[0032] The present application will be further described in detail by specific embodiments in conjunction with the accompanying drawings. In different embodiments, similar elements are denoted by associated similar element reference numbers. In the following embodiments, many details are described in order to make the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by other elements, materials, 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 it is not necessary to describe these related operations in detail for those skilled in the art according to the description in the specification and general technical knowledge in the art.

[0033] ​In addition, the features described in the specification, operations or characteristics can be combined in any appropriate manner to form various embodiments, and the steps involved in each embodiment can be sequentially adjusted or adjusted in a manner that can be apparent to those skilled in the art. Therefore, the description and drawings are only for the purpose of clearly describing one embodiment, and do not mean the necessary composition and / or order.

[0034] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and have no technical meaning. Unless otherwise specified, "connection" and "coupling" in this application include direct and indirect connections (couplings).

[0035] The aerosol generating stick is a substrate containing an atomized substrate, which can be used with the corresponding atomizing equipment to heat the aerosol generating stick to atomize the atomized substrate therein and generate aerosol. Different materials of the atomized substrate have different tastes after being atomized to meet different user needs.

[0036] The heating base provided by the present application can be applied to an atomizing equipment (such as a heat-not-burn equipment) to heat and atomize an aerosol generating stick. By arranging a first air channel extending spirally and communicating with the insertion port in the base body, and arranging a corresponding second air channel on the inner end face of the base bottom wall of the base body, and the second air channel communicates with the first air channel and the heating hole on the base bottom wall, when the aerosol generating stick is loaded into the heating cavity of the heating base, the airflow can enter from the insertion port and move spirally along the first air channel to the base bottom wall, and then move to the heating hole through the second air channel. When applied to an atomizing equipment, the heating hole on the cavity bottom wall of the heating cavity is used to allow the heating member of the atomizing equipment to penetrate into the heating cavity, and to heat and atomize the aerosol generating stick loaded in the heating cavity. The airflow is heated to form a hot airflow during movement along the first air channel and the second air channel. The hot airflow can flow into the interior of the aerosol generating stick from its end face near the heating hole, so as to avoid the direct entry of cold air with lower temperature into the aerosol generating stick to cause cold-hot confrontation, which is beneficial to enhancing the heating effect. Moreover, the airflow moves spirally in the heating cavity, which can effectively reduce the resistance during movement of the airflow, and the airflow power is enhanced, so that the user does not need to exert a large suction force during the suction action, which is beneficial to improving the use experience.

[0037] Some embodiments of the heating base and the atomizing equipment provided by the present application will be described below in combination with the drawings.

[0038] In the embodiments of the first aspect of the present application, a heating base 100 is provided, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the heating base 100 includes a base body 1, which has a base side wall 11 and a base bottom wall 12. The base body 1 has a heating cavity 13 formed by the base side wall 11 and the base bottom wall 12. In a first direction, one end of the base body 1 opposite to the base bottom wall 12 has an insertion port 111, which communicates with the heating cavity 13, for inserting an aerosol generating rod into the heating cavity 13 through the insertion port 111. The base bottom wall 12 has a heating hole 121 communicating with the heating cavity 13, for allowing a heating element to pass through when applied to an atomizing device, so that the heating element can heat the aerosol generating rod in the heating cavity 13. The base sidewall 11 has a first air passage 112 on its inner side, which is spirally arranged in a first direction. One end of the first air passage 112 is connected to the insertion port 111, and the other end extends to the inner end face of the base bottom wall 12. A second air passage 122 is correspondingly provided on the inner end face of the base bottom wall 12. The second air passage 122 is connected to the first air passage 112 and the heating hole 121, so that the airflow of the first air passage 112 can flow along the second air passage 122 to the heating hole 121, and then flow back to the heating chamber 13 from the vicinity of the heating hole 121. Figure 4 , Figure 5 and Figure 6 As shown, with the aerosol generating rod 400 inserted into the heating chamber 13, external airflow can still enter the first air passage 112 of the base body 1 through the insertion port 111. When the user performs a suction action on the aerosol generating rod 400, the airflow moves spirally along the first air passage 112 under negative pressure and is heated to form a hot airflow. When the airflow moves to the bottom wall 12 of the base, it flows along the second air passage 122 towards the inner side of the heating chamber and close to the heating hole 121. Since the heating hole 121 is opposite to the end face of the aerosol generating rod, the airflow can be drawn into the interior of the aerosol generating rod 400 from the end face.

[0039] It is understandable that aerosol generating rods need to be heated during use to atomize the atomizing matrix and produce aerosols. The atomization process has certain requirements for the heating temperature; if the temperature does not reach the preset threshold, the normal atomization effect will be affected. The atomized aerosol needs to be carried to the suction end by the airflow generated by the suction action. Therefore, if the temperature of the intake airflow is low (e.g., cold air), it will create a thermal shock effect on the atomizing matrix after entering the aerosol generating rod, thus lowering the temperature of the atomizing matrix and affecting the atomization effect.

[0040] The heating base 100 in the embodiment can form top air inlet by the first air channel 112 spirally arranged in the base body 1 when the aerosol generating stick is assembled in the heating cavity 13, and the airflow can move along the first air channel 112 spirally to the base bottom wall 12 and move along the second air channel 122 to the direction close to the heating hole 121. The airflow is heated to form hot airflow during the movement, and is inhaled into the inside of the aerosol generating stick near the heating hole 121, so as to avoid the cold air directly entering the inside of the aerosol generating stick to cause cold and hot confrontation, and to facilitate to enhance the heating effect. Moreover, the spiral airflow formed can effectively reduce the resistance during the movement, and the airflow force is stronger, so that the user does not need large suction force when performing the suction action, and the use experience is improved.

[0041] In addition, since the heating base 100 has a complete air inlet channel, when applied to the atomization equipment, it is not necessary to additionally arrange the air channel in the shell of the atomization equipment, and the structural design of the whole machine is facilitated.

[0042] It should be noted that the number of the first air channel 112 and the second air channel 122 in the embodiment can be one or more, and the rotation direction of the first air channel 112 can be selected according to actual conditions, and is not limited to the clockwise direction shown in the drawings of the embodiment.

[0043] In further embodiments of the present application, as shown in Figure 4 、 Figure 7 and Figure 8 , the first air channel 112 specifically includes a first spiral groove 1121, the first spiral groove 1121 penetrates the inner side surface of the base side wall 11 in the lateral direction, that is, the first spiral groove 1121 is formed by the inner side surface of the base side wall 11 being recessed, and the opening side of the first spiral groove 1121 faces the inside of the base body 1. In the first direction, the first spiral groove 1121 is arranged in a spiral shape, one end of the first spiral groove 1121 penetrates the end surface of the base side wall 11 at one end of the insertion port 111, and the other end of the first spiral groove 1121 extends to the inner end surface of the base bottom wall 12 and communicates with the second air channel 122 on the base bottom wall 12. When the aerosol generating stick 400 is assembled into the heating cavity 13, as shown in the state shown in Figure 5 and Figure 6 , the side wall of the aerosol generating stick 400 abuts against or maintains a small gap with the inner side surface of the base side wall 11, the first spiral groove 1121 forms a spiral air channel, and external gas can enter the first spiral groove 1121 from the end surface of the base side wall 11 and move along the first air channel 112 spirally to the inner end surface of the base bottom wall 12 to form a spiral airflow. Compared with the disordered movement state, the airflow force is stronger, the resistance during the movement can be reduced, and the airflow movement is more stable and smooth.

[0044] In actual applications, the cross-sectional shape of the first spiral groove 1121 can be rectangular, semicircular, triangular, etc. Of course, it can also be set to other shapes suitable for airflow passing through as needed. For example, Figure 6 Taking the rectangular shape shown in the figure as an example, the cross-sectional area of the first spiral groove 1121 is in the range of 0.2mm 2 to 5mm 2 , so as to increase the flow area of the first spiral groove 1121 as much as possible while meeting the strength requirements of the base side wall 11.

[0045] In addition, the number of turns and the pitch (i.e., the distance between the corresponding points of two adjacent turns in the first direction) of the first spiral groove 1121 can be set according to the size of the base body 1 in the first direction. When the pitch size of the first spiral groove 1121 is relatively large, multiple first spiral grooves 1121 can be set as needed to further increase the air intake. The multiple first spiral grooves 1121 maintain a certain phase difference in the circumferential direction, are in an alternating state in the first direction, and maintain a certain interval to prevent mutual interference. Taking two first spiral grooves 1121 as an example, the two first spiral grooves 1121 are 180° apart in the circumferential direction, and one of the first spiral grooves 1121 is provided with the other first spiral groove 1121 between the two adjacent turns in the first direction.

[0046] It should be noted that the above is only one preferred example of the first air duct 112, and the first air duct 112 is not limited to the form of the first spiral groove 1121 described above. For example, the first air duct 112 can also be set to a closed hole structure. In another specific example, the first air duct 112 can adopt the form of a first spiral hole, which is located inside the base side wall 11, i.e., no opening is provided on both the inner and outer sides in the lateral direction. The first spiral hole is spirally arranged along the first direction, one end of the first spiral hole penetrates the base side wall 11 and is located at the end face of the insertion port 111, and the other end of the first spiral hole extends to the inner end face of the base bottom wall 12 and communicates with the second air duct 122. The first spiral hole forms a spiral air duct, and external gas can enter the first spiral hole from the end face of the base side wall 11 and move along the first spiral hole to the base bottom wall 12, forming a spiral airflow. By setting the first spiral hole, the airflow intensity can also be increased, and the resistance during airflow movement can be further reduced, improving the stability of airflow movement.

[0047] In further embodiments of the present application, Figure 2 , Figure 7 and Figure 8As shown, on the inner end face of the base bottom wall 12, the second air channel 122 specifically comprises a second spiral groove 1221, the rotation direction of the second spiral groove 1221 is the same as that of the first air channel 112, so that the airflow can smoothly transition when moving from the first air channel 112 to the second air channel 122. The second spiral groove 1221 specifically presents a state of gradually shrinking to the center position from the outside to the inside, and one end of the second spiral groove 1221 close to the edge is in communication with the first air channel 112, and the other end of the second spiral groove 1221 is in communication with the heating hole 121. After the airflow enters the second air channel 122 from the first air channel 112, it can continue to flow to the heating hole 121 in a spiral state. By setting the second spiral groove 1221, the airflow can continue to maintain a spiral motion state when flowing on the inner end face of the base bottom wall 12, which can avoid the phenomenon of sudden change of airflow movement direction, reduce airflow impact and disturbance, and at the same time reduce resistance, which is beneficial to the smooth flow of the airflow to the heating hole 121.

[0048] In actual application, when a plurality of first air channels 112 are provided, a plurality of second spiral grooves 1221 can also be provided correspondingly, and similar setting methods are adopted, so that each second spiral groove 1221 is in communication with one of the first air channels 112, so that multiple airflows can move independently to prevent mutual interference. In addition, the second spiral groove 1221 can also adopt a similar structure form as the first air channel 112, for example, the cross-sectional shape can adopt a rectangle, a semicircle, a triangle, etc., and the width of the second spiral groove 1221 can be set according to the space position on the base bottom wall 12, such as the examples in Figure 7 and Figure 8 , the width of the second spiral groove 1221 can be increased in a larger space area, and the width of the second spiral groove 1221 can be reduced near the base side wall 11 and near the heating hole 121 to adapt to the first air channel 112 and the heating hole 121, and the width of the second spiral groove 1221 is gradually changed to keep the airflow moving smoothly.

[0049] Further, as examples in Figure 3 , Figure 4 and Figure 6 , the heating cavity 13 adopts a cylindrical cavity to adapt to the shape of the aerosol generating stick. Accordingly, the heating hole 121 is located at the center position of the base bottom wall 12 and is coaxially arranged with the heating cavity 13 to correspond to the center area of the end face of the aerosol generating stick 400. After the heating element extends into the heating cavity 13 from the heating hole 121, it can be inserted into the inside of the aerosol generating stick 400 close to the center to make the heating more uniform. At the same time, the heating hole 121 located at the center position of the base bottom wall 12 can also facilitate the arrangement of the second spiral groove 1221.

[0050] In further embodiments of the present application, asFigure 2 、 Figure 4 and Figure 6 In the first direction, the groove bottom wall of the second spiral groove 1221 is located between the inner end face and the outer end face of the base bottom wall 12, so that when the aerosol generating stick 400 is loaded into the heating cavity 13, the inner end face of the base bottom wall 12 abuts against the end face of the aerosol generating stick 400, and the second spiral groove 1221 is located below the aerosol generating stick 400 and is not blocked, so as to ensure smooth airflow and guide the airflow in the second spiral groove 1221 to move gradually towards the heating hole 121. In the first direction, the depth of the second spiral groove 1221 is the same, that is, the depth of different groove sections in the second spiral groove 1221 remains consistent, which is beneficial to the stability of airflow movement and also facilitates processing and manufacturing.

[0051] It should be noted that the depth of the second spiral groove 1221 specifically refers to the distance from the inner end face of the base bottom wall 12 to the groove bottom wall of the second spiral groove 1221 in the first direction. Of course, in actual application, the second spiral groove 1221 can also be provided in a structure form with different depths in different regions according to the needs of use, for example, in a specific example, the depth of the second spiral groove 1221 can be gradually reduced in the direction extending from the second spiral groove 1221 to the heating hole 121, so that the groove bottom wall of the second spiral groove 1221 forms a form with a certain slope, so as to guide the airflow and promote the airflow to move in the first direction towards the aerosol generating stick 400, so as to facilitate the entry into the inside of the aerosol generating stick 400.

[0052] Further, as shown in Figure 4 、 Figure 7 and Figure 8 The base body 1 has a communication port 123 in the base bottom wall 12, the first spiral groove 1121 on the base side wall 11 extends to the communication port 123 away from the insertion port 111, and one end of the second spiral groove 1221 on the inner end face of the base bottom wall 12 also extends to the communication port 123, and the first spiral groove 1121 and the second spiral groove 1221 are in communication through the communication port 123.

[0053] In further embodiments of the present application, as shown in the example in Figure 4 The cross-sectional area of the first spiral groove 1121 is in the range of 0.2mm 2 to 5mm 2 , so as to meet the air flow requirement while keeping a certain thickness of the base side wall to meet the strength design requirement.

[0054] Further, the first spiral groove 1121 can be provided as Figure 4The cross-sections are shown in the figure, that is, in the extension direction of the first spiral groove 1121, the cross-sectional area is the same, and is always consistent, so that the airflow movement remains stable.

[0055] Of course, in actual application, at least part of the groove section of the first spiral groove 1121 can also be provided in a structure form with different cross-sectional areas according to the use needs. For example, in a specific example, the first spiral groove 1121 can be provided in a structure form with gradually decreasing cross-sectional areas in the direction extending towards the base bottom wall 12, so that the airflow velocity increases, so that the airflow can quickly enter the second spiral groove 1221 from the first spiral groove 1121, and the spiral movement of the airflow in the second spiral groove 1221 is facilitated, so that the airflow is more easily introduced into the inside of the aerosol generating stick.

[0056] In further embodiments of the present application, as shown in Figure 5 , Figure 6 and Figure 9 , the heating base 100 further comprises a mounting sleeve 2. The mounting sleeve 2 has a mounting cavity 20 therein, and the base body 1 is arranged in the mounting cavity 20 and detachably connected with the mounting sleeve 2; in the first direction, the mounting cavity 20 has oppositely arranged first and second openings 21 and 22, the insertion opening 111 of the base body 1 is arranged corresponding to the first opening 21, and the heating cavity 13 of the base body 1 is in communication with the first opening 21 to allow the aerosol generating stick 400 to be inserted. When applied to the atomization device, as shown in Figure 10 , the mounting sleeve 2 can be connected and assembled with the shell 31 of the atomization device 300. As shown in Figure 6 , the shape of the first opening 21 is adapted to the aerosol generating stick 400, and the aperture of the first opening 21 is not less than a first threshold value, so as to reserve a sufficient opening size for the aerosol generating stick 400 to pass through; when the aerosol generating stick 400 passes through the first opening 21 and is inserted into the heating cavity 13 through the insertion opening 111 of the base body 1, there is a certain gap space between the inner edge of the first opening 21 and the base side wall 11 of the aerosol generating stick 400, so as to form an air inlet gap 23, and the external airflow can pass through the air inlet gap 23 to enter the first air channel 112 of the base body 1, so as to realize top air inlet. The first threshold value can be set according to the size of the aerosol generating stick.

[0057] Further, as shown in Figure 6 and Figure 9 , the base body 1 has a sealing protrusion 113 arranged in the circumferential direction on the outer side of the base side wall 11, and the sealing protrusion 113 abuts against the inner side wall of the mounting sleeve 2, so that the base body 1 and the mounting sleeve 2 are sealingly assembled, and the sealing protrusion 113 can support and limit the base body 1 in the lateral direction, so as to improve the assembly stability.

[0058] Further, as shown inFigures 1 to 3 and Figure 5 As shown in the figures, the base body 1 has a first clamping structure 114 on the outer side of the base side wall 11, and the inner side wall of the mounting sleeve 2 has a second clamping structure 24 matched with the first clamping structure 114, and the second clamping structure 24 is clamped with the corresponding first clamping structure 114 to achieve connection and fixation.

[0059] In a specific example, the first clamping structure 114 and the second clamping structure 24 can be a snap structure and a clamping groove structure as shown in Figure 6 , the snap structure is connected to the sealing protrusion 113 away from the insertion port 111, and a gap is maintained between the snap structure and the outer side wall of the base body 1, and the clamping groove structure is located on the inner side wall of the mounting sleeve 2; when the base body 1 is assembled into the mounting cavity 20 of the mounting sleeve 2 along the first direction, the snap structure can be elastically deformed under the extrusion of the inner side wall of the mounting sleeve 2, and when the snap structure moves to the position of the clamping groove structure, the snap structure resets and extends into the clamping groove structure to form a clamping fit.

[0060] It should be noted that in actual application, the snap structure and the clamping groove structure can also be interchanged, that is, the clamping groove structure is arranged on the outer side of the base side wall 11, and the snap structure is arranged on the inner side wall of the mounting sleeve 2, which can also achieve clamping fit, and the specific arrangement and clamping principle are similar to the above case, which will not be repeated here.

[0061] Further, as shown in the examples in Figure 6 and Figure 9 , the mounting sleeve 2 has a stepped groove 27 near one end of the first opening 21, and the first opening 21 is specifically located on the groove bottom wall of the stepped groove 27; the shape of the stepped groove 27 is matched with the shape of the end of the base body 1 provided with the insertion port 111, the end of the base body 1 provided with the insertion port 111 extends into the stepped groove 27, and the end face of the base body 1 abuts against the groove bottom wall of the stepped groove 27 to limit the base body 1 in the first direction, and cooperate with the first clamping structure 114 and the second clamping structure 24 to achieve connection and fixation between the base body 1 and the mounting sleeve 2.

[0062] In further embodiments of the present application, as shown in the examples in Figures 4 to 6 , the outer side wall of the mounting sleeve 2 has a third clamping structure 25, which can form a clamping fit with the shell when assembled in the atomization device. It should be noted that the third clamping structure 25 is not limited to the form of the clamping convex structure shown in the figures, and can be specifically arranged according to the specific matching structure of the shell.

[0063] In further embodiments of the present application, as shown in the examples in Figure 5 , Figure 6 andFigure 10 In the example, the outer side wall of the mounting sleeve 2 has a boss structure 26 near the first opening 21. When assembled with the housing 31 of the atomizing device 300, the boss structure 26 abuts against the housing 31 so that the mounting sleeve 2 is partially inserted into the housing 31, while the part of the mounting sleeve 2 with the first opening 21 is located outside the housing 31 for easy disassembly.

[0064] An embodiment of the second aspect of this application provides an atomizing device 300, such as Figure 10 , Figure 11 As shown, the atomizing device 300 includes a housing 31, a heating base 100 as described in any of the embodiments of the first aspect, and a heating assembly 32. The housing 31 serves as the base of the atomizing device 300. In a first direction, one end of the housing 31 has an assembly groove 311 for assembling the heating base 100. The heating base 100 is partially disposed in the assembly groove 311 and detachably connected to the housing 31. The insertion port 111 of the heating base 100 corresponds to the opening of the assembly groove 311 for inserting the aerosol generating rod 400. The heating assembly 32 is disposed within the housing 31 and corresponds to the base bottom wall 12 of the base body 1 in the first direction. The heating assembly 32 has a heating element 321 disposed along the first direction towards the base body 1, and the heating element 321 extends through a heating hole 121 on the base bottom wall 12 into a heating chamber 13, so that when the heating chamber 13 contains the aerosol generating rod 400, the heating element 321 heats the aerosol generating rod 400. The size of the heating hole 121 is larger than the size of the heating element 321, so that air intake space can still be reserved when the heating element 321 is inserted into the heating hole 121.

[0065] like Figure 11 In the example, during use, the aerosol generating rod 400 is inserted into the heating chamber 13, allowing the heating element 321 to penetrate the interior of the aerosol generating rod 400, thereby heating the atomizing matrix inside the aerosol generating rod 400 to form an aerosol. At this time, the first air passage 112 of the base body 1 is connected to the outside. When the user performs a suction action through the suction end of the aerosol generating rod 400 (the end located outside the heating chamber 13), external air enters the first air passage 112 under negative pressure, then spirals along the first air passage 112 to the inner end face of the base bottom wall 12 and enters the second air passage 122. Simultaneously, it is heated to form a hot airflow, which then flows through the second air passage 122 to the heating hole 121, and enters its interior from the end face of the aerosol generating rod 400 under negative pressure, carrying the aerosol generated by the atomizing matrix to the suction end of the aerosol generating rod 400.

[0066] By the atomization device 300 in the embodiment, top air inlet can be achieved in the state that the aerosol generating stick 400 is inserted into the heating cavity 13, air flow is supplied through the first air channel 112 and the second air channel 122 of the heating base 100, the air flow is formed into spiral motion and heated to form hot air flow, and then flows into the aerosol generating stick 400 from the heating hole 121, so as to avoid cold air directly entering the aerosol generating stick 400 to cause cold-hot confrontation, which is beneficial to enhancing the heating effect; and the spiral air flow formed can effectively reduce the resistance in the motion process, the air flow power is stronger, and the user does not need large suction force when performing the suction action, which is beneficial to improving the use experience. In addition, no air channel needs to be additionally arranged in the shell 31 of the atomization device 300, which is beneficial to the structural design of the whole machine.

[0067] A specific example of the atomization device 300 of the present application will be further described below in combination with the drawings.

[0068] As shown in Figure 10 and Figure 11 , the heating base 100 of the atomization device 300 includes a base body 1 and a mounting sleeve 2. As shown in Figures 1 to 9As shown, the base body 1 is a cylindrical structure, has a base side wall 11 and a base bottom wall 12, and has a cylindrical heating cavity 13 formed by the base side wall 11 and the base bottom wall 12 in the base body 1; in the first direction, one end of the base body 1 opposite to the base bottom wall 12 has an insertion opening 111, and the insertion opening 111 is in communication with the heating cavity 13. The base bottom wall 12 is provided with a heating hole 121 in communication with the heating cavity 13, and the heating hole 121 is located at the center of the base bottom wall 12 and is coaxially arranged with the heating cavity 13. The inner side of the base side wall 11 has a first air channel 112, which specifically includes a first spiral groove 1121 arranged in a spiral manner, one end of the first air channel 112 penetrates through the end face of the base side wall 11 and is in communication with the insertion opening 111, and the other end of the first air channel 112 extends to the inner end face of the base bottom wall 12; the inner end face of the base bottom wall 12 is correspondingly provided with a second air channel 122, which specifically includes a second spiral groove 1221 arranged in a spiral manner, and the rotation direction of the second spiral groove 1221 is the same as that of the first spiral groove 1121. The base bottom wall 12 has a communication port 123 at the connection position of the first spiral groove; the second spiral groove 1221 specifically has a state of gradually shrinking to the center position from the outside to the inside, one end of the second spiral groove 1221 extends to the communication port 123, and the second spiral groove 1221 is in communication with the first spiral groove 1121 through the communication port 123, and the other end of the second spiral groove 1221 extends to the side edge of the heating hole 121 and is in communication with the heating hole 121; in the first direction, the groove bottom wall of the second spiral groove 1221 is located between the outer end face and the inner end face of the base bottom wall 12, and the depth is consistent. The base body 1 is made of PEEK (Poly ether-ether-ketone, polyether ether ketone) or PI (Polyimide, polyimide) material, such as Figure 7 As an example in the specification, the cross sections of the first spiral groove 1121 and the second spiral groove 1221 are rectangular structures, and the cross-sectional area of the first spiral groove 1121 is in the range of 0.2mm 2 to 5mm 2 .

[0069] As Figure 5 , Figure 6 and Figure 9In the example, the mounting sleeve 2 has a mounting cavity 20, and the base body 1 is disposed within the mounting cavity 20. In a first direction, the mounting cavity 20 has a first opening 21 and a second opening 22 disposed opposite to each other. The insertion port 111 of the base body 1 is correspondingly disposed with respect to the first opening 21, and the heating cavity 13 of the base body 1 communicates with the first opening 21 for the insertion of the aerosol generating rod 400. The mounting sleeve 2 has a stepped groove 27 at one end near the first opening 21, and the first opening 21 is specifically located on the bottom wall of the stepped groove 27. One end of the base body 1 with the insertion port 111 extends into the stepped groove 27, and the end face of the base body 1 abuts against the bottom wall of the stepped groove 27. Wherein, as... Figure 5 In the example, the shape of the first opening 21 is adapted to the aerosol generating rod 400, and the aperture of the first opening 21 is not less than the first threshold, so as to reserve sufficient opening size for the aerosol generating rod 400 to pass through.

[0070] like Figure 6 In the example, the outer surface of the base sidewall 11 has a circumferentially arranged sealing protrusion 113, which abuts against the inner sidewall of the mounting sleeve 2 to form a sealed assembly between the base body 1 and the mounting sleeve 2. The outer surface of the sealing protrusion 113 has two first snap-fit ​​structures 114, symmetrically arranged on both sides of the sealing protrusion 113. Correspondingly, the inner sidewall of the mounting sleeve 2 has two second snap-fit ​​structures 24, which engage with the corresponding first snap-fit ​​structures 114 to achieve a fixed connection. Specifically, the first snap-fit ​​structure 114 adopts a spring-loaded structure, and the second snap-fit ​​structure 24 adopts a slot structure.

[0071] like Figure 10 and Figure 11As an example in the embodiment, on the shell 31, a step structure 314 is arranged at the opening edge of the assembly groove 311, and two boss structures 26 are correspondingly arranged on the outer side wall of the mounting sleeve 2. When the mounting sleeve 2 is arranged to be inserted into the assembly groove 311 at the end of the second opening 22, the boss structure 26 extends into the step structure 314 and abuts against the step structure 314 in the first direction, so that the end of the mounting sleeve 2 provided with the first opening 21 is located outside the assembly groove 311. The outer side wall of the part of the mounting sleeve 2 inserted into the assembly groove 311 has two third clamping structures 25, and the two third clamping structures 25 are symmetrically arranged on both sides of the mounting sleeve 2. Correspondingly, the inner side wall of the assembly groove 311 of the shell 31 is correspondingly provided with two fourth clamping structures 312, and the fourth clamping structures 312 and the corresponding third clamping structures 25 form a mutual clamping fit, so that the mounting sleeve 2 and the assembly groove 311 form a detachable connection. Specifically, the third clamping structure 25 and the fourth clamping structure 312 adopt a clamping convex structure that mutually fits. When the mounting sleeve 2 is inserted into the assembly groove 311 in the first direction, a slight elastic deformation is generated between the corresponding clamping convex structures by mutual extrusion, so as to form a clamping fit. At the same time, the abutting fit of the boss structure 26 and the step structure 314 in the first direction plays a limiting role, so as to realize assembly and fixation.

[0072] As an example in the embodiment, Figure 11 The heating assembly 32 includes a heating piece 321, a conductive structure 322, and a power supply device 323 and an electric control element (not shown in the figure). The shell 31 is provided with a support structure 33 corresponding to the heating base 100. The heating piece 321 is arranged on the support structure 33. The heating piece 321 specifically adopts a cylindrical structure and extends towards the heating base 100 and extends into the heating cavity 13 through the heating hole 121. The end of the heating piece 321 inserted into the heating cavity 13 has a spike part, so as to facilitate penetration into the inside of the aerosol generating stick 400. The conductive structure 322 is connected with the heating piece 321, and the conductive structure 322 is electrically connected with the power supply device 323, so that the power supply device 323 is electrically connected with the heating piece 321, so as to supply power to the heating piece 321, so that the heating piece 321 can be electrified to heat. The electric control element is electrically connected with the power supply device 323 and is used for corresponding control operation of power supply.

[0073] As an example in the embodiment, Figure 5 , Figure 6 and Figure 11In the example shown in the figure, when the aerosol generating stick 400 is inserted into the heating cavity 13, the heating member 321 penetrates into the inside of the aerosol generating stick 400 to heat the atomized substrate inside the aerosol generating stick 400 to form aerosol. When the user performs a suction action through the suction end of the aerosol generating stick 400 (the end located outside the heating cavity 13), external air enters the first spiral groove 1121 through the air inlet gap 23 under the action of negative pressure, and then spirally moves along the first spiral groove 1121 to the inner end face of the base bottom wall 12, and then flows to the heating hole 121 through the second spiral groove 1221. The airflow is heated to form a hot airflow during movement in the base body, and the hot airflow enters the inside of the aerosol generating stick 400 from the end face of the aerosol generating stick 400 under the action of negative pressure to carry the aerosol generated by the atomized substrate to the suction end of the aerosol generating stick 400.

[0074] After use, the mounting sleeve 2 and the base body 1 can be taken out of the assembly groove 311 together to facilitate replacement of the aerosol generating stick 400 and facilitate removal of residues generated during heating.

[0075] The atomization device 300 in the present application also has all the beneficial effects of the heating base 100 in any of the above embodiments, which will not be repeated here.
