[0031] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0032] Please see Figures 1 to 3 This utility model provides an air volume regulating valve, including a valve body 1, a valve plate 2, and an regulating component 3.

[0033] The valve plate 2 is detachably rotatably connected to the valve body 1, and the valve plate 2 can close the ventilation channel of the valve body 1. In this embodiment, the valve plate 2 is an EPP valve plate, and the valve plate 2 is rotatably connected to the valve body 1 through the valve plate 2 rotation shaft. The rotation of the valve plate 2 rotation shaft drives the valve plate 2 to rotate inside the valve body 1.

[0034] The adjustment assembly 3 includes an adjustment housing 31, a drive unit 32, an airflow adjustment potentiometer 33, and a mode switching button 34. The adjustment housing 31 is detachably mounted on the top of the valve body 1. The drive unit 32, the airflow adjustment potentiometer 33, and the mode switching button 34 are all detachably mounted inside the adjustment housing 31. The drive end of the drive unit 32 is detachably connected to the valve plate 2. The airflow adjustment potentiometer 33 is rotatably mounted on the adjustment housing 31. Both the airflow adjustment potentiometer 33 and the mode switching button 34 are electrically connected to the drive unit 32. When the mode switching button 34 is switched to manual mode, the drive unit 32 drives the valve plate 2 to rotate according to the potential in the airflow adjustment potentiometer 33. In this embodiment, the regulating housing 31 is detachably mounted on the top of the valve body 1 by means of screws. The drive unit 32, the airflow adjustment potentiometer 33, and the mode switching button 34 are all detachably mounted inside the regulating housing 31 by means of screws. The drive end of the drive unit 32 passes through the valve body 1 and is detachably connected to the top of the valve plate 2 by a snap-fit ​​connection. This allows the drive unit 32 to rotate the valve plate 2 within the ventilation channel of the valve body 1 during operation, thereby adjusting the airflow within the ventilation channel of the valve body 1.

[0035] This invention, through the arrangement of valve body 1, valve plate 2, and adjusting component 3, allows the user to install the adjusting housing 31 onto valve body 1 during installation. The drive unit 32, airflow adjustment potentiometer 33, and mode switching button 34 are all installed within the adjusting housing 31. After the drive end of the drive unit 32 is fixedly connected to the top of the valve plate 2, the user first adjusts the mode to automatic or manual using the mode switching button 34. When the mode switching button 34 is switched to automatic mode, the drive unit 32 automatically drives the valve plate 2 to rotate, thereby automatically adjusting the rotation angle of the valve plate 2 within the ventilation channel of valve body 1, achieving an automatically set airflow within the ventilation channel of valve body 1. When the mode switching button 34 is switched to manual mode, the operator adjusts the potential on the airflow adjustment potentiometer 33. The drive unit 32 drives the valve plate 2 to rotate according to the potential of the airflow adjustment potentiometer 33, thus quickly adjusting the airflow within the ventilation channel of valve body 1.

[0036] Based on the above embodiments, please also refer to... Figure 1 and Figure 3The drive unit 32 of this utility model includes a motor 321 and a rotating shaft 322. The motor 321 is detachably installed inside the adjustment housing 31. The airflow adjustment potentiometer 33 and the mode switching button 34 are both electrically connected to the motor 321. The two ends of the rotating shaft 322 are detachably connected to the rotating shaft of the motor 321 and the valve plate 2, respectively. Specifically, the motor 321 is detachably installed inside the adjustment housing 31 by screws. The top end of the rotating shaft 322 is fixedly connected to the rotating shaft of the motor 321, and the bottom end of the rotating shaft 322 is detachably connected to the top end of the valve plate 2 by screws. During use, when the mode switching button 34 is switched to automatic mode, the mode switching button 34 cuts off the potential signal between the airflow adjustment potentiometer 33 and the motor 321. The potential signal can be a current signal or a voltage signal. When the mode switching button 34 is switched to manual mode, the potential signal between the air volume adjustment potentiometer 33 and the motor 321 is connected. In this embodiment, the air volume adjustment potentiometer 33 changes the output current signal by adjusting the resistance value, so that the motor 321 controls the rotating shaft 322 to rotate at an angle corresponding to the current signal, thereby driving the valve plate 2 to rotate through the rotating shaft 322, so that the staff can manually adjust the air volume in the ventilation channel of the valve body 1 in a timely manner.

[0037] Based on the above embodiments, please also refer to... Figure 1 and Figure 2 The drive unit 32 of this utility model also includes a motor fixing plate 323, which is detachably mounted on the adjusting housing 31, and the motor 321 is mounted on the motor fixing plate 323. Through the setting of the motor fixing plate 323, the motor fixing plate 323 is detachably mounted on the adjusting housing 31 by screw fixing. The motor fixing plate 323 holds the motor 321 in place, preventing the motor 321 from shaking during operation, thus enabling the motor 321 to work better and allowing the motor shaft 322 to drive the valve plate 2 to rotate more precisely.

[0038] Based on the above embodiments, please also refer to... Figure 1 and Figure 2The mode switching button 34 of this utility model includes a manual command button 341 and an airflow angle button 342. The manual command button 341 and the airflow angle button 342 are respectively inserted into the corresponding adjustment holes. Both the manual command button 341 and the airflow angle button 342 are electrically connected to the drive unit 32. When the manual command button 341 is switched to manual mode, the drive unit 32 drives the valve plate 2 to rotate according to the potential in the airflow adjustment potentiometer 33. Through the setting of the manual command button 341 and the airflow angle button 342, when the user presses the manual command button 341 during use, the resistance of the manual command button 341 changes. This changes the current signal received by the motor 321, causing the rotation of the valve plate 2 to switch to manual mode, thus facilitating the motor 321 to drive the valve plate 2 to rotate according to the potential in the airflow adjustment potentiometer 33. Meanwhile, when the manual command button 341 is not pressed, the resistance of the manual command button 341 remains unchanged, and the rotation of the valve plate 2 driven by the motor 321 switches to automatic mode, thus realizing automatic rotation of the valve plate 2 by the motor 321. Furthermore, when the user presses the airflow angle button 342, the rotation of the valve plate 2 driven by the motor 321 is based on the angle of the valve plate 2; when the user does not press the airflow angle button 342, the rotation of the valve plate 2 driven by the motor 321 is based on the airflow flowing through the open channel of the valve plate 2. This allows the user to easily adjust the airflow in multiple modes.

During use, the user can open the adjustment cover 35 to expose the potential hole and adjustment hole, facilitating operation of the airflow adjustment potentiometer 33 and the mode switching button 34.

[0041] Both the airflow adjustment potentiometer 33 and the mode switching button 34 are electrically connected to the drive unit 32 via the PCB circuit board 36. Because both the airflow adjustment potentiometer 33 and the mode switching button 34 are electrically connected to the PCB circuit board 36, the drive unit 32 can receive changes in current through the circuitry in the PCB circuit board 36, thereby better controlling the rotation of the drive unit 32.
