DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] Embodiment one, please refer to Figures 1-6 , the valve control assembly and the air valve, including the outer frame of the air valve 1, the valve core assembly 2 is hinged in the outer frame of the air valve 1, the regulating assembly 3 for controlling the valve core assembly 2 is installed at the top of the outer frame of the air valve 1, the filtering assembly 4 is also arranged at the air inlet end of the outer frame of the air valve 1, the filtering assembly 4 is slidingly connected in the outer frame of the air valve 1, the shielding assembly 5 for shielding the filtering assembly 4 is also arranged at the end of the outer frame of the air valve 1 close to the filtering assembly 4, the valve core assembly 2 includes the first wind baffle 21 and the second wind baffle 22, the connecting rod 23 is installed at one side of the first wind baffle 21 and the second wind baffle 22, the connecting frame 11 is installed in the inner wall of the outer frame of the air valve 1, the two ends of the two connecting rods 23 are rotatably connected to the top and bottom of the connecting frame 11 respectively, and the top of the two connecting rods 23 penetrates through the top of the outer frame of the air valve 1 and is connected with the regulating assembly 3 at the top of the outer frame of the air valve 1, the synchronous shaft 25 is fixedly connected to the top of the two connecting rods 23, the synchronous belt 26 is arranged between the two synchronous shafts 25, the two synchronous shafts 25 are drivingly connected through the synchronous belt 26, and the sealing gasket 24 is also installed at the sidewall of the first wind baffle 21 and the second wind baffle 22;

[0029] When it is needed to use, first, the shielding assembly 5 is started to make the shielding assembly 5 close the filtering assembly 4, the air is temporarily blocked through the filtering assembly 4 and the shielding assembly 5, at the same time, the regulating assembly 3 is started to make the regulating assembly 3 drive the first wind baffle 21 and the second wind baffle 22 to overturn, so that the first wind baffle 21 and the second wind baffle 22 are opened, after being opened, the shielding assembly 5 is adjusted to make the filtering assembly 4 open, so that the air can pass through the filtering assembly 4 and the outer frame of the air valve 1;

[0030] By setting the synchronous shaft 25 and the synchronous belt 26 on the two connecting rods 23, in use, by controlling the rotation of one of the synchronous shafts 25, the other synchronous shaft 25 can be driven to rotate through the synchronous belt 26, so that the first wind deflector 21 and the second wind deflector 22 can be adjusted synchronously. At the same time, by setting the sealing gaskets 24 on the first wind deflector 21 and the second wind deflector 22, when the valve is closed, the first wind deflector 21 and the second wind deflector 22 can be tightly fitted with the inner wall of the valve frame 1 through the multiple sealing gaskets 24, improving the overall sealing performance and avoiding air leakage.

[0031] By setting the filter assembly 4 and the shielding assembly 5, in use, the larger impurities in the external air can be filtered by the filter assembly 4 to avoid blocking the inside of the valve. When the air is adjusted, the shielding assembly 5 can temporarily block the air by closing the filter assembly 4, which can reduce the air pressure inside the valve frame 1, making it easier and more accurate to turn over the first wind deflector 21 and the second wind deflector 22.

[0032] Example two, please refer to Figures 1-4 The control assembly 3 includes a control box 31, a drive motor 32 is fixedly connected in the control box 31, the output end of the drive motor 32 is fixedly connected with one of the synchronous shafts 25 through a shaft coupling, and a one-way bearing is arranged between the output shaft of the drive motor 32 and the adjacent synchronous shaft 25. A first bevel gear 33 is also arranged in the control box 31, the first bevel gear 33 is rotatably connected in the control box 31, and the bottom of the first bevel gear 33 is fixedly connected with the other synchronous shaft 25. A second bevel gear 34 is also engaged with the first bevel gear 33, the second bevel gear 34 is fixedly connected with a synchronous rod 35 on the side away from the first bevel gear 33, and the end of the synchronous rod 35 away from the second bevel gear 34 penetrates through the side wall of the control box 31 and extends to the outside of the control box 31. A rotating disc 36 is fixedly connected with the extending end of the synchronous rod 35, a rotating handle 37 is fixedly connected with the side of the rotating disc 36 away from the control box 31, and a limiting plug rod 39 is slidably connected with the rotating disc 36. A plurality of limiting holes 38 adapted to the limiting plug rod 39 are formed in the side of the control box 31 close to the limiting plug rod 39, and the limiting plug rod 39 is slidably inserted into the adjacent limiting hole 38.

[0033] In use, when the valve needs to be opened, the drive motor 32 in the control box 31 is first started to drive the synchronous shaft 25 to rotate, which drives the adjacent connecting rod 23 to rotate. When one of the synchronous shafts 25 rotates, the other synchronous shaft 25 can be driven to rotate synchronously through the synchronous belt 26, so that the two connecting rods 23 rotate simultaneously, thereby driving the first wind deflector 21 and the second wind deflector 22 to turn over, and the valve is opened.

[0034] Meanwhile, when adjusting manually, first pull the limiting rod 39 on the rotating disk 36 out of the limiting hole 38 to release the limitation on the rotating disk 36. Rotate the rotating disk 36 by rotating the handle 37, so that the rotating disk 36 drives the synchronous rod 35 to rotate. The synchronous rod 35 drives the second bevel gear 34 to rotate, so that the first bevel gear 33 meshing with the second bevel gear 34 rotates synchronously. The first bevel gear 33 drives the adjacent synchronous shaft 25 to rotate. The synchronous shaft 25 drives another synchronous shaft 25 to rotate through the synchronous belt 26, so that the two connecting rods 23 rotate, thereby causing the first wind deflector 21 and the second wind deflector 22 to flip, so that the valve opens or closes.

[0035] After adjustment, pass the limiting rod 39 through the rotating disk 36 and insert it into the adjacent limiting hole 38. The limiting rod 39 fixes the rotating disk 36 to prevent it from rotating on its own.

[0036] Example 3, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The filter assembly 4 includes a filter plate 41, which is slidably snapped into the outer frame 1 of the air valve. The filter plate 41 has multiple evenly distributed filter grooves 42. The shielding assembly 5 includes a shielding frame 51, which is slidably disposed on one side of the filter plate 41 and in contact with the filter plate 41. A shielding plate 52 of the same size as the multiple filter grooves 42 is installed on the shielding frame 51. An electric push rod 54 is also provided on the top of the shielding frame 51 and is installed in the inner wall of the top of the outer frame 1 of the air valve. A connecting block 53 is installed on the top of the shielding frame 51 and the output end of the electric push rod 54 is fixed to the connecting block 53.

[0037] Before ventilation, first start the electric push rod 54, so that the electric push rod 54 pushes the connecting block 53 to slide inside the outer frame 1 of the air valve. The connecting block 53 drives the shielding frame 51 and the shielding plate 52 to slide, so that the shielding plate 52 blocks the filter tank 42 and temporarily blocks the air blown from the air inlet. At the same time, start the drive motor 32 in the control box 31 to quickly adjust the first baffle 21 and the second baffle 22.

[0038] After adjustment, turn off the electric push rod 54, so that the electric push rod 54 drives the connecting block 53 to reset, so that the baffle plate 52 separates from the filter tank 42, so that the air enters the outer frame 1 of the air valve through the filter tank 42 and continues to flow through the first baffle 21 and the second baffle 22.

[0039] With the filter assembly 4 and the shielding assembly 5 in use, larger impurities in the outside air can be filtered through the filter plate 41 and the filter groove 42. When the air is inlet, the shielding frame 51 and the shielding plate 52 are adjusted by activating the electric push rod 54 to seal the filter groove 42 and temporarily block the airflow. This can reduce the air pressure inside the outer frame 1 of the air valve, making it easier to rotate the first baffle 21 and the second baffle 22.

[0040] Example 4, please refer to Figures 1-6 This includes the aforementioned valve control components;

[0041] With the valve control component, the first and second wind vanes 21 and 22 can be quickly adjusted via the manual and automatic adjustment mechanisms in the control box 31. Simultaneously, the filter assembly 4 and the shielding assembly 5 filter larger impurities in the air through the filter plate 41 and filter groove 42, preventing impurities from entering the outer frame 1 of the air valve and causing blockage. During air intake, the electric push rod 54 is activated to adjust the shielding frame 51 and shielding plate 52 to temporarily block the airflow by closing the filter groove 42, reducing the air pressure inside the outer frame 1 of the air valve and making the rotation of the first and second wind vanes 21 and 22 easier.

[0042] Working principle: Before ventilation, the electric push rod 54 is activated first, which pushes the connecting block 53 to slide inside the outer frame 1 of the air valve. The connecting block 53 drives the shielding frame 51 and the shielding plate 52 to slide, so that the shielding plate 52 blocks the filter tank 42 and temporarily blocks the air blown from the air inlet.

[0043] Start the drive motor 32 in the control box 31, so that the drive motor 32 drives the synchronous shaft 25 to rotate. The synchronous shaft 25 drives the adjacent connecting rod 23 to rotate. When one synchronous shaft 25 rotates, the synchronous belt 26 can drive the other synchronous shaft 25 to rotate synchronously, so that the two connecting rods 23 rotate at the same time. This causes the two connecting rods 23 to drive the first wind deflector 21 and the second wind deflector 22 to flip, so that the valve opens.

[0044] Meanwhile, when adjusting manually, first pull the limit rod 39 out of the limit hole 38, rotate the rotating disk 36 by rotating the handle 37, so that the rotating disk 36 drives the synchronous rod 35 to rotate, and the synchronous rod 35 drives the second bevel gear 34 to rotate, so that the first bevel gear 33 rotates synchronously, and the first bevel gear 33 drives the adjacent synchronous shaft 25 to rotate, and the synchronous shaft 25 drives the other synchronous shaft 25 to rotate through the synchronous belt 26, so that the two connecting rods 23 rotate, thereby causing the first wind deflector 21 and the second wind deflector 22 to flip, so that the valve opens. After adjustment, pass the limit rod 39 through the rotating disk 36 and insert it into the adjacent limit hole 38, so that the rotating disk 36 is fixed by the limit rod 39 to prevent the rotating disk 36 from rotating on its own.

[0045] After adjustment, turn off the electric push rod 54, so that the electric push rod 54 drives the connecting block 53 to reset, so that the baffle plate 52 separates from the filter tank 42, so that the air enters the outer frame 1 of the air valve through the filter tank 42 and continues to flow through the first baffle 21 and the second baffle 22.

[0046] During use, the manual and automatic adjustment structures set in the control box 31 can quickly adjust the first baffle 21 and the second baffle 22 to open or close the valve. At the same time, through the filter assembly 4 and the shielding assembly 5, larger impurities in the air can be filtered through the filter plate 41 and the filter groove 42 during use, preventing impurities from entering the outer frame 1 of the air valve and causing blockage. When air is introduced, the electric push rod 54 is activated to adjust the shielding frame 51 and the shielding plate 52 to seal the filter groove 42 and temporarily block the airflow, making the rotation of the first baffle 21 and the second baffle 22 more effortless and precise.
