[0016] Compared with the prior art, the beneficial effects of this application are:

[0017] This application provides a fountain device and fountain system. The fountain device includes a water spray pipe and a water supply structure. The water spray pipe extends vertically and has an inlet end and an outlet end along its length. The inner wall of the water spray pipe is inclined away from its axis, so that the inner diameter of the water spray pipe gradually increases from the inlet end to the outlet end. The water supply structure is connected to the inlet end and is used to inject water into the water spray pipe so that the water is sprayed from the outlet end and forms a mushroom shape. Because the inner diameter of the water jet pipe is designed to gradually increase from the bottom inlet to the top outlet, the water flow gradually passes through the larger inner diameter pipe, reducing resistance, resulting in a larger volume of water flowing out, smoother flow, and less energy loss during the water flow. Under the action of water pressure, the jet of water can reach a certain height. Furthermore, with a larger volume of water, the distribution of the water flow can be better controlled, preventing the water flow from becoming too concentrated. The water flow can spread out more continuously in all directions, resulting in a continuous arc shape that makes the sprayed water appear mushroom-shaped, thus making the fountain effect more visually appealing.

[0030] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0031] Please see Figure 1 and Figure 2This application discloses a fountain device 100, which includes a water spray pipe 10 and a water supply structure 20. The water spray pipe 10 extends vertically and has an inlet end 10a and an outlet end 10b arranged along its length direction X. The inner wall of the water spray pipe 10 is inclined away from the axis O of the water spray pipe 10, so that the inner diameter of the water spray pipe 10 gradually increases from the inlet end 10a to the outlet end 10b. The water supply structure 20 is connected to the inlet end 10a and is used to inject water into the water spray pipe 10 so that the water is sprayed from the outlet end 10b and forms a mushroom shape.

[0032] The fountain device 100 provided in this application has a water spray pipe 10 extending vertically. The water spray pipe 10 has an inlet end 10a and an outlet end 10b arranged along its own length direction X. The inner wall of the water spray pipe 10 is inclined in a direction away from the axis O of the water spray pipe 10 so that the inner diameter of the water spray pipe 10 gradually increases from the inlet end 10a to the outlet end 10b. Then, the water supply structure 20 is connected to the inlet end 10a to inject water into the water spray pipe 10 so that the water is sprayed from the outlet end 10b. Because the inner diameter of the water jet pipe 10 is set to gradually increase from the bottom inlet 10a to the top outlet 10b, the water flow gradually passes through the pipe with a larger inner diameter, the resistance is reduced, the amount of water flowing out is greater, the water flow is smoother, and the energy loss during the water flow process is also reduced. Under the action of water pressure, the sprayed water can reach a certain water column height. Moreover, with a larger water volume, the distribution of the water flow can be better controlled, avoiding the water flow from being too concentrated. The water flow can spread out more continuously in all directions, effectively ensuring that the shape of the water flow spreading out is a continuous arc surface, so that the sprayed water shape presents a mushroom shape, thereby making the fountain effect more visually appealing.

[0033] In the fountain device 100, the inner diameter of the water spray pipe 10 directly affects the spraying effect and water flow distribution of the fountain. In order to make the sprayed water shape effect better, the inner diameter L1 of the water inlet 10a can optionally be 200mm-250mm, such as 210mm, 219mm, 230mm, etc., and the inner diameter L2 of the water outlet 10b can optionally be 250mm-350mm, such as 280mm, 300mm, 310mm, etc., and the height H of the water spray pipe 10 can optionally be 5m-10m, such as 5m, 6m, 8m, etc. By controlling the inner diameter L2 of the water inlet 10a and the water outlet 10b of the water spray pipe 10 and the height H of the water spray pipe 10 within a reasonable range, not only can the water injection volume of the water spray pipe 10 be reasonably controlled, but also the height of the water column formed by the sprayed water and the degree to which the water shape spreads in all directions can be reasonably controlled, so that the sprayed water shape will not have interruption or the diameter of the top of the water shape is too large or too scattered, which is conducive to improving the spraying effect of the fountain.

[0034] Preferably, the inner diameter L1 of the inlet 10a can be 219mm, the inner diameter L2 of the outlet 10b can be 300mm, and the height H of the spray pipe 10 can be 6m. These dimensions effectively ensure the water volume of the spray pipe 10, resulting in a mushroom-shaped spray pattern. Specifically, the water jet from the outlet 10b first forms a straight column, then spreads outwards at its highest point, creating a mushroom-shaped fountain effect. If the water volume is too small, the sprayed water volume will be too small, failing to meet the height requirement of the straight column and preventing it from spreading outwards. It may even cause the water to spread outwards immediately after exiting the outlet 10b, preventing the fountain from achieving a mushroom shape. Conversely, if the water volume is too large, the sprayed water volume will be excessive, resulting in an overly large diameter at the tip of the water jet and excessive outward spread, causing the water jet to become too scattered and unable to form a continuous arc, thus affecting the visual effect of the fountain.

[0035] Because the inner wall of the water spray pipe 10 is designed as an inclined surface that gradually slopes away from the axis O of the water spray pipe 10 from bottom to top, the water spray pipe 10 takes the form of an inverted cone. This design helps reduce water resistance within the water spray pipe 10, increases water velocity, prevents water stagnation in the pipe, and allows the water to gradually spread during spraying, forming a larger coverage area. However, to prevent the mushroom-shaped water pattern from becoming too large, in some possible embodiments, the angle of inclination of the inner wall of the water spray pipe 10 relative to the axis O of the water spray pipe 10 is 0.3°-0.5°, for example, 0.35°, 0.39°, 0.4°, etc. By reasonably controlling this inclination angle range, the directionality of the water flow is improved without making the water spray area too large. To a certain extent, the water flow tends to be concentrated, allowing the water flow to be sprayed more concentratedly to the desired target area, improving spraying efficiency and resulting in a better mushroom-shaped water pattern.

[0036] Preferably, the angle of inclination of the inner wall surface of the water spray pipe 10 relative to the axis O of the water spray pipe 10 can be 0.39°, and the water spray effect produced by the water spray pipe 10 under this angle design is better.

[0037] See also some possible implementations. Figure 1The water supply structure 20 may include a water pump 21 and a water collection and stabilization tank 22. The water collection and stabilization tank 22 has an inlet 22a and an outlet 22b connected inside the tank. The inlet 22a is connected to the water pump 21, and the outlet 22b is connected to the inlet end 10a. The water collection and stabilization tank 22 is configured to store water and maintain a stable water flow. By setting the water collection and stabilization tank 22 between the water pump 21 and the inlet end 10a of the spray pipe 10, water volume can be stored and the water flow can be stabilized, ensuring that the water flow can be sprayed continuously and evenly through the spray pipe 10, so that the sprayed water flow will not be interrupted or unstable, thereby improving the fountain effect. In addition, the water collection and stabilization tank 22 can also adjust the water flow speed, further enhancing the stable operation and visual effect of the fountain.

[0038] Optionally, the water pump 21 can be a submersible pump or a dry centrifugal pump. When the water pump 21 is a submersible pump, it can be directly installed in the pool of the fountain device 100. Preferably, the water pump 21 can be a submersible pump. Since the submersible pump can be directly installed in the pool of the fountain device 100 and connected to the water collection and stabilization tank 22, water is sprayed through the spray pipe 10 and falls into the pool, where it is directly sucked in and circulated by the submersible pump. In this way, the arrangement can be customized according to the specific needs of the fountain device 100, providing a more flexible arrangement. In addition, the submersible pump has low water consumption, fast start-stop response speed, and low voltage operating characteristics, which is beneficial to meeting the special needs of the fountain device 100, which requires frequent starts.

[0039] It is understandable that the spraying effect presented by the fountain device 100 is not only related to the design and layout of the water pipe 10, but also affected by parameters such as the flow rate and head of the water pump 21. To further improve the spraying effect, the flow rate of the water pump 21 can optionally be 180 m³ / h. 3 / h-220m 3 / h, for example, can be 190m 3 / h、200m 3 / h or 210m 3 The head of water pump 21 can range from 10m to 20m, for example, 13m, 15m, or 17m. A larger flow rate will produce a higher water spray height, and a higher head can lift the water to a higher position. In other words, the water spray height is affected by the flow rate and head of water pump 21. By controlling the flow rate and head of water pump 21 within a reasonable range, it can be ensured that the water spray pattern of fountain device 100 has sufficient height, thus facilitating a better spray effect. Excessive or insufficient flow rate may lead to unstable water spray, or even breakage or splashing, affecting the overall visual effect.

[0040] The power of the water pump 21 affects the operating efficiency and energy consumption. Excessive flow may overload the water pump 21, increasing energy consumption and operating costs, while insufficient flow may not meet the water spraying requirements of the fountain device 100, resulting in poor visual effects. In order to better present the spraying effect, the power of the water pump 21 can be 10KW-15KW, such as 11KW, 13KW, 14KW, etc. By setting the power of the water pump 21 within a reasonable range, the mushroom-shaped water pattern of the fountain device 100 can present a good visual effect while maintaining efficient and stable operation.

[0041] Optionally, the diameter of the water collection and stabilizing tank 22 can be 426mm and the height can be 600mm. The water collection and stabilizing tank 22 with these parameters can store enough water for the full spray and can effectively reduce water flow fluctuations, ensuring a stable water flow into the spray pipe 10. This avoids interruptions or sudden changes in the sprayed water pattern, thereby improving the continuity and visual appeal of the sprayed mushroom-shaped water pattern.

[0042] In some possible implementations, the water pump 21 is connected to the water inlet 22a via an inlet pipe 201, and a check valve 201a is installed on the inlet pipe 201. By installing the check valve 201a on the inlet pipe 201 of the water pump 21, the check valve 201a can prevent water backflow from damaging the water pump 21 or the pipeline when the spraying device stops operating, when the power is suddenly cut off, or when unpredictable weather changes occur. This improves the flexibility of the spraying device in the event of emergencies.

[0043] To provide sufficient jetting power to the fountain device 100, the fountain device 100 may also include an air storage tank 30, which has an air outlet 30a. The water collection and stabilization tank 22 also has an air inlet 22c connected to the inside of the water collection and stabilization tank 22. The air outlet 30a is connected to the air inlet 22c via a connecting pipe 301, and a solenoid valve 301a is installed on the connecting pipe 301. The air storage tank 30 is configured to inject compressed gas into the water flow in the water collection and stabilization tank 22. It can be understood that the air storage tank 30 contains compressed gas, and the water pump 21 delivers water to the water collection and stabilization tank 22. When water spraying is required, the solenoid valve 301a opens, and the compressed gas enters the water collection and stabilization tank 22 through the connecting hose, forcing the water in the water collection and stabilization tank 22 into the water spray pipe 10, which then sprays out a mushroom-shaped water pattern through the water outlet 10b of the water spray pipe 10. By injecting high-pressure airflow into the water collection and stabilization tank 22 through the air storage tank 30, the water pressure is increased, and the water pressure in the water collection and stabilization tank 22 is prevented from suddenly increasing or decreasing, thus maintaining the continuity and stability of the water flow.

[0044] It is understandable that the volume of the air tank 30, as a key component for storing compressed air, may affect the spraying capacity and frequency of the fountain device 100. To ensure the stable operation of the fountain device 100, the air tank 30 can optionally have a diameter of 530mm and a height of 750mm. This specification allows the air tank 30 to provide sufficient compressed air to the spraying device, ensuring the continuity of the fountain device 100's spray and thus enhancing the visual appeal of the mushroom-shaped water spray.

[0045] Optionally, the gas storage tank 30 can be installed vertically or horizontally. Furthermore, the connecting pipe 301 between the gas storage tank 30 and the water collection and stabilization tank 22 can be a metal flexible hose, such as a stainless steel flexible hose. Metal flexible hoses can withstand high pressure and have good flexibility and plasticity, enabling the transmission of compressed gas while making the operation of the fountain device 100 more stable and safe. At the same time, the metal flexible hose can mitigate the effects of impact, vibration, and noise on the fountain device 100, making the fountain device 100 operate more smoothly and extending its service life.

[0046] In some possible implementations, please continue to refer to Figure 1 The central axis of the water collection and stabilization tank 22 can be horizontally set. That is, the water collection and stabilization tank 22 is placed horizontally, with the water inlet 22a located at the bottom of the water collection and stabilization tank 22, and the air inlet 22c and water outlet 22b located on both sides of the water collection and stabilization tank 22 along the direction Y of the central axis of the water collection and stabilization tank 22, and the air inlet 22c and water outlet 22b are located on the same horizontal line. This layout, in which the air inlet 22c and water outlet 22b are located on both sides of the water collection and stabilization tank 22 along the direction Y of the central axis of the water collection and stabilization tank 22, helps to ensure the stable flow of air and water, thereby maintaining the stable operation of the water collection and stabilization tank 22.

[0047] Since the water collection and stabilization tank 22 can adjust the water pressure, the water flow speed inside is slower than the water flow speed in the pipe. In order to stabilize the water pressure, the diameter of the inlet 22a of the water collection and stabilization tank 22 can be smaller than the diameter of the outlet 22b, so that the water flow speed is slowed down, thereby achieving the purpose of stabilizing the water pressure.

[0048] This application also discloses a fountain system, which may include a mounting base (not shown) and a fountain device 100 as described in the first aspect above, with the water jet pipe 10 of the fountain device 100 disposed in the mounting base. Optionally, the mounting base may be a landscape such as a rockery or stone sculpture, and the water jet pipe 10 may be arranged inside these landscapes. The mushroom-shaped water jets from the fountain device 100, combined with these landscape designs, make the fountain system more visually appealing and also enhance the overall environmental quality.

[0049] Optionally, the number of water jets 10 can be multiple, with the mounting base being an arc-shaped acrylic plate, and the multiple water jets 10 spaced apart within the mounting base. By setting the mounting base as an arc-shaped acrylic plate and spaced the multiple water jets 10 along the arc-shaped extension direction within the arc-shaped acrylic plate, which can be set above the ground, the beautiful mushroom-shaped water patterns sprayed from the water jets 10, combined with the aesthetics of the arc-shaped acrylic plate, better highlight the visual effect of the sprayed mushroom-shaped water patterns, thereby improving the viewing effect of the fountain system.

[0050] Optionally, multiple water jets 10 can spray water sequentially in time order, resulting in diverse and dynamic changes in the water patterns. They can also be combined with music or lights to create a completely new visual and auditory experience.

[0051] The fountain device and fountain system disclosed in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the fountain device and fountain system of this application and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
