Patent Application
20240349799
The present disclosure generally relates to atomization and vaporizing devices, and more particularly, to an atomization core of an electronic cigarette device.
Electronic cigarette (also known as “E-cigarette”), or vaping, devices can be used to deliver nicotine, cannabis (THC, CBD), flavorings, chemicals, and other substances. These devices are known by many different names and come in many shapes, sizes and device types. These devices may also be referred to as “E-cigs”, “Vapes”, “Vape pens,” “dab pens,” “dab rigs,” “Tanks,” “Mods,” “Pod-Mods,” and the like. Use of e-cigarette, or vaping, products is sometimes referred to as “vaping.”
Typically, a conventional e-cigarette device or electronic cigarette device includes several basic components: a cartridge (also referred to as a reservoir or pod), an atomizer (or atomizer core) including a heating element, a power source (e.g., a battery), and a mouthpiece. The cartridge (or reservoir or pod) can hold various substances. The cartridge may be pre-loaded with these substances, and sold with or separate from the rest of the e-cigarette device. One particular substance is a liquid solution (sometimes referred to as “e-liquid” or “e-juice”). In one particular example, the liquid solution may contain varying amounts of nicotine, cannabis (THC, CBD), flavorings, and/or other chemicals. Some conventional e-cigarette devices may not use a cartridge to hold the liquid solution. Instead, these e-cigarette devices include a reservoir built-into the device for containing the liquid solution, and into which the liquid solution can be filled. In many e-cigarette devices, puffing by a user results in an airflow entering the electronic cigarette device. As the air flows into the electronic cigarette device, the generated airflow will trigger an airflow sensor, and thereby activate the heating element of the atomizer. The electric heating element, disposed within an atomization channel of the atomizer core, starts to heat the e-liquid, and generate aerosol or vapor, which then flows out through the atomization channel under the drive of the airflow, and the resulting aerosol or vapor travels to the mouthpiece where the aerosol or vapor is then inhaled by the user.

With reference to
The ceramic atomization core 124 is disposed within a lower end of the atomization tube 122. The atomization tube 122 includes an inner, generally cylindrical atomization channel 133. While the atomization channel 133 is illustrated as being generally cylindrical, the atomization channel 133 can have other shapes including polygonal shapes where the atomization channel could have three (3) or more sides. The inner atomization channel 133 is configured to provide a path for discharge of aerosol or vapor to the upper cap 121. The aerosol or vapor is generated by heating and atomization of e-liquid 400 by the ceramic atomization core 124. The upper cap 121 includes a mouthpiece portion 135 for engagement with a user's mouth during use of the electronic cigarette assembly 20. The upper cap 121 also includes a channel or passage 136 defining a path to the atomization tube 122 through which the aerosol or vapor passes through the upper cap 121 to a user's mouth for subsequent inhalation. One end of the channel or passage 136 is open at the mouthpiece portion 135 and one end of the channel or passage 136 is open to the atomization tube 122 through a guide portion 140 of the upper cap 121. The open upper end of the atomization tube 122 extends into the guide portion 140 of the upper cap 121 in communication with the channel or passage 136 such that vaporized liquid or smoke passes from the atomization tube 122 into the channel or passage 136 for subsequent inhalation by the user as the mouthpiece portion 135 is in communication with the atomization channel 133.
The atomization tube 122 includes at least one e-liquid inlet hole 1221 corresponding to the ceramic atomization core 124. The e-liquid inlet hole 1221 allows e-liquid 400 in the e-liquid storage chamber or cavity 131 to enter the ceramic atomization core 124 and move towards an electric heating element 150 for atomization into aerosol or vapor. As mentioned above, the “e-liquid” or “e-juice” 400 is a liquid solution that may contain varying amounts of various substances (alone or in combination) that can include, without limitation, nicotine, cannabis (e.g., THC, CBD), flavorings, and/or other chemicals.
As shown in
The electric heating element 150 may come in various forms including, but not limited to two (2) identical electric heating element bodies connected in parallel together and soldered at two ends. In one illustrative embodiment, the size of a soldered dot left after soldering cannot be more than 0.35 mm (as the larger the soldered dot, the easier it becomes for a portion of the soldered dot to contact an adjacent heating coil of the electric heating element 150, and cause a short circuit).
As shown in
The e-liquid 400 is transferred from the e-liquid storage chamber or cavity 131 to the e-liquid guide cotton 123 through the e-liquid inlet hole 1221 and finally into the ceramic core 124. As seen in
As seen in
The respective outer diameters of the protrusion or first portion 1241 and the main body or second portion 1242 can be adjusted as needed as long as the outer dimension of the protrusion or first portion 1241 is smaller than the outer diameter of the main body or second portion 1242.
As seen in
As seen in
The atomizer core 124 provides various advantages, such as prolonged service life as compared with the conventional cylindrical atomizer 24, in which the e-liquid vapor forms the e-liquid film to block the atomization channel 33, resulting in problems such as short service life of the atomizer. Furthermore, e-liquid usage efficiency is improved by the atomizer core 124 since unused e-liquid can be re-used by the ceramic core 124.
In addition, the claimed invention is not limited in size and may be constructed in various sizes in which the same or similar principles of operation as described above would apply. Furthermore, the figures (and various components shown therein) of the specification are not to be construed as drawn to scale.
The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. Throughout this specification the word “comprise”, or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps. In other words, unless explicitly stated to the contrary, embodiments “comprising” or “having” an element or a plurality of elements having a particular property can include additional elements not having that property. In other words, the terms “comprises,” “comprising,” “including,” and “having,” are inclusive and therefore specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. In other words, the use of “including,” “comprising,” “having,” “containing,” “involving,” and variations thereof, is meant to encompass the items listed thereafter and additional items. Further, references to “one embodiment” or “one implementation” are not intended to be interpreted as excluding the existence of additional embodiments or implementations that also incorporate the recited features. The term “exemplary” is intended to mean “an example of”.
As used herein, the singular forms “a”, “an” and “the” may be intended to include the plural forms as well, unless the context clearly indicates otherwise. In other words, an element or step recited in the singular and preceded by the word “a” or “an” should be understood as not necessarily excluding the plural of the elements or steps. Further, references to “one embodiment” or “one implementation” are not intended to be interpreted as excluding the existence of additional embodiments or implementations that also incorporate the recited features. Thus, when introducing elements of aspects of the disclosure or the examples thereof, the articles “a,” “an,” “the,” and “said” are intended to mean that there are one or more of the elements. In other words, the indefinite articles “a”, “an”, “the”, and “said” as used in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.” The use of the expression “at least” or “at least one” suggests the use of one or more elements or ingredients or quantities, as the use may be in the embodiment of the disclosure to achieve one or more of the desired objects or results.
The numerical values mentioned for the various physical parameters, dimensions or quantities are only approximations and it is envisaged that the values higher/lower than the numerical values assigned to the parameters, dimensions or quantities fall within the scope of the disclosure, unless there is a statement in the specification specific to the contrary. Any range or value given herein can be extended or altered without losing the effect sought, as will be apparent to the skilled person.
When an element or layer is referred to as being “on”, “engaged to”, “connected to” or “coupled to” another element or layer, it may be directly on, engaged, connected or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to”, “directly connected to” or “directly coupled to” another element or layer, there may be no intervening elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
In the description of the present invention, several means one or more, a plurality of means more than two, greater than, less than, more than, and the like are understood as not including this number, while above, below, within, and the like are understood as including this number. If there are the descriptions of first and second, it is only for the purpose of distinguishing technical features, and should not be understood as indicating or implying relative importance, implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.
In the description of the present invention, it should be noted that the terms “installation”, “connected” and “connection” if any shall be understood in a broad sense unless otherwise specified and defined. For example, they may be fixed connection, removable connection or integrated connection; may be mechanical connection or electrical connection; and may be direct connection, or indirect connection through an intermediate medium, and connection inside two elements. The specific meanings of the above terms in the present invention can be understood in a specific case by those of ordinary skills in the art.
While various spatial and directional terms, such as “up”, “down”, “front”, “rear”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “upper,” “lower,” and the like are used to describe embodiments and implementations of the present disclosure, it is understood that such terms are merely used with respect to the orientations shown in the drawings. The orientations can be inverted, rotated, or otherwise changed, such that a top side becomes a bottom side if the structure is flipped 180 degrees, becomes a left side or a right side if the structure is pivoted 90°, and the like. In other words, spatially relative terms, such as “inner,” “outer,” “beneath”, “below”, “above”, “lateral”, “longitudinal” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the example term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
In the description of the present invention, it should be understood that the orientation or position relationship indicated by the terms is based on the orientation or position relationship shown in the accompanying drawings, it is only for the convenience of description of the present invention and simplification of the description, and it is not to indicate or imply that the indicated device or element must have a specific orientation, and be constructed and operated in a specific orientation. Therefore, the terms shall not be understood as limiting the present invention.
As used herein, a structure, limitation, or element that is “configured to” perform a task or operation is particularly structurally formed, constructed, or adapted in a manner corresponding to the task or operation. For purposes of clarity and the avoidance of doubt, an object that is merely capable of being modified to perform the task or operation is not “configured to” perform the task or operation as used herein.
Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described above. Rather, the specific features and acts described above are disclosed as example forms of implementing the claims.
It will be understood that the benefits and advantages described above can relate to one embodiment or can relate to several embodiments. The embodiments are not limited to those that solve any or all of the stated problems or those that have any or all of the stated benefits and advantages. It will further be understood that reference to ‘an’ item refers to one or more of those items.
The order of execution or performance of the operations in examples of the disclosure illustrated and described herein is not essential, unless otherwise specified. That is, the operations can be performed in any order, unless otherwise specified, and examples of the disclosure can include additional or fewer operations than those disclosed herein. For example, it is contemplated that executing or performing a particular operation before, contemporaneously with, or after another operation (e.g., different steps, etc.) is within the scope of aspects and implementations of the disclosure. In other words, the method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order discussed or illustrated, unless specifically identified as an order of performance. It is also to be understood that additional or alternative steps may be employed.
The phrase “one or more of the following: A, B, and C” means “at least one of A and/or at least one of B and/or at least one of C.” The phrase “and/or”, as used in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
As used in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used shall only be interpreted as indicating exclusive alternatives (i.e., “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of” “only one of” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.
As briefly discussed above, as used in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
Use of ordinal terms such as “first,” “second,” “third,” etc., in the claims to modify a claim element does not by itself connote any priority, precedence, or order of one claim element over another or the temporal order in which acts of a method are performed. Ordinal terms are used merely as labels to distinguish one claim element having a certain name from another element having a same name (but for use of the ordinal term), to distinguish the claim elements.
Having described aspects of the disclosure in detail, it will be apparent that modifications and variations are possible without departing from the scope of aspects of the disclosure as defined in the appended claims. As various changes could be made in the above constructions, products, and methods without departing from the scope of aspects of the disclosure, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
It is to be understood that the above description is intended to be illustrative, and not restrictive. For example, the above-described embodiments (and/or aspects thereof) can be used in combination with each other. In addition, many modifications can be made to adapt a particular situation or material to the teachings of the various embodiments of the disclosure without departing from their scope. While the dimensions and types of materials described herein are intended to define the parameters of the various embodiments of the disclosure, the embodiments are by no means limiting and are example embodiments. Many other embodiments will be apparent to those of ordinary skill in the art upon reviewing the above description. The scope of the various embodiments of the disclosure should, therefore, be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. In the appended claims, the terms “including” and “in which” are used as the plain-English equivalents of the respective terms “comprising” and “wherein.” Moreover, the terms “first,” “second,” and “third,” etc. are used merely as labels, and are not intended to impose numerical requirements on their objects. Further, the limitations of the following claims are not written in means-plus-function format and are not intended to be interpreted based on 35 U.S.C. § 112 (f), unless and until such claim limitations expressly use the phrase “means for” followed by a statement of function void of further structure.
This written description uses examples to disclose the various embodiments of the disclosure, including the best mode, and also to enable any person of ordinary skill in the art to practice the various embodiments of the disclosure, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the various embodiments of the disclosure is defined by the claims, and can include other examples that occur to those persons of ordinary skill in the art. Such other examples are intended to be within the scope of the claims if the examples have structural elements that do not differ from the literal language of the claims, or if the examples include equivalent structural elements with insubstantial differences from the literal language of the claims.
The above description presents the best mode contemplated for carrying out the present invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains to make and use this invention. This invention is, however, susceptible to modifications and alternate constructions from that discussed above that are fully equivalent. Moreover, features described in connection with one embodiment of the invention may be used in conjunction with other embodiments, even if not explicitly stated above. Consequently, this invention is not limited to the particular embodiments disclosed. On the contrary, this invention covers all modifications and alternate constructions coming within the spirit and scope of the invention as generally expressed by the following claims, which particularly point out and distinctly claim the subject matter of the invention.
The following claims are thus to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can be obviously substituted and also what essentially incorporates the essential idea of the invention. Those skilled in the art will appreciate that various adaptations and modifications of the just-described preferred embodiment can be configured without departing from the scope of the invention.
