Abstract:
1. A manual pressing device for a flusher, said flusher including a lateral hole formed in a lower portion of a body of said flusher, a water exhausting passageway formed lengthwise below said lateral hole and possible to communicate with said lateral hole, a lengthwise hole formed in an annular wall of said body and communicating with a chamber formed thereon and also with said lateral hole, said manual pressing device provided in said lateral hole and normally stopping water from flowing from said lengthwise hole into said water exhausting passageway and pressed to permit water flow through the lengthwise hole into said water exhausting passageway, said manual pressing device comprising: a stop ring fitted firmly around the wall defining said lateral hole of said body of the flusher and having a center slide hole: a pressing rod unit located in said center slide hole of said stop ring and consisting of a cap-shaped pressing member and a large diameter rod member and a small diameter rod member extending from said large diameter rod member outward, said large diameter rod member having an annular recess of a certain length formed in an outer surface and communicating with said lengthwise hole of said body, an anti-leak gasket fitted tightly respectively around two locations at two opposite sides of said leak recess of said large diameter rod member for preventing water from leaking, said large diameter rod member and said small diameter rod member possible to be pushed inward by said cap-shaped pressing member fitting with an outer end of said small diameter rod member so that said leak recess may communicate with said water exhausting passageway for water to flow through said lengthwise hole into said water exhausting passageway for flushing: a spring having an inner end pushing against an outer side of said stop ring and an outer end pushing against an inner side of said cap-shaped pressing member, said spring pushing said large and said small diameter rod member back to their original position after they are pushed inward by said pressing member by means of its resilience after said pressing member is released from pressed: and, a nut having an center hollow for receiving partially said stop ring, said spring, said large diameter and said small diameter rod member, said nut having its inner side screwing with an outer side of the wall defining said lateral hole and sealing said stop ring and limiting said large and said small diameter rod member from moving out of said center slide hole of said stop ring, wherein said stop ring further has an inward lengthwise projection, and an anti-leak gasket fitted in an inner wall of said projection so that said anti-leak gasket contacts tightly with an outer side of the wall defining said lateral hole of said body, and a tubular wall is provided to extend lengthwise inward from said projection and has its outer end extending outward from said lateral hole and exposing in said water exhausting passageway and also its interior hollow connected with said center slide hole of said stop ring, at least a leak hole formed laterally at a preset location of said projection so as to let said lengthwise hole of said body communicate with said leak recess via said leak hole, and said two anti-leak gaskets of said large diameter rod member also contacting tightly with an inner wall surface of said center slide hole.
