[0002] Floor drains are essential facilities in places such as family bathrooms and kitchens, and floor drains with one-way valves are an innovative design that can effectively prevent odor backflow. Floor drains with one-way valves have made significant improvements in function. It uses advanced reverse pressure control technology. When draining, the one-way valve opens to drain sewage smoothly; when the reverse pressure increases, the one-way valve can quickly close to prevent odorous gases in sewage from flowing back into the room, keeping the indoor air fresh.

[0003] For example, the patent specification of an existing Chinese patent (publication number: CN213572284U) discloses a floor drain with a one-way valve. The one-way valve is provided to prevent waste water from entering other branches and causing overflow when water is flowing into other branches and the floor drain at the same time; when no drainage passes through the branch, the one-way valve is normally closed to prevent reptiles and odor.

[0004] However, in the implementation of relevant technologies, it was found that the above-designed floor drain with a one-way valve has the following problems: the floor drain with a one-way valve is only provided with a one-way valve on the inner side of the drain pipe, which makes it easy for impurities to get stuck between the valve body and the inner wall of the pipe when the equipment is used for a long time, causing blockage, making it impossible for the one-way valve to be completely closed, thereby easily causing wastewater backflow. In view of this, a floor drain with a one-way valve is provided to overcome the above-mentioned defects. Utility Model Content
