Description

A multi-point dense fine magnetic therapy device with fluid heat dissipation Technical Field

[0001] This invention relates to the field of magnetotherapy technology, and in particular to a multi-point dense fine magnetotherapy device with fluid heat dissipation. Background Technology

[0002] Current magnetic therapy devices generally consist of a shell, coils, and an iron core made of magnetic needles. By energizing the coils, a magnetic field is generated; the magnetic field is stronger at the needle tips and weaker between the needles, creating a physiological difference that promotes blood circulation. The heat generated by the coils and needles reduces the magnetic field strength, making heat dissipation a crucial issue. Patent No. 202310762180.6 discloses a self-cooling fine magnetic field device that uses a branch pipe inserted between every two needles to allow fluid to flow and cool the device. Patent No. 202310762095.X discloses a frameless multi-point magnetic field device where windings are arranged around the periphery of a conduit, which in turn surrounds multiple magnetic needles. A pump drives fluid to flow through the conduit, allowing the fluid to absorb the heat generated by the windings and needles.

[0003] However, the heat dissipation structure described above requires a large space in the iron core, reduces electromagnetic induction efficiency, and fails to provide a stable support for the magnetic needle.

[0004] Therefore, it is necessary to propose a novel multi-point dense fine magnetic therapy device with fluid heat dissipation to solve the above problems, thereby addressing the issues that the heat dissipation structure of traditional magnetic therapy devices requires a large space in the iron core, reduces electromagnetic induction efficiency, and fails to provide stable support for the magnetic needles. Summary of the Invention

[0005] This invention provides a multi-point dense fine magnetic therapy device with fluid heat dissipation, which solves the problems of traditional magnetic therapy devices requiring a large space in the iron core for heat dissipation structure, reducing electromagnetic induction efficiency, and failing to provide stable support for the magnetic needles.

[0006] The technical problem solved by this invention is achieved by the following technical solution:

[0007] A multi-point dense fine magnetic therapy device with fluid cooling includes:

[0008] The skeleton includes a hollow support and an upper plate and a lower plate located at the top and bottom of the support, and the bottom surface of the lower plate is provided with a lower plate spiral groove;

[0009] A coil, the coil surrounding the periphery of the bracket;

[0010] A magnetic needle, wherein several magnetic needles are provided and disposed within a support;

[0011] The chassis has a spiral groove on its top surface. The chassis is fixedly connected to the lower plate. The spiral groove of the lower plate and the spiral groove of the chassis are combined to form a spiral fluid pipe.

[0012] Furthermore, it also includes a spiral tube embedded in and conforming to the fluid pipe, wherein the spiral tube is made of a thermally conductive material.

[0013] Furthermore, it also includes a heat-conducting plate with a spiral channel. The heat-conducting plate is held between the bottom surface of the lower plate and the top surface of the chassis. The spiral channel is embedded in and fits the fluid pipe. The heat-conducting plate and the spiral channel are made of heat-conducting material.

[0014] Furthermore, it also includes a pump, a water tank, heat sinks, and conduits. The heat sinks are installed on the water tank to dissipate heat from the water tank. The pump connects the water tank to the conduit, and the conduit connects to the fluid pipeline. The fluid pipeline, pump, water tank, and conduit together form a circulating heat dissipation system.

[0015] Furthermore, the lower plate is provided with a notch to expose the outer end of the chassis spiral groove, and the connection between the conduit and the outer end of the fluid pipe is provided with a limiting member that fits into the notch;

[0016] The bottom of the limiting member is provided with an external insertion pipe that communicates with the conduit. The external insertion pipe is made of elastic material and is interference-fitted with the outer end of the fluid pipe.

[0017] Furthermore, the chassis is provided with a through-hole, one end of the fluid pipe leads to the outside of the chassis, and the other end of the fluid pipe leads to the through-hole.

[0018] Furthermore, the lower plate is provided with a through hole penetrating the top and bottom surfaces of the lower plate, the through hole exposing the inner end of the through hole and the spiral groove of the lower plate, and the exposed part forms a step.

[0019] Furthermore, it also includes a connecting element, which is embedded in the step to fill the step, and the connecting element connects the inner end of the fluid conduit to the through hole.

[0020] Furthermore, the end of the conduit is provided with an L-shaped inner insertion tube, which is made of elastic material and is inserted into the through hole for interference fit with the connecting member.

[0021] Furthermore, the connecting member is basin-shaped and includes the bottom of the magnetic needle, and the connecting member is made of a thermally conductive material.

[0022] The beneficial effects of this invention are:

[0023] This invention addresses the problems of traditional magnetic therapy devices by creating a spiral groove on the bottom surface of the lower plate of the frame, surrounding the coil around the perimeter of the support, placing several magnetic needles within the support, and adding a base with a spiral groove on its top surface. The base is fixedly connected to the lower plate, and the spiral grooves of the lower plate and the base form a spiral fluid channel. During use, the fluid channel is connected to a fluid source, allowing the fluid to cool the lower plate of the frame. Heat absorbed by the lower plate from the magnetic needles and coils is transferred to the fluid for heat dissipation. This design eliminates the need for a core, reduces the frame's volume, ensures electromagnetic induction strength, and provides stable support for the magnetic needles. The spiral shape of the fluid channel ensures complete and even coverage of the lower plate, resulting in faster and more uniform heat dissipation. This solves the problems of traditional magnetic therapy devices requiring a large core space for heat dissipation, reducing electromagnetic induction efficiency, and failing to provide stable support for the magnetic needles.

[0040] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Example 1, referring to Figures 1 to 7, a multi-point dense fine magnetic therapy device for fluid heat dissipation includes:

[0042] The frame 1 includes a hollow support 10 and an upper plate 11 and a lower plate 12 located at the top and bottom of the support 10. The bottom surface of the lower plate 12 is provided with a lower plate spiral groove 13.

[0043] Coil 2, the coil 2 surrounding the periphery of the bracket 10;

[0044] Magnetic needle 3, wherein a plurality of magnetic needles 3 are provided and disposed within the bracket 10;

[0045] The chassis 4 has a chassis spiral groove 40 on its top surface. The chassis 4 is fixedly connected to the lower plate 12. The lower plate spiral groove 13 and the chassis spiral groove 40 are combined vertically to form a spiral fluid pipe 5.

[0046] This patent addresses the issues of traditional magnetic therapy devices by creating a spiral groove 13 on the bottom surface of the lower plate 12 of the frame 1, surrounding the coil 2 around the periphery of the support 10, placing several magnetic needles 3 within the support 10, and adding a base 4 with a spiral groove 40 on its top surface. The base 4 is fixedly connected to the lower plate 12. The spiral groove 13 and the spiral groove 40 together form a spiral fluid channel 5. In use, the fluid channel 5 is connected to a fluid source, which cools the lower plate 12 of the frame 1. The heat absorbed by the lower plate 12 from the magnetic needles 3 and coil 2 is transferred to the fluid through the fluid channel 5 for heat dissipation. This design eliminates the need for a core, reduces the frame's volume, ensures electromagnetic induction strength, and provides stable support for the magnetic needles. The spiral shape of the fluid channel 5 allows for complete and even coverage of the lower plate 12, resulting in faster and more uniform heat dissipation. This technology solves the problems of traditional magnetic therapy devices requiring a large core space for heat dissipation, reducing electromagnetic induction efficiency, and failing to provide stable support for the magnetic needles.

[0047] Preferably, both the frame 1 and the base 4 are made of thermally conductive materials, which can quickly absorb the heat from the coil 2 and the magnetic needle 3 and quickly transfer the heat to the fluid. The frame 1 and the base 4 can be pressed against each other to achieve a seal at the edge of the fluid pipe 5, or a sealing gasket can be placed between the frame 1 and the base 4 around the edge of the fluid pipe 5 to seal the fluid pipe 5.

[0048] The fluid may be insulating oil, pure water, or fluorinated liquid.

[0049] The chassis 4 is provided with a through-hole 41. One end of the fluid pipe 5 leads to the outside of the chassis 4, and the other end of the fluid pipe 5 leads to the through-hole 41. This allows the fluid to flow to the outside more conveniently and also facilitates disassembly and assembly.

[0050] The lower plate 12 is provided with a through hole 15 penetrating the top and bottom surfaces of the lower plate 12. The opening 41 exposes the inner end of the through hole 15 and the spiral groove 13 of the lower plate, and the exposed part forms a step 42. In use, the connecting conduit can be connected to the fluid pipe 5 from the opening 41, and then led to the outside through the through hole 15. This facilitates the conduit to be led out from the top surface of the lower plate 12, avoids the conduit occupying the space of the lower plate 12 and the chassis 4, and can further cool the coil.

[0051] Example 2, referring to Figure 8, differs from other examples in that it also includes a spiral tube 6 embedded within and fitted to the fluid pipe 5. The spiral tube 6 is made of a heat-conducting material. In use, the spiral tube 6 is placed into the spiral groove 13 of the lower plate, and then the base plate 4 is covered and secured; or the spiral tube 6 is placed into the spiral groove 40 of the base plate, and the lower plate 12 is covered and secured. The spiral tube 6 reduces the sealing requirements between the frame 1 and the base plate 4, making it safer.

[0052] Example 3, referring to Figure 9, differs from other examples in that it also includes a heat-conducting plate 7. The heat-conducting plate 7 has a spiral channel 70. The heat-conducting plate 7 is held between the bottom surface of the lower plate 12 and the top surface of the chassis 4. The spiral channel 70 is embedded in and fits snugly against the fluid pipe 5. Both the heat-conducting plate 7 and the spiral channel 70 are made of heat-conducting material. In use, the spiral channel 70 is placed into the spiral groove 13 of the lower plate, and then the chassis 4 is covered and secured; or the spiral channel 70 is placed into the spiral groove 40 of the chassis, and the lower plate 12 is covered and secured. The heat-conducting plate 7 is held between the bottom surface of the lower plate 12 and the top surface of the chassis 4. The spiral channel 70 achieves the technical effect of the spiral tube 6 in Example 2, namely, it reduces the sealing requirements between the frame 1 and the chassis 4, making it safer. The heat-conducting plate 7 can further dissipate heat from parts other than the fluid pipe 5.

[0053] Example 4, as shown in Figure 10, differs from other examples in that it also includes a pump 8, a water tank 80, a heat sink 81, and a conduit 82. The heat sink 81 is mounted on the water tank 80 to dissipate heat from the water tank 80. The pump 8 connects the water tank 80 to the conduit 82, and the conduit 82 connects to the fluid pipe 5. The fluid pipe 5, pump 8, water tank 80, and conduit 82 together form a circulating heat dissipation system. In use, the pump 8 is started, drawing the fluid from the water tank 80 into the fluid pipe 5. The fluid then flows from the fluid pipe 5 back into the water tank 80 through the conduit 82. During this process, the heat sink 81 cools the water tank 80, thereby circulating heat dissipation for the coil 2 and the magnetic needle 3, which can accelerate the heat dissipation efficiency.

[0054] The lower plate 12 is provided with a notch 14 that exposes the outer end of the chassis spiral groove 40, and the conduit 82 is provided with a limiting member 83 that fits into the notch 14 at the connection between it and the outer end of the fluid pipe 5.

[0055] The bottom of the limiting member 83 is provided with an external insertion tube 84 that communicates with the conduit 82. The external insertion tube 84 is made of elastic material and is interference-fitted with the outer end of the fluid pipe 5. In use, the external insertion tube 84 is inserted into the outer end of the fluid pipe 5, and the limiting member 83 is embedded in the notch 14, thereby reinforcing the connection between the conduit 82 and the fluid pipe 5.

[0056] It also includes a connecting member 9, which is embedded in the step 42 to fill the step 42, and the connecting member 9 connects the inner end of the fluid pipe 5 to the through hole 15. The connecting member 9 can fill the space of the step 42, making it more aesthetically pleasing, less prone to dust accumulation, and more durable.

[0057] The end of the conduit 82 is provided with an L-shaped inner insertion tube 85. The inner insertion tube 85 is made of elastic material. After being inserted into the through hole 15, the inner insertion tube 85 is press-fitted with the connecting member 9. The L-shaped inner insertion tube 85 allows the conduit 82 to extend along the top surface of the lower plate 12 and lead to the lower plate spiral groove 13 located on the bottom surface of the lower plate 12. After being inserted into the through hole 15, the inner insertion tube 85 is press-fitted with the connecting member 9, ensuring a stable connection.

[0058] In Example 5, referring to Figure 11, unlike other examples, the connecting member 9 is basin-shaped and includes the bottom of the magnetic needle 3. The connecting member 9 is made of a thermally conductive material. Thus, the connecting member 9 not only connects the conduit 82 and the fluid pipe 5, but also further dissipates heat and cools the magnetic needle 3.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
