Description

Technical Field

[0001] The utility model relates to the technical field of heating pads, in particular to a radiation-proof liquid heating pad. Background Art

[0002] Existing heated seat cushions or heated mattresses generally adopt a structure in which the heat-conducting wire is directly arranged inside the cushion body. This structure of heating cushions has safety hazards. When the temperature of the heat-conducting wire is too high, it will easily cause the cushion body to overheat and catch fire. In addition, the heat-conducting wire will also have a certain amount of electromagnetic radiation when it is energized. Long-term use is not good for human health.

[0003] To this end, we designed a bladder-type heating pad with thermal fluid inside, a thermal wire inside the thermal fluid, and an anti-radiation layer on the outer layer of the thermal wire. This avoids the problem of local overheating of the pad body and greatly reduces the radiation problem of the heating pad. It also improves the comfort of the pad when used and is highly practical.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A radiation-proof liquid heating pad comprises a cushion liquid sac, in which a radiation-proof heating wire is arranged, and the cushion liquid sac is provided with a wire hole for installing the radiation-proof heating wire and a water injection hole for injecting liquid, wherein the radiation-proof heating wire comprises a carbon fiber heating wire, and the outer layer of the carbon fiber heating wire is sequentially covered with an aluminum wire layer and an outer silicone insulating layer from the inside to the outside.

[0007] As a further preferred embodiment of the present invention: a plurality of flexible support partitions are arranged at intervals inside the seat cushion liquid sac, the flexible support partitions evenly divide the interior of the seat cushion liquid sac into a plurality of liquid storage cavities connected to the sides; the flexible support partitions are provided with support through holes for supporting the anti-radiation heating wire, and the anti-radiation heating wire runs through the plurality of support through holes.

[0008] As a further preferred embodiment of the present invention: a peripheral supporting air bag (7) is arranged around the seat cushion liquid bag.

[0009] As a further preferred solution of the utility model: the outer layer of the carbon fiber heating wire is coated with an inner silicone insulation layer, and the aluminum wire layer is wrapped around the outer side of the inner silicone insulation layer.

[0010] As a further preferred solution of the utility model: anti-slip bottom pads are provided at the bottom of the seat cushion liquid bag and the surrounding side support air bags.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The liquid heating pad replaces the traditional metal heating wire with a carbon fiber heating wire, and designs a silicone insulation layer and an aluminum wire layer for radiation protection on the outer layer of the heating wire. This can effectively reduce the radiation generated by the carbon fiber heating wire to the human body after being energized. At the same time, it adopts a combination of an intermediate liquid sac and a surrounding air sac, which greatly improves its comfort of use. At the same time, by arranging multiple flexible supporting partitions in the middle of the seat cushion liquid sac, the seat cushion liquid sac can maintain a stable shape after being expanded with water, and can also play a supporting and limiting role for the radiation protection heating wire, preventing the internal heating wire from tangling and other problems, facilitating subsequent maintenance. The structural design is scientific and reasonable, and it is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
