In the present embodiment, the end of the bracket 13 is provided with an air inlet hole 132, and the axis of the air inlet hole 132 is parallel to the axis of the bracket 13; and the air inlet hole 132 is in direct communication with the atomizing chamber 140. The housing groove 131 of the bracket 13 has a vent groove 1313, a housing groove 1315, a sensing groove 1315a, and a noise reduction groove 1314 on the wall surface. In other embodiments, the airflow channel, the sensing chamber, the sensing channel and the silencing chamber may be directly formed on the bracket 13, and the specific structures of the airflow channel, the sensing chamber, the sensing channel and the silencing chamber are described in detail only by taking the case that the ventilation slot 1313, the accommodating slot 1315, the sensing slot 1315a and the silencing slot 1314 are formed on the wall surface of the accommodating slot 131.

The air flow sensor 15 closes the air vent groove 1313 to form an air flow passage having an orifice 1312 and a communication hole 1311. The communication hole 1311 is for making the airflow passage communicate with the outside, that is, the communication hole 1311 is for making the ventilation groove 1313 communicate with the outside; the external air flows into the gas flow path through the gap between the second housing 112 and the bracket 13 and the communication hole 1311. The air flow channel is communicated with the air inlet hole 132, and air in the air flow channel enters the atomization cavity 140 through the air inlet hole 132. Alternatively, the communication hole 1311 and the orifice 1312 are provided on the bottom wall of the vent groove 1313. Wherein, in order for the airflow sensor 15 to better sense airflow changes, to increase suction sensitivity, the airflow needs to be throttled before entering the nebulization chamber 140; in this embodiment, the throttle is throttled at the throttle hole 1312, and the sectional area at the throttle hole 1312 is the minimum sectional area of the air flow passage; the sectional area at the communication hole 1311 is the maximum sectional area of the air flow passage to have a large air flow area before the orifice 1312, reducing the suction resistance.

In other embodiments, the air inlet 132 is not required to be provided on the bracket 13, the orifice 1312 is directly connected to the atomizing chamber 140, and the air directly enters the atomizing chamber 140 through the orifice 1312.

The electronic atomizing device is provided with at least one airflow channel, and each airflow channel is provided with an outlet. Optionally, the outlet of the airflow channel is an orifice 1312. It should be noted that, when the electronic atomization device has a plurality of air flow channels, the outlets of each air flow channel are independent from each other, and the outlets of the air flow channels are the same relative to the outlets of the air flow channels, so that air flow opposite flushing of the air of different air flow channels at the outlets can be avoided, impact noise is reduced, and suction noise is also reduced.

The air flow sensor 15 closes the sensing groove 1315a to form a sensing channel for sensing air pressure at the orifice 1312 by the sensing surface of the air flow sensor 15; the air flow sensor 15 closes the accommodation groove 1315 to form a sensing chamber, which communicates with a sensing channel (i.e., the accommodation groove 1315 communicates with the sensing groove 1315 a), through which the sensing chamber senses the air pressure at the orifice 1312. It should be noted that, only the sensing channel can also realize the sensing of the airflow sensor 15, the sensing cavity is of an optional structure, and whether the sensing cavity is arranged is specifically judged according to the requirement; by arranging the sensing cavity, the sensing area of the airflow sensor 15 can be increased, and the airflow sensor 15 can sense the change of air pressure better.

The air flow sensor 15 closes the noise reduction groove 1314 to form a noise reduction chamber, which communicates with the orifice 1312 to reduce noise at the orifice 1312, thereby reducing suction noise. Wherein, the side wall of the silencing groove 1314 near the orifice 1312 is provided with a first opening 1314a so that the silencing groove 1314 communicates with the orifice 1312; the first opening 1314a may be a through hole or a notch, and as shown in fig. 3, the first opening 1314a is a notch and is closed by the airflow sensor 15 to form a channel communicating with the orifice 1312.

Noise is easy to generate when the flow speed of the air flow is high, the flow area at the throttle hole 1312 is minimum, the noise is maximum, and the throttle hole 1312 is silenced through the silencing cavity, so that the noise is reduced. The air in the air flow channel is similar to a piston, and has certain sound quality; the silencing cavity is similar to a spring and has certain sound smoothness. When the sound wave is incident into the first opening 1314a of the silencing cavity, a part of sound energy will be reflected back to the sound source due to the sudden change of the acoustic impedance, meanwhile, under the action of the sound wave, the gas in the airflow channel vibrates, and the friction damping during vibration converts a part of sound energy into heat energy to be dissipated, so that the silencing effect is realized.

The silencing frequency of the silencing cavity is related to factors such as the sectional area of the first opening 1314a, the length of the first opening 1314a, the volume of the silencing cavity and the like, and the specific silencing frequency of the silencing cavity can be designed by adjusting the parameters, so that the frequency of the incident sound wave of the silencing cavity is the same as that of the silencing cavity, resonance is formed, and a better silencing effect is achieved. The highest noise frequency is obtained by collecting the noise frequency spectrum of the orifice 1312 area, and the frequency of the silencing cavity is set to be the highest noise frequency, so that a good silencing effect can be achieved.
