The atomizing core 3 is arranged in the shell 1 and is respectively communicated with the oil storage bin 11 and the atomizing bin 13, and the atomizing core 3 is used for atomizing the medium to be atomized in the oil storage bin 11.
For example, in the example of fig. 1 to 3, the air passage 12 and the oil reservoir 11 may be arranged in the width direction (e.g., left-right direction in fig. 1) of the housing 1, and the oil reservoir 11 is for containing a liquid medium to be atomized, such as tobacco tar. The oil reservoir 11 and the atomizing reservoir 13 may be arranged along the length direction (e.g., up-down direction in fig. 1) of the housing 1, with the atomizing core 3 being located between the oil reservoir 11 and the atomizing reservoir 13.

Wherein the ratio of the absolute value of the difference in cross-sectional areas of at least two of the atomizing hopper outlet 2, the air passage 12, the air suction passage 145, and the air suction port 141 to the cross-sectional area of any one of the atomizing hopper outlet 2, the air passage 12, the air suction passage 145, and the air suction port 141 is 20% or less. In another embodiment of the present application, the ratio of the absolute value of the difference in cross-sectional areas of any two of the atomizing cartridge outlet 2, the air passage 12, the air suction passage 145, and the air suction port 141 to the cross-sectional area of any one of the atomizing cartridge outlet 2, the air passage 12, the air suction passage 145, and the air suction port 141 is less than or equal to 20%; that is, the difference in cross-sectional area between any two of the atomizing hopper outlet 2, the air passage 12, the air suction passage 145 and the air suction port 141 satisfies the ratio to the cross-sectional area of any one of the atomizing hopper outlet 2, the air passage 12, the air suction passage 145 and the air suction port 141 by 20% or less.
For example, the ratio of the absolute value of the difference in cross-sectional area of any two of the atomizing cartridge outlet 2, the air passage 12, the suction passage 145, and the suction port 141 to the cross-sectional area of the atomizing cartridge outlet 2 is 20% or less; alternatively, the ratio of the absolute value of the difference in cross-sectional areas of any two of the atomizing cartridge outlet 2, the air passage 12, the suction passage 145, and the suction port 141 to the cross-sectional area of the air passage 12 is less than or equal to 20%; still alternatively, the ratio of the absolute value of the difference in cross-sectional areas of any two of the atomizing cartridge outlet 2, the air passage 12, the suction passage 145, and the suction port 141 to the cross-sectional area of the suction passage 145 is less than or equal to 20%; still alternatively, the ratio of the absolute value of the difference in cross-sectional areas of any two of the atomizing cartridge outlet 2, the air passage 12, the suction passage 145, and the suction port 141 to the cross-sectional area of the suction port 141 is 20% or less. Thus, the cross-sectional area design of the atomizing bin outlet 2, the air passage 12, the air suction passage 145 and the air suction port 141 can be reasonable.
For example, when the ratio of the absolute value of the difference between the cross-sectional area of the air passage 12 and the cross-sectional area of the air suction port 141 to the cross-sectional area of the air passage 12 is 20% or less, it is indicated that the difference between the cross-sectional area of the air passage 12 and the cross-sectional area of the air suction port 141 is not large, and the atomized medium can smoothly flow in the air passage 12. Therefore, when the atomizing device 100 works, the air in the atomizing bin 13 and the smoke formed by atomization can be guaranteed to be fully mixed and smoothly flow to the air passage 12 and then to the air suction port 141, the resistance of a user during suction can be reduced, and meanwhile, the mixed air flow can be prevented from forming condensate in the air passage 12, so that the user can be prevented from sucking liquid tobacco tar during suction, and the user experience is improved.
The following exemplifies the operation of the atomizer 100 when it is applied to an electronic cigarette.
After the atomization device 100 is combined with the tobacco rod, a user inhales through the air suction port 141, at the moment, a pneumatic sensor (such as a microphone) in the tobacco rod senses, so that a power supply in the tobacco rod is electrically connected with the atomization core 3, the atomization core 3 works, such as the atomization core 3 is heated, a medium to be atomized in the oil storage bin 11, such as tobacco tar, moves towards the atomization bin 13 and is heated by the atomization core 3, smoke (including but not limited to aerosol, suspension liquid, low-temperature vapor and volatile gas) is formed in the atomization bin 13, and meanwhile, external air enters the atomization bin 13 through the air inlet 71 and is mixed with the smoke in the atomization bin 13, and the mixed smoke is inhaled by the user from the air suction port 141 through the atomization bin outlet 2, the air channel 12 and the air suction channel 145, so that the use requirement of the user is met. When the user stops inhaling from the air suction port 141, the medium to be atomized, such as tobacco tar, in the oil storage bin 11 can stop entering the atomization bin 13 from the atomization core 3, so that ineffective consumption of the medium to be atomized in the oil storage bin 11 is avoided, and the utilization rate of the medium to be atomized is improved. Here, it should be explained that some electronic cigarettes provide the atomizing device 100 and the stem in separate structures, and the two are detachably combined, and some electronic cigarettes provide the atomizing device 100 and the stem in a non-detachable structure, which is not particularly limited herein.
According to the atomization device 100 for the electronic cigarette, provided by the embodiment of the invention, the difference of the cross sectional areas of at least two of the atomization bin outlet 2, the air channel 12, the air suction channel 145 and the air suction port 141 is smaller than or equal to 20%, so that the mixed air flow in the atomization bin 13 can be ensured to smoothly flow to the air channel 12, the resistance of a user during suction can be reduced, condensate formed in the air channel 12 by the mixed air flow is avoided, and the user experience is improved.
According to some embodiments of the invention, the ratio of the absolute value of the difference in cross-sectional areas of any two of the nebulization cartridge outlet 2, the air channel 12, the suction channel 145 and the suction port 141 to the cross-sectional area of any one of the air channel 12 and the suction port 141 is less than or equal to 20%. Wherein the first one can be that the ratio of the absolute value of the difference between the cross sectional areas of the atomizing bin outlet 2 and the air passage 12 to the cross sectional area of any one of the air passage 12 and the air suction port 141 is 20% or less; the second may be that the ratio of the absolute value of the difference in cross-sectional areas of the atomizing hopper outlet 2 and the suction passage 145 to the cross-sectional area of either one of the air passage 12 and the suction port 141 is 20% or less; the third type may be that the ratio of the absolute value of the difference in cross-sectional areas of the atomizing hopper outlet 2 and the air suction port 141 to the cross-sectional area of any one of the air passage 12 and the air suction port 141 is 20% or less; the fourth may be that the ratio of the absolute value of the difference in cross-sectional areas of the air passage 12 and the suction passage 145 to the cross-sectional area of any one of the air passage 12 and the suction port 141 is 20% or less; the fifth may be a ratio of an absolute value of a difference in cross-sectional areas of the air passage 12 and the suction port 141 to a cross-sectional area of any one of the air passage 12 and the suction port 141 is 20% or less; the sixth may be that the ratio of the absolute value of the difference in cross-sectional areas of the suction passage 145 and the suction port 141 to the cross-sectional area of any one of the air passage 12 and the suction port 141 is 20% or less. Thus, the mixed gas flow in the atomizing bin 13 can smoothly flow to the oral cavity of the user through the air passage 12 and the air suction passage 145, and the resistance of the user during suction is reduced.
According to some embodiments of the invention, the cross-sectional area of the nebulization cartridge outlet 2 is S 1 The cross-sectional area of the air passage 12 is S 2 The cross-sectional area of the suction channel 145 is S 3 The cross-sectional area of the suction port 141 is S 4 Wherein S is 1 、S 2 、S 3 、S 4 The following respectively satisfy: 3mm 2 ≤S 1 ≤6mm 2 ，3mm 2 ≤S 2 ≤6mm 2 ，3mm 2 ≤S 3 ≤6mm 2 ，3mm 2 ≤S 4 ≤6mm 2 . When S is 1 ＜3mm 2 When in use, the cross-sectional area of the outlet 2 of the atomization bin is smaller, and the mixed air flow in the atomization bin 13 is not easy to flowTo airway 12, resistance to user suction may be increased, affecting user experience; when S is 1 ＞6mm 2 When in use, the cross-sectional area of the atomizing bin outlet 2 is larger, so that atomized medium in the atomizing bin 13 cannot be fully mixed with air and flows to the air channel 12, and the user experience is also influenced. When S is 2 ＜3mm 2 When the cross-sectional area of the air passage 12 is smaller, the air passage 12 is narrower, so that the smoke amount sucked by a user during suction is smaller; when S is 2 ＞6mm 2 The larger cross-sectional area of airway 12 increases resistance to user aspiration.
When S is 3 ＜3mm 2 When the cross-sectional area of the air suction channel 145 is smaller, the mixed air flow of the air channel 12 is not easy to flow to the air suction channel 145, so that the resistance of the user during suction can be increased, and the user experience is affected; when S is 3 ＞6mm 2 The cross-sectional area of the inhalation passage 145 is large, so that a user may inhale a large amount of smoke while inhaling, and the user's experience may be affected as well. When S is 4 ＜3mm 2 The cross-sectional area of the suction port 141 is small, so that the amount of smoke sucked by the user is small when sucking, and in addition, when the user sucks with great force, the user may be choked by the smoke; when S is 4 ＞6mm 2 In this case, the cross-sectional area of the suction port 141 is large, and thus the resistance to the suction of the user is increased.
The cross-sectional areas of the atomizing chamber outlet 2, the air passage 12, the air suction passage 145 and the air suction port 141 may be equal, and the mixed air flow in the atomizing chamber 13 may smoothly flow to the oral cavity of the user when the user sucks.
Thus, by making S 1 、S 2 、S 3 、S 4 The following respectively satisfy: 3mm 2 ≤S 1 ≤6mm 2 ，3mm 2 ≤S 2 ≤6mm 2 ，3mm 2 ≤S 3 ≤6mm 2 ，3mm 2 ≤S 4 ≤6mm 2 The cross-sectional areas of the atomizing bin outlet 2, the air passage 12, the air suction channel 145 and the air suction port 141 can be designed reasonably, the resistance of the atomizing bin 13 during the suction of a user can be reduced while the atomized medium can be fully mixed with the airThe mixed air flow can flow to the oral cavity of the user through the air suction port 141 rapidly and smoothly, and the user can inhale a proper amount of smoke when inhaling, thereby improving the user experience
According to some embodiments of the present invention, the housing 1 has a length direction (e.g., up-down direction in fig. 1), a width direction (e.g., left-right direction in fig. 1), and a thickness direction (e.g., left-right direction in fig. 2), wherein a maximum dimension in the length direction is greater than a maximum dimension of the housing 1 in the width direction and the thickness direction, and the air duct 12 is offset from a central axis of the air suction port 141 in the width direction, i.e., a central axis of the air duct 12 is offset from a central axis of the air suction port 141 in the width direction. Referring to fig. 1, a central axis of the suction port 141 substantially coincides with a central axis of the casing 1 along a length direction of the casing 1. In other words, the suction port 141 is located at the middle of one end of the casing 1. The central axis of the air duct 12 may be located to the left or right of the central axis of the housing 1. Therefore, when a user inhales through the air suction port 141, the smoke in the atomization bin 13 can flow to the middle part of the oral cavity of the user more smoothly after passing through the air passage 12 and the air suction channel 145, and the smoke can be uniformly distributed in the oral cavity of the user, so that the user experience is further improved.
According to a further embodiment of the present invention, referring to fig. 1 and 3, the atomizing device 100 for an electronic cigarette further includes an atomizing core fixing structure 4 and an elastic sealing member 5, an atomizing core installation cavity 41 and a ventilation cavity 42 are formed on the atomizing core fixing structure 4 to be spaced apart from each other, the ventilation cavity 42 communicates with the atomizing chamber 13, and the atomizing core 3 is provided in the atomizing core installation cavity 41. The elastic sealing piece 5 is sleeved on the atomization core fixing structure 4, at least one part of the elastic sealing piece 5 is located between the inner wall surface of the shell 1 and the atomization core fixing structure 4, a ventilation channel 6 is defined between the elastic sealing piece 5 and the atomization core fixing structure 4, and the ventilation channel 6 is respectively communicated with the ventilation cavity 42 and the oil storage bin 11.
For example, in the example of fig. 1 and 3, the atomizing core mounting chamber 41 and the ventilation chamber 42 may be spaced apart from each other in the width direction of the housing 1, and the shape of the atomizing core mounting chamber 41 is adapted to the shape of the atomizing core 3 to firmly mount the atomizing core 3 on the atomizing core fixing structure 4. The atomizing core fixing structure 4 can be in sealing connection with the inner wall surface of the shell 1 through the elastic sealing piece 5, so that the medium to be atomized in the oil storage bin 11 can be prevented from flowing into the atomizing bin 13 from a gap between the atomizing core fixing structure 4 and the inner wall surface of the shell 1, and the waste of the medium to be atomized can be avoided.
When the atomization device 100 works, when the medium to be atomized in the oil storage bin 11 moves into the atomization bin 13 through the atomization core 3, the inside of the oil storage bin 11 is in a negative pressure state, at the moment, the pressure of the oil storage bin 11 is smaller than that of the atomization bin 13, gas in the atomization bin 13 flows to the ventilation cavity 42 and flows into the oil storage bin 11 through the ventilation channel 6, so that the pressure of the oil storage bin 11 and the pressure of the atomization bin 13 are kept balanced, and the medium to be atomized in the oil storage bin 11 can continuously move into the atomization bin 13 through the atomization core 3, so that the atomization core 3 can obtain enough medium to be atomized to keep the generation effect of smoke.
Further, referring to fig. 9 to 12, at least one ventilation hole 43 and at least one ventilation groove 44 are formed on the outer circumferential surface of the atomizing core fixing structure 4, the ventilation hole 43 penetrates through the outer circumferential wall of the atomizing core fixing structure 4 and is communicated with the inside of the ventilation cavity 42, one end of the ventilation groove 44 is connected with the ventilation hole 43, the other end of the ventilation groove 44 penetrates through the surface of the atomizing core fixing structure 4 facing the oil storage bin 11, and a ventilation channel 6 is defined among the ventilation hole 43, the ventilation groove 44 and the elastic sealing member 5. When the pressure of the atomization bin 13 is greater than the pressure of the oil storage bin 11, the air flow in the atomization bin 13 can flow to the ventilation cavity 42, the air flow in the ventilation cavity 42 can flow to the ventilation groove 44 through the ventilation hole 43, and the air flow flows to the other end at one end of the ventilation groove 44, so that the air flow in the atomization bin 13 flows to the oil storage bin 11, and the aim of adjusting the pressure difference between the oil storage bin 11 and the atomization bin 13 is fulfilled.
Further, the length of the ventilation groove 44 is longer than the distance between the ventilation hole 43 and the other end of the ventilation groove 44. As shown in fig. 9 to 12, the ventilation hole 43 is formed at one side of the atomizing core fixing structure 4 in the thickness direction of the housing 1, a part of the ventilation groove 44 extends to the other side of the atomizing core fixing structure 4 in the thickness direction of the housing 1, and the other end of the ventilation groove 44 is located at one end of the atomizing core fixing structure 4 in the width direction of the housing 1. The shape of the ventilation groove 44 is a zigzag shape, so that the length of the ventilation groove 44 is increased, and when the ventilation channel 6 is opened, a small amount of medium to be atomized can be stored in the ventilation groove 44, so that the medium to be atomized is prevented from directly flowing into the atomization bin 13, the medium to be atomized can be prevented from being inhaled by a user, and the user experience is ensured.
Further, the ventilation groove 44 includes a first ventilation groove section 441 and a second ventilation groove section 442, one end of the first ventilation groove section 441 is connected to the ventilation hole 43, and the other end of the first ventilation groove section 441 extends to the above-described other side of the atomizing core fixing structure 4 in the thickness direction of the outer shell 1.

Therefore, the length of the first ventilation groove section 441 is increased, and the first ventilation groove section 441 is simple in structure and convenient to process.
One end of the second ventilation groove section 442 is connected to the other end of the first ventilation groove section 441, and the other end of the second ventilation groove section 442 penetrates the one side surface of the atomizing core fixing structure 4 facing the oil reservoir 11. Referring to fig. 10, the second ventilation groove section 442 has a U-shape, and the second ventilation groove section 442 may include a third ventilation sub-section, a fourth ventilation sub-section, and a fifth ventilation sub-section, wherein the third ventilation sub-section extends along the thickness direction of the atomizing core fixing structure 4, and one end of the third ventilation sub-section is connected to the other end of the first ventilation groove section 441.

The fifth ventilation sub-section extends in the thickness direction of the atomizing core fixing structure 4, and one end of the fifth ventilation sub-section is connected to the other end of the fourth ventilation sub-section, and the other end of the fifth ventilation sub-section penetrates the other side surface in the thickness direction of the atomizing core fixing structure 4. Thereby, the length of the second ventilation groove section 442 is increased, so that the length of the ventilation groove 44 can be effectively increased, the length of the ventilation groove 44 is larger than the distance between the ventilation hole 43 and the other end of the ventilation groove 44, and meanwhile, the second ventilation groove section 442 is simple in structure and convenient to process.
According to other embodiments of the present invention, as shown in fig. 13, the ventilation hole 43 is formed at one end of the atomizing core fixing structure 4 in the width direction of the housing 1, and the other end of the ventilation groove 44 is located at one side of the atomizing core fixing structure 4 in the thickness direction of the housing 1. So set up, the length of ventilation groove 44 is shorter, and when the pressure of atomizing storehouse 13 is greater than the pressure of oil storage storehouse 11, the air current in the ventilation groove 44 can open ventilation channel 6 fast to can the pressure of quick adjustment oil storage storehouse 11 and atomizing storehouse 13.
Further, as shown in fig. 13, the ventilation groove 44 includes a third ventilation groove section 443 and a fourth ventilation groove section 444, the third ventilation groove section 443 extends in the circumferential direction of the atomizing core fixing structure 4, one end of the third ventilation groove section 443 is connected to the ventilation hole 43, and the other end of the third ventilation groove section 443 extends to one side in the thickness direction of the housing 1. One end of the fourth ventilation slot section 444 is connected to the other end of the third ventilation slot section 443, and the other end of the fourth ventilation slot section 444 extends in the longitudinal direction of the housing 1 and penetrates the above-described one side surface of the atomizing core fixing structure 4 facing the oil reservoir 11. The ventilation groove 44 is L-shaped. Thus, the ventilation groove 44 is simple in structure and convenient to process.
According to some embodiments of the present invention, the connection location of the ventilation groove 44 and the ventilation hole 43 is remote from the oil reservoir 11 with respect to the ventilation hole 43. So configured, when the tobacco tar in the oil storage bin 11 flows into the ventilation groove 44 and enters the atomization bin 13 through the ventilation hole 43, the tobacco tar enters the ventilation hole 43 from the ventilation groove 44 to enter the high position from the low position because the ventilation hole 43 is positioned higher and closer to the oil storage bin 11, so that the medium to be atomized in the oil storage bin 11 can be prevented from flowing into the atomization bin 13 through the ventilation groove 44 and the ventilation hole 43, and the inhalation of the medium to be atomized when the user sucks can be avoided.
According to some specific embodiments of the present invention, the elastic seal 5 includes an end seal portion 51, a first seal portion 52, and a second seal portion 53, the end seal portion 51 covering at least an edge portion of a side surface of the atomizing core fixing structure 4 facing the oil reservoir 11. The first sealing portion 52 and the second sealing portion 53 are connected to the end sealing portion 51 and located on the outer peripheral side of the atomizing core fixing structure 4, a ventilation passage 6 is provided between the first sealing portion 52 and the atomizing core fixing structure 4, and the largest dimension of the second sealing portion 53 in the longitudinal direction of the housing 1 is smaller than the largest dimension of the first sealing portion 52 in the longitudinal direction of the housing 1. Referring to fig. 1 and 3, the end sealing portion 51 may overlap one end of the atomization core fixing structure 4 adjacent to the oil storage compartment 11 to firmly mount the elastic sealing member 5 on the atomization core fixing structure 4, and meanwhile, the first sealing portion 52 and the second sealing portion 53 may be both sleeved on the outer circumferential side of the atomization core fixing structure 4, and the atomization core fixing structure 4 may avoid sealing connection with the inside of the housing 1 through the first sealing portion 52 and the second sealing portion 53, so that the medium to be atomized in the oil storage compartment 11 may be prevented from flowing from the gap between the atomization core fixing structure 4 and the inner wall surface of the housing 1 to the atomization compartment 13.
Further, referring to fig. 1, the first sealing portion 52 covers the ventilation hole 43 and the ventilation groove 44. When the pressure of the oil storage bin 11 is greater than or equal to the pressure of the atomization bin 13, the first sealing part 52 seals the ventilation holes 43 and the ventilation grooves 44 and forms the ventilation channel 6, so that the waste of the medium to be atomized caused by the medium to be atomized in the oil storage bin 11 flowing to the atomization bin 13 is avoided. When the pressure of the oil reservoir 11 is smaller than the pressure of the atomizing reservoir 13, the first seal 52 is deformed, and the ventilation passage 6 is opened at this time to balance the pressures of the oil reservoir 11 and the atomizing reservoir 13.
Further, the first sealing portion 52 has a first sealing rib 521 extending in the circumferential direction of the atomizing core fixing structure 4 on the outer circumferential surface, and the second sealing portion 53 has at least one second sealing rib 531 extending in the circumferential direction of the atomizing core fixing structure 4 on the outer circumferential surface, and the second sealing rib 531 is connected to the first sealing rib 521. For example, in the example of fig. 14 to 17, the second sealing rib 531 is one, the first sealing rib 521 is located at an edge of the end of the first sealing part 52 away from the suction port 141, and the second sealing rib 531 is located at an edge of the end of the second sealing part 53 away from the suction port 141. Thus, by providing the first sealing rib 521 and the second sealing rib 531, the first sealing portion 52 and the second sealing portion 53 are in interference fit with the inner wall surface of the housing 1, so that the tightness between the atomizing core fixing structure 4 and the inner wall surface of the housing 1 can be improved, and leakage of the medium to be atomized in the oil reservoir 11 into the atomizing reservoir 13 can be avoided.
According to some embodiments of the present invention, the outer circumferential surface of the atomizing core fixing structure 4 is provided with the boss 45, and the boss 45 includes the first boss 451 and the second boss 452 connected to each other, and the height of the first boss 451 is greater than the height of the second boss 452. Referring to fig. 9 to 13, the first boss 451 is provided around the outer peripheral side of the atomizing core mounting chamber 41, the second boss 452 is provided around the outer peripheral side of the ventilation chamber 42, and the distance between the first boss 451 and the surface of the atomizing core fixing structure 4 adjacent to the oil reservoir 11 in the thickness direction is smaller than the distance between the second boss 452 and the surface of the atomizing core fixing structure 4 adjacent to the oil reservoir 11 in the thickness direction. When mounted, the free end of the first sealing portion 52 abuts against the second boss 452, and the free end of the second sealing portion 53 abuts against the first boss 451. Thereby, the elastic sealing portion can be prevented from being reversed during the installation, so that the assembly efficiency of the atomizing device 100 can be improved.
According to some embodiments of the present invention, as shown in fig. 14-17, the end seal 51 has at least one ventilation elastic portion 511, the at least one ventilation elastic portion 511 covering an end of the ventilation channel 6 facing the oil reservoir 11. When the pressure of the atomization bin 13 is greater than the pressure of the oil storage bin 11, the ventilation elastic part 511 deforms under the action of the pressure difference of the atomization bin 13 and the oil storage bin 11 to open the ventilation channel 6, and when the pressure of the atomization bin 13 is not greater than the pressure of the oil storage bin 11, the ventilation elastic part 511 seals the ventilation channel 6. The ventilation elastic portion 511 closes the ventilation channel 6 under the action of its own elastic restoring force, so that the ventilation elastic portion 511 seals the ventilation channel 6.
It should be noted that, since a certain force is required to push the ventilation elastic portion 511 to elastically deform, when the pressure difference between the atomization bin 13 and the oil storage bin 11 can push the ventilation elastic portion 511 to elastically deform, the ventilation channel 6 can be opened, that is, by setting the material and structure of the ventilation elastic portion 511, the ventilation elastic portion 511 can be pushed to open the ventilation channel 6 while the pressure of the atomization bin 13 is greater than the pressure of the oil storage bin 11, and the ventilation elastic portion 511 can be pushed to open the ventilation channel 6 when the pressure difference between the atomization bin 13 and the oil storage bin 11 reaches a certain value.
According to some embodiments of the present invention, the atomizing device 100 for an electronic cigarette further includes a baffle 46, and the baffle 46 is disposed at a communication place of the air passage 12 and the atomizing bin 13. Referring to fig. 10-12, the baffle 46 is disposed on a side of the atomizing core fixing structure 4 adjacent to the air passage 12, while the baffle 46 is disposed on a side of the atomizing core fixing structure 4 adjacent to the atomizing bin 13 in the thickness direction, and the free end of the baffle 46 extends in a direction toward the atomizing bin 13, so that the baffle 46 can block the air flow flowing from the atomizing bin 13 to the air passage 12, thereby slowing down the flow rate of the air flow, fully mixing the atomizing medium in the air flow with the air, and ensuring the experience feeling when the user sucks.
Further, as shown in fig. 4 and 5, the housing 1 includes a casing 14 and a base assembly 7, one end of the casing 14 in the length direction is provided with an opening 142, the other end of the casing 14 in the length direction is provided with an air suction port 141, the base assembly 7 is covered at the opening 142, the air suction port 71 is formed in the base assembly 7, and the atomizing bin 13 is defined by the casing 14, the atomizing core 3 and the base assembly 7 together. By such arrangement, the air inlet 71 is arranged adjacent to the atomization bin 13, so that when the atomization device 100 works, external air can be ensured to quickly enter the atomization bin 13 to be mixed with atomization medium, and meanwhile, the mixed air in the atomization bin 13 can be ensured to quickly flow to the air passage 12.
In some alternative embodiments, the free ends of the baffles 46 extend beyond the end surfaces of the side walls of the air passageway 12. Referring to fig. 1, that is, the minimum distance between the end of the baffle 46 adjacent to the base assembly 7 and the base assembly 7 is smaller than the minimum distance between the end of the air passage 12 adjacent to the base assembly 7 and the base assembly 7. Thus, the baffle 46 can block the air flow in the atomizing bin 13 when the air flows to the air passage 12, so as to slow down the flow rate of the air flow, and the atomized medium and the air can be fully mixed in the atomizing bin 13.
According to some embodiments of the present invention, the atomizing device 100 for an electronic cigarette further includes an atomizing core seal 9, and the atomizing core seal 9 is sleeved on the outer edge of the atomizing core 3 to form a seal.

The oil reservoir 11, the atomizing core 3, the atomizing core fixing structure 4 and the elastic sealing member 5 are located on one side of the partition rib 15 in the length direction of the housing 1, and the air passage 12 is located on the other side of the partition rib 15 in the width direction of the housing 1. For example, in the example of fig. 1, the oil storage bin 11, the atomizing core 3 and the atomizing core fixing structure 4 are arranged along the length direction of the housing 1, the atomizing core 3 is located at one end of the oil storage bin 11 adjacent to the atomizing bin 13, and the air passage 12 and the oil storage bin 11 are arranged along the width direction of the housing 1, so that the structural compactness of the atomizing device 100 is ensured. Wherein, the baffle 46 may be disposed at an end (not shown) of the partition rib 15 adjacent to the base assembly 7, specifically, the baffle 46 may be a junction member integrally formed with the partition rib 15, for example, a free end of the partition rib 15 may extend toward the base assembly 7, and the free end of the partition rib 15 exceeds a lower end surface of the atomizing core fixing structure 4, and the free end of the baffle 46 extends in a direction toward the base assembly 7 to block the air flow flowing toward the air passage 12.
Further, the free end of the baffle 46 extends beyond the lower end face of the atomizing core fixing structure 4. In other words, the minimum distance between the end of the baffle 46 adjacent to the base assembly 7 and the base assembly 7 is smaller than the minimum distance between the end of the atomizing core fixing structure 4 adjacent to the base assembly 7 and the base assembly 7. Thereby, the shielding of the air flow to the air passage 12 is realized, the flow speed of the air flow is slowed down, and the atomization medium and the air can be fully mixed.

The mixed smoke flows to the air passage 12 through the outlet 2 of the atomization bin, and the smoke in the air passage 12 flows to the oral cavity of the user through the inhalation passage 145 and the inhalation port 141. Along with the generation of the atomized medium, the medium to be atomized in the oil storage bin 11 is gradually adsorbed to the atomization surface, the air pressure in the oil storage bin 11 is reduced and negative pressure is formed, the air pressure in the atomization bin 13 is higher, at this time, the air flow in the atomization bin 13 can flow to the air exchange groove 44 through the air exchange cavity 42 and the air exchange hole 43, and the air flow in the air exchange groove 44 can push the air exchange elastic part 511 to deform so as to open the air exchange channel 6, so that the air pressure balance of the oil storage bin 11 and the atomization bin 13 is realized.
