Referring to
The present invention has a wide range of applications and can be used indoors or outdoors. For example, the compressed sponge self-inflating cushion can be used as a cushion for children at home, or can be used as a cushion in large fences outdoors, or can be used by being laid on the lawn. Under the elastic force of the high-resilience sponge 2, the sponge 2 automatically absorbs air, that is, the inflatable cushion body can be automatically inflated through the inflation and deflation assembly 4. The inflation and deflation assembly 4 is closed after inflation is completed. After use, the inflation and deflation assembly 4 is opened, then the inflatable cushion body is pressed to exhaust air in the sponge 2, and then the inflation and deflation assembly 4 is closed. The operation is convenient, besides, there is no complicated electronic circuit inside, so that there is no need to worry about whether the inflatable cushion body cannot be inflated due to electric leakage or insufficient power supply. Moreover, in the present application, the surface of the sponge 2 is provided with a plurality of parallel folding grooves 21 for convenient folding and winding, so the user can conveniently wind up the inflatable cushion body. Meanwhile, the edge of the back of the air cushion bag 1 is provided with the first connecting part 31, and the back of the air cushion bag 1 is provided with the second connecting part 32 assembled with the first connecting part 31, wherein the inflatable cushion body is winded, the connecting part 31 is connected to the second connecting part 32, and the inflatable cushion body is kept in a winded state, so that the floor area of the inflatable cushion body is reduced, and the inflatable cushion body is convenient to carry; meanwhile, deflation of air in the sponge 2 can be accelerated through the cooperation of the first connecting part 31 and the second connecting part 32, and the volume of the inflatable cushion body is further reduced.
Further, the inflation and deflation assembly 4 includes a mounting base 41 which is assembled on the air cushion bag 1 and communicates with the inside of the air cushion bag 1, a one-way valve 42 which is assembled on the mounting base 41 and controls air to flow into the air cushion bag 1 from the outside of the air cushion bag 1 only, and a sealing plug 43 assembled on the surface of the one-way valve 42 and used for preventing air from flowing into the air cushion bag 1 from the outside of the air cushion bag 1.
Wherein in the specific embodiment, inflation or deflation is achieved by the inflation and deflation assembly 4. When inflation is required, only the sealing plug 43 needs to be opened, since the sponge 2 is high in resilience, the sponge 2 will absorb air, so that outside air passes through the one-way valve 42, enters the mounting base 41, finally passes through the mounting base 41 and enters the air cushion bag 1 to achieve inflation, and during the inflation process, even if the air inside the sponge 2 is compressed, the air will not escape out of the air cushion bag 1 due to the existence of the one-way valve 42; and when deflation is required, only the one-way valve 42 needs to be removed from the mounting base 41, since there is no hindrance by the one-way valve 42 at this time, deflation can be achieved directly by compressing the sponge 2 inside.
Further, the one-way valve 42 includes a valve body and a one-way valve flap 425, wherein the valve body is provided with a valve groove in a recessed mode, the bottom of the valve groove is provided with a plurality of communication holes 424 and a first mounting hole 426 used for mounting the one-way valve flap 425, the umbrella-shaped one-way valve flap 425 is mounted in the first mounting hole 426 and controls the communication holes 424 to be connected or disconnected with the mounting base 41, and the sealing plug 43 is arranged in the valve groove in a sealed mode and isolates the communication holes 424 from the outside air. The one-way valve flap 425 includes a first umbrella post which is inserted in the first mounting hole 426 and slides along the first mounting hole 426, a first blocking disc extending circumferentially along one end of the first umbrella post, and a first plug annularly arranged on the first umbrella post to be clamped on the inner wall of the first mounting hole 426. In the specific embodiment, during the inflation process, the one-way valve flap 425 is sucked down under the action of the sponge 2, so that the first blocking disc no longer blocks the communication holes 424, and the first plug can prevent the first umbrella post from moving down.
Further, the inflation and deflation assembly 4 further includes a first connecting belt 411, wherein one end of the first connecting belt 411 is connected to one side of the mounting base 41, and the other end of the first connecting belt 411 is connected to one side of the valve body. Further, the inflation and deflation assembly 4 further includes a second connecting belt 412, wherein one end of the second connecting belt 412 is connected to one side of the valve body, and the other end of the second connecting belt 412 is connected to one side of the sealing plug 43. In the specific embodiment, in order to facilitate the assembling between the mounting base 41, the valve body and the sealing plug 43, the first connecting belt 411 and the second connecting belt 412 are adopted for connection, so that the situation that inflation or deflation can not be conducted due to part scattering is avoided.
Further, the top of the valve body is provided with a first receding notch 421 and a second receding notch 422, and the part, connected with the sealing plug 43, of the second connecting belt 412 is clamped in the first receding notch 421, a third connecting belt 413 is further connected to a side surface of the sealing plug 43, and the third connecting belt 413 is clamped in the second receding notch 422. Wherein the first receding notch 421 is formed in order to position the second connecting belt 412, the second receding notch 422 is further provided for fixing the third connecting belt 413, and the third connecting belt 413 is provided for facilitating the opening of the sealing plug 43.
Further, a positioning post 423 is arranged at the second receding notch 422, the third connecting belt 413 is provided with a positioning hole 4131, and the positioning post 423 is inserted in the positioning hole 4131. The third connecting belt 413 being firmly assembled in the second receding notch 422 can be ensured by the cooperation between the positioning post 423 and the positioning hole 4131.
Further, the first connecting part 31 is a hook fastener, and the second connecting part 32 is a loop fastener. After the inflatable cushion body is compressed and winded, the hook fastener and the loop fastener cooperate to wind up the inflatable cushion body, so as to prevent the cushion from unfolding.
Further, in order to ensure the winding stability and increase the deflation speed of the self-inflating cushion, a binding device is further arranged at the edge of the air cushion bag 1 of the present application, and the binding device includes a binding buckle 33 provided with a clamping pin 331 and a binding belt 34 with positioning holes 341 formed in the surface, wherein the binding buckle 33 is connected to the edge of the air cushion bag 1, one end of the binding belt 34 is hinged to one end of the binding buckle 33, the other end of the binding belt 34 is winded around the inflatable cushion body in a winded state and penetrates through the binding buckle 33, and the clamping pin 331 penetrates through the positioning holes 341 for positioning. Wherein the working principle of the binding device is similar to that of a watchband, and tightening the inflatable cushion body by the binding belt 34 can speed up the deflation of the inside sponge 2; when the deflation is completed, the binding belt 34 penetrates through the binding buckle 33 and the clamping pin 331 penetrates through the positioning holes 341 for positioning.
The above embodiments are only description of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made by ordinary engineers in the art to the technical solution of the present invention should fall within the protection scope determined by the claims of the present invention.
