Electronic Cigarette

The present invention provides an electronic cigarette including a soft pipe-stem composed of a stem portion and a mouthpiece. The stem portion is provided with a film onto its external wall. Using the pipe-stem made from soft material and attaching the film onto the external wall of the stem portion of the pipe-stem, the electronic cigarette can lead to soft and real experience of holding the cigar in hand and sucking by mouth, is more mimic and healthier.

DETAILED DESCRIPTION OF THE INVENTION

It is noted that, in case no interference is resulted in, the embodiments and features contained therein may be combined with each other. The present invention is described in greater detail in conjunction with the accompanying drawings and embodiments.

Reference is made toFIGS. 1-3. The present invention provides an electronic cigarette which includes a soft hollow pipe-stem10composed of a stem portion11and a mouthpiece12. The stem portion11is provided with a film100onto its external wall. The pipe-stem10is made from any one or more of the following soft material: silica gel, rubber, foam or EVA. The film100is a paper film or plastic film, and the paper film may be any one or more of the following papers: bond paper, thermal-sensitive paper or coated paper. The plastic film may be any one or more of the following films: PET film, PP film and PVC film.

As a first embodiment and as described above, the film100is attached only onto the external wall of the stem portion11, and the rest exposed portion of the pipe-stem10forms the mouthpiece12. As a second embodiment, the mouthpiece12is sleeved with a mouthpiece case120made of soft material. Specifically, the mouthpiece case120is of a hollow cylinder shape. Alternatively, the mouthpiece case120is 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 mouthpiece12attached with a paper film, the electronic cigarette of the invention is prevented from being soaked by user saliva.

A nozzle case20is mounted on a corresponding end of the mouthpiece12of the electronic cigarette. The nozzle cas220has an insertion end matched with the pipe-stem10. A suction hole is defined in the nozzle case20. In a second embodiment, the intake through hole is coaxial with the suction hole. Here, the nozzle case20is made from any one or more of the following material: silica gel, rubber, foam or EVA.

A light permeable cigar cap30is installed on a corresponding end of the stem portion11of the electronic cigarette. The cigar cap30is of a crown shape protruded outwardly and a light source is disposed at an inner side of the cigar cap30.

The electronic cigarette also includes a cigar liquid cup40, an atomization component50and a battery60.

In particular, the cigar liquid cup40is located inside the pipe-stem10and includes a cup body41and an atomization cartridge42. The cup body41is coaxial with the pipe-stem10and is tightly pressed against an inner wall of the pipe-stem10. The atomizer cartridge42is sealed and secured to one end of the cup body41. The cup body41includes oil retention cotton410, oil-guiding cotton411, a first glass fiber tube412and a second glass fiber tube413all of which are hollow. The oil retention cotton410is pressed against the inner wall of the pipe-stem10and is coaxial with the pipe-stem10. The oil-guiding cotton411is pressed against an inner wall of the oil retention cotton410and placed coaxially with the pipe-stem10in a contact region of the atomization component50. A groove is defined circumferentially at a middle portion of the oil-guiding cotton411. The first glass fiber tube412is a helix formed by enwinding helically a glass fiber wire and is accommodated inside the groove. The second glass fiber tube413is pressed against the inner walls of the first glass fiber tube412and oil-guiding cotton411respectively and is disposed coaxially with the pipe-stem10. Cigar oil will be accumulated more quickly and holding of the atomization component50will be enhanced by means of the above construction.

The atomization component50is held along radial direction of the cup body41inside the cup body41. The atomization component50includes an oil-guiding member51which passes across a corresponding hole of the second glass fiber tube13and is pressed against the inner wall of the cup body412and an electric heater coil52enwound on the oil-guiding member51. Here, the oil-guiding member51is also constructed of glass fiber with good oil absorption effects.

The battery60is placed on one end of the pipe-stem10corresponding to the stem portion11. Two electrodes of the battery60are coupled with two ends of the electric heater coil52respectively through a conductive wire which passes through the atomization cartridge42and cup body41.

The electronic cigarette also includes a holding bracket70and a gas sensor80. Specifically, the holding bracket70is provided at one end of the pipe-stem10corresponding to the stem portion11. The gas sensor80is secured on the holding bracket70and electrically connected to the battery60. The above structure is stable and reliable.
