The invention relates to an evaporator unit for an inhaler, in particular an electronic cigarette product, comprising an electrically operable heating body, in particular a flat heating body, which has an inlet side and an outlet side, and a plurality of microchannels, each of which extends from the inlet side to the outlet side through the heating body. The heating body is designed to evaporate liquid being transferred through the microchannels by applying a heating voltage. A porous and/or capillary wick structure is arranged on the inlet side of the heating body, said wick structure being fluidically connected or connectable to a liquid store. The wick structure has a shaft which extends through a passage opening of the support, and a collar, which is arranged between the support and the heating body, wherein the diameter of the collar is greater than the diameter of the passage opening of the support.

An aerosol generating device which is capable of generating an aerosol at an appropriate timing includes: a power source which supplies power in order to atomize an aerosol source and/or heat a flavor source; a sensor which outputs a measurement value for controlling the power supplied; and a controller which controls the power supplied on the basis of the measurement value. The controller controls a power supply amount from the power source to be a first value when the measured value is equal to or larger than a first threshold and smaller than a second threshold larger than the first threshold, and the power supply amount to be larger than the first value when the measured value is equal to or larger than the second threshold.

This disclosure relates generally to vaporizing devices having short-circuit and leak proof capabilities. Specifically, embodiments of the present disclosure provide vaporizing devices including an atomizer wrapped with a non-woven wick and received by a distal cavity in a center post. The non-woven wick is in fluid communication with a reservoir, placing the atomizer also in fluid communication with the reservoir. Fluid travels from the reservoir, through the wick, to the atomizer to be atomized, and vaporized fluid can be pulled proximally out of the vaporizing device. A clearance of approximately 1.0 to 2.5 mm separates a top surface of the atomizer from a top surface of the distal cavity. The vaporizing devices additionally include an electrode (e.g., an anode) in electrical communication with an anode wire of the atomizer. An insulating sleeve maintains the position of the anode wire against the electrode, allowing for good electrical conductivity and communication.
