Description

Technical Field

[0001] This application relates to the field of atomizing equipment technology, specifically to a heating base and an atomizing 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

The base body extends into the stepped groove at the end facing the insertion port and abuts against the bottom wall of the stepped groove.

[0011] In a further embodiment of this application, a sealing protrusion is provided on the outer side wall of the base body. The sealing protrusion is arranged around the circumference of the base body, and the outer side wall of the sealing protrusion abuts against the inner side wall of the mounting sleeve.

However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[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 provided in this application can be used in atomizing equipment to heat and atomize aerosol generating rods. By employing a nested assembly sleeve and base body, a first air inlet hole is provided on the side wall of the assembly sleeve, and a first air guide groove extending in a first direction is provided on the inner side wall of the base body. A second air inlet hole extending laterally is provided within the first air guide groove to achieve lateral air intake. Simultaneously, a second air guide groove communicating with the first air guide groove is provided on the bottom wall of the heating chamber. When applied in atomizing equipment, the heating element of the atomizing equipment is inserted into the heating chamber through heating holes on the bottom wall of the heating chamber, and is heated and atomized inside the aerosol generating rod. The airflow is guided by the first air guide groove to the second air guide groove on the bottom wall of the chamber. At the same time, the airflow is heated in the heating chamber to form a hot airflow, which then flows into the interior of the aerosol generating rod from the end face. This avoids the cold air with a lower temperature directly entering the aerosol generating rod and causing a cold-heat collision. Moreover, the airflow does not flow outward after entering the heating chamber, which helps to enhance the heating effect. In addition, 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 and atomizing device provided in this application with reference to the accompanying drawings.

[0039] The first aspect of this application provides a heating base 100, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the heating base 100 includes an assembly sleeve 1 and a base body 2. The assembly sleeve 1 has an assembly cavity 11 that extends along a first direction. At least one first air inlet 16 is provided on the side wall of the assembly sleeve 1, and the first air inlet 16 communicates with the assembly cavity 11. The base body 2 is disposed within the assembly cavity 11 and is detachably connected to the assembly sleeve 1. When applied to an atomizing device, the assembly sleeve 1 is used for assembly and fixation with the housing of the atomizing device. One end of the assembly cavity 11 in the first direction has an insertion port 12, corresponding to which, such as... Figure 4 , Figure 5 and Figure 6 In the example, the base body 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 base body 2 through the insertion port 12; as shown Figure 4 , Figure 6 As 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, and a heating hole 221 is provided on the bottom wall 22. The heating hole 221 is used for the heating element of the atomizing device to pass through and be inserted into the aerosol generating rod 6 for heating. The inner sidewall of the base body 2 has at least one first air guide groove 211, which extends along a first direction. A second air inlet 25 is provided in the first air guide groove 211, which is laterally penetrating. The second air inlet 25 communicates with the first air inlet 16, allowing external airflow to pass through the first air inlet 16 and the second air inlet 25 sequentially into the heating chamber 21. Inside the heating chamber 21, a second air guide groove 223 is provided on the bottom wall 22, which communicates with the first air guide groove 211. Figures 6 to 7 As shown, when the aerosol generating rod 6 is inserted into the heating chamber 21, the external airflow can still enter the first air guide groove 211 of the base body 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 first air guide groove 211 to the second air guide groove 223 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. After being guided by the second air guide groove 223, the airflow flows to the end face of the aerosol generating rod 6 and is sucked into the interior 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] In this embodiment, the heating base 100, through structural improvements and optimizations, enables sidewall air intake when the aerosol generating rod is assembled into the heating chamber. This is achieved through the first air inlet of the mounting sleeve and the second air inlet of the base body. The airflow is guided to the end face of the aerosol generating rod via the first air guide groove on the inner sidewall of the base body and the second air guide groove on the bottom wall of the chamber. Simultaneously, the airflow is heated to form a hot airflow, which is then drawn into the interior of the aerosol generating rod. This avoids direct cold air entering the aerosol generating rod and causing a hot-cold clash. Furthermore, the airflow does not need to flow to the outside of the heating chamber, allowing for sufficient heating and enhancing the heating effect. Additionally, the heating base 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. This design allows for effective compatibility with existing atomizing devices, simplifies the manufacturing process, and improves the user experience.

[0042] It should be noted that the number of the first air guide groove 211 and the second air guide groove 223 in this embodiment can be one or more. The shape of the first air guide groove 211 and the second air guide groove 223 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 base body 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 first 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 Figures 6 to 8As shown, in the base body 2, the heating cavity 21 includes a central cavity 212 and a recessed cavity 213. On a projection plane perpendicular to the first direction, the central cavity 212 is located at the center of the base body 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 entirely located inside the central cavity 212, or the insertion port 12 coincides with the central cavity 212. In use, as... Figure 6 In the example, when the aerosol generating rod 6 is inserted into the heating chamber 21, it occupies the space of the central cavity 212. The inner wall of the heating chamber 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 first air guiding groove 211 and the central cavity 212. The second air guiding groove 223 on the bottom wall 22 of the cavity communicates with both the recessed cavity 213 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 passes through the recessed cavity 213 in the first direction, flows into the second air guiding groove 223 on the bottom wall 22 of the cavity, and flows into the central cavity 212 under the guidance of the second air guiding groove 223, and then flows into its interior from the end face of the aerosol generating rod 6.

[0045] Furthermore, such as Figure 8 and Figure 9 As shown, on the bottom wall of the cavity, the second air-guiding groove 223 specifically includes a connecting groove 224 and a central groove 225. On the projection plane perpendicular to the first direction, the central groove 225 is located inside the central cavity 212, so that when the aerosol generating rod 6 is inserted into the central cavity 212, the central groove 225 can correspond to the end face of the aerosol generating rod 6; the connecting groove 224 extends laterally, and one end of the connecting groove 224 communicates with the central groove 225, and the other end communicates with the groove cavity 213 formed by the first air-guiding groove 211. Accordingly, on the bottom wall 22 of the cavity, the area excluding the connecting groove 224 and the central groove 225 has a greater thickness in the first direction than the connecting groove 224 and the central groove 225. This is so that when the aerosol generating rod 6 is inserted into the central cavity 212, it acts as a limiter by abutting against the end face of the aerosol generating rod 6, preventing the aerosol generating rod 6 from blocking the connecting groove 224 and the central groove 225. This allows the airflow to flow normally in the connecting groove 224 and the central groove 225, and then flows into the interior of the aerosol generating rod 6 from its end face. The specific shapes of the connecting groove 224 and the central groove 225 are not limited to... Figure 8 The examples in the document can be configured according to specific usage requirements.

[0046] Furthermore, such as Figure 8 and Figure 9In 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 8 In the example shown, on the projection plane perpendicular to the first aspect, the inner wall of the first 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 first 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.

[0047] Furthermore, such as Figure 8 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 first 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 first 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 base body 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.

[0048] In further embodiments of this application, such as Figures 7 to 10 As shown, the outer wall of the base body 2 has a protrusion 23 corresponding to the first air guide groove 211. The protrusion 23 is an arc-shaped structure adapted to the first air guide groove 211, and the protruding direction of the protrusion 23 is consistent with the concave direction of the first air guide groove 211. Furthermore, the wall thickness of the base body 2 remains consistent in the circumferential direction to meet the strength requirements and design and processing requirements of the base body 2, while also satisfying the corresponding heat insulation requirements. It is understood that if the wall thickness of the base body 2 at the location of the first air guide groove 211 is smaller 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 chamber 21. In this embodiment, by providing a protrusion 23 adapted to the first air guide groove 211, the above problems can be effectively alleviated.

[0049] In further embodiments of this application, such as Figures 7 to 10As shown, the inner end of the sleeve 1 near the insertion port 12 has a stepped groove 13, 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 base body 2 facing the insertion port 12. The end of the base body 2 facing the insertion port 12 extends into the stepped groove 13, and the end face of the base body 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.

[0050] 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.

[0051] It should be noted that, as Figure 9 and Figure 10 In the example, when a protrusion adapted to the first air guide groove is provided on the outer side wall of the base body, the inner side 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 base body 2, and the protrusion 23 extends into the mating groove 131 to play the role of assembly and positioning.

[0052] Furthermore, such as Figures 6 to 10 As shown, the outer wall of the base body 2 is also provided with a sealing protrusion 24. The sealing protrusion 24 is arranged around the circumference of the base body 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, and the plurality of first snap-fit ​​structures 241 are spaced apart in the circumference of the base body 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 snap-fitted and fixed to each other to realize the assembly and fixation between the base body 2 and the mounting sleeve 1.

[0053] 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 base body 2. The slot structure is located on the inner side wall of the mounting sleeve 1. When the base body 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 pressure 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.

[0054] It should be noted that in practical applications, the spring-loaded buckle structure and the slot structure can also be interchanged. That is, a slot structure can be set on the outer side wall of the base body 2, while a spring-loaded buckle structure can be set on the inner side wall of the fitting sleeve 1. This can also achieve a snap-fit ​​engagement. The specific setting method and snap-fit ​​principle are similar to those described above, and will not be repeated here.

[0055] Furthermore, in a specific example, such as Figures 6 to 10 In the example shown, two first air guide grooves 211 are provided on the inner sidewall of the base body 2, and the two first air guide grooves 211 are symmetrically arranged on both sides of the central cavity 212, as shown in the example below. Figure 8 The diagram shows two first air guide grooves 211 symmetrically arranged in the second direction. Correspondingly, two protrusions 23 are also symmetrically arranged on the outer wall of the base body 2, with each protrusion 23 corresponding to one of the two first air guide grooves 211. That is, a protrusion 23 is provided on the outer wall of the base body 2 at a position corresponding to each first air guide groove 211. When applied in an atomizing device, the direction corresponding to the two protrusions 23 (i.e., the direction of the two protrusions 23) can be... Figure 8 The second direction shown corresponds 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. In addition, as shown in the figure Figure 8 In the example, on the bottom wall 22 of the cavity, corresponding to the two first air guide grooves 211, the second air guide groove 223 has two connecting grooves 224, which are symmetrically arranged at both ends of the central groove 225, so as to connect the central groove 225 and the groove cavity 213 formed by the corresponding first air guide groove 211.

[0056] It should be noted that the shapes of the first 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.

[0057] In further embodiments of this application, such as Figures 8 to 10 As shown, in the base body 2, the heating hole 221 is located at the center of the bottom wall 22 of the cavity. On a plane perpendicular to the first direction, the central groove 225 of the second air guide groove 223, the central cavity 212 of the heating cavity 21, and the heating hole 221 are coaxially arranged to form a concentric circle. The diameter of the heating hole 221 is smaller than the diameter of the central groove 225, and the diameter of the central groove 225 is smaller than the diameter of the central cavity 212.

[0058] 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 3, a heating base 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 100. The heating base 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 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 user to insert the aerosol generating rod 6 during use. The heating device 4 is disposed inside the housing 3 and is disposed in the first direction at the end of the base body 2 away from the insertion port 12. The heating device 4 has a heating element 41 disposed in the first direction toward the base body 2, and the heating element 41 extends through the heating hole 221 of the base body 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] In use, the first 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 (located outside the heating chamber), the airflow is drawn into the first air inlet 16 under negative pressure, and then flows into the heating chamber 21 through the second air inlet 25. It then flows along the first direction through the first air guide groove 211 to the second air guide groove 223 on the bottom wall 22 of the heating chamber 21. At the same time, the airflow is heated to form a hot airflow. Then, under negative pressure, the hot airflow enters the interior of the aerosol generating rod 6 from the end face 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 side-wall air intake via the first air inlet 16 and the second air inlet 25 on the heating base 100, while the aerosol generating rod 6 is inserted into the heating chamber 21. The airflow is guided along a first direction to the second air inlet on the bottom wall of the heating chamber 21 via the first air guide groove 211 on the inner sidewall of the base body 2. The heated airflow then flows into the aerosol generating rod 6 through the second air guide groove. During the suction process, the airflow remains within the heating chamber, ensuring more thorough heating and preventing cold air from directly entering the aerosol generating rod 6 and causing a hot-cold clash, thus enhancing the heating effect. Furthermore, the side-inlet design eliminates the need for a pre-reserved air intake gap at the insertion port 12, allowing direct contact between the insertion port 12 and the aerosol generating rod 6. This enhances the assembly stability of the aerosol generating rod 6 and prevents it from detaching from the heating chamber during use.

[0061] In further embodiments of this application, such as Figure 13 In the example shown, a stepped structure 311 is provided at the opening edge of the assembly groove 31 on the housing 3. A corresponding protruding structure 15 is provided on the outer wall of the assembly 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 it 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. Correspondingly, the outer wall of the portion of the assembly 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 assembly 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 13In the example, a locking protrusion is provided on each side of the assembly 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 assembly sleeve 1. When the assembly 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 abutting fit between the protruding structure 15 and the stepped structure 311 in the first direction plays a limiting role, 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 first air guide groove 211 in the base body 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 13 In 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 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.
