摘要：【中文】本发明提供了一种清洗用脉冲喷水装置，包括喷水装置主体和进气装置主体，所述喷水装置主体内根据流向依次设有相互连通的进水管、渐缩管、节流管和偏心喷水管，所述进水管、渐缩管和节流管的轴线同轴，所述偏心喷水管的轴线与节流管的轴线偏心布置，且所述节流管与偏心喷水管相内切；第一进气管与所述节流管和偏心喷水管连通面垂直相交；喷水装置主体与进气装置主体止口配合，所述进气装置主体与第一进气管连通；所述进气装置主体进口内放置配重球，用于产生间歇吸气实现控制进气量。本发明人为的在射流中诱发空炮产生，以空炮溃灭的能量增加水射流的能量，可以在较低的压力下获得较好的冲蚀性能，提高清洗能力，节省清水的使用。 【EN】The invention provides a pulse water spraying device for cleaning, which comprises a water spraying device main body and an air inlet device main body, wherein a water inlet pipe, a reducing pipe, a throttle pipe and an eccentric water spraying pipe which are communicated with each other are sequentially arranged in the water spraying device main body according to the flow direction; the first air inlet pipe is vertically intersected with the communicating surface of the throttle pipe and the eccentric water spray pipe; the water spraying device main body is matched with a spigot of the air inlet device main body, and the air inlet device main body is communicated with the first air inlet pipe; and a counterweight ball is arranged in an inlet of the air inlet device main body and is used for generating intermittent air suction to realize control of air inflow. The invention artificially induces the generation of air cannons in jet flow, increases the energy of water jet flow by the collapse energy of the air cannons, can obtain better erosion performance under lower pressure, improves the cleaning capacity and saves the use of clear water.
