Description

AEROSOL PROVISION SYSTEM

Technical Field

The present application relates to the field of aerosol provision technology, and particularly relates to an aerosol provision system.

Background

Currently, none of the e - cigarette products on the market provide a protective cover or any protective measures for the mouthpiece (the part that comes into contact with the user's mouth when inhaling). As a result, the mouthpiece is always exposed to the environment and is vulnerable to contamination by dust, oil stains, etc., which may even pose problems to the user's health. After use, a small number of e - cigarette products may be placed entirely in a storage bag or a container. Although this may, to some extent, help solve the hygiene problem of the mouthpiece, they may be also prone to contamination or getting dirty during transportation and storage. Moreover, the user needs to open the box and then take out the device by hand, which, to some extent, is not a very good user experience and affects the user experience. On the other hand, the e - cigarette industry also hopes to create more innovative and technologically - advanced products to provide users with different usage experiences.

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 aerosol- generating material without heating. For example, the aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

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.

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.

As shown in Figures 1-3, an embodiment provides an aerosol provision system 100, which comprises an upper housing 101 and a lower housing 102. The upper housing 101 and the lower housing 102 may be configured to be relatively movable along the height direction X between a first relative position as shown in Figure 1 and a second relative position as shown in Figure 3. Wherein, when the upper housing 101 and the lower housing 102 are in the first relative position as shown in Figure 1 , the aerosol provision system 100 is in a hygienic state; when the upper housing 101 and the lower housing 102 are in the second relative position as shown in Figure 3, the aerosol provision system 100 is in a puffing state.

Figure 2 shows an exploded perspective view of the aerosol provision system 100 in Figure 1. As shown in Figure 2, the top of the upper housing 101 may be provided with a first opening 1011 , and the lower housing 102 has an accommodating cavity 1021. The top of the accommodating cavity 1021 may be provided with a second opening (not labeled in the figure); the inside of the accommodating cavity 1021 may be used for placing a puffing component 104 with a mouthpiece 1041. Wherein, the projections of the first opening 1011 and the second opening in the height direction at least partially overlap, that is, the first opening 1011 can communicate with the accommodating cavity 1021 , so that the mouthpiece 1041 can extend out of the first opening 1011 or retract into the first opening 1011 when the upper housing 101 and the lower housing 102 move relatively.

It should be noted that the puffing component 200 with a mouthpiece may be a cigarette stick or a cartridge, which can be detachably installed within the aerosol provision system 100.

The distance between the top of the upper housing 101 and the bottom of the lower housing 102 when the upper housing 101 and the lower housing 102 are in the first relative position may be greater than the distance between the top of the upper housing 101 and the bottom of the lower housing 102 when the upper housing 101 and the lower housing 102 are in the second relative position.

As an embodiment, when the upper housing 101 and the lower housing 102 are in the first relative position and the second relative position, the upper housing 101 may be sleeved outside the lower housing 102, that is, as shown in Figures 1 and 3; or the upper housing 101 may be sleeved inside the lower housing 102. Such a configuration of the matching relationship between the upper housing 101 and the lower housing 102 enables the upper housing 101 and the lower housing 102 to be at least partially nested when moving towards each other along the height direction X of the aerosol provision system without interfering with each other. Wherein, when the upper housing 101 and the lower housing 102 are in the first relative position, the upper housing 101 and the lower housing 102 have an overlapping area of a first length along the height direction X, so that the puffing component 104 may be hidden inside the first opening 1011 ; when the upper housing 101 and the lower housing 102 are in the second relative position, the upper housing 101 and the lower housing 102 have an overlapping area of a second length along the height direction X, so that the puffing component 104 may extend out of the first opening 1011 , and the second length is greater than the first length.

It is to be understood that the upper housing 101 and the lower housing 102 may also be configured according to the following arrangements.

When the upper housing 101 and the lower housing 102 are in the first relative position, the length of the overlapping area of the upper housing 101 and the lower housing 102 along the height direction X is 0, that is, the first length is 0, and at this time, the puffing component 104 is still hidden inside the first opening 1011 ; when the upper housing 101 and the lower housing 102 are in the second relative position, the upper housing 101 and the lower housing 102 have an overlapping area of a second length along the height direction X, and at this time, the puffing component 104 extends out of the first opening 1011.

Alternatively, when the upper housing 101 and the lower housing 102 are in the first relative position, there is a first spacing distance between the bottom of the upper housing 101 and the top of the lower housing 102. When the upper housing 101 and the lower housing 102 are in the second relative position, there is a second spacing distance between the bottom of the upper housing 101 and the top of the lower housing 102, wherein the second spacing distance is less than the first spacing distance. In this way, the upper housing 101 and the lower housing 102 will not interfere with each other when moving towards each other along the height direction X of the aerosol provision system, affecting the movement of the puffing component 104.

Based on the structure of the above-mentioned aerosol provision system 10, during use, the user can apply a stress, such as a compressive stress or a tensile stress, to the upper housing 101 and/or the lower housing 102 to cause a relative movement between the upper housing 101 and the lower housing 102, so that the upper housing 101 and the lower housing 102 can be switched between the first relative position and the second relative position, making the aerosol provision system 10 in the hygienic state as shown in Figure 1 or in the puffing state as shown in Figure 3.

As a specific embodiment, when the aerosol provision system 10 is in the hygienic state, that is, when the upper housing 101 and the lower housing 102 of the aerosol provision system 10 are in the first relative position, the user can apply a compressive stress to the upper housing 101 to make the upper housing 101 move towards the direction close to the lower housing 102 until the upper housing 101 and the lower housing 102 are in the second relative position, and thus the aerosol provision system 10 is converted from the hygienic state to the puffing state;

When the aerosol provision system 10 is in the puffing state, the user can apply a tensile stress to the upper housing 101 to make the upper housing 101 move towards the direction away from the lower housing 102 until the upper housing 101 and the lower housing 102 are in the first relative position, and at this time, the aerosol provision system 10 is converted from the puffing state to the hygienic state; or, a further mechanism can be provided inside the aerosol provision system 10. When the user applies a compressive stress to the upper housing 101 again, it triggers the upper housing 101 to move towards the direction away from the lower housing 102, and the upper housing 101 and the lower housing 102 return to the first relative position, so that the aerosol provision system 10 is converted back to the hygienic state.

Further, when the upper housing 101 and the lower housing 102 move towards or away from each other along the height direction X, the puffing component 104 may remain stationary relative to the lower housing 102;

Alternatively, the puffing component 104 moves relative to the lower housing 102 as the upper housing 101 and the lower housing 102 move towards or away from each other. The moving direction of the puffing component 104 relative to the lower housing 102 may be the same as or opposite to the moving direction of the upper housing 101. Wherein, when the moving direction of the puffing component 104 is the same as that of the upper housing 101 , the moving speed of the puffing component 104 relative to the lower housing 102 is less than the moving speed of the upper housing 101 relative to the lower housing 102. The realization of these moving modes of the puffing component 104 may be achieved by setting a corresponding conversion structure to convert the relative movement or the movement away from each other of the upper housing 101 and the lower housing 102 into the movement of the puffing component 104.

Based on the above structure, as shown in Figure 4, the aerosol provision system may further comprise a movable cover body 103 for opening or closing the first opening 1011. By providing the cover body 103, after the user stops using the aerosol provision system 100 and hides the puffing component 104 inside the first opening 1011 , the first opening 1011 can be closed to further ensure the hygiene inside the aerosol provision system 100.

The movement of the cover body 103 between the open position and the closed position may be achieved in various ways. For example, by setting a transmission mechanism, the movement of the upper housing 101 and the lower housing 102 from the first relative position to the second relative position may be converted into the movement of the cover body 103, so that the user does not need to drive the cover body 103 additionally. A simpler structure may also be designed. For example, as shown in Figure 5, a cover body sliding groove 1031 may be provided at the top of the upper housing 101 , and the cover body 103 has a sliding member 1032 inserted into the cover body sliding groove 1031. In this implementation mode, the user may directly drag the cover body 103 to make the cover body 103 move between the open position and the closed position.

To facilitate user operation, the aerosol provision system 100 may further include a guiding component connected between the upper housing 101 and the lower housing 102 for guiding the movement of the upper housing 101 and the lower housing 102 from the first relative position to the second relative position.

As an implementation, the guiding component may adopt a Push-Push (push-type) structure, so that after the user applies a pressing action to at least one of the upper housing

101 and the lower housing 102 to make them in the first relative position. When the user applies a pressing action to at least one of the upper housing 101 and the lower housing 102 again, the upper housing 101 and the lower housing 102 may move from the first relative position to the second relative position.

The guiding component of the Push-Push (push-type) structure may have various implementation modes, which will be described in detail below in combination with specific drawings.

As shown in Figure 6, the guiding component 105 comprises a first guide rail 1051 and a sliding member 1052 that moves along the first guide rail 1051. Wherein, the first guide rail 1051 extends along the height direction X of the aerosol provision system 10, which is substantially consistent with the relative motion direction between the upper housing 101 and the lower housing 102, to guide the movement of the upper housing 101 and the lower housing

102 from the first relative position to the second relative position.

Wherein, one of the first guide rail 1051 and the sliding member 1052 may be disposed on the upper housing 101 , and the other may be disposed on the lower housing 102, that is, they are respectively disposed on different housings.

The guiding component 105 further comprises a locking portion 1054, and the locking portion 1054 may be used for stably retaining the upper housing 101 and the lower housing 102 in the second relative position. As an implementation, the locking portion 1054 comprises a locking guide portion 1055, and the locking guide portion 1055 comprises a second guide rail 1056 and a third guide rail 1057.

Referring to Figure 7, the first end 1056a of the second guide rail 1056 may be connected to the first end 1057a of the third guide rail 105, and the second end 1056b of the second guide rail 1056 and the second end 1057b of the third guide rail 1057 may be respectively connected to the first end 1051a of the first guide rail 1051 . Wherein, the locking portion 1054 further includes a locking groove 1058, and the first end 1056a of the second guide rail 1056 and the first end 1057a of the third guide rail 105 may be connected through the locking groove 1058.

The locking groove 1058 may be configured to be capable of accommodating the sliding member 1052 and has a locking position where the sliding member 1052 may be locked. When the sliding member enters the locking groove 1058 along the first guide rail 1051 along the first guide rail, it may be locked at the locking position A, or may be unlocked by disengaging from the locking position A under the action of an external force.

As shown in Figure 7, one side wall of the groove at the locking position A may be provided with a recessed area that is sunken relative to the surrounding positions, so that the sliding member 1052 may slide into and be locked in the recessed area.

In this embodiment, the second guide rail 1056, the locking groove 1058, and the third guide rail 1057 communicate with the first guide rail 1051 to form a continuous track, and may be all on the upper housing 101 or the lower housing 102. Correspondingly, the sliding member 1052 located on the lower housing 102 or the upper housing 101 may enter the second guide rail 1056, the locking groove 1058, and the third guide rail 1057 in sequence along the first guide rail 1051 and then return to the first guide rail 1051.

In order to ensure that the sliding member 1052 may move in a single direction along the above-mentioned movement track and will not deviate and slide to an undesired guide rail at the intersection of each guide rail, a one-way check structure may be provided at the intersection of each track. For example, a one-way check structure may be provided at one or respectively between the second guide rail 1056 and the locking groove 1058, between the locking groove 1058 and the third guide rail 1057, and between the third guide rail 1057 and the first guide rail 1051.

As an implementation, the one-way check structure may be constructed as a stepped surface to prevent the sliding member from moving upstream from downstream. As shown in Figure 7, a one-way check structure may be formed between the second guide rail 1056 and the locking groove 1058. The one-way check structure may be a stepped surface 1059a inclined towards the first end 1056a of the second guide rail 1056. The stepped surface 1059a forms an acute angle with the second guide rail 1056. When the sliding member 1052 travels to the first end 1056a of the second guide rail 1056, the stepped surface 1059a plays a guiding role, changing the movement of the sliding member 1052 from the movement along the height direction to the oblique movement, so that it falls into the locking position A of the locking groove 1058;

A one-way check structure may be also formed between the locking groove 1058 and the third guide rail 1057. The one-way check structure may be a stepped surface 1059b inclined towards the first end 1057a of the third guide rail 1057. The stepped surface 1059a forms an acute angle with the third guide rail 1057. When the sliding member 1052 is subjected to an external force at the locking position A of the locking groove 1058, the stepped surface 1059b plays a guiding role, driving the sliding member 1052 to move obliquely from the locking position A towards the first end 1057a of the third guide rail 1057, so as to enter the third guide rail 1057.

Similarly, a stepped surface 1059c inclined towards the first guide rail 1051 may also be provided between the third guide rail 1057 and the first guide rail 1051 as a one-way check structure. The stepped surface 1059c may be inclined towards the first end 1051a of the first guide rail 1051 , and may guide the sliding member 1052 located in the third guide rail 1057 into the first guide rail 1051.

Referring to Figure 7, the first guide rail 1051 and the second guide rail 1056 may be smoothly connected. For example, the second guide rail 1056 may be also set to extend along the height direction. Thus, the first guide rail 1051 and the second guide rail 1056 may be regarded as a straight track. As a result, the sliding member 1052 may move unidirectionally from the first guide rail 1051 to the second guide rail 1056 without moving backward into the third guide rail 1057. Of course, in order to ensure that the sliding member 1052 moves unidirectionally from the first guide rail 1051 to the second guide rail 1056, a one-way check structure, such as the aforementioned stepped surface, may also be provided between the first guide rail 1051 and the second guide rail 1056, and details will not be repeated here.

The first guide rail 1051 , the second guide rail 1056, the locking groove 1058, and the third guide rail 1057 of the guiding component 105 may be provided on the upper housing 101 , and the corresponding sliding member 1052may be provided on the lower housing 102. Or the first guide rail 1051 , the second guide rail 1056, the locking groove 1058, and the third guide rail 1057 of the guiding component 105 may be provided on the lower housing 102, and the sliding member 1052 may be provided on the upper housing 101.

As a specific implementation, as shown in Figure 8 and in combination with Figure 9, the upper housing 101 may be provided with an upper housing bracket 1012 extending towards the lower housing, and the lower housing 102 may be provided with a lower housing bracket 1022; the lower housing bracket 1022 has an extension portion 1022a extending towards the upper housing 101 and a support portion 1022b for carrying and fixing the puffing component 104. Wherein, the upper housing bracket 1012 and the extension portion 1022a of the lower housing bracket 1022 may be at least partially overlapped in the horizontal direction perpendicular to the height direction X of the aerosol provision system 10.

The first guide rail 1051 , the second guide rail 1056, the locking groove 1058, and the third guide rail 1057 of the guiding component 105 may be provided on the upper housing bracket 1012. One end of the sliding member 1052 may be fixed on the lower housing bracket 1022 and extends towards the upper housing bracket 1012; the sliding member 1052 includes a slider 1061 fixed on the extension portion 1022a of the lower housing bracket 1022 and a connecting rod 1062 with one end 1062a fixedly connected to the slider 1061 ; the other end 1062b of the connecting rod 1062 may be embedded in the track formed by the first guide rail 1051 , the second guide rail 1056, the locking groove 1058, and the third guide rail 1057, and may move along the above-mentioned single movement direction.

It should be noted that the above-mentioned first guide rail 1051 , second guide rail 1056, locking groove 1058, and third guide rail 1057 may also be provided on the lower housing bracket 1022, and the corresponding sliding member 1052 may be provided on the upper housing bracket 1021 , and details will not be repeated here.

In this embodiment, the guiding component 105 further comprises an elastic reset element, and the elastic reset element may be used for providing a resilience force to the sliding member 1052 to move towards the other position when moving to one of the first relative position and the second relative position.

Wherein, the elastic reset element extends along the height direction X, and one end of the elastic reset element may be connected to the upper housing 101 or the upper housing bracket 1012, and the other end may be connected to the lower housing 102 or the lower housing bracket 1022.

Continuing to refer to Figure 8 and Figure 9, in this embodiment, the elastic reset element may be a spring 1071 , the upper housing bracket 1012 comprises a slide rail 1072, the slider 1061 of the sliding member 1052 may be sleeved on the slide rail 1072, the spring 1071 extends along the height direction of the aerosol provision system 100. One end may be connected to the upper housing bracket 1012, and the other end may be connected to the slider 1061.

As another implementation, as shown in Figures 10-12, similar to the previous embodiment, the upper housing 10T may be provided with an upper housing bracket 1012' extending towards the lower housing 102', and the lower housing 102' may be provided with a lower housing bracket 1022'. The lower housing bracket 1022' has an extension portion 1022a' extending towards the upper housing 10T and a support portion 1022b' for carrying and fixing the puffing component 104'. Wherein, the upper housing bracket 1012' and the extension portion 1022a' of the lower housing bracket 1022' may be at least partially overlapped in the horizontal direction perpendicular to the height direction X of the aerosol provision system. The first guide rail 105T, the second guide rail 1056', the locking groove 1058', and the third guide rail 1057' of the guiding component 105' may be provided on the upper housing bracket 1012', and one end of the sliding member may be fixed on the lower housing bracket 1022' and extends towards the upper housing bracket 1012'.

The difference from the previous embodiment is that, in this embodiment, the sliding member may be composed of a connecting rod 1062'. One end of the connecting rod 1062' may be fixedly connected to the extension portion 1022a' of the lower housing bracket 1022', and the other end 1062a' of the connecting rod 1062' may be embedded in the track formed by the first guide rail 105T, the second guide rail 1056', the locking groove 1058', and the third guide rail 1057', and may move along the above-mentioned single movement direction.

In addition, in this embodiment, the spring 107T as an elastic reset element also extends along the height direction X of the aerosol provision system. The difference from the previous embodiment is that one end of the spring 107T is directly connected to the upper housing 10T, and the other end is directly connected to the lower housing bracket 1022'.

It should be noted that the elastic reset element is not limited to the above two setting modes. Those skilled in the art can reasonably set an elastic reset element with the same or equivalent function/effect according to specific product components.

Based on the foregoing embodiments and in combination with Figures 1 - 10, as shown in Figures 13a - 13c, the working process of the aerosol provision system 100 in this embodiment is shown.

Specifically, Figure 13a shows a partial perspective view of the aerosol provision system 100 in the hygienic state, Figure 13b shows a schematic view of the relative positions of the upper housing bracket 1012 and the lower housing bracket 1022 inside the aerosol provision system 100 in Figure 13a, and Figure 13c shows a schematic view of the cooperation of the internal guiding component of the aerosol provision system 100 in Figure 13a.

As shown in Figures 13a - 13c, the aerosol provision system 100 is in the hygienic state. At this time, the upper housing 101 and the lower housing 102 maintain the first relative position, and part of the upper housing 101 may be sleeved outside the lower housing 102. At this time, the overlapping area (not shown in the figure) in the height direction of the aerosol provision system 100 has a first length. The first length can be set according to the dimensions of each component of the actual product and may be any value greater than or equal to 0. The cover 103 closes the first opening 1011 at this time. The puffing component 104 may be located inside the first opening 1011 and may be accommodated in the accommodating cavity of the lower housing 102 and may be carried on the support portion 1022b of the lower housing bracket 1022. At this time, one end 1062b of the connecting rod of the sliding member 1052 in the guiding component 105 may be embedded in the first track 1051.

When the user starts to use the aerosol provision system 100, first, the cover 103 needs to be moved from the position closing the first opening 1011 to the position fully opening the first opening 1011 , and then at least one of the upper housing 101 and the lower housing 102 may be pressed to make the upper housing 101 and the lower housing 102 move towards each other and change from the first relative position to the second relative position.

Figure 14a shows a partial perspective view when the upper housing 101 and the lower housing 102 are in the second relative position, that is, when the aerosol provision system 100 is in the puffing state. Figure 14b shows a schematic view of the relative positions of the upper housing bracket 1012 and the lower housing bracket 1022 inside the aerosol provision system

100 shown in Figure 14a, and Figure 14c shows a schematic view of the cooperation of the internal guiding component of the aerosol provision system 100 in Figure 14a.

As shown in Figures 14a - 14c and referring to Figures 6 and 7, the relative movement of the upper housing 101 and the lower housing 102 may be guided by the guiding component 105. The sliding member 1052 slides along the first track 1051 and the second track 1056 until it slides to the locking position A of the locking groove 1058 and may be locked. At this time, the upper housing 101 and the lower housing 102 are in the second relative position, and the overlapping area (not shown in the figure) of the two housings in the height direction of the aerosol provision system 100 has a second length, and the second length is greater than the first length. When the upper housing 101 and the lower housing 102 are in the second relative position, since the sliding member 1052 is locked at the locking position A, the elastic reset element 1071 is compressed, and the reverse resilience force it provides will make the sliding member 1052 more firmly locked in the locking groove 1058.

Referring to Figures 13a - 14c and Figures 6 and 7, after the user finishes using the aerosol provision system 100, at least one of the upper housing 101 and the lower housing 102 may be pressed again. When the pressure applied by the user is greater than the resilience force of the elastic reset element 1071 , the sliding member 1052 may be unlocked and moves from the locking groove 1058 to the third guide rail 1057 in the aforementioned single movement direction. At this time, the user does not need to continuously apply stress such as pressure to at least one of the upper housing 101 and the lower housing 102. Under the action of the resilience force of the elastic reset element 1071 , the sliding member 1052 moves along the third guide rail 1057 into the first guide rail 1051 , so that the upper housing

101 and the lower housing 102 return from the second relative position to the first relative position. The user may move the cover to the position closing the first opening 101 , and the aerosol provision system 100 thus returns to the hygienic state as shown in Figure 13a.

Thus, in one or more technical solutions of the above - mentioned aerosol provision system, after the user finishes using it, the mouthpiece is kept from being polluted, and it is convenient to carry and use. The structure is simplified, and the user experience is improved.

In addition, the aerosol provision system 100 further comprises a controller and a power supply. Wherein, the controller may be used to control the power supply, thereby controlling the system heating.

It can be understood that the controller and the power supply may have various possible settings. The controller may be programmable. The power supply may be any suitable power supply, such as a DC voltage source. In one embodiment, the power supply may be a lithium - ion battery. Alternatively, the power supply may be a nickel - metal hydride battery, a nickel - cadmium battery, or a lithium - based battery, such as a lithium - cobalt, lithium - iron phosphate, or lithium - polymer battery.

The controller may be carried on a circuit board, such as a printed circuit board. The circuit board and the power supply may be respectively or jointly arranged inside the above - mentioned upper housing 101 and/or inside the accommodating cavity 1021 of the lower housing 102 according to the actual situation.

The aerosol provision system 100 further comprises a heating element. Wherein, the heating element may be a heating needle, a heating coil, or other deformed forms. And in some embodiments, the heating element may be integrated into the puffing component such as a cartridge.
