Priority is claimed to Chinese Patent Application No. 202310592997.3, filed on May 24, 2023, the entire disclosure of which is hereby incorporated by reference herein.
The present invention relates to the field of vaporization technologies, and more specifically, to an aerosol-generation article and a vaporization device.
An aerosol is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in a gas medium. Because the aerosol may be absorbed by a human body through the respiratory system, a new alternative absorption method is provided for users. A vaporization device is a device that uses a stored vaporizable medium to form the aerosol in a heating or ultrasonic manner. The vaporizable medium includes a liquid, gel, pasty, or solid aerosol-generation substrate. The medium is vaporized, and the inhalable aerosol can be delivered to the user, to replace conventional product forms and absorption methods.
Before first-time use or after an aerosol-generation substrate is used up, the user is usually required to autonomously fill the aerosol-generation substrate, but this causes a filling amount and quality of the aerosol-generation substrate to be uncontrollable, or causes another vaporization particle during filling, affecting user experience.
In an embodiment, the present invention provides an aerosol-generation article, comprising: a container, an accommodating cavity being formed inside the container, the accommodating cavity being provided with an opening at one end thereof; and a heating element arranged in the accommodating cavity, wherein a heating cavity configured to accommodate an aerosol-generation substrate is formed inside the heating element.
Subject matter of the present disclosure will be described in even greater detail below based on the exemplary figures. All features described and/or illustrated herein can be used alone or combined in different combinations. The features and advantages of various embodiments will become apparent by reading the following detailed description with reference to the attached drawings, which illustrate the following:

The aerosol-generation substrate 33 may include one or more of nicotine, nicotine base, nicotine salt, a nicotine derivative, and nicotine analogue. The nicotine salt may be selected from a list formed by the following components: nicotine citrate, nicotine lactate, nicotine pyruvate, nicotine bitartrate, nicotine pectate, nicotine alginate, and nicotine salicylate.
The aerosol-generation substrate 33 may include an aerosol-forming agent. The term “aerosol-forming agent” is used for describing any suitable known compound or mixture of compounds, and the aerosol-forming agent helps to promote and stabilize formation of an aerosol in use and is substantially resistant to thermal degradation at the operating temperature of the aerosol-generation article 30. A suitable aerosol-forming agent includes, but not limited to, polyol such as triethylene glycol, 1,3butylene glycol, and glycerol; ester of polyol such as monoglyceride and diacetate or triacetate; and fatty acid ester of monocarboxylic acid, or dicarboxylic acid, or polybasic carboxylic acid such as dimethyl dodecanedioate and dimethyl tetradecanedioate. Preferably, the aerosol-forming agent is polyol or a mixture of polyol, for example, triethylene glycol, 1,3butylene glycol, and glycerol.
The aerosol-generation substrate 33 may further include a perfume. The perfume may include a volatile flavor component. In some embodiments, the perfume may include menthol. The term “menthol” is used for indicating an isomer of a compound 2-isopropyl-5-methylcyclohexanol in any form. The perfume may provide flavors selected from menthol, lemon, vanilla, orange, holly, cherry, and cinnamon. The perfume may include a volatile tobacco perfume compound released from the substrate during heating.
The aerosol-generation substrate 33 may further include tobacco or a tobacco-containing material. For example, the aerosol-generation substrate 33 may include any of the following: tobacco leaves, tobacco leaf vein segments, reconstituted tobacco, homogenized tobacco, extruded tobacco, tobacco slurry, cast leaf tobacco, and expanded tobacco. Optionally, the aerosol-generation substrate 33 may include tobacco powder compressed by using, for example, glass or ceramic or another suitable inert material. In a case that the aerosol-generation substrate 33 includes liquid or gel, in some embodiments, the aerosol-generation article 30 may include an adsorbent carrier. The aerosol-generation substrate 33 may be coated on or impregnated into the adsorbent carrier. For example, a nicotine compound and the aerosol-forming agent may be combined with water as a liquid preparation. In some embodiments, the liquid preparation may further include a perfume. Such liquid preparation may then be absorbed by the adsorbent carrier or coated on a surface of the adsorbent carrier. The adsorbent carrier may be a sheet or a tablet of a cellulose-based material onto which the nicotine compound and the aerosol-forming agent may be coated or absorbed.
When including solid, the aerosol-generation substrate 33 may include solid in one or more forms of pulverized, granulated, powdered, granular, stripe, sheet, or the like. When including a plant-like material, the aerosol-generation 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 engaged with each other. The suction nozzle 10 is detachably arranged on one end of the host 20, and an output channel 11 is formed in the suction nozzle 10. The aerosol-generation article 30 is engaged between the suction nozzle 10 and the host 20 and is in communication with the output channel 11. The host 20 can generate energy after being energized to heat the aerosol-generation substrate 33 stored in the aerosol-generation article 30. An aerosol generated by heating the aerosol-generation substrate 33 can flow out through the output channel 11 for a user to use.
In some embodiments, the suction nozzle 10, the host 20, and the aerosol-generation article 30 are detachably combined together. The aerosol-generation article 30 is pre-loaded with the aerosol-generation substrate 33, and after the aerosol-generation substrate 33 in the aerosol-generation article 30 is used up, the aerosol-generation article 30 can be replaced to update the aerosol-generation substrate 33, so that a use amount of the aerosol-generation substrate 33 can be accurately controlled, quality of the aerosol-generation substrate 33 is ensured, and introduction of other impurities in a process of manually adding the aerosol-generation substrate 33 is avoided. In addition, the suction nozzle 10 and the host 20 can be reused, so that use costs of the vaporization device 100 are reduced. Certainly, after the aerosol-generation substrate 33 in the aerosol-generation article 30 is used up, the aerosol-generation substrate 33 may alternatively be filled into the aerosol-generation article 30 by using a known filling device/method.
In some embodiments, one end of the aerosol-generation article 30 may be inserted into the host 20, and the other end is docked with the suction nozzle 10. A vaporization cavity 240 for accommodating the aerosol-generation article 30 may be formed on one end of the host 20 engaged with the suction nozzle 10, one end of the vaporization cavity 240 close to the suction nozzle 10 is provided with an insertion hole 244, one end of the aerosol-generation article 30 may be inserted into the vaporization cavity 240 through the insertion hole 244, and the other end of the aerosol-generation article 30 may extend out of the vaporization cavity 240 and is engaged with the suction nozzle 10. In another embodiment, the other end of the aerosol-generation article 30 may alternatively not extend out of the vaporization cavity 240, that is, the aerosol-generation article 30 may alternatively be completely accommodated in the vaporization cavity 240.
The host 20 may be connected to the suction nozzle 10 through magnetic attraction, so that it is easier to assemble and disassemble the host 20 and the suction nozzle 10. Specifically, the end of the host 20 engaged with the suction nozzle 10 is provided with a support portion 211, and the vaporization cavity 240 may be formed in 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 a material 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 attraction material that can be absorbed by a magnet, and the host 20 is in a magnetic attraction connection with the suction nozzle 10 through the magnetic attraction member 26. Correspondingly, at least one magnetic attraction member 16 may be arranged on one end of the suction nozzle 10 engaged with the host 20, and the at least one magnetic attraction member 16 magnetically attracts and matches 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 lateral sides of the support portion 211. 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 another embodiment, the support portion 211 may alternatively be made of a magnetic metallic material, so that there may be no need to arrange the magnetic attraction member 26. In some other embodiments, the host 20 may alternatively be connected to the suction nozzle 10 in another detachable manner such as threaded connection or buckle connection. 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 is of a columnar structure, and a shape of a cross section of the housing may be various shapes such as a racetrack, an ellipse, a circle, and a square. This is not limited herein. The circuit board 23 is respectively electrically connected to the battery 22 and the heating assembly 24, and a control chip and a related control circuit are arranged on the circuit board 23 and configured to implement calculation and control of 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-generation article 30 and is configured to heat the aerosol-generation substrate 33 in the aerosol-generation article 30 after being energized.
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 alternatively be arranged in the housing 21 in another manner, for example, the battery 22 and the circuit board 23 may alternatively be arranged side by side.
In this embodiment, the host 20 heats the aerosol-generation substrate 33 through electromagnetic induction. The heating assembly 24 includes an inductive heating source 242. The inductive heating source 242 is electrically connected to the battery 22 and can generate a fluctuating electromagnetic field after being energized, to heat a susceptor located in the fluctuating electromagnetic field.
In this embodiment, the heating assembly 24 is tubular, and the vaporization cavity 240 is formed in the heating assembly 24. The inductive heating source 242 may include an induction coil 2421, and the induction coil 2421 may be wound around the outside of the vaporization cavity 240. Further, the heating assembly 24 may include a support 241 and a magnetic shielding member 243 sleeved outside the induction coil 2421. The support 241 is configured to form the vaporization cavity 240 and may be configured to mount and fix the induction coil 2421. The magnetic shielding member 243 can reduce electromagnetic radiated from the induction coil 2421 to the outside and can be configured to fix the induction coil 2421.
The aerosol-generation article 30 is designed to be engaged with the host 20 that includes an electrical operation of the inductive heating source 242. The aerosol-generation article 30 includes a susceptor. The susceptor may be coupled to the inductive heating source 242 and interacts with the inductive heating source 242. The term “susceptor” is used for describing a material that can convert electromagnetic energy into heat. When the susceptor is located in the fluctuating electromagnetic field, the fluctuating electromagnetic field may generate an eddy current in the susceptor, and the eddy current may heat the susceptor through ohmic or resistive heating, to heat the aerosol-generation substrate 33. In a case that the susceptor includes a ferromagnetic material (for example, iron, nickel, or cobalt), the susceptor may be further heated due to a hysteresis loss.
The susceptor may be formed by any material that can be inductively heated sufficiently to cause the aerosol-generation substrate 33 to generate an aerosol. A suitable susceptor material may include one or more of graphite, molybdenum, silicon carbide, stainless steel, niobium, aluminum, nickel, nickel containing compound, titanium, and metallic material composite. Preferably, the susceptor includes a metal or carbon. Further, the susceptor may include a ferromagnetic material or is formed by a ferromagnetic material. The ferromagnetic material may include ferritic iron, ferromagnetic alloy (for example, ferromagnetic steel or stainless steel), or ferromagnetic particle or ferrite. In some embodiments, the susceptor may be formed by 400 series of stainless steel, for example, 410 stainless steel, 420 stainless steel, or 430 stainless steel.
It may be understood that in some other embodiments, the heating assembly 24 and the aerosol-generation article 30 may alternatively be heated in another heating manner such as heat conduction, infrared radiation, ultrasonic, microwave, and plasma.
In some other embodiments, the aerosol-generation article 30 and the suction nozzle 10 may alternatively be an integral structure. The aerosol-generation article 30 and the suction nozzle 10 that are integrated detachably match the host 20, thereby eliminating a problem of cleaning the suction nozzle 10. Because the host 20 can 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, replacement costs can also be reduced.
In still another embodiment, the suction nozzle 10 may alternatively be rotatably or slidably mounted on the host 20, the aerosol-generation article 30 is detachably engaged between the suction nozzle 10 and the host 20, the aerosol-generation article 30 is covered or exposed by rotating or sliding the suction nozzle 10, and the aerosol-generation article 30 can also be updated.
The container 31 may be made of a high-temperature resistant material such as glass, ceramic, metal, plastic, or aluminum foil. Further, at least a part of the container 31 may be made of a transparent material. The term “transparent” is used for describing a material that allows at least a significant proportion of incident light to pass through, so that the material can be seen through. In the present invention, the substantially transparent material may allow sufficient light to pass through, so that the aerosol-generation substrate 33 in the accommodating cavity 310 is visible before being vaporized. In a case that the aerosol-generation substrate 33 in the accommodating cavity 310 may also be transparent, the substantially transparent material may also allow smoke or one or more other aerosols generated by the aerosol-generation substrate 33 to be visible during inhalation of the aerosol-generation article 30.
The container 31 may be completely transparent. Alternatively, the container 31 may have a relatively low degree of transparency while still transmitting sufficient light to allow the aerosol-generation substrate 33 in the accommodating cavity 310 to be visible before being vaporized, or to allow smoke or one or more other aerosols generated by the aerosol-generation substrate 33 to be visible.
Further, the container 31 may include one or more regions formed by the transparent material, so that a part of the aerosol-generation substrate 33 is visible through the one or more regions. In addition, the region formed by the transparent material may be in color, colored, or colorless.
In this embodiment, the container 31 is a cylindrical glass tube and may include a tubular container side wall 312 and a container bottom wall 313 arranged on one end of the container side wall 312. The container side wall 312 and the container bottom wall 313 jointly define the accommodating cavity 310 provided with an opening 311 at one end. The heating element 32 and the aerosol-generation substrate 33 may be mounted in the accommodating cavity 310 through the opening 311. The container bottom wall 313 may be configured to support the heating element 32 and the aerosol-generation substrate 33.
The heating element 32 may include a ferromagnetic material or is made of a ferromagnetic material. The heating element 32 may be arranged in the container 31. The heating element 32 can be in direct contact with the aerosol-generation substrate 33, and heat generated by the heating element 32 can be directly transferred to the aerosol-generation substrate 33, thereby improving heat transfer efficiency. In addition, the container 31 can function in heat insulation to reduce heat transferred from the heating element 32 to the outside.
In some embodiments, a heating cavity 320 may be formed in the heating element 32, and the aerosol-generation substrate 33 is accommodated in the heating cavity 320. Specifically, in this embodiment, the heating element 32 is a cylindrical metal cylinder and may include a tubular heating side wall 321 and a heating end wall 322 arranged on one end of the heating side wall 321. The heating side wall 321 and the heating end wall 322 jointly define the heating cavity 320. The heating end wall 322 may be supported on the container bottom wall 313, an opening 323 is formed on one end of the heating element 32 opposite to the heating end wall 322, and the aerosol-generation substrate 33 may be filled into the heating cavity 320 through the opening 323 and supported on heating end wall 322. During assembly, the aerosol-generation substrate 33 may be first filled into the heating element 32, and then the aerosol-generation substrate and the heating element are placed into the container 31 together. Alternatively, the heating element 32 may be first placed into the container 31, and then the aerosol-generation 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, so that the heating element 32 is more easily assembled into the container 31, and a gap 3210 is formed between an outer surface of the heating side wall 321 and an inner surface of the container side wall 312, to facilitate heat insulation and reduce 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 having a capillary force and is configured for a liquid aerosol-generation substrate 33 after the aerosol-generation substrate 33 is liquefied during heating to enter the gap 3210 through a through hole 3220 provided on the heating element 32, so that another defect affecting a vaporization effect such as excessively high temperature between the heating side wall 321 of the heating element 32 and the container 31 to produce odor can be avoided. It may be understood that in another embodiment, the gap 3210 may alternatively be a non-capillary structure, or a partial region is a non-capillary structure, and a partial region is a capillary structure.
There may be one or more through holes 3220, and the through hole 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 hole diameter of the through hole 3220 may range from 0.5 mm to 1.5 mm. In this range, a pasty aerosol-generation substrate 33 can be prevented from flowing out from the through hole 3220, and a liquefied aerosol-generation substrate 33 can flow out from the through hole 3220. Certainly, in another embodiment, the through hole 3220 may alternatively not be provided on the heating element 32.
In another embodiment, an outer wall surface of the heating side wall 321 may be in transition fit with or in interference fit with, or partially in clearance fit with, or partially in interference fit with an inner wall surface of the container side wall 312.
It may be understood that in another embodiment, the heating element 32 is not limited be cylindrical, for example, the heating element 32 may alternatively be tubular and is not provided with the heating end wall 322, or may be in another shape of a U-shaped sheet. In addition, in some other embodiments, the heating element 32 may alternatively be arranged on an outer side of the container 31.
In some embodiments, an isolating layer may be further arranged on an inner surface of the heating element 32, and the isolating layer may include a ceramic glaze layer or a glass glaze layer. The heating element 32 is isolated from the aerosol-generation substrate 33 through the isolating layer, and odor that may be generated during heating can be further avoided. The through hole 3220 provided on the heating element 32 can also make it easier for the inner surface of the heating element 32 to be coated with a glaze layer during glaze plating, thereby ensuring that the heating element 32 is evenly coated with the glaze layer.
Further, in some embodiments, the aerosol-generation article 30 further includes a scaling assembly 35. The sealing assembly 35 is arranged at the opening 311 of the container 31 and is configured to seal the opening 311, to prevent the aerosol-generation substrate 33 in the container 31 from flowing out and prevent an external impurity from entering the container 31. In this embodiment, the scaling assembly 35 includes a sealing film 351, and the scaling film 351 may be attached to a periphery of the opening 311 to seal the opening 311. During use, the sealing film 351 may be first stripped off to expose the opening 311, and then the aerosol-generation article 30 is assembled to the host 20. The sealing film 351 may include a body portion 3511 for scaling the opening 311 and a protruding portion 3512 extending from an edge of the body portion 3511 to the outside, and a user may tear off the sealing film 351 by gripping the protruding portion 3512. In another embodiment, the opening 311 may alternatively be exposed by piercing the sealing film 351.
In another embodiment, the sealing assembly 35 may also include another scaling structure, for example, the sealing assembly 35 may include a thin wall structure that can be pierced, or may include a sealing plug plugged into the opening 311, or may include a sealing cover that covers the opening 311.
In some embodiments, the aerosol-generation article 30 may further include a limiting member 34 arranged in the container 31. The limiting member 34 is arranged between the sealing assembly 35 and the aerosol-generation substrate 33 and is configured to prevent the aerosol-generation substrate 33 from flowing to the sealing assembly 35 to cause a waste. The limiting member 34 may be made of a high-temperature resistant material such as metal or non-metal. Further, the limiting member 34 may be made of a material that cannot generate heat due to induction of a magnetic field, which can prevent dry burning of the limiting member 34 due to the fact that the aerosol-generation substrate 33 becomes small during heating and is not in contact with the limiting member 34. In another embodiment, the limiting member 34 may alternatively be made of a metal material that can generate heat due to induction of a magnetic field.
The limiting member 34 may be arranged outside the heating element 32 or in the heating element 32, and/or the limiting member 34 may be arranged integrally or separately from the heating element 32. In this embodiment, the limiting member 34 includes a mesh sheet 341, the mesh sheet 341 may be a metal mesh sheet, and the metal mesh sheet has the advantages of high temperature resistance, no pollution, no odor, and low cost. A plurality of mesh holes 3410 are formed on the mesh sheet 341, and a hole diameter of the mesh hole 3410 is within an appropriate range, which can allow an air flow to pass through and can prevent the aerosol-generation substrate 33 from flowing out from the mesh hole 3410. In addition, when the aerosol-generation substrate 33 is heated, the mesh sheet 341 can further prevent the aerosol-generation substrate 33 from sputtering outward. In another embodiment, the limiting member 34 may also include a hot melt film. After being heated, the hot melt film can automatically rupture or be burnt, and is non-toxic, odorless, and pollution-free.
In this embodiment, the mesh sheet 341 is arranged outside the heating element 32 and abuts against an edge of the opening 323. At least a part of an outer wall surface of the mesh sheet 341 is in interference fit with an inner wall surface of the container 31, and the mesh sheet 341 is fixed in the container 31 through interference fit. In some embodiments, the mesh sheet 341 may include a sheet body 3411 and a plurality of limiting flanges 3412 extending from an outer edge of the sheet body 3411 to the outside. The plurality of mesh holes 3410 may be arranged on the sheet body 3411 in an array, and the plurality of limiting flanges 3412 may be distributed at uniform intervals in a circumferential direction of the sheet body 3411. An outer diameter of the sheet 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, thereby facilitating mounting.
As shown in
In some embodiments, the air inlet channel 12 may include at least one first air inlet passage 121 in communication with the outside and at least one second air inlet passage 122 that allows the at least one first air inlet passage 121 to be in communication with the accommodating cavity 310. Specifically, in this embodiment, there are two first air inlet passages 121, and the two first air inlet passages 121 extend in a horizontal direction and are respectively located on two opposite sides of the suction nozzle 10. There is one second air inlet passage 122. The one second air inlet passage 122 extends in a longitudinal direction and may be coaxially arranged with the accommodating cavity 310, and two ends of the second air inlet passage 122 in the longitudinal direction are respectively in communication with the first air inlet passage 121 and the accommodating cavity 310.
In some embodiments, the suction nozzle 10 may include an air guide pipe 120 extending in a longitudinal direction, and an inner wall surface of the air guide pipe 120 defines the second air inlet passage 122. The air guide pipe 120 may be made of a high-temperature resistant material such as metal and high-temperature resistant plastic (for example, polyetheretherketone). The air guide pipe 120 may extend into the accommodating cavity 310 and may be coaxially arranged with the accommodating cavity 310, and one end of the air guide pipe 120 extending into the accommodating cavity 310 is spaced apart from the mesh sheet 341. An outer diameter of the air guide pipe 120 is less than an inner diameter of the container 31, so that an annular channel 111 is formed between an outer wall surface of the air guide pipe 120 and an inner wall surface of the container 31, and the annular channel 111 may be configured to form a part of the output channel 11.
A top surface of the suction nozzle 10 extends downward in a longitudinal direction and forms an exhaust channel 113 that allows the annular channel 111 to be in communication with the outside. In some embodiments, at least one communication channel 112 that allows the annular channel 111 to be in communication with the exhaust channel 113 is further formed in the suction nozzle 10, and the annular channel 111, the at least one communication channel 112, and the exhaust channel 113 are sequentially in communication with each other from bottom to top to form the output channel 11. In this embodiment, there are two communication channels 112, and the two communication channels 112 are respectively located on two outer sides at an upper end of the air guide pipe 120.
In some embodiments, the vaporization device 100 may further include a temperature sensor 14 electrically connected to the circuit board 23. At least a part of the temperature sensor 14 is arranged in the output channel 11 and is configured to detect a temperature of an air flow in the output channel 11 and transmit the temperature data to the circuit board 23. A related control circuit is arranged on the circuit board 23 and can control a heating power of the heating assembly 24 according to the temperature data. In this embodiment, the temperature sensor 14 is a thermocouple and may be arranged on one end of the exhaust channel 113 close to the communication channel 112. In another embodiment, the temperature sensor 14 may alternatively adopt another sensor structure such as a thermistor, and/or the temperature sensor 14 may be arranged at another position of the output channel 11.
Further, the suction nozzle 10 further includes two first electrodes 15 electrically connected to the temperature sensor 14. The host 20 further includes two second electrodes 25 electrically connected to the circuit board 23. The two first electrodes 15 are respectively connected to the two second electrodes 25 through contact conduction, so that the temperature sensor 14 is electrically connected to the circuit board 23. In this embodiment, both the first electrode 15 and the second electrode 25 are electrode columns, and the first electrode 15 and/or the second electrode 25 is elastic, to improve reliability of electrical connection. In another embodiment, the first electrode 15 and/or the second electrode 25 may also include another conductive connection structure such as a conductive elastic sheet.
Different from the aerosol-generation article 30 in the first embodiment, the container 31 in this embodiment is an aluminum foil paper tube having openings on two ends. Because the container 31 in this embodiment does not have a container bottom wall 313 that can function in support, at least a part of an outer wall surface of the heating element 32 is in interference fit with an inner wall surface of the container 31, and 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 part of the outer wall surface of the heating element 32 is in interference fit with the inner wall surface of the container 31, and a part of the outer wall surface of the heating element is in clearance fit with the inner wall surface of the container 31.
The heating element 32 is a metal cylinder and includes a tubular heating side wall 321 and a heating end wall 322 arranged on one end of the heating side wall 321. In some embodiments, the heating side wall 321 may include a first side wall 3211 close to one end of the heating end wall 322 and a second side wall 3212 away from the end of the heating end 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 in interference fit with an inner peripheral surface of the container 31, so that the heating element 32 is fixed in the container 31.
According to a second aspect, an outer peripheral surface of the first side wall 3211 is in clearance fit with the inner peripheral surface of the container 31, so that the heat transferred from the heating element 32 to the container 31 can be reduced, to avoid burning the paper tube. According to a third aspect, the aerosol-generation substrate 33 is mainly arranged in the first side wall 3211 close to the heating end wall 322, the first side wall 3211 is a main heating region, and setting the first side wall 3211 to be in clearance fit with the container 31 and the second side wall 3212 to be in interference fit with the container 31 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 end surface of an opening end of the heating element 32, and an outer peripheral surface of the mesh sheet 341 is in interference fit with the inner peripheral surface of the container 31, so that the mesh sheet 341 is fixed in the container 31.
A structure of the sealing film 351 is similar to the structure in the first embodiment. Details are not described herein again.
Similar to the first embodiment, the heating element 32 in this embodiment is also a metal cylinder and includes a tubular heating side wall 321 and a heating end wall 322 arranged on one end of the heating side wall 321. Different from the first embodiment, in this embodiment, at least one protrusion 324 protrudes and is formed on the heating end wall 322, and the heating end wall 322 is supported on a container bottom wall 313 of the container 31 through the at least one protrusion 324, so that a direct contact area between the heating end wall 322 and the container bottom wall 313 can be reduced, and the heat transferred from the heating element 32 to the container 31 can be reduced.
In addition, different from the first embodiment, in this embodiment, the sealing assembly 35 includes a sealing plug 352, and the sealing plug 352 is detachably plugged in 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 silica gel and may include a sealing portion 3522 arranged in the opening 311 in a sealing manner. The sealing plug 352 may further include an exposed portion 3521 and an abutting portion 3523 that respectively extend from two ends of the sealing portion 3522 to the outside. The exposed portion 3521 is exposed outside the opening 311 to facilitate the user to pull out the sealing plug 352. The abutting portion 3523 is arranged in the container 31, and one end of the abutting portion 3523 away from the sealing portion 3522 may abut against the mesh sheet 341, to press the mesh sheet 341 and the heating element 32 on the container bottom wall 313. An outer diameter of the abutting portion 3523 may be less than an inner diameter of the container 31, so that a force required for assembling the sealing plug 352 into the container 31 can be reduced.
It may be understood that in another embodiment, the sealing plug 352 may alternatively be non-detachably connected to the container 31. In this case, a vent hole for an air flow to flow may be provided on the scaling plug 352.
The mesh sheet 341 may include a sheet body 3411 and a plurality of limiting flanges 3412 extending from an outer edge of the sheet body 3411 to the outside. A plurality of mesh holes 3410 may be provided on the sheet body 3411, and the plurality of limiting flanges 3412 may be distributed at uniform intervals in a circumferential direction of the sheet body 3411.
The heating element 32 is a metal cylinder and includes a tubular heating side wall 321 and a heating end wall 322 arranged on one end of the heating side wall 321. At least one protrusion 324 protrudes and is formed on an outer surface of the heating end wall 322, and the heating end wall 322 abuts against a container bottom wall 313 of the container 31 through the at least one protrusion 324, so that a direct contact area between the heating end wall 322 and the container bottom wall 313 can be reduced, and the heat transferred from the heating element 32 to the container 31 can be reduced.
In some embodiments, the heating side wall 321 may include a first side wall 3211 close to one end of the heating end wall 322 and a second side wall 3212 away from the end of the heating end wall 322. An outer diameter of the second side wall 3212 is greater than an outer diameter of the first side wall 3211, and an outer peripheral surface of the first side wall 3211 is in clearance fit with an inner peripheral surface of the container 31, so that the heat transferred from the heating element 32 to the container 31 can be reduced.
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 of the second side wall 3212 and the first side wall 3211 on an inner side, and the mesh sheet 341 may be arranged in the second side wall 3212 and abuts against the step surface 3213. Further, in some embodiments, a plurality of grooves 3214 respectively corresponding to the plurality of limiting flanges 3412 may be further formed on the second side wall 3212, and the plurality of limiting flanges 3412 may be respectively engaged in the plurality of grooves 3214, so that the mesh sheet 341 is fixed in the second side wall 3212.
The heating element 32 may be circumferentially fixed in the container 31 through interference fit between the limiting flange 3412 and a container side wall 312 or through interference fit between the second side wall 3212 and the container side wall 312.
In this embodiment, the heating element 32 is a metal cylinder and is invertedly mounted in the container 31. Specifically, the heating element 32 includes a tubular heating side wall 321 and a heating end wall 322 arranged on one end of the heating side wall 321. The heating end wall 322 is located on one end of the heating side wall 321 away from the container bottom wall 313. At least one vent hole 3221 for an air flow to flow is further provided on the heating end wall 322, so that external air can enter the heating element 32 and then carries an aerosol generated by vaporization of the aerosol-generation substrate 33 in the heating element 32 and flows out. Further, a plurality of vent holes 3221 that are uniformly arranged in an array may be provided on the heating end wall 322. A hole diameter of each vent hole 3221 is within an appropriate range, which can prevent the aerosol-generation substrate 33 from flowing out from the vent hole 3221.
An opening 323 is formed on one end of the heating side wall 321 opposite to the heating end wall 322. When the aerosol-generation substrate 33 is injected into the heating element 32, the heating end wall 322 of the heating element 32 is placed downward, and then the aerosol-generation substrate 33 is injected into the heating element 32 through the opening 323 by using an injection device. Because the hole diameter of the vent hole 3221 is relatively small and the aerosol-generation substrate 33 has a specific viscosity when being pasty, the aerosol-generation substrate 33 does not flow out easily from the vent hole 3221.
After the aerosol-generation substrate 33 is injected into the heating element 32, the heating element 32 is invertedly mounted in the container 31 again, so that the opening 323 of the heating element 32 faces the container bottom wall 313, and the heating end wall 322 is away from the container bottom wall 313.
It may be understood that in this embodiment, the heating end wall 322 can serve as the mesh sheet 341 in the foregoing embodiment, so that the aerosol-generation article 30 in this embodiment does not need to be provided with an additional mesh sheet 341, thereby reducing the costs.
It may be understood that the foregoing technical features can be used in any combination without limitation.
While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive. It will be understood that changes and modifications may be made by those of ordinary skill within the scope of the following claims. In particular, the present invention covers further embodiments with any combination of features from different embodiments described above and below. Additionally, statements made herein characterizing the invention refer to an embodiment of the invention and not necessarily all embodiments.
The terms used in the claims should be construed to have the broadest reasonable interpretation consistent with the foregoing description. For example, the use of the article “a” or “the” in introducing an element should not be interpreted as being exclusive of a plurality of elements. Likewise, the recitation of “or” should be interpreted as being inclusive, such that the recitation of “A or B” is not exclusive of “A and B,” unless it is clear from the context or the foregoing description that only one of A and B is intended. Further, the recitation of “at least one of A, B and C” should be interpreted as one or more of a group of elements consisting of A, B and C, and should not be interpreted as requiring at least one of each of the listed elements A, B and C, regardless of whether A, B and C are related as categories or otherwise. Moreover, the recitation of “A, B and/or C” or “at least one of A, B or C” should be interpreted as including any singular entity from the listed elements, e.g., A, any subset from the listed elements, e.g., A and B, or the entire list of elements A, B and C.
