A diffuser assembly is disclosed. The assembly comprises a tubular chamber having a plurality of grooves spaced apart on an interior wall of the tubular chamber. A circumferential compression fit diffuser disc is retained in a groove from the plurality of grooves, wherein the circumferential compression fit diffuser disc is retained by a spring pressure resisting force of the circumferential compression fit diffuser disc. A diffuser and an adjustable vaporization chamber are also disclosed.

A cartridge for use in a smoking device for vaporization including a first area for including a smokeable material, a second area for including a vapor-forming material, and a perforation allowing vapor to exit the cartridge upon heating the cartridge.

A method for producing a vaporisable material comprising plant fibres for use in a vapour generating device which generates a vapour by heating the vaporisable material is disclosed. The method comprises reducing the particle size of the plant fibres to less than 1.5 mm and mixing plant fibres of at least two ranges of particle size. The invention also relates to vaporisable material for use in a vapour generating device obtainable by the method.

Disclosed is a vaporizable substance application tool having an integrated ideal temperature indicator. In one embodiment, an apparatus includes an applicator, a thermocouple, and a temperature indicator. The applicator is positioned on a first end of the apparatus to apply a vaporizable substance onto a heatable surface. The thermocouple is positioned on a second end of the apparatus. The temperature indicator is positioned between the applicator and the thermocouple. In addition, the temperature indicator of the apparatus visually indicates different temperature states. In a first state, a background of the temperature indicator illuminates in a first color when the temperature is below an ideal range. In a second state, the background of the temperature indicator illuminates in a second color when the temperature is within the ideal range. In a third state, the background of the temperature indicator illuminates in a third color when the temperature exceeds the ideal range.

Pellet substrates configured for use with a vapor delivery device to vaporize and deliver an aerosol to a user include a semi-porous base material formed of activated alumina pellets, activated carbon pellets, hulled millet grains that have a generally rounded shape or cellulose paper that has a generally disc shape. The pellet substrates are formed by mixing the base material with a liquid solution of an aerosol former and at least one of a tobacco extract mixture and a tobacco powder blend until the liquid solution is absorbed onto the exposed surfaces of the base material with or without drying by applying heat. The base material may be coated with a liquid hydrocolloid gum solution, namely a water soluble gum, such as sodium carboxymethyl cellulose, and distilled water to reduce fracturing, cracking, chipping and dusting of the pellet substrates.

A vaporisable material for use in a vapour-generating device comprising tobacco having a moisture content of from about 3 to 5 wt %, and further comprising a humectant in an amount of at least 20 wt % is disclosed. The invention also relates to use of the vaporisable material in a vapour-generating device, and to a sealed package containing the vaporisable material and a device containing the sealed package of vaporisable material.

A system for generating and inhaling vapor of herbs includes a container, a base, a mouth, and an upper surface. An aperture in the surface displaced from a lip of the mouth. The container shown partially filled with water, and a diffuser positioned upon the water. The region within the container above the diffuser defines a vapor chamber. A diagonally-oriented tube includes upper and lower end secured within the aperture. Herbs are placed in an upper end of an herb-burning bowl and a lower end of the bowl having a filter limiting debris from entering the water. An inhalation cylinder having upper end attachable within an open mouth. A vacuum pump includes vacuum input from cylinder and positive pressure output about a level of the vacuum input. The pump providing pressure from bottom to top of the inhalation cylinder and the water surface diffuser to the mouth.

The present disclosure is directed to an aerosol delivery device for use with a removable and replaceable cartridge and including actuatable ignitor contacts. The device includes a holder defining a receiving chamber configured to receive the cartridge, the cartridge comprising an ignitable heat source and a substrate portion comprising an aerosol precursor composition. The device further includes a first aerosol passageway, a mouthpiece defining a second aerosol passageway, and a power source disposed therein. The actuatable ignitor contacts are configured to engage with the ignitable heat source when the removable cartridge is secured within the receiving chamber and are movable between a first position spaced apart from the ignitable heat source and a second position contacting the ignitable heat source. The device may also include a dual-purpose actuator assembly coupled to the holder and configured to ignite the ignitable heat source and eject the removable cartridge.
