[0039] Example 1

[0040] like Figures 1 to 9 As shown, the embodiment of the present invention provides a fascia gun, including a shell 10, a bracket 20, a motor 30, a telescopic member 40, a transmission assembly 50 and a massage head 60, wherein the bracket 20 includes a first frame 21 and a second frame 22, the first frame 21 is used to support the shell 10, and the second frame 22 is located outside the shell 10. The axis of the first frame 21 and the axis of the second frame 22 are distributed at an angle, and the first frame 21 is provided with a first through hole 211 that passes through along its own axis, and the second frame 22 is provided with a second through hole 221 that passes through along its own axis, and the first through hole 211 and the second through hole 221; the motor 30 is disposed in the housing 10 and fixed to the first frame 21. The motor shaft 31 of the motor 30 is located in the first through hole 211, and the axis of the motor shaft 31 is parallel to the axis of the first through hole 211. A portion of the telescopic member 40 is located in the second through hole 221, and the other portion is exposed outside the second frame 22. The transmission assembly 50 is used to connect the motor shaft 31 and the telescopic member 40, and is used to convert the rotation of the motor shaft 31 into reciprocating movement of the telescopic member 40 along the axis of the second through hole 221. The massage head 60 is connected to the portion of the telescopic member 40 located outside the second frame 22. The motor 30 drives the telescopic member 40 to reciprocate through the transmission assembly 50, and the telescopic member 40 then drives the massage head 60 to reciprocate to achieve a massage operation.

[0041] By setting up the bracket 20, the shell 10 can be fixed on the bracket 20, the motor 30 set in the shell 10 can also be fixed on the bracket 20, and the connecting rod 52 and the telescopic member 40 can also be installed in the bracket 20, that is, the bracket 20 can serve as the installation basis for other structures. On the one hand, the size of the shell 10 is reduced to meet the portability requirements, and on the other hand, the rigidity of the overall structure is improved.

[0042] Reference Figure 1 and Figure 2 In this embodiment, the angle between the first frame 21 and the second frame 22 is a right angle. This makes it easier for the transmission assembly 50 to connect the motor shaft 31 and the telescopic member 40. Alternatively, in other embodiments, the angle between the first frame 21 and the second frame 22 can be an acute angle or an obtuse angle, and is not limited to this embodiment.

[0043] In this embodiment, the transmission assembly 50 includes a crank pulley 51 and a connecting rod 52. The crank pulley 51 is connected to the motor shaft 31. One end of the connecting rod 52 is connected to the crank pulley 51 via a first rotating shaft 53, and the other end is connected to the telescopic member 40 via a second rotating shaft 54. The axis of the motor shaft 31 is parallel to the axis of the first rotating shaft 53 and is spaced apart, i.e., the crank pulley 51 has an eccentric structure. The motor 30 can drive the crank pulley 51 to rotate. When the crank pulley 51 rotates, it can pull the connecting rod 52 to move, and then pull the telescopic member 40 to move through the connecting rod 52. Because the motion trajectory of the telescopic member 40 is limited by the second through hole 221, the telescopic member 40 can only be driven to reciprocate along the axis of the second through hole 221.

[0044] Furthermore, the first frame 21 and the second frame 22 are connected in a T-shape. With this arrangement, the structure of the housing 10 can be simplified and the size of the housing 10 can be reduced.

[0045] In this embodiment, the housing 10 includes a first housing 11 and a second housing 12, and the first housing 11 and the second housing 12 are distributed along the axis of the first frame 21. In some embodiments, as Figures 1 to 6 As shown, the first frame 21 is located inside the shell 10, and the first shell 11 and / or the second shell 12 are provided with avoidance holes, and the second frame 22 is exposed to the shell 10 through the avoidance holes. Optionally, both the first shell 11 and the second shell 12 may be provided with half avoidance holes 13, and the two half avoidance holes 13 are enclosed to form an avoidance hole. Alternatively, one of the first shell 11 and the second shell 12 may be provided with a complete avoidance hole. The first shell 11 and the second shell 12 together constitute a cylindrical shell 10 structure, which can improve the comfort of holding, thereby improving the user experience. In some embodiments, such as Figures 7 to 9 As shown, the first frame 21 and the second frame 22 are both located outside the housing 10. Specifically, the first housing 11 is connected to one end of the first frame 21 along the axis, and the second housing 12 is connected to the other end of the first frame 21 along the axis. Optionally, the first and second housings 11, 12, and the first frame 21 can be connected by screwing, snapping, bonding, or welding. The first housing 11, second housing 12, and first frame 21 together form a cylindrical housing 10 structure, which improves grip comfort and thus enhances the user experience.

[0046] In this embodiment, the fascia gun is T-shaped as a whole, with a compact appearance and is easy to carry.

[0047] In this embodiment, a sliding sleeve 70 is disposed within the second through hole 221 and slides with the telescopic member 40. The provision of the sliding sleeve 70 prevents sliding wear between the telescopic member 40 and the bracket 20. Furthermore, a limiting groove is provided in the wall of the second through hole 221, with the sliding sleeve 70 partially positioned within the limiting groove. One end of the sliding sleeve 70 abuts against the groove wall of the limiting groove, while the other end of the sliding sleeve 70 is limited by a limiting housing 80. The limiting housing 80 is sleeved around the outer periphery of the telescopic member 40 and connected to the second frame 22. Optionally, the connection between the limiting housing 80 and the second frame 22 can be threaded, clipped, bonded, or welded.

[0048] Furthermore, the first frame 21 includes a main frame 21 a and a detachable frame 21 b , and the main frame 21 a and the detachable frame 21 b are detachably connected to each other, thereby facilitating the assembly and disassembly of the motor 30 and the first frame 21 .

[0049] Reference Figures 3 to 6 Specifically, the inner walls of the main frame 21a and / or the detachable frame 21b are provided with fixing grooves 212. A stator bracket 32 ​​is connected to the stator of the motor 30, and the stator bracket 32 ​​engages with the fixing grooves 212. When assembling the motor 30 with the first frame 21, the stator bracket 32 ​​is first inserted into the fixing grooves 212, and then the detachable frame 21b is connected to the main frame 21a.

[0050] In this embodiment, there are two fixing slots 212, one of which is provided on the main frame 21a, and the other is provided on the removable frame 21b. The two ends of the stator bracket 32 ​​are inserted into the two fixing slots 212 in a one-to-one correspondence. When assembling the motor 30 with the first frame 21, one end of the stator bracket 32 ​​is first inserted into the fixing slot 212 of the main frame 21a, and then the fixing slot 212 of the removable frame 21b is aligned with the other end of the stator bracket 32 ​​and inserted. After that, the removable frame 21b is connected to the main frame 21a, thereby securing the stator bracket 32. In other embodiments, the fixing slot 212 may be provided only on the main frame 21a, or only on the removable frame 21b. In other embodiments, the number of fixing slots 212 may be one or more than two. The number of the fixing slots 212 and their distribution on the main frame 21 a and the detachable frame 21 b are not limited to this embodiment, as long as the stator bracket 32 ​​can be fixed.

[0051] Optionally, the main frame 21a and the detachable frame 21b are connected by a first fastener 21c, the axis of the first fastener 21c being perpendicular to the axis of the first frame 21. The detachable frame 21b is provided with a first connection hole 213, and the main frame 21a is provided with a second connection hole 214. The first fastener 21c connects the detachable frame 21b to the main frame 21a through the first connection hole 213 and the second connection hole 214, resulting in a simple, reliable connection and easy assembly and disassembly. Alternatively, the main frame 21a and the detachable frame 21b can also be connected by a snap-fit ​​connection, which is not limited to this embodiment.

[0052] In this embodiment, the outer wall of the detachable frame 21b is provided with a groove, and the first connection hole 231 is provided at the bottom of the groove. This allows the first fastener 21c to be hidden within the groove, thereby preventing the first fastener 21c from occupying space. The inner wall of the main frame 21a is provided with an ear seat, and the second connection hole 214 is provided in the ear seat, thereby facilitating the opening of the second connection hole 214.

[0053] Optionally, the fixing groove 212 is composed of two limiting ribs 2121 and two limiting holes 2122. The two limiting ribs 2121 are spaced apart along the axial direction of the first through hole 211. The two limiting holes 2122 are both arranged between the two limiting ribs 2121 and spaced apart along the circumference of the first through hole 211. Two limiting protrusions 321 are provided at the end of the stator bracket 32. The end of the positioning bracket 20 can be inserted between the two limiting ribs 2121. At the same time, the two limiting protrusions 321 on the stator bracket 32 ​​can be inserted into the two limiting holes 2122 one by one, so that the movement of the positioning bracket 20 along the axial direction of the first through hole 211 and the rotation around the axial direction of the first through hole 211 are both restricted. Alternatively, the fixing groove 212 may be composed of four limiting ribs 2121, wherein two limiting ribs 2121 are spaced apart along the axis of the first through hole 211, and the other two limiting ribs 2121 are spaced apart along the circumference of the first through hole 211, with the four limiting ribs 2121 collectively enclosing the fixing groove 212. Alternatively, the fixing groove 212 may be formed by directly forming a depression in the wall of the first through hole 211, and the present embodiment is not limited thereto.

[0054] The motor 30 is housed within the first housing 11. The housing 10 conceals the first frame 21 and the motor 30, resulting in a simple and aesthetically pleasing overall appearance. The fascia massage gun provided in this embodiment of the utility model also includes a battery pack 90, which is housed within the second housing 12 and electrically connected to the motor 30 to provide power to the motor 30. Alternatively, the fascia massage gun can also be powered directly from an electrical outlet, and this is not limited to this embodiment.

[0055] Example 2

[0056] like Figures 10 to 12As shown, this embodiment provides a fascia gun, which is basically the same as the fascia gun of the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described in this embodiment. Specifically, the difference between this embodiment and the first embodiment lies in the fixing method of the stator bracket 32 ​​and the first frame 21.

[0057] In this embodiment, the stator bracket 32 ​​is connected to the first frame 21 via a second fastener 23 .

[0058] Optionally, the end of the first frame 21 is provided with an inwardly folded flange 215, and the stator bracket 32 ​​is connected to the flange 215 via a second fastener 23. The flange 215 is provided with a third connection hole 2151, and the stator bracket 32 ​​is provided with a fourth connection hole 322. The second fastener 23 connects the flange 215 to the stator bracket 32 ​​via the third connection hole 2151 and the fourth connection hole 322. The axis of the second fastener 23 is parallel to the axis of the first frame 21, making the connection simple, reliable, and easy to assemble and disassemble. Alternatively, the flange 215 can be omitted and the third connection hole 2151 can be provided directly at the end of the first frame 21, which is not limited to this embodiment. In this embodiment, the stator bracket 32 ​​is cross-shaped, and all four ends of the stator bracket 32 ​​are connected to the flange 215 via the second fastener 23, which ensures a secure connection while saving material. Of course, the stator bracket 32 ​​can also be circular, rectangular, or other shapes, and is not limited to this embodiment.

[0059] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
