Formaldehyde chemical detection system

The invention discloses a formaldehyde chemical detection system which comprises a base supporting mechanism, a center shaking mechanism, an elastic swinging mechanism, a side cover transmission mechanism and a formaldehyde detection mechanism, the base supporting mechanism is a main body supporting mechanism, is formed by welding steel and can bear large gravity and shaking, the center shaking mechanism is of a middle layer structure and can shake an ascending mechanism at low frequency, sufficient mixing of gas is guaranteed, the elastic swinging mechanism drives a two-way lead screw and a connecting rod set through a motor so as to drive a gas storage tank to swing, and the side cover transmission mechanism provides power for the ascending mechanism so as to drive the ascending mechanism to swing; power is transmitted to each working area through transmission parts such as a gear belt, the formaldehyde detection mechanism is a core detection mechanism, gas input can be detected by a chip, and a result is o
