Detailed Description

Example 1

In order to solve the above-mentioned technology, the utility model provides a formaldehyde detection device, as shown in fig. 1-4, comprising an external packing box 1, a detection box 2 placed inside the

external packing box

1, and 3 containers for holding reagents and located in the detection box 2, in this embodiment, the external packing box 1 and the detection box 2 are made of paper, and after the external packing box 1 and the detection box 2 are used, the paper can be thrown as recyclable garbage, so that the detection environmental protection performance is improved. The container comprises an absorption liquid containing pipe 3, a color development liquid containing pipe and a reaction round box 4, wherein the absorption liquid containing pipe 3 is a round pipe with a sealing cover, the absorption liquid containing pipe is transparent, the color development liquid containing pipe is a round pipe with a sealing cover, the absorption liquid containing pipe is black, the reaction round box 4 comprises a box body and a cover body connected with the box body in a buckling mode, a medicament is contained in the box body, and the height of the box body is higher than that of the detection box 2. The inventor chooses the transparent round tube as the absorbing liquid containing tube 3 and chooses the black round tube as the developing liquid containing tube, so that the user can clearly distinguish the two reagents, and confusion during use is avoided.
