When the operating element 22 is rotated to the open position relative to the end cover element 21, the limiting protrusion 223 of the operating element 22 abuts against the first end of the limiting recess 210 to form a limit; and when the operating element 22 is rotated to the open position relative to the end cover element 21, the limiting protrusion 223 of the operating element 22 can also extend into the first locking groove 212 to form a lock, so as to prevent the operating element 22 from rotating from the open position to the closed position relative to the end cover element 21. Accordingly, when the operating element 22 is rotated to the closed position relative to the end cover element 21, the limiting protrusion 223 of the operating element 22 abuts against the first end of the limiting recess 210 to form a limit; and when the operating element 22 is rotated to the open position relative to the end cover element 21, the limiting protrusion 223 of the operating element 22 can also extend into the first locking groove 212 to form a lock, so as to prevent the operating element 22 from rotating from the open position to the closed position relative to the end cover element 21. When in the closed position, the limiting protrusion 223 of the operating element 22 abuts against the second end of the limiting recess 210 to form a limit; and when the operating element 22 rotates to the closed position relative to the end cover element 21, the limiting protrusion 223 of the operating element 22 can also extend into the second locking groove 213 to form a lock, so as to prevent the operating element 22 from rotating from the closed position to the open position relative to the end cover element 21.

In the end cap assembly 20 having the structure shown in FIGS. 3 to 8 , the operating element 22 can be operated by the user and selectively form different connection states with the end cap element 21; for example, it can have a first connection state and a second connection state. Among them, in the first connection state between the operating element 22 and the end cap element 21, the operating element 22 cannot drive the end cap element 21 to move or be removed from the housing 10/connection element 19, but can only move relative to the end cap element 21 to selectively open and close the air inlet 215. In the second connection state between the operating element 22 and the end cap element 21, the operating element 22 can form a synchronous movement with the end cap element 21, and then in the second connection state, the operating element 22 can drive the end cap element 21 to move or be removed from the housing 10/connection element 19.

In the first connection state, the user operates the operating element 22 with a finger, thereby driving the operating element 22 to move and thus opening or closing the air inlet 215. The operation process is shown in FIGS. 9 to 12 .

Among them, FIG9 shows a schematic diagram of the operating element 22 in the open position; in FIG9, the convex edge 222 of the operating element 22 is inserted into the air inlet 215 of the end cover element 21, and the air inlet avoidance hole 221 of the operating element 22 is aligned with the air inlet 215 and is connected, and the external air can enter the electronic atomization device 100 along the arrow R2 in FIG9. And in the open position shown in FIG9, the operating element 22 is locked and cannot be rotated toward the open position. For example, in FIG9, one aspect of the operating element 22 is locked by the convex edge 222 extending into the air inlet 215. Correspondingly, in the open position of FIG9, the limiting protrusion 223 of the operating element 22 is also extended into the first locking groove 212 to form a lock. In the locking shown in FIG9, the elastic element 25 is in elongation.

FIG10 shows a schematic diagram of a user unlocking the operating element 22 in the open position in FIG9 by pulling the operating element 22. As shown by arrow P11 in FIG10, the operating element 22 is pulled outward by the user's fingers to move the operating element 22, so that the convex edge 222 is moved out of the air inlet 215, and the limiting protrusion 223 is disengaged from the first locking groove 212, thereby unlocking. In the unlocked state shown in FIG10, there is a first spacing d1 between the operating element 22 pulled outward and the housing 10/connecting element 19; in some examples, about In the unlocked state shown in FIG10 , the elastic element 25 is compressed.

FIG. 11 shows a schematic diagram of a user rotating the operating element 22, which is in unlocked state in FIG. 10, from an open position to a closed position; as indicated by arrow P12 in FIG. 11, the rotation of the operating element 22 is performed around its central axis. In some embodiments, the rotation operation of the operating element 22 along the arrow P12 is 90 degrees and is limited by the limiting recess 210 of the end cover element 21. In FIG. 11, the air intake avoidance hole 221 of the operating element 22 rotated to the closed position is staggered with the air intake port 215 of the end cover element 21; and, in the closed position, the air intake avoidance hole 221 is aligned with the blind hole 216 of the end cover element 21; and, in the closed position, the limiting protrusion 223 of the operating element 22 is aligned with the second locking groove 213.

FIG12 shows a schematic diagram of the operation element 22 moving from unlocked to locked in the closed position of FIG11 driven by the elastic restoring force of the elastic element 25; as shown by arrow P13 in FIG12, driven by the elastic restoring force of the elastic element 25 in compression in FIG11, the operation element 22 is biased toward the end cover element 21, so that the convex edge 222 extends into the blind hole 216, and the limiting protrusion 223 extends into the second locking groove 213 to form a lock, so as to keep the operation element 22 in the closed position and prevent it from rotating to the open position. When the operation element 22 is driven to be locked by the elastic element 25,

Figure 13 is a schematic diagram from another perspective of the operating element 22 being driven to lock by the elastic element 25 in the closed position; as shown in Figure 13, when the operating element 22 is in the closed position, the air intake avoidance hole 221 is aligned with the blind hole 216 of the end cover element 21 and is closed; and, the protrusion 222 extends into the blind hole 216 to prevent the operating element 22 from rotating relative to the end cover element 21.

Correspondingly, when the user needs to rotate the operating element 22 from the closed position to the open position, the operation can be performed in the opposite manner to that shown in FIGS. 9 to 12 above.

In FIG. 4 , the end cap assembly 20 is connected to the connecting element 19, thereby maintaining connection with the housing 10. In FIG. 4 , the operating element 22 is in the open position and locked. As shown in FIG. 4 and FIG. 14 , a slot 191 for connecting with the end cap 20 is arranged on the connecting element 19; the slot 191 includes a first portion 1911 extending in the circumferential direction, and a second portion 1912 extending from the first portion 1911 in the axial direction toward the distal end 120; and the second portion 1912 is open toward the distal end 120.

As shown in FIG. 14 , the first portion 1911 has a first end and a second end opposite to each other; The first end of the part 1911 has a notch 1913; the second part 1912 extends axially from the second end of the first part 1911. After assembly, the protrusion 211 of the end cover element 21 is inserted into the notch 1913, thereby preventing the protrusion 211 of the end cover element 21 from rotating circumferentially from the first part 1911 to the second part 1912. And in FIG. 4, when the protrusion 211 is inserted into the notch 1913, the end cover element 21 may be locked, that is, the end cover element 21 cannot rotate relative to the connecting element 19 in the circumferential direction to rotate the protrusion 211 from the first part 1911 to the second part 1912.

In the embodiment, the process of disassembling the end cover assembly 20 from the housing 10 is shown in FIGS. 14 to 18 .

As shown by arrow P21 in FIG. 14 , the user holds the operating element 22 with fingers and pulls it outward to unlock it in the closed position or the open position, so that the operating element 22 can rotate relative to the end cover element 21 ;

As shown by arrow P22 in Figure 15, the user holds the operating element 22 with his fingers and rotates it until the limiting protrusion 223 rotates to align with the connecting port 214 of the end cover element 21, thereby defining a disassembly operation position for disassembling the end cover assembly 20; as shown in Figure 15, the connecting port 214 is located between the first locking groove 212 and the second locking groove 213; the rotation angle of the operating element 22 from the open position or the closed position to the disassembly operation position is 45 degrees.

As shown by arrow P23 in FIG. 16 , in the disassembly operation position, the user presses the operating element 22 so that the limiting protrusion 223 of the operating element 22 extends into the connection port 214 to form a connection between the operating element 22 and the end cover element 21, thereby being used to disassemble the end cover assembly 20 from the housing 10. As shown in FIG. 16 , when the limiting protrusion 223 extends into the connection port 214, a second spacing d2 is provided between the operating element 22 and the housing 10/connection element 19; the second spacing d2 is smaller than the first spacing d1; in some examples, the second spacing d2 is approximately 1 mm.

As shown by arrow P24 in FIG. 17 , in the disassembly operation position, the user further presses the operating element 22, and the limiting protrusion 223 extends into the connection port 214, thereby driving the end cover element 21 to move toward the proximal end 110, so that the locking protrusion 211 of the end cover element 21 is disengaged from the recess 1913 of the first part 1911 of the connection element 19. In FIG. 17 , after the locking protrusion 211 of the end cover element 21 is disengaged from the recess 1913 of the first part 1911 of the connection element 19, the end cover element 21 is unlocked, thereby allowing the end cover element 21 to rotate relative to the connection element 19 in the circumferential direction. As shown in FIG. 17 , the pressed operating element 22 abuts against the connection element 19 and/or the housing 10. And as shown in FIG. 17 , after the limiting protrusion 223 extends into the connection port 214, the operating element 22 can be disassembled. The operating element 22 is connected and fastened to the end cover element 21 to prevent them from rotating or moving relative to each other; then, further, the user can drive the end cover element 21 to move and rotate by pressing and rotating the operating element 22, thereby being able to remove the end cover element 21 from the housing 10/connecting element 19.

According to arrows P25 and P26 in FIG. 18 , in the state where the protrusion 211 and the recess 1913 are disengaged in FIG. 17 , the end cover element 21 is further driven to move by operating the operating element 22 to remove the end cover element 21 from the housing 21/connecting element 19. According to arrows P25 and P26, the specific moving operation includes: firstly operating the operating element 22 to rotate, so as to drive the end cover element 21 to rotate until the protrusion 211 rotates from the first part 1911 to the second part 1912; then pulling the operating element 22 downward, so that the protrusion 211 of the end cover element 21 connected by the countersunk screw 24 is removed from the second part 1912; after removal, the protrusion 211 is separated from the slot 191 and then contacts the end cover element 21 to connect with the housing 10. Then, all other parts of the end cover assembly 20 are removed from the housing 10 together with the end cover element 21.

As shown in FIG. 19 , after the end cap 20 is removed from the distal end 120 of the housing 10, the distal end 120 of the housing 10 of the electronic atomization device 100 is opened or exposed. Then, the user can take out or remove the battery cell 40 from the distal end 120 of the housing 10 by slightly shaking or gently swinging. When the battery cell 40 is removed, the conductive connection can be disconnected by releasing the contact with the first elastic electrical contact 62.

As shown in FIG7 , the exposed surface of the operating element 22 is also provided with graphic or textual indications for indicating that the operating element 22 is in different positions; for example, in FIG7 , the operating element 22 is provided with textual indications of “ON” and “OFF” for prompting or telling the user the open position and the closed position of the operating element 22, as well as indicating the rotational direction for rotating the operating element 22 between them.

As shown in Fig. 7, the connection opening 214 of the end cover element 21 is shallower than the first locking groove 212 and the second locking groove 213. Therefore, when the limiting protrusion 223 is only located in the connection opening 214, the locking protrusion 211 of the end cover element 21 can be disengaged from the notch 1913 of the first part 1911 by pressing and driving while maintaining the second spacing d2.
