Abstract
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 heated non-combustible atomizing devices using central heating, a heating column or heating needle is typically inserted into the heating chamber. This allows the heating column or needle to penetrate the aerosol generating rod for heating when it is assembled within the heating chamber. Typically, an air inlet is located at the bottom of the heating chamber, and a corresponding air passage structure is installed within the outer shell of the heating chamber. External cold air flows in through this air passage structure and enters the heating chamber directly without heating, being directly drawn into the aerosol generating rod. This can easily create a hot-cold convection, affecting the heating effect of the aerosol generating rod. Furthermore, the airflow encounters resistance during entry into the heating chamber, requiring significant suction force during use, thus impacting the user experience. Utility Model Content

Moreover, the spiral airflow formed can effectively reduce the resistance during the movement, resulting in stronger airflow power. Users do not need a large suction force when performing suction actions, which is beneficial to improving the user experience. Attached Figure Description

Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. 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.
[0033] 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.
[0034] 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).
[0035] 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.
[0036] The heating base provided in this application can be used in atomizing devices (such as heated non-combustible devices) to heat and atomize aerosol generating rods. By providing a first air passage that spirally extends and connects to an insertion port within the base body, and a corresponding second air passage on the outer end face of the base body's bottom wall, with the second air passage connecting the first air passage and the heating hole on the base bottom wall, when the aerosol generating rod is inserted into the heating chamber within the heating base, the airflow can enter through the insertion port, spiral along the first air passage to the outer end face of the base bottom wall, and then flow back into the heating chamber through the heating hole via the second air passage. When applied in atomizing devices, the heating element of the atomizing device is inserted into the heating chamber through heating holes on the bottom wall of the heating chamber. This heating element heats and atomizes the aerosol generating rod inside the heating chamber. As the airflow moves along the first air passage, it is heated to form a hot airflow. The hot airflow passes through the heating holes and flows into the interior of the aerosol generating rod from the end face of the rod. This avoids the direct entry of cold air into the aerosol generating rod, which would cause a hot-cold clash and enhance the heating effect. Furthermore, the airflow undergoes a spiral motion within the heating chamber, which effectively reduces airflow resistance and enhances airflow power. Users do not need to exert a large suction force when performing inhalation, thus improving the user experience.
[0037] The following describes some embodiments of the heating base and atomizing device provided in this application with reference to the accompanying drawings.
[0038] The first aspect of this application provides a heating base 100, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the heating base 100 includes a base body 1, which has a base side wall 11 and a base bottom wall 12. The base body 1 has a heating cavity 13 formed by the base side wall 11 and the base bottom wall 12. In a first direction, one end of the base body 1 opposite to the base bottom wall 12 has an insertion port 111, which communicates with the heating cavity 13, for inserting an aerosol generating rod into the heating cavity 13 through the insertion port 111. The base bottom wall 12 has a heating hole 121 communicating with the heating cavity 13, for allowing a heating element to pass through when applied to an atomizing device, so that the heating element can heat the aerosol generating rod in the heating cavity 13. The base sidewall 11 has a first air passage 112 on its inner side. The first air passage 112 is spirally arranged in a first direction. One end of the first air passage 112 is connected to the insertion port 111, and the other end of the first air passage 112 passes through the base bottom wall 12 and extends to the outer end face of the base bottom wall 12. A second air passage 122 is correspondingly provided on the outer end face of the base bottom wall 12. The second air passage 122 is connected to the first air passage 112 and the heating hole 121, so that the airflow from the first air passage 112 can flow along the second air passage 122 to the heating hole 121, and then flow back to the heating chamber 13 from the heating hole 121. Figure 4 , Figure 5 and Figure 6 As shown, with the aerosol generating rod 400 inserted into the heating chamber 13, external airflow can still enter the first air passage 112 of the base body 1 through the insertion port 111. When the user performs a suction action on the aerosol generating rod 400, the airflow moves spirally along the first air passage 112 under negative pressure and is heated to form a hot airflow. When the airflow moves to the outer end face of the base bottom wall 12, it flows along the second air passage 122 to the heating hole 121, and then flows back into the heating chamber 13 through the heating hole 121, and is drawn into the interior of the aerosol generating rod 400 through the end face of the aerosol generating rod 400.
[0039] It is understandable that aerosol generating rods need to be heated during use to atomize the atomizing matrix and produce aerosols. 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 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 generating rod, thus lowering the temperature of the atomizing matrix and affecting the atomization effect.
[0040] In this embodiment, the heating base, through structural improvements and optimizations, allows for top air intake via a spirally arranged first air passage within the base body when the aerosol generating rod is assembled inside the heating chamber. The airflow spirals along the first air passage to the outer end face of the base's bottom wall, where it is heated to form a hot airflow. The hot airflow then travels to the heating hole via a second air passage on the base's bottom wall and is drawn into the interior of the aerosol generating rod. This prevents cold air from directly entering the aerosol generating rod and causing a hot-cold clash, thus enhancing the heating effect. Furthermore, the spiral airflow effectively reduces resistance during movement, resulting in stronger airflow power. Users do not need to exert a large suction force when performing suction actions, which improves the user experience.
[0041] In addition, since the heating base 100 has a complete air intake channel, when applied to atomizing equipment, there is no need to set up an additional air channel in the housing of the atomizing equipment, which is beneficial to the overall structural design of the device.
[0042] It should be noted that the number of the first airway 112 and the second airway 122 in this embodiment can be one or more, and the rotation direction of the first airway 112 can be selected according to the actual situation, and is not limited to the clockwise direction shown in the accompanying drawings of this embodiment.
[0043] In further embodiments of this application, such as Figure 7 , Figure 8 and Figure 9 As shown, the first airway 112 specifically includes a first spiral groove 1121, which extends laterally through the inner side of the base sidewall 11. That is, the first spiral groove 1121 is formed by a recess in the inner side of the base sidewall 11, and the opening side of the first spiral groove 1121 faces the interior of the base body 1. In the first direction, the first spiral groove 1121 is spirally arranged. One end of the first spiral groove 1121 extends through the end face of the base sidewall 11 located at one end of the insertion port 111, and the other end of the first spiral groove 1121 extends to the outer end face of the base bottom wall 12 and communicates with the second airway 122. When the aerosol generating rod is inserted into the heating chamber 13, the side wall of the aerosol generating rod 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. External gas can enter the first spiral groove 1121 from the end face of the base side wall 11 and move spirally along the first air passage 112 to the outer end face of the base bottom wall 12, forming a spiral airflow. Compared with the disordered motion state, the airflow is more powerful and can reduce the resistance during the motion process. The airflow is more stable and smooth.
[0044] In practical applications, the cross-sectional shape of the first spiral groove 1121 can be rectangular, semi-circular, triangular, etc., and of course, it can also be set to other shapes suitable for airflow as needed. Figure 7Taking the rectangle shown as an example, the cross-sectional area of the first spiral groove 1121 is 0.2 mm. 2 Up to 5mm 2 Within the range, while meeting the strength requirements of the base sidewall 11, the flow area of the first spiral groove 1121 is maximized.
[0045] Additionally, the number of turns and pitch (i.e., the distance between corresponding points of two adjacent turns in the first direction) of the first spiral groove 1121 can be set according to the dimensions of the base body 1 in the first direction. When the pitch of the first spiral groove 1121 is relatively large, multiple first spiral grooves 1121 can be set as needed to further increase the air intake volume. The multiple first spiral grooves 1121 are circumferentially phase-differentiated to alternate in the first direction and maintain a certain interval to prevent mutual interference. Taking two first spiral grooves 1121 as an example, the two first spiral grooves 1121 are 180° apart circumferentially. In the first direction, another first spiral groove 1121 is provided between two adjacent turns of one first spiral groove 1121.
[0046] It should be noted that the above is only a preferred example of the first air passage 112, and the first air passage 112 is not limited to the form of the first spiral groove 1121 described above. For example, the first air passage 112 can also be configured as a closed hole structure. In another specific example, the first air passage 112 can take the form of a first spiral hole. The first spiral hole is located inside the base sidewall 11, that is, there are no openings on either the inner or outer sides in the lateral direction. The first spiral hole is spirally arranged in a first direction. One end of the first spiral hole penetrates the end face of the base sidewall 11 located at the insertion port 111, and the other end of the first spiral hole extends to the outer end face of the base bottom wall 12 and communicates with the second air passage 122. The first spiral hole forms a spiral air passage, and external gas can enter the first spiral hole from the end face of the base sidewall 11 and move spirally along the first spiral hole to the outer end face of the base bottom wall 12, forming a spiral airflow. By setting the first spiral hole, the airflow intensity can also be increased, and the resistance during the airflow movement can be further reduced, thereby improving the stability of the airflow movement.
[0047] In further embodiments of this application, such as Figure 8 and Figure 9As shown, on the outer end face of the base bottom wall 12, the second air passage 122 specifically includes a second spiral groove 1221. The spiral direction of the second spiral groove 1221 is the same as that of the first air passage 112, so that the airflow can smoothly transition from the first air passage 112 to the second air passage 122. The second spiral groove 1221 is specifically in a state of gradually contracting from the outside to the center, and one end of the second spiral groove 1221 near the edge is connected to the first air passage 112, and the other end of the second spiral groove 1221 is connected to the heating hole 121. After the airflow enters the second air passage 122 from the first air passage 112, it can continue to flow towards the heating hole 121 in a spiral state. By setting the second spiral groove 1221, the airflow can be made to move in a spiral state when flowing on the outer end face of the base bottom wall 12, which can avoid the phenomenon of a sudden change in the direction of airflow movement, thereby reducing airflow impact and disturbance, and at the same time reducing resistance, which is conducive to the smooth and stable flow of airflow towards the heating hole 121.
[0048] In practical applications, when multiple first air passages 112 are provided, multiple second spiral grooves 1221 can also be provided accordingly. Using a similar arrangement, each second spiral groove 1221 is connected to one of the first air passages 112, allowing multiple airflows to move independently and preventing mutual interference. Furthermore, the second spiral grooves 1221 can also adopt a similar structural form to the first air passages 112; for example, their cross-sectional shape can be rectangular, semi-circular, or triangular. Moreover, the width of the second spiral grooves 1221 can be set according to their spatial position on the base bottom wall 12. Figure 9 In the example, the width of the second spiral groove 1221 can be increased in areas with larger spaces, while the width of the second spiral groove 1221 can be decreased near the base sidewall 11 and near the heating hole 121 to adapt to the first air passage 112 and the heating hole 121. The width dimension of the second spiral groove 1221 is gradually changed to keep the airflow movement stable.
[0049] Furthermore, such as Figure 8 , Figure 9 In the example, the second spiral groove 1221 gradually extends towards the inner end face of the base bottom wall 12 along the first direction. The end of the second spiral groove 1221 that communicates with the heating hole 121 is located between the inner end face and the outer end face of the base bottom wall 12 in the first direction, so as to guide the airflow in the second spiral groove 1221, so that the airflow gradually moves towards the heating cavity 13, thereby promoting the air intake at the heating hole 121.
[0050] Furthermore, such as Figure 2 and Figure 9In the example shown, the heating chamber 13 is a cylindrical cavity adapted to fit the shape of the aerosol generating rod. 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 aerosol generating rod's end face. After the heating element extends into the heating chamber 13 through the heating hole 121, it can be inserted into the aerosol generating rod near the center, resulting in more uniform heating. Simultaneously, the central location of the heating hole 121 on the base bottom wall 12 also facilitates the arrangement of the second spiral groove 1221.
[0051] In further embodiments of this application, such as Figure 3 , Figure 8 and Figure 9 As shown, the base body 1 has a connecting port 123 in the base bottom wall 12. The end of the first air passage 112 on the base side wall 11 away from the insertion port 111 extends to the connecting port 123. The end of the second air passage 122 on the outer end face of the base bottom wall 12 also extends to the connecting port 123. The first air passage 112 and the second air passage 122 are connected through the connecting port 123 so that the airflow in the first air passage 112 can pass through the connecting port 123 and flow into the second air passage 122 on the outer end face of the base bottom wall 12. In this configuration, on the projection plane perpendicular to the first direction, the connecting port 123 is located outside the projection plane of the insertion port 111, that is, the connecting port 123 is located on the base bottom wall 12 near the outer edge, corresponding to the base side wall 11. The first air passage 112 extends along the base side wall 11 to the connection point with the base bottom wall 12 and can then connect with the connecting port 123 without changing the extension direction. Correspondingly, the position of the connecting port 123 near the outer edge of the base bottom wall 12 can also reserve more space for the setting of the second air passage 122 to meet the requirements of airflow transition.
[0052] In further embodiments of this application, such as Figures 1 to 6 As shown, the heating base 100 also includes a mounting shell 2. The mounting shell 2 has a mounting cavity 20, and the base body 1 is disposed within the mounting cavity 20 and detachably connected to the mounting shell 2. In a first direction, the mounting cavity 20 has a first opening 21 and a second opening 22 disposed opposite to each other. The insertion port 111 of the base body 1 corresponds to the first opening 21, and the heating cavity 13 of the base body 1 communicates with the first opening 21 for insertion of the aerosol generating rod 400. When applied to an atomizing device, it can be connected and assembled with the housing of the atomizing device via the mounting shell 2. For example... Figure 5In the example, the shape of the first opening 21 is adapted to the aerosol generating rod 400, and the aperture of the first opening 21 is not less than the first threshold value to reserve sufficient opening size for the aerosol generating rod 400 to pass through. When the aerosol generating rod 400 passes through the first opening 21 and is inserted into the heating chamber 13 through the insertion port 111 of the base body 1, there is a certain gap space between the inner edge of the first opening 21 and the base side wall 11 of the aerosol generating rod 400 to form an air intake gap 23. External airflow can enter the first air passage 112 of the base body 1 through the air intake gap 23 to achieve top air intake. The first threshold value can be set according to the size of the aerosol generating rod.
[0053] Furthermore, such as Figures 1 to 3 as well as Figure 5 As shown, on the base body 1, the outer side surface of the base sidewall 11 has a sealing protrusion 113 arranged circumferentially. The sealing protrusion 113 abuts against the inner sidewall of the mounting shell 2 to form a sealed assembly between the base body 1 and the mounting shell 2. Moreover, it can provide lateral support and limit the position, which is beneficial to improving the assembly stability.
[0054] Furthermore, such as Figures 1 to 3 as well as Figure 5 As shown, on the base body 1, there is a first snap-fit structure 114 on the outer side surface of the base sidewall 11, and correspondingly, there is a second snap-fit structure 24 on the inner side wall of the mounting shell 2 that matches the first snap-fit structure 114. The second snap-fit structure 24 and the corresponding first snap-fit structure 114 form a snap-fit engagement to achieve connection and fixation.
[0055] In a specific example, the first snap-fit structure 114 and the second snap-fit structure 24 can be specifically as follows: Figure 5 The spring-loaded structure and the slot structure shown are connected to the end of the sealing protrusion 113 away from the insertion port 111 and maintain a certain gap with the outer side wall of the base body 1. The slot structure is located on the inner side wall of the mounting shell 2. When the base body 1 is inserted into the mounting cavity 20 of the mounting shell 2 along the first direction, the spring-loaded structure can undergo a certain elastic deformation under the compression of the inner side wall of the mounting shell 2. 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.
[0056] 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 of the base sidewall 11, while a spring-loaded structure can be set on the inner sidewall of the mounting shell 2. This can also achieve a snap-fit. The specific setting method and snap-fit principle are similar to those described above, and will not be repeated here.
[0057] Furthermore, such as Figure 5In the example, the mounting shell 2 has a stepped groove 27 at one end near the first opening 21, and the first opening 21 is specifically located on the bottom wall of the stepped groove 27. The shape of the stepped groove 27 is adapted to the shape of the end of the base body 1 where the insertion port 111 is provided. The end of the base body 1 where the insertion port 111 is provided extends into the stepped groove 27, and the end face of the base body 1 abuts against the bottom wall of the stepped groove 27 to limit the base body 1 in the first direction. At the same time, with the cooperation of the first snap-fit structure 114 and the second snap-fit structure 24, the connection and fixation between the base body 1 and the mounting shell 2 are realized.
[0058] In further embodiments of this application, such as Figures 4 to 6 In the example shown, the outer wall of the mounting shell 2 has a third snap-fit structure 25, which allows it to snap into and secure the shell when assembled into the shell of the atomizing device. It should be noted that the third snap-fit structure 25 is not limited to the form of the protruding structure shown in the figure; it can be specifically designed according to the specific matching structure of the shell.
[0059] In further embodiments of this application, such as Figures 4 to 6 In the example, the outer side wall of the mounting shell 2 has a boss structure 26 near the first opening 21. When assembled with the housing of the atomizing device, the boss structure 26 abuts against the housing so that the mounting shell 2 is partially inserted into the housing, while the part of the mounting shell 2 with the first opening 21 is located outside the housing for easy disassembly.
[0060] An embodiment of the second aspect of this application provides an atomizing device 300, such as... Figure 10 , Figure 11 As shown, the atomizing device 300 includes a housing 31, a heating base 100 as described in any of the embodiments of the first aspect, and a heating assembly 32. The housing 31 serves as the base of the atomizing device 300. In a first direction, one end of the housing 31 has an assembly groove 311 for assembling the heating base 100. At least a portion of the heating base 100 is disposed in the assembly groove 311 and is detachably connected to the housing 31. The insertion port of the heating base corresponds to the opening of the assembly groove for inserting an aerosol generating rod. The heating assembly 32 is disposed within the housing 31 and corresponds to the base bottom wall 12 of the base body 1 in the first direction. The heating assembly 32 has a heating element 321 disposed along the first direction towards the base body 1, and the heating element 321 extends through a heating hole 121 on the base bottom wall 12 into a heating chamber 13, so that when the heating chamber 13 contains an aerosol generating rod 400, the heating element 321 heats the aerosol generating rod 400. The size of the heating hole 121 is larger than the size of the heating element 321, so that air intake space can still be reserved when the heating element 321 is inserted into the heating hole 121.
[0061] like Figure 11In the example, during use, the aerosol generating rod 400 is inserted into the heating chamber 13, allowing the heating element 321 to penetrate the interior of the aerosol generating rod 400, thereby heating the atomizing matrix inside the aerosol generating rod 400 to form an aerosol. At this time, the first air passage 112 of the base body 1 is connected to the outside. When the user performs a suction action through the suction end of the aerosol generating rod 400 (the end located outside the heating chamber 13), external air enters the first air passage 112 under negative pressure, and then spirals along the first air passage 112 to the outer end face of the base bottom wall 12, where it is heated to form a hot airflow. The hot airflow then flows through the second air passage 122 to the heating hole 121, and flows back into the heating chamber 13 from the heating hole 121. Under negative pressure, the hot airflow enters the interior of the aerosol generating rod 400 from its end face, carrying the aerosol generated by the atomizing matrix to the suction end of the aerosol generating rod 400.
[0062] The atomizing device 300 in this embodiment allows for top air intake when the aerosol generating rod 400 is inserted into the heating chamber 13. Airflow is supplied through the first air passage 112 and the second air passage 122 of the heating base 100, causing the airflow to spiral and heat up to form a hot airflow. This hot airflow then flows into the aerosol generating rod 400 through the heating hole 121, preventing cold air from directly entering the aerosol generating rod 400 and causing a hot-cold clash, thus enhancing the heating effect. Furthermore, the spiral airflow effectively reduces resistance during movement, resulting in stronger airflow power. Users do not need to exert significant suction force when inhaling, improving the user experience. Additionally, there is no need to add additional air passages to the housing 31 of the atomizing device 300, which is beneficial for the overall structural design.
[0063] The following describes a specific example of the atomizing device 300 of this application in conjunction with the accompanying drawings.
[0064] like Figure 10 and Figure 11 As shown, the heating base 100 of the atomizing device 300 includes a base body 1 and a mounting shell 2. (As indicated...) Figures 4 to 9As shown, the base body 1 is a cylindrical structure with a base side wall 11 and a base bottom wall 12. The base body 1 contains a cylindrical heating cavity 13 formed by the base side wall 11 and the base bottom wall 12. In a first direction, one end of the base body 1 opposite to the base bottom wall 12 has an insertion port 111, which communicates with the heating cavity 13. The base bottom wall 12 has a heating hole 121 communicating with the heating cavity 13. The heating hole 121 is located at the center of the base bottom wall 12 and is coaxially arranged with the heating cavity 13. The inner surface of the base sidewall 11 has a first air passage 112, which specifically includes a spirally arranged first spiral groove 1121. One end of the first air passage 112 passes through the end face of the base sidewall 11 and communicates with the insertion port 111. The other end of the first air passage 112 passes through the base bottom wall 12. A second air passage 122 is correspondingly provided on the outer end face of the base bottom wall 12. The second air passage 122 specifically includes a spirally arranged second spiral groove 1221, and the spiral direction of the second spiral groove 1221 is the same as that of the first spiral groove 1121. The base bottom wall 12 has a connecting opening 123. On a projection plane perpendicular to the first direction, the connecting opening 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 connecting opening 123. One end of the second spiral groove 1221 also extends to the connecting opening 123, and communicates with the first spiral groove 1121 through the connecting opening 123. Specifically, the second spiral groove 1221 gradually contracts from the outside to the inside. The other end of the second spiral groove 1221 communicates with the heating hole 121. In the first direction, the connection between the second spiral groove 1221 and the heating hole 121 is located between the outer end face and the inner end face of the base bottom wall 12. The base body 1 is made of PEEK (Poly ether-ether-ketone) or PI (Polyimide) material, such as... Figure 7 In the example, both the first helical groove 1121 and the second helical groove 1221 have rectangular cross-sections, and the cross-sectional area of the first helical groove 1121 is 0.2 mm. 2 Up to 5mm 2 Within the range.
[0065] like Figures 4 to 6In the example, the mounting shell 2 has a mounting cavity 20, and the base body 1 is disposed within the mounting cavity 20. In a first direction, the mounting cavity 20 has a first opening 21 and a second opening 22 disposed opposite to each other. The insertion port 111 of the base body 1 is correspondingly disposed with respect to the first opening 21, and the heating cavity 13 of the base body 1 communicates with the first opening 21 for the insertion of the aerosol generating rod 400. The mounting shell 2 has a stepped groove 27 at one end near the first opening 21, and the first opening 21 is specifically located on the bottom wall of the stepped groove 27. One end of the base body 1 with the insertion port 111 extends into the stepped groove 27, and the end face of the base body 1 abuts against the bottom wall of the stepped groove 27. Wherein, as... Figure 5 In the example, the shape of the first opening 21 is adapted to the aerosol generating rod 400, and the aperture of the first opening 21 is not less than the first threshold, so as to reserve a sufficient opening size for the aerosol generating rod 400 to pass through.
[0066] like Figure 5 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 mounting shell 2 to form a sealed assembly between the base body 1 and the mounting 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 mounting 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.
[0067] like Figure 10 and Figure 11In the example, a stepped structure 314 is provided at the opening edge of the mounting groove 311 on the housing 31. Two boss structures 26 are correspondingly provided on the outer side wall of the mounting housing 2. When one end of the mounting housing 2 with the second opening 22 is inserted into the mounting groove 311, the boss structure 26 extends into the stepped structure 314 and abuts against the stepped structure 314 in the first direction, so that one end of the mounting housing 2 with the first opening 21 is located outside the mounting groove 311. The outer side wall of the portion of the mounting housing 2 that extends into the mounting groove 311 has two third snap-fit structures 25, and the two third snap-fit structures 25 are symmetrically arranged on both sides of the mounting housing 2. Correspondingly, two fourth snap-fit structures 312 are correspondingly provided on the inner side wall of the mounting groove 311 of the housing 31. The fourth snap-fit structures 312 and the corresponding third snap-fit structures 25 form a mutual snap-fit engagement, thereby forming a detachable connection between the mounting housing 2 and the mounting groove 311. Specifically, the third snap-fit structure 25 and the fourth snap-fit structure 312 adopt a mutually cooperating snap-fit protrusion structure. When the mounting shell 2 is inserted into the assembly groove 311 along the first direction, the mutual compression between the corresponding snap-fit protrusion structures generates a small elastic deformation to form a snap-fit fit. At the same time, the abutment fit between the boss structure 26 and the step structure 314 in the first direction plays a limiting role, thereby realizing assembly and fixation.
[0068] like Figure 11 In the example shown, the heating assembly 32 includes a heating element 321, a conductive structure 322, a power supply device 323, and an electronic control element (not shown in the figure). A support structure 33 corresponding to the heating base 100 is provided inside the housing 31. The heating element 321 is mounted on the support structure 33. Specifically, the heating element 321 has a cylindrical structure, extends towards the heating base 100, and extends into the heating cavity 13 through the heating hole 121. One end of the heating element 321 extending into the heating cavity 13 has a spike to facilitate penetration into the aerosol generating rod 400. The conductive structure 322 is connected to the heating element 321 and is also electrically connected to the power supply device 323, so that the power supply device 323 is electrically connected to the heating element 321 to supply power to the heating element 321, enabling the heating element 321 to generate heat. The electronic control element is electrically connected to the power supply device 323 and is used to perform corresponding control operations on the power supply.
[0069] like Figure 5 , Figure 6 and Figure 11In the example, when the aerosol generating rod 400 is inserted into the heating chamber 13, the heating element 321 penetrates into the interior of the aerosol generating rod 400 to heat the atomizing matrix inside the aerosol generating rod 400 to form an aerosol. When the user performs a suction action through the suction end of the aerosol generating rod 400 (the end located outside the heating chamber 13), external air enters the first spiral groove 1121 through the air inlet gap 23 under negative pressure, and then moves spirally along the first spiral groove 1121 to the outer end face of the base bottom wall 12, where it is heated to form a hot airflow. The hot airflow then flows through the second spiral groove 1221 to the heating hole 121, and flows back into the heating chamber 13 through the heating hole 121. Under negative pressure, the hot airflow enters the interior of the aerosol generating rod 400 from the end face to carry the aerosol generated by the atomizing matrix to the suction end of the aerosol generating rod 400.
[0070] After use, the mounting shell 2 and the base body 1 can be removed together from the assembly slot 311 to facilitate the replacement of the aerosol generating rod 400 and to facilitate the removal of residues generated during heating.
[0071] 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.
[0072] 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.
