Definitions

  • the present disclosure relates to a nozzle structure of a watering device, especially to a rotor nozzle structure with the advantages of easy assembly and steady operation.
  • the conventional structure of rotor nozzle as claimed in patent US9931652 discloses a housing 2 having a conical chamber 3 as an accommodation for a rotor 12 in column shape, the rotor 12 having one end deployed with water outlet hole 14 connecting to the outlet opening 6 of a spray gun, and the intermediate element 25 having a spherical surface against inner wall of the conical chamber 3 for the rotor 12 in an eccentric arrangement to the longitudinal axis of the conical chamber 3.
  • the fluid flows into the chamber 3, it rotates the rotor 12 with tilt current then turning into a swirling steam of 360 degrees running out of the outlet opening 6.
  • the rotor 12 of this kind of rotor nozzle would also rotate in the chamber 3, thus output fluids would disperse.
  • the present disclosure aims to provide a rotor nozzle adopting a longitudinal chamber to apply on a handy spray gun and preventing the rotor from rotating, so as to let output fluids concentrate.
  • the present disclosure provides a structure of rotor nozzle installed inside the spray unit of a watering device, the spray unit is composed of a mounting member and a housing for mutually defining a chamber having one water inlet and one water outlet, and the chamber deployed with a rotor for its end of water outlet connecting to the water outlet side.
  • at least one stopper set on the inner side of the chamber near the water outlet side is correspondingly matched to multiple guide members on the end of water outlet of the rotor.
  • the rotor has a spherical one end connecting to the water outlet of the watering device. Therefore, the water outlet side of the rotor forms at least two annular positioning areas.
  • the present disclosure further provides a watering device for accommodating aforementioned structure of rotor nozzle.
  • Fig. 1 to Fig. 4 illustrate a spray unit 100 of a watering device
  • the spray unit 100 is rotatably installed on the base 200 of the watering device and mainly assembled by an adjusting member 10 and a mounting member 11 correspondingly.
  • Multiple spray heads are set between the adjusting member 10 and the mounting member 11, the spray heads respectively have a water outlet and a water inlet between the adjusting member 10 and the mounting member 11, the mounting member 11 is connected to the water inlet side 101 of the base 200 of the watering device, and the water inlet side 101 is connected to a water supply.
  • one of the spray heads can be connected to the water inlet side 101 of the base 200, so that water from the water supply flows through the water inlet side 101 and inside of the rotor nozzle, and ejects out from the water outlet side 102.
  • One of the spray heads has structure of rotor nozzle, the structure of rotor nozzle consists of a housing 15, a rotor 20, a flow director 40.
  • the housing 15 is roughly a tubular in shape having its front end engaged to the inner wall of the adjusting member 10, so that the water outlet side 102 of the housing 15 located on the adjusting member 10, and the housing 15 has its rear end connected to the mounting member 11 for mutually defining a chamber 17 with a longitudinal interior.
  • the flow director 40 has an annular base 41 located on the rear opening of the housing 15 and the block 12 on the side wall of the mounting member 11, so that the flow director 40 and the bottom of the mounting member 11 are arranged in a partition formation.
  • the flow director 40 has a center base 45 spaced from the annular base 41, a position rod 47 protruding from the center base 45 forwards to the direction of the water outlet 102, and multiple guide vanes 43 connecting to the inner side wall of the annular base 41 and the outer side wall of the center base 45, the guide vanes 43 are extending along the radial direction of the center base 45 and tangent to the center base 45 respectively at a predetermined angle, a swirl opening 46 is defined between the adjacent guide vanes 43.
  • the swirl opening 46 is arc-shaped and penetrates the two opposite sides of the annular flow director 40.
  • the rotor 20 is installed inside the chamber 17 and forms a hollow column having two ends as a water inlet 21 and a water outlet 22.
  • the rotor 20 has an inner wall fixed with multiple current blades 26 extending to the water inlet 21 in a crossover formation.
  • the rotor 20 has a spherical end 27 disposed of a water outlet 22 connecting to the water outlet side 102 of the adjusting member 10, and the spherical end 27 and the water outlet side 102 form a complementary mechanism.
  • the rotor 20 has its water inlet 21 confined between the inner wall of the chamber 17 and the annular track of the position rod 47 of the flow director 40 for the rotor 20 in an eccentric arrangement, leaning backward and outward, to the water outlet.
  • the present disclosure provides an embodiment, wherein the chamber 17 near the water outlet side 102 is a longitudinal interior with multiple stoppers 18 protruding on the inner wall in annular form, and a slot 19 is formed between the stoppers 18, multiple stop rods are protruded radially on the spherical end 27 of the rotor 20 as guide members 28 and located on the slot 19.
  • each stopper 18 has a bevel on its surface for guiding the surface of the rotor 20 in tilt arrangement, the water outlet side (the spherical end 27, guide members 28) of the rotor 20 forms at least two annular position areas, the rotor 20 rotates steadily and prevents the rotor 20 from rotating, in order to generate a centralized linear current spraying out from the water outlet 22 of the rotor 20 instead of the conical spurt produced by rotation of the conventional rotor.
  • the position rod 47 of the flow director 40 is in a line with the water inlet side 101 and the water outlet side 102.
  • a rod body 25 is extending from one end of the water inlet 21 of the rotor 20 along the rear end of the current blade 26 for locating on the outer wall of the position rod 47 to thereby steady the rotation track of the rotor 20.
  • a bevel is set on the chamber near the water inlet side 101 for guiding the surface in rear of the rotor 20.
  • the chamber near the water outlet side 102 has a longitudinal interior, and three stoppers 18 protruding on its inner wall are arranged equiangular.
  • Multiple slots are arranged radially in an annular form on the water outlet of the rotor 20, the slots are provided as guide members for placing the stoppers 18, in this way, the rotor 20 rotates steadily with its tilt arrangement and prevents the rotor 20 from self rotating.
  • the present disclosure provides an embodiment, wherein the number of the guide members 28 is integer multiple of the number of the stoppers 18, to maintain rotational balance. However, the number of the stoppers 18 also can be only one, to locate the rotor 20.
