Description

Technical Field

[0002] The fire detector testing device is a key device for ensuring fire safety. It can accurately test the performance of various smoke, temperature and other fire detectors. By simulating the smoke concentration and temperature changes in a fire scene, the device can quickly detect whether the detector can respond in a timely manner and accurately alarm. The testing process is simple to operate and can perform batch testing on multiple detectors at the same time, greatly improving the detection efficiency. Whether it is a shopping mall, office building, or factory, the device can ensure that the fire detector is always in the best working condition, building a solid line of defense for fire early warning and protecting people's lives and property safety. However, there are still certain problems when using the existing fire detector testing device:

[0003] For example, a detection device for a fire facility detector with application number 202410441472.4, its technical solution is: it includes a detection device body, the top of the detection device body is connected to a detection cover with a top opening, the interior of the detection cover is provided with a sealing cover, the interior of the detection device body is provided with a smoke generating part, a smoke exhaust channel and a smoke inlet channel, the smoke inlet channel is connected between the smoke generating part and the detection cover, one end of the smoke exhaust channel is connected to the bottom of the sealing cover, the other end of the smoke exhaust channel is connected to a filter block, and a connecting pipe is provided between the smoke exhaust channel and the smoke inlet channel. The detection device body can be directly extended to the lower side of the smoke sensor through the rod body. However, when the detection device of the existing fire facility detector detects a fire detector higher in the house, the traditional detection device lacks an effective support structure, and it is difficult to stably deliver the detection equipment to the corresponding height. After the detection is completed, the residual smoke in the detection space cannot be effectively blown away. The residual smoke will interfere with the accuracy of subsequent detection results and affect the normal detection work of the next fire detector.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the emergence of this case.

[0005] In response to the above problems, an innovative design is carried out based on the original fire detector detection device. Utility Model Content
