Closestool flushing system capable of enhancing pollution discharge suction force
The invention discloses a closestool flushing system capable of enhancing pollution discharge suction. The closestool flushing system comprises a urinal, a siphon elbow and a main flushing nozzle, the bottom of the urinal is communicated with the water inlet end of the siphon elbow, the water outlet end of the siphon elbow is communicated with the sewer pipe, the siphon elbow sequentially forms a first trap and a second trap between the urinal and the sewer pipe, and an airtight section is formed by liquid seal in the siphon elbow; the main flushing nozzle is provided with a main flushing jet orifice, a main flushing air inlet and a main flushing water inlet which are communicated with one another, the main flushing jet orifice faces the water inlet end of the siphon elbow, the main flushing air inlet is communicated with the airtight section, and the main flushing water inlet is communicated with a water source device; water flow supplied by the water source device sucks air in the airtight section through the main flushing air inlet when flowing from the main flushing water inlet to the main flushing jet orifice; similarly, a ring brushing nozzle with the same structure as the main flushing nozzle can be arranged, and air in the airtight section is sucked in the ring brushing process. According to the invention, negative pressure is generated in the siphon elbow by utilizing the Venturi effect, so that the pollution discharge power of the closestool is improved, and the pollution discharge effect is further improved.
本发明公开一种增强排污吸力的马桶冲水系统，包括便池、虹吸弯管和主冲喷嘴；便池底部连通虹吸弯管的进水端，虹吸弯管的出水端连通下水管，虹吸弯管在便池和下水管之间依次形成第一存水弯和第二存水弯，使虹吸弯管内液封形成气密段；主冲喷嘴具有互相连通的主冲喷射口、主冲进气口和主冲进水口，主冲喷射口朝向虹吸弯管的进水端，主冲进气口连通气密段，主冲进水口连通有水源装置，水源装置供给的水流在由主冲进水口流至主冲喷射口时通过主冲进气口吸入气密段内的空气；同样也可以设置与主冲喷嘴结构相同的刷圈喷嘴，利用刷圈过程吸入气密段内的空气。本发明利用文丘里效应使虹吸弯管内产生负压，以提升马桶的排污动力，进而提升排污效果。
