With its rope reel, rope take-up wheel, torsion spring, pull rope, moving bar, scraper, pulley, side locking block, slide rail, and pull plate, the user only needs to pull the pull plate to move the moving bar along the slide rail when cleaning the transparent window. This allows the scraper to effectively remove dust or moisture adhering to the transparent window, significantly improving visibility. The pull rope is pulled out along with the moving bar and drives the rope take-up wheel to rotate, causing the torsion spring to store energy. When the pull plate is released, the torsion spring releases energy, causing the rope take-up wheel to reverse and automatically retract the pull rope. This also allows the moving bar and scraper to quickly return to their original positions. This process is simple and quick to operate, does not affect escape, and has a reliable structure and good repeatability, significantly enhancing the practicality and safety of the breathing mask in complex fire environments.

[0017] 2. With the inclusion of searchlights, indicator lights, and a battery box, the searchlights provide stable illumination in dense smoke environments, helping users identify escape routes and their surroundings. The indicator lights, with their high brightness, significantly enhance visibility in smoke, making it easier for rescuers to quickly locate users. This setup greatly improves safety and escape efficiency during fire rescue operations. Attached Figure Description

A moving strip 25 is provided below the stop block 14. A scraper block 18 is provided on the moving strip 25. A pulley 17 is provided at both ends of the moving strip 25. A slot 16 is provided on the pulley 17. A slide rail 8 is provided on both sides of the transparent window 12. A side locking block 15 is provided on both sides of the slide rail 8.

[0027] In this embodiment, the fire emergency breathing mask is a personal protective equipment specially designed to help people breathe safely in emergency situations such as fires. It is usually made of flame-retardant materials and can effectively filter smoke, toxic gases and high-temperature particles, providing the wearer with relatively clean air and extending escape time. The method of using the fire emergency breathing mask is as follows: First, put the headgear 1 on the head and fix it with the Velcro 9 at the bottom to ensure a seal. Then, the main filter 11 begins to provide the main filtration function. The fixing strap 5 on it can further adjust and fix the breathing mask. The side filter ports 10 on both sides of the headgear assist in air circulation and filtration to ensure smooth breathing. At the same time, the user can observe the surrounding environment through the transparent window 12 on the front of the headgear so as to move safely in an emergency.
