Description

The inventive utility model relates to a device for supplying aerosol contents by means of gas pressure from the inside, and more particularly, to spray heads used in mounting guns, applying a pressurized aerosol substance in a contact manner in the form of jets and / or sprays applied to various surface.

Known spray nozzle comprising a housing with a base made in the form of petals protruding oppositely behind the housing’s dimensions and with a through step hole, at the outlet of which there is a nozzle with beveled walls expanding towards the sprayed medium, plate projections placed opposite each other, the fastening means, the nozzle is made in the form of an oval with a ratio of length to width of 1.4-1.8 (1).

A disadvantage of the known technical solution is the relatively low performance, as well as the impossibility of its use for polyurethane compositions of high viscosity.

A disadvantage of the known technical solution is the lack of a description of the proper attachment of the nozzle to the cylinder of the polyurethane insulation foam.

The closest is a device for spraying a medium under pressure by gas pressure from the inside, and more specifically, to spray heads used in mounting guns, applying a pressurized aerosol substance in a contact manner, in the form of jets and / or sprays applied to various surfaces . The spray nozzle is equipped with a means of its fastening in its non-operational position (2).

The known spray nozzle of an assembly gun for controlled aerosol spraying of a polyurethane medium under pressure comprises a cylindrical body provided with a base at the first end with a landing hole extending inside the said cylindrical body, forming a cavity in it for accommodating the gun barrel attached to the container. The container contains an aerosol composition.

A disadvantage of the known technical solution is the limited range of applications, since the application of the aerosol composition is possible only on the surface in an upright position.

The objective of the claimed utility model is to improve the performance of a device for spraying a medium under pressure.

The technical result consists in the creation of a device for supplying aerosol contents by means of gas pressure from the inside in mounting guns, which distribute the pressurized aerosol in a contact manner in the form of jets and / or sprays applied to various surfaces, both in vertical and horizontal position.

The problem is achieved in that the spray nozzle of the mounting gun for controlled aerosol spraying of the polyurethane medium under pressure contains a cylindrical body provided with a base from the first end with a base hole extending inside the said cylindrical body, forming a cavity in it for accommodating the gun barrel attached to the tank. The container contains an aerosol composition. The spray nozzle is equipped with a means of its fastening when it is not in use.

The spray nozzle comprises a spray gun and an adapter, which have a cylindrical body. The inner part of the sprayer is made in the form of a through hole at the outlet of the sprayed medium and is communicated through an adapter with a through hole of the gun barrel. A thread is made on one side of the spray gun at the junction with the adapter. In the upper part of the atomizer around the through hole at the outlet of the sprayed medium, an elevation of a cylindrical shape with a through hole having a slit-like shape is made. The adapter has two parts with a larger diameter on the outside and a smaller diameter on the other side at the junction with the spray gun. A thread is made in the adapter at the junction with the spray gun. On both sides of the adapter there are two protruding ribs located opposite each other. In this case, the spray gun with the adapter is attached to the means for mounting, made in the form of a “bracket”.

The adapter has a bend in the middle, and the threaded part is located at an angle to the landing part of the adapter. On both sides of the adapter are two ribs located opposite each other, with one of the ribs above the bend, and the other below. The atomizer with the adapter is attached to the means for mounting, made in the form of a “bracket”.

Comparison of the claimed device with the prior art in scientific, technical and patent documentation for the priority date in the main and related sections shows that the set of essential features of the claimed solution was not known, therefore, it meets the patentability condition of "novelty."

The proposed technical solution is applicable, since it can be manufactured industrially, efficiently, feasibly and reproducibly, therefore, it meets the patentability condition “industrial applicability”.

The inventive utility model is illustrated by drawings, where:

in FIG. 1 - shows an adapter for controlled aerosol spraying, a direct shape;

in FIG. 2 - shows an adapter for controlled aerosol spraying, made with a bend in the middle;

in FIG. 3 - shows spray nozzles for controlled aerosol spraying, mounted on a "bracket";

in FIG. 4 shows a section AA of FIG. 3.

The spray nozzle comprises a spray gun 1 and an adapter 2, which have a cylindrical body. The adapter 2 is made of a direct shape (Fig. 1) and with a bend in the middle (Fig. 2). The inner part of the atomizer 1 is made in the form of a through hole at the outlet of the sprayed medium and is communicated through an adapter with a through hole of the gun barrel. A thread 3 is made on one of the sides of the spray gun 1 at the junction with the adapter 2. In the upper part of the spray gun 1 around the through hole at the outlet of the sprayed medium there is an elevation 4 of a cylindrical shape with a through hole having a slit-like shape (Fig. 4). The adapter 2 has two parts of a larger diameter on the outside and a smaller diameter on the other side at the junction with the atomizer 1 (Fig. 2, 3). A thread 5 is made in the adapter 2 at the junction with the spray gun 1. On both sides of the adapter 2 there are two protruding ribs 6 and 7 located opposite each other. In this case, the atomizer 1 with the adapter 2 is attached to the means for mounting, made in the form of a “bracket” 8 (Fig. 3).

The adapter 2 is made with a bend in the middle, and the threaded part 9 is located at an angle to the landing part of the adapter 2 (Fig. 2). On both sides of the adapter 2 there are two ribs 10 and 11 located opposite each other, with one of the ribs above the place

bending the other below. The atomizer 1 with the adapter 2 are attached to the means for mounting, made in the form of a “bracket” 8 (Fig. 2, 3).

The spray nozzle of the mounting gun for controlled aerosol spraying of the polyurethane medium under pressure has high operational qualities and can be manufactured on standard equipment using modern materials and technologies.

The spray nozzle of the mounting gun for controlled aerosol spraying of the polyurethane medium under pressure works as follows: in the not working position, the spray nozzle is attached with a “bracket” 8 (Fig. 3, 4) to the cylinder adapter (with mounting foam). The cylinder is installed in the mounting gun. Next, a spray gun 1 with a straight line or an adapter having a bend is put on the barrel of the mounting gun.

The proposed utility model is widely used in industry, namely in construction, construction and installation works, insulation of various objects of housing and communal services, both during construction and in domestic conditions.
