Valve cap featuring easy inflation and sealing and production process thereof

A valve cap featuring easy inflation and sealing, comprising a cap housing, wherein a chamber axially runs through the cap housing;

• a self-sealing inflation valve is provided in the chamber, and the self-sealing inflation valve is automatically sealed in a normal state and is opened due to a pressing action of an ejector rod of an inflation chuck during inflation;
• the self-sealing inflation valve comprises a valve core rod, a reset spring, a valve core sealing gasket, and a valve core base;
• the valve core base is positioned and mounted in a middle-lower part of the chamber;
• the valve core rod is movably provided in the chamber, and a lower end of the valve core rod penetrates into an inflation channel of the valve core base;
• a circular sealing protrusion is provided in the inflation channel;
• the valve core sealing gasket is positioned and sleeved on the valve core rod;
• the valve core sealing gasket is in a seal fit with the circular sealing protrusion through a spring force in the normal state;
• the reset spring is sleeved on the valve core rod to provide a sealing pressure for the valve core sealing gasket;
• the lower end of the valve core rod is riveted to a valve core rivet joint for fixing the valve core sealing gasket;
• and an O-ring in a seal fit with a top surface of a valve is provided on an outer peripheral surface of a lower end of the valve core base,
• wherein the chamber comprises a valve stem chamber, a valve core base positioning chamber, and an internal thread chamber in sequence from top to bottom;
• the valve core base is positioned and mounted in an anti-rotation manner in the valve core base positioning chamber of the cap housing;
• the valve core rod is located in the valve stem chamber of the cap housing, and the lower end of the valve core rod extends into the valve core base positioning chamber;
• and an internal thread is provided in the internal thread chamber and is spirally fitted with the valve,
• wherein an outer peripheral surface of a middle-lower part of the cap housing is provided with an anti-slip pattern, wherein the anti-slip pattern is formed through rolling and eases manual rotation;
• and an outer peripheral surface of an upper part of the cap housing is provided with an anti-detachment tooth groove for preventing an inflation tube from detaching during inflation,
• wherein an outer peripheral surface of the valve core base is provided with a plurality of limiting teeth, wherein the plurality of limiting teeth are longitudinally and equidistantly formed to prevent the valve core base from rotating relative to the cap housing;
• and a top surface of the valve core base is provided with a raised element, wherein the raised element is sleeved inside a lower end of the reset spring in a fitted manner.
