In a further preferred embodiment shown in fig. 2 to 5, a shield 70 is provided between the end cap 20 and the atomising surface of the porous body 31, in use an atomising chamber being formed between the shield 70 and the atomising surface of the porous body 31; the shield 70 is a plastic member made of plastic material and can receive the liquid substrate seeping from the atomizing surface and the aerosol condensate falling from the atomizing surface.
As shown in fig. 7 in particular, the shutter 70 includes a first portion 71 extending in the cross-sectional direction of the outer housing 10, and a second portion 72 extending from the first portion 71 toward the end cap 20 in the axial direction of the outer housing 10; the second portion 72 abuts the end cap 20 in use to secure the shield 70 within the outer housing 10.
Further according to the preferred embodiment shown in fig. 7, the first portion 71 is provided with a through hole 711, the shape of the through hole 711 extending in a meandering manner, and the length of the through hole 711 in the extending direction is greater than the width; the through hole 711 comprises a first side wall 7111 and a second side wall 7112 which are opposite in width direction, the width W of the through hole 711 is 0.3-0.6 mm, and the roundabout extending length of the through hole 711 can be about 0.3-30 mm; further in practice, when the liquid substrate or condensate falls onto the first portion 71, a liquid film of meniscus is eventually formed between the first 7111 and the second 7112 walls within the through hole 711, on the one hand due to the surface tension of the liquid, causing it to bear and be retained on the first portion 71. And during the suction, on the one hand the air entering through the air intake 24 can enter the nebulization chamber through the liquid film breaking through the meniscus, and on the other hand the through holes 711 have a sufficient length so that the liquid film cannot completely cover the through holes 711 to keep the suction resistance of the user suction adequate and the air flow sufficient.
In practice, the second portion 72 of the shield 70 is configured as a cylinder around the air inlet aperture 24 of the end cap 20, so as to block the flow of liquid on the inner surface of the end cap 20 towards the air inlet aperture 24 on the one hand, and also to direct the air flow so that air entering through the air inlet aperture 24 can only pass through the first portion 71 to enter the nebulizing chamber on the other hand.
In a preferred embodiment, the projection of the first portion 71 in the axial direction of the outer housing 10 covers the intake hole 24, and the extension length of the through hole 711 in the thickness direction of the outer housing 10 is larger than that of the intake hole 24.

The width W of the through holes 711a is about 0.3-0.6 mm, the extending length L of the through holes 711a is larger than the width W, the length L is about 0.3-6 mm, and the waist-shaped through holes 711a uniformly arranged on the first portion 71a are more beneficial to improving the uniformity of air entering the atomizing chamber. And in practice, the liquid matrix or the condensed liquid can form a meniscus between the first side wall 7111a and the second side wall 7112a of the kidney-shaped through hole 711a opposite in the width direction, and thus cannot leak out toward the air inlet hole 24; and the air flow impact force can break away the liquid film in the process of suction, and the air flow is not influenced to enter the atomizing chamber.
The through hole 711/711a adopts a non-circular capillary hole mode, so that the problem that the whole through hole is easily covered by a liquid film due to insufficient length of the circular capillary hole is avoided; the above through-holes 711/711a having a greater extent than width may, in alternative embodiments, also be of circular, polygonal circular, or planar spiral configuration, so that they have sufficient extent that the liquid substrate or condensate does not completely cover the through-holes when they form a meniscus of liquid film within the through-holes.
In the atomizer, the shielding piece with the through hole is arranged between the end cover and the atomizing surface of the porous body, so that air can permeate while the leaked liquid matrix or condensate is received; the aerosol in the atomizing chamber is generated and output more uniformly, and the smoking taste is improved.
It should be noted that the preferred embodiments of the present invention are shown in the specification and the drawings, but not limited to the embodiments described in the specification, and further, it will be apparent to those skilled in the art that modifications and variations can be made in the above description and all such modifications and variations should fall within the scope of the appended claims.
