[0002] Electronic cigarette atomizers heat liquid and convert it into vapor to simulate the feel and taste of traditional cigarettes. Users can inhale the resulting vapor into their mouths through the mouthpiece to simulate the feeling of smoking. Compared to traditional cigarettes, electronic cigarettes have some advantages. For example, they do not cause harm to people around them because they do not have the smoke and second-hand smoke produced by combustion.

The oil separator 7 plays a role of sealing and partitioning.

[0040] The cavity between the oil separator 7 and the oil bin upper cover 6 forms an oil storage chamber 19. Meanwhile, the cavity between the oil separator 7 and the oil bin bottom cover 5 forms an atomization chamber 20. One is used to store the smoke oil, and the other realizes atomization of the smoke oil. The two are connected.

[0041] An oil storage cotton 17 is arranged inside the oil bin bottom cover 5, and a heating wire 10 is arranged on the upper end of the oil storage cotton 17.

[0057] The horizontally placed heating wire 10 is easy to assemble, and the heating wire 10 will not deform or tear, thereby reducing the material cost of the electronic cigarette atomizer and the labor cost of the assembly process;

[0058] The area of ​​the horizontally placed heating wire 10 can be enlarged, the working atomization area is increased, and the evaporation amount of the e-liquid and the atomization efficiency are increased;
