[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines and equipment, including factories, theaters, hotels, shops, schools, hospitals and residences, etc., to meet people's needs for production, residence, study and public activities. Construction engineering safety fire protection refers to a series of fire protection measures taken during the construction of construction projects to ensure fire prevention and emergency evacuation at the construction site.

[0003] Existing fire warning equipment usually has a smoke detector. When there are objects burning nearby, the smoke generated by the burning will enter the maze in the smoke detector from the entrance of the smoke detector. The smoke entering the maze will be detected by the sensor installed inside the smoke detector, so that the alarm device in the smoke detector will sound an alarm. However, at the construction site of the construction project, a large amount of dust and powder will be generated during the construction. This dust and powder can easily enter the interior of the smoke detector through the entrance of the smoke detector, which can easily cause damage to its internal components and cause detection failure. Therefore, it needs to be improved. Utility Model Content
