[0002] With the advancement of urbanization, the importance of urban greening in improving the ecological environment and beautifying the landscape has become increasingly prominent. Especially in areas such as the sides of roads, urban parks and building facades, flower planting can not only improve the overall aesthetics of the city, but also effectively improve air quality and reduce the heat island effect. However, traditional soil cultivation methods have problems such as large land occupation, high maintenance costs, and high water requirements, which are not conducive to promotion and application in large-scale greening scenes.

[0003] In recent years, soilless cultivation technology has gradually attracted attention, among which hydroponic technology has become a new direction for urban greening due to its advantages of being independent of soil, highly controllable, and having high water resource utilization rate. However, most hydroponic systems currently still have certain limitations: for example, in high temperature environments in summer, the roots are easily affected by high temperatures and wither; insufficient oxygenation capacity affects the healthy growth of flowers; at the same time, existing devices usually require high maintenance and operating costs, making it difficult to meet the economic needs of large-scale applications.

[0004] Based on this, a water circulation device for soilless aerial planting of flowers is proposed. Summary of the invention

[0005] The purpose of the invention is to provide a water circulation device for soilless aerial planting of flowers, thereby improving the survival rate of melon and eggplant grafting.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The present invention discloses a water circulation device for soilless aerial planting of flowers, which is composed of a plurality of basic hydroponic modules connected end to end. The basic hydroponic module comprises an inner tube and a temperature-controlled outer tube, and a mounting through hole and a flower fixing net are provided above the inner tube to support the root system of hydroponic flowers. A cooling channel is provided in the outer tube to reduce the temperature by air or flowing liquid to avoid the high temperature in summer affecting the growth of flowers. The oxygenation module and the reflux module are respectively arranged at both ends of the system. The oxygenation module promotes the disturbance of the upper and lower layers of the water flow through the side grooves and impeller design to enhance the oxygenation effect of the water body; the reflux module realizes water circulation through the water level baffle and the reflux opening.

[0028] like Figure 1-Figure 4 As shown, a water circulation device for soilless aerial planting of flowers comprises a plurality of basic hydroponic modules connected end to end, the basic hydroponic module comprises an inner tube 1, a temperature-controlled outer tube 2 is arranged on the outer side of the inner tube 1, a mounting through hole 11 is opened on the top of the inner tube 1, a flower fixing net 3 is installed in the mounting through hole 11, and the flower fixing net 3 is used for supporting the root system of the hydroponic flowers to ensure their stable growth.

[0029] The outer tube 2 is semicircular in shape as a whole, and is provided with a cooling channel 21 therein. An inner tube mounting groove 22 is provided above the outer tube 2 , and the inner tube 1 is arranged in the inner tube mounting groove 22 .

[0030] The inner tube 1 and the outer tube 2 are made of corrosion-resistant high-density polyethylene, which has high mechanical strength and weather resistance. The inner tube 1 and the outer tube 2 can be fixed by snap-fit ​​or threaded connection.

[0031] The outer tube 2 is designed to reduce the temperature of the roots of hydroponic flowers due to the high bottom temperature in the hydroponic system in the summer environment, thereby preventing the hydroponic flowers from withering. The cooling channel 21 of the outer tube 2 reduces the temperature of the outer tube by air circulation or directly setting a flowing liquid to prevent heat accumulation. This design can provide more efficient thermal management, maintain a stable temperature in the hydroponic environment, and ensure the healthy growth of flowers.

[0032] This can provide an effective temperature control solution in urban environments, ensuring that the hydroponic system can operate stably in high summer temperatures.

[0033] Furthermore, the inner tube 1 is provided with a water retaining baffle 12 at every section. The water retaining baffle 12 is to ensure that a portion of water is retained in each section of the inner tube 1 to maintain a stable water level in the hydroponic system. The baffle 12 can be made of corrosion-resistant plastic. By setting up the water retaining baffle 12, it is possible to prevent the water level from being too low to cause the roots of flowers to lack water, ensure a continuous supply of water, and improve the growth efficiency of hydroponic flowers, especially in a high temperature environment, to ensure that the roots will not be damaged due to lack of water. At the same time, it can also reduce the demand for water supply and can be used outdoors over a large area.

[0034] In some disclosures, a limiting boss 31 is provided on the flower fixing net 3, which makes it convenient to take the flower fixing net 3. A planting through hole 33 is provided at the bottom of the flower fixing net 3, and hollow grooves 32 connected to the planting through hole 33 are provided around the planting through hole 33, and the hollow grooves 32 are distributed in a circle. Through such a design, the roots of flowers can be effectively accommodated, and the roots are evenly distributed through the circumferential distribution of the hollow grooves 32, thereby ensuring sufficient absorption by the roots of the plants.

[0035] In some specific embodiments, an oxygenation module 5 and a reflux module 4 are respectively provided at both ends of every few basic hydroponic modules, and water flow baffles 23 are provided on both sides of the outer tube 2 . The oxygenation module 5 is higher than the reflux module 4 .

[0036] The oxygenation module 5 is basically the same as the basic hydroponic module, and also includes an inner tube 1, and a temperature-controlled outer tube 2 is arranged outside the inner tube 1. The outer tube 2 is semicircular as a whole, and water flow baffles 23 are arranged on both sides of the outer tube 2. A cooling channel 21 is arranged inside the outer tube 2, and an inner tube mounting groove 22 is arranged above the outer tube 2. The inner tube 1 has a side groove 52 on the side, and the side groove 52 is located above the plane of the temperature-controlled outer tube 2;

[0037] The top of the inner tube 1 can be designed with an overall opening 51 or can be sealed. The overall opening 51 design can increase oxygen through light, and the sealing setting can avoid water pollution.

[0038] The reflux module 4 is basically the same as the basic hydroponic module, and also includes an inner tube 1, and a temperature-controlled outer tube 2 is arranged outside the inner tube 1. The outer tube 2 is semicircular as a whole, and water flow baffles 23 are arranged on both sides of the outer tube 2. A cooling channel 21 is arranged inside the outer tube 2, and an inner tube mounting groove 22 is arranged above the outer tube 2. The inner tube 1 is arranged in the inner tube mounting groove 22. A reflux opening 42 is opened at one end of the inner tube 1 close to the oxygenation module 5, and a water level baffle 41 is arranged on the end face of the outer tube 2 close to the oxygenation module 5.

[0039] Through such a design, the coordinated work of the oxygenation module 5 and the reflux module 4 can greatly improve the oxygen supply and water circulation efficiency of the hydroponic system. The oxygenation module 5 guides the water flow into the plane of the outer tube 2 through the side groove 52, increases the contact area between the water flow and the air, and effectively promotes the increase of dissolved oxygen in the water by means of light and natural ventilation, thereby providing sufficient oxygen support for the flowers and avoiding poor plant growth caused by root hypoxia. The water flow baffle 23 can effectively guide the water flow to prevent it from overflowing to both sides, and at the same time avoid uneven oxygen supply caused by too fast water flow. The reflux module 4 ensures that the water flow converges smoothly through the setting of the water level baffle 41, and introduces the water flow into the inner tube 1 through the reflux opening 42 to achieve continuous circulation of the water flow, thereby reducing the waste of water resources and maintaining the stability of the hydroponic environment.

[0040] Furthermore, a mounting mesh plate 53 is provided in the inner tube 1 of the oxygenation module 5, and an impeller 54 is installed on the mounting mesh plate 53, so that the water flow in the inner tube 1 drives the impeller 54 to move, thereby disturbing the water body in the upper and lower layers. The beneficial effect of this design is that the water flow in the inner tube 1 is not only the upper layer of water guided to the plane of the outer tube 2, but also the upper and lower layers of water flow can fully contact with the air, thereby enhancing the uniformity of the water flow and the oxygen exchange efficiency.

[0041] Furthermore, a plurality of linearly distributed bosses 24 are provided on the plane of the outer tube 2. The linear distribution design of the bosses 24 can guide the water flow along a specific path and form local eddies and waves when the water flows through the bosses. This ripple effect can significantly prolong the contact time between the water flow and the air, promote the diffusion of oxygen into the water body, and increase the concentration of dissolved oxygen in the water. At the same time, the formation of ripples can also break the surface tension of the water surface, further improving the oxygen exchange efficiency.
