There is a certain gap between the outlet box 3 and the sliding plate 56. The gap between the outlet box 3 and the sliding plate 56 is filled with a liquid coolant

[0030] In this embodiment, the ash prevention component 6 includes a first filter screen 61. The first filter screen 61 is fixedly installed on the outer side of the interface 2. A second filter screen 62 is fixedly installed on the outer side of the outlet box 3. A third filter screen 63 is fixedly installed on the outer side of the outlet box 3.

[0031] The working principle of the above technical solution is as follows:

[0032] First, by filling the gap between the outlet box 3 and the sliding plate 56 with a liquid coolant, when the temperature in the pipeline rises due to a fire source and reaches the threshold of the temperature sensor 58, the temperature sensor 58 transmits a signal to the controller. The controller then activates the hydraulic actuator 55, which pushes the sliding plate 56 through the hydraulic actuator 55 to squeeze, so that the liquid coolant breaks through the plastic film 59, and the liquid coolant rushes into the gap between the outer pipe 1 and the inner pipe 4, thereby achieving the effect of enhancing the flame retardancy of the ventilation pipe. During normal use, the electric fan is used for exhausting air, and the air flow enters the pipeline through the interface 2, and the dust and textile fibers are filtered through the first filter screen 61, the second filter screen 62 and the third filter screen 63. The spraying device can also further achieve the filtering effect. When a fire breaks out, the electric fan is controlled to turn over, and the water mist sprayed at this time is sucked into the pipeline, playing a role in extinguishing the fire and reducing the temperature.

[0033] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0034] 1. By providing a fire prevention component, which fills the gap between the outlet box and the sliding plate with a liquid coolant. At the same time, when a fire source is detected and the temperature in the pipeline rises to reach the threshold of the temperature sensor, the hydraulic actuator is activated. Then, the sliding plate is pushed by the hydraulic actuator to squeeze, so that the liquid coolant breaks through the plastic film, and the liquid coolant rushes into the gap between the outer pipe and the inner pipe. Thus, based on the principle that the boiling point of the liquid cooler is lower than the ignition point of the pipeline and its evaporation heat absorption effect, the flame retardant effect is achieved, making the device have a good flame retardant effect. Additionally
