Referring to fig. 11-12, when the electronic heating atomizer assembly 1 is applied to an electronic heating atomizer, air enters a channel of the liquid storage bin 21 when the air pressure in the liquid storage bin 21 of the device is reduced, so that air is prevented from passing through the liquid guide piece 151 of the atomizing core 15 to influence the liquid guide performance of liquid guide materials.

The function of the liquid return capillary groove 123 is to dredge excessive liquid accumulated in the ventilation capillary groove 122, and avoid that the liquid (condensate or atomized liquid extruded from the ventilation channel 1220 in special environment) blocks the ventilation capillary groove 122 to cause difficult ventilation, which affects the liquid guiding performance of the liquid guiding member 151.

When the electronic heating atomizer assembly 1 is applied to an electronic heating atomizer, when the external air pressure becomes lower in some characteristic environments such as high air or places with high altitude, the air pressure in the liquid storage bin 21 of the electronic heating atomizer is higher than the external air pressure, liquid can be extruded from the liquid storage bin 21, and can be stored in some gaps in the device such as the ventilation capillary groove 122, if the liquid is not consumed and removed, the pressure difference required for ventilation in normal use is greatly affected, and ventilation caused by blocking of the liquid is not smooth, so that the liquid supply of the liquid guide of the atomizer core 15 is affected, and the problem of pasting the core is caused.

The ventilation capillary groove 122 of the electronic heating atomization assembly 1 is communicated with the liquid return capillary groove 123, so that liquid (such as air pressure change extruded from the liquid storage bin 21 or atomized steam condensed in the device) gathered in the ventilation capillary groove 122 under some conditions flows back to the liquid guide piece 151 of the atomization core 15 through the liquid return capillary groove 123, and is absorbed and atomized by the liquid guide piece 151 in the working process, thereby ensuring ventilation smoothness of the ventilation capillary groove 122 and ensuring smoother and more stable ventilation.
