The invention discloses a lifesaving schoolbag device for children. The lifesaving schoolbag device comprises a GPS (global position system), a photovoltaic cell, a storage battery, an electronic control valve, a water sensor, a controller, a carbon dioxide cylinder, an alarm speaker, schoolbag strap air bags, an air duct and schoolbag back air bags. When a child falls into water, the water sensor mounted at the schoolbag bottom detects a signal and transmits the signal to the controller, the controller sends a signal to control the electronic control valve to open, gas in the carbon dioxide cylinder is sent into the schoolbag strap air bags and the schoolbag back air bags through the air duct, meanwhile, the controller sends a signal to control the alarm speaker to make an alarm sound, the GPS can sends a positioning signal, and a parent can get the specific position of the child instantly through a receiver in a hand. Solar energy is converted by the photovoltaic cell into electric energy for a system, and the electric energy is stored in the storage battery to power the GPS, the electronic control valve, the water sensor and the controller.
