According to the electronic atomizer 100, the suction resistance of the electronic atomizer 100 can be more diversified by independently adjusting the flow rate of the air flowing into the first air channel, so that different requirements of users can be met. Meanwhile, since the charging hole 143 is separately communicated with the second air passage 18 and is isolated from the first air passage by the blocking member 50, the arrangement of the charging hole 143 does not affect the adjustment of the air flow rate of the first air passage, so that the charging hole 143 is not required to be additionally sealed, the accuracy of air flow adjustment is improved, and the structure of the electronic atomizer 100 is simplified.

The control assembly 40 is located within the second air passage 18 and is thus communicable with the external atmosphere through the second air passage 18. Specifically, the control assembly 40 includes a circuit board 41, a charging interface 43, and an airflow sensor 45.

One end of the charging interface 43 is connected to a side surface of the circuit board 41 away from the blocking member 50 in the second direction, and the other end of the charging interface 43 extends along the first direction to be inserted into the charging hole 143, so that the charging connector can be inserted into the charging interface 43 through the charging hole 143. Since the charging interface 43 is located within the second air passage 18, no sealing of the charging interface 43, the gaps between the charging interface 43 and the housing 12 is required.

The air flow sensor 45 is disposed at the other end of the circuit board 41 away from the charging interface 43 in the second direction and is located at one side of the circuit board 41 facing the blocking member 50, the air flow sensor 45 has a first sensing surface and a second sensing surface which are oppositely disposed in the first direction, the first sensing surface is communicated with the external atmosphere through the second air passage 18 to sense the external atmospheric pressure, and the second sensing surface is communicated with the atomizing cavity to sense the air pressure in the atomizing cavity. Thus, when the user sucks the electronic atomizer 100, the air pressure difference exists between the air pressure sensed by the second sensing surface and the air pressure sensed by the first sensing surface, so that the air flow sensor 45 sends a signal to the circuit board 41, and the circuit board 41 controls the battery assembly 30 to supply power to the atomizing core 25 according to the signal.

The blocking member 50 has a plate-like structure, the thickness direction of the blocking member 50 extends along the first direction, one end of the blocking member 50 in the second direction abuts between the lower cover 14 and one end of the circuit board 41 provided with the air flow sensor 45, so that the charging interface 43 is spaced at one side of the blocking member 50 in the second direction, and the charging interface 43 extends into the charging hole 143 through the space between the blocking member 50 and the main housing 10 along the first direction.

In some embodiments, the electronic atomizer 100 further includes an adjusting member 60, where the adjusting member 60 is mounted on the lower cover 14 and located at one side of the blocking member 50, and the adjusting member 60 is movable relative to the lower cover 14 to open or block the air inlet hole 141, thereby adjusting the air flow into the first air passage.

Specifically, in one embodiment, the lower cover 14 is provided with a mounting groove 145 between the charging hole 143 and the air intake hole 141, the adjusting member 60 includes an adjusting member main body 61 and a control portion 63, the adjusting member main body 61 has a plate-shaped structure to be attached to a side surface of the blocking member 50, and the control portion 63 is disposed on a side of the adjusting member main body 61 away from the blocking member 50 and extends into the mounting groove 145. Thus, the user can toggle the control part 63 to drive the adjusting piece 60 to reciprocate along the second direction so as to change the area of the adjusting piece main body 61 covering the air inlet hole 141, thereby adjusting the air flow flowing into the first air passage. When the regulator main body 61 completely shields the intake hole 141, the amount of intake air into the first air passage is substantially zero, and when the regulator main body 61 completely exposes the intake hole 141, the amount of intake air into the first air passage reaches a maximum value.

The electronic atomizer 100 forms the first air passage and the second air passage 18 which are independently arranged through the assembly of the blocking member 50, the first air passage is used for adjusting the air flow, the arrangement of the second air passage 18 can prevent the air flow flowing in from the charging hole 143 from affecting the air flow adjustment of the first air passage, and the first sensing surface of the air flow sensor 45 can be always communicated with the external atmosphere, so that the normal operation of the air flow sensor 45 is ensured, and the position of the charging hole 143 is not required to be sealed by an additional sealing member.
