Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to a cigarette cartridge and an electronic cigarette. Background Art

[0002] Electronic cigarettes are a type of consumer-grade atomizer that produces aerosols by atomizing the e-liquid for users to inhale.

[0003] In the related technology, electronic cigarettes usually consist of two parts: a cartridge and a cigarette rod. The cigarette rod is used to provide electrical energy for the atomization of the cartridge. On the market, the cartridge mainly includes atomization components and oil tanks and other structural parts. The working principle is that the oil tank supplies the atomization component with smoke oil. After the atomization component is powered, the smoke oil is atomized by the atomization component to produce aerosol.

[0004] However, since the oil tank is in direct contact with the atomizer component, and the amount of e-liquid stored in the oil tank is large, most of which are about 10 ml, and the e-liquid is in a free-flowing state inside the oil tank, the e-liquid in the oil tank is easier to flow into the atomizer component, making the atomizer component prone to e-liquid leakage, resulting in a poor user experience.
