Abstract

An electronic cigarette, and a battery rod and an atomizer thereof are provided in the present application. The battery rod includes a battery rod body, and an air passage of the battery rod body is provided with a waterproof breathable component which cooperates with the air passage and is configured to prevent water from entering into the battery rod body via the air passage, and the atomizer includes an atomizer body, a smoke passage of the atomizer body is provided with a waterproof breathable component which cooperates with the smoke passage and is configured to prevent water from entering into the atomizer body via the smoke passage. Besides of ensuring the breathability of both the air passage and the smoke passage, the waterproof breathable component may also prevent external liquid from entering into the battery rod and the atomizer, thus the waterproof performance of the electronic cigarette is improved.

First claim

What is claimed is:

1. An electronic cigarette, comprising a battery rod and an atomizer which are connected to each other, wherein the battery rod comprises a battery rod body, an air passage is provided inside the battery rod body in an axial direction of the battery rod body and is configured to allow airflow to flow and to convey the airflow into the atomizer, and the air passage is provided with a first waterproof breathable component which cooperates with the air passage and is configured to prevent water from entering into the battery rod body via the air passage; and the atomizer comprises an atomizer body, a smoke passage configured to allow smoke to flow is provided inside the atomizer body in an axial direction of the atomizer body, and the smoke passage is provided with a second waterproof breathable component which cooperates with the smoke passage and is configured to prevent water from entering into the atomizer body via the smoke passage.

2. The electronic cigarette according to claim 1 , wherein the battery rod and the atomizer are of a non-detachable integrated structure.

3. The electronic cigarette according to claim 1 , wherein the battery rod body comprises a sleeve, and an end cover and a connecting member arranged at two ends of the sleeve, the connecting member is configured to connect the atomizer, an air inlet of the air passage is arranged at one end, away from the connecting member, of the battery rod body, and the first waterproof breathable component of the battery rod is arranged at an inner side of the end cover.

4. The electronic cigarette according to claim 1 , wherein the first waterproof breathable component and the second waterproof breathable component are each a waterproof breathable membrane.

5. The electronic cigarette according to claim 4 , wherein the waterproof breathable membrane is a polyethylene waterproof breathable membrane or a polytetrafluoroethylene waterproof breathable membrane.

6. The electronic cigarette according to claim 1 , wherein the first waterproof breathable component of the battery rod is arranged at an inner side or an outer side of an air inlet of the air passage.

7. The electronic cigarette according to claim 1 , wherein the atomizer body is provided with a mouthpiece end, and a connecting end configured to connect the battery rod, and the second waterproof breathable component of the atomizer is arranged at the mouthpiece end of the atomizer.
