Description

Technical Field

[0001] This application relates to the field of electronic atomizing device technology, and in particular to an atomizing device and its assembly method. Background Technology

[0002] Aerosols are colloidal dispersion systems formed by the dispersion and suspension of solid or liquid particles in a gaseous medium. Since aerosols can be absorbed by the human body through the respiratory system, they provide users with a new alternative absorption method. For example, electronic nebulizers that generate aerosols from medical drugs and other aerosol-generating matrices can be used in different fields such as medicine to deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.

[0003] Currently used atomizing devices typically have a mouthpiece at one end of the housing and the other end fitted onto an atomizing base assembly. A central tube connecting the atomizing chamber and the mouthpiece is located in the center of the housing. When a user needs to inhale aerosol, the aerosol mist generated in the atomizing chamber flows along the central tube from the atomizing chamber towards the mouthpiece, thus entering the user's mouth to exert its effect.

[0004] However, current atomizer assemblies are usually composed of two or more parts, which requires assemblers to assemble multiple parts, reducing assembly efficiency and making the size requirements of each part of the atomizer assemblies relatively high, which indirectly increases the processing difficulty of the atomizer device's parts. Summary of the Invention

[0011] In one embodiment, the housing has a central tube, and a fixing hole is formed on the top of the first seal, into which the central tube is inserted; the top of the upper cover has a receiving hole and a connecting hole, the receiving hole being located below the fixing hole, the connecting hole communicating with the bottom of the connecting hole and extending horizontally toward the side of the upper cover; the side of the upper cover is recessed inward to form a connecting groove, the connecting groove communicating with the end of the connecting hole and extending downward until communicating with the atomizing chamber.

[0012] In one embodiment, the side of the second seal is recessed inward to form a connecting groove, the two ends of which extend vertically and communicate with the transition groove and the atomizing chamber, respectively.

[0013] In one embodiment, the inner wall of the first liquid inlet channel has a first opening groove extending in a vertical direction; and / or, the inner wall of the second liquid inlet channel has a second opening groove extending in a vertical direction.

[0014] In one embodiment, the atomizing device includes an air-gathering seat; the air-gathering seat is disposed in the atomizing cavity to divide the atomizing cavity into a first sub-cavity and a second sub-cavity, and an air-gathering hole is formed on the air-gathering seat to connect the first sub-cavity and the second sub-cavity.

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0038] In related technologies, atomizers typically consist of a housing, a mounting base, and an atomizing coil. The housing contains a reservoir for storing e-liquid, and the mounting base includes a separate base and a top cover. The top cover may have a first snap-fit ​​portion, and the base may have a first fixing portion that engages with the snap-fit ​​portion. Thus, the top cover and base can be mechanically coupled through the snap-fit ​​portion and the fixing portion. After the base and top cover are assembled, they form an atomizing chamber, in which the atomizing coil can be installed. The top cover may face inwards towards the housing and has an inlet channel. The atomizing coil in the atomizing chamber receives the e-liquid from the reservoir through the inlet channel, heating and atomizing the e-liquid for the user to inhale.

[0039] In addition, the base will also be designed with a second fixing part for snap-fitting with the housing; in this way, the housing, base and top cover can be assembled together through multiple snap-fitting connections.

[0040] However, this structural design requires the separate fabrication of the top cover and base, which are then snapped together. This makes the production process quite complex. Not only does it require assembly personnel to assemble multiple components, leading to low assembly efficiency and a high risk of assembly defects, but it also necessitates the design of two sets of molds for shaping the top cover and base. During the structural design phase, considering that the base needs to simultaneously engage and position with the top cover and outer shell, the dimensional accuracy requirements for the base, top cover, and outer shell are relatively higher in order to control their dimensional tolerances and ensure their snap-fit ​​fit. This further increases the processing difficulty and cost of components such as the top cover, base, and outer shell.

[0041] To effectively address the aforementioned problems, this application provides an atomizing device and its assembly method.

[0042] Please see Figures 1 to 14 As shown, the atomizing device includes: a housing 100, an atomizing seat assembly 200, a first sealing element 300, a second sealing element 700, and an atomizing core 400.

[0043] The housing 100 is used to cover the atomizing base assembly 200. A mouthpiece is formed at the end of the housing 100 away from the atomizing base assembly 200. A central tube 130 can extend from the mouthpiece into the atomizing base assembly 200 inside the housing 100, so that the user can draw the airflow mixed with atomized e-liquid through the mouthpiece.

[0044] The atomizing base assembly 200 includes an upper cover portion 210 and a base portion 220. The upper cover portion 210 and the base portion 220 are arranged opposite each other in a vertical direction, with the upper cover portion 210 located on the upper side and the base portion 220 located on the lower side. The areas on both sides of the upper cover portion 210 are integrally connected to the areas on both sides of the base portion 220. The area between the upper cover portion 210 and the base portion 220 can form an interconnected receiving cavity 240 and an atomizing cavity 230. It can be understood that the receiving cavity 240 and the atomizing cavity 230 are essentially cavities formed by the upper cover portion 210 and the base portion 220. The side of the receiving cavity 240 has an opening, and the side of the atomizing cavity 230 also has an opening. The receiving cavity 240 is located on the upper side near the upper cover portion 210, and the atomizing cavity 230 is located on the lower side near the base portion 220.

[0045] By designing the upper cover 210 and the base 220 as an integral connection, assembly personnel are spared the need to assemble the two parts, thereby improving assembly efficiency. In addition, since the upper cover 210 and the base 220 are no longer separate structures, they can be completed in one mold opening process, reducing the cost of secondary mold opening for the atomizing base assembly 200. Furthermore, since there is no longer a snap-fit ​​connection structure between the upper cover 210 and the base 220, the snap-fit ​​connection between the base 220 and the housing 100 can be controlled during structural design, reducing the dimensional accuracy requirements for the atomizing base assembly 200 and the housing 100, and ultimately reducing the processing difficulty and processing cost of the atomizing base assembly 200.

[0046] The first sealing element 300 is disposed over the upper cover portion 210. The first sealing element 300 has a first sealing groove 340. The first sealing groove 340 should be adapted to the upper cover portion 210 so that the upper cover portion 210 can be placed into the first sealing groove 340. Here, the definition of adaptation is that the shape and size of the first sealing groove 340 and the upper cover portion 210 should be equal, or slightly larger or smaller. After the first sealing element 300 is assembled with the atomizing seat assembly 200, it can cover all or at least part of the upper cover portion 210 to form the first composition.

[0047] The second sealing element 700 is covered by the atomizing core 400. The second sealing element 700 and the atomizing core 400 are placed in the receiving cavity 240 through the side opening of the receiving cavity 240. The atomizing surface 410 at the bottom of the atomizing core 400 at least partially covers the top of the atomizing cavity 230. The atomizing core 400 can receive e-liquid in the liquid storage cavity 120 (mentioned below). E-liquid dripping from the top enters the atomizing core 400. After being atomized and heated, it enters the atomizing cavity 230 from the atomizing surface 410. External airflow enters the atomizing cavity 230 and mixes with the atomized e-liquid gas to form aerosol mist. When the user inhales the atomizing device, the aerosol mist can flow to the central tube 130 through the corresponding air guiding structure, and then flow to the outside through the mouthpiece for the user to inhale.

[0048] When the housing 100 is assembled with the first composition, the upper cover 210 is inserted until it is completely inside the housing 100, and the bottom end of the housing 100 is detachably connected to the base 220; thereby, all the first seals 300, all the upper cover 210 and at least part of the base 220 are detachably inserted into the housing 100; all the receiving cavities 240 and the atomizing cavities 230 should be completely within the sealed space after the housing 100 and the first composition are covered; the housing 100 and the first seals 300 are airtight to prevent airflow from running around inside the housing 100.

[0049] Optionally, the first seal 300 can be integrally molded from a flexible and heat-resistant material such as silicone.

[0050] It is understood that in the various embodiments of this application, the following is used: Figure 1 The housing 100 shown is oriented towards the atomizer assembly 200 in the vertical direction, with the first seal 300 facing downwards towards the atomizer assembly 200 in the vertical direction and facing upwards away from the atomizer assembly 200 in the vertical direction.

[0051] In some embodiments, see Figures 1 to 4 ,as well as Figures 11 to 14 As shown, a snap-fit ​​structure 221 is formed on the periphery of the base portion 220, and a positioning structure 110 that cooperates with the snap-fit ​​structure 221 is formed on the inner wall of the housing 100; the snap-fit ​​structure 221 and the positioning structure 110 can snap together, thereby fixing the housing 100 and the base portion 220.

[0052] Specifically, the snap-fit ​​structure 221 can be an elastic card, and the positioning structure 110 can be a slot, which facilitates the insertion of the elastic card, thereby achieving relative fixation between the housing 100 and the base portion 220, and thus ensuring that the atomizing seat assembly 200 and the housing 100 are relatively fixed.

[0053] It should be noted that, in the various embodiments of this application, reference is made to... Figure 1The upper cover 210, the base 220, the receiving cavity 240 and the atomizing cavity 230 are respectively defined as the top end along the vertical direction and the bottom end along the vertical direction; the side between the top end and the bottom end is called the periphery.

[0054] In some embodiments, see Figures 1 to 4 ,as well as Figures 9 to 14 As shown, the atomizing device includes a first sealing ring 500; the first sealing ring 500 can be a rubber O-ring. An annular sealing groove 222 is formed on the periphery of the base portion 220. The sealing groove 222 is located on the lower side of the atomizing chamber 230, and the positioning structure 110 is located on the upper side of the sealing groove (222). The first sealing ring 500 is disposed in the sealing groove 222. In this way, the first sealing ring 500 achieves a seal with the housing 100 through its own deformation, preventing the airflow of the external environment from entering the interior of the housing 100 through the gap between the housing 100 and the base portion 220.

[0055] In some embodiments, see Figures 1 to 4 ,as well as Figures 9 to 14 As shown, an air inlet 223 is formed at the bottom of the base portion 220 away from the top cover portion 210, and the air inlet 223 is connected to the atomizing chamber 230.

[0056] Specifically, the air inlet 223 is usually located in the middle area of ​​the bottom of the base 220. External airflow enters the atomizing chamber 230 through the air inlet 223 and mixes with the atomized e-liquid gas to form aerosol mist. When the user inhales the atomizing device, the aerosol mist can flow to the mouthpiece through the corresponding air guiding structure and then flow to the outside for the user to inhale.

[0057] Optionally, the air inlet 223 can typically be in the shape of a half-U and inverted inside the atomizing chamber 230. The top of the air inlet 223 is typically higher than the lowest point of the atomizing chamber 230 by a certain height to prevent the e-liquid gas from flowing back out of the air inlet 223 into the external environment after condensation in the atomizing chamber 230, thus preventing leakage.

[0058] Optionally, a plurality of small air inlets 231 are formed at the bottom of the atomizing chamber 230 away from the upper cover 210, and the plurality of small air inlets 231 are connected to the air inlet 223; in this way, by setting the small air inlets 231 with a smaller area, it is ensured that the external airflow can enter the atomizing chamber 230 through the air inlet 223, and conversely, it prevents the e-liquid gas from flowing back out of the air inlet 223 into the external environment after condensation in the atomizing chamber 230, thus preventing leakage.

[0059] In some embodiments, see Figures 1 to 4 ,as well as Figures 10 to 14 As shown, the atomizing device includes a conductive terminal 600. An electrode hole 224 is formed at the bottom of the base portion 220 away from the top cover portion 210. The conductive terminal 600 passes through the electrode hole 224 and is electrically connected to the atomizing core 400.

[0060] Specifically, the atomizer core 400 includes a heating element (not shown) and an oil guide (not shown). The atomizer core 400 employs bottom heating atomization. The oil guide is used to guide the e-liquid, and the heating element generates heat through electrical current to heat the e-liquid in the oil guide into a gaseous state. This method is highly efficient, low-cost, and space-efficient, offering more flexible structural design options. The heating element can be a heating wire, heating mesh, heating plate, heating block, etc., and the material should have high thermal conductivity and high resistance. Materials with fast thermal conductivity and heat generation, such as iron-chromium-aluminum or nickel-chromium, can be used. The thickness and resistance can be adjusted according to actual application requirements, and this application does not impose any limitations. The conductive terminal 600 is disposed on the base portion 220 and passes through the electrode hole 224 until it contacts the electrode pin 430 of the atomizer core 400. This establishes an electrical connection between the conductive terminal 600 and the heating element, facilitating external power supply to the heating element.

[0061] In some embodiments, see Figures 1 to 4 As shown, the base portion 220 is integrally connected to the upper cover portion 210 on both sides of the atomizing chamber 230 via pillars 225. A liquid collection hole 226 is formed in the middle of the pillar 225, extending horizontally. Thus, after the e-liquid enters the atomizing core 400 and is heated by atomization, it enters the atomizing chamber 230 from the atomizing surface 410. When the atomized e-liquid vapor condenses in the atomizing chamber 230 due to factors such as temperature drop or blockage of the airflow channel, it can be collected in the liquid collection hole 226 along the gap between the housing 100 and the base portion 220, preventing leakage and facilitating centralized cleaning by the user.

[0062] In addition, an opening groove 227 can also be formed on the outer periphery of the column 225 away from the atomizing chamber 230; similarly, the condensed e-liquid can be collected in the opening groove 227 along the gap between the housing 100 and the base 220, avoiding leakage and making it convenient for users to clean up.

[0063] It is understandable that the opening groove 227 and the liquid collection hole 226 can be set individually or both at the same time, depending on the design.

[0064] Optionally, the sealing groove 222 should be located below the liquid collection hole 226 and the opening groove 227. In this way, the first sealing ring 500 can be set in the sealing groove 222 to achieve a circumferential seal with the housing 100, preventing the condensed e-liquid from flowing downward along the gap between the housing 100 and the base portion 220 until it flows out of the bottom of the housing 100, thereby effectively preventing leakage.

[0065] In some embodiments, see Figures 1 to 14As shown, the first seal 300 has a sealing structure 310 that seals against the inner wall of the housing 100. The sealing structure 310 may be an annular rib, in which the periphery of the first seal 300 is deformed by the annular rib, so that when the housing 100 is assembled with the first composition, the inner wall of the housing 100 is sealed to the periphery of the first seal 300, preventing airflow and air passing through the gap between the first seal 300 and the housing 100 from entering the upper region of the housing 100; it can also prevent e-liquid in the liquid storage chamber 120 of the housing 100 (mentioned below) from flowing downward through the gap between the first seal 300 and the housing 100 without entering the atomizer core 400.

[0066] In some embodiments, see Figures 3 to 14 As shown, a liquid storage chamber 120 is formed inside the housing 100, which is used to store e-liquid. A first liquid inlet channel 330 is formed on the top of the first seal 300; the first liquid inlet channel 330 generally extends vertically. A second liquid inlet channel 211 is formed on the upper cover 210, which connects the first liquid inlet channel 330 and the receiving cavity 240; an oil inlet groove 420 is formed on the top of the atomizing core 400 away from the atomizing cavity 230; the liquid storage chamber 120, the first liquid inlet channel 330, the second liquid inlet channel 211, and the oil inlet groove 420 are connected sequentially from top to bottom. In this way, the e-liquid in the liquid storage chamber 120 can pass through the first liquid inlet channel 330 and the second liquid inlet channel 211 in sequence until it enters the oil inlet groove 420 of the atomizing core 400; after the atomizing core 400 is electrically heated, the e-liquid can enter the atomizing cavity 230 from the atomizing surface 410.

[0067] Furthermore, the second seal 700 forms a third liquid inlet channel 710; the third liquid inlet channel 710 typically extends vertically. The second seal 700 covers the atomizing core 400 and is disposed within the receiving cavity 240; similarly, the second seal 700 has a second sealing groove 720, which should be adapted to the atomizing core 400, that is, the shape and size of the second sealing groove 720 and the atomizing core 400 should be equal, or slightly larger or smaller. The second seal 700, disposed within the receiving cavity 240, effectively prevents e-liquid entering the second liquid inlet channel 211 from flowing out along the edge onto the inner wall of the receiving cavity 240, thereby avoiding leakage, poor vaping, and other issues.

[0068] The liquid storage chamber 120, the first liquid inlet channel 330, the second liquid inlet channel 211, the third liquid inlet channel 710, and the oil inlet 420 are connected sequentially from top to bottom. In this way, the e-liquid in the liquid storage chamber 120 can pass sequentially through the first liquid inlet channel 330, the second liquid inlet channel 211, and the third liquid inlet channel 710 of the second seal 700, until it enters the oil inlet 420 of the atomizer core 400; after the atomizer core 400 is electrically heated, the e-liquid can enter the atomization chamber 230 from the atomizing surface 410.

[0069] Specifically, see Figure 11 and Figure 12 As shown in the figure, the single-line arrow represents the flow direction of the e-liquid. The e-liquid stored in the reservoir 120 flows sequentially through the first liquid inlet channel 330 on the first seal 300, the second liquid inlet channel 211 on the upper cover 210, the third liquid inlet channel 710 on the second seal 700, and reaches the oil inlet groove 420 at the top of the atomizing core 400. Then it flows to the lower surface of the oil guide body, that is, the atomizing surface 410. The e-liquid is heated into a gaseous state by the heating element to form e-liquid gas, which is stored in the atomizing chamber 230.

[0070] Optionally, the second seal 700 can be integrally molded from a flexible and heat-resistant material such as silicone.

[0071] In some embodiments, see Figures 3 to 14 As shown, the housing 100 has a central tube 130 inside, and the top of the first sealing member 300 has a fixing hole 350. The central tube 130 is inserted into the fixing hole 350 to facilitate suction by the user.

[0072] The top of the upper cover 210 has a receiving hole 213 and a connecting hole 214. The receiving hole 213 is located below the fixing hole 350. The connecting hole 214 communicates with the bottom of the connecting hole 214 and extends horizontally toward the side of the upper cover 210; the side of the upper cover 210 is recessed inward to form a connecting groove 215, which communicates with the end of the connecting hole 214 and extends downward until it communicates with the atomizing chamber 230. The connecting hole 214 is generally located below the receiving hole 213 and extends horizontally in the transverse direction. The bottom of the connecting hole 214 is isolated from the receiving chamber 240, and the connecting hole 214 connects the receiving hole 213 and the connecting groove 215.

[0073] Furthermore, the side of the second seal 700 can be recessed inward to form a connecting groove 730, the two ends of which extend vertically and communicate with the transition groove 215 and the atomizing chamber 230, respectively. In this way, a path channel can be formed for the aerosol mist formed by the mixed atomized e-liquid gas to flow.

[0074] Specifically, see Figures 11 to 14As shown in the diagram, the double arrows represent the direction of gas flow. External airflow enters the atomizing chamber 230 through the air inlet 223. After the airflow reaches the atomizing surface 410, it mixes with the atomized e-liquid gas to form aerosol mist. When the user inhales the atomizing device, the aerosol mist can flow from the atomizing chamber 230 through the connecting groove 730 to the transfer groove 215, and then through the transfer hole 214 and the receiving hole 213 in sequence until it reaches the fixing hole 350 and flows out. The central tube 130 is inserted into the fixing hole 350, and the aerosol mist flows out from the mouthpiece at the top of the central tube 130 and then flows to the outside for the user to inhale.

[0075] In some embodiments, see Figures 9 to 14 As shown, after the first sealing member 300 is assembled with the atomizing base assembly 200, it can cover all or at least part of the upper cover 210 to form a first composition. The first composition is placed into the receiving cavity 240 of the atomizing base assembly 200 from the side. There should be a gap 740 between the bottom of the first composition and the gas gathering base 800. Thus, the gap 740 connects the first sub-cavity 232 and the connecting groove 730. The aerosol mist formed by mixing the atomized e-liquid gas in the first sub-cavity 232 can flow from the gap 740 to the connecting groove 730, and then to the transfer groove 215. It then flows through the transfer hole 214, the receiving hole 213, and the fixing hole 350 in sequence according to the designed path until it reaches the central tube 130 and flows out for the user to inhale.

[0076] In some embodiments, see Figure 1 , Figure 5 , Figure 9 as well as Figure 11 As shown, the inner wall of the first liquid inlet channel 330 has a first opening groove 331 extending vertically. The width of the first opening groove 331 should be much smaller than the overall flow dimension of the first liquid inlet channel 330. Typically, the width of the first opening groove 331 can be 0.5-1mm; thus, by forming a capillary siphon principle through the small-sized first opening groove 331, the small area tension of the e-liquid flowing in the first liquid inlet channel 330 can be effectively broken, thereby ensuring smooth e-liquid flow in the first liquid inlet channel 330, effectively preventing e-liquid blockage in the first liquid inlet channel 330, and thus preventing the atomizer coil 400 from lacking e-liquid and causing a burnt coil, improving the user's vaping comfort.

[0077] Similarly, in some embodiments, the inner wall of the second liquid inlet channel 211 has a second opening groove 212 extending vertically. The width of the second opening groove 212 should be much smaller than the overall flow dimension of the second liquid inlet channel 211. Typically, the width of the second opening groove 212 can be 0.5-1mm; thus, by forming a capillary siphon principle through the small-sized second opening groove 212, the small area tension of the e-liquid flowing in the second liquid inlet channel 211 can be effectively broken, thereby ensuring smooth e-liquid flow in the second liquid inlet channel 211, effectively preventing e-liquid blockage in the second liquid inlet channel 211, and thus preventing the atomizer core 400 from lacking e-liquid and causing a burnt core, improving the user's vaping comfort.

[0078] It is understandable that the first opening groove 331 and the second opening groove 212 can be set individually or both can be set. In order to ensure that the e-liquid can flow smoothly in the area where the first liquid inlet channel 330 and the second liquid inlet channel 211 meet, the ends of the first opening groove 331 and the second opening groove 212 can be designed to be connected.

[0079] In some embodiments, see Figures 1 to 14 As shown, the atomizing device includes an air-gathering seat 800.

[0080] An air-gathering seat 800 is disposed in the atomizing chamber 230 to divide the atomizing chamber 230 into a first sub-chamber 232 and a second sub-chamber 233. An air-gathering hole 810 is formed on the air-gathering seat 800 to connect the first sub-chamber 232 and the second sub-chamber 233.

[0081] The area of ​​the atomizing chamber 230 other than the gas-gathering seat 800 is the first sub-chamber 232; the atomizing surface 410 at the bottom of the atomizing core 400 is located at the top of the first sub-chamber 232.

[0082] See Figure 11 and Figure 12 As shown in the figure, the single-line arrow represents the flow direction of the e-liquid. The e-liquid stored in the reservoir 120 flows sequentially through the first liquid inlet channel 330 on the first seal 300, the second liquid inlet channel 211 on the upper cover 210, the third liquid inlet channel 710 on the second seal 700, and reaches the oil inlet groove 420 at the top of the atomizing core 400. Then it flows to the lower surface of the oil guide body, that is, the atomizing surface 410. The e-liquid is heated into a gaseous state by the heating element to form e-liquid gas, which is stored in the first sub-cavity 232.

[0083] It's important to understand that originally, e-liquid is heated into a gaseous state by the heating element, forming e-liquid vapor, which is stored in a relatively large atomizing chamber 230. With a constant total amount of e-liquid vapor formed per unit time, the larger atomizing chamber 230 results in a thinner e-liquid concentration within the same volume of aerosol vapor, leading to a weaker flavor, less concentrated vapor, and a poor user experience. However, by using a concentrator 800 to divide the atomizing chamber 230 into a first sub-chamber 232 and a second sub-chamber 233, the concentrator 800 covers the area where the atomizing surface 410 is located, forming the smaller first sub-chamber 232. With the same total amount of e-liquid vapor formed per unit time, the e-liquid concentration within the first sub-chamber 232 is greater than before, thus concentrating the vapor and making the aerosol vapor fuller, improving the user's vaping comfort.

[0084] Optionally, the gas-gathering seat 800 can be integrally molded from a flexible and heat-resistant material such as silicone.

[0085] In some embodiments, see Figures 8 to 10 As shown, the gas-gathering base 800 has a spring-loaded hole 820 through which the conductive terminal 600 passes.

[0086] The conductive terminal 600 is disposed on the base portion 220, passes through the electrode hole 224 upward and through the spring pin hole 820 to reach the first sub-cavity 232. The conductive terminal 600 extends upward until it touches the electrode pin 430 at the bottom of the atomizing core 400. In this way, the conductive terminal 600 can be electrically connected to the heating element, which facilitates the external supply of power to the heating element.

[0087] In some embodiments, see Figures 8 to 14 As shown, the edge of the air-gathering seat 800 is folded upward to form a folded edge 830. The middle part of the folded edge 830 arches towards the atomizing core 400 to form a second sub-cavity 233 on the side away from the atomizing core 400. The air inlet 223 is connected to the second sub-cavity 233. The air-gathering hole 810 and the spring needle hole 820 are located in the area enclosed by the folded edge 830.

[0088] Specifically, see Figures 11 to 14As shown in the figure, the double arrows represent the direction of gas flow. The external airflow enters the second sub-cavity 233 through the air inlet 223. The e-liquid gas formed by the atomizing surface 410 is stored in the first sub-cavity 232. The first sub-cavity 232 is smaller in volume than the original atomizing cavity 230. Therefore, with the total amount of e-liquid gas formed by the atomizing surface 410 per unit time remaining unchanged, the e-liquid gas collected in the small space of the first sub-cavity 232 is more concentrated. The airflow enters the first sub-cavity 232 through the air gathering hole 810 and mixes with the atomized e-liquid gas to form aerosol mist. The e-liquid in this aerosol mist of the same volume is more concentrated, thereby gathering the smoke and making the aerosol mist more concentrated and full.

[0089] When the user inhales the atomizing device, the aerosol mist can flow sequentially from the first sub-cavity 232 through the transition groove 215, the transition hole 214, and the receiving hole 213 until it reaches the fixing hole 350 and flows out. The central tube 130 is inserted into the fixing hole 350, and the aerosol mist flows out from the nozzle at the top of the central tube 130 and then flows to the outside for the user to inhale.

[0090] Optionally, the folded edge 830 has a notch 831 to facilitate material placement and positioning during assembly.

[0091] The second aspect of this application provides an assembly method for assembling the aforementioned atomizing device, see reference. Figures 9 to 14 The apparatus shown specifically includes the following steps:

[0092] S10. The second sealing member 700 is placed over the atomizing core 400. The second sealing member 700 has a second sealing groove 720 and a third liquid inlet channel 710 communicating with the second sealing groove 720. The atomizing core 400 has an oil inlet groove 420. The second sealing groove 720 is aligned with the oil inlet groove 420 to form a first composition.

[0093] S20. The first sealing element 300 is placed on the upper cover 210 of the atomizing seat assembly 200.

[0094] S30. The gas-gathering seat 800 is placed from the side into the atomizing chamber 230 of the atomizing seat assembly 200 to divide the atomizing chamber 230 into a first sub-chamber 232 and a second sub-chamber 233.

[0095] Steps S10, S20, and S30 have no sequential relationship; any one of them can be executed first, or they can be executed simultaneously.

[0096] S40. The first composition is placed from the side into the receiving cavity 240 of the atomizing seat assembly 200. There is a gap 740 between the bottom of the first composition and the gas gathering seat 800. The gap 740 connects the first sub-cavity 232 and the connecting groove 730.

[0097] S50, Pass the conductive terminal 600 through the electrode hole 224 of the base portion 220 of the atomizer assembly 200 until it is electrically connected to the atomizer core 400.
