Description

A kind of cartridge and electronic cigarette

technical field

The invention relates to the technical field of electronic cigarettes, in particular to a cartridge and an electronic cigarette.

Background technique

Traditional cigarettes are harmful to human health, and electronic cigarettes have emerged as a substitute. The Chinese patent document whose publication number is CN203424292U discloses an atomizing device, which includes a heating wire assembly composed of a heating wire, a first oil guide rope and an electronic wire, and a ventilation tube, and the ventilation tube has a function for accommodating the heating wire. The assembly hole of the component also includes a second oil guide rope arranged in the assembly hole side by side with the first oil guide rope and in contact with the heating wire.

The Chinese patent document with publication number CN203913377U discloses an integrated disposable electronic cigarette, including an integrated hollow cigarette casing, wherein the middle side wall is provided with a radial first air intake through hole, and the first air intake through hole is directed toward the cigarette butt. The direction part is the battery accommodating cavity, and the direction towards the cigarette holder is the accommodating cavity of the atomizing device; the casing is sequentially provided with a luminous body, a battery, a hollow fixing seat and an atomizing device from the cigarette butt to the cigarette holder, and the atomizing device includes e-liquid cotton, U-shaped Oil guide rope, heating wire, fiber tube and hollow rubber cover.

The Chinese patent document with publication number CN204232305U discloses an electronic cigarette, the electronic cigarette includes an atomizer and a battery assembly, the atomizer includes an oil storage assembly, a suction nozzle arranged at one end of the oil storage assembly, and axially sleeved on the An air guide tube in the oil storage assembly, and an atomization assembly detachably inserted in one end of the oil storage assembly away from the suction nozzle, the atomization assembly includes an atomization seat inserted into the oil storage assembly, inserted in one end of the atomization seat The glass fiber tube, the atomizing electrode assembly inserted at the other end of the atomization seat and used for electrical connection with the battery assembly, and at least one group of heating wire assemblies inserted in the glass fiber tube, the heating wire assembly includes an oil guide rope and The heating wire is wound on the oil guide rope and is electrically connected to the atomizing electrode assembly. The end of the oil guide rope adjacent to the suction nozzle is the fixed end, and the other end is the free end. The fixed end passes through the glass fiber tube and is clamped in the fog. The end or side wall of the anvil is used for absorbing smoke oil from the oil storage cavity, and the free end is accommodated in the glass fiber tube and extends along the axial direction of the glass fiber tube.

It can be found that the current method for atomizing e-liquid on the market is basically that the heating wire directly heats the oil-guiding rope infiltrated with e-liquid. The oil guide rope has been in a state of e-liquid infiltration. As the calorific value increases, the oil guiding rate of the oil guiding rope does not keep up, and the temperature of the heating wire assembly will increase. When the temperature reaches a certain level, the oil guiding rope will deteriorate at high temperature, and the smoke oil will burn at high temperature. There will be a burnt smell. In the later stage of suction, there may be a risk of carbonization of the oil guide rope, which will affect the oil supply of the oil guide rope and affect the suction experience. In addition, the e-liquid has been infiltrating the oil guide rope, and the atomization amount of e-liquid cannot be controlled, which affects the smoking experience of consumers.
