Abstract
Description
Technical Field
[0001] This utility model relates to the field of massage devices, and in particular to a sonic vibration device for a massager and a vibration massager. Background Technology
[0002] Massage devices are instruments that generate specific mechanical or electrical stimulation through electrical signals and act on the human skin to achieve health benefits, therapeutic effects, and a sense of well-being. Existing massage devices use methods such as rotary motors, air pressure, and low-frequency current to generate stimulation, but these methods only apply pressure or stimulation to the body, resulting in less than ideal stimulation effects and unsatisfactory user experiences. For example, massage devices using rotary motors, which rely on the principle of generating vibration through varying centrifugal force, result in a small force acting perpendicularly on the skin surface, and the motors also generate considerable noise during operation. In recent years, a massage device utilizing the principle of a loudspeaker has emerged. This device generates sound wave vibrations by passing alternating current through a coil and interacting with a magnet. An elastic support maintains the sound wave vibrations in a vertical position and transmits the vibrations outward. The amplitude and frequency of the vibrations can be adjusted by setting the current and frequency, thus providing effective massage and stimulation to the human body. In massage devices using this principle, the shape and material of the elastic support significantly affect the massage effect. In existing technologies, elastic support components are basically made of metal materials. Metal materials have a long service life, but their excessive stiffness limits the transmission of vibration, causing the massage device to be unable to output a large amplitude. Alternatively, soft materials such as silicone are used. Soft materials have low rigidity and can transmit a large amplitude, but they are prone to aging under high-frequency vibration, resulting in a short service life of the elastic support component. Therefore, there is a need for an elastic support component solution that can balance amplitude and lifespan. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a vibration massager and its sonic vibration device.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A sonic vibration device for a massager includes a housing, an elastic support member, a mover, and a stator. The elastic support member supports the mover to reciprocate along a predetermined axis. The housing defines a receiving cavity for accommodating the mover, the stator, and the elastic support member. The elastic support member comprises:
[0006] Support portion, the moving element is engaged on the support portion; and
[0007] At least two elastic arms made of plastic, each elastic arm having two ends respectively engaged to the housing and the support;
[0008] The elastic arm is configured to extend between the housing and the support, and the length of the elastic arm is not less than 20 mm.
[0009] Furthermore, the two ends of the elastic arm are integrally joined to the housing and the support, respectively.
[0010] Furthermore, the housing includes an outer shell and a support frame, with the resilient arm integrally joined to the support frame.
[0011] Furthermore, the elastic arm is configured to extend in a curved manner between the support frame and the support portion to increase the length of the elastic arm.
[0012] Furthermore, the elastic arms are configured in groups of four.
[0013] Furthermore, the support frame is separately joined to the outer shell.
[0014] Furthermore, the support frame has a positioning plate extending toward the moving part, and the outer casing has a positioning groove that engages with the positioning plate.
[0015] Furthermore, the support frame has an annular wall surrounding the outside of the mover, and the outer shell has an annular groove that fits into the annular wall.
[0016] Furthermore, the housing includes a base and a top cover, the base being fixedly connected to a coil ring frame on which a stator coil is wound.
[0017] Furthermore, the top and bottom of the mover are covered with cushioning foam to absorb the kinetic energy of the mover colliding with the shell.
[0018] A vibrating massager having the aforementioned sonic vibration device.
[0019] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects:
[0020] By selecting plastic as the material for the elastic support and configuring the elastic arm to extend between the housing and the support, the elastic support has sufficient flexibility and appropriate stiffness to meet the requirements of the vibration device for large amplitude output. At the same time, it makes the elastic support less prone to aging or breakage under the high-frequency alternating force generated during vibration, thus ensuring the service life of the elastic support. In addition, plastic materials have a lower density than ordinary metals, which enables the elastic support to have a smaller mass and inertia, thereby improving the vibration performance of the vibration device.

[0032] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.
[0033] like Figure 1-6 As shown, the present invention provides a sonic vibration device for a massager, comprising a housing 1, an elastic support 2, a mover 3, and a stator 4. The elastic support 2 supports the mover 3 to reciprocate along a predetermined axis. In this embodiment, the elastic support 2 is arranged in the horizontal direction, and the mover 3 vibrates in the vertical direction. The housing 1 is hollow inside and forms a receiving cavity for accommodating the mover 3, the stator 4, and the elastic support 2.
[0034] The elastic support 2 includes a support portion 21, the shape of which is adapted to the mover 3, and the mover 3 is engaged with the support portion 21. The elastic support 2 also includes at least two elastic arms 22 made of plastic, with both ends of the elastic arms 22 respectively engaged with the housing 1 and the support portion 21. This allows the vibration of the mover 3 to be transmitted to the housing 1 via the support portion 21 and the elastic arms 22, and further transmitted to the outside, enabling the vibration device to perform its vibration function. The elastic arms are preferably made of PC / ABS material. ABS material has excellent rigidity and impact strength, and is easy to process, paint, and color, while PC / ABS combines the advantages of both ABS and PC materials, offering better mechanical properties and excellent rigidity, toughness, and impact strength. Using this material allows the elastic arms 22 to simultaneously possess sufficient elastic deformation capacity, good tolerance to high-frequency alternating forces generated by vibration, and stable support stiffness for the stator, meeting the requirements of a large amplitude output of the vibration device while also having a long service life. The elastic arm 22 is configured to extend between the housing 1 and the support 21. The elastic arm 22 suspends the support 21 and the mover 3 within a cavity inside the housing 1. When the mover 3 vibrates, the elastic arm 22 can be approximated as a cantilever beam model with the housing 1 as the fixed end. Therefore, the longer the elastic arm 22, the greater the range of motion of the support 21. Thus, the length of the elastic arm 22 is preferably not less than 20 mm, so that the mover 3 can vibrate with a larger amplitude, that is, the vibration device can output a stronger vibration.
[0035] like Figure 1-6 As shown, the connection between the elastic arm 22 and the housing 1 and the support 21 is preferably an integral joint to ensure the reliability of the connection. Further, the housing 1 includes outer shells 11 and 12 and a support frame 23, with the elastic arm 22 integrally joined to the support frame 23. Preferably, the elastic arm 22 is configured to extend curvedly between the support frame and the support portion. In this embodiment, the elastic arm 22 extends in an arc shape to increase its length and optimize its elastic deformation characteristics. However, the extension method of the elastic arm 22 is not limited to this.
[0036] In this embodiment, four elastic arms 22 are configured. These elastic arms 22 are preferably arranged symmetrically around the support portion 21, and are evenly distributed around the support portion 21 at the engagement position, thereby providing good support for the support portion 21. Depending on the actual needs of the vibration device, more elastic arms 22 can be provided at any suitable location within the cavity of the housing 1.
[0037] like Figure 1-6As shown, the support frame 23 and the outer shells 11 and 12 are preferably connected in a split manner. The advantage of this split connection is that it is easy to disassemble and assemble, but the disadvantage is that the connection is relatively loose, which may affect the transmission of vibration. Therefore, a structure is needed to reinforce the connection between the support frame and the outer shell. Specifically, the support frame 22 has a positioning plate 16 extending toward the moving part, and the outer shells 11 and 12 have positioning grooves 12. The positioning plate 16 is embedded in the positioning grooves 12. In this embodiment, the positioning plate 16 and the positioning grooves 12 are preferably arranged in two sets around the support part 21 to make the connection more reliable. At the same time, the support frame 23 has an annular wall 15 surrounding the outside of the moving part 3, and the outer shells 11 and 12 have annular grooves 14. The annular wall 15 is embedded in the annular grooves 14, which, together with the positioning plate and the positioning grooves, ensure that the vibration of the moving part 3 can be transmitted to the shell 1. The support frame 23 can be configured with its shape according to the needs of the vibration device, and the shape of the annular groove 14 can also be changed accordingly. The support frame 23 and the outer shells 11 and 12 can also be integrally formed. If integrally formed, the support frame and the outer shell are already fixedly connected, and the positioning plate and positioning groove can be omitted.
[0038] like Figure 1-6 As shown, as a preferred embodiment, the outer casing 1 includes a base 12 and a top cover 11. A coil ring frame 41 is fixedly connected to the base 12. A stator coil 42 is wound on the coil ring frame 41. Meanwhile, the moving part 3 is provided with an annular cavity 33 for accommodating the stator coil 42. The stator coil 42 is inserted into the annular cavity 33, so that the stator coil 42 can perform electromagnetic induction with the moving part 3 to generate vibration.
[0039] When the mover 3 vibrates, if the amplitude is large, the mover 3 may collide with the shell 1, which may affect the vibration effect or even damage the vibration device. Therefore, the top and bottom of the mover 3 are covered with cushioning foam 31 and 32 to absorb the kinetic energy of the collision between the mover 3 and the shell 1, thus playing a cushioning role. The cushioning foam 31 and 32 can preferably be made of EVA foam. EVA foam has good softness, resilience and tensile strength, and strong toughness, and has good shock absorption and cushioning performance; in addition, it is also environmentally friendly and has sound insulation properties, which can further improve the overall performance of the vibration device.
[0040] The sonic vibration device provided by this utility model is used in a massager. For example, the vibration device is installed on a massage head made of silicone, plastic or other materials, and the vibration generated by the vibration device is transmitted to the human body through the massage head to massage the skin, scalp or hands and feet.
[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
