The present invention relates to the technical field of floor drains, in particular to an anti-odour and anti-clogging vertical floor drain convenient for cleaning.
Floor drain is a common facility in home life, usually installed in bathrooms, kitchens and other places. Its function is to drain water and prevent sewage from flowing backwards, and keep the room dry and clean. Floor drains are generally made of metal or plastic and have certain corrosion resistance. In daily use, it needs to clean the floor drain regularly to prevent blockage, and pay attention to avoid falling debris into it. In short, the floor drain, though seemingly insignificant, plays an important role. Proper use and maintenance of floor drain can ensure the health and comfort of family environment.
The blockage of floor drain is one of the common problems in family life. Floor drain is usually used for drainage, but it is easy to accumulate dirt and sundries if it is not cleaned for a long time, leading to blockage. Moreover, in daily use, the odor in the drainage pipeline is easy to flow backward into the room, which leads to the indoor odor. Therefore, the prior art discloses various floor drain drainage devices to solve the technical problems mentioned above.
For example, in the existing U.S. patents:
the patent with a publication number of US20230040521A1 discloses a floor drain structure for preventing hair blockage, wherein a staggered cross bar structure can be used to wind hair conveniently and avoid blocking the drainage hole, but the patent does not have the function of preventing odor from flowing backwards;
the patent with a publication number of U.S. Pat. No. 7,150,576B1 discloses a non-blocking drainage device for surface drainage device, which includes a basket with a side opening, allowing wastewater to flow through it and enter the drainage pipe with the basket; this patent can intercept the sewage in the water to avoid floor drain blockage, but it does not have the function of preventing odor from flowing backwards;
the patent with a publication number of US20160060857A1 discloses an insect-proof and anti-odour drainage device, wherein water flows into the base, and then flows through the wall and rises along the wall in a roundabout way, so that part of the water flows into the drainage pipe from the through hole, and it is stored in the base to prevent insects and odor from entering from the drainage hole; however, this patent is inconvenient to disassemble the floor drain for cleaning and anti-clogging.
