Cartridges for vaporizer devices are provided. In one exemplary embodiment, the cartridge can include a reservoir configured to contain a plurality of encapsulated particles and an airflow tube extending through the reservoir. Each of the plurality of encapsulated particles includes a core formed of a liquid vaporizable material and a coating material that forms a shell surrounding the core, in which the shells of the plurality of encapsulated particles are configured to be selectively ruptured to release the liquid vaporizable material therefrom. The airflow tube includes a wicking element that is in communication with the reservoir, in which the wicking element is configured to draw, into the airflow tube for vaporization, at least a portion of the liquid vaporizable material that is released by rupturing one or more shells of the plurality of encapsulated particles. Vaporizer devices are also provided.

A simulated cigarette having an elongated hollow cylinder and having a cavity there within, with a cylindrical wick disposed in the cavity, the wick having a radial clearance and longitudinal clearance with respect to the cavity for allowing the wick to freely slide along a longitudinal direction of the cavity. The simulated cigarette having a fan assembly disposed in the cavity adjacent wick and in an alternate embodiment having a flexible filter affixed to an end of the hollow cylinder.

An aerosol generating device defines a flow path from an air inlet to an inhalable medium outlet. The device includes a container for containing a liquid; a wick for drawing liquid from the container into the flow path, and a heating element, upstream of the wick, for heating inlet air from the air inlet to generate a flow of heated air in the flow path in use. The device is arranged such that, in use, the flow of heated air generated in use passes over the wick to volatilize the liquid to generate, in use, a flow of aerosol in the flow path. The device includes a receiving portion in the flow path, downstream of the wick, for receiving an element for modifying a property of the flow of aerosol. A device including a shield element to shield the wick from a heating element is also disclosed.
