Among them, an air inlet hole is usually arranged at the bottom of the heating cavity, and a corresponding air channel structure is arranged in the shell of the heating cavity.

[0036] The application will be described in further detail below with reference to the drawings. Like elements in different embodiments are denoted by like reference numerals. In the following embodiments, many specific details are described in order to provide a thorough understanding of the application. However, it will be apparent to one skilled in the art that the application can be practiced without these specific details. In other instances, well-known methods, procedures, components, and networks have not been described in detail so as not to unnecessarily obscure aspects of the application. In addition, it is to be understood that the phraseology or terminology employed herein, and not the norms of the prior art, are intended to be interpreted to be for the purpose of the application and not intended to be limiting.

[0037] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can be sequentially adjusted or changed in a manner that can be easily understood by those skilled in the art. Therefore, the specification and drawings are only intended to clearly describe one embodiment, and do not mean that the components and / or order are necessary.

[0038] The serial numbers of 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. The "connection" and "coupling" in this application include direct and indirect connection (coupling) unless otherwise specified.

[0039] The aerosol generating stick is a substrate containing an atomization substrate, which can be used with a corresponding atomization device (such as a heat-not-burn device) to heat the aerosol generating stick to atomize the atomization substrate and generate an aerosol.

[0040] The heating base provided by the application can be applied to an atomization device (for example, a heating non-combustion device) to heat and atomize an aerosol generating stick. A first air channel extending spirally and communicating with a second air inlet hole is arranged in the base body. A corresponding second air channel is arranged 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 a heating hole on the base bottom wall. Correspondingly, the first air inlet hole is arranged on the side wall of the base shell, so that when the aerosol generating stick is loaded into the heating cavity in the base body, the airflow entering the base shell through the first air inlet hole can enter the first air channel of the base body through the second air inlet hole, move spirally along the first air channel to the base bottom wall, and then move to the vicinity of the heating hole through the second air channel, and then enter the inside of the aerosol generating stick. When applied to the atomization device, the heating member of the atomization device passes into the heating cavity through the heating hole on the cavity bottom wall of the heating cavity, and heats and atomizes 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. The hot airflow flows into the inside 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 a lower temperature into the aerosol generating stick to cause a cold-hot confrontation, and to facilitate the enhancement of the heating effect. Moreover, the airflow moves spirally in the heating cavity, which can effectively reduce the resistance during the movement of the airflow, and the airflow power is enhanced. The user does not need to exert a large suction force during the suction action, and the use experience is improved.

[0041] Some embodiments of the heating base and the atomization device provided by the application will be described below with reference to the accompanying drawings.

[0042] In the embodiments of the first aspect of the application, a heating base 100 is provided, which comprises a base body 110 and a base shell 120. Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the heating base 100 comprises a base body 1 and a base shell 2. The base body 1 has a base side wall 11 and a base bottom wall 12, and the base side wall 11 and the base bottom wall 12 enclose a heating cavity 13; in the first direction, the end of the base body 1 opposite to the base bottom wall 12 has an insertion opening 111, which communicates with the heating cavity 13, for inserting the aerosol generating stick 400 into the heating cavity 13 through the insertion opening 111. The base bottom wall 12 is provided with a heating hole 121 penetrating in the first direction, which communicates with the heating cavity 13, for allowing the heating member to pass through when applied to the atomization device, so that the heating member can heat the aerosol generating stick 400 in the heating cavity 13. The inner side of the base side wall 11 has a first air channel 112 arranged in a spiral along the first direction, and the base side wall 11 has a second air inlet hole 115 penetrating, the first air channel 112 communicates with the second air inlet hole 115, and one end of the first air channel 112 in the first direction penetrates the base bottom wall 12 and extends to the base bottom wall 12; correspondingly, the inner end face of the base bottom wall 12 is provided with a second air channel 122, which communicates with the first air channel 112 and the heating hole 121, so that the airflow in the first air channel 112 can flow along the second air channel 122 to the vicinity of the heating hole 121, and flow into the inside of the aerosol generating stick 400 from the end face of the aerosol generating stick 400. The base shell 2 has a mounting cavity 20, and the base body 1 is arranged in the mounting cavity 20 and detachably connected with the base shell 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 correspondingly arranged with the first opening 21, and the heating cavity 13 of the base body 1 communicates with the first opening 21. The side wall of the base shell 2 has a penetrating first air inlet hole 23, and the first air inlet hole 23 communicates with the second air inlet hole 115; the base shell 2 can be connected and assembled with the shell of the atomization device.

[0043] As shown in Figure 1 and Figure 2 As shown, in the state that the aerosol generating stick 400 is inserted into the heating cavity 13, the inner end face of the aerosol generating stick 400 abuts against the base bottom wall and is opposite to the heating hole; the external airflow can enter the mounting cavity 20 through the first air inlet hole 23 of the base shell 2, and enter the first air channel 112 through the second air inlet hole 115 of the base body 1. When the user performs the suction action on the aerosol generating stick 400, the airflow spirally moves along the first air channel 112 in the direction close to the base bottom wall under the action of negative pressure, and forms a hot airflow under heating; when the airflow moves to the base bottom wall 12, it flows along the second air channel 122 to the vicinity of the heating hole 121, and is then sucked into the inside of the aerosol generating stick 400.

[0044] 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 inside of the aerosol generating stick, that is, the temperature of the atomized substrate is reduced, thereby affecting the atomization effect.

[0045] The heating base 100 in the embodiment can, by improving and optimizing the structure, utilize the first air inlet hole 23 of the base shell 2 and the second air inlet hole 115 of the base body 1 to enter the first air duct 112 arranged in a spiral when the aerosol generating stick 400 is assembled in the heating cavity 13. The airflow can spiral along the first air duct 112 to the base bottom wall 12, and form a hot airflow by being heated. Then, the hot airflow is moved to the vicinity of the heating hole 121 by the second air duct 122 of the inner end surface 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 400, 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. The user does not need to exert a large suction force when performing the suction action, which is beneficial to improving the use experience.

[0046] In addition, since the air is not required to be inhaled through the first opening 21 of the base shell 2, the size of the first opening 21 can be set to be matched with the aerosol generating stick 400. When the aerosol generating stick 400 is inserted through the first opening 21 to the heating cavity 13, the inside edge of the first opening 21 can abut against the aerosol generating stick 400, which is beneficial to keeping the aerosol generating stick 400 stable and preventing it from falling off. Moreover, since the heating base 100 has a complete air inlet air duct, when applied to the atomization equipment, it is not required to set the air duct inside the shell of the atomization equipment, which is beneficial to the structural design of the whole machine.

[0047] It should be noted that the number of the first air duct 112, the second air duct 122, the first air inlet hole 23 and the second air inlet hole in the embodiment can be one or more. Moreover, the rotation direction of the first air duct 112 can be selected according to the actual situation. The first air duct 112 can be arranged in a clockwise direction or in a counterclockwise direction.

[0048] In further embodiments of the present application, as Figure 2In the example shown, in the lateral direction, an air intake gap 28 is formed between the base body 1 and the base shell 2, and the two ends of the air intake gap 28 are sealed in the first direction. The first air intake hole 23 and the second air intake hole 115 are both connected to the air intake gap 28. When external air flows into the air intake gap 28 through the first air intake hole 23, it can flow within the air intake gap 28 (including flowing along the first direction or along the circumferential direction), and thus can flow into the first air passage 223 inside the base body 1 through the second air intake hole 115. By setting the air intake gap 28, it can serve as an airflow transition area. Even if the first air intake hole 23 and the second air intake hole 115 are misaligned, the airflow can still flow normally into the first air passage 112. At the same time, by setting the air intake gap 28, the assembly difficulty can be reduced when the base body 1 is installed into the base shell 2, and the assembly operation is more convenient.

[0049] Furthermore, such as Figure 2 In the example, the first air inlet 23 and the second air inlet 115 are coaxially arranged, that is, the first air inlet 23 and the second air inlet 115 are laterally aligned. After the external air flows in through the first air inlet 23, it can directly pass through the second air inlet 115 and enter the first air passage, which can greatly shorten the airflow path and promote air intake.

[0050] Of course, in practical applications, an air intake gap may not be set, that is, the outer side wall of the base body 1 abuts against the inner side wall of the base shell 2. In this case, by setting the first air intake hole 23 and the second air intake hole 115 coaxially, the first air intake hole 23 and the second air intake hole 115 are not blocked, and normal air intake can also be guaranteed.

[0051] In further embodiments of this application, such as Figures 2 to 4 In the example, the base housing 2 has a stepped groove 27 at one end corresponding to the insertion port 111, and the first opening 21 is specifically located on the bottom wall of the stepped groove 27. The shape of the stepped groove 27 is adapted to the shape of the end of the base body 1 where the insertion port 111 is located. The end of the base body 1 where the insertion port 111 is located extends into the stepped groove 27 and abuts against the inner wall surface of the stepped groove 27 (including abutting against the inner side wall and the bottom wall of the groove), so as to limit the base body 1 in the first direction and laterally. By providing the stepped groove 27, the base housing 2 and the base body 1 can be connected and assembled, and the stepped groove 27 can limit the base body 1, so that the heating base 100 can be assembled and fixed together with the housing of the atomizing device, while preventing the airflow from flowing out from the first opening 21.

[0052] Furthermore, such as Figures 2 to 5As shown, the base body 1 has a sealing protrusion 113 arranged on the outer side of the base side wall 11 in the circumferential direction, and the sealing protrusion 113 abuts against the inner side wall of the base shell 2 to form a sealed assembly between the base body 1 and the base shell 2, and to support and limit the base body 1 in the lateral direction. In the first direction, the first air inlet hole 23 and the second air inlet hole 115 are arranged between the sealing protrusion 113 and the stepped groove 27, and after the airflow enters the air inlet gap 28 between the base shell 2 and the base body 1 through the first air inlet hole 23, the airflow can be prevented from flowing out of the second opening 22 by the sealing protrusion 113.

[0053] As shown in Figure 2 , Figure 4 , the base body 1 has a first clamping structure 114 arranged on the outer side of the sealing protrusion 113, and the inner side wall of the base shell 2 has a second clamping structure 24 corresponding to the first clamping structure 114, and the second clamping structure 24 and the corresponding first clamping structure 114 form a clamping fit to achieve connection and fixation.

[0054] In a specific example, as shown in Figure 2 , Figures 4 to 6 , the first clamping structure 114 and the second clamping structure 24 can be a spring buckle structure and a clamping groove structure, the spring buckle structure is connected to one end of the sealing protrusion 113 away from the insertion opening 111 and maintains a certain gap with the outer side wall of the base body 1, and the clamping groove structure is arranged on the inner side wall of the base shell 2; when the base body 1 is assembled into the mounting cavity 20 of the base shell 2 in the first direction, the spring buckle structure can be elastically deformed under the extrusion of the inner side wall of the base shell 2, and when the spring buckle structure moves to the position corresponding to the clamping groove structure, the spring buckle structure resets and extends into the clamping groove structure to form a clamping fit.

[0055] It should be noted that in actual application, the spring buckle structure and the clamping groove structure can also be interchanged, i.e. the clamping groove structure is arranged on the outer side wall of the sealing protrusion 113, and the spring buckle structure is arranged on the inner side wall of the base shell 2, which can also achieve a clamping fit, and the specific arrangement and clamping principle are similar to the above case, which will not be described here.

[0056] In further embodiments of the present application, as shown in Figure 2 , Figure 5 , Figure 7As shown, the first air passage 112 specifically comprises a first spiral groove 1121 which extends through the inner side of the base side wall 11 in the lateral direction, i.e. 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 interior of the base body 1; in the first direction, the first spiral groove 1121 is arranged in a spiral shape, the first spiral groove 1121 is in communication with the second air inlet hole 115, and one end of the first spiral groove 1121 extends to the inner end face of the base bottom wall 12 and is in communication with the second air passage 122. When the aerosol generating stick 400 is loaded into the heating cavity 13, as shown in the state shown in Figure 2 the aerosol generating stick 400 abuts against the inner side of the base side wall 11 or maintains a small gap, the first spiral groove 1121 forms a spiral air passage, the external gas enters the first spiral groove 1121 through the second air inlet hole 115, and moves along the spiral air passage to the inner end face of the base bottom wall 12, forming a spiral airflow, which has stronger power than the disordered motion state, can reduce the resistance in the motion process, and the airflow motion is more stable and smooth.

[0057] In actual application, the cross-sectional shape of the first spiral groove 1121 can adopt a rectangle, a semicircle, a triangle, etc., of course, it can also be set to other shapes suitable for airflow passing, for example Figure 8 the rectangle shown in

[0058] Further, as shown in the examples in Figure 8 and Figure 9 , 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 intake flow requirement, while maintaining a certain thickness of the base side wall to meet the strength design requirement.

[0059] Further, the first spiral groove 1121 can be set to Figure 7 and Figure 8 the equal cross-section form shown in, i.e. the cross-sectional area is the same in the extension direction of the first spiral groove 1121, and always remains consistent, so as to keep the airflow stable during motion.

[0060] Of course, in actual application, at least part of the groove section of the first spiral groove 1121 can be set to a structure form with different cross-sectional areas according to the use requirement. For example, in a specific example, the cross-sectional area of the first spiral groove 1121 can be gradually reduced in the direction extending to the base bottom wall 12, so as to gradually increase the airflow velocity, so that the airflow can quickly enter the second air passage 122 from the first spiral groove 1121, which is beneficial to promote the motion of the airflow in the second air passage 122, and make the airflow more easily enter the interior of the aerosol generating stick.

[0061] Additionally, the number of turns and pitch (i.e., the distance between corresponding points of two adjacent turns in the first direction) of the first spiral groove 1121 can be set according to the dimensions of the base body 1 in the first direction. When the pitch 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 volume. The multiple first spiral grooves 1121 are circumferentially phase-differentiated to alternate 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 circumferentially. In the first direction, another first spiral groove 1121 is provided between two adjacent turns of one first spiral groove 1121.

[0062] It should be noted that the above is only a 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 configured as a closed hole structure. In another specific example, the first air passage 112 can take the form of a first spiral hole, which is located inside the base sidewall 11, that is, no openings are provided on either the inner or outer sides in the lateral direction. The first spiral hole is spirally arranged in a first direction and communicates with the second air inlet 115. One end of the first spiral hole extends to the inner 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 external gas can enter the first spiral hole from the end face of the base sidewall 11 and move spirally along the first spiral hole to the inner end face of 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 the airflow movement can be further reduced, thereby improving the stability of the airflow movement.

[0063] In further embodiments of this application, such as Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, on the inner end face of the base bottom wall 12, the second air passage 122 specifically includes a second spiral groove 1221. The spiral direction of the second spiral groove 1221 is the same as that of the first air passage 112, so that the airflow can smoothly transition from the first air passage 112 to the second air passage 122. The second spiral groove 1221 is specifically in a state of gradually contracting from the outside to the center. One end of the second spiral groove 1221 near the edge of the base bottom wall 12 is connected to the first air passage 112, and the other end of the second spiral groove 1221 extends to the side edge of the heating hole 121 and is connected to the heating hole 121. After the airflow enters the second air passage 122 from the first air passage 112, it can continue to flow towards the heating hole 121 in a spiral state. By setting the second spiral groove 1221, the airflow can be made to move in a spiral motion when flowing on the inner end face of the base bottom wall 12. This can avoid the phenomenon of sudden change in the direction of airflow, thereby reducing airflow impact and disturbance. At the same time, it can reduce resistance and facilitate the smooth and stable flow of airflow to the heating hole 121.

[0064] In practical applications, when multiple first air passages 112 are provided, multiple second spiral grooves 1221 can also be provided accordingly. Using a similar arrangement, each second spiral groove 1221 is connected to one of the first air passages 112, allowing multiple airflows to move independently and preventing mutual interference. Furthermore, the second spiral grooves 1221 can also adopt a similar structural form to the first air passages 112; for example, their cross-sectional shape can be rectangular, semi-circular, or triangular. Moreover, the width of the second spiral grooves 1221 can be set according to their spatial position on the base bottom wall 12. Figure 11 and Figure 12 In the example, the width of the second spiral groove 1221 can be increased in areas with larger spaces, while the width of the second spiral groove 1221 can be decreased near the base sidewall 11 and near the heating hole 121 to adapt to the first air passage 112 and the heating hole 121. The width dimension of the second spiral groove 1221 is gradually changed to keep the airflow movement stable.

[0065] Furthermore, such as Figure 7 and Figure 8 In the example shown, in the first direction, the bottom wall of the second spiral groove 1221 is located between the inner and outer end faces of the base bottom wall 12, so that the airflow flows inside the base bottom wall 12. Furthermore, in the first direction, the depth of the second spiral groove 1221 is uniform; that is, different sections of the second spiral groove 1221 maintain a consistent depth to facilitate airflow stability and manufacturing. 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 bottom wall of the second spiral groove 1221 in the first direction.

[0066] Of course, in practical applications, the second spiral groove 1221 can also be configured with different depths in different areas 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 bottom wall of the second spiral groove 1221 forms a certain slope to guide the airflow and promote the airflow to move towards the heating cavity 13 in the first direction, so as to promote the air intake at the heating hole 121.

[0067] Furthermore, such as Figure 7 , Figure 8 , Figure 10 and Figure 11 In the example shown, the heating chamber 13 is a cylindrical cavity adapted to fit the shape of the aerosol generating rod 400. Correspondingly, the heating hole 121 is located at the center of the base bottom wall 12 and is coaxially arranged with the heating chamber 13, corresponding to the central region of the inner end face of the aerosol generating rod 400. After the heating element extends into the heating chamber 13 through the heating hole 121, it can penetrate into the interior of the aerosol generating rod 400 near the center, thus making the heating more uniform. Simultaneously, the location of the heating hole 121 at the center of the base bottom wall 12 also facilitates the arrangement of the second spiral groove 1221.

[0068] In further embodiments of this application, such as Figures 1 to 3 In the example shown, the outer wall of the base housing 2 has a third snap-fit ​​structure 25, which allows it to snap into and fix the housing when assembled into the housing of the atomizing device. It should be noted that the third snap-fit ​​structure 25 is not limited to the form of the snap-fit ​​protrusion shown in the figure, and can be specifically set according to the specific matching structure of the housing.

[0069] In further embodiments of this application, such as Figures 1 to 3 In the example, the outer wall of the base housing 2 has a boss structure 26 near the first opening 21, and the first air inlet 23 extends laterally through the boss structure 26. When assembled with the housing of the atomizing device, the boss structure 26 abuts against the housing so that part of the base housing 2 is inserted into the housing, while the portion of the base housing 2 with the first opening 21 and the first air inlet 23 is located outside the housing for easy disassembly.

[0070] An embodiment of the second aspect of this application provides an atomizing device 300, such as Figure 13 , Figure 14 and Figure 15As 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. A first air inlet 23 on the base housing 2 communicates with the external atmosphere. The heating assembly 32 is disposed within the housing 31 and is correspondingly disposed in the first direction to the base bottom wall 12 of the base body 1. The heating assembly 32 has a heating element 321 disposed along the first direction toward 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 an 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.

[0071] like Figure 2 and Figure 15 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. 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 through the first air inlet 23 and the second air inlet 115, and then spirals along the first air passage 112 to the inner end face of the base bottom wall 12, where it is heated to form a hot airflow. The hot airflow then flows through the second air passage 122 to the vicinity of the heating hole 121, and under negative pressure, enters the interior of the aerosol generating rod 400 from its inner end face, carrying the aerosol generated by the atomizing matrix to the suction end of the aerosol generating rod 400.

[0072] The atomizing device 300 in this embodiment allows airflow to pass through the heating base 100 when the aerosol generating rod 400 is inserted into the heating chamber 13. This airflow is generated by the first air inlet 23 of the base shell 2, the second air inlet 115 of the base body 1, the first air passage 112, and the second air passage 122. The airflow forms a spiral motion and is heated to form a hot airflow, which then flows into the aerosol generating rod 400 from near the heating hole 121. This avoids cold air directly entering the aerosol generating rod 400 and causing a hot-cold clash, thus enhancing the heating effect. Moreover, the spiral airflow effectively reduces resistance during movement, resulting in stronger airflow power. Users do not need to exert a large suction force when performing inhalation, which improves the user experience. The housing 31 of the atomizing device 300 does not require additional air passages, which is beneficial for the overall structural design of the device. In addition, since the side air intake method is adopted, the size of the first opening 21 of the base shell 2 can be set to be adapted to the aerosol generating rod 400 so that the outer wall of the aerosol generating rod 400 can abut against the inner edge of the first opening 21 after the aerosol generating rod 400 is inserted into the heating chamber 13, so as to use the friction force to limit the aerosol generating rod 400 and prevent the aerosol generating rod 400 from falling off.

[0073] The following describes a specific example of the atomizing device 300 of this application in conjunction with the accompanying drawings.

[0074] like Figures 13 to 15 As shown, the height direction of the housing 31 is the first direction, and an assembly groove 311 is provided on the top of the housing 31. The heating base 100 of the atomizing device 300 specifically includes a base body 1 and a base shell 2. Figures 1 to 12As shown, the base body 1 is a cylindrical structure with a base side wall 11 and a base bottom wall 12. The base body 1 contains a cylindrical heating cavity 13 formed by the base side wall 11 and the base bottom wall 12. The size of the heating cavity 13 is adapted to the aerosol generating rod 400. In the first direction, an insertion port 111 is provided at one end of the base body 1 opposite to the base bottom wall 12, and the insertion port 111 communicates with the heating cavity 13. A heating hole 121 communicating with the heating cavity 13 is provided on the base bottom wall 12. 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 surface of the base sidewall 11 has a first air passage 112, which specifically includes a spirally arranged first spiral groove 1121. One end of the first air passage 112 passes through the end face of the base sidewall 11 and communicates with the insertion port 111. The other end of the first air passage 112 extends to the inner end face of the base bottom wall 12. A second air passage 122 is correspondingly arranged on the inner end face of the base bottom wall 12. The second air passage 122 specifically includes a spirally arranged second spiral groove 1221, and the spiral direction of the second spiral groove 1221 is the same as that of the first spiral groove 1121. The second spiral groove 1221 is in a state of gradually shrinking from the outside to the center. In the first direction, the 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. The base bottom wall 12 has a through-hole 123. One end of the first spiral groove 1121 away from the insertion port 111 extends to the through-hole 123. One end of the second spiral groove 1221 also extends to the through-hole 123 and communicates with the first spiral groove 1121 through the through-hole 123. The other end of the second spiral groove 1221 extends to the side edge of the heating hole 121 and communicates with the heating hole 121.

[0075] The base body 1 is made of PEEK (Poly ether-ether-ketone) or PI (Polyimide) material, such as... Figure 8 In the example, both the first helical groove 1121 and the second helical groove 1221 have rectangular cross-sections, and the cross-sectional area of ​​the first helical groove 1121 is 0.2 mm. 2 Up to 5mm 2 Within the range.

[0076] like Figures 1 to 4In the example, the base housing 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. The end of the base housing 2 corresponding to the insertion port has a stepped groove 27, and the first opening 21 is specifically located on the bottom wall of the stepped groove 27. The 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, and the outer surface of the base body 1 abuts against the inner surface of the stepped groove 27. The shape of the first opening 21 is adapted to the aerosol generating rod 400. When the aerosol generating rod 400 passes through the first opening 21 and is inserted into the heating cavity 13, as... Figure 2 In the example, the outer wall of the aerosol generating rod 400 abuts against the inner edge of the first opening 21 to limit the aerosol generating rod 400 by means of friction.

[0077] like Figure 2 and Figure 4 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 base housing 2 to form a sealed assembly between the base body 1 and the base housing 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 base housing 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. The base housing 2 has a first air inlet 23 that extends laterally on its side wall, and the first air inlet 23 is located between the sealing protrusion 113 and the stepped groove 27; in the lateral direction, an air inlet gap 28 is formed between the base housing 2 and the base body 1, and the air inlet gap 28 is connected to the first air inlet 23; the base side wall 11 of the base body 1 has a second air inlet 115 that extends laterally, and the second air inlet 115 is coaxially arranged with the first air inlet 23.

[0078] like Figure 2 , Figures 13 to 15In 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 base housing 2. When the end of the base 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 base housing 2 with the first opening 21 is located outside the mounting groove 311. The first 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 first air inlet 23, so that the external airflow can smoothly enter the first air inlet 23. The outer wall of the portion of the base 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 base 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 base 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 base 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.

[0079] like Figure 15 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 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 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 is also 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.

[0080] like Figures 2 to 5 and Figure 15In the example, when the aerosol generating rod 400 is inserted into the heating chamber 13, the heating element 321 penetrates into the interior of the aerosol generating rod 400 to heat the atomizing matrix inside the aerosol generating rod 400 to form an aerosol. 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 air intake gap 28 through the first air intake hole 23 under negative pressure, and then enters the first spiral groove 1121 through the second air intake hole 115. It then spirals along the first spiral groove 1121 to the inner end face of the base bottom wall 12, where it is heated to form a hot airflow. The hot airflow then flows through the second spiral groove 1221 to the heating hole 121, and enters the interior of the aerosol generating rod 400 from the inner end face under negative pressure, carrying the aerosol generated by the atomizing matrix to the suction end of the aerosol generating rod 400.

[0081] After use, the base shell 2 and the base body 1 can be removed together from the assembly slot 311 to facilitate the replacement of the aerosol generating rod 400 and to facilitate the removal of residues generated during heating.

[0082] The atomizing device 300 in this application has all the beneficial effects of the heating base 100 in any of the above embodiments, which will not be repeated here.

[0083] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
