Description

Technical Field

[0001] This invention belongs to the field of massager technology, and particularly relates to portable massagers. Background Technology

[0002] With the accelerated pace of modern life and increased work pressure, problems such as shoulder and neck pain, lower back fatigue, and muscle tension caused by prolonged sitting, lack of exercise, and poor posture have become increasingly common and affect younger people. At the same time, people's pursuit of quality of life and physical and mental health is constantly improving.

[0003] While traditional professional physiotherapy and massage services are effective, they have limitations such as high time costs, high expenses, and poor convenience, failing to meet the public's daily and immediate relaxation needs. Massagers with kneading and tapping functions are generally bulky and difficult to carry, making it impossible for users to perform targeted muscle relaxation and relieve fatigue anytime and anywhere during fragmented time such as office lunch breaks, business trips, or watching TV at home. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing a portable massager that integrates kneading and tapping functions and has a compact structure, thus solving the problem that massagers cannot be carried and used anytime and anywhere.

[0005] The technical solution of the present invention: a portable massager, including a housing, a driving device, and a massage head assembly including a plurality of massage heads. The housing is provided with a kneading and tapping component that drives the massage heads to move. The kneading and tapping component includes a mounting base rotatably disposed in the housing. Each massage head of the massage head assembly is evenly distributed circumferentially on the top surface of the mounting base. Each massage head is movably disposed on the mounting base. The driving device is connected to the mounting base to drive the mounting base to rotate. The kneading and tapping assembly also includes a tapping component disposed within the housing. The tapping component has an annular track groove on its circular outer circumferential surface. The upper and lower sidewalls of the track groove are smoothly undulating in the up-and-down movement direction of the massage head. A rolling component is rotatably disposed on the massage head. The rolling component is placed in the track groove and rolls on the upper or lower sidewall of the track groove. When the mounting base and the striking element rotate relative to each other, the massage head performs a reciprocating motion up and down under the combined action of the track groove and the rolling element.

[0006] By adopting the above technical solution, the rotation of the mounting base is driven by the drive device to realize the circumferential motion of each massage head, thereby achieving the kneading massage action. At the same time, the massage heads cooperate with the track groove during rotation, so that each massage head can move up and down during circumferential rotation, thereby achieving the tapping massage action. Thus, by combining the rotation of the mounting base and the track groove, the two massage actions of kneading and tapping are integrated to achieve a compound massage effect. Meanwhile, the overall structure is simple and compact, ensuring that the overall structure is small and portable.

[0007] A further feature of the present invention is that the massage head assembly is provided in two groups, with the same number of massage heads in both groups. Each massage head assembly is provided with a corresponding kneading and tapping component, and the mounting seats of the two kneading and tapping components are rotated in opposite directions.

[0008] With the above-mentioned further configuration, the two massage head groups with opposite directions not only increase the massage coverage area, but also allow for kneading movements in different directions, achieving a better massage effect to relax muscles.

[0009] A further feature of the present invention is that each kneading and tapping component includes a first gear fixedly mounted on the outer peripheral surface of the corresponding mounting base. The output end of the driving device is connected to a first gear for transmission. A second gear and a third gear are sequentially meshed between the two first gears. The second gear and the third gear are rotatably connected to the housing through gear shafts.

[0010] With the above-mentioned further configuration, the two mounting seats can be rotated in opposite directions through gear transmission. The first gear can be arranged close to the outer periphery of the mounting seat, which is beneficial to control the size and volume of the entire massager. The second and third gears can be reliably installed on the housing through the gear shaft, ensuring that the center distance of gear meshing is fixed, the transmission is smooth, and there will be no abnormal noise or damage due to gear shaking.

[0011] A further feature of the present invention is that the striking element is rotatably disposed within the housing, and the striking element is connected to the output shaft of the driving device via a transmission connection.

[0012] With the above-mentioned further configuration, by also rotating the tapping component inside the housing, the tapping component can be driven to rotate, thereby driving the massage head to perform a reciprocating up-and-down tapping motion.

[0013] A further feature of the present invention is that the kneading and striking assembly also includes a drive shaft, which is fixedly mounted on the striking member. One end of the drive shaft is rotatably connected to the housing, and the other end is rotatably connected to the mounting base via a bearing.

[0014] With the above-mentioned further configuration, the drive shaft provides support at both ends for the striking part, forming a stable rotating shaft system. This ensures the smoothness and reliability of the striking part when it rotates in the opposite direction at high speed, reduces vibration and noise, and the bearings between the mounting base and the striking part can prevent mutual interference between their rotations.

[0015] A further provision of the present invention includes: a linkage assembly is provided inside the housing, the linkage assembly includes a linkage shaft, both ends of the linkage shaft are respectively mounted on a bearing seat via bearings, the bearing seat is fixedly connected to the housing, the output end of the drive device is drivenly connected to the linkage shaft, and the linkage shaft is drivenly connected to two drive shafts.

[0016] By adopting the above-mentioned further configuration, by adding a linkage shaft stably supported by a bearing housing, the goal of controlling two striking parts simultaneously with a single drive device is achieved. This simplifies the transmission system, avoids configuring a separate drive source for each striking part, ensures the synchronization of the movement of the two striking parts, and makes the product structure more compact and more controllable.

[0017] A further embodiment of the present invention is as follows: the driving device is a motor, and two one-way bearings are fixedly mounted on its output shaft. The two one-way bearings are locked in opposite directions, and the outer rings of the two one-way bearings are respectively connected to the mounting base and the linkage shaft. The outer rings of the one-way bearings are connected to the mounting base or the linkage shaft through gear transmission or belt transmission.

[0018] With a further refinement, two one-way bearings with opposite locking directions are fixedly mounted on the motor output shaft. The forward and reverse rotation of the motor can drive the mounting base and the linkage shaft to rotate respectively. When the forward rotation drives the mounting base to rotate, the linkage shaft and the two tapping parts are locked, and the massage head performs a kneading motion in a circular motion, while simultaneously performing a slow tapping motion. When the reverse rotation drives the linkage shaft to rotate, the two tapping parts rotate and the mounting base is locked. At this time, the massage head only performs a rapid tapping motion in the up and down direction to achieve a deep tapping massage effect on the massage points.

[0019] A further feature of the present invention is that the top surface of the mounting base is provided with through holes evenly distributed circumferentially, the massage head includes one end inserted into the through hole and the other end extending out of the housing, the massage head is fixedly connected to a shaft, and the rolling element is rotatably connected to the shaft.

[0020] With the above-mentioned further design, the through hole provides precise guidance for the up-and-down movement of the massage head, preventing the massage head from swaying during movement and ensuring that the massage force acts vertically on the body. At the same time, the fixation of the massage head to the shaft and the installation of the rolling element on the shaft form a modular sub-component, which simplifies the structure and facilitates production and assembly.

[0027] like Figure 1-7 As shown, the portable massager includes a housing 1, a drive unit 2, a massage head assembly 3 including a plurality of massage heads 31, and a kneading and tapping component disposed within the housing 1.

[0028] The drive device 2 preferably uses a brushless motor, which is fixedly installed inside the housing 1. Its power supply can also be fixedly installed inside the housing 1. The housing 1 is composed of a cover plate and a box body that can be disassembled, which facilitates subsequent maintenance.

[0029] The kneading and tapping assembly includes a mounting base 4 rotatably disposed in the housing 1. Each massage head 31 of the massage head assembly 3 is evenly distributed circumferentially on the top surface of the mounting base 4. In this embodiment, a massage head assembly 3 includes three massage heads 31. The three massage heads 31 are evenly distributed circumferentially with the mounting base 4, and each massage head 31 is movably disposed on the mounting base 4. Specifically, the top surface of the mounting base 4 is evenly provided with several through holes 15 along the circumference. The number of through holes 15 corresponds to the number of massage heads 31, with three in each case. Each massage head 31 includes a rod at one end inserted into the through hole 15 and a head at the other end extending out of the housing 1. The head and rod of the massage head 31 are detachably connected, such as by a snap-fit ​​connection, to facilitate subsequent replacement of the massage head 31. The massage head 31 is fixedly connected to a shaft 32, and the shaft 32 is rotatably connected to a rolling element 7, which can be a bearing. In this design, the through holes 15 provide precise guidance for the up-and-down movement of the massage head 31 and the shaft 32, preventing them from swaying.

[0030] The kneading and tapping assembly also includes a tapping member 5 disposed within the housing 1. The outer wall of the tapping member 5 is provided with an annular track groove 6. The upper and lower sidewalls of the track groove 6 undulate smoothly in the up-and-down movement direction of the massage head 31. In this embodiment, the track groove 6 has a high point and a low point, and the area between the high point and the low point is a smooth surface. The rolling member 7 is placed in the track groove 6 and can roll on the upper or lower sidewall of the track groove 6.

[0031] In this embodiment, the massage head group 3 is provided in two groups, arranged side by side to increase the massage area. The two massage head groups 3 have the same number of massage heads 31. Each massage head group 3 is provided with an independent kneading and tapping component, which includes its own mounting base 4 and tapping component 5. The mounting bases 4 of the two kneading and tapping components are connected by transmission and rotate in opposite directions.

[0032] To achieve the opposite rotation of the two mounting seats 4, a first gear 8 is fixedly installed on the outer circumferential surface of each mounting seat 4. The output shaft of the drive device 2 is connected to one of the first gears 8. The two first gears 8 are linked by a second gear 9 and a third gear 10 meshing in sequence. The second gear 9 and the third gear 10 are rotatably connected to the housing 1 through their respective gear shafts 16, ensuring smooth and reliable transmission.

[0033] Furthermore, the striking element 5 is rotatably mounted on the housing 1, and its rotation direction is opposite to that of the mounting base 4 in the same component. To achieve this, the kneading and striking assembly also includes a drive shaft 11, which is fixedly mounted on the striking element 5. One end of the drive shaft 11 is rotatably connected to the housing 1 through a bearing, and the other end is rotatably connected to the mounting base 4 in the kneading and striking assembly through another bearing, providing stable support for both ends of the striking element 5.

[0034] In this embodiment, a driving device 2 drives two striking parts 5 simultaneously. A linkage assembly is also provided inside the housing 1. The linkage assembly includes a linkage shaft 12. Both ends of the linkage shaft 12 are respectively mounted on a bearing seat 13 fixed on the housing 1 through bearings to obtain stable support. The output end of the driving device 2 is connected to the linkage shaft 12, and the linkage shaft 12 is connected to two transmission shafts 11.

[0035] To enable the drive device 2 to drive the mounting base 4 and the striking element 5 to rotate respectively, two one-way bearings 20 are coaxially fixed on the output shaft of the drive device 2. The two one-way bearings 20 are locked in opposite directions. The outer rings of the two one-way bearings 20 are respectively connected to the mounting base 4 and the linkage shaft 12. One of the one-way bearings 20 has a gear installed on its outer ring, preferably a helical gear. This gear is connected to the first gear 8 through helical gear meshing. This can realize the transformation of the rotation of the output shaft of the horizontally placed drive device 2 into the vertically placed and rotating mounting base 4, which occupies a smaller vertical volume. The drive device 2 is set parallel to the two mounting bases 4. The internal structure of the massager is compact. The outer ring of the other one-way bearing 20 can be used as a driving pulley. A driven pulley is fixed on the linkage shaft 12. Thus, the one-way bearing 20 can be set to belt drive the linkage shaft 12, so that the motor can drive the mounting base and the linkage shaft to rotate in both forward and reverse directions respectively. Working principle: When the drive device 2 rotates forward, the inner and outer rings of one one-way bearing 20 rotate and lock, while the inner and outer rings of the other one-way bearing 20 rotate relative to each other. The relatively locked one-way bearing 20 drives the mounting base 4 to rotate through gear transmission. At this time, the other one-way bearing 20 rotates freely, and its outer ring lock cannot drive the linkage shaft 12 and the two tapping parts 5 to rotate. At this time, the massage head 31 moves in a circular motion with the mounting base 3 to achieve a kneading massage action. Due to the action of the track groove 6 and the rolling part 7, it performs a slow up-and-down tapping action synchronously. When the drive device 2 reverses and drives the linkage shaft 12 to rotate, the two tapping parts 5 rotate and the mounting base 4 locks. At this time, the massage head 31 only performs a rapid tapping action in the up-and-down direction to achieve a deep tapping massage effect on the massage points.

[0036] The combined action of the drive device 2 rotating forward: As the mounting base 4 carries the massage head 31 to revolve, while the striking element 5 rotates in the opposite direction, the rolling element 7 on the shaft of the massage head 31 is forced to roll relative to each other in the undulating track groove 6. The undulating contour of the track groove 6 forces the rolling element 7, together with the massage head 31, to continuously make up-down reciprocating movements while revolving, thereby realizing the striking action.
