This creation is a sleep micro-environment control device, including a cover body, an air intake device, and an air extraction device. The cover body has a micro-environment space that can cover the upper and side positions of the human head; and the air intake device It has an air intake pipe, a filtering device, and an air conditioning device. One end of the air intake pipe is connected to the cover; the filter device is connected to the air intake pipe; and the air conditioning device is connected to the other end of the air intake pipe, and the external air is filtered The device and the air intake pipe are introduced into the micro-environment space, and the micro-environment space is formed with positive pressure; by this way, the creation can provide a micro-environment control to improve sleep quality and have the effect of eliminating germs.本創作係一種睡眠微環境控制裝置,包括一罩體、一進氣裝置、一抽氣裝置,該罩體具一微環境空間可罩住人體頭部上方及側方位置;又該進氣裝置具一進氣管、一過濾裝置、一空調裝置,該進氣管一端連接罩體;又該過濾裝置連接進氣管;又該空調裝置與進氣管另一端連接,並使外部氣體經由過濾裝置及進氣管導入微環境空間內,且使該微環境空間形成正壓;藉此本創作可提供微小環境控制提升睡眠品質並具消滅病菌功效。
