Description

Technical Field

[0001] The present application relates to the field of smoke generation technology, and in particular to a cooling component and an aerosol generating product. Background Art

[0002] Aerosol generating products generally generate aerosols by heating without burning. Specifically, an aerosol generating matrix is ​​provided in the aerosol generating product. The aerosol generating product is loaded into an aerosol generating device and heated by a heating component in the aerosol generating device so that the aerosol generating matrix segment is heated just to a degree sufficient to emit a fragrance, but the aerosol generating matrix segment does not burn.

[0003] Since the temperature of the aerosol generated by the aerosol generating matrix during the heating process is relatively high, in order to lower the temperature of the aerosol, the aerosol generating product generally has a cooling section at one end of the aerosol generating matrix. The aerosol flowing out of the aerosol generating matrix is ​​cooled in the cooling section before entering the user's mouth.

[0004] In the related art, the cooling section is mainly achieved by the following two methods: 1. Adding phase change materials to the cooling section, absorbing the heat of the aerosol through the phase change of the phase change materials, thereby achieving the purpose of cooling the aerosol; 2. Setting a bending channel for the aerosol to pass through in the cooling section, and using the bending channel to extend the diffusion path of the aerosol to achieve the purpose of cooling the aerosol. Although these cooling methods can reduce the temperature of the aerosol, they also have certain defects. For example, the addition of phase change materials makes the manufacturing process of aerosol-generating products more complicated and increases the cost of aerosol-generating products. In addition, the presence of phase change materials will enhance the hygroscopic capacity of aerosol-generating products, thereby reducing the stability of aerosol-generating products. Setting a bending channel in the cooling section is not only difficult to implement in industry, but the excessively long path will also play a role in adsorbing the aerosol, which ultimately leads to too low atomization volume of the aerosol-generating product, affecting the user experience.

[0046] In the description of the embodiments of the present application, it should be noted that the orientation or position relationship indicated by the term "first direction" or the like is based on the attached Figure 1 The orientation or positional relationship shown, these orientation terms are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0047] The present application embodiment provides an aerosol generating product, please refer to Figure 1 and Figure 2 The aerosol generating product includes an aerosol generating substrate segment 20 and a cooling component 10.

[0048] The aerosol generating product is used in conjunction with an aerosol generating device. Specifically, the aerosol generating device heats and atomizes the aerosol generating substrate segment 20 to generate an aerosol for users to inhale or for use in medicine, beauty, etc.

[0049] The specific structure of the aerosol generating matrix segment 20 is not limited here. For example, in one embodiment, the aerosol generating matrix segment 20 can be made of the atomizing medium itself, for example, made of the smoke flavoring medium. In other embodiments, the aerosol generating matrix segment 20 can also include a matrix and an atomizing medium disposed on the matrix. The matrix can be, for example, high temperature resistant carbon fiber. In this way, by providing the matrix, the strength of the aerosol generating matrix segment 20 can be improved, and it can also withstand a certain degree of high temperature without generating odor.

[0050] The specific components of the aerosol generating matrix segment 20 are not limited herein. For example, in one embodiment, the aerosol generating matrix segment 20 may include plant components, auxiliary components, smoke generating agent components, adhesive components, etc.

[0051] In one embodiment, the plant component is one or more combinations of powders formed by crushing tobacco raw materials, tobacco leaf fragments, tobacco stems, tobacco dust, and aromatic plants. The plant component is the core source of the flavor of the product. Endogenous substances in the plant component, such as nicotine, enter the human blood through atomization, promote the pituitary gland to produce dopamine, and thus obtain physiological satisfaction.

[0052] In one embodiment, the auxiliary agent component can be one or more combinations of inorganic fillers, lubricants, and emulsifiers. Among them, the inorganic filler includes one or more combinations of heavy calcium carbonate, light calcium carbonate, zeolite, attapulgite, talc, and diatomaceous earth. The inorganic filler can provide a skeleton support for the plant component, and the inorganic filler also has micropores, which can increase the porosity of the wall material after the plant component is formed, thereby increasing the aerosol release rate.

[0053] The lubricant includes one or more combinations of candelilla wax, carnauba wax, shellac, sunflower wax, rice bran, beeswax, stearic acid, and palmitic acid. The lubricant can increase the fluidity of the particles, reduce the friction between the particles, make the overall density of the particle distribution more uniform, and also reduce the pressure required for mold molding and reduce the wear of the mold.

[0054] Emulsifiers include one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. Emulsifiers can slow down the loss of flavor substances during storage to a certain extent, increase the stability of flavor substances, and improve the sensory quality of products. Emulsifiers (also known as surfactants) can reduce the interfacial tension of water-soluble and water-insoluble components in the mixed system, and form a relatively strong film on the surface of the droplets or form a double electric layer on the surface of the droplets due to the charge given by the emulsifier, preventing the droplets from aggregating with each other and maintaining a uniform emulsion. Emulsifying and homogenizing two immiscible components can improve the consistency of product quality.

[0055] The function of the smoke-generating agent component is to generate a large amount of steam when heated, thereby increasing the amount of smoke of the smoking product. In one embodiment, the smoke-generating agent may include, for example: a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, triethylene glycol, 1,3-butylene glycol and glycerol); an ester of a polyhydric alcohol (such as monoacetin, diacetin or triacetin); a monocarboxylic acid; a polycarboxylic acid (such as lauric acid, myristic acid) or an aliphatic ester of a polycarboxylic acid (such as dimethyl dodecanedioate, dimethyl tetradecanedioate, erythritol, 1,3-butylene glycol, tetraethylene glycol, triethyl citrate, propylene carbonate, ethyl laurate, Triactin, meso-erythritol, diacetin mixture, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, glyceryl tributyrate, lauryl acetate) or one or more combinations thereof.

[0056] In one embodiment, the adhesive component is a natural plant extract, a non-ionized modified viscous polysaccharide, including one or more combinations of tamarind polysaccharide, pullulan, seaweed polysaccharide, locust bean gum, guar gum, and xyloglucan. The adhesive is in close contact with the interface of the product component material by wetting, generating an intermolecular attraction, thereby playing the role of bonding the powder, liquid, etc. of the component material. At the same time, the use of natural plant extracts and non-ionic adhesives can avoid the release of harmful substances such as methanol, formaldehyde, and acrolein caused by colloid modification, thereby improving the safety of the product.

[0057] In one embodiment, the aerosol generating matrix segment 20 may further include a light absorbing material, which is a material with a high absorption rate for laser light and may be better suited for laser heating.

[0058] Exemplarily, the aerosol generating matrix section 20 can be a particle combination, and the particle combination is a reconstituted tobacco medium, for example, a reconstituted tobacco medium containing components such as smoke-generating agent and tobacco. The aerosol generating matrix section 20 is an integrated structure, for example, an integrated structure that can be formed by injection molding, compression molding or extrusion technology. Wherein extrusion molding refers to adding a raw material mixture into an extruder, and the material is pushed forward by the screw through the action between the extruder barrel and the screw, and continuously passes through the die head to make various cross-section products or semi-finished products. The aerosol matrix formed by extrusion molding is in strip shape.

[0059] Since the aerosol generating matrix segment 20 is a particle combination, it is an integrated medium when the aerosol generating matrix segment 20 is heated and sucked or stops being heated, and is not prone to disintegration and falling off. This solves the problems in the prior art of the thin sheet, filamentary or loose particle aerosol generating matrix segment 20, such as loose sheets, falling of filamentary components and particle components, and difficulty in cleaning.

[0060] The shape of the aerosol generating substrate segment 20 is also not limited. For example, the aerosol generating substrate segment 20 can be cylindrical. The cross-section of the cylindrical aerosol generating substrate segment 20 can be circular, polygonal (including but not limited to triangle, square, prism, etc.), elliptical, racetrack-shaped, irregular, etc., wherein the irregular refers to other symmetrical or asymmetrical shapes other than the shapes listed above.

[0061] The aerosol generating substrate segment 20 may be provided with an airway 20a. Figure 2 The air channel 20a runs through two opposite ends of the aerosol generating substrate segment 20 along the first direction. In some embodiments, the air channel 20a may also only run through one end of the aerosol generating substrate segment 20 along the first direction, while the other opposite end is a closed end.

[0062] Compared with the air passage 20a penetrating one end of the aerosol generating substrate segment 20 along the first direction, the air passage 20a penetrating both ends of the aerosol generating substrate segment 20 along the first direction is more conducive to reducing the inhalation resistance of the user.

[0063] The number of the air passage 20a may be one or more.

[0064] The airway 20a may be as follows Figure 2 The straight airway shown is an airway extending along a straight line, or in other words, the extending direction of the straight airway is a straight line.

[0065] The airway 20a may also be a spiral airway. A spiral airway is an airway in which at least a portion of the area along the extension direction is in a curved shape with a curvature not equal to zero. For example, along the extension direction of the spiral airway, the spiral airway may have a structure in which there are both a curved segment with a curvature not equal to zero and a straight segment with a curvature of zero, or may have only a curved segment with a curvature not equal to zero and no straight segment with a curvature of zero. In other words, from the starting point to the end point of the spiral airway along the extension direction, the spiral airway does not need to extend along a straight line.

[0066] When there are multiple air passages 20a, some of the air passages 20a may be straight air passages, and other air passages 20a may be spiral air passages.

[0067] The shape of the cross section of the airway 20a is not limited. For example, the cross section may be circular, polygonal (including but not limited to triangle, square, prism, etc.), elliptical, racetrack-shaped or irregular-shaped.

[0068] The airway 20a can extend the airflow path and increase the flow speed of the airflow in the aerosol generating matrix segment 20, thereby increasing the impact force of the airflow and allowing the aerosol to be evenly mixed, thereby improving the extraction efficiency and uniformity of the aerosol in the aerosol generating matrix segment 20 and enhancing the user's inhalation experience.

[0069] Please continue reading Figures 1 to 3 The cooling component 10 of the embodiment of the present application is arranged at one end of the aerosol generating substrate segment 20 along the first direction. The cooling component 10 comprises a rotating member 11 and a housing 12 having a cooling channel 12a, wherein the rotating member 11 is rotatably arranged in the cooling channel 12a to rotate by the action of the airflow during the inhalation process of the aerosol generating product.

[0070] The first direction may be any direction of the aerosol generating substrate segment 20, for example, see Figure 1 The first direction may be the height direction of the aerosol generating substrate segment 20. In other embodiments, the first direction may also be the length direction or the width direction of the aerosol generating substrate segment 20 (wherein the height direction, the length direction and the width direction are perpendicular to each other). The first direction may also be inclined relative to at least two of the length direction, the width direction and the height direction of the aerosol generating substrate segment 20.

[0071] For example, see Figure 1 For a columnar aerosol-generating substrate segment 20 , the first direction may be the elongation direction (ie, height direction) of the aerosol-generating substrate segment 20 .

[0072] The shell 12 mainly plays a supporting role. For example, the shell 12 can be made of paper or polymer materials, etc. The shell 12 can also be a hard tube or a soft tube. The inside of the shell 12 has a cavity forming a cooling channel 12a.

[0073] The cooling component 10 is mainly used to cool the aerosol. Specifically, the cooling channel 12a has an air inlet end and an air outlet end, and the air inlet end is connected to the aerosol generating matrix segment 20. When the aerosol generating matrix segment 20 is heated, the aerosol generating matrix segment 20 releases the aerosol. During the user's inhalation process, the external airflow carries the aerosol into the cooling channel 12a from the air inlet end and then flows out from the air outlet end. It should be noted that, for the aerosol generating matrix segment 20 provided with the air channel 20a, since at least part of the micropores or gaps in the wall material of the aerosol generating matrix segment 20 are connected to the air channel 20a, the aerosol released by the aerosol generating matrix segment 20 when heated can enter the air channel 20a through the micropores or gaps connected to the air channel 20a, and then enter the cooling channel 12a from the air channel 20a, while for the aerosol generating matrix segment 20 not provided with the air channel 20a, the aerosol released by the aerosol generating matrix segment 20 can directly enter the cooling channel 12a. When the airflow passes through the cooling channel 12a, it can exert a driving force on the rotating member 11, thereby realizing the rotation of the rotating member 11.

[0074] The rotating member 11 can be cast from metals such as iron, cobalt, nickel and their corresponding alloys, or can be made from one material such as PEEK (poly (ether-ether-ketone), ABS (Acrylonitrile Butadiene Styrene plastic, acrylonitrile-butadiene-styrene copolymer), PA (polyamide resin), PLA (Polylactic acid, polylactic acid, also known as polylactide), PET (PET polyethylene terephthalate, polyester resin) or a mixture of multiple materials, and prepared by extrusion, film pressing, hot pressing or injection molding.

[0075] The number of the rotating members 11 may be one or more than one. However, when the number of the rotating members 11 is too large, the interception rate of the aerosol is too large, which will reduce the utilization rate of the aerosol. Therefore, preferably, the number of the rotating members 11 may be 1 to 4 (including the endpoint values), for example, the number of the rotating members 11 may be 1, 2, 3, or 4. More preferably, the number of the rotating members 11 may be 1 to 2 (including the endpoint values).

[0076] The structure of the rotating member 11 is not limited as long as it can rotate. When the number of the rotating members 11 is greater than one, all the rotating members 11 can adopt the same structure or at least two different structures.

[0077] See also Figure 2 and Figure 5 The rotation axis Z of the rotating member 11 may be parallel to the extension direction of the cooling channel 12a, or may intersect with the extension direction of the cooling channel 12a, as long as the rotating member 11 can rotate by the action of the airflow.

[0078] Preferably, the angle between the rotation axis Z of the rotating part 11 and the extension direction of the cooling channel 12a is not greater than 10 degrees, that is, the angle between the rotation axis Z of the rotating part 11 and the extension direction of the cooling channel 12a can be equal to 0 degrees (that is, the rotation axis Z can be parallel to the extension direction of the cooling channel 12a), and the angle between the rotation axis Z of the rotating part 11 and the extension direction of the cooling channel 12a can also be greater than 0 degrees and less than or equal to 10 degrees (that is, the rotation axis Z can be roughly parallel to the extension direction of the cooling channel 12a).

[0079] It should be noted that the extension direction of the cooling channel 12a may be parallel to the first direction, that is, the cooling channel 12a may extend along the first direction, and the angle between the extension direction of the cooling channel 12a and the first direction may also be greater than 0 degrees and less than or equal to 10 degrees.

[0080] In order to facilitate the installation of the rotating member 11, for example, refer to Figure 2 and Figure 3 The cooling component 10 may be provided with a rotating shaft 13 , the rotating shaft 13 extends into the cooling channel 12 a , and the rotating member 11 is rotatably provided on the rotating shaft 13 , that is, the rotating member 11 can rotate around the rotating shaft 13 .

[0081] See also Figure 2 and Figure 3 The cooling component 10 may be provided with a mounting bracket 14 at the air outlet end of the cooling channel 12 a . The mounting bracket 14 may be connected to the housing 12 , and the rotating shaft 13 is mounted on the mounting bracket 14 .

[0082] In other embodiments, the mounting bracket 14 may also be disposed at the air intake end of the cooling channel 12a.

[0083] See also Figure 2 For the cooling component 10 in which the angle between the rotation axis Z of the rotating member 11 and the extension direction of the cooling channel 12a is not greater than 10 degrees, it is equivalent to that the angle between the axial center line of the rotating shaft 13 and the extension direction of the cooling channel 12a is also not greater than 10 degrees.

[0084] See also Figure 2 , Figure 5 , Figure 7 , Figure 8 One rotating member 11 or multiple rotating members 11 may be arranged on the rotating shaft 13 .

[0085] When the number of the rotating member 11 is greater than one, the cooling component 10 may be as follows: Figure 7 and Figure 8 As shown, only one rotating shaft 13 is provided, and all rotating members 11 can be provided on the same rotating shaft 13, or the cooling component 10 can also be provided with multiple rotating shafts 13, and at least one rotating member 11 is provided on each rotating shaft 13. However, providing all rotating members 11 on the same rotating shaft 13 can not only facilitate the installation of the rotating members 11, but also facilitate the airflow to pass through the cooling channel 12a.

[0086] See also Figure 5 , the length H of the rotating member 11 along the extension direction of the rotation axis Z can be designed as needed. For example, the length H of the rotating member 11 along the extension direction of the rotation axis Z can be 3mm to 20mm (including the end value), for example, the length H can be 3mm, 5mm, 10mm, 12mm, 15mm, 20mm, etc. However, when the length H is greater than 13mm, the diffusion path of the aerosol is longer and the suction resistance is relatively large. When the length H is less than 5mm, the aerosol diffusion path is too short and the cooling effect is poor. Therefore, preferably, the length H of the rotating member 11 along the extension direction of the rotation axis Z can be 5mm to 13mm (including the end value).

[0087] See also Figure 6 , the maximum diameter D of the rotating member 11 rotating around the rotation axis Z can also be designed as needed. For example, the maximum diameter D of the rotating member 11 rotating around the rotation axis Z can be 3mm~10mm (including the endpoint values), for example, the maximum diameter D can be 3mm, 5mm, 8mm, 10mm, etc. However, when the maximum diameter D is less than 4mm, the suction resistance is large and the suction experience is poor. When the maximum diameter D is greater than 9mm, the suction feeling is weak and the suction experience is also poor. Therefore, preferably, the maximum diameter D of the rotating member 11 rotating around the rotation axis Z can be 4mm~9mm (including the endpoint values), and more preferably, the maximum diameter D of the rotating member 11 rotating around the rotation axis Z can be 5mm~8.5mm (including the endpoint values).

[0088] The cooling component 10 of the embodiment of the present application is provided with a rotating part 11 and a shell 12 having a cooling channel 12a, and the rotating part 11 is arranged in the cooling channel 12a of the shell 12. The rotating part 11 can be rotated by the action of the airflow during the suction process of the aerosol generating product. The rotating part 11 converts the internal energy of the aerosol into kinetic energy during the rotation process, and promotes sufficient heat exchange between the aerosol and the external airflow, thereby reducing the temperature of the aerosol. The cooling component 10 has a simple structure and a good cooling effect, and can effectively improve the comfort of the user's suction. In addition, the rotating part 11 can not only break up and reshape the aerosol during the rotation process, so that the aerosol forms a suitable particle size to improve the taste, but also separate the light and heavy components in the aerosol, so that the heavy components stay in the cooling channel 12a, so as to reduce the harm of the aerosol to the human body.

[0089] As for the aerosol generating matrix segment 20 of the embodiment of the present application, since the aerosol generating matrix segment 20 is a porous structure, the aerosol extraction efficiency is relatively high, and the flow rate of the airflow carrying the aerosol into the cooling channel 12a is relatively fast. Therefore, the aerosol generating matrix segment 20 cooperates with the cooling component 10 to achieve a better cooling effect.

[0090] It should be noted that the cooling component 10 of the embodiment of the present application is not limited to being used in conjunction with the aerosol generating matrix segment 20 of the embodiment of the present application. According to design requirements, the cooling component 10 can also be used in conjunction with other types of aerosol generating matrix segments 20 (such as thin sheet, filament or loose particle aerosol generating matrix segments 20), which is not limited here.

[0091] In one embodiment, please refer to Figure 3 and Figure 4 For the convenience of description, a rotating member 11 of a certain structure may be referred to as a first rotating member 11a. The first rotating member 11a includes a main body 11a1 and a plurality of blades 11a2. The plurality of blades 11a2 are arranged around the outer periphery of the main body 11a1.

[0092] The number of blades 11a2 is not limited, but when the number of blades 11a2 is less than 3, after the aerosol passes through the cooling component 10, the particle size is 1nm to 300nm (including the endpoint value), the color of the aerosol is cyan or blue, and the taste of the entrance is relatively poor. When the number of blades 11a2 is greater than 7, after the aerosol passes through the cooling component 10, the particle size is greater than 0.9μm, and the particle size of the aerosol is too large, and it is easy to settle inside the aerosol generating product, thereby causing a decrease in the utilization rate of the aerosol. Therefore, preferably, the number of blades 11a2 can be 3 to 7 (including the endpoint value), for example, the number of blades 11a2 can be 3, 4, 5, 7, etc. More preferably, the number of blades 11a2 can be 3 to 5 (including the endpoint value).

[0093] See also Figure 7 and Figure 8 When the cooling component 10 is provided with a plurality of first rotating members 11a, the number of blades 11a2 of all the first rotating members 11a may be the same, or the number of blades 11a2 of at least two first rotating members 11a may be different, for example, Figure 7 The number of blades 11a2 of the two first rotating members 11a shown is 3. Figure 8 Among the three first rotating members 11 a shown, two of the first rotating members 11 a have four blades 11 a 2 , and the third first rotating member 11 a has three blades 11 a 2 .

[0094] See also Figure 5 , the blade 11a2 can be tilted relative to the rotation axis Z of the first rotating member 11a. When the tilt angle θ of the blade 11a2 relative to the rotation axis Z is too small or too large, the efficiency of converting the internal energy of the aerosol into kinetic energy is relatively low. Therefore, preferably, the tilt angle θ of the blade 11a2 relative to the rotation axis Z can be 1° to 45° (including the endpoint values), for example, the tilt angle θ can be 1°, 15°, 10°, 20°, 30°, 40°, 45°, etc. More preferably, the tilt angle θ of the blade 11a2 relative to the rotation axis Z can be 20° to 35° (including the endpoint values).

[0095] Taking the example of setting multiple first rotating parts 11a on the same rotating shaft 13, in a specific embodiment, the angle between the axial center line of the rotating shaft 13 and the extension direction of the cooling channel 12a is equal to 10 degrees, and three first rotating parts 11a are set on the rotating shaft 13. The length of the first rotating part 11a along the extension direction of the rotation axis Z is 15mm, and the rotation diameter of the first rotating part 11a is 7.2mm. Each first rotating part 11a has three blades 11a2, the material of the blades 11a2 is iron, and the inclination angle of the blades 11a2 relative to the rotation axis Z is 45°. The aerosol generating product with the cooling component 10 is inserted into the aerosol generating device for heating. After the aerosol generating matrix segment 20 is heated, a higher temperature aerosol is generated. During the user's inhalation process, the airflow carries the higher temperature aerosol into the cooling channel 12a to rotate the first rotating member 11a. During the rotation process, the first rotating member 11a converts the internal energy of the aerosol into kinetic energy, and the temperature of the aerosol is reduced. The aerosol flowing out of the cooling channel 12a is tested, and the test results are: the temperature of the aerosol is less than 45°C, and the particle size of the aerosol is 0.56μm to 0.7μm. Compared with the aerosol generating product without the cooling component 10, the temperature drops by more than 15°C, and the user will not feel the mouth is hot when inhaling, and the inhalation experience is better.

[0096] In another specific embodiment, the angle between the axial center line of the rotating shaft 13 and the extension direction of the cooling channel 12a is equal to 10 degrees, and three first rotating members 11a are arranged on the rotating shaft 13. The length of the first rotating member 11a along the extension direction of the rotation axis Z is 13 mm, and the rotation diameter of the first rotating member 11a is 6.5 mm. Each first rotating member 11a has four blades 11a2, and the material of the blades 11a2 is polyamide resin, and the inclination angle of the blades 11a2 relative to the rotation axis Z is 35°. The other structures of the aerosol generating product with the cooling component 10 are the same as those of the aerosol generating product described in the previous specific embodiment. Using the same detection method as the previous specific embodiment, the detection results are: the temperature of the aerosol is less than 45°C, and the particle size of the aerosol is 0.6μm to 0.75μm. Compared with the aerosol generating product without the cooling component 10, the temperature drops by more than 15°C, and the user will not feel the mouth is hot when inhaling, and the inhalation experience is better.

[0097] In another embodiment, see Fig. 9 and Fig.10 For the convenience of description, the second structural form of the rotating member 11 can be called the second rotating member 11b. The second rotating member 11b is columnar, and has a plurality of spiral grooves 11b1 spaced apart on its outer wall. Each spiral groove 11b1 runs through the opposite ends of the axial direction of the second rotating member 11b. The axial direction of the second rotating member 11b is actually the extension direction of the rotation axis Z of the second rotating member 11b.

[0098] The curvature of at least a portion of the spiral groove 11b1 along the extension direction is not zero. For example, see Fig. 9 Along the extension direction of the spiral groove 11b1, the entire spiral groove 11b1 can be in a spiral shape with a non-zero curvature. In other implementations, the spiral groove 11b1 can have a non-zero curvature in a portion of the region along the extension direction, while the curvature in another portion of the region is zero, that is, the other portion of the region can extend in a straight line.

[0099] The number of spiral grooves 11b1 is not limited, but when the number of spiral grooves 11b1 is too small, the efficiency of converting the internal energy of the aerosol into kinetic energy is low, and when the number of spiral grooves 11b1 is too large, the aerosol interception rate is large, therefore, preferably, the number of spiral grooves 11b1 can be 2 to 7 (including the endpoint values), for example, the number of spiral grooves 11b1 can be 2, 4, 5, 7, etc. More preferably, the number of spiral grooves 11b1 can be 3 to 5 (including the endpoint values).

[0100] When the cooling component 10 is provided with a plurality of second rotating members 11 b , the number of the spiral grooves 11 b 1 of all the second rotating members 11 b may be the same, or the number of the spiral grooves 11 b 1 of at least two second rotating members 11 b may be different.

[0101] Taking the cooling component 10 with a second rotating member 11b as an example, in a specific embodiment, the angle between the axial center line of the rotating shaft 13 and the extension direction of the cooling channel 12a is equal to 10 degrees, the length of the second rotating member 11b along the extension direction of the rotation axis Z is 12mm, the rotation diameter of the second rotating member 11b is 7.2mm, and the second rotating member 11b has four spiral grooves 11b1. The other structures of the aerosol generating product with the cooling component 10 are the same as the aerosol generating product described in the previous specific embodiment. Using the same detection method as the previous specific embodiment, the detection results are: the temperature of the aerosol is less than 45°C, and the particle size of the aerosol is 0.44μm to 0.68μm. Compared with the aerosol generating product without the cooling component 10, the temperature drops by more than 15°C, and the user will not feel the mouth is hot when inhaling, and the inhalation experience is better.

[0102] It should be noted that when the number of the rotating member 11 provided in the cooling component 10 is greater than one, the rotating member 11 is not limited to adopting only one structural form, and the rotating member 11 can be a combination of multiple different structural forms, for example, see Fig.11 and Fig.12 The cooling component 10 may be provided with a first rotating member 11a and a second rotating member 11b at the same time.

[0103] For a cooling component 10 having a rotating shaft 13, wherein the angle between the axial center line of the rotating shaft 13 and the extending direction of the cooling channel 12a is not greater than 10 degrees, for example, refer to Fig.11 The first rotating member 11a and the second rotating member 11b may be disposed on the same rotating shaft 13, and the second rotating member 11b may be located on a side away from the air intake end of the cooling channel 12a.

[0104] For example, see Fig.12 The first rotating members 11a may also be respectively disposed on two opposite sides of the second rotating member 11b.

[0105] It should be noted that the first rotating member 11a and the second rotating member 11b are not limited to the above two arrangements. In other embodiments, the first rotating member 11a and the second rotating member 11b may also be arranged in other ways.

[0106] In one embodiment, at least a partial area of ​​the housing 12 may be a light-transmitting structure, and a setting position of the light-transmitting structure at least corresponds to a setting position of the rotating member 11 .

[0107] The light-transmitting structure refers to a structure that allows light to pass through so that the user can see the inside of the cooling channel 12a. According to design requirements, part of the housing 12 may be a light-transmitting structure, which is equivalent to a light-transmitting window being separately provided on the housing 12, or the entire housing 12 may be a light-transmitting structure.

[0108] To facilitate processing and manufacturing, the entire housing 12 may adopt a light-transmitting structure. For example, the housing 12 may be made of transparent paper materials such as transparent molding paper, polylactic acid film, and cellophane.

[0109] The setting position of the light-transmitting structure at least corresponds to the setting position of the rotating member 11, which means that the user can see the rotating member 11 in the cooling channel 12a through the light-transmitting structure. Therefore, during the user's inhalation process, the user can watch the rotating rotating member 11, so as to bring a visual experience to the user.

[0110] In one embodiment, please refer to Figure 2 The side wall of the shell 12 is provided with an air hole 12b which is connected with the cooling channel 12a.

[0111] The purpose of providing the air holes 12b is to allow the external airflow to enter the cooling channel 12a from the air holes 12b during the user's inhalation process and mix with the aerosol in the cooling channel 12a.

[0112] The number of the pores 12b may be one or more, and preferably, the number of the pores 12b may be 2 to 12.

[0113] When there are multiple air holes 12 b, the multiple air holes 12 b may be evenly distributed along the circumference of the shell 12 , or may be distributed in other ways, such as randomly distributed.

[0114] There is no limit to the setting position of the air hole 12b on the side wall of the shell 12. For example, the setting position of the air hole 12b can be close to the air inlet end of the cooling channel 12a, or close to the air outlet end of the cooling channel 12a. In other words, the setting position of the air hole 12b can be close to the aerosol generating matrix segment 20, or far away from the aerosol generating matrix segment 20.

[0115] When there are multiple air holes 12b, some of the air holes 12b may be disposed close to the air inlet end of the cooling channel 12a, and another part of the air holes 12b may be disposed close to the air outlet end of the cooling channel 12a.

[0116] The shape of the cross section of the pore 12b is not limited. For example, the shape of the cross section of the pore 12b can be circular, polygonal (including but not limited to triangle, square, prism, etc.), elliptical, racetrack-shaped, irregular-shaped, etc.

[0117] The surface area of ​​the pores 12b can be 0.01 mm2 ~0.2mm 2 (including endpoint values), for example, the hole surface area can be 0.01mm 2 , 0.05mm 2 , 0.1mm 2 , 0.15mm 2 , 0.2mm 2 However, when the surface area of ​​the pores 12b is less than 0.04 mm 2 When the pore surface area is larger than 0.12mm 2 When the ventilation volume is too large, the concentration of the aerosol will be reduced, thereby affecting the inhalation experience. Therefore, preferably, the surface area of ​​the pore 12b can be 0.04mm 2 ~0.12mm 2 (including the endpoint values).

[0118] Since the mouth feel of the aerosol is relatively poor when the particle size of the aerosol is 1nm to 300nm (including the endpoint value), the air hole 12b is provided so that the external airflow can enter the cooling channel 12a from the air hole 12b and mix with the aerosol in the cooling channel 12a under the action of the rotating member 11. Thus, not only the uniformity of the mixing of the aerosol and the airflow can be improved, and the distribution of the aerosol can be made more uniform, but also the particle size of the aerosol can be controlled within the range of 0.38μm to 0.78nm (including the endpoint value), thereby better improving the user's smoking experience.

[0119] In addition, when the particle size of the aerosol is 1nm~300nm, the color of the aerosol is cyan or blue, and within the particle size range, the smaller the particle size, the more obvious the blue color; when the particle size of the aerosol is 0.38μm~0.78nm, the color of the aerosol is white, and within the particle size range, the larger the particle size, the more obvious the white color. Therefore, for at least a portion of the shell 12, an aerosol generating matrix segment 20 with a light-transmitting structure is used. By setting the air hole 12b, it can also ensure that the aerosol in the cooling channel 12a can appear white, thereby enhancing the user's visual experience.

[0120] In one embodiment, please refer to Figure 1 and Figure 2 The aerosol generating product further includes a functional segment 30 , which is disposed at one end of the cooling component 10 away from the aerosol generating substrate segment 20 , and the functional segment 30 includes at least a filtering segment 31 .

[0121] The filter segment 31 is used to contact with the user's oral cavity when the user inhales, so as to filter the aerosol.

[0122] The material of the filter section 31 includes but is not limited to one or more combinations of PE (polyethylene), PLA (Polylacticacid), PBAT (butyleneadipate-co-terephthalate), PP (Polypropylene), acetate fiber, and acrylic fiber materials.

[0123] It should be noted that the aerosol generating product relies on the aerosol generating substrate segment 20 to generate aerosol, and the functional segment 30 does not generate aerosol.

[0124] In some embodiments, the aerosol generating product may not have the functional segment 30. For example, the aerosol generating device may be provided with a nozzle, which may be reusable or disposable. The nozzle is used in conjunction with the aerosol generating product without the functional segment 30 to replace the functional segment 30.
