Description

TECHNICAL FIELD

[0001] The utility model relates to cosmetic instrument technical field, especially point to a kind of high magnetic flux density magnetic force slim handle. BACKGROUND

[0002] Magnetic force slim uses HI-EMT (high-energy focused electromagnetic wave) technology to make autologous muscle contract and relax continuously, carry out extreme training, so that muscle internal structure can be deeply remodeled, i.e. muscle fiber growth (muscle enlargement) and new protein chain and muscle fiber (muscle hyperplasia) are generated, so as to train and increase muscle density and volume. The extreme muscle contraction of HI-EMT technology can trigger a large amount of fat decomposition, and fatty acids are decomposed and flow out from triglycerides, and accumulate in a large amount in fat cells. When the concentration of fatty acids is too high, the fat cells undergo apoptosis, and are metabolized and excreted from the body within a few weeks. Therefore, magnetic force slim can strengthen and increase muscle while achieving the effect of fat reduction.

When the electromagnetic slimming therapeutic instrument is used, one side of the coil is close to the user. For example, the utility model patent with the announcement number CN219981380U discloses a magnetic force slim handle air cooling structure. When used, one side of the main component coil 5 is close to the user, while the magnetic field of the other side cannot be utilized. At the same time, due to the large air magnetic resistance, the magnetic loss is large, so the utilization rate is low. UTILITY MODEL CONTENT

DRAWINGS

[0021] In order to more clearly illustrate the technical scheme in the embodiments of the utility model or the prior art, the following will briefly introduce the drawings needed to be used in the embodiment or the prior art description, and obviously, the drawings in the following description are only some embodiments of the utility model, and for those skilled in the art, other drawings can also be obtained according to these drawings without paying the creative labor.

[0022] Figure 1 It is a structure schematic view of the utility model discloses a high magnetic flux density magnetic force slim handle. CONCRETE IMPLEMENTING METHOD

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] As Figure 1 shown in the utility model discloses a high magnetic flux density magnetic force slim handle, comprising:

[0025] The coil 1 for generating a magnetic field around the inner diameter and the outer diameter when current passes through;

[0026] The magnetic core 2 for improving the magnetic flux density, the magnetic core 2 is arranged in the coil 1;

[0027] The magnetic plate 3 for improving the magnetic flux density, the magnetic plate 3 is arranged on one side of the coil 1, and the magnetic plate 3 is connected with the magnetic core 2.

[0028] The utility model discloses a high magnetic flux density magnetic force slim handle based on the following principles:

[0029] 1, the magnetic field intensity change generated by the current in the air:

[0030] 1.1, the magnetic field intensity in the air will decrease with the increase of the distance from the current source. This is because the magnetic field presents a ring shape, with the increase of the distance, the density of the magnetic field line decreases, so that the magnetic field intensity decreases.

[0031] 1.2, the magnetic field intensity generated by the current in the air is also related to the current intensity and the conductor shape:

[0032] According to Maxwell loop theorem, the magnetic field intensity is proportional to the current intensity, and is related to the conductor shape.

[0033] 2, the magnetic field intensity change generated by the current in the magnetic core:

[0034] 2.1, the magnetic field intensity in the magnetic core is much higher than that in the air. This is because the magnetic core has good magnetic conductivity, which can enhance the magnetic field.

[0035] 2.2, the magnetic field intensity change generated by the current in the magnetic core depends on the material and shape of the magnetic core. Different magnetic core materials have different magnetic conductivity, and the shape of the magnetic core also affects the distribution of the magnetic field.

[0036] When the current passes through the coil 1, the magnetic field is generated around the inner and outer diameters of the coil 1, and the magnetic field strength is weaker when the outer diameter of the coil 1 is farther away from the outside, and the existing magnetic force slim handle is close to the user when in use, and the magnetic field of the back surface is far away from the user and cannot be utilized, so the utilization rate is low. The utility model discloses a kind of high magnetic flux density magnetic force slim handle, magnetic core 2 is added on coil 1, because the magnetic resistance of magnetic core 2 is greatly reduced than air, so its magnetic loss is greatly reduced, coil 1 center hole is sleeved on the center column of magnetic core 2, and most of the magnetic field of coil 1 back surface is transmitted through magnetic plate 3 and the center column of magnetic core 2 due to different magnetic resistances during work, which greatly reduces magnetic loss, so that the center column magnetic field strength is greatly increased, and the magnetic force slim handle is close to patient when in use, and the magnetic flux density and magnetic field strength are greatly increased, the experience effect is greatly increased, and the treatment effect is obviously improved.

[0037] Wherein, the magnetic core 2 is any one of circular magnetic core, annular magnetic core, oval magnetic core, oval annular magnetic core, C-shaped magnetic core, L-shaped magnetic core, star-shaped magnetic core, triangular magnetic core, quadrilateral magnetic core or polygonal magnetic core. Because the magnetic core 2 has good magnetic conductivity and processability, it can be processed into different forms, so different shapes can be processed according to actual application and different treatment positions to meet different needs, and the application range is greatly expanded.

[0038] Wherein, the magnetic plate 3 is any one of circular magnetic plate, oval magnetic plate, sector magnetic plate, C-shaped magnetic plate, L-shaped magnetic plate, triangular magnetic plate, quadrilateral magnetic plate or polygonal magnetic plate. Because the magnetic plate 3 has good magnetic conductivity and processability, it can be processed into different forms, so different shapes can be processed according to actual application and different treatment positions to meet different needs, and the application range is greatly expanded.

[0039] Wherein, the magnetic core 2 is any one of silicon steel magnetic core, ferrite magnetic core, permalloy magnetic core or nanocrystalline alloy magnetic core, to have better enhanced magnetic field conduction efficiency effect.

[0040] Wherein, the magnetic plate 3 is any one of silicon steel magnetic plate, ferrite magnetic plate, permalloy magnetic plate or nanocrystalline alloy magnetic plate, to have better enhanced magnetic field conduction efficiency effect.

[0041] Wherein, the relative permeability μr of the magnetic core 2 and the magnetic plate 3 is greater than or equal to 100, to enhance the magnetic field conduction efficiency.

[0042] Wherein, the magnetic core 2 and the magnetic plate 3 are combined to form a closed or semi-closed magnetic circuit, and the air gap length in the magnetic circuit is less than or equal to 0.5 mm, to reduce the magnetic resistance and improve the magnetic flux utilization rate.

[0043] The magnetic core 2 is threadedly connected, buckled, magnetically attracted or integrally formed with the magnetic plate 3. When the magnetic core 2 is threadedly connected, buckled or magnetically attracted with the magnetic plate 3, the maintenance, replacement or combination debugging of the magnetic core 2 and the magnetic plate 3 are facilitated.

[0044] The thickness of the magnetic plate 3 is d: 1mm≤d≤10mm.

[0045] According to experiments, when the thickness d of the magnetic plate 3 is 1mm-10mm, the magnetic plate is in a linear magnetic conduction region, the magnetic permeability is stable, the magnetic flux density is approximately linearly related to the thickness, and the magnetic field strength can be effectively improved; when d<1mm, the magnetic resistance is large and the magnetic enhancement effect is poor; when d>10mm, it is easy to saturate and the marginal benefit decreases.

[0046] At the same time, too thin magnetic plates, for example d<1mm, are prone to deformation or fracture due to mechanical stress, such as extrusion during installation and use, especially for hard and brittle ferrite materials, the processing and assembly difficulty increases significantly, the process is complex, and the yield is low; too thick magnetic plates, for example d>10mm, have too large weight, resulting in reduced portability of the handle, and may affect the consistency of magnetic properties due to internal material defects such as bubbles, impurities, etc., resulting in material waste and cost explosion. When the thickness d of the magnetic plate 3 is 1mm-10mm, the mainstream magnetic plate manufacturing processes, such as stamping, sintering and cutting, are easy to realize precise processing, can ensure the surface flatness and dimensional accuracy, for example, the tolerance is controlled within ±0.1mm, meeting the precision requirements of magnetic circuit design; ultra-thin or ultra-thick magnetic plates require special processes, have high cost and low yield, and are not suitable for mass production.

[0047] Finally, the magnetic force slim handle needs to be operated close to the human skin, and the thickness of the magnetic plate directly affects the grip feeling and the ability to fit the curved surface of the handle. Too thin magnetic plates, for example d<1mm, may result in insufficient internal structural strength of the handle or local overheating due to uneven magnetic flux density; too thick magnetic plates, for example d>10mm, will increase the overall thickness of the handle, making it difficult to closely fit the concave and convex parts of the abdomen, thighs and other parts, affecting the magnetic field effect, and generating Joule heat during electromagnetic conversion. The thickness of the magnetic plate affects the heat dissipation path: when the thickness d of the magnetic plate 3 is 1mm-10mm, the magnetic plate can act as a heat dissipation medium to conduct heat away from the coil, preventing local temperature from exceeding 45℃, which may cause user discomfort; both too thin and too thick magnetic plates may hinder heat dissipation, triggering device overheating protection or reducing service life.

[0048] Therefore, by limiting the thickness d of the magnetic plate to 1mm-10mm, both the magnetic flux density can be effectively improved by high magnetic permeability materials, and the manufacturing feasibility, ergonomics and device reliability are also considered, which is the optimal solution combining theoretical analysis and engineering practice.

[0049] The surface of the magnetic plate 3 away from the magnetic core 2 is a curved surface to adapt to the curved surface of the human body and uniformly distribute the magnetic field.

[0050] Wherein, the surface area of the magnetic plate 3 is S, the surface area of the coil 1 close to the side of the user is S0, S≥S0, to cover the effective magnetic field area of the coil 1 and guide the magnetic force lines to concentrate on the target part of the human body.

[0051] Wherein, the coil 1 is a multi-layer tightly wound coil, the number of turns of the coil 1 N≥100 turns, and the wire of the coil 1 is enameled copper wire or litz wire, to enhance the magnetic field strength and reduce the eddy current loss.

[0052] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
