[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] like Figure 1 Paper Figure 3 As shown, an embodiment of the present invention provides an aerosol generating system, comprising: The heating module 100 includes a housing 110 having a receiving space 120 and a light heating assembly 130 mounted on the housing 110 .

[0027] The aerosol generating module 200 comprises a light-transmitting package body 210 and an aerosol substrate 230 encapsulated in the light-transmitting package body 210; the aerosol generating module 200 is detachably installed in the accommodating space 120; the light-transmitting package body 210 is provided with at least one air hole 211 communicating with the accommodating space 120; The optical heating assembly 130 is axially spaced from the light-transmitting encapsulating body 210 ; the light emitted by the optical heating assembly 130 penetrates the light-transmitting encapsulating body 210 and irradiates the aerosol substrate 230 to heat the aerosol substrate 230 to generate aerosol.

[0028] Specifically, the optical heating assembly 130 is disposed opposite to the light-transmitting package body 210. Meanwhile, the optical heating assembly 130 is not located in the axial direction of the light-transmitting package body 210, and is spaced apart from the light-transmitting package body 210 in the axial direction; for example, Figure 1 As shown, the light-transmitting package body 210 is in a capsule shape, and at this time, the optical heating component 130 is spaced apart from the central axis of the light-transmitting package body 210 .

[0029] In this embodiment, a containing space 220 is provided on the light-transmitting package 210 for packaging an aerosol matrix 230. The light emitted by the light heating component 130 can penetrate the light-transmitting package 210 and directly irradiate the aerosol matrix 230. Through this light heating method, the aerosol matrix 230 is heated and then generates an aerosol. The aerosol overflows from the containing space 220 through the air holes 211 and enters the containing space 120. Through the precise matching of the light heating component 130 and the light-transmitting package 210, and the heating conversion of the aerosol matrix under specific conditions, the effective generation and release of the aerosol is achieved.

[0030] In this embodiment, the optical heating assembly 130 is fixedly mounted on the housing 110 and is located in the accommodation space 120. Specifically, the inner wall of the accommodation space 120 is recessed to form an installation groove, and the optical heating assembly 130 is installed in the installation groove of the accommodation space 120.

[0031] Furthermore, the optical heating component 130 can emit infrared light, which has a strong thermal effect and can be used to heat objects. When the optical heating component 130 emits infrared light of a specific wavelength to irradiate the aerosol matrix 230, since the infrared light has good penetrating power, it can penetrate the surface of the aerosol matrix 230, causing the molecules and atoms inside the aerosol matrix 230 to resonate and generate strong vibration and rotation. The vibration and rotation of these molecules and atoms increase the thermal motion energy, thereby increasing the temperature of the aerosol matrix 230 and achieving the purpose of heating. In this process, the infrared radiation energy emitted by the optical heating component 130 is absorbed by the aerosol matrix 230 and converted into heat energy, so that the inside and surface of the matrix are heated at the same time. This method is not only efficient, but also can achieve uniform heating and avoid the problem of local overheating. In addition, since infrared heating is a non-contact heating, it does not need to be transmitted through a heat transfer medium, but uses the high transmittance of the light-transmitting package 210 to directly heat the aerosol matrix 230 through the light-transmitting package 210. This method has high thermal efficiency and can quickly reach the required heating temperature while reducing energy loss.

[0032] In one embodiment, the material of the light-transmitting package 210 includes but is not limited to containing high molecular polymers, polymethyl methacrylate or polycarbonate. For example, the light-transmitting package 210 can be glass. In one embodiment, the material of the light-transmitting package 210 also contains gelatin, modified cellulose, modified starch, alginate or 2%-8% nanocrystalline material, and the nanocrystalline material is nanocrystalline ceramic or nanocrystalline glass. The above-mentioned high-transparency polymethyl methacrylate or polycarbonate is used as the material of the light-transmitting package 210. These materials not only have good infrared light transmittance, but also have excellent heat resistance and chemical stability. Therefore, they will not produce odors such as those generated when materials such as cigarette paper are heated or burned. This odor will affect the tobacco flavor of the aerosol and thus affect the experience. Further, the light transmittance of the light-transmitting package 210 should be greater than 80% to ensure that the infrared light emitted by the light heating component 130 can effectively penetrate the light-transmitting package 210 and heat the internal aerosol matrix 230. High transmittance materials allow infrared light to directly act on the aerosol matrix, improving heating efficiency, quickly reaching the required heating temperature, and reducing energy loss. In one embodiment, the length of the light-transmitting package 210 is 8-15 mm, preferably 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm; the widest width of the light-transmitting package 210 is 5-10 mm, preferably 6 mm, 7 mm, 8 mm, 9 mm. The shape of the light-transmitting package 210 can be set according to demand, for example, the light-transmitting package 210 can be set to be capsule-shaped, rectangular, multi-prism-shaped, cylindrical or even irregular. The storage space 220 of the light-transmitting package 210 contains tobacco and can be detachably installed in the storage space 120.

[0033] In one embodiment, the aerosol generating module 200 has a suction resistance of 150-700 mm H2O. Within the above suction resistance range, the user has a better inhalation experience of the aerosol generating system.

[0034] Among them, the aerosol matrix 230 can release volatile compounds when heated, and these volatile compounds can form an aerosol with tobacco flavor. In this embodiment, the aerosol can be visible or invisible, and can include vapor (for example, gas including fine particles of a substance, which are usually in a liquid or solid state at room temperature), and droplets of gas and condensed vapor, etc. In some embodiments, the aerosol matrix 230 can include one or more of the following states: powder, granules, floccules, strips, sheets, pellets, fragments, etc., and the aerosol matrix 230 contains one or more of the following substances: dried flowers or fragrant leaves, grass leaves, tobacco leaves, tobacco main veins, expanded tobacco and homogenized tobacco, etc. In this embodiment, one or more aerosol matrices 230 can be contained in the containing space 220.

[0035] In one embodiment, the ratio between the volume of the space inside the light-transmitting package 210 and the volume of the aerosol matrix 230 is 1:A; wherein the volume of the space inside the light-transmitting package 210 is the volume of the containing space 220 of the light-transmitting package 210. The value range of A is 0.3-0.8, and preferably the value range of A is 0.4-0.6, 0.5-0.7. This means that in the containing space 220, the aerosol matrix 230 only occupies part of the volume of the containing space 220, and the remaining space volume serves as a gap for the flow of gas or aerosol generated after heating, thereby improving the generation and flow efficiency of aerosol. Preferably, the porosity of the aerosol matrix 230 is 30%-70%, and preferably the porosity is 40%-60%, 50%-55%. The porosity between the aerosol matrix 230 contained in the containing space 220 of the light-transmitting package 210 is 30%-70%. In another embodiment, the porosity of the aerosol generating module 200 is 30%-70%, that is, after the aerosol matrix 230 is completely contained in the light-transmitting package 210, the porosity of the combination of the light-transmitting package 210 and the aerosol matrix 230 is set to be 30%-70%. This specific porosity ensures that there is enough space between the aerosol matrix 230 in the containing space 220 of the light-transmitting package 210 to allow the gas or the aerosol generated after heating to flow, thereby improving the efficiency of aerosol generation and flow. This design not only ensures that the aerosol matrix 230 can effectively release volatile compounds when heated to form an aerosol with tobacco flavor, but also ensures the performance of the aerosol generating module 200 in terms of suction experience and heating efficiency. By maintaining an appropriate porosity, the stability and uniformity of the aerosol matrix 230 during the heating process can be guaranteed to the greatest extent, avoiding the influence of the aerosol generation quality due to excessively high or low porosity.

[0036] In one embodiment, the aperture of the air hole 211 is smaller than the minimum projection area of ​​the aerosol matrix 230. It is understandable that the minimum projection area of ​​the aerosol matrix 230 refers to the minimum area of ​​the projection surface of the aerosol matrix 230 on all different planes; since the minimum projection area is also larger than the aperture of the air hole 211, the aerosol matrix 230 contained in the containing space 220 will not leak out from the air hole 211 in any direction. The cleanliness of the containing space 120 is ensured, and the waste of the aerosol matrix 230 is avoided. Further, the minimum projection area of ​​the aerosol matrix 230 is 10%-20% larger than the aperture of the air hole 211. It is understandable that the number and installation position of the air hole 211 can be set according to the needs, only one air hole 211 can be set, and multiple air holes 211 can be set at intervals. The arrangement shape can also be set according to actual needs, and it is not limited again.

[0037] In one embodiment, if Figure 1 and Figure 3 As shown, the housing 110 is provided with an air inlet 111 and an air outlet 112 connected to the accommodation space 120; a first airflow channel is formed between the air inlet 111, the accommodation space 120 and the air outlet 112, and the first airflow channel allows external airflow to enter the accommodation space 120 through the air inlet 111, so as to drive the aerosol overflowing from the air vent 211 to flow out from the air outlet 112. The air inlet 111 and the air outlet 112 are holes, through grooves or gaps provided on the housing 110, so that the accommodation space 120 can be connected to the outside atmosphere. Specifically, after the light heating component 130 heats the aerosol matrix 230 to generate aerosol, the aerosol enters the containing space 120 through the air vent 211. When suction is generated at the air outlet 112, the outside air inlet 111 enters the containing space 120 and carries the aerosol out from the air outlet 112, completing the output flow path of the aerosol in the air flow channel.

[0038] In one embodiment, if Figure 1 and Figure 3 As shown, the air holes 211 include a first air hole 2111 connected to the air inlet 111, and a second air hole 2112 connected to the air outlet 112; a second air flow channel is formed between the air inlet 111, the first air hole 2111, the containing space 220, the second air hole 2112, and the air outlet 112. The external air flow enters the light-transmitting package 210 through the air inlet 111 and the first air hole 2111 in sequence, so as to push the aerosol generated by light heating to overflow to the air outlet 112 through the second air hole 2112. In this embodiment, the first air hole 2111 and the second air hole 2112 are respectively arranged at the side ends of the light-transmitting package 210. It can be understood that the first air hole or the second air hole can be respectively arranged at the upper and lower ends of the light-transmitting package 210 of a capsule-like shape.

[0039] In this embodiment, the air holes 211 include a first air hole 2111 and a second air hole 2112. After the light heating component 130 heats the aerosol substrate 230 to generate aerosol, if the air outlet 112 does not generate suction, the aerosol will enter the accommodation space 120 through the first air hole 2111 and the second air hole 2112; and when the air outlet 112 generates suction, the outside air enters the light-transmitting package 210 through the air inlet 111 and the first air hole 2111, and the aerosol is driven by the entering gas to be output from the second air hole 2112 to the air outlet 112. That is, the air may be output to the air outlet 112 through the accommodation space 120 or directly output to the air outlet 112.

[0040] It should be noted that in this embodiment, the first airflow channel and the second airflow channel are both aerosol circulation channels. The air entering from the air inlet 111 can carry aerosol through the first airflow channel and the second airflow channel respectively and be output from the air outlet 112, thereby improving the aerosol output efficiency.

[0041] In one embodiment, the aerosol generating system further includes a filter 113 for filtering aerosols, and the filter 113 is arranged longitudinally with the shell 110. The filter nozzle 113 includes but is not limited to a porous material, such as cellulose acetate. The filter nozzle 113 is exposed on the shell 110, which is convenient for the user to perform a suction action and generate suction at the air outlet 112. It can be understood that the shell 110 is composed of a sealing member 114 and a heating section, wherein the optical heating assembly 130 is arranged on the heating section, and the sealing section is used to connect the heating section and the filter nozzle 113, and the heating section, the sealing section and the filter nozzle 113 are detachably connected to facilitate cleaning of the residue in the accommodating space 120.

[0042] In one embodiment, if Figure 1 As shown, a hatch 115 is also provided on the shell 110, and the hatch 115 is connected to the accommodating space 120 for conveniently taking and placing the aerosol generating module 200. The hatch 115 is provided with a hatch door 140, and the hatch door 140 is used to open or close the accommodating space 120, so as to facilitate the removal and installation of the aerosol generating module 200. The size of the hatch 115 is larger than the light-transmitting package 210, ensuring that the aerosol generating module 200 can be smoothly loaded and unloaded through the hatch 115. When the aerosol generating module 200 needs to be installed or removed, the hatch door 140 is opened, and after the operation is completed, the hatch door 140 is closed again to protect the components inside the shell 110 from damage or contamination. Such a design not only facilitates the maintenance of the aerosol generating module 200, but also ensures the sealing and safety of the equipment.

[0043] In one embodiment, if Figure 1 and Figure 3 As shown, the heating module 100 further includes a stopper 150 mounted on the hatch 140 and extending into the accommodation space 120, and the aerosol generating module 200 is mounted on the stopper 150. The aerosol generating module 200 is stably mounted in the accommodation space 120 by the stopper 150. The stopper 150 is mounted on the hatch 140. When the hatch 140 is opened and leaves the hatch 115, the stopper 150 can be transferred out of the accommodation space 120 with the hatch 140, so as to facilitate the installation of the aerosol generating module 200; when the hatch 140 is closed, the aerosol generating module 200 and the stopper 150 enter the accommodation space 120 together.

[0044] It is understandable that in some embodiments, the position of the stopper 150 opposite to the optical heating assembly 130 is provided with an irradiation through hole 1521, so that the light emitted by the optical heating assembly 130 is directly irradiated on the light-transmitting package 210 through the irradiation through hole 1521, and irradiated on the aerosol substrate 230 through the light-transmitting package 210. In other embodiments, the stopper 150 is a stopper bar or a stopper rib, and the stopper 150 blocks the light emitted by the optical heating assembly 130 as little as possible. In a preferred embodiment, the stopper 150 is made of a transparent material with high transmittance, so as to avoid blocking the light emitted by the optical heating assembly 130, thereby improving the heating efficiency. It should be noted that a through hole 1521 connected to the air inlet 111 may also be provided on the limiting member 150, so that the air inlet 111 is connected to the first air hole 2111 through the through hole 1521, so that the gas entering the air inlet 111 can enter the containing space 220 through the through hole 1521 and the first air hole 2111, and be output from the second air hole 2112 and the air outlet 112 with the entrained aerosol.

[0045] In one embodiment, if Figure 1 and Figure 3 As shown, the stopper 150 includes a bottom support member 152 connected to the hatch 140 and a side support member 151 installed on the bottom support member 152, and the two together form an installation cavity for installing the aerosol generating module 200. In this embodiment, the side support member 151 and the bottom support member 152 can be composed of a support rod or a support plate, etc., and an installation cavity for accommodating or clamping the aerosol generating module 200 is formed between the side support member 151 and the bottom support member 152 to ensure stable installation of the aerosol generating module 200. In addition, in order not to hinder the light emitted by the optical heating component 130, the bottom support member 152 and the side support member 151 can be made of transparent materials. Such a design not only ensures the stability of the structure, but also improves the heating efficiency.

[0046] In one embodiment, if Figure 1 and Figure 3 As shown, the light heating assembly 130 includes at least one light emitting element 131 disposed in the accommodating space 120, and the light emitting element 131 is axially spaced from the light transmissive package 210. Understandably, the light emitting element 131 may be a lamp bead, such as a bar or spherical lamp bead. The number, size, and arrangement position of the light emitting element 131 may be set as required. The light emitted by the light emitting element 131 will irradiate the aerosol substrate 230 through the light transmissive package 210 to heat it, so as to generate an aerosol output through the air permeable hole 211.

[0047] In one embodiment, if Figure 1As shown, the optical heating assembly 130 includes a plurality of the light emitting elements 131, and the plurality of the light emitting elements 131 are arranged around the light-transmitting package 210; in one aspect of this embodiment, the plurality of the light emitting elements 131 are arranged at intervals on the inner side wall of the accommodation space 120; specifically, the light emitting element 131 can be directly mounted on the inner side wall of the accommodation space 120 of the housing 110, for example, a snap-in groove adapted to the light emitting element 131 can be arranged on the inner side wall of the accommodation space 120 of the housing 110, and then the light emitting element 131 is directly snap-into the snap-in groove, or the light emitting element 131 is fixed to the inner side wall of the accommodation space 120 by other fixing members. In another aspect of this embodiment, the optical heating assembly 130 includes a mounting sheet 132 arranged around the light-transmitting package 210, and the plurality of the light emitting elements 131 are mounted at intervals on the mounting sheet 132, and the light emitting elements 131 face the light-transmitting package 210. In this embodiment, a mounting sheet 132 arranged around the light-transmitting package 210 can be installed in the accommodation space 120, and all the light-emitting elements 131 can be installed by using the mounting sheet 132, so that all the light-emitting elements 131 are arranged at intervals around the light-transmitting package 210.
