Description

Technical Field

[0001] This utility model relates to fountain equipment, and more particularly to a butterfly-wing-shaped 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 into dry-land fountains and pool fountains based on their application location. They can also be classified by their spray pattern, such as direct-shot nozzles, diffuser nozzles, rotating nozzles, and fan-shaped nozzles. The wing-shaped nozzle is a variation of the diffuser nozzle, using two flat nozzles to spray water outwards. Because of the flat nozzles, the spray is not a cylindrical jet of water but rather a water curtain of a certain width, resembling transparent wings. With variable frequency water supply, it looks like a pair of butterfly wings flapping. Whether in a dry-land fountain or a pool fountain, because two flat nozzles are required for combined use, and the nozzles need to form a stable water film on the surface of the spray, this cannot be achieved through openings. Instead, two flat nozzles tilted to the sides must be designed at the top of the nozzle's water chamber. This protruding nozzle structure can easily cause pedestrians to trip, making it unsuitable for dry-land fountains. Therefore, this water shape can only be seen in pool fountains.

[0004] The disadvantages of existing wing-shaped water nozzles are:

[0005] 1. Because existing nozzles are all tubular castings, they require structural design of the overall shape to form a stable water flow channel inside, which results in a large volume. Therefore, the nozzles of pool fountains cannot be designed to be hidden, affecting their aesthetics.

[0006] 2. Although the nozzles of dry fountains can be parallel to the ground and designed to be hidden, many water-shaped nozzles require a protruding nozzle structure to form a flow channel. Therefore, dry fountains cannot currently achieve this and can only perform conventional water jet spraying.

[0007] However, with the maturity of 3D printing technology, fountain nozzles that could only be formed by casting in the past can now be manufactured by 3D printing, and the internal flow channels of the nozzles can be printed, providing a new direction for the development of the fountain industry. Utility Model Content

[0008] The purpose of this invention is to provide a butterfly-wing-shaped fountain nozzle that solves the above-mentioned problems.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is: a butterfly-wing-shaped fountain nozzle, comprising a nozzle that is a solid cylindrical structure with a flat top surface. The nozzle has two independent flow channels 3D-printed inside, each flow channel consisting of flow channel A and flow channel B. Flow channel A consists of an upper water outlet flow channel A and a lower water inlet flow channel A, and flow channel B consists of an upper water outlet flow channel B and a lower water inlet flow channel B. The upper water outlet channel A and the upper water outlet channel B are flat. The upper water outlets of the upper water outlet channels A and B are staggered. The lower water inlets of the upper water outlet channels A and B are symmetrically arranged and are connected to the lower water inlet channels A and B respectively. The lower water inlet channels A and B are semi-conical structures with a smaller upper section and a larger lower section. The lower water inlet channels A and B are symmetrically arranged.

[0010] Preferably, a partition structure is formed between flow channel A and flow channel B, and the cross-section of the partition structure is conical with a taper of 5-6°.

[0011] Preferably, the upper ends of the upper water outlet channel A and the upper water outlet channel B are inclined to the front and rear sides respectively, and the inclination is consistent with the inclination of the outer side of the partition structure.

[0012] Preferably, the upper ends of the upper water outlet channel A and the upper water outlet channel B are inclined to the left and right sides respectively, with an inclination of 4°.

[0013] Preferably, the top of the upper water outlet channel A and the upper water outlet channel B are the water outlets of the nozzle, and the bottom of the lower water inlet channel A and the lower water inlet channel B are the water inlets of the nozzle, with the area ratio of the water outlet to the water inlet being 1:5.

[0014] Preferably, the connection surface between the inlet of the lower water inlet channel A and the upper water outlet channel A is an arc-shaped transition surface, and the connection surface between the inlet of the lower water inlet channel B and the upper water outlet channel is an arc-shaped transition surface.

[0015] Preferably, the height ratio of the upper water outlet channel A to the lower water inlet channel A is 5:4, and the height ratio of the upper water outlet channel B to the lower water inlet channel B is 5:4.

[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 uses 3D printing to print the flow channel, so that the top of the nozzle can be designed as a flat plane. When pedestrians walk and play on it, they will not be tripped, which greatly improves safety. It can be used not only on dry fountains, but also on pool fountains. By combining the two flow channels A and B, a water jet like butterfly wings can be formed.

[0019] (2) The upper water outlet channel A and the upper water outlet channel B are designed in a flat shape, so that the water sprayed from the upper water outlet of the nozzle is a transparent ribbon. When the water is sprayed at the highest point, it can form a water curtain of a certain width, making the water shape more like wings. When the frequency conversion water supply is carried out, the water supply is a cyclic water supply of 0-set value-0. Its water shape is like the flapping of butterfly wings, and it is crystal clear and even more beautiful with the light.

[0020] (3) By designing the semi-conical structure of the lower water inlet channel A and the lower water inlet channel B, this utility model ensures the maximum water intake while distributing the water intake equally to channel A and channel B, so that the water intake on both sides is the same and the spray height is the same. Due to the conical structure, the water flow is accelerated as the diameter gradually decreases, thereby increasing the spray height. At the same time, it guides the water flow, so that the turbulence in the water flow gradually changes to a horizontal state, ensuring that the surface of the water flow sprayed from the upper outlet of the nozzle can form a transparent water film, making the water more crystal clear.

[0029] The present invention will be further described below.

[0030] Example: A butterfly-wing-shaped water fountain nozzle, see [link / reference] Figures 1 to 7 The device includes a nozzle 1, which is a solid cylindrical structure with a flat top surface. Due to the use of 3D printing for the flow channel, the flow channel has an inherent tilt angle and water flow stabilization effect, allowing the top of the nozzle 1 to be designed as a flat plane. Not only is it small in size and can be used in pool fountains, but its flat surface also allows it to be hidden in dry fountains, preventing pedestrians from tripping over it and greatly improving safety.

[0031] To achieve the desired butterfly-shaped water jet, the flow channels within nozzle 1 were designed. Nozzle 1 contains two independent 3D-printed flow channels, consisting of flow channel A2 and flow channel B3. The combination of these two flow channels creates a butterfly-wing-like water jet. Flow channel A2 consists of an upper outlet flow channel A21 and a lower inlet flow channel A22, while flow channel B3 consists of an upper outlet flow channel B31 and a lower inlet flow channel B32.

[0032] The upper water outlet channels A21 and B31 are flat. This design, by making the upper water outlet channels A21 and B31 flat, allows the water stream from the upper outlet 4 of the nozzle 1 to form a transparent ribbon. When the water stream is sprayed at its highest point, it forms a water curtain of a certain width, making the water shape resemble wings. By staggering the upper outlets 4 of the upper water outlet channels A21 and B31, when the water stream is sprayed at an angle to the left and right, its shape resembles a pair of wings. During variable frequency water supply, the water supply is a cyclical supply of 0-set value-0, and the water shape resembles fluttering butterfly wings, and is crystal clear, making it even more beautiful when combined with lighting.

[0033] The lower inlets 5 of the upper water outlet channel A21 and the upper water outlet channel B31 are symmetrically arranged and are respectively connected to the lower water inlet channel A22 and the lower water inlet channel B32. The lower water inlet channel A22 and the lower water inlet channel B32 are semi-conical structures with a smaller upper part and a larger lower part. The lower water inlet channel A22 and the lower water inlet channel B32 are symmetrically arranged. This invention, through the semi-conical structure design of the lower water inlet channel A22 and the lower water inlet channel B32, ensures the maximum water intake while evenly distributing the water into channels A2 and B3, making the water intake on both sides the same and the spray height the same. Due to the conical structure, the water flow is accelerated as the diameter gradually decreases, thereby increasing the spray height. At the same time, it guides the incoming water flow, causing the turbulence in the water flow to gradually change into a horizontal state, ensuring that the water flow sprayed from the upper outlet 4 of the nozzle 1 can form a transparent water film on the surface, making the water more crystal clear.

[0034] Since flow channels A2 and B3 are independent of each other and will not affect each other, a partition structure 6 will be formed between flow channels A2 and B3 after printing. The cross-section of the partition structure 6 is conical with a taper of 5-6°. The inclined design of the partition structure 6 serves two purposes: first, to smoothly guide the water flow in the lower inlet flow channels A22 and B32 to the upper outlet flow channels A21 and B31, achieving a smooth transition; and second, to form a tapered conical structure in the lower inlet flow channels A22 and B32, guiding the turbulent flow to transition to advection. Because the outlet 4 is flat and easily affected by wind, the water flow from the two outlets 4 may become intertwined. Therefore, the upper ends of the upper water outlet channel A21 and the upper water outlet channel B31 are inclined to the front and rear sides respectively, and the inclination is consistent with the inclination of the outer side of the partition structure 6. This not only forms a perfect connection with the partition structure 6 of the lower water inlet channel A22 and the lower water inlet channel B32, but also makes the water flow from the outlet 4 inclined to the front and rear sides, so that the water flow from the two outlets 4 is less likely to become intertwined.

[0035] The upper ends of the upper water outlet channels A21 and B31 are inclined to the left and right sides respectively, with an inclination of 4°, so that the two water outlets 4 at the top of the nozzle 1 spray water in a butterfly shape to the left and right sides.

[0036] Through experiments, the tops of the upper water outlet channels A21 and B31 serve as the water outlets 4 of the nozzle 1, and the bottoms of the lower water inlet channels A22 and B32 serve as the water inlets 5 of the nozzle 1. The area ratio of the water outlets 4 to the water inlets 5 is 1:5, which results in a better spray height effect.

[0037] The connection surface between the inlet 5 of the lower water inlet channel A22 and the upper water outlet channel A21 is an arc-shaped transition surface. The connection surface between the inlet 5 of the lower water inlet channel B32 and the upper water outlet channel is an arc-shaped transition surface. The arc-shaped transition surface and the partition structure 6 form a tapering structure, which can realize the transformation of water flow from turbulent flow to horizontal flow and accelerate the spraying out from the outlet 4 of the nozzle 1.

[0038] Although the gradually narrowing inlet channel can facilitate the transition of water flow from turbulent to horizontal flow, the water entering the outlet channel still exhibits turbulence, affecting the formation of the water film. Since the turbulent water flow also transitions to horizontal flow within the outlet channel, the length design of the outlet channel is particularly important. If the outlet channel is too long, it leads to wasted space and insufficient space in the inlet channel. If the outlet channel is too short, it cannot ensure that the turbulence completely transitions to horizontal flow within the outlet channel, affecting the water film effect at outlet 4. The optimal effect is achieved when the height ratio of the lower inlet channel A22 to the upper outlet channel A21 and the lower inlet channel A22 is 5:4, and the height ratio of the upper outlet channel B31 to the lower inlet channel B32 is also 5:4.

[0039] The nozzle 1 is made of stainless steel and is 3D printed as a whole, which has high structural strength and is not easy to rust.

[0040] The nozzle 1 of this invention can be used not only on dry fountains but also as a fountain nozzle 1 in a pool. The nozzle 1 has a threaded outer wall, allowing it to be directly installed on the water outlet 4 of a pool fountain device. Without protruding nozzles, it does not affect the aesthetic appearance and can be designed for concealment. The nozzle 1 is a cylindrical structure that can be installed in the center of the light panel of a dry fountain. Its top surface is flush with the ground, without any protrusions or depressions. Its upper surface has only two elliptical water outlets 4, which will not obstruct pedestrian movement, thus it can also be installed and used on dry fountains.

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.
