Description

Technical Field

[0001] The utility model relates to the technical field of air quality detection equipment, in particular to an atmospheric particulate matter monitoring device. Background Art

[0002] An atmospheric particulate matter monitoring device is a device used to detect and analyze the concentration of particulate matter in the air. These particulate matter usually include dust, smoke, pollen, bacteria, viruses and other solid or liquid particles. The presence of these particulate matter has a significant impact on air quality. Therefore, atmospheric particulate matter monitoring devices play a vital role in environmental protection and public health. By real-time monitoring and analysis of the concentration of particulate matter in the air, these devices can provide detailed data on air quality, helping relevant departments to take effective measures to improve air quality and reduce the harm of particulate matter to human health and the environment.

[0003] For example, the particulate matter monitoring device described in patent publication number CN221528340 U describes a solution comprising a main unit and a particulate matter detection module housed within the main unit, wherein the main unit is connectable to a first heater, the first heater being configured to heat the gas sample before it enters the particulate matter detection module. The particulate matter detection module includes a main unit that forms or receives a flow channel through which the gas sample flows, and a particulate matter detection device that performs particulate matter detection on the gas sample passing through the flow channel. The particulate matter detection module also includes a second heater located within the main unit and disposed on the main unit of the particulate matter detection module to heat at least a portion of the main unit of the particulate matter detection module. The second heater is a surface-mount resistor heater, and the main unit is made of metal.

[0004] In the above case, after the atmosphere is detected and the relevant measurements are completed, the particulate matter in the atmosphere will still be discharged into the external air during the gas discharge process, which may affect the air quality. In addition, there is a certain inconvenience in adjusting the height of the air intake during the use of the equipment, which makes it difficult for the operator to flexibly adjust the working state of the equipment according to actual needs. At the same time, the mobility of the equipment itself is poor, which to a certain extent limits its application flexibility in different occasions and brings additional inconvenience to the user.
