Description

Technical Field

[0001] This utility model belongs to the field of nozzle technology and relates to a nozzle with a cone-shaped spray pattern. Background Technology

[0002] The cone nozzle, through its special internal flow channel and outlet design, sprays fluid in a cone shape, making it widely used in spraying, spraying, fire fighting and other scenarios to achieve uniform coverage and efficient operation.

[0003] Chinese patent publication number CN209174201U discloses a hollow cone-shaped micro-atomizing spray nozzle, including a nozzle body, a first nozzle, a first connecting flange fixedly connected to the bottom of the first nozzle, a first outer shell and a first cavity, the first cavity being fixedly disposed inside the first outer shell, a buffer strip being fixedly connected inside the first cavity, a second nozzle being threadedly connected to the top of the first nozzle, the second nozzle including a second outer shell and a second cavity, the second cavity being fixedly disposed inside the second outer shell, two filter screens being fixedly connected inside the second cavity, one of the filter screens being located on top of the other filter screen, and a third nozzle being threadedly connected to the top of the second nozzle.

[0004] The hollow cone-shaped micro-atomizing spray nozzle provided by this patent mainly achieves the spraying function by sequentially connecting each nozzle component. The lack of a flow guide component and an adjustment device that can change the shape or size of the outlet results in an unsatisfactory cone spraying effect. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the prior art by providing a nozzle with a cone-shaped spray pattern.

[0006] The objective of this utility model can be achieved through the following technical solution: A nozzle with a conical spray pattern includes a nozzle cap, a nut seat, and guide vanes. The nut seat has a cylindrical cavity inside, and the guide vanes are fixedly installed inside the cylindrical cavity. The guide vanes are integrally formed structures and have a cross-wing structure, including a first vane, a second vane, and a connecting platform. The first vane and the second vane have a vertically intersecting structure, and the connecting platform is disposed between the first vane and the second vane. The first vane and the second vane are respectively provided with a first guide groove and a second guide groove. The first guide groove and the second guide groove are arranged longitudinally and are located in the middle of the first vane and the second vane. A conical spray hole is provided at the center of the nozzle cap, and a plurality of guide grooves are provided on the outer surface of the nozzle cap. The ends of the guide grooves are distributed in a circumferential array around the conical spray hole.

[0007] In the above-mentioned nozzle with a conical spray pattern, the nozzle cap is fixedly connected to the front end of the nut seat, the cylindrical cavity is connected to the conical spray hole, and the rear end of the nut seat is provided with external threads.

[0008] In the nozzle with a conical spray pattern described above, a limiting ring is formed inside the cylindrical cavity, and the front ends of the first and second blades are in contact with the end face of the limiting ring.

[0009] In the above-mentioned nozzle with a cone-shaped spray pattern, the nozzle cap has a hemispherical cavity inside.

[0010] In the nozzle with a conical spray pattern described above, an extension is formed at the lower end of the first blade, and the extension extends and protrudes from the centerline of the central region of the guide blade.

[0011] Compared with existing technologies, the nozzle with a conical spray pattern provided by this utility model has the following beneficial effects: 1. Through the guide vanes of the cross-wing structure, the first and second vanes are vertically intersecting and combined with the guide groove to accurately guide the fluid flow direction; 2. Through the hemispherical cavity structure inside the hemispherical body, and through the central conical spray hole of the nozzle cap and the guide groove working together, the fluid is stably formed into a uniform and regular conical spray after multiple guidance and rectification, with excellent consistency in mist coverage and distribution; 3. The overall structure is simple, and the guide vanes are integrally formed cross wings, reducing the number of parts and processing steps, effectively reducing manufacturing costs and subsequent maintenance costs while ensuring spray performance.

[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figures 1 to 4 As shown, this embodiment includes a nozzle cap 1, a nut seat 2, and a guide vane 3. The nut seat 2 has a cylindrical cavity 21 inside, which provides space for fluid flow and component installation. The rear end of the nut seat 2 has an external thread 22, which facilitates quick connection and fixation with external pipelines or equipment. A limit ring 23 is formed inside the cylindrical cavity 21, which is used to axially position the guide vane 3.

[0016] like Figure 1 and Figure 2 As shown, the guide vane 3 is an integrally formed structure with a cross-wing design. The guide vane 3 includes a first vane 31, a second vane 32, and a connecting platform 33. The first vane 31 and the second vane 32 are vertically intersecting. The connecting platform 33 is located at the intersection of the two vanes to enhance the overall structural strength. The front ends of the first vane 31 and the second vane 32 are in contact with the end face of the limiting ring 23 to ensure the installation stability of the guide vane 3 in the cylindrical cavity 21. The first vane 31 and the second vane 32 are respectively provided with a first guide groove 34 and a second guide groove 35. The first guide groove 34 and the second guide groove 35 are both arranged longitudinally and located in the middle of the corresponding vane, which can guide the fluid to flow along a preset path and improve the uniformity of fluid distribution.

[0017] To elaborate further, such as Figure 1 and Figure 2 As shown, the lower end of the first blade 31 has an extension 311, which extends and protrudes from the centerline of the central region of the guide vane 3, further optimizing the fluid guiding effect.

[0018] To elaborate further, such as Figure 1 and Figure 2 As shown, the first blade 31 and the second blade 32 are arranged in a 45° structure that is perpendicular to each other. The end faces of the first blade 31 and the second blade 32 are obliquely arranged with respect to the cylindrical cavity 21, which further enhances the flow guiding effect.

[0019] like Figure 1 and Figure 4 As shown, the nozzle cap 1 is fixedly connected to the front end of the nut seat 2. Its interior is a hemispherical cavity 13, which can buffer and pre-diffuse the incoming fluid. A conical nozzle hole 11 is provided at the center of the nozzle cap 1. The conical nozzle hole 11 is connected to the cylindrical cavity 21 of the nut seat 2 to form the main channel for fluid ejection. Several guide grooves 12 are provided on the outer surface of the nozzle cap 1. The ends of each guide groove 12 are arranged in a circumferential array around the conical nozzle hole 11, which, together with the internal flow channel, forms a regular conical spray pattern.

[0020] During operation, the fluid enters the cylindrical cavity 21 from the rear end of the nut seat 2. After being guided by the first guide groove 34, the second guide groove 35 and the extension 311 of the guide vane 3, the fluid enters the hemispherical cavity 13 of the nozzle cap 1 for buffering and diffusion. Finally, it is sprayed out through the conical nozzle 11 and the circumferential array of guide grooves 12 to form a stable and uniform conical spray.

[0021] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0022] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
