referring to fig. 1-3, an atomizer 100 according to an embodiment of the present invention includes an oil cup 10, a bottom assembly 40, an atomizing core 30, a nozzle assembly 20, and an air guide assembly 50.

In this way, when a user sucks air towards the air suction hole 211, the airflow outside the atomizer 100 enters the atomizing passage 34 of the atomizing core 30 from the first air inlet passage 42, mixes with the aerosol formed by heating and atomizing the atomizing core 30 to form a mixed airflow, and then flows into the air suction hole 211 through the airflow passage 51; meanwhile, the airflow outside the atomizer 100 enters the airflow channel 51 from the second air inlet channel 23 through the second air passing hole 531, the annular cavity 54 and the first air passing hole 521 in sequence, and under the negative pressure action in the user suction process, the airflow flowing in from the first air passing hole 521 flows towards the air suction hole 211 along the inner wall of the airflow channel 51, so that an air curtain is formed to prevent the high-temperature mixed airflow from contacting the inner wall of the airflow channel 51, the temperature of the mixed airflow is reduced, and the condensate formed by the mixed airflow on the inner wall of the airflow channel 51 is reduced, thereby improving the user suction experience, and simultaneously reducing the liquid leakage caused by the accumulation of the condensate.

It should be noted that the aperture of the airflow channel 51 is the same as or smaller than the aperture of the air suction hole 211, so as to ensure that the mixed airflow and the air curtain can stably enter the air suction hole 211, that is, the airflow entering the atomizing channel 34 from the second air inlet channel 23 can also play a role of the air curtain after entering the air suction hole 211, so as to block the contact between the atomized airflow and the inner wall of the air suction hole 211, so that the mixed airflow contacts the inner wall of the air suction hole 211 as little as possible, and the condensate formed on the inner wall of the air suction hole 211 is reduced.

It should be understood that the present embodiment is illustrated with the air guide assembly 50 disposed between the oil cup 10 and the suction nozzle assembly 20; in other embodiments, the air guide assembly 50 may be directly mounted on the top end of the oil cup 10, and the air flow channel 51 of the air guide assembly 50 is communicated with the end of the atomizing channel 34 far from the bottom assembly 50, and the nozzle assembly 20 is omitted, that is, the outer wall of the air guide outer tube 53 is directly configured into the shape of a nozzle, and the function of reducing the condensate formed by the mixed air flow on the air flow channel 34 can also be achieved, of course, one end of the air guide assembly 50 of the present application may also be inserted into a nozzle hole at the top of a conventional atomizer to be communicated with the atomizing channel thereof, and the other end protrudes from the nozzle Kong Waigong for suction, so as to be used as an accessory of the conventional atomizer, and therefore, the application of the air guide assembly 50 of the present invention is not limited to the atomizer 100 with the nozzle assembly 20.

The second air passing holes 531 are disposed at an end of the air guide outer tube 53 away from the atomizing core 30, so that the air flow entering the second air inlet channel 23 can flow from top to bottom toward the first air passing holes 521 after entering the annular cavity 54 through the second air passing holes 531, so that the air flow can flow from each first air passing hole 521 into the atomizing channel 34 relatively uniformly in the annular cavity 54, thereby forming an air curtain for blocking the mixed air flow from contacting the inner wall of the atomizing channel 34.

In a specific embodiment, as shown in fig. 4, in this embodiment, both the air guide inner tube 52 and the air guide outer tube 53 are tube bodies with two open ends, the outer wall of one end of the air guide inner tube 52 radially protrudes to form a first annular flange 522, and the first annular flange 522 tightly abuts against the inner wall of the air guide outer tube 53; the inner wall of one end of the air guide outer tube 53, which is far away from the first annular flange 522, is radially protruded to form a second annular flange 532, and the second annular flange 532 tightly abuts against the outer wall of the air guide inner tube 52, so that the air guide inner tube 52, the air guide outer tube 53, the first annular flange 522 and the second annular flange 532 jointly enclose the annular cavity 54, that is, the air guide inner tube 52 is positioned in the air guide outer tube 53 at intervals under the action of the first annular flange 522 and the second annular flange 532, so as to form the annular cavity 54 with uniform wall thickness in the gap between the air guide inner tube 52 and the air guide outer tube 53, and the upper end and the lower end of the annular cavity 54 are respectively sealed and blocked by the first annular flange 522 and the second annular flange 532.
