartridge assembly, the device including a device inner housing defining a device cavity, an electrical heater, and a device outer housing; and the cartridge assembly including a cartridge assembly inner housing defining a substrate compartment, an aerosol-forming substrate positioned within the substrate compartment, and a cartridge assembly outer housing, and a portion of the cartridge assembly inner housing is configured to be received within the device cavity, and, when the portion of the cartridge assembly inner housing is received within the device cavity, at least a first part of a downstream edge of the device outer housing abuts at least a first part of an upstream edge of the cartridge assembly outer housing so that the cartridge assembly outer housing and the device outer housing form a system outer housing.
