The closure member 3 is used to block the air inlet hole 43 to prevent the atomizer from leaking atomized liquid and/or condensed liquid through the air inlet channel 4 before the atomizer is activated. The closure member 3 only needs to be slid from the first position to the second position, and the closure member 3 can slide into the second vertical air channel 42, and the closure member 3 is staggered with the air inlet hole 43. At this time, the closure member 3 is closed. The sealing member 3 releases the blocking effect on the air inlet 43, and the external air can be introduced into the atomizing channel 15 through the air inlet 43 and the first vertical air channel 41. In addition, since the sealing member 3 is located in the second vertical air channel 42, the second vertical air channel 42 can be closed by the sealing member 3, which can prevent the atomized liquid and/or condensed liquid gathered and converged in the atomizing channel 15 from flowing out directly through the second vertical air channel 42 under the action of its own gravity, which is conducive to avoiding the leakage of the atomizer through the air inlet channel 4 and improving the user experience.

Please further refer to FIG. 2 and FIG. 4 . In some embodiments, the atomizer further includes a porous flow-limiting member 6 disposed in the liquid storage chamber 16. When the atomizer is used, the atomized liquid in the liquid storage chamber 16 can be adsorbed and/or stored in the porous flow-limiting member 6, and the atomized liquid in the porous flow-limiting member 6 is transmitted to the atomizing core 2 in the atomizing channel 15 via the liquid guide hole. Since the porous structure of the porous flow-limiting member 6 has a certain liquid locking ability, the atomized liquid can be bound and stored in the porous flow-limiting member 6, and the capillary structure of the porous flow-limiting member 6 can slowly and evenly transmit the adsorbed and/or stored atomized liquid to the atomizing core 2 in the atomizing channel 15 via the liquid guide hole, so as to limit and slow down the liquid supply rate from the liquid storage chamber 16 to the atomizing core 2 in the atomizing channel 15, and effectively prevent the atomized liquid in the liquid storage chamber 16 from directly flowing into the atomizing channel 15 via the liquid guide hole, thereby helping to reduce the risk of leakage.

Please further refer to FIG. 2 and FIG. 4 . In some embodiments, the porous flow limiting member 6 fills the liquid storage cavity 16, and the porous flow limiting member 6 covers the liquid guide hole, thereby increasing the atomized liquid in the liquid storage cavity 16 passing through the liquid guide hole. The flow resistance transmitted to the atomization channel 15 is increased, thereby enhancing the effect of preventing liquid leakage.

Please further refer to Figures 2 and 4. In some embodiments, the porous flow limiting member 6 is columnar, and the porous flow limiting member 6 is provided with a sleeve hole along the axial direction. The atomizing tube 13 is inserted into the sleeve hole of the porous flow limiting member 6. On the one hand, the porous flow limiting member 6 enhances the uniform stability of the atomized liquid transmitted by the atomizing liquid, and on the other hand, it is conducive to improving the anti-leakage effect. It can be understood that in some specific embodiments, the porous flow limiting member 6 is at least one of porous cotton, porous sponge, porous glass fiber, porous ceramic and porous graphite.
