Description

Technical Field

[0001] This application relates to the field of atomization equipment technology, specifically to a heating base device and an atomization device. Background Technology

[0002] Currently, in atomizing devices employing central heating, a heating column or needle is typically inserted into the heating chamber to allow the aerosol generator rod to be inserted and heated when it is assembled within the chamber. To accommodate the shape of the aerosol generator rod, the heating chamber is usually cylindrical. However, this design makes it difficult to create an air intake channel within the heating chamber. Therefore, a vent is typically located at the bottom of the heating chamber, and air intake holes are also provided on the bottom or side wall of the outer shell. Cold air from outside flows in through these air intake holes and enters the heating chamber directly without heating, being drawn directly into the aerosol generator rod. This can easily cause a hot-cold reaction, affecting the heating effect of the aerosol generator rod and impacting the user experience. Utility Model Content

[0010] In a further embodiment of this application, the outer wall of the heating base has a protrusion at a position corresponding to the air guide groove. The protrusion is an arc-shaped structure adapted to the air guide groove, and the wall thickness of the heating base remains consistent in the circumferential direction; and / or, in the first direction, the end of the air guide groove away from the insertion port has a first notch, and the first notch penetrates the air guide groove laterally.

[0034] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0035] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0036] An aerosol generator is a substrate containing an atomizing matrix that can be used with corresponding atomization equipment. Heating the aerosol generator causes the atomizing matrix to atomize and generate aerosols. Different atomizing matrix materials produce aerosols with different flavors to meet diverse user needs.

[0037] The heating base device provided in this application can be used in atomizing equipment to heat and atomize aerosol generating rods. By employing a nested mounting sleeve and a heating base, a first air inlet is provided on the side wall of the mounting sleeve, and a guiding groove extending in a first direction is provided on the inner side wall of the heating base. A second air inlet extending laterally is provided within the guiding groove to achieve lateral air intake. Simultaneously, when the heating chamber contains the aerosol generating rod, airflow can be supplied through the guiding groove. When applied in atomizing equipment, the heating element of the atomizing equipment is inserted into the heating chamber through the heating holes on the bottom wall of the heating chamber, and the aerosol generating rod is heated and atomized. The airflow is guided to the outer wall of the bottom wall of the chamber through the air guide groove. At the same time, the airflow is heated in the heating chamber to form a hot airflow. The hot airflow then flows into the interior of the aerosol generating rod through the vent holes on the bottom wall of the chamber. This avoids the cold air with a lower temperature directly entering the aerosol generating rod and causing a cold-heat collision, which helps to enhance the heating effect. Moreover, since the side air intake is adopted, there is no need to leave an air intake gap between the insertion port and the aerosol generating rod. The insertion port can be used to abut against the side wall of the aerosol generating rod to improve the assembly stability of the aerosol generating rod.

[0038] The following describes some embodiments of the heating base device and atomizing equipment provided in this application with reference to the accompanying drawings.

[0039] An embodiment of the first aspect of this application provides a heating base device 100, such as... Figure 1 , Figure 2 , Figure 3 As shown, the heating base device 100 includes a mounting sleeve 1 and a heating base 2. The mounting sleeve 1 has a mounting cavity 11 that extends through the device along a first direction. At least one first air inlet 16 is provided on the side wall of the mounting sleeve 1, and the first air inlet 16 communicates with the mounting cavity 11. The heating base 2 is disposed within the mounting cavity 11 and is detachably connected to the mounting sleeve 1. When applied to an atomizing device, the mounting sleeve 1 is used for assembly and fixation with the housing of the atomizing device. One end of the mounting cavity 11 in the first direction has an insertion port 12, corresponding to which, for example... Figure 3 , Figure 4 and Figure 5 In the example, the heating base 2 has a heating cavity 21, and the heating cavity 21 extends through one end toward the insertion port 12, allowing the aerosol generating rod 6 to be inserted into the heating base 2 through the insertion port 12; as shown Figure 3 , Figure 6 and Figure 7As shown, the heating chamber 21 has a bottom wall 22 at the end away from the insertion port 12. The bottom wall 22 can abut against the end face of the aerosol generating rod 6 inserted into the heating chamber 21. The bottom wall 22 has a heating hole 221 and a vent hole 222. The heating hole 221 allows the heating element of the atomizing device to pass through and be inserted into the aerosol generating rod 6 for heating. The inner wall of the heating base 2 has at least one air guide groove 211. The air guide groove 211 extends along a first direction and penetrates both ends of the heating base 2. A second air inlet 25 is provided in the air guide groove 211, which is laterally penetrating. External airflow can sequentially pass through the first air inlet 16 and the second air inlet 25 into the heating chamber 21. Figures 6 to 7 As shown, with the aerosol generating rod 6 inserted into the heating chamber 21, external airflow can still enter the air guide groove 211 of the heating base 2 through the first air inlet 16 and the second air inlet 25. When the user performs a suction action on the aerosol generating rod 6, the airflow flows along the air guide groove 211 to the outside of the bottom wall 22 of the chamber under the action of negative pressure, and is heated to form a hot airflow during the flow. Then the hot airflow flows back into the heating chamber 21 through the vent 222 of the bottom wall 22 of the chamber and enters the interior of the aerosol generating rod 6 through the end face of the aerosol generating rod 6.

[0040] It is understandable that aerosol generators require heating during use to atomize the atomizing matrix and produce aerosols. The atomization process has specific temperature requirements; if the temperature does not reach the preset threshold, the atomization effect will be affected. The atomized aerosol needs to be carried to the suction end by the airflow generated by the suction action. Therefore, if the temperature of the intake airflow is low (e.g., cold air), it will create a thermal shock effect on the atomizing matrix after entering the aerosol generator, thus lowering the matrix temperature and affecting the atomization effect.

[0041] The heating base device 100 in this embodiment, through structural improvements and optimizations, enables sidewall air intake when the aerosol generating rod is assembled in the heating chamber. This is achieved through the first air inlet of the mounting sleeve and the second air inlet of the heating base. The airflow passes through the air guide groove on the inner sidewall of the heating base and flows to the outer side of the chamber bottom wall, where it is heated to form a hot airflow. This hot airflow then flows into the aerosol generating rod through the vent on the bottom wall of the groove. This avoids cold air directly entering the aerosol generating rod and causing a hot-cold clash, thus enhancing the heating effect. Furthermore, the heating base device has a simple overall structure, eliminating the need for a pre-reserved air intake gap at the insertion port. The insertion port can directly contact the aerosol generating rod, enhancing the assembly stability of the aerosol generating rod and preventing it from detaching from the heating chamber during use. It is effectively compatible with existing atomizing equipment, simplifies the manufacturing process, and improves the user experience.

[0042] It should be noted that the number of air guide grooves 211 in this embodiment can be one or more, and the shape of the air guide grooves 211 and their specific positions in the circumferential direction of the heating chamber 21 can also be selected according to the actual situation, and are not limited to the state shown in the accompanying drawings of this embodiment.

[0043] In further embodiments of this application, such as Figure 6 and Figure 7 As shown, in the lateral direction, there is a certain gap between the heating base 2 and the mounting sleeve 1, forming a gap chamber 111, and in the first direction, both ends of the gap chamber 111 are sealed. Correspondingly, the first air inlet 16 and the second air inlet 25 are both located at positions corresponding to the gap chamber 111, and both the first air inlet 16 and the second air inlet 25 are connected to the gap chamber 111, so that the intake airflow flows into the gap chamber 111 through the first air inlet 16, and then flows into the heating chamber 21 through the second air inlet 25, and flows along the air guide groove 211 towards the bottom wall 22 of the chamber. By setting a gap chamber 111 to act as an air intake transition between the first air intake port 16 and the second air intake port 25, the first air intake port 16 and the second air intake port 25 do not need to be precisely aligned to achieve effective air intake, and the problem of air intake port blockage will not occur. This reduces the position requirements in the design and assembly process and helps to improve assembly efficiency. At the same time, the gap chamber 111 can also play a certain role in air storage, which can prevent the phenomenon of poor air intake.

[0044] In further embodiments of this application, such as Figure 7 and Figure 8 As shown, the mounting sleeve 1 has a stepped groove 13 at one end near the insertion port 12, and the insertion port 12 is specifically located on the bottom wall of the stepped groove 13. The shape of the stepped groove 13 is adapted to the shape of the end of the heating base 2 facing the insertion port 12. The end of the heating base 2 facing the insertion port 12 extends into the stepped groove 13, and the end face of the heating base 2 abuts against the bottom wall of the stepped groove 13 to seal the top of the gap chamber 111. The size of the insertion port can be designed according to the size of the adapted aerosol generating rod 6, so that when the aerosol generating rod 6 is inserted into the heating chamber 21 through the insertion port 12, the inner edge of the insertion port 12 abuts against the side wall of the aerosol generating rod 6 in the circumferential direction. Figure 5 The state shown in the figure utilizes friction to generate a certain resistance force on the aerosol generating rod 6, preventing the aerosol generating rod 6 from detaching from the heating chamber during use, which helps to enhance the assembly stability of the aerosol generating rod.

[0045] It is understandable that when a user inhales from the aerosol generator, the aerosol generator may stick to the user's mouth. Additionally, moving the atomizing device may cause relative movement of the aerosol generator. These situations can lead to instability in the aerosol generator's assembly, or even cause it to detach from the heating chamber, affecting the user experience. The above-mentioned design in this embodiment effectively alleviates these problems.

[0046] Furthermore, such as Figures 7 to 9 As shown, the outer wall of the heating base 2 is also provided with a sealing protrusion 24, which is arranged around the circumference of the heating base 2, and the outer wall of the sealing protrusion 24 abuts against the inner wall of the mounting sleeve 1. In the first direction, the space between the sealing protrusion 24 and the stepped groove 13 forms a gap chamber 111, and the bottom of the gap chamber 111 is sealed by the sealing protrusion 24. The sealing protrusion 24 has a plurality of first snap-fit ​​structures 241, which are spaced apart in the circumference of the heating base 2. Correspondingly, a plurality of second snap-fit ​​structures 14 are provided on the inner wall of the mounting sleeve 1. Each second snap-fit ​​structure 14 is correspondingly provided with one of the first snap-fit ​​structures 241 and is snapped and fixed to each other to realize the assembly and fixation between the heating base 2 and the mounting sleeve 1.

[0047] Specifically, the first snap-fit ​​structure 241 and the second snap-fit ​​structure 14 can be as follows: Figure 6 The spring-loaded structure and the slot structure shown are connected to the end of the sealing protrusion 24 away from the insertion port 12 and maintain a certain gap with the outer side wall of the heating base 2. The slot structure is located on the inner side wall of the mounting sleeve 1. When the heating base 2 is inserted into the mounting cavity 11 of the mounting sleeve 1 in the first direction, the spring-loaded structure can undergo a certain elastic deformation under the compression of the inner side wall of the mounting sleeve 1. When the spring-loaded structure moves to be aligned with the slot structure, the spring-loaded structure resets and extends into the slot structure to form a snap-fit.

[0048] It should be noted that in practical applications, the spring-loaded structure and the slot structure can also be interchanged. That is, a slot structure can be set on the outer side wall of the heating base 2, while a spring-loaded structure can be set on the inner side wall of the mounting sleeve 1. This can also achieve a snap-fit ​​connection. The specific setting method and snap-fit ​​principle are similar to those described above, and will not be repeated here.

[0049] In further embodiments of this application, such as Figure 7 and Figure 10 As shown, in the heating base 2, the heating cavity 21 includes a central cavity 212 and a recessed cavity 213. On a projection plane perpendicular to the first direction, as... Figure 10In the example shown, the central cavity 212 is located at the center of the heating base 2, and the shape of the central cavity 212 is adapted to the shape of the aerosol generating rod 6. The insertion port 12 is located entirely inside the central cavity 212, or the insertion port 12 coincides with the central cavity 212. In use, the aerosol generating rod 6 occupies the space of the central cavity 212 when inserted into the heating cavity 21. The inner wall of the heating cavity 21 defines at least a portion of the circumferential boundary of the central cavity 212. The recessed cavity 213 is located outside the central cavity 212 and is formed between the inner wall of the air guiding groove 211 and the central cavity 212. External airflow enters the recessed cavity 213 through the first air inlet 16 and the second air inlet 25, then flows through the recessed cavity 213 along a first direction, flows to the outside of the cavity bottom wall 22, and then flows into the interior of the aerosol generating rod 6 through the vent 222 on the cavity bottom wall 22.

[0050] Furthermore, such as Figure 7 and Figure 8 In the example, the central cavity 212 is specifically a cylindrical cavity. Since the aerosol generating rod 6 is typically cylindrical, the central cavity 212 also adopts a corresponding cylindrical shape so that when the aerosol generating rod 6 is inserted into the central cavity 212, the inner wall of the central cavity 212 can limit the aerosol generating rod 6, preventing the recessed cavity 213 from being blocked. For example, Figure 10 In the example shown, on the projection plane perpendicular to the first aspect, the inner wall of the air-guiding groove 211 is an arc-shaped surface. This allows the arc-shaped wall to connect smoothly with the circular wall of the central cavity 212, resulting in a more efficient connection and higher space utilization. The resulting groove cavity 213 occupies relatively less space for the same area, making it easier to meet strength and other requirements during design and manufacturing. Furthermore, the arc-shaped inner wall of the air-guiding groove 211 also guides the airflow, allowing it to flow more smoothly within the groove cavity 213 and reducing airflow disturbance compared to other shapes.

[0051] Furthermore, such as Figure 10 In the example, within the heating chamber 21, on a plane perpendicular to the first direction, the line connecting the two endpoints of the arc segment of the arc surface of the air guide groove 211 is the chord corresponding to the arc surface, and the direction perpendicular to the chord is the second direction. In the second direction, the distance L between the inner wall surface of the air guide groove 211 and the boundary of the central cavity 212 is in the range of 0.1mm to 1mm. In practical applications, the appropriate distance can be set according to the specific wall thickness of the heating base 2 and the corresponding air intake requirements. For example, the maximum distance between the arc surface and the chord can be set to 0.5mm.

[0052] In further embodiments of this application, such as Figures 7 to 10As shown, the outer wall of the heating base 2 has a protrusion 23 corresponding to the air guide groove 211. The protrusion 23 has an arc-shaped structure adapted to the air guide groove 211, and the protruding direction of the protrusion 23 is consistent with the concave direction of the air guide groove 211. Furthermore, the wall thickness of the heating base 2 remains consistent in the circumferential direction to meet the strength requirements and design and processing requirements of the heating base 2, while also satisfying the corresponding heat insulation requirements. It is understood that if the wall thickness of the heating base 2 at the location of the air guide groove 211 is less than the wall thickness at other locations, the strength of that area will be reduced, and the heat insulation capacity of that area will also be correspondingly lower than other areas, easily causing uneven temperature distribution inside the heating cavity 21. In this embodiment, by providing a protrusion 23 adapted to the air guide groove 211, the above problems can be effectively alleviated.

[0053] Furthermore, such as Figure 7 and Figure 8 As shown, the protrusion 23 of the heating base 2 has a first notch 231 at the end away from the insertion port 12 in the first direction, and the first notch 231 communicates with the end of the corresponding air guide groove 211 away from the insertion port 12. This means that the groove cavity 213 not only has an opening that penetrates the bottom wall 22 of the cavity along the first direction, but also has a first notch 231 that communicates with it in the lateral direction. This further increases the opening area of ​​the groove cavity 213 at the end away from the insertion port 12, which is conducive to gas flow. At the same time, it can reduce the airflow velocity at the opening and alleviate the airflow impact, so that the airflow can flow relatively smoothly. It can be understood that under the same pressure conditions, the gas flow velocity in the pipe is negatively correlated with the flow area, that is, the smaller the flow area, the faster the flow velocity. If the air outlet area of ​​the groove cavity 213 is too small, the flow velocity of the airflow will increase accordingly when it flows out, which can easily cause airflow impact and turbulence, which is not conducive to the subsequent flow of airflow from the vent 222 into the aerosol generating rod 6. By setting a first notch 231 that communicates with the air guide groove 211, the flow area can be increased, which helps to alleviate the above-mentioned problems.

[0054] Furthermore, in a specific example, such as Figures 8 to 10 In the example shown, two air guide grooves 211 are provided on the inner wall of the heating base 2, and the two air guide grooves 211 are symmetrically arranged on both sides of the central cavity 212, as shown in the example below. Figure 8 The image shows two symmetrically arranged air guide grooves 211 in the second direction. Accordingly, as shown... Figure 5 In the example shown, two protrusions 23 are symmetrically arranged on the outer wall of the heating base 2. Each of the two protrusions 23 corresponds one-to-one with one of the two air guide grooves 211; that is, a protrusion 23 is provided at a position corresponding to each air guide groove 211 on the outer wall of the heating base 2. When applied in an atomizing device, the directions corresponding to the two protrusions 23 (i.e.,...) can be... Figure 10The second direction shown in the figure is arranged to correspond to the width direction of the housing, so as to make full use of the space of the housing in the width direction and avoid the space occupied by the protrusion 23 from conflicting or interfering with other components in the housing.

[0055] It should be noted that the shapes of the air guide groove 211 and the protrusion 23 in the above embodiments are not limited to the arc-shaped structure in the example. In practical applications, other shapes can also be adopted according to specific design requirements and needs, such as rectangles, triangles, trapezoids or other irregular shapes, as long as they are suitable for airflow. This will not be elaborated further here.

[0056] Furthermore, such as Figure 8 In the example, the inner wall of the stepped groove 13 of the mounting sleeve 1 has a mating groove 131. The shape of the mating groove 131 is adapted to the shape of the protrusion 23 of the heating base 2, and the protrusion 23 extends into the mating groove 131 to serve as an assembly and limiting function.

[0057] In further embodiments of this application, such as Figure 3 , Figure 8 and Figure 10 As shown, in the heating base 2, the heating hole 221 is located at the center of the bottom wall 22 of the cavity, and multiple vent holes 222 are located between the heating hole 221 and the outer edge of the bottom wall 22 of the cavity, and are evenly spaced along the circumferential direction of the heating hole 221, so that the hot airflow can enter the aerosol generating rod 6 relatively uniformly after passing through the multiple vent holes 222. The number of vent holes 222 is not limited to... Figure 8 and Figure 10 The four shown can also be set to other quantities according to actual needs.

[0058] An embodiment of the second aspect of this application provides an atomizing device 300, such as Figure 11 , Figure 12 and Figure 13As shown, the atomizing device 300 includes a housing 3, a heating base device 100 as described in any of the above embodiments, and a heating device 4. The housing 3 serves as the base of the atomizing device 300. In a first direction, one end of the housing 3 has an assembly groove 31 for assembling the heating base device 100. The heating base device 100 is partially disposed in the assembly groove 31 and detachably connected to the housing 3. Specifically, the end of the mounting sleeve 1 of the heating base device 100 away from the insertion port 12 is located inside the assembly groove 31, while the end of the mounting sleeve 1 with the insertion port 12 is located outside the assembly groove 31, facilitating the insertion of the aerosol generating rod 6 by the user during use. The heating device 4 is disposed inside the housing 3 and is disposed in the first direction at the end of the heating base 2 away from the insertion port 12. The heating device 4 has a heating element 41 disposed in the first direction toward the heating base 2, and the heating element 41 extends through the heating hole 221 of the heating base 2 into the heating chamber 21 so that when the aerosol generating rod 6 is contained in the heating chamber 21, the heating element 41 is used to heat the aerosol generating rod 6.

[0059] During use, the air guide groove 211 in the heating chamber 21 is connected to the outside through the first air inlet 16 and the second air inlet 25. When the user performs a suction action through the suction end of the aerosol generating rod 6, the airflow is drawn into the heating chamber 21 under negative pressure and flows through the air guide groove 211 in the first direction to the outside of the bottom wall 22 of the heating chamber 21. At the same time, the airflow is heated in the air guide groove 211 to form a hot airflow. Then, under negative pressure, the hot airflow passes through the vent 222 on the bottom wall 22 of the chamber and enters the interior of the aerosol generating rod 6 to carry the aerosol generated by the atomizing matrix to the suction end of the aerosol generating rod 6.

[0060] The atomizing device 300 in this embodiment allows for sidewall air intake via the first air inlet 16 and the second air inlet 25 on the heating base device 100 when the aerosol generating rod 6 is inserted into the heating chamber 21. The airflow is directed in a first direction towards the outer side of the bottom wall 22 of the heating chamber 21 by the through-hole 211 on the inner sidewall of the heating base 21. As the airflow passes through the through-hole 211, it is heated to form a hot airflow, which then flows into the aerosol generating rod 6 through the vent 222 on the bottom wall 22. This prevents cold air from directly entering the aerosol generating rod 6 and causing a hot-cold clash, thus enhancing the heating effect. Furthermore, there is no need to reserve an air intake gap at the insertion port 12; the insertion port 12 can directly contact the aerosol generating rod 6, enhancing the assembly stability of the aerosol generating rod 6 and preventing it from detaching from the heating chamber during use.

[0061] In further embodiments of this application, such as Figure 13In the example shown, a stepped structure 311 is provided at the opening edge of the mounting groove 31 on the housing 3, and a corresponding protruding structure 15 is provided on the outer wall of the mounting sleeve 1. The protruding structure 15 extends into the stepped structure 311 and abuts against the stepped structure 311 in a first direction. A first air inlet 16 is correspondingly provided with the protruding structure 15 and penetrates the protruding structure 15 laterally. Correspondingly, an air inlet gap 313 is formed between the outer surface of the protruding structure 15 and the side wall of the stepped structure 311, allowing the first air inlet 16 to communicate with the outside through the air inlet gap 313. When the user performs a suction action using the aerosol generating rod 6, the external airflow passes through the air inlet gap 313 and the first air inlet 16 and the second air inlet 25 into the heating chamber. By providing a corresponding air inlet gap 313 between the stepped structure 311 and the protruding structure 15, the first air inlet 16 can be effectively prevented from being blocked, thus avoiding affecting air intake.

[0062] Furthermore, such as Figure 13 As shown, the inner wall of the assembly groove 31 of the housing 3 has a third snap-fit ​​structure 312, and correspondingly, the outer wall of the portion of the mounting sleeve 1 that extends into the assembly groove 31 has a fourth snap-fit ​​structure 142. The fourth snap-fit ​​structure 142 and the third snap-fit ​​structure 312 are correspondingly arranged and form a mutual snap-fit ​​engagement, thereby forming a detachable connection between the mounting sleeve 1 and the assembly groove 31. Specifically, the third snap-fit ​​structure 312 and the fourth snap-fit ​​structure 142 can adopt a mutually cooperating snap-fit ​​protrusion structure, for example... Figure 13 In the example shown, a locking protrusion is provided on each side of the mounting sleeve 1 on the inner wall of the assembly groove 31, and a corresponding locking protrusion is also provided on the outer wall of the mounting sleeve 1. When the mounting sleeve 1 is inserted into the assembly groove 31 along the first direction, the mutual compression between the corresponding locking protrusions generates a slight elastic deformation to form a locking fit. At the same time, the abutment between the protruding structure 15 and the stepped structure 311 in the first direction serves as a limiting action, thereby achieving assembly and fixation. The above-mentioned locking protrusion structure is relatively simple and easy to assemble and disassemble. Of course, the third locking structure 312 and the fourth locking structure 142 can also adopt other structural forms, such as a slot structure and a spring-loaded structure, which can also achieve mutual locking fit.

[0063] Furthermore, such as Figure 11 and Figure 12 In the example, the housing 3 of the atomizing device 300 adopts a flat structure, that is, the width and height dimensions are relatively large, while the thickness dimension is relatively small. Correspondingly, the air guide groove 211 in the heating base 2 is located in the width direction of the housing 3 to make full use of the space of the housing 3 in the width direction and facilitate spatial arrangement.

[0064] Furthermore, such as Figure 13In the example, the heating element 41 can be cylindrical, and one end of the heating element 41 that extends into the heating chamber 21 is set as a spike end so as to facilitate insertion into the aerosol generating rod 6.

[0065] Of course, in practical applications, the heating element 41 is not limited to the above-mentioned cylindrical structure, and can also be set as a sheet, needle or block structure as needed.

[0066] Furthermore, such as Figure 13 In the example shown, the housing 3 of the atomizing device 300 also includes a corresponding support structure 51 for supporting the heating device 4. The support structure 51 has a battery housing 52 for accommodating the power supply battery (not shown) of the heating device 4. The heating device 4 also has a conductive structure 42 connected to the heating element 41, and the conductive structure 42 is electrically connected to the power supply battery. Furthermore, the heating device 4 also has an electronic control element (not shown) corresponding to the power supply battery for controlling the power supply to the heating element 41.

[0067] Furthermore, the atomizing device 300 in this application also has all the beneficial effects of the heating base device 100 in any of the above embodiments, which will not be repeated here.

[0068] 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.
