Description

TECHNICAL FIELD

The present invention relates to an electronic cigarette.

DESCRIPTION OF RELATED ART

Referring to FIG. 6 a typical electronic cigarette includes a battery assembly 1 and an atomizing device 2 arranged on the battery assembly 1. The atomizing device 2 has tobacco solution and a heating assembly 6 for heating the tobacco solution. Currently, in order to make good electrical connection between the battery assembly 1 and the atomizing device 2, a long distance of threads is used at a connection end of each of the battery assembly 1 and the atomizing device 2, resulting that dismounting the atomizing device 2 and the battery assembly 1 from each other is inconvenient.

What is needed, therefore, is an electronic cigarette which can overcome the above shortcomings.

DETAILED DESCRIPTION

Embodiments of the present electronic cigarette will now be described in detail below and with references to the drawings.

Referring to FIGS. 1 to 3, an electronic cigarette in accordance with a first embodiment is provided. The electronic cigarette includes a battery assembly 1 and an atomizing device 2.

The atomizing device 2 has a tobacco solution containing space 4, and a heating assembly 6 configured for heating the tobacco solution. The atomizing device 2 further has a connecting portion 7 protruded from an end thereof The connecting portion 7 is ring-shaped, and has an electrode ring 5 positioned therein. In the present embodiment, an outer wall of the connecting portion 7 is flat and smooth, and the connecting portion 7 is made of a ferromagnetic material, such as iron, cobalt, nickel which can be magnetized and can be electrically conductive.

The battery assembly 1 includes a receiving space 3 defined at an end thereof, an electrode ring 9 positioned in the receiving space 3, a magnetic block 10 and an insulated ring 12. The magnetic block 10 is positioned in the receiving space 3 around the electrode ring 9, and the insulated ring 12 is located between the electrode ring 9 and the magnetic block 10. The magnetic block 10 can be a permanent magnet.

In assembly, when the connecting portion 7 of the atomizing device 2 is inserted in the receiving space 3 of the battery assembly 1, due to magnetic attraction between the connecting portion 7 and the magnetic block 10, the atomizing device 2 and the battery assembly 1 can be connected quickly, therefore the electrode ring 5 can contact the electrode ring 9 for electrical connection, and the heating assembly 6 can work for heating the tobacco solution in the atomizing device 2.

In the present embodiments, the receiving space 3 is provided by a ring-shaped magnetizable member 8, such as an iron member or magnetic ceramic, thereby a magnetic force of the battery assembly 1 can be enhanced. An inner wall of the receiving space 3 is flat and smooth. The magnetizable member 8 can be electrically conductive, or insulated. When the magnetizable member 8 is electrically conductive, the connecting portion 7 of the atomizing device 2 can be electrically connected to the magnetizable member 8. When the magnetizable member 8 is insulated, the connecting portion 7 of the atomizing device 2 can be electrically connected to a metallic battery sleeve of the battery assembly 1.

In other embodiments, the receiving space 3 can be directly provided by a battery sleeve of the battery assembly 1.

In addition, in the present embodiment, an elastic member 11 is applied to the electrode ring 9 of the battery assembly 1, that is, the electrode ring 9 is fixed by the elastic member 11 in the insulated ring 12. The elastic member 11 can be selected from a group consisting of spring, resilient sheet and silicon rubber ring. Due to the elasticity of the elastic member 11, the electrode ring 9 can stretch out and draw back, such that a contact between the electrode ring 5 and the electrode ring 9 can be tightly, and therefore a good electrical connection between the electrode ring 5 and the electrode ring 9 can be attained. In addition, due to stretchable elastic member 11, a connection depth between the battery assembly 1 and the atomizing device 2 can be adjusted.

Referring to FIG. 4, an electronic cigarette in accordance with a second embodiment is provided. The electronic cigarette of the second embodiment is essentially similar to the electronic cigarette of the first embodiment, only differs that an atomizing device 2 of the electronic cigarette of the second embodiment also has a magnetic block 10, and the magnetic block 10 is arranged near a connecting portion 7 of the atomizing device 2.

Referring to FIG. 5, an electronic cigarette in accordance with a third embodiment is provided. In the present embodiment, a battery assembly 1 has a connecting portion 71 protruded from an end thereof, and an atomizing device 2 has a magnetizable member 81 having a receiving space 31. The connecting portion 71 is preferably made of a permanent magnet. In assembly, the battery assembly 1 is inserted into the receiving space 31 of the atomizing device 2, and the connecting portion 71 is quickly magnetically attracted by the magnetizable member 81. A magnetic block 10 can be avoided in present embodiment.

By the above magnetic connection, threaded connection can be avoided. However, in some situations, upon the magnetic connection, a short distance of threads is not excluded to each of the battery assembly 1 and the atomizing device 2 to enhance the connection.

It is understood that the above-described embodiments are intended to illustrate rather than limit the disclosure. Variations may be made to the embodiments and methods without departing from the spirit of the disclosure. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the disclosure.
