Description

Technical Field

[0001] The invention relates to the technical field of fascia guns, in particular to a fascia gun capable of beating, massaging and kneading. Background Art

[0002] The fascia gun is also called a deep myofascial impactor or a massage gun. The fascia gun is equipped with a high-speed motor inside. The high-speed motor can drive the massage head to produce high-frequency vibrations. The high-frequency vibrations can act on the deep layer of the muscles to reduce local tissue tension, relieve pain, and promote blood circulation.

[0003] The gun head of the fascia gun is generally made of hard rubber, which transmits a strong vibration to the user. Although it can perform beating and massage on the human body, it is also easy to cause pain to the user, affecting the user's experience. There is a utility model patent published on February 18, 2025, with a fascia gun with announcement number CN222488066U. A conical groove is set on the massage surface to reduce the contact area between the massage surface and the human body. When working, the conical groove can wrap the air to impact the human body, just like a hollow palm slapping massage, which can improve the comfort and effect of the massage, thereby improving the user's experience.

[0004] The above-mentioned fascia gun reduces the impact force to a certain extent, but the overall force is still too strong, and there is no light kneading function, and it is impossible to choose between light kneading massage and heavy beating massage according to the needs of different people.

[0027] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention.

[0028] Such as Figures 1-3As shown in the figure, the present invention provides a fascia gun capable of pounding massage and kneading, including a housing 1 (the housing 1 includes a symmetrical first outer shell and a second outer shell, which are fixed by screws, facilitating the assembly, maintenance and replacement of internal parts). A driving member 2 is provided inside the housing 1. The driving member 2 is in transmission connection with a transmission member 3. The transmission member 3 has a first transmission portion 31 and a second transmission portion 32. The fascia gun further includes a first massage head 15, a second massage head 16, a first transmission mechanism 4 and a second transmission mechanism 5;

[0029] The first transmission mechanism 4 is connected between the first massage head 15 and the first transmission portion 31;

[0030] The second transmission mechanism 5 is connected between the second massage head 16 and the second transmission portion 32;

[0031] Wherein, when the driving member 2 drives the transmission member 3 to move, the first transmission mechanism 4 drives the first massage head 15 to reciprocate in a direction perpendicular to the human body part, and / or the second transmission mechanism 5 drives the second massage head 16 to rotate along the human body part;

[0032] When people need to perform mild kneading massage, the part of the human body to be massaged is closely attached to the second massage head 16. By starting the driving member 2 to drive the transmission member 3 to move, the transmission member 3 drives the second transmission mechanism 5 to move, so that the second massage head 16 rotates to perform mild kneading massage on the human body. On the contrary, when people need severe pounding massage, the part of the human body to be massaged is closely attached to the first massage head 15. By starting the driving member 2 to drive the transmission member 3 to move, the transmission member 3 drives the first transmission mechanism 4 to move, so that the first massage head 15 performs severe reciprocating pounding massage on the human body. Thus, people can choose the required massage method according to their own needs, and the applicability is stronger.

[0033] As Figure 2 and Figure 3 shown in the figure, the driving member 2 is a motor, and the transmission member 3 is a rotating shaft (at this time, the first transmission portion 31 and the second transmission portion 32 are integrally formed to form the rotating shaft). The output end of the motor is fixedly connected to the rotating shaft. The first transmission mechanism 4 includes a first eccentric block 41, a pull rod 42 and a movable column 43. The movable column 43 movably penetrates through the housing 1. The first eccentric block 41 is fixedly arranged on the outer surface of the rotating shaft. The first eccentric block 41 is in transmission connection with the pull rod 42 through a bearing. One end of the pull rod 42 is fixedly connected to the movable column 43. One end of the movable column 43 is fixedly connected to the first massage head 15 (here, the first massage head 15 is detachably fixed to one end of the movable column 43, such as by using a threaded connection or a clamping connection and other fixing methods, so as to facilitate the replacement of the first massage head 15);

[0034] The drive motor drives the rotation of the rotating shaft, and the rotating shaft drives the rotation of the first eccentric block 41. As a result, the first eccentric block 41 drives the pull rod 42 to swing reciprocally. The pull rod 42 pulls the movable column 43 to reciprocally penetrate the housing 1, thereby driving the first massage head 15 to perform reciprocating motion to achieve heavy pounding massage on the human body. This is the case when the fascia gun performs the pounding work. Compared with the existing technology, it will not be elaborated here.

[0035] As Figure 2 shown, a battery 9 is also provided in the housing 1. The battery 9 is electrically connected to the motor and used to supply power to the motor. This is not elaborated here compared with the existing technology.

[0036] As Figure 2 and Figure 3 shown, the second transmission mechanism 5 is a second eccentric block. One end of the rotating shaft is fixed with the second eccentric block, and a second massage head 16 is provided at one end of the second eccentric block;

[0037] When the drive motor drives the rotation of the rotating shaft, the rotating shaft drives the rotation of the second eccentric block, and the second eccentric block drives the second massage head 16 to rotate eccentrically. When the human body contacts the second massage head 16, the second massage head 16 rotates along the human body part for massage.

[0038] As Figure 2 and Figure 3 shown, a first one-way bearing 7 is provided between the first eccentric block 41 and the rotating shaft, and a second one-way bearing 8 is provided between the second eccentric block and the rotating shaft. The directions of the first one-way bearing 7 and the second one-way bearing 8 are the same or opposite;

[0039] Specifically, the housing 1 is L-shaped, having a horizontal section and a vertical section. The first massage head 15 is located at one end of the horizontal section, and the second massage head 16 is located at one end of the vertical section. Thus, the first massage head 15 and the second massage head 16 can move simultaneously to massage two people;

[0040] When the directions of the first one-way bearing 7 and the second one-way bearing 8 are the same, at this time, when the motor is driven to rotate the rotating shaft forward or backward, the rotating shaft drives the first eccentric block 41 and the second eccentric block to rotate simultaneously. While the first massage head 15 performs heavy pounding massage, the second massage head 16 performs mild kneading massage. When one person needs heavy massage and the other person needs mild massage among two people after adjusting the state and posture, two people can be massaged simultaneously, which is more convenient to use and makes the massage more efficient for two people. However, the pressure on the motor and the rotating shaft is relatively large at this time. At the same time, when only one person uses the fascia gun, it will cause waste;

[0041] When the directions of the first one-way bearing 7 and the second one-way bearing 8 are opposite, it can be set that when the rotating shaft is driven by the forward driving motor to rotate, the rotating shaft will drive the first one-way bearing 7 and the first eccentric block 41 to rotate, so as to realize the final heavy hammering massage work of the first massage head 15. At this time, the second one-way bearing 8 rotates idly and will not drive the second eccentric block to rotate, and the fascia gun only performs heavy hammering massage work;

[0042] When the reverse driving motor drives the rotating shaft to rotate, the rotating shaft will drive the second one-way bearing 8 and the second eccentric block to rotate, so as to realize the final gentle kneading massage work of the second massage head 16. At this time, the first one-way bearing 7 rotates idly and will not drive the first eccentric block 41 to rotate, and the fascia gun only performs gentle kneading massage work. By setting like this, when people use the fascia gun alone, they can separately select the massage method they need, and at this time, the pressure on the motor and the rotating shaft is relatively small.

[0043] Here, the material of the first eccentric block 41 is set as a metal material, and the material of the second eccentric block is a plastic material;

[0044] Since the first eccentric block 41 mainly drives the first massage head 15 to perform reciprocating impact hammering massage, the first eccentric block 41 is made of a metal material. Compared with a plastic material, its weight can be increased to achieve dynamic balance and play a certain shock-absorbing role. The second eccentric block only drives the second massage head 16 to perform relatively gentle kneading actions, so a plastic material can be used. Under the condition of meeting the normal use of the fascia gun, not only the cost is relatively low in this way, but also the whole fascia gun will not be too heavy.

[0045] As Figure 3 shown, it further includes a limiting component 11. The limiting component 11 includes a first snap ring 111 and a second snap ring 112 embedded on the rotating shaft (specifically, a first shaft groove and a second shaft groove are opened on the rotating shaft to accommodate part of the first snap ring 111 and the second snap ring 112). The bottom surface of the second snap ring 112 abuts against the top surface of the first eccentric block 41, and the top surface of the first snap ring 111 abuts against the bottom surface of the first one-way bearing 7 or the first eccentric block 41;

[0046] By setting the first snap ring 111 and the second snap ring 112, the first eccentric block 41 and the first one-way bearing 7 can be limited and fixed. Under continuous vibration and high-frequency impact, the first one-way bearing 7 may become loose. At this time, the first snap ring 111 and the second snap ring 112 serve as mechanical insurance to prevent the first one-way bearing 7 from detaching from the rotating shaft, thereby improving the durability of the product. In addition, the elasticity of the first snap ring 111 and the second snap ring 112 can slightly absorb the vibration energy transmitted by the rotating shaft, reduce noise and slow down the impact on the motor and the rotating shaft, and extend the service life. At the same time, when repairing or disassembling, the positions of the first snap ring 111 and the second snap ring 112 can be used as the disassembly reference for the first one-way bearing 7 and the first eccentric block 41 to help technicians quickly locate and reassemble.

[0047] As Figure 2 and Figure 3 shown, a boss 51 is provided on the top surface of the second eccentric block. The outer surface of the boss 51 fixes the turntable 6 through a bearing. The second massage head 16 is detachably fixed on the turntable 6 (specifically, the second massage head 16 can be fixed on the turntable 6 by screwing or snap connection, so as to facilitate the replacement of the second massage head 16).

[0048] By providing a bearing, when it is necessary to drive the second massage head 16 to perform massage and make the human body contact and press against the second massage head 16 relatively tightly, the turntable 6 and the second massage head 16 perform eccentric massage movements, but the turntable 6 and the second massage head 16 themselves do not rotate following the second eccentric block and the boss 51. Therefore, there is no need to overcome the resistance of the human body pressing on the second massage head 16 to limit its rotation following the second eccentric block and the boss 51, thereby relatively reducing the pressure on the second eccentric block and the rotating shaft, making the rotation of the second eccentric block and the rotating shaft smoother, and at the same time reducing the risk of damage to the second eccentric block made of plastic material.

[0049] As Figure 3 shown, the boss 51 has a small-area part and a large-area part. The bearing is provided on the outer surface of the small-area part and its bottom surface abuts against the top surface of the large-area part. A screw 13 is provided on the top surface of the boss 51, and the bottom surface of the nut of the screw 13 abuts against the top surface of the bearing on the outer surface of the boss 51.

[0050] When it is necessary to install the bearing and the turntable 6, place the bearing on the boss 51, and use the nut of the screw 13 to cooperate with the top surface of the large-area part of the boss 51 to limit and clamp the bearing for fixation, then the quick assembly of the turntable 6 and the bearing can be completed. Through the screw 13 and the bearing arranged in this way, when the turntable 6 or the bearing is damaged and needs to be replaced, only the screw 13 needs to be removed, and then the bearing and the turntable 6 can be taken out from the boss 51, so as to facilitate their quick replacement.

[0051] As Figure 2 and Figure 3 shown, a third circlip 12 is embedded on the rotating shaft (specifically, a third shaft groove is opened on the rotating shaft to accommodate part of the third circlip 12). The top surface of the third circlip 12 abuts against the bottom surface of the second one-way bearing 8 or the bottom surface of the second eccentric block. The top surface of the second eccentric block is located inside the housing 1.

[0052] The second eccentric block can be limited and fixed by the third circlip 12 and the housing 1. Under continuous vibration and high-frequency impact, the second one-way bearing 8 may become loose. At this time, the third circlip 12 serves as a mechanical insurance to prevent the second one-way bearing 8 from detaching from the rotating shaft, improving the durability of the product. In addition, the elasticity of the third circlip 12 can slightly absorb the vibration energy transmitted by the rotating shaft, reduce noise and mitigate the impact on the motor and the rotating shaft, extending the service life. At the same time, during maintenance or disassembly, the position of the third circlip 12 can be used as a disassembly reference for the second one-way bearing 8 and the second eccentric block, helping technicians quickly locate and reassemble.

[0053] As Figure 2 shown, a wear-resistant layer 14 (the material of the wear-resistant layer 14 here can be high-carbon chromium alloy steel or ceramics, etc.) is provided between the movable column 43 and the housing 1. Specifically, the wear-resistant layer 14 is fixed to the inner wall of the housing 1. By providing the wear-resistant layer 14, it is possible to prevent the movable column 43 from being directly contacted and damaged by friction with the housing 1 when moving in and out of the housing 1.
