Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, specifically to an open-type e-cigarette cartridge with an independent airway. Background Technology

[0002] The cartridge, as one of the core components of an e-cigarette, is the part that contains e-liquid (also known as e-cigarette liquid) and heats it to produce an aerosol for the user to inhale;

[0003] According to a patent published on the China Patent Network, the patent title is "Tobacco Cartridge," and the patent application number is 202420213114.3. It includes a tobacco cartridge body with an inner cavity for filling tobacco. One end of the cartridge body has a sealed end, and the other end is an open end. The connection between the cartridge body and the sealed end is a rounded corner structure. The sealed end includes an outer ring connecting part and an inner ring heating part. The inner ring heating part is recessed towards the inside of the cartridge body and has multiple micro-holes. This invention effectively avoids the problem of micro-hole blockage caused by complete adhesion, thereby improving heating efficiency and providing advantages. The rapid increase in internal temperature of the e-liquid cartridge improves heating efficiency and extends battery life in e-cigarettes or other heating devices. However, after repeated refills and use, the accumulated condensation and e-liquid from repeated refills can cause the absorbent cotton at the bottom of the cartridge to become saturated and overflow from the air intake, necessitating the disposal of the entire cartridge. This results in high user costs, significant environmental pollution, and, when refilling the cartridge, prolonged inactivity, or excessive condensation, e-liquid can easily leak from the central air intake, directly onto the outside of the cartridge, negatively impacting the user experience.

[0004] Therefore, the design of the e-liquid cartridges needs to be modified to effectively prevent the e-liquid from easily leaking out of the air intake and affecting the user experience. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide an open-type e-liquid cartridge with an independent airflow channel. This independent airflow channel prevents e-liquid from flowing out of the air intake, and the e-liquid cartridge's oil tank is reusable and replaceable, thus solving the problem of e-liquid easily flowing out of the air intake and affecting the user experience.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an open-type e-cigarette cartridge with an independent airway, comprising a cartridge assembly;
