Description

Technical Field

[0001] The utility model relates to the technical field of local improved design of electric heating components, in particular to a superconducting heating component with a square structure. Background Art

[0002] With the rapid development of society and the continuous improvement of science and technology, people use different electrical appliances to adjust the temperature of their living environment in different seasons. For example, electric heating components are used for heating in spring or winter. Usually, low-power 220V fans are used in family life. Due to the limitation of their own structure or the low efficiency of heating wire, the conversion rate of electric energy to heat is low. In the colder winter, it cannot effectively respond to heating quickly. For example, the "little sun" heating equipment on the market now, but because it cannot blow out soft warm air, it is only suitable for heating in winter and cannot be used for seasonal changes. Its use scenario is limited. For this reason, there are heating and cooling fans with heating components made of superconducting heating belts on the market, and the heating body is installed in the exhaust duct of the fan blades or wind blades. Because the heating belt is very thin, it is affected by the strong exhaust airflow and the high-frequency vibration of the heating belt produces noise. Especially after the heating belt is used for a long time and frequently, it is affected by the thermal expansion and contraction of the heating belt, resulting in more obvious noise caused by high-frequency vibration.

[0003] In the prior art, the patent with announcement number CN214949850U discloses a silent superconducting heating device, in which the superconducting heat-generating belt is continuously supported and suspended by a plurality of mica sheets, at least one mica sheet can be displaced in the frame toward the side panel of the frame, and a fastening module is installed on the side panel, and the fastening module elastically stretches the displaceable mica sheet to move toward the adjacent side panel so that the superconducting heat-generating belt is always in a tight and stretched state. When the airflow generated by the fan blade passes through the superconducting heat-generating belt, since the superconducting heat-generating belt is elastically stretched by the fastening module and is in a tight state, high-frequency vibration will not be generated, thus avoiding the generation of noise and giving the user a good experience of a silent cooling and heating fan.

[0004] In the above technical solution, the structural design of the fastening module includes a stretching rod and a compression spring sleeved on the stretching rod. The stretching rod occupies a large space, making the size of the whole machine larger.

[0005] In order to solve one of the above problems, the present application provides a superconducting heating component with a square structure. Utility Model Content

A spring is used to assist in stretching the second insulating plate to maintain dynamic balance, so that the superconducting heating wire can always be in a tightened state due to heating expansion or cooling contraction during operation, effectively reducing the vibration noise caused by loose wires, and always being in a quiet working state.

[0009] Furthermore, the plate surfaces of the first insulating plate and the third insulating plate as described above are arranged in parallel, and the second insulating plate is moved along the plate surface of the first insulating plate or the third insulating plate by means of two springs.

[0010] Furthermore, as mentioned above, the first insulating plate and the third insulating plate are respectively processed with limiting holes, and both ends of the second insulating plate are respectively provided with limiting protrusions, which are movably assembled in the limiting holes.

[0011] Furthermore, the installation positions of the two springs are symmetrical.

[0012] Furthermore, as mentioned above, the first insulating plate and the third insulating plate are respectively processed with card slots, and both ends of the fourth insulating plate are respectively provided with card blocks, which are carded in the card slots.

[0013] Furthermore, a plurality of insulating sheets are clamped between the first insulating sheet and the third insulating sheet as described above, and each insulating sheet is provided with a plurality of limiting grooves, and the superconducting heating wire passes through the limiting grooves.

[0014] Furthermore, the distance between two adjacent limiting grooves matches the distance between two connected side protrusions.

[0030] Embodiment 2

[0031] Reference Figure 1-3 As shown, based on the technical solution of embodiment 1, a superconducting heating component with a square structure is provided. As for the specific structural design of the frame plate, the plate surfaces of the first insulating plate 1 and the third insulating plate 4 are arranged in parallel, and are generally designed to be placed horizontally. The second insulating plate 3 is moved along the plate surface of the first insulating plate 1 or the third insulating plate 4 by two springs 2, and the moving direction is close to or away from the fourth insulating plate 6.

[0032] As for the assembly method of the frame, the first insulating plate 1 and the third insulating plate 4 are respectively processed with limiting holes, and limiting protrusions are respectively provided at both ends of the second insulating plate 3. The limiting protrusions are movably assembled in the limiting holes. The limiting holes here can be blind holes or through holes. For the convenience of processing, they are usually designed as through holes. In addition, the installation positions of the two springs 2 are symmetrical. For the parameter selection of the two springs 2, the parameters include material, wire diameter, outer diameter, middle diameter, inner diameter, pitch, free height, total number of turns, effective number of turns, working stroke, maximum compression, elastic force, winding ratio, whether the two ends are tight, polished, and other requirements. Selecting springs 2 with the same parameters is convenient for subsequent replacement and maintenance, and the installation position can be designed symmetrically, so that the tension of the springs 2 on the second insulating plate 3 can offset each other in the vertical direction to avoid shaking in the vertical direction.

[0033] Furthermore, the first insulating plate 1 and the third insulating plate 4 are respectively processed with card slots, and the two ends of the fourth insulating plate 6 are respectively provided with card blocks, which are mounted in the card slots.

Among them, the insulating sheet 5 is processed with limiting grooves on one side, and the two adjacent insulating sheets 5 are centrally symmetrically arranged.

[0034] Embodiment 3

[0035] Reference Figure 1-3 As shown, based on the technical solution of embodiment 1, a superconducting heating component with a square structure, for the structural design of other auxiliary components, a first support plate 81 is installed on the first insulating plate 1, and a second support plate 82 is fixed on the third insulating plate 4. The first support plate 81 and the second support plate 82 are respectively connected to the spring 2. The function of the first support plate 81 and the second support plate 82 is to assist in enhancing the structural strength of the frame plate, especially at the connection part with the spring 2, due to the oblique elastic force, two support parts are required to assist in increasing the structural strength of the insulating plate to avoid being broken and shortening the working life.

[0036] Further, the power line includes a first power line 71 and a second power line 72, the terminal of the first power line 71 and one end of the superconducting heating wire 9 are riveted to the third insulating plate 4 by rivets; the terminal of the second power line 72 is riveted to the fuse 73, the fuse 73 is riveted to the thermostat 74, the thermostat 74 is riveted to the auxiliary power line, the terminal of the auxiliary power line and the other end of the superconducting heating wire 9 are riveted to the first insulating plate 1 by rivets, the rivet riveting plays a role in fixed installation, and the auxiliary parts are not easy to fall off. In addition, when there are two superconducting heating wires 9, the auxiliary power line also needs to connect the two ends of the two superconducting heating wires 9 at the same time through the connecting piece 75, refer to Figure 2 As shown, the surface of the superconducting heating wire 9 can also be coated with graphene or far-infrared radiation coating, which can improve the heat radiation effect on the basis of heat conduction, and of course, can also increase the insulation function. In addition, the insulating plate and the insulating sheet 5 can be made of insulating and high temperature resistant materials such as mica sheets or ceramic sheets.

[0037] Working principle: Since the superconducting heating wire 9 will undergo significant length changes due to thermal expansion and contraction during operation, the S-shaped winding protruding on the upper side of the frame may become loose or too tight, resulting in unstable operation and the generation of loud noise. Therefore, the actual winding of the superconducting heating wire 9 on the frame is a flexible connection method. Through the combination of the movable second insulating plate 3 and the oblique elastic force of the spring 2, the spacing between the second insulating plate 3 and the fourth insulating plate 6 can be automatically adjusted, so that the superconducting heating wire 9 wound on the second insulating plate 3 and the fourth insulating plate 6 can always maintain a relatively stable tension state, neither too loose nor too tight. In addition, since the two ends of the spring 2 are connected to the insulating plate, the first insulating plate 1 and the third insulating plate 4 are generally longer than the second insulating plate 3. In order to prevent the connection part of the spring 2 from being broken, it is necessary to add the first support plate 81 and the second support plate 82 to improve the structural strength.

[0040] The above is only a preferred specific embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above-mentioned embodiment, and the utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the utility model.
