Description

The invention relates to an easy-to-clean spray gun and accessories therefor.

Known spray guns consist essentially of a base body with handle and head and therein compressed air channels, a nozzle set, a compressed air connection, a trigger guard, an air duct system with an air valve, an air nozzle and a mechanism for adjusting the amount and pressure of the compressed air ducts flowing through air and a material guide system with a color needle and a mechanism for adjusting the amount of material. The spray gun head has a material-carrying region through which the material to be sprayed flows from a spray agent inlet to a spray agent outlet, which is generally configured as a material nozzle. At the spray inlet a material supply is provided, which may be present for example in the form of a reservoir or a supply of an external material storage. Typical storage containers are, for example, gravity cups, suction cups or side cups. The pressure difference can be generated, for example, by a material conveying device or by air flowing past an opening on the material supply. As spraying all flowable materials in question, for example, paints, coatings, adhesives or others.

The compressed air required for spraying is supplied to the air connection, which is arranged on or in the pistol grip. By operating the trigger guard up to a first pressure point of the air valve is opened. Upon further pulling the trigger guard, the paint needle is additionally pulled out of the spray nozzle. The spray then flows out of the material nozzle due to gravity, or a difference in pressure, and is atomized by the compressed air flowing out of the air nozzle.

Such spray guns have been proven over many decades in practice. The disadvantage, however, is that they require careful cleaning of the material-carrying areas after each use or before each material change, since otherwise it can lead to clogging of the areas and to contamination of the spray. This problem is solved according to the prior art in that the material guide is used as a cartridge, ie as a replaceable insert or interchangeable Sprühmittelleiteinrichtung, which is preferably designed as a disposable article. Such an advantageous spray gun with a holding portion and with a head, which is equipped with a cartridge, wherein the cartridge has an inlet region for a material-carrying channel, which ends in an outlet region and wherein the inlet region of the cartridge connected to a reservoir for the material to be sprayed or is connectable and wherein the cartridge preferably leads at least one material-carrying component of the pointed gun, is for example from DE 3016419 C2 known. This spray gun has a two-part head with a rear in the injection direction and a front in the spray direction area. The rear end of the front portion of the two-part head is provided with a plug-in seat for a cartridge having a spray-tube-extending tubular material-carrying channel, inside which a nozzle or paint needle is arranged. The nozzle needle can be reciprocated in the direction of the spray jet by means of a lever and spring mechanism so that the material to be sprayed can pass through a nozzle arranged in the outlet region for processing. The cartridge is held in the head by means of plug pin connections. After use, the pin connections can be solved, the two head areas folded against each other, the cartridge including the paint needle removed from the head and then thrown away. Thereafter, a new cartridge can be attached to or in the spray gun. Cleaning the material-carrying areas of the spray gun is unnecessary. However, the pin connections are relatively complicated, difficult to manufacture and solve and also do not always ensure the problem-free reliability.

Another spray gun with replaceable cartridge is in the DE 10 2004 027 789 A1 described. Subject of this publication is a two-part spray gun, wherein each of the two parts has a recess for receiving a replaceable Lackiermittelleiteinrichtung. The replaceable paint spray facility is inserted into the receptacle of the first gun part. Subsequently, the second gun part is placed on the first part and fixed with a screw. The commissioning of the spray gun is very tedious and time-consuming by this plurality of preparation steps. Next, the bipartite gun requires an immense extra effort in the production, since the two pistol parts are not identical and thus two production lines are required. This increases the manufacturing costs of the spray gun. The sealing of the gun cavities with respect to the outside air is difficult.

Another embodiment of a spray gun with replaceable cartridge is in WO 2009/015260 A2 disclosed. Again, the pistol consists essentially of two parts, a front and a rear part, which are connected by a hinge. To insert the cartridge, the front part is folded down, whereby the cartridge receptacle is exposed. After inserting the cartridge becomes the front part folded up again and connected by snap closure with the rear part. Although this allows a faster insertion of the cartridge into the pistol than in the previously described prior art, however, very high demands are placed on the quality of the hinge, in particular on its accuracy and strength. Thus, the production cost is very high compared to a conventional spray gun and it will cause significant additional costs in production.

An object of the present invention is therefore to provide a spray gun of the type mentioned, which is inexpensive to manufacture, which always works reliably and on or in particular a cartridge or other replaceable use less complicated, but securely attached and back from her or from her can be solved.

A further object of the invention is to provide a replaceable spray agent guide device which is suitable for use in connection with a one-piece spray gun according to the invention.

A further object of the present invention is to provide a material feeding device suitable for use in connection with a one-piece spray gun according to the invention and a replaceable spray medium guiding device according to the invention.

A fourth object of the present invention is to provide a lid which is suitable for use in conjunction with a one-piece spray gun according to the invention and a replaceable spray-medium guide device according to the invention.

The first object is achieved by means of a one-piece spray gun according to claim 1, which inter alia a base body, a trigger guard, coupled with the trigger guard paint needle actuator, coupled to the paint needle actuating element color needle and a replaceable Sprühmittelleiteinrichtung whose inlet region with a material feed device for the material to be sprayed or connectable, wherein the base body has a recess for receiving the replaceable Sprühmittelleiteinrichtung. The one-piece spray gun is characterized in comparison with the known prior art multi-part spray guns in that at least the main body of the gun consists of a single part. For inserting or removing the replaceable Sprühmittelleiteinrichtung no parts of the body must be moved, for example folded down or unscrewed, clipped, or glued. Attachments remain unaffected by this one-piece, d. H. the one-piece spray gun can several attachments such. As trigger guard, round / broad-jet regulation, locking screw, air micrometer, material quantity regulation or otherwise have.

The second object is achieved by means of an exchangeable spray medium guide device, which can be arranged in or on the one-piece spray gun. The exchangeable spray medium guide device is designed in such a way on the one-piece spray gun. The third object is achieved by a material feed device which can be arranged on the exchangeable spray medium guide device or on the one-piece spray gun or on both. The Materialzuführvorrichtung may be a flow cup, suction cup or side cup, or to a supply line with an external material storage such. B. a color, paint or adhesive container connected or connectable. As a result, the spray can be flowed or sucked directly from the material supply device into the exchangeable spray medium guide device or into the one-piece spray gun.

The fourth object is achieved by means of a lid which can be arranged on the replaceable spray medium guide device or on the one-piece spray gun or on both. The cover can be, for example, an air distributor ring or a nozzle set which can be screwed or otherwise arranged on the base body, for example by means of an air nozzle ring.

Advantageous embodiments are the subject of the dependent claims.

The one-piece spray gun may be configured for use with any liquid or aerosol, for example, for applying paint, paint or glue to objects.

The one-piece spray gun according to the invention has a recess which is designed so that it can receive an exchangeable spray medium guide device. In the case of operation, the replaceable spray medium guide device is supplied with a spraying agent via an inlet region. The spray flows through the interchangeable Sprühmittelleiteinrichtung to a paint outlet, where it emerges atomized after the nozzle under the influence of compressed air from the spray gun or is sprayed near the spray gun. The atomization can also be carried out by at least one electric field, by ultrasound, by high rotation or by another method or by a combination of several different methods. The inlet region of the exchangeable spray medium guide device can be connected or connectable to a Materialzuführvorrichtung. This may be, for example, at least a flow cup, suction cup or side cup, or a supply line with an external material storage such. B. a color, paint or adhesive container connected or connectable. A combination of these Materialzuführvorrichtungen is conceivable. Also, the material supply device may be connected not only to the inlet portion of the exchangeable spray medium guide device but also to an inlet portion of the base body which may be formed by the recess. The spray agent can then flow into the inlet region of the exchangeable spray medium guide device via this inlet region of the base body.

The replaceable Sprühmittelleiteinrichtung can be configured as a disposable part which is disposed of after use. For reuse of the spray gun, a new replaceable Sprühmittelleiteinrichtung is inserted into the recess of the spray gun. However, it is also conceivable to remove the replaceable Sprühmittelleiteinrichtung after use for cleaning purposes from the gun and then reinstate it.

Preferably, the recess is arranged on the upper side of the base body, laterally on the base body or on the underside of the base body. It is possible that the recess extends over several sides, is present on several sides, or extends from one to at least one other side. Thus, the spray gun can be predestined for various types of material feeders. A recess located at the top of the main body is to be provided in particular when the spray gun is to be used with a flow cup. A side recess allows the use of a side cup, a recess on the underside of the body is useful when using a suction cup. An external material supply device in the sense of a so-called kettle gun can be attached to any type of recess. With one or more recesses on different sides, it is possible to align the inlet region of the exchangeable spray medium guide device in different positions so as to be able to use different material feed devices with the same spray gun.

Preferably, the recess extends from a spray inlet to a spray outlet of the body. This makes it possible to convey the spray from a material feeder to the nozzle of the spray gun.

In a particularly preferred embodiment, the recess has at least one concave area. As a result, it is suitable for receiving a cylindrical, conical or tapered replaceable spray medium guide device.

Preferably, the at least one concave area. on its side facing the spray agent outlet, its side facing away from the spray agent outlet, opened downwards or upwards. Also, several open sides or oblique openings are conceivable.

Preferably, the at least one concave area at least partially has an opening angle of less than 180 ° and particularly preferably an opening angle of between 100 ° and 179 °. As a result, the exchangeable Sprühmittelleiteinrichtung is introduced with low elastic deformation in the recess, where it is held in a form-fitting manner without external force. By external force from a user, it can be removed again with little elastic deformation from the recess.

The recess may be configured such that the spray means can not be inserted into or attached to the base body by purely linear movement, or removed from it, but the insertion and removal movement must comprise at least one rotary component such as a pivoting movement. This has the advantage that the replaceable Sprühmittelleiteinrichtung is held without additional fixing means form fit from the body.

Preferably, the recess is formed in such a way that the replaceable Sprühmittelleiteinrichtung can be pivoted or inserted into the recess or by a plurality of superimposed or subsequent movements in or on the recess can be arranged.

The insertion of a replaceable Sprühmittelleiteinrichtung in a recess which is located at the top or on the underside of the body or laterally therefor, for example, proceed as follows: The interchangeable Spritzmittelleiteinrichtung with the Spritzmittelauslass the interchangeable Spritzmittelleiteinrichtung advance substantially coaxially with the recess axis (Spritzmitteleinlassachse) or parallel to this approached to the recess. If the spray medium outlet of the exchangeable spray medium guide device is approximately at the same height as the spray medium outlet of the base body, a swiveling movement takes place about the spray medium outlet of the exchangeable spray medium guide device coaxially with the spray medium outlet of the base body align. Subsequently, a displacement or insertion of the replaceable Sprühmittelleiteinrichtung done coaxially in the direction of the spray outlet of the body. To remove the replaceable Sprühmittelleiteinrichtung the steps are carried out in reverse order and in the opposite direction.

In a further embodiment of the one-piece spray gun according to the invention, in which the recess is located substantially laterally on the base body and extends to the top and / or the bottom thereof, the interchangeable spray medium guide device is inserted as described below: The exchangeable spray medium guide device is preceded by its spray agent outlet pivoted in the direction of the spray outlet of the body. The spray medium inlet of the exchangeable spray medium guide device is inclined relative to its proper orientation. Subsequently, the insertion process, a displacement or insertion of the interchangeable Spritzmittelleiteinrichtung include in the direction of the spray means outlet of the body, for example, until the interchangeable Spritzmittelleiteinrichtung rests at least partially on a contact area of the body or an attachment. The insertion process may further comprise folding the exchangeable spray medium guide device, in particular its spray agent inlet, into the position suitable for use. When using a flow cup, this is directed substantially upwards or obliquely upwards and in another direction. When using a suction cup or an external material feed device, the spray medium inlet of the exchangeable spray medium guide device is directed substantially downwards or obliquely downwards and in a further direction. When using a side cup, the exchangeable Sprühmittelleiteinrichtung can be pivoted from above or below and then folded in the lateral direction. It is in any case also possible that the recess is designed so that the interchangeable Sprühmittelleiteinrichtung can be pivoted from another side or from any page and then folded into the appropriate position.

The material supply device can either be attached to the replaceable spray medium guide device before the interchangeable spray medium guide device is introduced into the recess of the base body or thereafter. In the first case, the assembly consisting of the material supply device and the exchangeable spray medium guide device is arranged jointly in or on the recess.

The introduction of the paint needle can also be done before the onset of the interchangeable Sprühmittelleiteinrichtung or afterwards. It is conceivable that the paint needle is introduced into the replaceable Sprühmittelleiteinrichtung before it is arranged in or on the recess. Subsequently, the paint needle is connected via a coupling element with the paint needle actuating element releasably or permanently. The paint needle actuator can either be permanently in the spray gun or can be introduced before or after the insertion of the paint needle. It is also conceivable that the color needle is introduced only after arranging the replaceable Sprühmittelleiteinrichtung in this. This can be done together with the color needle actuator, when color needle and color needle actuator are assembled before insertion. Alternatively, the color needle can first be inserted into the replaceable spray medium guide device before the color needle actuation element is connected to the paint needle.

The paint needle can be arranged, for example by friction, in the replaceable spray medium guide device so that it presses against the outlet opening of the replaceable spray medium guide device even after removal of the replaceable spray medium guide device from the recess and thus closes it. As a result, the replaceable spray medium guide device can serve as a cup closure. Next closure means can thus be omitted.

The process of inserting and removing the replaceable Sprühmittelleiteinrichtung can in any case also include an operation of the trigger guard to move out, for example, the paint needle actuator from the path of the interchangeable Spritzmittelleiteinrichtung.

Preferably, the replaceable Sprühmittelleiteinrichtung is held by positive engagement, taper or tension in the recess. This allows a first fixation without further resources.

Preferably, at least one contact area in or on the recess provides for a radial and / or axial fixation of the exchangeable spray medium guide device in the recess. The abutment region may, for example, have a shoulder, a ring, a cone, a web, a hook and / or an eyelet which may be arranged on the replaceable spray medium guide device and / or on the main body. Furthermore, a contact element can be arranged on the exchangeable spray medium guide device and a counter element on the main body. The contact region can also be formed integrally with the base body and a Include sealing element or act as a seal and as a guide.

Preferably, the base body on one or more compressed air channels, which preferably extend in at least a part of the body, which has no recess. This allows compressed air to be routed from a discharge port to an air nozzle, regardless of the size, shape or location of the recess.

In a particularly preferred embodiment, the replaceable Sprühmittelleiteinrichtung is locked on at least one fixing means on or in the main body. This ensures, in addition to a first fixation, a secure hold of the replaceable spray medium guide device. The fixing means may for example comprise a mechanical, magnetic, pneumatic or hydraulic element. It may comprise a positive or positive connection, a film hinge, a latching mechanism, an eccentric element or a screw mechanism.

Furthermore, the exchangeable spray medium guide device can be fixable in or on the base body by means of the material feed device. This can be z. B. via bracing, d. H. the diameter of the spray medium inlet of the exchangeable spray medium guide device increases when attaching the material feed device, for example when screwing or screwing in or plugging in a cup, whereby the outer wall of the spray medium inlet of the exchangeable spray medium guide device is pressed against a region of the spray medium inlet of the base body.

Next, the fixation can be done by means of a cover arranged on the body or can be arranged in or on the body. By way of example, for this purpose, an air distributor ring or a nozzle set, which can be screwed or otherwise arranged on the base body by means of an air nozzle ring, may be mentioned. Also, this or these components may be designed as a disposable part for single use and be made of metal and / or plastic.

Magnetic elements may be, for example, magnets or magnetic tapes which are arranged or can be arranged on the exchangeable spray medium guide device and / or on the main body. In addition, it is conceivable that the replaceable Sprühmittelleiteinrichtung and / or the main body itself are magnetic or magnetizable or at least have corresponding areas.

At least one pneumatic and / or hydraulic element, for example a cylinder, a pneumatic muscle or an air cushion or oil cushion, can be arranged or arranged on the exchangeable spray medium guide device and / or on the base body and lock the replaceable spray medium guide device on the base body when it is activated.

The at least one pneumatic element can be connected or connectable to a separate compressed air supply. This may for example be a compressor which is connected via an air guiding device with the pneumatic element. In addition, in the field of compressed air supply or distribution or to a compressed air generator such as a compressor, a branch of the supply line may be provided, wherein a supply line, the compressed air channels and another supply line, the pneumatic element with air. The individual supplies may have common or separate means for adjusting the amount of air and / or air pressure.

Alternatively or additionally, the at least one pneumatic element can be connected to the same compressed air supply as the compressed air channels in the main body. This means that compressed air flows from a compressed air connection of the spray gun both into the compressed air channels in the main body and into the pneumatic element. The advantage of this embodiment is that the pneumatic element can be activated with only one compressed air connection, whereby the interchangeable Spritzmittelleiteinrichtung is locked. The pneumatic element can already be made activatable by connecting an air supply to the compressed air connection of the spray gun. Furthermore, the activation can be effected by actuation of the trigger guard or by means of a separate activation mechanism.

The replaceable Sprühmittelleiteinrichtung and the at least one fixing means may be formed either integrally or the interchangeable Spritzmittelleiteinrichtung may be releasably or permanently connected to the at least one fixing or connectable. For example, the fixing agent can be manufactured together with the exchangeable spray medium guide device, it can be injection-molded, glued, welded, soldered, clipped on or plugged on, fused on or otherwise connected or connectable.

In a particularly preferred embodiment, at least part of the paint needle extends through the exchangeable spray medium guide device. In order to prevent undesired escape of spray agent, at least one sealant may be arranged or arrangeable between the paint needle and the exchangeable spray medium guide device. This at least one sealant can with the interchangeable Sprühmittelleiteinrichtung or be connected to the paint needle or both. In the latter case, the sealant must be so large that a movement between the exchangeable Sprühmittelleiteinrichtung and the paint needle is possible. The at least one sealing means may be, for example, a molded sealing lip, a foil seal, a piercing membrane, a corrugated membrane, a bellows membrane, a sealing ring or another sealing means.

The paint needle can be configured in one or more parts and consist of a metal or a metal alloy and / or a plastic, a plastic mixture, a plastic alloy and / or a reinforced plastic or a plastic compound. The plastic may for example be reinforced with glass or carbon fibers, with other fibers or with particles such as nanoparticles, in particular carbon nanotubes. It is conceivable that different areas of the paint needle consist of different materials.

The color needle actuator may be releasably coupled to the paint needle or fixedly connected to the paint needle. The coupling can be done for example via a toothing, via a bolt coupling, via a ball coupling or via a prismatic coupling. Also combinations of different couplings are conceivable.

The color needle actuating element and the color needle can preferably be coupled to one another in a rotationally fixed manner, coupled, connected or connectable. A rotation of the components could make it difficult to remove the same or unintentionally release the clutch.

The replaceable Sprühmittelleiteinrichtung may be formed in one or more parts and consist of different materials. For example, the interchangeable spray medium guide device may be composed or manufactured from different metals and / or plastics. Different areas of the one-piece, as well as the multi-part interchangeable Spritzmittelleiteinrichtung may be colored differently. For example, the area through which the paint needle passes may be one color or transparent, while the spray inlet area may be a different color. The colors can be either already during the manufacturing process as well as added later or introduced or produced by in-mold labeling. In a preferred embodiment, different materials are at least partially colored differently. Thus, one plastic may have a different color than another plastic, one metal may have a different color than another metal, or a metal may have a different color than a plastic.

Advantages of the one-piece embodiment include a simple and inexpensive manufacture and the non-requirement of assembly.

The replaceable Sprühmittelleiteinrichtung may consist of at least two components that are releasably or permanently connected to each other or connectable. A component may be a functional component which has another function instead of or in addition to the spray agent guide. Such a function may, for example, be the locking of the exchangeable spray-medium guide device in the base body or the attachment of a material-feeding device to the interchangeable spray-medium guide device. It is also conceivable that one component is designed as a disposable article and another component is provided for repeated use. One component may be made of a harder and / or stronger material than another component. In particular, the needle-guiding region can be at least partially or in some areas harder or stronger than the spray-agent inlet region or vice versa. As a result, tribological, manufacturing or tolerance requirements can be met better or easier.

The replaceable Sprühmittelleiteinrichtung can have at least one releasably or permanently attachable nozzle. The nozzle is of paramount importance for the quality of the spray gun and the resulting spray result. Therefore, it must meet the highest demands on manufacturing tolerance and dimensional stability. It may thus be expedient to manufacture the nozzle separately and then attach it to another, less critical part of the exchangeable spray medium guide device. Furthermore, the use of different nozzle sizes is made possible by interchangeable nozzles. Preferably, the nozzle is made of a harder and / or stronger material than the first part of the exchangeable Sprühmittelleiteinrichtung. This makes it more dimensionally stable and less sensitive to the effect of force. Again, one part may be provided as a disposable article and another part for repeated use. Also, the one-piece replaceable Sprühmittelleiteinrichtung can be provided with a separate nozzle or be providable.

A part of the replaceable Sprühmittelleiteinrichtung may consist of an elastic or otherwise deformable material to him easier to use in the body can. It is conceivable that at least a part of the exchangeable spray medium guide device is designed to be inflatable. Thus, for example, it may be placed in or on the recess before being connected to an air supply. This air supply can be both a separate air supply, but it is also conceivable that the inflatable replaceable Sprühmittelleiteinrichtung is inflated by the air supply, which also supplies the spray gun with air. A combination of the two supplies is conceivable, for example, a separate Vorversorgung, which is maintained until the replaceable Sprühmittelleiteinrichtung by means of the air flowing through the spray gun is inflatable.

The replaceable Sprühmittelleiteinrichtung may consist at least of a first part which can be introduced into the base body in the region of the spray agent or can be arranged on this and a second part which can be introduced into the base body in the region of the spray medium inlet or at this. Thus, for example, a part can be introduced from the front through the spray agent outlet of the base body into this and another part from above through a spray medium inlet. The two parts can meet in one area and overlap and connect to each other.

As a result, a positive fit of the composite replaceable Spritzmittelleiteinrichtung is ensured in the body.

In the case of a multi-part replaceable spray medium guide device, at least one sealing means can be arranged or arranged in the connection region of the parts in order to prevent undesired escape of the spray agent.

In a preferred embodiment of the one-piece spray gun, the exchangeable spray medium guide device has at least one element for connection to a material supply device. As a result, the material supply device can be attached directly to the exchangeable spray medium guide device. A connection to the body can be omitted. The element may have at least one latching mechanism, at least one connecting rail, at least one thread or at least one thread segment. Alternatively or additionally, the replaceable spray medium guide device can be adhesively bonded, soldered, welded, attached or inserted to the material supply device.

The replaceable Sprühmittelleiteinrichtung can be connected to the Materialzuführvorrichtung and locked to it. However, it can also be fixed to the base body and connected only indirectly to the material supply device.

At least one sealing means, for example a sealing ring, can be arranged between the exchangeable spray medium guide device and the material feed device. However, the sealing can also be done by the material supply device and / or the interchangeable Sprühmittelleiteinrichtung, for example, if at least one of the two devices is made of a softer material, or by the connection between the two devices, for example by the thread.

The replaceable spray medium guide device and the material supply device can be formed in one piece. This is particularly advantageous if both the exchangeable spray medium guide device and the material feed device, for example a cup, are provided as disposable articles for single use.

If the exchangeable spray medium guide device is designed in several parts, a part of the exchangeable spray medium guide device can be detachably or non-detachably connected or connectable to the material supply device. The other part of the exchangeable spray medium guide device can in turn be connected or connectable to this connection.

The replaceable spray medium guide device may consist of a metal or a metal alloy and / or a plastic, a plastic mixture, a plastic alloy or a reinforced plastic or a plastic compound. Again, the plastic may be reinforced, for example, with glass or carbon fibers, with other fibers or with spherical or other shaped particles such as nanoparticles, in particular carbon nanotubes. Other reinforcements or stabilizations are possible.

The replaceable spray medium guide device preferably extends beyond the recess in the region of the spray agent outlet of the base body. As a result, a contact of the spray with the recess can be avoided whereby a cleaning of the recess can be omitted.

Alternatively, the replaceable Sprühmittelleiteinrichtung in the area of the spray agent outlet of the body before the recess or end with this.

Also in the area of the spray medium inlet of the base body, the exchangeable spray medium guide device can extend beyond the recess. For a connection of the replaceable Sprühmittelleiteinrichtung with a Materialzuführvorrichtung is better possible.

However, the replaceable Sprühmittelleiteinrichtung can also in the area of the spray agent inlet of the body before the recess or end with this. Thus, only a part of the recess needs to be cleaned after contact with a spray.

The recess may be designed to accommodate different size replaceable Sprühmittelleiteinrichtungen.

In a particularly preferred embodiment of the one-piece spray gun, at least one sealing means is arranged or can be arranged between the exchangeable spray medium guide device and the main body. As a result, an undesired material and / or air flow can be avoided and a tight fit of the exchangeable spray medium guide device in the recess can be ensured. The at least one sealing means can be arranged fixed or detachable on the exchangeable spray medium guide device or on the base body. In both cases, the at least one sealant may be molded or glued. Alternatively or additionally, at least one sealing means can be used loosely in at least one region of the recess.

The paint needle of a particularly advantageous one-piece spray gun is equipped with at least one return or actuating spring, which preferably extends within the exchangeable spray medium guide device. The spring may be supported on a stopper, which may be provided on the paint needle and integrally formed on the paint needle.

The feather ( 24 ) can be placed between the stopper ( 25 ) and a coupling element ( 5a . 5b . 51 . 52 . 53 ) can be arranged.

The stopper can be designed, for example, as a cone or as a disk and can be arranged inside or outside the exchangeable spray medium guide device.

In the recess 61b is an exchangeable spray medium ladder 27 used in the area of the spray inlet 600 and in the area of the spray outlet 700 of the basic body 1b over the recess 61b goes. The outlet area 27c the replaceable Sprühmittelleiteinrichtung 27 extends substantially to the outer end of the outlet of the air nozzle 11 , The exchangeable spray medium ladder 27 is held by a fixing means, not shown. Preferably, this is a film hinge whose one end with the interchangeable Spritzmittelleiteinrichtung 27 firmly connected, preferably molded, and the other end to the main body 1b is detachably connectable, preferably by a plug or clip connection. In the exemplary embodiment shown, essentially an entire lateral half of the recess serves as a contact area for the replaceable spray medium guide device 27 , As a result, a tight fit of the replaceable Sprühmittelleiteinrichtung 27 in the main body 1b guaranteed.

As in the first embodiment, the color needle 26 within the exchangeable spray medium guide device 27 arranged and is by webs 26a guided in it. For unconfirmed trigger guard 40 becomes the outlet area 27c the replaceable Sprühmittelleiteinrichtung 27 through the color needle 26 locked.

The spray medium conductor device 27 has a thread in the present as well as in the first embodiment 27a on, over which a material feeder 28 , in 6 a fluidly shown cup 28 , can be screwed on or screwed on. After screwing or unscrewing the filled with a spray fluid cup 28 to the replaceable Sprühmittelleiteinrichtung 27 the spray is running out of the gravity cup 28 in the inlet area 27b the replaceable Sprühmittelleiteinrichtung 27 in which it remains as long as the outlet area 27c the replaceable Sprühmittelleiteinrichtung 27 , which is configured in the present case as a nozzle, through the paint needle 26 is closed.

At the in 6 Roughly shown cup 28 are via predetermined breaking points closing elements 28a and 28b arranged. If the cup is not completely emptied after use, such an element may be broken off the cup and applied to the outlet portion of the cup to close it. Thus, the spray contained in the cup can be preserved for later use.

The closing elements 28a and 28b can be omitted if the interchangeable Sprühmittelleiteinrichtung 27 through the color needle 26 is closable, for example when the paint needle 26 due to friction in the outlet area 27c the replaceable Sprühmittelleiteinrichtung 27 is held.

7 shows a simple example interchangeable Sprühmittelleiteinrichtung 27 without details regarding fixing agent and coupling element. It is essentially constructed biaxial and consists of at least several composite cylinders, cylinder parts and cones. A part of replaceable spray medium conductor 27 that passes along an axis A is from the paint needle 26 penetrated. This part consists essentially of an elongate cylinder, another cylinder of smaller diameter and smaller length than the nozzle, which may also be in the form of a cone, and arranged between the two cylinders canoes through which the two cylinders merge into each other. Along an axis B, which meets the axis A at an angle which is preferably about 110 °, are two more cylinders which have similar diameter to each other which are larger than the diameter of the cylinder on axis A. The larger of the two cylinders preferably a thread through which a cup can be screwed. The thinner cylinder corresponds to a non-threaded connection of the cup and serves to further guide the same. Of course, all other types of connections are applicable. The cylinders of the axes A and B are connected via at least one asymmetric cone such that a spray from a cup on the cylinder of the axis B can flow as trouble-free as possible in the cylinder of the axis A. For mechanical support of the transition region between the axes A and B is a support element at a small angle between the axes 9 arranged in the form of a triangular plate.

The color needle 26 is via a coupling element 5 with the paint needle actuator 23 preferably releasably connected. The color needle actuator 23 has a stopper 25 on, in which one in the 7 to 10 not shown spring 24 is applied.

Of course, the interchangeable Spritzmittelleiteinrichtung 27 also consist of a larger or smaller number of cylinders and cones and other forms and combinations that can both stepwise and, for example, fluent merge into each other. The mechanical support may also have a different shape and be arranged on another side.

The fixation of such a simple replaceable Sprühmittelleiteinrichtung 27 in the main body can be done for example via a film hinge. One end of this can be done with the exchangeable spray medium guide 27 firmly connected, preferably molded, and the other end to the main body 1b be releasably connectable, preferably by a plug or clip connection

Building on this basic form of a replaceable Sprühmittelleiteinrichtung show the 8th to 10 Further developments of in 7 shown execution.

The in the 8th to 10 illustrated embodiments have a patch nozzle 8th on, which can be attached to the interchangeable Spritzmittelleiteinrichtung. The nozzle 8th For example, it may be mounted on the original nozzle, inserted into it, glued or otherwise attached thereto, but it may also be attached or attached to an exchangeable spray medium guide device originally designed without a nozzle.

At the in 8th The arrangement shown is the coupling element between the color needle 26 and paint needle actuator 23 in the form of a ball coupling 51 in front. One of the two parts to be coupled has a ball which can be inserted into a corresponding counter element such that the two elements are positively connected in at least one direction. In at least one other direction, the counter element is opened to allow easy release of the coupling. The fixing element 291 the replaceable Sprühmittelleiteinrichtung has a counter element 291a to intervene in the 1 shown groove 6d on. When inserting the replaceable Sprühmittelleiteinrichtung 271 in the recess 61a of the basic body 1a a spray gun snaps this counter element 291a in the groove 6d and fixes the exchangeable Sprühmittelleiteinrichtung 271 positive fit in the body 1a , To remove flexible areas of the fixing element are compressed, whereby the counter-elements 291a inside out of the groove 6d emerge and the replaceable Sprühmittelleiteinrichtung 271 release. This can then from the recess 61a be pulled out. Of course, the counter element 291a and the groove 6d be shaped differently, for example as hooks and eyes, and at another point of the recess 61a and the interchangeable Sprühmittelleiteinrichtung 271 be arranged. Also in the 1 to 3 illustrated basic body 1b can a groove for receiving the replaceable Sprühmittelleiteinrichtung 271 exhibit.

The coupling element in 9 consists in a bolt coupling 52 , On an element to be coupled are two bolts from the side, which can engage in a corresponding receptacle on the other element to be coupled. The fixative 292 the replaceable Sprühmittelleiteinrichtung 272 has a latching mechanism 292a on. It is a resilient region, the outer edge of which is at the same level with the outer edge of the replaceable Sprühmittelleiteinrichtung device when force 272 located. With unactuated resilient area is a step 292b , When inserting the replaceable Sprühmittelleiteinrichtung 272 in a recess, the resilient portion is pressed inwards. The recess is formed so that the resilient portion after the full insertion back to its original position and a step of the body at the stage 292b is applied and the replaceable Sprühmittelleiteinrichtung 272 fixed. The springy area has two wings which can be pushed inwards by the exchangeable spray medium guide 272 to be able to remove from the recess. Other latching and removal mechanisms are conceivable.

Another way to couple the color needle 26 with the paint needle actuator 23 is in 10 approachable. Here, the connection is made via a prismatic coupling 53 , The first half of the coupling element consists of a prism, which can be inserted from above into a corresponding counter element. The exchangeable spray medium ladder 273 has a fixative 293 with an eccentric element 293a , The eccentric element 293a can be over here in 10 invisible lever to be turned. When inserting the replaceable Sprühmittelleiteinrichtung 273 in the recess is the lever in the position that the narrow side of the eccentric element 293a pointing to the outside. After insertion, the lever is turned so that the wide side of the eccentric element 293a points outward and the interchangeable Spritzmittelleiteinrichtung 273 clamped in the recess.

Of course, the fixing element can also be configured differently, for example with a slider which clamps the replaceable spray medium guide device when inserted into slots on the fixing element. Combinations of different fixing elements are conceivable.

Substantially identical components, in particular the color needle actuating element 23 and the stopper 25 , are in the 7 to 10 provided with the same reference numerals.

It should finally be noted that the described embodiments describe only a limited selection of possible embodiments and thus represent no limitation of the present invention.
