The dustproof net 6 is set on the outside of the movable blade 4. Several sets of rain shields 8 are evenly arranged and installed inside the fixed frame 7. The movable blade 4 is driven by the drive assembly 3 to adjust the opening angle and regulate the ventilation volume of the air valve. When the movable blade 4 is closed, it can block the flow of indoor and outdoor air and play a role in heat preservation. The filter screen 5 and the dustproof net 6 form a multi-layer protective structure, which plays a role in filtering rodents and insects. The fixed frame 7 and the rain shields 8 form a rainproof structure, which plays a role in rainproofing, filtering and heat preservation during use.

[0019] The partition plate 2 is vertically fixed inside the air valve housing 1. The partition plate 2 divides the internal cavity of the air valve housing 1 into the maintenance cavity 21 and the ventilation cavity 22. The internal drive component 3 can be inspected through the maintenance cavity 21, which facilitates operation.

[0020] The drive assembly 3 is installed in the maintenance chamber 21 inside the air valve housing 1. The drive assembly 3 includes a support base 31, an electric actuator 32 is mounted on the outside of the support base 31, and a transmission assembly 33 is mounted on the inside of the support base 31. The support base 31 is fixed to the side of the partition plate 2. The electric actuator 32 is connected to the transmission assembly 33. Several sets of transmission assemblies 33 are all connected to the movable blade 4. The electric actuator 32 and the transmission assembly 33 drive the movable blade 4 to rotate, thereby controlling the opening angle of the movable blade 4.

[0021] The transmission assembly 33 includes a rocker arm 331, a connecting rod 332 is mounted on the outside of the rocker arm 331, the rocker arm 331 is mounted on the end of the rotating shaft of the movable blade 4, and the connecting rod 332 connects two adjacent sets of rocker arms 331, thereby driving the two adjacent sets of rocker arms 331 to rotate simultaneously.

[0022] Several sets of movable blades 4 are installed in the ventilation cavity 22 inside the outer shell 1 of the air valve. The junctions of two adjacent sets of movable blades 4 are staggered and stacked. The stacked structure of the movable blades 4 improves the sealing performance of the movable blades 4 when closed, thereby improving the heat preservation effect.
