Description

Technical Field

[0001] The utility model relates to a heating mattress, in particular to a heating mattress containing graphene, and belongs to the technical field of bedding. Background Art

[0002] Currently, mattresses are primarily heated by electric blankets. However, because common electric blankets use heating wires, they have a small heating area, low thermal efficiency, short lifespan, fragility, easy breakage, poor contact, and are prone to fire and electric shock accidents. As a result, electric blankets are becoming less popular. Graphene, a new two-dimensional nanomaterial, is the only two-dimensional free-state atomic crystal discovered to date. It possesses unique physical and chemical properties, including optical, electrical, magnetic, and mechanical properties. Since its discovery in 2004, graphene has garnered significant attention not only in theoretical science but also in practical applications in electronics, optics, magnetism, biomedicine, catalysis, energy storage, and sensors. Consequently, researchers have combined graphene with mattresses, developing a variety of graphene-heated mattresses.

[0003] For example, the document with publication number CN213097159U discloses a graphene mattress with uniform thermal conductivity, which includes a mattress cover and a mattress body arranged inside the mattress cover. The mattress body is a sponge layer, and a heating layer is provided on the surface below the sponge layer. The heating layer includes an upper flame-retardant cloth, a PTC flexible graphene heating sheet, and a lower flame-retardant cloth stacked in sequence from top to bottom. The PTC flexible graphene heating sheet is electrically connected to a controller. This mattress effectively solves the problem of the existing mattress surface heating local coverage and uneven coverage, which may cause burns or fire risks when the temperature rises continuously. However, in reality, mattresses can usually be used for more than ten years, while graphene heating sheets have problems on the one hand and malfunction problems on the other hand. After a certain number of years of use (3 to 5 years), circuit aging or other problems may occur. However, since the graphene heating sheets in this type of mattress are completely wrapped in the mattress cover and are not easy to disassemble and assemble, when there is a problem with the graphene heating sheet, there is often a technical problem of being inconvenient to replace, and replacing the mattress as a whole leads to high costs for users.

[0004] Therefore, a heating mattress containing graphene is proposed herein. Utility Model Content

[0005] The utility model provides a heating mattress containing graphene, so as to solve the problem in the prior art that the graphene heating sheets are completely wrapped in the mattress cover and are inconvenient to disassemble and assemble, resulting in high cost for replacing the entire mattress.

[0006] The utility model is realized by the following technical solution: a graphene-containing heating mattress, comprising a base layer and a first sponge layer embedded in the surface of the base layer, a high-carbon steel spring installed on the upper surface of the first sponge layer, a second sponge layer laid on the upper end of the high-carbon steel spring, an insulating pad installed on the upper surface of the second sponge layer, and a heating pad fixed inside the insulating pad, wherein the insulating pad is provided with airbags inside, and the heating pads are provided in multiple numbers and separated by the airbags;

[0008] Furthermore, the insulating pad includes an upper pad layer and a lower pad layer, one side of the upper pad layer and the lower pad layer are fixed by a knitting process, and a first zipper is installed on the other side of the upper pad layer. The other side of the upper pad layer and the lower pad layer are fixed by the first zipper, and the upper pad layer and the lower pad layer are closed by the first zipper to form a placement cavity, and the heating pad is arranged in the placement cavity.

[0009] Furthermore, corresponding positions of the lower surface of the upper cushion layer and the upper surface of the lower cushion layer are fixed with interlocking buckles, a fixing buckle is fixed on the side of the heating pad, one side of the heating pad is fixed inside the placement cavity by the fixing buckle and the buckle, and a Velcro is fixed on the upper surface of the lower cushion layer, the heating pad is fixed to the upper surface of the lower cushion layer by the Velcro, and the position of the Velcro is set on the other side of the buckle.

[0010] Furthermore, a power cord is fixed to the side of the heating pad, a through hole corresponding to the power cord is opened on the surface of the lower cushion layer, an electrical wire box is fixed to the upper surface of the base layer, and the side of the heating pad is connected to the electrical wire box through the power cord passing through the through hole. The electrical wire box and the power cord are plugged in, and the length of the power cord exceeds the maximum deformation amplitude of the heating pad.

[0011] Furthermore, the side of the electrical wire box passes through the knitted cloth cover, a controller is fixed at one end of the electrical wire box, the surface of the controller is provided with control buttons and a display screen, a second zipper is fixed to the side of the knitted cloth cover, and the position of the first zipper corresponds to the second zipper.

[0012] Furthermore, the heating pad includes a heat-conducting layer, a graphene heating sheet and a latex layer. The heat-conducting layer is heat-conducting cotton. The width of the heating pad is 1 / 5-1 / 4 of the length of the mattress. The number of the heating pads matches the placement cavity.

[0013] Furthermore, the upper cushion layer and the lower cushion layer are both insulating flame-retardant cloth.

[0014] The utility model provides a heating mattress containing graphene, which has the following beneficial effects:

[0015] 1. The graphene-containing heating mattress sets multiple heating pads in the insulating layer and uses air bags to separate them. When a heating pad is damaged, only the damaged heating pad needs to be replaced without replacing the entire mattress, which reduces the replacement cost. The dispersed arrangement of the heating pads can reduce the impact of the failure of a single heating pad on the overall heating effect. At the same time, the use of air bags for separation can not only open the insulating layer to facilitate the replacement of heating pads, but also provide a certain degree of comfort and support, thereby enhancing the overall performance of the mattress.

[0016] 2. The graphene-containing heated mattress can quickly conduct the heat generated by the graphene heating plate to the knitted fabric cover through the thermal conductive layer, and the latex layer has a certain thermal insulation effect, which can prevent the rapid loss of heat. At the same time, the upper and lower layers of the insulating pad are both insulating flame-retardant cloth, which can reduce the risk of burns caused by heating pad failure and fire caused by short circuit or insulation failure of the heating pad.
