Abstract

An electronic cigarette comprising an atomizer and a first case configured for accommodating the atomizer is provided; the atomizer includes a heating mechanism, a breather pipe, and oil storage cotton, the heating mechanism is received inside the breather pipe, and the oil storage cotton envelops an outer surface of the breather pipe; wherein, the heating mechanism is positioned along an axial direction of the breather pipe, and has a shape matching an inner surface of the breather pipe. The heating mechanism in the electronic cigarette has a large effective heating area so that more smoke can be generated by the atomizer.

Claims

1. An electronic cigarette comprising an atomizer and a first case configured for accommodating the atomizer;

the atomizer including a heating mechanism, a breather pipe, and oil storage cotton, the heating mechanism received inside the breather pipe, and the oil storage cotton enveloping an outer surface of the breather pipe;

wherein, the heating mechanism is positioned along an axial direction of the breather pipe, and has a shape matching an inner surface of the breather pipe.

2. The electronic cigarette according to claim 1, wherein, the heating mechanism comprises a heating sleeve;

a shape of the heating sleeve matches a shape of the inner surface of the breather pipe;

an outer surface of the heating sleeve fits the inner surface of the breather pipe; and

a wall of the heating sleeve defines a plurality of first through-holes configured for enabling smoke oil to enter the heating sleeve.

3. The electronic cigarette according to claim 2, wherein, the plurality of first through-holes are strewn all around the wall of the heating sleeve and arranged in an array.

4. The electronic cigarette according to claim 1, wherein, the heating mechanism comprises a heating slice;

the heating slice has a shape matching the inner surface of the breather pipe, and fits the inner surface of the breather pipe; and

the heating slice defines a plurality of second through-holes configured for enabling smoke oil to enter the heating slice.

5. The electronic cigarette according to claim 4, wherein, the plurality of second through-holes are defined on the heating slice and arranged in an array.

6. The electronic cigarette according to claim 1, wherein, the heating mechanism comprises a heating coil having a rolling shape;

the heating coil is mounted on the inner surface of the breather pipe; and

the heating coil and the breather pipe are coaxial with each other.

7. The electronic cigarette according to claim 1, wherein, the breather pipe is formed by weaving glass fibers, and gaps formed between the glass fibers form passages for guiding smoke oil.

8. The electronic cigarette according to claim 7, wherein, the electronic cigarette further comprises a second case and a battery accommodated in the second case;

and the second case is connected with the first case detachably.

9. The electronic cigarette according to claim 8, wherein, a first conductive sleeve and a first electrode column are formed on an end of the first case that is adjacent to the second case;

both the first conductive sleeve and the first electrode column are connected with the heating mechanism;

the first conductive sleeve is mounted on the second case detachably, and the first electrode column is mounted inside the first conductive sleeve and insulated with the first conductive sleeve;

a second conductive sleeve and a second electrode column are formed on an end of the second case that is adjacent to the first case;

both the second conductive sleeve and the second electrode column are electrically connected with the battery respectively;
