The resistance-type heating element 3 in the inner absorption layer 2 is used for heating and converting the smoke liquid in the inner absorption layer 2 into aerosol (steam) through heating and atomization.

Because the outer surface area of the side surface protrusion 11 is far less than the surface area of the atomization cavity 5 of the atomization assembly, the liquid inlet amount is limited, the smoke liquid entering from the side surface protrusion 11 can be diffused and distributed in the inner absorption layer 2, the smoke liquid in the inner absorption layer 2 can not be gathered on the surface of the atomization cavity 5 of the atomization assembly in the inner absorption layer 2 too much and overflow occurs, and the liquid contained in the micro ceramic hole of the inner absorption layer 2 has surface tension, therefore, when the atomization assembly does not work, the smoke liquid can reach a balance in the inner absorption layer 2, the liquid can not flow out from the micro hole on the surface of the atomization cavity 5 of the atomization assembly in the inner absorption layer 2, and liquid leakage can be prevented.

Air enters the atomizing chamber 5 through the peripheral air supply holes 12, the peripheral air supply holes 12 are formed in the baffle plate 13, and the baffle plate 13 is located in the air inlet branch pipe 9 of the atomizing assembly shell 1.

During smoking, when a user inhales, air enters the atomizing assembly from the atmosphere through the air-fed atomizer system, specifically through the air inlet 16, the air passage 17, the air inlet tube 18, and then through the air inlet channel 6, the peripheral air feed holes 12 in the baffle plate 13 into the atomizing chamber 5 of the atomizer.

When a user inhales, the power supply voltage supplies power to the lead 4, the lead 4 is electrified to the resistance heating element 3 through the connection of the central contact element 19 and the external thread contact element 20, and the resistance heating element 3 starts to heat rapidly (the maximum allowable temperature can reach +290 ℃ and 300 ℃).

The liquid in the region of the resistive heating element 3 begins to be actively atomized in aerosol form into the atomizing chamber 5, which mixes with air entering through peripheral air feed holes 12 provided in a baffle 13, which baffle 13 is located in the air inlet manifold 9 of the atomizing assembly housing 1.

The air mixture then flows through the spray tube 22, through the suction nozzle 26 and into the mouth of the user.
