DETAILED DESCRIPTION

[0027] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0028] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations, and the operation steps involved in each embodiment can also be replaced or adjusted in a sequence in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0029] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0030] The embodiment of the present application discloses an atomization component, which can be used in a heat-not-burn device to heat an aerosol generating substrate 3 so that the aerosol generating substrate 3 generates aerosol and discharges it from a gas channel in the heat-not-burn device.

[0031] In the present application, please refer to Figure 2 The atomizing assembly includes a connecting tube, a heating element 21 and a sealing element. The heating element 21 includes a heating tube 211. The heating element 21 abuts against the connecting tube in the axial direction of the heating tube 211. The heating tube 211 is connected to the gas channel in the heating non-combustion device through the connecting tube. The outer circumferential surface of the heating tube 211 and the connecting tube are spaced apart in the radial direction of the heating tube 211. The sealing element is sealingly sleeved on the connecting tube. The sealing element has a supporting arm. The supporting arm is located on the side of the connecting tube facing the heating tube 211 in the axial direction of the heating tube 211, and the supporting arm is sealingly abutted against the outer circumferential surface of the heating tube 211.

[0032] Since the heating element 21 is abutted against the connecting tube in the axial direction of the heating tube 211, the outer circumferential surface of the heating tube 211 and the connecting tube are spaced apart in the radial direction of the heating tube 211, and the outer circumferential surface of the heating tube 211 is only sealed and abutted against the abutting arm of the sealing element. On the one hand, this can reduce the contact area between the heating tube 211 and the connecting tube, which helps to reduce the heat transferred from the heating tube 211 to the connecting tube in its axial direction, thereby reducing the energy consumption of the entire atomization assembly; on the other hand, the sealing performance of the connecting tube and the heating tube 211 can be ensured by the sealing element, thereby reducing the hot air flow and aerosol overflowing from the inside of the heating tube 211 to the outside, which helps to improve the taste and can further reduce the energy consumption of the atomization assembly and the entire heating without burning device.

[0033] Specifically, please refer to Figure 2 In an atomizing assembly of an embodiment, the heating tube 211 may be a round tube structure, and the corresponding connecting tube may be a round tube structure, and the heating tube 211 and the connecting tube are arranged coaxially; a mounting groove may be provided at the end of the connecting tube, and the heating element 21 is plugged into and matched with the mounting groove in the axial direction of the heating tube 211, and the end of the heating element 21 may fit with the bottom wall of the mounting groove to meet the requirement that the heating element 21 abuts against the connecting tube in the axial direction of the heating tube 211; the outer peripheral surface of the heating tube 211 is spaced apart from the side wall of the mounting groove to meet the requirement that ... The heat pipe 211 is radially spaced from the connecting tube to avoid contact between the outer circumference of the heating tube 211 and the connecting tube. Of course, in other embodiments, the end of the connecting tube may not be provided with a mounting groove, and the axial end face of the connecting tube may directly abut and fit with the end face of the heating element 21. This can also avoid direct contact between the outer circumference of the heating tube 211 and the connecting tube, and can effectively reduce the contact area between the heating tube 211 and the connecting tube. The energy consumption of the entire atomization assembly can be reduced by reducing the heat transfer between the heating tube 211 and the connecting tube.

[0034] In one embodiment, please refer to Figure 2 and Figure 5 As for the seal, the seal is sealingly sleeved on the connecting tube, and the seal has a sealing ring and a supporting arm connected to the sealing ring. The sealing ring is arranged around the connecting tube, and the sealing ring is sleeved on the connecting tube. The sealing ring and the connecting tube are sealed and matched. The supporting arm is an annular structure continuously arranged around the connecting tube, and a convex portion can be provided on the outer side wall of the connecting tube to limit the seal from moving on the connecting tube in a direction away from the heating tube 211; the supporting arm is cantilevered on the side of the connecting tube facing the heating tube 211 in the axial direction of the heating tube 211, and the supporting arm is arranged around the heating tube 211, and the supporting arm is also sealed and fitted with the outer peripheral surface of the heating tube 211, so that the sealing connection between the connecting tube and the heating tube 211 is realized through the seal.

[0035] Further, in one embodiment, please continue to refer to Figure 2 , the abutment arm extends from the sealing ring toward the heating tube 211, and the abutment can extend in the radial direction of the heating tube 211; of course, in other embodiments, the extension direction of the abutment arm can be arranged at an acute angle to the extension direction of the heating tube 211. The abutment arm has a connection end connected to the sealing ring in its extension direction, and also has an abutment end that is sealed and abutted with the heating tube 211; when the seal is in a free state, the inner diameter of the abutment arm at the abutment end is smaller than the inner diameter at the connection end, and the inner diameter of the abutment arm at the abutment end is smaller than the outer diameter of the heating tube 211, so that the abutment end of the abutment arm can be sealed and abutted on the outer peripheral surface of the heating tube 211, so that the sealing performance of the axial connection position of the connecting tube and the heating tube 211 can be ensured by the sealing cooperation of the sealing member with the connecting tube and the heating tube 211 respectively, which can reduce or even avoid the overflow of hot air flow and aerosol from the connection position of the connecting tube and the heating tube 211, while improving the taste of use, it can also reduce heat loss and reduce the energy consumption of the atomization component.

[0036] In other embodiments, the supporting arm can be arranged so that the middle part and the supporting end in the length direction are sealed against the outer peripheral surface of the heating tube 211. In this way, the sealing performance of the connection position between the connecting tube and the heating tube can be ensured by the sealing member respectively cooperating with the sealing of the connecting tube and the heating tube 211.

[0037] In one embodiment, please continue to refer to Figure 2 and Figure 5The abutting arm has a first side surface arranged toward the connecting tube in the axial direction of the heating tube 211 and a second side surface arranged away from the connecting tube, and also has an inner end surface connecting the first side surface and the second side surface. The inner end surface of the abutting arm is the innermost end surface in the radial direction of the heating tube 211, and the areas of the first side surface and the second side surface are both larger than the area of ​​the end surface. A structure in which the extension direction of the abutting arm and the extension direction of the heating tube 211 are arranged at an acute angle can be provided, so that the first side surface of the abutting arm is arranged toward the heating tube 211 in the radial direction of the heating tube 211, and the outer peripheral surface of the heating tube 211 can be sealed by the first side surface of the abutting arm at the abutting end, so that the sealing area between the abutting arm and the outer peripheral surface of the heating tube 211 can be increased, and the sealing performance between the heating tube 211 and the sealing member can be improved.

[0038] Of course please refer to Figure 2 In the structure in which the supporting arm is extended in the radial direction of the heating tube 211, the sealing between the first side surface of the supporting end and the outer peripheral surface of the heating tube 211 can also be satisfied. In the embodiment in which the inner diameter of the supporting arm is much smaller than the outer diameter of the heating tube 211, the sealing between the first side surface on the supporting end and the outer peripheral surface of the heating tube 211 can be achieved by deformation of the supporting arm on the sealing member.

[0039] In order to facilitate the deformation of the supporting arm on the sealing member, the sealing member is set to be a rubber member, and the rubber member has good elastic deformation ability, so that the supporting arm of the sealing member is pressed against the outer peripheral surface of the heating tube 211, ensuring a good seal between the sealing member and the heating tube 211. Of course, in other embodiments, the sealing member can also be other plastic members with elastic deformation ability.

[0040] In one embodiment, please refer to Figure 2 and Figure 5 In the process of sealing and matching the sealing member with the heating tube 211, in order to prevent the sealing ring from deforming with the abutting arm, the cross-sectional dimension of the connecting end is larger than the cross-sectional dimension of the abutting end in the extending direction of the abutting arm. In this way, the deformation capacity of the abutting end of the abutting arm is larger than the deformation capacity of the connecting end. When the abutting end is deformed, the deformation of the connecting end and the entire sealing ring can be reduced, thereby ensuring the sealing performance of the sealing member and the connecting tube.

[0041] Since the abutment arm is an annular structure surrounding the heating tube 211 and the abutment arm extends toward the heating tube 211, the cross-sections of the connecting end and the abutment end on the abutment arm are both perpendicular to the extension direction of the abutment arm. The abutment arm is provided with a thickness direction perpendicular to its extension direction. The cross-sectional dimension of the connecting end is larger than the cross-sectional dimension of the abutment end. It can also be understood that the thickness dimension of the abutment arm at the connecting end is larger than the thickness dimension at the abutment end.

[0042] For example, it can be arranged that in the extension direction of the abutment arm, the thickness of the abutment arm gradually decreases from the connection end to the abutment end; of course, it can also be arranged as follows Figure 2 The thickness of the middle abutting wall is arranged in a stepped manner in its extending direction, and the abutting arm has only two thicknesses, one thickness being a larger thickness at the connecting end, and the other thickness being a smaller thickness at the abutting end.

[0043] In one embodiment, please continue to refer to Figure 2 The gas channel includes an air inlet channel and an air outlet channel. There are two connecting tubes, which include a first connecting tube 22 and a second connecting tube 23. In the axial direction of the heating tube 211, the heating element 21 is clamped between the first connecting tube 22 and the second connecting tube 23. The heating tube 211 is connected to the air inlet channel through the first connecting tube 22, and the heating tube 211 is also connected to the air outlet channel through the second connecting tube 23. In this way, connection positions with the first connecting tube 22 and connection positions with the second connecting tube 23 are respectively formed at both ends of the axial direction of the heating tube 211.

[0044] Please continue to refer to Figure 2 In the axial direction of the heating tube 211, a first mounting groove can be provided at the end of the first connecting tube 22 facing the heating tube 211, one end of the heating tube 211 is inserted into the first mounting groove, the end face of one end of the heating tube 211 is in contact with the bottom wall of the first mounting groove, and the outer peripheral surface of the heating tube 211 is spaced apart from the side wall of the first mounting groove; in addition, a second mounting groove is provided at the end face of the second connecting tube 23 facing the heating tube 211, the other end of the heating tube 211 is inserted into the second mounting groove, the end face of one end of the heating tube 211 is in contact with the bottom wall of the second mounting groove, and the outer peripheral surface of the heating tube 211 is spaced apart from the side wall of the second mounting groove.

[0045] In order to ensure the sealing of the connection between the two axial ends of the heating tube 211 and the first connecting tube 22 and the second connecting tube 23, two sealing members are provided. Figure 2 and Figure 5 The two seals include a first seal 24 and a second seal 25. The first seal 24 seals the connection position between the first connecting tube 22 and the heating tube 211, and the second seal 25 seals the connection position between the second connecting tube 23 and the heating tube 211. The structures of the first seal 24 and the second seal 25 are substantially the same. The first seal 24 has a first sealing ring 241 and a first abutting arm 242 connected to the first sealing ring 241. The second seal 25 has a second sealing ring 251 and a second abutting arm 252 connected to the second sealing ring 251. The first abutting arm 242 has a first connecting end 2421 connected to the first sealing ring 241, and also has a first abutting end 2422 that is sealed and abutted with the heating tube 211. The second abutting arm 252 has a second connecting end 2521 connected to the second sealing ring 251, and also has a second abutting end 2522 that is sealed and abutted with the heating tube 211.

[0046] The above-mentioned sealing ring includes a first sealing ring 241 and a second sealing ring 251, the abutting arm includes a first abutting arm 242 and a second abutting arm 252, the connecting end includes a first connecting end 2421 and a second connecting end 2521, and the abutting end includes a first abutting end 2422 and a second abutting end 2522; the first sealing ring 241 is sealingly sleeved on the first connecting tube 22, and the second sealing ring 251 is sealingly sleeved on the second connecting tube 23, the first abutting arm 242 and the second abutting arm 252 both extend toward the heating tube 211, the first abutting arm 242 or its first abutting end 2422 is sealingly abutted with the outer peripheral surface of the heating tube 211, and the second abutting arm 252 or its second abutting end 2522 is also sealingly abutted with the outer peripheral surface of the heating tube 211, so as to respectively realize the sealing of the first connecting tube 22, the second connecting tube 23 and the heating tube 211.

[0047] In other embodiments, there may be only one connecting tube and only one sealing member, and the connecting tube may be the first connecting tube 22 and the sealing member may be the first sealing member 24; or the connecting tube may be the second connecting tube 23 and the sealing member may be the second sealing member 25. In the embodiment where only one connecting tube and one sealing member are provided, the other end of the heating tube 211 may be inserted and matched with the cylinder body, and a positioning groove is provided at the end of the cylinder body so that the end face of the other end of the heating tube 211 fits with the bottom wall of the positioning groove, and the outer peripheral surface of the heating tube 211 fits with the side wall of the positioning groove, so as to fix the position of the other end of the heating tube 211. The atomizing assembly with such a structure can also reduce heat loss and energy consumption to a certain extent.

[0048] In one embodiment, please refer to Figure 2 The atomization assembly also includes an insulation tube 26, which is located on the outside of the heating tube 211 in the radial direction of the heating tube 211. The insulation tube 26 is coaxially arranged with the heating tube 211. The insulation tube 26 is sealed with the first connecting tube 22 and the second connecting tube 23 respectively. The insulation tube 26, the first connecting tube 22, the second connecting tube 23 and the heating tube 211 are enclosed to form an insulation cavity 28. Insulation can be achieved through the insulation cavity 28 to limit the heat transfer of the heating tube 211 to the outside.

[0049] Furthermore, an aerogel layer 27 is attached to the inner wall or outer wall of the insulation tube 26, and the aerogel layer 27 can further limit the heat transfer to the outside of the insulation tube 26, thereby reducing heat loss and reducing the energy consumption of the atomization component. The aerogel layer 27 located on the inner wall of the insulation tube 26 can be attached to the inner wall of the insulation tube 26 by the tension of the aerogel layer 27 itself to limit the position of the inner wall aerogel layer 27, and the aerogel layer 27 located on the outer wall of the insulation tube 26 can be fixed to the outer wall of the insulation tube 26 by gluing.

[0050] Of course, in other embodiments, in order to further reduce heat loss and lower energy consumption, an aerogel layer 27 may be provided on both the inner wall and the outer wall of the insulation tube 26 .

[0051] In the embodiment where only one connecting tube is provided, one end of the heat insulation tube 26 is sealed with the connecting tube, and the other end is sealed with the cylinder body.

[0052] In one embodiment, no matter there is one or two connecting tubes, the connecting tubes include a first connecting tube 22, please refer to Figure 2 , the first connecting tube 22 is located upstream of the heating tube 211 in the air intake direction. The heating element 21 is provided with a heat exchange core 212, the heat exchange core 212 includes a heat exchange portion 2121 and an outer flange 2125, in the axial direction of the heating tube 211, the outer flange 2125 is connected to one end of the heat exchange portion 2121, the outer diameter of the outer flange 2125 is larger than the outer diameter of the heat exchange portion 2121, the heat exchange portion 2121 is located in the heating tube 211, the outer flange 2125 is located on one axial side of the heating tube 211, the outer flange 2125 can be clamped between the heating tube 211 and the first connecting tube 22 in the axial direction of the heating tube 211, so as to realize the fixed connection between the heat exchange portion 2121 and the heating tube 211, so as to avoid direct contact between the heating tube 211 and the first connecting tube 22, which helps to reduce the heat transfer between the heating tube 211 and the first connecting tube 22, and further reduce the energy consumption of the atomization assembly.

[0053] In other embodiments, the heat exchange core 212 may also include only the heat exchange part 2121, and the heat exchange part 2121 is interference fit with the heating tube 211, or a limiting protrusion is provided on the inner wall surface of the heating tube 211 to limit the position of the heat exchange part 2121 in the heating tube 211.

[0054] In one embodiment, please refer to Figure 2 and Figure 3The heating tube 211 has a containing cavity and a heat exchange cavity arranged in its axial direction.

In the radial direction of the heating tube 211, the heating element includes a first heating element 2112 located outside the heat exchange cavity and a second heating element 2113 located outside the containing cavity. The first heating element 2112 and the second heating element 2113 are arranged at intervals in the axial direction of the heating tube 211. The heat of the first heating element 2112 is transferred to the heat exchange part 2121 through the heating tube 211. The heat exchange part 2121 is used to heat the airflow passing through the heat exchange airway 2122 therein. After the airflow passes through the heat exchange airway 2122 and is heated, it enters the containing cavity to heat the aerosol generating matrix 3. On the one hand, the second heating part 2113 can heat the aerosol generating matrix 3 through the heating tube 211 to make the aerosol generating matrix 3 generate aerosol.
