Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, and in particular to an irrigation atomizing nozzle structure. Background Technology

[0002] The cross-shaped atomizing nozzle adopts a compact, single-section structure, with an atomizing core featuring a guide groove. Under high pressure, the liquid flows through the guide groove, forming a high-speed swirling stream. After being constrained by the front nozzle orifice, it is broken into fine droplets by centrifugal force, creating a hollow cone-shaped mist field. This structure combines excellent anti-clogging properties with uniform atomization, making it widely applicable in fields such as agricultural irrigation.

[0003] As per the instruction manual Figure 4 As shown, a common atomizer coil is a small, disc-shaped metal or injection-molded part with a precisely machined channel in the center. To improve the coil's strength, it is currently typically manufactured using a one-piece molding process. However, according to the instruction manual... Figure 5 As shown, this type of atomizing core requires the coordinated manufacturing of an upper mold, a lower mold, and a side mold, resulting in a complex manufacturing process and high production costs. Utility Model Content

[0004] Therefore, it is necessary to provide an irrigation atomizing nozzle structure to address the problem that the current atomizing core requires multi-directional molding due to its special structure, which leads to complex manufacturing processes and high production costs.

[0005] An irrigation atomizing nozzle structure includes: The core column has a flow guide groove at its bottom, and the side end of the flow guide groove expands in the direction away from the axis of the core column and penetrates the arc surface of the core column. A positioning ring is fixedly connected to the arc surface of the core column, and the inner top wall of the guide groove is located above the positioning ring. The core column and the positioning ring are manufactured by an integral molding process.

[0006] In one embodiment, the horizontal cross-sectional shape of the guide channel is fan-shaped, and the included angle of the fan shape is ninety degrees.

[0007] In one embodiment, the number of the flow channels is four, and the four flow channels are evenly distributed in a ring around the axis of the core column.

[0008] In one embodiment, the bottom corners of the core column are rounded, and the inner corners of the guide groove are also rounded.

[0009] In one embodiment, the ratio of the height of the guide groove to the height of the core column is five to four.

[0010] In one embodiment, the top of the positioning ring is fixedly connected to an ear plate, the end of the ear plate facing the core post is fixedly connected to the core post, and the core post, positioning ring and ear plate are manufactured by integral molding.

[0011] In one embodiment, the width of the ear plate is less than the shortest straight distance between two adjacent guide grooves, and the ear plates and guide grooves are staggered in the circumferential direction of the core column.

[0012] In one embodiment, there are two ear plates, which are symmetrically distributed on both sides of the core axis.

[0013] Beneficial effects 1. In the above-mentioned irrigation atomizing nozzle structure, the guide groove at the bottom of the core column expands outward from the axis of the core column and extends through the arc surface of the core column. It is fixedly connected to the arc surface of the core column with a positioning ring, and the top wall of the guide groove is set above the positioning ring. When the core column and the positioning ring are manufactured by an integral molding process, the mold only needs to be upper and lower molds to complete the forming of the guide groove, eliminating the use of side molds, significantly reducing manufacturing complexity and production costs, while maintaining the structural integrity and strength of the atomizing core.

[0014] 2. The clamping cap engages with the U-shaped clip on the cross-shaped main tube via an L-shaped locking block, and is installed in the annular groove with an O-ring seal, enabling quick clamping and disassembly without tools; the ear plate contacts the atomizing cap to ensure stable positioning of the atomizing core, thereby simplifying installation and maintenance steps, improving ease of use and sealing reliability, while maintaining a uniform atomization effect.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figure 1 - Figure 5 This invention describes the structure of an irrigation atomizing nozzle.

[0020] In one embodiment, an irrigation atomizing nozzle structure includes: like Figure 3 As shown, the cross-shaped main body tube is the basic component of the nozzle, used to connect to the water supply line. The liquid inlet end of the cross-shaped main body tube needs to be connected to the water supply line via heat fusion, a connection method that is robust, reliable, and provides good sealing. Inside the cross-shaped main body tube is a precision-machined cavity used to accommodate and position the atomizing core. Swirl grooves are formed inside the cavity to help the liquid form a swirling flow, improving the atomization effect. U-shaped clips are fixedly connected to the surfaces of the four liquid outlet pipes of the cross-shaped main body tube. Annular grooves are formed on the surfaces of the four liquid outlet pipes of the cross-shaped main body tube, located on the side of the U-shaped clip facing away from the liquid inlet end of the cross-shaped main body tube. O-rings are installed inside the annular grooves. This structure provides a basis for the quick snap-fit ​​installation and sealing of the compression cap.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the atomizing core includes a core post 100 and a positioning ring 200; The bottom of the core column 100 is provided with a guide groove 110. The side end of the guide groove 110 expands in the direction away from the axis of the core column 100 and penetrates the arc surface of the core column 100. The positioning ring 200 is fixedly connected to the arc surface of the core column 100, and the inner top wall of the guide groove 110 is located above the positioning ring 200. The core column 100 and the positioning ring 200 are manufactured by an integral molding process. The integral molding process ensures the structural strength and integrity of the components and effectively reduces potential failure points caused by assembly.

[0022] The horizontal cross-sectional shape of the guide channel 110 is fan-shaped with an included angle of 90 degrees. This shape is beneficial for guiding the liquid to generate a stable and uniform high-speed swirling flow. There are four guide channels 110, which are evenly distributed in a ring around the axis of the core column 100, making the liquid flow more symmetrical and stable and ensuring atomization uniformity. The bottom corners of the core column 100 and the inner corners of the guide channel 110 are also rounded. The rounded corner design can effectively reduce fluid resistance and pressure loss, avoid stress concentration, and improve structural durability. The height ratio of the guide channel 110 to the height of the core column 100 is 5:4. This ratio has been optimized to maximize the flow area and guide length of the guide channel 110 within a limited space.

[0023] The top of the positioning ring 200 is fixedly connected to an ear plate 300. The end of the ear plate 300 facing the core column 100 is fixedly connected to the core column 100. The core column 100, the positioning ring 200 and the ear plate 300 are manufactured by integral molding, which enhances the connection strength. The width of the ear plate 300 is less than the shortest straight distance between two adjacent guide grooves 110. The ear plate 300 and the guide groove 110 are staggered around the core column 100 to avoid interference with the fluid channel. There are two ear plates 300. The two ear plates 300 are symmetrically distributed on both sides of the axis of the core column 100, providing balanced support force to ensure that the atomizing core is accurately and stably positioned in the cavity.

[0024] like Figure 3 As shown, the clamping cap is manufactured using a one-piece molding process, consisting of an atomizing cap, two L-shaped locking blocks, and two levers, resulting in a robust structure. The atomizing cap is inserted into the surface of the liquid outlet pipe of the cross-shaped main tube, with the ear plate 300 and the O-ring in contact with the atomizing cap. The two L-shaped locking blocks and two levers are staggered around the circumference of the atomizing cap, and the L-shaped locking blocks engage with the U-shaped locking components, enabling quick and tool-free locking and disassembly, simplifying installation and maintenance procedures.

[0025] In this embodiment, the installation and usage instructions for the atomizing nozzle are as follows: For initial installation, first embed the O-ring into the annular groove of the liquid outlet pipe of the cross-shaped main tube; then insert the core post 100 of the atomizing core (with the guide groove 110 facing inward) axially into the cavity of the cross-shaped main tube until the positioning ring 200 contacts the tube end face. Remove the pressure cap and press the atomizing cap onto the outside of the liquid outlet pipe of the cross-shaped main tube, aligning the L-shaped locking block with the U-shaped locking piece on the cross-shaped main tube. Push the lever axially; the lever, through the atomizing cap, drives the L-shaped locking block to engage with the inside of the U-shaped locking piece until the protruding end face of the L-shaped locking block abuts against the U-shaped locking piece, indicating a secure engagement. Finally, heat-fuse the liquid inlet end of the cross-shaped main tube to the water supply pipe for water testing.

[0026] Atomizer coil replacement and maintenance instructions: First, ensure the water supply is completely disconnected. When replacing, use your fingers to pinch the two levers on the clamping cap towards the center, causing the levers to rotate the L-shaped locking block and disengage from the U-shaped locking piece via the atomizer cap. Then, pull out the clamping cap axially. Directly remove the old atomizer coil for cleaning or replacement. Place the new or cleaned atomizer coil back into the cross-shaped main tube cavity in the correct orientation, then reinstall the clamping cap following the installation procedure described above. Finally, test with water.

[0027] Normal operation instructions: When the cross-shaped atomizing nozzle is working normally, water enters from the inlet end of the cross-shaped main tube and flows through the swirling grooves in the internal cavity to generate an initial swirling flow. Subsequently, the water is guided into the four fan-shaped guide grooves 110 of the atomizing core. Since the side ends of the guide grooves 110 expand away from the axis of the core column 100 and are evenly distributed in a 90-degree fan shape, the liquid is guided to form a stable, high-speed swirling flow. When this high-speed rotating liquid is finally sprayed out from the atomizing cap with the pressure cap, it is pulverized by centrifugal force, achieving uniform atomization. The positioning ring 200 and the ear plate 300 ensure the stable positioning of the atomizing core in the cavity, which is the key to forming a stable swirling flow.

[0028] As per the instruction manual Figure 2 As shown, since the guide channel 110 is a straight channel parallel to the core post 100, the lower mold of this mold only needs to be designed to fill the protrusion of the guide channel 110 to meet the manufacturing requirements of the guide channel 110. The remaining part of the lower mold and the upper mold only need to have manufacturing cavities opened according to the shape of the core post 100, the positioning ring 200 and the two ear plates 300 combined. During the use of this matching mold, the upper mold only needs to be raised and lowered in the vertical direction to complete the mold closing or demolding. Compared with the instruction manual attached Figure 5 The existing atomizer core manufacturing mold shown not only eliminates the need for a side mold while retaining the original functions of the atomizer core, effectively reducing the complexity and cost of manufacturing the atomizer core, but also effectively reduces burrs after manufacturing the atomizer core and reduces subsequent maintenance costs, further lowering the manufacturing cost of the atomizer core.

[0029] It should be noted that the instruction manual includes... Figure 2 Included with instruction manual Figure 5 The image only shows a portion of the mold with the manufacturing cavity during the manufacturing process of the atomizer core. The specific mold model and function, as well as the processing technology and equipment, need to be selected or customized according to the actual situation, and will not be elaborated here.
