[0002] As consumers' health awareness gradually increases, the consumption demand and market size of electronic atomizers, as a substitute for traditional cigarettes, are expanding year by year, and electronic atomizers are also sought after by many consumers. At present, the connection between the atomizer (i.e., the cigarette cartridge) and the main control body (i.e., the cigarette rod) used in electronic atomizers mostly adopts point contact connection, and the atomization method mostly adopts direct heating of resistance wire for atomization.

[0003] The point contact connection between the atomizer and the main control body of the atomizer is prone to the following problems: 1. The point contact connection point has high production precision requirements; 2. It is easy to have the connection point misalignment and poor contact phenomenon; 3. The contact point is worn and aged due to long-term use, resulting in poor contact at the site, thus affecting the quality of the product and the customer experience. In addition, the common atomizers in the prior art mostly use resistance wire heating to atomize the liquid, which is easy to cause the atomizer core to become sticky, the heating wire to age, and the atomization volume to be low.
