Description

Technical Field

[0001] The present invention relates to the field of magnetic therapy technology, in particular to a multi-point dense fine magnetic therapy device. Background Art

[0002] Current magnetic therapy devices are generally composed of a shell, a coil, and an iron core composed of magnetic needles. A magnetic field is generated by energizing the coil. The magnetic field at the needle tip of the magnetic needle is stronger, and the magnetic field between the magnetic needles is weaker, thereby creating a physiological difference in the human body and promoting blood circulation. The heating of the magnetic needles will reduce the strength of the magnetic field and burn the human body, so the heat dissipation of the magnetic needles is a problem that must be solved. The invention patent with patent number 202310762180.6 discloses a self-heating fine magnetic field device. A branch pipe is set between each two magnetic needles to extend into the device, and a fluid is passed through to dissipate heat and cool down. However, this method requires a larger space in the iron core, which reduces the efficiency of electromagnetic induction; the magnetic needles are easy to move relative to each other, which is not convenient for production and long-term use; the magnetic needles need to be electroplated with a layer of corrosion-resistant and wear-resistant electroplating film on the surface of the magnet. The surface of traditional magnetic needles is smooth and flat, which makes the fixation during the electroplating process more cumbersome.

[0003] Therefore, it is necessary to propose a new type of multi-point dense fine magnetic therapy device to solve the above problems, and to solve the problems that the heat dissipation structure of the traditional magnetic therapy device occupies a large space in the iron core, reduces the electromagnetic induction efficiency, the magnetic needle is easy to move relative to each other, is inconvenient to produce and use for a long time, and the electroplating process is relatively cumbersome. Summary of the Invention

[0004] The present invention provides a multi-point dense fine magnetic therapy device, which solves the problems of traditional magnetic therapy devices such as the heat dissipation structure occupying a large space in the iron core, reducing electromagnetic induction efficiency, easy relative movement of magnetic needles, inconvenient production and long-term use, and a relatively cumbersome electroplating process.

[0005] The technical problem solved by the present invention is achieved by adopting the following technical solutions: A multi-point dense fine magnetic therapy device, comprising: case; The bracket is arranged inside the shell and has an assembly hole that passes through the bracket from top to bottom; A coil, wherein the coil surrounds the periphery of the bracket; Magnetic needles are provided in plurality and are arranged in the assembly hole. The magnetic needles are provided with annular grooves surrounding the magnetic needles and perpendicular to the length direction of the magnetic needles. Adjacent annular grooves are filled with fixing structures for relatively fixing adjacent magnetic needles.

[0006] Furthermore, the fixing structure is provided with a plurality of through holes for accommodating the annular groove.

[0007] Furthermore, a convex edge whose thickness gradually increases in a direction away from the fixed structure is provided on the outer side of the fixed structure, and a slot for accommodating the convex edge is provided in the assembly hole.

[0008] Furthermore, the fixing member is distributed with a plurality of meshes, and the meshes surround the through holes, and the meshes enable the parts of the fixing structure other than the through holes to communicate with each other from top to bottom.

[0009] Furthermore, it also includes a heat dissipation device and a pump. A pipeline is provided in the fixed structure, and the pipeline is arranged around the through hole. The heat dissipation device is connected to both ends of the pipeline. The pump drives the fluid to circulate between the pipeline and the heat dissipation device.

[0010] Furthermore, the pipeline includes a plurality of annular tubes, each annular tube surrounds a through hole, and adjacent annular tubes are connected.

[0011] Furthermore, the fixing structure is glue.

[0012] Furthermore, the annular groove is located below the magnetic needle.

[0013] Furthermore, the annular grooves are on the same horizontal plane.

[0014] Furthermore, a needle head is provided at the top of the magnetic needle, and the needle head includes a frustum portion that gradually shrinks from bottom to top and a spherical crown portion located on the top of the frustum portion.

[0015] The present invention has the following beneficial effects: The present invention provides an annular groove surrounding the magnetic needle and perpendicular to its length, and fills adjacent annular grooves with a fixing structure for relatively fixing adjacent magnetic needles, thereby forming an iron core. The iron core is arranged in an assembly hole of a housing. The fixing structure occupies very little space in the iron core, has high electromagnetic induction efficiency, and the magnetic needles do not move relative to each other. The structure is stable during the production process, which is convenient for production and long-term use. The fixing structure can be provided with a pipe for circulating fluid, which also occupies a small space. The annular groove can provide a fixing position during electroplating of the magnetic needle, making the electroplating process relatively convenient. This solves the problems of traditional magnetic therapy devices in which the heat dissipation structure occupies a large space in the iron core, reduces electromagnetic induction efficiency, the magnetic needles are easily moved relative to each other, is inconvenient for production and long-term use, and the electroplating process is relatively cumbersome.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0034] Example 1, see Figures 1 to 5 , a multi-point dense fine magnetic therapy device, comprising: Shell 1; The bracket 11 is provided inside the housing 1 and has an assembly hole 12 extending therethrough. Coil 2, the coil 2 surrounds the outer periphery of the bracket 11; The magnetic needles 3 are provided in plurality and are arranged in the assembly hole 12. The magnetic needles 3 are provided with an annular groove 31 which surrounds the magnetic needles 3 and is perpendicular to the length direction of the magnetic needles 3. The adjacent annular grooves 31 are filled with a fixing structure 4 for relatively fixing the adjacent magnetic needles 3.

[0035] By providing an annular groove 31 on the magnetic needle 3 that surrounds the magnetic needle 3 and is perpendicular to the length direction of the magnetic needle 3, a fixing structure 4 for relatively fixing the adjacent magnetic needles 3 is filled between adjacent annular grooves 31, thereby forming an iron core. The iron core is arranged in the assembly hole 12 of the shell 1. The fixing structure 4 occupies a very small space in the iron core, has high electromagnetic induction efficiency, and the magnetic needles 3 will not move relative to each other. The structure is stable during the production process, which is convenient for production and long-term use. The fixing structure 4 can be provided with a pipeline for circulating fluid, which also occupies a small space. The annular groove 31 can provide a fixing position during the electroplating of the magnetic needle, and the fixing process of the electroplating is relatively convenient. This solves the problems of the heat dissipation structure of traditional magnetic therapy devices occupying a large space in the iron core, reducing the electromagnetic induction efficiency, the magnetic needles are prone to relative movement, which is inconvenient for production and long-term use, and the fixing process of the electroplating is relatively cumbersome.

[0036] The annular groove 31 is located at the lower part of the magnetic needle 3. This ensures that the magnetic needle closest to the human body obtains a stronger magnetic induction intensity.

[0037] The annular grooves 31 are on the same horizontal plane, which can make the fixing structure 4 simpler and more stable.

[0038] The top of the magnetic needle 3 is provided with a needle head 32, which includes a truncated cone portion 33 that gradually decreases from bottom to top and a spherical crown portion 34 located on the top of the truncated cone portion 33. The spherical crown portion 34 has a better sense of contact with the human body and avoids hurting the skin.

[0039] The fixing structure 4 is made of adhesive. During the production process, the adhesive is filled between adjacent annular grooves 31, creating a larger contact surface between the magnetic needles and the adhesive, resulting in greater stability, significantly reducing the chance of relative movement of the magnetic needles 3, and occupying less space. After production, the adhesive forms a strong fixing structure 4, providing strong support for the fixation of the magnetic needles 3.

[0040] Example 2, see Figures 6 to 8 , different from other embodiments, the fixing structure 4 is provided with a plurality of through holes 41 for accommodating the annular groove 31. The through holes 41 can make way for the annular groove 31, so that the magnetic needle can form a compact iron core and obtain a stable structure.

[0041] The outer side of the fixing structure 4 is provided with a convex edge 42 whose thickness gradually increases away from the fixing structure 4, and the assembly hole 12 is provided with a slot 13 for accommodating the convex edge 42. In this way, the convex edge 42 can be firmly embedded in the assembly hole 12, further enhancing the relative stability of the magnetic needle 3 and the bracket 11.

[0042] Preferably, the fixing structure 4 is made of elastic material, which makes it easier to insert the convex edge 42 into the slot 13 .

[0043] Example 3, see Figures 9 to 11 Unlike other embodiments, the fixing member 4 is provided with a plurality of mesh holes 44 surrounding the through-holes 41. These mesh holes 44 allow the portion of the fixing structure 4 other than the through-holes 41 to communicate vertically. During use, the mesh holes 44 provide both support and ventilation, separating adjacent magnetic needles 3 with minimal gaps while still providing sufficient heat dissipation.

[0044] Preferably, the fixing structure 4 is made of corrosion-resistant metal material, which has a stable structure and is corrosion-resistant and wear-resistant.

[0045] Example 4, see Figures 12 to 15 Unlike other embodiments, this embodiment further includes a heat sink and a pump. A pipe 43 is provided within the fixed structure 4, surrounding the through-hole 41. The heat sink is connected to both ends of the pipe 43, and the pump drives fluid to circulate between the pipe 43 and the heat sink. Pipe 43 provides heat dissipation while occupying a small space, ensuring a strong magnetic induction intensity at the magnetic needle closest to the human body.

[0046] Heat sinks and pumps are common components. This embodiment utilizes an air-cooled radiator, comprising heat exchange tubes, heat exchange fins, and a fan. Pipe 43 connects the two ends of the heat exchange tubes. The tubes and fins are made of copper, a material with high thermal conductivity. In this embodiment, the tubes are made of copper, and the fins are made of aluminum. The fins abut the outside of the tubes for heat exchange. The fan blows air over the fins, removing heat from the fins and cooling the fluid.

[0047] The pump is provided on the heat dissipation device or the pipe 43. The pump is an air pump or a liquid pump. The pump allows the fluid to circulate between the pipe 43 and the heat exchange tube. The fluid in this embodiment is pure water.

[0048] The pipe 43 includes several annular tubes 45, each of which surrounds a through hole 41, and adjacent annular tubes 45 are interconnected. The annular tubes 45 ensure that each magnetic needle 3 receives circumferential heat dissipation. Such a pipe 43 allows the fluid to flow over a wider range and quickly flow through the pipe 43, greatly improving heat dissipation efficiency and making heat dissipation more uniform.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
