Definitions

  • the present invention generally relates to a discharging structure of a faucet with a closed hollow water curtain, more particularly to that water around an outlet is along the edge of a retaining portion, inside the outlet, to fall down vertically for forming the closed hollow water curtain in order to enlarge the area of flush for improving the flush efficiency and saving the amount of discharging water.
  • the type of discharging water of General faucet is solid cylindrical that flushes partial area, and user shall continuously move hands to wash hands or goods. It is definitely inconvenient. People skilled in the art thus develop an improved faucet structure with a larger flush area.
  • the upper portion of the improved faucet structure connects with a discharging tube extending forward.
  • the bottom surface of the end of the discharging tube has a U-type outlet. Therefore, water overflowing from the U-type outlet will form a half-open water curtain for saving the amount of flowing water and enlarging a flush area.
  • the purposes of saving the amount of flowing water and enlarging a flush area are achieved, user may still move hands continuously, thus, the shortcoming of prior arts is still not solved.
  • a discharging structure of a faucet being able to form a closed hollow water curtain through an outlet in order to totally enlarge the area of flush and the efficiency of flush shall be an important issue for people skilled in the art.
  • the discharging water curtain of the outlet of prior faucet structure is half-open shape, and that will not completely wash hands, so user shall continuously move hands during washing. It is a disadvantage.
  • the present invention provides a discharging structure of a faucet with a closed hollow water curtain.
  • the discharging structure comprises a faucet member, a discharging tube, extending forward, being disposed at the upper portion of the faucet member, an outlet being disposed at the front end of the discharging tube, a retaining portion being disposed inside the outlet so as to let flowing water around the outlet be along the edge of the retaining portion to vertically fall down for forming the closed hollow water curtain.
  • the present invention provides a discharging structure of a faucet with a closed hollow water curtain.
  • Water around the outlet is along the edge of the retaining portion, inside the outlet, to fall down vertically for forming the closed hollow water curtain.
  • the water curtain may enlarge the area of flush for improving the flush efficiency and saving the amount of discharging water.
  • a discharging structure of a faucet with a closed hollow water curtain includes: a faucet member 10, a discharging tube 11, extending forward, is disposed at the upper portion of the faucet member 10, an outlet 111 is disposed at the front end of the discharging tube 11, the shape of the outlet 111 is selected from the group consisted of: square, round, diamond, triangle, oval, and any other shapes, a retaining portion 12 is disposed inside the outlet 111, the retaining portion 12 extends downward to the edge of the discharging tube 11, the edge of the retaining portion 12 keeps a gap with the edge of the outlet 111, the shape of the edge of the retaining portion 12 is the same as the shape of the edge of the outlet 111, so that a corresponding annular slit 121 is formed between the retaining portion 12 and the outlet 111, the shape of the slit can be square, round
  • the retaining portion 12 being disposed inside the outlet 111 of the faucet member 10 and a gap being between the edge of the outlet 111 and the edge of the retaining portion 12 to form the annular slit 121, the flowing water around the outlet 111 along the edge of the retaining portion 12 will vertically fall down for forming the closed hollow water curtain after the faucet member 10 connects with a water-supply end.
  • the water curtain may enlarge the area of flush for improving the flush efficiency and saving the amount of discharging water.
  • the retaining portion 12 extends downward to be out the outlet 111, the peripheral of the portion, out the outlet 111, of the retaining portion 12 being disposed a flange 122, thus the flowing water around the outlet 111 will be along the flange 122 to vertically fall down, the diameter of the falling water is thus enlarged so as to improve the flush efficiency.
  • the discharging tube 11 and the retaining portion 12 of the faucet member 10 can be integrally produced, as shown from Fig. 1 to Fig. 5 , otherwise both can be manufactured respectively and then assembled.
  • the edge of the outlet 111 of the discharging tube 11 extends downward to form a connecting tube portion 112, the retaining portion 12 has a water-collection room 123 opened upward, the open of the water-collection room 123 connects with an assembling tube 124 so as to connect with a connecting tube portion 112 of the outlet 111, the bottom of the assembling tube 124 has at least one flowing hole 125 that connects with the water-collection room 123, the diameter of the falling water is thus enlarged so as to improve the flush efficiency.
  • FIG. 9 and Fig. 10 which illustrate a fourth preferred embodiment of the present invention.
  • a hollow hole 113 is above the outlet 111 of the discharging tube 11.
  • the edge of the outlet 111 extends upward to dispose the retaining portion 12. While a water level is over the retaining portion 12, the water will be along the inner edge of the retaining portion 12 to fall down vertically for forming the closed hollow water curtain.
  • Fig. 11 and Fig. 12 which illustrate a fifth preferred embodiment of the present invention.
  • the edges of the outlet 111 and the hollow hole 113 extend to form two retaining portions 12 respectively, a gap is between the two retaining portions 12. While a water level is over the retaining portion 12 of the outlet 111, the water will be along the inner edge of the retaining portion 12 to fall down vertically for forming the closed hollow water curtain.
  • the present invention has the following advantage that is described below.
  • Water around the outlet 111 is along the edge of the retaining portion 12, inside the outlet 111, to fall down vertically for forming the closed hollow water curtain.
  • the water curtain may enlarge the area of flush for improving the flush efficiency and saving the amount of discharging water.
