FIELD: liquid atomisation or spraying devices.
SUBSTANCE: present invention provides a spray core, which includes a heating unit and a liquid transfer unit made of porous material and configured to absorb and transfer liquid. Liquid transfer unit comprises air guide part and base connected to air guide part and surrounding it. Gap between the air guide part and the base forms an air flow chamber. Liquid transfer unit is provided with an air inlet communicating with the air flow chamber, an air outlet communicating with the air flow chamber, and liquid inlet part for contact with liquid. Heating unit includes a heating part, which generates heat when power is supplied to it, and part of electrical connection for transfer of currents to heating part. Heating part is located on the inner wall of the air flow chamber and is in contact with the liquid transfer unit.
EFFECT: due to the fact that the air flow chamber of the spraying core is located in the liquid transfer unit made of porous material, and heating part of heating unit is located in chamber for air flow, volume, flow rate and air flow path are mainly determined by the design of the liquid transfer unit and do not depend on other parts and ratio of parts during assembly, therefore, consistency of the spraying effect is guaranteed.
