Description

Technical Field

[0001] This utility model relates to the field of induction heating equipment, specifically an induction heating device that facilitates heat dissipation. Background Technology

[0002] Induction heating equipment is a device that uses the principle of electromagnetic induction to heat objects. It generates high-frequency current in conductive materials (such as metals), thereby generating heat inside the material to achieve the purpose of heating. This heating method has many advantages, such as fast heating speed, precise temperature control, energy saving, and no pollution, and therefore it has been widely used in many industrial fields.

[0003] Existing induction heating equipment usually has heat dissipation holes on both sides for natural heat dissipation. However, when used in factories, there is a lot of dust. Filters are installed inside the heat dissipation holes to filter the dust, but the filters are not very effective at filtering dust. Some dust can enter the induction heating equipment through the heat dissipation holes. Dust falling on the control board can easily cause short circuits. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an induction heating device that facilitates heat dissipation, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an induction heating device for easy heat dissipation, comprising an induction heating device body, heat dissipation holes on both sides of the induction heating device body, and an air intake fan inside the induction heating device body. A filter assembly is installed inside the heat dissipation holes. The filter assembly includes a limiting plate, a fixing frame, and filter cotton. A fixing frame is fixed to one side of the limiting plate, and filter cotton is installed inside the fixing frame. Multiple sets of air holes are opened on one side of the limiting plate. Extrusion assemblies are provided on both sides of the induction heating device body. Each extrusion assembly includes an extrusion block, a fixing block, a fixing rod, and a spring. Multiple sets of extrusion blocks are movably installed on both sides of the limiting plate. Multiple sets of fixing blocks are fixed to both sides of the induction heating device body, and a fixing rod is fixed to one side of each fixing block. A spring is sleeved on the outer wall of the fixing rod. A limiting hole is opened on one side of the extrusion block, and the inner wall of the limiting hole fits against the outer wall of the fixing rod.

[0006] Preferably, the intake fan draws in outside air into the induction heating device to dissipate heat. The filter cotton filters dust, preventing it from adhering to the circuit board and causing a short circuit. The compression assembly secures the filter assembly, and the spring provides elasticity to the compression block, ensuring a tight fit between the limiting plate and the outer wall of the induction heating device. This prevents dust from entering the induction heating device through the connection between the limiting plate and the induction heating device.

[0007] The present invention is further configured such that the limiting plate has two inclined surfaces on both sides, and the extrusion block has one inclined surface on one side.

[0008] Preferably, the inclined extrusion block can easily extrude the limiting plate, and the extrusion block limits the limiting plate to prevent the limiting plate from moving easily.

[0009] The present invention is further configured such that a connecting rod is fixed between the multiple sets of extrusion blocks.

[0010] Preferably, the connecting rods can be used to easily connect multiple sets of extrusion blocks, so that when one set of extrusion blocks moves, the rest of the extrusion blocks will also move together.

[0011] The present invention is further configured such that multiple sets of horizontal plates are fixed to the inner wall of the limiting plate, and the horizontal plates are in close contact with the filter cotton.

[0012] Preferably, the horizontal plate can prevent the gas from blowing the filter cotton into deformation.

[0013] The present invention is further configured such that sealing rings are fixed on both sides of the induction heating device body, and a groove is provided on one side of the limiting plate.

[0014] Preferably, by using a sealing ring that engages with the groove, when the limiting plate is in contact with the body of the induction heating device, the sealing ring enters the interior of the groove, thus preventing backflow gas from entering the interior of the induction heating device body from the connection between the body of the induction heating device and the limiting plate.

[0015] The present invention is further configured such that the inner wall of the air hole is inclined.

[0016] Preferably, the inclined arrangement of the air holes can reduce the flow rate of gas entering the body of the induction heating device, thereby slowing down the airflow and causing dust to adhere only to one side of the filter cotton surface.

[0017] The present invention is further configured such that a screw is movably installed on one side of the induction heating device body, and a rectangular rod is fixed at the end of the screw. A rotating rod is fixed at the end of the rectangular rod, and a gear is sleeved on the outer wall of the rectangular rod. A first toothed rod and a second toothed rod are movably installed on both sides of the induction heating device body. The first toothed rod is fixed to a set of the fixed blocks, and the second toothed rod is fixed to another set of the fixed blocks. A rectangular hole is opened inside the gear.

[0018] Preferably, when the filter assembly needs to be installed or removed, the rotating rod is rotated, which drives the rectangular rod to rotate. When the rectangular rod rotates, it drives the screw to rotate. The screw is threadedly connected to the body of the induction heating device. The rectangular rod drives the gear to rotate. When the gear rotates, it drives the first and second gears meshing with it to move to both sides, so that the extrusion rods located on both sides of the limiting plate slide on the outer wall of the fixed rod. Then the filter assembly is installed inside the heat dissipation hole. One person can install the filter assembly, improving the efficiency of installation and removal.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model is equipped with a filter assembly, an air intake fan, and a compression assembly. The air intake fan draws in external air into the induction heating device to dissipate heat. The filter cotton filters dust, preventing it from adhering to the circuit board and causing a short circuit. The compression assembly secures the filter assembly, and the spring provides elasticity to the compression block, ensuring a tight fit between the limiting plate and the outer wall of the induction heating device, preventing dust from entering the device through the connection between the limiting plate and the induction heating device.

[0021] 2. This utility model is equipped with a rotating rod, gear, rectangular rod, first toothed rod and second toothed rod. With the gear and rotating rod, when it is necessary to disassemble the filter assembly, rotating the rotating rod will cause the squeezing blocks on both sides of the filter assembly to slide to both sides, thereby facilitating the disassembly and cleaning of the filter assembly.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1: Please refer to Figures 1-5The device includes an induction heating device body 1, with heat dissipation holes 5 on both sides. An air intake fan 6 is installed inside the induction heating device body 1. A filter assembly 2 is installed inside the heat dissipation holes 5. The filter assembly 2 includes a limiting plate 21, a fixing frame 22, and filter cotton 24. A fixing frame 22 is fixed to one side of the limiting plate 21, and filter cotton 24 is installed inside the fixing frame 22. Multiple sets of air holes 26 are opened on one side of the limiting plate 21. Extrusion assemblies 3 are installed on both sides of the induction heating device body 1. The extrusion assembly 3 includes extrusion blocks 31, fixing blocks 4, fixing rods 41, and springs 42. Multiple sets of extrusion blocks 31 are movably installed on both sides of the limiting plate 21. Multiple sets of fixing blocks 4 are fixed to both sides of the induction heating device body 1, and a fixing rod 41 is fixed to one side of each fixing block 4. The outer wall of the fixing rod 41... A spring 42 is fitted onto the connecting rod 32, which pushes the connecting rod 32 to both sides. The connecting rod 32 moves the pressing block 31 fixed to it. The pressing block 31 slides on the outer wall of the fixing rod 41 and presses the spring 42. Then, the fixed frame 22 is installed into the inner wall of the heat dissipation hole 5. A limit hole 33 is opened on one side of the pressing block 31, and the inner wall of the limit hole 33 is in contact with the outer wall of the fixing rod 41, so that the limit plate 21 contacts the induction heating device body 1. At this time, the sealing ring 7 enters the inner wall of the groove 25. Then, the connecting rod 32 is released, and the pressing block 31 will be driven to reset under the action of the spring 42. Since one side of the pressing block 31 and both sides of the limit plate 21 are inclined, the spring 42 will drive the pressing block 31 to press the limit plate 21, so that the limit plate 21 is tightly attached to the induction heating device body 1.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 and Figure 5 The limiting plate 21 has beveled sides on both sides and the pressing block 31 has beveled side on one side. The beveled pressing block 31 can easily press the limiting plate 21 and limit the limiting plate to prevent the limiting plate 21 from moving easily.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 A connecting rod 32 is fixed between multiple sets of extrusion blocks 31. The connecting rod 32 can be used to easily connect multiple sets of extrusion blocks 31, so that when one set of extrusion blocks 31 moves, the other extrusion blocks 31 will also move together.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The inner wall of the limiting plate 21 is fixed with multiple sets of horizontal plates 23, and the horizontal plates 23 are in close contact with the filter cotton 24. The horizontal plates 23 can prevent the gas from blowing the filter cotton 24 into deformation.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 and Figure 3The induction heating device body 1 is fixed with sealing rings 7 on both sides, and the limiting plate 21 has a groove 25 on one side. The sealing rings 7 cooperate with the groove 25. When the limiting plate 21 is in contact with the induction heating device body 1, the sealing rings 7 enter the interior of the groove 25, which can prevent the backflow gas from entering the interior of the induction heating device body 1 from the connection between the induction heating device body 1 and the limiting plate 21.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 1 The inner wall of the air hole 26 is inclined. The inclined air hole 26 can reduce the flow rate of gas entering the body of the induction heating device 1, thereby slowing down the airflow and allowing dust to adhere only to one side of the surface of the filter cotton 24.

[0041] Example 2: Please refer to Figures 6-9 A screw 13 is movably mounted on one side of the induction heating device body 1, and a rectangular rod 12 is fixed to the end of the screw 13. A rotating rod 11 is fixed to the end of the rectangular rod 12, and a gear 10 is sleeved on the outer wall of the rectangular rod 12. A first gear 8 and a second gear 9 are movably mounted on both sides of the induction heating device body 1. The first gear 8 is fixed to a set of fixing blocks 4, and the second gear 9 is fixed to another set of fixing blocks 4. A rectangular hole 14 is opened inside the gear 10. When it is necessary to install or remove the filter assembly, the rotating rod 11 is rotated. The rotating rod 11 drives the rectangular rod 12 to rotate. When the rectangular rod 12 rotates, it drives the screw 13 to rotate. The screw 13 is threadedly connected to the body 1 of the induction heating device. The rectangular rod 12 drives the gear 10 to rotate. When the gear 10 rotates, it drives the first toothed rod 8 and the second toothed rod 9 that mesh with it to move to both sides, so that the pressing rods 3 located on both sides of the limiting plate 21 slide on the outer wall of the fixed rod 41. Then the filter assembly 2 is installed inside the heat dissipation hole 5. One person can install the filter assembly 2, which improves the efficiency of installation and disassembly.

[0042] In practical operation, when the filter assembly 2 needs to be installed, the connecting rod 32 is pushed to both sides. The connecting rod 32 drives the pressing block 31 fixed to it to move. The pressing block 31 slides on the outer wall of the fixing rod 41 and the pressing block 31 will press the spring 42. Then, the fixed frame 22 is installed into the inner wall of the heat dissipation hole 5, so that the limiting plate 21 contacts the induction heating device body 1. At this time, the sealing ring 7 enters the inner wall of the groove 25. Then, the connecting rod 32 is released. Under the action of the spring 42, the pressing block 31 will be reset. Since one side of the pressing block 31 and both sides of the limiting plate 21 are inclined, the spring 42 will drive the pressing block 31 to press the limiting plate 21, so that the limiting plate 21 is tightly attached to the induction heating device body 1. At this time, the spring 42 is in a compressed state. The spring 42 can continuously give the pressing block 31 a pressing force. Then, the air intake fan 6 works to draw the outside air into the interior of the induction heating device body 1. The filter cotton 24 can filter the dust in the air.

[0043] When the filter cotton needs to be cleaned, pull the squeezing blocks 31 to both sides to remove the filter assembly and clean the filter cotton.
