[0029] Please refer to Figure 1-4 The utility model proposes an atomization device for reducing airflow whistling, comprising a shell 1 and an atomization assembly 2 having an atomization channel 21. The atomization assembly 2 is installed in the shell 1. The shell 1 is provided with an air inlet channel 121, a first end of the air inlet channel 121 is connected to the atomization channel 21, and a second end is connected to the outside air. A plurality of air holes 123 are provided at intervals on the side wall of the air inlet channel 121. By providing a plurality of air holes 123 on the side wall of the air inlet channel 121, when the air flow in the air inlet channel 121 passes through the air holes 123, part of the air flow and noise enter the air holes 123, the sound waves interfere and cancel each other out, and thus the air flow noise is reduced.

[0030] In some embodiments, Figure 1-3 As shown, the housing 1 includes a shell 11 and a bracket 12. The bracket 12 is accommodated in the shell 11. The shell 11 is provided with an air inlet 111 and a mounting portion 112 having a second vent 1121. The mounting portion 112 is used to install the atomizer assembly 2. In practical applications, the mounting portion 112 can establish a mechanical connection with the atomizer assembly 2 by magnetic attraction, thread, snap or interference fit, which can be a detachable connection or a non-detachable connection. When the atomizer assembly 2 is mounted on the mounting portion 112, the atomizer channel 21 is connected to the second vent 1121. The bracket 12 is provided with a through air inlet channel 121, one end of the air inlet channel 121 is connected to the air inlet 111, and the other end is connected to the second vent 1121. In this way, when the user inhales the atomizer assembly 2, the outside air enters the atomizer channel 21 through the air inlet 111, the air inlet channel 121, and the second vent 1121 in sequence to participate in atomization.

[0031] In some embodiments, Figure 2 and Figure 3As shown, the atomization device also includes a sealing ring 3. The sealing ring 3 is made of soft rubber material, such as silicone, rubber or silicone rubber. The sealing ring 3 includes a sealing ring body, and the sealing ring body is provided with a avoidance hole. The sealing ring body can be square, circular, elliptical or other regular or irregular shapes. The shape and size of the avoidance hole are adapted to the end of the bracket 12 away from the air inlet 111. The sealing ring 3 is sleeved on the bracket 12 through the avoidance hole, and the avoidance hole and the bracket 12 are interference fit. In order to prevent the sealing ring 3 from axially displacing relative to the bracket 12, the bracket 12 is provided with an annular groove (not marked in the figure) corresponding to the sealing ring 3, and the sealing ring 3 is sleeved on the bracket 12 and accommodated in the annular groove. Preferably, the thickness of the sealing ring 3 is slightly greater than the height of the annular groove along the axial direction of the bracket 12, so that the sealing ring 3 partially protrudes outside the annular groove in the axial direction. When the bracket 12 is connected to the mounting portion 112, the mounting portion 112 elastically abuts against the protruding portion of the sealing ring 3, so that the sealing ring 3 is clamped between the bracket 12 and the mounting portion 112, and plays a role in sealing the gap between the bracket 12 and the mounting portion 112, so that the air intake channel 121 and the second air vent 1121 are sealed and connected, and the airflow in the air intake channel 121 will not flow out from the gap.

[0032] In some embodiments, Figure 2 As shown, there is a gap 4 between the outer periphery of the bracket 12 and the inner wall of the housing 11, which is connected to the outside air. The air through hole 123 passes through the side wall of the bracket 12, and one end is connected to the air inlet channel 121, and the other end is connected to the gap 4. In this embodiment, the air through hole 123 is connected to the outside air through the gap 4 between the bracket 12 and the housing 11, so that part of the air flow and sound waves flowing out of the air through hole 123 can be discharged through the gap 4.

[0033] In some embodiments, Figure 2 and Figure 4As shown, the side wall of the air inlet channel 121 is provided with a groove 122, that is, the side wall of the bracket 12 corresponding to the air inlet channel 121 is provided with the groove 122. The opening direction of the groove 122 is perpendicular to the axial direction of the air inlet channel 121 and is away from the air inlet channel 121. The plurality of air holes 123 are provided on the bottom wall of the groove 122 and penetrate the bottom wall of the groove 122. By providing the groove 122 area on the side wall of the air inlet channel 121 to open the air holes 123, on the one hand, the depth of the air holes 123 is reduced, which is conducive to improving the diffusion efficiency of the sound waves and thus improving the silencing efficiency. On the other hand, providing the groove 122 area on the side wall of the air inlet channel 121 reduces the thickness of the side wall and facilitates processing. In practical applications, a slot 124 can also be provided at the opening of the slot 122, and the slot 124 increases the gap 4 between the bracket 12 and the housing 11, thereby accelerating the diffusion of the sound waves and improving the noise reduction efficiency.

[0034] In some embodiments, in order to further improve the effect of eliminating noise, a sound absorbing member (not shown in the figure) is further contained in the groove 122. The sound absorbing member absorbs the airflow sound transmitted from the air through hole 123, thereby effectively reducing the noise. In practical applications, the sound absorbing member can be made of porous breathable materials, such as foam, etc.

[0035] In some embodiments, Figure 3 As shown, the air inlet passage 121 at least includes a first ventilation section 1211 and a second ventilation section 1212. The first ventilation section 1211 is closer to the second end of the air inlet passage 121 relative to the second ventilation section 1212. The first ventilation section 1211 is connected to the second ventilation section 1212, and a partition plate 1213 is provided between the two. The partition plate 1213 is provided with a plurality of first ventilation holes 1214, so that the first ventilation section 1211 and the second ventilation section 1212 are connected via the plurality of first ventilation holes 1214. That is, the airflow flowing from the first ventilation section 1211 can only flow into the second ventilation section 1212 from the plurality of first ventilation holes 1214. In this way, the airflow in the air inlet passage 121 is dispersed by the plurality of first ventilation holes 1214 when flowing through the partition plate 1213, which is conducive to slowing down the airflow speed, thereby reducing the airflow whistling sound. In practical applications, the plurality of air vents may be provided on the side wall of the first ventilation section 1211, or on the side wall of the second ventilation section 1212, or on the side walls of both the first ventilation section 1211 and the second ventilation section 1212. Preferably, the air vents 123 are provided on the side wall of the first ventilation section 1211, so that when the outside air enters the first ventilation section 1211, the air vents 123 are first subjected to a first noise reduction treatment, and when the outside air flows through the partition plate 1213, the second noise reduction treatment is then performed, thereby effectively improving the noise reduction effect.

[0036] In some embodiments, the inner diameter of the first ventilation section 1211 is greater than the inner diameter of the second ventilation section 1212, that is, when the airflow enters the air inlet channel 121 from the air inlet 111, the channel it flows through changes from large to small, thereby preventing the airflow from directly entering a narrow channel and producing a sharp whistle.

[0037] It is worth noting that the air inlet passage 121 may also include a third ventilation section, a fourth ventilation section, ... an Nth ventilation section sequentially connected to the second ventilation section 1212, and the first ventilation holes 1214 may be provided between each adjacent ventilation section to sequentially divert the airflow in the air inlet passage 121. In practical applications, the number, size, and distribution of the first ventilation holes 1214 may be set according to requirements and are not limited here.

[0038] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
