The invention discloses a water quantity adjustable type water falling device. The water quantity adjustable type water falling device comprises a water leaking disk, a speed regulating disk, a hose,a water guide pipe, a main pipeline, a sealing sleeve, a spring sleeve, a third sleeve, a second sleeve and a first sleeve; the speed regulating disk is mounted in a groove in the water leaking disk;the water leaking disk is communicated with the water guide pipe through the hose; the tail end of the water guide pipe is communicated with the main pipeline; the spring sleeve is mounted at the bottom of the sealing sleeve; the third sleeve, the second sleeve and the first sleeve are connected to and mounted at the top end of the spring sleeve from bottom to top in a sleeving manner. The devicedesign is suitable for mounting of kitchen sinks, the water leaking disk can realize that water can flow out, a leaking net is arranged in the water leaking disk, impurities can be filtered, blockingsheet design of the speed regulating disk can block the water quantity of a water outlet of the water leaking disk, and the flowing speed can be adjusted; when water exists in the basin, the self weight of water presses down the water leaking disk, the journey of the three sleeves is shortened, the water leaking disk falls off, the water speed is increased; when the water quantity is reduced, thejourney of the three sleeves is lengthened, the water falling device is blocked.

A water saving valve is fitted to a hose or a water pipe and mixes air bubbles with water. Water receiving flask part 18 receives tap water from a water pipe 12. Tapered hole part 20 has a flow path whose cross-sectional area is gradually reduced from the upstream side toward the downstream side. Conduit part 32 has a large diameter section 56 and a small diameter section 57. The large diameter section 56 is linked to the tapered hole part 20. The conduit part 32 has a flow path 38 at an axial part thereof whose cross-sectional area is substantially uniform. The large diameter section 56 has an air suction port 30 running through from the flow path 38 of the axial section to the outer peripheral surface. A check valve 64 is inserted into the air suction port 30. Sleeve 50 is rigidly secured to the conduit part 32 by a support body 44 arranged at part of axial hole 90. The sleeve 50 has an eaves-like section 46. The eaves-like section 46 surrounds the outer peripheral surface of the large diameter section 56 with a gap 48 interposed between them. The sleeve 50 surrounds the periphery of the other end of the conduit part 32 with a space interposed between them. Air is sucked in from the gap 48 through the air suction port 30 so that water does not leak if hydraulic pressure is applied in the opposite direction.
