PURPOSE: A suffocation prevention device for a vehicle using a carbon dioxide detector and a suffocation prevention method using the same are provided to generate oxygen by electrolyzing water generated when carbon dioxide is removed and supplying the oxygen to the inside the vehicle. CONSTITUTION: A suffocation prevention device for a vehicle using a carbon dioxide detector comprises a carbon dioxide detector(110) and an alarm signal generation unit. The carbon dioxide detector measures the concentration of carbon dioxide in a vehicle and removes the carbon dioxide. The carbon dioxide detector generate oxygen by electrolyzing water generated when the carbon dioxide is removed and discharges the generated oxygen to the inside the vehicle. The alarm signal generation unit receives the measured results from the carbon dioxide detector and outputs an alarm signal to the outside.

Abstract:
The present invention provides a solidification preventing powder extinguisher including a magnetic force part periodically rotating a magnetic body forwards and backwards using a magnetic force outside the main body, wherein the magnetic body is inserted into the main body of the powder extinguisher. The present invention rotates a magnet, which generates the magnetic force, outside the powder extinguisher after inserting the magnetic body into the powder extinguisher in order to stir extinguishing powder with the magnetic body rotated by the magnetic force of the magnet, thereby preventing the solidification of the extinguishing powder. The present invention also periodically and automatically rotates the magnetic body, thereby removing inconvenience for regularly shaking the powder extinguisher by a manager, saving the extinguishing powder which has been solidified and disposed by poor management, and minimizing damage to humans and properties by the function of the powder extinguisher in an actual fire. In addition, the present invention is capable of applying an existing powder extinguisher without modifying the shape of the powder extinguisher, and stably stores and manages the powder extinguisher using a holder, thereby improving marketability.
