In the related art, a heat exchange fluid medium circularly flows in a waterway inside the intelligent bedspread and exchanges heat at the same time, so that the intelligent bedspread achieves the effect of refrigeration or heating. And the waterway of traditional intelligent bedspread is single, if the waterway is blocked by extrusion, the circulation of heat exchange fluid medium can be seriously influenced or even blocked, so that the refrigerating and heating effects of the intelligent bedspread are greatly reduced, and the user experience is influenced. Therefore, the utility model provides the intelligent bedspread structure and the system, and the intelligent bedspread structure can reduce the adverse effect of waterway extrusion on the water circulation effect.

Referring now to fig. 1, the structure of the smart bed cover structure of the present utility model is shown in some embodiments. The intelligent bedspread structure comprises a bedspread main body 1, wherein backflow channels 2 are distributed in the bedspread main body 1, heat exchange fluid media are suitable for circulating in the backflow channels 2, the backflow channels 2 comprise an inflow channel 21 and an outflow channel 22 which are sequentially communicated, branch channels 3 are connected in parallel on the inflow channel 21 and the outflow channel 22, and at least two branch channels 3 are communicated through a bypass channel 4.

It will be appreciated by those skilled in the art that the heat exchange fluid medium flows into the bed cover body 1 along the inflow channel 21 of the return channel 2 and out of the bed cover body 1 along the outflow channel 22 to achieve water circulation, and that during water circulation, the cold or hot heat exchange fluid medium continuously transfers heat to the bed cover body 1 to change the temperature of the bed cover body 1 to achieve cooling or heating.

Further, as mentioned in the foregoing, the waterway of the conventional intelligent bedspread is single, and when the waterway is blocked due to the extrusion of one place of the inflow channel 21 or the outflow channel 22, the water circulation is seriously affected or even blocked, and the present utility model can bypass the blocked waterway position by the heat exchange fluid medium through the branch channel 3 by arranging the branch channel 3, thereby continuing the water circulation.

Under normal circumstances, a part of the heat exchange fluid medium flowing into the bed cover body 1 flows along the inlet channel 21 to the outlet channel 22, another part flows along the branch channel a1 to the outlet channel 22, and similarly, a part of the heat exchange fluid medium flows out of the bed cover body 1 along the outlet channel 22, and another part flows out of the bed cover body 1 along the branch channel b 1. When the x region of the inflow channel is blocked by extrusion, the heat exchange fluid medium can continue to flow from the branch channel a1 to the outflow channel 22; when the x region of the inflow channel and the y region of the branch channel a1 are blocked by pressing, the heat exchange fluid medium may flow along the bypass channel c to the branch channel b1 and thus to the outflow channel 22. Similarly, when a partial region of the outflow channel 22 is blocked by compression, the heat exchange fluid medium may flow out of the bedspread body 1 from the branch channel b 1; when the partial area of the branch channel b1 is blocked by compression, the heat exchange fluid medium may flow out of the bed cover body 1 through the outflow channel 22 or may flow into the outflow channel 22 through the bypass channel c before flowing out of the bed cover body 1 along the outflow channel 22.
