Description

Electronic cigarettes that can store large volumes of e-liquid

technical field

The utility model relates to the field of electronic cigarettes, in particular to an electronic cigarette capable of storing large-capacity smoke liquid. the

Background technique

As a substitute for traditional cigarettes, electronic cigarettes mainly use power supply to atomize the smoke liquid (nicotine-containing solution) stored inside to generate smoke for people to smoke, so as to simulate the smoking effect of traditional cigarettes. At present, traditional electronic cigarettes are generally divided into two types: integrated type and split type. The integrated type electronic cigarette mainly means that the battery and atomizer are located in the same housing, and at the same time, an area for containing the liquid is defined in the housing; while the split type The electronic cigarette is assembled from two parts: an atomization component and a power supply component. The battery is located in the power supply component, the atomizer is located in the atomization component, and the smoke liquid is also loaded in the atomization component. The common defect of these two types of electronic cigarettes is that when the volume of electronic cigarettes is fixed, the space for containing e-liquid inside them is very limited, which will eventually affect the number of smoking ports of electronic cigarettes.

Since the above-mentioned annular space is only located on a length of the entire plastic tube, the space is small, and the oil absorption capacity of the tobacco cotton is limited, so the storage capacity of the e-cigarette for this electronic cigarette is relatively small. Another example is the Chinese patent application CN201320520287.1 which discloses an atomization assembly, a battery assembly and an electronic cigarette, that is, the above-mentioned split electronic cigarette, wherein the atomization assembly includes an atomization sleeve and a ventilator in the middle, and the smoke liquid is contained in In the annular space between the atomizing sleeve and the ventilation pipe, due to the small length of the atomizing component itself, the length of the annular space inside is also very limited, so the e-cigarette has a small liquid storage capacity , it needs frequent refilling of e-liquid, which is inconvenient to use.
