Definitions

  • the present disclosure relates to a cleaning tool. More specifically, the present disclosure relates to the cleaning tool which allows improved cleaning by easy and controlled delivery of a cleaning fluid.
  • a cleaning tool such as a cleaning gun uses high-pressure water spray to remove loose paint, mold, grime, dust, mud, chewing gum and dirt from surfaces and objects such as buildings, vehicles, and concrete surfaces.
  • the cleaning tool may allow power washing by taking advantage of the high-pressure water spray along with other features available with the cleaning tool.
  • a cleaning brush of the cleaning tool may have an integrated "cleaning jet" to previously spray the object to be cleaned with water, followed by washing off with clear water and the like.
  • an additional cleaning syringe may be needed.
  • a cumbersome change between the cleaning brush and the cleaning syringe may be necessary but undesirable for common users.
  • the entire cleaning brush, including handle and valve mechanism may need to be discarded. This makes the use of the cleaning tool more cumbersome in addition to high costs involved in their maintenance.
  • the '774 reference provides a fountain spray brush.
  • the fountain spray brush includes a U-shaped wire frame and bristles distributed along the frame. The ends of the frame are secured in a handle. Further, a spraying device extends from the handle.
  • the spraying device includes a tubular structure. The tubular structure is positioned axially between the arms of the U-shaped wire frame. The tubular structure includes perforations on the side wall suitable for delivering water to the bristles adjacent to it.
  • the spraying device is appreciably shorter than the frame by which it is enclosed and is provided with an axial opening at the extreme end suitable for delivering water to the bristles relatively remote from the spraying device at the end portion of the brush.
  • the '774 reference seems short of providing a simple, convenient cleaning tool which allows ease of water control along with other desired features.
  • the cleaning tool includes a housing having a first end and a second end.
  • the cleaning tool includes a liquid channel defined at the first end of the housing.
  • the liquid channel further defines at least one opening.
  • a plurality of cleaning elements of the cleaning tool are disposed around and at least partially enclose the liquid channel connected thereto.
  • the cleaning tool is characterized in that the cleaning tool is further adopted to have a nozzle coupled to the second end of the housing.
  • rotation of the cleaning tool when coupled to the nozzle, leads to rotation of the valve.
  • rotation of the cleaning tool includes rotation of the housing which leads to rotation of the valve of the nozzle. This may allow ease of rotation of the valve of the nozzle, which may allow change in water spray pattern from the nozzle. Further, the present disclosure may allow this rotation with a single-hand of users.
  • the nozzle is selectively fluidly coupled with the liquid channel and rotatable between a first rotational configuration and a second rotational configuration.
  • the nozzle allows a first fluid flow through the liquid channel in the first rotational configuration and a second fluid flow through the liquid channel in the second rotational configuration.
  • the first fluid flow and the second fluid flow may be one or more of a jet pattern, spray pattern, no flow, or any other fluid flow as per the application.
  • the liquid channel is defined as an elongated structure.
  • the liquid channel allows a better reach of the plurality of bristles associated with the liquid channel.
  • the housing is adapted to removably couple to the valve. This allows to switch between a hand brush and the liquid-based cleaning tool, by desired removal of the housing from the nozzle, as per the application.
  • each of the plurality of cleaning elements are bristles.
  • the cleaning elements may be bristles, foam brush, lips, and other cleaning elements as used or known in the art.
  • each of the bristles has a bristle opening and the liquid channel defines a liquid channel opening. Further, a diameter of the bristle opening of the bristles is greater than a diameter of the liquid channel opening. This results in pressure drop causing the water to flow almost without pressure and with improved control through the bristle openings.
  • the housing includes attachment portions.
  • the attachment portions allow removable coupling of the cleaning elements with the housing.
  • the cleaning elements are provided on a brush. This allows easy and removable coupling of the brush having the cleaning elements with the housing.
  • FIG. 1A illustrates a cleaning tool 100.
  • the cleaning tool 100 of the present disclosure is illustrated as a cleaning nozzle however the present disclosure may be readily applied with any cleaning tool such as a cleaning brush, a spray bottle, a cleaning gun and the like which helps in removing dirt, soil, loose paint, mold from surfaces of vehicles, buildings, furniture, and garden accessories.

  • the brush body 120 includes an internal regulation valve (not shown). A flow of fluid may be regulated by changing different configurations of the brush body 120. The configurational changes in the brush body 120 actuates the regulation valve. Further, the brush body 120 may indirectly actuate the nozzle 114.
  • the nozzle 114 is adapted to be rotated between a first rotational configuration R1 and a second rotational configuration R2.
  • FIG. 4A illustrates the first rotational configuration R1 of the brush body 120.
  • the first rotational configuration R1 of the brush body 120 is a clockwise rotation.
  • the nozzle 114 is selectively fluidly coupled with the liquid channel 108 such that the nozzle 114 allows the fluid flow through the liquid channel 108 in the first rotational configuration R1 of the brush body 120.

  • the nozzle 114 is selectively fluidly coupled with the liquid channel 108 such that the nozzle 114 stops the fluid flow through the liquid channel 108 in the second rotational configuration R2 of the brush body 120.
  • the needle 129 retracts. The fluid flow is made to stop on retracting of the needle 129.
  • rotation of the cleaning tool 100 when coupled to the nozzle 114, leads to rotation of the valve 160. More particularly, rotation of the cleaning tool 100 may include rotation of the housing 102 which leads to rotation of the valve 160.
  • the present disclosure thus allows rotation of the housing 102 with a single hand of users which lead to rotation of the valve 160.
  • the present disclosure mentions rotation of the nozzle 114, which actually pertains to rotation of the valve 160 of the nozzle 114 for desired change in flow of the liquid from the nozzle 114. This rotation of the valve 160. allows change in flow pattern (jet, sprinkler, and the like) through the nozzle 114.
  • the nozzle 114 is selectively fluidly coupled with the liquid channel 108 and rotatable between a first rotational configuration R1 and a second rotational configuration R2.
  • the valve 160 allows a first fluid flow through the liquid channel 108 in the first rotational configuration R1 and a second fluid flow through the liquid channel 108 in the second rotational configuration R2.
  • the first fluid flow and the second fluid flow may be one or more of a jet pattern, spray pattern, no flow, or any other fluid flow as per the application.

  • the convenient regulation of water volume may be done by one hand.
  • An arrow 138 is marked on the nozzle 114. The arrow 138 denotes that the flow of fluid may be increased on clockwise rotation and the flow of fluid may be decreased by anticlockwise rotation of the brush body 120.
  • torque transmission between the brush 110 and the brush body 120 may be actuated by adherence, positive fitting or any other transmission technique as used or known in the art.
  • the configurational changes may be brought by rotation, sliding, or by switching on/ off a button if provided with the brush body 120.
  • FIG. 5 illustrates the liquid channel 108 having the liquid channel opening 132.
  • the present disclosure illustrates the liquid channel 108 as substantially cylindrical shaped and the liquid channel opening 132 defines its diameter.
  • the sum of all bristle openings 130 have diameter greater than diameter of the liquid channel opening 132. This results in pressure drop of the liquid entering the liquid channel 108 at its channel opening 132, thus the force on the connection of housing 102 and the brush 110 is significantly reduced.
  • a positive connection is created by the engaging seats 142 and inner ribs 143, as best illustrated with reference to FIGS. 2A , and 5 . Further, this connection between the engaging seats 142 and inner ribs 143 allows desired coupling of the housing 102 and the nozzle 114, respectively. Then, any rotation of the housing 102 allows rotation of the valve 160 of the nozzle 114, which allows desired change in flow of the liquid from the nozzle 114. Alternatively, rotation of the nozzle 114 may allow rotation of the housing 102.
  • the diameter of the liquid channel opening 132 is greater than a diameter of a water ring 133.
  • This arrangement provides that the diameter of the bristle opening 130 of the bristles 112 is greater than a diameter of the liquid channel opening 132, which is greater than the diameter of the water ring 133.
  • This arrangement ensures that there is drop of pressure in flow of the water flowing from the nozzle 114 to the housing 102. Moreover, this pressure drop from the water ring 133 to the liquid channel opening 132 and then to the bristle opening 130 of the bristles 112 allows to avoid any inadvertent disassembly of the nozzle 114 and the housing 102.
  • the bristle openings 130 and the liquid channel openings 132 may have different dimensions, different shapes to cause pressure drop. Additionally, or alternatively, the bristle openings 130 and the liquid channel openings 132 may have same dimensions which even provide pressure drop in one way or the other. Such as, the bristle openings 130 and the liquid channel openings 132 both are large enough to allow the best pace of the fluid to come out.
  • FIG. 6 illustrates the liquid channel 108.
  • the liquid channel 108 includes an integrated reservoir 134.
  • the integrated reservoir 134 may be for chemical cleaning additives such as soaps, barnacles and the like.
  • a soap stick 136 may be kept.
  • the soap stick 136 may be substituted by any detergent.
  • the integrated reservoir 134 for the soap stick 136 provides the cleaning tool 100 with an additional benefit.
  • the integrated reservoir 134 provides an optional use of the soap stick 136 as per the requirements. As bicycles, car rims, garden furniture and the like may be immaculately cleaned by the active actions of the soap stick 136.
  • an external holder may be provided with the cleaning tool 100.
  • the external holder may carry soap, detergent and any such chemical cleaning additive.
  • the external holder may be provided near to the liquid channel openings 132. This allows mixing of incoming water with the detergent before falling on the surface of the object to be cleaned.
  • the integrated reservoir 134 may have an external button, switch provided with the cleaning tool 100 which may allow mixing of water with the detergent on demand of the user.
  • the present disclosure also allows application of the brush 110 and the nozzle 114 individually and separately, as illustrated in FIG. 7 .
  • the nozzle 114 may be disassembled from the grimy, soiled brush 110 so as to clean the brush 110 by a water stream W of the nozzle 114.
  • detachable arrangement of the brush 110 and the nozzle 114 also allows ease of replacement, such as replacement of the nozzle 114 or the brush 110 after service life or for other applications considerations.
  • the present disclosure provides the cleaning tool 100, which is simple, cost-effective, and multi-purpose.
  • the cleaning tool 100 may be readily switched between a cleaning syringe (i.e. the nozzle 114) and washing brush (with the brush 110). Further, the application of the brush 110 may be easily performed with a simple click-action. Further, the cleaning tool 100 allows ease of rotation of the cleaning tool 100 (say the housing 102) by a single hand of the users leading to desired change in liquid flow from the nozzle 116.
