Definitions

  • the invention relates to a compressed air-operated spray device for liquids, with a container for holding a liquid, a spray head connected to the container, a riser pipe connected to an outlet nozzle, which preferably extends to the vicinity of the bottom of the container, a closing valve arranged in the riser pipe, one Pump device for building up an increased air pressure in the container space above the liquid, a check valve between the pump device and the container which allows air to flow in the direction of the container, and means for actuating the closing valve and the pump device.
  • Such a spraying device is known from DE-C-906 200.
  • a pump device is assigned to this known device, which first allows an air pressure to be built up above the spray liquid in the container of the spray device. When a certain air pressure is reached, a spray valve can be opened with the help of a hand lever, through which the liquid is sprayed with the help of the air pressure.
  • the invention has for its object to provide a spraying device of the type mentioned, which allows to work over a longer period of time with a uniform spray pressure.
  • the spray device according to the invention is characterized in that a common pusher is provided as means for actuating the pump device and the closing valve, which actuates the pump device in the first part of its actuating stroke and switches the closing valve into the open position at the end of the actuating stroke.
  • a relatively high pressure can first be generated in the container space above the liquid via the first valve. If this high pressure is built up, the closing valve can be opened by further displacement of the pusher, so that the liquid present in the container can be sprayed through the outlet nozzle over a relatively long period of time.
  • the compressed air-operated spraying device shown in the figure comprises a container 1, which can be designed, for example, as a can and serves to hold a liquid 2, for example paint or oil and the like.
  • the liquid 2 fills the container 1 only to such an extent that a free space 3 remains above the liquid 2 in its upper region.
  • a nozzle 4 At the top end of the container 1 has a nozzle 4, on which a spray head 5 can be placed.
  • the spray head 5 has on its lower shaft side 6 an annular flange 7 which engages over the nozzle 4, so that a gas and liquid-tight connection between the container 1 and the spray head 5 is thereby produced.
  • sealing rings 8 can be located in the interior of the annular flange, which are pressed against the outer wall of the nozzle 4 when the spray head 5 is placed on it.
  • the end face of the connecting piece 4 opposite the lower shaft side 6 has two openings 9 and 10, through which a pressure supply pipe 11 and a riser pipe 12 each protrude. Both tubes 11 and 12 are firmly connected to the spray head 5.
  • the pressure supply pipe 11 projects so far beyond the lower shaft side 6 of the spray head 5 that it just extends through the upper end wall of the nozzle 4.
  • the pressure supply pipe 11 is not immersed in the liquid 2.
  • the riser pipe 12 below the lower shaft side 6 of the spray head 5 has such a length that it extends almost to the bottom 13 of the container 1.
  • the riser pipe 12 is connected to a filter 14, which prevents larger particles or assemblies from being transported upwards through the riser pipe 12, which would lead to the spray head 5 becoming blocked. So that after inserting the riser pipe 12 through the opening 10 of the filter 14 can be connected to the lower end of the riser pipe 12, the nozzle 4 can be removed from the container 1, for example unscrewed.
  • Air is conducted via the pressure supply pipe 11 into the free space 3 above the liquid 2 in order to build up an air pressure in the free space 3 which is greater than the ambient pressure outside the spray head 5.
  • the increased pressure in the free space 3 causes the liquid 2 to be pushed up through the filter 14 and then through the riser pipe 12.
  • the preferably rectangular spray head 5 has a pusher 15 on the shaft 5 a or leg connected to the container 1, which is located below the shaft 5 b of the spray head 5 lying horizontally in the figure.
  • the pusher 15 comprises a handle 16, which preferably has a plurality of concave recesses (not shown) on the outside, into which the fingers of a user using the spraying device can be inserted.
  • the grip strip 16 is connected to a guide rod 17 which can be moved back and forth in the axial direction within a guide channel 18.
  • the compression spring 19 causes the grip strip 16 to be moved back into its rest position after it has been actuated.
  • Guide rod 17, guide channel 18 and compression spring 19 are dimensioned so that a safe guidance of the handle bar 16 is possible.
  • those elements by which the grip strip 16 with the guide rod 17 and the compression spring 19 fall out of the guide channel 18 are not shown. These are generally known elements that can be used by the person skilled in the art if necessary.
  • the guide channel 18 preferably runs perpendicular to the outer wall of the shaft 5a and parallel to the horizontal shaft 5b and is designed as a cylindrical blind hole. Accordingly, the guide rod 17 has a circular cross section.
  • a pump rod 21 running parallel to the guide rod 17 is fixedly connected to the handle bar 16.
  • a piston 22 which can be pushed back and forth in a pressure cylinder 23 when the handle bar 16 is actuated.
  • the pressure cylinder 23 is also designed as a cylindrical blind hole, the opening of which lies on the side of the shaft 5a which is below the horizontal shaft 5b.
  • the pressure cylinder 23 is parallel to the guide channel 18.
  • Pistons 22 and pressure cylinders 23 preferably have circular cross sections which are coordinated with one another such that when the handle 16 is actuated, the air between the piston 22 and the rear end face 25 of the pressure cylinder 23 is compressed .
  • the piston 22 can also be covered with an elastic sealing plate 26 which, when the piston 22 moves in the direction of the rear end face 25, bears closely against the inner wall of the pressure cylinder 23.
  • the pressure cylinder 23 is connected to a pressure channel 27, which leads to the inlet of a first valve 28, the outlet of which is connected to the pressure supply pipe 11.
  • the first valve 28 is designed as a check valve and has a ball 31 located in a conical channel 29 in front of a channel opening 30, which ball is pressed against the edge of the channel opening 30 by a compression spring 32.
  • the conical channel 29, which opens in the direction of the pressure supply pipe 11, is formed by an annular element 33, which is located within a cylindrical chamber 34 within the spray head 5.
  • the compression spring 32 is supported on the ball 31 on the one hand and on the other hand on the wall of the chamber 34 from which the pressure supply pipe 11 branches off.
  • a second valve 35 is arranged inside the spray head 5 above the guide channel 18.
  • This second valve 35 is connected on the inlet side to the riser pipe 12 via a corresponding channel 12a running inside the spray head 5 and on the outlet side via a channel 12b likewise running in the spray head 5, to an outlet nozzle 36, the nozzle diameter of which is adjustable.
  • the second valve 35 is formed by a blind hole 37, which has likewise been introduced into the shaft 5a of the spray head 5 from the side of the grip strip 16 and which runs parallel to the guide channel 18.
  • This second valve 35 also has a ball 40 located in a conical channel 38 in front of a channel opening 39, which is pressed by a compression spring 41 against the edge of the channel opening 39.
  • an annular element 42 lies in the central region of the blind hole 37 and coaxially therewith, the central opening 39 of which is conically widened in the direction of the rear face 43 of the blind hole 37.
  • the blind hole 37 is divided into a first and a second valve chamber 44 and 45 by the annular element 42.
  • the first valve chamber 44 is connected to the channel 12a to the riser pipe 12 and the second valve chamber 45 to the channel 12b to the outlet nozzle 36.
  • Ball 40 and compression spring 41 thus lie in the first valve chamber 44.
  • the compression spring 41 is supported on the ball 40 on the one hand and on the other hand on the rear end face 43 of the blind hole 37.
  • the opening of the blind hole 37 located in the region of the grip strip 16 is sealed with a sealing element 46, which in turn has a central opening through which a switching rod 47 projects.
  • This switching rod 47 passes through the second valve chamber 45 and has one end within the channel opening 39, while the other end protrudes from the shaft 5a of the spray head 5.
  • the shift rod 47 is displaceable in the axial direction so that it can move the ball 40 against the force of the compression spring 41 in order to open the channel opening 39.
  • the axial displacement of the shift rod 47 takes place on the one hand with the aid of the grip bar 16 and on the other hand by the compression spring 41.
  • the length of the end of the shift rod 47 protruding from the shaft 5a is selected so that it is only then moved to the ball 400 by the grip bar 16 when the grip bar 16 has been displaced in the direction of the shaft 5a over a predetermined distance.
  • This predetermined distance can, for example, correspond to a desired stroke of the piston 22 in the pressure cylinder 32.
  • An annular end plate 48 can be arranged in front of the sealing element 46, the space between the sealing element 46 and the switching rod 47 being sealed by an additional sealing ring 49.
  • the shift rod 47 has, as is to be mentioned, a diameter which is smaller than the inside diameter of the channel opening 39, so that in the open state of the second valve 35 liquid through the space between the annular element 42 and the shift rod 47 into the second valve chamber 45 can occur.
  • the handle strip 16 is first actuated to generate a pressure in the free space 3 above the liquid 2 within the container 1.
  • the grip strip 16 is shifted one or more times by hand in the direction of the shaft 5a without it coming into contact with the shift rod 47.
  • the piston 22 is simultaneously displaced in the pressure cylinder 23, so that air is compressed by the pump device consisting of piston 22 and pressure cylinder 23.
  • the first valve 28 opens, so that the compressed air passes through the channel opening 30 and the pressure supply pipe 11 into the container 1.
  • the spray head 5 is preferably made of plastic, but can also be made of metal or another suitable material.
  • the spray head 5 can consist of a full plastic blank, in the chambers for the first and second valves 28, 35, a chamber for the pressure cylinder 23, the guide channel 18 and connecting channels 12b, 12a, 27 and 11 between the outlet nozzle 36 and the second valve 35 , second valve 35 and riser pipe 12, pressure cylinder 23 and first valve 28 and first valve 28 and bottom 6 of the spray head 5 are introduced.
