When the trap assembly 100 is normally used, the buoyancy switch 50 rises as the water level increases, and the through hole 510 communicates with the water outlet passage 70, so that the trap assembly 100 normally operates. When the trap assembly 100 is not in use, water in the trap assembly 100 can evaporate or leak, the buoyancy switch 50 descends due to the action of gravity, and the blocking portion 530 covers the water outlet 130, i.e., blocks the water outlet channel 70, so as to prevent odor, cockroaches and other small insects in the drainer communicated with the water outlet 130 from entering the trap assembly 100.
