Reference is made to
As a first embodiment and as described above, the film 100 is attached only onto the external wall of the stem portion 11, and the rest exposed portion of the pipe-stem 10 forms the mouthpiece 12. As a second embodiment, the mouthpiece 12 is sleeved with a mouthpiece case 120 made of soft material. Specifically, the mouthpiece case 120 is of a hollow cylinder shape. Alternatively, the mouthpiece case 120 is of a barrel shape, one end of which is opened while the other end is provided with an intake through hole in its bottom wall. Compared with a prior art electronic cigarette of which the external wall of the pipe-stem made from hard material is attached with paper or plastic film, the electronic cigarette of the invention can lead to soft experience of holding a conventional cigar in hand and sucking by mouth, is more mimic, healthier, produces more real user experience, and complies with food standard without causing risk to user health. In addition, compared to a conventional mouthpiece 12 attached with a paper film, the electronic cigarette of the invention is prevented from being soaked by user saliva.
A nozzle case 20 is mounted on a corresponding end of the mouthpiece 12 of the electronic cigarette. The nozzle cas2 20 has an insertion end matched with the pipe-stem 10. A suction hole is defined in the nozzle case 20. In a second embodiment, the intake through hole is coaxial with the suction hole. Here, the nozzle case 20 is made from any one or more of the following material: silica gel, rubber, foam or EVA.
A light permeable cigar cap 30 is installed on a corresponding end of the stem portion 11 of the electronic cigarette. The cigar cap 30 is of a crown shape protruded outwardly and a light source is disposed at an inner side of the cigar cap 30.
The electronic cigarette also includes a cigar liquid cup 40, an atomization component 50 and a battery 60.
In particular, the cigar liquid cup 40 is located inside the pipe-stem 10 and includes a cup body 41 and an atomization cartridge 42. The cup body 41 is coaxial with the pipe-stem 10 and is tightly pressed against an inner wall of the pipe-stem 10. The atomizer cartridge 42 is sealed and secured to one end of the cup body 41. The cup body 41 includes oil retention cotton 410, oil-guiding cotton 411, a first glass fiber tube 412 and a second glass fiber tube 413 all of which are hollow.
