[0034] 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 some instances, details of well-known methods, procedures, components, and networks have not been described in the present disclosure to avoid obscuring aspects of the present application.
[0035] 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 apparent to those skilled in the art. Therefore, the specification and drawings are only intended to clearly describe one embodiment, and do not mean that the composition and / or order is necessary.
[0036] 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.
[0037] 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.
[0038] The heating base device 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. The first air channel extending spirally and communicating with the second air inlet hole is arranged in the heating base. The corresponding second air channel is arranged on the outer end surface 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 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 heating base, the airflow entering the base shell through the first air inlet hole can enter the first air channel of the heating base through the second air inlet hole, move spirally along the first air channel to the outer end surface of the base bottom wall, and then move to the heating hole through the second air channel to flow back into the heating cavity, and then enter the inside of the aerosol generating stick. When applied to the atomization device, the heating member of the atomization device 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 inside of the aerosol generating stick through the end surface of the aerosol generating stick, so as to avoid the direct entry of cold air with low temperature into the aerosol generating stick to cause cold and 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, so that the user does not need to exert a large suction force during the suction action, and the use experience is improved.
[0039] Some embodiments of the heating base device and the atomization device provided by the application will be described below with reference to the accompanying drawings.
[0040] In the embodiments of the first aspect of the application, a heating base device 100 is provided, which comprises a base shell 1 and a heating base 2. Figure 1 Figure 2 Figure 3 Figure 4 As shown, the heating base device 100 comprises a heating base 1 and a base shell 2. The heating base 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 heating base 1 opposite to the base bottom wall 12 has an insertion opening 111 which communicates with the heating cavity 13 and is used for inserting the aerosol generating stick 400 into the heating cavity 13. The base bottom wall 12 is provided with a heating hole 121 which penetrates through the base bottom wall 12 in the first direction and communicates with the heating cavity 13, and is used for passing a heating element when applied to an atomization device, so that the heating element can heat the aerosol generating stick 400 in the heating cavity 13. The inner side of the base side wall 11 is provided with a first air channel 112 which is spirally arranged in the first direction, and the base side wall 11 is provided with a second air inlet hole 115 which penetrates through the base side wall 11, 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 through the base bottom wall 12 and extends to the outer end surface of the base bottom wall 12. Correspondingly, the outer end surface 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 flowing out of the first air channel 112 can flow along the second air channel 122 to the heating hole 121 and flow back to the heating cavity 13 through the heating hole 121. The base shell 2 has a mounting cavity 20, and the heating base 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 heating base 1 is correspondingly arranged at the first opening 21, and the heating cavity 13 of the heating base 1 communicates with the first opening 21. The side wall of the base shell 2 is provided with a first air inlet hole 23 which penetrates through the base shell 2 and communicates with the second air inlet hole 115, and the base shell 2 can be connected and assembled with the shell of the atomization device.
[0041] As shown in Figure 1 and Figure 2 shown, in the state that the aerosol generating stick 400 is inserted into the heating cavity 13, the inner end surface 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 then enter the first air channel 112 through the second air inlet hole 115 of the heating base 1. When the user performs a 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 outer end surface of the base bottom wall 12, it flows along the second air channel 122 to the heating hole 121, and then flows back to the heating cavity 13 through the heating hole 121, and is sucked into the inside of the aerosol generating stick 400 through the inner end surface of the aerosol generating stick 400.
[0042] 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.
[0043] The heating base device 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 heating base 1 to enter the first air channel 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 channel 112 to the outer end face of the base bottom wall 12, and form a hot airflow by being heated. Then, the hot airflow is moved to the heating hole 121 by the second air channel 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 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.
[0044] 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 device 100 has a complete air inlet channel, when applied to the atomization equipment, it is not required to set the air channel inside the shell of the atomization equipment, which is beneficial to the structural design of the whole machine.
[0045] It should be noted that the number of the first air channel 112, the second air channel 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 channel 112 can be selected according to the actual situation. The first air channel 112 can be arranged in a clockwise direction or in a counterclockwise direction.
[0046] 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 heating base 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 heating base 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, setting the air intake gap 28 can also reduce the assembly difficulty when the heating base 1 is installed into the base shell 2, making the assembly operation more convenient.
[0047] 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.
[0048] Of course, in practical applications, an air intake gap may not be set, that is, the outer wall of the heating base 1 abuts against the inner 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.
[0049] In further embodiments of this application, such as Figures 2 to 5 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 heating base 1 where the insertion port 111 is located. The end of the heating base 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 heating base 1 in the first direction and laterally. By providing the stepped groove 27, the base housing 2 and the heating base 1 can be connected and assembled, and the heating base 1 can be limited, so that the heating base device 100 can be assembled and fixed together with the housing of the atomizing device.
[0050] Accordingly, such as Figures 2 to 5As shown in the drawings, the outer side of the side wall 11 of the heating base 1 is provided with a sealing protrusion 113 arranged 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 heating base 1 and the base shell 2, and to support and limit the heating base 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. After the air flow enters the air inlet gap 28 between the base shell 2 and the heating base 1 through the first air inlet hole 23, the air flow can be prevented from flowing out of the first opening 21 or the second opening 22 by the sealing protrusion 113, and the air flow can only enter the first air channel 112 of the heating base 1 through the second air inlet hole 115 to prevent air leakage.
[0051] As shown in the drawings, Figure 2 , Figure 3 the outer side of the sealing protrusion 113 of the heating base 1 is provided with a first clamping structure 114, and the inner side wall of the base shell 2 is provided with 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 achieve connection and fixation.
[0052] In a specific example, as shown in the drawings, Figure 2 , Figure 3 and Figure 6 the first clamping structure 114 and the second clamping structure 24 can be a snap structure and a clamping groove structure. The snap 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 heating base 1. The clamping groove structure is located on the inner side wall of the base shell 2. When the heating base 1 is assembled into the mounting cavity 20 of the base shell 2 in the first direction, the snap structure can be elastically deformed under the extrusion of the inner side wall of the base shell 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.
[0053] It should be noted that in actual application, the snap 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 snap structure is arranged on the inner side wall of the base shell 2, which can also achieve clamping fit. The specific arrangement and clamping principle are similar to the above case, and will not be described here.
[0054] In further embodiments of the present application, as shown in the drawings, Figure 2 , Figure 7 , Figure 8As shown, the first air passage 112 specifically comprises a first spiral groove 1121 which penetrates 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 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 one end of the insertion opening 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 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 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 passage, the external gas enters the first spiral groove 1121 through the second air inlet hole 115, and moves to the outer end face of the base bottom wall 12 along the spiral air passage, forming a spiral airflow, which has stronger power than the disordered movement state, can reduce the resistance in the movement process, and the airflow movement is more stable and smooth.
[0055] 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 according to needs, for example Figure 7 the rectangle shown in
[0056] 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 be able to meet the air inlet flow requirement, while keeping the thickness of the base side wall to meet the strength design requirement.
[0057] Further, the first spiral groove 1121 can be set to Figure 8 and Figure 9 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 stable during the airflow movement.
[0058] Of course, in actual applications, at least part of the groove sections of the first spiral groove 1121 can also be provided in different cross-sectional area structures according to the use requirements. For example, in a specific example, the first spiral groove 1121 can be provided in a gradually decreasing cross-sectional area in the direction extending to the base bottom wall 12, so that the air flow velocity gradually increases, and the air flow can quickly enter the second air channel 122 from the first spiral groove 1121, which is beneficial to promote the movement of the air flow in the second air channel 122, and make the air flow more easily enter the aerosol generating stick.
[0059] 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 size 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, are in an alternating state in the first direction, and are kept at a certain interval to prevent mutual 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 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.
[0060] It should be noted that the above is only one preferred example of the first air channel 112, and the first air channel 112 is not limited to the form of the first spiral groove 1121 described above. For example, the first air channel 112 can also be provided in the form of a closed hole structure. In another specific example, the first air channel 112 can be in 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 provided spirally 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 channel 122. The first spiral hole forms a spiral air channel, 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 the movement of the air flow can be further reduced, and the stability of the air flow movement can be improved.
[0061] In further embodiments of the present application, as Figure 5 , Figure 8 , Figure 10As shown, the heating base 1 has a communication port 123 in the base bottom wall 12, the first air channel 112 on the base side wall 11 extends to the communication port 123 from the end away from the insertion port 111, and the end of the second air channel 122 on the outer end surface of the base bottom wall 12 also extends to the communication port 123, so that 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 surface of the base bottom wall 12 through the communication port 123. Among them, as an example in Figure 8 the projection plane perpendicular to the first direction, the communication port 123 is located outside the projection plane of the insertion port 111, that is, the communication port 123 is located near the outer edge of the base bottom wall 12, corresponding to the base side wall 11, the first air channel 112 extends along the base side wall 11 to the connection with the base bottom wall 12, so as to communicate with the communication port 123 without changing the extension direction; accordingly, the communication port 123 near the outer edge of the base bottom wall 12 can also reserve more space for the arrangement of the second air channel 122 to meet the requirements of airflow transition.
[0062] In further embodiments of the present application, as shown in Figure 5 , Figure 8 and Figure 10 on the outer end surface of the base bottom wall 12, the second air channel 122 specifically includes 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 towards the center position from the outside, and the end of the second spiral groove 1221 near the edge of the base bottom wall 12 is in communication with the first air channel 112, 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. 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 providing 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 direction, thereby reducing airflow impact and disturbance, and at the same time reducing resistance, which is conducive to the smooth flow of the airflow to the heating hole 121.
[0063] In actual application, when multiple first air channels 112 are arranged, multiple second spiral grooves 1221 can also be arranged correspondingly, and similar arrangement can be adopted to enable each second spiral groove 1221 to communicate with one of the first air channels 112, so that multiple air flows can move independently and prevent mutual interference. In addition, the second spiral groove 1221 can also adopt a similar structure as the first air channel 112, for example, the cross-sectional shape can adopt a rectangular, semicircular, triangular shape, etc., and the width of the second spiral groove 1221 can be set according to the spatial position on the base bottom wall 12, for example, as shown in Figure 5 , 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 match the first air channel 112 and the heating hole 121, and the width of the second spiral groove 1221 gradually changes to keep the air flow stable.
[0064] Further, as shown in Figure 8 and Figure 10 , 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 the air flow flows inside the base bottom wall 12. 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 the same to facilitate the stability of air flow movement and also facilitate processing and manufacturing. It should be noted that the depth of the second spiral groove 1221 specifically refers to the distance from the outer end face of the base bottom wall 12 to the groove bottom wall of the second spiral groove 1221 in the first direction.
[0065] Of course, in actual application, the second spiral groove 1221 can also be arranged in different structural forms 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 increased 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 certain slope to guide the air flow and promote the air flow to move in the first direction towards the heating cavity 13 to promote the air inlet at the heating hole 121.
[0066] Further, as shown in Figure 2 , Figure 4 , Figure 7 and Figure 8In 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.
[0067] 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.
[0068] 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.
[0069] An embodiment of the second aspect of this application provides an atomizing device 300, such as... Figure 11 , Figure 12 and Figure 13 As shown, the atomizing device 300 includes a housing 31, a heating base device 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 device 100. The heating base device 100 is partially disposed in the assembly groove 311 and detachably connected to the housing 31. Furthermore, the 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 heating base 1. The heating assembly 32 has a heating element 321 disposed along the first direction toward the heating base 1, and the heating element 321 extends through a heating hole 121 on the base bottom wall 12 into the 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.
[0070] As Figure 2 and Figure 13 shown in the examples in the above, in use, the aerosol generating stick 400 is inserted into the heating cavity 13, and the heating piece 321 penetrates into the inside of the aerosol generating stick 400 to heat the atomized substrate inside the aerosol generating stick 400 to form an aerosol. When a 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 air channel 112 through the first air inlet hole 23 and the second air inlet hole 115 under the action of negative pressure, and then spirally moves along the first air channel 112 to the outer end face of the base bottom wall 12, is heated to form a hot air flow, and then flows to the heating hole 121 through the second air channel 122, and flows back into the heating cavity 13 through the heating hole 121. The hot air flow enters the inside of the aerosol generating stick 400 through the inner 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.
[0071] Through the atomization device 300 in the embodiment, in the state that the aerosol generating stick 400 is inserted into the heating cavity 13, the first air inlet hole 23 of the base shell 2, the second air inlet hole 115 of the heating base 1, the first air channel 112 and the second air channel 122 of the heating base device 100 are used to supply the air flow, 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 the cold air directly entering the inside of the aerosol generating stick 400 to cause a cold-hot confrontation, which is beneficial to enhancing the heating effect. Moreover, the spiral air flow formed can effectively reduce the resistance in the movement process, and the air flow power is stronger, so that the user does not need 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 base 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 lateral wall of the aerosol generating stick 400 can abut against the inner lateral 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.
[0072] The following further introduces a specific example of the atomization device 300 of the present application in combination with the drawings.
[0073] As Figures 11 to 13 shown, the height direction of the shell 31 is the first direction, and the top of the shell 31 is provided with a mounting groove 311. The heating base device 100 of the atomization device 300 specifically includes the heating base 1 and the base shell 2. As Figures 1 to 10As 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, and 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. The base bottom wall 12 has a through 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, one end of the second spiral groove 1221 also extends to the communication port 123, and the first spiral groove 1121 and the second spiral groove 1221 form communication through the communication port 123; 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.
[0074] Wherein, the heating base 1 is made of PEEK (Poly ether-ether-ketone) or PI (Polyimide), such as Figure 8 In the example shown in the figure, 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 .
[0075] As shown in the figure Figures 1 to 3In the example, the base housing 2 has a mounting cavity 20, and the heating base 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 heating base 1 is correspondingly disposed with respect to the first opening 21, and the heating cavity 13 of the heating base 1 communicates with the first opening 21. The base housing 2 has a stepped groove 27 at one end corresponding to the insertion port, and the first opening 21 is specifically located on the bottom wall of the stepped groove 27. The end of the heating base 1 with the insertion port 111 extends into the stepped groove 27, and the end face of the heating base 1 abuts against the bottom wall of the stepped groove 27, while the outer surface of the heating base 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.
[0076] like Figure 2 In the example, the outer side surface of the base sidewall 11 has a circumferentially arranged sealing protrusion 113, which abuts against the inner sidewall of the base shell 2 to form a sealed assembly between the heating base 1 and the base shell 2. The outer side 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 shell 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 heating base 1, and the air inlet gap 28 is connected to the first air inlet 23; the heating base 1 has a second air inlet 115 that extends laterally on its base side wall 11, and the second air inlet 115 is coaxially arranged with the first air inlet 23.
[0077] like Figure 2 , Figures 11 to 13In 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.
[0078] like Figure 13 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 device 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 device 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.
[0079] like Figures 2 to 5 and Figure 13In 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 a 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 air inlet gap 28 through the first air inlet hole 23 under the action of negative pressure, and then enters the first spiral groove 1121 through the second air inlet hole 115, 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 from the heating hole 121. The hot air flow 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, so as to carry the aerosol generated by the atomized substrate to the suction end of the aerosol generating stick 400.
[0080] After use, the base 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.
[0081] The atomization device 300 in the present application has all the beneficial effects of the heating base device 100 in any of the above embodiments, which will not be repeated here.
