[0055] In order to have a clearer understanding of the technical features, purposes and effects of this application, the specific implementation methods of this application are now described in detail with reference to the accompanying drawings.

[0056] As shown in Figures 1 and 2, the non-combustion smoke generating product in some embodiments of the present application includes a fragrance-generating segment 1, a hollow segment 2, a mouthpiece segment 3 and a shell 4. The shell 4 wraps the fragrance-generating segment 1, the hollow segment 2 and the mouthpiece segment 3 therein. The fragrance-generating segment 1, the hollow segment 2 and the mouthpiece segment 3 are arranged in sequence along the axial direction of the shell 4 and are fluidically connected. That is, the hollow segment 2 is located on the side of the proximal lip end of the fragrance-generating segment 1 and is fluidically connected to the fragrance-generating segment 1; the mouthpiece segment 3 is located on the side of the proximal lip end of the hollow segment 2 and is fluidically connected to the hollow segment 2. Moreover, the mouthpiece segment 3 and the hollow segment 2 are connected along the axial direction of the shell 4. It should be noted that the fluid can be a gas, an aerosol or a mixture of a gas and an aerosol, etc. The fluid connection between the fragrance-generating segment 1, the hollow segment 2 and the mouthpiece segment 3 means that the fluid can flow between the fragrance-generating segment 1, the hollow segment 2 and the mouthpiece segment 3. The subsequent description of "fluid connection" can refer to the explanation here. The housing 4 has a certain length. The axial direction of the housing 4 can also be understood as its length direction or the longitudinal direction when in use. The direction perpendicular to the axial direction of the housing 4 or at an angle to the axial center axis of the housing 4 is the radial direction. The fragrance generating section 1, hollow section 2, mouthpiece section 3 and housing 4 can all be cylindrical, but are not limited to cylindrical shapes. They can also be square columns or other regular or irregular shapes.

[0057] The aroma-generating section 1 is primarily used to release aerosols, smoke, etc. for inhalation by the user in a heated state. The mouthpiece section 3 is located closer to the mouthpiece end of the non-combustion smoke-generating product than the aroma-generating section 1. Aerosols, smoke, etc. released from the aroma-generating section 1 flow through the hollow section 2 and the mouthpiece section 3 in sequence for cooling and filtration, before flowing out from the proximal lip end of the mouthpiece section 3 for inhalation by the user. The material of the aroma-generating section 1 may include one or more of aromatic plant fibers and tobacco plant fibers, and may also include spices, adhesives, polyols, and the like.

[0058] In some embodiments, the shell 4 includes a breathable portion through which air can pass. In some embodiments, an air inlet channel 20 is formed at at least one of the three positions, namely, "the proximal lip end of the fragrance-producing segment 1", "the distal lip end of the hollow segment 2", and "between the fragrance-producing segment 1 and the hollow segment 2". That is, the fragrance-producing segment 1 and / or the hollow segment 2 define an air inlet channel 20. The air inlet channel 20 is opposite to and connected to the breathable portion, so that the breathable portion and the interior of the hollow segment 2 can be connected through the air inlet channel 20, so that the interior of the hollow segment 2 is connected to the outside atmosphere.

[0059] Please refer to Figures 1 to 6, wherein Figures 1 to 3 show the first embodiment, and Figures 4 and 6 show the second embodiment and the third embodiment respectively. The common point of the first embodiment, the second embodiment and the third embodiment is that the end faces of the fragrance producing section 1 and the hollow section 2 facing each other are at least partially not in contact, so as to form a radially extending air inlet channel 20 between the positions where the end faces do not contact each other. The air inlet channel 20 is connected to the outside atmosphere through the air permeable section 40. Thus, the outside air enters the air inlet channel 20 from the air permeable section 40, and after mixing with the aerosol generated at the fragrance producing section 1, it flows to the hollow section 2 and the mouthpiece section 3 in sequence for the user to inhale. The air entering from the air permeable section 40 and the air inlet channel 20 can dilute and cool the aerosol generated at the fragrance producing section 1, and at the same time is conducive to the flow of the aerosol and reduces the inhalation resistance.

[0060] Alternatively, please refer to Figure 8, which shows a fourth embodiment. Unlike the first to third embodiments, the aroma-producing section 1 and the hollow section 2 are connected along the axial end faces of the shell 4, that is, there is no gap between the aroma-producing section 1 and the hollow section 2 along the axial direction of the shell 4 (at least there is no gap when observed with the naked eye). Correspondingly, the hollow section 2 is made of breathable material at least in the portion corresponding to the breathable section 40 of the shell 4, so that the breathable section 40 of the shell 4 is connected to the interior of the hollow section 2. As a result, the outside air enters the interior of the hollow section 2 from the breathable section 40, and after mixing with the aerosol generated at the aroma-producing section 1, it flows to the near-lip end of the mouthpiece section 3 for the user to inhale. Similarly, the air entering from the breathable section 40 and the interior of the hollow section 2 can dilute and cool the aerosol generated at the aroma-producing section 1, and at the same time is beneficial to the flow of the aerosol and reduces the inhalation resistance. Specifically, the hollow section 2 made of breathable material has breathable micropores, which may be holes that cannot be observed by the naked eye. The breathable micropores are naturally formed during the manufacturing process of the hollow section 2.

[0061] If the air intake channel 20 of the through-hole structure is opened on the side wall of the hollow section 2, during the production process of the non-combustion smoke generating product, a corresponding punching step needs to be added for each hollow section 2 produced, making the production process of the non-combustion smoke generating product more complicated and limiting the production efficiency. Correspondingly, the present application realizes the air intake of the non-combustion smoke generating product through the air permeable section 40 on the shell 4 and the air intake channel 20 defined by the fragrance generating section 1 and / or the hollow section 2. The air permeable section 40 and the air intake channel 20 are respectively formed during the molding process of the shell 4, the fragrance generating section 1 and / or the hollow section 2, thereby eliminating the step of punching holes in the hollow sections 2 one by one after the molding of each component, simplifying the production process of the non-combustion smoke generating product and improving the production efficiency of the non-combustion smoke generating product.

[0062] As shown in Figures 1 to 3, in the first embodiment, the fragrance-producing segment 1 and the hollow segment 2 are arranged with their end faces facing each other, that is, the adjacent end faces of the fragrance-producing segment 1 and the hollow segment 2 are completely not in contact, but are separated from each other, and the gap between the fragrance-producing segment 1 and the hollow segment 2 forms at least part of the air inlet channel 20.

[0063] In other embodiments, at least one of the two positions of the end surface of the proximal lip end of the fragrance-generating segment 1 and the end surface of the distal lip end of the hollow segment 2 is recessed with an air inlet groove 21 extending in the radial direction of the non-combustion smoke-generating article. The air inlet groove 21 forms at least a portion of the air inlet channel 20. Specifically:

[0064] As shown in Figures 4 and 5, in the second embodiment, unlike the first embodiment, the adjacent end faces of the fragrance-producing segment 1 and the hollow segment 2 are partially in contact and partially not in contact. Specifically, the fragrance-producing segment 1 and the hollow segment 2 are connected along the axial direction of the shell 4, and the end face of the proximal lip end of the fragrance-producing segment 1 is recessed with at least one radially extending air inlet groove 21, and the air inlet groove 21 and the end face of the hollow segment 2 together define an air inlet channel 20. The position where the air inlet groove 21 is located is also the position where the fragrance-producing segment 1 and the hollow segment 2 are not in contact with each other, thereby forming the air inlet channel 20 at this position. Specifically, during the molding process of the solid-state fragrance-producing segment 1, the raw material enters the mold and is extruded to form a solid-state fragrance-producing segment 1 with a relatively stable shape. Therefore, a shape matching the air inlet groove 21 can be reserved on the mold, and the fragrance-producing segment 1 with the air inlet groove 21 on the end face can be formed during the extrusion process, thereby eliminating the process step of punching holes one by one on the hollow segment 2.

[0065] As shown in FIG6 , in the third embodiment, unlike the second embodiment, the air inlet groove 21 is not formed on the fragrance-producing segment 1, but is formed on the hollow segment 2. Specifically, at least one radially extending air inlet groove 21 is formed on the end surface of the distal lip of the hollow segment 2. The air inlet groove 21 and the end surface of the fragrance-producing segment 1 together define an air inlet channel 20. For example, as shown in FIG7 , a through hole extending radially along opposite sides of the outer circumference of a cylinder can be provided, and then the cylinder can be cut into two halves at the middle position of the through hole to obtain two identical hollow segments 2.

[0066] In addition, at least one radially extending air inlet groove 21 can be recessed on the proximal lip end face of the fragrance-producing segment 1 and the distal lip end face of the hollow segment 2, respectively. The air inlet groove 21 on the fragrance-producing segment 1 and the air inlet groove 21 on the hollow segment 2 together define an air inlet channel 20.

[0067] In some embodiments as shown in Figure 1, the length direction of the air inlet channel 20 is perpendicular to the central axis of the fragrance producing segment 1. The length direction of the air inlet channel 20 refers to the central axis of the air inlet channel 20 in the extension direction. However, in other embodiments, as shown in Figure 8, the length direction of the air inlet channel 20 may not be perpendicular to the central axis of the fragrance producing segment 1, but may form an acute angle with the central axis of the fragrance producing segment 1, that is, it may form an angle greater than 0° and less than 90° with the central axis of the fragrance producing segment 1. In other embodiments, the end face of the proximal lip end of the fragrance producing segment 1 is inclined in the direction away from the hollow segment 2, so that the end face of the proximal lip end of the fragrance producing segment 1 forms an acute angle with its central axis, which is equivalent to the length direction of the air inlet channel 20 forming an acute angle with the central axis of the fragrance producing segment 1. As a result, an inclined air inlet channel 20 is formed between the end face of the proximal lip end of the fragrance producing segment 1 and the end face of the distal lip end of the hollow segment 2.

[0068] As shown in FIG8 , in the fourth embodiment, the difference between the first to third embodiments is that the proximal lip end face of the fragrance-producing segment 1 and the distal lip end face of the hollow segment 2 are connected along the axial end face of the shell 4. That is, along the axial direction of the shell 4, there is no gap between the proximal lip end face of the fragrance-producing segment 1 and the distal lip end face of the hollow segment 2. In this case, the hollow segment 2 is made of a breathable material at least in the portion corresponding to the breathable section 40 of the shell 4, so that the breathable section 40 of the shell 4 is connected to the interior of the hollow segment 2. The hollow segment 2 can be made of a breathable fiber material, such as cellulose acetate, which has breathable micropores that are interconnected.

[0069] The aroma-producing segment 1 may also have breathable micropores, which are formed by drying the moisture from the raw materials during the molding process of the aroma-producing segment 1. The pore size of the breathable micropores in the aroma-producing segment 1 is positively correlated with the particle size of the aerosol. Preferably, the porosity of the breathable micropores in the aroma-producing segment 1 may be 20% to 80%. The pore size of the aroma-producing segment 1 may be 50 nm to 20 μm. After the aroma-producing segment 1 is heated, the aerosol generated by the heating can be released through the micropores, allowing the aerosols generated at different locations to mix, making the aerosol more uniform, and then flow to the hollow segment 2. The hollow segment 2 can serve as a centralized storage and cooling function for the aerosol. When the user inhales, they will first inhale the aerosol in the hollow segment 2. After the aerosol in the hollow segment 2 is sucked away, the newly generated aerosol will flow back into the hollow segment 2, which can effectively prevent the aerosol from flowing directly into the user's mouth, avoid burning the mouth, and improve the taste of the aerosol. The ventilation micropores on the hollow section 2 can be set with reference to the ventilation micropores of the fragrance-producing section 1, and will not be repeated here.

[0070] As shown in Figures 9 to 12, in one or more embodiments, the cross-sectional profile of the air inlet groove 21 (also referred to as the air inlet channel 20 in the figures) on the aroma producing section 1 can be a curve, a broken line, or a combination of curves and broken lines. It should be noted that "cross-sectional" and "longitudinal section" are merely relative terms relative to the air inlet groove 21 itself. The direction in which the air inlet groove 21 extends, i.e., the radial direction, is the longitudinal direction of the air inlet groove 21, and a cross section of the air inlet groove 21 in its longitudinal direction is referred to as its longitudinal section. Correspondingly, the direction perpendicular to the longitudinal direction of the air inlet groove 21 is the transverse direction of the air inlet groove 21. Therefore, the cross-sectional profile of the air inlet groove 21 refers to a cross section of the air inlet groove 21 in the axial direction of the aroma producing section 1. As shown in Figures 4, 6, and 9, in some embodiments, the cross-sectional profile of the air inlet groove 21 is an arc with one curved edge. As shown in Figure 10, in other embodiments, the cross-sectional profile of the air inlet groove 21 is a rectangle with three straight edges. In some other embodiments, as shown in FIG11 , the cross-sectional profile of the air inlet groove 21 is V-shaped with two straight edges. In some other embodiments, as shown in FIG12 , the cross-sectional profile of the air inlet groove 21 is polygonal with eight straight edges. Of course, the cross-sectional profile of the air inlet groove 21 may also have other regular or irregular shapes. Of course, the air inlet groove 21 in the third embodiment may also be configured similarly to the shape of the air inlet groove 21 in the second embodiment. The ventilation structure on the housing 4 may be a vent 401, which is a hole visible to the naked eye. For example, as shown in FIG13 and FIG14 , in some embodiments, the ventilation portion on the housing 4 is at least one vent 401 that is in one-to-one communication with at least one air inlet groove 21. Specifically, the vent 401 may be pre-formed during the molding process of the housing 4. When the air inlet channel 20 is defined by the air inlet groove 21, there is at least one air inlet groove 21 and at least one vent 401. When there are multiple (meaning at least two) air inlet grooves 21 and air vents 401, the multiple air inlet grooves 21 are distributed along the circumferential direction of the fragrance-producing section 1 on the proximal lip end of the fragrance-producing section 1, or the multiple air inlet grooves 21 are distributed along the circumferential direction of the hollow section 2 on the distal lip end of the hollow section 2, and the multiple air vents 401 are distributed along the circumferential direction of the shell 4 on the shell 4. Each air inlet groove 21 and each air vent 401 are connected in a one-to-one correspondence. Furthermore, when multiple air inlet grooves 21 or air vents 401 are provided, the multiple air inlet grooves 21 can be symmetrically distributed on the fragrance-producing section 1 or the hollow section 2; similarly, the air vents 401 can also be symmetrically distributed on the packaging 4.

[0071] In the embodiments shown in Figures 1 to 4, the breathable portion on the shell 4 can be a breathable membrane structure, for example, it can be breathable paper, breathable cloth, breathable cotton, or other breathable fiber structures, and the holes in the breathable membrane structure are micropores that are invisible to the naked eye. At this time, the breathable portion includes a breathable section 40 that can allow air to pass through. Furthermore, as shown in Figures 1 and 2, in some embodiments, the shell 4 may also include two airtight sections 41 respectively connected to the axial ends of the breathable section 40. One of the airtight sections 41 at least wraps the hollow section 2. The other airtight section 41 at least wraps the fragrance-producing section 1. That is, one of the airtight sections 41 can only wrap the hollow section 2, or can wrap the hollow section 2 and the mouthpiece section 3 at the same time; the other airtight section 41 can only wrap the fragrance-producing section 1, but in other embodiments, a sealing member can be connected to the end face of the distal lip end of the fragrance-producing section 1, and the sealing member is used to prevent aerosol and condensate from overflowing from the bottom. At this time, the other airtight section 41 can simultaneously wrap the fragrance-producing section 1 and the sealing member. The airtight section 41 of the shell 4 makes the interior of the shell 4 have a certain degree of sealing, reducing the aerosol from overflowing outward. The breathable section 40 is used to realize the air intake inside the shell 4, so as to facilitate the flow of aerosol and reduce the inhalation resistance. By reasonably setting the length, material, air permeability and other parameters of the breathable section 40 and the airtight section 41, the inhalation resistance of the non-combustion smoke generating product can be adjusted to a suitable value.

[0072] Furthermore, as shown in Figures 1 and 2, in some embodiments, the airtight section 41 and the breathable section 40 of the shell 4 are split structures, and the two airtight sections 41 are axially connected to the breathable section 40 respectively. That is, the airtight section 41 and the breathable section 40 are two separately formed components, which are connected together by bonding or the like. Moreover, as shown in the embodiments shown in Figures 1 and 2, the two airtight sections 41 are located in the inner layer, and the breathable section 40 is coated on the outer layer of the two airtight sections 41. The outer layer is radially further away from the fragrance-producing section 1 or the hollow section 2 relative to the inner layer. Thus, one of the airtight sections 41 can be used to wrap the filter section and the hollow section 2 together, and the other airtight section 41 can be used to wrap the fragrance-producing section 1, and then the breathable section 40 can be attached between the two airtight sections 41 to form a complete non-combustion smoke-generating product, and the manufacturing process is relatively simple.

[0073] Of course, in some other embodiments, the air permeable section 40 may also be provided in the inner layer. For example, as shown in FIG15 , in the seventh embodiment, the air permeable section 40 of the housing 4 is located in the inner layer, while the two airtight sections 41 are wrapped around the outer layer of the air permeable section 40. Furthermore, in some other embodiments, the airtight section 41 and the air permeable section 40 may also be an integrally formed structure.

[0074] The fragrance-producing segment 1 includes a first segment and a second segment, and the hollow segment 2 also includes a first segment and a second segment. The first segment and the second segment of the fragrance-producing segment 1 are connected along their respective axial directions and are equal in length, and the first segment and the second segment of the hollow segment 2 are connected along their respective axial directions and are equal in length. The end face of the first segment of the fragrance-producing segment 1 is its proximal lip end face, and the end face of the second segment of the hollow segment 2 is its distal lip end face. An air inlet channel 20 is formed between the end face of the first segment of the fragrance-producing segment 1 and the end face of the second segment of the hollow segment 2 (refer to the first to third embodiments). Alternatively, the end face of the first segment of the fragrance-producing segment 1 and the end face of the second segment of the hollow segment 2 are connected end to end (refer to the fourth embodiment).

[0075] As shown in Figures 1 and 2, further, in some embodiments, one end of one of the airtight sections 41 is connected to the airtight section 40 and connected to the side wall of the first section of the fragrance-producing section 1, and the other end of the airtight section 41 is connected to the airtight section 40 and connected to the side wall of the second section of the hollow section 2. The airtight section 40 is connected to the side wall of the first section of the fragrance-producing section 1 and the side wall of the second section of the hollow section 2 at the same time. Of course, in other embodiments, the airtight section 40 can also be connected only to the side wall of the fragrance-producing section 1, and the fragrance-producing section 1 is a fibrous porous body to achieve air intake; or, the airtight section 40 can also be connected only to the side wall of the hollow section 2, and the hollow section 2 is a fibrous porous body to achieve air intake.

[0076] As shown in Figures 1 to 3, in some embodiments, the fragrance-producing segment 1 also includes a first air vent 11 that passes through the end face of the proximal lip end and the end face of the distal lip end, and the air inlet channel 20 is connected to the first air vent 11 and the air permeable segment 40 on the shell 4, respectively. The first air vent 11 is used for collecting and transporting aerosols. Thus, the outside air enters the air vent 401 on the shell 4, the air inlet channel 20 on the fragrance-producing segment 1, and the first air vent 11; during the heating process of the fragrance-producing segment 1, the aerosol released from the fragrance-producing segment 1 is collected at the first air vent 11, and after mixing with the air flowing in from the air inlet channel 20, it flows to the hollow segment 2. The air flowing in from the air inlet channel 20 has the effect of diluting and cooling the aerosol, and is also conducive to the concentrated flow of the aerosol and reducing the inhalation resistance.

[0077] As shown in FIG16 , in some embodiments, the radial cross-section of the first air vent 11 is circular. As shown in FIG17A , in another embodiment, the radial cross-section of the first air vent 11 is elliptical. As shown in FIG17B , in another embodiment, the radial cross-section of the first air vent 11 is rectangular. As shown in FIG17C , in another embodiment, the radial cross-section of the first air vent 11 is star-shaped. As shown in FIG17D , in another embodiment, the radial cross-section of the first air vent 11 is petal-shaped. Of course, the first air vent 11 may also be other regular or irregular shapes. Along the axial direction, the radial cross-section shape of the first air vent 11 may be the same everywhere, or may be different everywhere. For example, the radial cross-section of one end of the first air vent 11 is circular, while the radial cross-section of the other end is rectangular.

[0078] Along the axial direction, the radial dimension of the first air vent 11 can be expressed in the following forms: the radial dimension gradually increases along the direction from the distal lip end face to the proximal lip end face of the fragrance producing segment 1; or, the radial dimension gradually decreases along the direction from the distal lip end face to the proximal lip end face of the fragrance producing segment 1; or, the radial dimension gradually decreases from the distal lip end face of the fragrance producing segment 1 to the middle position of the fragrance producing segment 1, and gradually increases from the middle position of the fragrance producing segment 1 to the proximal lip end face of the fragrance producing segment 1, that is, the first air vent 11 is at the position with the smallest radial dimension at the axial middle position of the fragrance producing segment 1, and the radial dimension of the first air vent 11 at the distal lip end face of the fragrance producing segment 1 is larger than and different from its radial dimension at the proximal lip end face of the fragrance producing segment 1, that is, along the axial direction, the radial dimension of the first air vent 11 is expressed as small-minimum-large or large-minimum-small.

[0079] As shown in Figures 1 to 3, in some embodiments, the hollow section 2 is a solid component, having a cylindrical structure with an axially extending cavity. Specifically, the cavity in the hollow section 2 forms a second vent 22 in the hollow section 2. The second vent 22 is connected to the first vent 11. The hollow section 2 can be a hollow structure, meaning that the second vent 22 can be located at the center of the hollow section 2, but the location of the second vent 22 is not limited to the center of the hollow section 2.

[0080] Alternatively, in other embodiments, the hollow section 2 may not be a solid component, but rather a cavity formed by the fragrance-generating section 1 and the mouthpiece section 3. The aerosol released from the fragrance-generating section 1 gradually accumulates at the first vent 11, flows upward, and accumulates in the hollow section 2 (cavity), where it mixes with the air flowing in from the air inlet channel 20 before flowing toward the mouthpiece section 3.

[0081] The hollow section 2 is used to further collect the aerosol, and the aerosol is further diluted and cooled at the second vent 22, so that the aerosol reaches the mouthpiece of the non-combustion smoke-generating product at a suitable temperature. Correspondingly, the radially extending air inlet channel 20 formed between the fragrance-generating section 1 and the hollow section 2 is connected to the second vent 22 of the hollow section 2. As a result, during the heating process of the fragrance-generating section 1, the aerosol released from the fragrance-generating section 1 gradually collects at the first vent 11, mixes with the air flowing in from the air inlet channel 20, and then flows upward to collect at the second vent 22 of the hollow section 2, and then flows to the mouthpiece section 3.

[0082] In one embodiment, the hollow section 2 is a hollow acetate fiber rod. In another embodiment, as shown in FIG18 , the hollow section 2 is a pleated fiber paper wound within the housing 4 . Slits G are formed between adjacent layers of the fiber paper to allow aerosol to pass through. These slits G serve as the first vent 11, allowing aerosol to flow axially through the hollow section 2 .

[0083] The shape of the second vent hole 22 may be configured with reference to the first vent hole 11 and will not be described in detail here.

[0084] Similar to the first vent hole 11, the radial cross-section of the second vent hole 22 can be the same or different along the axial direction. For example, the radial cross-section of one end of the second vent hole 22 is circular, while the radial cross-section of the other end is rectangular.

[0085] Similar to the first air vent 11, along the axial direction, the radial dimension of the second air vent 22 can be expressed in the following forms: the radial dimension gradually increases along the direction from the far lip end face to the near lip end face of the hollow section 2; or, the radial dimension gradually decreases along the direction from the far lip end face to the near lip end face of the hollow section 2; or, the radial dimension gradually decreases from the far lip end face of the hollow section 2 to the middle position of the hollow section 2, and gradually increases from the middle position of the hollow section 2 to the near lip end face of the hollow section 2, that is, the second air vent 22 is at the position with the smallest radial dimension at the axial middle position of the hollow section 2, and the radial dimension of the second air vent 22 at the far lip end face of the hollow section 2 is larger than and different from its radial dimension at the near lip end face of the hollow section 2, that is, along the axial direction, the radial dimension of the second air vent 22 is expressed as small-minimum-large or large-minimum-small.

[0086] After the aroma-producing section 1 is heated, the aerosol generated by the heating can enter the first air vent 11 through the breathable micropores and be collected, so that the aerosols generated at different positions are mixed to make the aerosol more uniform, and then flow from the first air vent 11 to the second air vent 22 of the hollow section 2. The hollow section 2 can play the role of centralized storage and cooling of the aerosol. When the user inhales, the aerosol in the second air vent 22 of the hollow section 2 will be inhaled first. After the aerosol in the second air vent 22 is sucked away, the newly generated aerosol will flow back into the second air vent 22, which can effectively prevent the aerosol from flowing directly into the user's mouth and avoid burning the mouth.

[0087] As shown in FIG19 , in some embodiments, the length direction of the air inlet groove 21 forms an acute angle with the central axis of the hollow section 2. That is, the air inlet groove 21 is inclined toward the proximal lip end of the hollow section 2, and the distal lip end of the hollow section 2 is formed into a concave tapered surface. In some embodiments, the length direction of the air inlet groove 21 may also be non-collinear with the radial direction of the hollow section 2. As shown in FIG20 , which illustrates a schematic end view of the distal lip end of the hollow section 2 in some embodiments, the length direction of the air inlet groove 21 is inclined relative to the radial direction of the hollow section 2 and is not collinear with any diameter of the hollow section 2. When multiple air inlet grooves 21 are inclined in the same circumferential direction relative to the radial direction of the hollow section 2 (e.g., clockwise), the air inlet grooves 21 are arranged in a vortex-like pattern. During inhalation by a user, air entering the hollow section 2 from the outside through each air inlet groove 21 forms a vortex, which can accelerate the cooling of the aerosol and improve the uniformity of mixing between the aerosol and the air.

[0088] For example, the cross-sectional width of the air inlet groove 21 may gradually change or vary in a gradient along a direction close to the central axis of the hollow section 2 , for example, gradually increase or gradually decrease, that is, the air inlet groove 21 generally has a conical structure.

[0089] As shown in Figure 21, an aerosol generating system according to some embodiments of the present application includes the non-combustion aerosol generating product according to any embodiment and a heating device 50. The heating device 50 is used to heat the non-combustion aerosol generating product so that the non-combustion aerosol generating product generates and releases an aerosol at a certain temperature.

[0090] Furthermore, the heating device 50 includes a housing 5, which is formed with a heating groove. The heating groove is compatible with the non-combustion smoke-generating product of any embodiment of the present application and is for the non-combustion smoke-generating product to be inserted therein. The non-combustion smoke-generating product can be removably installed in the heating groove of the heating device 50. The heating device 50 also includes a heating component (not shown) disposed within the housing 5, a power supply component (not shown) mechanically and / or electrically connected to the heating component, etc. When the heating component is powered on, it heats the non-combustion smoke-generating product inserted in the heating groove to generate aerosol, smoke, etc. When the non-combustion smoke-generating product is installed in the heating groove, its bottom surface can be in contact with the bottom surface of the heating groove, or a certain distance can be left between its bottom surface and the bottom surface of the heating groove.

[0091] As shown in Figures 21 to 23, in some embodiments, the top of the ventilation portion is located above the opening of the heating tank, preventing the ventilation section 40 from being blocked by the inner wall surface of the heating tank, allowing the ventilation portion to be at least partially exposed and connected to the outside air. It should be noted that the housing 4 includes a first end away from the fragrance-producing section 1 (refer to the upper end of the housing 4 in Figure 22) and a second end closer to the fragrance-producing section 1 (refer to the lower end of the housing 4 in Figure 22). The top of the ventilation portion refers to the end of the ventilation portion that is relatively farther away from the second end of the housing 4 (i.e., the upper end of the ventilation section 40 in Figure 321, and the upper end of the ventilation hole 401 in Figures 22 and 23); conversely, the bottom end of the ventilation section 40 refers to the end of the ventilation section 40 that is relatively closer to the second end of the housing 4 (i.e., the lower end of the ventilation section 40 in Figure 21, and the lower end of the ventilation hole 401 in Figures 22 and 23).

[0092] When the non-combustion smoke generating product is installed in the heating tank and the end face of its second end is in contact with the bottom surface of the heating tank, the depth of the heating tank is less than the distance between the top of the air-permeable portion and the second end of the shell 4. The depth of the heating tank refers to the axial dimension of the heating tank. Specifically, when the depth of the heating tank is exactly equal to the distance between the top of the air-permeable portion and the second end of the shell 4, after the non-combustion smoke generating product is inserted into the heating tank, the air-permeable portion on the shell 4 is completely blocked by the wall surface of the heating tank, and air intake is difficult at this time. Therefore, the depth of the heating tank needs to be less than the distance between the top of the air-permeable portion and the second end of the shell 4, so that after the non-combustion smoke generating product is inserted into the heating tank, the air-permeable portion on the shell 4 is at least partially exposed above the heating tank, so that air can smoothly enter the air-permeable portion on the shell 4.

[0093] As shown in Figures 21 to 23, in some embodiments, the depth of the heating groove is equal to the distance between the bottom end of the breathable portion and the second end of the shell 4, that is, the bottom end of the breathable section 40 is just flush with the open end face of the heating groove. At this time, the breathable portion of the shell 4 is completely exposed, and air can smoothly enter the breathable portion.
