Description

Technical Field

[0001] The present invention relates to the technical field of heating devices, and particularly to a graphene ceramic far-infrared heater. Background Art

[0002] A graphene ceramic far-infrared heater is a device that utilizes the characteristics of graphene and ceramic materials to achieve efficient heating through the principle of far-infrared heat generation. It can be used to manufacture heaters, floor heating, wall heating, hand warmers, hot compress devices, scientific research heating platforms, etc. The working principle of the graphene ceramic far-infrared heater is as follows: using ceramics as the base material, usually selecting ceramics such as alumina ceramics with high temperature resistance, good insulation, and strong thermal stability. A heating paste containing graphene is coated or printed on the surface of the ceramic. Graphene has excellent electrical and optical properties and is one of the carbon materials with the highest thermal conductivity. When the heater is powered on, graphene will quickly generate heat under the action of an electric field and transfer the heat in the form of far-infrared radiation. Far-infrared rays have radiation and penetration, and can directly transfer heat to the heated object without any medium, which is directly absorbed by the object and generates a self-heating effect, thus quickly and effectively heating the object.

[0003] In the field of scientific research experiments, precise control of heat distribution on the scientific research heating platform is crucial. For example, in experiments such as material synthesis and biological sample processing, it is necessary to precisely control the position, intensity, and range of heat transfer to the sample to ensure the accuracy and repeatability of the experimental results. However, the focal distance between the graphene heating layer on the existing graphene ceramic far-infrared heater and the heated object is often relatively fixed, resulting in a rigid thermal radiation distribution pattern and unable to be flexibly adjusted according to different experimental requirements. When facing diverse scientific research tasks, it is difficult to precisely achieve the required heating effect, which not only affects the experimental efficiency but also may increase experimental errors.

[0004] Therefore, the present invention aims to break through this dilemma and develop a graphene ceramic far-infrared heater with an adjustable focal length function to meet the requirements for heating accuracy and heat distribution control. Summary of the Invention

The lower output shaft of the double-shaft motor rotatably penetrates into the transmission cavity and is fixedly connected with a driving gear. The driving gear meshes with the transmission gear. A positioning component for positioning and restricting the output shaft of the double-shaft motor is also provided in the installation frame.

[0008] As a further setting of the present invention, external threads are symmetrically arranged on the lead screw, and the thread directions of the two external threads on the lead screw are opposite. The lead screw is respectively threadedly connected with the two lead screw nuts through the external threads.

[0009] As a further setting of the present invention, the positioning component includes positioning cylinders respectively fixedly installed on the inner walls of both sides of the installation frame.

This makes the heating more flexible during use and ensures better overall use effects.

[0017] 2. In the present invention, after the focal distance between the graphene heating layer and the object to be heated is adjusted, the positioning gear can be positioned by the positioning card, so as to synchronously position and limit the upper and lower output shafts of the biaxial motor, preventing the output shafts of the biaxial motor from reversing and causing the "X"-shaped rotating adjustment frame to cross-rotate, and further avoiding the drawback that the focal distance between the mounting frame and the graphene heating layer on the ceramic far-infrared heater main body and the object to be heated becomes unstable after adjustment, ensuring more reliable positioning after adjustment. Coupled with the fact that the "X"-shaped rotating adjustment frame itself has an "X" shape and also has good support stability, it ultimately helps to ensure stable heating of the object to be heated by the graphene heating layer on the subsequent ceramic far-infrared heater main body.

[0018] In summary, the present invention can not only quickly and effectively heat the object material, but also adjust the focal distance between the graphene heating layer and the object to be heated according to actual needs, avoiding the situation that the focal distance between the existing graphene heating layer and the object to be heated is fixedly set, resulting in a rigid thermal radiation distribution pattern and being unable to be flexibly adjusted according to different experimental requirements, thus making it difficult to accurately achieve the required heating effect when facing diverse scientific research tasks. This makes the heating more flexible during use, and the positioning after adjustment is more reliable, which is conducive to ensuring the stable heating of the object to be heated by the graphene heating layer on the ceramic far-infrared heater and ensuring better overall use effect.

And the magnetic properties of the first electromagnet 25 and the second electromagnet 26 attract each other after being energized.

[0032] Among them, a guiding ball 29 is rotatably installed on the active block 27. A ball guiding groove is provided on the side wall of the positioning cylinder 20. The guiding ball 29 is in rolling connection with the ball guiding groove in the horizontal direction.

[0033] In this embodiment, vertical sliders 30 are provided on both sides of the mounting frame 5. Slide rails 31 are provided on the side wall of the housing 1. The vertical sliders 30 are slidably installed on the slide rails 31 in the vertical direction. Both ends of the top of the "X"-shaped rotating and adjusting frame 15 are rotatably connected with horizontal sliders 16. A horizontal chute is provided on the bottom side of the mounting frame 5. The horizontal sliders 16 are slidably installed in the horizontal chute. A sliding through groove 18 is provided on the bottom inner wall of the chute 17. The linkage slider 13 slidably penetrates through the sliding through groove 18 in the horizontal direction.

[0034] Among them, temperature sensors 6 are provided at the four corner positions of the bottom of the heat conducting block 202. The controller 7 controls the double-shaft motor 8, as well as the electrical control connections of the first electromagnet 25 and the second electromagnet 26 according to the temperature information sensed by the temperature sensors 6.

[0035] Such as Figures 1-6As shown, when the graphene ceramic far-infrared heater is used, the material or sample to be heated in the scientific research experiment is placed on the heating table 2, and the ceramic far-infrared heater body 4 is powered on. The graphene heating layer 401 will quickly generate heat under the action of the electric field, and transfer the heat upward in the form of far-infrared radiation. The far-infrared ray has radiation power and permeability, and can directly transfer the heat to the heated object such as the material or sample to be heated on the heating table 2. The heated object directly absorbs and produces a self-heating effect, thereby heating the object quickly and effectively. In addition, the focal length between the graphene heating layer 401 on the graphene ceramic far-infrared heater and the heated object can be adjusted according to actual needs during heating. That is, during adjustment: the controller 7 is used to automatically control the operation of the dual-axis motor 8, the first electromagnet 25, and the second electromagnet 26 according to the information sensed by the temperature sensor 6. Since the first electromagnet 25 and the second electromagnet 26 will generate electromagnetic force and attract each other after being powered on, the second electromagnet 26 can move toward the first electromagnet 25 and be attracted together. When the second electromagnet 26 is attracted and moves, it also drives The movable block 27 moves to the left and compresses the return spring 28. At the same time, when the movable block 27 moves to the left, it drives the positioning card 23 to move outward through the movable connecting rod 21 and the positioning block 22, thereby releasing the positioning of the positioning gear 24 by the positioning card 23, thereby releasing the positioning restriction of the dual-axis motor 8; then, by controlling the forward and reverse operation of the dual-axis motor 8, the driving gear 9 is driven to rotate and the transmission gear 10 is meshed and transmitted, thereby driving the screw rod 11 to rotate. Since the thread directions of the two external threads 1101 on the screw rod 11 are set in opposite directions, when the screw rod 11 rotates, the screw nut 12 can be moved on both sides of the screw rod 11 When the screw nut 12 moves, it also drives the two rotating frames on the "X"-shaped rotating adjustment frame 15 to rotate crosswise through the linkage slider 13 and the adapter slide 14. In this way, when the two screw nuts 12 move toward each other, the mounting frame 5, the ceramic far-infrared heater body 4 and the graphene heating layer 401 will move upward; conversely, the mounting frame 5, the ceramic far-infrared heater body 4 and the graphene heating layer 401 will move downward, which can make the mounting frame 5, the ceramic far-infrared heater body 4 and the graphene heating layer 401 move downward. 1 can be adjusted upward or downward, so that the focal length between the graphene heating layer 401 on the graphene ceramic far-infrared heater and the heated object can be flexibly adjusted according to actual needs during heating, avoiding the problem that the focal length between the graphene heating layer and the heated object in the existing heating technology is fixed, which makes the thermal radiation distribution pattern rigid and cannot be flexibly adjusted according to different experimental requirements, resulting in difficulty in accurately achieving the required heating effect when facing diverse scientific research tasks, ultimately making the heating more flexible in use and ensuring better overall use effect.

[0036] In addition, after the focal distance between the graphene heating layer 401 and the object to be heated is adjusted, the controller 7 will control the power-off of the first electromagnet 25 and the second electromagnet 26. Finally, the mutual magnetic attraction between the first electromagnet 25 and the second electromagnet 26 is released. At the same time, under the reset action of the return spring 28, the positioning card 23 can position the positioning gear 24, so as to synchronously position and limit the upper and lower output shafts of the dual-axis motor 8, preventing the output shafts of the dual-axis motor 8 from reversing and causing the "X"-shaped rotating adjustment frame 15 to cross-rotate, thereby avoiding the drawback that the focal distance between the graphene heating layer 401 on the mounting bracket 5 and the ceramic far-infrared heater main body 4 and the object to be heated becomes unstable after adjustment, ensuring more reliable positioning after adjustment, and being beneficial to ensuring the stable heating use of the graphene heating layer 401 on the subsequent ceramic far-infrared heater main body 4 for the object to be heated.

[0037] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
