Description

Technical Field

[0001] This utility model relates to the field of massage devices, and more particularly to a sonic vibration device and a vibration massage device for human stimulation. 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 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 motor generates 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. Support springs maintain the sound wave vibrations vertically and transmit them externally. The amplitude and frequency of the vibrations can be adjusted by setting the current and frequency, thus providing effective massage and stimulation to the body. In massage devices using this principle, the shape and material of the support springs significantly affect the massage effect. In existing technologies, support springs are mostly 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 shorter service life of the support spring. Therefore, a support spring solution that can balance amplitude and lifespan is needed. 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 sound wave vibration device for human stimulation.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A sonic vibration device for human stimulation includes a housing, a support spring, a mover, and a stator. The support spring supports the mover to reciprocate along a predetermined axis. The housing defines a receiving cavity for accommodating the mover, the stator, and the support spring. The support spring sheet includes: an inner edge portion fixed to the mover; an outer edge portion fixed to the housing or stator; and a spring wave portion having at least one annular corrugation for enhancing elastic deformation capability, the spring wave portion being disposed between the inner edge portion and the outer edge portion; wherein the support spring sheet is formed by impregnating a spring wave sheet with the annular corrugation pressed on with glue.

[0005] Furthermore, the support spring is a support spring made of para-aramid fiber.

[0006] Furthermore, the elastic wave portion has an elastic groove that is recessed in the first direction, and the elastic groove is configured as an annular wave with an arc-shaped cross section.

[0007] Furthermore, a shaped groove is connected to both the inner and outer edges of the elastic groove. The shaped groove is configured to be recessed in a second direction opposite to the first direction, and the depth of the shaped groove is less than that of the elastic groove.

[0008] Furthermore, the depth of the elastic groove relative to the outer edge ranges from 1.0 to 3.0 mm.

[0009] Furthermore, the depth of the shaping groove relative to the outer edge ranges from 0.5 to 1.5 mm.

[0010] Furthermore, the housing includes a base and a top cover, the base having a support edge adapted to the outer edge, the outer edge being clamped and fixed between the support edge and the top cover.

[0011] Furthermore, the upper cover is provided with a plurality of vent holes arranged circumferentially.

[0012] Furthermore, the base and the top cover form a joint in the middle of the housing, and both the base and the top cover have an arc-shaped surface that gradually tapers from the joint, so that the housing as a whole presents a flying saucer shape.

[0013] Furthermore, a fixing ring is installed on the moving part, and the inner edge is clamped and fixed between a positioning step formed on the moving part and the fixing ring.

[0014] Furthermore, the inner edge is infused with adhesive in the clamped state.

[0015] Furthermore, the base is fixedly connected to a coil ring frame and a PCB board, and the stator coil is wound on the coil ring frame and electrically connected to the PCB board.

[0016] A vibration massage device includes a sonic vibration device configured as described above for use in stimulating the human body.

[0017] Due to the adoption of the above technical solutions, this utility model has the following beneficial effects: 1. By selecting para-aramid as the material for the support spring, pressing the support spring into annular corrugations to improve its elastic deformation capacity, and simultaneously impregnating the support spring with resin to shape it, the support spring possesses sufficient flexibility and appropriate stiffness to meet the requirements of the vibration device's large amplitude output. Furthermore, aramid material has high strength, high toughness, and high tear resistance, making the support spring less prone to aging or breakage under the high-frequency alternating forces generated during vibration, thus ensuring the service life of the support spring and the vibration device. In addition, aramid has a lower density than most metals, enabling the support spring to have a smaller mass and inertia, thereby improving the vibration performance of the vibration device.

[0024] 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.

[0025] like Figure 1-6 As shown, the sonic vibration device applied to human stimulation includes a housing 100, a support spring 200, a mover 300, and a stator 400. The support spring 200 supports the mover 300 to reciprocate along a predetermined axis. In this embodiment, the support spring 200 is arranged horizontally, and the mover 300 vibrates vertically. The housing 100 is hollow inside and forms a receiving cavity 130 for accommodating the mover 300, the stator 400, and the support spring 200.

[0026] The support spring 200 has an inner edge 210 and an outer edge 220. The inner edge 210 is fixed to the mover 300, and the outer edge 220 is fixed to the housing 100 or the stator 400. This allows the vibration of the mover 300 to be transmitted to the housing 100 via the support spring 200 and further to the outside, enabling the vibration device to perform its vibration function. To meet the requirement of a large amplitude output from the vibration device, the support spring 200 should have sufficient elastic deformation capacity. Therefore, the support spring 200 has a wave portion 230, which has at least one annular corrugation to enhance the elastic deformation capacity. The wave portion 230 is disposed between the inner edge 210 and the outer edge 220. This structure allows the support spring 200 to function almost like a spring when the mover 300 vibrates, ensuring that the vibration of the mover 300 is effectively transmitted to the outside, and enabling the vibration device to output a large amplitude. The support spring sheet 200 is formed by impregnating a spring sheet with annular corrugations with resin. In the impregnation process, it is preferable to use fiber impregnated with phenolic resin for shaping. The spring sheet treated with this phenolic resin has the characteristics of good preservation and high strength.

[0027] Because the support spring 200 is continuously subjected to high-frequency alternating forces during the operation of the vibration device, and aramid material has the characteristics of high strength and high tear resistance, it is suitable for the working environment of the support spring 200. Using para-aramid material in the support spring 200 ensures that it is not prone to aging or breakage under the action of high-frequency alternating forces, thus guaranteeing the service life of the vibration device. At the same time, aramid has a density much lower than that of ordinary metals (1.45 g / cm³). 3 This reduces the mass and inertia of the support spring 200, thereby improving the performance of the vibration device. Furthermore, aramid materials include para-aramid, meta-aramid, and their corresponding polymers; in this embodiment, the support spring 200 is made of aramid material.

[0028] like Figure 2-5 As shown, as a preferred embodiment, the spring section 230 has an elastic groove 231 recessed in the first direction, and the elastic groove 231 is constructed as an annular corrugation with an arc-shaped cross-section. Compared with other cross-sectional shapes such as sawtooth, the arc-shaped cross-section is more conducive to improving the elastic deformation capability of the support spring 200. In this embodiment, the first direction is preferably configured to be vertically upward. According to the actual functional needs of the vibration device, more annular corrugations can be configured in the spring section 230, and the size of the support spring 200 can be adjusted to change the elastic deformation characteristics of the support spring 200, thereby meeting the requirements of various types of vibration output.

[0029] Both the inner and outer edges of the elastic groove 231 are connected to a shaped groove 232. The shaped groove 232 is configured to be recessed in a second direction opposite to the first direction (i.e., downward along the vertical direction), and preferably is constructed to be an arc shape similar to the elastic groove 231 and smoothly connected to the elastic groove 231, so as to connect the elastic part 230 and the inner edge part 210 (or the outer edge part 220), and optimize the elastic deformation characteristics of the supporting elastic piece 200. In this embodiment, the outer edge part 220 is used as a reference (e.g., Figure 3 (As shown by the dashed line), the depth d2 of the shaping groove 232 is less than the depth d1 of the elastic groove 231. Further, the depth d1 of the elastic groove 231 relative to the outer edge ranges from 1.0 to 3.0 mm, and the depth of the shaping groove 232 relative to the outer edge 220 ranges from 0.5 to 1.5 mm. It should be understood that, provided the depth d2 of the shaping groove 232 is less than the depth d1 of the elastic groove 231, the dimensions of the elastic groove 231 and the shaping groove 232 are not limited to this and can be adjusted according to the vibration output requirements of the vibration device.

[0030] like Figure 1 and Figure 2 As shown, the housing 100 includes a base 120 and a top cover 110, which are preferably detachably connected. The internal space after they are fastened together forms the receiving cavity 130. The base 120 has a support edge 130, which is annular and its dimensions are adapted to the outer edge 220. Furthermore, the outer edge 220 is clamped and fixed between the support edge 130 and the top cover 110, so that vibration can be transmitted to the housing 100 by the support spring 200, and then transmitted to the outside to stimulate the human body.

[0031] When the vibration device is working, the temperature of the receiving cavity 130 will rise due to the current flowing through the coils on the stator 400. Therefore, the upper cover 110 is provided with a plurality of circumferentially arranged vent holes 111, allowing the receiving cavity 130 to ventilate and dissipate heat from the outside. In this embodiment, the base and the upper cover form a joint 140 in the middle of the housing 100, and both the base and the upper cover have arc-shaped surfaces that gradually taper from the joint 140, so that the housing 100 as a whole presents a saucer shape.

[0032] like Figure 1 , Figure 4-6As shown, the mover 300 includes a magnet 320 and a mover body 301. The mover body 301 has a cavity 330 for accommodating the magnet 320. The magnet 320 can interact with the stator 400, allowing the mover 300 to vibrate under the action of electromagnetic force. Preferably, the mover 300 is equipped with a fixing ring 310 for fixing the support spring 200. The fixing ring 310 can be made of rubber. The mover body 301 of the mover 300 has a positioning step 302. The size of the fixing ring 310 is adapted to the positioning step 302, so that the inner edge 210 is clamped and fixed between the positioning step 302 and the fixing ring 310. Preferably, the inner edge 210 is filled with adhesive when clamped, thereby increasing the reliability of the connection between the support spring 200 and the mover 300 and preventing the support spring 200 from loosening from the mover 300 due to vibration stress.

[0033] like Figure 1 and Figure 2 As shown, a coil ring frame 410 and a PCB board 500 are fixedly connected to the base 120. The stator coil 420 is wound on the coil ring frame 410 and electrically connected to the PCB board 500. Furthermore, the PCB board 500 is electrically connected to an external power source, enabling the stator coil 420 to be energized to drive the rotor 300. Preferably, a control circuit can be provided on the PCB board to control the magnitude and frequency of the current input to the stator coil 420, thereby obtaining vibration outputs of different frequencies and amplitudes. In addition, the PCB can be placed at any suitable position within the housing 100.

[0034] The sonic vibration device provided in this embodiment is used in a vibration massage device with a sonic vibration device. For example, the vibration device is installed on a massage head made of silicone material, plastic material, etc., 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.

[0035] 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.
