[0002] A trap refers to an accessory with a water seal installed inside a sanitary appliance or on the drainage pipe section of the appliance. A trap is an accessory that sets a water column of a certain height on the drainage pipe of a sanitary appliance or inside the sanitary appliance to prevent the gas in the drainage pipe system from entering the room. The water column of a certain height inside the trap is called a water seal. The trap is one of the main accessories of the drainage pipe in a building. Some sanitary appliances already have a trap in their structure. When the structure does not have the connection with the industrial wastewater receiver and the domestic sewage pipe or other drainage pipes that may produce harmful gases, a trap must be installed below the drain outlet.

[0003] The water trap currently in use needs to have a water outlet installed at the very bottom to facilitate cleaning of the interior. The water outlet currently used is just a threaded cover installed at the very bottom to seal the water outlet. When cleaning the inside of the water trap, the threaded cover is rotated down, but there will be sewage inside the water trap. If it is rotated down directly, the internal sewage will be directly spilled out, which can easily flow onto the maintenance personnel and affect the overall maintenance effect. Utility Model Content
