A heater system for a non-combustible aerosol-generating device includes a heater element and a fuse element. The heater element has a heating region, a first terminal and a second terminal. The fuse element is electrically connected between the first terminal and the second terminal in parallel with the heater element. The fuse element has a region configured to induce a localized hot spot to cause the fuse element to open circuit in response to power applied between the first terminal and the second terminal.

A vaporizer, cooperating with a main unit to implement vaporization, includes: a shell in which an air outlet channel is formed; a vaporization assembly having a vaporization channel in communication with the air outlet channel; and an electrode assembly mated with the vaporization assembly and including an insulating member, a first electrode, and a second electrode, the insulating member being at least partially sleeved on the vaporization assembly, the first electrode being sleeved in the insulating member, and the second electrode being sleeved outside the insulating member. An air through channel in communication with the vaporization channel is defined and formed between the first electrode and the insulating member.

The present application discloses a heater and a smoking device including the heater. The heater includes: a base having a surface; an infrared electrothermal coating, being disposed on the surface of the base; a conductive module, comprising a first conductive portion and a second conductive portion arranged on the base, both the first conductive portion and the second conductive portion being electrically connected with the infrared electrothermal coating; a flexible printed circuit board, comprising a flexible substrate and a first electrode and a second electrode formed on the flexible substrate; the flexible substrate being fixed on the surface of the base so that the first electrode is electrically connected with the first conductive portion, and the second electrode is electrically connected with the second conductive portion.

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.

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.

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.
