Title: AUTO-SENSING OXYGEN SUPPLY PILLOW
Abstract:
An auto-sensing oxygen supply pillow (1000), comprising a main body (1010), a power supply module (1020), a controller (1030), an air valve (1040), a first air pipe (1050), an oxygen generator (1060), a second air pipe (1070), a pressure sensor (1080), a pressure detector (1090), and an oxygen concentration analyzer (1120). The power supply module (1020) is electrically connected to the controller (1030). The controller (1030) is electrically connected to the air valve (1040). The air valve (1040) has one end connected to the oxygen generator (1060) via the first air pipe (1050), and another end connected to the second air pipe (1070); another end of the second air pipe (1070) extends out of the main body (1010). The controller (1030) is further electrically connected to the pressure sensor (1080). The pressure sensor (1080) is electrically connected to the pressure detector (1090). The controller (1030) is further electrically connected to the oxygen concentration analyzer (1120). By providing the controller (1030), and employing the controller (1030) to control, according to the oxygen concentration level, the size of an opening of the air valve (1040) to control the concentration of an oxygen gas generated in the oxygen generator (1060), the auto-sensing oxygen supply pillow (1000) of the present invention controls the oxygen concentration in a region around the pillow, and provides a safe and convenient oxygen supply manner.
