Description

Technology Field

[0001] The present invention relates to the field of aerosol delivery, and in particular to an aerosol delivery device and an aerosol delivery system. Background Technology

[0002] Electronic cigarette-type aerosol delivery systems, which heat but do not burn aerosol-generating materials containing aerosol-forming substrates (such as cigarettes), generally use heaters or similar devices to heat the aerosol-generating materials to a sufficiently high temperature to generate aerosols for user puffing. Aerosol delivery systems typically use batteries to power the heaters. If the aerosol is exposed to cold, it will produce condensation. If this condensation is not properly collected and treated, on the one hand, it tends to accumulate in the atomization chamber, causing users to puff condensation along with the aerosol during puffing, thereby affecting the user's puffing experience. On the other hand, if the condensation comes into contact with components such as batteries, it can cause damage to these components in the field of electronic cigarette technology.

[0003] Therefore, there is an urgent need for a new structure for an aerosol delivery system to solve one or more of these technical problems.

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. Accordingly, the present invention discloses an aerosol dispensing device and an aerosol dispensing system for solving the technical problems of a method for properly collecting and processing condensate and preventing the accumulation of condensate in a vaporization chamber, which affects the user's inhalation experience by causing users to inhale condensate along with the aerosol during puffing. Additionally, the invention solves a method for preventing condensate from coming into contact with components such as batteries, thereby avoiding damage to components such as batteries.

[0005] In a first aspect, the present invention discloses an aerosol providing device, wherein the device comprises at least a battery-containing chamber and a battery top cap located on the top of the battery-containing chamber, wherein the battery top cap is formed to have a first cavity inside, the first cavity is in fluid communication with an air flow channel of the device, and the battery top cap has a top surface and a bottom surface arranged continuously along the height direction of the device, wherein a first electrode hole is open on the top surface, the first cavity is formed between the top surface and the bottom surface, and a first opening is provided on the top surface.

[0006] In an embodiment of the present invention, a first cavity is formed on a battery top cover located at the top of a battery compartment and configured to fluidly communicate with an air flow channel of the device, thereby allowing condensate to be collected through the first cavity. On the one hand, this prevents the condensate from accumulating in the atomization chamber, thereby avoiding users inhaling the condensate along with the aerosol during puffing, thus preserving the user's puffing experience. On the other hand, it prevents the condensate from coming into contact with components such as the battery, thereby avoiding damage to the battery and other components.

[0007] In a technical solution for an aerosol delivery system, the battery top cap is additionally formed to have a functional chamber for containing a control device;

[0008] In the transverse direction of the device, the projection of the first cavity overlaps with the projection of the functional chamber.

[0009] In a technical solution for an aerosol delivery system, the control device includes an air flow sensor, and a through hole is opened in the side wall of a first cavity near a functional chamber, and the air flow sensor is arranged at one end of the through hole away from the first cavity, and the first cavity is fluidly in communication with the air flow sensor through the through hole, so that the first cavity is formed as a negative pressure chamber.

[0010] By configuring the first cavity to function as a negative pressure chamber, the top cover of the battery achieves both leak prevention and negative pressure chamber functions, thereby reducing the overall size of the device.

[0011] In the technical solution of the aerosol delivery system, the through hole has a predetermined distance from the lowest wall of the first cavity.

[0012] By establishing a predetermined distance between the through hole and the lowest wall of the first cavity, condensate from the lowest wall of the first cavity is prevented from entering the through hole and causing damage to the air flow sensor.

[0013] In the technical solution of the aerosol delivery system, a through hole is provided with a one-way valve or a waterproof breathable membrane inside the through hole.

[0014] Setting a one-way valve or a waterproof breathable membrane in the through hole is more helpful in preventing condensation from the bottom wall of the second cavity from entering the through hole and causing damage to the air flow sensor.

[0015] In a technical solution for an aerosol delivery system, the battery top cap is additionally formed to have a second cavity fluidly communicating with the first cavity, and the top surface is formed as the bottom wall of the second cavity.

[0016] In a technical solution for an aerosol delivery system, the second cavity comprises a first part and a second part fluidly communicating with each other, and the second part extends toward a battery-containing chamber along the lowest wall of the first part.

[0017] In a technical solution for an aerosol delivery system, a first cavity and / or a second cavity is provided with a first collecting groove inside, and the first collecting groove is formed on the lowest wall of the first cavity and / or the second cavity and extends along the transverse direction of the device.

[0018] By setting a first collection groove inside the first cavity and / or the second cavity, the first collection groove adsorbs a portion of the condensate, thereby further enhancing the leak prevention effect.

[0019] In the technical solution of the aerosol delivery system, there are multiple first collection grooves.

[0020] In the technical solution of an aerosol delivery system, the width of the groove opening of the first collection groove is greater than the width of the lowest part of the groove of the first collection groove.

[0021] By configuring the first collection groove so that the width at the inlet is greater than the width at the bottom, the condensate is facilitated to enter the first collection groove.

[0022] In a technical solution for an aerosol delivery system, the width of the first collection groove gradually decreases from the groove opening of the first collection groove to the bottom of the first collection groove.

[0023] In the technical solution of an aerosol delivery system, the first collecting groove is a capillary groove.

[0024] In a technical solution for an aerosol delivery system, the first collecting groove has a groove width of 0.2 to 0.5 mm and a groove depth of 0 to 10 mm.

[0025] In a technical solution for an aerosol delivery system, a first cavity is additionally provided with a second collecting groove inside, and the second collecting groove is formed on the side wall of the first cavity and extends along the longitudinal direction of the device.

[0026] By placing a second collection groove on the side wall of the first cavity, the adsorption capacity of the aerosol system for condensate is increased, thereby further enhancing the leakage prevention effect of the system. This helps prevent condensate from causing damage to the battery components.

[0027] In a technical solution for an aerosol delivery system, one end of the second collection groove is in fluid communication with one end of the first collection groove arranged on the lowest wall of the first cavity.

[0111] This disclosure relates to aerosol delivery systems (which may also be referred to as vapor delivery systems), such as atomizers or e-cigarettes. Throughout the following description, the terms "e-cigarette" or "electronic cigarette" may be used from time to time, but it will be recognized that these terms may be used interchangeably with aerosol delivery systems / devices and electronic aerosol delivery systems / devices. Additionally, as is common in the art, the terms "aerosol" and "vapor," and related terms such as "vaporize," "volatilize," and "aerosolize" may generally be used interchangeably.

[0112] Aerosol delivery systems (e-cigarettes) often, but not always, comprise a modular assembly that includes a reusable device part and a replaceable (disposable / consumable) cartridge part. Often, the replaceable cartridge part will include aerosol-generating material and a vaporizer (collectively referred to as a "cartomizer"), and the reusable device part will include a power supply (e.g., a rechargeable power source) and control circuitry. It will be recognized that these different parts may include additional elements depending on their function. For example, the reusable device part will often include a user interface for receiving user input and displaying operating status characteristics, and the replaceable cartridge device part will include a temperature sensor to help control the temperature in some cases. The cartridges are electrically and mechanically coupled to the control unit for use, for example, using screw threads, bayonets, or magnetic couplings with appropriately arranged electrical contacts. When the aerosol generating material in the cartridge is depleted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable part and a replacement cartridge can be 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.

[0113] It is common for electronic cigarettes to generally have an elongated shape. To provide a specific example, certain embodiments of the disclosure will be considered to include a two-part system of this kind, which is generally elongated, using disposable cartridges. However, it will be recognized that the basic principles described herein may be equally applied to different configurations, e.g., single-part systems or modular systems comprising more than two parts, rechargeable devices, and single-use disposables, as well as other overall shapes, e.g., so-called box-mode high-performance devices, which generally have a more boxy shape. More generally, certain embodiments of the disclosure are based on aerosol delivery systems operably configured to provide functions according to the principles described herein, and it will be recognized that the constitutive aspects of the systems configured to provide functions according to the specific embodiments of the disclosure are of no significant importance.

[0114] As mentioned in the technical background, if condensate is not properly collected, on the one hand, it can easily accumulate in the atomization chamber, causing users to inhale the condensate along with the aerosol during puffing, which can affect the user's puffing experience. On the other hand, if the condensate comes into contact with components such as batteries, it can cause damage to these components. Based on this, the present application discloses a novel cartridge for an aerosol delivery system aimed at preserving the user's puffing experience by preventing the inhalation of condensate by users during puffing. At the same time, it also serves to avoid damage to components such as batteries by preventing the condensate from coming into contact with them.

[0115] Specific details of embodiments of the present application will be described with reference to the attached drawings.

[0116] Embodiment 1

[0117] FIG. 1 is a schematic diagram of the three-dimensional structure of an aerosol providing device after removing the device housing of the aerosol providing device described in Embodiment 1 of the present application. FIG. 2 is a schematic diagram of the structure of the battery top cap of the aerosol providing device described in Embodiment 1 of the present application. Referring to FIG. 1 and FIG. 2, in an embodiment of the present application, the aerosol providing device generally comprises a battery storage compartment (not shown in the drawings), a battery top cap (100), a battery component (200), and a device housing (300). The device housing (300) forms the aforementioned battery storage compartment inside, and the battery component (200) is placed in the battery storage compartment. The device housing (300) also forms a receiving space for receiving the battery top cap (100), thereby enabling the installation of the battery top cap (100). The battery top cap (100) is located on the top of the battery storage compartment.

[0118] Referring further to FIG. 2, in a specific embodiment, the battery top cap (100) forms a first cavity (110) and a second cavity (120). The first cavity (110) is in fluid communication with the second cavity (120). The first cavity (110) is connected to an air flow channel (not shown in the drawing) of the device, and the battery top cap (100) has a top surface (130) and a bottom surface (140) arranged in the height direction of the device. The top surface (130) has a first electrode hole (150), and the first cavity (110) is formed between the top surface (130) and the bottom surface (140). The top surface (130) forms the bottom wall of the second cavity (120), and the top surface has a first opening (160). The design of the present application enables the collection of condensate through the first cavity. On the one hand, it is prone to accumulating in the atomization chamber, causing users to puff condensate along with the aerosol during puffing, which affects the user's puffing experience. On the other hand, if the condensate comes into contact with components such as batteries, it can cause damage to these components in the field of electronic cigarette technology.

[0119] In another specific embodiment, the device further includes an air flow sensor (not shown in the drawing). The battery top cap (100) forms a first cavity (110) and a second cavity (120) inside, and the first cavity (110) is in fluid communication with the second cavity (120). The first cavity (110) is connected to an air flow channel (not shown in the drawing) of the device, and the battery top cap (100) has a top surface (130) and a bottom surface (140) arranged in the height direction of the device. The first cavity (110) is formed between the top surface (130) and the bottom surface (140), and the top surface (130) forms the bottom wall of the second cavity (120). The first cavity (110) is connected to an air flow sensor, so that the first cavity forms a negative pressure chamber, thereby reducing the overall size of the device.

[0120] In a preferred embodiment, in an embodiment of the present application, the system also includes a controller component (not shown in the drawing). Preferably, the battery top cap (100) is further formed to have a function chamber (170) for including a control device. Referring further to FIG. 2, in the transverse direction of the device, the projection of the first cavity (110) overlaps with the projection of the function chamber (170).

[0121] It can be understood that the controller component includes at least an air flow sensor (not shown in the drawing). A through hole (111) is opened on the side wall of the first cavity (110) near the function chamber (170), and the air flow sensor is positioned at the end of the through hole (111) away from the first cavity (110). This configuration allows the first cavity (110) to communicate with the air flow sensor through the through hole (111), thereby creating a negative pressure chamber. Functions related to the negative pressure chamber may be referenced in the prior art and are not described in further detail here. In this embodiment, by setting the first cavity (110) as a negative pressure chamber, the battery top cap (100) achieves both leak prevention and negative pressure chamber functions, thereby reducing the overall structure of the system.

[0122] In a preferred embodiment, in an embodiment of the present application, setting a predetermined distance between the through hole (111) and the lowest wall of the first cavity (110) is intended to prevent condensation from the lowest wall of the first cavity (110) from entering the through hole and causing damage to the air flow sensor. It may be understood that, where product design permits, a larger distance between the through hole and the lowest wall of the first cavity is preferable.

[0123] In a preferred embodiment, in an embodiment of the present application, a one-way valve or a waterproof breathable film is installed in the through hole (111) to further prevent condensation from the lowest wall of the first cavity (110) from entering the through hole and causing damage to the air flow sensor.

[0124] Referring further to FIG. 2, in an embodiment of the present application, a first cavity (110) and / or a second cavity (120) is provided with a first collection groove (112) inside, the first collection groove (112) is formed on the bottom wall of the first cavity (110) and / or the second cavity (120) and extends along the transverse direction of the device. By using the first collection groove (112) to adsorb condensate entering the first cavity (110) and / or the second cavity (120), the adsorption capacity of the device for condensate is increased, thereby further enhancing the leak prevention effect of the device.

[0125] Preferably, there are multiple first collection grooves.

[0126] Preferably, by configuring the groove opening of the first collection groove (112) to be larger than the width of the lowest part of the groove of the first collection groove (112), the condensate is facilitated to enter the first collection groove.

[0127] In a specific embodiment, the width of the first collection groove (112) is set to gradually decrease from the groove opening of the first collection groove to the bottom of the groove of the first collection groove (112).

[0128] In another specific embodiment, the first collecting groove (112) is configured to consist of a plurality of sections in which the groove width of the plurality of sections gradually decreases along the direction from the groove opening to the bottom of the groove.

[0129] Preferably, the first collection groove is a capillary groove. It can be understood that capillary grooves have a specific adsorption capacity for liquids due to their inherent properties. Using capillary grooves as the first collection grooves can enhance their adsorption capacity for condensates.

[0130] In a specific embodiment, the groove width of the first collecting groove is any value within the range of 0.2 to 0.5 mm, such as 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc. The groove depth is any value within the range of 0 to 10 mm, such as 0.5 mm, 1 mm, 2 mm, 5 mm, 10 mm, etc. Here, not all values ​​are listed comprehensively.

[0131] To further improve the adsorption capacity of the condensate, in a preferred embodiment, in an embodiment of the present application, the first cavity (110) also includes a second collection groove (113) within the first cavity (110). In a specific embodiment, the second collection groove (113) is positioned on the side wall of the first cavity (110) and extends along the longitudinal direction of the device.

[0132] Preferably, the end of the second collection groove (113) is connected to one end of the first collection groove (112) positioned on the lowest wall of the first cavity (110). This arrangement facilitates the flow of condensate along the second collection groove (113) into the first collection groove (112) and adsorption by the first collection groove (112).

[0133] Preferably, the second collection groove (113) is a capillary groove. It can be understood that a capillary groove has a specific adsorption capacity for liquids due to its inherent properties. Using a capillary groove as the second collection groove (113) can improve its ability to adsorb condensate.

[0134] In the embodiments of the present application, there are no specific limitations on the specific configuration of the battery component (200). Any known battery component may be used in the embodiments without departing from the conceptualization of the present invention. For example, the battery component (200) may include components such as a battery core and a controller connected to the battery core. These details are not explicitly described herein.

[0135] Embodiment 2

[0136] The difference from embodiment 1 is that in the embodiment of the present application, as shown in FIG. 3, the second cavity (120') comprises an interconnected first part (114) and a second part (115), wherein the second part (115) extends toward the battery compartment along the lowest wall of the first part (114).

[0137] It can be understood that by setting the second cavity (120') to interconnect the first part (114) and the second part (115), the receiving space of the second cavity (120') can be increased, thereby allowing it to hold more condensate.

[0138] Embodiment 3

[0139] Corresponding to embodiments 1 and 2, embodiments of the present application disclose an aerosol delivery system as illustrated in FIGS. 4 and 5. This includes a cartridge and an aerosol delivery device as described in either embodiment 1 or 2. The cartridge generally includes an atomizing core (400), a first leak-proof unit (500), a mouthpiece component (700), a liquid storage compartment (800), a cartridge housing (900), and an air inlet (1000). Inside the cartridge housing (900) there is a storage space and an air flow channel. Part of the storage space forms an atomizing chamber (410), and another part of the storage space is used to set or partially set the atomizing core (400), the first leak-proof unit (500), and the liquid storage compartment (800). The air inlet (1000) connects the air flow channel (not labeled in the drawings) to the external atmosphere of the aerosol delivery system. The atomizing chamber (410) is fluidly connected to the air inlet and the outlet of the mouthpiece component (700) through an air flow channel, allowing the aerosol to be inhaled by the user from the outlet of the mouthpiece component (700). A first leak prevention unit (500) is set upstream along the direction of air flow in the atomizing chamber (410) to adsorb condensate. On the one hand, it prevents the accumulation of condensate in the atomizing chamber, thereby avoiding users inhaling condensate along with the aerosol during puffing, thus preserving the user's puffing experience. On the other hand, it prevents the condensate from coming into contact with components such as batteries, thereby avoiding damage to components such as batteries.

[0140] In an embodiment of the present application, it may be understood that the air flow direction refers to the direction in which external air enters the air flow channel through the air inlet and sequentially passes through the first leak prevention unit (500), the atomizing chamber (410), and the mouthpiece component (700).

[0141] FIG. 6 is an exploded view of the first leak prevention described in Embodiment 3 of the present application. As shown in FIG. 6, in an embodiment of the present application, the first leak prevention unit (500) comprises a third cavity (510), a first holder (520), and a liquid absorption member (530). The third cavity (510) is configured to be located near the atomizing chamber (410) and upstream of the atomizing chamber (410) along the direction of air flow. The first holder (520) is configured to have a first bottom surface (521) forming the bottom of the third cavity (510) and a first air vent pipe (522) extending from the first bottom surface (521) into the third cavity (510). A liquid absorbing member (530) is positioned within a third cavity (510) and has a pass hole (531), wherein the pass hole (531) is configured to allow a first air vent pipe (522) to pass through, and the uppermost surface of the pass hole (531) is not lower than the uppermost surface of the first air vent pipe (522). It can be understood that when condensation occurs due to the cooling of the aerosol generated in the atomizing chamber, the liquid absorbing member (530) located in the third cavity (510) adsorbs the condensate. This prevents the condensate from accumulating in the atomizing chamber, thereby avoiding a situation where the user inhales the condensate along with the aerosol during puffing, and thus prevents it from affecting the user's puffing experience. Additionally, it prevents the condensate from coming into contact with components such as batteries, thereby preventing damage to these components. Setting the uppermost surface of the passage hole (531) so that it is not lower than the uppermost surface of the first air vent pipe (522) causes the liquid absorbing member to absorb more condensate and reduces the amount of condensate falling down through the first air vent pipe (522).

[0142] Referring further to FIG. 6, the first holder (520) also includes a first circumferential wall (523) surrounding the circumferential surface of the third cavity (510) and a second electrode hole (524) open on the first bottom surface (521). The second electrode hole (524) is designed to allow the passage of electrodes. It can be understood that there are two second electrode holes (524), each allowing the passage of an anode and a cathode, respectively.

[0143] FIG. 7 is a schematic diagram of the structure of the first holder of the first leak prevention unit described in Embodiment 3 of the present application. As illustrated in FIG. 7, in a preferred embodiment, in the embodiment of the present application, there are also air blocking holes (525) on the first holder (520) that are open at one end of the first holder (520) away from the third cavity (510). The air blocking holes (525) form part of an air flow channel, and the volume of air flow in the air flow channel is minimized at the location of the air blocking holes (525). In a specific implementation, the axial direction of the air blocking holes (525) is set to be at an angle with respect to the longitudinal direction of the cartridge. Preferably, the axial direction of the air blocking holes (525) is orthogonal to the longitudinal direction of the cartridge. The number of air blocking holes (525) includes at least two, and the at least two air blocking holes are evenly spaced along the circumferential direction of the first holder (520). The air blocking holes (525) extend in a direction perpendicular to the longitudinal direction of the cartridge, and there is a gap between the surface of the air blocking holes (525) facing the side of the cartridge housing and the cartridge housing to allow gas to pass through.

[0144] In order for the liquid absorbing member (530) to adsorb as much condensate as possible and prevent the accumulation of condensate on the sidewalls of the third cavity (510), as a preferred embodiment, in this embodiment of the present application, the height of the liquid absorbing member (530) in the depth direction of the third cavity (510) is not less than the depth of the third cavity (510). Preferably, the uppermost surface of the liquid absorbing member (530) is at the same height as the uppermost part of the third cavity (510). Additionally, preferably, the liquid absorbing member (530) is set to fill the third cavity (510) to ensure that the liquid absorbing member can adsorb as much condensate as possible and prevent the accumulation of condensate on the sidewalls of the third cavity. It should be noted that the specific material of the liquid absorbing member is not limited in this embodiment. Any material capable of adsorbing liquid may be used as the liquid absorbing member in this application as long as it can adsorb liquid without violating the conceptual framework of the present invention. As an exemplary example rather than a limiting one, the liquid absorbent member in the present embodiment may be made of materials such as cotton.

[0145] Referring further to FIG. 6, the first leak prevention unit in this embodiment of the present application also includes a sealing member (540). The sealing member (540) is located at the top of the first holder (520) and covers the opening of the third cavity (510). The sealing member (540) has an opening (541), which connects the third cavity (510) to the atomizing chamber (410). In specific embodiments, the sealing member (540) and the first holder (520) may be connected by a buckle, for example, a connecting buckle (526) is set on the first holder (520), and a connecting hole (542) is provided on the sealing member (540). The connection between the sealing member (540) and the first holder (520) is achieved through the connecting buckle (526) and the connecting hole (542). By placing a sealing member on the uppermost part of the first holder, it is possible to prevent the condensate from leaking out of the opening of the third cavity when there is excessive condensate in the third cavity.

[0146] As can be understood, in order to enable the passage of electrodes, the sealing member (540) may have a third electrode hole (543). The third electrode hole (543) includes two, each allowing a positive electrode and a negative electrode to pass through.

[0147] In a preferred embodiment, in an embodiment of the present application, the first leak prevention unit (500) further includes a fourth collection groove (not shown in the drawing). The fourth collection groove (not shown in the drawing) is positioned on the lowest wall of the third cavity (510) and extends along the transverse direction of the cartridge shell. By setting the fourth collection groove on the lowest wall of the third cavity, it is possible to further improve the leak prevention effect by adsorbing a portion of the condensate using the fourth collection groove.

[0148] Preferably, the width of the opening of the fourth collection groove is greater than the width of the lowest part of the fourth collection groove. This facilitates the entry of condensate into the fourth collection groove.

[0149] Preferably, the number of fourth collection grooves may be multiple.

[0150] Preferably, the fourth collection groove is a capillary groove. It can be understood that capillary grooves have a specific adsorption capacity for liquids due to their inherent properties. Using a capillary groove as the fourth collection groove can enhance its ability to adsorb condensate.

[0151] In a preferred embodiment, in an embodiment of the present application, the aerosol supply system further includes a second leak prevention unit (600). The second leak prevention unit (600) is arranged along the direction of air flow between the battery top cap (100) and the first leak prevention unit (500). By arranging the second leak prevention unit along the direction of air flow between the battery top cap and the first leak prevention unit, the adsorption capacity of the system for condensate is increased, thereby further enhancing the leak prevention effect of the cartridge.

[0152] The second leak prevention unit (600) is positioned upstream of the first leak prevention unit (500) along the direction of air flow. Referring to FIG. 8, in an embodiment of the present application, the second leak prevention unit (600) generally includes a fourth cavity (610), a second holder (620), and a third collection groove (630). The fourth cavity (610) is configured to be in fluid communication with the third cavity (510) through the first air vent pipe (522), so that a fluid containing condensate enters the fourth cavity (610) from the third cavity (510) through the first air vent pipe (522). The second holder (620) is configured to have a second bottom surface (621) forming the bottom of the fourth cavity (610) and a second air vent pipe (622) extending from the second bottom surface (621) into the fourth cavity (610). The third collection groove (630) is configured to be located on the second bottom surface (621) and extend laterally along the cartridge. By positioning the second leak prevention unit upstream along the air flow direction from the first leak prevention unit, the second collection groove (630) adsorbs condensate entering the fourth cavity from the third cavity, thereby increasing the adsorption capacity of the cartridge for condensate and further improving the leak prevention effect of the cartridge.

[0153] In a preferred embodiment, in an embodiment of the present application, the centerline of the second air vent pipe (622) is intentionally offset from the centerline of the first air vent pipe (522). This configuration ensures that the air flow path between the atomizing chamber and the third cavity is offset from the air flow path between the third cavity and the fourth cavity. The intentional offset increases the path for condensate to travel from the atomizing chamber through the third cavity and the fourth cavity. This design maximizes the adsorption of condensate by the first and second leak-prevention units, thereby enhancing the leak-prevention effect.

[0154] Preferably, the uppermost surface of the second air vent pipe (622) is positioned higher than the uppermost surface of the third collection groove (630). This arrangement is intended to prevent condensate from the third collection groove (630) from leaking through the second air vent pipe (622) and reaching below the second holder (620), thereby avoiding contamination or damage to the components located below.

[0155] Preferably, the third collection grooves (630) may be numerous.

[0156] In a specific embodiment, a plurality of third collection grooves (630) are not interconnected.

[0157] In another specific embodiment, a plurality of third collection grooves (630) are interconnected, and nearby third collection grooves (630) are set to be angled to increase the adsorption capacity for condensate in the third collection grooves (630).

[0158] Preferably, the width of the opening of the third collection groove (630) is greater than the width of the bottom of the third collection groove (630) to facilitate the entry of condensate into the third collection groove.

[0159] Preferably, the third collection grooves are capillary grooves. It can be understood that capillary grooves have a specific adsorption capacity for liquids due to their inherent properties. Using capillary grooves as the third collection grooves can enhance their adsorption capacity for condensates.

[0160] It can be understood that, for the convenience of electrode penetration, the second holder (620) is also provided with a fourth electrode hole (623). Preferably, the edge of the fourth electrode hole (623) contacts the bottom of the first holder (620). By setting the edge of the fourth electrode hole to contact the bottom of the first holder, contamination of the electrodes by fluids such as condensate can be avoided. Additionally, fluids such as condensate are prevented from flowing into the battery component through the electrode hole, thereby preventing damage to the battery component.

[0161] In a preferred embodiment, in an embodiment of the present application, the second holder (620) is designed as a sealing member and is used to seal the lowest space of the first holder (520). This configuration not only prevents condensate from leaking from the fourth cavity (610) when there is an excessive amount, but also forms a relatively sealed space at the lowest part of the first holder (520). This minimizes fluid flow through the air blocking hole, thereby facilitating a reduction in fluid flux in the air blocking hole in the air flow channel.

[0162] It can be understood that the second holder (620) is positioned to cover the end of the first holder (520) separated from the third cavity (510). To enhance the sealing effect, the second holder is set to have an interference fit with the first holder. As an exemplary example rather than a limiting description, the second holder may be made of silicone material.

[0163] FIG. 9 is a schematic diagram of the liquid storage compartment structure described in Embodiment 3 of the present application. As illustrated in FIG. 9, the internal structure of the liquid storage compartment (800) forms a liquid storage chamber (810) intended to accommodate aerosol-generating materials such as e-liquid. Inside the atomizing core (400), there is an atomizing chamber (410) designed to accommodate a heating element. The atomizing chamber (410) is fluidly connected to the liquid storage chamber (810) to allow the aerosol-generating material within the liquid storage chamber (810) to enter the atomizing chamber (410), be heated by the heating element, and then form an aerosol. In a preferred embodiment, in the embodiment of the present application, the liquid storage compartment (800) includes an outer wall (820). The outer wall (820) of the liquid storage compartment (800) may be formed integrally with the cigarette shell (900), meaning that the outer wall (820) constitutes part of the cigarette shell (900). Alternatively, the outer wall (820) and the cigarette shell (900) may be independent components. In a specific implementation, the outer wall (820) and the cigarette shell (900) are independent components, and the outer wall (820) covers the outside of the atomizing core (400). The liquid storage chamber (810) is collectively surrounded by the outer wall (820) and part of the surface of the atomizing core (400). Thus, along the height direction of the aerosol delivery system, the liquid storage chamber (810) is positioned over the atomizing core (400) and the atomizing chamber (410).

[0164] FIG. 10 is a schematic diagram of the structure of an atomizing core described in Embodiment 3 of the present application. As illustrated in FIG. 10, the atomizing core comprises a heater, an atomizing chamber for housing the heater, a first fixing component (420), a second fixing component (430) for fixing the heater, and an airway silicone component (440).
