The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0045] See also Figures 1 to 13An embodiment of the present application provides an aerosol generating device, which includes an aerosol medium component 100 and a host 200. The atomizing medium assembly 100 includes a storage disk 40, a storage disk 30, a strip medium 20 and a shell 10 having a heating area 10a. The storage disk 40 and the storage disk 30 are both arranged in the shell 10. The storage disk 30 is used to wind the strip medium 20. The strip medium 20 can be unwound from the storage disk 30 and wound on the storage disk 40 after passing through the heating area 10a. The strip medium 20 can be heated and generate an aerosol in the heating area 10a; the host 200 includes a driving shaft 240 driven and connected to the storage disk 40, and the driving shaft 240 is configured to drive at least part of the rotation of the storage disk 40; wherein, the storage disk 40 includes an installation channel 41a, and in the process of the driving shaft 240 extending into the installation channel 41a, part of the structure of the storage disk 40 can undergo elastic deformation. When the driving shaft 240 is assembled in place, the storage disk 40 restores the elastic deformation and is limitedly matched with the driving shaft 240 along its circumference.

[0046] The specific structure of the housing 10 is not limited, and it can be used to accommodate the strip medium 20. For example, see Figures 6 to 9 The housing 10 includes a first housing 11 and a second housing 12, which are arranged opposite to each other and define a heating area 10a. The strip medium 20 can be arranged in the area between the first housing 11 and the second housing 12. The first housing 11 and the second housing 12 can be detachably connected, so that the strip medium 20 can be replaced with a new strip medium 20 after use, and the housing 10 can be reused, thereby reducing the user's use cost.

[0047] The strip medium 20 is a flexible strip structure with a certain width and thickness, but the length can be extended and bent according to actual conditions.

[0048] The surface of the strip medium 20 is coated with, or the interior is infiltrated with, or embedded with, an aerosol generating substrate for generating aerosol. The aerosol generating substrate includes, but is not limited to, medicines or materials containing nicotine, and the like.

[0049] For example, the strip-shaped medium 20 may include a base tape and an aerosol generating substrate alternately and intermittently coated on the base tape.

[0050] The base tape may be any tape that can withstand heating temperature, has certain flexibility, and can be unwound and rewound, such as a paper tape, a polymer tape, a metal base tape, a graphite base tape, etc. The base tape may also be a metal mesh, which may be formed by weaving metal wires or by providing a plurality of through holes on a metal sheet.

[0051] Among them, unwinding refers to the process of peeling off the outer layer of the substrate and the inner layer of the substrate in the radial direction of the rolled substrate. Winding refers to the method of winding a continuous product with a reel, a reel, etc.

[0052] Part of the strip medium 20 can move into the heating area 10a and be heated to generate aerosol. In other words, the strip medium 20 can continuously pass through the heating area 10a, and the aerosol generating substrate on the part of the strip medium 20 currently in the heating area 10a can generate aerosol. It is understood that when the entire strip medium 20 passes through the heating area 10a, it means that the strip medium 20 has been used up.

[0053] The shell 10 can store and accommodate the strip medium 20, that is, the unused strip medium 20 is stored in the shell 10. During the use of the atomized medium assembly 100, the unused strip medium 20 passes through the heating area 10a in sequence and is heated for use, and the used strip medium 20 is still accommodated in the shell 10.

[0054] When the user inhales the aerosol, the drive shaft 240 rotates to drive the storage tray 40 to rotate. Through the rotation of the storage tray 40, the used strip medium 20 can be wound on the storage tray 40. At the same time, the storage tray 30 follows the storage tray 40, so that the strip medium 20 stored on the storage tray 30 is unwound.

[0055] It should be noted that if Fig.10 and Fig.11 As shown, in some embodiments, the storage tray 40 can be an integrated structure, so that the drive shaft 240 drives the storage tray 40 to rotate as a whole. In other embodiments, the storage tray 40 can also be a split structure, for example, the storage tray 40 includes a first part and a second part that are connected along its axial direction, one of the first part and the second part is connected to the drive shaft 240 to wind the strip medium 20, and the other does not rotate.

[0056] By providing the storage disk 30 , the storage disk 30 can be rotated, which is conducive to unwinding the strip medium 20 from the storage disk 30 , and reducing the friction between the strip medium 20 and the housing 10 during the unwinding process.

[0057] By providing the storage tray 40 , the storage tray 40 can be rotated to facilitate winding the strip medium 20 onto the storage tray 40 , thereby reducing the friction between the strip medium 20 and the housing 10 during the winding process.

[0058] The specific manner in which the strip medium 20 generates aerosol in the heating area 10a is not limited. Figure 4The host 200 includes a heating component 220, and the strip medium 20 in the heating area 10a generates aerosol under the influence of the heating component 220. The heating method of the heating component 220 includes but is not limited to resistance heating, electromagnetic heating, infrared heating, microwave heating, laser heating, etc. Of course, atomization can also be performed by ultrasound or other methods, which are not specifically limited here.

[0059] In the process of the drive shaft 240 extending into the installation channel 41a, part of the structure of the storage tray 40 can undergo elastic deformation. That is to say, in the process of the drive shaft 240 extending into the installation channel 41a, part of the structure of the storage tray 40 may undergo elastic deformation. For example, in the process of the drive shaft 240 extending into the installation channel 41a in a non-parallel state with the axial direction of the installation channel 41a, the drive shaft 240 may squeeze the storage tray 40, and the storage tray 40 undergoes elastic deformation under the action of the squeezing force, so that the drive shaft 240 can continue to extend into the interior of the installation channel 41a. Of course, in the process of the drive shaft 240 extending into the installation channel 41a in a parallel state with the axial direction of the installation channel 41a, the drive shaft 240 may not squeeze the storage tray 40, the storage tray 40 is not subject to squeezing force, and will not undergo elastic deformation, and the drive shaft 240 can also be assembled in place.

[0060] It should be noted that, when the drive shaft 240 is assembled in place, the axial direction of the drive shaft 240 is parallel to the axial direction of the installation channel 41 a .

[0061] The state in which the drive shaft 240 is assembled in place refers to the state in which at least one side of the drive shaft 240 forms a limited fit with the storage tray 40 along the circumference of the storage tray 40, that is, the rotation of the drive shaft 240 can drive the storage tray 40 to rotate.

[0062] In the related art, the storage tray is a rigid structure as a whole. In the process of installing the atomizing medium assembly, it is necessary to keep the axial direction of the installation channel parallel to the axial direction of the driving shaft, and the storage tray and the driving shaft can achieve a limited fit angle along the circumference of the storage tray, so as to achieve the installation of the atomizing medium assembly. In the process of the driving shaft extending into the installation channel, if the axial direction of the installation channel is not parallel to the axial direction of the driving shaft, or the installation angle of the storage tray along its circumference does not meet the angle that can achieve limited fit with the driving shaft, interference will occur between the driving shaft and the storage tray, so that the driving shaft cannot be assembled in place, which makes the installation of the atomizing medium assembly inconvenient.

[0063] In the aerosol generating device of the embodiment of the present application, part of the structure of the storage tray 40 can be elastically deformed. When the drive shaft 240 extends into the installation channel 41a, after the drive shaft 240 is squeezed into the storage tray 40, the squeezed part of the storage tray 40 can be elastically deformed under the action of the squeezing force, so that the drive shaft 240 continues to move in the direction of extending into the installation channel 41a. After the drive shaft 240 is assembled in place, the part of the structure of the storage tray 40 that has been elastically deformed can also restore the elastic deformation, so that the drive shaft 240 can be conveniently limited along its circumference with the storage tray 40. The rotation of the drive shaft 240 can drive the storage tray 40 to rotate. In other words, the aerosol generating device of the embodiment of the present application expands the installation angle range between the installation channel 41a and the drive shaft 240, so that it is convenient to install the atomized medium assembly 100 on the host 200, thereby improving the assembly efficiency of the aerosol generating device.

[0064] See also Figure 4 , Figures 7 to 9 In one embodiment, the housing 10 further comprises an air outlet channel 111a, one end of which is connected to the heating region 10a, and the other end of which is connected to the outside. The aerosol generated in the heating region 10a can flow out through the air outlet channel 111a, so as to be used by the user. The aerosol generating device further comprises a suction piece 300, which is connected to the housing 10 and connected to the other end of the air outlet channel 111a. The user can inhale the aerosol generated in the heating region 10a through the suction piece 300.

[0065] The shell 10 also has an air inlet channel 112b (specifically, the air inlet channel 112b may be provided on the first shell 11), and the external air flow enters the shell 10 through the air inlet channel 112b and flows to the heating area 10a, thereby being able to carry the aerosol generated in the heating area 10a and flow out through the air outlet channel 111a.

[0066] The atomized medium assembly 100 is detachably disposed in the main unit 200. Figures 1 to 4 The host 200 includes a main shell 210 and an outer cover 230. The main shell 210 is formed with an installation area 210a. The heating component 220 and the driving shaft 240 are both arranged in the installation area 210a. The atomizing medium component 100 is detachably arranged in the installation area 210a, and the open side of the installation area 210a is closed by the outer cover 230. During the suction process, the external airflow can enter the installation area 210a through the gap between the main shell 210 and the outer cover 230, and then enter the interior of the housing 10 through the air inlet channel 112b, thereby realizing the air intake of the aerosol generating device. The main shell 210 and the outer cover 230 can be connected by magnetic connection, clamping, threaded connection, plug-in or ultrasonic connection, for example.

[0067] After the strip medium 20 is used, the outer cover 230 can be removed from the main shell 210 to replace a new atomized medium assembly 100. Of course, when the strip medium 20 and the shell 10 are in a detachable structure, the atomized medium assembly 100 can be taken out from the installation area 210a, and then the shell 10 is opened, and the atomized medium assembly 100 is replaced with a new strip medium 20, and then the atomized medium assembly 100 is installed in the installation area 210a.

[0068] The host 200 further includes a power supply assembly, which is disposed in the main housing 210, and the heating assembly 220 is electrically connected to the power supply assembly for heating the strip medium 20. The power supply assembly is non-detachably connected to the main housing 210 until the power supply assembly is exhausted and can be discarded. Alternatively, the power supply assembly is detachably connected to the main housing 210, that is, the power supply assembly can be detachable and replaceable, or rechargeable (inside or outside the aerosol generating device).

[0069] The method of forming the air outlet channel 111a in the housing 10 is not limited. Figure 4 , Figures 6 to 9 The first shell 11 of the housing 10 includes a shell body 112 and a protruding column 111 . The shell body 112 and the second shell 12 define a heating area 10 a . The strip medium 20 is disposed in an area between the shell body 112 and the second shell 12 .

[0070] Specifically, in this embodiment, the air inlet passage 112 b may be disposed on the shell body 112 .

[0071] The shape of the protrusion 111 is not limited. For example, it can be cylindrical, square, etc. For example, see Figures 6 to 9 The boss 111 is cylindrical, and the suction piece 300 can be connected to the boss 111 at any angle along the circumferential direction, thereby facilitating user operation and improving user experience.

[0072] The air outlet channel 111a is roughly formed on the top side of the shell 10. The aerosol generated in the heating area 10a can be directly discharged through the convex column 111. The convex column 111 is closer to the user. The aerosol can be transported from the air outlet channel 111a to the outside in a shorter time and used by the user.

[0073] The protruding column 111 can facilitate the connection of the suction member 300 to the housing 10, thereby achieving the suction of aerosol.

[0074] There is no limitation on the connection method between the suction member 300 and the boss 111. For example, the connection can be achieved by a detachable connection method such as plug-in connection or snap-in connection.

[0075] like Figure 4 , Figures 7 to 9As shown, in some embodiments, the atomized medium assembly 100 includes a sealing ring 60, which is sandwiched between the boss 111 and the suction piece 300. The material of the sealing ring 60 is not limited. For example, it can be silicone. By arranging the sealing ring 60 between the suction piece 300 and the boss 111, the sealing performance between the suction piece 300 and the boss 111 is better, reducing the possibility of aerosol overflowing through the connection gap between the two, and also reducing the possibility of external airflow entering the suction piece 300 from the connection gap between the two, so that the user can stably inhale the aerosol through the suction piece 300.

[0076] Please refer to 3 to Figure 8 In one embodiment, the housing 10 further comprises a storage space 10b and a receiving space 10c. The storage space 10b is separated from the receiving space 10c. The receiving tray 40 is disposed in the receiving space 10c, and the storage tray 30 is disposed in the storage space 10b.

[0077] Specifically, see Figure 7 and Figure 8 A storage space 10b and a receiving space 10c are defined between the shell body 112 and the second shell 12.

[0078] The storage space 10b is separated from the storage space 10c. That is, by placing the unused strip medium 20 and the used strip medium 20 in two separate spaces, the unused strip medium 20 and the used strip medium 20 are isolated from each other, which can improve the odor mixing between the unused strip medium 20 and the used strip medium 20 to a certain extent. In addition, it can also prevent the debris generated by the used strip medium 20 from sticking to the unused strip medium 20, thereby preventing the generation of burnt odor to a certain extent.

[0079] In the related art, the aerosol generating matrix strip will deform, harden, and produce burr and stratification phenomena after being atomized by the heating component. However, the aerosol generating device in the related art does not have a structure specifically used to store the aerosol generating matrix strip after use, which may further cause the aerosol generating matrix strip after use to generate debris.

[0080] The atomized medium assembly 100 provided in this embodiment can reduce the generation of debris to a certain extent by providing a storage space 10c specifically for storing the used strip medium 20 in the housing 10, and can reduce the debris from entering the storage space 10b and sticking to the unused strip medium 20 by separating the storage space 10b from the storage space 10c. In addition, the used strip medium 20 is rolled up by the storage tray 40, and the used strip medium 20 is rolled into a roll, which can further reduce the generation of debris. At the same time, by providing a storage space 10b specifically for storing the unused strip medium 20 in the housing 10, the unused strip medium 20 can be protected, so that the user experience is better.

[0081] See also Fig. 9 In one embodiment, a drive connection hole 112a is provided on the shell body 10 (specifically, a drive connection hole 112a is provided on the shell body 112), and the drive connection hole 112a is located on one axial side of the mounting channel 41a. The drive shaft 240 can pass through the drive connection hole 112a and extend into the mounting channel 41a, so that the drive shaft 240 and the storage tray 40 can be driven and connected.

[0082] See also Figure 2 , Figure 4 , Figure 5 , Figures 10 to 12 In one embodiment, the storage tray 40 includes an elastic member 42 and a tray body 41 having a mounting channel 41a. The elastic member 42 is disposed on a side wall of the mounting channel 41a, and the drive shaft 240 can be limitedly matched with the elastic member 42 along its circumference.

[0083] When the axial direction of the drive shaft 240 is not parallel to the axial direction of the installation channel 41a, the end of the drive shaft 240 will squeeze the elastic member 42 during the process of the drive shaft 240 extending into the installation channel 41a. The elastic member 42 will elastically deform under the action of the squeezing force and open along the radial direction of the installation channel 41a, thereby avoiding the drive shaft 240.

[0084] In this embodiment, the elastic member 42 is the portion of the storage tray 40 that can undergo elastic deformation. While facilitating the drive shaft 240 to extend into the installation channel 41a, the elastic member 42 can also achieve limited cooperation with the drive shaft 240 along the circumference of the drive shaft 240, thereby facilitating the drive shaft 240 to drive the storage tray 40 to rotate.

[0085] See also Figures 10 to 12In one embodiment, the elastic member 42 includes a connecting arm 421 arranged on the side wall of the mounting channel 41a and an elastic arm 422 connected to the connecting arm 421, the elastic arm 422 extends along the side wall of the mounting channel 41a, and is spaced from the side wall of the mounting channel 41a to form an avoidance gap 40a; in the process of the drive shaft 240 extending into the mounting channel 41a, the elastic arm 422 can be driven to undergo elastic deformation along the radial direction of the mounting channel 41a, and when the drive shaft 240 is assembled in place, the elastic arm 422 restores the elastic deformation and cooperates with the drive shaft 240 in a limiting manner along the circumferential direction of the drive shaft 240.

[0086] The connection arm 421 is provided to facilitate installation of the elastic arm 422 on the installation channel 41 a , and at the same time, an avoidance gap 40 a is formed between the elastic arm 422 and the side wall of the installation channel 41 a .

[0087] The avoidance gap 40 a can provide elastic deformation space for the elastic arm 422 .

[0088] As the drive shaft 240 gradually extends into the installation channel 41a, the angle between the axial direction of the drive shaft 240 and the axial direction of the installation channel 41a becomes smaller and smaller until the two are in a parallel state. The elastic arm 422 can restore at least part of the elastic deformation and fit against the side wall of the drive shaft 240.

[0089] It should be noted that after the axial direction of the drive shaft 240 is parallel to the axial direction of the installation channel 41a, when the drive shaft 240 is not yet in the assembled state, the elastic arm 422 does not completely restore the elastic deformation. The drive shaft 240 can be rotated by a certain angle, and the elastic arm 422 continues to restore the elastic deformation during this process, so that the elastic arm 422 and the drive shaft 240 are limitedly matched along the circumference of the drive shaft 240.

[0090] See also Figures 6 to 8 , Figures 10 to 12 In one embodiment, a partial area of ​​the side wall of the driving shaft 240 is recessed to form a first limiting groove 240a, and the elastic member 42 can be inserted into the first limiting groove 240a and limitedly cooperate with the first limiting groove 240a along the circumference of the installation channel 41a.

[0091] Specifically, see Figure 5 The elastic arm 422 can be inserted into the first limiting groove 240a to achieve limiting cooperation with the driving shaft 240 along the circumferential direction.

[0092] After the drive shaft 240 extends into the installation channel 41a, and the axial direction of the drive shaft 240 is parallel to the axial direction of the installation channel 41a, if the elastic arm 422 fits the non-depressed area of ​​the drive shaft 240, at this time, the elastic arm 422 is still in an elastic deformation state. The drive shaft 240 rotates, and after the elastic arm 422 is rotated to the outside of the first limiting groove 240a, the elastic arm 422 continues to restore the elastic deformation, so that it can be stuck in the first limiting groove 240a. Under the limiting action of the first limiting groove 240a, the drive shaft 240 continues to rotate, so that a certain torsional force can be transmitted to the elastic arm 422, and the elastic arm 422 transmits this torsional force to the disk body 41 through the connecting arm 421, thereby driving the disk body 41 to rotate to wind the strip medium 20.

[0093] The limiting cooperation between the storage tray 40 and the drive shaft 240 is achieved by the matching structure between the first limiting groove 240a and the elastic member 42. This matching structure is relatively simple and does not require special alignment to install the atomizing medium assembly 100. In this way, the installation angle range of the storage tray 40 installed on the drive shaft 240 along its circumference is also expanded, thereby facilitating the user to replace the atomizing medium assembly 100.

[0094] See also Figures 10 to 12 In one embodiment, there are multiple elastic members 42 , and the elastic members 42 are evenly spaced and distributed along the circumference of the installation channel 41 a . The number of the first limiting grooves 240 a corresponds to the number of the elastic members 42 .

[0095] It should be noted that, in the embodiments of the present application, a plurality refers to any number of two or more than two.

[0096] Illustratively, in the embodiment of the present application, the number of the elastic member 42 and the number of the first limiting groove 240a are both two.

[0097] By providing a plurality of elastic members 42 to correspond to the plurality of first limiting grooves 240 a , the reliability of the circumferential limiting cooperation between the driving shaft 240 and the storage tray 40 is improved.

[0098] See also Figures 10 to 12 In one embodiment, a first guide surface 240b is provided at the end of the driving shaft 240, and along a first direction, the first guide surface 240b gradually approaches the axis of the driving shaft 240, wherein the first direction is the direction in which the driving shaft 240 extends into the mounting channel 41a when the axial direction of the driving shaft 240 is parallel to the axial direction of the mounting channel 41a.

[0099] Exemplarily, the first direction is as follows Fig.11 and Fig.12 The direction shown by d1.

[0100] It should be noted that the first direction is a vector direction.

[0101] By setting the first guide surface 240b, when the drive shaft 240 extends into the installation channel 41a, the storage tray 40 cooperates with the first guide surface 240b (specifically, the first guide surface 240b cooperates with the elastic arm 422), thereby facilitating the movement of the drive shaft 240 in the direction of extending into the installation channel 41a.

[0102] In addition, when the drive shaft 240 extends into the installation channel 41a, the drive shaft 240 can apply a squeezing force to the storage tray 40 through the first guide surface 240b. It can be understood that the transmission of the force through the surface reduces the pressure of the squeezing force on the storage tray 40, thus reducing the probability of the drive shaft 240 damaging the storage tray 40.

[0103] See also Figures 10 to 12 In one embodiment, a second guide surface 422a is provided at the end of the elastic member 42, and along the first direction, the second guide surface 422a gradually approaches the axis of the mounting channel 41a, wherein the first direction is the direction in which the drive shaft 240 extends into the mounting channel 41a when the axial direction of the drive shaft 240 is parallel to the axial direction of the mounting channel 41a.

[0104] Specifically, a second guide surface 422 a is provided at one end of the elastic arm 422 of the elastic member 42 away from the connecting arm 421 .

[0105] Exemplarily, the first direction is as follows Fig.11 and Fig.12 The direction shown by d1.

[0106] It should be noted that the first direction is a vector direction.

[0107] By setting the second guide surface 422a, when the drive shaft 240 extends into the installation channel 41a, the second guide surface 422a cooperates with the drive shaft 240 (specifically, it can cooperate with the first guide surface 240b of the drive shaft 240). When the drive shaft 240 extends into the installation channel 41a, the drive shaft 240 can first touch the second guide surface 422a. The direction of the extrusion force applied by the drive shaft 240 to the elastic arm 422 is perpendicular to the second guide surface 422a, and the second guide surface 422a is inclined relative to the first direction. In this way, the extrusion force has a component force along the radial direction of the installation channel 41a, so that the drive shaft 240 drives the elastic arm 422 to open along the radial direction of the installation channel 41a, and then facilitates the drive shaft 240 to continue to move in the direction of extending into the installation channel 41a.

[0108] See also Figures 3 to 5 , Fig.10 and Fig.11 In one embodiment, along the circumferential direction of the installation channel 41a, the elastic member 42 is limitedly matched with the side wall of the installation channel 41a.

[0109] It is understandable that the maximum radial dimension of the installation channel 41a is larger than the maximum radial dimension of the drive shaft 240. When the drive shaft 240 is assembled in place and it rotates and drives the storage tray 40 to rotate, the elastic member 42 may undergo circumferential elastic deformation due to the circumferential torsional force.

[0110] In this embodiment, the elastic member 42 is limited in the circumferential direction by the side wall of the installation channel 41a, and the elastic member 42 basically does not undergo elastic deformation in the circumferential direction of the installation channel 41a. In this way, the structural stability of the elastic member 42 in the circumferential direction of the installation channel 41a is improved, making it easier for the drive shaft 240 to drive the disk body 41 to rotate through the elastic member 42.

[0111] See also Figures 3 to 5 , Fig.10 , Fig.11 and Fig.13 In one embodiment, the atomizing medium assembly 100 further includes a fixing member 50, at least a portion of which is disposed in the mounting channel 41a, and along the circumference of the mounting channel 41a, the fixing member 50 is respectively limitedly matched with the elastic member 42 and the side wall of the mounting channel 41a.

[0112] In this embodiment, the elastic member 42 and the side wall of the installation channel 41 a are circumferentially limited by the fixing member 50 .

[0113] That is to say, based on the storage tray 40, the elastic arms 422 of the elastic member 42 will not form a direct contact relationship with the side walls of the installation channel 41a along the circumferential sides of the installation channel 41a, so that the elastic member 42 is easy to demold.

[0114] See also Figure 5 , Fig.10 , Fig.11 and Fig.13 In one embodiment, the fixing member 50 is provided with a first limiting surface 50a and a second limiting surface 50b along its circumference, and the elastic member 42 is sandwiched between the first limiting surface 50a and the second limiting surface 50b.

[0115] The formation method of the first limiting surface 50a and the second limiting surface 50b is not limited. Fig.13 As shown, a notch is formed on the fixing member 50, and the side walls of the notch along both sides of the circumference of the fixing member 50 are respectively a first limiting surface 50a and a second limiting surface 50b.

[0116] The first limiting surface 50 a and the second limiting surface 50 b can limit the elastic member 42 on both sides of the installation channel 41 a in the circumferential direction, respectively. In this way, the fixing member 50 can achieve limiting cooperation with the elastic member 42 in the circumferential direction.

[0117] See also Figure 5 , Fig.10 , Fig.11 and Fig.13 In one embodiment, one of the outer side wall of the fixing member 50 and the side wall of the mounting channel 41a is provided with a second limiting groove 52a, and the other is provided with a limiting protrusion 41b, at least a portion of the limiting protrusion 41b extends into the second limiting groove 52a and cooperates with the second limiting groove 52a along the circumferential limiting direction of the mounting channel 41a.

[0118] Specifically, the outer wall of the fixing member 50 may be provided with a second limiting groove 52a, and the side wall of the installation channel 41a may be provided with a limiting protrusion 41b; or the outer wall of the fixing member 50 may be provided with a limiting protrusion 41b, and the side wall of the installation channel 41a may be provided with a second limiting groove 52a.

[0119] The limiting protrusion 41b and the second limiting groove 52a realize the clamping limiting, so that the fixing member 50 realizes limiting cooperation with the side wall of the installation channel 41a along its circumference.

[0120] The structure of the clamping and limiting of the limiting protrusion 41b and the second limiting groove 52a is relatively simple. Thus, the structures of the storage tray 40 and the fixing member 50 are also relatively simple, which is convenient for production.

[0121] See also Figure 5 , Figures 10 to 13 In one embodiment, the mounting channel 41a passes through the storage tray 40, the driving shaft 240 extends into the mounting channel 41a through one axial end of the mounting channel 41a, and the fixing member 50 is disposed in the mounting channel 41a through the other axial end of the mounting channel 41a.

[0122] It can be understood that a limiting protrusion 41b and an elastic member 42 are provided on the side wall of the installation channel 41a.

[0123] By setting the installation channel 41a to pass through both ends of the storage tray 40 along its axial direction, the storage tray 40 can be ejected from the mold along both ends of the axial direction of the installation channel 41a during the injection molding process, thereby injection molding the elastic member 42 and the limiting protrusion 41b. In other words, the storage tray 40 of this embodiment reduces the difficulty of ejecting the storage tray 40, thereby facilitating the production of the storage tray 40.

[0124] In addition, since the driving shaft 240 needs to extend into the mounting channel 41 a from one end of the mounting channel 41 a and the other axial end of the mounting channel 41 a is also open, the installation of the fixing member 50 is facilitated.

[0125] The specific structure of the fixing member 50 is not limited. Figure 5 , Figures 10 to 13In one embodiment, the fixing member 50 includes a top cover 51 and a side panel 52 arranged around the outer periphery of the top cover 51. Along the circumference of the mounting channel 41a, the side panel 52 is respectively limited by the elastic member 42 and the side wall of the mounting channel 41a, and the top cover 51 seals the other end of the mounting channel 41a.

[0126] like Fig.13 As shown, in this embodiment, the side panel 52 is provided with a first limiting surface 50a, a second limiting surface 50b and a second limiting groove 52a.

[0127] The top cover 51 can effectively close at least a portion of one axial end of the mounting channel 41a, thereby reducing the possibility of foreign debris and other impurities entering the interior of the shell 10 through the mounting channel 41a, that is, reducing the probability of parts inside the shell 10 malfunctioning due to interference from foreign debris (for example, debris causing the strip medium 20 to be unable to move, etc.), thereby improving the reliability of the aerosol generating device.

[0128] In addition, when the airtightness inside the housing 10 is required to be high, the top cover 51 can close at least a portion of one axial end of the installation channel 41 a , thereby enhancing the sealing performance inside the housing 10 .

[0129] See also Figure 5 , Figures 10 to 13 In one embodiment, the fixing member 50 is provided with a receiving groove 50c, and at least a portion of the driving shaft 240 is located in the receiving groove 50c.

[0130] Specifically, Fig.13 As shown, the top cover 51 and the side panels 52 are arranged to form a receiving groove 50c.

[0131] It is understandable that at least a portion of the drive shaft 240 extending into the installation channel 41a can be accommodated by the accommodation groove 50c. In other words, along the radial direction of the installation channel 41a, there is an overlapping portion between the drive shaft 240 and the fixing member 50.

[0132] By providing the receiving groove 50c, the dimension of the fixing member 50 extending into the installation channel 41a can be longer, and will not interfere with the driving shaft 240. In this way, along the axial direction of the installation channel 41a, the dimension of the fixing member 50 for the position-limiting matching portion with the elastic member 42 and the side wall of the installation channel 41a is larger, thereby improving the reliability of the position-limiting matching structure between the fixing member 50 and the elastic member 42 and the side wall of the installation channel 41a.
