Description

Technical Field

[0001] This invention relates to the field of massage equipment technology, specifically to a highly adaptable massager whose massage head can circulate along a set running trajectory to achieve massage of the human body along a specific path. Background Technology

[0002] Massagers are simulated health care devices developed based on physics, bionics, bioelectricity, traditional Chinese medicine, and years of clinical practice. They utilize several independent soft-touch massage heads to relax muscles, soothe nerves, promote blood circulation, enhance cell metabolism, and improve skin elasticity. They can relieve fatigue, significantly reduce various chronic and acute pains and muscle soreness, relax the body, and reduce stress.

[0003] Existing massagers generally consist of a housing and massage heads mounted on the housing. A drive mechanism, such as an electric motor, rotates the massage heads, causing them to move in a circular motion to massage the body. However, because the massage heads can mostly only move in a circular path under the drive mechanism, they cannot move along a specific trajectory that better adapts to the curves of the human body, making it difficult to effectively improve the massage experience.

[0004] Therefore, the research objective of this invention is to design a highly adaptable massager that enables the massage head to circulate along a set trajectory to massage the human body along a specific path, thereby effectively and significantly improving the massage experience. Summary of the Invention

[0005] In view of the technical problems existing in the prior art, the present invention provides a highly adaptable massager that can effectively solve the technical problems existing in the prior art.

[0006] The technical solution of this invention is:

[0007] A highly adaptable massager, comprising:

[0008] chassis;

[0009] The drive shaft, driven by a corresponding electric motor, is mounted on the housing.

[0010] A rotary joint is fixedly installed at the end of the drive shaft and rotates with the drive shaft;

[0011] A sliding rod is circumferentially movably mounted on the rotary joint, and the sliding rod rotates with the drive shaft or the rotary joint;

[0012] The guiding mechanism guides the sliding rod during its rotation, causing it to move circumferentially along a set running trajectory.

[0013] At least one massage head is mounted on the sliding rod;

[0014] The guiding mechanism includes a track groove disposed on the housing, the beginning and end of the track groove being seamlessly connected to form a continuous guide rail. The sliding rod is provided with a guide component that engages with the track groove. During the rotation of the sliding rod, the guide component moves along the track groove to drive the sliding rod to move circumferentially along a set running trajectory.

[0016] The housing includes a base housing, on which gear set mounting cavities and motor mounting cavities are arranged side-by-side at intervals. A corresponding first transmission gear set is assembled in the gear set mounting cavity. A drive shaft is driven to the output end of the first transmission gear set, and the ends of the drive shaft extend to the outside of the gear set mounting cavity. The motor is fixedly installed in the motor mounting cavity. The input end of the first transmission gear set is driven to the output shaft end of the motor through a transversely arranged gear shaft. A top cover plate for forming a closure between the gear set mounting cavity and the motor mounting cavity is detachably installed on the upper part of the base housing. The track groove is provided on the base housing outside the gear set mounting cavity and on the top cover plate.

[0017] The sliding rod rotates with the rotary joint, which includes a fixed seat mounted on the inner side of the end of the drive shaft. A mounting seat that snaps onto the end of the drive shaft is detachably mounted on the outer side of the fixed seat. An insertion hole for the drive shaft to pass through is provided between the middle of the mounting seat and the fixed seat. The sliding rod is circumferentially movable and inserted into the insertion hole. The middle of the sliding rod is provided with a snap-fit ​​elongated hole that is in line contact with the drive shaft. The drive shaft rotates to drive the fixed seat and the mounting seat to rotate. During the rotation of the fixed seat and the mounting seat, the sliding rod is driven to rotate.

[0018] The mounting base is provided with a guide groove for limiting the sliding rod. The groove opening of the guide groove is provided with a corresponding snap-fit ​​protrusion. The fixing base is provided with a slot for locking the snap-fit ​​protrusion. After the mounting base and the fixing base are assembled, the snap-fit ​​protrusion is inserted into the slot of the fixing base. The bottom of the guide groove and the slot cooperate to form the insertion hole.

[0019] The middle part of the snap-fit ​​protrusion is provided with corresponding limiting slots, and the side wall of the slot is provided with limiting blocks corresponding to the limiting slots.

[0020] A set of corresponding support protrusions is provided between the snap-fit ​​protrusion and the inner wall of the guide groove. The inner ends of the support protrusions are respectively arc-shaped and abut against the sliding rod in a line contact manner.

[0021] The end of the drive shaft is provided with at least one first drive plane. The outer side of the mounting base is integrally formed with a corresponding connecting block. The interior of the connecting block is provided with a mounting hole that extends through to the mounting base and is adapted to the first drive plane of the drive shaft. The mounting base is fixedly snapped onto the drive shaft by cooperating with the end of the drive shaft through the mounting hole. Then, the connecting block is locked onto the drive shaft by a corresponding locking screw.

[0022] Alternatively, the housing includes a housing body and a mounting cover detachably mounted on the housing body. A corresponding second transmission gear set is installed inside the mounting cover. The drive shaft is driven to the output end of the second transmission gear set. The motor is fixedly installed inside the mounting cover. The output end of the second transmission gear set is driven to the output shaft end of the motor. The track groove is integrally disposed on the side wall of the mounting cover.

[0023] Alternatively, the sliding rod rotates with the drive shaft, and the rotary joint includes a fixed seat mounted on the inner side of the end of the drive shaft. A mounting seat that snaps onto the end of the drive shaft is detachably mounted on the outer side of the fixed seat. An insertion hole for the drive shaft to pass through is provided between the middle of the mounting seat and the fixed seat. At least one second driving plane is provided on the drive shaft, and the second driving plane extends into the insertion hole. The sliding rod is circumferentially movable and inserted into the insertion hole. The middle of the sliding rod is provided with a snap-fit ​​elongated hole that is in surface contact with the second driving plane of the drive shaft. The drive shaft rotates to drive the sliding rod to rotate through the second driving plane.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0025] 1) Based on the drive shaft, the present invention further adds a rotary joint, which is fixedly installed at the end of the drive shaft and rotates with the drive shaft; then, a sliding rod is movably installed circumferentially on the rotary joint, so that the sliding rod can rotate with the drive shaft or the rotary joint; based on this, the present invention further adds a guide mechanism, which guides the sliding rod in real time during the rotation of the sliding rod, so that the sliding rod moves circumferentially along a set running trajectory, thereby driving the massage head to circumferentially move along the set running trajectory, so as to achieve massage of the human body under a specific path, thereby effectively and significantly improving the massage experience.

[0026] 2) The guiding mechanism of the present invention includes a track groove disposed on the housing. The head and tail of the track groove are seamlessly connected to form a continuous guide rail. A guide component is disposed on the sliding rod and engaged in the track groove. During the rotation of the sliding rod, the guide component moves directly along the track groove, thereby driving the sliding rod to move circumferentially along the set running trajectory. This ensures real-time position guidance during the rotation of the sliding rod, thus effectively ensuring the practical effect of the present invention.

[0027] 3) The housing of this invention includes a base housing, on which gear assembly cavities and motor assembly cavities are arranged side-by-side at intervals. After the power source (motor), the first transmission gear set, and the various components of this invention are assembled into their respective positions, the top cover plate can be installed. This significantly reduces the difficulty of assembling the various components of this invention. Furthermore, after assembly, the motor and other components are evenly distributed in the gear assembly cavities, motor assembly cavities, and on both sides of the gear assembly cavities, effectively overcoming the problem of highly concentrated vibration transmitted to the massage head caused by the concentrated installation of the motor and other components.

[0028] 4) The sliding rod of the present invention rotates with the rotary joint, which includes a fixed seat mounted on the inner side of the end of the drive shaft. A mounting seat that snaps onto the end of the drive shaft is detachably mounted on the outer side of the fixed seat. An insertion hole for the drive shaft to pass through is provided between the middle of the mounting seat and the fixed seat. The sliding rod is circumferentially movable and inserted into this insertion hole. The middle of the sliding rod has a snap-fit ​​elongated hole that is in line contact with the drive shaft. During operation, the drive shaft rotates to drive the fixed seat and the mounting seat to rotate. The rotation of the fixed seat and the mounting seat causes the sliding rod to rotate, and the sliding rod moves circumferentially along a set running trajectory during rotation. During this process, the sliding rod only has line contact with the drive shaft, thus satisfying the reasonable assembly of the rotary joint, the sliding rod, and the drive shaft, and reducing the friction of the sliding rod during circumferential movement, thereby effectively ensuring the practical effect of the present invention.

[0029] 5) The mounting base of the present invention is provided with a guide groove for limiting the sliding rod. A corresponding engaging protrusion is provided at the opening of the guide groove. The fixed base is provided with a locking groove for locking the engaging protrusion. After the mounting base and the fixed base are assembled, the engaging protrusion is inserted into the locking groove of the fixed base, so that the bottom of the guide groove and the locking groove cooperate to form an insertion hole. This concentrates all the force on the sliding rod during the massage process onto the mounting base beforehand, and then distributes it to the fixed base, ensuring the assembly stability between the fixed base and the mounting base during the force application process, thereby further ensuring the practical effect of the present invention.

[0030] 6) The middle part of the snap-fit ​​protrusion of the present invention is provided with corresponding limiting sockets, and the side wall of the slot is provided with a limiting block corresponding to the limiting socket. After the mounting base and the fixing base are assembled, the limiting block is further inserted into the limiting socket to further improve the assembly stability between the fixing base and the mounting base during the force process.

[0031] 7) A set of corresponding support protrusions are respectively provided between the snap-fit ​​protrusion and the inner wall of the guide groove of the present invention. The inner ends of the support protrusions are respectively arranged in an arc shape and abut against the sliding rod in a line contact manner, so as to further reduce the friction of the sliding rod during circumferential movement.

[0032] 8) The sliding rod of the present invention rotates with the drive shaft, and the drive shaft is provided with at least one second drive plane. The second drive plane extends into the insertion hole formed by the mounting base and the fixed base. The sliding rod is circumferentially movable and inserted into the insertion hole. The middle part of the sliding rod is provided with a snap-fit ​​elongated hole that is in surface contact with the second drive plane of the drive shaft, so that the driving force of the drive shaft is directly transmitted to the position through the second drive plane to realize the rotation drive of the sliding rod. At this time, the rotary joint only needs to provide guide support, thereby effectively improving the driving effect of the sliding rod and reducing the force requirements of the rotary joint.

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0043] Example 1

[0044] refer to Figure 1-4 A highly adaptable massager, comprising:

[0045] Casing 1;

[0046] The drive shaft 2 is driven to rotate on the housing 1 by a corresponding electric motor 3;

[0047] Rotary joint 4 is fixedly installed at the end of the drive shaft 2 and rotates with the drive shaft 2;

[0048] The sliding rod 5 is circumferentially movable on the rotary joint 4, and the sliding rod 5 rotates with the drive shaft 2 or the rotary joint 4;

[0049] The guiding mechanism 6 guides the sliding rod 5 during its rotation, causing the sliding rod 5 to move circumferentially along a set running trajectory;

[0050] A set of massage heads 7 are respectively installed at both ends of the sliding rod 5;

[0051] The guiding mechanism 6 includes a track groove 601 disposed on the housing 1. The head and tail of the track groove 601 are seamlessly connected to form a continuous guide rail. The sliding rod 5 is provided with a guide component 602 that is engaged in the track groove 601. During the rotation of the sliding rod 5, the guide component 602 moves along the track groove 601 to drive the sliding rod 5 to move circumferentially along a set running trajectory.

[0052] Based on the drive shaft 2, this invention further adds a rotary joint 4, which is fixedly installed at the end of the drive shaft 2 and rotates with the drive shaft 2. Then, a sliding rod 5 is circumferentially movably installed on the rotary joint 4, so that the sliding rod can rotate with the drive shaft 2 or the rotary joint 4. On this basis, this invention further adds a guide mechanism 6, which guides the sliding rod 5 in real time during its rotation, so that the sliding rod 5 moves circumferentially along a set running trajectory, thereby driving the massage head 7 to circumferentially move along the set running trajectory, so as to achieve massage of the human body under a specific path, thereby effectively and significantly improving the massage experience.

[0053] In this embodiment, the guide component 602 includes a limiting shaft 6021 fixed to the sliding rod 5. A limiting wheel 6022 adapted to the track groove 601 is rotatably mounted on the limiting shaft 6021. During the rotation of the sliding rod 5, the limiting wheel 6022 moves around the track groove 601 to effectively guide the sliding rod 5 in real time, thereby ensuring the practical effect of the present invention.

[0054] The housing 1 includes a base housing 101. Gear set mounting cavities 8 and motor mounting cavities 9 are arranged side by side at intervals on the base housing 101. A corresponding first transmission gear set 10 is assembled in the gear set mounting cavity 8. The drive shaft 2 is driven to the output end of the first transmission gear set 10. The end of the drive shaft 2 extends to the outside of the gear set mounting cavity 8. The motor 3 is fixedly installed in the motor mounting cavity 9. The input end of the first transmission gear set 10 is driven to the output shaft end of the motor 3 through a transversely arranged gear shaft 11. The upper part of the base housing 101 is detachably equipped with an upper cover plate 102 for forming a closure between the gear set mounting cavity 8 and the motor mounting cavity 9. The track groove 601 is disposed on the base housing 101 and the upper cover plate 102 outside the gear set mounting cavity 8.

[0055] The housing 1 of this invention includes a base housing 101, on which gear set mounting cavities 8 and motor mounting cavities 9 are arranged side-by-side at intervals. After the power source (motor 3), the first transmission gear set 10, and the various components of this invention are respectively assembled into place, the upper cover plate 102 can be installed into place, thereby significantly reducing the difficulty of assembling the various components of this invention. Moreover, after assembly, the motor 3 and other components are evenly distributed in the gear set mounting cavities 8 and 9 of the housing 1, as well as on both sides of the gear set mounting cavities 8, thereby effectively overcoming the problem of highly concentrated transmission of operating vibrations to the massage head 7 caused by the concentrated installation of the motor 3 and other components.

[0056] The sliding rod 5 rotates with the rotary joint 4. The rotary joint 4 includes a fixed seat 401 installed on the inner side of the end of the drive shaft 2. A mounting seat 402 that is snapped onto the end of the drive shaft 2 is detachably installed on the outer side of the fixed seat 401. An insertion hole for the drive shaft 2 to pass through is provided between the mounting seat 402 and the middle of the fixed seat 401. The sliding rod 5 is circumferentially movable and inserted into the insertion hole. The middle of the sliding rod 5 is provided with a snap-fit ​​elongated hole 501 that is in line contact with the drive shaft 2. The drive shaft 2 rotates to drive the fixed seat 401 and the mounting seat 402 to rotate. During the rotation of the fixed seat 401 and the mounting seat 402, the sliding rod 5 is driven to rotate.

[0057] During operation, the drive shaft 2 rotates to drive the fixed base 401 and the mounting base 402 to rotate. As the fixed base 401 and the mounting base 402 rotate, they cause the sliding rod 5 to rotate. During this rotation, the sliding rod 5 moves circumferentially along a predetermined trajectory. In this process, the sliding rod 5 only makes line contact with the drive shaft 2, thus satisfying the reasonable assembly of the rotary joint 4, the sliding rod 5, and the drive shaft 2, and reducing the friction of the sliding rod 5 during circumferential movement, thereby effectively ensuring the practical effect of the invention.

[0058] The mounting base 402 is provided with a guide groove 12 for limiting the sliding rod 5. A corresponding engaging protrusion 13 is provided at the opening of the guide groove 12. The fixing base 401 is provided with a locking groove 14 for locking the engaging protrusion 13. After the mounting base 402 and the fixing base 401 are assembled, the engaging protrusion 13 is inserted into the locking groove 14 of the fixing base 401. The bottom of the guide groove 12 and the locking groove 14 cooperate to form the insertion hole. In this way, the force on the sliding rod 5 during the massage process can be pre-concentrated on the mounting base 402, and then distributed to the fixing base 401 through the mounting base 402, ensuring the assembly stability between the fixing base 401 and the mounting base 402 during the force application process, thereby further ensuring the practical effect of the present invention.

[0059] The middle portion of the snap-fit ​​protrusion 13 is provided with a corresponding limiting socket 15, and the side wall of the slot 14 is provided with a limiting block 16 corresponding to the limiting socket 15. After the mounting base 402 and the fixing base 401 are assembled, the limiting block 16 is further inserted into the limiting socket 15 to further improve the assembly stability between the fixing base 401 and the mounting base 402 during the force process.

[0060] A set of corresponding support protrusions 17 are respectively provided between the snap-fit ​​protrusion 13 and the inner wall of the guide groove 12. The inner ends of the support protrusions 17 are respectively arranged in an arc shape and abut against the sliding rod 5 in a line contact manner. In this way, the friction of the sliding rod 5 during circumferential movement can be further reduced, thereby further improving the practical effect of the present invention.

[0061] The end of the drive shaft 2 is provided with at least one first drive plane 18. The outer side of the mounting base 402 is integrally formed with a corresponding connecting block 19. The interior of the connecting block 19 is provided with a mounting hole that extends through to the mounting base 402 and is adapted to the first drive plane 18 of the drive shaft 2. The mounting base 402 is fixedly snapped onto the drive shaft 2 by cooperating with the end of the drive shaft 2 through the mounting hole, and the connecting block 19 is locked onto the drive shaft 2 by a corresponding locking screw.

[0062] Example 2

[0063] refer to Figure 5-7 The difference between this embodiment and Embodiment 1 is that: the housing 1 includes a housing body 103 and a mounting cover 104 detachably mounted on the housing body 103. A corresponding second transmission gear set 20 is installed inside the mounting cover 104. The drive shaft 2 is driven to the output end of the second transmission gear set 20. The motor 3 is fixedly mounted inside the mounting cover 104. The output end of the second transmission gear set 20 is driven to the output shaft end of the motor 3. The track groove 601 is integrally disposed on the side wall of the mounting cover 104.

[0064] The sliding rod 5 rotates with the drive shaft 2. The rotary joint 4 includes a fixed seat 401 installed on the inner side of the end of the drive shaft 2. A mounting seat 402 that is snapped onto the end of the drive shaft 2 is detachably installed on the outer side of the fixed seat 401. An insertion hole for the drive shaft 2 to pass through is provided between the middle of the mounting seat 402 and the fixed seat 401. At least one second driving plane 21 is provided on the drive shaft. The second driving plane 21 extends into the insertion hole. The sliding rod 5 is circumferentially movable and inserted into the insertion hole. The middle of the sliding rod 5 is provided with a snap-fit ​​elongated hole 501 that is in surface contact with the second driving plane 21 of the drive shaft 2. The drive shaft 2 rotates to drive the sliding rod 5 to rotate through the second driving plane 21.

[0065] In this embodiment, the sliding rod 5 rotates with the drive shaft 2. The drive shaft 2 is provided with a set of second drive planes 21. The second drive planes 21 extend into the insertion hole formed by the mounting base 402 and the fixed base 401. The sliding rod 5 is circumferentially movable and inserted into the insertion hole. The middle part of the sliding rod 5 is provided with a snap-fit ​​elongated hole 501 that is in surface contact with the second drive plane 21 of the drive shaft 2. Thus, the driving force of the drive shaft 2 is directly transmitted to the position through the second drive plane 21 to realize the rotation drive of the sliding rod 5. At this time, the rotary joint 4 only needs to provide guide support, which can effectively improve the driving effect of the sliding rod 5 and reduce the force requirements of the rotary joint 4.

[0066] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.

[0067] Example 3

The fixing block has a central insertion hole for the drive shaft 2 to pass through. The sliding rod 5 is circumferentially movable and inserted into the insertion hole. Furthermore, the sliding rod 5 has a central locking elongated hole 501 for engaging with the drive shaft 2. This integrated fixing block effectively ensures the overall rigidity and strength of the rotary joint 4.

[0069] It should be noted that this embodiment is implemented in the same way as embodiment one in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in embodiment one.
