The invention discloses an anti-return-overflow floor drain and a drainage device, the anti-return-overflow floor drain comprises a water seal body, an anti-return-overflow body, a floor drain cover and a floating ball, the anti-return-overflow body is installed in the water seal body, the floor drain cover is installed at the top end of the anti-return-overflow body, and the floating ball is installed in the anti-return-overflow body; a water outlet is formed in the upper end of the water seal body, and a water seal height H1 is formed between the water outlet and the bottom of the anti-return overflow body; a water passing channel is formed in the anti-return-overflow body, a valve port is formed in the water passing channel, the floating ball is located in the water passing channel and floats upwards to be matched with the valve port, and the diameter of the valve port is smaller than that of the floating ball. The water seal is good in odor-resistant sealing performance and can be effectively prevented from drying up, and water return is effectively prevented; the anti-return-overflow body can be taken out at any time, daily cleaning of sundries is facilitated, blocking is not prone to occurring, the drainage capacity is high, the manufacturing cost is low, and practicability is high.
本发明公开了一种防返溢地漏及排水装置，包括水封体、防返溢体、地漏盖、浮球，防返溢体安装在水封体内，地漏盖安装在防返溢体顶端，浮球安装在防返溢体内；在水封体上端开设有排水口，排水口与防返溢体底部之间形成水封高度H1；在防返溢体内开设有过水通道，在过水通道内设置有阀口，浮球位于过水通道内，浮球上浮与阀口配合，阀口直径小于浮球直径。本发明不仅水封防臭密封性好，而且能有效防止水封干涸，有效阻止返水；防返溢体可以随时取出，方便日常清理杂物，而且不易堵塞，排水能力强，造价成本低，实用性强。
