Abstract

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.

Example Embodiment

[0055] In order to further and better explain the above examples, the present invention also provides an embodiment, a nondestructive testing method for a rapid nondestructive testing device for formaldehyde emission, comprising the following steps:
[0056] Step 1: Clean up the furniture or the floor to be tested, place the entire device on the surface of the furniture or the floor, make the first sealing ring 232 and the second sealing ring 234 contact with the furniture and the bottom plate, retract the telescopic cylinder 212 to make the second The bevel gear 213 meshes with the first bevel gear 211, and then when the double-headed motor 121 rotates, the connecting rod 216 rotates, and the spur gear 2315 meshes with the rack 2314 so that the sealing slider 2313 slides inside the arc cavity 2311. At this time, the arc negative pressure inside the cavity 2311, and extract the air between the first sealing ring 232, the second sealing ring 234 and the object to be detected to keep it sealed;
[0057] Step 2: When the double-headed motor 121 rotates, the piston 133 reciprocates up and down inside the barrel 131 through the drive assembly 12, and when the piston 133 moves upward, the air inlet assembly 134 extracts the space between the first housing 14 and the object to be detected. When the piston 133 moves downward, the air is discharged into the collection funnel 151 through the exhaust assembly 135 and the first connecting pipe 136;
