Description

CROSS-REFERENCE TO PRIOR APPLICATION

Priority is claimed to Chinese Patent Application No. 202310594693.0, filed on May 24, 2023, the entire disclosure of which is hereby incorporated by reference herein.

FIELD

The present invention relates to the field of vaporization technologies, and more specifically, to a vaporization device.

BACKGROUND

An aerosol is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in an air medium. The aerosol can be absorbed by the body through the respiratory system, providing a user with a novel and alternative absorption manner. A vaporization device refers to a device that forms an aerosol through heating or ultrasound by using stored vaporizable media. The vaporizable media include liquid, gel, paste, or a solid aerosol-generating substrate. These media are vaporized, which may deliver an inhalable aerosol to a user, thereby replacing a conventional product form and absorption manner.

Before initial use or after the aerosol-generating substrate is used up, usually the user is required to fill the aerosol-generating substrate. However, this causes a filling amount and quality of the aerosol-generating substrate to be uncontrollable, or other vaporization particles are introduced in a filling process, affecting a user experience.

SUMMARY

In an embodiment, the present invention provides a vaporization device, comprising: a host; a suction nozzle detachably connected to the host; and an aerosol-generating product connected between the host and the suction nozzle, the aerosol-generating product comprising a container, an accommodating cavity being formed in the container, the accommodating cavity being configured to accommodate an aerosol-generating substrate, wherein the host comprises a heating assembly configured to heat the aerosol-generating substrate, and wherein the suction nozzle comprises an air outlet channel through which the accommodating cavity is in communication with an outside.

FIG. 1 to FIG. 4 show a vaporization device 100 in some embodiments of the present invention. The vaporization device 100 is configured to heat an aerosol-generating substrate 33 to generate an aerosol for a user to use. The vaporization device 100 may include a vaporizer 40 and an aerosol-generating product 30 at least partially detachably connected to the vaporizer 40. The aerosol-generating substrate 33 is accommodated in the aerosol-generating product 30. A heating manner of the vaporization device 100 may use one or a combination of heat conduction, electromagnetism, infrared radiation, ultrasound, microwave, plasma, and the like. The aerosol-generating substrate 33 includes, but is not limited to, materials used for objectives such as medical treatment, health-preserving, health, and beauty. The aerosol-generating substrate 33 may include solid, liquid, or gel, or may include any combination of two or more of solid, liquid, or gel.

The aerosol-generating substrate 33 may include one or more of nicotine, nicotine base, nicotine salts, nicotine derivatives, and nicotine analogues. The nicotine salts may be selected from a list including the following items: nicotine citrate, nicotine lactate, nicotine pyruvate, nicotine bitartrate, nicotine pectate, nicotine alginate, and nicotine salicylate.

The aerosol-generating substrate 33 may include an aerosol-forming agent. The term “aerosol-forming agent” is used to describe any proper known compound or mixture of compounds. The aerosol-forming agent helps promote and stabilize formation of an aerosol in use, and is substantially resistant to heat degradation at an operating temperature of the aerosol-generating product 30. The proper aerosol-forming agent includes, but is not limited to: polyols, such as a triethylene glycol, 1,3-butanediol, and glycerin; esters of polyols, such as glycerol monoacetate, glycerol diacetate, or glycerol triacetate; and fatty acid esters of monocarboxylic acid, dicarboxylic acid, or polycarboxylic acid, such as dimethyldodecanedioate and dimethyltetradecanedioate. Preferably, the aerosol-forming agent is a polyol or mixture of the polyol, such as a triethylene glycol, 1,3-butanediol, and glycerol.

The aerosol-generating substrate 33 may further include fragrance. The fragrance may include volatile fragrance components. In some embodiments, the fragrance may include menthol. The term “menthol” is used to indicate any form of the isomer of the compound 2-isopropyl-5-methylcyclohexanol. The fragrance is available in scents selected from menthol, lemon, vanilla, orange, wintergreen, cherry, and cinnamon. The fragrance may include volatile tobacco fragrance compounds that are released from a substrate upon heating.

The aerosol-generating substrate 33 may further include tobacco or a tobacco-containing material. For example, the aerosol-generating substrate 33 may include any one of the following: tobacco leaves, a tobacco vein segment, reconstituted tobacco, homogenized tobacco, extruded tobacco, tobacco slurry, cast leaf tobacco, and expanded tobacco. Optionally, the aerosol-generating substrate 33 may include tobacco powder compressed with, for example, glass or ceramic or another proper inert material. When the aerosol-generating substrate 33 includes liquid or gel, in some embodiments, the aerosol-generating product 30 may include an adsorbent carrier. The aerosol-generating substrate 33 may be coated on the adsorbent carrier or impregnated into the adsorbent carrier. For example, a nicotine compound and the aerosol-forming agent may be combined with water into a liquid formulation. In some embodiments, the liquid formulation may further include the fragrance. The liquid formulation may then be absorbed into the adsorbent carrier or coated on a surface of the adsorbent carrier. The adsorbent carrier may be a sheet or tablet of a cellulose-based material onto which the nicotine compound and the aerosol-forming agent may be coated or absorbed.

When the aerosol-generating substrate 33 includes solid, the aerosol-generation substrate 33 may include one or more forms of solid in the form of pulverized solid, granular solid, powdered solid, granulated solid, strip-shaped solid, or sheet-shaped solid. When the aerosol-generating substrate 33 includes plant-based materials, the aerosol-generating substrate 33 may include one or more of a root, a stem, a leaf, a flower, a bud, a seed, and the like of a plant.

The vaporizer 40 may include a suction nozzle 10 and a host 20 that are connected to each other. The suction nozzle 10 is detachably arranged on an end of the host 20, and an air outlet channel 11 is formed in the suction nozzle 10. The aerosol-generating product 30 is connected between the suction nozzle 10 and the host 20, and is in communication with the air outlet channel 11. The host 20 may generate energy after being powered on to heat the aerosol-generating substrate 33 stored in the aerosol-generating product 30. The aerosol generated after the aerosol-generating substrate 33 is heated may flow out through the air outlet channel 11 for a user to use. The aerosol-generating product 30 is generally designed as a low-volume structure, for example, in some embodiments, a volume of the aerosol-generating product 30 may range from 0.4 mL to 1.6 mL.

In some embodiments, the suction nozzle 10, the host 20, and the aerosol-generating product 30 are detachably assembled together. The aerosol-generating product 30 is preloaded with the aerosol-generating substrate 33. When the aerosol-generating substrate 33 in the aerosol-generating product 30 is used up, the aerosol-generating substrate 33 may be renewed by replacing the aerosol-generating product 30, thereby implementing precise control of the quantity of aerosol-generating substrates 33, ensuring quality of the aerosol-generating substrate 33, and avoiding introduction of other impurities when manually adding the aerosol-generating substrate 33. In addition, because the suction nozzle 10 and the host 20 may be reused, a use cost of the vaporization device 100 is reduced. Certainly, when the aerosol-generating substrate 33 in the aerosol-generating product 30 is used up, the aerosol-generating substrate 33 may also be filled into the aerosol-generating product 30 through a known filling device/method.

In some embodiments, one end of the aerosol-generating product 30 may be plugged into the host 20, and the other end of the aerosol-generating product 30 is connected to the suction nozzle 10. A vaporization cavity 240 configured to accommodate the aerosol-generating product 30 may be formed at an end of the host 20 connected to the suction nozzle 10. The vaporization cavity 240 has an insertion port 244 at an end close to the suction nozzle 10. One end of the aerosol-generating product 30 may be inserted into the vaporization cavity 240 from the insertion port 244, and the other end of the aerosol-generating product 30 may extend out of the vaporization cavity 240 to be connected to the suction nozzle 10. In another embodiment, the other end of the aerosol-generating product 30 may not extend out of the vaporization cavity 240. In other words, the aerosol-generating product 30 may be completely accommodated in the vaporization cavity 240. Certainly, in some other embodiments, the aerosol-generating product 30 may also be inserted into the suction nozzle 10.

The host 20 may be connected to the suction nozzle 10 in a magnetic attraction manner, making it easier to assemble or disassemble the suction nozzle 10 to or from the host 20. Specifically, an end of the host 20 that is connected to the suction nozzle 10 has a support portion 211, and the vaporization cavity 240 may be formed on the support portion 211 in a longitudinal direction and may be coaxially arranged with the support portion 211. The support portion 211 may be made of materials such as plastic, and at least one magnetic attraction member 26 may be embedded in the support portion 211. The at least one magnetic attraction member 26 may be a magnet or a magnetic material that may be attracted by a magnet. The host 20 is magnetically connected to the suction nozzle 10 through the magnetic attraction member 26. Correspondingly, at least one magnetic attraction member 16 may be arranged at an end of the suction nozzle 10 connected to the host 20, and the at least one magnetic attraction member 16 is magnetically engaged with the at least one magnetic attraction member 26.

In this embodiment, there are two magnetic attraction members 26, and the two magnetic attraction members 26 may be respectively located on two sides of the support portion 211 in a horizontal direction. Correspondingly, there are also two magnetic attraction members 16, and the two magnetic attraction members 16 are respectively arranged in one-to-one correspondence with the two magnetic attraction members 26. It may be understood that in other embodiments, the support portion 211 may also be made of a magnetic metal material, and therefore, the magnetic attraction member 26 does not need to be arranged. In some other embodiments, the host 20 and the suction nozzle 10 may also be connected together in other detachable manners such as a threaded connection, a snap connection, and the like.

The host 20 may include a housing 21 and a battery 22, a circuit board 23, and a heating assembly 24 that are arranged in the housing 21. The housing 21 has a columnar structure, and a cross-sectional shape of the housing 21 may be various shapes such as a track shape, an ellipse, a circle, a square, and the like, and is not limited herein. The circuit board 23 is electrically connected to the battery 22 and the heating assembly 24 respectively. A control chip and related control circuits are arranged on the circuit board 23, and are configured to implement calculating and controlling on the device. The battery 22 is configured to supply power to electronic components such as the circuit board 23 and the heating assembly 24. The heating assembly 24 is engaged with the aerosol-generating product 30, and is configured to heat the aerosol-generating substrate 33 in the aerosol-generating product 30 after being powered on.

In this embodiment, the battery 22, the circuit board 23, and the heating assembly 24 are respectively accommodated in a lower portion, a middle portion, and an upper portion of the housing 21. In another embodiment, the battery 22, the circuit board 23, and the heating assembly 24 may also be arranged in the housing 21 in other manners. For example, the battery 22 and the circuit board 23 may also be arranged side by side.

In this embodiment, the host 20 heats the aerosol-generating substrate 33 in an electromagnetic induction manner. The heating assembly 24 includes an inductive heating source 242. The inductive heating source 242 is electrically connected to the battery 22, and may generate a fluctuating electromagnetic field after being powered on, to heat a susceptor located in the fluctuating electromagnetic field.

In this embodiment, the heating assembly 24 is in a shape of a tube, and the vaporization cavity 240 is formed in the heating assembly 24. The inductive heating source 242 may include an induction coil 2421. The induction coil 2421 may be wound outside the vaporization cavity 240. Further, the heating assembly 24 may further include a bracket 241 and a magnetic shield 243 arranged outside the induction coil 2421. The bracket 241 is configured to form the vaporization cavity 240, and may be configured to mount and fix the induction coil 2421. The magnetic shield 243 may reduce electromagnetic radiation radiated by the induction coil 2421 to the outside, and may be further configured to fix the induction coil 2421.

The aerosol-generating product 30 is designed to be joined to the electrically operated host 20 that includes the inductive heating source 242. The aerosol-generating product 30 includes a susceptor. The susceptor may be coupled to the inductive heating source 242 and interact with the inductive heating source 242. The term “susceptor” is used to describe materials that may convert electromagnetic energy into heat. When the susceptor is located in the fluctuating electromagnetic field, the fluctuating electromagnetic field may generate eddy currents in the susceptor. The eddy currents may heat the susceptor through ohmic or resistive heating, thereby heating the aerosol-generating substrate 33. When the susceptor includes a ferromagnetic material (such as iron, nickel, and cobalt), the susceptor may be further heated due to hysteresis losses.

The susceptor may be made of any material that may be heated in an induction manner sufficiently to cause the aerosol-generating substrate 33 to generate an aerosol. Proper susceptor materials may include one or more of graphite, molybdenum, silicon carbide, stainless steel, niobium, aluminum, nickel, nickel-including compounds, titanium, metal material composites, and the like. Preferably, the susceptor includes metal or carbon. Further, the susceptor may include or consist of the ferritic material. The ferritic material may include ferritic iron, ferromagnetic alloys (such as ferromagnetic steel or stainless steel), ferromagnetic particles, or ferrite. In some embodiments, the susceptor may be formed by 400 series stainless steel, such as 410 stainless steel, 420 stainless steel, or 430 stainless steel.

It may be understood that in some other embodiments, other heating manners such as heat conduction, infrared radiation, ultrasound, microwave, plasma, and the like may also be used between the heating assembly 24 and the aerosol-generating product 30.

In some other embodiments, the aerosol-generating product 30 and the suction nozzle 10 may also be an integrated structure. The integrated structure formed by the aerosol-generating product 30 and the suction nozzle 10 may be detachably engaged with the host 20, thereby avoiding a problem of cleaning the suction nozzle 10. Because the host 20 may be reused, and the main electronic components such as the battery 22, the circuit board 23, and the heating assembly 24 are concentrated in the host 20, a replacement cost may also be reduced.

In yet another embodiment, the suction nozzle 10 may also be rotatably or slidably mounted on the host 20, and the aerosol-generating product 30 is detachably connected between the suction nozzle 10 and the host 20. The aerosol-generating product 30 may also be updated by rotating or sliding the suction nozzle 10 to cover or expose the aerosol-generating product 30.

FIG. 5 to FIG. 7 show an aerosol-generating product 30 according to a first embodiment of the present invention. In this embodiment, the aerosol-generating product 30 is in a shape of a cylinder, and may include a container 31, a heating element 32, and an aerosol-generating substrate 33. An accommodating cavity 310 is formed in the container 31, and an end of the container 31 has an opening 311 through which the accommodating cavity 310 is in communication with the outside. The aerosol-generating substrate 33 is arranged in the accommodating cavity 310 and may be in communication with the outside through the opening 311. The outside air may enter the accommodating cavity 310 through the opening 311, and then carry an aerosol generated by vaporization of the aerosol-generating substrate 33 and flow out through the opening 311. The heating element 32 includes a susceptor material or is made of a susceptor material, and may be arranged inside or outside the container 31. During use, the aerosol-generating product 30 is joined to the host 20, so that the heating element 32 is located in a fluctuating electromagnetic field generated by an inductive heating source 242. It may be understood that in other embodiments, the heating element 32 may not be arranged in the aerosol-generating product 30, but the aerosol-generating substrate 33 may be heated in other manners such as heat conduction, infrared radiation, ultrasound, microwaves, and plasma. In addition, the aerosol-generating product 30 is also not limited to a shape of a cylinder, and may also be in other shapes such as a shape of a square cylinder, a shape of an elliptical cylinder, or the like.

The container 31 may include a container side wall 312 in a shape of a circular tube and a container bottom wall 313 arranged at an end of the container side wall 312. The container side wall 312 and the container bottom wall 313 define an accommodating cavity 310, and the other end of the container side wall 312 is open to form an opening 311. The heating element 32 and the aerosol-generating substrate 33 may be filled into the accommodating cavity 310 from the opening 311, and the container bottom wall 313 may be configured to support the heating element 32 and the aerosol-generating substrate 33.

The container 31 may be made of high temperature resistant materials such as glass, ceramics, metal, plastic, aluminum foil, and the like. Further, the container 31 may be at least partially made of a transparent material. The term “transparent” is used to describe a material that allows at least a significant proportion of incident light to pass through the material, so that it is possible to see through the material. In the present invention, the substantially transparent material may allow sufficient light to pass through the material, so that the aerosol-generating substrate 33 in the accommodating cavity 310 is visible before vaporization. When the aerosol-generating substrate 33 in the accommodating cavity 310 may also be transparent, the substantially transparent material may further allow smoke or one or more other aerosols generated by the aerosol-generating substrate 33 to be visible during inhaling of the aerosol-generating product 30.

The container 31 may be completely transparent. Alternatively, the container 31 may also have a lower level of transparency, and still transmit sufficient light, so that the aerosol-generating substrate 33 in the accommodating cavity 310 is visible before vaporization, or causing the smoke generated by the aerosol-generating substrate 33 or one or more other aerosols to be visible.

Further, the container 31 may include one or more regions made of a transparent material, so that a part of the aerosol-generating substrate 33 is visible via the one or more regions. In addition, the regions made of the transparent material may be colored, tinted, or colorless.

The heating element 32 may include or be made of a ferromagnetic metal material. The heating element 32 may be arranged in the container 31. On one hand, the heating element 32 may be in direct contact with the aerosol-generating substrate 33, and the heat generated by the heating element 32 may be directly transferred to the aerosol-generating substrate 33, thereby improving heat transfer efficiency. On the other hand, the container 31 may play a heat insulation role, and reduce the heat transferred outward by the heating element 32.

In some embodiments, a heating cavity 320 is formed in the heating element 32, and the aerosol-generating substrate 33 is accommodated in the heating cavity 320. Specifically, in this embodiment, the heating element 32 is a metal tube in a shape of a cylinder, which may include a heating side wall 321 in a shape of a circular tube and a heating bottom wall 322 arranged at an end of the heating side wall 321. The heating side wall 321 and the heating bottom wall 322 jointly define the heating cavity 320. The heating bottom wall 322 may be supported on a container bottom wall 313. An opening 323 is formed at an end of the heating element 32 opposite to the heating bottom wall 322. The aerosol-generating substrate 33 may be filled into the heating element 32 through the opening 323 and supported on the heating bottom wall 322. During assembly, the aerosol-generating substrate 33 may be first filled into the heating element 32, and then put together into the container 31; or the heating element 32 may also be first placed into the container 31, and then the aerosol-generating substrate 33 is filled into the heating element 32.

An outer diameter of the heating side wall 321 is less than an inner diameter of the container side wall 312. On one hand, the heating element 32 may be more easily assembled into the container 31. On the other hand, a gap 3210 may be formed between an outer surface of the heating side wall 321 and an inner surface of the container side wall 312, which is beneficial to heat insulation, and reduces the heat transferred from the heating side wall 321 to the container side wall 312.

In some embodiments, the gap 3210 may be an annular gap with a capillary force, so that after the aerosol-generating substrate 33 is liquefied in a heating process, the liquid aerosol-generating substrate 33 may enter the gap 3210 through a through hole 3220 provided on the heating element 32, to avoid defects that affect a vaporization effect such as generation of odor due to an excessive temperature between the heating side wall 321 of the heating element 32 and the container 31. It may be understood that in other embodiments, the gap 3210 may also have a non-capillary structure, or some regions may have a non-capillary structure and some regions may have a capillary structure.

There may be one or more through holes 3220, and the one or more through holes 3220 may be provided on the heating side wall 321 and/or the heating bottom wall 322 of the heating element 32. In some embodiments, a pore size of the through hole 3220 may range from 0.5 mm to 1.5 mm. In the range, the-aerosol-generating substrate 33 in the form of a paste may be prevented from flowing out of the through hole 3220, and the liquefied aerosol-generating substrate 33 may flow out of the through hole 3220. Certainly, in another embodiment, the through hole 3220 may not be provided on the heating element 32.

In another embodiment, an outer wall surface of the heating side wall 321 and an inner wall surface of the container side wall 312 may also use fitting manners such as transition fit, interference fit, partial gap fit, or partial interference fit.

It may be understood that in other embodiments, the heating element 32 is not limited to the foregoing structural shape. For example, the heating side wall 321 may also be in a shape of a tapered tube or a stepped tube. For another example, the heating element 32 may also be in a shape of a circular tube without the heating bottom wall 322, or may be in other shapes such as a shape of a U-shaped sheet. In addition, in some other embodiments, the heating element 32 may also be arranged on an outer side of the container 31.

In some embodiments, an isolation layer may be further arranged on an inner surface of the heating element 32, and the isolation layer may include a ceramic glaze layer or a glass glaze layer. By isolating the heating element 32 from the aerosol-generating substrate 33 through the isolation layer, odor that may be generated in the heating process may be further avoided. The through hole 3220 provided on the heating element 32 may further make it easier for the inner surface of the heating element 32 to be coated with glaze in a glaze plating process, thereby ensuring that the heating element 32 is evenly coated with glaze.

Further, in some embodiments, the aerosol-generating product 30 further includes a scaling component 35. The sealing component 35 is arranged at the opening 311 of the container 31, and is configured to seal the opening 311, to prevent the aerosol-generating substrate 33 in the container 31 from flowing out, and prevent external impurities from entering the container 31, thereby ensuring cleanliness inside the container 31. In this embodiment, the sealing component 35 includes a sealing film 351. The sealing film 351 is removably attached to a periphery of the opening 311 to seal the opening 311. During use, the sealing film 351 may be first torn off, to expose the opening 311. In some embodiments, the sealing film 351 may include a body portion 3511 covering the container 31 and a protruding portion 3512 extending outward from an edge of the body portion 3511. The protruding portion 3512 extends outside the container 31, to facilitate a user to tear off the sealing film 351 by pinching the protruding portion 3512. Certainly, in another embodiment, the opening 311 may also be exposed by puncturing the sealing film 351.

In another embodiment, the sealing component 35 may also include other sealing structures. For example, the sealing component 35 may include a thin-walled structure that may be punctured, or may include a sealing plug plugged into the opening 311, or may include a scaling member covering the opening 311.

In some embodiments, the aerosol-generating product 30 may further include a limiting member 34 arranged in the container 31. The limiting member 34 is arranged between the scaling component 35 and the aerosol-generating substrate 33, to prevent the aerosol-generating substrate 33 from flowing onto the sealing component 35 and causing waste. The limiting member 34 may be made of high temperature resistant materials such as metal or non-metal. Further, the limiting member 34 may be made of a material that cannot induce a magnetic field and generate heat, which may prevent the limiting member 34 from dry-burning because the aerosol-generating substrate 33 is fewer in the heating process and is not in contact with the limiting member 34. In another embodiment, the limiting member 34 may also be made of a metal material that may induce a magnetic field and generate heat.

The limiting member 34 may be arranged on an outer side of the heating element 32 or may be arranged in the heating element 32, and/or the limiting member 34 and the heating element 32 may be integrally arranged or separately arranged. In this embodiment, the limiting member 34 includes a mesh sheet 341. The mesh sheet 341 may be a metal mesh sheet. The metal mesh sheet has advantages of high temperature resistance, no pollution, no odor, and a low cost. A plurality of mesh holes 3410 are formed on the mesh sheet 341. Pore sizes of the mesh holes 3410 are in a proper range, which may allow airflow to pass through, and prevent the aerosol-generating substrate 33 from flowing out of the mesh holes 3410. In addition, when the aerosol-generating substrate 33 is heated, the mesh sheet 341 may further prevent the aerosol-generating substrate 33 from sputtering outward. In another embodiment, the limiting member 34 may also include a hot-melt film. The hot-melt film may automatically rupture or burn after being heated, and is non-toxic, odorless, and pollution-free.

In this embodiment, the mesh sheet 341 is arranged on an outer side of the heating element 32 and abuts against an upper end surface of the heating element 32. At least a part of the outer wall surface of the mesh sheet 341 is in contact with an inner wall surface of the container 31, to implement fixation of the mesh sheet 341 in the container 31. Further, at least a part of an outer wall surface of the mesh sheet 341 is in interference fit with the inner wall surface of the container 31, and the mesh sheet 341 is fixed in the container 31 through the interference fit. The fixing manner has a simple structure, is easy to implement, and has high reliability.

In some embodiments, the mesh sheet 341 may include a sheet-shaped body 3411 and a plurality of limiting flanges 3412 extending outward from an outer edge of the sheet-shaped body 3411. The plurality of mesh holes 3410 may be distributed in an even array on the sheet-shaped body 3411, to allow air flow to evenly pass through. The plurality of limiting flanges 3412 may be evenly spaced in a circumferential direction of the sheet-shaped body 3411, so that the mesh sheet 341 is evenly stressed. An outer diameter of the sheet-shaped body 3411 is less than an inner diameter of the container side wall 312, and the mesh sheet 341 is in interference fit with the container side wall 312 through the plurality of limiting flanges 3412, to facilitate the mesh sheet 341 to be mounted into the container 31. It may be understood that in other embodiments, the limiting flanges 3412 may not be arranged on the mesh sheet 341, but may be directly in interference fit with the container side wall 312 through the sheet-shaped body 3411.

As shown in FIG. 3 and FIG. 4, an air outlet channel 11 and an air inlet channel 12 are formed in a suction nozzle 10. The outside air may enter the accommodating cavity 310 through the air inlet channel 12, and then carry the aerosol generated by vaporization of the aerosol-generating substrate 33 and flow out through the air outlet channel 11. It may be understood that in other embodiments, the air inlet channel 12 may also be formed in the host 20, or may be partially formed in the suction nozzle 10 and partially formed in the host 20, or at least a part of the air inlet channel 12 may also be formed between the suction nozzle 10 and the host 20.

In some embodiments, the suction nozzle 10 may include an air guide tube 13, and the air guide tube 13 may be made of high temperature resistant materials such as metal, high temperature resistant plastic (such as polyetheretherketone), and the like. An inner wall surface of the air guide tube 13 defines an air guide channel 130, and the air guide channel 130 may be used for air inlet or air outlet.

In this embodiment, the air guide tube 13 is made of a non-ferromagnetic material. The air guide tube 13 may extend in a longitudinal direction and be coaxially arranged with the opening 311 and the accommodating cavity 310. A lower end of the air guide tube 13 may extend into the opening 311, and may further pass through the opening 311 and extend into the accommodating cavity 310. An end of the air guide tube 13 extending into the accommodating cavity 310 is spaced apart from the mesh sheet 341 and/or the aerosol-generating substrate 33. An outer diameter of the air guide tube 13 is less than an inner diameter of the opening 311, so that an annular vent gap 3111 is formed between an outer wall surface of the air guide tube 13 and an inner wall surface of the opening 311, and the vent gap 3111 may be used for air flow to pass through. One of the vent gap 3111 and the air guide channel 130 is used for air inlet, and the other of the vent gap 3111 and the air guide channel 130 is used for air outlet. It may be understood that in other embodiments, the air guide tube 13 and the opening 311 may also be arranged asynchronously.

In some embodiments, the air inlet channel 12 may include at least one side air inlet passage 121 in communication with the outside and at least one inner air inlet passage 122 communicating the at least one side air inlet passage 121 with the accommodating cavity 310. Specifically, in this embodiment, there are two side air inlet passages 121, to ensure sufficient air inlet. The two side air inlet passages 121 may be symmetrically provided on two opposite sides of the suction nozzle 10, and each side air inlet passage 121 extends inward in a horizontal direction from the outer side surface of the suction nozzle 10. There is one inner air inlet passage 122, and the inner air inlet passage 122 extends in a longitudinal direction and may be coaxially arranged with the accommodating cavity 310. Two ends in a longitudinal direction of the inner air inlet passage 122 are in communication with the side air inlet passage 121 and the accommodating cavity 310 respectively. Specifically, in this embodiment, the inner air inlet passage 122 is formed by the air guide channel 130.

the air outlet channel 11 may include an exhaust channel 112 in communication with the outside and a communication channel 111 connecting the accommodating cavity 310 with the exhaust channel 112. The exhaust channel 112 may be formed by a top surface of the suction nozzle 10 extending downward in a longitudinal direction, and the communication channel 111 is provided on an outer side of the air guide tube 13. The aerosol generated by vaporization of the aerosol-generating substrate 33 may flow out through the vent gap 3111, the communication channel 111, and the exhaust channel 112 from bottom to top.

A specific structure of the communication channel 111 may be flexibly designed as required. For example, the communication channel 111 may include an annular airflow channel surrounding the air guide tube 13. For another example, the communication channel 111 may also include a plurality of edge airflow channels spaced apart in a circumferential direction of the air guide tube 13.

In some embodiments, a flow blocking structure may be further arranged in the air outlet channel 11. The flow blocking structure is used to block a part of the air outlet channel 11, to prevent the aerosol-generating substrate 33 from splashing out of the suction nozzle 10 upon being heated. Certainly, the mesh sheet 341 arranged in the accommodating cavity 310 may also prevent the aerosol-generating substrate 33 from splashing out of the suction nozzle 10 upon being heated. Further, in some embodiments, an auxiliary airflow hole may be further provided on a side wall of the suction nozzle 10, and the auxiliary airflow hole is in communication with the communication channel 111. In the vaporization process, the air in the external environment may further flow into the communication channel 111 from the auxiliary airflow hole, and then mix with the aerosol in the communication channel 111 to reduce concentration of the aerosol, causing the aerosol-generating substrate 33 to be vaporized with low oxygen, and adjusting a temperature of the airflow flowing out of the suction nozzle 10.

In some embodiments, the vaporization device 100 may further include a temperature sensor 14 electrically connected to a circuit board 23. The temperature sensor 14 is at least partially arranged in the air outlet channel 11, and is configured to detect a temperature of the air flow in the air outlet channel 11, and transmit the temperature data to the circuit board 23. A related control circuit is arranged on the circuit board 23, which may control a heating power of the heating assembly 24 according to the temperature data, and may determine whether dry burning is occurring according to the temperature data. In this embodiment, the temperature sensor 14 is a thermocouple, which may be arranged at an end of the exhaust channel 112 close to the communication channel 111. In another embodiment, the temperature sensor 14 may also use other sensor structures such as a thermistor, and/or the temperature sensor 14 may also be arranged at other locations in the air outlet channel 11.

Further, the suction nozzle 10 further includes two first electrodes 15 that are electrically connected to the temperature sensor 14. The host 20 further includes two second electrodes 25 that are electrically connected to the circuit board 23. The two first electrodes 15 and the two second electrodes 25 are in communication with each other through contact conduction. When the suction nozzle 10 is separated from the host 20, the first electrode 15 is separated from the second electrode 25; and when the suction nozzle 10 is connected to the host 20, the first electrode 15 and the second electrode 25 are conducted upon abutting against each other, so that the temperature sensor 14 electrically connected to the circuit board 23. In this embodiment, both the first electrode 15 and the second electrode 25 are electrode posts, and the first electrode 15 and/or the second electrode 25 are elastic, to improve reliability of electrical connection. In another embodiment, the first electrode 15 and/or the second electrode 25 may also include other conductive connection structures such as a conductive elastic piece. In addition, a quantity of first electrodes 15 and second electrodes 25 is not limited to two.

FIG. 8 shows an aerosol-generating product 30 according to a second embodiment of the present invention. Similar to the first embodiment, the aerosol-generating product 30 in this embodiment is also in a shape of a cylinder and includes a container 31, a heating element 32, an aerosol-generating substrate 33, a mesh sheet 341, and a scaling film 351.

Different from the aerosol-generating product 30 in the first embodiment, the container 31 in this embodiment is an aluminum foil paper tube with two ends open. Because the container 31 in this embodiment does not have a container bottom wall 313 that may play a role of supporting, at least a part of the outer wall surface of the heating element 32 may be in interference fit with the inner wall surface of the container 31. The heating element 32 is fixed in the container 31 through interference fit. Further, to reduce heat transferred from the heating element 32 to the container 31 and avoid burning the paper tube, a manner of interference fit between a part of the outer wall surface of the heating element 32 and the inner wall surface of the container 31, and gap fit between a part of the outer wall surface and the inner wall surface of the container 31 may be used. A bottom end of the heating element 32 away from the mesh sheet 341 may extend out of the container 31, or may not extend out of the container 31.

The heating element 32 is a metal tube, and includes a heating side wall 321 in a shape of a circular tube and a heating bottom wall 322 arranged at an end of the heating side wall 321. In some embodiments, the heating side wall 321 may include a first side wall 3211 at an end close to the heating bottom wall 322 and a second side wall 3212 at an end away from the heating bottom wall 322. An outer diameter of the second side wall 3212 may be greater than an outer diameter of the first side wall 3211. According to a first aspect, an outer peripheral surface of the second side wall 3212 is interference fit with an inner peripheral surface of the container 31, to implement fixation of the heating element 32 in the container 31. According to a second aspect, an outer peripheral surface of the first side wall 3211 is in gap fit with an inner peripheral surface of the container 31, which may reduce the heat transferred from the heating element 32 to the container 31 and avoid burning the paper tube. According to a third aspect, the aerosol-generating substrate 33 is mainly arranged in the first side wall 3211 close to the heating bottom wall 322. The first side wall 3211 is a main heating region. The first side wall 3211 is arranged in gap fit with the container 31, and the second side wall 3212 is arranged in interference fit with the container 31, which is more conducive to reducing the heat transferred from the heating element 32 to the container 31.

The mesh sheet 341 may be supported on an upper end surface of the heating element 32, and an outer peripheral surface of the mesh sheet 341 is in interference with an inner peripheral surface of the container 31, thereby implementing fixation of the mesh sheet 341 in the container 31.

A structure of the sealing film 351 is similar to the structure in the first embodiment. This is not repeated herein again.

FIG. 9 shows an aerosol-generating product 30 according to a third embodiment of the present invention. Similar to the first embodiment, the aerosol-generating product 30 in this embodiment is also in a shape of a cylinder and includes a container 31, a heating element 32, an aerosol-generating substrate 33, a mesh sheet 341, and a sealing component 35. A structure of the container 31 and a structure of the mesh sheet 341 are similar to structures in the first embodiment. This is not repeated herein again.

Similar to the first embodiment, the heating element 32 in this embodiment is also a metal tube, and includes a heating side wall 321 in a shape of a circular tube and a heating bottom wall 322 arranged at an end of the heating side wall 321. Different from the first embodiment, in this embodiment, at least one protrusion 324 is formed on the heating bottom wall 322. The heating bottom wall 322 abuts against the container bottom wall 313 of the container 31 through the at least one protrusion 324, which may reduce a direct contact area between the heating bottom wall 322 and the container bottom wall 313, and reduce the heat transferred from the heating element 32 to the container 31.

In addition, different from the first embodiment, the sealing component 35 in this embodiment includes a sealing plug 352. The sealing plug 352 is detachably plugged into the container 31, to seal or open the opening 311.

In some embodiments, the sealing plug 352 may be made of a soft material such as silicone, and may include a sealing portion 3522 sealingly arranged in the opening 311. The sealing plug 352 may further include an exposed portion 3521 and an extending portion 3523 that are respectively arranged at two ends of the sealing portion 3522. The exposed portion 3521 extends outward from an end of the sealing portion 3522 facing away from the accommodating cavity 310. The exposed portion 3521 is at least partially exposed outside the opening 311, to facilitate a user to pull out the sealing plug 352. The extending portion 3523 extends inward from an end of the sealing portion 3522 toward the accommodating cavity 310. An end of the extending portion 3523 away from the sealing portion 3522 may press against the mesh sheet 341, thereby pressing the mesh sheet 341 and the heating element 32 against the container bottom wall 313. In another embodiment, an end of the extending portion 3523 away from the sealing portion 3522 may also be spaced apart from the mesh sheet 341. An outer diameter of the extending portion 3523 may be less than an inner diameter of the container 31, which may reduce a force required for the sealing plug 352 to be assembled into the container 31.

It may be understood that in other embodiments, the sealing plug 352 may also be connected to the container 31 in a non-detachable manner. In this case, a vent hole for air flow may be provided on the sealing plug 352.

FIG. 10 to FIG. 11 show an aerosol-generating product 30 according to a fourth embodiment of the present invention. A difference between the fourth embodiment and the third embodiment is that the mesh sheet 341 in this embodiment is arranged in the heating element 32.

the mesh sheet 341 may include a sheet-shaped body 3411 and a plurality of limiting flanges 3412 extending outward from an outer edge of the sheet-shaped body 3411. A plurality of mesh holes 3410 are provided on the sheet-shaped body 3411. The plurality of limiting flanges 3412 may be evenly spaced in a circumferential direction of the sheet-shaped body 3411.

The heating element 32 is a metal tube, and includes a heating side wall 321 in a shape of a circular tube and a heating bottom wall 322 arranged at an end of the heating side wall 321. at least one protrusion 324 is formed on an outer surface of the heating bottom wall 322. The heating bottom wall 322 abuts against the container bottom wall 313 of the container 31 through the at least one protrusion 324, which may reduce a direct contact area between the heating bottom wall 322 and the container bottom wall 313, and reduce the heat transferred from the heating element 32 to the container 31.

In some embodiments, the heating side wall 321 may include a first side wall 3211 at an end close to the heating bottom wall 322 and a second side wall 3212 at an end away from the heating bottom wall 322. An outer diameter of the second side wall 3212 is greater than an outer diameter of the first side wall 3211. An outer peripheral surface of the first side wall 3211 is in gap fit with an inner peripheral surface of the container 31, which may reduce the heat transferred from the heating element 32 to the container 31.

An inner diameter of the second side wall 3212 is greater than an inner diameter of the first side wall 3211, so that a step surface 3213 is formed at a joint on an inner side between the second side wall 3212 and the first side wall 3211, and the mesh sheet 341 may be arranged in the second side wall 3212 and abut against the step surface 3213. Further, in some embodiments, a plurality of slots 3214 respectively corresponding to a plurality of limiting flanges 3412 may be further formed on the second side wall 3212. The plurality of limiting flanges 3412 may be respectively engaged in the plurality of slots 3214, to implement fixation of the mesh sheet 341 in the second side wall 3212.

Circumferential fixation of the heating element 32 in the container 31 may be implemented through interference fit between the limiting flange 3412 and the container side wall 312, and may also be implemented through interference fit between the second side wall 3212 and the container side wall 312.

FIG. 12 and FIG. 13 show an aerosol-generating product 30 according to a fifth embodiment of the present invention. The aerosol-generating product 30 in this embodiment is in a shape of a cylinder and includes a container 31, a heating element 32, an aerosol-generating substrate 33, and a scaling plug 352. A structure of the container 31 and a structure of the sealing plug 352 are similar to structures in the third embodiment. This is not repeated herein again.

In this embodiment, the heating element 32 is a metal cylinder and is mounted in the container 31 in an upside down manner. Specifically, the heating element 32 includes a heating side wall 321 in a shape of a circular tube and a heating bottom wall 322 arranged at an end of the heating side wall 321. The heating bottom wall 322 is located at an end of the heating side wall 321 away from a container bottom wall 313. At least one vent hole 3221 for air flow is further provided on the heating bottom wall 322, so that the external air may enter the heating element 32, and then carry the aerosol generated by vaporization of the aerosol-generating substrate 33 in the heating element 32 to flow out. Further, to ensure even air flow, a plurality of vent holes 3221 provided in an even array may be provided on the heating bottom wall 322. A pore size of each vent hole 3221 is in a proper range, which may prevent the aerosol-generating substrate 33 from flowing out of the vent hole 3221.

An opening 323 is formed at an end of the heating side wall 321 opposite to the heating bottom wall 322. When assembling the aerosol-generating product 30, the heating bottom wall 322 of the heating element 32 may be first placed downward, so that the opening 323 faces upward, and then the aerosol-generating substrate 33 is injected into the heating element 32 via the opening 323 through an injection device. Because the pore size of the vent hole 3221 is small and the aerosol-generating substrate 33 has a specific viscosity when the aerosol-generating substrate 33 is in the form of a paste, the aerosol-generating substrate 33 does not easily flow out of the vent hole 3221. After the aerosol-generating substrate 33 is injected into the heating element 32, the heating element 32 is mounted upside down into the container 31, so that the opening 323 of the heating element 32 faces the container bottom wall 313, and the heating bottom wall 322 is away from the container bottom wall 313.

It may be understood that in this embodiment, the heating bottom wall 322 may function as the mesh sheet 341 in the foregoing embodiment, so that an additional mesh sheet 341 does not need to be arranged in the aerosol-generating product 30 in this embodiment, which reduces a cost.

FIG. 14 and FIG. 15 show an aerosol-generating product 30 according to a sixth embodiment of the present invention. The aerosol-generating product 30 in this embodiment includes a container 31, a heating element 32, an aerosol-generating substrate 33, a sealing film 351, a sealing plug 352, and a fixed member 36.

The container 31 is a glass tube in a shape of a cylinder, and may include a container side wall 312 in a shape of a tube and a container bottom wall 313 arranged at an end of the container side wall 312. The container side wall 312 and the container bottom wall 313 jointly define an accommodating cavity 310 with an opening 311 at an end. The aerosol-generating substrate 33 is arranged in the accommodating cavity 310, and a form of the aerosol-generating substrate 33 may include gel, paste or, solid.

The heating element 32 is arranged in the accommodating cavity 310 and is at least partially in contact with the aerosol-generating substrate 33. The heating element 32 may induce a magnetic field in an electromagnetic environment and generate heat, thereby heating the aerosol-generating substrate 33. In this embodiment, the heating element 32 is generally in a shape of a U-shaped sheet, and may include the heating bottom wall 322 and two heating side walls 321 separately extending upward from two ends of the heating bottom wall 322 in a horizontal direction. The heating bottom wall 322 is in a shape of a sheet and may be supported on the container bottom wall 313. The two heating side walls 321 are separately located at two edges on two sides of a length of the heating bottom wall 322 and may be perpendicular to the heating bottom wall 322. A length of the heating bottom wall 322 is less than an inner diameter of the container side wall 312. On one hand, the heating element 32 may be more easily assembled into the container 31. On the other hand, a gap may be formed between an outer surface of the heating side wall 321 and an inner surface of the container side wall 312, which is beneficial to heat insulation, and reduces the heat transferred from the heating side wall 321 to the container side wall 312.

The aerosol-generating substrate 33 is at least partially arranged between the two heating side walls 321. In this embodiment, the aerosol-generating substrate 33 is in contact with the inner wall surface and the outer wall surface of the two heating side walls 321 and the heating bottom wall 322, so that a contact area between the aerosol-generating substrate 33 and the heating element 32 is greater, which facilitates heat transfer from the heating element 32 to the aerosol-generating substrate 33.

It may be understood that in other embodiments, the heating element 32 is not limited to the foregoing structural shape. For example, the heating side wall 321 may not be perpendicular to the heating bottom wall 322, and/or a quantity of heating side walls 321 may also be three or more. Certainly, there may be only one heating side wall 321, for example, the heating element 32 has an inverted T-shaped and sheet-shaped structure.

In some embodiments, an isolation layer may be further arranged on an inner surface and/or an outer surface of the heating element 32, and the isolation layer may include a ceramic glaze layer or a glass glaze layer. The isolation layer may isolate the heating element 32 from the aerosol-generating substrate 33, so that odor that may be generated in the heating process may be further avoided. A through hole 3220 may also be provided on the heating side wall 321 and/or the heating bottom wall 322. By providing the through hole 3220, a surface of the heating side wall 321 and/or the heating bottom wall 322 may be more easily coated with glaze in a glaze plating process, thereby ensuring that the heating element 32 is evenly coated with glaze. It may be understood that in other embodiments, the through hole 3220 may also not be provided on the heating element 32.

The fixed member 36 is arranged in the container 31, and is configured to implement circumferential fixation of the heating element 32 in the container 31. The fixed member 36 may be made of a high temperature resistant material such as metal or non-metal. Further, the fixed member 36 may be arranged between the sealing plug 352 and the aerosol-generating substrate 33, and the fixed member 36 may further reduce waste caused by the aerosol-generating substrate 33 flowing onto the sealing plug 352. In some embodiments, the fixed member 36 may be made of a material that cannot induce a magnetic field and generate heat, which may prevent the fixed member 36 from dry-burning because the aerosol-generating substrate 33 is fewer in the heating process and is not in contact with the fixed member 36. In another embodiment, the fixed member 36 may also be made of a metal material that may induce a magnetic field and generate heat.

In this embodiment, the fixed member 36 is in a shape of a sheet and is made of a metal material. The metal material has advantages of high temperature resistance, no pollution, no odor, and a low cost. At least a part of the outer wall surface of the fixed member 36 is in interference fit with the inner wall surface of the container 31, and the fixed member 36 is fixed in the container 31 through interference fit.

A circulation hole 360 is provided on the fixed member 36 for air flow to pass through and a through hole 361 is provided on the fixed member 36 for the heating side wall 321 to pass through. In this embodiment, the circulation hole 360 is located in a middle portion of the fixed member 36. There are two through holes 361 and the two through holes 361 are separately located on two opposite sides of the through hole 361. The heating side wall 321 may include a first side wall 3211 extending upward from the heating bottom wall 322 and a second side wall 3212 extending upward from the first side wall 3211. The width of the first side wall 3211 may be equal to the width of the heating bottom wall 322, and may be greater than the width of the second side wall 3212. The first side wall 3211 has the greater width, to increase a heating area. The second side wall 3212 passes through the through hole 361, and a lower end surface of the fixed member 36 may abut against an upper end surface of the first side wall 3211.

It may be understood that in other embodiments, the fixed member 36 may also not be arranged in the aerosol-generating product 30, and fixation of the heating element 32 in the container 31 may be implemented through other structures. For example, an angle between the heating side wall 321 and the heating bottom wall 322 may be set to an obtuse angle, so that an upper end of the heating side wall 321 expands outward and abuts against an inner wall surface of the container 31.

The sealing plug 352 is at least partially sealingly arranged in the opening 311 to seal the opening 311. Generally, at least a part of an outer wall surface of the sealing plug 352 and an inner wall surface of the opening 311 may be sealingly engaged in manners such as interference fit. The sealing plug 352 may be made of a soft material such as silicone, to improve scaling performance of the sealing plug 352, and make it easier to assemble the sealing plug 352 into the container 31. In another embodiment, the sealing plug 352 may also be made of materials with a specific hardness such as plastic. Further, the sealing plug 352 may be at least partially made of a transparent material.

At least one air inlet passage 3525 and at least one air outlet passage 3526 are further formed in the sealing plug 352 and/or between the outer wall surface of the sealing plug 352 and the inner wall surface of the container 31 that allow the accommodating cavity 310 to be in communication with the external air. After the suction nozzle 10, the host 20, and the aerosol-generating product 30 are assembled, the at least one air inlet passage 3525 allows the accommodating cavity 310 to be in communication with the air inlet channel 12. The at least one air outlet passage 3526 allows the accommodating cavity 310 to be in communication with the air outlet channel 11.

A cross-sectional area of the at least one air inlet passage 3525 is not less than a cross-sectional area of the at least one air outlet passage 3526, thereby ensuring sufficient air inlet, and ensuring that the aerosol generated by vaporization of the aerosol-generating substrate 33 may be fully carried out by the air flow. A cross-sectional area of a single air inlet passage 3525 or air outlet passage 3526 is small, so that the aerosol-generating substrate 33 with a specific viscosity is not easily leaked from the air inlet passage 3525 or the air outlet passage 3526.

In this embodiment, both the at least one air inlet passage 3525 and the at least one air outlet passage 3526 are formed in the sealing plug 352. Specifically, one air inlet passage 3525 and a plurality of air outlet passages 3526 are formed in the sealing plug 352. The air inlet passage 3525 is located in a middle portion of the sealing plug 352, and the plurality of air outlet passages 3526 are distributed around a periphery of the air inlet passage 3525. A cross-sectional area of the air inlet passage 3525 is not less than a total cross-sectional area of the plurality of air outlet passages 3526, thereby ensuring sufficient air inlet, and ensuring that the aerosol generated by vaporization of the aerosol-generating substrate 33 may be fully carried out.

Further, in this embodiment, the air inlet passage 3525 is in a shape of a circular hole, and a pore size of the air inlet passage 3525 may range from 2.5 mm to 3.5 mm; or a cross-sectional area of the air inlet passage 3525 may range from 4.5 mm² to 10 mm². In this range, sufficient air inlet may be ensured, and the aerosol-generating substrate 33 may be effectively prevented from leaking from the air inlet passage 3525. The air outlet passage 3526 is in a shape of a waist-shaped hole, and the plurality of air outlet passages 3526 are evenly spaced around a periphery of the air inlet passage 3525. A total cross-sectional area of the plurality of air outlet passages 3526 may range from 2 mm² to 9 mm², to ensure smooth air flow.

It may be understood that in other embodiments, the air inlet passage 3525 and the air outlet passage 3526 are not limited to the foregoing shapes. In addition, a quantity and arrangement of air inlet channel passages 3525 and air outlet passages 3526 are not limited. For example, there is one air outlet passage 3526, and there are a plurality of air inlet passages 3525, and the plurality of air inlet passages 3525 are distributed around a periphery of the air outlet passage 3526. For another example, there are a plurality of air outlet passages 3526 and a plurality of air inlet passages 3525, and the plurality of air outlet passages 3526 may be distributed around a periphery or an internal periphery of the plurality of air inlet passages 3525.

The sealing plug 352 may include a sealing portion 3522 and an extending portion 3523 extending downward from the sealing portion 3522. There is a gap between a lower end surface of the extending portion 3523 and the aerosol-generating substrate 33. An outer wall surface of the sealing portion 3522 is sealingly engaged with an inner wall surface of the container side wall 312. The container side wall 312 may further shrink inward to form a shrinking structure 3121. An inner diameter of the shrinking structure 3121 is less than an outer diameter of the sealing portion 3522, so that a lower end surface of the sealing portion 3522 may abut against the shrinking structure 3121. The shrinking structure 3121 may define an axial position of the sealing portion 3522, and prevent the sealing portion 3522 from moving downward. An upper end inner wall surface of the container side wall 312 may extend inward to form an inner flange 3122, and the inner flange 3122 may prevent the sealing portion 3522 from moving upward. The inner flange 3122 engages with the shrinking structure 3121, to clamp and fix the sealing portion 3522.

An outer diameter of the extending portion 3523 is less than an inner diameter of the container 31, so that an annular airflow channel 3520 is formed between the outer wall surface of the extending portion 3523 and the inner wall surface of the container 31. The air inlet passage 3525 may extend downward in a longitudinal direction from an upper end surface of the scaling portion 3522 to a lower end surface of the extending portion 3523. The air outlet passage 3526 may extend downward in a longitudinal direction from the upper end surface of the sealing portion 3522 to the lower end surface of the sealing portion 3522 and be in communication with the airflow channel 3520. The structure makes a lower end air outlet of the air inlet passage 3525 closer to the aerosol-generating substrate 33 than a lower end air inlet of the air outlet passage 3526. The extending portion 3523 may guide the external air to the aerosol-generating substrate 33 and mix the external air with the aerosol generated after vaporization of the aerosol-generating substrate 33. The mixed gas is distributed in the airflow channel 3520 and then evenly flows into each air outlet passage 3526. It may be understood that in other embodiments, the air inlet passage 3525 may also be in communication with the airflow channel 3520. In other words, the lower end air inlet of the air outlet passage 3526 is closer to the aerosol-generating substrate 33 than the lower end air outlet of the air inlet passage 3525. In other embodiments, the lower end air inlet of the air outlet passage 3526 and the lower end air outlet of the air inlet passage 3525 may also be on a same horizontal plane.

There is a gap between the lower end surface of the extending portion 3523 and the upper end surface of the heating element 32, which is beneficial to heat insulation. In another embodiment, the lower end surface of the extending portion 3523 may also abut against the upper end surface of the heating element 32 or the fixed member 36, to abut against and fix the heating element 32 and the fixed member 36.

A sealing film 351 may be attached to an upper side of the sealing plug 352, and cover at least the air inlet passage 3525 and the air outlet passage 3526. During use, the sealing film 351 may be first torn off, to expose the air inlet passage 3525 and the air outlet passage 3526. In another embodiment, the air inlet passage 3525 and the air outlet passage 3526 may also be exposed by piercing the scaling film 351.

When assembling the aerosol-generating product 30, the heating element 32 may be first mounted into the container 31, then the aerosol-generating substrate 33 is filled into the container 31, then the sealing plug 352 is mounted, and finally the sealing film 351 is attached.

FIG. 16 and FIG. 17 show an aerosol-generating product 30 according to a seventh embodiment of the present invention. Similar to the sixth embodiment, the aerosol-generating product 30 in this embodiment also includes a container 31, a heating element 32, an aerosol-generating substrate 33, a sealing film 351, and a scaling plug 352. A structure of the container 31, a structure of the sealing film 351, and a structure of the sealing plug 352 are similar to structures in the sixth embodiment. This is not repeated herein again.

Similar to the sixth embodiment, the heating element 32 in this embodiment also includes a heating bottom wall 322 and two heating side walls 321 respectively extending upward from two ends of the heating bottom wall 322. Different from the sixth embodiment, in this embodiment, each heating side wall 321 has at least one wing portion 325 extending toward a direction of the inner wall surface of the container 31. In this embodiment, there are a plurality of wing portions 325. The plurality of wing portions 325 separately extend from two edges on two sides in a horizontal direction of the heating side wall 321 toward a direction away from the heating bottom wall 322, and may be perpendicular to the heating side wall 321. Certainly, in another embodiment, the wing portion 325 and the heating side wall 321 may also be arranged at an acute angle or an obtuse angle. The heating element 32 may abut against the inner wall surface of the container 31 through the wing portion 325, so that the heating element 32 may be fixed in the container 31, and the fixed member 36 does not need to be arranged in the container 31.

It may be understood that in other embodiments, the fixed member 36 or a limiting member 34 may also be arranged in the container 31, to prevent the aerosol-generating substrate 33 from flowing to the sealing plug 352.

FIG. 18 shows an aerosol-generating product 30 according to an eighth embodiment of the present invention. Similar to the sixth embodiment, the aerosol-generating product 30 in this embodiment includes a container 31, a heating element 32, an aerosol-generating substrate 33, a scaling film 351, and a sealing plug 352.

Different from the sixth embodiment, the heating element 32 in this embodiment is in a shape of a cylinder, and may include a heating side wall 321 in a shape of a circular tube and a heating bottom wall 322 arranged at an end of the heating side wall 321. The heating element 32 in this embodiment may be used as a container, to accommodate the aerosol-generating substrate 33. A through hole 3220 may be further provided on the heating side wall 321 and/or the heating bottom wall 322, to ensure that the heating element 32 is evenly glazed. In some embodiments, a pore size of the through hole 3220 may range from 0.5 mm to 1.5 mm. In the range, the aerosol-generating substrate 33 in the form of a paste may be prevented from flowing out of the through hole 3220.

An outer diameter of the heating side wall 321 may be less than or equal to an inner diameter of the container 31. When the outer diameter of the heating side wall 321 is equal to the inner diameter of the container 31, the outer wall surface of the heating side wall 321 is in contact with the inner wall surface of the container 31, thereby directly limiting the heating element 32. When the outer diameter of the heating side wall 321 is less than the inner diameter of the container 31, the outer wall surface of the heating side wall 321 is not in contact with the inner wall surface of the container 31, which is beneficial to heat insulation and assembly. In this case, other limiting structures may be set to limit the heating element 32.

In addition, a difference between this embodiment and the sixth embodiment is that a plurality of air inlet passages 3525 and at least one air outlet passage 3526 are formed in the sealing plug 352 in this embodiment. The plurality of air inlet passages 3525 are distributed around a periphery of the at least one air outlet passage 3526, and a total cross-sectional area of the plurality of air inlet passages 3525 is not less than a cross-sectional area of the at least one air outlet passage 3526.

When assembling the aerosol-generating product 30, the aerosol-generating substrate 33 may be first filled into the heating element 32, and then put together into the container 31, then the sealing plug 352 is mounted, and finally the sealing film 351 is attached. Alternatively, the heating element 32 may also be first placed into the container 31, then the aerosol-generating substrate 33 is filled into the heating element 32, then the sealing plug 352 is mounted, and finally the sealing film 351 is attached.

FIG. 19 shows an aerosol-generating product 30 according to a ninth embodiment of the present invention. A difference between this embodiment and the sixth embodiment is that an air outlet passage 3526 in this embodiment is formed between an outer wall surface of a sealing plug 352 and an inner wall surface of a container 31, and a side air outlet passage 3525 is formed in the sealing plug 352.

Specifically, there may be a plurality of air outlet passages 3526, and the plurality of air passages 3526 may be formed by recesses on an outer wall surface of the sealing portion 3522 and may be evenly spaced in a circumferential direction of the sealing portion 3522.

It may be understood that in other embodiments, alternatively, the air inlet passage 3525 may be formed between the outer wall surface of the sealing plug 352 and the inner wall surface of the container 31, and the air outlet passage 3526 is formed in the sealing plug 352. Alternatively, both the air inlet passage 3525 and the air outlet passage 3526 may be formed between the outer wall surface of the sealing plug 352 and the inner wall surface of the container 31.

FIG. 20 and FIG. 21 show an aerosol-generating product 30 according to a tenth embodiment of the present invention. The aerosol-generating product 30 in this embodiment includes a container 31, an aerosol-generating substrate 33, a sealing member 38, and a sealing film 351. An accommodating cavity 310 with an opening 311 at an end is formed in the container 31, and the aerosol-generating substrate 33 is arranged in the accommodating cavity 310. The sealing member 38 is arranged at the opening 311, and has a first state for sealing the opening 311 and a second state for opening the opening 311.

Specifically, in this embodiment, the container 31 includes a container body 316 and a container cover 317 arranged at an end of the container body 316. The opening 311 is formed on the container cover 317. The container body 316 is in a shape of a cylinder, and may include a container side wall 312 in a shape of a tube and a container bottom wall 313 arranged at an end of the container side wall 312. The container side wall 312 and the container bottom wall 313 jointly define an accommodating cavity 310 configured to accommodate the aerosol-generating substrate 33. An other end of the container side wall 312 is open to form an opening 318, and the container cover 317 is arranged at the opening 318 to cover the opening 318.

The container body 316 may be made of high temperature resistant materials such as glass, ceramics, metal, plastic, and the like. In this embodiment, the container body 316 is made of a ferromagnetic metal material, and may induce a magnetic field in an electromagnetic environment and generate heat, thereby heating the aerosol-generating substrate 33.

The container cover 317 may be made of high temperature resistant materials such as glass, ceramics, metal, plastic, and the like. The container cover 317 may be embedded in the opening 318. In some embodiments, the container cover 317 may be in interference fit in the opening 318 by riveting. Because the container cover 317 is usually not in contact with the aerosol-generating substrate 33, to avoid dry burning, the container cover 317 may be made of a material that does not generate heat or generates less heat in a magnetic field. In this embodiment, the container cover 317 is made of a non-ferromagnetic metal material.

It may be understood that in other embodiments, when the container body 316 and the container cover 317 are made of the same material, for example, when the container body 316 and the container cover 317 are made of a non-ferromagnetic material or a ferromagnetic metal material, the container body 316 and the container cover 317 may also be integrally formed.

The container cover 317 may include an annular sheet-shaped end cover 3171, an inner side wall 3172 extending downward from an inner edge of the end cover 3171, and an outer side wall 3173 extending downward from an outer edge of the end cover 3171. The outer side wall 3173 is sealingly engaged with an inner wall surface of the container side wall 312, and an inner wall surface of the inner side wall 3172 defines the opening 311. An outer diameter of the inner side wall 3172 is less than an inner diameter of the outer side wall 3173, so that an annular space 3174 is formed between an outer wall surface of the inner side wall 3172 and an inner wall surface of the outer side wall 3173. The structure is beneficial to reducing materials and costs, and reducing the weight of the aerosol-generating product 30.

The sealing member 38 is at least partially detachably arranged at the opening 311. In a first state, the sealing member 38 may seal the opening 311, so that the aerosol-generating substrate 33 in the container 31 cannot flow out of the opening 311, to ensure that the aerosol-generating substrate 33 in the container 31 does not leak when the aerosol-generating product 30 is placed upright, upside down, or tilted. In a second state, the sealing member 38 may open the opening 311, so that the accommodating cavity 310 may be in communication with the outside through the opening 311, to implement air inlet and air outlet of the aerosol-generating product 30. In the second state, the sealing member 38 may be completely separated from the opening 311, or may be partially separated from the opening 311 while the other part remains connected to the opening 311.

Further, in the second state, the sealing member 38 is at least partially located in the accommodating cavity 310. In this way, when the aerosol-generating product 30 is placed upside down or tilted, causing the aerosol-generating substrate 33 to remain on the sealing member 38, the aerosol-generating substrate 33 remaining on the sealing member 38 may be heated in the accommodating cavity 310 for further use, thereby reducing or avoiding waste of the aerosol-generating substrate 33.

In this embodiment, the sealing member 38 is completely detachably arranged at the opening 311, and is configured to be pressed and fall into the accommodating cavity 310 in the first state. In this way, when heating is required for use, the sealing member 38 may be pushed into the accommodating cavity 310 by pressing. In addition, the aerosol-generating substrate 33 remaining on the sealing member 38 falls into the accommodating cavity 310 along with the sealing member 38, thereby preventing the aerosol-generating substrate 33 from being wasted.

In addition, when the opening 311 is in an open state, because the inner side wall 3172 of the container cover 317 extends into the accommodating cavity 310 and surrounds the outside of the opening 311, the inner side wall 3172 of the container cover 317 may also block the aerosol-generating substrate 33 from flowing out of the opening 311. Preferably, a bottom surface of the inner side wall 3172 is spaced apart from a top surface of the aerosol-generating substrate 33. In addition, when the aerosol-generating substrate 33 is in the form of a paste, a liquid level when the aerosol-generating substrate 33 is heated and liquefied is lower than the bottom surface of the inner side wall 3172.

Specifically, the sealing member 38 may include a sealing side wall 381 in a shape of a tube and a sealing bottom wall 382 arranged at an end of the sealing side wall 381. The sealing side wall 381 is in a shape of a hollow tube, which is beneficial to reducing materials and costs, and reducing the weight of the aerosol-generating product 30. The sealing side wall 381 is configured to be sealingly engaged with an inner wall surface of the opening 311 in the first state, and the sealing bottom wall 382 may cover the opening 311 and receive pressure from an external force. There is a specific bonding strength between the outer wall surface of the sealing side wall 381 and the inner wall surface of the opening 311. When the pressing force on the sealing bottom wall 382 is greater than the binding force, the sealing member 38 may be away from the opening 311 and fall into the accommodating cavity 310, thereby opening the opening 311.

Further, the sealing side wall 381 may be in a shape of a tapered tube. Specifically, the scaling side wall 381 has an inner end (or lower end) facing into the accommodating cavity 310 and an outer end (or upper end) away from the accommodating cavity 310. A cross-sectional area of the scaling side wall 381 gradually decreases from the inner end to the outer end. Correspondingly, a cross-sectional area of the opening 311 also gradually decreases in a direction from the inner end to the outer end. On one hand, the tapered design may prevent the scaling member 38 from protruding upward, and on the other hand, the tapered design may facilitate the scaling member 38 to disengage downward from the opening 311 when pressed.

The sealing side wall 381 may be in interference fit with the inner wall surface of the opening 311 in manners such as clamping, to ensure that the sealing member 38 does not fall off easily. In some embodiments, the sealing side wall 381 may include a plurality of clamping arms 3811 spaced apart in a circumferential direction. The sealing member 38 is in interference fit with the inner wall surface of the opening 311 through the plurality of clamping arms 3811. In this embodiment, there are three clamping arms 3811 and the three clamping arms 3811 are evenly spaced in a circumferential direction of the sealing side wall 381, which is beneficial to even force receiving. In another embodiment, a quantity of clamping arms 3811 may also be two or more.

In this embodiment, the scaling bottom wall 382 is arranged at a lower end of the sealing side wall 381, an upper end of the sealing side wall 381 is open. A plurality of grooves 3810 spaced apart in a circumferential direction may be formed on the upper end of the sealing side wall 381. Each groove 3810 may extend downward from the upper end surface of the sealing side wall 381 but does not penetrate the lower end surface of the sealing side wall 381. The plurality of grooves 3810 divide an upper half of the sealing side wall 381 into clamping arms 3811 and body portions 3812 that are alternately distributed in a circumferential direction. The length of the clamping arm 3811 in the circumferential direction may be less than the length of the body portion 3812 in the circumferential direction. The groove 3810 is provided so that the clamping arm 3811 may expand outward to be in interference fit with the inner wall surface of the opening 311. A lower half of the sealing side wall 381 is closed in the circumferential direction, and a groove structure is not formed on the lower half of the sealing side wall 381, which may prevent the aerosol-generating substrate 33 from leaking to the outside through the groove 3810.

It may be understood that in other embodiments, the sealing member 38 is not limited to the foregoing structural form. For example, the sealing bottom wall 382 may also be arranged on the upper end of the sealing side wall 381. For another example, the sealing member 38 may also be of a solid structure. For another example, the sealing side wall 381 may also protrude outward to form a convex structure, and is in interference with the inner wall surface of the opening 311 through the convex structure.

The sealing member 38 may be made of high temperature resistant materials such as metal, plastic, and the like. In this embodiment, the sealing member 38 is made of a non-ferromagnetic metal material. It may be understood that because the sealing member 38 may be in contact with the aerosol-generating substrate 33 after falling into the accommodating cavity 310. In other embodiments, the sealing member 38 may also be made of a ferromagnetic metal material. In this case, the container body 316 may be made of a ferromagnetic material or a non-ferromagnetic material. In some other embodiments, both the sealing member 38 and the container body 316 may be made of non-ferromagnetic materials, and electromagnetic induction heating may be performed by arranging an additional heating element outside or inside the container body 316.

The sealing film 351 at least covers the sealing member 38, to ensure cleanliness of the sealing member 38, and further prevent the sealing member 38 from being mistakenly pressed into the container 31 before use. The sealing film 351 may be a tearable sealing film and is attached to the upper end surface of the container 31. During use, the sealing film 351 may be first torn off, to expose the sealing member 38. In another embodiment, the sealing member 38 may also be exposed by puncturing the sealing film 351.

When assembling the aerosol-generating product 30, the aerosol-generating substrate 33 may be first filled into the container body 316, the sealing member 38 is assembled to the container cover 317, then the container cover 317 with the sealing member 38 is riveted onto the container body 316, and finally the sealing film 351 is attached. During use, the sealing film 351 is first torn off, and then the sealing member 38 is pushed downward into the container body 316 for normal use. The aerosol-generating substrate 33 is placed inside the container body 316, and becomes liquid after being heated, so that the aerosol-generating substrate 33 is not prone to flow out of the opening 311.

In a process of assembling the suction nozzle 10, the host 20, and the aerosol-generating product 30, the sealing member 38 may be pushed downward through an air guide tube 13 in the suction nozzle 10, to implement air inlet and air outlet of the aerosol-generating product 30. In this case, an outer diameter of the air guide tube 13 is less than an inner diameter of the opening 311, so that a vent gap for air flow is formed between an outer wall surface of the air guide tube 13 and an inner wall surface of the opening 311. One of the vent gap and the air guide channel 130 may be used for air inlet, and the other of the vent gap and the air guide channel 130 may be used for air outlet. It may be understood that in other embodiments, the sealing member 38 may be removed without passing through the air guide tube 13. In this case, the air guide tube 13 does not need to extend into the opening 311.

FIG. 22 and FIG. 23 show an aerosol-generating product 30 according to an eleventh embodiment of the present invention. In this embodiment, the container 31 only includes a container body 316, and an upper end of the container body 316 is open to form an opening 311. The container body 316 may be made of a ferromagnetic material, which may induce a magnetic field and generate heat. A sealing member 38 may switch from a first state in which the opening 311 is sealed to a second state in which the opening 311 is opened through deformation, for example, deformation by being heated.

In a first specific implementation, the sealing member 38 may be made of a hot melt material, which may be in a shape of a sheet or other shapes. The sealing member 38 may melt and fall into the container 31 after being heated.

In a second specific implementation, the sealing member 38 may be made of a shape memory material, and the sealing member 38 may change its shape after being heated, thereby disconnecting from the opening 311. A shape of the sealing member 38 in the first state and the second state is not limited, provided that the sealing member 38 may seal the opening 311 in the first state and open the opening 311 in the second state.

In a third specific implementation, the sealing member 38 may include a sealing body and a hot melt adhesive sealingly connecting a periphery of the sealing body and a periphery of the opening 311. A material of the sealing body may be not limited. The hot melt adhesive melts after being heated, causing the sealing body to detach from the opening 311 and fall into the container 31.

FIG. 24 shows an aerosol-generating product 30 according to a twelfth embodiment of the present invention. A difference between the twelfth embodiment and the eleventh embodiment is that when a sealing member 38 in this embodiment is in a second state, a part of the sealing member 38 is connected to an opening 311, and a part of the sealing member 38 is located in an accommodating cavity 310.

A manner in which the sealing member 38 switches from the first state to the second state may include a deformation manner or a rotation connection manner. For example, the sealing member 38 may be made of a shape memory material that may change shape and switch to the second state when heated. For another example, the sealing member 38 is rotatably connected to the opening 311, and may rotate to open the opening 311 in manners such as pressing.

FIG. 25 shows an aerosol-generating product 30 according to a thirteenth embodiment of the present invention. The aerosol-generating product 30 in this embodiment includes a container 31, a heating element 32, an aerosol-generating substrate 33, and a sealing film 351. An accommodating cavity 310 with an opening 311 at an end is formed in the container 31, and the aerosol-generating substrate 33 is arranged in the accommodating cavity 310 and may be in communication with the outside via the opening 311. Further, the container 31 includes a blocking portion 315 extending from at least a part of a periphery of the opening 311 into the accommodating cavity 310 and/or facing away from the accommodating cavity 310. The blocking portion 315 may be configured to block the aerosol-generating substrate 33 from flowing out of the opening 311 when the aerosol-generating product 30 is tilted or placed upside down. The heating element 32 is arranged in the accommodating cavity 310 and is at least partially in contact with the aerosol-generating substrate 33. The heating element 32 may induce a magnetic field in an electromagnetic environment to generate heat, and transfer the heat to the aerosol-generating substrate 33, thereby heating the aerosol-generating substrate 33.

In this embodiment, the container 31 may include a container side wall 312 in a shape of a tube, a container bottom wall 313 arranged at a lower end of the container side wall 312, a container top wall 314 arranged at an upper end of the container side wall 312, and a blocking portion 315 extending from the container top wall 314 toward the inside of the accommodating cavity 310. The container top wall 314 is in a shape of an annular plate, and an inner wall surface of the container top wall 314 defines an opening 311. A center line of the opening 311 may be parallel to or coincident with a center line of the accommodating cavity 310. The blocking portion 315 extends for a length from a periphery of the opening 311 into the accommodating cavity 310, and an inner wall surface of the blocking portion 315 defines a communication hole 3150 that is in communication with the opening 311.

In some embodiments, an outer diameter of the aerosol-generating product 30 may range from 10 mm to 12 mm, and the height may range from 10 mm to 12 mm. A minimum cross-sectional area of the communication hole 3150 may range from 2 mm² to 3.5 mm², or a minimum pore size of the communication hole 3150 may range from 1.5 mm to 2.1 mm. The height H of the blocking portion 315 may range from 1.5 mm to 3 mm, or the height H of the blocking portion 315 may range from ⅛ to 3/10 of the height of the aerosol-generating product 30. In the range, it may be ensured that the blocking portion 315 may better block leakage of the aerosol-generating substrate 33.

In this embodiment, a container top wall 314 is in a shape of a concentric ring and its center line coincides with a center line of the accommodating cavity 310. The blocking portion 315 is in a shape of a circular tube and extends vertically downward from an inner wall surface of the container top wall 314. The blocking portion 315 is perpendicular to the container top wall 314, and an inner diameter and an outer diameter of the blocking portion 315 remain unchanged in an axial direction of the blocking portion 315. The outer diameter of the blocking portion 315 is less than the inner diameter of the accommodating cavity 310, so that the outer wall surface of the blocking portion 315 is spaced apart from the inner wall surface of the container side wall 312. In addition, in this embodiment, the container 31 has an even wall thickness structure. In other words, the container side wall 312, the container bottom wall 313, the container top wall 314, and the blocking portion 315 that form the container 31 have the same or substantially the same thickness. In some embodiments, the wall thickness of the container 31 may range from 0.1 mm to 0.5 mm. In another embodiment, the container 31 may also have a non-even wall thickness structure.

It may be understood that in other embodiments, the blocking portion 315 may also have other structural shapes. For example, the blocking portion 315 and the container top wall 314 may also have an obtuse or an acute angle. For another example, the blocking portion 315 may also be in other shapes such as a shape of an elliptical tube, a square tube, and the like with a constant cross-sectional area from bottom to top, or may be in a tapered tube shape with a cross-sectional area that gradually increases or decreases from bottom to top. For another example, the blocking portion 315 may also have a non-closed structure in a shape of a tube. Specifically, one or more axially extending notches may be formed on the blocking portion 315.

A bottom surface (namely, a surface of the blocking portion 315 close to the container bottom wall 313) of the blocking portion 315 is spaced apart from a top surface (namely, a surface of the aerosol-generating substrate 33 away from the container bottom wall 313) of the aerosol-generating substrate 33. When the aerosol-generating substrate 33 is in the form of a paste, a liquid level when the aerosol-generating substrate 33 is heated and liquefied is lower than the bottom surface of the blocking portion 315. Through the foregoing design, no matter whether the aerosol-generating product 30 is placed upright, tilted, or upside down, the aerosol-generating substrate 33 is not prone to leak out of the opening 311, and the aerosol-generating substrate 33 is not prone to flow out of the opening 311 after being heated and liquefied.

For a structure of the heating element 32, refer to the foregoing embodiments. Specifically, in this embodiment, the heating element 32 is in a shape of a cylinder, and the cylindrical heating element 32 may be further used as a container to accommodate the aerosol-generating substrate 33. The aerosol-generating substrate 33 may be filled into the heating element 32 through the opening 311 and an upper end opening of the heating element 32. An outer diameter of the heating element 32 may be less than or equal to an inner diameter of the container side wall 312. It may be understood that in other embodiments, the heating element 32 may also not be arranged in the aerosol-generating product 30.

Further, in some embodiments, the aerosol-generating product 30 may further include a tear-off sealing film 351 attached to the container 31. When heating is required for use, the sealing film 351 may be first torn off, to expose the opening 311, and then the aerosol-generating product 30 may be assembled on the host 20.

The container 31 may be an integrally formed structure, and may be made of high temperature resistant materials such as glass, ceramics, metal, plastic, and the like. In this embodiment, the container 31 is a glass tube formed by sintering. When manufacturing the aerosol-generating product 30, the heating element 32 may be first placed inside a body of the container 31, and then sintered and formed, so that the heating element 32 and the container 31 form an integrated structure through sintering. Then, the aerosol-generating substrate 33 is filled into the container 31 through the opening 311, and finally the sealing film 351 is attached. Because the heating element 32 may be placed in the container 31 before the container 31 is sintered and formed, so that a size (such as the diameter, the length, or the width of a cross-sectional outer contour, and the like) of a cross-sectional outer contour of the heating element 32 may be greater than, less than, or equal to a size (such as the diameter, the length, or the width of the cross-sectional outer contour, and the like) of a cross-sectional outer contour of the opening 311. A size of the heating element 32 may be flexibly designed as required.

It may be understood that in other embodiments, the container 31 may also have a separate structure. For example, the container top wall 314 and the container side wall 312 are separately arranged, and/or the blocking portion 315 and the container top wall 314 are separately arranged.

FIG. 26 shows an aerosol-generating product 30 according to a fourteenth embodiment of the present invention. Similar to the thirteenth embodiment, the aerosol-generating product 30 in this embodiment is also in a shape of a cylinder and includes a container 31, a heating element 32, an aerosol-generating substrate 33, and a sealing film 351. A structure of the heating element 32 and a structure of the sealing film 351 are similar to the structure in the thirteenth embodiment. This is not repeated herein again.

Different from the thirteenth embodiment, a container top wall is not arranged on an upper end of the container 31 in this embodiment, and the upper end of the container side wall 312 is open to form an opening 311. Specifically, in this embodiment, the container 31 includes a container side wall 312 in a shape of a tube, a container bottom wall 313 arranged at a lower end of the container side wall 312, and a blocking portion 315 extending from an upper end periphery of the container side wall 312 toward the inside of the accommodating cavity 310.

The blocking portion 315 further has a tendency to shrink toward a center of the opening 311, so that a minimum cross-sectional area of the cross-sectional inner contour of the blocking portion 315 is less than a cross-sectional area of the opening 311. In this embodiment, a tube wall of the blocking portion 315 is arc-shaped, and an outer diameter and an inner diameter of the blocking portion 315 gradually decrease and shrink in an arc shape from an end close to the opening 311 to an end away from the opening 311.

FIG. 27 shows an aerosol-generating product 30 according to a fifteenth embodiment of the present invention. A main difference between the fifteenth embodiment and the fourteenth embodiment is that a blocking portion 315 in this embodiment includes a shrinking section 3151 extending from an upper end periphery of a container side wall 312 into an accommodating cavity 310 and an extending section 3152 extending from an end of a shrinking section 3151 away from an opening 311. The shrinking section 3151 is in a shape of a truncated cone, and an outer diameter and an inner diameter of the shrinking section 3151 gradually decrease from an end close to the opening 311 to an end away from the opening 311 and shrink in a shape of a straight line. The extending section 3152 is in a shape of a horizontally arranged annular plate, and extends inward in a radial direction for a distance from an end of the shrinking section 3151 away from the opening 311. In another embodiment, the extending section 3152 may also be obliquely arranged or vertically arranged.

FIG. 28 shows an aerosol-generating product 30 according to a sixteenth embodiment of the present invention. A main difference between the sixteenth embodiment and the thirteenth embodiment is that a container 31 in this embodiment has a split structure, and includes a container body 316 and a container cover 317 arranged on an upper end of the container body 316.

The container body 316 is in a shape of a cylinder with an upper end open, and includes a container bottom wall 313 and a container side wall 312 in a shape of a tube extending upward from a periphery of the container bottom wall 313. The container cover 317 may include a container top wall 314 covering an upper end of the container side wall 312 and a blocking portion 315 extending downward from an inner periphery of the container top wall 314. In addition, the blocking portion 315 may further include a first blocking section 3153 and a second blocking section 3154 extending from a lower end of the first blocking section 3153. An angle (including a right angle, an acute angle, and an obtuse angle) is formed between the first blocking section 3153 and the second blocking section 3154. Specifically, in this embodiment, the first blocking section 3153 is vertically arranged, and an inner diameter and an outer diameter of the first blocking section 3153 remain unchanged in an axial direction of the first blocking section 3153; and the second blocking section 3154 and a vertical direction are arranged in an angle. An inner diameter and an outer diameter of the second blocking section 3154 gradually decrease in an axial direction of the second blocking section 3154 away from a direction of the opening 311. Certainly, in another embodiment, the blocking portion 315 may also have a one-section structure, or may include three or more blocking sections.

The container body 316 and the container cover 317 may be made of different materials, or may be made of the same material. In an embodiment, the container body 316 is made of a ferromagnetic metal material, and may induce a magnetic field in a magnetic field and generate heat, thereby heating the aerosol-generating substrate 33 accommodated in the container body 316. The container cover 317 is made of a non-ferromagnetic metal material, thereby avoiding dry burning. In this case, a heating element does not need to be additionally arranged in the container 31.

In another embodiment, both the container body 316 and the container cover 317 are made of non-ferromagnetic materials, and the heating element is arranged in the container 31 to generate heat.

FIG. 29 shows an aerosol-generating product 30 according to a seventeenth embodiment of the present invention. A main difference between the seventeenth embodiment and the fourteenth embodiment is that a blocking portion 315 in this embodiment extends from a periphery of an opening 311 in a direction facing away from an accommodating cavity 310.

Similar to the fourteenth embodiment, in this embodiment, the blocking portion 315 also has a tendency to shrink toward a center of the opening 311, so that a minimum cross-sectional area of the cross-sectional inner contour of the blocking portion 315 is less than a cross-sectional area of the opening 311. Specifically, in this embodiment, the blocking portion 315 is in a shape of a tapered tube arranged coaxially with the opening 311 and the accommodating cavity 310, and the cross-sectional area of the blocking portion 315 gradually decreases in a direction away from the opening 311.

FIG. 30 shows an aerosol-generating product 30 according to an eighteenth embodiment of the present invention. A difference between the eighteenth embodiment and the seventeenth embodiment is that a blocking portion 315 in this embodiment extends from a part of an edge of the opening 311 in a direction facing away from the accommodating cavity 310.

Specifically, the blocking portion 315 may obliquely extend upward from an edge on one side of the opening 311 to the other side. Further, projection of the blocking portion 315 on the opening 311 in a vertical direction (or in an axial direction of the container 31) may block at least most of the opening 311, and a leakage prevention effect is better.

FIG. 31 shows an aerosol-generating product 30 according to a nineteenth embodiment of the present invention. A main difference between the nineteenth embodiment and the foregoing embodiment is that a blocking portion 315 in this embodiment includes an inner blocking portion 3155 extending from a part of a periphery of an opening 311 into an accommodating cavity 310 and an outer blocking portion 3156 extending from a part of a periphery of the opening 311 in a direction facing away from the accommodating cavity 310.

The inner blocking portion 3155 and the outer blocking portion 3156 may be separately formed by extending from edges on two opposite sides of the opening 311. Further, projection of the inner blocking portion 3155 on the opening 311 in a vertical direction partially overlaps with projection of the outer blocking portion 3156 on the opening 311 in a vertical direction, so that a leakage prevention effect is better.

It can be understood that the foregoing technical features can be used in any combination without limitation.
