For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0024] An exhaust vent, such as Figure 1-Figure 4 As shown, it includes a base 1 and a cover 2, a through slot 3 is provided on the base 1, the cover 2 is detachably connected to the top of the base 1, a mounting frame 4 is fixedly connected in the through slot 3, a plurality of blades 5 are rotatably connected to the mounting frame 4 through a control member, the blades 5 abut against the inner wall of the base 1, a sealing member for connecting the blades 5 to the inner wall of the base 1 is provided on the side wall of the blade 5, a plurality of blades 5 are sequentially distributed on the mounting frame 4 from bottom to top, the through slot 3 is used for normal exhaust of the exhaust port, the blades 5 can be controlled to rotate by the control member, during the rotation process, the sides of the blades 5 can overlap each other, the sealing member can ensure that the connection between the blades 5 and the base 1 is tighter, thereby closing the through slot 3, blocking the places that do not need ventilation, and reducing the waste of fresh air.

[0025] The control member includes a plurality of connecting rings 6 and a plurality of limiting blocks 7, wherein the plurality of connecting rings 6 are fixedly connected to the plurality of blades 5, respectively, and the plurality of connecting rings 6 are sequentially sleeved on the mounting frame 4, and the connecting rings 6 are rotatably connected to the mounting frame 4, and the plurality of limiting blocks 7 are respectively fixedly connected to the top surface of one side of the blade 5, and a slide groove 8 is provided on the bottom surface of the blade 5 away from the side of the limiting block 7, and the limiting blocks 7 and the slide groove 8 on the two adjacent blades 5 are slidably connected to each other, and a rotary cover 9 for controlling the rotation of the connecting ring 6 is connected to the connecting ring 6 close to the surface cover 2, and the top surface of the blade 5 at the bottom of the base 1 is provided with a screw cap 9 for controlling the rotation of the connecting ring 6. A baffle 20 is fixedly connected to the top, and the baffle 20 abuts against the side wall of the blade 5 close to the side of the surface cover 2. By rotating the rotary cover 9, the rotary cover 9 drives the connecting ring 6 to rotate, and the connecting ring 6 can drive the blade 5 to rotate. Because the two adjacent blades 5 are hooked with each other through the limit block 7 and the slide groove 8, when the top blade 5 rotates to abut against the limit block 7, the blade 5 continues to rotate, so that the bottom limit block 7 can also rotate together, and is transmitted to the blade 5 below in turn, until the top blade 5 abuts against the baffle 20, the closing of the through groove 3 can be completed.

[0026] A connecting rod 10 is fixedly connected to the connecting ring 6, and one end of the connecting rod 10 away from the connecting ring 6 is fixedly connected to a limiting plate 11. A groove 12 is provided on the inner wall of the rotary cover 9, and the limiting plate 11 is slidably connected in the groove 12. A clamping block 13 is fixedly connected to the bottom of the rotary cover 9, and a clamping slot 14 is provided on the top surface of the connecting ring 6.

[0027] A mounting ring 15 is fixedly connected to the base 1, and the outer wall of the rotary cover 9 is threadedly connected to the inner wall of the mounting ring 15. After the blade 5 is rotated to the desired position, the rotary cover 9 can be lifted and turned into the mounting ring 15, so as to fix the rotary cover 9 and prevent the blade 5 from moving due to accidental touching of the connecting ring 6 during daily placement. A handle 16 is rotatably connected to the top of the rotary cover 9, which can make it easier to rotate the rotary cover 9 and facilitate the adjustment of the rotary cover 9.

[0028] The seal includes a plurality of sealing strips 17, which are respectively fixedly connected to one side of each blade 5 close to the inner wall of the base 1. A receiving groove 18 for inserting the sealing strip 17 is opened on the inner wall of the base 1. During the rotation of the blade 5, the sealing strip 17 can always move in the receiving groove 18 to reduce the gap between the blade 5 and the base 1, thereby making the sealing effect of the through groove 3 better.

[0029] A dustproof net 19 is detachably connected to one side of the base 1 close to the surface cover 2. The wind generated by the fresh air system will pass through the through slot 3 and will also carry impurities such as dust in the air. These impurities can be intercepted by the dustproof net 19, and insects and other creatures can be prevented from flying into the base 1 and affecting the normal use of the fresh air system.

[0030] The base 1 , the cover 2 and the blades 5 are all made of ABS resin. ABS resin has the advantages of high strength and corrosion resistance, which ensures the service life of the base 1 , the cover 2 and the blades 5 .

[0031] The normal use of this utility model is as follows:

[0032] When it is necessary to adjust the air outlet size of the exhaust port, it is only necessary to rotate the rotary cover 9 through the handle 16, so that the rotary cover 9 drives the connecting ring 6 to rotate, and the connecting ring 6 can drive the blade 5 to rotate. Because the two adjacent blades 5 are hooked with each other through the limit block 7 and the slide groove 8, when the top blade 5 rotates to abut against the limit block 7, the blade 5 continues to be rotated, so that the bottom limit block 7 can also rotate together, and is transmitted to the blade 5 below in turn until the top blade 5 abuts against the baffle 20, and the through groove 3 can be closed. After the blade 5 is rotated to the desired position, the rotary cover 9 can be lifted and the rotary cover 9 can be turned into the mounting ring 15, so as to achieve the fixation of the rotary cover 9.

[0033] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
