Abstract

An electronic cigarette comprising a battery pole, an atomizer, and a connecting mechanism disposed between the battery pole and the atomizer and configured for connecting the battery pole to the atomizer is provided; the connecting mechanism includes a first connecting member and a second connecting member; and the first connecting member includes a first buckled portion and a first connecting portion detachably connected with the first buckled portion; the second connecting member includes an accommodating portion fitting for the first buckled portion; and the first buckled portion is fixed in the accommodating portion, so that the first buckled portion is detachably buckled with the second connecting member. The electronic cigarette of the present application is easy to assemble and disassemble, and convenient to produce.

Claims

1. An electronic cigarette comprising a battery pole, an atomizer, and a connecting mechanism disposed between the battery pole and the atomizer and configured for connecting the battery pole to the atomizer;

the connecting mechanism including a first connecting member and a second connecting member, wherein the first connecting member includes a first buckled portion and a first connecting portion detachably connected with the first buckled portion;

the second connecting member includes a second connecting portion and an accommodating portion detachably connected with the second connecting portion;

the accommodating portion fits for the first buckled portion;

the first buckled portion is fixed in the accommodating portion, so that the first buckled portion is detachably buckled with the second connecting member;

wherein a side edge of the accommodating portion defines a guiding recess configured for cooperatively enabling the first buckled portion to be inserted in the accommodating portion; and

an inner surface of the accommodating portion defines a locating recess disposed peripherally and communicating with the guiding recess;

wherein the first buckled portion includes a first section and a second section integrated with the first section;

a protruding portion is arranged on edge of outside surface of the second section;

when the first buckled portion is inserted in the accommodating portion, the protruding portion moves along the guiding recess and then enters rotationally the locating recess of the accommodating portion;

wherein the first buckled portion and the protruding portion are integrally made of plastic material by plastic injection;

an axial direction of the protruding portion coincides with a radial direction of the second section;

wherein the accommodating portion is made of plastic material by plastic injection;

wherein the locating recess runs through a side wall of the accommodating portion;

and the protruding portion can be squeezed into the guiding recess by certain elasticity of the protruding portion, and then enters the locating recess;

wherein the first connecting portion is cylindrical; and

the first buckled portion is cylindrical; and

the first section is inserted in the first connecting portion;

wherein the electronic cigarette further comprises a first electrode pillar and a second electrode pillar, the first electrode pillar is passed through and located inside the accommodating portion of the second connecting member;

the second electrode pillar is passed through and located inside the first buckled portion of the first connecting member; and

wherein the first connecting portion and the second connecting portion are made of metal;

when the first connecting member is buckled with the second connecting member, the first connecting portion is electrically connected to the second connecting portion, the first electrode pillar is abutted against with and electrically connected to the second electrode pillar, and the first electrode pillar is electrically insulated with the second connecting portion via the accommodating portion, the second electrode pillar is electrically insulated with the first connecting portion via the first buckled portion.

2. The electronic cigarette according to claim 1, wherein a first through-hole configured for air flow is defined in the first electrode pillar;

and a second through-hole configured for air flow is defined in the second electrode pillar; and

the first through-hole communicates with the second through-hole.

3. The electronic cigarette according to claim 2, wherein the atomizer includes a heating filament;

and two ends of the heating filament are electrically connected to the first connecting portion and the second electrode pillar respectively; and
