[0025] The utility model is further described below in conjunction with specific embodiments and drawings.

[0026] See Figure 1-6As shown, a waterproof and leak-proof air filling and exhaust device for an air cushion is shown, that is, when in use, the waterproof and leak-proof air filling and exhaust device is installed on the air cushion, and can inflate the air cushion and also deflate (i.e. exhaust) the air cushion.

[0027] The utility model is a waterproof and leak-proof air filling and exhaust device for an air cushion, comprising: an airbag lower cover 1, a lower air seat 2, a first air sealing cushion module 3, an airbag upper cover 4, an upper air seat 5, a second air sealing cushion module 6, an air release component 7, a sealing cover 8, and a sealing gasket 9.

[0028] The lower air seat 2 is arranged on one side of the airbag lower cover 1, and the lower air seat 2 has a through air inlet and outlet hole 21. The first air sealing cushion module 3 is arranged at the lower end of the lower air seat 2 and can block the air inlet and outlet hole 21. The upper air bag cover 4 is arranged on the upper end of the airbag lower cover 1, and is formed with an airbag chamber 10. Both the upper air bag cover 4 and the lower air bag cover 1 can be pressed to change the volume of the airbag chamber 10, thereby achieving the purpose of pumping air, and the upper air bag cover 4 and the lower air bag cover 1 can be reset by themselves after being pressed. The upper air seat 5 is arranged on one side of the airbag upper cover 4, and the upper air seat 5 has an air discharge hole 51 and an air inlet hole 52 that pass through the upper and lower ends. The upper air seat 5 is installed on the lower air seat 2, and a gap 20 connecting the airbag chamber 10 is formed therebetween. The second air sealing cushion module 6 is arranged in the gap 20 and can float up and down, and can block the air inlet hole 52. The venting assembly 7 includes a venting rod 71 inserted into the air inlet hole 52 and a spring 72 sleeved on the periphery of the venting rod 71 and pressed against the upper air seat 5. The sealing portion 711 of the venting rod 71 seals the venting hole 51 under the elastic force of the spring 72, and the upper end of the venting rod 71 is exposed in the upper air seat 5. The venting rod 71 can be pressed to push the first air sealing cushion module 3 away from the air inlet and outlet holes 21 to open the air inlet and outlet holes 21. The sealing cover 8 is detachably mounted on the upper air seat 5, and a sealing gasket 9 is also provided between the sealing cover 8 and the upper air seat 5 to achieve a sealed assembly.

[0029] The working principle of the utility model is:

[0030] Under normal conditions, the first air-sealing cushion module 3 blocks the air inlet and outlet holes 21, the second air-sealing cushion module 6 blocks the air inlet hole 52, and the sealing portion 711 of the air-release rod 71 blocks the air-release hole 51 under the elastic force of the spring 72, so that the air cushion cavity is isolated from the outside world. At the same time, the sealing cover 8 is installed on the upper air seat 5, and a sealing gasket 9 is also provided between the sealing cover 8 and the upper air seat 5, so as to achieve a sealed assembly, thereby achieving an excellent waterproof effect, and also having a better anti-leakage effect. In addition, because the sealing cover 8 covers the air-release rod 71, it can protect the air-release rod 71, thereby preventing the problem of accidental air release caused by accidental touching of the air-release rod 71.

[0031] When the air cushion needs to be inflated, first remove the sealing cover 8 relative to the upper air seat 5, and press the airbag upper cover 4. At this time, the airbag upper cover 4 and the airbag lower cover 1 will be squeezed to change the volume of the airbag chamber 10, thereby achieving the purpose of pumping air. That is, the pressure formed will push the first air cushion module 3 to open the air inlet and outlet holes 21 for a moment. At the same time, the second air cushion module 6 will be adsorbed downward to open the air inlet hole 52 for a moment, so that the inner cavity of the air cushion is connected to the outside world through the air inlet and outlet holes 21 and the air inlet hole 52, and the external gas can be pumped into the inner cavity of the air cushion through this pumping principle. Repeating this step continuously can achieve the purpose of inflating the air cushion.

[0032] When the air cushion needs to be deflated (i.e., exhausted), the deflation rod 71 is directly pressed to move the deflation rod 71 downward to push the first air sealing cushion module 3 away from the air inlet and outlet holes 21, thereby opening the air inlet and outlet holes 21. At the same time, the sealing portion 711 of the deflation rod 71 also leaves the deflation hole 51, thereby opening the air outlet hole 51, so that the inner cavity of the air cushion is connected to the outside through the deflation holes 21 and 51, thereby achieving the effect of deflation.

[0033] The first air sealing cushion module 3 includes a pressure elastic cotton cover 31 detachably mounted on the lower end of the lower air seat 2, a first elastic cotton 32 mounted in the pressure elastic cotton cover 31, and a first air sealing cushion 33 disposed on the upper end of the first elastic cotton 32. The first air sealing cushion 33 is attached to the lower end of the lower air seat 2 and blocks the air inlet and outlet holes 21 under the elastic force of the first elastic cotton 32, and the pressure elastic cotton cover 31 is provided with air holes 311. A gap is formed between the inner wall of the pressure elastic cotton cover 31 and the outside of the first elastic cotton 32. The first elastic cotton 32 has a certain elastic force, so that when the first air sealing cushion 33 is pressed down and the first elastic cotton 32 is compressed, and there is no force acting on the first air sealing cushion 33, the first elastic cotton 32 can increase the elastic force to drive the first air sealing cushion 33 to reset. After the first air sealing cushion 33 is pressed down, the air inlet and outlet holes 21 will be opened. The pressure elastic cotton cover 31 is provided with an air hole 311 so that the inner cavity of the air cushion is communicated with the air inlet and outlet holes 21 after the air inlet and outlet holes 21 are opened.

[0034] The lower end of the lower air seat 2 is also provided with a convex ring body 22, the upper ends of the first air sealing cushion 33 and the first elastic cotton 32 are both placed in the convex ring body 22, and the pressure elastic cotton cover 31 is buckled and fixed to the outside of the convex ring body 22, and its assembly structure is simple. Among them, the convex ring body 22 is provided with a buckle body 221 on the outside, and the pressure elastic cotton cover 31 is provided with a buckle hole 312, and the buckle body 221 is buckled and fixed with the buckle hole 312 to achieve stable assembly, and the buckle body 221 will not completely fill the buckle hole 312, so that the buckle hole 312 is partially used as an air hole.

[0035] The airbag upper cover 4 and the airbag lower cover 1 are both arc-shaped, so that the airbag upper cover 4 and the airbag lower cover 1 are butt-jointed and assembled to form an airbag.

[0036] The second air-sealing cushion module 6 includes a second elastic cotton 61 and a second air-sealing cushion 62 disposed on the upper end of the second elastic cotton 61. The second air-sealing cushion 62 is attached to the lower end of the upper air seat 5 and blocks the air inlet 52 under the elastic force of the second elastic cotton 61. When the airbag upper cover 4 is pressed down, the gap 10 forms a negative pressure, and the second air-sealing cushion 62 can be pressed downward, compressing the second elastic cotton 61 at the same time, thereby achieving the purpose of opening the air inlet 52. In the absence of pressure, the second elastic cotton 61 is reset to drive the second air-sealing cushion 62 to re-block the air inlet 52.

[0037] The upper end of the lower air seat 2 is also provided with a mounting groove 23 communicating with the airbag chamber 10 , and the second elastic cotton 61 is arranged in the mounting groove 23 to ensure the stability of the assembly structure.

[0038] The sealing cover 8 includes a cover body 81 and an externally threaded column 82 formed at the lower end of the cover body 81. The externally threaded column 82 is spirally fixed to the upper air seat 5. Its assembly structure is simple and easy to assemble and disassemble. It also has a sealing effect to a certain extent. The sealing gasket 9 is sleeved on the upper part of the externally threaded column 82 and contacts the cover body 81, so that the cover body 81 directly presses the sealing gasket 9 onto the upper air seat 5, thereby achieving a sealing effect. Its waterproof and air leakage-proof effects are extremely ideal.

[0039] The assembly structure of the external thread column 82 and the upper air seat 5 includes at least the following two types:

[0040] The first type is: the inner wall of the upper air seat 5 is provided with an external thread adapted to the external thread column 82;

[0041] The second type is: a nut 53 adapted to the external threaded column 82 is provided in the upper air seat 5, and the nut 53 is located beside the air inlet 52 and covers a part of the port of the air inlet 52, wherein the air inlet 52 is inclined.

[0042] In order to make the airbag upper cover 4 and the airbag lower cover 1 have good elastic deformation ability and ensure service life, the airbag upper cover 4 and the airbag lower cover 1 are generally made of elastic plastic. The upper air seat 5 is integrally formed on one side of the airbag upper cover 4, and the upper air seat 5 is also made of elastic plastic, so that the upper air seat 5 adopts the second assembly structure mentioned above, so that the nut 53 is embedded and fixed in the upper air seat 5, so that the external thread column 82 can be stably assembled with the upper air seat 5 in the later stage, that is, the sealing cover 8 can be stably installed on the upper air seat 5.

[0043] In addition, the external threaded column 82 is provided with a receiving groove 821 upwardly along its lower end, and the upper end of the deflation rod 71 is received in the receiving groove 821, thereby greatly reducing the height of the sealing cover 8, thereby making the overall height of the utility model lower to meet the use requirements.

[0044] The blocking portion 711 is in the shape of a truncated cone with a small top and a large bottom. Correspondingly, the vent hole 51 is also in the shape of a truncated cone with a small top and a large bottom. This structure enables the blocking portion 711 to be in close contact with the vent hole 51, thereby achieving a better sealing effect.

[0045] In summary, under normal conditions, the first air-sealing cushion module 3 blocks the air inlet and outlet holes 21, the second air-sealing cushion module 6 blocks the air inlet hole 52, and the sealing portion 711 of the deflation rod 71 blocks the deflation hole 51 under the elastic force of the spring 72, so that the inner cavity of the air cushion is isolated from the outside world. At the same time, the sealing cover 8 is installed on the upper air seat 5, and a sealing gasket 9 is also provided between the sealing cover 8 and the upper air seat 5, so as to achieve a sealed assembly, thereby achieving an excellent waterproof effect, and also having a better anti-leakage effect. In addition, because the sealing cover 8 covers the deflation rod 71, it can protect the deflation rod 71, thereby preventing the problem of accidental deflation caused by accidental touching of the deflation rod 71.

[0046] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
