Abstract

The utility model relates to an improvement on a spray head injection nozzle. The utility model is characterized in that supercharging holes (5) which are smaller than the internal diameter of inlet holes (2) step by step are arranged at the right end of inlet holes (2), an injection nozzle groove (4) interpenetrating with supercharging holes (5) is arranged at the right side face of an injection head body (3) in order to compel liquid to eject in a fan-shaped spray state under the function of the injection nozzle groove (4) after liquid goes into supercharging holes (5) to realize small raindrop impact strength, even spray, and prominent enhancement of work efficiency. Meanwhile, because inlet holes (2) and supercharging holes (5) are made into integration, the utility model has the advantages of simple structure of the injection head, easy production and reduction of production costs.

Description

Fan spray head

The utility model relates to a kind of improvement of the apparatus shower nozzle nozzle of spraying.

At present, no matter spray insecticide, the drought resisting of still spraying, liquid is by behind the inlet opening, the nozzle of joining through other directly sprays liquid again, and its advantage is that range is far away, but the liquid of ejection is cylindric ejection, rainfall splash intensity is big, sprays inhomogeneously, causes partially liq to fail to make full use of.

The purpose of this utility model is to provide a kind of liquid of nozzle ejection that can make to be fan-shaped ejection, and rainfall splash intensity is little, and fogging degree is good, sprays uniform shower nozzle nozzle.

The technical scheme that the utility model solves is: be shaped on the pipe tooth on the left end excircle of sprayer body, in the centerbody of sprayer body, be shaped on the inlet opening, be characterized in: the right-hand member in the inlet opening is shaped on progressively the pressurized hole less than the inlet opening internal diameter, and is shaped on the nozzle groove that connects with pressurized hole on the right flank of sprayer body.

The utility model advantage is: 1) because one is made in inlet opening and pressurized hole, make simple in structure, easy to manufacture, cost is low; 2) owing on the right flank of sprayer body, be shaped on the nozzle groove that connects with pressurized hole, after making that liquid enters pressurized hole, produce strong extruding, force liquid to erupt from different perspectives, under the effect of nozzle groove, make liquid become fan-shaped spray pattern ejection, so rainfall splash intensity is little, spray evenly, significantly improve work efficiency.

Describe a most preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is a longitudinal sectional drawing of the present utility model;

Fig. 2 is that the B of Fig. 1 is to view;

Fig. 3 is the A-A profile of Fig. 2.

As Fig. 1, Fig. 2, shown in Figure 3, sprayer body 3 (also can use metal material) made of plastic, on the left end excircle of sprayer body 3, be shaped on pipe tooth 1, be convenient to assembling with water inlet pipe, in the centerbody of sprayer body 3, be shaped on inlet opening 2, the internal diameter that 2 right-hand member is shaped on progressively less than inlet opening 2 in the inlet opening is cone shape pressurized hole 5, the supercharging angle α of pressurized hole 5 can be 20 °～120 °, present embodiment supercharging angle α is 60 °, on the right flank of sprayer body 3, be shaped on the nozzle groove 4 that connects with pressurized hole 5, pressurized hole 5 can also be made polygonal pyramid shape, all within open scope of the present utility model, nozzle groove 4 can be vertical with the center line of inlet opening 2, also can be circular arc, also all disclose within the scope of the present utility model, present embodiment adopts and is circular arc, and the minimum point of circular arc is positioned on the center line of pressurized hole 5, and two peaks of circular arc are positioned on the excircle of sprayer body 3 right flanks; The cross section of nozzle groove 4 can be rectangle, triangle or other polygon, all within the utility model scope of disclosure, the cross section of the nozzle groove 4 of present embodiment adopts triangle, and formed eruption angle β is 30 °, and eruption angle β all can implement in 20 °～120 ° scopes.In addition, the right-hand member excircle diameter of sprayer body 3 can make the plant liquid that ejects strengthen greater than the body body diameter of sprayer body 3 like this.

Claims

1, a kind of Fan spray head, on the left end excircle of sprayer body (3), be shaped on pipe tooth (1), be shaped on inlet opening (2) therein in the heart body, it is characterized in that: the right-hand member of (2) is shaped on progressively the pressurized hole (5) less than inlet opening (2) internal diameter in the inlet opening, and is shaped on the nozzle groove (4) that connects with pressurized hole (5) on the right flank of sprayer body (3).

2, a kind of Fan spray head according to claim 1 is characterized in that: nozzle groove (4) is circular arc, and the minimum point of circular arc is positioned on the center line of pressurized hole (5), and two peaks of circular arc are positioned on the excircle of sprayer body (3) right flank.

3, a kind of Fan spray head according to claim 1 and 2 is characterized in that: the cross section of the nozzle groove (4) of circular arc formation eruption triangular in shape angle β, angle β is generally in 20 °～120 ° scopes in eruption.
