Definitions

  • the invention relates to a nozzle for saving water and in particular to a nozzle capable controlling and managing the flow of water.
  • the nozzle can be used in the household to reduce the consumption of drinking water for domestic purposes.
  • the nozzle can serve as an adapter for installation in various types of plumbing faucets, faucet mixers and sinks, shower heads, hoses, fountains and others.
  • the prospective application of the water saving devices is those that reduce the flow rate, which can be further installed on the outlets of the plumbing installations. They are small in size, relatively simple in design and interchangeable, making them economical for mass use. As criteria for assessing these devices, it is appropriate to use modern trends and requirements in the field of household water use. However, it is not always possible to achieve optimal service comfort.
  • One of the most important indicators for modern water-saving nozzles is the flow rate of water, pressure and coverage area of the stream, which affect both efficiency and comfort during use.
  • Each of these indices corresponds to a specific user requirement. For example, the nozzle must be designed so that the flow of water is reduced as much as possible, while providing a larger coverage area for washing, with relative preservation of the spray force. - -
  • Numerous nozzles are known for regulating the flow of water. It is known from a CN2596148Y nozzle containing a cylindrical body with an opening and capable of mounting to the end of a plumbing outlet, whose opening is dead end and the walls of the body are provided with water drainage slots which contact the dead end opening. On the body there is a water flow limiting jack so that there is a narrow annular air gap between it and the outer cylindrical surface of the body in which the water streams passing through the slots can flow freely.
  • This nozzle forms a hollow outflow of water, which slightly accelerates into the gap, but the stream is segmented as a result of leakage through the slots and is not homogeneous and continious. This creates a prerequisite for side splash.
  • the described nozzle is designed for use in low- pressure plumbing installations for outflow augmentation, but is not designed to save water.
  • nozzle known from CN2801894Y comprising of a cylindrical body with an opening and capable of mounting to the end of a water outlet whose opening is with dead end downstream of the jet and is made in a cylindrical protrusion along the axis of the body, as between the outer cylindrical surface of the protrusion and the inner surface of the body wall is formed a gap through which the water flows and on the wall of the body there are circularly arranged passageways for draining the water which also contact the deaf opening.
  • a sealing ring between the protrusion and the wall of the body regulates the flow of leaking water.
  • This nozzle also forms a hollow outflow of water which slightly accelerates into the grooves, but the stream is segmented as a result of leakage through the slots and is not homogeneous and continuous, resulting in side splash.
  • the known nozzle is also not suited to limit the flow of water while maintaining comfort during use.
  • the outflow of water is a hollow cylinder and is composed of a plurality of jets which, through a complex system of differently oriented holes, are interwoven so that the outgoing total flow of water is in the form of a knotted net.
  • a nozzle for saving water to be mounted at the end of a plumbing outlet which contains a cylindrical body with a passage hole along the flow of the stream, in which a conical core with a tip against the flow is mounted, which is fixed to the walls of the cylindrical body by three teeth through 120°, as the base of the conical core and the inner surface of the body wall formed a gap through which the water flows.
  • the surface of the outflow water stream is increased by changing the shape of the nozzle outlet, as the water flow strength is not reduced, so the daily wash time can be shortened, resulting in water savings.
  • This nozzle can not create a thin stream of even density, nor reduce the side splash.
  • the nozzle includes a body with a passage hole with the possibility of mounting to the end of a plumbing outlet, as well a swirler mounted in the body opening, and a water flow limiter.
  • a swirler is mounted in the body in right before the outlet, in which the stream divided into two streams is fed into two opposite spiral channels, broken down into drops.
  • the body has a conical outlet proceeding into a small diameter hole downstream of the stream, serving to limit the flow of water and finer breaking the jet of small drops.
  • VVO2017136209 a nozzle for saving water comprising of a body with a passage hole with the possibility of mounting to the end of a plumbing outlet, a swirler mounted in the body opening, and a water flow limiter.
  • the water flow limiter is not a single detail and is shaped as an opening with a closing cone ending with a small diameter bore of the body outlet after the swirler.
  • this known nozzle works on the principle of aerators, spraying the stream into small droplets, which reduces the efficiency of operation.
  • the spray effect of miniature water droplets results from the swirling effect on the jets flowing through the spiral two, three or four channels of the swirler that meet the walls of the closing cone of the water flow limiter and leave the nozzle through the small outflowed cylindrical bore. This does not eliminate the side splashing because the stream is not concentrated in a thick thin annular wall that has a smoother coverage area.
  • the purpose of the present invention is to create a water saving nozzle which is simple in design and easy to clean, providing maximum reduction in water flow while maintaining wash efficiency and time of use.
  • a nozzle for saving water including a body having passage hole capable of mounting to the end of a plumbing outlet, a swirler mounted in the body opening, and a water flow limiter.
  • the flow limiter is inserted into the opening of the body before the swirler in the downstream direction and has a reducing opening in its center.
  • the high speed after the flow limiter is reduced by the swirler and the outlet has a low exit velocity, thus not spraying away from the desired zone.
  • the lack of splashing depends on the type of stream, the consistent wall of the hollow stream prevents any random splashing.
  • the flow limiter performed as a single detail, leads to avoiding the problems of the known nozzles as the clogging of the reducing hole requiring the change of the entire nozzle, but the present nozzle being easily
  • the swirler is a rotary body with axially formed open spiral grooves on its outer surface so that along each channel its section has a smoothly increasing width. In this way, the stream flows relatively evenly through the expanding channels, forming several jet streams with a spiral trajectory, which at the outlet are collected in a single wall without breaking into a number of tiny drops.
  • the passage hole of the nozzle body has at least one step for the flow limiter. Following the step for the limiter downstream the flow, there are at least two adjacent intersected conical sections. The last two of the intersecting conical sections in the downstream direction are an internal collecting cone and an outwardly extending cone that have a
