具体的，液体箱13中设有用于对随动杆23进行导向的第二导向套24，随动杆23滑动连接在第二导向套24中。随动杆23的上端滑 动连接有活动杆27，活动杆27上设有堵头28，堵头28与活动杆27之间设有弹性元件29，导气管11伸入液体箱13中的一端的端口处设有与堵头28相对应的出气口30。本方案中，弹性元件29为弹簧。
具体的，随动杆23上设有导向槽26，活动杆27滑动连接在导向槽26中，弹性元件29设置于随动杆23的端面与堵头28之间。优选的，出气口30呈锥孔状，出气口30上具有内圆锥面，堵头28上具有与出气口30上的内圆锥面配合的外圆锥面。
浮力体14在上下移动的过程中，具有一个触动位置。当浮力体14移动至触动位置及以下的位置时，杠杆25对应导气管11的一端被翘起，此时堵头28在杠杆25和随动杆23的传动下堵住导气管11上的出气口30，导气管30停止向液体箱13中出气。对应的，当浮力体14移动至触动位置及以上的位置时，堵头28和出气口30之间设有间隙，导气管11内的气体进入液体箱13内。
回流箱16上连接有回流管19，回流箱16与液体箱13之间通过补液管17相连。具体的，回流箱16的位置高于液体箱，补液管17上连接有第二单向阀18。回流管19用于将喷出后未被植物根系吸收的营养液导流至回流箱中，回流箱16中的营养液可以通过补液管流入液体箱13中，从而对液体箱13补充营养液。第二单向阀18的作用是防止液体倒流。
本发明中，通过空气收集装置收集自然界中的空气资源，并将其转化为压缩空气储存在储气装置中，储气装置6中压缩空气通过导气管通入液体箱中，并气体压力的作用下，液体箱中的营养液通过喷雾 管喷出，从而对植物的根系喷营养液，从而达到雾化栽培的目的。本装置不依赖电能，优选降低了电费成本的支出，提高雾化栽培的经济效益。
液位控制装置的工作原理如下：浮力体的密度小于营养液的密度，浮力体可以浮在营养液上，并可以随着营养液的液面高度发生上下移动。当营养液液面高度处于高位时，浮力体移动至较高的位置，此时浮力体的上端面与密封圈接触并将通孔堵住，液体箱内部形成一个封闭的空间，此时浮力体收到两个向上的作用力，分别为营养液对浮力体的浮力F1和液体箱内部气压对浮力体向上的气体作用力F2,其中F2的大小为液体箱内外气压差与浮力体竖直方向投影面积的乘积，此时导气管不断地向液体箱中通入一定压力的气体，营养液则在气压的作用下从喷雾管中喷出；营养液在不断喷出的过程中，营养液的液面高度不断下降，此时浮力体受到的浮力也不断减小，当液面下降到某一高度后，此时浮力F1和气体作用力F2不足以支撑浮力体维持在该高位，这时，浮力体会发生下降，浮力体在下降的那一刻，通孔将液体箱内部与外界大气连通，液体箱内部的气压下降至于外界气压相同，此时作用在浮力体上的力F2消失，浮力体会下降一定的距离，直至停留在浮力与重力平衡的位置；浮力体在下降的过程中，会达到或低于触动位置，使堵头将导气管的出气口堵住，使导气管停止向液体箱中通气；与此同时，由于液体箱内部的气压也下降到了与大气压相同的水平，营养液便不再从喷雾管中喷出，回流箱中的液体便通过补液管向液体箱中补充营养液，使营养液液面高度逐渐回升；在 回升的过程中，浮力体随着营养液液面高度逐渐上升，当浮力体上升至高于触动点的位置时，导气管重新打开，继续向液体箱中通气；当浮力体上升至刚好将通孔堵住的位置时，此时液体箱中又形成一个封闭环境，液体箱内部的气压上升，浮力体受到的气体作用力F2牢牢地将浮力体顶在上端位置，与此同时，液体箱中的营养液则重新通过喷雾管喷出。如此循环，使得液体箱中的营养液高度始终保持在一定的高度范围之间，保证营养液长时间的自动供给。
本装置可适用于海上平台、西部等风力资源丰富的地区。本发明除了可以应用在雾化栽培领域，还可以应用于蘑菇等菌类栽培、植物补水等场合。。
本发明不局限于上述最佳实施方式，任何人在本发明的启示下都可得出其他各种形式的产品，但不论在其形状或结构上作任何变化，凡是具有与本申请相同或相近似的技术方案，均落在本发明的保护范围之内。
