Specifically, as shown in fig. 3, when the magnetic force generated by the magnet 11 is emitted to the surroundings, the magnetic force is blocked and reflected by the shielding case 12, and the propagation direction of the magnetic force is changed so that the magnetic force can only be transmitted from the unshielded side, thereby increasing the magnetic field intensity at the unshielded side and further increasing the emission height of the magnetic force lines.
In the embodiment provided by the present invention, the structural shapes of the magnet 11 and the open cavity 121 are various, wherein preferably, in order to facilitate the production and assembly of the directional magnetic concentrating module and provide the magnetic concentrating effect, in a specific implementation manner of the present embodiment, the open cavity is a cylindrical cavity, and the external structure of the magnet is a cylindrical shape.
In addition, as shown in fig. 4, in a specific embodiment of this embodiment, a screw 131 is used as the fixing member, and it can be understood that, in this case, in order to fix the magnet 11, corresponding hole positions are provided at corresponding positions of the shielding shell 12 and the magnet 11.
As shown in fig. 5, in another embodiment of this embodiment, the fixing member is a fixing layer 132 having an external structure adapted to the open cavity and having a cavity adapted to the external structure of the magnet, wherein one end of the cavity is closed and the other end is not closed, the fixing layer 132 is installed in the open cavity 121 during assembly, the magnet 11 is installed in the cavity of the fixing layer 132, and the opening of the cavity of the fixing layer 132 is on the same side as the opening of the open cavity 132 after assembly.

Further, in the research and development test process, it is found that, under the same condition, the emission height of the magnetic force line of the directional magnetism gathering module 1 can be influenced by adjusting the distance between the magnet 11 and the shielding shell 12, and in order to make the emission height of the magnetic force line larger, after a large number of experiments and data analysis, the embodiment provides a preferred scheme capable of further improving the magnetic emission height of the directional magnetism gathering module: namely, the distance between the side wall of the open cavity 121 and the side wall of the magnet 11 is a/(H D), where H is B/μ 0-M, where a is a coefficient ranging from 0.07 to 0.09, H represents the magnetic field strength, B represents the magnetic induction, μ 0 represents the magnetic permeability in vacuum, M represents the magnetization, H represents the thickness of the cylindrical magnet, and D represents the diameter of the cylindrical magnet.
As shown in fig. 7, the present invention provides a magnetic focusing apparatus, wherein the magnetic focusing apparatus comprises:
4 directional magnetic gathering modules 1, wherein the directional magnetic gathering modules 1 are the same as those in the above embodiments, and for avoiding redundancy, the embodiment will not be described repeatedly herein; in addition, the magnetic gathering device further comprises: the connecting device 2 is provided with 4 mounting positions (not shown) capable of mounting 4 directional magnetism gathering modules respectively, and the 4 directional magnetism gathering modules 1 are arranged on the 4 mounting positions respectively with the same polarity.
Fig. 8 is a schematic diagram of an implementation principle of the magnetic gathering device provided in this embodiment to improve the magnetic gathering effect: because single directional magnetism gathering module 1 can realize unidirectional magnetism gathering, the magnetic line of force of its transmission has a lot of upwards (when the height of magnet 11 upper surface is not higher than the opening of opening chamber 121, the magnetic line of force direction of unidirectional magnetism gathering module all upwards), when two or more directional magnetism gathering modules set up together, can be because of homopolar repulsion's reason, make these transmission direction vertical direction of magnetic line of force of upward (but not vertical direction) transmission draw close (for example in the figure with the transmission direction and the vertical direction have the magnetic line of force of certain contained angle change to spread towards vertical direction), thereby further improve magnetic line of force transmission height. Therefore, the magnetic field influencing area and distance of the 4 directional magnetic gathering modules 1 can be increased through the magnetic gathering device provided by the embodiment, and the magnetic line transmitting distance can be further increased (the transmitting distance of the magnetic line can be increased by more than 2 times through the experiment) under the condition that the volume and the area of the magnet are not increased and the material density is not increased, so that the magnetic therapy product using the magnetic gathering device can achieve the magnetic therapy effect of using low-cost small magnets to achieve high-cost large magnets.
It is understood that in other embodiments provided by the present invention, the magnetic gathering device has other numbers of directional magnetic gathering modules (the number is greater than or equal to 2), and the directional magnetic gathering modules are arranged on the connecting device with the same number of mounting positions in the same pole.
