Definitions

  • Devices for showers of the massage type are also known, in which a small disk, the rotation of which is caused by the flow itself, stops and starts the flow when rotating; the intermit­tent delivery thus carries out a kind of invigorating massage on the user's skin.
  • a disadvantage of such devices is that possible limestone infiltrations can easily block the disk. Furthermore, such devices do not carry out any skin oxygenation.
  • showers devices which comprise, in their handle, a single Venturi passage at which an inlet for a second fluid is provided (US 4.193.520) which fluid can be air (US 4.191.332).
  • US 4.193.520 which fluid can be air
  • this single Venturi is placed considerably far from the distribution section, and the plurality of jets necessary to the distribution is obtained by means of net like components, made of metal or plastics.
  • the jet obtained with such known devices does not carry out an effective hydromassage, since air and water mix together into a flow which is weak, rough and poor of kinetic energy; further air bubbles let into water are subject to crushing in the further path of the flow and when said flow is divided into jets, so that they arrive on the user's skin with poor effectiveness.
  • an hydromassage or water massage effect results from three elements: water pressure, temperature and amount of air mixed in the water.
  • a wrong calibration of such elements nullifies the desired effect.
  • the air bubbles flow must actually be mixed with the water flow, not simply added thereto.
  • the hydromassage results to be effective when the air violently moved by the water flow is subdivided into a lot of bubbles which break on hitting the skin, therefore releasing oxygen which assists the dilatation of the peripheral vessels. In this way, better and longer effects than the one obtained with a traditional massage are obtained and the continued use assists muscles invigoration, balance of tissues metabolism, a vasodila­tory action and an improvement of the peripheral blood circulation.
  • the aim of the present invention is to avoid the drawbacks of the prior shower distributors and to obtain a multiple jet having qualities suitable to carry out an effect hydromas­sage.
  • a distributing device comprising a head with several distributing holes, which is characterized in that at least some of the holes have a Venturi passage at their delivery outlet and, just downstream of said Venturi, an inlet duct for a second fluid, generally air, said duct communicating with a passage for said second fluid, having an adjustable opening.
  • the distributor comprises a body having tubular projections projecting inwards and defining the distributing holes, a nozzle- or injector-holder element, having nozzles co-operating with said tubular projec­tions so as to form Venturi passages therewith; and a cap having an air feed opening.
  • a chamber for water is defined between said body and said nozzle-holder element and a chamber for the second fluid, generally air, is defined between said nozzle-holder element and said cap.
  • the new shower distributor effects an hydromassage under optimum conditions; it is not liable to limestone deposits; it can be manufactured at low costs.
  • a shower distributing device generally refenced 10 in fig. 1 and 2, comprises a shower body 12, integral to a tubular handle part 13 with inner channel 14.
  • the body which is internally hollow, is provided with distribution or delivery openings 16, each one surround by a tubular part 17 extended inwards.
  • the insert 20 has a substantially cylindrical shape from which tapered wall nozzles or injectors 24 extend in a position corresponding to the cylinders 17 of the body.
  • a cap 26 is screwed on the insert 20 and has a lower cavity 27 and an upper cavity 27′, with an at least partially threaded wall, provided at the bottom with an abutment wall 28 at the sides of which through openings 29 are formed.
  • the plug 30 is movable on the threading between a lowered position against the wall 28, wherein it closes the hole, and various adjustably open positions.
  • a chamber 23 for air or other second fluid is formed between the cap 26 and the element 20.
  • a chamber 25 for water, in communication with the channel 14, is formed between element 20 and body 12.
  • Venturi is provided on each distribution hole and, for each distribution hole, at a fairly small distance "d" from the distribution or delivery section.
  • a preferred distance "d” is between 10 and 15 mm. It has been observed that in this way an air-water mixture with optimum features for an hydromassage is provided.
  • FIG. 1 A different embodiment of the distributing device is shown in figs. 3-5 and referenced 100.
  • the distributing device 100 in figs. 3, 4, 5 is screwed on the handle 113 having a water supply channel 114 and comprises a ring-shaped body 112, an annular nozzle holder element 120, an annular cover 126.
  • the body 112 has circumferentially spaced distributing holes 116, extended on the inside by tubular parts 117.
  • Element 120 has nozzles 124 at the holes 116.
  • An annular water chamber 125 is formed between parts 112 and 120, and is in communication with channel 114.
  • An annular chamber 123 for air or second fluid is formed between the element 120 and the closing ring 126 and is in communication with a part 129, the opening of which can be controlled by a slidable ring nut 130.
  • the air which is in chamber 123 is sucked in owing to the depression created in the Venturis 118 between the inner wall of the parts 117 and the nozzles 124.
  • a mixed air/water distribu­tion is provided from the holes 116.
  • a further embodiment of the distributing device is shown in figs. 6, 7, 8 and indicated with 200.
  • the device 200 comprises a ring-shaped body 212, an annular nozzle-holder element 220 and an anular cover 226.
  • the body and the nozzle-holder element are integral to a handle having a channel 214 for feeding water and a parallel channel 215 for feeding air or a second fluid.
  • the body 212 has circumferentially spaced distribution holes 216, which are internally and externally extended by tubular parts 217, 217′.
  • the nozzle-holder element 220 has nozzles 224 at the holes 216; a toric chamber 225 for water is formed between parts 212 and 220; a toric chamber 223 for air or second fluid is formed between parts 220 and 226, in communication with a port 229 communicating with the channel 215 and adjustable by means of a shutter 230 integral to a slider 231.
  • the air in the chamber 223 is sucked in through channel 215 owing to the depression created in the Venturi passages 218 between the inner wall of parts 217 and the nozzles 224.
  • the device 220 may be provided with a bush 250 on each nozzle, which acts as a flow guide or water guide, as well as with a top shell 252 and, if desired, with a pressure fitted removable distributor ring 260, having openings 262.
