Description

Technical Field

[0001] This utility model relates to the field of physiotherapy equipment technology, specifically to the main structure of a magnetic therapy massager. Background Technology

[0002] The method of using magnetic fields to treat diseases is called magnetic field therapy, or simply magnetotherapy. When a magnetic field acts on the human body, it can change the magnitude and direction of the body's bioelectric currents, generating weak eddy currents. This affects the direction of electron movement within the body, the distribution, concentration, and speed of movement of ions inside and outside cells, alters cell membrane potential, affects nerve excitability, and changes cell membrane permeability, intracellular and extracellular material exchange, and biochemical processes.

[0003] The existing magnetic therapy massager structure includes a main body and a control board housed within it. The main body comprises an upper shell and a lower shell. A motor is fixed inside the upper shell, with its output shaft extending out and connecting to the rotating head. The rotating head consists of an outer end cover, a protective end cover, and an inner end cover. The protective end cover snaps into the inner end cover, and the outer end cover is fixed outside the protective end cover. A rotating disk is housed within the cavity formed by the protective end cover and the inner end cover and is fixedly connected to the inner end cover. Several permanent magnets (e.g., 0.8mm × 0.5mm) (e.g., neodymium iron boron) are embedded in the rotating disk, using a polarity configuration (N poles opposite each other). Most are exposed magnets with a surface magnetic field strength of approximately 400mT. The motor drives the rotating disk to rotate. Above the control board is a switch potentiometer, above which is a knob and a knob cover. A charging plate is located at the bottom of the main body, below which is a charging port. A protective shell for the tail plug is located at the bottom of the main body.

[0004] Existing magnetic therapy massage devices have the following shortcomings: 1. Poor shock absorption and stability: Some models use vibration-damping double-sided tape and slow-rebound sponge to reduce operating noise and vibration; 2. Uneven magnetic field coverage: If the magnetic blocks are not distributed precisely enough, the magnetic field strength may be unstable, affecting the treatment effect; 3. Limited massage function: It usually only relies on the magnetic field generated by rotating magnets for treatment, lacking other massage methods such as tapping and kneading, making it difficult to meet the diverse massage needs of users and limiting the degree of muscle relaxation; 4. Limited applicability: Some portable magnetic massagers are not convenient to adjust the angle or position of the massage head according to individual differences such as the size of the user's limbs and the massage area, making it difficult to accurately target the target area, and thus limiting the applicable population and scenarios. 5. Inconvenient magnet replacement: In some magnetic massagers, the magnets are mostly fixed by a shaft. If the magnet is demagnetized and needs to be replaced, the disassembly and assembly process is very troublesome and inconvenient for users to replace it themselves. Utility Model Content

[0005] The purpose of this utility model is to provide a main structure for a magnetic therapy massager to solve the above-mentioned technical problems.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: A main structure of a magnetic therapy massager includes a support plate, a drive motor, and a magnetic therapy massage assembly. The drive motor is fixedly mounted on the back of the support plate, and its power shaft passes through the middle of the support plate. The magnetic therapy massage assembly includes a rotating frame and a first magnetic block and a second magnetic block fixed at both ends of the rotating frame. The middle part of the rotating frame is fixedly assembled to the end of the power shaft. The angle α between the line AB connecting the center point A of the power shaft and the center point B of the first magnetic block and the line AC connecting the center point A of the power shaft and the center point C of the second magnetic block is 150°-180°. The diameter of the first magnetic block is smaller than the diameter of the second magnetic block.

[0007] Preferably, the angle α between the line AB connecting the center point A of the power shaft and the center point B of the first magnetic block and the line AC connecting the center point A of the power shaft and the center point C of the second magnetic block is 160°.

[0008] Preferably, the diameter of the first magnetic block is 24 mm; the diameter of the second magnetic block is 33 mm.

[0009] Preferably, a plurality of shock-absorbing rubber columns are fixedly installed on the back of the support plate; the shock-absorbing rubber columns are distributed around the drive motor.

[0010] Preferably, the support plate has a plurality of assembly holes around its perimeter.

[0011] Beneficial effects: Compared with the prior art, the advantages of this utility model are: 1. The magnet layout has been optimized, and the two magnetic blocks have a wider magnetic field distribution, which enhances the uniformity of the magnetic field, covers a wider range, has a larger contact area, and improves the local magnetic field strength. The larger magnetic block has a larger total magnetic moment (magnetization intensity × volume) and a higher magnetic flux (B × area) due to the greater total amount of material. It has stronger magnetic field penetration and performs better in long-distance or large-scale applications. It can penetrate deep into muscles, bones and internal organs to promote blood circulation and cell metabolism in deep tissues. It is especially suitable for chronic diseases that require overall regulation. 2. Four shock-absorbing rubber pillars are fixedly installed on the back of the support plate. These pillars are distributed around the drive motor and effectively absorb the high-frequency vibration energy of the massage head during operation, reducing the amplitude of vibration transmitted upwards to the handheld part. This prevents fatigue or numbness in the user's hand due to prolonged gripping, isolates the handheld part from shaking, and allows the vibration of the lower part (massage head) to act more stably on the body, enhancing the controllability of the massage depth and ensuring precise output of magnetic field strength (e.g., 0.1-0.3T) and vibration frequency. Furthermore, the shock-absorbing rubber pillars reduce mechanical impact on the drive motor and magnet components, preventing loosening of internal circuit solder joints or wear of components due to vibration.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example:

[0015] Reference Figure 1-3 The main structure of the magnetic therapy massager described in this embodiment includes a support plate 1, a drive motor, and a magnetic therapy massage assembly. The drive motor is fixedly installed on the back of the support plate 1, and its power shaft 4 passes through the middle of the support plate 1. The magnetic therapy massage assembly includes a rotating frame 6 and a first magnetic block 5 and a second magnetic block 7 embedded and fixed at both ends of the rotating frame 6. The two magnetic blocks have a wider magnetic field distribution, enhancing magnetic field uniformity, covering a wider range, and having a larger contact area, thus increasing the local magnetic field strength. The larger magnetic block has a larger total material content, a larger total magnetic moment (magnetization intensity × volume), and a higher magnetic flux (B × area), resulting in stronger magnetic field penetration. It performs better in long-distance or large-scale applications, and can penetrate deep into muscles, bones, and internal organs, promoting blood circulation and cell metabolism in deep tissues, making it especially suitable for chronic diseases that require overall regulation.

[0016] The rotating frame 6 is fixedly mounted to the end of the power shaft 4 at its center. The angle α between the line AB connecting the center point A of the power shaft 4 and the center point B of the first magnetic block 5 and the line AC connecting the center point A of the power shaft 4 and the center point C of the second magnetic block 7 is 150°-180°. In this embodiment, the angle α between the lines AB and AC is preferably 160°. Both the first magnetic block 5 and the second magnetic block 7 are flat cylindrical, and the diameter of the first magnetic block 5 is smaller than the diameter of the second magnetic block 7. Specifically, in this embodiment, the diameter of the first magnetic block 5 is 24mm, and the diameter of the second magnetic block 7 is 33mm.

[0017] Four shock-absorbing rubber pillars 2 are fixedly installed on the back of the support plate 1 by screws 9; the shock-absorbing rubber pillars 2 are distributed around the drive motor 3. They effectively absorb the high-frequency vibration energy of the massage head during operation, reducing the amplitude transmitted upwards to the handheld part, preventing fatigue or numbness in the user's hand due to prolonged gripping, isolating the handheld part from shaking, and simultaneously allowing the vibration of the lower part (massage head) to act more stably on the body, enhancing the controllability of the massage depth, and ensuring precise output of magnetic field strength (e.g., 0.1-0.3T) and vibration frequency. Furthermore, the shock-absorbing rubber pillars reduce mechanical impact on the drive motor and magnet components, preventing loosening of internal circuit solder joints or wear of components due to vibration.

[0018] The support plate 1 has several assembly holes 8 around its perimeter. In specific implementation, the aforementioned main structure is assembled onto... Figure 4 Specifically, the magnetic therapy massager shown includes a base 11, a handle 10 fixed to the bottom of the base, and a face mask 12. Each assembly hole 8 of the support plate 1 of the main structure corresponds to each connecting post on the mounting base 13 and is fastened with bolts. Then the face mask 12 is placed on the base 11.

[0019] In use, hold the handle 10 and place the surface of the mask 12 in contact with the area of ​​the body requiring massage therapy. Then, start the drive motor 3, which drives the rotating frame 6, which in turn drives the first magnetic block 5 and the second magnetic block 7 to rotate at high speed. Because the two magnetic blocks are of different sizes, and their center points are arranged in a triangle with the center point of the drive shaft, with the angle α between line AB and line AC being 150°-180° (preferably 160°), a relatively strong vibration is generated when the drive motor 3 drives the two magnetic blocks to rotate at high speed. This allows for simultaneous magnetic therapy and massage therapy on the body. The shock-absorbing rubber columns 2 on the back of the support plate 1 buffer the vibration amplitude of the base 11 and handle 10 during operation, reducing the vibration intensity of the base 11 and handle 10.

Any equivalent structures made using the contents of this utility model's specification and drawings, whether directly or indirectly applied to other related technical fields, are also within the scope of this utility model's patent protection.
