Description

Technical Field

[0001] This utility model relates to the technical field of heating devices, and in particular to a constant temperature heating device. Background Technology

[0002] A heating device is a device that converts electrical energy or other forms of energy into heat energy. Graphene, as a novel material, has been widely used in the field of heating devices due to its excellent thermal and electrical conductivity.

[0003] With the development of technology, in order to improve the user experience of billiard tables, heating devices are installed at the bottom of the billiard table to heat the table surface. The purpose is to heat and dry the tablecloth to cope with humid environments or rainy weather.

[0004] However, existing graphene heating panels are mainly used for floor heating, as exemplified by Chinese patent publication CN111586906A (Graphene Heating Panel) and CN108777888A (A Graphene Variable Frequency Heating Panel). Due to the lack of a proper mounting structure, existing graphene heating panels cannot reliably adhere to the bottom of the billiard table slate. Therefore, to ensure stable heating of the billiard table slate, it is necessary to improve existing graphene heating panels, leading to the constant temperature heating device proposed in this application. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a constant temperature heating device that can reliably adhere to the slate of a billiard table to stably heat the table clay.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A constant temperature heating device, comprising:

[0008] A heating element includes a base plate, an insulation plate, a graphene plate, and a fastening plate. The insulation plate has a stepped portion. The base plate is disposed on the side of the insulation plate away from the stepped portion. The graphene plate is disposed on the stepped portion. A groove is formed on one side of the fastening plate, and the fastening plate is fastened to the insulation plate so that both the graphene plate and the stepped portion are located within the groove.

[0009] A support frame is arranged around the heating element so that the support frame clamps the edges of the base plate and the buckle plate respectively, and the surface of the buckle plate is higher than the surface of the support frame.

[0010] Optionally, the support frame includes several frame strips and several connecting blocks, with each frame strip and each connecting block connected sequentially end to end, and each frame strip covering the edges of the base plate, the insulation board, and the buckle plate.

[0011] Optionally, both the frame strip and the buckle plate are made of aluminum.

[0012] Optionally, the frame includes a bottom block, a top block, a side block, and an inner block. The side block and the inner block are respectively connected to the bottom block and the top block, and there is a gap between the inner block and the side block. The top block and the bottom block extend away from the side block so that a material-locking groove is formed between the bottom block, the inner block, and the top block. The edges of the bottom plate, the insulation board, and the buckle plate are all located in the material-locking groove.

[0013] Optionally, the center of the top block is recessed away from the inner block, so that the top block is formed into an arc-shaped structure.

[0014] Optionally, the side block has a through hole, and the inner block has a screw hole. A fastener passes through the through hole and is screwed into the screw hole, so that the inner block deforms to move closer to the side block, thereby causing the end of the top block away from the side block and the end of the bottom block away from the side block to move closer to each other to clamp the edges of the bottom plate, the insulation board, and the buckle plate.

[0015] Optionally, the bottom block, the top block, the side block, and the inner block are integrally formed.

[0016] Optionally, the height difference between the surface of the buckle plate and the surface of the support frame is 1mm to 4mm.

[0017] Optionally, the insulation board is a polyurethane board.

[0018] Optionally, the base plate is made of iron.

[0019] Compared with the prior art, the present invention has at least the following advantages:

[0020] This utility model discloses a constant-temperature heating device, comprising a heating element and a support frame. The heating element includes a base plate, an insulation board, a graphene board, and a snap-on plate. The insulation board has a stepped portion, and the base plate is disposed on the side of the insulation board away from the stepped portion. The graphene board is disposed on the stepped portion, and a groove is formed on one side of the snap-on plate. The snap-on plate is snapped onto the insulation board so that both the graphene board and the stepped portion are located within the groove. The support frame is arranged around the heating element so that it clamps the edges of the base plate and the snap-on plate, and the surface of the snap-on plate is higher than the surface of the support frame. Thus, during installation, the constant-temperature heating device of this application can be quickly and securely locked to the bottom of the billiard table slab using bolts. Since the outer surface of the snap-on plate is higher than the support frame, the outer surface of the snap-on plate reliably adheres to the bottom of the billiard table slab. When the graphene board heats up, heat can be transferred to the billiard table slab through the snap-on plate. Attached Figure Description

[0028] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0029] like Figures 1 to 3 As shown, a constant temperature heating device 10 includes a heating element 100 and a support frame 200. The heating element 100 includes a base plate 110, an insulation plate 120, a graphene plate 130, and a buckle plate 140. The insulation plate 120 has a stepped portion 121. The base plate 110 is disposed on the side of the insulation plate 120 away from the stepped portion 121. The graphene plate 130 is disposed on the stepped portion 121. A groove is formed on one side of the buckle plate 140. The buckle plate 140 is fastened to the insulation plate 120 so that the graphene plate 130 and the stepped portion 121 are both located in the groove. The support frame 200 is disposed around the heating element 100 so that the support frame 200 presses and clamps the edges of the base plate 110 and the buckle plate 140 respectively, and the surface of the buckle plate 140 is higher than the surface of the support frame 200.

[0030] It should be noted that the step portion 121 is located on one side of the insulation board 120, the base plate 110 is attached to the side of the insulation board 120 away from the step portion 121, the graphene plate 130 is attached to the step portion 121, and the snap-on plate 140 is snapped into the insulation board 120, so that both the step portion 121 and the graphene plate 130 are located within the groove of the snap-on plate 140. The support frame 200 covers and fixes the insulation board 120 around its perimeter, so that the support frame 200 clamps and fixes the edges of the base plate 110, the insulation board 120, and the snap-on plate 140. The outer surface of the snap-on plate 140 is higher than the side of the support frame 200 closest to the snap-on plate 140. Thus, during installation, the constant temperature heating device 10 of this application uses bolts or the like to lock and fix the support frame 200 to the bottom of the billiard table slab. Since the outer surface of the buckle plate 140 is higher than the support frame 200, the outer surface of the buckle plate 140 is reliably attached to the bottom of the billiard table slab. When the graphene plate 130 heats up, the heat can be transferred to the billiard table slab through the buckle plate 140.

[0031] like Figure 1 As shown, in one embodiment, the support frame 200 includes a plurality of frame strips 210 and a plurality of connecting blocks 220. Each frame strip 210 and each connecting block 220 are connected end to end in sequence, and each frame strip 210 covers the edge of the base plate 110, the insulation board 120 and the buckle plate 140.

[0032] It should be noted that, to ensure the stable stacking of the base plate 110, insulation board 120, graphene board 130, and buckle plate 140, the support frame 200 is configured as a structure in which several frame strips 210 are connected end to end in sequence, wherein each frame strip 210 clamps and fixes the edges of the base plate 110, insulation board 120, and buckle plate 140. Furthermore, a connecting block 220 is used to connect and fix any two adjacent frame strips 210. For example, screws are used to lock and fix the connecting block 220 to the frame strip 210.

[0033] In one embodiment, both the frame strip 210 and the buckle plate 140 are made of aluminum. Thus, with the buckle plate 140 being made of aluminum, the heat generated by the graphene plate 130 can be effectively transferred to the slate of the billiard table via the buckle plate 140. Furthermore, making the frame strip 210 of aluminum ensures that the overall support frame 200 maintains sufficient structural strength while reducing its weight.

[0034] like Figure 3 As shown, in one embodiment, the frame strip 210 includes a bottom block 211, a top block 212, a side block 213, and an inner block 214. The side block 213 and the inner block 214 are respectively connected to the bottom block 211 and the top block 212, and there is a gap between the inner block 214 and the side block 213. The top block 212 and the bottom block 211 extend away from the side block 213, so that a material clamping groove 215 is formed between the bottom block 211, the inner block 214, and the top block 212. The edges of the bottom plate 110, the insulation plate 120, and the buckle plate 140 are all located in the material clamping groove 215.

[0035] It should be noted that there is a gap between the side block 213 and the inner block 214. Both ends of the short sides of the side block 213 and the inner block 214 are connected to the bottom block 211 and the top block 212, respectively, forming a hollow structure. The top block 212 and the bottom block 211 extend away from the side block 213, forming a non-closed material-holding groove 215 between the bottom block 211, the top block 212, and the inner block 214. This ensures that the edges of the base plate 110, the insulation board 120, and the buckle plate 140 are all located within the material-holding groove 215. Making the frame strip 210 a hollow structure effectively reduces its weight while ensuring sufficient structural strength. In one embodiment, the bottom block 211, top block 212, side block 213, and inner block 214 are integrally formed aluminum structures. This ensures that the frame strip 210 can have both high strength and reduced weight.

[0036] like Figure 1As shown, in one embodiment, the center of the top block 212 is recessed away from the inner block 214, so that the top block 212 is formed into an arc-shaped structure. In this way, the end of the top block 212 away from the side block 213 is bent toward the buckle plate 140, thus ensuring that the top block 212 stably clamps the buckle plate 140, the insulation board 120, and the bottom plate 110.

[0037] like Figure 4 As shown, in one embodiment, a through hole 2131 is provided on the side block 213, and a screw hole 2141 is provided on the inner block 214. A fastener is passed through the through hole 2131 and screwed into the screw hole 2141, so that the inner block 214 deforms to approach the side block 213, thereby causing the end of the top block 212 away from the side block 213 and the end of the bottom block 211 away from the side block 213 to approach each other to clamp the edges of the bottom plate 110, the insulation plate 120, and the buckle plate 140.

[0038] It should be noted that, in order for the top block 212 and bottom block 211 to reliably clamp and fix the base plate 110, insulation board 120 and buckle plate 140, a through hole 2131 is provided on the side block 213 and a screw hole 2 is provided on the inner block 214. The inner diameter of the through hole 2131 is larger than the inner diameter of the screw hole 2. Further, in one embodiment, the thickness of the side block 213 is greater than the thickness of the inner block 214. Further, in one embodiment, the fastener is a screw. After the screw passes through the through hole 2131, the screw is screwed into the screw hole 2. As the screw is tightened, since the thickness of the inner block 214 is smaller than the thickness of the side block 213, the inner block 214 will deform to move closer to the side block 213, thereby causing the top block 212 and bottom block 211 connected to the inner block 214 to move closer to each other, thereby reliably clamping and fixing the base plate 110, insulation board 120 and buckle plate 140.

[0039] In one embodiment, the height difference D between the surface of the buckle plate 140 and the surface of the support frame 200 is 1mm to 4mm. That is, the surface of the buckle plate 140 is 1mm to 4mm higher than the highest point of the top block 212 of the support frame 200, for example, it can be 2mm or 3mm. In this way, it is ensured that the surface of the buckle plate 140 can reliably fit against the bottom of the billiard table slate.

[0040] In one embodiment, the insulation board 120 is a polyurethane board. In this way, the insulation board 120 can prevent the heat generated by the graphene board 130 from being lost and transfer it to the buckle 140 as much as possible, thereby transferring it to the slate of the billiard table for heating.

[0041] Furthermore, in one embodiment, the base plate 110 is made of iron. Specifically, the base plate 110 is a 0.3mm thick iron sheet, which improves the overall structural strength of the constant temperature heating device 10.

[0042] In one embodiment, a heat insulation layer is provided on the side of the base plate 110 near the insulation board 120, such as a heat insulation paint applied by a spraying process. In this way, the heat generated by the graphene board 130 can be further prevented from being transferred to the base plate 110.

[0043] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
