Mattress adjusting system

Abstract

A mattress adjusting system includes at least two airbag sets disposed in the mattress which overlap to each other, at least one air pump for supplying air to a main air tube, each airbag set being connected with the main air tube via a branch air tube, and a control valve disposed in each branch air tube for turning on/off the branch air tube, said air pump and control valves are manipulated by at least one controller. Each airbag set is inflated so as to support the mattress, or the airbag set could be alternatively deflated and inflated to provide a massage effect. When the two airbag sets overlapping to each other are alternatively deflated and inflated, the raised surface of the mattress could appear to shift smoothly.

1 . An adjusting system for mattresses, wherein each mattress is provided at least with two airbag sets lapping one over other, and in said mattress adjusting system, there is at least an aerating pump for providing air for a main air tube, each of said airbag sets is connected with said main air tube via a branch air tube which is provided with a control valve for opening/closing said branch air tube, operation of said aerating pump and said control valve is controlled at least by a controller; said branch air tubes are communicated with one another, inflated airbag sets release air and inject it into other airbag sets according to a pressure balancing principle. 
   
   
       2 . The adjusting system for mattresses as in  claim 1 , said system is characterized in that: said main air tube is provided with a safe pressure releasing valve. 
   
   
       3 . The adjusting system for mattresses as in  claim 1 , said system is characterized in that: said main air tube is provided with a pressure detecting unit. 
   
   
       4 . The adjusting system for mattresses as in  claim 1 , said system is characterized in that: said branch air tube is provided with a pressure detecting unit. 
   
   
       5 . The adjusting system for mattresses as in  claim 1 , said system is characterized in that: said main air tube is provided with a tap air tube, said branch air tubes of said airbag sets lapped are parallelly connected to same tap air tube. 
   
   
       6 . The adjusting system for mattresses as in  claim 5 , said system is characterized in that: said control valve has an air discharging passage for air discharging of a corresponding one of said airbag sets. 
   
   
       7 . The adjusting system for mattresses as in  claim 1 , said system is characterized in that: a tap valve is provided between said tap air tube and said main air tube. 
   
   
       8 . The adjusting system for mattresses as in  claim 1 , said system is characterized in that: said branch air tubes of said airbag sets lapping one over other are parallelly connected to said main air tube. 
   
   
       9 . The adjusting system for mattresses as in  claim 8 , said system is characterized in that: said main air tube is provided with an air exhaust valve. 
   
   
       10 . The adjusting system for mattresses as in  claim 8 , said system is characterized in that: said control valve has an air discharging passage for air discharging of a corresponding one of said airbag sets.
