A partial area of the shielding portion 340 is spaced apart from the wall of the second air passage 330 to surround the second air inlet hole 310 . It can be understood that since the shielding portion 340 is a part of the structure surrounding the second air inlet hole 310, when the shielding portion 340 does not at least partially block the first air inlet hole 222a, the first air inlet hole 222a can be Communicated with the second air inlet hole 310 . At this time, the aerosol generated by the atomizing component 200 can be transmitted from the second air channel 330 to the first air channel 221 through the first air inlet hole 222a and the second air inlet hole 310 for the user to inhale. The suction nozzle 300 and the sleeve 220 are arranged in this way, and their mutual cooperation is simple and reliable.

Furthermore, the positioning and assembly of the sleeve 220 relative to the suction nozzle 300 can also be facilitated by providing the shielding portion 340 to achieve Assembly of the sleeve and nozzle 300 is quick and accurate. That is to say, during assembly, the sleeve is drawn into the suction nozzle 300, and the sleeve moves along the inner wall of the suction nozzle 300 until the top wall 222 of the sleeve comes into contact with the shielding portion 340, that is, the sleeve and the suction nozzle 300 are completed. assembly.

Please refer to Figures 10 and 11. In one embodiment, regarding the blocking and sealing function of the blocking portion 340, for example with reference to Fig. 10, the first air inlet hole 222a can be a strip hole, and the blocking portion 340 has a corresponding shape. It has a long strip structure, and the size of the shielding part 340 is the same as the size of the first air inlet hole 222a, or the size of the shielding part 340 is larger than the size of the first air inlet hole 222a. In this way, in the second position, the shielding part 340 can fit the top wall 222 and completely cover the first air inlet hole 222a, so that the first air inlet hole 222a is closed. At this time, since the first air inlet hole 222a is closed, the first air inlet hole 222a and the second air inlet hole 310 are not connected.

When the suction nozzle 300 rotates from the second position to the first position, the elongated shielding portion 340 rotates to intersect with the first air inlet hole 222a. At this time, at least part of the first air inlet hole 222a is no longer covered by the shielding part 340. It can be understood that since the shielding portion 340 is a part of the structure surrounding the second air inlet 310, when at least part of the first air inlet 222a is no longer covered by the shielding portion 340, the first air inlet 222a Can communicate with the second air inlet hole 310. Of course, the suction nozzle 300 in the first position can be rotated relative to the sleeve 220 again until the shielding portion 340 completely covers the first air inlet hole 222a.

It can be understood that the above shapes of the first air inlet hole 222a and the shielding portion 340 are only examples. The first air inlet hole 222a and the shielding portion 340 can also be provided in other shapes according to requirements, and are not limited here.

In other embodiments, the shielding part 340 can also be provided on the top wall 222 of the sleeve 220. When the suction nozzle 300 rotates, it can move relative to the sleeve 220 to a position where the shielding part 340 completely covers the second air inlet 310, or the suction nozzle 300 can When the mouth 300 rotates, it can move relative to the sleeve 220 to a position where the shielding portion 340 at least partially does not cover the second air inlet hole 310 .

In one embodiment, one of the housing 100 and the suction nozzle 300 is provided with a limiting member 351 , and the other is provided with a positioning hole 1122 that matches the limiting member 351 . The number of positioning holes 1122 is at least two, and the two positioning holes 1122 are distributed along the circumference of the suction nozzle 300. In this way, when the suction nozzle 300 rotates relative to the housing 100, the limiting member 351 can be positioned and matched with the two positioning holes 1122 respectively. When the limiter 351 cooperates with one of the positioning holes 1122, the suction nozzle 300 is in the first position. When the limiter 351 cooperates with the other positioning hole 1122, the suction nozzle 300 is in the second position. By positioning and matching the stopper 351 with the two positioning holes 1122 respectively, it can be quickly determined whether the suction nozzle 300 accurately moves to the first position or the second position, and it is convenient for the suction nozzle 300 to switch back and forth between the first position and the second position. . At the same time, by positioning and matching the positioning members 351 with the two positioning holes 1122 respectively, the suction nozzle 300 can be stably maintained in the first position and the second position.

Please continue to refer to FIG. 8 and FIG. 9 . In one embodiment, the limiting member 351 is provided on the suction nozzle 300 and the positioning hole 1122 is provided on the housing 100 as an example. Of course, the same is true in reverse, so no further explanation will be given. Repeat.

The hole wall of the through hole 111 is provided with a fitting portion 1120 extending along the axial direction, and a limiting groove 1121 is defined on the end surface of the fitting portion 1120 . The limiting groove 1121 includes a bottom wall 1121a, a first groove wall 1121b and a second groove wall 1121c. The positioning hole 1122 is opened in the bottom wall 1121a of the limiting groove 1121. The first groove wall 1121b and the second groove wall 1121c are both connected to the bottom wall 1121a, and the first groove wall 1121b and the second groove wall 1121c are arranged oppositely. The suction nozzle 300 is provided with a contact portion 350 extending radially outward. The limiter 351 is provided on the contact portion 350 . The limiter 351 rotates with the suction nozzle 300 as a whole through the contact portion 350 . The contact portion 350 is movably provided in the limiting groove 1121. When the contact portion 350 contacts the first groove wall 1121b, the suction nozzle 300 is in the first position. When the contact portion 350 contacts the second groove wall 1121c, the suction nozzle 300 is in the first position. Mouth 300 is in the second position. In combination with the above, when the entire suction nozzle 300 is in the first position, the contact portion 350 is in contact with the first groove wall 1121b, and the limiting member 351 is positioned and matched with one of the positioning holes 1122; when the entire suction nozzle 300 is in the second position , the contact portion 350 is in contact with the second groove wall 1121c, and the limiting member 351 is positioned and matched with the other positioning hole 1122.

With this arrangement, the contact portion 350 abuts and cooperates with the first groove wall 1121b and the second groove wall 1121c respectively, so that the suction nozzle 300 can be quickly positioned to the first position or the second position when rotating. At the same time, by setting the limiting groove 1121, the rotation angle range of the suction nozzle 300 can also be limited, so that the suction nozzle 300 can only rotate within a preset angle range to prevent the position of the suction nozzle 300 from being uncontrollable.

The fitting portion 1120 may be provided on the upper housing 110 .
