Definitions

  • the invention is applicable to the field of accessories for machines for cleaning dirty surfaces; in particular it is preponderantly applicable for domestic use, such as for example cleaning car bodywork, or blinds and the like.
  • the devices are generally constituted by a handle for manoeuvring the brush and a box body which externally terminates with a plurality of soft bristles for cleaning a dirty surface.
  • the prior art includes an Italian patent, filed by the same application, no. IT 1214945, in which a washing brush is illustrated, activated by the cleaning water.
  • the device exhibits a tubular body, having a double function, as a handle for manoeuvring the brush and a port for connection to a water-supply source, defining a channel for water that terminates in a box-type body.
  • the body externally exhibits a plurality of bristles which, when the brush is moved about, eliminate the traces of dirt on a surface.
  • the use of the device includes a succession of operative stages before a clean surface is obtained.
  • a pre-washing stage in which he or she wets the dirty surface and, by brushing the surface with the bristles, effects a first cleaning operation on the surface.
  • the surface is rinsed, removing both the layer of detergent and the finer dirt.
  • brushes having an integrated reservoir for containing liquid detergent have been developed.
  • the reservoir is provided at a bottom thereof with detergent passage holes, which can also be termed mixing holes, which mix the detergent directly with water.
  • the pre-washing stage and detergent-distribution stage can be combined, simplifying the washing process by reducing working times.
  • the main aim of the present invention is to provide a brush integrated with a reservoir for liquid detergent which is not hampered by the above-described blocking problem of the mixing holes.
  • washing brush which is characterised in that it comprises one or more of the technical solutions claimed in the accompanying claims.
  • the washing brush ( 1 ) comprises a main body ( 2 ) having an inlet ( 3 ) connectable to a water supply source and an outlet ( 4 ) from which a mixture of water and liquid detergent exits externally of the brush ( 1 ).
  • the body ( 2 ) is provided with a reservoir ( 5 ) for containing a liquid detergent, having a bottom ( 5 a ) affording at least a hole ( 6 ).
  • the brush ( 1 ) is provided with integral means ( 9 ) for mechanically removing the liquid detergent remaining at the base of the at least a hole ( 6 ).
  • FIG. 1 is a section made along a horizontal plane of the device of the invention
  • FIG. 2 is a section made along line I-I of FIG. 1 of the device;
  • FIG. 3 is a detailed view from above of a first detail of the device
  • FIG. 4 is a detailed view from below of a second detail of the device.
  • 1 denotes in its entirety a washing brush according to the present invention.
  • the brush 1 is defined by a main body 2 exhibiting an inlet 3 which is connectable to a water supply source and an outlet 4 through which a mixture of water and liquid detergent terminates externally of the device.
  • the main body 2 is composed of a handle 25 connected to a box-type body 26 , which body 26 is preferably defined by an upper shell 26 a and a lower shell 26 b , joined one to the other.
  • the handle 25 which is preferably hollow and tubular, exhibits a first end 25 a which enables a connection of the inlet 3 to a water supply source and a second end 25 b which enables a connection to the box-type body 26 .
  • An attachment 27 is interpositioned between the body 26 and the handle 25 , in proximity of the second end 25 b of the handle 25 , which attachment 27 exhibits at a first end thereof 27 a , facing the inlet 3 , a filter 28 which can hold back solid substances suspended in the water, and at a second end thereof 27 b , opposite the first end 27 a , a nozzle 29 conveying the water flow.
  • the body 26 is inferiorly provided, at the lower shell 26 b , with a disc element 10 inferiorly provided with a plurality of bristles 7 for permitting a washing of a dirty surface.
  • Means for transmission of motion 8 are present internally of the body 26 , which means for transmission can induce a rotation on the disc element 10 .
  • the means for transmission of motion 8 exhibit a bladed impeller 13 and a sprocket 19 .
  • the impeller 13 and the sprocket are both keyed on a first shaft 14 by means of known type.
  • the impeller 13 exhibits a plurality of blades 18 on a periphery thereof, which are struck by the flow of water crossing the brush 1 .
  • the nozzle 29 of the attachment 27 causes the flow of water to converge on the plurality of blades 18 , inducing the impeller 13 to rotate.
  • the sprocket 19 is preferably located below the impeller 13 .
  • a reservoir 5 for containing a liquid detergent is located below the body 26 .
  • the reservoir 5 is defined by a recess 21 , preferably cylindrical and preferably afforded on the upper shell 26 a , which recess 21 functions as a bottom 5 a of the reservoir in which at least a hole 6 is afforded for expulsion of the liquid detergent.
  • At least five holes 6 are present, specially distributed on the circumferential periphery of the recess 21 .
  • an opening 22 is afforded on the lateral wall of the recess 21 .
  • the opening 22 is a port through which flows the water sent by the plurality of blades 18 of the impeller 13 internally of the reservoir 5 , so that the reservoir 5 also functions as a water-liquid detergent mixing chamber.
  • the reservoir is superiorly closed and sealed by a lid 23 .
  • the lid 23 inferiorly exhibits a prolongation 24 , preferably tubular and hollow and couplable with play internally of the recess 21 , which terminates with a regular toothing 31 defining a plurality of chambers.
  • the toothing 31 enables a gradual opening or closing of the opening 22 .
  • liquid detergent percolates, through the hole 6 , into the underlying zone to mix with the water turbulently internally of the body 26 .
  • more or fewer holes 6 on the bottom 5 a of the reservoir 5 can be opened or closed, to vary the quantity of water-detergent mixture exiting from the brush 1 , or only liquid detergent should the second embodiment be used.
  • the means 9 for mechanically removing comprise a disc element 10 and at least a projection 11 located on a back of the disc element 10 .
  • the disc element 10 which faces the reservoir and is below it, is inferiorly connected to the plurality of bristles 7 .
  • the disc element 10 is crossed by at least an opening 30 afforded thereon, which enables a mixture of water and liquid detergent to exit.
  • a toothing 20 is present on the periphery of the disc element 10 .
  • the toothing 20 is mechanically connected to the sprocket 19 , in such a way that the sprocket 19 transmits rotary motion to the disc element 10 , which in turn moves the plurality of bristles 7 .
  • the disc element 10 is superiorly connected to the at least a projection 11 .
  • the projection 11 preferably defined by a rectangular tooth 12 , extends from disc element 10 up until it contacts with the bottom 5 a of the reservoir 5 .
  • the tooth 12 when it rotates, being solidly constrained to the disc element 10 , drags on the bottom 5 a of the reservoir and describes a circular crown trajectory, interesting at least a hole 6 .
  • the means 9 for mechanically removing proceed to remove any traces of detergent remaining in the hole 6 which may have solidified.
  • the removal occurs through contact, but is also aided by an aspiration effect generated and amplified by the high speed of rotation of the disc element 10 .
  • the tooth 12 is preferably made of a synthetic material so that when dragging on the bottom of the reservoir 5 it does not cause any lacerations.
  • the means for scraping/dragging are composed of at least three teeth 12 .
  • Each tooth 12 of the at least three teeth has a different radial distance from the centre of the disc element 10 as the disc element 10 is arranged eccentrically with respect to the reservoir 5 .
  • a further advantage of the invention is given by an acceleration in the liquid detergent or water-detergent mixture exit, caused by the rapid passage of the teeth at the bottom orifice of the holes 6 .
  • This advantage also means that high-viscosity detergents can be used.
