[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a diffuser with variable air supply includes a diffuser 1. The diffuser 1 is arranged on the front of the car center console. A blade 2 is arranged inside the diffuser 1. The blade 2 is rotatably arranged inside the diffuser 1. By rotating the blade 2 with fingers, the direction of the air supply of the air conditioner can be adjusted. The center of the diffuser 1 is an air outlet 14, and the air outlet is circular.

[0025] In this embodiment: The driver and passengers rotate the blade 2 inside the air outlet 14 with their fingers. The direction in which the blade 2 tilts after rotation is the reverse direction of the air exhaust from the air outlet 14, which is beneficial to adjusting the direction of the air exhausted from the air outlet 14 of the diffuser 1 with fingers and realizing the operation of variable air supply.

[0026] Please refer to Figures 1 to 5 , the outside of the diffuser 1 includes an extension plate 3. A dust-proof plate 4 is rotatably connected to the top of the extension plate 3. A shielding plate 5 is rotatably connected to the front of the car center console. The purpose of the shielding plate 5 is to shield the part of the dust-proof plate 4 extending out of the extension plate 3 and the arc-shaped groove 7 to improve the appearance. The shielding plate 5 is a hollow circular ring for facilitating cooperation with the air outlet 14. A circular plate 6 is fixed to the back of the shielding plate 5. The circular plate 6 is provided with an arc-shaped groove 7. The number of convex blocks 8 fixed to the top of the dust-proof plate 4 is equal to and corresponds to the number of the arc-shaped grooves 7 one by one. The convex blocks 8 penetrate through the arc-shaped grooves 7.

[0027] In this embodiment: When the air outlet 14 is not exhausting air, the shielding plate 5 can be rotated. The purpose of the shielding plate 5 is to shield the part of the dust-proof plate 4 extending out of the extension plate 3 and at the same time shield the arc-shaped groove 7 to improve the appearance. When the shielding plate 5 rotates, it drives the circular plate 6 to rotate. When the circular plate 6 rotates, the arc-shaped groove 7 rotates accordingly. Then the arc-shaped groove 7 moves outside the convex block 8, and then multiple dust-proof plates 4 rotate synchronously to close the air outlet 14, preventing dust from entering the inside of the exhaust duct or adhering to the surface of the blade 2.

[0028] Please refer to Figures 1 to 5 , a round cover 9 is arranged on the top of the shielding plate 5. The round cover 9 can be detached from the top of the shielding plate 5. The round cover 9 is made of transparent glass and does not block light. A light bulb 11 is arranged at the bottom of the inner cavity of the shielding plate 5. A drawing board 12 is detachably arranged on the inner wall of the shielding plate 5.

[0029] In this embodiment: There is a switch provided at the central armrest console of the vehicle. By pressing the switch, the bulb 11 is turned on, and then the bulb 11 projects the picture on the drawing board 12, similar to a projection, which is convenient for children to play. The round cover 9 is made of transparent glass, so it does not affect the lighting. When the drawing board 12 needs to be replaced, just open the round cover 9 to replace the new drawing board 12, which is convenient for projecting other interesting patterns.

[0030] Working principle: The driver or passenger rotates the blade 2 inside the air outlet 14 with their finger. The direction in which the blade 2 tilts after rotation is the reverse direction of the air exhaust from the air outlet 14, which is beneficial for adjusting the air direction discharged from the air outlet 14 of the diffuser 1 through the finger to achieve the operation of variable air supply. When the air outlet 14 is not exhausting air, the baffle 5 can be rotated. The purpose of the baffle 5 is to block the part of the dust-proof plate 4 that extends out of the extension plate 3, and at the same time block the arc-shaped groove 7 to improve the aesthetics. When the baffle 5 rotates, it drives the round plate 6 to rotate. When the round plate 6 rotates, the arc-shaped groove 7 rotates accordingly, and then the arc-shaped groove 7 moves outside the convex block 8, and then multiple dust-proof plates 4 rotate synchronously to close the air outlet 14, preventing dust from entering the inside of the exhaust duct or adhering to the surface of the blade 2 to solve the problems in the background technology. There is a switch provided at the central armrest console of the vehicle. By pressing the switch, the bulb 11 is turned on, and then the bulb 11 projects the picture on the drawing board 12, similar to a projection, which is convenient for children to play. The round cover 9 is made of transparent glass, so it does not affect the lighting. When the drawing board 12 needs to be replaced, just open the round cover 9 to replace the new drawing board 12, which is convenient for projecting other interesting patterns.

[0031] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
