Description

Technical Field

[0001] This utility model relates to fountain equipment, and more particularly to a tulip-shaped water spray 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 divided into dry fountains and pool fountains according to their location. Dry fountains, because they are placed on the ground and need to be accessible to pedestrians, have nozzles that are basically flush with the ground. Therefore, the location limits the functional design of the nozzles. As a result, the flow channel inside the nozzles of existing dry fountains only has one water jet, which can only spray water jets. It is necessary to use nozzles at different angles to create a combination of water jets for the performance.

[0004] Pool fountains, through the combined design of their internal structure and external shape, can create fountain channels that can spray various fancy water patterns. Compared to dry fountains, pool fountains produce a wider variety and more visually appealing water patterns. Combinations of these patterns with music and lighting effects allow for more diverse performance styles. However, a drawback is that the nozzles are large and irregularly shaped, posing a tripping hazard to pedestrians if installed on the ground. Therefore, they are only suitable for use in pools.

[0005] 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, providing a new direction for the development of the fountain industry. Therefore, our company has combined the advantages of dry fountains and pool fountains to design a brand-new fountain nozzle. Utility Model Content

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

[0029] Example: This utility model discloses a tulip-shaped water spray nozzle, see [link / reference]. Figures 1 to 4 A tulip-shaped water spray nozzle includes a cylindrical nozzle 1, which consists of an inner cone, an outer cylinder 2, and a flow divider 4. The flow divider 4 is located at the lower part of the nozzle 1, and the inner cone is located at the center of the nozzle 1 and is fixedly connected to the outer cylinder 2 through the flow divider 4. The inner wall of the outer cylinder 2 has a scaling structure that first contracts and then expands from bottom to top. The inner cone has a cone-shaped structure that is smaller at the bottom and larger at the top. A flow channel 5 is formed between the inner cone and the outer cylinder 2. To produce a tulip-shaped spray of water, this invention designs the flow channel 5 within the nozzle 1. Water enters from the bottom of the nozzle 1 and converges within the tapering section of the inner cone and outer cylinder 2. The inclined outer wall of the outer cylinder 2 and the outer wall of the inner cone stabilize the turbulent water flow. After converging, the water flows towards the constriction 51, where it is accelerated, increasing the spray height. After acceleration at the constriction 51, the water enters the expanding section at the top of the inner cone and outer cylinder 2, where it flows smoothly upwards, resulting in a more stable water film. The water film is higher, and its conical design can form a trumpet-shaped water film at the nozzle 1 outlet, just like tulip petals. When sprayed to a certain height, the water film will break and collide with the water flow below to form water droplets that disperse in all directions, just like blooming tulips. The nozzle 1 of this utility model can spray fancy water patterns like a pool fountain. Moreover, it is simple and convenient to process and manufacture, and its size is smaller. It can be used in both pool fountains and dry fountains. Its surface will not have any protrusions and will not obstruct pedestrians. It solves the problem of the single water spray pattern of dry fountains.

[0030] Depending on the change of water supply mode, the fancy nozzle 1 of this utility model can present different display effects:

[0031] When the water supply is stable: the water flow gradually increases from 0 to the set value. During this time, the flower shape change process of nozzle 1 is as follows: water is emitted from nozzle 1, and the petal-shaped water film gradually rises. When it reaches a certain height, the water film opens up, and the continuously sprayed water below disperses the water droplets, just like a continuously blooming flower. (See below) Figure 5 .

[0032] When using frequency conversion control: the water supply fluctuates cyclically from 0 to the set value and back to the set value. During this cycle, the spray pattern of nozzle 1 changes as follows: the petal-shaped water film gradually rises, closes at a certain height, and then falls. This process repeats itself, like an unopened tulip flower. (See [link to relevant documentation]). Figure 6 .

[0033] Solenoid valve control: The water supply cycle changes from 0-set value-off-0-set value-off. During this cycle, the spray pattern of nozzle 1 changes as the petal-shaped water film gradually rises and spreads outwards upon reaching a certain height. Because the solenoid valve's shut-off has a time interval, there is a noticeable break at the base of the water pattern 6. The entire water pattern 6 resembles a tulip blooming in the air. (See also...) Figure 7 .

[0034] The nozzle 1 of this utility model is made of stainless steel material by 3D printing. Through 3D printing technology, the corresponding water shape 6 flow channel 5 can be printed inside the nozzle 1. Compared with the water fountain nozzle 1 formed by welding and casting, it is smaller in size. Its shape can be printed into a columnar structure like the welded nozzle 1, which will not affect pedestrians. It can also spray out fancy water shapes 6, which is more beautiful than the welded nozzle 1.

[0035] The taper of the upper expansion port of the outer cylinder 2 is the same as that of the inner cone, and a stable flow channel 5 structure is formed between the outer cylinder 2 and the inner cone, which can form a stable water film at the outlet of the nozzle 1.

[0036] The minimum constriction 51 of the flow channel 5 should not be too high. If it is too high, the expansion section may not be able to form a stable water film. If it is too low, the spray nozzle speed may be too low, and it may not be able to spray to the ideal height. The specific height depends on the actual situation. As a preferred option, the minimum constriction 51 of the flow channel 5 is located in the upper middle part of the nozzle 1, which can be as close as possible to the outlet of the nozzle 1 to ensure the spray height after acceleration and to ensure that the expansion nozzle can form a stable water film.

[0037] The lower end of the diverter plate 4 is flush with the bottom of the nozzle 1, and the upper end is located in the middle of the nozzle 1. There are 2-10 diverter plates 4, which are centrally symmetrically distributed with the inner cone as the center. Since the water flow entering the nozzle 1 is turbulent, the diverter plate 4 plays a role in dividing and guiding the flow. The multiple water flows after being divided will not disturb each other. After being guided and narrowed by the inner cone and the outer cylinder 2, it is easier to form a stable horizontal flow so that a water film can be formed at the outlet of the nozzle 1. The upper end of the diverter plate 4 is located in the middle of the nozzle 1, and there is a gap between it and the minimum narrowing 51 so that the divided water flows can converge together to form a gradually forming overall horizontal flow. This solves the turbulence problem caused by the thickness of the diverter plate 4, and ensures that the water flow entering the narrowing 51 is in a horizontal state, ensuring that a stable water film is maintained at the outlet of the nozzle 1.

[0038] The connection between the flow divider 4 and the inner cone, as well as the connection between the flow divider 4 and the inner cylinder, are all rounded to reduce turbulence caused by the angle of the connection.

[0039] Based on the experimental results, as a preferred embodiment, the bottom inlet and top outlet of the flow channel 5 are both annular, and the area ratio of the inlet to the outlet is 5:3. The taper of the upper expansion and lower contraction of the inner wall of the outer cylinder 2 is 70-85°. At this time, the water spray pattern 6 of the nozzle 1 is optimal.

[0040] The nozzle 1 can have a threaded opening on its outer wall, and can be directly installed on the water outlet of the water spray device in the pool. The upper and lower surfaces of the inner cone of the nozzle 1 are flush with the upper and lower surfaces of the outer cylinder 2, forming a columnar structure. It 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 water nozzles, so even if a woman's high heels sink in, it will not cause any obstruction to people walking. It can be installed and used on dry fountains.
