The circuit board 52 is used for controlling the atomizing structure 2, etc., and can make the electronic atomizing generating device work on the atomizing structure 2 when sucking, and stop the atomizing structure 2 when stopping sucking.

The charging structure 53 is used for being connected with an external power supply to charge the electronic atomization generating device, so that the electronic atomization generating device is convenient to carry and use for users. The interface Type of the charging structure 53 is not limited herein, and may be a Type-C interface, a USB interface, or the like.

The housing assembly 1 is used for accommodating the above structures and protecting the oil storage structure 3, the atomizing structure 2, the circuit board 52, the charging structure 53, and the like.

The circuit board 52 and the charging structure 53 are both disposed in the second accommodating cavity 114, the charging structure 53 and the circuit board 52 are fixed to each other, and the charging structure 53 is electrically connected to the circuit board 52, so that the charging structure 53 and the circuit board 52 are not located in the atomizing air channel 101. And the second accommodating chamber 114 is provided with a charging port 111, and the charging port 111 exposes the charging structure 53, so that an external power line or power supply can be connected to the charging structure 53. Because the charging port 111 is formed in the cavity wall of the second accommodating cavity 114 and is separated from the atomizing air passage 101 in the first accommodating cavity 1232, when a user sucks, the atomizing air passage 101 does not pass through the charging port 111, whether the charging port 111 is sealed or whether the sealing performance is good or not does not influence the atomizing air passage 101, air leakage from the charging port 111 is avoided, and the suction force is easier to control.

Wherein, the air inlet 102, the suction port 103 and the charging port 111 are all arranged on the housing assembly 1.

In the electronic atomization generating device in the above embodiment, the housing assembly 1 is provided with the first accommodating cavity 1232 and the second accommodating cavity 114 which are separated from each other, the oil storage structure 3 and the atomization structure 2 are arranged in the first accommodating cavity 1232, the atomization air passage 101 is formed in the first accommodating cavity 1232, the first accommodating cavity 1232 is provided with the air inlet 102 and the suction port 103, the circuit board 52 and the charging structure 53 are arranged in the second accommodating cavity 114, and the second accommodating cavity 114 is provided with the charging port 111. Because the first accommodating cavity 1232 and the second accommodating cavity 114 are separately arranged, the first atomization air passage 101 and the charging port 111 are mutually separated, and the sealing performance of the charging port 111 cannot influence the suction force of the electronic atomization generating device, so that the sealing piece at the charging port 111 can be reduced, and the sealing effect of the atomization air passage 101 is better.

In one embodiment of the present utility model, referring to fig. 2 and 6, the electronic atomization generating device further includes an airflow sensor 4, and the airflow sensor 4 is disposed outside the first accommodating cavity 1232, that is, the airflow sensor 4 is disposed outside the atomization air passage 101.

The outer intake port 1021 and the inner intake port 1022 communicate with each other, and the outer suction port 1031 and the inner suction port 1032 communicate with each other. Optionally, the housing structure 11 is provided with a suction nozzle 113, and the external suction port 1031 is provided on the suction nozzle 113.

The first sealing seat 121 and the second sealing seat 122 are used for sealing the openings at two ends of the main casing 123, so that the inner casing structure 12 is arranged in a sealing manner, and oil leakage is prevented.

Alternatively, the first seal seat 121 and the second seal seat 122 are both flexible seal seats that can be deformed, such as flexible seal seats made of a flexible material such as rubber, silicone, or the like. In this way, the first sealing seat 121 and the second sealing seat 122 not only can be used as structural members for sealing two ends of the main casing 123, but also can be used as sealing members without additional sealing members. Specifically, the first sealing seat 121 is clamped to one end of the housing structure 11 and the main casing 123, so that the main casing 123 and the first sealing seat 121 are in sealing connection, and the second sealing seat 122 is clamped to the other end of the housing structure 11 and the main casing 123, so that the main casing 123 and the second sealing seat 122 are in sealing connection, and the first accommodating cavity 1232 is arranged in a sealing manner, so that air flow only enters from the air inlet 102 and is discharged from the suction port 103, and no air leakage occurs from the connection of the main casing 123 and the first sealing seat 121 and the connection of the main casing 123 and the second sealing seat 122.

When the electronic atomization generating device is normally used, as oil is atomized at the atomization structure 2, part of fog drops can be condensed into liquid again, but the condensed liquid cannot enter the oil storage structure 3 again, so that the liquid can flow in the first accommodating cavity 1232 and flow out of the air inlet 102 or the suction port 103, and an oil leakage phenomenon occurs. The oil absorbing cotton 6 is arranged between the second sealing seat 122 and the shell structure 11 to absorb a certain amount of condensed oil, so that the oil is prevented from flowing out of the air inlet 102.

Optionally, the air flow sensor 4 is also fixed on the first sealing seat 121, so that the air flow sensor 4 and the inner suction opening 1032 are disposed on the same side of the inner shell structure 12, and are disposed away from the oil storage structure 3 and the atomization structure 2, so as to prevent the oil leakage or the mist drops of the oil storage structure 3 from liquefying and flowing onto the air flow sensor 4, thereby avoiding the air flow sensor 4 from being damaged by the oil leakage or from being started after being infiltrated by the oil. The airflow sensor 4 has a detection film, and the opposite sides of the film are the pressure release side and the sensing side, respectively, so that the detection film is immersed by oil liquid, which can cause misjudgment and failure of the airflow sensor 4.
