Description

Technical Field

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

[0002] With the popularization of healthy living concepts and the continuous expansion of the sports population, fascia guns, as a highly efficient muscle relaxation tool, have gained widespread popularity. Fascia guns transmit mechanical force to deep muscle tissue through high-frequency vibration, effectively relieving muscle soreness and stiffness after exercise; their efficacy has been recognized in the field of sports medicine. Traditional fascia guns use high-power motors and are equipped with various replaceable massage heads, providing a powerful deep massage effect. However, their large size and weight limit their portability, making them difficult to meet the needs of sports enthusiasts who want to carry them with them.

[0003] To adapt to market demands, fascia gun products are gradually developing towards lightweight and miniaturization. Portable fascia guns, while maintaining basic massage functions, have significantly reduced their overall size and weight, making them easy for users to carry in gym bags or even pockets. However, this miniaturization design brings challenges to the internal structural layout: the compact body space needs to accommodate core components such as the motor, control circuitry, and battery, requiring higher precision in the installation and fit between these components. As the core component of the drive system, the motor's vibration characteristics directly affect the massage effect, but the motor's own vibration during operation also poses structural stability issues. Existing technology typically uses a bracket mounting method parallel to the motor's axis. While this design provides stable support, it requires a large axial installation space, limiting further reduction in product size and impacting improvements in portability.

[0004] Therefore, there is an urgent need to provide a portable fascia gun to solve the above problems to some extent. Utility Model Content

The screwing part is embedded in the bearing section, and the locking part passes through the connecting section and connects to the first positioning hole or the second positioning hole.

[0009] The housing has a first positioning groove corresponding to the position of the first mating groove and a second positioning groove corresponding to the position of the second mating groove. The accommodating space shape of the first positioning groove and the second positioning groove is adapted to the outer contour shape of the first mating groove and the second mating groove.

[0011] The portable fascia gun provided by this utility model also includes a motor. The positioning frame has a through hole and a limiting protrusion at the position corresponding to the output shaft of the motor. The output shaft of the motor passes through the limiting protrusion and the through hole. The limiting protrusion is located between the positioning frame and the housing of the motor, and the end of the limiting protrusion away from the positioning frame abuts against the housing of the motor.

[0012] Specifically, the portable fascia gun provided by this utility model also includes an eccentric wheel, a connecting rod, a piston, and a massage head; the eccentric wheel is connected to the output shaft, one end of the connecting rod is rotatably connected to the eccentric wheel, and the other end is rotatably connected to one end of the piston, and one end of the massage head is connected to the other end of the piston.

[0013] Furthermore, one end of the piston forms a connecting platform and a connecting post, and the other end forms a threaded hole. One end of the massage head forms a screw, and the massage head is threadedly connected to the threaded hole. The connecting post is formed on the connecting platform and extends vertically. The end of the connecting rod away from the eccentric wheel is rotatably connected to the connecting post.

[0017] Analysis shows that by forming a first positioning post and a second positioning post inside the housing, and a first mating groove formed by the positioning frame corresponding to the first positioning post and a second mating groove formed by the positioning frame corresponding to the second positioning post, positioning between the positioning frame and the housing can be achieved by inserting the first positioning post into the first mating groove and the second positioning post into the second mating groove.

[0018] Since the first and second positioning posts in this application can extend along the thickness direction of the shell, the axes of the first and second mating grooves also extend along the thickness direction of the shell. This allows the positioning frame provided in this application to be installed in the thickness direction of the shell, i.e., the horizontal direction, during installation. This can save the product's height dimension to a certain extent, ensuring the miniaturization of the fascia gun and making it convenient for users to carry. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0025] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0027] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0028] The following describes in detail the overall structure, working principle, and technical effects of the portable fascia gun provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0029] like Figures 1-4 As shown, the portable fascia gun provided in this application includes a housing 1 and a positioning frame 2. A first positioning post 103 and a second positioning post 104 are formed inside the housing 1 along the thickness direction of the housing 1. The positioning frame 2 has a first mating groove 201 and a second mating groove 202 corresponding to the positions of the first positioning post 103 and the second positioning post 104. The first positioning post 103 is inserted into the first mating groove 201 and the second positioning post 104 is inserted into the second mating groove 202, so that the positioning frame 2 is connected to the housing 1.

[0030] Compared with existing technologies, the portable fascia gun provided in this application has the following advantages: The portable fascia gun provided in this application has a first positioning post 103 and a second positioning post 104 formed inside the housing 1, and a first mating groove 201 formed by the positioning frame 2 corresponding to the first positioning post 103 and a second mating groove 202 formed by the second positioning post 104. Thus, the positioning frame 2 and the housing 1 can be positioned by inserting the first positioning post 103 into the first mating groove 201 and the second positioning post 104 into the second mating groove 202.

[0031] Since the first positioning post 103 and the second positioning post 104 in this application can extend along the thickness direction of the housing 1, the axes of the first mating groove 201 and the second mating groove 202 also extend along the thickness direction of the housing 1. This allows the positioning frame 2 provided in this application to be installed in the thickness direction of the housing 1, i.e., the horizontal direction, during the installation process. This can save the product's height dimension to a certain extent, ensuring the miniaturization of the fascia gun and making it convenient for users to carry.

[0032] It is understandable that, such as Figure 4 As shown, in this application, the output shaft of the motor 8 extends in the vertical direction. When the traditional positioning frame 2 positions the motor 8, the fixing direction is parallel to the output shaft of the motor 8. However, in this application, the motor 8 is installed in a direction perpendicular to the output shaft of the motor, which can save the product's height dimension to a certain extent. This allows the portable fascia gun provided by this application to have a smaller and more flexible size and structural layout.

[0033] It should be noted here that the thickness and height directions mentioned above in this application are both based on... Figure 4 The angle shown in the figure is used as a reference. After the positioning frame 2 is connected to the housing 1, the two can be fixedly connected by adhesive or hot melting, so as to ensure the connection stability and avoid the problem of the motor 8 shaking due to the loosening of the positioning frame 2.

[0034] Optionally, such as Figures 1-4 As shown, the portable fascia gun of this application also includes a first locking member and a second locking member; the first positioning post 103 forms a first locking hole, the second positioning post 104 forms a second locking hole, the positioning frame 2 forms a first positioning hole 205 communicating with the first mating groove 201 and a second positioning hole 206 communicating with the second mating groove 202; the first locking member passes through the first positioning hole 205 and connects to the first locking hole, and the second locking member passes through the second positioning hole 206 and connects to the second locking hole.

[0035] Preferably, both the first locking member and the second locking member in this application can be bolts or screws. Correspondingly, the first locking hole, the second locking hole, the first positioning hole 205 and the second positioning hole 206 are all screw holes. Therefore, the first locking member and the second locking member in this application have an installation direction along the thickness direction of the housing 1. Thus, without increasing the thickness direction, the vertical dimension can be reduced to a certain extent.

[0036] More preferably, the first positioning hole 205 and the second positioning hole 206 in this application are both stepped holes, and include a bearing section 207 and a connecting section 208. The first locking member and the second locking member both include a screwing part and a locking part. The diameter of the screwing part is larger than the diameter of the locking part. The screwing part is embedded in the bearing section 207, and the locking part passes through the connecting section 208 and connects to the first positioning hole 205 or the second positioning hole 206.

[0037] It is understood that since the first and second locking members in this application adopt a bolt or screw structure, they have a large-diameter screwing part and a locking part for connection, i.e., a rod body. By making the first positioning hole 205 and the second positioning hole 206 into stepped holes, including a bearing section 207 and a connecting section 208, the screwing part can be accommodated through the bearing section 207. After the first and second locking members are connected, the positioning frame 2 is pressed onto the positioning post, realizing a detachable connection between the positioning frame 2 and the housing 1.

[0038] Optionally, such as Figures 1-4 As shown, in this application, the housing 1 has a first positioning groove 101 formed at the position corresponding to the first mating groove 201, and a second positioning groove 102 formed at the position corresponding to the second mating groove 202. The accommodating space shape of the first positioning groove 101 and the second positioning groove 102 is adapted to the outer contour shape of the first mating groove 201 and the second mating groove 202. The first positioning post 103 is disposed in the first positioning groove 101, and the second positioning post 104 is disposed in the second positioning groove 102. The side wall of the first mating groove 201 has a first notch 203, and the side wall of the second mating groove 202 has a second notch 204.

[0039] By further forming a first positioning groove 101 and a second positioning groove 102 on the housing 1, the first mating groove 201 and the second mating groove 202 can be correspondingly accommodated, so that the first mating groove 201 is embedded in the first positioning groove 101 and the second mating groove 202 is embedded in the second positioning groove 102. This allows the positioning frame 2 to be initially limited when it is assembled with the housing 1, which facilitates subsequent installation.

[0040] Accordingly, since the first positioning post 103 and the second positioning post 104 in this application need to enter the first mating groove 201 and the second mating groove 202 respectively, and the first positioning post 103 is formed in the first positioning groove 101 and the second positioning post 104 is formed in the second positioning groove 102, in order to ensure the smooth assembly between the positioning frame 2 and the housing 1, the positioning frame 2 provided in this application has a first notch 203 on the side wall corresponding to the first mating groove 201 and a second notch 204 on the side wall corresponding to the second mating groove 202. Thus, the first positioning post 103 can smoothly enter the first mating groove 201 and the second positioning post 104 can smoothly enter the second mating groove 202 through the first notch 203 and the second notch 204, thus ensuring the smooth assembly between the positioning frame 2 and the housing 1.

[0041] It is understood that in this application, both the first positioning groove 101 and the second positioning groove 102 are C-shaped, so that the first mating groove 201 and the second mating groove 202 can enter from the opening side of the first positioning groove 101 and the second positioning groove 102. Correspondingly, in this application, the first notch 203 and the second notch 204 are formed opposite to each other on the side of the first mating groove 201 and the second mating groove 202 away from the opening side.

[0042] Optionally, such as Figure 3 As shown, a first connecting portion is formed between the first positioning groove 101 and the first positioning post 103 in this application, and a second connecting portion is formed between the second positioning groove 102 and the second positioning post 104. The first notch 203 is provided corresponding to the first connecting portion, and the second notch 204 is provided corresponding to the second connecting portion.

[0043] In this application, both the first connecting portion and the second connecting portion extend along the axial direction of the first positioning post 103 and the second positioning post 104, thereby ensuring smooth insertion between the first notch portion 203 and the second notch portion 204 and the first connecting portion and the second connecting portion.

[0044] By providing the first connecting part and the second connecting part, the first positioning post 103 and the second positioning post 104 are not suspended in the first positioning groove 101 and the second positioning groove 102, thereby ensuring the stability of the first positioning post 103 and the second positioning post 104 and thus ensuring the installation accuracy.

[0045] The portable fascia gun provided in this application also includes a motor 8. The positioning frame 2 has a through hole and a limiting protrusion 209 at the position corresponding to the output shaft of the motor 8. The output shaft of the motor 8 passes through the limiting protrusion 209 and the through hole. The limiting protrusion 209 is located between the positioning frame 2 and the housing of the motor 8, and the end of the limiting protrusion 209 away from the positioning frame 2 abuts against the housing of the motor 8.

[0046] The motor 8 can provide stable power output for the fascia gun. However, since the motor 8 will generate a certain degree of vibration after starting, this application forms a through hole and a limiting protrusion 209 at the position of the positioning frame 2 corresponding to the output shaft of the motor 8. The through hole allows the output shaft to pass through, while the limiting protrusion 209 enables contact between the positioning frame 2 and the housing of the motor 8, thereby limiting the position of the motor 8 and reducing the problem of the motor 8's position shifting or changing due to vibration to a certain extent.

[0047] It is understandable that, such as Figure 4As shown, the present application also includes an eccentric wheel 3, a connecting rod 4, a piston 5, and a massage head 6; the eccentric wheel 3 is connected to the output shaft, one end of the connecting rod 4 is rotatably connected to the eccentric wheel 3, and the other end is rotatably connected to one end of the piston 5, and one end of the massage head 6 is connected to the other end of the piston 5.

[0048] The motor 8 drives the eccentric circuit to rotate, which in turn drives the connecting rod 4 to swing. This, in turn, drives the piston 5 to reciprocate in a linear direction. Since one end of the massage head 6 is connected to the piston 5, the reciprocating motion of the piston 5 in a linear direction can drive the massage head 6 to reciprocate in a linear direction, thereby realizing the massage function of the fascia gun.

[0049] Preferably, such as Figure 5 As shown, in this application, one end of the piston 5 forms a connecting platform 501 and a connecting post, and the other end forms a threaded hole 502. One end of the massage head 6 forms a screw 601, and the massage head 6 is threadedly connected to the threaded hole 502. The connecting post is formed on the connecting platform 501 and extends in the vertical direction. The end of the connecting rod 4 away from the eccentric wheel 3 is rotatably connected to the connecting post.

[0050] By using a threaded connection between the massage head 6 and the piston 5, the two can be connected separately. This separate connection allows the materials and colors of the massage head 6 to differ from those of the piston 5. To ensure the strength of the piston 5, it needs to be made of metal, while the massage head 6, which comes into contact with human skin, needs to be made of a softer, more skin-friendly material. Therefore, the threaded connection allows for more flexible material selection for the massage head 6, no longer limited by the piston 5, thereby improving the overall flexibility of the fascia gun.

[0051] It should be noted that the piston 5 and massage head 6 provided in this application can be detachably connected by thread before leaving the factory. After assembly, the massage head 6 and piston 5 can be fixedly connected by welding or other means to avoid loosening or detachment during use.

[0052] like Figure 6 As shown, the portable fascia gun provided in this application also includes multiple replacement heads 7, which are detachably connected to the massage head 6.

[0053] The replacement head 7 in this application can be made of silicone or plastic material and can be directly fitted onto the massage head 6. Alternatively, a threaded connection can be used to achieve a detachable connection between the replacement head 7 and the massage head 6, thereby providing users with corresponding massage methods according to their different needs.

[0054] Optionally, such as Figure 4As shown, the portable fascia gun provided in this application also includes a control board 10, a button, and a battery 9. The battery 9 is connected to the control board 10 by wiring, the motor 8 is connected to the control board 10 by wiring, and the button is connected to the control board 10 by wiring. The button is used to start and stop the motor 8, and the battery 9 provides power to the motor 8.

[0055] It is understood that the control board 10 mentioned above in this application is a PCB. The button is pressed to start and stop the motor 8. Of course, the existing program can also be used to implement a multi-level design, thereby providing more massage modes to meet user needs.

[0056] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
