Problems solved by technology

[0002] The Chinese patent with the document number CN2386679Y discloses an inflatable and pumpable airbag skeleton umbrella, the main purpose of which is to solve the problem that when the inflatable umbrella is rolled up after use, a small amount of air remains in the airbag skeleton, which increases the difficulty of winding.
In this scheme, the lower end of the air storage bag at the lower end is connected to the intake valve and the exhaust valve, and the composite air control head is provided with a pressure relief valve composed of elastic sheet, rubber sheet, mouth cover, valve core, etc.; The air outlet and the rubber sleeve set outside the air outlet constitute a one-way valve, which cooperates with the intake valve at the lower end of the air storage bag. When the air storage bag is pulled down, the pressure in the air storage bag decreases, and the intake valve opens (the exhaust valve closes). ), the air enters the air storage bag, when the air storage bag is pushed upward, the air is discharged from the air outlet into the composite air control head; when the inflatable umbrella is used, the exhaust valve is opened (the intake valve is closed), and the air storage bag is pushed upward, the air storage bag The air is discharged from the exhaust valve, but when the air storage bag is pulled down, the one-way valve formed by the air outlet on the valve core and the rubber sleeve set outside the air outlet cannot be conducted from the composite air control head to the air storage bag. , that is: the pressure relief device in the composite air control head cannot realize the exhaust function when the pressure in the airbag frame does not exceed the limit
Those skilled in the art should know that when it is necessary to achieve multiple inflation or pumping, two one-way valves with opposite conduction directions are required to achieve it. The solutions in the above patent documents cannot achieve the technical problems to be solved. Those skilled in the art also can't realize its scheme according to the record of its description
