The worm gear mechanism is used to transmit the rotation of the handle to the wind shield. Since the worm gear has a self-locking function, it can prevent the wind shield from flipping over by itself, and avoid the fluctuation and reduction in the adjustment value of the air volume regulating valve caused by this. Furthermore, since reinforcing ribs are provided on the wind shield, the strength of the wind shield is improved, which reduces the deformation amount caused by the airflow and improves the accuracy of the air volume regulating valve.

[0004] However, in the above-mentioned prior art patent, no filtering device is provided in the regulating valve, and dust in the air can easily enter the regulating valve, causing dust to flow into the room along with the cold wind, thus affecting the indoor air quality. Utility Model Content

[0024] The utility model provides a regulating valve: including a driving module 101, a valve housing 102, a windshield 103 and a dustproof component, the dustproof component includes a dustproof net 104, multiple sets of support members, two limit arc blocks 105, two resisting springs 114, two pull blocks 106, two slide bars 107 and two rubber pads 108, and the support member includes a fixing plate 109, a support rod 110 and rubber convex particles 111. The above-mentioned solution solves the problem that the existing regulating valve is not provided with a filtering device, and dust in the air easily enters the regulating valve, which will cause dust to be blown into the room with the cold wind, affecting the indoor air quality.

[0025] With respect to this specific embodiment, the wind shield 103 is movably connected to the valve housing 102 and is located inside the valve housing 102. The driving module 101 is arranged on the outer wall of the valve housing 102, and the output end of the driving module 101 is connected to the wind shield 103. The driving module 101 includes a turntable, a connecting rod and a worm gear mechanism. When a person turns the turntable, the turntable drives the connecting rod to rotate. The rotation of the turntable is transmitted to the wind shield 103 by using the worm gear mechanism. Since the worm gear has a self-locking function, it can prevent the wind shield 103 from flipping over by itself, and avoid the fluctuation and reduction in accuracy of the adjustment value of the air volume control valve caused by this. The driving module 101 is already a prior art and will not be elaborated on here.

[0026] Among them, multiple groups of the support members are fixedly connected to the valve housing 102 and are located on the inner side wall of the valve housing 102. The valve housing 102 has two limit grooves 112 and two receiving grooves 113. The two limit arc blocks 105 are movably connected to the valve housing 102 and are respectively located in the corresponding limit grooves 112. The two slide bars 107 are fixedly connected to the corresponding limit arc blocks 105 and respectively penetrate the corresponding limit grooves 112. Each of the resisting springs 114 is fixedly connected to the valve housing 102 and the corresponding limit arc blocks 105, and are respectively located in In the corresponding limiting groove 112, the two pull blocks 106 are respectively fixedly connected to the corresponding sliding rods 107 and are respectively located in the receiving grooves 113. The dustproof net 104 is arranged in the valve housing 102. The dust in the air is filtered by the dustproof net 104 in the valve housing 102. When the dustproof net 104 is installed in the valve housing 102, the dustproof net 104 is moved into the valve housing 102, and the two limiting arc blocks 105 are squeezed under the dustproof net 104. Each limiting arc block 105 is squeezed to enter the valve housing 1 02, and at the same time, the limiting arc block 105 will squeeze the holding spring 114 until the dustproof net 104 contacts with multiple groups of the supporting parts, and the multiple groups of the supporting parts limit the support of the dustproof net 104. At this time, the two limiting arc blocks 105 are no longer squeezed by the dustproof net 104, and each of the holding springs 114 will stretch in the limiting groove 112 and push the limiting arc block 105 to move out of the limiting groove 112. The two limiting arc blocks 105 cooperate with multiple groups of the supporting parts to fix the dustproof net 104 in the valve housing 102, thereby The dustproof net 104 is installed in the valve housing 102. When the dustproof net 104 is removed, the pull blocks 106 can be pulled respectively in the two receiving grooves 113 on the outside of the valve housing 102. Each pull block 106 drives the slide bar 107 to move in the limiting groove 112. At the same time, the slide bar 107 will separate the limiting arc block 105 from the dustproof net 104. Then the personnel will take the dustproof net 104 out of the valve housing 102. Through the above method, it is possible to filter the dust in the air in the regulating valve to prevent dust from entering the room and affecting the air quality.

[0027] Secondly, the two rubber pads 108 are fixedly connected to the corresponding limiting arc blocks 105 and are respectively located on the outer side walls of the limiting arc blocks 105. By arranging the rubber pads 108 on the outer side of the limiting arc blocks 105, the rubber pads 108 can increase the friction between the limiting arc blocks 105 and the dustproof net 104, and can fix the dustproof net 104 more stably in the valve housing 102.

[0028] At the same time, the fixing plate 109 is fixedly connected to the valve housing 102 and is located on the inner wall of the valve housing 102, the support rod 110 is fixedly connected to the fixing plate 109 and is located above the fixing plate 109, the rubber protrusion 111 is fixedly connected to the support rod 110 and is located at the end of the support rod 110 away from the fixing plate 109, the fixing plate 109 fixes the support rod 110 on the inner wall of the valve housing 102, and the support rod 110 is provided with the rubber protrusion 111. When the dustproof net 104 is fixed in the valve housing 102, the support rod 110 provides limited support for the dustproof net 104 in the valve housing 102, and the rubber protrusion 111 will be compressed. The rubber protrusion 111 can improve the stability of the dustproof net 104 in the valve housing 102.

[0029] The dustproof net 104 is used to filter dust in the air in the valve housing 102. When the dustproof net 104 is installed in the valve housing 102, the dustproof net 104 is moved into the valve housing 102, and the two limiting arc blocks 105 are squeezed under the dustproof net 104. Each limiting arc block 105 is squeezed to enter the limiting groove 112 of the valve housing 102. At the same time, the limiting arc block 105 squeezes the holding spring 114 until the dustproof net 104 contacts the rubber convex particles 111, and the plurality of support rods 110 limit and support the dustproof net 104. At this time, the two limiting arc blocks 105 are no longer squeezed by the dustproof net 104, and each holding spring 114 is stretched in the limiting groove 112 and pushes the The limiting arc block 105 moves out from the limiting groove 112, and the two limiting arc blocks 105 cooperate with the multiple supporting rods 110 to fix the dustproof net 104 in the valve housing 102, so that the dustproof net 104 is installed in the valve housing 102. When the dustproof net 104 is disassembled, the pull blocks 106 can be pulled in the two storage grooves 113 on the outside of the valve housing 102 respectively, and each of the pull blocks 106 drives the sliding rod 107 to move in the limiting groove 112 respectively. At the same time, the sliding rod 107 will separate the limiting arc block 105 from the dustproof net 104, and then the personnel will take the dustproof net 104 out of the valve housing 102. Through the above method, it is achieved that the dust in the air can be filtered in the regulating valve to prevent dust from entering the room and affecting the air quality.

When the dustproof net 104 is taken out from the valve housing 102, the two pull blocks 106 are pulled respectively to drive the two limit arc blocks 105 to separate from the dustproof net 104. At this time, the two spring rods will be stretched in the movable groove 205 of the housing respectively, and the spring rod will push the movable rod 201 to move upward. The movable rod 201 will push the dustproof net 104 from the valve housing 102 to the outlet, and then the dustproof net 104 will be taken out for replacement.

At this time, the return spring 204 in each outer cylinder 203 will be stretched, and the return spring 204 will drive the inner rod 202 to move outward in the outer cylinder 203. Then the movable rod 201 pushes the dustproof net 104 out of the valve housing 102, and the dustproof net 104 is pushed to the outlet of the valve housing 102. Then the dustproof net 104 is taken out for replacement. Through the above method, the dustproof net 104 can be easily moved out, which is convenient for the staff to replace the dustproof net 104.
