Description

Technical Field

[0001] The utility model relates to an aerosol generating device. Background Art

[0002] The existing aerosol generator sets a small hole in the shell as an air inlet. When the user inhales, the outside air enters the device through the air inlet and participates in atomization. However, due to the small aperture of the existing air inlet, the outside air quickly gathers in the small hole under the action of suction and flows into the device from the small hole, which makes the air pass through the narrow aperture of the small hole during the flow process and produces a sharp airflow sound.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0025] Please refer to Figure 1-5 The utility model proposes an aerosol generating device, comprising a shell 1 and an atomizing assembly 2. The atomizing assembly 2 is installed in the shell 1, and the atomizing assembly 2 is provided with a through atomizing channel 21. The shell 1 is provided with at least one air inlet hole 11 connected to the atomizing channel 21, and the inner wall of at least one air inlet hole 11 is provided with at least one convex rib 3 extending in the axial direction. The convex rib 3 convexly provided inside the air inlet hole 11 disperses the airflow entering the air inlet hole 11. After the outside air enters the air inlet hole 11, part of the airflow is dispersed by the convex rib 3 and flows along the interval gaps between the convex ribs 3, thereby effectively reducing the high-frequency noise generated by the concentrated flow of the airflow.

[0026] In some embodiments of the present invention, Figure 2-4As shown, the housing 1 is provided with a mounting groove for mounting the atomizing assembly 2. The air inlet 11 is connected to the mounting groove, and when the subsequent atomizing assembly 2 is accommodated in the mounting groove, the air inlet 11 is connected to the atomizing channel 21 via the mounting groove. In practical applications, the air inlet 11 can be located at the bottom, top, or between the top and the bottom of the housing 1. The position of the air inlet 11 can be set according to actual needs, and is not limited here. The air inlet 11 can be a circular, square, polygonal or other regular or irregular shaped hole. Preferably, the air inlet 11 is a circular hole or a runway-shaped hole, so that the inner wall of the air inlet 11 has a smooth structure, which is conducive to reducing the resistance to air flow, and thus helps to reduce the noise generated by airflow. It is worth noting that the aperture and number of the air inlet 11 can be set according to actual needs, and are not limited here.

[0027] In some embodiments, the first end 111 of the air inlet 11 is connected to the atomization channel 21 via the mounting groove, the second end 112 is exposed on the outer surface of the housing 1 and is connected to the outside air, and the aperture of the second end 112 gradually decreases in the direction away from the outer surface of the housing 1. That is, the air inlet 11 is a tapered hole, and the aperture of the air inlet 11 is the smallest at the first end 111 and the largest at the second end 112. In this way, after the airflow enters the air inlet 11 from the second end 112 with the largest aperture, it enters the atomization channel 21 from the first end 111 with the smallest aperture, which enhances the low-frequency gain of the airflow, thereby avoiding the generation of sharp airflow sound.

[0028] In some embodiments, Figure 3 As shown, the convex ribs 3 are distributed at intervals on the inner wall of the air inlet 11. The distances between each convex rib 3 and the adjacent convex ribs 3 may be equal or unequal. Preferably, the distances between adjacent convex ribs 3 are equal, so that when the airflow passes through the air inlet 11, it is evenly dispersed by the convex ribs 3 distributed at equal intervals, which is conducive to forming a stable and smooth airflow. At least one of the convex ribs 3 is distributed along a ring and forms an annular structure on the inner wall of the air inlet 11, and the center of the annular structure coincides with the center of the air inlet 11. In actual applications, the length of the convex rib 3 is less than or equal to the depth of the air inlet 11, and the length of the path can be set according to actual needs.

[0029] In some embodiments, Figure 4 and Figure 5As shown, a guide surface 31 is provided at one end of the rib 3 close to the outer surface of the shell 1. The guide surface 31 includes two opposite ends, namely a head end 311 and a second end 112. Among them, the head end 311 is connected to the inner wall of the air inlet 11. The end 312 extends toward the center direction of the air inlet 11, and gradually moves away from the outer surface of the shell 1. That is, the guide surface 31 of at least one rib 3 forms a trumpet-shaped structure. The inner diameter of the trumpet-shaped structure gradually decreases in the direction away from the outer surface of the shell 1. In other words, after entering the air inlet 11, the airflow first passes through the large diameter end of the trumpet-shaped structure, that is, the head end 311 of the guide surface 31, and then gradually gathers and flows to the end 312 of the guide surface 31 as the inner diameter of the trumpet-shaped structure decreases. In this way, part of the airflow passes through the head end 311 and the end 312 of the guide surface 31 in turn, and continues to flow through the air inlet 11. Since the guide surface 31 is a smooth slope, it guides the airflow to flow smoothly, effectively reducing the high-frequency noise generated when the airflow enters the air inlet 11, and enhancing the low-frequency gain, thereby reducing the harsh airflow sound.

[0030] 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.
