Semi-permanent water curtain absorption type formaldehyde detection box

Abstract

The invention discloses a semi-permanent water curtain absorption type formaldehyde detection box, and belongs to the field of formaldehyde detection. The semi-permanent water curtain absorption type formaldehyde detection box comprises a box body, wherein multiple layers of liquid curtain plates, a liquid gathering pressing plate and a liquid pressing floating plate are sequentially arranged in the box body from top to bottom. By arranging the multiple layers of liquid curtain plates, a detection reagent is in full contact with air in a continuously dispersed and dripped water curtain state to quickly absorb formaldehyde in the air, and the detection reagent in the box body is subjected to gravity pressurization through gathering and intermittent falling movement of the detection reagent by the water gathering pressing plate, so that the detection reagent is re-risen through the re-rising pipe to realize a re-dripping process, Therefore, in the formaldehyde detection process, the detection reagent is automatically subjected to semi-permanent water curtain type dripping movement, continuous and sufficient contact between the detection reagent and air is achieved, formaldehyde is effectively absorbed, and the accuracy of the detection result is greatly improved.

Description

technical field [0001] The invention relates to the field of formaldehyde detection, in particular to a semi-permanent water curtain absorption type formaldehyde detection box. Background technique [0002] The formaldehyde detection box is a test tool that can detect formaldehyde content. It is used for consumers to quickly and semi-quantitatively experience the formaldehyde that may be encountered in the living environment, and can determine the degree of formaldehyde pollution. It is generally composed of absorption box, diluent, color developer, absorbent and color comparison card. The diluent, color developer and absorbent are packaged separately before use. [0003] The general method of using the formaldehyde detection box is: before the test, close the doors and windows of the room to be tested for 1 hour, mix the diluent and absorbent, and pour them all into the absorption box; place the absorption box indoors at the part to be tested or 80 to Expose for 30 minutes...

AI Technical Summary

Problems solved by technology

[0004] When the existing formaldehyde detection box is used for detection, due to the poor indoor air circulation, the detection reagent is placed in the absorption box and has poor contact with the air, which makes it difficult for the detection reagent to fully and effectively absorb the formaldehyde in the room, resulting in the detection result Big error, poor accuracy
