Description

Technical Field

[0001] This application relates to the field of massage equipment technology, and in particular to a multi-mode massager. Background Technology

[0002] With the increasingly fast pace of modern life, people's work and life pressures are constantly increasing, and problems such as physical fatigue and various muscle aches are becoming more and more common. In order to relieve physical discomfort, massage devices, as a convenient and practical health care device, are gradually gaining popularity among consumers.

[0003] Currently, there is a wide variety of massage devices on the market, including handheld massagers, massage chairs, massage cushions, and other forms. However, these massage devices still have many shortcomings in terms of functionality and user experience.

[0004] Existing massage devices also have limitations in the design of their massage heads. Many massage heads can only rotate in one direction, or even if they have forward and reverse rotation functions, they do not make full use of the forward and reverse rotation to achieve different massage effects. Unidirectional rotating massage heads can only provide a fixed massage trajectory and intensity distribution, making it difficult to simulate diverse massage techniques such as traditional Chinese massage and kneading. They cannot accurately massage the muscle direction and characteristics of different body parts. For example, for the massage of the neck and shoulders, due to the complex distribution and direction of muscles, it is difficult to achieve the ideal massage effect with a single massage head rotation method. Therefore, a multi-mode massage device is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a multi-mode massager to solve the problems mentioned in the background art.

[0006] The multi-mode massager provided in this application adopts the following technical solution:

[0007] A multi-mode massager includes a housing, on the outer wall of which a massage head assembly is mounted. The massage head assembly includes a small massage contact and a large massage contact. The small massage contact is movably connected to the inner wall of the large massage contact via a bearing, and the large massage contact is rotatably connected to the outer wall of the end of the housing.

[0008] The housing contains a transmission mechanism that drives the small massage contact head and the large massage contact head to rotate synchronously relative to each other. The transmission mechanism includes a mounting component fixedly connected inside the housing. A first bevel gear is rotatably connected to one outer wall of the mounting component. A servo motor is fixedly mounted inside the housing via a mounting bracket. The output shaft of the servo motor passes through the mounting component and is fixedly connected to a rotating shaft. A connecting rod is mounted inside the rotating shaft via an elastic reset structure. The end of the connecting rod passes through the rotating shaft and is fixedly connected to the small massage contact head. A second bevel gear is also rotatably connected to one inner wall of the mounting component. The rotating shaft passes through the second bevel gear and is fixedly connected to it.

[0009] The inner wall of the mounting component opposite to the second bevel gear is rotatably connected to a third bevel gear via a bushing. Both the third and second bevel gears mesh with the first bevel gear, and the first bevel gear is located between the third and second bevel gears. The end of the bushing away from the third bevel gear extends out of the outer shell and is fixedly connected to the large massage contact head via a connecting ring.

[0010] Preferably, a reciprocating pressing mechanism is installed between the small massage contact and the large massage contact. The reciprocating pressing mechanism includes multiple pulleys and a boss ring. The multiple pulleys are rotatably connected to the inner wall of the small massage contact in a circumferential array at equal intervals. The boss ring is fixedly connected to the inner wall of the large massage contact. The multiple pulleys abut against the boss ring, and the circumferential edge of the boss ring has a wave-shaped design.

[0011] Preferably, the elastic reset structure includes a groove formed on the inner wall of the rotating shaft, the end of the connecting rod located inside the groove is slidably connected to the rotating shaft via a slider, and a spring is sleeved on the outer wall of the connecting rod located inside the groove, one end of the spring is fixedly connected to the outer wall of the slider, and the other end is fixedly connected to the inner wall of the groove.

[0012] Preferably, the bushing, connecting ring, large massage contact head, and bearing are all movably connected to the connecting rod.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] The two massage heads are driven to rotate synchronously relative to each other through a transmission mechanism. At the same time, one of the massage heads can also produce a reciprocating pressing action under the action of a reciprocating pressing mechanism. This unique design allows the massage head to simulate a variety of massage techniques such as traditional Chinese massage and kneading. For example, when massaging areas with complex muscle distribution and direction, such as the neck and shoulders, the synchronous rotation combined with the reciprocating pressing can flexibly adjust the massage trajectory and intensity distribution according to the direction and characteristics of the muscles, so as to achieve precise massage, effectively relieve muscle fatigue and tension, and achieve the ideal massage effect.

[0021] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0022] This application discloses a multi-mode massager. (Refer to...) Figure 1-5 A multi-mode massager includes a housing 1, a massage head assembly, a transmission mechanism, a reciprocating pressing mechanism, and an elastic reset structure.

[0023] The outer shell 1 is the basic support structure of the entire massager. Its outer wall is used to install the massage head assembly, and the interior provides installation space for components such as the transmission mechanism. The outer shell 1 can be made of high-strength plastic or metal to ensure its structural strength and durability. At the same time, the design should take ergonomics into account to facilitate hand operation by the user.

[0024] The massage head assembly includes a small massage contact 7 and a large massage contact 12. The small massage contact 7 is movably connected to the inner wall of the large massage contact 12 via a bearing 13. The inner ring of the bearing 13 is not fixedly connected to the small massage contact 7, while its outer ring is fixed to the inner wall of the large massage contact 12. This connection method allows the small massage contact 7 to move and rotate flexibly inside the large massage contact 12, transforming the direct friction between the small massage contact 7 and the large massage contact 12 into rolling friction, which facilitates the relative rotation of the small massage contact 7 and the large massage contact 12. The large massage contact 12 is rotatably connected to the outer wall of the end of the housing 1, thereby realizing the connection between the massage head assembly and the housing 1, and the large massage contact 12 can also rotate relative to the housing 1.

[0025] The transmission mechanism is used to drive the small massage contact head 7 and the large massage contact head 12 to rotate synchronously relative to each other. The specific structure is as follows:

[0026] Mounting component 2 is fixedly connected inside the housing 1, providing stable support for other transmission components.

[0027] A first bevel gear 3 is rotatably connected to one side of the outer wall of the mounting component 2. The first bevel gear 3 can rotate freely around its connection point with the mounting component 2.

[0028] The servo motor 4 is fixedly installed inside the housing 1 by a mounting bracket. The servo motor 4 serves as a power source to provide power to the entire transmission mechanism. The output shaft of the servo motor 4 passes through the mounting piece 2 and is fixedly connected to the rotating shaft 5. When the servo motor 4 starts, its output shaft drives the rotating shaft 5 to rotate synchronously.

[0029] Inside the rotating shaft 5, a connecting rod 16 is installed via an elastic reset structure. The end of the connecting rod 16 passes through the rotating shaft 5 and is fixedly connected to the small massage contact 7. A second bevel gear 6 is also rotatably connected to the inner wall of one side of the mounting part 2. The rotating shaft 5 passes through the second bevel gear 6 and is fixedly connected to it. Therefore, when the rotating shaft 5 rotates, it will drive the second bevel gear 6 to rotate together.

[0030] The inner wall of the mounting part 2 opposite to the second bevel gear 6 is rotatably connected to the third bevel gear 10 through the bushing 11. The third bevel gear 10 and the second bevel gear 6 are both meshed with the first bevel gear 3, and the first bevel gear 3 is located between the third bevel gear 10 and the second bevel gear 6. The end of the bushing 11 away from the third bevel gear 10 extends out of the outer shell 1 and is fixedly connected to the large massage contact head 12 through the connecting ring 15.

[0031] A reciprocating pressing mechanism is installed between the small massage contact 7 and the large massage contact 12. This mechanism includes multiple pulleys 8 and a boss ring 14. The multiple pulleys 8 are rotatably connected to the inner wall of the small massage contact 7 in a circumferential array at equal intervals. The boss ring 14 is fixedly connected to the inner wall of the large massage contact 12. The multiple pulleys 8 abut against the boss ring 14, and the circumferential edge of the boss ring 14 has a wave-shaped design.

[0032] The elastic reset structure includes a groove 17 formed on the inner wall of the rotating shaft 5. The end of the connecting rod 16 located inside the groove 17 is slidably connected to the rotating shaft 5 via a slider 18. A key block is provided on the slider 18, and a matching keyway is formed on the inner wall of the groove 17. This key connection method ensures that the slider 18 can only move linearly inside the groove 17 and cannot rotate, thereby ensuring that the rotating shaft 5 can drive the connecting rod 16 to rotate. A spring 9 is sleeved on the outer wall of the connecting rod 16 located inside the groove 17. One end of the spring 9 is fixedly connected to the outer wall of the slider 18, and the other end is fixedly connected to the inner wall of the groove 17.

[0033] The bushing 11, connecting ring 15, large massage contact head 12 and bearing 13 are all movably connected to the connecting rod 16. This movable connection method allows the components to move relative to each other and work together, ensuring the normal operation of the massager as a whole.

[0034] The implementation principle of a multi-mode massager according to an embodiment of this application is as follows: When the servo motor 4 is started, the output shaft of the servo motor 4 drives the rotating shaft 5 to rotate. Since the rotating shaft 5 is fixedly connected to the second bevel gear 6, the second bevel gear 6 will rotate together with the rotating shaft 5. The second bevel gear 6 meshes with the first bevel gear 3, thereby driving the first bevel gear 3 to rotate. The first bevel gear 3 meshes with the third bevel gear 10, thereby driving the third bevel gear 10 to rotate. The third bevel gear 10 drives the large massage contact head 12 to rotate through the bushing 11 and the connecting ring 15.

[0035] Meanwhile, the connecting rod 16 inside the rotating shaft 5 is connected to the rotating shaft 5 through an elastic reset structure, and the connecting rod 16 is fixedly connected to the small massage contact 7. Therefore, when the rotating shaft 5 rotates, it will drive the small massage contact 7 to rotate through the connecting rod 16. This achieves the relative synchronous rotation of the small massage contact 7 and the large massage contact 12, providing a basic rotation mode for massage.

[0036] During the synchronous rotation of the small massage contact 7 and the large massage contact 12, the pulley 8 on the inner wall of the small massage contact 7 rolls on the wavy edge of the boss ring 14 on the inner wall of the large massage contact 12. Since the circumferential edge of the boss ring 14 is wavy, the pulley 8 will cause the small massage contact 7 to reciprocate along its radial direction during the rolling process, thereby realizing the reciprocating pressing action on the massage area, increasing the diversity and effect of the massage.

[0037] When the small massage contact 7 performs a reciprocating pressing action, it will generate a certain displacement. At this time, the slider 18 at the end of the connecting rod 16 slides in the groove 17 on the inner wall of the rotating shaft 5. When the small massage contact 7 is subjected to pressure and moves away from the large massage contact 12, the connecting rod 16 drives the slider 18 to slide in the groove 17 and compress the spring 9. When the pressure decreases, the elastic force of the spring 9 will push the slider 18 to slide in the opposite direction in the groove 17, so that the connecting rod 16 and the small massage contact 7 are reset, thereby ensuring that the pulley 8 is always in close contact with the boss ring 14, ensuring the normal operation of the reciprocating pressing mechanism.

[0038] The bushing 11, connecting ring 15, large massage contact head 12, and bearing 13 are movably connected to the connecting rod 16, enabling the components to cooperate with each other during movement. The bushing 11 rotates under the drive of the third bevel gear 10, and drives the large massage contact head 12 to rotate through the connecting ring 15. During this process, the movable connection between the bushing 11 and the connecting rod 16 does not affect the movement of the connecting rod 16. The large massage contact head 12 is movably connected to the small massage contact head 7 through the bearing 13, and the movable connection with the connecting rod 16 ensures that the small massage contact head 7 can work normally, so that all components of the entire massager work together to achieve multi-mode massage function.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
