[0013] By adopting the anti-blocking and anti-odor drain pipe hydrophobic device of the present utility model, the filter cartridge can block sundries inside the device, preventing them from entering the drain pipe and playing a role in preventing the pipe from being blocked. Secondly, the floating ball inside the filter cartridge can block the pipe orifice when there is no water inside the device, preventing the odor in the pipe from flowing back and playing an anti-odor role. Finally, this device is designed with two maintenance openings. The upper maintenance opening is connected to the floating ball by a nylon rope, which can be used to maintain the inside of the filter cartridge, and the lower maintenance opening can be used to clean sundries outside the filter cartridge. The effect is very good during actual use. Description of the Drawings
