Description

[0002] A fascia gun, also known as a deep myofascial percussion device, is a portable soft tissue rehabilitation tool that acts on the human fascia through high-frequency vibration and impact to achieve the effects of relaxing muscles, relieving pain, and promoting blood circulation. Most of the common fascia guns on the market currently adopt an eccentric motor drive method, where the eccentric motor drives the entire body to vibrate through the centrifugal force of the eccentric wheel, thereby realizing the vibration of the fascia gun head.

[0003] However, the eccentric motor also has some limitations. For example, the motor vibration is single and fixed-point vibration. The drive method of the eccentric motor causes the vibration intensity in different directions to be inconsistent. When the vibration intensity is weak, it cannot achieve a good massage effect.

[0040] Reference Figures 1-8, this embodiment provides a sonic oscillator somatic fascia gun, which includes a fascia gun main body 1 and a fascia gun head 2; the fascia gun main body 1 includes a first housing 11, a vibration device 3 and a power amplifier control board installed in the first housing 11; the vibration device 3 includes a second housing 31, an audio resonator 32 and a magnetic component 33 installed in the second housing 31; the audio resonator 32 is respectively connected to the magnetic component 33 and the power amplifier control board; the first housing 11 is provided with a gun head connection bracket 12, and the gun head connection bracket 12 is connected to the fascia gun head 2; the audio resonator 32 includes a voice coil 321 and a resonance member 322, the voice coil 321 is connected to the second housing 31, and the front end of the second housing 31 is connected to the gun head connection bracket 12 through a drive shaft 34; the resonance member 322 is arranged at a position close to the rear end in the housing, and the magnetic component 33 is arranged between the voice coil 321 and the resonance member 322; the resonance member 322 includes two groups of elastic sheet components 3221, and each group of elastic sheet components 3221 includes a first fixing ring 3222, a second fixing ring 3223 and a plurality of elastic sheets 3224 distributed circumferentially (such as Figure 8 ).); the elastic sheet 3224 is a three-dimensional anisotropic structure, and both ends of the elastic sheet 3224 are respectively connected to the first fixing ring 3222 and the second fixing ring 3223; the two first fixing rings 3222 of the two groups of elastic sheet components 3221 are connected to each other (such as Figure 7 ); one of the second fixing rings 3223 of the two groups of elastic sheet components 3221 is connected to the housing, and the other second fixing ring 3223 is connected to the magnetic component 33; the elastic sheets 3224 of the two groups of elastic sheet components 3221 are distributed circumferentially in a staggered manner and are symmetrically arranged in the radial direction.

[0041] Driven by the sonic oscillator power amplifier control board and configured with highly elastic elastic sheets 3224 of three-dimensional anisotropic structure, the all-round transmission of sonic somatic vibration is realized. The frequency debugging compatibility of the power amplifier control board is higher, and the vibration feeling is stronger.

[0042] In this embodiment, the elastic sheet 3224 is of an S-shaped or wavy structure (such as Figures 7-8 ), with a larger elastic stroke, stronger elastic force and pulling force, an increased vibration stroke, an increased amplitude, a stronger vibration feeling, and at the same time, the sonic somatic noise is smaller. The material of the elastic sheet 3224 is plastic material, metal material or composite organic material, which can be selected according to different requirements.

[0043] In this embodiment, the elastic piece 3224 and the first fixing ring 3222 and the second fixing ring 3223 are integrally or separately provided, with a longer service life. By symmetrically arranging the elastic pieces 3224 of the two sets of elastic piece assemblies 3221, with one set connected to the housing and one set connected to the magnetic component 33, when vibration occurs, two stroke routes in opposite directions are formed, increasing the vibration stroke, and the amplitude and intensity of the three-dimensional structure vibration will be very large. The vibrating elastic piece 3224 assists in increasing the vibration stroke, and the two sets of elastic pieces 3224 (such as Figure 6 ) distributed with circumferential dislocation have a more uniform lengthened stroke, realizing all-round vibration transmission, and the vibration intensity in different directions is consistent, improving the massage effect.

[0044] In this embodiment, the magnetic component 33 includes a U-shaped iron 331, a first magnet 332, a second magnet 333, and a magnetic conduction sheet 334 (such as Figure 5 ). The U-shaped iron 331 has an installation cavity 3311 with a U-shaped cross-section and an open shape; the opening of the installation cavity 3311 faces the voice coil 321; the first magnet 332, the magnetic conduction sheet 334, and the second magnet 333 are sequentially installed inward from the opening, and there is a gap 3312 between them and the inner wall of the installation cavity 3311. Part of the voice coil 321 is placed in the gap 3312, and this gap 3312 serves as a voice gap to provide space for the vibration of the voice coil 321.

[0045] When an alternating current is passed through the voice coil 321, the magnetic field generated by it interacts with the magnetic field of the magnet, causing the voice coil 321 to vibrate back and forth in the magnetic field. This vibration is transmitted to the fascia gun head 2 through the second housing 31 and the gun head connection bracket 12, thereby realizing high-frequency vibration and achieving the massage effect. The U-shaped iron 331, the first magnet 332, and the second magnet 333 mainly play the role of providing a stable magnetic field, and the role of the magnetic conduction sheet 334 is to guide and enhance the magnetic field and improve the vibration efficiency.

[0046] The U-shaped iron 331, the first magnet 332, and the second magnet 333 use a magnetic component 33 combined with neodymium iron boron and ferrite, with stronger magnetism, improving the vibration efficiency and intensity. Through the power amplifier control board for frequency debugging according to different requirements, the vibration frequency can be customized, and the effective frequency of the sound wave can be adjusted within the range of 20 Hz - 20 kHz, providing different physical feeling states or modes, with stronger compatibility.

The ball pulley assembly 15 is a mechanical component, which can make the vibration smoother, with less resistance, less power consumption, and stronger vibration feeling.

[0050] The rear end of the gun head connection bracket 12 is connected to the drive shaft 34 through a fixing screw 122. The rear end of the drive shaft 34 passes through the second housing 31 and is sequentially connected to the second magnet 333 and the magnetic conduction sheet 334.

The U-shaped iron 331, as a U-shaped structure, plays a role in conducting magnetism. The first fixing part and the second fixing part are provided to make the installation of the shrapnel 3224 simpler, facilitating assembly and maintenance.
