[0018] In the following description, for the purpose of illustration rather than limitation, specific details of a particular system configuration, technology, etc. are presented in order to thoroughly understand the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention can also be realized in other embodiments without these specific details. In addition, detailed descriptions of known systems, devices, circuits, and methods are omitted so as not to impede the description of the present invention with unnecessary details.

[0019] FIG. 1 shows some preferred embodiments of the aerosol generation system of the present invention. The aerosol generation system 100 can generate an aerosol for a user to inhale. The aerosol generated by the aerosol generation system 100 has the advantages of good texture and high user experience.

[0020] The aerosol generation system 100 includes an aerosol generation matrix assembly 10 and an aerosol generation device 20. The aerosol generation matrix assembly 10 is attached to the aerosol generation device 20 and can generate an aerosol when heated. The aerosol generation matrix assembly 10 can be detachably assembled with the aerosol generation device 20, facilitating the replacement of the aerosol generation matrix assembly 10. The aerosol generation device 20 can atomize the aerosol generation matrix 12 in the aerosol generation matrix assembly 10 by heating it to generate and output an aerosol.

[0021] As shown in FIGS. 2-4, in some embodiments, the aerosol generation matrix assembly 10 includes a box body 11 and an aerosol generation matrix 12. The box body 11 houses the aerosol generation matrix 12. The aerosol generation matrix 12 can be atomized in a heated state to generate an aerosol. In some other embodiments, the box body 11 may be omitted. The aerosol generation matrix 12 may be directly attached to the aerosol generation device 20.

[0022] In some embodiments, the box 11 may be transparent, for example, a transparent plastic box. Of course, in some embodiments, the box 11 is not limited to a transparent structure, but may be opaque, for example, an opaque plastic box or a metal box. In some embodiments, the box 11 may include a first box 11a and a second box 11b, the shape and size of the first box 11a and the second box 11b being approximately the same, and in some embodiments, the first box 11a and the second box 11b being substantially rectangular parallelepipeds. The first box 11a and the second box 11b are not limited to a rectangular parallelepiped shape, but may be, for example, columnar cubes or irregular shapes. Both the first box 11a and the second box 11b have cavities formed inside, and both have an opening structure, and the side of the first box 11a with the side of the second box 11b with the opening can be combined. The first box 11a and the second box 11b can be connected and fixed by providing a connecting structure, which may be a screw assembly, a locking assembly, or other. In some embodiments, the connecting structure may be omitted, and the first box 11a and the second box 11b may be connected using conventional ultrasonic technology.

[0023] As shown in Figures 5-7, in some embodiments, the aerosol generating substrate 12 is strip-shaped overall and is installed in a windable manner. In some embodiments, the aerosol generating substrate 12 includes a base tape 121 and a matrix layer 122, the base tape 121 supporting the matrix layer 122. The matrix layer 122 is formed on the base tape 121, specifically by applying an atomizing medium onto the base tape 121. The atomizing medium may be a liquid-curable atomizing medium, a paste-like atomizing medium, or a solid atomizing medium. In some other embodiments, the matrix layer 122 is not limited to being formed by applying an atomizing medium, but may be formed, for example, by pressing or attaching the atomizing medium to the base tape 121.

[0024] In some embodiments, the base tape 121 is installed longitudinally and has a first surface 121a and a second surface 121b that are arranged facing away from each other, and both the first surface 121a and the second surface 121b may be surfaces defined by the long side and side side of the base tape 121. In this configuration, the first surface 121a can support a matrix layer 122. In some embodiments, the base tape 121 may be a metal sheet made of a material that conducts heat well or has good heat distribution properties, such as aluminum foil or copper foil. Of course, in some other embodiments, the base tape 121 is not limited to a metal sheet, but may be a metal mesh, which may be formed by weaving metal wires or by providing a plurality of through holes in a metal sheet. Of course, the base tape 121 is not limited to metal, but may be made of other materials with high thermal conductivity or high heat distribution properties, such as graphite, silicon carbide, or other surface-treated materials, and this application does not limit this. By manufacturing the base tape 121 from a material with high thermal conductivity or good heat distribution properties, the atomization efficiency of the matrix is ​​higher and heat absorption becomes more uniform.

[0025] Specifically, the matrix layer 122 may be formed on the first surface 121a of the base tape 121, and there may be at least two matrix layers 122, and more specifically, there may be more than two matrix layers 122. The plurality of matrix layers 122 may be spaced apart along the longitudinal direction of the base tape 121. In some embodiments, the plurality of matrix layers 122 may be installed at equal intervals along the length of the base tape 121, i.e., the length of each interval is the same. Each matrix layer 122 may be a substantially rectangular sheet structure. To be understood, in some other embodiments, the matrix layer 122 is not limited to a rectangle, but may be elliptical, circular, etc. In some embodiments, two adjacent matrix layers 122 have the same length extending along the length of the base tape 121, i.e., the length of each matrix layer 122 is the same. By ensuring that two adjacent matrix layers 122 have the same length extending in the longitudinal direction of the base tape 121, and that all matrix layers 122 are installed at equal intervals, the position of the aerosol generating substrate 12 during the transport process becomes easier to determine. In some other embodiments, at least two matrix layers 122 may be distributed at unequal intervals. In some other embodiments, at least two matrix layers 122 may have different lengths extending in the longitudinal direction of the base tape 121. In some embodiments, the thickness of the two adjacent matrix layers 122 may be the same, and the length extending in the width direction of the base tape 121 may also be the same, that is, the maximum amount of aerosol generated when each matrix layer 122 is atomized by heating is the same, and the aerosol can be uniformly drawn in. Naturally, in some other embodiments, the thickness and / or length extending in the width direction of the base tape 121 may be different for two adjacent matrix layers 122.

[0026] In some embodiments, a region on the base tape 121 corresponding to the spacing between two adjacent matrix layers 122 forms a non-atomizing region 1210, i.e., no atomizing medium is applied to this region. In some other embodiments, a region on the base tape 121 corresponding to the spacing between two adjacent matrix layers 122 may be formed by applying a non-atomizing material. The thickness of the applied non-atomizing material may be less than the thickness of the matrix layer 122. By forming the non-atomizing region 1210, the position detection structure 24 in the aerosol generator 20 can more easily determine the position of the aerosol generating substrate 12 based on the mismatch in reflectivity between the matrix layer 122 and the non-atomizing region 1210, and can provide an accurate signal to the feed of the aerosol generating substrate 12.

[0027] In some embodiments, each matrix layer 122 may be configured to be detachable from the base tape 121 after heating. The matrix layer 122 hardens after being heated and atomized, preventing clogging during the transport process of the aerosol generating substrate 12, improving the smoothness of the transport process, and further enhancing the user experience. After the matrix layer 122 is heated and atomized by the heating structure 22, the atomizing medium in the matrix layer 122 hardens after heating, and the adhesive effect between the matrix layer 122 and the base tape 121 decreases. When the matrix layer 122 and the base tape 121 detach during the continuous transport process of the aerosol generating substrate 12, the base tape 121 can avoid clogging and continue to move forward, further enabling the continuous transport of the aerosol generating substrate 12 and resulting in smoother transport. In some embodiments, the heated matrix layer 122 and the base tape 121 may detach automatically or by a separation structure. In some embodiments, the matrix layer 122 may be partially or completely detached from the base tape 121; that is, the matrix layer 122 should be detached from the base tape 121 in such a way that it does not affect the recovery and transport of the aerosol generating substrate 12.

[0028] In some embodiments, the aerosol generating substrate assembly 10 further includes a first housing structure 13. The first housing structure 13 can accommodate an aerosol generating substrate 12 awaiting heating. In some embodiments, the first housing structure 13 is installed inside a box 11. The first housing structure 13 is installable between a first box 11a and a second box 11b and is connected to the first box 11a and the second box 11b. In some embodiments, the first housing structure 13 may be a first storage wheel 131, and the aerosol generating substrate 12 awaiting heating may be wrapped around the first storage wheel 131, which can transport the aerosol generating substrate 12 by rotating. In some embodiments, the first storage wheel 131 includes a first tray 1311 and a second tray 1312, the first tray 1311 and the second tray 1312 may be substantially circular, and their radial dimensions may be substantially the same. The first tray 1311 and the second tray 1312 are connected via a hollow reel, the reel may be formed on the central axis of the first tray 1311 and / or the second tray 1312, or may be independently arranged, and both ends of the reel are connected to the first tray 1311 and the second tray 1312, respectively. The radial dimensions of the reel are smaller than the radial dimensions of the first tray 1311 and the second tray 1312, and the aerosol-generating substrate 12 awaiting heating is wound around the reel. To make it clear, in some other embodiments, the first tray 1311 and the second tray 1312 are not limited to circular shapes but may be rectangular. The first tray 1311 and the second tray 1312 are used to prevent the aerosol generating substrate 12 from escaping during winding. In some embodiments, the first tray 1311 and the second tray 1312 may be omitted. In some embodiments, the first storage wheel 131 is rotatably connected to the first box 11a and / or the second box 11b, and rotation can wind up or unwind the aerosol generating substrate 12 awaiting heating, thereby enabling storage and transport of the aerosol generating substrate 12.

[0029] In some embodiments, the aerosol generating substrate assembly 10 further includes a second housing structure 14 for housing a base tape 121 of the atomized aerosol generating substrate 12, i.e., it can house a base tape 121 from which the matrix layer 122 has been detached. In some embodiments, the second housing structure 14 may include a second housing wheel 141, and the heated base tape 121 may be wound around the second housing wheel 141. In some embodiments, the second housing wheel 141 is provided between a first box 11a and a second box 11b and is connected to the first box 11a and the second box 11b. In some embodiments, the second housing wheel 141 includes a third tray 1411 and a fourth tray 1412. Both the third tray 1411 and the fourth tray 1412 are circular and have substantially equal radial dimensions. The third tray 1411 and the fourth tray 1412 are spaced apart and connected by a hollow reel, which may be formed on the central axis of the third tray 1411 and / or the fourth tray 1412, or may be independently installed, with both ends connected to the third tray 1411 and the fourth tray 1412, respectively. The reel may be cylindrical, with its radial dimension smaller than the radial dimensions of the third tray 1411 and the fourth tray 1412, and the heated base tape 121 may be wound around it. In some embodiments, the third tray 1411 and the fourth tray 1412 are not limited to circular but may be rectangular, and the third tray 141 and the fourth tray 1412 can prevent the base tape 121 from escaping. In some embodiments, the third tray 1411 and the fourth tray 1412 may be omitted. In some embodiments, the second storage wheel 141 is rotatably connected to the first box 11a and / or the second box 11b, and the base tape 121 can be wrapped around it by rotation.

[0030] In some embodiments, the second storage wheel 141 can form a drive wheel, and the first storage wheel 131 can form a driven wheel. Since the base tape 121 is wrapped around the first storage wheel 131 and the second storage wheel 142, the first storage wheel 131 can rotate in conjunction with the second storage wheel 141. When the first storage wheel 131 and the second storage wheel 142 rotate simultaneously, they drive and feed the aerosol generating substrate 12 awaiting heating, and drive the base tape of the atomized aerosol generating substrate 12 to wrap around the second storage wheel 141. In some other embodiments, the second storage wheel 141 is not limited to a drive wheel and may be a driven wheel, and the first storage wheel 131 is not limited to a driven wheel and may be a drive wheel. In some embodiments, the first storage wheel 131 and the second storage wheel 142 may be provided to be independently rotatable, that is, the first storage wheel 131 is rotated by one set of drive structures and the second storage wheel 142 is rotated by another set of drive structures.

[0031] As shown in Figure 8, in some embodiments, the aerosol generating substrate assembly 10 further includes an atomizing shell 15, a portion of which is provided in the box 11. The atomizing shell 15 includes a main body 15a and an extension 15b provided on the main body 15a, the main body 15a can be fitted and attached to the box 11, an atomizing cavity 151 is formed inside the atomizing shell 15, the atomizing shell 15 has an inlet 152 and an outlet 153, the atomizing cavity 151 is formed inside the main body 15a and is defined by a space in which a heating structure 22 heats the aerosol generating substrate 12. The inlet 152 is provided on one side of the main body 15a and communicates with the atomizing cavity 151, and is configured to allow the aerosol generating substrate 12 awaiting heating to enter the atomizing cavity 151. The outlet 153 is provided on the other side of the main body 15a and communicates with the atomizing cavity 151, and is configured to allow the atomized aerosol generating substrate 12 to be discharged. The inlet 152 and outlet 153 are provided opposite each other and are both located on or near the plane in which the center of the atomizing cavity 151 is located. The extension 15b is provided on the main body 15a, extends out from the box 11, and is connected to the mouthpiece assembly 30. The extension 15b is columnar and has a structure in which both ends are through, and an exhaust passage 154 communicating with the atomizing cavity 151 is formed on the inside, and outputs the aerosol formed by atomization. In some other embodiments, the inlet 152 and outlet 153 are not limited to being positioned opposite each other; for example, the inlet 152 and outlet 153 may be located on two adjacent sides of the atomizing cavity 151. In some other embodiments, the atomizing cavity 151 may have only an inlet 152 or only an outlet 153.

[0032] Furthermore, as shown in Figures 5 and 6, in some embodiments, the aerosol generating substrate assembly 10 further includes a guide structure 16 provided in the box 11 for transmitting guides to 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. Here, the first guide roller 161 is installed on one side of the first housing structure 13, and the second guide roller 162 and the third guide roller 163 are installed on two opposing sides of the atomizing shell 15, where 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. The fourth guide roller 164 is located on one side of the second housing structure 14. The connecting wire between the fourth guide roller 164 and the third guide roller 163, and the connecting wire between the second guide roller 162 and the third guide roller 163, are installed to form a predetermined angle greater than 0 degrees and less than 180 degrees. As the first storage wheel 131 and the second storage wheel 141 rotate, the aerosol generating substrate 12 awaiting heating enters the atomizing cavity 151 along the first guide roller 161, the second guide roller 162, and the inlet 152. After atomization, the first storage wheel 131 and the second storage wheel 141 continue to rotate, and the atomized aerosol generating substrate 12 can be output from the outlet 153 and pass through the third guide roller 163. When the atomized aerosol generating substrate 12 passes through the third guide roller 163 and is transmitted to the fourth guide roller 164, it requires rotation, and the heated and atomized matrix layer 122 hardens. If the aerosol generating substrate 12 continues to be transmitted, rotation allows it to detach directly from the base tape 121, i.e., it can even fall off directly. Furthermore, clogging can be avoided when the hardened matrix layer 122 passes through the gap between the third guide roller 163 and the box body 11. Having detached from the matrix layer 122, the base tape 121 continues to be housed in the second storage wheel 141 along the fourth guide roller 164.

[0033] Referring together to Figures 1-3 and 9-10, the aerosol generating device 20 includes a body 21 and a heating structure 22. The body 21 can house an aerosol generating substrate assembly 10. The heating structure 22 is attached to the body 21 and can be inserted into the aerosol generating substrate assembly 10 to heat the aerosol generating substrate 12 in the aerosol generating substrate assembly 10 to generate aerosols.

[0034] In some embodiments, the device 21 includes a housing 211 and a lid 212. The housing 211 includes a first case 211a and a second case 211b. The first case 211a is provided in the second case 211b, and the first case 211a is provided with a storage cavity 2111 for housing an aerosol generating substrate assembly 10. An opening 2112 is provided in the side wall of the first case 211a for mounting the aerosol generating substrate into the storage cavity 2111. The lid 212 is installed in the opening 2112 and is detachably placed over the storage cavity 2111. By opening the lid 212, the aerosol generating substrate assembly 10 can be easily removed and replaced.

[0035] In some embodiments, the heating structure 22 is attached to the first case 211a, located on the bottom wall of the housing cavity 2111, and protruding toward the housing cavity 2111. When the aerosol generating substrate assembly 10 is attached to the housing cavity 2111, the heating structure 22 is inserted into the atomizing shell 15 of the aerosol generating substrate assembly 10 and used to heat the awaiting aerosol generating substrate 12 that has entered the atomizing 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 housing cavity 2111, and the heating element 222 being attached to the base 221. In some embodiments, the heating element 222 may be a metal heating sheet. Naturally, as can be understood, in some other embodiments, the heating element 222 is not limited to a metal heating sheet.

[0036] In some embodiments, the aerosol generator 20 further includes a drive assembly 23, which may be attached to the body 21, specifically, the drive assembly 23 is mounted between a first case 211a and a second case 211b and is partially inserted into a housing cavity 2111 and connected to a second housing structure 14 or a first housing structure 13, and is used to transmit the aerosol generating substrate 12 in the aerosol generating substrate assembly 10 to the heating structure 22. In some embodiments, the drive assembly 23 may be an electrically driven structure, for example, the drive assembly 23 may be a motor or a reduction gear, and the output shaft of the drive assembly 23 may be inserted into the housing cavity 2111 from the side of the first case 211a opposite to the housing cavity 2111 and connected to the second housing structure 14 or the first housing structure 13, that is, connected to the first housing wheel 131 or the second housing wheel 141, and rotate the first housing wheel 131 and the second housing wheel 132. Of course, as can be understood, in some other embodiments, the drive assembly 23 may not be limited to an electrically driven structure, but may be a manual drive structure, for example, a handle or a handwheel.

[0037] In some embodiments, the aerosol generator 20 further includes a position detection structure 24, which is located in the storage cavity 2111 and used to detect the transport position of the aerosol generating substrate 12 and provide feedback to the drive assembly 23, and can further provide accurate signals for the feed and operation of the drive assembly 23 and ensure the motion accuracy of the aerosol generating substrate 12. In some embodiments, the position detection structure 24 may be an infrared detection switch located on the side wall of the storage cavity 2111 and positioned opposite the aerosol generating substrate 12 awaiting heating. When the drive assembly 23 is started, the first storage wheel 131 and the second storage wheel 141 are rotated to further feed the aerosol generating substrate 12 awaiting heating, and when the aerosol generating substrate 12 awaiting heating moves in front of the infrared detection switch, the infrared detection switch can determine the feeding position of the aerosol generating substrate 12 based on the reflectance of the matrix layer 122 and the non-atomizing region 1210. In some other embodiments, the position detection structure 24 is not limited to an infrared detection switch. In some other embodiments, the position detection structure 24 may be a conventional sensor.

[0038] In some embodiments, the aerosol generator 20 further includes a power supply 25, which is located within the housing 211, specifically between a first case 211a and a second case 211b. The power supply 25 supplies power to the drive assembly 23 and the heating structure 22. In some embodiments, the power supply 25 may be a battery.

[0039] In some embodiments, the aerosol generator 20 further includes a main board 26, which is located within the housing 211, specifically between a first case 211a and a second case 211b. The main board 26 is connected to a power supply 25, a drive assembly 23, and a heat generation structure 22. The main board 26 is further connected to a position detection structure 24, which can output start or stop commands to the drive assembly 23 based on the position information of the aerosol generating substrate 12 detected by the position detection structure 24.

[0040] In some embodiments, the aerosol generation system further includes a mouthpiece assembly 30 that can be attached to the atomizing shell 15. Specifically, the mouthpiece assembly 30 is fitted onto the extension 15b and is used by the user to inhale the aerosol output from the atomizing cavity 151.
