[0024] Reference Figure 1 and Figure 2 The battery pack 4 is installed on the lower part of the fixed cylinder 11 on the side closest to the room. The battery pack 4 is fixedly connected to the fixed cylinder 11 by screws. A directional arrow is installed on the surface of the battery pack 4, and the directional arrow can be lit.

[0025] Reference Figure 1 and Figure 2 The emergency light 5 is installed at the lower part of the fixed cylinder 11. There are two emergency lights 5, which are located at both ends of the long side of the battery pack 4. The emergency lights 5 are fixedly connected to the fixed cylinder 11 by screws and use LED light source.

[0026] Reference Figure 1 and Figure 2 In this embodiment, the battery pack 4 is used to power the drive motor 12, controller 14, gas detection probe 2, audible and visual alarm 3, and emergency lighting 5.

[0027] The implementation principle of Example 1 is as follows: A high-sensitivity gas sensor probe monitors the concentration of combustible gas in the environment in real time. When the concentration reaches a certain level, the alarm system is automatically triggered. The audible and visual alarm 3 is graded according to the leakage concentration. When the concentration is low, a slow flashing light and a medium decibel warning bell are used. When the concentration is high, a fast flashing light and a high decibel warning bell are used. The emergency lighting 5 automatically lights up in the event of a power outage to provide emergency lighting. The battery pack 4 can support the operation of the fan, audible and visual alarm, detector and controller 14 in the event of a power outage, and discharge the indoor gas to the external environment.

[0028] Example 2 The difference between Example 2 and Example 1 is that in Example 2, the fixing cylinder 11 can be better fixed to the corresponding position of the wall.

[0029] Reference Figure 3 and Figure 4 Each corner of the fixed cylinder 11 is provided with a through hole, and the inner cavity of each through hole is provided with a positioning device 6. The positioning device 6 includes a fixing nail 61. In this embodiment, the fixing nail 61 is preferably a conical nail body. The large end of the fixing nail 61 is attached to the fixed cylinder 11.

The adjusting block 63 is coaxially fixedly connected to the adjusting bolt 62 by welding.

[0032] Reference Figure 3 and Figure 4 The sidewall of the adjusting block 63 is evenly distributed with multiple protrusions 64. The edges of the protrusions 64 smoothly transition with the sidewall of the adjusting block 63, and the end face of each protrusion 64 away from the adjusting block 63 is an arc-shaped end face.

[0033] Reference Figure 3 and Figure 4Each insertion slot 612 has an insertion rod 65 inside its cavity. The insertion rod 65 passes through the insertion slot 612 and can slide along the opening direction of the insertion slot 612. The end face of the insertion rod 65 near the abutment block is always in contact with the abutment block or protrusion 64. Positioning pins are arranged in an array at the end of the insertion rod 65.

[0034] The implementation principle of Example 2 is as follows: When the operator installs the fan, he first inserts the fixing nail 61 into the wall, and then rotates the adjusting bolt 62 so that the plug rod 65 abuts against the protrusion 64 and is pushed out from the plug groove 612, which further improves the stability of the installation.
