Description

Technical Field

[0001] The invention relates to the field of magnetic therapy equipment, and in particular to a cooling structure of a magnetic therapy head. Background Art

[0002] Magnetic therapy is based on Faraday's law of electromagnetic induction. The magnetic induction coil generates an electric field through a pulsed current. Whenever the high-voltage energy storage capacitor group is discharged through the action of the control system, the pulse of the current stimulates the coil to produce a strong, rapidly changing pulsed magnetic field that can penetrate soft tissue and bones and reach deep neural structures. The output end of the magnetic therapy device often uses a magnetic therapy head to act on acupuncture points and nerves. When the magnetic therapy head is working, the coil inside it tends to heat up. The heated coil affects the stability of the magnetic field output and reduces the output magnetic field strength, resulting in energy waste.

[0003] The cooling of the existing magnetic therapy equipment can be carried out by air cooling or liquid cooling. The cooling effect of air cooling is limited and is easily accompanied by noise. Liquid cooling has the characteristics of fast cooling and low noise. The existing magnetic therapy heads are all directly cooled by the magnetic disk inside the magnetic therapy head, and the electronic components inside the magnetic therapy head are also cooled. The cooling liquid injected into the magnetic therapy head is prone to low utilization. The cooling liquid is directly discharged without sufficient contact with the magnetic therapy head, resulting in heat accumulation at the lower end of the magnetic coil disk inside the magnetic therapy head or heat accumulation at the upper end of the magnetic coil disk, thereby affecting the magnetic field strength output by the magnetic coil disk and causing energy waste. Therefore, a cooling structure of a magnetic therapy head is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that insufficient contact between the heat source and the coolant inside the magnetic therapy head leads to poor coolant utilization, thereby proposing a cooling structure for the magnetic therapy head.

[0040] Reference Figures 1-5 , the present invention also provides a cooling structure for a magnetic therapy head, including a lower end cover 1 and an upper end cover 5 installed on the lower end cover 1;

[0041] The lower end cover 1 and the upper end cover 5 are fixedly arranged with each other. An annular lamp 51 is further installed on the upper end cover 5. A lamp cover 511 is installed in the middle of the annular lamp 51. The annular lamp 51 in this embodiment is a light-emitting component, and the lamp cover 511 is not light-transmissive;

[0042] A treatment surface 11 is further arranged on the lower end cover 1;

[0043] A first cooling part for circulating and conveying a coolant is further arranged inside the lower end cover 1. The first cooling part is disposed between the lower end cover 1 and the upper end cover 5;

[0046] The treatment surface 11 and the first annular convex part 12 are integrally connected or detachably connected;

[0047] The first annular convex part 12 and the sealing cover 4 are fixedly arranged with each other, and the sealing cover 4 is arranged above the first annular convex part 12;

[0048] A sealing ring 1321 is arranged between the first annular convex part 12 and the sealing cover 4, and the sealing ring 1321 is embedded in the sealing cover 4 or the first annular convex part 12; in this embodiment, a second groove 132 is arranged on the upper end surface of the first annular convex part 12, and the sealing ring 1321 is embedded in the second groove 132; the second groove 132 in this embodiment is not limited to being arranged on the first annular convex part 12, and the second groove 132 can also be arranged on the lower end surface of the sealing cover 4;

[0049] The sealing cover 4, the treatment surface 11 and the first annular convex part 12 enclose a cavity 14, and the disk 2, the circuit board 7 and the second cooling part are all placed inside the cavity 14;

[0050] A liquid discharge interface 41 for discharging the coolant is arranged on the sealing cover 4, and the liquid discharge interface 41 and the sealing cover 4 are integrally connected;

[0051] An injection interface 121 is also arranged on the first annular convex part 12. One end of the injection interface 121 is equipped with an infusion tube 1211 arranged inside the cavity 14. The other end of the infusion tube 1211 is installed on the second cooling part, and the second cooling part for injecting the coolant has a cooling function;

[0052] The second cooling part is used to assist in fixing the disk 2 and convey the coolant inside it to the outside of the second cooling part; in this embodiment, the coolant discharged from the second cooling part acts on the disk 2 and cools it;

[0053] The second cooling part includes a base 61 arranged on the treatment surface 11;

[0054] The base 61 is of a stepped structure, and a second through-hole 602 is provided in the axial direction. The second through-hole 602 is one of a straight through-hole, a tapered through-hole, and a trapezoidal through-hole;

[0055] The lower end of the base 61 is placed in the middle of the disk 2, and the axial side of the base 61 abuts against the disk 2;

[0056] The base 61 and the treatment surface 11 are integrally connected or detachably connected. When the base 61 and the lower end cover 1 are detachably connected, there are two connection methods. One is that a first through-hole 611 is provided on the base 61, and the base 61 is fixed to the lower end cover 1 by assembling screws through the first through-hole 611; the other is that the base 61 and the lower end cover 1 can also be fixed by means of threaded assembly, and the base 61 and the lower end cover 1 are detachably connected through threaded assembly;

[0057] The base 61 and the treatment surface 11 enclose a cooling cavity sealed at the bottom. The volume of the cooling cavity is the same as the volume of the second through-hole 602 provided on the base 61;

[0058] A circuit board 7 is further provided inside the cooling cavity, and the circuit board 7 is mounted on the treatment surface 11;

[0059] A wiring channel 691 and a liquid injection channel 692 are further provided on the axial side of the base 61. A wire for blocking the wiring channel 691 is installed inside the wiring channel 691;

[0060] The base 61 is installed with an infusion tube 1211 through the liquid injection channel 692. The infusion tube 1211 is used to transport a coolant, and the coolant is one of heat-conducting oil, deionized distilled water, C8F16O fluorinated liquid, and fluorocarbon for coolant;

[0061] The coolant injected into the cooling cavity is discharged from the upper end of the base 61.

[0062] In this embodiment, the infusion tube 1211 injects the coolant into the interior of the cooling chamber. The coolant takes away the heat of the circuit board 7 disposed at the bottom end of the cooling chamber and discharges the coolant from the upper end of the cooling chamber, that is, the coolant is discharged from the upper end of the base 61. The discharged coolant enters the cavity 14 outside the base 61. First, the coolant covers the treatment surface 11 below the disk 2 and absorbs the heat between the disk 2 and the treatment surface 11. As the coolant continues to be discharged into the cavity 14 outside the base 61, the coolant covers the disk 2 until the liquid level height of the coolant inside the cavity 14 reaches the liquid discharge interface 41, or even higher than the liquid discharge interface 41, and the coolant is discharged from the liquid discharge interface 41. When the coolant is discharged from the liquid discharge interface 41, the coolant continuously injected into the cooling chamber is continuously discharged from the upper end of the base 61. The opening at the upper end of the base 61 is larger than the size of the liquid injection channel 692, so that the coolant discharged from the upper end of the base 61 flows from the middle of the disk 2 to the outside of the disk 2, driving the coolant inside the cavity 14 to flow towards the liquid discharge interface 41 and be discharged from the liquid discharge interface 41, forming a cooling cycle.

[0063] The cooling method in this embodiment is to first perform liquid cooling and heat dissipation on the circuit board 7 placed inside the second cooling part, and then apply the coolant discharged from the second cooling part to the disk 2 and the treatment surface 11 to prevent the heat generated by the disk 2 from being directly transferred to the circuit board 7. By providing the base 61, the circuit board 7 and the disk 2 are separated, and the coolant sequentially dissipates heat from the circuit board 7 and the disk 2, and performs heat dissipation treatment from the middle of the disk 2 to the outside, improving the utilization rate of the coolant.

[0064] Another embodiment is also involved in this embodiment. The difference between this embodiment and the above embodiment is that a hinge post 612 is further provided on the base 61, and the hinge post 612 and the base 61 are integrally connected or detachably connected;

[0065] A hinge arm 8 is installed on the hinge post 612, and the number of the hinge arms 8 is at least 2;

[0066] One end of the hinge arm 8 is provided with a hinge portion 82, and the hinge portion 82 and the hinge arm 8 are integrally connected. The hinge portion 82 and the hinge post 612 are hinged to each other, and the hinge post 612 passes through the hinge portion 82 and is hinged to the pressure ring 62;

[0067] The middle part of the pressure ring 62 matches the size of the upper end of the base 61, and the pressure ring 62 and the base 61 are coaxially arranged;

[0068] A second spring 68 abuts against the lower end surface of the pressure ring 62, and the lower end of the second spring 68 abuts against the base 61;

[0069] A third through hole 622 is further provided on the pressing ring 62, and the hinged column 612 is arranged in the third through hole 622;

[0070] An annular damping pad 621 is further installed on the lower end surface of the pressing ring 62. The annular damping pad 621 is embedded in the pressing ring 62, and the annular damping pad 621 and the third through hole 622 are coaxially arranged;

[0071] The annular damping pad 621 is arranged between the pressing ring 62 and the hinged part 82;

[0072] The other end of the hinged arm 8 is provided with an embedding part 81 for assisting in fixing the disk 2. The embedding part 81 and the hinged arm 8 are integrally connected;

[0073] The lower end of the embedding part 81 is embedded in the lower end cover 1. The lower end cover 1 is provided with a first groove 131 corresponding to the embedding part 81. The size of the first groove 131 matches the size of the lower end of the embedding part 81. In this embodiment, the damping sleeve 3 is installed on the embedding part 81;

[0074] A first fastener 63 is further installed on the base 61. The first fastener 63 and the base 61 are detachably connected. The first fastener 63 is a nut or a top ring; when the first fastener 63 is a top ring, the lower end surface of the sealing cover 4 abuts against the top ring by fixing the sealing cover 4 and the first annular protrusion 12 to each other, and drives the top ring to act on the pressing ring 62; when the first fastener 63 is a nut, the pressing ring 62 squeezes the second spring 68 through the threaded cooperation between the nut and the base 61; the upper end of the first fastener 63 abuts against the sealing cover 4 or the first fastener 63 does not contact the sealing cover 4; when the first fastener 63 abuts against the sealing cover 4, the stability of the pressing ring 62 is further improved.

[0075] In this embodiment, by arranging the hinged arm 8 on the base 61 to assist in fixing the disk, the hinged arm 8 has the characteristics of being convenient for batch assembly. By installing the pressing ring 62 on the base 61, the hinged arm 8 can be batch installed on the base 61. By arranging the annular damping pad 621 between the hinged part 82 of the hinged arm 8 and the pressing ring 62, the assembled hinged arm 8 has high stability and will not rotate randomly under the limitation of the hinge shaft.
