Automatic Built-in Air Nozzle

Abstract

An automatic air nozzle includes a valve adapted to engage with a peripheral side face defining an air path inside an inflatable object. A cam has a radial edge connected to the valve and an axial axis connected to a motor so as to drive the valve to move linearly relative to the inflatable object to open/close the air path automatically.

1 . An automatic air nozzle for an inflatable object having an air path formed in the inflatable object, the automatic air nozzle comprising:
 a valve adapted to engage with a peripheral side face defining the air path;   a cam having a radial edge adjacent to the valve; and   a motor adapted to be embedded inside the inflatable object and connected to the cam so as to drive the valve to move relative to the inflatable object to open/close the air path automatically.   
   
   
       2 . The automatic air nozzle as claimed in  claim 1 , wherein
 the cam further has
 an axial rod connected to the motor; and 
 a protrudent head protruding from the radial edge of the cam; 
   a connection seat is formed on a top of the valve;   a connection block formed on a top of the connection seat and selectively abuts the radial edge and the protrudent head of the cam; and   a recoil spring mounted around the connection seat to maintain the air path closed via the valve such that activation of the motor and the engagement of the protrudent head with the connection block is able to force the valve away from the periphery defining the air path to allow air to flow into/away from the inflatable object.   
   
   
       3 . The automatic air nozzle as claimed in  claim 1 , wherein the valve is moved linearly via the motor. 
   
   
       4 . The automatic air nozzle as claimed in  claim 1 , wherein the inflatable object is integrated with a pump casing 
   
   
       5 . An automatic air nozzle for an inflatable product having an inflatable object integrated in the inflatable product;
 wherein the inflatable object having an air path formed therein, the automatic air nozzle comprising:   a valve adapted to engage with a peripheral side face defining the air path;   a cam having a radial edge adjacent to the valve; and   a motor adapted to be embedded inside the inflatable object and connected to the cam so as to drive the valve to move relative to the inflatable object to open/close the air path automatically.
