[0029] See also Figure 1 and Figure 2 The regulating air valve structure of the embodiment of the present application includes a mounting plate 2, a wind shield plate 5, a push rod 4 and a driving device 1.

[0030] like Figure 2 and Figure 3 As shown, the windshield 5 is arranged on the mounting plate 2, and the mounting plate 2 is also provided with an air outlet 21. One end of the push rod 4 is fixedly connected to the windshield 5, and the other end is drivingly connected to the driving device 1. The driving device 1 is used to push the push rod 4 to reciprocate to adjust the shielding area of ​​the windshield 5 on the air outlet 21. Specifically, the driving device 1 can be a device for driving, such as a lead screw, a linear module, etc. This embodiment is described by taking a lead screw as an example. Figure 3 and Figure 4 As shown, the driving device 1 of this embodiment includes a housing 11 and a screw rod 14, a nut 15 and a nut stopper 16 arranged in the housing 11, and also includes a screw rod support 17. The screw rod 14 is installed on the screw rod support 17, and the screw rod 14 is provided with an external thread adapted to the nut 15. After the screw rod 14 is installed on the screw rod support 17, it can be rotated, wherein it can be driven to rotate by a motor, or by setting a knob assembly 13. In this embodiment, the knob assembly 13 is preferably set, so that the screw rod 14 can be driven to rotate by manually rotating the knob assembly 13; the nut stopper 16 limits the nut 15. When the screw rod 14 rotates, since the screw rod 14 is provided with an external thread and the nut stopper 16 limits the nut to only perform linear motion, the screw rod 14 can push the nut 15 to reciprocate linearly when it rotates, and the nut 15 is fixedly connected to the push rod 4, so the push rod 4 can be driven to reciprocate. The outer shell 11 covers the screw rod 14 and the nut 15 inside, which can play a role in installing and fixing the screw rod 14 and the nut 15, and can also prevent external dust and other impurities from falling on the screw rod 14, causing the screw rod 14 and the nut 15 to fit unsmoothly. At the same time, it can also prevent impurities from falling to the air outlet when the screw rod 14 and the nut 15 fit together and affecting the purity of the air outlet.

[0031] The mounting plate 2 includes a bottom plate 23 and a side plate 24. The screw support member 17 includes a first support member 171 and a second support member 172. The housing 11 is fixed on the bottom plate 23. The first support member 171, the nut 15 and the nut stopper 16 are fixed in the housing 11. The second support member 172 is fixed on the side plate 24. The first support member 171 and the second support member 172 are respectively located at opposite ends of the housing 11, and are used to support the screw 14 at both ends, respectively, and enable the screw 14 to rotate relative to the housing 11. The side plate 24 is vertically arranged with the bottom plate 23. A through hole is also provided on the side wall of the housing 11 close to the push rod 4. The position of the through hole corresponds to the push rod 4. In the present embodiment, one end of the push rod 4 is inserted into the housing 11 through the through hole, and is fixedly connected to the nut 15 on the screw rod 14. For example, the push rod 4 and the nut 15 are fixed by a threaded connection. Figure 5 As shown, the nut 15 of this embodiment includes a nut body 151 and a guide portion 152 disposed below the nut body 151. The bottom end of the guide portion 152 is provided with an arc surface, and the end of the guide portion 152 close to the push rod 4 is threadedly connected to the push rod 4. Figure 4 As shown, the nut stopper 16 is arranged in the housing 11, below the nut 15. The nut stopper 16 of this embodiment is an arc groove adapted to the bottom of the guide portion 152, and the arc surface at the bottom of the guide portion 152 is completely or partially located in the arc groove. When the screw rod 14 rotates, the nut 15 is restricted by the push rod 4 and the nut stopper 16, and performs linear reciprocating motion along the screw rod 14 and the nut stopper 16. The nut stopper 16 and the push rod 4 work together to prevent the nut 15 from being deflected during the movement and causing the nut 15 to get stuck. The nut stopper 16 is arranged directly below the screw rod 14 and is arranged parallel to the screw rod 14.

[0032] like Figure 2 and Figure 3 As shown, in order to make the push rod 4 move smoothly, a push rod cylinder sleeve 12 can also be installed on the outer shell 11. The push rod cylinder sleeve 12 of this embodiment is cylindrical and is arranged around the through hole of the outer shell 11. The inner diameter of the push rod cylinder sleeve 12 is matched with the outer diameter of the push rod 4. The push rod 4 is inserted into the outer shell 11 by the push rod cylinder sleeve 12 and connected with the nut 15. When the screw rod 14 rotates, the nut 15 performs reciprocating linear motion along the screw rod 14, and at the same time, drives the push rod 4 to perform reciprocating direct motion along the push rod cylinder sleeve 12, and the push rod 4 drives the windshield 5 fixedly connected thereto to move together. In order to prevent external air from entering the device from the driving device 1 and mixing with the air in the air outlet 21 to affect the temperature and quality of the gas, a sealing member 6 can be provided between the push rod cylinder sleeve 12 and the push rod 4, and the end of the push rod cylinder sleeve 12 away from the outer shell 11 can be extended to above the windshield 5. As shown Figure 4 and Figure 6As shown, in this embodiment, two sealing grooves 41 are provided at intervals along the radial direction on the outer surface of the push rod 4, and a sealing member 6 is sleeved in each sealing groove 41, and the sealing member 6 can be, for example, a silicone sealing ring. The sealing groove 41 is provided in the middle of the push rod 4. When the nut 15 moves along the screw rod 14 to the end portion close to one side of the push rod 4, the sealing groove 41 of the push rod 4 is approximately located near the outer end portion of the push rod cylinder sleeve 12, that is, the sealing ring can always maintain a sealing state with the push rod cylinder sleeve 12 during movement.

[0033] like Figures 2 to 4 As shown, in order to facilitate the rotation adjustment of the screw rod 14, a knob assembly 13 can also be installed at the end of the screw rod 14. For example, a round pancake-shaped connecting disk 132 can be threadedly connected to the end of the screw rod 14 away from the push rod 4, and a rocker 131 is offset on the outer surface of the connecting disk 132, and the rocker 131 is pushed to drive the screw rod 14 to rotate.

[0034] The side plate 24 is provided with a mounting hole 241 and a cover plate 242, and one end of the screw rod 14 passes through the mounting hole 241 on the side plate 24 and is connected to the knob assembly 13. The cover plate 242 is covered on the mounting hole 241. The mounting hole 241 can facilitate the installation of the screw rod 14, and the cover plate 242 can maintain the sealing of the side plate 24. The regulating air valve structure of this embodiment can also include an air outlet 22, which is connected to the air outlet hole 21 to guide the wind at the air outlet hole 21 to the outside. The air outlet 22 and the wind shield 5 are respectively arranged on the opposite side surfaces of the bottom plate 23.

[0035] The end of the push rod 4 away from the driving device 1 is fixedly connected to the wind shield 5 through the push rod mounting member 7, and the push rod mounting member 7 is fixedly connected to the end of the push rod 4 away from the driving device 1 and the end of the wind shield 5 away from the driving device 1. When the nut 15 moves linearly along the screw rod 14, it drives the push rod 4 and the wind shield 5 to move toward the end close to the driving device 1 or the end away from the driving device 1. When the nut 15 moves to the end of the screw rod 14 close to one end of the push rod 4, the air outlet 21 is located between the wind shield 5 and the driving device 1, that is, at this time, the wind shield 5 has no shielding on the air outlet 21, and the air outlet area of ​​the air outlet 21 is the largest. When the nut 15 moves to the side away from the push rod 4, the wind shield 5 slowly approaches and shields the air outlet 21. As the shielding area changes, the purpose of adjusting the size of the air outlet area of ​​the air outlet 21 is achieved. When the nut 15 moves to the end of the screw rod 14 away from one end of the push rod 4, the wind shield plate 5 completely covers the air outlet 21. At this time, the air outlet 21 is completely closed.

[0036] In order to make the windshield 5 more stable and reliable when moving and avoid deflection, a windshield guide groove 3 can also be provided to guide the moving direction of the windshield 5. The windshield guide groove 3 is provided on the surface of the mounting plate 2 facing away from the air outlet 22, and the windshield 5 is at least partially located in the windshield guide groove 3. The windshield guide groove 3 is fixed on the surface of the mounting plate 2, and the groove width of the windshield guide groove 3 matches the width of the windshield 5. Figure 3 As shown, the windshield guide groove 3 can be an integrated structure, for example, the windshield guide groove 3 is an integral plate-shaped structure, a groove for guiding and a through hole for avoiding the air outlet 21 are provided on the upper surface of the windshield guide groove 3, and the windshield guide groove 3 is arranged on the surface of the mounting plate 2 at the air outlet 21. The windshield guide groove 3 can also be a split structure, for example, the windshield guide groove 3 includes two strip plates, the two strip plates are respectively arranged on the mounting plate 2 on both sides of the air outlet 21, and the inner sides of the two strip plates and the upper surface of the mounting plate 2 together form a groove structure for guiding. Alternatively, the windshield guide groove 3 can also be formed by machining the upper surface of the mounting plate 2 inward, and machining a groove structure for guiding on the mounting plate 2 near the air outlet 21.

[0037] The embodiment of the present application also provides an environmental control device, including the above-mentioned regulating air valve structure, the mounting plate 2 is a partial shell of the environmental control device, that is, the air outlet 21 can be used as the air outlet of the environmental control device, and each environmental control device can be provided with multiple regulating air valve structures, so that the air volume of the environmental control device can be adjusted by the regulating air valve structure of this embodiment. Among them, the environmental control device can be, for example, a temperature control device.

[0038] The regulating air valve structure and environmental control equipment provided in the embodiments of the present application have a simple and compact overall structure, which reduces the installation space of the regulating air valve structure, improves the sealing effect, and improves the cleanliness of the air outlet.
