The invention discloses a floor drain with a sewage backflow prevention function. The floor drain comprises a ring-shaped casing, wherein an accommodating cavity is arranged inside the upper end of the casing; a filtering basket is arranged in the accommodating cavity; a filtering plate is arranged at the upper end of the casing; a connecting sleeve is connected to the lower end of the casing through screw threads; a blocking cover is connected to the lower end of the connecting sleeve through screw threads; a plurality of long holes which are uniformly distributed in the circumferential direction are formed in the blocking cover; a hollow floating ball made of a plastic material is arranged between the connecting sleeve and the blocking cover; a silica gel layer covers the outer wall surface of the hollow floating ball; an annular cone surface used for being abutted against the silica gel layer so as to seal and block the annular cone surface of the connecting sleeve after the hollowfloating ball upwards floats is arranged on the inner peripheral wall of the connecting sleeve; the annular cone surface is gradually and inwards contracted from bottom to top; and when the hollow floating ball does not upwards float, a gap is formed between the silica gel layer and the annular cone surface. The floor drain can effectively prevent sewage in a sewer pipeline from backflowing from the floor drain, so that convenience can be brought to a user.
本发明揭示一种具有防污水反涌功能的地漏，包括环形状的壳体，壳体上端的内部设置有容腔，容腔中安装有过滤篮，壳体的上端安装有过滤板，壳体的下端螺纹连接有连接套，连接套的下端螺纹连接有挡盖，挡盖中设置有若干个呈周向均匀分布的长形孔，连接套与挡盖之间设置有由塑料材料制成的空心浮球，空心浮球的外壁面上包裹有硅胶层，连接套的内周壁上设置有在空心浮球上浮后用于与硅胶层相抵以封堵连接套的环形锥面，环形锥面由下至上逐渐向内收缩，空心浮球未上浮时，硅胶层与环形锥面之间留有间隙；本发明能够有效避免下水管道中的污水从地漏中反涌出来，从而能够给用户带来方便。
