DISPOSABLE ELECTRONIC CIGARETTE
This invention discloses a disposable electronic cigarette, comprising a cigarette holder and a cigarette rod, the cigarette holder defining an air outlet hole, wherein, at least three air inlet holes are defined in a cigarette rod wall of the cigarette rod, the air inlet holes and the air outlet hole cooperatively form an airflow loop, and at least one indicator light corresponding to the air inlet holes is mounted on the cigarette pipe to indicate positions of the air inlet holes and/or operation states of the electronic cigarette. When users holds the electronic cigarette, the indicator light will indicate the positions of the air inlet holes, and users can adjust the air inflow amount to keep a smooth airflow.
1 . A disposable electronic cigarette comprising a cigarette holder ( 1 ) and a cigarette rod, the cigarette holder ( 1 ) defining an air outlet hole, wherein, at least three air inlet holes ( 21 ) are defined in a cigarette rod wall ( 2 ) of the cigarette rod, the air inlet holes ( 21 ) and the air outlet hole cooperatively form an airflow loop, and at least one indicator light corresponding to the air inlet holes is mounted on the cigarette rod to indicate positions of the air inlet holes and/or operation states of the electronic cigarette.
2 . The disposable electronic cigarette of claim 1 , wherein, the indicator light is embedded in at least one of the air inlet holes ( 21 ), with a gap formed therebetween, and partially contacts an inner surface of the air inlet hole; or the indicator light is mounted at a position of the cigarette rod wall ( 2 ) that is adjacent to the air inlet holes ( 21 ); or the indicator light is embedded in a position of the cigarette rod wall ( 2 ) corresponding to positions of the air inlet holes( 21 ).
3 . The disposable electronic cigarette of claim 1 , wherein the air inlet holes ( 21 ) are arranged to form a warning pattern.
4 . The disposable electronic cigarette of claim 3 , wherein the warning pattern is snakelike or spiral.
5 . The disposable electronic cigarette of claim 1 , wherein the air inlet holes ( 21 ) are shaped as any one of circle, polygon, kidney, and ellipse.
6 . The disposable electronic cigarette of claim 2 , wherein the disposable electronic cigarette further comprises a battery ( 4 ) and an atomizer ( 3 ) including heating wires ( 31 ), which are both mounted in the cigarette rod; and the cigarette rod wall of the cigarette rod ( 2 ) sleeves the atomizer ( 3 ) and the battery ( 4 ), with a first gap ( 20 ) formed between the atomizer ( 3 ) and the battery ( 4 ) along an axial direction.
7 . The disposable electronic cigarette of claim 6 , wherein the at least three air inlet holes ( 21 ) communicate with the first gap ( 20 ).
8 . The disposable electronic cigarette of claim 7 , wherein the atomizer ( 3 ) comprises an atomizing passage ( 30 ) formed along an axial direction of the cigarette rod wall ( 2 ) and communicating with the first gap ( 20 ), and an end of the atomizer ( 3 ) that is away from the battery ( 4 ) communicates with the cigarette holder ( 1 ).
9 . The disposable electronic cigarette of claim 8 , wherein a breather pipe ( 10 ) that is coaxial with the atomizing passage ( 30 ) is mounted between the cigarette holder and the atomizer ( 3 ), and the breather pipe ( 10 ) communicates with the air inlet holes ( 21 ) and the atomizing passage ( 30 ) respectively.
10 . The disposable electronic cigarette of claim 3 , wherein the indicator light is electrically connected with the battery ( 2 ), and is supplied with power by the battery ( 2 ).
11 . The disposable electronic cigarette of claim 10 , wherein the at least three air inlet holes ( 21 ) are defined in a circumference of the cigarette rod wall ( 2 ) corresponding to the first gap ( 20 ).
12 . The disposable electronic cigarette of claim 11 , wherein the indicator light is mounted in the first gap ( 20 ).
13 . The disposable electronic cigarette of claim 12 , wherein a second gap ( 120 ) is formed between the rod wall ( 2 ) and the battery ( 4 ).
14 . The disposable electronic cigarette of claim 13 , wherein the at least three air inlet holes ( 21 ) are defined in positions of the cigarette rod wall ( 2 ) corresponding to the second gap ( 120 ).
15 . The disposable electronic cigarette of claim 1 , wherein the at least three air inlet holes ( 21 ) are equidistantly defined in positions of the cigarette rod wall ( 2 ) arranged in a same radial direction.
16 . The disposable electronic cigarette of claim 1 , wherein the at least three air inlet holes ( 21 ) are equidistantly defined in positions of the cigarette rod wall ( 2 ) arranged in a same axial direction.
17 . The disposable electronic cigarette of claim 1 , wherein at least one layer of sticker ( 22 ) is attached on an outer surface of the cigarette rod wall ( 2 ), and a second through hole corresponding to the air inlet holes ( 21 ) and third through hole corresponding to the indicator light are defined in the sticker ( 22 ).
