Description

[0001] AEROSOL PROVISION SYSTEM

[0002] Technical Field

[0003] The present invention relates to the field of aerosol provision, particularly relating to an aerosol provision system.

[0004] Background

[0005] Electronic cigarette-type aerosol provision systems, which heat but do not combust aerosol-generating materials containing aerosol-forming substrates (such as tobacco), generally utilize heaters or similar devices to heat the aerosol-generating materials to a sufficiently high temperature for the generation of aerosol for puffing by the user. Aerosol delivery systems typically use batteries to provide power to the heater. However, it is well- known that indiscriminate disposal of used batteries not only causes serious environmental pollution but also poses a significant risk to human health. Therefore, it is necessary to recycle and process the batteries from used aerosol delivery systems.

[0006] Summary

[0007] In accordance with some embodiments described herein, there is provided an aerosol provision system, at least comprising a shell and a mouthpiece, the shell comprises a first housing and a second housing that are arranged along the length direction of the system, the first housing is arranged near the mouthpiece with respect to the second housing, the second housing is formed with a battery containing chamber inside, and the first housing is detachably connected to the second housing.

[0008] By setting the shell as the first housing and the shell with a battery compartment as the second housing, and arranging the first housing and the second housing to be detachably connected, the second housing used to accommodate the battery component may be quickly and conveniently detached from the first housing, and may facilitate the subsequent recycling of the battery component.

[0009] The system may further comprise a battery module arranged in the battery containing chamber, and the battery module may be fixedly connected to the second housing, or the battery module may be detachably connected to the second housing.

[0010] The system may further comprise a connecting assembly, the first housing may have a first holder inside, the second housing may have a second holder inside, the connecting assembly may comprise a first connecting piece arranged on the first housing or the first holder, and a second connecting piece arranged on the second housing or the second holder, and the first connecting piece may be detachably connected to the second connecting piece.

[0011] One of the first connecting piece and the second connecting piece may be a connecting buckle, and the other one thereof may be a connecting hole that matches the connecting buckle.

[0012] The first holder may comprise a base of an atomizing core arranged within the first housing, and the first connecting piece may be arranged on the base of the atomizing core.

[0013] There may be multiple connecting assemblies spaced along the circumferential direction of the system.

[0014] One of the first connecting piece and the second connecting piece may be a guide block, and the other one thereof may be a position limit groove that matches the guide block, the guide block may be movable along the position limit groove, and in a state where the first housing is connected to the second housing, the guide block may be clamped in the position limit groove.

[0015] The first connecting piece may be a guide block, the second connecting piece may be a position limit groove, the guide block may be arranged on the first holder, and the position limit groove may be arranged on the second housing.

[0016] The first holder may comprise an atomizing core, and the guide block may be integrally formed with a base of the atomizing core or the guide block may be connected to the base of the atomizing core.

[0017] The guide block may be an elastic element, and in the width direction of the position limit groove, the width of the guide block may be greater than the groove width of the position limit groove.

[0018] Setting the width of the guide block in the width direction of the position limit groove to be greater than the groove width of the position limit groove may ensure that the guide block is securely positioned within the position limit groove, preventing it from dislodging.

[0019] A friction piece may be provided between the position limit groove and the guide block.

[0020] By introducing a friction piece between the position limit groove and the guide block, the friction force between the position limit groove and the guide block may be increased, preventing the guide block from dislodging from the position limit groove.

[0021] One end of the position limit groove near the first housing may have an opening, the guide block can enter the position limit groove through the opening, and in the state where the first housing is connected to the second housing, the guide block may be clamped at one end of the position limit groove away from the opening.

[0022] The connecting assembly may further comprise at least one position limit piece, and the position limit piece may be arranged at one end of the position limit groove away from the opening and is located on either side wall of the position limit groove.

[0023] By placing position limit pieces within the position limit groove, the guide block can be constrained within the groove by these limit pieces, preventing the guide block from dislodging from the position limit groove.

[0024] The guide block or the position limit piece may be an elastic element, and the distance between the position limit piece and the side wall of the position limit groove which it faces may be less than the size of the guide block in the width direction of the position limit groove.

[0025] By configuring the guide block or position limit piece as an elastic element and ensuring that the distance between the position limit piece and the side wall of the position limit groove it faces is less than the size of the guide block in the width direction of the position limit groove, on the one hand, it may facilitate the passage of the guide block through the gap between the position limit piece and the position limit groove, and on the other hand, it may allow the position limit piece to constrain the guide block within the position limit groove, preventing the guide block from dislodging from the groove.

[0026] The position limit groove may comprise at least a first portion and a second portion that are in communication with each other, and the first portion and the second portion may be arranged at an angle to each other.

[0027] The position limit groove may further comprise a third portion, the third portion may be arranged at one end of the second portion away from the first portion and may be in communication with the second portion, the third portion may be arranged at an angle to the second portion, and in the state where the first housing is connected to the second housing, the guide block may be clamped in the third portion.

[0028] By configuring the third portion at an angle relative to the second portion, in the state where the first housing is connected to the second housing, the guide block may be clamped in the third portion, preventing the guide block from dislodging from the position limit groove.

[0029] The guide block may be an elastic element, and the width at the connection between the third portion and the second portion may be less than the size of the guide block in the width direction of the second portion. By setting the guide block as an elastic element and limiting the width at the connection between the third portion and the second portion to be smaller than the size of the guide block in the width direction of the second portion, on the one hand, it may facilitate the passage of the guide block through the gap between the position limit piece and the position limit groove, and on the other hand, it may further prevent the guide block from dislodging from the position limit groove.

[0030] The position limit groove may be a spiral groove or an arc-shaped groove, and the spiral groove or the arc-shaped groove may be arranged on the second housing along the circumferential direction of the second housing.

[0031] The outer diameter of one end of the first housing near the second housing may be less than the outer diameter of one end of the second housing near the first housing, and the second housing may be partially sleeved on the first housing; or, the outer diameter of one end of the first housing near the second housing may be greater than that of one end of the second housing near the first housing, and the first housing may be partially sleeved on the second housing.

[0032] The first housing may be connected to the second housing through a binder.

[0033] The system may further comprise a packaging material wrapped outside the first housing and the second housing, and the packaging material may be provided with multiple through holes arranged along the circumferential direction of the system at the connection between the first housing and the second housing.

[0034] The first housing may be provided inside with an air passage and an atomizing chamber in communication with the air passage, the atomizing chamber may be provided with an atomizing core inside, the atomizing core may comprise a heater, and an atomizing surface of the heater may be parallel to the length direction of the system.

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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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 “cartom izer”) 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.

[0084] 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.

[0085] As mentioned in the technical background, the existing structures of aerosol provision systems do not allow the battery to be easily separated and recovered from the e-cigarette, or it requires a significant amount of time and labour to detach the battery from the system. This makes the recycling process, after using an aerosol provision system, a time-consuming and labour-intensive task. In view of this, this application proposes a new structure for an aerosol provision system where the second housing, used to accommodate the battery component, can be quickly and easily detached from the first housing. This helps facilitate the subsequent recycling process of the battery component.

[0086] 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.

[0087] 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.

[0088] Embodiment one Figure 1 is a three-dimensional schematic diagram of an aerosol provision system provided in an embodiment of this application, and Figure 2 is a three-dimensional schematic diagram of the aerosol provision system after removing a packaging in an embodiment of this application. Figure 3 is a sectional schematic diagram of the aerosol provision system in an embodiment of this application. Figure 4 is the structure of the first housing and the base of the atomizing core in the aerosol provision system provided in an embodiment of this application. Referring to Figures 1 to 4, the aerosol provision system in an embodiment generally comprises components such as the shell 100, mouthpiece 200, liquid storage structure 300, atomizing core 400, and battery component 500. Internally, the shell 100 forms a storage space and an airway (not shown in the figure), with the battery component 500 set in the battery accommodation cavity. The liquid storage structure 300, atomizing core 400, and other components are set, at least partially, in the remaining space inside the storage space, excluding the battery accommodation cavity. Unlike other aerosol provision systems in the prior art, in this embodiment, the shell 100 is composed of two parts: the first housing 110 and the second housing 120. The first housing 110 and the second housing 120 are arranged along the length direction of the system, with the first housing 110 positioned closer to the mouthpiece 200. The second housing 120 forms an internal battery accommodation cavity (not shown in the figure), and part of the storage space constitutes the battery accommodation cavity, which is used to place the battery component. The first housing 110 and the second housing 120 are detachably connected, and the second housing that accommodates the battery can be quickly and conveniently detached from the first housing, facilitating subsequent recycling of the battery component.

[0089] It is worth noting that, in such an embodiment, the specific shape and material of the shell (comprising the first housing and the second housing) are not limited. As an illustrative example rather than a restrictive one, the shell in this embodiment can have a cylindrical structure, and it can be made of metal or non-metal materials. The selection of the specific shape and material of the shell can be based on the actual product requirements during implementation.

[0090] In embodiments, it is understood that the battery component 500 and the second housing 120 can be permanently connected or detachably connected. That is, when detaching the second housing 120 from the first housing 110, the battery component 500 can be removed together with the second housing 120 or separately after detaching the second housing 120. The specific connection method is not limited here and can be chosen based on the product requirements in practical applications. In embodiments, the connection between the first housing 110 and the second housing 120 can be achieved through a connecting component 600. In a specific implementation, the connecting component includes mutually coordinated first connector 610a and second connector 620a. The first connector 610a and the second connector 620a are detachably connected, thereby enabling a detachable connection between the first housing 110 and the second housing 120.

[0091] In embodiments, the first housing 110 has a first holder 111 , and the second housing 120 has a second holder. The first holder 111 and the second holder can be any structural component inside the first housing 110 or the second housing 120, and this embodiment does not specifically limit this.

[0092] In embodiments, the first connector 610a is located on the first housing 110, and the second connector 620a is located on the second housing 120.

[0093] In embodiments, the first connector 610a is located on the first holder 111 , and the second connector 620a is located on the second holder.

[0094] In embodiments, the first connector 610a is located on the first housing 110, and the second connector 620a is located on the second holder.

[0095] In embodiments embodiment, the first connector 610a is located on the first holder 111 , and the second connector 620a is located on the second housing 120.

[0096] In embodiments, a snap-fit connection is established between the first connector 610a and the second connector 620a. Specifically, one of the first connector 610a and the second connector 620a can be a connecting buckle, and the other can be a connecting hole that matches the connecting buckle. In other words, the first connector 610a can be the connecting buckle, and the second connector 620a can be the connecting hole, or vice versa. It is understood that to achieve the snap-fit connection between the first connector 610a and the second connector 620a, the connecting buckle can be an elastic element. The shell, bottom cover, or battery holder may also serve as an elastic element that connects with the connecting buckle, or both the connecting buckle and the connecting hole can be elastic elements, enabling a detachable connection between them.

[0097] Further referring to Figure 4, in embodiments, the first holder 111 comprises a base of the atomizing core positioned inside the first housing 110, and the first connector 610a is set on the base of the atomizing core. In this embodiment, the first connector 610a serves as the connecting hole, while the second connector 620a serves as the connecting buckle. The connecting hole is located at one end of the first housing 110 near the second housing 120, and it is arranged circumferentially along the first housing 110, extending laterally along the outer shell of the first housing 110. The connecting buckle is positioned on the base of the atomizing core and is arranged circumferentially along the base of the atomizing core. In a specific implementation, the connecting buckle protrudes in the circumferential direction along the surface of the base of the atomizing core, extending towards the direction away from the base of the atomizing core.

[0098] In embodiments, the connecting buckle is designed as an elastic element. When the first housing 110 and the second housing 120 are in a connected state, the connecting buckle securely fits into the connecting hole. When it is necessary to detach the second housing, used to accommodate the battery component, from the first housing, one can directly press the connecting buckle. Due to the pressure, the connecting buckle undergoes deformation and disengages from the connecting hole, allowing the second housing to detach quickly and conveniently from the first housing. This enables the rapid and easy removal of the battery component.

[0099] In embodiments, the thickness of the connecting buckle is designed to be smaller than the depth of the connecting hole. With this configuration, when it is necessary to detach the second housing, which is used to accommodate the battery component, from the first housing, one can grip the first housing and the second housing separately and pull them in opposite directions. This action causes the connecting buckle to disengage from the connecting hole, allowing the second housing to detach quickly and conveniently from the first housing. This facilitates the rapid and easy removal of the battery component.

[0100] In embodiments , the number of the first connector 610a and the second connector 620a is equal and can comprise multiple units. Multiple first connectors 610a are arranged along the circumferential direction of the first housing 110 at intervals, and multiple second connectors 620a are arranged along the circumferential direction of the second housing 120 at intervals. Each position of a first connector 610a on the first housing 110 corresponds to the position of one of the second connectors 620a on the second housing 120. Herein, detailed repetition is omitted.

[0101] It is noted that, in embodiments, there are no specific restrictions on the specific shape and quantity of the connecting buckle and connecting hole. As long as they are compatible, any known shape can be used as the shape of the connecting buckle or connecting hole. For example, the connecting buckle or connecting hole can have any shape among circular, square, rectangular, rhombic, trapezoidal, triangular, and various polygons. Polygons comprise but are not limited to equilateral or non-equilateral pentagons, hexagons, octagons, and so on. Herein, specific shapes are not exhaustively listed. Figure 5 is the structural schematic diagram of the liquid storage structure described in an embodiment of this application. Referring to Figure 5, in embodiments, the liquid storage structure 300 is arranged in the first housing 110. The liquid storage structure 300 comprises an oil-absorbing body 310 and a hollow tube 320. The oil-absorbing body 310 is sleeved on the outside of the hollow tube 320, and the internal space of the hollow tube 320 forms the system's air passage. One end of the hollow tube 320 is in communication with the mouthpiece 200, and the other end is connected to the atomization chamber of the atomizing core. It is noted that in this embodiment, there are no specific limitations on the materials of the oilabsorbing body and the hollow tube. The specific implementation can be chosen based on the actual product requirements. As an illustrative rather than restrictive example, the oilabsorbing body 310 in this embodiment can be a cotton core, and the hollow tube can be made of copper, for example.

[0102] It can be understood that the aerosol provision system in embodiments also comprises an air inlet 700. The air inlet 700 establishes communication between the air passage (not shown in the figure) and the external atmosphere of the aerosol provision system. The atomization chamber is in fluid communication to the air passage, the air inlet 700, and the outlet of the mouthpiece 200. This facilitates the puffing of aerosol by the user from the outlet of the mouthpiece 200.

[0103] Figure 6 is the exploded view of the atomizing core described in embodiments. Referring to Figure 6, the atomizing core 400 comprises a heater, an atomization chamber for accommodating the heater, a fixing holder 420 for securing the heater, and the base 430 of the atomizing core. The heater is positioned on the fixing holder 420, and the fixing holder 420 is set on the base 430 of the atomizing core. The heater includes a heating body 441 and an oil-guiding body 442. The oil-guiding body 442 is set outside the heating body 441 and is in contact with at least a portion of the oil-absorbing body 310 of the liquid storage structure 300. As an illustrative and non-limiting example, the heating body 441 has a hollow tubular structure with a mesh-like surface, and the mesh pores are circular or of any polygonal shape. The heating body 441 has an atomization surface parallel to the length direction of the system. The oil-guiding body 442 has a lower oil-guiding rate on the side near the heating body 441 than on the side away from the heating body 441. The oil-absorbing rate on the side near the heating body 441 is higher than on the side away from the heating body 441. This design enhances the oil-guiding efficiency in the part of the oil-guiding body 442 near the heating body 441 and increases the oil-absorbing amount at the heating body 441 .

[0104] In embodiments, the aerosol system in this application further comprises packaging material 800. The packaging material 800 wraps around the exterior of the first housing 110 and the second housing 120. The packaging material 800 has multiple through-holes 810 arranged along the circumference of the system at the connection point corresponding to the first housing 110 and the second housing 120. The through-holes 810 constitute the air inlet 700 of the system. When it is necessary to detach the second housing 120 from the first housing 110, one can grip the first and second housings and pull them in opposite directions. The packaging material breaks at the through-holes, causing the connecting clasps to detach from the connecting holes. As a result, the second housing detaches from the first housing, allowing the battery component to be quickly and conveniently disassembled.

[0105] In embodiments, there is no specific limitation on the composition of the battery component 500. Any known battery component can be used in this application. Referring to Figure 7, the battery component 500 may comprise components such as the battery core 510, the top cover 520 set above the battery core, and the control circuit board 530 connected to the battery core. In embodiments, the top cover 520 is also equipped with an air-cutting hole 521 and a storage groove 522, where the groove of the storage groove 522 faces the second housing 120. The air-cutting hole 521 is positioned in the bottom wall of the storage groove 522, and the fluid flux at the air-cutting hole 521 is minimized in the airway. The air-cutting hole 521 is in communication with the air inlet 700, and the bottom surface of the base 430 of the atomizing core forms a cavity with ventilation holes (not shown in the figure). The atomizing chamber is in fluid communication with the cavity through ventilation holes, air-cutting holes, the cavity, and ventilation holes are sequentially in fluid communication.

[0106] In embodiments, there is also no specific limitation on the composition and material of the mouthpiece 200. Any known mouthpiece can be used in this application. For example, the mouthpiece 200 can be made of silicone material or composed of a cotton core with a waterproof layer covering the outside of the cotton core. Various other configurations are possible, and the examples provided are not exhaustive

[0107] Embodiment Two

[0108] A difference from Embodiment one is that the structure of the connecting component in this embodiment differs from the structure of the connecting component in Embodiment one. The structures of the other components may be the same or different from Embodiment one, and relevant details can be referred to in the corresponding part of Embodiment one, which is not reiterated here.

[0109] Referring to Figure 8, in embodiments, the connecting component comprises mutually cooperating first connector 610b and second connector 620b. The connection between the first connector 610b and the second connector 620b remains a snap-fit connection, thereby achieving a detachable connection between the first housing and the second housing. In implementations, one of the first connector 610b and the second connector 620b can serve as the connecting buckle, and the other as the connecting hole that complements the buckle. For example, the first connector 61 Ob can be the connecting buckle, and the second connector 620b can be the connecting hole, or vice versa. It is understood that, to achieve the snap-fit connection between the first connector 610b and the second connector 620b, the connecting buckle can be an elastic element. The elastic element can be part of the shell, bottom cover, or battery bracket connected to the connecting buckle (i.e., the connecting hole portion), or both the connecting buckle and the connecting hole can be elastic elements, enabling a detachable connection between the connecting buckle and the connecting hole.

[0110] In embodiments, the first housing contains the first holder 111 b, and the second housing contains the second holder 121 b. The first connector 610b is a connection hole set on the first holder 111 b, and the second connector 620b is a connecting buckle set on the second holder 121 b. Referring further to Figure 8, the first holder 111 b comprises a bottom base for the atomizing core set inside the first housing, and the second holder 121b comprises a battery holder set inside the second housing to secure the battery component within the second housing. The bottom base of the atomizing core has a first surface facing the battery holder, and the battery holder has a second surface facing the bottom base of the atomizing core. The first connector 610b (i.e., connection hole) is set on the first surface, and the second connector 620b (i.e., connecting buckle) is set on the second surface. In the lateral direction of the aerosol supply system, at least a portion of the connecting buckles have dimensions larger than those of the connection holes, ensuring that the connecting buckles are securely fitted into the connection holes and not easily detached.

[0111] Further referring to Figure 8, the connecting buckle comprises a body 621b connected to the second surface and a flange 622b extending outwardly along the lateral direction of the aerosol provision system at one end of the body 621 b away from the second surface. In the lateral direction of the aerosol provision system, the size of the flange 622b is larger than that of the connection hole. The connection hole is an opening set on the first surface and extends axially through the bottom base of the atomizing core.

[0112] It can be understood that the connecting buckle is integrally formed with the battery bracket 121 b or connected to the battery bracket 121b. At least a portion of the battery bracket 121 b, away from one end of the first housing, is exposed to the outside of the second housing. In this way, when it is necessary to detach the second housing from the first housing, one can grip the first housing and the second housing separately and pull them in opposite directions. This causes the connecting buckle to disengage from the connecting hole, allowing the second housing to detach from the first housing. This enables the rapid and convenient disassembly of the battery component.

[0113] Embodiment Three

[0114] A difference from Embodiment one is that the structure of the connecting component in this embodiment differs from the structure of the connecting component in Embodiment one. The structures of the other components may be the same or different from Embodiment one, and relevant details can be referred to in the corresponding part of Embodiment one, which is not reiterated here.

[0115] Referring to Figure 9, in embodiments, the connecting component 600 comprises the first connecting component 610c and the second connecting component 620c. One of the first connector 610c and the second connector 620c serves as a guiding block, while the other serves as a limiting groove that complements the guiding block. When it is necessary to detach the second housing from the first housing, one can grip the first housing and the second housing separately, rotate them in opposite directions to a certain position, and then pull in opposite directions. This causes the guiding block to disengage from the limiting groove, allowing the second housing to detach from the first housing. This enables the rapid and convenient disassembly of the battery component.

[0116] In embodiments, the first holder comprises the atomizing core base set inside the first housing 110, and the first connector 610c is placed on the base of the atomizing core. In embodiments, the first connector 610c serves as a guiding block, while the second connector 620c serves as a limiting groove. The guiding block can move along the limiting groove, and in the connected state of the first housing 110 and the second housing 120, the guiding block engages with the limiting groove. The guiding block is positioned on the base of the atomizing core and is arranged circumferentially along the base of the atomizing core. In a specific implementation, the guiding block is a protrusion extending along the circumferential surface of the base of the atomizing core in the direction away from the base of the atomizing core.

[0117] To prevent the guiding block from disengaging from the limiting groove, in embodiments, the guiding block can be configured as an elastic element. It is set in the width direction of the limiting groove, with the width of the guiding block being greater than the groove width of the limiting groove. This configuration allows the guiding block to be securely positioned within the limiting groove, preventing it from disengaging.

[0118] In another embodiment, a friction piece can be placed between the limiting groove and the guiding block to increase the friction force between them, preventing the guiding block from disengaging. In an implementation, the friction member can be a silicone component positioned between the limiting groove and the guiding block. Alternatively, it could be a rough surface located on the sidewall of the limiting groove. There is no specific restriction on the configuration, as long as it achieves the goal of increasing the friction force between the limiting groove and the guiding block.

[0119] Further referring to Figure 9, the limiting groove has an opening near one end close to the first housing. The guiding block can enter the limiting groove through the opening. In the connected state of the first housing 110 and the second housing 120, the guiding block engages in the limiting groove away from the end with the opening, preventing the guiding block from disengaging from the limiting groove.

[0120] In embodiments, the connecting component 600 further comprises at least one limiting member (not shown in the figure). The limiting member is positioned in the limiting groove away from the opening end and is located on any sidewall of the limiting groove. In a specific implementation, the limiting member extends along one sidewall of the limiting groove toward the other sidewall. The limiting member extends along the sidewall of the limiting groove away from the mouthpiece toward the other sidewall. The limiting member can be an independently connected part in the limiting groove or integrally formed with the limiting groove, and specific details are not specified here.

[0121] In the embodiment of this application, at least one of the guiding block or limiting member is an elastic element. The distance between the limiting member and the sidewall of the limiting groove it faces is smaller than the size of the guiding block in the width direction of the limiting groove. By setting the guiding block or limiting member as an elastic element and specifying that the distance between the limiting member and the sidewall of the limiting groove it faces is smaller than the size of the guiding block in the width direction of the limiting groove, on the one hand, it facilitates the guiding block to pass through the gap between the limiting member and the limiting groove, and on the other hand, it can restrict the guiding block in the limiting groove to prevent the guiding block from falling out of the limiting groove.

[0122] It is noted that, the specific shape of the guiding block is not limited. Any known shape can be used as the shape of the guiding block in this embodiment. For example, the guiding block can take any form, such as circular, square, rectangular, rhombic, trapezoidal, triangular, and polygonal shapes. Polygonal shapes include but are not limited to equilateral or non- equilateral pentagons, hexagons, octagons, and so on. The specific shapes are not exhaustively listed here.

[0123] In embodiments, the specific shape of the limiting groove is not limited, and the selection can be made based on the actual product requirements. In a specific implementation, the limiting groove can be composed of multiple interconnected groove sections, and the sections are set at an angle to facilitate confining the guiding block in one of the groove sections, preventing the guiding block from falling off. The limiting groove may comprise at least two interconnected parts, the first part and the second part, where the first part is set at an angle to the second part. The limiting groove may comprise a third part, the third part is set at one end away from the first part and is in communication with the second part, and the third part is set at an angle to the second part. In the connected state of the first housing and the second housing, the guiding block is engaged in the third part, preventing it from dislodging from the limiting groove.

[0124] Furthermore, the guiding block is an elastic element, and the width at the connection point between the third part and the second part is smaller than the width of the guiding block in the width direction of the second part. By setting the guiding block as an elastic element and specifying that the width at the connection point between the third part and the second part is smaller than the width of the guiding block in the width direction of the second part, it is not only convenient for the guiding block to pass through the gap between the limiting piece and the limiting groove but also further prevents the guiding block from dislodging from the limiting groove.

[0125] In embodiments, the limiting groove can be a spiral groove or an arc-shaped groove, and the spiral groove or arc-shaped groove is arranged along the circumferential direction of the second housing 120 on the second housing. This allows the guiding block to be rotated to the end of the spiral groove or arc-shaped groove away from the through groove by rotating, thereby restricting the guiding block in place.

[0126] It should be understood that the detachable structures achieved through the connecting components in embodiments one to three are just illustrative embodiments of the present disclosure and do not limit the scope of the present disclosure. As an illustrative implementation, the connection between the first housing 110 and the second housing 120 in this embodiment can also be achieved without the assistance of other components. In an embodiment, the first housing 110 and the second housing 120 can be removably connected by a nesting method. Specifically, the outer diameter of the end of the first housing near the second housing is set to be smaller than the outer diameter of the end of the second housing near the first housing, and a portion of the second housing is nested on the first housing. Alternatively, the outer diameter of the end of the first housing near the second housing is set to be larger than the outer diameter of the end of the second housing near the first housing, and a portion of the first housing is nested on the second housing. In another embodiment, the first housing and the second housing can also be connected by adhesive or threaded connection, and so on. Various methods can be employed, and the above examples are not exhaustive.
