Description

Technical Field

[0001] This utility model relates to the field of massage equipment, specifically to a rotary oscillating massage device. Background Technology

[0002] A massager is a device used to soothe muscles, relieve fatigue, promote blood circulation, and relax the mind and body. It provides users with an effect similar to a human massage by simulating massage techniques.

[0003] The present invention CN202420958997.0 discloses a planar clamping massage mechanism, which includes a motor disposed in a housing; each end of the output worm gear of the motor is rotatably connected to a massage component; the massage component includes an eccentric wheel, a massage arm sleeved on the eccentric wheel, and a massage head assembly disposed above the eccentric wheel; the massage arm is provided with a sliding groove for limiting movement, and the housing is provided with a limiting post for cooperating with the sliding groove, so that the massage arm performs a reciprocating and oscillating compound motion in a plane under the drive of the eccentric wheel.

[0004] However, with increased usage, the contact surfaces of the slide and the limiting post will wear down, leading to inaccurate fit and affecting the stability and function of the massager. Additionally, the friction between the slide and the limiting post generates noise, which becomes more noticeable after prolonged use and wear, negatively impacting the user experience. Utility Model Content

[0005] The purpose of this invention is to address the problem that the combination of the slide and the limiting post in the existing technology is prone to wear after long-term use, and to provide a rotary oscillating massage device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rotary oscillating massage device, comprising a housing, a drive device capable of outputting rotational power, and at least one pair of massage components. The drive device is located inside the housing, and the output end of the drive device is connected to the massage components. The massage components include an eccentric wheel and a massage arm sleeved on the eccentric wheel. Guide posts for limiting the position are provided on both sides of the massage arm, and guide blocks for cooperating with the guide posts are hinged on the housing, so that the massage arm performs a reciprocating and oscillating compound motion in a plane under the drive of the eccentric wheel.

[0007] Furthermore, the massage arm includes a collar sleeved on an eccentric wheel; one side of the collar extends outward to form an extension arm; guide posts are provided on both sides of the extension arm; and a first massage head extending upward is provided at the end of the extension arm away from the collar.

[0008] Furthermore, several reinforcing ribs are fixedly provided below the first massage head.

[0009] Furthermore, the guide block is provided with a guide groove adapted to the massage arm, and limiting grooves adapted to the guide block are provided on both sides of the guide groove. The bottom end of the guide groove is provided with a hinge hole for hinged connection with the housing.

[0010] Furthermore, the housing is provided with an inwardly recessed groove for limiting the rotation angle of the guide block, and the groove is provided with a hinge post for hinged to the guide block.

[0011] Furthermore, it also includes a massage head assembly located above the eccentric wheel. The massage head assembly includes a massage seat and a second massage head mounted on one side of the massage seat. The massage seat has a connection hole in the middle that is connected to the output end of the drive device for anti-rotation.

[0012] Furthermore, the second massage head includes a connecting column, a rotating body, and a cap for limiting the rotating body. The connecting column is fixedly connected to the massage seat, and the top of the connecting column is fitted with a cap. The rotating body is located between the cap and the massage seat and is fitted onto the connecting column.

[0013] Furthermore, the side wall of the rotating body is provided with a number of inwardly recessed massage grooves arranged at equal intervals.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0015] The guide block and massage arm have surface contact, which can withstand long-term use without being easily worn. This improves the durability of the entire system, especially under prolonged use or high-intensity exercise, reducing the possibility of damage.

[0016] Traditional massage arms use through slots for positioning, which compromises the arm's integrity and affects its strength and rigidity. However, using guide blocks for positioning completely avoids this impact on the massage arm's structure, thus preserving its strength.

[0017] The function of the eccentric wheel is to create regular changes in the movement trajectory of the massage head through asymmetrical rotation, simulating different massage techniques. Because the massage head assembly is driven by the eccentric wheel, the movement of the massage head can be more flexible and complex, thereby enhancing the massage effect.

[0018] The device drives the massage arm to generate compound motion through an eccentric wheel, which, in conjunction with the rotation of the second massage head, simulates massage movements. Guide blocks ensure that the massage components can move within a reasonable range, thereby providing a more precise and effective massage experience. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] See Figure 1-5 As shown, the technical solution adopted in this specific embodiment is: a rotary oscillating massage device, which includes a housing 1, a drive device 2 capable of outputting rotational power and at least a pair of massage components 3. The drive device 2 is located inside the housing 1, and the output end of the drive device 2 is connected to the massage components 3.

[0030] The specific massage component 3 includes an eccentric wheel 31, a massage arm 32 sleeved on the eccentric wheel 31, and a massage head assembly 4 located above the eccentric wheel 31. The design of the eccentric wheel 31, massage arm 32, and massage head assembly 4 can realize compound movements, making the massage effect more comprehensive and effective, and better simulating the movements of manual massage.

[0031] More specifically, the massage arm 32 has guide posts 33 on both sides for limiting movement, and a guide block 34 is hinged to the housing 1 to cooperate with the guide posts 33, so that the massage arm 32 performs a compound motion of reciprocating and oscillating in a plane under the drive of the eccentric wheel 31. The cooperation between the guide posts 33 and the guide blocks 34 can effectively limit the range of motion of the massage arm 32, avoid excessive deviation, ensure that the massage arm 32 works stably within a specific trajectory, and improve comfort and safety.

[0032] More specifically, the massage arm 32 includes a collar 321 fitted onto the eccentric wheel 31, with one side of the collar 321 extending outward to form an extension arm 322. The design of the collar 321 and extension arm 322 allows the massage head to move periodically with the rotation of the eccentric wheel 31, providing a stable and even massage effect. Guide posts 33 are provided on both sides of the extension arm 322, and a first massage head 323 extending upward is provided at the end of the extension arm 322 away from the collar 321. The upwardly extending first massage head 323 can better contact the massage area, improving the coverage of the massage effect. Several reinforcing ribs 3231 are fixedly provided below the first massage head 323. The design of the reinforcing ribs 3231 effectively enhances the overall structural strength of the part where the first massage head 323 is located, preventing the massage head from deforming or being damaged due to pressure during massage. This allows the massage head to withstand greater force while maintaining long-term stability and durability.

[0033] The guide block 34 is provided with a guide groove 341 that matches the massage arm 32. Limiting grooves 342 that match the guide block 34 are provided on both sides of the guide groove 341. The guide block 34 allows the massage arm 32 to move precisely along a predetermined trajectory during use. The bottom end of the guide groove 341 is provided with a hinge hole 343 for hinged connection with the housing 1. This precise guiding and limiting function not only ensures the stability of the massage component during movement but also improves the accuracy of the massage. The housing 1, which cooperates with the guide block 34, is provided with an inwardly recessed groove 11 to limit the rotation angle of the guide block 34. A hinge post 12 for hinged connection with the guide block 34 is provided within the groove 11.

[0034] The specific massage head assembly 4 includes a massage seat 41 and a second massage head 42 mounted on one side of the massage seat 41. The massage seat 41 has a connection hole 411 in the middle that connects to the output end of the drive device 2 to prevent rotation. The second massage head 42 includes a connecting post 421, a rotating body 422, and a cap 423 for limiting the rotation of the rotating body 422. The connecting post 421 is fixedly connected to the massage seat 41, and the cap 423 is installed at the top of the connecting post 421. The cap 423 prevents the rotating body 422 from detaching from the connecting post 421 due to excessive rotation, thus extending the service life of the massage head assembly 4. The rotating body 422 is fitted between the cap 423 and the massage seat 41, and is fitted onto the connecting post 421. This structure allows the rotating body 422 to rotate without detaching from the connecting post 421 due to excessive rotation. The free rotation of the rotating body 422 improves the massage effect. Furthermore, the rotating body 422 has several inwardly recessed massage grooves 4221 arranged at equal intervals on its side wall. The massage grooves 4221 enhance the pressure distribution and comfort during the massage, allowing the massage head to generate more local pressure when in contact with the skin, thereby improving the targeting and effectiveness of the massage.

[0035] The working principle of this invention is as follows: The drive device 2 generates rotational power and transmits it to the massage arm 32 through the eccentric wheel 31. Driven by the eccentric wheel 31, the massage arm 32 not only performs linear reciprocating motion but also swings at a certain angle around its hinge point. The cooperation between the guide post 33 and the guide block 34 ensures the precise trajectory of the massage arm 32 and effectively controls its range of motion.

[0036] At the same time, the massage head assembly 4 will also rotate according to the power of the drive device 2. Since the middle part of the massage seat 41 is directly connected to the output end of the drive device 2, the massage seat 41 rotates around the output end of the drive device 2, thereby providing a different massage effect than the massage arm 32.

[0037] The entire device is driven by the rotational power of the drive unit 2, which propels the coordinated movement of multiple components, including the combined movement of the massage arm 32 and the rotational movement of the massage head assembly 4. Through massage movements in different directions and methods, it achieves effective massage and relaxation of specific parts of the body.

[0038] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
