Furthermore, the terms "first," "second," and the like in the description of the present utility model, if any, are used for distinguishing between the descriptions and not necessarily for indicating or implying a relative importance.

In the description of the embodiments of the present utility model, it should also be noted that, unless explicitly specified and limited otherwise, the terms "disposed," "connected," and "connected" should be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

As shown in the drawing, the utility model comprises a spray head body 1, a spray cavity 2 penetrating front and back is arranged on the spray head body 1, a horn-shaped nozzle 3 is arranged at the front end of the spray cavity 2, an air inlet pipe joint 4 is arranged at the rear end of the spray cavity 2, and an oil inlet pipe 5 is arranged on the spray cavity 2 close to the horn-shaped nozzle 3.

The air inlet pipe joint 4 is used for connecting a high-pressure air pump, inputting high-pressure air into the spray cavity 2, the oil inlet pipe 5 is used for inputting coating oil into the spray cavity 2, and the coating oil is subjected to liquid film rupture and atomization under the impact of compressed air and is sprayed out of the horn-shaped nozzle 3. The horn-shaped nozzle 3 can scatter atomized coating oil four, increase the spraying area of the atomized coating oil, and effectively reduce oil mist around during spraying from contacting with the outlet end of the nozzle along the wall to form oil drops.

The spray cavity 2, the horn-shaped nozzle 3 and the air inlet pipe joint 4 are integrally milled and formed. The machining precision is high, the spray cavity 2, the horn-shaped nozzle 3 and the air inlet pipe joint 4 are positioned on the same axis, the air flow injection is smooth, and the coating oil is atomized uniformly.

The section of the spray cavity 2 between the trumpet-shaped nozzle 3 and the oil inlet pipe 5 is a conical structure 6 with a large inlet end diameter and a small outlet end diameter, the outlet end diameter of the conical structure 6 is the same as the inlet end diameter of the trumpet-shaped nozzle 3, and the inlet end diameter of the conical structure 6 is the same as the diameter of the spray cavity 2. When the coating oil in the spray cavity 2 is excessive, the coating oil cannot flow outwards due to the conical structure 6, so that oil drops are caused. Meanwhile, when the atomized and sprayed air flow passes through the section 6 of the conical structure, the air flow in the middle part is smoothly sprayed out, and the air flow around the atomized and sprayed air flow is blocked by the side wall of the conical structure 6, so that the atomized and sprayed air flow is compressed towards the middle part, and once entering the horn-shaped nozzle 3, the atomized and sprayed air flow is scattered in four directions, so that oil drops are effectively reduced to form in the horn-shaped nozzle 3.

The ratio of the diameter of the inlet end to the diameter of the outlet end of the conical structure 6 is 1:0.94. The side wall inclination of the conical structure 6 is not large, and the effect of compressing the air flow passing through the conical structure 6 section towards the middle is small while the oil drops are prevented from dripping outwards, so that the influence on the air flow in the spray cavity 2 is small, and the effect of spraying the whole oil mist is not influenced.

The nozzle body 1 at the outlet end of the horn-shaped nozzle 3 is integrally provided with an annular boss 7, a plurality of air nozzles are annularly arranged on the annular boss 7, a plurality of air outlets corresponding to the air nozzles are annularly arranged on the air inlet pipe joint 4, and the air nozzles are communicated with the corresponding air outlets through pipelines.

The distance between the air jet opening and the outlet end of the horn-shaped nozzle 3 is not more than 5mm.

The oil mist sprayed from the horn-shaped nozzle 3 has large middle pressure and relatively small surrounding pressure, so that the adhesion force of the oil mist around the horn-shaped nozzle 3 in the sprayed coverage area is relatively small, in the scheme, part of compressed gas in the spray cavity 2 is sprayed from the air nozzle through the air outlet, so that the annular air flow layer horizontally sprayed at the outlet end of the horn-shaped nozzle 3 can effectively perform secondary spraying on the oil mist with relatively small surrounding pressure sprayed from the horn-shaped nozzle 3, the oil mist pressure is similar to that of the oil mist in the middle, and the coating quality is improved.

The oil inlet pipe 5 is connected to the nozzle body 1 through threads.

The outlet end of the oil inlet pipe 5 is provided with a flow equalizing plate 9, the flow equalizing plate 9 is a mesh plate, and when the coated oil is sprayed into the spray cavity 2 under high pressure, the coated oil is uniformly distributed in the spray cavity 2 through the flow equalizing plate 9, so that the atomization effect is improved.
