Description

Technical Field

[0001] This utility model belongs to the field of industrial security equipment housing technology, specifically relating to a fire detector housing that combines heat dissipation and waterproofing functions, and features high protection, heat dissipation efficiency, and sensor collaborative operation capability. Background Technology

[0002] Fire detectors are the "sensory organs" of a system, monitoring the environment for fires. Once a fire is detected, they convert characteristic physical quantities of the fire, such as temperature, smoke, gases, and radiant light intensity, into electrical signals and immediately send an alarm signal to the fire alarm controller. Fire detectors are devices in automatic fire alarm systems that detect fires by investigating the scene.

[0003] Commercially available fire detectors typically consist of an upper housing and a lower housing that fit together, forming a cavity between them. This cavity houses the sensor, circuit board, and battery, and ventilation holes are provided on either the upper or lower housing. This structure has the following drawbacks:

[0004] 1. The cavity only has a single sensor mounting position, which cannot support the collaborative work of multiple sensors;

[0005] 2. The ventilation holes are mostly simple hollows or straight holes, which cannot balance the needs of heat dissipation and dust / waterproofing;

[0006] 3. The gaps in the casing installation were not treated, which may allow water or dust to enter.

[0007] 4. The casing is mostly made of traditional plastic or thin metal, which is prone to deformation or corrosion in high temperature, high humidity and corrosive environments, making it difficult to adapt to harsh environments such as petrochemical and power industries. Utility Model Content
