Abstract:
1. A hot-cold cushion comprising a heat/cool device, a connecting tube and a cushion, wherein the heat/cool device having a thermo semiconductor chip, a thermoconductor, a fan, a heat dissipation member, a box with liquid, and a hydraulic pump is connected with circulating pipes inside the cushion by the connecting tube while the box with liquid, the hydraulic pump, and the thermoconductor are connected with the cushion in series so as to form a circulation loop for liquid; thus the liquid is sent from the box with liquid by the hydraulic pump, entering the thermoconductor for absorbing heat or cold generated by the thermo semiconductor chip, then into the circulating pipes of the cushion and returns back to the box with liquid; top side as well as bottom side of the thermoconductor is disposed with a thermo semiconductor chip respectively while the heat dissipation member with heat dissipation fin encloses the thermo semiconductor chip and thermoconductor and the fan is fixed on one side of the heat dissipation member along the direction of the heat dissipation fin for providing winds to the heat dissipation member; the connecting tube having an access pipeline and an exit pipeline is between the heat/cool device and the cushion and is connected with the heat/cool device and the cushion in series to form a liquid circulation loop; and the cushion with circulating pipes for connecting with the connecting tube.
