Wherein, as the atomizer body 50 rotates, the area of coincidence of the inlet of the air intake passage 51 with the air intake port 13 increases or decreases to open or close the inlet of the air intake passage 51. Like this, rotationally set up atomizer main part 50 on electronic atomization device 100, when atomizer main part 50 is rotatory, inlet channel 51's entry on atomizer main part 50 coincides with air inlet 13 gradually, and the coincidence area between them crescent makes inlet channel 51's entry gradually opened, and the area of crossing of inlet channel 51 entry crescent, and the resistance of breathing in reduces, satisfies the demand that user's lung inhaled and uses electronic atomization device 100. Or, when the atomizer body 50 rotates, the inlet of the air inlet channel 51 on the atomizer body 50 is gradually dislocated with the air inlet 13, the overlapping area of the two is gradually reduced, so that the inlet of the air inlet channel 51 is gradually closed, the air passing area of the inlet of the air inlet channel 51 is gradually reduced, and the air suction resistance is gradually increased, so as to meet the requirement of the user for using the electronic atomization device 100 by oral inhalation.

Moreover, the atomizer body 50 can be rotatably arranged, so that stepless adjustment of suction resistance can be realized, and the adjustment precision is higher.

Furthermore, the atomizer main body 50 can rotate 360 degrees relative to the battery pack 10, so that the inlet of the air inlet channel 51 on the atomizer main body 50 can be completely overlapped or completely dislocated with the air inlet 13 along with the rotation of the atomizer main body 50, the air suction resistance can be adjusted to the maximum extent, and the suction nozzle can be adjusted in a large range. It is understood that in other embodiments, the atomizer body 50 may rotate at other angles against the battery assembly 10, and the inlet of the air inlet channel 51 may be opened and closed to the maximum extent, which is not limited herein.

In other embodiments, the atomizer body 50 is rotatably connected to the housing 12, and the housing 12 is detachably connected to the battery assembly 10, which means that the atomizer body 50 and the housing 12 are rotatably connected and then combined into a whole, and the whole of the atomizer body 50 and the housing 12 can be replaced by detachably connecting the housing 12 to the battery assembly 10.

Thus, the external air flow firstly flows to the first sub-channel 512 through the air inlet 13, then flows to the atomizing chamber 70 from the second sub-channel 514 to carry the atomized aerosol, and finally flows to the outside for the user to eat. The first sub-channel 512 is intersected with the atomizer main body 50 in the axial direction, which is equivalent to air intake from the side surface of the atomizer main body 50, and air flow does not need to pass through the inside of the battery assembly 10, so that potential safety hazards of condensed water formed in the air intake channel 51 to the battery assembly 10 are prevented.

Further, the atomizer main body 50 includes a support 60 and an atomizing assembly 80, the atomizing assembly 80 is disposed in the support 60, and the support 60 is provided with a first sub-passage 512 and a second sub-passage 514. The first conductor 52 and the second conductor 54 are both disposed on the bracket 60 and electrically connected to the atomizing assembly 80, so that the first conductor 52 and the second conductor 54 serve as connection points for electrically connecting the atomizing assembly 80. Meanwhile, the atomizing assembly 80 is fixedly installed through the bracket 60, and a first sub-channel 512 and a second sub-channel 514 for ventilating the atomizing assembly 80 are formed on the bracket 60, so that an atomizing function is realized.

Furthermore, the second sub-channel 514 is disposed to surround a part of the outer circumference of the first conductive body 52, and the second sub-channel 514 itself extends in a curved shape, so that the condensate formed in the second sub-channel 514 can be effectively prevented from leaking.

Moreover, the two first sub-channels 512 extend along the same radial direction of the atomizer body 50, and the two air inlets 13 on the battery pack 10 are oppositely arranged along the radial direction of the atomizer body 50. In this way, when one air inlet on the atomizer main body 50 completely coincides with one air inlet 13 on the battery assembly 10, the other air inlet on the atomizer main body 50 also completely coincides with the other air inlet 13 on the battery assembly 10, and at this time, both air inlets on the atomizer main body 50 are opened, so that the air suction resistance is minimum, and the air intake amount is maximum.
