Abstract

A water-guide device in a tap, which includes an outlet connector with a circular plate, being mounted on the water outlet of a tap; the circular plate of the outlet connector is mounted on a positioning seat by means of a bubble head; the other end of the outlet connector is formed into a cylindrical part to be connected together with a guide pipe; the guide pipe extends through a passage of the body portion of the tap, and to the outer end of a concave seat of the water inlet; the guide pipe is connected with a snap connector having a partitioning ring, and then is connected with a water valve seat. The guide assembly can provide an isolation structure between the water valve seat and the bubble head so as to prevent water stream containing heavy lead from contact with the tap, i.e., to avoid lead being dissolved into water to jeopardize.

Claims

1. A water-guide device in a tap, in which a thread portion for mounting a bubble head on water outlet being furnished, and inside said thread portion, a positioning seat being provided;

center of said tap having a through hole;

water inlet of said tap having a concave seat and a through hole, and between said water inlet and said water outlet, a passage part being provided to have said water inlet and said water outlet become communicating each other;

center of a H-shaped water valve seat having a concave seat and cylindrical hole;

plane surface of said H-shaped water valve seat extended beside to form a plurality of fixing plates with round holes for receiving screws so as to have a body portion fastened in place;

a guide assembly being mounted between said water inlet and said water outlet in said body portion, and said guide assembly including;

an outlet connector made of a metal piece punched into a form, and said outlet connector having a circular plate to be mounted on a positioning seat;

said outlet connector having a cylindrical part extended therein, and said cylindrical part connected with a guide pipe, which being fixed in place with a fixing ring;

a said guide pipe made of a plastic material, being temperature-proof and having no poison, and one end of said guide pipe connected with said cylindrical part of said outlet connector, while other end thereof passing through a passage part of said body portion, and a cylindrical hole of a concave seat of said water inlet, and then said guide pipe connected together with a snap connector and being mounted on a concave seat of said body portion;

a said snap connector, of which center cylindrical hole furnished with a guide cylindrical surface and an O-ring groove for mounting a fixing ring and an O-ring therein respectively;

upon said guide pipe passing through said cylindrical hole, said guide pipe being fastened in place by means of claws of said fixing ring so as to prevent said guide pipe from moving;

outer portion of said snap connector having a cylindrical part being smaller than a through hole of said water inlet, and having partitioning ring being slightly smaller than diameter of said concave seat of said tap;

inner cylindrical part of said partitioning ring passing through a through hole of said water inlet of said body portion, and inner said of said partitioning ring mounted on said concave seat of said water inlet;

outer end of said partitioning ring having a stud;

said cylindrical part and said stud of said partitioning ring being connected with said concave seat and said cylindrical hole of said water valve seat.

2. A water-guide device in a tap as claimed in claim 1, wherein said snap connector has a said partitioning ring, of which inner side being mounted on said concave seat of said water inlet of said body portion, and outer side of said partitioning ring mounted on said concave seat of said water valve seat, and passed through a center through hole of said fixture;

between both said inner and outer sides and said concave seats, washers being mounted respectively;

after said fixing plates of said water valve seat being fastened in place with said screws, both said inner and outer sides and said concave seats being in close contact condition.

3. A water-guide device in a tap, in which a water outlet of said tap is provided with threads for mounting a bubble head, and behind said threads, a positioning seat being furnished, and center of said positioning seat having a through hole;

a water inlet of said tap mounted with a hollow thread pipe;

a guide assembly mounted from one end of said hollow thread pipe to said water outlet of body portion of said tap, and said guide assembly including;

an outlet connector being punched into form, and having a circular plate to be mounted on said positioning seat;

said circular plate having a cylindrical part extended inwards, and being mounted with a guide pipe, and connected part of said cylindrical part and said guide pipe being mounted with a fixing ring;

a said guide pipe made of a plastic material, being temperature-proof and having no poison, and one end thereof connected with said cylindrical part of said outlet connector, while other end thereof passing through passage part of said body portion, a hollow thread pipe, and then extended to lower end of said hollow thread pipe;

said guide pipe connected with a snap connector, and then both of them being fastened to said lower end of said hollow thread pipe;

a said snap connector, of which center cylindrical hole furnished with a guide cylindrical surface and an O-ring groove for mounting a fixing ring and an O-ring therein respectively;

upon said guide pipe passing through said cylindrical hole, said guide pipe being fastened in place by means of claws of said fixing ring so as to prevent said guide pipe from moving;

outer portion of said snap connector having a cylindrical part having a diameter less than that of said hollow thread pipe, and having a partition ring being slightly larger than diameter of said hollow thread pipe;

an inner cylindrical part of said partition ring mounted in said hollow thread pipe, while inner side of said partition ring mounted in end of said thread pipe;

outer ring-shaped plane of said partition ring being a plane, which being in close contact with a washer in inner ring-shaped plane of a T-shaped connector, after said partition ring being connected with said T-shaped connector.
