STICK HEATING DEVICE AND METHOD OF ITS OPERATION Russian patent published in 2024 - IPC A24F40/46 

FIELD: smoking accessories.

SUBSTANCE: invention relates to designs of electric heaters of electrically driven smoking devices. This is achieved due to the fact that in the stick heating device, comprising a housing, inside which there are two heaters, a receiving sleeve, a tube, an air flow laminarizer, tube located inside the housing directly contacts the outer surface of the heaters and is made on the outside with a helical spiral, which provides an increase in the speed of air movement along the outer surface of the heaters, wherein one of heaters is located between receiving sleeve and said tube, and the other heater is adjacent to the air flow laminarizer, providing uniform air outflow over the stick end area and equalizing the temperature of the air leaving the laminarizer along the stick end area, note here that heater arranged between intake sleeve and tube with outer helical spiral is circular or composed of ring parts.

EFFECT: increasing energy efficiency of stick heating in electrically driven smoking device to temperature at which nicotine and/or ether substances are released.
