Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette devices, and in particular to a cartridge and aerosol generating device. Background Technology

[0002] As consumers become increasingly health-conscious, traditional cigarettes are facing growing scrutiny due to the harmful substances such as tar and carbon monoxide produced during combustion. To reduce the health hazards of smoking, e-cigarettes have emerged. E-cigarettes use electric heating to atomize e-liquid into an inhalable aerosol, avoiding the combustion process of traditional cigarettes and thus significantly reducing the production of harmful substances.

[0003] In existing technologies, electronic cigarette devices typically employ a central airflow design. Specifically, e-liquid is delivered to the heating element through supply channels positioned on both sides. After being heated and atomized, it forms an aerosol that flows through the central airflow to the mouthpiece for the user to inhale.

[0004] Due to this structural design, the gas needs to travel through a complex path from the inlet, making multiple turns before reaching the central air passage and finally flowing to the nozzle. This complex airflow path causes aerosol particles to easily come into contact and collide during flow, leading to the formation of condensate inside the air passage. The formation of condensate can not only affect the taste and quality of the aerosol, reducing the user experience, but may also accumulate in the air passage, hindering the flow of the aerosol. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides a device for generating smoke cartridges and aerosols.

[0006] In a first aspect, embodiments of this utility model provide a cigarette cartridge for use in conjunction with an aerosol generating device, the cigarette cartridge comprising:

[0007] The shell has a mouthpiece end and a bottom end that are disposed opposite each other along the axial direction of the cartridge;

[0008] An aerosol channel is disposed within the housing and extends from the mouthpiece end along the axial direction. The aerosol channel includes a first aerosol channel and a second aerosol channel disposed opposite to each other along a first direction, the first direction being perpendicular to the axial direction of the cartridge.

[0009] An atomizing component is disposed within the housing, the atomizing component including an atomizing cavity extending along the first direction, the atomizing cavity being in communication with the aerosol channel;

[0010] An end cap is provided at the bottom end. The end cap has an opening and a hollow protrusion extending from the opening into the interior of the housing in a second direction. The opening and the hollow protrusion are connected. The hollow protrusion has an air inlet, which is connected to the atomizing chamber. The second direction is the direction from the bottom end toward the mouth end.

[0011] In the inhalation state, external air enters the interior of the hollow protrusion through the opening, flows out through the air inlet, flows into the atomization chamber and then into the atomization channel, reaching the mouthpiece. The air inlet has a bottom point and a top point along the second direction, and the angle formed between the direction of the bottom point toward the top point and the third direction is an obtuse angle, so that the external air flows out of the air inlet at an acute angle with the direction formed with the second direction. The third direction is the direction outward from the center of the cartridge in the first direction.

[0012] By adopting the above technical solution, the airflow path can be effectively optimized, the turning points in the airflow path can be reduced, and the formation of condensate can be significantly reduced, thereby improving the user experience and making the suction process smoother and less disruptive to the user.

[0013] Optionally, the distance between the vertex and the bottom point in the third direction is 0.1mm to 2.0mm.

The bottom of the liquid storage chamber is provided with a liquid outlet, which faces the atomizing component.

[0018] Optionally, the atomizing assembly includes a heating element having two liquid inlets and an inner cavity. The two liquid inlets are located on opposite sides of the top of the inner cavity along the first direction. The liquid inlets and the liquid outlet are connected. The inner cavity is used to buffer liquid from the storage cavity and heat the liquid. The atomizing cavity is connected to the inner cavity and is used to receive the product formed by atomizing the liquid heated in the inner cavity and the external air to mix and form an aerosol. The aerosol reaches the mouthpiece through the aerosol channel.

[0019] Optionally, a heating element is provided at the bottom of the inner cavity. The heating element has a porous structure with a porosity of 50% to 85% and a pore size of 0.05 μm to 2200 μm.

[0020] Optionally, the cartridge further includes a support and an electrode. The support is located inside the housing and is fixedly connected to the end cap. The bottom of the end cap is provided with an electrode port. The electrode is inserted into the electrode port and abuts against the bottom of the heating element to support the heating element, thereby fixing the heating element inside the support.

[0021] The support has a liquid guiding channel, which is connected to the liquid outlet and the liquid inlet respectively.

[0022] Optionally, the cartridge further includes a first seal and a second seal. The first seal is located between the bracket and the heating element to achieve a sealed connection between the liquid guiding channel and the liquid inlet.

To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0043] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] The terms “first”, “second”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0045] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0047] Firstly, reference Figures 1-8 As shown, this utility model provides a cigarette cartridge 0, used in conjunction with an aerosol generating device. The cigarette cartridge 0 includes a shell 1, an aerosol channel 11, an atomizing component 2, and an end cap 3. The shell 1 has a portion along the axial direction of the cigarette cartridge (e.g., along the axial direction of the cigarette cartridge). Figure 1 and Figure 3 The nozzle 101 and the bottom 102 are set relative to each other in the y-direction shown.

[0048] The aerosol channel 11 is disposed inside the housing 1, extending axially from the nozzle end 101 (e.g., along the axial direction). Figure 1 and Figure 3 The aerosol channel 11 extends along a first direction (e.g., the y-direction shown). Figures 1-3 The first aerosol channel 111 and the second aerosol channel 112 (shown in the x direction) are arranged relative to each other, the first direction (e.g. Figures 1-3 The x-direction shown is perpendicular to the axis of the cartridge (e.g., the x-direction). Figure 1 and Figure 3 (As shown in the y-direction). Compared to the single airway in existing technologies, this dual-airway design can better balance the airflow pressure distribution, making the airflow distribution more uniform. It avoids the local eddies and turbulence caused by concentrated airflow in a single airway, reducing the probability of aerosol particle collision and aggregation during transmission, thereby reducing the possibility of condensation. Furthermore, in actual use, the airway may become partially blocked due to foreign objects, condensation, etc. Once a single airway is partially blocked, the entire aerosol transmission will be severely affected. However, in the dual-airway design, if one airway has a problem (such as blockage), the other airway can still maintain basic aerosol delivery functions, reducing the probability of cartridge malfunction or performance degradation due to airway blockage, providing users with a more reliable user experience.

[0049] Continue to refer to Figure 1 and Figure 2 As shown, the first aerosol channel 111 and the second aerosol channel 112 extend along the first direction to the mouthpiece 101, forming a first smoke outlet 1110 and a second smoke outlet 1120 respectively for the user to inhale. In the actual use and storage of the e-cigarette cartridge 0, in the prior art, the cartridge usually has only one smoke outlet. When the smoke outlet is blocked, air cannot pass through. However, this embodiment has two smoke outlets, and the probability of both being blocked at the same time is lower than the probability of one smoke outlet being blocked. Relatively speaking, this reduces the probability of air not being able to pass through.

[0050] Atomizing component 2, disposed within housing 1, includes components along a first direction (e.g., Figures 1-3The atomizing cavity 21 extends along the first direction (e.g., the x-direction shown), and is connected to the atomization channel 11. Specifically, the atomizing cavity 21 extends along the first direction (e.g., the x-direction shown). Figures 1-3 The two sides of the x-direction shown are connected to the first aerosol channel 111 and the second aerosol channel 112, respectively.

[0051] End cap 3, located at the bottom end 102, has an opening 31 and a second direction from the opening (e.g., Figure 1 and Figure 6 The hollow protrusion 32 extends into the housing 1 in the y1 direction shown. The opening 31 is connected to the hollow protrusion 32. The hollow protrusion 32 is provided with an air inlet 321, which is connected to the atomizing chamber 21. The second direction is the direction from the bottom end 102 toward the nozzle end 101. Specifically, the number of air inlets 321 is at least one.

[0052] In the suction state, combined Figure 9 As shown, external air enters the interior of the hollow protrusion 32 through the opening 31, flows out through the air inlet 321, flows into the atomizing chamber 21 and then into the mist channel 11, reaching the mouthpiece 101. The air inlet 321 is along a second direction (e.g., Figure 1 and Figure 6 The y1 direction shown has a relative base point 3212 and vertex 3211, with the base point 3212 pointing towards the vertex 3211 (e.g., the direction of y1 direction). Figure 6 (as shown in direction a) and a third direction (e.g.) Figure 6 and Figure 7 The angle formed by the x1 direction shown is an obtuse angle (e.g., the angle formed by the x1 direction shown). Figure 6 (as shown by angle α). That is, the opening of the air intake 321 is oriented in the second direction (e.g., angle α). Figure 1 and Figure 6 The angle formed by the y1 direction (as shown) is acute. This causes the external air to... Figure 1 and Figure 6 The direction formed by the y1 direction shown is an acute angle, from which the air flows out of the air inlet 321, that is, the direction in which the outside air flows out of the air inlet (e.g., the direction of the airflow). Figure 6 (as shown in direction b) and the second direction (e.g.) Figure 1 and Figure 6 The angle formed by the y1 direction shown is an acute angle (e.g., the angle formed by the y1 direction shown). Figure 6 (as shown by β angle), third direction (e.g.) Figure 6 and Figure 7 The x1 direction shown is in the first direction (e.g., Figures 1-3 (The x-direction shown) is the direction from the center of the smoke bomb outwards.

[0053] By adopting the above technical solution, this utility model, through the design of opening 31, air inlet 321, atomizing chamber 21, first atomization channel 111, and second atomization channel 112, allows external air to first enter the hollow protrusion 32 from opening 31 along the second direction during inhalation. The external air then flows out from air inlet 321 at an angle less than 90° to the second direction. This controls the flow direction of the external air, thereby reducing the degree of deflection and effectively preventing droplet splashing and condensation caused by violent airflow impact, allowing the air to enter the atomizing chamber 21 more smoothly. After the external air mixes in the atomizing chamber 21 to form an aerosol, it flows into the axially extending first atomization channel 111 and second atomization channel 112. The dual-channel design of atomization channel 11 also improves the dispersion of the airflow, making the aerosol distribution more uniform within the channels and further reducing condensation formation. The aerosol then reaches the mouthpiece 101, where the user can inhale through the first smoke outlet 1110 and the second smoke outlet 1120.

[0054] Compared to existing technologies, the present invention's cartridge effectively optimizes the airflow path, reduces the number of turns in the airflow path, makes the aerosol flow more stable, and significantly reduces the probability and amount of condensate generation, thereby improving the user experience and making the user's inhalation process smoother with less condensate interference.

[0055] In some other possible embodiments provided by this utility model, the aerosol channel 11 is axial (e.g.) Figure 1 and Figure 3 The cross-sectional areas at different locations along the y-direction (as shown) are substantially the same. Specifically, the first aerosol channel 111 and the second aerosol channel 112 are axially (e.g., along the y-direction). Figure 1 and Figure 3 The cross-sectional areas at different locations along the y-direction (as shown) are substantially the same. "Substantially the same" means identical, substantially identical, or with differences within an acceptable range for industrial production. For example, the ratio of the difference in area between any two different cross-sectional locations to the area of ​​one of the cross-sectional locations is in the range of 0–3, and / or the difference in area between any two different cross-sectional locations is 0–10 mm. 2 It should be noted that the difference in cross-sectional area between any two different locations refers to the larger area minus the smaller area. Since the cross-sectional areas at different locations are essentially the same, the aerosol flow rate will not fluctuate due to sudden changes in the cross-sectional area of ​​the aerosol channel 11 during transmission. This ensures a balanced airflow velocity within the aerosol channel 11, resulting in a more uniform aerosol distribution during transmission and further reducing localized condensation or particle deposition.

[0056] Furthermore, the aerosol channel 11 is axially (e.g.) Figure 1 and Figure 3The first aerosol channel 111 and the second aerosol channel 112 extend along the axial direction (e.g., in the y-direction shown). Exemplarily, the first aerosol channel 111 and the second aerosol channel 112 extend along the axial direction (e.g., in the y-direction shown). Figure 1 and Figure 3 (As shown in the y-direction) Equal diameter extension.

[0057] In some other possible embodiments provided by this utility model, a gap exists between the inner sidewall 10 of the housing and the sidewall 110 of the aerosol channel in a direction perpendicular to the axial direction. Specifically, the inner sidewall 10 of the housing and the sidewall 110 of the aerosol channel do not coincide, that is, the inner sidewall 10 of the housing does not constitute the sidewall 110 of the aerosol channel. Exemplarily, when the aerosol channel 11 is cylindrical, the direction perpendicular to the axial direction is the radial direction of the aerosol channel 11, that is, a gap exists between the inner sidewall 10 of the housing and the sidewall 110 of the aerosol channel in this radial direction. In other words, there is a gap surrounding the aerosol channel 11 in the radial direction of the aerosol channel 11 between the inner sidewall 10 of the housing and the sidewall 110 of the aerosol channel.

[0058] Wherein, axial direction, for example Figure 1 and Figure 3 The y-direction shown refers to directions perpendicular to the axial direction, such as the first direction, the third direction, and the fourth direction. The first direction is, for example... Figures 1-3 The x-direction shown, the third direction, for example Figure 6 and Figure 7 The x1 direction shown, the fourth direction, for example Figure 2 h direction shown.

[0059] The gap between the inner wall 10 of the housing and the side wall 110 of the aerosol channel serves two purposes. First, the gap provides thermal insulation, reducing the influence of the external ambient temperature on the temperature inside the aerosol channel 11 and preventing condensation of aerosols due to temperature differences. Second, when the housing 1 is deformed by external pressure, the gap provides a buffer space for the deformation, reducing the risk of changes in the cross-sectional area of ​​the aerosol channel 11 due to deformation, thus preventing changes in aerosol flow rate and avoiding condensation caused by changes in flow rate.

[0060] In some other possible embodiments provided by this utility model, in order to optimize the overall structure of the cigarette cartridge 0, the cigarette cartridge 0 has a central axis. The distance between the first aerosol channel 111 and the central axis in the first direction is a first distance, which is 1 to 15 mm; the distance between the second aerosol channel 112 and the central axis in the first direction is a second distance, which is 1 to 15 mm. The difference between the first distance and the second distance does not exceed 10 mm.

[0061] In some other possible embodiments provided by this utility model, vertex 3211 and bottom point 3212 are in a third direction (e.g. Figure 6and Figure 7 They are offset relative to each other in the x1 direction (as shown). Specifically, refer to... Figure 7 As shown, vertex 3211 and base 3212 are in a third direction (e.g. Figure 6 and Figure 7 The distance d1 in the x1 direction (as shown) is 0.1mm to 2.0mm. Preferably, the vertex 3211 and the base point 3212 are in a third direction (e.g., Figure 6 and Figure 7 The distance d1 in the x1 direction (as shown) is 0.1mm to 0.6mm. The existence of distance d1 means that the precision requirements for production can be reduced during processing, making processing more efficient. It also greatly reduces the risk of mold damage and the risk of flash causing at least partial blockage of the air inlet 321. On the other hand, by adjusting the size of distance d1, the flow direction of external air out of the air inlet can be optimized (e.g., Figure 6 (as shown in direction b) and the second direction (e.g.) Figure 1 and Figure 6 The specific angle formed by the y1 direction (as shown) allows external air to enter the atomization chamber 21 more smoothly and evenly, reducing the formation of condensate.

[0062] In some other possible embodiments provided by this utility model, the number of air inlets 321 is multiple, and the multiple air inlets 321 are along the circumference of the hollow protrusion 32 (e.g. Figure 4 The distribution is shown in the z-direction. This invention does not limit the number of air inlets 321.

[0063] For example, such as Figures 4-7 In the embodiment shown, there are two air inlets 321, and the two air inlets 321 are along a third direction (e.g., Figure 7 The air inlet 321 and the aerosol channel 11 are located on both sides of the hollow protrusion 32 in the first direction (e.g., the x1 direction shown). In this embodiment, the air inlet 321 and the aerosol channel 11 are located in the first direction (e.g., the x1 direction shown) Figures 1-3The air inlet 321 and the atomization channel 11 are offset relative to each other in the x-direction shown. This extends the flow path of external air within the atomization chamber 21, allowing for more thorough mixing of the air to form an aerosol, improving atomization efficiency, and resulting in a fuller aerosol and better taste for the user. However, when the air inlet 321 and the atomization channel 11 are not offset in the first direction (i.e., when they are axially opposite each other), external air may flow directly into the atomization channel 11 at a relatively high speed, leading to insufficient mixing time and affecting the uniformity of the aerosol. Furthermore, the external air is buffered within the atomization chamber 21, reducing the probability of droplets directly impacting the atomization channel 11, thus reducing the risk of condensate accumulation in the atomization channel 11. For example, when the air inlet 321 and the atomization channel 11 are axially opposite each other, external air can carry incompletely atomized droplets at a high speed, directly impacting the inner wall of the atomization channel 11, causing condensate accumulation, which may affect atomization performance or even cause leakage in the long term.

[0064] In some other possible embodiments provided by this utility model, the hollow protrusion 32 has a top wall 3201 and a side wall 3202, and the air inlet 321 is located at the junction of the top wall 3201 and the side wall 3202. Specifically, a notch is formed at the junction of the top wall 3201 and the side wall 3202, which serves as the air inlet 321.

[0065] In some other possible embodiments provided by this utility model, the hollow protrusion 32 has a sidewall 3202, and the air inlet 321 is located on the sidewall 3202. When liquid is present near the air inlet 321, the liquid usually flows in the cartridge due to gravity. In this embodiment, the air inlet 321 is perpendicular to the direction of gravity, that is, the air inlet 321 is not exposed to the direction of gravity, making it difficult for liquid to leak out of the shell 1 through the air inlet 321 under the action of gravity, further enhancing the anti-leakage performance. Exemplarily, the air inlet 321 is made by a perforation process.

[0066] In any of the above embodiments, the air inlet 321 is provided with a lower edge 3213, which extends from the bottom point 3212 toward the housing 1, and the direction of extension of the lower edge (e.g. Figure 6 The aforementioned c-direction) and a third direction (e.g.) Figure 6 and Figure 7 The angle formed by the x1 direction shown (e.g.) Figure 6 The γ angle shown is an obtuse angle. In this embodiment, the lower edge 3213 is inclined relative to the axial direction, and the direction of extension of the lower edge is, for example, as follows: Figure 6As shown in direction c. Even if there is liquid (such as condensate or e-liquid) near the air inlet 321, the liquid is most likely to come into contact with or drip onto the surface of the lower edge 3213 due to gravity. The inclined surface of the lower edge 3213 will cause the liquid to continue to slide down into the gap formed in the third direction between the lower edge 3213 and the shell 1 due to gravity. That is, the liquid is retained in the cartridge 0 and prevents it from leaking to the outside of the shell 1.

[0067] In some other possible embodiments provided by this utility model, the e-cigarette cartridge 0 includes a liquid storage chamber 12, which is disposed within the housing 1 and located between the first atomization channel 111 and the second atomization channel 112 along a first direction. The bottom of the liquid storage chamber 12 is provided with a liquid outlet 121, which faces the atomizing assembly 2. Preferably, the liquid storage chamber 12 is located at the center position between the first atomization channel 111 and the second atomization channel 112 along the first direction.

[0068] Traditional single-airflow structures have two opposing e-liquid supply channels on either side of the central airflow, each with a corresponding e-liquid outlet. During use, depending on the user's posture, such as tilting at an angle, one outlet may become partially uncovered, reducing the amount of e-liquid received by the heating element per unit time. This can lead to uneven e-liquid immersion and even insufficient atomization. In contrast, even when the user holds the cartridge 0 at different angles, such as tilting its axis relative to gravity, the outlet 121 in this embodiment maintains greater contact with the e-liquid, significantly reducing the risk of insufficient e-liquid supply and thus mitigating the problem of insufficient atomization.

[0069] In some other possible embodiments provided by this utility model, the atomizing component 2 includes a heating element 22, which has two liquid inlets 2201 and an inner cavity 2202. The two liquid inlets 2201 are respectively located on both sides of the top of the inner cavity 2202 along a first direction. The liquid inlets 2201 and the liquid outlet 121 are connected. The inner cavity 2202 is used to buffer the liquid from the liquid storage chamber 12 and heat the liquid. The atomizing chamber 21 is connected to the inner cavity 2202 and is used to receive the product formed by the atomization of the heated liquid in the inner cavity 2202 and external air to mix and form an aerosol. The aerosol reaches the mouth tip 101 through the aerosol channel 11. Exemplarily, the heating element 22 is, for example, a ceramic heating element, and this utility model does not specifically limit it.

[0070] This allows the liquid in the storage chamber 12 to flow more evenly and efficiently into the inner cavity 2202. Compared to single-sided liquid inlet, the double-sided liquid inlets 2201 can avoid uneven liquid distribution caused by excessively fast or slow local liquid inlet, ensuring that all parts of the inner cavity 2202 receive sufficient liquid in a timely manner. As a liquid buffer and heating area, the inner cavity 2202 can effectively control the amount of liquid entering, preventing excessive or insufficient liquid from adversely affecting the heating effect. In addition, the inner cavity 2202 is connected to the atomizing chamber 21. The inner cavity 2202 efficiently heats the e-liquid to produce atomized products, which enter the atomizing chamber 21 and mix thoroughly with the external air to form a stable aerosol.

[0071] Furthermore, a heating element 22021 is provided at the bottom of the inner cavity 2202. The heating element 22021 has a porous structure with a porosity of 50% to 85% and a pore size of 0.05 μm to 2200 μm. In this embodiment, the porous structure of the heating element 22021 provides strong liquid absorption capacity. Simultaneously, the high porosity gives the heating element 22021 a large specific surface area, allowing for more thorough contact with the liquid in the inner cavity 2202. Sufficient contact means the liquid can be heated quickly and uniformly, preventing abnormal liquid flow due to localized overheating or uneven heating, thereby reducing the risk of leakage caused by unstable liquid movement. For example, uneven heating may cause irregular pressure changes within the cavity, pushing the liquid towards potential gaps or weak points, leading to leakage. In addition, the heating element 22021 also has a suitable pore size range, allowing the liquid to maintain a relatively stable state through surface tension and pore resistance, further reducing the probability of leakage.

[0072] In some other possible embodiments provided by this utility model, the cartridge 0 further includes a support 4 and an electrode 6. The support 4 is located inside the housing 1 and is fixedly connected to the end cap 3. The bottom of the end cap 3 is provided with an electrode port 33. The electrode 6 is inserted into the electrode port 33 and abuts against the bottom of the heating element 22 to support the heating element 22, thereby fixing the heating element 22 inside the support 4. This stable installation method ensures that the heating element 22 will not shift due to external forces such as shaking or vibration during the use of the cartridge 0, ensuring the stability of the connection between the heating element 22 and other components, thereby maintaining the stable working performance of the cartridge 0 and avoiding problems such as short circuits and uneven heating caused by the displacement of the heating element 22. In this embodiment, the electrode 6 and the heating element 22021 are electrically connected.

[0073] Furthermore, the interference fit between electrode 6 and electrode port 33 further enhances the sealing performance and prevents liquid leakage.

[0074] The support 4 has a liquid guiding channel 41, which is connected to the liquid outlet 121 and the liquid inlet 2201. That is, the liquid in the storage chamber 12 can flow evenly and simultaneously through the liquid outlet 121 and along the liquid guiding channel 41 to the two liquid inlets 2201 of the heating element 22, ensuring that the heating element 22021 is fully wetted and reducing the risk of uneven oil flow. For example, a flow divider is provided inside the liquid guiding channel 41 to form a "V"-shaped flow divider structure inside the liquid guiding channel 41, so that the liquid outlet 121 can be connected to the two liquid inlets 2201 through the liquid guiding channel 41.

[0075] Furthermore, the cartridge also includes a sealing element 5, which comprises a first sealing element 51 and a second sealing element 52. The first sealing element 51 is located between the support 4 and the heating element 22 to achieve a sealed connection between the liquid guiding channel 41 and the liquid inlet 2201. The second sealing element 52 is sleeved on the outer periphery of the liquid guiding channel 41 and is located axially between the bottom of the liquid storage cavity 12 and the support 4 to achieve a sealed connection between the liquid outlet 121 and the liquid guiding channel 41. In other words, through the double sealing of the first sealing element 51 and the second sealing element 52, the liquid in the liquid storage cavity 12 flows out from the liquid outlet 121, flows through the liquid guiding channel 41 into the two liquid inlets 2201 respectively, and reaches the inner cavity 2202. The entire liquid flow path is fully sealed. This not only effectively improves the leak-proof performance and atomization stability of the cartridge 0, but also ensures that other components inside the cartridge 0 are not corroded by liquid, maintaining the overall performance stability of the cartridge 0.

[0076] For example, the bracket 4 and the second seal 52 can be integrally molded, reducing assembly steps.

[0077] For example, the bracket 4 and the second seal 52 are respectively machined to facilitate processing.

[0078] Furthermore, the housing 1 and the end cap 3 are fixedly connected, and there is an axial gap between the bottom of the heating element 22 and the bottom of the end cap 3. The gap and the housing 1 define the atomizing chamber 21. Specifically, the atomizing chamber 21, the first atomizing channel 111 and the second atomizing channel 112 are connected to form a U-shaped channel, which makes the flow path of the aerosol simpler.

[0079] In some other possible embodiments provided by this utility model, the first aerosol channel 111 extends axially from the first smoke outlet 1110, passes through the second seal 52 and the bracket 4, and communicates with the atomizing chamber 21. The second aerosol channel 112 extends axially from the second smoke outlet 1120, passes through the second seal 52 and the bracket 4, and communicates with the atomizing chamber 21. By adopting the above technical solution, the integrated structure of the aerosol channel 11 extending axially can effectively improve the sealing performance of the aerosol during transmission in the aerosol channel 11, reducing the risk of aerosol leakage. Simultaneously, the aerosol channel 11's passage through the second seal 52 and the bracket 4 allows the aerosol channel 11 to receive support from the second seal 52 and the bracket 4, enhancing its stability and resistance to deformation, thereby effectively resisting displacement and deformation caused by vibration or external forces, and simplifying assembly.

[0080] Alternatively, the first aerosol channel 111 includes a first air passage 1111, a second air passage 1112, and a third air passage 1113, which are axially connected. That is, the first aerosol channel 11 is composed of the first air passage 1111, the second air passage 1112, and the third air passage 1113 connected sequentially along the axial direction. The second aerosol channel 112 includes a fourth air passage 1121, a fifth air passage 1122, and a sixth air passage 1123, which are axially connected. That is, the second aerosol channel 112 is composed of the fourth air passage 1121, the fifth air passage 1122, and the sixth air passage 1123 connected sequentially along the axial direction. The first air passage 1111 extends axially from the first smoke outlet 1110, the fourth air passage 1121 extends axially from the second smoke outlet 1120, and the second air passage 1112 and the fifth air passage 1122 are disposed on the second sealing member 52 along the first direction (e.g. Figures 1-3 On both sides of the bracket 4 along the first direction (as shown in the x direction), the third air passage 1113 and the sixth air passage 1123 are provided. Figures 1-3 On both sides (in the x direction shown), the third air passage 1113 and the sixth air passage 1123 are respectively connected to the atomizing chamber 21. By modularizing the first atomizing channel 111 and the second atomizing channel 112, it is not only convenient to inspect and disassemble the first atomizing channel 111 and the second atomizing channel 112, but also convenient to process each air passage, reducing the difficulty of manufacturing and assembly.

[0081] Secondly, embodiments of this utility model also provide an aerosol generating device, including a cartridge 0 as in any embodiment of the first aspect and a power supply component. The power supply component is a structure in the aerosol generating device involving circuitry and power supply, including parts for power storage and transmission, such as a circuit board, battery, etc. The cartridge 0 includes an aerosol generating matrix and a heating element. In this utility model's aerosol generating device, the power supply component and the cartridge 0 are distributed vertically along the axial direction; for example, the power supply component is located at the upper part of the aerosol generating device, and the cartridge is located at the lower part. In this embodiment, the power supply component is located at the lower part of the aerosol generating device, and the cartridge 0 is located at the upper part. Specifically, the power supply component is electrically connected to the electrode 6, thereby supplying power to the cartridge 0 to atomize the aerosol generating matrix and generate aerosol.

[0082] By adopting the above technical solution, the airflow path is effectively optimized, the aerosol flow is more stable, the formation of condensate is significantly reduced, and the oil leakage prevention performance is enhanced, thereby improving the user experience and making the suction process smoother without the trouble of condensate accumulation or oil leakage.

[0083] Furthermore, the cartridge 0 also includes a magnet 34, which is embedded in the bottom of the end cap 3, allowing the cartridge 0 and the power assembly to be detachably connected via magnetic force. This connection method is not only convenient, but also ensures a secure connection between the cartridge 0 and the power assembly while allowing users to easily disassemble and install the cartridge as needed.
