[0047] As shown in Figures 1 to 3 , Figure 8 , an atomizer 1000 is provided in the embodiment, which comprises a shell assembly 100, a base assembly 200, a sealing sleeve 300 and an atomizing core 600.

[0048] In some embodiments, the shell assembly 100 can include a first end 101 and a second end 102 distributed along an axial direction of the atomizer 1000. Here, the axial direction of the atomizer 1000 can refer to the extension direction of the central axis L. In addition, the first end 101 of the shell assembly 100 can be configured with an air guide tube 112 facing the second end 102. The air guide tube 112 can extend along the axial direction of the atomizer 1000 towards the second end 102.

[0049] In some embodiments, the base assembly 200 can be connected to the second end 102 of the shell assembly 100. The side of the base assembly 200 facing the first end 101 cooperates with the inner wall of the shell assembly 100 to define a liquid storage cavity 113, which can be used to store an atomization substrate. In addition, the side of the base assembly 200 facing the first end 101 is provided with an assembly groove 251. The base assembly 200 is also provided with a first liquid inlet hole 254, which respectively communicates with the assembly groove 251 and the liquid storage cavity 113.

[0050] In some embodiments, the sealing sleeve 300 can be sealingly inserted into the assembly groove 251. The side of the sealing sleeve 300 facing the first end 101 is provided with a receiving groove 360. An end of the air guide tube 112 facing the second end 102 can be sealingly inserted into the receiving groove 360. In addition, the sealing sleeve 300 is also provided with a second liquid inlet hole 330 communicating with the receiving groove 360.

[0051] In some embodiments, the atomization core 600 is fixedly installed in the receiving groove 360 of the sealing sleeve 300. The atomization core 600 can form a liquid path communication with the liquid storage cavity 113 through the second liquid inlet hole 330 and the first liquid inlet hole 254. In some embodiments, the atomization core 600 also has an atomization channel 630, which forms a gas path communication with the air guide tube 112.

[0052] During use, the atomization substrate in the liquid storage cavity 113 can enter the atomization core 600 through the first liquid inlet hole 254 and the second liquid inlet hole 330 in sequence, and be atomized by the atomization core 600 to generate an aerosol. The aerosol can be output from the atomizer 1000 through the atomization channel 630 and the air guide tube 112.

[0053] In the atomizer 1000 provided by the embodiments of the present application, the atomization core 600 does not need to be sleeved with an atomization tube, and a sealing member (i.e., the sealing sleeve 300) can simultaneously realize the sealing between the atomization core 600 and the base assembly 200, and the sealing between the air guide tube 112 and the base assembly 200. Therefore, the number of atomization tubes and the number of sealing members in the atomizer 1000 can be reduced, that is, the number of parts in the atomizer 1000 can be reduced, and thus the assembly efficiency of the atomizer 1000 can be improved, which is beneficial to realize the automatic assembly of the atomizer 1000 and further improve the assembly efficiency.

[0054] As Figures 1 to 3As shown, in some embodiments, the housing assembly 100 may include an oil cup 110 and a second liquid suction member 120.

[0055] The oil cup 110 may include a housing 111 and an air guide tube 112. The end of the air guide tube 112 facing the first end 101 may be integrally formed with the housing 111. The end of the housing 111 facing the second end 102 may protrude relative to the end of the air guide tube 112 facing the second end 102. Additionally, the end of the housing 111 facing the first end 101 has a fifth through hole 1111 that communicates with the air guide tube 112. In use, the air guide tube 112 can communicate with the nozzle in the atomizing device through the fifth through hole 1111.

[0056] In some embodiments, a liquid reservoir 113 may be formed in an oil cup 110, and the liquid reservoir 113 may be disposed around the periphery of the air guide tube 112. In the embodiments, the housing 111, the air guide tube 112, and the base assembly 200 may cooperate to define the liquid reservoir 113. The end of the liquid reservoir 113 facing the first end 101 may be a closed structure, and the end of the liquid reservoir 113 facing the second end 102 may be configured as an opening 114. During the assembly of the atomizer 1000, an atomizing matrix may be injected into the liquid reservoir 113 through the opening 114, and the base assembly 200 may also be installed at the opening 114.

[0057] In some embodiments, the second suction member 120 is disposed on the side of the oil cup 110 facing the first end 101. In use, the first end 101 of the housing assembly 100 can be used to connect to the suction nozzle, and the second suction member 120 can be used to absorb condensate generated at the suction nozzle location, which can reduce the probability of leakage problems.

[0058] In some embodiments, the oil cup 110 has an annular receiving groove 115 on the side facing the first end 101, and the receiving groove 115 may be arranged around the periphery of the fifth through hole 1111. The second liquid suction member 120 may have an annular structure and be disposed in the receiving groove 115.

[0059] In some embodiments, the second absorbent 120 may be made of absorbent cotton or the like.

[0060] like Figure 2 , Figures 4 to 6 As shown, in some embodiments, the base assembly 200 may include a base 210, a bracket 250, a seal 220, and a conductive electrode 230.

[0061] The base 210 may include an integral base plate 211 and a connecting portion 212. The connecting portion 212 may have a ring-shaped structure and protrude from one side of the base plate 211. In this embodiment, the connecting portion 212 may be inserted into the housing 111 and may be connected to the housing 111 by means of snap-fit ​​or screw connection. The base plate 211 may abut against the end face of the housing 111 facing the second end 102.

[0062] In some embodiments, the sealing member 220 can have a ring structure. The sealing member 220 can be arranged around the periphery of the connecting portion 212 and compressed between the connecting portion 212 and the inner wall of the shell 111. Thus, the sealing member 220 can seal the connection position of the base 210 and the shell 111, reducing the probability of liquid leakage.

[0063] In some embodiments, the bracket 250 is arranged on the side of the base 210 facing the first end 101. One end of the sealing member 220 facing the first end 101 can protrude away from the end of the connecting portion 212 facing away from the bottom plate 211. The end of the sealing member 220 protruding away from the connecting portion 212 can be inserted between the bracket 250 and the inner wall of the shell 111, and the sealing member 220 can be compressed between the bracket 250 and the inner wall of the shell 111 to seal the connection position of the bracket 250 and the shell 111, reducing the probability of liquid leakage.

[0064] In some embodiments, the base assembly 200 can include two conductive electrodes 230. One of the conductive electrodes 230 can be used as a positive electrode, and the other conductive electrode 230 can be used as a negative electrode.

[0065] In some embodiments, the conductive electrode 230 can include an integral contact portion 231 and an electrode column 232, and the contact portion 231 can be located at one end of the electrode column 232. The electrode column 232 can have a columnar structure. The electrode column 232 can be arranged through the bottom plate 211 and protrude away from the side of the bottom plate 211 facing the bracket 250. The electrode column 232 can be electrically connected to the atomization core 600 by a wire or the like.

[0066] In some embodiments, the contact portion 231 can have a plate structure. The contact portion 231 can be embedded on the side of the bottom plate 211 facing away from the connecting portion 212. The surface of the side of the contact portion 231 facing away from the electrode column 232 can be flush with the surface of the side of the bottom plate 211 facing away from the connecting portion 212. In use, the contact portion 231 can be in contact with the host in the atomization device for electrical connection, so that the host can control the operation of the atomization core 600 and provide power to the atomization core 600.

[0067] In some embodiments, the side of the bottom plate 211 facing the connecting portion 212 further protrudes a limiting protrusion 213. The limiting protrusion 213 is arranged around the periphery of the electrode column 232. Thus, the limiting protrusion 213 can provide a limiting function for the conductive electrode 230, reducing the possibility of the conductive electrode 230 shaking, thereby ensuring the stability and reliability of the connection between the conductive electrode 230 and the atomization core 600.

[0068] In some embodiments, the electrode column 232 can protrude away from the side of the limiting protrusion 213 opposite to the bottom plate 211 at the end away from the contact portion 231, and can be inserted into the support 250. Thus, the installation stability of the conductive electrode 230 can be further improved, and the connection stability and reliability between the conductive electrode 230 and the atomization core 600 can be ensured.

[0069] In some embodiments, the base assembly 200 further comprises a first liquid absorbing member 240 arranged on the side of the bottom plate 211 facing the support 250, and accommodated in the space formed by the connection portion 212 and the bottom plate 211. In use, the first liquid absorbing member 240 can be used to absorb condensed liquid and leaked atomization substrate, so as to reduce the possibility of further leakage of the atomization substrate and the condensed liquid outside the atomizer 1000.

[0070] As shown in FIGS. 1, 2 and 3, Figure 2 , Figures 7 to 10 In some embodiments, the support 250 can comprise an integrated support body 252 and an extension 253. The side of the support body 252 facing the base 210 can abut the side of the connection portion 212 facing away from the bottom plate 211. Thus, the base 210 can provide corresponding support function for the support 250, and can also provide limiting function for the support 250 parallel to the axial direction of the atomizer 1000. In addition, the surface of the side of the support body 252 can be fitted with the inner wall of the side of the housing 111 facing the liquid storage cavity 113. In embodiments, the part of the sealing member 220 protruding relative to the connection portion 212 can be inserted between the support body 252 and the inner wall of the housing 111, so as to seal the assembly position of the support 250 and the housing 111, and reduce the probability of liquid leakage.

[0071] In embodiments, the extension 253 is protrudingly arranged on the side of the support body 252 away from the base 210. In some embodiments, the assembly groove 251 can extend through the extension 253 along the axial direction of the atomizer 1000 and extend to the inside of the support body 252.

[0072] In some embodiments, the two opposite sides of the extension 253 can be provided with notches 2531. The outer wall of the extension 253 at the position of the notches 2531 can be arranged spaced apart from the inner wall of the housing 111. The outer wall of the extension 253 can refer to the surface of the extension 253 away from the assembly groove 251. Accordingly, the liquid storage cavity 113 can extend to the position of the notches 2531 of the extension 253, i.e., the liquid storage cavity 113 can extend between the extension 253 and the housing 111.

[0073] In some embodiments, the side of the extension 253 can be further provided with one, three or four or any other number of notches 2531.

[0074] In some embodiments, the outer wall of the extension 253 on the periphery can be spaced apart from the inner wall of the housing 111 on the side facing the liquid storage cavity 113. That is, part of the liquid storage cavity 113 can be arranged around the periphery of the extension 253.

[0075] In some embodiments, the side of the extension 253 facing the gap 2531 is configured as a slope 2533. The slope 2533 can gradually tilt away from the side of the assembly groove 251 from the side close to the first end 101 to the side close to the second end 102. Thus, when the support 250 is assembled in the oil cup 110, it is convenient to insert the extension 253 into the liquid storage cavity 113 filled with the atomized substrate, and the slope 2533 can also provide a guiding function for the atomized substrate in the liquid storage cavity 113, so that the atomized substrate moves to the space between the extension 253 and the housing 111.

[0076] In some embodiments, the first liquid inlet hole 254 can be arranged on the periphery of the extension 253, and the first liquid inlet hole 254 can be in communication with the gap 2531, so that the first liquid inlet hole 254 can be in communication with the liquid storage cavity 113. In embodiments, the extension 253 can be provided with one, two or three or any other number of first liquid inlet holes 254 corresponding to the position of each gap 2531.

[0077] In some embodiments, the inner wall of the first liquid inlet hole 254 can be configured with a first slope structure section 2541, which can be located on the side of the first liquid inlet hole 254 close to the first end 101. In embodiments, the first slope structure section 2541 can gradually tilt away from the first end 101 from the end away from the second liquid inlet hole 330 to the end close to the second liquid inlet hole 330. Thus, when the atomizer 1000 is inverted, the atomized substrate can be prevented from sticking to the first slope structure section 2541, thereby reducing the possibility of the atomized substrate entering the atomizing core 600 during storage and transportation of the atomizer 1000, and reducing the probability of the problem of the atomizing core and liquid leakage. During storage and transportation, the atomizer 1000 can be placed upside down. In addition, during use of the atomizer 1000, the first slope structure section 2541 can provide a guiding and draining function for the atomized substrate, which is beneficial to the smooth delivery of the atomized substrate through the first liquid inlet hole 254 to the atomizing core 600.

[0078] As Figure 2 , Figure 5 , Figures 7 to 10As shown, in some embodiments, the bracket 250 is further provided with a ventilation groove 255 in communication with the liquid storage cavity 113 and the external environment. During use of the atomizer 1000, the ventilation groove 255 can balance the air pressure in the liquid storage cavity 113, ensure that the atomized substrate in the liquid storage cavity 113 smoothly passes through the first liquid inlet hole 254 and the second liquid inlet hole 330 into the atomizing core 600, ensure the taste consistency during user suction, and also reduce the possibility of the atomizing core 600 being burnt out.

[0079] In some embodiments, the ventilation groove 255 can include at least one profiled segment 2551. Thus, the extension path of the ventilation groove 255 can be extended, and the possibility of the atomized substrate in the liquid storage cavity 113 leaking through the ventilation groove 255 can be reduced. In some embodiments, the profiled segment 2551 can be a lying U-shaped segment.

[0080] In some embodiments, the profiled segment 2551 can also be an S-shaped segment or a Z-shaped segment, etc.

[0081] In some embodiments, the ventilation groove 255 can include a connecting segment 2552 and one profiled segment 2551 in communication. The connecting segment 2552 can be provided on the side of the extension part 253 facing the abutting part 320, and the end of the connecting segment 2552 away from the profiled segment 2551 can be in communication with the liquid storage cavity 113. In embodiments, the side of the connecting segment 2552 away from the base assembly 200 can be covered and shielded by the abutting part 320, which can reduce the probability of the atomized substrate in the liquid storage cavity 113 entering the connecting segment 2552, and thus can reduce the possibility of the atomized substrate leaking out through the ventilation groove 255.

[0082] In embodiments, the profiled segment 2551 can be provided on the side wall and the bottom surface of the side of the assembly groove 251 facing the sealing sleeve 300. In embodiments, the inner wall of the assembly groove 251 can include a side wall provided around the side of the sealing sleeve 300 and a bottom surface located on the side of the sealing sleeve 300 close to the base 210. In embodiments, the end of the profiled segment 2551 away from the connecting segment 2552 can be in communication with the external environment.

[0083] In some embodiments, the ventilation groove 255 can also include a plurality of profiled segments 2551, which can be in communication in sequence and can be in communication between the connecting segment 2552 and the external environment.

[0084] In some embodiments, the bracket 250 further has a third through hole 256 which is in communication with the air exchange groove 255 and is located at one end of the bracket 250 which is close to the base 210. The base 210 can have an air inlet hole 214 which is in communication with the outside environment. The first liquid suction member 240 can have a fourth through hole 241 which is in communication with the air inlet hole 214. In addition, the bracket 250 and the base 210 can form an air flow channel 400 which is in communication with the fourth through hole 241 and the third through hole 256. Thus, the end of the air exchange groove 255 which is away from the liquid storage cavity 113 can be in communication with the outside environment through the third through hole 256, the air flow channel 400, the fourth through hole 241 and the air inlet hole 214 in sequence. During use, as the atomized substrate in the liquid storage cavity 113 is reduced, the gas in the outside environment can enter the liquid storage cavity 113 through the air inlet hole 214, the fourth through hole 241, the air flow channel 400 and the third through hole 256 in sequence, so as to balance the air pressure in the liquid storage cavity 113 and ensure that the atomized substrate in the liquid storage cavity 113 can be smoothly delivered to the atomization core 600 in the subsequent suction action.

[0085] As shown in Figure 2 , Figure 5 , Figures 8 to 10 In some embodiments, the bracket body 252 further has a second through hole 257 which is in communication with the air flow channel 400. The end of the sealing sleeve 300 which is close to the base assembly 200 can have a first through hole 350 which is opposite to the second through hole 257 and is in communication with the second through hole 257. The atomization channel 630 in the atomization core 600 can be in communication with the outside environment through the first through hole 350, the second through hole 257, the air flow channel 400, the fourth through hole 241 and the air inlet hole 214 in sequence. During the suction action, the outside airflow can smoothly enter the atomization core 600, and the generated aerosol can be delivered to the direction of the suction nozzle of the atomization device through the air guide tube 112.

[0086] As shown in Figure 2 , Figure 8 and Figure 9 In some embodiments, the sealing sleeve 300 can include an integrated sealing sleeve body 310 and an abutting portion 320. The sealing sleeve body 310 can be sealingly inserted into the assembly groove 251, which can reduce the probability of liquid leakage. The sealing sleeve body 310 can have a barrel-shaped structure, and a containing groove 360 can be formed in the sealing sleeve body 310 and is located at the first end 101.

[0087] In some embodiments, the inner wall of the assembly groove 251 is configured as a tapered surface. The tapered surface can gradually tilt away from the inner wall of the housing assembly 100 from the end close to the first end 101 to the end close to the second end 102, that is, the assembly groove 251 can have a reverse tapered shape. Thus, the sealing sleeve body 310 can be conveniently assembled into the assembly groove 251.

[0088] In some embodiments, the second liquid inlet hole 330 can be arranged on the side of the sealing sleeve body 310, and can be opposite and in communication with the first liquid inlet hole 254. An end of the second liquid inlet hole 330 away from the first liquid inlet hole 254 can be in communication with the atomization core 600. Thus, the atomization core 600 can be in communication with the liquid storage cavity 113 through the second liquid inlet hole 330 and the first liquid inlet hole 254 in sequence. The atomization substrate in the liquid storage cavity 113 can enter the atomization core 600 through the first liquid inlet hole 254 and the second liquid inlet hole 330 in sequence, and be heated and atomized by the atomization core 600 to generate aerosol.

[0089] In some embodiments, the same second liquid inlet hole 330 can be opposite and in communication with all the first liquid inlet holes 254 at the same gap 2531 position.

[0090] In some embodiments, each first liquid inlet hole 254 can be opposite and in communication with one second liquid inlet hole 330, and the second liquid inlet holes 330 communicated by different first liquid inlet holes 254 are different.

[0091] In some embodiments, the inner wall of the second liquid inlet hole 330 is configured with a second inclined surface structure section 331, which can be located on the side of the second liquid inlet hole 330 close to the first end 101. In some embodiments, the second inclined surface structure section 331 can gradually incline away from the first end 101 from the end away from the atomization core 600 to the end close to the atomization core 600. Thus, when the atomizer 1000 is inverted, the atomization substrate can be prevented from being hung on the second inclined surface structure section 331, thereby reducing the possibility of the atomization substrate entering the atomization core 600 during the storage and transportation of the atomizer 1000, and reducing the probability of the occurrence of the problems of the atomization core and liquid leakage. In addition, in the process of using the atomizer 1000, the second inclined surface structure section 331 can provide a guiding and draining function for the atomization substrate, which is beneficial to the smooth passage of the atomization substrate through the second liquid inlet hole 330, so as to flow towards the atomization core 600.

[0092] In some embodiments, the first liquid inlet hole 254 has a first central axis L1 perpendicular to the axial direction of the atomizer 1000, and the second liquid inlet hole 330 has a second central axis L2 perpendicular to the axial direction of the atomizer 1000. In some embodiments, the distance between the first central axis L1 and the first end 101 is less than the distance between the second central axis L2 and the first end 101.

[0093] As Figure 1 , Figure 2 , Figures 9 to 12As shown, when the atomizer 1000 is in a storage or transportation state, the atomizer 1000 can be inverted, i.e., the second end 102 of the shell assembly 100 is located above the first end 101. When the atomizer 1000 is inverted, the first liquid inlet hole 254 can be arranged close to the top of the atomizer 1000. In the embodiment, when the atomizer 1000 is inverted, the liquid level of the atomization substrate in the liquid storage cavity 113 can be located on the side of the first liquid inlet hole 254 close to the first end 101, i.e., the liquid level of the atomization substrate is lower than the first liquid inlet hole 254, which can reduce the probability of the atomization substrate entering the first liquid inlet hole 254. At the same time, the central axis L1 of the first liquid inlet hole 254 is lower than the second central axis L2 of the second liquid inlet hole 330, which can further reduce the possibility of the atomization substrate entering the second liquid inlet hole 330 through the first liquid inlet hole 254, and thus can reduce the possibility of the atomization substrate entering the atomization core 600, and reduce the risk of core sticking (i.e., the atomization substrate sticking to the atomization core 600) and liquid leakage of the atomizer 1000 during storage and transportation.

[0094] In some embodiments, the distance between the first central axis L1 and the first end 101 can also be equal to the distance between the second central axis L2 and the first end 101.

[0095] As shown in Figure 2 , Figure 8 and Figure 9 , in some embodiments, the side of the sealing sleeve body 310 away from the containing groove 360 is provided with a first sealing ring portion 341, a second sealing ring portion 342, and a plurality of sealing ribs 343. The first sealing ring portion 341 is located on the side of the second liquid inlet hole 330 facing the first end 101. The second sealing ring portion 342 is located on the side of the second liquid inlet hole 330 facing the second end 102. The sealing ribs 343 can extend along the axial direction of the atomizer 1000 and are connected between the first sealing ring portion 341 and the second sealing ring portion 342. In addition, on the circumferential direction of the sealing sleeve 300, one sealing rib 343 is arranged on each side of the second liquid inlet hole 330. Accordingly, the sealing ribs 343 located on both sides of the same second liquid inlet hole 330 can cooperate with the first sealing ring portion 341 and the second sealing ring portion 342 to form a sealing ring structure 340 surrounding the second liquid inlet hole 330, and the side of the sealing ring structure 340 away from the sealing sleeve body 310 can abut against the inner wall of the assembly groove 251 and be in interference fit. Thus, the sealing between the sealing sleeve 300 and the inner wall of the assembly groove 251 can be achieved, and the probability of liquid leakage can be reduced. At the same time, the relative fixation between the sealing sleeve 300 and the support 250 can also be achieved.

[0096] As shown in Figure 2 , Figures 7 to 9As shown, in some embodiments, the abutment portion 320 can be connected to one end of the sealing sleeve body 310 towards the first end 101. The abutment portion 320 can protrude from the side of the sealing sleeve body 310 away from the accommodating groove 360 along the radial direction of the atomizer 1000. The radial direction of the atomizer 1000 can refer to any direction perpendicular to the axial direction of the atomizer 1000. Accordingly, the abutment portion 320 can have a ring-like structure.

[0097] In some embodiments, the abutment portion 320 can abut against the end face of the extension portion 253 away from the bracket body 252. Thus, the assembly gap between the sealing sleeve 300 and the bracket 250 can be shielded by the abutment portion 320, reducing the possibility of the atomized substrate in the liquid storage cavity 113 entering the assembly gap between the sealing sleeve 300 and the bracket 250, further reducing the probability of the liquid leakage problem, and improving the sealing effect.

[0098] In some embodiments, one of the side of the extension portion 253 towards the abutment portion 320 and the side of the abutment portion 320 towards the extension portion 253 is provided with at least one positioning groove 2532, and the other is provided with at least one positioning protrusion 321. The at least one positioning protrusion 321 is correspondingly positioned and inserted into the at least one positioning groove 2532, so that the positioning and installation of the sealing sleeve 300 and the bracket 250 can be achieved, and the assembly efficiency is improved. At the same time, the relative rotation of the sealing sleeve 300 and the bracket 250 during the assembly of the atomizer 1000 can be prevented, and the accurate alignment and communication of the second liquid inlet hole 330 and the first liquid inlet hole 254 are ensured.

[0099] In some embodiments, the side of the extension portion 253 towards the abutment portion 320 can be provided with two positioning grooves 2532. The two positioning grooves 2532 can be symmetrically arranged about the central axis L of the atomizer 1000. The side of the abutment portion 320 towards the extension portion 253 is provided with two positioning protrusions 321. The two positioning protrusions 321 are correspondingly positioned and inserted into the two positioning grooves 2532.

[0100] In some embodiments, the side of the extension portion 253 towards the abutment portion 320 can also be provided with one, three, four or any other number of positioning grooves 2532. The side of the abutment portion 320 towards the extension portion 253 can be provided with positioning protrusions 321 equal in number to the positioning grooves 2532. When the positioning grooves 2532 and the positioning protrusions 321 are provided in multiple groups, the multiple positioning protrusions 321 can be correspondingly positioned and inserted into the multiple positioning grooves 2532.

[0101] In some embodiments, the positioning grooves 2532 can also be provided on the side of the abutment portion 320 towards the extension portion 253. The positioning protrusions 321 can protrude from the side of the extension portion 253 towards the abutment portion 320.

[0102] AsFigure 2 , Figure 8 and Figure 9 As shown, in some embodiments, the atomizing core 600 can be disposed in the receiving groove 360 ​​within the sealing sleeve body 310. Furthermore, the surface of the atomizing core 600 facing the sealing sleeve body 310 can be interference-fitted with the inner wall of the receiving groove 360, allowing the atomizing core 600 to be relatively fixed to the sealing sleeve 300. Additionally, the end face of the atomizing core 600 facing the base 210 can abut against the bottom surface of the sealing sleeve body 310 on the side opposite to the base 210.

[0103] In some embodiments, the atomizing core 600 may include a solid porous substrate 610 and a heating element 620. The solid porous substrate 610 may have a tubular structure, and an atomization channel 630 may be formed within the solid porous substrate 610. The heating element 620 may be disposed within the solid porous substrate 610. In use, the solid porous substrate 610 can obtain the atomizing matrix from the liquid storage chamber 113 through the first liquid inlet 254 and the second liquid inlet 330, and the heating element 620 heats and atomizes the atomizing matrix to generate an aerosol. In some embodiments, the atomizing core 600 may be a ceramic atomizing core.

[0104] In some embodiments, the atomizing core 600 may also be a solid atomizing core such as a metal atomizing core or a glass atomizing core.

[0105] like Figure 1 , Figure 2 , Figure 8 , Figure 9 , Figure 11 and Figure 12 As shown, in some embodiments, the end of the vent tube 112 facing the second end 102 can be inserted into the assembly groove 251 and press-fitted with the side of the sealing sleeve body 310 away from the inner wall of the assembly groove 251 to form a sealed connection. Correspondingly, the end of the sealing sleeve 300 facing the first end 101 and the end of the extension 253 facing the first end 101 can be inserted into the liquid storage cavity 113 and can occupy part of the space of the liquid storage cavity 113.

[0106] During the assembly of the atomizer 1000, the housing assembly 100 can be placed upside down, and the atomization substrate can be injected into the liquid storage cavity 113 from the opening 114 of the oil cup 110. When the liquid level of the atomization substrate reaches the first preset liquid level M, the injection of the atomization substrate can be stopped. Then, the assembled support 250 can be installed in the second end 102 of the housing assembly 100 together with the sealing sleeve 300 and the atomization core 600. During the installation, the abutting portion 320 and the extension portion 253 of the sealing sleeve 300 are gradually inserted into the liquid storage cavity 113, and the atomization substrate in the liquid storage cavity 113 is extruded, and the liquid level of the atomization substrate gradually rises to the second preset liquid level N. Thus, the gas in the liquid storage cavity 113 can be gradually discharged, the gas in the liquid storage cavity 113 is reduced, and the remaining space in the liquid storage cavity 113 is reduced. In turn, the shaking amplitude of the atomization substrate during transportation and storage can be reduced, and the probability of liquid leakage can be reduced.

[0107] In some embodiments, the sealing sleeve body 310 can be substantially inverted conical, and the inner wall of the accommodating groove 360 can be inclined. On the one hand, the atomization core 600 can be conveniently installed in the accommodating groove 360, and on the other hand, the air guide pipe 112 can be conveniently inserted into the accommodating groove 360.

[0108] In the embodiment, the end face of the air guide pipe 112 toward the second end 102 can abut against the end face of the atomization core 600 toward the first end 101. Thus, the atomization core 600 can be further fixed.

[0109] As shown in Figure 1 , Figure 2 and Figure 5 , in some embodiments, the atomizer 1000 can further include a first sealing plug 510 and a second sealing plug 520. When the atomizer 1000 is in a non-use state, the first sealing plug 510 can be sealingly inserted into the fifth through hole 1111 and the end of the air guide pipe 112 away from the base assembly 200, and the second sealing plug 520 can be sealingly inserted into the air inlet hole 214. Thus, when the atomizer 1000 is in a non-use state, the liquid storage cavity 113 can be isolated from the external environment, and the probability of liquid leakage and core sticking can be reduced.

[0110] As shown in Figure 1 , Figure 2 and Figure 8As shown, in the process of assembling the atomizer 1000, the sealing sleeve 300 can be installed into the assembly groove 251 of the support 250, and then the atomization core 600 can be installed into the accommodating groove 360 of the sealing sleeve 300. In addition, the base 210, the sealing member 220, the first liquid suction member 240, and the conductive electrode 230 can be assembled. Then, the assembled support 250 together with the sealing sleeve 300 and the atomization core 600 can be connected to the end of the base 210 provided with the sealing member 220. Then, the assembled base assembly 200 together with the atomization core 600 and the like can be installed at the second end 102 of the shell assembly 100, and in this process, the air guide pipe 112 can be inserted into the assembly groove 251 and sealingly connected to the side of the sealing sleeve 300 away from the inner wall of the assembly groove 251. When assembled in place, the connecting portion 212 can be clamped with the shell 111, and the bottom plate 211 can abut against the end face of the end of the shell 111 facing the second end 102. In this way, the assembly of the atomizer 1000 can be achieved. Accordingly, the atomizer 1000 provided in the embodiments of the present application can facilitate automatic assembly, and thus the production efficiency of the atomizer 1000 can be improved, and the production capacity can be improved.

[0111] In the embodiments, an atomization device is also provided, which can include a host and the atomizer 1000 provided in the embodiments. The atomizer 1000 can be installed in the host and electrically connected with the host.
