Structure of automatic pressure adjustable air bed

Abstract

An improved structure of automatic pressure adjustable air bed mainly includes an air mattress, an air pump, and air pipes arranged therebetween, as well as a control system disposed on the air bed. The control system includes multiple pressure sensors disposed on the air mattress for acquiring pressure signals, and a main control unit for controlling actions of the air pump or electrical controlled valves thereon, thereby achieving the automatic adjustment of firmness of the air mattress.

1 . An improved structure of automatic pressure adjustable air bed, mainly comprising an air mattress, an air pump, and air pipes arranged therebetween, as well as a control system disposed on the air bed, the control system at least comprising multiple pressure sensors, a main control unit, an air pump, and multiple electrical controlled valves; wherein:
 the pressure sensors are respectively disposed on several air inflation areas of the air mattress, for sensing air pressures of corresponding areas;   the main control unit is electrically connected to the pressure sensors, the air pump, and the multiple electrical controlled valves, for receiving signals transmitted from the pressure sensors, and then outputting corresponding control signals to the corresponding air PUMP and electrical controlled valves;   the air pump is an air-charging device for the air mattress, and receives the control signals of the main control unit to implement an action of activating or shutting down;   the multiple electrical controlled valves are disposed between an air inlet port of the air pump and the air pipes for transmitting air, at least have air exhaust and locking functions, and receive the control signals of the main control unit to implement an action of activating or shutting down.   
     
     
         2 . The improved structure of automatic pressure adjustable air bed according to  claim 1 , wherein the electrical controlled valves are three stage valves having air-charging, air exhaust, and locking functions.
