The improvement of this patent brings the following advantage:
(1) the utility model discloses a high magnetism physiotherapy device sets up many magnetism needles in hollow magnetic core inside for replace the whole iron core that prior art placed in the magnetic core. After hundreds of times of repeated experiments and combined use experience, the inventor unexpectedly finds that the magnetic needle bundle consisting of a plurality of magnetic needles is used as a component for enhancing the magnetic field of the coil, and the enhancement effect is better than that of using a whole iron core. The magnetic needle bundle composed of the magnetic needles enables the magnetic fields of the magnetic needles to be mutually superposed, so that the magnetic fields are more concentrated and the strength is higher. The magnetic field has stronger penetrating power to the surface of the human body, so that the magnetic field reaches deeper parts of the human body, and the treatment effect is better exerted.
(2) In addition to the fact that the magnetic fields of a plurality of magnetic needles can be superposed to concentrate and increase the magnetic fields, the inventor also conducts a great number of repeated tests on the length, thickness and number of the magnetic needles through a great number of experiments to detect how to select various types of magnetic needles so as to achieve the purpose of enhancing the magnetic fields to the maximum extent under the limiting conditions of limited volume, current, voltage, weight and the like. The experimental result shows that when the length of the magnetic needle is 50-130mm, the diameter is 2-6mm, and the number of the magnetic needles is 30-50, the strength of the magnetic field reaches the maximum. Beyond this range, too much or too little will result in a decay of the magnetic field, unlike the common sense of the skilled person. For example, when the length of the magnetic needle exceeds 130mm, the magnetic field is weaker than that when the magnetic needle in the above range is used; the length is shorter than 50mm, and the magnetic flux can not achieve the magnetic therapy effect. The length of the magnetic needle is 110mm, the diameter is 4mm, the number is 39, and the magnetic field with more than 15000 gauss can be formed.
(3) As an improvement, coils are also important factors affecting the magnetic field strength and the concentration in addition to the magnetic needle. The number of turns and the wire diameter of the coil are the key factors influencing the generation of the ultrahigh magnetic field by the large current flowing through the coil. The number of turns of the winding is large, but the wire diameter is small, the resistance values of two ends of the coil are large, the generated magnetic field is weak, the coil has large heat productivity and is easy to burn out, and the working time is less than 50 hours; if the number of turns of the wire is large, the wire diameter is also large, and the magnetic field intensity generated when the operating current is large is also large, but this also increases the load on the circuit, the volume of the device, and the amount of heat generated. Through hundreds of tests, the inventor finds that the diameter of a winding wire of the coil is 0.5-1.5mm, the number of turns is 800-. The diameter of the winding wire of the coil is 1mm, and the number of turns is 1000 turns.
(4) The utility model discloses a high magnetism physiotherapy device inserts the heat dissipation case through the lower part with the magnetopin, especially among the heat radiation structure, lets the magnetopin lower half very close to with the heat radiation fin of heat radiation structure and carries out the heat exchange, can be quick transmit the heat that coil and magnetic core gived off for heat radiation structure fast, then the blast cooling device in the rethread heat dissipation case, when distributing away the heat, strengthened coil magnetic field intensity and played the effect. The damage of the accumulated heat generated by the coil and the magnetic core for a long time to the device parts is effectively avoided. The magnetic needle conducts the temperature of the whole coil through an external contact heat dissipation structure, so that the working current can be continuously improved to act on the coil, and the ultrahigh magnetic field intensity can be generated. In the prior art, the bottom of a coil containing a whole iron core is tightly attached to a radiating fin instead of inserting the lower half parts of a plurality of magnetic needles into the radiating box, so that the radiating effect is poor by 3 times, and the service life is much shorter.
(5) The application discloses electromagnetic pulse treatment chair passes through pulse control circuit, and drive high magnetism physiotherapy device sends superimposed pulsed magnetic field, and magnetic field intensity is big, and the direction is concentrated, and the magnetic field transform is nimble, is that one kind is sharp superimposed pulsed magnetic field, can pierce through human surface direct human 30CM depths deepest even. The electric energy is converted into pulse superposition high magnetic field to act on the surface of a human body by a reliable electronic circuit and a software control principle, the metabolic function of tissue cells is influenced by changing the membrane potential difference, the blood circulation is improved, the permeability of blood vessels is enhanced, the transformation of substances inside and outside the cell membranes is promoted, the auxiliary effect of relieving swelling and pain is achieved, and the function of treating chronic diseases is realized.
(6) As an improvement, the electromagnetic pulse treatment chair disclosed in the present application is further connected to the control circuit through the wireless communication module, and is connected to the wireless control terminal, so that a user can directly control the working state and working time of the electromagnetic pulse treatment chair through the control of the wireless control terminal.

Detailed Description
The embodiments of the present invention are described below with reference to specific embodiments, and other advantages and effects of the present invention will be easily understood by those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention.
As shown in fig. 1 to 5, an embodiment 1 of the present application provides a pulse high magnetic physiotherapy apparatus 200, including: the heat dissipation box 1 with the heat dissipation function is internally provided with a hollow magnetic core, the side surface of the magnetic core is circumferentially wound with a coil, and the coil is connected with a pulse control circuit; the heat dissipation box 1 is provided with a cooling device 2 which can cool the components in the heat dissipation box 1; the inner bottom of the heat dissipation box 1 is provided with a heat dissipation structure 5, and the heat dissipation structure 5 is composed of a plurality of heat dissipation fins which are arranged in parallel; a hollow magnetic core 3 is arranged in the heat dissipation box 1, a coil 4 is wound on the side surface of the magnetic core 3 in the circumferential direction, and the coil 4 is used for generating a magnetic field; the upper end surface of the magnetic core 3 is connected with the heat dissipation box 1, and the lower end surface is connected with the base of the heat dissipation structure 5; the radiating fins are arranged on the lower end face of the base of the radiating structure 5; the upper parts 61 of 30-50 magnetic needles 6 with the length of 50-130mm and the diameter of 2-6mm penetrate through the hollow part of the magnetic core 3, and the lower parts 62 of the magnetic needles 6 are inserted into the heat dissipation structure 5 (see figure 4 for details); the upper part 61 is mainly used for enhancing the magnetic field intensity and guiding the magnetic field direction, and the lower part 62 mainly exchanges heat with the heat dissipation structure 5 to dissipate heat of the coil 4 and the magnetic core 3.
The high magnetic physiotherapy device 200 of the present embodiment generates a high magnetic field by passing a large current through the coil 4 wound with the coil 4, and achieves a linear pulsed magnetic field of an ultra-high magnetic field intensity by scientifically configuring the magnetic core 3, the wire diameter, the number of turns of the coil, the length and the number of the magnetic needles 6 wound with the coil 4, and the like, thereby generating a greater therapeutic effect on a human body.
The heat dissipation structure 5 is preferably made of an aluminum alloy. The magnetic core 3 is preferably formed by machining pure iron.
As shown in fig. 4-5, the magnetic core 3 may have a hub shape having an i-shaped cross section. The upper end and the lower end of the hub-shaped magnetic core 3 are both provided with two wings extending outwards, and the lower wings are directly connected with the heat dissipation structure 5, so that the functions of exchanging heat with the heat dissipation structure 5 and dredging redundant heat can be achieved; the upper wing is connected with the heat radiation box 1, and the magnetic needle 6 arranged in the hollow part can better play the magnetic therapy function on the chair surface.
The hollow portion of the core 3 is a through hole extending along the axis, and the hole diameter thereof is preferably 32 mm.
The winding of the coil 4 is preferably enameled wire.
If the number of turns and the wire diameter of the coil 4 are unreasonably unscientific, the current passing through the coil 4 is easy to be small, and the magnetic field intensity is low; the magnetic field is weak, linear high magnetism cannot be generated, and the magnetic field is not beneficial to human bodies. The diameter of the winding wire of the coil 4 is 0.5-1.5mm, and the number of turns is 800-. The coil 4 is preferably arranged such that the diameter of the winding wire is 1mm and the number of turns is 1000.
The magnetic needle 6 may be a cylinder, a prism, a cuboid, or other long strip shape, and is not limited to this application.
The upper end of the magnetic needle 6 is convex in a conical shape. The upper end part of the conical bulge can concentrate the magnetic field emitted by the magnetic needle 6, thereby enhancing the strength of the magnetic field; meanwhile, the direction of the magnetic field can be finely adjusted by adjusting the direction of the cone. While the intensity and direction of the magnetic field of the single magnetic needle 6 are enhanced and adjusted, the magnetic fields of the magnetic needles 6 are mutually superposed by reasonably configuring the positions of the magnetic needles 6 in the hollow part of the magnetic core 3, so that the intensity of the magnetic field is further improved, and a better treatment effect is obtained.
The length of the magnetic needle 6 can change the direction of the magnetic field and increase the intensity of the magnetic field (the upper part 61). A linear pulsed magnetic field is generated by a linear pulse through the coil 4. The heat dissipation part (lower part 62) of the exposed magnetic needle 6 plays a role in enhancing the magnetic field intensity of the coil 4, meanwhile, the temperature of the coil 4 is conducted to the magnetic needle 6, the magnetic needle 6 contacts the heat dissipation structure 5 through flowing air to conduct the temperature of the whole coil 4 away, so that the working current can be continuously improved to act on the coil 4, and the ultrahigh magnetic field intensity can be generated. Preferably, the magnetic needles 6 have a length of 110mm, a diameter of 4mm and a number of 39. The experimental result shows that when the length of the magnetic needle 6 is 50-130mm, the diameter is 2-6mm, and the number is 30-50, the intensity of the magnetic field reaches the maximum. Beyond this range, too much or too little will result in a decay of the magnetic field, unlike the common sense of the skilled person. For example, when the length of the magnetic needle 6 exceeds 130mm, the magnetic field is weaker than when the magnetic needle 6 in the above range is used.
In order to better dissipate the heat generated by the coil 4 and the magnetic core 3 during operation, the lower part 62 of the magnetic needle 6 is creatively inserted into the heat dissipation structure 5, and the problem of difficult heat dissipation of the coil 4 and the magnetic core 3 is well solved by using the magnetic needle 6 as a heat conduction medium between the coil 4, the magnetic core 3 and the heat dissipation structure 5.
