[0002] Smoking articles include smoking articles that form aerosols by ignition and smoking articles that form aerosols by heating without burning. In a typical smoking article that heats without burning, it contains an aerosol-generating substrate that can volatilize when heated to generate an aerosol. The aerosol-generating substrate is heated by an external heat source so that it is heated to a degree just sufficient to emit a fragrance. The aerosol-generating substrate does not burn, but instead loads an atomizer and releases the atomizer through high-temperature heating to form smoke when used.

[0003] In the related art, during the inhalation process, air from the external environment directly enters through the medium segment, causing large changes in the temperature of the medium segment, unstable cracking reactions of the aerosol-generating matrix, and differences in the composition of the generated aerosol, which affects the user experience. Summary of the invention

[0004] In view of this, the embodiments of the present application hope to provide an aerosol generating product, in which the air in the external environment does not directly pass through the medium segment, and the atomization consistency is high, so that the user experience is better.

[0005] To achieve the above objectives, the present application provides an aerosol generating product, comprising:

[0013] In one embodiment, the structure between the inner wall surface and the outer wall surface is a solid structure, and the ventilation hole passes through the inner wall surface and the outer wall surface.

[0014] In one embodiment, an airway groove is provided on the circumferential surface of the functional segment, and the airway groove passes through at least one end of the functional segment, and a gap between the airway groove and the first wrapping segment constitutes a part of the air inlet channel.

[0033] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.

[0034] In the description of this application, the "first direction" orientation or position relationship is based on the attached Figure 1 and Figure 2 Regarding the orientation or positional relationship shown, it should be understood that these orientation terms are only for the convenience of describing 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 should not be understood as a limitation on the present application.

[0035] The present application provides an aerosol generating product. Figures 1 to 9 , comprising a wrapping layer 30, a medium segment 10 and a functional segment 20. The functional segment 20 is disposed at one end of the medium segment 10 along the first direction, and the wrapping layer 30 wraps around the circumferential outer surface of the medium segment 10 and the functional segment 20. That is, the medium segment 10 and the functional segment 20 are respectively located at two ends of the aerosol generating article 100, wherein the medium segment 10 is the distal lip end of the aerosol generating article 100, and the functional segment 20 is the proximal lip end of the aerosol generating article 100.

[0036] The proximal lip end refers to the end of the aerosol generating article 100 that is close to the user when the user uses the aerosol generating article 100 , and the distal lip end refers to the end of the aerosol generating article 100 that is far away from the user when the user uses the aerosol generating article 100 .

[0037] The functional section 20 can be used to cool the aerosol, and the functional section 20 is, for example, a cooling section.

[0038] Of course, the functional section 20 may also have the functions of supporting and / or filtering and / or adjusting the suction resistance.

[0039] The aerosol-generating article 100 relies on the medium segment 10 to generate aerosol, and the functional segment 20 is not used to generate aerosol.

[0040] It should be noted that the aerosol generating product 100 of the embodiment of the present application can be used for inhalation by ignition or by heating without burning. In the embodiment of the present application, the aerosol generating product 100 is used for inhalation by heating without burning as an example.

[0041] The aerosol-generating article 100 is intended for use with an aerosol-generating device.

[0042] The medium segment 10 is used to generate an aerosol when heated for inhalation by a user.

[0043] In the embodiment of the present application, the medium segment 10 is substantially cylindrical, which may be a cylindrical shape (i.e., a circular cross-sectional shape), a prism shape (i.e., a polygonal cross-sectional shape), an elliptical cylinder shape (i.e., an elliptical cross-sectional shape), etc., without limitation.

[0044] The medium segment 10 and the functional segment 20 are separable structures, and the two are not connected together by mechanical, physical structure or adhesive, but the two can be in contact, that is, the medium segment 10 and the functional segment 20 are a combined structure. Therefore, different medium segments 10 and different functional segments 20 can be reasonably matched to meet the different suction needs of customers.

[0045] Exemplary, the medium section 10 is a particle combination, also referred to as a powder combination, a kind of reconstituted tobacco medium, for example, a reconstituted tobacco medium containing components such as smoke-generating agent, tobacco. The medium section 10 is an integrated structure, for example, an integrated structure can be formed by extrusion, injection molding or die-casting molding process. 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 is continuously made into a processing method of various cross-section products or semi-finished products by the mold of the extruder discharge port. The medium structure formed by extrusion molding is strip-shaped. In this way, after the medium section 10 is heated and sucked or stops being heated, it is an integrated medium, and it is not easy to disintegrate and fall, and the problem that the thin sheet, filament or scattered particle medium section 10 in the prior art appears, such as the problem of thin sheet loosening, filamentous component, particle component falling off, being difficult to clean, and the problem of uneven components.

[0046] The interior of the medium section 10 has at least one air passage hole 10a, see Figure 2 , Figures 4 to 9 The airway hole 10a passes through at least one end of the medium segment 10 along the first direction. The airway hole 10a is used to guide the aerosol to the air guide channel 20a.

[0047] The inside of the medium segment 10 has at least one airway hole 10 a . The inside of the medium segment 10 may have one airway hole 10 a , or the inside of the medium segment 10 may have multiple airway holes 10 a .

[0048] It should be noted that the “multiple” mentioned in the embodiments of the present application refers to a number of two or more.

[0049] In some embodiments, the airway holes 10a pass through the same end of the medium segment 10 along the first direction, and the other end is closed.

[0050] In other embodiments, a portion of the airway holes 10a passes through one end of the medium segment 10 along the first direction, and another portion of the airway holes 10a passes through the other end of the medium segment 10 along the first direction.

[0051] For some further embodiments, please refer to Figure 2 , Figures 4 to 9 Each airway hole 10a passes through both ends of the medium segment 10 along the first direction, that is, the airway hole 10a extends along the first direction of the medium segment 10, and the airflow can flow from one end of the medium segment 10 through the airway hole 10a to the other end of the medium segment 10. Preferably, the airway hole 10a is parallel to the central axis of the medium segment 10.

[0052] The hole wall of the airway hole 10a constitutes the inner surface of the medium segment 10. The airway hole 10a can increase the inner surface area of ​​the medium segment 10, facilitate heat transfer, and improve heating efficiency. In addition, the medium segment 10 generates aerosol after heating, and the aerosol is collected in the airway hole 10a and transported to the suction end under the action of the suction negative pressure. The airway hole 10a can reduce the suction resistance of the user and improve the user experience. It should be noted that the suction resistance is positively correlated with the flow resistance of the aerosol. The smaller the flow resistance of the aerosol in the medium segment 10, the smaller the suction resistance experienced by the user. The greater the flow resistance of the aerosol in the medium segment 10, the greater the suction resistance experienced by the user.

[0053] It should be noted that the shape of the airway hole 10a is not limited here. For example, on a plane perpendicular to the first direction of the medium segment 10, the cross-sectional shape of the airway hole 10a includes but is not limited to a circle (such as Figures 4 to 9 ), elliptical, racetrack or polygonal, wherein the polygon includes regular or irregular polygons.

[0054] Among them, the runway shape refers to: a shape similar to an athletics track, composed of two semicircles and two parallel straight edges alternately connected.

[0055] The cross-sectional shape of the airway hole 10 a refers to the cross-sectional shape of the airway hole 10 a cut along a plane perpendicular to the first direction of the medium segment 10 .

[0056] In addition, the cross-sectional shapes of the airway holes 10a can be exactly the same, or the cross-sectional shapes of at least two of the airway holes 10a can be different. For example, the cross-sectional shape of at least one airway hole 10a can be circular, and the cross-sectional shape of at least one airway hole 10a can be polygonal.

[0057] An embodiment of the present application further provides an aerosol generating device for use with the sol generating product provided in the embodiment of the present application. The aerosol generating device includes a heating component (not shown), which is used to heat the medium segment 10 to generate an aerosol.

[0058] The heating methods of the heating component include, but are not limited to, resistance heating, electromagnetic heating, infrared heating, microwave heating or laser heating. Transferring heat in the form of thermal convection means that the heating component is not in contact with the medium segment 10, the heating component first heats the air, and then the hot air bakes and heats the medium segment 10. Thermal conduction means that the heating component is in contact with the medium segment 10 and conducts heat to the medium segment 10. Exemplarily, resistance and electromagnetic heating mainly transfer heat to the medium segment 10 in the form of thermal conduction or thermal convection. Infrared heating, microwave heating or laser heating mainly transfer heat to the medium segment 10 in the form of thermal radiation. That is, the heating component can heat the medium segment 10 in one or more of the three forms of thermal conduction, thermal convection and thermal radiation.

[0059] In the embodiment of the present application, the first direction does not specifically refer to the direction in which the outer contour of the medium segment 10 is the longest. Specifically, the direction in which the aerosol generating article 100 is inserted into the containing chamber and the direction in which the aerosol generating article 100 is taken out of the containing chamber are both parallel to the first direction. The length of the medium segment 10 along the first direction may be longer, shorter, or the same as the length in other directions.

[0060] For example, when the appearance of the medium segment 10 is cylindrical, the first direction is the axial direction of the medium segment 10. It should be noted that even when the axial length of the medium segment 10 is less than its diameter, the first direction of the medium segment 10 is still the axial direction. For another example, when the appearance of the medium segment 10 is a rectangular parallelepiped, the first direction is still the direction defined above, that is, the direction in which the aerosol generating article 100 is taken out of the containing chamber. The first direction of the medium segment 10 can be any direction of the length, width, and height of the rectangular parallelepiped.

[0061] The wrapping layer 30 is wrapped around the circumferential outer surface of the medium segment 10 and the functional segment 20. The wrapping layer 30 provides installation space and protection for the medium segment 10 and the functional segment 20, reduces the probability of damage to the medium segment 10 and the functional segment 20, and the heat generated by the medium segment 10 will not be directly transferred to the user, thereby increasing the reliability of the aerosol generating product 100.

[0062] The wrapping layer 30 may wrap around the entire circumferential outer surface of the medium segment 10 and the functional segment 20 , or may wrap around a portion of the circumferential outer surface of the medium segment 10 and the functional segment 20 .

[0063] It is understandable that the material of the wrapping layer 30 has a certain structural strength to reduce the probability of deformation of the aerosol generating article 100 due to airflow pressure during use.

[0064] The specific material of the wrapping layer 30 is not limited, such as one or more combinations of fiber paper, metal foil, metal foil composite fiber paper, PE (Polyethylene), polyethylene composite fiber paper, PBAT (Poly (butyleneadipate-co-terephthalate, poly (butylene adipate-co-terephthalate)) and the like.

[0065] It should be noted that, when the wrapping layer 30 wraps the entire circumferential outer surface of the functional segment 20, the user can directly hold the wrapping layer 30 in the mouth to inhale the aerosol; when the wrapping layer 30 wraps a portion of the circumferential outer surface of the functional segment 20, the user can directly hold the portion of the functional segment 20 extending beyond the wrapping layer 30 in the mouth to inhale the aerosol. Of course, the user can also provide a nozzle outside the functional segment 20 to inhale the aerosol through the nozzle.

[0066] The functional section 20 has an air guide channel 20a, which is connected to the air inlet channel. The airway hole 10a is used to guide the aerosol to the air guide channel 20a, and the air guide channel 20a is used to guide the airflow for the user to inhale.

[0067] See also Figures 2 to 9 The portion of the wrapping layer 30 protruding from the medium segment 10 along the first direction is the first wrapping segment 31, the functional segment 20 is arranged in the first wrapping segment 31, the first wrapping segment 31 and / or the functional segment 20 defines an air inlet channel, and the air guide channel 20a is connected to the air inlet channel.

[0068] That is, when inhaling, the medium segment 10 is heated and atomized, and the air in the external environment enters the air guide channel 20a through the air inlet channel, entrains the aerosol generated by atomization and flows out to be inhaled by the user. In other words, the air in the external environment will not directly enter the medium segment 10, so that the temperature consistency of the medium segment 10 during atomization can be improved. On the one hand, the functional segment 20 can guide the airflow for the user to use, and on the other hand, it can also reduce the temperature of the aerosol, so that the temperature of the aerosol flowing out of the functional segment 20 is appropriate and can be better used by the user.

[0069] The first wrapping segment 31 and / or the functional segment 20 define the air intake channel, which means that the first wrapping segment 31 may define the air intake channel, the functional segment 20 may define the air intake channel, or the first wrapping segment 31 and the functional segment 20 may jointly define the air intake channel.

[0070] It should be noted that in the embodiment of the present application, the end of the medium segment 10 away from the functional segment 20 is in a closed state, so that when inhaled, sufficient negative pressure can be generated to extract aerosol for the user to use. The closed state includes a completely airtight state, i.e., an oxygen-free state, and also includes a small amount of air permeability, i.e., a hypoxic state.

[0071] The end of the medium segment 10 away from the functional segment 20 is in a closed state. The end of the medium segment 10 away from the functional segment 20 can be self-closed, that is, the medium segment 10 relies on its own structure to achieve a closed state at the end away from the functional segment 20; or the medium segment 10 can be assembled and docked with any structure on the aerosol generating device to achieve a closed state at the end of the medium segment 10 away from the functional segment 20. In this way, during inhalation, the medium segment 10 can be in a negative pressure state to facilitate the extraction of aerosol. In addition, the end of the medium segment 10 away from the functional segment 20 is in a closed state, which can also reduce the probability of residue generated by the atomization of the medium segment 10 flowing out and causing contamination to the heating component or other structures of the aerosol generating device, and the cleaning of the aerosol generating product 100 is simpler and more convenient.

[0072] It is understood that in some embodiments, please refer to Figures 2 to 9 The wrapping layer 30 also includes a second wrapping segment 32, the medium segment 10 is arranged in the second wrapping segment 32, the first wrapping segment 31 and the second wrapping segment 32 together constitute the wrapping layer 30, the first wrapping segment 31 and the second wrapping segment 32 can be an integrally formed structure, that is, the wrapping layer 30 is an integral structure, the first wrapping segment 31 and the second wrapping segment 32 can also be independent components, and the wrapping layer 30 is assembled.

[0073] The aerosol generating product provided in the embodiment of the present application is provided with an air inlet channel on the first wrapping segment 31, or an air inlet channel on the functional segment 20, or the first wrapping segment 31 and the functional segment 20 jointly define an air inlet channel, and the air inlet channel is connected to the air guide channel 20a of the functional segment 20. During the inhalation process, air in the external environment is drawn in from the air inlet channel, and the aerosol generated by the atomization of the medium segment 10 is carried out of the functional segment 20 without being drawn in directly through the medium segment 10. This improves the temperature consistency of the medium segment 10 during atomization, and reduces the probability of different aerosol components being generated due to large changes in the atomization temperature of the medium segment 10 caused by the direct entry of air from the external environment from the medium segment 10. On the one hand, the functional segment 20 can guide the airflow, and on the other hand, it can also cool the aerosol, so that the use temperature of the aerosol is more suitable, thereby improving the user experience. The structural arrangement of the aerosol generating product 100 is reasonable and reliable.

[0074] In the related art, the smoking materials of smoking products are, for example, granular, shredded tobacco, thin sheets, etc., which are formed by integral filling, rolling or gathering. When shredded tobacco smoking products are matched with a central heat source, the central material of the smoking products tends to move upward, resulting in "shred blocking". Granular smoking products are prone to poor uniformity of filling particle shape during production and processing, and the seals are prone to fall off, moisture absorption, and sticking and agglomeration with utensils during use.

[0075] The medium segment 10 provided in the embodiment of the present application is an integrated structure, for example, an integrated structure can be formed by extrusion, die casting or injection molding to improve the uniformity of the density of the medium segment 10, thereby improving the stability of aerosol release and suction. In addition, the mass of the medium segment 10 with an integrated structure is relatively uniform, and when the heating component heats the medium segment 10, it will not squeeze the structure around the medium segment 10, so that the medium segment 10 maintains a relatively uniform matrix density. Furthermore, the medium segment 10 with an integrated structure is not prone to sticking, agglomeration, etc. with the aerosol generating device.

[0076] The specific components of the medium segment 10 are not limited here. For example, in one embodiment, the medium segment 10 may include plant components, auxiliary components, smoke-generating agent components, adhesive components, and flavor components.

[0077] The plant component is used to generate an aerosol when heated. The auxiliary component is used to provide a skeleton support for the plant component. The smoke-generating agent component is used to generate smoke when heated. The adhesive component is used to bond the various raw material components. The flavor component is used to provide a characteristic aroma. In this way, the plant component and the smoke-generating agent component can ensure the amount of aerosol generated, while the flavor component can enhance the release of aroma during the suction process and enhance the user experience. The auxiliary component can not only improve the fluidity of the mixed material, but also make the medium segment 10 porous to facilitate the extraction and flow of the aerosol. The adhesive component ensures that the plant component and the auxiliary component etc. constitute a stable mixture to avoid a loose structure.

[0078] Exemplarily, the plant component can be one or more combinations of powders formed after crushing tobacco raw materials, tobacco leaf fragments, tobacco stems, tobacco dust, and flavor plants. Plant components are the core source of flavor. Endogenous substances in plant components can produce physiological satisfaction for users. Endogenous substances such as alkaloids enter the human blood and promote the pituitary gland to produce dopamine, thereby obtaining physiological satisfaction.

[0079] Exemplarily, 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, talcum powder, 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 medium section 10, thereby increasing the aerosol release rate. 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 plant component powder, reduce the friction between the plant component powders, make the overall density of the plant component powder distribution more uniform, and can also reduce the pressure required for the extrusion molding process and reduce the wear of the die. The emulsifier includes one or more combinations of polyglycerol fatty acid esters, Tween-80, and polyvinyl alcohol. The emulsifier 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 the product.

[0080] Exemplarily, the smoke-generating agent component may include: a monohydric alcohol (such as menthol); a polyhydric alcohol (such as propylene glycol, glycerol, triethylene glycol, 1,3-butylene glycol and tetraethylene glycol); an ester of a polyhydric alcohol (such as triacetin, triethyl citrate, a mixture of diacetin esters, triethyl citrate, benzyl benzoate, glyceryl tributyrate); a monocarboxylic acid; a dicarboxylic 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, a mixture of diacetin esters, diethyl suberate, triethyl citrate, benzyl benzoate, benzyl phenylacetate, ethyl vanillate, glyceryl tributyrate, lauryl acetate) in one or more combinations.

[0081] Exemplarily, the adhesive component is in close contact with the interface of the component raw materials by wetting, generating intermolecular attraction, thereby playing a role in bonding the component raw materials, such as powders, liquids, etc. The adhesive component can be a natural plant extract, a non-ionized modified viscous polysaccharide, including one or more combinations of tamarind polysaccharide, guar gum, and modified cellulose (such as carboxymethyl cellulose). The adhesive is used to bond the particles together, which is not easy to loosen. In addition, it improves the water resistance of the medium segment 10 and is harmless to the human body.

[0082] Exemplarily, the flavor component is used to provide a characteristic aroma, such as hay aroma, roasted sweet aroma, solid or liquid substances of nicotine. The flavor component may include one or more combinations of tobacco or other plants, flavor plant extracts, extracts, essential oils, and absolute oils; the flavor component may include monomeric flavor substances, such as one or more combinations of megastigmatriene, neophytadiene, geraniol, nerol, etc.

[0083] It should be noted that the medium segment 10 is formed with micropores, and the micropores are connected to each other and form micro-airways connected to the airway holes 10a. In other words, the micro-airways are connected to the airway holes 10a, and since the micro-airways are formed by the connection between the micropores, the micropores are connected to the micro-airways. In addition, it can be understood that the connection between the micropores can be that some of the micropores are connected and some of the micropores are not connected; or all the micropores can be connected to each other. For example, in an embodiment in which the medium segment 10 is a particle combination, the gaps between the particles constitute the micropores. The size of the micropores is determined by the gaps between the particles.

[0084] The airway holes 10a and the micro-airways can increase the surface area of ​​the medium segment 10, facilitate heat transfer, and improve heating efficiency. The medium of the medium segment 10 releases aerosols when heated, and is collected to the airway holes 10a through the gaps between the wall materials or the micro-airways. The aerosols released by the atomized medium exposed to the airway holes 10a (i.e., the atomized medium located on the inner wall surface of the airway holes 10a) can be directly released to the airway holes 10a. The aerosols between adjacent airway holes 10a can also circulate with each other through the micro-airways and be transported to the suction end under the action of the suction negative pressure.

[0085] It should be noted that the specific form of the air intake passage is not limited herein. For example, in some embodiments, please refer to Figure 1 , Figure 2 , Figures 5 to 9 The first wrapping section 31 has an air inlet 31a that runs through the first wrapping section 31, and the air inlet 31a constitutes the entrance of the air inlet passage. That is, the air in the external environment enters the air inlet passage through the air inlet 31a on the first wrapping section 31, and then enters the air guide passage 20a through the air inlet passage, and flows out with the aerosol generated by atomization for the user to inhale.

[0086] The number of the air inlet holes 31a is not limited, and may be one, or two or more.

[0087] In some embodiments, the number of the air inlet holes 31a is 4-30, for example, 4, 5, 7, 8, 10, 13, 17, 20, 25, 28, 30, etc.

[0088] It should be noted that if there are too many air inlet holes 31a, the air intake will be too much, the suction resistance will be small, and the aerosol content inhaled will be small. If there are too few air inlet holes 31a, the air intake will be too little, the suction resistance will be large, and the aerosol content inhaled will be small, affecting the user experience.

[0089] In this embodiment, the number of the air inlet holes 31a is appropriate, neither too many nor too few, and the suction resistance is appropriate, so that the aerosol content inhaled by the user is appropriate, thereby enhancing the user's experience.

[0090] For other implementations, see Figure 3 and Figure 4 The circumferential surface of the functional segment 20 is provided with an airway groove 20d, and the airway groove 20d passes through at least one end of the functional segment 20. The gap between the airway groove 20d and the first wrapping segment 31 constitutes at least a part of the air intake channel.

[0091] That is to say, in this embodiment, the air in the external environment can carry the aerosol out of the functional section 20 after passing through the gap between the airway groove 20d and the first wrapping section 31. There is no need to perform a hole punching operation on the functional section 20. The aerosol extraction can be achieved only by relying on the cooperation of the functional section 20's own structure and the air inlet 31a. The structure of the aerosol generating product 100 is simpler and the processing difficulty is small.

[0092] Specifically, the air in the external environment passes through the gap between the airway groove 20d and the first wrapping segment 31, and then extracts the aerosol generated by the medium segment 10 from the vicinity of the interface between the medium segment 10 and the functional segment 20 and flows to the air guide channel 20a, and then carries the aerosol generated by the medium segment 10 out of the functional segment 20.

[0093] It should be noted that, in this embodiment, the wrapping layer 30 does not need to be perforated, and external air directly enters from the gap between the airway groove 20d and the first wrapping section 31, which can further simplify the structure and manufacturing process.

[0094] Of course, in other embodiments, the first wrapping section 31 may also be provided with an air inlet 31a, and the air inlet 31a is provided at a portion of the first wrapping section 31 for covering the airway groove 20d. That is, in this embodiment, after the air in the external environment enters the airway groove 20d through the air inlet 31a, it can carry the aerosol out of the functional section 20.

[0095] It should be noted that the number of the airway grooves 20d is not limited, that is, one airway groove 20d or multiple airway grooves 20d may be provided. When the functional segment 20 is provided with multiple airway grooves 20d, each airway groove 20d is provided at intervals on the circumferential outer surface of the functional segment 20.

[0096] The specific structure of the air guide passage 20a is not limited.

[0097] In some embodiments, the functional segment 20 is formed with a ventilation hole 20b, one end of the ventilation hole 20b passes through the outer circumference of the functional segment 20, and the other end extends toward the inside of the functional segment 20, the ventilation hole 20b constitutes a part of the air intake passage, the ventilation hole 20b is butted with (aligned and connected to) the air intake hole 31a, and the air guide passage 20a is connected to the air intake hole 31a through the ventilation hole 20b. Among them, one end of the ventilation hole 20b passes through the outer circumference of the functional segment 20, and the other end extends toward the inside of the functional segment 20, including the case where the ventilation hole 20b radially penetrates the functional segment 20, and also includes the case where the ventilation hole 20b only passes through the outer wall of the functional segment 20.

[0098] For some examples, see Figures 1 to 5 ,as well as Fig. 9 The functional section 20 is a hollow tubular structure having an inner wall and an outer wall, and the inner wall surrounds a hollow channel 20c.

[0099] See also Figure 2 , Figure 5 and Figure 6 The side wall of the functional section 20 is provided with a ventilation hole 20b, which constitutes a part of the air inlet passage. The ventilation hole 20b at least passes through the outer wall surface, and the air guide passage 20a is connected with the air inlet hole 31a through the ventilation hole 20b. Among them, the hollow passage 20c at least constitutes at least a part of the air guide passage 20a.

[0100] That is to say, the air in the external environment can directly enter the functional section 20 through the ventilation hole 20b after passing through the air inlet 31a, and the aerosol generated after atomization can flow out of the functional section 20 through the hollow channel 20c for the user to inhale. The hollow channel 20c can buffer the aerosol, significantly improving the buffering capacity of the aerosol, so that the aerosol can be released stably, the aerosol generating product 100 has good consistency from mouth to mouth, and can also improve the aerosol flow path, thereby achieving rapid cooling.

[0101] The ventilation hole 20b at least passes through the outer wall surface, and may be the ventilation hole 20b only passes through the outer wall surface, or may be the ventilation hole 20b passing through both the outer wall surface and the inner wall surface. In other words, it includes the case where the ventilation hole 20b radially passes through the functional section 20, and also includes the case where the ventilation hole 20b only passes through the outer wall surface of the functional section 20.

[0102] Exemplarily, the functional segment 20 is a solid acetate structure, and the ventilation hole 20b may only pass through the outer wall surface of the functional segment 20, or the ventilation hole 20b may pass through the outer wall surface and the inner wall surface, that is, radially penetrate the functional segment 20.

[0103] For some examples, see Figure 2 The structure between the inner wall surface and the outer wall surface is a solid structure, and the ventilation hole 20b passes through the inner wall surface and the outer wall surface.

[0104] The solid structure described here may refer to a solid acetate fiber structure, in which the gaps between the fiber bundles of the solid acetate fiber structure form airflow pores, and the external airflow enters the airflow pores inside the functional segment 20 through the air inlet and the ventilation hole 20b, and carries the aerosol in the airflow pores out of the functional segment 20 for the user to inhale. The size of the airflow pores is smaller than the size of the airway hole 10a, and has the function of adjusting the suction resistance. In this embodiment, the airflow pores in the solid acetate fiber structure constitute the air guide channel 20a of the functional segment 20.

[0105] The solid structure may also refer to a hollow tubular structure such as a paper tube or an aluminum foil tube without air flow pores formed inside, and the ventilation hole 20b is set to penetrate the inner wall and the outer wall to connect the hollow channel 20c with the air inlet 31a through the ventilation hole 20b.

[0106] In this embodiment, the ventilation hole 20b passes through both the outer wall and the inner wall. The air in the external environment enters through the air inlet 31a and the ventilation hole 20b and flows out of the functional section 20 from the hollow channel 20c with the aerosol for the user to inhale.

[0107] In a specific embodiment, please refer to Figure 2 The air in the external environment enters the hollow channel 20c through the air inlet 31a and the ventilation hole 20b. Part of the air entering the hollow channel 20c flows to the bottom of the hollow channel 20c, and flows out of the functional section 20 from the hollow channel 20c with the aerosol for the user to inhale.

[0108] It can be understood that in this embodiment, the functional section 20 can be a hollow paper tube structure, or a hollow aluminum foil tube structure, which is light in weight, convenient for reducing the overall weight of the aerosol generating product 100, and can utilize the hollow area therein to reduce the temperature of the aerosol; and the hollow paper tube structure and the hollow aluminum foil tube structure have good heat resistance, are not easily deformed by heat, and can still maintain their shape after receiving heat conduction, which can increase the structural stability of the aerosol generating product 100.

[0109] Of course, the functional section 20 can also be a hollow acetate fiber structure (such as Figure 5 and Fig. 9 ), hollow silica gel structure, hollow PET (polyethylene glycol terephthalate) structure, etc., are not limited here.

[0110] It can be understood that acetate fiber refers to acetate fiber, also known as cellulose acetate or cellulose acetate, which is a chemically modified polymer compound obtained by esterifying the hydroxyl groups in the cellulose molecules with acetate, including diacetate fiber and triacetate fiber, which has good acid and alkali resistance and organic solvent resistance.

[0111] The functional segment 20 of the hollow acetate fiber structure can be a hollow structure formed by arranging a plurality of acetate fiber bundles side by side. The gaps between the bundles of the hollow acetate fiber structure form airflow pores, and the hollow acetate fiber structure has a hollow channel 20c passing through both ends of the hollow acetate fiber structure along the first direction. The aerosol generated by the medium segment 10 can flow out of the hollow acetate fiber structure through the airflow pores and the hollow channel 20c for the user to inhale.

[0112] For some examples, see Figure 5 and Figure 6The functional segment 20 is formed with a ventilation hole 20b, one end of which passes through the outer peripheral surface of the functional segment 20, and the other end extends toward the inside of the functional segment 20. The ventilation hole 20b constitutes a part of the air inlet channel, and the air guide channel 20a is connected to the air inlet hole 31a through the ventilation hole 20b. The external airflow enters the air guide channel 20a inside the functional segment 20 through the air inlet and the ventilation hole 20b, and carries the aerosol in the air guide channel 20a out of the functional segment 20 for the user to inhale.

[0113] See also Figure 6 In this embodiment, the functional segment 20 is, for example, a solid acetate fiber structure, and air flow pores are formed by the gaps between the fiber bundles of the solid acetate fiber structure. The external airflow enters the air flow pores inside the functional segment 20 through the air inlet and the ventilation hole 20b, and carries the aerosol in the air flow pores out of the functional segment 20 for the user to inhale. The size of the air flow pores is smaller than the size of the airway hole 10a, and has the function of adjusting the inhalation resistance.

[0114] In this embodiment, the air flow pores in the solid acetate structure constitute the air guide channel 20 a of the functional section 20 .

[0115] In addition, when the aerosol passes through the airflow pores, the filament-type structure has a large surface area, which can filter the aerosol, thereby filtering the impurities contained in the aerosol, improving the user experience. At the same time, the resistance of airflow suction can be adjusted through the filament-type structure, and the filament-type structure can prevent the condensate formed after the aerosol condenses from flowing out of the aerosol generating product 100 and causing adverse effects on other devices in the aerosol generating device.

[0116] It should be noted that the number, size and depth of the ventilation holes 20b are not limited here and are determined according to specific circumstances. The ventilation rate of the aerosol generating article 100 can be regulated by controlling the number, size and depth of the ventilation holes 20b, and sufficient air can be provided to effectively extract the aerosol generated by the medium segment 10 when heated.

[0117] Exemplarily, the ventilation hole 20b may extend along the radial direction of the functional segment 20 and extend to the central axis of the functional segment 20. In this embodiment, one end of the ventilation hole 20b passes through the outer circumference of the functional segment 20, and the other end extends toward the central axis of the functional segment 20. The ventilation hole 20b may pass through the central axis and then continue to pass through the outer circumference of the other side of the functional segment 20, or multiple ventilation holes 20b may be connected at the central axis.

[0118] For some examples, see Figures 7 to 9The medium segment 10 and the functional segment 20 are spaced apart to form a cavity 100a. For example, there is a space between the medium segment 10 and the functional segment 20, and the internal cavity 100a is formed under the wrapping of the wrapping layer 30 having a certain hardness. The cavity 100a has a large space, which can increase the contact area with the aerosol, so as to reduce the temperature of the aerosol, and is also convenient for storing the aerosol.

[0119] For some examples, see Figures 7 to 9 The first wrapping section 31 is provided with an air inlet 31a through the side wall corresponding to the cavity 100a, and the air inlet 31a constitutes the entrance of the air inlet channel. That is to say, after the air in the external environment enters the cavity 100a through the air inlet 31a, it carries the aerosol and flows out through the functional section 20 for the user to inhale. In this way, the air in the external environment can also promote the cooling effect of the cavity 100a, and can also reduce the probability of the aerosol being deposited on the contact surface between the medium section 10 and the functional section 20. The aerosol extraction rate is high, and the aerosol is first cooled by the cavity 100a and then cooled by the functional section 20, which can make the use temperature of the aerosol more suitable.

[0120] In some embodiments, the functional section 20 is a solid acetate fiber structure, or a polyester resin structure, or a porous filter structure. On the one hand, it can filter impurities or harmful substances contained in the aerosol, adsorb condensate or large particle droplets formed by aerosol condensation, keep the aerosol dry, and improve the user experience. On the other hand, it can also adjust the suction resistance to make the aerosol content generated per unit time more reasonable.

[0121] The material of the functional segment 20 is not limited. For example, the material of the functional segment 20 includes but is not limited to one or more combinations of PE (polyethylene), PLA (Polylactic acid, also known as polylactide), PBAT (Poly (butyleneadipate-co-terephthalate), PP (Polypropylene), acetate fiber, and acrylic fiber materials.

[0122] In some embodiments, the cross-sectional shapes and sizes of the media segment 10 and the functional segment 20 are the same, which is beneficial for the installation and coordination between the media segment 10 and the functional segment 20, and can also reduce the size requirements of the wrapping layer 30, thereby increasing the installation reliability of the aerosol generating article 100.

[0123] For example, in some embodiments, please refer to Figure 8The functional section 20 can be an integral structure formed by extrusion. The integral structure functional section 20 manufactured by the extrusion molding process has the functions of temperature resistance and preventing thermal collapse in addition to the cooling function. Among them, extrusion molding can be, for example, a processing method in which a raw material mixture constituting the functional section 20 is added to an extruder, and the material mixture is pushed forward by the screw through the action between the extruder barrel and the screw, and continuously passes through the mold of the extruder outlet to form various cross-section products or semi-finished products.

[0124] For example, in some embodiments, the composition of the functional segment 20 is the same as that of the medium segment 10. In this way, during use, the functional segment 20 will not bring bad smells and avoid affecting the taste of the aerosol. In addition, the composition of the functional segment 20 is the same as that of the medium segment 10, which is more conducive to the functional segment 20 and the medium segment 10 being manufactured by the same manufacturing process and raw materials, thereby improving production efficiency.

[0125] Of course, in other embodiments, the composition of the functional segment 20 is different from that of the medium segment 10. The functional segment 20 can be made of different materials such as plant materials, polysaccharides, silica gel, resin, etc.

[0126] The functional segment 20 has at least one air guiding channel 20 a inside, and the air guiding channel 20 a passes through at least one end of the functional segment 20 along the first direction.

[0127] The functional segment 20 has at least one air guiding channel 20 a inside. The functional segment 20 may have one air guiding channel 20 a inside, or may have multiple air guiding channels 20 a inside.

[0128] In some embodiments, the air guiding channel 20a passes through the same end of the functional section 20 along the first direction, and the other end is closed.

[0129] In other embodiments, a portion of the air guiding channel 20a passes through one end of the functional segment 20 along the first direction, and another portion of the air guiding channel 20a passes through the other end of the functional segment 20 along the first direction.

[0130] In some other embodiments, please refer to Figure 8 Each air guide channel 20a runs through both ends of the functional segment 20 along the first direction, that is, the air guide channel 20a extends along the first direction of the functional segment 20, and the air flow can flow from one end of the functional segment 20 to the other end of the functional segment 20 through the air guide channel 20a. Preferably, the air guide channel 20a is parallel to the central axis of the functional segment 20.

[0131] It is understandable that the functional segment 20 of the extruded integral structure also has micropores inside, and the micropores are connected to each other to form micro air channels connected to the air guide channel 20a.

[0132] It should be noted that the above-mentioned airway holes 10a and air guide channels 20a are holes in a macroscopic sense, and micropores are holes in a microscopic sense. The cross-sectional area of ​​the airway holes 10a is much larger than that of the micropores.

[0133] Exemplarily, the cross-sectional area of ​​the airway hole 10a and the air guide channel 20a is at least 20 times the cross-sectional area of ​​the micropore. When the size of the micropore remains roughly unchanged, when it is less than 20 times, the size of the airway hole 10a and the air guide channel 20a will be too small, and the aerosol will not be easily released from the inner wall of the airway hole 10a into the airway hole 10a, and it will cause the user's suction resistance to be large, and the user's suction experience will be reduced. Therefore, in this embodiment, when the cross-sectional area of ​​the airway hole 10a is greater than or equal to 20 times the cross-sectional area of ​​the micropore, the rate of aerosol release from the inner wall of the airway hole 10a can be guaranteed, and the suction resistance can also be reduced, thereby improving the user's suction experience.

[0134] In some embodiments, the cross-sectional area of ​​the airway hole 10a is 20 to 60,000 times the cross-sectional area of ​​the micropore. If the cross-sectional area of ​​the airway hole 10a exceeds 60,000 times the cross-sectional area of ​​the micropore, the area of ​​the airway hole 10a will be too large, the overall quality of the generated aerosol will decrease, the utilization rate of the aerosol generation substrate will be low, and the heating rate will be large, and the aerosol will be easily released from the micropore into the environment.

[0135] Exemplarily, the cross-sectional area of ​​the airway hole 10a is 100 to 40,000 times the cross-sectional area of ​​the micropore.

[0136] In some embodiments, the diameter of the airway hole 10a ranges from 0.05 mm (millimeter) to 6 mm. When the diameter of the airway hole 10a is less than 0.05 mm, the processing cost of the medium segment 10 is high and it is easy to have problems such as large suction resistance and low medium utilization. When the diameter of the airway hole 10a is greater than 6 mm, the cross-sectional area is large, the flow rate of the airflow is smaller under the same volume in the suction state, and the aerosol is prone to deposition, resulting in low aerosol utilization.

[0137] The specific value of the aperture of the airway hole 10a is not limited, for example, 0.05mm, 0.1mm, 0.5mm, 1mm, 2mm, 3mm, 5mm, 6mm, etc.

[0138] It should be noted that the aperture of the airway hole 10a refers to its equivalent diameter.

[0139] The equivalent diameter refers to the diameter of a circle with the same cross-sectional area as the object being measured.

[0140] The airway holes 10a and the micro-airways can increase the surface area of ​​the medium segment 10, facilitate heat transfer, and improve heating efficiency. The medium of the medium segment 10 releases aerosols when heated, and is collected to the airway holes 10a through the gaps between the wall materials or the micro-airways. The aerosols released by the atomized medium exposed to the airway holes 10a (i.e., the atomized medium located on the inner wall surface of the airway holes 10a) can be directly released to the airway holes 10a. The aerosols between adjacent airway holes 10a can also circulate with each other through the micro-airways and be transported to the suction end under the action of the suction negative pressure.

[0141] When the functional section 20 is provided with a plurality of air-guiding channels 20a, the aerosol can exchange heat with the pore walls of the air-guiding channels 20a when flowing through the air-guiding channels 20a. The temperature of the aerosol can be effectively reduced by utilizing the multi-air-channel heat exchange.

[0142] The functional segment 20 adjusts the functions of cooling, filtering and adjusting the suction resistance by setting the air guide channel 20a and controlling the design parameters of the air guide channel 20a, for example, by controlling the number of air guide channels 20a of the functional segment 20, the cross-sectional area (hydraulic diameter) of the air guide channel 20a, the cross-sectional area of ​​the functional segment 20 and other parameters.

[0143] It should be noted that the shape of the air guide channel 20a is not limited here. For example, on a plane perpendicular to the first direction of the functional segment 20, the cross-sectional shape of the air guide channel 20a includes but is not limited to a circle (such as Figure 8 ), at least one of an ellipse, a racetrack, a strip, a polygon and a five-pointed star, wherein the polygon includes a regular or irregular polygon.

[0144] The cross-sectional shape of the air guiding channel 20 a refers to the cross-sectional shape of the air guiding channel 20 a cut along a plane perpendicular to the first direction of the functional section 20 .

[0145] In addition, the cross-sectional shapes of the air guiding channels 20a may be exactly the same, or the cross-sectional shapes of at least two of the air guiding channels 20a may be different. For example, the cross-sectional shape of at least one of the air guiding channels 20a may be circular, and the cross-sectional shape of at least one of the air guiding channels 20a may be polygonal.

[0146] In order to facilitate the aerosol generated by the medium segment 10 when heated to flow directly out of the air guide channel 20a of the functional segment 20 for inhalation by the user, illustratively, at least part of the air guide channel 20a is connected to the airway hole 10a. That is, when projected on a plane perpendicular to the first direction of the aerosol generating article 100, at least part of the orthographic projection of the air guide channel 20a and the airway hole 10a overlaps.

[0147] It should be noted that the communication between the air guide channel 20a and the airway hole 10a mentioned here refers to direct communication.

[0148] For example, on a plane perpendicular to the first direction of the aerosol generating article 100, the cross-sectional area of ​​the air guide channel 20a is smaller than the cross-sectional area of ​​the airway hole 10a, or the hydraulic diameter of the air guide channel 20a is smaller than or equal to the hydraulic diameter of the airway hole 10a. In this way, it is beneficial to achieve the functions of cooling and filtering the aerosol and adjusting the inhalation resistance of the aerosol generating article 100.

[0149] In the embodiment of the present application, the hydraulic diameter refers to the ratio of four times the flow cross-sectional area to the circumference.

[0150] It is understandable that the number of air guide channels 20 a is greater than the number of airway holes 10 a , and a large number of air guide channels 20 a with a small cross-sectional area are more conducive to cooling and filtering the aerosol, and adjusting the inhalation resistance of the aerosol generating product 100 .

[0151] Exemplarily, the medium segment 10 and the functional segment 20 are cylinders with the same outer diameter and are coaxially arranged, and the first direction is the axial direction of the medium segment 10 and the functional segment 20. By setting the medium segment 10 and the functional segment 20 to be cylinders with the same outer diameter, and arranging the axial directions of the medium segment 10 and the functional segment 20 in sequence, the structure of the aerosol generating article 100 can be made more compact, and the user's experience is improved. The functional segment structure of the embodiment of the present application is simple, which simplifies the structural design and process flow of the aerosol generating article and reduces the production cost.

[0152] The following is a brief introduction to seven specific embodiments in conjunction with the accompanying drawings.

[0153] First embodiment

[0154] See also Figure 1 and Figure 2 In this embodiment, the aerosol generating article 100 includes a wrapping layer 30, a medium segment 10 and a functional segment 20. The wrapping layer 30 wraps around the circumferential outer surface of the medium segment 10 and the functional segment 20, and the functional segment 20 is located at one end of the medium segment 10 along the first direction. That is, the medium segment 10 and the functional segment 20 are respectively located at two ends of the aerosol generating article 100, wherein the medium segment 10 is the far lip end of the aerosol generating article 100, and the functional segment 20 is the near lip end of the aerosol generating article 100.

[0155] The medium segment 10 and the functional segment 20 are separable structures, that is, the aerosol generating article 100 is a two-section combined structure composed of the medium segment 10 and the functional segment 20 .

[0156] The functional section 20 has an air guide channel 20a, which is connected to the air inlet channel and is used to guide the air flow for the user to inhale.

[0157] The portion of the wrapping layer 30 protruding from the medium segment 10 along the first direction is the first wrapping segment 31. The functional segment 20 is arranged in the first wrapping segment 31. An air intake channel is formed between the first wrapping segment 31 and the functional segment 20. The air guide channel 20a is connected to the air intake channel.

[0158] At least one air passage hole 10a is provided inside the medium segment 10, and the air passage hole 10a passes through at least one end of the medium segment 10 along the first direction.

[0159] Among them, the medium segment 10 is an integrated structure containing a macroscopic and / or microscopic porous structure prepared by processes such as extrusion, injection molding or die-casting. The suction resistance of the medium segment 10 mainly depends on its own porosity, that is, the pore size and number of the airway holes 10a. A functional segment 20 is provided at the upper end. While ensuring the cooling and effective extraction of the amount of smoke, the suction resistance adjustment function is taken into account, so that the suction resistance of the aerosol generating product 100 meets the design requirements.

[0160] The first wrapping section 31 has an air inlet 31a passing through the first wrapping section 31, and the air inlet 31a constitutes the entrance of the air inlet passage. That is, the air in the external environment enters the air inlet passage through the air inlet 31a on the first wrapping section 31, and then enters the air guide passage 20a through the air inlet passage, and flows out with the aerosol generated by atomization for inhalation by the user.

[0161] The functional section 20 is a hollow tubular structure having an inner wall and an outer wall, wherein the inner wall encloses a hollow channel 20c, and the side wall of the functional section 20 is provided with a ventilation hole 20b, which constitutes a part of the air intake channel, and the ventilation hole 20b at least passes through the outer wall, and the air guide channel 20a is connected to the air intake hole 31a through the ventilation hole 20b. Among them, the hollow channel 20c at least constitutes at least a part of the air guide channel 20a.

[0162] The structure between the inner wall and the outer wall is a solid structure, and the ventilation hole 20b passes through the inner wall and the outer wall. The functional section 20 is, for example, a hollow paper tube structure or a hollow aluminum foil tube structure.

[0163] The aerosol flow mode in this embodiment is specifically described. The medium segment 10 has micropores inside, and the micropores are at least partially connected to each other and connected to the first airway hole 10a. When the medium segment 10 is heated, the air in the external environment enters the hollow channel 20c through the air inlet 31a on the first wrapping segment 31 and the ventilation hole 20b set on the side wall of the functional segment 20, and the aerosol generated by atomization flows out for the user to inhale.

[0164] Second embodiment

[0165] See also Figure 5In this embodiment, the structure of the aerosol generating product 100 is substantially the same as that of the first embodiment, and the main differences include: in this embodiment, the functional segment 20 is a tow-type structure, and the tow-type structure is, for example, a hollow acetate fiber structure.

[0166] The ventilation hole 20b penetrates the inner wall surface and the outer wall surface.

[0167] Third embodiment

[0168] See also Figure 6 In this embodiment, the structure of the aerosol generating product 100 is substantially the same as that of the first embodiment, and the main differences include: in this embodiment, the functional segment 20 is a tow-type structure, and the tow-type structure is, for example, a solid acetate fiber structure.

[0169] The functional segment 20 is formed with a ventilation hole 20b, one end of which passes through the outer peripheral surface of the functional segment 20, and the other end extends toward the inside of the functional segment 20. The ventilation hole 20b constitutes a part of the air inlet channel, and the air guide channel 20a is connected to the air inlet hole 31a through the ventilation hole 20b. External airflow enters the air guide channel 20a inside the functional segment 20 through the air inlet and the ventilation hole 20b, and entrains the aerosol in the air guide channel 20a to flow out of the functional segment 20 for the user to inhale.

[0170] The ventilation hole 20 b may extend in the radial direction of the functional segment 20 and extend to the central axis of the functional segment 20 .

[0173] The air inlet hole 31 a passes through the side wall of the first wrapping section 31 corresponding to the cavity 100 a .

[0174] Fifth embodiment

[0175] See also Figure 8 In this embodiment, the structure of the aerosol generating article 100 is substantially the same as that of the fourth embodiment, and the main differences include: in this embodiment, the functional section 20 is an integral structure formed by extrusion.

[0176] The functional segment 20 has at least one air guiding channel 20 a inside, and the air guiding channel 20 a passes through at least one end of the functional segment 20 along the first direction.

[0177] Sixth embodiment

[0180] Seventh embodiment

[0181] See also Figure 3 and Figure 4 In this embodiment, the structure of the aerosol generating article 100 is substantially the same as that of the first embodiment, and the main differences include: in this embodiment, an airway groove 20d is provided on the circumferential surface of the functional segment 20, and the airway groove 20d passes through at least one end of the functional segment 20, and an air inlet hole 31a is provided in the first wrapping segment 31 for covering the portion of the airway groove 20d, and the airway groove 20d defines at least a portion of the air inlet channel.

[0182] That is to say, in this embodiment, after the air in the external environment enters the airway groove 20d through the air inlet hole 31a, it can carry the aerosol out of the functional section 20 without punching holes in the functional section 20. The aerosol extraction can be achieved only by relying on the cooperation between the structure of the functional section 20 itself and the air inlet hole 31a. The structure of the aerosol generating product 100 is simpler and the processing difficulty is small.

[0183] The functional section 20 is a hollow tubular structure having an inner wall surface and an outer wall surface, and the inner wall surface encloses a hollow channel 20c.
