Definitions

• the smoking of tobacco is generally considered to expose a smoker to potentially harmful substances. It is generally thought that a significant amount of the potentially harmful substances are generated through the heat caused by the burning and/or combustion of the tobacco and the constituents of the burnt tobacco in the tobacco smoke itself.
• Smoking substitute devices which may also be known as electronic nicotine delivery systems, may comprise electronic systems that permit a user to simulate the act of smoking by producing an aerosol, also referred to as a“vapour”, which is drawn into the lungs through the mouth (inhaled) and then exhaled.
• a“vapour” which is drawn into the lungs through the mouth (inhaled) and then exhaled.
• the inhaled aerosol typically bears nicotine and/or flavourings without, or with fewer of, the odour and health risks associated with traditional smoking.
• the rib extends from the outlet in a radially outward direction to an internal surface of a wall of the tank. By spanning the spacing between the wall of the tank and the outlet, the position of the outlet relative to the tank is maintained.
• Figure 1 (b) shows the main body 120 of the smoking substitute device 1 10 without the consumable 150.
• the main body 120 and the consumable 150 are configured to be physically coupled together, in this example by pushing the consumable 150 into an aperture in a top end 122 of the main body 120, such that there is an interference fit between the main body 120 and the consumable 150.
• the main body 120 and the consumable could be physically coupled together by screwing one onto the other, or through a bayonet fitting, for example.
• An optional light 126 e.g. an LED, located behind a small translucent cover, is located a bottom end 124 of the main body 120. The light 126 may be configured to illuminate when the smoking substitute device 1 10 is activated.
• the main body 120 includes a power source 128, a control unit 130, a memory 132, a wireless interface 134, an electrical interface 136, and, optionally, one or more additional components 138.
• the memory 132 is preferably includes non-volatile memory.
• the memory may include instructions which, when implemented, cause the control unit 130 to perform certain tasks or steps of a method.
• the electrical interface 136 of the main body 120 may include one or more electrical contacts.
• the electrical interface 136 may be located in, and preferably at the bottom of, the aperture in the top end 122 of the main body 120.
• the electrical interface 136 may be configured to pass electrical power from the power source 128 to (e.g. a heating device of) the consumable 150 when the smoking substitute device 110 is activated, e.g. via the electrical interface 160 of the consumable 150 (discussed below).
• the electrical interface may be configured to receive power from a charging station, when the main body 120 is not physically coupled to the consumable 150 and is instead coupled to the charging station.
• the electrical interface 136 may also be used to identify the consumable 150 from a list of known consumables.
• the additional components 138 of the main body 120 may comprise the optional light 126 discussed above.
• an interface for obtaining an identifier of the consumable may be provided.
• this interface may be, for example, an RFID reader, a barcode or QR code reader, or an electronic interface which is able to identify the consumable to the main body.
• the consumable may, therefore include any one or more of an RFID chip, a barcode or QR code, or memory within which is an identifier and which can be interrogated via the electronic interface in the main body.
• the smoking substitute device 1 10 shown in Figs. 1 and 2 shows just one example implementation of a smoking substitute device, and that other forms of smoking substitute device could be used.
• the first tank draft angle is preferably at least 0.5 degrees, preferably at least 1 .0 degrees, preferably at least 1.5 degrees, preferably at least 2.0 degrees, preferably at least 2.5 degrees, preferably at least 3.0 degrees, preferably at least 3.5 degrees.
• the first outlet draft angle is preferably not more than 3.5 degrees, preferably not more than 3.0 degrees, preferably not more than 2.5 degrees, preferably not more than 2.0 degrees, preferably not more than 1.5 degrees, preferably not more than 1.0 degrees, preferably not more than 0.5 degrees.
• the airway has an internal width of more than 2.9 mm at an upstream end of the outlet 306. Yet more specifically, the airway has an internal width of more than 3.1 mm at an upstream end of the outlet 306. Yet more specifically, the airway has an internal width of more than 3.3 mm at an upstream end of the outlet 306.
• the airway has an internal width greater than 2.0 mm at the upstream end of the outlet 306. More specifically, the airway has an internal width greater than 2.5 mm at the upstream end of the outlet 306. More specifically, the airway has an internal width greater than 3.0 mm at the upstream end of the outlet 306. More specifically, the airway has an internal width greater than 3.2 mm at the upstream end of the outlet 306. More specifically, the airway has an internal width greater than 3.4 mm at the upstream end of the outlet 306.
• the consumable 150 further comprises a tank seal 308, which seals a bottom portion of the tank 156 beneath the heating device 162.
• the tank seal 308 is connected to the heating device 162, and the tank seal 308 comprises an air inlet 164, such that air flow is permitted from outside the tank through the air inlet 164 to the heating device 162.
• first mould 402 and the second mould 404 When the first mould 402 and the second mould 404 are brought together, they define a closed cavity which has the shape of the tank 156, the mouthpiece 166 and the outlet 306.
