Embodiment Construction

[0049] Typically, the invention does not require a primary unit, in which case the secondary unit may be a self-contained unit connectable to an existing external power supply. However, as noted above, in one embodiment the electrically heated smoking system of the present invention comprises a primary unit and one or more secondary units capable of receiving smoking articles. The main unit includes the main power supply and electronic circuits. The secondary unit includes a secondary power supply, electronic circuitry and at least one heating element. In the charging mode, the primary power source in the primary unit may be used to charge the secondary power source in the secondary unit, and in the preheat mode, the primary power source in the primary unit is used to initially heat the aerosol-forming substrate of the smoking article . Once the temperature of the aerosol-forming substrate has risen to the operating temperature, a secondary power supply in the secondary unit...

Abstract

There is provided an electrically heated smoking system comprising a secondary unit capable of receiving a smoking article having an aerosol-forming substrate. The secondary unit comprises at least one heating element and an interface for connection to a primary power supply for supplying electrical power to the at least one heating element during a pre-heating mode, to increase the temperature of the aerosol-forming substrate to an operating temperature. The secondary unit further comprises a secondary power supply arranged to supply electrical power to the at least one heating element during a smoking mode, to maintain the temperature of the aerosol-forming substrate at substantially the operating temperature. The secondary unit further comprises secondary circuitry. The electrically heated smoking system may optionally include a primary unit comprising the primary power supply and primary circuitry. By dividing the power supply between the primary unit and the secondary unit, the secondary unit can be made smaller and more convenient for the user.

Description

technical field [0001] The present invention relates to an electrically heated smoking system having a unit for receiving smoking articles, wherein the unit comprises a secondary power supply and the unit is connectable to a main power supply. Background technique [0002] Several prior art documents disclose electrically operated smoking systems which have several advantages. One advantage is that these electrically operated smoking systems significantly reduce sidestream smoke while at the same time allowing the smoker to selectively activate the smoking system during smoking. Prior art electrically operated smoking systems typically comprise a housing for receiving a smoking article, a heating element for generating aerosol, a power supply and the necessary electronic circuitry. The circuit may be activated manually or by inserting a cigarette into the housing, and the circuit may limit operation of the heating element to a predetermined period of time. [0003] However...
