Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, as one implementation, this application provides an electronic cigarette device, including a cartridge 1, a device body 2, and an end cap 3. The cartridge 1 includes a smoke-generating filling material 101 for generating smoke. The device body 2 is used to accommodate the cartridge 1 and heat the cartridge 1 to generate smoke aerosol. The end cap 3 is used to cover the cartridge 1. The end cap 3 extends the path of the aerosol output from the cartridge 1 to the user's mouth, which helps to reduce the aerosol temperature and improve the safety of using the electronic cigarette device.

[0021] Specifically, the smoke-generating filler 101 is a solid particle, and the smoke-generating filler 101 can generate smoke aerosol under the heating action of the smoking device body 2.

[0022] It should be noted that the smoke-generating filler 101 does not burn during the heating process.

[0023] The main body 2 of the smoking device includes a smoking device shell 201 and a smoke generating component 202. The smoking device shell 201 is used to wrap the smoke generating component 202 to ensure the safety of using the electronic cigarette device. The smoke generating component 202 is used to heat the cigarette cartridge 1 to generate smoke aerosol.

[0024] A smoking cavity 2011 is formed inside the smoking device housing 201. Along the extending direction of the smoking device body 2, the smoking cavity 2011 has a smoking opening 20111, and the smoke generating component 202 is installed in the smoking cavity 2011.

[0025] A generation chamber 2026 is formed inside the smoke generating assembly 202. The generation chamber 2026 is connected to the smoking opening 20111. The tobacco cartridge 1 is installed in the generation chamber 2026 through the smoking opening 20111.

[0026] The cartridge 1 extends at least partially beyond the smoking opening 20111, making it easy for the user to replace the cartridge 1. At the same time, it can shorten the length of the smoke generating component 202 and reduce the production cost of the electronic cigarette device.

[0027] The end cap 3 is installed on the end of the main body 2 of the smoking device that has a smoking opening 20111, so that the end cap 3 covers the end of the cartridge 1 that extends out of the smoking opening 20111. A smoking channel 301 is formed inside the end cap 3, and the user inhales the smoke aerosol generated by the cartridge 1 through the smoking channel 301.

[0028] The smoking device housing 201 also has an opening groove 2012, which is connected to the smoking device cavity 2011. The opening groove 2012 and the smoking opening 20111 are located at the same end of the smoking device housing 201, that is, the opening groove 2012 and the smoking opening 20111 are both located at the end of the smoking device housing 201 facing the end cover 3.

[0029] The opening slot 2012 provides an air inlet for the electronic cigarette device. At the same time, the opening slot 2012 also serves as an anti-interference slot to prevent interference between the end cap 3 and the main body 2 of the device. By setting the opening slot 2012, the air inlet of the electronic cigarette device can be hidden, which improves the overall aesthetics of the electronic cigarette device and prevents the air inlet from becoming blocked. This ensures that external air can enter the electronic cigarette device stably, thereby ensuring the stability of the suction resistance of the electronic cigarette device and improving the vaping experience.

[0030] Specifically, the end cap 3 has a rotational degree of freedom to swing relative to the main body 2 of the smoking device. That is, the end cap 3 can swing relative to the main body 2 of the smoking device. By installing the end cap 3 in a swingable manner on the main body 2 of the smoking device, the connection strength between the end cap 3 and the main body 2 of the smoking device can be effectively improved.

[0031] During the swinging process of end cap 3, end cap 3 has an open state and a closed state.

[0032] When the end cap 3 is in the closed state, the end cap 3 covers the smoking device housing 201, so that the end cap 3 covers the end of the cigarette cartridge 1 that extends out of the smoking opening 20111. At this time, the end cap 3 is separated from the opening groove 2012, and the smoking channel 301 is connected to the generating chamber 2026, so that air flows from the opening groove 2012 through the generating chamber 2026 and the smoking channel 301 in sequence, so that the user can inhale the smoke aerosol generated by the cigarette cartridge 1.

[0033] When the end cap 3 is in the open state, the end cap 3 swings relative to the smoking device housing 201, creating a gap between the end cap 3 and the smoking device housing 201 for the user to replace the tobacco cartridge 1. At this time, the smoking channel 301 separates from the generating chamber 2026, and at least a portion of the end cap 3 extends into the opening groove 2012 to facilitate the user to install or remove the tobacco cartridge 1.

[0034] To more clearly illustrate the technical solution of this application, the following definitions are provided: Figure 1 The directions shown are up, down, left, and right. The extension direction of the main body 2 of the smoking device is... Figure 1 In the vertical direction, the end cap 3 swings within the plane formed by the vertical and horizontal directions.

[0035] As one implementation, the opening groove 2012 is an L-shaped groove, and the opening groove 2012 is a groove-shaped structure extending toward the smoking device cavity 2011. The opening of the opening groove 2012 includes a vertical groove portion 20121 and a horizontal groove portion 20122.

[0036] When the end cap 3 is in the closed state, the end cap 3 is at least partially separated from the transverse groove 20122, so that the smoking channel 301 is connected to the generating chamber 2026, thereby allowing air to flow into the smoking device body 2 from the transverse groove 20122.

[0037] In one implementation, the end cap 3 is installed on the smoking device housing 201 via the rotating shaft 4. The opening groove 2012 is located on the side of the smoking opening 20111 facing the rotating shaft 4. The end cap 3 swings around the axis of the rotating shaft 4. When the end cap 3 is in the open state, the end of the end cap 3 near the rotating shaft 4 swings into the transverse groove 20122 of the opening groove 2012.

[0038] It should be noted that, along Figure 1 As shown in the left-right direction, the smoking opening 20111 includes a left side and a right side, the rotating shaft 4 is located on the right side of the smoking device body 2, and the opening groove 2012 is located on the right side of the smoking opening 20111.

[0039] When the end cap 3 is in the closed state, an air intake gap 5 is formed between the end cap 3 and the smoke appliance housing 201, ensuring that air enters the opening slot 2012 through the air intake gap 5, and is then transported to the smoke generating component 202 by the opening slot 2012.

[0040] It should be noted that the intake gap 5 can be formed by the left and right misalignment of the end cover 3 and the opening groove 2012, or by the vertical misalignment of the end cover 3 and the opening groove 2012, or by the vertical and horizontal misalignment of the end cover 3 and the opening groove 2012.

[0041] Furthermore, in this implementation, along the extension direction of the smoking device body 2, the projection of the end cap 3 is at least partially located inside the projection of the opening groove 2012, thereby causing the end cap 3 and the opening groove 2012 to be misaligned, that is, the end cap 3 and the opening groove 2012 are misaligned to the left and right, thereby forming the air intake gap 5.

[0042] As one implementation, the end cap 3 includes a mounting cover 302 and a sleeve cover 303. The mounting cover 302 is mounted on the smoking device housing 201 via a rotating shaft 4, and the sleeve cover 303 is fitted over the mounting cover 302.

[0043] Furthermore, when the end cap 3 is in the closed state, along the extension direction of the smoking body 2, the projection of the mounting cover 302 is at least partially located within the projection range of the opening groove 2012, thereby causing the mounting cover 302 to be at least partially misaligned with the opening groove 2012, so as to form an air intake gap 5 between the mounting cover 302 and the opening groove 2012.

[0044] Along the extension direction of the smoking device body 2, the projection of the opening groove 2012 is located within the projection of the cover 303, ensuring that the cover 303 can close the smoking device body 2.

[0045] Furthermore, the end face of the mounting cover 302 facing the main body 2 and the end face of the sleeve cover 303 facing the main body 2 are located in the same plane. When the end cover 3 is in the closed state, the end faces of the mounting cover 302 and the sleeve cover 303 facing the main body 2 are basically in contact with the end face of the main body 2 facing the end cover 3, reducing the gap between the end cover 3 and the main body 2, thereby preventing foreign objects from entering the electronic cigarette device. Figure 3-4 As shown, in one implementation, a cover groove 3031 is formed at the end of the cover 303 facing the housing 201 of the e-cigarette. The cover groove 3031 is located on the side of the cover 303 near the rotating shaft 4, that is, the cover groove 3031 is located on the right side of the cover 303. By setting the cover groove 3031, interference between the end cover 3 and the e-cigarette body 2 can be further prevented. At the same time, the cover groove 3031 can further increase the opening of the air intake gap 5, further ensuring that air can stably enter the air intake gap 5, thereby ensuring the suction resistance stability of the e-cigarette and improving the smoking experience of the e-cigarette.

[0046] When the end cap 3 is in the open state, the mounting cover 302 is at least partially located in the opening groove 2012, and at least part of the smoking device housing 201 is located in the cover groove 3031, to prevent interference between the smoking device housing 201 and the cover 303.

[0047] When the end cap 3 is in the closed state, the cover groove 3031 is connected to the air intake gap 5. The opening of the air intake gap 5 is increased by the cover groove 3031, which ensures the stability of the suction resistance of the electronic cigarette and improves the smoking experience of the electronic cigarette.

[0048] It should be noted that when the end cap 3 is in the closed state, there is a certain gap between the groove wall of the cover groove 3031 and the end face of the smoking device body 2 facing the end cap 3, thereby preventing the end cap 3 from closing the air intake gap 5.

[0049] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in one implementation, the smoking device housing 201 includes an outer shell body 2013, a housing cover 2014, and a mounting bracket 2015. Along the extending direction of the smoking device body 2, the outer shell body 2013 has a mounting opening 20131, the housing cover 2014 is installed in the mounting opening 20131, the outer shell body 2013 and the housing cover 2014 are assembled to form a smoking device cavity 2011, the mounting bracket 2015 is fixedly installed in the smoking device cavity 2011, and the mounting bracket 2015 extends to the outside of the smoking device housing 201 through a vertical groove 20121, thereby facilitating the connection between the end cap 3 and the mounting bracket 2015.

[0050] like Figure 6 and Figure 8 As shown, specifically, the housing cover 2014 includes a fastening part 20141, an arched part 20142 and a connecting part 20143, and the arched part 20142 is connected to the fastening part 20141 through the connecting part 20143.

[0051] The fastening part 20141 is snapped into the internal groove 20132 of the outer shell body 2013, and the connecting part 20143 extends toward the end cover 3. When the end cover 3 is in the closed state, the arched part 20142 is located inside the end cover 3.

[0052] The smoking opening 20111 is located in the middle of the arched part 20142, and the opening groove 2012 is located on the side of the connecting part 20143 near the rotating shaft 4, that is, the opening groove 2012 is located on the rightmost side of the connecting part 20143.

[0053] Meanwhile, the opening groove 2012 extends at least partially to the fastening part 20141. On the one hand, it prevents the end cap 3 from interfering with the fastening part 20141 during the swinging process. On the other hand, it can further increase the air intake of the electronic cigarette device, thereby ensuring the suction resistance stability of the electronic cigarette device.

[0054] like Figure 7 As shown, in one implementation, the mounting bracket 2015 includes a mounting part 20151 and a first connecting seat 20152 and a second connecting seat 20153 connected to the mounting part 20151. A through hole 20151a is formed in the mounting part 20151. Along the left-right direction, the first connecting seat 20152 and the second connecting seat 20153 are respectively located on both sides of the through hole 20151a. The through hole 20151a is used to install the flue gas generating assembly 202.

[0055] The mounting part 20151 is fixed inside the outer casing 2013 by screws and other components.

[0056] The first connecting seat 20152 extends at least partially outside the opening slot 2012 via the vertical groove 20121, and the end cover 3 is connected to the first connecting seat 20152 via the rotating shaft 4.

[0057] like Figure 2 As shown, in one implementation, the electronic cigarette device also includes a locking component 7 and an unlocking component 8. The locking component 7 is rotatably mounted on the second connecting seat 20153 via a rotating shaft, and the unlocking component 8 is rotatably mounted in the cigarette device cavity 2011 via a rotating shaft. The unlocking component 8 is at least partially connected to the locking component 7, thereby causing the locking component 7 to swing through the unlocking component 8.

[0058] The locking member 7 includes a locking portion 701 located inside the connecting portion 20143 and extending at least partially outside the connecting portion 20143 to lock the end cap 3.

[0059] It should be noted that the locking member 7 and the second connecting seat 20153 are connected by a torsion spring. The torsion spring applies a force to the locking member 7. Under the action of the torsion spring, the locking part 701 normally extends at least partially beyond the connecting part 20143, thereby locking the end cover 3.

[0060] The unlocking member 8 extends at least partially outside the outer shell body 2013 so that the user can press the unlocking member 8. By pressing the unlocking member 8, the locking member 7 is driven to swing, thereby separating the locking part 701 from the end cover 3 and unlocking the end cover 3.

[0061] like Figure 9As shown, in one implementation, the smoke generating assembly 202 includes a heating housing 2021 and a heating component 2022. The generating chamber 2026 is located inside the heating housing 2021. The heating component 2022 is installed on the side of the generating chamber 2026 away from the end cap 3. The smoke cartridge 1 is detachably installed on the side of the generating chamber 2026 facing the end cap 3.

[0062] Specifically, the heating housing 2021 includes a first sleeve 20211, a second sleeve 20212, a limiting ring 20213, and a base 20214. The generating chamber 2026 is located inside the first sleeve 20211, the second sleeve 20212 is installed inside the first sleeve 20211, and the base 20214 is installed at the end of the first sleeve 20211 away from the end cover 3, thereby limiting the second sleeve 20212 to be located inside the first sleeve 20211.

[0063] The heating component 2022 is installed inside the second sleeve 20212, and a stop portion 20212a is formed at the end of the second sleeve 20212 facing the cartridge 1. The stop portion 20212a confines the heating component 2022 inside the second sleeve 20212. At the same time, the setting of the stop portion 20212a creates a heat transfer gap 2025 between the cartridge 1 and the heating component 2022, preventing the heating component 2022 from directly contacting the cartridge 1, thereby preventing the local temperature of the cartridge 1 from becoming too high and ensuring that the smoke aerosol produced by the cartridge 1 has a good taste.

[0064] like Figure 9 and Figure 10 As shown, in one implementation, the smoke generating component 202 also includes a sleeve 2023. The sleeve 2023 is sleeved outside the heating housing 2021, and an air channel 2024 is formed between the sleeve 2023 and the heating housing 2021. The air flowing into the smoking chamber 2011 from the opening slot 2012 flows through the air channel 2024 to the heating component 2022, and then flows from the heating component 2022 to the smoke cartridge 1, so that the smoke cartridge 1 generates smoke aerosol.

[0065] Specifically, a through hole 20231 is formed at one end of the sleeve 2023 facing the end cap 3, and the air channel 2024 is connected to the opening groove 2012 through the through hole 20231.

[0066] As one implementation method, the bottom of the sleeve 2023 abuts against the base 20214 to ensure a sealed connection between the sleeve 2023 and the base 20214, thereby ensuring the airtightness of the air passage 2024.

[0067] Meanwhile, along the extension direction of the main body 2 of the smoking device, the through hole 20231 is set towards the upper half of the cartridge 1. When air enters the air channel 2024 through the through hole 20231, the air can cool the upper part of the cartridge 1, thereby reducing the temperature of the vapor aerosol produced by the cartridge 1. At the same time, when the heating component 2022 is working, it will transfer heat to the heating shell 2021. After the external air enters the air channel 2024, it contacts the outer wall of the heating shell 2021 and exchanges heat, thereby preheating the air in the air channel 2024. This means that the air flowing to the heating component 2022 has completed the initial heating process. The air temperature after being heated by the heating component 2022 is higher, thereby further improving the taste of the aerosol produced by the cartridge 1.

[0068] Preferably, the through hole 20231 is located above the halfway point of the cartridge 1.

[0069] In one implementation, a wire-passing hole is formed in the base 20214 for threading wires, and the wire harness of the heating component 2022 passes through the wire-passing hole through the base 20214.

[0070] It should be noted that the wiring harness of the heating component 2022 is sealed to the wire hole, ensuring that only the air in the air channel 2024 enters the cartridge 1. At the same time, it can isolate the heated airflow and the smoke generated by the cartridge 1 from the circuit board and other components, preventing the heated airflow and the smoke generated by the cartridge 1 from contaminating the circuit board and other components in the main body 2 of the smoking device through the wire hole.

[0071] As one implementation, the end cover 3 also includes a sealing cover 304, which is located inside the mounting cover 302. When the end cover 3 is in the closed state, a sealing cavity 6 is formed between the sealing cover 304 and the housing cover 2014, and the smoking channel 301 is connected to the generating cavity 2026 through the sealing cavity 6.

[0072] The sealing cover 304 ensures the airtightness of the connection between the smoking channel 301 and the generating chamber 2026, guaranteeing that the smoke aerosol can be stably delivered to the user's mouth.

[0073] As one implementation, the sealing cover 304 includes a U-shaped part 3041 and a cooling part 3042. The U-shaped part 3041 covers the housing cover 2014, thereby forming a sealing cavity 6 between the U-shaped part 3041 and the housing cover 2014.

[0074] By setting the cooling section 3042, the smoke can remain in the sealed cavity 6 for a certain period of time, thereby reducing the temperature of the smoke aerosol output through the smoke extraction channel 301. At the same time, the cooling section 3042 increases the path length of the smoke aerosol output, thereby further reducing the temperature of the smoke aerosol output through the smoke extraction channel 301.

[0075] Furthermore, the cooling section 3042 is located at the top center of the U-shaped section 3041. A through hole is formed in the cooling section 3042. The cooling section 3042 connects the sealing cavity 6 and the smoke channel 301 through the through hole. By setting the through hole, the smoke is further delayed from being transported from the sealing cavity 6 to the smoke channel 301, thereby further reducing the temperature of the smoke aerosol output by the smoke channel 301.

[0076] As one implementation method, along the extension direction of the main body 2 of the smoking device, the cooling part 3042 is connected to the upper end face of the U-shaped part 3041, so that the sealing cavity 6 has a convex structure, thereby further increasing the distance of the smoke from the sealing cavity 6 to the smoking channel 301, and further reducing the temperature of the smoke aerosol output through the smoking channel 301.

[0077] like Figure 11 As shown, in one implementation, the cartridge 1 also includes a cartridge shell 102 and a sealing piece 103, which together form a cartridge cavity for filling the smoke-generating filler 101.

[0078] Specifically, along the extension direction of the cartridge 1, the cartridge shell 102 includes a first opening 1021 and a second opening 1022, and two sealing pieces 103 are respectively installed in the first opening 1021 and the second opening 1022. The sealing pieces 103 and the cartridge shell 102 together form a cartridge cavity, and the smoke-generating filler 101 fills the cartridge cavity.

[0079] The sealing sheet 103 has multiple through holes 1031, which are evenly arranged on the sealing sheet 103. The through holes 1031 ensure that the airflow can flow stably through the cartridge 1, so that the smoke-generating filling material 101 in the cartridge 1 can generate smoke and output the cartridge 1 to the outside.

[0080] The diameter of the through hole 1031 is 0.2 to 0.5 mm, and the ratio of the total area of ​​the multiple through holes 1031 to the total area of ​​the sealing piece 103 is 0.1 to 0.2.

[0081] With the above settings, the draw resistance of this electronic cigarette device can be made close to that of traditional cigarettes, so that the electronic cigarette has a better smoking experience. At the same time, it can also ensure that the smoke-generating filling material 101 can be stably filled in the cartridge 1, preventing the smoke-generating filling material 101 from leaking out of the through hole 1031.

[0082] As one implementation, the sealing sheet 103 has a composite layered structure, comprising an overlapping metal layer and a paper layer. The metal layer is located on the outer side away from the smoke-generating filler 101, and the paper layer is located on the inner side closer to the smoke-generating filler 101. The metal layer material can be one of aluminum foil, tin foil, or gold foil, giving the sealing sheet 103 better strength and preventing damage during e-cigarette use. Simultaneously, the metal layer ensures better waterproof performance, preventing deformation of the sealing sheet 103 due to moisture in the smoke during e-cigarette use, and ensuring that the draw resistance of the cartridge 1 remains essentially unchanged during use. The inner paper layer ensures a more secure bond between the sealing sheet and the cartridge shell 102.

[0083] The sealing sheet 103 is fixed to the first opening 1021 and the second opening 1022 by means of adhesive bonding between the paper surface layer and the cartridge shell 102, thereby closing the first opening 1021 and the second opening 1022.

[0084] It should be noted that the outer diameter of the sealing piece 103 is the same as the outer or inner diameter of the cartridge shell 102, so that the sealing piece 103 covers the end of the cartridge shell 102.

[0085] In one implementation, the cartridge shell 102 includes an outer tube 1023 and an inner tube 1024. The outer tube 1023 is sleeved outside the inner tube 1024, and the smoke-generating filler 101 is filled inside the inner tube 1024.

[0086] As one implementation method, the outer tube 1023 uses cork paper, while the inner tube 1024 uses white paper.

[0087] like Figure 9 and Figure 11 As shown, as one implementation method, the particle size of the smoke-generating filler 101 is 1mm to 1.2mm, so that the draw resistance is similar to that of traditional cigarettes, thereby improving the smoking experience of the electronic cigarette device.

[0088] Preferably, the bulk density of the smoke-generating filler 101 in the smoke cartridge 1 is from 0.00056 g / mm³ to 0.00061 g / mm³.

[0089] Through the above settings, the draw resistance of this electronic cigarette device is further optimized, approaching that of traditional cigarettes, and it has a superior aroma and irritation, resulting in a better smoking experience.

[0090] It should be noted that the smoke-generating filler 101 is a spherical or ellipsoidal solid structure, thereby ensuring that there are certain gaps between the smoke-generating fillers 101. At the same time, the bulk density of the smoke-generating filler 101 is the ratio of the total weight of the smoke-generating filler 101 to the volume of the smoke cartridge cavity.

[0091] Specifically, in this implementation, experiments are conducted on the effect of the particle size of the smoke-generating filler 101 on the draw resistance and the sensory experience of smoking.

[0092] Test Example 1: Absorption Resistance Test.

[0093] First, three types of smoke-generating fillers 101—Particle A, Particle B, and Particle C—with the same flavor but different particle sizes, are filled into different tobacco cartridges 1, forming three different types of tobacco cartridges 1. 100 cartridges of each type are prepared. Specifically, the particle size of Particle A is 0.5mm to 0.9mm; the particle size of Particle B is 1mm to 1.2mm; and the particle size of Particle C is 1.3mm to 1.5mm.

[0094] Three different types of tobacco cartridges were sequentially installed into the same e-cigarette device, and then the device was installed into an electronic cigarette draw resistance tester for draw resistance testing.

[0095] The test results are shown in Table 1: Table 1: Results of the suction resistance test Therefore, it can be seen that the smoke-generating filler 101 with a particle size of 1mm to 1.2mm is closest to the draw resistance of traditional cigarettes, which allows electronic cigarettes to better simulate traditional cigarettes and improve the taste of electronic cigarettes.

[0096] Experimental Example 2: Sensory test of smoking.

[0097] Three types of smoke-generating fillers 101, namely particles A, B, and C, of ​​the same flavor but different particle sizes, are filled into different tobacco cartridges 1 to form three different types of tobacco cartridges 1. The three different types of tobacco cartridges 1 are then installed in the smoking device of this application, and then five professional cigarette evaluation engineers conduct a silent evaluation of the smoking sensory (aroma, smoke volume, irritation intensity, etc.) of the three types of tobacco cartridges from a professional evaluation perspective.

[0098] The evaluation results are shown in Table 2: Table 2: Sensory tests for smoking Therefore, it can be concluded that the smoke-generating filler 101 with a particle size of 1 mm to 1.2 mm has the best evaluation results in terms of smoking sensory properties (aroma, smoke volume, irritation intensity, etc.) and is the optimal particle size.

[0099] Test Example 3: Smoking Accessory Compatibility Test.

[0100] The compatibility of the particle size of the smoke-generating filler 101 with that of the electronic cigarette device was tested.

[0101] Three types of smoke-generating fillers 101, namely particles A, B, and C, with the same flavor but different particle sizes, are filled into different tobacco cartridges 1 to form three different types of tobacco cartridges 1. The three different types of tobacco cartridges 1 are then grouped and installed into three different types of smoking devices. Five professional cigarette evaluation engineers then conduct a comprehensive evaluation based on taste, aroma, and irritation level.

[0102] The evaluation results are shown in Table 3: Table 3: Results of Smoking Accessory Compatibility Test It should be noted that the needle-type smoking device has a heating element inserted into the cartridge, meaning that the needle-type device directly heats the smoke-generating filling 101 inside the cartridge through the heating element, thereby forming smoke. The circumferential type smoking device has a ring-shaped heating element sleeved on the outside of the cartridge, meaning that the circumferential type smoking device heats the outer part of the cartridge through the ring-shaped heating element, transferring heat to the smoke-generating filling 101, thereby forming smoke.

[0103] The test results show that the smoking experience of the smoking device of this application is best when combined with the tobacco cartridge 1 with a particle size of 1mm to 1.2mm for the smoke-generating filling material 101.

Various modifications and variations can be made to this application by those skilled in the art.

[0105] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended claims.
