Air mattress system

Abstract

An air mattress system includes an inflatable mattress comprised of isolated cells that are filled with air of different pressures and a pumping device including an air pump controlled by a remote control pedant that is electrically coupled to the pump by a cable. The pumping device has an air inlet with an air filter arranged therein for drawing surrounding air into the pump and an air outlet through which pressurized air is supplied from the pump to a hose assembly that is connected to the cells for inflating the cells. The remote control pedant is removably received in a recess defined in a casing of the pumping device to selectively serve as a remote control or a fixed control panel for the pumping device. Control buttons and indicators are provided on the remote control pedant. A quick release valve is provided on the mattress to release air from the cells and thus deflating the mattress in a short period of time.

1 . An air mattress system comprising: 
 an inflatable mattress comprising a plurality of cells that are isolated from each other and are filled with air of different pressures, each cell having an air passage, the mattress further comprising a quick release valve that is operable to release air from at least some of the cells in a short period for deflating the cells;    a pumping device comprising: 
 a casing adapted to encase an air pump, the casing having a surface defining a recess,  
 a control unit removably received in the recess and in electrical connection with the pump for controlling the pump,  
 an air inlet port in fluid communication with the pump, through which surrounding air is drawn into the casing by the pump, and  
 an air outlet port in fluid communication with the pump, through which air is pumped out of the casing by the pump; and  
   a hose assembly connecting the air outlet port to the air passages of the cells to supply air to the cells.    
   
   
       2 . The air mattress system as claimed in  claim 1  further comprising an air filter arranged in the air inlet port of the casing.  
   
   
       3 . The air mattress system as claimed in  claim 1  further comprising a built-in power source that powers the pump and the control unit.  
   
   
       4 . The air mattress system as claimed in  claim 3 , wherein the built-in power source comprises a battery pack removably mounted in the casing.  
   
   
       5 . The air mattress system as claimed in  claim 4 , wherein the battery pack comprises rechargeable battery.  
   
   
       6 . The air mattress system as claimed in  claim 1 , wherein the casing comprises an external power connection adapted to selectively connect to an external power source.  
   
   
       7 . The air mattress system as claimed in  claim 6  further comprising a built-in power source.  
   
   
       8 . The air mattress system as claimed in  claim 7 , wherein the built-in power source comprises a rechargeable battery pack that is selectively charged by the external power source.  
   
   
       9 . The air mattress system as claimed in  claim 1 , wherein the control unit comprises at least one hook releasably engageable with an opening defined in a bottom of the recess of the casing to retain the control unit in the recess.  
   
   
       10 . The air mattress system as claimed in  claim 9 , wherein the hook comprises an L-shaped member.  
   
   
       11 . The air mattress system as claimed in  claim 6  further comprising a power switch.  
   
   
       12 . The air mattress system as claimed in  claim 1 , wherein the isolated cells are arranged in a line in longitudinal direction, each cell being elongated in transverse direction.
