Description

Technical Field

[0001] This utility model relates to a massage device, and more particularly to a multi-mode massage wheel leg massage device driven by a belt or chain. Background Technology

[0002] A leg massager is a device designed to relieve leg muscle fatigue and promote blood circulation. It typically uses methods such as airbag massage, roller massage, or vibration massage to simulate human hand massage movements. Inflated airbags compress and relax the legs; rollers knead the muscles; and vibration massage stimulates the muscles through high-frequency vibrations. These devices are generally equipped with multiple massage modes and intensity adjustments to meet the needs of different users. Their shape often conforms to the curves of the leg, making them suitable for use in homes, offices, or massage parlors, providing users with a convenient and comfortable leg massage experience.

[0003] Traditional massage chairs often use airbag compression or unidirectional rollers for their calf massage units. While these methods offer some massage benefits, they have several drawbacks. Airbag compression can result in uneven pressure, limited relief for tense muscles, and an inability to precisely target specific pain points. Unidirectional rollers struggle to fully cover the calf muscles, easily missing areas, and their limited massage trajectory fails to mimic the complex and varied movements of a human hand, resulting in a less rich and in-depth massage experience that is less effective at relaxing deep muscles. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a multi-mode massage wheel leg massage device driven by a belt or chain that always has a massage component in contact with the human leg.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-mode massage wheel leg massage device driven by a belt or chain, comprising a massage wheel driven by a drive member to move along the direction of the calf, wherein the outer circumferential surface of the massage wheel is provided with a plurality of massage heads, and further comprising a reciprocating moving member driven by the drive member to rotate, wherein at least two massage wheels are connected to the reciprocating moving member, wherein the reciprocating moving member comprises a massage surface facing the direction of the calf, a rotating surface facing away from the direction of the calf, and alternating surfaces located on both sides of the reciprocating moving member and connecting the massage surface and the rotating surface, wherein when one massage wheel enters the alternating surface from the massage surface, there is a massage wheel entering the alternating surface from the rotating surface.

[0006] The beneficial effects of this invention are as follows: The driving component moves the massage rollers along the calf direction, and the unique design of the reciprocating moving component enables the efficient collaborative work of multiple massage rollers. The multiple massage rollers increase the massage coverage, avoiding the problem of missed areas in traditional massage methods. This solves the deficiency of traditional massage chairs where the single-direction rollers in the calf massage unit cannot fully cover the area. When the massage rollers systematically switch between the massage surface, rotating surface, and alternating surface, they simulate a complex and varied massage trajectory, which contrasts sharply with the single massage trajectory of traditional massage chairs. This allows for more precise application to various parts of the calf muscles, effectively relieving muscle tension, accurately massaging specific pain points, and providing uniform and stable pressure. This overcomes the uneven pressure of traditional airbag compression massage, providing users with a richer, deeper, and more comfortable massage experience. It greatly enhances the massage effect and practicality of the leg massage device, giving it strong competitiveness and broad application prospects in the massage equipment market.

[0007] Furthermore, the reciprocating moving part is strip-shaped, and the alternating surfaces on both sides of the reciprocating moving part have roughly the same length when unfolded. The straight line formed by connecting the centers of the two alternating surfaces is parallel to the massage surface and the rotating surface, respectively.

[0008] The unique design of the reciprocating moving component, featuring a ribbon-like shape and alternating surfaces on both sides, further enhances the performance advantages of the leg massager. The alternating surfaces on both sides are of equal length when unfolded, and the straight line formed by their centers is parallel to the massage surface and the rotating surface. This ensures the stability and regularity of the massage roller during its reciprocating movement. As the massage roller cycles from the massage surface to the alternating surface and then to the rotating surface, it maintains a uniform rhythm, ensuring a consistently stable and balanced massage intensity on the calf muscles. This avoids inconsistent intensity and effectively solves the problem of uneven pressure in traditional airbag massage. Simultaneously, the regular movement trajectory ensures that the massage roller can comprehensively and systematically cover the calf muscles, preventing any omissions or unreasonable overlapping massage areas. Compared to the limitations of traditional single-direction rollers that struggle to provide comprehensive coverage, this design significantly improves the comprehensiveness and precision of the massage. Overall, it provides users with a more comfortable, deep, and efficient massage experience, significantly improving the quality and practicality of the leg massager and enhancing its competitiveness in the massage equipment market.

[0009] Furthermore, the diameter of the massage roller is such that it disengages from the calf just as it reaches the center of the alternating surface.

[0010] The massage roller disengages from the calf precisely when it reaches the center of the alternating surface, a design that makes the massage process more scientific and rational. As the massage roller moves from the massage surface to the alternating surface, it continuously and thoroughly massages the calf, effectively covering the calf muscles and avoiding the problem of traditional massage methods missing certain areas. And when it disengages from the calf at the center of the alternating surface, another massage roller has also reached the center of the alternating surface, thus making contact with the calf and avoiding any massage gaps, thereby improving the quality of the massage.

[0011] Furthermore, the reciprocating moving parts are symmetrically arranged on both sides of the massage wheel, and each side of the massage wheel is provided with a linkage component. The linkage component includes a hinge block hinged on the same hinge axis. The center of the hinge axis coincides with the center of the massage wheel and forms a fixed connection with the massage wheel.

[0012] The symmetrically distributed reciprocating moving parts ensure even force distribution on both sides of the massage rollers, allowing for more stable movement along the calf during operation. This effectively prevents the massage rollers from shifting or wobbling due to uneven force distribution, ensuring that the massage intensity is consistently and accurately applied to the calf muscles, overcoming the problem of uneven intensity in traditional massage methods. Furthermore, the linkage components on both sides of each massage roller are hinged to a hinge shaft that coincides with and is fixedly connected to the center of the massage roller, further enhancing the synergy between the massage rollers and the reciprocating moving parts. This allows the massage rollers, driven by the reciprocating moving parts, to more flexibly and smoothly complete the cyclical motion from the massage surface to the alternating surface and then to the rotating surface.

[0013] Furthermore, the hinge block is provided with a connecting hole, and a connector is provided in the connecting hole to achieve fixation with the reciprocating moving part.

[0014] The connecting holes and connectors on the hinge block further optimize the overall performance of the leg massager. The connectors within the connecting holes secure the massager to the reciprocating moving parts, creating a stable and reliable connection structure. This connection method ensures a tight fit between the massage rollers and the reciprocating moving parts, allowing for precise power transmission during operation. The massage rollers accurately follow the movement trajectory of the reciprocating moving parts, performing massage actions stably on the massage surface, alternating surface, and rotating surface, preventing loosening or disengagement and effectively guaranteeing the continuity and stability of the massage process. Simultaneously, this adjustable connection method facilitates equipment maintenance and adjustment. When replacement or repair of the massage rollers or reciprocating moving parts is required, the connectors can be easily disassembled for the corresponding operations, reducing maintenance costs and difficulty and extending the equipment's lifespan.

[0019] This utility model embodiment provides a multi-mode massage wheel leg massage device driven by a belt or chain, such as... Figure 1 - As shown in Figure 4: The device includes a drive unit 1 located at the center of the leg massager, and multiple massage heads 21 of different styles are provided on both sides of the drive unit 1 (these massage heads can naturally be such as...). Figure 4 The massage rollers 2 (which are cylindrical and concave in shape, but can also be convex in shape or other shapes) are shown. The reciprocating moving parts 22 are symmetrically arranged on both sides of the multiple massage rollers 2 on this side. The linkage assembly 3 is used to connect the reciprocating moving parts 22 and the massage rollers 2. The driving part 1 is a drive motor. Both ends of the driving part 1 are connected to the drive shaft 12. Two transmission teeth 11 are provided on each side of the drive shaft. The reciprocating moving parts 22 are belts and are located on both sides of the massage rollers 2. The belts have meshing teeth 224 on the inner side of the belts relative to the transmission teeth 11 so as to drive the reciprocating moving parts 22 to rotate when the drive shaft rotates.

[0020] Each massage roller 2 has a linkage component 3 fixed to the reciprocating moving part 22 on both sides. The linkage component 3 includes a hinge block 32 hinged to the same hinge shaft 31. The hinge block 32 has a connecting hole 321 that fixes the hinge block 32 and the reciprocating moving part 22 through a connector (not shown in the figure). The center of the hinge shaft 31 coincides with the center of the massage roller 2 and forms a fixed connection with the massage roller 2.

[0021] The reciprocating moving part 22 includes a massage surface 221 facing the calf, a rotating surface 222 facing away from the calf, and an alternating surface 223 located on both sides of the reciprocating moving part 22 and connecting the massage surface 221 and the rotating surface. The diameter of each massage roller 2 is such that the massage roller 2 disengages from the calf just when it reaches the center of the alternating surface 223.

[0022] The following describes the usage process of this embodiment with two massage rollers 2 arranged on one side of the drive component 1: When one massage roller 2 moves from one end of the massage surface 221 to the other end, the other massage roller 2 moves from one end of the rotating surface 222 to the other end. When the massage roller 2 moving on the massage surface 221 enters the alternating surface 223, the massage roller 2 moving on the rotating surface 222 also simultaneously enters the alternating surface 223. When both reach the center of the alternating surface 223, the massage roller 2 that entered the alternating surface 223 from the massage surface 221 just disengages from the user's calf, and the massage roller 2 that entered the alternating surface 223 from the rotating surface 222 just comes into contact with the user's calf, thus achieving the effect of alternating massage. The above process alternates to achieve a cyclical massage effect.

[0023] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
