This is to avoid obscuring the core parts of the present application with excessive description.

[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] The aerosol generating device provided in this application can be assembled with a power supply component to form a complete aerosol generating equipment. The power supply component provides electrical energy to the aerosol generating device to heat the aerosol matrix and generate aerosols. The aerosol generating device is a liquid-storage type, internally containing a liquid storage chamber for storing the aerosol matrix and a gas guiding chamber for guiding gas into the atomizing core assembly. A first sealing element disposed inside the housing separates the liquid storage chamber and the gas guiding chamber. The first sealing element has a first sealing protrusion and a second sealing protrusion arranged laterally opposite each other, respectively sealingly engaging with the upper housing and the housing base, so that a single sealing element simultaneously seals both the upper housing and the housing base.

[0036] The following describes some embodiments of the aerosol generating apparatus and aerosol generating equipment provided in this application, with reference to the accompanying drawings.

[0037] One embodiment of this application provides an aerosol generating device 100, such as... Figure 1 , Figure 2 and Figure 3 As shown, the aerosol generating device 100 includes a housing 1, a first sealing element 2, and an atomizing core assembly 3. The housing 1 includes a separate upper housing 11 and a housing base 12. The first sealing element 2 and the atomizing core assembly 3 are both disposed within the upper housing 11. The housing base 12 is detachably connected to the bottom of the upper housing 11 to facilitate the assembly of internal components. Figure 3 , Figure 4 and Figure 5 As shown, in the upper housing 11, the outer side wall of the first sealing member 2 has a first sealing protrusion 23, which extends circumferentially and seals with the inner side wall of the upper housing 11; the inner side wall of the first sealing member 2 has a second sealing protrusion 241, which extends circumferentially and abuts against the portion of the housing base 12 that extends into the interior of the upper housing 11, thereby forming a sealing fit with the housing base 12. The top of the upper housing 11 has a suction nozzle 111, which divides the internal space of the housing 1 into a liquid storage chamber 13 and a gas guiding chamber 14 by the first sealing member 2. The liquid storage chamber 13 is located between the first sealing member 2 and the suction nozzle 111, and the gas guiding chamber 14 is located between the first sealing member 2 and the housing base 12. The atomizing core assembly 3 is disposed in the liquid storage chamber 13, and one end of the atomizing core assembly 3 is connected to the mouthpiece 111, while the other end passes through the first sealing member 2 and communicates with the air guide chamber 14. The atomizing core assembly 3 is used to heat the aerosol matrix flowing into the atomizing core assembly 3 from the liquid storage chamber 13, so that the aerosol matrix is ​​atomized to generate aerosol. The gas in the air guide chamber 14 can enter the interior of the atomizing core assembly 3 through the first sealing member 2 to mix with the generated aerosol and drive the aerosol to flow towards the mouthpiece 111.

[0038] Among them, such as Figure 4 and Figure 5In the example, the first sealing protrusion 23 and the second sealing protrusion 241 of the first seal 2 are arranged opposite each other in the lateral direction. When the housing base 12 and the upper housing 11 are assembled in place, the part of the housing base 12 that extends into the upper housing 11 abuts against the second sealing protrusion 241, while the first sealing protrusion 23 abuts against the inner sidewall of the upper housing 11. Thus, the first seal 2 is squeezed from both the inner and outer sides in the lateral direction, so that the upper housing 11 and the housing base 12 can form a tight fit with the first seal 2 to enhance the sealing performance. At the same time, the lateral pressure and frictional resistance of the contact surface can be used to keep the housing base 12 stable.

[0039] It should be noted that the first sealing element 2 can be made of a flexible material, such as silicone, so that the first sealing protrusion 23 and the second sealing protrusion 241 can undergo a certain elastic deformation when compressed, thereby meeting the dynamic assembly requirements of the housing base 12 and also meeting the sealing requirements. Furthermore, the number, shape, and size of the first sealing protrusion 23 and the second sealing protrusion 241 are not limited to the examples shown in the figure and can be set according to specific usage needs.

[0040] It is understandable that common aerosol generating equipment usually requires corresponding seals for the upper shell and the shell base, and the large number of seals increases the assembly difficulty and the complexity of the assembly process.

[0041] The aerosol generating device 100 in this embodiment, through structural improvements and optimizations, can utilize a single sealing element to set an inner and outer opposing first sealing protrusion 23 and a second sealing protrusion 241 to form a sealing fit with the upper housing 11 and the housing base 12, thereby improving the sealing effect, correspondingly reducing the number of sealing elements, which helps to simplify the complexity of assembly operations, reduce assembly difficulty, and improve overall production efficiency.

[0042] In further embodiments of this application, such as Figure 4 , Figure 5 and Figure 6As shown, in the aerosol generating device 100, the bottom of the first sealing member 2 has an upper air guide groove 24, and the top of the housing base 12 has a lower air guide groove 125. The lower air guide groove 125 corresponds to the upper air guide groove 24 and forms an air guide cavity 14. The second sealing protrusion 241 is located on the inner wall of the upper air guide groove 24. The lower air guide groove 125 extends into the upper air guide groove 24, and its outer wall abuts against the second sealing protrusion 241 to form a sealing fit inside the upper air guide groove 24. Through the cooperation of the upper air guide groove 24 and the lower air guide groove 125, the first sealing member 2 can simultaneously form a sealing fit with both the upper housing 11 and the housing base 12. Furthermore, the second sealing protrusion 241 inside the upper air guide groove 24 corresponds to the first sealing protrusion 23 on the outer side, creating compression on both the inner and outer sides, which further improves the sealing performance.

[0043] Furthermore, in one embodiment, such as Figures 3 to 5 In the example, at least two first sealing protrusions 23 are provided on the outer side wall of the first seal 2. In the height direction, the at least two first sealing protrusions 23 are spaced apart and extend along the circumference of the first seal 2 to form a multiple sealing fit with the inner side wall of the upper housing 11 in the height direction. Correspondingly, one or more second sealing protrusions 241 can also be provided on the inner side wall of the upper air guide groove 24. The specific number can be set according to the actual use needs. Since the upper air guide groove 24 is located at the bottom of the first seal 2 and the space is limited, the second sealing protrusions 241 are relatively closer to the bottom of the first seal 2. Therefore, the second sealing protrusions 241 are arranged opposite to the first sealing protrusions 23 near the bottom of the first seal 2, which facilitates spatial arrangement.

[0044] It should be noted that when two or more second sealing protrusions 241 are provided on the inner sidewall of the upper air guide groove 24, the different second sealing protrusions 241 are spaced apart in the height direction, and the same number of first sealing elements 2 are provided on the outer side of the first sealing element 2, and each second sealing protrusion 241 is provided with a first sealing element 2 protrusion on the outer side, so that the upper housing 11 and the housing base 12 can press the first sealing protrusion 23 and the second sealing protrusion 241 of the same height in the lateral direction, so that the contact fit is tighter.

[0045] Furthermore, in a specific example, such as Figure 4 and Figure 5 In the example, the second sealing protrusion 241 located inside the upper air guide groove 24 and the corresponding first sealing protrusion 23 located on the outer side wall of the first seal 2 are directly opposite each other in the height direction, that is, their heights are exactly the same. Therefore, under the compression of the upper shell 11 and the shell base 12, the internal and external pressures in the lateral direction are directly opposite, and the force is relatively balanced.

[0046] Of course, in practical applications, the second sealing protrusion 241 and the first sealing protrusion 23 can be configured to have a certain height difference in the height direction, but the height difference is within an acceptable small range, such as the height difference is within the range of 0.1mm to 0.5mm, so as to reduce the requirements for the machining accuracy of the inner and outer sides to a certain extent without affecting the sealing effect, thereby reducing the manufacturing cost.

[0047] In further embodiments of this application, such as Figures 4 to 7 As shown, a liquid-absorbing column 242 is also provided in the upper air guide groove 24 of the first sealing member 2. The liquid-absorbing column 242 has a hollow structure and extends along the height direction into the lower air guide groove 125 of the housing base 12. A through first opening 2421 is opened on the bottom surface of the liquid-absorbing column 242, which can generate capillary adsorption of the condensate in the lower air guide groove 125, so that the adsorbed condensate is contained inside the liquid-absorbing column 242, thereby reducing the accumulation of condensate in the lower air guide groove 125 and helping to reduce the possibility of condensate leakage. The size of the liquid-absorbing column 242 can be reasonably set according to the capillary effect. For example, the outer diameter of the liquid-absorbing column 242 can be set to 1.2 mm, and the inner diameter (diameter of the first opening 2421) can be set to 0.8 mm to generate the required capillary adsorption effect. To increase the liquid absorption capacity, multiple liquid absorption columns 242 can be set. The positions of the multiple liquid absorption columns 242 can be set according to the structural form in the upper air guide groove 24 to avoid interference with other structures.

[0048] By setting up the liquid absorption column 242 to absorb condensate, it can replace the liquid absorption cotton and other structures commonly used in existing aerosol generation equipment, thereby further reducing the space occupied in the air guide cavity 14, which is conducive to saving space. Moreover, the liquid absorption column 242 is connected to the first sealing element 2 as a whole, which can simplify the assembly process of liquid absorption cotton and other structures, and can also eliminate the structure used to fix the liquid absorption cotton.

[0049] Of course, in practical applications, both the liquid-absorbing column 242 and the liquid-absorbing cotton can be set up simultaneously as needed.

[0050] Furthermore, in one embodiment, such as Figure 6 , Figure 7 and Figure 8 In the example shown, a second opening 2422 is provided on the side wall of the suction column 242 near the bottom. The second opening 2422 extends along the height direction to the bottom surface of the suction column 242 and communicates with the first opening 2421. The suction column 242 can simultaneously adsorb condensate through the first opening 2421 on the bottom surface and the second opening 2422 on the side wall, thereby adapting to condensate at different liquid levels and further improving its adsorption capacity.

[0051] The first opening 2421 can also be configured with a diameter slightly larger or slightly smaller than the inner diameter of the suction column 242, to effectively adsorb condensate from the housing. The number of second openings 2422 can be one or more, for example... Figure 7 The two second openings 2422 shown are symmetrically arranged on both sides of the suction column 242; the shape of the second openings 2422 is not limited to... Figure 7 The straight line shape shown can also be other shapes; the width and height of the second opening 2422 can be set according to the usage requirements.

[0052] Furthermore, in one example, such as Figures 5 to 8 In the example shown, a conductive mounting boss 122 is provided in the lower air guide groove 125 of the housing base 12. The conductive mounting boss 122 protrudes upward along the height direction, and a conductive mounting hole is opened in the conductive boss, which is through along the height direction. A conductive element 123 is provided at the bottom of the housing base 12, and part of the conductive element 123 passes through the conductive mounting hole and extends into the air guide cavity 14. Correspondingly, there are multiple liquid suction columns 242. Among them, a portion of the liquid suction columns 242 corresponds to the conductive mounting boss 122, and the bottom of the liquid suction column 242 extends to the top of the conductive mounting boss 122 to absorb the condensate on the conductive mounting boss 122; another portion of the liquid suction columns 242 extends directly to a position close to the bottom wall of the lower air guide groove 125 to absorb the condensate in the lower air guide groove 125. With the above settings, the condensate at different positions in the lower air guide groove 125 can be adsorbed by the liquid suction columns 242 of different heights, which can further expand the condensate adsorption range and further reduce the possibility of leakage.

[0053] Furthermore, in one example, such as Figure 4 , Figure 6 and Figure 7 As shown, the upper air guide groove 24 is provided with multiple liquid suction columns 242. These columns are spaced apart in a horizontal direction perpendicular to the height, with at least two columns having a gap between 0.6 mm and 1.2 mm. This creates a capillary gap, which can adsorb and store condensate through capillary action, achieving a function similar to that of the liquid suction columns 242. This arrangement not only allows for the adsorption and containment of condensate within the internal space of the liquid suction columns 242 but also utilizes the gaps between adjacent columns, further enhancing the overall condensate adsorption capacity and thus improving leak-proof performance.

[0054] It should be noted that the liquid absorption column 242 is not limited to the cylindrical structure shown in the figure, and can also be set to other structural forms as needed, such as square column or elliptical column.

[0055] In further embodiments of this application, such as Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the housing base 12 has an air inlet duct 121 extending through the height direction, and the air inlet duct 121 extends into the air guide cavity 14 to form a boss-like structure. Correspondingly, the first sealing member 2 has an air guide hole 21 extending through the height direction. The end of the air guide hole 21 facing the liquid storage cavity 13 is sealed and connected to the atomizing core assembly 3, so that the air guide cavity 14 is connected to the atomizing core assembly 3. External air can enter the air guide cavity 14 through the air inlet duct 121, and then enter the interior of the atomizing core assembly 3 through the air guide hole 21 to mix with the aerosol generated by atomization inside the atomizing core assembly 3. The first sealing element 2 has a baffle structure 22 at its bottom, located at the edge of the air guide hole 21. The air guide hole 21 and the air intake passage 121 are separated on both sides of the baffle structure 22, and the baffle structure 22 laterally blocks the top of the air intake passage 121 to prevent condensate from entering the air intake passage 121. When condensate enters the air guide cavity 14 through the air guide hole 21, the baffle structure 22 prevents the condensate from directly contacting the top of the air intake passage 121, and guides the condensate downwards, thus preventing condensate from entering the air intake passage 121 and causing leakage. It should be noted that there can be one or more air intakes, and correspondingly, a baffle structure 22 is provided between each air intake passage 121 and the air guide hole 21. The baffle structure 22 can be designed as follows: Figure 7 and Figure 9 The arc-shaped plate shown, or the baffle structure 22, can also adopt other structural forms suitable for blocking condensate.

[0056] An embodiment of the second aspect of this application provides an aerosol generating device 500, such as... Figure 11 and Figure 12 As shown, the aerosol generating device 500 includes the aerosol generating apparatus 100 and the power supply component 510 as described in any of the embodiments of the first aspect. The power supply component 510 is assembled and connected to the housing 1 of the aerosol generating apparatus 100, and is electrically connected to the atomizing core assembly 3 of the aerosol generating apparatus 100 to supply power to the atomizing core assembly 3, so that the atomizing core assembly 3 can heat up when powered on, so that the aerosol matrix is ​​heated and atomized to form an aerosol.

[0057] It should be noted that the connection method between the power supply component 510 and the aerosol generating device 100 is not limited to... Figure 11 and Figure 12The example shown can be modified to use other connection methods as needed. Additionally, the aerosol generator 100 and power supply component 510 can be detachably connected, allowing users to disassemble and reassemble them as needed to easily replace the aerosol generator 100 storing different flavored aerosol bases. Alternatively, the aerosol generator 100 and power supply component 510 can be a non-detachable integrated structure, depending on specific usage requirements.

[0058] The following describes specific examples of the aerosol generation equipment of this application with reference to the accompanying drawings.

[0059] like Figures 1 to 12 As shown, the power supply component 510 of the aerosol generating device 500 includes a power supply housing 511, a battery 512, and a corresponding electronic control board 513; the battery 512 and the electronic control board 513 are both located in the power supply housing 511, and the battery 512 is electrically connected to the electronic control board 513; the power supply housing 511 is detachably connected to the bottom of the housing 1 of the aerosol generating device 100, for example, by means of a buckle or magnetic attachment, and can be disassembled and assembled as needed.

[0060] like Figure 4 , Figure 5 as well as Figure 12 As shown, the bottom of the housing base 12 of the aerosol generating device 100 has a conductive element 123. One end of the conductive element 123 passes through a conductive hole in the conductive mounting boss 122 and extends to the upper air guide groove 24 at the bottom of the first sealing member 2, and is connected to the pin structure of the atomizing core assembly 3; the other end of the conductive element 123 is located on the bottom surface of the housing base 12. The portion of the conductive element 123 that passes through the conductive mounting boss 122 is a columnar structure, while the portion of the conductive element 123 located on the bottom surface of the housing base 12 is a sheet-like structure. Correspondingly, the electronic control board 513 of the power supply assembly 510 is correspondingly disposed on the top of the battery 512 and abuts against the conductive element 123 of the aerosol generating device 100 through a corresponding electrical connection structure, thereby forming an electrical connection between the power supply assembly 510 and the atomizing core assembly 3, and controlling the power supply state between the battery 512 and the atomizing core assembly 3 through the electronic control board 513.

[0061] like Figure 3 , Figure 4 and Figure 12In the example shown, the atomizing core assembly 3 includes an atomizing cover 31, a liquid absorption structure 32, and an atomizing core 33. The top of the first sealing member 2 has an atomizing core mounting groove 25, and an air guide hole 21 is located within the atomizing core mounting groove 25. The bottom of the atomizing cover 31 extends into the atomizing core mounting groove 25 on the first sealing member 2 and is sealed against the inner wall of the atomizing core mounting groove 25, allowing the atomizing cover 31 to communicate with the air guide cavity 14 through the air guide hole 21. The liquid absorption structure 32 is a cylindrical structure, and the atomizing core 33 is disposed on the inner wall of the liquid absorption structure 32. The atomizing core 33 and the liquid absorption structure 32 are disposed inside the atomizing cover 31. The top of the atomizing cover 31 is a tubular structure that extends along its height into the mouthpiece 111, forming a sealed connection with the mouthpiece 111 through the second sealing member 4. A liquid inlet is provided on the side wall of the atomizing cover 31, allowing the aerosol matrix in the liquid storage chamber 13 to enter the interior of the atomizing cover 31 through the liquid inlet and be adsorbed into the liquid absorption structure 32. The aerosol matrix contacts the atomizing core 33 through the liquid absorption structure 32. When the atomizing core 33 is energized, it heats and atomizes the aerosol matrix. The atomizing core 33 has two pin structures that extend downwards and pass through the first sealing member 2 into the air guiding chamber 14. The portion of the pin structure extending into the air guiding chamber 14 is laterally bent and extends into the corresponding conductive assembly groove 26 in the upper air guiding groove 24. The corresponding conductive member 123 also extends into the conductive assembly groove 26 to abut against the corresponding pin structure. The bottom surface of the housing base 12 has a groove structure communicating with the conductive hole. The sheet-like structure of the conductive member 123 is located in this groove structure to facilitate contact with the electrical connector of the power supply component 510 and form an electrical connection. The power supply housing 511 is a non-enclosed structure, allowing external air to enter the air intake duct 121 on the housing base 12 through the power supply housing 511, and then enter the atomizing cover 31 through the air guide hole 21 to mix with the aerosol generated by the heating of the atomizing core 33, and drive the aerosol to flow towards the mouthpiece 111.

[0062] like Figures 3 to 5In the example, the upper air guide groove 24 at the bottom of the first seal 2 and the lower air guide groove 125 at the top of the housing base 12 are inserted and fitted together to form an air guide cavity 14. At least two first sealing protrusions 23 are provided on the outer side wall of the first seal 2, spaced apart in the height direction and extending circumferentially along the first seal 2. Correspondingly, a second sealing protrusion 241 is provided on the inner side wall of the upper air guide groove 24, extending circumferentially, and directly facing a first sealing protrusion 23 located near the bottom on the outer side wall of the first seal 2 in the height direction. Both the first sealing protrusion 23 and the second sealing protrusion 241 are in the form of convex ridges. The lower air guide groove 125 is inserted into the upper air guide groove 24, and the outer side wall of the lower air guide groove 125 abuts against the second sealing protrusion 241 to form a sealing fit. The inner side wall of the upper housing 11 abuts against the first sealing protrusion 23 to form a sealing fit. The first sealing element 2 forms an internal and external seal with the upper housing 11 and the housing base 12, and the upper housing 11 and the lower air guide groove 125 are squeezed by the outer and inner sides of a set of first sealing protrusions 23 and second sealing protrusions 241 that are directly opposite each other, thereby forming a tight fit.

[0063] like Figure 4 , Figure 6 as well as Figure 9 and Figure 10 As shown, the upper air guide groove 24 of the first sealing member 2 is provided with a liquid injection hole 27, and the lower air guide groove 125 of the housing base 12 is provided with a corresponding liquid injection plug 124 extending along the height direction. The liquid injection hole 27 is connected to the liquid storage chamber 13, and the liquid injection plug 124 extends into the corresponding liquid injection hole 27 to seal the liquid injection hole 27. The housing base 12 can be separated from the upper housing 11 as needed so that the liquid injection plug 124 can be removed from the liquid injection hole 27 to replenish the aerosol matrix into the liquid storage chamber 13 through the liquid injection hole 27.

[0064] like Figures 4 to 8 As shown, the upper air guide groove 24 of the first sealing member 2 is also provided with multiple liquid suction columns 242. The liquid suction columns 242 are hollow structures and extend along the height direction into the lower air guide groove 125 of the housing base 12. A through first opening 2421 is opened on the bottom surface of the liquid suction column 242, and a second opening 2422 is opened on the side wall of the liquid suction column 242 near the bottom. The second opening 2422 extends along the height direction to the bottom surface of the liquid suction column 242 and communicates with the first opening 2421. The first opening 2421 and the second opening 2422 of the liquid suction column 242 can generate capillary adsorption of the condensate in the lower air guide groove 125, so that the adsorbed condensate is contained inside the liquid suction column 242. The liquid suction column 242 is a cylindrical structure with an outer diameter of 1.2 mm and an inner diameter of 0.8 mm, which is the diameter of the first opening 2421. Figure 6 , Figure 7 and Figure 8 In the example, a portion of the liquid suction column 242 extends from the bottom to the top of the conductive mounting boss 122 to absorb the condensate on the conductive mounting boss 122, while another portion of the liquid suction column 242 extends directly to a position close to the bottom wall of the lower air guide groove 125 to absorb the condensate on the bottom wall of the lower air guide groove 125.

[0065] In the horizontal direction perpendicular to the height direction, multiple liquid suction columns 242 are arranged at intervals. The gap between some adjacent liquid suction columns 242 is in the size range of 0.6mm to 1.2mm, so that the gap space between adjacent liquid suction columns 242 forms a capillary gap. The capillary gap can adsorb and store condensate through capillary action, achieving an adsorption function similar to that of the liquid suction column 242.

[0066] like Figures 4 to 8 In the example shown, a baffle structure 22 is provided in the upper air guide groove 24 of the first seal 2 near the edge of the air guide hole 21. The air guide hole 21 and the air intake passage 121 are separated on both sides of the baffle structure 22, and the baffle structure 22 laterally blocks the top of the air intake passage 121. The baffle structure 22 can prevent the condensate from directly contacting the top of the air intake passage 121, and at the same time, it can guide the condensate, causing the condensate to flow downward, thereby preventing the condensate flowing out of the air guide hole 21 from directly entering the air intake passage 121 and causing leakage.

[0067] Specifically, such as Figures 4 to 10 In the example shown, the air guide hole 21 is located in the middle of the first sealing member 2, and the air guide hole 21 adopts an elliptical through-hole structure. There are two conductive mounting bosses 122, conductive members 123, liquid injection plugs 124, liquid injection holes 27, air inlets 121, and baffle structures 22, respectively, symmetrically arranged on both sides of the air guide hole 21. The two air inlets 121 are located on both sides of the air guide hole 21, and both are cylindrical air inlet structures; correspondingly, the two baffle structures 22 are both arc-shaped plates, and are centrally symmetrically arranged with respect to the air guide hole 21, so as to separate the two air inlets 121 from the air guide hole on both sides of the corresponding baffle structure 22. For example, Figure 4 In the example, each baffle structure 22 extends along the height direction to the top surface of the corresponding air intake duct 121 to completely block the top surface of the air intake duct 121 laterally.

[0068] The aerosol generating device 500 in this embodiment can not only form a sealing fit with the upper housing 11 and the housing base 12 simultaneously using a single sealing element, thereby reducing the number of sealing elements, simplifying the complexity of the assembly operation, reducing the assembly difficulty, and improving production efficiency; it can also make full use of the space in the air guide cavity 14 to set up multiple liquid absorption columns 242 to absorb the condensate in the air guide cavity 14, preventing excessive accumulation of condensate in the air guide cavity 14 and causing leakage, and there is no need to set up traditional liquid absorption cotton in the air guide cavity 14, which can further reduce space occupation and improve space utilization.

[0069] Furthermore, the aerosol generating device 500 in this embodiment also has all the beneficial effects of the aerosol generating device 100 in any of the above embodiments, which will not be repeated here.
