Description

Technical Field

[0001] The utility model relates to the technical field of local improved design of heating elements, in particular to a superconducting heating element with a disc 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 CN214701287U discloses a disc-type superconducting heating module, in which the superconducting heating belt is suspended in a spiral on a bracket, the bracket includes a positioning frame located in the central area, and a plurality of cantilevers extending from the positioning frame to the peripheral side, each cantilever is provided with an insulating support sheet, the insulating support sheet includes a sheet-like body and a plurality of support hooks extending from the sheet-like body and perpendicular to the extension direction of the cantilever, a slot is provided on one side of the support hook or between two adjacent support hooks, and the superconducting heating belt is installed on the bracket through the slot. Since the superconducting heating belt is basically installed on the bracket in a symmetrical shape, when the airflow generated by the fan passes through the heating module, a uniformly distributed warm airflow can be generated, which brings a good experience to the user.

[0004] In the above technical solution, the insulating support sheet is buckled on the cantilever, and the upper gap of the insulating support sheet forms a slot for buckling the superconducting heat-generating belt. Although the surrounding assembly and fixation problem of the superconducting heat-generating belt can be solved, this structure cannot overcome the tension problem of the superconducting heat-generating belt caused by thermal expansion and contraction, as well as the noise problem caused by it.

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

[0006] The purpose of the utility model is to solve the problems existing in the prior art, and a superconducting heating element with a disc structure is proposed. The disc structure is designed to use the elastic force of a spring to exert on an insulating sheet to maintain dynamic balance, so that the superconducting heating wire can always be in a tightened state due to heating expansion or cooling contraction when working, thereby reducing the vibration noise caused by loose wire.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a superconducting heating element with a disc structure, comprising a bracket, wherein the bracket comprises an outer circular frame and an inner circular frame, the outer circular frame and the inner circular frame are connected by a plurality of spokes, and a clamping block is provided on the side of the spoke;

[0008] An insulating sheet, which is movably mounted on the clamping block and elastically slides along the length direction of the spoke, and a plurality of clamping grooves are also processed on the insulating sheet;

[0009] A superconducting heating wire passes through the slot, spirals around, and has two ends respectively fixed on the insulating sheet.

[0010] Furthermore, at least one of the insulating sheets is movably mounted on the clamping block and elastically slides along the radial direction of the outer circular frame.

[0011] Furthermore, the insulating sheet and the outer circular frame or the inner circular frame as described above are connected via a spring.

[0012] Furthermore, a limiting column is provided on the inner circular frame as described above, and a compression spring is provided on the outer sleeve of the limiting column, and the compression spring contacts the end of the insulating sheet.

[0013] Furthermore, an open groove is processed on the above-mentioned limiting column, and one end of the insulating sheet is movably inserted in the open groove.

[0014] Furthermore, the spring described above is a tension spring, and two ends of the tension spring are respectively connected to the insulating sheet and the outer circular frame.

[0015] Furthermore, the spokes as described above are processed with a retreat portion near the outer circular frame, and a tension spring is arranged in the cavity of the retreat portion.

[0016] Furthermore, the insulating sheet as described above is processed with a through hole, and the outer circular frame is processed with a limiting groove, and the two ends of the tension spring are respectively clamped in the through hole of the insulating sheet and on the limiting groove.

[0017] Furthermore, the spokes as described above are evenly arranged and provided with blocks of a square structure, and rectangular holes for accommodating the blocks are processed on the insulating sheet.

[0018] Furthermore, it also includes a wire, which is electrically connected to the superconducting heating wire. A terminal is provided at the end of the wire, and the terminal is riveted to the insulating sheet. Both ends of the superconducting heating wire are fixed to the insulating sheet by rivets.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows: the device is designed as a disc structure, and the elastic force of the spring is applied to the insulating sheet, so that the insulating sheet elastically slides on the spokes to maintain dynamic balance. When the superconducting heating wire is working, it can always be in a tightened state due to heating expansion or cooling contraction, reducing the vibration noise caused by loose wire.

[0020] A superconducting heating wire is wound on insulating sheets and other insulating and high-temperature resistant materials. This superconducting heating wire is extremely thin and can conduct heat very quickly. By matching it with a suitable fan, the heat can be quickly taken out, thereby quickly generating warm air. It can achieve 2-second heating, and after power failure, there is no residual heat and the temperature can be cooled within 2 seconds. It is used for heaters, heating and cooling fans, air heating equipment, drying equipment, drying equipment, etc. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1

[0033] Reference Figure 1-3 As shown, a superconducting heating element with a disc structure of the utility model comprises a bracket, wherein the bracket comprises an outer circular frame and an inner circular frame, the outer circular frame and the inner circular frame are connected by a plurality of spokes, the spokes are located in the diameter direction of the outer circular frame, and a clamping block is provided on the side of the spoke; an insulating sheet, wherein the insulating sheet is movably mounted on the clamping block and elastically slides along the length direction of the spoke, specifically, the insulating sheet moves along the clamping block with the aid of the elastic force of a compression spring, and a plurality of clamping grooves are also processed on the insulating sheet; a superconducting heating wire, wherein the superconducting heating wire passes through the clamping groove, spirals around, and both ends are respectively fixed on the insulating sheet, that is, both ends of the superconducting heating wire are fixed, but the middle part is clamped on the insulating sheet and can adjust its own tension as the insulating sheet elastically slides, so as to avoid loose wire due to expansion due to heating or contraction due to cooling, and generate vibration noise during operation.

[0034] Reference Figure 2 and Figure 3It can be seen that the spokes are evenly arranged and provided with blocks of square structure, and the insulating sheet is processed with rectangular holes for accommodating the blocks. As for the assembly relationship between the insulating sheet and the spokes, it is necessary to satisfy that at least one of the insulating sheets is movably mounted on the blocks and elastically slides along the radial direction of the outer circular frame, and the other insulating sheets can be fixed on the spokes, that is, the rectangular holes on the spokes just match the blocks on the spokes, and a transition fit is generally selected, which makes assembly and disassembly convenient and quick. In addition, for the insulating sheet that needs to be movably mounted on the spokes, the insulating sheet and the outer circular frame or the inner circular frame are connected by a spring, and the shape design of the blocks is usually smaller than the size of the rectangular holes on the insulating sheet, leaving enough sliding distance, that is, it is adapted in the width direction of the rectangular hole, but smaller than the size of the rectangular hole in the length direction. Figure 3 The card block is designed to be L-shaped, so that it has a certain limit function.

[0035] Furthermore, it is necessary to provide a limit column on the inner circular frame, and a compression spring is provided on the outer sleeve of the limit column, and the compression spring contacts the end of the insulating sheet, so that the compression spring will not detach from the limit column, and the insulating sheet is in the limit position when it touches the limit column. On this basis, in order to ensure that the compression spring does not detach and increase the elastic movement space of the insulating sheet at the same time, an open groove is processed on the limit column, and one end of the insulating sheet is movably inserted in the open groove, that is, the open groove on the limit column can also be used as the activity space of the insulating sheet. Finally, in order to avoid the spacing between the limit column and the spoke being too small, which affects the installation of the compression spring, the limit column can be designed with enough space at the position where the spoke is close to the inner circular frame. The diameter parameter selection of the compression spring is less restricted, and there will be no problem of narrow installation space.

[0036] Embodiment 2

[0037] Reference Figure 4-6As shown, based on the technical solution of the first embodiment, a superconducting heating element with a disc structure includes a bracket 1, wherein the bracket 1 includes an outer circular frame 11 and an inner circular frame 13, wherein the outer circular frame 11 and the inner circular frame 13 are connected by a plurality of spokes 12, similar to the design of a wheel hub, wherein the outer circular frame 11 and the inner circular frame 13 are two annular circular frames respectively, and the two are connected by spokes 12 of equal length, wherein the spokes 12 are in the diameter direction of the circular circular frame, and a clamping block 121 is provided on the side of the spoke 12 for assembling an insulating sheet 4; the insulating sheet 4, wherein the insulating sheet 4 is movably mounted on the clamping block 121 and elastically moves along the length direction of the spoke 12 Sliding, by designing a spring 5 on the bracket 1, the insulating sheet 4 can slide along the length direction of the spoke 12 to change its working position, and a plurality of slots are also processed on the insulating sheet 4; the superconducting heating wire 2 passes through the slot and spirals around and is fixed on the insulating sheet 4 at both ends. Since the position of the insulating sheet 4 can be fine-tuned, the tension of the superconducting heating wire 2 coiled on the insulating sheet 4 can also be adjusted, thereby solving the technical problem of excessive noise in the operation of the superconducting heating wire 2, so that the heating expansion or cooling contraction can always be in a tight state, reducing the vibration noise caused by loose wire.

[0038] Reference Figure 5 and Figure 6 It can be seen that for the assembly relationship between the insulating sheet 4 and the spoke 12, it is necessary to satisfy that at least one of the insulating sheets 4 is movably mounted on the clamping block 121 and elastically slides along the radial direction of the outer circular frame 11, and the insulating sheet 4 can slide along the length direction of the spoke 12 under the elastic force of the spring 5 installed on the bracket 1. Specifically, the spring 5 is selected as a tension spring 52, and the two ends of the tension spring 52 are respectively connected to the insulating sheet 4 and the outer circular frame 11. In order to leave installation space for the tension spring 52, the spoke 12 is processed with a retreat portion 122 near the outer circular frame 11, and the tension spring 52 is arranged in the cavity of the retreat portion 122. In addition, in order to prevent the tension spring 52 from loosening and being unstable during operation, a through hole is processed on the insulating sheet 4, and a limiting groove is processed on the outer circular frame 11, and the two ends of the tension spring 52 are respectively stuck in the through hole of the insulating sheet 4 and on the limiting groove.

[0039] Furthermore, the spokes 12 are evenly arranged and provided with a block 121 of a square structure. A rectangular hole for accommodating the block 121 is processed on the insulating sheet 4. The structural design of the block 121 can have an assembly method that transitions with the rectangular hole, so that the insulating sheet 4 can be fixedly embedded in the spokes 12 and cannot move. It can also be assembled in a gap-matched manner with the rectangular hole, so that the insulating sheet 4 can be movably installed on the spokes 12 and move toward the direction of the outer circular frame 11 under the tension of the tension spring 52. In this gap-matched manner, the shape design of the block 121 is usually smaller than the size of the rectangular hole on the insulating sheet 4, leaving enough sliding distance, that is, it is adapted in the width direction of the rectangular hole, but smaller than the size of the rectangular hole in the length direction.

[0040] Embodiment 3

[0041] Reference Figure 1-6 As shown, on the basis of the technical solution of embodiment 1 or embodiment 2, a superconducting heating element of a disc structure further includes a wire 3, which can be connected to an external power supply, and the wire 3 is electrically connected to the superconducting heating wire 2. The end of the wire 3 is provided with a terminal, and the terminal is riveted on the insulating sheet 4. The two ends of the superconducting heating wire 2 are fixed on the insulating sheet 4 by rivets. In addition, in the structural design of the spokes 12, each spoke 12 is generally provided with two blocks 121, so that the installation of the insulating sheet 4 is stable or its sliding direction is limited. All spokes 12 are arranged at equal angles as a whole, and the number can be an odd number or an even number. For the number of springs 5 ​​installed, in order to ensure that there is enough tension on the coiled superconducting heating wire 2, at least two springs 5 ​​are provided, and the installation position is generally symmetrically arranged. Of course, springs 5 ​​can also be installed at the ends of all spokes 12. In addition, the surface of the superconducting heating wire 2 can also be increased with a graphene coating or a far-infrared radiation coating, which can improve the thermal radiation effect on the basis of heat conduction, and of course, the insulation function can also be increased. In addition, the above-mentioned insulating sheet 4 can be selected from insulating and high-temperature resistant materials such as mica sheets or ceramic sheets.

[0042] Working principle: Since the superconducting heating wire 2 will undergo significant length changes due to thermal expansion and contraction during operation, it may become loose or too tight when it is coiled around the bracket 1, resulting in unstable operation and loud noise. Therefore, the layout design of the superconducting heating wire 2 on the bracket 1 needs to select a flexible connection method. By installing a spring 5 on the bracket 1 in combination with an insulating sheet 4 that can slide in the length direction of the spoke 12, the insulating sheet 4 can be kept in a suitable position by elastic force, thereby automatically adjusting the tension of the superconducting heating wire 2 mounted thereon, so that it will not be too loose or too tight.

[0043] In the device of the utility model, the assembly and matching relationship of the various components involved, the spring 5, the insulating sheet 4, the wire 3 and the superconducting heating wire 2 are existing technologies or materials, and the relevant technical personnel can directly purchase or customize them from the market according to the required product models and specifications.

[0044] The electrical components mentioned in the text are all connected to an external main controller and 220V mains or industrial electricity, and the main controller can be a conventional known device such as a computer that plays a control role.

[0045] 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. Therefore, no matter from which point of view, the embodiment should be regarded as exemplary and non-restrictive. Any technician familiar with the technical field within the technical scope disclosed by the utility model, according to the technical scheme of the utility model and its utility model concept, shall be covered within the protection scope of the utility model.
