The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present invention provides a constant air volume regulating device for an air valve. Figure 1-4 As shown, it includes a valve body 1, a drive motor 2 is installed at the top of the valve body 1, and a plurality of parallel and distributed rotating rods 5 are rotatably connected inside the valve body 1. The output shaft end of the drive motor 2 is connected to the end of one of the rotating rods 5, and the drive motor 2 is used to drive the rotating rod 5 to rotate. A dustproof mechanism 3 is installed inside the valve body 1, and the dustproof mechanism 3 is used to block dust in the air circulation;

[0023] The dustproof mechanism 3 includes a dustproof net 301 and strip holes 302;

[0024] The dust screen 301 has a plurality of equally spaced filter holes formed therein. The dust screen 301 is used to filter dust so that the dust adheres to its surface. The strip holes 302 are formed inside the valve body 1. The strip holes 302 allow the dust screen 301 to slide axially from the inside of the valve body 1 to the outside thereof. The dust screen 301 that slides axially to the outside of the valve body 1 is easily cleaned.

[0025] The dustproof mechanism 3 further includes a slide groove 303, a slider 304, a buckle 305, and a slot 306;

[0026] There are two chutes 303 , which are respectively provided at the top and bottom ends of the inner side of the strip-shaped hole 302 . The slider 304 is slidably connected to the inside of the chutes 303 , and the end of the slider 304 is fixedly connected to the end of the dustproof net 301 .

[0027] There are multiple clips 305, which are fixedly connected to the ends of the slider 304 through a connecting piece, and two clips 305 are symmetrically distributed at both ends of the slider 304. The slots 306 are opened inside the slide 303, and there are two symmetrical slots 306 inside the slide 303. The clips 305 and the slots 306 are engaged with each other. The engaged clips 305 and the slots 306 are used to lock and fix the position of the dustproof net 301.

[0028] The outer wall of the rotating rod 5 is fixedly connected to the blade 4, and the rotating rod 5 is used to drive the blade 4 to rotate. The number of the blade 4 is multiple. The blade 4 in the inclined state makes the interior of the valve body 1 open to facilitate air circulation, and the blade 4 in the horizontal state makes the interior of the valve body 1 closed.

[0029] The bottom end of the blade 4 is fixedly connected to a connecting frame 6, and one end of the connecting frame 6 is rotatably connected to a moving frame 7 via a connecting shaft.

[0030] In this embodiment, the driving motor 2 is used to drive the rotating rod 5 to rotate, and the rotating rod 5 drives the blades 4 to rotate. The rotation amplitude of the blades 4 is adjusted according to the amount of air that needs to be adjusted (it should be noted that the larger the rotation amplitude of the blade 4, the larger the opening inside the valve body 1, and thus the greater the air intake, and the smaller the rotation amplitude of the blade 4, the smaller the opening inside the valve body 1, and thus the smaller the air intake). The rotating rod 5 drives one of the blades 4 to rotate, so that the blade 4 drives the moving frame 7 to move through the connecting frame 6, so that the moving frame 7 assists the three blades 4 to move synchronously. The three blades 4 adjust their rotation positions so that the airflow flows to the designated area through the opening formed by the three blades 4 and the inner side of the valve body 1;

[0031] During the airflow, the air will pass through the dustproof net 301, and the impurities and dust in the air will adhere to the dustproof net 301, so that clean air will circulate to the designated area. After long-term use, the dustproof net 301 will accumulate too much dust and needs to be cleaned. The dustproof net 301 is pulled out from the inside of the valve body 1 through the strip hole 302 by holding the handle. The slider 304 slides axially along the track of the slide groove 303, thereby assisting the axial movement of the dustproof net 301, and a buckle 305 is separated from a slot 306, and the dustproof net 301 is pulled out.

[0032] When the dust screen 301 slides to a certain position during the extraction process, the other buckle 305 contacts and engages with the other slot 306. At this time, the extracted position of the dust screen 301 is locked, and the dust screen 301 will not be completely separated from the valve body 1. The dust screen 301 is more stable, thereby cleaning the dust screen 301.

[0033] The cleaned dustproof net 301 is then slid axially into the interior of the valve body 1 as described above, so that another buckle 305 is separated from another slot 306, and one buckle 305 contacts and engages with one slot 306, so that the position of the dustproof net 301 is locked and fixed, thereby achieving the effect of blocking dust in the air and preventing dust from adhering to the blade 4.

[0034] In a further preferred embodiment of the present invention, Figure 3 As shown, the outer wall of the slider 304 and the inner wall of the slide groove 303 are matched with each other, and the buckle 305 is an elastic structure.

[0035] In this embodiment, the slider 304 slides axially along the track of the slide groove 303, thereby assisting the axial movement of the dustproof net 301, and the buckle 305 contacts and engages with the slot 306, so that the position of the dustproof net 301 is locked and fixed.

[0036] In a further preferred embodiment of the present invention, Figure 3 As shown, the end surface of the dustproof net 301 contacts the inner end surface of the valve body 1, and the end of the dustproof net 301 is provided with a handle for holding by hand.

[0037] In this embodiment, when the dust net 301 with excessive dust accumulation needs to be cleaned, the dust net 301 is pulled out from the inside of the valve body 1 through the strip hole 302 by holding the handle, thereby cleaning the dust net 301.

[0038] In a further preferred embodiment of the present invention, Figure 3 As shown, a sealing gasket is provided on the contact surface between the dustproof net 301 and the strip hole 302 , and the sealing gasket is used to prevent air leakage at the joint between the dustproof net 301 and the strip hole 302 .

[0039] In this embodiment, when the dustproof net 301 is pulled out from or slid into the valve body 1, the dustproof net 301 is squeezed when in contact with the valve body 1 by the sealing gasket, thereby improving the sealing performance and avoiding air leakage.
