Therefore, the various sequences in the specification and drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0037] 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.

[0038] Please refer to Figures 1 to 8 The embodiment of the present application provides a heating non-combustion device, which comprises a shell assembly 10, a containing assembly 20, a locking assembly 30, a first elastic member 40, a heating assembly, a control assembly and other functional components as needed, which will be described below.

[0039] Please refer to Figures 1 to 6 The shell assembly 10 can be understood as a collection of related components that constitute the overall profile of the device. The heating non-combustion device can be held, moved, carried, and operated by the shell assembly 10. The interior of the shell assembly 10 forms a containing cavity 10a for accommodating the containing assembly 20. The containing cavity 10a can be shaped to match the profile of the containing assembly 20, for example, the containing cavity 10a is a cylindrical cavity space with a predetermined length. The containing cavity 10a is in communication with the outside of the shell assembly 10, which can also be understood as the shell wall of the shell assembly 10 being provided with an opening communicating with the containing cavity 10a, so that the containing assembly 20 can be at least partially inserted into the containing cavity 10a in a pluggable manner.

[0040] Exemplarily, please refer to Figures 2 to 6 and Figure 8 The shell assembly 10 comprises an outer shell 11, an inner shell 12, a containing sleeve 13 and an end cover 14; wherein the outer shell 11 is sleeved on the periphery of the inner shell 12, the containing sleeve 13 is located at one end of the outer shell 11 and fixed between the outer shell 11 and the inner shell 12, and the sleeve space of the containing sleeve 13 is the containing cavity 10a; the end cover 14 is fixedly arranged at the other end of the outer shell 11 to cooperate with the outer shell 11 and the inner shell 12 to form the internal space of the shell assembly 10; the other internal space of the shell assembly 10 except the containing cavity 10a can provide support for the structural assembly and layout of the functional components such as the heating assembly, the locking assembly 30 and the control assembly. Of course, the shell assembly 10 can also adopt other suitable structures, which will not be described here.

[0041] For the convenience of distinguishing and describing, the axial direction and the radial direction are defined based on the structure of the accommodation cavity 10a, the disassembly mode of the accommodation assembly 20, the overall structure of the heating non-combustion device, and the like. The axial direction can be understood as the direction of the central axis of the accommodation cavity 10a, for example, the direction of the central axis of the accommodation cavity 10a shown in Figure 3 and Figure 4 is the up-down direction, and the up-down direction is the axial direction. The radial direction can be understood as the direction perpendicular to the central axis of the accommodation cavity 10a, for example, the left-right direction in the accommodation cavity 10a shown in Figure 3 and Figure 4 is the radial direction.

[0042] Please refer to Figures 1 to 6 , the accommodation assembly 20 is inserted into the accommodation cavity 10a in a pluggable manner along the axial direction, mainly used for accommodating and placing aerosol generating articles to cooperate with the heating assembly to heat the aerosol generating articles; for example, the aerosol generating articles can be partially inserted into the accommodation assembly 20 to achieve the output of aerosol by directly sucking the aerosol generating articles; for another example, the aerosol generating articles are completely accommodated in the accommodation assembly 20, and the accommodation assembly 20 is used as a mouthpiece structure of the heating non-combustion device to achieve the output of aerosol.

[0043] Using the accommodation assembly 20 as a carrier member for placing the aerosol generating articles in the heating non-combustion device can avoid the direct structural connection relationship between the aerosol generating articles and the device main body part (i.e., other functional members except the accommodation assembly 20), which can not only provide support for easily and quickly disassembling the aerosol generating articles, but also avoid the residues generated in the process of plugging and unplugging the aerosol articles from being retained in the interior of the device main body.

[0044] The accommodation assembly 20 is provided with a first locking structure 20a on one side in the radial direction (for example, on the radial side wall), and the first locking structure 20a is mainly used for cooperating with the locking assembly 30 to achieve the position locking and releasing of the accommodation assembly 20 (or together with the aerosol generating articles accommodated therein). Specifically, by cooperating the first locking structure 20a with the locking assembly 30, on the one hand, the accommodation assembly 20 can be stably locked in the accommodation cavity 10a or the shell assembly 10 to provide support for the normal use (such as heating the aerosol generating articles) of the heating non-combustion device; on the other hand, by releasing the accommodation assembly 20, the accommodation assembly 20 can be moved out of the accommodation cavity 10 or separated from the shell assembly 10, thereby facilitating the disassembly of the aerosol generating articles.

[0045] Exemplarily, please refer to Figures 2 to 6The accommodation assembly 20 comprises a sleeve member 21 and a cup member 22. The cup member 22 is substantially a single-end open cup structure, and the aerosol generating article can be inserted into the cup member 22 in a pluggable manner, so as to be accommodated and placed in the cup member 22. The sleeve member 21 is fixedly sleeved on the periphery of the cup member 22, for example, the sleeve member 21 is fixedly sleeved on the cup member 22 in an interference fit. The first locking structure 20a is arranged on the radial side wall of the sleeve member 21.

[0046] In some embodiments, the sleeve member 21 can be made of a heat insulation material, which can not only reduce the heat generated during the heating of the aerosol generating article from being transferred to the shell assembly 10, thereby reducing heat loss and improving heat utilization, but also provide structural protection for the cup member 22 from the periphery of the cup member 22.

[0047] In some embodiments, the sleeve member 21 can be omitted, or the sleeve member 21 and the cup member 22 can be integrated into a one-piece structure. As long as the accommodation assembly 20 can accommodate and place the aerosol generating article, and the first locking structure 20a is arranged on one side of the accommodation assembly 20 in the radial direction, the above-mentioned embodiments can be implemented. Details are not described herein.

[0048] Please refer to Figures 3 to 7 The locking assembly 30 is arranged on the shell assembly 10, for example, the locking assembly 30 is arranged inside the shell assembly 10, or part of the locking assembly 30 is arranged outside the shell assembly 10. The locking assembly 30 has a second locking structure 30a, which is arranged to be controllably moved radially towards and away from the first locking structure 20a, so as to cooperate with the first locking structure 20a to lock and release the accommodation assembly 20.

[0049] Specifically, when the second locking structure 30a is moved radially towards and connected to the first locking structure 20a, for example, the second locking structure 30a is in a connected relationship of alignment, insertion, clamping, abutting, adsorption, etc. with the first locking structure 20a, the accommodation assembly 20 is stably limited and fixed in the accommodation cavity 10a, so as to realize the position locking of the accommodation assembly 20 (or together with the aerosol generating article). When the second locking structure 30a is moved radially and separated from the first locking structure 20a, the accommodation assembly 20 is released or unlocked.

[0050] Exemplarily, please refer to Figures 3 to 7The locking assembly 30 is arranged inside the housing assembly 10, and includes a driving member 31 and a locking member 32. The driving member 31 is a power member capable of outputting linear motion, for example, the driving member 31 can include a linear motor, a pneumatic cylinder or other power element, or the driving member 31 can also be a linear power device formed by combining a motor and associated moving components. The body of the driving member 31 is fixedly connected to the housing assembly 10 (specifically, the inner housing 12) and electrically connected to the control assembly. The power end of the driving member 31 is coupled to the locking member 32, and the second locking structure 30a is arranged at the end of the locking member 32 away from the driving member 31 in the radial direction (for example, the second locking structure 30a or the locking member 32 can be arranged through the peripheral wall of the accommodating sleeve 13 in the radial direction).

[0051] Therefore, by controlling the driving member 31 to open and close, adjusting the motion output state of the driving member 31, etc., the locking member 32 can be driven by the driving member 31 to move the second locking structure 30a along the radial direction to approach and move away from the first locking structure 20a, so as to lock the accommodating assembly 20 when the second locking structure 30a approaches and connects the first locking structure 20a, and release the accommodating assembly 20 when the second locking structure 30a moves away from and separates from the first locking structure 20a, thereby realizing automatic control of locking and releasing the accommodating assembly 20.

[0052] In some embodiments, other ways can also be used to drive the second locking structure 30a to move in the radial direction; for example, the driving member 31 and / or the locking member 32 are mechanical structural members slidably mounted on the housing assembly 10, and at least part of the driving member 31 is arranged outside the housing assembly 10. By manually pushing and pulling the driving member 31 in the radial direction, the locking member 32 can drive the second locking structure 30a to move in the radial direction, thereby realizing manual control of locking and releasing the accommodating assembly 20.

[0053] Please refer to Figures 3 to 6 The first elastic member 40 is arranged between the housing assembly 10 and the accommodating assembly 20 in the axial direction. The first elastic member 40 can include a spring, an elastic column, an elastic flap or other structural members capable of elastically deforming in the axial direction, and is mainly used to provide an elastic force to make the accommodating assembly 20 have a tendency to move out of the accommodating cavity 10a in the axial direction. For the convenience of distinguishing and describing, the two ends of the first elastic member 40 in the axial direction are defined as the first end and the second end of the first elastic member 40, respectively.

[0054] Exemplarily, please refer to Figures 3 to 6The sleeve member 21 has a tube side wall enclosing the cup member 22, and the tube side wall is provided with an accommodation cavity 20b extending in the axial direction. The tube side wall is provided with an opening communicating with the accommodation cavity 20b on the end face of the cup opening end of the cup member 22 in the axial direction. Alternatively, the tube side wall of the sleeve member 21 is a double-wall structure with an inner peripheral tube wall and an outer peripheral tube wall spaced apart. The inner peripheral tube wall and the outer peripheral tube wall are connected at one end in the axial direction and are spaced apart in the radial direction at the other end in the axial direction, thereby forming an accommodation cavity 20b with one end closed and the other end open. The cup member 22 is fixed to the inner peripheral tube wall by interference fit.

[0055] The first elastic member 40 can be a spring structure. The first elastic member 40 is partially inserted into the accommodation cavity 20b in the form of surrounding the cup member 22. The first end of the first elastic member 40 is fixedly connected to the sleeve member 21 in the accommodation cavity 20b. The second end of the first elastic member 40 extends out of the accommodation cavity 20b through the opening. That is, when the first elastic member 40 is in an unstressed state, the second end of the first elastic member 40 extends out and is exposed to the outside of the accommodation assembly 20 in the axial direction.

[0056] On the one hand, the first elastic member 40 can be inserted into the accommodation cavity 10a together with the accommodation assembly 20, and the second end of the first elastic member 40 abuts against the housing assembly 10 in the accommodation cavity 10a. In the state that the first locking structure 20a and the second locking structure 30a are connected, the first elastic member 40 is compressed and deformed by the axial extrusion of the accommodation assembly 20 and the housing assembly 10, and stores elastic potential energy. When the first locking structure 20a and the second locking structure 30a are separated, the elastic potential energy stored in the first elastic member 40 is released, so that the accommodation assembly 20 can be ejected a distance in the axial direction to the outside of the accommodation cavity 10a, thereby providing support for conveniently and quickly disassembling and replacing the aerosol generating article.

[0057] For example, after one end of the accommodation assembly 20 (for example, the part where the cup opening end of the cup member 22 is located) is ejected a distance out of the accommodation cavity 10a, the user can easily and labor-savingly pull out the accommodation assembly 20 together with the aerosol generating article and the first elastic member 20 from the accommodation cavity 10a or the housing assembly 10, then separate from the body of the heating non-combustion device, and then pull out the aerosol generating article from the accommodation assembly 20. In this way, the disassembly and replacement of the aerosol generating article can be easily and quickly achieved, and the residue caused by the breakage of the aerosol generating article can be avoided to stay inside the housing assembly 10.

[0058] On the other hand, by partially accommodating the first elastic member 40 in the accommodation cavity 20b and fixedly connecting the first elastic member 40 with the accommodation assembly 20, the influence of the first elastic member 40 on the accommodation assembly 20 or the overall appearance of the heat-not-burn device can be reduced, the integrity of the profile of the accommodation assembly 20 or the heat-not-burn device can be ensured, and the balance of the force on the accommodation assembly 20 during the insertion and removal of the accommodation assembly 20 can be ensured, so that the accommodation assembly 20 can be smoothly inserted into the accommodation cavity 10a or smoothly removed from the accommodation cavity 10a.

[0059] In other embodiments, the first elastic member 40 can also adopt other suitable installation forms.

[0060] For example, the first elastic member 40 is arranged in the accommodation cavity 10a, the second end of the first elastic member 40 is fixed with the shell assembly 10, and the first end of the first elastic member 40 abuts the accommodation assembly 20 in the axial direction; when the accommodation assembly 20 is inserted into the accommodation cavity 10a, the first elastic member 40 can be pressed in the axial direction, so that the first elastic member 40 is deformed by contraction under pressure and stores elastic potential energy; on the contrary, when the first elastic member 40 releases the elastic potential energy, the accommodation assembly 20 can be driven to move a distance towards the opening end of the accommodation cavity 10a.

[0061] For another example, the first elastic member 40 can be at least partially exposed to the shell assembly 10, such as being fixed around the accommodation sleeve 13 to the outer shell 11; during the process of inserting the accommodation assembly 20 into the accommodation cavity 10a, the first elastic member 40 is gradually compressed; on the contrary, when the locking assembly 30 releases the accommodation assembly 20, the accommodation assembly 20 can be at least partially ejected out of the accommodation cavity 10a by the elastic force provided by the first elastic member 40.

[0062] For another example, the first end of the first elastic member 40 can be fixed to the cup member 22 (for example, the bottom end of the cup member 22), or be sleeved around the outer sleeve 21 and the first end be fixed with the outer sleeve 21; in this way, the second end of the first elastic member 40 can also abut the shell assembly 10, thereby providing support for the accommodation assembly 20 to be ejected a distance out of the accommodation cavity 10a.

[0063] For another example, the first end of the first elastic member 40 can be fixed to the cup member 22 (for example, the bottom end of the cup member 22), or be sleeved around the outer sleeve 21 and the first end be fixed with the outer sleeve 21; in this way, the second end of the first elastic member 40 can also abut the shell assembly 10, thereby providing support for the accommodation assembly 20 to be ejected a distance out of the accommodation cavity 10a. Figures 3 to 6 The heating assembly is arranged inside the shell assembly 10 and is mainly used for heating the aerosol generating article together with the accommodation assembly 20, thereby generating the aerosol for use. For example, the heating assembly includes a heating element 50 electrically connected to the control assembly, and the heating element 50 is substantially a needle columnar structure fixedly arranged in the accommodation cavity 10a in the axial direction. Correspondingly, the accommodation assembly 20 is provided with a plug-in hole 20c allowing the heating element 50 to be inserted into the inside of the accommodation assembly 20, for example, the plug-in hole 20c is arranged in the axial direction through the bottom end of the cup member 22.

[0064] In the process of inserting the aerosol generating article into the accommodation assembly 20, the heating element 50 can gradually penetrate into the aerosol generating article through the insertion hole 20c, so as to stably restrict the aerosol generating article in the accommodation assembly 20 by the heating element 50. Alternatively, the accommodation assembly 20 is pre-locked to the housing assembly 10, and the heating element 50 is inserted into the accommodation assembly 20; then, in the process of inserting the aerosol generating article into the accommodation assembly 20, the heating element 50 gradually penetrates into the aerosol generating article to finally restrict and fix the aerosol generating article in the accommodation assembly 20.

[0065] In the state that the locking assembly 30 locks the accommodation assembly 20, the aerosol generating substrate can be fully heated in a central heating mode by the direct contact relationship between the heating element 50 and the aerosol generating substrate, and the usable aerosol is generated.

[0066] In the process of removing the aerosol generating article, the aerosol generating article can be quickly separated from the heating element 50 due to the elastic force of the first elastic member 40 for quickly ejecting the accommodation assembly 20, and the aerosol generating substrate is not easy to adhere to the heating element 50, so as to effectively reduce or avoid the generation of residues, thereby providing support for easily and conveniently pulling out the aerosol generating article from the accommodation assembly 20 or cleaning out the exhausted aerosol generating article from the accommodation assembly 20.

[0067] In some embodiments, the heating assembly 20 can also adopt other suitable structures; for example, the accommodation assembly 20 omits the cup member 22, and the heating element 50 is in a tubular structure; in the state that the sleeve member 21 is inserted into the accommodation cavity 10a and is locked, the heating element 50 extends into the sleeve member 21 or is in communication with the sleeve member 21; then, in the process of inserting the aerosol generating article into the sleeve member 21 and partially extending into the heating element 50, the aerosol generating article can be heated in a circumferential heating mode by the heating element 50. All of the above will not be repeated here.

[0068] Please refer to Figure 3 , Figure 5 and Figure 8 The control assembly can be understood as a collection of related devices in the heat-not-burn device that can regulate and manage the functions of the heating assembly, the locking assembly 30 and other functional components, and the control assembly can provide support for realizing part or all of the functions of the heat-not-burn device.

[0069] Exemplarily, please refer to Figure 3 , Figure 5 and Figure 8The control assembly includes a control board 61, a power supply cell 62, and an operation key 63. The control board 61 is arranged inside the shell assembly 10 (e.g., fixed to the inner shell 12), and the heating assembly (e.g., the heating element 50), the locking assembly 30 (e.g., the driving element 31), and the power supply cell 62 are electrically connected to the control board 61. The operation key 63 is connected to the control board 61 and exposed outside the shell assembly 10 (e.g., exposed outside the end cover 14). For example, the operation key 63 is a switch component capable of outputting an electrical signal, and the operation key 63 is electrically connected to the control board 61. For another example, the operation key 63 is a structural component arranged in the shell assembly 10, and the control board 61 is provided with a switch component capable of being triggered by the operation key 63 at a position corresponding to the operation key 63.

[0070] In this way, the operation key 63 can input a preset instruction to the heat-not-burn device to trigger the control board 61 to control the heating assembly and the locking assembly 30.

[0071] For example, when the accommodation assembly 20 is inserted into the accommodation cavity 10a to a preset position, the control board 61 can be triggered by pressing the operation key 63 to control the driving element 31 to start, so that the locking element 32 drives the second locking structure 30a to move close to the first locking structure 20a to a position where the two are connected, thereby locking the accommodation assembly 20. After the aerosol generating article is inserted into the accommodation assembly 20, the operation key 63 can be pressed to control the heating assembly to start heating.

[0072] For example, when it is necessary to disassemble and replace the aerosol generating article, the second locking structure 30a can be controlled to move away from the first locking structure 20a by pressing the operation key 63, so as to release the accommodation assembly 20, thereby finally performing the disassembly operation on the aerosol generating article.

[0073] In some embodiments, the locking assembly 30 can also be automatically locked or released to the accommodation assembly 20 based on the detection of the state information of the aerosol generating article or the state information of the heat-not-burn device, and the heating assembly can be automatically started or stopped. The operation key 63 can be used to forcibly unlock the accommodation assembly 20 or stop the heating assembly.

[0074] It should be noted that the control mode of the heating assembly and the locking assembly 30 by the operation key 63 can be selected as needed, for example, based on the time difference between short pressing and long pressing or the number of pressing times, so that the control board 61 can control the heating assembly and the locking assembly 30 to execute different working modes (e.g., to control the locking assembly 30 to execute forced unlocking). That is, the control logic of the control assembly or the heat-not-burn device can refer to the prior art, and the control logic or control principle of the heat-not-burn device is not improved in the present application.

[0075] Based on this, by using the second locking structure 30a which can move along the radial direction to approach and move away from the first locking structure 20a, the locking and releasing of the accommodation assembly 20 can be achieved by the cooperation of the first locking structure 20a and the second locking structure 30a.

[0076] When the first locking structure 20a is connected with the second locking structure 30a (see Figure 5 ), in the state of locking the accommodation assembly 20, the aerosol generating article can be stably limited in the accommodation assembly 20 by the heating assembly (for example, the heating element 50), and then the aerosol for use can be generated by heating the aerosol generating article.

[0077] When the first locking structure 20a is separated from the second locking structure 30a (see Figure 6 ), in order to release the accommodation assembly 20 together with the aerosol generating article, the at least part of the accommodation assembly 20 can be easily and quickly ejected from the accommodating cavity 10a (see Figure 4 ) by the elastic force provided by the first elastic member 40; in this way, the aerosol generating article can be conveniently, quickly, easily and labor-savingly taken out or pulled out from the accommodation assembly 20, and the residue can be reduced or avoided, so that the residue cannot easily stay in the internal part of the device main body or the accommodation assembly 20, thereby effectively improving the use experience of the heat-not-burn device.

[0078] It should be noted that those skilled in the art should know that the common aerosol generating article can be an aerosol generating substrate only having a stable or fixed profile (for example, a columnar shape), or a structure (for example, a columnar structure) formed by packaging the aerosol generating substrate into a package (for example, a polyamide ester material, a special paper material for cigarettes, etc.).

[0079] Exemplarily, a typical aerosol generating article can be divided into a substrate section, a cooling section and a filter section along the length direction thereof; wherein the substrate section is formed by packaging the medicinal material, the flavoring material, the tobacco and the like aerosol generating substrate into a package. By heating the substrate section at a high temperature, the aerosol generating substrate or the aerosol generating article can generate the aerosol for use without combustion.

[0080] It can be understood that the description of the aerosol generating article herein is only for more clearly and thoroughly understanding the structure, implementation principle and the like of the heat-not-burn device, and the aerosol generating article itself does not constitute a limitation on the heat-not-burn device.

[0081] In some embodiments, please refer to Figures 3 to 7The locking assembly 30 comprises a driving member 31, a locking member 32 and a second elastic member 33. The second elastic member 33 is connected between the locking member 32 and the driving end of the driving member 31 in the radial direction. The second elastic member 33 can comprise a spring, an elastic column, an elastic flap or other elastic structural member capable of elastic extension and contraction deformation in the radial direction, and is mainly used to provide an elastic force for the second locking structure 30a (or the locking member 32) to have a moving trend in the radial direction towards the first locking structure 20a.

[0082] Exemplarily, the second locking structure 30a is connected in a plug-in sleeve fitting manner with the first locking structure 20a. Please refer to Figures 3 to 7 The first locking structure 20a comprises a locking insertion hole arranged on the side wall of the accommodating assembly 20 in the radial direction (specifically, the peripheral wall of the sleeve member 10). Correspondingly, the second locking structure 30a comprises a locking protrusion arranged on the end face of the locking member 32 in the radial direction, for example, the locking protrusion and the locking member 32 are in an integrated structure.

[0083] Please refer to Figure 3 and Figure 4 The driving member 31 drives the locking member 32 to move leftward, so that the locking protrusion stays in the accommodating cavity 10a. During the process that the accommodating assembly 20 is inserted into the accommodating cavity 10a in the axial direction, the locking member 32 can move rightward due to the rightward pressing action of the side wall of the accommodating assembly 20 on the locking protrusion, so that the second elastic member 33 is pressed to contract and deform and stores elastic potential energy.

[0084] Please refer to Figure 5 When the accommodating assembly 20 moves downward to the position where the locking insertion hole and the locking protrusion are opposite in the radial direction, the accommodating assembly 20 releases the pressing action on the locking protrusion, the second elastic member 33 releases the elastic potential energy and drives the locking member 32 to move the locking protrusion leftward, so that the locking protrusion is inserted into the locking insertion hole, thereby limiting and fixing the accommodating assembly 20 in the accommodating cavity 10a (at this time, the first elastic member 40 is pressed to contract).

[0085] Please refer to Figure 6 When it is needed to take out the aerosol generating article, the driving member 31 drives the locking member 32 to move leftward together with the locking protrusion and the second elastic member 33, so that the locking protrusion moves out of the locking insertion hole, thereby releasing the accommodating assembly 20, so that the accommodating assembly 20 can at least partially pop out of the accommodating cavity 10a under the action of the first elastic member 40 (please refer to Figure 4 ); after the accommodating assembly 20 is popped out, the driving member 31 can again drive the locking member 32 and the like to move leftward, so that the locking protrusion returns to the initial position in the accommodating cavity 10a (please refer to Figure 3 ).

[0086] Therefore, the second elastic member 33 can establish a non-rigid connection relationship between the accommodation assembly 20 (specifically, the first locking structure 20a) and the locking assembly 30 (specifically, the second locking structure 30a) or the shell assembly 10, so that the accommodation assembly 20 can be stably locked and positioned, smoothly inserted and extracted, and the related components can be prevented from being damaged due to improper external force on the accommodation assembly 20.

[0087] It should be noted that, Figure 3 and Figure 4 The thick dashed line with an arrow in the figure indicates the moving direction of the accommodation assembly 20.

[0088] In some embodiments, referring to Figure 7 , the side surface of the locking protrusion in the axial direction (for example, the upper surface on the side of the cup opening end of the cup member 22) is provided with a beveled structure, which can provide guidance support for the radial movement of the locking protrusion. When the accommodation assembly 20 is inserted into the accommodation cavity 10a, the beveled structure can be used to gradually press the locking protrusion to the right, thereby smoothly guiding the locking protrusion to the radial side of the accommodation assembly 20, so as to avoid the accommodation assembly 20 and the locking protrusion from being stuck during insertion and extraction due to structural interference.

[0089] As described above, the second locking structure 30a and the first locking structure 20a can also adopt a radial abutting, clamping, magnetic attraction or other connection mode.

[0090] For example, the second locking structure 30a can be an arc-shaped plate structure capable of moving radially in the accommodation cavity 10a, and the curvature of the second locking structure 30a can be set to be matched with the curvature of the outer contour of the accommodation assembly 20. In this way, the second locking structure 30a can be locked by abutting against the peripheral side of the accommodation assembly 40 through the elastic force generated by the second elastic member 33 or the power provided by the driving member 31.

[0091] For another example, the first locking structure 20a is a magnetic member arranged on the peripheral side wall of the sleeve member 21, and the second locking structure 30a is a magnetic member arranged on the locking member 32. The second locking structure 30a can be driven by the driving member 31 to move radially towards and away from the first locking structure 20a, so as to realize the magnetic attraction or separation of the first locking structure 20a and the second locking structure 30a, thereby locking or releasing the accommodation assembly 20.

[0092] In some embodiments, referring to Figures 3 to 6The driving member 31 comprises a driving motor 31a and a transmission member 31b; the driving motor 31a is fixed to the shell assembly 10 and electrically connected to a control assembly (for example, a control board 61), the transmission member 31b is screwed to a power shaft of the driving motor 31a (for example, the power shaft of the driving motor 31a is inserted into the transmission member 31b in a threaded connection manner), and the transmission member 31b is connected to the shell assembly 10 in a radial sliding manner, and the second elastic member 33 is connected between the locking member 32 and the transmission member 31b.

[0093] In this way, through the threaded connection relationship between the transmission member 31b and the driving motor 31a, the rotational motion output by the driving motor 31a can be converted into the linear motion of the locking member 32 (together with the second locking structure 30a) in the radial direction, which is conducive to the fine control of the moving position of the locking member 32 or the second locking structure 30a and improves the stability of the movement of the second locking structure 30a; and through the forward and reverse rotation control of the driving motor 31a, the second locking structure 30a is driven to move close to and away from the first locking structure 20a, so that the locking or releasing of the accommodation assembly 20 can be finally realized.

[0094] In some embodiments, referring to Figure 7 The locking member 32 is a hollow shell structure, and an installation cavity 30b is formed in the inside of the locking member 32; one end of the transmission member 31b away from the driving member 31a in the radial direction is inserted into the installation cavity 30b in a sliding manner; and the second elastic member 33 (for example, a spring) is arranged in the installation cavity 30b and connected to the transmission member 31b, for example, the second elastic member 33 and the transmission member 31b abut each other.

[0095] By accommodating and placing the second elastic member 33 in the inside of the locking member 32, a modular locking assembly 30 can be formed, so that the locking assembly 30 can be installed in the shell assembly 10 as a structural complete and relatively independent functional component, thereby creating favorable conditions for conveniently and quickly realizing the assembly forming or disassembly and maintenance of the heat-not-burn device; at the same time, the compactness and stability of the overall structure of the locking assembly 30 can be effectively improved.

[0096] The above application of specific examples is used to illustrate the present application, which is only used to help understand the present application and does not limit the present application. According to the idea of the present application, those skilled in the art can make some simple deductions, deformations or substitutions.
