Abstract
An automatic air nozzle includes a valve adapted to engage with a peripheral side face defining the air path inside the inflatable object. A linking element has a first end operably connected to the valve and a second end. A motor is operably connected to the second end of the linking element so as to drive the valve to move linearly relative to the inflatable object to open/close the air path automatically.

An automatic air nozzle for an inflatable object having therein an air path, the automatic air nozzle comprising:
- a valve adapted to engage with a peripheral side face defining the air path;
- a linking element having a first end operably connected to the valve and a second end and comprising
- a worm shaft having a longitudinal axis;
- and
- a worm gear rotatable about a gear axis perpendicular to the longitudinal axis of the worm shaft, with the worm gear having multiple teeth formed on an outer periphery of the worm gear and engaging the worm shaft;
- and
- a motor adapted to be embedded inside the inflatable object and operably connected to the second end of the linking element so as to drive the worm shaft to rotate and drive the worm gear to rotate and in turn to drive the valve to move along an axis perpendicular to the longitudinal axis of the worm shaft relative to the inflatable object to open/close the air path automatically.
