Description

Technical Field

[0001] The present application belongs to the field of novel tobacco, and specifically relates to an aerosol generating product. Background Art

[0002] Aerosol-generating products are a new type of tobacco product used in conjunction with a heating device. Unlike traditional cigarettes that produce smoke through combustion, aerosol-generating products heat the aerosol-generating matrix in the aerosol-generating product through a heating device (usually around 350°C) to release nicotine and other ingredients to meet the consumer's smoking experience. The aerosol-generating matrix in aerosol-generating products usually contains tobacco, propylene glycol, glycerol, flavoring substances and other adhesives. Its structure generally includes a tobacco segment, a hollow fiber bundle segment, a cooling segment and a solid fiber bundle segment, which vary according to their functions.

[0003] When existing heated cigarettes are used with heating devices, the inhalation path of the aerosol generating product is generally from the solid fiber bundle of the matrix section directly to the filter section, and the generated aerosol is cooled by the hollow fiber bundle section and the cooling section in the middle. However, in some scenarios, it is necessary to change the aerosol flow path in the generating product to cooperate with the relevant heating device to achieve the best inhalation effect. Summary of the invention

[0004] In view of this, the purpose of this application is to provide an aerosol generating product to solve the above problems.

[0005] In order to solve the above technical problems, this application adopts the following technical solutions:

[0006] The present application provides an aerosol generating product, which includes: a filter segment and a substrate segment, wherein the filter segment is located at the proximal end of the aerosol generating product, the substrate segment is located at the distal end of the aerosol generating product, the substrate segment is provided with a first smoke outlet at the distal end, the substrate segment is placed in a heating chamber of an aerosol generating device for heating to generate aerosol and flow out from the first smoke outlet, a sealing partition is provided between the filter segment and the substrate segment, the sealing partition is used to prevent the aerosol from flowing directly from the substrate segment to the filter segment; the filter segment is provided with a breathable segment at a position close to the sealing partition.

[0007] Furthermore, the sealing baffle is made of a flexible material, is arranged around the matrix segment, and seals the proximal end of the matrix segment.

[0008] Furthermore, the flexible material is aluminum foil.

[0009] Furthermore, the sealing baffle is made of a rigid material, and is fixedly arranged at the connection between the filter segment and the matrix segment. The sealing baffle is adhesively arranged at the connection and seals the proximal end of the matrix segment.

[0010] Further, the rigid material is ceramic, polyetheretherketone or glass fiber.

[0011] Further, the thickness of the sealing partition is less than or equal to 5 mm.

[0012] Further, an air inlet is provided on the surface of the breathable section, and the air inlet surrounds the breathable section.

[0013] Further, the air inlet includes a plurality of ventilation holes, and the ventilation holes are circular ventilation holes and / or polygonal ventilation holes.

[0014] Further, the breathable section and the filter section are integrally formed.

[0015] Further, the aerosol-generating article is for a liquid-filtering smoking device.

[0016] Wherein, the aerosol-generating article is a smoking article, including an aerosol-forming substrate, which generates an aerosol that can be directly inhaled into the user's lungs through the user's mouth by heating. Preferably, the aerosol-forming substrate is a solid aerosol-forming substrate. The aerosol-forming substrate may simultaneously include solid and liquid components. Preferably, the aerosol-forming substrate includes nicotine. In some preferred embodiments, the aerosol-forming substrate includes tobacco.

[0017] It can be understood that tobacco itself has a unique flavor and aroma, which are key features pursued by many aerosol-generating articles. By extracting the effective components in tobacco and using them as part of the aerosol-forming substrate, the smoking experience of traditional tobacco products can be simulated. Nicotine is the main alkaloid in tobacco and is also an ingredient pursued by many smokers. Adding tobacco extract to the aerosol-forming substrate can ensure that the product contains an appropriate amount of nicotine to meet the needs of users.

[0018] An aerosol-generating device is a device for interacting with the aerosol-forming substrate of an aerosol-generating article to generate an aerosol. Preferably, the aerosol-generating device is a heating smoking device, which interacts with the aerosol-forming substrate of the aerosol-generating article to generate an aerosol that can be directly inhaled into the user's lungs through the user's mouth. The aerosol-generating device can be a holder for a smoking article.

[0019] The power source can be any suitable power source, such as a direct current voltage source, such as a battery. In one embodiment, the power source is a lithium-ion battery. Alternatively, the power source can be a nickel-metal hydride battery, a nickel-cadmium battery or a lithium-based battery, such as a lithium cobalt, lithium iron phosphate, lithium titanate or lithium polymer battery.

[0020] The control element can be a simple switch. Alternatively, the control element can be a circuit and can include one or more microprocessors or microcontrollers.

[0021] An aerosol generating system may include an aerosol generating device and one or more aerosol generating articles, and the aerosol generating device is configured to accommodate the aerosol generating articles in a corresponding number of heating chambers.

[0022] The heater can be an internal heater for insertion into the aerosol generating article, an external heater located on the outer periphery of the aerosol generating article, or a heater combining both internal and external ones; however, it is not limited thereto, as long as it can be used to heat the aerosol generating article to generate aerosol for inhalation.

[0023] As can be seen from the above technical solutions, the advantages and positive effects of the aerosol generating device, aerosol generating article, and aerosol generating system proposed in this application are as follows:

[0024] Compared with the traditional structural design in which the matrix section and the filter section of the aerosol generating article on the current market are directly connected, this application innovatively adds a sealing partition between the matrix section and the filter section of the aerosol generating article to ensure that the high-temperature aerosol does not directly flow from the matrix section to the filter section inside the article, but uses the breathable section to optimize the aerosol flow path. Specifically, the aerosol is first released from the matrix section into the external space of the article, and then is re-inhaled into the article through the air inlet on the breathable section. This process significantly extends the aerosol flow path, effectively reduces the temperature of the aerosol, and in combination with a liquid filtration type heating smoking device, can enhance its filtering effect on harmful substances in the aerosol.

[0058] The detailed features and advantages of the present application are described in detail in the following specific embodiments, and the content is sufficient for any person skilled in the art to understand the technical content of the present application and implement it accordingly. Based on the specification, claims and drawings disclosed in this specification, those skilled in the art can easily understand the related purposes and advantages of the present application.

[0059] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0060] In the description of this embodiment, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "bottom", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product is usually placed during use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0061] To make the objectives, technical solutions and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the drawings.

[0062] Please refer to Figure 1 , the present application provides an aerosol-generating article 2, which includes a filter segment 21, a substrate segment 22 and a cigarette paper 27. The filter segment 21 and the substrate segment 22 are disposed in the cigarette paper 27.

[0063] The filter segment 21 is located at the proximal end of the aerosol-generating article 2, and the substrate segment 22 is located at the distal end of the aerosol-generating article 2.

[0064] The substrate segment 22 is provided with a first flue gas outlet 25 at the distal end. The substrate segment 22 is placed in the heating chamber 14 of the aerosol-generating device 1 for heating to generate aerosol and flow out from the first flue gas outlet 25.

[0065] A sealing partition 23 is disposed between the filter segment 21 and the substrate segment 22. The sealing partition 23 is used to prevent the aerosol from directly flowing from the substrate segment 22 to the filter segment 21.

[0066] The filter segment 21 is provided with a breathable segment 26 near the sealing partition 23.

[0067] It can be understood that the breathable segment 26 can serve as the first flue gas inlet, and the sealing partition 23 can cooperate with the first flue gas outlet 25 to allow the aerosol to flow out of the substrate segment 22 from the first flue gas outlet 25, and then the aerosol flows into the filter segment 21 from the first flue gas inlet to extend the flow distance of the aerosol.

[0068] Please refer to Figure 2 , the sealing partition 23 can be made of a flexible material that can withstand high temperatures (up to 300 °C) and is airtight. Exemplarily, the flexible material can be aluminum foil. When the sealing partition 23 is made of a flexible material, its side is closely attached to the cigarette paper 27, is arranged around the proximal end of the matrix section 22, and seals the proximal end of the matrix section 22.

[0069] It can be understood that materials such as aluminum foil are relatively thin and have the characteristic of being easily bent. When manufacturing the matrix section 22, the packaging of the matrix section 22 can be made such that the distal end of the matrix section 22 is exposed, forming the first flue gas outlet 25.

[0070] The sealing partition 23 can also be made of a rigid material. Exemplarily, the rigid material can be ceramic, polyether ether ketone, or fiberglass. When the sealing partition 23 is made of a rigid material, it can be in the form of a sheet with a certain thickness, so that the sealing partition 23 is closely attached to the cigarette paper 27. Forms such as bonding can be used, and adhesives can be selected from polyvinyl butyral, polyacrylate polymers, water-based adhesives, etc.

[0071] In order to simultaneously seal the gas path and effectively reduce the volume of the aerosol generating article 2, the thickness of the sealing partition 23 is preferably set to be less than or equal to 5 millimeters.

[0072] The ventilation section 26 is arranged above the sealing partition 23, and an air inlet is arranged on its surface. The air inlet is arranged around the ventilation section 26.

[0073] The ventilation section 26 can be a separate ventilation element, and the ventilation element is connected to the filter section 21 and the matrix section 22 by means of separate splicing.

[0074] The ventilation section 26 can also be integrated with the cigarette paper 27, that is, the cigarette paper 27 has a ventilation section 26. Under the condition of meeting the support of the aerosol generating article 2, holes can be punched at this position section on the cigarette paper 27.

[0075] Please also refer to Figures 3 to 5 , the air inlet can include a plurality of ventilation holes 24. The ventilation holes 24 can be rectangular holes, hexagonal holes, circular holes, or oval holes. The distribution of the ventilation holes 24 can be equally spaced or irregularly distributed.

[0076] Exemplarily, when the ventilation hole 24 is a circular hole, the cross-section of the circular hole can be a diameter of 0.5 mm to 2 mm.

[0077] The first flue gas inlet can be a ventilation hole 24. The first flue gas inlet of the filter section 21 in the aerosol generating article 2 is located above the sealing partition 23.

[0078] After the aerosol-generating article 2 is inserted into the insertion opening 18 of the aerosol-generating device 1, the ventilation holes 24 are located at the second smoke inlet 141 of the aerosol-generating device 1, and the ventilation holes 24 communicate with the second smoke inlet 141.

[0079] The ventilation holes 24 of the first smoke inlet are penetrating pores, and the cross-section of the pores can be set to any shape of an inscribed circle with a diameter of 0.5 mm to 1.5 mm, and can be evenly distributed around the aerosol-generating article 2 itself with multiple rows of holes punched.

[0080] It can be understood that the present application introduces an innovative sealing partition 23 design between the substrate section 22 and the filter section 21 of the aerosol-generating article 2. This design ensures that the high-temperature aerosol does not directly flow from the substrate section 22 to the filter section 21 inside the aerosol-generating article 2. Instead, it cleverly utilizes the ventilation holes 24 carefully configured on the filter section 21 as an optimized channel for aerosol flow.

[0081] Specifically, the aerosol is first released into the space outside the aerosol-generating article 2 in the substrate section 22, and then passes through a carefully planned gas path and is guided back into the article 2 through the ventilation holes 24 of the filter section 21. This innovative process not only significantly extends the flow path of the aerosol, but also effectively reduces the temperature of the aerosol, thereby enhancing the user's smoking experience.

[0082] It can be understood that the unique aerosol flow channel 153 design of the aerosol-generating article 2 provided by the present application can prevent the aerosol from being directly sucked, but instead be dispersed to the outside of the article 2 through the first smoke outlet 25 and then re-absorbed back into the article 2 through the first smoke inlet. With minimal changes to the original heated cigarette structure and by changing the aerosol flow path, functions such as temperature reduction, aroma enhancement, and multi-flavor filtration can be achieved during use.

[0083] The aerosol-generating article 2 is also particularly suitable for liquid-filtering smoking devices.

[0084] A liquid-filtering smoking device refers to a smoking device that filters tobacco smoke through a liquid, such as a water pipe smoking device, an oil-filtering smoking device, or a mixed liquid-filtering smoking device, etc.

[0085] During the flow of the aerosol, harmful substances in the aerosol can be filtered through the liquid, and the suction taste can be further enhanced through the liquid.

[0086] Please refer to Figure 2 and Figure 3 , the present application provides an aerosol-generating device 1, which includes: a heating chamber 14, a housing 15, a heating system, an air flow channel 152, an aerosol flow channel 153, and a medium chamber 17.

[0087] Among them, the heating chamber 14 is at the proximal position inside the housing 15. A second flue gas inlet 141 is provided at the bottom of the heating chamber 14, and the aerosol flowing out from the first flue gas outlet 25 flows into the second flue gas inlet 141.

[0088] An insertion port 18 through which the aerosol generating article 2 can be inserted and enter the heating chamber 14 is provided at the top of the housing 15. A second flue gas outlet 142 is provided between the insertion port 18 and the heating chamber 14. The aerosol flow channel 153 connects the second flue gas inlet 141 and the second flue gas outlet 142, and the second flue gas outlet 142 is communicated with the first flue gas inlet.

[0089] An air inlet 151 is provided on the surface of the housing 15, and the air flow channel 152 communicates the air inlet 151 and the aerosol flow channel 153.

[0090] The heating system may include a heating element 13, and the heating element 13 can be in thermal contact with the aerosol generating article 2 inserted into the heating chamber 14.

[0091] Exemplarily, the heating element 13 can be an external heating element, and the external heating element is used for externally heating the matrix section 22 of the aerosol generating article 2.

[0092] A sealing assembly 12 is provided between the insertion port 18 and the heating chamber 14. The sealing assembly 12 can be used to seal and connect the second flue gas outlet 142 and the aerosol flow channel 153 to prevent the aerosol from accidentally flowing out of the aerosol generating device 1 during the circulation process.

[0093] Exemplarily, the structure of the sealing assembly 12 can be annular, and the cross-sectional shape can be circular, square or trapezoidal, etc., mainly used for sealing the gas circulation channel.

[0094] Preferably, the sealing assembly 12 can be made of an elastic material resistant to temperatures above 50°C and corrosion and oil resistance, such as: fluororubber (FKM), polytetrafluoroethylene (PTFE), hydrogenated nitrile rubber (HNBR), etc.

[0095] The medium chamber 17 is arranged at the distal position inside the housing 15, that is, the medium chamber 17 is located below the second flue gas inlet 141 of the heating chamber 14.

[0096] The medium chamber 17 is communicated with the aerosol flow channel 153. The medium chamber 17 is used for placing the flavor medium 16. The flavor medium 16 is heated to form a flavor gas, and the flavor gas enters the aerosol flow channel 153 to be mixed with the aerosol.

[0097] The flavor medium 16 can be a liquid medium, which can be water, juice, spices or other flavoring extracts. These liquid media can not only effectively filter and cool the aerosol during the heating process, but also add a unique and charming flavor to it, making the smoking experience richer and more enjoyable.

[0098] Specifically, a third smoke inlet 171 and a third smoke outlet 172 are provided on the top surface of the medium chamber 17 . The third smoke inlet 171 is provided below the second smoke outlet 142 . The third smoke outlet 172 is adjacent to and spaced from the third smoke inlet 171 .

[0099] The third smoke inlet 171 and the third smoke outlet 172 are in communication with the aerosol flow channel 153 so as to filter and cool the aerosol flowing through the aerosol under the action of the liquid medium.

[0100] Exemplarily, the third smoke inlet 171 may be disposed at the middle of the top surface of the medium chamber 17, which corresponds to the lower portion of the second smoke outlet 142. The third smoke outlet 172 may be single or multiple and disposed around the third smoke inlet 171.

[0101] The third smoke inlet 171 and the third smoke outlet 172 are arranged at a non-uniform height on the same horizontal plane.

[0102] For example, the third smoke inlet 171 is disposed at a relatively high position in the medium chamber 17 , close to the heating chamber 14 , while the third smoke outlet 172 is disposed at a relatively low position in the medium chamber 17 , away from the heating chamber 14 .

[0103] The third smoke inlet 171 and the third smoke outlet 172 are provided with a breathable membrane 19 .

[0104] This layer of breathable film 19 blocks the direct contact between the flavor medium 16 and the heating element 13 , thereby ensuring the purity and efficiency of the heating process and preventing the flavor medium 16 from damaging the heating element 13 .

[0105] In the implementation of the present application, the flavor medium 16 is a liquid medium to ensure the richness and purity of the flavor. The breathable membrane 19 can be made of a special membrane material that has excellent gas permeability but can effectively block liquid penetration, such as expanded polytetrafluoroethylene (ePTFE), polytetrafluoroethylene (PTFE), polyethylene (PE) or high-density non-woven fabrics, etc. The cross-section of the breathable membrane 19 can be matched with other materials to achieve the effect of sealing the liquid medium.

[0106] Under the heating effect of the heating chamber 14, the aerosol can flow out from the second flue gas outlet 142 and flow into the medium chamber 17 through the third flue gas inlet 171. At this time, the liquid medium in the medium chamber 17 can filter and cool the aerosol. When the user sucks the article 2, the filtered and cooled aerosol flows out of the medium chamber 17 through the third flue gas inlet / outlet and is remixed into the aerosol circulation again.

[0107] The matrix section 22 of the aerosol generating article 2 is arranged in the heating chamber 14, and there is a certain interval between the matrix section 22 and the bottom of the heating chamber 14. The interval can be set between 2 mm and 20 mm so that the air in the air flow channel 152 flows through the matrix section 22, facilitating the heating member 13 to heat the aerosol generating article 2 to generate aerosol.

[0108] Exemplarily, a mesh can be provided at the bottom of the heating chamber 14, and the matrix section 22 of the aerosol generating article 2 is placed on the mesh.

[0109] The heating chamber 14 is located at the proximal end inside the housing 15, the medium chamber 17 is located at the distal end inside the housing 15, and an air inlet 151 is provided on the outer surface of the housing 15 between the heating chamber 14 and the medium chamber 17.

[0110] An insertion port 18 is provided at the top of the housing 15, and a second flue gas inlet 141 is provided between the insertion port 18 and the heating chamber 14. The air inlet 151, the second flue gas inlet 141 are communicated with the bottom of the heating chamber 14 to form an aerosol flow channel 153.

[0111] The air inlet 151 is used to connect the outside air with the channel inlet inside the aerosol generating device 1.

[0112] The cross-section of the air inlet 151 can be any shape such as an inscribed circle, square, etc. with a diameter of 0.5 mm to 1 mm or 1 mm to 2 mm. The air inlet 151 can be arranged around the inside of the aerosol generating device 1, and the number of channels of the air inlet 151 is greater than 1.

[0113] Based on the same inventive concept, the present application also provides an aerosol generating system including the aerosol generating device 1 and the aerosol generating article 2 described above.

[0114] Specifically, after the aerosol generating article 2 is inserted into the heating chamber 14 of the aerosol generating device 1, the heating system of the aerosol generating device 1 heats the matrix section 22 of the aerosol generating article 2 to generate aerosol.

[0115] When the user sucks, the external air enters from the air inlet 151 on the housing 15, and cooperates with the heated aerosol, passes through the breathable membrane 19 provided inside the aerosol generating device 1, and enters the medium chamber 17.

[0116] The aerosol and the heated air continue to flow into the medium chamber 17. The aerosol and the heated air flow through the liquid medium, and then continue to flow upward along the breathable membrane 19 on the side of the medium chamber 17, and finally enter the filter section 21 of the aerosol generating article 2 through the air holes 24 of the aerosol generating article 2 for the consumer to inhale.

[0117] It should be noted that for the specific structures of the aerosol generating device 1 and the aerosol generating article 2, reference can be made to the above, which will not be elaborated here.

[0118] It can be understood that this application combines the enjoyment experience of hookah, the temperature control accuracy of heating appliances, and the convenience of heated tobacco products, and innovatively proposes a portable device and an aerosol generating article that do not require changing the original basic structure and components of the cigarette.

[0119] This solution aims to achieve precise temperature control, so as to significantly improve the taste and flavor level of heated tobacco products while maintaining the pure flavor of traditional tobacco. More advanced is that this design takes into account the portability and comfort of use, allowing users to experience the convenience and comfort brought by modern technology while enjoying the flavor of traditional tobacco.

[0120] It should be understood that in the aerosol generating device provided by the present invention, the first processor can be used to control the temperature of the heating system. The first processor can be a central processing unit (CPU), and this processor can also be other general-purpose processors, digital signal processors (DSPs), application specific integrated circuits (ASICs), field programmable gate arrays (FPGAs) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor can be a microprocessor or this processor can also be any conventional processor, etc.

[0121] It should also be understood that the memory in the sol generation device in the embodiments of the present invention can store the heating curve used by the sol generation device to control the heating temperature.

Among them, the non-volatile memory can be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), or a flash memory. The volatile memory can be a random access memory (RAM), which is used as an external cache. By way of example but not limitation, many forms of random access memory (RAM) are available, such as static random access memory (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate synchronous dynamic random access memory (DDR SDRAM), enhanced synchronous dynamic random access memory (ESDRAM), synchlink dynamic random access memory (SLDRAM), and direct rambus random access memory (DR RAM).

For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. Among them, A and B can be singular or plural. In addition, the character " / " in this article generally represents an "or" relationship between the associated objects before and after, but it may also represent an "and / or" relationship, which can be specifically understood by referring to the context before and after.
