Abstract

Disclosed is an electronic cigarette with an atomization core (12) in which a plurality of atomization assemblies are placed side by side. An atomization seat (32) of the atomization core (12) is provided with an accommodating groove (33) for accommodating a plurality of electrothermic assemblies (34). A space interval is reserved between every two electrothermic assemblies (34). Each of the electrothermic assemblies (34) can be mounted into the atomization seat (32) from the accommodating groove (33) having an opening at one end. An oil guide rope (52) has a good elasticity. The width of the accommodating groove (33) is less than the diameter of the oil guide rope (52), so that the accommodating groove (33) can clamp the oil guide rope (52). The electronic cigarette solves the problem that the amount of smoke is small because the smoke generated by electric heating wires (51) cannot be taken by a smoke flow in time due to the oil guide rope (52) placed between the electric heating wires (51), and has the advantage of convenient assembly. Since the cross-sectional area of the clamped oil guide rope (52) is reduced, the oil storage capacity of the oil guide rope (52) can be controlled, so that too much cigarette oil may not be inhaled, thereby ensuring that when a user smokes, the electric heating wires (51) can conduct sufficient atomization to generate a large amount of smoke. In this way, in the case of not adding a production process, the problem that the amount of smoke is too small because of insufficient atomization caused by too large an oil inflow is avoided.

The oil storage chamber 23 stores the oil, which shortens the length of the electronic cigarette and is convenient for the user to carry. The mouthpiece assembly 11 is detachably coupled to the sleeve 13 and holds the atomizing core 12 therebetween. When the smoke oil in the oil reservoir 23 of the mouthpiece assembly is used up, the connection sleeve 13 can be opened to add the smoke oil to the oil storage chamber 23, thereby increasing the use time of the electronic cigarette. Moreover, if the atomizing core 12 is damaged, the atomizing core 12 can be taken out for easy replacement.

Referring to FIG. 5, the atomizing core is provided with an atomizing sleeve 31, an atomizing base 32, and an atomizing assembly. The atomizing assembly includes at least two electric heating components for atomizing the tobacco oil.
