In the specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0041] The electronic atomization device in the related art is usually provided with an oil guide body at the lower oil hole of the liquid storage cavity, and a heating body is arranged at the side of the oil guide body away from the lower oil hole. When the atomization surface (the surface where the heating body is arranged) of the oil guide body is placed parallel or inclined to the airflow channel, this arrangement will cause a certain spacing distance between the atomization surface and the airflow channel, thereby increasing the space occupation in the horizontal direction, which is not conducive to improving the internal space utilization rate of the electronic atomization device. Therefore, the improvement scheme in the related art is to arrange the heating body between the oil guide body and the air duct piece, and to arrange the atomization surface and the liquid suction surface of the oil guide body on the same surface.

[0042] In order to solve the above technical problems, the present application provides an electronic atomization device, the content of the present application will be described in detail below in combination with specific embodiments. It should be noted that the following description is only exemplary and not a specific limitation of the present application.

[0043] Please refer to Figures 1 to 4 and Figure 7This application provides an electronic atomizing device 100, including an oil cup 10 and an atomizing component disposed within the oil cup. The atomizing component includes an air passage 20, an oil guide 30, and a heating element 40. The oil cup 10 has an air outlet 14 and a liquid storage chamber 11 that 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, and the lower oil hole 23 communicates with the liquid storage chamber 11. The oil guide 30 has a third surface 31 and is connected to the air passage 20. A portion of the third surface 31 and the second surface 22 enclose an atomizing channel 24 communicating with the air outlet 14. The atomizing channel 24 and the air outlet 14 extend longitudinally (e.g., ...). Figure 2 (shown in the z direction), a portion of the third surface 31 covers the lower oil hole 23. 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 is located in the atomization channel 24. At least a portion of the heat-conducting part 43 is embedded in the lower oil hole 23.

[0044] Since the liquid absorption area and the heating and atomization area of ​​the oil guide 30 can be disposed 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, 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 reducing energy consumption. Compared with the arrangement of placing the lower oil hole 23 on the side of the oil guide 30 away from the heating element 40 (e.g., the lower oil hole 23 and the heating element 40 are respectively disposed on two opposite surfaces of the oil guide 30), the solution provided in this application does not require the addition of a structural component for the lower oil hole 23 on the side of the oil guide 30 away from the heating element 40, thus making the electronic atomizing device 100 more structurally simpler. This not only reduces the horizontal (e.g.) Figure 2 The structural dimensions (shown in the y-direction) allow for greater space in the design of the lower oil hole 23 and the liquid storage chamber 11, increasing the liquid storage capacity of the electronic atomizing device 100. Furthermore, by embedding the heat-conducting part 43 in the lower oil hole 23, the heat-conducting part 43 increases the connection point with the air passage component 20. This improves the connection strength between the heating element 40 and the air passage component 20, preventing the heating element 40 from detaching from the air passage component 20. Additionally, the supporting effect of the heat-conducting part 43 on the heating element 41 prevents deformation of the heating element 41, avoiding poor contact between the heating element 40 and the oil guide 30, which could lead to dry burning.

[0045] Optionally, the heating portion 41 is a portion of the heating body 40 through which current can flow, and the heat-conducting portion 43 is a portion of the heating body 40 through which no current flows. Specifically, one end of the heat-conducting portion 43 is connected to the heating portion 41, and the other end is a free end. Therefore, no current loop is formed in the heat-conducting portion 43, and thus the heat-conducting portion 43 can avoid actively heating the atomized medium in the oil outlet hole 23, and can avoid overheating of the atomized medium in the oil outlet hole, thereby avoiding problems such as excessive boiling or increased flowability of the atomized medium, which can cause liquid leakage. At the same time, although the heat-conducting portion 43 does not actively heat, since the heat-conducting portion 43 is connected to the heating portion 41, a portion of the heat of the heating portion 41 can be transferred to the oil outlet hole 23, thereby preheating the atomized medium to improve the flowability of the atomized medium. In this way, the atomized medium in the oil outlet hole 23 can be preheated to an appropriate temperature, which can avoid deterioration of the atomized medium due to excessively high temperature, and can also allow the atomized medium to have appropriate flowability.

[0046] In some embodiments, the airway piece 20 is provided with one oil outlet hole 23 on each side of the atomization channel 24, and the heating body is provided with a heat-conducting portion 43 corresponding to each of the two oil outlet holes 23. The heat-conducting portion 43 is arranged on both sides of the heating portion 41, and at least a portion of the heat-conducting portion 43 is bent to extend into the oil outlet hole 23. By arranging the heat-conducting portion 43 on both sides of the heating portion 41, the fixing and supporting effects of the heat-conducting portion 43 on the heating portion 41 can be improved, the stress on both sides of the heating portion 41 can be more uniform, and the effect of preventing deformation of the heating portion 41 can be further improved. The heat-conducting portion 43 is arranged in a bent manner, so that the heat-conducting portions 43 on both sides can clamp and fix the airway piece 20 through the oil outlet hole 23, thereby improving the connection strength between the heating body 40 and the airway piece 20.

[0047] Optionally, the heating portion 41 can be provided as one or two. When one heating portion 41 is provided, heat-conducting portions 43 can be arranged on both sides of the heating portion 41, and the heat-conducting portions 43 on both sides can be arranged symmetrically. When two heating portions 41 are provided, the two heating portions 41 can be connected in series with each other, and a heat-conducting portion 43 is arranged on one side of each heating portion 41 adjacent to the oil outlet hole 23 (as shown in Figure 2 、 Figure 3 ).

[0048] In some embodiments, the oil outlet hole 23 is provided as a waist-shaped hole, the long side of the waist-shaped hole extends in the same direction as the atomization channel 24, and the heating body 40 is provided with a plurality of heat-conducting portions 43. The plurality of heat-conducting portions 43 are arranged at intervals along the long side direction of the waist-shaped hole (as shown in Figure 2(As shown in the z-direction), the heat-conducting part 43 is attached to the inner wall surface of the lower oil hole 23. On the one hand, by providing multiple heat-conducting parts 43 along the long side extension direction of the lower oil hole 23, the contact area between the heat-conducting part 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 atomization channel 24, the oil discharge efficiency of the lower oil hole 23 can be improved.

[0049] In some embodiments, the air passage 20 includes a curved portion 26 and a flat portion 25 continuously arranged. 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 41 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 arranging 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. 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 is 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.

[0050] In some embodiments, the heating element 40 further includes an electrode portion 42, which is at least disposed at the top or bottom of the heating element 41, and the electrode portion 42 extends along the width direction of the air passage 20 (e.g., Figure 2 The electrode portion 42 is clamped between the oil guide body 30 and the flat portion 25 (as shown in the x-direction). By extending the electrode portion 42 to the flat portion 25, the second surface 22 of the flat portion 25 and the third surface 31 of the oil guide body 30 can jointly clamp the electrode portion 42. The flat portion 25 and the third surface 31 are flat, which increases the clamping force on the electrode portion 42, preventing the heating element 40 from falling off between the oil guide body 30 and the air passage 20, and improving the installation stability of the heating element 40. By clamping the electrode portion 42, the normal operation of the heating element 41 is not affected, improving the reliability of the heating element 40. For example, the electrode portion 42 can be provided at either the top or bottom of the heating element 41, or simultaneously at both the top and bottom of the heating element 41; this is not limited here.

[0051] In some embodiments, the second surface 22 of the flat portion 25 is provided with a limiting post 251, the electrode portion 42 is provided with a first mounting structure 421, the oil guide body 30 is provided with a second mounting structure 33, and the limiting post 251 is arranged in the first mounting structure 421 and the second mounting structure 33. Through the cooperation of the first mounting structure 421 of the electrode portion 42 and the limiting post 251 of the flat portion 25, the stability of the installation of the heating body 40 can be further improved, and the heating body 40 can be effectively prevented from being detached from the oil guide body 30 and the air channel member 20. The cooperation of the first mounting structure 421 and the flat portion 25 can also play a positioning role in the installation of the heating body 40, and the installation precision of the heating body 40 can be improved. By arranging the limiting post 251 to sequentially pass through the first mounting structure 421 and the second mounting structure 33, the oil guide body 30, the heating body 40, and the air channel member 20 can be assembled together, and the stability and reliability of the connection can be improved. For example, the first mounting structure 421 and the second mounting structure 33 can be mounting holes, limiting clamping grooves, or the like.

[0052] In some embodiments, referring to Figure 5 , the electrode portion 42 is further provided with a bending portion 422, the bending portion 422 extends along the second surface 22 to the bottom of the flat portion 25, and the electronic atomization device 100 further includes a base 60 and an electrode 61, the base 60 is connected to the bottom of the air channel member 20, the electrode 61 is arranged in the base 60, and one end of the electrode 61 abuts against the bending portion 422. By using the bending portion 422, on the one hand, the contact area of the heating body 40 and the air channel member 20 can be increased, and the connection strength of the heating body 40 and the air channel member 20 can be enhanced. On the other hand, when the base 60 and the air channel member 20 are assembled with each other, one end of the electrode 61 can abut against the bottom of the air channel member 20. By extending the bending portion 422 to the bottom of the air channel member 20, the bending portion 422 and the electrode 61 can be electrically connected, and the electrode 61 can supply power to the heating body 40. The bending portion 422 can also increase the contact area of the electrode portion 42 and the electrode 61, avoid the problem of poor contact between the heating body 40 and the electrode 61, and improve the reliability of the electrical connection. Optionally, the air channel member 20 and the base 60 can be provided with buckle structures 62 (such as clamping holes and clamping hooks or clamping protrusions) to facilitate the clamping connection of the air channel member 20 and the base 60 with each other.

[0053] In some embodiments, the heating portion 41 and the oil outlet hole 23 are arranged in a staggered manner along the width direction of the oil guide body 30 (for example, the x direction shown in Figure 2 . In this way, there is a certain distance between the heating portion 41 and the oil outlet hole 23, and the atomization medium flowing out of the oil outlet hole 23 can first flow a certain distance in the oil guide body 30 along the width direction of the oil guide body 30, and then reach the position of the heating portion 41. This helps to avoid the heating portion 41 being aligned with the oil outlet hole 23, thereby avoiding the problem that the heating portion 41 is directly soaked in the atomization medium, causing too much atomization medium and insufficient atomization.

[0054] In some embodiments, the heating portion 41 has a minimum distance D with the edge of the oil outlet hole 23, 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 in the above range, on the one hand, it can ensure that the heating portion 41 has sufficient distance with the oil outlet hole 23, avoiding the heating portion 41 being directly immersed in the atomization medium; on the other hand, it can ensure that the heat generated by the heating portion 41 can be transmitted to the edge of the oil outlet hole 23, playing a preheating role on the atomization medium.

[0055] In some embodiments, the air passage piece 20 includes two plane portions 25, the two plane portions 25 are respectively connected to the two sides of the curved surface portion 26, and the second surface 22 of the plane portion 25 is further provided with a fixing arm 252, the fixing arm 252 is arranged in a direction away from the first surface 21 (for example, the negative direction of the y-axis as shown in the figure), and the oil guide body 30 is arranged between the two fixing arms 252. By arranging the oil guide body 30 between the two fixing arms 252, the connection strength between the air passage piece 20 and the oil guide body 30 can be further enhanced, avoiding the mutual separation of the oil guide body 30 and the air passage piece 20, and improving the installation reliability between the air passage piece 20 and the oil guide body 30.

[0056] In some embodiments, the wall thickness of the curved surface portion 26 is greater than the wall thickness of the plane portion 25. In this way, the plane portion 25 has a relatively thin thickness, on the one hand, it helps to reduce the opening depth of the oil outlet hole 23, facilitating the smooth flow of the atomization medium to the third surface 31 of the oil guide body 30, on the other hand, it can improve the heat conduction effect, the heating effect of the heating body 40 helps to conduct through the plane portion 25 to the atomization medium located around the oil outlet hole 23, thereby playing a preheating effect on the atomization medium. The curved surface portion 26 is provided with a relatively large wall thickness, which helps to improve the structural strength of the atomization channel 24, avoiding the deformation of the atomization channel 24.

[0057] In some embodiments, please refer to Figure 6 and Figure 7 ​The electronic atomization device 100 further comprises a sealing member 50 sleeved outside the oil guiding body 30 and the air passage member 20, the sealing member 50 is arranged in the oil cup 10, the sealing member 50 is provided with a ventilation opening 51 communicated with the atomization channel 24, and the sealing member 50 is further provided with a lower oil window 52 communicated with the lower oil hole 23, the lower oil window 52 is communicated with the liquid storage cavity 11. By arranging the sealing member 50, on the one hand, the air passage member 20, the heating body 40 and the oil guiding body 30 can be further fixed, the sealing member 50 is sleeved outside the oil guiding body 30 and the air passage member 20, so that the connection strength between the oil guiding body 30 and the air passage member 20 can be improved, so that the heating body 40 can be better maintained between the air passage member 20 and the oil guiding body 30. On the other hand, the sealing member 50 is assembled with the oil cup 10, so that the liquid storage cavity 11 can be sealed, the lower oil window 52 of the sealing member 50 can allow the atomization medium to pass through, so that the atomization medium can flow to the lower oil hole 23, and the remaining positions of the sealing member 50 do not allow the atomization medium to pass through, so as to seal the liquid storage cavity 11.

[0058] In some embodiments, a fourth surface 32 opposite to the third surface 31 is arranged along the thickness direction (e.g., the y direction shown) of the oil guiding body 30, and an inner side surface of the sealing member 50 facing the fourth surface 32 is provided with a liquid locking groove 53, and the fourth surface 32 covers the groove opening of the liquid locking groove 53. Figure 3 By arranging the liquid locking groove 53, the atomization medium adsorbed in the oil guiding body 30 can be prevented from leaking from the fourth surface 32, and by connecting the fourth surface 32 with the liquid locking groove 53, the liquid locking groove 53 can lock and seal the atomization medium penetrating out of the fourth surface 32 of the oil guiding body 30, so as to prevent the atomization medium from leaking under the action of gravity. In this way, the atomization medium leaking out of the fourth surface 32 can also be sealed in the liquid locking groove 53, so as to ensure that the electronic atomization device 100 has good sealing performance.

[0059] For example, a part of the oil guiding body 30 can cover the groove opening of the liquid locking groove 53, and another part of the oil guiding body 30 is located outside the groove opening of the liquid locking groove 53. Alternatively, a part of the oil guiding body 30 can be embedded in the liquid locking groove 53, and the remaining part is located outside the groove opening of the liquid locking groove 53. Alternatively, the entire oil guiding body 30 is embedded in the liquid locking groove 53 and covers the groove opening of the liquid locking groove 53, and the specific arrangement mode is not limited.

[0060] In some embodiments, at least one protruding structure 531 is arranged in the liquid locking groove 53, a projection of the protruding structure 531 along the thickness direction of the oil guiding body 30 is located in the heating body 40, the protruding structure 531 abuts against the fourth surface 32, and the protruding structure 531 is arranged in the liquid locking groove 53. Figure 4The protruding structure 531 can extrude the oil guide body 30 towards the heating body 40 when the sealing member 50 is assembled with the oil guide body 30 and the air passage member 20, i.e., the protruding structure 531 can extrude the oil guide body 30 towards the heating body 40 in a compressed state. The extrusion of the protruding structure 531 can extrude the oil guide body 30 towards the heating body 40, thereby improving the tightness of the heating body 40 and the oil guide body 30, avoiding the problem of dry burning of the heating body 40 due to poor contact between the heating body 40 and the oil guide body 30, and improving the reliability of the heating body 40 and the oil guide body 30. Alternatively, the protruding structure 531 can be a block-shaped structure such as a hemisphere, a cone, a circular truncated cone, a prismatic truncated cone, or a strip structure, which is not limited here.

[0061] For example, when a plurality of protruding structures 531 are arranged in the liquid locking groove 53, the plurality of protruding structures 531 can be arranged at intervals, for example, in an array. The cross-sectional area of the protruding structure 531 can be arranged to gradually decrease in a direction away from the bottom of the liquid locking groove 53, which facilitates the protruding structure 531 to be easily demolded when the sealing member 50 is formed.

[0062] In order to balance the air pressure in the liquid storage cavity 11, so that the atomized medium can continuously and automatically flow out, in some embodiments, the air passage member 20 is provided with a gas return structure 27 for connecting the liquid storage cavity 11 to the outside atmosphere.

[0063] In some embodiments, the gas return structure 27 includes a gas return port 271 and a gas return groove 272. The gas return port 271 is arranged through the first surface 21 and the second surface 22, and is connected to the liquid storage cavity 11. The gas return port 271 is arranged at intervals with the oil outlet hole 23. A part of the gas return groove 272 is arranged at the connection between the first surface 21 and the second surface 22. One end of the gas return groove 272 is connected to the side of the gas return port 271 facing the oil guide body 30. The other end of the gas return groove 272 is connected to the atomization channel 24 or is used to be connected to the outside atmosphere. By arranging the gas return structure 27, the air of the outside atmosphere can enter the liquid storage cavity 11, so that the liquid storage cavity 11 can balance the internal and external air pressure by supplementing air after part of the atomized medium flows out, ensuring that the atomized medium can continuously and smoothly flow out of the oil outlet hole 23, and ensuring the smoothness of the oil outlet of the oil outlet hole 23. By arranging the gas return groove 272 at the connection between the first surface 21 and the second surface 22 of the air passage member 20, on the one hand, the gas return groove 272 can be connected to the gas return port 271, ensuring that the gas return groove 272 can provide air to the gas return port 271, and on the other hand, the space occupied by the gas return groove 272 in the air passage member 20 can be saved, making the gas return structure 27 more compact. The gas return port 271 is arranged at intervals with the oil outlet hole 23, which can avoid the air bubbles generated by the gas return port 271 from blocking the oil outlet hole 23, and improve the smoothness of the oil outlet of the oil outlet hole 23.

[0064] Optionally, the air return port 271 is positioned above the oil drain hole 23 along the direction of gravity. This way, the bubbles generated by the air return port 271 can rise in the atomizing medium without passing through the oil drain hole 23, further reducing the risk of the oil drain hole 23 being blocked by bubbles and ensuring the smooth and reliable flow of oil from the oil drain hole 23.

[0065] 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.

[0066] As an alternative implementation, in addition to the above-described arrangement, the return air structure 27 can also be installed on the air passage 20 along the thickness direction of the air passage (e.g., ...). Figure 2 A through groove (not shown) is provided in the y direction. One end of the through groove extends through to the first surface 21 of the air passage 20, and the other end extends through to the second surface 22 of the air 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.

[0067] In some embodiments, 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 a 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.

[0068] For example, please refer to Figure 8In the assembly of the electronic atomization device 100, the heating body 40 and the oil guide body 30 can be sequentially installed into the air channel member 20, the oil guide body 30 and the air channel member 20 jointly clamping the heating body 40, and the heating body 40, the oil guide body 30 and the air channel member 20 are assembled to form a first assembly structure 101. Then, the sealing member 50 is sleeved on the outer periphery of the first assembly structure 101 to form a second assembly structure 102. At the same time, the electrode 61 and the magnet and other structures in the base 60 can be installed. Then, the second assembly structure 102 and the base 60 are assembled, specifically, the bottom of the air channel member 20 and the base 60 are connected to each other, and the side buckle of the air channel member 20 and the buckle on the base 60 are buckled to each other, so that the second assembly structure 102 and the base 60 are installed to form a third assembly structure 103. Finally, the atomization medium is injected into the oil cup 10, the third assembly structure 103 is installed into the opening of the oil cup 10, and the sealing member 50 is sealingly connected to the inner wall of the oil cup 10 to avoid leakage of the atomization medium from the opening of the oil cup 10. By using this arrangement, the assembly of the electronic atomization device 100 can be completed through the above several assemblies, the assembly steps of the electronic atomization device 100 are simplified, and the assembly efficiency of the electronic atomization device 100 is improved.
