Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, specifically to a massager. Background Technology

[0002] Most massagers currently on the market rely on traditional mechanical transmission structures. Their core principle involves multiple gears and drive shafts meshing together to form a transmission mechanism, thereby transferring energy from a power source to the massage mechanism. This transmission method has significant limitations: firstly, due to constraints in the size, material, and meshing precision of the gears and drive shafts, the output torque is insufficient to meet diverse massage needs. For example, for deep muscle relaxation, a larger torque is required to effectively relieve muscle tension, but existing structures have limited output torque, resulting in insufficient massage intensity and failing to achieve the desired massage effect, thus hindering the true relaxation and fatigue relief.

[0003] On the other hand, this type of transmission structure has a complex design, with numerous gears forming a vast mechanical network. Due to inherent errors in the manufacturing precision and assembly process of each component, these connection points are prone to wear and misalignment after prolonged use. Once this occurs, the normal meshing between gears will be disrupted, leading to jamming. This malfunction not only interrupts the massage process and affects the user experience, but may also damage critical components such as the motor due to excessive stress on local parts, significantly shortening the lifespan of the massager, increasing maintenance costs, and adding to user inconvenience.

[0054] Compared with the prior art, the present invention has the following beneficial effects:

[0055] 1. This utility model adopts a power output method that combines an electric motor and a planetary gear reducer, which fundamentally solves the problems of insufficient torque and complex structure. In terms of power transmission, the electric motor is the core power source. Through a precisely matched planetary gear reducer, the power is efficiently amplified. With its unique planetary gear system structure, the planetary gear reducer uses multiple planetary gears to evenly distribute the load, which can withstand higher input speeds and achieve a larger transmission ratio in a limited space, thereby outputting strong and stable torque.

[0056] 2. Compared to the numerous gears and drive shafts connected in series in traditional structures, planetary gear reducers employ a modular design with a compact internal gear layout. This reduces unnecessary intermediate transmission components and connection points, simplifying mechanical assembly and significantly reducing friction and wear between components. This fundamentally lowers the likelihood of jamming due to component wear or misalignment. Furthermore, the simplified structure allows for a more rational internal space layout within the massager, enabling subsequent miniaturization and lightweight design, further enhancing user convenience and market competitiveness.

[0107] Working principle:

[0108] a. The principle behind the kneading and massage effect:

[0109] like Figure 3 and Figure 5 As shown, when the motor 31 rotates, the drive shaft of the motor 31 drives the second-stage spur gear 321 to rotate through the planetary gear reducer 32. The second-stage spur gear 321 drives the first-stage spur gear 331 to rotate, which in turn drives the kneading shaft 33 to rotate. The kneading shaft 33 drives the first eccentric wheel 332, the first eccentric wheel 333, the second eccentric wheel 334, the second eccentric wheel 335, the first eccentric wheel fixing seat 336, and the second eccentric wheel fixing seat 337 to rotate, which in turn drives the first left massage bracket 4112, the second left massage bracket 4122, the first right massage bracket 4212, and the second right massage bracket 4222 to move.

[0110] like Figure 5 and Figure 14 As shown, the first limiting post 4121 at the bottom of the second left massage bracket 4122 is limited by the first limiting groove 13. At the same time, the second left massage bracket 4122 is driven by the first oscillating wheel 333, so that the second left massage head 4123 on the second left massage bracket 4122 oscillates within a certain range.

[0111] like Figure 5 and Figure 9As shown, the first left massage bracket 4112 is constrained by the first tapping rod 342 connected to the first universal joint 4111 on the first left massage bracket 4112, and is driven by the first eccentric wheel 332, so that the first left massage head 4113 on the first left massage bracket 4112 can swing its arm when the kneading shaft 33 rotates. In conjunction with the second left massage head 4123 on the swinging second left massage bracket 4122, the kneading and clamping massage effect can be achieved.

[0112] like Figure 5 and Figure 15 As shown, the second limiting post 4221 at the bottom of the second right massage bracket 4222 is limited by the second limiting groove 14. At the same time, the second right massage bracket 4222 is driven by the second oscillating wheel 335, so that the second right massage head 4223 on the second right massage bracket 4222 can oscillate within a certain range.

[0113] like Figure 5 and Figure 11 As shown, the first right massage bracket 4212 is constrained by the second tapping rod 346 connected to the second universal bracket 4211 on the first right massage bracket 4212, and is driven by the second eccentric wheel 334, so that the first right massage head 4213 on the first right massage bracket 4212 can swing its arm when the kneading shaft 33 rotates. In conjunction with the second right massage head 4223 on the swinging second right massage bracket 4222, a kneading and clamping massage effect can be achieved.

[0114] When the kneading shaft 33 rotates, the right side of the first sway wheel fixing seat 336 and the left side of the first sway wheel 333 simultaneously form an angle with the kneading shaft 33, performing an inclined plane motion. The second left massage bracket 4122 is sandwiched between the two surfaces. Under the constraint of the first limiting post 4121 and the first limiting groove 13, the second left massage bracket 4122 swings left and right, thereby causing the entire second left massage assembly 412 to swing left and right. Similarly, the second right massage assembly 422 also swings left and right.

[0115] When the kneading shaft 33 rotates, the first eccentric wheel 332 is eccentric to the kneading shaft 33, and the left side of the first eccentric wheel 332 forms an angle with the kneading shaft 33. The first eccentric inclined surface 3331 of the first eccentric wheel 333 also forms an angle with the kneading shaft 33. The first left massage bracket 4112 is sandwiched between the two surfaces, and the first universal joint 4111 will change positions, causing the first left massage bracket 4112 to swing left and right, which in turn causes the entire first left massage assembly 411 to swing left and right. Similarly, the first right massage assembly 421 also swings left and right.

[0116] b. The principle behind the tapping massage effect:

[0117] like Figure 4, Figure 9 , Figure 10 As shown, when the motor 31 rotates, the drive shaft of the motor 31 drives the small pulley 311 to rotate. The small pulley 311 drives the large pulley 341 to rotate through the annular transmission belt 35, which in turn drives the striking shaft 34 to rotate. The striking shaft 34 drives the first striking seat 349 and the second striking seat 345 to rotate.

[0118] The first tapping seat 349 drives the first left massage bracket 4112 to rotate on the first eccentric wheel 332 via the first tapping rod 342, which in turn drives the first left massage head 4113 to perform a tapping action, achieving a tapping massage effect. The first tapping pivot 343, the first universal ball head 344, and the first universal bracket 4111 allow the first tapping seat 349 to rotate, thereby driving the first left massage bracket 4112 to move.

[0119] The second striking seat 345 drives the first right massage bracket 4212 to rotate on the second eccentric wheel 334 via the second striking rod 346, which in turn drives the first right massage head 4213 to perform a striking action, achieving a striking massage effect. The second striking pivot 347, the second universal ball head 348, and the second universal bracket 4211 allow the second striking seat 345 to rotate, thereby driving the first right massage bracket 4212 to move.

[0120] Furthermore, the first bearing 23 and the second bearing 24 can be set as one-way needle roller bearings. When the motor 31 moves forward, the first bearing 23 and the second bearing 24 are locked, the annular transmission belt 35 rotates normally, but does not drive the tapping shaft 34 to rotate, thus not achieving the tapping massage effect. When the motor 31 reverses, the first bearing 23 and the second bearing 24 are rotatable, the annular transmission belt 35 rotates normally, and drives the tapping shaft 34 to rotate, thus achieving the tapping massage effect. By adjusting the rotation direction of the motor 31, it can be determined whether the tapping massage effect is achieved simultaneously with the kneading massage effect.

[0121] This invention enables the massager to output greater torque and achieve a better massage effect by setting a planetary gear reducer, while simplifying the internal structure of the massager.
