Description
Technical Field
[0001] The present invention relates to the technical field of respirators, and in particular to an anti-loss type integrated valve emergency escape respirator. Background Art
[0002] In modern society, toxic and hazardous gases, thick smoke, and hypoxia pose serious threats to life in disaster scenarios such as fires, chemical accidents, and mine collapses. Emergency respirators have become indispensable safety equipment. For example, the carbon monoxide and hydrogen cyanide produced by combustion can quickly cause coma or even death. Thick smoke obscures vision, hinders escape, and causes the inhalation of large amounts of hot particles and harmful gases, damaging the respiratory tract. At the scene of a mine accident or chemical leak, flammable, explosive, or highly corrosive gases like methane and chlorine permeate the air, making ordinary air unbreathable. Therefore, in modern society, fires, chemical accidents, mine collapses, and other disasters are frequent. In these scenarios, toxic and hazardous gases, thick smoke, and hypoxia pose serious threats to life, making emergency respirators indispensable safety equipment.
[0003] However, conventional emergency escape respirators (ERVs) suffer from two common drawbacks: First, the complex connection between the mask and the main body requires multiple steps to secure in an emergency, and the lack of stability makes them prone to loosening and falling off during strenuous exercise. Second, they lack a reliable anti-loss design. When idle, the device is often placed haphazardly, making it difficult to quickly locate in an emergency or accidentally lost during transport due to an inappropriate binding structure. Furthermore, the valve components of conventional respirators are often distributed, occupying a large space and easily affecting sealing performance, resulting in a low level of integration. Therefore, a novel emergency escape respirator with an anti-loss integrated valve is proposed to address these issues. Summary of the Invention
[0004] In order to make up for the above shortcomings, the present invention provides an anti-loss integrated valve emergency escape respirator, which aims to improve the problems of lack of anti-loss design and slow wearing and fixing in the existing technology.

[0012] Working principle: When facing sudden danger and needing to use the emergency escape respirator quickly, the user should quickly and steadily place the breathing mask 1 in front of the face to ensure that the mask fits the facial contour. Then, slide the card shaft 3 accurately into the docking column 4. This step lays the foundation for subsequent fixation. Then, rotate the rotating shaft 11. This operation will drive the control spiral column 10 to start rotating in the card column 1 6 and the card column 2 7. The card column 1 6 and the card column 2 7 are designed with threaded connection. This unique structural feature allows the two to move in opposite directions along a specific direction when the spiral column 10 rotates. At the same time, the slide groove 8 opened on the top of the card column 1 6 and the card column 2 7 will maintain stable movement under the constraint of the beam slide 5. Trajectory, in this series of linkages, the slots 9 opened by the card column 1 6 and the card column 2 7 gradually approach each other, and finally tightly clamp the card shaft 3 to achieve a firm clamping connection. When the card shaft 3 is firmly clamped, multiple connecting belts 3 19 will cooperate closely with the connecting belts 1 2 and 2 12, and are methodically wrapped around the head. This wrap-around fixing method can ensure that the respirator is still firmly fitted when the user moves quickly or violently, and will not easily loosen or fall off. When the emergency escape respirator is not needed temporarily, its convenient structural design allows the user to easily tie it to the body or backpack, effectively avoiding loss due to panic, and adding reliable assistance to safety protection in emergency moments.
[0013] When the circular shaft 14 is inserted into the circular grooves 17 at different positions, the relative positions and connection lengths between the various components of the respirator are changed, thereby realizing flexible adjustment of the overall length of the respirator. This design is not only easy to operate, but also can quickly and accurately meet the personalized needs of different users for the length of the respirator in an emergency, ensuring that the user has a comfortable and safe wearing experience during the escape process, and effectively improving the efficiency of emergency escape.
