Description

[0001] The invention belongs to the technical field of electronic atomization, and in particular relates to an atomizer. Background Art

[0002] The atomizer includes a liquid storage tank, which stores atomized liquid for heating and atomizing to form an aerosol. However, if the sealing structure of the atomizer is not set properly, the air intake method is unreasonable, or it is improperly stored for a long time, it will cause liquid leakage. Since the air inlet of the atomizer is connected to the outside world and the battery rod, the leaked atomized liquid often flows into the outer casing or the inside of the battery rod through the air inlet, which can easily cause safety problems such as circuit damage and circuit self-starting. In addition, since most atomizers are shipped in a pre-filled manner, during long-distance transportation, due to the influence of external factors such as temperature and vibration, it is easy to cause leakage in the middle, so that users can clearly see the leakage after getting the atomizer, which creates a bad experience for users.

[0014] Furthermore, a stopper is provided between two adjacent layers of the partition plates, and the stopper defines a liquid passage for the liquid to flow in the circumferential direction in the interval between the two adjacent layers of the partition plates.

[0015] Furthermore, the liquid flow volume of the liquid flow channel in a direction away from the atomizing assembly is greater than the liquid flow volume of the liquid flow channel in a direction close to the atomizing assembly.

[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] See also Figure 1-6The present invention provides an atomizer, comprising: an oil cup 4, a flow retarder 5 arranged in the oil cup 4, and an atomizer assembly 6 connected to at least one of the oil cup 4 and the flow retarder 5; the oil cup 4 has a liquid storage chamber 41, the flow retarder 5 comprises a slow flow structure 51 arranged in the liquid storage chamber 41, and a ventilation structure 52 connected to one end of the slow flow structure 51; wherein the slow flow structure 51 is provided with a slow flow channel connected to the liquid storage chamber 41, and the ventilation structure 52 is provided with a ventilation channel connected to the liquid storage chamber 41 and the external atmosphere; the atomizer assembly 6 is connected to the downstream of the slow flow channel.

[0039] The present invention is provided with a flow retarder 5, which includes a ventilation structure 52 and a flow retarder structure 51, wherein the flow retarder structure 51 is located in the liquid storage chamber 41, and the flow retarder structure 51 is provided with a flow retarder channel connected to the liquid storage chamber 41, and the atomizer also includes an atomizing assembly 6 connected to the oil cup 4 or the flow retarder 5, and the atomizing assembly 6 is connected to the downstream of the flow retarder channel. Therefore, the atomized liquid in the liquid storage chamber 41 will be blocked by the flow retarder structure 51 during the flow process, and the atomized liquid in the liquid storage chamber 41 will flow to the atomizing assembly 6 through the flow retarder channel of the flow retarder structure 51. The flow retarder structure 51 will reduce the flow velocity of the atomized liquid in the flow retarder channel. The flow retarder structure 51 can buffer the flow of the atomized liquid, thereby ensuring the uniformity of the flow of the atomized liquid, and further ensuring the uniformity of the atomized liquid flowing to the atomizing assembly 6. When the atomizer is subjected to external force, the slow-flow structure 51 slows down the flow of the atomized liquid, thereby effectively preventing the atomizing assembly 6 from absorbing excessive atomized liquid under impact and causing leakage. At the same time, when inverted, the slow-flow structure 51 can also prevent the atomized liquid from flowing back quickly, avoiding the problem of dry burning caused by the atomized liquid flowing back too quickly when inhaling within a short time (such as 2 to 3 seconds) after inversion.

[0040] Furthermore, the flow slower 5 includes a main body 53 extending axially in the oil cup 4, an air flow channel 8 is provided in the main body 53, a slow flow structure 51 and a ventilation structure 52 are arranged on the outside of the main body 53 and are arranged at intervals along the axial direction to form a confluence space 54 connecting the slow flow channel and the ventilation channel; a through hole 531 connecting the confluence space 54 and the air flow channel 8 is also opened on the side wall of the main body 53; the atomization assembly 6 is at least partially arranged in the air flow channel 8, and is connected to the confluence space 54 through the through hole 531.

[0041] Specifically, in this embodiment, the main body 53 is a cylindrical structure, the slow flow structure 51 and the ventilation structure 52 are arranged outside the main body 53, and the two are arranged at intervals to form a confluence space 54, and the atomized liquid flowing down from the slow flow channel will flow in the confluence space 54. An airflow channel 8 is arranged in the main body 53, and a through hole 531 connecting the airflow channel 8 and the confluence space 54 is opened on the side wall of the main body 53. At least part of the atomizer assembly 6 is arranged in the airflow channel 8, so that the atomized liquid in the confluence space 54 can flow to the atomizer assembly 6 assembled in the airflow channel 8 through the through hole 531 to supply the atomizer assembly 6, and then an aerosol can be formed in the airflow channel 8. At least a portion of the ventilation channel is opened on the side wall of the main body 53 and is connected to the confluence space 54, so that the ventilation channel can balance the air pressure in the confluence space 54, and further balance the air pressure in the liquid storage chamber 41, thereby preventing the liquid storage chamber 41 from being unable to supply atomized liquid to the oil guide body 62 of the atomization component 6 due to insufficient air pressure, and can effectively avoid the problem of the oil guide body 62 of the atomization component 6 being dry-burned and burnt.

[0042] It should be understood that the shape of the slow-flow structure 51 can be adaptively adjusted according to the shape of the liquid storage chamber 41 of the oil cup 4. For example, if the oil cup 4 is an elliptical columnar structure, the slow-flow structure 51 is an elliptical annular columnar structure. In other embodiments, the slow-flow device 5 may not be provided with a main body 53, the oil cup 4 includes a cylindrical conduit, the slow-flow structure 51 and the liquid storage chamber 41 may be arranged outside the conduit, and the airflow channel 8 is arranged inside the conduit, which can also achieve the slow-flow effect of the slow-flow structure 51 on the atomized liquid.

[0043] Further, in the present embodiment, the air flow channel 8 includes an air outlet channel and an atomizing chamber that are interconnected, and an assembly hole and an air guide hole that extend in the axial direction of the oil cup 4 are provided in the main body 53, the air outlet channel is formed in the air guide hole, and the atomizing chamber is formed in the assembly hole, at least part of the atomizing assembly 6 is assembled in the assembly hole, and the main body 53 is provided with a through hole 531 that is directly opposite to the atomizing assembly 6; the oil cup 4 also includes an air outlet channel 43 located in the air guide hole, and the atomizing assembly 6 has an atomizing chamber, and the atomizing chamber is connected to the air outlet channel 43. The atomizing assembly 6 includes an atomizing core bracket 61 that is at least partially assembled in the assembly hole, an atomizing core base 64 assembled at one end of the atomizing core bracket 61 away from the air outlet pipe, a base silicone fixed to the inner side of the oil cup 4 and connected to the atomizing core base 64, an oil guide body 62 assembled on the atomizing core bracket 61, and a heating body 63 that is arranged to fit the oil guide body 62.

[0044] Specifically, in the present embodiment, the atomizer core bracket 61 and the oil guide body 62 are mainly annular columnar structures, the outer side of the atomizer core bracket 61 abuts against the hole wall of the assembly hole, the top side of the atomizer core bracket 61 abuts against the side edge of the top side of the assembly hole, and the bottom side of the atomizer core bracket 61 abuts against the atomizer core base 64, so that the atomizer core bracket 61 can be stably connected in the assembly hole; the outer side of the oil guide body 62 abuts against the inner wall of the atomizer core bracket 61, and a protrusion is arranged on the outer side of the oil guide body 62, and a groove matching the protrusion is arranged at a corresponding position of the inner wall of the atomizer core bracket 61. The protrusion is snapped into the groove, so that the oil guide body 62 can be stably connected to the inner side of the atomizer core bracket 61; the heating element 63 is bent from a sheet structure into a columnar structure, and the heating element 63 is attached to the inner wall of the oil guide body 62, so that when the heating element 63 is heated, the atomized liquid on the oil guide body 62 can be heated and atomized to form an aerosol. Since the heating element 63 is a columnar structure and is attached to the annular oil guide body 62, compared with the heating element 63 and the oil guide body 62 in plane contact, under the same atomization cavity space, the contact area between the two is larger, and the aerosol is better formed.

[0045] In some embodiments, the flow slowdown device 5 may not be provided with the main body 53, the atomization core bracket 61 may be provided with a cylindrical structure, the flow slowdown structure 51 and the liquid storage chamber 41 may be provided on the outside of the structure, and the air outlet channel 43 may be provided on the inside of the structure, which can also realize the flow slowdown effect of the flow slowdown structure 51 on the atomized liquid.

[0046] In some embodiments, the flow damper 5 can be integrally formed with the oil cup 4 .

[0047] It should be understood that the atomizer of the present application includes a slow-flow structure 51 of a slow-flow device 5, which can achieve a slow-flow effect on the atomized liquid, and can solve the technical problem of leakage caused by excessive flow rate of the atomized liquid. The actual setting structure of the atomizer assembly 6 has no specific restrictions, for example, the atomizer core bracket 61 and the atomizer core base 64 can be set as one body, the atomizer core base 64 and the base silicone can be set as one body, and the specific setting shape of each structure is not limited, for example, the atomizer assembly 6 can adopt a flat structure, or other structures, etc., or the atomizer assembly 6 can only include an oil guide body 62 and a heating element 63, and then the oil guide body 62 and the heating element 63 are fixed by the slow-flow device 5 and / or the oil cup 4.

[0048] Furthermore, the slow-flow structure 51 includes a plurality of partitions 511 spaced apart in the axial direction of the main body 53 , the slow-flow channel includes a slow-flow gap formed between two adjacent partitions 511 , and the slow-flow channel also includes an oil lowering channel 512 opened on each partition 511 .

[0049] The slow-flow structure 51 includes a multi-layer partition 511. Therefore, when the atomized liquid in the liquid storage chamber 41 flows to the atomizing component 6, the multi-layer partition 511 will reduce the flow space of the atomized liquid, and the partition 511 will hinder the flow of the atomized liquid. The atomized liquid flows to the atomizing component 6 through the slow-flow channel of the slow-flow structure 51, thereby buffering the flow of the atomized liquid and ensuring the uniformity of the flow of the atomized liquid, thereby ensuring the uniformity of the atomized liquid flowing to the atomizing component 6; when the atomizer is subjected to external force, the partition 511 can also play a slow-flow role to prevent the atomizing component 6 from absorbing excessive liquid under the action of external force and causing leakage. The slow flow channel includes a slow flow gap formed between two adjacent partitions 511 and a lower oil channel 512 arranged on each partition 511. Therefore, when the atomized liquid flows toward the atomization assembly 6, the atomized liquid will flow between the two adjacent partitions 511, and then flow downward from the lower oil channel 512 of the partition 511, and continue to flow between the slow flow gaps of the two partitions 511, and finally the atomized liquid will flow toward the atomization assembly 6.

[0050] Furthermore, among the multiple partitions 511, the spacing between adjacent partitions 511 in the slow-flow structure 51 away from the atomization assembly 6 is greater than the spacing between adjacent partitions 511 in the direction close to the atomization assembly 6. Therefore, when the atomized liquid flows in the slow-flow structure 51, in the process of flowing to the partition 511 close to the atomization assembly 6, the flow rate of the atomized liquid will be further slowed down due to the reduction in the spacing between adjacent partitions 511, that is, when approaching the atomization assembly 6, the flow rate of the atomized liquid will be further reduced, thereby effectively preventing the atomized liquid from flowing too fast, resulting in excessive atomized liquid content in the atomization assembly 6 and leakage.

[0051] In some specific embodiments, the flow-slowing structure 51 is divided into at least an upstream zone and a downstream zone in the axial direction. The extension length L1 of the upstream zone along the axial direction and the extension length L2 of the downstream zone along the axial direction may be the same or different. Specifically, L1:L2 may be 1:1, 1:2, 2:1:, 3:1, etc., wherein the spacing between two adjacent layers of partitions 511 in the upstream zone is greater than the spacing in the downstream zone.

[0052] In some other specific embodiments, the distance between two adjacent layers of partition plates 511 may also gradually decrease from the upstream area to the downstream area.

[0053] Furthermore, the lower oil channels 512 of two adjacent partitions 511 are staggered in the circumferential direction.

[0054] In this embodiment, inside the oil cup 4, the peripheral side of the slow flow structure 51 abuts against the cavity wall of the liquid storage cavity 41, that is, the peripheral side of each layer of the partition 511 abuts against the cavity wall of the liquid storage cavity 41, and the atomized liquid flows to the atomizing assembly 6 through the slow flow channel. The slow flow channel includes a lower oil channel 512. In this embodiment, the lower oil channel 512 can be set as a lower oil groove parallel to the axial direction of the slow flow device 5, and the transverse cross-sectional shape of the lower oil groove can be V-shaped, U-shaped, etc.

[0055] Furthermore, two adjacent lower oil grooves can be arranged in a circumferentially staggered manner, so as to increase the flow path of the atomized liquid between the two layers of partitions 511. For example, between five adjacent partitions 511, since the lower oil grooves are arranged in a circumferentially staggered manner, the atomized liquid needs to flow in the circumferential direction when it flows from the slow-flow gap at the top to the slow-flow gap in the middle and then to the slow-flow gap at the bottom. In this way, the flow path of the atomized liquid will be lengthened, which can further reduce the flow rate of the atomized liquid and improve the leakage prevention effect.

[0056] In some other embodiments, the lower oil channels 512 can be arranged in alignment. In this case, the oil lowering path can be extended by setting the extension direction of the lower oil channel 512 to have an angle relationship with the axial direction of the oil cup 4, or setting the lower oil channel 512 to bend and extend, etc., thereby achieving the effect of reducing the lower oil flow rate.

[0057] Furthermore, the liquid flow volume of the lower oil channel 512 in the direction away from the atomizing assembly 6 is greater than the liquid flow volume of the lower oil channel 512 in the direction close to the atomizing assembly 6 .

[0058] Specifically, in the present embodiment, the lower oil channel 512 is a lower oil trough, and the size of the liquid flow volume depends on the height of the lower oil trough. The extension height of the lower oil trough is equal to the thickness of the partition 511, and the partitions 511 of each layer in the present embodiment are of the same height. Therefore, in the present embodiment, the transverse cross-sectional area of ​​the lower oil trough in the direction away from the atomization component 6 is larger than the transverse cross-sectional area of ​​the lower oil trough in the direction close to the atomization component 6, so that the oil-falling speed of the atomized liquid between the partitions 511 away from the atomization component 6 is greater than the oil-falling speed between the partitions 511 close to the atomization component 6, thereby ensuring that the flow rate of the atomized liquid is slower when flowing to the oil guide body 62, further playing a slow flow effect.

[0059] In other embodiments, the thickness of each layer of partition 511 is not equal, wherein the thickness of the partition 511 away from the atomization assembly 6 is greater than the thickness of the partition 511 close to the atomization assembly 6. At this time, the transverse cross-sectional area of ​​the lower oil tank away from the atomization assembly 6 can be greater than or equal to the transverse cross-sectional area of ​​the lower oil tank close to the atomization assembly 6. Even when the height difference of each layer of partition 511 is more obvious, the transverse cross-sectional area of ​​the lower oil tank away from the atomization assembly 6 can be smaller than the transverse cross-sectional area of ​​the lower oil tank close to the atomization assembly 6. At this time, it is only necessary to ensure that the liquid flow volume of the lower oil channel 512 away from the atomization assembly 6 is greater than the liquid flow volume of the lower oil channel 512 close to the atomization assembly 6, so as to achieve the same slow flow effect.

[0060] In some embodiments, the lower oil channel 512 may be a lower oil through hole 531 opened on the partition 511, and the transverse cross-sectional shape of the lower oil channel 512 may be square, circular, elliptical, triangular, rectangular, etc. The configuration of the lower oil through hole 531 is similar to that of the lower oil tank, and will not be described in detail here.

[0061] Furthermore, a stopper 513 is provided between two adjacent layers of the partition plates 511 , and the stopper 513 defines a liquid passage 514 for the liquid to flow in the circumferential direction in the interval between the two adjacent layers of the partition plates 511 .

[0062] Specifically, the stopper 513 can be a protrusion protruding from the upper surface of the partition 511, or can be a protrusion protruding from the lower surface of the partition 511, or can be a protrusion connected to the two layers of partitions 511; in addition, the stopper 513 can extend radially of the flow damper 5, and / or can extend circumferentially of the flow damper 5.

[0063] Among them, the extended length of the block 513 along the radial extension of the flow damper 5 is less than or equal to the radial length of the partition 511. When the extended length of the block 513 along the radial extension of the flow damper 5 is equal to the radial length of the partition 511, a plurality of liquid holes are opened on the block 513, and the shape of the liquid holes can be circular, triangular, rectangular, square, elliptical, etc.

[0064] The liquid passage 514 can be a space formed by the outer surface of the block 513 (including the liquid passage hole when there is one), the upper and lower partitions 511, and the inner side of the oil cup 4. During the oiling process, the atomized liquid flows in the liquid passage 514 between two adjacent layers of partitions 511. For example, when the block 513 is a protrusion connected to the two layers of partitions 511, the liquid passage 514 can be a space defined by the side wall of the block 513 in the radial direction and the outer wall of the main body 53 (in this case, the block 513 is arranged at the edge of the partition 511); or, the liquid passage 514 can be a space formed by the side wall of the block 513 in the radial direction and the inner wall of the oil cup 4 (in this case, the block 513 can be the outer wall protruding from the main body 53); or, the liquid passage 514 can be a space defined by the side wall of the block 513 in the radial direction and the outer wall of the main body 53, and a space formed by the side wall of the block 513 in the radial direction and the inner wall of the oil cup 4 (in this case, the block 513 is arranged in the middle position of the partition 511). When the stopper 513 is a protrusion protruding from the upper surface of the partition 511, or a protrusion protruding from the lower surface of the partition 511, in the axial direction, the liquid passage 514 also includes a space formed by the top or bottom of the stopper 513 and the partition 511, that is, the stopper 513 and the partition 511 jointly define the liquid passage 514. By setting the stopper 513, the oil-falling space of the atomized liquid will be reduced, and the stopper 513 will also block the atomized liquid, thereby further reducing the oil-falling speed of the atomized liquid, and also playing a slow flow role.

[0065] Furthermore, the liquid flow volume of the liquid flow channel 514 in the direction away from the atomization assembly 6 is greater than the liquid flow volume of the liquid flow channel 514 in the direction close to the atomization assembly 6 .

[0066] Specifically, the liquid flow volume of the liquid flow channel 514 can be changed by changing the extension length of the stopper 513 extending axially and / or radially along the main body 53 . For the same flow slower 5, in the direction from the slow flow structure 51 away from the atomizing assembly 6 to the slow flow structure 51 close to the atomizing assembly 6, the extension length of the block 513 between the partitions 511 away from the atomizing assembly 6 along the radial direction of the oil cup 4 can be set to be smaller than the extension length of the block 513 between the partitions 511 close to the atomizing assembly 6 along the radial direction of the oil cup 4, so that the liquid flow volume of the liquid passage 514 away from the atomizing assembly 6 is larger than the liquid flow volume of the liquid passage 514 close to the atomizing assembly 6. Therefore, the atomized liquid has a faster flow speed in the oil filling area (the direction away from the atomizing assembly 6 and the direction close to the atomizing assembly 6), thereby accelerating the oil filling efficiency, and in the oil inlet area (close to the atomizing assembly 6, the atomized liquid flows from the liquid storage chamber 41 through the atomizing assembly 6 to the oil guide body 62), the flow speed is slowed down, thereby playing a slow flow role, which can effectively prevent excessive atomized liquid from flowing into the oil guide body 62 due to excessive flow speed, which ultimately leads to leakage.

[0067] Furthermore, the surface of the partition plate 511 along the axial direction of the main body 53 facing away from the ventilation structure 52 is a rough surface.

[0068] The atomized liquid will flow in the slow flow channel, and the slow flow channel includes a slow flow gap and an oil lower channel 512, wherein the slow flow gap is formed between two adjacent partitions 511. Since the surface of each layer of partition 511 that is away from the ventilation structure 52 is a rough surface, that is, the side of the slow flow structure 51 that is in contact with the atomized liquid can adopt a frosted effect or a structure such as a protrusion or a groove, the rough surface can be used to slow the flow of the atomized liquid in the oil storage tank and reduce the fluidity of the atomized liquid, thereby effectively preventing the atomized liquid from flowing too fast and leaking due to excessive atomized liquid in the oil guide body 62.

[0069] Furthermore, the roughness of the rough surface ranges from Ra3.2 to 12.5. Specifically, the roughness can be 3.2, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, 10.5, 11, 11.5, 12, 12.5, etc., preferably Ra is 8, so as to reduce the manufacturing difficulty and slow down the flow of the atomized liquid to the maximum extent.

[0070] Furthermore, the ventilation structure 52 includes a bottom cover 525 connected to one end of the main body 53 away from the slow-flow structure 51 and a plurality of bottom plates 521 arranged at intervals between the bottom cover 525 and the slow-flow structure 51. The ventilation channel includes a ventilation gap 523 formed between adjacent bottom plates 521. The ventilation channel also includes a ventilation groove 522 opened on each bottom plate 521. The bottom cover 525 covers the bottom opening of the liquid storage chamber 41.

[0071] Specifically, in this embodiment, the flow retarder 5 includes a ventilation structure 52 connected to one end of the flow retarding structure 51, and the ventilation structure 52 includes a columnar bottom cover 525 arranged outside the main body 53 and the outermost side of which abuts against the inner side of the oil cup 4, and a plurality of bottom plates 521 arranged at intervals between the bottom cover 525 and the flow retarding structure 51. By providing the bottom cover 525, the bottom cover 525 covers the opening of the liquid storage cavity 41, so that the bottom cover 525 can play a certain sealing role on the liquid storage cavity 41, so that the liquid storage cavity 41 has a liquid storage function, and prevents the atomized liquid in the liquid storage cavity 41 from leaking to the outside.

[0072] Among them, the ventilation channel includes a ventilation gap 523 formed between two adjacent bottom plates 521 and a ventilation groove 522 provided on each bottom plate 521, so that the ventilation airflow can circulate between the ventilation groove 522 and the ventilation gap 523, and the ventilation airflow flows from the outside to the liquid storage chamber 41 to balance the air pressure in the liquid storage chamber 41. The ventilation gap 523 can also be used as an oil storage tank to store the atomized liquid that may leak during the ventilation process (although the flow retarder 5 can effectively prevent leakage, it is inevitable that leakage will occur during actual use) to prevent the atomized liquid from flowing downward. The transverse cross-sectional shape of the ventilation groove 522 can be U-shaped, V-shaped or S-shaped, etc., so that the ventilation airflow flows inside the ventilation groove 522 and the oil cup 4, and the liquid storage chamber 41 can be ventilated through the micro ventilation groove 522 (in actual process, the airflow flows through the ventilation groove 522 and the ventilation gap 523, and then flows to the liquid storage chamber 41), to prevent insufficient supply of atomized liquid.

[0073] In other embodiments, the extension direction of the ventilation groove 522 may not be parallel to the axial direction of the oil cup 4. In other embodiments, the ventilation structure 52 may be a ventilation guide hole provided on the main body 53 of the flow damper 5, and the ventilation guide hole penetrates into the atomization chamber, which can also realize ventilation.

[0074] In some other embodiments, the flow damper 5 may not include the bottom cover 525. In this case, the last layer of partition 511 of the flow damper structure 51 can be used as a cover body to cover the liquid storage chamber 41, and the ventilation structure 52 can be set on the partition 511, that is, the last layer of partition 511 can be provided with micro ventilation holes 531 or micro ventilation grooves 522 extending along the central axis of the oil cup 4. In this case, the liquid storage chamber 41 can be ventilated directly through the ventilation channel on the last layer of partition 511 to balance the air pressure in the liquid storage chamber 41, thereby simplifying the structure of the flow damper 5 and reducing the manufacturing and assembly processes.

[0075] Furthermore, the atomizer also includes a battery rod assembly 7, which is connected to the end of the oil cup 4 away from the suction nozzle 1. By setting the ventilation gap 523 as an oil storage tank, the atomized liquid can be prevented from flowing into the battery rod assembly 7, thereby preventing the battery rod assembly 7 from self-starting, circuit board damage and other problems, thereby improving safety and ensuring the service life of the battery rod assembly 7.

[0076] Furthermore, the ventilation grooves 522 of adjacent floors are staggered in the circumferential direction. Specifically, in this embodiment, a layer of the bottom plate 521 is correspondingly provided with a ventilation groove 522, and the ventilation grooves 522 are staggered. Therefore, during the ventilation process, if the atomized liquid leaks from the liquid storage chamber 41 through the top ventilation groove 522, the leaked liquid does not flow axially from one ventilation groove 522 to the next ventilation groove 522, but needs to flow circumferentially and will flow to the ventilation gap 523, so that the leaked liquid can be stored in the ventilation gap 523, thereby improving the anti-leakage effect. In other embodiments, a plurality of ventilation grooves 522 are correspondingly provided on a layer of the bottom plate 521, and the plurality of ventilation grooves 522 are arranged at staggered intervals. By providing a plurality of ventilation grooves 522, a plurality of ventilation channels are provided. When one of the ventilation channels is blocked by liquid leakage, ventilation can be performed through other ventilation channels to ensure the ventilation process of the liquid storage chamber 41 and prevent the oil guide body 62 from being dry-burned and burnt.

[0077] Furthermore, at least one bottom plate 521 is provided with a flange structure 524 on its outer surface, and the flange structure 524 abuts against the inner wall of the oil cup 4. In this embodiment, the outer surfaces of several bottom plates 521 are provided with flange structures 524. The flange structure 524 is a circular structure, which surrounds the outer surface of the bottom plate 521. The flange structure 524 and the inner wall of the oil cup 4 are interference fit. When the atomized liquid leaks from the liquid storage chamber 41, the flange structure 524 can block the leaking liquid, so that the leaking liquid cannot leak from the outer side of the bottom cover 525 and the inner side of the oil cup 4, which can effectively prevent the leakage of liquid and has a self-sealing effect. In other embodiments, only the bottom plate 521 of the top layer in the cover plate may be provided with a flange structure 524, or the bottom plates 521 of other layers may be provided with a flange structure 524, or the bottom plates 521 of the top layer and the middle layer may be provided with a flange structure 524, and so on.

[0078] Furthermore, an oil filling hole 42 is provided at one end of the oil cup 4 away from the atomizing assembly 6 , and the end of the flow retarder 5 away from the atomizing assembly 6 is spaced apart from the end wall of the oil cup 4 having the oil filling hole 42 to form an oil filling space connected to the oil filling hole 42 .

[0079] In this embodiment, the atomizer also includes a suction nozzle 1, filter cotton 2 and a sealing silicone sleeve 3. The suction nozzle 1 is assembled on the end of the oil cup 4 away from the atomization assembly 6, and the sealing silicone sleeve 3 covers the sealing oil filling hole 42; the filter cotton 2 is clamped between the suction nozzle 1 and the sealing silicone sleeve 3, so that when the aerosol formed in the atomization chamber flows out from the air outlet channel 43, it can pass through the filter cotton 2 and then flow to the suction nozzle 1, which can filter the aerosol, ensure the quality of the aerosol, and improve the user experience.

[0080] Specifically, the oil filling space is the space from the outside of the main body 53 to the inner wall of the oil cup 4, and a relatively spacious oil filling space is arranged above the slow flow structure 51, so that when the atomized liquid is added into the liquid storage chamber 41 through the oil filling hole 42, the oil filling speed can be increased, and when the atomized liquid flows toward the slow flow structure 51, the slow flow structure 51 can buffer the atomized liquid, reduce the flow rate of the atomized liquid, so that the atomized liquid can flow evenly to the atomizing component 6, thereby effectively preventing leakage.

[0081] Among them, the oil injection space can be the spacing space from the flow slowdown device 5 to the oil injection hole 42 along the axial direction, that is, a cavity formed by a certain gap distance between the top end face of the flow slowdown structure 51 and the bottom end face of the oil injection hole 42, that is, at this time the main body 53 does not extend to the oil injection space.

[0082] Furthermore, the damper 5 can be integrally molded using a material with a relatively low hardness, such as silicone, so that when the damper 5 is disposed in the oil cup 4, the damper 5 and the inner wall of the oil cup 4 have a good interference fit effect. In other embodiments, a fixing structure such as a buckle structure can be provided between the damper 5 and the oil cup 4 so that the two can be stably connected by the buckle while abutting against each other.

[0083] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0084] The above is a description of the technical solution provided by the present invention. For those skilled in the art, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
