Description

Technical Field

[0001] The utility model relates to the field of air valves, and in particular to an air valve control device with a feedback mechanism. Background Art

[0002] Air dampers, also known as dampers, are essential central air conditioning components for ventilation, air conditioning, and air purification systems. They are widely used in ventilation systems in industrial plants and residential buildings to regulate branch air volume and adjust the mixing of fresh and return air. Air dampers offer excellent airtightness, with relative air leakage typically around 5%, ensuring superior regulation performance.

[0003] The prior art with patent publication (announcement) number CN219841051U discloses a damper control device, including a damper housing, multiple blades, multiple vertical shafts and a transmission mechanism. The multiple blades are arranged in the damper housing and are evenly arranged. The multiple vertical shafts are respectively fixedly mounted on the front side walls of the corresponding blades. A plurality of vertical holes are opened at equal intervals on the top inner wall of the damper housing. The top ends of the multiple vertical shafts respectively pass through the corresponding vertical holes. The transmission mechanism is arranged on the top of the damper housing. The damper housing is used to control the rotation of the multiple blades.

[0004] The above patent document discloses a damper control device. Although it can solve the problem that most of the existing damper control devices are manually operated to adjust the air volume, and the dampers installed at high places need personnel to climb to a high place for manual adjustment during use, which is inconvenient to operate, the disadvantage is that when the motor of the damper control device is damaged during use, the damper cannot be adjusted in time, affecting its use.

[0005] Therefore, we make improvements to this and propose a damper control device with a feedback mechanism. Utility Model Content

[0033] To solve the technical problems in the background art, the following air valve control device with a feedback mechanism is provided:

[0034] Combine Figure 1 - Figure 5 As shown, the utility model provides a damper control device with a feedback mechanism, comprising a fixed frame 1, three blades 2 are arranged inside the fixed frame 1, and a fixed box 3 is fixedly installed on the upper surface of the fixed frame 1, a control mechanism 4 is arranged inside the fixed box 3, a sensor 5 is fixedly installed inside the fixed frame 1, a control center 6 and an effector 7 are fixedly installed inside the fixed box 3, and a manual emergency mechanism 8 is arranged on one side of the control mechanism 4 inside the fixed box 3.

[0035] In this embodiment: the air valve can be adjusted by rotating the three blades 2. The sensor 5 can detect parameters such as the temperature, humidity, air quality and the actual opening and closing degree of the air valve in the environment in real time. The sensor 5 will transmit the detected parameters to the control center 6. The control center 6 includes a data processing unit and a control strategy unit. The data processing unit receives the parameters transmitted by the sensor 5 and performs analysis and processing. The control strategy unit issues corresponding control instructions according to the preset control strategy. The effector 7 receives the instructions from the control center 6 and acts on the air valve body. The blades 2 are adjusted through the control mechanism 4, thereby realizing precise control of the air flow rate (this technology is an existing mature technology, so it is not described in detail).

[0036] refer to Figure 1 - Figure 3 On the basis of the above embodiment, the blade 2 can be driven to rotate. This embodiment provides the following design:

[0037] As a preferred embodiment, the control mechanism 4 includes a connecting rod 401, and there are three connecting rods 401. The three connecting rods 401 are respectively fixedly installed inside the three blades 2, and the three connecting rods 401 extend to the inside of the fixed box 3 respectively. The connecting rods 401 are rotatably connected inside the fixed frame 1.

[0038] In this embodiment, the connecting rods 401 are fixedly installed inside the blades 2 and are rotatably connected inside the fixed frame 1. The three connecting rods 401 can rotate to drive the blades 2 to rotate inside the fixed frame 1 to control the air volume.

[0039] As a preferred embodiment, a drive motor 403 is fixedly installed inside the fixed box 3, and the output end of the drive motor 403 is fixedly connected to a worm 404, and the other end of the worm 404 is fixedly connected to the fixed box 3, and a worm gear 402 is fixedly installed on the top of the three connecting rods 401, and the connection between the worm gear 402 and the worm 404 is a meshing connection.

[0040] In this embodiment, the worm gear 402 is meshed with the worm 404 . When the driving motor 403 drives the worm 404 at the output end to rotate, the three worm gears 402 can be driven to rotate at the same time, and the connecting rod 401 and the blade 2 can be driven to rotate.

[0041] refer to Figure 1 - Figure 5 On the basis of the above embodiment, the air valve can be adjusted in time when the motor is damaged. This embodiment provides the following design:

[0042] As a preferred embodiment, the manual emergency mechanism 8 includes a first gear 801, and the first gear 801 is fixedly mounted on the outer surface of the worm 404, a second gear 802 is provided on one side of the first gear 801, and the first gear 801 is meshed and connected with the second gear 802, and a rotating rod 803 is fixedly mounted inside the second gear 802, and a handle 804 is fixedly mounted on one end surface of the rotating rod 803.

[0043] In this embodiment: the first gear 801 is meshed with the second gear 802. When the handle 804 is rotated, the rotating rod 803 and the second gear 802 are driven to rotate, and then the first gear 801 and the worm 404 are driven to rotate. When the motor is damaged, the air valve is adjusted.

[0044] As a preferred embodiment, a fixed plate 805 is fixedly installed inside the fixed box 3, and a fixed rod 806 is connected to the bearing on one side surface of the fixed plate 805. A sliding groove 807 is provided inside the fixed rod 806, and the rotating rod 803 is slidably connected inside the sliding groove 807. Limiting strips 808 are fixedly installed on the upper and lower surfaces inside the sliding groove 807, and limiting grooves 809 are provided on the upper and lower sides of the outer surface of the rotating rod 803, and the limiting strip 808 is slidably connected to the limiting groove 809.

[0045] In this embodiment: the rotating rod 803 is slidably connected in the sliding groove 807, and the fixed rod 806 is bearing-connected to the fixed plate 805, so that the other end of the rotating rod 803 can be limited by the fixed rod 806, and the limiting bar 808 is slidably connected to the limiting groove 809, so that the rotating rod 803 can be limited, so that when the rotating rod 803 rotates, it drives the fixed rod 806 to rotate.

[0046] As a preferred embodiment, a groove 810 is formed on the surface of the slide slot 807 , and a spring 811 is fixedly mounted between the inner wall of the groove 810 and one end surface of the rotating rod 803 .

[0047] In this embodiment: by providing a spring 811, when the manual emergency mechanism 8 is not in use, the spring 811 can push the rotating rod 803 outward by itself, so that the second gear 802 on the surface does not engage with the first gear 801, thereby avoiding affecting the driving motor 403 to drive the worm 404 and the first gear 801 to rotate.

[0048] Specifically, the working principle of this solution is:

[0049] When in use, the sensor 5 will transmit the detected parameters to the control center 6. The control center 6 will receive the parameters transmitted by the sensor 5, analyze and process them, and issue corresponding control instructions. The instructions of the control center 6 will be received through the effector 7, act on the air valve body, and adjust the blades 2 through the control mechanism 4, so as to achieve precise control of the air flow rate. When the drive motor 403 is started to drive the worm 404 at the output end to rotate, it can drive the three worm gears 402 to rotate at the same time, and drive the connecting rod 401 and the blades 2 to rotate.

[0050] When the control mechanism 4 of the air valve is damaged, the handle 804 can be pressed toward the inside of the fixed box 3, and the rotating rod 803 and the second gear 802 on the surface can be driven to move, so that the second gear 802 is engaged with the first gear 801. The handle 804 can be turned to drive the rotating rod 803 and the second gear 802 to rotate, while driving the first gear 801 and the worm 404 to rotate, and drive the worm wheel 402 and the connecting rod 401 to rotate, so that the blade 2 rotates and the air valve is adjusted. The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0051] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
