Problems solved by technology

For example, problems include: poor sensory properties of formed aerosols; consumer exposure to carbon combustion by-products, such as carbon monoxide, from fuel elements; and undesired cigarette susceptibility to strong puffing conditions
As a result, the composition of the aerosol inhaled by the consumer is disadvantageously highly sensitive to the specific puffing conditions of the consumer, and thus the sensory properties of the aerosol inhaled by the consumer are detrimentally highly sensitive to the specific puffing conditions of the consumer
Intense puff conditions can result in convective heat transfer high enough to cause peak temperatures in the aerosol-generating device of the heated smoking article to be too high, leading to significant pyrolysis and even localized combustion of the aerosol-generating device

Embodiment Construction

[0096] according to figure 1 A cigarette-like smoking article 2 of a first preferred embodiment of the invention is shown comprising a combustible heat source 4, an aerosol-generating substrate 6, an elongated expansion chamber 8 and a mouthpiece 10 arranged in an adjoining coaxial manner, which is formed by a low air permeability The wrapping material of permanent cigarette paper 12 is wrapped.

[0097] The combustible heat source 4 is a pyrolyzed porous carbon based heat source. The combustible heat source 4 is cylindrical and includes a central airflow channel 16 extending longitudinally through the combustible heat source 4 . A substantially gas impermeable iron oxide refractory coating 14 is disposed on the inner surface of the central airflow channel 16 .

[0098] The aerosol-generating substrate 6 is disposed immediately downstream of the combustible heat source 4 and comprises a cylindrical rod of homogeneous tobacco material 18 comprising glycerin as an aerosol for...

Abstract

A smoking article (2)(30) comprises: a combustible heat source (4); an aerosol-generating substrate (6) downstream of the combustible heat source (4); and a heat-conducting element (22) around and in contact with a rear portion (4b) of the combustible heat source (4) and an adjacent front portion (6a) of the aerosol-generating substrate (6). The aerosol-generating substrate (6) extends at least about 3 mm downstream beyond the heat-conducting element (22).

Description

Background technique [0001] A number of smoking articles have been proposed in the art in which the tobacco is heated rather than combusted. The purpose of such heated smoking articles is to reduce known noxious smoke constituents produced in conventional cigarettes as a result of tobacco combustion and pyrolytic degradation. Typically in such heated smoking articles, an aerosol is generated by transferring heat from a combustible fuel element or heat source to a physically separate aerosol-forming material, which may be located within the fuel element, around the fuel element, or on downstream of the fuel element. During smoking, volatile compounds are released from the aerosol-forming material by heat transfer from the fuel element and become entrained in the air drawn through the smoking article. When the released compounds cool, they condense to form an aerosol that is inhaled by consumers. [0002] For example, US-A-4,714,082 discloses a smoking article comprising: a h...
