Patent Application
20170325510
The present invention relates to electronic cigarettes, and particularly to a heating device for an electronic cigarette, and an atomizer using same.
In a typical electronic cigarette, a heating device includes a solid heating wire. However, a surface area of the heating wire is small, and accordingly, a contact surface between the heating wire and a liquid conducting body is small. Therefore, an atomizing efficiency of the electronic cigarette is low.
What are needed, therefore, are a heating device and an atomizer having same, which can overcome the above shortcomings.
The present disclosure relates to a heating device for an electronic cigarette. The heating device includes a heating part, a first conductive part, and a second electrically conductive part. The heating part has a hollow metallic tube wound in a spiral form. The first conductive part is electrically connected to a first end of the metallic tube. The second electrically conductive part is electrically connected to an opposite second end of the metallic tube.
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 temperature sensor includes two thermocouple wires 205, 206. The two thermocouple wires 205 are connected with each other in one end, and arranged side by side in the heating part 201. The thermocouple wires 205, 206 are insulated from each by the insulating medium 207. The temperature sensor can detects a temperature of the heating part 201, and sends a temperature signal to a controller of the electronic cigarette. The controller can keep a constant heating temperature of the heating device 200 based on the temperature signal.
An end of one of the thermocouple wires 205, 206 is connected to the first or the second conductive parts 202, 203, while an end of the other of the thermocouple wires 205, 206 is connected with a signal end 204. The signal end 204 passes through the metallic tube and through a hollow space of the heating part 201. Referring to

Quite usefully, the atomizing unit 400 further includes a liquid conducting body 402 in contact with the heating part 201. The liquid conducting body 402 is configured for absorbing tobacco liquid from the liquid chamber 303, and providing the heating part 201 with the tobacco liquid. In the present embodiment, the liquid conducting body 402 is made of porous ceramic or cellucotton. The liquid conducting body 402 is arranged in an internal chamber of a main body 401. The main body 402 defines an air inlet 404 at a first end, and an aerosol outlet 405 at an opposite second end. The main body 402 defines a plurality of liquid inlets 403 in a sidewall. The tobacco liquid in the liquid chamber 303 can permeate the liquid conducting body 402 via the liquid inlets 403.
In the present embodiment, both of the liquid conducting body 402 and the heating device 200 are arranged vertically. The liquid conducting body 402 surrounds the heating part 201. An axial direction of the heating part 201 is coaxial with an axial direction of the liquid conducting body 402.
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.
