Description

Technical Field

[0001] This invention relates to the field of massager technology, and more specifically, to a swing-type electric massager with magnetic protection function. Background Technology

[0002] With modern people placing increasing emphasis on health management, more and more users are turning to massage devices to promote meridian flow, relieve muscle tension, and thus reduce physical and mental fatigue. Currently, common muscle relaxation tools on the market mainly include fascia guns, foam rollers, massage chairs, and various portable massagers.

[0003] Fascia guns and foam rollers are common self-relaxation tools. Foam rollers require the user to press their own weight onto the roller and actively move their body to achieve a rolling massage, while fascia guns require the user to hold and move them along the muscle groups. Both rely on manual force and continuous operation, resulting in time-consuming and laborious operation, and difficulty in fully covering the back and front muscles. While massage chairs offer automated massage, allowing users to relax simply by lying down, their massage mechanisms are fixed within the backrest and seat cushion, making it difficult to effectively target the front muscles. Furthermore, due to size limitations, the massage heads have limited depth of penetration, failing to reach deep muscle tissue.

[0004] It's worth noting that most existing rolling massagers, whether foam rollers, fascia guns, or electric massage sticks, only offer simple physical massage functions. Their working principle is limited to mechanically stimulating muscles through rolling or vibration, resulting in relatively limited functionality. While physical massage can relieve muscle tension to some extent, it lacks the synergistic effect of auxiliary therapies such as magnetic therapy, making it difficult to achieve multiple health benefits such as promoting blood circulation and regulating the body's biomagnetic field while simultaneously relaxing muscles. Summary of the Invention

[0005] The purpose of this invention is to provide a swing-type electric massager with magnetic protection function to solve the problems mentioned in the background art.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a axial pendulum kneading electric massager with magnetic protection function, comprising a roller, a drive seat connected to both ends of the roller, a drive unit provided inside the drive seat, a traveling gear and a rolling gear respectively provided at both ends of the drive seat, a traveling component linked with the traveling gear and a massage drive component linked with the rolling gear respectively provided on the drive seat, the traveling component rotating relative to the drive seat under the drive of the traveling gear, the massage drive component being sleeved on the outside of the roller and driven by the rolling gear to rotate circumferentially relative to the roller, at least one set of massage units that can rotate with it is provided between the two sets of massage drive components; a plurality of magnetic therapy elements are arranged axially at intervals inside the roller, the outer contour of the magnetic therapy elements is adapted to the inner wall of the roller, the outer wall of each magnetic therapy element is provided with a plurality of radially outwardly extending elastic protrusions along the circumferential direction, and the roller wall is provided with insertion holes for the elastic protrusions to be inserted at the corresponding positions of each magnetic therapy element.

[0007] By adopting the above technical solution, the walking gear and rolling gear respectively drive the walking component and the massage drive component. The walking component rotates relative to the drive seat under the drive gear, enabling the electric massage stick to move automatically along the support surface. Simultaneously, the massage drive component rotates circumferentially relative to the roller under the drive of the rolling gear, causing the massage unit to rotate synchronously. This achieves coordinated driving of the walking and kneading massage actions by the same drive unit. Furthermore, this application arranges several magnetic therapy components axially spaced inside the roller, and uses a snap-fit ​​structure of elastic protrusions and insertion holes to stably fix the magnetic therapy components inside the roller. This allows users to enjoy the kneading massage while receiving magnetic therapy health benefits, achieving a fusion of massage and magnetic therapy functions. It boasts advantages such as compact structure, high functional integration, and synergistic effects of massage and magnetic therapy.

[0008] A further feature is that the outer wall of the magnetic therapy component is provided with several elastic plates spaced apart along the circumference, the elastic protrusions are fixed on the elastic plates, and the outer wall of the magnetic therapy component is provided with clearance openings corresponding to each elastic plate for the elastic plates to undergo elastic deformation.

[0009] By adopting the above technical solution, an elastic plate is installed on the outer wall of the magnetic therapy component, and elastic protrusions are fixed to the elastic plate. Corresponding clearance openings are provided for the elastic plate to elastically deform. This allows the elastic plate to elastically contract inwards when the magnetic therapy component is inserted into the roller, and then elastically resets after insertion, causing the elastic protrusions to embed into the insertion hole, forming a reliable engagement. This structure ensures a secure connection between the magnetic therapy component and the roller, preventing the component from loosening or falling off due to vibration or external force during use. It also allows users to quickly replace or adjust the arrangement of the magnetic therapy components according to actual needs, improving the product's maintainability and flexibility of use.

[0010] A further configuration is as follows: the drive unit includes a drive motor, a primary worm, a transmission shaft, a primary worm wheel, a secondary worm, and a secondary worm wheel. The output end of the drive motor is connected to the primary worm. The transmission shaft is rotatably mounted in the drive seat. The transmission shaft has a primary worm wheel in the middle that meshes with the primary worm. The two ends of the transmission shaft are coaxially connected to the secondary worm, and the secondary worm meshes with the secondary worm wheels respectively. One of the secondary worm wheels is coaxially connected to the traveling gear, and the other secondary worm wheel is coaxially connected to the rolling gear.

[0011] By adopting the above technical solution, and through a combined transmission structure consisting of a primary worm gear, a primary worm wheel, a drive shaft, a secondary worm gear, and a secondary worm wheel, the power of the drive motor is transmitted to the traveling gear and the rolling gear after being reduced in speed by two stages of worm gears. Worm gear transmission features a large transmission ratio, compact structure, and good self-locking properties, effectively preventing external forces from driving the motor in the opposite direction. This ensures that the electric massager will not slip backward even under the pressure of the user's weight during movement, improving safety and stability.

[0012] A further configuration is that the drive base includes a mounting cylinder extending in the direction of the roller, and both ends of the roller are respectively connected to corresponding connecting seats.

[0013] By adopting the above technical solution, and by setting the drive seat to extend in the direction of the roller to form an installation cylinder, with the two ends of the roller connected to the corresponding connecting seats, rapid assembly between the drive seat and the roller is achieved.

[0014] A further configuration is as follows: the walking assembly includes an outer walking wheel and an inner walking wheel, the inner walking wheel is fixed inside the outer walking wheel, and the inner walking wheel is sleeved outside the drive seat. The inner wall of the inner walking wheel is provided with an internal gear ring, and the walking gear meshes with the internal gear ring.

[0015] By adopting the above technical solution, the walking assembly is configured with a double-layer structure of an outer walking wheel and an inner walking wheel. The inner walking wheel is fixed inside the outer walking wheel and sleeved outside the drive seat. The inner wall of the inner walking wheel has an internal gear ring that meshes with the walking gear, so that when the walking gear drives the internal gear ring, it drives the entire walking assembly to rotate synchronously. This structure places the drive mating surface inside, effectively preventing foreign objects from entering the meshing area and improving transmission reliability. At the same time, the outer walking wheel can be made of soft and wear-resistant material, which not only ensures quiet operation but also enhances the friction between the wheel and the support surface, preventing slippage.

[0016] A further configuration is as follows: the massage drive assembly includes an internal gear frame and a fixed bushing. The internal gear frame is sleeved outside the drive seat, and the fixed bushing is sleeved outside the roller and connected to the internal gear frame. An internal gear ring is provided on the inner wall of the internal gear frame, and the rolling gear meshes with the internal gear ring.

[0017] By adopting the above technical solution, the massage drive assembly is configured as a combination of an inner gear frame and a fixed bushing. The inner gear frame is fitted outside the drive seat and has an inner gear ring on its inner wall that meshes with the rolling gear. The fixed bushing is fitted outside the roller and connected to the inner gear frame. This achieves the synchronous rotation of the massage unit by the fixed bushing when the rolling gear drives the inner gear frame to rotate. This structure separates the drive mechanism from the massage unit, ensuring that the rotational movement of the massage unit is not affected by the roller itself, guaranteeing the independence and stability of the massage action, and facilitating the modular assembly and replacement of the massage unit.

[0018] A further configuration is as follows: the massage unit is provided in at least two sets and arranged along the axial direction of the roller. Each set of the massage unit includes an eccentric roller and a kneading roller. The kneading roller is sleeved outside the eccentric part of the eccentric roller. Adjacent eccentric rollers are inserted into each other, and the fixed bushing is inserted into the corresponding eccentric roller.

[0019] By adopting the above technical solution, and by setting the massage units into at least two groups arranged along the roller axis, each massage unit includes an eccentric roller and a kneading roller sleeved outside the eccentric part. Adjacent eccentric rollers are interlocked, and the fixed bushing is interlocked with the corresponding eccentric roller, thus realizing the coordinated rotation of multiple massage units on the roller axis. During the rotation, the eccentric roller drives the kneading roller to produce eccentric oscillation, forming a massage effect similar to manual kneading. The axial arrangement of multiple massage units can cover a wider range of muscle groups, improving the uniformity and comfort of the massage. Attached Figure Description

[0022] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-9 As shown, this invention discloses an axially swinging kneading electric massager with magnetic protection function, including a roller 1, a drive seat 2 connected to both ends of the roller 1, a drive unit 3 inside the drive seat 2, a traveling gear 4 and a rolling gear 5 respectively at both ends of the drive seat 2, a traveling component linked with the traveling gear 4 and a massage drive component 6 linked with the rolling gear 5 respectively on the drive seat 2, the traveling component rotates relative to the drive seat 2 under the drive of the traveling gear 4, the massage drive component 6 is sleeved on the outside of the roller 1 and is driven by the rolling gear 5 to rotate circumferentially relative to the roller 1, at least one set of massage units 7 that can rotate with it is provided between the two sets of massage drive components 6; a plurality of magnetic therapy elements 26 are arranged axially at intervals inside the roller 1, the outer contour of the magnetic therapy elements 26 is adapted to the inner wall of the roller 1, and a plurality of radially outwardly extending elastic protrusions 17 are provided on the outer wall of each magnetic therapy element 26 along the circumferential direction, and the roller 1 has insertion holes 18 corresponding to each magnetic therapy element 26 for the elastic protrusions 17 to be inserted.

[0025] By setting the walking gear 4 and rolling gear 5 to drive the walking component and massage drive component 6 respectively, the walking component rotates relative to the drive seat 2 under the drive of the walking gear 4, realizing the automatic movement of the electric massage stick along the support surface. At the same time, the massage drive component 6 rotates circumferentially relative to the roller 1 under the drive of the rolling gear 5, driving the massage unit 7 to rotate synchronously. This realizes that the walking action and the kneading massage action are driven by the same drive unit 3. On this basis, this application arranges several magnetic therapy components 26 axially spaced inside the roller 1, and uses the snap-fit ​​structure of the elastic protrusion 17 and the insertion hole 18 to realize the stable fixation of the magnetic therapy components 26 inside the roller 1. This allows the user to enjoy the kneading massage while receiving the magnetic therapy health care effect, realizing the integration of massage function and magnetic therapy function. It has the advantages of compact structure, high functional integration, and synergistic effect of massage and magnetic therapy.

[0026] The improvement of this application lies in setting the walking gear 4 and the rolling gear 5 to drive the walking component and the massage driving component 6 respectively, so that the same driving unit 3 can output walking power and massage power simultaneously. Driven by the walking gear 4, the walking component rotates relative to the driving seat 2, realizing the automatic movement of the electric massage stick along the support surface (such as a yoga mat or bed). Driven by the rolling gear 5, the massage driving component 6 rotates circumferentially relative to the roller 1 and drives the massage unit 7 to rotate synchronously, thereby achieving coordinated linkage between walking and kneading massage movements. Users can achieve deep relaxation of multiple muscle groups throughout the body simply by lying down. In this application, the magnetic therapy component 26 can adopt magnetic components with magnetic field generation functions, such as permanent magnets, magnets, or electromagnetic generating elements, which can exert magnetic therapy effects on specific parts of the human body through their own generated magnetic fields, promoting local blood circulation, regulating the human body's biomagnetic field, and relieving muscle fatigue. As a mature commercially available product, the magnetic field strength, magnetic pole arrangement, and magnetic therapy principle of the magnetic therapy component 26 are well known to those skilled in the art, and this invention does not impose any particular limitations on them.

[0027] The improvement in this application does not lie in simply increasing the number of massage heads or changing their shape, nor in simply replacing the drive motor 8 or the control circuit, nor in simply adjusting the position or replacing the material of a component in an existing massage device. Rather, it lies in integrating the walking and massage functions into the same drive unit 3 at the transmission structure level. Through a two-stage worm gear transmission layout, a single power source achieves coordinated drive of two sets of actuators, fundamentally solving the technical problem that traditional massage devices must rely on manual force or cannot simultaneously perform walking and massage. The outer wall of the magnetic therapy component 26 is provided with a plurality of elastic plates 16 spaced apart along the circumference. The elastic protrusions 17 are fixed on the elastic plates 16. The outer wall of the magnetic therapy component 26 is provided with clearance openings 15 corresponding to each elastic plate 16 for the elastic plates 16 to undergo elastic deformation.

[0028] By providing an elastic plate 16 on the outer wall of the magnetic therapy component 26, fixing an elastic protrusion 17 to the elastic plate 16, and correspondingly providing a clearance opening 15 for the elastic plate 16 to elastically deform, the elastic plate 16 can elastically contract inward when the magnetic therapy component 26 is inserted into the roller 1. After reaching its final position, it elastically resets, allowing the elastic protrusion 17 to embed into the insertion hole 18 to form a reliable engagement. This structure not only ensures a firm connection between the magnetic therapy component 26 and the roller 1, preventing the magnetic therapy component 26 from loosening or falling off due to vibration or external force during use, but also allows users to quickly replace or adjust the arrangement of the magnetic therapy component 26 according to actual needs, improving the maintainability and flexibility of the product.

[0029] The drive unit 3 includes a drive motor 8, a primary worm 9, a transmission shaft 10, a primary worm wheel 11, a secondary worm 12, and a secondary worm wheel 13. The output end of the drive motor 8 is connected to the primary worm 9. The transmission shaft 10 is rotatably mounted in the drive seat 2. The transmission shaft 10 has a primary worm wheel 11 in the middle that meshes with the primary worm 9. The two ends of the transmission shaft 10 are coaxially connected to the secondary worm 12, and the secondary worm 12 meshes with the secondary worm wheel 13 respectively. One of the secondary worm wheels 13 is coaxially connected to the traveling gear 4, and the other secondary worm wheel 13 is coaxially connected to the rolling gear 5.

[0030] By employing a combined transmission structure consisting of a primary worm gear 9, a primary worm wheel 11, a transmission shaft 10, a secondary worm gear 12, and a secondary worm wheel 13, the power of the drive motor 8 is transmitted to the traveling gear 4 and the rolling gear 5 after being reduced in speed by two stages of worm gears. The worm gear transmission features a large transmission ratio, compact structure, and good self-locking properties, effectively preventing external forces from driving the motor 8 in the opposite direction. This ensures that the electric massager will not slip backwards even under the pressure of the user's weight during movement, improving safety and stability.

[0031] The drive base 2 includes a mounting cylinder 14 extending toward the roller 1, with both ends of the roller 1 connected to corresponding connecting seats. By configuring the drive base 2 to extend toward the roller 1 to form the mounting cylinder 14, and with both ends of the roller 1 connected to corresponding connecting seats, rapid assembly between the drive base 2 and the roller 1 is achieved.

[0032] The walking assembly includes an outer walking wheel 19 and an inner walking wheel 20. The inner walking wheel 20 is fixed inside the outer walking wheel 19 and is sleeved on the drive seat 2. The inner wall of the inner walking wheel 20 is provided with an internal gear ring 21, and the walking gear 4 meshes with the internal gear ring 21. By setting the walking assembly as a double-layer structure of outer walking wheel 19 and inner walking wheel 20, with the inner walking wheel 20 fixed inside the outer walking wheel 19 and sleeved on the drive seat 2, and the inner wall of the inner walking wheel 20 provided with an internal gear ring 21 that meshes with the walking gear 4, the walking gear 4 drives the internal gear ring 21 to drive the entire walking assembly to rotate synchronously. This structure places the driving mating surface inside, effectively preventing foreign objects from entering the meshing area and improving transmission reliability. At the same time, the outer walking wheel 19 can be made of soft and wear-resistant material, which not only ensures quiet operation during walking but also enhances the friction between it and the supporting surface, preventing slippage.

[0033] The massage drive assembly 6 includes an inner gear frame 22 and a fixed bushing 23. The inner gear frame 22 is sleeved on the drive seat 2, and the fixed bushing 23 is sleeved on the roller 1 and connected to the inner gear frame 22. The inner wall of the inner gear frame 22 is provided with an inner gear ring 21, and the rolling gear 5 meshes with the inner gear ring 21.

[0034] By configuring the massage drive assembly 6 as a combination of an inner gear frame 22 and a fixed bushing 23, the inner gear frame 22 is fitted outside the drive base 2 and has an inner gear ring 21 on its inner wall that meshes with the rolling gear 5. The fixed bushing 23 is fitted outside the roller 1 and connected to the inner gear frame 22, so that when the rolling gear 5 drives the inner gear frame 22 to rotate, the fixed bushing 23 drives the massage unit 7 to rotate synchronously. This structure separates the drive mechanism from the massage unit 7, so that the rotational movement of the massage unit 7 is not affected by the roller 1 itself, ensuring the independence and stability of the massage action, while also facilitating the modular assembly and replacement of the massage unit 7.

[0035] The massage units 7 are provided in at least two sets and arranged along the axial direction of the roller 1. Each set of massage units 7 includes an eccentric roller 24 and a kneading roller 25. The kneading roller 25 is sleeved on the eccentric part of the eccentric roller 24. Adjacent eccentric rollers 24 are interlocked with each other, and the fixed bushing 23 is interlocked with the corresponding eccentric roller 24. By setting the massage units 7 in at least two sets and arranging them along the axial direction of the roller 1, each set of massage units 7 includes an eccentric roller 24 and a kneading roller 25 sleeved on the eccentric part, adjacent eccentric rollers 24 are interlocked with each other, and the fixed bushing 23 is interlocked with the corresponding eccentric roller 24, the linkage rotation of multiple sets of massage units 7 on the axis of the roller 1 is realized. During the rotation, the eccentric roller 24 drives the kneading roller 25 to produce eccentric oscillation, forming a massage effect similar to manual kneading; the axial arrangement of multiple sets of massage units 7 can cover a wider range of muscle groups, improving the uniformity and comfort of the massage.

[0036] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
