Description

Technical Field

Background Art

[0002] Due to its excellent electrical conductivity and thermal conductivity, graphene is widely used in the field of heating materials. Traditional graphene heating plates usually adopt a fixed structure design, and the contact area and pressure between the heating layer and the heat conduction panel cannot be adjusted, resulting in insufficient temperature control accuracy. In addition, there is a lack of an effective temperature feedback mechanism in the prior art, making it difficult to achieve dynamic temperature control adjustment, which affects the use effect and safety.

[0003] Currently, most graphene heating plates on the market adopt a simple resistance heating method, and temperature adjustment depends on an external controller, with a slow response speed and prone to temperature fluctuations. Some products attempt to improve the temperature control performance by adding sensors, but the combination method of the sensors and the heating layer is unreasonable, resulting in a lag or distortion of the feedback signal. In addition, the mechanical structure stability of the heating plate is insufficient, and problems such as poor contact or deformation are likely to occur after long-term use, affecting the heating efficiency and service life.

[0004] Therefore, there is a need to provide a graphene heating plate assembly with a simple structure, precise temperature control, and sensitive feedback. Summary of the Invention

Detailed implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1 to 8 shown, the present invention is a graphene heating plate assembly with temperature control adjustment, and this heating plate assembly can be used in furniture principles such as wall panels or floor panels; specifically, this graphene heating plate assembly with temperature control adjustment includes a substrate 1, an insulating layer 2, a graphene heating layer 3, and a heat conducting panel 4 arranged in sequence from bottom to top. Further, temperature adjusting components 5 are arranged on both sides of the graphene heating layer 3, and the temperature adjusting component 5 includes an adjusting screw 51 rotatably arranged at the edge of the graphene heating layer 3. More specifically, opposite-handed adjusting nuts 52 are threadedly connected to both ends of the adjusting screw 51, and one end of the adjusting nut 52 is connected to a heat conducting pressing block 53. Preferably, the heat conducting pressing block 53 penetrates through the graphene heating layer 3 and is slidably connected to the substrate 1 through an inclined slider structure. When the adjusting screw 51 is rotated, the adjusting nut 52 will drive the heat conducting pressing block 53 to move obliquely, thereby driving the graphene heating layer 3 to move up and down to realize the adjustment of the contact pressure.

[0030] As Figures 1 to 7 shown, an adjusting groove 31 for installing the adjusting screw 51 is opened at the edge of the graphene heating layer 3; furthermore, the adjusting screw 51 and the adjusting groove 31 are connected through a supporting block 32, the supporting block 32 is fixedly installed in the adjusting groove 31, and the adjusting screw 51 is rotatably arranged in the supporting block 32. Specifically, an adjusting knob 54 is installed at one end of the adjusting screw 51, and the surface of the adjusting knob 54 is provided with anti-slip lines for convenient manual operation. Preferably, as Figure 5As shown, a limiting disk 55 is also connected to the side of the graphene heating layer 3. A plurality of positioning holes 541 are formed in the adjusting knob 54, and positioning pins 542 are inserted into the positioning holes 541. Limiting holes 612 corresponding to the positioning pins 542 are formed in the limiting disk 55. By pushing the positioning pins 542 into the limiting holes 612, the position of the adjusting knob 54 can be fixed to prevent temperature deviation caused by accidental touch.

[0031] As Figure 2 shown, a support arm is formed on the side of the heat-conducting pressing block 53, and an elastic feedback assembly 6 is arranged on the graphene heating layer 3. Further, the elastic feedback assembly 6 includes a feedback slider 61 slidably arranged in the graphene heating layer 3. The feedback slider 61 is located below the support arm of the heat-conducting pressing block 53, and the support arm can be used to push and move the feedback slider 61 downward. Specifically, a temperature sensing rod 62 is connected to the bottom of the feedback slider 61. When the heat-conducting pressing block 53 moves downward to compress the feedback slider 61, the temperature sensing rod 62 contacts the substrate 1 and feeds back a temperature signal. Preferably, a heat-conducting rubber pad 621 is installed at the bottom end of the temperature sensing rod 62 to enhance the sensitivity and accuracy of temperature detection. A return spring 63 is arranged between the feedback slider 61 and the graphene heating layer 3 to ensure that the feedback slider 61 can quickly reset after the pressure is released.

[0032] As Figure 3 shown, a plurality of heat dissipation grooves 41 are arranged on the surface of the heat-conducting panel 4. Further, the heat dissipation grooves 41 are arranged in a wavy pattern, effectively increasing the heat dissipation area and improving the heat dissipation efficiency.

[0033] Preferably, in order to specifically realize that the heat-conducting pressing block 53 can slide obliquely and ensure that it does not fall off, a guiding groove 11 is arranged on the inner bottom surface of the substrate 1, and an oblique slider structure is formed at the bottom of the heat-conducting pressing block 53. Correspondingly, an oblique sliding groove for sliding connection with the oblique slider structure is formed on the bottom side wall of the guiding groove 11. The sliding connection between the oblique slider structure and the guiding groove 11 further ensures the smoothness of the movement. In addition, as Figure 7 shown, guiding blocks 33 are slidably arranged on both sides of the graphene heating layer 3. The guiding blocks 33 are slidably connected with the inner side wall of the substrate 1 to provide a guiding function for the up and down movement of the graphene heating layer 3 and prevent deviation.

[0034] Preferably, the elastic feedback assembly 6 further includes a fixing plate 64 installed in the feedback chute 34. The fixing plate 64 and the feedback slider 61 are connected by a return spring 63, and the temperature sensing rod 62 penetrates through the fixing plate 64. Specifically, guiding arms 611 are arranged on both sides of the feedback slider 61, and guiding cavities 341 for sliding connection with the guiding arms 611 are formed on both inner sides of the feedback chute 34 to ensure the linear movement of the feedback slider 61 and avoid jamming.

[0035] Working principle of the present invention: When using the graphene heating plate assembly, first rotate the adjustment knob 54 to drive the adjustment screw 51 to rotate. Under the action of the thread, the adjustment nut 52 moves horizontally, pulling the heat conduction pressing block 53 to slide obliquely. The oblique movement of the heat conduction pressing block 53 pushes the graphene heating layer 3 to move up and down, thereby changing its contact pressure with the heat conduction panel 4 to achieve temperature adjustment. Specifically, the user rotates the adjustment knob 54 to drive the adjustment screw 51 to rotate, and then drives the adjustment nut 52 and the heat conduction pressing block 53 to move. When the heat conduction pressing block 53 presses down on the graphene heating layer 3, the contact pressure between the graphene heating layer 3 and the substrate 1 increases, and the heat transfer efficiency improves; on the contrary, the heat transfer efficiency decreases. At the same time, the heat conduction pressing block 53 compresses the feedback slider 61, so that the temperature sensing rod 62 contacts the substrate 1 and feeds back the real-time temperature signal. If the temperature is too high, the user can reduce the contact pressure by rotating the adjustment knob 54 in the reverse direction, thereby achieving dynamic temperature control.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
