Thus, the cross-sectional areas of the outlet 2 of the atomization chamber, the air channel 12 , the suction channel 145 and the suction port 141 can be designed more reasonably.

For example, when the ratio of the absolute value of the difference between the cross-sectional area of the airway 12 and the cross-sectional area of the inhalation port 141 to the cross-sectional area of the airway 12 is less than or equal to 20%, it indicates that the cross-sectional area of the airway 12 and the inhalation The cross-sectional area of the port 141 is not much different, and the atomized medium can flow smoothly in the air channel 12 . Therefore, when the atomization device 100 is working, it can ensure that the air in the atomization chamber 13 is fully mixed with the atomized smoke and flows smoothly to the air channel 12 and then reaches the suction port 141, which can reduce the resistance of the user when inhaling. , and at the same time, it can prevent the mixed air flow from forming condensate in the air channel 12, thereby preventing the user from inhaling liquid e-liquid when smoking, and improving the user experience.

The following describes the working process when the atomizing device 100 is applied to electronic cigarettes with an example.

After the atomizing device 100 is combined with the cigarette rod, the user inhales air through the suction port 141. At this time, the pneumatic sensor (such as a microphone) in the cigarette rod senses, so that the power supply in the cigarette rod and the atomizing core 3 are electrically connected. The atomizing core 3 works, for example, the atomizing core 3 is heated, and the medium to be atomized in the oil storage chamber 11, such as smoke oil, moves toward the atomizing chamber 13 and is heated by the atomizing core 3, forming smoke in the atomizing chamber 13 (including But not limited to aerosol, suspended liquid, low-temperature steam and volatile gas), at the same time, the outside air enters the atomization chamber 13 through the air inlet 71 and mixes with the smoke in the atomization chamber 13, and the mixed smoke is atomized The chamber outlet 2, the air channel 12 and the inhalation channel 145 are inhaled by the user through the inhalation port 141 to meet the user's needs. When the user stops inhaling air from the suction port 141, the medium to be atomized in the oil storage compartment 11, such as e-liquid, will stop entering the atomization compartment 13 from the atomizing core 3, so as to avoid the liquid to be atomized in the oil storage compartment 11. Ineffective consumption of medium improves the utilization rate of the medium to be atomized. Among them, what needs to be explained here is that some electronic cigarettes set the atomizing device 100 and the tobacco rod into a separate structure, and the two are detachably combined, and some electronic cigarettes set the atomizing device 100 and the tobacco rod in a non-detachable structure. No specific limitation is made here.

According to the atomizing device 100 for electronic cigarettes according to the embodiment of the present disclosure, the difference between the cross-sectional areas of at least two of the atomization chamber outlet 2, the air channel 12, the suction channel 145 and the suction port 141 is less than or Equal to 20%, it can ensure that the mixed airflow in the atomization chamber 13 can flow smoothly to the airway 12, which can reduce the resistance of the user when inhaling, prevent the mixed airflow from forming condensate in the airway 12, and improve the user experience.

According to some embodiments of the present disclosure, the absolute value of the difference between the cross-sectional areas of any two of the atomization chamber outlet 2 , the air channel 12 , the suction channel 145 and the suction port 141 is the same as that of the air channel 12 and the suction port 141 The ratio of the cross-sectional area of any one of them is less than or equal to 20%. Among them, the first type can be that the ratio of the absolute value of the difference between the cross-sectional area of the atomization chamber outlet 2 and the air passage 12 to the cross-sectional area of any one of the air passage 12 and the suction port 141 is less than or equal to 20%; the second One can be that the ratio of the absolute value of the difference between the cross-sectional area of the atomization chamber outlet 2 and the suction channel 145 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%; the third can be The ratio of the absolute value of the difference between the cross-sectional area of the atomization chamber outlet 2 and the suction port 141 to the cross-sectional area of any one of the air passage 12 and the suction port 141 is less than or equal to 20%; the fourth type can be air The ratio of the absolute value of the difference between the cross-sectional area of the channel 12 and the suction channel 145 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%; The ratio of the absolute value of the difference in the cross-sectional area of the gas 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%; the sixth type can be the suction channel 145 and the suction port 141 The ratio of the absolute value of the difference in cross-sectional area to the cross-sectional area of any one of the airway 12 and the suction port 141 is less than or equal to 20%.

When S ₁ < 3mm ² , the cross-sectional area of the outlet 2 of the atomization chamber is small, and the mixed airflow in the atomization chamber 13 is not easy to flow to the airway 12, which will increase the resistance of the user when inhaling and affect the user experience; when S When ₁ > 6mm ² , the cross-sectional area of the outlet 2 of the atomization chamber is relatively large, so that the atomization medium in the atomization chamber 13 flows to the air channel 12 without being fully mixed with the air, which also affects the user experience. When S ₂ <3mm ² , the cross-sectional area of the airway 12 is smaller, and the airway 12 is narrower at this time, so that the user can inhale less smoke when inhaling; when S ₂ >6mm ² , the airway 12 has a larger cross-sectional area, which will increase the resistance when the user sucks.

When S ₃ <3mm ² , the cross-sectional area of the inhalation channel 145 is small, and the mixed airflow of the air channel 12 is not easy to flow to the inhalation channel 145, which will increase the resistance of the user when inhaling and affect the user experience; when S ₃ > 6mm ² , the cross-sectional area of the inhalation channel 145 is relatively large, so that the user will inhale a large amount of smoke when inhaling, which will also affect the experience of the user. When S ₄ <3mm ² , the cross-sectional area of the suction port 141 is smaller, so that the user can inhale less smoke when inhaling. In addition, when the user inhales with greater force, the user may Choked by smoke; when S ₄ >6mm ² , the cross-sectional area of the suction port 141 is larger, which will increase the resistance of the user when inhaling.

Wherein, the cross-sectional areas of the outlet 2 of the atomization chamber, the air channel 12, the suction channel 145 and the suction port 141 can be all equal, so that the mixed airflow in the atomization chamber 13 can flow smoothly to the user's mouth when the user inhales.

Therefore, by making S ₁ , S ₂ , S ₃ , and S ₄ 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 design of the cross-sectional area of the outlet 2 of the atomization chamber, the air channel 12, the suction channel 145 and the suction port 141 can be reasonably designed, while ensuring that the atomizing medium can be fully mixed with the air, it can Reduce the resistance of the user when inhaling, the mixed airflow in the atomization chamber 13 can quickly and smoothly flow to the user's mouth through the inhalation port 141, and the user can inhale an appropriate amount of smoke when inhaling, thereby improving the user experience

In other words, the suction port 141 is located in the middle of one end of the housing 1 . The central axis of the air passage 12 may be located on the left or right of the central axis of the housing 1 . Thus, when the user inhales through the inhalation port 141, the smoke in the atomization chamber 13 can flow to the middle of the user's oral cavity more smoothly after passing through the air channel 12 and the inhalation channel 145, and the smoke can be evenly distributed in the mouth. In the mouth of the user, the user experience is further improved.

The atomizing core fixing structure 4 can be sealed and connected with the inner wall surface of the housing 1 through the elastic seal 5, so that the medium to be atomized in the oil storage tank 11 can be prevented from being separated from the atomizing core fixing structure 4 and the inner wall surface of the housing 1. The gap flows into the atomization chamber 13, thereby avoiding the waste of the medium to be atomized.

The air in the atomization chamber 13 enters the atomization chamber 13 after being diverted by the first air-guiding metal plate 74, and the baffle 46 can slow down the flow velocity of the atomization medium and air, so that the atomization medium and air in the atomization chamber 13 can be fully mixed . The mixed smoke flows to the air channel 12 through the outlet 2 of the atomization chamber, and the smoke in the air channel 12 flows to the mouth of the user through the inhalation channel 145 and the inhalation port 141 . Among them, with the generation of atomizing medium, the medium to be atomized in the oil storage bin 11 is gradually absorbed to the atomizing surface, the air pressure in the oil storage bin 11 drops and a negative pressure is formed, and the air pressure in the atomizing bin 13 is relatively high. At this time, the airflow in the atomization chamber 13 will flow to the ventilation groove 44 through the ventilation cavity 42 and the ventilation hole 43, and the airflow in the ventilation groove 44 will push the ventilation elastic part 511 to deform to open the ventilation channel 6, The air pressure balance between the oil storage bin 11 and the atomizing bin 13 is realized. When the air pressure of the atomization chamber 13 and the liquid storage chamber are balanced, the ventilation elastic part 511 returns to its original state, and the end of the ventilation groove 44 adjacent to the oil storage chamber 11 is blocked to prevent the medium to be atomized in the oil storage chamber 11 leakage.
