Then, inflate the inside of the inflation telescopic pipe 8 to push the cleaning scraper 9 to move inside the drain pipe body 4, pushing the impurities into the water trap 1 and out through the drain outlet 12. The self-cleaning coating 3 inside the water trap 1 is made of carbon dioxide. The titanium coating and self-cleaning coating 3 prevent stains from adhering to the inside of the water trap 1. The high-temperature resistant layer 10 and antibacterial layer 11 on the inside of the drain pipe body 4 have the effects of high temperature resistance and antibacterial properties. The water trap 1 can be removed from the drain pipe body 4. When removing it, simply rotate the connecting pipe 2 to separate it from the drain pipe body 4. The drain port 12 on the water trap 1 facilitates sewage discharge. Since the weight of some particulate impurities is greater than that of the transported liquid, the impurities accumulate at the lowest point of the water trap 1. After opening the connecting cover 13, the impurities can be discharged from the drain port 12 to achieve cleaning. This structure realizes the function of easy disassembly and cleaning.
