[0026] The application will be described in further detail below with specific embodiments in conjunction with the accompanying drawings.

[0027] The serial numbers for components in this document, such as “first”, “second”, etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. Unless otherwise specified, “connected” and “coupled” in this document, including direct and indirect connections (couplings).

[0028] The heating non-combustion assembly provided by the embodiments of the present application is applied to a heating non-combustion appliance, and is used for realizing heating of an aerosol product.

[0029] The heating non-combustion assembly provided by the embodiments of the present application, as shown in FIG. 1, comprises a heating main body 2 and a suction nozzle 3. The heating main body 2 has a heating cavity 221, which is used for accommodating and heating an aerosol product. The structure of the aerosol product in the embodiments of the present application is different from that of a conventional aerosol product. In the aerosol product in the embodiments of the present application, a cooling section and a filtering section are not arranged.

[0030] In some embodiments, the aerosol product comprises a solid aerosol substrate 4, which can comprise a paper tube and a filamentous, sheet-like or granular smoking solid such as tobacco or aromatic plant material wrapped by the paper tube, or a porous carrier having a smoking agent adsorbed thereon, or a solid cylinder formed by winding a sheet-like structure, or a shaped body formed by extrusion or molding. The solid aerosol substrate 4 can generate an aerosol for a user to use after being heated.

[0031] In the heating non-combustion assembly provided by the embodiments of the present application, as shown in FIG. 1, the suction nozzle 3 is detachably connected with the heating main body 2. The suction nozzle 3 can be directly detachably connected with the heating main body 2. In some embodiments, the suction nozzle 3 can be connected on the heating main body 2 in a threaded connection or a buckle connection manner. Alternatively, the suction nozzle 3 can be indirectly detachably connected with the heating main body 2. In some embodiments, as shown in FIG. 2, the heating non-combustion appliance comprises an appliance main body 1 and the heating non-combustion assembly. The appliance main body 1 comprises a first main body part 11 and a second main body part 12 which are detachably connected. The first main body part 11 can be hingedly connected, threadedly connected or buckled connected with the second main body part 12. The first main body part 11 is connected with the suction nozzle 3, and the second main body part 12 is connected with the heating main body 2. The suction nozzle 3 can be connected with the heating main body 2 through the detachable connection between the first main body part 11 and the second main body part 12. In this way, the suction nozzle 3 can be detached from the entire heating non-combustion appliance. The suction nozzle 3 can be adapted to the heating main body 2 of a plurality of heating non-combustion appliances, so that the cost of the entire heating non-combustion appliance and the use cost of a user can be reduced.

[0032] Referring to FIG. 1 and FIG. 3, the mouthpiece 3 has an air inlet channel 32 and an air outlet channel 33, the air inlet channel 32 and the air outlet channel 33 have the same extension direction, the air inlet channel 32 and the air outlet channel 33 are arranged independently, that is, the air inlet channel 32 and the air outlet channel 33 are physically separated. The mouthpiece 3 also has an air inlet port 312 in communication with the air inlet channel 32, the air inlet port 312 communicates the space outside the mouthpiece 3 with the air inlet channel 32, the air inlet channel 32 is used to communicate with the heating cavity 221 of the heating body 2 when the mouthpiece 3 is engaged with the heating body 2 in the heating non-combustion device, so as to supply air to the heating cavity 221; the air outlet channel 33 is used to communicate with the heating cavity 221 when the mouthpiece 3 is engaged with the heating body 2, so as to discharge the aerosol generated after the solid aerosol substrate 4 in the heating cavity 221 is heated. In this way, the air inlet port 312, the air inlet channel 32 and the air outlet channel 33 are all arranged on the mouthpiece 3, without the need to arrange an air channel for temperature reduction in the appliance body 1, and without the need to arrange a temperature reduction section on the aerosol product, and the mouthpiece 3 can be reused, and the aerosol product is only a solid aerosol product, which helps to reduce the cost of the aerosol product and the use cost of the user.

[0033] In some embodiments, referring to FIG. 1 and FIG. 3, the air inlet channel 32 in the mouthpiece 3 can be arranged around the air outlet channel 33, so that the heat of the aerosol with a higher temperature in the air outlet channel 33 can be transferred to the air inlet channel 32 along the channel wall of the air outlet channel 33 and the channel wall of the air inlet channel 32, and the air entering the air inlet channel 32 from the air inlet port 312 can absorb the heat transferred to the air inlet channel 32, so as to preheat the air flow by the heat in the air outlet channel 33, which helps to improve the utilization efficiency of the heat in the heating body 2 and reduce heat loss. In other embodiments, the air inlet channel 32 in the mouthpiece 3 can also be arranged in parallel with the air outlet channel 33.

[0034] In some embodiments, referring to FIG. 1 and FIG. 3, the mouthpiece 3 includes a cylindrical structure, the extension direction of the cylindrical structure is the same as the extension direction of the air outlet channel 33, the cylindrical wall of the cylindrical structure has a circumferentially arranged interlayer space, the air inlet channel 32 is located in the interlayer space, and the air inlet port 312 is arranged in at least two in the circumferential direction around the air outlet channel 33. Those skilled in the art can understand that the interlayer space is a plurality of air inlet channels that are not connected to each other, each air inlet channel can be in communication with an air inlet port 312, or it can be an annular cavity arranged around the entire air outlet channel 33, which can be in communication with a plurality of air inlet ports 312, and each air inlet port 312 can be arranged in the circumferential direction of the mouthpiece 3.

[0035] In some embodiments, please refer to Figures 1 and 3. The outer peripheral surface of the suction nozzle 3 can be a cylindrical surface, or it can be an arc-shaped surface or a curved surface. The air inlet 312 is disposed on the outer peripheral surface of the suction nozzle 3. The air inlet 312 is located at the end of the air inlet channel 32 facing away from the heating cavity 221 in the extending direction of the air outlet channel 33. In some embodiments, referring to Figures 2 and 3, the suction nozzle 3 has an outwardly protruding portion 31 exposed in the first main body portion 11 of the device body 1. The user's lips can wrap around the outwardly protruding portion 31 to suck out the aerosol flowing out of the air outlet channel 33. The air inlet 312 can be located on the outwardly protruding portion 31, and the air inlet 312 is set close to the first main body portion 11 in the extending direction of the air outlet channel 33. In the extending direction of the air outlet channel 33, the distance between the air inlet 312 and the end of the outwardly protruding portion 31 is not less than 5mm, that is, the distance between the air inlet 312 and the outlet of the air outlet channel 33 in the extending direction of the air outlet channel 33 is not less than 5mm. The distance between the air inlet 312 and the end of the outwardly protruding portion 31 can be 5mm-10mm, such as 5mm, 6mm or 7mm, to ensure that the suction nozzle 3 has a suitable length for the user to hold and to prevent the user's lips from blocking the air inlet 312.

[0036] In other embodiments, the first main body 11 includes a first outer shell, and the suction nozzle 3 also has a mounting portion located inside the first outer shell. The air inlet 312 can be located on the outer peripheral surface of the mounting portion. An opening communicating with the internal space of the first outer shell is also provided on the first outer shell. External ambient temperature air can enter the air intake channel 32 through the opening of the first outer shell and the air inlet 312 of the suction nozzle 3 in sequence. In this structure, the overall length of the protrusion 31 in the extension direction of the air outlet channel 33 can also be not less than 5mm, so as to satisfy that the suction nozzle 3 has a suitable length for the user's lips to hold.

[0037] In some embodiments, referring to Figures 1 and 3, the orientation of the air inlet 312 may be perpendicular to the extension direction of the air outlet channel 33, or the air inlet 312 may be inclined relative to the extension direction of the air outlet channel 33, that is, the angle between the orientation of the air inlet 312 and the extension direction of the air outlet channel 33 may be less than 90°.

[0038] In some embodiments, the air inlet 312 gradually tilts away from the outlet direction of the outlet channel 33 in the direction of airflow intake. This helps to increase the flow rate and intake volume of the airflow entering the air inlet channel 32. By increasing the intake volume, the concentration of aerosol discharged from the outlet channel 33 can be reduced, which can also increase the cooling effect of the aerosol and reduce the suction resistance to a certain extent. The angle between the orientation of the air inlet 312 and the extension direction of the outlet channel 33 can be set to 25°-55°, such as 25°, 55°, or even 35°, 45°, etc.

[0039] In other embodiments, the air inlet 312 can be set to gradually tilt towards the outlet direction of the air outlet channel 33 in the direction of airflow intake. This helps to reduce the flow rate and intake volume of the airflow entering the air inlet channel 32. By reducing the intake volume, the concentration of aerosol discharged from the air outlet channel 33 can be increased, which can also increase the suction resistance to a certain extent to meet the suction needs of different users.

[0040] In some embodiments, referring to Figures 1 and 3, the inlet of the exhaust channel 33 can be directly connected to the heating chamber 221 when the nozzle 3 is engaged with the heating body 2, so as to receive the aerosol discharged from the heating chamber 221. The heating chamber 221 in the heating body 2 can be configured as a cylindrical cavity, which is used to contain the solid aerosol matrix 4. The solid aerosol matrix 4 can be placed in the heating chamber 221 when the nozzle 3 is separated from the heating body 2. After the nozzle 3 is engaged with the heating body 2, the heating body 2 is controlled to heat the solid aerosol matrix 4.

[0041] For the exhaust channel 33, in some embodiments, please continue to refer to Figures 1 and 3. The cross-sectional shape of the exhaust channel 33 can be circular, or elliptical, square or other irregular structure. The exhaust channel 33 includes a variable diameter channel, which can accelerate the discharge of aerosols, promote aerosol agglomeration and prevent aerosol condensation.

[0042] In some embodiments, please continue to refer to Figures 1 and 3. The variable diameter channel of the air outlet channel 33 includes a first transmission section 331 and a second transmission section 332 that are connected. The second transmission section 332 is connected to the end of the first transmission section 331 away from the outlet of the air outlet channel 33 in the extension direction of the air outlet channel 33. The second transmission section 332 is operably connected to the heating chamber 221. The second transmission section 332 is connected to the heating chamber 221 when the nozzle 3 is engaged with the heating body 2 to collect the aerosol generated in the heating chamber 221. The first transmission section 331 is connected to the heating chamber 221 through the second transmission section 332. The heating cavity 221, the first transmission section 331, and the second transmission section 332 all have cross-sections in a plane perpendicular to the extension direction of the air outlet channel 33. In the plane perpendicular to the extension direction of the air outlet channel 33, the cross-sectional area of ​​the second transmission section 332 is larger than the cross-sectional area of ​​the heating cavity 221 and also larger than the cross-sectional area of ​​the first transmission section 331. The cross-sectional area of ​​the first transmission section 331 is smaller than the cross-sectional area of ​​the heating cavity 221. In a structure in which the cross-sectional shape of the air outlet channel 33 and the heating cavity 221 are both circular, the inner diameter of the first transmission section 331 is smaller than the inner diameter of the second transmission section 332. The inner diameter of the first transmission section 331 is also smaller than the inner diameter of the heating cavity 221. The inner diameter of the second transmission section 332 is larger than the inner diameter of the heating cavity 221.

[0043] During the use of the heated non-combustible component, the aerosol generated in the heating chamber 221 can be collected by the second transmission section 332 for buffering and cooling. During suction, the aerosol in the second transmission section 332 is drawn into the first transmission section 331. Since the inner diameter of the first transmission section 331 is smaller than that of the second transmission section 332, the aerosol enters the first transmission section 331 from the second transmission section 332. Due to the reduced flow cross-sectional area, the flow velocity increases according to the continuity equation in fluid mechanics, intensifying the collision of aerosol particles and improving the heat exchange efficiency of the aerosol particles. This further cools the aerosol and improves the user's suction experience. Simultaneously, according to Bernoulli's principle, the increased aerosol flow velocity leads to a decrease in the static pressure of the aerosol, further promoting its acceleration. In other words, a suitable inner diameter ratio between the first transmission section 331 and the second transmission section 332 facilitates accelerated aerosol transport, allowing the aerosol to reach the required flow rate, such as 120-200 mL / s. For example, in some embodiments, the inner diameter ratio of the first transmission segment 331 and the second transmission segment 332 can be set between 1:8 and 1:4, such as 1:8, 1:7, 1:6, 1:5, and 1:4. In other embodiments, the inner diameter ratio of the first transmission segment 331 and the second transmission segment 332 can also be set to other ratios that meet design and usage requirements.

[0044] In some embodiments, referring to Figures 1 and 3, the heated non-combustible assembly includes a heating body 2 and a nozzle 3. The heating body 2 has a heating cavity 221 for containing and heating an aerosol matrix to generate an aerosol. The nozzle 3 has an exhaust channel 33, which includes a first transmission section 331 and a second transmission section 332. The second transmission section 332 is operatively connected to the heating cavity 221 to collect the aerosol generated in the heating cavity 221. The first transmission section 331 is connected to the heating cavity 221 through the second transmission section 332, and the inner diameter of the first transmission section 331 is smaller than the inner diameter of the second transmission section 332.

[0045] Those skilled in the art will understand that the heating body 2 and the suction nozzle 3 can be integrated or separate, as long as the heating chamber 221 and the air outlet channel 33 remain connected during suction.

[0046] During the use of the heated non-combustible component, the aerosol generated in the heating chamber 221 can be collected by the second transmission section 332 for temporary storage and cooling. When suction is performed, the aerosol in the second transmission section 332 is drawn into the first transmission section 331. According to the continuity equation and Bernoulli's principle in fluid mechanics, since the inner diameter of the first transmission section 331 is smaller than that of the second transmission section 332, the flow velocity of the aerosol increases after it is drawn into the second transmission section 332. This intensifies the movement and collision of aerosol particles, improves the heat exchange efficiency of aerosol particles, and further cools the aerosol, thereby improving the problem of high temperature of the sucked-out aerosol and enhancing the user's suction experience.

[0047] In some embodiments, referring to Figures 1 and 3, the second transmission segment 332 has a first variable diameter portion 3321 at one end near the first transmission segment 331. The first variable diameter portion 3321 has a cross-section in a plane perpendicular to the extension direction of the outlet channel 33. The cross-sectional area of ​​the first variable diameter portion 3321 gradually increases from the end connected to the first transmission segment 331 to the end away from the first transmission segment 331 in the extension direction of the outlet channel 33. For example, in a structure where the cross-sectional shape of the outlet channel 33 is circular, the inner diameter of the second variable diameter portion 3331 gradually increases from the end connected to the first transmission segment 331 to the end away from the first transmission segment 331. That is, the inner diameter at the connection between the second transmission segment 332 and the first transmission segment 331 gradually decreases in the direction of airflow, so that the aerosol in the second transmission segment 332 is fully drawn into the first transmission segment 331, which helps to reduce the accumulation and condensation of aerosol in the second transmission segment 332.

[0048] In some embodiments, referring to Figures 1 and 3, the channel wall of the first variable diameter portion 3321 can be arc-shaped, with an arc angle not exceeding 90°. This allows the normal angles corresponding to different positions on the channel wall of the first variable diameter portion 3321 to be different, which helps to increase the disorder of aerosol particle movement during diffusion, thereby increasing the collision probability of aerosol particles, improving heat exchange efficiency, and enhancing the cooling effect. Of course, in other embodiments, the inner cavity of the first variable diameter portion 3321 can also be frustum-shaped, so that the channel wall of the first variable diameter portion 3321 is formed by a series of inclined straight line segments surrounding the axis of the first variable diameter portion 3321.

[0049] In some embodiments, referring to Figures 1 and 3, the variable diameter channel in the exhaust channel 33 further includes a third transmission section 333, which is located downstream of the first transmission section 331. The first transmission section 331 is connected to the outlet of the exhaust channel 33 through the third transmission section 333 to transport the aerosol toward the outlet of the exhaust channel 33. The third transmission section 333 has a cross-section in a plane perpendicular to the extension direction of the air outlet channel 33. In this plane, the cross-sectional area of ​​the third transmission section 333 is larger than that of the first transmission section 331, and the cross-sectional area of ​​the third transmission section 333 can be equal to that of the second transmission section 332. The cross-sectional area of ​​the first transmission section 331 is smaller than that of the heating chamber 221. For example, in a structure where the cross-sectional shape of the air outlet channel 33 is circular, the inner diameter of the second transmission section 332 is equal to the inner diameter of the third transmission section 333, and the inner diameter of the first transmission section 331 is smaller than that of the third transmission section 333. This allows for a relatively larger space within the third transmission section 333, enabling the aerosol to further diffuse and cool after entering the third transmission section 333 from the first transmission section 331, thus further enhancing the cooling effect. Furthermore, the aerosol particles tend to collide and aggregate during diffusion, which helps improve the smoking experience, resulting in a fuller and richer smoking sensation.

[0050] In some embodiments, referring to Figures 1 and 3, the heated non-combustible assembly includes a nozzle 3, which has a suction port and an exhaust channel 33. The suction port is used for the user to inhale, and the exhaust channel 33 is used to transfer aerosol to the suction port when the user inhales, so that the suction port forms the outlet of the exhaust channel 33.

[0051] The exhaust channel 33 includes a first transmission section 331 and a third transmission section 333 that are interconnected. The first transmission section 331 is connected to the suction port through the third transmission section 333 to transport the aerosol towards the suction port. The inner diameter of the third transmission section 333 is larger than that of the first transmission section 331, so that the space inside the third transmission section 333 is relatively large, allowing the aerosol to diffuse and cool after entering the third transmission section 333 from the first transmission section 331, which helps to improve the cooling effect. Furthermore, the aerosol particles are more likely to collide and agglomerate during diffusion, which helps to improve the suction taste, making the suction taste fuller and thicker.

[0052] In some embodiments, referring to Figures 1 and 3, the third transmission segment 333 has a second variable diameter portion 3331 at one end near the first transmission segment 331. The third transmission segment 333 is connected to the first transmission segment 331 through the second variable diameter portion 3331. The second variable diameter portion 3331 has a cross-section in a plane perpendicular to the extension direction of the air outlet channel 33. The cross-sectional area of ​​the second variable diameter portion 3331 gradually increases from the end connected to the first transmission segment 331 to the end away from the first transmission segment 331 in the extension direction of the air outlet channel 33. For example, in a structure where the cross-sectional shape of the air outlet channel 33 is circular, the inner diameter of the second variable diameter portion 3331 gradually increases from the end connected to the first transmission segment 331 to the end away from the first transmission segment 331. The second variable diameter section 3331 is configured such that the connection between the third transmission section 333 and the first transmission section 331 is funnel-shaped in the direction of airflow. When aerosol particles collide with the side wall of the second variable diameter section 3331 during diffusion, their diffusion path can be changed, which helps to increase the probability of aerosol particles colliding and agglomerating, and further improves the smoking experience.

[0053] In some embodiments, referring to Figures 1 and 3, the channel wall of the second diameter-changing portion 3331 can be arc-shaped, with an arc angle not exceeding 90°. This allows the normal angles at different positions on the channel wall of the second diameter-changing portion 3331 to differ, which helps to increase the disorder of aerosol particle movement during diffusion, thereby increasing the probability of aerosol particles colliding and agglomerating during diffusion. Of course, in other embodiments, the inner cavity of the second diameter-changing portion 3331 can also be frustum-shaped, so that the channel wall of the second diameter-changing portion 3331 is formed by a series of inclined straight line segments surrounding the axis of the second diameter-changing portion 3331.

[0054] Those skilled in the art will understand that, for the convenience of aerosol transport and nozzle 3 processing, in some embodiments, the second transport section 332, the first transport section 331, and the third transport section 333 can be coaxially arranged, and the inner diameters of the second transport section 332 and the third transport section 333 can be the same. In some embodiments, the channel walls of the first diameter-changing portion 3321 and the second diameter-changing portion 3331 are both arc-shaped, and the arc angle can be less than 90°, or the channel walls of the first diameter-changing portion 3321 and the second diameter-changing portion 3331 can both be conical.

[0055] In some embodiments, where the air intake channel 32 surrounds the air outlet channel 33 and the air outlet channel 33 includes a first transmission section 331, please continue to refer to Figures 1 and 3. In the extending direction of the air outlet channel 33, the cross-sectional dimensions of the air intake channel 32 are uniform everywhere. In a plane perpendicular to the extending direction of the air outlet channel 33, the channel wall of the air intake channel 32 and the channel wall of the first transmission section 331 are spaced apart. The channel wall of the air intake channel 32 and the channel wall of the air outlet channel 33 enclose a closed cavity 38. This closed cavity 38 can be formed at the location of the first transmission section 331. On the one hand, this avoids the arrangement of the first transmission section 331 affecting the change in the cross-sectional dimensions of the air intake channel 32. On the other hand, the high-temperature aerosol in the air outlet channel 33 can transfer heat to the closed cavity 38, reducing the temperature of the aerosol in the air outlet channel 33 through the gas in the closed cavity 38. Furthermore, the uniform cross-sectional dimensions of the air intake channel 32 reduce the suction resistance when the user inhales the aerosol, improving the user experience.

[0056] In some embodiments, the channel wall of the air intake channel 32 can be separately disposed from the channel wall of the air outlet channel 33. For example, in some embodiments, the nozzle 3 includes a cylindrical structure, the air intake channel 32 is located in the interlayer space of the cylindrical structure wall, the channel wall of the air outlet channel 33 is hourglass-shaped, and the channel wall of the air outlet channel 33 has a reduced diameter section, which corresponds to the first transmission section 331. The channel wall of the air outlet channel 33 can be connected to the cylindrical structure by means of threaded connection or snap-fit ​​connection to realize the assembly of the entire nozzle 3; or in other embodiments, the cylindrical structure in the nozzle 3 can also be integrally formed with the channel wall of the air outlet channel 33.

[0057] In some embodiments, the air intake channel 32 and the air outlet channel 33 share a channel wall. Since the air outlet channel 33 has a first transmission section 331 with a small cross-sectional area, the air intake channel 32 has a portion with a large cross-sectional area. This portion corresponds to the first transmission section 331 in the extension direction of the air outlet channel 33. In this way, the air intake channel 32 forms a structure in the air intake direction where the cross-sectional area gradually increases and then decreases again. This helps to increase the air intake volume of the air intake channel 32, reduce the aerosol concentration, and meet user needs.

[0058] In some embodiments, referring to Figures 1 and 3, the exhaust channel 33 has a collection cavity 3322 for collecting aerosols. The collection cavity 3322 is located on the side of the first transmission section 331 opposite to the third transmission section 333. The collection cavity 3322 communicates with the heating cavity 221 when the nozzle 3 is engaged with the heating body 2 to collect aerosols and also to buffer aerosols during the suction gap and suction process. In a plane perpendicular to the extension direction of the exhaust channel 33, the cross-sectional dimension of the collection cavity 3322 is larger than the cross-sectional area of ​​the heating cavity 221. The second transmission section 332 encloses and forms the collection cavity 3322. The cylindrical cavity structure, because the cross-sectional area of ​​the second transmission section 332 is larger than that of the heating cavity 221 in the plane extending perpendicular to the air outlet channel 33, satisfies the condition that the cross-sectional area of ​​the collection cavity 3322 is larger than that of the heating cavity 221 and also larger than that of the first transmission section 331. The aerosol discharged from the heating cavity 221 will have a reduced velocity after entering the collection cavity 3322. This allows for the aerosol to be collected while simultaneously achieving diffusion and cooling through the collection cavity 3322, which helps ensure the continuity of the aerosol and thus improves the user's taste and experience.

[0059] Those skilled in the art will understand that the cross-sectional shape of the outlet channel 33 is circular, and the inner diameter of the first transmission section 331 is smaller than the inner diameter of the collection cavity 3322. Therefore, after the aerosol enters the first transmission section 331 from the collection cavity 3322, the flow velocity increases due to the reduced flow cross-sectional area, according to the continuity equation in fluid mechanics. Simultaneously, according to Bernoulli's principle, the increase in aerosol flow velocity leads to a decrease in the static pressure of the aerosol, which further promotes aerosol acceleration. In other words, a suitable inner diameter ratio between the first transmission section 331 and the collection cavity 3322 facilitates accelerated aerosol transport, enabling the aerosol to reach the required flow rate, such as 120-200 mL / s. Exemplarily, in some embodiments, the inner diameter ratio between the first transmission section 331 and the collection cavity 3322 can be set between 1:8 and 1:4, for example, 1:8, 1:7, 1:6, 1:5, and 1:4. In other embodiments, the ratio of the inner diameters of the first transmission segment 331 and the collection cavity 3322 may also be set to other ratios to meet design and usage requirements.

[0060] Of course, in other embodiments, the air outlet channel 33 may not have a second transmission section 332 or a collection chamber 3322. The heating chamber 221 may be directly connected to the first transmission section 331, and the aerosol may be collected and cooled only through the third transmission section 333 connected to the first transmission section 331.

[0061] In order to further improve the cooling efficiency and cooling effect of aerosols, in some embodiments, please continue to refer to Figures 1 and 3, in the structure in which a collection chamber 3322 is provided in the air outlet channel 33, a side wall air supply port 34 is provided on the cavity wall of the collection chamber 3322, that is, on the side wall of the air passage of the second transmission section 332, or the nozzle 3 and the heating body 2 enclose to form a side wall air supply port 34 that communicates with the collection chamber 3322. The side wall air supply port 34 can communicate with the outside of the nozzle 3 or the external space of the heating non-combustible component. The side wall air supply port 34 is used to allow external airflow to enter into the collection chamber 3322 to mix with the aerosols collected in the collection chamber 3322, thereby increasing the cooling efficiency of the aerosols and improving the cooling effect of the aerosols.

[0062] In some embodiments, the side wall air supply port 34 can be located on the side of the collection chamber 3322 near the heating chamber 221, that is, on the side of the second transmission section 332 near the heating chamber 221, so that the aerosol and external gas continue to mix during the process of passing through the second transmission section 332 and the first transmission section 331, which helps to prolong the mixing time, improve the mixing uniformity, and thus enhance the consistency of the sucking taste.

[0063] In some embodiments, referring to Figures 1 and 3, the air inlet channel 32 is arranged around the air outlet channel 33, and the side wall air supply port 34 is connected to the air inlet channel 32, so that external gas can enter the air inlet channel 32 through the air inlet 312 and then enter the collection chamber 3322 through the side wall air supply port 34. The air inlet 312 is located on the outside of the third transmission section 333. The air inlet 312 and the side wall air supply port 34 are located at both ends of the air inlet channel 32 in the extension direction of the air outlet channel 33, so that the external gas can carry away the heat of the aerosol in the air outlet channel 33 during the air intake process, which helps to improve the cooling effect. The gas flow directions in the air outlet channel 33 and the air inlet channel 32 are opposite, which helps to maintain a large temperature difference between the aerosol in the air outlet channel 33 and the gas in the air inlet channel 32, which helps to improve the heat exchange efficiency and further enhance the cooling effect. In other embodiments, the side wall air supply port 34 may also penetrate the cylindrical wall of the nozzle 3 in the radial direction of the air outlet channel 33, and the side wall air supply port 34 communicates with the external space of the heated non-combustible component through the opening on the first main body 11.

[0064] In some embodiments, referring to Figures 1 and 3, at least two sidewall air inlets 34 are arranged at intervals in the circumferential direction of the second transmission section 332, so that external gas can enter the collection chamber 3322 from multiple directions, which helps to uniformly introduce gas, improve the mixing and cooling effect, and avoid local overheating or local undercooling of aerosol in the collection chamber 3322.

[0065] In some embodiments, referring again to Figures 1 and 3, the sidewall air supply ports 34 are connected to the air inlet channel 32. At least two air inlets 312 are arranged circumferentially around the air outlet channel 33, and the number of air inlets 312 is not less than the number of sidewall air supply ports 34. Those skilled in the art will understand that when multiple air inlets 312 are provided, the number of sidewall air supply ports 34 can be set according to the situation to adjust the ratio of gas to aerosol during suction, which helps to achieve concentration dilution and adjustment of suction resistance and cooling effect. For example, by adjusting the number of sidewall air supply ports 34, the gas flow rate entering through the sidewall air supply ports 34 can account for 10%-50% of the total flow rate of the suctioned aerosol.

[0066] In some embodiments, the sidewall air supply port 34 can be configured such that the airflow velocity through the sidewall air supply port 34 during suction is 17.5 ml / s-30 ml / s, in order to provide the user with a good suction experience. Those skilled in the art will understand that the number of sidewall air supply ports 34 can be adjusted to ensure that the airflow velocity through the sidewall air supply ports 34 during suction is within the desired range; the size and shape of the sidewall air supply ports 34 can also be adjusted to allow the airflow to accelerate or decelerate as needed during its passage through the sidewall air supply ports 34, thereby achieving the desired velocity range. Of course, in other embodiments, the airflow through the sidewall air supply port 34 can also be configured to other velocities.

[0067] In some embodiments, the nozzle 3 has a one-way air intake structure 341 communicating with the collection chamber 3322, or the nozzle 3 and the heating body 2 enclose each other to form a one-way air intake structure 341 communicating with the collection chamber 3322. The one-way air intake structure 341 is used to communicate with the external space of the heated non-combustible component so that the cold airflow from the external space can enter the collection chamber 3322 through the one-way air intake structure 341 and mix with the aerosol.

[0068] Please refer to Figures 1 and 3. In some embodiments, a one-way air intake structure 341 is provided on the air supply channel corresponding to the side wall air supply port 34. The one-way air intake structure 341 is used to allow gas outside the heating non-combustible component to flow into the collection chamber 3322 in one direction, and to restrict the aerosol from being discharged through the side wall air supply port 34 and the air supply channel, thereby reducing aerosol loss.

[0069] In some embodiments, referring to Figures 1 and 3, the air supply duct corresponding to the side wall air supply port 34 may include the side wall air supply port 34, the air intake channel 32, and the air intake port 312. That is, the one-way air intake structure 341 may be located at the side wall air supply port 34, in the air intake channel 32, or at the air intake port 312. In other embodiments, the side wall air supply port 34 is disposed through the cylindrical wall of the nozzle 3. The air supply duct corresponding to the side wall air supply port 34 includes the side wall air supply port 34 and the opening on the first main body 11. The one-way air intake structure 341 may be located at the side wall air supply port 34.

[0070] The location and configuration of the one-way air intake structure 341 are not limited, as long as it allows gas from outside the heated non-combustible component to flow unidirectionally into the collection chamber 3322. For example, the one-way air intake structure 341 includes a Tesla valve disposed in the side wall air supply port 34 to prevent aerosol in the second transmission section 332 from flowing back into the air intake channel 32; or the one-way air intake structure 341 may also be a one-way valve with a valve plate, valve disc, or valve core.

[0071] In some embodiments, the sidewall air supply port 34 can be located on the channel wall at the end where the second transmission section 332 connects with the heating chamber 221. Alternatively, referring to Figures 1 and 3, a portion of the sidewall air supply port 34 can be located on the channel wall of the second transmission section 332, and another portion can be located on the cavity sidewall of the heating chamber 221. The Tesla valve located in the sidewall air supply port 34 can be composed of two valve bodies joined together, with one valve body located in a portion of the sidewall air supply port on the sidewall of the second transmission section 332, and the other valve body located in a portion of the sidewall air supply port on the sidewall of the heating chamber 221.

[0072] Of course, in other embodiments, the side wall air supply port 34 and the one-way air intake structure 341 can be omitted, and all the air entering the air intake channel 32 from the air intake port 312 can be used to supply air to the heating chamber 221. The concentration of aerosol at the outlet of the air outlet channel 33 and the temperature of aerosol can be reduced by setting the volume of the second transmission section 332 and the third transmission section 333 and the air intake volume and intake rate of the air intake port 312.

[0073] In some embodiments, the heated non-combustible assembly includes an assembly body 100 and a suction port 37. The assembly body 100 has an aerosol generation chamber and a suction port. The aerosol generation chamber is used to contain and heat the solid aerosol matrix 4, and the suction port is connected to the aerosol generation chamber. In use, the solid aerosol matrix 4 pre-loaded in the aerosol generation chamber is heated to generate aerosol. By suctioning through the suction port, the aerosol generated in the aerosol generation chamber can be drawn out from the suction port, which is also the outlet of the gas outlet channel 33.

[0074] In some embodiments, referring to Figures 2 and 3, the main body 100 includes a heating body 2 and a suction head 30. The suction head 3 includes a suction head 30 and a suction member 37. The air inlet 312, the air inlet channel 32, and the air outlet channel 33 are all located on the suction head 30. The suction member 37 is detachably mounted on the suction head 30. The suction member 37 is located on the side of the air outlet channel 33 facing away from the heating chamber 221 in the extending direction of the air outlet channel 33.

[0075] The mouthpiece body 30 and the heating body 2 are open to each other and can be connected. The heating body 2 includes a heating chamber 221, and the mouthpiece body 30 includes a cooling chamber. When the mouthpiece body 30 is connected to the heating body 2, the heating chamber 221 and the cooling chamber combine to form an aerosol generation chamber. The heating chamber 221 is used to contain and heat the solid aerosol matrix 4. The separate arrangement of the mouthpiece body 30 and the heating body 2 makes it easy to install the solid aerosol matrix 4 into the heating chamber 221. The cooling chamber, which is also the collection chamber 3322, can buffer and cool the aerosol generated in the heating chamber 221, which helps to reduce the risk of burns when the user sucks in the aerosol and improves the sucking experience.

[0076] In some embodiments, please refer to Figures 2 and 3. The suction port is the outlet of the air outlet channel 33. In order to meet the diverse suction needs and preferences of different users, in some embodiments, an installation part 310 is provided at the outlet of the air outlet channel 33. The installation part 310 allows the suction component 37 to be detachably installed at the outlet of the air outlet channel 33.

[0077] The suction element 37 can be understood as a modular component that can add the necessary additional functions to the heated non-combustible assembly. The mounting part 310 is used to cooperate with the suction element 37 so that the suction element 37 can be installed at the outlet of the air outlet channel 33. Therefore, the mounting part 310 only needs to be used to fix the suction element 37, and the specific form of the mounting part 310 is not limited. In other embodiments, the mounting part 310 can be omitted, and the suction element 37 is also fitted onto the nozzle body 30 and located at the outlet of the air outlet channel 33.

[0078] In some embodiments, the mounting part 310 includes a mounting groove 311 disposed at the outlet of the air outlet channel 33. The mounting groove 311 is an annular groove, and is used for at least a portion of the suction component 37 to be inserted and fixed in the outlet of the air outlet channel 33. The bottom of the mounting groove 311 forms a stepped portion, which can limit the insertion depth of the suction component 37. In other embodiments, the mounting part 310 may also be a snap-fit ​​or a clamp for engaging and fixing the suction component 37. The suction component 37 can be detachably mounted to the mounting part 310 by means of interference fit, snap-fit, or threaded connection.

[0079] To ensure stable installation of the suction-absorbing component 37 while facilitating suction by the lip enveloping the protruding portion 31, in some embodiments (referring to Figures 1 and 3), the inner diameter of the mounting groove 311 for installing the suction-absorbing component 37 can range from 6 to 8 mm. For example, the inner diameter of the mounting groove 311 can be 6 mm, 6.5 mm, 7 mm, 7.5 mm, or 8 mm. In some embodiments, the axial length of the mounting groove 311 can range from 5 to 10 mm. For example, the axial length of the mounting groove 311 can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, or 10 mm. This ensures that the mounting groove 311 provides sufficient installation and fixing space for the suction-absorbing component 37 while also having a suitable length for the lip to hold it. In other embodiments, the inner diameter and axial length of the mounting groove 311 can also adopt other dimensions, as long as they are sufficient for the lip to hold or for the suction-absorbing component 37 to be stably installed.

[0080] In some embodiments, referring to Figures 1 and 3, the suction component 37 may include at least one functional module 372 selected from a filter section, a cooling section, and a flow regulation section. These various functional modules 372 enable the suction component 37, after being installed at the outlet of the exhaust channel 33, to perform additional functions such as filtration, cooling, and flow regulation to meet diverse suction needs of users.

[0081] In a further embodiment, referring to Figures 1 and 3, functional module 372 is a filter section, in which a fragrance carrier 373 is disposed, so that the adsorption member 37 containing the filter section can not only filter the aerosol, but also impart additional flavor to the aerosol. Exemplarily, the filter section can be filter cotton, and the fragrance carrier 373 can be a bursting bead. The bursting bead can be filled in the filter cotton. During use, by squeezing the filter cotton from the outside, the bursting bead breaks, and the fragrance in the bursting bead diffuses into the filter cotton. When the aerosol passes through the filter cotton, it can carry the fragrance or its volatile components and be drawn out.

[0082] Those skilled in the art will understand that the structures of various functional modules 372 may differ. Therefore, depending on the structure of the functional module 372, some functional modules 372 can directly cooperate with the mounting part 310 to be fixed at the suction port; others require the assistance of other accessories that can cooperate with the mounting part 310 to be fixed at the suction port. In some embodiments, referring to Figures 1 and 3, the suction component 37 also includes an accessory housing 371, which is detachably installed in the mounting part 310. The functional module 372 is disposed in the accessory housing 371, and the accessory housing 371 is installed at the suction port by a snap-fit, threaded connection, or interference fit.

[0083] In some embodiments, referring to Figures 1 and 3, the suction nozzle 3 has a first portion 35 and a second portion 36 arranged in the extending direction of the air outlet channel 33. The air outlet channel 33 connects the first portion 35 and the second portion 36. The inlet of the air outlet channel 33 is located on the first portion 35, and the outlet of the air outlet channel 33 is located on the second portion 36. The heating body 2 includes a heating cylinder 22 that surrounds and forms a heating cavity 221. The first portion 35 and the second portion 36 are arranged in the extending direction of the air outlet channel 33. The first portion 35 can fit against the heating cylinder 22, and the second portion 36 is connected to the side of the first portion 35 away from the heating cylinder 22, so that the second portion 36 and the heating cylinder 22 are spaced apart. The heat deformation temperature of the first portion 35 is higher than that of the second portion 36, which can reduce the cost of the suction nozzle 3 and the entire heating and non-combustible assembly while ensuring that the suction nozzle 3 has good temperature resistance.

[0084] The first part 35 and the second part 36 can be detachably connected or integrally formed. In some embodiments, the first part 35 and the second part 36 can be separately set at the bottom wall of the mounting groove 311. The second part 36 is a cylindrical structure with open ends. The first part 35 and the second part 36 can be detachably connected by threads or snaps. The air inlet 312 and the air inlet channel 32 are both located on the first part 35. The second part 36 is used to be set on the outside of the appliance body 1 in the heated non-combustible appliance for the user's lips to cover. In some embodiments, the first part 35 and the second part 36 can also be integrally formed.

[0085] In some embodiments, the heat distortion temperature of the first portion 35 is greater than 200°C, and the heat distortion temperature of the second portion 36 is less than that of the first portion 35. The material of the first portion 35 can be Teflon, PEEK (Polyetheretherketone), or PI (Polyimide). In some embodiments, the material of the second portion 36 can be silicone, PEI (Polyetherimide), PCTG (Polyethylene Terephthalate Glycol), PC (Polycarbonate), or POM (Polyformaldehyde).

[0086] In other embodiments, the first part 35 and the second part 36 may also be separately configured at the second transmission segment 332, the first transmission segment 331, or the third transmission segment 333.

[0087] Of course, in other embodiments, in order to facilitate processing and manufacturing, the structure that encloses the air inlet channel 32 and the air outlet channel 33 in the nozzle 3 can be set as an integral molding structure, and the overall heat deformation temperature of the nozzle 3 is greater than 200°C, so as to ensure that the nozzle 3 has a long service life.

[0088] In some embodiments, referring to Figures 1 and 3, the nozzle 3 has a circular outer contour in a cross section perpendicular to its extension direction, and the outer peripheral surface of the nozzle 3 is cylindrical. The air inlet 312 is located on the outer peripheral surface of the nozzle 3. The air inlet channel 32 is arranged around the air outlet channel 33. There are multiple air inlets 312, which are spaced apart in the circumferential direction around the air outlet channel 33. This helps to achieve uniform air intake in the heating chamber 221 in the circumferential direction around the air outlet channel 33.

[0089] In one embodiment, the air intake channel 32 is arranged around the air outlet channel 33. In the air intake direction of the air intake airflow, the first part 35 is provided with a plurality of air outlets 321 downstream of the air intake channel 32. Two adjacent air outlets 321 are arranged at intervals in the circumferential direction around the air outlet channel 33. The air outlets 321 are used to communicate with the heating chamber 221 through the gas inlet 231 of the heating body 2 when the nozzle 3 is sealed and joined with the heating body 2, so as to ensure uniform air intake in the heating chamber 221.

[0090] Of course, in other embodiments, the air intake channel 32 and the air outlet channel 33 can also be arranged side by side in a plane perpendicular to the extension direction of the air intake channel 32.

[0091] In some embodiments, referring to FIG1, the exhaust channel 33 has a narrowed section on the first portion 35, namely the first transmission section 331. This narrowed section helps to increase the aerosol discharge rate and prevent aerosol condensation. The portions of the exhaust channel 33 with a larger cross-sectional dimension than the narrowed section, namely the second transmission section 332 and the third transmission section 333, can collect and buffer aerosols to increase the aerosol concentration and improve user satisfaction. The entire nozzle 3, the air outlet channel 33, and the air inlet channel 32 extend in the same direction. In the direction of the air outlet channel 33, the channel wall of the air inlet channel 32 and the channel wall of the air outlet channel 33 enclose each other at the narrowing section to form a closed cavity 38. The cross-sectional dimensions of the air inlet channel 32 are equal everywhere in the direction perpendicular to its extension. This can avoid the increase in suction resistance caused by the narrowing section. The air inlet channel 32 with equal cross-sectional dimensions everywhere helps to reduce suction resistance and improve the user experience. In addition, the closed cavity 38 formed by the channel wall of the air inlet channel 32 and the channel wall of the air outlet channel 33 can cool down the aerosol in the air outlet channel 33 to avoid the aerosol burning the nozzle.

[0092] Of course, in other embodiments, the intake channel 32 and the exhaust channel 33 can share the same channel wall at the narrowing section, and the cross-sectional size of the intake channel 32 is the same everywhere, which also helps to reduce suction resistance and improve user experience.

[0093] In other embodiments, the intake channel 32 and the outlet channel 33 share a channel wall at the narrowing section. The cross-sectional size of the intake channel 32 gradually increases and then gradually decreases from the intake port 312 to the outlet port 321. This can increase the intake volume of the intake channel 32 and meet the intake requirements.

[0094] In some embodiments, please refer to Figures 1 and 3. For the heating body 2, the heating body 2 has a gas inlet 231, a gas guide channel 23 and a gas outlet 232. The gas inlet 231 and the gas outlet 232 are located at both ends of the gas guide channel 23. The gas inlet 231 can connect the gas inlet channel 32 and the gas guide channel 23 when the nozzle 3 is combined with the heating body 2.

[0095] In some embodiments, please refer to Figures 1 and 3. The heating body 2 includes a heating cup 20. An air guide channel 23 is provided in the peripheral wall of the heating cup 20. When the nozzle 3 is connected to the heating body 2, the air guide channel 23 is connected to the air inlet channel 32. The heating cup 20 includes a gas outlet 232. The gas outlet 232 is located on the side of the heating cup 20 away from the nozzle and is connected to the heating chamber 221 to supply gas to the heating chamber 221.

[0096] In some embodiments, the heating body 2 includes a honeycomb heating component 24 located inside the heating cup body 20. A gas guide channel 23 is arranged around the honeycomb heating component 24. The gas guide channel 23 is connected to the gas passage of the honeycomb heating component 24 through its gas outlet 232. The gas passage of the honeycomb heating component 24 is also connected to the heating chamber 221.

[0097] In some embodiments, referring to Figures 1 and 3, the heating cup body 20 includes a heating cylinder 22 and a mounting cylinder 21. The extending directions of both the mounting cylinder 21 and the heating cylinder 22 are consistent with the extending direction of the air outlet channel 33. The mounting cylinder 21 is open at one end and closed at the other end in its extending direction. The heating cylinder 22 is a cylindrical structure with open ends. The heating cylinder 22 is located inside the mounting cylinder 21 and can be supported and installed at the closed end of the mounting cylinder 21. The heating cylinder 22 can be connected to the second main body part 12 of the appliance body 1 through the mounting cylinder 21. The second main body part 12 of the appliance body 1 includes a second housing. The mounting cylinder 21 can be connected to the second housing by threaded connection, snap-fit ​​connection or interference fit. The closed end of the mounting cylinder 21 is suspended in the second housing. The mounting cylinder 21 is spaced apart from the circuit board, battery cell and other components in the second housing to reduce the heat transferred from the heating cup body 20 to other components in the second housing.

[0098] The sidewall of the heating cylinder 22 is spaced apart from the sidewall of the mounting cylinder 21 to form a gas guiding channel 23 between the heating cylinder 22 and the mounting cylinder 21. That is, the heating cup body 20 has a gas inlet 231 and a gas guiding channel 23 communicating with the gas inlet 231. The heating chamber 221 is located inside the heating cylinder 22. A honeycomb heating component 24 is also provided inside the heating cylinder 22. The honeycomb heating component 24 has several heat exchange channels communicating with the internal space of the mounting cylinder 21 and the heating chamber 221.

[0099] The air guide channel 23 is arranged around the honeycomb heating component 24. The heat exchange air passage of the honeycomb heating component 24 connects the air guide channel 23 and the heating chamber 221. The gas inlet 231 of the air guide channel 23 can be formed on the top end face of the heating cup body 20. Correspondingly, the air outlet 321 of the air inlet channel 32 can be formed on the bottom end face of the nozzle 3. There are at least two air outlets 321 of the air inlet channel 32 and at least two gas inlets 231 of the air guide channel 23. The air outlets 321 of the multiple air inlet channels 32 are arranged circumferentially around the air outlet channel 33 and at intervals. The gas inlets of the multiple air guide channels 23 are also arranged at intervals. The gas inlets 231 are spaced circumferentially around the heating chamber 221. The number of gas outlets 321 in the inlet channel 32 is not less than the number of gas inlets 231 in the guide channel 23. At least some of the gas outlets 321 in the inlet channel 32 correspond one-to-one with the gas inlets 231 in the guide channel 23. In this way, the guide channel 23 can connect with the inlet channel 32 when the nozzle 3 is engaged with the heating body 2. The airflow entering the inlet channel 32 from the inlet 312 can enter the mounting cylinder 21 along the guide channel 23, and then enter the heat exchange air passage from the closed end of the mounting cylinder 21. It is understood that in some embodiments, the gas inlets 231 of the guide channel 23 and the gas outlets 321 of the inlet channel 32 have the same shape and size.

[0100] In some embodiments, please refer to Figures 1 and 3. The air intake channel 32 is also connected to the collection chamber 3322 through the side wall air supply port 34. The side wall air supply port 34 has a one-way air intake structure 341. After the external air enters the air intake channel 32, part of it enters the second transmission section 332 through the one-way air intake structure 341, and the other part enters the honeycomb heating component 24 through the air guide channel 23.

[0101] The honeycomb heating assembly 24 includes a honeycomb heat exchanger 241 and a heating element 242. The honeycomb heat exchanger 241 has a cylindrical structure, and the heat exchange air passage is located on the honeycomb heat exchanger 241. The heating element 242 is fixed on the inner wall of the heating cylinder 22 or on the outer wall of the honeycomb heat exchanger 241. The heat of the heating element 242 can be transferred to the honeycomb heat exchanger 241, which can heat the airflow flowing through the heat exchange air passage to form a hot airflow. The hot airflow enters the heating chamber 221 from the heat exchange air passage to heat the solid aerosol matrix 4 to generate aerosol. The heat of the heating element can also be transferred to the airflow in the air guide channel 23 through the heating cylinder 22 to preheat the intake airflow, which helps to improve the heat utilization rate of the heating body 2 and reduce heat loss.
