Negative pressure type water-saving closestool
The invention discloses a negative pressure type water-saving closestool which comprises a closestool seat, a closestool cover, an inner container installed in the closestool seat, a water storage elbow communicated with an outlet of the inner container and a negative pressure fan arranged in the closestool seat, a water outlet of the water storage elbow is communicated with a drain outlet of the closestool seat, and a suction opening of the negative pressure fan is communicated with the water outlet of the water storage elbow. The air pump is used for pumping air in the water outlet of the water storage elbow so that negative pressure can be formed on the water outlet side of the water storage elbow. Negative pressure is formed on the water outlet side of the water storage elbow through the negative pressure draught fan, part of water in the inner container is sucked out in advance through the pressure difference effect and passes through the water outlet of the water storage elbow, and therefore the siphon effect is triggered, the rest of water and dirt in the inner container are sequentially discharged through the water outlet of the water storage elbow, and toilet flushing is smoothly achieved. A large amount of water does not need to be additionally used for submerging the water storage elbow to trigger the siphon effect, and therefore water resource waste can be reduced as much as possible on the basis that toilet flushing is smoothly achieved.
本发明公开一种负压式节水马桶，包括桶座、桶盖、安装于桶座内的内胆、与内胆的出口连通的存水弯头，存水弯头的出水口与桶座的排污口连通，还包括设置于桶座内的负压风机，负压风机的抽风口与存水弯头的出水口连通，用于抽出存水弯头的出水口内的空气，以在存水弯头的出水侧形成负压。本发明通过负压风机在存水弯头的出水侧形成负压，利用压差作用将内胆中的部分水先行吸出并通过存水弯头的出水口，从而触发虹吸效应，使得内胆中的其余水及污物陆续通过存水弯头的出水口排出，顺利实现冲厕，相比于现有技术，无需额外使用大量水去淹没存水弯头以触发虹吸效应，因此能够在顺利实现冲厕的基础上，尽量减少水资源浪费。
