It is understood that in other embodiments, the microporous structure 60 may be integrally formed with the base 20 or the base 30, which may be injection molded. Of course, it can be detachably connected to the base 20 or the base 30. It is understood that in other embodiments, the plate body 61 can be omitted, the plurality of micro holes 62 can be directly formed on the base body of the base 30, or the plurality of micro holes 62 can be directly formed on the base 20.

Further, in some embodiments, the plurality of micro-holes 62 may be arranged on the air intake hole 21, and in particular, in some embodiments, may cover the entire air intake hole 21, thereby making the air flow more sufficient. In addition, in some embodiments, when the atomizer 100 is installed in the power supply housing 201, and when the magnet 204 in the power supply housing 201 blocks the second gas inlet 311, gas can also enter the second gas inlet 311 through the micro holes 62 near the magnet 204, thereby ensuring the continuity of the gas inlet. In some embodiments, the pore diameter of the micropores 62 of the microporous structure 60 may be 0.1-0.5mm, and the micropores 62 with the pore diameter may enable the inner sides of the micropores 62 to have capillary force on the nebulizable medium, so that the nebulizable medium may form a tension film on the surface of the micropores 62, thereby preventing liquid leakage.

Further, in some embodiments, the atomizer 100 may also include a start tube 70; the starting tube 70 can be inserted into the second air inlet 311, and a certain gap is left between the starting tube and the end surface of the air inlet end of the second air inlet 311, so that the airflow entering the atomizer 100 from the microporous structure 60 can be more sufficient. The starter tube 70 may include an inlet end 71 and an outlet end 72; the air inlet 71 may be disposed opposite to the microporous structure 60, and a space may be left between the air inlet and the microporous structure 60 for communicating with the air inlet channel, so as to facilitate the gas to enter the atomizing chamber 33. The starting tube 70 can be arranged higher than the seat body 11, and the aperture of the second air inlet 311 can be reduced by arranging the starting tube 70, so as to further prevent liquid leakage and prevent liquid from flowing into the pneumatic switch 203 from the second air inlet 311.

Further, in some embodiments, the atomizer 100 further comprises a seal 80; the sealing member 80 may be disposed at a lower portion of the liquid storage cavity 13, may be sleeved on the atomizing support 40, and may be used to seal a gap between the atomizing support 40 and the housing 10, so as to prevent liquid from leaking out toward the gap. This seal 80 may in some embodiments be a sealing sleeve, in particular it may be a silicone sleeve or a rubber sleeve. It will be appreciated that in other embodiments, it may not be limited to a silicone sleeve or a rubber sleeve.

Further, in some embodiments, the suction nozzle 90 can be sleeved on the mounting portion 112 of the housing 11, and an opening can be formed thereon, and the opening can be communicated with the air outlet channel 13 to facilitate air output. The mouthpiece 90 may be flat cylindrical. It will be appreciated that in other embodiments, the suction nozzle 90 may not be limited to being flat, cylindrical.

It is to be understood that the foregoing examples merely represent preferred embodiments of the present invention, and that the description thereof is more specific and detailed, but not intended to limit the scope of the invention; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
