In some alternative embodiments, the susceptor is on one or either side of the material.

[0120] 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.

[0121] 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.

[0122] 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 aerosol-modifying agent may be provided in an aerosol-modifying agent release component, that is operable to selectively release the aerosolmodifying agent.

[0123] 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 aerosolmodifying agent may be in powder, thread or granule form. The aerosol-modifying agent may be free from filtration material.

[0124] An aerosol generator is an apparatus configured to cause aerosol to be generated from the aerosolgenerating 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 aerosolgenerating 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.

[0125] Figure 1 shows a non-combustible aerosol provision system 1 (which may hereinafter be referred to as the "system") comprising a consumable 100 and a non-combustible aerosol provision device 2 (which may hereinafter be referred to as the "device"). The non-combustible aerosol provision device 2 is configured to generate an aerosol from an aerosol precursor liquid contained in the consumable 100, as shall be described below in more detail. The non-combustible aerosol provision device 2 comprises a heating module 200 and a power and control module 300. In the example shown, the system 1 may be described as a modular system, with the consumable 100 constituting a first module, the heating module 200 constituting a second module, and the power and control module 300 constituting a third module. The device 2 may thus also be described as being modular, with the heating module 200 and the power and control module 300 constituting two modules of the device 2. As shown in Figure 2, the consumable 100, the heating module 200, and the power and control module 300 may be removably coupled to one another such that the device 2 and the system 1 can be assembled and disassembled. For example, the consumable 100 can be decoupled from the device 2 to remove the consumable 100 therefrom, for example to replace the consumable 100 after its contents has been used up. Similarly, the heating module 200 of the device 2 may be decoupled from the power and control module 300 of the device 2, for example if the heating module 200 or the power and control module 300 needs to be replaced or otherwise removed. Figure 3 shows an exploded view of the system 1, including exploded views of the consumable 100, the heating module 200, and the power and control module 300. Exploded views of the heating module 200 and the consumable 100 are further shown in Figures 4 and 5 respectively. As shown in Figure 4, the heating module 200 comprises an outer housing 201, which in the example shown comprises a generally cylindrical hollow tubular body, although it is also envisaged that the outer housing 201 may have any other suitable shape. An inner atomising core housing 203 is arranged with an atomising core support seal 204 concentrically inside the outer housing 201, with a seal 202, which may for example comprise a sealing ring. The inner atomising core housing 203 is configured to house an atomising core body 205 which comprises a receiving volume 216 configured to receive a heater 207 for generating an aerosol from an aerosol precursor liquid inputted into the device 2 from the consumable 100. Advantageously, the heater 207 is arranged in the heating module 200 rather than in the consumable 100, therefore when the consumable 100 is removed from the system 1 for disposal, for example because all of its aerosol precursor liquid has been used up so it is empty and needs to be replaced with another consumable 100, the same heater 207 can be used again with a further consumable, which avoids a heater or other aerosol generating device being disposed of as part of the consumable 100. Thus, the system 1 can reduce waste and can have a reduced environmental impact by negating, or at least reducing, the inadvertent disposal of heaters and other aerosol generating device elements. That is, advantageously, the aerosol generating device including the heater 207 does not need to be discarded when the consumable 100 needs to be replaced, thus decreasing the environmental footprint of the system 1, and reducing the cost, weight and environmental impact of the disposable consumable 100.

[0126] In the example shown, arranged on opposite sides of the heater 207 are a first body of absorbent material 209 and a second body of absorbent material 210. The first and second bodies of absorbent material 209, 210 are configured to absorb aerosol precursor liquid, to provide a wicking effect, and the heater 207 is then configured to heat the first and second bodies of absorbent material 209, 210 to generate an aerosol therefrom, as shall be discussed below in more detail.

[0127] An atomising core seal 206 is arranged adjacent to the heater 207, and below the heater 207 are arranged an atomising core bottom cover 218, an atomising core lower seal 211, a first bottom cover 212, and a second bottom cover 213. To provide an electrical connection between the heating module 200 and the power and control module 300, the heating module 200 may further comprise one or more electrical contacts such as one or more pogo pins 208 for example, which may be configured to be received in one or more mounting apertures 215 of the first bottom cover 212.

[0128] Referring now to Figure 5, the consumable 100 comprises a generally circular housing 101 which comprises a mouthpiece 101a for being received in the mouth of a user of the system 1 to deliver an aerosol thereto for inhalation thereof, and an intermediate portion 101b arranged between the mouthpiece 101a and a mating portion 101c. The mating portion 101c is configured to mate with the outer housing 201 of the heating module 200, as shall be described below in more detail. Inside the housing 101 there is defined a liquid storage volume 120 for containing an aerosol precursor liquid. In the example shown, the liquid storage volume 120 is empty, for illustrative purposes, and it is envisaged that the liquid storage volume 120 may contain the an aerosol precursor liquid, or it may be empty or partially full of aerosol precursor liquid and be suitable for filling and / or refilling with aerosol precursor liquid.

[0129] The housing 101 has an open end which may be arranged with a plurality of elements to contain and close off the liquid storage volume 120. For example, the consumable 100 may further comprise an first bottom cover 102, a first seal 103, a switch plate 104, a second seal 105, for example a sealing ring, and a second bottom cover 106. Although, it is envisaged that one or more other elements may be present in addition to or in replacement of one or more of the aforementioned elements, in order to close off the liquid storage volume 120. For example, the first bottom cover 102 and / or the first seal 103 may be removed. In the example shown, the switch plate 104 and the second bottom cover 106 together provide the functionality of selectively sealing and unsealing, or selectively obstructing and opening, a flow path or inlet or outlet between the consumable 100 and the heating module 200, to selectively provide for fluid communication between the consumable 100 and the heating module 200, as shall be described in more detail below.

[0130] In the example shown, the first bottom cover 102, the first seal 103, the switch plate 104, the second seal 105, and the second bottom cover 106 are all generally circular and are arranged to be generally concentric with one another and with the housing 101 relative to a central longitudinal axis 124 of the consumable 100. It is though envisaged that other shapes and geometric arrangements may also be possible, for example if the housing 101 were to not be of a generally circular shape, such as to have a quadrilateral or other polygonal prismatic profile for example. The first bottom cover 102, the first seal 103, the switch plate 104, the second seal 105, and the second bottom cover 106 may be coupled together in any suitable manner. For example, first engaging elements 108 of the housing 101 may be configured to engage with second engaging elements 109 of the pod first bottom cover 102 and / or with third engaging elements 118 of the second bottom cover 106. The first engaging elements 108 may for example be configured to protrude from an outer surface of the housing 101, and to be recessed on an opposite side thereof on an inner surface of the housing 101, such that they can engage with the second and / or third engaging elements 109, 118, and / or also so that they may engage with one or more L-shaped slots 214 of the heating module 200 as shall be described below.

[0131] Each of the first bottom cover 102, the first seal 103, the switch plate 104, the second seal 105, and the second bottom cover 106 comprises a central aperture, such that their concentric arrangement with one another provides for a continuous aperture therethrough, formed from the alignment of their respective apertures. In particular, in the example shown, the upper bottom aperture cover 102 comprises an first bottom cover aperture 110, the first seal 103 comprises a first seal aperture 112, the switch plate 104 comprises a switch plate aperture 114, the second seal 105 is generally annular and ring shaped with a corresponding empty space defined thereinside, and the second bottom cover 106 comprises a second bottom cover aperture 116. Accordingly, the aforementioned continuous aperture provided therethrough which is formed from the alignment of their aforementioned respective apertures, provides an aerosol flow path 121 through the second bottom cover 106, the second seal 105, and switch plate 104, the first seal 103, and the first bottom cover 102, as shown in Figure 5. In this manner, aerosol generated by the heating module 200 may flow upwards through the second bottom cover 106, the second seal 105, the switch plate 104, the first seal 103, and the first bottom cover 102, to the mouthpiece 101a.

[0132] As shown in Figures 6 and 7, the housing 101 of the consumable 100 further comprises an aerosol conduit 107, which in the example shown, comprises a generally cylindrical hollow tube arranged up through the centre of the liquid storage volume 122. Accordingly, in the example shown, the liquid storage volume 122 is generally annular, and the aerosol conduit 107 and the liquid storage volume 122 are fluidly isolated from one another - that is, they are not in fluid communication with one another. As shown in Figure 6, the aerosol conduit 107 comprises a first portion 107a and a second portion 107b, and in the example shown, wherein they are both generally cylindrical and hollow, the first portion 107a has a smaller diameter than the second portion 107b. The first portion 107a may be sized to correspond with the first seal aperture 112 of the first seal 103, and / or any of the other elements which close off the open end of the housing 101, for coupling and engagement therewith. The aerosol flow path 121 is arranged to extend up through the centre of the hollow tubular conduit 121. In this manner, aerosol can flow from the second bottom cover aperture 116 of the second bottom cover 106 all the way through to the mouthpiece 101a of the consumable 100. As such, aerosol produced by the heating module 200 can flow up through the consumable 100 to the mouth of a user for inhalation.

[0133] As aforementioned, each of the second bottom cover 106, the switch plate 104, the first seal 103, and the first bottom cover 102, comprises a respective aperture 116, 114, 112, 110, providing for the flow of aerosol therethrough along the aerosol flow path 121. Similarly, each of the second bottom cover 106, the switch plate 104, the first seal 103, and the first bottom cover 102 similarly comprises one or more ports for the flow of fluid between the consumable 100 and the heating module 200. In the example shown, each of the second bottom cover 106, the switch plate 104, the first seal 103, and the first bottom cover 102 comprises two ports. In the example described therein, one of said ports is configured to act as an inlet, and the other of said ports is configured to act as an outlet. However, it is also envisaged that alternatively both ports may be configured to act as inlets, or both ports may be configured to act as outlets. Indeed, it is also envisaged that each of the second bottom cover 106, the switch plate 104, the first seal 103, and the first bottom cover 102 may comprise any number of ports, for example one port configured to act as an inlet, an outlet, or both an inlet and an outlet, or any number of two or more ports, such as two, three, four or more ports. Each of the ports may be configured to act as an inlet, an outlet, or both an inlet and an outlet. The following description will discuss the example shown in which there is an inlet port and an outlet port, however it is to be understood that the following description is also applicable to other arrangements of ports. Furthermore, whilst in the example described above and in the following description, each of the second bottom cover 106, the switch plate 104, the first seal 103, and the first bottom cover 102 comprises one or more ports for the flow of fluid between the consumable 100 and the heating module 200, for example in the form of apertures therein, it is also envisaged that one or more of said ports may also be provided by coupling the heating module 200 to the consumable 100, after engaging, rotating and positioning the consumable 100 relative to the heating module 200. For example, one or more of the second bottom cover 106, the switch plate 104, the first seal 103, and the first bottom cover 102 may each comprise a piercable or otherwise penetrable material which may comprise for example a silicone membrane. One or more protruding elements (not shown) of the heating module 200, such as one or more needles for example, may then be configured to pierce said penetrable material to create one or more apertures therein, said one or more apertures comprising said ports, to provide an inlet and / or an outlet in the second bottom cover 106, the switch plate 104, the first seal 103, and / or the first bottom cover 102. As shown in Figure 8, the second bottom cover 106 comprises a first port 117a and a second port 117b, which may collectively be referred to as ports 117. Each of the ports 117 is in the form of a generally circular aperture. The second bottom cover aperture 116 is also in the form of a generally circular aperture. In the example shown, the two circular ports 117 are arranged to intersect with the circular shape of the second bottom cover aperture 116, to form a single overall aperture having the shape of three intersecting circles arranged in a row, the central circle being larger in diameter than the outer two circles. The second bottom cover aperture 116 is arranged concentrically around the aerosol conduit 107 such that the aerosol flow path 121 flows therethrough. Hence, a central portion of the second bottom cover aperture 116 through which the aerosol conduit 107 is arranged is in fluid communication with the aerosol flow path 121 and hence also the heating module 102 and the mouthpiece 101a. The ports 107 are in fluid communication with the liquid storage volume 120 of the consumable 100, to provide for fluid communication between the consumable 100 and the heating module 200, as described below in more detail.

[0134] In the example described herein, the first port 117a is configured to act as an outlet for the consumable 100, whilst the second port 117b is configured to act as an inlet for the consumable 100, although as described above other configurations for the ports 117 are also possible. The first port 117a comprises an outlet for the flow of aerosol precursor liquid out of the liquid storage volume 120 of the consumable 100 into the heating module 200 of the device 2. Conversely, the second port 117b comprises an inlet for the flow of air into the liquid storage volume 120 of the consumable 100 from the device 2. Advantageously, inputting air into the liquid storage volume 120 can balance the pressure therein, avoiding the creation of a vacuum, as aerosol precursor liquid simultaneously flows out of the liquid storage volume 120 via the first port 117a, so that the aerosol precursor liquid can freely flow out of the consumable by gravity. As described below, similarly to how the second bottom cover aperture 116, the switch plate aperture 114, the first seal aperture 112, and the pod first bottom cover aperture 110 are generally aligned to provide a flow path therethrough, similarly, there are corresponding aligned ports in the switch plate 104, the first seal 103, and the first bottom cover 102, to provide further flow paths therethrough.

[0135] The switch plate 104 comprises ports 115, which are also generally circular, and are configured to correspond with and be alignable with the ports 117 of the second bottom cover 106. In the example shown, there are two ports 115, one of which is configured to act as an outlet for the flow of aerosol precursor liquid out of the liquid storage volume 120 of the consumable 100 into the heating module 200 of the device 2, and the other of which is configured to act as an inlet for the flow of air into the liquid storage volume 120 of the consumable 100 from the device 2. Similarly, the first seal 103 comprises ports 113 and the first bottom cover 102 comprises ports 111. Likewise, one of the ports 113 and one of the ports 111 are configured to act as an outlet for the flow of aerosol precursor liquid out of the liquid storage volume 120 of the consumable 100 into the heating module 200 of the device, and the other one of the ports 113 and the other one of the parts 111 are configured to act as an inlet for the flow of air into the liquid storage volume 120 of the consumable 100 from the device. The ports 113 and the ports 111 are configured to correspond with and be alignable with the ports 117 and the ports 115.

[0136] In this manner, the corresponding and alignable ports 111, 113, 115, 117 which are configured as outlets 111, 113, 115, 117a can be in fluid communication with one another to provide an aerosol precursor liquid flow path 122 for the flow of aerosol precursor liquid out of the storage volume 120 of the consumable 100; and the corresponding and alignable ports 111, 113, 115, 117 which are configured as inlets 111, 113, 115, 117b can be in fluid communication with one another to provide an air flow path 123 for the flow of air into the storage volume 120 of the consumable 100, to balance the pressure therein. As shown in Figure 5, the aerosol flow path 121, the aerosol precursor liquid flow path 122, and the air flow path 123 are generally parallel to one another. The aerosol precursor liquid flow path 122 is generally in an opposite direction to the aerosol flow path 121 and the air flow path 123, which are configured generally in the direction of from the heating module 200 and the second bottom cover 106 towards the mouthpiece 101.

[0137] Turning now to Figure 11, the second bottom cover 106 and the switch plate 104 are configured to cooperate with one another to selectively seal or otherwise obstruct the aerosol precursor liquid flow path 122 and the air flow path 123, by selecting blocking off or otherwise obstructing the flow through one or more of the ports 111, 113, 115, 117. In the example shown, the ports 117 of the second bottom cover 106 and the ports 115 of the switch plate 104 are configured to be circular and of approximately the same diameter and radial positioning, hence they are alignable with one another. In the example described herein, the second bottom cover 106 is configured to be rotationally fixed relative to the housing 101, whilst the second bottom cover 106 and the housing 101 are configured to be together rotatable relative to the switch plate 104, about the central longitudinal axis 124 of the consumable 100. In this manner, the second bottom cover 106 can be rotated relative to the switch plate 104 to selectively bring the ports 117 out of alignment with the ports 115, such that the ports 117 and 115 are no longer aligned to provide a through hole therethrough, but instead such that the second bottom cover 106 is arranged to at least partially block or otherwise obstruct the ports 115. In this manner, at least a portion of the aerosol precursor liquid flow path 122 and the air flow path 123 can be obstructed, such that fluid is no longer able to freely flow out of and into the liquid storage volume 120 of the consumable 100. Whilst in the example described herein, the second bottom cover 106 is described as being rotationally movable relative to the switch plate 104 to bring the ports 117 and 115 out of alignment, it is also envisaged that alternatively, the switch plate 104 may conversely be rotationally movable relative to the second bottom cover 106. Alternatively, both the switch plate 104 and the second bottom cover 106 may be rotationally movable relative to one another. That is, it is envisaged that at least one of the switch plate 104 and the second bottom cover 106 may be rotationally movable relative to the other one of the switch plate 104 and the second bottom cover 106. For example, the switch plate 104 may be configured to be rotationally fixed relative to the housing 101, whilst the switch plate 104 and the housing 101 are configured to be together rotatable relative to the second bottom cover 106. Whilst in the example shown, the relative movement between the switch plate 104 and the second bottom cover 106 is described as being rotational movement, it is also envisaged that other geometries and movement directions may also be employed. For example, the relative movement between the switch plate 104 and the second bottom cover 106 may be linear, such as a sliding motion, or may be both linear and radial. Different geometries and relative movements are indeed possible, although the following discussion shall relate to the aforementioned example in which the second bottom cover 106 is rotationally fixed relative to the housing 101, and the second bottom cover 106 and the housing 101 can together be rotated relative to the switch plate 104.

[0138] Figures 8 to 10 sequentially show how the rotational movement of the second bottom cover 106 and the housing 101 relative to the switch plate 104 can cause the obstruction of the aerosol precursor liquid flow path 122 and the air flow path 123, by selectively blocking off the ports 115. Figure 8 shows a position in which the ports 115 and 117 are aligned with one another, such that the aerosol precursor liquid flow path 122 and the air flow path 123 are not blocked or otherwise obstructed, and aerosol precursor liquid and air respectively are free to flow therealong. Hence, in this position, the consumable 100 is in an "open" state, in which the ports 111, 113, 115, 117 can be in fluid communication with the heating module 200 of the device 2, for example when the consumable 100 is coupled to the heating module 200. Thus, in this position, when the consumable 100 is coupled to the heating module 200, aerosol precursor liquid is free to flow out from the liquid storage volume 120 along the aerosol precursor liquid flow path 122, and air is free to flow into the liquid storage volume 120 along the air flow path 123, to balance the pressure in the liquid storage volume 120. Figure 9 shows an intermediate position in which the ports 115 and 117 are partially misaligned, for example such that they overlap by approximately 50% rather than approximately 100% as in the position shown in Figure 8, such that the aerosol precursor liquid flow path 122 and the air flow path 123 are at least partially obstructed, to restrict the flow of aerosol precursor liquid out from and air into the liquid storage volume 120 of the consumable 100. To move the consumable between the positions shown in Figures 8 and 9, the housing 101 and the second bottom cover 106 can be rotated relative to the switch plate 104, the actuation of which shall be described below in conjunction with the device 2, such that the ports 117 are displaced relative to the ports 115.

[0139] Figure 10 shows a position in which the ports 115 and 117 are completely misaligned, for example such that they do not overlap. The first seal 103 and / or the first bottom cover 102 may be geometrically sized and configured to obstruct any portion of the ports 115 which remains visible through the second bottom cover aperture 116 if needed, depending on the relative geometries thereof. In any case, in the exemplary position shown in Figure 10, the ports 117 are in such a position as to not provide through holes with the ports 115, such that the aerosol precursor liquid flow path 122 and the air flow path 123 are obstructed or otherwise blocked, to prevent the flow of aerosol precursor liquid out from and air into the liquid storage volume 120 of the consumable 100. As aforementioned, it is envisaged that the relative movement between the second bottom cover 106 and the switch plate 104 may be rotational, linear, both rotational and linear, or any other type of relative movement; and that the second bottom cover 106 may be movable relative to the switch plate 104, or vice versa, or both the second bottom cover 106 and the switch plate 104 may both be movable relative to one another. In this manner, the switch plate 104 and / or the second bottom cover 106 may be referred to as a flow control member, such that the flow control member is movable to selectively seal and open the ports 111, 113, 115, 117. It is also envisaged that the flow control member may comprise any other suitable arrangement, for example any other suitable arrangement to provide for a first position in which one or more of the ports 111, 113, 115, 117 are sealed or otherwise obstructed, and a second position in which the ports 111, 113, 115, 117 are unobstructed and can provide for fluid communication between the consumable 100 and the device 2.

[0140] Turning back to the sequence of Figures 8 to 10, which when viewed in consecutive order show a clockwise rotational movement of the second bottom cover 106 and the housing 101 relative to the switch plate 104 to block off the aerosol precursor liquid and air flow paths 122, 123, conversely, the second bottom cover 106 and the housing 101 can be moved in an anticlockwise rotational movement to place the ports 115 and 117 back into alignment, to unblock the aerosol precursor liquid and air flow paths 122, 123. In this manner, the consumable 100 may be rotated in order to move it between a first position in which the aerosol precursor liquid and air flow paths 122, 123 are blocked, sealed or otherwise obstructed, and a second position in which the aerosol precursor liquid and air flow paths 122, 123 are not blocked, sealed, or otherwise obstructed, such that fluid may flow into and out of the liquid storage volume 120 of the consumable 100. The manner in which said rotation may be actuated, and the interface between the consumable 100 and the heating module 200, shall be described below.

[0141] Turning back to Figure 11, the switch plate 104 further comprises one or more switch plate coupling elements 119. In the example shown, there are two switch plate coupling elements 119, although it is envisaged that there may be any other suitable number of switch plate coupling elements 119, such as one, three, four, five, six or more switch plate coupling elements 119. In the example shown, the switch plate coupling elements 119 are each in the form of a generally circular or elliptical recess formed in the switch plate 104, although it is envisaged that the switch plate coupling elements 119 may have any other suitable form, and may each comprise for example a slot, other shaped recess, groove, channel, aperture, or pin. As shown in Figure 5, the second bottom cover aperture 116 of the second bottom cover 106 may be sized to have a larger diameter than the switch plate aperture 114 of the switch plate 104, such that both the ports 115 and the switch plate coupling elements 119 are visible through and unobstructed by the second bottom cover aperture 116, for example as shown in Figure 8. In this manner, regardless of the relative position between the switch plate 104 and the second bottom cover 106, the switch plate coupling elements 119 are always accessible and are never obstructed, as shown sequentially in Figures 8 to 10.

[0142] As shown in Figure 12, the heating module 200 comprises one or more engaging elements which are configured to engage with the switch plate coupling elements 119, to engage the device 2 and the consumable 100. In the example shown, the one or more engaging elements comprise generally cylindrical protruding pins 220 formed as part of the inner atomising core housing 203, although it is envisaged that the one or more engaging elements may be formed as any other part of the heating module 200, for example as part of the outer housing 201 or the seal 202. It is also envisaged that the one or more engaging elements need not necessarily be in the form of generally cylindrical pins 220 and may have any other suitable form, for example they may each comprise a slot, recess, groove, channel, aperture, or other shaped pin. The one or more engaging elements may be sized, shaped and positioned to correspond with the form and positioning of the switch plate coupling elements 119. In the example shown, there are two pins 220, however it is also envisaged that there may be any other suitable number of pins 220 and / or other engaging elements, such as one, three, four, five, six or more pins 220 or other engaging elements.

[0143] The generally cylindrical pins 220 are configured to be received in and hence engage with the generally circular recessed switch plate coupling elements 119, to engage the switch plate 104 of the consumable 100 with the heating module 200. As described above, in the example shown, the second bottom cover 106 and the housing 101 of the consumable 100 are together rotatable relative to the switch plate 104, and by engaging the switch plate 104 with the heating module 200 via the pins 220 and switch plate coupling elements 119, the consumable 100 can thus be rotated relative to the heating module 200, during which said rotation, the switch plate 104 will remain rotationally fixed or stationary relative to the heating module 200. That is, when pins 220 are received in the switch plate coupling elements 119, rotating the second bottom cover 106 and the housing 101 of the consumable 100 relative to the heating module 200 and hence relative to the device 2, will cause the switch plate 104 to remain relatively stationary with the heating module 200. In this manner, the consumable 100, specifically in the example described herein, the second bottom cover 106 and the housing 101 thereof, can be rotated relative to the heating module 200 to move the second bottom cover 106 and the switch plate 104 between the first position in which the aerosol precursor liquid flow path 122 and the air flow path 123 are sealed, and the second position in which they are not sealed or obstructed, and the liquid storage volume 120 is thus free to be in fluid communication with the heating module 200. Thus, by engaging the pins 220 and the switch plate coupling elements 199, the consumable 100 can be moved relative to the heating module 200 between the positions shown in Figures 8 and 10, to selectively seal / block and unseal / unblock the aerosol precursor liquid and air flow paths 122 and 123 and the ports 111, 113, 115, 117.

[0144] In the present example, all of the first bottom cover 102, first seal 103 and second bottom cover 106 rotate together relative to the switch plate 104.

[0145] In order to fixedly couple the consumable 100 to the heating module 200 of the device 2, and to accurately provide for the actuation of movement between the aforementioned first and second positions of the second bottom cover 106 relative to the switch plate 104, the outer housing 201 of the heating module 200 comprises one or more locking elements 214, which in the example shown in Figure 12 comprises four slots 214. Although, it is also envisaged that the one or more locking elements 214 may have any other suitable form, for example they may each comprise a groove, recess, channel, aperture, or pin, and that there need not be four such locking elements, and there may indeed be any other suitable number of locking elements, such as one, two, three, five, six or more such locking elements. In the example shown, the four slots 214 are arranged to be generally equally spaced apart from one another about the circumference of the outer housing 201, which in the example shown is generally cylindrical and is configured to be generally coincident with and centred on the longitudinal axis 124 of the consumable 100. Each of the slots 214 is generally L shaped and comprises a longitudinal portion 214a arranged to be generally parallel to the longitudinal axis 124, and a generally perpendicular circumferential portion 214b arranged to be generally parallel to the circumference of the outer housing 210.

[0146] Turning back to Figure 6, correspondingly, the aforementioned first engaging elements 108 of the housing 101 of the consumable 100 may be configured to engage with the slots 214 or other form of locking elements 214. In the example shown, each of the first engaging elements 108 is generally rectangular and arranged parallel to the circumference of the housing 101, and is sized and shaped to be receivable in a respective one of the slots 214. Figures 13 to 18 sequentially show how the consumable 100 may be coupled to the heating module 200 and locked thereto, by exemplary means of the first engaging elements 108 and the slots 214.

[0147] Figure 13 shows the consumable 100 in a position in which it is not coupled to the heating module 200. As shown in Figure 14, to couple the consumable 100 to the heating module 200, the consumable 100 can be brought closer to the heating module 200, such that each of the first engaging elements 108 is arranged to be aligned with a respective one of the L-shaped slots 214. Next, the consumable 100 may be moved further towards the heating module 200 along the direction of the longitudinal axis 124, such that each of the first engaging elements 108 is slid down the longitudinal portion 214a of the respective L-shaped slot 214, to the position shown in Figure 15. In this position, the consumable 100 is placed in contact with the heating module 200 and the pins 220 are received with and engaged with the switch plate coupling elements 119. In this position, the second bottom cover 106 is arranged such that its ports 117 are not generally aligned with the ports 115 of the switch plate 104, such that the ports 115 are obstructed / sealed, hence the aerosol precursor liquid and air flow paths 122, 123 are sealed blocked. Thus, aerosol precursor liquid is unable to flow out of any of the ports 111, 113, 115, 117 into the heating module 200 in this state, thus inadvertently avoiding any unwanted leakage of aerosol precursor liquid. Fluid communication between the consumable 100 and the heating module 200 is undesirable and is hence prevented in this position, because in this position, the consumable 100 is not yet locked in place on the heating module 200, and it could inadvertently be decoupled therefrom, by linear movement of the first engaging elements 108 in the longitudinal portions 214a of the L-shaped slots 214. Thus, in the state shown in Figure 15, the consumable 100 may be described as being in an "unlocked" position relative to the heating module 200. As described above, this corresponds with a "sealed" position of the second bottom cover 106 and the switch plate 104, that is the "first position" described above, which is shown for example in Figure 10.

[0148] Next, in order to fixedly couple the consumable 100 to the heating module 200, the consumable 100 can be rotated relative to the heating module 200, as sequentially shown between Figures 15 and 16, to move each of the first engaging elements 108 circumferentially along the circumferential portion 214b of the respective L-shaped slot 214 of the heating module 200. As shown in Figure 17, the consumable 100 can be further rotated relative to the heating module 200 to move the first engaging elements 108 further along the circumferential portions 214b. Figure 18 shows a locked position of the consumable 100 on the heating module 200 in which the first engaging elements 108 are at a position of maximum circumferential displacement along the circumferential portions of the slots 214b, such that they cannot be moved any further therealong. In this position, the first engagement elements 108 cannot inadvertently move up the longitudinal portions 214a of the slots 214 to decouple the consumable 100 from the heating module 200, without first rotating the consumable 100 back in the opposite direction to reference the aforementioned steps, taking the consumable 100 back in reverse through the positions sequentially shown in Figures 18 back to 14. Thus, in the state shown in Figure 18, the consumable 100 may be described as being in a "locked" position relative to the heating module 200. This corresponds with an "unsealed" position of the second bottom cover 106 and the switch plate 104, that is the "second position" described above, which is shown for example in Figure 8.

[0149] Thus, in this manner, by rotating the consumable 100 relative to the heating module 200, the aerosol precursor liquid and air flow paths 122, 123 can be selectively sealed and unsealed, to selectively provide for fluid communication between the consumable 100 and the heating module 200 when the consumable 100 is fixedly coupled to and locked in place on the heating module 200, and to then prevent said fluid communication to avoid leakage when the consumable 100 is not fixedly coupled to the heating module 200, for example when the consumable 100 is being fitted to or removed from the device 2 before or after its consumption. Advantageously, the relative movement between the second bottom cover 106 and the switch plate 104, which in the example described herein is rotational movement, is automatically actuated by the fitting and removal of the consumable 100 onto the heating module 200, such that the liquid storage volume 120 of the consumable 100 is automatically sealed and unsealed as required without any additional action or interference required by the user of the system 1. Whilst in the example described above in conjunction with Figures 13 to 18, it is demonstrated that the consumable 100 may be rotated relative to the heating module 200 of the device 2 to couple it thereto, it is also envisaged that alternatively, the heating module 200 and / or another part of the device 2 may be rotated relative to the consumable 100 to couple it thereto. That is, it is relative movement between the consumable 100 and the heating module 200 which couples the consumable 100 and the heating module 200 together, and said relative movement may comprise rotational, linear, both rotational and linear, or any other relative movement, said relative movement comprising movement of the consumable 100, movement of the heating module 200, or simultaneous or sequential movement of both the consumable 100 and the heating module 200.

[0150] Accordingly, during use of the system 1, when the consumable 100 is fixedly coupled, for example locked as described above, to the heating module 200 of the device 2, for example as shown in the cross-sectional view of Figure 21, the second bottom cover 106 and the switch plate 104 are in the aforementioned second position, such that aerosol precursor liquid is permitted to flow through the ports 111, 113, 115, 117a, such that the aerosol precursor liquid flow path 122 is not sealed or obstructed and provides for fluid communication between the consumable 100 and the heating module 200, such that aerosol precursor liquid can be supplied to the first and second bodies of absorbent material 209, 210, to be heated by the heater 207 to generate an aerosol therefrom. As shall be described below in more detail, conversely, air is permitted to flow from the heating module 200 into the liquid storage volume 120 of the consumable 100, and aerosol generated by the heater 207 is configured to flow up through the centre of the consumable 100 through the aerosol conduit 107 along the aerosol flow path 121, for delivery of aerosol to the mouthpiece 101a for inhalation by a user of the system 1, from the heater 207 via an aerosol aperture 219 in the inner atomising core housing 203 as shown in Figure 12. Examples of these different flow paths 121, 122 and 123 are illustrated in Figure 21.

[0151] As aforementioned, it may be advantageous to supply air into the liquid storage volume 120 via the air flow path 123, whilst aerosol precursor liquid is simultaneously flowing out of the liquid storage volume 120 for consumption, in order to balance the pressure in the liquid storage volume 120 of the consumable 100. In the example shown, said air for flow along the air flow path 123 can be provided by one or more air conduits 217, which as shown in Figure 4, may for example comprise one or more slots, grooves or channels. The air conduits 217 may comprise a plurality of generally parallel channels and / or may form a labyrinth arrangement. The air conduits 217 may for example be in fluid communication with one or more air ports (not shown) formed in the outer housing 201 of the heating module 200, for inputting ambient external air into the device 2. The air conduits 217 may be configured to supply air not only into the air flow path 123 for balancing the pressure in the liquid storage volume, but also into the aerosol precursor liquid flow path 122 and / or into a region of the receiving volume 216 adjacent to the heater 207, for mixing with the aerosol generated thereby, such that the fluid flowing up the aerosol flow path 121 may comprise aerosol mixed with air.

[0152] As aforementioned, the device 2 further comprises a power and control module 300, exemplary elements of which are shown in the exploded view of Figure 3, and the cross-sectional view of Figure 21. The power and control module 300 can be coupled to and removed from the heating module 200, for example to provide for the removal and replacement of the heating module 200 and / or the power and control module 300 of the device 2, to avoid the entire device 2 having to be disposed of and replaced in the event of end of life of the heater 207 and / or the battery 303 for example, thus reducing wastage and the environmental impact of the system 1.

[0153] The power and control module 300 comprises a housing 301, which in the example shown is generally cylindrical and is configured to form a generally cylindrically bodied device 2 together with the outer housing 201 of the heating module 200. Arranged concentrically inside the housing 301 is a power supply, which in the example described herein comprises a battery 303, although it is envisaged that any other suitable power supply may be employed. The battery may for example be a rechargeable battery. A seal 302 is arranged to prevent the inadvertent leakage and ingress of aerosol precursor liquid and aerosol from the heating module 200 into the power and control module 300. The seal 302 may for example comprise a ring seal, for example comprising silicone. A further seal, bottom cover seal 304, may be arranged at an opposite end of the power and control module 300, to prevent ingress of moisture, debris and other foreign objects or fluids into the power and control module 300 from externally to the device 2. A circuit board 306 can also be provided, for controlling the battery 303 and the charging thereof. A bottom cover 308 forms a base of the power and control module 300, closing off an open end of the housing 301. If the battery 303 or other power supply is rechargeable, the bottom cover 308 may comprise a charging port (not shown), for receiving a charging cable, for example a charging cable comprising a USB-C type connector, to charge the power supply such as the battery 303. A charging port seal 307 may be arranged to seal the charging port from ingress and foreign debris. One or more fixing elements such as one or more screws 305 may be arranged to fix the circuit board 306 to the bottom cover 308. As described above, the consumable 100 may be coupled to and decoupled from the heating module 200, such that advantageously, the consumable 100 may be removed and replaced when desired, for example once the contents of the aerosol precursor liquid in the liquid storage volume 120 of the consumable has all been used up such that the liquid storage volume 120 is empty, or if the user wishes to change the consumable 100 to one containing a different aerosol precursor liquid, such as one containing a different flavour and / or active ingredient. Similarly, in order to provide that the modules of the device 2 may be removed and replaced as required, for example to replace the heating module 200 or the power and control module 300 in the event of the heater 207 or the battery 303 needing to be replaced for example, the heating module 200 and the power and control module 300 can similarly be coupled to and decoupled from one another. For example, Figures 19 and 20 show that the system 1 may be disassembled so that the heater 207 may be removed from the heating module 200 for replacement thereof.

[0154] In order to removably couple the power and control module 300 to the heating module 200, similarly to the L-shaped slots 214 and first engaging elements 108 described above in relation to the coupling of the consumable 100 to the heating module 200, a similar coupling means may also be employed between the power and control module 300 and the heating module 200. Although it is envisaged that other different coupling means may also be employed, for the sake of example, the following exemplary coupling means is described. As shown in Figure 20 for example, the outer housing 201 of the heating module 200 may comprise the L-shaped slots 214 at a relatively upper end thereof, proximal to the consumable 100, and may also comprise further L-shaped slots 221 at a relatively lower end thereof, proximal to the power and control module 300. Correspondingly the housing 301 of the power and control module 300 may comprise corresponding engaging elements 309, which may for example comprise generally rectangular protruding elements each configured to be received in and to slide within a respective one of the L-shaped slots 221. The engaging elements 309 may be configured to be received in and slide within the L-shaped slots 221 in substantially the same manner as the first engaging elements 108 and the L-shaped slots 214 as described above and exemplified sequentially in Figures 13 to 18.

[0155] As shown in Figure 20, the L-shaped slots 221 may be arranged to be generally in an opposite direction circumferentially around the device 200 compared with the L-shaped slots 214. For example, the L- shaped slots 214 and 221 may be configured such that relative to the orientation in the example shown in Figure 20, the consumable 100 may be rotated clockwise relative to the heating module 200 to couple it thereto and lock it in place. Conversely, the power and control module 300 may be rotated anticlockwise relative to the heating module 200 to couple it thereto and lock it in place. In this manner, inadvertent decoupling and unlocking of the consumable 100 relative to the heating module 200 may be avoided when coupling and decoupling the power and control module 300, and conversely, inadvertent decoupling and unlocking of the power and control module 300 relative to the heating module 200 may be avoided when coupling and decoupling the consumable 100. In this manner, the power and control module 300 can be mechanically coupled and fixedly connected to the heating module 200, to assemble the device 2.

[0156] In terms of the electrical connection between the power and control module 300 and the heating module 200, such that the battery 302 is able to supply power to the heater 207, this can be provided by the aforementioned one or more pogo pins 208 which are shown in Figure 22 for example, which shows the consumable 100 coupled to the heating module 200, with the outer housing 201 removed for illustrative purposes only. It is though also envisaged that any other suitable electrical connection may be employed instead of or in addition to one or more pogo pins 208.

[0157] In the above example, when the consumable 100 is fixedly coupled, for example locked as described above, to the heating module 200 of the device 2, for example as shown in the cross-sectional view of Figure 21, the second bottom cover 106 and the switch plate 104 are in the aforementioned second position, such that aerosol precursor liquid is permitted to flow through the ports 111, 113, 115, 117a, such that the aerosol precursor liquid flow path 122 is not sealed or obstructed and provides for fluid communication between the consumable 100 and the heating module 200, such that aerosol precursor liquid can be supplied to the first and second bodies of absorbent material 209, 210, to be heated by the heater 207 to generate an aerosol therefrom. In an alternative embodiment (not shown), the consumable may instead comprise an outlet with a sealing member (e.g. a plug or label) that is manually removed by the user prior to the consumable being connected to the heating module of the device.
