AI Technical Summary
Existing fire escape emergency lights suffer a significant decrease in illumination effectiveness in dense smoke environments during fires, as smoke obscures the light and fails to effectively guide escape routes.
A smoke guiding assembly comprising a guide box, a guide grille, and a guide fan was designed. The smoke is guided into the guide box through the guide box and the guide grille, and discharged by the guide fan, thereby reducing the smoke concentration around the lighting fixture.
It significantly improves the lighting effect of fire escape emergency lights in dense smoke environments during fires, ensuring that escape routes are brightly visible.

Abstract
Description
A type of fire escape emergency light Technical Field
[0001] This utility model relates to the field of fire escape indicator equipment technology, and in particular to a fire escape emergency light. Background Technology
[0002] Existing fire escape emergency lights can achieve good emergency lighting effects in ordinary power outage scenarios. However, in the event of an earthquake or fire, due to the collapse of building walls or the burning of building materials, a large amount of smoke will be present in the escape route environment. When this smoke drifts around or adheres to the lighting of the fire escape emergency lights, it will block the light, causing the lighting effect of the fire escape emergency lights to decrease significantly in the dense smoke environment of a fire.
[0003] Therefore, the applicant has developed a fire escape emergency light to solve the above problems. Summary of the Invention

[0032] As shown in Figures 1-6, a fire escape emergency light includes:
[0033] A smoke guiding assembly includes a guiding box 3, a guiding grille 4, a guiding port, and a guiding fan 6. The guiding box 3 has openings at both the left and right ends and is equipped with the guiding fan 6 at each end. The guiding grilles 4 are horizontally arranged on the front and rear sides inside the guiding box 3, and an installation space is left between the two sets of guiding grilles 4. The top of the guiding box 3 has guiding ports on the front and rear sides, and the guiding ports are connected to the guiding channels 5 of the corresponding guiding grilles 4. The guiding fan 6 is connected to the guiding channels 5 of the guiding grilles 4.
[0034] Emergency light housing 1, the flow guide box 3 is fixed to the top of the emergency light housing 1, and the flow guide fan 6 is connected to the battery inside the emergency light housing 1;
[0035] Lighting lamp 2 is disposed above the smoke deflector assembly and connected to the battery. Lighting lamp 2 is connected to the top of the emergency light housing 1 via mounting bracket 8, which is disposed within the installation space.
[0036] As shown in Figure 1, in one embodiment, the flow guide port is provided with a flow guide channel 5, which is a funnel-shaped structure with a small upper port and a large lower port. This allows the smoke below the lighting lamp 2 to quickly enter the flow guide box 3 and prevents backflow.
[0037] As shown in Figure 2, in one embodiment, the flow guide grille 4 includes several flow guide plates spaced apart front and rear, and the flow guide plates are corrugated plates. This effectively prevents smoke from flowing back upwards.
[0038] As shown in Figure 6, in one embodiment, the airflow fan 6 is connected to the battery by a wire, and the wire extends through the installation space and through the wire hole 9 into the emergency light housing 1.
[0039] In one embodiment, the four corners of the airflow fan 6 are fixedly connected to the ports of the airflow box 3 by screws.
[0040] In one embodiment, the smoke guiding assembly is a structure made of heat-insulating material. This reduces the impact of high-temperature smoke on the lighting lamp 3 and the emergency light housing 1.
[0041] As shown in Figures 3 and 6, in one embodiment, the flow guide box 3 has a concave structure after being rotated 90 degrees clockwise. Two sets of flow guide grilles 4 are arranged on the front and rear sides of the concave structure. The notch in the concave structure serves as the installation space. The bottom of the flow guide box 3 is provided with a retaining plate 10, and the top of the emergency light housing 1 is provided with a sliding slot 11. The flow guide box 3 is horizontally inserted into the sliding slot 11 through the retaining plate 10 and engages with the top of the emergency light housing. This facilitates the rapid installation of the smoke flow guide assembly, allows the installation of the lighting lamp 2 first, followed by the installation of the smoke flow guide assembly, and also facilitates maintenance.
[0042] In one embodiment, the outlet of the air-guiding fan 6 is connected to an arc-shaped air-guiding shroud 7, the outlet of which faces downward. This guides the smoke at the outlet downward, thereby preventing the smoke from returning to the vicinity of the lighting lamp 2.
[0043] The fire escape emergency light proposed in this utility model uses a smoke diversion component installed under the light to draw smoke and dust that is about to reach the light into the diversion box and then discharge it after passing through the diversion grille. This significantly reduces the smoke content near the light and improves the lighting effect of the fire escape emergency light in the dense smoke environment of a fire.
[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
