Portable formaldehyde detection instrument

Abstract

The invention discloses a portable formaldehyde detection instrument. The instrument comprises a detection casing, wherein a detection port is mounted at the top of the detection casing; keys are embedded in the front surface of the detection casing; a display screen is mounted at the top of the front surface of the detection casing; a rolling box is mounted at the top of the display screen and located on the surface of the detection casing; a rolling rod is mounted in the rolling box; elastic pieces are mounted at the two ends of the rolling rod; and a cotton piece is rolled on the rolling rod. The instrument has the advantages that when the instrument is carried, the display screen of the instrument is covered with the cotton piece, so that a squeezing force on the surface of the displayscreen can be reduced during carrying, and abrasion of the display screen, which affects the reading of detection values, can be prevented; and protection edges are mounted on the side edges of the detection instrument, so that if the device falls during use and lands on one side, the corresponding protection edge squeezes spring columns under the stress, and the spring columns are then deformedunder the stress and generate counterforces to reduce an impact force on the instrument, which improves the safety of the instrument.

Description

technical field [0001] The invention belongs to the technical field of formaldehyde detectors, in particular to portable formaldehyde detectors. Background technique [0002] The formaldehyde detector realizes the quick and semi-quantitative detection of formaldehyde in the indoor air on site, and has the characteristics of simple structure, small size, easy to carry and use, and intuitive. It can be widely used in on-site quantitative and qualitative detection of formaldehyde in the air of living rooms, indoors, residential areas, public places, living places and factories and mines. The portable indoor air formaldehyde on-site detector is designed according to the principles of national standards. The formaldehyde detection instrument adopts the principle of high-sensitivity electrochemical sensors, combined with single-chip microcomputer technology and network communication technology to collect air samples from the detection site. The formaldehyde in the air is detected ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a portable formaldehyde detector to solve the existing portable formaldehyde detector proposed in the above-mentioned background technology. Usually, when in use, the formaldehyde detector collects air samples at the detection site, and the belt value is determined. You can directly read the value on the formaldehyde detector to know the content of formaldehyde. However, if the instrument is not carefully protected when it is carried and used, the display screen on the surface of the instrument is prone to extrusion wear, resulting in the display being crushed Or there are scratches, resulting in the problem that the detection value cannot be observed
