For example, "fixation" may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] Please refer to Figure 1-6 , the present utility model provides an aerosol generating device, which includes a housing 1 provided with an air inlet 11, a main body 2 provided with an air passage 22, and an adjusting member 3. The housing 1 covers the outer periphery of the main body 2 and forms an installation space 4 for installing the adjusting member 3 with the main body 2. The adjusting member 3 is slidably installed in the installation space 4, and one side hermetically covers the air passage 22, and the other side is partially exposed at the air inlet 11. The adjusting member 3 is correspondingly provided with an adjusting hole 33. When the adjusting member 3 slides in the installation space 4 until one end of the adjusting member 3 communicates with the air inlet 11 and the other end communicates with the air passage 22, outside air flows in successively through the air inlet 11, the adjusting hole 33, and the air passage 22. In this embodiment, by hermetically covering the air passage 22 with the adjusting member 3, it is ensured that the outside air flow can only be adjusted by the movement of the adjusting hole 33, which is beneficial to more precisely adjusting the air intake volume.

[0032] In some embodiments, such as Figure 2As shown, the main body 2 includes a bracket 21 and components such as a battery assembly, a display assembly, a control assembly, and an atomization assembly installed within the bracket 21. The bracket 21 is provided with a chute 211, and the outer shell 1 covers the outer periphery of the bracket 21 and encloses the installation space 4 with the chute 211. The air inlet 11 is provided on the part of the outer shell 1 that encloses the installation space 4, so that the air inlet 11 is in communication with the installation space 4. The ventilation channel 22 is provided on the bottom wall of the chute 211 and is in communication with the installation space 4. In practical applications, the ventilation channel 22 may include a first ventilation hole 221 provided on the bottom wall of the chute 211 and a second ventilation hole 222 communicating with the first ventilation hole 221. One end of the second ventilation hole 222 away from the first ventilation hole 221 extends within the main body 2 and is in communication with the atomization assembly, so that the air entering the ventilation channel 22 can flow into the atomization assembly through the second ventilation hole 222 and participate in atomization.

[0033] In some embodiments, as Figure 4-5 shown, the axial direction of the first ventilation hole 221 is parallel to the opening direction of the chute 211. When the adjusting member 3 is accommodated within the installation space 4, the adjusting member 3 is located between the air inlet 11 and the first ventilation hole 221. That is, one side of the adjusting member 3 faces the air inlet 11, and the other side faces the first ventilation hole 221. By moving the adjusting member 3, the air passage area between the air inlet 11 and the first ventilation hole 221 is adjusted, thereby adjusting the air intake. The axial direction of the air inlet 11 is parallel to the axial direction of the first ventilation hole 221, and at least part of the air inlet 11 is opposite to the first ventilation hole 221. Preferably, the central axes of the first ventilation hole 221 and the air inlet 11 coincide, that is, the first ventilation hole 221 is completely opposite to the air inlet 11. In this way, it is beneficial to increase the maximum air intake.

[0034] In some embodiments, please refer to Figure 2 、 Figure 4-Figure 6, the adjusting member 3 includes a sliding portion 31 and a lever 32. The sliding portion 31 includes a slider 311 and a sealing member 312. The size and shape of the sliding portion 31 are adapted to the installation space 4. When the slider 311 is accommodated in the installation space 4, one side of the slider 311 is attached to the housing 1, and the other side is attached to the bottom wall of the slide groove 211. Thus, the displacement of the slider 311 is limited by the slide groove 211 and the housing 1, and the sliding is guided at the same time, making the sliding smoother. The slider 311 is provided with an installation groove (not shown in the figure) on one side of the bottom wall of the slide groove 211 facing the main body 2, that is, the slider 311. The sealing member 312 is accommodated in the installation groove, and part of it protrudes out and elastically abuts against the bottom wall of the slide groove 211. Since the first vent hole 221 is disposed on the bottom wall of the slide groove 211, when the slider 311 is in a position to completely cover the first vent hole 221, the slider 311 seals the first vent hole 221, so that outside air cannot enter the air passage 22 from the gap between the slider 311 and the main body 2, thereby preventing air from entering. When the slider 311 is in a position to completely or partially open the first vent hole 221, outside air can only enter the air passage 22 through the first vent hole 221, thereby improving the efficiency of air flow.

[0035] like Figure 4-6 As shown, one end of the lever 32 is fastened to the slider 311, and the other end passes through the air inlet 11 and extends out of the housing 1 for the user to move. When the lever 32 is moved by an external force, the lever 32 moves in a direction perpendicular to the axial direction in the air inlet 11, and drives the slider 311 to move in a direction perpendicular to the axial direction of the air inlet 11, so as to completely or partially cover the air inlet 11. In practical applications, the lever 32 can be integrally connected with the slider 311, or a plug-in hole adapted to the lever 32 can be provided on the slider 311, and the lever 32 can be fastened and plugged into the plug-in hole.

[0036] The adjusting hole 33 passes through the slider 311. When the slider 311 moves along the axial direction perpendicular to the air inlet 11 driven by the lever 32, the adjusting hole 33 also moves accordingly. When the adjusting hole 33 moves to a point where one end at least partially overlaps with the air inlet 11 and the other end at least partially overlaps with the first vent 221, the air inlet 11 and the first vent 221 are connected via the adjusting hole 33, and the outside air can enter the main body 2 via the air inlet 11, the adjusting hole 33, and the first vent 221 in sequence. In this way, the overlapping area between the adjusting hole 33 and the air inlet 11 and / or the air passage 22 can be adjusted by moving the lever 32, thereby achieving the purpose of adjusting the air intake. Furthermore, the axial direction of the adjusting hole 33 is parallel to the axial direction of the air inlet 11 and the first vent 221, so that when the air flows through the air inlet 11, the adjusting hole 33, and the first vent 221 in sequence, the resistance can be reduced.

[0037] In some embodiments, Figure 3 , Figure 5 and Figure 6 As shown, since the regulating member 3 seals and covers the air passage 22, the airflow cannot flow through the installation gap of the regulating member 3, but can only enter the air passage 22 through the regulating hole 33, which will produce sharp noise. In order to eliminate the high-frequency noise generated by the airflow passing through the regulating hole 33, the inner wall of the regulating hole 33 is provided with at least one convex rib 5 extending in the axial direction. The convex rib 5 convexly arranged inside the regulating hole 33 disperses the airflow entering the regulating hole 33, thereby reducing the high-frequency noise. The convex ribs 5 are distributed at intervals on the inner wall of the regulating hole 33. The distances between each convex rib 5 and the adjacent convex ribs 5 can be equal or unequal. Preferably, the distances between adjacent convex ribs 5 are equal, so that when the airflow passes through the regulating hole 33, it is evenly dispersed by the convex ribs 5 distributed at equal intervals, which is conducive to forming a stable and smooth airflow. At least one of the convex ribs 5 is distributed along a ring and forms an annular structure on the inner wall of the regulating hole 33, and the center of the annular structure coincides with the center of the regulating hole 33. In practical applications, the length of the rib 5 is less than or equal to the depth of the adjustment hole 33, and the length of the rib 5 can be set according to actual needs.

[0038] In some embodiments, Figure 5 As shown, a guide surface 51 is provided at one end of the convex rib 5 close to the air inlet 11. The guide surface 51 includes two opposite ends, namely a first end 511 and a second end 512. The first end 511 is connected to the inner wall of the adjustment hole 33. The second end 512 extends toward the center of the adjustment hole 33, and gradually moves away from the outer surface of the housing 1. That is, the guide surface 51 of at least one convex rib 5 forms a trumpet-shaped structure. The inner diameter of the trumpet-shaped structure gradually decreases in the direction away from the air inlet 11. That is, after entering the adjustment hole 33, the airflow first passes through the large diameter end of the trumpet-shaped structure, wherein the large diameter section is surrounded by the first end 511 of each guide surface. Then it flows along each guide surface to the second end 512, that is, it gradually gathers and flows as the inner diameter of the trumpet-shaped structure decreases. In this way, after the outside air enters the adjustment hole 33, part of the airflow is dispersed by the convex rib 5 and flows along the interval gaps between the convex ribs 5, thereby effectively reducing the high-frequency noise generated by the concentrated flow of the airflow. Part of the airflow passes through the first end 511 and the second end 512 of the guide surface 51 in sequence, and continues to flow through the adjustment hole 33. Since the guide surface 51 is a smooth inclined surface, the airflow is guided to flow smoothly.

[0039] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
