[0042] In the description of the present application, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0043] In order to solve the technical problems in the prior art that the electromagnetic heating cover is relatively large in size, occupies more placement space, and the internal heating coil 4 is prone to shaking during operation or transportation; therefore, an embodiment of the utility model provides an electromagnetic heating cover.

[0044] The specific structure of an electromagnetic heating cover provided by an embodiment of the utility model is described in detail below. As shown in the accompanying drawings, the specific structure of the electromagnetic heating cover includes a mounting cover body 1, a support member 2, a heat insulation board 3, a heating coil body 4 and a pressing strip 5.

[0045] A heating cavity 11 is formed in the hollow of the installation cover 1. Specifically, the support member 2, the heat insulation board 3, the heating coil 4 and the pressing strip 5 of the embodiment of the utility model are all built into the heating cavity 11, wherein the heating coil 4 generates heat in the heating cavity 11, thereby providing a large amount of heat. When transporting the entire electromagnetic heating cover, since the support member 2, the heat insulation board 3, the heating coil 4 and the pressing strip 5 are all arranged in the heating cavity 11 in the installation cover 1, this arrangement facilitates the direct transportation of the entire electromagnetic heating cover.

[0046] At least two support members 2 are provided, and the two support members 2 are respectively provided on two opposite side walls of the heating chamber 11 .

[0047] Specifically, the heating chamber 11 has two inner walls facing each other, and the side surfaces of the two support members 2 are respectively in contact with the two inner walls. The two support members 2 are used to support the heat insulation board 3 and the pressing strip 5, so as to prevent the heat insulation board 3 and the pressing strip 5 from shaking violently in the heating chamber 11, thereby improving the stability of the heat insulation board 3 and the pressing strip 5, and there is no need to set other supporting components, thereby further reducing the volume occupancy rate.

[0048] It can be understood that the length of the two support members 2 in the embodiment of the utility model is equal to or less than the length of the heating chamber 11, and is thus arranged so that the support members 2 can be assembled in the heating chamber.

[0049] It should be noted that when the entire electromagnetic heating cover is placed on a table or the ground, it is supported by the bottom surfaces of the two support members 2. Since the bottom surface areas of the two support members 2 are small, a large amount of heat generated during operation can be avoided from forming a large area of ​​thermal contact with the table or the ground.

[0050] There are multiple heat insulation boards 3 , and the multiple heat insulation boards 3 are spliced ​​with each other. Each heat insulation board 3 can be detachably arranged on the support member 2 .

[0051] Specifically, since the heating coil 4 generates a large amount of high-temperature heat during operation, in order to avoid more heat loss, multiple insulation boards 3 are provided to reduce heat transfer and prevent heat conduction, thereby achieving the effect of heat insulation; specifically, since the multiple insulation boards 3 have a lower thermal conductivity, the heat conduction process will be hindered, thereby reducing the heat loss caused by heat conduction to the other side, thereby effectively preventing the conduction of heat, and the multiple insulation boards 3 can also play an isolation role, for example, preventing other objects from directly contacting the heating coil 4.

[0052] It should be noted that after multiple insulation boards 3 are spliced ​​together, the influence of the thermal bridge effect can be further reduced, preventing a large amount of heat from being conducted in the structure.

[0053] It can be understood that the multiple insulation boards 3 in the embodiment of the utility model are all microcrystalline glass boards or ceramic insulation boards 3, and the specific type is not limited here.

[0054] The heating coil 4 is fixedly disposed in the heating cavity 11 and disposed on the top surfaces of the plurality of heat insulation boards 3 for generating heat.

[0055] It should be noted that, by arranging a power source externally, the power source is electrically connected to the heating coil 4, and by controlling the output power and frequency of the power source, the heating coil 4 generates an alternating current.

[0056] Specifically, when the power supply outputs power and frequency, the induced current density in the heating coil 4 can be controlled, thereby controlling the heating of the heating coil 4. Under the action of the electromagnetic field, the current in the heating coil 4 will cause an electromagnetic thermal effect inside it. Since the heating coil 4 forms a circular magnetic field and interacts with the source magnetic field, energy is converted into heat energy. At this time, the heating coil 4 has a heating effect.

[0057] It can be understood that the heating coil body 4 of the embodiment of the utility model is a coil made of materials such as copper or aluminum, and the specific material is not limited here.

[0058] There are multiple pressing strips 5 , and both ends of each pressing strip 5 are detachably connected to the two supporting members 2 for pressing the heating coil 4 .

[0059] Specifically, a plurality of pressing strips 5 are arranged along the length of the heating chamber, and the bottom surfaces of the plurality of pressing strips 5 are pressed on the heating coil 4 at the same time, so that the heating coil 4 can always be fixed in the current installation position during the heating process or during transportation, thereby improving the stability of the heating coil 4. Since the pressing strips 5 are detachable, when taking out the heating coil 4, it is only necessary to remove the plurality of pressing strips 5 from the support member 2, so that the pressing strips 5 cannot press the heating coil 4.

[0060] It can be understood that each pressing strip 5 is detachably arranged on the supporting member 2 by means of snaps, threads or bolts, and the specific method is not limited here.

[0061] It should be noted that the multiple pressing strips 5 in the embodiment of the utility model are all synthetic stones. Synthetic stones have high strength and stability and can withstand the tension and pressure of the heating coil. Therefore, when pressing the heating coil 4, it can avoid the problem of displacement that may be caused during the heat transfer process.

[0062] To sum up the above, by setting two support members 2 in the installation cover body 1, multiple pressing strips 5 are detachably arranged on the support members 2 for pressing the heating coil 4, and there is no need to set additional fixing components, thereby further reducing the volume occupancy rate of the entire electromagnetic heating cover; since the multiple insulation boards 3 and the multiple pressing strips 5 are detachably arranged, when the heating coil 4 needs to be disassembled, repaired or replaced, it is only necessary to disassemble and remove each insulation board 3 and each pressing strip 5, and then the heating coil 4 can be taken out. The overall structure is simple and the disassembly process is relatively convenient.

[0063] In some specific embodiments, each support member 2 is provided with a support portion 21 , and each heat insulation board 3 is disposed on the support portion 21 of each support member 2 .

[0064] Specifically, it can be understood that each support portion 21 is a protrusion provided on the support member 2, and the heights of the two support portions 21 are the same, so when each heat insulation board 3 is provided on the top surface of the support portion 21, it can maintain a parallel swing direction, which is used to prevent each heat insulation board 3 from being easily separated. In addition, it should be noted that when the electromagnetic heating cover is placed, it is supported on the ground or the table by the bottom surfaces of the two support portions 21.

[0065] In a further embodiment, the electromagnetic heating cover also includes a first locking piece; a plurality of first locking holes are passed through the support member 2 or the support portion 21, and a first fixing hole is opened on the side of each insulation board 3. The first locking piece can be removably inserted into the first locking hole and a fixing hole to fix each insulation board 3.

[0066] Specifically, in order to improve the stability of each insulation board 3 and the convenience during disassembly; for this reason, when assembling each insulation board 3, it is only necessary to move the length of the upper edge of the support member 2 of each insulation board 3 until its first fixing hole can be connected with the first locking hole on the support member 2 or the support portion 21 respectively, and then each first locking member is inserted into the first locking hole and the first fixing hole respectively at the same time to fix each insulation board 3, thereby improving the convenience of each insulation board 3 during assembly; conversely, when disassembling each insulation board 3, it is only necessary to remove the insulation board 3 by removing the first locking member from the first locking hole and the first fixing hole.

[0067] It should be noted that if the first locking hole is penetrated on the support member 2, a through hole corresponding to the first locking hole is penetrated on the inner side wall of the support member 2 abutting against the mounting cover body 1, so that the first locking member can be inserted into the first locking hole through the through hole from the outside.

[0068] In some specific embodiments, openings 12 communicating with the heating chamber 11 are formed on both sides of the mounting cover 1 , and sealing panels 13 are detachably provided in the openings 12 .

[0069] Specifically, in order to facilitate the replacement or maintenance of the components inside the installation cover 1, openings 12 are set on the opposite sides of the installation cover 1, and two sealing panels 13 are used to open or close the openings 12 on both sides respectively. This arrangement makes it easy for maintenance personnel to remove the sealing panels 13 from the openings 12, disassemble, repair and replace the internal components, and when the maintenance is completed, the sealing panels 13 can be reassembled in the openings 12.

[0070] Specifically, the electromagnetic heating cover also includes a second locking piece; a second locking hole 111 is opened through the cavity wall of the heating cavity 11, and a second fixing hole 131 is opened on the side of the sealing plate 13 opposite to the cavity wall of the heating cavity 11, and the second locking piece is detachably inserted into the second locking hole 111 and the second fixing hole 131 at the same time to fix the sealing plate 13.

[0071] Specifically, when assembling the sealing plate 13, it is only necessary to connect the second fixing hole 131 of the sealing plate 13 to the corresponding second locking hole 111 on the cavity wall of the heat-generating cavity 11, and then insert the second locking piece into the second locking hole 111 and the second fixing hole 131 at the same time to fix the sealing plate 13. This arrangement improves the convenience of assembling the sealing plate 13; conversely, when disassembling the sealing plate 13, it is only necessary to remove the second locking piece from the second locking hole 111 and the second fixing hole 131 to remove the sealing plate 13.

[0072] In a further embodiment, buckling grooves 132 are recessed on both sides of the sealing plate 13 , and buckling portions 22 for buckling in the buckling grooves 132 are disposed on the two support members 2 .

[0073] Specifically, the snap-fitting portion 22 extends along the length of the support member 2. When the sealing plate 13 is assembled in the opening 12, the snap-fitting portion 22 is consistent with the snap-fitting groove 132 in height. Therefore, the snap-fitting portion 22 is snapped in the snap-fitting groove 132, which effectively prevents the sealing plate 13 from moving up and down or swinging in the opening 12, thereby improving the stability and reliability of the entire sealing plate 13.

[0074] It is understandable that the buckling portion 22 of the embodiment of the present invention has an elastic property, so when the sealing plate 13 is assembled in the opening 12 , the buckling portion 22 can be automatically buckled in the buckling groove 132 .

[0075] In some specific embodiments, a plurality of blowing ports which are all connected to the heating chamber 1 are provided on the mounting cover body 1, and a blower 6 can be detachably provided in each blowing port.

[0076] Specifically, since a large amount of heat is generated during the heating process, if the heat cannot be dissipated in time, the equipment will overheat, affecting its service life and performance. For this reason, a plurality of blowers 6 are detachably arranged on the top of the installation cover 1. When heat dissipation and cooling are required, a plurality of blowers 6 are operated simultaneously to transfer heat to the surface of the radiator, and then dissipate the heat into the external air by convection or conduction, thereby effectively reducing the temperature inside the installation cover 1. This product can be maintained within a safe operating temperature range. At the same time, the blower 6 can also eliminate potential internal heat accumulation points, prevent local overheating or hot spots, and ensure the stability and reliability of the entire electromagnetic heating cover during operation.

[0077] In a further embodiment, a mounting frame 61 is provided in each air outlet, and each blower 6 is detachably disposed on the mounting frame 61 .

[0078] Specifically, a mounting opening that passes through the thickness of the mounting frame 61 is formed. The mounting frame 61 can be detachably arranged in the blowing port by means of threads or snaps. The hair dryer 6 can also be detachably arranged on the mounting frame 61 by means of threads or snaps. When the hair dryer 6 is blowing air, it can discharge the heat from the heating chamber to the outside.

[0079] In some specific embodiments, a plurality of heat dissipation holes 14 connected to the heat-generating cavity 11 are provided on the installation cover 1. The high-temperature heat in the installation cover 1 is conducted to the external environment through the plurality of heat dissipation holes 14, thereby effectively reducing the internal temperature. The heat dissipation capacity is further improved by cooperating with the hair dryer 6 through the plurality of heat dissipation holes 14.

[0080] In a further embodiment, an airflow guide 15 for guiding the gas to be discharged downward is provided in each heat dissipation hole 14, whereby the internal hot air flow is more concentrated and flows downward rapidly, thereby accelerating the heat dissipation process and preventing the hot air flow from flowing to other external components.

[0081] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
