  • Tire valve assembly
    Patent number: 11345196
    Abstract: A tire valve assembly is disclosed. The tire valve assembly includes a gas nozzle structure, a movable rod, an air pipe, an elastic close contact pad, a screw nut, an elastic O-ring and a dust cap. The tire valve assembly can use a punched hole on the end of the movable rod to receive the tire repair liquid flowing into the air pipe. Take out the movable rod during maintenance to remove the tire repair liquid in the punched hole. When the movable rod is reinstalled in the air pipe, the tire repair liquid remaining on the inner wall of the air pipe will also be squeezed out of the air pipe. With this, the tire repair liquid will no longer block the tire valve assembly.
