Abstract
Description
- The present disclosure relates to electronic cigarettes, particularly to an atomizing device having a ventilation member and an electronic cigarette having the atomizing device.
- An electronic cigarette generally includes an atomizing device and a power source electrically connected to the atomizing device. The atomizing device includes a heating assembly atomizing a tobacco solution. Referring to
FIG. 10 , a typical atomizing device includes a liquid reservingmember 14 wrapping around an air pipe 1' and configured for reserving a tobacco solution. During work, the heating assembly atomizes the tobacco solution absorbed from the liquid reservingmember 14, then the atomized tobacco solution flows towards a user through the air pipe 1', thereby achieving a smoking effect. However, the liquid reservingmember 14 will cause a chemical reaction and finally influence a taste of the tobacco solution after the liquid reservingmember 14 is immersed into the tobacco solution for a long time. - Therefore, what is needed is a new kind of atomizing device without a liquid reserving member and electronic cigarette having the atomizing device.
- Many aspects of the present atomizing device, ventilation member and electronic cigarette can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the present atomizing device, ventilation member and electronic cigarette. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.

- Referring to
FIGs. 1 and 3 , a ventilation member provided for an electronic cigarette in accordance with a first embodiment is provided. The ventilation member includes anair pipe 1 and aflange 3 formed on theair pipe 1. Acavity 32 is formed inside theflange 3 and in communication with anairflow channel 2 formed inside theair pipe 1. Thecavity 32 is configured to reserve and purify an atomized tobacco solution which flows from theair pipe 1. Furthermore, the ventilation member is T-shaped, and an inclined surface 4 is formed between theflange 3 and theair pipe 1 for guiding the tobacco solution flowing towards theair pipe 1, thereby preventing the user from sucking the tobacco solution during smoking. In other embodiments, the inclined surface can be a curved surface or a streamline surface. - In the present embodiment, the
flange 3 and theair pipe 1 are integrally formed. In other embodiments, theflange 3 and theair pipe 1 can be preformed separately, and then connected together by cementation. - In the present embodiment, the
flange 3 and theair pipe 1 are made of plastic materials. In other embodiments, they can be made of metallic materials or other materials. In addition, theflange 3 and theair pipe 1 are manufactured by injection molding. - Referring to
FIG. 2 , a ventilation member provided for an electronic cigarette in accordance with a second embodiment is provided. The difference between the ventilation member of the present embodiment and that of the first embodiment is that a guidingwall 31 is further provided to extend downwards from theflange 3 along a direction parallel to theair pipe 1. The guidingwall 31 increases a contacting area of the ventilation member and the atomizingsleeve 8, thus the ventilation member and the atomizingsleeve 8 can be assembled more conveniently. - Referring to
FIG. 4 , in the present embodiment, a reinforcing rib 7 is formed on an outer wall of theair pipe 1 and a length of the reinforcing rib 7 is shorter than that of theair pipe 1. - Referring to
FIG. 5 , in the present embodiment, asealing ring 5 is arranged on an external surface of theflange 3. - Referring to
FIG. 6 , an atomizingdevice 100 provided for an electronic cigarette in accordance with a third embodiment is provided. The atomizing device includes an atomizingsleeve 8, a mouthpiece 9, asupport 11, aheating assembly 12, and a ventilation member (not shown) fixed in the atomizingsleeve 8. The ventilation member is same to the one of the first embodiment. Anannular space 13 is formed between theair pipe 1 and the atomizingsleeve 8, and configured for containing a tobacco solution. Theannular space 13 does not have a liquid reserving member received therein. Thesupport 11 is ring-shaped, and has aninner space 16 defined therein. Theair pipe 1 is fixed on thesupport 11, and asealing cover 10 is arranged on thesupport 11. Theheating assembly 12 is positioned under thesupport 11. Aslot 15 is formed between an outer wall of thesupport 11 and an inner wall of thesleeve 8 to allow the tobacco solution to flow towards theheating assembly 12. Theinner space 16 of thesupport 11 forms an atomizing chamber for theheating assembly 12 and is in communication with theair pipe 1. - Based on the above described assembly of the
annular space 13, thesupport 11 and theheating assembly 12, when the user smokes at the mouthpiece 9, , a negative pressure will be generated in theannular space 13 with the reduction of the tobacco solution in theannular space 13 caused by the smoke of the user. In thus situation, due to the negative pressure, the tobacco solution in theannular space 13 would not leak out when the atomizing device stands upwards. - Referring to
FIG. 6 again, in the present embodiment, the ventilation member is fixed in the atomizingsleeve 8 based on interference fit between theflange 3 and the atomizingsleeve 8. Specifically, a guidingwall 31 extends downwards from theflange 3 along a direction parallel to theair pipe 1, and asealing ring 5 is arranged at an external surface of theflange 3. Theflange 3 and theair pipe 1 are both made of plastic materials. As plastic materials will be expanded after injection molding, it will be hard to ensure an interference fit between theflange 3 and the atomizingsleeve 8, therefore, thesealing ring 5 can ensure that the tobacco solution will not be leaked out. - Referring to
FIGs. 7 and 8 , an atomizingdevice 200 for an electronic cigarette in accordance with a fourth embodiment is provided. In addition to the atomizing device of the third embodiment, the atomizing device of the fourth embodiment further includes a reinforcing rib 7 arranged at an outer wall of anair pipe 1. A length of the reinforcing rib 7 is defined shorter than that of theair pipe 1 in helpful of assembling theair pipe 1 to the atomizingsleeve 8,. Specifically, referring toFIG. 8 , the bottom of theair pipe 1 is inserted into asealing cover 10, and the reinforcing rib 7 is fixed on the top of thesealing cover 10. - Referring to
FIG. 9 , anelectronic cigarette 300 in accordance with a fifth embodiment is provided. Theelectronic cigarette 300 includes an atomizing device 100(200) and abattery assembly 400 electrically connected to the atomizing device 100(200) - It is understood that the above-described embodiments are intended to illustrate rather than limit the disclosure. Variations may be made to the embodiments and methods without departing from the spirit of the disclosure. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the disclosure.
