In some alternative embodiments, the susceptor is on one or either side of the material.
A consumable is an article comprising or consisting of an aerosol-generating material, part or all of which is intended to be consumed by a user during use. The consumable may comprise one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material delivery component, an aerosol-generating area, a housing, a wrapper, a mouthpiece, a filter, and/or an aerosol modifier. The consumable may also comprise an aerosol generator, such as a heater, which in use releases heat to cause the aerosol-generating material to generate an aerosol. The heater may for example comprise a combustible material, a material which is heatable by electrical conduction, or a susceptor.
A susceptor is a material that can be heated by penetration with a varying magnetic field (e.g., an alternating magnetic field). The susceptor may be an electrically conductive material such that its penetration by a varying magnetic field results in inductive heating of the heating material. The heating material may be a magnetic material such that penetration thereof by a varying magnetic field results in hysteresis heating of the heating material. The susceptor may be electrically conductive and magnetic such that the susceptor may be heated by two heating mechanisms. The device configured to generate a varying magnetic field is referred to herein as a magnetic field generator.
An aerosol-modifying agent is a substance typically located downstream of the aerosol-generating region that is configured to modify the generated aerosol, for example by altering the taste, flavor, acidity or another characteristic of the aerosol. The aerosol modifier may be disposed in an aerosol modifier release member operable to selectively release the aerosol modifier. For example, the aerosol modifier may be an additive or an adsorbent. For example, the aerosol modifiers may include one or more of fragrances, colorants, water, and carbon adsorbents. For example, the aerosol modifier may be a solid, a liquid, or a gel. The aerosol modifier may be in powder, wire or particulate form. The aerosol modifier may be free of filter material.
An aerosol generator is a device configured to cause the generation of an aerosol from an aerosol-generating material. In some embodiments, the aerosol generator is a heater configured to subject the aerosol-generating material to thermal energy in order 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 generation of an aerosol 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 vapor delivery systems), such as nebulizers or e-cigarettes. In the following description, the term "e-cigarette" or "e-cigarette" may be used at times, but it will be understood that this term may be used interchangeably with aerosol delivery system/device and electronic aerosol delivery system/device. Furthermore, as is common in the art, the terms "aerosol" and "vapor" and related terms such as "evaporation," "aerosolization," and "aerosolization" are often used interchangeably.
Aerosol delivery systems (e-cigarettes) typically, although not always, comprise a modular assembly comprising a reusable device portion and replaceable (disposable/consumable) cartridge components. Typically, the replaceable cartridge component will include an aerosol-generating material and a vaporiser (which may be collectively referred to as a "vaporiser"), and the reusable device portion will include a power supply (e.g. a rechargeable power supply) and control circuitry. It will be understood that these different parts may include additional elements depending on the function. For example, the reusable device portion will typically include a user interface for receiving user input and displaying operating status features, and the replaceable cartridge device portion in some cases includes a temperature sensor for helping control temperature. The cartridge is electrically and mechanically coupled to the control unit for use, for example using threads, bayonet or magnetic coupling with suitably arranged electrical contacts. When the aerosol-generating material in the cartridge is exhausted, or when the user wishes to switch to a different cartridge having a different aerosol-generating material, the cartridge may be removed from the reusable component and a replacement cartridge attached in its place. Systems and devices conforming to this type of two-piece modular configuration may generally be referred to as two-piece systems/devices.
Electronic cigarettes typically have a generally elongated shape. To provide a specific example, some embodiments of the present disclosure will be considered to include such a generally elongated two-piece system employing disposable cartridges. However, it will be appreciated that the basic principles described herein may equally be applied to different configurations, such as single-piece systems or modular systems comprising more than two parts, refillable devices and single-use disposable articles, as well as other general shapes, for example based on so-called box-mode high performance devices that typically have a box-like shape. More generally, it will be understood that certain embodiments of the present disclosure are based on aerosol delivery systems that are operatively configured to provide functionality in accordance with the principles described herein, and that the constructional aspects of the system configured to provide functionality in accordance with certain embodiments of the present disclosure are not of primary importance.
As described in the background, for heating a non-combustible aerosol supply (THP), conventional methods of testing the temperature field of a cigarette have focused on testing the temperature of the heater itself. In practice, the temperature of the heating element does not fully reflect the temperature inside the cigarette. The heating mode, the distance between the heating element and the air passage and the like can influence the temperature of the actual cigarette. The temperature field of the cigarettes is a direct factor affecting the taste. Therefore, the conventional method of testing the temperature field of cigarettes is not sufficient to evaluate how good the taste is with THP devices. If the thermocouple is to be inserted into the actual cigarette, the problem that the thermocouple is difficult to locate is faced. To eliminate the effects of the variables, a large number of samples are required for testing, which undoubtedly increases the cost of the cigarette test considerably.
In view of one or more of the above problems, embodiments of the present application creatively provide a non-consumable simulated cigarette, which has a similar structure, thermodynamic properties, resistance to smoking, etc. to a cigarette and is reusable. The simulated cigarette at least comprises a simulated section for simulating an atomized material, on one hand, the first temperature measuring elements are distributed in the simulated section in a space lattice mode, so that the temperature change of the simulated section can be tested, the test requirement is met, and on the other hand, the test stability and the repeatability can be improved.

Fig. 1 is a schematic perspective view of a non-consumable simulated cigarette according to an embodiment of the present application, fig. 2 is a cross-sectional view of a non-consumable simulated cigarette according to an embodiment of the present application, and fig. 3 is an exploded view of a non-consumable simulated cigarette according to an embodiment of the present application, and generally includes a simulation section 100, a cooling section 200, a filter section 300, a housing 400, a temperature measuring element, and the like, as shown with reference to fig. 1 to 3. The housing 400 has a hollow hole 410 formed therein, and the analog section 100, the cooling section 200, the filter section 300, the temperature measuring element, and the like are accommodated in the hollow hole 410. The simulation section 100 is used to simulate the atomized material and the process of heating the atomized material without consumption. The cooling section 200 is used to simulate the cooling process of an aerosol and the filter section 300 is used to simulate the filter of a cigarette. The temperature measuring element comprises a plurality of temperature measuring elements which are respectively used for detecting the temperatures of different parts in the simulated cigarette. In some specific embodiments, the temperature sensing element includes a first temperature sensing element 510, the first temperature sensing element 510 being configured to sense the temperature of the analog segment 100.
It should be noted that, the non-consumption of the non-consumption simulated cigarette provided by the embodiment of the application means that no atomized material is consumed in the heating process. Wherein, the atomized material can form aerosol for sucking by a user after being heated. Atomized materials include tobacco-containing, tobacco-free, but nicotine-containing, and tobacco-free and nicotine-free materials, without specific limitation. It will be appreciated that certain components of the simulated cigarette undergo some change in physical properties as the number of uses increases, so that the relevant components may be replaced if desired.
It should be noted that, in the embodiment of the present application, the shape of the analog segment 100 is not specifically limited, and may be set according to the actual product requirement during the implementation, and the product is an exemplary but non-limiting illustration, and the analog segment 100 may have a cylindrical shape, so that its structure is similar to that of the aerosol material of the cigarette.
Referring to fig. 3, the analog segment 100 is provided with a plurality of detection positions, and each detection position is provided with a first temperature measuring element 510. In a preferred embodiment of the present application, the detection positions include at least one first detection position 610 and at least one second detection position 620, where the first detection position 610 is located on the outer peripheral wall of the cylindrical analog segment 100, and the second detection position 620 is closer to the central axis of the cylindrical analog segment 100 than the first detection position 610, so that the first detection position 610 and the second detection position 620 are distributed in the analog segment 100 in a space lattice manner, and thus the first temperature measuring element 510 is distributed in the analog segment 100 in a space lattice manner, so that the first temperature measuring element 510 can test the temperature changes in all directions of the analog segment 100, so as to meet the test requirement.
In a preferred embodiment of the present application, the analog segment 100 is provided with a mounting structure 110, and the mounting structure 110 extends from one end to the other end in the axial direction of the analog segment 100. The first temperature sensing element 510 may extend from the mounting structure 110 and reach a designated sensing location.
It will be appreciated that common heating non-combustion aerosol provision devices (THP) include both central heating and circumferential heating modes. In the embodiment of the present application, a simulated cigarette for a central heating type heating non-combustion aerosol supply device (THP) is taken as an example, and the scheme of the present application will be described. For a central heating type heating non-combustion aerosol supply device (THP), a heating needle of the device needs to be inserted into an atomized material section (corresponding to a simulation section of a simulation cigarette) of the cigarette for heating, so that a temperature measuring element cannot be installed at the central axis position of the atomized material section (corresponding to the simulation section of the simulation cigarette). For the above reasons, referring further to fig. 3 and 4, the simulated cigarette further includes a circumferential support 700, the circumferential support 700 is sleeved outside the simulated section 100, an axial groove 710 is formed on an inner wall surface of the circumferential support 700, and the first detection position 610 is located in the axial groove 710. The mounting structure 110 comprises at least a mounting groove 111, wherein the mounting groove 111 is located at the outer circumferential wall of the analog segment 100 and extends in the axial direction, and the second detection position 620 is located in the mounting groove 111. It will be appreciated that the mounting slot 111 is closer to the central axis of the analog segment 100 than the axial slot 710. Each of the first detection position 610 and the second detection position 620 is provided with a first temperature measuring element 510.
In a preferred embodiment of the present application, ribs 720 are further disposed on the inner wall surface of the circumferential support 700, and the ribs 720 protrude toward the simulation section 100 on the inner wall surface of the circumferential support 700, and the ribs 720 are inserted into the mounting grooves 111 to assist in fixing the first temperature measuring element 510. Preferably, the rib 720 is provided with a groove 721, and the groove 721 cooperates with the mounting groove 111 to form a receiving space for receiving the first temperature measuring element 510 and define the first temperature measuring element 510 in the receiving space.
It will be appreciated that, in order to achieve the spatial lattice distribution of the first detection positions 610 and the second detection positions 620 at the analog segment 100, referring to fig. 5, the first detection positions 610 and the second detection positions 620 in the embodiment of the present application each include a plurality of first detection positions 610 and second detection positions 620 that are spaced apart along the axial direction of the analog segment 100 in the axial slot 710, and a plurality of second detection positions 620 that are spaced apart along the axial direction of the analog segment 100 in the mounting slot 111. With further reference to FIG. 5, as an exemplary and non-limiting illustration, assuming that the first detecting locations 610 include A1, B1, C1 and the second detecting locations 620 include A2, B2, C2, it will be appreciated that a first temperature measuring element 510 is disposed at each of the first detecting locations 610 and the second detecting locations 620. The heating depth and the heating efficiency of the aerosol provision device for the simulation segment 100 at a fixed height can be evaluated by radial temperature gradients (A1, A2), (B1, B2), (C1, C2) and time variations, and the heating uniformity of the aerosol provision device for the simulation segment 100 in the axial direction and the influence of the air passage on the temperature of the simulation segment 100 can be evaluated by axial temperature gradients (A1, B1, C1), (A2, B2, C2) and time variations.
Further preferably, the mounting groove 111 includes a plurality of mounting grooves 111 arranged at intervals along the circumferential direction of the analog segment 100 at the outer circumferential wall of the analog segment 100. The plurality of axial grooves 710 are provided on the inner wall surface of the circumferential bracket 700, and the plurality of axial grooves 710 are arranged at intervals in the circumferential direction of the circumferential bracket 700 on the inner wall surface of the circumferential bracket 700.

It should be noted that, in the embodiment of the present application, the specific connection mode of the first temperature measuring element 510 in the simulated cigarette is not limited, and the first temperature measuring element can be set according to the actual product requirement without departing from the concept of the present application. In some specific embodiments, the first temperature sensing element 510 may be secured in the corresponding mounting groove 111 or axial groove 710 by glue (including, but not limited to, high temperature glue, etc.). It can be appreciated that, by adopting the manner of fixing by using adhesive, the position of the first temperature measuring element 510 is difficult to be moved during the assembly process, and is relatively stable. In other embodiments, the first temperature sensing element 510 may be secured in the corresponding mounting slot 111 or axial slot 710 by a snap-fit. It will be appreciated that since the mounting groove 111 or the axial groove 710 is formed on the outer sidewall of the analog segment 100 and the inner sidewall of the circumferential bracket 700, respectively, it can be visually determined whether the first temperature measuring element 510 is mounted in place. In other embodiments, the first temperature measuring element 510 may be further secured in the corresponding mounting groove 111 or axial groove 710 by a snap fit and adhesive fit.

Example two
The difference from the first embodiment is that in the embodiment of the present application, the embodiment of the present application will be described by taking a simulated cigarette for a heating non-burning aerosol supply device (THP) of a circumferential heating system as an example. It can be understood that for the circumferential heating type heating non-combustion aerosol supply device (THP) device, there is no heating needle for heating the atomized material segment (corresponding to the simulated segment of the simulated cigarette) which needs to be inserted into the cigarette, so that the temperature measuring element can be installed at the central axis position of the atomized material segment (corresponding to the simulated segment of the simulated cigarette). Based on this, as further shown in fig. 7 and 8, in the embodiment of the present application, the mounting structure 110 'is provided on the analog segment 100', and the mounting structure 110 'is formed to extend from one end to the other end in the axial direction of the analog segment 100'. The first temperature sensing element 510 can extend from the mounting structure 110' into and reach a designated sensing location. In some particular embodiments, the mounting structure 110 'includes a mounting slot (not shown) and an axial bore 112'. A mounting groove (not shown) is located in the peripheral wall of the analog segment 100' and extends in the axial direction, and the first detection position 610 is located in the mounting groove (not shown). The axial bore 112' is located inside the analog segment 100' and extends axially, and the second detection position 620 is located in the axial bore 112'. It will be appreciated that the axial bore 112 'is closer to the central axis of the analog segment 100' relative to the mounting slot (not shown). Each of the first detection position 610 and the second detection position 620 is provided with a first temperature measuring element 510. In a preferred embodiment of the present application, ribs (not shown) are further disposed on the inner wall surface of the circumferential support 700', the ribs (not shown) protrude toward the analog section 100' on the inner wall surface of the circumferential support 700', and the ribs (not shown) are inserted into the mounting grooves (not shown) to assist in fixing the first temperature measuring element 510. Preferably, the ribs (not shown) are provided with grooves (not shown), and the grooves (not shown) cooperate with the mounting grooves (not shown) to form a containing space for containing the first temperature measuring element 510 and define the first temperature measuring element 510 in the containing space. The specific implementation of the mounting groove and the rib may refer to the related content in the first embodiment, which is not described in detail herein.
In other specific embodiments, and with further reference to FIG. 8, the mounting structure 110 'includes an axial bore 112'. The axial bore 112' is located inside the analog segment 100' and extends axially, and the second detection position 620 is located in the axial bore 112'. An axial groove 710' is provided on the inner wall surface of the circumferential support 700', and the first detection position 610 is located in the axial groove 710'. It will be appreciated that the axial bore 112' is closer to the central axis of the analog segment 100' than the axial slot 710'. Each of the first detection position 610 and the second detection position 620 is provided with a first temperature measuring element 510.
It will be appreciated that, in order to achieve the spatial lattice distribution of the first detection positions 610 and the second detection positions 620 at the analog segment 100', referring to fig. 9, the first detection positions 610 and the second detection positions 620 in the embodiment of the present application each include a plurality of first detection positions 610 and second detection positions 620 that are spaced apart along the axial direction of the analog segment 100 in the axial slot 710, and a plurality of second detection positions 620 that are spaced apart along the axial direction of the analog segment 100 in the mounting slot 111. With further reference to FIG. 9, as an exemplary and non-limiting illustration, assuming that the first detecting locations 610 include A1, B1, C1 and the second detecting locations 620 include A2, B2, C2, it will be appreciated that a first temperature measuring element 510 is disposed at each of the first detecting locations 610 and the second detecting locations 620. The heating depth and the heating efficiency of the aerosol provision device for the simulation segment 100 at a fixed height can be evaluated by radial temperature gradients (A1, A2), (B1, B2), (C1, C2) and time variations, and the heating uniformity of the aerosol provision device for the simulation segment 100 in the axial direction and the influence of the air passage on the temperature of the simulation segment 100 can be evaluated by axial temperature gradients (A1, B1, C1), (A2, B2, C2) and time variations.
Further preferably, the axial grooves 710' provided on the inner wall surface of the circumferential bracket 700' include a plurality of axial grooves 710' arranged at intervals along the circumferential direction of the circumferential bracket 700' on the inner wall surface of the circumferential bracket 700 '. It should be noted that, in the embodiment of the present application, the number of the first detection position 610, the second detection position 620, the axial hole 112 'and the axial slot 710' are not limited, and may be set according to the actual product requirement without departing from the concept of the present application.
It should be noted that the center support 800' in the embodiment of the present application is also different from the center support in the first embodiment. Referring further to fig. 7 and 8, in the embodiment of the present application, the center support 800' still has an upstream section 810', a downstream section 820', and an upstream end 830' disposed along the axial direction thereof, the upstream section 810' and the downstream section 820' being disposed in sequence along the direction of the air flow inside the simulated cigarette, the upstream end 830' being located at the end of the upstream section 810' remote from the downstream section 820 '. Unlike the first embodiment, the upstream segment 810' is located in the cooling segment 200' and the simulation segment 100' of the simulated cigarette, the downstream segment 820' is located in the filter segment 300' of the simulated cigarette, and the upstream end 830' is supported on the axial end face of the bottom cover 900 '. Specifically, the upstream end 830' is supported on an axial end surface of the second structural member 920' of the bottom cover 900 '. The outer wall of the upstream section 810' at the cooling section 200' is provided with a second side slot 811' extending along the axial direction, the second temperature measuring element 520 is fixed in the second side slot 811', the outer wall of the upstream section 810' at the simulation section 100' is provided with a third side slot 812' extending along the axial direction, the first temperature measuring element 510 is fixed in the third side slot 812', the outer wall of the downstream section 820' is provided with a first side slot 821' extending along the axial direction, and the third temperature measuring element 530 is fixed in the first side slot 821 '.
