The airflow sensor 40a is located between the partition wall 21a and the battery cell 16a to sense the airflow flowing through the airflow channel.

As shown in FIGS. 13 to 17 , the electronic atomization device 100a further includes:

The operating assembly 30a is installed in the inner shell 20a and arranged near the distal end 120a; during assembly, the operating assembly 30a passes through the mounting hole 23a of the partition wall 21a and is firmly held in the inner shell 20a. In this embodiment, the operating assembly 30a includes:

The countersunk screw 31a includes a screw head 311a and a screw rod 312a;

A flexible sealing element 32a having an escape notch 321a;

The elastic element 33a is, for example, a spring;

The operating element is operated by the user to drive the sealing element 32a to open or close the air inlet 22a, or to unlock the air inlet 22a; in this embodiment, the operating element includes a first operating component 34a and a second operating component 35a connected to each other; wherein the first operating component 34a is provided with a card slot; the second operating component 35a is provided with a card hook 353a, which is connected to the card slot 343a of the first operating component 34a through the card hook 353a to be fastened to the first operating component 34a; the exposed surface of the second operating component 35a is provided for the user to operate;

A charging connector 36a, such as a USB type-C charging connector, etc., for charging the battery cell 16;

The charging circuit board 37a is electrically connected to the charging connector 36a and is electrically connected to the battery cell 16a or the main control circuit board through welding leads or the like; the charging circuit board 37a is used to control the charging process of the battery cell 16 through the charging connector 36a, such as the charging current or power;

The charging connector 36a and the charging circuit board 37a are accommodated and retained in the operating element composed of the first operating component 34a and the second operating component 35a; and after assembly, the charging connector 36a and the charging circuit board 37a are firmly retained in them by the second operating component 35a and the first operating component 34a; the second operating component 35a is at least partially exposed, so as to be operated by the user to drive the sealing element 32a to open or close the air inlet 22a; the second operating component 35a has a charging port 354a, which is opposite to the charging connector 36a and is connected to an external connector.

After assembly, the countersunk screw 31 penetrates the sealing element 32a and is connected to the first operating component 34a, thereby establishing a connection between the sealing element 32a and the second operating component 35a. And the elastic element 33a is installed between the first operating component 34a and the partition wall 21a. And during assembly Afterwards, a gap is maintained between the inner shell 20a and the operating component 30, and the port of the air inlet 22a toward the distal end 120a is connected to the outside atmosphere through the gap between the inner shell 20a and the operating component 30.

As shown in Figures 13 to 17, a first limiting protrusion 24a is also arranged in the inner shell 20a; a second limiting protrusion 351a is arranged on the second operating component 35a; and the first limiting protrusion 24a and the second limiting protrusion 351a cooperate to form an abutment stop when driving the second operating component 35a to rotate, thereby providing a limit when rotating to the open position and/or the closed position.

As shown in Figures 13 to 17, the sealing element 32a is located between the battery cell 16a and the partition wall 21a; and in this embodiment, the surface 3210a of the sealing element 32a facing the partition wall 21a does not have a connection structure for connecting with the partition wall 21a to form a lock. Furthermore, in this embodiment, the surface 3210a of the flexible sealing element 32a is tightly attached to the partition wall 21a under the elastic bias of the elastic element 33a, and has a large friction or damping force. When the user drives the second operating component 35a to rotate and the sealing element 32a rotates relative to the partition wall 21a, the friction or damping force between the surface 3210a and the partition wall 21a is used to form a lock, and at this time, the user drives the second operating component 35a to rotate, which is relatively unsmooth in operation. When the user presses the second operating component 35a to move the sealing element 32a to the surface 3210a and separate from the partition wall 21a, the friction or damping force therebetween is eliminated to form unlocking, so that the user can drive the second operating component 35a to rotate smoothly.

In this embodiment, the process in which the user drives the sealing element 32a to open or close the air inlet 22a through the second operating component 35a is shown in FIGS. 18 to 21 .

As shown in FIG. 18 , the sealing element 32a is pressed against the partition wall 21a under the bias of the elastic element 33a, and the avoidance notch 321a of the sealing element 32a is staggered with the air inlet 22a, so that the air inlet 22a is closed by the sealing element 32a. In FIG. 19 , the user presses the second operating component 35a as shown by the arrow P1 to separate the sealing element 32a from the partition wall 21a, for example, in FIG. 19 , they are separated by pressing to have a spacing d1 to release their contact lock. In FIG. 20 , the user rotates the second operating component 35a to drive the sealing element 32a to rotate, so that the avoidance notch 321a of the sealing element 32a is aligned with the air inlet 22a to open the air inlet 22a. In FIG. 21 , the elastic restoring force of the elastic element 33a drives the sealing element 32a to abut against the partition wall 21a to form a lock in the open position.

Similarly, the user can also operate according to the reverse operation process to drive the sealing element 32a to adjust from the open position to the closed position, thereby closing the air inlet 22a.

As shown in Figures 18 to 21, the charging connector 36a and the charging circuit board 37a move synchronously with the movement of the second operating member 35a. Accordingly, in the embodiment, by reserving a sufficient length of the conductive lead connecting the charging circuit board 37a with the main control circuit board, the length of the conductive lead is sufficient to maintain the connection with the main control circuit board during the movement of the charging circuit board 37a.

FIG. 22 shows a schematic diagram of an electronic atomization device 100b according to another variant embodiment. In this embodiment, the electronic atomization device 100b includes:

A main housing 10b, and an end cover 20b located in the main housing 10b; the end cover 20b is arranged near the distal end 120b;

The battery cell 16b is located in the main housing 10b and is used to supply power to the atomizer assembly;

The end cover 20b has a partition wall 21b arranged perpendicular to the longitudinal direction, and an air inlet 22b is arranged on the partition wall 21b;

The elastic element 33b, such as silicone or thermoplastic elastomer, is arranged between the battery cell 16b and the partition wall 21b;

The sealing element 32b of the operating component 30b is located between the partition wall 21b and the elastic element 33b, and the countersunk screw 31b penetrates the sealing element 32b and is connected to the operating element 34b, thereby establishing a connection between the sealing element 32b and the operating element 34b; in use, the user operates the sealing element 32b to move and rotate longitudinally, thereby configuring the sealing element 32b between a closed position closing the air inlet 22b and an open position opening the air inlet 22b.

In the embodiment of FIG22 , the elastic element 33b located between the battery cell 16b and the partition wall 21b replaces the spring to provide elastic force, so that the sealing element 32b is biased toward the locked state against the partition wall 21b. When the user presses the operating element 34b to unlock, the countersunk screw 31b squeezes the elastic element 33b; when the user completes the operation, the elastic restoring force of the compressed elastic element 33b drives the countersunk screw 31b and the sealing element 32b to move toward the partition wall 21b to form a lock, as shown by arrow P3 in FIG22 .

In the embodiment shown in FIG. 22 , the airflow sensor 40 b is wrapped or mounted within the elastic element 33 b .
