DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a linked air valve exhaust device comprises a linked air valve body 1; the middle part of the linked air valve body 1 is rotatably connected to a plurality of rotating shafts 11; the middle part of the rotating shafts 11 is fixedly connected to guide vanes 12; the ends of the rotating shafts 11 are fixedly connected to telescopic rods 13; the ends of the telescopic rods 13 are fixedly connected to the side of the connecting plate 14; the end of the connecting plate 14 is fixedly connected to a steering plate 15; the middle part of the linked air valve body 1 is fixedly connected to a plurality of supporting plates 16; the middle part of the supporting plates 16 is slidably connected to pillars 17; the ends of the pillars 17 are fixedly connected to the middle of the steering plate 15; the middle part of the supporting plates 16 is fixedly connected to a first spring 18; the other end of the first spring 18 is fixedly connected to the end of the pillar 17; during operation, when the linked air valve body 1 is supplying air, the air flow inside it will flow out to the outside through the guide vanes 12, and when it is necessary to change the angle of the guide vanes 12, the pillars 17 can be pushed first, so as to make The support 17 drives the steering plate 15 to move forward and backward in the middle of the support plate 16. When the support 17 moves, the first spring 18 will be extended and retracted due to the pressure. At the same time, the movement of the steering plate 15 will drive the connecting plate 14 to move. At this time, the telescopic rod 13 is extended and retracted due to the influence of the connecting plate 14, and drives the rotating shaft 11 and the guide vane 12 to rotate in the middle of the linked air valve body 1, so as to change the angle of the guide vane 12. In this step, the wind delivered by the linked air valve body 1 can be guided by the guide vane 12, so that the air can pass through the air valve more smoothly, and then the air supply volume and pressure can be more accurately controlled, so as to prevent the direction of the airflow from changing when it flows out from the inside of the linked air valve body 1 and the airflow from becoming scattered. By pushing the support 17 to change the angle of the guide vane 12, it can be used to change the wind direction of the airflow, so that the airflow can be blown to the designated area more accurately.

[0025] like Figure 1 , Figure 3 , Figure 4As shown, both sides of the support plate 16 are fixed with arc plates 2; the middle of the pillar 17 is fixed with a clamping plate 21; the middle of the arc plate 2 is fixed with multiple sets of transverse shafts 22; the middle of the transverse shafts 22 are rotatably connected with clamping blocks 23; the middle of the clamping blocks 23 are fixed with multiple sets of second springs 24; the ends of the second springs 24 are fixed with transverse plates 25; both ends of the transverse plates 25 are fixed to the inner side wall of the arc plate 2; when working, when the pillar 17 is pushed, the clamping plate 21 will move with the movement of the pillar 17, and when the clamping plate 21 moves to a certain position, the clamping block 23 will be affected by the thrust of the clamping plate 21 and thus move with the help of the second spring 2 4 acts elastically on the middle part of the horizontal axis 22 to rotate. At this time, the support 17 is continuously pushed. The second spring 24 will drive the block 23 to reset due to the lack of thrust constraint, so that the block 23 can clamp the clamping plate 21. This step can assist in fixing the guide vane 12 after the angle adjustment of the guide vane 12 is completed through the mutual cooperation of the block 23 and the clamping plate 21, so as to prevent the guide vane 12 from being easily blown by the airflow inside the linkage air valve body 1 and rotating, so that its angle changes, and finally affects the guidance of the airflow, resulting in a lower accuracy of air supply to the designated area.

[0026] like Figure 4 As shown, the sides of the blocking block 23 are fixedly connected with the first hollow limiting disc 3; the middle part of the first hollow limiting disc 3 is fixedly connected with multiple groups of connecting columns 31; the ends of the connecting columns 31 are fixedly connected with the second hollow limiting disc 32; the sides of the second hollow limiting disc 32 are fixedly connected to the inner wall of the arc plate 2; when working, the connecting columns 31 play the role of connecting the first hollow limiting disc 3 and the second hollow limiting disc 32, and the movement trajectory of the blocking block 23 can be limited by the opening of the first hollow limiting disc 3 and the second hollow limiting disc 32. This step can prevent the blocking block 23 from shifting left and right during rotation through the mutual cooperation of the first hollow limiting disc 3 and the second hollow limiting disc 32, thereby causing the position of the blocking block 23 to deviate, affecting the blocking work of the blocking block 23 on the card plate 21.

[0027] like Figure 2 , Figure 5 As shown, a cross support frame 4 is fixedly connected to the middle part of the linkage air valve body 1; a connecting shaft 41 is fixedly connected to the middle part of the cross support frame 4; a plurality of groups of serrated blades 42 are rotatably connected to the middle part of the connecting shaft 41; during operation, when the linkage air valve body 1 is supplying air, the air flow inside it will first flow through the serrated blades 42, at which time the serrated blades 42 will rotate at the middle part of the connecting shaft 41 under the influence of the air flow, and this step is that when the air flow flows through the serrated blades 42, the serrated blades 42 will divide the large vortex of the air flow into small vortices, thereby reducing the vortex loss and vortex noise, thereby reducing the intensity of the noise generated when the linkage air valve body 1 supplies air, thereby achieving the effect of reducing noise pollution.

[0028] like Figure 2 , Figure 5 As shown, a vertical plate 5 is fixedly connected to the middle of the connecting shaft 41; a plurality of groups of brushes 51 are fixedly connected to the middle of the vertical plate 5; during operation, when the serrated blades 42 are rotated under the influence of the airflow, their surfaces will contact the brushes 51, so that the brushes 51 can clean the surfaces of the serrated blades 42. The purpose of this step is that when the gas flows, it will carry dust and impurities in the air together, which can easily make the serrated blades 42 contaminated with dust. Over a long period of time, the dust will become thicker and thicker, so that the surface of the connecting shaft 41 is corroded and the normal rotation of the serrated blades 42 is affected. At this time, the accumulation of dust on the serrated blades 42 can be reduced by opening the vertical plate 5 and the brushes 51.

[0029] like Figure 2 As shown, a sound insulation cotton 6 is fixedly connected to the middle part of the linkage air valve body 1; during operation, when the airflow flows inside the linkage air valve body 1, a certain noise will be generated, and the sound insulation cotton 6 can absorb part of the noise at this time. This step can further reduce the spread of noise and suppress noise pollution through the opening of the sound insulation cotton 6, thereby providing a relatively comfortable environment for the surrounding.

[0030] like Figure 1 As shown, a rubber ring 7 is connected to the end of the linkage air valve body 1; during operation, when the end of the linkage air valve body 1 is connected to the other end, the rubber ring 7 can reduce the gap at the connection. This step can prevent the gap of the connection port of the linkage air valve body 1 from being too large, thereby causing the air flow inside to be lost from the gap.

[0031] Working principle: during operation, when the linkage air valve body 1 is supplying air, the air flow inside it will flow out to the outside through the guide vane 12. When the angle of the guide vane 12 needs to be changed, the pillar 17 can be pushed first, so that the pillar 17 drives the steering plate 15 to move forward and backward in the middle of the support plate 16. When the pillar 17 moves, the first spring 18 will be extended and retracted under the influence of the pressure. At the same time, the movement of the steering plate 15 will drive the connecting plate 14 to move. At this time, the telescopic rod 13 is extended and retracted under the influence of the connecting plate 14, and drives the rotating shaft 11 and the guide vane 12 to rotate in the middle of the linkage air valve body 1, so as to change the angle of the guide vane 12. This step can adjust the linkage air valve body through the action of the guide vane 12. The wind sent out by the valve body 1 is guided, so that the air passes through the air valve more smoothly, and then the air supply volume and pressure are controlled more accurately, so as to prevent the airflow from changing direction and becoming scattered when it flows out from the inside of the linkage air valve body 1. By pushing the pillar 17 to change the angle of the guide blade 12, it can be used to change the wind direction of the airflow, so that the airflow can be blown to the designated area more accurately. When working, when the pillar 17 is pushed, the card plate 21 will move with the movement of the pillar 17. When the card plate 21 moves to a certain position, the card block 23 will be affected by the thrust of the card plate 21 and rotate at the middle part of the horizontal axis 22 with the elastic action of the second spring 24. At this time, the pillar 17 is continued to be pushed,The second spring 24 will drive the block 23 to reset due to the lack of thrust constraint, so that the block 23 can be clamped on the clamping plate 21. This step can assist in fixing the guide vane 12 after the angle adjustment of the guide vane 12 is completed through the cooperation between the block 23 and the clamping plate 21, so as to prevent the guide vane 12 from being easily blown by the airflow inside the linkage air valve body 1 and rotating, so that its angle changes, and finally affects the guidance of the airflow, resulting in a lower accuracy of air supply to the designated area. When working, the connecting column 31 connects the first hollow limit disc 3 and the second hollow limit disc 32, and through the first hollow limit disc 3 and the second hollow limiting disc 32 are opened to limit the moving track of the card block 23. This step can prevent the card block 23 from shifting left and right when it rotates, thereby causing the position of the card block 23 to deviate, affecting the card block 23 from blocking the card plate 21. When working, when the linkage air valve body 1 is supplying air, the air flow inside it will first flow through the serrated blades 42. At this time, the serrated blades 42 will rotate at the middle of the connecting shaft 41 under the influence of the air flow. This step is that when the air flow flows through the serrated blades 42, the serrated blades 42 will transfer the air The large vortex of the air flow is divided into small vortices, thereby reducing the loss and vortex noise of the vortex, thereby reducing the intensity of the noise generated by the linked air valve body 1 when delivering air, thereby achieving the effect of reducing noise pollution. During operation, when the serrated blades 42 are affected by the air flow and rotate, their surfaces will contact with the brush 51, so that the brush 51 can clean the surface of the serrated blades 42. This step is that when the gas flows, it will carry dust and impurities in the air together, so that the serrated blades 42 are easily contaminated with dust. After long-term accumulation, the dust will become thicker and thicker, so that the surface of the connecting shaft 41 is corroded and the normal rotation of the serrated blades 42 is affected. At this time, the dust will accumulate in the air and the serrated blades 42 will be affected. The opening of the vertical plate 5 and the brush 51 can reduce the accumulation of dust at the serrated blades 42. When working, when the airflow flows inside the linkage air valve body 1, a certain amount of noise will be generated. At this time, the sound insulation cotton 6 can absorb part of the noise. This step can further reduce the spread of noise and suppress noise pollution through the opening of the sound insulation cotton 6, thereby providing a relatively comfortable environment for the surrounding. When working, when the end of the linkage air valve body 1 is connected to the other end, the rubber ring 7 can reduce the gap at the connection. This step can prevent the gap of the linkage air valve body 1 connection port from being too large through the action of the rubber ring 7, thereby causing the airflow inside it to be lost from the gap.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
