Detailed implementation manners

[0018] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0019] As Figures 1 to 3 shown, this improved drip irrigation nozzle includes a nozzle body 100 and a nozzle installation part 200. The nozzle body 100 is in a cap-like or cover-like structure, which can be arc-shaped or cylindrical. The top of the nozzle installation part 200 is a connecting part 210, which is screwed to the nozzle body 100. A number of circumferentially arranged insertion pieces 220 are formed below the nozzle installation part 200, presenting an inverted long conical shape as a whole, which is convenient for inserting the drip irrigation nozzle into the soil for installation.

[0020] As Figures 2 to 3 shown, the installation part at the top of the nozzle installation part 200 is in a ring-like structure. A connecting external thread 212 is spirally provided on the outer side wall of the ring. A connecting bottom support 211 is formed at the bottom of the connecting part 210. The outer diameter of the connecting bottom support 211 is larger than the outer diameter of the ring-like connecting part 210, and its extended part abuts against the bottom end face of the nozzle body 100, playing a limiting role.

[0021] A number of circumferentially equidistantly arranged insertion pieces 220 are integrally formed below the connecting bottom support 211. The number of insertion pieces 220 should be no less than three, preferably four. The width of the insertion piece 220, that is, the distance from the outer edge of the insertion piece 220 to the central connection of each insertion piece 220, gradually decreases from top to bottom, forming an inverted long conical shape as a whole. During installation, only the lower part of the nozzle installation part 200 needs to be inserted into the soil, and the installation is convenient and stable. A structural block 222 for connecting the two is formed between adjacent insertion pieces 220, and the structural block 222 is used to strengthen the structural strength at the nozzle installation part 200.

[0022] Among several insertion pieces 220, an arc-shaped interface groove 221 is formed in one of the insertion pieces 220. A water pipe interface 230 is formed in the interface groove 221. The orientation of the water pipe interface 230 is the same as the outward direction of the insertion piece 220. A ring of interface retaining rings 231 is formed on the outer side wall at the water inlet of the water pipe interface 230. The interface retaining rings 231 slightly expand from the outside to the inside, which is convenient for relatively fastening and fixing the water pipe through the interface retaining rings 231 when connecting the water pipe to the water pipe interface 230, preventing loosening and water leakage.

[0023] The center of the connecting base 211 bulges upward in the connecting part 210 to form an installation part water outlet 214. The caliber size at the installation part water outlet 214 gradually expands from bottom to top. An L-shaped water supply pipeline 232 is provided inside the nozzle installation part 200 between the water pipe interface 230 and the installation part water outlet 214. During operation, water flows in from the water pipe interface 230, flows through the water supply pipeline 232, and enters the inside of the nozzle body 100 from the installation part water outlet 214. By arranging the water pipe interface 230 on the side of the nozzle installation part 200, drip irrigation nozzles can be connected in series with each other in the soil, realizing the continuous setting of large-area drip irrigation and breaking through the limitation of only being applicable in a small area.

[0024] As Figure 3 shown, an internal connecting thread 130 is formed on the inner side wall at the bottom of the nozzle body 100. The internal connecting thread 130 corresponds and cooperates with the external connecting thread 212 of the connecting part 210, so that the nozzle body 100 is screwed to the nozzle installation part 200. The nozzle body 100 forms an uneven hand-held part 140 on the outer side wall at the bottom, increasing the friction on the outer side wall of the nozzle body 100, so that the user can screw the nozzle body 100 onto the connecting part 210 through the hand-held part 140.

[0025] A limiting and guiding structure 120 is formed downward at the center inside the nozzle body 100. The limiting and guiding structure 120 is formed by combining two coaxial rings. After the nozzle body 100 and the nozzle installation part 200 are assembled, the small ring on the inner side in the limiting and guiding structure 120 extends into the installation part water outlet 214. The outer side wall of the small ring is not in contact with the inner side wall of the installation part water outlet 214. The large ring on the outer side is sleeved on the outside of the installation part water outlet 214. The inner side wall of the large ring is also not in contact with the outer side wall of the installation part water outlet 214. Through the cooperation of the limiting and guiding structure 120 and the installation part water outlet 214, a long and narrow water flow path that spreads from the installation part water outlet 214 to the surroundings is formed, which plays a role in increasing the water flow velocity and pressure.

[0026] The nozzle body 100 is provided with a plurality of drip irrigation water outlet holes 110 on the side wall above the connecting internal thread 130. The water outlet holes of conventional drip irrigation nozzles are usually arranged in a single row at equal circumferential distances. If there are more water outlet holes, the distance between the holes will be smaller, and it is easy to age and damage due to the long-term erosion of water flow after long-term use. If there are fewer water outlet holes, the water output and water outlet efficiency of drip irrigation will be affected. The utility model has improved the above problems. Two rows of drip irrigation water outlet holes 110 are provided on the nozzle body 100. The drip irrigation water outlet holes 110 on each row are arranged at equal circumferential distances, and the drip irrigation water outlet holes 110 on different rows are arranged in a staggered manner. This not only increases the overall number of drip irrigation water outlet holes 110, improves the water output and water outlet efficiency of the drip irrigation nozzle, but also increases the distance between the holes, making the service life of the nozzle body 100 longer and more practical.

[0027] Further explanation, to strengthen the fastening of the screw connection between the nozzle body 100 and the nozzle installation part 200 and prevent loosening and leakage between the two due to water flow impact, a plurality of limiting teeth 213 are evenly formed in the circumferential direction on the inner side wall of the connecting part 210. Two limiting pieces 121 are symmetrically arranged on both sides of the limiting drainage structure 120. As the nozzle body 100 is gradually screwed into and installed on the connecting part 210, the limiting pieces 121 gradually approach the limiting teeth 213 until they extend into the space between the limiting teeth 213 and are limited and fixed by them.

[0028] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0029] Although various terms are used more in this article, the possibility of using other terms is not excluded. Using these terms is only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional limitation is contrary to the spirit of the present invention.
