Atomic absorption spectrophotometer with air suction structure

The utility model discloses an atomic absorption spectrophotometer with an air suction structure, which comprises a spectrophotometer body, the left side wall of the spectrophotometer body is provided with a flue gas purifier, the upper end face of the flue gas purifier is provided with a support plate, the inside of the support plate is in sliding connection with a moving rod, and the moving rod is provided with an air suction structure. When the atomic absorption spectrophotometer is used for detecting trace elements, a fan is started, a suction hood absorbs waste gas, the waste gas is introduced into a flue gas purifier through a ventilation pipe to be purified, and when the height of the suction hood needs to be adjusted, a motor is started, so that a moving rod can drive a top plate and the suction hood to move; the effect that the height of the suction hood is convenient to adjust is achieved, smoke is convenient to absorb, in the using process, when the suction hood blocks the visual field of workers,
