Abstract

A compressed-air-operated liquid spraying device comprises a liquid container (3), a conduit (9) emerging into the liquid container through one end thereof and adapted to convey the liquid from the container to a nozzle (8) through influence by compressed air. Said conduit emerges through said one end (10) thereof into a smaller liquid container (11) enclosed in said liquid container (3), having an opening (13) through which the conduit communicates with the larger, proper liquid container (3) and being arranged to function as a buffer by being, as the conduit, arranged to be filled with liquid through said opening and by that supply the quantity of liquid contained therein for spraying when the liquid spraying device is inclined away from a normal position in which the larger liquid container is located substantially under the nozzle.

Description

20 25 30 35 40 45 501 454 3- Uppfinningen kommer i det följande att närmare beskrivas genom utföringsexempel under hänvisning till bifogade ritningar, på vilken samma sifferbeteclcriingar i de olika figurema anger varandra motsvarande delar. 20 25 30 35 40 45 501 454 3- The invention will in the following be described in more detail by means of exemplary embodiments with reference to the accompanying drawings, in which the same numerical descriptions in the various diagrams indicate corresponding parts.

Fig 1 visar ett snitt av uppfinningen i horisontellt läge.Fig. 1 shows a section of the invention in horizontal position.

Fig 2 visar ett snitt av uppfinningen upp och ned.Fig. 2 shows a section of the winding up and down.

Fig 3 visar en konventionell färgspruta upp och ned.Fig. 3 shows a conventional spray gun upside down.

Fig 1 visar i en vätskespruta (1) ingående vätskebehållare (2) som inuti vätskebehållare (2) utrustas med en extra vätskebehâllare (3) som utgör en vätskebuffert.Fig. 1 shows a liquid container (2) contained in a liquid syringe (1) which is equipped inside a liquid container (2) with an additional liquid container (3) which constitutes a liquid buffer.

Vätskan (4) som fylls i vätskebehållare (2) sugs in i den extra vätskebehållaren (3) via filter (5). I sugledning (6) uppstår ett undertryck på grund av ejectorverkan som uppstår när trycklufi rusar genom ejectorventilen (7) i vätskesprutans handtag (8).The liquid (4) filled in the liquid container (2) is sucked into the auxiliary liquid container (3) via filter (5). In the suction line (6) a negative pressure arises due to the ejector action which occurs when pressure pressure rushes through the ejector valve (7) in the handle (8) of the liquid sprayer.

När trycklufien i ledning (9) rusar genom ejectorventilen (7) fås en medryckning av vätska i sugledningen (6) vilket medför att en luñ- och vätskeblandning fortsätter i ledning (10) vidare ut mot munstycke (11).When the pressure valve in line (9) rushes through the ejector valve (7), a entraining of liquid is obtained in the suction line (6), which means that a luñ and liquid mixture continues in line (10) further out towards the nozzle (11).

Så länge det finns vätska kvar i vätskebehållaren (2) kommer den extra vätskebehållaren (3) att vara helt fylld med färg.As long as there is liquid left in the liquid container (2), the extra liquid container (3) will be completely filled with paint.

När vätskebehållaren (2) vänds upp och ned, Fig 2, bildas en lufificka (12) i vätskebehållare (2).When the liquid container (2) is turned upside down, Fig. 2, a hatch (12) is formed in the liquid container (2).

Eftersom sugledningen (6) myrmar uti den extra vätskebehå1laren(3) kommer fortsatt vätskespridning att vara möjlig så länge det finns vätska kvar i den extra vätskebehållaren (3).As the suction line (6) murmurs in the extra liquid container (3), continued liquid spreading will be possible as long as there is liquid left in the extra liquid container (3).

I en konventionell vätskespruta, Fig 3, är sugledning (13) mycket längre än sugledning (6) i uppfinningen. För kort sugledning (13) innebär att en stor del av färgen skulle bli kvar i vätskebehållare (14) och antal päfyllningar av vätskebehållare (14) skulle öka.In a conventional liquid syringe, Fig. 3, the suction line (13) is much longer than the suction line (6) in the invention. Too short a suction line (13) means that a large part of the paint would remain in liquid containers (14) and the number of refills of liquid containers (14) would increase.

När en konventionell vätskespruta vänds upp och ned mynnar sugledning (13) ut i en lufificka (15) vars volym bestäms av vätskebehållarens (14) innehållande vätskevolym.When a conventional liquid syringe is turned upside down, the suction line (13) opens into a hatch (15) whose volume is determined by the liquid volume of the liquid container (14).

Spridning av vätskor med en konventionell vätskespruta vänd upp och ned innebär att lufi sugs med i sugledning (13) i stället för vätska. Detta förfarande ger ett icke önskvärt resultat på den yta som är föremål för vätskespridningen. Behållaren måste vändas i vertikalt läge för att ny färg skall tillföras munstycket varmed luftblandningen i färgen varierar under förloppet med ojämn kvalitet som resultat.Spreading liquids with a conventional liquid sprayer turned upside down means that the lid is sucked into the suction line (13) instead of liquid. This method gives an undesirable result on the surface which is subject to the liquid spreading. The container must be turned in a vertical position in order for new paint to be added to the nozzle, with which the air mixture in the paint varies during the process with uneven quality as a result.

Inom ramen för uppfinningstanken kan naturligtvis andra utföringsformer bli möjliga att tillämpa.Within the framework of the inventive concept, other embodiments may of course be possible to apply.
