DETAILED DESCRIPTION

[0030] The application will be described in further detail below with specific reference to the drawings. Like elements in different embodiments are denoted by like reference numerals. In the following description, numerous specific details are described to provide a thorough understanding of the application. However, those of skill in the art will recognize that the application can be practiced without these specific details. In other instances, well-known structures have not been described in detail to avoid unnecessarily obscuring the application. In addition, the description is intended to cover all alternatives, modifications and equivalents of the application.

[0031] In addition, the features, operations or steps of the description can be combined in any suitable manner in various embodiments, and the steps involved in the various embodiments can be sequentially adjusted or modified in a manner that is obvious to those skilled in the art. Therefore, the description and drawings are only intended to clearly describe one embodiment, and do not mean that the composition and / or order is necessary.

[0032] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in this application include direct and indirect connection (coupling) unless otherwise specified.

[0033] The heat-not-burn device in this application includes a relatively independent heating part and a power supply part (not shown in the figure). The power supply part can generally provide the power required for the operation of the heating part, and control and adjust the working state of the heating part. The heating part is generally matched with the aerosol generating article A to perform heating operation to form an aerosol. Of course, the heat-not-burn device can also be applied to the field of atomization, aromatherapy, etc.

[0034] It should be noted that the term "aerosol" in the specification refers to a dispersion of solid or liquid particles in a gas. "Aerosol" used herein can generally be used to refer to a substance that has been vaporized, atomized, in the form of a spray or jet, or otherwise converted from a solid or liquid form to an inhalable form containing suspended solid or liquid drug particles.

[0035] As the user demand increases, the types of aerosol generating articles A are more and more diversified, and different types of aerosol generating articles A can have different lengths. Accordingly, the structural design of the heating portion of the heat-not-burn device should be adapted to the length of the corresponding aerosol generating article A. For example, two commonly used types of TEREA (a product under the IQOS brand of Philip Morris International, with multiple flavors, and a special aerosol generating article A for the ILUMA device) and NSCs (Nature Smoke Cigarettes, a special aerosol generating article A for an oxygen-free heating and combustion device) have typical characteristics. The length of TEREA is significantly greater than that of NSCs. A single heat-not-burn device cannot be compatible with two types or even more types of aerosol generating articles A.

[0036] The present application creatively adjusts the structure of the heating portion, so that the heat-not-burn device can be compatible with two or even more types of aerosol generating articles A, reducing the user's cost investment in purchasing the device and improving the user's experience.

[0037] The heat-not-burn device comprises a housing assembly 1, a movable member 2, a driving member 3, and a locking assembly 4. The movable member 2, the driving member 3, and the locking assembly 4 form part of the structure of the heating portion of the heat-not-burn device. The housing assembly 1 can be understood as a collection of related components that form the overall outer contour structure of the heat-not-burn device, providing a containing space and a protection space for the heating portion and the power supply portion, facilitating the overall movement of the heat-not-burn device.

[0038] Please refer to Figures 1 to 9The shell assembly 1 is provided with a mounting cavity 11 and a heating cavity 12, the heating cavity 12 is used for accommodating and heating the aerosol generating article A, the shell assembly 1 is provided with a mounting hole 13 communicating with the mounting cavity 11, one end of the movable piece 2 is arranged in the mounting cavity 11, the other end of the movable piece 2 is arranged in the heating cavity 12 and can abut against the end of the aerosol generating article A, one end of the driving piece 3 is arranged in the mounting cavity 11 through the mounting hole 13 and is connected with the movable piece 2; the driving piece 3 has an unlocking state and a locking state, in the unlocking state, the driving piece 3 can move relative to the shell assembly 1 and drive the movable piece 2 to move linearly along the axis direction of the driving piece 3 to adjust the depth of the movable piece 2 extending into the heating cavity 12; in the locking state, the driving piece 3 is fixed relative to the shell assembly 1, the locking assembly 4 is used for switching the driving piece 3 between the unlocking state and the locking state, the locking assembly 4 includes a limiting piece 41 and a locking piece 42, one of the limiting piece 41 and the locking piece 42 is arranged on the driving piece 3, and the other is arranged on the shell assembly 1, in the locking state, the locking piece 42 is connected with the limiting piece 41, and the position of the driving piece 3 is fixed through the cooperation of the limiting piece 41 and the locking piece 42, in the unlocking state, the locking piece 42 is separated from the limiting piece 41, and the movement of the driving piece 3 is not limited, that is, the driving piece 3 can move relative to the shell assembly 1.

[0039] Further, the mounting cavity 11 and the heating cavity 12 in the shell assembly 1 should be two cavities that can communicate with each other, one end of the movable piece 2 is arranged in the heating cavity 12 to limit the insertion depth of the aerosol generating article A, and the other end is arranged in the mounting cavity 11 and connected with the driving piece 3, so that the mounting cavity 11 and the heating cavity 12 are arranged separately, and the aerosol generating article A is also limited in the heating cavity 12.

[0040] Due to the cooperation of the movable piece 2 and the driving piece 3, the movable piece 2 can move in the heating cavity 12, so as to change the depth of the movable piece 2 extending into the heating cavity 12, due to the abutment of the movable piece 2 with the end of the aerosol generating article A, the movable piece 2 can support the aerosol generating article A and limit the insertion depth of the aerosol generating article A, so that the substrate section of the aerosol generating article A can correspond to the heating position in the heating cavity 12, so as to fully utilize the heat generated by the heating position to heat the aerosol generating article A, and be compatible with aerosol generating articles A of different lengths. Due to the arrangement of the locking assembly 4, the unlocking and locking of the driving piece 3 can be realized, so that the driving piece 3 cannot move freely relative to the shell assembly 1 in the locking state, so as to maintain the length of the adjusted heating cavity 12, avoid the movement of the driving piece 3 and the movable piece 2 during the user's smoking process, so as to avoid the influence of the movement of the movable piece 2 on the heating of the aerosol generating article A, avoid the trouble and confusion to the user, and ensure the user's smoking taste.

[0041] In some embodiments, the driving member 3 is movably connected to the movable member 2 near one end of the heating cavity 12, and the driving member 3 can rotate around its own axis relative to the shell assembly 1. In some specific embodiments, the driving member 3 is provided with a threaded structure 341, and the movable member 2 is movably connected to the threaded structure 341 and coaxially arranged with the driving member 3. By using the mechanical principle of screw sliding, the linear motion of the movable member 2 along the axis of the driving member 3 is driven by the rotating motion of the driving member 3. The change of the rotating direction of the driving member 3 can change the motion direction of the movable member 2, so as to realize the flexible adjustment of the length of the movable member 2 extending into the heating cavity 12, so as to meet the needs of different customers or the needs of the same customer at different times. Of course, in other specific embodiments, a structure with a spiral track can be arranged between the driving member 3 and the movable member 2, and the driving member 3 can rotate along the spiral track, thereby driving the linear motion of the movable member 2 along the axis of the driving member 3.

[0042] In the present embodiment, the driving member 3 and the movable member 2 are coaxially arranged, so that the movable member 2 can be easily driven to move.

[0043] Of course, in other embodiments, the driving member 3 can move linearly along the direction perpendicular to its axis, and the linear motion of the movable member 2 along the axis direction is realized by the cooperation of the inclined surfaces between the driving member 3 and the movable member 2.

[0044] In some embodiments, the locking member 42 includes a free part 421 and a fixed part 422, and the free part 421 is movably connected to the fixed part 422. The free part 421 can rotate around a preset axis to connect or separate the free part 421 from the limiting member 41. When the free part 421 rotates relative to the fixed part 422 to separate the free part 421 from the limiting member 41, the driving member 3 can be released to move so as to facilitate the adjustment of the position of the movable member 2 in the heating cavity 12. The preset axis includes but is not limited to the axis of the fixed part 422. For example, when the fixed part 422 is a rotating shaft, the preset axis is the axis of the fixed part 422. When the fixed part 422 is a bracket 5 with a cavity in the middle, one end of the free part 421 is clamped in the cavity and can rotate relative to the bracket 5. At this time, the preset axis is the line connecting the two contact points of the free part 421 and the bracket 5 or the center line of the two contact surfaces.

[0045] Please refer to Figure 3In some specific embodiments, the limiting member 41 is arranged on the housing assembly 1, the fixed part 422 is arranged on the driving member 3, and the free part 421 can rotate around the axis of the fixed part 422 (the fixed part 422 is the rotation shaft). In the unlocked state, the free part 421 is separated from the limiting member 41, and in the locked state, the two ends of the free part 421 are connected with the limiting member 41 and the fixed part 422 respectively. Further, the fixed part 422 is arranged in the middle of the end surface of the driving member 3 away from the movable member 2, and after the free part 421 is separated from the limiting member 41, it can serve as a force structure for driving the driving member 3 to rotate. The fixed part 422 is arranged in the middle of the end surface of the driving member 3, so that the force acting on the entire end surface of the driving member 3 is uniform, avoiding the uneven force causing the movement deviating from the preset track, so that the operator can more easily and conveniently operate the movement of the driving member 3. Of course, in other embodiments, the positions of the limiting member 41 and the fixed part 422 can be exchanged, and an additional force structure needs to be arranged on the driving member 3 for the operator to operate.

[0046] In some other embodiments, the locking member 42 includes a free part 421 and a fixed part 422, the free part 421 is movably connected with the fixed part 422, and the free part 421 can move linearly relative to the fixed part 422 in a direction perpendicular to the axis of the driving member 3 to realize the connection or separation between the free part 421 and the limiting member 41.

[0047] Please refer to Figure 5 and Figure 6 In some embodiments, the limiting member 41 includes a clamping groove 411 arranged on the housing assembly 1, and in the locked state, the free part 421 is clamped in the clamping groove 411 to realize the movement limitation of the free part 421. In a specific embodiment, the clamping groove 411 is provided with at least two, and the at least two clamping grooves 411 are arranged at intervals along the circumference of the mounting hole 13, for example, the clamping groove 411 can be provided with two, three, four, etc., and the number of clamping grooves 411 can be set according to the number of compatible aerosol generating articles A. Each clamping groove 411 corresponds to one kind of aerosol generating article A. Since the fixed part 422 is arranged on the driving member 3, the free part 421 is movably connected with the fixed part 422, and the free part 421 rotates synchronously with the driving member 3, so that when the driving member 3 drives the movable member 2 to move to different positions of the heating cavity 12, there is a corresponding clamping groove 411 that can be connected with the free part 421 to fix the movable member 2 at the moving position. Through the arrangement of the clamping groove 411, the free part 421 can be arranged flush with the end surface of the housing assembly 1 in the locked state, so that the corresponding end surface of the housing assembly 1 is flat, improving the aesthetics of the heating non-combustion device.

[0048] In some specific embodiments, the movable component 2 has a first position and a second position. The first position corresponds to the installation of shorter NSCs, and the second position corresponds to the installation of longer TEREAs. For corresponding details, please refer to [link to relevant documentation]. Figure 5 and Figure 6 The number of slots 411 is two, and the included angle between the two slots 411 is set according to the rotation angle of the driving member 3 when switching between the first position and the second position. For example, the included angle between the two slots 411 is 90°. When the driving member 3 is rotated clockwise and then rotated 270°, the movable member 2 moves along the direction closer to the driving member 3 under the drive of the driving member 3, so that the movable member 2 moves from the first position to the second position, such as from... Figure 6 Rotate to the position shown in the direction of rotation. Figure 5 As shown, rotating the drive component 3 counterclockwise by 270° causes the movable component 2 to move away from the drive component 3 under its influence, moving the movable component 2 from the second position to the first position, as shown in the diagram. Figure 5 Rotate to the position shown in the direction of rotation. Figure 6 As shown. Of course, the rotation angle of the card slot 411, the drive member 3, and the moving position of the movable member 2 in this application are not limited to the above limitations.

[0049] In other embodiments, the limiting member 41 includes a limiting protrusion provided on the housing assembly 1, and the free part 421 may be provided with a groove adapted to the structure. When switched to the locking state, the groove is engaged on the limiting protrusion, which can also fix the free part 421.

[0050] In some embodiments, the free portion 421 is magnetically connected to the slot 411. One of the slot 411 and the free portion 421 has a magnetic structure, while the other is made of a magnetic material. This prevents the free portion 421 from detaching from the limiting member 41, thus avoiding affecting the performance of the heating-non-combustible device. Alternatively, both the slot 411 and the free portion 421 may have magnetic structures, or an adhesive structure such as Velcro may be used for connection.

[0051] Please see Figure 7 The drive component 3 has a first mounting groove 31 in the middle of the end face away from the movable component 2. The fixed part 422 is a rotating shaft set in the first mounting groove 31. The free part 421 is movably sleeved on the rotating shaft. The matching arrangement of the first mounting groove 31 and the slot 411 can make the end faces of the drive component 3 and the mounting housing on the same side flat. Based on the usage habits of the heating non-combustible device, the mounting hole 13 is set at the bottom of the housing assembly 1. The aerosol generating product A is inserted into the heating chamber 12 from the top. The flat arrangement of the bottom of the drive component 3 and the housing assembly 1 can also facilitate the stable placement of the heating non-combustible device.

[0052] In some specific embodiments, the first mounting groove 31 comprises at least a first groove wall 311 and a second groove wall 312 arranged in parallel, both of which extend along the axis direction of the driving member 3 and are parallel to the axis of the rotating shaft (i.e. the fixed part 422), the first groove wall 311 has a length smaller than that of the second groove wall 312, and the different lengths of the first groove wall 311 and the second groove wall 312 can limit the maximum rotation angle of the free part 421, so that the free part 421 can rotate by 90° at most, in the unlocked state, the free part 421 extends along the axis direction of the driving member 3 and at least partially abuts against the second groove wall 312, so that in the unlocked state, the free part 421 can extend along the axis direction of the driving member 3, i.e. the whole free part 421 is arranged in the middle of the driving member 3, so that the rotation contact area is increased, and the driving member 3 can be rotated more easily and with less effort, which facilitates the manual rotation of the driving member 3 by the operator.

[0053] In some embodiments, the first groove wall 311 extends to the end surface of the driving member 3 away from the movable member 2 and is flush with the end surface of the driving member 3 in the direction perpendicular to the axis of the driving member 3, so that the first groove wall 311 cannot limit the rotation of the movable member 2. Of course, the second mounting groove 32 can also be arranged on the end surface of the driving member 3 away from the movable member 2, one end of the second mounting groove 32 extends to the edge of the driving member 3, and the other end extends to the first groove wall 311, so that the second mounting groove 32 communicates with the first mounting groove 31, in the locked state, the free part 421 extends from the first mounting groove 31 to the limiting part 41 through the second mounting groove 32. When the limiting part 41 is a clamping groove 411, the second mounting groove 32 can communicate with the clamping groove 411 along with the rotation of the driving member 3, the first groove wall 311 extends to the second mounting groove 32, so that the free part 421 can be rotated to the final state of being clamped in the clamping groove 411 and the second mounting groove 32, or being separated from the second mounting groove 32 and the clamping groove 411 and abutting against the second groove wall 312.

The inner end cover 15 and the outer end cover 16 clamp the structure of the driving member 3, which is simple and convenient to realize and assemble.

[0055] In some embodiments, the driving member 3 comprises a driving portion 33 and a transmission portion 34 arranged in sequence, a threaded structure 341 is arranged on at least part of the structure of the transmission portion 34, the threaded structure 341 extends along the axial direction of the driving member 3, and the movable member 2 is movably connected with the threaded structure 341; the outer side of the driving portion 33 is provided with a flange 331, the flange 331 extends outwardly along a direction perpendicular to the axis of the driving member 3, the flange 331 is arranged in the mounting space 17, and the two sides of the flange 331 are respectively in abutment with the clamping protrusion 151 and the outer end cover 16.

[0056] It should be noted that the above-mentioned inner and outer are two opposite directions, the direction towards the center of the mounting hole 13 is inward, and the direction away from the center of the mounting hole 13 is outward.

[0057] Based on the fact that the temperature at the heating cavity 12 is relatively high when heating is not combusted in the present application, the movable member 2 is movably arranged in the heating cavity 12, therefore, the movable member 2 should have good high-temperature resistance, for example, being made of PEEK material with high-temperature resistance.
