Definitions

  • the present invention relates to a sprayer head assembly and, more particularly, to a sprayer head assembly which is adjustable to output various spray patterns.
  • a sprayer head assembly comprises a substantially cylindrical hollow body with an opening formed in one end thereof, defining a chamber therein.
  • a central circular recess and four peripheral conical recesses are formed on an inner wall of the other end of the cylindrical hollow body.
  • Each peripheral conical recess is in fluid communication with the central circular recess and has a nozzle through which fluid is outputted.
  • a helical slot is formed on a periphery of the cylindrical hollow body.
  • the sprayer head assembly further includes an adjusting means displaceably received in the chamber.
  • the adjusting means includes a fluid passage communicating with the chamber and a coupling means, such as a socket for coupling with an inlet pipe through which water or pesticide solution is applied.
  • a flange is formed on an upper portion of the adjusting means with an annular groove formed therein for receiving a sealing means, such as an O-ring.
  • An elastic arm extends downward from the flange with an adjusting knob at a distal end thereof.
  • Water or pesticide solution from the source flows through the pipe, the inner passage, the central circular recess, and the peripheral conical recess and then sprays out via the nozzles.
  • the adjusting knob is movable along the helical slot to vary the volume of the chamber, thereby varying the patterns of the outputted sprays.
  • a sprayer head assembly according to the present invention comprises a substantially cylindrical hollow body 2 with an opening formed at one end thereof, defining a chamber 24 therein.
  • a central circular recess 53 and four peripheral conical recesses 55 are formed on an inner wall of the other end of the cylindrical hollow body 2.
  • Each peripheral conical recess 55 is in fluid communication with the central circular recess 53 via a respective passage 54 and has a nozzle 56 through which fluid is outputted.
  • a helical slot 22 is formed on a periphery of the cylindrical hollow body 2.
  • the sprayer head assembly further includes an adjusting means 30 displaceably received in the chamber 24.
  • the adjusting means 30 includes a fluid passage 31 communicating with the chamber 24 and a coupling means, such as a socket 38 for coupling with an inlet pipe 52 through which water, pesticide solution, or fertilizer solution is applied.
  • a flange 32 is formed on an upper portion of the adjusting means 30 with an annular groove 33 formed therein for receiving a sealing means, such as an O-ring.
  • An elastic arm 34 extends downward from the flange 32 with an adjusting knob 35 at a distal end thereof. Alternatively, the adjusting knob 35 may directly extend from the adjusting means 30 to the helical slot 22.
  • the adjusting knob 35 is in its lowermost position, such that the chamber 24 is in its largest volume.
  • Water or pesticide solution from the source flows through the pipe 52, the inner passage 31, the central circular recess 53, and the peripheral conical recess 54 and then sprays out via the nozzles 56.
  • the adjusting knob 35 moves along the helical slot 22 to its topmost position, as can be seen in Fig. 4, the chamber 24 is in its smallest volume.
  • the path of the water or pesticide solution is the same as that in Fig. 3, but the stream is stronger than that in Fig. 3 since the volume of the chamber 24 is reduced.
  • annular flanges 36 and 37 may be provided on the socket 38, contacting an inner perpheral wall of the cylindrical hollow body 2 and having an inclining angle the same as that of the helical slot 22 to provide a stable displacement of the adjusting means 30 in the cylindrical hollow body 2.
  • the present invention has the following advantages:
