[0034] Implementation Method 1

[0035] Reference Figures 1 to 4 This embodiment is an optional embodiment of the present application, which discloses a soundproof enclosure with an automatic opening function in case of fire, including an enclosure body 1, each side of the enclosure body 1 is provided with at least one air inlet, each of the air inlets is provided with an air inlet muffler 2, and at least one exhaust port is provided at the top of the enclosure body 1, and an exhaust muffler 3 is provided in the exhaust port; it should be noted that the number of the air inlets and the exhaust ports is determined according to needs;

[0036] A soundproof door 11 is hinged on the front or any other side of the cover body 1, and a sound-absorbing and insulating module 4 is bonded to each side of the cover body 1. It should be pointed out that the sound-absorbing and insulating module 4 and the soundproof door 11 are made of commonly used sound-absorbing and insulating materials, such as metal plates or non-metal plates combined with rock wool, glass wool, melamine wool, sand-based sound-absorbing and insulating materials, foam ceramics, foam aluminum, etc.

[0044] The perforated plate 602 and the glass fiber layer 605 can cooperate with each other to isolate and absorb the noise generated by the source, thereby ensuring the sound insulation effect; at the same time, the density of the entire rotating fan 6 can be further increased by setting the cement limit plate 604 and the rubber-plastic plate 606, thereby further improving the sound insulation effect;
