A support 12 is arranged in the valve seat 1, and the valve core is fixed on the support 12. The lower part of the valve seat 1 is provided with a step surface 13, the step surface 13 is formed by the depression of the lower wall surface of the valve seat 1, and a certain space is formed between the step surface 13 and the bottom plate 5. The valve core comprises a lifting mechanism and an elastic sealing sheet 4, the elastic sealing sheet 4 is connected with the lifting mechanism through a press button 41, and the lifting mechanism can drive the elastic sealing sheet 4 to move up and down in a space between the step surface 13 and the bottom plate 5. The elastic sealing piece 4 has elasticity, can deform when stressed, and can recover after the force is removed.

As shown in fig. 2, the working principle of the inflation valve is as follows:

when the inflation valve is in an inflation state, the lifting mechanism of the valve core enables the elastic sealing sheet 4 to move upwards, the top surface of the elastic sealing sheet 4 is abutted against the step surface 13, at the moment, air is introduced from the upper part of the inflation valve, the elastic sealing sheet 4 can be bent and deformed downwards by air, the air passage of the valve seat 1 is opened, and the air can enter the interior of an inflation article from the air vent valve of the bottom plate 5 to complete inflation operation. And the gas in the inflatable article flows upwards, the elastic sealing sheet 4 and the step surface 13 abut against each other and cannot deform, the elastic sealing sheet 4 seals the gas passage of the valve seat 1, the gas in the inflatable article cannot leak out, and the one-way gas inlet in the inflating direction is realized. Prevent the air leakage of the inflatable articles in the inflation process, improve the inflation speed and improve the inflation effect.

When the inflation valve is in the gassing state, the elevating system of case makes elastic sealing piece 4 remove downwards, and the bottom surface and the bottom plate 5 of elastic sealing piece 4 offset, ventilate from the inflation valve top this moment, and elastic sealing piece 4 supports unable deformation with bottom plate 5, and elastic sealing piece 4 seals air vent 51 on the bottom plate 5, and inside the unable entering of gas supplies is inflated. And the gas in the inflatable article flows upwards, the gas can make the elastic sealing sheet 4 bend upwards and deform, the vent hole 51 is opened, and the gas in the inflatable article can be discharged from the gas channel of the valve seat 1, so that the deflation operation is completed. Realizes the unidirectional air outlet in the air outlet direction, and solves the problems that the air of the inflatable article is slowly discharged and can not be completely discharged in the air outlet process.

As shown in fig. 3 and 4, the valve seat 1 is hollow to form a gas passage, and the diameter of the opening below the step surface 13 is larger than that of the opening above the step surface 13.
