Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to an electronic cigarette cartridge and an electronic cigarette provided with an anti-leakage oil structure. Background Art

[0002] The electronic cigarette mainly includes a shell, an oil storage chamber arranged in the shell, an atomization component arranged in the oil storage chamber, a control panel, a microphone sensor, and a battery. The oil storage method in the oil storage chamber mainly includes using integrated oil storage cotton to pre-absorb the oil for oil storage, and the other is to directly inject the oil into the oil storage chamber. As for the integrated oil storage cotton for oil storage, the oil is soaked in the integrated cotton for a long time, and the composition of the oil will affect the integrated cotton. When the atomization is heated, the heat is transferred to the integrated oil storage cotton, which is easy to affect the oil in a high temperature environment, resulting in affecting the taste. Therefore, in terms of the atomization taste, the electronic cigarette that directly injects the oil has less impact on the oil, and it is easy to maintain a relatively consistent taste during use. Existing electronic cigarette products that directly store oil are usually cartridge-changing electronic cigarettes, that is, they include replaceable cartridges and battery rod mainframes. The atomization channel composed of an atomizer core connected to the lower end of the suction nozzle of the existing cigarette cartridge usually has an air intake hole at the lower end. When using the electronic cigarette, the smoke aerosol vapor formed by the atomizer core atomizing the smoke oil is output from the atomization channel. At the moment of stopping inhalation, the smoke aerosol vapor in the atomization channel will cool to form condensate, which will flow down from the air intake hole and leak out from the air intake hole of the cigarette cartridge, affecting the use of the electronic cigarette.

Through the three pins of the common positive pin, the first negative pin, and the second negative pin, power is supplied to the common positive pin and the first negative pin, or the common positive pin and the second negative pin, or the common positive pin, the first negative pin, and the second negative pin are simultaneously powered on, so that any single mesh heating wire works alone, or the double-mesh heating wires work simultaneously, in order to achieve the adjustment of different atomization effects and meet different tastes.
