Patent Application

The present invention relates to electronic cigarettes, and particularly to an atomizer and an electronic cigarette using same.
A typical electronic cigarette includes an atomizer and a power supply. The atomizer includes a mouthpiece, a liquid conducting component for absorbing tobacco liquid, and a heating wire for heating the tobacco liquid to vaporize. The liquid conducting component and the heating wire may be arranged at a front end, a middle part, or a rear end of the atomizer.
However, there are shortcomings if the liquid conducting component and the heating wire are simply arranged in these positions. When the liquid conducting component and the heating wire are arranged in the middle part, it is inconvenient to replace the liquid conducting component and the heating wire. When the liquid conducting component and the heating wire are arranged at the rear end, the tobacco liquid may leak from the rear end. When the liquid conducting component and the heating wire are arranged at the front end, the user of the atomizer may suck tobacco liquid in the liquid conducting component from the mouthpiece.
What are needed, therefore, are an atomizer and an electronic cigarette using same, which can overcome the above shortcomings.
An exemplary atomizer includes a housing and a mouthpiece assembly. The housing defines a liquid chamber for storing tobacco liquid. The mouthpiece assembly is arranged at a first end of the housing. The mouthpiece assembly defines an air passage and a backflow chamber. The backflow chamber includes a closed bottom end away from the housing, and an open near end adjacent to the housing. The open end is in communication with the air passage.
Many aspects of the present disclosure 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 disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Several definitions that apply throughout this disclosure will now be presented.
The term “outside” refers to a region that is beyond the outermost confines of a physical object. The term “inside” indicates that at least a portion of a region is partially contained within a boundary formed by the object. The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
Referring to
In the present embodiment, the housing 10 is transparent. An air pipe 12 is provided in the housing 10. The housing 10 and the air pipe 12 cooperatively define an annular liquid chamber 14. An end of the housing 10 away from the mouthpiece assembly 20 is provided with a screw sleeve 15. An insulated ring 16 and a tubular electrode 17 are arranged in the screw sleeve 15. The tubular electrode 17 is kept insulated from the screw sleeve 15 by the insulated ring 16. The screw sleeve 15 is coupled with the housing 10 by interference fit, so that liquid leakage is eliminated. The screw sleeve 15 defines an air inlet 152.
The housing 10 is provided with a hollow bracket 11 in an end adjacent to the mouthpiece assembly 20. A hollow silica holder 13 is arranged on the air pipe 12. The porous liquid conducting component 40 is hollow, nests the silica holder 13 and extends through the bracket 11. The air pipe 12 is in communication with the silica holder 13 and the porous liquid conducting component 40, so that air can reach a surface of the porous liquid conducting component 40, as seen in
The mouthpiece assembly 20 includes a front end 22 and a rear end 24. In the present embodiment, the front end 22 is threadedly coupled with the rear end 24. The front end 22 defines a central through hole 221. The rear end 24 defines an air passage 241 and a backflow chamber 242. The backflow chamber 242 includes a bottom end away from the housing 10, and a near end adjacent to the housing 10. The bottom end is closed; the near end is open, and is in communication with the air passage 241. Referring to
Part of the liquid conducting component 40 and part of the heating wire 50 are inserted into the backflow chamber 242. The bottom end 42 of the liquid conducting component 40 absorbs the tobacco liquid from the liquid chamber 14, and then the heating wire 50 heats the tobacco liquid in the liquid conducting component 40 to form aerosol. As seen in
Referring to
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.
