Description

Technical area

[0001] The utility model relates to the technical field of the massage device, specifically to a rotary massage device. Background technology

[0002] A massager is a type of physical principle that uses mechanical vibration, kneading, hammering, hot compress, electromagnetic induction, air pressure extrusion, etc., or combines it with the theory of meridians in traditional Chinese medicine to stimulate human muscles, fascia, meridians, acupuncture points, and other body parts to relieve muscle tension and fatigue, improve local blood circulation, relieve pain and discomfort, regulate nerve function, promote physical and mental relaxation, and achieve other health, physical therapy, or rehabilitation effects. Products are rich and diverse, including handheld, portable, wearable (e.g., neck massager, waist massage belt), desktop (e.g., massage chair), foot massage, and other types. Among them, the rotary massager is an important massager.

[0003] The massage head of the existing rotary massager has a single surface geometry (e.g., spherical / cylindrical), and the mechanical stimulation pattern during rotation is fixed and has a narrow range, which reduces the activation effect on the deep muscle tissue, resulting in a narrow massage area and making it difficult to relieve user fatigue. Contents of the utility model

[0004] The utility model addresses the deficiencies of the prior art and proposes a rotary massager. It solves the problem that the surface geometry of the massage head of the existing rotary massager is simple and the mechanical stimulation mode is fixed during rotation, resulting in a narrow massage area and difficulty in relieving user fatigue.

[0005] To achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions: a rotary massager that attaches the inner lower end of the housing to a drive motor. The output end of the drive motor is connected to a transmission component 1. The transmission component 1 is connected to a transmission component 2. The transmission component 2 is connected to a massage rod. The housing is connected to a connecting plate. The connecting plate is provided with at least one massage rod, the number and position of which are interchangeable or adjustable.

[0006] Through the technical solution described above, the drive assembly is activated to rotate the gear assembly 1. The gear assembly 1 drives the upper gear, and the rotating gear rotates with the upper gear. The rotating gear then drives the limit column, and the rotating gear drives the gear assembly. At this time, the gear assembly drives the perforated gear, and the perforated gear drives the limit plate. The limit plate drives the massage stick, whose surface has an asymmetrically curved structure. During the rotation of the massage stick, the user's specific body part is pressed, thereby expanding the massage area, optimizing the user experience, and reducing fatigue.

[0007] Preferably, a control plate is rigidly connected to the lower end of the housing. A drive motor is arranged on top of the control plate. The drive motor is rigidly connected to the gear assembly 1. The gear assembly 2 is arranged outside the gear assembly 1. A massage rod is connected outside the gear assembly 2. The rotational force generated by the drive motor is transmitted to the massage rod via the gear assembly 1 and the gear assembly 2, driving at least one massage rod to rotate.

[0008] Preferably, the gear arrangement comprises a gear ring. The interior of the gear ring is rigidly connected to the exterior of the limiting column. The interior of the gear ring is rigidly connected to a planetary gear.

[0009] Preferably, the drive assembly comprises a fixed block. The bottom of the fixed block is fixedly connected to the housing interior. The side wall of the fixed block is fixedly connected to the drive motor. The output end of the drive motor is connected to the gear 1. The tooth end of the gear 1 meshes with the gear 2. The interior of the gear 2 is fixedly connected to the rotating shaft.

[0010] Preferably, the number of drive motors is two, and they are distributed symmetrically on both sides of the transmission gear 2. The number of transmission gears 1 is two, and these are distributed symmetrically on both sides of the transmission gears 2.

[0011] Preferably, the outer portion of the rotary shaft is fixedly connected to the outer portion of the gear assembly 1. The tooth end of the gear assembly 1 is meshingly connected to the tooth end of the upper gear.

[0012] Preferably, the outer part of the rotary shaft is rotatably connected to the inner part of the housing. The underside of the rotary shaft is connected to the top side of the gear assembly 1.

[0013] Preferably, the inner part of the planetary gear is meshed with the outer part of the rotating wheel. The top of the planetary gear is rotatably connected to the bottom of the adjusting plate.

[0014] Preferably, the outer portion of the perforated gear is meshed with the toothed end of the gear ring. The inner portion of the gear ring is rotatably connected to the outer portion of the limiting column.

[0015] Operating principle: The drive motor is started to drive the rotating shaft. The rotating shaft then drives gear assembly 1, which in turn drives the upper gear. The rotating gear rotates with the upper gear, and then the planetary gear rotates under the drive of the rotating gear. The ring gear rotates, driven by the planetary gear, and this drives the perforated gear. The perforated gear drives the limit plate, which in turn rotates the massage stick. The surface of the massage stick is asymmetrically curved. During rotation, it massages specific parts of the user's body. This expands the massage area, optimizes the user experience, and reduces fatigue.

[0016] The symmetrical arrangement of gear 1 on both sides of gear 2 and the independent adjustment of the speed and rotation direction of the drive motors on both sides allow the speed and rotation direction of gear 2 to be controlled. The dual-motor configuration enables gear 2 to brake quickly. In the single-motor configuration, the braking effect of the massage stick is limited by inertia. If one drive motor fails, the other drive motor can maintain the basic operation of the device while the two drive motors are operating. This improves the control accuracy and operational reliability of the massage stick movement, reduces the risk of functional failure of the entire device, and improves the reliability and fault tolerance of the device during continuous operation.

[0017] The connecting plate can be removed with screws, allowing the massage stick to be mounted or removed. The connecting plate features multiple mounting holes at various positions for attaching the massage sticks. This allows the device to adjust the number of massage sticks and their mounting positions according to the user's physiological characteristics, the massage parts, and the required force. This accommodates the different needs of users, improves the device's application flexibility and efficiency, and avoids discomfort caused by oversized massage sticks.

[0018] The utility model relates to a rotary massager that has the following beneficial effects: 1. The utility model starts the drive motor to drive the rotary shaft. The rotary shaft then drives the gear assembly 1, which in turn drives the upper gear. The rotary gear rotates with the upper gear, and then the planetary gear rotates under the drive of the rotary gear. This expands the massage area, improves comfort, and reduces user fatigue. 2. The utility model arranges the gear 1 symmetrically on both sides of the gear 2, allowing the speed and direction of the drive motors on both sides to be adjusted independently. This improves the control accuracy and operational reliability of the massage rod movement, prevents the device from completely stopping, and improves the reliability and fault tolerance of the device during long-term use. 3. The utility model allows the connecting plate to be disassembled using screws, allowing the massager to be mounted or removed from the connecting plate. The connecting plate features multiple mounting holes at different positions for attaching the massager. This accommodates the different needs of users, improves the flexibility and efficiency of the device, and avoids discomfort caused by oversized massager rods.

[0021] Below, the technical solution of the utility model is described clearly and completely with reference to the drawings. Obviously, the description of the embodiments is part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all further embodiments achieved by persons skilled in the art without their own creative effort fall within the scope of protection of the utility model. 1. See Fig. The embodiment of the utility model comprises a rotary massager that attaches the inner lower end of the housing 1 to a drive motor 18. The output end of the drive motor is connected to a transmission component 122. The transmission component 121 is connected to a transmission component 223. The transmission component 223 is connected to a massage rod 13. The housing 1 is connected to a connecting plate. The connecting plate 12 is provided with at least one massage rod 13, the number and position of which are interchangeable or adjustable.

[0022] Specifically, the drive motor 18 is started to rotate the transmission component 122. Then, the transmission component 122 drives the transmission component 223. Finally, the massage stick 13 rotates under the drive of the transmission component 223. The detailed transmission process of the internal parts of the transmission component 122 and the transmission component 223 is as follows: The drive motor 18 drives the gear assembly 15, and the upper gear 6 rotates synchronously with the drive of the gear assembly 15. The housing 1 serves to internally seal and waterproof the device. Since the upper gear 6 is firmly connected to the rotating gear 8, the latter rotates synchronously under the drive of the upper gear 6. Since the limiting column 11 is firmly connected to the rotating gear 8, it rotates synchronously under the drive of the rotating gear 8. Then, the gear assembly 20 rotates synchronously under the drive of the rotating wheel 8. Since the perforated gear 7 is driven by the gear assembly 20, the plate 2 is located in the cavity between the connecting plate 12 and rotates there. Since the limiting plate 14 is connected to the perforated gear 7, it also rotates under the drive of the perforated gear 7.Since the massage rod 13 is connected to the limiting plate 14, it rotates within the connecting plate 12 under the drive of the limiting plate 14. Since the massage rod 13 has an irregularly curved shape, the massage rod 13 massages the desired body part of the user, thereby expanding the massage area, improving the user's comfort, and relieving the user's fatigue.

[0023] 2. See Fig. . An adjusting plate 2 is fixedly connected to the lower end of the housing 1. A drive motor 3 is arranged on top of the adjusting plate 2. The drive motor 3 is fixedly connected to the gear assembly 15. The gear assembly 221 is arranged outside the gear assembly 15. A massage rod 20 is connected outside the gear assembly 221. The rotational force generated by the drive motor 3 is transmitted via the gear assembly 15 and the gear assembly 221 to the massage rod 20 and drives at least one massage rod 20 to rotate.

[0024] The drive motor 3 is turned on to drive the gear assembly 15. Then, the gear assembly 221 rotates under the drive of the gear assembly 15. Finally, the massage stick 20 rotates under the drive of the gear assembly 221. The detailed transmission process of the internal parts of the gear assemblies 122 and 223 is as follows: The drive motor 3 is started to drive the transmission gear 116. Then, the transmission gear 116 drives the transmission gear 217. Since the transmission gear 217 is fixedly connected to the rotation shaft 19, the rotation shaft 19 rotates in the housing 1 under the drive of the transmission gear 217, and the planetary gear 9 rotates under the drive of the rotation gear 8. Since the planetary gear 9 is fixedly connected to the ring gear 10, the ring gear 10 rotates under the drive of the planetary gear 9.

[0025] See Fig. The gear arrangement 20 includes a gear ring 10. The interior of the gear ring 10 is fixedly connected to the outside of the limiting column 11. The interior of the gear ring 10 is fixedly connected to a planetary gear 9.

[0026] In particular, the planetary gear 9 rotates under the drive of the rotating wheel 8. Since the planetary gear 9 is fixedly connected to the gear ring 10, the gear ring 10 rotates under the drive of the planetary gear 9.

[0027] See Fig. The drive assembly comprises a drive motor 18. The output end of the drive motor 18 is connected to a gear 116. The toothed end of the gear 116 is meshed with a gear 217. The interior of the gear 217 is fixedly connected to a rotating shaft 19.

[0028] The drive motor 18 is started to drive the gear 1 16. This then drives the gear 2 17. Since the gear 2 17 is firmly connected to the rotating shaft 19, the latter rotates in the housing 1 due to the drive of the gear 2 17.

[0029] See Fig. . The number of drive motors 18 is two, and these are distributed symmetrically on both sides of the gear wheel 2 17. The number of gear wheels 1 16 is two, and these are distributed symmetrically on both sides of the gear wheels 2 17.

[0030] Specifically, a gear 16 is mounted on both sides of the gear 217. The speed and rotation direction of the gear 217 are adjusted by adjusting the rotation direction and speed of the drive motors 18 on both sides. This allows the gear 116 to change its rotation direction and lock the gear 217. In an emergency, the gear 217 can be braked. With a single drive motor 18, it is difficult to brake the massage stick 13 in an emergency due to inertia. With two drive motors 18, if one drive motor 18 fails, the other can continue to operate the device. This improves the accuracy and safety of the movement control of the massage stick 13, prevents complete device failure, and improves the reliability and fault tolerance of the device during long-term use.

[0033] See Fig. The outer part of the rotating shaft 19 is rotatably connected to the inner part of the housing 1. The underside of the rotating shaft 19 is connected to the top side of the gear assembly 15.

[0034] Specifically, the rotating shaft 19 is used to drive the gear assembly 15 to rotate, and the housing 1 is used to limit the mounting position of the rotating shaft 19 to prevent the rotating shaft 19 from being displaced during rotation.

[0035] See Fig. The inner part of the planetary gear 9 is meshingly connected to the outer part of the rotating wheel 8. The upper side of the planetary gear 9 is rotatably connected to the underside of the adjusting plate 2.

[0036] Specifically, the rotating gear 8 is used to drive the planetary gear 9 and rotate it, and the adjusting plate 2 is used to limit the installation position of the planetary gear 9 to prevent the planetary gear 9 from being displaced when rotating.

[0037] See Fig. The outer portion of the hole gear 7 is meshed with the toothed end of the gear ring 10. The inner portion of the gear ring 10 is rotatably connected to the outer portion of the limiting column 11.

[0038] Specifically, the ring gear 10 is used to drive the hole gear 7 to rotate, and the limiting column 11 is used to limit the installation position of the ring gear 10 to prevent the ring gear 10 from rotating and deviating.

[0039] See Fig.. The utility model can be operated with both a dual drive motor 3 and a single drive motor 3. The drive motor 3 is fixedly connected to the gear assembly 15. The gear assembly 15 is divided into two parts: one consists of a horizontal gear and a vertical gear.

The gear assembly 20 is fixedly connected to the outside of the limit column 11. The gear assembly 20 includes the ring gear 10, which rotates under the drive of the planetary gear 9 and transmits the rotational force through engagement to the perforated gears 7.
