Description

Technical Field

[0001] The utility model relates to the technical field of seat cushions, in particular to a graphene seat cushion. Background Art

[0002] Seat cushions are used to place on chairs to make the user more comfortable. In winter, when the indoor and outdoor temperatures are low, ordinary seat cushions do not have a heating function, which causes the user's buttocks to get cold when sitting on them. For people with poor physical fitness, it is very easy to cause gastrointestinal discomfort.

[0003] Installing a graphene heating sheet in a seat cushion can effectively solve the problem of the seat cushion not heating up, allowing the seat cushion to heat up in advance in winter, making it easier for users to use it. When using a common graphene seat cushion, the overall material of the cushion is relatively soft, resulting in a lack of stable support for the graphene heating sheet. As a result, when the user sits on the graphene seat cushion, the graphene heating sheet will be deformed. Over time, the deformation of the graphene heating sheet will be difficult to recover, which will affect the service life of the graphene heating sheet to a certain extent. In addition, when the graphene heating sheet heats up and down, the heat at the bottom will be lost and cannot be well utilized. Utility Model Content

[0004] The purpose of this application is to provide a graphene seat cushion to solve the problem raised in the above background technology that the existing graphene seat cushion will lack stable support for the graphene heating sheet due to the relatively soft overall material of the seat cushion when in use. As a result, when the user sits on the graphene seat cushion, the graphene heating sheet will be deformed accordingly. Over time, the deformation of the graphene heating sheet will be difficult to restore, which will affect the service life of the graphene heating sheet to a certain extent. In addition, when the graphene heating sheet generates heat from the top and bottom, the heat from the bottom will be lost more and cannot be well utilized.

[0005] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a graphene seat cushion, comprising an outer cloth cover, an insulation board and memory foam placed inside the outer cloth cover, a groove provided on the top of the insulation board, a graphene heating sheet installed inside the groove, the graphene heating sheet being located directly below the memory foam, a plurality of through holes provided on the memory foam, a rubber cover fixed in the through holes, a plurality of elastic bands fixed on the top of the memory foam, the plurality of elastic bands being arranged linearly, a plurality of first heat conduction holes provided on the top of the outer cloth cover, and a plurality of linearly arranged fixings installed on the top of the outer cloth cover, the top of the fixings being installed with a velvet layer.

[0006] Furthermore, the top of the memory foam is a wavy structure, and the through holes are opened in the valleys of the memory foam.

[0007] Furthermore, a silicone sleeve is fixed to the outside of the heat insulation board, and the silicone sleeve is located inside the outer cloth sleeve.

[0008] Furthermore, a plurality of carrier blocks are fixed to the bottom of the outer cloth cover, and the carrier blocks are arranged in a grid shape, and a plurality of protrusions are fixed on the carrier blocks.

[0009] Furthermore, the fixing component includes a Velcro fleece surface and a Velcro hook surface, the Velcro fleece surface is installed on the top of the outer cloth cover, the Velcro hook surface is installed on the bottom of the velvet layer, and the Velcro fleece surface and the Velcro hook surface are bonded and fixed.

[0010] Furthermore, a plurality of second heat conduction holes are provided on the Velcro hook surface.

[0011] In summary, the technical effects and advantages of the utility model are:

[0012] In the present invention, a heat insulation board is used to support the graphene heating sheet, and a groove on the top of the heat insulation board can just accommodate the graphene heating sheet, so that the graphene heating sheet will not be deformed when the user sits cross-legged during use, reducing the probability of damage to the graphene heating sheet due to deformation. The heat insulation board can largely isolate the graphene heating sheet from supplying heat downward, so that the heat released by the graphene heating sheet during operation can be better gathered upward. In this way, not only can the speed of temperature rise on the top of the seat cushion be increased, but also the heat released by the graphene heating sheet can be better utilized.

[0013] In the utility model, the Velcro hook surface in the fixing piece is fixed on the velvet layer, and the Velcro fur surface in the fixing piece is fixed on the top of the outer cloth cover. After the Velcro fur surface and the Velcro hook surface are bonded and fixed to each other, the velvet layer can be installed on the top of the outer cloth cover, so that the comfort of the seat cushion is enhanced. At the same time, this design makes it easier to disassemble and clean the velvet layer. BRIEF DESCRIPTION OF THE DRAWINGS

The use of the plurality of elastic bands 6 can help the memory foam 4 maintain its shape stability, a plurality of first heat conduction holes 7 are provided on the top of the outer cloth cover 1, and a plurality of linearly arranged fixings are installed on the top of the outer cloth cover 1, and a flannel layer 11 is installed on the top of the fixings;

[0023] The graphene heating sheet 3 is supported by the heat insulation board 2, and the groove on the top of the heat insulation board 2 can just accommodate the graphene heating sheet 3, so that the graphene heating sheet 3 will not be deformed when the user sits cross-legged during use, reducing the probability of damage to the graphene heating sheet 3 due to deformation. The heat insulation board 2 can largely isolate the graphene heating sheet 3 from supplying heat downward, so that the heat released by the graphene heating sheet 3 during operation can be better gathered upward. In this way, not only can the speed of temperature rise on the top of the seat cushion be increased, but also the heat released by the graphene heating sheet 3 can be better utilized.

[0024] Among them, a plurality of carrier blocks 9 are fixed to the bottom of the outer cloth cover 1, and the plurality of carrier blocks 9 are arranged in a grid shape. A plurality of protrusions 10 are fixed on the carrier blocks 9.

At the same time, this design makes it easier to disassemble and clean the flannel layer 11.

[0027] Working principle of this utility model:

[0028] Place the seat cushion on the seat so that the carrier block 9 and the protrusion 10 thereon are in close contact with the seat, and energize the graphene heating sheet 3 so that the graphene heating sheet 3 releases heat. The heat insulation board 2 isolates the seat cushion from downward heat conduction to a certain extent, so that the heat released by the graphene heating sheet 3 can be better concentrated on the top of the seat cushion, thereby improving the efficiency of heating up the top of the seat cushion. When the user sits on the seat cushion, the buttocks will not get cold. The memory foam 4 and the flannel layer 11 can improve the comfort of the seat cushion. After using the seat cushion for a period of time, the user can separate the Velcro fur surface 12 from the Velcro hook surface 13 to remove the flannel layer 11 from the seat cushion for easy cleaning of the flannel layer 11.
