[0002] Doors are the most common type of furniture in our daily home decoration. With the development of the times and the improvement of people's living standards, our requirements for doors are no longer limited to sheltering from wind and rain and serving as decorations. Instead, we increasingly value doors' ability to provide higher security for our daily lives. For example, when a fire suddenly occurs in the home, the doors need to have certain fire-resistant capabilities.

[0003] For example, the Chinese patent with publication number CN109653665A discloses a fire door disclosed by the present invention, including a main body, a handle, a fire extinguishing mechanism, a shell and a smoking mechanism, the fire extinguishing mechanism includes a heat absorption component and a spraying component, the heat absorption component includes a water pump, a heat absorption plate, a heat absorption pipe and a stabilizing component, the spraying component includes a driving chamber, a driving unit and a spraying unit, and the smoking mechanism includes a rotating component and a smoking component. The fire extinguishing mechanism effectively prevents the main body from being deformed by heat, and the nozzle sprays and extinguishes the fire in all directions and evenly, effectively slowing down the spread of the fire, playing a protective role, and greatly improving the practicality and reliability of the fire door.

[0004] Although this type of fire door leaf utilizes a fire extinguishing mechanism to prevent the main body from being deformed by heat, thereby improving the practicality and reliability of the fire door, when a fire occurs, this type of fire door leaf cannot absorb harmful gases and also does not have a good heat insulation effect.

[0032] When a fire occurs, the decorative panel is first melted by the high temperature and leaks out of the water spray plate. The second valve is opened, and the water pump draws the tap water in the water storage chamber into the water spray chamber of the water spray plate. Because the thickness of the water spray chamber is relatively thin, the tap water can quickly fill the water spray chamber. As the water pump operates, the water pressure in the water spray chamber increases, and the water pressure is used to spray water through the water spray hole, thereby reducing the spread of fire and improving the usability of the technical solution.

[0033] Furthermore, a vacuum pump is provided in the first groove, an air suction hole is provided in the first groove, the vacuum pump is horizontally arranged in the first groove, a first valve is provided at the air suction hole, and a filter is provided at the overlapped position of the side plate and the first groove.

[0092] When a fire occurs, the decorative panel 324 is first melted by the high temperature and leaks out of the water spray plate 320. The second valve 311 is opened, and the water pump 310 pumps the tap water in the water storage chamber 140 into the water spray chamber 322 of the water spray plate 320. Because the thickness of the water spray chamber 322 is relatively thin, the tap water can quickly fill the water spray chamber 322. As the water pump 310 operates, the water pressure in the water spray chamber 322 increases, and the water pressure is used to spray water through the water spray hole 321, thereby reducing the spread of fire and improving the usability of the present technical solution.

[0097] When a fire occurs, the water pump 310 extracts water from the water storage chamber 140 and then uses the water spray plate 320 to spray the water to the flame to reduce the spread of the fire. When the tap water in the water storage chamber 140 is used up, the second valve 311 is closed, the first valve 331 is opened, and the vacuum pump 330 starts to operate to extract air from the water storage chamber 140 to make the water storage chamber 140 a vacuum state, which greatly improves the thermal insulation of the present technical solution.

[0101] The air intake unit 240 includes:

[0102] An air pump 241, wherein the air pump 241 is horizontally placed in the third groove 125;

[0103] An air suction plate 242, wherein the air suction plate 242 is disposed between the slide slot 220 and the arch plate 120;

[0104] An air suction cavity is provided in the air suction plate 242, and a plurality of air suction holes 243 are provided on one side of the air suction plate 242. The air suction holes 243 are provided corresponding to the absorption cavity 211 of the absorption plate 210. An air suction port 244 is provided on the other side of the air suction plate 242 relative to the side where the air suction holes 243 are provided. The air inlet of the air pump 241 is connected to the air suction port 244 through an air pipe, and a through groove 126 is provided between the first groove 121 and the third groove 125.

[0105] In this design, the absorption plate 210 is made of glass fiber mesh cloth, and a third groove 125 is provided between the first groove 121 and the second groove 123 of the arch plate 120 , and the opening of the third groove 125 is consistent with the first groove 121 and the second groove 123 .

[0106] In the present technical solution, the absorption module 200 is also provided with an air suction part 240, and the air suction part 240 is composed of an air pump 241 and an air suction plate 242. The air pump 241 is horizontally placed in the third groove 125, and the air suction plate 242 is placed between the slide groove 220 and the bow plate 120.
