Please refer to FIG. 8 and FIG. 9 , FIG. 8 is a schematic diagram of the airflow mode in the atomization assembly provided by the present application, and FIG. 9 is a schematic diagram of the airflow mode of the atomizing seat in the atomizing assembly provided by the present application.

For the conventional heating element 30 , the atomizing surface is usually disposed toward the power supply assembly 2 , and the heating element 312 is disposed on the atomizing surface, so the smoke generated on the atomizing surface must bypass the heating element 30 itself and be absorbed by the user.

A through hole is provided on the bottom wall of the atomization base 22 close to the power supply assembly 2 , serving as the air intake channel 221 of the atomization assembly 1 . Since the atomization chamber 23 is formed between the atomization top seat 21 and the atomization base 22, the heating element 30 is arranged in the atomization chamber 23, and the atomization surface of the heating element 30 faces the suction nozzle 11 and away from the power supply element 2, and the outside air After entering the atomizing assembly 1 from the air inlet channel 221, it reaches the atomizing surface along the side wall of the heating assembly 30, that is, the air flow in the air inlet channel 221 enters the atomizing chamber 23 from the top of the two sides of the heating body 31, and then atomizes the atomization surface. The atomized gas in the cavity 23 is carried out from the air outlet channel 12, reaches the suction nozzle 11, and is sucked by the user.

By setting the atomizing surface of the heating component 30 away from the power supply component 2 and facing the suction nozzle 11 ; that is, the ambient air does not directly impact the atomizing surface. The heating element 312 is arranged on the atomizing surface. When the heating element 312 generates heat, the liquid on the atomizing surface absorbs the heat and is atomized, and the generated smoke does not need to pass through the heating element 30 itself and directly enters the air outlet channel 12 and the suction nozzle 11 to be sucked by the user, thereby reducing The loss generated when the smoke passes through the heating element 30 itself ensures that a sufficient amount of smoke is effectively absorbed by the user in a unit time, thereby increasing the effective amount of smoke generated by the electronic atomizer device in a unit time. The distance from the atomizing surface to the suction nozzle 11 is relatively small, which can control the outlet temperature of the smoke, and also reduce the loss of smoke in the air outlet channel 12, thereby ensuring the effective amount of smoke generated by the electronic atomization device per unit time. Therefore, when the effective smoke volume of the electronic atomization device is the same, setting the atomization surface of the heating element 30 to face the suction nozzle 11 is beneficial to reduce the consumption of electric energy during the atomization of the heating element 30, and can improve the power supply assembly 2 battery life.

The atomizing surface is disposed toward the suction nozzle 11, which can reduce the rapid condensation of the smoke, and further reduce the condensation of the smoke in the atomization chamber 23, so as to prevent excessive condensate from affecting the use of the electronic atomization device. In addition, the distance from the atomizing surface to the mouthpiece 11 is relatively small, so that the path that the smoke flows from to the mouthpiece 11 is the shortest, which can prevent the loss of nicotine or aroma in the smoke, and make it easier to remove the large amount of smoke in the smoke. The particles are carried out, thereby enhancing smoke taste and satisfaction.

In another embodiment, the atomizing surface of the heating element 30 can also be arranged away from the suction nozzle 11 and toward the power supply element 2, and the specific structure of the heating element 30 needs to be changed accordingly. For example, the heating element 30 is disposed on the atomization base 22 and forms an atomization cavity 23 with the installation groove of the atomization base 22 .
