Hydrothermal blanket

Abstract

The invention discloses a hydrothermal blanket comprising a cushion body, a heating device, a liquid inlet pipe and a liquid outlet pipe. One end of the liquid inlet pipe and one end of the liquid outlet pipe are both communicated with the heating device, and the other end of the liquid inlet pipe and the other end of the liquid outlet pipe are both communicated with the cushion body. The hydrothermal blanket further comprises a driving device driving liquid to flow in a circulating mode. The cushion body comprises a first layer body and a second layer body which are both made of insulation and waterproof materials, wherein the periphery of the first layer body and the periphery of the second layer body are mutually sealed and pressed, the two layer bodies are mutually pressed to form a plurality of pressing points and a first pressing line, gaps are formed among the pressing points to form flow channels for fluids to flow, and the pressing line divides the flow channels into a liquid inlet unit and a liquid outlet unit. No pipe bodies are distributed in the whole cushion body, discomfort cannot be caused, and the hydrothermal blanket can be folded at will, and is convenient to carry and long in service life; and the flow channels are multi-directional, liquid can flow at will in the flow channels, blocking phenomena of heat transfer cannot occur, and uniform temperature distribution of the whole blanket body is guaranteed.

Description

technical field [0001] The invention relates to a household article, in particular to a water heating blanket with a health care function. Background technique [0002] The shadow of the electric blanket is indispensable for heating in winter. The electric blanket is easy to use and heats up quickly. These advantages make consumers choose this heating tool. Early electric blankets were mostly heated by resistance wires, which have magnetic field radiation, and long-term use will endanger human health. Therefore, in recent years, water heating blankets that use water hoses instead of resistance wires for heat transfer have appeared. Finally, it enters the hose in the pad body through the connecting pipe, and the water circulates in the hose to achieve the effect of heat transfer. [0003] Chinese patent CN1806723A discloses a water heating blanket, which includes a pad body, an electric heating element and a hot water pipe. The heat dissipation in the pad body realizes the ...

Problems solved by technology

But the heat transfer process is much smoother, but the human body occupies a larger area, especially the double bed, it is easier to compress the thin flow tube, and the diameter of the thin flow tube is reduced, its service life is also greatly reduced, and it is prone to leakage.

At the same time, when not in use or when it needs to be carried, the water heating blanket is usually folded or curled, which will damage the hose or thin tube in the blanket body, or accelerate the aging of the hose or thin tube, and it should not be under pressure during carrying , very inconvenient
