[0044] Please refer to Figure 1 and Figure 2, an embodiment of the present utility model discloses a fascia gun. The fascia gun 100 includes a gun body 10, a driving assembly 11, and a massage mechanism 12. An accommodation cavity 101 is provided inside the gun body 10, and the gun body 10 includes a gun main body portion 102 and a holding portion 103. The holding portion 103 is connected to the gun main body portion 102 and is used for holding and has a holding axis O1. The holding portion 103 extends away from the gun main body portion 102 along the holding axis O1. At least part of the driving assembly 11 is disposed inside the accommodation cavity 101. The massage mechanism 12 includes a first massage head 121 and a second massage head 122 located outside the accommodation cavity 101. The first massage head 121 is connected to the driving assembly 11 and outputs a reciprocating motion along a first preset direction f1 under the drive of the driving assembly 11 to tap the human body. The second massage head 122 is connected to the driving assembly 11 and outputs a reciprocating motion along a second preset direction f2 under the drive of the driving assembly 11 to tap the human body. In other words, both the first massage head 121 and the second massage head 122 can perform a linear reciprocating motion under the drive of the driving assembly 11 to impact the massage part of the human body, thereby realizing the massage of the massage part of the human body.

[0045] In the present application, as Figure 1 shown, the angle between the first preset direction f1 and the second preset direction f2 is θ1, that is, the angle between the movement direction of the first massage head 121 and the movement direction of the second massage head 122 is θ1. The angle between the first preset direction f1 and the holding axis O1 of the holding portion 103 is θ2, that is, the angle between the movement direction of the first massage head 121 and the holding axis O1 of the holding portion 103 is θ2. Among them, 80° < θ1 < 120°, 90° ≤ θ2 < 120°. Exemplarily, θ1 = 81°, 85°, 87°, 90°, 93°, 95°, 100°, 105°, 108°, 110°, 112°, 115°, 117°, or 119°, etc. θ2 = 90°, 92°, 93°, 95°, 98°, 100°, 102°, 105°, 108°, 110°, 112°, 115°, 117°, 118°, or 119°, etc.

[0046] The percussion massager 100 provided by the embodiments of the present application includes a first massage head 121 and a second massage head 122, and thus is also called a double-headed percussion massager. During actual use, the first massage head 121 is usually used to massage the front of the body and the legs, and the second massage head 122 is used to massage the back of the body, such as the waist. By making the angle between the movement direction of the first massage head 121 and the movement direction of the second massage head 122 greater than 80° and less than 120°, and making the angle between the movement direction of the first massage head 121 and the holding axis O1 of the holding part 103 greater than or equal to 90° and less than 120°, when the user holds the holding part 103 of the percussion massager 100 in a preset grasping direction, the first massage head 121 faces forward for massaging the front of the body, and the orientation of the second massage head 122 is the same as the orientation of the back of the hand. When the user wants to massage the back of the body, the arm is extended backward, the shoulder joint is internally rotated and the elbow is flexed so that the back of the hand faces the lumbar and dorsal regions. At this time, the second massage head 122 faces the lumbar and dorsal regions, and the user can move the hand to use the second massage head 122 to massage the lumbar and dorsal regions. This posture conforms to ergonomics and will not make the user feel uncomfortable. Thus, by using the percussion massager 100 provided by the present application, when the user massages from the front of the body to the back, it is not necessary to readjust the grasping direction of the percussion massager 100, which is convenient for the user not to adjust the grasping direction when self-massaging the lumbar and dorsal regions, improves the use convenience, and makes the arm at a natural and comfortable angle, improving the comfort of the user during use.

[0047] Among them, "at least part of the driving component 11 is disposed in the accommodating cavity 101" can be understood as: part of the driving component 11 is disposed in the accommodating cavity 101, and the other part of the driving component 11 is disposed outside the accommodating cavity 101. At this time, the driving component 11 located outside the accommodating cavity 101 is connected to the first massage head 121 and the second massage head 122; or, the entire driving component 11 is located in the accommodating cavity 101. At this time, the first massage head 121 and the second massage head 122 located outside the accommodating cavity 101 can respectively extend into the accommodating cavity 101 to be connected to the driving component 11.

[0048] Exemplarily, such as Figure 1 and Figure 2As shown, the gun main body 102 may include a first gun body part 1021 and a second gun body part 1022 that are angularly connected. The first gun body part 1021 extends along a first preset direction f1 from its connection with the second gun body part 1022. The first massage head 121 is located at one end of the first gun body part 1021 away from the second gun body part 1022. The second gun body part 1022 extends along a second preset direction f2 from its connection with the first gun body part 1021. The holding part 103 is connected to the first gun body part 1021 and / or the second gun body part 1022, that is, the holding part 103 may be only connected to the first gun body part 1021, or the holding part 103 may be only connected to the second gun body part 1022, or the holding part 103 is connected to the connection between the first gun body part 1021 and the second gun body part 1022.

[0049] In some alternative embodiments, the accommodation cavity 101 may be jointly formed by the inner cavity of the first gun body part 1021 and the inner cavity of the second gun body 10. In some other alternative embodiments, the accommodation cavity 101 may be jointly formed by the inner cavity of the first gun body part 1021, the inner cavity of the second gun body part 1022, and the inner cavity of the holding part 103.

[0050] In the present application, as Figure 3 and Figure 4 shown, the first massage head 121 has a first massage surface 1211, and the second massage head 122 has a second massage surface 1221. It can be understood that when the fascia gun 100 in the present application is working, it knocks or impacts the massage part of the human body through the first massage head 121 or the second massage head 122. Then, the surface of the first massage head 121 for contacting the human body is the first massage surface 1211, and the surface of the second massage head 122 for contacting the human body is the second massage surface 1221.

[0051] For the convenience of description, in the present application, the maximum distance between the holding axis O1 of the holding part 103 and the first massage surface 1211 along the first preset direction f1 is defined as a, and at the same time, the maximum distance between the holding axis O1 of the holding part 103 and the second massage surface 1221 along the second preset direction f2 is defined as b. It can be understood that the above definitions are only examples for the convenience of description and understanding, and do not limit the protection scope of this embodiment.

[0052] In some alternative embodiments, b < a. Generally, the first massage head 121 is used to massage the limb parts on the front of the body, while the second massage head 122 is used to massage the limb parts on the back of the body by the user lifting the arm backward. Therefore, the area that the second massage head 122 can massage is limited, while the area that the first massage head 121 can massage is usually relatively larger. By satisfying the above relationship, it can ensure that the massage surface of the first massage head 121 is at a sufficient distance from the holding part 103, so as to reduce the movement distance of the hand when the user massages the distal limb on the front of the body, facilitating the user to massage the distal limb on the front of the body, and thus facilitating the user to use.

[0053] Optionally, b < 110 mm. For example, b = 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 65 mm, 70 mm, 75 mm, 80 mm, 85 mm, 90 mm, 95 mm, 100 mm, 105 mm or 109 mm, etc. Herein, "mm" represents millimeter. By making the maximum distance between the holding axis O1 of the holding part 103 and the second massage surface 1221 less than 110 mm, when massaging the back of the body, such as massaging the waist and back, the angle at which the user's arm is lifted backward can be relatively small, enabling the user's arm to massage the waist and back in a comfortable position, and thus being beneficial to improving the user's comfort when massaging the waist and back.

[0054] In some alternative embodiments, the movement stroke of the first massage head 121 in the first preset direction f1 is greater than the movement stroke of the second massage head 122 in the second preset direction f2, that is, the movement strokes of the first massage head 121 and the second massage head 122 are different. In this way, different massage depths can be provided to offer massages with different intensities. Moreover, since the first massage head 121 is usually used to massage the front of the body and the legs, and the muscle thickness of these parts is relatively large, a greater massage depth is required. The first massage head 121 with a relatively larger movement stroke can provide a greater-intensity massage when massaging the front of the body and the legs, increasing the massage depth to ensure the massage effect of the first massage head 121.

[0055] Exemplarily, the movement stroke of the second massage head 122 along the second preset direction f2 is not greater than 12 mm, that is, the movement stroke of the second massage head 122 along the second preset direction f2 is less than or equal to 12 mm. For example, the movement stroke of the second massage head 122 along the second preset direction f2 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 5.5 mm, 6 mm, 6.5 mm, 7 mm, 7.5 mm, 8 mm, 8.5 mm, 9 mm, 9.5 mm, 10 mm, 10.5 mm, 11 mm, 11.5 mm or 12 mm, etc. Since the second massage head 122 usually massages the waist and back by the user lifting the arm backward, in the posture of extending the arm backward, rotating the shoulder joint inward and flexing the elbow, the force that the user can use is small. If the amplitude is too large, it will increase the difficulty of massaging the waist and back. And the muscle thickness of the waist and back is relatively thin and does not require too much massage depth. Therefore, by limiting the movement stroke of the second massage head 122 not to exceed 12 mm, the amplitude of the second massage head 122 is reduced, thereby reducing the difficulty of the second massage head 122 massaging the waist and back. At the same time, it is avoided to apply too much massage force to the waist and back with relatively thin muscles, so as to ensure that the second massage head 122 can take into account both good massage effect and massage comfort.

[0056] In some embodiments, as shown in combination with Figures 5 to 7 The driving assembly 11 includes a power component 111, a balance disk 112, a first transmission mechanism 113 and a second transmission mechanism 114 located in the accommodation cavity 101. The power component 111 is arranged in the accommodation cavity 101. The axis of the balance disk 112 is connected to the power component 111. The first transmission mechanism 113 is eccentrically and rotatably connected to the balance disk 112. The second transmission mechanism 114 is eccentrically and rotatably connected to the balance disk 112. Among them, the first massage head 121 is connected to the first transmission mechanism 113, and the second massage head 122 is connected to the second transmission mechanism 114. The power component 111 drives the first massage head 121 to reciprocate along the first preset direction f1 through the first transmission mechanism 113 to massage the human body, and also drives the second massage head 122 to reciprocate along the second preset direction f2 through the second transmission mechanism 114 to massage the human body. Among them, the power component 111 can be a motor, and the output shaft of the motor can be inserted into the axis hole of the balance disk 112.

[0057] Through the above structural design, a power component 111 can provide power for two massage heads (that is, the first massage head 121 and the second massage head 122) to drive the two massage heads to reciprocate. In this way, the use of the power component 111 can be reduced, not only the structure of the driving assembly 11 is relatively compact, the volume of the driving assembly 11 is reduced, which is beneficial to the miniaturization of the fascia gun 100; at the same time, the cost can also be reduced.

[0058] Optionally, the connection between the first massage head 121 and the first transmission mechanism 113 in this application can be a detachable connection. For example, the first massage head 121 can be connected to the first transmission mechanism 113 by at least one of the connection methods of screw connection, snap connection, and magnetic attraction connection. Similarly, the connection between the second massage head 122 and the second transmission mechanism 114 can also be a detachable connection. For example, the second massage head 122 can be connected to the second transmission mechanism 114 by at least one of the connection methods of screw connection, snap connection, and magnetic attraction connection. Designing the first massage head 121 and the second massage head 122 as detachable massage heads, when the first massage head 121 and / or the second massage head 122 is damaged and needs to be replaced, there is no need to replace the entire fascia gun 100 so that the fascia gun 100 can continue to be used. Instead, just replace the damaged massage head with a new one. This is beneficial to reducing the replacement cost of the fascia gun 100.

[0059] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 shown, the fascia gun 100 further includes a mounting bracket 13. The mounting bracket 13 is installed in the accommodation cavity 101, and the driving assembly 11 is installed on the mounting bracket 13 to be installed in the accommodation cavity 101. That is, the power component 111, the balance disk 112, the first transmission mechanism 113, and the second transmission mechanism 114 are installed in the accommodation cavity 101 through the mounting bracket 13. Among them, the second transmission mechanism 114 has a connection position M connected to the power component 111 and a first end face 114a facing away from the power component 111. In the second preset direction f2, the distance between the connection position M and the first end face 114a is c, and c > 40 mm. For example, c = 41 mm, 44 mm, 45 mm, 48 mm, 50 mm, 55 mm, 58 mm, 60 mm, 63 mm, 65 mm, 68 mm, or 70 mm, etc. By satisfying the above relational expression, a position for setting the screw hole 131 can be left at the part of the mounting bracket 13 located between the second eccentric shaft 1122 and the first end face, so that the mounting bracket 13 can be fixedly installed in the accommodation cavity 101 through the screw hole 131, which is beneficial to ensuring the connection strength between the mounting bracket 13 and the accommodation cavity 101 and reducing the vibration of the gun body 10.

[0060] Optionally, both the first transmission mechanism 113 and the second transmission mechanism 114 can be link mechanisms, such as a crank-slider mechanism or a cam-link mechanism, etc.

[0061] In some alternative embodiments, in combination with Figure 7 and Figure 8As shown, the first transmission mechanism 113 may include a first swing arm 1131, a first sleeve 1132 and a first guide sleeve 1133.

The second eccentric shaft 1122 is provided on the first eccentric shaft 1121. On the one hand, it can make the structure of the balance disk 112 relatively simple; on the other hand, since if the second eccentric shaft 1122 is separately provided on the balance disk 112 from the first eccentric shaft 1121, it will play a role in dispersing the driving force. Therefore, the second eccentric shaft 1122 is provided on the first eccentric shaft 1121, which can increase the centrifugal force to enhance the impact force.

And because the first massage head 121 is usually used to massage the front of the body and the legs, and the muscles in these parts are thicker and require a deeper massage depth, the first massage head 121 with a relatively larger movement stroke can provide a stronger massage when massaging the front of the body and the legs, and increase the massage depth to ensure the massage effect of the first massage head 121.

The second transmission mechanism 114 further includes a fourth anti-slip component (not shown). The two ends of the fourth anti-slip component are respectively mounted on the seventh mounting portion 1122a and the eighth mounting portion 1141d, so that the fourth anti-slip component can be used to abut against the fourth bearing 116 to prevent the fourth bearing 116 from being separated from the second eccentric shaft 1122 and the fourth axial hole 1141c. This ensures the connection strength between the second eccentric shaft 1122 and the second swing arm 1141, stabilizes the power transmission from the power component 111 to the second massage head 122, and avoids the situation where the force between the second eccentric shaft 1122 and the second swing arm 1141 is unbalanced due to the fourth bearing 116 being separated, thereby reducing unnecessary vibration.
