Alternatively, compression spring 400 is fabricated from a high temperature resistant steel material. In this way, the influence of high temperature on the compression spring 400 can be reduced, the condition that the elastic force of the compression spring 400 is reduced due to high temperature can be prevented, and the stability of the compression spring 400 is improved, so that more stable elastic force can be provided for the second plate 200.
Optionally, the lengths of the compression springs 400 in the free state are different from each other. In this way, when the compression spring 400 ejects the second plate 200 out of the first chamber 101, the second plate 200 can be inclined to be positioned below the first plate 100, so that the second plate 200 has a guiding effect on the inert gas in the first chamber 101, the inert gas can be guided to the position of the fire in the chamber, and the second plate 200 can be inclined to be directed to the fire point, so that the fire extinguishing powder can be sprayed to the fire place, and the fire extinguishing efficiency can be improved.
Alternatively, the area of the opening 102 is the same as the area of the cross section of the second plate 200, and the area of the opening 102 is greater than or equal to one third of the area of the cross section of the first plate 100 and less than or equal to the area of the cross section of the first plate 100. In this way, the second plate 200 can completely close the opening 102, so that gaps can be prevented from remaining between the second plate 200 and the opening 102, the integrity of the plate is enhanced, the area of the opening 102 is set to be more than or equal to one third of the cross-sectional area of the first plate 100 and less than or equal to the cross-sectional area of the first plate 100, the area of the opening 102 is in a reasonable range, the arrangement of the opening 102 on the lower side surface of the first plate 100 is more coordinated, the installation of the second plate 200 on the first plate 100 is more symmetrical, the ornamental value of the plate is improved, the aesthetic degree of the plate is enhanced, the first chamber 101 and the second chamber 201 can be reasonably designed, and not only the first chamber 101 can have enough space to be filled with inert gas, but also the second chamber 201 can have enough space to be filled with fire extinguishing powder.
Alternatively, the opening 102 and the second plate 200 may be designed to have any shape, and the shape of the opening 102 is adapted to the shape of the second plate 200, preferably, the opening 102 and the second plate 200 are rectangular, or may be circular or polygonal. In this way, by arranging the opening 102 and the second plate 200 corresponding to and adapted to the opening 102 on the first plate 100, the opening 102 and the second plate 200 can form various patterns on the first plate 100, so that the plate is more beautiful indoors, the aesthetic degree of the plate is enhanced, and the ornamental value of the plate is improved.
As shown in fig. 9, optionally, a power chamber 203 is provided inside the second chamber 201, and the power chamber 203 has compressed gas therein. In this way, the pressure in the second chamber 201 can be increased by using the compressed gas in the power chamber 203, so that the air pressure in the second chamber 201 is larger than the external atmospheric pressure, and the fire-extinguishing powder in the second chamber 201 can be sprayed out through the discharge port quickly, so that the discharge speed of the fire-extinguishing powder is improved, the fire-extinguishing powder is discharged in a spraying mode, the fire-extinguishing powder can be discharged farther, the fire-extinguishing range of a plate is enlarged, the fire-extinguishing effect of the plate is enhanced, and the fire-extinguishing performance is improved.
