In the illustrated embodiment, the boss 430 has a top surface 431 and a side surface 432. The side surface 432 extends vertically and is connected to the top surface 431. The top surface 431 and the fixing surface 420 are spaced apart from each other in the vertical direction. The top surface 431 faces upward. The side surface 432 is connected between the top surface 431 and the fixing surface 420. The air inlet channel 440 includes the air inlet 441 and an output groove 442. The air inlet 441 is in fluid communication with the outside atmosphere. The output groove 442 is in fluid communication with the air guiding cavity 410 and the air inlet 441. The output groove 442 extends through the side surface 432 and the top surface 431. The output port 442a is located on the output groove 442. Specifically, when the sealing member 300 is provided on the base 400, the mounting surface 310 of the sealing member 300 is attached to and abuts against the top surface 431 of the protruding post 430, such that the mounting surface 310 blocks an opening of the output groove 442 on the top surface 431. In this case, the opening of the output groove 442 on the side surface 432 can form the output port 442a.
In other embodiments, for example, the mounting surface 310 may be spaced apart from the top surface 431. That is, the mounting surface 310 does not cover the opening of the output groove 442 on the top surface 431. In this case, the openings of the output groove 442 on the top surface 431 and on the side surface 432 cooperatively form the output port 442a. For another example, the output groove 442 may only extend through the top surface 431. The opening of the output groove 442 on the top surface 431 forms the output port 442a. Since the top surface 431 is a horizontal surface, the output port 442a is arranged horizontally. For another example, the output groove 442 may only extend through the side surface 432, and the opening of the output groove 442 on the side surface 432 forms the output port 442a. Since the side surface 432 is a vertical surface, the output port 442a is arranged vertically.

When the user inhales at the nozzle 121a, the outside air flows through the air inlet channel 440, the air guiding cavity 410, and the directing hole 340 successively and enters the atomizing cavity 350 to carry the aerosol. Then, the air carrying the aerosol can flow through the guiding passage 212, the air guiding hole 211, and the inhaling hole 121 successively and reaches the nozzle 121a, such that the aerosol is inhaled by the user. The dashed arrows in
Generally, when the atomizer 10 is out of use, the aerosol remained in the atomizing cavity 350 can be liquefied to form a condensate. While a seeping liquid can be formed on the atomizing core 510, and the seeping liquid can drop from the atomizing core 510. The seeping liquid and the condensate together form the leakage liquid. Since the sealing member 300 includes a boss 330 located in the atomizing cavity 350, and the boss 330 protrudes from the connecting surface 320. Apart of the leakage liquid can be attached to the connecting surface 320. That is, the leakage liquid can be stored in a recessed space of the atomizing cavity 350 located on the edge of the boss 330. The directing hole 340 extends through the free end surface 331 of the boss 330 and is in fluid communication with the atomizing cavity 350, such that the leakage liquid stored in the recessed space is difficult to reach the free end surface 331, thus preventing the leakage liquid from entering the directing hole 340, and ensuring that the recessed space in the atomizing cavity 350 can effectively store the leakage liquid.
Sometimes a part of the seeping liquid will drop directly into the directing hole 340, and some aerosol can enter the directing hole 340 from the atomizing cavity 350. This part of the aerosol can also be liquefied in the directing hole 340 to form the condensate. In short, a part of the leakage liquid cannot be stored in the recessed space, but can be transferred from the directing hole 340 to the flow guiding member 360 via the input port 341, such that the leakage liquid on the flow guiding member 360 can eventually drop onto the liquid absorbing member 520. Since the flow guiding member 360 is offset from the output port 442a in the horizontal direction, the leakage liquid dropped from the flow guiding member 360 cannot fall into the output port 442a. As such, the leakage liquid is prevented from leaking out from the atomizer 10 via the air inlet channel 440 to enter the power supply, thus preventing the leakage liquid from corroding the power supply or even causing the power supply to explode, thereby improving the service life and safety of the power supply. In addition, the input port 341 is also offset from the output port 442a in the horizontal direction. Even if a part of the leakage liquid cannot enter the flow guiding member 360 and drops directly from the input port 341, it can effectively prevent the leakage liquid dropped from the input port 341 from directly entering the output port 442a, thereby effectively avoiding the leakage liquid from leaking out of the atomizer 10 via the air inlet channel 440. Since the side surface 432 can be vertically connected to the top surface 431, when the output port 442a is located above the side surface 432 that is vertically arranged, the output port 442a can be arranged vertically. Even if the output port 442a is not offset from the input port 341, when the leakage liquid drops from the input port 341, the dropped leakage liquid is difficult to enter the output port 442a.
After the flow guiding member 360 guides the leakage liquid into the air guiding cavity 410, the leakage liquid can be stored in the recessed space at the edge of the protruding post 430. Since a certain distance is kept between the output port 442a and the fixing surface 420, that is, the height of the output port 442a is higher than that of the fixing surface 420, it can ensure that the leakage liquid in the recessed space cannot reach the output port 442a, thus avoiding the leakage liquid from leaking via the air inlet channel 440. Further, the liquid absorbing member 520 can be fixed on the fixing surface 420 of the base 400. The leakage liquid on the flow guiding member 360 can be directly input to the liquid absorbing member 520. Due to the absorption and restraining effect of the liquid absorbing member 520, it can effectively prevent the liquid from flowing freely in the air guiding cavity 410, thereby preventing the liquid level in the recessed space in the air guiding cavity 410 from reaching the output port 442a.
When the user inhales at the nozzle 121a, subjected to the negative pressure, the condensate and non-liquefied suspended droplets in the atomizing cavity 350 can flow into the guiding passage 212. In this case, due to the recessed structures such as the first groove 213c, the second groove 215a, the third groove 213d and the micro-groove 216a, the recessed structures can obstruct and adsorb the leakage liquid formed by the condensate and suspended droplets, such that the leakage liquid is received in the recessed structures and is difficult to enter the inhaling passage 11, thus preventing the user from inhaling the leakage liquid into the mouth. In addition, since the annular gap 124 is formed between the tip portion 123 of the central post 120 and the first inner surface 211a, even if the leakage liquid enters the air guiding hole 211 from the guiding passage 212, the annular gap 124 can receive and obstruct the leakage liquid, thus preventing the leakage liquid from entering the nozzle 121a to be inhaled by the user. Furthermore, since the receiving groove 122a is formed on the second surface of the center post 120, even if the leakage liquid enters the air inlet 441 via the air guiding hole 211, the receiving groove 122a can receive and obstruct the leakage liquid to prevent the leakage liquid from entering the nozzle 121a to be inhaled by the user. Therefore, due to the triple obstruction of the recessed structures on the inner wall surface 213, the annular gap 124, and the receiving groove 122a, the leakage liquid can be effectively prevented from being inhaled by the user.
When the atomizer 10 is tilted or inverted, the nozzle 121a faces downward, and the condensate in the atomizing cavity 350 and the seeping liquid dropping from the atomizing core 510 into the atomizing cavity 350 will form the leakage liquid. Under the action of gravity, the leakage liquid will flow from the atomizing cavity 350 into the guiding passage 212. Based on the similar principle, due to the triple obstruction of the recessed structures on the inner wall surface 213, the annular gap 124, and the receiving groove 122a, the leakage liquid can be effectively prevented from flowing out of the atomizer 10 via the nozzle 121a.
Accordingly, the atomizer 10 can not only effectively prevent the leakage liquid from leaking out of the atomizer 10 via the air inlet channel 440, preventing the leakage liquid from corroding the power supply or causing the power supply to explode, but also can effectively prevent the leakage liquid from leaking out of the atomizer 10 via the nozzle 121a of the air inlet channel 11. If the air inlet channel 440, the air guiding cavity 410, the liquid directing passage 12, the guiding passage 212, and the inhaling passage 11 are regarded as an airflow passage through which the outside air flows, the atomizer 10 can prevent the leakage liquid from leaking out of the atomizer 10 via the upper and lower ends of the airflow passage. In addition, it can prevent the condensate and suspended droplets from being inhaled by the user during inhalation, which can improve the user's inhaling experience.

To simplify the description, not all possible combinations of the technical features in the above embodiments are described. However, all of the combinations of these technical features should be considered as being fallen within the scope of the present disclosure, as long as such combinations do not contradict with each other.

However, it should not be understood as a limitation to the patent scope of the present disclosure. It should be noted that, a person of ordinary skill in the art may further make some variations and improvements without departing from the concept of the present disclosure, and the variations and improvements falls in the protection scope of the present disclosure.
