The base 30 is provided with an air inlet 31 and an electrode hole, a conductive electrode 33 is inserted in the electrode hole, one end of the conductive electrode 33 is exposed outside the shell of the atomizer 100 so as to be electrically connected with a power supply mechanism matched with the atomizer 100, and the other end of the conductive electrode 33 extends to an atomizing surface 412 of the liquid guide element 41 so as to be electrically connected with a heating element 42 of the atomizing surface 412, so that electric energy required for heating can be provided for the heating element 42 of the atomizer 100 through the power supply mechanism of the conductive electrode 33. It will be appreciated that the conductive electrode 33 comprises two electrode posts which serve as positive and negative poles for conducting current, the ends of the conductive electrode 33 abutting against the atomizing element 40 to support it so that it is positioned in the first housing chamber 212 described above.

With continued reference to fig. 3, the base 30 supports a first sealing member 50, where the first sealing member 50 may be a soft rubber member such as silica gel or rubber, and the first sealing member 50 is in interference fit with an inner wall of the liquid storage portion 20 so as to seal the distal end 23 of the liquid storage portion 20, and the first sealing member 50 is disposed opposite to the atomizing element 40 and defines an atomizing chamber 413, and aerosol generated by the atomizing element 40 heating the atomized liquid matrix is released therefrom, and the first sealing member 50 is located between the air inlet 31 and the atomizing chamber 413.

When the atomizer 100 is in operation, the external cold air enters the atomizing chamber 413 and is mixed with the high-temperature aerosol in the atomizing chamber 413, the high-temperature aerosol is condensed to form condensed liquid drops, and the condensed liquid drops fall off when meeting the external cold air, so that the condensate drops can be prevented from leaking out from the distal end 23 of the liquid storage part 20 by the seal formed by the first seal member 50.

The air inlet hole 31 provides an air flow inlet for external air into the atomizer 100, the first sealing member 50 is provided with a first air inlet hole 51, the first air inlet hole 51 is communicated with the air inlet hole 31 and the atomization chamber 314, so that when the atomizer 100 works, negative pressure is generated inside the atomization chamber 413, the external air is caused to flow into the atomization chamber 413 through the air inlet hole 31 and the first air inlet hole 51, then aerosol in the atomization chamber 413 is carried to flow into the first air flow channel 24 and the second air flow channel 25, then flows into the suction nozzle 10 through the first air flow channel 24 and the second air flow channel 25, and finally, the air flows out of the atomizer 100 through the air outlet hole 11 of the suction nozzle 10, so that an air path of the atomizer 100 is formed, as shown by an arrow route R in fig. 3.

With continued reference to fig. 3, further, the first sealing member 50 is further provided with a second air inlet hole 52, the projection of the atomizing element 40 on the first sealing member 50 covers the first air inlet hole 51 and avoids the second air inlet hole 52, one end of the second air inlet hole 52 is communicated with the external air through the air inlet 31 or directly communicated with the external air, and the other end is communicated with the atomizing chamber 413, so that the external air can also enter the atomizing chamber 413 through the second air inlet hole 52. As the atomizer 100 is used for a long time, the condensate is excessively accumulated and can block the first air inlet hole 51, so that the air path of the atomizer 100 is blocked, no negative pressure is generated in the atomization chamber 314, and the atomizer 100 cannot work. By providing the second air inlet hole 52, since the projection of the atomizing element 40 on the first sealing member 50 covers the first air inlet hole 51 and avoids the second air inlet hole 52, when the first air inlet hole 51 is blocked, the second air inlet hole 52 is not blocked, and external air can still enter the atomizing chamber 413 through the second air inlet hole 52, the atomizing chamber 413 can still generate negative pressure and trigger the atomizer 100 to work, so that the heating element 42 starts to heat, and the condensate blocking the first air inlet hole 51 is further heated and gradually diluted by the heat generated by the heating element 42, so that the first air inlet hole 51 can be turned on again.

In some embodiments, as shown in fig. 3, the first air inlet hole 51 is located in the central region of the atomizing chamber 413, and the second air inlet hole 52 is offset from the central region of the atomizing chamber 413, so that the first air inlet hole 51 may be used as a main air inlet hole of the atomizer 100, and the second air inlet hole 52 may be used as an auxiliary air inlet hole of the atomizer 100, and after the external air enters the atomizer through the air inlet 31, the external air enters the atomizing chamber 413 mainly through the first air inlet hole 51.

Further in some embodiments, as shown in fig. 7, the aperture of the first air inlet hole 51 is larger than that of the second air inlet hole 52, and since the projection of the atomizing element 40 on the first sealing member 50 covers the first air inlet hole 51 and avoids the second air inlet hole 52, the external air mainly enters the atomizing chamber through the first air inlet hole 51 with a larger aperture, so that the negative pressure induction of the atomizing chamber 413 can be more sensitive.

In the preferred embodiment shown in fig. 3 and 7, the first seal 50 has oppositely disposed first and second surfaces 510, 520, the first surface 510 facing the atomizing element 40, and the first air inlet aperture 51 extending from the second surface 520 to the first surface 510.

In some embodiments, to reduce the difficulty of designing the mold of the second air intake hole 52 on the second sealing member 50, the second air intake hole 52 is constructed in a non-straight hole form, and to facilitate the smooth passage of the external air through the second air intake hole 52, the aperture at the minimum of the second air intake hole 52 is not less than 0.5mm.

In the preferred embodiment illustrated in fig. 8, the second inlet aperture 52 includes a first portion 521 and a second portion 522, with outside air entering the first inlet aperture 52 through the first portion 521 and escaping the second inlet aperture 52 from the second portion 522 further into the nebulization chamber 413, the aperture of the first portion 521 being larger than the aperture of the second portion 522. Alternatively, in some embodiments, the second air intake aperture 52 may be configured as a tapered aperture, the second air intake aperture 52 having an air intake end and an air outlet end disposed opposite each other, the aperture of the second air intake aperture 52 being configured to taper from the air intake end to the air outlet end.

In an exemplary embodiment, the atomizer 100 and the power supply mechanism 200 may be detachably connected by a magnetic connection, which may give the user a better use experience.
