Formaldehyde detector

Abstract

The invention discloses a formaldehyde detector. The formaldehyde detector comprises a fixed plate and a first sliding plate located on the fixed plate, the first sliding plate can move up and down, aright end of the first sliding plate is fixedly provided with a sealed box, a work box is fixedly arranged on the sealed box, a working chamber is arranged in the work box, an air pump is fixedly arranged in the working chamber, an admission pipe is fixedly arranged on the air pump, and the admission pipe penetrates to an external side of the work box through the working chamber. The formaldehydedetector can monitor concentration of formaldehyde in the air in sealed space more simply, according to difference of concentration of the formaldehyde, the formaldehyde detector converts the formaldehyde of different concentration into light of different intensity, a light receptor converts the light into current and provides the current to a motor, by observation on difference of liquid level height, concentration of the formaldehyde in the air can be simply and clearly detected. The formaldehyde detector also can change altitude of a detection mechanism to detect concentration of the formaldehyde in the air at different altitudes in the same space.

Description

technical field [0001] The invention relates to the detection field, in particular to a formaldehyde detector. Background technique [0002] At present, after the decoration of buildings, there will be more formaldehyde residues. Many inspection departments need to detect the content of formaldehyde to ensure people's safety. However, the detection accuracy of traditional formaldehyde detectors is poor, and the degree of intelligence is low. The performance is poor, the detection is cumbersome, and the formaldehyde content in the air at different heights in the same space cannot be detected. Therefore, a formaldehyde detector is urgently needed to solve the above problems. In view of the above shortcomings, the present invention has been improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a formaldehyde detector, which overcomes the above-mentioned problems. [0004] The present invention is achieved throu...

[0002] At present, after the decoration of buildings, there will be more formaldehyde residues. Many inspection departments need to detect the content of formaldehyde to ensure people's safety. However, the detection accuracy of traditional formaldehyde detectors is poor, and the degree of intelligence is low. Poor performance, relatively cumbersome detection, and can not detect the formaldehyde content in the air at different heights in the same space, so a formaldehyde detector is urgently needed to solve the above problems, and the present invention improves on the above shortcomings
