WATER SAVING PLUG
Document Type and Number:
WIPO Patent Application WO/2011/051998
Kind Code:
A1
Abstract:
A water saving plug mounted to a hose or a running water pipe and mixing air bubbles into water.
A water receiving tube portion (18) receives running water from a running water pipe (12). A restricted hole portion (20) gradually reduces the cross-sectional area of a flow path from the upstream side to the downstream side. A conduit portion (32) has a large-diameter section (56) and a small-diameter section (57). The large-diameter section (56) is connected to the restricted hole portion (20). The conduit portion (32) has in a shaft section thereof a flow path (38) having a substantially uniform cross-sectional area. The large-diameter section (56) has an air suction opening (30) penetrating from the flow path (38) in the shaft section through to the outer peripheral surface of the shaft section. A check valve (64) is inserted in the air suction opening (30). A sleeve (50) is affixed to the conduit portion (32) by a support body (44) provided to a part of a shaft hole (90). The sleeve (50) is provided with 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) provided therebetween. The sleeve (50) surrounds the other end of the conduit portion (32) with a space provided therebetween. Air is sucked from the gap (48) through the air suction opening (30), and water leakage does not occur even if water pressure is applied in the opposite direction.
