Abstract

The utility model discloses a vibration massage head and a massage device, and relates to the field of massage equipment, and a magnet block is fixedly arranged in a metal seat to form an annular groove. A plurality of elastic pieces of the connecting piece are fixedly connected to the upper end of the metal base, and the vibration head, the connecting piece and the voice coil base are fixedly connected in sequence. The plurality of elastic sheets of the connecting sheet are fixedly arranged at the upper end of the metal seat, and the lower end of the voice coil seat is arranged in the annular groove in a vertically movable manner and is wound with a voice coil. The massage head is arranged outside other parts in a covering mode, and the upper end face of the vibration head protrudes out of the upper end of the massage head. During use, the voice coil is electrified to generate electromagnetism which interacts with the magnetic field of the magnet block, so that the vibration head moves up and down.

After the voice coil is electrified, the electromagnet and the magnet block interact with each other, and the vibration head can also move.

Description

Technical Field

[0001] This utility model relates to the field of massage equipment, specifically a vibrating massage head and massage device. Background Technology

[0002] For example, Chinese Patent No. CN215081957U discloses an audio vibration massager, which includes a magnetic shield, a magnet, a vibrating plate, a voice coil seat, and a massage head. The magnet is fixedly installed in the cavity of the magnetic shield. The upper part of the voice coil seat has a massage head, and the lower part is wound with a voice coil that extends between the magnet and the cavity wall. A vibration fixing ring is fixedly connected to the outer periphery of the voice coil seat, and the vibrating plate of the vibration fixing ring is fixedly connected to the magnetic shield. It has the following disadvantages: (1) The audio-controlled massage head always protrudes from the massage end of the massage device, making it difficult for the massage end to fit the human body, affecting the massage effect and comfort. (2) The connection structure of the voice coil seat, the vibration fixing ring, and the magnetic shield is not compact enough, resulting in a deviation in the size of the device, affecting the miniaturization of the device. Moreover, the elastic deformation ability of the vibrating plate of the vibration fixing ring is poor, and it is easy to undergo permanent deformation when subjected to a large external force, resulting in a poor massage effect. Summary of the Invention

[0003] The purpose of this invention is to provide a vibrating massage head and massage device, which aims to overcome the aforementioned problems existing in the prior art.

[0004] To achieve this objective, the present invention provides the following technical solution:

[0005] A vibrating massage head includes a mounting base, a massage head, a vibrating head, a magnet, a metal base, a connecting piece, a voice coil holder, and a voice coil. The magnet is fixed inside the metal base, and an annular groove is formed between the magnet and the metal base. A voice coil is arranged around the outer circumference of the voice coil holder. Several spring pieces are provided on the edge of the connecting piece. The metal base is fixedly connected to the mounting base, and several spring pieces are fixedly connected to the upper end of the metal base. The lower end of the connecting piece is fixedly connected to the voice coil holder, and the lower end of the voice coil holder is movably disposed inside the annular groove. The vibrating head is fixedly connected to the upper end of the connecting piece. The massage head has a mounting opening, and the massage head is fixedly connected to the mounting base, covering the vibrating head, the connecting piece, and the metal base. The vibrating head is movably disposed inside the mounting opening, and the upper end face of the vibrating head protrudes from the upper end of the mounting opening.

[0006] Furthermore, the aforementioned spring includes an inner end, an outwardly protruding arc segment, a U-shaped bend segment, an arc segment that bends back and forth, and an outer end connected in sequence. The inner end is integrally formed and fixed to the connecting piece, and the outer end is detachably fixed to the upper end of the metal base.

[0007] Furthermore, the upper surface of the aforementioned vibrating head protrudes 2mm-5mm beyond the upper end of the mounting port.

[0008] Furthermore, the number of the aforementioned spring clips is four, arranged in a ring around the edge of the connecting piece.

[0009] Furthermore, it also includes an O-ring. The aforementioned vibrating head has an annular recess, the inner side of the O-ring is embedded in the annular recess, and the outer side is tightly attached to the inner wall of the mounting opening.

[0010] Furthermore, it also includes vibration damping pads, which are sandwiched between the metal base and the mounting base.

[0011] The present invention also discloses a massage device, including a walking frame, the walking frame being movably provided with two swing arms, one end of which is fixedly provided with a vibrating massage head as described in any of the above claims.

[0012] Furthermore, it also includes an audio circuit; the two ends of the voice coil are electrically connected to the output terminal of the audio circuit, and the audio signal output by the audio circuit is used to energize the voice coil to generate electromagnetic waves.

[0013] Furthermore, the aforementioned audio circuit includes an audio signal processing module and an audio power amplifier module. The output terminal of the audio signal processing module is connected to the input terminal of the audio power amplifier module, and the left and right channel audio signals of the audio power amplifier module are electrically connected to the left and right vibrating massage heads, respectively.

[0014] Furthermore, a massage roller is installed at the other end of the swing arm.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] Firstly, in this invention, the magnet is fixed inside the metal base, forming an annular groove. Several spring pieces of the connecting plate are fixedly connected to the upper end of the metal base, and the vibrating head, connecting plate, and voice coil seat are sequentially fixedly connected. Several spring pieces of the connecting plate are fixed to the upper end of the metal base, and the lower end of the voice coil seat is movably positioned in the annular groove, with a voice coil wound around it. The massage head is covered outside the other components, and the upper surface of the vibrating head protrudes from the upper end of the massage head. During use, the voice coil is energized to generate electromagnetic waves, which interact with the magnetic field of the magnet, causing the vibrating head to move up and down. Because the upper end of the vibrating head protrudes from the upper end of the mounting opening, when the massage head is in contact with the human body, the vibrating head is in a compressed state (i.e., the spring pieces are elastically deformed downwards), ensuring constant contact between the vibrating head and the human body. After the voice coil is energized, the electromagnetic waves interact with the magnet, also causing the vibrating head to move (i.e., the spring pieces also undergo elastic deformation). The combined elastic deformation of both ensures that the vibrating head is always in contact with the human body, resulting in a stronger vibration and better comfort.

[0017] Secondly, the spring sheet includes an inner end, an outwardly protruding arc segment, a U-shaped bend segment, an arc segment that bends back and forth, and an outer end, which can optimize the stress distribution of the spring sheet, so that the spring sheet can maintain elastic deformation even when subjected to large external forces, and will not undergo permanent deformation.

[0018] Thirdly, the inner side of the O-ring is nested within the vibrating head, while the outer side is tightly fitted against the inner wall of the mounting opening. This solves the guidance problem and prevents the vibrating head from contacting the massage head and causing abnormal noise during vibration. A vibration damping pad is sandwiched between the metal base and the mounting base, reducing the transmission of vibration energy and making the device more stable and reliable.

[0019] Fourth, the upper end of the vibrating head protrudes 2mm-5mm from the upper end of the mounting port, which allows the vibrating head to retract into the mounting port when lightly pressed, ensuring that the vibrating head is always in contact with the human body while avoiding the vibrating head protruding too high and affecting comfort.

[0020] Fifth, in this utility model, the arm of the massage device is equipped with a vibrating massage head, and the voice coil of the vibrating massage head is electrically connected to the output terminal of the audio circuit. Since the audio signal is a constantly changing electrical signal (a continuous analog signal), the electromagnetic field generated by the energization of the voice coil changes continuously, thereby causing the amplitude and frequency of the up-and-down movement of the massage head to change continuously with the change of the audio signal, realizing the linkage between the audio and the massage head.

[0030] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of this utility model; however, those skilled in the art can implement this utility model without these details.

[0031] like Figures 1-7 As shown, a vibrating massage head mainly includes a mounting base 10, a massage head 2, a vibrating head 1, a magnet block 8, a metal base 7, a connecting piece 4, a voice coil base 5, and a voice coil 6.

[0032] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the mounting base 10 is, but is not limited to, a metal product, which is a plate and has a first mounting hole 102 for fixing the massage head body 2, a second mounting hole 103 for fixing the metal base 7, and a connecting ear 101 for fixing the swing arm 200.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the magnet block 8 is a permanent magnet, which is fixed inside the metal base 7, and an annular groove 708 is formed between the magnet block 8 and the metal base 7. The metal base 7 can concentrate the magnetic field lines inside the annular groove 708, thereby improving the utilization rate of the magnetic field.

[0034] like Figure 1 , Figure 2 and Figure 5 As shown, the voice coil holder 5 is, but is not limited to, an aluminum alloy product or a plastic product. The upper end of the voice coil holder 5 is a closed end. A voice coil 6 is arranged around the outer circumference of the voice coil holder 5. The voice coil 6 is used to generate electromagnetic fields when energized.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the connecting piece 4 is, but is not limited to, a thin metal sheet. The edge of the connecting piece 4 is provided with several spring tabs 41. The number of spring tabs 41 is, but is not limited to, four, and the four spring tabs 41 are arranged in a ring around the edge of the connecting piece 4.

[0036] Preferably, the spring piece 41 includes an inner end 411 integrally formed and fixed to the connecting piece 4, an outwardly protruding arc segment 412, a U-shaped bend segment 413, an arc segment 414 that bends back and forth, and an outer end 415 connected in sequence. The outer end 415 is provided with a mounting hole for detachably fixing it to the metal base 7. The bending design of the arc segment 412 allows the spring piece to undergo smooth elastic deformation when subjected to external force, reducing local stress concentration and improving the fatigue life of the spring piece. Furthermore, the protruding portion of the arc segment 412 provides additional elastic support, enhancing the elastic performance of the spring piece. The design of the U-shaped bend segment 413 amplifies the elastic deformation of the spring piece, allowing it to generate a large elastic displacement even under a small external force, thus providing a greater elastic force. The arc segment 414 enables the spring piece to maintain elastic deformation even under a large external force, preventing permanent deformation. The arc segment 414 can also optimize the stress distribution of the spring, making the stress distribution more uniform when the spring is subjected to external force, and further improving the fatigue resistance of the spring.

[0037] like Figure 2 and Figure 5 As shown, preferably, the upper end of the metal base 7 is fixed with a plurality of connecting posts 71, and the outer end 415 of the connecting piece 4 is detachably fixed to the upper end of the connecting posts 71 by screws.

[0038] like Figure 1 and Figure 2 As shown, the massage head 2 is, but is not limited to, a plastic product, which has a cover structure and also serves as an assembly shell. The upper end of the massage head 2 is provided with a mounting port 21 for mounting the vibrating head 1, and the lower end is an open end. The four corners of the lower end are provided with screw mounting holes 22 for fixing and connecting the mounting base 10.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the lower end of the vibrating head 1 is fixedly connected to the upper end of the connecting piece 4, and the upper end of the vibrating head 1 protrudes from the upper end of the mounting port 21. The vibrating head 1 is, but is not limited to, a plastic product. The upper end of the vibrating head 1 is the end face that abuts against the human body, including but not limited to an arc-shaped convex surface, and the lower end is provided with a threaded section 12 for fixing and connecting the connecting piece 4. Correspondingly, the middle part of the connecting piece 4 is provided with a screw hole 421 that mates with the threaded section 12. Compared to the upper end of the mounting port 21, the upper end of the vibrating head 1 protrudes by 2mm-5mm.

[0040] Preferably, the upper end of the vibrating head 1 protrudes about 2mm compared to the upper end of the mounting port 21.

[0041] Preferably, an O-ring 3 is also included, and the vibrating head 1 has an annular recess 11. After assembly, the inner side of the O-ring 3 is embedded in the annular recess 11, and the outer side is tightly attached to the inner wall of the mounting opening 21. The O-ring 3 is mainly used to solve the guidance problem, and at the same time to prevent the vibrating head 1 from contacting the massage head 2 and producing abnormal noise when vibrating.

[0042] like Figures 1-7 As shown, preferably, a vibration damping pad 9 is also included. After assembly, the vibration damping pad 9 is sandwiched between the metal base 7 and the mounting base 10 to reduce vibration from the metal base 7 to the mounting base 10 and the massage head 2.

[0043] like Figures 1-7 As shown, after assembly, the metal base 7 is fixedly connected to the mounting base 10, and a damping pad 9 is sandwiched between them. The outer end 415 of each spring piece 41 is fixedly connected to the corresponding connecting post 71. The upper end of the voice coil seat 5 is fixedly connected to the lower end of the connecting piece 4 by gluing or screws, and the lower end of the voice coil seat 5 is movably disposed inside the annular groove 708. A voice coil 6 is wound around the outside of the voice coil seat 5. The two ends of the voice coil 6 extend to the outside through the reserved holes of the metal base 7 and the mounting base 10 to connect to the external circuit. The length of the two ends of the voice coil 6 is reserved with a margin that allows the voice coil 6 to move up and down with the voice coil seat 5.

[0044] Because the upper end of the vibrating head 1 protrudes from the upper end of the mounting port 21, when the massage head 2 is in contact with the human body, the vibrating head 1 is in a compressed state (i.e., the spring piece 41 is in a downward elastic deformation), ensuring that the vibrating head 1 is always in contact with the human body. After the voice coil 6 is energized, the interaction between the electromagnetic field and the magnet will also cause the vibrating head 1 to move (i.e., the spring piece 41 will also undergo elastic deformation). The combined elastic deformation of the two forces ensures that the vibrating head 1 is always in contact with the human body, resulting in a stronger vibration and better comfort.

[0045] like Figures 1-9 As shown, the present invention also discloses a massage device, including a walking frame 100, a swing arm 200, a vibrating massage head 300, a massage wheel 400, and an audio circuit 500.

[0046] The walking frame 100 is movably equipped with two swing arms 200 and is equipped with a drive device and a microcontroller unit (MCU) to move the swing arms 200. These are conventional technologies for massage devices and will not be described in detail here.

[0047] like Figures 1-9 As shown, the massage device differs from existing massage devices in that:

[0048] One end of the swing arm 200 is fixed with a vibrating massage head 300 as described above, and the other end is provided with a massage roller 400. The two ends of the voice coil 6 of the vibrating massage head 300 are electrically connected to the output terminals of the audio circuit 500. In use, the audio signal output from the audio circuit energizes the voice coil 6 to generate electromagnetic fields. These electromagnetic fields interact with the magnetic field of the magnet block 8, causing the vibrating head 1 to move up and down.

[0049] Since the audio signal is a constantly changing electrical signal (a continuous analog signal), the electromagnetic field generated by energizing the voice coil 6 changes continuously, causing the amplitude and frequency of the massage head 300's up-and-down movement to change continuously with the audio signal.

[0050] In one specific embodiment, the audio circuit 500 includes an audio signal processing module and an audio power amplifier module, with the output of the audio signal processing module connected to the input of the audio power amplifier module. The audio signal processing module is primarily used for audio analysis and volume adjustment, while the audio power amplifier module is primarily used for low-frequency filtering and power amplification. These are conventional technologies and will not be elaborated further. The left and right channel audio signals of the audio power amplifier module are electrically connected to the left and right vibrating massage heads 300, respectively.

[0051] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
