Definitions

  • the present invention relates to an internal cartridge for shower heads.
  • shower heads having for example a square or circular shape and made entirely or partially of metal, with extremely high production costs, are commercially available.
  • an extremely low thickness of some plate-like components of structures of internal cartridges of known shower heads entails excessively low stiffness thereof.
  • the aim of the present invention is to provide an internal cartridge for shower heads that has an extremely low thickness and at the same time is made of materials that are alternative to metal and therefore at a low cost.
  • an object of the present invention is to provide an internal cartridge for shower heads that has a low weight with respect to known types of shower head cartridges.
  • Another object of the present invention is to provide an internal cartridge for shower heads that is highly reliable, relatively simple to provide and at competitive costs.
  • an internal cartridge for shower heads comprising a first plate-like element provided with a plurality of holes that are adapted to allow the passage of water, said holes being adapted to accommodate one nozzle each, and a second plate-like element, which is adapted to be coupled to said first plate-like element and to be connected to a water supply pipe, characterized in that said first plate-like element is made of plastic material.
  • the cartridge according to the present invention generally designated by the reference numeral 1, comprises a first plate-like element 2, which is made of plastic material, for example thermoplastic resins or thermosetting resins, and is provided with a plurality of holes 3 that are adapted to allow the passage of water.
  • the holes 3 accommodate rubber nozzles, or the rubber nozzles are, as shown in the figures, arranged at a second plate-like element 4, which is adapted to be superimposed fully on the first plate-like element 2.
  • the plate-like element 4 completely covers the plate-like element 2 and is made for example of rubber or silicone.
  • a covering element 5 made of plastics, for example polypropylene, which is coupled to the plate-like element 2 by means of rivets 6 or any other suitable fixing means.
  • the covering element 5 is provided with a coupling 7 to which the pipe that conveys water to the cartridge, and therefore to the head, is connected.
  • the covering element 5 is provided with a water passage hole 8, around which the coupling 7 is connected. The water therefore passes between the covering element 5 and the plate-like element 4 or the individual nozzles that protrude from the holes 3 of the plate-like element 2.
  • the plate-like element 2 being made of plastic material, can have a very low thickness with respect to those made of metal.
  • stiffening elements associated with the plate-like element 2.
  • the stiffening elements can comprise at least one rib 10 provided on either face of the plate-like element 2 or on both of its faces, or a raised border 11 obtained on the outer perimeter of the plate-like element 2 or also a border that is associated with ribs 10.
  • the nozzles are designated by the reference numerals 9, and in this case are arranged at the lower portion of a plate-like element 4 made of rubber or silicone, as explained earlier.
  • the cartridge described above can then be inserted in a brass plate, which is suitably contoured and defines the body of the head, or in a head body that is made of plastic material and optionally chromium-plated.
  • the plate-like element 2 due to the extremely low thickness of the plate-like element 2 and of the two additional layers, i.e., the plate-like element 4 and the covering element 5, it is possible to provide a cartridge that has an extremely low thickness and therefore provide as a whole a head that has a reduced thickness, in order to provide a product that has a minimalist appearance, as required by the market.
  • the fact of providing all the components of the cartridge by using plastic material or rubber allows the cost of the cartridge according to the invention to be far lower than the cost of known types of cartridges that are entirely or partly made of metal.
  • the cartridge according to the invention fully achieves the intended aim and objects, since it allows to provide a shower head of extremely low thickness and at low costs.
  • the materials used may be any according to requirements and to the state of the art.
