Description

Technical Field

[0001] The utility model relates to the technical field of atomizing cores, in particular to an atomizing core structure. Background Art

[0002] An electronic cigarette uses a heating element to heat an atomizing core, so that the e-liquid in the atomizing core is vaporized by heat into high-temperature steam. After the high-temperature steam is discharged from the electronic cigarette, it condenses into tiny liquid droplets in a smoke shape, thus forming a smoke similar to that of a traditional cigarette. The atomizing core is an important component of the electronic cigarette, and the structure of the atomizing core plays an important role in the generation of high-temperature steam and the quality of the high-temperature steam.

[0003] Currently, most traditional atomizing cores adopt a welding structure. Specifically, in the atomizing core, the heating element is welded to the conductive element or the conductive column, so that: when the conductive element or the conductive column is powered on, the conductive element or the conductive column is electrically connected to the heating element, causing the heating element to generate heat, and the e-liquid in the atomizing core is vaporized by heat into high-temperature steam, and then smoke is generated.

[0004] Since the microporous liquid guiding and storing member and the heating member of the existing atomizing core are separately arranged and need to be assembled manually, the assembly efficiency is low and the labor cost is high. Moreover, after the microporous liquid guiding and storing member and the heating member are assembled, the overall occupied space is large.

[0005] Therefore, in the patent application of the present utility model, the applicant has carefully studied an atomizing core to solve the above problems. Summary of the Utility Model

[0007] To achieve the above purpose, the present utility model adopts the following technical solutions:
