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.

Dependent claims

An active supporting device for a health bed comprising:

a mattress, an open being disposed on a bottom surface of the mattress, a cushion being wrapped around in the mattress and having a plurality of penetrating holes;
an air spring layer, comprising a top layer and a plurality of gasbags, each gasbag having a plurality of aerating/deflating holes in order to dispose the air spring layer on the surface of the cushion;
an air tube set, comprising a plurality of air tubes, one end of each air tube being connected to one of the aerating/deflating holes, another end of the air tube being through the penetrating hole of the cushion in order to exposed from the open of the bottom surface of the mattress;
an aerating/deflating device, having a plurality of venting holes, each venting hole being connected to a control switch, each of the control switches being connected to every air tube;
a pressure sensor set, comprising a plurality of pressure sensors, each pressure sensor being connected to each of the gasbags in order to detect a pressure inside each gasbag and send out a detected result;
a control device, having a plurality of aerating modes, which are curve modes formed after aerating the all gasbags in several times, being connected to the aerating/deflating device, the control switches and the pressure sensor set and receiving the detected results from the pressure sensor set;
wherein the control device firstly activates the control switches for aerating the pressure of the gasbags to a preset value through the aerating/deflating device and detects the time period for aerating each gasbag to the preset value via the pressure sensor so as to obtain a time curve that is the curve of the vertebra of a human being and further determine the gasbags corresponding to the waist of the human being, then completely deflating the gasbags and automatically aerating the gasbags according to the aerating modes of the control device to form the curve of the vertebra of the human being, the pressures of the gasbags corresponding to the waist of the human being being the top points of the curve of the vertebra of the human being so as to precisely support the waist of the human being.

A method for actively supporting a health bed comprising the steps of:

(S1) 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;
(S2) 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
(S3) 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.
