During the assembly process of the main unit and the atomizing medium assembly, the heating assembly needs to extend into the atomizing medium assembly to heat the strip medium. However, in an aerosol generating device of this structure, during the assembly process of the main unit and the atomizing medium assembly, the heating assembly may squeeze the strip medium, which may lead to the risk of deformation or breakage of the strip medium. Utility Model Content

[0003] In view of this, the embodiments of the present application hope to provide an aerosol generating device, aiming to reduce the probability of problems such as deformation or breakage of the strip medium.

[0004] To achieve the above objectives, the present application provides an aerosol generating device, comprising:

[0005] A host, comprising a main shell and a heating component, wherein the main shell is provided with a mounting area extending along a first direction, two ends of the mounting area along the first direction are respectively a first end and a second end, and the heating component is provided in the mounting area and close to the first end along the first direction;

[0006] An atomized medium assembly comprises a strip medium and a shell having a heating area, a portion of the strip medium is arranged in the heating area, and two ends of the shell along the first direction are respectively an assembly end and a mating end;

[0007] In which, a first matching portion is provided on the main shell, and a second matching portion is provided on the shell. When the matching end abuts against the first end and the assembly end rotates around the matching end in the direction of entering the installation area, the first matching portion and the second matching portion can form interference to limit the rotation of the assembly end and make the heating component and the strip medium in a separated state; when the assembly end abuts against the second end and the matching end rotates around the assembly end in the direction of entering the installation area, the first matching portion and the second matching portion cooperate to enable the shell to be assembled in the installation area, and at least part of the heating component extends into the heating area to heat the strip medium.

[0008] In one embodiment, the first matching portion is provided on the side wall of at least one side of the installation area along the second direction, and the second matching portion is provided on the side wall of at least one side of the shell along the second direction, and the first matching portion corresponds to the second matching portion one by one; wherein the second direction intersects with the first direction.

[0009] In one embodiment, one of the first mating portion and the second mating portion is a track boss, and the other is a track groove, and when the mating end abuts against the first end and the assembly end rotates around the mating end in a direction to enter the installation area, the side wall of the track boss can interfere with the side wall of the track groove; when the assembly end abuts against the second end and the mating end rotates around the assembly end in a direction to enter the installation area, the track boss can move freely around the assembly end in the track groove.

[0010] In one embodiment, the first mating portion is the track boss, and along the first direction, the distance between the track boss and the first end is smaller than the distance between the heating component and the first end, and the spacing between the side of the track boss facing the first end and the side of the heating component facing the first end is not less than 4 mm.

[0011] In one embodiment, the first matching portion is the track boss, the extension direction of the heating component is a third direction, and along the third direction, the ratio of the size of the track boss to the size of the wall surface of the heating component protruding from the installation area is not less than 0.7.

[0012] In one embodiment, the side walls of the track boss on opposite sides along the first direction and the side walls of the track groove on opposite sides along the first direction are both arc-shaped. When the shell is assembled in the installation area, the side walls of the track boss on opposite sides along the first direction and the side walls of the track groove on opposite sides along the first direction are both bent toward the side away from the second end.

[0013] In one embodiment, when the housing is assembled in the installation area, the strip medium in the heating area is located on a side of the heating component facing the first end.

[0014] In one embodiment, a thickness direction of the heating component is parallel to the first direction.

[0015] In one embodiment, a thickness direction of the strip medium located in the heating area is parallel to the first direction.

[0016] In one embodiment, the shell further has a storage space and a receiving space, the storage space is separated from the receiving space, the atomized medium assembly also includes a storage disk arranged in the storage space and a receiving disk arranged in the receiving space, the storage disk is used to wind the strip medium, the strip medium can be unwound from the storage disk, and wound on the receiving disk after passing through the heating area.

[0017] In one embodiment, the host further comprises a driving shaft, and when the shell is assembled in the installation area, at least a portion of the driving shaft extends into the storage space and is drivingly connected to the storage tray.

[0018] In the aerosol generating device of the embodiment of the present application, when the mating end abuts against the first end and the assembly end rotates around the mating end in the direction of entering the installation area, the first mating portion and the second mating portion can form interference to limit the rotation of the assembly end and to place the heating component and the strip medium in a separated state. That is, after the assembly end rotates around the mating end to the interference position of the first mating portion and the second mating portion, the assembly end can no longer continue to rotate around the mating end in the direction of entering the installation area, and the strip medium and the heating component are in a separated state, and the heating component will not squeeze the strip medium. When the assembly end abuts against the second end and the mating end rotates around the assembly end in the direction of entering the installation area, the first mating portion and the second mating portion cooperate to allow the shell to be assembled in the installation area, and at least part of the heating component extends into the heating area to heat the strip medium. That is, when the mating end rotates around the assembly end, the first mating portion and the second mating portion will not interfere, so that the atomized medium component can be assembled in the installation area. Therefore, when the atomizing medium assembly is assembled in the installation area, the heating assembly can be inserted into the heating area at a smaller inclination angle and the relative displacement in the heating area is smaller, which is beneficial to reduce the probability of the heating assembly squeezing the strip medium in the heating area and causing the strip medium to deform or break.

[0039] Please also read Figures 1 to 11The embodiment of the present application provides an aerosol generating device, which includes a main unit 200 and an atomizing medium assembly 100. The main unit 200 includes a main shell 210 and a heating assembly 220. The main shell 210 is provided with an installation area 210a extending along a first direction. The two ends of the installation area 210a along the first direction are respectively a first end 210b and a second end 210c. The heating assembly 220 is arranged in the installation area 210a and close to the first end 210b along the first direction. The atomizing medium assembly 100 includes a strip medium 20 and a shell 10 having a heating area 10a. Part of the strip medium 20 is arranged in the heating area 10a. The two ends of the shell 10 along the first direction are respectively an assembly end 10m and a mating end 10n. The main shell 210 is provided with a first mating portion 210d, and the shell 10 is provided with a second mating portion 10x. At the mating end 10a, the first mating portion 210d is provided. 0n abuts against the first end 210b, and the assembly end 10m rotates around the matching end 10n in the direction of entering the installation area 210a, the first matching portion 210d and the second matching portion 10x can form interference to limit the rotation of the assembly end 10m, and make the heating component 220 and the strip medium 20 in a separated state; when the assembly end 10m abuts against the second end 210c, and the matching end 10n rotates around the assembly end 10m in the direction of entering the installation area 210a, the first matching portion 210d and the second matching portion 10x cooperate to make the housing 10 be assembled in the installation area 210a, and at least part of the heating component 220 extends into the heating area 10a to heat the strip medium 20. The host 200 of the aerosol generating device of the embodiment of the present application can be recycled, that is, the host 200 of an aerosol generating device can match multiple atomizing medium components 100, thereby reducing the user's use cost and being environmentally friendly.

[0040] The specific direction of the first direction is not limited. Figures 2 to 4 , Figure 6 , Figure 8 The direction shown by d1.

[0041] The heating component 220 is used to heat the strip medium 20 to generate aerosol. The heating method of the heating component 220 is not limited. For example, in the embodiment of the present application, the heating method can be contact heating.

[0042] It should be noted that the contact heating method refers to a heating method in which the heating component 220 and the strip medium 20 are in contact to transfer heat. The heating component 220 includes, for example, a resistor module, which converts electrical energy into thermal energy, so that it can be used to heat the strip medium 20.

[0043] The heating assembly 220 is close to the first end 210b along the first direction. That is, along the first direction, the distance between the heating assembly 220 and the first end 210b is smaller than the distance between the heating assembly 220 and the second end 210c.

[0044] 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).

[0045] See also Figure 1 and Figure 2 The main body 200 further includes an outer cover 230. The atomized medium assembly 100 is detachably disposed 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 to achieve air intake of the aerosol generating device. The main shell 210 and the outer cover 230 can be connected by magnetic connection, snap connection, threaded connection, plug connection or ultrasound, for example.

[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 Fig.10 and Fig.11 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 is disposed in the heating area 10a. That is, part of the strip medium 20 can move into the heating area 10a and be heated to generate aerosol, 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 turn and is heated for use. The used strip medium 20 is still accommodated in the shell 10 to prevent the atomized medium residue from falling into the host 200 and causing pollution.

[0054] After the strip medium 20 is used up, the outer cover 230 can be removed from the main shell 210 to replace a new atomizing medium assembly 100. Of course, when the strip medium 20 and the shell 10 are in a detachable structure, the atomizing medium assembly 100 can also be taken out from the installation area 210a, and then the shell 10 is opened, and the atomizing medium assembly 100 is replaced with a new strip medium 20, and then the atomizing medium assembly 100 is installed in the installation area 210a. The host 200 of the aerosol generating device of the embodiment of the present application can be recycled, that is, the host 200 of an aerosol generating device can match multiple atomizing medium assemblies 100, thereby reducing the user's use cost and being environmentally friendly.

[0055] That is to say, the aerosol generating device of the embodiment of the present application can replace the atomizing medium assembly 100 during use, that is, the user needs to independently operate to assemble the atomizing medium assembly 100 in the installation area 210a. Generally speaking, based on operating habits, there are the following two assembly methods to achieve the assembly of the atomizing medium assembly 100 in the installation area 210a.

[0056] The first assembly method: please refer to Figure 2 and Figure 3 , so that the mating end 10n is pressed against the first end 210b to form a position, and then the assembly end 10m is rotated around the mating end 10n in the direction of entering the installation area 210a, so that the atomized medium assembly 100 is assembled in the installation area 210a as a whole. It can be understood that since the heating assembly 220 is close to the first end 210b, when the atomized medium assembly 100 is assembled in this assembly method, the assembly end 10m only needs to rotate around the mating end 10n at a small angle, and the heating assembly 220 will be inserted into the heating area 10a, and the rotation angle of the assembly end 10m around the mating end 10n is small, and the inclination angle of the heating assembly 220 when inserted into the heating area 10a is relatively large. If the assembly end 10m continues to be rotated in this direction, the assembly end 10m needs to be rotated at a larger angle so that the atomized medium assembly 100 can be assembled as a whole in the installation area 210a. The relative displacement of the heating assembly 220 in the heating area 10a is also large, thereby squeezing the strip medium 20 in the heating area 10a and causing the strip medium 20 to deform or break.

[0057] The second assembly method: please combine Figure 2 and Figure 4 , so that the assembly end 10m is pressed against the second end 210c to form a position, and then the mating end 10n is rotated around the assembly end 10m in the direction of entering the installation area 210a, so that the atomized medium assembly 100 is assembled in the installation area 210a as a whole. It can be understood that since the heating assembly 220 is far away from the second end 210c, when the atomized medium assembly 100 is assembled in this assembly method, the mating end 10n will be rotated around the assembly end 10m at a large angle before the heating assembly 220 is inserted into the heating area 10a, and since the mating end 10n has been rotated at a large angle, the heating assembly 220 will also be inserted into the heating area 10a at a smaller inclination angle. If the mating end 10n continues to be rotated in this direction, the mating end 10n only needs to be rotated at a smaller angle so that the atomized medium assembly 100 can be assembled as a whole in the installation area 210a, and the relative displacement of the heating assembly 220 in the heating area 10a is also smaller, which is beneficial to reduce the probability of the heating assembly 220 squeezing the strip medium 20 in the heating area 10a and causing the strip medium 20 to deform or break.

[0058] That is to say, compared with the first assembly method, the second assembly method is used to assemble the atomized medium assembly 100, and the possibility of the strip medium 20 being squeezed by the heating assembly 220 is lower, which is helpful to reduce the probability of deformation or breakage of the strip medium 20.

[0059] Based on this, in the aerosol generating device of the embodiment of the present application, when the mating end 10n abuts against the first end 210b and the assembly end 10m rotates around the mating end 10n in the direction of entering the installation area 210a, the first mating portion 210d and the second mating portion 10x can form interference to limit the rotation of the assembly end 10m and to separate the heating component 220 from the strip medium 20. That is, after the assembly end 10m rotates around the mating end 10n to the interference position between the first mating portion 210d and the second mating portion 10x, the assembly end 10m can no longer continue to rotate around the mating end 10n in the direction of entering the installation area 210a, and at the same time, the strip medium 20 and the heating component 220 are in a separated state, and the heating component 220 will not squeeze the strip medium 20. When the assembly end 10m abuts against the second end 210c and the mating end 10n rotates around the assembly end 10m in the direction of entering the installation area 210a, the first mating portion 210d and the second mating portion 10x cooperate to enable the housing 10 to be assembled in the installation area 210a, and at least part of the heating component 220 extends into the heating area 10a to heat the strip medium 20. That is, when the mating end 10n rotates around the assembly end 10m, the first mating portion 210d and the second mating portion 10x will not interfere with each other, so that the atomized medium component 100 can be assembled in the installation area 210a. Therefore, when the atomized medium component 100 is assembled in the installation area 210a, the heating component 220 can be inserted into the heating area 10a at a smaller inclination angle, and the relative displacement in the heating area 10a is smaller, which is conducive to reducing the probability of the heating component 220 squeezing the strip medium 20 in the heating area 10a and causing the strip medium 20 to deform or break.

[0060] That is to say, the aerosol generating device of the embodiment of the present application can avoid the user from assembling the atomizing medium assembly 100 in the first assembly method, and can assemble the atomizing medium assembly 100 in the second assembly method, thereby reducing the probability of deformation or breakage of the strip medium 20 and other problems.

[0061] The position of the first mating portion 210d on the main housing 210 and the position of the second mating portion 10x on the housing 10 are not limited. Figures 2 to 4 , Fig.10 and Fig.11 In one embodiment, a first matching portion 210d is provided on the side wall of at least one side of the installation area 210a along the second direction, and a second matching portion 10x is provided on the side wall of at least one side of the shell 10 along the second direction, and the first matching portion 210d corresponds to the second matching portion 10x one by one; wherein the second direction intersects with the first direction.

[0062] The specific direction of the second direction is not limited. For example, the second direction is Figure 2 , Figure 3 The direction shown by d2.

[0063] The second direction may be orthogonal to the first direction.

[0064] A first matching portion 210d is provided on the side wall of at least one side of the installation area 210a along the second direction. That is, the first matching portion 210d may be provided on one side of the installation area 210a along the second direction, and the second matching portion 10x may be provided on the side of the housing 10 corresponding to the first matching portion 210d; or the first matching portion 210d may be provided on both opposite sides of the installation area 210a along the second direction, and the second matching portion 10x may be provided on both opposite sides of the housing 10 along the second direction.

[0065] The first mating portion 210d is disposed in the installation area 210a. After the atomizing medium assembly 100 and the main shell 210 are assembled, the first mating portion 210d and the second mating portion 10x can be hidden in the installation area 210a, that is, they will not protrude from the outside of the main shell 210. In this way, the impact of the first mating portion 210d and the second mating portion 10x on the installation of other parts of the aerosol generating device is reduced. For example, refer to Figure 1 and Figure 2 When the aerosol generating device further includes the aforementioned outer shell, the first matching portion 210d and the second matching portion 10x will not affect the installation between the outer shell and the main shell 210.

[0066] In addition, the first matching portions 210d are also conveniently disposed on both sides of the mounting area 210a along the second direction.

[0067] It should be noted that the types of the first matching portion 210d and the second matching portion 10x are not limited. Figures 2 to 4 , Figures 8 to 11 In one embodiment, one of the first mating portion 210d and the second mating portion 10x is a track boss, and the other is a track groove. When the mating end 10n abuts against the first end 210b and the assembly end 10m rotates around the mating end 10n to enter the installation area 210a, the side wall of the track boss can interfere with the side wall of the track groove; when the assembly end 10m abuts against the second end 210c and the mating end 10n rotates around the assembly end 10m to enter the installation area 210a, the track boss can move freely around the assembly end 10m in the track groove.

[0068] Specifically, in the embodiment of the present application, the first matching portion 210d is a track boss and the second matching portion 10x is a track groove for illustration.

[0069] The dimension of the track groove along the first direction is slightly larger than that of the track boss, so that the track boss can move in the track groove at a certain inclination angle.

[0070] The track boss is disposed close to the first end 210b, that is, the distance between the track boss and the first end 210b is smaller than the distance between the track boss and the second end 210c.

[0071] Please refer to Figure 2 and Figure 3 When the mating end 10n abuts against the first end 210b and the assembly end 10m rotates around the mating end 10n toward the installation area 210a, the inclination angle between the track boss and the track groove is relatively large, so that the track boss cannot completely enter the track groove, so that interference can be formed between the two.

[0072] Please refer to Figure 2 and Figure 4 In the process where the assembly end 10m abuts against the second end 210c and the mating end 10n rotates around the assembly end 10m toward the direction of entering the installation area 210a, after rotating to a position where the track groove and the track boss are close to each other, the inclination angle between the track groove and the track boss is relatively small, and the track boss can gradually enter the track groove. The mating end 10n continues to rotate around the assembly end 10m toward the direction of entering the installation area 210a, and the track boss can move in the track groove.

[0073] It can be understood that after the setting position and specific size of one of the track boss and the track groove are determined, the setting position and specific size of the other one can be obtained based on simulation.

[0074] The first matching portion 210d and the second matching portion 10x are matched with each other by using the structure of a track boss and a track groove, so that the structure of the first matching portion 210d and the second matching portion 10x is relatively simple and easy to implement.

[0075] See also Figure 5 , Figure 8 and Fig. 9 In one embodiment, the first mating portion 210d is a track boss, and along the first direction, the distance between the track boss and the first end 210b is smaller than the distance between the heating component 220 and the first end 210b, and the spacing between the side of the track boss facing the first end 210b and the side of the heating component 220 facing the first end 210b is not less than 4 mm.

[0076] The distance between the side of the track boss facing the first end 210b and the side of the heating assembly 220 facing the first end 210b is as follows: Fig. 9 As shown in L1 in FIG. L1 is not less than 4 mm. For example, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, etc.

[0077] The specific direction of the third direction is not limited. For example, the third direction is Figure 2 and Figure 8 The direction shown in d3.

[0078] Please refer to Figure 2 and Figure 3 In the first assembly method, the rotation center of the assembly end 10m around the mating end 10n is close to the first end 210b, and the atomized medium component 100, the rotation center and the wall surface of the installation area 210a are equivalent to defining a triangle. Since the track boss is closer to the first end 210b than the heating component 220, the interference position of the track boss and the track groove is also closer to the first end 210b than the heating component 220. After the track boss and the track groove are in the interference position, the space at the position of the heating component 220 is relatively large, which is conducive to reducing the size of the heating component 220 inserted into the heating area 10a, and can even prevent the heating component 220 from entering the heating area 10a, thereby reducing the probability of the heating component 220 squeezing the strip medium 20 in the heating area 10a.

[0079] See also Figure 5 , Figure 8 and Fig. 9 In one embodiment, the first matching portion 210d is a track boss, the extension direction of the heating component 220 is a third direction, and along the third direction, the ratio of the size of the track boss to the size of the wall of the heating component 220 protruding from the installation area 210a is not less than 0.7.

[0080] The specific direction of the third direction is not limited. For example, the third direction is Figure 2 and Figure 8 The direction shown in d3.

[0081] The dimensions of the track boss are as follows: Fig. 9 As shown in L2 in FIG. 1 , the size of the heating assembly 220 protruding from the wall of the installation area 210a is as follows: Fig. 9 As shown in L3 in FIG. The ratio of L2 to L3 is not less than 0.7. For example, it is 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, etc.

[0082] The ratio of L2 to L3 is not less than 0.7, and the track boss has a sufficient size compared to the portion of the wall of the heating component 220 protruding from the mounting area 210a. Figure 2 and Figure 3In the first assembly method, when the assembly end 10m rotates around the mating end 10n and the track boss and the track groove are in an interference position, the rotation angle of the assembly end 10m around the mating end 10n will not be too large. Therefore, sufficient space can be formed between the shell 10 and the wall of the installation area 210a to accommodate the heating component 220, which is beneficial to reduce the size of the heating component 220 inserted into the heating area 10a, and can even prevent the heating component 220 from entering the heating area 10a, thereby reducing the probability of the heating component 220 squeezing the strip medium 20 in the heating area 10a.

[0083] See also Figures 2 to 4 In one embodiment, the side walls of the track boss on opposite sides along the first direction and the side walls of the track groove on opposite sides along the first direction are both arc-shaped. When the shell 10 is assembled in the installation area 210a, the side walls of the track boss on opposite sides along the first direction and the side walls of the track groove on opposite sides along the first direction are bent toward the side away from the second end 210c.

[0084] The side walls of the track boss on opposite sides along the first direction and the side walls of the track groove on opposite sides along the first direction are bent toward the side away from the second end 210c. In other words, the middle area of ​​the arcuate side wall of the track boss is close to the first end 210b, and the two ends are close to the second end 210c. The arcuate side wall of the track groove is similar.

[0085] See also Figure 2 and Figure 4 In the second assembly mode, the assembly end 10m is against the second end 210c, that is, the track groove or track boss also rotates around the second end 210c.

[0086] In this embodiment, the center of the arcuate side wall of the track boss and the center of the arcuate side wall of the track groove can both be located at the second end 210c. In this way, when the atomized medium component 100 is assembled using the second assembly method, the track boss can move in the track groove. When the atomized medium component 100 is assembled using the first assembly method, the side wall of the track boss and the side wall of the track groove will interfere with each other.

[0087] In some other embodiments, the side walls of the track boss and the side walls of the track groove may also be planar structures, and it is only necessary to ensure that when the atomizing medium assembly 100 is assembled using the first assembly method, the side walls of the track boss and the side walls of the track groove can interfere with each other, and when they are in the interference position, the heating assembly 220 is separated from the strip medium 20 in the heating area 10a; and when the atomizing medium assembly 100 is assembled using the second assembly method, the track boss can move in the track groove so that the atomizing medium assembly 100 can be assembled in the installation area 210a.

[0088] See also Figures 5 to 7In one embodiment, when the housing 10 is assembled in the installation area 210 a , the strip medium 20 in the heating area 10 a is located on a side of the heating assembly 220 facing the first end 210 b .

[0089] See also Figure 2 and Figure 4 It is understandable that, since the strip medium 20 in the heating area 10a needs to be located on the side of the heating component 220 facing the first end 210b, when the atomized medium component 100 is assembled using the second assembly method, even if the heating component 220 contacts the strip medium 20 first, the top of the heating component 220 is pressed on the width surface of the strip medium 20, that is, it will not touch the thickness surface of the strip medium 20. The width dimension is greater than the thickness dimension, and after the heating component 220 is pressed on the width surface, the contact area between the strip medium 20 and the heating component 220 is larger, and the pressure drop is smaller, thereby reducing the probability that the strip medium 20 is squeezed by the heating component 220 and deformed or broken.

[0090] Furthermore, after the heating component 220 is squeezed onto the width surface of the strip medium 20, while the mating end 10n continues to rotate around the assembly end 10m, the heating component 220 can push the strip medium 20 in the heating area 10a to move a distance along the first direction toward the side close to the first end 210b, so that the strip medium 20 can be stably pressed onto the heating component 220, thereby enabling the heating component 220 to better heat the strip medium 20.

[0091] See also Figures 2 to 4 In one embodiment, the thickness direction of the heating element 220 is parallel to the first direction.

[0092] It should be noted that the dimensions of different components in the three directions in the same absolute coordinate system are different. Generally, the length, width and thickness of the object are determined according to the dimensions of the object extending in the three directions, with length>width>thickness.

[0093] That is, the thickness direction is the direction in which the heating component 220 has the smallest size. By setting the thickness direction of the heating component 220 to be parallel to the first direction, the size of the heating component 220 in the first direction is smaller, thereby reducing the probability of squeezing the strip medium 20 in the heating area 10a and causing the strip medium 20 to deform or break.

[0094] See also Figures 2 to 4 In one embodiment, the thickness direction of the strip medium 20 located in the heating area 10a is parallel to the first direction.

[0095] The thickness direction is the direction in which the size of the strip medium 20 is the smallest. By setting the thickness direction of the strip medium 20 in the heating area 10a to be parallel to the first direction, the size of the strip medium 20 in the heating area 10a in the first direction is smaller, thereby reducing the probability that the strip medium 20 in the heating area 10a is squeezed by the heating component 220 and deformed or broken.

[0096] See also Fig.10 and Fig.11 In one embodiment, the shell 10 further has a storage space 10b and a receiving space 10c, and the storage space 10b is separated from the receiving space 10c. The atomized medium assembly 100 also includes a storage disk 30 disposed in the storage space 10b and a receiving disk 40 disposed in the receiving space 10c. 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 receiving disk 40 after passing through the heating area 10a.

[0097] Specifically, see Fig.11 The housing 10 includes a first shell 11 and a second shell 12. The first shell 11 includes a shell body 112 and a boss 111. The shell body 112 and the second shell 12 define a storage space 10b and a receiving space 10c.

[0098] 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, 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 and other odors to a certain extent.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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, by providing a storage tray 40 in the storage space 10c for rolling up the used strip medium 20, the generation of debris can be further reduced by rolling the used strip medium 20 into a roll. 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.

[0103] See also Figure 2 , Figure 3 , Fig.10 and Fig.11 In one embodiment, the host 200 further includes a driving shaft 240 . When the housing 10 is assembled in the mounting area 210 a , at least a portion of the driving shaft 240 extends into the storage space 10 c and is drivingly connected to the storage tray 40 .

[0104] The drive shaft 240 is disposed in the installation area 210a, and a drive connection hole 112a is provided on the shell 10 (specifically, a drive connection hole 112a is provided on the shell body 112). The drive shaft 240 passes through the drive connection hole 112a and is drive-connected to the storage disk 40. The drive shaft 240 rotates to drive the storage disk 40 to rotate. Through the rotation of the storage disk 40, the used strip medium 20 can be wound on the storage disk 40. At the same time, the storage disk 30 follows the storage disk 40 and is driven, so that the strip medium 20 stored on the storage disk 30 is unwound.

[0105] See also Figure 2 , Figures 5 to 7 , Fig.10 and Fig.11 The housing 10 also has an air outlet channel 111a, one end of which is connected to the heating area 10a, and the other end of which is connected to the outside. The aerosol generated in the heating area 10a can flow out through the air outlet channel 111a, so as to be used by the user. The aerosol generating device also includes 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 area 10a through the suction piece 300.

[0106] The method of forming the air outlet channel 111a in the housing 10 is not limited. Fig.10 and Fig.11The 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 .

[0107] The shape of the protrusion 111 is not limited. For example, it can be cylindrical, square, etc. For example, see Fig.10 and Fig.11 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.

[0108] 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.

[0109] The protruding column 111 can facilitate the connection of the suction member 300 to the housing 10, thereby achieving the suction of aerosol.

[0110] 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.
