Description

Aeroponics device with multi-channel nozzles The present invention relates to an aeroponics device comprising a multi-channel nozzle, and more specifically, to an aeroponics device comprising a multi-channel nozzle that supplies various elements and trace elements necessary for plant growth by appropriately mixing them through a modularized nutrient cartridge according to the type or growth state of the plant. In traditional soil cultivation, most of the water sprayed onto the soil seeps into the soil and underground layers, failing to be fully absorbed by plant roots, which can lead to water waste and soil pollution. To address these issues, hydroponic cultivation methods such as deep water and drip systems were introduced, in which crops are anchored in a soilless environment and their roots are immersed in a nutrient solution dissolved at appropriate concentrations according to the absorption rates of essential elements required for growth. However, hydroponic cultivation presented a problem in that the weight of the water necessitated high costs depending on the scale of the facility. Aeroponics is a cultivation technique that sprays a nutrient solution mist onto plant roots for direct absorption. It has the advantage of not only reducing water usage but also lowering facility costs compared to hydroponics. Conventional aeroponics can aid plant growth using minimal nutrient usage by spraying nutrients through nozzles with fine orifices. However, conventional aeroponics has a fatal drawback. When cultivating plants using aeroponics, various nutrients (especially essential nutrients) may be supplied through nozzles. If multiple nutrient solutions are mixed and sprayed through the nozzles, they can react with each other to form solid precipitates, which can lead to nozzle clogging. In this case, if a single nozzle becomes clogged or remains clogged for an extended period, the plants produced in that growth module cannot be harvested. Furthermore, the clogging of a single nozzle can result in the inability to harvest an entire plant. In other words, since aeroponics supplies small amounts of water and nutrient solutions to plant roots in the form of mist particles, it is absolutely essential to prevent nozzle clogging. Meanwhile, in all agricultural and hydroponic systems, various fertilizers (essential nutrients) are supplied according to plant growth and environmental conditions. Consequently, if crop yields decline or nutrient deficiencies occur, the need to use multiple fertilizers leads to increased production costs. In particular, in aeroponics, "negative effects" between essential nutrients can occur, inhibiting plant nutrient absorption by disrupting optimal absorption environments (EC, pH), which can result in growth disorders. Furthermore, the phenomenon of solidification caused by chemical entanglement between nutrients can lead to clogging of the nozzles supplying water and nutrients, potentially causing significant damage.
