Description

A magnetocaloric vibrator for a magnetothermal physiotherapy instrument

technical field

The invention relates to the technical field of physiotherapy equipment, in particular to a magnetocaloric vibrator used in a magnetothermal physiotherapy instrument.

Background technique

With the aging trend of my country's population and the acceleration of people's life rhythm, diseases such as bone and joint diseases and soft tissue injuries directly affect the quality of life of middle-aged and elderly people. Magnetothermal physiotherapy instruments are becoming more and more popular, and magnetocaloric vibrators will also be better developed.

The magnetocaloric vibrator of the magnetothermal physiotherapy products currently on the market generally adopts the magnetocaloric vibrator unit used in the market, which consists of eight iron core coils and ten permanent magnets. The magnets are arranged at intervals from the iron core and adjacent The polarity between the two magnets is reversed. When there is no electricity, due to the principle of same-sex repulsion and opposite-sex attraction, adjacent magnets with opposite polarities attract each other, causing the floating magnet in the middle to bounce up; and after the coil is loaded with alternating current, on the one hand, the coil generates an alternating magnetic field, which is connected with the coil. The constant magnetic field of the magnet interacts, and the direction of the magnetic field changes continuously, causing the suspended magnet to produce unique non-mechanical vibrations. On the other hand, the iron core in the coil generates heat due to eddy currents, which produces the magnetic field and vibration required for instrument treatment. , heat three physical therapy factors.

However, the above-mentioned magnetocaloric vibrator provides a single magnetic field, complex material shape, inconvenient assembly, high cost, and the levitating magnet in the magnetocaloric vibrator is easily damaged when vibrating; secondly, the iron core used is slow in warming up, which will lead to the need for thermal treatment The actual treatment time of patients is shortened, which affects the treatment effect.

Contents of the invention

The object of the present invention is to provide a magnetocaloric vibrator with a simple structure for a magnetothermal physiotherapy apparatus in order to overcome the above-mentioned defects in the prior art.

The purpose of the present invention can be achieved through the following technical solutions: a magnetocaloric vibrator for a magnetic vibration thermal physiotherapy instrument, the magnetocaloric vibrator includes an upper shell, a lower shell, and a plurality of parallel coils arranged between the upper shell and the lower shell. A plurality of core-containing coils, two fixed magnets and a plurality of vibrating magnets are provided, the two fixed magnets are arranged horizontally on both sides, and each of the vibrating magnets is arranged between the two core-containing coils. When the core-containing coil is fed with alternating current, an alternating magnetic field is generated, which is affected by the magnetic field of the adjacent magnet to generate magnetic extrusion and vibrates continuously. The resonant magnet is affected by the coil vibration and resonates. Since the core-containing coil is in the alternating magnetic field, the alternating The variable magnetic flux causes an induced current to be generated in the core-containing coil, forming an eddy current effect to generate heat, so the magnetocaloric vibrator device can generate three physical factors of magnetism, vibration and heat at the same time.

The core-containing coil includes a silicon steel rod in the center and an enameled wire wound on the circumference of the silicon steel rod. The silicon steel rod is cylindrical and has no enameled wire wound at both ends. The silicon steel rod not wound with enameled wire has an L-shaped gap, and the L The two sides of the shaped notch are respectively parallel or perpendicular to the axial direction of the silicon steel rod. In the alternating magnetic field, the alternating magnetic flux causes an induced current in the silicon steel rod, forming an eddy current effect and generating heat.

The enameled wire is a high-temperature-resistant copper wire. Since heat is generated in the silicon steel rod, the copper wire in the middle of the enameled wire and the outer coating all need to have the function of high-temperature resistance.

The lower shell and the upper shell are relatively provided with a plurality of coil slots for placing coils containing cores, the length of the coil slots in the lower shell is slightly greater than the total length of the silicon steel rod, and the width of the coil slots in the lower shell is slightly greater than the The maximum diameter of the core coil, the position of the coil slot in the upper case corresponds to the part where the enameled wire is wound in the silicon steel rod, and the length is slightly longer than the length of the part where the enameled wire is wound in the silicon steel rod, and the width of the coil slot in the upper case is slightly larger than the coil containing the core of the maximum diameter. This setting cooperates with the core-containing coil with an L-shaped notch. When installing, the L-shaped notch is facing the upper shell, so that the core-containing coil can vibrate up and down, and the length and width of the coil slot are slightly smaller than the corresponding part of the core-containing coil. Large, generally less than 1mm, to prevent the cored coil from being stuck in the coil groove, so that the up and down vibration will not be affected.

The number of core-containing coils is 3 to 6. If the number of core-containing coils is set within this range, sufficient heat and vibration can be generated on the one hand, and on the other hand, too many core-containing coils will not be connected in parallel at the same time. And cause a larger load on the circuit, resulting in unnecessary accidents.

The vibrating magnet is a strip magnet, and the upper shell and the lower shell are provided with a resonant groove for placing the vibrating magnet, and the length and width of the resonant groove are slightly larger than the length and width of the vibrating magnet. It is also to provide space for the resonance of the vibrating magnet, and the general gap is less than 1mm.

The two fixed magnets are elongated magnets, which are respectively placed on the two sides of the upper shell and the lower shell. The upper shell and the lower shell are provided with fixing grooves for placing the fixed magnets. The length and width are the same as that of the fixed magnet, and the fixed magnet is clamped in the fixed groove.

The magnetic field strength of the fixed magnet is greater than or equal to the magnetic field strength of the vibrating magnet.

Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects:

(1) The magnetocaloric vibrator device can generate three physical factors of magnetism, vibration and heat at the same time, and the therapeutic effect is comprehensive;

(2) The structure is simple, easy to assemble, cleverly avoided the problem that the magnet is not easy to be finished, uses a simple magnet structure, and provides different therapeutic magnetic fields required by clinical practice to maximize the curative effect;

(3) By selecting different voltages, different temperature working environments and vibration environments can be obtained, and magnets with different surface magnetism can be selected to meet the clinical needs of patients for different treatment magnetic fields, and the size of the magnet coil can be changed to better respond to the needs of different treatment parts. It can provide patients with more choices for the magnetic vibration thermal physiotherapy instrument to maximize the curative effect.
