Abstract
This is a type of connection device between a toilet and a drainpipe, including a trap with an inlet connected to a toilet flush port and an outlet connected to the drainpipe. The trap has a bend part and a horizontal lower pipe connected to it. Upper and lower inner pipe walls of the horizontal lower pipe have different declination angles. There is a containing part in the inlet; and in the containing part there is a sealing part forming a sealing structure between the flush port and the inlet. This simplifies the complex structure of existing toilet drainage parts for on-site installation and for reliable use. The separated trap design includes structure that can generate a siphon phenomenon. At the time of sale, wash-down drainage can be easily transformed to siphon wash-down drainage just by changing parts, such as the trap of the toilet, thus improving the drainage effect.
