Electronic cigarette

1. An electronic cigarette, comprising an outer sleeve, an atomizing assembly and a battery assembly both mounted inside the outer sleeve, and a bracket disposed between the atomizing assembly and the battery assembly; at least one first through-hole defined on a side wall of the outer sleeve, wherein the bracket includes a bracket body; a cylindrical first clearance is formed between an outer peripheral surface of the bracket body and an inner surface of the outer sleeve; a channel configured for air flow is formed from the first through-hole through the first clearance to the atomizing assembly;

wherein the bracket further includes a first butting part; the first butting part extends from an outer peripheral surface of the bracket body abutting the battery assembly to an inner surface of the outer sleeve; the first butting part and the inner surface of the outer sleeve abut against each other; and

wherein a second clearance is formed between the battery assembly and an inner surface of the outer sleeve; the first butting part is a ring structure; the bracket further includes a first venting recess defined on the first butting part and communicated with the second clearance; an opening of the first venting recess is towards an inner surface of the outer sleeve.

2. The electronic cigarette according to claim 1 , wherein the atomizing assembly is defined a fourth through-hole configured for air flow; the bracket further includes a second through-hole defined on an outer peripheral surface of the bracket body and communicated with the fourth through-hole.

3. The electronic cigarette according to claim 2 , wherein the bracket body is a cylindrical structure; the bracket further includes a third through-hole defined along an axial direction of the bracket body; the third through-hole is respectively communicated with the second through-hole and the fourth through-hole.

4. The electronic cigarette according to claim 3 , wherein the third through-hole is coaxially disposed on the bracket body.

5. The electronic cigarette according to claim 3 , wherein the third through-hole is coaxially connected to the fourth through-hole.

6. The electronic cigarette according to claim 1 , wherein more than one first venting recesses are disposed; the first venting recesses are uniformly arranged on the first butting part.

7. The electronic cigarette according to claim 1 , wherein the bracket further includes a second butting part; the second butting part extends from an outer peripheral surface of the bracket body abutting the atomizing assembly to an inner surface of the outer sleeve; the second butting part and the inner surface of the outer sleeve abut against each other.

8. The electronic cigarette according to claim 7 , wherein a second clearance is formed between the battery assembly and an inner surface of the outer sleeve; the second butting part is a ring structure; the bracket further includes a second venting recess defined on the second butting part and communicated with the second clearance; an opening of the second venting recess is towards an inner surface of the outer sleeve.

9. The electronic cigarette according to claim 8 , wherein more than one second venting recesses are disposed; the second venting recesses are uniformly arranged on the second butting part.

10. The electronic cigarette according to claim 1 , wherein the bracket body is defined a wire hole configured for a conductive wire through it; one end of the conductive wire is electrically connected to the atomizing assembly, and the other end of the conductive wire is electrically connected to the battery assembly.
