Technical Field

[0003] This application relates to the field of electronic atomization technology, and in particular to an atomization component and an electronic atomization device. Background Technology

[0004] Electronic atomizing devices typically include a liquid storage chamber, an oil guide body connected to the liquid storage chamber, and a heating element placed on the surface of the oil guide body. The liquid storage chamber stores liquid atomizing medium, the oil guide body adsorbs the atomizing medium and conducts it to the heating element. Under the heating action of the heating element, the atomizing medium is heated and atomized to form an aerosol for the user to inhale.

[0005] In related technologies, the liquid storage chamber is equipped with a bottom oil hole, and the oil guide body is directly placed at the bottom oil hole to absorb the atomizing medium. The surface of the oil guide body that connects to the liquid storage chamber is the liquid absorption surface, and the side of the oil guide body where the heating element is located is the atomizing surface. The atomizing surface is connected to the airflow channel to transport the atomized aerosol out through the airflow channel. Typically, in electronic atomizing devices where the liquid guide and heating element are placed vertically, the liquid absorption surface and the atomizing surface are located on two different surfaces of the oil guide body (e.g., two adjacent or opposite surfaces). Therefore, this arrangement means that there is at least a certain distance between the airflow channel and the bottom oil hole, which increases the horizontal internal space occupied, resulting in low internal space utilization of the electronic atomizing device and a smaller internal volume available for storing the atomizing medium within the same size.

[0049] In related technologies, electronic atomizing devices typically include a liquid reservoir, an oil guide, and a heating element. The liquid reservoir has a bottom outlet and stores liquid atomizing media. The oil guide is directly positioned at the bottom outlet to absorb the atomizing media, with the surface of the oil guide facing the bottom outlet serving as the liquid absorption surface. The heating element is positioned on the other surface of the oil guide (i.e., the atomizing surface). The oil guide absorbs the atomizing media, which is then heated and atomized by the heating element to form an aerosol that is released from the atomizing surface, which is connected to the airflow channel. Typically, in electronic atomizing devices where the liquid guide and heating element are placed vertically, the liquid absorption surface and the atomizing surface are located on different surfaces of the oil guide, such as adjacent or opposite surfaces. Therefore, this arrangement implies a certain distance between the airflow channel and the bottom outlet, increasing the horizontal space occupied within the electronic atomizing device and hindering its internal space utilization.

[0050] To address the aforementioned problems, this application proposes an electronic atomizing device. The following detailed description of the application is provided in conjunction with specific embodiments. It should be noted that the following description is merely illustrative and not intended to limit the scope of this application.

[0051] Example 1

[0052] Please refer to Figures 1 to 4 and Figure 7. This application provides an electronic atomizing device 100, including an oil cup 10 and an atomizing component disposed within the oil cup 10. The atomizing component includes an air passage 20, an oil guide 30, and a heating element 40. An air outlet 14 and a liquid storage chamber 11 are formed in the oil cup 10 and are isolated from each other. The air passage 20 is disposed within the oil cup 10 and has a first surface 21 and a second surface 22 disposed opposite to each other, and a lower oil hole 23 penetrating the first surface 21 and the second surface 22. The first surface 21 is disposed in the liquid storage chamber 11 (that is, the first surface 21 is the surface of the air passage 20 that is in contact with the liquid in the liquid storage chamber 11), and the lower oil hole 23 is connected to the liquid storage chamber 11. The oil guide body 30 has a third surface 31. The oil guide body 30 is connected to the air passage 20. The third surface 31 partially covers the lower oil hole 23. The third surface 31 and the second surface 22 surround and form an atomization channel 24 that is connected to the air outlet 14. The air outlet 14 and the atomization channel 24 extend longitudinally (in the z direction as shown in Figures 2 and 10). The heating element 40 is disposed on the third surface 31 of the oil guide body 30 and is located in the atomization channel 24.

[0053] With this configuration, since the heating element 40 is located on the third surface 31 of the oil guide body 30, and the lower oil hole 23 is also located on the third surface 31 of the oil guide body 30, the area for liquid absorption and the area for heating and atomization of the oil guide body 30 can be located on the same surface (third surface 31). Therefore, the flow path of the atomizing medium from the lower oil hole 23 to the heating element 40 can be shortened in the oil guide body 30. The heat generated by the heating element 40 can also be transferred to the atomizing medium near the lower oil hole 23 through the side wall of the air passage 20, which can preheat the atomizing medium and increase the flowability of the atomizing medium. The heating element 40 can fully atomize the atomizing medium at a lower temperature, improve the atomization effect, reduce dry burning problems, and reduce energy consumption. Compared to the arrangement where the lower oil hole 23 is located on the side of the oil guide body 30 away from the heating element 40 (e.g., the lower oil hole 23 and the heating element 40 are respectively located on two opposite surfaces of the oil guide body 30), the solution provided in this application does not require the addition of a structural component for setting the lower oil hole 23 on the side of the oil guide body 30 away from the heating element 40. This simplifies the structure of the electronic atomizing device 100, not only reducing the structural dimensions in the horizontal direction (y direction as shown in Figure 2), but also providing more space for the design of the dimensions of the lower oil hole 23 and the liquid storage chamber 11, thereby increasing the liquid storage capacity of the electronic atomizing device 100.

[0054] In some embodiments, the heating element 40 includes a heating part 41 and a heat-conducting part 43 connected to each other. The heating part 41 is disposed on the third surface 31 and located in the atomization channel 24. At least a portion of the heat-conducting part 43 is embedded in the lower oil hole 23.

[0055] Since the area for liquid absorption and the area for heating and atomization of the oil guide 30 can be set on the same surface (third surface 31), the flow path of the atomizing medium from the lower oil hole 23 to the heating element 40 can be shortened in the oil guide 30. The heat generated by the heating element 40 can also be transferred to the atomizing medium near the lower oil hole 23 through the side wall of the air passage 20, which can preheat the atomizing medium and increase the flowability of the atomizing medium. The heating element 40 can fully atomize the atomizing medium at a lower temperature, improve the atomization effect, reduce dry burning problems, and reduce energy consumption. Compared to the arrangement where the lower oil hole 23 is located on the side of the oil guide body 30 away from the heating element 40 (e.g., the lower oil hole 23 and the heating element 40 are respectively located on two opposite surfaces of the oil guide body 30), the solution provided in this application does not require the addition of a structural component for setting the lower oil hole 23 on the side of the oil guide body 30 away from the heating element 40. This simplifies the structure of the electronic atomizing device 100, not only reducing the structural dimensions in the horizontal direction (y direction as shown in Figure 10), but also providing more space for the design of the dimensions of the lower oil hole 23 and the liquid storage chamber 11, thereby increasing the liquid storage capacity of the electronic atomizing device 100. In addition, by embedding the heat-conducting part 43 in the lower oil hole 23, the heat-conducting part 43 increases the connection position with the air passage 20. On the one hand, it improves the connection strength between the heating element 40 and the air passage 20, preventing the heating element 40 from detaching from the air passage 20. On the other hand, by utilizing the supporting effect of the heat-conducting part 43 on the heating element 41, it can prevent the heating element 41 from deforming, and avoid the problem of dry burning due to poor contact between the heating element 40 and the oil guide 30.

[0056] Optionally, the heating element 41 is the part of the heating element 40 through which current can flow, and the heat-conducting element 43 is the part of the heating element 40 through which no current flows. Specifically, one end of the heat-conducting element 43 is connected to the heating element 41, and the other end is a free end. Therefore, no current loop is formed in the heat-conducting element 43, thus avoiding active heating of the atomizing medium in the lower oil hole 23 by the heat-conducting element 43, preventing overheating of the atomizing medium in the lower oil hole, and thus avoiding the problem of excessive boiling or increased fluidity of the atomizing medium, which can easily lead to leakage. At the same time, although the heat-conducting element 43 does not actively heat, because the heat-conducting element 43 is connected to the heating element 41, it can transfer a portion of the heat from the heating element 41 to the lower oil hole 23, thereby preheating the atomizing medium to improve its fluidity. In this way, the preheating of the atomizing medium in the lower oil hole 23 can be kept at a suitable temperature, which can prevent the atomizing medium from deteriorating due to excessive temperature and ensure that the atomizing medium has suitable fluidity.

[0057] In some embodiments, the air passage 20 has a drain hole 23 on each side of the atomizing channel 24. The heating element has a heat-conducting portion 43 corresponding to each of the two drain holes 23. The heat-conducting portions 43 are located on both sides of the heating element 41, and at least a portion of the heat-conducting portion 43 is bent to extend into the drain hole 23. By providing heat-conducting portions 43 on both sides of the heating element 41, the fixing and supporting effect of the heat-conducting portions 43 on the heating element 41 can be improved, resulting in more even force distribution on both sides of the heating element 41 and further improving the effect of preventing deformation of the heating element 41. The heat-conducting portions 43 are bent, so that the heat-conducting portions 43 on both sides can clamp and fix the air passage 20 through the drain holes 23, improving the connection strength between the heating element 40 and the air passage 20.

[0058] Optionally, the heating element 41 can be configured as one or two. When a heating element 41 is configured, heat-conducting elements 43 can be configured on both sides of the heating element 41, and the heat-conducting elements 43 on both sides can be configured symmetrically. When two heating elements 41 are configured, the two heating elements 41 can be connected in series, and a heat-conducting element 43 is configured on one side of each heating element 41 adjacent to the lower oil hole 23 (as shown in Figures 10 and 11).

[0059] In some embodiments, the lower oil hole 23 is configured as an oblong hole, with the long side of the oblong hole extending in the same direction as the atomizing channel 24. The heating element 40 is provided with a plurality of heat-conducting parts 43, which are spaced apart along the long side of the oblong hole (in the z direction as shown in FIG. 10). The heat-conducting parts 43 are in contact with the inner wall surface of the lower oil hole 23. On the one hand, by providing a plurality of heat-conducting parts 43 along the long side of the lower oil hole 23, the contact area between the heat-conducting parts 43 and the lower oil hole 23 can be further increased, thereby improving the connection strength between the heating element 40 and the air passage component 20. By extending the lower oil hole 23 along the extension direction of the atomizing channel 24, the oil discharge efficiency of the lower oil hole 23 can be improved.

[0060] In some embodiments, the air passage 20 includes a curved portion 26 and a flat portion 25 continuously disposed. The flat portion 25 is connected to a third surface 31, and the curved portion 26 and the third surface 31 are spaced apart to form an atomization channel 24. The heating element 40 is disposed corresponding to the curved portion 26. The lower oil hole 23 can be disposed in the flat portion 25 or at the connection between the flat portion 25 and the curved portion 26. By continuously disposing of the flat portion 25 and the curved portion 26, when the flat portion 25 is attached to the third surface 31 of the oil guide 30, the curved portion 26 can be spaced apart from the third surface 31, and the third surface 31 and the curved portion 26 together form the atomization channel 24. The heating element 40 is disposed corresponding to the curved portion 26, so that the heating element 40 can be exposed in the atomization channel 24. The atomizing medium is heated and atomized by the heating element 40 to form an aerosol and released into the atomization channel 24. By connecting the flat portion 25 of the air passage 20 to the oil guide 30, the contact area between the air passage 20 and the oil guide 30 can be increased, thereby improving the connection strength between them. The third surface 31 of the oil guide 30 can fit against the second surface 22 of the flat portion 25 and cover the lower oil hole 23. This helps the atomizing medium to flow through the lower oil hole 23 and reach the third surface 31 of the oil guide 30, ensuring that the atomizing medium can be absorbed by the oil guide 30.

[0061] For example, the third surface 31 of the oil guide 30 is set as a plane, which facilitates installation and mating with the flat portion 25 of the air passage 20.

[0062] Of course, as an alternative implementation, the oil guide 30 can be configured as a curved surface, with the curved portion of the oil guide 30 enclosing the air passage 20 to form an atomization channel 24. Alternatively, the air passage 20 can be configured as a flat surface, while the oil guide 30 is configured as a curved surface, so that the air passage 20 and the oil guide 30 enclose the atomization channel 24. This is not a limitation.

[0063] In some embodiments, the air passage component 20 includes two planar portions 25, which are respectively connected to both sides of the curved portion 26. A second surface 22 of each planar portion 25 is further provided with a fixing arm 252, which extends in a direction away from the first surface 21 (the negative direction of the y-axis as shown in FIG. 10). An oil guide body 30 is disposed between the two fixing arms 252. By disposing the oil guide body 30 between the two fixing arms 252, the connection strength between the air passage component 20 and the oil guide body 30 can be further enhanced, preventing the oil guide body 30 from detaching from the air passage component 20 and improving the installation reliability between the air passage component 20 and the oil guide body 30.

[0064] In some embodiments, the wall thickness of the curved portion 26 is greater than the wall thickness of the flat portion 25. This thinner flat portion 25 helps to reduce the opening depth of the lower oil hole 23, facilitating the smooth flow of the atomizing medium to the third surface 31 of the oil guide 30. Furthermore, it improves heat conduction, allowing the heating effect of the heating element 40 to be conducted through the flat portion 25 to the atomizing medium surrounding the lower oil hole 23, thus preheating the atomizing medium. The larger wall thickness of the curved portion 26 helps to improve the structural strength of the atomizing channel 24, preventing deformation of the atomizing channel 24.

[0065] In some embodiments, the heating element 40 includes a heating section 41, which is offset from the lower oil hole 23 along the width direction of the oil guide body 30 (the x-direction as shown in Figures 2 and 10). This creates a certain distance between the heating section 41 and the lower oil hole 23, allowing the atomizing medium to flow a certain distance along the width direction of the oil guide body 30 before reaching the heating section 41. This helps prevent the heating section 41 from being directly immersed in the atomizing medium, thus avoiding excessive atomizing medium and insufficient atomization.

[0066] In some embodiments, there is a minimum distance D between the heating element 41 and the edge of the lower oil hole 23, wherein the minimum distance D satisfies 0.1mm ≤ D ≤ 6mm, for example, D can be 0.1mm, 0.3mm, 0.5mm, 0.8mm, 1mm, 1.5mm, 2mm, 4mm, 6mm, etc. Controlling the minimum distance D within the above range ensures, on the one hand, that there is sufficient distance between the heating element 41 and the lower oil hole 23 to prevent the heating element 41 from being directly immersed in the atomizing medium; on the other hand, it ensures that the heat generated by the heating element 41 can be transferred to the edge of the lower oil hole 23, thereby preheating the atomizing medium.

[0067] For example, the minimum distance D satisfies 0.5mm ≤ D ≤ 2mm. For example, D can be 0.5mm, 0.6mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.9mm, 2mm, etc. Controlling the minimum distance D within the above range can both prevent the heating element 41 from being too small, causing it to be excessively immersed in the atomizing medium, and ensure that the heat generated by the heating element 41 can be transferred to the edge of the lower oil hole 23.

[0068] In some embodiments, the heating element 40 includes a heating portion 41 and an electrode portion 42 connected to each other. The heating portion 41 is disposed corresponding to the curved portion 26 and exposed in the atomization channel 24. A limiting post 251 is protruding from the second surface 22 of the planar portion 25. The electrode portion 42 is provided with a first mounting structure 421, which cooperates with the limiting post 251 to connect the heating element 40 to the air passage component 20. The heating element 40 is held by the oil guide body 30 and the planar portion 25 of the air passage component 20, which helps to stably install the heating element 40 between the oil guide body 30 and the air passage component 20. Through the cooperation between the first mounting structure 421 of the electrode portion 42 and the limiting post 251 of the planar portion 25, the stability of the installation of the heating element 40 can be further improved, effectively preventing the heating element 40 from falling off the oil guide body 30 and the air passage component 20. The cooperation between the first mounting structure 421 and the planar portion 25 can also play a positioning role in the installation of the heating element 40, improving the installation accuracy of the heating element 40. For example, the first mounting structure 421 may be a mounting hole, a limiting slot, or other structures.

[0069] In some embodiments, the oil guide body 30 is also provided with a second mounting structure 33 corresponding to the limiting post 251. When the oil guide body 30 is installed with the air passage component 20, the limiting post 251 can pass into the second mounting structure 33 to achieve the connection between the oil guide body 30 and the air passage component 20. Specifically, the limiting post 251 passes through the first mounting structure 421 and the second mounting structure 33 in sequence, which can assemble the oil guide body 30, the heating element 40 and the air passage component 20 together, improving the stability and reliability of the connection. Exemplarily, the second mounting structure 33 can be a mounting hole, a limiting slot, or other structures.

[0070] In some embodiments, the electrode portion 42 is at least disposed at the top or bottom of the heating element 41. The electrode portion 42 extends along the width direction of the air passage 20 (the x-direction shown in FIG. 10) to the planar portion 25, and the oil guide member and the planar portion 25 clamp the electrode portion 42. By providing the electrode portion 42 to extend to the planar portion 25, the second surface 22 of the planar portion 25 and the third surface 31 of the oil guide member can jointly clamp the electrode portion 42. The planar portion 25 and the third surface 31 are set as planes, which can improve the clamping force on the electrode portion 42, prevent the heating element 40 from falling off between the oil guide member and the air passage 20, and improve the installation stability of the heating element 40. By clamping the electrode portion 42, the normal operation of the heating element 41 can be unaffected, and the reliability of the heating element 40 can be improved. Exemplarily, the electrode portion 42 can be disposed at either the top or the bottom of the heating element 41, or it can be disposed at both the top and the bottom of the heating element 41, which is not limited here.

[0071] In some embodiments, referring to FIG12, the electrode portion 42 is further provided with a bending portion 422, which extends along the second surface 22 to the bottom of the flat portion 25. The electronic atomizing device 100 also includes a base 60 and an electrode 61. The base 60 is connected to the bottom of the air passage component 20, and the electrode 61 is disposed in the base 60, with one end of the electrode 61 abutting against the bending portion 422. The bending portion 422 increases the contact area between the heating element 40 and the air passage component 20, enhancing the connection strength between them. Furthermore, when the base 60 and the air passage component 20 are assembled, one end of the electrode 61 can abut against the bottom of the air passage component 20. By extending the bending portion 422 to the bottom of the air passage component 20, an electrical connection can be established between the bending portion 422 and the electrode 61, enabling the electrode 61 to supply power to the heating element 40. The bend 422 can also increase the contact area between the electrode 42 and the electrode 61, avoiding the problem of poor contact between the heating element 40 and the electrode 61, and improving the reliability of the electrical connection. Optionally, both the air passage component 20 and the base 60 can be provided with a snap-fit ​​structure 62 (such as a snap-fit ​​hole and a snap-fit ​​hook or a snap-fit ​​protrusion) to facilitate the snap-fit ​​connection between the air passage component 20 and the base 60.

[0072] In order to balance the air pressure in the liquid storage chamber 11 so that the atomizing medium can flow out continuously and automatically, in some embodiments, the air passage 20 is provided with a return air structure 27, which is used to connect the liquid storage chamber 11 to the outside atmosphere.

[0073] In some embodiments, the air return structure 27 includes an air return port 271 and an air return groove 272. The air return port 271 is disposed through the first surface 21 and the second surface 22, and is connected to the liquid storage chamber 11. The air return port 271 is spaced apart from the lower oil hole 23. A portion of the air return groove 272 is disposed at the junction of the first surface 21 and the second surface 22. One end of the air return groove 272 is connected to the side of the air return port 271 facing the oil guide body 30, and the other end of the air return groove 272 is connected to the atomization channel 24 or used to connect to the outside atmosphere. By providing the air return structure 27, air from the outside atmosphere can be allowed to enter the liquid storage chamber 11, so that after a portion of the atomizing medium flows out, the liquid storage chamber 11 can achieve a balance of internal and external air pressure by replenishing air, ensuring that the atomizing medium can flow out smoothly and continuously from the lower oil hole 23, and ensuring the smooth flow of oil from the lower oil hole 23. By providing a return air groove 272 at the connection between the first surface 21 and the second surface 22 of the air passage component 20, the return air groove 272 can communicate with the return air port 271, ensuring that the return air groove 272 can provide air to the return air port 271. On the other hand, it can save the space occupied by the return air groove 272 in the air passage component 20, making the return air structure 27 more compact. The return air port 271 and the lower oil hole 23 are spaced apart, which can prevent air bubbles generated by the return air port 271 from blocking the lower oil hole 23 and improve the smooth flow of oil from the lower oil hole 23.

[0074] Optionally, the return air port 271 is positioned above the lower oil hole 23 along the direction of gravity (the z-direction as shown in Figure 2). In this way, the bubbles generated by the return air port 271 can rise in the atomizing medium without passing through the lower oil hole 23, further reducing the risk of the lower oil hole 23 being blocked by bubbles and ensuring the smoothness and reliability of oil flow from the lower oil hole 23.

[0075] In some embodiments, the second surface 22 of the air passage 20 is provided with a boss 221, and the return air port 271 is disposed in the boss 221. The height of the boss 221 protruding from the second surface 22 is greater than or equal to the thickness of the heating element 40. In this way, when the oil guide 30 and the air passage 20 are mated, the third surface 31 of the oil guide 30 can fit with the second surface 22 of the air passage 20, especially with the surface of the boss 221, ensuring that the oil guide 30 and the return air port 271 fit together at the opening of the second surface 22. This avoids the formation of a gap between the third surface 31 and the return air port 271 due to the thickness of the heating element 40 itself, and prevents the atomizing medium from seeping out from the gap.

[0076] As an alternative implementation, in addition to the above-described configuration, the return gas structure 27 can also have a through groove (not shown) provided on the gas passage 20 along the thickness direction of the gas passage (y direction as shown in Figures 2 and 10). One end of the through groove extends to the first surface 21 of the gas passage 20, and the other end extends to the second surface 22 of the gas passage 20. One end of the second surface 22 of the through groove is covered by the oil guide body 30. In this way, the through groove can also connect the liquid storage chamber to the outside atmosphere.

[0077] In some embodiments, referring to Figures 5 to 7, the electronic atomizing device 100 further includes a sealing element 50. The sealing element 50 is disposed inside the oil cup 10 and is sleeved outside the oil guide body 30 and the air passage component 20. The sealing element 50 has an air vent 51 and an oil drain window 52. The air vent 51 connects to the air passage 14 and the atomization channel 24, and the oil drain window 52 connects to the liquid storage chamber 11. By providing the sealing element 50, the air passage component 20, the heating element 40, and the oil guide body 30 can be further fixed. By using the sealing element 50 to sleeve outside the oil guide body 30 and the air passage component 20, the connection strength between the oil guide body 30 and the air passage component 20 can be improved, thereby better holding the heating element 40 between the air passage component 20 and the oil guide body 30. On the other hand, the seal 50 is assembled with the oil cup 10 to seal the liquid storage chamber 11. The lower oil window 52 of the seal 50 allows the atomizing medium to pass through, ensuring that the atomizing medium can flow to the lower oil hole 23, while the rest of the seal 50 does not allow the atomizing medium to pass through, thus sealing the liquid storage chamber 11.

[0078] In some embodiments, a fourth surface 32 is provided along the thickness direction of the oil guide body 30 (the y-direction shown in Figures 2 and 11), opposite to the third surface 31. A liquid-locking groove 53 is provided on the inner surface of the sealing member 50 facing the fourth surface 32, and the fourth surface 32 covers the opening of the liquid-locking groove 53. By providing the liquid-locking groove 53, leakage of the atomizing medium adsorbed in the oil guide body 30 from the fourth surface 32 can be prevented. By connecting the fourth surface 32 with the liquid-locking groove 53, the liquid-locking groove 53 can block and seal the atomizing medium that permeates from the fourth surface 32 of the oil guide body 30, preventing leakage under gravity. Thus, while preventing leakage of the atomizing medium from the fourth surface 32, it can also be sealed in the liquid-locking groove 53, thereby ensuring that the electronic atomizing device 100 has good sealing performance.

[0079] For example, a portion of the oil guide 30 may cover the opening of the liquid-locking groove 53, while another portion of the oil guide 30 may be located outside the opening of the liquid-locking groove 53. Alternatively, a portion of the oil guide 30 may be embedded in the liquid-locking groove 53, with the remainder located outside the opening of the liquid-locking groove 53. Or, the entire oil guide 30 may be embedded in the liquid-locking groove 53, covering the opening of the liquid-locking groove 53; the specific configuration is not limited.

[0080] In some embodiments, at least one protruding structure 531 is provided in the liquid-locking groove 53. The projection of the protruding structure 531 along the thickness direction of the oil guide 30 is located in the heating element 40. The protruding structure 531 abuts against the fourth surface 32 and compresses the oil guide 30 along the thickness direction (y direction as shown in FIG. 4). That is, after the sealing member 50 is assembled with the oil guide 30 and the air passage member 20, the protruding structure 531 can squeeze the oil guide 30 towards the heating element 40, and the oil guide 30 is in a compressed state. By utilizing the squeezing action of the protruding structure 531, the oil guide 30 can be lifted and squeezed towards one side of the heating element 40, thereby improving the tightness of the fit between the heating element 40 and the oil guide 30, avoiding the problem of dry burning of the heating element 40 caused by poor contact between the heating element 40 and the oil guide 30, and improving the reliability of the heating element 40 and the oil guide 30.

[0081] Optionally, the raised structure 531 can be a block-shaped structure such as a hemispherical, conical, frustum, or pyramidal shape, or it can be an extended strip-shaped structure; no limitation is made here. When multiple raised structures 531 are provided in the liquid-locking groove 53, the multiple raised structures 531 can be arranged at intervals, for example, they can be arranged in an array. The cross-sectional area of ​​the raised structure 531 can be set to gradually decrease along the direction away from the bottom of the liquid-locking groove 53, which helps to facilitate the demolding of the raised structure 531 when the seal 50 is formed.

[0082] In some embodiments, the electronic atomizing device 100 further includes a base 60 connected to the bottom of the air passage component 20. An electrode 61 may be disposed in the base 60, passing through the base 60 and contacting the heating element to supply power to the heating element. Both the air passage component 20 and the base 60 may be provided with a snap-fit ​​structure 62 (e.g., a snap-fit ​​hole and a snap-fit ​​hook or a snap-fit ​​protrusion) to facilitate the snap-fit ​​connection between the air passage component 20 and the base 60.

[0083] In some embodiments, referring to FIG7, the oil cup 10 includes a housing 12 and a vent pipe 13. The internal space of the vent pipe 13 forms an air outlet 14. The housing 12 and the vent pipe 13 are spaced apart, and the liquid storage chamber 11 is formed in the space between the housing 12 and the vent pipe 13. One end of the vent pipe 13 is connected to the housing 12 to form a suction nozzle. When the oil cup 10 is connected to the sealing member 50, the other end of the vent pipe 13 is sealed to the vent port 51 of the sealing member 50. The atomization channel 24, the vent port 51, and the air outlet 14 are sequentially interconnected. After the atomizing medium is heated and atomized, it forms an aerosol and is released into the atomization channel 24. The aerosol enters the vent pipe 13 through the vent port 51 and finally reaches the suction nozzle for suction.

[0084] For example, referring to Figures 8 and 13, during the assembly of the electronic atomizing device 100, the heating element 40 and the oil guide 30 can be sequentially installed into the air passage component 20. The oil guide 30 and the air passage component 20 together hold the heating element 40, and the heating element 40, the oil guide 30, and the air passage component 20 are assembled to form a first assembly structure 101. Then, the sealing element 50 is fitted onto the outer periphery of the first assembly structure 101 to form a second assembly structure 102. At the same time, electrodes 61, magnets, and other structures can be installed in the base 60. Next, the second assembly structure 102 is assembled with the base 60. Specifically, the bottom of the air passage component 20 is connected to the base 60, and the side clips of the air passage component 20 are engaged with the clips on the base 60, thereby installing the second assembly structure 102 with the base 60 to form a third assembly structure 103. Finally, the atomizing medium is injected into the oil cup 10, and the third assembly structure 103 is inserted into the opening of the oil cup 10. The sealing element 50 is sealed to the inner wall of the oil cup 10 to prevent the atomizing medium from leaking from the opening of the oil cup 10. Using this configuration, the electronic atomizing device 100 can be assembled in several steps, simplifying the assembly process and improving the assembly efficiency.

[0085] Example 2

[0086] Referring to Figures 7 and 9, this application provides an electronic atomizing device, which includes an oil cup and an atomizing component. The atomizing component cooperates with the oil cup 10 and surrounds a liquid storage chamber 11. The oil cup 10 has an air outlet 14 that is isolated from the liquid storage chamber 11. The atomizing component includes a sealing element 50, an air passage component 20, an oil guide body 30, and a heating element 40. The sealing element 50 has an air vent 51 and an oil outlet window 52. The air passage component 20 is disposed within the sealing element 50 and has a first surface 21 and a second surface 22 disposed opposite to each other, and an oil outlet 23 penetrating the first surface 21 and the second surface 22. The oil outlet 23 communicates with the oil outlet window 52 and is connected to the liquid storage chamber 11 through the oil outlet window 52. The first surface 21 is the surface that contacts the liquid in the liquid storage chamber 11. An oil guide body 30 is disposed within the sealing member 50 and on the second surface 22 of the air passage member 20. The oil guide body 30 has a third surface 31, which partially covers the lower oil hole 23. The third surface 31 and the second surface 22 together form an atomizing channel 24 extending longitudinally (in the z direction as shown in Figure 9). The atomizing channel 24 is connected to the air outlet 14 through the air vent 51. A heating element 40 is disposed on the third surface 31 of the oil guide body 30 and is located in the atomizing channel 24.

[0087] The atomizing assembly achieves a sealed connection with the oil cup 10 through the sealing element 50, and also seals the liquid storage chamber 11. The lower oil window 52 of the sealing element 50 allows the atomizing medium to pass through. The sealing element 50 also fixes the air passage 20, the heating element 40, and the oil guide 30. The areas for liquid absorption and heating atomization of the oil guide 30 are both located on the third surface 31, thus shortening the flow path of the atomizing medium from the lower oil hole 23 to the heating element 40. The heat generated by the heating element 40 can also be transferred to the atomizing medium near the lower oil hole 23 through the side wall of the air passage 20, preheating the atomizing medium and increasing its flowability. The heating element 40 can fully atomize the atomizing medium at a lower temperature, improving the atomization effect, reducing dry burning, and lowering energy consumption. The atomizing assembly provided in this application does not require the addition of a structural component for setting a lower oil hole 23 on the side of the oil guide body 30 away from the heating element 40, thereby making the atomizing assembly more structurally simpler. It can not only reduce the structural dimensions in the horizontal direction (y direction as shown in Figure 9), but also provide more space for the size design of the lower oil hole 23 and the liquid storage chamber 11, thereby increasing the liquid storage capacity of the liquid storage chamber 11.

[0088] Optionally, the oil cup 10 in this embodiment can adopt the same structure as in Embodiment 1, or in other alternative embodiments, the oil cup 10 can adopt a different structure than in Embodiment 1, which is not limited here. Optionally, except for the arrangement of the atomizing component, the other structures not described in detail in Embodiment 2 can be the same as those in Embodiment 1, which will not be repeated here.

[0089] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
