Anti-siphon overflow device, closestool waterway system and closestool
The invention discloses an anti-siphon overflow device, a closestool waterway system and a closestool, the anti-siphon overflow device can be installed on a water tank of the closestool, the anti-siphon overflow device specifically comprises an upper cover and a lower seat, the upper cover is installed on the lower seat, a cavity is formed in the upper cover and the lower seat, and the upper cover comprises a cover body, a water inlet, an air vent and a first flow guide structure; the water inlet and the ventilation opening are formed in the cover body, the lower seat comprises a lower seat body, a water outlet, an exhaust opening, an overflow opening and a second flow guide structure, the water outlet and the exhaust opening are formed in the bottom of the lower seat body and communicate with the interior of the water tank, and the second flow guide structure is arranged below the first flow guide structure. Water flows into the cavity from the water inlet and flows into the water tank through the first flow guide structure, the second flow guide structure and the water outlet in sequence, and gas in the water tank enters the cavity through the exhaust port and is exhausted through the overflow port and the ventilation port. When the water tank overflows and the water level is higher than the overflow port, water is discharged from the overflow port, and the anti-siphon and anti-overflow functions can be achieved on the same structure at the same time.
本发明公开了一种防虹吸溢流装置、马桶水路系统及马桶，该防虹吸溢流装置可安装在马桶的水箱上，具体包括上盖和下座，上盖安装在下座上并与下座的内部形成腔体，上盖包括盖体、进水口、通气口和第一导流结构，进水口和通气口均设于盖体上，下座包括下座本体、出水口、排气口、溢流口和第二导流结构，出水口和排气口设于下座本体的底部并与水箱内部连通，第二导流结构设于第一导流结构下方，在正常进水过程中，水从进水口流入腔体并依次经过第一导流结构、第二导流结构和出水口流入水箱内，水箱内的气体通过排气口进入腔体并经溢流口和通气口排出；当水箱发生溢水且水位高于溢流口时，水从溢流口排出，可在一个结构上同时实现防虹吸和防溢流功能。
