Domestic floor drain capable of preventing water backflow
The invention discloses a domestic floor drain capable of preventing water backflow. According to the domestic floor drain capable of preventing the water backflow, the same side ends of an outer cylinder and a drain core of the floor drain are both in butt joint with the lower portion of a base, and a water inlet of the drain core is in butt joint with a water leakage hole of the base; the floor drain further comprises a floating ball, a trigger, a hook spring and an arc-shaped metal sill; the fixed end of the hook spring is installed on the inner side wall of the outer cylinder, the free end of the hook spring is installed at the end of the metal sill, the two ends of the metal sill are hinged to the inner side wall of the outer cylinder respectively, the middle arc-shaped section of the metal sill abuts against the limiting end of the trigger under the action of the hook spring, and the triggering end of the trigger is connected with the floating ball through a connecting rod; and after the trigger end of the trigger is triggered by the movement of the floating ball, the middle arc-shaped section of the metal sill falls off from the limiting end of the trigger, and the metal sill is pressed on the drain core under the action of the hook spring. The floor drain effectively overcomes the defect that foreign matter or dirty water surges due to blockage of a sewer line of a traditional floor drain, and meanwhile has the advantages of being low in cost, convenient to install, simple in structure and the like.
本发明公开了一种防反水家用地漏，该地漏的外筒、漏芯的同侧端均对接在底座下，该漏芯进水口与底座的漏水孔对接；地漏还包括浮球、触发器、钩簧以及弧形的金属槛；钩簧的固定端安装在外筒内侧壁上，且钩簧的自由端安装在金属槛的端部，金属槛的两端部分别铰接在外筒内侧壁上，金属槛的中间弧形段在所述钩簧作用下顶持在触发器的限制端上，触发器的触发端通过连接杆与浮球连接；在触发器的触发端被浮球的运动触发后，金属槛的中间弧形段从触发器的限制端上脱落，且金属槛在钩簧作用下压紧在漏芯上。本发明有效的消除了传统地漏因下水管道堵塞而存在的异物或脏水上涌的缺陷，同时具有成本低廉、安装方便、结构简单等优点。
