Remote autonomous air constant-flow sampling device

Abstract

The invention discloses a remote autonomous air constant-flow sampling device, which relates to the technical field of indoor air quality detection. The remote autonomous air constant-flow sampling device comprises an air constant-flow sampler main machine and a foldable telescopic bracket, wherein the air constant-flow sampler main machine comprises an air inlet, a first tee joint, a second tee joint, a first electromagnetic valve, a second electromagnetic valve, a third electromagnetic valve, a fourth electromagnetic valve, a first rapid interface, a second rapid interface, a third rapid interface, a fourth rapid interface, a connecting hose, an adsorption tube fixing bracket, an activated carbon adsorption tube, a Tenax-TA adsorption tube, a micro orifice plate flowmeter, a sampling pump and the like. According to the remote autonomous air constant-flow sampling device disclosed in the invention, overall mailing and startup automatic operation of equipment can be carried out, the operation is simple, the operation state of the equipment can be transmitted to an equipment service platform in real time through a built-in GPRS communication module, the operation of a detected userand the real-time tracking and recording of a detection unit for a detection process are facilitated, and the long-distance running of a tester is avoided.

Description

technical field [0001] The invention relates to the technical field of indoor air quality detection, in particular to a remote and autonomous air constant flow sampling device. Background technique [0002] With the deteriorating environment, people are more and more concerned about air quality, but what hurts us is not only the bad outdoor air, but also the indoor places where we live and work. With the continuous improvement of people's living standards, the problem of indoor air pollution caused by decoration and other reasons is becoming more and more serious. The quality of indoor air quality is directly related to human health, so the detection of indoor air quality is highly valued. Most of the current sampling and testing devices require on-site testing by professionals, and the tested samples need to be brought back to the laboratory for analysis and determination, and there are few testing platforms and institutions with relevant qualifications. On-site testing is ...

Problems solved by technology

Most of the current sampling and testing devices require on-site testing by professionals, and the tested samples need to be brought back to the laboratory for analysis and determination, and there are few testing platforms and institutions with relevant qualifications. On-site testing is faced with long distances, personnel occupation, and high costs High, time-consuming and labor-intensive problems require a sampling device that is convenient for mailing. After the user receives the device, the device can be turned on and the device can run autonomously.
