Problems solved by technology

As the key core component of the aerosol culture system, the atomization nozzle directly affects the effect of the aerosol culture. At present, the ultrasonic atomization at home and abroad is through the ultrasonic vibration of the ceramic thickness direction (or through the vibration of the ceramic thickness direction to drive the atomization nozzle. ) to atomize nutrient solution, there are disadvantages such as high driving circuit voltage, extremely complex circuit, serious system heating, low nozzle working efficiency, low safety, poor reliability, and easy leakage of droplets.

Abstract

The invention relates to aerial fog cultivation, in particular to an intelligent intermediate-frequency ultrasonic atomizing cultivation machine which comprises intermediate-frequency ultrasonic atomizers, temperature and humidity sensors, a control cabinet with an MCU (microprogrammed control unit) and relays, an atomization chamber, an axial-flow-type fan, a fog delivery pipeline, a nutrient solution backflow pipeline and a cultivation box. The intelligent intermediate-frequency ultrasonic atomizing cultivation machine is characterized in that temperature and humidity of a root domain environment are collected by the temperature and humidity sensors, and atomizing quantity and atomizing time of a nozzle and rotating speed and ventilation time of the fan are controlled by the MCU, so that the temperature and the humidity of the root domain environment are controlled to enable plants to be constantly in an optimal environment, and intelligent control is realized; the intelligent intermediate-frequency ultrasonic atomizing cultivation machine adopts the intermediate-frequency ultrasonic atomizers which are simple in circuit structure, low in driving voltage, large in atomizing quantity and high in working efficiency; the fog delivery pipeline and the nutrition solution backflow pipeline guarantee a nutrition solution to be recycled, so that fog utilization rate is enabled to be high, and energy resources are saved.

Description

technical field [0001] The invention relates to aerosol cultivation, in particular to an intelligent medium-frequency ultrasonic atomization cultivation device. Background technique [0002] Aerosol cultivation is the most water-saving cultivation mode. The control of insect pests can be reduced by more than 75%. The soil can be disinfected without methyl bromide, and the pollution to the environment can be effectively controlled. The nutrient solution of aerosol cultivation is in a tight lock The supply of nutrients and water is completed in the type circulation system, which can achieve zero efflux and achieve the effect of sustainable and non-polluting environment; the roots are completely suspended in the air for cultivation, without the need for traditional soil as the medium of cultivation, and there is no worry about soil erosion ; At present, it is the most potential and promising technology in horticultural production and research. It is unmatched by any previous cu...
