[0032] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can also be sequentially adjusted or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing one embodiment, and do not mean that the composition and / or order is necessary.
[0033] 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).
[0034] 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.
[0035] The heating base assembly provided in this application can be used in atomizing devices to heat and atomize aerosol generating rods. By employing a nested mounting shell and a heating base, and providing an air inlet groove extending along a first direction on the inner wall of the heating base, the heating chamber of the heating base can accommodate the aerosol generating rod while allowing airflow to pass through. Correspondingly, heating holes and vent holes are provided on the bottom wall of the heating chamber of the heating base. When applied in an atomizing device, the heating element of the atomizing device is inserted into the heating chamber through the heating holes and inserted into the aerosol generating rod for heating and atomization. The airflow flowing into the heating chamber through the air inlet groove is heated to form a hot airflow, which can flow along the first direction to the outside of the bottom wall of the chamber, and then flow into the aerosol generating rod through the vent holes on the bottom wall of the chamber. 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.
[0036] The following describes some embodiments of the heating base assembly and atomizing device provided in this application with reference to the accompanying drawings.
[0037] An embodiment of the first aspect of this application provides a heating base assembly 100, such as... Figure 1 , Figure 2 , Figure 3 As shown, the heating base assembly 100 includes a mounting shell 1 and a heating base 2. The mounting shell 1 has a mounting cavity 11 that extends through the space in a first direction. The heating base 2 is disposed within the mounting cavity 11 and is detachably connected to the mounting shell 1. When applied to an atomizing device, the mounting shell 1 is used to assemble and fix it to the housing of the atomizing device. One end of the mounting cavity 11 in the first direction has an insertion port 12. Correspondingly, the heating base 2 has a heating cavity 21 that extends through the end facing the insertion port 12. The aerosol generating rod 6 can be inserted into the heating base 2 through the insertion port 12. Figure 2 , Figure 4 and Figure 5As shown, the heating chamber 21 has a bottom wall 22 at the end away from the insertion port 12, which 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 sidewall of the heating base 2 has at least one air inlet groove 211, which extends along a first direction and penetrates both ends of the heating base 2. Figure 4 to Figure 6 As shown, when the aerosol generating rod 6 is inserted into the heating chamber 21, the external airflow can still flow into the air inlet groove 211 of the heating base 2 through the insertion port 12. When the user performs a suction action on the aerosol generating rod 6, the airflow flows along the air inlet 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, it flows back into the heating chamber 21 through the vent hole 222 on 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.
[0038] 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.
[0039] In this embodiment, the heating base assembly 100 improves and optimizes the structure of the heating base. When the aerosol generating rod is inserted into the heating chamber 21, air can be introduced through the insertion port 12 by utilizing the air inlet groove 211 that runs through the inner sidewall of the heating base. The airflow is heated as it passes through the air inlet groove 211 to form a hot airflow, which then flows into the aerosol generating rod through the vent hole 222 on the bottom wall of the groove. This avoids cold air directly entering the interior of the aerosol generating rod and causing a clash between hot and cold air, which is beneficial to enhancing the heating effect.
[0040] Moreover, the structure of the heating base assembly 100 in this embodiment is relatively simple, and there is no need to set up corresponding air channels in the atomizing device. It can be effectively adapted to existing atomizing devices, which is conducive to simplifying the process.
[0041] It should be noted that the number of air intake grooves 211 in this embodiment can be one or more, and the shape of the air intake 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.
[0042] In further embodiments of this application, such asFigure 7 and Figure 8 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 8 In the example, the central cavity 212 is located at the center of the heating base 2 and is entirely inside the insertion port 12. 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 inlet recess 211 and the central cavity 212. The shape of the central cavity 212 is adapted to the shape of the aerosol generating rod 6. In use, when the aerosol generating rod 6 is inserted into the heating cavity 21, it occupies the space of the central cavity 212. The external airflow flows into the recessed cavity 213 corresponding to the air inlet recess 211 through the gap between the insertion port 12 and the side wall of the aerosol generating rod 6, and then passes through the recessed cavity 213 along the 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 hole 222 on the cavity bottom wall 22.
[0043] Furthermore, such as Figure 5 and Figure 8 In the example shown, 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. This allows the inner wall of the central cavity 212 to limit the aerosol generating rod 6 when it is inserted, preventing blockage of the recessed cavity 213. Specifically, on the projection plane perpendicular to the first aspect, the inner wall of the air inlet recess 211 is an arc-shaped surface. This arc-shaped wall connects smoothly with the circular wall of the central cavity 212, resulting in a smoother connection and higher space utilization. The resulting recessed 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 inlet recess 211 also guides the airflow, allowing it to flow more smoothly within the recessed cavity 213 and reducing airflow disturbance compared to other shapes.
[0044] 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 air intake 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 between the inner wall surface of the air intake groove 211 and the boundary of the central cavity 212 ranges from 0.1 mm to 1 mm. 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 0.5 mm.
[0045] In further embodiments of this application, such asFigure 5 , Figure 7 and Figure 8 As shown, the outer wall of the heating base 2 has a protrusion 23 corresponding to the air inlet groove 211. The protrusion 23 is an arc-shaped structure adapted to the air inlet groove 211, and the protruding direction of the protrusion 23 is consistent with the concave direction of the air inlet 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 inlet 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 inlet groove 211, the above problems can be effectively alleviated.
[0046] Furthermore, such as Figure 4 , Figure 6 and Figure 9 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 inlet 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 providing a first notch 231 that communicates with the air intake groove 211, the flow area can be increased, which helps to alleviate the above-mentioned problems.
[0047] Furthermore, in a specific example, such as Figure 5 to Figure 8 In the example shown, two air inlet grooves 211 are provided on the inner sidewall of the heating base 2, and the two air inlet 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 air intake recesses 211 symmetrically arranged in the second direction. Accordingly, as shown... Figure 5In the example shown, two protrusions 23 are symmetrically arranged on the outer wall of the mounting shell 1. Each of the two protrusions 23 corresponds one-to-one with one of the two air inlet grooves 211; that is, a protrusion 23 is provided on the outer wall of the heating base 2 at a position corresponding to each air inlet groove 211. When applied in an atomizing device, the directions corresponding to the two protrusions 23 (i.e., Figure 8 The 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.
[0048] It should be noted that the shapes of the air intake 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.
[0049] In further embodiments of this application, such as Figure 5 , Figure 6 and Figure 9 As shown, the mounting housing 1 has a stepped groove 13 at one end near the insertion port 12, with the insertion port 12 specifically located on the bottom wall of the stepped groove 13. The shape of the stepped groove 13 matches 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. The inner sidewall of the stepped groove 13 has an air passage structure 131 corresponding to the air inlet groove 211 of the heating base 2, so that the insertion port 12 and the groove cavity 213 are connected through the air passage structure 131. When the aerosol generating rod 6 is inserted into the heating chamber 21 through the insertion port 12, there is a certain gap between the insertion port 12 and the sidewall of the aerosol generating rod 6, allowing airflow to flow in through the insertion port 12 and into the groove cavity 213 of the heating base 2 through the air passage structure 131, achieving top air intake.
[0050] In further embodiments of this application, such as Figure 8 and Figure 9 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 9 The four shown can also be set to other quantities according to actual needs.
[0051] In further embodiments of this application, such asFigure 6 , Figure 8 and Figure 9 As shown, the outer wall of the heating base 2 is also provided with a sealing protrusion 24. The sealing protrusion 24 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 shell 1 to seal the mounting cavity 11. 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 heating base 2. Correspondingly, a plurality of second snap-fit structures 14 are provided on the inner wall of the mounting shell 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 shell 1.
[0052] 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 shell 1. When the heating base 2 is inserted into the mounting cavity 11 of the mounting shell 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 shell 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.
[0053] 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 shell 1. 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.
[0054] An embodiment of the second aspect of this application provides an atomizing device 300, such as... Figure 10 , Figure 11 and Figure 12As shown, the atomizing device 300 includes a housing 3, a heating base assembly 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 assembly 100. The heating base assembly 100 is partially disposed in the assembly groove 31 and detachably connected to the housing 3. The end of the mounting shell 1 of the heating base assembly 100 away from the insertion port 12 is located within the assembly groove 31, while the end of the mounting shell 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.
[0055] During use, the air inlet groove 211 in the heating chamber 21 is connected to the outside through the insertion port 12. 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 inlet 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 inlet groove 211 to form a hot airflow. Then, under negative pressure, the hot airflow passes through the vent hole 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.
[0056] Furthermore, such as Figure 10 and Figure 11 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 inlet 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.
[0057] Furthermore, such as Figure 12 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.
[0058] 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.
[0059] Furthermore, such as Figure 12In 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.
[0060] Furthermore, such as Figure 12 In 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 side wall of the mounting housing 1. The protruding structure 15 extends into the stepped structure 311 and abuts against the stepped structure 311 in a first direction. Correspondingly, the portion of the mounting housing 1 that extends into the mounting groove 31 forms a snap-fit with the mounting groove 31 through a corresponding snap-fit structure. For example, the outer side wall of the mounting housing 1 has a first snap-fit protrusion 16, and the inner side wall of the mounting groove 31 has a corresponding second snap-fit protrusion 312. When the mounting housing is inserted into the mounting groove 31, the mutual compression between the first snap-fit protrusion 16 and the second snap-fit protrusion 312 generates a slight elastic deformation to form a snap-fit, facilitating assembly and disassembly.
[0061] With the atomizing device 300 in this embodiment, when the aerosol generating rod is inserted into the heating chamber 21, air can be introduced through the insertion port 12 by utilizing the air inlet groove 211 that runs through the inner side wall of the heating base. When the airflow passes through the air inlet groove 211, it is heated to form a hot airflow, which then flows into the aerosol generating rod through the vent hole 222 on the bottom wall of the chamber. This avoids cold air directly entering the interior of the aerosol generating rod and causing a clash between hot and cold air, which is beneficial to enhancing the heating effect.
[0062] Furthermore, the atomizing device 300 in this application also has all the beneficial effects of the heating base assembly 100 in any of the above embodiments, which will not be repeated here.
[0063] 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.
