Description

Technical Field

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

[0002] As people's quality of life improves, massage devices are gradually becoming common tools for health care and relaxation. For example, fascia guns, also known as deep myofascial impactors, are soft tissue rehabilitation tools that relax the body's soft tissues through high-frequency impacts.

[0003] As a modern fitness and rehabilitation tool, fascia guns are now being demanded by consumers in ways that go beyond basic massage functions. Consumers are increasingly focusing on the aesthetic design, comfort, and user experience of the products, with ergonomic design being crucial for both user experience and effectiveness.

[0004] Currently, most fascia guns on the market use a connecting rod and sleeve with bearings. Because the connection point is located at the very front of the first connecting rod, it causes a large angle of oscillation when the gun is moved, resulting in noise and affecting the user experience. At the same time, most fascia gun shells are T-shaped, which cannot adapt to the mechanical characteristics of different areas of the palm. When the user holds the gun, the pressure distribution is unbalanced because the force application area and the grip area have the same curvature. Prolonged use can easily cause muscle fatigue and affect the user experience. Utility Model Content

[0033] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0034] like Figures 1-3 As shown, this utility model provides a compact fascia gun, including a housing 1, a connecting rod 2, a massage head 13, an impact shaft 3, and a soft rubber part 4;

[0035] The housing 1 includes a first arc-shaped outer shell 101 and a second arc-shaped outer shell 102 that are symmetrically arranged and detachably fixedly connected, and a first through hole is provided on the housing 1;

[0036] Linkage 2 is located inside housing 1;

[0037] One end of the impact shaft 3 is detachably and fixedly connected to the massage head 13 (specifically, it can be a common fixing method such as snap-fit, so that people can replace the massage head 13 according to their needs), and the other end is located in the first through hole and is hinged to the connecting rod 2. The end of the first through hole facing the massage head 13 is set as the connecting end face 111.

[0038] The soft rubber part 4 is located at the hinge between the connecting rod 2 and the impact shaft 3;

[0039] The first arc-shaped outer shell 101 includes a first arc-shaped segment 1011 and a second arc-shaped segment 1012. The two ends of the first arc-shaped segment 1011 and the second arc-shaped segment 1012 are connected by smooth curve segments. The first arc-shaped segment 1011 is located below the connecting end face 111. The second arc-shaped segment 1012 has the same bending direction as the first arc-shaped segment 1011, and the bending arc is smaller than that of the first arc-shaped segment 1011.

[0040] By designing such an arc-shaped casing 1 to conform to ergonomics, it is possible to avoid the problem of uneven pressure distribution when holding the device, which can easily lead to muscle fatigue during prolonged use. At the same time, by setting up soft rubber parts 4, when the linkage 2 moves to pull the impact shaft 3 in reciprocating motion, the noise generated by the transmission can be greatly reduced, thereby achieving the purpose of noise reduction and greatly improving the user experience.

[0041] like Figure 2 As shown, the vertical distance from the bending apex of the first arc segment 1011 to the connecting end face 111 is 7.53mm-9.53mm, which is in line with the user's comfort in the grip area of ​​the fingers when using the fascia gun. More preferably, the vertical distance from the bending apex of the first arc segment 1011 to the connecting end face 111 is 8.2cm-8.8cm, which can make the user's grip posture more natural, so that the fingers can grip the fascia gun more firmly and reduce the possibility of slippage or displacement, especially when force needs to be applied or the grip position needs to be frequently adjusted.

[0042] like Figure 3 and Figure 6 As shown, it also includes a connecting shaft 5, a first mounting hole is provided at one end of the connecting rod 2 along its length direction, a second through hole is provided at the impact shaft 3 along its axial direction, one end of the connecting rod 2 extends into the second through hole, the connecting rod 2 does not contact the second through hole, the impact shaft 3 is provided with a second mounting hole along its axial direction, the connecting shaft 5 is located in the first mounting hole and the second mounting hole, and the soft rubber part 4 is located in the through hole and the first mounting hole, the soft rubber part 4 is in close contact with the inner wall of the through hole and is located on the periphery of the connecting shaft 5;

[0043] This design not only reduces noise but also reduces the length and volume of the entire drive mechanism by allowing the two parts of the connecting rod to extend into the through hole, making the fascia gun smaller and more convenient to carry.

[0044] like Figure 7 As shown, a first wear-resistant part 6 is provided between the soft rubber part 4 and the connecting shaft 5 (the first wear-resistant part 6 is a composite bushing, specifically a POM bushing or a Teflon bushing, which has excellent wear resistance). By providing the first wear-resistant part 6, direct contact and wear between the connecting shaft 5 and the soft rubber part 4 are avoided, thereby increasing the service life of the soft rubber part 4.

[0045] like Figure 8 As shown, the soft rubber part 4 includes a gasket 41 (a soft rubber gasket or a plastic gasket can be used here) and an O-ring 42. The top and bottom surfaces of the first wear-resistant part 6 are provided with gaskets 41. The gaskets 41 are in close contact with the inner wall of the through hole. The outer wall of the first wear-resistant part 6 is fitted with an O-ring 42. There is a gap between the first wear-resistant part 6 and the first mounting hole to ensure that the first wear-resistant part 6 and the connecting rod 2 will not come into contact. This not only reduces wear caused by friction, but also reduces noise generated by contact friction.

[0046] Soft rubber part 4 can also be used for, for example Figure 6 and Figure 7 The design is an I-shaped structure, but it uses a relatively large amount of soft rubber 4 material. By setting the soft rubber 4 in this way, noise reduction can be achieved while minimizing the amount of soft rubber 4 material used.

[0047] The soft rubber part 4 is made of rubber or silicone, which provides excellent cushioning and noise reduction.

[0048] like Figure 1 and Figure 2 As shown, the straight-line distance between the first arc-shaped outer shell 101 and the second arc-shaped outer shell 102 along their length direction is 89.5mm-92.5mm, and the arc distance along their length direction is 105mm-117mm. The straight-line distance from the bending vertex of the first arc segment 1011 to the bending vertex of the second arc segment 1012 is 50.3mm-52.3mm, and the arc distance from the bending vertex of the first arc segment 1011 to the bending vertex of the second arc segment 1012 is 73mm-75mm.

[0049] By designing a smaller fascia gun, its compact size offers significant portability advantages, making it easy for users to carry and use in various scenarios, such as travel, office, or outdoor activities. Its lightweight design also reduces the burden on users when holding it, improving comfort during long-term use. Furthermore, its compact appearance not only saves storage space but also makes the product more in line with modern minimalist aesthetics, satisfying users' dual needs for aesthetics and practicality.

[0050] Because the existing T-shaped design causes uneven force distribution between the palm's force application area and the grip area, resulting in excessive tension in local muscles, it is difficult to accommodate different hand shapes and distribute pressure across the entire palm surface. To improve this situation, this application designs an overall curved shell and considers the user's hand grip comfort. By having the second curved segment 1012 bend in the same direction as the first curved segment 1011, and with a curvature smaller than that of the first curved segment 1011, it not only solves the pressure imbalance and joint compensation damage problems of the traditional T-shaped structure, but also improves the user experience.

[0051] Furthermore, the inner side of the first arc-shaped outer shell 101 is provided with at least two threaded posts 20, and the second arc-shaped outer shell 102 is provided with positioning holes 1023 corresponding to the threaded posts 20. The threaded posts 20 pass through the corresponding positioning holes 1023 in sequence and are fixedly connected by screws. By providing threaded posts 20 on the inner side of the first arc-shaped outer shell 101 and engaging them with the positioning holes 1023 on the second arc-shaped outer shell 102, and connecting them with screws, not only is it ensured that the housing 1 will not loosen during use, enhancing the overall structural rigidity, but also the efficiency and precision of assembly are achieved, significantly improving the stability and rigidity of the structure. In addition, the combination of threaded post 20 and screw facilitates subsequent disassembly and maintenance, reduces maintenance costs, supports modular design, and further improves the overall performance and user experience of the product. The specific modular design includes the application of modular design in the fascia gun, covering parts such as the housing 1, drive motor 10, battery 14, massage components and circuit board 9. By designing the housing 1 with a detachable connection between the threaded post 20 and screw, partial parts can be replaced when the fascia gun components fail, improving maintenance convenience, enhancing product flexibility and scalability, reducing maintenance costs, and meeting users' customized needs.

[0052] like Figure 4 As shown, in order to enhance the aesthetic design of the product while satisfying the user's comfort, cover plates 19 are provided on the first arc-shaped outer shell 101 and the second arc-shaped outer shell 102 respectively. The two cover plates 19 are detachably and fixedly connected to the first arc-shaped outer shell 101 and the second arc-shaped outer shell 102 respectively.

[0053] Existing fascia gun housings generally rely on exposed screws for fixing. This method not only damages the overall aesthetic appearance of the product, but also causes discomfort to the human hand due to surface roughness. The design of the cover plate 19 in this application hides the screws used for fixing the first arc-shaped housing 101 and the second arc-shaped housing 102. The stable and reliable hidden screw assembly scheme not only optimizes the aesthetic appearance of the product, but also avoids the roughness of exposed connectors.

[0054] Furthermore, such as Figure 4 As shown, the two cover plates 19 are provided with at least two buckles 191 on the side facing the first arc-shaped outer shell 101 and the second arc-shaped outer shell 102. The outer sides of the first arc-shaped outer shell 101 and the second arc-shaped outer shell 102 are respectively provided with snap-fit ​​grooves 1022 that cooperate with the buckles 191. By providing buckles 191 on the inner wall of the cover plate 19 and cooperating with the snap-fit ​​grooves 1022 of the arc-shaped outer shell, the tight cooperation between the buckles 191 and the snap-fit ​​grooves 1022 can provide a reliable mechanical locking effect, ensuring that the cover plate 19 will not loosen or fall off during use. This not only improves the stability of the overall structure, but also enables quick disassembly and reinstallation, significantly improving the overall performance of the product and the user experience.

[0055] Furthermore, such as Figure 4 As shown, the surfaces of the first arc-shaped outer shell 101 and the second arc-shaped outer shell 102 are provided with grooves 1024. The shape of the grooves 1024 is adapted to the shape of the cover plate 19. Specifically, the grooves 1024 and the cover plate 19 are bean-shaped and similar to the shape of the casing 1, which is more aesthetically pleasing.

[0056] like Figure 5 As shown, at least one light hole 1021 is provided on the top surface of the first arc-shaped outer shell 101 and the second arc-shaped outer shell 102. A light guide column 7 is provided inside the light hole 1021. A light-shielding rubber block 8 is provided around the light guide column 7. There are two light-shielding rubber blocks 8. A circuit board 9 is provided inside the casing 1. An indicator light is provided on the circuit board 9. The light guide column 7 is located directly above the indicator light.

[0057] By setting two separate light-shielding rubber blocks 8, assembly is facilitated. Specifically, each light-shielding rubber block 8 is first assembled with a light guide post 7 to form an assembly. Then, one end of the light guide post 7 of the assembly is inserted into the light hole 1021. Finally, the first arc-shaped outer shell 101 and the second arc-shaped outer shell 102 are assembled. Compared with the existing method of directly using a single light-shielding rubber block 8, this avoids the trouble of having to bend the light-shielding rubber block 8 to make the remaining light guide post 7 obliquely inserted into the light hole 1021 of the second arc-shaped outer shell 102 or the first arc-shaped outer shell 101 when inserting part of the light guide post 7 into the light hole 1021 of the second arc-shaped outer shell 101 or the first arc-shaped outer shell 102 during the assembly of the first arc-shaped outer shell 101 and the second arc-shaped outer shell 102.

[0058] like Figure 1 and Figure 3 As shown, the top surface of the circuit board 9 is provided with a rubber part 15, and the top surface of the rubber part 15 is provided with a plastic button 16 (the plastic button 16 is used to control the start of the fascia gun for tapping massage; the specific control principle is existing technology and will not be described in detail here). The plastic button 16 passes through the top of the housing 1.

[0059] This design improves the feel of the buttons, provides cushioning with the rubber part 15, and prevents the plastic button 16 from directly contacting the circuit board 9, thus reducing wear on the circuit board 9 to some extent and also reducing noise. The plastic button 16 is located on the top of the housing 1 to fit the user's natural grip posture when using the fascia gun, ensuring that the thumb can easily reach and operate the button when using the fascia gun, making it convenient for the user, reducing the burden of operation, and improving efficiency and comfort.

[0060] like Figure 1 , Figure 2 and Figure 4As shown, it also includes a threaded cap 22 and two extension blocks 21. The extension blocks 21 are fixed to the first arc-shaped outer shell 101 and the second arc-shaped outer shell 102 near the massage head 13, respectively, and are fixedly connected to the first arc-shaped outer shell 101 and the second arc-shaped outer shell 102 by the threaded cap 22. The threaded cap 22 further locks the first arc-shaped outer shell 101 and the second arc-shaped outer shell 102, improving the firmness.

[0061] like Figure 3 As shown, it also includes a drive motor 10 and an eccentric wheel 11 located inside the housing 1. The output end of the drive motor 10 is connected to the eccentric wheel 11 to drive the eccentric wheel 11 to rotate. The eccentric shaft on the eccentric wheel 11 is connected to the connecting rod 2. A first damping rubber ring 12 is provided inside the housing 1. The drive motor 10 is fixedly connected to the first damping rubber ring 12.

[0062] By starting the drive motor 10, it drives the eccentric wheel 11 to rotate. The eccentric wheel 11 drives the connecting rod 2 to move. The connecting rod 2 drives the impact shaft 3 to reciprocate and extend. Finally, the impact shaft 3 drives the massage head 13 to perform a tapping massage. By setting the first damping rubber ring 12, the noise generated by the vibration of the drive motor 10 during operation can be reduced.

[0063] like Figure 3 As shown, the outer surface of the impact shaft 3 is provided with a second wear-resistant part 17 (made of the same material as the first wear-resistant part 6) and a second shock-absorbing rubber ring 18 in sequence. The impact shaft 3 is slidably connected to the second wear-resistant part 17, and the second shock-absorbing rubber ring 18 is in contact with the inner wall of the housing 1. By setting it in this way, the noise of the impact shaft 3 during reciprocating motion can be reduced, and the wear of the impact shaft 3 during reciprocating motion can also be reduced.

[0064] like Figure 3 As shown, a battery 14 is also provided inside the housing 1 to power the drive motor 10 and the circuit board 9.

[0065] The first arc-shaped outer shell 101, the second arc-shaped outer shell 102, and the cover plate 19 can be made of high-strength, wear-resistant materials. Among them, the high-strength, wear-resistant material can be ABS material, which can not only significantly improve the mechanical strength and impact resistance of the fascia gun and extend its service life, but also maintain the smoothness and integrity of the product appearance, reduce weight to improve grip comfort. At the same time, its excellent processing performance and chemical corrosion resistance help reduce production costs and ensure reliability in various environments. In addition, the recyclability of ABS material is in line with the concept of environmental protection, thus comprehensively optimizing the performance, aesthetics, production efficiency, and user experience of the fascia gun.

[0066] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
