detailed description:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

As shown in Figures 1 to 3, the utility model describes a new type of spray nozzle, which includes a nozzle core 1 and a nozzle cover 2, wherein one end of the nozzle cover 2 is an open portion 21 , used to connect with the port of the liquid supply pipeline, the other end of the nozzle cover 2 is a bottom cover 22 with a central hole 220; the nozzle core 1 is arranged inside the nozzle cover 2 and contacts the bottom cover 22 of the nozzle cover 2, The nozzle core 1 has a main body 11 having an inner diameter equivalent to that of the nozzle cover 2, and the side wall of the main body 11 is evenly provided with three first grooves 111 parallel to the axial direction and penetrating both ends of the main body 11. 11 The bottom surface in contact with the nozzle cover 2 is provided with a central concave surface 112 opposite to the central hole 220 of the bottom cover 22 of the nozzle cover 2, and a central concave surface 112 is provided on the bottom surface along the tangential direction of the central concave surface 112 to communicate with the central concave surface 112 and the second There are three second grooves 113 in one groove 111; in this embodiment, the number of the first grooves 111 and the second grooves 113 are three respectively, that is, they are evenly distributed at 120°.

The utility model adopts the above-mentioned structure. When assembling, the nozzle core 1 is put into the nozzle cover 2 from the opening part 21 first, and the side of the nozzle core 1 with the central concave surface 112 is in contact with the bottom cover 22 of the nozzle cover 2, and then the nozzle The cover 2 is connected to the port of the liquid supply pipe so that the nozzle core 1 is confined between the end surface of the liquid supply pipe and the nozzle cover 2 , and the liquid supply pipe communicates with the first groove 111 on the side wall of the nozzle core 1 . At this time, when there is pressurized liquid supply in the liquid supply pipeline, the liquid will be divided into several strands and pass through the first groove 111 and the second groove 113 respectively, and then flow into the central concave surface 112 along the tangential direction of the central concave surface 112, thereby A swirl is formed in the concave surface 112, and then sprayed out through the central hole 220 of the bottom cover 22 to form a swirl-like spray, so that the spray is evenly sprayed on the surface of the object to be sprayed.

The nozzle core 1 also includes an extension section 12 that is coaxial with the main body 11 and has a diameter smaller than that of the main body 11. Several positioning ribs 13 are also formed on the periphery of the extension section 12. The radius of the side wall of the positioning rib 13 is also smaller than that of the main body. 11 radius, through the positioning rib 13 and the extension 12, it is more convenient to connect the nozzle core 1 to the liquid supply pipe or connecting pipe to be connected, and the positioning rib 13 is positioned against the inner wall of the liquid supply pipe or connecting pipe.

The outer end surface of the bottom cover 22 of the nozzle cover 2 is also provided with a small concave plane 221 concentric with the central hole 220 to make the spray diverge better.

As shown in FIGS. 4 and 5 , the spray nozzle also includes a connecting pipe 3 connected to the opening 21 of the nozzle cover 2 and used for positioning the nozzle core 1 . That is, through the direct assembly of the nozzle cover 2, the nozzle core 1 and the connecting pipe 3 in this embodiment, the connecting pipe 3 is used to connect with the external liquid supply pipe. The connecting pipe 3 can be a straight pipe or a bendable pipe , so that the spray direction can be adjusted at any time, and it is more convenient to use.

The inner wall of the opening 21 of the nozzle cover 2 is provided with a concave buckle 211, which is convenient to engage with the convex buckle on the outer wall of the liquid supply pipe or the connecting pipe to ensure a stable connection.

The spray nozzle of the utility model is simple in structure, convenient to assemble and use, and can be used in conjunction with the liquid spray pipes of various manual, mechanical, electronic, etc. liquid spray devices. It can be disassembled, cleaned and reused.
