[0032] ​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 exchanged or adjusted in a manner 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.

[0033] The serial numbers of the components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. Unless otherwise specified, "connection" and "coupling" in this application include direct and indirect connections (couplings).

[0034] 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 generate aerosol with different tastes after atomization to meet different user needs.

[0035] The heating base assembly provided by the present application can be applied to an atomizing equipment (such as a heat-not-burn equipment) to heat and atomize the aerosol generating stick. A first air channel extending spirally and communicating with the insertion port is arranged in the heating base, a corresponding second air channel is arranged on the outer end face of the base bottom wall of the heating base, and the second air channel communicates with the first air channel and the heating hole on the base bottom wall. Correspondingly, the air inlet hole is arranged on the side wall of the mounting shell, and the side air channel communicating with the first air channel is arranged in the mounting shell, so that when the aerosol generating stick is loaded into the heating cavity in the heating base, the airflow entering the mounting shell through the air inlet hole can enter the first air channel of the heating base through the side air channel, and then move to the outer end face of the base bottom wall along the first air channel, and then move to the heating hole through the second air channel and flow back into the heating cavity. When applied to the atomizing equipment, the heating member of the atomizing equipment is inserted into the heating cavity through the heating hole on the cavity bottom wall of the heating cavity, and the aerosol generating stick loaded into the heating cavity is heated and atomized. The airflow is heated to form a hot airflow during movement along the first air channel, the hot airflow passes through the heating hole and flows into the interior of the aerosol generating stick from the end face of the aerosol generating stick, so as to avoid the direct entry of cold air with lower temperature into the aerosol generating stick to cause cold and hot confrontation, which is beneficial to enhancing the heating effect. Moreover, the airflow spirally moves in the heating cavity, which can effectively reduce the resistance of the airflow during movement, 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.

[0036] Some embodiments of the heating base assembly and the atomizing equipment provided by the present application will be described below in combination with the drawings.

[0037] In the embodiments of the first aspect of the present application, a heating base assembly 100 is provided, as shown in Figure 1 , Figure 2 ,Figure 3 and Figure 4 As shown, the heating base assembly 100 includes a heating base 1 and a mounting shell 2. The heating base 1 has a base side wall 11 and a base bottom wall 12, and the heating base 1 has a heating cavity 13 formed by the base side wall 11 and the base bottom wall 12. In a first direction, the heating base 1 has an insertion port 111 at one end opposite to the base bottom wall 12. The insertion port 111 communicates with the heating cavity 13 and is used to insert 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, which is used for 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 of the first air passage 112 passes through the base bottom wall 12 and extends to the outer end face of the base bottom wall 12. A second air passage 122 is correspondingly arranged on the outer 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 from 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 heating hole 121. The mounting shell 2 has a mounting cavity 20, and the heating base 1 is disposed in the mounting cavity 20 and detachably connected to the mounting shell 2. In the first direction, the mounting cavity 20 has a first opening 21 and a second opening 22 that are arranged opposite to each other. The insertion port 111 of the heating base 1 is correspondingly arranged with the first opening 21, and the heating chamber 13 of the heating base 1 is connected with the first opening 21. In the first direction, a side air passage 271 is provided at the inner edge of the first opening 21. The side air passage 271 communicates with the first air passage 112 at one end of the heating base 1 where the insertion port 111 is provided. The side wall of the mounting shell 2 has a through air inlet 23, and in the lateral direction, an air inlet gap 28 is formed between the heating base 1 and the mounting shell 2. When applied to an atomizing device, the mounting shell 2 can be connected and assembled with the shell of the atomizing device.

[0038] like Figure 1 and Figure 2 As shown, with the aerosol generating rod 400 inserted into the heating chamber 13, external airflow can still enter the mounting chamber 20 through the air inlet 23 of the mounting shell 2, and then enter the first air passage 112 of the heating base 1 through the side air passage 271. When the user performs a suction action on the aerosol generating rod 400, the airflow spirals along the first air passage 112 under negative pressure, and is heated to form a hot airflow; when the airflow reaches the outer end face of the base bottom wall 12, it flows along the second air passage 122 to the heating hole 121, and then flows back into the heating chamber 13 through the heating hole 121, and is drawn into the interior of the aerosol generating rod 400 from the end face of the aerosol generating rod 400.

[0039] It can be understood that the aerosol generating stick needs to be heated during use so that the atomized substrate therein is heated and atomized to generate aerosol. 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 aerosol generated by atomization needs to be carried to the suction end by the airflow generated by the suction action. Therefore, if the temperature of the inlet airflow (for example, cold air) is low, the cold and hot collision effect will be generated on the atomized substrate after entering the aerosol generating stick, that is, the temperature of the atomized substrate is reduced, thereby affecting the atomization effect.

[0040] The heating base assembly 100 in the embodiment can make the airflow enter the first air duct 112 spirally arranged in the heating base 1 through the air inlet hole 23 and the side air duct 271 of the mounting shell 2 when the aerosol generating stick 400 is assembled in the heating cavity 13, and the airflow can move along the first air duct 112 to the outer end face of the base bottom wall 12, and form a hot airflow by being heated. Then, the hot airflow moves to the heating hole 121 through the second air duct 122 of the base bottom wall 12 and is sucked into the inside of the aerosol generating stick 400, thereby avoiding the cold and hot collision caused by the direct entry of cold air into the inside of the aerosol generating stick, and being beneficial to enhancing the heating effect. Moreover, the spiral airflow formed can effectively reduce the resistance in the movement process, and the airflow force is stronger. When the user performs the suction action, a large suction force is not needed, which is beneficial to improving the use experience.

[0041] In addition, since the air is not needed to be inhaled through the first opening of the mounting shell, the size of the first opening can be set to be matched with the aerosol generating stick, so that the inside edge of the first opening can abut against the aerosol generating stick when the aerosol generating stick is inserted through the first opening to the heating cavity, so that the aerosol generating stick is kept stable and is prevented from falling off. Moreover, since the heating base assembly has a complete air inlet air duct, when applied to the atomization device, the air duct does not need to be arranged inside the shell of the atomization device, which is beneficial to the structural design of the whole machine.

[0042] It should be noted that the number of the first air duct 112, the second air duct 122, the air inlet hole 23 and the side air duct 271 in the embodiment can be one or more, and the rotation direction of the first air duct 112 can be selected according to the actual situation, and is not limited to the clockwise direction shown in the drawings of the embodiment.

[0043] In further embodiments of the present application, as Figure 2 and Figure 3In the example shown in FIG. 1, one end of the mounting shell 2 close to the first opening 21 has a stepped groove 27, 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 one end of the heating base 1 provided with the insertion port 111, one end of the heating base 1 provided with the insertion port 111 extends into the stepped groove 27 and abuts with the inner side wall of the stepped groove 27 in the circumferential direction, and the end face of the heating base 1 abuts with the groove bottom wall of the stepped groove 27 to limit the heating base 1 in the first direction. Wherein, the side air channel 271 is located on the inner wall surface of the stepped groove 27, as shown in Figure 2 In the example shown in FIG. 1, the side air channel 271 extends from the side wall of the stepped groove 27 to the groove bottom wall and communicates with the first air channel 112 on the end face of the heating base 1, so that the first air channel 112 communicates with the air inlet hole 23 through the side air channel 271, and the external gas entering the mounting cavity 20 through the air inlet hole 23 can enter the first air channel 112 of the heating base 1 through the side air channel 271. By setting the stepped groove 27, the mounting shell 2 and the heating base 1 can be inserted and assembled, and the heating base 1 is limited to facilitate the assembly and fixation of the heating base assembly 100 and the shell of the atomization device.

[0044] Further, as shown in Figure 2 to Figure 6 , on the heating base 1, the outer side face of the base side wall 11 has a sealing protrusion 113 arranged in the circumferential direction, the sealing protrusion 113 abuts with the inner side wall of the mounting shell 2 to form a sealed assembly between the heating base 1 and the mounting shell 2, and can support and limit in the lateral direction to improve the assembly stability. Wherein, in the first direction, the air inlet hole 23 is correspondingly arranged between the sealing protrusion 113 and the stepped groove 27, and after the airflow enters the air inlet gap 28 between the mounting shell 2 and the heating base 1 through the air inlet hole, the airflow can be prevented from flowing to the second opening 22 direction through the sealing protrusion 113, and the airflow can only enter the first air channel 112 of the heating base 1 through the side air channel 27 to prevent air leakage.

[0045] Wherein, as shown in Figure 2 , Figure 3 , on the heating base 1, the outer side face of the sealing protrusion 113 has a first clamping structure 114, and correspondingly, the inner side wall of the mounting shell 2 has a second clamping structure 24 matched with the first clamping structure 114, the second clamping structure 24 and the corresponding first clamping structure 114 form a clamping fit to realize connection and fixation.

[0046] In a specific example, the first clamping structure 114 and the second clamping structure 24 can be specifically as shown in Figure 2The elastic buckle structure is connected to the sealing protrusion 113 away from the insertion port 111, and a gap is maintained between the elastic buckle structure and the outer side wall of the heating base 1. The clamping groove structure is located on the inner side wall of the mounting shell 2. When the heating base 1 is mounted into the mounting cavity 20 of the mounting shell 2 along the first direction, the elastic buckle structure can be elastically deformed under the extrusion of the inner side wall of the mounting shell 2, and when the elastic buckle structure moves to the position opposite to the clamping groove structure, the elastic buckle structure resets and extends into the clamping groove structure to form a clamping connection.

[0047] It should be noted that in actual application, the elastic buckle structure and the clamping groove structure can also be interchanged, that is, the clamping groove structure is arranged on the outer side wall of the sealing protrusion 113, and the elastic buckle structure is arranged on the inner side wall of the mounting shell 2, which can also achieve the clamping connection. The specific arrangement mode and clamping principle are similar to the above case, and will not be described here.

[0048] In further embodiments of the present application, as shown in Figure 5 、 Figure 6 、 Figure 7 and Figure 8 , the first air channel 112 specifically includes a first spiral groove 1121, which penetrates the inner side of the base side wall 11 in the lateral direction, that is, the first spiral groove 1121 is formed by the inner side of the base side wall 11 being recessed, and the opening side of the first spiral groove 1121 faces the inside of the heating base 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 face of the base side wall 11 at the insertion port 111, and the other end of the first spiral groove 1121 extends to the outer end face of the base bottom wall 12 and communicates with the second air channel 122. When the aerosol generating stick 400 is mounted into the heating cavity 13, as shown in Figure 2 , the side wall of the aerosol generating stick 400 abuts against or maintains a small gap with the inner side 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 face of the base side wall 11 and move along the spiral air channel to the outer end face of the base bottom wall 12, forming a spiral airflow. Compared with the disordered movement state, the airflow has stronger power, which can reduce the resistance in the movement process and make the airflow movement more stable and smooth.

[0049] In actual application, the cross-sectional shape of the first spiral groove 1121 can be rectangular, semicircular, triangular, etc., and of course, other shapes suitable for airflow passing can also be set according to needs. For example, as shown in Figure 7 , the cross-sectional area of the first spiral groove 1121 is 0.2mm 2 to 5mm 2The number of turns and the pitch of the first spiral groove 1121 can be set according to the size of the heating base 1 in the first direction, 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.

[0050] 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 heating base 1 in the first direction. When the pitch of the first spiral groove 1121 is relatively large, a plurality of first spiral grooves 1121 can be provided as needed to further increase the air intake. The plurality of first spiral grooves 1121 are different in phase in the circumferential direction, i.e. in the first direction, and are kept at a certain interval to prevent interference. Taking two first spiral grooves 1121 as an example, the two first spiral grooves 1121 are different in phase by 180° in the circumferential direction, and in the first direction, the adjacent turns of one of the first spiral grooves 1121 are provided with the other first spiral groove 1121.

[0051] It should be noted that the above is only one preferred example of the first air passage 112, and the first air passage 112 is not limited to the form of the first spiral groove 1121 described above. For example, the first air passage 112 can also be provided in the form of a closed hole structure. In another specific example, the first air passage 112 can be in the form of a first spiral hole, which is located inside the base side wall 11, i.e. without openings on both the inner and outer sides in the lateral direction. The first spiral hole is spirally arranged in 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 outer end face of the base bottom wall 12 and communicates with the second air passage 122. The first spiral hole forms a spiral air passage, and the external gas can enter the first spiral hole at the end face of the base side wall 11 and move spirally along the first spiral hole to the outer end face of the base bottom wall 12, forming a spiral air flow. By providing the first spiral hole, the air flow intensity can also be increased, and the resistance during air flow movement can be further reduced, improving the stability of air flow movement.

[0052] In further embodiments of the present application, as Figure 2 , Figure 3 and Figure 6As shown, on the outer end surface 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 flow in a spiral motion state on the outer end surface 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 conducive to making the airflow flow smoothly and smoothly to the heating hole 121.

[0053] In actual application, when multiple first air channels 112 are provided, multiple second spiral grooves 1221 can also be provided accordingly, 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 rectangular, semicircular, triangular, etc., and the width of the second spiral groove 1221 can be set according to the spatial position on the base bottom wall 12, such as the example in Figure 9 , 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 in a gradual state to keep the airflow motion stable.

[0054] Further, as an example in Figure 2 , Figure 3 , Figure 8 , the second spiral groove 1221 gradually extends in the first direction to the direction close to the inner end surface of the base bottom wall 12, wherein the end of the second spiral groove 1221 in communication with the heating hole 121 is located between the inner end surface and the outer end surface of the base bottom wall 12 in the first direction, so as to guide the airflow in the second spiral groove 1221, and make the airflow gradually move to the direction close to the heating cavity 13, so as to promote the air inlet at the heating hole 121.

[0055] Further, as an example in Figure 2 , Figure 4 and Figure 8In the example shown in FIG. 1, the heating cavity 13 adopts a cylindrical cavity to match the shape of the aerosol generating stick. Correspondingly, the heating hole 121 is located at the center of the base bottom wall 12 and is coaxially arranged with the heating cavity 13 to correspond to the central area of the end face of the aerosol generating stick. After the heating member extends into the heating cavity 13 from the heating hole 121, the heating member can penetrate into the aerosol generating stick to a position close to the center, so that the heating is more uniform. At the same time, the location of the heating hole 121 at the center of the base bottom wall 12 can facilitate the arrangement of the second spiral groove 1221.

[0056] In further embodiments of the present application, as shown in Figure 3 、 Figure 6 、 Figure 8 the base bottom wall 12 of the heating base 1 has a communication port 123. The first air channel 112 on the base side wall 11 extends to the communication port 123 away from the insertion port 111. The first air channel 112 and the second air channel 122 on the outer end face of the base bottom wall 12 both extend to the communication port 123. The first air channel 112 and the second air channel 122 are in communication through the communication port 123, so that the airflow in the first air channel 112 can flow into the second air channel 122 on the outer end face of the base bottom wall 12 through the communication port 123. In the projection plane perpendicular to the first direction, the communication port 123 is located outside the projection plane of the insertion port 111, i.e., the communication port 123 is located close to the outer edge of the base bottom wall 12 to correspond to the base side wall 11. The first air channel 112 extends along the base side wall 11 to the connection between the base side wall 11 and the base bottom wall 12 to communicate with the communication port 123 without changing the extension direction. Correspondingly, the location of the communication port 123 close to the outer edge of the base bottom wall 12 can reserve more space for the second air channel 122 to meet the requirements of airflow transition.

[0057] In further embodiments of the present application, as shown in Figure 1 to Figure 3 the outer side wall of the mounting shell 2 has a third clamping structure 25 to form a clamping fixation with the shell of the atomization device when assembled in the shell. It should be noted that the third clamping structure 25 is not limited to the form of the clamping convex structure shown in the figure, and can be specifically arranged according to the specific matching structure of the shell.

[0058] In further embodiments of the present application, as shown in Figure 1 to Figure 3 the outer side wall of the mounting shell 2 has a boss structure 26 close to the first opening 21, and the air inlet hole 23 penetrates the boss structure 26 in the lateral direction. When assembled with the shell of the atomization device, the boss structure 26 abuts against the shell to enable the mounting shell 2 to be partially inserted into the shell, and the part of the mounting shell 2 where the first opening 21 is arranged is located outside the shell to facilitate disassembly.

[0059] In the embodiments of the second aspect of the present application, an atomization device 300 is provided, as shown inFigure 9 、 Figure 10 As shown in FIG. 1, the atomization device 300 comprises a housing 31, the heating base assembly 100 in any of the embodiments of the first aspect, and a heating assembly 32. The housing 31 serves as the base of the atomization device 300. In the first direction, one end of the housing 31 is provided with a fitting groove 311 for fitting the heating base assembly 100. At least part of the heating base assembly 100 is arranged in the fitting groove 311 and detachably connected with the housing 31, and the air inlet hole 23 on the mounting shell 2 is in communication with the external atmosphere. The heating assembly 32 is arranged in the housing 31 and corresponds to the base bottom wall 12 of the heating base 1 in the first direction. The heating assembly 32 has a heating element 321 arranged towards the heating base 1 in the first direction, and the heating element 321 extends into the heating cavity 13 through the heating hole 121 on the base bottom wall 12, so as to heat the aerosol generating stick 400 when the aerosol generating stick 400 is contained in the heating cavity 13. The size of the heating hole 121 is greater than the size of the heating element 321, so that the air inlet space can be reserved when the heating element 321 extends into the heating hole 121.

[0060] As Figure 2 and Figure 10 In use, the aerosol generating stick 400 is inserted into the heating cavity 13, and the heating element 321 extends into the interior of the aerosol generating stick 400 to heat the atomization substrate in the interior of the aerosol generating stick 400 to form aerosol. When the user performs a suction action through the suction end (the end outside the heating cavity 13) of the aerosol generating stick 400, the external air enters the air inlet gap 28 between the mounting shell 2 and the heating base 1 through the air inlet hole 23 under the action of negative pressure, and then enters the first air channel 112 through the side air channel 271, and then spirally moves along the first air channel 112 to the outer end face of the base bottom wall 12, and is heated to form a hot air flow, and then the hot air flow flows to the heating hole 121 through the second air channel 122, and then flows back into the heating cavity 13 through the heating hole 121. The hot air flow enters the interior of the aerosol generating stick 400 through the end face of the aerosol generating stick 400 under the action of negative pressure, so as to carry the aerosol generated by the atomization substrate to the suction end of the aerosol generating stick 400.

[0061] By the atomization device 300 in the embodiment, in the state that the aerosol generating stick 400 is inserted into the heating cavity 13, side air inlet is achieved by the air inlet hole 23 of the mounting shell 2 in the heating base assembly 100, and air flow passes through the side air channel 271, the first air channel 112 and the second air channel 122, so that the air flow forms a spiral motion and is heated to form a hot air flow, and then flows into the inside of the aerosol generating stick 400 through the heating hole 121, so as to avoid cold air directly entering the inside of the aerosol generating stick 400 to cause cold-hot confrontation, which is beneficial to enhancing the heating effect; moreover, the spiral air flow formed can effectively reduce the resistance in the motion process, and the air flow power is stronger, so that the user does not need to exert a large suction force when performing a suction action, which is beneficial to improving the use experience; the air channel does not need to be additionally arranged in the shell 31 of the atomization device 300, which is beneficial to the structural design of the whole machine. In addition, since the side air inlet mode is adopted, the size of the first opening 21 of the mounting shell 2 can be set to be matched with the aerosol generating stick 400, so that after the aerosol generating stick 400 is inserted into the heating cavity 13, the outer side wall of the aerosol generating stick 400 can abut against the inner side edge of the first opening 21, so as to use the friction force to limit the aerosol generating stick 400, thereby preventing the aerosol generating stick 400 from falling off.

[0062] The atomization device 300 of the present application will be further introduced in combination with the drawings.

[0063] As shown in Figure 9 and Figure 10 , the heating base assembly 100 of the atomization device 300 specifically includes the heating base 1 and the mounting shell 2. As shown in Figure 1 to Figure 8As shown, the heating base 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 heating base 1, the size of the heating cavity 13 is matched with the aerosol generating stick 400; in the first direction, the end of the heating base 1 opposite to the base bottom wall 12 has an insertion port 111, the insertion port 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, 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. Wherein, the inner side of the base side wall 11 has a first air channel 112, the first air channel 112 specifically includes a first spiral groove 1121 arranged in a spiral, one end of the first air channel 112 penetrates the end face of the base side wall 11 and is in communication with the insertion port 111, the other end of the first air channel 112 penetrates the base bottom wall 12; the outer end face of the base bottom wall 12 is correspondingly provided with a second air channel 122, the second air channel 122 specifically includes a second spiral groove 1221 arranged in a spiral, and the rotation direction of the second spiral groove 1221 is the same as that of the first spiral groove 1121; the second spiral groove 1221 specifically presents a state of gradually shrinking to the center position from the outside to the inside, the other end of the second spiral groove 1221 is in communication with the heating hole 121, and in the first direction, the communication position of the second spiral groove 1221 and the heating hole 121 is located between the outer end face and the inner end face of the base bottom wall 12. The base bottom wall 12 has a communication port 123, in the projection plane perpendicular to the first direction, the communication port 123 is located outside the projection plane of the insertion port 111, one end of the first spiral groove 1121 away from the insertion port 111 extends to the communication port 123, and one end of the second spiral groove 1221 also extends to the communication port 123 and forms communication with the first spiral groove 1121 through the communication port 123.

[0064] Wherein, the heating base 1 is made of PEEK (Poly ether-ether-ketone) or PI (Polyimide), such as Figure 7 As an example in the above, the cross sections of the first spiral groove 1121 and the second spiral groove 1221 are rectangular structures, the cross-sectional area of the first spiral groove 1121 is in the range of 0.2mm 2 to 5mm 2 .

[0065] As Figure 1 to Figure 3In the example shown in FIG. 1, the mounting shell 2 has a mounting cavity 20 therein, and the heating base 1 is arranged in the mounting cavity 20. In the first direction, the mounting cavity 20 has a first opening 21 and a second opening 22 arranged oppositely, the insertion opening 111 of the heating base 1 is arranged correspondingly to the first opening 21, and the heating cavity 13 of the heating base 1 is in communication with the first opening 21. The mounting shell 2 has a stepped groove 27 at one end close to the first opening 21, and the first opening 21 is specifically located on the groove bottom wall of the stepped groove 27. The end of the heating base 1 arranged with the insertion opening 111 extends into the stepped groove 27, and the end surface of the heating base 1 abuts against the groove bottom wall of the stepped groove 27. Among them, the stepped groove 27 has a side air channel 271 on the inner wall surface, which is in communication with the first air channel 112 on the end surface of the heating base 1. Figure 2 In the example shown in FIG. 1, the side air channel 271 extends from the side wall of the stepped groove 27 to the groove bottom wall and is in communication with the first air channel 112 on the end surface of the heating base 1. The shape of the first opening 21 is matched with the aerosol generating stick 400, and when the aerosol generating stick 400 is inserted into the heating cavity 13 through the first opening 21, the outer side wall of the aerosol generating stick 400 abuts against the inner side edge of the first opening 21 to limit the aerosol generating stick 400 by using the friction force.

[0066] As shown in FIG. 1, the base side wall 11 has a sealing protrusion 113 arranged circumferentially on the outer side surface, which abuts against the inner side wall of the mounting shell 2 to form a sealed assembly between the heating base 1 and the mounting shell 2. Figure 2 The outer side surface of the sealing protrusion 113 has two first clamping structures 114 symmetrically arranged on both sides of the sealing protrusion 113, and the inner side wall of the mounting shell 2 correspondingly has two second clamping structures 24 arranged correspondingly, which form clamping cooperation with the corresponding first clamping structures 114 to realize connection and fixation. Among them, the first clamping structure 114 is specifically a snap structure, and the second clamping structure 24 is specifically a clamping groove structure. The side wall of the mounting shell 2 has an air inlet hole 23 penetrating in the lateral direction, and the air inlet hole 23 is located between the sealing protrusion 113 and the stepped groove 27. An air inlet gap 28 corresponding to the air inlet hole 23 is formed between the mounting shell 2 and the heating base 1, so that the side air channel 271 is in communication with the air inlet hole 23 through the air inlet gap 28.

[0067] As shown in FIG. 1, the base side wall 11 has a sealing protrusion 113 arranged circumferentially on the outer side surface, which abuts against the inner side wall of the mounting shell 2 to form a sealed assembly between the heating base 1 and the mounting shell 2. Figure 2 , Figure 9 and Figure 10In the example, a mounting groove 311 is provided at the top of the housing 31, and a stepped structure 314 is provided at the opening edge of the mounting groove 311. Two boss structures 26 are correspondingly provided on the outer side wall of the mounting housing 2. When the end of the mounting housing 2 with the second opening 22 is inserted into the mounting groove 311, the boss structure 26 extends into the stepped structure 314 and abuts against the stepped structure 314 in the first direction, so that the end of the mounting housing 2 with the first opening 21 is located outside the mounting groove 311. The air inlet 23 penetrates the boss structure 26 laterally, and the side wall of the stepped structure 314 is provided with a stepped air passage 3141 opposite to the air inlet 23, so that the external airflow can smoothly enter the air inlet 23. The outer wall of the portion of the mounting shell 2 that extends into the assembly groove 311 has two third snap-fit ​​structures 25, which are symmetrically arranged on both sides of the mounting shell 2. Correspondingly, the inner wall of the assembly groove 311 of the shell 31 has two fourth snap-fit ​​structures 312. The fourth snap-fit ​​structures 312 and the corresponding third snap-fit ​​structures 25 form a snap-fit ​​engagement, thereby forming a detachable connection between the mounting shell 2 and the assembly groove 311. Specifically, the third snap-fit ​​structures 25 and the fourth snap-fit ​​structures 312 adopt a mutually cooperating snap-fit ​​protrusion structure. When the mounting shell 2 is inserted into the assembly groove 311 along the first direction, the mutual compression between the corresponding snap-fit ​​protrusion structures generates a slight elastic deformation to form a snap-fit ​​engagement. At the same time, the abutment engagement between the boss structure 26 and the step structure 314 in the first direction plays a limiting role, thereby achieving assembly fixation.

[0068] like Figure 10 In the example shown, the heating assembly 32 includes a heating element 321, a conductive structure 322, a power supply device 323, and an electronic control element (not shown in the figure). A support structure 33 corresponding to the heating base assembly 100 is provided inside the housing 31. The heating element 321 is mounted on the support structure 33. Specifically, the heating element 321 has a cylindrical structure, extends towards the heating base assembly 100, and extends into the heating cavity 13 through the heating hole 121. One end of the heating element 321 extending into the heating cavity 13 has a spike to facilitate penetration into the aerosol generating rod 400. The conductive structure 322 is connected to the heating element 321 and electrically connected to the power supply device 323, so that the power supply device 323 is electrically connected to the heating element 321 to supply power to the heating element 321, enabling the heating element 321 to generate heat. The electronic control element is electrically connected to the power supply device 323 and is used to perform corresponding control operations on the power supply.

[0069] like Figure 2 to Figure 4 and Figure 10In 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 hole 23 under the action of negative pressure, and then spirally moves along the first spiral groove 1121 to the outer end face of the base bottom wall 12, and is heated to form a hot air flow, and then the hot air flow flows to the heating hole 121 through the second spiral groove 1221, and flows back into the heating cavity 13 through the heating hole 121, and the hot air flow enters the inside of the aerosol generating stick 400 through the end face of the aerosol generating stick 400 under the action of negative pressure, so as to carry the aerosol generated by the atomized substrate to the suction end of the aerosol generating stick 400.

[0070] After use, the mounting shell 2 and the heating base 1 can be taken out of the assembly groove 311 together, so as to replace the aerosol generating stick 400 and clean the residues generated during heating.
