Description

Technical Field

[0001] This application relates to the field of massager technology, and more particularly to a leg massager. Background Technology

[0002] Currently, leg massagers are a common health care device widely used in homes, offices, and the rehabilitation medical field. With increasing demands for health and comfort, the types and functions of leg massagers have gradually diversified, evolving from simple mechanical massage to various modes such as electric massage, air pressure massage, and roller massage. Existing leg massagers primarily target the calves, feet, or thighs to relieve muscle fatigue, promote blood circulation, and, to some extent, assist in rehabilitation training.

[0003] Existing leg massage technologies mainly include vibration massage and rolling massage. Vibration massage uses a motor to drive a vibrating component to generate high-frequency vibrations that stimulate leg muscles; or it uses a motor to drive the movement of the massage component to deeply stimulate the muscles and relieve muscle fatigue. The combination of these technologies allows leg massagers to provide a diverse range of massage experiences to meet the needs of different groups of people.

[0004] However, most massagers use multi-axis linkage mechanisms for transmission to achieve the reciprocating motion of the massage head. Because the transmission path of the linkage mechanism is relatively long and involves multiple moving joints, it is prone to jamming due to mechanical friction, assembly errors, or long-term use, affecting the smoothness of the massage. At the same time, because power needs to be transmitted through multiple linkages, energy loss is significant, resulting in relatively low pressure from the massage head and difficulty in providing a deep muscle massage effect. Utility Model Content

[0005] In view of this, it is necessary to provide a leg massager that can provide a better massage to solve the above problems.

[0006] An embodiment of this application provides a leg massager, comprising:

[0007] Base;

[0008] The housing is disposed on the base and has an inner cavity and a through hole formed in the side wall of the housing and communicating with the inner cavity;

[0009] A massage assembly includes a drive component, a transmission component, and a massage component. The drive component is disposed in the inner cavity, the transmission component is disposed on the drive shaft of the drive component, and the massage component is disposed on the transmission component and protrudes from the through hole.

[0010] The transmission component is an integral structure and is eccentrically positioned with the drive component. It is used to push the massage component out through the through hole or retract it into the inner cavity when the drive component is running.

[0011] In at least one embodiment of this application, the transmission member includes a transmission part and a plurality of eccentric parts. The transmission part is disposed on the drive shaft of the drive member and is coaxially arranged with the drive shaft. The massage member is disposed on the eccentric parts, and the transmission part is spaced apart from each of the eccentric parts.

[0012] In at least one embodiment of this application, the housing further includes a fixing part extending inward from the housing, a transmission part disposed on the fixing part, and two adjacent eccentric parts protruding in opposite directions, for the adjacent two massage elements to be alternately pushed out or retracted into the inner cavity through the through hole when the driving member moves.

[0013] In at least one embodiment of this application, the massage member includes an integrally formed first ejector portion, a second ejector portion, and an annular portion, wherein the eccentric portion passes through the axis of the annular portion;

[0014] The first ejector portion and the second ejector portion are positioned opposite each other at both ends of the annular portion, and are used to eject or retract into the inner cavity through the through hole in an alternating manner when the driving member is driven.

[0015] In at least one embodiment of this application, the massage component further includes a flexible member, which is sleeved on the eccentric portion and conforms to the inner surface of the annular portion;

[0016] The massage component also includes a limiting part, which is circumferentially disposed on the inner surface of the annular part. One side of the flexible component abuts against the limiting part to limit the displacement of the flexible component.

[0017] In at least one embodiment of this application, the massage member further includes a massage portion, which is respectively disposed at the end of the first ejector portion and the second ejector portion away from the annular portion, and the massage end of the massage portion has an arc-shaped surface.

[0018] In at least one embodiment of this application, the direction of the massage portion toward the annular portion is defined as a first direction, the projected area of ​​the massage portion along the first direction is a, and the projected areas of the first ejector portion and the second ejector portion along the first direction are b, where a ≥ b.

[0019] In at least one embodiment of this application, the massage member further includes a first adhesive layer and a second adhesive layer, wherein the first adhesive layer is disposed between the flexible member and the eccentric portion, and the second adhesive layer is disposed between the flexible member and the annular portion.

[0020] In at least one embodiment of this application, the housing further includes a partition plate that divides the inner cavity into a first cavity and a second cavity, the driving member is disposed in the first cavity, and the driving shaft of the driving member extends into the second cavity;

[0021] The massage assembly also includes a connector, one end of which is sleeved on the drive shaft of the drive component, and the other end of which is sleeved on the transmission component.

[0022] In at least one embodiment of this application, the fixing part has a wire groove, which is arranged parallel to the transmission part to fix the wire to prevent it from affecting the rotation of the transmission part.

[0023] The leg massager described above utilizes a one-piece transmission mechanism, avoiding the multiple moving joints and transmission paths found in multi-axis linkage mechanisms. This reduces jamming caused by friction. The eccentric arrangement of the one-piece transmission and drive components makes power transmission more direct, reducing energy loss from multiple linkages and providing a more effective deep muscle massage effect. The simplified transmission structure reduces wear between moving parts and losses from long-term use, thereby extending the massager's lifespan. Attached Figure Description

[0031] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0032] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.

[0033] An embodiment of this application provides a leg massager, comprising:

[0034] Base;

[0035] The housing is disposed on the base and has an inner cavity and a through hole formed in the side wall of the housing and communicating with the inner cavity;

[0036] A massage assembly includes a drive component, a transmission component, and a massage component. The drive component is disposed in the inner cavity, the transmission component is disposed on the drive shaft of the drive component, and the massage component is disposed on the transmission component and protrudes from the through hole.

[0037] The transmission component is an integral structure and is eccentrically positioned with the drive component. It is used to push the massage component out through the through hole or retract it into the inner cavity when the drive component is running.

[0038] The leg massager described above utilizes a one-piece transmission mechanism, avoiding the multiple moving joints and transmission paths found in multi-axis linkage mechanisms. This reduces jamming caused by friction. The eccentric arrangement of the one-piece transmission and drive components makes power transmission more direct, reducing energy loss from multiple linkages and providing a more effective deep muscle massage effect. The simplified transmission structure reduces wear between moving parts and losses from long-term use, thereby extending the massager's lifespan.

[0039] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] Please see Figures 1-5 An embodiment of this application provides a leg massager 100, including a base 30, a housing 10, and a massage component 20;

[0041] The housing 10 is disposed on the base 30 and has an inner cavity 11 and a through hole 12 opened on the side wall of the housing 10 and communicating with the inner cavity 11;

[0042] The massage assembly 20 includes a drive member 21, a transmission member 22, and a massage member 23. The drive member 21 is disposed in the inner cavity 11, the transmission member 22 is disposed on the drive shaft of the drive member 21, and the massage member 23 is disposed on the transmission member 22 and protrudes out of the through hole 12.

[0043] The transmission component 22 is an integral structure and is eccentrically arranged with the driving component 21. It is used to push the massage component 23 out through the through hole 12 or retract it into the inner cavity 11 when the driving component 21 is running.

[0044] Specifically, the base 30 provides a stable support structure for the entire massager and supports the massager's housing 10 and internal components. A through hole 12 on the side wall of the housing 10 serves as a movement channel for the massage element 23, allowing it to freely extend and retract between the inside and outside of the housing 10. A soft leather sleeve (not shown) is provided on the outside of the housing 10 to improve sealing, reduce the entry of debris into the inner cavity 11, and enhance durability. The massage element 23 extends outside the leather sleeve, and a transmission component 22 connects the drive component 21 and the massage element 23, converting the power of the drive component 21 into the reciprocating motion of the massage element 23.

[0045] Furthermore, the integrated structure reduces component splicing, improves structural stability, and maintains stability under long-term high-frequency motion, providing a more stable and powerful massage effect. The eccentric setting causes the transmission component 22 to rotate around a non-central axis, causing the massage component 23 to produce alternating pushing and retracting movements. When retracting, the end of the massage component 23 abuts against the leather sleeve.

[0046] Furthermore, the massager's housing 10 and internal components are located at the center of the base 30. Arc-shaped grooves are provided on both sides of the housing 10 for placing the legs. The massage component 20 is positioned at the center and extends and retracts, while the massage head reciprocates to effectively massage the legs. An eccentric design ensures that the massage component 23 performs periodic pushing motion during operation.

[0047] When the drive unit 21 starts operating, its drive shaft drives the transmission unit 22 to rotate. Because the transmission unit 22 is eccentrically positioned, its movement causes the massage unit 23 to perform a pushing motion along a specific trajectory. When the eccentric portion 222 of the transmission unit 22 moves outward, the massage unit 23 protrudes through the through hole 12, massaging the legs. When the eccentric portion 222 of the transmission unit 22 moves inward, the massage unit 23 retracts into the inner cavity 11, completing one massage cycle. As the drive unit 21 continues to operate, the massage unit 23 continuously performs the pushing / retracting motion, creating a rhythmic pushing and massaging effect on the legs.

[0048] In summary, the integrated transmission component 22 avoids wear, loosening, or jamming caused by multiple moving joints. Because energy transmission is more direct, the massage component 23 can more effectively target leg muscles, making it suitable for deep massage needs.

[0049] In one specific embodiment, the transmission member 22 includes a transmission part 221 and a plurality of eccentric parts 222. The transmission part 221 is disposed on the drive shaft of the drive member 21 and is coaxially disposed with the drive shaft. The massage member 23 is disposed on the eccentric parts 222, and the transmission part 221 is spaced apart from each of the eccentric parts 222.

[0050] Specifically, the transmission unit 221, as the core part of the transmission component 22, is fixedly connected to the drive shaft of the drive component 21 to realize power transmission. By being coaxially arranged, the rotational stability of the transmission unit 221 is ensured, and the multiple eccentric parts 222 can be simultaneously subjected to force to achieve the preset motion mode.

[0051] Furthermore, the eccentric part 222 and the transmission part 221 are arranged in a Z-shape. The rotation of the ejector part drives the massage member 23 to move in an arc-shaped trajectory, enabling the massage member 23 to perform dynamic actions such as pushing and pulling. The spaced ejector parts allow the massage member 23 to massage different points, achieving a more comprehensive massage effect.

[0052] In one specific embodiment, the housing 10 further includes a fixing part 13, which extends inward from the housing 10. The transmission part 221 is disposed on the fixing part 13, and two adjacent eccentric parts 222 protrude in opposite directions, so that when the driving member 21 moves, two adjacent massage members 23 are alternately pushed out or retracted into the inner cavity 11 through the through hole 12.

[0053] Specifically, the fixing part 13 is integrated with the housing 10, which can enhance the strength of the internal structure. Because the transmission parts 221 are spaced apart, the fixing part 13 fixes multiple transmission parts 221 respectively, providing installation positions for the transmission parts 221 so that they can operate stably, reducing the shaking or offset of the transmission parts 22 when moving at high speed, and improving the overall stability.

[0054] Furthermore, the opposite protrusion arrangement of adjacent eccentric portions 222 means that when one eccentric portion 222 extends the massage element 23 outward, the massage element 23 of the other eccentric portion 222 is in a retracted state. This arrangement ensures that the two massage elements 23 do not move simultaneously, but rather extend alternately from the through hole 12 of the housing 10. Compared to traditional single-point or simultaneous extension and retraction massage modes, the staggered movement allows different areas to be massaged alternately, enhancing the overall rhythm and layering.

[0055] Furthermore, the pushing and pressing movements of the massage components 23 are performed alternately, more closely resembling the kneading motion of a human hand massage, thus enhancing the massage experience. Since the adjacent eccentric parts 222 move in opposite directions, they create a certain degree of balance, reducing overall swaying and improving the stability of the equipment's operation.

[0056] In one specific embodiment, the massage member 23 includes an integrally formed first ejector portion 231, a second ejector portion 232, and an annular portion 233, and the eccentric portion 222 passes through the axis of the annular portion 233;

[0057] The first ejector portion 231 and the second ejector portion 232 are disposed opposite to each other at both ends of the annular portion 233, and are used to eject or retract into the inner cavity 11 through the through hole 12 in an alternating manner when the driving member 21 is driven.

[0058] Specifically, the first ejector portion 231 and the second ejector portion 232 are respectively located at both ends of the annular portion 233, forming a complete component. Under the action of the driving member 21, the entire massage component 23 will move accordingly. The first ejector portion 231 and the second ejector portion 232 can move alternately through the through hole 12. Both legs can be massaged simultaneously to achieve a uniform massage effect. When the eccentric portion 222 passes through the axis of the annular portion 233, the entire massage component 23 can move synchronously with the arc trajectory of the eccentric portion 222, and the driving force is evenly distributed to the entire massage component 23, preventing swaying or shaking caused by uneven force.

[0059] Furthermore, the symmetrical arrangement of the two ejector parts allows them to move alternately in opposite directions. This alternating ejection process prevents lateral deviation or imbalance. The alternating ejection of two adjacent massage pieces 23, combined with the alternating ejection of the two ejector parts, enhances the three-dimensionality of the movement. By combining these two alternating methods, the movement is not limited to a single point of extension and contraction, but rather forms a wide-ranging, layered undulating sensation. The double alternating ejection can reach deeper contact areas, making the massage effect more thorough and even.

[0060] In one specific embodiment, the massage component 20 further includes a flexible member 24, which is sleeved on the eccentric portion 222 and conforms to the inner surface of the annular portion 233;

[0061] The massage member 23 also includes a limiting part 237, which is arranged around the inner surface of the annular part 233. One side of the flexible member 24 abuts against the limiting part 237 to limit the displacement of the flexible member 24.

[0062] Specifically, the flexible component 24, fitted onto the eccentric portion 222, reduces the impact force when the eccentric portion 222 directly drives the massage component 23, resulting in smoother movement. The flexible component 24 acts as a buffer, reducing the direct impact between the eccentric portion 222 and the annular portion 233, thereby reducing noise generation during use. The flexibility of the flexible component 24 can also absorb some vibration energy, preventing noise from being amplified through structural resonance, resulting in smoother and quieter operation. Furthermore, the limiting portion 237 restricts the movement of the flexible component 24, allowing for better assembly of the flexible component 24 during assembly and enhancing its fixation effect, preventing loosening or slippage due to prolonged use.

[0063] Furthermore, the flexible component 24 is made of silicone, rubber, or a polymer elastic material, possessing a certain degree of elasticity and cushioning. The flexible component 24 conforms to the inner surface of the eccentric portion 222, preventing significant displacement. The limiting portion 237 is annularly disposed on the inner surface of the annular portion 233, fixing the position of the flexible component 24. It also serves to stabilize the flexible component 24 during assembly.

[0064] In one specific embodiment, the massage member 23 further includes a massage portion 234, which is respectively disposed at the end of the first ejector portion 231 and the second ejector portion 232 away from the annular portion 233, and the massage end of the massage portion 234 has an arc-shaped surface.

[0065] Specifically, the massage section 234 is located at the distal end of the first ejector section 231 and the second ejector section 232, that is, they are at the foremost end of the massage element 23 and directly contact the user's skin. The massage end is designed with a curved surface, which can gently conform to the skin during the operation of the device, avoiding excessive pressure that could cause discomfort during the massage.

[0066] In one specific embodiment, the direction in which the massage portion 234 faces the annular portion 233 is defined as the first direction, the projected area of ​​the massage portion 234 along the first direction is a, the projected area of ​​the first ejector portion 231 and the second ejector portion 232 along the first direction is b, and a≥b.

[0067] Specifically, the projected area of ​​the massage part 234 along the first direction is greater than or equal to the projected area of ​​the protruding part. The larger contact area of ​​the massage part 234 allows for wider coverage during movement. This larger contact area disperses pressure, providing a more even pressure distribution. It also avoids discomfort or pain caused by excessively small massage points, improving user comfort.

[0068] Furthermore, a larger 'a' ensures that the massage part 234 does not solely bear the massage pressure from its protruding portion, but rather distributes the pressure, avoiding discomfort caused by excessively concentrated massage. If 'a' is much larger than 'b', the massage part 234 can provide a smoother transition during movement, reducing stinging sensations and improving the user experience. The overall coverage area of ​​the massage part 234 is relatively large, allowing for better envelopment of the massage area, improving the fit of the massage, and making the massage feel softer and more natural.

[0069] In one specific embodiment, the massage member 23 further includes a first adhesive layer 235 and a second adhesive layer 236, wherein the first adhesive layer 235 is disposed between the flexible member 24 and the eccentric portion 222, and the second adhesive layer 236 is disposed between the flexible member 24 and the annular portion 233.

[0070] Specifically, an adhesive layer is added to massage component 23 to bond different parts together, improving the stability and durability of the overall structure. This reduces the risk of separation or loosening due to prolonged use, thus enhancing durability. The adhesive layer also provides additional cushioning, making the massage component 234 move more smoothly during movement and improving comfort.

[0071] In one specific embodiment, the housing 10 further includes a partition plate 14, which divides the inner cavity 11 into a first cavity 111 and a second cavity 112. The driving member 21 is disposed in the first cavity 111, and the driving shaft of the driving member 21 extends into the second cavity 112.

[0072] The massage component 20 also includes a connector 25, one end of which is sleeved on the drive shaft of the drive component 21, and the other end of which is sleeved on the transmission component 22.

[0073] Specifically, the partition plate 14 divides the internal space into two independent cavities, effectively separating different components. The drive component 21 and the transmission component 22 are housed separately in the two cavities, reducing unnecessary mutual interference. The separate placement in the two cavities makes the internal space more organized, the device design more compact, and improves stability during use. The division into two cavities allows for modularization of the vibrator's internal components, enabling better assembly or disassembly of parts within each cavity during assembly or disassembly.

[0074] Furthermore, connector 25 effectively connects drive component 21 and transmission component 22, ensuring that power is transmitted from drive component 21 to transmission component 22 via drive shaft, and then drives massage component 23 or other functional components via transmission component 22. This allows each functional component to be designed separately, yet they can all function as a whole through connector 25. The use of connector 25 ensures a tight fit between drive component 21 and transmission component 22, guaranteeing the accuracy and stability of power transmission. Since drive component 21 and transmission component 22 are fixed and connected through connector 25, disassembly, maintenance, or replacement of individual components can be easily accomplished by detaching connector 25 without disassembling the entire system.

[0075] In one specific embodiment, the fixing part 13 has a wire groove 131, which is arranged parallel to the transmission part 221 and is used to fix the wire to prevent it from affecting the rotation of the transmission part 221.

[0076] Specifically, the fixing part 13 provides stable support and ensures the correct positioning of each component. The cable tray 131 has a specially designed slot or groove on the fixing part 13, the function of which is to facilitate wiring, allowing wires to pass through neatly without obstructing the normal operation of other components. The cable tray 131 is arranged parallel to the transmission part 221, meaning that the routing of the wires inside the equipment will not cross the transmission part 221, ensuring that the movement of the transmission part 221 is not interfered with by the cables.

[0077] Furthermore, the wires are fixed along the cable tray 131, preventing them from touching the transmission part 221 during equipment operation and thus preventing equipment malfunctions due to entanglement or jamming. The parallel arrangement optimizes the internal structure of the equipment, making the overall layout more compact and improving space utilization.

[0078] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
