Patent Application

The present invention relates to electronic cigarettes, and particularly to a heating device, an atomizing unit, an atomizer and an electronic cigarette using same.
A typical atomizer includes a liquid conducting body and a heating element in tight contact with the liquid conducting body. The heating element is configured for heating tobacco liquid in the liquid conducting body to form aerosol. However, a contact surface between the liquid conducting body/the heating element and other components is usually large. Accordingly, a large part of heat is lost due to thermal conduct. Therefore, efficiency of the atomizer may be low.
What are needed, therefore, are a heating device, an atomizing unit, an atomizer and an electronic cigarette using same, which can overcome the above shortcomings.
The present disclosure relates to a heating device for heating tobacco liquid. The heating device includes a heating element, and a liquid conducting body configured for guiding the tobacco liquid to the heating element. The liquid conducting body includes a main body and at least one liquid conducting arm extending from the main body. The heating element is inserted in the main body, and is integrally formed with the main body. The at least one liquid conducting arm and the main body are made of micro-porous material.
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 micro-porous material is micro-porous ceramic, the liquid conducting arms 102 and the main body 101 are integrally formed, and the heating element 104 is sintered together with the micro-porous ceramic and inserted into the main body 101. During sintering process, pore-foaming agent is added. It is to be understood that, in other embodiments, the liquid conducting body 103 may be made of porous metal.
Quite usefully, the main body 101 centrally defines a first aerosol passage 105 extending through the main body 101, and the heating element 104 is arranged in the first aerosol passage 104. The heating element 104 is a spiral heating wire, and the heating wire is sintered on an inner surface of the main body 101. The heating wire is connected to electrodes of a power supply via two leads 107. The heating wire is configured for heating tobacco liquid permeating from the liquid conducting arms 102 and the main body 101 to form aerosol, which is expelled via the first aerosol passage 105. Alternatively, the heating element 104 may be a resistance layer or a metallic pattern formed on an internal surface of the main body 101. Further, the liquid conducting arms 102 defines a plurality of blind holes 106. The blind holes increases a contact area between the liquid conducting arms 102 and the tobacco liquid, and enhances liquid conducting efficiency of the liquid conducting body 103. The blind holes 106 are not in direct communication with the first aerosol passage 105.

Quite usefully, a liquid storing layer 206 is wrapped around the bracket 209, and is configured for absorbing tobacco liquid. Quite usefully, the liquid storing layer 106 is made of fiber cotton. The fiber cotton is arranged between the housing 201 and the bracket 209. The tobacco liquid goes in via the liquid inlet 204, and is then absorbed by the liquid storing layer 206. The liquid conducting arms 102 absorb the tobacco liquid from the liquid storing layer 206. The liquid storing layer 206 can buffer the tobacco liquid. Further, a filter net 205 is arranged between the heating device 10 and the air outlet 203. The filter net 205 is configured for preventing large liquid drops, which are not atomized adequately, from entering the mouthpiece.

In detail, a mouthpiece 302 is provided at an end of the shell 301, and an electrode assembly 303 is provided at an opposite end. The electrode assembly 303 includes a plurality of screws for connecting with a power supply. The electrode assembly 303 abuts against the electrical connection part 208 of the atomizing unit 20, thus achieving electrical connection with the heating element 104. An air pipe 310 is arranged in the shell 301, communicating the mouthpiece 302 and the air outlet 203 of the atomizing unit 20. The electrode assembly 303 and the atomizing unit 20 are detachably connected to the shell 301 via screw threads, thus sealing the liquid chamber 309. A top end of the atomizing unit 20 is coupled in the air pipe 310, and aerosol in the first and the second aerosol passage 105, 108 goes in the mouthpiece 302 via the air pipe 310.
Quite usefully, a first air inlet 306 and a first adjusting ring 307 are provided at an end of the atomizer 30 adjacent to the electrode assembly 303. The first adjusting ring 307 is configured for adjusting an air inflow of the first air inlet 306. The first air inlet 306 is in communication with the air inlet 202 of the atomizing unit 20. An amount of aerosol can be changed by adjusting the first adjusting ring 307.
A second air inlet 304 and a second adjusting ring 305 are provided at an end of the atomizer 30 adjacent to the mouthpiece 302. The second air inlet 304 is in communication with the mouthpiece 302. The second adjusting ring 305 is configured for adjusting an air inflow of the second air inlet 304. A concentration of the aerosol can be changed by adjusting the second adjusting ring 305.
