Document Type and Number:
WIPO Patent Application WO/2019/227829
Kind Code:
A1
Abstract:
A protective device for isolation, comprising a machine frame (1), a purification unit, a fan (2) provided inside the machine frame (1) and used to form a positive and negative pressure difference therein, and a first air outlet duct (3) for forming an isolation air curtain. An air inlet of the fan (2) is used to draw in external air. The machine frame (1) is internally provided with the purification unit, and the purification unit communicates with the air inlet of the fan (2). An air outlet of the fan (2) communicates with the first air outlet duct (3). The first air outlet duct (3) is provided at the top of the machine frame (1), and the first air outlet duct (3) is parallel to a long side of the machine frame (1). The first air outlet duct (3) is internally provided with at least one guiding strip (4) for tilting the isolation air curtain towards the direction of an infectious source, and an angle between the guiding strip (4) and the normal direction of the first air outlet duct (3) is 15°-25°. The protective device isolates an infectious source from uninfected people, so as to protect the health of the uninfected people. The entire device has a simple structure, and provides effective and reliable isolation.
