Description

Technical Field

[0001] This utility model relates to the field of inflatable sealing valves, and in particular to an integrated inflatable and deflation valve. Background Technology

[0002] Inflatable mats and bags require an air valve to prevent air leakage during use and to allow for rapid deflation when needed. For example, the applicant has developed a compression bag with an inflatable headrest function, suitable for outdoor camping. It serves as both a storage bag and a headrest when inflated. The headrest must not leak or collapse during use, affecting its effectiveness, but it also needs to be quickly deflated after use. To address this, the applicant has developed an integrated inflation / deflation valve. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides an integrated inflation and deflation valve. Tightening the valve cover allows for inflation but not deflation. After inflation, it provides a good seal and prevents slow leakage. Unscrewing the valve cover allows for rapid deflation.

[0004] To achieve the above objectives, the present invention provides the following technical solution: The integrated inflation / deflation valve includes a valve seat, a valve cover, and a valve core. The valve seat has a cylindrical vent with external threads. The valve cover has internal threads on its inner wall for screwing onto the vent of the valve seat. The top wall of the valve cover is recessed downward to form a mounting platform for the valve core. The mounting platform has a central hole and inflation holes on its surrounding surfaces. The valve core includes a core post with a core disc connected to its bottom. The core post passes through the central hole and its top end seals the central hole. The core disc deforms under force and rests against the bottom surface of the mounting platform to seal the inflation holes.

[0005] A further improvement is that the valve core is made of silicone.

[0006] A further improvement is that the top of the core post is frustoconical, and the lower part is cylindrical.

[0007] A further improvement is that the surface of the mounting platform is an upwardly concave arc surface. Alternatively, the surface of the mounting platform can be flat, with a raised ring around the outer perimeter of the inflation hole. The mounting platform surface applies a reverse deformation force to the silicone valve core, causing the core disc to deform tightly against it, effectively preventing the risk of slow leakage.

[0008] A further improvement is to provide a boss on the upper surface around the center hole of the mounting platform. This facilitates the sealing installation of the core column.

[0009] A further improvement is to provide a sealing ring on the top inner wall between the valve cover's peripheral wall and the inner peripheral wall formed by the recessed mounting platform. This provides a better seal.

[0010] A further improvement is that the outer surface of the valve cover's peripheral wall is provided with raised ridges to enhance friction, facilitating the screwing on and unscrewing of the valve cover.

[0011] A further improvement is that the outer peripheral wall of the cylindrical exhaust port of the valve seat is provided with an outer ring platform for hand gripping. The two opposite sides of the outer ring platform are straight, and the two opposite sides at the front and back are curved. This facilitates the screwing on and removal of the valve cover by hand, and the curved edges are more comfortable to hold without chafing.

[0012] A further improvement is that the bottom connector of the valve seat is diamond-shaped, with rounded edges at the front and rear corners. This facilitates welding the valve seat to the side of the bag body. Beneficial effects

[0013] This utility model features a valve core that deforms to tightly seal the inflation hole. When the valve cover is tightened, air is blown inward during inflation. The valve core is disengaged by force around its perimeter, opening the air intake channel. It can only inflate and cannot evacuate, thus eliminating the risk of slow leakage during use. When air needs to be released after use, simply unscrew the valve cover to release air quickly. Attached Figure Description

Detailed Implementation

[0015] like Figures 1 to 4 As shown, this utility model includes a valve seat 1, a valve cover 2, and a valve core 3. The valve seat 1 includes a cylindrical exhaust port 11 with external threads. The valve cover 2 has internal threads on its inner wall for screwing onto the exhaust port of the valve seat 1. The top wall of the valve cover 2 is recessed downward to form a mounting platform 21 for the valve core. The mounting platform 21 has a central hole 22 and inflation holes 23 on its surrounding surfaces. A boss 24 is provided on the upper surface around the central hole. The valve core 3 is made of silicone material and includes a core post 31 with a core disk 32 connected to its bottom. The top of the core post 31 is frustoconical, and the lower part is cylindrical. The core post 31 is inserted into the central hole 22 and its top end is sealed on the central hole of the boss 24. The bottom surface of the mounting platform 21 is an upwardly recessed arc surface. The core disk 32 deforms under force and abuts against the bottom surface of the mounting platform 21 to seal the inflation holes 23.

[0016] A sealing ring 25 is provided on the top inner wall between the two peripheral walls of the valve cover and the inner peripheral wall formed by the recessed mounting platform.

[0017] The outer surface of the valve cover 2 is provided with ridges 26 to enhance friction.

[0018] The outer peripheral wall of the cylindrical exhaust port of the valve seat 1 is provided with an outer ring platform 12 for hand holding. The two opposite sides of the outer ring platform 12 are straight sides, and the two opposite sides of the front and rear are arc sides.

[0019] The bottom connector 13 of the valve seat 1 is diamond-shaped, with arc-shaped transitions at the front and rear corners.

[0020] Under normal conditions, the core plate deforms under force and fits tightly against the surface of the mounting platform to seal the air inlet. When air is inflated, the core plate is subjected to a downward blowing force, and the four sides of the core plate deform inward to release the air inlet channel. Therefore, when the valve cover is tightened, air can only be inflated and cannot be drawn out, and there is no risk of slow leakage. When air needs to be vented, the valve cover is unscrewed to quickly vent the air from the vent.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
