The curing needle head is externally plated with a non-stick coating which is a polytetrafluoroethylene (PTFE) coating or a PTFE non-stick nano coating. The curing needle head is further provided with a fixed support and a ceramic base, the ceramic base is secured into the fixed support, and the curing needle head is fixedly inserted into the ceramic base. The E-cigarette is provided with the aforesaid circumferentially heating type curing needle.

An aerosol generation device may include a case: a carrier coupled to the case; and a plurality of terminals coupled to the carrier and including one end in contact with a power source external to the case and the other end extending and protruding from the one end to an inside of the case.

A vaporizer apparatus includes a pump housing, a main housing containing an evacuation chamber, and an operation unit attached to the main housing. The operation unit selectively seals the evacuation chamber off from communication with an air inlet. One or more pumps in the pump housing is/are operable to generate a vacuum in the evacuation chamber. A mouthpiece is attached to the main housing, and may be selectively placed in communication with the evacuation chamber. When oil is placed in the evacuation chamber and the operation unit is operated, the evacuation chamber is temporarily sealed off from the inlet, creating a vacuum sealed chamber connected with the pump(s). Then, the pump(s) is/are activated to reduce pressure in the evacuation chamber, and the oil is vaporized at an ambient temperature without requiring a heater. When the operation unit is released, the evacuation chamber is emptied via the mouthpiece.

An induction heating assembly for a vapour generating device includes a rechargeable power source and an induction coil. The induction coil is arranged to heat, in use, a susceptor and is also arranged to receive, in use, an electromagnetic field generated by an external source to charge the power source.

The present application relates to an electronic vaporizer, an electronic vaporizer device body, and an electronic vaporizer device. An electronic vaporizer is used in combination with an electronic vaporizer device body, wherein the electronic vaporizer device body at least comprises a power supply, a first pin and a second pin; and the electronic vaporizer comprises: a storage compartment, storing a vaporizable substance; and a heating circuit, comprising: a heating component, configured for heating; and a first and second contact pad, wherein the heating circuit changes a voltage or current between the first pin and the second pin after the first and second contact pad being electrically contacting with the first and second pin respectively; and after detecting the voltage or the current changes, the electronic vaporizer device body controls the power supply to supply power to the heating component via the first and second contact pad.

The present disclosure discloses a power supply assembly for an electronic cigarette and an electronic cigarette. The power supply assembly includes a main body and a trigger switch. The main body may be provided with an accommodation space for accommodating circuit components. The trigger switch may be mounted inside the accommodation space by a seal. A first channel and an air flow sensing duct may be connected to the trigger switch. The first channel may include a first end and a second end that are arranged oppositely. The first end may communicate with the air suction pathway of an atomizer of the electronic cigarette, and the air flow sensing duct may communicate with a lateral wall of the first channel close to the first end.

The disclosure relates to an electronic atomizing device and an atomizer and a liquid injection structure thereof. The liquid injection structure includes an outer pipe provided with an exhaust port and a liquid injection assembly including a sleeve pipe disposed in the outer pipe and a liquid injection pipe disposed in the sleeve pipe. The liquid injection pipe is provided with a liquid injection port, and is axially movable relative to the sleeve pipe between a first position where the sleeve pipe seals the liquid injection port and a second position where the seal of the liquid injection port by the sleeve pipe is released. The sleeve pipe is axially movable relative to the outer pipe between a third position where the sleeve pipe seals the exhaust port and a fourth position where the seal of the exhaust port by the sleeve pipe is released.

A heater for use in an aerosol generating device is disclosed. The heater includes a heating element comprising a coil. The coil has at least two coiled regions and one non-coiled region. The heater includes a pair of wicks arranged to feed e-liquid to the heating element from different directions. A device for generating an inhalable medium including a heater for volatilizing liquid is also disclosed.

An electrically operable aerosol-generating system is provided, including a charging device including a primary power source; and an elongated aerosol-generating device including a secondary power source and having a proximal end, a distal end, and a body extending between the proximal end and the distal end, a user operable button being disposed on the body between the proximal end and the distal end, the system having a first engagement state in which the aerosol-generating device is engaged with the charging device and a second engagement state in which the aerosol-generating device is not engaged with the charging device, such that, when the system is configured in the first engagement state, at least a first side-portion of the body faces the charging device, and at least a second side-portion of the body extending between the proximal end and the distal end faces away from the charging device and is exposed.
