The invention relates to a foam and water spraying switching device comprising a valve element assembly, a connecting sleeve and a foam spraying sleeve; the device is characterized in that the connecting sleeve is connected with the foam spraying sleeve, a cavity is formed in the connecting sleeve and the foam spraying sleeve, the valve element assembly is arranged in the cavity and is in threaded connection with the foam spraying sleeve, a cylinder is arranged on the valve element assembly, a guide hole is formed in the foam spraying sleeve, and the cylinder and the guide hole are opened and closed. Conversion between water spraying and foam spraying is achieved. The foam and water spraying switching device has the beneficial effects that opening and closing of the guide holes in the foam spraying sleeve are controlled through pressure, time and labor are saved, two spraying guns do not need to be used alternately, and the cleaning efficiency is high.
一种泡沫、喷水切换装置,包括阀芯组件、连接套以及泡沫喷套,其特征在于,连接套与泡沫喷套连接且内部形成空腔,空腔内设置阀芯组件,阀芯组件与泡沫喷套螺纹连接,阀芯组件上设置圆柱体,泡沫喷套上设置导向孔,圆柱体与导向孔开合,实现喷水与喷泡沫之间的转换。本发明的有益效果为:本发明通过压力来控制泡沫喷套中的导向孔的开合,省时省力,并且无需两把喷枪交替使用,清洗效率高。
