In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] The aerosol generating device works at a relatively low temperature and performs heating and atomization by heating the aerosol generating matrix at a relatively low temperature. The heating method of the aerosol generating device is usually tubular peripheral heating or central embedded heating. The former refers to the heating tube surrounding the aerosol generating matrix, and the latter refers to the hot heating sheet or heating rod inserted into the aerosol generating matrix. However, the heating efficiency of the above two heating methods is slow, and the fragrance cannot be fully and effectively stimulated, and the user's smoking experience is not good.

[0037] In order to solve the above problems, the embodiment of the present application provides an aerosol generating device 1 and an aerosol generating system, and a heating cup 220 and a heating element 300 are provided at the same time. The heating cup 220 surrounds the periphery of the aerosol generating matrix 2 to heat the outer periphery of the aerosol generating matrix 2, and the heating element 300 is inserted into the center of the aerosol generating matrix 2 to heat the aerosol generating matrix 2, thereby making the heating efficiency of the aerosol generating matrix 2 fast, being able to quickly stimulate the fragrance of the aerosol generating matrix 2, and improving the user's smoking experience.

[0038] See also Figure 1 In a first aspect, an embodiment of the present application provides an aerosol generating system, comprising an aerosol generating substrate 2 and an aerosol generating device 1, wherein the aerosol generating device 1 is used to contain and heat the aerosol generating substrate 2 to generate an aerosol.

[0039] The aerosol-generating matrix 2 may be a solid matrix, for example, one or more of powders, particles, fragments, strips or flakes of one or more plant leaves such as tobacco, herb leaves, tea leaves, mint leaves, etc. Alternatively, the solid matrix may contain additional volatile aroma compounds to be released when the matrix is ​​heated. Of course, the aerosol-generating matrix 2 may also be a liquid matrix or a paste matrix, such as oils or liquid medicines with added aroma components.

[0040] Second, see Figure 2 and Figure 3The embodiment of the present application further provides an aerosol generating device 1, comprising a housing assembly 100, an extractor assembly 200 and a heating element 300. The extractor assembly 200 is installed in the housing assembly 100; the extractor assembly 200 comprises an extractor 210 and a heating cup 220 received in the extractor 210; the heating cup 220 encloses a heating cavity 225 for accommodating an aerosol generating substrate 2, and the heating cup 220 is used to heat the aerosol generating substrate 2; the heating element 300 is at least partially inserted into the heating cavity 225, and the heating element 300 is used to be inserted into the aerosol generating substrate 2 to heat the aerosol generating substrate 2.

[0041] The aerosol generating device 1 provided in the embodiment of the present application, by arranging a heating cup 220 in the extractor assembly 200 to heat the periphery of the aerosol generating matrix 2, and arranging a heating element 300, and inserting the heating element 300 into the aerosol generating matrix 2 to heat the center of the aerosol generating matrix 2, that is, heating is simultaneously performed from the center of the aerosol generating matrix 2 to the outside, and from the periphery of the aerosol generating matrix 2 to the center, thereby improving the heating efficiency of the aerosol generating matrix 2, being able to quickly stimulate the fragrance of the aerosol generating matrix 2 within a short time when the user inhales, and improving the user's inhalation experience.

[0042] In one embodiment, see Figure 2 The extractor assembly 200 is detachably connected to the shell assembly 100, that is, the extractor assembly 200 can be loaded into the shell assembly 100 to accommodate and heat the aerosol generating matrix 2, and the extractor assembly 200 can be separated from the shell assembly 100, so as to facilitate the cleaning of particulate matter dropped into the extractor 210 during the suction process, and at the same time, the heating cup 220 can also be cleaned and maintained to increase the service life of the entire extractor assembly 200.

[0043] See also Figure 2 The housing assembly 100 forms an installation cavity with a top opening. During assembly, the extractor assembly 200 can be inserted into the installation cavity from the top opening. During disassembly, the extractor assembly 200 can be taken out from the top opening.

[0044] In one embodiment, the extractor assembly 200 is installed in the housing assembly 100 by means of a snap fit. In other embodiments, the extractor assembly 200 may also be installed by means of interference fit or fastener locking, which is not the only limitation herein.

[0045] In one embodiment, see Figure 4The extractor 210 is formed with a receiving chamber 213, and the heating cup 220 is received in the receiving chamber 213. The top of the receiving chamber 213 is open, and the aerosol generating substrate 2 has a proximal lip end and a distal lip end that are arranged opposite to each other. The proximal lip end is used for the user to inhale, and the distal lip end of the aerosol generating substrate 2 can be inserted into the heating chamber 225 from the top opening of the extractor 210 until the distal lip end of the aerosol generating substrate 2 abuts against the bottom inner wall of the extractor 210. The heating element 300 is inserted into the distal lip end of the aerosol generating substrate 2 from the bottom of the extractor 210, so that the aerosol generating substrate 2 can be heated.

[0046] In one embodiment, see Figures 3 to 5 The heating cup 220 includes a receiving member 221 and a heating film 222. The receiving member 221 forms a heating cavity 225, and the heating film 222 is arranged on the outer peripheral wall of the receiving member 221. The receiving member 221 forms a heating cavity 225 to accommodate the aerosol generating substrate 2. The receiving member 221 is also used to support the heating film 222 to ensure that the shape of the heating film 222 is stable after assembly and the generated heat is evenly distributed; the heating film 222 is used to generate heat after power is turned on to heat the aerosol generating substrate 2 through the receiving member 221.

[0047] Optionally, the receiving member 221 is a hollow tubular structure. When the aerosol generating matrix 2 is inserted into the heating chamber 225, the receiving member 221 is sleeved outside the aerosol generating matrix 2. The receiving member 221 is made of a metal material, for example, a metal material with high thermal conductivity such as stainless steel or aluminum can be used. It can be understood that in other embodiments of the present application, the receiving member 221 can also be made of an insulating material, for example, a quartz tube, a ceramic tube or a mica tube. In addition, in other embodiments, a radiation layer can also be provided on the inner side wall of the receiving member 221, and the radiation layer is used to radiate infrared rays when heated, so as to use infrared rays to heat and atomize the aerosol generating matrix 2 contained in the receiving member 221. The radiation layer can be formed on the inner side wall of the receiving member 221 by silk screen printing, sputtering, coating, printing, etc. The radiation layer can be specifically an infrared layer, and the material of the infrared layer includes at least one of high infrared emissivity materials such as perovskite system, spinel system, carbide, silicide, nitride, oxide and rare earth system materials.

[0048] In one embodiment, see Figure 4 and Figure 5, the heating film 222 is a heating FPC, the heating FPC is enclosed to form a cylindrical shape and is attached to the outer wall of the receiving piece 221, and a temperature detection circuit is provided on the heating FPC, and the temperature of the heating FPC is detected by the temperature detection circuit, so as to achieve the purpose of temperature control. Specifically, the heating film 222 is fixed to the outer wall of the receiving piece 221 by double-sided tape. In this embodiment, since the surface of the heating FPC is insulated and the double-sided tape is also an insulating member, there is no need to attach an insulating layer between the heating FPC and the receiving piece 221 made of metal. It can be understood that in other embodiments of the present application, the above-mentioned heating film 222 can also be a heating film 222 formed by enclosing a conductive sheet. In this case, an insulating layer needs to be provided between the heating film 222 and the receiving piece 221. Optionally, the heating film 222 is provided on the surface of the receiving piece 221 by a casting process.

[0049] In one embodiment, see Figure 4 and Figure 5 , a heat shrink sleeve 223 is provided on the outer cover of the heating film 222. Among them, since the heating film 222 is adhered to the outer peripheral wall of the receiving piece 221 by double-sided adhesive, when the temperature of the heating film 222 increases, the viscosity of the double-sided adhesive will decrease. In order to prevent the heating film 222 from falling off the receiving piece 221 during the heating process, in this embodiment, a heat shrink sleeve 223 is provided on the outer cover of the heating film 222. The heat shrink sleeve 223 will shrink when heated, so that the heating film 222 can be tightly covered on the receiving piece 221 and will not fall off.

[0050] In one embodiment, see Figure 4 and Figure 5 The heat shrinkable tube 223 is provided with an insulating sleeve 224, which is used to isolate the heat generated by the heating film 222 from the extractor 210, thereby reducing the influence of the heat generated by the heating film 222 on the shell assembly 100 and the power supply assembly 400, and improving the service life of the entire aerosol generating device 1.

[0051] Optionally, the thermal insulation sleeve 224 is an aerogel sleeve. Aerogel is a solid material form, the smallest solid in the world, with high porosity and high thermal insulation performance. It can be understood that in other embodiments of the present application, the thermal insulation sleeve 224 can also be made of other materials, such as thermal insulation foam, which is not limited here.

[0052] In one embodiment, see Figure 4 and Figure 5The extractor 210 includes a plurality of first electrodes 230, each of which is electrically connected to the heating FPC. The aerosol generating device 1 also includes a power supply assembly 400, which includes a plurality of second electrodes 430, each of which is electrically connected to each of the second electrodes 430, so that the heating FPC can be powered by the power supply assembly 400.

[0053] In one embodiment, see Figure 4 and Figure 5 The extractor 210 includes an extraction seat 211 and a bottom cover 212. The extraction seat 211 has a first opening 2111 and a second opening 2112 that are relatively arranged. The bottom cover 212 covers the second opening 2112. A mounting frame 240 is installed at the first opening 2111. The opposite ends of the receiving member 221 are respectively abutted against the bottom cover 212 and the mounting frame 240. With this arrangement, the receiving member 221 can be positioned in the extractor 210 to ensure the installation stability of the receiving member 221 in the extractor 210, and reduce the situation where the aerosol that cannot be sucked in time enters the extractor 210 and produces condensate.

[0054] In one embodiment, see Figure 4 and Figure 5 The mounting frame 240 and the extraction seat 211 are sealed and abutted by a seal 250, which can improve the sealing between the mounting frame 240 and the extraction seat 211, so that the external airflow enters the heating chamber 225 from the mounting frame 240, thereby preventing aerosol from entering the extractor 210.

[0055] For details, please refer to Figure 4 and Figure 5 A limiting ring 2113 extends inward from the first opening 2111 of the extraction seat 211. The mounting frame 240 is a hollow rotating body structure. An annular groove 241 is formed at one end of the mounting frame 240 facing the limiting ring 2113. One side of the sealing member 250 abuts against the limiting ring 2113, and the other side of the sealing member 250 is inserted into the annular groove 241.

The bottom end surface of the receiving piece 221 abuts against the second substrate 2122. The outer peripheral wall of the receiving piece 221 abuts against the inner peripheral wall of the connecting tube 2123, so that the receiving piece 221 can be fixed and limited between the mounting frame 240 and the bottom cover 212.

[0058] In one embodiment, see Figure 5 and Figure 6 A slot 2124 and a hook 2125 are formed on the first substrate 2121, and an insert block 2114 and a slot 2115 are formed at the bottom end of the extraction seat 211. During assembly, the bottom end of the extraction seat 211 is abutted against the first substrate 2121, so that each insert block 2114 is inserted into each slot 2124 one by one, and each slot 2115 is connected to each hook 2125 one by one, thereby realizing the assembly of the extraction seat 211 and the bottom cover 212.
