[0035] Figure 1The aerosol generating system 100 in some embodiments of the utility model is shown, and the aerosol generating system 100 may include an aerosol generating device 1 and an aerosol generating product 2. The aerosol generating product 2 can be movably plugged into the aerosol generating device 1, so that it is convenient to take out and replace a new aerosol generating product 2 for continued use after heating is completed. The aerosol generating device 1 can bake and heat the aerosol generating product 2 plugged therein after power is turned on, so as to release the aerosol extract in the aerosol generating product 2 without burning.

[0036] In some embodiments, the aerosol generating product 2 may be cylindrical, and of course, in other embodiments, the aerosol generating product 2 may also be in other cylindrical shapes such as elliptical cylinders, polygonal cylinders, etc. The aerosol generating product 2 may include solid materials in the form of strips, sheets, particles, etc. made from leaves and / or stems of plants (such as tobacco or tea leaves), and aroma components may be further added to the solid materials.

[0037] The aerosol generating device 1 may include a housing 40 and a heating component 10, a battery 20 and a circuit board 30 accommodated in the housing 40. The circuit board 30 is electrically connected to the heating component 10 and the battery 20, respectively, and is provided with a relevant control circuit for controlling the power on and off of the heating component 10 by the battery 20. A socket 41 is provided on the top wall of the housing 40, and the aerosol generating product 2 can be at least partially inserted into the housing 40 through the socket 41 for heating. The heating component 10 can be at least partially inserted into the aerosol generating product 2, and the aerosol generating product 2 is heated by radiating infrared light, so that the aerosol generating product 2 generates an aerosol for the user to inhale. The shape of the heating component 10 is not limited, for example, it can be in the shape of a rod or a sheet.

[0038] Figures 2 to 5 The heating component 10 in the first embodiment of the utility model is shown, and the heating component 10 may include a heating structure 19 and a flange 14. The heating structure 19 is fixed in the housing 40 through the flange 14. The heating structure 19 may include a tube body 11 and a heating element 12 at least partially disposed in the tube body 11. The heating element 12 includes a heating body 121, and the heating body 121 can radiate infrared light after being heated. The tube body 11 allows infrared light to pass through, and the tube body 11 is covered outside the heating body 121. The infrared light radiated by the heating body 121 can pass through the tube body 11 into the aerosol generating product 2 to heat the aerosol generating product 2.

[0039] In some embodiments, when powered on, the heating body 121 can quickly heat up to about 1000°C, while the surface temperature of the tube body 11 can be controlled at about 350°C, and the atomization temperature of the aerosol generating product 2 can be controlled at 300°C to 350°C, thereby achieving precise atomization of the aerosol generating product 2 mainly in the infrared light 2μm to 4.75μm band and 8μm to 11μm band.

[0040] In some embodiments, the tube body 11 may be a quartz tube. The tube body 11 can transmit infrared light radiated by the heating element 12, and can also heat the aerosol generating product 2 in contact therewith by heat conduction. The tube body 11 itself can also radiate far infrared after being heated. Of course, in some other embodiments, the tube body 11 is not limited to a quartz tube, and it can also be other light-transmitting materials that can be transmitted by light waves, such as transparent ceramics, diamonds, etc. The tube body 11 and the heating element 12 are at least partially spaced apart, and the tube body 11 and the heating element 12 form an electric heating structure to prevent the heating element 12 from directly contacting the aerosol generating product 2.

[0041] A cavity 110 is formed in the tube body 11 for accommodating at least part of the heating element 12. The tube body 11 has a plug end 114 for inserting into the aerosol generating article 2, and an end of the tube body 11 away from the plug end 114 has a nozzle 113, and the heating element 12 can be loaded into the cavity 110 through the nozzle 113. The cavity 110 can be non-sealed, and when the heating element 12 is installed therein, the cavity 110 does not need to be evacuated or filled with inert gas. Of course, in other embodiments, the cavity 110 can also be sealed, and when the heating element 12 is installed therein, the cavity 110 can be evacuated or filled with inert gas.

[0042] In some embodiments, the tube body 11 may include a main body 111 and a pointed top 112 disposed at one end of the main body 111. The main body 111 may be a hollow circular tube. Of course, in other embodiments, the main body 111 is not limited to a circular tube, and may also be a square tube, an elliptical tube, or a flat tube (sheet) or other shapes.

[0043] The pointed top portion 112 is disposed at one end of the main body 111 away from the nozzle 113. The pointed top portion 112 may be tapered, and its outer diameter gradually decreases in the direction away from the main body 111. The heating component 10 may be conveniently inserted into the aerosol generating product 2 through the pointed top portion 112. The pointed top portion 112 may be integrally formed with the main body 111. Of course, in other embodiments, the pointed top portion 112 and the main body 111 may also be formed separately and then assembled together.

[0044] The heating element 12 may include a heating body 121 and a first electrode lead 122 and a second electrode lead 123 respectively connected to the two electrodes of the heating body 121. The outer surface of the heating body 121 is at least partially spaced apart from the inner surface of the tube body 11. In some embodiments, the entire outer surface of the heating body 121 is spaced apart from the inner surface of the tube body 11, and can radiate infrared light in the energized state, and the infrared light can pass through the tube body 11 to the aerosol generating article 2. In other embodiments, the outer surface of the heating body 121 and the inner surface of the tube body 11 may also be partially in contact and partially spaced apart.

[0045] The heating body 121 may include a heating substrate and a heat radiation layer disposed on the heating substrate. The heating substrate may generate heat when powered on. The heating substrate may be a heating wire or a heating sheet, which may be made of metal materials such as nickel-chromium alloy (such as nickel-chromium alloy wire), iron-chromium-aluminum alloy (such as iron-chromium-aluminum alloy wire) and the like having good high-temperature oxidation resistance, high stability, and not easy to deform. The heat radiation layer may be an infrared layer, which may be formed on the heating substrate under high-temperature heat treatment and may radiate infrared light after being heated. In some embodiments, the heating body 121 may further include an anti-oxidation layer disposed between the heating substrate and the heat radiation layer. In some embodiments, the heating substrate is subjected to high-temperature heat treatment and a dense oxide film is generated on its own surface, and the oxide film may form an anti-oxidation layer.

[0046] In some embodiments, the heating body 121 has a longitudinal structure, such as a hollow spiral structure, which can be wound or assembled by at least one heating wire. Of course, in other embodiments, the spiral structure can also be formed by etching on the heating tube. The outer surface of the heating wire can be provided with an infrared layer, and the heating wire is electrically heated, and the infrared layer radiates infrared light after being heated. The heating wire can be a round wire. Of course, in other embodiments, the heating wire is not limited to a round wire.

[0047] In some embodiments, the heating body 121 may have a single spiral structure formed by winding a monofilament, which may include a central rod 1212 and a spiral portion 1211 wound outside the central rod 1212. The central rod 1212 may be a straight rod, which may be coaxially arranged with the spiral portion 1211 and the tube body 11, but is not limited to a coaxial arrangement. The two free ends of the spiral portion 1211 are respectively located at two opposite ends of the axial direction. One end of the central rod 1212 facing the tip 112 (the upper end is shown in the figure) is connected to one end of the spiral portion 1211 facing the tip 112. One end of the central rod 1212 away from the tip 112 (the lower end is shown in the figure) can be passed through the spiral portion 1211, which is convenient for welding and connection with the first electrode lead 122. The second electrode lead 123 is welded and connected to one end of the spiral portion 1211 away from the tip 112. In this way, the first electrode lead 122 and the second electrode lead 123 are both led out from the lower end of the heating body 121, and the lead-out and welding operations are more convenient.

[0048] In other embodiments, the spiral portion 1211 of the heating body 121 may also have a hollow double helix structure. Here, the double helix structure refers to a structure having two spiral lines in parallel, which can be formed by folding a single heating wire in half and then winding it in two strands. The two free ends of the spiral portion 1211 are both located at the same axial end, that is, both are located at the lower end or the upper end of the heating body 121. Preferably, the two free ends of the spiral portion 1211 are both located at the lower end of the heating body 121, which is convenient for leading out the electrode lead. In this way, the heating body 121 may not have a center rod.

[0049] In some embodiments, the spirals of the spiral portion 1211 may be distributed at equal intervals. Of course, in other embodiments, the spirals of the spiral portion 1211 may be arranged to be distributed at non-equal intervals according to the temperature field distribution requirements. For example, the interval between the spirals of the spiral portion 1211 may gradually increase or decrease from bottom to top, or the interval between the spirals of the spiral portion 1211 at its two end portions may be smaller or larger than the interval between the spirals in its middle portion.

[0050] In some embodiments, the heating component 10 may further include a temperature measuring element 15 for monitoring the temperature in the tube body 11. The temperature measuring element 15 may be a thermocouple, which may include a temperature measuring probe 151 and two temperature measuring leads 152 connected to the temperature measuring probe 151. The temperature measuring probe 151 is disposed in the tube body 11 and may be disposed in contact with the inner wall of the tube body 11.

[0051] In some embodiments, the heating structure 19 may further include a support member 13, which is at least partially installed in the tube body 11 and supports the heating element 12 and the temperature measuring element 15. The support member 13 may be columnar, and it may be located below the spiral portion 1211 in the axial direction. The first electrode lead 122 and / or the second electrode lead 123 and / or the temperature measuring element 15 may pass through the support member 13 or be arranged between the support member 13 and the tube body 11. The end of the support member 13 away from the plug-in end 114 has a support member end face 138, and the electrical leads 190 (including the first electrode lead 122, the second electrode lead 123 and the two temperature measuring leads 152) may pass through the support member end face 138, which is convenient for connection with an external control circuit.

[0052] The support member 13 can be made of insulating materials such as ceramic, quartz or high-temperature resistant plastic, and can be used to insulate and separate the first electrode lead 122 , the second electrode lead 123 and the two temperature measurement leads 152 .

[0053] In some embodiments, at least one channel 130 may be provided on the support member 13 for the first electrode lead 122 and / or the second electrode lead 123 and / or the temperature measuring element 15 to pass through. The at least one channel 130 may be provided on the outer surface of the support member 13 and / or be provided through the support member 13, and may extend along the axial direction of the support member 13.

[0054] In some embodiments, the at least one channel 130 may include a first channel 131, a second channel 132, and a third channel 133. The first channel 131 may axially penetrate both ends of the support member 13 and may be coaxially arranged with the support member 13. The second channel 132 and the third channel 133 may be arranged on the outer surface of the support member 13 and may be respectively located on two opposite radial sides of the support member 13. The first channel 131 and the second channel 132 may respectively allow the first electrode lead 122 and the second electrode lead 123 to pass through. The third channel 133 may be used for the temperature measuring element 15 to pass through. In order to further improve the fixing effect, the electric lead 190 and the support member 13 may be bonded and fixed by using an adhesive to prevent the electric lead 190 from shifting due to pulling during the assembly process.

[0055] Of course, in other embodiments, the first electrode lead 122 and / or the second electrode lead 123 and / or the temperature measuring element 15 can also be directly bonded and fixed to the outer surface of the support member 13 by means of gluing or the like, so that the first channel 131 and / or the second channel 132 and / or the third channel 133 can also be omitted.

[0056] In some embodiments, a partition portion 135 is provided on the support member 13 . The partition portion 135 is protruding from the upper end surface of the support member 13 and is located between the third channel 133 and the first channel 131 , and is used to separate the temperature measuring element 15 and the first electrode lead 122 .

[0057] In some embodiments, a partition 134 may also be provided in the third channel 133 to separate the two temperature measuring leads 152. In some embodiments, the partition 134 may be provided at the upper portion of the third channel 133 and may extend out of the upper end surface of the third channel 133. Of course, in other embodiments, the partition 135 and / or the partition 134 may also be omitted.

[0058] The flange 14 can be sleeved on one end (shown as the lower end) of the tube body 11 away from the pointed top 112, and is used to support the tube body 11 and the support member 13. A connecting hole 140 is formed through the flange 14, and a step surface 143 is formed on the inner side of the connecting hole 140. The lower end of the tube body 11 can be received in the connecting hole 140 and can be against the step surface 143. In some embodiments, the connecting hole 140 may include a first hole portion 141 located on the upper side and a second hole portion 142 located on the lower side. The aperture of the first hole portion 141 may be larger than the aperture of the second hole portion 142, so that a step surface 143 is formed at the intersection of the first hole portion 141 and the second hole portion 142.

[0059] In some embodiments, a sealing structure 16 may be provided between the tube body 11 and the flange 14. The sealing structure 16 is at least partially provided between the outer wall surface of the lower end of the tube body 11 and the inner wall surface of the first hole portion 141, and can prevent liquid (e.g., condensate) from contaminating components such as the battery downward. The sealing structure 16 may include an adhesive and / or a sealing ring. The sealing ring may be made of a sealing material such as silicone, and the tube body 11 may be interference-fitted with the flange 14 through the sealing ring, thereby improving the sealing between the tube body 11 and the flange 14 and making the fixation between the tube body 11 and the flange 14 more secure. The adhesive may be, but is not limited to, a curing agent such as resin, inorganic glue, or organic glue. The adhesive can bond the tube body 11 and the flange 14 together, and play a role in fixing and sealing. The tube body 11 is fixed to the flange 14 through the adhesive, and then fixed in the housing 40 through the flange 14, thereby preventing the displacement of the heating structure 19 due to the insertion and removal of the aerosol generating product 2.

[0060] The support member 13 partially extends into the tube body 11 and partially penetrates the flange 14. The end of the support member 13 away from the pointed top 112 has a support member end face 138, and the end of the flange 14 away from the pointed top 112 has a flange end face 1420. The support member end face 138 can be flush with the flange end face 1420, or the support member end face 138 can also extend out of the flange end face 1420. A gap is left between the support member 13 and at least part of the inner wall of the second hole portion 142. The gap should not be too large, otherwise it is not conducive to the positioning of the support member 13 in the flange 14. In some embodiments, the gap can be less than or equal to 0.2 mm.

[0061] In some embodiments, a bonding structure 17 may be formed on the flange end face 1420 by dispensing glue or the like to fix the flange 14 and the support member 13. In this embodiment, bonding and fixing are performed on the flange end face 1420, and grouting into the connection hole 140 is not required, so the bonding operation is easier and the assembly efficiency is higher. The colloid of the bonding structure 17 may be, but is not limited to, a curing agent such as resin, inorganic glue, and organic glue. In addition, the colloid enters as little as possible between the fixed flange 14 and the support member 13, and the negative effects caused by the thermal expansion and contraction of the colloid can also be avoided.

[0062] The bonding structure 17 can also bond the electrical lead 190 to the support 13 to prevent the electrical lead 190 from shifting due to pulling during assembly. Of course, the bonding operation can also be performed on the support 13 alone, that is, a bonding structure is additionally provided on the support 13 to bond the electrical lead 190 to the support 13.

[0063] In some embodiments, at least one slot 1421 is provided on the side wall of the flange 14 through the inner and outer sides thereof, and glue can be applied in the slot 1421 to further fix the flange 14 and the support member 13. Specifically, the at least one slot 1421 can penetrate the flange end surface 1420, and can penetrate the inner and outer sides of the flange 14 to communicate with the second hole portion 142. The bonding structure 17 is partially disposed in the at least one slot 1421, and can be bonded to the support member 13 through the slot 1421 to increase the anchoring force between the bonding structure 17 and the flange 14 and the support member 13. The number of slots 1421 is not limited, for example, there can be one slot 1421 and it can be disposed on the side wall of the second hole portion 142, or there can be multiple slots 1421 and they can be arranged at intervals along the circumferential direction on the side wall of the second hole portion 142. When there are multiple slots 1421, the shapes and / or sizes of the multiple slots 1421 can be the same or different.

[0064] In addition, at least one notch 136 may be provided on the side wall of the support member 13, and the notch 136 may be connected to the flange end face 1420, so that part of the glue can flow into the notch 136 when the flange end face 1420 is glued, so as to further anchor the support member 13 and the flange 14. Specifically, the notch 136 may be formed by a depression on the outer surface of the support member 13, and may penetrate the support member end face 138. Of course, when the support member end face 138 extends out of the flange end face 1420, the notch 136 may not penetrate the support member end face 138. In this embodiment, there are two notches 136, and the two notches 136 are respectively formed by a part of the second channel 132 and the third channel 133 away from the plug end 114, so that the number of slots on the support member 13 can be reduced, and the electrical lead 190 can also be bonded and fixed to the support member 13. Of course, in other embodiments, the notch 136 may also be provided independently.

[0065] like Figure 6 As shown, in some embodiments, at least one convex-concave structure 1422 may be provided on the flange end face 1420, and the bonding structure 17 may be at least partially provided on at least one convex-concave structure 1422, so that the anchoring force between the colloid and the flange 14 and the support member 13 can be increased during dispensing. Specifically, the convex-concave structure 1422 may be a protrusion formed by protruding on the flange end face 1420; or, the convex-concave structure 1422 may also be a groove formed by being recessed on the flange end face 1420, and the groove may not be connected to the connecting hole 140. The number of the convex-concave structures 1422 is not limited, and it may be one or more. When there are multiple convex-concave structures 1422, the multiple convex-concave structures 1422 may be arranged at intervals in the circumferential direction of the flange end face 1420. In addition, the multiple convex-concave structures 1422 may all be protrusions or grooves; or, the multiple convex-concave structures 1422 may also be partially convex and partially grooves, and further, the protrusions and grooves may be distributed alternately.

[0066] Figure 7 , Figure 8 The heating component 10 in the second embodiment of the utility model is shown. The main difference between the second embodiment and the first embodiment is that in the second embodiment, a limiting protrusion 137 is formed on the lower side wall of the support member 13, and a limiting groove 1423 matching the limiting protrusion 137 is correspondingly provided on the side wall of the flange 14. During assembly, the limiting protrusion 137 is engaged with the limiting groove 1423 and then fixed by glue on the flange end face 1420. The limiting protrusion 137 can effectively prevent the support member 13 from rotating due to the pulling of the lead wire during the assembly process, thereby affecting the assembly accuracy and efficiency.

[0067] The number of the limiting grooves 1423 and the limiting protrusions 137 is not limited, and can be one or more. The limiting grooves 1423 can extend upward from the flange end surface 1420, which can facilitate the limiting protrusions 137 to enter the limiting grooves 1423 from the lower opening on the one hand, and on the other hand, part of the glue can flow into the limiting grooves 1423 during glue dispensing to further anchor the support member 13 and the flange 14.

[0068] It can be understood that the above-mentioned technical features can be used in any combination without limitation.

[0069] The above embodiments only express the specific implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
