Problems solved by technology

[0003] A problem with this proposed smoking system is that tobacco smoke tends to condense on the interior walls of the smoking system
This is undesirable as condensation that builds up on the interior walls of the smoking system can lead to reduced performance

Embodiment Construction

[0063] figure 1 A smoking article 101 is shown received in an electrically heated smoking system 103 according to a first embodiment of the invention. In this embodiment, the smoking article 101 has an elongated cylindrical shape and comprises an aerosol-forming substrate 105, a filter rod 107, the aerosol-forming substrate 105 and the filter rod 107 according to Arranged sequentially and aligned coaxially. Both parts 105 and 107 are wrapped by outer wrapping paper 109 . In this embodiment, the aerosol-forming substrate 105 is in the form of a cylindrical plug of solid substrate. The length l of the bung is substantially parallel to the length of the smoking article and also substantially parallel to the direction of airflow (not shown) in the electrically heated smoking system when a user smokes on the smoking article. The perimeter of the plug is substantially perpendicular to the length. The filter rod 107 is located at the downstream end of the smoking article 101, and...

Abstract

An electrically heated smoking system (103, 203) for receiving an aerosol-forming substrate (105, 205) is provided. The electrically heated smoking system includes a heater for heating the substrate to form an aerosol, and the heater includes a heating element (113, 213, 214). The electrically heated smoking system (103, 203) and the heating element (113, 213, 214) are arranged such that when the aerosol-forming substrate (105, 205) is received in the electrically heated smoking system, the heating element ( 113 , 213 , 214 ) extend a distance only partially along the length of the aerosol-forming substrate, and the heating element is positioned proximate to the downstream end of the aerosol-forming substrate.

Description

technical field [0001] The present invention relates to an electrically heated smoking system comprising a heater for heating an aerosol-forming substrate. Background technique [0002] EP-A-0358002 discloses a smoking system comprising a cigarette having a resistive heating element for heating tobacco material in the cigarette. The cigarette has an electrical connection plug for connection to a reusable handheld controller. The handheld controller includes a battery and a current control circuit that controls the supply of power to a resistive heating element in the cigarette. [0003] One problem with this proposed smoking system is that tobacco smoke tends to condense on the inner walls of the smoking system. This is undesirable because condensation that builds up on the interior walls of the smoking system can lead to reduced performance. [0004] It would therefore be advantageous to provide an electrically heated smoking system which, in use, minimizes the risk of c...
