Abstract:
A spray-adjustment structure of a shower head, the spray-adjustment structure comprising:a front body provided with a vibrating water discharging hole, a water-emitting hole, a shaft tube, and a circular frame located between said water discharging hole and said water emitting hole, said shaft tube provided with a vibration member and a water flow orienting member whereby said vibration member has a plurality of blades and a baffle located between two adjoining blades, and said water flow orienting member has a plurality of indentations and a through hole;a movable circular body having a center hole which is provided with a plurality of ribs, and a washer corresponding in location to said circular frame of said front body whereby said washer and said movable circular body are provided therebetween with a plurality of water-admitting holes, said movable circular body provided with a plurality of water-spraying grooves, a washer which is disposed on the back edge of said movable circular body, and a sealing ring disposed on the back edge of said center hole of said movable circular body;an action member provided in a front end thereof with a plurality of insertion ribs symmetrical to each other, and in a periphery thereof with a plurality of moving edges;a clamping member engaged with a rear end of said action member and provided with a first stepped edge, a second stepped edge, inner threads, and a self-locking edge of a serrated construction;a rotating seat provided with a circular protruded edge corresponding in location to said first stepped edge of said clamping member, and a retaining slot corresponding in location to said insertion ribs of said action member, said rotating seat further provided with a center fitting hole which is provided on a back edge thereof with a sealing ring, and in an inner wall thereof with a radially-oriented rib, said rotating seat further provided with a rotating column, and a circular protrusion corresponding in location to said washer of said movable circular body;a locating member disposed on said second stepped edge of said clamping member and provided in a center thereof with a tubular portion having therein a threaded rib and urging said sealing ring of said rotating seat whereby said tubular portion is provided in a rear end thereof with an inner stepped edge, said locating member further provided with an arresting column corresponding in location to said rotating column of said rotating seat;a pull member provided with a slide slot corresponding in location to said radially-oriented rib of said rotating seat, a tubular seat having a spiral groove and corresponding in location to said tubular portion of said locating member, a valve ring disposed on a front edge of said tubular seat such that said valve ring is corresponding in location to said center fitting hole of said rotating seat, and an axial hole having a column which is provided with a threaded hole, said pull member being so disposed that a front end of said pull member presses against said sealing ring of said center hole of said movable circular body, and that said column of said axial hole of said pull member urges said water flow orienting member of said shaft tube of said front body, and further that said threaded hole of said column of said axial hole of said pull member is engaged with a fastening bolt which is received in said shaft tube of said front body and said through hole of said water flow orienting member of said shaft tube of said front body;a valve disposed in said inner stepped edge of said tubular portion of said locating member such that said valve is corresponding in location to said axial hole of said pull member whereby said valve is provided with two valve rings and a circular frame;a tube connecting member provided therein with threads, and in a front end thereof with a spherical body having a water admitting hole; anda shell provided with an end portion for receiving said tube connecting member, and a threaded protrusion corresponding in location to said inner threads of said clamping member, said shell further provided with a self-locking portion of a serrated construction, said end portion of said shell provided in a front end thereof with an extension tube and a sealing ring which is disposed between said spherical body of said tube connecting member and said circular frame of said valve;said water emitting holes of said front body being completely separated from said vibrating water discharging hole of said front body by said washer of said movable circular body and said circular frame of said front body; said water emitting holes of said front body and said water-spraying grooves of said movable circular body sharing a common water pathway due to said washer of said movable circular body being located between said water-spraying grooves of said movable circular body and said water-admitting holes of said movable circular body, in conjunction with said circular protrusion of said rotating seat; said locating member being located securely between said second stepped edge of said clamping member and said threaded protrusion of said shell due to the fact that said self-locking edge of said clamping member is engaged with said self-locking portion of said shell.
