Spray type water-saving flushing device

The utility model relates to a spray type water-saving lavatory device which comprises a basin cavity of the lavatory device and a water storage folding device, wherein an ejector nozzle is arranged at the junction position of the rear side wall of the basin cavity and a notch plate, and the ejector nozzle is communicated with a control valve via a fluid jet connection pipe. The control valve and a water supply pipe are communicated, and a water replenishment tank and the fluid jet connection pipe are communicated. At least one flooding nozzle is arranged in the basin cavity, the nozzle and a cleaning control valve are communicated via a cleaning connection pipe. Because high-pressure spraying flow crushes rapidly dejecta in the water storage folding device and the dejecta is brought out into a drainage, the water cleaning effect is enhanced, the water consuming amount is cut down, and the crushed dejecta is not easily pasted with a blow-off line. Therefore, jam is not caused. The utility model removes a water chamber and saves lavatory space.
