Through the structural design of the filtering mechanism 4, it can be known that when a fire occurs, smoke is discharged through the ventilation duct 1, and dust impurities in the discharged smoke can be filtered through the filtering mechanism 4, thereby reducing pollution to the environment.

[0031] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0032] Embodiment 1:

[0033] Please refer to Figure 1-Figure 6 An indoor fire-fighting ventilation device comprises a ventilation duct 1, an air inlet of the ventilation duct 1 is provided with an air inlet mechanism 2, an air outlet of the ventilation duct 1 at one end away from the air inlet mechanism 2 is detachably connected with a second louver 19, a mounting groove is provided at one end of the lower end of the ventilation duct 1 close to the air inlet mechanism 2, a filter mechanism 4 is provided inside the mounting groove, and a smoke exhaust mechanism 3 is provided inside the ventilation duct 1 and at a side of the filter mechanism 4 away from the air inlet mechanism 2.

[0034] Through the above structural design, it can be known that the smoke can be discharged through the ventilation duct 1, the dust and impurities in the smoke can be filtered and processed through the filtering mechanism 4 to reduce air pollution, and the smoke inside the ventilation duct 1 can be quickly discharged through the smoke exhaust mechanism 3.

[0035] Specifically, the filtering mechanism 4 includes a connecting frame 5, which is plugged into the mounting groove, a filter screen 6 is fixedly connected to the middle of the connecting frame 5, a handle 7 is fixedly connected to the middle of the lower end of the connecting frame 5, cavities are provided at both ends of the lower end of the connecting frame 5, and a first limiting mechanism 9 is provided inside the cavity.

[0036] Through the above structural design, it can be known that the connecting frame 5 can be installed inside the installation groove through the first limiting mechanism 9, and the dust and impurities in the smoke discharged from the ventilation duct 1 can be filtered through the filter screen 6.

[0037] Specifically, the first limiting mechanism 9 includes a spring 11, which is located inside the cavity. One end of the spring 11 is fixedly connected to the inside of the cavity, and the other end of the spring 11 is fixedly connected to a plug-in block 10. The plug-in block 10 is slidably connected to the cavity. The plug-in block 10 is plugged into one side of the mounting groove. A slide groove 8 is provided at the lower end of the connecting frame 5 and at a position corresponding to the cavity. The slide groove 8 is connected to the cavity. The lower end of the plug-in block 10 located inside the cavity is fixedly connected to a first connecting block 12. One end of the first connecting block 12 away from the plug-in block 10 extends through the slide groove 8 to the outside of the lower end of the connecting frame 5, and the first connecting block 12 is slidably connected to the slide groove 8.

[0038] Through the above structural design, it can be known that when it is necessary to remove the filter mechanism 4 from the inside of the installation groove to clean the dust and impurities on the filter screen 6, the first connecting blocks 12 at both ends of the lower end of the connecting frame 5 can be pulled toward one end close to each other, so that the first connecting block 12 drives the plug-in block 10 to slide toward the inside of the cavity. When the plug-in block 10 slides toward the inside of the cavity, the plug-in block 10 is separated from the plug-in on the inner side of the installation groove, and at the same time, the plug-in block 10 squeezes the spring 11, and the spring 11 stores the squeezing force. After the plug-in block 10 is separated from the installation groove, the handle 7 can be pulled downward, so that the handle 7 drives the connecting frame 5 to move toward the outside of the installation groove. After the connecting frame 5 is pulled out, the spring 11 releases the stored force to push the plug-in block 10 and the first connecting block 12 to reset. After the connecting frame 5 is completely pulled out, the filter screen 6 can be cleaned.

[0039] Specifically, the air intake mechanism 2 includes an air intake shell 16, and the air inlet of the air intake shell 16 is detachably connected to the first louver 18. The end of the air intake shell 16 close to the ventilation duct 1 is fixedly connected to a plug-in rack 17, and the plug-in rack 17 is plug-connected to the ventilation duct 1. A plurality of second limiting mechanisms 20 are arranged on the outside of the ventilation duct 1 and at positions corresponding to the plug-in rack 17.

[0040] Through the above-mentioned structural design, indoor smoke can enter the interior of the ventilation duct 1 through the position of the air inlet shell 16, and the air inlet shell 16 can be connected to the ventilation duct 1 by plugging the plug-in frame 17 into the ventilation duct 1. The connection between the plug-in frame 17 and the ventilation duct 1 can be fixed by the second limiting mechanism 20.

[0041] Specifically, the second limiting mechanism 20 includes a second connecting block 21 and a nut 23. The second connecting block 21 is located on the outside of the ventilation duct 1 and corresponds to the position of the plug-in frame 17. The lower end of the second connecting block 21 is fixedly connected to a screw rod 22. Plug-in grooves are provided at positions corresponding to the ventilation duct 1, the plug-in frame 17 and the screw rod 22. One end of the screw rod 22 away from the second connecting block 21 passes through the plug-in grooves provided on the ventilation duct 1 and the plug-in frame 17 and extends to the interior of the ventilation duct 1. The nut 23 is located inside the ventilation duct 1 and corresponds to the screw rod 22. The nut 23 is threadedly connected to the screw rod 22.

[0042] Through the above structural design, it can be known that when the air intake mechanism 2 needs to be removed from the ventilation duct 1, the first louver 18 can be removed from the air intake shell 16 first. After the first louver 18 is removed, by rotating the nut 23, the connection between the nut 23 and the screw 22 is separated when the nut 23 is rotated. After the nut 23 is separated from the screw 22, the second connecting block 21 can be pulled away from the ventilation duct 1, so that the second connecting block 21 pulls the screw 22 out of the plug-in slot between the ventilation duct 1 and the plug-in frame 17, and then the air intake shell 16 is pulled to the end away from the ventilation duct 1, and then the air intake shell 16 drives the plug-in frame 17 to separate the connection with the ventilation duct 1, thereby completing the air intake mechanism 2 and removing the air intake mechanism 2 from the ventilation duct 1.

[0043] Embodiment 2:

[0044] The indoor fire-fighting ventilation device provided in Example 1 is further optimized. Specifically, Figure 7 As shown, the smoke exhaust mechanism 3 includes a motor 13, which is located in the middle position of the ventilation duct 1. In order to fix the motor 13 in the middle position of the ventilation duct 1, the motor 13 is fixedly connected with connecting rods 15 around one end close to the filter 6, and the end of the connecting rod 15 away from the motor 13 is fixedly connected to the inside of the ventilation duct 1, and the output end of the motor 13 away from the end of the connecting rod 15 is fixedly connected with a fan blade 14.

[0045] Through the above structural design, it can be known that when it is necessary to accelerate the discharge of smoke inside the ventilation duct 1, the motor 13 can be started. After the motor 13 is started, the output end of the motor 13 drives the fan blade 14 to rotate with the center of the circle of the output end of the motor 13 as the axis. The rotation of the fan blade 14 can accelerate the discharge of smoke inside the ventilation duct 1.
