Description

[0001] CARTRIDGE AND DEVICE FOR AEROSOL PROVISION SYSTEM AND AEROSOL PROVISION SYSTEM

[0002] Technical Field

[0003] This invention is related to the field of aerosol provision, particularly relating to a cartridge and a cigarette device for an aerosol provision system and the aerosol provision system.

[0004] Background

[0005] Electronic cigarette-type aerosol provision systems, which heat but do not combust aerosol-generating materials containing aerosol-forming substrates (such as tobacco), generally utilize heaters or similar devices to heat the aerosol-generating materials to a sufficiently high temperature for the generation of aerosol for puffing by the user. The structural design of the aerosol provision system significantly influences the taste of the electronic cigarette, with draw resistance being an essential parameter affecting taste. A higher draw resistance in electronic cigarettes results in reduced air intake, enhancing the richness of the taste and providing a stronger throat hit. However, excessive draw resistance can lead to insufficient air intake, causing airflow issues. On the other hand, too low draw resistance increases air intake, resulting in dispersed vapor and a less satisfying taste.

[0006] To address the aforementioned issues, the aerosol provision systems in existing technologies typically achieve the desired draw resistance by adjusting the size of the air inlet. However, the air inlet is directly exposed to the external environment, making it susceptible to issues such as blockage and deformation. This exposure results in the actual air intake deviating from expectations, making it challenging to achieve the desired draw resistance. On the other hand, the internal structure of the aerosol provision system is complex, and the impact on airflow is difficult to quantify. This complexity makes it challenging to achieve the expected draw resistance solely through adjusting the size of the air inlet.

[0007] Therefore, there is an urgent need for a new structure for the aerosol provision system to solve one or more of these technical issues. Summary of Invention

The aerosol-modifying agent may, for example, be an additive or a sorbent. The aerosol-modifying agent may, for example, comprise one or more of a flavourant, a colourant, water, and a carbon adsorbent. The aerosol-modifying agent may, for example, be a solid, a liquid, or a gel. The aerosol-modifying agent may be in powder, thread or granule form. The aerosol-modifying agent may be free from filtration material.

[0112] An aerosol generator is an apparatus configured to cause aerosol to be generated from the aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol-generating material to heat energy, so as to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, the aerosol generator is configured to cause an aerosol to be generated from the aerosol-generating material without heating. For example, the aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0113] The present disclosure relates to aerosol delivery systems (which may also be referred to as vapour delivery systems) such as nebulisers or e-cigarettes. Throughout the following description the term "e-cigarette" or "electronic cigarette" may sometimes be used, but it will be appreciated this term may be used interchangeably with aerosol delivery system I device and electronic aerosol delivery system I device. Furthermore, and as is common in the technical field, the terms "aerosol" and "vapour", and related terms such as "vaporise", "volatilise" and "aerosolise", may generally be used interchangeably.

[0114] Aerosol delivery systems (e-cigarettes) often, though not always, comprise a modular assembly comprising a reusable device part and a replaceable (disposable / consumable) cartridge part. Often, the replaceable cartridge part will comprise the aerosol-generating material and the vaporiser (which may collectively be called a “cartomizer”) and the reusable device part will comprise the power provision (e.g. rechargeable power source) and control circuitry. It will be appreciated these different parts may comprise further elements depending on functionality. For example, the reusable device part will often comprise a user interface for receiving user input and displaying operating status characteristics, and the replaceable cartridge device part in some cases comprises a temperature sensor for helping to control temperature. Cartridges are electrically and mechanically coupled to the control unit for use, for example using a screw thread, bayonet, or magnetic coupling with appropriately arranged electrical contacts. When the aerosol-generating material in a cartridge is exhausted, or the user wishes to switch to a different cartridge having a different aerosol-generating material, the cartridge may be removed from the reusable part and a replacement cartridge attached in its place. Systems and devices conforming to this type of two-part modular configuration may generally be referred to as two-part systems / devices.

[0115] It is common for electronic cigarettes to have a generally elongate shape. For the sake of providing a concrete example, certain embodiments of the disclosure will be taken to comprise this kind of generally elongate two-part system employing disposable cartridges. However, it will be appreciated that the underlying principles described herein may equally be adopted for different configurations, for example single-part systems or modular systems comprising more than two parts, refillable devices and single-use disposables, as well as other overall shapes, for example based on so-called box-mod high performance devices that typically have a boxier shape. More generally, it will be appreciated certain embodiments of the disclosure are based on aerosol delivery systems which are operationally configured to provide functionality in accordance with the principles described herein and the constructional aspects of systems configured to provide the functionality in accordance with certain embodiments of the disclosure is not of primary significance.

[0116] As described in the technical background, existing aerosol provision systems typically achieve the desired draw resistance by adjusting the size of the air inlet. However, the air inlet is directly exposed to the external environment, making it susceptible to issues such as blockage and deformation. This exposure results in the actual air intake deviating from expectations, making it challenging to achieve the desired draw resistance. On the other hand, the internal structure of aerosol provision systems is complex, and the impact on airflow is difficult to quantify. This complexity makes it challenging to achieve the expected draw resistance solely through adjusting the size of the air inlet. In light of these challenges, this application introduces a novel structure for an aerosol provision system capable of regulating the airflow entering the atomizing chamber by components outside the air inlet. This design ensures that the cartridge achieves the expected draw resistance.

[0117] With reference to the accompanying drawings, the specific details of the embodiment of this application will be described.

[0118] Embodiment One

[0119] Figure 1 is a schematic diagram of the structure of the cartridge in the aerosol provision system provided in the embodiment of this application. Figure 2 is a sectional schematic diagram of the cartridge in the aerosol provision system provided in the embodiment of this application. As shown in Figure 1 and Figure 2, the aerosol provision system's cartridge generally comprises a cartridge housing 100, a mouthpiece component 200, a liquid storage compartment 300, and an atomizing core 400. Inside the cartridge housing 100, there is a containment space, an atomizing chamber 410, and an airway 500. The atomizing chamber 410 is in fluid communication with the airway 500. Components such as the liquid storage compartment 300 and the atomizing core 400 are either fully or partially located within the containment space. The internal structure of the liquid storage compartment 300 includes a liquid storage chamber 310 designed to accommodate aerosol-generating materials, such as e-liquid. The atomizing core 400 comprises an atomizing chamber 410 for accommodating a heater. The atomizing chamber 410 is fluidly connected to the liquid storage chamber 310, allowing aerosol-generating materials from the liquid storage chamber 310 to enter the atomizing chamber 410, where they form aerosol after being heated by the heater component. The atomizing chamber 410 is fluidly connected to the airway through the exit of the mouthpiece component 200, allowing users to inhale the aerosol from the exit of the mouthpiece component 200. In this embodiment, specific constraints are not applied to the cartridge housing 100 and the mouthpiece component 200. Without deviating from the conceptual basis of the invention in this application, they can be chosen or configured based on the actual product requirements.

[0120] The atomizing core comprises, at least, a base 460 for forming the bottom wall of the atomizing chamber 410. The base 460 of the atomizing core is equipped with an intercepting air hole 600, which serves as the airflow inlet for the airway. The fluid flux at the intercepting air hole 600 is minimized within the airway. By placing the intercepting air hole on the base of the atomizing core and ensuring that the fluid flux at the intercepting air hole is the smallest in the airway, it is achieved that the airflow entering the atomizing chamber can be regulated by components outside the air inlet. This design ensures that the cartridge achieves the expected draw resistance.

[0121] It is understood that, the aerosol provision system comprises interconnected air passages (not shown in the figure) and an air inlet. The air passages (not shown in the figure) are in fluid communication with the external atmosphere of the aerosol provision system through the air inlet (not shown in the figure). Since the intercepting air hole 600 serves as the airflow inlet for the air passage 500, and the air passage 500 is connected to the atomizing chamber, the atomizing chamber 410 is in communication with the external atmosphere. Due to the minimum fluid flux at the intercepting air hole throughout the airway, it ensures that the airflow entering the atomizing chamber is minimized. This achieves the goal of adjusting the size of the intercepting air hole to attain the expected draw resistance in the cartridge (or aerosol provision system).

[0122] Preferably, the air passage 500 has a vertically extending portion within the atomizing chamber 410 along the length direction of the cartridge. In other words, at least a portion of the air passage 500 is vertically oriented along the length direction of the cartridge. It can be understood that the orientation of another portion of the air passage 500 can be adaptively adjusted based on the internal structure of the cartridge, such as being set along a direction perpendicular to the length direction of the cartridge or forming a curved shape. These details are not explicitly reiterated here.

[0123] Figure 3 is an exploded view of the atomizing core provided in the embodiment of this application. As shown in Figure 3, the atomizing core comprises a heater, an atomizing chamber 410 for accommodating the heater, a first fixing member 420, and a second fixing member 430 for securing the heater, an airway silicone component 440, a base 460 for the atomizing core, and a first sealing member 470. The heater and the airway silicone component 440 are both interlocked between the first fixing member 420 and the second fixing member 430. The heater includes stacked heating elements 451 and oil guide elements 452, with the heating elements 451 positioned between the oil guide elements 452 and the airflow channel. In a specific implementation, the surface of the airway silicone component 440 is equipped with multiple grooves to collect condensate formed by aerosol condensation in the atomizing chamber, preventing condensate leakage. The internal structure of the airway silicone component 440 comprises a channel forming part of the air passage 500. One end of the channel is in communication with the cavity at the bottom of the base 460 of the atomizing core, thereby connecting with the intercepting air hole 600. The other end is in communication with the internal air passage 500 of the cartridge, connecting with the exit of the mouthpiece component.

[0124] As an illustrative example and not limiting in nature, the heating element 451 has a mesh-like structure, and the openings in the mesh structure can be circular or of any polygonal shape. The heating element 451 has an atomizing surface, and this surface is parallel to the airflow direction within the air passage. This configuration allows the aerosol generated on the atomizing surface to be quickly drawn along the airway and to the exit of the mouthpiece component as the airflow progresses. In a specific embodiment, the atomizing surface is exposed within the vertically extending air passage inside the atomizing chamber, and it is parallel to this vertically extending airway.

[0125] As an illustrative example and not limiting in nature, the oil guide element 452 has a lower oil guiding rate on the side near the heating element 451 than on the side away from the heating element 451 . The oil absorption rate on the side near the heating element 451 is higher than the oil absorption rate on the side away from the heating element 451. This configuration ensures that the oil guide element 452 near the heating element 451 exhibits a higher oil guiding rate, improving its oil guiding efficiency. Meanwhile, the portion away from the heating element 451 has a higher oil absorption rate, enhancing the oil absorption capacity at the heating element 451 .

[0126] Further referring to Figure 3, the top of the base 460 of the atomizing core (i.e. , the end near the atomizing chamber 410) forms a leak-proof cavity for collecting condensate. A first sealing member 470 is placed over the top of the leak-proof cavity. The bottom of the base 460 of the atomizing core (i.e., the end away from the atomizing chamber 410) forms a cavity 461 , and the intercepting air hole 600 is opened at the end of the base 460 away from the atomizing chamber 410. The intercepting air hole 600 connects the cavity 461 to the air inlet channel (not shown in the diagram). In specific implementations, the axial direction of the intercepting air hole 600 is angled relative to the length direction of the cartridge, preferably perpendicular to the length direction of the cartridge.

[0127] As a preferred embodiment, in the embodiment of the present application, there is no specific limitation on the number and size of the intercepting air holes 600. In specific implementations, they are set according to the expected suction resistance of the cartridge. As an illustrative and non-limiting explanation, in this embodiment, the number of intercepting air holes 600 comprises at least two, and at least two intercepting air holes 600 are circumferentially spaced along the base 460 of the atomizing core.

[0128] As a preferred embodiment, in the embodiment of the present application, the intercepting air holes 600 extend along a direction perpendicular to the length direction of the cartridge (i.e., the transverse direction of the cartridge). The intercepting air holes 600 are oriented towards a surface on the side facing the cartridge housing, and there is a first gap between the surface of the intercepting air holes 600 facing the cartridge housing and the cartridge housing. By setting the first gap between the surface of the intercepting air holes facing the cartridge housing and the cartridge housing, gas in the airflow channel can enter the intercepting air holes through this first gap.

[0129] As shown in Figure 4, in the embodiment of the present application, the bottom surface 461 of the base 460 of the atomizing core is also provided with air vent holes 462. The fluid communication between the atomizing chamber 410 and the cavity 461 is achieved through the air vent holes 462. The intercepting air holes 600, cavity 461 , and air vent holes 462 are fluidly connected in sequence.

[0130] It is understood that, in the embodiment of the present application, there is no specific limitation on the shape of the intercepting air holes 600. Without departing from the conceptual idea of the present application, any known shape may be used for the intercepting air holes 600. For example, the intercepting air holes 600 can have any shape such as circular, square, rectangular, rhombic, trapezoidal, triangular, and polygonal shapes, including but not limited to equilateral or non-equilateral pentagons, hexagons, octagons, and so on, without being exhaustive.

[0131] Figure 5 is a structural schematic diagram of the liquid storage compartment provided in the embodiment of this application. As shown in Figure 5, as a preferred embodiment, the liquid storage compartment 300 comprises an outer wall 320. The outer wall 320 of the liquid storage compartment 300 can be integrally formed with the cartridge housing 100, constituting a part of the cartridge housing 100. Alternatively, the outer wall 320 and the cartridge housing 100 can be independent components. In a specific embodiment, the outer wall 320 and the cartridge housing 100 are independent components, where the outer wall 320 is positioned outside the atomizing core 400. The liquid storage compartment 310 is surrounded by the outer wall 320 and a portion of the surface of the atomizing core 400, and the liquid storage compartment 310 is in fluid communication with the atomizing chamber 410 of the atomizing core 400 through a liquid inlet structure. This allows the aerosol-generating material in the liquid storage compartment 310 to enter the atomizing chamber 410 through the liquid inlet structure and be heated by the heater to form an aerosol.

[0132] Further preferably, the system comprises a sealing member 700 for sealing between the atomizing core 400 and the liquid storage compartment 310. In a specific implementation, the shape and size of the sealing member 700 are adapted to the size and shape of the end of the atomizing core 400 near the liquid storage compartment 310, with no specific limitation here. The outer wall 320 of the liquid storage compartment 300 is positioned around the sealing member 700, and the portion of the outer wall 320 in contact with the sealing member 700 is assembled with interference fit. This prevents leakage of the aerosol-generating material in the liquid storage compartment, avoiding contamination of other components such as the battery module in the aerosol provision system. Simultaneously, to achieve fluid communication between the liquid storage compartment 310 and the atomizing chamber 410, the sealing member 700 has a liquid inlet hole 710, allowing the aerosol-generating material in the liquid storage compartment 310 to flow out through this liquid inlet hole 710.

[0133] Embodiment Two

[0134] Corresponding to the above-mentioned embodiment one, the present application also provides an aerosol provision system. The system comprises a cartridge as disclosed in any one of embodiment one, a shell 800 with a battery module containing chamber, an air inlet 900, an air inlet channel (not shown in the figure), and a battery module 1000. In this embodiment, content that is the same or similar to embodiment one can be referred to in the previous introduction, and will not be repeated here.

[0135] Figure 6 is a structural schematic diagram of the aerosol provision system provided in the embodiment of this application. Figure 7 is a sectional schematic diagram of the aerosol provision system provided in the embodiment of this application. As shown in Figure 6 and Figure 7, the air inlet 900 is positioned on the shell 800, exemplarily, the air inlet 900 is set at one end of the shell 800 away from the mouthpiece component 200; an air passage is formed within the shell 800, being in fluid communication with the air inlet 900 and the intercepting air hole 600 through the air passage; the battery module 1000 is positioned inside the shell 800.

[0136] In a specific embodiment, the air inlet 900 is located on the circumferential surface of the shell 800.

[0137] In a specific embodiment, along the transverse direction of the cartridge, the air inlet 900 is located on the same cross section as the intercepting air hole 600.

[0138] The battery module 1000 comprises a battery pack housing (not shown in figure), the battery pack housing is provided with a battery containing chamber (not shown in figure) inside, there is a second gap between the battery pack housing and the shell 800, and the second gap forms the air inlet channel.

[0139] It is understood that the fluid flux at the intercepting air hole is the smallest in the entire air passage and the inlet channel. This achieves the adjustment of the airflow entering the atomizing chamber by the intercepting air hole, allowing the aerosol system to achieve the expected suction resistance.

[0140] It is understood that, in this embodiment, the cartridge housing 100 and the shell 800 can be integrally formed, meaning the cartridge housing 100 forms part of the shell 800. Alternatively, they can be separate parts, and this application does not specifically limit this. As an illustrative and non-limiting explanation, in this embodiment, the cartridge housing 100 and the shell 800 are integrally formed.

[0141] In the embodiment of this application, there is no specific limitation on the specific composition of the battery module 1000. Any known battery module can be used in this embodiment without departing from the conceptualization of the present invention. For example, the battery module 1000 may include components such as a battery core and a controller connected to the battery core, and so on. These details are not explicitly described here.

[0142] As a preferred embodiment, in the embodiment of the present application, the battery module 1000 is detachably connected to the shell 800. This detachable connection allows for the recycling and processing of the battery module after the system is used, preventing pollution.

[0143] As a preferred embodiment, in the embodiment of the present application, the battery module 1000 is connected to the shell 800 through a connecting assembly (not shown in the figure). The battery module comprises a battery core set in the battery accommodating cavity and a bottom cover set at the bottom of the battery core (not shown in the figure). In a specific embodiment, the connecting assembly comprises mutually cooperating first and second connecting components. The first connecting component is set on the shell 800, and the second connecting component is set on the bottom cover. The first and second connecting components are detachably connected, thereby achieving a detachable connection between the battery module 1000 and the shell 800.

[0144] As a preferred embodiment, in the embodiment of the present application, the first connecting component and the second connecting component are snap-connected. Specifically, in one embodiment, one of the first connecting component and the second connecting component can be a connecting buckle, and the other can be a connecting hole that cooperates with the connecting buckle. In other words, the first connecting component can be a connecting buckle, and the second connecting component can be a connecting hole, or vice versa. It is understood that, to achieve a snap connection between the first connecting component and the second connecting component, the connecting buckle can be an elastic element. Alternatively, the portion of the outer shell or bottom cover connected to the connecting buckle (i.e., the connecting hole portion) can be an elastic element. Additionally, both the connecting buckle and the connecting hole can be elastic elements, allowing for a detachable connection between the connecting buckle and the connecting hole.

[0145] As a preferred embodiment, in the embodiment of the present application, the connection between the battery module 1000 and the shell 800 can also be achieved through threaded connection or adhesive bonding, without going into further details here.

[0146] As a preferred embodiment, in the embodiment of the present application, the aerosol system also comprises packaging material (not shown in the figure) and a cover body 1100. The packaging material wraps around the shell 800 and the external surface of the liquid storage compartment 300, while the cover body 1100 is fitted onto the end of the shell 800 away from the mouthpiece component 200. When it is necessary to detach the battery module 1000 from the outer shell 800, the cover body 1100 can be removed first, followed by the removal of the packaging material covering the shell 800 and the liquid storage compartment 300. Subsequently, pressing on the second connecting component causes it to disengage from the first connecting component, allowing the base cover to detach from the shell 800 and consequently removing the battery module from the shell 800.

[0147] Embodiment Three

[0148] The difference from Embodiment One lies in the placement of the air-cutting hole in the cigarette rod in this exemplary embodiment. Figure 8 is a structural schematic diagram of the cigarette device in the aerosol provision system provided in the embodiment of this application. Figure 9 is a sectional schematic diagram of the cigarette device in the aerosol provision system provided in the embodiment of this application. Referring to Figures 8 and 9, the cigarette device of this aerosol provision system generally comprises a cigarette device housing 1200, an air inlet passage (not shown in the figure), a battery module 1000, and an intercepting air hole 600.

[0149] The cigarette device housing 1200 has a battery containing chamber (not shown in the figure) for accommodating the battery module 1000. The intercepting air hole 600 is located at the top of the battery containing chamber, and the intercepting air hole 600 is in fluid communication with the air inlet passage, with the fluid flow at the intercepting air hole 600 being minimized in the air inlet passage. By placing the intercepting air hole at the top of the battery containing chamber and adjusting the fluid flow at the intercepting air hole to be minimal in the air inlet passage, the system achieves the regulation of the airflow entering the atomizing chamber through components other than the air inlet hole, allowing the cigarette rod to achieve the expected suction resistance.

[0150] As a preferred embodiment, in the embodiment of the present application, the intercepting air hole 600 is angularly positioned with respect to the longitudinal direction of the cigarette rod, preferably, the axial direction of the intercepting air hole 600 is perpendicular to the longitudinal direction of the cigarette device.

[0151] As a preferred embodiment, in the embodiment of the present application, the number and size of the intercepting air holes 600 are not specifically limited, and in specific implementations, they are set based on the expected suction resistance of the cigarette device. As an illustrative and non-limiting example, in this embodiment of the application, the number of intercepting air holes 600 comprises at least two, and at least two intercepting air holes 600 are circumferentially spaced along the longitudinal direction of the cigarette device.

[0152] In a specific embodiment, as shown in Figure 10, the cigarette device further includes a top cap 1300 located at the top of the battery containing chamber. The top cap 1300 is positioned to face the bottom of the cartridge when the cartridge is loaded, and the intercepting air hole 600 is set on the top cap 1300. Specifically, the top of the top cap 1300 (i.e., the end facing the cartridge) forms a cavity 1310, which is in communication with the atomization chamber (not shown in the figure). The intercepting air hole 600 is located at the top of the top cap 1300 near the end facing the cartridge, and the intercepting air hole 600 connects the cavity 1310 with the air inlet channel (not shown in the figure).

[0153] In another specific embodiment, the battery module comprises a top cap and a structural component set on the top cap. The structural component is positioned to face the bottom of the cartridge when the cartridge is loaded, and the intercepting air hole is set on the structural component. Specifically, the structural component forms a cavity in communication with the atomizing chamber, and the intercepting air hole 600 is located on the structural component. The intercepting air hole 600 connects the cavity with the air inlet channel (not shown in the figure).

[0154] Further referring to Figure 8, an air inlet 1400 is provided on the cigarette device housing 1200. The air inlet 1400 is in fluid communication with the intercepting air hole 600 through an air inlet channel, and on the other side, the air inlet 1400 connects the air inlet channel with the external environment, thereby allowing the intercepting air hole to communicate with the external environment. Referring further to Figure 7, the air inlet 1400 can be located on the circumferential surface of the cigarette device housing 1200, and along the transverse direction of the cigarette device, the air inlet 1400 and the intercepting air hole 600 are positioned in the same transverse plane.

[0155] As a preferred embodiment, in the embodiment of the present application, the battery module 1000 comprises a battery pack housing, the battery pack housing (not shown in the figure) is provided with a battery containing chamber inside, there is a third gap between the battery pack housing and the cigarette device housing 1200, and the third gap forms the air inlet channel.

[0156] As a preferred embodiment, in the embodiment of the present application, the intercepting air hole 600 extends along a direction perpendicular to the length direction of the cigarette device, i.e., transversely. There exists a fourth gap between a surface of the intercepting air hole, facing the side of the cigarette device housing 1200, and the cigarette device housing 1200. This fourth gap is in fluid communication with the air inlet channel, allowing gases from the air inlet channel to enter through this gap into the intercepting air hole.

[0157] As a preferred embodiment, in the embodiment of the present application, the cigarette device also comprises a packaging material 1500 wrapped around the circumferential surface of the cigarette device housing 1200. The packaging material 1500 is opened with a marking hole 1510. The cigarette device housing 1200 can be disassembled into two parts at the position of the marking hole 1510, and the air inlet 1400 coincides with at least a part of the marking hole 1510.

[0158] As a preferred embodiment, in the embodiment of the present application, in the projection of the air inlet 1400 in the axial direction, at least a portion of the marking hole is exposed inside the air inlet, allowing the marking hole to serve as an entry point for external atmosphere into the air inlet. By having at least a portion of the marking hole exposed inside the air inlet, it facilitates the rupture of the packaging material during the disassembly of the cigarette device housing, making the disassembly convenient. Additionally, it allows the marking hole to serve as a communication hole between the air inlet set on the packaging material and the external atmosphere.

[0159] As a preferred embodiment, in the embodiment of the present application, the surface where the intercepting air hole 600 is located is also provided with a containing trough 1600. The containing trough is formed by the top cover, concaving from the outer wall to the inner wall of the top cap. The trough mouth of the containing trough 1700 faces the cigarette device housing 1200, and the intercepting air hole 600 is arranged on the bottom wall of the containing trough 1600. Preferably, the width of the containing trough is greater than the dimension of the marking hole 1510 in the width direction of the containing trough 1600. Additionally, the width of the trough mouth of the containing trough 1600 is greater than the width of the trough bottom of the containing trough 1600, allowing gas to smoothly enter the intercepting air hole through the containing trough. The number of containing troughs comprises multiple ones, with the multiple containing troughs spaced apart on the top cap.

[0160] As a preferred embodiment, in the embodiment of the present application, the marking holes comprise multiple ones, and in the projection of the marking holes in the axial direction, the plurality of marking holes is exposed in the containing trough 1600. By arranging multiple marking holes in this way, when the aerosol system is held by the user, if certain marking holes are accidentally covered by fingers, external gas can still enter the containing trough through the remaining unobstructed marking holes.

[0161] In the embodiment of this application, there is no specific limitation on the specific composition of the battery component 1000. Any known battery component can be used in this embodiment without departing from the conceptualization of the present invention. For example, the battery component 1000 may include components such as a battery core and a controller connected to the battery core, and so on. These details are not explicitly described here.

[0162] Embodiment Four

[0163] Referring to Figures 12 and 13, corresponding to the embodiment three mentioned above, the present application also provides an aerosol provision system. The system comprises the cigarette device and cartridge as described in any one of the embodiment three. In this system, the cigarette device housing 1200 is provided with a receiving chamber (not shown in the figure) located at the top of the battery containing chamber for inserting the cartridge. The cartridge is at least partially inserted into the receiving chamber, and the cartridge is equipped with an air passage 500. The air passage 500 is in fluid communication with the air inlet channel through the intercepting air hole 600. In this embodiment, content that is the same or similar to the embodiment three mentioned above can be referred to in the previous introduction and will not be repeated here.

[0164] As a preferred embodiment, in the embodiment of the present application, the fluid flux at the intercepting air hole 600 is the smallest in the air passage 500 and the air inlet channel, thereby achieving the regulation of the final airflow entering the atomizing chamber through components other than the air inlet hole. This allows the aerosol system to achieve the expected suction resistance.

[0165] It is understood that, in the embodiment of this application, the cartridge also comprises the cartridge housing 100, mouthpiece component 200, liquid storage compartment 300', and atomizing core 400'. Inside the cartridge housing 100, there is formed a containing space, atomizing chamber 410, and air passage 500. The atomizing chamber 410 is in fluid communication with the air passage 500. Components such as the liquid storage compartment 300' and atomizing core 400' are set or at least partially set within the containing space. The atomizing core 400' comprises an atomizing chamber 410 for accommodating a heater. In this embodiment, there is no specific limitation on the cartridge housing 100 and mouthpiece component 200, and they can be selected or set according to the actual product requirements without deviating from the conceptual basis of the invention of this application.

[0166] As a preferred embodiment, in the embodiment of the present application, the air passage 500 has an upright portion at least within the atomizing chamber 410 along the length direction of the cartridge. In other words, at least a portion of the air passage 500 is vertically oriented along the length direction of the cartridge. It can be understood that the orientation of some portions of the air passage 500 can be adaptively adjusted based on the internal structure of the cartridge. For example, they may be set along a direction perpendicular to the length direction of the cartridge or have a curved shape, and so on. These details are not elaborated here.

[0167] Figure 14 is a structural schematic diagram of the liquid storage structure provided in embodiment 4 of this application. As shown in Figure 14, in this embodiment, the liquid storage compartment 300' is set in the cartridge housing 100. The liquid storage compartment 300' includes an oil-absorbing body 310' and a hollow tube body 320'.
