Description

Technical Field

[0001] This utility model relates to fountain equipment, and more particularly to a ring-hole cluster fountain nozzle. Background Technology

[0002] Musical fountains, with their dynamic water jets, dazzling lights, and beautiful music, add immeasurable charm to the urban landscape. The core equipment of a musical fountain—the nozzles—is key to achieving these dynamic effects.

[0003] Musical fountains can be categorized by their location into dry-land fountains and pool fountains. They can also be classified by their spray pattern, such as direct-jet nozzles, rotating nozzles, and fan-shaped nozzles. Direct-jet nozzles, which project a stable and powerful water jet, are suitable for large-scale musical fountain performances, creating spectacular visual effects. Regardless of whether it's a dry-land fountain or a pool fountain, a direct-jet nozzle is a constricted tubular nozzle structure. Water is pressurized and then sprayed out in a jet shape from the nozzle opening. If the water jet is thick, the nozzle outlet will be large. While pool fountains are mostly located in pools and don't affect pedestrians, dry-land fountains are on the ground. Their nozzle outlets are larger, making it easy for delicate high heels to get stuck. Furthermore, the constricted structure at the top of the nozzle creates gaps between the nozzle and the light panel, which can also trap foreign objects and obstruct pedestrian movement.

[0004] Furthermore, because the water flow pumped up by the water pump is relatively turbulent, a flow regulator valve needs to be installed at the bottom of the nozzle to better form a horizontal, transparent water jet. The investment in the flow regulator valve also increases the overall cost of the fountain. Moreover, the thicker the water jet, the greater the water demand, which places higher demands on the water pump and also increases the electricity consumption.

[0005] With the maturity of 3D printing technology, fountain nozzles that could only be formed by casting in the past can now have their internal flow channels manufactured by 3D printing, providing a new direction for the fountain industry and designing a fountain nozzle that can replace the existing direct-shot nozzles. Utility Model Content

[0006] The purpose of this invention is to provide a ring-hole cluster fountain nozzle that solves the above-mentioned problems.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a ring-hole cluster fountain nozzle, comprising a nozzle, the nozzle being a solid cylindrical structure, the nozzle being 3D printed, a flow channel vertically printed inside the nozzle, the flow channel being composed of an upper ring-hole flow channel and a lower water inlet flow channel, the ring-hole flow channel being composed of several vertically opened water spray holes arranged in a ring, the water inlet flow channel being a frustum-shaped cone with a smaller top and a larger bottom, an inner cone 3D printed inside the water inlet flow channel with a larger top and a smaller bottom, the water spray holes on the ring-hole flow channel being connected to the annular top of the water inlet flow channel, and a diverter plate 3D printed at the lower water inlet of the water inlet flow channel.

[0008] Preferably, there are 2-10 diverter plates, which are centrally symmetrically distributed with the inner cone as the center.

[0009] Preferably, the lower end of the flow divider is flush with the bottom of the nozzle, and a gap is left between the upper end of the flow divider and the annular flow channel to form a horizontal flow cavity.

[0010] Preferably, the annular flow channel has 12-18 spray holes with a diameter of 0.4-0.6 cm, and the distance between adjacent spray holes is no greater than 0.4 cm.

[0011] Preferably, the upper ends of the water spray holes are all inclined towards the center of the nozzle, with an inclination of 0.5-1.5°.

[0012] Preferably, the height ratio of the annular flow channel to the water inlet flow channel is 1:1.

[0013] Preferably, the area ratio of the top outlet of the annular flow channel to the bottom inlet of the inlet flow channel is 1:6.

[0014] Preferably, the taper of the inner cone is 38°.

[0015] Preferably, the nozzle, inner cone, and flow divider are integrally formed.

[0016] Preferably, the nozzle is made of stainless steel and 3D printed as a whole.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] (1) This utility model utilizes current 3D printing technology and combines it with the structural design of the flow channel to design a ring hole cluster fountain nozzle, which can completely replace the existing direct nozzle. By using 3D printing technology to print the internal flow channel, the nozzle of this utility model does not need to be designed as a constricted tube structure, but is a column structure. Its diameter matches the diameter of the nozzle mounting hole in the center of the dry ground fountain light panel. This ensures that there are no gaps around the nozzle, which would hinder pedestrians from walking. Moreover, the upper surface of the nozzle is flat, so there is no need to worry about tripping.

[0019] (2) In order to achieve direct water jet, the annular flow channel was designed. The annular flow channel adopts the water outlet design of the annular spray hole, which replaces the original design of one water outlet of the water jet. No matter how large the diameter of the water jet is, it is only necessary to increase the number of spray holes. There is no need to enlarge the nozzle outlet. This not only solves the problem that the outlet of the existing direct spray nozzle is too large, and the heel of high heels is easy to get stuck, which hinders pedestrians from walking, but also arranges the spray holes according to the water jet diameter requirements. This not only presents the effect of a thicker water jet, but also greatly reduces the water demand and saves energy.

[0020] (3) In order to make the water jet from each water jet hole of this utility model a horizontal transparent water jet, the water inlet channel is designed in the nozzle. Through the conical water inlet channel and the inverted conical inner cone design, the water flow can be uniformly converged into the annular channel, ensuring that the water inlet volume of each water jet hole is consistent. Moreover, during the convergence and guiding process, the water flow gradually changes from turbulent flow to horizontal flow. At the same time, the annular constriction structure can accelerate the water flow and make the water jet height higher.

[0021] (4) A flow divider plate is also directly printed in the flow channel. The flow divider plate plays the role of diverting and guiding the flow, dividing the water flow into multiple channels, reducing the mutual influence between the water flows, and facilitating the transformation of the water flow from turbulent flow to horizontal flow. Through the design of the water inlet flow channel and the flow divider plate, the nozzle of this utility model does not need to be equipped with a flow stabilizing valve, reducing the cost of accessories and making installation more convenient.

[0028] The present invention will be further described below.

[0029] Example: This invention utilizes current 3D printing technology, combined with a flow channel structure design, to create a ring-hole cluster fountain nozzle that can completely replace existing direct-shot nozzles. See [link / reference]. Figures 1 to 5 The nozzle 1 is a solid cylindrical structure, which is 3D printed. The nozzle 1 has vertically printed flow channels inside. By using 3D printing technology to print the internal flow channels, the nozzle 1 of this utility model does not need to be designed as a constricted tubular structure, but is a cylindrical structure. Its diameter matches the diameter of the nozzle 1 mounting hole in the center of the dry fountain light panel. This ensures that there are no gaps around the nozzle 1, which would obstruct pedestrians. Moreover, the upper surface of the nozzle 1 is flat, so there is no need to worry about tripping.

[0030] To achieve a direct water jet, a flow channel was designed, consisting of an upper annular flow channel 2 and a lower inlet flow channel 3. The annular flow channel 2 comprises several vertically arranged spray holes 21, which are arranged in a ring. This ring-shaped spray hole design replaces the original single-outlet design. Regardless of the water jet diameter, only the number of spray holes 21 needs to be increased, without needing to enlarge the nozzle 1's outlet. This not only solves the problem of the existing direct-jet nozzle 1 having a large outlet, which can easily cause high heels to get stuck and obstruct pedestrians, but also, by arranging the spray holes 21 according to the water jet diameter requirements, it not only produces a thicker water jet effect but also significantly reduces water consumption and saves energy.

[0031] To ensure that the water jet from each nozzle 21 is a horizontal, transparent jet, an inlet channel 3 is designed inside the nozzle 1. The inlet channel 3 is a frustum-shaped cone, wider at the bottom than the top. An inner cone, wider at the top and narrower at the bottom, is 3D-printed inside the inlet channel 3. All nozzles 21 on the annular channel 2 are connected to the annular top of the inlet channel 3. Through the conical inlet channel 3 and the inverted conical inner cone design, the water flow is evenly distributed into the annular channel 2, ensuring a consistent water intake for each nozzle 21. Moreover, during the confluence and diversion process, the water flow gradually changes from turbulent to horizontal. At the same time, the annular constriction structure can accelerate the water flow and make the water jet height higher. The lower inlet of the water inlet channel 3 is 3D printed with a diverter plate 5, which plays a role in diverting and guiding the flow, dividing the water flow into multiple channels, reducing the mutual influence between water flows, and facilitating the transformation of the water flow from turbulent to horizontal. Through the design of the water inlet channel 3 and the diverter plate 5, the nozzle 1 of this utility model does not need to be equipped with a flow stabilizing valve, reducing the cost of accessories and making installation more convenient.

[0032] There are 2-10 diverter plates 5, which are centrally symmetrically distributed around the inner cone. The lower end of the diverter plate 5 is flush with the bottom of the nozzle 1. There are 2-10 diverter plates 54. Since the water flow entering the nozzle 1 is turbulent, the diverter plates 5 play a role in equalizing and guiding the flow. The multiple water flows after being evenly divided will not disturb each other. After the water inlet channel 3 is closed, it is easier to form a stable horizontal flow so that a water film can be formed at the outlet of the nozzle 1. There is a gap between the upper end of the diverter plate 5 and the annular channel 2 to form a horizontal flow cavity 6. The horizontal flow cavity 6 allows the diverted water flows to converge together and gradually form a horizontal flow. It can also solve the turbulence problem caused by the thickness of the diverter plate 5, so that the water flow entering the annular channel 2 is in a horizontal flow state, ensuring that a stable water film is maintained at the outlet of the nozzle 1.

[0033] The annular flow channel 2 has 12-18 spray holes 21, the specific number of which depends on actual needs. The diameter is 0.4-0.6 cm, so there is no need to worry about shoe heels getting stuck. The distance between adjacent spray holes 21 is no more than 0.4 cm. If the gap is too large, the gap between the water jets from the spray holes 21 will be more obvious, unlike a continuous water jet.

[0034] When the water jet from the direct nozzle 1 reaches a certain height, the water film breaks, forming water splashes that spread outwards. To mimic the water splash effect, the upper ends of the spray holes 21 are all tilted towards the center of the nozzle 1 at an angle of 0.5-1.5°, so that the tips of the water jets from each spray hole 21 converge towards the center and then spread outwards, forming a scattered water splash shape.

[0035] When water enters the annular flow channel 2, it completely transforms into a horizontal flow during the flow process, and a water film forms at the nozzle, making the water column sprayed from the nozzle 21 appear as a transparent water column. Therefore, the height of the annular flow channel 2 should not be too low. As a preferred embodiment, the height ratio of the annular flow channel 2 to the inlet flow channel 3 is 1:1, which ensures the spray height after the inlet flow channel 3 accelerates, and also ensures that a stable water film forms on the surface of the water column sprayed from the inlet flow channel 3, presenting a transparent water column effect.

[0036] Experiments show that the area ratio of the top outlet of the annular flow channel 2 to the bottom inlet of the inlet flow channel 3 is 1:6, which allows the nozzle 1 to spray a higher water column. The taper of the inner cone 4 is 38°, which allows the nozzle 1 to spray a higher transparent water column.

[0037] The nozzle 1, inner cone, and flow divider 5 are integrally formed. The nozzle 1 is made of stainless steel material and is 3D printed as a whole. Through 3D printing technology, the corresponding water flow channel and flow divider 5 can be printed inside the nozzle 1, which is impossible with the original casting technology. Moreover, compared with the tubular fountain nozzle 1 formed by welding and casting, the printed nozzle 1 is cylindrical and can completely fill the nozzle 1 installation opening in the center of the dry ground fountain light panel without leaving gaps or affecting pedestrians. The printed water flow channel can spray water similar to the direct nozzle 1.

[0038] The nozzle 1 of this utility model can be used not only on dry fountains but also as a fountain nozzle 1 in a pool. The outer wall of the nozzle 1 can be threaded, and it can be directly installed on the water outlet of the pool water spray device. The nozzle 1 is a cylindrical structure and can be installed in the center of the light panel of the dry fountain. The surface of the nozzle 1 can be flush with the ground without any protrusions or depressions. Its upper surface has only a ring of small annular water spray holes 21, so even if a woman's high heels sink in, it will not cause any obstruction to people walking. Therefore, it can also be installed and used on dry fountains.

[0039] The above provides a detailed description of the annular cluster fountain nozzle provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, based on the idea of ​​this utility model, there will be changes in the specific implementation and application scope. Changes and improvements to this utility model are possible without exceeding the concept and scope specified in the appended claims. Therefore, the content of this specification should not be construed as a limitation of this utility model.
