On the other hand, the infrared light source and the aerosol generating matrix do not come into contact, and the non-contact heating eliminates the problem of the aerosol generating matrix carbonizing and adhering to the surface of the infrared light source, thereby improving the performance stability of the infrared light source and the electronic atomization device.

Detailed Implementation

[0045] It should be noted that, unless otherwise specified, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific implementation should be understood as explanations of the purpose of this application and should not be regarded as undue limitations on this application.

[0046] In the description of the embodiments of this application, it should be noted that the terms "top," "bottom," "length," "width," etc., indicate the orientation or positional relationship based on the appendix. Figure 4 and attached Figure 5 The orientations or positional relationships shown are provided for the convenience of describing the embodiments of this application and for simplification of description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0047] This application provides an electronic atomizing device; please refer to [link / reference]. Figures 1 to 5 It includes a cartridge shell 10, an atomizer base 20, and an infrared light source 60.

[0048] The electronic atomizing device 100 is used to atomize the aerosol generating matrix 70 to generate an aerosol for inhalation by a user. The aerosol generating matrix 70 includes, but is not limited to, pharmaceuticals, nicotine-containing materials, or nicotine-free materials. The aerosol generating matrix 70 is also not limited to liquid or solid. The following embodiments illustrate a solid aerosol generating matrix 70.

[0049] The infrared light source 60 is used to generate a particle beam to irradiate the aerosol generating matrix 70 contained in the containing device 22. That is, the particle beam generated by the infrared light source 60 irradiates the aerosol generating matrix 70, atomizing the aerosol generating matrix 70 to generate aerosol for the user to inhale.

[0050] It should be noted that the aforementioned particle beam can be infrared light generated by infrared light source 60, or it can be a beam generated by infrared light generated by infrared light source 60 after being shaped by other devices, such as a beam generated by light homogenizer 40 or glass cover plate 626.

[0051] Please see Figures 4 to 7 The cartridge shell 10 has a mist outlet channel 11a. The aerosol generated by the aerosol generating matrix 70 is provided to the user for inhalation through the mist outlet channel 11a. It should be noted that the specific method of using the electronic atomizing device 100 is not limited here. For example, the user can inhale the aerosol through the cartridge shell 10 or inhale the aerosol through an additional mouthpiece in conjunction with the cartridge shell 10.

[0052] Please see Figures 3 to 5 The atomizing base 20 is connected to the cartridge shell 10. The atomizing base 20 includes a receiving device 22 that contains an aerosol generating matrix 70. A particle beam generated by an infrared light source 60 is used to irradiate the aerosol generating matrix 70 contained in the receiving device 22. The aerosol generated by the aerosol generating matrix 70 is inhaled by the user through the mist outlet channel 11a of the cartridge shell 10.

[0053] The blocking part 32 is located on the transmission path of the particle beam and is used to block the particle beam from being transmitted to the fog outlet channel 11a. By setting the blocking part 32 on the transmission path of the particle beam, the particle beam can be prevented from being directly radiated out.

[0054] In related technologies, electronic atomizing devices mainly employ heating wires or heating meshes as heating cores. The heating method of these wires or meshes involves heating the air in the atomization chamber, which then atomizes the aerosol matrix. This is an indirect heating atomization method, requiring a long heating time, resulting in slow mist output and low mist consumption. Furthermore, the heating wires are generally made of metal, such as nickel-chromium alloys, which can release small amounts of heavy metals into the atomized aerosol under high-temperature heating. In addition, electronic atomizing devices using heating wires suffer from uneven temperature distribution and localized excessively high temperatures, potentially leading to the generation of harmful substances.

[0055] The electronic atomizing device provided in this application includes an atomizing base 20 comprising a receiving device 22. An infrared light source 60 is used to generate a particle beam to irradiate the aerosol generating matrix 70 contained in the receiving device 22 within the atomizing base 20. On one hand, the particle beam generated by the infrared light source 60 directly irradiates the aerosol generating matrix 70, directly heating it. This results in shorter heating time, faster mist output, and a higher mist consumption ratio, thereby improving both the heating efficiency and mist consumption ratio of the electronic atomizing device 100. Furthermore, the direct irradiation of the aerosol generating matrix 70 by the infrared light source 60 ensures good temperature uniformity, thus improving the taste. On the other hand, by providing a blocking part 32 along the particle beam's transmission path to prevent the particle beam from reaching the mist output channel 11a, direct radiation of the particle beam can be prevented, thus avoiding safety hazards. While improving the safety and reliability of the electronic atomizing device, the blocking part 32 also reflects a portion of the particle beam back to the aerosol generating matrix 70, further enhancing the heating efficiency of the electronic atomizing device. On the other hand, the infrared light source 60 and the aerosol generating matrix 70 do not come into contact, and the non-contact heating eliminates the problem of the aerosol generating matrix 70 carbonizing and adhering to the surface of the infrared light source 60, thereby improving the performance stability of the infrared light source 60 and the electronic atomization device 100.

[0056] Furthermore, the electronic atomizing device provided in this application embodiment does not generate matrix 70 by heating the aerosol with a heating wire, so no heavy metals will be released into the atomized aerosol.

[0057] In one embodiment, please refer to Figures 3 to 5 , Figure 8 as well as Figure 9 The electronic atomizing device 100 includes a cover plate 30, which includes a body 31. The body 31 and the receiving device 22 define an atomizing chamber 100a. An aerosol generating matrix 70 is disposed in the atomizing chamber 100a. The cover plate 30 forms a smoke channel 30a that connects the atomizing chamber 100a and the mist outlet channel 11a. After the aerosol generating matrix 70 is atomized in the atomizing chamber 100a, it is output to the mist outlet channel 11a through the smoke channel 30a.

[0058] Understandably, the particle beam generated by the infrared light source 60 partially irradiates the aerosol matrix 70 within the atomization chamber 100a, while the rest radiates towards the mist outlet channel 11a. To prevent the particle beam from radiating directly out and causing safety hazards, the cover plate 30 is equipped with a blocking part 32 connected to the main body 31. The blocking part 32 is located on the transmission path of the particle beam and is used to block the particle beam from being transmitted to the mist outlet channel 11a. This prevents the particle beam from radiating directly out through the mist outlet channel 11a, thereby improving the safety and reliability of the electronic atomization device 100.

[0059] It should be noted that the specific arrangement of the body 31 and the blocking part 32 is not limited here. For example, the body 31 and the blocking part 32 can be an integrally formed structure or a separate structure. Furthermore, the specific structure of the body 31 and the blocking part 32 is not limited here. For example, please refer to [link to relevant documentation]. Figure 4 The center of the blocking part 32 nearly coincides with the center of the main body 31. The gap between the main body 31 and the blocking part 32 forms a flue gas channel 30a. This improves the efficiency of mist exiting through the flue gas channel 30a and enhances the effect of the blocking part 32 in blocking particle beam radiation. Additionally, please refer to... Figure 9 The thickness of the blocking part 32 is greater than the thickness of the main body 31, which further improves the effect of the blocking part 32 in blocking particle beam radiation.

[0060] It should be noted that the specific manner in which the flue gas passage 30a is formed is not limited here. For example, in one embodiment, the gap between the body 31 and the blocking part 32 forms the flue gas passage 30a, and the gap between the body 31 and the receiving device 22 forms the atomizing chamber 100a. In other embodiments, the flue gas passage 30a is formed on the body 31.

[0061] In one specific embodiment, the body 31 has a through hole with the same shape as the mist outlet channel 11a. The blocking part 32 is disposed in the through hole, and the two sides of the blocking part 32 along the width direction are connected to the side wall of the through hole. The two sides of the blocking part 32 along the length direction are spaced apart from the side wall of the through hole to form a flue gas channel 30a.

[0062] In one embodiment, please refer to Figure 9The cover plate 30 includes a reflective portion 33 disposed on the side of the blocking portion 32 away from the mist outlet channel 11a. At least part of the particle beam transmitted to the reflective portion 33 can be reflected back to the aerosol generating matrix 70. The reflective portion 33 serves two purposes: firstly, it blocks the particle beam from being transmitted to the mist outlet channel 11a, thereby preventing the particle beam from being directly radiated out through the mist outlet channel 11a, thus improving the safety and reliability of the electronic atomizing device 100; secondly, the reflective portion 33 can further improve the reflection efficiency of the cover plate 30 on the particle beam, reflecting unabsorbed particle beams that have penetrated from the aerosol generating matrix 70 back to the aerosol generating matrix 70, or reflecting particle beams that have bypassed the aerosol generating matrix 70 back to the aerosol generating matrix 70, thereby allowing the particle beam to be absorbed again by the aerosol generating matrix 70, improving the heating efficiency of the infrared light source 60, and increasing the fog consumption ratio. It should be noted that the specific structure of the reflective part 33 is not limited here, as long as it can reflect the unabsorbed particle beam that penetrates the aerosol generating matrix 70 back to the aerosol generating matrix 70, or reflect the particle beam that bypasses the aerosol generating matrix 70 back to the aerosol generating matrix 70. For example, the reflective part 33 can be a reflective film, a reflective coating, or an optical element. For example, the reflective part 33 is a mirror reflective film disposed on the side of the blocking part 32 away from the fog exit channel 11a.

[0063] In some embodiments, the reflective portion 33 includes a substrate and a metal plating layer disposed on the substrate. The substrate includes, but is not limited to, polyester, polyimide (PI), polyester resin (PET), etc.

[0064] In other embodiments, the reflector 33 is an optical element capable of reflecting particle beams, such as a lens, a plane mirror, etc.

[0065] The specific location of the cover plate 30 is not limited here; for example, please refer to [link to relevant documentation]. Figure 4 and Figure 5 The cover plate 30 is located at one end of the mist outlet channel 11a near the atomizing seat 20, so that there is enough space between the body 31 of the cover plate 30 and the receiving device 22 to form the atomizing chamber 100a.

[0066] The specific connection relationship of the cover plate 30 is not limited here. The cover plate 30 can be connected to the atomizer base 20 or to the cartridge shell 10. In addition, the cover plate 30 and the cartridge shell 10 can be a one-piece molded structure or a separate structure.

[0067] For example, please refer to Figure 4 , Figure 5 , Figure 8 as well as Figure 9The main body 31 has a first protrusion 31a on the side away from the atomizing chamber 100a, and the cartridge shell 10 has a groove 10a. The first protrusion 31a is engaged with the groove 10a. During assembly, on the one hand, the cover plate 30 can be positioned by engaging the first protrusion 31a with the groove 10a. On the other hand, the cover plate 30 and the cartridge shell 10 are connected by the first protrusion 31a and the groove 10a. This connection method is simple and improves the connection reliability and assembly efficiency of the cover plate 30 and the cartridge shell 10.

[0068] It should be noted that the specific structure of the first protrusion 31a is not limited here. For example, it can be a first protrusion 31a provided on one side of the body 31, it can be multiple discontinuous first protrusions 31a, or it can be an annular protrusion.

[0069] In other embodiments, the body 31 is provided with a groove 10a or a mounting hole, and the cartridge shell 10 is provided with a first boss 31a that mates with the groove 10a or the mounting hole, and the first boss 31a is engaged in the groove 10a or the mounting hole.

[0070] In one embodiment, please refer to Figure 4 , Figure 5 , Figure 10 as well as Figure 11 The atomizing base 20 includes an atomizing bracket 21 connected to the cartridge shell 10. The atomizing bracket 21 has a first mounting groove 21a. The receiving device 22 is disposed in the first mounting groove 21a to fix the receiving device 22 on the atomizing bracket 21.

[0071] It is understood that the receiving device 22 can be inserted into the first mounting groove 21a by interference fit, or it can be glued to the side wall of the first mounting groove 21a, or it can be limited by setting a buckle 21d to prevent the receiving device 22 from falling out of the first mounting groove 21a.

[0072] Please see Figure 4 , Figure 5 , Figure 10 as well as Figure 11 The atomizing bracket 21 has an incident channel 21b that penetrates the bottom of the first mounting groove 21a. The infrared light source 60 is located on the side of the incident channel 21b away from the receiving device 22. The particle beam generated by the infrared light source 60 is transmitted to the incident channel 21b and then irradiated by the receiving device 22 onto the aerosol generating matrix 70 to atomize the aerosol generating matrix 70.

[0073] In one embodiment, please refer to Figures 4 to 7The cartridge shell 10 includes a mist-emitting column 11 with a mist-emitting channel 11a and an outer shell 12 surrounding the mist-emitting column 11. A groove 10a is formed between the mist-emitting column 11 and the outer shell 12. It should be noted that the connection method between the mist-emitting column 11 and the outer shell 12 is not limited here. For example, the mist-emitting column 11 and the outer shell 12 can be a separate structure or a one-piece structure. In this embodiment, the mist-emitting column 11 and the outer shell 12 are described as a one-piece structure.

[0074] It should be noted that the specific shape of the mist outlet column 11 is not limited here. The shape of the mist outlet column 11 includes, but is not limited to, a hollow cylinder, a hollow elliptical cylinder, a hollow frustum, or a polygon with rounded corners, such as a rounded triangle. For example, in one embodiment, please refer to... Figure 7 The shape of the mist column 11 is a hollow cylinder, and the cross-sectional area of ​​the mist outlet channel 11a is circular, which is conducive to the smooth flow of aerosols in the mist outlet channel 11a.

[0075] It should be noted that the specific shape of the outer shell 12 is not limited here. The shape of the outer shell 12 includes, but is not limited to, a hollow cylinder, a hollow elliptical cylinder, a hollow frustum, or a polygon with rounded corners, such as a rounded triangle. For example, in one embodiment, please refer to... Figure 7 The outer shell 12 is shaped like a hollow frustum. In other words, the outer dimensions of the outer shell 12 gradually increase towards the receiving device 22, while the outer shell 12 gradually shrinks away from the receiving device 22, which improves the aesthetics and compactness of the electronic atomizing device 100.

[0076] A groove 10a is formed between the vapor column 11 and the outer shell 12. A first boss 31a is provided on the side of the main body 31 away from the atomizing chamber 100a, and the first boss 31a is engaged in the groove 10a. During assembly, on the one hand, the cover plate 30 can be positioned by engaging the first boss 31a in the groove 10a between the vapor column 11 and the outer shell 12. On the other hand, the cover plate 30 and the cartridge shell 10 are connected by the first boss 31a and the groove 10a. This connection method is simple and improves the reliability of the connection between the cover plate 30 and the cartridge shell 10 as well as the assembly efficiency.

[0077] Furthermore, by forming a groove 10a between the mist outlet column 11 and the outer shell 12, the main body 31 is inserted into the groove 10a by the first boss 31a, so that the mist outlet column 11, the outer shell 12 and the boss together form an air cavity. The air cavity surrounds the periphery of the mist outlet channel 11a, which can play a heat insulation role. On the one hand, it can reduce the heat transfer to the outer shell 12, thereby improving the problems of the outer shell 12 being too hot to touch and increased energy consumption. On the other hand, it can prevent the aerosol flowing through the mist outlet channel 11a from losing heat and causing the temperature to drop, thus affecting the taste.

[0078] It should be noted that the specific connection structure between the atomizing bracket 21 and the cartridge shell 10 is not limited here. For example, the connection between the atomizing bracket 21 and the cartridge shell 10 can be a snap-fit, plug-in, fastening connection, or adhesive bonding, etc. For an example, please refer to [link to relevant documentation]. Figure 4 , Figure 5 , Figure 10 as well as Figure 11 The end of the atomizing bracket 21 is provided with a second protrusion 21c, the second protrusion 21c is provided with a buckle 21d, and the outer shell 12 is provided with a slot 12a; when the second protrusion 21c extends into the outer shell 12, the buckle 21d engages with the slot 12a to realize the assembly of the atomizing bracket 21 and the cartridge shell 10.

[0079] It should be noted that the specific location of the buckle 21d is not limited. For example, it can be formed on the outer wall of the second boss 21c or at the end of the second boss 21c.

[0080] In order to improve the reliability of the connection structure of the cover plate 30, the end of the second protrusion 21c away from the incident channel 21b abuts against the body 31, which can prevent the first protrusion 31a of the cover plate 30 from coming out of the groove 10a, thereby improving the structural reliability of the electronic atomizing device 100.

[0081] In other embodiments, the end of the atomizing bracket 21 is provided with a second protrusion 21c, the second protrusion 21c is provided with a slot 12a, and the outer shell 12 is provided with a buckle 21d; when the second protrusion 21c extends into the outer shell 12, the buckle 21d engages with the slot 12a to realize the assembly of the atomizing bracket 21 and the cartridge shell 10.

[0082] It should be noted that the specific location of the buckle 21d on the outer casing 12 is not limited. For example, it can be formed on the inner side wall of the outer casing 12 or at the end of the outer casing 12.

[0083] To improve the connection stability of the atomizing bracket 21, the cover plate 30, and the cartridge shell 10, please refer to... Figure 4 , Figure 5 , Figure 10 as well as Figure 11The atomizing bracket 21 has a second protrusion 21c at its end, and a buckle 21d is provided on the second protrusion 21c. The outer shell 12 has a slot 12a. When the second protrusion 21c extends into the outer shell 12, the end of the outer shell 12 abuts against the end of the atomizing bracket 21, and the buckle 21d engages with the slot 12a to assemble the atomizing bracket 21 with the cartridge shell 10. The end of the second protrusion 21c away from the injection channel 21b abuts against the body 31, which can prevent the first protrusion 31a of the cover plate 30 from coming out of the groove 10a. The outer shell 12 has a step facing the second protrusion 21c, and the side of the body 31 away from the atomizing bracket 21 abuts against the end of the vapor column 11 and the step.

[0084] In one embodiment, the containing device 22 can be made of a transparent material, which facilitates the passage of the particle beam through the containing device 22. The containing device 22 is used to contain the aerosol generating matrix 70. The particle beam passes through the containing device 22 and irradiates the aerosol generating matrix 70 contained in the containing device 22 to atomize the aerosol generating matrix 70.

[0085] To facilitate the passage of the particle beam through the containment device 22, the containment device 22 may be made of transparent quartz, transparent ceramic, glass, diamond or diamond-like material, for example, transparent ceramic alumina.

[0086] In one embodiment, please refer to Figure 4 , Figure 5 as well as Figure 14 The containing device 22 is provided with a vent 22a. The atomizing chamber 100a and the incident channel 21b are connected through the vent 22a. On the one hand, by providing the vent 22a on the containing device 22 to connect the atomizing chamber 100a and the incident channel 21b, it is convenient for the user to inhale the aerosol. On the other hand, the vent 22a improves the transmittance of the particle beam through the containing device 22, thereby improving the heating efficiency of the infrared light source 60.

[0087] It should be noted that the specific arrangement of the vent 22a is not limited here. For example, multiple vents 22a are provided, and each vent 22a is spaced apart at the bottom of the receiving device 22. By providing multiple vents 22a and spaced apart at the bottom of the receiving device 22, the air intake efficiency can be improved on the one hand, and on the other hand, it can also prevent that even if some vents 22a are blocked, some vents 22a can still connect to the atomizing chamber 100a and the injection channel 21b.

[0088] Understandably, in order to improve air permeability and prevent the air vent 22a from being blocked, the aperture of the air vent 22a cannot be too small. In order to prevent foreign objects from entering the injection channel 21b from the atomizing chamber 100a through the air vent 22a, the aperture of the air vent 22a cannot be too large. For example, the aperture of the air vent 22a is 0.5mm to 1.5mm.

[0089] The cartridge shell 10, atomizer base 20, and cover plate 30 are connected to form the cartridge part of the electronic atomizing device 100. The electronic atomizing device 100 includes a cigarette rod part, which includes a cigarette rod shell 50 connected to the atomizer base 20. The cartridge part and the cigarette rod part are detachably connected, which facilitates the replacement of the cartridge part.

[0090] In one embodiment, please refer to Figures 3 to 5 The electronic atomizing device 100 includes a light-diffusing element 40. By setting the light-diffusing element 40, on the one hand, the particle beam generated by the infrared light source 60 can be converted into a uniform light spot required by the electronic atomizing device 100. For example, the shape, size and intensity distribution of the light spot can be controlled by the light-diffusing element 40 so that the light spot is uniformly covered on the heated surface of the aerosol generating matrix 70. The temperature uniformity is good, which can avoid the phenomenon of uneven heating temperature distribution and excessively high local heating temperature in the electronic atomizing device 100, which leads to the generation of harmful substances and thus improves the taste. On the other hand, the condensed liquid generated by the user during the inhalation process can flow back to the light-diffusing element 40, thereby preventing the condensed liquid from flowing back to the infrared light source 60 and affecting the performance of the infrared light source 60.

[0091] It should be noted that the specific location of the light-diffusing element 40 is not limited here. For example, along the transmission direction of the particle beam, the light-diffusing element 40 is located upstream of the receiving device 22. That is, the particle beam passes through the light-diffusing element 40 first, and then irradiates the aerosol generating matrix 70 contained in the receiving device 22. For example, the light-diffusing element 40 can be located on the atomizing bracket 21, that is, the light-diffusing element 40 can be located in the cartridge part. In this case, the light-diffusing element 40 can be replaced along with the cartridge part. Alternatively, it can be located in other positions of the electronic atomizing device 100, such as on the cigarette holder 50. In this case, the cost of the cartridge part can be reduced.

[0092] In one embodiment, the light-diffusing element 40 is disposed on the atomizing bracket 21. The specific connection method between the light-diffusing element 40 and the atomizing bracket 21 is not limited here. For example, please refer to [link to relevant documentation]. Figure 4 , Figure 5 , Figure 10 as well as Figure 11A slot 12a is formed on the side wall of the incident channel 21b away from the first mounting groove 21a. The light-diffusing component 40 is embedded in the slot 12a. This assembly method is simple. It is only necessary to embed the light-diffusing component 40 into the slot 12a. It can also prevent the light-diffusing component 40 from being improperly assembled, which would affect the use effect.

[0093] It is understandable that the light-diffusing component 40 can be glued to the slot 12a, and the light-diffusing component 40 can also be limited by the buckle 21d to prevent the light-diffusing component 40 from coming out of the slot 12a.

[0094] In one embodiment, please refer to Figure 4 , Figure 5 , Figure 10 as well as Figure 11 The incident channel 21b has a ventilation groove 21e formed on the side wall of the slot 12a. When the light-diffusing element 40 is embedded in the slot 12a, the incident channel 21b is connected to the outside through the ventilation groove 21e, which makes it convenient for the user to inhale aerosol.

[0095] The specific number of ventilation slots 21e is not limited here. The number of ventilation slots 21e can be one or more. More means two or more. For example, the number of ventilation slots 21e is more than one. By setting multiple ventilation slots 21e, the air intake efficiency can be improved.

[0096] It should be noted that the specific manner in which the particle beam generated by the infrared light source 60 irradiates the aerosol generating matrix 70 contained in the containing device 22 is not limited here. For example, the central axis of the infrared light source 60 may be approximately coincident with the central axis of the incident channel 21b and the fog exit channel 11a. Alternatively, the infrared light source 60 may be located on one side of the incident channel 21b or the fog exit channel 11a, and the particle beam generated by the infrared light source 60 may be transmitted to the incident channel 21b or the fog exit channel 11a through optical elements or the like.

[0097] The specific location of the infrared light source 60 is not limited here. The infrared light source 60 can be set in the cigarette cartridge or in the cigarette rod. For example, the infrared light source 60 is set in the cigarette rod housing 50, which reduces the cost of the cigarette cartridge. In other words, when the cigarette cartridge is replaced, the infrared light source 60 does not need to be replaced along with the cigarette cartridge, thus improving the utilization rate of the infrared light source 60.

[0098] It should be noted that the specific connection method between the e-cigarette housing 50 and the atomizer base 20 is not limited here. For example, please refer to [link to relevant documentation]. Figure 4 , Figure 5 , Figure 12 as well as Figure 13The cigarette holder 50 has a second mounting groove 50a. The end of the atomizing seat 20 away from the mist outlet channel 11a extends into the second mounting groove 50a and is magnetically connected to the cigarette holder 50.

[0099] Specifically, please refer to Figures 3 to 5 The portion of the atomizing base 20 that extends into the second mounting groove 50a is provided with a first magnetic attraction part 23. The bottom of the second mounting groove 50a is provided with a second magnetic attraction part 51 corresponding to the first magnetic attraction part 23. The end of the atomizing base 20 away from the mist outlet channel 11a extends into the second mounting groove 50a. The first magnetic attraction part 23 and the second magnetic attraction part 51 are magnetically connected so that the atomizing base 20 is placed in the second mounting groove 50a of the cigarette holder housing 50.

[0100] The specific arrangement of the first magnetic attraction part 23 and the second magnetic attraction part 51 is not limited here. In one embodiment, the first magnetic attraction part 23 includes a first magnet embedded in the atomizing base 20, and the second magnetic attraction part 51 includes a second magnet embedded in the bottom of the second mounting groove 50a and corresponding to the first magnet.

[0101] The number of first magnets can be multiple, and the number of second magnets corresponds to the number of first magnets.

[0102] In one embodiment, please refer to Figure 4 , Figure 5 , Figure 12 as well as Figure 13 The cigarette holder 50 has an emission channel 50b that extends through the bottom of the second mounting groove 50a. An infrared light source 60 is disposed in the emission channel 50b. The particle beam generated by the infrared light source 60 is transmitted through the emission channel 50b to the incident channel 21b, and then irradiates the aerosol generating matrix 70 through the receiving device 22.

[0103] It should be noted that there is no restriction on the specific type of infrared light source 60. For example, infrared light source 60 can be a thermal radiation infrared light source 61 or a stimulated radiation infrared light source 62.

[0104] The thermal radiation infrared light source 61 heats the radiation unit in the infrared light source 60 to 600~700℃ by electric heating, and uses the molecular thermal motion in the radiation unit to radiate infrared light, with an infrared radiation band of about 3μm.

[0105] Please see Figure 15 The thermal radiation infrared light source 61 includes a focusing structure 614 and an infrared light radiation unit 615 located between the focusing structure 614 and the containing device 22. The infrared light radiation unit 615 can generate infrared light after being powered on. The infrared light is focused by the focusing structure 614 to form a particle beam. The particle beam irradiates the aerosol generating matrix 70 contained in the containing device 22 to heat and atomize the aerosol generating matrix 70.

[0106] The specific structure of the light-concentrating structure 614 is not limited here. For example, it can be a light-concentrating reflective surface, which can be parabolic, ellipsoidal, spherical, hyperboloid, etc. For example, the light-concentrating reflective surface is parabolic.

[0107] Specifically, please refer to Figure 15 The thermal radiation infrared light source 61 includes a first base 611, a first encapsulation housing 612, and a first electrode 613. A focusing reflector is disposed on the first base 611 of the thermal radiation infrared light source 61. An infrared light radiation unit 615 is located between the focusing structure 614 and the housing device 22, and is located at the focal line of the focusing reflector. The infrared light radiation unit 615 is powered through the first electrode 613. After the infrared light radiation unit 615 is powered on, it generates infrared light. After being reflected by the focusing reflector, it forms parallel light that irradiates the aerosol generating matrix 70 contained in the housing device 22, so as to heat and atomize the aerosol generating matrix 70.

[0108] The first base 611 and the first encapsulation shell 612 surround to form a cavity 61a. The inner wall of the cavity 61a is coated with a highly reflective metal film to prevent infrared light from being absorbed by the cavity 61a, thereby improving the radiation efficiency of the infrared light source 60.

[0109] The infrared radiation unit 615 of the thermal radiation infrared light source 61 can be a heating wire, a MEMS (MicroElectro Mechanical Systems) infrared light source 60, etc.

[0110] In one embodiment, please refer to Figure 16 The stimulated emission infrared light source 62 includes a laser diode chip 623, a photodiode 624, a glass cover 626, and a control circuit. The laser diode chip 623 is used to emit laser light, and the photodiode 624 can receive and monitor the laser light. The laser light forms a particle beam after passing through the glass cover 626. The control circuit is signal-connected to both the laser diode chip 623 and the photodiode 624.

[0111] Stimulated emission infrared light source 62, also known as infrared laser diode, is formed by doping a semiconductor to create P-type and N-type regions. The majority carriers in the P-type region are holes, and the majority carriers in the N-type region are electrons. When energized, holes diffuse into the N-type region, and electrons diffuse into the P-type region. Near the PN junction (depletion region), holes and electrons recombine, and excess energy is radiated as photons in the infrared radiation band of 0.8μm-1.5μm.

[0112] Specifically, please refer to Figure 16The stimulated emission infrared light source 62 includes a second base 621, a second encapsulation housing 622, a glass cover 626, a laser diode chip 623, a photodiode 624, and a second electrode 625. Power is supplied to the laser diode chip 623 and the photodiode 624 through the second electrode 625. The laser diode chip 623 emits laser light. The photodiode 624 acts as a laser receiver feedback circuit, receiving and monitoring the laser light emitted by the laser diode chip 623, and outputting a signal to an external control circuit to regulate the required optical power output by the laser diode chip 623.

[0113] The glass cover 626 serves two purposes: dust prevention and beam shaping, adjusting the laser beam to the required spot size.

[0114] The second base 621 can increase the heat dissipation area and promote the transfer of heat generated by the stimulated radiation infrared light source 62 to the surrounding air.
