Description

Technical Field

[0001] This application relates to the field of atomization equipment technology, specifically to an atomization device. Background Technology

[0002] In atomizing devices, especially in e-cigarettes, when there is little e-liquid in the e-cigarette tank, particularly in high-altitude areas and high / low temperature environments, the volume of air inside the tank will be larger. Due to the increased thermal expansion coefficient of the gas, sudden temperature changes will severely affect the pressure inside the tank. When the pressure difference between the inside and outside exceeds the oil-locking capacity of the product's wicking cotton or integrated cotton, it will cause the e-cigarette to leak.

[0003] In summary, how to solve the leakage problem caused by low oil level in the oil tank is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, this application provides an atomizing device that at least solves the problem of e-cigarette leakage when there is a small amount of e-liquid in the oil tank.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] An atomizing device, comprising:

[0007] Oil cup;

[0008] The oil guiding assembly has a first through hole for guiding oil to the heating element of the atomizing device;

[0009] The first sealing element, together with the oil cup, forms an oil storage cavity. The first sealing element is sleeved on the outside of the oil guiding assembly. The first sealing element has a first capillary oil guiding channel and a second capillary oil guiding channel that are both connected to the first through hole.

[0010] When the atomizing device is in the upright position, the inlet end of the first capillary oil guiding channel is located above the first through hole or flush with the first through hole, and the inlet end of the second capillary oil guiding channel is located below the first through hole.

[0011] Optional,

[0012] The first capillary oil guiding channel is a groove formed on the side wall of the first seal near the oil guiding assembly; and / or,

[0013] The second capillary oil channel is a groove formed on the side wall of the first seal near the oil guiding assembly.

[0014] Optionally, a strip-shaped groove is formed on the side wall of the first seal near the oil guiding assembly, which is arranged along the axial direction of the first seal. The first capillary oil guiding channel and the second capillary oil guiding channel are different parts of the strip-shaped groove.

[0015] Optionally, an annular oil guiding channel is further formed on the side wall of the first seal near the oil guiding assembly, and multiple first through holes are formed in the circumferential direction of the oil guiding assembly, and the annular oil guiding channel is connected to all the first through holes.

[0016] Optionally, the height of the second capillary oil guiding channel and the radius of the second capillary oil guiding channel satisfy the following relationship:

[0017]

[0018] Where: h is the height of the second capillary wicking channel, σ is the surface tension of the e-liquid, θ is the contact angle between the e-liquid and the surface of the second capillary wicking channel, ρ is the density of the e-liquid, g is the acceleration due to gravity, and r is the radius of the second capillary wicking channel.

[0019] Optionally, the oil guiding assembly includes:

[0020] The housing has the first through hole;

[0021] The oil-absorbing component has a ring-shaped structure and is located inside the housing;

[0022] A sleeve is provided inside the oil suction component and has a second through hole;

[0023] An oil guide is disposed inside the sleeve and communicates with the oil suction component through the second through hole. The heating element is located inside the oil guide.

[0024] Optionally, in the oil guiding direction of the oil suction member, the projection of the first through hole is located within the second through hole.

[0025] Optionally, it includes a suction nozzle detachably connected to the oil cup, wherein the suction nozzle is provided with an air guide channel that communicates with the inner cavity of the sleeve.

[0026] Optionally, a second seal is also included, located on the side of the first seal away from the nozzle of the atomizing device, and the second seal, the first seal, the housing, and the oil cup together form the oil storage chamber.

[0027] Optionally, the inlet end of the first capillary oil guiding channel is located at the end of the first seal away from the second seal, and at the end of the first seal close to the housing; the inlet end of the second capillary oil guiding channel is located at the end of the first seal close to the second seal.

[0028] Optionally, the diameter r of the second capillary oil channel satisfies: 0.2mm≤r≤0.4mm.

[0029] The atomizing device provided in this application comprises a first sealing element and an oil cup forming an oil storage chamber. A second capillary oil guiding channel, communicating with a first through hole, is provided within the first sealing element. When the atomizing device is in the upright position, the inlet end of the second capillary oil guiding channel is located below the first through hole. That is, when the atomizing device is in the upright position and the user is using the atomizing device, if there is little e-liquid in the oil storage chamber, the e-liquid flows through the second capillary oil guiding channel to the first through hole of the oil guiding assembly. Since the inlet end of the second capillary oil guiding channel is located below the first through hole, the e-liquid needs to overcome gravity and move upward to reach the first through hole during the flow of e-liquid through the second capillary channel to the oil guiding assembly. This flow method increases the outflow resistance of e-liquid when there is little e-liquid in the oil storage chamber, thereby reducing or even preventing e-liquid leakage from the oil storage chamber when the pressure inside the oil storage chamber is low, thus improving the user experience of the electronic cigarette.

[0030] Furthermore, a first capillary wicking channel communicating with the first through hole is provided within the first seal. The inlet end of the first capillary wicking channel is located above or flush with the first through hole. When the e-liquid level in the reservoir is higher than the inlet end of the first capillary wicking channel, the e-liquid flows horizontally or downward through the first through hole into the wicking assembly. Compared to the upward flow of e-liquid through the second capillary wicking channel, the e-liquid experiences less resistance when flowing within the first capillary wicking channel. With this design, when the e-liquid level in the reservoir is high, the air volume within the reservoir is small, resulting in a higher negative pressure. This allows the e-liquid to enter the first through hole of the wicking assembly through the less resistant first capillary wicking channel, ensuring a sufficient supply of e-liquid to the atomizer and providing the user with a good vaping experience. Here, by setting up capillary channels for the e-liquid to flow from the storage chamber to the e-liquid guide assembly, the flow efficiency of the e-liquid can be guaranteed when there is a lot of e-liquid in the storage chamber, and leakage of e-liquid in the storage chamber can be avoided when there is a little e-liquid in the storage chamber.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] like Figures 1 to 4As shown, this application provides an atomizing device for atomizing a medium into an aerosol, which is then inhaled by a user to achieve the purpose of smoking. The atomizing medium can be e-liquid. The atomizing device mainly includes an oil cup 1, an oil guiding assembly 2, and a first sealing member 3. The oil guiding assembly 2 has a first through hole 211 for guiding oil to the heating element 4 of the atomizing device. The oil guiding assembly 2 guides the e-liquid in the oil storage chamber 7 to the location of the heating element 4, which atomizes the e-liquid into an aerosol. The first sealing member 3 and the oil cup 1 form an oil storage chamber 7. The first sealing member 3 is sleeved on the outside of the oil guiding assembly 2. The first sealing member 3 has a first capillary oil guiding channel 31 and a second capillary oil guiding channel 32, both of which communicate with the first through hole 211. Here, both the first capillary oil guiding channel 31 and the second capillary oil guiding channel 32... The first through hole 211 is used to guide the e-liquid in the oil storage chamber 7 to the oil guiding assembly 2, so as to supply the e-liquid in the oil storage chamber 7 to the heating element 4 for heating; that is, the e-liquid in the oil storage chamber 7 can be guided to the first through hole 211 of the oil guiding assembly 2 through the first capillary oil guiding channel 31, and the e-liquid in the oil storage chamber 7 can also be guided to the first through hole 211 of the oil guiding assembly 2 through the second capillary oil guiding channel 32. Both the first capillary oil guiding channel 31 and the second capillary oil guiding channel 32 are used to export the e-liquid in the oil storage chamber 7; wherein, when the atomizing device is in the upright state, the inlet end of the first capillary oil guiding channel 31 ( Figure 3 The area shown in C is located above the first through hole 211. When the e-liquid in the storage cavity flows to the first through hole 211 through the first capillary wicking channel 31, the e-liquid's flow speed within the first capillary wicking channel 31 is increased due to the starting point being higher than the ending point, caused by the e-liquid's own gravity. Since the inlet end of the first capillary wicking channel 31 is flush with the first through hole 211, the e-liquid in the storage cavity does not need to overcome its own gravity to flow to the first through hole 211, thus improving the e-liquid's flow efficiency. Therefore, the first capillary wicking channel 31 can improve the e-liquid's flow efficiency. The inlet end of the second capillary wicking channel 32 ( Figure 3 The area shown in D is located below the first through hole 211. This means that regardless of how the second capillary wicking channel 32 is configured, the e-liquid must overcome its own gravity to reach the location of the first through hole 211 in the wicking assembly 2 during its flow within the second capillary wicking channel 32. Thus, when the e-liquid level in the reservoir 7 is low and below the inlet of the first capillary wicking channel 31, the e-liquid needs to flow through the second capillary wicking channel 32 to reach the wicking assembly 2. The e-liquid flowing within the second capillary wicking channel 32 must overcome its own gravity to reach the first through hole 211, thereby preventing leakage when the e-liquid level in the reservoir 7 is low.

[0042] Specifically, when the e-liquid in the reservoir 7 of the atomizer is low, the e-liquid can only flow through the first through-hole 211 of the wicking assembly 2 via the second capillary wicking channel 32. When the user is not using the atomizer, the following conditions must be met: the pressure of the e-liquid due to the pressure difference inside and outside the reservoir 7 + the capillary force of the second capillary wicking channel 32 - the gravity that the e-liquid needs to overcome to rise ≤ the capillary force of the suction component 22 on the e-liquid (i.e., the e-liquid locking capacity of the suction component 22). This ensures that the force on the e-liquid is within the above relationship, so that the e-liquid remains within the suction component 22, thereby preventing leakage from the atomizer. When the user is using the atomizer, the following conditions must be met: the pressure of the e-liquid due to the pressure difference inside and outside the reservoir 7 + the capillary force of the second capillary wicking channel 32 ≥ the gravity that the e-liquid needs to overcome to rise. This ensures that the force on the e-liquid is within the above relationship, so that the e-liquid continuously enters the suction component 22, ensuring normal vaping by the user.

[0043] It should be noted that the shapes of the first capillary wicking channel 31 and the second capillary wicking channel 32 are not limited here; both channels can be straight or curved. Specifically, regarding the second capillary wicking channel 32, setting it as a curved channel increases the flow distance of the e-liquid, further enhancing the flow resistance and thus preventing leakage when there is insufficient e-liquid in the reservoir 7.

[0044] It should also be noted that the misting device is in the upright position. Figure 2 and Figure 3 The state of the atomizing device, the upright position of the atomizing device, is usually the state in which the user holds the e-cigarette when inhaling it.

[0045] In the atomizing device described above, the first sealing member 3 and the oil cup 1 form an oil storage chamber 7. A second capillary oil guiding channel 32, which communicates with the first through hole 211, is provided inside the first sealing member 3. When the atomizing device is in the upright position, the inlet end of the second capillary oil guiding channel 32 is located below the first through hole 211. That is to say, when the atomizing device is in the upright position and the user is using the atomizing device, when there is little e-liquid in the oil storage chamber 7, the e-liquid flows through the second capillary oil guiding channel 32 to the first through hole 211 of the oil guiding assembly 2. Since the inlet end of the second capillary oil guiding channel 32 is located below the first through hole 211, the e-liquid needs to overcome gravity and move upward to reach the first through hole 211 during the process of flowing through the second capillary channel to the oil guiding assembly 2. This flow method can increase the outflow resistance of e-liquid when there is little e-liquid in the oil storage chamber 7, thereby reducing or even preventing e-liquid from leaking out of the oil storage chamber 7 when the pressure in the oil storage chamber 7 is low, thus improving the user experience of the e-cigarette. Furthermore, a first capillary wicking channel 31 communicating with the first through hole 211 is provided within the first sealing element 3. The inlet end of the first capillary wicking channel 31 is located above or flush with the first through hole 211. When the e-liquid level in the oil storage chamber 7 is higher than the inlet end of the first capillary wicking channel 31, the e-liquid flows horizontally or downward through the first through hole 211 into the wicking assembly 2 via the inlet end of the first capillary wicking channel 31. Compared to the method where the e-liquid flows upward through the second capillary wicking channel 32 into the wicking assembly 2, the resistance is lower when the e-liquid flows within the first capillary wicking channel 31. With this configuration, when the e-liquid level in the oil storage chamber 7 is high, the air volume in the oil storage chamber 7 is small, and the negative pressure in the oil storage chamber 7 is large. The e-liquid will enter the first through hole 211 of the wicking assembly 2 through the first capillary wicking channel 31, which has lower flow resistance, thereby ensuring the e-liquid supply to the atomizing device and ensuring a good vaping experience for the user. Here, by setting up capillary channels for the flow of the above two types of e-liquid from the oil storage chamber 7 to the oil guiding assembly 2, it is possible to ensure the flow efficiency of the e-liquid when there is a lot of e-liquid in the oil storage chamber 7, and to prevent the e-liquid from leaking out of the oil storage chamber 7 when there is a little e-liquid in the oil storage chamber 7.

[0046] In some embodiments, please refer to Figures 1 to 3 The first capillary oil guiding channel 31 is a groove formed on the side wall of the first seal 3 near the oil guiding assembly 2; and / or, the second capillary oil guiding channel 32 is a groove formed on the side wall of the first seal 3 near the oil guiding assembly 2. Normally, the first seal 3 is a silicone structure. Here, by setting the first capillary oil guiding channel 31 and / or the second capillary oil guiding channel 32 as grooves formed on the side wall of the first seal 3 near the oil guiding assembly 2, the grooving efficiency on the first seal 3 can be improved, and the flow efficiency of e-liquid within the capillary channels can be enhanced.

[0047] In addition, the first capillary oil guiding channel 31 and the second capillary oil guiding channel 32 can also be opened in other locations of the first seal 3, such as inside the first seal 3 and the second seal 6.

[0048] In some embodiments, please refer to Figures 1 to 3 A strip-shaped groove is formed on the side wall of the first sealing member 3 near the oil guiding assembly 2. The first capillary oil guiding channel 31 and the second capillary oil guiding channel 32 are different parts of the strip-shaped groove. That is, the first capillary oil guiding channel 31 and the second capillary oil guiding channel 32 are connected and are two parts of the strip-shaped groove. Here, forming a through strip-shaped groove on the first sealing member 3 directly forms the first capillary oil guiding channel 31 and the second capillary oil guiding channel 32. Compared with forming two separate first capillary oil guiding channels 31 and the second capillary oil guiding channel 32, this arrangement can reduce the number of slots on the first sealing member 3, thereby improving the slotting efficiency on the first sealing member 3. Furthermore, reducing the number of slots can also improve the structural stability of the first sealing member 3. In addition, connecting the first capillary oil guiding channel 31 and the second capillary oil guiding channel 32 can especially improve the flow efficiency of e-liquid in the first capillary oil guiding channel 31, so as to ensure the supply of e-liquid and thus improve the user's smoking experience.

[0049] Of course, the first capillary oil guiding channel 31 and the second capillary oil guiding channel 32 may not be connected, that is, they are two separate channels.

[0050] Furthermore, based on the above embodiment, the strip groove is arranged along the axial direction of the first sealing member 3. It should be noted that the axial direction of the first sealing member 3 is... Figure 2 The direction indicated by the double-headed arrow Z. With this configuration, whether the e-liquid moves along the first capillary wicking channel 31 or the second capillary wicking channel 32, the movement distance of the e-liquid within the first capillary wicking channel 31 can be reduced, thereby reducing the flow resistance of the e-liquid and increasing the flow rate of the e-liquid within the channel; furthermore, by setting the strip groove along the axial direction, the convenience of opening the strip groove on the first seal 3 can be improved, thereby improving the efficiency of grooving.

[0051] Of course, the groove can also be set in other ways, for example, there is an angle between the groove and the axial direction of the first seal 3.

[0052] In some embodiments, please refer to Figures 1 to 4An annular oil guiding channel 33 is also formed on the side wall of the first sealing member 3 near the oil guiding assembly 2. Multiple first through holes 211 are formed in the circumference of the oil guiding assembly 2, and the annular oil guiding channel 33 is connected to all the first through holes 211. In this way, when the e-liquid flows to the first through hole 211 through the first capillary oil guiding channel 31 or the second capillary oil guiding channel 32, the annular oil guiding channel 33 guides the e-liquid to the annular oil guiding channel 33. The e-liquid then flows within the annular oil guiding channel 33 and then flows to different first through holes 211. By setting the annular oil guiding channel 33, more flow space can be provided for the e-liquid, which can improve the efficiency of the e-liquid flowing to the first through hole 211. Moreover, since multiple first through holes 211 are provided, when some of the first through holes 211 are blocked during the process of e-liquid flowing to the first through holes 211 through the above structure, the annular oil guiding channel 33 can guide the e-liquid to other first through holes 211 due to the provision of the annular oil guiding channel 33, without affecting the flow efficiency of the e-liquid, so as to ensure that the e-liquid can flow to the heating element 4 continuously.

[0053] In some embodiments, please refer to Figures 1 to 3 The height and radius of the second capillary oil guiding channel 32 satisfy the following relationship:

[0054]

[0055] Where: h is the height of the second capillary wicking channel 32, σ is the surface tension of the e-liquid, θ is the contact angle between the e-liquid and the surface of the second capillary wicking channel 32, ρ is the density of the e-liquid, g is the acceleration due to gravity, and r is the radius of the second capillary wicking channel 32.

[0056] Specifically, once the e-liquid in the oil storage chamber 7 and the first sealing element 3 for opening the second capillary oil guiding channel 32 are selected and determined, the surface tension of the e-liquid, the contact angle between the e-liquid and the surface of the second capillary oil guiding channel 32, the density of the e-liquid, and the gravitational acceleration are all constant values. Therefore, the height and radius of the second capillary oil guiding channel 32 are inversely proportional. That is, if the height of the second capillary oil guiding channel 32 is larger, the radius of the second capillary oil guiding channel 32 is smaller, and if the height of the second capillary oil guiding channel 32 is smaller, the radius of the second capillary oil guiding channel 32 is larger. This ensures that the second capillary oil guiding channel 32 can prevent leakage when there is less e-liquid in the oil storage chamber 7. Here, by satisfying the above-mentioned relationship between the height and radius of the second capillary wicking channel 32, the relationship between the height and radius of the second capillary wicking channel 32 can be limited according to parameters such as the surface tension of the e-liquid, the contact angle between the e-liquid and the surface of the second capillary wicking channel 32, the density of the e-liquid, and the acceleration due to gravity. This ensures that when there is little e-liquid in the e-liquid reservoir 7, leakage from the e-liquid reservoir 7 is prevented when the user is not using the atomizing device, and the supply of e-liquid is guaranteed when the user is using the atomizing device.

[0057] In some embodiments, please refer to Figures 1 to 3The oil guiding assembly 2 includes a housing 21, an oil suction member 22, a sleeve 23, and an oil guiding member 24. The housing 21 has a first through hole 211; the oil suction member 22 has an annular structure and is located inside the housing 21; the sleeve 23 is located inside the oil suction member 22 and has a second through hole 231; the oil guiding member 24 is located inside the sleeve 23 and is connected to the oil suction member 22 through the second through hole 231; the heating element 4 is located inside the oil guiding member 24. Specifically, when the user uses the atomizing device, the e-liquid is guided through the first capillary wicking channel 31 or the second capillary wicking channel 32 to the location of the first through hole 211 in the housing 21. Then, the e-liquid flows into the suction member 22 through the first through hole 211. The e-liquid gradually diffuses and flows within the suction member 22 to the location of the second through hole 231. The e-liquid flows into the wicking member 24 through the second through hole 231. The heating element 4 is located inside the wicking member 24. The heating element 4 heats the e-liquid in the wicking member 24 to atomize the e-liquid into an aerosol. The user inhales into the mouthpiece 5 of the atomizing device, creating a negative pressure at the location of the mouthpiece 5. As the gas flows through the location of the heating element, it carries the aerosol and is inhaled by the user. Since the first seal 3, which is made of silicone, is sleeved around the outer periphery of the housing 21, the housing 21 can provide support for the first seal 3 and provide an installation position for the oil-absorbing component 22, thereby improving the stability of the structure. The sleeve 23 is disposed between the oil-absorbing component 22 and the oil-guiding component 24 to separate them and provide support, thus preventing deformation of the oil-absorbing component 22 and the oil-guiding component 24 and improving the stability of their structures. By arranging the oil-guiding assembly 2 as described above, the structure of the oil-guiding assembly 2 becomes compact, improving the overall structural stability of the oil-guiding assembly 2.

[0058] In some embodiments, please refer to Figures 1 to 3 In the oil-guiding direction of the suction component 22, the projection of the first through hole 211 is located within the second through hole 231. That is, the size of the second through hole 231 is larger than the size of the first through hole 211, and the second through hole 231 surrounds the projection of the first through hole 211 along the oil-guiding direction of the suction component 22. This arrangement allows e-liquid entering the suction component 22 through the first through hole 211 to flow quickly into the second through hole 231, ensuring efficient e-liquid flow within the oil-guiding assembly 2 and improving the smoothness of e-liquid flow within the oil-guiding assembly 2, thereby increasing the e-liquid supply when the atomizing device is in operation.

[0059] For example, the oil guiding direction of the oil-absorbing member 22 is as follows: Figure 2 The direction indicated by the middle arrow E is the flow direction of the e-liquid within the suction unit 22.

[0060] Of course, in the oil guiding direction of the oil suction member 22, the projection of the first through hole 211 can also be located outside the second through hole 231, or the projection of the first through hole 211 can also overlap with the second through hole 231.

[0061] In some embodiments, please refer to Figures 1 to 3 The atomizing device includes a mouthpiece 5 detachably connected to the oil cup 1. An airflow channel 51 is provided inside the mouthpiece 5, and the airflow channel 51 communicates with the inner cavity of the sleeve 23. Specifically, when the user uses the atomizing device, the e-liquid in the oil storage chamber 7 flows through the first capillary oilflow channel 31 or the second capillary oilflow channel 32 to the first through hole 211, until the e-liquid is guided to the location of the oil guide component 24. The heating element 4 located in the oil guide component 24 heats the e-liquid within the oil guide component 24 and atomizes the e-liquid into an aerosol. Simultaneously, the user inhales into the mouthpiece 5, creating a negative pressure at the mouthpiece 5 location. Gas from outside the atomizing device flows into the air passage of the oil storage chamber. When the gas flows past the location of the heating element 4, the gas carries the aerosol along the airflow channel 51 to the location of the mouthpiece 5, and is then inhaled into the user's mouth, allowing the user to complete the inhalation of the aerosol. Here, by connecting the air guide channel 51 to the sleeve 23, the inner cavity of the sleeve 23 also serves as an air passage. This arrangement makes the atomizing device compact and the air passage layout within the atomizing device reasonable.

[0062] In addition, the oil cup 1 can be integrally formed with the mouthpiece 5, which can improve the overall stability of the atomizing device.

[0063] In some embodiments, please refer to Figures 1 to 3 The atomizing device also includes a second sealing element 6, located on the side of the first sealing element 3 away from the mouthpiece 5 of the atomizing device. Typically, the second sealing element 6 is also made of silicone. The second sealing element 6 not only provides a seal, but also has grooves supporting the housing 21, the oil-absorbing element 22, and the sleeve 23. This improves the fixation of components such as the housing 21, the oil-absorbing element 22, and the sleeve 23, enhancing the stability of the atomizing device structure. Furthermore, the second sealing element 6, the first sealing element 3, the housing 21, and the oil cup 1 together form an oil storage cavity 7. This enclosure of the oil storage cavity 7 improves its sealing effect, preventing e-liquid leakage. This arrangement also facilitates the design of the first capillary oil guiding channel 31 and the second capillary oil guiding channel 32, improving their oil guiding effect.

[0064] In some embodiments, please refer to Figures 1 to 3 The inlet end of the first capillary oil guiding channel 31 ( Figure 3 The area shown in C is located at the end of the first seal 3 away from the second seal 6, and at the end of the first seal 3 near the housing 21; the inlet end of the second capillary oil channel 32 ( Figure 3The area shown in D is located at the end of the first seal 3 near the second seal 6. That is, the first capillary oil guiding channel 31 and the second capillary oil guiding channel 32 are located at opposite ends of the first seal 3 along its axial direction. This allows the e-liquid in the oil storage chamber to be guided through the first capillary oil guiding channel 31 and the second capillary oil guiding channel 32 to the location of the first through hole 211, thereby improving the flow effect of the first capillary oil guiding channel 31 and the second capillary oil guiding channel 32 on the e-liquid.

[0065] In some embodiments, please refer to Figures 1 to 3 The diameter *r* of the second capillary wicking channel 32 satisfies: 0.2 mm ≤ *r* ≤ 0.4 mm. By setting the diameter of the second capillary wicking channel 32 within this range, if the diameter is too large, the e-liquid cannot flow through the second capillary wicking channel 32 to the first through-hole 211; if the diameter is too small, the e-liquid in the oil storage chamber 7 is prone to leakage. With this configuration, when the e-liquid level in the oil storage chamber 7 is low, and when the atomizer is not in operation, the e-liquid cannot flow through the second capillary wicking channel 32 to the first through-hole 211; and when the atomizer is in operation, the e-liquid can flow through the second capillary wicking channel 32 to the first through-hole 211.

[0066] Furthermore, the diameter of the first capillary oil guiding channel 31 is the same as the diameter of the second capillary oil guiding channel 32. This arrangement can improve the convenience of opening the first capillary oil guiding channel 31 and the second capillary oil guiding channel 32 in the first seal 3.

[0067] For example, the diameter of the second capillary oil channel 32 can be 0.2mm, 0.22mm, 0.25mm, 0.3mm, 0.35mm, 0.38mm, 0.4mm, etc.
