[0033] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0034] An electronic atomizer is used to store an aerosol-generating substrate and atomize it to form an aerosol for inhalation. This electronic atomizer can be used in various fields, such as medical treatment, cosmetics, and recreational smoking. In one embodiment, the electronic atomizer can be used in an electronic aerosolization device to atomize an aerosol-generating substrate and generate an aerosol for inhalation. The following embodiments use this recreational smoking example. Of course, in other embodiments, the electronic atomizer can also be used in hairspray devices to atomize hair styling spray, or in devices for treating upper and lower respiratory system diseases to atomize medical medications.

[0035] Please refer to Figure 1 and Figure 2 The present invention provides an electronic atomizer 100, comprising a nozzle 10, a housing 20, and a sealing assembly 30. The housing 20 is connected to the nozzle 10 and encloses an oil storage chamber 211. An oil filling hole 212 is formed at one end of the housing 20 away from the nozzle 10, and the oil filling hole 212 is connected to the oil storage chamber 211.

[0036] The shape of the housing 20 can be roughly rectangular or cylindrical, without limitation. The wall thickness of the housing 20 can be roughly uniform throughout. The housing 20 can be a one-piece structure, and the one-piece molding process can be stamping, casting, etc., without limitation. The housing 20 can also be a split structure, and the various parts of the housing 20 can be connected and fixed by welding, bonding, clamping, screwing, etc.

[0037] The shape of the oil storage chamber 211 is not particularly limited. The oil storage chamber 211 is used to receive the liquid to be atomized injected from the oil injection hole 212 .

[0038] Regarding the specific shape of the suction nozzle 10, any feasible solution can be referred to, and the embodiment of the present invention does not impose specific restrictions. The shell 20 and the suction nozzle 10 can be an integral structure or a split structure, and the connection method between the suction nozzle 10 and the shell 20 can be welding, bonding, snap connection, screw connection, magnetic connection, etc., without limitation. In the embodiment of the present invention, the oil filling hole 212 is located at the end of the shell 20 away from the suction nozzle 10, so the suction nozzle 10 and the shell 20 can be pre-assembled together before oiling, and there is no need to package the suction nozzle 10 and the shell 20 separately, which can save costs. In addition, compared with the solution of injecting oil from one side of the suction nozzle 10 into the shell 20 in the prior art, in batch production, the embodiment of the present invention does not need to pre-install the suction nozzle 10 on the shell 20 after oiling and then perform batch capping, so the oiling work efficiency is high.

[0039] The sealing assembly 30 is connected to the housing 20 and moves relative to the housing 20 to switch from a first state to a second state. In the first state, the oil filling hole 212 is exposed; in the second state, the sealing assembly 30 closes the oil filling hole 212.

[0040] The sealing assembly 30 can be any sealing assembly 30 that can seal the oil filling hole 212, and can be a single part or multiple parts, without limitation. The connection method of the sealing assembly 30 relative to the housing 20 can be sliding, rotating, or any other feasible movable connection method, without limitation.

[0041] The sealing assembly 30 can be pre-installed on the housing 20. Before the electronic atomizer 100 is filled with oil, that is, in the first state, the oil filling hole 212 is exposed, and the sealing assembly 30 is connected to the housing 20 without blocking the oil filling hole 212. The liquid to be atomized can be injected into the oil storage chamber 211 from the oil filling hole 212 by manual or machine oil filling. After the electronic atomizer 100 is filled with oil, the sealing assembly 30 moves relative to the housing 20 to switch from the first state to the second state. In the second state, the sealing assembly 30 closes the oil filling hole 212, making it easier for the user to inhale, and the liquid to be atomized in the oil storage chamber 211 will not leak out from the oil filling hole 212.

[0042] Optionally, after the liquid to be atomized in the oil storage chamber 211 is completely inhaled by the user, the sealing assembly 30 can be withdrawn from the oil filling hole 212, and the electronic atomizer 100 can be refilled with oil and used repeatedly to avoid waste.

[0043] The electronic atomizer 100 in the embodiment of the present invention is provided with a suction nozzle 10, a shell 20 and a sealing assembly 30. An oil filling hole 212 is also opened at an end of the shell 20 away from the suction nozzle 10. The sealing assembly 30 moves relative to the shell 20 to switch from a first state to a second state. In the second state, the sealing assembly 30 closes the oil filling hole 212. The suction nozzle 10 and the shell 20 are pre-installed together and do not need to be packaged separately, which can save costs. There is no need to pre-install the suction nozzle 10 on the shell 20 after oiling and then press the cap. The sealing assembly 30 pre-installed on the shell 20 can be used to close the oil filling hole 212, and the oil filling efficiency is high.

[0044] First define the direction. Please refer to Figure 2 , X is the first direction, and Y is the second direction. The first direction X is perpendicular to the second direction Y. Optionally, when the electronic atomizer 100 is in a vertical position with the nozzle 10 facing upward, that is, when the nozzle 10 is at the end of the electronic atomizer 100 away from the ground in the direction of gravity, the second direction Y is parallel to the direction of gravity.

[0045] In one embodiment, reference Figure 1 、 Figure 2 and Figure 3The sealing assembly 30 includes a first movable member 31 and a second movable member 32. The first movable member 31 is movably connected to the housing 20 in the first direction X. The first movable member 31 is used to close the oil filling hole 212 in the second state. The second movable member 32 is movably connected to the housing 20 and is used to move relative to the housing 20 to drive the first movable member 31 to move relative to the housing 20. In the second state, the second movable member 32 is fixedly connected to the housing 20.

[0046] Optionally, the first movable member 31 and the second movable member 32 are both elastic members. The material of the first movable member 31 and the second movable member 32 can be silicone rubber, nitrile rubber (NBR), fluororubber, polytetrafluoroethylene (PTFE), etc., without limitation.

[0047] The movable connection mode of the first movable part 31 with the shell 20 in the first direction X can be a sliding connection, a rotating connection or any feasible movable connection mode or a combination of multiple movable connection modes. For example, the first movable part 31 is slidably and rotationally connected to the shell 20 in the first direction X, etc., and the embodiment of the present utility model does not make specific restrictions.

[0048] Similarly, the movable connection method of the second movable member 32 and the housing 20 can be referred to the movable connection method of the first movable member 31 and the housing 20 described above, and will not be repeated here. The second movable member 32 is also movably connected to the first movable member 31, so that the movement of the second movable member 32 drives the first movable member 31 to move relative to the housing 20.

[0049] In the first state, in orthographic projection along the Y direction, a gap exists between the first movable member 31 and the oil filling hole 212, facilitating the insertion of an oiling tool (e.g., an oiling needle) into the oil filling hole 212 to inject oil into the oil reservoir 211. In the second state, the second movable member 32 is securely connected to the housing 20 to prevent the sealing assembly 30 from becoming dislodged during transportation and use, thereby preventing oil leakage. The connection between the second movable member 32 and the housing 20 can be by means of a snap-on connection, a threaded connection, a magnetic connection, or the like, without limitation.

[0050] The sealing assembly 30 includes a first movable member 31 and a second movable member 32. The second movable member 32 is used to move relative to the housing 20 to drive the first movable member 31 to move relative to the housing 20 in the first direction X. In the second state, the first movable member 31 closes the oil filling hole 212, and the second movable member 32 is fixedly connected to the housing 20. The sealing assembly 30 can close the oil filling hole 212 to prevent oil leakage, and the connection between the sealing assembly 30 and the housing 20 is stable and not easy to fall out.

[0051] In one embodiment, Figure 3 and Figure 4As shown, the shell 20 includes an oil storage shell 21 and a connecting portion 22. The oil storage shell 21 is connected to the suction nozzle 10 and encloses an oil storage cavity 211. An oil filling hole 212 is provided at one end of the oil storage shell 21 away from the suction nozzle 10. The first movable part 31 is slidably connected to the connecting portion 22 in a first direction X, and the second movable part 32 is movably connected to the connecting portion 22 in a second direction Y.

[0052] Optionally, the connecting portion 22 is connected to the end of the oil storage shell 21 away from the suction nozzle 10. The oil storage shell 21 and the connecting portion 22 can be an integral structure or a split structure, and the oil storage shell 21 and the connecting portion 22 are connected and fixed by welding, bonding, clamping, screwing, riveting, magnetic connection, etc., without limitation.

[0053] The movable connection between the second movable member 32 and the connecting portion 22 may be a sliding connection, a rotational connection, or any other feasible movable connection method, without limitation. For example, the second movable member 32 may be slidably connected to the connecting portion 22, and the second movable member 32 slides relative to the connecting portion 22 to drive the first movable member 31 to slide relative to the connecting portion 22 in the first direction X; or the second movable member 32 may be rotationally connected to the connecting portion 22, and the second movable member 32 rotates relative to the connecting portion 22 to drive the first movable member 31 to slide relative to the connecting portion 22 in the first direction X, without limitation.

[0054] By setting the housing 20 to include an oil storage shell 21 and a connecting part 22, the first movable part 31 is slidably connected to the connecting part 22 in the first direction X, and the second movable part 32 is movably connected to the connecting part 22. The movement of the second movable part 32 relative to the connecting part 22 drives the first movable part 31 to slide relative to the connecting part 22 in the first direction X to close the oil filling hole 212. The sealing method is simple and efficient. The first movable part 31 and the second movable part 32 can both be pre-installed on the housing 20, reducing the oil filling process and improving the oil filling efficiency.

[0055] In one embodiment, Figure 2 As shown, the connecting portion 22 defines a sliding hole 221 along the first direction X. At least a portion of the first movable member 31 is received in the sliding hole 221 and is slidably connected to the inner wall of the sliding hole 221. The connecting portion 22 also defines a sliding groove 222 that communicates with the sliding hole 221. The second movable member 32 is slidably connected to the inner wall of the sliding groove 222 in the second direction Y.

[0056] The shape of the sliding hole 221 can be circular, square, triangular, regular polygonal, etc., and the shape of the sliding hole 221 corresponds to the cross-sectional shape of the first movable member 31 along the first direction X, and is not particularly limited. In the first state, at least a portion of the first movable member 31 is contained within the sliding hole 221. In the second state, the first movable member 31 seals the oil filling hole 212, and the first movable member 31 can slide out of the sliding hole 221 or remain at least partially contained within the sliding hole 221, and is not particularly limited.

[0057] Optionally, in a cross section taken in the first direction X, the first movable member 31 and the inner wall of the sliding hole 221 are both circular, and the outer diameter of the first movable member 31 can be the same as the inner diameter of the sliding hole 221, that is, the outer peripheral wall of the first movable member 31 and the inner wall of the sliding hole 221 are in close contact. Alternatively, the inner diameter of the first movable member 31 is slightly larger than the inner diameter of the sliding hole 221. Since the first movable member 31 is an elastic member, the first movable member 31 and the inner wall of the sliding hole 221 are in elastic contact. When subjected to pressure from the second movable member 32, the first movable member 31 can overcome the inner wall of the sliding hole 221 and slide in the first direction X to close the oil filling hole 212. When not subjected to pressure from the second movable member 32, the first movable member 31 will not move around in the sliding hole 221, thereby preventing the first movable member 31 from moving in the first direction X and blocking the oil filling hole 212 when no oil is injected.

[0058] The cross-sectional shape of the sliding groove 222 in the second direction Y can be circular, square, triangular, irregular polygonal, etc. The shape of the sliding groove 222 can correspond to the cross-sectional shape of the second movable part 32 along the second direction Y, and there is no specific limitation.

[0059] Optionally, the second movable member 32 is slidably connected to at least one inner wall surface of the sliding groove 222. In a specific embodiment, Figure 3 and Figure 4 As shown, the sliding groove 222 includes three side walls connected one by one. In the positive projection of the second direction Y, the side wall of the sliding groove 222 is roughly U-shaped, and the opening of the U-shape faces away from the oil filling hole 212. The second movable part 32 is slidingly connected to the three side walls of the sliding groove 222, and the connection is stable and not easy to fall out.

[0060] By arranging that at least a portion of the first movable member 31 is accommodated in the sliding hole 221 of the connecting portion 22 and is slidably connected to the inner wall of the sliding hole 221, the second movable member 32 is slidably connected to the inner wall of the sliding groove 222 of the connecting portion 22. When the second movable member 32 slides relative to the inner wall of the sliding groove 222 in the second direction Y, it can drive the first movable member 31 to slide relative to the inner wall of the sliding hole 221 in the first direction X to close the oil filling hole 212. The sealing method is simple and efficient.

[0061] In one embodiment, Figure 4 and Figure 5 As shown, the second movable part 32 includes a main body 321 and a first matching portion 322. The first matching portion 322 is connected to the main body 321 and protrudes from the outer surface of the main body 321. The main body 321 is accommodated in the sliding groove 222. The side wall of the sliding groove 222 is provided with a second matching portion. The first matching portion 322 and the second matching portion are matched and connected.

[0062] Optionally, one of the first mating portion 322 and the second mating portion is a protrusion and the other is a groove, without limitation. In the following embodiments, the first mating portion 322 is a protrusion and the second mating portion is a receiving groove 223. At least a portion of the protrusion 322 is received in the receiving groove 223.

[0063] The second movable member 32 can be an integral structure, and the integral molding process can be injection molding, molding, etc., without limitation. The second movable member 32 can also be a split structure, and the main body 321 and the first matching portion 322 can be connected and fixed by bonding, clamping, screwing, etc.

[0064] The first mating portion 322 can be one or more, without limitation. In a specific embodiment, the first mating portions 322 are two and strip-shaped, and the main body 321 includes two surfaces facing each other in a third direction, which is perpendicular to the first direction X and the second direction Y. Each of the two facing surfaces of the main body 321 is provided with a first mating portion 322. Alternatively, the first mating portions 322 are multiple and block-shaped, and at least one surface of the main body 321 is provided with multiple first mating portions 322 spaced apart along the second direction Y. The multiple first mating portions 322 can be spaced equidistantly or unequally, without limitation.

[0065] The sidewalls of the sliding groove 222 define a receiving groove 223 along the second direction Y. The receiving groove 223 includes two sidewalls that oppose each other in the first direction X, and the sidewalls of the receiving groove 223 are parallel to the second direction Y. The bottom wall of the receiving groove 223 can be perpendicular to the second direction Y or at an angle thereto, without limitation. The first engaging portion 322 abuts against at least one sidewall of the receiving groove 223. When the second movable member 32 slides relative to the connecting portion 22, the first engaging portion 322 slides relative to the sidewall of the receiving groove 223.

[0066] By setting the second movable part 32 to include a main body 321 and a first matching part 322, the main body 321 is accommodated in the sliding groove 222, and at least a part of the first matching part 322 is accommodated in the receiving groove 223 opened on the side wall of the sliding groove 222, the contact area between the second movable part 32 and the connecting part 22 can be increased, and the connection between the second movable part 32 and the connecting part 22 is more stable. During the assembly and transportation process, the second movable part 32 is not easy to fall out of the sliding groove 222.

[0067] In one embodiment, Figure 4 and Figure 5 As shown, the second movable member 32 further includes a first engaging portion 323, which is connected to the first matching portion 322. The first engaging portion 323 is closer to the end of the second movable member 32 away from the bottom wall of the sliding groove 222 than the end of the second movable member 32 closer to the bottom wall of the sliding groove 222. The second matching portion 322 is provided with a second engaging portion. In the second state, the first engaging portion 323 is engaged and connected with the second engaging portion. One of the first engaging portion 323 and the second engaging portion is a protrusion and the other is a groove, without limitation. In the following embodiments, the first engaging portion 323 is a protrusion and the second engaging portion is a connecting groove 224.

[0068] The first engaging portion 323, the first mating portion 322, and the main body 321 can be integral or separate, without limitation. The first engaging portion 323 can be shaped like a block, a column, a hemispherical shape, etc., without limitation. The inner wall of the engaging groove 224 can be shaped to correspond to the first engaging portion 323, without limitation.

[0069] The number of the first clamping portion 323 can be one or more, without limitation. In a specific embodiment, there are two first clamping portions 323 and two first matching portions 322 , and each first matching portion 322 is provided with one first clamping portion 323 .

[0070] Optionally, in the first state, that is, before oil is injected, at least part of the second movable member 32 is exposed from the connecting portion 22, and the first clamping portion 323 is exposed from the connecting portion 22; in the second state, that is, after oil injection is completed, the second movable member 32 slides toward the bottom wall of the sliding groove 222 so that the second movable member 32 is completely accommodated in the sliding groove 222. At this time, the first clamping portion 323 is accommodated in the clamping groove 224, so that the second movable member 32 is connected and fixed to the connecting portion 22.

[0071] In another embodiment, two first engaging portions 323 are spaced apart on a first engaging portion 322, and two engaging grooves 224 are correspondingly defined on the sidewalls of the receiving slot 223. In the first state, one first engaging portion 322 closer to the bottom wall of the sliding slot 222 is received in the engaging groove 224 on the bottom wall farther from the sliding slot 222, while the other first engaging portion 323 is exposed from the connecting portion 22. In the second state, one first engaging portion 322 closer to one end of the bottom wall of the sliding slot 222 is received in the engaging groove 224 closer to the bottom wall of the sliding slot 222, while the other first engaging portion 322 is received in the engaging groove 224 on the bottom wall farther from the sliding slot 222. With this arrangement, the second movable member 32 is securely engaged with the connecting portion 22 in both the first and second states, making it difficult for the second movable member 32 to disengage and maintaining a stable connection.

[0072] By setting the second movable part 32 to also include a first clamping part 323, the second matching part is provided with a second clamping part. In the second state, the first clamping part 323 is matched and connected with the second clamping part. After the oil filling is completed, the second movable part 32 can be connected and fixed to the connecting part 22. The second movable part 32 is not easy to fall out, thereby avoiding oil leakage.

[0073] In one embodiment, Figure 4 As shown, the connecting portion 22 also includes a guide surface 225, which is located on the side of the clamping groove 224 away from the bottom wall of the sliding groove 222 in the second direction Y. The guide surface 225 has an angle with the second direction Y. In the direction from the bottom wall of the sliding groove 222 to the end of the connecting portion 22 away from the bottom wall of the sliding groove 222, the guide surface 225 and the side wall of the receiving groove 223 are flared.

[0074] Optionally, the included angle α between the guide surface 225 and the second direction Y satisfies the following conditions: 45°≤α≤70°. Specifically, the included angle α can be 45°, 50°, 55°, 60°, 65°, 70°, etc., without limitation. Optionally, the guide surface 225 and the bottom wall of the sliding groove 222 are oriented in the same direction.

[0075] Optionally, the guide surface 225 connects an end surface of the connecting portion 22 away from the bottom wall of the sliding groove 222 and a side wall surface of the receiving groove 223. The guide surface 225 and the side wall surface of the engaging groove 224 can be connected or separated by a certain distance, without limitation. Optionally, the guide surface 225 and the side wall surface of the engaging groove 224 are smoothly connected.

[0076] By setting the connecting portion 22 to also include a guide surface 225, the guide surface 225 guides the sliding of the first clamping portion 323, making it easier for the first clamping portion 323 to enter the clamping groove 224, and also preventing the connection between the clamping groove 224 and the side wall of the receiving groove 223 from scratching the first clamping portion 323.

[0077] In one embodiment, Figure 2 、 Figure 4 and Figure 5 As shown, the second movable member 32 includes a first end face 324 facing the bottom wall of the sliding groove 222 in the second direction Y, and a first angle A is formed between the first end face 324 and the first direction X, satisfying: 20°≤A≤70°; and / or, a second angle B is formed between the bottom wall of the sliding groove 222 and the first direction X, satisfying: 20°≤B≤70°; and / or, the first movable member 31 includes a second end face 311 slidably connected to the first end face 324, and a third angle C is formed between the second end face 311 and the first direction X, satisfying: 20°≤C≤70°.

[0078] Optionally, the value of the first angle A can be specifically 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, etc., without limitation. Optionally, the value of the second angle B can be specifically 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, etc., without limitation. Optionally, the value of the third angle C can be specifically 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, etc., without limitation. Optionally, the values ​​of the first angle A, the second angle B, and the third angle C are the same.

[0079] By setting the first angle A between the first end face 324 and the first direction X to satisfy 20°≤A≤70°, and / or, the second angle B between the bottom wall of the sliding groove 222 and the first direction X to satisfy 20°≤B≤70°, and / or, the third angle C between the second end face 311 and the first direction X to satisfy 20°≤C≤70°, when the first end face 324 slides relative to the bottom wall of the sliding groove 222, the second movable member 32 will not move relative to the connecting portion 22 in the first direction X, and will only slide relative to the connecting portion 22 in the second direction Y, so as to push the first movable member 31 to slide relative to the connecting portion 22 in the first direction X. When the second movable member 32 slides to the second state, it can be completely accommodated in the sliding groove 222, with simple transmission and beautiful appearance.

[0080] In one embodiment, Figure 3 and Figure 4 As shown, the housing 20 further includes an oil filling portion 23, which defines an oil filling groove 231 that communicates with the oil filling hole 212. The electronic atomizer 100 further includes a sealing member 40, which is received in the oil filling groove 231 and defines a connecting groove 41 that communicates with both the oil filling hole 212 and the sliding hole 221. In the second state, at least a portion of the first movable member 31 extends into the connecting groove 41 and abuts against the inner wall of the connecting groove 41 to seal the oil filling hole 212.

[0081] Optionally, the material of the sealing member 40 may be silicone rubber, nitrile rubber (NBR), fluororubber, polytetrafluoroethylene (PTFE), etc., without limitation.

[0082] Optionally, the shape of the sealing member 40 may be square, circular, rectangular, polygonal, etc., without limitation. The shape of the sidewalls of the oil filling groove 231 may correspond to the shape of the sealing member 40, without limitation.

[0083] Optionally, in the orthographic projection along the second direction Y, the area of ​​the connection between the connecting groove 41 and the sliding hole 221 is slightly smaller than the cross-sectional area of ​​the first movable member 31. That is, in the absence of an external force (for example, an extrusion force exerted on the first movable member 31 when the second movable member 32 is pressed to slide toward the bottom wall of the sliding groove 222), the first movable member 31 will not slide from the sliding hole 221 into the connecting groove 41, thereby preventing the first movable member 31 from sliding into the connecting groove 41 and blocking the oil filling hole 212 when no oil is injected. During the process of switching the sealing assembly 30 from the first state to the second state, the first movable member 31 is squeezed by the second movable member 32 and moves toward the oil filling hole 212. The first movable member 31 is slightly deformed by the force so as to pass through the sliding hole 221 and enter the connecting groove 41. In the second state, the first movable member 31 elastically abuts against the sealing member 40 to close the oil filling hole 212.

[0084] By providing the oil filling portion 23 and the sealing member 40 , at least a portion of the first movable member 31 extends into the connecting groove 41 and abuts against the inner wall of the connecting groove 41 to close the oil filling hole 212 . The sealing method is simple, the sealing effect is good, and oil leakage is not easy.

[0085] In one embodiment, Figure 2 and Figure 4 As shown, the electronic atomizer 100 further includes an atomizer core 50, and the shell 20 further includes an atomizer portion 24. The atomizer portion 24 is provided with an oil inlet 241, which is communicated with the oil storage chamber 211. The atomizer core 50 closes the oil inlet 241. The shell 20 further has an air flow channel 25, which communicates with the nozzle 10 and the atomizer core 50.

[0086] Optionally, the atomizing portion 24 is provided on a side of the oil filling portion 23 away from the connecting portion 22. The shape of the oil inlet 241 can be circular, square, rectangular, triangular, regular polygonal, etc., without specific limitation.

[0087] The atomizer core 50 is a commonly used atomizer in the art, such as a ceramic atomizer core, a cotton core atomizer core, etc. It can be a single heating wire atomizer core, a double heating wire atomizer core, a multi-heating wire atomizer core, etc., without specific limitation.

[0088] Optionally, there can be one or more atomizer cores 50. Multiple atomizer cores 50 can work independently or be connected in parallel for ease of control. Multiple atomizer cores 50 can be arranged sequentially and spaced apart along the first direction X, or arranged side by side, without limitation.

[0089] Optional, such as Figure 2 As shown, the atomizer core 50 encloses an atomizer chamber 51, which is connected to the oil inlet 241. The atomizer chamber 51 is used to receive the liquid to be atomized flowing down from the oil inlet 241. The atomized gas enters the mouthpiece 10 through the air flow channel 25 for easy inhalation by the user.

[0090] Optionally, a sealing ring 52 is provided on the outer surface of the atomizer core 50 , and the atomizer core 50 and the sealing ring 52 jointly seal the oil inlet 241 to prevent the atomized liquid flowing out of the oil inlet 241 from leaking from the outer surface of the atomizer core 50 to the air flow channel 25 .

[0091] The air flow channel 25 is spaced apart from the oil storage chamber 211 . The gas-liquid mixture formed by the atomizing core 50 atomizing the liquid to be atomized flows from the atomizing core 50 to the mouthpiece 10 through the air flow channel 25 for inhalation by the user.

[0092] By providing the atomizing portion 24 , the atomizing core 50 is accommodated in the atomizing portion 24 and the oil inlet 241 is sealed, so as to prevent the atomized liquid from leaking from the oil inlet 241 to the air flow channel 25 , thereby achieving a good atomization effect and a better user experience.

[0093] Optionally, the electronic atomizer 100 may further include a battery assembly (not shown), a base (not shown), etc., and any feasible structure may be adopted, and the embodiment of the present utility model does not impose any specific limitation.
