[0034] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0035] See also Figure 1 The aerosol generating device 100 of the embodiment of the present application includes a main body component 20 and a receiving tube 10. The receiving tube 10 is detachably connected to the main body component 20, so that the receiving tube 10 can be easily removed from the main body component 20 for cleaning. Figure 8 The containing tube 10 is configured to clamp the aerosol generating article 200, the main body component 20 is configured to receive at least a portion of the containing tube 10, and the main body component 20 includes a power supply component, which is used to provide power for the aerosol generating device 100 to heat the aerosol generating article 200 to generate an aerosol.

[0036] For the above-mentioned receiving tube 10, please refer to Figure 2 The accommodating tube 10 has a side wall 11 which is generally cylindrical. After at least a portion of the circumference of the side wall 11 is surrounded, a first cavity 13 for accommodating at least a portion of the aerosol generating product 200 is formed inside the side wall 11. The accommodating tube 10 is also provided with an opening 12 and a base 14 which are arranged opposite to each other. The opening 12 is arranged at the upper end of the accommodating tube 10 and is configured to allow the aerosol generating product 200 to enter the first cavity 13. The base 14 is connected to the lower end of the side wall 11 and is configured to support the bottom of the aerosol generating product 200 in the first cavity 13.

[0037] A window 111 is provided on the side wall 11 of the accommodating tube 10 and is connected to the first cavity 13. The window 111 is configured to pass through the side wall 11 of the accommodating tube 10. After the accommodating tube 10 is separated from the main body assembly 20, a cleaning tool can enter the first cavity 13 from the outside through the window 111 to clean the tobacco oil, soot and other impurities inside the accommodating tube 10. The side wall 11 of the accommodating tube 10 includes an inclined portion 112, the lower end of the inclined portion 112 is connected to the base 14, and the upper end of the inclined portion 112 has an inclined edge 1121 that defines a local boundary of the window 111, and the inclined edge 1121 extends downward at an angle so that a part of the window 111 is inclined relative to a support surface 141 of the base 14, wherein the support surface 141 of the base 14 is a surface that contacts and supports the bottom of the aerosol generating product 200 when the aerosol generating product 200 is inserted into the first cavity 13, or is a plane where multiple contacts that contact and support the bottom of the aerosol generating product 200 when the aerosol generating product 200 is inserted into the first cavity 13 are located, or the plane where the support surface 141 of the base 14 is located is perpendicular to the center axis M1 of the first cavity 13.

[0038] By partially tilting the window 111 relative to the support surface 141 of the base 14 , the area of ​​the window 111 is increased, thereby facilitating the cleaning tool to enter the first cavity 13 for cleaning and facilitating a more thorough cleaning of the inner wall of the accommodating tube 10 and the base 14 .

[0039] For details, please combine Figure 2 and Figure 3 The window 111 includes a first window 1111 and a second window 1112 which are interconnected and arranged in sequence in the longitudinal direction. At least the second window 1112 of the first window 1111 and the second window 1112 is inclined relative to the support surface 141 of the base 14, so that the normal of the second window 1112 is neither parallel to nor perpendicular to the normal of the support surface 141 of the base 14. Compared with the total area of ​​the window 111 when the normal of the entire window 111 is perpendicular to the normal of the support surface 141 of the base 14, when the window 111 has the same longitudinal length and transverse width, the total area of ​​the window when at least the second window 1112 of the window 111 is inclined relative to the support surface 141 of the base 14 is larger, which makes it easier for the cleaning tool to enter the first cavity 13 for cleaning, and helps to clean the inner wall of the accommodating tube 10 and the base 14 more thoroughly.

[0040] It should be noted that the side wall 11 has a certain thickness, the inner side of the inclined edge 1121 is connected to the inner wall of the inclined portion 112, and the outer side of the inclined edge 1121 is connected to the outer wall of the inclined edge 1121. When the thickness of the side wall 11 is large, the inclined edge 1121 can be approximately an inclined surface (such as Figure 2 and Figure 3 As shown in FIG. 1 , the inclined surface may be a plane, an arc surface or a curved surface; when the thickness of the side wall 11 is small, the inclined edge 1121 may be approximately an inclined line. The distance between the inner side and the outer side of the inclined edge 1121 may be greater than or equal to the thickness of the side wall 11. Figure 2 and Figure 3 In the illustrated embodiment, the inclined edge 1121 extends in an inclined circumferential direction and also extends outwardly and inclinedly, so that the distance between the inner side and the outer side of the inclined edge 1121 is greater than the thickness of the side wall 11. In the present application, the specific form of the inclined edge 1121 is not limited.

[0041] In some embodiments, see Figure 7 and Figure 8The side wall 11 of the accommodating tube 10 includes a first portion 116, which extends in the longitudinal direction, with its upper end defining a part of the boundary of the opening 12, and its lower end connected to the base 14. Along the circumference of the side wall 11, the inclined portion 112 is connected to the first portion 116, so that the sum of the angles R2 of the inclined portion 112 and the first portion 116 surrounding the first cavity 13 together is at least 270°, so that after the aerosol generating article 200 enters the first cavity 13, the first portion 116 and the inclined portion 112 jointly surround the aerosol generating article 200 by at least 270°. Specifically, the inclined portion 112 and the base 14 are formed at points P1 and P2, or the inclined portion 112 and the retaining wall 113 mentioned below are formed at points P1 and P2, the line between point P1 and the central axis M1 of the first cavity 13 is the ray M1 P1, and the line between point P2 and the central axis M1 of the first cavity 13 is the ray M1 P2, wherein the angle R2 between the ray M1 P1 and the ray M1 P2 is at least 270°.

[0042] The containing barrel 10 in the aerosol generating device 100 of the embodiment of the present application is provided with a first portion 116 and an inclined portion 112 on the side wall 11. While increasing the area of ​​the window 111, it is also possible to restrict the trajectory of the aerosol generating product 200 entering the first cavity 13, thereby preventing the aerosol generating product 200 from passing through the window 111 and exiting the first cavity 13 during the process of entering the first cavity 13 due to the excessive area of ​​the window 111, causing the aerosol generating product 200 to be relatively tilted longitudinally when being maintained in the containing barrel 10, thereby affecting the heating effect of the aerosol generating product 200 in the aerosol generating device.

[0043] In such Figure 8 In the embodiment shown, the inclined portion 112 extends from the first portion 116 in the circumferential direction, so that the inclined portion 112 is arc-shaped in the circumferential direction of the side wall 11, and the extension of the first portion 116 in the circumferential direction also makes the first portion 116 arc-shaped in the circumferential direction of the side wall 11. The angle of the first portion 116 surrounding the first cavity 13 can be less than or equal to 200°; the angle of the first portion 116 surrounding the first cavity 13 can be about 180°±30°. For details, please refer to Figure 7 In the circumferential direction of the side wall 11, the first portion 116 forms a point Q1 and a point Q2 at the outer edge close to the inclined portion 112, the line between point Q1 and the central axis M1 of the first cavity 13 is the ray M1Q1, the line between point Q2 and the central axis M1 of the first cavity 13 is the ray M1Q2, wherein the angle R3 between the ray M1Q1 and the ray M1Q2 is 180°±30°.

[0044] As an example, see Figure 8The side wall 11 of the accommodating tube 10 further includes a second portion 117, which extends longitudinally, has an upper end defining a portion of the boundary of the opening 12, and a lower end including a suspended edge 1171 (such as a suspended edge 1171) disposed above the second window 1112. Figure 4 As shown), wherein the inclined edge 1121 is inclined relative to the suspended edge 1171. In other words, the second window 1112 is inclined relative to the suspended edge 1171.

[0045] In such Figure 8 In the embodiment shown, the second portion 117 is connected to the first portion 116, and the sum of the angles of the second portion 117 and the first portion 116 surrounding the first cavity 13 is 360°, so that after the aerosol generating article 200 enters the first cavity 13, the first portion 116 and the second portion 117 jointly surround the aerosol generating article 200. Figure 8 In the embodiment shown, the circumferential extension of the suspended edge 1171 makes the suspended edge 1171 arc-shaped in the circumferential direction of the side wall 11. The angle of the suspended edge 1171 surrounding the first cavity 13 can be greater than or equal to 180°; the angle of the suspended edge 1171 surrounding the first cavity 13 can be about 180°±30°.

[0046] As an example, the first window 1111 includes a longitudinal edge 1113 extending in the longitudinal direction and connected to the inclined edge 1121 on the inclined portion 112, and the longitudinal edge 1113 can be vertically connected to the suspended edge 1171. The longitudinal edge 1113 is bent or curved relative to the inclined edge 1121, so that the normal line of the first window 1111 and the normal line of the second window 1112 intersect in space, or the first window 1111 is bent or curved relative to the second window 1112. Figure 8 In the embodiment shown, the shape of the window 111 is substantially V-shaped. Of course, the surface where the first window 1111 is located can be a flat surface or a curved surface; similarly, the surface where the second window 1112 is located can be a flat surface or a curved surface.

[0047] It is understandable that the first part 116, the second part 117, the inclined portion 112 and the base 14 in the above embodiment can be multiple independent parts connected into a whole by any connection method such as bonding, welding, and clamping, or can be directly integrally formed and manufactured, and the above window 111 is obtained by die cutting. The first part 116, the second part 117 and the inclined portion 112 can be an integrally formed cylindrical structure, and the above window 111 is obtained by die cutting.

[0048] In some embodiments, see Figure 2 and Figure 3There are at least two inclined portions 112, and the two inclined portions 112 are arranged opposite to each other in the circumferential direction of the side wall 11, and the inclined edges 1121 of the two inclined portions 112 extend in the circumferential direction of the side wall 11 in a direction approaching each other, so that a part of the window 111, that is, the second window 1112 is roughly a "V"-shaped structure or a "U"-shaped structure inclined relative to the support surface 141 of the base 14.

[0049] In such Figure 8 In the illustrated embodiment, there are two inclined portions 112, which are respectively connected to opposite sides of the first portion 116, and the sum of the angles of the two inclined portions 112 combined to surround the first cavity 13 can be greater than or equal to 150°; the sum of the angles of the two inclined portions 112 combined to surround the first cavity 13 can be approximately 180°±30°.

[0050] In some embodiments, see Figure 3 The first window 1111 has a first width K1, and the first width K1 and the diameter D1 of the first cavity 13 satisfy at least one of the following conditions: (1) 80% ≤ K1 / D1 ≤ 100%; (2) D1-3mm ≤ K1 ≤ D1. By setting the first width K1 of the first window 1111 to be close to the diameter D1 of the first cavity 13, the lateral width of the first window 1111 can be made large enough to facilitate the cleaning tool to enter the first cavity 13 from the window 111. Figure 8 In one example, the boundary of the first window 1111 includes two longitudinal edges 1113 that are arranged opposite to each other and parallel to each other and extend in the longitudinal direction. The first window 1111 has a uniform width. At different longitudinal heights, the width of the first window 1111 is the first width K1. In other examples, the boundary of the first window 1111 includes connecting edges that are arranged opposite to each other and are connected to the suspended edge 1171 at the upper end and the inclined edge 1121 at the lower end. The connecting edges are curved in the longitudinal direction or are inclined relative to the longitudinal direction, so that the width of the first window 1111 is variable. Then, the first width K1 is the average width of the first window 1111 or the median of the width of the first window 1111.

[0051] In some embodiments, see Figure 3 , the second window 1112 has a second width K2, and the second width K2 and the diameter D1 of the first cavity 13 satisfy at least one of the following conditions: (1) 5% ≤ K2 / D1 ≤ 100%; (2) 1 mm ≤ K2 ≤ D1. Since the inclined portion 112 extends along the circumference of the side wall 11, the inclined portion 112 is curved or arc-shaped in the circumferential direction, so the second width K2 can be variable. Figure 3In the illustrated embodiment, there are two inclined portions 112, so that the second window 1112 is roughly "V"-shaped or "U"-shaped. As it moves away from the center of the first cavity 13, the width of the second window 1112 gradually decreases. In this embodiment, the second width K2 is the average width of the second window 1112 or the median of the width of the second window 1112.

[0052] In some embodiments, see Figure 4 The included angle between the inclined edge 1121 of the inclined portion 112 and the plane where the base 14 is located is an obtuse angle R1, and the obtuse angle R1 satisfies: R1 = 125° ± 20°.

[0053] In some embodiments, see Figure 3 and Figure 4 , along the direction from the base 14 of the receiving tube 10 toward the opening 12, the longitudinal length L1 of the window 111 satisfies: 50mm≤L1≤70mm. By setting the longitudinal length of the window 111 to a relatively large size, it is convenient for a cleaning tool to enter the first cavity 13 and clean the interior of the receiving tube 10.

[0054] In some embodiments, see Figure 3 and Figure 4 , along the direction from the opening 12 of the accommodating tube 10 toward the base 14, the longitudinal height L1' of the second window 1112 and the overall longitudinal height L1 of the window 111 satisfy: 0.25≤L1' / L1≤0.5. The longitudinal height of the second window 1112 is set to 1 / 4 to 1 / 2 of the overall width of the window 111, so that the inclined portion 112 has a sufficient height to support the aerosol generating article 200, and the size of the window 111 will not be excessively reduced, which will affect the entry and exit of the cleaning tool.

[0055] In some embodiments, during the extension of the inclined portion 112 along the circumference of the side wall 11 , as the inclined edge 1121 inclines, the longitudinal height of the inclined portion 112 or the longitudinal distance between the inclined edge 1121 and the base 14 gradually decreases.

[0056] In some embodiments, two adjacent inclined portions 112 are spaced apart in the circumferential direction of the side wall 11, so that when the first portion 116 and the two adjacent inclined portions 112 respectively connected to the opposite sides of the first portion 116 are combined, the sum of the angles surrounding the first cavity 13 is less than 360°.

[0057] Based on this, in one example, the base 14 defines at least a portion of the lower end of the second window 1112 .

[0058] Alternatively, in another example, see Figure 3The side wall 11 of the accommodating tube 10 further includes a retaining wall 113 connected to the base 14. Both sides of the retaining wall 113 are respectively connected to two adjacent inclined portions 112, so that the retaining wall 113 defines at least part of the boundary of the lower end of the second window 1112. Please refer to Figure 5 By providing the retaining wall 113 on the base 14, the end of the aerosol generating product 200 inserted in the first cavity 13 close to the base 14 can be stopped by the retaining wall 113, so as to be confined in the first cavity 13, further preventing the aerosol generating product 200 from passing through the window 111. In addition, the retaining wall 113 abuts against the outer wall of the aerosol generating product 200, which can prevent cold air from entering the first cavity 13 from the tip of the "V"-shaped or "U"-shaped second window 1112 close to the base 14, thereby affecting the heating effect of the aerosol generating product 200. In some examples, see Figure 4 , along the direction from the base 14 of the accommodating tube 10 toward the opening 12 , the longitudinal height H1 of the retaining wall 113 satisfies: 0.5 mm≤H1≤1.5 mm.

[0059] In some embodiments, see Figure 6 Along the radial direction of the first cavity 13, the distance between the inclined portion 112 and the central axis M1 of the first cavity 13 increases as the inclined portion 112 gets closer to the retaining wall 113. Figure 6 The multiple distances r1, r2, and r3 between the middle inclined portion 112 and the central axis M1 of the first cavity 13 increase sequentially. Alternatively, the distance r3 between the retaining wall 113 and the central axis M1 of the first cavity 13 is greater than the distance r4 between the side wall 11 in the accommodating tube 10 and the central axis M1 of the first cavity 13, and / or the distance r3 between the retaining wall 113 and the central axis M1 of the first cavity 13 is greater than the distances r1 and r2 between the inclined portion 112 and the central axis M1 of the first cavity 13, that is, r3>r2>r1. Through the above structure, the side of the retaining wall 113 facing the first cavity 13 can be provided with a clearance groove 114, and the clearance groove 114 is connected to the first cavity 13. Please refer to Figure 5Since the outer wall of aerosol generating products 200 such as cigarettes, cigarette cartridges, and tobacco segments is soft and deformable, in order to ensure the insertion stability and enhance the heating effect, the circumferential size of the aerosol generating product 200 is usually equivalent to the radial size of the first cavity 13, and the side wall 11 of the accommodating tube 10 has a window 111 and the inclined portion 112 is inclined. When the aerosol generating product 200 is inserted into the first cavity 13, the inclined portion 112 will abut or squeeze the side wall 11 of the aerosol generating product 200, resulting in a deformed convex portion protruding outward at the end of the aerosol generating product 200. By providing a clearance groove 114 between the retaining wall 113 and the first cavity 13, it can effectively avoid the deformed convex portion abutting against the top of the retaining wall 113, ensuring that the end of the aerosol generating product 200 can abut against the supporting surface 141 of the base 14.

[0060] In the above embodiment, in order to continue to prevent cold air from entering the first cavity 13 from above the baffle wall 113, the side of the baffle wall 113 facing away from the first cavity 13, that is, the outer wall surface of the baffle wall 113 can be abutted and connected with other components of the aerosol generating device 100 that are sleeved on the outside of the accommodating tube 10, wherein the other components can be the retaining member 30 mentioned below and arranged on the outside of the accommodating tube 10.

[0061] In some embodiments, the receiving tube 10 is observed from a perspective perpendicular to the support surface 141 of the base 14. Figure 6 From a perspective, a longitudinally extending protrusion 115 is provided on the inner surface of the side wall 11 of the accommodating cylinder 10, and the protrusion 115 is used to clamp the aerosol generating product 200 inserted in the first cavity 13. The number of protrusions 115 is at least two, and at least two protrusions 115 are arranged in an array on the side wall 11. The difference between the distance r3 between the retaining wall 113 and the central axis M1 of the first cavity 13 and the distance r4 between the protrusion 115 and the central axis M1 of the first cavity 13 is L2, where L2 satisfies: 0.5mm≤L2≤2mm. The difference L2 can be understood as the distance between the retaining wall 113 and the circle formed by taking the position of the central axis M1 of the first cavity 13 as the center and the distance r4 between the protrusion 115 and the central axis M1 of the first cavity 13 as the radius. That is, the difference L2 is the length of the air-avoiding groove 114 along the radial direction of the first cavity 13. The difference L2 is such that when the aerosol-generating article 200 is received in the first cavity 13 and supported by the base 14 , the aerosol-generating article 200 is spaced apart from the retaining wall 113 .

[0062] In some embodiments, see Figure 1The aerosol generating device 100 further includes a retaining member 30 having a second cavity 31, and at least a part of the accommodating tube 10 is disposed in the second cavity 31. It is understandable that the side of the accommodating tube 10 and the inner surface of the retaining member 30 may be directly abutted and connected, or may be spaced apart. Among them, one of the side wall 11 of the accommodating tube 10 and the retaining member 30 has a slide rail 118 extending in the longitudinal direction, and the other has a slider 32, and the slider 32 is slidably connected to the slide rail 118, and the slide rail 118 provides a guiding function for the slider 32, so that the accommodating tube 10 can reciprocate in the longitudinal direction relative to the retaining member 30, which facilitates the assembly or disassembly of the accommodating tube 10 and the retaining member 30.

[0063] See also Figure 8 and Fig. 9 The present application also provides an embodiment of an aerosol generating system 1000, which includes the above-mentioned aerosol generating device 100 and an aerosol generating product 200. Please refer to Fig. 9 The aerosol generating product 200 includes a mouthpiece section 201, a cooling section 202 and a substrate section 203 capable of generating aerosols, which are arranged in sequence longitudinally. The substrate section 203 includes, but is not limited to, tobacco, tobacco leaves, tobacco shreds and other substances that can generate aerosol volatiles when heated. When the aerosol generating product 200 is connected to the aerosol generating device 100, the substrate section 203 and at least part of the cooling section 202 are located in the first cavity 13, and the bottom of the substrate section 203 abuts against the supporting surface 141 of the base 14. The longitudinal length L1 of the window 111 on the side wall 11 of the accommodating tube 10 is greater than or equal to the longitudinal length L3 of the substrate section 203.

[0064] In some embodiments, see Fig. 9 , along the longitudinal direction of the accommodating tube 10, the distance d1 between the suspended edge 1171 of the first window 1111 and the opening 12 is less than or equal to the distance d2 between the upper end of the matrix segment 203 and the opening 12, wherein the difference between d1 and d2 is the distance L4 between the suspended edge 1171 of the first window 1111 and the upper end of the matrix segment 203, which satisfies: 0mm≤L4≤5mm. In addition, in combination with Figure 5, the longitudinal length L3 of the matrix segment 203 is greater than the length L1" of the longitudinal edge 1113 of the first window 1111. In this way, when the lower end of the matrix segment 203 reaches the lower end of the longitudinal edge 1113 during the process of the aerosol generating product 200 being withdrawn from the first cavity 13, the upper end of the matrix segment 203 is surrounded by the first part 116 and the second part 117 at the same time, thereby preventing the matrix segment 203 from falling from the window 111. With the above structure, the longitudinal dimension of the window 111 can be made large enough to facilitate the entry of the cleaning tool into the first cavity 13. At the same time, it can also effectively prevent the matrix segment 203 of the aerosol generating product 200 remaining in the first cavity 13 of the accommodating tube 10 from falling through the window 111, thereby falling into the receiving cavity for receiving the accommodating tube 10 in the aerosol generating device.

[0065] The aerosol generating device 100 of the embodiment of the present application includes a containing tube 10, which is provided with an opening 12, a first cavity 13 for accommodating at least a part of the aerosol generating product 200, and a base 14 for supporting the bottom of the aerosol generating product 200, wherein the first cavity 13 extends longitudinally, and the opening 12 is arranged at the upper end of the containing tube 10 and is configured to allow the aerosol generating product 200 to enter the first cavity 13; a window 111 communicating with the first cavity 13 is provided on the side wall 11 of the containing tube 10, and the side wall 11 of the containing tube 10 includes an inclined portion 112, the lower end of the inclined portion 112 is connected to the base 14, and the upper end of the inclined portion 112 has an inclined edge 1121 defining a part of the boundary of the window 111, and the inclined edge 1121 extends obliquely so that part of the window 111 is inclined relative to the supporting surface 141 of the base 14. By providing an inclined portion 112 on the side wall 11, the size of the window 111 on the side wall 11 can be effectively increased, so as to facilitate the cleaning of the interior of the accommodating tube 10. At the same time, the inclined portion 112 can also support the aerosol generating product 200 inserted in the first cavity 13, thereby preventing the aerosol generating product 200 from tilting.
