Description

Technical Field

[0001] The present disclosure relates generally to atomization and vaporization devices, and more particularly, to an atomization tube of an electronic cigarette device. Background Art

[0002] Electronic cigarettes (also called “e-cigarettes”) or vaping devices can be used to deliver nicotine, flavors, chemicals, and other substances. These devices go by many different names and come in many shapes, sizes, and device types. These devices may also be called “e-cigarettes,” “vapes,” “vape pens,” “dab pens,” “dab rigs,” “Tanks,” “Mods,” “Pod-Mods,” and more. Using an e-cigarette or vaping product is sometimes called “vaping.”

[0003] Typically, a conventional electronic cigarette device or e-cigarette device includes a number of basic components: a cartridge (also known as a reservoir or pod), a heating element or heating device (also known as an atomizer), a power source (e.g., a battery), and a mouthpiece. The cartridge (or reservoir or pod) can contain a variety of substances. The cartridge can be preloaded with these substances and sold together with or separately from the rest of the electronic cigarette device. A special substance is a liquid solution (sometimes referred to as "e-liquid" or "e-juice"). In a specific example, the liquid solution can contain different amounts of nicotine, flavors, and / or other chemicals. Some conventional electronic cigarette devices may not use a cartridge to hold a liquid solution. Instead, these electronic cigarette devices include a reservoir built into the device for holding a liquid solution, and the liquid solution can be filled into the reservoir. In many electronic cigarettes, inhalation activates a battery-powered heating element, which vaporizes the liquid in the cartridge. The user then inhales the generated aerosol or vapor (called steaming) via the mouthpiece.

[0004] In conventional electronic cigarettes, due to the presence of excess electronic liquid, the electronic liquid absorbed by the atomizer from the electronic liquid reservoir may easily drip and flow out of the atomizer. During storage and transportation, due to weather conditions such as high temperature and extreme cold, the air pressure in the electronic liquid reservoir may be too high, causing the electronic liquid to flow into the atomization channel of the atomizer due to the high air pressure in the electronic liquid reservoir, and then flow out of the electronic cigarette device atomizer to cause pollution and waste.

[0005] Therefore, there is a need for an improved electronic cigarette device. There is a need for an improved electronic cigarette device that can reduce the waste of electronic cigarette liquid. There is a need for an improved electronic cigarette that can reduce the air pressure in the electronic cigarette liquid storage chamber. There is also a need for an improved electronic cigarette device that is easier to manufacture, assemble, disassemble, adjust and maintain. The present invention meets these needs and provides other related advantages. Summary of the invention

[0006] The present invention provides an improved electronic cigarette device. The present invention provides an improved electronic cigarette device that can reduce the waste of electronic cigarette liquid. The present invention provides an improved electronic cigarette that can reduce the air pressure in the electronic cigarette liquid storage chamber. The present invention provides an improved electronic cigarette device that is easier to manufacture, assemble, adjust and maintain. The present invention meets these needs and provides other related advantages.

[0007] According to one embodiment of the present invention, the atomizer tube is configured to be disposed in a liquid storage chamber of an electronic cigarette device. The atomizer tube includes a tubular first portion configured to receive a heating core and a tubular second portion. The tubular first portion includes an inlet hole and an exhaust hole, and liquid enters the tubular first portion from the liquid storage chamber through the inlet hole to contact the heating core.

[0008] According to another embodiment of the invention, the exhaust holes are arranged on the tubular first portion, adjacent to an upper portion of the heating core.

[0009] According to yet another embodiment of the present invention, the inlet opening is provided on the tubular first portion towards the bottom of the liquid storage chamber.

[0010] According to yet another embodiment of the present invention, the tubular first portion comprises cotton wrapped around the heating core.

[0011] According to another embodiment of the present invention, the atomizer tube further comprises a blocking member disposed in the tubular first portion between the heating core and the tubular second portion.

[0012] According to yet another embodiment of the present invention, the exhaust hole is provided on the tubular first portion adjacent to a portion of the blocking member.

[0013] According to yet another embodiment of the present invention, the blocking member comprises an exhaust portion and an abutment portion. The abutment portion is configured to abut against an inner wall of the atomization tube.

[0014] According to an additional embodiment of the invention, the outer diameter of the abutment portion is greater than the outer diameter of the exhaust portion.

[0015] According to yet another additional embodiment of the present invention, a distance between an outer diameter of the exhaust portion and an inner wall of the atomizing tube surrounding the exhaust portion defines a gap between the exhaust portion and a portion of the atomizing tube surrounding the exhaust portion.

[0016] According to yet another additional embodiment of the present invention, abutment of the abutment portion against the inner wall of the atomization tube aligns the exhaust portion with the exhaust hole, and thus gas flows between the exhaust portion and the exhaust hole.

[0017] According to an additional embodiment of the invention, the blocking member comprises a central passage through which the gas passes from the heating core into the tubular second portion.

[0018] According to another embodiment of the present invention, the blocking member further includes a protruding portion and a chamfered portion provided between the protruding portion and the exhaust portion.

[0019] According to another embodiment of the present invention, the protruding portion has an outer diameter that is smaller than an outer diameter of the exhaust portion.

[0020] According to an embodiment of the present invention, liquid condenses on at least a portion of at least one of the protruding portion and the chamfered portion.The condensed liquid then moves along a portion of the outer diameter of the exhaust portion toward the chamfered portion.

[0021] According to an additional embodiment of the invention, the heating core is configured to evaporate liquid and the tubular second portion is configured to direct the evaporated liquid upwards.

[0022] One advantage of the vent hole in the atomizer tube is that it helps prevent a large amount of high temperature steam from accumulating at the closed end of the atomizer chamber and causing the e-liquid to flow into the atomization channel of the atomizer tube and then out of the atomizer due to the high air pressure in the e-liquid storage chamber, thereby causing pollution and waste. The vent hole provides an air passage that provides communication between the atomizer chamber and the steam discharge channel and reduces (even if it cannot eliminate) the high air pressure in the e-liquid storage chamber.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0038] Reference Figure 1-Figure 11 , an embodiment of the present invention provides an improved electronic cigarette. According to an embodiment of the present invention, Figure 1-Figure 6As shown, the electronic cigarette assembly 20 includes an atomizer body (or atomizer body assembly) 100 and a mouthpiece body (or mouthpiece assembly) 200. The atomizer body 100 includes an atomizer housing 101, an electronic cigarette liquid cup holder or an electronic cigarette liquid cup holder 110 and an atomizer protective cover 120. The electronic cigarette liquid cup holder 110 includes a holder housing (or housing or support) 111, a battery assembly 113, a lower fixed base 114, a terminal 115, an atomizer tube 116, a heating assembly or an atomizer core (or an atomizer core) 118 and a lower sealing member 117. The lower fixed base 114 is a circuit board, which is used as a mounting member for various components (including but not limited to the atomizer core 118 and the battery assembly 113). The electrode base 1165 is used for conducting electricity. Each electrode base 1165 is electrically connected to a wire or a conductor (not shown for clarity), and then electrically connected to the lower fixed member (or circuit board) 114 through the wire. The atomizing core or heating core 118 is electrically connected to the electrode base 1165. The atomizing core 118 is connected to the battery assembly 113 through the fixing base 114 to form a circuit. The charging terminal 115 is used to charge the battery assembly 113. The charging terminal 115 is riveted to the lower fixing base 114 by a lead wire. The lower sealing member 117 is used to support other elements and to locate the position tolerance of other elements. The lower sealing member 117 includes a wire hole, and the pin of the atomizing core 118 passes through the wire hole. The lower sealing member 117 further includes an air hole to allow the airflow to pass through the microphone when entering the electronic cigarette device 20 from the outside of the electronic cigarette device 20. The holder housing (or shell) 111 of the electronic cigarette liquid cup holder 110 is further provided with an electronic cigarette liquid storage tube 119 (which partially defines the electronic cigarette liquid storage chamber or electronic cigarette liquid storage chamber 121) and a battery compartment 123 (the battery 113 is arranged therein). The holder housing 111 is mounted on the lower fixed base 114. The sealing ring 1164 is sleeved around the lower sealing member 117 to prevent the electronic cigarette liquid from leaking from the edge and corroding the circuit board 114. The atomizer protective cover 120 can be made of various materials, including but not limited to plastics (e.g., thermoplastics, thermoelastic plastics, thermosetting plastics, etc.), silicone, etc. The atomizer protective cover 120 (or a portion thereof) can be transparent, translucent or opaque.

[0039] The electronic cigarette liquid cup holder 110 includes an electronic cigarette liquid storage chamber 121 defined by a lower sealing member 117, a lower fixed base 114, an electronic cigarette liquid storage tube 119 and a holder housing 111. As described above, "electronic cigarette liquid" or "electronic cigarette juice" is a liquid solution that may contain various substances (alone or in combination) in different amounts, which may include but are not limited to nicotine, flavors and / or other chemicals. The electronic cigarette liquid storage chamber 121 is designed so that the electronic cigarette liquid is disposed in the electronic cigarette liquid storage chamber 121. According to design requirements, the storage capacity of the electronic cigarette liquid storage chamber 121 can be configured as needed (e.g., 0.5ml, 1ml, 2ml, etc.). The outer wrapping cotton 112 is disposed around the atomizing core or heating core 118 in the atomizing tube 116 to absorb the electronic cigarette liquid subsequently introduced into the atomizing tube 116. The atomizing tube 116 is usually disposed in the electronic cigarette liquid storage chamber 121. The electronic cigarette liquid enters the interior of the atomizer tube 116 from the electronic cigarette liquid storage chamber 121 through at least one electronic cigarette liquid inlet hole or electronic cigarette liquid guide hole 142 and reaches the atomizer core 118 and is introduced into the atomizer core 116. The electronic cigarette liquid flows obliquely from the bottom of the electronic cigarette liquid storage chamber 121 to the electronic cigarette liquid guide hole 142, and then enters the atomizer tube 116 from the electronic cigarette liquid guide hole 142, and the ceramic atomizer core 118 heats and atomizes the electronic cigarette liquid in the atomizer tube. The holder housing 111 includes a container 124, and the bottom portion of the atomizer tube 116 is disposed in the container, so that the electronic cigarette liquid guide hole 142 is disposed at or near the bottom of the electronic cigarette liquid storage chamber 121.

[0040] The mouthpiece body (or mouthpiece assembly) 200 includes an upper fixed base 210 and an upper sealing member 212. The mouthpiece protective cover 220 is sleeved on the periphery of the mouthpiece body 200. The mouthpiece protective cover is used to seal the opening of the mouthpiece body 200 to reduce / prevent foreign matter from entering the upper fixed base 210. The upper sealing member 212 provides an overall seal between the upper fixed base 210 and the body 100. The upper sealing member 212 can be made of various materials (including but not limited to silicone, plastic, etc.). The upper sealing member 212 is provided with at least one (1) blind hole or e-liquid filling port 2121, which is configured to provide a passage to the e-liquid storage chamber 121 to fill the e-liquid storage chamber 121 with e-liquid (not shown for clarity). The e-liquid sealing member 2122 is disposed in the e-liquid filling port 2121 between the ends of the e-liquid sealing port 2121 to seal the e-liquid filling port 2121. The e-liquid sealing member (or thin film diaphragm) 2122 can be punctured to fill the e-liquid into the e-liquid storage chamber 121. The e-liquid filling port 2121 can be used as a guide for the e-liquid injection needle (when the needle is used to add the e-liquid to the e-liquid storage chamber 121). The thickness of the thin film diaphragm 2122 is about one millimeter to about five millimeters (1mm-5mm). Preferably, the thickness of the film is about two millimeters to about three millimeters (2mm-3mm). During the injection of the e-liquid, the injection needle is inserted through the thin film diaphragm 2122 for injecting the e-liquid into the e-liquid storage chamber 121. When the injection needle is pulled out, the film diaphragm 2122 will return to its original state to seal, and the electronic cigarette liquid will not leak out of the electronic cigarette liquid storage chamber 121 through the film diaphragm 2122. The electronic cigarette liquid sealing member or the film diaphragm 2122 is made of various materials, including but not limited to colloid (which can be restored to its original state), silicone, latex, rubber, resin, or the like that can be restored to its original shape. The perforation in the film diaphragm 2122 is fully closed to the extent that the electronic cigarette liquid cannot be refilled from the electronic cigarette liquid storage chamber 121 into the upper fixed base 210.

[0041] The upper fixed base 210 is arranged at the other end of the electronic cigarette liquid storage tube 121. The atomization tube 116 is arranged on the lower sealing member 117, and a hollow smoke guide tube 1161 is provided in the direction of the mouthpiece body 200. The smoke guide tube 1161 provides a path for the vaporized electronic cigarette liquid to travel to the mouthpiece body 200 for the user to inhale. The atomization channel is thus formed in the smoke guide tube 1161. The heating core 118 is made of porous ceramic and is embedded with an electric heating element arranged around the central atomization channel. The electric heating element is connected to the lower fixed base 114 through a hole on the lower sealing member 117. The lower sealing member 117 is provided with a microphone 1151 used as an air flow sensor. The microphone 1151 is arranged between the lower fixed base 114 and the lower sealing member 117. The air hole is arranged around the microphone 1151, and the air hole is communicated with the atomization channel.

[0042] The atomizer housing 101 may include a window or aperture 160, the size and shape of which allows the user to see various components of the electronic cigarette liquid cup holder 110 when the housing 111 is covered by the atomizer housing 101. The atomizer housing 101 can be made of various materials, including but not limited to plastics (e.g., thermoplastics, thermoelastic plastics), etc. The atomizer housing 101 (or a portion thereof) can be transparent, translucent or opaque. The housing 111 of the electronic cigarette liquid cup holder 110 can be made of various materials, including but not limited to plastics (e.g., thermoplastics, thermoelastic plastics), etc. The housing 111 of the electronic cigarette liquid cup holder 110 (or a portion thereof) can be transparent, translucent or opaque.

[0043] The electronic cigarette liquid cup holder 110 is further provided with a support column 1112, which is used to position the mouthpiece body 200 (and provide additional strength to resist excessive stretching and bending). The support column 1112 extends through the aperture 1113 of the upper sealing member 212 and at least partially extends into the hole or guide 1114 of the upper fixed base 210, which is sized and shaped to receive the support column 1112. The aperture 1113 of the sealing member 212 is sized and shaped to receive at least a portion of the hole or guide 1114 of the upper fixed base 210, and the hole or guide 1114 is sized and shaped to receive the support column 1112. The extension of the support column 1112 through the aperture 1113 and into the hole or guide 1114 helps the alignment and positioning of the smoke guide tube 1161 and the support column 1112 with the mouthpiece protective cover 220 and the upper fixed base 210.

[0044] The upper sealing member 212 is disposed on one side of the mouthpiece body 200 (i.e., the side facing the atomizer body 100). The upper portion of the upper sealing member 212 is at least partially disposed within the upper fixed base 210. The mouthpiece body 200 includes an e-liquid filling channel or passage 2124, which defines a path to the e-liquid filling port 2121. The smoke guide tube 1161 of the atomizer tube 116 extends through the orifice 2120 of the upper sealing member 212, so that the vaporized liquid or smoke enters the passage 2124 from the smoke guide tube 1161 for subsequent inhalation by the user. The upper fixed base 210 includes an orifice or guide tube 2102, wherein the guide tube 1161 of the atomizer tube 116 extends into the orifice 2102. The extension of the smoke guide tube 1161 through the openings 2120, 2102 facilitates the alignment and positioning of the smoke guide tube 1161 with the mouthpiece protective cover 220 and the upper fixed base 210. The smoke guide tube 1161 and the support column 1112 are respectively disposed at both ends to improve the stability of the electronic cigarette device 20.

[0045] The upper sealing member 212 is fixed to the e-liquid cup holder 110 through the mouthpiece body 200. The mouthpiece body 200 is removably mounted and connected to the e-liquid cup holder 110 by means of a snap-fit ​​structure, etc., so that after removing the mouthpiece body 200 and the upper sealing member 212, the e-liquid can be directly filled into the e-liquid storage chamber 121. In alternative solutions, various other fastening mechanisms can be used, including but not limited to press-fit engagement, clips, magnets embedded at both ends for connection, etc. In another alternative solution, the main body 100 and the mouthpiece body 200 are fixed to each other or otherwise permanently engaged with each other.

[0046] As described above, the outer wall of the atomizer tube 116 is provided with an electronic cigarette liquid guide hole 142, and the electronic cigarette liquid guide hole is configured to allow the electronic cigarette liquid to enter the interior of the atomizer tube 116 to atomize the electronic cigarette liquid through the heating core 118. The atomizer tube 116 is fixed to the lower fixing base 114, and the lower fixing base 114 is provided with an air guide hole, which is configured to allow gas (e.g., air) to pass through the air inlet of the atomizer tube 116 and enter the interior thereof. Similarly, the lower sealing member 117 has a corresponding air guide hole for allowing air to pass through the atomizer tube 116.

[0047] When the user smokes from the mouthpiece body 200, air pressure is generated, and the air flow sensor (i.e., microphone 1151) senses the air pressure difference, which in turn activates the electric heating element in the heating core 118 and generates heat. The electric heating element heats and evaporates the electronic cigarette liquid in the heating core 118 to form an aerosol. The aerosol and the gas (i.e., air) are sucked toward and through the mouthpiece body 200 through the smoke guide tube 1161 to be inhaled by the user. However, the electronic cigarette liquid may accumulate at one end of the heating core 118 to form an electronic cigarette liquid film to block the atomization channel of the heating core 118, which prevents the airflow inhaled by the user from passing through the electronic cigarette liquid film again, and the airflow sensor 1151 cannot sense the suction action, which further prevents the circuit of the heating core 118 from being triggered (i.e., the heating core 118 cannot perform the heating operation, and the entire atomizer cannot be used).

[0048] In order to prevent the accumulation of electronic cigarette liquid and reduce the possibility of clogging of the atomization channel, the atomization tube 116 further includes an air exhaust hole 141. The exhaust hole 141 is provided in the side wall of the atomization tube 116 to provide gas communication between the atomization tube 116 and the electronic cigarette liquid storage chamber 121 to balance the air pressure in the atomization chamber. Figure 4-Figure 6 As shown, the atomizer core includes an atomizer tube 116 and a heating core 118 (which may be a ceramic heating core) disposed in the atomizer tube 116. The outside of the ceramic heating core 118 is wrapped with a wrapping cotton 112. The wrapping cotton 112 wraps the ceramic heating core 118 and is arranged in the gap between the ceramic heating core 118 and the inner wall of the atomizer tube 116. The electronic cigarette liquid storage chamber 121 is connected to the mouthpiece assembly 200 via the atomizer tube 116, so that the air pressure in the electronic cigarette liquid storage chamber 121 is always balanced, thereby reducing the risk of electronic cigarette liquid leakage. The electronic cigarette liquid storage chamber 121 can be directly filled with electronic cigarette liquid, or an electronic cigarette liquid storage cotton (separate and different from the wrapping cotton 112) is provided inside, which is used to hold the electronic cigarette liquid (that is, the electronic cigarette liquid storage cotton absorbs the electronic cigarette liquid in the electronic cigarette liquid storage chamber 121). The exhaust hole 141 balances the air pressure in the electronic cigarette liquid storage chamber 121, and the air pressure balance in the electronic cigarette liquid storage chamber 121 reduces (even if it cannot prevent) the electronic cigarette liquid squeezed out of the electronic cigarette liquid storage chamber 121 due to the high pressure in the electronic cigarette liquid storage chamber 121. The electronic cigarette liquid storage chamber 121 can be supplemented with air through the exhaust hole 141 to make the electronic cigarette liquid flow more smoothly through the electronic cigarette liquid inlet hole 142. The ceramic heating core 118 is a hollow structure, and the ceramic heating core 118 is connected to the atmosphere through the exhaust hole 141, the smoke guide tube 1161 and the passage 2124, so the air pressure in the ceramic heating core 118 does not need to be balanced.

[0049] The electronic liquid inlet hole 142 and the exhaust hole 141 are arranged in the side wall of the atomizer tube 116. The exhaust hole 141 and the electronic liquid inlet hole 142 are located at positions corresponding to the ceramic heating core 118 and the wrapped cotton 112. The exhaust hole 141 is arranged toward the mouthpiece assembly 200, and the electronic liquid inlet hole 142 is arranged toward the bottom of the electronic liquid storage chamber 121. The wrapped cotton 112 is permeable to gas but impermeable to liquid. The electronic liquid inlet hole 142 is arranged near the end of the atomizer tube 116 away from the passage 2124 (or the mouthpiece). With the help of the exhaust hole 141, the air pressure balance in the atomizer tube 116 can be maintained, thereby preventing the electronic liquid from flowing into the atomization channel of the atomizer tube 116 due to the influence of the high air pressure in the electronic liquid storage chamber 121, and then flowing out of the atomizer core to cause pollution and waste. The electronic cigarette liquid is usually filled in the electronic cigarette liquid storage chamber 121, and the exhaust hole 141 is usually immersed below the liquid level of the electronic cigarette liquid. Since only air can pass through the exhaust hole 141, the electronic cigarette liquid cannot pass through the exhaust hole 141.

[0050] According to another embodiment of the present invention, Figure 7-Figure 11 As shown, the electronic cigarette device 30 is similar in operation and structure to Figure 1-Figure 6The electronic cigarette device 20 of the present invention has a significant difference in that the electronic cigarette device 30 further includes a substantially cylindrical blocking member 150 disposed inside the atomizing tube 116 at a position corresponding to the exhaust hole 141. The blocking member 150 includes an abutting component or abutting portion 152 abutting against the inner wall of the atomizing tube 116. The blocking member 150 further includes an exhaust component or an exhaust portion 151. The outer diameter of the abutting portion 152 of the blocking member 150 is greater than the outer diameter of the exhaust portion 151 of the blocking member 150. The difference between the outer diameter of the exhaust portion 151 and the inner diameter of the corresponding portion of the side wall of the atomizing tube 116 surrounding the exhaust portion 151 forms a gap between the outer diameter of the blocking member 150 at the exhaust portion 151 and the corresponding portion of the side wall of the atomizing tube 116 surrounding the exhaust portion 151. The exhaust portion 151 is arranged at the end of the abutting portion 152 away from the ceramic core 118. The abutment portion 152 abuts against the inner wall of the atomizer tube 116 and restricts the exhaust portion 151 to the position of the exhaust hole 141, so that gas, air, etc. can flow between the exhaust portion 151 and the exhaust hole 141 to communicate the ceramic heating core 118 with the electronic cigarette liquid storage chamber 121. The central channel 153 extends through the blocking member 150, which allows aerosol, evaporated electronic cigarette liquid, etc. to enter the smoke guide tube 1161 from the ceramic heating core 118 upward. Only air can pass through the air exhaust hole 141, and electronic cigarette liquid cannot pass through the air exhaust hole 141. The outer diameter of the abutment portion 152 is approximately the same as the inner diameter of the atomizer tube 116. The abutment portion 152 is tightly press-fitted with the atomizer tube 116, so that the blocking member 150 is fixed. The outer diameter of the exhaust portion 151 is slightly smaller than the inner diameter of the atomizer tube 116, so there is a gap between the exhaust portion 151 and the wall of the atomizer tube 116. The gap is formed to allow communication between the exhaust hole 141 and the atmosphere.

[0051] The blocking member 150 further includes a protruding part or a protruding portion 154 having an outer diameter smaller than the outer diameter of the exhaust portion 151. The blocking member 150 also includes a chamfered portion 1541 between the protruding portion 154 and the exhaust portion 151. During use of the electronic cigarette device 30, a portion of the electronic cigarette liquid cannot be completely discharged from the atomization tube 116, and the electronic cigarette liquid that is not sucked condenses on the upper portion of the blocking member 150 and the chamfered portion 1541. The electronic cigarette liquid is atomized in the atomization tube 116 to form aerosol, and a portion of the aerosol condenses on the wall of the atomization tube 116 to form condensate. Then, the condensate flows along the wall of the atomization tube 116 to the chamfered portion 1541. It should be noted that the width of the gap between the outer diameter of the exhaust portion 151 and the corresponding portion of the side wall of the atomization tube 116 surrounding the exhaust portion 151 is approximately 0.035 mm to approximately 0.055 mm, and the blocking member 150 is preferably liquid-impermeable and gas-impermeable, and is preferably made of a metal with stable chemical properties (e.g., iron, copper, aluminum, etc.).

[0052] The electronic cigarette liquid storage chamber 121 is connected to the electronic cigarette liquid filling channel or passage 2124 of the mouthpiece assembly 200 by means of the atomizer tube 116, so that the air pressure in the electronic cigarette liquid storage chamber 121 is always balanced, thereby reducing the risk of electronic cigarette liquid leakage. The electronic cigarette liquid storage chamber 121 can be directly filled with electronic cigarette liquid, or electronic cigarette liquid storage cotton for storing electronic cigarette liquid can be arranged inside. It should be noted that in order to prevent the electronic cigarette liquid from directly penetrating into the atomizer tube 116 through the exhaust port or exhaust hole 141, the electronic cigarette liquid storage cotton (not shown) can be arranged in the electronic cigarette liquid storage chamber 121, so that the electronic cigarette liquid in the electronic cigarette liquid storage chamber 121 is retained in the electronic cigarette liquid storage chamber 121 by the electronic cigarette liquid storage cotton. In place of cotton, other absorbent materials (for example, natural fibers capable of absorbing electronic cigarette liquid, synthetic fibers capable of absorbing electronic cigarette liquid (for example, polymethacrylate fibers, etc.), or a combination of natural fibers and synthetic fibers capable of absorbing electronic cigarette liquid) can also be used. In an alternative solution, the gap between the outer diameter of the exhaust portion 151 and the corresponding portion of the side wall of the atomizer tube 116 surrounding the exhaust portion 151 can be filled with cotton material, absorbent material, etc. Due to the cotton material, the e-liquid in the e-liquid storage chamber 121 cannot enter the atomizer tube 116, and the gas can freely pass through the e-liquid storage chamber 121 and the atomizer tube 116. The e-liquid usually fills the entire e-liquid storage chamber 121, and the exhaust hole 141 should be immersed below the liquid level of the e-liquid.

[0053] Furthermore, the claimed invention is not limited in size and can be constructed in various sizes, wherein the same or similar operating principles as described above will apply. In addition, the drawings of the specification (and the various components shown therein) should not be construed as being drawn to scale.

[0054] The terms used herein are only for the purpose of describing specific example embodiments, and are not intended to be limiting. Throughout the specification, the word "include" or variations such as "include" or "comprising" will be understood to illustrate the elements, wholes or steps, or element groups, whole groups or step groups stated, but do not exclude any other elements, wholes or steps, or element groups, whole groups or step groups. In other words, unless otherwise explicitly stated, embodiments that "include" or "have" one or more elements with a specific property may include additional elements that do not have that property. In other words, the terms "include", "include", "contain" and "have" are inclusive, thus specifying the existence of stated features, wholes, steps, operations, elements and / or parts, but do not exclude the existence or addition of one or more other features, wholes, steps, operations, elements, parts and / or combinations thereof. In other words, the use of "contain", "include", "have", "cover", "involve" and variations thereof means including the items and additional items listed thereafter. In addition, reference to "an embodiment" or "an implementation" is not intended to be interpreted as excluding the existence of additional embodiments or implementations that also incorporate the features. The term "exemplary" is intended to mean "an example of."

[0055] As used herein, the singular forms "one", "an" and "the" may also be intended to include plural forms, unless the context clearly indicates otherwise. In other words, an element or step described in the singular and preceded by the word "one" or "an" should be understood to not necessarily exclude multiple elements or steps. In addition, reference to "an embodiment" or "an implementation" is not intended to be interpreted as excluding the existence of additional embodiments or implementations that also incorporate the features. Therefore, when introducing elements of aspects of the present disclosure or examples thereof, the articles "one", "one", "the" and "said" are intended to indicate the presence of one or more elements. In other words, the indefinite articles "one", "one", "the" and "said" used in the specification and claims should be understood to mean "at least one" unless the opposite meaning is clearly indicated. The use of the expression "at least" or "at least one" illustrates the use of one or more elements or components or quantities, because the use can achieve one or more desired purposes or results in the embodiments of the present disclosure.

[0056] The numerical values ​​of various physical parameters, dimensions or quantities mentioned are only approximate values, and it is conceivable that values ​​above / below the numerical values ​​assigned to the parameters, dimensions or quantities fall within the scope of the present disclosure unless there is a specific statement to the contrary in the specification. It is clear to those skilled in the art that any range or value given herein can be expanded or changed without losing the effect sought.

[0057] 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 there may be intervening elements or layers. Conversely, 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. Other words used to describe the relationship between elements should be interpreted in a similar manner (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.

[0058] In the description of the present invention, multiple means one or more, a plurality means more than two, greater than, less than, more than, etc. are understood to exclude the number, while above, below, within, etc. are understood to include the number. If there is a description of the first and second items, it is only for the purpose of distinguishing the technical features and should not be understood as indicating or explaining the relative importance, implicitly indicating the number of the technical features represented or implicitly indicating the order of the technical features represented.

[0059] In the description of the present invention, it should be noted that the terms "installed", "connected to", and "connected" (if any) should be understood in a broad sense unless otherwise specified and defined. For example, they can be fixedly connected, removably connected, or integrally connected; can be mechanically connected or electrically connected; and can be directly connected, or indirectly connected through an intermediate medium, as well as the connection between two elements. Those skilled in the art can understand the specific meanings of the above terms in the present invention in specific situations.

[0060] Although various spatial and directional terms, such as "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "upper", "lower", etc., are used to describe embodiments and implementations of the present disclosure, it should be understood that these terms are used only with respect to the orientation shown in the drawings. The orientation can be reversed, rotated or otherwise changed so that if the structure is flipped 180 degrees, the top side becomes the bottom side, if the structure is pivoted 90°, it becomes the left or right side, and so on. In other words, for ease of description, spatial relative terms such as "inside", "outside", "below", "below", "above", "lateral", "longitudinal", etc. may be used herein to describe the relationship of one element or feature to another element or feature shown in the drawings. In addition to the orientation shown in the drawings, spatial relative terms may be intended to include different orientations of the device in use or operation. For example, if the device in the drawings is flipped, other elements or features described as "below" or "below" will be oriented as other elements or features "above". Therefore, the example term "below" can include both above and below directions. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0061] In the description of the present invention, it should be understood that the orientation or position relationship indicated by the term is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not mean or explain that the indicated device or element must have a specific orientation and be constructed and operated in a specific orientation. Therefore, these terms should not be understood to limit the present invention.

[0062] As used herein, a structure, limitation, or element that is "configured to" perform a task or operation is specifically structurally formed, constructed, or adapted in a manner corresponding to the manner of the task or operation. For clarity and avoidance of doubt, an object that is merely capable of being modified to perform a task or operation is not "configured to" perform a task or operation as used herein.

[0063] Although the subject matter has been described in language specific to structural features and / or methodological acts, it should 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.

[0064] It should be understood that the above benefits and advantages may relate to one embodiment, or may relate to multiple embodiments. The embodiments are not limited to embodiments that solve any or all of the problems described, or embodiments that have any or all of the benefits and advantages described. It should also be understood that reference to "an" item refers to one or more of those items.

[0065] Unless otherwise stated, the execution or implementation order of the operations in the examples of the disclosure shown and described herein is not necessary. That is, the operations can be performed in any order, unless otherwise stated, and the examples of the present disclosure may include more or less operations than the operations disclosed herein. For example, it is contemplated that before, simultaneously or after another operation (e.g., different steps, etc.), a specific operation is performed or executed within the scope of the aspects and embodiments of the present disclosure. In other words, the method steps, processes and operations described herein should not be interpreted as requiring them to be performed in the specific order discussed or shown, unless specifically identified as an execution order. It should also be understood that additional or alternative steps may be adopted.

[0066] 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" used in the specification and claims should be understood to mean "one or both" of the elements so connected, i.e., elements that exist in combination in some cases and separately in other cases. Multiple elements listed with "and / or" should be interpreted in the same manner, i.e., "one or more" of the elements so connected. In addition to the elements specifically indicated by the "and / or" clause, other elements may optionally be present, whether or not they are related to those specifically indicated. Thus, as a non-limiting example, in one embodiment, when used in conjunction with open language such as "comprising", a reference to "A and / or B" may refer 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); and so on.

[0067] As used in the specification and claims, "or" should be understood to have the same meaning as "and / or" defined above. For example, when separating listed items, "or" or "and / or" should be interpreted as inclusive, that is, including at least one, but also including more than one multiple or a series of elements, and optionally additional unlisted items. Only terms that clearly indicate the opposite, such as "only one" or "exactly one", or when used in the claims, "consisting of..." will refer to including exactly one element in a plurality or a series of elements. In general, the term "or" when preceded by an exclusive term (such as "any one", "only one" or "exactly one") should only be interpreted as indicating an exclusive choice (e.g., "one or the other, but not two"). When used in the claims, "essentially consisting of..." should have the ordinary meaning used in the field of patent law.

[0068] As briefly discussed above, as used in the specification and claims, with respect to a list of one or more elements, the phrase "at least one" should be understood to mean at least one element selected from any one or more elements in the list of elements, but does not necessarily include at least one of each element specifically listed in the list of elements, and does not exclude any combination of elements in the list of elements. This definition also allows that elements may be optionally present in addition to the elements specifically identified in the list of elements to which the phrase "at least one" refers, whether or not related 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") may refer to at least one, optionally including more than one A, without B (and optionally including elements other than B) in one embodiment; to at least one, optionally including more than one B, without A (and optionally including elements other than A) in another embodiment; to at least one, optionally including more than one B, without A (and optionally including elements other than A) in yet another embodiment; and 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.

[0069] The use of ordinal terms (such as "first," "second," "third," etc.) in the claims to modify claim elements does not, by itself, imply any priority, precedence, or order of one claim element relative to another claim element, or the temporal order in which the acts of the method are performed. Ordinal terms are used merely as labels to distinguish one claim element having a particular name from another element having the same name (but using ordinal terms) to distinguish claim elements.

[0070] Having described various aspects of the disclosure in detail, it should be apparent that modifications and variations may be made without departing from the scope of various aspects of the disclosure as defined in the appended claims. As various changes may be made to the above-described constructions, products, and methods without departing from the scope of various 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 restrictive.

[0071] It should be understood that the above description is intended to be illustrative rather than restrictive. For example, the above embodiments (and / or aspects thereof) may be used in combination with each other. In addition, without departing from its scope, many modifications may be made to adapt specific situations or materials to the teachings of various embodiments of the present disclosure. Although the size and type of materials described herein are intended to define the parameters of various embodiments of the present disclosure, these embodiments are by no means restrictive, but exemplary embodiments. By reviewing the above description, many other embodiments will be clear to those of ordinary skill in the art. Therefore, the scope of various embodiments of the present disclosure should be determined with reference to the appended claims and the full scope of the equivalents of these claims. In the appended claims, the terms "containing" and "in..." are used as the plain English equivalents of the corresponding terms "including" and "wherein". In addition, the terms "first", "second", and "third", etc. are used only as labels and are not intended to impose numerical requirements on their objects. In addition, the limitations of the following claims are not written in a means-plus-function format and are not intended to be interpreted based on 35 U.S.C. §112 (f), unless such claim limitations explicitly use the phrase "means for...", followed by a functional statement without further structure.
