When a fire occurs inside the building, the emergency host 1 is activated, and the LED backlight behind the light-transmitting indicator panel 8 located in the middle section of the host panel 9 lights up. Through the light-transmitting indicator panels 8 of different colors and the light-transmitting evacuation indicator arrows 7, clear visual guidance is provided for people to escape. The direction pointed to by the light-transmitting evacuation indicator arrows 7 is the direction of the safety exit. Its unique design allows people to quickly identify the escape direction in a smoke-filled environment.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, multiple status indicator lights 4 are equidistantly arranged inside the upper right center of the emergency host 1, and a host power socket 5 is located inside the lower right center of the emergency host 1. The status indicator lights 4 are used to display the working status of the emergency host 1. For example, different colored status indicator lights 4 can indicate whether the emergency host 1 is working properly, whether the power supply is sufficient, etc. In this way, rescuers can quickly understand the operation status of the emergency evacuation guidance device from a distance, so as to take appropriate measures in a timely manner. After connecting an external power cord to the host power socket 5, the internal power supply of the emergency host 1 can be directly charged and powered. Under normal circumstances, the emergency host 1 can be kept charging through the external power cord to ensure that the internal power supply is sufficient. When a fire causes the external power supply to be interrupted, the internal power supply of the emergency host 1 automatically switches to the power supply mode to provide continuous power support for the entire emergency evacuation guidance device. The rear end of the emergency host 1 is equipped with Equipped with a hanging bracket 10, the emergency host 1 has two internally located loudspeakers 11 on the left and right sides at the bottom center. These loudspeakers 11 emit audible alerts during a fire, guiding evacuees in the correct direction. They can also play pre-recorded evacuation instructions, such as "Please evacuate in the direction of the arrow," helping those who may have poor eyesight or other reasons to quickly find their way out. During a fire, the emergency host 1, as the core of the entire system, coordinates the operation of all components. Upon receiving a fire alarm signal, it immediately activates the LED backlight, emergency lighting 2, status indicator lights 4, and loudspeakers 11, while simultaneously supplying power to the auxiliary evacuation device 6. The hanging bracket 10 ensures the emergency host 1 is securely installed in a suitable location inside the building, preventing it from falling or being damaged in emergencies such as fires. All components work together to provide comprehensive emergency evacuation instructions, improving the escape success rate of people inside the building.

[0024] like Figure 1 and Figure 5As shown, the emergency host 1 is equipped with auxiliary evacuation devices 6 connected to its outer perimeter and bottom. The auxiliary evacuation devices 6 include a miniature blower box 12, a hollow air supply duct 13, a rectangular hollow air distribution frame 14, an air outlet 15, a screw fixing plate 16, and an air inlet 17. The miniature blower box 12 has a screw fixing plate 16 at its top, which is fixed to the center of the outer wall at the bottom of the emergency host 1 with screws. The miniature blower box 12 has an air outlet at its front end, connected to the hollow air supply duct 13. The top of the hollow air supply duct 13 is connected to the rectangular hollow air distribution frame 14, which is fitted around the front perimeter of the emergency host 1. The rectangular hollow wind distribution frame 14 has multiple air outlets 15 equidistantly arranged inside its front end. The miniature blower box 12 has air inlets 17 at both ends. The air outlets are connected to the inside of the rectangular hollow wind distribution frame 14 through the hollow air supply pipe 13. This allows the air generated by the miniature blower to be smoothly delivered to the rectangular hollow wind distribution frame 14. The rectangular hollow wind distribution frame 14 is fitted around the front end of the emergency host 1. This design does not affect the normal operation of the emergency host 1 and can effectively disperse smoke in front of it when a fire occurs. The multiple air outlets 15 are arranged in a rectangular pattern inside the front end of the rectangular hollow wind distribution frame 14 at equal intervals.

[0025] like Figure 1 and Figure 5 As shown, a miniature blower box 12 contains a miniature blower. The miniature blower blows air into the rectangular hollow air distribution frame 14 through the air outlet and the hollow air supply pipe 13. The miniature blower box 12 is electrically connected to the internal power supply of the emergency host 1 via a wire. The miniature blower inside the miniature blower box 12 starts working after the emergency host 1 is started. The miniature blower draws in air through the air inlet 17, pressurizes the air, and discharges it from the air outlet. The discharged air enters the rectangular hollow air distribution frame 14 through the hollow air supply pipe 13. Because multiple air outlets 15 are arranged in a rectangular trajectory at equal intervals inside the front end of the rectangular hollow air distribution frame 14, the air can be blown out evenly from the air outlets 15, forming a... A forward airflow is formed to disperse the smoke surrounding the fire emergency evacuation indicator. The miniature blower box 12 is electrically connected to the internal power supply of the emergency host 1 via wires, and is powered by the emergency host 1. When a fire occurs, the emergency host 1 will start and simultaneously power the auxiliary evacuation device 6 to ensure that the miniature blower can work in time. The auxiliary evacuation device 6 works in coordination with other components of the emergency host 1 to provide clear evacuation instructions for escapees. When the light-transmitting indicator panel 8 and the light-transmitting evacuation indicator arrow 7 indicate the escape direction, the auxiliary evacuation device 6 disperses the smoke so that escapees can accurately see the indicator arrow, improving the efficiency and accuracy of the escape.
