An aerosol generating article includes: a first portion comprising an aerosol generating material; a second portion comprising a tobacco material including a moisturizing agent; a third portion configured to cool airflow that has passed through the first portion and the second portion; a fourth portion comprising a filter material; and a wrapper that surrounds the first portion, the second portion, the third portion, wherein the second portion includes the moisturizing agent in an amount of 10 wt % or less based on a total weight of the tobacco material such that heat conductivity in the second portion is improved.

The present invention relates to a vaping article comprising an aerosol-generating zone, a zone for cooling the aerosol comprising a paper in the shape of a hollow tube, this paper comprising a fibrous substrate, and optionally a filtering zone,
characterized in that the zone for cooling the aerosol is functionalized by a plant extract and an aerosol-generating agent.

A smoking article wrapper includes a non-perforated air permeable base paper having a naturally high porosity of 40-80 cm.sup.3/min air passing through a sample of 1 cm.sup.2 of this base paper at an applied pressure difference of 1 kPa, wherein the smoking article wrapper has at least one embossed surface area and at least one non-embossed surface area. The air permeability of the smoking article wrapper is such that it provides a mean volumetric flow rate of ≥40 cm.sup.3/min air passing through a sample of 1 cm.sup.2 of this smoking article wrapper at an applied pressure difference of 1 kPa. The embossed area includes an embossing having a depth of ≥16 μm. A smoking article including the smoking article wrapper and respective methods to produce such a smoking article wrapper and a smoking article are also provided.

A heat-not-burn cigarette includes a shell, a driving assembly, and a locking mechanism. The shell is provided with an opening and an accommodation cavity. The opening communicates the accommodation cavity with an outside world. The locking mechanism is provided in the accommodation cavity. The driving assembly is transmissively connected to the locking mechanism to drive the locking mechanism to form a smaller clamping ring and a larger clamping ring. The locking mechanism includes a bearing assembly and at least one transmission assembly. The bearing assembly is adjustably connected to the transmission assembly, and the transmission assembly is connected to the driving assembly, so as to provide preset tracks for the bearing assembly. The bearing assembly expands or contracts along the preset tracks, such that the bearing assembly is adjustably attached to a peripheral side of a cigarette body.
