Description

Technology Field

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

[0002] An aerosol delivery system refers to a system that holds aerosol-generating materials and generates aerosols for user puffs by heating, rather than burning, the aerosol-generating materials (such as cigarettes).

[0003] An aerosol delivery system generally includes a housing, a retention chamber within the housing, a cartomizer, a power source, and a controller. The retention chamber serves to hold the aerosol-generating material. The cartomizer includes an atomization chamber and a heater assembly located within this chamber, and the heater assembly includes a heating body and an oil-guide body. The oil-guide body receives the liquid aerosol-generating material (e.g., e-liquid) from the retention chamber and transfers it to the heating body. Powered by the power source under the management of the controller, the heating body heats the aerosol-generating material to generate an aerosol.

[0004] A commonly used heater assembly features a heating body and an oil guide body in a stacked arrangement. The heating body is a net formed of heating wires. These wires have a contact surface that contacts the oil guide body and a vaporization surface located away from it. The aerosol-generating material absorbed by the contact surface must be efficiently transferred to the vaporization surface for aerosol generation. FIG. 1 illustrates a cross-section of a heating wire, which is typically rectangular and features a contact surface (11) and three vaporization surfaces (12, 13, 14). The material on the contact surface (11) must traverse two bends (marked A and B in the drawing) to reach the entire vaporization surface (all three surfaces). The slow movement of the material in these bends, along with the multiple bends between the vaporization surfaces, results in a reduced oil-guiding rate across the entire vaporization surface of the heating wire. As a result, the material on the contact surface may not be immediately transferred to the entire vaporization surface, potentially causing dry burning and failure of the vaporization surface of the heating wire.

[0005] Therefore, a new heater assembly and aerosol delivery system are urgently needed to solve one or more of these technical problems.

[0006] The present invention solves at least one of the technical problems existing in the prior art. Accordingly, the present invention introduces a heater assembly for an aerosol supply system designed to solve problems such as the low oil transfer rate of the atomizing surface of the heating wire, which can cause dry burning failure in the prior art.

[0007] A first aspect of an embodiment of the present invention discloses a heater assembly for an aerosol supply system, wherein the heater assembly for an aerosol supply system comprises: an oil guide body configured to absorb an aerosol generating material; a heating body having a heating wire, wherein the heating wire contacts the oil guide body and heats the aerosol generating material, and at least a portion of the heating wire along the circumferential direction of the cross section has contact surfaces and vaporization surfaces that are successively connected end-to-end to form a closed loop, wherein the contact surfaces contact the oil guide body to receive the aerosol generating material absorbed by the oil guide body and to transfer it to the vaporization surfaces; and the heating wire comprises up to two of the vaporization surfaces.

[0008] Having up to two vaporization surfaces on the heating wire allows the aerosol-generating material on the contact surface of the heating wire to pass through up to two vaporization surfaces for complete delivery across the entire vaporization surface. This design improves the oil guide rate and reduces the occurrence of dry burns on the vaporization surfaces of the heating wire.

[0009] In one embodiment of a heater assembly for an aerosol delivery system, each of the vaporization surfaces does not have bend angles. The aerosol generating material on the contact surface of the heating wire passes through at most one bend angle or no bend angle at all to complete delivery across the entire vaporization surface, thereby improving the oil guide rate and reducing dry burn failures.

[0010] In one embodiment of a heater assembly for an aerosol delivery system, the heating wire includes a vaporization surface that forms a closed loop with the ends of the contact surface, and the vaporization surface is curved. The fact that the entire vaporization surface of the heating wire is curved without bends allows the aerosol generating material on the contact surface to be delivered across the entire vaporization surface without passing through any bends, thereby further improving the oil guide rate and reducing dry burn failures.

[0011] In one embodiment of a heater assembly for an aerosol delivery system, the curved surface is either an S-shaped surface or a partially cylindrical surface.

[0012] In one embodiment of a heater assembly for an aerosol delivery system, the heating wire comprises a first vaporization surface and a second vaporization surface, and the contact surface, the first vaporization surface, and the second vaporization surface are connected end to end in a continuous manner to form a closed loop.

[0013] In one embodiment of a heater assembly for an aerosol delivery system, the joint between the first vaporization surface and the second vaporization surface does not have bending angles. This design allows the aerosol generating material on the contact surface to complete its delivery across the entire vaporization surface without passing through any bending angles, thereby further improving the oil guide rate and reducing dry burn failures.

[0014] In one embodiment of a heater assembly for an aerosol delivery system, the joint between the first vaporization surface and the second vaporization surface forms a bending angle.

[0015] In one embodiment of a heater assembly for an aerosol supply system, first and second vaporization surfaces on a cross-section have a first side at the junction of the first and second vaporization surfaces and a second side connected to a contact surface, and the distances from the first side to the second side are the same on both the first and second vaporization surfaces. This ensures that aerosol generating material from both ends of the contact surface reaches the bending angle simultaneously, thereby preventing it from passing through the bending angle and further improving the oil transfer rate.

[0016] In one embodiment of a heater assembly for an aerosol delivery system, the cross-sectional shape of the first and second vaporization surfaces is axially symmetric, and the axis of symmetry passes through the junction of the first and second vaporization surfaces and is perpendicular to the contact surface. This symmetry ensures that the path of the aerosol generating material delivered from both ends of the contact surface to the junction of the two vaporization surfaces is the same, so that it reaches the junction simultaneously. Even if the connection point of the two vaporization surfaces forms an angle, the aerosol generating material does not need to pass through this angle, thereby further improving the oil transfer rate.

[0017] In one embodiment of a heater assembly for an aerosol delivery system, the first and second vaporization surfaces are configured as any of the following: both the first and second vaporization surfaces are planar; one of the first and second vaporization surfaces is planar and the other is curved; or both the first and second vaporization surfaces are curved.

[0018] In one embodiment of a heater assembly for an aerosol delivery system, the tangential angles at both ends of the joint between the vaporization surface and the contact surface are acute angles. Compared to obtuse or right angles, acute angles can transfer aerosol-generating material more quickly, thereby further improving the oil transfer rate from the contact surface to the vaporization surface.

[0019] In one embodiment of a heater assembly for an aerosol delivery system, the tangential angles at both ends of the joint between the vaporization surface and the contact surface are the same.

[0020] In one embodiment of a heater assembly for an aerosol supply system, a heating wire forms a heating zone of a heating body, and the heating zone has a net-like structure having hollow holes.

[0021] A second aspect of an embodiment of the present invention discloses an aerosol supply system, wherein the system comprises an air flow channel and an atomization chamber for receiving a heater assembly as described in the first aspect, the air flow channel passing through the atomization chamber; and a heating body parallel to the direction of air flow of the air flow channel.

[0022] An aerosol delivery system having the aforementioned heater assembly improves the oil transfer rate of the heating wire, thereby reducing the possibility of dry burn failures on the vaporization surface of the heating wire. The orientation of the heating element parallel to the direction of air flow facilitates the transport of aerosol from the heating element by the air flow, increasing the contact area and time between the heating element and the air flow. This improves the delivery of more aerosol to the user, increasing the amount of puffable aerosol and improving the user experience.

[0023] In one embodiment of an aerosol delivery system, the system comprises a distal end and a mouthpiece end located at opposing ends in the height direction, and an air flow channel at the position of the heating component extends parallel to the height direction, and the extension direction of the heating body is parallel to the height direction. The vertical air flow channel allows for smoother air flow and is the shortest path for rapidly delivering the aerosol to the user, and prevents condensation of the aerosol into liquid due to prolonged movement in the air flow channel.

[0024] In one embodiment of the aerosol delivery system, the heating component is flat and parallel to the height direction.

[0025] In one embodiment of an aerosol delivery system, the system includes an aerosol outlet located at the end of a mouthpiece and an air inlet located at the distal end, and the air flow channel formed from the air inlet to the aerosol outlet is straight. The vertical air flow channel allows for smoother airflow, is the shortest path for rapidly delivering the aerosol to the user, and prevents the condensation of the aerosol into liquid due to prolonged travel in the air flow channel.

[0026] In one embodiment of an aerosol delivery system, it comprises: a housing having a holding chamber; and an aerosol generating material held within the holding chamber.

[0027] According to embodiments of the invention, by limiting the vaporization surfaces of the heating wire to a maximum of two, the aerosol-generating material on the contact surface of the heating wire needs to pass through at most two vaporization surfaces to complete delivery across the entire vaporization surface. Compared to existing technologies, the aerosol-generating material does not need to pass through multiple bending angles between multiple vaporization surfaces. This increases the oil transfer rate, reduces the possibility of dry burn failures on the vaporization surfaces of the heating wire, and thereby improves the user experience and the lifespan of the heater assembly.

In some alternative embodiments, the susceptor is on one or both sides of the material.

[0065] A consumable is an article comprising or constituting an aerosol-generating material, in whole or in part, intended to be consumed during use by a user.

The consumable may also include an aerosol generator, such as a heater, that emits heat to cause the aerosol-generating material to generate an aerosol upon use. The heater may include, for example, a combustible material, a material heatable by electrical conduction, or a susceptor.

[0066] A susceptor is a material capable of being heated by penetration by a varying magnetic field, such as an alternating magnetic field. The susceptor may be an electrically conductive material, and accordingly, penetration into this electrically conductive material by a varying magnetic field causes inductive heating of the heating material. The heating material may be a magnetic material, and accordingly, penetration into this heating material by a varying magnetic field causes magnetic hysteresis heating of the heating material. The susceptor may possess both electrical conductivity and magnetism, and accordingly, the susceptor may be heated by both heating mechanisms. A device configured to generate a varying magnetic field is referred to herein as a magnetic field generator.

[0067] An aerosol modifier is typically a substance located downstream of the aerosol generation region and is configured to modify the generated aerosol by, for example, changing the taste, flavor, acidity, or other properties of the aerosol. The aerosol modifier may be provided within an aerosol modifier release component operable to selectively release the aerosol modifier. The aerosol modifier may be, for example, an additive or an adsorbent. The aerosol modifier may include, for example, one or more of flavoring agents, coloring agents, water, and carbon absorbents. The aerosol modifier may be, for example, a solid, a liquid, or a gel. The aerosol modifier may be in the form of a powder, thread, or granules. The aerosol modifier may not contain filtration material.

[0068] An aerosol generator is a device configured to generate an aerosol from an aerosol generating material. In some embodiments, the aerosol generator is a heater configured to apply thermal energy to the aerosol generating material to release one or more volatile substances from the aerosol generating material to form an aerosol. In some embodiments, the aerosol generator is configured to generate an aerosol from the aerosol generating material without heating. For example, the aerosol generator may be configured to cause the aerosol generating material to undergo one or more of vibration, increased pressure, or electrostatic energy.

[0069] The present disclosure relates to aerosol delivery systems such as atomizers or e-cigarettes (which may also be referred to as vapor delivery systems). Throughout the following description, the terms "e-cigarette" or "electronic cigarette" may be used at times, but it will be recognized that these terms are interchangeable with aerosol delivery systems / devices and electronic aerosol delivery systems / devices. Furthermore, as is common in the art, the terms "aerosol" and "vapor," and related terms such as "vaporize," "volatilize," and "aerosolize" are generally interchangeable.

[0070] Aerosol delivery systems (e-cigarettes) often, but not always, comprise a modular assembly containing reusable device components and replaceable (disposable / consumable) cartridge components. Often, the replaceable cartridge component will include aerosol-generating material and a vaporizer (collectively referred to as a "cartomizer"), and the reusable device component will include a power supply (e.g., a rechargeable power source) and control circuitry. It will be recognized that these different components may include additional elements depending on their function. For example, the reusable device component will often include a user interface for receiving user input and displaying operating status characteristics, and the replaceable cartridge device component will include a temperature sensor to assist in controlling the temperature in some cases. The cartridges are electrically and mechanically coupled to a control unit for use, for example, using threaded, bayonet, 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.

[0071] Electronic cigarettes generally have an elongated shape. To provide a specific example, certain embodiments of the present disclosure will be considered to include this type of generally elongated two-part system utilizing disposable cartridges. However, it will be recognized that the basic principles described herein may be equally applied to other overall shapes based on different configurations, e.g., single-part systems or modular systems comprising two or more parts, refillable devices and single-use disposables, as well as e.g., so-called box-mod high-performance devices that typically have a more boxy shape. More generally, certain embodiments of the present disclosure will be recognized as being based on aerosol delivery systems operably configured to provide functions according to the principles described herein, and constitutive aspects of systems configured to provide functions according to the specific embodiments of the present disclosure will be recognized as not having significant importance.

[0072] As described in the background art, current heating wires are set with multiple vaporization surfaces, requiring liquid aerosol generating materials to pass through multiple vaporization surfaces and their connecting bending angles to complete delivery across the entire vaporization surface, which results in low oil guide rates. To address this, embodiments of the present invention innovatively propose setting the vaporization surfaces of the heating wire to a maximum of two. This allows the aerosol generating material on the contact surface of the heating wire to complete delivery across the entire vaporization surface by passing through a maximum of two vaporization surfaces, thereby improving the oil guide rate and reducing the occurrence of dry bundles on the vaporization surfaces of the heating wire.

[0073] The following will provide a detailed introduction to the heating assembly for an aerosol delivery system and the structure of the aerosol delivery system through specific embodiments.

[0074] Embodiment 1

[0075] A heater assembly is a component within an aerosol delivery system that generates an aerosol by heating an aerosol-generating material. Embodiment 1 of the present invention introduces a heating assembly used to heat a liquid aerosol-generating material (e.g., e-liquid).

[0076] FIG. 2 shows a perspective view of a heater assembly for an aerosol providing system provided by an embodiment of the present invention, and FIG. 3 shows a perspective view of a heating element of an aerosol providing system according to an embodiment of the present invention.

[0077] As illustrated in FIG. 2, the heater assembly (340) includes a heating element (341) and an oil guide body (342). The oil guide body (342) is configured to absorb a liquid aerosol generating material. In one embodiment of the invention, the oil guide body (342) may be cotton or ceramic, and in another embodiment, it may have a multilayer porous structure.

[0078] As an exemplary and non-limiting example, the oil guide rate of the oil guide body (342) near the side of the heating element (341) is lower than the oil guide rate of the side far from the heating element (341), and the oil absorption rate of the oil guide body (342) near the heating element (341) is higher than the oil absorption rate of the side far from the heating element (341). This arrangement increases the oil guide rate near the heating element (341) to improve its efficiency, while the part far from the heating element (341) has a higher absorption rate to increase the amount of oil in the heating element (341).

[0079] The heating element (341) includes a heating wire (3410) that forms its heating area to heat the aerosol generating material. The heating area is net-shaped with hollow holes, which may be circular or any polygonal shape. The heating element (341) may be flat or wound into a tubular shape.

[0080] In one embodiment of a heating assembly for an aerosol delivery system, the heating wire (3410) comprises a contact surface (34101) and a vaporization surface (34102) connected end-to-end sequentially along the circumferential direction of its cross section to form a closed loop. The contact surface (34101) contacts an oil guide body (342) to receive an aerosol generating material absorbed by the oil guide body (342) and transfers it to the vaporization surface (34102) for vaporization. In this embodiment of the invention, the heating wire (3410) comprises up to two vaporization surfaces (34102).

[0081] The heating element (341) comprises a plurality of heating wires (3410), and in this embodiment of the invention, at least some of the heating wires (3410) have the aforementioned arrangement.

[0082] Having up to two vaporization surfaces on the heating wire allows the aerosol-generating material on the contact surface of the heating wire to complete delivery across the entire vaporization surface by passing through up to two vaporization surfaces, thereby increasing the oil guide rate and reducing the occurrence of dry bundles on the vaporization surfaces of the heating wire.

[0083] FIGS. 4 to 7 are cross-sectional views of a heating wire for an aerosol delivery system provided by different embodiments of the present invention.

[0084] As illustrated in FIGS. 4 and 5, in some embodiments of the present invention, the heating wire (3410) comprises a vaporization surface (34102) forming a closed loop connected to both ends of a contact surface (34101). The vaporization surface (34102) is a curved surface without any bending angles. Specifically, the curve may be part of an S-shaped surface or a cylindrical surface. As illustrated in FIG. 4, the vaporization surface (34102) is an S-shaped curve with a smooth cross-section. As illustrated in FIG. 5, the vaporization surface (34102) is part of a cylindrical surface and forms a circular arc in cross-section. Other forms of curves without bending angles may also be implemented in other embodiments of the present invention, and are not specifically limited herein.

[0085] In embodiments of the present invention, by setting the vaporization surface of the heating wire as a curve without any bending angles, the aerosol generating material only needs to pass through a single vaporization surface without encountering any bending angles, thereby further increasing the oil guide rate and reducing the occurrence of dry bundles on the vaporization surface of the heating wire.

[0086] It should be noted that in the present invention, a bending angle refers to an intersection where two surfaces or lines meet at a bending angle having a non-smooth transition. Smooth curves do not have bending angles. In FIG. 6, the connection between two surfaces is a smooth transition and does not have a bending angle. In contrast, the connections at points A and B in FIG. 1, and point C in FIG. 7, have bending angles. The rate of the liquid aerosol generating material slows down when passing through these bending angles.

[0087] As illustrated in FIG. 6, unlike FIG. 4 and FIG. 5, this embodiment of the heating wire (3410) of the aerosol supply system has two vaporization surfaces (34102), namely a first and a second vaporization surface. The contact surface (34101), the first vaporization surface, and the second vaporization surface are connected end-to-end sequentially to form a closed loop. In FIG. 6, each vaporization surface (34102) has no bending angles, and the connection point D between the two vaporization surfaces (34102) transitions smoothly without any bending angles. Since there are no bending angles in each vaporization surface and in their connection, the liquid aerosol generating material can complete delivery across the entire vaporization surface without encountering any bending angles, thereby increasing the oil guide rate and reducing the occurrence of dry burn on the vaporization surface of the heating wire.

[0088] As illustrated in FIG. 7, unlike FIG. 4 through 6, this embodiment of the heating wire of the aerosol supply system has two vaporization surfaces (34102), namely a first and a second vaporization surface. The contact surface (34101), the first vaporization surface, and the second vaporization surface are connected end-to-end sequentially to form a closed loop. Each vaporization surface (34102) is not angled, but the connection point C between the two vaporization surfaces (34102) has a bending angle. Compared to the prior art, the reduction in the number of vaporization surfaces and bending angles can increase the oil guide rate at the vaporization surfaces, thereby reducing the occurrence of dry bundles at the vaporization surfaces of the heating wire.

[0089] If there are two vaporization surfaces, they may be configured as one of the following: both the first and second vaporization surfaces are flat; one of the first and second vaporization surfaces is flat and the other is curved; or both the first and second vaporization surfaces are curved. The present invention does not specifically limit these configurations.

[0090] In an embodiment of the present invention, the first and second vaporization surfaces have, in their cross-sections, a first side at their connection point and a second side connected to the contact surface. In both the first and second vaporization surfaces, the distances from the first side to the second side are equal. As shown in FIG. 7, the entire cross-section of the heating wire (3410) is an isosceles triangle, which means that the distances from both ends of the contact surface (34101) to the connection point C (the vertex of the triangle) are equal. Even if there are bending angles between the two vaporization surfaces, if the liquid aerosol generating material delivered from both ends of the contact surface can reach the bending angles simultaneously, the material does not need to pass through the bending angles to complete its delivery across the entire vaporization surface. By setting the distances from both ends of the contact surface to the connection point of the two vaporization surfaces to be equal, the possibility of the liquid aerosol generating material reaching the bending angles simultaneously is increased, thereby further improving the oil guide rate and reducing the occurrence of dry bundles on the vaporization surfaces of the heating wire.

[0091] In a further embodiment of the present invention, the cross-sections of the first and second vaporization surfaces form an axisymmetric shape, and the axis of symmetry passes through their connection point and is perpendicular to the contact surface. This ensures that the distance and path of the aerosol generating material transferred from both ends of the contact surface to the connection point of the two vaporization surfaces are exactly the same. The liquid aerosol generating material is more likely to reach the connection point of the two vaporization surfaces simultaneously, thereby further increasing the oil guide rate and reducing the occurrence of dry burn on the vaporization surface of the heating wire.

[0092] In one embodiment of the present invention, as shown in FIG. 6, the tangential angles θ at both ends of the vaporization surface (34102), where the vaporization surface (34102) is connected to the contact surface (34101), are acute angles such as 30°, 45°, etc. Compared to obtuse angles and right angles, acute angles can deliver the aerosol generating material more quickly, thereby increasing the oil guide rate from the contact surface to the vaporization surface and reducing the occurrence of dry bundles on the vaporization surface of the heating wire.

[0093] In a preferred embodiment, the tangential angles at both ends where the vaporization surface is connected to the contact surface are the same. This increases the probability that the liquid aerosol generating material reaches the connection point of the two vaporization surfaces simultaneously, thereby further increasing the oil guide rate at the vaporization surface and reducing the occurrence of dry bundles at the vaporization surface of the heating wire.

[0094] Embodiment 2

[0095] Corresponding to the heater assembly described in Embodiment 1, Embodiment 2 of the present invention provides an aerosol providing system comprising the heater assembly from Embodiment 1.

[0096] FIG. 8 illustrates a structural diagram of an aerosol delivery system provided in this embodiment of the present invention, while FIG. 9 and FIG. 10 are cross-sectional views of the system from different perspectives. Referring to FIG. 8 through FIG. 10, the aerosol delivery system is an elongated structure extending along the longitudinal axis. Along the height direction, the system comprises opposing proximal and distal ends and a housing (100) extending between them. The housing (100) at the proximal end has a mouthpiece end (101) that opens to an aerosol outlet (102). The housing (100) also features an air inlet (103) that can be positioned at the distal end, as shown in FIG. 9 and FIG. 10, or at other locations on the housing (100).

[0097] In one embodiment of the present invention, the system also includes a first sealing cap (104) for sealing an aerosol outlet (102) and a second sealing cap (105) for sealing an air inlet (103). When the aerosol supply system is not in use, the first and second sealing caps (104 and 105) may be applied for safety and hygiene.

[0098] Inside the housing (100) there is a holding space and an air flow channel. The holding space accommodates an aerosol generating material (e.g., e-liquid), an atomizer (300), a power source (battery component) (400), and a controller (control circuit) (500) within a holding chamber (200). The holding chamber (200), the atomizer (300), the controller (500), and the power source (400) are generally arranged along the height direction of the system. The power source (400) is configured to supply power to a heater assembly (340) within the atomizer (300) under the control of the controller (500). The atomizer (300) accommodates a heater assembly (340) within an atomization chamber (310). The atomization chamber (310) is fluidically connected to the holding chamber (200), allowing the aerosol generating material to enter the atomization chamber (310) through the liquid suction structure (600) and be heated by the heater assembly (340).

[0099] The air inlet (103), the atomization chamber (310), and the aerosol outlet (102) form an air flow channel within the housing. When a user inhales, external air enters through the air inlet (103), passes through the atomization chamber (310), carries the internal aerosol, and exits to the user through the aerosol outlet (102).

[0100] In one embodiment of the present invention, the system includes an aerosol outlet (102) located at the end of the mouthpiece (101) and an air inlet (103) at the distal end of the system. An air flow channel extends in a straight line from the air inlet (103) to the aerosol outlet (102). This configuration of the vertical air flow channel ensures smoother air flow and, as it is the shortest path, allows for rapid delivery of the aerosol to the user, thereby preventing the aerosol from condensing into liquid due to prolonged residence in the air flow channel.

[0101] Referring to FIGS. 8 through 10, the housing (100) comprises two separate parts: an upper housing (110) having a mouthpiece end (101), and a lower housing (120). The upper housing (110) accommodates a holding chamber (200) and an atomizer (300), while the lower housing (120) accommodates a power source (400) and a controller (500). The lower part of the upper housing (110) is fitted into the lower housing (120). In a replaceable embodiment, the upper housing (110) and the lower housing (120) do not substantially overlap along the height of the system, and the lower end of the upper housing (110) is connected to the upper end of the lower housing (120) to form a complete housing (100).

[0102] In one embodiment, the upper housing (110) and the lower housing (120) are designed to be detachably connected, allowing for the replacement of the aerosol generating material or the atomizer (300) within the upper housing (110) or for connecting the atomizer (300) to different power sources (400). In other embodiments, it should be understood that once assembled, the upper housing (110) and the lower housing (120) are permanently connected.

[0103] In an alternative embodiment different from the structure having independently set upper and lower housings as illustrated in FIGS. 8 to 10, the housing (100) may also be composed of a single integrated structure. Considering internal component assembly and reusability, the configuration of separate upper and lower housings offers more advantages compared to a single integrated housing.

[0104] In other embodiments of the present invention, the aerosol delivery system may be a box-shaped structure, and the atomizer (300) and power source (400) are arranged along a horizontally extending lateral direction. The housing (100) may be composed of a single box-shaped housing. Alternatively, the housing (100) may include two connectable housings, one housing accommodating the holding chamber (200) and the atomizer (300), and the other housing accommodating the power source (400) and the controller (500). These two housings may be designed for a detachable connection. Of course, in replaceable embodiments, once the two housings are assembled, they may be permanently connected.

[0105] The mouthpiece end (101) may be formed integrally with the housing (100) or detachably separated from it. The detachable mouthpiece end (101) facilitates cleaning and also helps access the interior of the housing (100) to replace the internal aerosol generating material.

[0106] The power source (400) is configured to supply power to the atomizer (300) and may typically be a battery assembly. In other examples, the battery may be replaced with a portable power source (capacitive energy storage devices such as supercapacitors or ultracapacitors), mechanical power sources (such as spring-powered or generator-based systems), or alternative chemical sources (such as fuel cells).

[0107] The aerosol generating material may be a solid, powder, or liquid. In one embodiment of the present invention, as illustrated in FIGS. 9 and 10, a holding chamber (200) is used to hold a liquid aerosol generating material. The holding chamber (200) includes an outer wall, which may be formed integrally with the housing (100), so that the outer wall forms part of the housing. Alternatively, the outer wall and the housing (100) may be two separate components, and the housing is set outside the outer wall. The outer wall covers at least part of the exterior of the atomizer (300), and the holding chamber (200) is formed by the outer wall and part of the surface of the atomizer (300).

[0108] To achieve aerosolization, the liquid aerosol generating material in the retention chamber (200) needs to be transferred to the atomization chamber (310). For this purpose, the system also includes a liquid suction structure (600) for transferring the liquid aerosol generating material from the retention chamber (200) to the atomization chamber (310).

[0109] In an embodiment provided by the present invention, FIG. 11 illustrates a schematic diagram of a liquid suction structure of an aerosol supply system. Referring to FIG. 9, FIG. 10, and FIG. 11, the liquid suction structure (600) comprises a support frame (610), a liquid suction channel (620), a first liquid suction hole (630), and a ventilation hole (640), wherein the liquid suction channel (620) is in fluid communication with both the retention chamber (200) and the atomization chamber (310).

[0110] The support frame (610) has interconnected liquid guide grooves (622) and annular grooves (621). As can be understood, the annular grooves (621) are located on the upper surface of the support frame (610) facing the retention chamber (200). The liquid guide grooves (622) may be composed of a number of sections, at least some of which extend longitudinally along the aerosol delivery system. The liquid guide grooves (622) and the annular grooves (621) together form the aforementioned liquid suction channel (620). The longitudinally extending liquid guide grooves (622) are arranged near the atomization chamber (310) in the transverse direction of the system. The liquid guide grooves (622) have a first side wall (6211) that forms part of one side of the atomization chamber (310). Both the first liquid intake hole (630) and the ventilation hole (640) are located on this first side wall (6211), penetrate it, and connect the liquid guide grooves (622) to the atomization chamber (310). Aerosol generating material from the retention chamber (200) enters the atomization chamber (310) through the liquid guide grooves (622) and the first liquid intake hole (630), and is absorbed by an oil guide body (342) positioned against the wall facing the first side wall (6211). The ventilation hole (640) is designed to communicate with the outside atmosphere. Accordingly, during use of the system, when the internal pressure within the retention chamber (200) decreases due to the consumption of the aerosol generating material, the external atmosphere enters the atomization chamber (310) due to the pressure difference, and then enters the liquid guide grooves (622) through the ventilation hole (640), subsequently entering the retention chamber (200) to maintain the liquid pressure balance.

[0111] In preferred embodiments of the present invention, the ventilation hole (640) is positioned above the first liquid suction hole (630) in the vertical direction of the system to ensure that bubbles generated from the aerosol generating material are not trapped in the first liquid suction hole (630), thereby preventing blockage and allowing smooth transfer of the aerosol generating material from the holding chamber (200) to the atomization chamber (310) without affecting the operation of the system.

[0112] FIG. 12 illustrates a schematic diagram of an atomizer structure in an aerosol supply system according to an embodiment of the present invention, and FIG. 13 is an exploded view of the same. Referring to FIG. 9, FIG. 12, and FIG. 13, the atomizer (300) comprises an atomization chamber (310), an atomizer bracket (320) forming the atomization chamber (310), an air channel component (330), and a heater assembly (340) located within the atomization chamber (310). The heater assembly (340) comprises a heating element (341) and an oil guide body (342). The atomizer bracket (320) comprises a structural component (321) and a support frame (610) that together form the atomization chamber. The support frame (610) has a receiving groove (611), into which the air channel component (330) is fitted. Both the heater assembly (340) and the air channel component (330) are clamped and fixed in the receiving groove (611) by the support frame (610) and the air channel component (330).

[0113] The atomizer (300) also includes a base assembly (350) that is detachably assembled on an atomizer bracket (320) and defines the lowest surface of the atomization chamber. The base assembly (350) has electrode holes for electrodes (352) to extend into the atomization chamber (310).

[0114] As illustrated in FIG. 6, the base assembly (350) includes a bottom cover (353) of the atomization chamber and a first air channel seal (354) positioned on the side of the bottom cover (353) facing the atomization chamber (310). Both the bottom cover (353) and the first air channel seal (354) have corresponding electrode holes for electrodes (352).

[0115] The system also includes a second air channel seal (700) for sealing between the support frame (610) and the retention chamber (200). In an implementation, the shape and size of the second air channel seal (700) are adapted to match the size and shape of the end of the support frame (610) closest to the retention chamber (200), but specific limitations are not provided herein. The outer wall of the retention chamber (200) is covered around the periphery of the second air channel seal (700), and the portion of the outer wall in contact with the second air channel seal (700) is assembled with an interference fit. This prevents the aerosol generating material within the retention chamber (200) from leaking and contaminating other components within the aerosol supply system, such as battery components. At the same time, to achieve fluid communication between the holding chamber (200) and the liquid guide grooves (622), the second air channel seal (700) is provided with a second liquid suction hole (710), allowing the aerosol generating material in the holding chamber (200) to enter the liquid guide grooves (622) through this second liquid suction hole (710).

[0116] FIG. 14 is a schematic diagram of an air flow channel inside an atomization chamber of an aerosol supply system provided by an embodiment of the present invention, and FIG. 15 is a cross-sectional view from the perspective of FIG. 14. As shown in FIG. 14 and FIG. 15, an air channel component (330) has an air channel groove and forms an air flow channel (360) over the atomization chamber (310) between it and a heating element (341). An oil guide body (342) is positioned on the side of the heating element (341) away from the air flow channel (360).

[0117] In one embodiment of the present invention, the heating element (341) is parallel to the direction of air flow of the air flow channel (360). This parallel arrangement increases the contact area and time between the heating element and the air flow, thereby facilitating the delivery of more aerosol from the heating element to the user, which consequently increases the amount of aerosol that can be inhaled and improves the user experience.

[0118] In one embodiment of the present invention, the extension direction of the air flow channel (360) at the location of the heater assembly (340) is parallel to the vertical direction of the system, and the extension direction of the heating element (341) is also parallel to the vertical direction of the system.

[0119] More preferably, the heater assembly (340) is flat and parallel to the vertical direction of the system.

[0120] The arrangement of the extension direction of the air flow channels parallel to the vertical direction of the system forms vertical air flow channels within the atomization chamber, making airflow smoother. Since these vertical air flow channels are the shortest path, they deliver the aerosol quickly to the user, preventing the aerosol from condensing into liquid if it remains in the air flow channels for too long.

[0121] In a further embodiment of the present invention, a plurality of grooves are set on the surface of an air channel component (330) to collect condensate formed from aerosol condensation in an atomization chamber (310), thereby preventing the condensate from leaking out of the atomization chamber.
