Description

Technical Field

[0001] This utility model relates to the field of fascia gun technology, and specifically to a fascia gun. Background Technology

[0002] With the improvement of people's quality of life, massage devices such as fascia guns (deep myofascial impactors) have gradually become important tools for public health and relaxation. As a soft tissue rehabilitation device, a fascia gun uses a high-speed motor to drive its "gun head" to generate high-frequency vibrations, which act on the skin, fat, fascia, and muscle layers, effectively reducing local tissue tension, relieving pain, and promoting blood circulation. Existing fascia guns on the market mainly employ a specific transmission mechanism: an eccentricity is formed by a certain distance between the motor shaft and the eccentric wheel shaft. When the motor rotates, it drives the eccentric wheel to perform circular motion. Due to the presence of the eccentric wheel, the connecting rod reciprocates accordingly, thereby achieving impact relaxation of the body's soft tissues.

[0003] However, this traditional design has several shortcomings. First, in terms of the connection structure, the use of a connecting rod and sleeve with bearings, and the connection point being located at the very front of the first connecting rod, easily leads to large-angle swinging during actual operation, resulting in noise. Second, most fascia guns on the market currently use I-shaped shock-absorbing pads and screws to fix the motor bracket. This method requires at least three shock-absorbing pads to ensure assembly flatness, which not only increases the number of parts and assembly complexity, but also places higher demands on the housing space due to the inconvenience of axial screw fixing, which is not conducive to the miniaturization design of the product. Summary of the Invention

[0004] The purpose of this invention is to provide a fascia gun that solves the problems of noise generation and complex assembly in existing fascia gun designs.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A fascia gun is provided, including a bottom cover, a middle cover inside the bottom cover, a top cover on the bottom cover, a drive assembly inside the bottom cover on the right side, a lithium battery inside the bottom cover on the left side of the drive assembly, the drive assembly being electrically connected to the lithium battery, an eccentric block behind the drive assembly, a connecting rod assembly on the eccentric block, a first piston inside the bottom cover on the left side, the first piston being located behind the lithium battery, a second piston slidingly disposed inside the first piston, a piston core at the left end of the connecting rod assembly, a pin between the piston core and the second piston, a piston damping rubber ring outside the first piston, a massage head snapped onto the left side of the second piston, and a drive core behind the bottom cover, the drive core being electrically connected to the drive assembly to control the eccentric block to drive the connecting rod assembly to reciprocate, thereby driving the piston core to drive the second piston to reciprocate within the first piston, and thus driving the massage head to reciprocate.

[0007] As a preferred embodiment of a fascia gun, the bottom cover and the rear side of the top cover are provided with buttons and light-emitting elements, the buttons are located to the left of the light-emitting elements and are electrically connected to the drive core.

[0008] As a preferred embodiment of a fascia gun, an upper decorative element is provided on the rear side of the bottom cover and the front cover, and the upper decorative element is located outside the button and the light-emitting element.

[0009] As a preferred embodiment of a fascia gun, the bottom cover and the front cover are provided with a lower trim and a lanyard hole, with the lower trim located to the left of the lanyard hole.

[0010] As a preferred embodiment of a fascia gun, a gun head trim is provided on the left side of the bottom cover and the top cover, and the gun head trim is located outside the second piston.

[0011] As a preferred embodiment of a fascia gun, the driving assembly includes a motor mounting base disposed on the right side inside the bottom cover, a drive motor mounted on the motor mounting base, a motor shock-absorbing rubber ring disposed between the motor mounting base and the bottom cover, and the drive motor being connected to the lithium battery and the drive battery respectively.

[0012] As a preferred embodiment of a fascia gun, the linkage assembly includes a drive linkage disposed on the piston core, and a bearing is disposed inside the right side of the drive linkage, wherein the bearing axis and the eccentric block axis are not located on the same central axis.

[0013] As a preferred embodiment of a fascia gun, the massage heads are provided in multiple ways, and the multiple massage heads can be interchanged to adapt to different massage areas.

[0014] The beneficial effects of this utility model are as follows: This design effectively solves the problem of mechanical vibration and operating noise caused by the sleeve fit clearance by adopting a piston structure instead of the multi-sleeve structure in the traditional solution, which significantly improves the smoothness and quietness of operation. At the same time, axial positioning is achieved by the bottom cover and the middle cover, and lateral fixation is achieved by the motor mounting base, forming a stable installation structure with multi-directional constraints. This reduces the dependence on adjustment elements such as adjusting pads, which not only reduces the assembly complexity and production cost, but also optimizes the internal space layout, providing favorable conditions for the miniaturization and compact design of the product.

[0025] like Figure 1-3As shown, this utility model provides a technical solution: a fascia gun, including a bottom cover 1, a middle cover 2 installed inside the bottom cover 1 by four M2*8 screws, a face cover 3 snapped onto the bottom cover 1, a drive assembly 4 installed on the right side inside the bottom cover 1, a lithium battery 5 installed on the left side inside the drive assembly 4, the drive assembly 4 and the lithium battery 5 being electrically connected, an eccentric block 6 installed on the rear side of the drive assembly 4, an M2*15 screw installed on the eccentric block 6 to lock the eccentric block 6 onto the drive assembly 4, a connecting rod assembly 7 installed on the eccentric block 6, a first piston 8 installed on the left side inside the bottom cover 1, the first piston 8 being located behind the lithium battery 5, a second piston 9 slidably installed inside the first piston 8, a piston core 10 installed at the left end of the connecting rod assembly 7, a pin 11 installed between the piston core 10 and the second piston 9 to fix the piston core 10 and the second piston 9, and the connecting rod assembly 7 is secured to the pin 11. The upward rotation allows for easy replacement of the piston core 10 and pin 11 after wear, reducing operating costs. A piston damping ring 12 is installed on the outside of the first piston 8 to reduce noise generated by the reciprocating motion of the second piston 9 during massage. A massage head 13 is snapped onto the left side of the second piston 9. The massage head 13 has multiple different shapes and can be interchanged to suit different massage areas. A drive core 14 is installed on the rear side of the bottom cover 1. By fixing the drive assembly 4, lithium battery 5, eccentric block 6, connecting rod assembly 7, first piston 8, second piston 9, and piston core 10 inside the bottom cover 1 and middle cover 2, multiple internal components are fixed, and the top cover 3 is used to reduce noise transmission. The drive core 14 is electrically connected to the drive assembly 4 to control the eccentric block 6 to drive the connecting rod assembly 7 to reciprocate, which in turn drives the piston core 10 to drive the second piston 9 to reciprocate within the first piston 8, thereby driving the massage head 13 to reciprocate.

[0026] like Figure 2 As shown, a button 15 and a light-emitting element 16 are installed on the rear side of the bottom cover 1 and the front cover 3. The button 15 is located to the left of the light-emitting element 16 and is electrically connected to the drive core 14 to control and adjust the rotation speed of the drive assembly 4 and display the lighting effect. An upper decorative element 17 is also installed on the rear side of the bottom cover 1 and the front cover 3. The charging interface of the lithium battery 5 protrudes from the upper decorative element 17. The upper decorative element 17 is located outside the button 15 and the light-emitting element 16. A lower decorative element 18 is installed on the front side of the bottom cover 1 and the front cover 3. A lanyard hole is opened on the right side of the bottom cover 1 and the front cover 3. The lanyard hole facilitates the installation of a hanging rope to improve portability. The lower decorative element 18 is located to the left of the lanyard hole. A gun head decorative element 19 is installed on the left side of the bottom cover 1 and the front cover 3. The gun head decorative element 19 is located outside the second piston 9. The upper decorative element 17, the lower decorative element 18, and the gun head decorative element 19 are used to decorate the appearance of the product and improve its overall aesthetics.

[0027] like Figure 3 As shown, the drive assembly 4 includes a motor mounting base 41 located on the right side inside the bottom cover 1. A drive motor 42 is horizontally fixed to the motor mounting base 41 by three M4*5 screws. An eccentric block 6 is mounted on the output shaft of the drive motor 42. The drive motor 42 is electrically connected to the lithium battery 5 and the drive core 14. A motor damping rubber ring 43 is installed between the motor mounting base 41 and the bottom cover 1. The motor damping rubber ring 43, together with the three horizontally mounted M4*5 screws, plays a role in damping vibration and reducing noise. It also simplifies the original method of using I-shaped damping rubber pads and screws inserted at the four corners to fix the motor bracket, thereby simplifying the assembly process and saving space.

[0028] like Figure 3 As shown, the connecting rod assembly 7 includes a drive connecting rod 71 mounted on the piston inner core 10. The left side of the drive connecting rod 71 is rotatably connected to the pin 11. A connecting rod damping rubber ring is provided on both sides of the drive connecting rod 71 between it and the piston inner core 10 to reduce the noise generated by the reciprocating motion of the drive connecting rod 71. A bearing 72 is installed inside the right side of the drive connecting rod 71. The axis of the bearing 72 is not located on the same central axis as the axis of the eccentric block 6. Two M2*4 type screws are symmetrically mounted on the rear side of the drive connecting rod 71 to support the bearing. The bearing 72 is further limited by two M2*4 screws symmetrically installed on the rear side of the eccentric block 6. This prevents the bearing 72 from shifting due to prolonged operation of the drive motor 42. The rotation of the drive motor 42 drives the eccentric block 6 to rotate, which in turn drives the bearing 72 to rotate circumferentially. The circumferential rotation of the bearing 72 drives the drive linkage 71 to reciprocate, which in turn drives the massage head 13 to reciprocate and generate high-frequency vibrations. These vibrations act on the skin, fat, fascia, and muscle layers, effectively reducing local tissue tension, relieving pain, and promoting blood circulation.

[0029] Working principle: During use, according to the massage needs, the corresponding massage head 13 is engaged on the left side of the second piston 9. Pressing the button 15 controls the drive core 14 to start the drive motor 42, and the brightness of the light-emitting element 16 indicates the working level of the drive motor 42. The rotation of the drive motor 42 drives the eccentric block 6 to rotate. The rotation of the eccentric block 6 drives the drive connecting rod 71 to reciprocate through the bearing 72. The drive connecting rod 71 drives the piston core 10 and the second piston 9 to reciprocate within the first piston 8 through the pin 11, which in turn drives the massage head 13 at the end of the second piston 9 to reciprocate. When the light-emitting element 16 indicates that the battery is about to run out, it can be charged through the charging port of the lithium battery 5 at the upper trim 17.

[0030] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
