Definitions

  • the present patent application for industrial invention relates to an improved WC cleaning brush.
  • a WC cleaning brush to clean a WC after use is known.
  • a WC cleaning brush is normally provided with a rod with handle and a brush (or similar cleaning part) fixed at one end of the rod.
  • DE29517960 discloses a cleaning brush provided with a pumping chamber with a a stem of a piston protruding in upper position in order to be actuated directly by the operator, in such manner to dispense the disinfecting liquid from nozzles disposed in proximity to the brush of the cleaning brush.
  • WO02/071907 discloses a WC cleaning tool comprising an elongated body with an inclined handle wherein a cartridge with disinfecting liquid is slidingly inserted. The cartridge is pushed downwards in order to dispense the disinfecting liquid from nozzles provided in the brush.
  • the purpose of the present invention is to remedy the aforementioned drawbacks by devising an improved WC cleaning brush that is versatile, practical and easy to use.
  • the WC cleaning brush of the invention comprises:
  • the peculiarity of the WC cleaning brush of the invention consists in that:
  • the advantages of the WC cleaning brush of the invention are evident.
  • the operator loads the tank with a disinfecting liquid and pushes the handle portion downwards, when the cleaning head is in contact with the WC wall, thus dispensing the disinfecting liquid from the nozzles provided in the cleaning head.
  • the WC cleaning brush of the invention is disclosed, which is generally indicated with reference numeral (1).
  • the WC cleaning brush (1) comprises a rod (11) with longitudinal axis (X-X).
  • the rod (11) comprises a handle portion (11 a) and a support portion (11 b).
  • a cleaning head (12) is fixed at one end of the support portion (11 b), in such manner to go in contact with the internal walls of the WC bowl.
  • the cleaning head (12) of the WC cleaning brush (1) is internally hollow and comprises a chamber (15) in communication with a plurality of nozzles (3) to deliver a disinfecting liquid.
  • the nozzles (3) are holes inside which bristles (S) are inserted, externally protruding from the cleaning head.
  • the WC cleaning brush (1) comprises a tank (2) containing disinfecting liquid.
  • the tank can be obtained in the handle portion (11 a).
  • the handle portion (11 a) is internally hollow and open on the back in order to fill the tank (2).
  • a cap (T) closes the back of the handle portion (11 a).
  • the tank (2) can be a cartridge disposed inside the handle portion (11 a).
  • the WC cleaning brush (1) comprises a pump (4) provided with a pumping chamber (40).
  • the pumping chamber (40) is joined to the handle portion (11 a) of the rod.
  • the pump (4) comprises an extraction opening (41) in communication with the tank (2) and a delivery opening (42) in communication with the nozzles (3).
  • the pump (4) comprises a piston (5) that slides inside said pumping chamber (40).
  • a stem (50) is fixed to the piston (5).
  • the stem (50) is internally hollow and comprises a channel (50b).
  • the delivery opening (42) of the pump is the end of the stem (50) disposed in the pumping chamber (40), while the extraction opening (41) is obtained at one end of the pumping chamber (40).
  • the stem (50) is connected to the support portion (11 b) of the rod.
  • the support portion (11 b) of the rod is internally hollow and provided with a channel (14) in communication with the chamber (15) of the cleaning head (12).
  • a connection pipe (80) connects the stem (50) to the support portion (11 b).
  • the support portion (11 b) is slidingly mounted with respect to the handle portion (11 a).
  • the piston (5) is moved in the pumping chamber (40), thus pumping the liquid from the tank (2) to the nozzles (3).
  • the WC cleaning brush comprises a guide sleeve (71) that protrudes axially from the handle portion (11 a) of the rod and the support portion (11 b) is slidingly mounted inside the guide sleeve (71).
  • Spring means (70) such as for example a helical spring, are disposed inside the guide sleeve (71) around the stem (50), between the handle portion (11 a) and the support portion (11 b) of the rod.
  • the pump comprises closing means (6), such as for example a ball shutter, disposed inside said pumping chamber (40) to close or clear the extraction opening (41) of the pumping chamber (40).
  • closing means (6) such as for example a ball shutter, disposed inside said pumping chamber (40) to close or clear the extraction opening (41) of the pumping chamber (40).
  • Elastic connection means (7) such as a helical spring, are provided to connect said closing means (6) to the piston (5).
  • the WC cleaning brush comprises blocking means (F) adapted to block the stem (50) of the piston when the closing means (6) close the extraction opening (41) of the pump.
  • the blocking means (F) comprise a metal ring (9) revolvingly mounted on the handle portion (11 a) of the rod.
  • the stem (50) comprises at least one tooth (51) that protrudes radially outwards from the stem (50).
  • the figures show two teeth (51) disposed in diametrically opposite positions.
  • the metal ring (9) comprises an annular seat (90) in communication with two grooves (91) ( Fig. 4 ) wherein the teeth (51) of the stem slide.
  • the rotation of the metal ring (9) blocks the tooth (51) in the seat (90) in bayonet coupling mode.
  • Fig. 2 shows the initial idle position of the WC cleaning brush (1), wherein the extraction opening (41) of the pump (4) is not closed and the pumping chamber (40) is in communication with the tank (2).
  • the pumping chamber (40) is filled with disinfecting liquid.
  • the piston (5) is in backward position with respect to the extraction opening (41) of the pump and the spring means (70) are not compressed.
  • the support portion (11 b) slides inside the guide sleeve (71) towards the handle portion (11a) and the spring means (70) are compressed.
  • the piston (5) slides inside the pumping chamber (40) towards the extraction mouth (41) of the pump.
  • the elastic connection means (7) are compressed and the closing means (6) close the extraction opening (41) of the pump (4).
  • the volume of the pumping chamber (40) is reduced and the disinfecting liquid contained in the pumping chamber forcedly enters into the channel (50b) of the stem through the delivery opening (42) of the pump. In this way, the disinfecting liquid flows towards the chamber (15) of the cleaning head (12) and is dispensed by the nozzles (3).
  • the spring means (70) are released, the piston (5) is moved back inside the pumping chamber (40) and the WC cleaning brush returns to the initial idle position, thus interrupting the distribution of disinfecting liquid from the nozzles (3).
