Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, specifically to a roller massager. Background Technology

[0002] Yoga columns were originally used to assist patients in balance training and muscle relaxation. They were mostly made of high-density polyethylene (PE) foam and had a simple structure (smooth cylinder). With the popularization of yoga, Pilates and other exercises, their function gradually expanded to self-fascia relaxation, becoming a common tool for relaxing muscles and improving flexibility before and after exercise. The need for deep muscle relaxation among athletes and fitness enthusiasts has driven the development of yoga columns from a single smooth cylinder to structures with bumps, ridges, hollow parts, and segmented designs to adapt to the massage pressure of different parts (such as the back, thighs, shoulders and neck). However, most yoga columns require the body to rotate to rotate, resulting in low flexibility.

[0003] A rotatable massage yoga column is disclosed in patent document CN219022170U, which includes a connecting shell, a rotating massage component, a drive shaft, a first roller, a second roller, and a massage sleeve. The rotating massage component and the drive shaft are disposed inside the connecting shell. The rotating massage component drives the drive shaft, one end of which extends out of the connecting shell and connects to the first roller, and the other end of which extends out of the connecting shell and connects to the second roller. The massage sleeve is wrapped around the outside of the connecting shell. The rotating massage component drives the drive shaft to rotate. This structure improves the flexibility of the yoga column and provides a better massage experience. However, its drive device uses a worm gear, reduction gear, and bevel gear structure, which is complex and, as is well known, prone to failure. Moreover, the drive device and transmission device are located on the shell, and they rotate with the shell during operation. If the weight is uneven at different positions on the circumference of the shell, centrifugal force will cause impact during rotation, resulting in a poor experience. In addition, this solution can only massage muscles and cannot whiten or remove wrinkles and blemishes from the skin, making its function limited.

[0004] Patent document CN208823896U discloses a phototherapy yoga column, including a rollable outer shell, at least a portion of which is transparent. The outer shell is hollow, and a lamp panel and a power supply device for powering the lamp panel are installed inside. Light-emitting tubes are mounted on the lamp panel, facing the transparent outer shell. The power supply device includes a control board, a power switch, and a battery. The control board is connected to the battery, lamp panel, and power switch via conductive wires. A balancing device is also installed inside the outer shell, and the lamp panel is fixedly mounted on the balancing device. It features a phototherapy lamp panel, allowing for LED phototherapy while using the yoga column for self-exercise, stretching fascia, relieving fatigue, and relaxing muscle groups. However, its surface lacks a rotating massage function, preventing deep muscle massage. Summary of the Invention

[0005] The present invention aims to solve the technical problem that existing yoga pillars have complex structures, limited functions, and generate impact during use, making it impossible to simultaneously provide light therapy and massage to the human body.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a roller massager, comprising a main housing and a massage component, the massage component being rotatably fitted on the outside of the main housing, a drive device being provided inside the main housing; a transmission device being provided between the main housing and the massage component, the drive device driving the massage component to rotate through the transmission device; and a phototherapy component for phototherapy being provided on the main housing.

[0007] This design incorporates a phototherapy component within the main housing and a massage component mounted on the outside of the main housing. A drive mechanism rotates the massage component around the main housing, providing deep massage to the muscles and relieving muscle soreness. Simultaneously, the phototherapy component can be activated to provide phototherapy to the skin while simultaneously massaging the muscles. Alternatively, either muscle massage or phototherapy can be used alone, offering a wider range of applications and more options for users. The drive mechanism is simple in structure and located inside the main housing; it does not rotate during operation, preventing impact and enhancing the user experience. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1 to 5 As shown, a roller massager includes a main housing 1 and a massage component 2, the massage component 2 being rotatably fitted on the outside of the main housing 1; inside the main housing 1 is a drive device 31 for driving the massage component 2 to rotate, and a phototherapy component 4 for phototherapy.

[0019] In this embodiment, the main housing 1 includes an upper housing 11 and a lower housing 12. The upper housing 11 and the lower housing 12 together form a placement space. The drive device 31 is disposed in the placement space, and a power supply 6 is also disposed in the placement space. The power supply 6 is electrically connected to the drive device 31. The upper housing 11 and the lower housing 12 are connected by snaps or screws to form a detachable structure. The drive device 31, the power supply 6, and the phototherapy component 4 can all be disassembled and replaced independently. If a failure occurs, the entire unit does not need to be scrapped. Individual parts can be replaced, reducing the cost of use.

[0020] like Figures 6 to 7 As shown, a transmission device 5 is provided between the main housing 1 and the massage component 2. The drive device 31 drives the massage component 2 to rotate through the transmission device 5. In this embodiment, the drive device 31 includes a motor 311 and a reducer 312. The transmission device 5 includes two driving gears 51 and a driven member 52. An internal gear ring 521 is provided on the driven member 52. The output shaft of the reducer 312 is connected to the two driving gears 51. The driving gears 51 are located on the inner side, forming an "internal meshing" transmission. Compared with external gear transmission, the radial dimension can be greatly reduced under the same transmission ratio, which is suitable for the slender cylindrical shape of the yoga column and saves internal space to accommodate modules such as the phototherapy component 4 and the power supply 6. The tooth shape of the internal gear ring can achieve high-precision meshing and small transmission error. Combined with the precision gear set of the reducer, it ensures rotational accuracy and avoids noise or vibration caused by transmission gap.

[0021] In this embodiment, output openings 10 are provided on the side of the upper housing 11 and the lower housing 12 near the driven member 52. Two driving gears 51 extend from the output openings 10 of the upper housing 11 and the lower housing 12 respectively and mesh with the internal gear ring 521 of the driven member 52, forming a symmetrical force structure. Compared with single gear drive, it can effectively counteract the radial reaction force during rotation, avoid the driven member 52 from eccentric shaking or jamming, and ensure the smooth rotation under high speed or load. The massage component 2 is connected to the driven member 52 and drives the two driving gears 51 to rotate through the motor 311, thereby driving the driven member 52 to rotate. The massage component 2 is connected to the driven member 52, and the rotation of the driven member 52 further drives the massage component 2 to rotate. When the massage component 2 rotates, the massage protrusions on its surface can form a dynamic pressing trajectory, which can more comprehensively stimulate the muscle fascia compared with the linear rolling of the traditional fixed massage column.

[0022] The drive device 31 of this solution has a simple structure and is located inside the main housing 1. When working, the drive device 31 does not rotate and will not generate impact, which effectively improves the user experience.

[0023] like Figure 7 As shown, the phototherapy component 4 includes an upper lamp plate 41 disposed on the upper housing 11 and a lower lamp plate 42 disposed on the lower housing 12. The upper lamp plate 41 and the lower lamp plate 42 are respectively disposed on the upper housing 11 and the lower housing 12, which can make the phototherapy coverage wider. Both the upper lamp plate 41 and the lower lamp plate 42 are electrically connected to the power supply 6. Multiple lamp beads 40 are disposed on both the upper lamp plate 41 and the lower lamp plate 42. Multiple light-transmitting holes 100 corresponding to the lamp beads 40 are opened on both the upper housing 11 and the lower housing 12. The lamp beads 40 extend from the light-transmitting holes 100, which makes the light more evenly distributed in the massage area. Multiple lamp beads 40 can form a dense light source matrix to avoid blind spots or uneven light intensity.

[0024] like Figure 3 and Figure 5 As shown, the main housing 1 extends to one side to form a first armrest 13, and the other side of the main housing 1 is connected to a second armrest 14. Both the first armrest 13 and the second armrest 14 include a connecting part 101 and a handle part 102. A control board 15 is provided in the handle part 102 of the first armrest 13 and the second armrest 14. The control board 15 is electrically connected to the power supply 6. A button 105 is also provided on the handle part 102. When using the yoga column, the user can control the drive of the motor 311 or the switch of the light panel through the button 105 on the handle part 102. When the user uses the yoga column, both hands need to hold the armrests continuously to control the pressure and rolling direction. At this time, the handle part 102 directly integrates the control button, which can realize the simultaneous holding and operation, without having to frequently release the armrests to find the buttons on the machine body, and avoid the massage position shift or uneven pressure caused by changes in posture.

[0025] like Figure 6 As shown, a bearing connection portion 103 is formed on the side of the connecting portion 101 that connects to the main housing 1. A bearing 7 is fitted onto the bearing connection portion 103. The massage assembly 2 includes a rotating member 21, which is disposed opposite to the driven member 52. The driven member 52 and the rotating member 21 extend outward to form an abutment portion 20. The abutment portion 20 and the bearing connection portion 103 together form a rotating cavity 201, and the bearing 7 is placed inside the rotating cavity 201. The bearing connection portion 103 provides a precise installation position for the bearing 7, enabling the bearing 7 to be accurately positioned in a specific location, ensuring the coaxiality and stability of the entire structure. The bearing connection 103 provides stable support for the rotating component, reducing swaying and offset during rotation. A limiting member 106 is provided on the connection 101, which extends towards the center to form a limiting part 1061. The width of the limiting part 1061 is slightly larger than the width of the rotating component 21 and the driven component 52, so that the rotating component 21 and the driven component 52 can only move or rotate within the range specified by the limiting part 1061 during movement. This ensures the accuracy of their movement trajectory and avoids offset, swaying or misalignment, which helps to improve the stability and reliability of the entire massage assembly 2.

[0026] During installation, first install the limiting member 106 of the connecting part 101 of the first armrest 13, then put the massage component 2 on the outside of the main housing 1 from the side opposite to the first armrest 13, then install the second armrest 14, connect the second armrest 14 to the main housing 1, and finally install the limiting member 106 of the connecting part 101 of the second armrest 14.

[0027] In this embodiment, a fixing member 22 is connected between the rotating member 21 and the driven member 52. Multiple fixing holes 221 are provided on the fixing member 22, and a massage column 23 is rotatably arranged in the fixing holes 221. When using the yoga column, the fixing member 22 rotates around the main housing 1. The user places the massage column 23 on the fixing member 22 against the part that needs to be massaged. Due to the friction of the human body, the massage column 23 rotates in the opposite direction to the fixing member 22. The massage protrusions on the massage column 23 are spaced apart, which allows the massage protrusions to press against the human body and press the muscles. Then, due to the rotation, the gaps between the massage protrusions face the human body. At this time, the pressure of the massage column 23 on the human body disappears. The user does not need to move the entire yoga column to prevent the yoga column from pressing on one part for a long time, which improves the flexibility of the massage.

[0028] Meanwhile, in this embodiment, the fixing member 22 is made of a light-transmitting material, so that the light emitted by the lamp bead 40 on the main housing 1 located below the fixing member 22 can be radiated through the fixing member 22 to perform phototherapy on the human body, so that the yoga column can perform phototherapy on the human skin while massaging the muscles.

[0029] like Figure 8 As shown, the yoga column also includes bases 8 on the left and right sides. A deep fixing groove 81 is formed in the vertical direction of the base 8, and a shallow fixing groove 82 is formed in the horizontal direction of the base 8. The deep fixing groove 81 and the shallow fixing groove 82 are connected. The lower half of the connecting part 101 is located in the deep fixing groove 81, and the handle part 102 is located in the shallow fixing groove 82. The lower half of the connecting part 101 is embedded in the deep fixing groove 81 in the vertical direction. The depth of the deep fixing groove 81 provides sufficient vertical support space, effectively limiting the vertical displacement and swaying of the connecting part 101. When subjected to dynamic loads such as human body pressure and stretching, it ensures a stable connection between the connecting part 101 and the base 8. The handle part 102 is located in the shallow fixing groove 82 in the horizontal direction, and the horizontal direction of the shallow fixing groove 82 restricts the left and right displacement of the handle part.

[0030] like Figure 2 and Figure 9 As shown, the bottom of the base 8 is provided with an adsorption part 83, and an adsorption switch 84 is provided on the outside of the base 8 to control the adsorption state of the adsorption part 83 and the plane. A locking block cavity 85 is provided inside the base 8, and a through hole 851 is provided in the locking block cavity 85 to connect the locking block cavity 85 with the fixing shallow groove 82. A locking block 9 is provided in the locking block cavity 85, and the locking block 9 can move horizontally within the locking block cavity 85. The locking block is provided with a locking part 91, and a locking hole 104 corresponding to the locking part 91 is provided on the part of the handle 102 located in the fixing shallow groove 82. The locking part 91 can extend from the through hole 851 into the fixing shallow groove 82 and into the locking hole 104 to fix the yoga column between the bases 8. A button is provided on the upper side of the base 8. By pressing the button, the locking block 9 can be moved horizontally within the locking block cavity 85, thereby controlling the separation and locking of the handle 102 from the base 8.

[0031] Controlled by the adsorption switch 84, the base 8 can quickly achieve a tight fit with the ground or flat surface, effectively resisting the horizontal thrust (such as the lateral tilting force when the user stretches or twists) or vertical pressure when using the yoga column, avoiding the safety hazards caused by the slippage of the base 8; at the same time, the adsorption part 83 can adsorb the base 8 onto the wall, and then the locking part 91 and the locking hole 104 cooperate to fix the yoga column between the base 8 after it is started. The user can put their back against the massage column 23 to achieve phototherapy massage of the back, making it more convenient to use.

[0032] The above structure, by mounting a massage component 2 on the outside of the main housing 1, and driving the massage component 2 to rotate around the main housing 1 via a drive device 31 to perform a rotational massage on the human body, and the drive device 31 is located inside the main housing 1, the drive device 31 itself does not rotate during operation, and does not generate impact, effectively improving the experience; an upper light panel 41 and a lower light panel 42 are set on the main housing 1, and the light emitted by the upper light panel 41 and the lower light panel 42 is radiated outward through the light-transmitting fixing member 22 to perform phototherapy on the human skin, which allows the yoga column to perform phototherapy on the human skin while massaging the muscles; and the button on the handle 102 can control to perform only muscle massage, only phototherapy, or both simultaneously, making the usage scenarios more diverse.
