The material may be present on or in a support, to form a substrate. The support may, for example, be or comprise paper, card, paperboard, cardboard, reconstituted material, a plastics material, a ceramic material, a composite material, glass, a metal, or a metal alloy. In some embodiments, the support comprises a susceptor. In some embodiments, the susceptor is embedded within the material. In some alternative embodiments, the susceptor is on one or either side of the material.

A consumable is an article comprising or consisting of aerosol-generating material, part or all of which is intended to be consumed during use by a user. A consumable may comprise one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material transfer component, an aerosol generation area, a housing, a wrapper, a mouthpiece, a filter and/or an aerosol-modifying agent. A consumable may also comprise an aerosol generator, such as a heater, that emits heat to cause the aerosol-generating material to generate aerosol in use. The heater may, for example, comprise combustible material, a material heatable by electrical conduction, or a susceptor.

A susceptor is a material that is heatable by penetration with a varying magnetic field, such as an alternating magnetic field. The susceptor may be an electrically-conductive material, so that penetration thereof with a varying magnetic field causes induction heating of the heating material. The heating material may be magnetic material, so that penetration thereof with a varying magnetic field causes magnetic hysteresis heating of the heating material. The susceptor may be both electrically-conductive and magnetic, so that the susceptor is heatable by both heating mechanisms. The device that is configured to generate the varying magnetic field is referred to as a magnetic field generator, herein.

An aerosol-modifying agent is a substance, typically located downstream of the aerosol generation area, that is configured to modify the aerosol generated, for example by changing the taste, flavour, acidity or another characteristic of the aerosol. The aerosolmodifying agent may be provided in an aerosol-modifying agent release component, that is operable to selectively release the aerosol-modifying agent. 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.

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 aerosolgenerating 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.

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.

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. Systems and devices conforming to this type modular configuration may generally be referred to as a multi-part modular configuration or multi-part systems/devices. 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.

The existing structure of aerosol provision systems cannot directly separate the battery from the e-cigarette device for recycling, or it requires a significant amount of time and manpower to detach the battery from the system. Consequently, the recycling process after the use of aerosol provision systems becomes a time-consuming and labor-intensive task. In light of this, this application discloses a new structure for an aerosol provision system that allows the battery bracket used to secure the battery component to be quickly and conveniently disassembled from the outer casing, facilitating subsequent recycling of the battery component.

It is noted that the aerosol provision system in this embodiment can be either a boxtype aerosol provision system or a pen-type aerosol provision system. This application does not specifically limit it. The following description will focus on a pen-type aerosol provision system as an example to emphasize the detachable structure of the aerosol provision system.

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

As used herein the terms ‘proximal’ and ‘near’, and ‘distal’ and ‘away from’ as applied to features will be described by reference to the relative positioning of such features with respect to each other.

Embodiment One

Figure 1 is a schematic diagram of the three-dimensional structure of the aerosol provision system described in embodiments of this application. Figure 2 is a schematic sectional view of the aerosol provision system described in embodiments this application. Figure 3 is a schematic exploded view of a partial structure of the aerosol provision system described in embodiments of this application. As shown in Figure 1-3, taking a pen-style aerosol provision system as an example, it generally comprises a shell 100, battery holder 200, bottom cap 300, mouthpiece component 400, liquid storage compartment 500, atomization core 600, and battery component 700. Inside the shell 100, a containing space and an airway (not shown in the figure) are formed, with part of the containing space constituting the battery containing chamber (not shown in the figure). The battery component 700 is placed in the battery-containing cavity, while components such as the liquid storage compartment 500 and atomization core 600 are set or at least partially set in the remaining space of the containing space, excluding the battery-containing cavity. The battery holder 200 is primarily used to secure the battery component 700, and it is placed in the battery-containing cavity along with the battery component 700. The bottom cap 300 is securely connected to the battery holder 200, and both the bottom cap 300 and the battery holder 200 can be detachably connected to the shell 100. This allows the bottom cap 300 and the battery holder 200 to be quickly and conveniently detached from the shell 100, facilitating the subsequent recycling of the battery component 700.

The battery-containing cavity may be a battery containing chamber. In embodiments, the bottom cap 300 is fixedly connected to the battery holder 200. A battery module may be or comprise the battery component.

It is noted that the specific structure and material of the battery holder 200 are not restricted in this embodiment. It only needs to fulfill the function of securing the battery component, and in practical implementation, the design of the battery holder can be adjusted based on the actual product requirements. As an illustrative example and not a limitation, the battery holder in any embodiments can be a cylindrical structure, forming a space inside to accommodate the battery cell. Alternatively, it can be a frame structure where the battery cell is secured within the frame. The battery holder can also be a component located at the bottom of the battery cell, with the battery cell connected to the bottom cap through this component. Further referring to Figure 3 as an illustrative example and not a limitation, the battery holder 200 in this embodiment is in a cylindrical structure.

In embodiments of this application, the battery component 700 can be either permanently connected to or detachably connected to the battery holder 200. This means that when detaching the battery holder 200 and the bottom cap 300 from the shell 100, the battery component 700 can be removed either together with the battery holder 200 or separately after removing the battery holder 200 and the bottom cap 300. The specific configuration is not strictly defined here, and the choice can be made based on the actual product requirements during practical application. In embodiments, the bottom cap 300 and the battery holder 200 can be connected to the shell 100 through the connecting component 800.

The connecting component 800 in embodiments is a connecting assembly. The connecting assembly may comprise a first connecting element 810a and a second connecting element 820a. The connecting element or each connecting element may be a connecting piece.

The first connecting element 810a and the second connecting element 820a are used in conjunction as complementary components. The first connecting element 810a is located on the shell 100, while the second connecting element 820a is located on the bottom cap 300 or the battery holder 200. The first connecting element 810a and the second connecting element 820a can be detachably connected, thereby achieving a detachable connection between the bottom cap 300, the battery holder 200, and the shell 100.

In embodiments, the first connecting element 810a and the second connecting element 820a are used in conjunction as complementary components.

In embodiments, the first connecting element 810a and the second connecting element 820a may be snap-connected. One of the first connecting element 810a and the second connecting element 820a can serve as a connecting buckle, while the other serves as a connecting hole that complements the connecting buckle. For example, the first connecting element 810a can be the connecting buckle, and the second connecting element 820a can be the connecting hole, or vice versa. It can be understood that to achieve the snap connection between the first connecting element 810a and the second connecting element 820a, the connecting buckle can be an elastic element. Alternatively, the part (i.e. , connecting hole part) of the shell, bottom cap, or battery holder connected to the connecting buckle can be an elastic element. Another option is that both the connecting buckle and the connecting hole are elastic elements, enabling a detachable connection between the connecting buckle and the connecting hole.

Further referring to Figure 3, in embodiments, the first connecting element 810a serves as the connecting hole, while the second connecting element 820a serves as the connecting buckle. The connecting hole is positioned on the shell 100 near one end of the bottom cap 300, and it is arranged circumferentially along the periphery of the shell 100. The connecting hole extends laterally on the shell 100. The connecting buckle is located on the bottom cap 300 and is arranged circumferentially along the periphery of the bottom cap 300. The connecting buckle may be a protrusion extending along the circumferential surface of the bottom cap 300 in the direction away from the bottom cap.

In embodiments, the connecting buckle may serve as an elastic element. When the bottom cap 300 is in a connected state with the shell 100, the connecting buckle is engaged in the connecting hole. When it is necessary to disassemble the battery component 700 from the shell, one can simply press the connecting buckle. Due to the deformation caused by the pressure, the connecting buckle disengages from the connecting hole. As a result, the bottom cap 300 can be quickly and conveniently detached from the shell 100, allowing for the rapid and easy disassembly of the battery component.

In embodiments, the number of first connecting elements 810a and second connecting elements 820a may be equal and can both comprise multiple units. Multiple first connecting elements 810a may be arranged at intervals along the circumference of the shell 100, and multiple second connecting elements 820a may be arranged at intervals along the circumference of the bottom cap 300. Each position of a first connecting element 810a on the shell 100 corresponds to the position of one of the second connecting elements 820a on the bottom cap 300, the details are not explicitly described here.

The terms ‘multiple’ and ‘plurality’ may be used interchangeably.

In embodiments, there is no specific limitation on the shape and quantity of the connecting elements and connecting holes. As long as they are mutually compatible and do not deviate from the conceptual basis of the application, any known shapes are acceptable for the connecting elements or connecting holes in this embodiment. For example, the connecting elements or connecting holes may have shapes such as circular, square, rectangular, rhombic, trapezoidal, triangular, and any type of polygon, including but not limited to equilateral or non-equilateral pentagon, hexagon, octagon, and so on, without exhaustive listing. The quantity of connecting elements and connecting holes can be set according to the actual requirements of the product. As an illustrative rather than restrictive example, in this embodiment, there are 2 connecting elements and connecting holes, with each pair located on the shell 100 and the bottom cap 300 in a corresponding manner.

The first connecting element 810b may comprise a limiting groove opened at one end of the structural member 110 near the bottom cap 300, and the second connecting element 820b comprises a guide block set on the bottom cap 300 or the battery holder 200. The guide block can move along the limiting groove, and in the connected state of the shell 100 and the bottom cap 300, the guide block is engaged in the limiting groove. As an example, the second connecting element 820b is a guide block set on the bottom cap 300. The limiting groove may be known as a position limit groove. The guide block may be clamped in the position limit groove. The guide block may be arranged on the bottom cap 300 or the battery holder 200. As an example, the second connecting element 820b is may be a guide block set arranged on the bottom cap 300. The position limit groove may be a spiral groove or an arc-shaped groove. The position limit groove may be a helical groove.

To prevent the guide block from disengaging from the limit groove, in embodiments, the guide block can be designed as an elastic element and positioned in the width direction of the limiting groove. The width of the guide block is greater than the slot width of the limiting groove, allowing the guide block to be accommodated in the limiting groove and preventing it from disengaging.

In embodiment, a friction element (not shown) can be introduced between the limiting groove and the guide block to increase the friction force between them and prevent the guide block from disengaging. The friction element can be a silicone component positioned between the limiting groove and the guide block, or it can be a rough surface set on the side wall of the limiting groove. There is no specific limitation as long as it achieves the goal of increasing the friction force between the limiting groove and the guide block.

The friction element in embodiments is a friction piece.

Referring to Figure 9, the inner wall of the structural member 110 near the end close to the bottom cap 300 has a passage groove 120. One end of the passage groove 120 is connected to the exterior of the structural member 110, and the other end is connected to the limiting groove. The guide block can enter the limit groove through the passage groove 120. In the state where the shell 100 is connected to the bottom cap 300, the guide block engages with the limiting groove at the end away from the passage groove, preventing the guide block from disengaging from the limit groove. It can be understood that the passage groove 120 may be a blind hole or through hole, and there is no specific limitation on this.

In embodiments, one end of the passage groove 120 extends to the exterior of the structural member 110, and the other end extends to the limiting groove.

Further referring to Figures 7 and 8, in embodiments, the connecting component 800 also comprise at least one position limit piece 830b.
