Abstract

An elastic electrode structure for an electronic cigarette is disclosed. The electronic cigarette includes an atomizing assembly and a battery assembly. The battery assembly has a threaded sleeve arranged on an upper end thereof. The elastic electrode structure includes an electrode ring arranged in the threaded sleeve. The electrode ring has a lower end extending out from a through hole defined at the bottom of the threaded sleeve. The elastic electrode structure further includes an insulating ring arranged between the electrode ring and the threaded sleeve, and the elastic electrode structure further includes an elastic sealing ring arranged between the electrode ring and the insulating ring. The elastic electrode structure has good leak-proofing effect and low cost.

First claim

What is claimed is:

1. An elastic electrode structure for an electronic cigarette, the electronic cigarette comprising an atomizing assembly and a battery assembly, the battery assembly having a threaded sleeve arranged on an upper end thereof, and the elastic electrode structure further comprising an electrode ring arranged in the threaded sleeve, wherein the electrode ring has a lower end extending out from a through hole defined at the bottom of the threaded sleeve, the elastic electrode structure further comprises an insulating ring arranged between the electrode ring and the threaded sleeve, and the elastic electrode structure further comprises an elastic sealing ring arranged between the electrode ring and the insulating ring;
wherein the insulating ring has a flange on an upper end thereof, and the flange has an outer diameter greater than an inner diameter of the through hole;
wherein the electrode ring has an end part, and the end part has a diameter greater than an inner diameter of a hollow ring-shaped part of the insulating ring;
wherein the sealing ring has an upper end abutting against underside of the end part of the electrode ring, and the sealing ring has a lower end abutting against the flange on the upper end of the insulating ring.

2. The elastic electrode structure according to claim 1 , wherein a spring is arranged between a periphery of the electrode ring and an inner side of the insulating ring, and the spring is located in the hollow ring-shaped part.

3. The elastic electrode structure according to claim 1 , wherein the sealing ring is a hollow body, and the sealing ring has openings on both upper and lower ends thereof; and the electrode ring passes through both the openings on the upper and lower ends of the sealing ring.

4. The elastic electrode structure according to claim 3 , wherein the sealing ring has a diamond part on a middle part thereof; in a natural state, the diamond part and an inner wall of the threaded sleeve have a gap therebetween; and, in a working state, the diamond part abuts against the inner wall of the threaded sleeve.

5. The elastic electrode structure according to claim 1 , wherein insulating silica gel is arranged on the periphery of a lower end of the threaded sleeve.

6. The elastic electrode structure according to claim 1 , further comprising an electrode cap, wherein the electrode cap is connected to a bottom end of the sealing ring.

7. The elastic electrode structure according to claim 1 , wherein the sealing ring is made of silica gel.
