An aerosol-generating system includes a reservoir containing an aerosol-forming substrate. The system also includes first and second heating elements and first and second liquid transfer elements. The first and second heating elements are spaced apart from the reservoir. The first and second liquid transfer elements are configured to deliver aerosol-forming substrate from the reservoir to the heating elements. The first liquid transfer element has first and second end portions and a portion between the first and second end portions at the first heating element. The second liquid transfer element has first and second end portions and a portion between the first and second end portions at the second heating element. The portion of the first liquid transfer element at the first heating element may extend in a first direction. The portion of the second liquid transfer element at the second heating element may extend in a second direction.

A reservoir refill system for an electronic vaping device includes a refill container and a reservoir. The refill container contains a pre-vapor formulation. The refill container includes a body, an opening in the body, and a first interlocking ring including at least one groove or at least one protrusion therein. The reservoir is configured to contain a pre-vapor formulation and includes a reservoir body, an opening in the reservoir body, and a second interlocking ring including at least one groove or at least one protrusion therein at an opening of the reservoir. The first interlocking ring is configured to mate with the second interlocking ring so as to release the pre-vapor formulation from the refill container to the reservoir.

The invention relates to an atomizer for an electronic cigarette and an electronic cigarette with a new connection structure scheme. The solution adopted in the present invention is: an atomizer for an electronic cigarette, comprising an oil storage pipe, a ventilation pipe, an atomization assembly and an electrical connection seat. The ventilation pipe is arranged in the oil storage pipe. The atomizer comprises a limiting stepped column and a protrusion protruding from an outer side surface of the ventilation pipe. The stepped column and the protrusion are arranged at one end of the ventilation pipe and define a groove at the outer side surface of the ventilation pipe. One end of the oil storage pipe is radially provided with a flange and one end of the electrical connection seat is radially provided with an edgefold. The flange and the edgefold are sleeved and fixed in the groove.

A heating body includes: a substrate; a heating layer arranged on the substrate; and a protruding structure layer arranged on the heating layer. The protruding structure layer includes a plurality of protruding units arranged on the heating layer at intervals or the protruding structure layer has a grid shape. In an embodiment, the heating body further includes: an insulating and heat-conducting layer arranged between the protruding structure layer and the heating layer.

A heating assembly includes a closure member, an atomizing core, and a sealing member sleeved on the atomizing core and clamped between the atomizing core and the closure member. The closure member includes a main body portion, e-liquid passages and an air passage defined on the main body portion and being independent of each other, an accommodation cavity disposed below the e-liquid passages and in communication with the e-liquid passages, and a part of an atomizing cavity disposed below the accommodation cavity. The atomizing core includes a seepage surface in communication with the e-liquid passages, and an atomizing surface in communication with the atomizing cavity. The sealing member includes a packing portion closely attached to an interior of the accommodation portion. The packing portion includes a packing wall and a covering portion.
