And when the user sucks, part of aerosol enters the atomizing cavity 412, the convex structure or the groove structure is used for increasing the adsorption surface area when the condensate is adsorbed, so as to collect the condensate in the sucking and atomizing process, and avoid the condensate from leaking into the battery rod to damage components.

When a user sucks, the atomized liquid in the liquid storage cavity 13 is absorbed by the heating component 30 and heated for atomization, so that negative pressure is formed in the liquid storage cavity 13, and when external air is mixed with aerosol, a part of gas enters the liquid storage cavity 13 from the formed air return channel 29 and through the liquid inlet channel 22, so that the air pressure in the liquid storage cavity 13 is balanced, and the situation of poor oil guide is avoided.

In this way, the outside air enters the atomizing chamber 412, mixes with the aerosol, enters the through-air chamber 27 through the through-groove 28, and is then sucked by the user through the air duct 12.

5. The atomizer of claim 3 wherein said atomizing chamber has arcuate surfaces at each end thereof projecting toward said central axis, said arcuate surfaces being provided with a plurality of said strip-shaped projections.

6. The atomizer of claim 1 wherein the spacing between a plurality of said raised structures or recessed structures is less than 1mm.

7. The atomizer of claim 1 wherein a top surface of said base is recessed to form a reservoir for storing condensate.

8. The atomizer of claim 1 wherein a lower end of said bracket is disposed to a top end of said base to clamp said heat generating component between said bracket and said base.

9. The atomizer of claim 8 wherein said bracket includes a top wall and a side wall extending along a periphery of said top wall in a downwardly convex manner, said side wall being disposed around an upper end of said base, said liquid inlet passage extending vertically therethrough and being disposed in said top wall, a top surface of said oil guide being in abutment with a bottom surface of said top wall.

10. The atomizer of claim 9 wherein said number of said liquid inlet passages is two, and said bottom surface of said top wall is recessed to form a communication groove communicating between said liquid inlet passages, and a top surface of said communication groove is disposed in a gradually downwardly inclined extending manner in a direction approaching a center of said communication groove.

11. The atomizer of claim 9 wherein said top wall has a mounting location formed in a central portion of a top surface thereof, said mounting location being in abutting communication with an air duct disposed in said cup, an air passing chamber being provided in a bottom portion thereof, said side wall being provided with a through slot extending through an inner and outer surface thereof, a lower end of said through slot extending into communication with said atomizing chamber, and an upper end extending into communication with said air passing chamber.

12. The atomizer of claim 11 wherein a lower end of said through slot extends beyond a bottom end of said side wall, and wherein a side of said base is provided with a baffle extending into said through slot.

13. The atomizer of claim 1 wherein said oil guide body and said heating element are sheet-like, said heating element comprising two fixing portions and an atomizing portion connected in series between said two fixing portions, the tips of said two electrodes being respectively abutted to said two fixing portions.

14. The atomizer of claim 13 wherein said heat generating body further comprises annular connecting portions, said number of atomizing portions is two, two of said atomizing portions are symmetrically connected to both ends of said annular connecting portions, and one end of said atomizing portion remote from said annular connecting portions is connected to said fixing portion.

15. A nebulizer as claimed in claim 13 or 14, wherein the nebulizing portion is in the form of a mesh, stripe, S-shape, fold line, wave, zigzag, spiral, circle or rectangle.

16. A nebulizer as claimed in claim 13 or 14, wherein the resistance of the nebulizing portion is greater than the resistance of the securing portion.

17. The nebulizer of claim 14, wherein the resistance of the nebulizing portion is greater than the resistance of the annular connection portion.

18. The atomizer of claim 13 wherein said heat generating assembly further comprises a support body stacked to said base top end, said heat generating body being sandwiched and positioned between said support body and said oil guide body; the support body is provided with a clearance hole corresponding to the atomization part, and the clearance hole is correspondingly communicated with the atomization cavity at the top end of the base; mounting holes are respectively formed in two ends of the support body, and the top ends of the two electrodes penetrate through the two mounting holes to be abutted to the two fixing parts.

19. The atomizer of claim 18 wherein said support is a dense ceramic member, a silicone member, a metal member having an electrically nonconductive outer surface, or an electrically conductive member having an insulating layer disposed on a top surface thereof.
