Description

Technical Field

[0001] The utility model relates to the technical field of building environment detection, in particular to a building environment particle size detection device. Background Art

[0002] "Architecture" is a broad concept, usually referring to objects with fixed spatial forms and structural forms created by humans to meet various needs of life, production or religion. These objects can include residences, office buildings, factories, bridges, roads, temples, palaces, monuments, etc. The built environment refers to the surrounding environment of the building. In order to ensure human health and environmental quality, it is necessary to measure and analyze the concentration of particulate matter in the built environment. These particulate matter may include dust, pollen, bacteria, viruses, etc. They are suspended in the air and require the use of particle size detection devices.

[0003] Common building environment particle size detection devices usually include an air intake system, a particle sampler, a particle analyzer, and a data processing system. The air intake system inhales air, the particle sampler collects particles in the air, the particle analyzer is responsible for analyzing the characteristics of the collected particles, and the data processing system is used to process and analyze the data obtained from the particle analyzer. This is a common building environment particle size detection device structure and usage. Traditional building environment particle size detection devices need to fix the device at a certain location in the building environment for detection, but after the detection is completed, the position needs to be changed. However, since the instrument is usually fixed with screws, it is necessary to use tools to disassemble and assemble the screws during disassembly, which is not convenient for operation. Some building environment particle size detection devices fix the device by using an external frame and a card plate, which is convenient for disassembly and assembly. However, this method requires the installation and movement of the entire device at different heights to conduct a comprehensive detection of the building environment, and the external frame and the device will increase the overall weight of the device, making it difficult to adjust the position, etc. Therefore, a building environment particle size detection device is proposed.
