3. The atomizer for the electronic cigarette of claim 1 , wherein a sealant is further provided between the stepped column and the flange, the sealant is used to seal the connection gap between the stepped column and the flange; the edgefold abuts the flange and the protrusion.
4. The atomizer for the electronic cigarette of claim 1 , wherein the stepped column is located in the oil storage cavity, the flange abuts the stepped column after passing the protrusion, the edgefold goes through the protrusion by elastic deformation and then abuts the flange and the protrusion.
5. The atomizer for the electronic cigarette of claim 4 , wherein the edgefold is a claw-like structure composed of a plurality of elastic bodies; the inner diameter defined by the edgefold is less than the outer diameter of the protrusion or the groove; the surface of the protrusion contacting the edgefold is substantially perpendicular to the side surface of the ventilation pipe, the surface of the edgefold contacting the protrusion is substantially perpendicular to the side surface of the ventilation pipe.
6. The atomizer for the electronic cigarette of claim 4 , wherein during the assembly process, the surface that the protrusion and the edgefold contact first is an inclined surface or an arc transitional surface.
7. The atomizer for the electronic cigarette of claim 1 , further comprising a suction nozzle, the oil storage cavity enclosed by the ventilation pipe and the oil storage pipe has an opening, after the suction nozzle is connected to the ventilation pipe or/and the oil storage pipe, the opening is sealed.
8. The atomizer for the electronic cigarette of claim 7 , wherein the suction nozzle is connected to the ventilation pipe through a clamping structure, after the suction nozzle is connected to the ventilation pipe, the suction nozzle abuts against the oil storage pipe to seal the opening.
9. The atomizer for the electronic cigarette of claim 8 , further comprising a second sealing ring and a third sealing ring, the second sealing ring is located between the suction nozzle and the ventilation pipe, the second sealing ring tightly presses the suction nozzle and the ventilation pipe; the third sealing ring tightly presses the suction nozzle and the oil storage pipe.
10. The atomizer for the electronic cigarette of claim 1 ,
wherein the atomization assembly has an oil absorber, the atomization assembly has two ends, both ends of the atomization assembly are sleeved with elastic sealing sleeves, the part of the middle side surface of the atomization assembly that is not covered by the sealing sleeve is close to the oil inlet hole so as to absorb the e-liquid flowing in from the oil inlet hole; after the atomization assembly is installed in the ventilation pipe, both the sealing sleeves abut against the inner wall of the ventilation pipe.
11. The atomizer for the electronic cigarette of claim 10 , wherein each of the sealing sleeves is provided with at least one convex ring surrounding the sealing sleeve on the surface contacting the ventilation pipe.
12. The atomizer for the electronic cigarette of claim 10 , wherein the outer diameter of the portion of the oil absorber covered by the sealing sleeve is less than the outer diameter of the portion of the oil absorber that is not covered by the sealing sleeve.
13. The atomizer for the electronic cigarette of claim 10 , wherein the outer diameter of the part of the oil absorber by the oil inlet hole is close to the inner diameter of the space in which the atomization assembly is arranged in the ventilation pipe.
