[0017] The present application will be described in detail below through specific examples. Example 1:

[0018] As shown in Figs. 1-5, the electronic cigarette with a structure for reducing airflow noise of the present application is composed of an atomizer 1 and a power assembly. The upper end of the atomizer 1 has a suction port 10, and the user can inhale air from the suction port 10, and the airflow in the atomizer 1 can be automatically sensed to trigger a switch to automatically start the electronic cigarette to work. When the electronic cigarette works, the atomizer 1 can automatically heat and evaporate the atomizing liquid to generate aerosol, i.e., electronic cigarette smoke, which can be discharged from the suction port 10.

[0019] The power supply assembly comprises a hollow power supply shell 2, a support 3 arranged in the power supply shell 2, a circuit board 4, also known as a PCB control board, and a battery pack 5, wherein the circuit board 4 is fixedly arranged on the support 3. The battery pack 5 can be disassembled from the power supply shell 2, and the battery pack 5 is an element integrated by assembling a charging device and a battery core. In this embodiment, in order to make the installation of the circuit board 4 more firm and reliable, a support upper cover 6 is further arranged on the support 3, the circuit board 4 is fixedly arranged between the support 3 and the support upper cover 6, and the circuit board 4 is better fixed and protected.

[0020] The connecting end of the atomizer 1 is connected with the connecting end of the power supply shell 2, the outer wall of the upper end of the support 3 is sleeved with the inner wall of the connecting end of the power supply shell 2, the end face of the upper end of the support 3 abuts against the end face of the connecting end of the atomizer 1, and the end face of the upper end of the support 3 is concavely provided with an air inlet cavity 30, so that the atomizer 1 can provide the air inlet channel arranged on the end face of the connecting end of the atomizer 1 with the air inhaled when the atomizer 1 works.

[0021] The outer wall of the upper end of the support 3 is provided with an annular groove 31, the wall portion of the power supply shell 2 is provided with a first air inlet through hole 20 corresponding to the annular groove 31 and communicating with the annular groove 31, and the bottom of the annular groove 31 is provided with a second air inlet through hole 310 and communicating with the air inlet cavity 30. When the electronic cigarette works, the atomizer 1 is sucked, the air inlet cavity 30 generates negative pressure, and the airflow flows in the airflow channel of the atomizer 1, and the airflow will accelerate when encountering a narrow place, so that the airflow noise is easily generated in the atomizer 1. In the existing electronic cigarette, the air outside directly enters the air inlet cavity 30 from the first air inlet through hole 20, and the noise generated in the atomizer 1 is directly conducted outward through the air inlet cavity 30 and the first air inlet through hole 20, so that the user can hear a large airflow noise, resulting in poor smoking experience of the user. In the present application, the structure of the annular groove 31 and the second air inlet through hole 310 is arranged, the air outside enters the annular groove 31 after the first air inlet through hole 20, the air flows in the annular groove 31 for a distance and then enters the air inlet cavity 30 through the second air inlet through hole 310, the annular groove 31 forms a buffer channel, so that the noise generated in the atomizer 1 is further conducted outward through the air inlet cavity 30, the annular groove 31 and the first air inlet through hole 20 after passing through the air inlet cavity 30, and the airflow noise is gradually weakened in the buffer channel of the annular groove 31, that is, the first air inlet through hole 20, the annular groove 31 and the second air inlet through hole 310 are the structure for reducing the airflow noise, which can reduce the transmission of the airflow noise and make the user obtain better smoking experience.

[0022] In this embodiment, the included angle between the first air inlet through hole 20 and the second air inlet through hole 310 in the circumferential direction is greater than or equal to 90 degrees, so that the direction of the airflow noise transmission forms a large included angle between the first air inlet through hole 20 and the second air inlet through hole 310, and the travel distance of the airflow noise in the annular groove 31 is long, the airflow noise can be further weakened, and better noise reduction effect is obtained.

[0023] In other embodiments, the annular groove 31 has a meandering line structure (not shown in the figures), which also increases the travel of the annular groove 31, and the airflow noise can be further reduced to achieve a better noise reduction effect.

[0024] In the present embodiment, the upper and lower sides of the annular groove 31 are also respectively provided with annular sealing grooves 32, and sealing rings 7 are arranged in the annular sealing grooves 32. The sealing rings 7 can seal the gap between the support 3 and the power shell 2. In this way, the airflow noise can be further reduced when passing through the air inlet cavity 30 or the annular sealing groove 32, and the gap between the support 3 and the power shell 2 can be prevented from conducting the airflow noise outward, so that the airflow noise can be further reduced to achieve a better noise reduction effect.

[0025] As shown in FIGS. 2-4, the A-B continuous arrow direction is the direction of the airflow from the outside to the inside of the atomizer 1 through the first air inlet through hole 20, the annular sealing groove 32, the second air inlet through hole 310, and the air inlet cavity 30, and the direction of the aerosol generated after the atomized liquid is atomized in the atomizer 1 and flows to the suction port 10.
