Abstract
Description
Technical Field
[0001] This application relates to the field of atomization equipment technology, specifically to a heating base assembly and an atomization device. Background Technology
[0002] Currently, in heated non-combustible atomizing devices using central heating, a heating column or heating needle is typically installed inside the heating chamber. This allows the heating column to penetrate the aerosol generating rod for heating when it is assembled within the chamber. Typically, an air inlet is located at the bottom of the heating chamber, and a corresponding air passage structure is incorporated within the outer shell. 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 confluence, affecting the heating effect of the aerosol generating rod. Furthermore, the airflow encounters resistance during entry into the heating chamber, requiring significant suction and impacting the user experience. Utility Model Content

[0007] In a further embodiment of this application, the second air passage includes a spirally arranged second spiral groove. The spiral direction of the second spiral groove is the same as that of the first air passage. One end of the second spiral groove is connected to the first air passage, and the other end of the second spiral groove gradually contracts toward the center of the bottom wall of the base and is connected to the heating hole.
[0008] In a further embodiment of this application, in a first direction, the bottom wall of the second spiral groove is located between the outer end face and the inner end face of the base bottom wall; wherein, the depth of the second spiral groove is the same; or, in the direction extending toward the heating hole, the depth of the second spiral groove gradually decreases.
[0009] In a further embodiment of this application, the first airway includes a first spiral groove that extends laterally through the inner side of the base sidewall.
[0010] In a further embodiment of this application, the first airway includes a first spiral hole, which is located entirely inside the sidewall of the base.
[0011] In a further embodiment of this application, the cross-sectional area of the first airway is 0.2 mm. 2 Up to 5mm 2 The cross-sectional area of the first airway is the same; or, the cross-sectional area of the first airway gradually decreases along the first direction near the bottom wall of the base.
[0012] In a further embodiment of this application, the outer wall of the mounting sleeve has a third snap-fit structure, which is used to snap and fix with the housing when assembled with the housing of the atomizing device; and / or, the outer wall of the mounting sleeve has a boss structure near the first opening, and the air inlet extends laterally through the boss structure, which is used to abut against the end face of the housing when assembled with the housing of the atomizing device, so that the first opening of the mounting sleeve is located outside the housing.

[0015] According to the heating base assembly in this application, through structural improvements and optimizations, when the aerosol generating rod is assembled in the heating chamber, side air intake can be achieved using the air inlet and side air passage of the mounting sleeve. This allows the airflow to enter the first spirally arranged air passage inside the heating base. The airflow can spiral along the first air passage to the inner end face of the base bottom wall, where it is heated to form a hot airflow. Then, the second air passage on the base bottom wall allows the hot airflow to move to the heating hole and be drawn into the interior of the aerosol generating rod. This avoids cold air directly entering the interior of the aerosol generating rod, preventing a clash between hot and cold air, and thus enhancing the heating effect. Moreover, the spiral airflow effectively reduces resistance during movement, resulting in stronger airflow power. Users do not need a large suction force when performing suction actions, which improves the user experience. Because of the side air intake method, the size of the first opening can be set to match the aerosol generating rod. When the aerosol generating rod is inserted into the heating chamber through the first opening, it can abut against the aerosol generating rod through the inner edge of the first opening, so that the aerosol generating rod remains stable and is prevented from falling off. Moreover, when applied to atomizing equipment, there is no need to set an air channel inside the housing of the atomizing equipment, which is beneficial to the overall structural design of the machine.

[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 assembly provided in this application can be used in atomizing equipment (such as a heated non-combustible device) to heat and atomize an aerosol generating rod. A first air passage, spirally extending and connected to an insertion port, is provided within the heating base. A corresponding second air passage is provided on the inner end face of the base's bottom wall, and the second air passage connects to the first air passage and a heating hole on the base's bottom wall. Correspondingly, an air inlet is provided on the side wall of the mounting sleeve, and a side air passage connected to the first air passage is provided within the mounting sleeve. When the aerosol generating rod is inserted into the heating chamber within the heating base, the airflow entering the mounting sleeve through the air inlet can pass through the side air passage into the first air passage of the heating base, spirally move along the first air passage to the inner end face of the base's bottom wall, then move through the second air passage to the vicinity of the heating hole, and finally enter the interior of the aerosol generating rod. 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, and heats and atomizes the aerosol generating rod inside the heating chamber. As the airflow moves along the first and second air passages, it is heated to form a hot airflow. The hot airflow can flow into the interior of the aerosol generating rod from the end face near the heating holes, so as to avoid the cold air with lower temperature directly entering the aerosol generating rod and causing a cold-heat collision, which helps to enhance the heating effect. Moreover, the airflow moves in a spiral motion in the heating chamber, which can effectively reduce the resistance of the airflow movement and enhance the airflow power. Users do not need a large suction force when performing the suction action, which helps to improve the user experience.
[0037] The following describes some embodiments of the heating base assembly and atomizing device provided in this application with reference to the accompanying drawings.
[0038] An embodiment of the first aspect of this application provides a heating base assembly 100, such as... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the heating base assembly 100 includes a heating base 1 and a mounting sleeve 2. The heating base 1 has a base side wall 11 and a base bottom wall 12, and the heating base 1 has a heating cavity 13 formed by the base side wall 11 and the base bottom wall 12. In a first direction, the heating base 1 has an insertion port 111 at one end opposite to the base bottom wall 12. The insertion port 111 communicates with the heating cavity 13 and is used to insert 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, which is used for 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, which 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 extends to the inner end face of the base bottom wall 12. A second air passage 122 is correspondingly arranged on the inner 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. The mounting sleeve 2 has a mounting cavity 20, and the heating base 1 is disposed in the mounting cavity 20 and detachably connected to the mounting sleeve 2. In the first direction, the mounting cavity 20 has a first opening 21 and a second opening 22 that are arranged opposite to each other. The insertion port 111 of the heating base 1 is correspondingly arranged with the first opening 21, and the heating chamber 13 of the heating base 1 is connected with the first opening 21. In the first direction, a side air passage 271 is provided at the inner edge of the first opening 21. The side air passage 271 communicates with the first air passage 112 at one end of the heating base 1 where the insertion port 111 is provided. The side wall of the mounting sleeve 2 has a through air inlet 23, and in the lateral direction, an air inlet gap 28 is formed between the heating base 1 and the mounting sleeve 2. When applied to an atomizing device, the mounting sleeve 2 can be connected and assembled with the housing of the atomizing device.
[0039] like Figure 1 and Figure 2 As shown, with the aerosol generating rod 400 inserted into the heating chamber 13, external airflow can still enter the mounting chamber 20 through the air inlet 23 of the mounting sleeve 2, and then enter the first air passage 112 of the heating base 1 through the side air passage 271. When the user performs a suction action on the aerosol generating rod 400, the airflow spirals along the first air passage 112 under negative pressure, and is simultaneously heated to form a hot airflow; when the airflow moves to the bottom wall 12 of the base, it flows along the second air passage 122 towards the inner side of the heating chamber near the heating hole 121. Since the heating hole 121 is opposite to the end face of the aerosol generating rod, the airflow can be drawn into the interior of the aerosol generating rod 400 from the end face.
[0040] 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.
[0041] In this embodiment, the heating base assembly 100, through structural improvements and optimizations, enables side air intake via the air inlet 23 and side air passage 271 of the mounting sleeve 2 when the aerosol generating rod 400 is assembled in the heating chamber 13. This allows the airflow to enter the first spirally arranged air passage 112 within the heating base 1. The airflow spirals along the first air passage 112 to the inner end face of the base bottom wall 12, where it is heated to form a hot airflow. Then, the second air passage 122 of the base bottom wall 12 allows the hot airflow to move to the heating hole 121 and be drawn into the interior of the aerosol generating rod 400. This avoids cold air directly entering the interior of the aerosol generating rod, preventing a clash between hot and cold air and enhancing the heating effect. Furthermore, the spiral airflow effectively reduces resistance during movement, resulting in stronger airflow power. Users do not need a large suction force when performing suction actions, which improves the user experience.
[0042] Furthermore, since air does not need to enter through the first opening of the mounting sleeve, the size of the first opening can be set to fit the aerosol generating rod. This allows the aerosol generating rod to abut against the inner edge of the first opening when it is inserted into the heating chamber, ensuring its stability and preventing it from falling off. Moreover, because the heating base assembly has a complete air intake channel, when applied to atomizing devices, there is no need to create an air intake channel inside the atomizing device's housing, which is beneficial for the overall structural design.
[0043] It should be noted that the number of the first air passage 112, the second air passage 122, the air inlet 23 and the side air passage 271 in this embodiment can be one or more, and the rotation direction of the first air passage 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.
[0044] In further embodiments of this application, such as Figure 2 and Figure 3In the example, the mounting sleeve 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 one end of the heating base 1 with the insertion port 111. The end of the heating base 1 with the insertion port 111 extends into the stepped groove 27 and abuts against the inner side wall of the stepped groove 27 in the circumferential direction. The end face of the heating base 1 abuts against the bottom wall of the stepped groove 27, thereby limiting the heating base 1 in the first direction. The side air passage 271 is located on the inner wall surface of the stepped groove 27, such as... Figure 2 and Figure 3 In the example, the side air passage 271 extends from the side wall of the stepped groove 27 to the bottom wall of the groove and communicates with the first air passage 112 on the end face of the heating base 1. The side air passage 271 connects the first air passage 112 with the air inlet 23. After the external gas enters the mounting cavity 20 through the air inlet 23, it can enter the first air passage 112 of the heating base 1 through the side air passage 271. By setting the stepped groove 27, the mounting sleeve 2 and the heating base 1 can be connected in a plug-in assembly, and the mounting sleeve 2 can be used to limit the heating base 1, so that the heating base assembly 100 can be assembled and fixed together with the housing of the atomizing device.
[0045] Furthermore, such as Figures 2 to 5 As shown, on the heating base 1, a sealing protrusion 113 is provided circumferentially on the outer side surface of the base sidewall 11. The sealing protrusion 113 abuts against the inner sidewall of the mounting sleeve 2 to form a sealed assembly between the heating base 1 and the mounting sleeve 2. It also provides lateral support and limiting, which helps to improve assembly stability. In the first direction, the air inlet 23 is correspondingly provided between the sealing protrusion 113 and the stepped groove 27. After the airflow enters the air inlet gap 28 between the mounting sleeve 2 and the heating base 1 through the air inlet, the sealing protrusion 113 can prevent the airflow from flowing towards the second opening 22. The airflow can only enter the first air passage 112 of the heating base 1 through the side air passage 27 to prevent air leakage.
[0046] Among them, such as Figure 2 , Figure 3 As shown, on the heating base 1, the outer side of the sealing protrusion 113 has a first snap-fit structure 114, and correspondingly, the inner side wall of the mounting sleeve 2 has a second snap-fit structure 24 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.
[0047] In a specific example, the first snap-fit structure 114 and the second snap-fit structure 24 can be specifically as follows: Figure 2 and Figure 3The 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 heating base 1. The slot structure is located on the inner side wall of the mounting sleeve 2. When the heating base 1 is inserted into the mounting cavity 20 of the mounting sleeve 2 in the first direction, the spring-loaded structure can undergo a certain elastic deformation under the compression of the inner side wall of the mounting sleeve 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 engagement.
[0048] It should be noted that in practical applications, the spring-loaded structure and the slot structure can be interchanged. That is, a slot structure can be set on the outer side wall of the sealing protrusion 113, while a spring-loaded structure can be set on the inner side wall of the mounting sleeve 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.
[0049] In further embodiments of this application, such as Figure 2 , Figure 4 and Figure 7 As shown, the first air passage 112 specifically includes a first spiral groove 1121. The first spiral groove 1121 laterally penetrates the inner surface of the base sidewall 11, that is, the first spiral groove 1121 is formed by a recess in the inner surface of the base sidewall 11, and the opening side of the first spiral groove 1121 faces the interior of the heating base 1. In the first direction, the first spiral groove 1121 is spirally arranged. One end of the first spiral groove 1121 penetrates 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 inner end face of the base bottom wall 12 and communicates with the second air passage 122. When the aerosol generating rod 400 is inserted into the heating chamber 13, as... Figure 2 As shown, the sidewall of the aerosol generating rod 400 abuts against or maintains a small gap with the inner sidewall of the base sidewall 11. The first spiral groove 1121 forms a spiral air passage, allowing external gas to enter the first spiral groove 1121 from the end face of the base sidewall 11 and move along the spiral air passage to the inner end face of the base bottom wall 12, thus forming a spiral airflow. Compared to the disordered motion state, the airflow is more powerful, which can reduce the resistance during the motion process, and the airflow is more stable and smooth.
[0050] In practical applications, the cross-sectional shape of the first spiral groove 1121 can be rectangular, semi-circular, triangular, etc., or it can be set to other shapes suitable for airflow as needed.
[0051] 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 heating base 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. Multiple first spiral grooves 1121 maintain a certain phase difference in the circumferential direction 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 in the circumferential direction. In the first direction, another first spiral groove 1121 is provided between two adjacent turns of one first spiral groove 1121.
[0052] In further embodiments of this application, such as Figure 7 In the example, the cross-sectional area of the first helical groove 1121 is 0.2 mm. 2 Up to 5mm 2 Within a certain range, the intake flow rate requirement can be met, while the base sidewall maintains a certain thickness to meet the strength design requirements.
[0053] Furthermore, the first helical groove 1121 can be configured as follows: Figure 7 The uniform cross-sectional shape shown means that the cross-sectional area is the same in the extension direction of the first spiral groove 1121 and remains consistent to keep the airflow stable during movement.
[0054] Of course, in practical applications, at least a portion of the first spiral groove 1121 can be configured with different cross-sectional areas according to usage requirements. For example, in one specific example, the cross-sectional area of the first spiral groove 1121 can be set to gradually decrease in the direction extending towards the base bottom wall 12, so as to increase the airflow velocity and enable the airflow to quickly enter the second air passage 122 from the first spiral groove 1121, which is beneficial to promote the movement of the airflow in the second air passage 122 and makes it easier for the airflow to enter the interior of the aerosol generating rod.
[0055] 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, which is located inside the base sidewall 11, that is, no openings are provided on either the inner or outer sides in the lateral direction. The first spiral hole is spirally arranged in a first direction, with one end penetrating the end face of the base sidewall 11 at the insertion port 111, and the other end extending to the inner end face of the base bottom wall 12 and communicating with the second air passage 122. The first spiral hole forms a spiral air passage, allowing external gas to enter the first spiral hole from the end face of the base sidewall 11 and move along the first spiral hole to the inner end face of the base bottom wall 12, forming a spiral airflow. By providing the first spiral hole, the airflow intensity can be increased, and the resistance during airflow movement can be further reduced, thereby improving the stability of airflow movement.
[0056] In further embodiments of this application, such as Figure 2 , Figure 4 and Figure 8 As shown, on the inner 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 inner 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.
[0057] 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 8In 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.
[0058] In further embodiments of this application, such as Figure 2 , Figure 4 and Figure 7 In the example, in the first direction, the bottom wall of the second spiral groove 1221 is located between the inner and outer end faces of the base bottom wall 12. This ensures that when the aerosol generating rod 400 is inserted into the heating chamber 13, the inner end face of the base bottom wall 12 abuts against the end face of the aerosol generating rod 400, while the second spiral groove 1221 is located below the aerosol generating rod 400 and will not be blocked, ensuring smooth airflow. This guides the airflow within the second spiral groove 1221, causing it to gradually move towards the heating hole 121. Furthermore, in the first direction, the depth of the second spiral groove 1221 is uniform; that is, different sections of the second spiral groove 1221 maintain a consistent depth to facilitate airflow stability and manufacturing.
[0059] It should be noted that the depth of the second spiral groove 1221 specifically refers to the distance from the inner end face of the base bottom wall 12 to the bottom wall of the second spiral groove 1221 in the first direction. Of course, in practical applications, the second spiral groove 1221 can also be configured with different depths in different areas according to the needs of use. For example, in a specific example, the depth of the second spiral groove 1221 can be gradually reduced in the direction extending from the second spiral groove 1221 towards the heating hole 121, so that the bottom wall of the second spiral groove 1221 forms a certain slope to guide the airflow and promote the airflow to move towards the aerosol generating rod 400 in the first direction, so as to enter the interior of the aerosol generating rod 400.
[0060] Furthermore, such as Figures 7 to 9 As shown, the heating base 1 has a connecting port 123 in the base bottom wall 12. The end of the first spiral groove 1121 on the base side wall 11 away from the insertion port 111 extends to the connecting port 123. The end of the second spiral groove 1221 on the inner end face of the base bottom wall 12 also extends to the connecting port 123. The first spiral groove 1121 and the second spiral groove 1221 are connected and connected through the connecting port 123.
[0061] Furthermore, such as Figure 2 , Figure 3 and Figure 8In the example shown, the heating chamber 13 is a cylindrical cavity adapted to 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 penetrate into the interior of 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.
[0062] In further embodiments of this application, such as Figures 1 to 3 In the example shown, the outer wall of the mounting sleeve 2 has a third snap-fit structure 25, which allows it to snap into and fix the sleeve to the housing when assembled into the housing of the atomizing device. It should be noted that the third snap-fit structure 25 is not limited to the form of the protruding structure shown in the figure; it can be specifically designed according to the specific matching structure of the housing.
[0063] In further embodiments of this application, such as Figures 1 to 3 In the example, the outer wall of the mounting sleeve 2 has a boss structure 26 near the first opening 21, and the air inlet 23 extends laterally through the boss structure 26. When assembled with the housing of the atomizing device, the boss structure 26 abuts against the housing so that part of the mounting sleeve 2 is inserted into the housing, while the part of the mounting sleeve 2 with the first opening 21 is located outside the housing for easy disassembly.
[0064] 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 assembly 100 as described in any of the embodiments of the first aspect, and a heating component 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 assembly 100. The heating base assembly 100 is partially disposed in the assembly groove 311 and detachably connected to the housing 31. Furthermore, the air inlet 23 on the mounting sleeve 2 communicates with the external atmosphere. The heating component 32 is disposed within the housing 31 and is correspondingly disposed in the first direction to the base bottom wall 12 of the heating base 1. The heating component 32 has a heating element 321 disposed along the first direction toward the heating base 1, and the heating element 321 extends through a heating hole 121 on the base bottom wall 12 into the heating chamber 13, so that when the aerosol generating rod 400 is contained within the heating chamber 13, 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.
[0065] like Figure 2 and Figure 11 In the example, during use, the aerosol generating rod 400 is inserted into the heating chamber 13, so that 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 (located outside the heating chamber 13), external air enters the air intake gap 28 between the mounting sleeve 2 and the heating base 1 through the air inlet under negative pressure, and then enters the first air passage 112 through the side air passage 271. It then spirals along the first air passage 112 to the inner 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 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 atomized matrix to the suction end of the aerosol generating rod 400.
[0066] The atomizing device 300 in this embodiment allows for side air intake via the air inlet 23 of the sleeve 2 in the heating base assembly 100 when the aerosol generating rod 400 is inserted into the heating chamber 13. Airflow is then supplied through the side air passage 271, the first air passage 112, and the second air passage 122, causing the airflow to spiral and heat up to form a hot airflow. This hot airflow then flows into the aerosol generating rod 400 from near 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 performing inhalation, improving the user experience. The housing 31 of the atomizing device 300 does not require additional air passages, which is beneficial for the overall structural design. In addition, since a side air intake method is adopted, the size of the first opening 21 of the mounting sleeve 2 can be set to be compatible with the aerosol generating rod 400, so that after the aerosol generating rod 400 is inserted into the heating chamber 13, the outer wall can abut against the inner edge of the first opening 21, so as to use the friction force to limit the aerosol generating rod 400 and prevent the aerosol generating rod 400 from falling off.
[0067] The following describes a specific example of the atomizing device 300 of this application in conjunction with the accompanying drawings.
[0068] like Figure 9 and Figure 10 As shown, the heating base assembly 100 of the atomizing device 300 specifically includes a heating base 1 and a mounting sleeve 2. For example... Figures 1 to 8As shown, the heating base 1 has a cylindrical structure with a base side wall 11 and a base bottom wall 12. The heating base 1 contains a cylindrical heating cavity 13 formed by the base side wall 11 and the base bottom wall 12. The size of the heating cavity 13 is adapted to the aerosol generating rod 400. In the first direction, the heating base 1 has an insertion port 111 at one end opposite to the base bottom wall 12, and the insertion port 111 communicates with the heating cavity 13. A heating hole 121 communicating with the heating cavity 13 is provided on the base bottom wall 12. 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 penetrates the end face of the base sidewall 11 and communicates with the insertion port 111, while the other end of the first air passage 112 penetrates the base bottom wall 12. A second air passage 122 is correspondingly provided on the inner 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 second spiral groove 1221 is in a state of gradually contracting from the outside to the center. The other end of the second spiral groove 1221 extends to the side edge of the heating hole 121 and 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 bottom wall 12 has a communication port 123. One end of the first spiral groove 1121 away from the insertion port 111 extends to the communication port 123. One end of the second spiral groove 1221 also extends to the communication port 123 and communicates with the first spiral groove 1121 through the communication port 123.
[0069] The heating base 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.
[0070] like Figures 1 to 3In the example, the mounting sleeve 2 has a mounting cavity 20, and the heating base 1 is disposed within the mounting cavity 20. In a first direction, the mounting cavity 20 has a first opening 21 and a second opening 22 disposed opposite to each other. The insertion port 111 of the heating base 1 is correspondingly disposed with respect to the first opening 21, and the heating cavity 13 of the heating base 1 communicates with the first opening 21. The mounting sleeve 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 heating base 1 with the insertion port 111 extends into the stepped groove 27, and the end face of the heating base 1 abuts against the bottom wall of the stepped groove 27. The inner wall surface of the stepped groove 27 has a side air passage 271, such as... Figure 2 In the example, the side air passage 271 extends from the side wall of the stepped groove 27 to the bottom wall of the groove and communicates with the first air passage 112 on the end face of the heating base 1. The shape of the first opening 21 is adapted to the aerosol generating rod 400. When the aerosol generating rod 400 is inserted into the heating chamber 13 through the first opening 21, the outer side wall of the aerosol generating rod 400 abuts against the inner edge of the first opening 21 to limit the aerosol generating rod 400 by means of friction.
[0071] like Figure 2 In the example, the outer side surface of the base sidewall 11 has a circumferentially arranged sealing protrusion 113, which abuts against the inner sidewall of the mounting sleeve 2 to form a sealed assembly between the heating base 1 and the mounting sleeve 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 sleeve 2 has two second snap-fit structures 24, which engage with the corresponding first snap-fit structures 114 to achieve a fixed connection. Specifically, the first snap-fit structure 114 adopts a spring-loaded structure, and the second snap-fit structure 24 adopts a slot structure. The side wall of the mounting sleeve 2 has a laterally penetrating air inlet 23, and the air inlet 23 is located between the sealing protrusion 113 and the stepped groove 27. An air inlet gap 28 corresponding to the air inlet 23 is formed between the mounting sleeve 2 and the heating base 1, so that the side air passage 271 is connected to the air inlet 23 through the air inlet gap 28.
[0072] like Figure 2 , Figure 9 and Figure 10In the example, a mounting groove 311 is provided at the top of the housing 31, and a stepped structure 314 is provided at the opening edge of the mounting groove 311. Two boss structures 26 are correspondingly provided on the outer side wall of the mounting sleeve 2. When the end of the mounting sleeve 2 with the second opening 22 is inserted into the mounting groove 311, the boss structure 26 extends into the stepped structure 314 and abuts against the stepped structure 314 in the first direction, so that the end of the mounting sleeve 2 with the first opening 21 is located outside the mounting groove 311. The air inlet 23 penetrates the boss structure 26 laterally, and the side wall of the stepped structure 314 is provided with a stepped air passage 3141 opposite to the air inlet 23, so that the external airflow can smoothly enter the air inlet 23. The outer wall of the portion of the mounting sleeve 2 that extends into the assembly groove 311 has two third snap-fit structures 25, which are symmetrically arranged on both sides of the mounting sleeve 2. Correspondingly, the inner wall of the assembly groove 311 of the housing 31 has two fourth snap-fit structures 312. The fourth snap-fit structures 312 and the corresponding third snap-fit structures 25 form a snap-fit engagement, thereby creating a detachable connection between the mounting sleeve 2 and the assembly groove 311. Specifically, the third snap-fit structures 25 and the fourth snap-fit structures 312 adopt a mutually cooperating snap-fit protrusion structure. When the mounting sleeve 2 is inserted into the assembly groove 311 along the first direction, the mutual compression between the corresponding snap-fit protrusion structures generates a slight elastic deformation to form a snap-fit engagement. At the same time, the abutment engagement between the boss structure 26 and the step structure 314 in the first direction plays a limiting role, thereby achieving assembly fixation.
[0073] like Figure 10 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 assembly 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 assembly 100, and extends into the heating cavity 13 through the heating hole 121. One end of the heating element 321 extending into the heating cavity 13 has a spike to facilitate penetration into the aerosol generating rod 400. The conductive structure 322 is connected to the heating element 321 and electrically connected to the power supply device 323, so that the power supply device 323 is electrically connected to the heating element 321 to supply power to the heating element 321, enabling the heating element 321 to generate heat. The electronic control element is electrically connected to the power supply device 323 and is used to perform corresponding control operations on the power supply.
[0074] like Figures 2 to 4 and Figure 10In 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 23 and the side air passage 271 under negative pressure, and then spirals along the first spiral groove 1121 to the inner 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.
[0075] After use, the mounting sleeve 2 and the heating base 1 can be removed from the assembly slot 311 together to facilitate the replacement of the aerosol generating rod 400 and to facilitate the removal of residues generated during heating.
[0076] The atomizing device 300 in this application has all the beneficial effects of the heating base assembly 100 in any of the above embodiments, which will not be repeated here.
[0077] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention.
