Description

Technical Field

[0001] This application relates to the field of aerosol supply, and more particularly to an aerosol supply system for a mouthpiece and cartridge of an aerosol supply system. Background Technology

[0002] Aerosol supply systems are known to generate aerosols for users to inhale by heating but not burning aerosol-generating materials. Providing a similar smoking experience to traditional cigarettes as an alternative has been a long-standing industry goal. However, current aerosol supply systems do not yet offer the same smoking experience as traditional cigarettes and require further improvement. Utility Model Content

[0003] As described in the background section, the current aerosol supply system provides a vaping experience that differs from traditional cigarettes and needs further improvement. Research has found that the mouthpiece, which comes into direct contact with the user's lips, is one factor contributing to this difference: traditional cigarette filters are generally made of paper-wrapped cotton, making them flexible. However, the mouthpieces used in current aerosol supply systems are made of harder materials, resulting in a significantly different feel compared to traditional cigarette filters. Furthermore, the shape of a user's lips varies with each puff. Due to their higher hardness, current mouthpieces have poor deformation capabilities and cannot deform according to the user's lip shape like traditional cigarette filters. This leads to significant variations in the contact area between the mouthpiece and the user's lips between puffs, resulting in low consistency between different puffs in the aerosol supply system. Therefore, this application provides a mouthpiece for an aerosol supply system, a cartridge with the mouthpiece, and an aerosol supply system, aiming to provide users with a vaping experience similar to or even closer to that of traditional cigarettes.

[0004] In a first aspect, this application discloses a nozzle for an aerosol supply system, the nozzle comprising: an airflow channel for aerosol to pass through; an air outlet located at the outlet end of the airflow channel; the nozzle having a first portion having a Shore A hardness in the range of 45-85, and at least a portion of the outer surface of the nozzle being formed by the first portion.

[0005] The mouthpiece has a first portion with a Shore A hardness between 45 and 85, meaning that at least the first portion of the mouthpiece is flexible. Compared to mouthpieces made entirely of high-hardness materials, a mouthpiece with a first portion is obviously closer to the soft filter of a traditional cigarette, thus providing a similar tactile experience. Furthermore, at least a portion of the mouthpiece's outer surface is formed by the first portion, meaning that at least the area in direct contact with the user's lips is flexible, thereby providing an even better tactile experience similar to a traditional cigarette. Of course, considering the issue of deformation, a lower hardness in the first portion is not necessarily better.

[0006] During different suction cycles, the shape of the user's lips may change. If the nozzle is entirely made of a high-hardness material, the size of the contact area between the user's lips and the nozzle may vary depending on the shape of the user's lips during different suction cycles, resulting in significant differences in suction resistance between different suction cycles. Understandably, in this application, because the nozzle is at least partially flexible and has good deformation force, it can deform accordingly to changes in the shape of the user's lips, thereby reducing the variation in the size of the contact area between the user's lips and the nozzle between different suction cycles, and thus improving the consistency of suction resistance between different suction cycles.

[0007] In at least some embodiments of this application, the Shore A hardness value of the first part is in the range of 50-60.

[0008] In at least some embodiments of this application, the Shore A hardness value of the first part is 55.

[0009] In at least some embodiments of this application, the material of the first part may be selected from at least one of PP, TPU, PU, ​​PLA, and SBR.

[0010] In at least some embodiments of this application, the mouthpiece is formed from the first portion at the end of the air outlet. This arrangement means that the end is flexible. As this is the area that inevitably comes into contact with the user's lips when inhaling, making this end flexible provides the user with a better tactile experience similar to that of a traditional cigarette.

[0011] In at least some embodiments of this application, the first portion has a longitudinally extending region that extends from one end of the mouthpiece's outlet to the other and forms at least a portion of the outer surface. This arrangement means that at least a portion of the longitudinally extending region of the mouthpiece, starting from the outlet end, is flexible. When a user inhales, at least a portion of the longitudinally extending region contacts the user's lips, starting from the outlet end of the mouthpiece. Therefore, providing a flexible longitudinally extending region can offer the user a better tactile experience similar to that of a traditional cigarette.

[0012] In at least some embodiments of this application, the length of the longitudinally extending region is between 2 mm and 12 mm. This length range is based on human lip size and suction experience. It is desirable to provide a reasonably long longitudinally extending region to ensure both the shortest possible contact area between the user's lips and the nozzle, and the longest possible contact area between the user's lips and the nozzle.

[0013] In at least some embodiments of this application, the first part includes at least one layer, and the Shore A hardness of the same layer is the same.

[0014] In at least some embodiments of this application, the first portion includes at least one layer, and portions of the same layer at different locations have different Shore A hardness. Based on this, different properties can be achieved by setting the hardness between different parts of the same layer.

[0015] In at least some embodiments of this application, within the same layer, the Shore A hardness of the portion closer to the outer surface is less than that of the portion farther from the outer surface. This means that the closer the mouthpiece is to the area that directly contacts the lips, the lower its hardness, thereby providing the user with a better tactile experience similar to that of a traditional cigarette; it also means that the farther away from the area that directly contacts the lips, the higher its hardness, thereby providing support to the areas with lower hardness.

[0016] In at least some embodiments of this application, the first part comprises only one layer.

[0017] In at least some embodiments of this application, the first part comprises at least two layers, and at least two different layers have the same Shore A hardness.

[0018] In at least some embodiments of this application, the first portion comprises at least two layers, and the Shore A hardness of at least two different layers is different. Based on this, different properties can be achieved by setting the hardness between the layers.

[0019] In at least some embodiments of this application, the Shore A hardness of the layer closer to the outer surface is less than that of the layer farther from the outer surface. This means that the closer the mouthpiece is to the area that directly contacts the lips, the lower the hardness, thus providing the user with a better feel similar to that of a traditional cigarette; it also means that the farther away from the area that directly contacts the lips, the higher the hardness, thus providing support to the areas with lower hardness.

[0020] In at least some embodiments of this application, the nozzle is formed entirely of the first portion.

[0021] In at least some embodiments of this application, the suction nozzle further includes a second portion for supporting the first portion; the hardness of the second portion is greater than that of the first portion. The second portion helps to reduce or avoid severe deformation of the first portion due to its lower hardness.

[0022] In at least some embodiments of this application, along the longitudinal direction of the nozzle, the end face of the first portion near the air outlet is flush with the end face of the second portion near the air outlet. This helps the second portion provide better support to the first portion at the end near the air outlet.

[0023] In at least some embodiments of this application, along the longitudinal direction of the mouthpiece, the end face of the first portion near the air outlet extends beyond the end face of the second portion near the air outlet. This means that the lower-hardness first portion has a greater probability of contacting the user's lips compared to the higher-hardness second portion, which helps to provide the user with a better tactile experience similar to that of a traditional cigarette.

[0024] In at least some embodiments of this application, along the longitudinal direction of the mouthpiece, the end face of the first portion near the air outlet extends beyond and covers the end face of the second portion near the air outlet. The covered end face means that the second portion, which has higher rigidity, does not contact the user's lips at the end near the air outlet, which helps to provide the user with a better tactile experience similar to a traditional cigarette. Furthermore, in scenarios where the first and second portions are detachably connected, the fact that the second portion does not contact the user's lips allows the second portion to be reused while maintaining hygiene.

[0025] In at least some embodiments of this application, the second portion is at least partially fitted within the first portion. This serves two purposes: firstly, the second portion provides support to the inner surface of the first portion; secondly, the fact that at least a portion of the first portion is closer to the outer surface of the mouthpiece relative to the second portion helps to provide the user with a better tactile experience similar to that of a traditional cigarette.

[0026] In at least some embodiments of this application, the second portion is at least partially fitted within the first portion, and along the longitudinal direction of the mouthpiece, the end face of the first portion near the air outlet extends beyond and covers the end face of the second portion near the air outlet. This allows the second portion to provide support for the inner surface of the first portion; furthermore, at least a portion of the first portion relative to the outer surface of the second portion near the mouthpiece, and the end face of the first portion near the air outlet, has a greater probability of contacting the user's lips, which helps to provide the user with a better tactile experience similar to that of a traditional cigarette.

[0027] In at least some embodiments of this application, the second portion is fitted within the first portion, and the end face of the first portion near the air outlet extends beyond and covers the end face of the second portion near the air outlet. The inner surfaces of the first and second portions define an airflow channel, and the inner surface of the second portion is flush with the inner surface of the first portion near the air outlet. The flush inner surfaces of the airflow channel facilitate smooth airflow through the channel.

[0028] In at least some embodiments of this application, the second portion is at least partially embedded within the first portion. This allows the second portion to provide support to the interior of the first portion.

[0029] In at least some embodiments of this application, a portion of the second portion is sleeved within the first portion, and a portion of the second portion is embedded within the first portion. This allows the second portion to provide support to multiple areas such as the inner surface and interior of the first portion.

[0030] In at least some embodiments of this application, the first portion and the second portion are detachably connected. This detachable connection allows the first portion and the second portion to be replaced respectively.

[0031] In at least some embodiments of this application, at least a portion of the outer surface of the mouthpiece is roughened. On the one hand, the roughened surface allows for closer contact between the mouthpiece and the user's lips, improving the consistency of draw resistance between different puffs; on the other hand, setting the outer surface of the mouthpiece to be roughened makes the mouthpiece more similar to the filter of a traditional cigarette, thereby providing the user with a more tactile experience similar to that of a traditional cigarette.

[0032] In at least some embodiments of this application, the roughness VDI level of the rough surface ranges from level 18 to level 24.

[0033] The second aspect of this application discloses a cartridge for an aerosol supply system. The cartridge includes: a cartridge body, the cartridge body including a liquid storage chamber and an air passage; and a mouthpiece as described in any embodiment of the first aspect above, the mouthpiece being connected to the cartridge body and the airflow channel communicating with the air passage. The liquid storage chamber is used to store liquid aerosol generating material, and the air passage is used for the passage of aerosol.

[0034] In at least some embodiments of this application, the cartridge further includes a support member connected to the mouthpiece and supporting the first part; the hardness of the support member is greater than the hardness of the first part. This supports the first part, preventing or reducing severe deformation of the first part.

[0035] In at least some embodiments of this application, the suction nozzle includes the support member. The support member is the second part of the suction nozzle described above.

[0036] In at least some embodiments of this application, the cartridge body includes the support member, and the support member is configured in the same way or similarly to the second part of the mouthpiece described above.

[0037] In at least some embodiments of this application, the cartridge body includes the support member, which is sleeved inside the mouthpiece and interference-fitted with it. Therefore, the support member not only supports the first part but also connects the mouthpiece and the cartridge body. The support member simultaneously fulfills both supporting and connecting functions, which helps to simplify the cartridge structure.

[0038] In at least some embodiments of this application, the mouthpiece and the cartridge body are non-detachable.

[0039] In at least some embodiments of this application, the mouthpiece is detachably connected to the cartridge body. This detachable connection allows the mouthpiece to be replaced, preventing the entire cartridge from being rendered unusable due to mouthpiece damage, thus extending the overall lifespan of the cartridge. Furthermore, replacing a used mouthpiece ensures hygienic vaping.

[0040] In at least some embodiments of this application, the support member is non-detachably connected to the cartridge body. Specifically, the support member and the cartridge body can be integrally molded to simplify the production and assembly process.

[0041] In at least some embodiments of this application, the support member is detachably connected to the cartridge body. This detachable connection allows the support member to be replaced, preventing the entire cartridge from being rendered unusable due to support member damage, thus extending the overall lifespan of the cartridge. Furthermore, since the support member may come into contact with the user's saliva during use, replacing the used support member ensures hygienic vaping.

[0042] A third aspect of this application discloses an aerosol supply system, the system comprising:

[0043] The smoke cartridges described in the second aspect above;

[0044] And an aerosol supply device for providing power to atomize the aerosol supply material in the cartridge to generate an aerosol.

[0045] In at least some embodiments of this application, the system has a suction resistance variance of less than 35% when applied to aerosol suction.

[0046] In at least some embodiments of this application, the system has a suction resistance variance of less than 30% when applied to aerosol suction.

[0047] In at least some embodiments of this application, the cartridge is detachably connected to the aerosol supply device, allowing the cartridge to be replaced.

[0048] In at least some embodiments of this application, the cartridge and the aerosol supply device are non-detachably connected. Specifically, the cartridge and the aerosol supply device can be integrally formed.

[0049] It should be noted that embodiments or features related to one aspect of this application may be applicable to embodiments of other aspects of this application, or may be combined with embodiments of other aspects of this application, as appropriate. Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application.

[0050] The above-described one or more embodiments of this application have at least one or more of the following beneficial effects:

[0051] In embodiments of this application, the mouthpiece includes a first portion with a Shore A hardness ranging from 45 to 85, meaning the mouthpiece is at least partially flexible. On one hand, a flexible mouthpiece more closely resembles the soft filter of a traditional cigarette, thus providing the user with a similar tactile experience. On the other hand, a flexible mouthpiece has good deformation capacity, allowing it to deform according to the shape of the user's lips, thereby reducing variations in the contact area between the user's lips and the mouthpiece between different puffs, and improving the consistency of draw resistance across different puffs. This provides the user with a smoking experience similar to or even closer to that of a traditional cigarette.

[0052] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0114] Aerosol forming agent materials may include one or more components capable of forming aerosols. In some embodiments, aerosol forming agent materials may include one or more of the following: glycerol, propylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, 1,3-butanediol, erythritol, meso-erythritol, ethyl vanillate, ethyl laurate, diethyl octanoate, triethyl citrate, triacetin, a mixture of glycerol diacetate, benzyl benzoate, benzyl phenyl acetate, glyceryl tribocate, lauryl acetate, lauric acid, myristic acid, and propylene carbonate.

[0115] Functional materials

[0116] The other or more functional materials may include one or more of pH adjusters, colorants, preservatives, binders, fillers, stabilizers and / or antioxidants.

[0117] matrix

[0118] The material may be present on or within a carrier to form a matrix. The carrier may be, or include, for example, paper, cardboard, cardboard, reconstituted materials, plastic materials, ceramic materials, composite materials, glass, metal, or metal alloys. In some embodiments, the carrier includes a receptor. In some embodiments, the receptor is embedded within the material. In some alternative embodiments, the receptor is located on one or both sides of the material.

[0119] Consumables

[0120] Consumables are articles comprising or composed of aerosol-generating materials, some or all of which are intended to be consumed by a user during use. Consumables may include one or more other components, such as an aerosol-generating material storage area, an aerosol-generating material delivery component, an aerosol-generating area, a housing, packaging paper, a nozzle, a filter, and / or an aerosol modifier. Consumables may also include an aerosol generator, such as a heater, which releases heat during use to cause the aerosol-generating material to generate an aerosol. The heater may, for example, comprise a combustible material, a material that can be heated by electrical conduction, or a sensor.

[0121] receptors

[0122] A sensor is a material that can be heated by being penetrated by a changing magnetic field (such as an alternating magnetic field). A sensor can be a conductive material, such that penetration by a changing magnetic field results in inductive heating of the heating material. A heating material can be a magnetic material, such that penetration by a changing magnetic field results in hysteresis heating of the heating material. A sensor can be both conductive and magnetic, allowing it to be heated by both heating mechanisms. In this paper, a device constructed to generate a changing magnetic field is referred to as a magnetic field generator.

[0123] Aerosol Modifier

[0124] Aerosol modifiers are substances typically located downstream of the aerosol generation region, configured to modify the generated aerosols, for example, by altering their taste, flavor, acidity, or other properties. Aerosol modifiers can be disposed in aerosol modifier release components operable to selectively release the aerosol modifier. For example, aerosol modifiers can be additives or adsorbents. For example, aerosol modifiers may include one or more of fragrances, colorants, water, and carbon adsorbents. For example, aerosol modifiers can be solid, liquid, or gel. Aerosol modifiers can be in powder, filament, or granular form. Aerosol modifiers may not contain filter material.

[0125] Aerosol generator

[0126] An aerosol generator is a device configured to cause the generation of aerosols from an aerosol-generating material. In some embodiments, an aerosol generator is a heater configured to subject the aerosol-generating material to heat energy in order to release one or more volatiles from the aerosol-generating material to form an aerosol. In some embodiments, an aerosol generator is configured to cause the generation of aerosols from an aerosol-generating material without heating. For example, an aerosol generator may be configured to subject the aerosol-generating material to one or more of vibration, increased pressure, or electrostatic energy.

[0127] This disclosure relates to aerosol delivery systems (which may also be referred to as vapor delivery systems), such as aerosol sprayers or electronic cigarettes. In the following description, the terms "electronic cigarette" or "electronic cigarette" may sometimes be used, but it will be understood that this term is used interchangeably with aerosol delivery systems / devices and electronic aerosol delivery systems / devices. Furthermore, as is common in the art, the terms "aerosol" and "vapor," as well as related terms such as "evaporation," "atomization," and "aerosolization," are generally used interchangeably.

[0128] Aerosol delivery systems (electronic cigarettes) typically (though not always) comprise modular components, including reusable device parts and replaceable (disposable / consumable) cartridge parts. Typically, the replaceable cartridge part will include aerosol generating material and an vaporizer (which may be collectively referred to as an "atomizer"), and the reusable device part will include a power source (e.g., a rechargeable power supply) and control circuitry. It will be understood that these different parts may include additional components depending on their function. For example, the reusable device part will typically include a user interface for receiving user input and displaying operational status characteristics, and the replaceable cartridge device part may include, in some cases, a temperature sensor to aid in temperature control. The cartridge is electrically and mechanically connected to the control unit for use, for example, using threads, bayonet connections, or magnetic connections with suitably arranged electrical contacts. When the aerosol generating material in the cartridge is depleted, or when the user wishes to switch to a different cartridge with a different aerosol generating material, the cartridge can be removed from the reusable part, and a replacement cartridge can be attached to its appropriate position. Systems and devices that conform to this type of two-piece modular configuration can generally be referred to as two-piece systems / devices.

[0129] Electronic cigarettes typically have a generally elongated shape. For the sake of specific examples, some embodiments of this disclosure will be considered to include such a generally elongated two-piece system employing a disposable cartridge. However, it will be understood that the basic principles described herein can be equally applied to different constructions, such as single-piece systems or modular systems comprising more than two components, refillable devices and single-use disposable items, as well as other overall shapes, such as high-performance devices based on a so-called box-shaped pattern that typically has a box-like shape. More generally, it will be understood that some embodiments of this disclosure are based on aerosol delivery systems that are operatively configured to provide the functionality according to the principles described herein, and the construction aspects of the system configured to provide the functionality according to some embodiments of this disclosure are not of primary importance.

[0130] As mentioned earlier, the current aerosol supply system's mouthpiece, with its different filter design compared to traditional cigarettes, negatively impacts the user's vaping experience. Therefore, this application creatively provides a mouthpiece for an aerosol supply system. By incorporating a first portion of the mouthpiece with a Shore A hardness in the range of 45-85, the mouthpiece becomes flexible, providing the user with a soft touch and better draw resistance consistency based on this flexibility.

[0131] The following detailed description of the mouthpiece, cartridge, aerosol supply system, and mouthpiece manufacturing method of this application will be provided through specific embodiments.

[0132] Example 1

[0133] Embodiment 1 of this application provides a nozzle for an aerosol supply system. For example... Figures 1 to 9 As shown, the suction nozzle 10 is generally cylindrical. In alternative embodiments, the suction nozzle 10 may also be other shapes, such as elliptical. The suction nozzle 10 is oriented along its longitudinal direction ( Figure 3 The nozzle 10 (shown in the Y direction) has a proximal end 11 and a distal end 12 arranged opposite to each other. The nozzle 10 includes an outer surface, at least a portion of which comes into direct contact with the user's lips during suction. Figures 1 to 9 As shown, the outer surface includes a proximal end face 111, a distal end face 112, and an outer peripheral surface 101 extending between the proximal end face 111 and the distal end face 112. In at least some embodiments of this application, the overall thickness of the suction nozzle is 0.5 mm to 1.5 mm. It should be noted that the overall thickness of the suction nozzle here refers to the thickness of the wall forming the airflow channel.

[0134] It should be noted that the longitudinal direction in this application can be the height direction of the suction nozzle 10 (i.e., Figure 3 In some embodiments, the longitudinal length of the nozzle 10 is greater than its transverse length (in the Y direction). Figure 3The longitudinal length (in the X direction) of the nozzle 10 is longer. For example, in one type of pen-type aerosol supply system, the longitudinal length of the nozzle 10 may be longer than its transverse length. In an alternative embodiment, the longitudinal length of the nozzle 10 is shorter than its transverse length. For example, in one type of cartridge-type aerosol supply system, the longitudinal length of the nozzle 10 may be shorter than its transverse length. If the nozzle 10 is cylindrical, then transverse refers to its radial direction.

[0135] like Figures 1 to 9 As shown, the nozzle 10 includes an airflow channel 102, an air inlet 103 located at the upstream end of the airflow channel 102, and an air outlet 104 located at the downstream end of the airflow channel 102.

[0136] The air inlet 103 is configured to allow aerosols to enter the airflow channel 102; the air outlet 104 is configured to allow aerosols to flow out of the airflow channel 102, and when the user inhales, their lips contact the air outlet 104 to inhale the aerosols. Figure 1 , 2 In the illustrated embodiment, the air inlet 103 is located at the distal end of the nozzle 10, and the air outlet 104 is located at the proximal end of the nozzle 10. In an alternative embodiment, the air inlet 103 may be located outside the distal end 12 of the nozzle 10, and the air outlet 104 may be located outside the proximal end 11 of the nozzle 10.

[0137] The airflow channel 102 is configured to allow aerosols entering through the air inlet 103 to flow to the air outlet 104. Figures 1 to 9 In the embodiment shown, the airflow channel 102 extends along the longitudinal direction (height direction) of the nozzle and is generally cylindrical with a circular cross-section. In alternative embodiments, the cross-section of the airflow channel 102 may be other shapes. In at least some embodiments, the inner surface forming the airflow channel 102 is flush to facilitate the smooth passage of aerosols.

[0138] In some embodiments of this application, the longitudinal axis of the generally cylindrical suction nozzle 10 may coincide with the longitudinal axis of the generally cylindrical airflow channel 102. As mentioned above, the suction nozzle 10 and the airflow channel 102 may be shapes other than cylindrical, in which case the longitudinal axis of the suction nozzle 10 and the longitudinal axis of the airflow channel 102 may also coincide. In alternative embodiments, the longitudinal axis of the suction nozzle 10 is offset relative to the longitudinal axis of the airflow channel 102.

[0139] The mouthpiece 10 also includes a first portion 13 having a Shore A hardness range of 45-85. Within this Shore A hardness range, the first portion 13 is flexible, providing the user with a tactile feel similar to or close to that of a traditional cigarette filter, thereby enhancing the user's smoking experience. Simultaneously, within this Shore A hardness range, the first portion 13 will not deform significantly due to excessive softness. In at least some embodiments of this application, the Shore A hardness range of the first portion 13 is 50-60. In further embodiments, the Shore A hardness range of the first portion 13 can be 53-58. In even further embodiments, the Shore A hardness of the first portion 13 is 55. The first portion 13 can be prepared by selecting a material with suitable hardness. In at least some embodiments, the material of the first portion 13 can be selected from at least one of PP, TPU, PU, ​​PLA, and SBR. It is understood that the material selection for the first portion 13 also needs to consider the material's temperature resistance and non-toxicity requirements.

[0140] In some embodiments of this application, the entire suction nozzle 10 is formed of the first portion 13, meaning the entire suction nozzle 10 is flexible. In alternative embodiments, only a portion of the suction nozzle 10 is formed of the first portion 13. Considering that at least a portion of the outer surface of the suction nozzle 10 is the area in direct contact with the user's lips, in this embodiment of the application, at least a portion of the outer surface of the suction nozzle 10 is formed of the first portion, meaning that at least a portion of the outer surface has a Shore A hardness of 45-85, thereby providing the user with a better tactile experience.

[0141] Considering that the air outlet 104 of the suction nozzle 10 will inevitably come into contact with the user's lips during suction, in some embodiments of this application, the area of ​​the suction nozzle 10 at the location of the air outlet 104 is formed by a first portion 13. This area may include only the outer surface at the location of the air outlet 104, or it may include a region of a certain thickness / length extending from the outer surface of the air outlet 104 into the suction nozzle 10. Figures 1 to 9 In the illustrated embodiment, the air outlet 104 is located at the proximal end 11 of the suction nozzle 10, therefore the end of the proximal end 11 where the air outlet 104 is located is formed by the first portion 13. The end of the proximal end 11 may only include the proximal end face 111 of the proximal end 11 ( Figure 2 (As shown). In an alternative embodiment, the end of the proximal end 11 may further include a region (not shown) formed by the proximal end face 111 extending a certain length toward the distal end 12.

[0142] Considering that during user suction, at least a portion of the longitudinal region extending from the air outlet 104 of the nozzle 10 has a high probability of contacting the user's lips, therefore in some embodiments of this application, such as Figure 3 As shown, the nozzle 10 has a longitudinally extending region 105 that extends a certain length from the proximal end 11 where the air outlet 104 is located to the distal end 12. Figure 3The area within the dashed box), this vertically extending area 105 is formed by the first part 13. Figure 3 In the illustrated embodiment, the longitudinally extending region 105 includes a longitudinal outer peripheral surface 1051 (a portion of the outer peripheral surface 101) extending a certain length from the proximal end 11 to the distal end 12, and a longitudinal region 1052 formed by the longitudinal outer peripheral surface 1051 extending a certain thickness into the mouthpiece 10. In an alternative embodiment, the longitudinally extending region 105 may only include the longitudinal outer peripheral surface 1051 extending a certain length from the proximal end 11 to the distal end 12. In a further embodiment of this application, the length of the longitudinally extending region 105 may be set with reference to the length of a conventional cigarette filter. By way of example and not limitation, the length of the longitudinally extending region 105 is 2 mm to 12 mm, and in a further embodiment, the length of the longitudinally extending region may be 4 mm to 8 mm.

[0143] In at least some embodiments of this application, the first portion 13 comprises at least one layer, and portions of the same layer at different locations have different Shore A hardness. In one specific embodiment, portions of the same layer closer to the outer surface have a lower Shore A hardness than portions farther from the outer surface. In an alternative embodiment, the first portion 13 comprises at least one layer, and portions of each layer at different locations have the same Shore A hardness.

[0144] In at least some embodiments of this application, the first portion 13 comprises at least two layers, and at least two different layers of the first portion 13 have different Shore A hardness. In a further embodiment, the Shore A hardness of the layer closer to the outer surface is less than that of the layer farther from the outer surface. As one implementation, the Shore A hardness of all layers of the first portion 13 is different and gradually increases in the direction away from the outer surface.

[0145] It should be noted that, in some embodiments of this application, "near the outer surface" can refer to being near the outer peripheral surface 101 along the cross-sectional direction of the suction nozzle 10. For example... Figure 4 As shown, the first part 13 is specifically a hollow tube with a cavity, the cavity of the first part 13 forming an airflow channel 102. The first part 13 includes a first layer 131 and a second layer 132 stacked along the cross-sectional direction of the nozzle 10, the second layer 132 being closer to the outer peripheral surface 101 of the outer surface of the first layer 131. The hardness of the second layer 132 is less than the hardness of the first layer 131. In an alternative embodiment, "closer to the outer surface" may also refer to being closer to the proximal end face 111 of the nozzle 10 along the longitudinal direction of the nozzle 10.

[0146] In addition to the embodiments mentioned above, in alternative embodiments, the first part 13 comprises at least two layers, all of which have the same Shore A hardness.

[0147] The above describes the relevant settings of the first part 13 of the suction nozzle 10. In at least some embodiments of this application, such as Figures 5 to 9 As shown, the suction nozzle 10 includes a first portion 13 and a second portion 14 with a hardness greater than that of the first portion 13. The second portion 14 is configured to support the first portion 13 to reduce or prevent severe deformation of the first portion 13 due to its low hardness.

[0148] In at least some embodiments of this application, the Brinell hardness of the second portion 14 is 100 to 120. In one specific embodiment, the Brinell hardness of the second portion 14 is 110 to 115.

[0149] like Figures 5 to 7 As shown, the first portion 13 has a first end face 133 near the air outlet 104, and the second portion 14 has a second end face 141 near the air outlet. In at least some embodiments of this application, the first end face 133 and the second end face 141 respectively or together constitute at least a portion of the proximal end face 111 of the proximal end 11 of the nozzle 10.

[0150] exist Figure 5 In the illustrated embodiment, along the longitudinal direction of the nozzle 10, the first end face 133 of the first portion 13 near the air outlet 104 is flush with the second end face 141 of the second portion 14 near the air outlet 104. The first end face 133 and the second end face 141 together form at least a portion of the proximal end face 111 of the nozzle 10. This arrangement helps the second portion 14 to provide better support to the first portion 13 at the end near the air outlet 104.

[0151] and Figure 5 The difference lies in Figure 6 In the illustrated embodiment, along the longitudinal direction of the mouthpiece 10, the first end face 133 of the first portion 13 near the air outlet 104 extends beyond the second end face 141 of the second portion 14 near the air outlet 104. This means that the lower hardness of the first end face 133 has a greater probability of contacting the user's lips compared to the higher hardness of the second end face 141, which helps to provide the user with a better tactile experience similar to that of a traditional cigarette.

[0152] Figure 6 The first end face 133 does not cover the second end face 141. (This is in contrast to the previous sentence.) Figure 6 Different, such as Figure 7As shown, along the longitudinal direction of the mouthpiece 10, the first end face 133 of the first portion 13 near the air outlet 104 extends beyond and covers the second end face 141 of the second portion 14 near the air outlet 104. The covering of the second end face 141 means that the relatively hard second end face 141 does not contact the user's lips, which helps to provide a better tactile experience similar to a traditional cigarette. Furthermore, in scenarios where the first portion 13 and the second portion 14 are detachably connected, the second portion 14 does not contact the user's lips, allowing it to be reused while maintaining hygiene.

[0153] like Figures 5 to 7 As shown, the first portion 13 has a third end face 134 away from the air outlet 104, and the second portion 14 has a second end face 141 away from the air outlet 104. In at least some embodiments of this application, as Figure 5 , 7 As shown, along the longitudinal direction of the nozzle 10, the third end face 134 is flush with the fourth end face 142. In alternative embodiments, such as Figure 6 As shown, the fourth end face 142 extends beyond the third end face 134.

[0154] In at least some embodiments of this application, such as Figures 5 to 7 As shown, the first portion 13 is a hollow tube with a cavity. The longitudinal axis of the cavity of the first portion 13 may coincide with the longitudinal axis of the airflow channel 102. In a further embodiment, the cavity of the first portion 13 defines at least a portion of the airflow channel 102. In an alternative embodiment, the longitudinal axis of the cavity of the first portion 13 may be offset from the longitudinal axis of the airflow channel 102.

[0155] The second part 14 is at least partially fitted within the lumen of the first part 13. On the one hand, this arrangement allows the second part 14 to provide support to the inner surface of the first part 13; on the other hand, this arrangement allows at least a portion of the first part 13 to be closer to the outer peripheral surface of the mouthpiece 10 relative to the second part 14, contributing to a better tactile experience similar to that of a traditional cigarette for the user. As an example and not a limitation, the second part 14 can be as follows... Figure 5 , 7 As shown, it is completely fitted inside the cavity of the first part 13.

[0156] In at least some embodiments of this application, such as Figures 5 to 7 As shown, the second portion 14 is also a hollow tube with a cavity, and the cavity of the second portion 14 defines at least a portion of the airflow channel 102. In an alternative embodiment, the second portion 14 may also be a solid tube. In at least some embodiments of this application, the longitudinal axis of the second portion 14 may coincide with or be offset from the longitudinal axis of the first portion 13.

[0157] In at least some embodiments of this application, the thickness of the first portion 13 is 0.5mm-1.5mm. In one specific embodiment, the thickness of the first portion 13 is 0.5mm to 0.7mm. It should be noted that when the first portion 13 is a hollow tube, the thickness here refers to the wall thickness of the first portion 13. In at least some embodiments of this application, the thickness of the second portion 14 is 0.5mm-1mm. In one specific embodiment, the thickness of the second portion 14 is 0.4mm to 0.7mm. It should be noted that when the second portion 14 is a hollow tube, the thickness here refers to the wall thickness of the second portion 14. When the second portion 14 is a cylindrical solid tube, the thickness here refers to the radius of the second portion 14.

[0158] In an alternative embodiment, the second portion 14 is at least partially embedded within the first portion 13. This allows the second portion 14 to provide support to the interior of the first portion 13. Figure 8 As shown, the second part 14 is completely embedded within the first part 13. In an alternative embodiment, the second part 14 is only partially embedded within the first part 13.

[0159] In another alternative embodiment, such as Figure 9 As shown, the second part 14 includes a sleeve portion 143 fitted inside the cavity of the first part 13 and an insert portion 144 embedded between the inner and outer walls of the first part 13. The insert portion 144 may be formed by a protrusion on the outer surface of the sleeve portion 143. This allows the second part 14 to provide support to multiple areas such as the inner surface and interior of the first part 13.

[0160] In at least some embodiments of this application, the second portion 14 may include at least one layer. The hardness settings within the same layer may be the same or different. In one specific implementation, the hardness of the region near the outer surface of the same layer is lower than the hardness of the region away from the outer surface. When the second portion 14 includes at least two layers, the hardness between different layers may be the same or different. In one specific implementation, the layer near the outer peripheral surface is less hard than the layer away from the outer peripheral surface. In another specific implementation, the layer near the proximal end face is less hard than the layer away from the proximal end face.

[0161] In at least some embodiments of this application, the first portion 13 and the second portion 14 can be a detachable connection. As an example, and not a limitation, the detachable connection can be at least one of a snap-fit, a resilient connection, or an interference fit. For example... Figures 5 to 7In this design, at least one of the first part 13 and the second part 14 can be an elastic element, and the inner diameter of the first part 13 is not greater than the outer diameter of the second part 14, so that the second part 14 is inserted into and securely fitted into the cavity of the first part 13 by elastic compression. The detachable connection allows the first part 13 and the second part 14 to be separated, so that when replacing the nozzle 10 of the aerosol supply system, only the first part 13 or the second part 14 needs to be replaced. This avoids the entire nozzle being scrapped due to damage to only the first part 13 or only the second part 14, thus extending the overall lifespan of the nozzle. Furthermore, when the second part 14 has less or no contact with the user's lips, it is more hygienic than the first part 13; replacing only the first part 13 can reduce costs while maintaining hygiene.

[0162] In at least some embodiments of this application, at least a portion of the outer surface of the mouthpiece 10 is a rough surface (not shown in the figures). In one implementation, the outer surface of the mouthpiece 10 that contacts or has a high probability of contacting the user's lips is set as a rough surface. In a further embodiment, the outer surface formed by at least the first portion 13 is set as a rough surface. On the one hand, the rough surface allows for closer contact between the mouthpiece and the user's lips, improving the consistency of draw resistance between different puffs; on the other hand, setting the outer surface of the mouthpiece 10 as a rough surface makes the mouthpiece 10 more similar to the filter of a traditional cigarette, thereby providing the user with a more tactile experience similar to that of a traditional cigarette.

[0163] In at least some embodiments of this application, the roughness VDI level of the rough surface ranges from level 18 to level 24.

[0164] As an example, and not a limitation, the rough surface in this application can be formed by creating a texture on the outer surface of the nozzle 10, by surface coating, or by roughening. All known methods for forming a rough surface are included within the scope of this application.

[0165] It should be noted that, in Figures 1 to 9 In at least some of the embodiments shown, the airflow channel 102, air inlet 103, air outlet 104, proximal end face 111, and distal end face 112 are defined by a first portion 13, or are jointly defined by the first portion 13 and the second portion 14. It will be understood that, unless otherwise specified, in alternative embodiments, at least one of the airflow channel 102, air inlet 103, air outlet 104, proximal end face 111, and distal end face 112 may also be defined by other portions of the nozzle 10.

[0166] Example 2

[0167] Embodiment 2 of this application provides a smoke cartridge for an aerosol supply system. For example... Figures 10 to 12As shown, the cartridge 20 includes a cartridge body 21, which includes a liquid storage chamber 211 and an air passage 212. The liquid storage chamber 211 is configured to store a liquid aerosol generating material. This aerosol generating material can be heated to generate an aerosol.

[0168] The cartridge also includes a mouthpiece 10', which is the same as or similar to the mouthpiece 10 in the aforementioned embodiment 1. The mouthpiece 10' includes a first part 13', an airflow channel 102', an air inlet 103', and an air outlet 104', wherein the airflow channel 102' is connected to the air passage 212 and is located at the downstream end of the airflow of the air passage 212.

[0169] The mouthpiece 10' is connected to the cartridge body 21. In at least some embodiments of this application, the mouthpiece 10' and the cartridge body 21 are non-detachable. In one implementation, the mouthpiece 10' and the cartridge body 21 may be integrally formed. In alternative embodiments, the mouthpiece 10' and the cartridge body 21 are detachably connected. As an example, and not a limitation, the detachable connection may be at least one of snap-fit, magnetic adsorption, and interference fit. The detachable connection allows the mouthpiece 10' to be replaced, which on the one hand avoids the entire cartridge 20 from being scrapped due to damage to the mouthpiece 10', thereby extending the overall lifespan of the cartridge 20; on the other hand, replacing the used mouthpiece 10' ensures hygienic vaping.

[0170] like Figures 10 to 12 As shown, in at least some embodiments of this application, the cartridge 20 further includes a support member 22 connected to and supporting the mouthpiece 10', wherein the hardness of the support member 22 is greater than the hardness of the first portion 13'. By providing the support member 22, severe deformation of the first portion 13' of the mouthpiece 10' is avoided or reduced.

[0171] In at least some embodiments of this application, similar to Embodiment 1, the support member 22 is a component of the suction nozzle 10'. The relevant settings of the support member 22 can be found in the description in Part 2 of Embodiment 1, and will not be detailed here.

[0172] In alternative embodiments, such as Figures 10 to 12 As shown, the support member 22 is disposed on the cartridge body 21, specifically on the end face of the cartridge body 21 near the proximal end. The arrangement of the support member 22 is the same as or similar to the second part 14 in the above embodiment 1. The relevant settings can be found in the description of the second part of embodiment 1, and will not be described in detail here.

[0173] In at least some embodiments of this application, the support member 22 is fitted inside the mouthpiece 10' and is interference-fitted with the mouthpiece 10'. Therefore, the support member 22 not only supports the mouthpiece 10' but also connects the mouthpiece 10' to the cartridge body 21. The support member 22 simultaneously fulfills both supporting and connecting functions, which helps to simplify the cartridge structure.

[0174] In at least some embodiments of this application, the support member 22 is non-detachably connected to the cartridge body 21. Specifically, the support member 22 and the cartridge body 21 can be integrally formed to simplify the production and assembly process of the cartridge 20.

[0175] In an alternative embodiment, the support member 22 is detachably connected to the cartridge body 21. This detachable connection allows the support member 22 to be replaced, preventing the entire cartridge 20 from being rendered unusable due to damage to the support member 22, thus extending the overall lifespan of the cartridge 20. Furthermore, since the support member 22 may come into contact with the user's saliva during use, replacing the used support member 22 ensures hygienic vaping.

[0176] Example 3

[0177] Embodiment 3 of this application discloses an aerosol supply system. Figures 13 to 15 An aerosol supply system 30 is shown. (For example...) Figure 13 As shown, the aerosol supply system 30 is cylindrical in shape, similar to the shape of a traditional cigarette, to provide users with an overall experience similar to that of a traditional cigarette. In at least some embodiments, the overall length and width (diameter when cylindrical) of the system can be referenced to or as close as possible to the length and width of a traditional cigarette.

[0178] like Figures 13 to 15 As shown, the aerosol supply system 30 includes a cartridge 20', which includes a mouthpiece. The mouthpiece has a first portion with a Shore A hardness in the range of 45-85, and the first portion forms at least a portion of the outer surface of the mouthpiece. For details regarding the cartridge 20', please refer to the description of the cartridge 20 in Embodiment 2 above. For details regarding the mouthpiece, please refer to the descriptions of the mouthpieces 10 and 10' in Embodiments 1 and 2 above, which will not be detailed here.

[0179] like Figures 13 to 15As shown, the aerosol supply system 30 also includes an aerosol supply device 40, which may contain a battery 41 to provide aerosol supply material to the electrically atomized cartridge 20' to generate aerosol. In some embodiments of this application, the cartridge 20' may be detachably connected to the aerosol supply device 40 to allow replacement of the cartridge 20' when it is depleted, thereby extending the overall service life of the aerosol supply system 30. By way of example and not limitation, the detachable connection may be at least one of snap-fit, magnetic adsorption, or interference fit. In alternative embodiments, the cartridge may be non-detachably connected to the aerosol supply device 40, such as through integral molding, to simplify the manufacturing and assembly process.

[0180] The aerosol supply system 30 also includes an atomizing element (omitted in the figure), which is configured to heat the aerosol generating material when energized to produce aerosol. The atomizing element can be built into the cartridge 20' or the aerosol supply device 40, or it can be set up independently of the cartridge 20' and the aerosol supply device 40. This application does not impose specific limitations in this regard.

[0181] In at least some embodiments of this application, the aerosol supply system 30 has a suction resistance variance of less than 35% when applied to aerosol suction. In a further embodiment, the aerosol supply system 30 has a suction resistance variance of less than 30% when applied to aerosol suction.

[0182] Table 1 below shows the suction resistance test data for ten single-port suctions of ten aerosol supply systems with the first part.

[0183] All aerosol supply systems in Table 1 have the following configuration: a nozzle, a first part of which is made of TPU material with a Shore A hardness of 55, and a second part made of PCTG material with a Brinell hardness of 110. The overall shell thickness of the nozzle is 1.1 mm, with the second part nested within the first part; the first part has a thickness of 0.6 mm, and the second part has a thickness of 0.5 mm. The surface roughness of the nozzle of the aerosol supply system is VDI18. The calculated standard deviation of its single-inlet suction is 28.2.

[0185]

[0186] Table 2 below shows the suction resistance test data for ten single-inlet suction tests of ten aerosol supply systems excluding the first part. The ten aerosol supply systems in Table 2 have the following configuration: including a nozzle made of PCTG material with a Brinell hardness of 110, excluding the first part made of TPU material with a Shore A hardness of 55. The overall shell thickness of the nozzle is 1.1 mm. The calculated standard deviation of its single-inlet suction is 58.2.

[0189] As can be seen from Tables 1 and 2, the aerosol supply system, including the nozzle with the first part, improves the consistency of suction resistance between different suctions.

[0190] Example 4

[0191] Embodiment 4 of this application discloses a method for manufacturing a nozzle for an aerosol supply system, the method comprising:

[0192] The first part is manufactured to form at least a portion of the outer surface of the nozzle; the Shore A hardness of the first part is in the range of 45-85.

[0193] In at least some embodiments of this application, the method further includes: manufacturing a second portion to form the nozzle using the first portion and the second portion; the hardness of the second portion is greater than the hardness of the first portion.

[0194] In at least some embodiments of this application, the first part and the second part are integrally formed using a 2K injection molding process to form the nozzle. The 2K injection molding process refers to a process in which two or more materials are sequentially injected into a mold in a single injection molding operation to form a single unit.

Secondary injection molding refers to a process in which a material is first injected into a mold for primary molding, the molded part is removed, and then placed into a secondary molding mold to inject the same or a different material again.

[0196] The process can be simplified by integrally molding the first and second parts using a 2K injection molding process or a two-stage injection molding process, and a stable connection between the first and second parts can be formed.

[0197] In another alternative embodiment, the method includes: injection molding the first portion and the second portion respectively, and forming the nozzle by at least one of the following methods:

[0198] Mechanically assemble the first part and the second part; glue the first part and the second part; weld the first part and the second part.

[0199] In at least some embodiments of this application, the mechanical assembly includes either a detachable mechanical assembly or a non-detachable mechanical assembly. For example, assembly can be achieved through magnetic adsorption, snap-fit, or other similar methods.
