Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to a cigarette cartridge structure with replaceable oil-absorbing cotton. Background Art

[0002] An electronic cigarette is an electronic device that heats and atomizes the oil to form a vapor aerosol for users to consume. Usually, electronic cigarettes include integrated electronic cigarettes and split electronic cigarettes. Integrated electronic cigarettes are disposable electronic cigarettes in which the cigarette rod shell and the mouthpiece are crimped by a machine and cannot be disassembled. The split electronic cigarette is also called a cartridge-changing electronic cigarette, which consists of a cartridge part that integrates the mouthpiece, oil storage tank, atomization core and atomization channel, and a main unit part that integrates the control panel, microphone sensor and battery. The upper end of the main unit is provided with a plug-in cavity for plugging in the cartridge part, and the cartridge part is electrically connected to the main unit part. The main unit part of the cartridge-changing electronic cigarette can be used repeatedly. After the oil in the cartridge is used up, a new cartridge can be replaced. However, the existing cartridge structure has a common defect, that is, after the cartridge is powered on, the atomization channel will have incompletely discharged steam aerosol smoke that cools down to form a condensed oil-liquid mixture that is retained on the wall of the atomization channel. When the accumulated oil-liquid mixture reaches a certain level, it will be sucked into the user's mouth along the atomization channel, or flow into the plug-in cavity, which will bring a bad user experience and also affect the service life of the electronic cigarette.
