It also enables automatic operation control of related equipment based on ozone concentration.

[0003] The SKD-610 series duct-type ozone transmitter can be used in various intelligent buildings and HVAC systems, such as airports, train stations, subway stations, pharmaceutical factories, museums, intelligent buildings, and stadiums. The product uses a high-performance processor, offers multiple output signals, and can accurately detect ozone content. It adopts an imported ozone sensor, which has the advantages of stable signal, high sensitivity, and high accuracy. The duct-mounted version is equipped with a flow-guiding PC probe, which can meet the high-precision and high-stability measurement requirements of duct environments.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following deficiencies: In existing technologies, when detecting ozone in pipelines, dust and other impurities may exist inside the pipeline. Existing equipment has poor dustproof performance, easily allowing dust to enter the transmitter through the probe, affecting the transmitter's detection performance and lifespan. This application addresses this problem by incorporating components such as a fixing ring, spring, dust filter, and limiting ring. Through the connection of magnetic ring one and magnetic ring two, the dust filter is connected to the top ring. The connection between the threaded pipe and the connecting pipe allows the dust filter to be installed inside the probe, effectively preventing dust particles from entering the transmitter, ensuring its detection performance, and improving its lifespan. Utility Model Content

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model comprises components such as a fixing ring, a spring, a top ring, a magnetic ring I, a magnetic ring II, a dust filter, and a limiting ring. When the device is needed, the dust filter is connected to the top ring via magnetic ring I and magnetic ring II. Then, a threaded tube is fitted onto the surface of the dust filter, and the threaded tube is aligned with the connecting tube. Rotating the threaded tube allows it to connect with the connecting tube. During the connection process, the dust filter is blocked by the limiting ring. At this time, the dust filter is pressed tightly by the connection between the fixing ring, the spring, and the top ring, thus achieving the installation of the dust filter. By setting a dust filter inside the probe, dust particles can be effectively prevented from entering the transmitter, thereby ensuring the transmitter's detection performance and improving its service life.

The through-hole is located on the side of the probe tube, and the two through-holes are interconnected. During installation, airflow is ensured to pass through the through-hole, facilitating airflow into the equipment housing. The lower housing is fixed to the pipe surface using connectors and wood screws, with heat insulation material, specifically rock wool, placed between them. Rock wool possesses excellent heat insulation properties, effectively blocking heat transfer from the pipe to the transmitter, ensuring the transmitter operates in a stable temperature environment. Simultaneously, rock wool exhibits outstanding sound absorption and noise reduction properties, effectively absorbing and blocking sound propagation, reducing noise generated by fluid flow within the pipe and interference from external environmental noise on the transmitter's operation, creating a relatively quiet working environment for the transmitter, and contributing to improved measurement accuracy and stability.
