Definitions

  • the present invention concerns a water spraying device, particularly an oxygenating or water-air mixing shower with self-cleaning spout features, that can be hold in a hand or connected to a shower holder in an overhead position in a shower cabin or bathroom or installed in a bathing equipment.
  • showers or more specifically shower heads are widely used in a variety of bathing places. There are known three types of showers:
  • the water from the existing water pipes contains impurities which inevitably accumulate in the shower and obstruct the spout holes after some time of use. Removing these impurities and incrustations from the spout holes of a shower, particularly from an overhead shower is very difficult annoying and requires removal or unmounting of the entire overhead shower.
  • the present invention provides a preferably oxygenated or air water mixing overhead shower with self-cleaning spout holes.
  • the object of the present invention is to provide a shower having features to obviate the drawbacks cited with respect to the prior art.
  • the invention aims to enable automatic removal of the dirt and impurities in the spout of a shower.
  • a self-cleaning overhead shower comprises:
  • the shower of the present invention takes full advantage of the water pressure and elastic force of the spring, and cleaning is automatically carried out upon turning on and off the water supply, thus avoiding spout blockage due to the accumulation of impurities and obviating troublesome cleaning of the shower.
  • the shower has a simple structure and is easy to install. There are no demanding requirements for the size and shape of the structural parts, and its manufacturing is thus simplified.
  • a preferably but not necessarily oxygenated overhead shower with a self-cleaning spout comprises a fixing base 2, a shutter 3, a spring 4, a water distribution part 5, a surface cover 6, a gasket 7 and a main body 8.
  • the fixing base 2 and the main body 8 are locked together to form a containing chamber 11, and the shutter 3, the spring 4, the water distribution part 5, the surface cover 6 and the gasket 7 are arranged in the containing chamber 11.
  • the surface cover 6 comprises or forms a spout 61 and a supporting column 62 protruding from the spout 61.
  • the water distribution part 5 comprises or forms a through hole 52 and one or more cleaning pins 51 positioned in alignment with the spout holes of the spout 61.
  • the supporting column 62 of the surface cover 6 extends through the through hole 52 of the water distribution part 5 and is fixed to the shutter 3, in a manner that the surface cover 6 is movable with respect to the water distribution part 5.
  • the cleaning pin or pins 51 of the water distribution part 5 is inserted or protrudes into the spout holes of the spout 61 of the surface cover 6.
  • the surface cover 6 drives the spout 61 to detach the spout hole or holes from the cleaning pin or pins 51, and the shower sprays water through the spout holes of spout 61 to the outside.
  • the surface cover 6 drives the spout 61 to reset (to move back in a rest position) whereby the cleaning pin or pins 51 of the water distribution part 5 automatically penetrate the (spout holes of) the spout 61 of the surface cover and remove dirt and impurities accumulated therein.
  • the spring 4 is installed on the supporting column 62 of the surface cover 6, with a first spring end abutting against the shutter 3, and a second spring end abutting against the water distribution part 5, thereby biasing the spout 61 of the surface cover 6 permanently elastically towards the water distribution part 5.
  • the supporting column 62 of the surface cover 6 may be fixed to the shutter 3 by a variety of different connecting means.
  • the supporting column 62 of the surface cover 6 may have a hollow, e.g. threaded tube shape, and the shutter 3 may have a, e.g. flange shaped pressing part 31 and a, e.g. threaded tubular, fixing part 32.
  • the threaded portion of the hollow supporting column 62 of the surface cover 6 may be thread connected with the fixing part 32 of the shutter 3 so that the (e.g. flange shaped) pressing part 31 of the shutter 3 presses against (e.g. the free end) of the supporting column 62.
  • the shower may further include a ball joint 9, an air intake insert 91 and a waterproof O-ring 92.
  • the air intake insert 91 and O-ring 92 are arranged in the ball joint 9 and form together an air intake assembly.
  • the ball joint 9, air intake insert 91 and O-ring 92 define together an air chamber 12 around the air intake insert 91.
  • the ball joint 9 forms air inlets 93 which allow air to be sucked from an outside of the ball joint 9 to its inside, particularly into the air chamber 12.
  • the air intake insert 91 forms a Venturi type channel and one or more secondary air inlets 13 extending through a side wall of the air intake insert 91 from the air chamber 12 in the Venturi type channel, so that a water flow through the Venturi-type channel will generate a pressure gradient which sucks environmental air through the air inlets 93 of the ball joint 9, the air chamber 12 and the secondary air inlets 13 into the Venturi-type channel inside the air intake insert 91 and mix the sucked in air into the water flow to increase its oxygen content, which is beneficial to the bathers health and helps saving water.
  • the Venturi-type channel of the air intake insert 91 may form narrow orifices 911 adapted to accelerate a water flow therethrough and, downstream of the narrow orifices 911, an expansion and mixing space 14 having a greater flow section than the narrow orifices 911 and into which the secondary air inlets 13 open.
  • the ball joint 9 may be fluid connected and fixed to the fixing base 2 by means of a connecting nut 1.
  • the connecting nut 1 may have an annular flange portion and a tubular wall portion connected thereto.
  • An inner surface of the tubular wall portion of the connecting nut 1 may form an internal thread which can be screw connected with a corresponding external thread formed on an external surface of a tubular mounting seat 21 of the fixing base 2.
  • the ball joint 9 extends through the connecting nut 1 and is rotatably received in the mounting seat 21 of the fixing base 2 so that and the air inlet 93 of the ball joint 9 is exposed outside the connecting nut 1.
  • the connecting nut 1 is screw connected with the mounting seat 21 of the fixing base 2, thereby restraining the ball joint 9 in the mounting seat 21 of the fixing base 2 and allowing adjustment of the water outflow angle of the overhead shower.
  • a ring-shaped gasket 7 can be interposed between the main body 8, the fixing base 2, the distribution part 5 and the surface cover 6 to achieve water tight sealing therebetween.
  • the gasket 7 may have a "Z" shaped or a "C” shaped cross-sectional shape. More particularly, the gasket 7 can form an upper flange 71 and a lower flange 72 connected by a ring wall 73, wherein a bottom surface of the upper flange 71 abuts against the main body 8, a top surface of the upper flange 71 abuts against the water distribution part 5 and the fixing base 2, so that the upper flange 71 is sealingly clamped between the water distribution part 5 and the fixing base 2 from above and the main body 8 from below.
  • a bottom surface of the lower flange 72 abuts (with an underside thereof) against the main body 8 and the surface cover 6 is arranged to abut against (and sealingly clamp the lower gasket flange 72 between the surface cover 6 and the main body 8) and detach from the a top surface of the lower flange 72 in a movable manner, such that, when water flows through the shower, the surface cover 6 abuts against the top surface of the lower flange 72 of the gasket 7 and, when the water supply is turned off, the surface cover 6 detaches from the top surface of the lower flange 72.
  • the shower adopts mechanical or hydrodynamic sealing and automatic sealing can be achieved in dependency of the water pressure acting on the components of the shower.
  • the gasket 7 can also adopt other shapes, as long as it can maintain the water tightness of the overhead shower.
  • the fixing base 2 forms a, preferably but not necessarily dome-shaped, cavity 22 facing the shutter 3 and adapted to define together with the shutter 3 a pressure chamber.
  • the dome-shaped cavity 22 maintains the pressure chamber 15 space comparatively small so that a water pressure can be built up inside the pressure chamber 15 more easily and without any need of any additional devices.
  • the shutter 3 When the shower is in its initial state, the shutter 3 abuts against the fixing base 2 due to the elastic force of the spring 4, and the surface cover 6 (which is screwed on the shutter 3) is elastically hold against the water distribution part 5, so that the cleaning pin or pins 51 of the water distribution part 5 penetrate into the spout holes of spout 61 of the surface cover 6.
