[0002] Electronic atomizing devices typically include a reservoir for storing the liquid matrix. The opening of this reservoir is usually sealed with a sealant, often made of soft materials like silicone. After the liquid is injected into the reservoir, the sealant comes into contact with the liquid matrix, which can cause the following problems: silicone swells depending on the liquid matrix, leading to deformation. This swelling can affect the sealing effect and also impact the appearance. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0044] 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 indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, four, etc., unless otherwise explicitly specified.

[0045] In this utility model, unless otherwise explicitly 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 explicitly limited.

[0047] Figures 1 to 2 An electronic atomizing device 1 according to a first embodiment of the present invention is shown. The electronic atomizing device 1 includes an atomizer 100 and a power supply device 200 connected in cooperation with the atomizer 100. The power supply device 200 supplies power to the atomizer 100 and controls the opening and closing of the entire electronic atomizing device 1. The atomizer 100 contains a liquid matrix and heats and atomizes the liquid matrix to generate an aerosol after being powered on. The liquid matrix includes, but is not limited to, materials used for medical, health, and cosmetic purposes.

[0048] In some embodiments, both the atomizer 100 and the power supply 200 are generally cylindrical, and the two can be mechanically and electrically connected together along the axial direction. The power supply 200 typically includes a control circuit and a battery electrically connected to the control circuit, which can control the battery to supply power to or de-energize the atomizer 100. Of course, in other embodiments, the shape of the atomizer 100 and / or the power supply 200 is not limited; for example, it can also be other shapes such as an elliptical column, a racetrack-shaped column, a rectangular column, or a polygonal column.

[0049] In some embodiments, the atomizer 100 and the power supply 200 can be detachably connected together by a threaded connection. It is understood that in other embodiments, the atomizer 100 and the power supply 200 can also be connected together by other detachable methods such as magnetic connection or snap-fit ​​connection.

[0050] Once the liquid matrix in the atomizer 100 is depleted, the atomizer 100 can be removed from the power supply unit 200 and discarded. A new atomizer 100 can then be installed on the power supply unit 200 for continued use. In other words, the atomizer 100 can be a disposable consumable, while the power supply unit 200 can be reused. When the electrical energy in the power supply unit 200 is depleted, the battery can be charged using an external charging device.

[0051] Of course, in other embodiments, the atomizer 100 can also be reusable. When the liquid matrix in the atomizer 100 is nearly depleted or completely consumed, liquid can be added to the atomizer 100 to achieve reuse. In this way, the atomizer 100 and the power supply device 200 can be connected together in a detachable or non-detachable manner.

[0052] Combination Figures 2 to 5 As shown, the atomizer 100 may include a liquid storage assembly 20, a mouthpiece assembly 10 disposed at one end of the liquid storage assembly 20, and an atomizing assembly 40 disposed in the liquid storage assembly 20.

[0053] The liquid storage assembly 20 has a liquid storage chamber 210 and an airflow channel 220 isolated from the liquid storage chamber 210. The nozzle assembly 10 has an air intake channel 110 connected to the airflow channel 220. The liquid storage chamber 210 is used to store the liquid matrix. The atomizing assembly 40 is in fluid communication with the liquid storage chamber 210 and can atomize the liquid matrix from the liquid storage chamber 210 into an aerosol after being energized. The aerosol is then output sequentially through the airflow channel 220 and the air intake channel 110.

[0054] One end of the liquid storage chamber 210 (shown as the upper end in the figure) has an opening 211. The suction nozzle assembly 10 includes a suction nozzle 11, a first seal 12, and an isolation reinforcement 13. The first seal 12 is disposed at the opening 211 to seal the liquid storage chamber 210. The first seal 12 can be made of a soft material such as silicone, and it can be fitted with the inner wall surface of the opening 211 by interference fit to effectively seal the liquid storage chamber 210.

[0055] The suction nozzle 11 covers the liquid storage assembly 20 and the first seal 12, and the suction channel 110 extends axially through the suction nozzle 11. The suction nozzle 11 can be made of a rigid material such as plastic to ensure stable suction resistance of the suction channel 110. Of course, in other embodiments, the suction nozzle 11 can also be made of the same material as the first seal 12 (e.g., silicone), so that the suction nozzle 11 and the first seal 12 can also be a single integrally formed structural component.

[0056] The isolation reinforcement 13 is in at least partial contact with the first seal 12. The function of the isolation reinforcement 13 is to mitigate the swelling and deformation of the first seal 12 and reduce the impact of the swelling and deformation on the sealing effect of the first seal 12.

[0057] The isolation reinforcement 13 can mitigate the swelling and deformation of the first seal 12 in at least one of the following ways:

[0058] (1) The isolation reinforcement 13 is at least partially embedded in the first seal 12. In this way, the volume of the first seal 12 can be reduced, and the volume change when the first seal 12 undergoes swelling deformation is also smaller, thus having a smaller impact on the sealing effect.

[0059] (2) The isolation reinforcement 13 is at least partially disposed on the side of the first seal 12 facing the liquid storage cavity 210, so as to isolate a part of the first seal 12 from the liquid matrix in the liquid storage cavity 210, reduce the contact between the first seal 12 and the liquid matrix, and thus alleviate the swelling and deformation problem caused by the contact between the first seal 12 and the liquid matrix.

[0060] (3) The isolation reinforcement 13 is made of hard material (e.g., hard plastic). To a certain extent, the hard isolation reinforcement 13 has a certain blocking effect in the swelling direction corresponding to the first seal 12, which can slow down the swelling deformation.

[0061] The third method mentioned above is generally used in combination with the first or second method.

[0062] Specifically, in Figures 1 to 13 In the atomizer 100 shown, the isolation reinforcement 13 employs the second method described above to mitigate the swelling and deformation of the first seal 12. Specifically, the isolation reinforcement 13 is at least partially disposed on the side of the first seal 12 facing the liquid reservoir 210. By isolating the first seal 12 from the liquid matrix in the liquid reservoir 210 as much as possible through the isolation reinforcement 13, the contact between the first seal 12 and the liquid matrix is ​​reduced, thereby alleviating the swelling and deformation problem caused by the contact between the first seal 12 and the liquid matrix.

[0063] Furthermore, the first seal 12 may react with the liquid matrix upon contact, potentially releasing or precipitating substances from the silicone material. These substances could contaminate the liquid matrix, causing discoloration or deterioration, affecting both appearance and quality. The isolation reinforcement 13 effectively separates the first seal 12 from the liquid matrix in the storage chamber 210, reducing contact and mitigating the discoloration and deterioration of the liquid matrix caused by this contact.

[0064] Based on this, if the isolation reinforcement 13 is further made of a hard material, the isolation reinforcement 13 will have a certain blocking effect in the swelling direction of the first seal 12 to a certain extent, which can further slow down the swelling deformation of the first seal 12.

[0065] Of course, in other embodiments, the isolation reinforcement 13 may also be made of a soft material that does not readily react with the liquid matrix.

[0066] The design principle of the isolation reinforcement 13 is to avoid the sealing position of the first seal 12 as much as possible to avoid affecting the sealing performance of the first seal 12, while the isolation reinforcement 13 is used to isolate the non-sealing position of the first seal 12 from the liquid matrix as much as possible.

[0067] The sealing position of the first seal 12 refers to the position where the first seal 12 contacts the inner wall surface of the opening 211 of the liquid storage chamber 210 and plays a sealing role, while the non-sealing position of the first seal 12 refers to the position where the first seal 12 does not contact the inner wall surface of the opening 211.

[0068] Specifically, the first seal 12 has a non-sealing surface 1211 facing the opening 211, and the isolation reinforcement 13 is at least partially disposed on the non-sealing surface 1211 to isolate the non-sealing surface 1211 from the liquid matrix in the liquid storage chamber 210.

[0069] In some embodiments, the liquid storage chamber 210 may be annular, surrounding the periphery of the airflow channel 220. The liquid storage chamber 210 and the airflow channel 220 may be coaxially arranged, but are not limited to being coaxially arranged.

[0070] Since the opening 211 of the annular liquid storage cavity 210 is annular, the liquid storage cavity 210 has two sealing surfaces at the opening 211, namely the first sealing surface 2111 located on the outer wall surface of the opening 211 and the second sealing surface 2112 located on the inner wall surface of the opening 211.

[0071] In some embodiments, the first sealing member 12 can be sealed and fitted to both the first sealing surface 2111 and the second sealing surface 2112. That is, no isolation reinforcement member 13 is provided between the first sealing member 12 and the first sealing surface 2111 or between the first sealing member 12 and the second sealing surface 2112. In this way, the first sealing member 12 can effectively seal the liquid storage cavity 210.

[0072] Of course, in other embodiments, the first sealing member 12 may only be sealed to one of the first sealing surface 2111 and the second sealing surface 2112, while an isolation reinforcement member 13 is provided between the first sealing member 12 and the other sealing surface. In this case, in order to ensure reliable sealing of the liquid storage cavity 210, the other sealing surface can be sealed by providing another sealing member.

[0073] Specifically, in this embodiment, the liquid storage assembly 20 includes a liquid storage shell 21 and a vent pipe 22 disposed in the liquid storage shell 21. The inner wall surface of the vent pipe 22 defines an airflow channel 220, and the outer wall surface of the vent pipe 22 defines a liquid storage cavity 210 between the inner wall surface of the liquid storage shell 21 and the outer wall surface of the vent pipe 22. That is, the first sealing surface 2111 is located on the inner wall surface of the liquid storage shell 21, and the second sealing surface 2112 is located on the inner wall surface of the vent pipe 22. The upper end of the vent pipe 22 can sequentially pass through the isolation reinforcement member 13 and the first sealing member 12 and be embedded in the air intake channel 110.

[0074] In this embodiment, the liquid storage shell 21 and the vent pipe 22 are two independent structural components, which are formed separately and then assembled together. Of course, in other embodiments, the liquid storage shell 21 and the vent pipe 22 can also be integrally formed by injection molding or other methods.

[0075] The atomizing component 40 is disposed in the vent pipe 22, and the side wall of the vent pipe 22 is provided with at least one liquid inlet hole 2210 that fluidly communicates the atomizing component 40 with the liquid storage chamber 210. Preferably, there are multiple liquid inlet holes 2210, which can be evenly distributed in the circumferential direction of the vent pipe 22, which is beneficial to uniform liquid intake.

[0076] In some embodiments, the vent pipe 22 may include a first pipe segment 221 and a second pipe segment 222 arranged sequentially along the axial direction. The upper end of the second pipe segment 222 may be embedded in the air intake channel 110. The atomizing component 40 is disposed in the first pipe segment 221, and correspondingly, the liquid inlet 2210 is formed on the side wall of the first pipe segment 221.

[0077] The inner and outer diameters of the first tube segment 221 are larger than those of the second tube segment 222. The larger inner diameter of the first tube segment 221 facilitates the housing of the atomizing assembly 40. The smaller outer diameter of the second tube segment 222 increases the liquid storage space of the liquid storage chamber 210 and reduces the size of the suction channel 110 on the nozzle 11. Of course, in other embodiments, the inner and outer diameters of the first tube segment 221 and the second tube segment 222 can be equal.

[0078] Both the isolation reinforcement 13 and the first sealing member 12 can be fitted onto the second section 222 of the vent pipe 22. The first sealing member 12 has a through hole 120 formed through it, and the isolation reinforcement 13 has a through hole 130 formed through it. The upper end of the second section 222 can be sequentially fitted into the intake channel 110 through the through holes 130 and 120.

[0079] The isolation reinforcement 13 may include a first isolation portion 131, which is attached to the non-sealing surface 1211. The first isolation portion 131 is annular in shape, with a through hole 130 formed therethrough. The diameter of the through hole 130 may be larger than the outer diameter of the second pipe segment 222, so that the second pipe segment 222 can pass smoothly through the through hole 130. Of course, in other embodiments, the diameter of the through hole 130 may be equal to or slightly smaller than the outer diameter of the second pipe segment 222.

[0080] The outer wall of the second tube section 222 may have at least one protrusion 2221, and the inner wall of the nozzle 11 may have at least one locking platform 1131. When the second tube section 222 is inserted into the nozzle 11, the lower end of the protrusion 2221 can abut against the locking platform 1131 to prevent the air tube 22 from coming out of the nozzle 11 due to falling or other reasons.

[0081] In this embodiment, there is one annular protrusion 2221, and multiple locking platforms 1131 are spaced apart circumferentially on the air tube 22. The non-annular locking platforms 1131 can reduce the force required for the annular protrusion 2221 to pass through the locking platform 1131 during installation. The annular protrusion 2221 allows for alignment without the need for alignment when installing the air tube 22 and the nozzle 11.

[0082] Of course, in other embodiments, there may be multiple protrusions 2221 distributed at intervals around the circumference of the air tube 22, while there may be one locking platform 1131 in an annular shape. In other embodiments, both the locking platform 1131 and the protrusions 2221 may be annular. Of course, the protrusions 2221 and the locking platform 1131 may also be omitted, and the air tube 22 may be fixed by an interference fit between it and the nozzle 11.

[0083] The first sealing element 12 may include a sealing portion 121, which is disposed in the opening 211 and sealably engages with the inner wall surface of the opening 211. Specifically, in this embodiment, the sealing portion 121 is annular and sealably disposed between the outer wall surface of the vent pipe 22 and the inner wall surface of the liquid storage shell 21 to seal the liquid storage cavity 210. The inner wall surface of the sealing portion 121 may be interference-fitted with the outer wall surface of the vent pipe 22, and the outer wall surface of the sealing portion 121 may be sealably engaged with the inner wall surface of the liquid storage shell 21, ensuring a more reliable seal for the liquid storage cavity 210.

[0084] In some embodiments, the first sealing member 12 may further include a flange 122 extending outward from the outer wall surface of the sealing portion 121. The outer diameter of the flange 122 is larger than the inner diameter of the liquid storage shell 21. The lower end face of the suction nozzle 11 can be pressed against the upper end face of the liquid storage shell 21 through the flange 122, and the flange 122 can further improve the sealing performance of the liquid storage cavity 210. Of course, in other embodiments, the flange 122 may be omitted, and the lower end face of the suction nozzle 11 may directly abut against the upper end face of the liquid storage shell 21.

[0085] In some embodiments, the first seal 12 may further include a sleeve portion 123 extending upward from the upper end face of the sealing portion 121. The lower end face of the suction nozzle 11 extends upward and forms a mounting groove 112 for receiving the sleeve portion 123. The mounting groove 112 divides the lower portion of the suction nozzle 11 into a first portion 111 and a second portion 113 located inside the first portion 111. The inner wall surface of the second portion 113 defines a portion of the suction channel 110.

[0086] The outer diameter of the first part 111 can be approximately equal to the outer diameter of the liquid storage shell 21, which is beneficial to the overall aesthetics. Of course, in other embodiments, the outer diameter of the first part 111 can also be smaller or larger than the outer diameter of the liquid storage shell 21.

[0087] The socket 123 can be disposed in the mounting groove 112 with an interference fit, thereby fixing the first seal 12 and the suction nozzle 11. In some embodiments, the outer wall surface of the socket 123 can be formed with a plurality of protruding ribs 1231, which are evenly spaced in the circumferential direction of the socket 123. The socket 123 is interference-fitted with the inner surface of the first part 111 through the protruding ribs 1231, which makes it easier for the socket 123 to be inserted into the mounting groove 112 and can also avoid air trapping during assembly, which would affect the assembly.

[0088] Multiple through slots 1130 can be formed through the side wall of the second part 113, and the multiple through slots 1130 are distributed at intervals in the circumferential direction of the second part 113. Every two mounting bases 1131 can be separated by a through slot 1130. In addition, the through slots 1130 also make it easier to insert the socket 123 into the mounting slot 112.

[0089] Of course, in other embodiments, the sleeve 123 can be omitted, and the first sealing member 12 can be fixed to the nozzle 11 by means of adhesive bonding or other methods.

[0090] During assembly, the isolation reinforcement 13 can be assembled with the first seal 12 first, or it can be assembled with the liquid storage assembly 20 first. For example, if the isolation reinforcement 13 and / or the liquid storage shell 21 and / or the vent pipe 22 have some assembly structures formed on them, the isolation reinforcement 13 can be pre-assembled on the liquid storage assembly 20 first, and then the first seal 12 can be assembled. In addition, if the isolation reinforcement 13 is provided with a liquid injection hole, the isolation reinforcement 13 can be installed first, and then liquid can be injected; if the isolation reinforcement 13 is not provided with a liquid injection hole, liquid can be injected first, and then the isolation reinforcement 13 can be installed.

[0091] Preferably, the isolation reinforcement 13 and the first seal 12 are assembled together first, which minimizes the impact on liquid injection. For example, the isolation reinforcement 13 can be glued to the first seal 12, or the isolation reinforcement 13 and the first seal 12 can be installed with an interference fit or a snap-fit, or the isolation reinforcement 13 and the first seal 12 can be injection molded in two colors.

[0092] like Figures 4 to 6 As shown, in this embodiment, the isolation reinforcement 13 and the first sealing member 12 are interference-fitted. Specifically, at least one fixing post 132 is formed on the isolation reinforcement 13, which can protrude from the upper end surface of the first isolation portion 131. At least one fixing hole 1212 is formed on the first sealing member 12 for inserting at least one fixing post 132, which can extend upward from the lower end surface (i.e., the non-sealing surface 1211) of the sealing portion 121. It can be understood that in other embodiments, at least one fixing hole 1212 can be formed on the isolation reinforcement 13, and at least one fixing post 132 can be formed on the first sealing member 12.

[0093] The number of fixing posts 132 can be one or more. When there are multiple fixing posts 132, the multiple fixing posts 132 can be evenly spaced around the perimeter of the first isolation part 131.

[0094] At least a portion of the outer wall surface of the fixing post 132 is interference-fitted with at least a portion of the inner wall surface of the fixing hole 1212 to fix the isolation reinforcement 13 and the first seal 12 together. Preferably, a portion of the outer wall surface of the fixing post 132 is interference-fitted with a portion of the inner wall surface of the fixing hole 1212, and at least one vent groove 1320 is formed between another portion of the outer wall surface of the fixing post 132 and another portion of the inner wall surface of the fixing hole 1212. That is, the cross-sectional shape of the fixing post 132 is not the same as the cross-sectional shape of the fixing hole 1212 to avoid air entrapment during assembly and affect the assembly.

[0095] Specifically, in this embodiment, the fixing hole 1212 is a circular hole, and the fixing post 132 is a D-shaped post with a cross-sectional shape that is approximately D-shaped, thereby forming an exhaust groove 1320 between the outer wall surface of the fixing post 132 and the inner wall surface of the fixing hole 1212.

[0096] For example Figures 2 to 4 As shown, the atomizing assembly 40 includes a heating element 41, which may include a liquid-absorbing element 411 and a heating element 412. The liquid-absorbing element 411 is in fluid communication with the liquid storage chamber 210, and is able to draw liquid matrix from the liquid storage chamber 210 and transport the liquid matrix to the heating element 412. The heating element 412 atomizes the liquid matrix after being energized and heated.

[0097] The liquid-absorbing element 411 is made of a porous material, including but not limited to cotton or fibrous materials (such as natural cotton and / or synthetic cotton) or inorganic porous materials (such as ceramic materials, glass fibers, etc.).

[0098] In some embodiments, the liquid-absorbing element 411 may be cylindrical, and the heating element 412 may be disposed on the inner side of the liquid-absorbing element 411. The inner side of the liquid-absorbing element 411 defines an atomizing chamber 410, which is connected to the airflow channel 220.

[0099] In some embodiments, the liquid-absorbing element 411 may be a porous ceramic. The atomizing assembly 40 may also include a liquid-guiding element 42 sleeved on the outside of the liquid-absorbing element 411. The liquid-guiding element 42 may be a soft porous material such as cotton or fiber, which can guide the liquid matrix in the liquid storage chamber 210 to the liquid-absorbing element 411 more quickly. On the other hand, the liquid-absorbing element 411 can be pressed against the inner wall of the vent tube 22 by the liquid-guiding element 42, which is beneficial for the installation and fixation of the liquid-absorbing element 411 in the vent tube 22.

[0100] Of course, in other embodiments, the liquid guiding element 42 can be omitted, and the liquid suction element 411 can be directly pressed against the inner wall surface of the vent tube 22. In this case, the liquid suction element 411 is preferably made of soft porous materials such as cotton or fiber, but it can also be made of hard porous materials such as porous ceramics.

[0101] Understandably, in other embodiments, the heating element 41 may also adopt any known structure. For example, the liquid-absorbing element 411 is bowl-shaped, and the heating element 412 is disposed on one side of the liquid-absorbing element 411. As another example, the liquid-absorbing element 411 is rod-shaped and arranged horizontally or vertically, and the heating element 412 is disposed on the outer surface of the liquid-absorbing element 411 by means of winding or printing. Yet another example, the liquid-absorbing element 411 is a regular flat plate (e.g., cuboid) or an irregular flat plate, and at least one side of the liquid-absorbing element 411 may be provided with a groove; of course, the liquid-absorbing element 411 may also not be provided with a groove; the heating element 412 is disposed on at least one side of the liquid-absorbing element 411.

[0102] In some embodiments, the atomizer 100 further includes a base assembly 30 disposed at the other end of the liquid storage assembly 20. The base assembly 30 may include a base 31, an electrode post 32 extending longitudinally through the base 31, and an insulating member 33 disposed between the base 31 and the electrode post 32.

[0103] The base 31 may include a base 311 and a threaded portion 312 extending downward from the base 311. The outer diameter of the base 311 may be larger than the outer diameter of the threaded portion 312. The outer wall surface of the threaded portion 312 is provided with external threads for threading with the power supply device 200.

[0104] In some embodiments, the screw connection 312 may also be provided with at least one air inlet 3120 for allowing outside air to enter the atomizing chamber 410.

[0105] The lower end face of the liquid storage shell 21 can be pressed against the upper end face of the base 311 by the sealing gasket 52, which is beneficial for sealing the lower end opening of the liquid storage cavity 210. Of course, in other embodiments, the lower end face of the liquid storage shell 21 can also directly abut against the upper end face of the base 311.

[0106] The lower end of the vent pipe 22 can extend out of the liquid storage shell 21 and be embedded in the base 311. The outer wall surface of the vent pipe 22 can protrude outward to form an annular protrusion 2211. The annular protrusion 2211 can be pressed against the bottom of the liquid storage shell 21 by the sealing ring 51, which is conducive to sealing the lower opening of the liquid storage cavity 210.

[0107] In some embodiments, the base 31 can be made of metal, and the two ends of the heating element 412 can be electrically connected to the base 31 and the electrode post 32 respectively, which helps to reduce the number of electrode posts 32. Of course, in other embodiments, there can be at least two electrode posts 32. In this case, the base 31 can also be made of a non-conductive material (e.g., plastic), and the insulating member 33 can be omitted. In other embodiments, the electrode posts 32 can also be replaced by conductive sheets, conductive wires, or other electrode connectors.

[0108] Figures 7 to 9 The atomizer 100 of the second embodiment of this utility model is shown. Its main difference from the first embodiment is that in this embodiment, the first sealing member 12 only seals against the outer wall surface of the opening 211 (i.e., the inner wall surface of the liquid storage shell 21), while the inner wall surface of the opening 211 (i.e., the outer wall surface of the vent pipe 22) seals against another second sealing member 14. The first sealing member 12 and the second sealing member 14 together achieve the sealing of the liquid storage chamber 210. Furthermore, in this embodiment, the isolation reinforcement member 13 is installed with the first sealing member 12 using a snap-fit ​​connection.

[0109] Specifically, the first sealing element 12 also includes a sealing portion 121, a flange 122 extending outward from the outer wall surface of the sealing portion 121, and a sleeve portion 123 extending upward from the upper end surface of the sealing portion 121. The specific structures of the flange 122 and the sleeve portion 123 can be referred to the aforementioned related descriptions, and will not be repeated here.

[0110] The outer wall surface of the sealing part 121 can be press-fitted with the inner wall surface of the liquid storage shell 21, while the inner wall surface of the sealing part 121 and the outer wall surface of the vent pipe 22 are spaced apart.

[0111] The second sealing element 14 is made of soft materials such as silicone. The second sealing element 14 is sealed between the outer wall surface of the vent pipe 22 and the inner wall surface of the isolation reinforcement 13. Specifically, the second sealing element 14 is cylindrical and sleeved on the second pipe section 222 of the vent pipe 22. The inner wall surface of the second sealing element 14 can be interference-fitted with the outer wall surface of the second pipe section 222.

[0112] The isolation reinforcement 13 includes a first isolation portion 131 and a second isolation portion 133 extending from the inner wall surface of the first isolation portion 131 toward the first seal 12. The second isolation portion 133 may be annular, and the first seal 12 may be fitted onto the second isolation portion 133. The outer wall surface of the second seal 14 may be interference-fitted with the inner wall surface of the second isolation portion 133.

[0113] In this embodiment, the inner wall surface of the sealing part 121 is also a non-sealed position, and the second isolation part 132 can isolate this non-sealed position from the liquid matrix in the liquid storage chamber 210.

[0114] Furthermore, the second isolation portion 133 is also used to engage with the isolation reinforcement 13. Specifically, the second isolation portion 133 has an inverted L-shaped cross-section, and the inner wall surface of the sealing portion 121 forms an L-shaped locking platform 124. When the first sealing member 12 is fitted onto the second isolation portion 133, the second isolation portion 133 and the locking platform 124 engage with each other, thereby fixing the isolation reinforcement 13 and the first sealing member 12 together.

[0115] Of course, in other embodiments, the isolation reinforcement 13 and the first sealing member 12 are not limited to the specific structure described above. For example, there may be multiple second isolation portions 133, which are distributed at intervals in the circumferential direction of the first isolation portion 131. For another example, the isolation reinforcement 13 and the first sealing member 12 may be installed and fixed together by an interference fit.

[0116] When assembling the atomizer 100, the isolation reinforcement 13 is first assembled with the first seal 12 and the mouthpiece 11, the second seal 14 is pre-installed on the air tube 22, and then the two are assembled together.

[0117] Figures 10 to 11 The atomizer 100 of the third embodiment of the present invention is shown. Its main difference from the second embodiment is that, in this embodiment, the second seal 14 is sealed (e.g., with an interference fit) between the outer wall of the air duct 22 and the inner wall of the mouthpiece 11. Accordingly, during assembly, both the second seal 14 and the first seal 12 are first installed on the mouthpiece 11, and then assembled with the liquid storage assembly 20.

[0118] Specifically, the second seal 14 can be an O-ring seal or a seal of other shapes. The second seal 14 can be disposed in the suction channel 110 of the nozzle 11 and located above the mounting plate 1131. A contraction structure 1132 is formed within the suction channel 110, which can limit the upper end of the second seal 14. When the vent tube 22 is inserted into the suction channel 110, the lower end of the second seal 14 can abut against the annular protrusion 2221 of the vent tube 22. The annular protrusion 2221 and the contraction structure 1132 cooperate to hold and fix the second seal 14.

[0119] The inner wall surface of the isolation reinforcement 13 can be spaced apart from the outer wall surface of the vent pipe 22. Specifically, the inner diameter of the isolation reinforcement 13 can be greater than or equal to the outer diameter of the annular protrusion 2221, facilitating the smooth passage of the vent pipe 22 through the isolation reinforcement 13. Of course, in other embodiments, the inner diameter of the isolation reinforcement 13 can also be smaller than the outer diameter of the annular protrusion 2221, or the inner wall surface of the isolation reinforcement 13 can also contact the outer wall surface of the vent pipe 22, which helps to reduce the liquid matrix entering the second seal 14. During assembly, a certain force can be applied to make the vent pipe 22 pass through the isolation reinforcement 13.

[0120] Figures 12 to 13 The suction nozzle assembly 10 in the fourth embodiment of the present invention is shown. Its main difference from the first embodiment is that in this embodiment, the first sealing member 12 and the isolation reinforcement member 13 are formed into an integral structure by two-color injection molding or other processes, which can eliminate the need for back-end assembly and avoid problems such as poor back-end assembly.

[0121] Specifically, the first sealing element 12 also includes a sealing portion 121, a flange 122 extending outward from the outer wall surface of the sealing portion 121, and a sleeve portion 123 extending upward from the upper end surface of the sealing portion 121. The lower end surface (i.e., the non-sealing surface 1211) of the sealing portion 121 may extend upward to form an annular fixing groove 1213.

[0122] The isolation reinforcement 13 includes a first isolation portion 131 and an annular protrusion 134 extending upward from the upper end face of the first isolation portion 131. The annular protrusion 134 is inserted into the fixing groove 1213, thereby bonding the isolation reinforcement 13 and the first sealing member 12 together.

[0123] Of course, in other embodiments, an annular protrusion 134 may be formed on the first sealing member 12, and a fixing groove 1213 may be formed on the isolation reinforcement member 13.

[0124] Furthermore, an undercut (e.g., an L-shaped undercut) can be formed on the annular protrusion 134, or multiple ribs can be formed protruding from the outer wall surface of the annular protrusion 134, or any other known method can be used to improve the adhesion between the isolation reinforcement 13 and the first seal 12.

[0125] In other embodiments, a structure similar to the first embodiment may be adopted, in which one or more fixing posts are formed on one of the isolation reinforcement 13 and the first seal 12, and one or more fixing holes for inserting one or more fixing posts are formed on the other of the isolation reinforcement 13 and the first seal 12.

[0126] Figures 14 to 15 The atomizer 100 according to the fifth embodiment of the present invention is shown. In this embodiment, the isolation reinforcement 13 adopts the first method described above to mitigate the swelling and deformation of the first seal 12, that is, the isolation reinforcement 13 is at least partially embedded in the first seal 12. The isolation reinforcement 13 is preferably made of a hard material such as plastic.

[0127] Specifically, in this embodiment, the first sealing member 12 also includes a sealing portion 121, a flange 122 extending outward from the outer wall surface of the sealing portion 121, and a sleeve portion 123 extending upward from the upper end surface of the sealing portion 121. The specific structures of the flange 122 and the sleeve portion 123 can be referred to the foregoing related descriptions, and will not be repeated here.

[0128] A receiving cavity 1210 is formed on the sealing portion 121, and the isolation reinforcement 13 is at least partially disposed in the receiving cavity 1210. In this embodiment, the receiving cavity 1210 is formed by a recess in the bottom surface (i.e., the non-sealing surface 1211) of the sealing portion 121.

[0129] The receiving cavity 1210 may be annular and disposed around the through hole 120 of the first seal 12. Preferably, the receiving cavity 1210 is coaxially disposed with the sealing part 121. Of course, in other embodiments, the central axis of the receiving cavity 1210 may also be parallel to the central axis of the sealing part 121.

[0130] The isolation reinforcement 13 and the first seal 12 can be integrally molded using two-color injection molding, or the isolation reinforcement 13 can be disposed in the receiving cavity 1210 by interference fit, thereby achieving fixation between the isolation reinforcement 13 and the first seal 12. Of course, in other embodiments, the isolation reinforcement 13 and the first seal 12 can also be connected together by means of undercutting or other methods.

[0131] The isolation reinforcement 13 can be completely housed in the receiving cavity 1210, and the bottom surface of the isolation reinforcement 13 is preferably flush with the bottom surface of the sealing portion 121. Of course, in other embodiments, the bottom surface of the isolation reinforcement 13 may also be recessed into the bottom surface of the sealing portion 121.

[0132] In other embodiments, a portion of the isolation reinforcement 13 may also be located outside the receiving cavity 1210. If the portion of the isolation reinforcement 13 outside the receiving cavity 1210 extends toward and / or away from the central axis of the sealing portion 121, then the isolation reinforcement 13 can also shield at least a portion of the non-sealing surface 1211, isolating at least a portion of the non-sealing surface 1211 from the liquid medium in the liquid storage cavity 210, thereby alleviating the swelling and deformation problem caused by the first seal 12 contacting the liquid matrix.

[0133] Furthermore, in this embodiment, the suction nozzle 11 is a split structure, comprising a suction nozzle body 114 and a fixing cylinder 115 disposed within the suction nozzle body 114. The fixing cylinder 115 is mainly used to fix the air vent 22 and the first sealing member 12. Specifically, the fixing cylinder 115 is sleeved on the air vent 22, and a locking platform 1131 for engaging with the protrusion 2221 on the air vent 22 can be formed on the fixing cylinder 115. The sleeve portion 123 of the first sealing member 12 can be clamped between the outer wall surface of the fixing cylinder 115 and the inner wall surface of the suction nozzle body 114.

[0134] Other structures of the atomizer 100 can be referred to the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0135] Figures 16 to 18 The electronic atomizing device 1 in the sixth embodiment of the present invention is shown. The main difference between this embodiment and the previous embodiment is that, in this embodiment, the electronic atomizing device 1 is a disposable electronic atomizing device.

[0136] The electronic atomizing device 1 includes a housing 80 and a first seal 12, an isolation reinforcement 13, a vent tube 22, an atomizing assembly 40, a battery 60, an airflow sensor 70, and a control circuit disposed within the housing 80. The battery 60 is used to power the atomizing assembly 40.

[0137] The outer casing 80 may include a liquid storage shell 21 and a suction nozzle 11 and a base 23 respectively disposed at both ends of the liquid storage shell 21. A suction channel 110 is formed through the suction nozzle 11. The liquid storage shell 21 can be connected to the suction nozzle 11 and the base 23 in a non-removable manner, such as by snap-fit ​​connection. Of course, in other embodiments, the liquid storage shell 21 may also be integrally formed with the suction nozzle 11 and / or the base 23, or the liquid storage shell 21 may be detachably connected to the suction nozzle 11 and / or the base 23.

[0138] A vent pipe 22 is disposed in the liquid storage shell 21. The inner wall of the vent pipe 22 defines an airflow channel 220, and the outer wall of the vent pipe 22 and the inner wall of the liquid storage shell 21 define a liquid storage cavity 210. An atomizing component 40 is disposed in the vent pipe 22 and is in fluid communication with the liquid storage cavity 210.

[0139] The airflow sensor 70 is connected to the airflow channel 220. When the user inhales through the inhalation channel 110, the airflow sensor 70 can detect changes in airflow and thus control the battery 60 to power the atomizing component 40 through the control circuit.

[0140] In this embodiment, the liquid storage chamber 210 and the battery 60 are at least partially arranged side by side in the lateral direction. The liquid storage shell 21 is divided into a first cavity 21a and a second cavity 21b by a partition wall 212. The vent pipe 22, the liquid storage chamber 210, and the atomizing component 40 are located in the first cavity 21a, and the battery 60 is located in the second cavity 21b.

[0141] Furthermore, in this embodiment, the airflow channel 220 is eccentrically positioned relative to the liquid storage chamber 210. Specifically, the vent pipe 22 can be positioned close to the partition wall 212, either resting against the partition wall 212 or with a gap between it and the partition wall 212. This reduces the distance between the atomizing component 40 disposed in the vent pipe 22 and the battery 60, facilitating circuit connection.

[0142] Of course, in other embodiments, the airflow channel 220 and the liquid storage chamber 210 may also be coaxially arranged. In other embodiments, the battery 60 and the liquid storage chamber 210 may also be arranged side by side in the axial direction, with the battery 60 located below the liquid storage chamber 210.

[0143] The first sealing element 12 is at least partially disposed at the upper opening of the liquid storage chamber 210 to seal the liquid storage chamber 210. In this embodiment, the first sealing element 12 is disposed at the upper opening of the liquid storage shell 21, and simultaneously seals the upper openings of the first cavity 21a and the second cavity 21b. In other embodiments, the first sealing element 12 may only seal the upper opening of the first cavity 21a, and the upper opening of the second cavity 21b may be sealed by providing another sealing element.

[0144] The isolation reinforcement 13 is disposed on the side of the first seal 12 facing the liquid storage cavity 210, so as to isolate the first seal 12 from the liquid matrix in the liquid storage cavity 210 as much as possible, reduce the contact between the first seal 12 and the liquid matrix, and thus alleviate problems such as swelling or discoloration and deterioration of the liquid matrix caused by the contact between the first seal 12 and the liquid matrix. That is, in this embodiment, the isolation reinforcement 13 adopts the second method described above to reduce the swelling and deformation of the first seal 12.

[0145] In this embodiment, the first sealing member 12 and the isolation reinforcement member 13 are fixed together by an undercut structure. Specifically, the isolation reinforcement member 13 is sheet-shaped, with at least one hole 135 formed therethrough. The lower end face of the first sealing member 12 protrudes to form at least one snap-fit ​​125 that mates with the at least one hole 135.

[0146] In some embodiments, the latch 125 may include a rod portion 1251 disposed in the hole 135 and a head 1252 extending through the hole 135. The cross-sectional area of ​​the head 1252 is larger than the cross-sectional area of ​​the hole 135, thereby enabling the isolation reinforcement 13 to be secured to the first seal 12.

[0147] The number of snap positions 125 / hole positions 135 is not limited, and there can be one or more. In addition, the cross-sectional shape of snap positions 125 / hole positions 135 is also not limited, and it can be various shapes such as round, elliptical, square, polygonal, etc.

[0148] Of course, in other embodiments, a hole 135 may be provided on the first sealing member 12, and a buckle 125 may be provided on the isolation reinforcement member 13.

[0149] Other structures of the electronic atomizing device 1 can be referred to the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0150] Figures 19 to 20 The electronic atomizing device 1 according to the seventh embodiment of the present invention is shown. Its main difference from the sixth embodiment is that, in this embodiment, the insulating reinforcement 13 uses the aforementioned first method to mitigate the swelling and deformation of the first sealing member 12; that is, the insulating reinforcement 13 is at least partially embedded in the first sealing member 12. The insulating reinforcement 13 is preferably made of a rigid material such as plastic.

[0151] The first sealing member 12 has a receiving cavity 1210 for accommodating at least a portion of the isolation reinforcement member 13. In this embodiment, since the airflow channel 220 and the liquid storage cavity 210 are eccentrically arranged, the airflow channel 220 is located on one side of the first cavity 21a, and the isolation reinforcement member 13 can be designed as a column (e.g., cylindrical) and can be located on the other side of the first cavity 21a.

[0152] The receiving cavity 1210 can extend axially through both end faces of the first seal 12. Of course, in other embodiments, the receiving cavity 1210 can also extend upward from the lower end face of the first seal 12 but not through the upper end face of the first seal 12, or the receiving cavity 1210 can also extend downward from the upper end face of the first seal 12 but not through the lower end face of the first seal 12.

[0153] Figure 21 The electronic atomizing device 1 in the eighth embodiment of the present invention is shown. Its main difference from the seventh embodiment is that in this embodiment, the isolation reinforcement 13 is integrally formed with the mouthpiece 11, and the isolation reinforcement 13 can be formed by extending upward from the lower surface of the mouthpiece 11.

[0154] It should be noted that the structures of the first sealing member 12 and the isolation reinforcement member 13 in the disposable electronic atomizing device 1 of the sixth to eighth embodiments of this utility model can also be applied to the detachable electronic atomizing device 1 of the first to fifth embodiments described above.

[0155] The above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
