Definitions
- the present invention relates to a smoking substitute system and particularly, although not exclusively, to a smoking substitute system comprising a smoking substitute device and a rechargeable power source.
- Conventional combustible smoking articles such as cigarettes, typically comprise a cylindrical rod of tobacco comprising shreds of tobacco which is surrounded by a wrapper, and usually also a cylindrical filter axially aligned in an abutting relationship with the wrapped tobacco rod.
- the filter typically comprises a filtration material which is circumscribed by a plug wrap.
- the wrapped tobacco rod and the filter are joined together by a wrapped band of tipping paper that circumscribes the entire length of the filter and an adjacent portion of the wrapped tobacco rod.
- a conventional cigarette of this type is used by lighting the end opposite to the filter, and burning the tobacco rod. The smoker receives mainstream smoke into their mouth by drawing on the mouth end or filter end of the cigarette.
- Such smoking substitute systems can form part of nicotine replacement therapies aimed at people who wish to stop smoking and overcome a dependence on nicotine.
- Smoking substitute systems include electronic systems that permit a user to simulate the act of smoking by producing an aerosol (also referred to as a“vapour”) that is drawn into the lungs through the mouth (inhaled) and then exhaled.
- aerosol also referred to as a“vapour”
- the inhaled aerosol typically bears nicotine and/or flavourings without, or with fewer of, the odour and health risks associated with traditional smoking.
- smoking substitute systems are intended to provide a substitute for the rituals of smoking, whilst providing the user with a similar experience and satisfaction to those experienced with traditional smoking and with combustible tobacco products.
- Some smoking substitute systems use smoking substitute articles (also referred to as a“consumables”) that are designed to resemble a traditional cigarette and are cylindrical in form with a mouthpiece at one end.
- a“consumables” also referred to as a“consumables”
- the popularity and use of smoking substitute systems has grown rapidly in the past few years.
- HT Heated Tobacco
- HNB Heat not burn
- the tobacco may be leaf tobacco or reconstituted tobacco.
- the vapour may contain nicotine and/or flavourings.
- the intention is that the tobacco is heated but not burned, i.e. the tobacco does not undergo combustion.
- a typical HT smoking substitute system may include a device and a consumable.
- the consumable may include the tobacco material.
- the device and consumable may be configured to be physically coupled together.
- heat may be imparted to the tobacco material by a heating element of the device, wherein airflow through the tobacco material causes components in the tobacco material to be released as vapour.
- a vapour may also be formed from a carrier in the tobacco material (this carrier may for example include propylene glycol and/or vegetable glycerine) and additionally volatile compounds released from the tobacco.
- the released vapour may be entrained in the airflow drawn through the tobacco.
- the vapour passes through the consumable (entrained in the airflow) from the location of vaporisation to an outlet of the consumable (e.g. a mouthpiece), the vapour cools and condenses to form an aerosol for inhalation by the user.
- the aerosol will normally contain the volatile compounds.
- HT smoking substitute systems heating as opposed to burning the tobacco material is believed to cause fewer, or smaller quantities, of the more harmful compounds ordinarily produced during smoking. Consequently, the HT approach may reduce the odour and/or health risks that can arise through the burning, combustion and pyrolytic degradation of tobacco.

- the porous wick conveys e-liquid from the tank 327 to the heating element.
- the heating element is a heating filament that is helically wound around a portion of the porous wick, such that when the heating element is heated (e.g. by the action of electrical current passing through the heating element), heat is transferred from the heating element to the e-liquid conveyed by the wick.
- This transfer of heat vaporises the e-liquid and the resultant vapour is entrained in an airflow passing through the consumable 302 (i.e. driven by a user drawing on a downstream end 318 of the consumable 302). Between the vaporisation point at the coil and the downstream end 318 (i.e. the mouth end), the vapour condenses into an aerosol, and is subsequently inhaled by the user.
- the device 301 comprises a power source in the form of a rechargeable battery (not shown) and a connector in the form of a USB port (not shown).
- the device 301 further comprises controller (also not shown).
- the rechargeable battery, connector and controller are similar (and operate in a similar manner) to the corresponding components of the embodiment described above with respect to Figure 1 A to 1 E.
- the consumable 302 includes a pair of heater electrical contacts 328 disposed on a device-facing end surface of the consumable 302.
- the heater electrical contacts 328 are electrically connected to the heater 304 in the consumable 302, such that a voltage applied across the heater electrical contacts 328 generally corresponds to a voltage applied across the resistive heating element of the heater 304.
- the heater electrical contacts 328 are brought into electrical contact with corresponding device electrical contacts (not shown) on the device 301 .
- the device electrical contacts are electrically connected (directly or indirectly) to the rechargeable battery.
- the controller may thus be configured to control the voltage applied across the device electrical contacts from the rechargeable battery. By controlling the voltage applied across the device electrical contacts, the voltage applied to the heater 304 is correspondingly controlled.
- the device 301 includes an output means (forming part of the Ul of the system 300) in the form of a single light-emitting diode (“LED”) 31 1 .
- the LED 31 1 is operatively connected to the controller, such that controller can control the illumination of the LED 31 1 .
- the controller is configured to illuminate the LED when then the heater 304 is active.
- the device 301 also includes an input means in the form of a puff sensor (not shown).
- the puff sensor is the same as that described above with respect to the embodiment shown in Figure 1 A to 1 E.
