Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts are within the scope of the present invention.

The utility model provides an electronic cigarette with an atomizing core insulating ring as a stopping structure. For the specific overall structure, please refer to Figure 2. Please refer to the structure split diagram 3 and the electronic cigarette shown in Figure 4, including:

Electronic cigarette body 100;

The electronic cigarette body 100 is provided with an atomizing assembly 101 and a battery assembly 104 detachably connected to the atomizing assembly 101; the atomizing assembly 101 includes an atomizing core 102 for atomizing smoke oil and An atomizing sleeve 103 disposed on the atomizing core 102; the atomizing core 102 is provided with an electrode assembly for electrically connecting with the battery assembly 104, the electrode assembly includes an inner electrode 201, and is sleeved on An insulating ring 202 on the inner electrode and an outer electrode 203 sleeved on the insulating ring; a stopper portion 301 is disposed on an outer peripheral surface of the inner electrode 201; the insulating ring 202 is disposed with the inner portion The stop portion 301 of the electrode 201 is adapted to the stop groove 302. Therefore, it can be seen that the inner electrode and the insulating ring are relatively rotated by the matching of the stopping portion and the stopping groove, and the electrode on the battery rod drives the atomizing core when the battery rod and the atomizing sleeve are rotatably assembled together. The upper electrode rotates and the electronic wire is broken to ensure that the electronic cigarette works normally.

Referring to FIG. 5 and FIG. 6, the cross section of the stopping portion 301 is an arcuate shape in which two arcs are cut along two tangents, which is not limited thereto. The arcuate shape is rounded to remove two arcuate faces, the arcuate shape having an angular shape.
