Detailed Description

The invention is further described with reference to the drawings, and examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

Fig. 1 shows an embodiment of an adjustable spraying device according to the invention.

The adjustable spraying device comprises a spraying core 1, a spraying body 3, a fixed frame 5 and a spraying seat 7; the spray body 3 is of a cylindrical structure, and a gradually expanding section is arranged on the inner wall of one end of the spray body 3; one end of the spray core 1 is arranged on a fixed frame 5, the fixed frame 5 is fixed at the axial position of the spray body 3, the other end of the spray core 1 is of a gradually expanding structure, and the spray core 1 is arranged in the spray body 3; a gap is arranged between the divergent structure of the spray core 1 and the divergent section of the spray body 3, the distance between the divergent section of the spray core 1 and the fixing frame 5 is adjustable, and the adjustment of the range is realized by adjusting the gap between the spray core 1 and the spray body 3. The divergent section of the nozzle body 3 has the same shape as the divergent structure of the nozzle core 1, and may be conical or parabolic. Spout the seat 7 and be cylindric structure, spout the one end of seat 7 and be connected with spouting the body 3, spout the other end of seat 7 and can be connected with the pipeline.

Specifically, in the present embodiment, the divergent section shape of the spray body 3 and the divergent structure shape of the spray core 1 are conical, and the conical degree can be set according to the spraying area suitable for the spraying device, for example, 120 °.

In this embodiment, realize the distance between core 1 divergent structure and the mount 5 is adjustable, and then the adjustment spouts the structure in clearance between core 1 and the body of spouting for being similar to the lead screw structure, will spout core 1 and mount 5 and pass through threaded connection, mount 5 does not produce relative movement with the circumference of the body of spouting 3, spouts core 1 promptly along the screw rotation of mount 5 the time, and restriction mount 5 does not take place relative rotation for spouting the body 3, guarantees to adjust when the core 1 is spouted in the rotation and spouts the clearance between core 1 divergent structure and the body of spouting 3. Specifically, the fixing frame 5 is configured as shown in fig. 2, and a plurality of blades 10, for example, 3 blades, are disposed on the circumference of the fixing frame, and the plurality of blades are uniformly distributed in the circumferential direction. The inner wall of the spraying body 3 is provided with a groove for accommodating the fixed frame 5, and the groove wall is provided with a limiting device matched with the blade 10 to limit the relative rotation between the fixed frame 5 and the spraying body 3.
