In other cases, for the sake of brevity of the description of the present invention, detailed descriptions of well-known systems, devices, circuits and methods are omitted.

[0020] FIG. 1 shows a first embodiment of the aerosol generation system of the present invention. The aerosol generation system 100 generates an aerosol for the user to inhale. The aerosol generated by the aerosol generation system 100 has excellent taste and user experience.

[0021] The aerosol generation system 100 includes an aerosol generation substrate assembly 10 and an aerosol generation device 20. The aerosol generation substrate assembly 10 is attached to the aerosol generation device 20 and is used to generate aerosols when heated. To facilitate the replacement of the aerosol generation substrate assembly 10, the aerosol generation substrate assembly 10 is detachably connected to the aerosol generation device 20. In other embodiments, the connection may be an integrated fixed connection. The aerosol generation device 20 generates and discharges aerosols by heating and vaporizing the aerosol generation substrate 12 within the aerosol generation substrate assembly 10.

[0022] As shown in Figures 2 to 4, in this embodiment, the aerosol generating substrate assembly 10 includes a housing 11 and an aerosol generating substrate 12. The housing 11 is used to house the aerosol generating substrate 12. The aerosol generating substrate 12 vaporizes under heated conditions to generate an aerosol. It should be understood that in other embodiments, the housing 11 may be omitted. The aerosol generating substrate 12 may be directly attached to the aerosol generating device 20.

[0023] In this embodiment, the housing 11 is a transparent structure, for example, a transparent plastic container. Of course, it should be understood that in some embodiments, the housing 11 is not limited to a transparent structure, but may be a non-transparent structure such as a non-transparent plastic container or a metal container. In some embodiments, the housing 11 includes a first housing 11a and a second housing 11b, and the shape and dimensions of the first housing 11a and the second housing 11b are equivalent. In some embodiments, the first housing 11a and the second housing 11b are substantially rectangular parallelepipeds. The first housing 11a and the second housing 11b are not limited to a rectangular parallelepiped shape, but may be columnar, square-pronged, or irregularly shaped. Inside the first housing 11a and the second housing 11b, a cavity 110 with an opening structure is formed, and the joining side of the first housing 11a and the joining side of the second housing 11b can be fitted together. The first housing 11a and the second housing 11b can be fixed together by a connecting structure such as a screw member, an engaging member, or a hinge structure. In some embodiments, this connecting structure may be omitted, and the first housing 11a and the second housing 11b may be connected by conventional ultrasonic technology.

[0024] In this embodiment, the aerosol generating substrate assembly 10 further includes an intake hole 111. The intake hole 111 is installed in the housing 11 and communicates with the cavity 110, allowing outside air to be introduced from the cavity 110 into the vaporization cavity 151. Specifically, there are two intake holes 111, each installed on an opposing side of the housing 11. The intake hole 111 is a circular through-hole. Semicircular through-holes are provided in the first housing 11a and the second housing 11b, and by joining the first housing 11a and the second housing 11b, the semicircular through-holes in the first housing 11a and the second housing 11b form a circular intake hole 111. In other embodiments, the intake port 111 is not limited to being provided in the first housing 11a and the second housing 11b, but may be provided in only the first housing 11a or only the second housing 11b. In other embodiments, the intake port 111 is not limited to being circular, but may be rectangular or of other shapes.

[0025] As shown in Figures 5 to 7, in this embodiment, the aerosol generating substrate 12 is set up as a windable strip and is movable. In some embodiments, the thickness T of the aerosol generating substrate 12 is 0.15 mm to 0.35 mm (including the values ​​at both ends). In this embodiment, the thickness T of the aerosol generating substrate 12 is set to 0.25 mm. In this embodiment, the aerosol generating substrate 12 includes a strip-shaped substrate 121 and a substrate layer 122. The strip-shaped substrate 121 is used to support the substrate layer 122. The substrate layer 122 is formed on the strip-shaped substrate 121, specifically by applying a vaporizing medium onto the strip-shaped substrate 121. The vaporizing medium is a solidifiable liquid vaporizing medium, and may be a paste-like or solid vaporizing medium. In other embodiments, the base layer 122 is not limited to being formed by coating a vaporizing medium, but may also be formed by, for example, pressing or adhering a vaporizing medium onto a strip-shaped substrate 121.

[0026] In this embodiment, the strip-shaped base 121 is installed in an elongated shape and has a first surface 121a and a second surface 121b installed in opposite directions. Both the first surface 121a and the second surface 121b are defined by the long side and short side of the strip-shaped base 121. Of these, the first surface 121a is on which the base material layer 122 is placed. In some embodiments, the strip-shaped base 121 is a metal foil with good thermal conductivity, such as aluminum foil or copper foil. Of course, in other embodiments, the strip-shaped base 121 is not limited to metal foil, but may be a metal mesh, and the metal mesh may be formed by weaving metal wires, or it may be formed by providing a plurality of through holes in the metal foil.

[0027] Specifically, the base layer 122 is formed over the entire surface of the first surface 121a of the strip-shaped substrate 121 by uniformly applying a vaporizing medium along the longitudinal direction of the strip-shaped substrate 121. In some embodiments, the thickness of the base layer 122 is the same at any position on the strip-shaped substrate 121. Of course, in other embodiments, the thickness of the base layer 122 may differ at at least two positions on the strip-shaped substrate 121. In other embodiments, multiple base layers 122 are formed by stepwise applying a vaporizing medium to the first surface 121a of the strip-shaped substrate 121. The multiple base layers 122 are arranged at equal intervals and have the same length in the longitudinal direction of the strip-shaped substrate 121. It should be understood that in other embodiments, the lengths of at least two base layers 122 in the longitudinal direction of the strip-shaped substrate 121 may differ.

[0028] In this embodiment, the aerosol generating substrate assembly 10 further includes a first storage structure 13 for housing the aerosol generating substrate 12 before heating. The first storage structure 13 is mounted between a first housing 11a and a second housing 11b and connected to the first housing 11a and the second housing 11b. In other embodiments, the first storage structure 13 is not limited to being mounted on the housing 11, but may be directly mounted on the aerosol generating device 20.

[0029] In this embodiment, the first storage structure 13 is a storage tray 131 for containing the aerosol generating substrate 12 before heating, the aerosol generating substrate 12 before heating being wound around the storage tray 131, and the aerosol generating substrate 12 before heating being discharged by the rotation of the storage tray 131. In some embodiments, the storage tray 131 includes a first tray 1311 and a second tray 1312. The first tray 1311 and the second tray 1312 are substantially circular in shape and have substantially the same radial dimensions. The first tray 1311 and the second tray 1312 are connected by a hollow reel. The reel may be formed on the central axis of the first tray 1311 and / or the second tray 1312, or it may be installed independently, with both ends connected to the first tray 1311 and the second tray 1312, respectively. The radial dimension of the reel is smaller than the radial dimensions of the first plate 1311 and the second plate 1312, and the aerosol-generating substrate 12 before heating is wound onto the reel. In other embodiments, it should be understood that the first plate 1311 and the second plate 1312 are not limited to circular but may be rectangular. The first plate 1311 and the second plate 1312 are used to prevent the aerosol-generating substrate 12 from falling off during the winding process. In some embodiments, the first plate 1311 and the second plate 1312 may be omitted. In some embodiments, the storage plate 131 is rotatably connected to the first housing 11a and / or the second housing 11b. The rotation of the storage plate 131 enables the winding and unwinding of the aerosol-generating substrate 12 before heating, thereby enabling the storage and transmission of the aerosol-generating substrate 12 before heating.

[0030] In this embodiment, the aerosol generating substrate assembly 10 further includes a second storage structure 14 used to accommodate the strip-shaped substrate 121 of the vaporized aerosol generating substrate 12, that is, to accommodate the strip-shaped substrate 121 from which the substrate layer 122 has been removed. In some embodiments, the storage plate 141 is installed between the first housing 11a and the second housing 11b and connected to the first housing 11a and the second housing 11b. In other embodiments, the second storage structure 14 is not limited to being attached to the housing 11, but may be directly attached to the aerosol generating device 20.

[0031] In this embodiment, the second storage structure 14 further includes a storage plate 141 for storing the heated aerosol-generating substrate 12, the heated aerosol-generating substrate 12 being wound around the storage plate 141. In some embodiments, the storage plate 141 includes a third plate 1411 and a fourth plate 1412. Both the third plate 1411 and the fourth plate 1412 are circular in shape and have substantially the same radial dimensions. The third plate 1411 and the fourth plate 1412 are spaced apart and connected by a hollow reel. The reel may be mounted on the central axis of the third plate 1411 and / or the fourth plate 1412, or it may be mounted independently, with both ends connected to the third plate 1411 and the fourth plate 1412, respectively. The reel is cylindrical in shape, with a radial dimension smaller than that of the third plate 1411 and the fourth plate 1412, and is used to wind up the heated strip-shaped substrate 121. In some embodiments, the third plate 1411 and the fourth plate 1412 are not limited to circular shapes but may be rectangular, and it is possible to prevent the strip-shaped substrate 121 from falling off. In some embodiments, the third plate 1411 and the fourth plate 1412 may be omitted. In some embodiments, the storage plate 141 is rotatably connected to the first housing 11a and / or the second housing 11b. The aerosol generating substrate 12 is wound up by the rotation of the storage plate 141.

[0032] In this embodiment, the storage plate 141 includes a drive pulley, and the storage plate 131 includes a driven pulley, the driven pulley operating in accordance with the drive pulley. Since the aerosol generating substrate 12 is wound around the storage plate 131 and the storage plate 141, the storage plate 131 is rotatable in accordance with the storage plate 141. When the storage plate 131 and the storage plate 141 rotate simultaneously, the vaporized aerosol generating substrate 12 is wound onto the storage plate 141 while the aerosol generating substrate 12 is fed out before heating. In other embodiments, the storage plate 141 is not limited to a drive pulley and may include a driven pulley, and the storage plate 131 is not limited to a driven pulley and may include a drive pulley. In some embodiments, the storage plate 131 and the storage plate 141 may be installed to rotate independently, that is, the storage plate 131 and the storage plate 141 may be driven and rotated by two different sets of drive structures.

[0033] In this embodiment, the dimensions of the storage space of the second storage structure 14 are larger than the dimensions of the storage space of the first storage structure 13. Specifically, the radial dimensions of the third plate 1411 and the fourth plate 1412 are both larger than the radial dimension of the first plate 1311 and larger than the radial dimension of the second plate 1312. Therefore, the dimensions of the storage space formed between the third plate 1411 and the fourth plate 1412 are larger than the dimensions of the storage space formed between the second plate 1312 and the first plate 1311. Of course, in other embodiments, the cross-sectional dimensions of the reel may be set smaller than the cross-sectional dimensions of the reel, and it should be understood that the dimensions of the storage space formed between the third plate 1411 and the fourth plate 1412 are larger than the dimensions of the storage space formed between the second plate 1312 and the first plate 1311. In other embodiments, the dimensions of the storage space of the second storage structure 14 may be less than or equal to the dimensions of the storage space of the first storage structure 13.

[0034] As shown in Figures 6 and 8, in this embodiment, the aerosol generating substrate assembly 10 further includes a vaporization shell 15, a portion of which is installed in the housing 11. The vaporization shell 15 includes a main body portion 15a and an extension portion 15b installed on the main body portion 15a, and the main body portion 15a is fitted into and attached to the housing 11.

[0035] A vaporization cavity 151 having an inlet 152 and an outlet 153 is formed inside the vaporization shell 15, and the inlet 152 and outlet 153 are installed in the vaporization shell 15. The vaporization cavity 151 is formed inside the main body 15a and is defined by a space for heating the aerosol-generating substrate 12 of the heating structure 22. The inlet 152 is installed on one side of the main body 15a, communicates with the vaporization cavity 151, and is used to introduce the aerosol-generating substrate 12 into the vaporization cavity 151 before heating. In some embodiments, the inlet 152 is installed opposite one of the intake holes 111 so that it can communicate with the corresponding intake hole 111. The outlet 153 is installed on the other side of the main body 15a, communicates with the vaporization cavity 151, and is used to discharge the vaporized aerosol-generating substrate 12. In some embodiments, the outlet 153 is positioned opposite the other intake port 111 so as to be able to communicate with the corresponding intake port 111. In other embodiments, it should be understood that only the inlet 152 or the outlet 153 may be connected to the intake port 111. The inlet 152 and outlet 153 are positioned opposite each other and are both located in or near the plane where the center of the vaporization cavity 151 is located. The extension 15b is positioned on the main body 15a and protrudes from the housing 11, and is used to connect to the nozzle assembly 30. The extension 15b is columnar with both ends penetrating, and an exhaust passage 154 is formed inside it, communicating with the vaporization cavity 151 to discharge the aerosol generated by vaporization. The inlet 152 and outlet 153 are positioned on different sides of the exhaust passage 154, for example, on opposing sides of the exhaust passage 154. Of course, it should be understood that in other embodiments, the inlet 152 and outlet 153 may be located on adjacent sides of the exhaust passage 154. In other embodiments, the inlet 152 and outlet 153 may be located on the same side of the exhaust passage 154. In some embodiments, the vaporization cavity 151 has an opening 155. The opening 155 is formed on the side of the main body 15a facing the heating structure 22. The heating structure 22 is insertable into the vaporization cavity 151 through the opening 155.

[0036] In this embodiment, the vaporization cavity 151 may have an irregular shape. Of course, in other embodiments, the shape of the vaporization cavity 151 may be a regular shape such as a cube, cone, or cylinder. The height H3 of the vaporization cavity 151 is 6.0 mm to 7.0 mm (including both values). Specifically, in some embodiments, the height H3 of the vaporization cavity 151 is set to 6.7 mm. Of course, in other embodiments, the height H3 of the vaporization cavity 151 is not limited to 6.7 mm. The direction of the height H3 of the vaporization cavity 151 is the same as the direction of the thickness of the aerosol generating substrate 12 within the vaporization cavity 151, that is, it is perpendicular to the direction of movement of the aerosol generating substrate 12.

[0037] In this embodiment, a heating region 1510 is formed in the vaporization cavity 151. The heating region 1510 is the region where the heating structure 22 is located, that is, the region where the aerosol generating substrate 12 is heated and vaporized. The aerosol generating substrate 12 is movably perforated in the heating region 1510 and is heated as it passes through the heating region 1510. In some embodiments, the heating region 1510 has a starting point and an ending point in the direction in which the aerosol generating substrate 12 is perforated in the vaporization cavity 15. In this embodiment, the starting point and the ending point are located on opposite sides of the heating region 1510, with the starting point facing the inlet 152 and the ending point facing the outlet 153. The aerosol generating substrate 12 passes through the heating region 1510 by moving sequentially from the starting point to the ending point. In some embodiments, by making the width W of the vaporization cavity 151 greater than or equal to the width of the heating region 1510, and by making the width of the heating region 1510 greater than the width w of the aerosol generating substrate 12, sufficient heating of the aerosol generating substrate 12 in the heating region 1510 can be ensured. In some embodiments, by making the length L1 of the vaporization cavity 151 greater than or equal to the length L2 of the heating region 1510, that is, by making the length of the vaporization cavity 151 greater than the line segment connecting the starting point and ending point of the heating region 1510, the heating of the aerosol generating substrate 12 can be concentrated in the vaporization cavity 151, ensuring that the aerosol generated by heating collects in the vaporization cavity 151 and preventing aerosol leakage. Of these, L1 is 10 mm and L2 is 9 mm.

[0038] In this embodiment, the ratio of the height H1 of the inlet 152 to the height H3 of the vaporization cavity 151 is set to 0.12 to 0.40, and the height H1 of the inlet 152 is made greater than the thickness T of the aerosol generating substrate 12 to facilitate the entry of the aerosol generating substrate 12. By setting the ratio of the height H1 of the inlet 152 to the height H3 of the vaporization cavity 151 to 0.12 to 0.40, it is possible to prevent the pressure in the vaporization cavity 151 from decreasing due to the inlet 152 being too small, thereby preventing the generation of suction turbulence and avoiding adverse effects on the suction experience. Furthermore, by setting the inlet 152 to an excessive size, it is possible to prevent the aerosol generated by heating the aerosol generating substrate 12 in the vaporization cavity 151 from leaking out of the inlet 152, i.e., aerosol leakage. The direction of the height H1 of the inlet 152 is the same as the direction of the thickness T of the aerosol generating substrate 12, that is, it is perpendicular to the direction of movement of the aerosol generating substrate 12 to the vaporization cavity 151. In some embodiments, the height H1 of the inlet 152 is 0.8 mm to 2.5 mm (including both values), and is specifically set to 1.2 mm.

[0039] In this embodiment, the ratio of the height H2 of the outlet 153 to the height H3 of the vaporization cavity 151 is set to 0.12 to 0.40, and is greater than the thickness T of the aerosol generating substrate 12, thereby facilitating the discharge of the aerosol generating substrate 12. By setting the ratio of the height H2 of the outlet 153 to the height H3 of the vaporization cavity 151 to 0.12 to 0.40, it is possible to prevent the pressure in the vaporization cavity 151 from decreasing due to an insufficient size of the outlet 153, thereby preventing the generation of suction turbulence and avoiding adverse effects on the suction experience. Furthermore, by setting an excessive size of the outlet 153, it is possible to prevent the aerosol generated by heating the aerosol generating substrate 12 in the vaporization cavity 151 from leaking out of the outlet 153, i.e., aerosol leakage. Note that the direction of the height H2 of the outlet 153 is the same as the direction of the thickness of the aerosol generating substrate 12, i.e., it is perpendicular to the direction of movement of the aerosol generating substrate 12 into the vaporization cavity 151. In some embodiments, the height H2 of the outlet 153 is 0.8 mm to 2.5 mm (including both values), specifically, the outlet 153 is equal to the height H1 of the inlet 152. In some embodiments, the height H2 of the outlet 153 is set to 1.2 mm.

[0040] In this embodiment, the dimensions of the inlet 152 and outlet 153 are determined by the width of the aerosol generating substrate 12. In some embodiments, by setting the width W of the inlet 152 to be larger than the width w of the aerosol generating substrate 12, the aerosol generating substrate 12 can easily enter the vaporization cavity 151 from the inlet 152. In some embodiments, by setting the width W of the outlet 153 to be larger than the width w of the aerosol generating substrate 12, the aerosol generating substrate 12 can be easily discharged from the outlet 153.

[0041] In this embodiment, the exhaust passage 154 is installed in an elongated manner perpendicular to the direction of movement of the aerosol generating substrate 12 and is columnar or conical in shape. In some embodiments, the exhaust passage 154 may be formed by opening an exhaust port in the vaporization shell 15. The exhaust passage 154 has an axial direction parallel to the direction of extension of the central axis of the exhaust passage 154. In this embodiment, the axial direction is the same as the direction of extension of the exhaust passage 154. The aerosol generated by heating the aerosol generating substrate 12 is discharged outward along the axial direction of the exhaust passage 154. The axial direction is installed non-parallel to the direction of movement of the aerosol generating substrate 12 in the vaporization cavity 151. That is, the axial direction of the exhaust passage forms a predetermined angle α with respect to the direction of movement of the aerosol generating substrate 12 in the vaporization cavity 151, and the predetermined angle α is in the range of 0° to 180°. This improves the aerosol discharge efficiency and ensures the aerosol discharge effect.

[0042] Furthermore, the axial direction of the exhaust passage 154 forms a predetermined angle α with respect to the drilling direction of the aerosol generating substrate 12 in the heating region. Specifically, the central axis of the exhaust passage 154 forms the predetermined angle α with respect to the line segment connecting the starting point and ending point of the heating region 1510. In some embodiments, the predetermined angle α is set to 90°. That is, the exhaust passage 154 is installed in the axial direction of the heating region 1510, and the axis of the exhaust passage 154 coincides with the axial direction of the heating region 1510. This ensures that the exhaust passage 154 is installed in the direction of aerosol discharge when the aerosol generating substrate 12 is heated in the heating region 1510, and the aerosol generated by the aerosol generating substrate 12 is discharged rapidly and in large quantities from the exhaust passage 154, thereby improving the aerosol discharge rate, ensuring the taste of the aerosol after discharge, and improving the user experience.

[0043] As shown in Figures 5 and 6, in this embodiment, the aerosol generating substrate assembly 10 further includes a guide structure 16. The guide structure 16 is installed in the housing 11 and is used to guide the aerosol generating substrate 12. In some embodiments, the guide structure 16 includes a first guide roller 161, a second guide roller 162, a third guide roller 163, and a fourth guide roller 164, which are installed in sequence. Of these, the first guide roller 161 is installed on one side of the first storage structure 13 and is used to guide the progress of the aerosol generating substrate 12 discharged from the first storage structure 13. The second guide roller 162 and the third guide roller 163 are installed on opposite sides of the vaporization shell 15, respectively. Of these, the second guide roller 162 is located on the side of the inlet 152 away from the outlet 153, and the third guide roller 163 is located on the side of the outlet 153 away from the inlet 152, and the second guide roller 161 and the third guide roller 163 make the aerosol generating substrate 12 adhere more tightly to the heating structure 22. The fourth guide roller 164 is located on one side of the second storage structure 14. The line segment connecting the fourth guide roller 164 and the third guide roller 163 is set to form an angle with respect to the line segment connecting the second guide roller 162 and the third guide roller 163, and this angle is in the range of 0° to 180°. When the storage tray 131 and the storage tray 141 rotate, the aerosol generating substrate 12 before heating enters the vaporization cavity 151 via the first guide roller 161, the second guide roller 162, and the inlet 152. After vaporization, the storage plate 131 and the storage plate 141 continue to rotate, causing the vaporized aerosol-generating substrate 12 to be discharged from the outlet 153, pass sequentially through the third guide roller 163, and be stored in the storage plate 141. In some embodiments, the guide structure 16 is not limited to including four guide rollers, but may include three guide rollers. In some embodiments, the guide structure 16 is not limited to rollers, but may be any structure capable of guiding the movement of the aerosol-generating substrate 12.

[0044] Referring to Figures 1-3 and 9-10, the aerosol generating apparatus 20 includes a body 21 and a heating structure 22. The body 21 is used to house the aerosol generating substrate assembly 10. The heating structure 22 is attached to the body 21 and is insertable into the aerosol generating substrate assembly 10, and is used to heat the aerosol generating substrate 12 within the aerosol generating substrate assembly 10 to generate aerosols.

[0045] In this embodiment, the machine body 21 includes a housing 211 and a cover 212. The housing 211 includes a first housing 211a and a second housing 211b. The first housing 211a is installed in the second housing 211b. The first housing 211a is provided with a housing cavity 2111 for housing an aerosol generating substrate assembly 10. An assembly access opening 2112 is provided in the side wall of the first housing 211a for loading the aerosol generating substrate 12 into the housing cavity 2111. The cover 212 is detachably installed in the assembly access opening 2112 and closes the housing cavity 2111. Opening the cover 212 allows for removal and replacement of the aerosol generating substrate assembly 10.

[0046] In this embodiment, the heating structure 22 is attached to the first housing 211a, located on the bottom wall of the containment cavity 2111, and protruding into the containment cavity 2111. When the aerosol generating substrate assembly 10 is attached to the containment cavity 2111, the heating structure 22 is inserted into the vaporization shell 15 of the aerosol generating substrate assembly 10 and used to heat the aerosol generating substrate 12 before it enters the vaporization cavity 151. In some embodiments, the heating structure 22 includes a base 221 and a heating element 222, the base 221 being attached to the bottom wall of the containment cavity 2111, and the heating element 222 being attached to the base 221. In some embodiments, the heating element 222 includes a metal heating element. Of course, in other embodiments, the heating element 222 includes a ceramic heating element, a glass heating element. The shape of the heating element 222 is plate-like, linear, or columnar. In other embodiments, the heating structure 22 may be an electromagnetic heating structure and is not limited to being inserted into the vaporization shell 15.

[0047] In this embodiment, the aerosol generating apparatus 20 further includes a drive assembly 23. The drive assembly 23 is mounted on the machine body 21, specifically between the first housing 211a and the second housing 211b, and is partially insertable into the housing cavity 2111. Thus, the drive assembly 23 is connected to the second storage structure 14 or the first storage structure 13 and is used to feed the aerosol generating substrate 12 in the aerosol generating substrate assembly 10 into the heating structure 22. In some embodiments, the drive assembly 23 is an electrically driven structure, for example, a motor or a reduction gearbox. The output shaft of the drive assembly 23 is inserted into the housing cavity 2111 from the side opposite to the housing cavity 2111 of the first housing 211a and connected to the second housing structure 14 or the first housing structure 13, i.e., connected to the storage plate 131 or storage plate 141, thereby rotating the storage plate 131 and the second storage roller 132. Of course, it should be understood that in other embodiments, the drive assembly 23 is not limited to an electric drive structure, but may be a manual drive structure such as a handle or handwheel.

[0048] In this embodiment, the aerosol generating apparatus 20 further includes a sealing structure 24. The sealing structure 24 is installed in the housing cavity 2111 and is located on the outer circumference of the heating structure 22. Specifically, the sealing structure 24 is a sealing ring. When the aerosol generating substrate assembly 10 is loaded into the housing cavity 2111, the sealing structure 24 can seal the gap between the end face where the opening 155 of the vaporization cavity 151 of the aerosol generating substrate assembly 10 is located and the bottom wall of the housing cavity 2111, thereby preventing aerosol leakage.

[0049] In this embodiment, the aerosol generator 20 further includes a power supply 25. The power supply 25 is installed in the housing 211 and specifically located between the first housing 211a and the second housing 211b. The power supply 25 is used to supply power to the drive assembly 23 and the heating structure 22. In some embodiments, the power supply 25 is a battery or a chemical reactant.

[0050] In this embodiment, the aerosol generator 20 further includes a main control board 26. The main control board 26 is installed in the housing 211, specifically located between the first housing 211a and the second housing 211b. The main control board 26 is connected to a power supply 25, a drive assembly 23, and a heating structure 22.

[0051] In this embodiment, the aerosol generation system 100 further includes a nozzle assembly 30 assembled on the vaporization shell 15. Specifically, the nozzle assembly 30 covers the extension 15b and allows the user to aspirate the aerosol discharged from the vaporization cavity 151 using the nozzle assembly 30. In some embodiments, the nozzle assembly 30 is substantially cylindrical. Of course, in other embodiments, the nozzle assembly 30 is not limited to a cylindrical shape and may be flattened columnar or have other shapes.

[0052] Figures 11 to 13 show a second embodiment of the aerosol generation system 100 of the present invention. The difference from the first embodiment is that in this embodiment, the first housing 11a is provided with a housing portion 112 that protrudes inward, and a housing groove for housing the heating structure 22 is defined on the side of the housing portion 112 opposite to the second housing 11b.

[0053] In this embodiment, the vaporization shell 15 is integrally molded with the housing 11, that is, integrally molded with either the first housing 11a or the second housing 11b. The main body portion 15a is formed in the first housing 11a and is installed so as to gradually narrow toward the extension portion 15b and widen toward the direction away from the extension portion 15b. The main body portion 15a is installed opposite the housing portion 112 with a gap between them, and the gap between them forms a passage for moving the aerosol generating substrate 12. The main body portion 15a and the housing portion 112 define the vaporization cavity 151, the inlet 152, and the outlet 153, with the inlet 152 and the outlet 153 located on opposite sides of the vaporization cavity 151. In this embodiment, the height H2 of the outlet 153 is greater than the height H1 of the inlet 152, and selectively, the height H2 of the outlet 153 is set to 1.1 mm and the height H1 of the inlet 152 is set to 0.8 mm. The reason for setting the height H2 of the outlet 153 to be greater than the height H1 of the inlet 152 is that after heating the aerosol generating substrate 12, the substrate layer 122 separates from the strip-shaped substrate 121 or expands and hardens, and by setting the height H2 of the outlet 153 to be greater than the height H1 of the inlet 152, the discharge of the heated aerosol generating substrate 12 can be facilitated. In this embodiment, the width D of both the inlet 152 and the outlet 153 is greater than the width w of the aerosol generating substrate 12. In some embodiments, selectively, the width D of the inlet 152 and the outlet 153 is set to 7.5 mm, and the width w of the aerosol generating substrate 12 is set to 5 mm.

[0054] In this embodiment, the housing 11 has a storage space 110a and a storage space 110b. Specifically, the space where the first storage structure 13 is located forms the storage space 110a, and the space where the second storage structure 14 is located forms the storage space. In this embodiment, at least one barrier structure 17 is formed between the storage space 110a, the storage space 110b, and the vaporization cavity 151. Specifically, in this embodiment, at least one barrier structure 17 includes a first barrier structure 171 installed between the storage space 110a and the storage space 110b. The first barrier structure 171 is an S-shaped partition separating the storage space 110a and the storage space 110b, and the partition is integrally molded with the first housing 11a or the second housing 11b and is in close contact with the first housing 11a and the second housing 11b, preventing residue and odor generated after the vaporization of the base material layer 122 in the storage space 110b from entering the storage space 110a. At least one barrier structure 17 further includes at least one second barrier structure 172. The at least one second barrier structure 172 is installed between the storage space 110a and the vaporization cavity 151 and prevents aerosols in the vaporization cavity 151 from leaking into the storage space 110a. The second barrier structure 172 is a rib installed on the side of the inlet 152 that is close to the storage space 110a, or a constriction structure that narrows the inlet 152. In some embodiments, the blocking structure 17 may be a cap covering the first housing structure 13 and / or the second housing structure 14. The cap is integrally molded with the first housing 11a or the second housing 11b and fits tightly to the first housing 11a or the second housing 11b.
