In the invention, when local rainstorm occurs in typhoon crossing, the drainage system can not drain water in time, and water is easy to accumulate on the groundThe accumulated water can even enter a household at the bottom layer in a spreading manner, because the speed of the accumulated water filling is very fast, people are often difficult to timely drain the accumulated water, the water level can continuously rise to the position of the sofa cushion, when the water level rises to the positions of the first mounting groove 17 and the second mounting groove 18 in the base 1, the starting mechanism 21 on the second inflatable air bag 15 can be continuously soaked in the water, the sponge cloth in the filling groove 20 can rapidly absorb the water, after the sponge cloth absorbs the water and is saturated, the water can naturally penetrate through the sponge cloth and enter the filling groove 20, the water-absorbing resin in the filling groove 20 absorbs the water, after the water-absorbing resin expands and grows, the expanded water-absorbing resin can extrude the sliding groove 22 and extrude the linkage shaft 23, the linkage shaft 23 moves under the extrusion acting force, and when the linkage shaft 23 moves outwards, the U-shaped shaft 25 can be driven, The pull ring 26 moves synchronously, the movement of the pull ring 26 drives the second air valve 24, the second air valve 24 is opened, and the high-pressure CO stored in the second inflatable air bag 15₂The filling in the second inflatable air bag 15 can be rapidly released, then the corresponding expansion of the second inflatable air bag 15 is popped out from the first mounting groove 17 or the second mounting groove 18, one expanded second inflatable air bag 15 can provide the buoyancy effect of at least 25kg, and a plurality of second inflatable air bags 15 arranged around the base 1 act together, so that enough buoyancy can be provided, the whole sofa can float on the water surface, and the whole safety is effectively ensured.

The surface of the leather has a certain waterproof function, but accumulated water can still permeate into the joint between the leathers, and the filler in the sofa is easy to cause mildewing and rotting of the internal structure when water enters, so that the first expansion water stop strip 10 or the second expansion water stop strip 27 is arranged at the joint between the seat cushion 3 and the handrail 2, the first expansion water stop strip 10 and the second expansion water stop strip 27 can also expand after absorbing water, the two sides are pressed after expanding, the second expansion water stop strip 27 cannot permeate water and has pressing effect on the two sides, the joint is more compact, and the accumulated water can be effectively prevented from permeating; if the buoyancy provided by each second inflatable air bag 15 is still insufficient, the user can rotate the rotating plate 8 to take the first inflatable air bag 7 out of the interior, open the first air valve 9 to inflate the first inflatable air bag, and the inflated first inflatable air bag 7 can increase the overall buoyancy of the sofa to play an auxiliary role.

The inner box 12 installed below the seat cushion 3 can be used as a supporting structure for the seat cushion 3, and also has a storage effect, and the adjacent ends of the two seat cushions 3 are fixed in a mutual pressing manner to be broken, so that objects can be stored in the inner box 12 by rotating the movable covers 14, wherein the partition board 13 can be disassembled, the sofa can also be disassembled to be used as a bed, wherein the backrest 4 can be driven relative to the base 1, the backrest 4 can be rotated by opening the buckle structure arranged between the backrest 4 and the base 1, each auxiliary supporting pad 30 is arranged on the back of the backrest 4 through a threaded shaft 29, the threaded shaft 29 is fixed through a fixing nut 34, each connecting plate 31 is arranged between the two auxiliary supporting pads 30, wherein the connection plate 31 and the auxiliary supporting pad 30 are fixed by inserting the first insertion shaft 32, the unfolded backrest 4 and the seat cushion 3 can be used as a bed.

Because a plurality of inflatable second inflatable air bags 15 are arranged around the base 1, if too much water is accumulated indoors and the user cannot walk, the sofa can be used as a lifesaving tool to spread the seat cushion 3, the second inflatable air bags 15 provide enough buoyancy, and the user can stay on the sofa to wait for rescue.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
