Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense doors, in particular to a civil air defense door with a ventilation structure. Background Art

[0002] Civil defense, also known as civil defense, is an activity in which the government mobilizes and organizes the masses to take anti-air raid, disaster relief measures, implement rescue operations, and prevent and reduce disaster hazards. Civil defense doors are doors at the entrances and exits of civil defense projects, used to protect people's safety during special periods. For example, a ventilation device for civil defense doors is recorded in the patent with patent announcement number CN220378136U, in which the scheme recorded absorbs the heat inside the door body through heat dissipation fins and dissipates it outwards, while the ventilation slots ventilate the inner cavity of the door body, effectively speeding up air circulation and preventing heat accumulation in the inner cavity of the door body. The coolant is transmitted to the inner cavity of the sleeve through the injection pipe, and the sleeve cools the inner cavity of the door body. The fan is operated to absorb and transmit external air to the inner cavity of the door body, and the outside air enters the inner cavity of the door body to dissipate the heat. The dissipated heat will be discharged through the ventilation slots, thereby realizing the rapid heat dissipation and ventilation operation of the door body, effectively preventing the civil defense door from being in a closed state, and heat is easily accumulated, causing the civil defense door to be damaged and deformed due to high temperature. However, the solution in this case has the following problems: First, the ventilation slots are always in an open state. When special circumstances occur, they cannot be closed, and outside air can still enter the door through the ventilation slots, posing a safety risk. Second, there is a lack of gas purification equipment at the location of the ventilation slots, and the outside air entering the room through the ventilation slots cannot be filtered and treated, posing a safety hazard.

[0003] Based on this, civil air defense doors with ventilation structures are now provided to eliminate the drawbacks of existing devices. Utility Model Content
