[0026] The embodiment of the application discloses an atomization assembly 1 which is applied to a heating non-combustion device and is used for realizing heating and atomization of an aerosol product 30.

[0027] The atomization assembly 1 of the embodiment of the application, please refer to Figures 1 to 3 , comprising an atomization main body 10 and a clamping piece 20, the atomization main body 10 has a containing cavity 14 for containing the aerosol product 30, the containing cavity 14 extends in a first direction, and the containing cavity 14 has an opening 141 at one end of the first direction. The first direction is the up-down direction in the use state of the heating non-combustion device, that is, the length direction of the aerosol product 30, and the aerosol product 30 can be inserted into the containing cavity 14 from the opening 141 of the containing cavity 14 in the first direction, so as to realize installation and fixation of the aerosol product 30 in the atomization assembly 1.

[0028] Please refer to Figure 2The clamping piece 20 is installed at the opening end of the accommodating cavity 14 in the first direction. The clamping piece 20 is an annular structure arranged around the accommodating cavity 14. In some embodiments, the atomization body 10 has a mounting groove 114 at the opening end of the accommodating cavity 14. The groove opening of the mounting groove 114 faces the first direction. The clamping piece 20 is located in the mounting groove 114. The position of the clamping piece 20 in the radial direction of the clamping piece 20 can be limited by the groove side wall of the mounting groove 114. The clamping piece 20 can be clamped and fixed in the axial direction between the shell 40 of the heat-not-burn device and the atomization body 10. In this way, the relative fixation of the clamping piece 20 and the atomization body 10 is achieved.

[0029] In some embodiments, a limiting groove can also be arranged on the atomization body 10 near the opening end of the accommodating cavity 14. The groove opening of the limiting groove faces the center position of the clamping piece 20 in the radial direction of the clamping piece 20. The clamping piece 20 is located in the limiting groove. The clamping piece 20 is made of an elastic rubber material that can be elastically deformed. The clamping piece 20 can be deformed by extrusion to be installed in the limiting groove. The relative fixation of the clamping piece 20 and the atomization body 10 is achieved.

[0030] In the atomization assembly 1, the clamping piece 20 has a plurality of clamping portions 21. The clamping portions 21 are arranged protruding towards the center of the clamping piece 20 in the radial direction of the clamping piece 20. The plurality of clamping portions 21 are uniformly arranged in the circumferential direction of the clamping piece 20 to clamp and fix the outer circumferential surface of the aerosol product 30. In this way, the clamping force of the clamping piece 20 on the aerosol product 30 is uniformly arranged in the circumferential direction of the clamping piece 20. The aerosol product 30 can be prevented from tilting or even falling out. Adjacent two clamping portions 21 in the plurality of clamping portions 21 are arranged at intervals. The recess between the adjacent two clamping portions 21 is used to form the first air inlet channel 23 with the aerosol product 30.

[0032] In some embodiments, the first air inlet passage 23 is provided with a plurality of first air inlet passages 23, each of which is arranged between two adjacent clamping portions 21 in the circumferential direction of the clamping member 20. Or in some embodiments, the first air inlet passage 23 is provided with only one first air inlet passage 23, and only one pair of adjacent clamping portions 21 is provided with the first air inlet passage 23.

[0033] For the first passage wall surface 231 which is farther away from the aerosol generating article 30, please refer to Figure 2 , the first passage wall surface 231 has a first end 232 and a second end 233 at both ends of the first direction, wherein the first end 232 is away from the second passage wall surface 234, and the second end 233 is close to the second passage wall surface 234, and the distance between the first passage wall surface 231 and the aerosol generating article 30 gradually decreases from the first end 232 to the second end 233, so that the distance between the first passage wall surface 231 and the aerosol generating article 30 gradually decreases from the far end of the narrow passage to the close end of the narrow passage, on the one hand, the airflow can be guided into the narrow passage through the first passage wall surface 231, on the other hand, the bending angle of the airflow in the first air inlet passage 23 can be reduced, the resistance of the bending passage in the first air inlet passage 23 to the airflow is reduced, and the airflow sound of the airflow flowing through the first air inlet passage 23 is further reduced.

[0034] In some embodiments, the first passage wall surface 231 is a curved surface, or the first passage wall surface 231 can also be part of a conical surface, so as to facilitate the processing and manufacturing of the first passage wall surface 231.

[0035] In some embodiments, the first passage wall surface 231 can also extend along the first direction, as long as the length of the narrow passage in the first air inlet passage 23 can be reduced through the first passage wall surface 231.

[0036] In some embodiments, the first channel wall surface 231 arranged in the first direction and the second channel wall surface 234 are connected by a curved surface smooth transition, which can be connected by an arc surface transition with the same curvature radius, or can be connected by a plurality of arc surface transitions with different curvature radii, so as to avoid forming sharp convex parts on the channel wall surface in the first air inlet channel 23, and to make the airflow flow more smoothly in the first air inlet channel 23, and further reduce the airflow sound when the airflow flows through the first air inlet channel 23.

[0037] Of course, in some embodiments, the first channel wall surface 231 and the second channel wall surface 234 can also be connected by a plurality of planes.

[0038] In some embodiments, please refer to Figure 2 and Figure 3 , the atomization main body 10 further has a second air inlet channel 117 and an air inlet cavity 16, the second air inlet channel 117 is arranged around the containing cavity 14, the second air inlet channel 117 is located on the side of the first air inlet channel 23 away from the opening 141 of the containing cavity 14 in the first direction, the second air inlet channel 117 is in communication with the first air inlet channel 23, the air inlet cavity 16 is located on the side of the containing cavity 14 away from the clamping member 20 in the first direction, the air inlet cavity 16 is in communication with the second air inlet channel 117 and the containing cavity 14, and external air can enter the containing cavity 14 from the opening 141 of the containing cavity 14, sequentially along the first air inlet channel 23, the second air inlet channel 117 and the air inlet cavity 16, so as to realize air supply for the aerosol product 30 in the containing cavity 14.

[0039] Specifically, please continue to refer to Figure 2 and Figure 3 , the atomization main body 10 includes an atomization support 11, an atomization base 12, a sealing base 15 and a heating cylinder 13, the atomization support 11 has a cylinder structure 111, the cylinder structure 111 extends in the first direction, the cylinder structure 111 is arranged around the containing cavity 14, the cylinder structure 111 has a first mounting port 112 and a second mounting port 113 at both ends in the first direction, the cylinder structure 111 forms a mounting groove 114 at the second mounting port 113, the mounting groove 114 is used for mounting the clamping member 20, the atomization base 12 is mounted at the first mounting port 112, the atomization support 11 has an inner convex part at the second mounting port 113, and the groove bottom wall of the mounting groove 114 is located on the inner convex part, the heating cylinder 13 is located in the cylinder structure 111, and the heating cylinder 13 is clamped and fixed between the atomization base 12 and the inner convex part in the first direction, so as to realize the mounting and fixation of the heating cylinder 13 in the atomization main body 10; the atomization support 11, the heating cylinder 13 and the atomization base 12 enclose the containing cavity 14.

[0040] The sealing base 15 is made of an elastically deformable material, such as rubber, and is mounted at the first mounting opening 112 of the atomizing support 11. The sealing base 15 is sleeved on the barrel structure 111 and sealingly engages with the outer wall surface of the barrel structure 111. The sealing base 15 is located on the side of the atomizing base 12 away from the accommodating cavity 14 in the first direction. The atomizing base 12 is clamped and fixed between the sealing base 15 and the atomizing support 11 in the first direction. In this way, the relative positions of the components in the atomizing body 10 are fixed.

[0041] In some embodiments, referring to Figure 2 The second air inlet channel 117 can be arranged in the barrel wall of the barrel structure 111, or in other embodiments, the second air inlet channel 117 can also be arranged between the barrel structure 111 and the heating barrel 13. The second air inlet channel 117 is an annular channel arranged around the accommodating cavity 14. The barrel structure 111 has a through hole 115 that communicates the first air inlet channel 23 and the second air inlet channel 117. The through hole 115 extends in the first direction. The first air inlet channel 23 is provided at only one position in the circumferential direction of the clamping piece 20. The atomizing support 11 is provided with a limiting structure between the mounting groove 114 and the clamping piece 20. The limiting structure includes a limiting protrusion 116 provided on one of the atomizing support 11 and the clamping piece 20 and a limiting recess 22 provided on the other. The limiting protrusion 116 cooperates with the limiting recess 22 to limit the rotation of the clamping piece 20 in the mounting groove 114. In this way, the first air inlet channel 23 and the through hole 115 on the barrel structure 111 are arranged correspondingly in the first direction.

[0042] The atomizing base 12 has a plurality of air inlet holes 121 that communicate with the accommodating cavity 14 at the position of the accommodating cavity 14. The air inlet cavity 16 is located between the atomizing base 12 and the sealing base 15. The atomizing support 11 and the atomizing base 12 are provided with a communication groove 151, or the communication groove 151 is provided on the sealing base 15. The sealing base 15, the atomizing support 11, and the atomizing base 12 enclose a communication hole at the communication groove 151. The second air inlet channel 117 can communicate with the air inlet cavity 16 through the communication hole. In this way, the airflow in the first air inlet channel 23 can enter the accommodating cavity 14 through the through hole 115, the second air inlet channel 117, the communication hole, the air inlet cavity 16, and the air inlet hole 121 in sequence, thereby supplying air to the aerosol generating article 30.

[0043] In some embodiments, in order to facilitate the installation and positioning of the atomization base 12, the sealing base 15 and the atomization support 11 in the circumferential direction of the cylinder structure 111, a protrusion is arranged on the sealing base 15 and the atomization base 12, and a recess is arranged on the corresponding atomization support 11. The protrusion and the recess are matched to limit the rotation of the sealing base 15 and the atomization base 12 in the circumferential direction of the atomization support 11, and can also avoid the cylinder structure 111 of the atomization support 11 from blocking the communication hole, thereby ensuring that the airflow in the second air inlet channel 117 enters the air inlet cavity 16.

[0044] In some embodiments, the sealing base 15 is cancelled in the atomization body 10, and a support cylinder is arranged instead of the heating cylinder 13. The support cylinder does not have a heating function. In addition, a heating element extending into the accommodation cavity 14 is arranged on the atomization base 12. The heating element is used to pierce into the aerosol product 30 to heat the aerosol product 30. The second air inlet channel 117 can be located between the support cylinder and the aerosol product 30. A protrusion is arranged on the atomization base 12, and the protrusion abuts against the aerosol product 30 in the first direction. The air inlet cavity 16 is located between the atomization base 12 and the aerosol product 30. The airflow in the first air inlet channel 23 can enter the aerosol product 30 in sequence through the second air inlet channel 117 and the air inlet cavity 16 to supply air to the aerosol product 30.

[0045] The application also provides a heating non-combustion device, please continue to refer to Figures 1 to 3 The heating non-combustion device includes a shell 40 and the atomization assembly 1 in any of the above embodiments. The atomization assembly 1 is installed in the shell 40. A support 43 is arranged in the shell 40. The atomization assembly 1 can be fixed in the shell 40 by the support 43 and the limiting structure on the shell 40 to avoid shaking of the atomization assembly 1 in the shell 40. For example, the atomization assembly 1 as a whole can be clamped and fixed between the support 43 and the local part of the shell 40 in the first direction to realize the relative fixation of the atomization assembly 1 and the shell 40.

[0046] The shell 40 has a plug-in opening 41 communicating with the accommodation cavity 14. The aerosol product 30 can be inserted into the accommodation cavity 14 from the plug-in opening 41 and the opening 141 of the accommodation cavity 14. The clamping piece 20 in the atomization assembly 1 can be clamped and fixed between the shell 40 and the atomization support 11 of the atomization body 10 in the first direction. In this way, the relative fixation of the clamping piece 20, the shell 40 and the atomization body 10 is realized.

[0047] In some embodiments, the housing 40 can form a third air inlet channel 42 with the aerosol article 30 at the insertion opening 41, the third air inlet channel 42 being arranged around the aerosol article 30, the third air inlet channel 42 being in communication with the first air inlet channel 23, and air outside the housing 40 can enter the first air inlet channel 23 from the third air inlet channel 42, and then enter the accommodation cavity 14 from the second air inlet channel 117 and the air inlet cavity 16.

[0048] In some embodiments, the housing 40 has a third channel wall surface 421 and a fourth channel wall surface 424 at the third air inlet channel 42, the third channel wall surface 421 and the fourth channel wall surface 424 being arranged in the first direction, and in the radial direction of the clamping member 20, the distance between the third channel wall surface 421 and the aerosol article 30 is greater than the distance between the fourth channel wall surface 424 and the aerosol article 30, so that the cross-sectional size of the third air inlet channel 42 at the third channel wall surface 421 can be increased by the third channel wall surface 421 being farther away from the aerosol article 30, thereby reducing the channel length of the third air inlet channel 42 at the fourth channel wall surface 424, i.e., reducing the length of the narrow air inlet channel in the third air inlet channel 42, thereby reducing the airflow sound of the airflow flowing through the third air inlet channel 42, i.e., reducing the airflow sound of the entire heat-not-burn device, and improving the user experience.

[0049] In some embodiments, for the third channel wall surface 421, please refer to Figure 2 and Figure 3 , the third channel wall surface 421 has a third end 422 and a fourth end 423 at both ends of the first direction, wherein the third end 422 is away from the fourth channel wall surface 424 in the first direction, and the fourth end 423 is close to the third channel wall surface 421 in the first direction, and the distance between the third channel wall surface 421 and the aerosol article 30 gradually decreases from the third end 422 to the fourth end 423, so that the distance between the third channel wall surface 421 and the aerosol article 30 gradually decreases from far away from the narrow channel to close to the narrow channel, which can guide the airflow to enter the narrow channel through the third channel wall surface 421 on the one hand, and can also reduce the bending angle of the airflow in the third air inlet channel 42, reduce the obstruction of the bending channel in the third air inlet channel 42 to the airflow, and further reduce the airflow sound of the airflow flowing through the third air inlet channel 42 on the other hand.

[0050] In some embodiments, the third channel wall surface 421 is a curved surface, or the third channel wall surface 421 can also be a conical surface, so as to facilitate the processing and manufacturing of the third channel wall surface 421.

[0051] In some embodiments, the third channel wall 421 can be omitted, the sidewall of the insertion port 41 on the housing 40 extends in the first direction, and the cross-sectional dimensions of the third air intake channel 42 formed by the housing 40 and the aerosol product 30 are such that no airflow noise is generated when the airflow passes through the third air intake channel 42.

[0052] In some embodiments, please continue to refer to Figure 2 and Figure 3 The distance between the third channel wall 421 and the aerosol product 30 is greater than the distance between the fourth channel wall 424 and the aerosol product 30. The third channel wall 421 and the fourth channel wall 424 are connected by a smooth transition through curved surfaces in the first direction. For example, they can be connected by arc surfaces with the same radius of curvature, or by multiple arc surfaces with different radii. This avoids the formation of sharp protrusions on the channel wall in the third air intake channel 42, making the airflow in the third air intake channel 42 smoother and further reducing the airflow noise when the airflow passes through the third air intake channel 42.

[0053] In some embodiments, please refer to Figure 2 The fourth channel wall 424 is located in the first direction on the side facing the clamping member 20 of the third channel wall 421, that is, the side facing the inside of the housing 40. In this way, during the process of inserting the aerosol product 30 into the receiving cavity 14, the curved or conical third channel wall 421 can guide the aerosol product 30, making it easier for the aerosol product 30 to be inserted.

[0054] In some embodiments, please continue to refer to Figure 2 The second channel wall 234 on the clamping member 20 is located between the first channel wall 231 and the fourth channel wall 424 in the first direction. This makes it adjacent to the second channel wall 234 and the fourth channel wall 424, which are relatively close to the aerosol product 30. This helps to reduce the bending angle of the airflow between the third air intake channel 42 and the first air intake channel 23, reduce the obstruction of the airflow by the bending channel, reduce or even avoid the airflow noise when the airflow passes through the third air intake channel 42 and the first air intake channel 23, and improve the user experience.

[0055] In some embodiments, the distance between the second channel wall 234 and the aerosol product 30 is less than the distance between the fourth channel wall 424 and the aerosol product 30, thus forming a narrow channel only between the second channel wall 234 and the aerosol product 30, thereby reducing the length of the narrow channel and further reducing airflow noise. In other embodiments, the distance between the second channel wall 234 and the aerosol product 30 can be set to be equal to the distance between the fourth channel wall 424 and the aerosol product 30, in order to reduce the bending angle of the airflow at the third air intake channel 42 and the first air intake channel 23.

[0056] The utility model is described above with specific examples, which is only used for helping to understand the utility model and does not limit the utility model. For the skilled in the art to which the utility model belongs, according to the idea of the utility model, a number of simple deductions, deformations or substitutions can be made.
