The lifting component includes a threaded rod threadedly connected to one end of the sliding rod, and a drive motor is fixedly connected to the top of the threaded rod. The cleaning component includes several sets of support springs fixedly connected to one side of the sliding rod, and a cleaning brush is fixedly connected to one end of each support spring.
[0008] As a further embodiment of this utility model, the valve frame is internally rotatably connected with several sets of rotating columns, and the surface of the rotating columns is fixedly connected with baffles. The baffles serve to block and adjust the ventilation area.
[0009] As a further embodiment of this utility model, a rotating wheel is sleeved on the top of the rotating column, and a rack belt meshes with the surface of the rotating wheel. The rack belt enables multiple sets of rotating wheels to rotate synchronously.
[0010] As a further embodiment of this utility model, an output motor is fixedly connected to the top of one of the rotating columns, and a motor housing is fitted onto the surface of the output motor. The motor housing serves to protect the output motor.
[0011] As a further embodiment of this utility model, a support shell is fixedly connected to the top of the valve frame, and the support shell is fixedly connected to the bottom of the motor housing. The support shell serves to support the rotating wheel.
[0012] As a further embodiment of this utility model, an air volume sensor is sleeved on one side of the valve frame, and one end of the air volume sensor is electrically connected to a controller via a power line. The controller is configured to control the output motor.
[0013] As a further embodiment of this utility model, a positioning rod is slidably connected to the other end of the sliding rod. The positioning rod is fixedly connected inside the valve frame. The positioning rod facilitates the stabilization of the sliding rod's lifting and lowering.
[0014] (III) Beneficial Effects
[0015] This utility model provides a valve for automatically controlling air volume, which has the following beneficial effects:
[0016] 1. This automatic airflow control valve, through the installation component settings, allows for easy installation by aligning the positioning plates on both sides of the valve frame with the outer connecting pipe during installation. Rotating the threaded bolt causes the rotating rod to rotate within the groove on the positioning plate, thus engaging the threaded bolt within the groove of the outer connecting pipe. Rotating the limit nut causes it to rotate at one end of the threaded bolt and press against the surface of the outer connecting pipe. Simultaneously, the positioning plate and the outer connecting pipe clamp the sealing ring, achieving convenient valve installation, saving time and labor costs, and improving maintenance efficiency.
[0017] 2. This valve, which automatically controls airflow, utilizes a lifting and cleaning assembly. When the baffle surface becomes dirty, the drive motor is activated, causing the threaded rod to rotate. The threaded rod then rotates within a threaded hole at one end of the sliding rod, raising and lowering it. As the sliding rod descends, the spring force of the support spring pushes out a cleaning brush on one side of the sliding rod, which then scrapes and cleans the baffle surface. When cleaning is complete, the threaded rod retracts the sliding rod into the top groove of the valve frame, and the cleaning brush compresses the support spring, thus achieving the effect of cleaning the baffle surface. This reduces the workload of disassembling and cleaning the baffle when it becomes dirty, facilitating the continued use of the valve. Attached Figure Description

A sliding rod 6 is slidably connected inside the valve frame 1, and a lifting component 7 is threaded to one end of the sliding rod 6. The lifting component 7 and the cleaning component 8 achieve the effect of cleaning the surface of the baffle 10. To reduce the workload of disassembling and cleaning the baffle 10 when it is dirty, and to facilitate the continuous use of the valve, a cleaning component 8 is fixedly connected to one side of the sliding rod 6. The mounting component 5 includes a rotating rod 501 rotatably connected to the periphery of the positioning plate 2. A threaded bolt 502 is sleeved on the surface of the rotating rod 501.

[0032] In this invention, the working steps of the device are as follows:
[0033] First step: When installation is required, align the positioning plates 2 on both sides of the valve frame 1 with the outer pipe 4, and then rotate the threaded bolt 502 so that the rotating rod 501 rotates in the groove on the positioning plate 2, and then the threaded bolt 502 is inserted into the groove of the outer pipe 4. Rotate the limiting nut 503 so that the limiting nut 503 rotates at one end of the threaded bolt 502 and presses against the surface of the outer pipe 4. At the same time, the positioning plate 2 and the outer pipe 4 clamp the sealing ring 3.
[0034] Second step: When the surface of the baffle 10 is dirty, start the drive motor 702, so that the drive motor 702 drives the threaded rod 701 to rotate, and then the threaded rod 701 rotates in the threaded hole at one end of the sliding rod 6, driving the sliding rod 6 to rise and fall.
[0035] Third step: When the sliding rod 6 descends, the cleaning brush 802 on one side of the sliding rod 6 is pushed out by the elastic force of the support spring 801, and then the surface of the baffle 10 is squeezed for scraping and cleaning. When the cleaning is finished, the threaded rod 701 drives the sliding rod 6 to retract into the top groove of the valve frame 1, and the cleaning brush 802 squeezes the support spring 801 to retract.
