According to the request of adopting advanced technology, the main designing has such contents as below:⑴ Designing the two-fluid nozzle that is based on the theory of air-atomize spraying.⑵ Designing and choosing the type of the axial fan that is used to supply assisted airflow to waft droplets that comes from nozzle.⑶ Designing the swaying outfit that can rotate the spray assembly at a speed and inside a angle in order to satisfy the spray request of different crops, different planting states and improve the uniformity of distribution, the deposition of droplet. Here, we select TYV type reduction gear motor to adjust the swaying speed and use course switch to adjust the swaying angle.⑷ Designing the lift outfit that can adjust the height of the spray assembly to satisfy the request of the crops of different tallness, different spraying range. Here, we select cylinder as the main component that can be used as kickstand and controlled easily.⑸ Designing the switch of the power supply that is put out of the greenhouse in order to prevent worker from poisoning. After the mist sprayer being made, the experiment is made to test the function of the greenhouse mist sprayer fully.

根据采用先进施药技术的要求，本研究的设计内容主要有：⑴采用气液两相流喷雾技术，基于气力雾化原理，设计双流体喷头；⑵采用辅助气流输送雾滴，气流源为风机，对风机进行设计、选型；⑶为满足不同作物、不同栽培情况及提高雾滴分布均匀性、沉积性的施药要求，设计能带动喷射部件在一定角度内、以一定转速的旋转摇摆机构，本研究选用调速电机调节其摇摆速度，并利用反向行程开关调节其摇摆角度；⑷为满足不同高度作物、不同射程的施药要求，设计能调节喷射部件高度的升降机构，这里选用气缸为主要构件，既可以起到整机支架的作用，又可方便进行升降、固定控制；⑸设计行程开关的控制电路以及整机的控制系统。
