Description

The technical field to which the utility model relates.

The utility model relates to coloring devices with the application of active powders with a binder or film former on the surface of products, in particular to spray guns with airless spraying of paints and film former.

State of the art

An analogue of the utility model is a spray gun that is widely known in the art [1]. Due to the ejection effect, air in the spray guns draws in a liquid, powder or suspension and then sprays it onto the surface to be treated (for example, to be painted). The disadvantage of the analogue is that the spray gun needs an air source (for example, a compressor) with a certain pressure at a certain flow rate and is mainly used as a means of applying liquid paints to painted surfaces.

An analogue of the utility model is also the well-known nozzles on standard spray cans with paint in the form of a pistol grip, sometimes also called the “spray can handle” or “spray can applicator” [2, 3]. The nozzle is put on an aerosol can, and the pressure part of the trigger of the pistol grip has the ability to act on the pressure cap-spray of the aerosol can when the user presses the trigger. This nozzle is designed to increase ease of use without contaminating the user with paint, which inevitably falls on the user's thumb, acting on the pressure cap of the spray bottle when painting surfaces. A disadvantage of the analogue is the inability to apply a film former with powdered substances on the treated surfaces, which are necessary for the consumer to introduce into the film former.

As a prototype of a utility model, the installation of applying powder mixtures on the surface [4] manufactured by CJSC Tsentroenergoteploizolyatsiya was selected, in which liquid glass, diluted to the desired consistency, or some other bundle is supplied from the reservoir under pressure of compressed air through a hose to the spray gun and upon exiting the nozzle of the gun, it moistens a powder heat-insulating mixture of asbestos with perlite, which is also supplied to the nozzle by ejection using compressed air pressure, turning it into an adhesive mass that adheres to the insulator surface to be washed.

The disadvantages of the device of the prototype are high weight and size characteristics, the need to supply the device with compressed air from the overall compressor or the pneumatic network, the complexity and inconvenience of maintenance.

The purpose of the claimed utility model is the creation of a portable and not requiring external energy sources device for applying active powdery substances, including microsphere powders, onto painted surfaces.

This goal is achieved by the fact that the spray nozzle on the aerosol can with a foaming agent in the form of a pistol grip with a trigger has a powder container holder with a powder container and at least one passage from the powder container to the metering shutter, and also a metering shutter with at least one passage opening connected to the trigger.

An additional feature of the spray nozzle is that said powder container holder and said metering slide have magnets mounted to be attracted to each other.

An additional feature of the nozzle-spray gun is that the said powder container has a predominantly spherical shape.

An additional feature of the nozzle-spray gun is that the said powder is a microsphere filled with a fire extinguishing agent.

Utility Model Disclosure

The utility model is illustrated by drawings, which depict:

FIG. 1 - Spray gun assembly with an aerosol can.

FIG. 2 - Nozzle-spray gun before starting work: scheme-section.

FIG. 3 - Spray gun during operation: sectional diagram.

FIG. 1. The nozzle-spray gun consists of a standard aerosol can 1 with paint or varnish (film former), a removable nozzle for the aerosol can in the form of a pistol grip 2 with a trigger (hook) 3, holder 4 of the powder container 5, and a shutter-dispenser 6.

FIG. 2. In the state prior to the start of operation of the nozzle-spray gun, the shutter-dispenser 6, having a magnet 7 (for example, a neodymium magnet “countersink disk”) with a through hole 8 and a through cone 9, is attracted to the magnet of the same type (or another shape), fixed in the holder 4 of the powder container, while blocking the inner generatrix of the passage cone 9, the passage hole 11 made in the holder 4 and communicating with the powder container 5. The powder does not have the ability to fall out of the powder container 5.

FIG. 3. When the trigger 3 is pressed, its part 12 presses the spray cap 13 of the aerosol can 1 and at the same time the cone 9 of the shutter-dispenser 5 connected to the trigger 3 and lowering, overcomes the attraction of magnets 7 and 10. The magnets come off from each other friend, while the passage cone 9 opens the passage hole 11 for free passage of the powder 14 from the powder container 5 to the passage hole 8. The powder 14 from the powder container 5 begins to precipitate into the jet of aerosol formed in the spray cap 13 through the passage hole Grade 8 is picked up by the jet, at the same time mixing with the aerosol and forming a homogeneous aerosol-powder mixture, which reaches the surface to be treated, forming a coating from the film former and the powder mixed with it. The movement of powder and aerosol is shown by arrows. In the resulting coating, the powder particles are evenly distributed in the coating area, forming upon drying or polymerization of the film former a colorful or varnish layer with particles of the active powder. As an active powder, a fire extinguishing powder is predominantly used, consisting of microspheres with a diameter of 0.01 mm to 1.0 mm, for example, extinguishing microcapsules "FOG" of the company "RUSINTECH" [5], which disintegrate in the fire source with the formation of free radicals, breaking off kinetic chains of the combustion process, stopping its development within a few seconds.

It should be noted that in the proposed device can be made not one, but several through holes 8 and 11.

The proposed nozzle-spray gun is a portable and stand-alone device for treating surfaces with active powders, which does not need additional energy sources for transporting the powder to the spray part of the film former, as well as the presence of a compressed air source or pumping equipment for spraying the film former itself.
