Description

Technical Field

[0001] The utility model relates to the technical field of fire detectors, in particular to a fire detector with a constant temperature alarm function. Background Art

[0002] A fire detector is a device used to monitor signs of fire, aiming to detect fire early and take appropriate measures as soon as possible to reduce losses. Common fire detectors include smoke detectors, heat detectors and flame detectors. A constant temperature alarm fire detector is a device used to detect fires. It determines whether a fire has occurred by monitoring changes in ambient temperature. When the ambient temperature reaches the set value, the detector will send out an alarm signal to remind relevant personnel to take measures. This type of fire detector is suitable for various occasions, such as shopping malls, hospitals, schools and other crowded places. There are at least the following disadvantages in the use of existing fire detectors: 1. Existing fire detectors are equipped with hollow mesh covers to protect internal components, but during transportation, the hollow mesh covers will cause dust and debris to enter the detector through the gaps, thereby causing damage to the sensing components and causing losses; 2. During the installation process, the existing fire detectors have a single installation method and cannot adapt to different installation requirements. Therefore, we have launched a fire detector with a constant temperature alarm function. Utility Model Content
