An anti-clogging device for the drain outlet of an air source heat pump

Abstract

This utility model relates to the technical field of anti-clogging devices and discloses an anti-clogging device for the drain outlet of an air source heat pump. The device includes a drain pipe with a connecting circular frame on its exterior. The inner top and bottom walls of the connecting circular frame are equipped with limiting components that engage with the outside of the drain pipe. A filter plate is installed on the inner wall of the connecting circular frame. This anti-clogging device for the air source heat pump drain outlet, by incorporating a cleaning component and using a 1-mesh stainless steel filter plate, effectively traps tiny impurities such as dust particles and algae spores, preventing foreign objects from entering the drain pipe and causing blockage at the source. A miniature waterproof servo motor drives a second rotating shaft to rotate, which in turn drives a second bevel gear to rotate, causing a cleaning brush to rotate and scrape away dirt and ice crystals adhering to the filter plate surface in real time. This prevents the mesh from becoming clogged due to the accumulation of impurities, significantly improving the reliability of the anti-clogging device, enhancing its practicality, and making it easier for users to operate.
