At least part of the battery, the puff detector, the control electronics and/or the atomizer is mounted on an elongate insert permitting lateral access and fitting into the housing sleeve via one of the ends of the housing sleeve.

A heating element including a dense substrate and a heating film is disclosed. The dense substrate includes a first surface and a second surface opposite to the first surface. A plurality of micro-pores are arranged in the dense substrate. The micro-pores are through holes, and each of the micro-pores is configured to guide an aerosol-forming medium to the first surface. The heating film is formed on the first surface. A ratio of a thickness of the dense substrate to a pore size of the micro-pore is in a range of 20:1-3:1.

A vaporization top base in communication with a liquid storage cavity of a vaporizer includes: a top base body having a top wall and a side wall surrounding the top wall, the top wall and the side wall encircling to form a vaporization cavity that is independent of the liquid storage cavity and provided with an opening on one end; and at least two liquid feeding channels provided on the top wall, each of the at least two liquid feeding channels being in communication between the liquid storage cavity and the vaporization cavity. A first corner that is arranged close to a central axis of the vaporization cavity and a second corner that is arranged away from the central axis of the vaporization cavity are arranged in each of the liquid feeding channels. The first corner is arranged upstream of the second corner in a liquid inlet direction.

An electronic vaporization device includes: a vaporization assembly; a first power supply unit; a second power supply unit; and a control unit. The vaporization assembly vaporizes an aerosol generating substrate. The first power supply unit and the second power supply unit supply power to the vaporization assembly. The control unit controls the first power supply unit and the second power supply unit to supply power to the vaporization assembly according to a temperature of the vaporization assembly.

A heating assembly for a vaporizer is disclosed. The heating assembly includes a dense substrate having a liquid absorbing surface and a vaporization surface that are arranged opposite to each other, and a heating component disposed on the liquid absorbing surface. The dense substrate further includes a plurality of vertical holes and a plurality of transverse holes, the plurality of vertical holes run through the liquid absorbing surface and the vaporization surface, and the plurality of transverse holes communicate the plurality of vertical holes to prevent bubbles from blocking liquid supplying through the plurality of transverse holes, thereby further preventing dry burning.

A user-replaceable e-liquid reservoir for dispensing e-liquid, the reservoir being inserted into, or otherwise attached to, a portable, personal e-cigarette device and engaging with an electrical or electronic pump fluid transfer system in the device, the device including: an electrical or electronic pump, being configured to transfer e-liquid from the e-liquid reservoir to an atomizing unit in the device, the pump delivering a pre-defined or variable quantity of e-liquid from the reservoir; and in which the reservoir is not user-refillable.
