[0062] The gas filling and discharging part is provided with a gas nozzle which can automatically adjust the airflow;

[0063] The main body is filled with high-elastic sponge or high-rebound sponge; the main body can be a rectangular or square flat plate structure;

[0064] The inflation and deflation part is sealed and connected to the main body;

[0065] A structure is formed in which when the air nozzle capable of automatically regulating the airflow is closed, the main body portion filled with the highly elastic sponge maintains the current status quo, and when the air nozzle capable of automatically regulating the airflow is turned on or continuously turned on, the main body portion filled with the highly elastic sponge automatically pops open and returns to a natural original state.

[0066] The ratio of the thickness of the high-elastic sponge (or high-rebound sponge) filled in the main body to its surface area is 1:86 or 1:135, that is, if the unit of thickness is 1, the unit of the surface area of ​​the main body (here mainly refers to the surface area of ​​one side of the rectangle or square) is 86 times or 135 times the thickness.

[0067] The gas nozzle comprises a knob 001, a center bracket 002, a gas valve outer sleeve 003, a gas valve inner column 004 and a gas valve shaft pin 005;

[0068] The air valve housing 003 is pressed into the through hole provided on the central support 002 along the outer diameter;

[0069] The air valve inner column 004 passes through the inner hole of the air valve outer sleeve 003 and is locked and connected with the knob 001;

[0070] The valve shaft pin 005 rivets the valve inner column 004 and the valve outer sleeve 003 into an integral structure;

[0071] A structure is formed in which when the knob 001 is rotated, the air valve inner column 004 moves linearly up and down (or linearly reciprocates) along the central axis of the inner hole of the air valve outer sleeve 003 under the control of the air valve shaft pin 005.

[0072] like Figure 4a , Figure 4b , Figure 4c and Figure 4d As shown, the knob 001 is a truncated cone structure as a whole, and a first countersunk hole is arranged inwardly along the bottom surface of the cone, and the first countersunk hole has at least one pair of annular protrusions and at least one pair of annular recesses symmetrically arranged along the inner wall; the at least one pair of annular recesses are located at the opening position of the first countersunk hole; a pair of symmetrically arranged or arc-shaped first grooves are arranged along the top surface (top surface) of the cone, and the annular first grooves are connected or in a connected state with the first countersunk hole.

[0073] like Figure 5a , Figure 5b , Figure 5c and Figure 5d As shown, the main body of the center bracket 002 is a cylindrical structure, and symmetrical wings (wings arranged in a symmetrical state) are integrally extended and gradually extended to both sides along the two outer side walls of the cylinder; the head of the wing is flat, the root gradually thickens and is smoothly connected to the outer side wall of the cylinder; that is, when viewed along the cylindrical surface of the center bracket 002, the center bracket 002 is shaped like a date pit with pointed ends and a wide middle. If viewed along the cylindrical side of the center bracket 002, the appearance of the center bracket 002 is a rectangle.

[0075] like Figure 6a , Figure 6b , Figure 6c and Figure 6d As shown, the valve housing 003 is an upright tube structure as a whole, the outer diameter of the tube structure is sloped and a plurality of dovetail-shaped protrusions are arranged along the outer diameter; the outer diameter of the tube structure is provided with a pin hole that can be penetrated and used to rivet the valve shaft pin 005;

[0076] The tube structure is provided with a stepped second groove (used to accommodate a sealing ring or a spring sealing ring) along the inner diameter opening at one end, and an annular concave platform is provided along the outer diameter opening at the other end; the concave platform is inserted into the second through hole of the valve housing 003;

[0077] A pair of slideways are symmetrically arranged on the inner diameter of the tube structure (the pair of slideways are axially arranged on the inner diameter surface of the tube structure, and the valve inner column 004 slides into the pair of slideways through a pair of dovetail protrusions arranged thereon and is further inserted into the valve outer sleeve 003 and fixed). The pair of slideways and the pair of pin holes are arranged in a cross position, that is, the connecting line of the pair of pin holes is perpendicular to the axis and is in a vertical cross state with the connecting line of the pair of slideways. The so-called cross means that the two intersecting lines must have intersections with the central axis respectively.

[0078] like Figure 7a , Figure 7b , Figure 7c , Figure 7d , Figure 7e , Figure 7f and Figure 7g As shown, the valve inner column 004 is an upright circular tube structure as a whole, and the circular tube structure includes a straight tube part and a bottom end connected as one body; the bottom end of the circular tube structure is closed and has an outer diameter greater than the outer diameter of the straight tube part, and the bottom end is provided with a ring groove for placing a sealing ring or a spring sealing ring;

[0079] The straight pipe part is provided with a pair of annular (or arc-shaped) third through holes, a pair of zigzag fourth through holes and a pair of dovetail-shaped protrusions (the dovetail-shaped protrusions are annular or arc-shaped in appearance) in sequence along the outer diameter starting from the connection with the bottom end (or the connecting part), and a pair of annular convex clamping parts are provided on the top of the straight pipe part; the pair of annular third through holes are arranged in symmetrical positions with respect to each other, the pair of zigzag fourth through holes are arranged in symmetrical positions with respect to each other, the pair of dovetail-shaped protrusions are arranged in symmetrical positions with respect to each other, and the pair of annular convex clamping parts are arranged in symmetrical positions with respect to each other; the pair of zigzag fourth through holes can be used for the valve shaft pin 005 to slide along the zigzag shape.

[0080] The pair of annular third through holes and the pair of zigzag fourth through holes are located on the same or parallel horizontal lines, that is, the center line between the pair of annular third through holes and the center line between the pair of zigzag fourth through holes are parallel to each other; the pair of dovetail-shaped protrusions and the pair of annular convex clamping parts are located on the same or parallel horizontal lines, that is, the center line between the pair of dovetail-shaped protrusions and the center line between the pair of annular convex clamping parts are parallel to each other; or in other words, the pair of annular third through holes and the pair of zigzag fourth through holes are located in the same axial plane, the pair of dovetail-shaped protrusions and the pair of annular convex clamping parts are located in the same axial plane, and the two axial planes are perpendicular to each other.

[0081] The horizontal line where the pair of annular third through holes are located is in a cross state with the horizontal line where the pair of annular convex clamps are located; that is, the plane where the pair of annular third through holes are located is perpendicular to the plane where the pair of annular convex clamps (and a pair of dovetail protrusions) are located.

[0082] The valve shaft pin 005 passes horizontally through the pair of zigzag fourth through holes and rivets the valve inner column 004 and the valve outer sleeve 003 into an integral structure through the pin hole arranged on the valve outer sleeve 003.

[0083] The pair of dovetail protrusions are located near the top of the straight pipe portion; the ratio of the distance between the pair of zigzag fourth through holes and the pair of dovetail protrusions to the length of the straight pipe portion is 2:5, that is, if the length of the straight pipe portion is unit 5, then the distance between the pair of zigzag fourth through holes and the pair of dovetail protrusions is unit 2 (2 units out of 5 units).

[0084] like Figure 1a , 1b and Figure 1c The outer packaging of the main body is PVC coated fabric (watertight and airtight); when the air nozzle is rotated to open, the high-elastic sponge automatically bounces up, playing the role of air cushion suction or inflation until it is fully bounced up. When the air nozzle is rotated to close (close), the air cushion becomes a closed airbag.
