Specifically, as shown in fig. 1, in order to make the airflow better mix with the smoke generated by the atomization of the heat generating component 12, in the embodiment of the present invention, the hole wall of the air passing hole 114 is designed to be inclined to form a flow guiding surface 1141, and an extension 1141' of a side of the flow guiding surface 1141 exposed from the atomization groove 111 intersects with the heat generating component 12. To direct an air flow to the heat generating component 12. Here, the air passing hole 114 is located below the heat generating component 12, so that the hole wall of the lower end of the air passing hole 114 gradually decreases from the side close to the atomizing groove 111 to the side far from the atomizing groove 111, and an extension line 1141' of the hole wall of the lower end of the air passing hole 114 extending from the atomizing groove 111 is directly opposite to the heat generating component 12. By guiding the airflow, the airflow is further ensured to flow into the atomization groove 111 from the air passing hole 114, mixed and atomized to generate smoke, and then flows out of the groove opening. Meanwhile, the air vent 114 is designed to be inclined, so that the phenomenon that the smoke liquid is deposited in the air vent 114 and is inconvenient to clean is effectively prevented.

Specifically, as shown in fig. 1 in combination with fig. 8 and 9, in the embodiment of the present invention, the heat generating component 12 includes a heat generating component 121 and an oil absorbing component 122, the heat generating component 121 wraps a portion of an outer peripheral surface of the oil absorbing component 122, and when the heat generating component 12 is installed on the core seat 11, an extension 1141' of the flow guiding surface 1141 exposed on one side of the atomizing slot 111 intersects with the heat generating component 121, so as to guide the airflow to the heat generating component 121. The during operation, the piece 121 that generates heat under the drive of electric current to with the adsorbed tobacco juice of oil absorption piece 122 gasification in the twinkling of an eye production smog, when the user suction, external normal atmospheric temperature air current flows in air current passageway 112 through inlet port 113, rethread gas pocket 114 reaches water conservancy diversion face 1141 direction to the piece 121 surface that generates heat, mixes the smog of its production and supplies the user suction, simultaneously, can be right the piece 121 that generates heat cools down, and it is slower to avoid the temperature cooling of the piece 121 that generates heat, and the continuous suction of short time leads to leading the phenomenon production of oil piece damage.

Specifically, as shown in fig. 1 in combination with fig. 8 or 8, in the embodiment of the present invention, the heat generating member 121 is disposed in a hollow manner, the oil absorbing member 122 includes an oil absorbing part and a heat receiving part 1221, when the heat generating assembly 12 is mounted on the core base 11, an extension 1141' of the flow guiding surface 1141 exposed on one side of the atomizing groove 111 intersects with an outer peripheral surface of the heat generating member 121, the heat receiving part 1221 is filled in the hollow portion of the heat generating member 121, and the oil absorbing part extends from an end surface of the heat generating member 121 to the outside for absorbing smoke liquid. Here, in this embodiment, the oil absorption piece 122 is prepared by using a cotton material with oil storage performance, the cotton material of the heated portion 1221 is filled more tightly, so as to prevent the absorption of the tobacco juice and then generate larger deformation, and the oil absorption portion is looser, thereby helping to absorb more tobacco juice and improving the conductivity of the tobacco juice.

Therefore, the temperature of the two circumferential side walls of the atomizing slot 111 facing the heat generating member 121 is relatively high, and in this embodiment, the two airflow passageways 112 disposed on the two sides of the heat generating member 121 in the core seat 11 effectively form a thermal insulation cavity to prevent the temperature from being conducted to the outside of the base 30, which results in a relatively high temperature of the outer surface of the atomizing device 100. Meanwhile, the air holes 114 are formed in the two sides of the heating part 121, so that the phenomenon that the temperature of one side of the heating part 121 is high due to unilateral air flow and uneven heating is caused is effectively prevented.

Meanwhile, the generated smoke can flow out of each oil storage gap. The phenomenon that the heated part 1221 is deformed due to instantaneous large air pressure in the hollow part of the heating member 121 is prevented.
