The utility model relates to the technical field of spectral analysis, in particular to an inflation and deflation device used in the field of deep sea LIBS detection. The device comprises a pressure-resistant cabin, an air bag, a piston and an exhaust mechanism, the air bag is arranged in the pressure-resistant cabin, and the exhaust mechanism is arranged at one end of the pressure-resistant cabin and connected with the air bag; the piston is arranged at the other end of the pressure-resistant cabin and is in sliding connection with the inner wall of the pressure-resistant cabin; a water inlet is formed in the other end of the pressure-resistant cabin, so that seawater gives water pressure of the current working depth to the air bag through the piston. When the device works in a deep sea high-pressure environment, only low-pressure gas needs to be inflated into the air bag, high-pressure seawater entering from the water inlet pushes the piston, the gas in the air bag reaches an extremely high pressure level,
