Description

Technical Field

[0001] This utility model relates to the field of plant cultivation technology, and more specifically, to a hydroponic hybrid cultivation device. Background Technology

[0002] With societal development, traditional agricultural planting methods can no longer meet the needs of modern life. Soilless cultivation is an important cultivation method in modern agriculture. Aeroponics and hydroponics are two typical soilless cultivation models. Hydroponics involves immersing plant roots in a nutrient solution for growth; aeroponics uses a spraying device to atomize the nutrient solution into small droplets, which are then sprayed directly onto the plant roots to provide the water and nutrients needed for plant growth. Existing aeroponic cultivation has the problem that while the ultra-small droplet size of the liquid is beneficial for plant nutrient absorption, the supply is insufficient; hydroponics, on the other hand, suffers from insufficient oxygen absorption by the roots.

[0003] Devices that combine aeroponics and hydroponics, two soilless cultivation methods, have now been developed.

[0004] Chinese patent CN 210352537 U discloses a device that can be used for both hydroponics and aeroponics. It includes a water supply component, a water return component, a misting nozzle, a cultivation trough, a cultivation trough cover, a planting component, a planting cup, and a water storage tank. The water supply component includes a hollow pipe and an annular connector. The misting nozzles are evenly mounted on the annular connector, and the water supply component is located in the center of the water return component. The water return component includes a riser and a funnel body located at the upper end of the riser. Multiple partitions are provided in the riser, with first and second through holes at the upper and lower ends of each partition. A third through hole is provided at the bottom of the water return component. The water return component is placed in the center of the cultivation trough. The cultivation trough cover is placed at the upper end of the cultivation trough and inside the water storage tank. The planting component is placed at the upper end of the funnel body, and planting holes are evenly distributed on the surfaces of the cultivation trough cover and the planting component. The planting cup is placed inside the planting hole. The water storage tank contains nutrient solution. However, this device is large and inconvenient to use, and the atomization device cannot achieve optimal results.

[0005] Chinese patent CN 203105262 U discloses a water mist vegetable rack, including a liquid storage tank, an infusion pipe, and a water pump. The top of the liquid storage tank is equipped with a water mist sealed cylinder, and the infusion pipe is vertically installed inside the water mist sealed cylinder. The top of the water mist sealed cylinder is equipped with a top cover composed of multiple flat-bottomed vegetable aeroponic containers. The side wall of the water mist sealed cylinder has multiple layers of aeroponic containers arranged vertically, each containing a mist-absorbing sponge for planting. The infusion pipe has three or more atomizing nozzles spaced apart on its wall. Water mist is sprayed from these nozzles, some of which is absorbed by the mist-absorbing sponge, while the rest falls into the liquid storage tank. This device also suffers from being large in size, inconvenient to use, and unable to ensure sufficient light and root nutrients for the plants.

[0006] Chinese patent CN102638969 A discloses a device for growing and developing plants using aeroponics, including a container for holding liquid nutrient solution, a conical tower, a power source, and a pump to move the liquid nutrient solution through the device. The device uses the pump to move the liquid nutrient solution vertically from the container to a distribution pipe. Gravity then pulls the liquid nutrient solution downwards through the distribution pipe, the opposite end of which is sealed. The pressure generated within the distribution pipe is sufficient to disperse the liquid nutrient solution through openings on the pipe onto the exposed root system. The conical tower structure of this device has the problems of high production costs and reduced planting capacity; furthermore, although it moves the liquid nutrient solution to the top via the pump, the form and manner of supplying the nutrient solution to the plant roots from top to bottom makes absorption difficult. Additionally, this device only achieves the supply of liquid nutrient solution and does not simultaneously realize hydroponics / aeroponics.

[0007] Therefore, there is a need for aeroponics / hydroponics hybrid planting equipment that can solve the above problems. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] The preferred embodiment of the urban aeroponic / hydroponic hybrid planting equipment of this utility model is as follows: Figure 1 As shown, see also Figures 2-5The system includes a column 1 with a channel 11 running from top to bottom inside. The upper end of the column 1 is connected to an upper water supply chamber 31 and an upper nutrient solution chamber 32, while the lower end is connected to a lower water supply chamber 51 for water storage and a lower nutrient solution chamber 61 for nutrient solution storage. The upper nutrient solution chamber 32 contains an atomizer 7 for atomizing the nutrient solution. A planting column 2 is fitted around the outside of the column 1, with a gap between the inner wall of the planting column 2 and the outer wall of the column 1 to form a water mist chamber S1. The roots of the plants planted on the planting column 2... The plant is exposed inside the water mist chamber S1. The lower water supply chamber 51 and the lower nutrient solution chamber 61 are connected to a power unit, which includes a water pump 91 and a nutrient solution pump 92, to transport the water in the lower water supply chamber 51 and the nutrient solution in the lower nutrient solution chamber 61 through the channel 11 to the upper water supply chamber 31 and the upper nutrient solution chamber 41, respectively. The upper water supply chamber 31 and the upper nutrient solution chamber 41 are both connected to the water mist chamber S1, so that the water transported to the top and the atomized nutrient solution are simultaneously scattered to the plant roots through the water mist chamber S1 under the action of gravity.

[0033] This equipment utilizes a hollow column 1 to connect upper and lower water supply chambers and upper and lower nutrient solution chambers. A water mist chamber S1 is installed between the planting column 2 and the column 1. Since both the upper water supply chamber and the upper nutrient solution chamber are connected to the water mist chamber S1, the water transported from the middle channel 11 of the column 1 to the top and the atomized nutrient solution are simultaneously dispersed to the plant roots through the water mist chamber S1 under gravity. This completes the circulation of clean water and nutrient solution while avoiding the problem of insufficient oxygen absorption at the plant roots. Furthermore, the overall columnar shape of this equipment enables vertical, three-dimensional planting, maximizing space utilization and improving planting efficiency. It is suitable for use on balconies, windowsills, in homes, offices, and shops. This equipment combines aeroponics and hydroponics, solving the problems of insufficient nutrient supply in aeroponics due to the ultra-small mist diameter, and insufficient oxygen absorption at the roots in hydroponics.

[0034] It should be noted that the above-mentioned water mist chamber S1 is located between the column 1 and the planting column 2, and the water mist chamber S1 extends from the upper end to the lower end inside the planting column 2. It can be seen that the water mist chamber S1 is an independent space completely isolated from the internal space of the column 1, so that water and atomized nutrient solution can be simultaneously dispersed to the plant roots through the water mist chamber S1 under the action of gravity, without being obstructed by the upward liquid inside the column 1.

[0035] In a further embodiment, a buffer chamber is provided between the upper water supply chamber 31 and the upper nutrient solution chamber 41 of the aforementioned urban aeroponic hydroponic composite planting equipment and the water mist chamber S1 to facilitate thorough mixing of water and atomized nutrient solution. The buffer chamber S1 is connected to both the upper water supply chamber 31 and the upper nutrient solution chamber 41, and also to the water mist chamber S1; by providing a buffer chamber to simultaneously connect the upper water supply chamber 31 and the upper nutrient solution chamber 41, the incoming clean water and nutrient solution mist can be mixed more evenly here.

[0036] In a further embodiment, the above-mentioned urban aeroponic hydroponic composite planting equipment also includes a rotary motor 74 for driving the planting column 2 to rotate. The rotary motor 74 is drivenly connected to the planting column 2 and drives the planting column 2 to rotate through a rotary linkage unit. The rotary motor 74 is mounted on a mounting plate 75, which is located above the planting column 2. The lower ends of the upper water supply chamber 31 and the upper nutrient solution chamber 41 are respectively provided with grooves 76. The mounting plate 75 covers the grooves 76 and together with the grooves 76 forms the above-mentioned buffer chamber.

[0037] In a further embodiment, one or more openings 78 communicating with the water mist chamber S1 are provided on the mounting plate 75. By changing the diameter and number of openings 78, the overall water output rate and mist output rate in the water mist chamber S1 can be easily controlled.

[0038] In a further embodiment, the upper water supply chamber 31 and the upper nutrient solution chamber 41 of the above-mentioned urban aeroponic hydroponic composite planting equipment are located in the upper left shell 3 and the upper right shell 4, respectively. The upper left shell 3 and the upper right shell 4 are detachably set at the upper end of the column 1, and the detachable structure facilitates the disassembly and assembly of the equipment.

[0039] Specifically, the upper left shell 3 and the upper right shell 4 can be detachably connected to the upper end of the column 1, which facilitates the overall installation and transportation of the equipment.

[0040] Preferably, the upper left shell 3 and upper right shell 4 of the aforementioned urban aeroponic hydroponic composite planting equipment are interlocked and connected to the upper end of the column 1, and the corresponding splicing surfaces of the two shells are provided with structures for clamping, fixing or limiting the upper end of the column 1. The lower left shell 5 and lower right shell 6 are interlocked and connected to the upper end of the column 1, and the corresponding splicing surfaces of the two shells are provided with structures for clamping, fixing or limiting the lower end of the column 1.

[0041] In a further embodiment, the upper left shell 3 of the aforementioned urban aeroponic hydroponic composite planting equipment is equipped with a cooling component 8 for water cooling the water supply pipe and a temperature sensor for detecting the temperature of the water outlet from the water supply pipe. The cooling component 8 is used to cool the water supply pipe, and a portion of the water supply pipe passing through the cooling component 8 passes through the nutrient solution in the upper nutrient solution chamber 41. The cooling component 8 starts operating when the temperature sensor detects that the temperature is higher than a set value. This design can prevent the water temperature from becoming too high and can cool it down in time to ensure the needs of plant growth. While the cooling component cools the water, the water supply pipe passing through the nutrient solution in the upper nutrient solution chamber also cools the nutrient solution, reducing the temperature of the nutrient solution mist.

[0042] In a further embodiment, the upper left shell 3 and / or upper right shell 4 of the above-mentioned urban aeroponic hydroponic composite planting equipment are provided with light-emitting units 73, which can serve functions such as aesthetics and illumination; the light-emitting units 73 can be LED beads, LED panels, etc., and there is no limitation on them.

[0043] When the rotary motor 74 is running, it drives the planting column 2 to rotate through the rotary linkage unit, which makes the plants receive light more evenly. The rotary linkage unit can use a belt drive or other transmission methods such as gears, and there is no limitation on it.

[0044] In a further embodiment, the planting column 2 of the aforementioned urban aeroponic / hydroponic hybrid planting equipment is composed of multiple hollow planting chambers 21 assembled together. These hollow planting chambers 21 can be detachably connected or formed as a single, integral structure. The hollow planting chambers 21 can be standard parts with identical dimensions and shapes, or they can be structures of varying sizes. The number and size of the planting chambers 21 determine the overall height of the equipment. Therefore, different models of equipment can be produced by adjusting the number and size of the planting chambers 21 to meet the needs of different users.

[0045] In a preferred embodiment, the plurality of hollow implant chambers 21 can be standard parts with identical dimensions and shapes, such as... Figure 1 and Figure 2 As shown, they are strung together like a skewer of candied hawthorns. Each planting chamber 21 includes an upper connecting end and a lower connecting end, as well as a planting frame located in the middle. The planting frame includes an upper surface and a lower surface that are inclined relative to the axis of the main body and are connected to form a folded surface, roughly like a flying saucer shape. Multiple planting holes 211 are provided on the upper surface, which communicate with the water mist chamber S1 so that the roots of the plants are exposed in the water mist chamber S1 to fully absorb water and nutrient solution.

[0046] In a further embodiment, the above-mentioned urban aeroponic hydroponic composite planting equipment also includes at least one seedling chamber Y for seedling cultivation, and the seedling chamber Y is located at the bottom of the planting column 2.

[0047] When multiple seedling chambers Y are set up, the multiple seedling chambers Y are distributed longitudinally; the seedling chambers Y are located between the planting column 2 and the lower water supply chamber 51; the seedling chamber Y includes a seedling tray Y2 and an outer shell Y1; the outer shell Y1 includes a detachably connected left half shell and a right half shell; the upper end of the outer shell Y1 is provided with a water inlet hole and the lower end is provided with a water outlet hole; the seedling tray Y2 is provided with one or more holes; the water passing through the seedling chamber Y flows back to the lower water supply chamber 51; with this design, the equipment has the ability to assist germination, and can supply clean water and nutrient solution mist during germination to improve germination efficiency.

[0048] In summary, this equipment utilizes vertical, three-dimensional planting to maximize space utilization and improve planting efficiency. It combines aeroponics and hydroponics, solving the problems of insufficient nutrient supply in aeroponics due to the ultra-small mist diameter, and insufficient oxygen absorption by roots in hydroponics. It also facilitates the adjustment of nutrient concentrations required by plants at different stages and allows for effective control of nitrite content in harvested vegetables, promoting food safety. The temperature control system ensures plants grow in the optimal temperature environment. It is suitable for use on balconies, windowsills, in homes, offices, shops, and other similar locations.

[0049] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
