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 an atomizing core and a liquid chamber configured for storing tobacco liquid. The atomizing core includes a liquid conducting element and a heating element. The atomizing core is usually replaceable. However, when replacing the atomizing core, tobacco liquid in the liquid chamber may leak out, thus rendering user experience unsatisfactory.
What are needed, therefore, are an atomizer and an electronic cigarette using same, which can overcome the above shortcomings.
An exemplary atomizer includes a main body of housing, a mouthpiece, an atomizing core, an atomizing cover. The main body of housing defines a liquid chamber configured for storing tobacco liquid. The mouthpiece is detachably connected with an end of the main body of housing. The atomizing core arranged in the main body of housing. The atomizing cover is arranged in the liquid chamber. The atomizing core is arranged in the atomizing cover. The atomizing cover has a top surface, and the top surface defines at least one liquid inlet. The atomizing core includes a heating element and a liquid conducting element surrounding the heating element. The liquid conducting element is configured for absorbing tobacco liquid flowed from the at least one liquid inlet, and the heating element is configured for atomizing the tobacco liquid in the liquid conducting element.
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.

Quite usefully, the liquid conducting element 1031 is an annular hollow structure, and the heating element 1032 is in contact with an internal wall of the liquid conducting element 1031. The liquid conducting element 1031 and the heating element 1032 are oriented along an axial direction of the atomizer 10. An internal space of the liquid conducting element 1031 is in communication with the air pipe 107. A top part of the liquid conducting element 1031 is adjacent to the liquid inlet 1052, the tobacco liquid permeates from the top part to a bottom part, and from an external wall to the internal wall. In the present embodiment, the liquid conducting element 1031 may be made of fiber cotton, or micro porous ceramic, and the heating element is a spiral heating wire.

The atomizing cover 105 defines an atomizing chamber, the atomizing core 103 is received in the atomizing chamber, and the liquid inlet is defined in a top surface 1051 of the atomizing cover 105. In the present embodiment, the atomizing cover 105 defines two symmetric liquid inlets 1052. The atomizing cover 105 further includes a tubular connecting end 1053 extending axially from the top surface 1051 of the atomizing cover 105. The tubular connecting end 1053 is hermetically coupled with a bottom end of the air pipe 107. A bottom end of the atomizing cover 105 is hermetically coupled to the main body of housing 101 via a sealing ring, preventing tobacco liquid in the liquid chamber 104 from leaking into the atomizing chamber via other positions except the liquid inlet 1052.

Quite usefully, the air pipe 107 is movable along an axial direction, a top end of the air pipe 107 is connected to the mouthpiece 102, and a bottom end of the air pipe 107 is connected to a sealing part 109. The sealing part 109 is configured for sealing the liquid inlet 108. A bottom part of the sealing part 109 abuts against an elastic element. In the present embodiment, the elastic element 106 is a spring. The sealing part 109 includes a flange, a sealing gasket is provided on the flange. When the sealing part 109 is moved upwards, the flange and the sealing gasket seal the liquid hole 108, and the spring abuts against a bottom surface of the flange. Referring to

Quite usefully, a sealing piece 112 is further provided on the positioning part 110. The sealing piece 112 is configured for sealing the liquid injecting hole 111, and is deformable. The sealing piece 112 is made of silicone, and is circular. The sealing piece 112 nests the air pipe 107. During liquid injecting process, an injector can push the sealing piece 112 open and insert into the first liquid chamber 1041. After finishing injecting, the sealing piece 112 restores to its original shape and seals the liquid injecting hole 111. Accordingly, liquid leakage is prevented when the atomizer 10 is turned over during liquid injecting process.
