For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0036] Figure 1 and Figure 2 The first embodiment of the aerosol-generating device of the present invention is shown. This aerosol-generating device heats the aerosol-generating substrate using a heat-without-combustion method. Specifically, the aerosol-generating device heats the aerosol-generating substrate via infrared radiation. In this embodiment, the aerosol-generating substrate can be columnar, and can be a solid material in the form of strips, sheets, granules, or integral moldings made from leaves and / or stems of plants (e.g., tobacco). Fragrance components can also be added to this solid material.

[0037] In this embodiment, the aerosol generating device may include a housing 10, a fixing component 20, and a heating component 30. The housing 10 is used to accommodate the fixing component 20, and the fixing component 20 can be used to fix the heating component 30. The heating component 30 is arranged in the fixing component 20 and is then fixed in the housing 10 through the fixing component 20. The heating component 30 can be sleeved on the periphery of the aerosol generating matrix, and can heat the aerosol generating matrix by heat conduction and / or radiation of infrared light waves, so that the aerosol generating matrix generates an aerosol for the user to inhale. In this embodiment, the aerosol generating device may also include a power supply component, which can be connected to the heating component 30 to supply power to the heating component 30.

[0038] In this embodiment, the housing 10 is generally cylindrical and may include a shell 10a and a cover 10b. The shell 10a has a hollow structure with an assembly opening, and the cover 10b is configured to cover the assembly opening. The cover 10b may have an insertion port 11 for inserting the aerosol generating substrate into the heating element 30.

[0039] like Figures 3 to 5As shown, in the present embodiment, the fixing assembly 20 may include a fixing base 21 and a fixing sleeve 22. The fixing base 21 is used to fix the heating assembly 30. The heating assembly 30 may be arranged in the fixing base 21 and fixedly matched with the fixing base 21. A fixing groove 210 is provided on the inner side of the fixing base 21, and the fixing groove 210 can be used for inserting the heating assembly 30. In some other embodiments, it may not be limited to being fixed with the fixing base 21 by interference fit, but may also be fixed by screwing. An air flow channel 211 may be connected to the fixing base 21, and the air flow channel 211 may extend along the axial direction of the fixing base 21, and then bend to communicate with the outside. External gas may enter the heating assembly 30 through the air flow channel 211 and bring out the aerosol generated by the aerosol generating matrix. The fixing sleeve 22 is sleeved on the fixing base 21 and on the outer periphery of the heating component 30. It can be coaxially arranged with the fixing base 21, and the inner side is a hollow structure. An opening 221 is provided at one end away from the fixing base 21, which is coaxial with and connected to the plug-in port 11. At least part of the aerosol generating matrix can be inserted into the heating component 30 through the plug-in port 11 and then through the opening 221.

[0040] In this embodiment, the fixing assembly 20 further includes a first end wall 20a and a second end wall 20b; the first end wall 20a and the second end wall 20b are arranged opposite each other along the axial direction of the fixing assembly 20. Specifically, the first end wall 20a can be formed in the fixing seat 21, and more specifically, the first end wall is formed in the fixing groove 210, which can be formed by the bottom wall of the fixing groove 210. The second end wall 20b is formed on the fixing sleeve 22 and is arranged toward the fixing groove 210.

[0041] like Figure 6As shown, in this embodiment, the heating component 30 is arranged between the first end wall 20a and the second end wall 20b. The heating component 30 includes a tube body 31, a heating layer 32 and a protective layer (not shown). The tube body 31 is a hollow structure with both ends through. Specifically, the tube body 31 can be a ceramic tube body and can allow infrared light to pass through. In some other embodiments, the tube body 31 can also be a quartz tube body. The heating layer 32 is arranged on the tube wall of the tube body 31, and is at least partially located between the protective layer (not shown) and the tube body 31, for radiating infrared light waves, which can pass through the tube body 31 to heat the aerosol-generating matrix. The protective layer (not shown) can be arranged on the tube body 31, and its thermal conductivity is lower than the thermal conductivity of the tube body 31, which can enhance the strength of the tube body 31 (especially the strength of the tube body 31 with a smaller thickness), ensure that the tube body 31 has sufficient strength to prevent falling and cracking, and further reduce the heat capacity of the tube body 31, so as to achieve the purpose of rapid heating and improve energy efficiency. Furthermore, providing a protective layer (not shown) allows the tube body to be thinner, thereby increasing the infrared light transmission efficiency of the tube body 31, further improving energy efficiency. This also facilitates controlling the wall temperature of the tube body 31, facilitating control of the temperature within 48 degrees Celsius. This also facilitates the miniaturization of the heating element 30, and consequently, the entire aerosol generating device. In other embodiments, the protective layer (not shown) may be omitted.

[0042] In this embodiment, the tube body 31 is roughly tubular and can be transparent. The tube body 31 is a through-structure at both ends, and its inner side defines a accommodating cavity 310, which can be used to accommodate at least part of the aerosol generating matrix. In some embodiments, the tube body 31 may include a first end face 311, a second end face 312, an outer side face 313, and an inner side face 314. The first end face 311 and the second end face 312 are arranged opposite to each other, and the second end face 312 and the first end face 311 can be arranged opposite to each other along the axial direction of the tube body 31; that is, the first end face 311 is arranged near the plug-in port 11. In some embodiments, the first end face 311 and the second end face 312 can be annular end faces. The outer side face 313 and the inner side face 314 are arranged between the first end face 311 and the second end face 312, and the outer side face 313 and the inner side face 314 are arranged opposite to each other.

[0043] In this embodiment, the heating layer 32 is a membrane structure, which can be coated on the surface of the tube body 31. Specifically, the heating layer 32 may include an infrared film 321 and a heating film 322. The infrared film 321 is arranged on the outer side 313 of the tube body 31. Specifically, the infrared film 321 can be coated, coated or printed on the outer side of the tube body 31. The infrared film 321 evenly covers the entire outer side of the tube body 31. The heating film 322 can be arranged on the infrared film 321 in this embodiment, and can be formed on the infrared film 321 by coating or printing. The heating film 322 can be arranged longitudinally and can extend along the circumference of the tube body 31. In some embodiments, the heating layer 32 also includes a conductive film 323. There can be two conductive films 323. The two conductive films 323 can be arranged on the infrared film 321 at intervals and respectively connected to the two ends of the heating film 322. In some embodiments, the conductive film 323 can be printed and overlaid on the heating film 322, with the overlapped area being 0.5 mm, thereby ensuring reliable electrical contact. In some embodiments, the infrared film 321, the heating film 322, and the conductive film 323 can be formed using existing technologies. In other embodiments, the infrared film 321 is not limited to being disposed on the outer side 313 of the tube body 31; in other embodiments, it can also be disposed on the inner side 314 of the tube body 31.

[0044] In other embodiments, the infrared film 321 and the heating film 322 are not limited to being independent film structures. The heating layer 32 may also be a conventional infrared heating film that actively generates heat and radiates infrared light when powered. The infrared heating film may be provided on the outer side 313 and the inner side 314 of the tube body 31.

[0045] In this embodiment, a protective layer (not shown) may cover the outer side surface 313 and may cover the first end surface 311 and / or the second end surface 312. The protective layer (not shown) may be coated on the outer periphery of the heating layer 32. In some embodiments, the protective layer (not shown) may completely cover the first end surface 311, the second end surface 312 and the entire outer side surface 313. In some other embodiments, the protective layer (not shown) may also be provided only on the first end surface 311 or only on the second end surface 312. In some other embodiments, the protective layer (not shown) may also be provided only on the outer side surface 313. By providing a protective layer (not shown), in addition to enhancing the strength of the tube body 31, the heating layer 32 may be prevented from being corroded, thereby enhancing the corrosion resistance of the heating component 30, and preventing fouling, which is beneficial to the cleaning of the heating component 30. By setting a protective layer (not shown) on the first end face 311 and / or the second end face 312, a heat insulation effect can be achieved, blocking or slowing down the heat conduction and conduction efficiency from the two end faces, thereby reducing heat loss, improving energy efficiency, and simplifying the manufacturing process of the heating component 30, without the need to deliberately add additional heat insulation structure or additional protective layer on the end face.

[0046] In this embodiment, the protective layer (not shown) is smaller than the thickness of the tube body 31, which is conducive to the miniaturization design of the entire heating component 30. In this embodiment, the protective layer (not shown) and the tube wall of the tube body 31 can be an integral structure. Specifically, the material that can be selected for the protective layer (not shown) is glass glaze, which can be formed into an integral structure with the tube body 31 through calcination. It should be noted that glaze is a continuous glassy layer attached to the surface of the ceramic body, or a mixed layer of glass and crystals. It is made by grinding mineral raw materials (quartz) and raw materials in a certain proportion to make glaze slurry, applying it to the surface of the body, and calcining it at a certain temperature. In some other embodiments, the protective layer (not shown) may not be limited to glass glaze.

[0047] In this embodiment, the thermal conductivity of the protective layer (not shown) is much lower than that of the tube body 31, and the infrared transmittance of the protective layer (not shown) is low, thereby reducing the outward transmission of infrared light waves. Specifically, in some embodiments, the infrared emissivity of the protective layer (not shown) for wavelengths of 1-10 μm is less than or equal to 0.5, thereby reducing energy consumption.

[0048] For example Figure 4 and Figure 5 As shown, in this embodiment, the aerosol generating device further includes a first thermal insulation structure 40a, which can be arranged at one end of the heating component 30 facing the plug port 11. Specifically, the first thermal insulation structure 40a can be arranged in the fixed component 20, and can be annular, and can be sleeved on one end of the heating component 30 facing the opening 221. The first thermal insulation structure 40a can be coaxially arranged with the tube body 31 and the opening 221, and be connected with the opening 221 and the tube body 31. By providing the first thermal insulation structure 40a, it not only plays a protective role for the tube body 31, but also plays a heat insulation role. By providing the first thermal insulation structure 40a, the conduction of heat to the fixed component 20 or even the outer shell 10 can be blocked or reduced, thereby reducing heat loss and improving energy efficiency.

[0049] In this embodiment, the first thermal insulation structure 40a may include a sleeve portion 41 and a partition portion 42. The sleeve portion 41 and the partition portion 42 may both be hollow columnar structures, and the cross-section may be roughly circular. The sleeve portion 41 may be sleeved on the heating component 30, and its outer diameter may be larger than the outer diameter of the heating component 30. In some other embodiments, the sleeve portion 41 may also be docked with the heating component 30. The partition portion 42 may be provided on the sleeve portion 41 and extend toward the plug-in port 11 to isolate external debris from the heating component 30 and prevent debris from entering the heating component 30. The external debris may be debris generated by friction during installation of other components in the fixing component 20.

[0050] In this embodiment, the material of the first thermal insulation structure 40a can be zirconia ceramic. Zirconia ceramic is chosen because during rapid preheating, the temperature of the tube body 31 facing the opening 221 may reach a maximum of approximately 400°C, and the temperature of the first end surface 311 may also reach approximately 350°C. While other organic materials (such as PEEK, plastic, and rubber) have relatively poor high-temperature resistance, zirconia ceramic has superior high-temperature resistance and can directly contact the first end surface 311.

[0051] In this embodiment, the aerosol generating device may include a second thermal insulation structure 40b, and the second thermal insulation structure 40b may be arranged at the end of the heating component 30 away from the plug port 11, that is, close to the second end face 312. The second thermal insulation structure 40b may be annular, specifically, it may be circular, which can be accommodated in the fixing seat 21 and coaxially arranged with the tube body 31 to directly contact the end face of the heating component 30. In some embodiments, the high temperature resistance of the second thermal insulation structure 40b may be lower than that of the first thermal insulation structure 40a. In some embodiments, the second thermal insulation structure 40b may be a colloid structure, such as silica gel. Furthermore, the second thermal insulation structure 40b may be selected as a vapor phase glue (silicone made by a vapor phase method), which can withstand a temperature greater than 320°C.

[0052] In this embodiment, the aerosol generating device further includes a third thermal insulation structure 40c, which is disposed around the heating component 30 and is a thermal insulation structure with low high temperature resistance. The third thermal insulation structure 40c can be disposed around the heating component 30. The third thermal insulation structure 40c is disposed between the outer sidewall of the heating component 30 and the inner sidewall of the fixing component 20. Specifically, in this embodiment, the third thermal insulation structure 40c can be a gap. In other embodiments, the third thermal insulation structure 40c is not limited to a gap and can also be an aerogel layer or a vapor-phase glue.

[0053] In this embodiment, the aerosol-generating device further includes a sealing structure 50, which is disposed on the side of the first thermal insulation structure 40a facing the insertion port 11 and is in close contact with the end wall of the fixing sleeve 22. In some embodiments, the sealing structure 50 may be a rubber ring. The sealing structure 50 can be separated from the heating element 30 by the partition portion 42 of the first thermal insulation structure 40a, thereby preventing debris generated by the sealing structure 50 from entering the heating element 30.

[0054] like Figure 7 and Figure 8As shown, in this embodiment, the aerosol generating device also includes a shock-absorbing structure 60. The shock-absorbing structure 60 may be two, namely, a first shock-absorbing structure 60a and a second shock-absorbing structure 60b. One of the shock-absorbing structures 60 is disposed between the first end wall 20a and the tube body 31, specifically, it can be disposed in a fixing groove. The first shock-absorbing structure 60a is disposed between the first end wall 20a and the second thermal insulation structure 40b. The other shock-absorbing structure 60 (i.e., the second shock-absorbing structure 60b) is disposed between the second end wall 20b and the tube body 31. Specifically, it can be sleeved on the outer periphery of the first thermal insulation structure 40a and located between the sleeve portion 41 of the first thermal insulation structure 40a and the second end wall 20b, that is, it is disposed between the tube body 31 and the second end wall 20b. The two shock-absorbing structures 60 can be distributed at both ends of the tube body 31, indirectly contacting the tube body 31, and cooperating with each other to clamp the tube body 31. In other embodiments, the first thermal insulation structure 40a and the second thermal insulation structure 40b may be omitted, and the shock-absorbing structure 60 may be in direct contact with the tube body 31, that is, in direct contact with the first end surface 311 and the second end surface 312. In other embodiments, the number of shock-absorbing structures 60 is not limited to two, and may be one. The shock-absorbing structure 60 may be disposed only between the first end wall 20a and the tube body 31, or only between the second end wall 20b and the tube body 31.

[0055] The provision of the shock-absorbing structure 60 can prolong the impact time when the aerosol generating device is dropped, reduce the impact force on the tube body 31, and reduce the mass of the aerosol generating device, thereby preventing damage to key components during the drop of the aerosol generating device. By reducing the force on the tube body 31 or relieving the stress on the tube body 31, stress concentration can be avoided.

[0056] In this embodiment, the shock-absorbing structure 60 may be annular as a whole, specifically a circular ring, and may be coaxially arranged with the tube body 31. The outer diameter of the shock-absorbing structure 60 may be larger than the outer diameter of the tube body 31. The shock-absorbing structure 60 may include an annular body 61 and an elastic member 62. The annular body 61 may be roughly annular, including an inner ring wall 611 and an outer ring wall 612 arranged on the inner ring wall 611. The elastic member 62 is at least partially arranged on the annular body 61, specifically between the inner ring wall 611 and the outer ring wall 612. In some embodiments, the annular body 61 may be made of an injection moldable material, and the annular body 61 and the elastic member 62 may be formed into an integral structure by in-film injection molding, wherein the elastic member 62 may serve as a skeleton for the molding of the annular body 61. The injection moldable material may be a soft glue, which may be formed by wrapping the outer periphery of the elastic member 62 with the injection moldable material by injection molding and filling the elastic member 62. In some embodiments, the annular body 61 may be silicone. The elastic member 62 may be one, and it may be in the shape of a longitudinal spiral, which may be arranged to extend circumferentially along the annular body 61. In some embodiments, the elastic member 62 may be a spring. Of course, it is understandable that in other embodiments, the elastic member 62 may not be limited to a spring. In this embodiment, the outer diameter of the elastic member 62 may be greater than or equal to the wall thickness of the annular body 61, and the elastic member 62 may partially protrude from the end face of the annular body 61 or be flush with the end face of the annular body 61. Of course, in other embodiments, the elastic member 62 may also be wrapped in the annular body 61. The shock absorbing structure 60 adopts a small damping form to ensure that the tube body 31 has a certain space for adaptive adjustment (elastic deformation space) during the falling process. In some embodiments, the elastic member 62 can be omitted, and the shock absorbing structure 60 as a whole is an elastic structure, such as a silicone ring as a whole. In some embodiments, the sealing structure 50 may also serve as the shock absorbing structure 60.

[0057] In this embodiment, the first shock-absorbing structure 60a and the second shock-absorbing structure 60b can have the same structure. The difference between the two is that the outer diameter of the elastic member 62 in the first shock-absorbing structure 60a can be greater than the wall thickness of the annular body 61, while the outer diameter of the elastic member 62 in the second shock-absorbing structure 60b can be equal to the wall thickness of the annular body 61. In other embodiments, the outer diameters of the elastic members 62 in the first shock-absorbing structure 60a and the second shock-absorbing structure 60b can also be the same. In other embodiments, the first shock-absorbing structure 60a and the second shock-absorbing structure 60b can also have different structures.

[0058] Figure 9 and Figure 10 A second embodiment of the aerosol generating device of the present invention is shown. The difference between the second embodiment and the first embodiment is that the aerosol generating device may include only one shock absorbing structure 60 .

[0059] In this embodiment, there may be multiple elastic members 62, which may be spaced apart along the circumference of the annular body. Specifically, the elastic members 62 may be an even number, such as four, six, eight, or twelve. Providing an even number of elastic members 62 ensures uniform force on the end faces of the tubular body 31. Each elastic member 62 may be in the shape of a spiral column, with its axis parallel to the central axis of the annular body 61. The ends of each elastic member 62 may face the end faces of the annular body 61, protruding from or flush with the end faces.

[0060] Figure 11 The third embodiment of the aerosol generating device of the present invention is shown. It differs from the second embodiment in that the elastic member 62 can be a single piece and is in the shape of a spiral column, the axis of which can coincide with the central axis of the annular body 61. The elastic member 62 can be disposed close to the inner annular wall 611.

[0061] Figure 12 The fourth embodiment of the aerosol-generating device of the present invention is shown. This embodiment differs from the third embodiment in that two elastic members 62 may be provided, namely, the elastic members 62 may include a first elastic member 62a and a second elastic member 62b. The first elastic member 62a is disposed between the inner annular wall 611 and the outer annular wall 612, and is positioned adjacent to the inner annular wall 611. The second elastic member 62b is disposed on the outer periphery of the first elastic member 62a, and is positioned adjacent to the outer annular wall 612.

[0062] Figure 13 The fifth embodiment of the aerosol generating device of the present invention is shown. The difference between the fifth embodiment and the first embodiment is that there can be at least two elastic members 62. Specifically, in this embodiment, there can be two elastic members 62, one of which is sleeved on the outer periphery of the other elastic member 62, and both extend along the circumference of the annular body 61, thereby ensuring that the end face of the tube body 31 is subjected to uniform force.
