Description

Technical Field

[0001] This utility model relates to the field of fire detector technology, and more specifically, to a protective structure for a fire detector. Background Technology

[0002] A fire detector is a device used to detect the occurrence of a fire. It can sound an alarm when the fire is in its early stages or when the smoke concentration reaches a certain threshold, helping people to evacuate in time and take emergency measures. Fire detectors mainly work by detecting fire-related physical or chemical changes (such as smoke, temperature, gases, etc.).

[0003] Existing fire detectors are often affected by the external environment during use, such as the entry of impurities like flying insects, which can lead to contamination and damage to the sensitive components inside the detector, thereby affecting the accuracy and reliability of the detector.

[0004] Therefore, we have made improvements to this and proposed a protective structure for fire detectors. Utility Model Content

[0036] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The limiting component 4 includes a housing 401, which is fixedly installed on one side of the fixing plate 3. Springs 402 are fixedly installed at the top and bottom of the inner cavity of the housing 401. Baffles 403 are fixedly installed on opposite sides of the two springs 402, and inclined blocks 404 are fixedly installed on opposite sides of the two baffles 403. Sliding blocks 405 are fixedly installed on both sides of the baffles 403.

The fire detector body 2 can more accurately detect and identify fire-related signals such as smoke and temperature, reduce the possibility of false alarms, and improve the accuracy of fire detection. When it is necessary to clean the surface of the filter screen 9, rotating the rotating ring 1001 drives the rotating plate 1002 to rotate. Through the cooperation of the limiting block 1008 and the limiting groove 1009 of the first connecting rod 1003 and the second connecting rod 1004, the filter screen 9 is driven to rotate. The rotating disk 1005 rotates, and the inclined cleaning plate 1007 rotates with the rotating disk 1005 through the connecting block 1006, thereby cleaning the surface of the filter screen 9. This can clean the dust and flying insects adsorbed on the outside of the filter screen 9, effectively removing the flying insects adsorbed on the outside of the filter screen 9, ensuring the continuous and effective operation of the filter screen 9, and thus ensuring the stability of the fire detector body 2 during operation. When it is necessary to disassemble the conical protective cover 5, the first connecting rod 1003 and the second connecting rod 1004 can be separated. When installing, the first connecting rod 1003 and the second connecting rod 1004 can be inserted.
