Description

Technical Field

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

[0002] A fascia gun, also known as a deep myofascial release device, is a portable soft tissue rehabilitation tool consisting of a high-speed motor and a gun head. Its main function is to activate and relax muscles and relieve pain. Common fascia guns include single-head and double-head models, which have one and two massage heads respectively. In double-headed fascia guns, the two massage heads are positioned close together at the same end of the handle. Furthermore, in existing fascia guns, whether single-headed or double-headed, the movement direction of the massage heads is perpendicular to the handle. This restricts the user's grip on the handle, limiting the direction of massage head movement and reducing flexibility.

[0003] The drive mechanism of a fascia gun is usually located inside the handle. In order to drive the massage head to reciprocate in a direction perpendicular to the handle axis, the drive mechanism needs to work with components such as eccentric wheels and eccentric shafts to change the transmission direction, making the components and installation of the drive mechanism quite complicated.

Detailed Implementation

[0037] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0038] refer to Figure 1 and Figure 7 The fascia gun of this invention includes a handle 10, at least one set of massage head assemblies 20, and a drive system. At least one set of massage head assemblies 20 is disposed at the end of the handle 10 and can reciprocate relative to the handle 10 in the axial direction. The drive system includes a first drive mechanism 30, which is disposed within the handle 10 and whose transmission direction is coaxial with the handle 10. The first drive mechanism 30 is connected to the massage head assemblies 20 and drives the massage head assemblies 20 to reciprocate in the axial direction of the handle 10.

[0039] When using the device, the user can hold the handle 10 from any direction, align the end massage head assembly 20 with the area to be massaged, and then turn it on to perform an impact massage on the area to be massaged.

[0040] like Figures 1-3 As shown, a fascia gun according to an embodiment of the present invention includes a handle 10, two sets of massage head assemblies 20, and a drive system. The two sets of massage head assemblies 20 are movably fitted at opposite ends of the handle 10. Corresponding to the two sets of massage head assemblies 20, the drive system includes two sets of first drive mechanisms 30, which are arranged within the handle 10 corresponding to the two sets of massage head assemblies 20. Each set of first drive mechanisms 30 is connected to the corresponding massage head assembly 20, driving the massage head assembly 20 to reciprocate axially in the handle 10.

[0041] The arrangement of two sets of massage head assemblies 20 makes the fascia gun in this embodiment a double-headed fascia gun.

[0042] The handle 10 can be a cylindrical structure. For ease of gripping, the handle 10 is cylindrical. The handle 10 further includes a housing 11, which is a cylindrical structure open at both ends. The inner cavity of the housing 11 is used to house part of the first drive mechanism 30 and the massage head assembly 20. The open ends of the housing 11 form openings, and the massage head assembly 20 fits into these openings and passes through them into the housing 11 to connect with the first drive mechanism 30.

[0043] To facilitate the assembly of the first drive mechanism 30, the housing 11 is preferably configured as a separate unit. For example... Figure 3 In the illustrated embodiment, the housing 11 includes two half-shells 110, which together form a cylindrical structure. The mating sides of the two half-shells 110 can be mated using at least one of the following methods: snap-fit, post-hole fit, and step fit.

[0044] A soft padding layer 12 may also be provided on the outer surface of the housing 11 to improve the feel, enhance grip comfort, and also serve as an anti-slip layer. The soft padding layer 12 may be made of materials such as silicone. The soft padding layer 12 may preferably be located at the gripping position on the housing 11, or it may extend to other positions, or it may be provided on the entire surface of the housing 11, and can be flexibly set as needed.

[0045] like Figure 2 and Figure 3 As shown, the massage head assembly 20 may further include a piston 21, a massage head 22 disposed at one end of the piston 21, and an end cap 23 fitted onto the massage head 22. The massage head assembly 20 is inserted into the housing 11 through an opening at the end of the housing 11 via the piston 21 and is connected to the first drive mechanism 30. The massage head 22 and its end cap 23 are exposed outside the opening. The outer diameter of the massage head 22 is larger than the opening diameter of the housing 11, restricting the massage head 22 from entering the housing 11.

[0046] When the massage head assembly 20 is driven to reciprocate axially in the handle 10 by the first drive mechanism 30, the first drive mechanism 30 mainly drives the piston 21 to move back and forth axially relative to the housing 11. To ensure the smooth reciprocating motion of the piston 21 and that it can move back and forth in a straight line, a piston sleeve 25 is provided between the piston 21 and the housing 11. The piston sleeve 25 is fitted around the outer periphery of the piston 21 and is fixedly engaged with the inner wall surface of the housing 11, allowing the piston 21 to move back and forth along the piston sleeve 25.

[0047] When the massage head assembly 20 performs impact massage, the massage head 22 and end cap 23 are the parts that come into contact with the user. To reduce the discomfort caused by the hard impact of the massage head 22 and end cap 23 on the user, the massage head assembly also includes a flexible cap 24 fitted onto the end cap 23. The flexible cap 24 can be a spherical structure or a conical structure. The flexible cap 24 can be made of flexible materials such as silicone, but is not limited to.

[0048] The massage head 22 and / or flexible cap 24 of the massage head assembly 20 may have the same or different shapes or settings; different settings provide different massage functions or experiences.

[0049] Depending on the functional requirements, the massage head assembly 20 may also have a heating function. For this purpose, heating elements can be provided on the end cap 23 and / or the massage head 22. These heating elements generate heat when powered on, thus providing the massage head assembly 20 with a heating function.

[0050] For the straight handle 10, two first drive mechanisms 30 can be symmetrically arranged at opposite ends of the housing 11 of the handle 10, and two sets of massage head assemblies 20 are also symmetrically fitted at the two ends of the housing 11.

[0051] like Figures 2-4As shown, the first drive mechanism 30 may further include a telescopic motor 31 and a first transmission assembly; the telescopic motor and the first transmission assembly are arranged axially within the handle 10, and the first transmission assembly is connected between the telescopic rod of the telescopic motor 31 and the massage head assembly 20. The telescopic motor 31 drives the massage head assembly 20 to reciprocate axially in the handle 10 via the first transmission assembly.

[0052] Specifically, the telescopic motor 31 is installed inside the housing 11 with an opening in the telescopic rod facing the housing 11. The first transmission assembly is connected between the telescopic rod and the piston 21 of the massage head assembly 20, and the three are relatively fixed. When the telescopic motor 21 is started, the telescopic rod performs a telescopic movement coaxial with the handle 10, which drives the piston 21 to reciprocate axially in the handle 10 through the first transmission assembly.

[0053] The first transmission assembly includes a transmission connector 32, which may have a first end 321 and a second end 322. The first end 321 of the transmission connector 32 is fixedly connected to the telescopic rod of the telescopic motor 31, and the second end 322 is fixedly connected to the piston 21 of the massage head assembly 20.

[0054] Alternatively, the second end 322 of the transmission connector 32 can be fixedly connected to the piston 21 using fasteners such as screws. Specifically, as shown in the figure... Figure 4 As shown, a connecting groove 211 can be provided on the end side of the piston 21 facing the transmission connector 32. The second end 322 of the transmission connector 32 fits into the connecting groove 211, keeping the transmission connector 32 and the piston 21 coaxial. Then, by inserting screws or other fasteners into the screw holes of the second end 322 of the transmission connector 32 and the connecting groove 211, the second end 322 of the transmission connector 32 is locked in the connecting groove 211. Alternatively, the second end 322 of the transmission connector 32 can be inserted into the end of the piston 21 facing the transmission connector 32, keeping the transmission connector 32 and the piston 21 coaxial. By inserting screws or other fasteners from the side of the piston 21 into the end of the piston 21 and the second end 322 of the transmission connector 32, it is locked between the end of the piston 21 and the second end 322 of the transmission connector 32.

[0055] Combination Figure 2 and Figure 5 The first end 321 of the transmission connector 32 is fixedly connected to the telescopic rod of the telescopic motor 31 and can move synchronously with the telescopic rod. To improve the movement stability of the transmission connector 32, and thus the movement stability of the massage head assembly 20, a guide frame 33 is provided on the telescopic motor 31, and the guide frame 33 is located on the periphery of the telescopic rod of the telescopic motor 31. The first end 321 of the transmission connector 32 is fitted onto the guide frame 33, and the transmission connector 32 moves back and forth along the guide frame 33 in the axial direction of the handle 10 under the extension and retraction of the telescopic rod.

[0056] Preferably, the first end 321 of the transmission connector 32 is a sleeve structure, which is movably sleeved on the outer periphery of the guide frame 33; the telescopic rod of the telescopic motor 31 passes through the middle of the guide frame 33 and connects to the first end 321 of the transmission connector 32. Under the extension and retraction of the telescopic rod, the transmission connector 32 moves back and forth axially along the outer periphery of the guide frame 33.

[0057] Furthermore, to control the travel of the transmission connector 32 and prevent it from moving too far axially and disengaging from the guide frame 33, a limiting member 34 is provided at the first end 321 of the transmission connector 32. The limiting member 34 is engaged inside the guide frame 33 and can move back and forth along the guide frame 33 with the transmission connector 32. When the limiting member 34 moves to the top of the guide frame 33 away from the telescopic motor 31, the limiting member 34 interferes with the top of the guide frame 33, restricting the transmission connector 32 from continuing to move and disengage from the guide frame 33.

[0058] exist Figure 5 and Figure 6 In the illustrated embodiment, the limiting member 34 is connected to the cylindrical wall of the first end 321 of the transmission connector 32, with one end protruding from the inner circumference of the first end 321. Corresponding to the connection of the limiting member 34, the cylindrical wall of the first end 321 may be provided with a notch 323 and a gasket 324 adapted to the notch 323. The limiting member 34 is clamped between the inner surfaces of the gasket 324 and the notch 323. The provision of the gasket 324 and the notch 323 ensures that the first end 321 of the transmission connector 32 is maintained while the limiting member 34 is installed.

[0059] The guide frame 33 is provided with a slot 331 extending along the height direction of the guide frame 33. The top of the slot 331 is located at the top of the guide frame 33 and a step 332 protrudes or covers the top of the slot 331. The end of the limiting member 34 protruding from the inner circumference of the first end 321 is engaged in the slot 331 and cannot be dislodged by itself. When the transmission connecting member 32 moves along the guide frame 33 towards its top, it drives the limiting member 34 to move along the slot 331 towards the top. When the limiting member 34 abuts against the step 332 at the top of the slot 331, the transmission connecting member 32 stops moving, thereby limiting the movement stroke of the transmission connecting member 32 on the guide frame 33.

[0060] Alternatively, the limiting member 34 can be a limiting post, and one end of it protruding into the first end 321 of the transmission connector 32 can be arc-shaped; the slot 331 of the guide frame 33 is correspondingly an arc-shaped slot.

[0061] Furthermore, in order to prevent the transmission connector 32 from moving circumferentially along the guide frame 33, a limiting structure is provided between the first end 321 of the transmission connector 32 and the guide frame 33, thereby restricting the circumferential movement of the transmission connector 32 relative to the guide frame 33.

[0062] refer to Figure 5 and Figure 6 In one embodiment, the limiting structure includes a protrusion 35 and a matching groove 36 that are adapted to each other. The protrusion 35 is disposed on the inner periphery of the first end 321 of the transmission connector 32, and the matching groove 36 is disposed on the outer periphery of the guide frame 33. The protrusion 35 can be embedded in the matching groove 36. The protrusion 35 alters the inner periphery shape of the first end 321 of the transmission connector 32; similarly, the matching groove 36 alters the outer periphery shape of the guide frame 33. When the first end 321 of the transmission connector 32 is fitted onto the outer periphery of the guide frame 33, the protrusion 35 is embedded in the matching groove 36 to achieve a concave-convex fit, preventing the first end 321 of the transmission connector 32 from rotating along the outer periphery of the guide frame 33.

[0063] Understandably, the positions of the protrusion 35 and the matching groove 36 can be interchanged. That is, the matching groove 36 is located on the inner periphery of the first end 321 of the transmission connector 32, and the protrusion 35 is located on the outer periphery of the guide frame 33. This can also restrict the circumferential movement of the transmission connector 32 relative to the guide frame 33.

[0064] In other embodiments, the inner circumference of the first end 321 of the transmission connector 32 is a non-circular structure, and the outer circumference of the guide frame 33 is a non-circular structure adapted to the inner circumference of the first end 321 of the transmission connector 32. After the transmission connector 32 is fitted onto the outer circumference of the guide frame 33, the transmission connector 32 can move back and forth along the height direction of the guide frame 33, but cannot move circumferentially relative to the guide frame 33. Therefore, the inner circumference of the non-circular structure and the outer circumference of the non-circular structure also form a limiting structure. The aforementioned non-circular structure can be a rectangle or other polygonal shape, an ellipse, or an irregular shape.

[0065] Furthermore, such as Figure 2 and Figure 3 As shown, the fascia gun also includes a power supply component 40 disposed in the handle 10; the power supply component 40 is electrically connected to the drive system, providing power to the drive system and controlling the start-up and shutdown and working mode of the drive system.

[0066] Specifically, the power supply assembly 40 is housed within the housing 11 of the handle 10. The power supply assembly 40 includes a battery 41 and a control board 42 electrically connected to the battery 41. The first drive mechanism 30 is electrically connected to the control board 42, and the control board 42 controls the battery 41 to supply power to the first drive mechanism 30.

[0067] Preferably, the battery 41 is coaxially arranged with the telescopic motor 31 of the first drive mechanism 30 and the massage head assembly 20, and the three are on the same straight line, which helps to smoothly set the handle 10 housing 11, avoids unnecessary extra volume, and ensures the integrity and aesthetics of the appearance.

[0068] The handle 10 is also equipped with an indicator light 13 and a switch 14 electrically connected to the power supply assembly 40. The indicator light 13 is specifically mounted on and electrically connected to the control board 42, and the housing 11 of the handle 10 has a lamp hole to expose the indicator light 13. The switch 14 is also mounted on and electrically connected to the control board 42, and the housing 11 of the handle 10 has a through hole to expose the switch 14. Corresponding to the two sets of first drive mechanisms 30, the handle 10 is equipped with at least two switches 14 to realize independent switching control of the two sets of first drive mechanisms 30.

[0069] The switch 14 can be a push-button switch, protruding from the through hole for easy pressing. Pressing the switch 14 turns the corresponding first drive mechanism 30 on or off, thereby turning the corresponding massage head assembly 20 on or off.

[0070] The fascia gun in the above embodiment is a double-headed fascia gun, and both sets of massage head assemblies 20 are located at the end of the handle 10, with their movement direction coaxial with the handle 10. In use, the user can activate either massage head assembly 20 according to their needs, hold the handle in any direction, and direct the massage head assembly towards the area requiring massage for impact-type massage. When both sets of massage head assemblies 20 are working, they can simultaneously massage the user's arms or legs, or even two people simultaneously, offering flexibility and enhancing the user experience.

[0071] like Figures 7-8 As shown, another embodiment of the fascia gun of this utility model includes a handle 10, two sets of massage head assemblies 20, and a drive system. Corresponding to the two sets of massage head assemblies 20, the drive system includes a first drive mechanism 30 and a second drive mechanism 50. The two first drive mechanisms 30 are arranged within the handle 10 corresponding to the two sets of massage head assemblies 20. The first drive mechanism 30 and the second drive mechanism 50 are connected to the corresponding massage head assemblies 20, driving the massage head assemblies 20 to reciprocate along the axial direction of the handle 10.

[0072] The arrangement of two sets of massage head assemblies 20 makes the fascia gun in this embodiment a double-headed fascia gun.

[0073] In this embodiment, the two sets of massage head assemblies 20 are divided into a first massage head assembly 201 and a second massage head assembly 202. The handle 10 includes a first end and a second end opposite to each other. The first massage head assembly 201 is movably fitted onto the end of the first end of the handle 10. A first drive mechanism 30 is disposed within the first end of the handle 10 and connected to the first massage head assembly 201, driving the first massage head assembly 201 to reciprocate in the axial direction of the handle 10. The second massage head assembly 202 is movably fitted onto the second end of the handle 10. A second drive mechanism 50 is connected to the second massage head assembly 202, driving the second massage head assembly 202 to reciprocate in a direction perpendicular to the axial direction of the handle 10.

[0074] The handle 10 includes a main housing 101 and a side housing 102. The main housing 101 has a first end and a second end, which respectively form the first end and the second end of the handle 10. The side housing 102 is perpendicular to the axial direction of the main housing 101 and is connected to the second end of the main housing 101, making the handle 10 generally L-shaped or 7-shaped. The inner cavity of the side housing 102 is connected to the inner cavity of the main housing 101.

[0075] The first massage head assembly 201 is movably fitted onto the end of the first end of the main housing 101, and the second massage head assembly 202 is movably fitted onto the end of the side housing 102 away from the main housing 101.

[0076] For ease of grip, the main housing 101 of the handle 10 has a cylindrical structure. The first end of the main housing 101 is open, forming an opening through which the first massage head assembly 201 fits and extends into the main housing 101 to connect with the first drive mechanism 30; the second end of the main housing 101 is closed. The end of the side housing 102 away from the main housing 101 is open, forming an opening through which the second massage head assembly 202 fits and extends into the side housing 102 to connect with the second drive mechanism 50.

[0077] The outer shell, consisting of the main housing 101 and the side housing 102, can preferably be configured as separate parts, such as by joining two L-shaped or 7-shaped half-shells together. The separate outer shell facilitates the installation of the first drive mechanism 30, the second drive mechanism 50, and the massage head assembly 20, etc.

[0078] The outer surface of the main housing 101 can be padded to improve the feel, increase grip comfort, and also provide anti-slip properties. For details on the padded layer, please refer to [reference needed]. Figure 1 The cushion layer of the embodiment shown.

[0079] The first massage head assembly 201 and the second massage head assembly 202 have the same structure; please refer to [reference needed]. Figures 1-6 The massage head assembly 20 in the illustrated embodiment also includes a piston 21, a massage head 22, an end cap 23, and a flexible cap 24, etc. The detailed structure will not be described here.

[0080] The first drive mechanism 30 is housed within the first end of the main housing 101, corresponding to the first massage head assembly 201, and is connected to the first massage head assembly 201 via an end opening at the first end. The structural composition of the first drive mechanism 30 and its connection method with the first massage head assembly 201 can be found in [reference needed]. Figures 1-6 The first drive mechanism 30 and the massage head assembly 20 in the illustrated embodiment will not be described in detail here.

[0081] Unlike Figures 1-6In the illustrated embodiment, the second massage head assembly 202 is fitted to the end of the side housing 102 and reciprocates in the direction perpendicular to the axial direction of the handle 10 under the drive of the second drive mechanism 50. Compared to Figures 1-6 The fascia gun of the embodiment shown has two massage head assemblies 20 with different movement directions, which can simultaneously perform impact massage on the user's parts in different directions to meet the user's different usage needs.

[0082] like Figure 2 As shown, the second drive mechanism 50 may include a drive motor 51 and a second transmission assembly. The drive motor 51 is mainly a rotary motor. The second transmission assembly is connected between the output shaft of the drive motor 51 and the second massage head assembly 202, converting the rotation of the output shaft of the drive motor 51 into the linear reciprocating motion of the second massage head assembly 202.

[0083] The second transmission assembly may specifically include an eccentric wheel 52 and a rocker arm 54. The eccentric wheel 52 is connected to the output shaft of the drive motor 51, and the eccentric wheel 52 is provided with an eccentric shaft 53 offset from the output shaft; one end of the rocker arm 54 is rotatably sleeved on the eccentric shaft 53, and the other end of the rocker arm 54 is connected to the second massage head assembly 202, specifically to the piston 21 of the second massage head assembly 202.

[0084] Specifically, since the drive motor 51 is located inside the main housing 101 and the second massage head assembly 202 is located inside the side housing 102, the drive motor 51 and the second massage head assembly 202 are arranged at a 90° angle, i.e., perpendicular to each other. In the second transmission assembly, the eccentric wheel 52 is connected to the output shaft of the drive motor 51, and the axial direction of the eccentric shaft 53 on the eccentric wheel 52 is parallel to the axial direction of the output shaft of the drive motor 51. The rocker arm 54 is arranged with its length direction perpendicular to the axial direction of the eccentric shaft 53, one end is connected to the eccentric shaft 53, and the other end passes into the end of the piston 21 and is fixedly connected to the piston 21.

[0085] After the drive motor 51 starts, it outputs rotational motion through the output shaft. The output shaft drives the eccentric wheel 52 to rotate around the output shaft. The eccentric shaft 53 deviates from the output shaft, thus, driven by the eccentric wheel 52, the eccentric shaft 53 forms a circular motion around the output shaft. The rocker arm 54 is driven by the eccentric shaft 53 to rotate, so that the rocker arm 54 can perform another circular motion around the circle deviating from the output shaft, and at the same time, it forms a back-and-forth motion of a certain distance in the horizontal direction perpendicular to the axis of the eccentric shaft 53. The direction of motion is as follows: Figure 2 As shown by the dashed arrow, the piston 21 is parallel to the rocker arm 54, and therefore, driven by the back-and-forth movement of the rocker arm 54, it also performs a reciprocating motion in the same straight line, driving the second massage head assembly 202 to form an impact-type massage action.

[0086] The fascia gun in this embodiment also includes a power supply component 40 disposed in the handle 10; the power supply component 40 is electrically connected to the first drive mechanism 30 and the second drive mechanism 50 respectively, and can independently control the start / stop, working mode, etc. of the first drive mechanism 30 and the second drive mechanism 50.

[0087] For details on the power supply component 50, the indicator lights and switches on the handle 10, please refer to [the relevant documentation / reference]. Figures 1-6 The embodiments shown are not described in detail here.

[0088] When using the fascia gun in this embodiment, the user can activate either massage head assembly 20 (first massage head assembly 201 or second massage head assembly 202) according to their needs; the user can hold the handle in any direction and point the first massage head assembly 201 toward the area to be massaged for impact massage. When both sets of massage head assemblies 20 are working, they can simultaneously perform impact massage on different body parts, making it flexible to use and improving the user experience.
