The micro pump may be configured to deliver a particular amount of liquid aerosol-forming substrate to the internal passage based on the micro pump performing an individual pump cycle.

An aerosol generating device includes a heating element of which inner surface have different portions having different structures such that the portions of the heating element may heat corresponding areas of an aerosol generating article which is inserted in the aerosol generating device at different temperatures, thereby providing a good quality of aerosol to the user.

A vaporiser insert for an electronic cigarette product comprises at least one electrical vaporiser for vaporising fluid supplied to the vaporiser and for supplying the vaporised fluid to an airflow, a main part having a lateral face which surrounds an airflow duct through which the airflow can flow, at least one fluid opening for supplying vaporisable fluid from the outside into the vaporiser insert and to the vaporiser being arranged on the lateral face of the main part. The vaporiser insert comprises a support for retaining the vaporiser, and the support comprises a passage opening that corresponds to the fluid opening in order to supply fluid to the vaporiser.

The present disclosure provides an air heater. The air heater comprises: a direct heat generating portion configured to be heated by an electric current supplied from outside; an indirect heat generating portion configured to be heated by conductive heat, which is supplied by physical contact with the heated direct heat generating portion, and configured to heat air coming in through an inlet opening formed on one side while the air is passing through an outlet opening formed on the other side; and a housing made of an insulating material that provides a space where the direct heat generating portion and the indirect heat generating portion are placed, and that comprises an air inlet on one side through which the air is drawn in from outside and an air vent on the other side through which the air is released.

A handheld evaporation apparatus having an evaporating heating element and a housing that encases the evaporating heating element. The evaporating heating element is adapted to achieve a temperature ranging from 250 to 2000 degrees Fahrenheit by heating and differential material composition. The housing includes a first end having an opening that allows heated air provided by the evaporating heating element to exit out through the first end. The housing further includes one or more air ducts on an outer surface of the housing, where the one or more air ducts allow ambient air outside the housing to enter into the housing and flow past the evaporating heating element so as to be heated by the evaporating heating element. In one example, the housing's first end has a semi-ovoid shape that presses against and seals a hemispherical-shaped case. In another example, the housing's first end includes an elastic band that surrounds the opening and presses against the inner surface of the bowl to create a substantially airtight seal.

An atomizing module of an evaporator, the module including: an end cover; a seal ring; a meshed heating disc; an e-liquid conducting cotton including a surface; and a support. The e-liquid conducting cotton is loaded on the support. The meshed heating disc is disposed on the surface of the e-liquid conducting cotton. The meshed heating disc is made of silica-glass material prepared by consolidation of glassy nanoparticles. The end cover is embedded in the support, which facilitates the cooperation of the meshed heating disc and the e-liquid conducting cotton. The seal ring is disposed on the end cover.

A method of manufacturing a gas heater heating element including a support and channel structure with a plurality of channels formed in the monolith includes shaping an electric heating element and at least partially coating the electric heating element with at least one coating material. The at least partially coated electric heating element is positioned in a mold for producing the monolith. The monolith is produced and surrounds the at least partially coated electric heating element. The coating material of the at least partially coated electric heating element is removed. The gas heater heating element includes at least one electric heating element in the monolith and the electric heating element is guided in the plurality of channels of the support. Heat within the plurality of channels is configured to be transferred by the electric heating element to a gas flowing through the plurality of channels to heat the gas.

The present invention relates to a heater assembly for an aerosol generating device. The heater assembly includes a tubular heating chamber and a flexible thin film heater comprising a heating element track supported on a surface of a flexible electrically insulating backing film; wherein the flexible thin film heater is wrapped around an outer surface of the heating chamber with the backing film toward the heating chamber. The invention further includes a temperature sensor comprising a temperature sensing element configured to sense a local temperature, wherein the temperature sensing element is positioned so as to overlap with a portion of heating element track. Because the temperature sensing element overlaps with a portion of the heating element track, the temperature sensor provides a more accurate reading of the temperature of the heating element itself.

A device for emanating materials in the environment, preferably by heat evaporation, including: a supply for materials; an emitter of materials, for emitting the materials from the supply to surrounding environment, by application of power from a power supply according to an operation mode; an operation mode adjusting mechanism for adjusting the operation mode of the emitter, by controlling the power delivered to the emitter according to a determined transfer function. The transfer function is modular, so that it can be changed or completely replaced while keeping at least partially the adjusting mechanism in the device.
