[0033] Embodiment 2:

[0034] Please refer to Figure 1 , 3 -6, a fiber-supported inflatable cushion, further comprising a built-in air pump 6 and a deflation mechanism 7, wherein the built-in air pump 6 and the deflation mechanism 7 are both arranged on the edge 3 and connected to the inflation chamber 5. It can be known that an opening matching the built-in air pump 6 and the deflation mechanism 7 is arranged on the edge 3 to facilitate fixing the built-in air pump 6 and the deflation mechanism 7 on the edge 3.

[0035] Optionally, the positions of the built-in air pump 6 and the deflation mechanism 7 can be changed according to different production methods; at the same time, the built-in air pump 6 and the deflation mechanism 7 may include an air pressure adjustment function. For ease of use, the air pressure of the built-in air pump 6 and the deflation mechanism 7 can be easily adjusted during use, thereby being able to more conveniently change the overall hardness of the inflatable cushion during use so that it is suitable for people of different ages.

[0036] In this embodiment, the built-in air pump 6 is preferably an integrated air pump for inflation and suction produced and sold by Jiangsu Guorun Electric Co., Ltd. (publication number CN219691795U), which can automatically inflate and deflate the fiber-supported inflatable cushion.

[0037] In this embodiment, the deflation mechanism 7 can assist the built-in air pump 6 in deflation, thereby increasing the deflation speed of the fiber-supported inflatable cushion.

[0038] Specifically, the deflation mechanism 7 includes a valve body 701, a valve stem 702, a reset member 703, a first sealing member 704 and a second sealing member 705. The valve body 701 is a hollow structure with openings at both ends. The two openings of the valve body 701 are respectively a first opening 7011 and a second opening 7012. The valve body 701 is heat-sealed and fixedly arranged on the edge 3. The valve stem 702 is a multi-section structure with different diameters of each section. The valve stem 702 is arranged in the valve body 701 and can move along the axis of the valve body 701. The outer wall of the valve stem 702 is provided with a first mounting groove 7021 and a second mounting groove 7022. The first and second sealing members 704 and 705 are respectively arranged in the first mounting groove 7021 and the second mounting groove 7022 to seal the two openings (the first opening 7011 and the second opening 7012) of the valve body 701 to prevent the fiber-supported inflatable cushion from leaking. The design of the double sealing members increases the anti-leakage capability. By pressing the valve stem 702, the double sealing members leave the double openings, opening the openings, and then deflate the fiber-supported inflatable cushion.

[0039] In this embodiment, preferably, the reset member 703 is a spring, and the first sealing member 704 and the second sealing member 705 are O-shaped rubber rings.

[0040] Furthermore, four gas flow channels 7023 are provided on the outer wall of the valve stem 702, and the gas flow channels 7023 are evenly arranged on the valve stem 702. The design of the four gas flow channels 7023 increases the gas flow surface, which can accelerate the release of gas, and in the normal state (not deflated), the gas flow channels 7023 will be located in the second opening 7012 and the valve body 701, ensuring air tightness.

[0041] Furthermore, the valve stem 702 is provided with an outer ring 7026 near the first mounting groove 7021, and ten air holes 7027 distributed at equal intervals are opened on the outer ring 7026. The design of ten air holes 7027 increases the gas flow surface and can accelerate the release of gas. The number of air holes 7027 can be changed according to the speed of deflation.

[0042] Furthermore, a guide groove 7028 is provided on the outer ring 7026, and a guide rib 7014 is provided on the inner wall of the valve body 701. The guide rib 7014 and the valve body 701 are an integrated structure. The guide rib 7014 and the guide groove 7028 are adapted to play a guiding role, so that when the valve stem 702 is pressed, the center of the valve stem 702 is ensured not to be offset.

[0043] Furthermore, a groove 7024 is provided on the valve stem 702, and a connecting portion 7013 is provided on the inner wall of the valve body 701, and the connecting portion 7013 and the groove 7024 are on the same side. The deflation mechanism 7 also includes a connecting rod 706, and the connecting rod 706 is a heart-shaped structure. When the valve stem 702 is pressed, one end of the connecting rod 706 is movably hinged to the connecting portion 7013, and the other end is located in the groove 7024. Since the groove 7024 is a special heart-shaped structure, one end of the connecting rod 706 will rotate around the hinge point, and the other end will move in the groove 7024.

[0044] When the air is not deflated, the other end of the connecting rod 706 is located at point A of the groove 7024; when the air is deflated, the valve stem 702 is pressed, the reset member 703 is compressed, the sealing member leaves the opening, and the connecting rod 706 moves in the groove 7024. When the other end of the connecting rod 706 moves to point B of the groove 7024, the external force on the valve stem 702 is removed, and the valve stem 702 is stuck here, that is, the connecting rod 706 fixes the valve stem 702. At this time, the user does not need to press the valve stem 702 all the time, and the two openings can be opened to ensure normal deflation, freeing up labor; when the deflation is completed, the valve stem 702 is pressed again, and the other end of the connecting rod 706 returns to point A from point B of the groove 7024, and the external force on the valve stem 702 is removed. The valve stem 702 is reset under the action of the reset member 703, and the double sealing members re-block the double openings.

[0045] Furthermore, a pressing head 7025 is provided at one end of the valve stem 702, and the pressing head 7025 passes through the first opening 7011 of the valve body 701. The pressing head 7025 is a truncated cone structure, and the diameter of the pressing head 7025 at one end close to the outer ring 7026 is larger than that at the other end. When the pressing head 7025 is gradually pressed into the valve body 701, the gap between the pressing head 7025 and the opening will become larger and larger, which facilitates the rapid release of the gas inside the fiber-supported inflatable cushion and increases the deflation speed of the fiber-supported inflatable cushion.

[0046] Furthermore, the venting mechanism 7 also includes a plug 707, which can seal the valve body 701. An internal thread is provided on the inner wall of the plug 707, and an external thread is provided on the outer wall of the valve body 701. The external thread on the valve body 701 is used in conjunction with the internal thread on the plug 707, that is, the plug 707 is connected to the valve body 701 through a threaded structure.

[0047] When the deflation mechanism of the utility model deflates, the flow route of the gas in the deflation mechanism 7 is: inflation cavity 5 - second opening 7012 - gas flow channel 7023 - inner cavity of valve body 701 - air hole 7027 - first opening 7011 - outside.
