Disclosed is an airbag type lifting device of plant cultivation cabinet, which particularly relates to a lifting device applicable to plant cultivation and is used for adjusting the distance between plants and an artificial light source. The device mainly consists of a box body, an airbag, an inflating device and a lifting device. The box body has a receiving space in which a water tank is placed at the lower part while the artificial light source is arranged at the upper part for cultivating plants. Additionally, the lifting device is installed under the water tank with an airbag arranged inside, therefore, the inflating device can be used to inject air into the airbag, thereby raising the height of the water tank in order to bring the plants closer to the artificial light source. The lifting device can also be installed above the artificial light source and the airbag can be inflated by means of the inflating device to press a moving plate to make the artificial light source moved downwardly, thereby bringing the artificial light source closer to the plants. The disclosed features a better light irradiation density effect to promote the plants to grow and the lifting device can be matched up with a height sensor or an image photographing to adjust the lifting height.本發明係有關於一種植物栽培櫃之氣囊式升降裝置,特別是指一種用於植物栽培的升降裝置,以調整植物與人工光源的距離,其主要係由箱體、氣囊、充氣裝置及升降裝置所組成,該箱體具有容置空間,下方放置水槽,上方則設置有人工光源,供栽培植物,並於水槽下方裝設一升降裝置,其內部放置有氣囊,可利用充氣裝置將氣體注入氣囊,而能提昇水槽高度,使植物更接近人工光源,或將升降裝置設置在人工光源上方,同樣可藉由充氣裝置將氣囊充氣,使其擠壓活動板,促使人工光源向下移動,而能更靠近植物,亦具有較佳之光密度照射效果,以促進植物的生長,且該升降裝置能配合高度感應器或影像拍攝來調整升降的高度。11‧‧‧箱體112‧‧‧水槽113‧‧‧人工光源21‧‧‧氣囊22‧‧‧升降裝置221‧‧‧套合座2211‧‧‧容槽222‧‧‧活動板23‧‧‧充氣裝置3‧‧‧植物4‧‧‧控制器41‧‧‧高度感應器
