[0012] Beneficial effects of the utility model:

[0013] 1. Compared with traditional building HVAC drainage devices, during use, hair and other easily aggregated objects will enter the drainage pipes, aggregate under the action of water flow, grow larger over time, and are difficult to clean, eventually clogging the drainage pipes, making it difficult for subsequent domestic sewage to be discharged through the drainage pipes, causing inconvenience to users. This device filters out hair and other easily aggregated objects, preventing them from entering the drainage pipes, thereby ensuring the smooth flow of the drainage pipes.

[0014] 2. During filtration, domestic sewage flows into the filter tube through the water inlet pipe, and the sewage flows into the combination of the upper shell and the lower shell, and then flows to the outside through the outlet pipe. Hair and other objects that are easy to aggregate are blocked by the filter holes and remain in the filter tube. In this process, the sealing ring in the sealing groove plays a sealing role, preventing sewage from flowing out from the connection between the filter tube and other components. The interlocking groove and the interlocking protrusion are interlocked with each other, and the sealing strip at the interlocking part plays a sealing role, preventing sewage from flowing out from the connection between the upper shell and the lower shell. This solves the problem that in most building HVAC drainage devices, hair and other objects that are easy to aggregate enter the drainage pipe during use, and aggregate and block the drainage pipe during long-term use, making it difficult for domestic sewage to continue to be discharged through the drainage pipe, thereby enhancing the practical value of the device;

[0015] 3. When cleaning, turn the fixing nut on one side of the fixing seat to release the threaded connection with the fixing bolt, separate the upper shell and the lower shell. Since the lower shell is threadedly connected to the support bolt and thus fixed to the support leg and the support seat, remove the upper shell separately and take out the filter tube for replacement or cleaning.
