Abstract

The air mattress 2 comprises groups of air bags 21 and 22. The groups of airbags are connected to a control unit 1 which has an air pump 11. This pump supplies compressed air to a group of airbags 21 or 22 through conduits 24 and 25 respectively, as selected by control valve 12. When one group 21 is connected to the pump, air from the other group 22 drains or discharges through exhaust conduit 26 to heat sink layer 23 which is laid over the airbags 21,22. The air passes through exhaust holes 23a in the heat sink layer, taking away some heat and moisture to make the mattress dry and comfortable. The pump supply alternates between the airbag groups according to the position of valve 12 (figure 3). In an alternative (figure 4), the air bags are held within a heat sink layer 23 which is a hollow structure. There may be more than two groups of airbags.

As described above, the first airbags (21), the second airbags (22), and the heat sink layer (23) are connected to the controlling valve (12) with a first conduit (24), a second conduit (25), and an exhaust conduit (26) respectively, and the controlling valve (12) selects any two of the first airbags (21), the second airbags (22), and the heat sink layer (23) to be connected for fluid flow.
3] As described above, the heat sink layer (23) is laid over the first airbags (21) and the second airbags (22), and the controlling valve (12) operated by the control unit (1) alternates the first conduit (24) and the second conduit (25) to connect with the air pump (11), wherein the first conduit (24) connects with the exhaust conduit (26) while the second conduit (25) connects with the air pump (11).
4] With reference to FIG 3which is a plane view of FIG. 2 under another state and according to the heat sink structure for air mattress of the present invention, the first airbags (21) connected with the first conduit (24) and the second airbags (22) connected with the second conduit (25) are expanded and shrunken alternately. When any of the first airbags (21) and the second airbags (22) is shrunken, the air therein is drained out and flows into the corresponding conduit (24) or (25). Finally, the air flows into the heat sink layer (23) through the exhaust conduit (26) connected with the conduit (24) or (25), and the air is drained out from the breathed material part of the heat sink layer(23). Moreover, the exhausting air takes some heat and damp away, and makes the air mattress (2) more dry and comfortable.
5] The said heat sink layer (23) is made of breathed material and has a plurality of exhaust holes (23a) to exhaust the air therein. Therefore, when the first airbags (21) and the second airbags (22) are expanded and shrunken alternately, the air therein is drained out and flows into the heat sink layer (23) through the corresponding conduit (24) or (25) and the exhaust conduit (26). The air is drained out from the exhaust holes (23a) of the heat sink layer(23), and the exhausting air takes some heat and damp away to make the air mattress (2) more dry and
comfortable.
