Description

Technical Field

[0001] This application belongs to the field of new tobacco, and specifically relates to an aerosol generating article and an aerosol generating device. Background Art

[0002] Traditional hookahs usually use charcoal as a heat source to heat a material composed of glycerin, fructose, and tobacco, thereby generating vapor for people to inhale. Its uniqueness lies in that through the filtering and cooling effects of the liquid, the inhaled smoke becomes smoother, softer, and cooler, greatly reducing irritation. At the same time, the liquid components in hookahs are diverse and can be clear water, fruit juice, herbal tea, milk, or even liquor. When the smoke passes through these liquids, it will carry the unique aroma of the liquid, making the smoking experience more rich and varied. However, traditional hookahs also have some deficiencies. For example, the temperature control is not precise enough, the equipment is relatively bulky, with numerous components, making it inconvenient to move, carry, and store. Moreover, the cleaning is rather cumbersome, and the preparation work before use is also complex, requiring certain experience and skills.

[0003] A heating appliance is a new type of tobacco product that uses non-combustion methods such as resistance heating, electromagnetic induction, or infrared radiation. Its working principle is that through precise temperature control technology, the heated cigarette is heated to a specific temperature, enabling nicotine and flavor substances in the tobacco to generate inhalable aerosol under pyrolysis.

[0004] An electronic hookah is a clever combination of a cartridge-based e-cigarette and a traditional hookah. It successfully solves the problems of traditional hookah equipment being bulky and not easy to carry. However, unfortunately, it cannot directly use traditional cigarettes or heated cigarettes as consumables, and what it actually consumes is flavoring substances such as e-liquid.

[0005] The above several types of smoking devices each have their own characteristics, advantages, and limitations. In the current market, consumers are urgently looking forward to a new type of heating smoking device to meet their increasingly diverse and personalized selection needs. Summary of the Invention

[0006] In view of this, the purpose of this application is to provide an aerosol generating article and an aerosol generating article device to solve the above problems.

[0007] To solve the above technical problems, this application adopts the following technical solutions:

[0008] In a first aspect, the present application provides an aerosol-generating article, which includes a filter segment and a substrate segment. The filter segment is located at the proximal end of the aerosol-generating article, and the substrate segment is located at the distal end of the aerosol-generating article. The substrate segment is provided with a first flue gas outlet at the distal end. The substrate segment is placed in a heating chamber of an aerosol-generating device to be heated to generate aerosol and flow out from the first flue gas outlet. A sealing partition is provided between the filter segment and the substrate segment, and the sealing partition is used to prevent the aerosol from directly flowing from the substrate segment to the filter segment; the filter segment is provided with a first flue gas inlet near the sealing partition.

[0009] Further, the aerosol-generating article is used for a liquid-filtering smoking device.

[0010] In a second aspect, the present application provides an aerosol-generating device for heating the aerosol-generating article of the first aspect. The device includes a heating chamber, a housing, a heating element, an air flow channel, and an aerosol flow channel; the heating chamber is inside the housing, and a second flue gas inlet is opened at the bottom of the heating chamber. The aerosol flowing out from the first flue gas outlet flows into the second flue gas inlet; an insertion port through which the aerosol-generating article can be inserted and enter the heating chamber is opened at the top of the housing. A second flue gas outlet is provided between the insertion port and the heating chamber. The aerosol flow channel connects the second flue gas inlet and the second flue gas outlet, and the second flue gas outlet is communicated with the first flue gas inlet; an air inlet is provided on the surface of the housing, and the air flow channel communicates the air inlet and the aerosol flow channel; the heating element can be in thermal contact with the aerosol-generating article inserted into the heating chamber.

[0011] Further, the aerosol-generating device further includes a sealing assembly provided between the insertion port and the heating chamber for sealingly connecting the second flue gas outlet and the aerosol flow channel.

[0012] Further, the aerosol-generating device further includes a medium chamber provided below the second flue gas inlet, and the medium chamber is communicated with the aerosol flow channel. The medium chamber is used for placing a flavor medium, and the flavor medium is heated to form a flavor gas, and the flavor gas enters the aerosol flow channel to be mixed with the aerosol.

[0013] Further, a third flue gas inlet and a third flue gas outlet are provided at the top of the medium chamber. The third flue gas inlet is provided below the second flue gas inlet, and the third flue gas outlet is arranged adjacent to and spaced from the third flue gas inlet; the third flue gas inlet and the third flue gas outlet are communicated with the aerosol flow channel.

[0014] Further, a breathable membrane is provided at the third flue gas inlet and the third flue gas outlet, and the material of the breathable membrane is any one of expanded polytetrafluoroethylene (ePTFE), polytetrafluoroethylene (PTFE), polyethylene (PE), and high-density non-woven fabric.

[0015] Further, the substrate section of the aerosol - generating article is disposed in the heating chamber, and there is a gap between the substrate section and the bottom of the heating chamber.

[0016] Further, the air inlet is disposed between the heating chamber and the medium chamber.

[0017] Further, the flavor medium is a liquid medium.

[0018] Among them, 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 can include both solid and liquid components simultaneously. Preferably, the aerosol - forming substrate includes nicotine. In some preferred embodiments, the aerosol - forming substrate includes tobacco.

[0019] 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 active ingredients 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.

[0020] An aerosol - generating device is a device used to interact 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.

[0021] 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.

[0022] 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.

[0023] 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 receive the aerosol - generating articles in a corresponding number of heating chambers.

[0024] 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 that combines both internal and external elements; however, it is not limited to this, as long as it can be used to heat the aerosol-generating article to produce an aerosol for inhalation.

[0025] 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:

[0026] Firstly, by ingeniously incorporating a flavor medium into the aerosol-generating device in this application and designing the heating element to heat both the aerosol-generating article and this flavor medium simultaneously, an aerosol with a unique flavor is generated, greatly enhancing the consumer's inhalation experience.

[0027] Secondly, the smoke inlet and outlet on the article, the smoke inlet and outlet on the device are in communication with the aerosol flow channel, and the aerosol flow channel is in communication with the heating chamber. Under the guidance of the carefully arranged aerosol flow channel inside the aerosol-generating device, the high-temperature aerosol flows in the aerosol flow channel, passes through the smoke inlet and outlet of the medium chamber, and fully acts on the flavor medium in the medium chamber, ensuring that the flavor medium is heated evenly and sufficiently, further enhancing the taste enjoyment during inhalation. At the same time, it also extends the flow distance of the aerosol in the aerosol flow channel to reduce the high temperature of the aerosol and solve the problem of the user's mouth feeling scalded during inhalation.

[0055] The following details the detailed features and advantages of the present application in the detailed implementation manners. The content is sufficient for any person skilled in the art to understand the technical content of the present application and implement it accordingly. And according to the description, claims and drawings disclosed in this specification, those skilled in the art can easily understand the relevant purposes and advantages of the present application.

[0056] 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.

[0057] 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.

[0058] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe in detail the embodiments of the present application with reference to the drawings.

[0059] Please refer to Figure 1 , the present application provides an aerosol-generating article 2, which includes a filter segment 21 and a substrate segment 22.

[0060] 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.

[0061] 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 and heated to generate aerosol, which flows out from the first flue gas outlet 25.

[0062] A sealing partition 23 is provided 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.

[0063] The filter segment 21 is provided with a first flue gas inlet 24 at a position close to the sealing partition 23.

[0064] It can be understood that 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 24 to extend the flow distance of the aerosol.

[0065] The material of the sealing partition 23 can be selected as a material that can withstand high temperatures (up to 300 °C) and is airtight to ensure a tight and reliable airtight fit with the paper inner wall of the aerosol-generating article 2.

[0066] Preferably, the material of the sealing partition 23 can be aluminum foil, ceramic, fiberglass, etc.

[0067] The first flue gas inlet 24 of the filter segment 21 in the aerosol-generating article 2 is located above the sealing partition 23.

[0068] The first aerosol inlet 24 can be a ventilation hole. After the aerosol generating article 2 is inserted into the insertion port 18 of the aerosol generating device 1, the ventilation hole is located at the second aerosol inlet 141 of the aerosol generating device 1, and the ventilation hole communicates with the second aerosol inlet 141.

[0069] The ventilation hole of the first aerosol inlet 24 is a penetrating air hole, and the cross-section of the air hole 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.

[0070] It can be understood that the present application introduces an innovative sealed 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 into the filter section 21 inside the article 2. Instead, it cleverly utilizes the ventilation holes carefully configured on the filter section 21 as an optimized channel for aerosol flow.

[0071] Specifically, the aerosol is first released into the space outside the article 2 in the substrate section 22, and then through a carefully planned gas path, it is guided back into the article 2 through the ventilation holes 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.

[0072] The aerosol generating article 2 is also particularly suitable for liquid filtration type smoking devices.

[0073] A liquid filtration type smoking device refers to a smoking device that filters tobacco smoke through a liquid, such as a water pipe smoking device, an oil filtration smoking device, or a mixed liquid filtration smoking device, etc.

[0074] It can be understood that the unique aerosol flow channel design of the aerosol generating article 2 provided by the present application enables the aerosol not to be directly sucked, but to be dispersed to the outside of the article 2 through the first aerosol outlet 25, and then re-absorbed back into the article 2 through the first aerosol inlet 24. During the flow of the aerosol, harmful substances in the aerosol can be filtered by the liquid, and the suction taste can be further enhanced by the liquid.

[0075] 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.

[0076] Among them, the heating chamber 14 is at the proximal position inside the housing 15, and a second aerosol inlet 141 is opened at the bottom of the heating chamber 14, and the aerosol flowing out from the first aerosol outlet 25 flows into the second aerosol inlet 141.

[0077] An insertion port 18 is provided at the top of the shell 15 for inserting the aerosol generating product 2 into the heating chamber 14, a second smoke outlet 142 is provided between the insertion port 18 and the heating chamber 14, an aerosol flow channel 153 connects the second smoke inlet 141 and the second smoke outlet 142, and the second smoke outlet 142 is communicated with the first smoke inlet 24.

[0078] An air inlet 151 is disposed on the surface of the housing 15 , and an air channel 152 connects the air inlet 151 and the aerosol channel 153 .

[0079] The heating system may comprise a heating element 13 which may be in thermal contact with the aerosol-generating article 2 inserted into the heating chamber 14 .

[0080] Exemplarily, the heating element 13 may be an external heating element for heating the outer surface of the substrate segment 22 of the aerosol-generating article 2 .

[0081] A sealing component 12 is provided between the insertion port 18 and the heating chamber 14 , and the sealing component 12 can be used to seal and connect the second smoke outlet 142 and the aerosol flow channel 153 to prevent the aerosol from accidentally flowing out of the aerosol generating device 1 during circulation.

[0082] Exemplarily, the structure of the sealing component 12 may be annular, and the cross-sectional shape may be circular, square, trapezoidal, etc., and it is mainly used to seal the flow channel of the gas.

[0083] Preferably, the sealing component 12 can be made of an elastic material that is resistant to temperatures above 50° C. and is corrosion-resistant and oil-resistant, such as fluororubber (FKM), polytetrafluoroethylene (PTFE), hydrogenated nitrile rubber (HNBR), and the like.

[0084] The medium chamber 17 is disposed at a distal position in the housing 15 , that is, the medium chamber 17 is located below the second smoke inlet 141 of the heating chamber 14 .

[0085] The medium chamber 17 is communicated with the aerosol flow channel 153 . The medium chamber 17 is used to place the flavor medium 16 . The flavor medium 16 is heated to form a flavor gas. The flavor gas enters the aerosol flow channel 153 and mixes with the aerosol.

[0086] 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.

[0087] Specifically, a third flue gas inlet 171 and a third flue gas outlet 172 are provided on the top surface of the medium chamber 17. The third flue gas inlet 171 is provided below the second flue gas outlet 142, and the third flue gas outlet 172 is arranged adjacent to and spaced from the third flue gas inlet 171.

[0088] The third flue gas inlet 171 and the third flue gas outlet 172 are communicated with the aerosol flow channel 153 to filter and cool the flowing aerosol under the action of the liquid medium.

[0089] Exemplarily, the third flue gas inlet 171 can be provided at the middle position of the top surface of the medium chamber 17, and this middle position exactly corresponds to the position below the second flue gas outlet 142. The third flue gas outlet 172 can be single or multiple, and is arranged around the third flue gas inlet 171.

[0090] The third flue gas inlet 171 and the third flue gas outlet 172 are arranged at non-uniform heights on the same horizontal plane.

[0091] For example: The third flue gas inlet 171 is arranged at a relatively high position in the medium chamber 17, adjacent to the heating chamber 14, while the third flue gas outlet 172 is located at a relatively low position in the medium chamber 17, far from the heating chamber 14.

[0092] The third flue gas inlet 171 and the third flue gas outlet 172 are provided with a breathable membrane 19.

[0093] This breathable membrane 19 blocks the direct contact between the flavor medium 16 and the heating element 13, ensures purity and efficiency during the heating process, and prevents damage to the heating element 13 by the flavor medium 16.

[0094] In an implementable manner of the present application, the flavor medium 16 is a liquid medium to ensure rich and pure flavor. And the breathable membrane 19 can be made of a special membrane material, which has excellent gas permeability but can effectively block the penetration of liquid, such as: expanded polytetrafluoroethylene (ePTFE), polytetrafluoroethylene (PTFE), polyethylene (PE) or high-density non-woven fabric, etc. The cross-section of the breathable membrane 19 can be combined with other materials to achieve the effect of enclosing the liquid medium.

[0095] Under the heating action 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 and outlet and is remixed into the aerosol flow.

[0096] The matrix section 22 of the aerosol-generating article 2 is disposed in the heating chamber 14, and there is a certain interval between the matrix section 22 and the bottom of the heating chamber 14, and the interval can be set between 2 mm and 20 mm, so that the air in the air flow path 152 flows through the matrix section 22, facilitating the heating member 13 to heat the aerosol-generating article 2 to generate aerosol.

[0097] 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.

[0098] The heating chamber 14 is located at the proximal end within the housing 15, the medium chamber 17 is located at the distal end within 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.

[0099] 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 in communication with the bottom of the heating chamber 14 to form an aerosol flow path 153.

[0100] The air inlet 151 is used to connect the outside air with the channel inlet inside the aerosol-generating device 1.

[0101] The cross-section of the air inlet 151 can be any shape such as an inscribed circle, a square, etc. with a diameter of 0.5 mm to 1 mm or 1 mm to 2 mm. The air inlet 151 can be distributed around the inside of the aerosol-generating device 1, and the number of channels of the air inlet 151 is greater than 1.

[0102] 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.

[0103] 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.

[0104] When the user performs suction, the external air enters through 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.

[0105] 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 respectively 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 ventilation holes of the aerosol-generating article 2 for the consumer to inhale.

[0106] It should be noted that for the specific structures of the aerosol generating device 1 and the aerosol generating article 2, reference may be made to the above text and will not be elaborated herein.

[0107] It can be understood that this application combines the enjoyment experience of hookah, the temperature control precision of heating appliances, and the convenience of heated cigarettes, 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 stick.

[0108] This solution aims to achieve precise temperature control, thereby significantly enhancing the taste and flavor levels of heated cigarettes while maintaining the pure flavor of traditional tobacco. More advancedly, 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.
