[0002] The magnetic stimulation coil in the traditional magnetic therapy instrument only has a single-layer or multi-layer planar structure (as Figure 1 shown). After winding, one lead is on the inner side and the other lead is on the outer side. And during use, it is necessary to input current through the lead on the inner side and output current through the lead on the outer side. Since the lead on the inner side needs to be lapped on the outer side of the coil, a special avoidance space needs to be reserved when making the shell of the stimulation coil, which has a certain impact on the structure and appearance design.

[0003] When the above traditional magnetic stimulation coil is in use, it can only perform magnetic therapy on a local part of the limb at a time. After magnetic therapy on one part, it needs to be moved to another part. The whole magnetic therapy process is very troublesome. To achieve whole-arm magnetic therapy, it takes a lot of time and has low efficiency. Summary of the Invention

[0023] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the following provides a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0024] The following provides a detailed description of the present invention with reference to the accompanying drawings and embodiments.

[0025] The present invention provides an arm magnetic therapy device, asFigure 2-6 As shown, it includes a shell 4, and a cylinder 1 for the arm to be sleeved and passed through is arranged on the upper end of the shell 4. A wire tube is wound on the outer wall of the cylinder 1 along the length direction of the cylinder 1. The wire tube is wound on the outer wall of the cylinder 1 with M turns and N layers to form a spiral magnetic stimulation coil 2; the starting end of the wire tube is bent and extended to form a current input pipeline, and the end of the wire tube is bent and extended to form a current output pipeline; M is greater than or equal to 2, and N is greater than or equal to 1; the magnetic stimulation coil 2 is located between the cylinder 1 and the shell 4.

[0026] Specifically, the housing 4 is composed of an upper housing, a bottom housing, a front baffle and a rear baffle, which are fixed by screws and buckle structures and can be disassembled or assembled with each other. The housing 4 is equipped with modules such as a power adapter and a power main control board commonly used in magnetic therapy apparatuses, and four fans 45 for dissipating heat from the power adapter, the power main control board and other modules are installed on the front end surface of the internal space of the housing 4.

[0027] The arm magnetic therapy device also includes a cylinder 1, which is a cylindrical body with a circular hole. After the arm passes through the circular hole, it receives the magnetic therapy effect of the magnetic stimulation coil 2. The magnetic stimulation coil 2 is formed by winding a wire tube. Specifically, the starting end of the wire tube is bent and extended to form a current input pipeline, and the other end is spirally wound around the cylindrical cylinder 1. The number of turns can reach M turns (M≥2), and the number of winding layers can reach N layers (N≥1). The shape can be wound into a cylindrical, rectangular, polygonal, and other shapes (that is, the cross-section of the magnetic stimulation coil 2 perpendicular to its length is a circle or a regular polygon, and the number of sides of the regular polygon is greater than or equal to 4). The wire tube wound to the end is bent and extended to form a current output pipeline. The current output pipeline and the current input pipeline are located on the same side of the magnetic stimulation coil 2 and are arranged adjacent to each other. When magnetic therapy is needed for the arm, the arm can be inserted into the inner side of the hole to achieve magnetic therapy. The magnetic stimulation coil 2 wound on the outer side of the hole can generate a magnetic field in the shape of a cylinder 1 under the action of current to perform magnetic therapy on the arm. Since the generated magnetic field forms a circle in the shape of a cylinder 1, magnetic therapy can be performed on different parts of the arm in 360 degrees at a time during magnetic therapy of the arm, thereby improving the efficiency of magnetic therapy and shortening the time of magnetic therapy.

[0028] Furthermore, a hand support 41 is hinged on the upper surface of the shell 4; the upper surface of the shell 4 is concave to form a support groove 42 for receiving the hand support 41; the hand support 41 is hinged to the upper surface of the shell 4 so that it can be received in the support groove 42 or used to support the arm.

[0029] like Figure 5As shown, the hand bracket 41 is located at the rear left position on the upper surface of the housing 4. One end of the hand bracket 41 is connected to the upper surface of the housing 4 through a conventional hinge (such as the hinge used for the flip pair connection between the notebook screen and its keyboard) or hinge structure. When the user undergoes magnetic therapy, the hand bracket 41 forms an angle of approximately 150 degrees with the upper surface of the housing 4, serving the function of supporting the hand to improve the user experience. After the magnetic therapy is completed, the hand bracket 41 flips towards the magnetic stimulation coil 2 and closes within the bracket slot 42. At this time, the upper surface of the hand bracket 41 is basically flush with the upper surface of the housing 4, preventing accidental damage to the hand bracket 41 during the transportation of the magnetic therapy device.

[0030] Furthermore, a key panel 43 for selecting magnetic therapy modes or adjusting magnetic therapy parameters is provided on the upper surface of the housing 4.

[0031] As Figure 5-6 shown, the key panel 43 is installed on the right side of the upper surface of the housing 4 and is specifically a touch screen. The screen displays various operating parameters of the magnetic therapy device and virtual keys corresponding to the magnetic therapy mode and magnetic therapy parameter settings.

[0032] Furthermore, the wire tube is formed by stranding and winding 2000 - 3000 copper wire conductors, and the outer surfaces of the copper wire conductors are all coated with insulating layers.

[0033] Furthermore, the wire tube is formed by stranding and winding 2500 copper wire conductors with a diameter of 0.05 - 0.1 mm.

[0034] As Figure 4 shown, in this embodiment, the space between the housing 4 and the cylinder 1 for accommodating the magnetic stimulation coil 2 is annular, with a length of L (about 105 mm), a width of W (about 25 mm), and an inner diameter of D (about 120 mm, which is also the outer wall diameter of the cylinder 1). In order to enable the magnetic stimulation coil 2 to obtain a higher Q value (quality factor) and a lower heating rate in this limited space, the winding method of the magnetic stimulation coil 2 is verified according to the parameters set in Table 1.

[0035] Table 1 Winding parameter table of the magnetic stimulation coil

[0036]

[0037] The heat generation and heat dissipation of the magnetic stimulation coil 2 wound according to the above six schemes are detected at a working frequency of 50 Hz. The specific steps are as follows: At room temperature (25 °C), use an infrared thermal imager or thermocouple to measure the initial surface temperature (T 0 ) of the coil, connect the coil to a constant current source, apply the rated working current (1 A), continuously heat until the coil temperature tends to be stable, and record the time (t 1 ) and temperature (T 1) After the coil temperature stabilizes, disconnect the input current, and then record the time (t 2 ) and temperature (T 2 ) of the natural cooling of the coil temperature. Obtain Table 2 and Figure 7 data.

[0038] Table 2 Temperature Data of the Magnetic Stimulation Coil

[0039]

[0040]

[0041] It can be seen from Table 2 combined with Figure 7 that in the heating stage, in Plan 4, the temperature rises to 80 °C at the 13th minute, with the slowest heating rate and the lowest final temperature; for other plans, the heating time is shorter and the temperature is higher. In the cooling stage, in Plan 4, the temperature drops from 80 °C to 50 °C within 5 minutes, with the fastest cooling rate; for other plans, the cooling amplitude is smaller. Generally speaking, due to its slow heating (reducing thermal stress) and fast cooling (enhancing safety), Plan 4 has the best comprehensive performance.

[0042] Furthermore, as Figure 2-3 shown, a sheath 3 for improving the arm comfort is provided on the inner wall of the cylinder 1. The sheath 3 is inserted into the circular hole of the cylinder 1. The middle part of the sheath 3 is designed with a highly elastic mesh fabric, and the elastic "O" - shaped sealing ring design at both ends can firmly sleeve the ends of the cylinder 1.

[0043] Furthermore, as Figure 2-6 shown, to ensure the stability of magnetic therapy and avoid thermal runaway of the magnetic stimulation coil 2, a 1 - 2 mm gap is provided between the outer circle of the magnetic stimulation coil 2 and the outer shell 4 to form a heat dissipation air path; and a heat dissipation port 41 communicating with the heat dissipation air path is opened at the top of the outer shell 4.

[0044] Furthermore, as Figure 2-6 shown, a support plate 11 is clamped to the bottom of the outer wall of the cylinder 1 through a clamping structure. A heat dissipation fan 12 for dissipating heat from the magnetic stimulation coil 2 is fixedly arranged on the support plate 11 by screws to further ensure the stability of magnetic therapy and avoid thermal runaway of the magnetic stimulation coil 2. The heat dissipation fan 12 is located directly below the cylinder 1. Compared with being located on its left and right sides, it reduces the center of gravity of the cylinder 1, thereby improving the stability of the cylinder 1, and indirectly improving the stability of the arm magnetic stimulation assembly and reducing the vibration effect during magnetic therapy.

[0045] Furthermore, in order to avoid thermal runaway of the magnetic stimulation coil 2, a thermostat (not shown in the drawings) is provided in the heat dissipation air path. The thermostat is attached to the surface of the magnetic stimulation coil 2 and acts as a temperature switch. It is connected in series with the cooling fan 12. When the temperature of the magnetic stimulation coil 2 or in the heat dissipation air path is detected to be higher than the preset temperature, the power supply circuit of the cooling fan 12 is cut off.

[0046] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
