Abstract
Description
[Technical Field]
[0001] This utility model relates to the technical field of massagers, and more particularly to a rotary massager equipped with a rotation mechanism. [Background technology]
[0002] Massagers are devices that use physical principles such as mechanical vibration, kneading, tapping, heat, electromagnetic induction, and air pressure, or a combination of these with meridian theory in traditional Chinese medicine, to stimulate muscles, fascia, meridians, acupoints, and other areas to achieve health maintenance, physical therapy, or rehabilitation effects, such as relieving muscle tension and fatigue, promoting local blood circulation, alleviating pain and discomfort, regulating nervous function, and promoting mental and physical relaxation, and they come in a wide variety of forms. Known massagers include handheld, portable, wearable (e.g., neck massagers and lumbar massage belts), stationary (e.g., massage chairs), and foot bath-type massagers, with rotary massagers being an important category among them. However, in conventional rotary massagers, the surface shape of the massage head is limited to a single shape, such as spherical or cylindrical, and the mechanical stimulation pattern during rotation is also fixed, which limits the stimulation range and makes the stimulation effect on deep muscle tissue insufficient, resulting in a narrow massage application range and insufficient relief of user fatigue. Summary of the Invention
[0003] This utility model was invented to solve the problems of the prior art described above, and aims to provide a rotary massager that can solve the problems of narrowing the massage range and making it difficult for the user to relieve fatigue, which are caused by the massage head having a single surface shape and the mechanical stimulation pattern being fixed during rotation.
[0004] To achieve this objective, the present utility model employs the following technical configuration: The rotary massager of the present utility model has a drive motor fixed to the lower end of the interior of a housing, and a first transmission mechanism connected to the output end of the drive motor. The first transmission mechanism is connected to a second transmission mechanism, and the second transmission mechanism is connected to massage rods. The housing is connected to a connecting plate, and at least one massage rod is provided on the connecting plate, and the number and arrangement of the massage rods are replaceable or adjustable. With this technical configuration, when the drive motor is activated, the first gear mechanism rotates, thereby driving the face gear to rotate. The face gear then rotates the rotary gear, which then drives the positioning pin to rotate. The rotary gear then drives the gear mechanism, causing the holed gear to rotate. The holed gear then rotates the engaging part, which then rotates the massage rod. The massage rod has an asymmetric curved surface that presses against specific areas of the user during rotation, expanding the massage area, optimizing the user experience, and alleviating fatigue.
[0005] Preferably, an installation plate is fixed to the lower end inside the housing, a drive motor is arranged on the upper part of the installation plate, the drive motor is fixedly connected to a first gear mechanism, a second gear mechanism is arranged outside the first gear mechanism, massage rods are attached to the second gear mechanism, the drive motor generates rotational power, and the power is transmitted to the massage rods via the first gear mechanism and the second gear mechanism in sequence, causing at least one massage rod to rotate. Preferably, the gear mechanism includes a gear ring, the inside of which is fixed to the outer periphery of the positioning pin, and a sun gear is attached to the inside of the gear ring. Preferably, the drive unit includes a fixed block, the bottom of which is mounted inside the housing, a drive motor fixed to the side of the fixed block, the output end of which is connected to a first transmission gear, the first transmission gear meshing with a second transmission gear, and a rotating shaft fixedly connected inside the second transmission gear. Preferably, two drive motors are provided and are arranged symmetrically on both sides of the second transmission gear, and two first transmission gears are provided and are similarly arranged symmetrically on both sides of the second transmission gear. Preferably, the rotary shaft is fixedly connected to a first gear mechanism, and the teeth of the first gear mechanism mesh with the teeth of a face gear. Preferably, the outer periphery of the rotary shaft is rotatably attached inside the housing, and the lower end of the rotary shaft is connected to the upper part of the first gear mechanism. Preferably, the inner periphery of the sun gear meshes with the outer periphery of the rotary gear, and the upper end of the sun gear is rotatably attached to the lower end of a mounting plate. Preferably, the outer periphery of the hole gear is in mesh with the teeth of a gear ring, and the gear ring is rotatably attached to the outer periphery of a positioning pin at its inner periphery.
[0006] Operating principle: When the drive motor is started, the rotating shaft rotates, which in turn rotates the first gear mechanism. This drives the face gear, which rotates the rotating gear together with the face gear, which in turn drives the sun gear to rotate. The gear ring rotates on its axis due to the sun gear, which rotates the hole gear, which rotates the mating part, which in turn rotates the massage rod. The surface of the massage rod has an asymmetric curved structure, which massages specific parts of the user as it rotates, expanding the massage area, improving the user's experience and reducing fatigue. By attaching a first transmission gear to both sides of the second transmission gear and adjusting the rotational direction and speed of the left and right drive motors, the rotational speed and direction of the second transmission gear can be controlled. While inertia makes it difficult to stop the massage rod suddenly when controlled by a single drive motor, the configuration with two drive motors makes it possible to stop the second transmission gear suddenly. Furthermore, even if one motor malfunctions, the other motor can maintain the device's basic operation. This configuration improves the accuracy and safety of massage rod operation control, reduces the risk of the device losing functionality, and enhances long-term reliability and fault tolerance. The connecting plate is detachable with bolts, allowing the massage rods inside to be easily attached or detached. Furthermore, the connecting plate has mounting holes in multiple locations, allowing the attachment position and number of massage rods to be adjusted according to the user's physical characteristics, treatment area, and desired pressure level. This allows the device to meet various user needs, improves adaptability and efficiency in use, and avoids discomfort caused by oversized massage rods.
[0007] The present invention provides a rotary massager, which has the following beneficial effects: 1. In this utility model, the driving motor is started to rotate the rotary shaft, which then rotates the first gear mechanism, which drives the face gear, which rotates the rotary gear together with the face gear, and then the sun gear is driven by the rotary gear to rotate, thereby expanding the massage area, improving the user's experience and reducing fatigue. 2. This utility model arranges the first transmission gear symmetrically on both sides of the second transmission gear, allowing the rotation speed and direction of each drive motor to be adjusted independently, thereby enabling precise control of the rotation speed and direction of the second transmission gear, improving the accuracy and safety of the massage rod operation control, reducing the risk of the entire device losing function, and increasing long-term reliability and fault tolerance. 3. This utility model allows the connecting plate to be attached or detached with bolts, allowing the massage rods inside to be attached or detached. Furthermore, the connecting plate has mounting holes in multiple different positions, allowing the attachment positions and number of massage rods to be adjusted. This meets the diverse needs of users, improves the adaptability and efficiency of the device to the usage environment, and avoids discomfort caused by oversized massage rods.

DETAILED DESCRIPTION OF THE INVENTION
[0009] The technical solutions of the present invention will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments that can be obtained by those skilled in the art without creative ingenuity fall within the scope of protection of the present invention.
[0010] 1 to 5, in a rotary massager according to one embodiment of the present invention, a drive motor 18 is fixed to the lower end inside a housing 1, and a first transmission mechanism 22 is connected to the output end of the drive motor 18. The first transmission mechanism 22 is connected to a second transmission mechanism 23, which is further connected to massage rods 13. The housing 1 is connected to a connecting plate 12, and at least one massage rod 13 is provided on the connecting plate 12, and the number and arrangement positions of the massage rods 13 are replaceable or adjustable. Specifically, when the drive motor 18 is activated, the first transmission mechanism 22 rotates, which then drives the second transmission mechanism 23, and finally the massage rod 13 rotates on its axis via the second transmission mechanism 23. The detailed transmission paths within the first transmission mechanism 22 and the second transmission mechanism 23 are as follows: The drive motor 18 rotates the first gear mechanism 5, which in turn rotates the face gear 6 synchronously. The housing 1 seals the internal structure of the device to ensure waterproofing. The face gear 6 is fixedly connected to the rotary gear 8, and the rotation of the face gear 6 rotates the rotary gear 8 synchronously. The rotary gear 8 is also fixedly connected to the positioning pin 11, and the positioning pin 11 also rotates synchronously. Furthermore, the gear mechanism 20 rotates via the rotary gear 8, and at this time, the rotation of the gear mechanism 20 rotates the holed gear 7 within the space formed between the installation plate 2 and the connecting plate 12. The holed gear 7 is connected to a fitting 14, and as the holed gear 7 rotates, the fitting 14 also rotates, which in turn rotates the massage rod 13 fixed to the fitting 14. The outer surface of the massage rod 13 has a curved shape with irregular concaves and convexes, and by applying massage stimulation to specific parts of the user while rotating, it is possible to expand the massage range, improve comfort, and relieve fatigue.
[0011] As shown in Fig. 3, an installation plate 2 is fixed to the lower end inside the housing 1, and a drive motor 3 is disposed above the installation plate 2. The drive motor 3 is fixedly connected to a first gear mechanism 5, and a second gear mechanism 21 is disposed outside the first gear mechanism 5, and massage rods 20 are attached to the second gear mechanism 21. The drive motor 3 generates rotational power, which is transmitted to the massage rods 20 via the first gear mechanism 5 and the second gear mechanism 21 in this order, causing at least one massage rod 20 to rotate. Specifically, when the drive motor 3 is started to rotate the first gear mechanism 5, the second gear mechanism 21 rotates, and finally the massage rod 20 is rotated by the second gear mechanism 21. The detailed transmission paths inside the first transmission mechanism 22 and the second transmission mechanism 23 are as follows. The power of the drive motor 3 rotates the first transmission gear 16, which rotates the second transmission gear 17, and since the second transmission gear 17 is fixedly connected to the rotary shaft 19, the rotary shaft 19 rotates inside the housing 1. The sun gear 9 rotates when the rotary gear 8 is driven, and the sun gear 9 is fixedly connected to the gear ring 10, so the gear ring 10 rotates when the sun gear 9 rotates.
[0012] 5 and 6, gear mechanism 20 includes gear ring 10, the interior of which is fixed to the outer periphery of positioning pin 11. Sun gear 9 is attached to the interior of gear ring 10, and when sun gear 9 is rotated by rotating gear 8, gear ring 10 also rotates in conjunction with it. 4, the drive unit includes a drive motor 18, and the output end of the drive motor 18 is connected to a first transmission gear 16. The first transmission gear 16 is in mesh with a second transmission gear 17, and a rotating shaft 19 is fixedly connected to the inside of the second transmission gear 17. Specifically, when the drive motor 18 is started, the first transmission gear 16 rotates, which causes the second transmission gear 17 to rotate on its axis, and further causes the rotating shaft 19 integrated with the second transmission gear 17 to rotate inside the housing 1. As shown in Fig. 4, two drive motors 18 are provided, and are arranged symmetrically on both sides of the second transmission gear 17. Two first transmission gears 16 are also provided, and are similarly arranged symmetrically on both sides of the second transmission gear 17. Specifically, the first transmission gear 16 is attached to both sides of the second transmission gear 17, and the rotational speed and direction of the second transmission gear 17 can be controlled by adjusting the rotational direction and speed of the left and right drive motors 18. Control using a single drive motor 18 makes it difficult to suddenly stop the massage rod 13 due to inertia. However, with the configuration using two drive motors 18, reversing the rotational direction of the first transmission gear 16 locks the second transmission gear 17, making it possible to suddenly stop the massage rod 13. Furthermore, even if a malfunction occurs in one motor 18, the other motor 18 can continue to operate the device. This configuration improves the accuracy and safety of the massage rod 13's operation control, prevents complete shutdowns due to malfunctions, and enhances long-term reliability and fault tolerance.
[0013] As shown in FIG. 3, the rotary shaft 4 is fixedly connected to a first gear mechanism 5, and the teeth of the first gear mechanism 5 are in mesh with the teeth of a face gear 6. Specifically, the rotary shaft 4 drives and rotates the first gear mechanism 5, which in turn rotates the face gear 6. As shown in FIG. 4, the outer periphery of the rotating shaft 19 is rotatably attached inside the housing 1, and the lower end of the rotating shaft 19 is connected to the upper part of the first gear mechanism 5. Specifically, the rotary shaft 19 drives the first gear mechanism 5 to rotate, and the housing 1 fixes the mounting position of the rotary shaft 19 to prevent deviation during rotation. As shown in FIG. 5, the inner periphery of the sun gear 9 meshes with the outer periphery of the rotary gear 8 , and the upper end of the sun gear 9 is rotatably attached to the lower end of the installation plate 2 . Specifically, the rotary gear 8 drives the sun gear 9 to rotate, and the installation plate 2 stabilizes the mounting position of the sun gear 9 and prevents deviation during rotation. As shown in FIG. 5, the outer periphery of the holed gear 7 is engaged with the teeth of a gear ring 10, and the inner periphery is attached to the outer periphery of a positioning pin 11 so that the gear ring 10 can rotate. Specifically, the gear ring 10 drives the hole gear 7 to rotate, and the positioning pin 11 stabilizes the mounting position of the gear ring 10 and prevents deviation during rotation.
[0014] As shown in Figures 7 to 11, this utility model can accommodate a drive mode using two drive motors 3 as well as a drive mode using a single drive motor 3. The drive motor 3 is fixedly connected to a first gear mechanism 5, which comes in two forms. One is composed of a horizontal gear and a vertical gear, and the vertical gear meshes with a face gear 6 to transmit the power of the rotating shaft 4. The other is a vertical face gear that meshes with the face gear 6 via vertical teeth to transmit power. The face gear 6 is fixed inside the installation plate 2 and is disk-shaped, with teeth on its upper edge. The rotating gear 8 is fixedly connected to the lower part of the face gear 6. The rotating gear 8 is a circular gear that rotates synchronously with the face gear 6. A positioning pin 11 is located below the rotating gear 8 when stationary. It has a cylindrical shape and connects a gear ring 10 to a connecting plate 12. A gear mechanism 20 is fixed to the outer periphery of the positioning pin 11, and the gear mechanism 20 includes a gear ring 10. The gear ring 10 is annular, rotates when driven by the sun gear 9, and transmits torque to the multiple holed gears 7. The inside of the gear ring 10 is fixed to the outer periphery of the positioning pin 11, and the sun gear 9 is also fixed inside the gear ring 10. The sun gear 9 is circular gear-shaped, and its inside meshes with the outside of the rotary gear 8, so it rotates when the rotary gear 8 rotates, and its upper end is rotatably attached to the lower end of the installation plate 2. The following examples are provided in relation to the foregoing.
[0015] Example 1: When the drive motor 3 is started and the rotary shaft 4 is rotated, the rotary shaft 4 drives the first gear mechanism 5, which in turn rotates the face gear 6, which in turn rotates the rotary gear 8 in synchronous rotation. Next, the positioning pin 11 is rotated by the rotary gear 8, which in turn rotates the sun gear 9 on its own axis, which in turn drives the gear ring 10 to rotate. This rotation is transmitted to the holed gear 7, which rotates the fitting portion 14, which in turn rotates the massage rod 13. The massage rod 13 has a curved shape with concave and convex portions, and massages specific parts of the user. Example 2: The drive motor 3 in the first embodiment is replaced with a drive motor 18, and the drive motor 18 is started to drive the first transmission gear 16, which then rotates the second transmission gear 17. After that, the second transmission gear 17 is driven to rotate the rotary shaft 19 inside the housing 1, which then rotates the first gear mechanism 5. By adjusting the mounting position of the drive motor, it is possible to select a mounting method that suits the model of the massage device.
[0016] While embodiments of the present invention have been shown and described, those skilled in the art will recognize that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is intended to be defined by the appended claims and their equivalents.
