FIELD: liquid atomisation or spraying devices.
SUBSTANCE: present invention relates to an evaporative cartridge. Evaporation cartridge is characterized by the fact that it includes a liquid storage chamber, an independent air guide element, communicating the liquid storage chamber with the atmosphere, and an evaporation core, wherein the evaporation core includes a heating element and a liquid-conducting element, wherein independent air guide element is used for conducting gas without conducting liquid into liquid storage chamber to evaporation core, when independent air guide element is in contact with liquid, under action of capillary force it is impregnated with liquid, and through hole of independent air guide element is sealed with liquid, wherein said independent air guide element includes an independent air guide element core and at least one through hole of independent air guide element passing in axial direction through independent air guide element.
EFFECT: evaporative cartridge accurately controls vacuum in the liquid storage chamber, uniformly removing the liquid from the liquid storage chamber, maintaining the liquid volume on the liquid-conducting element of the evaporative core, thereby stabilizing the spraying and reducing the risk of liquid leakage.
