[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0031] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0032] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of such features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] At present, the massage head of the fascia gun is generally plugged in and out by silicone extrusion and / or single-head threading. After a period of use, the silicone extrusion loses its elasticity due to fatigue, which in turn affects the plugging and unplugging of the massage head and causes it to loosen. Although the single-head threading method can solve the problem of silicone fatigue, it also has disadvantages, namely, the extension direction of the massage head cannot be positioned. When using a massage head with directional requirements such as a U-shaped head, due to processing limitations, the U-shaped head will form an angle with the piston of the fascia gun after installation, and cannot be horizontal or vertical, affecting the user experience.

[0034] The utility model provides a fascia gun.

[0035] See also Figures 1 to 3In one embodiment of the present invention, the fascia gun 100 includes a housing 110, a driving mechanism, and a massage head 140. The housing 110 is provided with a receiving chamber and an opening 110a communicating with the receiving chamber is provided on the surface of the housing 110. The driving mechanism includes a driving assembly 120 and a piston 130. The driving assembly 120 is provided in the receiving chamber. The piston 130 is movably provided at the opening 110a and is transmission-connected to the driving assembly 120. The driving assembly 120 is used to drive the piston 130 to perform high-frequency reciprocating motion along a first direction at the opening 110a. A positioning portion 141 is provided on one end of the massage head 140 for connecting with the piston 130. The piston 130 is provided with a positioning portion 141. A positioning fitting portion 131 is provided on the top, and the positioning portion 141 and the positioning fitting portion 131 are limitedly connected so that the length direction of the massage head 140 is set along the first direction, that is, the length direction of the massage head 140 is consistent with the movement direction of the piston 130, to ensure that the massage head 140 of the fascia gun 100 remains horizontal and vertical during use, so as to ensure the maximization of the massage effect. Specifically, the second direction is the length direction of the fascia gun 100, and the first direction and the second direction are perpendicular. When the user keeps the massage head 140 horizontal and vertical during use, the pressure applied by the user is evenly distributed, and the correct angle can effectively massage deep tissue, improve the massage effect and enhance the user experience.

[0036] In one embodiment, one of the positioning portion 141 and the positioning matching portion 131 is a multi-threaded external thread, and the other is a multi-threaded internal thread. The multi-threaded external thread and the multi-threaded internal thread are limit-connected so that the length direction of the massage head 140 is set along the first direction.

[0037] like Figures 3 to 6 As shown, in one embodiment of the present invention, the massage head 140 and the piston 130 are connected using a threaded structure. To ensure that the length of the massage head 140 is aligned with the direction of movement of the piston 130, a multi-start external thread or a multi-start internal thread can be used for the connection. Specifically, the positioning portion 141 can be a multi-start external thread provided on the massage head 140, and the positioning mating portion 131 can be a multi-start internal thread provided on the piston 130. Vice versa, the multi-start external thread and the multi-start internal thread can be three-start threads or four-start threads. Both structures provide positioning functions and have good stability. For example, when the three-start external thread is connected to the internal thread, the extension direction of the massage head 140 is aligned with the first direction of movement of the piston 130, thereby maintaining the massage head 140 horizontal and vertical to prevent deviation. Compared to the three-start thread, the four-start thread has higher load bearing capacity and positioning accuracy, and correspondingly greater processing precision. Therefore, the choice of the multi-start thread in the specific embodiment can be considered based on factors such as cost and structure. In addition to the three-start and four-start threads mentioned above, other multi-start thread structures that can also achieve positioning are also available, and are not specifically limited here.

[0038] In one embodiment, one of the positioning portion 141 and the positioning mating portion 131 is a three-start external thread, and the other is a three-start internal thread, and the angle between the projections of each thread of the three-start external thread or the three-start internal thread on a plane perpendicular to the first direction is greater than or equal to 119.5° and less than or equal to 120.5°.

[0039] like Figure 5 and Figure 6 As shown, in one embodiment of the present invention, one of the positioning portion 141 and the positioning matching portion 131 is set as a three-start external thread, and the other is set as a three-start internal thread. Specifically, the axial direction of the piston 130 is the first direction, and the threads of the three-start external thread or the three-start internal thread form a projection on a plane perpendicular to the axial direction of the piston 130. Please refer to Figure 5 , three dotted lines extend from the central axis toward the starting positions of the three screw teeth respectively. The angle between the three screw teeth is α. Due to errors in the processing process, the range of the angle is: 119.5°≤α≤120.5°, that is, the angle of α can be 119.5°, 120°, 120.5°, or any value in the aforementioned range. The angle between the tooth tops of the three screw teeth is also α. For further reference Figure 6 The angle between the three threads of the three-start internal thread is β, and the range of the angle is: 119.5°≤β≤120.5°, that is, the angle of β can be 119.5°, 120°, 120.5°, or any value in the aforementioned range, so that β corresponds to α, and the three-start external thread is screwed into the three-start internal thread, and the top and bottom of the threads of the two are abutted, so that the length direction of the massage head 140 coincides or nearly coincides with the axial direction of the piston 130, and the extension direction of the massage head 140 is consistent with the first direction, which can enhance the user's massage experience.

[0040] In one embodiment, the pitches of the threads of the three-start external thread and the three-start internal thread are equal and the number of thread starts is a multiple of 3.

[0041] In one embodiment of the present invention, the pitch of the threads of the three-start external thread and the three-start internal thread is equal, and the number of thread starts is a multiple of 3. Specifically, the equal pitch of the three-start external thread and the three-start internal thread ensures consistent thread fit, allowing for precise docking of the internal and external threads. The equal pitch evenly distributes the contact area, helping to disperse the load and improve the strength and stability of the connection. The standardized design simplifies production and reduces costs. The number of thread starts (threads) is set to a multiple of 3, and the multiple threads are projected onto a plane perpendicular to the first direction and are evenly spaced around the first direction. The crest of each thread of the external thread abuts the root of the internal thread, forming multiple annular support points, so that the length direction of the massage head is consistent with the axis direction of the piston.

[0042] In one embodiment, the massage head 140 includes a massage portion 142 and a connecting portion 143 ; the connecting portion 143 is rod-shaped and the positioning portion 141 is disposed on the outer surface of the connecting portion 143 ; the piston 130 is provided with a slot 130 a , and the positioning portion 131 is disposed within the slot 130 a ;

[0043] Alternatively, the end of the piston 130 away from the driving assembly 120 is rod-shaped and the positioning matching portion 131 is provided at the end of the piston 130 away from the driving assembly 120, and a slot 130a is provided on the connecting portion 143 of the massage head 140, and the positioning portion 141 is provided in the slot 130a.

[0044] like Figure 3 As shown, in one embodiment of the present invention, the massage head 140 includes a massage portion 142 and a connecting portion 143. The connecting portion 143 is a rod-shaped structure with three external threads on its outer surface. The end of the piston 130 away from the drive assembly 120 is provided with a slot 130a, and the inner wall of the slot 130a is provided with three internal threads. The connecting portion 143 is screwed into the slot 130a of the piston 130, and the three internal threads and the three external threads are used to limit the position, so that the entire length of the massage head 140 is arranged along the first direction. Alternatively, the connecting portion 143 of the massage head 140 has a slot 130a on one end facing the piston 130, and the slot 130a is provided with three internal threads. The end of the piston 130 away from the drive assembly 120 is rod-shaped and has three external threads on its outer surface, so as to connect with the three internal threads of the massage head 140. As can be seen from the above, the connection structure between the connection portion 143 of the massage head 140 and the piston 130 is not specifically limited, and the length direction of the massage head 140 is set along the first direction.

[0045] In one embodiment, the fascia gun 100 further includes a silicone ring 150 , which is sleeved on the massage head 140 or the piston 130 , and the massage head 140 and the piston 130 clamp the silicone ring 150 .

[0046] like Figure 3 and Figure 6As shown, in one embodiment of the present invention, the fascia gun 100 also includes a silicone ring 150. Specifically, the silicone ring 150 is used to be sleeved on the connecting portion 143 of the massage head 140 or the piston 130. When the massage head 140 and the piston 130 are connected, the two clamp the silicone ring 150 to deform it. The elastic force generated by the silicone ring 150 locks the three-head internal thread and the three-head external thread to prevent the massage head 140 from loosening during use. Some conventional massage heads 140 use a silicone sleeve structure to have an interference fit with the slot 130a of the piston 130. The silicone sleeve is prone to fatigue, causing the massage head 140 to loosen. The massage head 140 with a single-head thread connection is better tightened with the silicone ring 150, but the direction is difficult to control. In this application, the three-head external thread and the three-head internal thread are used to solve the problem of positioning the massage head 140.

[0047] In one embodiment, the connecting portion 143 is rod-shaped and has a mounting groove 140a on its outer surface. The mounting groove 140a is spaced apart from the positioning portion 141 and is located on the side of the positioning portion 141 close to the massage portion 142. The silicone ring 150 is embedded in the mounting groove 140a and its two ends are respectively in contact with the massage head 140 and the piston 130.

[0048] like Figure 3 、 Figure 4 and Figure 6 As shown, in one embodiment of the present invention, the connecting portion 143 is rod-shaped and has a three-head external thread on its outer surface. The piston 130 is provided with a slot 130a and the inner wall of the slot 130a is provided with a three-head internal thread. The connecting portion 143 is also provided with an annular positioning groove, which is located on the side of the three-head external thread close to the massage portion 142, and the side wall of the positioning groove away from the three-head external thread forms a step and matches the end face of the piston 130 facing the massage head 140. Please refer to Figure 6 The silicone ring 150 is embedded in the positioning groove. As the three-head external thread is screwed into the three-head internal thread, the piston 130 moves away from the annular end surface of the driving assembly 120 toward the massage part 142 and abuts against the silicone ring 150. The side wall of the positioning groove and the piston 130 clamp and squeeze the silicone ring 150 to cause it to produce elastic deformation, thereby providing pre-tightening force to the three-head external thread and the three-head internal thread to prevent the massage head 140 from loosening.

[0049] In one embodiment, the massage part 142 includes a first massage arm 1421 and a second massage arm 1422 . One end of the first massage arm 1421 and the second massage arm 1422 are connected to the connection part 143 , and the other ends of the first massage arm 1421 and the second massage arm 1422 are spaced apart along the first direction.

[0050] like Figure 1 、 Figure 2 and Figure 3As shown, in one embodiment of the present invention, the massage part 142 includes a first massage arm 1421 and a second massage arm 1422. Specifically, one end of the first massage arm 1421 and the second massage arm 1422 is connected to the end of the connecting part 143 away from the piston 130, and the first massage arm 1421 and the second massage arm 1422 are forked at one end away from the connecting part 143 and extend respectively in a first direction to form a U-shaped structure. The massage head 140 is a conventional U-shaped massage head 140. If the U-shaped massage head 140 forms an angle with the piston 130, it may cause uneven pressure during use and thus cause damage to muscles or tissues. Therefore, when using a threaded connection U-shaped massage head 140, it is necessary to consider whether the extension direction of the first massage arm 1421 and the second massage arm 1422 is consistent with the movement direction of the piston 130. The present application achieves positioning through three external threads and three internal threads, which effectively avoids the deviation of the extension direction of the first massage arm 1421 and the second massage arm 1422.

[0051] In one embodiment, the drive assembly 120 further includes a bearing 121 and a connecting rod 122. Bearings 121 are provided at both ends of the connecting rod 122. The end of the piston 130 away from the massage head 140 is rotatably connected to one end of the connecting rod 122 through the bearing 121, and the other end of the connecting rod 122 is connected to the eccentric wheel through another bearing 121.

[0052] like Figure 3 and Figure 7 As shown, in one embodiment of the present invention, the driving assembly 120 includes a bearing 121, a connecting rod 122, an eccentric wheel (not shown) and a motor (not shown). Specifically, the motor is installed in the housing 110 through a motor bracket, the eccentric wheel is provided on the output shaft of the motor, and a bearing 121 is embedded at each end of the connecting rod 122. The end of the piston 130 away from the massage head 140 is rotatably connected to the connecting rod 122 through one of the bearings 121, and the eccentric wheel is rotatably connected to another transmission shaft on the connecting rod 122. The motor drives the eccentric wheel to rotate, and the connecting rod 122 drives the piston 130 to perform high-frequency reciprocating motion at the opening 110a of the housing 110.

[0053] In one embodiment, one end of the piston 130 away from the driving assembly 120 at least partially extends out of the housing 110 from the opening 110 a .

[0054] like Figure 1As shown, in one embodiment of the present invention, the piston 130 is cylindrical and one end away from the connecting rod 122 extends out of the shell 110, so that different types of massage heads 140 can be easily replaced to meet different massage needs (such as for different muscle groups or pain points). The piston 130 is constrained by the front shell of the shell 110 and the bushing inside the front shell to limit the movement of the piston 130 along its own axial direction. The front end of the piston 130 extends and abuts against the shell 110 during use to avoid deviation, thereby improving the overall structural strength of the fascia gun 100. The piston 130 extending out of the shell 110 helps to more accurately control the position and direction of the massage head 140, thereby improving the accuracy and effect of the operation.

[0055] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
