Description

Technical Field

[0001] This utility model relates to the field of magnetic therapy equipment technology, and in particular to a magnetic circuit structure with oblique magnetization and a rotating magnetic component composed therefrom. Background Technology

[0002] A small magnetic field therapy device is an instrument that uses magnetic fields to perform magnetic therapy based on their influence on the human body. Magnetic fields can alter the physiological and biochemical processes of tissue cells by affecting the distribution of electric currents in the human body, the movement of charged particles, and the permeability of membrane systems. This generates certain biocurrents, changes cell activity, and consequently produces a series of therapeutic effects.

[0003] Existing small-scale magnetic stimulation devices are mainly placed inside mattresses or massage chair backrests, requiring a thin overall shape and a large effective magnetic field space (vertical height and horizontal diameter). Therefore, the magnets in the magnetic components of current small-scale magnetic stimulation devices consist of one or two pieces, and their magnetic circuit structures are mainly of two types, one of which is as follows... Figure 1 As shown, a magnetic circuit structure with vertically upward axial magnetization is composed of a magnet 1 (vertically upward axially magnetized), a base plate 2 for fixing the magnet, and an intermediate positioning sleeve 3; another type is as follows... Figure 2 As shown, this is a single cylindrical (radially magnetized) magnetic circuit structure; Figure 1 and Figure 2 The arrow in the image indicates the direction of magnetization.

[0004] That is, the magnetic components of the existing small magnetic therapy devices generally use vertical or horizontal (radial or axial) magnetization. Due to the small thickness and diameter of the magnet, such magnetic components not only have a low surface magnetic field, but also a small effective spatial magnetic field (vertical height and horizontal diameter). The effective part of the magnetic field lines acting on the human body is very small, making it difficult to achieve the purpose of magnetic field therapy for human diseases. Summary of the Invention

[0005] One of the objectives of this invention is to provide a magnetic circuit structure for oblique magnetization in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A magnetic circuit structure with oblique magnetization includes two main magnetic poles, which are connected in series with the N pole and S pole respectively. The magnetization direction of the N and S poles of the main magnetic poles forms an angle α with the horizontal plane, where 5° < α < 85°.

[0008] As a preferred technical solution, the shape of the main magnetic pole is selected from one of the following: a fan shape, a square shape, a semi-circle shape, or a combination of a circular arc and a rectangle. The fan shape is composed of inner and outer circular arcs and a radial straight edge.

[0009] The second objective of this utility model is to provide a rotary magnetic assembly composed of the above-mentioned obliquely magnetized magnetic circuit structure, which also includes a positioning base plate and an intermediate positioning sleeve. The two main magnetic poles are connected in series with their N-pole and S-pole orientations, and then fixed together by the positioning base plate and the intermediate positioning sleeve. The positioning base plate is located at the bottom of the main magnetic poles, and the intermediate positioning sleeve is located between the two main magnetic poles.

[0010] This invention also provides a better oblique magnetization magnetic circuit structure, which further includes two identical auxiliary magnetic pole groups. Each auxiliary magnetic pole group consists of three auxiliary magnetic poles, namely one auxiliary magnetic pole A and two auxiliary magnetic poles B. The two auxiliary magnetic poles B sandwich one auxiliary magnetic pole A to form a Heilbeck array combination. The magnetization directions of the auxiliary magnetic poles A and B are perpendicular to each other. The two auxiliary magnetic pole groups are close to the side of the main magnetic pole.

[0011] This utility model also provides a vortex magnet assembly composed of the above-mentioned obliquely magnetized magnetic circuit structure. The vortex magnet assembly has two main magnetic poles and two auxiliary magnetic pole groups. It also includes a fixing block and an intermediate positioning sleeve. The two main magnetic poles and the two auxiliary magnetic pole groups are spliced ​​together by the fixing block and the intermediate positioning sleeve to form a complete cylinder.

[0012] Compared with the prior art, the advantages of this utility model are as follows: the magnetic component of this utility model, under the condition of using the same volume of magnetic material as the prior art, has a penetration depth that is more than 1.5 times that of the prior art, and the surface magnetic field is increased from 9000 Gauss to more than 12000 Gauss. When used in a magnetic therapy device, it can significantly improve the effect of magnetic therapy. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Example 1:

[0023] A magnetic circuit structure with oblique magnetization includes two main magnetic poles 1, which are connected in series with their N and S poles facing each other. The magnetization directions of the N and S poles of the main magnetic poles form an angle α with the horizontal plane, where 5° < α < 85°. In this embodiment, the angle α is 45°. Figure 3 The direction of the arrow in the diagram indicates the magnetization direction.

[0024] In this embodiment, the main magnetic pole is fan-shaped (composed of inner and outer arcs and two straight sides).

[0025] The gyromagnetic assembly, composed of the aforementioned obliquely magnetized magnetic circuit structure, is described in [reference needed]. Figure 3 It also includes a positioning base plate 2 and an intermediate positioning sleeve 3. The two main magnetic poles 1 are connected in series with N-S poles and then fixed together by the positioning base plate 2 and the intermediate positioning sleeve 3. The positioning base plate 2 is located at the bottom of the main magnetic pole 1 and the intermediate positioning sleeve 3 is located between the two main magnetic poles 1.

[0026] The aforementioned obliquely magnetized magnetic circuit structure not only achieves a high vertical magnetic field penetration height, but also ensures that the horizontal magnetic field penetration height is almost equal to the vertical penetration height, exceeding 1.5 times that of existing technologies using equivalent magnets. This magnetic circuit structure is particularly suitable for installation in confined spaces such as mattress interiors and massage chair backs. The two main magnetic poles (N~S series connection) are obliquely magnetized. Due to the thinness of the mattress, the rotating magnetic circuit assembly and motor are integrated into one unit. Figure 4 As shown, the overall height needs to be small, and the human body needs to be comfortable sleeping on the mattress, which necessarily requires a thin magnetic circuit and high magnetic field penetration.

[0027] Figure 4 In the process, the gyromagnetic assembly composed of the main magnetic poles 1 is mounted on the motor 5 via the motor spindle 4, and then fixed to the motor 5 with screws 6 and pressure plates 7. The motor 5 drives the gyromagnetic assembly to form a rotating magnetic field. Figure 4 In the middle, the arrow points in the direction of magnetization of the main magnetic pole 1;

[0028] Using the solution of this embodiment, under the condition of using the same volume of magnetic material as the prior art, its penetration depth is more than 1.5 times that of the prior art. The actual measurement shows that when it is 400mm away from the magnet surface, the magnetic field B value reaches 2 Gauss, and the highest magnetic field B on the magnet surface is <10000 Gauss.

[0029] For magnets of the same specifications, the conventional vertical axis magnetization (α=90°) is used. When the magnet is 250mm away from the surface, the magnetic field B value is only 2 Gauss, and the surface magnetic field B < 9000 Gauss.

[0030] Example 2

[0031] Compared with Example 1, this embodiment is as follows: Figure 5 As shown, in addition to the two main magnetic poles 1, there are also two identical auxiliary magnetic pole groups. Each auxiliary magnetic pole group consists of three auxiliary magnetic poles: one auxiliary magnetic pole 8 and two auxiliary magnetic poles 9. The two auxiliary magnetic poles 9 sandwich one auxiliary magnetic pole 8 to form a Heilbeck array. The magnetization directions of the auxiliary magnetic poles 8 and 9 are perpendicular to each other. Figure 5 In the case of β=90°, such as Figure 6 and Figure 7 As shown, Figure 6 and Figure 7 The arrow in the diagram indicates the magnetization direction. The two auxiliary magnetic pole groups are closely attached to the side of the main magnetic pole 1. The diagram also includes a filling fixing block 10 and an intermediate positioning sleeve 3. The two main magnetic poles 1 and the two auxiliary magnetic pole groups are spliced ​​together into a complete cylinder by the filling fixing block 10 and the intermediate positioning sleeve 3.

[0032] The scheme adopted in this embodiment, based on embodiment 1, retains the high penetration characteristics of the oblique magnetization magnetic field (more than 1.5 times that of the same specification; in actual measurement, when 400mm away from the magnet surface, the magnetic field value B reaches 2 Gauss, and the highest magnetic field B on the magnet surface is <10000 Gauss). Most importantly, the surface magnetic intensity of the magnet is increased from B <10000 Gauss to B >>12000 Gauss. The increase in surface magnetic intensity increases the effect of the magnetic field on the human body.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
