Description

Technical Field

[0001] This utility model relates to the field of fire detection technology, specifically a pyrolysis particle detector with adjustable suction direction. Background Technology

[0002] With the increasing prominence of environmental pollution and public health issues, the detection of particulate matter concentrations, especially harmful gases and organic particles, in the air has become particularly important. Pyrolysis particle detectors, as a highly efficient air pollution monitoring device, can detect the composition and concentration of particulate matter in the air in real time, which is of great significance for environmental monitoring and safety early warning.

[0003] In response, Chinese patent application number CN218100394U discloses a pyrolysis particle detector, including a housing and a base. Mounting tubes are fixedly installed at both ends of the top of the housing. Two sets of mounting tubes are rotatably mounted with guide fans inside. Ventilation holes are provided at both ends of the housing. A detector monitoring module and a temperature monitoring module are fixedly installed inside the housing. The two sets of guide fans, connected to the mounting tubes via a connecting shaft and a connecting shaft hole, rotate in opposite directions. Therefore, this device is more convenient to install directly into the power distribution cabinet, avoiding the need for additional fans. Furthermore, depending on the cable arrangement in the power distribution cabinet, the two sets of guide fans can rotate in the direction of the cable arrangement, more accurately capturing pyrolysis particles. Compared to traditional methods, this device is easier and faster to install, and the direction of the intake air can be adjusted according to actual conditions.

[0004] This fire detection device has significant limitations when adjusting the airflow fan, and it has blind spots when detecting in different environments or at different angles, affecting the comprehensiveness of the data. It also tends to suck in larger particles in the air, which may damage the internal modules of the device.

[0005] To address this issue, we propose a pyrolysis particle detector with adjustable intake direction. Utility Model Content
