Patent Application
20160206006
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 heating assembly having a heating element and a liquid conducting body. The liquid conducting body is configured for absorbing tobacco liquid. The heating element is configured for heating tobacco liquid in the liquid conducting body to form aerosol.
In a typical electronic cigarette, a temperature of the heating assembly is not detected. Therefore, it is difficult to precisely control the temperature of the heating assembly, and to keep a stable amount of aerosol generated by the electronic cigarette.
What is needed, therefore, is an atomizer and an electronic cigarette using same, which can overcome the above shortcomings.
An atomizer includes a housing, a liquid chamber defined in the housing, a heating assembly in the housing, an air passage, and two electrodes. The liquid chamber is configured for storing tobacco liquid. The heating assembly includes a liquid conducting body and a heating element. The liquid conducting body is configured for absorbing the tobacco liquid from the liquid chamber. The heating element is in contact with the liquid conducting body. The heating element is configured for heating the tobacco liquid to form aerosol. The air passage allows the aerosol to flow out of the atomizer. The two electrodes are arranged at one end of the housing, and electrically connected to two opposite ends of the heating element. The atomizer further includes a temperature sensor configured for sensing a temperature of the heating assembly.
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
The heating assembly 111 includes a liquid conducting body 1112 and a heating element 1111. The liquid conducting body 1112 is configured (i.e., structured and arranged) for absorbing tobacco liquid. The heating element 1111 is in contact with the liquid conducting body 1112, and configured for heating the tobacco liquid absorbed in the liquid conducting body 1112 to form aerosol. A first electrode 131 and a second electrode 132 are arranged at a first end of the housing 110, and a mouthpiece 120 is provided at an opposite second end of the housing 110. The mouthpiece 120 is in communication with the air passage 114. A temperature sensor 112 is further arranged in the housing 110. The temperature sensor 112 is configured for detecting a temperature of the heating assembly 111. A feedback terminal 133 is electrically connected with the temperature sensor 112. The feedback terminal 133 is provided at the first end of the housing 110.
In the present embodiment, the temperature sensor 112 is made of material of positive temperature coefficient (PTC). The PTC material may be nickel chromium alloy, or nickel silicon alloy. Quite usefully, the temperature sensor 112 includes a PTC thermistor.
In the present embodiment, the atomizer 110 includes two heating assemblies 111, and each heating assembly 111 includes the heating element 1111 and the liquid conducting body 1112. The temperature sensor 112 is arranged in one of the two liquid conducting bodies 1112. The liquid conducting body 1112 is made of ceramic material or glass fiber material. The liquid conducting body 1112 defines a through hole 1113 extending axially. The temperature sensor 112 is located in a middle of the through hole.
