The invention relates to a cold and hot dual-purpose seat cushion comprising a cushion body and a temperature controller; a circulating pipeline is embedded in the cushion body; a human body sitting induction piece is arranged on the surface of the cushion body; the temperature controller comprises a main control unit, a circulating pump, a temperature exchange box, a semiconductor, a power supplyand a power supply commutator; the circulating pump is connected with the temperature exchange box and pumps out liquid in the temperature exchange box and pumps the liquid into the circulating pipeline, the semiconductor is in heat conduction fit with the surface of the temperature exchange box, and the power supply and two wiring terminals of the semiconductor are connected in series to form aloop for supplying power to the semiconductor; the power supply commutator is connected to the loop and used for controlling the flow direction of current of the loop when the power supply commutatoris triggered, and the human body sitting induction sheet, the circulating pump, the power supply and the power supply commutator are electrically connected with the main control unit. The semiconductor is used for refrigerating or heating; the human body sitting induction piece is mounted on the cushion, starting and pausing of the main control unit are controlled through connection and disconnection of the human body sitting induction piece, a switch is switched on after a human body sits on the cushion, when the human body leaves the seat, the switch is switched off, and the human body sitting induction piece can be a thin-film conductive switch or an infrared sensor or a photoelectric sensor .

    本发明涉及一种冷热两用座垫,包括垫本体与控温机,所述垫本体内嵌有循环管道,所述垫本体表面上设有人体坐下感应片,所述控温机包括主控单元、循环泵、温度交换盒、半导体、电源和电源换向器,所述循环泵与温度交换盒连接并将温度交换盒内液体抽出且泵入循环管道内,所述半导体与温度交换盒表面热传导配合,所述电源与所述半导体的两个接线端子串联成一个回路用以为所述半导体供电;所述电源换向器连接于所述回路用于在被触发时控制该回路的电流的流向,所述人体坐下感应片、循环泵、电源和电源换向器分别与主控单元电性连接。本发明利用半导体制冷或发热,坐垫上安装了人体坐下感应片,通过人体坐下感应片的接通和断开来控制主控单元的启动和暂停,当人体坐上后开关接通,当人离开坐位开关接通,人体坐下感应片可以为薄膜导电开关或红外线传感器,或光电传感器。
