By more than, liquid after the compression is by flowing in gun shot 70 pipes in the tank 711 of connecting support 71, spray through the helical guide groove 811 of diversion seat 81 hole 831 again by capping 83, and but mat control lever 80 moves and adjusts the distance of taper 812 with the capping 83 hole 83I of diversion seat 81 front ends, to change what of liquid ejection; Yet this kind spray gun structure but is easy to generate following problem when using:

One, spraying range is little, operating efficiency is poor

Because this spray gun structure system directly sprays the liquid of compression through the hole of nozzle mechanism capping, there is no mixing air, so cause atomization of liquid poor effect, make spraying range narrower and small relatively, have a strong impact on the operating efficiency of spraying agent, cause the waste of time, manpower.

Be subject to windage when two, spraying

Because the Spray gun nozzle structure of commonly using, outside its hole that liquid is sprayed directly is exposed to, and outdoor wind-force is stronger, if attacked by wind, medicament is dispersed everywhere, so has a strong impact on the usefulness of medicament, and causes and spray uneven phenomenon.

Main purpose of the present utility model is to provide a kind of atomizing effect that spray liquid is gone out better Spray gun nozzle with the augmentation spraying range.

Another purpose of the present utility model is to provide a kind of Spray gun nozzle with the effect of becalming.

The purpose of this utility model is to realize like this, a kind of Spray gun nozzle, it comprises connecting support, seal ring and the capping that is fixedly linked in the barral of a gun front end, it is characterized in that: this nozzle also is provided with an outer cover in the capping outside, form the cover body of a sealing around this outer cover outer end, its central authorities then set firmly a volution to be locked in the external screw thread of connecting support, seal ring and capping are folded between volution and the connecting support end face, should outer cover in not only the open-work that annular section of the peripheral cover body of volution inboard is provided with some circular rows but also runs through.

The utility model adopts above-mentioned design, establish an outer cover and be screwed together in the connecting support front end in the capping front end, to compress a capping and a seal ring, the inboard of this outer cover is provided with some annular open-works, like this, liquid produces a sucking action during by the ejection of the hole of capping, air is sucked in the cover body of outer cover by open-work, spray, make atomizing effect better and make the liquid mixing air be vaporific, and effective augmentation spraying range, and tool saves time, labour-saving usefulness.The outer cover periphery cover body that is provided with sealing is surrounded on the hole periphery of capping again, can effectively block high wind like this and fly away to avoid liquid by the hole ejection to be blown everywhere, and influence medicament usefulness.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a three-dimensional exploded view of the present utility model.
