Rapid nondestructive testing device and nondestructive testing method for formaldehyde emission

The invention discloses a rapid nondestructive testing device and a nondestructive testing method for formaldehyde emission, belongs to the technical field of formaldehyde detection, and aims to solve the problems that after the formaldehyde content in air reaches a certain amount, formaldehyde in furniture is not released any more, air circulation is needed, detection is troublesome, and the internal sealing performance is difficult to guarantee. In addition, the content of the formaldehyde needs to be measured after the formaldehyde is sampled, and the formaldehyde is inconvenient to collect. Teeth on a bevel gear are meshed with tooth grooves in the two sides of the interior of an arc-shaped ring in a reciprocating mode, finally, the arc-shaped ring does up-down reciprocating motion, and when the arc-shaped ring does up-down reciprocating motion, a piston is driven by a movable rod to do up-down motion in a barrel; when the piston moves up and down in the barrel, air between the first shell and the to-be-detected object is conveyed into the collecting funnel, formaldehyde in the air is dissolved into distilled water when entering the collecting funnel, the formaldehyde is rapidly collected, the detected object can be prevented from being damaged, and operation is easy.
