HEATING SPRAY CORE AND ELECTRONIC SPRAY DEVICE Russian patent published in 2024 - IPC A24F40/40 

FIELD: spray device.

SUBSTANCE: heating spray core and electronic spray device. The heating spray core includes a top cover, a base, liquid-conductive cotton and a heating element, which are sequentially arranged between the top cover and the base, a cotton pressing member configured to press the liquid-conductive cotton and provided on the top cover or between the top cover and the liquid-conductive cotton. The cotton pressing member includes at least one pressing strip adjacent to an upper surface of the liquid-conductive cotton, and the adjacent surface of the pressing strip that is adjacent to the liquid-conductive cotton forms a planar structure. The base is provided with an air inlet, and said cotton pressing member is provided with a liquid inlet. The electronic spray device includes a housing, a heating spray core, and a liquid storage chamber located between the spray housing and the heating spray core.

EFFECT: providing the cotton pressing member, the liquid-conductive cotton is subjected to uniform stress, the liquid-conductive gaps in the cotton pressing member are stable in size, and the liquid-conductive cotton has good liquid-locking ability, thereby preventing leakage and dripping of spray liquid, making the core difficult to burn, optimized spray effect and improved taste/aroma when spraying.
