[0002] An atomizing device is a device used to heat an aerosol matrix to form an aerosol. The reservoir of an atomizing device is usually pre-filled with the aerosol matrix. To prevent leakage of the aerosol matrix from the atomizing core during transportation, many existing technologies employ complex structures to separate the aerosol matrix from the atomizing core. This not only increases costs but also requires the user to operate the atomizing device upon first use to connect the aerosol matrix and the atomizing core. Utility Model Content

[0026] Please see Figures 1-2 , Figure 1 This is a schematic diagram of the structure of the atomizing device 100 provided in some embodiments of this application. Figure 2 This is a cross-sectional schematic diagram of an atomizing device 100 provided in some embodiments of this application.

[0027] Please see Figure 2 The atomizing device 100 provided in this application embodiment includes a battery assembly 20 and an atomizer 10, with the atomizer 10 connected to the battery assembly 20.

[0028] See some examples. Figure 2 The atomizer 10 includes an atomizing core assembly 11, a liquid storage chamber 12, an atomizing support 13, and a mouthpiece 14. The mouthpiece 14 is located at one end of the liquid storage chamber 12. The atomizing support 13 is inserted into the liquid storage chamber 12 from the side of the liquid storage chamber away from the mouthpiece 14. The atomizing core assembly 11 is located inside the liquid storage chamber 12. Both ends of the atomizing core assembly 11 are supported on the atomizing support 13 and the liquid storage chamber 12, respectively, and both ends of the atomizing core assembly 11 are sealed to the atomizing support 13 and the liquid storage chamber 12. Please refer to [link to relevant documentation]. Figure 2 The liquid storage chamber 12, the atomizing support 13 and the atomizing core assembly 11 form a liquid storage cavity 15, which is used to contain the aerosol matrix.

[0029] See some examples. Figure 2 The battery assembly 20 includes a battery 21, a circuit board 22, and an internal support 23. The battery 21 and the circuit board 22 are supported on the internal support 23. The battery 21 is electrically connected to the circuit board 22. The atomizing core assembly 11 is electrically connected to the circuit board 22. The battery 21 is used to supply power to the atomizing core assembly 11. When the atomizing core assembly 11 is working, it can heat the aerosol matrix that has penetrated into the atomizing core assembly 11.

[0030] Regarding the connection method between the battery assembly 20 and the atomizer 10, the battery assembly 20 and the atomizer 10 can be set to be detachable, or the battery assembly 20 and the atomizer 10 can be set to be non-detachable.

[0031] See some examples. Figure 1 and Figure 2The atomizing device 100 also includes a housing 30, which is fitted over the atomizer 10 and the battery assembly 20.

[0032] Please see Figures 3-6 , Figure 3 This is a front view schematic diagram of an atomizing core assembly 11 provided in one embodiment of this application. Figure 4 This is a schematic diagram of the structure of the atomizing core assembly 11 provided in the embodiments of this application (the heat-melting part 111 is not shown). Figure 5 for Figure 2 A magnified view of a portion of point A in the middle. Figure 6 This is a partial cross-sectional view of the liquid inlet 1121 provided in some embodiments of this application, where the heat-fusion part 111 is not provided.

[0033] Please see Figure 3 The atomizing core assembly 11 provided in this application embodiment includes an atomizing core body 16 and a heat-fused part 111, the heat-fused part 111 being disposed on the atomizing core body 16; please refer to Figure 4 A liquid inlet hole 1121 is provided on the outer peripheral side of the atomizing core body 16. A heat-melting part 111 is provided on the atomizing core body 16 and is used to block the liquid inlet hole 1121. The heat-melting part 111 is configured to melt under the heating action of the atomizing core body 16.

[0034] The heat-melting part 111 provided in this embodiment is a heat-melting material, which is a type of material that is solid at room temperature but rapidly melts into a liquid state when heated (reaching a specific melting temperature). Before using the atomizing device 100, the heat-melting part 111 blocks the liquid inlet hole 1121. Please refer to [link to relevant documentation]. Figure 5 Due to the obstruction of the heat-fused section 111, the aerosol matrix in the storage chamber 15 cannot flow towards the inlet hole 1121 along the arrow, thus preventing leakage of the aerosol matrix from the atomizing core 17 of the atomizing device 100 during transportation. When the atomizing device 100 is used for the first time, starting the atomizing device 100 can heat the atomizing core body 16 to melt the heat-fused section 111, preventing the heat-fused section 111 from blocking the inlet hole 1121. At this time, please refer to... Figure 6 The aerosol matrix in the liquid storage chamber 15 can flow into the atomizing core body 16 through the liquid inlet hole 1121, so that the atomizing core body 16 can heat the aerosol matrix that has penetrated into it.

[0035] In summary, in this embodiment of the application, by providing a heat-fused part 111 to seal the liquid inlet hole 1121, the leakage of the aerosol matrix from the atomizing core 17 of the atomizing device 100 during transportation can be effectively prevented; by providing a heat-fused part 111 as a heat-fused material, the atomizing core body 16 can melt the heat-fused part 111 during operation when the atomizing device 100 is used normally for the first time, so that the atomizing device 100 can be used normally; in this embodiment of the application, the use of a heat-fused part 111 made of heat-fused material to seal the liquid inlet hole 1121 can avoid the technical problems of complex structure and high cost in the prior art of using mechanical structure to separate the aerosol matrix from the atomizing core.

[0036] In some embodiments, the material of the hot melt part 111 is one of paraffin wax, hot melt adhesive or rosin, that is, the hot melt part 111 is one of paraffin wax structural part, hot melt adhesive structural part or rosin structural part.

[0037] Paraffin wax is a solid hydrocarbon mixture obtained from petroleum fractionation. It is a white or pale yellow translucent solid at room temperature, with a melting point range of 40℃-85℃. The density of paraffin wax in its solid state at room temperature is 0.89. -0.93 .

[0038] It should be noted that, considering the safety of using the atomizing device 100 provided in this application, when the material of the hot-melt part 111 is paraffin wax, food-grade paraffin wax is preferred. Food-grade paraffin wax is high-purity paraffin wax that meets national food safety standards, can come into direct or indirect contact with food, and will not cause harm to human health under specified use conditions.

[0039] Hot melt adhesives are a type of thermoplastic adhesive that is solid at room temperature, melts upon heating, rapidly transforms into a flowing liquid, and solidifies quickly upon cooling to achieve bonding. The melting point range of hot melt adhesives is 70℃-200℃, and their sealing range is 0.90. -1.30 .

[0040] Rosin is a natural resin extracted from coniferous trees such as pine. Its main component is resin acid. At room temperature, it is a transparent or translucent brittle solid, ranging in color from light yellow to dark brown. It has a distinctive rosin odor and softens and melts easily upon heating. The melting point of rosin ranges from 70℃ to 160℃. The sealing temperature of rosin is 1.04... -1.10 .

[0041] It should be noted that, considering that the high melting point temperature of the hot melt part 111 is not conducive to the hot melt part 111 being melted when the atomizing core body 16 is working, in some examples, the melting point temperature of the hot melt part 111 can be set to be no greater than 90°C.

[0042] It should be noted that, considering that a low melting point temperature of the heat-melting part 111 is not conducive to the stable sealing of the liquid inlet hole 1121 by the heat-melting part 111, in some examples, the melting point temperature of the heat-melting part 111 can be set to be not less than 60°C.

[0043] It should be noted that after the hot melt part 111 melts and releases the blockage of the liquid inlet 1121, the hot melt part 111 can preferably float on the aerosol matrix in the liquid storage chamber 15. Therefore, the sealing of the hot melt part 111 can be set to be less than the density of the aerosol matrix.

[0044] In some examples, the density range of the aerosol matrix can be set to 1.0. -1.2 .

[0045] In this embodiment, the material of the hot melt part 111 is limited to one of paraffin wax, hot melt adhesive or rosin, so that the hot melt part 111 can be melted to release the blockage of the liquid inlet hole 1121 when the atomizing core body 16 is working for the first time.

[0046] In some embodiments, see Figure 4 An annular groove 1122 is provided on the outer side of the atomizing cover 112, and a liquid inlet 1121 is provided on the bottom surface of the annular groove 1122. At least a heat-melting part 111 is provided in the annular groove 1122 to seal each liquid inlet 1121.

[0047] Please see Figure 5 The annular groove 1122 includes a groove side surface 11221 and a groove bottom surface 11222. The two groove side surfaces 11221 are arranged opposite each other along the axial direction of the atomizing cover 112. The groove bottom surface 11222 connects the two groove side surfaces 11221. The liquid inlet hole 1121 is provided on the groove bottom surface 11222.

[0048] See some examples. Figure 5 Along the direction from near the bottom surface 11222 of the groove to away from the bottom surface 11222 of the groove, the side surface 11221 of the groove is inclined in the direction away from the other side surface 11221 of the groove, so as to facilitate the processing of the annular groove 1122.

[0049] In some examples, a ring of liquid inlet holes 1121 is provided on the atomizing cover 112 at intervals along the circumferential direction, and the ring of liquid inlet holes 1121 is provided on the bottom surface of the same annular groove 1122; or, in other examples, two or more rings of liquid inlet holes 1121 are provided on the atomizing cover 112, and each ring of liquid inlet holes 1121 is provided at intervals along the axial direction of the atomizing cover 112. In this case, one annular groove 1122 can be provided on the atomizing cover 112, and each liquid inlet hole 1121 is provided on the bottom surface of the same annular groove 1122. Alternatively, two or more annular grooves 1122 can be provided on the atomizing cover 112, and the liquid inlet holes 1121 in each ring are respectively provided on the bottom surface of the corresponding annular groove 1122.

[0050] In this embodiment of the application, by defining at least an annular groove 1122 with a heat-melting part 111, it is convenient to quickly seal the liquid inlet holes 1121 of the same ring.

[0051] In some embodiments, the groove wall surface of the annular groove 1122 may be set as a rough surface to facilitate the stable placement of the hot-melt part 111 within the annular groove 1122.

[0052] Please see Figures 7-8 , Figure 7 for Figure 3 Schematic diagram of the sectional view along the middle AA direction. Figure 8 Another cross-section of the atomizing device 100 provided in some embodiments of this application Figure 1 .

[0053] Regarding the provision of a heat-fused portion 111 within at least the annular groove 1122 for sealing each liquid inlet hole 1121, it can be understood that in some embodiments, please refer to [the relevant documentation]. Figure 7 The heat-melting part 111 is only provided in the annular groove 1122 and not in each liquid inlet hole 1121; or, in other embodiments, please refer to Figure 8 The hot-melting part 111 is simultaneously provided in the annular groove 1122 and each liquid inlet hole 1121.

[0054] By limiting the hot melt section 111 to be provided only on the annular groove 1122, it is possible to ensure stable sealing of each liquid inlet hole 1121 while minimizing the material used for the hot melt section 111. By limiting the hot melt section 111 to be provided in both the annular groove 1122 and each liquid inlet hole 1121, it is convenient to form the hot melt section 111 on the atomizing core body 16.

[0055] In some embodiments, see Figure 7The hot-melting part 111 includes an annular segment 1111, which is disposed in an annular groove 1122. Along the radial direction of the atomizing core assembly 11, the depth of the annular groove 1122 is not less than the thickness of the annular segment 1111.

[0056] Regarding the requirement that the depth of the annular groove 1122 is not less than the thickness of the annular segment 1111, the depth of the annular groove 1122 can be set to be equal to the thickness of the annular segment 1111, or the depth of the annular groove 1122 can be set to be greater than the thickness of the annular segment 1111.

[0057] In this embodiment, the depth of the annular groove 1122 is not less than the thickness of the annular segment 1111, so as to prevent the annular segment 1111 from protruding from the annular groove 1122, which would easily cause the hot melt part 111 to be damaged during the assembly of the atomizing device 100, thereby affecting the sealing of the liquid inlet hole 1121.

[0058] Regarding the shape of the liquid inlet 1121, in some embodiments, the liquid inlet 1121 can be set as a circular hole; or, in other embodiments, the liquid inlet 1121 can be set as a square hole or an elliptical hole, etc.

[0059] When the liquid inlet hole 1121 is a circular hole, in some examples, the diameter of the liquid inlet hole 1121 can be set to a range of 1mm to 3mm.

[0060] In some embodiments, the width of the annular groove 1122 along the axial direction of the atomizing core assembly 11 is slightly larger than the diameter of the liquid inlet hole 1121.

[0061] In some examples, the difference between the width of the annular groove 1122 along the axial direction of the atomizing core assembly 11 and the diameter of the liquid inlet 1121 is no more than 3 mm.

[0062] In this embodiment, the width of the annular groove 1122 along the axial direction of the atomizing core assembly 11 is slightly larger than the diameter of the liquid inlet hole 1121, so as to minimize the material used in the hot melt section 111.

[0063] Please see Figures 9-10 , Figure 9 Another cross-section of the atomizing device 100 provided in some embodiments of this application Figure 2 , Figure 10 Another cross-section of the atomizing device 100 provided in some embodiments of this application Figure 3 .

[0064] In some embodiments, see Figure 9 and Figure 10 The heat-melting part 111 includes multiple insertion sections 1112, each insertion section 1112 being inserted into a corresponding liquid inlet hole 1121 to achieve the sealing of each liquid inlet hole 1121.

[0065] See some examples. Figure 9 The length of the insertion segment 1112 along the radial direction of the atomizing core assembly 11 is equal to the length of the liquid inlet 1121, and both ends of the insertion segment 1112 are flush with both ends of the liquid inlet 1121; or, in other examples, please refer to Figure 10 The length of the insertion section 1112 along the radial direction of the atomizing core assembly 11 is less than the length of the liquid inlet hole 1121, and the insertion section 1112 is located inside the liquid inlet hole 1121.

[0066] It should also be noted that when the heat-melting part 111 includes multiple insertion segments 1112 and each insertion segment 1112 is inserted into the corresponding liquid inlet hole 1121 to achieve the sealing of each liquid inlet hole 1121, it is not necessary to provide an annular groove 1122 on the outer peripheral surface of the atomizing core body 16.

[0067] In this embodiment of the application, by setting each insertion segment 1112 to be inserted into the corresponding liquid inlet hole 1121, the material used in the hot melt part 111 is reduced.

[0068] Please see Figures 11-12 , Figure 11 This is a top view schematic diagram of the atomizing core assembly 11 provided in some embodiments of this application. Figure 12 for Figure 11 Schematic diagram of the BB-direction section.

[0069] In some embodiments, see Figure 12 The atomizing core body 16 includes an atomizing outer cover 112, a liquid storage component 113 and an atomizing core 17. The atomizing core 17, the liquid storage component 113 and the atomizing outer cover 112 are sequentially arranged from the inside to the outside. The atomizing outer cover 112 is provided with a liquid inlet hole 1121 and the liquid storage component 113 contains an aerosol matrix.

[0070] In some examples, the material of the liquid storage component 113 may be set to organic cotton, ceramic cotton, bamboo fiber cotton, or composite cotton, etc.

[0071] In some examples, the atomizing cover 112 is made of a thermally conductive material with a certain strength. For example, the atomizing cover 112 can be made of metal. In one specific example, the atomizing cover 112 can be made of stainless steel.

[0072] See some examples. Figure 12 The length of the liquid storage component 113 along the axial direction of the atomizing core assembly 11 is less than the length of the atomizing outer cover 112, and the liquid storage component 113 is tightly fitted to the inner side of the atomizing outer cover 112.

[0073] In this embodiment, the atomizing core 17 generates heat when energized, and the heat can be transferred to the atomizing cover 112 through the liquid storage component 113. When the temperature of the atomizing cover 112 rises, the heat-fused part 111 can be melted. In addition, the liquid storage component 113 in this embodiment stores an aerosol matrix. When the atomizing core 17 generates heat when energized, it can heat the aerosol matrix in the liquid storage component 113 to prevent the atomizing core assembly 11 from burning dry.

[0074] It should be noted that the liquid storage component 113 can be configured to store a certain amount of aerosol matrix. When the user uses the atomizing device 100 for the first time, during the process from heating to melting of the hot-melt section 111, the aerosol matrix stored in the liquid storage component 113 can ensure normal use of the atomizing device 100. That is, before the aerosol matrix in the liquid storage chamber 15 has penetrated into the liquid storage component 113 through the liquid inlet 1121, the atomizing core 17 can heat the aerosol matrix stored in the liquid storage component 113 to generate aerosol. In other words, the content of the aerosol matrix stored in the liquid storage component 113 is such that the hot-melt section 111 has been melted before the aerosol matrix stored in the liquid storage component 113 has been fully heated, and after the hot-melt section 111 has been melted, the aerosol matrix in the liquid storage chamber 15 has penetrated into the liquid storage component 113 through the liquid inlet 1121.

[0075] In some of the embodiments mentioned above, an annular groove 1122 is provided on the outer surface of the atomizing core assembly 11. When the atomizing core body 16 includes an atomizing cover 112, a liquid storage component 113 and an atomizing core 17, the annular groove 1122 is provided on the atomizing cover 112. In some embodiments, the depth of the annular groove 1122 along the radial direction of the atomizing core assembly 11 is not greater than half the thickness of the atomizing cover 112, so as not to affect the strength of the atomizing cover 112 at the annular groove 1122.

[0076] In some embodiments, see Figure 12 The atomizing core 17 includes a support 114, a liquid guiding component 115, and a heating element 116. The support 114 is sleeved on the outside of the liquid guiding component 115. The support 114 is tightly fitted with the inner side of the liquid storage component 113. The heating element 116 is disposed on the inner side of the liquid guiding component 115.

[0077] In some examples, the material of the liquid guiding component 115 can be set to organic cotton, ceramic cotton, bamboo fiber cotton, or composite cotton, etc.

[0078] In some examples, the heating element 116 can be configured as a heating wire or a heating mesh. The heating element 116 is electrically connected to the battery assembly 20. When current flows through the heating element 116, it generates heat. The heat can be transferred to the atomizing cover 112 through the liquid guide 115 and the liquid storage 113. Although the liquid guide 115 and the liquid storage 113 have a certain heat insulation effect, when the temperature of the heating element 116 is around 80°C, the temperature of the atomizing cover 112 can be between 45°C and 65°C. Therefore, during the first operation of the atomizing core body 16, the hot melt part 111 with a relatively low melting point can be melted and heated.

[0079] As described in the above embodiments, the liquid storage component 113 stores an aerosol matrix. When the atomizing device 100 provided in this application embodiment is used for the first time, the heating element 116 generates heat after being powered on, which can guide the aerosol matrix in the liquid storage component 113 to permeate through the liquid guide component 115, thereby enabling the heating element 116 to heat the aerosol matrix and prevent the atomizing core assembly 11 from burning dry. During the first operation, the atomizing core body 16 can melt the hot melt part 111, so that the aerosol matrix can flow through the liquid inlet hole 1121 to the liquid storage component 113, and permeate through the opening on the support member 114 to the liquid guide component 115. The heating element 116 heats the aerosol matrix to evaporate into gas. When there is airflow inside the atomizing core assembly 11, the evaporated aerosol matrix is ​​cooled and atomized to form an aerosol.

[0080] In this embodiment, the atomizing core 17 is provided with a support 114, a liquid guiding component 115, and a heating component 116 to ensure the normal operation of the atomizing core assembly 11.

[0081] In some embodiments, see Figure 12 The length of the liquid guiding component 115 is less than the length of the liquid storage component 113. For example, the length of the liquid guiding component 115 can be set to be no more than half the length of the liquid storage component 113.

[0082] It should be noted that the dimensions of the liquid guiding component 115 along the length of the atomizing core assembly 11 are matched with the dimensions of the heating element 116 along the length of the atomizing core assembly 11. Generally, the dimensions of the liquid guiding component 115 along the length of the atomizing core assembly 11 are slightly larger than the dimensions of the heating element 116 along the length of the atomizing core assembly 11.

[0083] In some embodiments, the thickness of the liquid guide 115 is less than the thickness of the liquid reservoir 113 along the radial direction of the atomizing core assembly 11.

[0084] In some embodiments, see Figure 12 Along the radial direction of the atomizing core assembly 11, the hot-melt part 111 faces the liquid guide 115.

[0085] Regarding the liquid inlet 1121 facing the liquid guide 115 in the radial direction of the atomizing core assembly 11, it can be understood that the projection of the hot melt part 111 onto the liquid guide 115 in the radial direction of the atomizing core assembly 11 completely falls onto the liquid guide 115.

[0086] In some examples, the heat-melting section 111 may be positioned directly opposite the central region of the liquid guide 115 along its own axial direction.

[0087] In this embodiment, by setting the heat-melting part 111 in the radial direction of the atomizing core assembly 11 to face the liquid guiding member 115, the heat-melting part 111 is as close as possible to the liquid guiding member 115 and the heating member 116 in the axial direction of the atomizing core assembly 11, so as to facilitate the rapid transfer of heat to the heat-melting part 111, thereby facilitating the rapid fusion of the heat-melting part 111.

[0088] In some embodiments, see Figure 12 The atomizing core assembly 11 includes a first end 18 and a second end 19 along its own axis. The first end 18 is used to cooperate with the atomizing bracket 13, and the second end 19 is used to seal with the liquid storage chamber 12. The atomizing core 17 is closer to the first end 18 than the second end 19.

[0089] In some embodiments, there is at least one heating element 116. When there are two or more heating elements 116, each heating element 116 is arranged sequentially along the axial direction of the atomizing core assembly 11.

[0090] In this embodiment, the number of heating elements 116 can be one, or the number of heating elements 116 can be greater than one. Please refer to [link to relevant documentation]. Figure 12 This illustrates that there are two heating elements 116, arranged sequentially along the axis of the atomizing core assembly 11. Please refer to [link / reference]. Figure 12 The heating element 116 is connected to pin 120, which can be electrically connected to the battery assembly 20.

[0091] Taking two heating elements 116 as an example, for ease of description, the two heating elements 116 are referred to as the first heating element and the second heating element, respectively. When using the atomizing device 100, only the first heating element or the second heating element can be controlled to be in working state, or the first heating element and the second heating element can be controlled to be in working state at the same time, thereby adjusting the working temperature of the atomizing core 17.

[0092] In this embodiment, by setting two or more heating elements 116, the working temperature of the atomizing core 17 can be controlled according to the needs, so as to meet the user's needs for the atomizing device 100.

[0093] In some embodiments, see Figure 12The atomizing core assembly 11 also includes an atomizing base 110. The atomizing base 110 is inserted into the support member 114 from the bottom of the atomizing core assembly 11. A guide groove is provided on the outer periphery of the atomizing base 110. The pin 120 connected to the heating element 116 extends out of the atomizing core assembly 11 through the corresponding guide groove.

[0094] In this embodiment, the atomizing core assembly 11 is further provided with an atomizing base 110 to prevent short circuits from occurring when the pins 120 come into contact.

[0095] In some embodiments, see Figure 12 The atomizing core body 16 also includes a first sealing element 117 and a second sealing element 118. The first sealing element 117 and the second sealing element 118 are disposed at both ends of the liquid storage element 113 along the axial direction of the atomizing core body 16. The first sealing element 117 is closer to the liquid inlet hole 1121 than the second sealing element 118.

[0096] See some examples. Figure 12 A portion of the outer peripheral side of the first seal 117 is exposed outside the atomizing cover 112, and the outer peripheral side of the first seal 117 exposed outside the atomizing cover 112 is used to seal with the atomizing bracket 13.

[0097] In some examples, one end of the first seal 117 inserted into the atomizing cover 112 contacts the liquid reservoir 113.

[0098] See some examples. Figure 12 An annular slot 1181 is provided on the end face of the second sealing member 118 facing the first atomizing cover 112. One end of the atomizing cover 112 is inserted into the annular slot 1181 and the atomizing cover 112 is sealed with the second sealing member 118.

[0099] See some examples. Figure 12 An annular protrusion 1182 is formed on the end face of the second seal 118 facing the atomizing cover 112. The annular protrusion 1182 is inserted into the atomizing cover 112 and contacts one end of the liquid storage component 113.

[0100] In this embodiment, the atomizing core body 16 is further provided with a first sealing element 117 and a second sealing element 118 to achieve a sealed fit between the atomizing core assembly 11, the atomizing bracket 13, and the liquid storage chamber 12.

[0101] In some embodiments, see Figure 12The inner circumferential side of the first seal 117 is sealed to the outer circumferential side of the support 114, and the outer circumferential side of the second seal 118 is sealed to the inner circumferential side of the atomizing cover 112, so as to prevent the aerosol matrix in the liquid storage 113 from leaking downward out of the atomizing core assembly 11.

[0102] In some embodiments, see Figure 12 The first sealing member 117 includes a first hole 1171 and a second hole 1172. The first hole 1171 and the second hole 1172 are arranged sequentially along the axial direction of the first sealing member 117 and are connected to each other. The first hole 1171 and the second hole 1172 are coaxially arranged, and the diameter of the first hole 1171 is larger than the diameter of the second hole 1172. The diameter of the second hole 1172 is smaller than the diameter of the support member 114. The support member 114 can be inserted into the first hole 1171 and supported on the stepped surface between the first hole 1171 and the second hole 1172.

[0103] In some embodiments, see Figure 12 The second sealing member 118 is provided with a first liquid suction member 119 on the side opposite to the liquid storage member 113.

[0104] Please see Figure 2 The liquid storage chamber 12 has a mating hole 121 inside, which is located on the side of the liquid storage chamber 12 away from the atomizing bracket 13. The second sealing member 118 is disposed in the mating hole 121 and is sealed with the mating hole 121. The first liquid suction member 119 is disposed between the second sealing member 118 and the inner side end face of the liquid storage chamber 12. The second sealing member 118 and the first liquid suction member 119 are provided with through holes. The suction nozzle 14 has an airflow channel 141. The openings on the second sealing member 118 and the first liquid suction member 119 are connected to the airflow channel 141.

[0105] See some examples. Figure 12 An installation groove 1183 is provided on the end face of the first sealing member 117 facing away from the liquid storage member 113, and the first liquid suction member 119 is disposed in the installation groove 1183.

[0106] In some examples, the first absorbent element 119 can be configured as absorbent cotton.

[0107] In this embodiment, a first liquid-absorbing element 119 is provided on the side of the second sealing element 118 that is away from the liquid storage element 113, and the first liquid-absorbing element 119 can absorb condensate.

[0108] Regarding the assembly process of the atomizing core assembly 11 provided in the embodiments of this application, in some embodiments, it may be as follows: (1) The atomizing core 17 is assembled on the first sealing member 117, that is, one end of the atomizing core 17 is inserted into the first sealing member 117. The atomizing core 17 includes a heating element 116, a liquid guiding element 115, a support element 114 and an atomizing base 110 assembled together. (2) Place the liquid storage component 113 onto the atomizing core 17; (3) First seal a ring of food-grade special sealing wax on the atomizing outer cover 112 to form a hot melt part 111 to seal the liquid inlet hole 1121; (4) The atomizing cover 112 is fitted onto the liquid storage component 113; (5) Inject approximately 2 ml of aerosol matrix from the end of the liquid storage component 113 away from the first seal 117; (6) Finally, the second sealing member 118 and the first liquid suction member 119 are assembled in sequence.
