Similarly, when the annular air channel 221 is disposed on the inner peripheral surface of the housing 10, the annular air channel 221 extends on the inner peripheral surface of the housing 10 along the central axis direction of the atomizing core fixing support 22, and the principle of communicating and blocking the atomizing bin 14 and the oil storage bin 13 is the same as the principle that the annular air channel 221 is disposed on the atomizing core fixing support 22, and will not be described again. In the present embodiment, the annular air passage groove 221 is provided on the outer peripheral surface of the atomizing core fixing support 22 as an example.

According to the atomizing device 100 of the embodiment of the utility model, the annular air channel 221 is arranged between the outer peripheral surface of the atomizing core fixing support 22 and the shell 10, so that external air flow can conveniently enter the oil storage bin 13 from the air inlet 11 to balance the pressure in the oil storage bin 13, the medium to be atomized stored in the oil storage bin 13 can smoothly flow to the atomizing core 21, so that the atomizing core 21 can work normally, and meanwhile, the path length of the external air flow flowing to the oil storage bin 13 can be increased by the annular air channel 221, so that the annular air channel 221 has the effects of oil storage and flow resistance, and the medium to be atomized in the oil storage bin 13 is prevented from leaking from the annular air channel 221.

In some embodiments, as shown in fig. 3 and 4, the annular air passage grooves 221 are plural and spaced apart in the fitting direction a of the housing 10, and adjacent two of the annular air passage grooves 221 communicate with each other. The atomizing core fixing support 22 is installed into the housing 10 from one end of the air inlet 11 of the housing 10, a plurality of annular air passage grooves 221 are provided on the atomizing core fixing support 22, each annular air passage groove 221 extends on the outer peripheral surface of the atomizing core fixing support 22 in the direction of the central axis of the atomizing core fixing support 22, and the plurality of annular air passage grooves 221 are provided at intervals and communicate on the atomizing core fixing support 22 in the direction of the central axis of the atomizing core fixing support 22, that is, in the assembling direction a of the housing 10. Alternatively, the plurality of annular air passage grooves 221 may be air passage grooves extending spirally on the outer peripheral surface of the atomizing core fixing support 22 around the central axis of the atomizing core fixing support 22. Therefore, the annular air channel grooves 221 are arranged into a plurality of paths which are communicated with each other, so that the air flow flowing on the outer peripheral surface of the atomizing core fixing support 22 can be increased, the storage capacity of the air flow in the flowing path is sufficient, the balance of the air pressure in the oil storage bin 13 is convenient to realize, the possibility that the medium to be atomized in the oil storage bin 13 flows out of the annular air channel grooves 221 is reduced, the speed of the air flow flowing in the annular air channel grooves 221 and the flowing path can be increased by the annular air channel grooves 221 which are communicated with each other, the speed of the pressure difference balance in the oil storage bin 13 is increased, the medium to be atomized in the oil storage bin 13 can flow to the atomizing core 21 quickly, and the use experience of users is improved.

Alternatively, as shown in fig. 5, at least three annular gas passage grooves 221 are provided, and two adjacent annular gas passage grooves 221 are communicated by at least one communication groove 222, and the communication grooves 222 on two adjacent annular gas passage grooves 221 are staggered in the assembling direction a perpendicular to the housing 10. For example, three annular air passage grooves 221 are provided at intervals along the fitting direction a of the housing 10, and a communication groove 222 is provided between each adjacent two of the annular air passage grooves 221, the communication groove 222 communicating the outside air flow with the annular air passage grooves 221, and simultaneously communicating the annular air passage grooves 221 with the oil reservoir 13. The communication grooves 222 provided on the adjacent two annular gas passage grooves 221 are provided at intervals in the extending direction of the annular gas passage grooves 221. Therefore, the two adjacent annular air channel grooves 221 are arranged through the communication groove 222, so that air flow can flow from one end to the other end of the atomizing core fixing support 22 along the assembling direction A of the shell 10, the efficiency of balancing the pressure in the oil storage bin 13 is improved, and the communication grooves 222 are staggered, so that the flowing time of the air flow between the two adjacent annular air channel grooves 221 can be increased, and the air flow flowing into the oil storage bin 13 in the annular air channel grooves 221 is sufficient and efficient.

In some embodiments, referring to fig. 5, the annular gas channel 221 has a width w, where w satisfies: w is more than or equal to 0.3mm and less than or equal to 0.5mm. If the width of the annular air channel 221 is smaller than 0.3mm, the airflow velocity inside the annular air channel 221 with smaller width is slower, the airflow in the annular air channel 221 is lower, the smaller airflow entering the oil storage bin 13 has weaker pressure difference balancing capability, the pressure balancing effect inside the oil storage bin 13 is worse, and the atomization efficiency of the atomization core 21 is not improved. If the width of the annular air channel 221 is greater than 0.5mm, the width of the annular air channel 221 is wider, the air flow enters the oil storage bin 13 to be larger, so that the medium to be atomized in the oil storage bin 13 flows to the atomizing core 21 too much, the medium to be atomized leaks, and the ventilation effect between the annular air channel 221 and the oil storage bin 13 is poor. For example, w=0.5 mm. Thereby, the width of the annular gas passage groove 221 is defined so that the flow effect of the gas flow in the annular gas passage groove 221 is better, and the effect of balancing the gas pressure inside the annular gas passage groove 221 and the oil reservoir 13 is better.

In some embodiments, the annular gas channel 221 has a depth h, where h satisfies: h is more than or equal to 0.3mm and less than or equal to 0.5mm. For example, h=0.5 mm. Thereby, the depth of the annular gas passage groove 221 is defined so that the flow effect of the gas flow in the annular gas passage groove 221 is better, and the balance of the gas pressure inside the oil reservoir 13 is facilitated. Here, the depth of the annular gas passage groove 221 and the width of the annular gas passage groove 221 are defined to control the flow of the gas flow in the annular gas passage groove 221, thereby improving the ventilation effect inside and outside the oil reservoir 13. Of course, the depth and width of the annular air passage groove 221 may be defined at the same time, so that the annular air passage groove 221 has a better balance effect on the air pressure in the oil reservoir 13.

In some embodiments, as shown in fig. 3 and 4, the annular air channel 221 communicates with the oil storage bin 13 through the air exchanging channel 227, the first sealing member 23 is sleeved on the end of the atomizing core fixing support 22 away from the air inlet 11, at least a part of the first sealing member 23 is located between the inner wall surface of the shell 10 and the atomizing core fixing support 22, so as to form a seal for a gap formed between the atomizing core fixing support 22 and the shell 10, reduce the possibility of leakage of medium to be atomized in the oil storage bin 13 from the gap, and increase the stability of the installation of the atomizing core fixing support 22 in the shell 10. The ventilation groove 227 is provided on the outer peripheral surface of the atomizing core fixing support 22, and extends in the assembling direction a, and the ventilation groove 227 communicates with the communication groove 222 provided on the annular air passage groove 221. The first seal member 23 is provided with at least one ventilation elastic portion 231, and the ventilation elastic portion 231 covers one end of the ventilation groove 227 facing the oil reservoir 13. The elastic part 231 of taking a breath is located the one end that atomizing core fixed bolster 22 was kept away from air inlet 11, and elastic part 231 of taking a breath is located between atomizing core fixed bolster 22 and the oil storage storehouse 13, and communicates oil storage storehouse 13 and atomizing storehouse 14. When the user sucks aerosol, the pressure inside the oil storage bin 13 is reduced, and when the pressure at the air inlet 11 is greater than the pressure of the oil storage bin 13, the ventilation elastic part 231 deforms under the action of the pressure difference of the pressure inside the air inlet 11 and the pressure difference to open the ventilation groove 227, for example, the air pressure inside the ventilation groove 227 pushes the ventilation elastic part 231 at the end part of the ventilation groove 227, and the air flow inside the ventilation groove 227 flows to the oil storage bin 13 to balance the pressure inside the oil storage bin 13. When the pressure at the air inlet 11 is not greater than the pressure of the oil reservoir 13, the ventilation elastic part 231 seals the ventilation groove 227 under the action of self elastic force.

Therefore, the air exchange groove 227 is formed in the atomization core fixing support 22, the air exchange groove 227 and the oil storage bin 13 are separated through the arrangement of the air exchange elastic part 231, so that when the air pressure in the air exchange groove 227 and the air pressure in the oil storage bin 13 generate a pressure difference, the air pressure in the air exchange groove 227 can overcome the elasticity of the air exchange elastic part 231 to push the air exchange elastic part 231 into the oil storage bin 13, the mode and the structure for balancing the air pressure in the oil storage bin 13 are simpler and more effective, and the first sealing piece 23 can form a seal for the air exchange groove 227.

In addition, if the annular air channel groove 221 is formed on the inner peripheral surface of the housing 10, the air exchanging groove 227 is formed on the atomizing core fixing support 22, the annular air channel groove 221 is communicated with the air exchanging groove 227, and when the pressure difference between the atomizing bin 14 and the oil storage bin 13 is larger than a preset value, the air entering through the air inlet 11 flows through the annular air channel groove 221 and the air exchanging groove 227 to realize the communication between the atomizing bin 14 and the oil storage bin 13, and the air pressure between the atomizing bin 14 and the oil storage bin 13 is balanced.

In some embodiments, as shown in fig. 5, one end of the ventilation groove 227 communicates with the annular gas passage groove 221, and the other end of the ventilation groove 227 penetrates a side surface of the atomizing core fixing support 22 facing the oil reservoir 13, and the first seal member 23 includes: an end seal 232 and a first seal 233, wherein the end seal 232 is provided on a surface of the atomizing core fixing support 22 facing the oil reservoir 13, and the end seal 232 covers one end of the ventilation groove 227 facing the oil reservoir 13. The first sealing portion 233 is connected to the end sealing portion 232, and the first sealing portion 233 is located between the outer peripheral surface of the atomizing core fixing support 22 and the inner wall surface of the housing 10. That is, the first sealing portion 233 forms a seal to the ventilation groove 227 at the outer periphery of the atomizing core fixing support 22, the end sealing portion 232 is connected to an end of the first sealing portion 233 remote from the air inlet 11, the end sealing portion 232 is abutted against an end of the atomizing core fixing support 22 remote from the air inlet 11, and when the atomizing core fixing support 22 is fitted into the housing 10, the first sealing portion 233 is pressed to increase the reliability of the mounting of the atomizing core fixing support 22 to the housing 10. When the air pressure in the oil storage bin 13 needs to be balanced, the air flow in the annular air channel groove 221 enters the air exchange groove 227 through the communication groove 222 and then enters the oil storage bin 13.

Therefore, the arrangement of the end sealing part 232 and the first sealing part 233 can increase the sealing of the gap between the atomizing core fixing support 22 and the shell 10 formed by the first sealing piece 23 at the end part and the outer periphery side of the atomizing core fixing support 22 and the sealing between the oil storage bin 13 and the atomizing core fixing support 22, so that the leakage of medium to be atomized in the oil storage bin 13 from the gap is effectively avoided, and the use of the atomizing device 100 is affected.

Further, as shown in fig. 5, the atomizing core fixing support 22 includes a first support portion 223 and a second support portion 224 connected to each other in the fitting direction a of the housing 10, an end seal portion 232 covers a side surface of the first support portion 223 remote from the second support portion 224, the first seal portion 233 covers an outer peripheral surface of the first support portion 223, a ventilation groove 227 is formed on the first support portion 223, and an annular gas passage groove 221 is formed on the second support portion 224.

The stopper groove 2231 is provided adjacent to the annular gas path groove 221, the stopper groove 2231 extends along the outer circumferential surface of the atomizing core fixing support 22, and the stopper groove 2231 is recessed toward the center of the atomizing core fixing support 22. The ventilation groove 227 is not in communication with the limit groove 2231. The end of the first sealing part 233 far away from the end sealing part 232 is provided with a limiting protrusion 2331, the limiting protrusion 2331 is arranged on one side of the first sealing part 233 adjacent to the ventilation groove 227, and when the first sealing piece 23 is assembled with the atomizing core fixing support 22, the limiting protrusion 2331 is matched with the limiting groove 2231, so that the tightness and reliability of the assembly between the first sealing piece 23 and the fixing of the atomizing core 21 are improved.
