[0002] The electronic atomization device is generally provided with a liquid storage cavity, an oil guide body in communication with the liquid storage cavity, and a heating body arranged on the surface of the oil guide body. The liquid storage cavity stores liquid atomization medium. The oil guide body adsorbs the atomization medium and conducts the atomization medium to the position of the heating body. Under the heating action of the heating body, the atomization medium is heated and atomized to form an aerosol for the user to inhale.

[0003] In the related art, the liquid storage cavity is provided with a lower oil hole. The oil guide body is directly arranged at the position of the lower oil hole to adsorb the atomization medium.

If it is described that the first, second, and the like are only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of indicated technical features.

[0040] In the description of the present application, if the description of the terms "as an embodiment", "an embodiment", "some examples", "some embodiments", "illustrative embodiments", "example", "specific example", "some examples" and the like appears, it means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the present application. In the present description, 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] In the related art, an electronic atomization device is usually provided with a liquid storage cavity, an oil guide body and a heating body. The liquid storage cavity is provided with a lower oil hole. The liquid storage cavity stores liquid atomization medium. The oil guide body is directly arranged at the position of the lower oil hole to adsorb the atomization medium. The surface of the oil guide body facing the lower oil hole is a liquid adsorption surface. The heating body is arranged on the other surface (i.e. atomization surface) of the oil guide body. The oil guide body adsorbs the atomization medium. Under the heating action of the heating body, the atomization medium is heated and atomized to form an aerosol which is released from the atomization surface.

Generally, in the electronic atomization device in which the liquid guide body and the heating body are vertically placed, the liquid adsorption surface and the atomization surface are arranged on two different surfaces of the oil guide body, for example, two adjacent or opposite surfaces. Therefore, using this arrangement means that there is at least a certain interval between the airflow channel and the lower oil hole, thereby increasing the horizontal space occupation in the electronic atomization device, which is not conducive to improving the internal space utilization rate of the electronic atomization device.

[0042] To solve the above 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 is not a specific limitation on the present application.

[0043] Embodiment one

[0044] 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 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 component 20. The third surface 31 partially covers the lower oil hole 23, and the third surface 31 and the second surface 22 surround and form an atomizing channel 24 communicating with the air outlet 14. The air outlet 14 and the atomizing channel 23 are along the longitudinal direction (e.g., Figure 2 Extending in the z direction (as shown), the heating element 40 is disposed on the third surface 31 of the oil guide body 30, and the heating element 40 is located in the atomization channel 24.

[0045] 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 adding a structural component for the lower oil hole 23 on the side of the oil guide body 30 away from the heating element 40, thus making the electronic atomizing device 100 structurally simpler. This not only reduces the horizontal (e.g.) Figure 2 The structure dimensions (shown in the y-direction) not only allow for greater space in the design of the lower oil hole 23 and the liquid storage chamber 11, but also increase the liquid storage capacity of the electronic atomizing device 100.

[0046] In some embodiments, the airway piece 20 comprises a curved portion 26 and a planar portion 25 arranged in sequence, the planar portion 25 is connected with the third surface 31, the curved portion 26 is arranged in a spaced manner with the third surface 31 to form the atomization channel 24, and the heating body 40 is arranged corresponding to the curved portion 26. The oil outlet hole 23 can be arranged in the planar portion 25 or at the joint of the planar portion 25 and the curved portion 26. By arranging the planar portion 25 and the curved portion 26 in sequence, when the planar portion 25 is arranged in abutment with the third surface 31 of the oil guide body 30, the curved portion 26 can be arranged in a spaced manner with the third surface 31, and the third surface 31 and the curved portion 26 enclose to form the atomization channel 24. The heating body 40 is arranged corresponding to the curved portion 26, so that the heating body 40 can be exposed in the atomization channel 24, and the aerosol formed by the atomization medium heated and atomized by the heating body 40 can be released into the atomization channel 24. By connecting the planar portion 25 of the airway piece 20 with the oil guide body 30, the contact area of the airway piece 20 and the oil guide body 30 can be increased, and the connection strength of the two can be improved. The third surface 31 of the oil guide body 30 can be arranged in abutment on the second surface 22 of the planar portion 25 and can cover the oil outlet hole 23, which helps the atomization medium to flow through the oil outlet hole 23 and reach the third surface 31 of the oil guide body 30, and ensures that the atomization medium can be absorbed by the oil guide body 30.

[0047] Exemplarily, the third surface 31 of the oil guide body 30 is arranged in a planar manner, which is helpful for installation and cooperation with the planar portion 25 of the airway piece 20.

[0048] Of course, as an alternative embodiment, the oil guide body 30 is arranged in a curved manner, and the curved portion of the oil guide body 30 encloses with the airway piece 20 to form the atomization channel 24. Alternatively, the airway piece 20 can be arranged in a planar manner, and the oil guide body 30 is arranged in a curved manner, so that the airway piece 20 and the oil guide body 30 enclose to form the atomization channel 24, which is not limited herein.

[0049] In some embodiments, the wall thickness of the curved portion 26 is greater than the wall thickness of the planar portion 25. In this way, the planar portion 25 has a relatively thin thickness, which on the one hand helps to reduce the opening depth of the oil outlet hole 23, and facilitates the smooth flow of the atomization medium to the third surface 31 of the oil guide body 30, and on the other hand can improve the heat conduction effect, and the heating effect of the heating body 40 helps to conduct through the planar portion 25 to the atomization medium around the oil outlet hole 23, thereby achieving the effect of preheating the atomization medium. By arranging a relatively large wall thickness of the curved portion 26, the structural strength of the atomization channel 24 can be improved, and deformation of the atomization channel 24 can be avoided.

[0050] In some embodiments, the heating body 40 comprises a heating portion 41, and the heating portion 41 is arranged along the width direction of the oil guide body 30 (such as the direction perpendicular to the length direction of the oil guide body 30) corresponding to the oil outlet hole 23. Figure 2The heating portion 41 is arranged to be misaligned with the lower oil hole 23 in the x direction. In this way, there is a certain distance between the heating portion 41 and the lower oil hole 23, and when the atomization medium flows out of the lower oil hole 23, it can first flow a certain distance in the width direction of the oil guide body 30 in 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 lower oil hole 23, thereby avoiding the problem of the heating portion 41 being directly immersed in the atomization medium, causing excessive atomization medium and insufficient atomization.

[0051] In some embodiments, the heating portion 41 and the edge of the lower oil hole 23 have a minimum distance D, and 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 can ensure that there is enough distance between the heating portion 41 and the lower oil hole 23, and avoid 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 lower oil hole 23, thereby playing a preheating role on the atomization medium.

[0052] Preferably, 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 in the above range can not only avoid the heating portion 41 being too much immersed in the atomization medium due to the specific distance between the heating portion 41 and the lower oil hole 23 being too small, but also ensure that the heat generated by the heating portion 41 can be transmitted to the edge of the lower oil hole 23.

[0053] In some embodiments, the heating body 40 includes the heating portion 41 and the electrode portion 42 connected to each other, the heating portion 41 is arranged corresponding to the curved portion 26 to be exposed in the atomization channel 24, the second surface 22 of the flat portion 25 is provided with a limiting column 251, and the electrode portion 42 is provided with a first mounting structure 421, and the first mounting structure 421 is connected with the limiting column 251 in a matched manner to connect the heating body 40 to the airway piece 20. The oil guide body 30 and the flat portion 25 of the airway piece 20 jointly clamp the heating body 40, which helps to stably install the heating body 40 between the oil guide body 30 and the airway piece 20. Through the cooperation of the first mounting structure 421 of the electrode portion 42 and the limiting column 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 pulled out from the oil guide body 30 and the airway piece 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 improve the installation precision of the heating body 40. For example, the first mounting structure 421 can be a mounting hole, a limiting clamping groove, etc.

[0054] In some embodiments, the oil guide body 30 corresponding to the limiting column 251 is also provided with a second mounting structure 33. When the oil guide body 30 is mounted with the air passage piece 20, the limiting column 251 can penetrate into the second mounting structure 33, realizing the connection of the oil guide body 30 with the air passage piece 20. Specifically, the limiting column 251 penetrates through the first mounting structure 421 and the second mounting structure 33 in sequence, so that the oil guide body 30, the heating body 40 and the air passage piece 20 can be assembled together, improving the stability and reliability of the connection. Exemplarily, the second mounting structure 33 can be a mounting hole, a limiting clamping groove or the like.

[0055] 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 piece 20 is provided with a gas return structure 27 for connecting the liquid storage cavity 11 to the outside atmosphere.

[0056] 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 in a spaced manner with the oil outlet hole 23. 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, and 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 after a part of the atomized medium flows out, the liquid storage cavity 11 can balance the internal and external air pressure by supplementing air, ensuring that the atomized medium can continuously and smoothly flow out from 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 piece 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 piece 20 can be saved, making the gas return structure 27 more compact. The gas return port 271 is arranged in a spaced manner 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, improving the smoothness of the oil outlet of the oil outlet hole 23.

[0057] Optionally, the gas return port 271 is arranged above the oil outlet hole 23 along the direction of gravity (such as the z direction shown), so that the air bubbles generated by the gas return port 271 can not pass through the oil outlet hole 23 during the rising process in the atomized medium, further reducing the risk of the oil outlet hole 23 being blocked by the air bubbles, and ensuring the smoothness and reliability of the oil outlet of the oil outlet hole 23. Figure 2

[0058] ​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.

[0059] 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.

[0060] In some embodiments, please refer to Figures 5 to 7 The electronic atomizing device 100 also includes a sealing element 50, which is disposed inside the oil cup 10 and 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 setting the sealing element 50, the air passage component 20, the heating element 40, and the oil guide body 30 can be further fixed. By sleeved 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.

[0061] In some embodiments, along the thickness direction of the oil guide body 30 (e.g. Figure 2The fourth surface 32 opposite to the third surface 31 is provided with a liquid locking groove 53, and the inner side surface of the sealing member 50 facing the fourth surface 32 is provided with the liquid locking groove 53. By providing the liquid locking groove 53, the leakage of the atomized medium adsorbed in the oil guide body 30 from the fourth surface 32 can be avoided. By connecting the fourth surface 32 and the liquid locking groove 53, the liquid locking groove 53 can lock and seal the atomized medium that penetrates from the fourth surface 32 of the oil guide body 30, thereby avoiding the leakage of the atomized medium under the action of gravity. In this way, the leakage of the atomized medium from the fourth surface 32 can be avoided, and the atomized medium can also be sealed in the liquid locking groove 53, thereby ensuring that the electronic atomization device 100 has good sealing performance.

[0062] Exemplarily, a part of the oil guide body 30 can cover the slot of the liquid locking groove 53, and another part of the oil guide body 30 is located outside the slot of the liquid locking groove 53. Alternatively, a part of the oil guide body 30 can be embedded in the liquid locking groove 53, and the remaining part is located outside the slot of the liquid locking groove 53. Alternatively, the entire oil guide body 30 is embedded in the liquid locking groove 53 and covers the slot of the liquid locking groove 53, and the specific arrangement mode is not limited.

[0063] In some embodiments, at least one protruding structure 531 is arranged in the liquid locking groove 53, the projection of the protruding structure 531 in the thickness direction of the oil guide body 30 is located in the heating body 40, the protruding structure 531 abuts against the fourth surface 32, and the protruding structure 531 compresses the oil guide body 30 in the thickness direction of the oil guide body 30 (such as the y direction shown in the figure). Figure 4 That is, when the sealing member 50 is assembled with the oil guide body 30 and the air duct member 20, the protruding structure 531 can extrude the oil guide body 30 towards the heating body 40, and the oil guide body 30 is in a compressed state. By using the extrusion effect of the protruding structure 531, the oil guide body 30 can be extruded to one side of 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 caused by poor contact between the heating body 40 and the oil guide body 30, and improving the use reliability of the heating body 40 and the oil guide body 30.

[0064] 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 arranged in extension, which is not limited here. 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 the direction away from the bottom of the liquid locking groove 53, which is helpful for the protruding structure 531 to be easily demolded when the sealing member 50 is formed.

[0065] 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.

[0066] In some embodiments, please refer to Figure 7 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.

[0067] For example, please refer to Figure 8 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 the first assembly structure 101. Next, the sealing element 50 is fitted onto the outer periphery of the first assembly structure 101 to form the second assembly structure 102. At the same time, the electrode 61, magnet, and other structures can be installed in the base 60. Then, 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 the 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.

[0068] Example 2

[0069] Please combine Figure 7 and Figure 9This 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 is provided with 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 is provided with an air vent 51 and an oil inlet 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 inlet hole 23 penetrating the first surface 21 and the second surface 22. The oil inlet hole 23 communicates with the oil inlet window 52 and communicates with the liquid storage chamber 11 through the oil inlet window 52. The first surface 21 is the surface that contacts the liquid in the liquid storage chamber 11. Oil guide body 30 is disposed within sealing member 50 and on the second surface 22 of air passage member 20. 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 enclose each other to form a longitudinal (e.g., Figure 9 The atomizing channel 24 extends in the z-direction (as shown), and the atomizing channel 24 is connected to the air outlet 14 through the air vent 51. The heating element 40 is disposed on the third surface 31 of the oil guide body 30, and the heating element 40 is located in the atomizing channel 24.

[0070] 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 eliminates the need for adding a lower oil hole 23 to the side of the oil guide 30 away from the heating element 40, thus simplifying the structure of the atomizing assembly and reducing the impact on the horizontal direction (e.g., Figure 9 The structural dimensions (shown in the y-direction) not only allow for greater space in the design of the lower oil hole 23 and the liquid storage chamber 11, but also increase the liquid storage capacity of the liquid storage chamber 11.

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.
