[0018] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0019] Please refer to Figures 1-9 The present application provides the following technical solutions: a manual self-closing air outlet, comprising a knob assembly 2, a secondary blade group 4, a blade support 5 and a connecting rod 6. The secondary blade group 4 is connected to the blade support 5 on both sides. The number of the secondary blade group 4 is set according to actual needs. Each secondary blade group 4 is connected to the blade support 5 on both sides and rotates on the blade support 5. The connecting rod 6 is connected to one side of the secondary blade group 4, and each secondary blade group 4 is equipped with one connecting rod 6. The connecting rod 6 is designed to drive the secondary blade group 4 to rotate synchronously. The knob assembly 2 is connected to the secondary blade group 4 on the lower side and drives the secondary blade group 4 to rotate. The knob assembly 2 is designed according to the number of the secondary blade group 4. Each secondary blade group 4 is equipped with one knob assembly 2. The cantilever pressing structure is arranged on one side of the blade support 5 and the secondary blade group 4. When the secondary blade group 4 is closed, the cantilever pressing structure makes the secondary blade group 4 tightly closed. At this time, the blades on the secondary blade group 4 are sequentially overlapped on the previous blade to form a tightly closed state, optimizing the leakage under the closed state of the air outlet.

[0020] Specifically, the cantilever pressing structure comprises a cantilever 51 and a shaft 43. One side of the blade of the secondary blade group 4 is provided with the shaft 43, which is designed in the upper middle part of the blade. The blade support 5 is provided with the cantilever 51 matched with the shaft 43. The cantilever 51 is arc-shaped, and the blade support 5 below the cantilever 51 is provided with an arc-shaped track 54 for the shaft 43 to slide. The lower surface of the arc-shaped track 54 is the body of the blade support 5. In this embodiment, as shown in the drawings, the cantilever 51 is provided with a plurality of arc-shaped tracks 54, and the shaft 43 is provided with a plurality of arc-shaped protrusions 44 matched with the arc-shaped tracks 54. Figure 5As shown, the end of the cantilever 51 is open to the body of the blade support 5, and in another embodiment, the end of the cantilever 51 can be connected to the body of the blade support 5 to form a closure. In both embodiments, the shaft 43 is inserted into and rotates and slides in the arc-shaped track 54 without sliding out of the blade support 5. The inside of the end of the cantilever 51 is provided with an arc-shaped groove 52, and the inside of the cantilever 51 gradually widens to the side of the end and forms a sharp point 53 at the end of the arc-shaped groove 52. During the closing movement of the blade, the shaft 43 rotates and slides with the blade, and the cantilever 51 gradually increases the interference. When the shaft 43 moves to the sharp point 53, the cantilever 51 rebounds to generate a lateral pressing force on the shaft 43, which is pressed into the arc-shaped groove 52, thereby promoting the movement of the blade to the specified closed position. At the same time, when the blade is about to close, a self-adsorbing effect is generated to achieve a more ideal closed state. The cantilever compression structure not only has a simple structure, but also increases the locking feel. Since each blade of the secondary blade group 4 is driven to rotate synchronously by the connecting rod 6, when one blade is tightly closed, the remaining blades are also in a tightly closed state. Moreover, the blades on the secondary blade group 4 are sequentially overlapped on the previous blade, thereby optimizing the leakage under the closed state of the air port. In addition, the number of cantilever compression structures can be increased or decreased according to actual needs, and they can be designed on the side of each blade or on the side of one blade.

[0021] Specifically, the secondary blade group 4 is installed inside the rear housing 1 through the blade support 5 on both sides. The blade support 5 is fixed on the rear housing 1 and does not move. The upper blade group 3 is installed on the upper surface of the rear housing 1. The upper side of the knob assembly 2 is clamped on the upper blade group 3. In addition, the knob assembly 2 slides left and right on the upper blade group 3 to drive the secondary blade group 4 to rotate. The upper blade group 3 includes a plurality of upper blades. The number of the secondary blade group 4, the knob assembly 2, and the connecting rod 6 is consistent. The secondary blade group 4 includes a linkage blade 42 and a plurality of secondary blades 41. The linkage blade 42 and the plurality of secondary blades 41 are sequentially and intermittently arranged from left to right. The linkage blade 42 and the plurality of secondary blades 41 are provided with a center shaft 44 on both sides. The blade support 5 is provided with a plurality of holes 55 matched with the center shaft 44. The center shaft 44 is inserted into the hole 55 to movably connect the linkage blade 42 and the plurality of secondary blades 41 to the blade support 5. When the linkage blade 42 and the plurality of secondary blades 41 rotate, they rotate around the center shaft 44. After rotating and closing, the secondary blade group 4 is sequentially overlapped to optimize the leakage under the closed state of the air port.

[0023] The utility model motion process is: when needing to close the air port, knob 21 is pushed to slide on a blade, the U-shaped fork 221 under knob base 22 pushes linkage rod 421 to make linkage blade 42 rotate, under the action of connecting rod 6, a plurality of vice blades 41 are driven to rotate, the shaft 43 on vice blade group 4 rotates and slides in arc track 54 along with the blade, the interference amount of cantilever 51 is gradually increased in the closing process, when the shaft 43 moves to the cusp 53, the rebound of cantilever 51 will produce lateral extrusion force to the shaft 43, so that it is extruded into arc groove 52, thereby prompting the blade to move to the position of the specified closing, when the blade is about to close, the effect of independent "adsorption" is generated, reaches the more ideal closing state, the blade on vice blade group 4 is sequentially lapped on the previous blade, so that the leakage under the air port closing state is optimized;When needing to open the air port, knob 21 is pushed to slide on a blade to the other side, the U-shaped fork 221 under knob base 22 pushes linkage rod 421 to make linkage blade 42 rotate, under the action of connecting rod 6, a plurality of vice blades 41 are driven to rotate, the shaft 43 on vice blade group 4 reversely rotates and slides in arc track 54 along with the blade, and then the air port is opened.
