[0023] Specifically, the testing component includes a mounting bracket 3 installed inside the mounting slot 2. A ventilation hood 4 is screwed to the bottom of the mounting bracket 3. Fixing parts 5 are fixedly connected to both sides of the mounting bracket 3 near the top. A control module 6 is installed at the bottom inside the mounting bracket 3. An audible and visual alarm 7 is installed on one side of the mounting bracket 3. Two smoke sensors 8 are installed on one side of the mounting bracket 3. A fan 9 is installed inside the ventilation hood 4. Multiple air inlets 10 arranged in a circular pattern are opened on the outside of the ventilation hood 4. Multiple first through holes 11 arranged in a circular pattern are opened on the top of the mounting bracket 3. A groove 12 is opened on the top of the base 1. Multiple second through holes 121 arranged in a circular pattern are opened at the bottom of the groove 12. The first through holes 11 and the second through holes 121 communicate with each other. The fixing parts 5 are movably connected to the mounting slot 2.

[0024] The ventilation hood 4 is made of red transparent plastic. The fan 9 inside the ventilation hood 4 can accelerate the airflow rate. The air can carry the smoke into the mounting bracket 3 through the air inlet 10. Then the air is discharged through the first through hole 11 and the second through hole 121 to accelerate the airflow rate. The control module 6 inside the mounting bracket 3 is electrically connected to the audible and visual alarm 7 and the smoke sensor 8. The smoke sensor 8 can detect the smoke in the air. Then the control module 6 activates the audible and visual alarm 7 to issue an audible and visual alarm, improving the timeliness and practicality of the equipment in responding to fire alarms.

[0025] More specifically, the locking mechanism includes movable cavities 101 respectively opened on both sides of the base 1. A connecting plate 13 is slidably connected to the inside of the movable cavity 101. A locking post 14 is connected to one side of the connecting plate 13. A spring 15 is fixedly connected between the movable cavity 101 and the connecting plate 13. A pull rod 16 is fixedly connected to the other side of the connecting plate 13 near one end. Locking slots 17 are opened on both sides of the mounting bracket 3. Screws 18 are installed on both sides of the base 1 and extending out of the movable cavity 101. One end of the screw 18 is connected to a limiting part 19. A push block 20 is fitted on the outside of the limiting part 19. Fixing strips 21 are installed on the top of the inner side of the mounting slot 2 and near both sides. A notch 22 is opened at the top of the fixing part 5. A guide rod 23 passes through the inner side of the movable cavity 101. The guide rod 23 passes through the connecting plate 13 and is slidably connected to it. The fixing strip 21 is slidably connected to the notch 22. The limiting part 19 is rotatably connected to the push block 20. The screw 18 is screwed to the base 1.

[0026] Furthermore, both the fixing strip 21 and the notch 22 have a "convex" cross-section. The notch 22 can limit and fix the mounting bracket 3 on one side of the fixing part 5 through the fixing strip 21. The guide rod 23 can guide and limit the connecting plate 13. The spring 15 on the outside of the guide rod 23 can squeeze the connecting plate 13, so that the connecting plate 13 drives the locking post 14 to insert into the locking groove 17 to lock and fix the mounting bracket 3. The screw 18 can drive the pushing block 20 to move through the limiting part 19, so that the pushing block 20 can squeeze and push the connecting plate 13 again, thereby doubly fixing the connecting plate 13, improving the stability of the fixed mounting bracket 3 and the convenience of subsequent maintenance of the mounting bracket 3.

At the same time, the fixing parts 5 on both sides of the mounting bracket 3 are also inserted into the mounting groove 2, and the fixing strip 21 slides into the notch 22. Then, the pulling rod is slowly released. At this time, the guide rod 23 guides and limits the connecting plate 13. At the same time, the spring 15 on the outside of the guide rod 23 presses the connecting plate 13. Then, the connecting plate 13 drives the locking pin 14 to insert into the locking groove 17 to lock and fix the mounting bracket 3. Then, the screw 18 drives the pushing block 20 to move through the limiting part 19. At this time, the pushing block 20 presses and pushes the connecting plate 13 again.

[0028] Furthermore, the fan 9 inside the ventilation hood 4 is activated to accelerate the airflow rate. At this time, the air carries the smoke into the mounting bracket 3 through the air inlet 10. Then the air is discharged through the first through hole 11 and the second through hole 121. At the same time, the smoke sensor 8 detects the smoke in the air, and then the control module 6 activates the audible and visual alarm 7 to issue an audible and visual alarm.
