Definitions

  • the invention relates to a compressed air operated cleaning gun with a Cleaning container containing detergent according to the preamble of the claim 1.
  • Cleaning guns For cleaning drain pipes, walls and the like Cleaning guns are used that have a pistol grip and a means of a hand lever have actuatable compressed air valve.
  • a cleaning gun can Have cleaning containers with a cleaning liquid from which by means of negative pressure the cleaning liquid is sucked in so that the compressed air mixes with the Cleaning liquid on a nozzle or an appropriately trained Outlet opening in the form of a cleaning jet emerges.
  • Achieving cleaning foam can be a fine mesh in the area of the outlet opening Sieve can be arranged, as is from German utility model 298 22 384 is known.
  • the known cleaning guns can only use liquids as cleaning agents use while pasty or thixotropic detergents in conventional Apply a brush or spatula to the surfaces to be cleaned must be applied.
  • Such viscous cleaning agents are particularly used to remove paint stains sprayed on walls.
  • the invention has for its object a compressed air operated cleaning gun to create with the viscous cleaning agent in the pressure spraying process surfaces to be cleaned can be applied.
  • the compressed air line extending in the nozzle tube of the cleaning gun can be on have a cross-sectional expansion at their front end, preferably in Form of an expansion nozzle, which in the area of cross-sectional expansion with Breakthroughs is provided.
  • a particularly suitable cleaning steel was used using a Expansion nozzle reached with the compressed air line via a connecting pipe piece was connected and a centering piece coaxially aligned towards the end had a larger inner diameter.
  • the connecting pipe section and in the ring wall between the connecting pipe piece and the centering piece were on the circumference distributed openings through which the viscous cleaning agent is optimal was sucked in.
  • a cleaning gun a 4cm to 10cm wider Cleaning jet of a cleaning mixture can be applied.
  • the Cleaning mixture is also like this due to the viscosity of the cleaning agent viscous that it sticks securely to masonry without dripping.
  • the cross-sectional expansion of the expansion nozzle preferably has one Outer diameter that corresponds to the inner diameter of the suction channel.
  • the cross-sectional extension forms a centering element with its front end, which the expansion nozzle and the pressure hose connected to it in the Centered suction channel.
  • the mixing space is preferably located in a on a base body Cleaning gun connected nozzle tube, which as well as the pressure hose can be removably attached to the base body.
  • the cleaning gun can be attached to the parts with the aggressive cleaning agent come into contact, be made of acid-resistant plastic, which However, the nozzle tube should preferably be made of stainless steel.
  • the cleaning gun 1 shown in Figure 1 is a compressed air-operated Cleaning device, which is not via a compressed air hose 2 to one here shown compressed air generator is connected.
  • a valve 4 is arranged which can be actuated via a hand lever 5. From the valve 4 extends a compressed air line 6 within a suction channel 7, which is in the front Area of the cleaning gun 1 leads into a nozzle tube 8.
  • a nozzle tube 8 At the front end of the Compressed air line 6 has an expansion nozzle 9 which is concentric in the nozzle tube 8 lies.
  • the expansion nozzle 9 encloses itself at a distance A.
  • Outlet section 10 whose inner diameter compared to the other Inner diameter of the nozzle tube 8 is expanded.
  • a cleaning container 11 is attached to the base body of the cleaning gun 1, in which is a viscous cleaning agent 12. Via a suction pipe 13 the cleaning agent 12 can be sucked into the suction channel 7.
  • the one for that required negative pressure is generated in the area of the expansion nozzle 9 in that compressed air expanding there at high speed into the mixing chamber 14 flows out, so that at the outlet opening 15 of the nozzle tube 8, a compressed air-cleaning agent mixture in the form of a slightly expanding beam emanates.
  • the compressed air supplied to the cleaning gun 1 is supplied by the Directional arrow 16 indicated.
  • FIG 2 is the front region of the nozzle tube 8, in which the Mixing chamber 14 is shown enlarged.
  • the expansion nozzle 9 protrudes a connecting pipe section 17 in the compressed air line 6 and has in the area of Connection pipe piece 17 openings 18.
  • the expansion nozzle 9 has in front area a cross-sectional enlargement 20, the outer diameter of which Corresponds to the inner diameter of the nozzle tube 8, so that the cross-sectional widening 20 forms a centering piece 21.
  • the annular wall 22 between the centering piece 21 and the Connector 17 is also provided with openings 18 so that the in Direction of arrow 23 flowing compressed air cleaning agent via the suction channel 7 from the Cleaning container 11 (Fig. 1) sucks.
  • the cleaning agent passes through the Openings 18 in the mixing chamber 14, where the compressed air-cleaning agent mixture forms.
  • the expansion nozzle 9 is preferably made of stainless steel as a rotationally symmetrical part made with openings 18, which are indicated by broken lines.
  • the in the drawing, the shape of the expansion nozzle 9 has a very high in experiments good suction power shown, so that thixotropic or pasty Detergent sucked in easily and with the cleaning gun Wall surfaces could be sprayed on specifically.
