Abstract:
1. A press touch pop-up stopper used in a basin comprising: a pipe set fixed in an opening of a bottom end of the basin and including a hole disposed therein and having an outlet fixed on a top end of the hole; a stopper assembly received in the pipe set and including a plug, after the plug is pressed, it bounces automatically to turn on the outlet so as to flow water, after the plug is pressed again, it closing the outlet to stop flowing the water; a vertical connecting structure defined between the pipe set and the stopper assembly so that when the stopper assembly is pulled upward, it disengages from the pipe set, and when the stopper assembly is pressed downward to be received in the pipe set, it is connected with the pipe set; a housing installed in the hole from the outlet of the pipe set; a pushing member moving vertically in the housing and including a top end extending out of the housing; a rotating member sliding into the housing upward and to be positioned at an upper position or pushed downward by the pushing member to be retained in the housing and positioned at a lower position; a bottom casing connected with a bottom end of the housing; a spring positioned between the rotating member and the bottom casing so that the rotating member is pushed upward to the upper position, and the rotating member is rotated to be fixed at the lower position; the plug connected with the top end of the pushing member; wherein the housing includes a peripheral wall having an aperture defined in the peripheral wall, the aperture includes four fixing ribs formed therein and separated apart from each other equally, and each fixing rib includes a first beveled face arranged on a top end thereof, between each two adjacent fixing ribs is defined a longitudinal slot, and each longitudinal slot includes a closed wall disposed on a top end thereof, the peripheral wall includes at least one orifice secured thereon vertically; the pushing member includes a plurality of sliding blocks extending outward from an outer surface of a bottom end thereof and spaced apart from each other to move vertically along the longitudinal slots, and each sliding block includes four second beveled faces formed in a serration shape and secured on a bottom end thereof; the pushing member also includes a cavity arranged on the bottom end thereof; the rotating member includes a top end fixed in the cavity of the pushing member and a number of projections secured on an outer surface of a bottom end thereof and spaced apart from each other, each projection includes two third beveled faces formed on a top end thereof, and between the third beveled faces of the projection is defined a retaining fence, the rotating member is slid into the longitudinal slots of the housing by using the projections to correspond to the sliding blocks so as to be positioned at the upper position, and then the third beveled faces are pushed by the second beveled faces of the sliding block to slide out of the longitudinal slots and to further slide along the first beveled faces of the fixing ribs respectively, thus causing a rotation, thereafter the retaining fence is retained in the fixing ribs to be fixed at the lower position.
