[0093] The embodiments of the present application will be described in detail below with reference to the drawings. The embodiments described with reference to the drawings are exemplary, and the following description refers to the accompanying drawings in which Figures 1-18 A description is given of the atomization device 100 for an electronic cigarette according to the first embodiment of the present application.

[0094] As shown in Figures 1-3 and Figures 17-18 The atomization device 100 for an electronic cigarette according to the first embodiment of the present application includes a housing 1 and an atomization core fixing member 2.

[0095] Specifically, the housing 1 is provided with an oil storage chamber 11, an air passage 12, and an atomization chamber 13 communicating with the air passage 12, the housing 1 is provided with at least one air inlet 1521 communicating with the atomization chamber 13 and an air suction port 141 communicating with the air passage 12, the air inlet 1521 is located on the side surface of the housing 1, and the housing 1 has a length direction (the direction indicated by arrow A in the figure), a width direction (the direction indicated by arrow B in the figure), and a thickness direction (the direction indicated by arrow C in the figure). The atomization core fixing member 2 is arranged in the housing 1, the atomization core fixing member 2 separates the oil storage chamber 11 and the atomization chamber 13, the atomization core fixing member 2 is provided with an atomization core, the atomization core respectively communicates with the oil storage chamber 11 and the atomization chamber 13, and the atomization core is used for atomizing the medium to be atomized in the oil storage chamber 11.

[0096] For example, in Figures 1-3 In an example, the air passage 12 is formed in the middle of the housing 1, the oil storage chamber 11 is arranged around the air passage 12, the atomization chamber 13 is located below the oil storage chamber 11, and the atomization core is arranged between the oil storage chamber 11 and the atomization chamber 13. The oil storage chamber 11 is used for containing the medium to be atomized such as tobacco tar, and the atomization core can atomize the medium to be atomized to form smoke (including but not limited to aerosol, suspended liquid, low-temperature vapor, and volatile gas). The air inlet 1521 can be formed on the outer circumferential side of the housing 1, that is, the air inlet 1521 can be formed on the outer circumferential surface of the housing 1, and the air inlet 1521 communicates with the atomization chamber 13. Because the bottom of the housing 1 can store a certain amount of tobacco tar, the air inlet 1521 arranged on the outer circumferential surface of the housing 1 can avoid leakage of the tobacco tar in the atomization chamber 13, thereby improving the user experience.

[0097] Referring to Figure 7 and Figure 8 in combination with Figure 1 and Figure 2 , the atomization core fixing member 2 and the inner wall of the housing 1 define at least one atomization guide channel 21 which is separated from the oil storage chamber 11 and communicates the air passage 12 with the atomization chamber 13. When the atomization device 100 works, the atomization medium mixture in the atomization chamber 13 can flow to the air passage 12 through the atomization guide channel 21, and flow to the user's oral cavity through the air suction port 141. As Figure 1 and Figure 2As shown, the thickness direction size of the shell 1 is D, the length direction size of the shell 1 is L, and the width direction size of the shell 1 is W, wherein D, L and W satisfy: L > W ≥ D, 5 ≤ L / D ≤ 9, and 2 ≤ W / D ≤ 5. For example, when L / D < 5 or W / D < 2, the thickness direction size of the shell 1 is large, which increases the volume of the atomization device 100, and is not conducive to the ultra-thin design of the atomization device 100; when L / D > 9 or W / D > 5, the thickness direction size of the shell 1 is small, which leads to a small internal space of the shell 1, so that other components in the shell 1, such as the atomization core fixing member 2, need to be designed to be small in size, thereby increasing the processing difficulty and being not conducive to the assembly of the atomization device 100. Therefore, when D, L and W satisfy: 5 ≤ L / D ≤ 9, and 2 ≤ W / D ≤ 5, the atomization device 100 can meet the ultra-thin design, and the processing is convenient, thereby improving the assembly efficiency of the atomization device 100.

[0098] L > W ≥ D, that is, the length direction size of the shell 1 is greater than the width direction and thickness direction sizes of the shell 1, and the width direction size of the shell 1 is greater than or equal to the thickness direction size of the shell 1. When the width direction size of the shell 1 is greater than the thickness direction size of the shell 1, the maximum size of the shell 1 along the thickness direction C is the smallest, the shell 1 is flat, and the maximum size of the shell 1 along the length direction A is greater than the maximum size of the shell 1 along the width direction B. When the atomization device 100 is applied to an electronic cigarette as a cartridge, the length direction A is usually consistent with the length direction of the cigarette rod, that is, the length direction A is the extension direction from the cartridge to the cigarette rod.

[0099] The working process of the atomization device 100 when applied to an electronic cigarette is described below by way of example.

[0100] After the atomization device 100 is combined with the cigarette rod, the user inhales through the air inlet 141, at this time, the pneumatic sensor (such as a microphone) in the cigarette rod senses, so that the power supply in the cigarette rod and the atomization core are electrically connected, and the atomization core works, for example, the atomization core is heated, the atomization medium in the oil storage chamber 11, such as tobacco tar, moves towards the atomization chamber 13 and is heated by the atomization core, and the smoke is formed in the atomization chamber 13. At the same time, the external air enters the atomization chamber 13 through the air inlet 1521 and mixes with the smoke in the atomization chamber 13, and the mixed smoke is inhaled by the user through the air inlet 141 and the atomization guide channel 21 and the air channel 12, thereby meeting the user's use requirements. When the user stops inhaling from the air inlet 141, the atomization medium in the oil storage chamber 11, such as tobacco tar, will stop entering the atomization chamber 13 from the atomization core, so as to avoid the ineffective consumption of the atomization medium in the oil storage chamber 11, thereby improving the utilization rate of the atomization medium. It should be explained here that some electronic cigarettes are designed as a split structure, and the atomization device 100 and the cigarette rod are detachably combined, and some electronic cigarettes are designed as a non-detachable structure, which is not limited here.

[0101] According to the atomization device 100 of the embodiment of the present application, the air inlet 1521 is arranged on the side of the shell 1, and the air exchange passage is arranged between the atomization core fixing member 2 and the atomization core, and the air exchange passage is in communication with the oil storage chamber 11 and the atomization chamber 13 respectively, and D, L and W satisfy: L > W ≥ D, 5 ≤ L / D ≤ 9, and 2 ≤ W / D ≤ 5. Thus, compared with the conventional atomization device, the applicant of the present application finds through multiple tests that the size design of the cartridge as above can make full use of the internal space of the electronic cigarette, and can maximize the thin design of the electronic cigarette while ensuring a small resistance, that is, the atomization device 100 can be designed into a super-thin style, and the user has a good experience when holding, carrying and inhaling.

[0102] According to some embodiments of the present application, as shown in Figure 2 D further satisfies: 5.0 mm ≤ D ≤ 9.0 mm. When D < 5.0 mm, the thickness of the shell 1 is relatively small, thereby reducing the internal space of the shell 1, so that other components in the shell 1, for example, the atomization core fixing member 2, need to be designed to be small in size, which not only has a large processing difficulty, but also has a large assembly difficulty of the atomization core, and the overall atomization efficiency of the electronic cigarette is low; when D > 9.0 mm, the thickness of the shell 1 is relatively large, and the user has a poor experience when holding and inhaling. Thus, by making D satisfy: 5.0 mm ≤ D ≤ 9.0 mm, the processing difficulty is reduced, the atomization efficiency is ensured, the atomization device 100 can meet the user's demand for super-thin design, and the assembly efficiency of the atomization device 100 can be improved. Further, D further satisfies: 6.0 mm ≤ D ≤ 8.0 mm.

[0103] According to some embodiments of the present application, as shown in Figure 10 The size of the atomization core 3 in the width direction of the shell 1 is the length L1 of the atomization core 3, and the size of the atomization core 3 in the thickness direction of the shell 1 is the width w1 of the atomization core 3, wherein L1 and w1 satisfy: 2 ≤ L1 / w1 ≤ 5. If L1 / w1 is greater than 5, the size of the atomization core 3 in the width direction is relatively small, thereby possibly causing the size of the groove 31 to be small, and when the atomization core 3 is used to atomize the medium to be atomized in the oil storage chamber 11, the medium to be atomized is not easy to enter the groove 31, and the atomization effect can be poor. If the ratio of L1 to w1 is less than 2, the width size of the atomization core 3 is relatively large, which can cause the thickness of the atomization device 100 to be large, and is not conducive to the thin design of the atomization device 100. Thus, by setting the ratio of L1 to w1 to satisfy: 2 ≤ L1 / w1 ≤ 5, the atomization device 100 can have a good atomization effect, and the thickness of the atomization device 100 can be designed to be thinner.

[0104] According to some embodiments of the present application, as shown in Figure 10The size of the atomizing core 3 in the thickness direction of the shell 1 is the width w1 of the atomizing core 3, wherein w1 satisfies 2mm≤w1≤3.5mm. If w1 is greater than 3.5mm, the size of the atomizing core 3 in the width direction is large, which may cause the thickness of the atomizing device 100 to be large, and increase the thickness of the atomizing device 100. If w1 is less than 2mm, the size of the atomizing core 3 in the width direction is small, which may cause the size of the groove 31 to be small, and the atomizing core 3 to be unable to atomize the medium to be atomized in the oil storage chamber 11, and the atomization effect of the atomizing device 100 to be poor. Therefore, by setting w1 to satisfy 2mm≤w1≤3.5mm, the atomization effect of the atomizing device 100 is ensured, and the thickness of the atomizing device 100 can be designed to be thinner.

[0105] According to some embodiments of the present application, the side surface of the atomizing core facing the oil storage chamber 11 is provided with a groove 31, and the thickness of the bottom wall of the groove 31 of the atomizing core is t1, wherein t1 satisfies 0.6mm≤t1≤2.5mm. If t1<0.6mm, the thickness of the bottom wall of the groove 31 of the atomizing core is small, and the mechanical strength of the bottom wall of the groove 31 of the atomizing core is weak. Therefore, when the atomizing core atomizes the medium to be atomized in the oil storage chamber 11, the bottom wall of the groove 31 of the atomizing core may be deformed or broken, and the safety performance of the atomizing device 100 is reduced. If t1>2.5mm, the thickness of the bottom wall of the groove 31 of the atomizing core is large, and the medium to be atomized is not easy to penetrate through the bottom wall of the groove 31 of the atomizing core, and the atomization efficiency of the atomizing device 100 is reduced. Therefore, by setting t1 to satisfy 0.6mm≤t1≤2.5mm, the atomization efficiency of the atomizing device 100 is improved, and the safe use of the atomizing device 100 is ensured.

[0106] According to some embodiments of the present application, the thickness of the side wall of the groove 31 of the atomizing core is t2, wherein t2 satisfies 0.6mm≤t2≤1.5mm. If t2<0.6mm, the thickness of the side wall of the groove 31 of the atomizing core is small, and the medium to be atomized may not be fully atomized. If t2>1.5mm, the thickness of the side wall of the groove 31 of the atomizing core is large, and the medium to be atomized is not easy to pass through the atomizing core, and the atomization efficiency is reduced. Therefore, by setting t2 to satisfy 0.6mm≤t2≤1.5mm, the atomization is effectively ensured, and the atomization efficiency of the atomizing device 100 is improved.

[0107] According to some embodiments of the present application, as shown in FIG. 1, the atomizing device 100 comprises an atomizing core 3 and an atomizing shell 1, and the atomizing core 3 is arranged in the atomizing shell 1. Figure 10As shown, the thickness of the side wall of the corresponding groove 31 of the atomizing core 3 is t2, wherein w1, t2 satisfy: 2.5≤w1 / t2≤6. If w1 / t2 is greater than 6, the proportion of the thickness of the side wall of the corresponding groove 31 of the atomizing core 3 in the width of the atomizing core 3 is small, and the thickness of the side wall of the corresponding groove 31 of the atomizing core 3 is thin. In this way, when the atomizing core 3 is used to atomize the medium to be atomized in the oil storage chamber 11, the side wall of the corresponding groove 31 of the atomizing core 3 can be deformed or broken, so that the safety performance of the atomizing device 100 is reduced. If w1 / t2 is less than 2.5, the proportion of the thickness of the side wall of the corresponding groove 31 of the atomizing core 3 in the width of the atomizing core 3 is large, and the thickness of the side wall of the corresponding groove 31 of the atomizing core 3 is large. In this way, the medium to be atomized is not easy to pass through the atomizing core 3, and the atomization efficiency is reduced. By setting w1, t2 to satisfy 2.5≤w1 / t2≤6, the ratio of the width of the atomizing core 3 to the thickness of the side wall of the corresponding groove 31 of the atomizing core 3 is moderate, the atomization efficiency of the atomizing device 100 is high, and the safety performance is good.

[0108] According to some embodiments of the present application, in combination with Figure 10 , the size of the groove 31 in the thickness direction of the shell 1 is the width w2 of the groove 31, wherein w1, w2 satisfy: 1.5≤w1 / w2≤6. If w1 / w2 is greater than 6, the proportion of the groove 31 in the width direction of the atomizing core 3 is small, and the thickness of the side wall of the corresponding groove 31 of the atomizing core 3 is large. In this way, the medium to be atomized is not easy to pass through the atomizing core 3, and the atomization efficiency is reduced. If w1 / w2 is less than 1.5, the proportion of the groove 31 in the width direction of the atomizing core 3 is large, and the thickness of the side wall of the corresponding groove 31 of the atomizing core 3 is thin, and the mechanical strength of the bottom wall of the corresponding groove 31 of the atomizing core 3 can be weak. In this way, when the atomizing core 3 is used to atomize the medium to be atomized in the oil storage chamber 11, the side wall of the corresponding groove 31 of the atomizing core 3 can be deformed or broken, so that the safety performance of the atomizing device 100 is reduced. By setting w1, w2 to satisfy 1.5≤w1 / w2≤6, the ratio of the width of the atomizing core 3 to the width of the groove 31 is moderate, the atomization efficiency of the atomizing device 100 is high, and the safety performance is good.

[0109] According to some embodiments of the present application, in combination with Figure 1 , Figure 3 , Figure 4 , Figure 16 and Figure 17The outer shell 1 comprises a shell 14 and a base assembly 15. The shell 14 is open at one end, and an air inlet 141 is formed at the other end of the shell 14. The base assembly 15 is arranged at the open end of the shell 14, and the base assembly 15 and the shell 14 define an oil storage chamber 11, an air passage 12 and an atomization chamber 13. The base assembly 15 comprises a base 151 and a base shell 152. The base shell 152 is arranged at a side of the base 151 away from the center of the outer shell 1. An air inlet 1521 is formed at the side of the base shell 152. An air inlet passage 1511 is formed in the base 151 and communicates with the air inlet 1521 and the atomization chamber 13.

[0110] As shown in Figure 3 , Figure 4 , Figure 16 and Figure 17 , the shell 14 is open at one end in the length direction, and the air inlet 141 is formed at the other end in the length direction of the shell 14. The base assembly 15 is arranged at the open end of the shell 14. The air inlet passage 1511 can be formed in the middle of the base 151 and extends along the length direction of the outer shell 1. The base shell 152 can be sleeved at the open end of the shell 14 by the buckle 1513 structure to limit the base 151 in the shell 14. Since the wall thickness of the base shell 152 is thin, the air inlet 1521 is arranged at the side of the base shell 152 to facilitate the processing of the air inlet 1521. When the atomization device 100 works, the external air can flow to the atomization chamber 13 through the air inlet 1521 and the air inlet passage 1511, and mix with the atomization medium in the atomization chamber 13.

[0111] Further, the air exchange passage is arranged between the atomization core fixing member 2 and the atomization core, and communicates with the atomization chamber 13 and the oil storage chamber 11 respectively. Since the atomization medium in the oil storage chamber 11 continuously flows to the atomization core when the atomization device 100 works, the oil storage chamber 11 is in a negative pressure state. At this time, the pressure of the oil storage chamber 11 is less than the pressure of the atomization chamber 13. The gas in the atomization chamber 13 flows to the air exchange passage and then flows to the oil storage chamber 11 through the air exchange passage, so as to maintain the balance between the pressure of the oil storage chamber 11 and the pressure of the atomization chamber 13. Thus, the atomization medium in the oil storage chamber 11 can continuously move to the atomization chamber 13 through the atomization core, so that the atomization core can obtain enough atomization medium to maintain the generation effect of the smoke.

[0112] According to the embodiments of the present application, by arranging the air exchange passage as above, the pressure difference between the oil storage chamber 11 and the atomization chamber 13 can be adjusted through the air exchange passage, so as to maintain the balance between the pressure of the oil storage chamber 11 and the pressure of the atomization chamber 13, to ensure the smooth conduction of the tobacco tar to the atomization core, and to prevent oil leakage.

[0113] According to some embodiments of the present application, as shown in Figure 1As shown, the side surface of the base 151 away from the oil storage compartment 11 and the inner wall of the base shell 152 are at least partially spaced apart from each other to define at least one communication passage 153, and the air inlet 1521 communicates with the air inlet passage 1511 through the communication passage 153. In this way, the communication passage 153 plays a guiding role, and external air can flow to the communication passage 153 through the air inlet 1521, and the air can quickly and smoothly flow to the air inlet passage 1511 under the guidance of the communication passage 153.

[0114] Further, at least one support 1512 is arranged on the side surface of the base 151 away from the oil storage compartment 11, the support 1512 abuts against the inner wall of the base shell 152, and at least a part of the outer circumferential surface of the support 1512 is spaced apart from the inner circumferential surface of the base shell 152 to define the communication passage 153. For example, in the examples of Figure 1 、 Figure 14 、 Figure 15 and Figure 16 , the side surface of the support 1512 away from the oil storage compartment 11 protrudes from the side surface of the base 151 away from the oil storage compartment 11. During installation, the side surface of the support 1512 away from the oil storage compartment 11 abuts against the inner wall of the base shell 152, and at this time, the inner circumferential surface of the base shell 152, the side surface of the base 151 away from the oil storage compartment 11, and the outer circumferential surface of the support 1512 away from the air inlet passage 1511 can collectively define the communication passage 153. In this way, the structure of the communication passage 153 is simple and convenient to process, and at the same time, the support 1512 can act as a reinforcing rib 1517, thereby improving the structural strength of the base 151.

[0115] According to some specific embodiments of the present application, the air inlets 1521 are multiple, and the multiple air inlets 1521 are respectively located on the two sides of the shell 1 along the width direction. In the description of the present application, the meaning of "multiple" is two or more. Referring to Figure 1 and Figure 18 , the air inlets 1521 can be two, and the two air inlets 1521 are respectively located on the two sides of the shell 1 along the width direction of the shell 1, and at this time, the two air inlets 1521 are symmetrical about the central axis of the shell 1. By arranging multiple air inlets 1521, the amount of air in the atomization compartment 13 can be further increased, so that the atomization medium can be mixed with air in a short time, and the user experience is further improved.

[0116] Figure 1 Two air inlets 1521 are shown in the above description for illustrative purposes, but it is obvious for those skilled in the art to understand that this scheme can be applied to three or more air inlets 1521 after reading the technical scheme of the present application, which also falls within the protection scope of the present application.

[0117] The support 1512 is in plurality, and the plurality of supports 1512 are respectively located on both sides of the base 151 along the width direction of the shell 1. Referring to Figure 14 , Figure 15 and Figure 16 , the support 1512 is in two, and the two supports 1512 are respectively located on both sides of the air inlet channel 1511 along the width direction of the shell 1, so that two communication channels 153 are formed in the shell 1, and the two communication channels 153 correspond to the two air inlets 1521 one by one, so that the external air quickly flows to the air inlet channel 1511. In addition, by arranging a plurality of supports 1512, the contact area of the support 1512 and the inner wall of the base shell 152 can be increased, so that the base 151 is stably installed in the base shell 152.

[0118] According to some embodiments of the present application, referring to Figure 1 , the atomization device 100 further comprises an air resistance adjusting member 4 arranged at the air inlet channel 1511. Specifically, the air resistance adjusting member 4 is located below the atomization chamber 13 and communicates with the atomization chamber 13, so that the air flows into the atomization chamber 13 after flowing through the air resistance adjusting member 4. Thus, the air resistance adjusting member 4 can be used to adjust the size of the air inlet, so as to adjust the air resistance when the user smokes the electronic cigarette. Further, the atomization device 100 with different air resistance can be arranged, and then electronic cigarettes with multiple air resistance specifications can be arranged to meet the actual needs of different users and improve the smoking experience of users.

[0119] According to some embodiments of the present application, the air resistance adjusting piece 4 is formed with a communication hole 41, the communication hole 41 communicates the air inlet 1521 and the atomization chamber 13, and the inner diameter of the communication hole 41 is d, wherein d satisfies: 0.8mm≤d≤1.5mm. When the inner diameter of the communication hole 41 is less than 0.8mm, the amount of air flowing into the atomization chamber 13 is small, the air resistance is large during the user's smoking of the electronic cigarette, which is not conducive to the normal use of the electronic cigarette; when the inner diameter of the communication hole 41 is greater than 1.5mm, the amount of air flowing into the atomization chamber 13 from the communication hole 41 is large, which increases the proportion of air in the mixed smoke in the atomization chamber 13, reduces the concentration of the smoke generated by the medium to be atomized, weakens the tobacco smell of the mixed smoke, and the air resistance is small when the user smokes the electronic cigarette, which reduces the user's smoking experience. Therefore, by making d satisfy 0.8mm≤d≤1.5mm, the normal use of the atomization device 100 can be ensured, the user's smoking effect is improved, at the same time, the air resistance adjusting piece 4 can be suitable for electronic cigarettes of different specifications, and different air resistance atomization devices 100 can be obtained by setting communication holes 41 with different inner diameters, different air resistance electronic cigarettes are prepared, the diversification of electronic cigarette products is realized, and the user can select electronic cigarettes with different air resistance specifications according to his own needs. In the present application, the inner diameter of the communication hole 41 on each air resistance adjusting piece 4 is taken as an example for description, and it can be understood that the communication hole 41 can also be set as an inner diameter adjustable communication hole 41.

[0120] According to some embodiments of the present application, as shown in Figure 1 、 Figure 3 and Figure 8 , the base 151 is provided with a conductive piece 5, the atomization core fixing piece 2 is formed with a receiving groove 22, the atomization core is arranged in the receiving groove 22, one side of the receiving groove 22 adjacent to the oil storage chamber 11 is formed with an oil storage chamber communication port 221, and the oil storage chamber 11 communicates with the atomization core through the oil storage chamber communication port 221, so that the medium to be atomized can flow to the atomization core through the oil storage chamber communication port 221, and the atomization core can atomize the medium to be atomized into atomized medium. The receiving groove 22 has an open side which is open to the atomization chamber 13, the atomization core communicates with the atomization chamber 13 through the open side, part of the atomization core and the receiving groove 22 can form the atomization chamber 13, and the atomization core and the atomization chamber 13 can communicate through the open side.

[0121] Referring to Figure 1 and Figure 3, one end of the conductive piece 5 penetrates into the accommodating groove 22 through the open side and is electrically connected with the atomizing core, and the atomizing core is abutted between the inner wall of the side of the accommodating groove 22 facing the oil storage chamber 11 and the conductive piece 5 to realize the fixation of the atomizing core. In other words, the conductive piece 5 can be abutted below the atomizing core through the base 151, and the atomizing core is abutted above the atomizing core through the inner wall of the atomizing core fixing piece 2 to form the fixation and limiting of the atomizing core, so that the movement of the atomizing core along the length direction of the shell 1 can be limited, and the stability of the position of the atomizing core is ensured.

[0122] Further, as shown in Figures 1-3 , the atomizing core sealing piece 6 is arranged between the inner wall of the side of the accommodating groove 22 adjacent to the oil storage chamber 11 and the atomizing core. In other words, the atomizing core sealing piece 6 is arranged between the end of the atomizing core away from the conductive piece 5 and the inner wall of the side of the accommodating groove 22 adjacent to the oil storage chamber communication port 221. Thus, the sealing between the accommodating groove 22 and the atomizing core can be improved, and when the medium to be atomized flows from the oil storage chamber 11 to the atomizing chamber 13, the medium to be atomized can be prevented from flowing out from the gap between the atomizing core and the atomizing core fixing piece 2.

[0123] Referring to Figures 1-3 , the atomizing core sealing piece 6 is formed with a through sealing piece communication port 61, and the oil storage chamber 11 communicates with the atomizing core through the oil storage chamber communication port 221 and the sealing piece communication port 61. The sealing piece communication port 61 can be multiple, and each oil storage chamber communication port 221 corresponds to at least one sealing piece communication port 61, and the medium to be atomized in the oil storage chamber 11 can flow to the atomizing core through the sealing piece communication port 61 after flowing through the oil storage chamber communication port 221. Thus, the sealing piece communication port 61 is formed on the atomizing core sealing piece 6 to enable the medium to be atomized to flow from the oil storage chamber 11 to the atomizing core to realize the atomization of the medium to be atomized, which facilitates the flowability of the medium to be atomized and realizes the replenishment of the medium to be atomized in the atomizing core.

[0124] In some optional embodiments, referring to Figure 9 , Figure 15 and Figure 16 and combining with Figure 1 , the base 151 is provided with at least one buckle 1513, and the atomizing core fixing piece 2 is formed with at least one buckle position 23, and the buckle 1513 and the buckle position 23 are matched to clamp the atomizing core fixing piece 2 and the base assembly 15. Thus, by arranging the buckle 1513 and the buckle position 23 matched with each other, the assembly of the atomizing core fixing piece 2 and the base 151 can be facilitated, the connection mode is simple to operate, and is conducive to the production and processing of the atomizing device 100, thereby facilitating the production and processing of the electronic cigarette and reducing the cost. In addition, by fixing the atomizing core fixing piece 2 and the base 151, the position of the atomizing core fixing piece 2 can be limited, and the atomization effect of the atomizing device 100 is effectively ensured.

[0125] Further, referring to Figure 9 ,Figure 15 and Figure 16 and in combination Figure 1 The side wall of the open side of the accommodating groove 22 is provided with at least one buckle position 23, the free end of the buckle 1513 is provided with a buckle part 1514, the buckle part 1514 abuts against the side surface of the buckle position 23 away from the base assembly 15 through the open side. Thus, the buckle part 1514 is connected with the atomization core fixing piece 2 through the open side, and by arranging the buckle part 1514 and the buckle position 23 that abut against each other, the connection between the atomization core fixing piece 2 and the base 151 is more secure, and the base 151 is not easy to fall off from the atomization core fixing piece 2, thereby ensuring the normal use of the atomization device 100 and prolonging the use time of the atomization device 100.

[0126] In some optional embodiments, as shown in Figure 9 The buckle position 23 is provided with a buckle position guide surface 231, which extends obliquely from the base assembly 15 towards the center of the shell 14 and towards the buckle 1513. For example, the buckle position guide surface 231 is located on the side of the buckle position 23 away from the buckle part 1514. During the assembly of the atomization core fixing piece 2 and the base assembly 15, the buckle part 1514 of the buckle 1513 abuts against and moves along the buckle position guide surface 231, the buckle part 1514 deforms towards the direction away from the buckle position 23, so that the buckle part 1514 passes through the communication port, and after the buckle part 1514 separates from the buckle position guide surface 231, the buckle part 1514 moves towards the direction of the buckle position 23 and abuts against the surface of the buckle position 23 facing the center of the shell 14. At this time, the buckle 1513 and the buckle position 23 are assembled in place, thereby completing the assembly of the atomization core fixing piece 2 and the base assembly 15. Thus, by arranging the buckle position guide surface 231, the installation of the buckle 1513 can be guided, which is beneficial to the buckle part 1514 of the buckle 1513 passing through the communication port along the length direction of the shell 14 and cooperating with the buckle position 23 more conveniently, thereby facilitating the assembly of the atomization core fixing piece 2 and the base assembly 15, and further improving the installation efficiency of the atomization device 100.

[0127] As Figure 14 , Figure 15 and Figure 16As shown, the buckle portion 1514 has a first buckle guide surface 1515, which extends obliquely from the direction of the base assembly 15 towards the center of the shell 14 to the direction away from the buckle site 23. During the assembly of the atomization core fixing member 2 and the base assembly 15, the first buckle guide surface 1515 of the buckle portion 1514 faces the buckle site guide surface 231 and moves along the buckle site guide surface 231, and the first buckle guide surface 1515 deforms in the direction away from the buckle site 23, so that the first buckle guide surface 1515 passes through the communication opening. After the first buckle guide surface 1515 passes through the communication opening and separates from the buckle site guide surface 231, the first buckle guide surface 1515 moves in the direction of the buckle site 23 to restore the initial state, and the buckle portion 1514 abuts against the surface of the buckle site 23 facing the center of the shell 14. At this time, the buckle 1513 and the buckle site 23 are assembled in place, thereby completing the assembly of the atomization core fixing member 2 and the base assembly 15. In this way, by providing the first buckle guide surface 1515, the buckle portion 1514 can be connected to the buckle site 23 after passing through the communication opening, thereby improving the assembly speed of the base assembly 15 and the atomization core fixing member 2. Optionally, the inclination angle of the buckle site guide surface 231 is substantially the same as the inclination angle of the first buckle guide surface 1515, so as to facilitate the assembly of the buckle 1513 and the buckle site 23.

[0128] Further, referring to Figure 14 , Figure 15 and Figure 16 , the buckle 1513 has a second buckle guide surface 1516, which is located on the side of the buckle 1513 away from the buckle portion 1514 and extends obliquely from the direction of the base assembly 15 towards the center of the shell 14 to the direction of the buckle site 23. In this way, the longitudinal section of the top of the buckle 1513 is substantially trapezoidal, which facilitates the deformation of the free end of the buckle 1513 during assembly, and the inclined second buckle guide surface 1516 has a guiding effect on the air entering the atomization chamber 13 from the outside, which can better realize the mixing of the air and the smoke atomized by the atomization core. In addition, the relatively small buckle 1513 can reduce the occupied space of the buckle 1513 in the atomization chamber 13.

[0129] In some optional embodiments, the side of the buckle 1513 away from the buckle portion 1514 is provided with at least one reinforcing rib 1517. For example, in the examples of Figure 14 , Figure 15 and Figure 16 , the second buckle guide surface 1516 is located on the side of the reinforcing rib 1517 away from the base assembly 15, the reinforcing rib 1517 extends along the length direction of the shell 14, and the reinforcing rib 1517 can be fixedly connected with the base assembly 15. In this way, the structural strength of the buckle 1513 can be improved, and the connection between the atomization core fixing member 2 and the base assembly 15 is more firm.

[0130] Further, the reinforcing ribs 1517 are multiple, and the multiple reinforcing ribs 1517 are arranged at intervals and are connected with the base assembly 15. For example, in the example shown in Figure 14 , the multiple reinforcing ribs 1517 are arranged at intervals along the thickness direction of the shell 1. Thus, by arranging the multiple reinforcing ribs 1517 as described above, the structure strength of the buckle 1513 is improved, and at the same time, the buckle 1513 has a certain deformation ability, which facilitates the assembly of the buckle 1513 and the buckle position 23, and can save the material of the buckle 1513, thereby reducing the cost. It can be understood that the number of reinforcing ribs 1517 can be set according to actual use requirements to better meet actual application.

[0131] According to some embodiments of the present application, the atomizing core fixing member 2 is formed with an air exchange groove 24, and the air exchange groove 24 and the atomizing core together define an air exchange channel. The width of the air exchange groove is W1, and the depth of the air exchange groove is H1, wherein W1 and H1 respectively satisfy: 0.25mm≤W1≤0.5mm, 0.1mm≤H1≤0.4mm. The width of the air exchange groove 24 can be the distance in the front-rear direction as shown in Figure 8 , and the depth of the air exchange groove can be the distance in the up-down direction as shown in Figure 8 . For example, W1=0.3mm, H1=0.3mm. If W1>0.5mm, it may lead to a thicker thickness of the atomizing core fixing member 2, resulting in a larger volume of the atomizing device 100, which is not conducive to miniaturization design, or if H1>0.4mm, it may lead to a deeper depth of the air exchange groove, and the bottom wall of the air exchange groove is thinner, which is prone to leakage of the atomized medium over time. If W1<0.25mm or H1<0.4mm, it may lead to a smaller width and depth of the air exchange groove, which will result in an unsatisfactory air exchange effect and increase the process difficulty of manufacturing the air exchange groove 24. Thus, by making W1 and H1 respectively satisfy: 0.25mm≤W1≤0.5mm, 0.1mm≤H1≤0.4mm, the effectiveness of the air exchange inside the shell 1 can be increased, the air exchange amount is ensured, the thin design of the atomizing device 100 is realized, the leakage of the atomized medium with a small thickness in the air exchange groove is avoided, the processing difficulty is reduced, and thus the production efficiency can be improved.

[0132] Further, as shown in Figure 8As shown, the accommodating groove 22 comprises a bottom wall and a side wall, and the side wall is connected to the outer peripheral side of the bottom wall. The air exchange groove comprises a first air exchange groove 241 and at least one second air exchange groove 242, the first air exchange groove 241 is formed on the bottom wall, and the first air exchange groove 241 has at least one first air exchange port 2411 which communicates with the oil storage compartment 11. Here, the number of first air exchange ports 2411 can be two, and the two first air exchange ports 2411 respectively communicate with the oil storage compartment 11. The second air exchange groove 242 is formed on the side wall, the second air exchange groove 242 respectively communicates with the first air exchange groove 241 and the atomization compartment 13, and the depth of the second air exchange groove 242 is greater than the depth of the first air exchange groove 241.

[0133] Therefore, the first air exchange groove 241 is formed on the bottom wall of the accommodating groove 22, the second air exchange groove 242 is formed on the side wall of the accommodating groove 22, and the first air exchange groove 241 communicates with the second air exchange groove 242, which facilitates the circulation of air between the atomization compartment 13 and the oil storage compartment 11, can realize the thinning of the atomization device 100, and increases the compactness of the structure of the accommodating groove 22. By setting the depth of the second air exchange groove 242 to be greater than the depth of the first air exchange groove 241, air can enter the air exchange groove to realize air exchange, so that the effect of air exchange is better, the flowability of the atomization medium is better, and the continuity of atomization during use of the atomization device 100 is ensured.

[0134] In some optional embodiments, the cross-sectional area of the second air exchange groove 242 gradually decreases in the direction towards the oil storage compartment 11. For example, the depth of the second air exchange groove 242 gradually decreases from the direction away from the first air exchange groove 241 to the direction adjacent to the first air exchange groove 241, and the depth of one end of the second air exchange groove 242 adjacent to the first air exchange groove 241 can be equal to the depth of the first air exchange groove 241. Therefore, the cross-sectional area of the second air exchange groove 242 gradually decreases in the direction towards the oil storage compartment 11, which can facilitate air entering the air exchange groove to increase the air intake of the air exchange groove, so that the gas circulation between the oil storage compartment 11 and the atomization compartment 13 is better.

[0135] Further, the bottom wall of the second air exchange groove 242 extends obliquely in the direction towards the oil storage compartment 11 and in the direction towards the center of the atomization core. It should be noted that the bottom wall of the second air exchange groove 242 refers to the side of the second air exchange groove 242 away from the center of the atomization core. Therefore, the bottom wall of the second air exchange groove 242 gradually inclines towards the side of the center of the atomization core in the direction towards the oil storage compartment 11, and the bottom wall can guide the air intake of the second air exchange groove 242, so that the air entering from the air intake port 1521 can smoothly enter the first air exchange groove 241 through the second air exchange groove 242, avoiding turbulence of the air between the first air exchange groove 241 and the second air exchange groove 242, and increasing the speed of air intake.

[0136] According to some embodiments of the present application, the first air exchange groove 241 extends along the circumference of the oil storage compartment communication opening 221, the first air exchange opening 2411 penetrates the side wall of the oil storage compartment communication opening 221 along the thickness direction of the shell 1, the first air exchange groove 241 comprises a first side wall and a second side wall, the first side wall is arranged away from the center of the accommodating groove 22, the second side wall is arranged adjacent to the center of the accommodating groove 22, the first air exchange opening 2411 is arranged on the second side wall, and after the atomizing core and the accommodating groove 22 are assembled, the first air exchange opening 2411 can communicate the first air exchange groove 241 and the oil storage compartment 11 to achieve air exchange. The second air exchange groove 242 is located on the side wall of the accommodating groove 22 along the width direction of the shell 1, and the second air exchange groove 242 can extend along the length direction of the shell 1 to communicate the first air exchange groove 241 and the atomizing compartment 13. In this way, the first air exchange groove 241 extends along the circumference of the oil storage compartment communication opening 221, the second air exchange groove 242 is located on the side wall of the accommodating groove 22 along the width direction of the shell 1, and the thinning treatment of the accommodating groove 22 can be realized while avoiding the leakage of the medium to be atomized from the air exchange groove.

[0137] According to some specific embodiments of the present application, in combination with Figure 8 , the air exchange groove further comprises at least one air exchange communication section 243, the air exchange communication section 243 is formed on the bottom wall, one end of the air exchange communication section 243 communicates with the first air exchange groove 241, the other end of the air exchange communication section 243 extends into the second air exchange groove 242 and communicates with the second air exchange groove 242, and the edge of the air exchange communication section 243 is connected with the inner wall of the second air exchange groove 242. In this way, the air exchange passage is arranged between the first air exchange groove 241 and the second air exchange groove 242 to communicate the first air exchange groove 241 and the second air exchange groove 242, air can flow between the atomizing compartment 13 and the oil storage compartment 11 through the first air exchange groove 241, the air exchange passage and the second air exchange groove 242, so that the user can relatively easily smoke when inhaling the smoke at the inhalation port 141, the comfort of smoking is increased, and the medium to be atomized in the oil storage compartment 11 can flow out of the oil storage compartment 11 for atomization.

[0138] According to some embodiments of the present application, as Figures 1-3 shown, the base seal 7 is arranged between the atomizing core fixing member 2 and the base 151. In this way, the base seal 7 fills the gap between the atomizing core assembly and the base 151, better seals the gap, reduces the probability of the smoke in the atomizing compartment 13 flowing out of the gap between the atomizing core assembly and the base 151, effectively prevents the leakage of the condensed smoke, improves the utilization rate of the smoke in the atomizing compartment 13, and thus improves the effective utilization rate of the medium to be atomized.

[0139] Further, please refer to Figure 12The base seal 7 comprises a first base seal segment 71 and a second base seal segment 72. The first base seal segment 71 is arranged between the atomization core fixing member 2 and the base assembly 15. The second base seal segment 72 is connected to the first base seal segment 71 and is arranged between the outer circumferential surface of the base assembly 15 and the inner circumferential surface of the shell 14.

[0140] For example, in the example shown in Figures 1-2 and Figures 12-13 , the top surface of the first base seal segment 71 abuts against the bottom surface of the atomization core fixing member 2, the bottom surface of the first base seal segment 71 abuts against the top surface of the base 151, the outer circumferential surface of the second base seal segment 72 abuts against the inner circumferential surface of the shell 14, and the inner circumferential surface of the second base seal segment 72 abuts against the outer circumferential surface of the base 151. In this way, the first base seal segment 71 can be used to seal the gap between the bottom of the atomization core fixing member 2 and the top of the base 151, and the second base seal segment 72 can seal the gap between the inner wall of the shell 14 and the circumference of the base 151. In this way, the sealing performance between the atomization core fixing member 2, the shell 14 and the base 151 is further improved, which can better reduce the leakage of smoke in the atomization cartridge 13, and at the same time can make the assembly between the base 151 and the atomization core fixing member 2 and the shell 14 more secure.

[0141] According to some embodiments of the present application, as shown in Figures 7-9 , at least one oil storage groove 25 is formed on the atomization core fixing member 2. For example, the oil storage groove 25 is used to store part of the liquid medium generated in the atomization core fixing member 2. When the high-temperature smoke generated by atomization meets the low-temperature air entering through the air inlet 1521, part of the high-temperature smoke will condense to form liquid medium attached to the surface of the oil storage groove 25, and the oil storage groove 25 can form a collection of this part of the liquid. The width of the oil storage groove 25 is W2, and the depth of the oil storage groove 25 is H2, wherein W2 and H2 respectively satisfy: 0.25mm≤W2≤0.5mm, 0.1mm≤H2≤0.4mm. Optionally, W2=0.35mm, H2=0.25mm. But not limited to this.

[0142] Further, as shown in Figure 7 , from the groove bottom of the oil storage groove 25 to the direction of the groove opening of the oil storage groove 25, the width of the oil storage groove 25 gradually increases. The cross-sectional shape of the oil storage groove 25 can be trapezoidal, and the groove bottom of the oil storage groove 25, i.e. the side of the oil storage groove 25 adjacent to the center of the atomization core fixing member 2, is smaller than the side of the oil storage groove 25 away from the center of the atomization core fixing member 2. In this way, the width of the groove opening of the oil storage groove 25 is greater than the width of the groove bottom, which can facilitate the attachment of the condensed liquid medium on the surface of the oil storage groove 25, and increase the contact area between the oil storage groove 25 and the liquid medium.

[0143] Further, referring to Figure 7The oil storage groove 25 is multiple, and the multiple oil storage groove 25 includes at least one first oil storage groove 251 and at least one second oil storage groove 252. The first oil storage groove 251 extends along the length direction of the shell 1, and the second oil storage groove 252 extends along the width direction of the shell 1. In this way, the oil storage groove 25 includes multiple first oil storage grooves 251 extending along the length direction and multiple second oil storage grooves 252 extending along the width direction, so that the contact between the oil storage groove 25 and the condensed liquid medium can be sufficiently increased, and the oil storage capacity of the oil storage groove 25 can be increased.

[0144] According to some embodiments of the present application, as shown in Figure 7 The outer surface of the atomizing core fixing member 2 is provided with multiple ribs, and the multiple ribs include multiple first ribs 26 and multiple second ribs 27. The multiple first ribs 26 are arranged at intervals along the width direction of the shell 1 and extend along the length direction of the shell 1, and the first oil storage groove 251 is defined between two adjacent first ribs 26. The multiple second ribs 27 are arranged at intervals along the length direction of the shell 1 and extend along the width direction of the shell 1, and the second oil storage groove 252 is defined between at least two adjacent second ribs 27. In this way, the multiple first oil storage grooves 251 and the multiple second oil storage grooves 252 can be defined at intervals by the multiple first ribs 26 and the multiple second ribs 27, respectively, so that the structural strength of the atomizing core fixing member 2 can be increased, the condensed liquid medium can be conveniently stored, and the storage capacity of the liquid medium can be increased.

[0145] Further, at least a part of the two adjacent second ribs 27 overlaps in the length direction of the shell 1. It can be understood that the two adjacent second ribs 27 can extend along the width direction of the shell 1, and the orthographic projection of the two adjacent second ribs 27 overlaps at least partially in the length direction of the shell 1. In this way, at least a part of the two second ribs 27 overlaps in the length direction of the shell 1, so that the storage capacity of the condensed liquid medium can be increased, for example, when the liquid medium falls along the length direction of the shell 1, the second ribs 27 can increase the contact area with the liquid medium, so that the liquid medium can be conveniently stored, and meanwhile, the space on the outer surface of the atomizing core fixing member 2 can be fully utilized, so that the utilization of the space on the outer surface of the atomizing core fixing member 2 can be improved.

[0146] According to some embodiments of the present application, in combination with Figure 7At least one side surface of the atomization core fixing member 2 in the thickness direction of the shell 1 is provided with an atomization chamber communication port 28 and a receiving groove 29. The atomization chamber communication port 28 penetrates the side wall of the atomization core fixing member 2. The receiving groove 29 is located on the side of the atomization chamber communication port 28 adjacent to the oil storage chamber 11 and communicates with the atomization chamber communication port 28. That is, the receiving groove 29 can be arranged on the surface of the side of the atomization core fixing member 2 where the plurality of ribs are formed. The plurality of first ribs 26 and the plurality of second ribs 27 are arranged in the receiving groove 29. The receiving groove 29 is provided with a blocking rib 291. The blocking rib 291 is connected to the side edge of the atomization chamber communication port 28 adjacent to the oil storage chamber 11 (the upper edge of the atomization chamber communication port 28). One end of the blocking rib 291 is connected to the side wall of the receiving groove 29 in the width direction of the shell 1. The other end of the blocking rib 291 is spaced apart from the other side wall of the receiving groove 29 in the width direction of the shell 1.

[0147] In the width direction of the shell 1, the side edge of the atomization chamber communication port 28 away from the first rib 26 is the edge of the receiving groove 29 away from the first rib 26. The one end of the blocking rib 291 is connected to the edge. The other end of the blocking rib 291 extends in the width direction of the shell 1 and is arranged spaced apart from the edge opposite to the edge in the width direction of the shell 1.

[0148] Therefore, the first rib 26, the second rib 27, and the blocking rib 291 are arranged in the receiving groove 29. The arrangement of the ribs and the blocking rib 291 is facilitated. The ribs and the blocking rib 291 do not excessively protrude from the outer surface of the atomization core fixing member 2 in the thickness direction of the shell 1. The space between the atomization core fixing member 2 and the shell 1 is increased. The depth of the first oil storage groove 251 and the second oil storage groove 252 and the communication between the atomization chamber 13 and the receiving groove 29 are ensured. The storage capacity of the liquid medium formed by the condensation of part of the smoke due to the meeting of low-temperature air and high-temperature smoke during the atomization process is increased. The blocking rib 291 can improve the structural strength of the receiving groove 29. The liquid medium in the first oil storage groove 251 and the second oil storage groove 252 can be prevented from flowing from the atomization chamber communication port 28 to the atomization chamber 13. The smoke available for smoking is more healthy.

[0149] Further, as shown in Figure 7 The receiving groove 29 is provided with a receiving groove communication port 292. The receiving groove communication port 292 penetrates the side wall of the atomization chamber communication port 28. The receiving groove communication port 292 is located below the blocking rib 291. The receiving groove communication port 292 communicates the receiving groove 29 and the atomization chamber communication port 28. Part of the smoke in the atomization chamber 13 can enter the receiving groove 29 along the receiving groove communication port 292 and condense in the receiving groove 29. Therefore, the arrangement of the receiving groove communication port 292 facilitates the entry of part of the smoke into the receiving groove 29. The liquid medium formed by the condensation of part of the smoke in the receiving groove 29 is attached to or stored in the oil storage groove 25. The oil leakage of the atomization device 100 is avoided.

[0150] According to some embodiments of the present application, asFigures 7-9 As shown in FIG. 1, the atomization guide channels 21 are multiple, one end of each atomization guide channel 21 is communicated with the atomization chamber 13, the other end of each atomization guide channel 21 is communicated with the air passage 12, and the other ends of the multiple atomization guide channels 21 and the air passage 12 are provided with the partition plate 8, which is used to separate the other ends of the multiple atomization guide channels 21 and guide the airflow flowing through the multiple atomization guide channels 21 to the air passage 12.

[0151] Referring to Figures 7-9 , the atomization guide channels 21 can be two, the two atomization guide channels 21 are respectively formed at the two ends of the length direction of the atomization core fixing member 2, and the partition plate 8 is arranged between one end of the two atomization guide channels 21 adjacent to the air passage 12 and the air passage 12. When the atomization device 100 works, the atomization medium in the atomization chamber 13 can flow to the partition plate 8 through the two atomization guide channels 21, at this time, the partition plate 8 can divide the two atomization media flowing to the partition plate 8 into multiple atomization media, so that the atomization medium can avoid forming turbulence at the connection between the atomization core fixing member 2 and the air passage 12, so that the atomization medium can flow smoothly to the air passage 12, thereby reducing the resistance when the user smokes, and improving the user experience.

[0152] Further, the atomization core fixing member 2 is formed with an atomization communication channel 30, the atomization communication channel 30 is communicated between the other ends of the multiple atomization guide channels 21 and the air passage 12, and the partition plate 8 is arranged at the atomization communication channel 30. As shown in Figure 7 and Figure 8 , the atomization communication channel 30 is formed at one end of the atomization core fixing member 2 adjacent to the air passage 12, one end of the atomization communication channel 30 is communicated with the air passage 12, and the other end of the atomization communication channel 30 is communicated with the atomization guide channel 21. The shape of the partition plate 8 can be an isosceles triangle, both ends of the long side of the partition plate 8 are connected with the inner wall of the atomization communication channel 30, and the partition plate 8 extends in the direction towards the atomization chamber 13. Since the atomization medium is prone to form turbulence at the atomization communication channel 30, by arranging the partition plate 8 at the atomization communication channel 30, the atomization medium in the atomization communication channel 30 can be dispersed, so that the atomization medium can avoid forming turbulence in the atomization communication channel 30, to ensure the smoothness when the user smokes.

[0153] Further, as shown in Figures 7-9 , the air passage 12 extends along the length direction of the outer shell 1, the atomization communication channel 30 includes a first communication channel segment 301 and a second communication channel segment 302 connected in sequence along the length direction of the outer shell 1 towards the direction away from the air passage 12, one end of the air passage 12 is fitted in the first communication channel segment 301, and the partition plate 8 is arranged in the second communication channel segment 302.

[0154] For example, in Figures 7-9In the example, the shape of the accommodating groove 22 is adapted to the shape of the atomizing core, so as to firmly mount the atomizing core on the atomizing core fixing member 2. Each atomizing guide channel 21 is generally L-shaped, which increases the length of the atomizing guide channel 21, thereby increasing the flow path of the atomizing medium, so as to enable the atomizing medium to be fully mixed with air. When the atomizing device 100 is in operation, the atomizing medium atomized by the atomizing core can flow to the second communication channel segment 302 through the first guide channel segment and the second guide channel segment, and the mixture of the atomizing medium in the second communication channel segment 302 flows to the first communication channel segment 301 through the partition 8, and then flows to the oral cavity of the user through the first communication channel segment 301 and the air passage 12 from the suction port 141.

[0155] According to some embodiments of the present application, the atomizing device 100 further comprises an atomizing core fixing seal 9 arranged on the atomizing core fixing member 2, and the atomizing core fixing seal 9 is at least partially located between the atomizing core fixing member 2 and the inner wall of the shell 1 and between the outer peripheral surface of the air passage 12 and the inner wall of the first communication channel segment 301. Referring to Figure 5 and in combination with Figure 1 and Figure 2 , the atomizing core fixing seal 9 comprises a first sealing segment 91, a second sealing segment 92 and a third sealing segment 93 connected to each other, the first sealing segment 91 is arranged on the side of the atomizing core fixing member 2 adjacent to the oil storage compartment 11, the second sealing segment is located between the atomizing core fixing member 2 and the inner wall of the shell 1, and the third sealing segment 93 is located between the stepped portion of the air passage 12 and the inner wall of the first communication channel segment 301, so that the atomizing core fixing member 2 is in interference fit with the inner wall of the shell 1, and the air passage 12 is in interference fit with the inner wall of the first communication channel segment 301, thereby avoiding the leakage of the atomizing medium in the oil storage compartment 11 from the gap between the inner wall of the shell 1 and the atomizing core fixing member 2, and avoiding the leakage of the atomizing medium in the oil storage compartment 11 from the gap between the inner wall of the air passage 12 and the first communication channel segment 301.
