Abstract

An active supporting device for a health bed and a method thereof is disclosed, an air spring layer is on a top surface of a mattress; the air spring layer comprises a plurality of gasbags, each of the gasbags is connected to an aerating/deflating device through an air tube set, the aerating/deflating device is connected to a control device, the control device drives the aerating/deflating device to aerate or deflate the gasbags of the air spring layer through the air tube set, each air tube of the air tube set is connected to a pressure sensor; the air spring layer is on a top surface of the mattress and covers the parts of a human being from the neck to the buttocks of the human being, initially the aerating/deflating device aerates the all gasbags and detect the pressure in each gasbag via each air tube, after each pressure approaches a preset value, the aeration is stopped, so that the aerating time period of each gasbag is obtained. Thus, the gasbags corresponding to the waist need longer time periods. After re-aeration, the gasbags corresponding to the waist are enough to actively support the waist for the best sleep.

         3 . The active supporting device for the health bed according to  claim 1 , wherein the cushion is selected from the group consisting of: foam, independent cylinder, memory foam, flexible material. 
     
     
         4 . The active supporting device for the health bed according to  claim 2 , wherein the top surface of the cushion of the mattress is covered by an upper pad in order to position the air spring layer. 
     
     
         5 . The active supporting device for the health bed according to  claim 4 , wherein the upper pad is selected from the group consisting of: memory foam and latex pad. 
     
     
         6 . The active supporting device for the health bed according to  claim 1  further comprising a three-way tube, a first-way tube of the three-way tube being connected to the end of the air tube that is through the penetrating hole of the cushion in order to exposed from the open of the bottom surface of the mattress, a second-way tube of the three-way tube being connected to the control switches, and a third-way tube of the three-way tube being connected to the pressure sensors for that the pressure sensors detect the pressure values of the gasbags. 
     
     
         7 . The active supporting device for the health bed according to  claim 1 , wherein the control device has an input interface and is selected from the group consisting of: a PC (personal computer), a laptop and a PDA. 
     
     
         8 . The active supporting device for the health bed according to  claim 7 , wherein the input interface of the control device is selected from the group consisting of: buttons, keys and a touch screen. 
     
     
         9 . A method for actively supporting a health bed comprising the steps of:
 (S 1 ) disposing an air spring layer on a top surface of a mattress, the air spring layer comprising a plurality of gasbags, each gasbag being connected to a control switch of a venting hole of an aerating/deflating device through an air tube, the air tube being connected to a pressure sensor so as to detect the pressure in the gasbag, then a detected result being sent to a control device, which starts up or shuts down the control switch according to the receiving signal of the detected result, so that the aerating/deflating device is able to aerate each gasbag or all gasbags simultaneously;   (S 2 ) the control device initially having a preset value and detecting whether the pressure of each gasbag is achieved to the preset value through the pressure sensor, the control device then determining the time period for aerating each gasbag to the preset value so as to obtain the curve of the vertebra of a human being according to the variable time periods of aerating the all gasbags, wherein the gasbag of the longest time period is corresponding to the waist of the human being; and   (S 3 ) after obtaining the curve of the vertebra of the human, the control device starting up the control switch, then the aerating/deflating device individually aerating each gasbag based on the curve after completely deflating the all gasbags, so that each aerated gasbag corresponding to the waist may fill up a gap between the gasbag and the mattress.
