Description

Technical Field

[0001] This invention relates to the field of massage hammer technology, and more specifically, to a passive magnetic reciprocating vibration device. Background Technology

[0002] Handheld massage hammers are portable health and wellness devices commonly used in daily life, home health maintenance, office leisure, and sports rehabilitation. They are widely used for relaxation and care of various muscle groups, including the shoulders, neck, back, legs, and arms. Through physical tapping and pressing stimulation, they can effectively relieve muscle stiffness, alleviate body aches and fatigue, unblock meridians, and improve local blood circulation. Due to their small size, lightweight design, ease of use, and lack of location restrictions, they have become a widely used health and wellness product in homes, offices, and outdoor recreational settings.

[0003] Currently, most handheld massage hammers on the market have a relatively simple overall structure, consisting only of an outer shell, a handle, and end massage heads. They are all manually operated, and prolonged continuous massage can easily cause arm pain and wrist fatigue, resulting in high labor intensity and making it difficult to achieve long-term relaxation therapy. The effect of multiple vibration massages with a single hammer strike can solve the above problems. However, traditional vibration mechanisms are mostly actively driven, relying on batteries or external power supplies to operate. They require auxiliary structures such as electronic control components, power supply lines, and charging modules, resulting in a complex overall structure. At the same time, they are limited by battery life and power supply conditions, making them inconvenient for long-term outdoor use or use in environments without power. Their applicable scenarios are very limited. Furthermore, when the electric drive vibration structure is working, the motor operation and gear transmission will generate significant mechanical noise. The operation of the electromagnetic coil also poses electromagnetic interference problems. Moreover, the high-speed moving transmission components suffer from severe friction wear over time, making them prone to jamming and malfunctions. The overall lifespan of the device is short, and the cost of maintenance and replacement is high.

[0004] Therefore, we have made improvements to this and proposed a passive magnetic reciprocating vibration device. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, the purpose of the present invention is to provide a passive magnetic reciprocating vibration device.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows: A passive magnetic reciprocating vibration device includes a circular sleeve, with sealing end caps movably disposed at both ends of the circular sleeve. A collar is rotatably disposed on the outer wall of each of the two sealing end caps. A magnetic ball is movably disposed at the center of the inner wall of the circular sleeve. A uniform plate is slidably disposed on both sides of the inner wall of the circular sleeve. A spring is fixedly disposed on the side of each of the two uniform plates that are separated from each other.

[0007] As a preferred technical solution of this application, threaded portions are provided at both ends of the outer wall of the cylindrical sleeve, and the inner walls of the two collars are respectively threadedly engaged with the two threaded portions. As a preferred technical solution of this application, the diameters of the two uniform plates and the two magnetic balls are all smaller than the inner diameter of the circular sleeve; As a preferred technical solution of this application, one end of each of the two springs is fixedly connected to two sealing end caps, and both springs are made of 304 stainless steel. As a preferred technical solution of this application, both sealing end caps are made of low carbon steel with galvanized surface, the round sleeve is made of 304 stainless steel, a TPFE bushing is fixedly provided on the inner wall of the round sleeve, and both uniform plates are made of polyoxymethylene. As a preferred technical solution of this application, a groove is provided at the center of the opposite side of the two sealing end caps, and the radius of curvature of the two grooves is greater than the diameter of the magnetic ball.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes a circular sleeve, a sealing end cap, a collar, a spring, a uniform plate, and a magnetic ball to form a passive magnetic reciprocating vibration structure. It requires no electricity or motor control; stable and continuous reciprocating vibration is achieved solely through magnetic force and spring elastic reset. The TPFE bushing on the inner wall of the circular sleeve minimizes sliding resistance, provides wear and rust resistance, and extends service life. The groove on the inner side of the sealing end cap gathers and disperses magnetic lines of force, enhancing magnetic concentration and increasing local magnetic flux density. Simultaneously, the threaded engagement between the collar and the threaded part of the circular sleeve facilitates convenient assembly and disassembly, and ensures low-noise and stable operation. It can be directly integrated into a massage hammer, generating continuous vibration with a single application of force, improving the massage experience and therapeutic effect while reducing subsequent replacement and maintenance costs.

[0011] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0012] Please see Figures 1-4 As shown, the present invention provides a technical solution: a passive magnetic reciprocating vibration device, including a circular sleeve 1, with sealing end caps 2 movably disposed at both ends of the circular sleeve 1, and collars 3 rotatably disposed on the outer walls of the two sealing end caps 2, a magnetic ball 7 movably disposed at the center of the inner wall of the circular sleeve 1, and equalizing plates 6 slidably disposed on both sides of the inner wall of the circular sleeve 1, with springs 5 ​​fixedly disposed on the side of the two equalizing plates 6 that are separated from each other.

[0013] Furthermore, by movably setting magnetic balls 7 and uniform plates 6 inside the cylindrical sleeve 1, and combining them with the sealing end cap 2, collar 3 and spring 5 to form an integral structure, the effect of passive magnetic reciprocating vibration is achieved. It should be noted that the impact force and vibration frequency can be adjusted by changing the size and shape of the cylindrical sleeve 1 and the magnetic strength and shape of the magnetic ball 7, thus achieving the energy-saving effect brought about by the passive design.

[0014] In the preferred embodiment of this technical solution, please refer to Figures 1-2 As shown, threaded portions 4 are provided at both ends of the outer wall of the cylindrical sleeve 1, and the inner walls of the two collars 3 are threadedly engaged with the two threaded portions 4 respectively.

[0015] Furthermore, the sealing end cap 2 is screwed and locked by the threaded parts 4 at both ends of the inner wall of the collar 3 and the outer wall of the cylindrical sleeve 1, which facilitates assembly and maintenance and replacement of the magnetic ball 7.

[0016] In the preferred embodiment of this technical solution, please refer to Figures 1-2 As shown, the diameters of the two uniform plates 6 and the two magnetic balls 7 are all smaller than the inner diameter of the circular sleeve 1.

[0017] Furthermore, by setting the diameters of both the uniform plate 6 and the magnetic ball 7 to be smaller than the inner diameter of the cylindrical sleeve 1, the uniform plate 6 and the magnetic ball 7 can slide smoothly along the inner wall of the cylindrical sleeve 1, thereby avoiding jamming during movement.

[0018] In the preferred embodiment of this technical solution, please refer to Figures 1-2 As shown, one end of each of the two springs 5 ​​is fixedly connected to one of the two sealing end caps 2, and both springs 5 ​​are made of 304 stainless steel.

[0019] Furthermore, by fixing one end of the spring 5 to the sealing end cap 2 and using 304 stainless steel, the spring 5 has stable elastic support and corrosion resistance, thereby ensuring the stability of the elastic reset of the reciprocating motion and the stability of long-term use.

[0020] In the preferred embodiment of this technical solution, please refer to Figures 1-2 As shown, both sealing end caps 2 are made of low-carbon steel with galvanized surface, the round sleeve 1 is made of 304 stainless steel, the inner wall of the round sleeve 1 is fixed with a TPFE bushing, and both uniform plates 6 are made of polyoxymethylene.

[0021] Furthermore, by using appropriate special materials for the sealing end cap 2, the circular sleeve 1, and the uniform plate 6, and matching the TPFE bushing on the inner wall of the circular sleeve 1, the sliding friction resistance is reduced, thereby improving the smoothness of movement and the wear resistance and rust prevention performance of the structure, thus extending the service life.

[0022] In the preferred embodiment of this technical solution, please refer to Figures 3-4 As shown, grooves 8 are provided at the center of opposite sides of the two sealing end caps 2, and the radii of curvature of the two grooves 8 are both greater than the diameter of the magnetic ball 7.

[0023] Furthermore, by opening a groove 8 with a radius of curvature larger than the diameter of the magnetic ball 7 on the inner side of the sealing end cap 2, the magnetic lines of force are gathered and the magnetic force concentration is enhanced, thereby increasing the local magnetic flux density. This allows the sealing end cap 2, which is relatively flat, to increase the attraction force and prevent the magnetic ball 7 from becoming unbalanced due to magnetic pole offset.

[0024] Working principle: When the massage hammer is used, it applies initial kinetic energy to the magnetic ball 7, causing it to move to one side along the cylindrical sleeve 1. When the magnetic ball 7 approaches the sealing end cap 2 on that side, it continues to move under the action of non-contact magnetic attraction, thereby compressing the spring 5 until it reaches its limit position. When the elastic force of the spring 5 is greater than the force exerted by the magnetic force on the magnetic ball 7, the spring 5 releases the accumulated elastic potential energy. Through the equalizing plate 6, the force of the spring 5 can be evenly transmitted to the magnetic ball 7, thereby pushing the magnetic ball 7 to move to the other side. By utilizing the alternating action of the magnetic force and the elastic force of the spring 5, the magnetic ball 7 is driven to make short-term reciprocating oscillations within the cylindrical sleeve 1, thus achieving the effect of continuous vibration with a single application of force, improving the massage experience and therapeutic effect.
