Description

Technical Field

[0001] This application belongs to the technical field of aerosol generating devices, and particularly relates to a liquid storage tank structure and an aerosol generating device. Background Technology

[0002] An aerosol generator is a device used to heat an aerosol matrix to atomize it and form an aerosol. An aerosol generator includes a storage chamber. Current technology involves directly mounting a sealing silicone plug on the top surface of the storage chamber for sealing. However, as the capacity of the storage chamber increases, the cross-sectional area of ​​the chamber also increases. The sealing silicone plug is made of a relatively soft material, causing the middle part of the plug to deform downwards, which affects the seal between the outer circumferential surface of the silicone plug and the storage chamber. Utility Model Content

[0003] The purpose of this application is to provide a liquid storage tank structure and an aerosol generating device to solve the technical problem in the prior art where the sealing silicone plug that cooperates with the liquid storage tank has a large cross-sectional area, causing the middle part of the sealing silicone plug to deform downward, thereby affecting the seal between the outer circumferential surface of the sealing silicone plug and the liquid storage tank.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: The first aspect of this application provides a liquid storage tank structure for an aerosol generating device, the liquid storage tank structure comprising:

[0005] The liquid storage tank has an internal cavity for containing the aerosol matrix.

[0006] A sealing element is provided at the open end of the receiving cavity and is sealed to the liquid storage tank;

[0007] A support member is provided inside the liquid storage tank and located at the end of the seal that extends into the receiving cavity. The support member is used to limit the deformation of the seal in the direction of extending into the receiving cavity.

[0008] In some implementations, the support is fixedly connected to the liquid storage tank; or, the support and the liquid storage tank are two independent components, with the support supporting the liquid storage tank.

[0009] In some implementations, the liquid storage tank includes a liquid storage tank body and a support part. The liquid storage tank body has a receiving cavity inside, and the support part is disposed on the cavity wall surface of the receiving cavity. The support part abuts against the side of the support member away from the seal member.

[0010] In some implementations, the bearing portion includes at least two bearing protrusions, which are spaced apart along the circumferential direction of the receiving cavity, and the bearing protrusions support the support member.

[0011] In some implementations, the load-bearing part includes at least a load-bearing plate that supports the support member along its thickness direction.

[0012] In some implementations, the supporting part is integrally formed on the main body of the liquid storage tank.

[0013] In some implementations, the support is connected to the seal; or, the support and the seal are two separate components, with the seal supported on the support.

[0014] In some implementations, the support member is provided with a first clearance hole, and the sealing member is provided with a sealing member mating hole. The first clearance hole and the sealing member mating hole are connected and used to be inserted and mated with one end of the atomizing core assembly of the aerosol generator.

[0015] In some implementations, the diameter of the first clearance hole is greater than the diameter of the end of the atomizing core assembly inserted into the first clearance hole, and the difference between the two diameters is in the range of 0.05~0.2mm; or, the diameter of the first clearance hole is not greater than the diameter of the end of the atomizing core assembly inserted into the first clearance hole.

[0016] In some implementations, the support member is provided with a second clearance hole, and the sealing member is provided with an injection hole, with the second clearance hole connected to the injection hole.

[0017] In some implementations, the support is plate-shaped and covers the end of the seal that extends into the receiving cavity.

[0018] In some implementations, the support component is made of metal.

[0019] The second aspect of this application provides an aerosol generating device, including an atomizing core assembly and a liquid storage tank structure provided by any of the above technical solutions. The atomizing core assembly is disposed within the liquid storage tank structure, with one end of the atomizing core assembly connected to the liquid storage tank of the liquid storage tank structure and the other end inserted into a sealing element and sealingly engaged with the sealing element.

[0020] In some implementations, the aerosol generator also includes a nozzle decoration, which is disposed on the side of the seal opposite to the liquid storage tank. The nozzle decoration has an insertion part that inserts into the liquid injection hole of the seal.

[0021] The beneficial effects of this application are as follows: The liquid storage tank structure provided in this application embodiment, by adding a support member and setting the support member at the end of the seal member that extends into the receiving cavity, the support member will prevent the middle part of the seal member from deforming downward, ensuring the reliable sealing between the seal member and the liquid storage tank, and can also reduce the occurrence of liquid squeezing and leakage.

[0059] Please see Figure 1 This application provides an aerosol generator 100, which can heat an aerosol matrix within it to atomize the aerosol matrix and form an aerosol. See also... Figure 2 The aerosol generator 100 has a cavity 11 for containing the aerosol matrix. The aerosol generator 100 also includes an atomizing core assembly 20. The aerosol matrix in the cavity 11 can penetrate into the atomizing core assembly 20. When the atomizing core assembly 20 is connected to current, it can heat the aerosol matrix.

[0060] See some examples. Figure 2 and Figure 3 The aerosol generator 100 also includes a liquid storage tank 1, a sealing element 2, a suction nozzle 30, and a housing 40. Please refer to [link to relevant documentation]. Figure 2 The liquid storage chamber 1 has an internal cavity 11 for containing the aerosol matrix. A sealing element 2 is located at the open end of the cavity 11 and seals against the liquid storage chamber 1. An atomizing core assembly 20 is disposed within the cavity 11. One end of the atomizing core assembly 20 is connected to the liquid storage chamber 1, and the other end is inserted into and seals against the sealing element 2. (See also...) Figure 3 and Figure 5 This illustrates the sealing hole 211 on the sealing element 2, with one end of the atomizing core assembly 20 inserted into the sealing hole 211. Please refer to... Figure 2 The liquid storage chamber 1 is located inside the outer shell 40, and the nozzle 30 is located at one end of the outer shell 40 and the two are connected. An air outlet channel 301 is formed inside the nozzle 30, and the internal channel of the atomizing core assembly 20 is connected to the air outlet channel 301.

[0061] The seal 2 is disposed at the open end of the receiving cavity 11. In some examples, one end of the seal 2 may be inserted into the receiving cavity 11; or, in other examples, the seal 2 may not be inserted into the receiving cavity 11, and the seal 2 may be pressed against the end face of the liquid storage tank 1. The following description mainly takes the example of one end of the seal 2 being inserted into the receiving cavity 11.

[0062] In some examples, the material of seal 2 can be set to silicone or rubber.

[0063] See some examples. Figure 5 The seal 2 includes a seal body 21 and an edge portion 22, the edge portion 22 being disposed on the circumferential side of the seal body 21. (See [link to documentation]). Figure 2 The edge portion 22 is supported on the end face of the liquid storage tank 1, that is, the edge portion 22 is supported on the end face of the liquid storage tank 1 to limit the depth of the seal 2 inserted into the liquid storage tank 1.

[0064] See some examples. Figure 5 An annular protrusion 213 is provided on the wall of the sealing hole 211. The annular protrusion 213 is sealed and engaged with one end of the atomizing core assembly 20. The number of annular protrusions 213 is at least one. When the number of annular protrusions 213 is two or more, each annular protrusion 213 is arranged sequentially at intervals along the axial direction of the sealing hole 211.

[0065] In some examples, the housing 40 and the nozzle 30 can be detachably connected; for example, the housing 40 and the nozzle 30 can be snap-fit ​​connected.

[0066] See some examples. Figure 2 and Figure 3 The aerosol generator 100 also includes a battery 50, a mainboard bracket 60, a mainboard 70, an electrode 80, electrode silicone 90, a button 110, and a button board 120. Please refer to [link / reference needed]. Figure 3 The battery 50 is disposed on one side of the atomizing core assembly 20 along the width direction of the aerosol generator 100. The main board bracket 60 is disposed below the atomizing core assembly 20 and the battery 50. The main board 70 is supported on the main board bracket 60. The electrode silicone 90 is disposed on the liquid storage chamber 1 and located below the atomizing core assembly 20. Two electrodes 80 are mounted on the electrode silicone 90. The two pins 204 of the atomizing core assembly 20 are respectively connected to the corresponding electrodes 80. A button plate 120 is disposed on the side of the electrode silicone 90 away from the battery 50. A button 110 that cooperates with the button plate 120 is disposed on the outer casing 40. The button plate 120, the battery 50 and the electrodes 80 are all electrically connected to the main board 70.

[0067] In some examples, the motherboard bracket 60 can be detachably connected to the liquid reservoir 1, for example, the motherboard bracket 60 can be snap-fitted to the liquid reservoir 1.

[0068] Please see Figure 2 and Figure 3 In this embodiment, the aerosol generating device 100 also includes a support member 3. Please refer to [link to relevant documentation]. Figure 2 The support member 3 is disposed within the liquid storage tank 1 and located at the end of the sealing member 2 that extends into the receiving cavity 11. It is worth noting that, in this embodiment of the application, the structure including the liquid storage tank 1, the sealing member 2, and the support member 3 can be referred to as the liquid storage tank structure 10.

[0069] It should also be noted that since one end of the atomizer core assembly 20 needs to be inserted into the seal 2, a clearance structure such as an opening needs to be provided on the support 3 to allow the atomizer core assembly 20 to be inserted into the seal 2. For example, in some examples, a first clearance hole 31 is provided on the support 3, which is connected to the seal mating hole 211, allowing one end of the atomizer core assembly 20 to pass through the first clearance hole 31 and be inserted into the seal mating hole 211.

[0070] In some examples, the first clearance hole 31 may be located in the central region of the support member 3, and the sealing member mating hole 211 may be located in the central region of the sealing member 2. The first clearance hole 31 and the sealing member mating hole 211 may be coaxially arranged.

[0071] Please see Figure 4 This illustrates that the aerosol generator 100 does not have a support member 3. Increasing the capacity of the liquid storage tank 1 will increase the cross-sectional area of ​​the receiving cavity 11 (cross-section refers to the area of ​​the liquid storage tank 1 parallel to the...). Figure 1 The cross-section of the medium YOZ is also getting larger. Because seal 2 is made of elastic material, and the material of seal 2 is relatively soft, the middle part of seal 2 will... Figure 4 As shown by the dotted line, the downward deformation of the middle part of the seal 2 affects the seal between the outer circumferential surface of the seal 2 and the liquid storage chamber 1. In addition, when the middle part of the seal 2 deforms downward, it may squeeze the aerosol matrix in the receiving cavity 11 into the atomizing core assembly 20. The aerosol matrix squeezed into the atomizing core assembly 20 will flow out of the liquid storage chamber 1 through the atomizing core assembly 20, causing leakage.

[0072] In this embodiment, by adding a support member 3 and placing the support member 3 at one end of the seal member 2 that extends into the receiving cavity 11, the support member 3 will prevent the middle part of the seal member 2 from deforming downwards, ensuring the reliable sealing between the seal member 2 and the liquid storage tank 1, and also reducing the occurrence of liquid squeezing and leakage.

[0073] Please see Figure 5The above embodiment describes the seal 2 as including a seal body 21 and an edge portion 22. It is worth noting that in other embodiments, the seal 2 may also be configured to include only the seal body 21 and not the edge portion 22, and the depth of the seal body 21 inserted into the liquid storage tank 1 may be limited by the seal body 21 contacting the support member 3.

[0074] In some embodiments, see Figure 2 and Figure 3 The aerosol generator 100 also includes a nozzle decoration 130, please refer to [link / reference]. Figure 2 The nozzle decoration 130 is installed between the nozzle 30 and the housing 40.

[0075] In some examples, a nozzle trim 130 may be provided that is pressed between the nozzle 30 and the housing 40.

[0076] In this embodiment of the application, the aerosol generator 100 is further provided with a nozzle decoration 130 for better sealing of the aerosol generator 100.

[0077] In some embodiments, see Figure 2 and Figure 3 The aerosol generator 100 also includes absorbent cotton 140, which is disposed between the nozzle decoration 130 and the sealing element 2. It should be noted that openings need to be provided on the absorbent cotton 140 and the nozzle decoration 130 so that the interior of the atomizing core assembly 20 is connected to the air outlet channel 301 of the nozzle 30.

[0078] In some examples, the seal 2 has a clearance groove on the side facing the nozzle decoration 130, and the absorbent cotton 140 is disposed in the clearance groove.

[0079] In this embodiment, by providing absorbent cotton 140 between the nozzle decoration 130 and the seal 2, the aerosol matrix leaking from one end of the atomizing core assembly 20 can be absorbed, preventing the aerosol matrix from leaking out of the aerosol generator 100 through the nozzle 30.

[0080] In some embodiments, see Figure 3 The support member 3 is provided with a second clearance hole 32, please refer to Figure 3 and Figure 5 The sealing element 2 is provided with an injection hole 212, and the second clearance hole 32 is connected to the injection hole 212.

[0081] In some examples, the second clearance hole 32 is coaxially arranged with the injection hole 212.

[0082] In some examples, at least one injection hole 212 is provided on the seal 2, and the number of injection holes 212 is consistent with the number of second clearance holes 32. When there are two or more injection holes 212, the injection holes 212 are respectively connected to the corresponding second clearance holes 32.

[0083] See some examples. Figure 5 Two injection holes 212 are provided on the sealing element 2, and the two injection holes 212 are symmetrically arranged on both sides of the sealing element mating hole 211.

[0084] In this embodiment of the application, by providing an injection hole 212 on the sealing member 2, the aerosol matrix can be replenished into the receiving cavity 11 through the injection hole 212 after the suction nozzle 30 and the suction nozzle decoration 130 are removed.

[0085] In some embodiments, see Figure 2 and Figure 3 The nozzle decoration 130 has an insertion part 1301 on the side facing the seal 2, and the insertion part 1301 is inserted into the seal 2 and the two are sealed together.

[0086] In some examples, there are two or more injection holes 212, and the number of insertion parts 1301 is consistent with the number of injection holes 212. The insertion parts 1301 are inserted into the corresponding injection holes 212 respectively.

[0087] In some examples, the length of the insertion part 1301 can be set to be able to be inserted only into the injection hole 212; or, in other examples, the insertion part 1301 can be inserted not only into the injection hole 212, but also into the second clearance hole 32.

[0088] In this embodiment, an insertion portion 1301 is formed on the side of the suction nozzle decoration 130 facing the seal 2 to facilitate better sealing of the injection hole 212.

[0089] It should be noted that, please refer to Figure 4 When the insertion part 1301 of the nozzle decoration 130 is inserted downward into the injection hole 212, it will squeeze the seal 2 downward. Especially when the cross-sectional area of ​​the seal 2 is relatively large, it will cause the seal 2 to deform downward, squeezing the aerosol matrix in the receiving cavity 11 into the atomizing core assembly 20. The aerosol matrix squeezed into the atomizing core assembly 20 will flow out of the liquid storage tank 1 through the atomizing core assembly 20, causing leakage. In this embodiment, by adding a support 3 and placing the support 3 at the end of the seal 2 that extends into the receiving cavity 11, the support 3 will prevent the seal 2 from deforming to one side of the receiving cavity 11 and squeezing the aerosol matrix in the receiving cavity 11, thereby reducing the occurrence of squeezing and leakage.

[0090] In some embodiments, the diameter of the first clearance hole 31 is greater than the diameter of the end into which the atomizing core assembly 20 is inserted, and the difference in diameter between the two is in the range of 0.05~0.2mm.

[0091] In some examples, the difference between the diameter of the first clearance hole 31 and the diameter of the end into which the atomizing core assembly 20 is inserted is 0.05~0.1mm, 0.1~0.15mm, or 0.15~0.2mm, etc.

[0092] See some examples. Figure 2 The atomizing core assembly 20 includes an atomizing core cover 201, a cotton layer 202, and a heating element 203. The heating element 203 has a cylindrical structure. The heating element 203, the cotton layer 202, and the atomizing core cover 201 are sequentially arranged from the inside to the outside. The atomizing core cover 201 is provided with a liquid inlet hole. The aerosol matrix in the receiving cavity 11 can penetrate into the cotton layer 202 through the liquid inlet hole. The heating element 203 is provided with two pins 204, which are respectively connected to two electrodes 80. One end of the atomizing core cover 201 is connected to the liquid storage chamber 1, and the other end passes through the first clearance hole 31 and is inserted into the sealing fitting hole 211.

[0093] See some examples. Figure 3 The atomizing core outer cover 201 includes a first section 2011, a second section 2012, and a third section 2013, which are connected in sequence. The cotton layer 202 and the heating element 203 are disposed inside the first section 2011. The diameter of the third section 2013 is smaller than that of the first section 2011. The third section 2013 is inserted through the first clearance hole 31 and into the sealing element mating hole 211. The diameter of the first clearance hole 31 is larger than that of the third section 2013.

[0094] In some examples, the end of the atomizing core assembly 20 away from the support 3 (i.e., the lower end of the atomizing core assembly 20) is riveted to the liquid storage tank 1.

[0095] In this embodiment, when assembling the aerosol generator 100, the bottom of the atomizing core assembly 20 is first installed on the liquid storage tank 1, and then the support member 3 is installed. During the installation of the support member 3, the top of the atomizing core assembly 20 passes through the support member 3. It is worth noting that if the aerosol generator 100 does not include the support member 3, when the lower end of the atomizing core assembly 20 is assembled on the liquid storage tank 1, the atomizing core assembly 20 may tilt, affecting the seal between the end of the atomizing core assembly 20 inserted into the seal member 2 and the seal member 2, potentially leading to oil leakage. In this embodiment, since the aerosol generator 100 includes the support member 3, and by defining the diameter of the first clearance hole 31 and the end of the atomizing core assembly 20 inserted into the first clearance hole 31, the verticality of the atomizing core assembly 20 can be corrected by inserting one end of the atomizing core assembly 20 into the first clearance hole 31 on the support member 3, ensuring the reliability of the sealing fit between the end of the atomizing core assembly 20 and the seal member 2.

[0096] The above embodiment describes that the diameter of the first clearance hole 31 is larger than the diameter of the end of the atomizing core assembly 20 inserted into the first clearance hole 31. In other embodiments, the diameter of the first clearance hole 31 can also be set to be no larger than the diameter of the end of the atomizing core assembly 20 inserted into the first clearance hole 31. Although this is not conducive to the assembly of the support member 3 and the atomizing core assembly 20, the verticality of the atomizing core assembly 20 can still be corrected by inserting one end of the atomizing core assembly 20 into the first clearance hole 31 on the support member 3.

[0097] Please see Figures 6-7 , Figure 6 This is a schematic diagram of the structure of the support member 3 provided in some embodiments of this application. Figure 7 This is a cross-sectional schematic diagram of the support member 3 and the seal member 2 provided in some embodiments of this application.

[0098] In some embodiments, see Figure 6 The support member 3 is plate-shaped and covers one end of the seal member 2 that extends into the receiving cavity 11. For example, please refer to... Figure 6 The support plate 152 is provided with only the first clearance hole 31 and the second clearance hole 32, which not only avoid the sealing hole 211 and the injection hole 212 on the sealing member 2, but also allow the support member 3 to cover the end of the sealing member 2 that extends into the receiving cavity 11.

[0099] The diameter of the first clearance hole 31 is larger than the diameter of the annular protrusion 213, so that one end of the atomizing core assembly 20 can pass through the first clearance hole 31 and be inserted into the sealing fitting hole 211 to seal against the annular protrusion 213. Please refer to Figure 7 The diagram shows that the diameter of the first clearance hole 31 is d, and the diameter of the annular protrusion 213 is D, where d is greater than D.

[0100] See some examples. Figure 7 The first mating hole 211 includes a sealing hole section 2111, and an annular protrusion 213 is provided on the sealing hole section 2111. Please refer to [link to relevant documentation]. Figure 7 The diameter of the sealing hole section 2111 is D′. The diameter of the first clearance hole 31 can be set to be equal to the diameter of the sealing hole section 2111; or, the diameter of the first clearance hole 31 can be set to be slightly larger than the diameter of the sealing hole section 2111.

[0101] See some examples. Figure 7 A chamfer 2112 is provided at one end of the sealing hole section 2111 near the support member 3.

[0102] Regarding the dimensional relationship between the second clearance hole 32 and the injection hole 212, please refer to [link / reference]. Figure 7 The diameter of the injection hole 212 near the support 3 is B, and the diameter of the second clearance hole 32 is b. B can be set to be greater than b, or B can be set to be equal to b, or B can be set to be less than b.

[0103] In some examples, the diameter of the second clearance hole 32 is larger than the diameter of the injection hole 212 at the end near the support member 3. The difference between the diameter of the second clearance hole 32 and the diameter of the injection hole 212 at the end near the support member 3 is no more than 5mm. For example, the difference between the two can be set to 0~1mm, 1~2mm, 2~3mm, 3~4mm, or 4~5mm, etc.

[0104] See some examples. Figure 7 The injection hole 212 includes a first hole segment 2121 and a second hole segment 2122. The first hole segment 2121 is connected to the second hole segment 2122. The first hole segment 2121 is close to the support member 3. The diameter of the first hole segment 2121 is not greater than the diameter of the second hole segment 2122. The diameter of the second hole segment 2122 gradually increases along the direction from close to the first hole segment 2121 to away from the second hole segment 2122.

[0105] In this embodiment, by providing a support member 3 to cover one end of the seal member 2 that extends into the receiving cavity 11, it is possible to avoid the seal member 2 coming into contact with the aerosol matrix in the liquid storage tank 1 over a large area. This is because prolonged contact between the seal member 2 and the aerosol matrix will cause the seal member 2 to change color, and unstable molecules in the seal member 2 will be released into the aerosol matrix, causing odors and other phenomena.

[0106] It is worth noting that the above embodiment describes the support member 3 covering one end of the seal member 2 that extends into the receiving cavity 11. In other embodiments, the support member 3 may not cover the seal member 2 that extends into the receiving cavity 11. For example, in addition to the first clearance hole 31 and the second clearance hole 32, other holes may be provided on the support member 3; or, the support member 3 may be configured as a grid, with grid holes to avoid one end of the atomizing core assembly 20 and the liquid injection hole 212 on the seal member 2.

[0107] In some embodiments, the outer contour shape of the support member 3 matches the shape of the cross-section of the receiving cavity 11. That is, it can be understood that the outer contour shape of the support member 3 is the same as the shape of the corresponding cross-section of the receiving cavity 11.

[0108] See some examples. Figure 7 The four corners of the support member 3 are rounded and chamfered.

[0109] In some embodiments, the support member 3 is a metal plate, that is, the material of the support member 3 is metal.

[0110] In some examples, the material of the support component 3 can be set to corrosion-resistant stainless steel, for example, the material of the support component 3 can be set to SUS316 stainless steel; or, the material of the support component 3 can be set to iron, aluminum, etc. In this case, a protective layer needs to be set on the outer surface of the support component 3 to prevent the support component 3 from reacting with the aerosol matrix.

[0111] In some examples, a dense oxide film is formed on the surface of the support 3.

[0112] In this embodiment, by setting the support member 3 to be a metal plate, the thickness of the support member 3 can be minimized while preventing the seal member 2 from deforming downwards.

[0113] It should be noted that the above embodiment describes the support member 3 as being made of metal. In other embodiments, the support member 3 may also be made of non-metallic material. In this case, it may be necessary to increase the thickness of the support member 3 so that the support member 3 has sufficient strength to prevent the seal member 2 from deforming downward.

[0114] In some embodiments, the support member 3 is a metal plate, and the thickness of the support member 3 ranges from 0.5mm to 1mm. That is, the thickness of the support member 3 should not be too small, so as to prevent the support member 3 from being unable to effectively prevent the seal member 2 from deforming downward. Of course, the thickness of the support member 3 should not be too large either, so as to avoid occupying too much space and increasing the volume of the aerosol generating device 100. Therefore, in the embodiments of this application, the thickness range of the support member 3 is limited to 0.5mm to 1mm.

[0115] In some examples, the thickness of the support member 3 can be set to a range of 0.5mm~0.6mm, 0.6mm~0.7mm, 0.7mm~0.8mm, 0.8mm~0.9mm, or 0.9mm~1.0mm, etc.

[0116] Please see Figures 8-11 , Figure 8 This is a schematic diagram of the structure of the liquid storage tank 1 provided in some embodiments of this application. Figure 9 This is a schematic diagram of the liquid storage tank 1 from another angle, provided in some embodiments of this application. Figure 10 A top view of the liquid storage tank 1 provided in some embodiments of this application. Figure 1 , Figure 11 A top view of the liquid storage tank 1 provided in some embodiments of this application. Figure 2 .

[0117] In some embodiments, the support member 3 is fixedly connected to the liquid storage tank 1; or, the support member 3 and the liquid storage tank 1 are two independent components, that is, the support member 3 and the liquid storage tank 1 are not connected to each other, and the support member 3 is supported on the liquid storage tank 1.

[0118] When the support member 3 is fixedly connected to the liquid storage tank 1, in some examples, the support member 3 can be set to be pasted to the liquid storage tank 1 or snapped onto the liquid storage tank 1.

[0119] In this embodiment of the application, by setting the support member 3 to be fixedly connected to the liquid storage tank 1, the support member 3 can be stably connected; setting the support member 3 and the liquid storage tank 1 as two independent components and the support member 3 supporting the liquid storage tank 1 can simplify the structure and facilitate the assembly of the support member 3 onto the liquid storage tank 1.

[0120] In some embodiments, see Figure 8 The liquid storage tank 1 includes a liquid storage tank body 14 and a support part 15. The liquid storage tank body 14 has a receiving cavity 11 inside. The support part 15 is disposed on the cavity wall of the receiving cavity 11, and the support member 3 is supported on the support part 15.

[0121] In some examples, the support portion 15 is integrally formed on the liquid storage tank body 14 to reduce the number of parts; or, in other examples, the support portion 15 may be attached or snapped onto the liquid storage tank body 14.

[0122] See some examples. Figure 8 and Figure 9 A battery placement cavity 12 is provided on the main body 14 of the liquid storage tank. The battery placement cavity 12 is located along the width direction of the receiving cavity 11 in the liquid storage tank main body 14 (i.e., Figure 8 On one side (in the Y-axis direction), the battery placement cavity 12 opens to the liquid storage tank body 14 along the thickness direction (i.e., Figure 8On one side (in the Z-axis direction), the battery 50 can be placed inside the battery placement cavity 12.

[0123] See some examples. Figure 9 A silicone placement cavity 13 is provided on the main body 14 of the liquid storage chamber. The silicone placement cavity 13 is located below the receiving cavity 11 and the two are connected. The electrode silicone 90 is installed in the silicone placement cavity 13. The pin 204 of the atomizing core assembly 20 can be inserted into the electrode silicone 90 and connected to the electrode 80.

[0124] In some examples, the cavity wall of the receiving cavity 11 includes a first cavity wall surface 111 and a second cavity wall surface 112 disposed opposite to each other, the first cavity wall surface 111 and the second cavity wall surface 112 being along the thickness direction of the aerosol generating device 100. Figure 8 For relative settings in the Z-axis direction, please refer to [link / reference]. Figure 8 A portion of the first cavity wall 111 protrudes toward the second cavity wall 112 to form a protruding region 1111.

[0125] In some embodiments, see Figure 10 The support portion 15 includes at least two support protrusions 151, which are spaced apart along the circumferential direction of the receiving cavity 11.

[0126] The support portion 15 includes at least two support protrusions 151, that is, the support portion 15 may include two, three, four or five support protrusions 151.

[0127] See some examples. Figure 10 There are four bearing protrusions 151, and two bearing protrusions 151 are respectively provided on the two opposite cavity walls of the receiving cavity 11.

[0128] See some examples. Figure 8 The supporting protrusion 151 can be set in a long strip shape, and along the length direction of the liquid storage tank body 14. Figure 8 Extending along the X-axis; or, in other examples, the bearing protrusion 151 can be set to be non-strip-shaped, for example, the bearing protrusion 151 can be set to be block-shaped or hemispherical, etc.

[0129] See some examples. Figure 8 Two or more bearing protrusions 151 are provided on the first cavity wall 111, and the two bearing protrusions 151 on the first cavity wall 111 are located above the protrusion area 1111. The bearing protrusions 151 on the first cavity wall 111 extend along the length direction of the liquid storage tank body 14. Two or more bearing protrusions 151 are provided on the second cavity wall 112, and the bearing protrusions 151 on the second cavity wall 112 extend along the length direction of the liquid storage tank body 14 and extend to the bottom surface near the receiving cavity 11.

[0130] In some examples, the cross-sectional area of ​​the supporting protrusion 151 is 2 mm. 2 ~10mm 2 For example, the cross-sectional area of ​​the supporting protrusion 151 can be set to 2mm. 2 ~4mm 2 Or 4mm 2 ~6mm 2 Or 6mm 2 ~8mm 2 Or 8mm 2 ~10mm 2 etc., where the cross-sectional area of ​​the supporting protrusion 151 is equal to... Figure 8 The planes in the middle YOZ are parallel.

[0131] In some embodiments, see Figure 11 The supporting part 15 includes at least a supporting plate 152.

[0132] In some examples, the support portion 15 may consist only of a support plate 152, and the support portion 15 may include one support plate 152 in an annular shape. Alternatively, the support portion 15 may include two or more support plates 152, spaced apart along the circumferential direction of the receiving cavity 11. In other examples, the support portion 15 may include not only the support plate 152, but may also include a support protrusion 151. Please refer to [link to relevant documentation]. Figure 11 The diagram illustrates that the support portion 15 includes both a support plate 152 and a support protrusion 151.

[0133] It is worth noting that the bearing plate 152 is a plate. The length of the bearing plate 152 along the radial direction of the receiving cavity 11 is greater than the length of the bearing protrusion 151 along the radial direction of the receiving cavity 11. The length of the bearing plate 152 along the circumferential direction of the receiving cavity 11 is greater than the length of the bearing protrusion 151 along the circumferential direction of the receiving cavity 11.

[0134] See some examples. Figure 11 The supporting part 15 includes a supporting plate 152 and a supporting protrusion 151. Please refer to [link / reference]. Figure 11 The diagram illustrates the first cavity wall 111, the second cavity wall 112, and the third cavity wall 113 of the receiving cavity 11. The bearing plate 152 is L-shaped and connects the first cavity wall 111 and the third cavity wall 113. One or more bearing protrusions 151 are provided on the second cavity wall 112.

[0135] It is worth noting that since the area of ​​the bearing plate 152 is larger than the cross-sectional area of ​​the bearing protrusion 151, the bearing plate 152 provides better support for the support member 3 compared to the bearing protrusion 151. In some scenarios, when the area of ​​the support member 3 is relatively small, the bearing portion 15 can be configured to include at least two bearing protrusions 151, that is, the support member 3 is supported by the bearing protrusions 151, which can reduce the material used in the bearing portion 15 while still providing support for the support member 3; when the area of ​​the support member 3 is relatively large, the bearing portion 15 can be configured to include at least the bearing plate 152, which can improve the strength of the support and provide more stable support for the support member 3.

[0136] In some scenarios, when the receiving cavity 11 has a small capacity, such as 0.5-3ML, the supporting part 15 can be provided to include at least two supporting protrusions 151; when the receiving cavity 11 has a large capacity, such as 3ML or more, the supporting part 15 can be provided to include at least a supporting plate 152.

[0137] In some embodiments, the support member 3 is connected to the seal member 2; or, the support member 3 and the seal member 2 are two independent components, that is, the support member 3 and the seal member 2 are not connected to each other, and the seal member 2 is supported on the support member 3.

[0138] When the support 3 is connected to the seal 2, in some examples, the support 3 and the seal 2 can be bonded together.

[0139] In some examples, the support 3 and the liquid storage tank 1 are two separate components, with the support 3 supported on the liquid storage tank 1; the support 3 and the seal 2 are two separate components, with the seal 2 supported on the support 3.

[0140] In this embodiment, by setting the support member 3 to be connected to the seal member 2, a stable connection of the support member 3 can be achieved; setting the support member 3 and the seal member 2 as two independent components and the seal member 2 supported on the support member 3 can simplify the structure and facilitate the assembly of the support member 3 on the liquid storage tank 1.

[0141] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
