Intelligent indoor oxygenating device for building

The invention relates to the technical field of oxygen supplementation devices, and discloses a building intelligent indoor oxygen supplementation device which comprises a box body, a mounting chamber is formed in the box body, a hanging water supplementation component is arranged in the mounting chamber, an automatic water supplementation component is arranged on the top wall of the mounting chamber, and a control panel is arranged on the front face of the box body. Oxygen exhaust holes are formed in the left side surface and the right side surface of the box body; after water in the humidification bottle is used, the weight is reduced, a tension spring can contract to drive a sleeve to move upwards, a sliding plate can be driven to move upwards, a magnetic block continuously attracts the sliding plate, the sliding plate abuts against and is attracted to the bottom side of the magnetic block, then a pressure sensor is extruded to transmit signals to a control panel, and an electromagnetic valve is opened thr
