Technical Field

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

Background

The electronic cigarette is an electronic product simulating a cigarette, and has the same appearance, smoke, taste and sensation as the cigarette. The atomizer is powered by a rechargeable lithium polymer battery, and nicotine and the like are converted into steam through heating tobacco tar in an oil tank, so that a user can absorb the steam.

The cartridge is used to store tobacco tar. When the smoking set is used, the tobacco tar flows to the heating element through the oil guide element, and the tobacco tar is atomized to generate smoke through heating, so that a user can smoke the smoking set.

Detailed Description

It is to be understood that the terminology, the specific structural and functional details disclosed herein are for the purpose of describing particular embodiments only, and are representative, but that the present invention may be embodied in many alternate forms and should not be construed as limited to only the embodiments set forth herein.

The invention is described in detail below with reference to the figures and alternative embodiments.

As shown in fig. 1 to 5, as an embodiment of the present invention, there is disclosed a cartridge including a housing 100 and an atomizing core 200; a cavity 110 for containing tobacco tar is formed inside the shell 100; the shell 100 extends inwards to form an air passage structure 120, and the air passage structure 120 is hollow to form an air passage 121; the air passage structure 120 is provided with a liquid passing hole 122 for communicating the cavity 110 with the air passage 121; the atomizing core 200 is installed in the air passage 121 and seals the liquid passing hole 122; the inner wall surface of the air passage structure 120 is provided with a vent groove 123 corresponding to the position of the atomizing core 200.

Because the tobacco tar in the cartridge needs to flow to the heating element 210 for heating, and the heated and atomized smoke is discharged for the user to suck, the cartridge cannot be completely sealed for the smoke to flow out. However, the cartridge needs to have a certain degree of sealing to prevent the oil from leaking out of the cartridge before use. At present, because the cigarette bullet needs to have certain leakproofness, the tobacco tar is difficult to flow in time on heating member 210 when the electron cigarette is used, leads to heating member 210 dry combustion, and the electron cigarette is easy to damage, and the tobacco tar is also difficult to use up completely.

According to the cigarette cartridge, the ventilation groove 123 is formed in the position, corresponding to the atomizing core 200, of the inner wall surface of the air channel structure 120, air can enter the cavity 110 through the liquid hole 122 more easily, air pressure of the cavity 110 and the outside is balanced, it is guaranteed that tobacco tar can normally flow onto the atomizing core 200, the atomizing core 200 is not prone to dry burning, an electronic cigarette is not prone to damage, and the tobacco tar is easy to normally use up.

In the cartridge of the present invention, when the atomizing core 200 is installed in the air passage 121, the liquid passing hole 122 is blocked, so that the tobacco tar is not easy to flow out from the cavity 110. In use, the tobacco tar may then flow through the liquid passage holes 122 to the atomizing core 200 for heating. However, when the atomization core 200 is sealed too tightly, the external air is difficult to enter the cavity 110 through the liquid hole 122. The cavity 110 creates a negative pressure and the tobacco smoke is difficult to flow onto the atomizing core 200. The vent groove 123 is provided, and the vent groove 123 can be used for air inflow, so that air can enter the cavity 110 through the liquid hole 122 more easily, and the air pressure of the cavity 110 and the outside is balanced.
