Description

[Technical field]

[0001] The present invention relates to a covered negative magnetic field device, and more particularly to a covered negative magnetic field device that can be attached to a part of the human body and that has a beneficial effect on the human body through a magnetic field. [Background technology]

[0002] Dr. Albert Roy Davis, an American biophysicist, discovered that there are two distinctly different effects that the cosmic magnetic poles have on living organisms. The positive magnetic field effect is positively charged and has effects such as oxidation, acidification, activation, excitement, and pressure increase, while the negative magnetic field effect is negatively charged and has effects such as reduction, alkalinization, relaxation, sedation, and stress resistance.

[0003] According to the Biot-Savart Law, only when the biomagnetic field of a human body part is adapted to the large magnetic field of the universe can the normal physiological state of the human tissues and organs be maintained, otherwise abnormal reactions or illness may occur. When different kinds of wounds occur in the human body part, the electric and magnetic fields of the part are always positive, and through the mechanism of the meridians and nervous system, the negative magnetic field concentrated in the body reaches the affected part and is completely healed. Since there is no help of oxygen in the acidic environment, the repair process is in an alkaline environment, and the effect is good.

[0004] When using magnets to maintain and improve health, magnets are attached to the human body, but because the surface of the human body is not flat, each part has a different curve, and these curves differ from person to person. For this reason, there has been a demand for a negative magnetic field device that can attach magnets to the curves of each individual. Summary of the Invention [Problem to be solved by the invention]

[0022] The covered negative magnetic field device 10 according to the present invention has a structure that can be attached to the human body and has a variety of embodiments. The detailed layout of the structure, which differs depending on the embodiment, will be described below.

[0023] (First embodiment) Please refer to Figures 1 and 2. FIG 1 is a perspective view of a cover type negative magnetic field device according to a first embodiment of the present invention. FIG 2 is a cross-sectional view of a cover type negative magnetic field device according to a first embodiment of the present invention. As shown in FIG 1 and FIG 2, a cover type negative magnetic field device 10 according to the first embodiment includes a cover 20 and a plurality of first magnetic members 30.

[0024] The covering 20 is made of silicone and has an S pole corresponding surface 21 and an N pole corresponding surface 22. The S pole corresponding surface 21 and the N pole corresponding surface 22 are provided on both sides of the covering 20 in a front-back relationship. A plurality of first magnetic members 30 are disposed inside the covering 20. The first magnetic members 30 of the first embodiment are uniformly arranged in the covering 20, and have a vertical interval D1 formed vertically between each two adjacent first magnetic members 30, and a horizontal interval D2 formed horizontally between each two adjacent first magnetic members 30. The vertical interval D1 or the horizontal interval D2 is formed between each two adjacent first magnetic members 30. Therefore, the first magnetic members 30 are spaced apart from each other, preventing the first magnetic members 30 from attracting each other. Each first magnetic member 30 is a permanent magnet. Each first magnetic member 30 has a first S pole surface 31 and a first N pole surface 32.

[0025] In the first embodiment, each first S pole surface 31 is located on the same side as the S pole corresponding surface 21, and in order to prevent each first magnetic member 30 from losing its magnetic attraction effect due to the isolation of the coating 20, there is an S pole effective magnetic attraction gap D3 between each first S pole surface 31 and the S pole corresponding surface 21. The S pole effective magnetic attraction gap D3 does not exceed 10 mm (including 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm). Therefore, the coating 20 can cover each first magnetic member 30 and maintain the magnetic attraction effect of each first magnetic member 30. Each first N-pole surface 32 is located on the same side as the N-pole corresponding surface 22, and in order to prevent each first magnetic member 30 from losing its magnetic attraction effect due to isolation by the coating 20, there is an N-pole effective magnetic attraction gap D4 between each first N-pole surface 32 and the N-pole corresponding surface 22, and the N-pole effective magnetic attraction gap D4 does not exceed 10 mm (including 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm), so that the coating 20 covers each first magnetic member 30 and each first magnetic member 30 can maintain its magnetic attraction effect.

[0026] In actual use, the S pole corresponding surface 21 is attached to the skin of the human body, particularly to the affected area, and the negative magnetic effect of the first magnetic member 30 inside the S pole corresponding surface 21 provides effects such as reduction, alkalinization, relaxation, sedation, and stress resistance to the affected area. In other embodiments, the N pole corresponding surface 22 may be attached to the skin of the human body, and the present invention is not limited to the first embodiment.

[0028] The cover type negative magnetic field device according to the second embodiment of the present invention further includes a vibration device 40, and the cover 20 has an insertion chamber 23, which is different from the first embodiment. The other structures are the same as those of the first embodiment, so they will not be described in detail here. The above-mentioned insertion chamber 23 does not penetrate the cover 20. In other words, the insertion chamber 23 has only one opening on the cover 20. The vibration device 40 includes a vibration motor 41 and a power source 42. The vibration motor 41 is not limited to these, but may be, for example, an electric motor, a pneumatic motor, or a hydraulic motor. The vibration motor 41 is electrically connected to the power source 42. The above-mentioned power source 42 is an external power source or a built-in power source. The built-in power source is electrically connected to a circuit board. The above-mentioned circuit board controls the power supply mechanism of the built-in power source and adjusts the power supply time or power supply current, thereby adjusting the vibration time or vibration intensity of the vibration motor 41. Therefore, when actually using it, the vibration motor 41 is inserted into the insertion tank 23, and the S pole corresponding surface 21 is attached to the skin of the human body, especially the affected area, and the negative magnetic effect is used to obtain effects such as reduction, alkalinization, relaxation, sedation, and stress resistance of the affected area. When the vibration motor 41 is driven, each first magnetic member 30 is vibrated, enhancing the magnetic field effect, and by striking each first magnetic member 30, the magnetic field can be strengthened and can reach deep from the skin to the muscles.

As shown in FIG 5 and FIG 6, the cover type negative magnetic field device 10 according to the third embodiment of the present invention includes a cover 20, a plurality of first magnetic members 30, and a vibration device 40.

[0030] The cover type negative magnetic field device according to the third embodiment of the present invention further includes a vibration device 40, and the cover 20 has an insertion hole 24. The other structures are the same as those of the first embodiment, so they will not be described in detail here. The above-mentioned insertion hole 24 is formed by penetrating the cover 20. In other words, the insertion hole 24 has at least two openings on the cover 20. The vibration device 40 includes a vibration motor 41 and a power source 42. The vibration motor 41 is not limited to these, but may be, for example, an electric motor, a pneumatic motor, or a hydraulic motor. The vibration motor 41 is electrically connected to the power source 42. The above-mentioned power source 42 is an external power source or a built-in power source. The built-in power source is electrically connected to a circuit board. The above-mentioned circuit board controls the power supply mechanism of the built-in power source and adjusts the power supply time or power supply current, thereby adjusting the vibration time or vibration intensity of the vibration motor 41. Therefore, when actually using it, the vibration motor 41 is inserted into the insertion hole 24, and the S pole corresponding surface 21 is attached to the skin of the human body, especially the affected area, and the negative magnetic effect is used to obtain effects such as reduction, alkalinization, relaxation, sedation, and stress resistance of the affected area. When the vibration motor 41 is driven, each first magnetic member 30 is vibrated, strengthening the magnetic field effect, and by tapping each first magnetic member 30, the magnetic field is strengthened and reaches deep from the skin to the muscle.

[0031] Please refer to Figure 7. FIG. 7 is a perspective view showing another embodiment of the cover type negative magnetic field device according to the third embodiment of the present invention.

[0033] The cover-type negative magnetic field device 10 of the fourth embodiment of the present invention differs from the first embodiment only in that it further comprises a vibration device 40, an additional covering body 50 and a second magnetic member 60. The covering body 20 and the multiple first magnetic members 30 of the fourth embodiment are the same as those of the first embodiment, but will not be described in detail here.

[0034] The vibration device 40 includes a vibration motor 41 and a power source 42. The vibration motor 41 may be, for example, an electric motor, a pneumatic motor, or a hydraulic motor, but is not limited to these. The vibration motor 41 is electrically connected to the power source 42. The above-mentioned power source 42 is an external power source or a built-in power source.

The second magnetic member 60 is a permanent magnet. The second magnetic member 60 has a second south pole surface 61 and a second north pole surface 62.

[0036] In the fourth embodiment, each second S pole surface 61 is located on the same side as the S pole corresponding surface 51.
