Description

Technical Field

[0001] This invention relates to the field of fascia gun technology, and in particular to a fascia gun that can be used for pounding, massaging and kneading. Background Technology

[0002] Fascia guns, also known as deep myofascial impactors or massage guns, are equipped with a high-speed motor inside. This motor drives the massage head to generate high-frequency vibrations, which can act on the deep layers of muscles to reduce local tissue tension, relieve pain, and promote blood circulation.

[0003] The nozzles of fascia guns are generally made of hard rubber, which transmits strong vibrations to users. Although they can massage the body, they can also easily cause pain and affect the user experience. A utility model patent published on February 18, 2025, with the publication number CN222488066U, describes a fascia gun that reduces the contact area between the massage surface and the body by setting a conical groove on the massage surface. When working, the conical groove can trap air to impact the body, similar to a hollow hand patting and massaging, which can improve the comfort and effect of the massage, thereby improving the user experience.

[0004] The aforementioned fascia gun reduces the impact and pounding force to some extent, but the overall force is still too strong. It lacks a gentle kneading function and cannot select between gentle kneading massage and heavy pounding massage according to different people's needs. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the present invention provides a fascia gun that can be used for percussion massage and kneading, so as to solve the problem that the existing fascia guns only have the function of impact percussion massage, and cannot perform gentle kneading massage according to the different needs of people, resulting in poor applicability.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fascia gun capable of tapping, massaging, and kneading, comprising a housing, wherein a driving component is disposed within the housing, the driving component is pulsatorically connected to a transmission component, the transmission component having a first transmission part and a second transmission part, and the fascia gun further comprising:

[0007] First massage head;

[0008] Second massage head;

[0009] A first transmission mechanism is connected between the first massage head and the first transmission part;

[0010] The second transmission mechanism is connected between the second massage head and the second transmission part;

[0011] When the driving component drives the transmission component to move, the first transmission mechanism drives the first massage head to reciprocate along a direction perpendicular to the human body part, and / or the second transmission mechanism drives the second massage head to rotate along the human body part.

[0012] Preferably, the driving component is a motor, the transmission component is a rotating shaft, the output end of the motor is fixedly connected to the rotating shaft, the first transmission mechanism includes a first eccentric block, a pull rod and a movable column, the movable column movably penetrates the housing, the first eccentric block is fixed on the outer surface of the rotating shaft, the first eccentric block is connected to the pull rod through a bearing, one end of the pull rod is fixedly connected to the movable column, and one end of the movable column is fixed to the first massage head.

[0013] Preferably, the second transmission mechanism is a second eccentric block, one end of the rotating shaft is fixed to the second eccentric block, and one end of the second eccentric block is provided with a second massage head.

[0014] Preferably, a first one-way bearing is provided between the first eccentric block and the rotating shaft, and a second one-way bearing is provided between the second eccentric block and the rotating shaft, wherein the first one-way bearing and the second one-way bearing are in the same or opposite directions.

[0015] Preferably, the first eccentric block is made of metal, and the second eccentric block is made of plastic.

[0016] Preferably, it also includes a limiting component, which includes a first retaining ring and a second retaining ring embedded on the rotating shaft, the bottom surface of the second retaining ring abutting against the top surface of the first eccentric block, and the top surface of the first retaining ring abutting against the first one-way bearing or the bottom surface of the first eccentric block.

[0017] Preferably, the top surface of the second eccentric block is provided with a boss, and the outer surface of the boss is fixed to the turntable by a bearing, and the second massage head is detachably fixed to the turntable.

[0018] Preferably, the boss has a small area portion and a large area portion, the bearing is disposed on the outer surface of the small area portion and its bottom surface abuts against the top surface of the large area portion, the top surface of the boss is provided with a screw, and the bottom surface of the screw nut abuts against the top surface of the bearing on the outer surface of the boss.

[0019] Preferably, a third retaining ring is embedded in the rotating shaft, and the top surface of the third retaining ring abuts against the bottom surface of the second one-way bearing or the bottom surface of the second eccentric block, the top surface of the second eccentric block being located inside the housing.

[0020] Preferably, the housing is L-shaped, having a horizontal section and a vertical section, with the first massage head located at one end of the horizontal section and the second massage head located at one end of the vertical section.

[0021] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0022] When a person needs a light kneading massage, the area of ​​the body to be massaged is placed close to the second massage head.

Conversely, when a person needs a heavy percussion massage, the area of ​​the body to be massaged is placed close to the first massage head. The drive mechanism moves the transmission mechanism, which in turn moves the first transmission mechanism, causing the first massage head to perform a heavy, reciprocating percussion massage. Thus, people can choose the massage method they need according to their own requirements, making it more versatile. Attached Figure Description

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention is further described below in conjunction with specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this invention.

[0028] like Figures 1-3As shown, the present invention provides a fascia gun that can be used for pounding, massaging 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 to facilitate the assembly, inspection and replacement of internal parts), a drive component 2 is provided inside the housing 1, the drive component 2 is connected to a transmission component 3, the transmission component 3 has a first transmission part 31 and a second transmission part 32, and the fascia gun also 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 part 31;

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

[0031] When the driving component 2 drives the transmission component 3 to move, the first transmission mechanism 4 drives the first massage head 15 to reciprocate along 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 a person needs a light kneading massage, the area of ​​the body to be massaged is placed close to the second massage head 16. The drive component 2 drives the transmission component 3 to move, and the transmission component 3 drives the second transmission mechanism 5 to move, causing the second massage head 16 to rotate and perform a light kneading massage on the body. Conversely, when a person needs a heavy percussion massage, the area of ​​the body to be massaged is placed close to the first massage head 15. The drive component 2 drives the transmission component 3 to move, and the transmission component 3 drives the first transmission mechanism 4 to move, causing the first massage head 15 to perform a heavy reciprocating percussion massage on the body. Thus, people can choose the massage method they need according to their own needs, making it more applicable.

[0033] like Figure 2 and Figure 3 As shown, the driving component 2 is a motor, and the transmission component 3 is a rotating shaft (at this time, the first transmission part 31 and the second transmission part 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 the housing 1. The first eccentric block 41 is fixed on the outer surface of the rotating shaft. The first eccentric block 41 is connected to 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 fixed to the first massage head 15 (here, the first massage head 15 is detachably fixed to one end of the movable column 43. For example, a threaded connection or a snap-fit ​​connection can be used to fix it, so as to facilitate the replacement of the first massage head 15).

[0034] The drive motor drives the rotating shaft to rotate, which in turn drives the first eccentric block 41 to rotate. The first eccentric block 41 then drives the pull rod 42 to swing back and forth. The pull rod 42 pulls the movable column 43 to move back and forth through the housing 1, thereby driving the first massage head 15 to reciprocate, so as to achieve heavy-duty percussion massage of the human body. This is the percussion work of the fascia gun. Compared with the existing technology, it will not be described in detail here.

[0035] like Figure 2 As shown, a battery 9 is also provided inside the housing 1. The battery 9 is electrically connected to the motor to supply power to the motor. This is relative to the existing technology and will not be described in detail here.

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

[0037] When the drive motor drives the rotating shaft to rotate, the rotating shaft drives the second eccentric block to rotate, and the second eccentric block drives the second massage head 16 to rotate eccentrically. When the human body comes into contact with the second massage head 16, the second massage head 16 rotates and massages along the human body parts.

[0038] like Figure 2 and Figure 3 As 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, with 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, so that the first massage head 15 and the second massage head 16 can move simultaneously to massage two people.

[0040] When the first one-way bearing 7 and the second one-way bearing 8 are in the same direction, the rotating shaft is driven to rotate by starting the motor in the forward or reverse direction. The rotating shaft drives the first eccentric block 41 and the second eccentric block to rotate simultaneously. This allows the first massage head 15 to perform a heavy hammering massage while the second massage head 16 performs a light kneading massage. With the settings and postures adjusted, if one person needs a heavy massage and the other needs a light massage, both people can be massaged at the same time, making it more convenient to use and more efficient. However, the pressure on the motor and the rotating bearing is relatively high at this time. Also, it will be wasteful if only one person uses the fascia gun.

[0041] When the first one-way bearing 7 and the second one-way bearing 8 are in opposite directions, it can be set that when the rotating shaft is driven to rotate by the forward start motor, the rotating shaft will drive the first one-way bearing 7 and the first eccentric block 41 to rotate, thereby realizing the final heavy-duty percussion massage 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. The fascia gun only performs heavy-duty percussion massage.

[0042] When the reverse-starting 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, thereby realizing the final light kneading massage 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. The fascia gun only performs light kneading massage. With this setting, when people use the fascia gun alone, they can choose the massage mode they need. At this time, the pressure on the motor and the rotating bearing is relatively small.

[0043] Here, the material of the first eccentric block 41 is set to metal, and the material of the second eccentric block is set to plastic.

[0044] Since the first eccentric block 41 mainly drives the first massage head 15 to perform reciprocating impact and pounding massage, the first eccentric block 41 is made of metal, which increases its weight compared to plastic, so as to achieve dynamic balance and play a certain role in shock absorption. The second eccentric block only drives the second massage head 16 to perform relatively gentle kneading action, so it can be made of plastic. Under the condition of meeting the normal use of the fascia gun, this not only keeps the cost relatively low, but also prevents the fascia gun from being too heavy.

[0045] like Figure 3 As shown, it also includes a limiting component 11, which includes a first retaining ring 111 and a second retaining 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 retaining ring 111 and the second retaining ring 112). The bottom surface of the second retaining ring 112 abuts against the top surface of the first eccentric block 41, and the top surface of the first retaining ring 111 abuts against the first one-way bearing 7 or the bottom surface of the first eccentric block 41.

[0046] By setting the first retaining ring 111 and the second retaining 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 loosen. At this time, the first retaining ring 111 and the second retaining ring 112 act as mechanical safety to prevent the first one-way bearing 7 from detaching from the shaft, thereby improving product durability. In addition, the elasticity of the first retaining ring 111 and the second retaining ring 112 can slightly absorb the vibration energy transmitted by the shaft, reduce noise and slow down the impact on the motor and shaft, and extend service life. At the same time, during maintenance or disassembly, the position of the first retaining ring 111 and the second retaining ring 112 can serve as the disassembly reference for the first one-way bearing 7 and the first eccentric block 41, helping technicians to quickly locate and reassemble them.

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

[0048] By setting bearings, when the second massage head 16 needs to be driven to perform massage, and the human body comes into contact with the second massage head 16 and presses against it, the turntable 6 and the second massage head 16 perform eccentric massage movements. However, the turntable 6 and the second massage head 16 themselves do not rotate with the second eccentric block and the boss 51. Therefore, it is not necessary to overcome the resistance of the human body pressing on the second massage head 16 to restrict it from rotating with the second eccentric block and the boss 51. This relatively reduces the pressure on the second eccentric block and the rotating shaft, making the rotation of the second eccentric block and the rotating shaft smoother. At the same time, it can reduce the risk of damage to the plastic second eccentric block.

[0049] like Figure 3 As shown, the boss 51 has a small area and a large area. The bearing is located on the outer surface of the small area and its bottom surface abuts against the top surface of the large area. The top surface of the boss 51 is provided with a screw 13, 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 turntable 6, place the bearing on the boss 51, and use the nut of the screw 13 to lock and clamp the bearing with the large area of ​​the top surface of the boss 51 to complete the quick assembly of the turntable 6 and the bearing. With the screw 13 and bearing set in this way, when the turntable 6 or the bearing is damaged and needs to be replaced, simply remove the screw 13 to remove the bearing and the turntable 6 from the boss 51, so as to facilitate quick replacement.

[0051] like Figure 2 and Figure 3 As shown, a third retaining ring 12 is embedded in the rotating shaft (specifically, a third shaft groove is opened on the rotating shaft to accommodate part of the third retaining ring 12). The top surface of the third retaining ring 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 retaining ring 12 and the housing 1. Under continuous vibration and high-frequency impact, the second one-way bearing 8 may loosen. At this time, the third retaining ring 12 acts as a mechanical safety to prevent the second one-way bearing 8 from detaching from the shaft, thereby improving product durability. In addition, the elasticity of the third retaining ring 12 can slightly absorb the vibration energy transmitted by the shaft, reduce noise and slow down the impact on the motor and shaft, and extend service life. At the same time, during maintenance or disassembly, the position of the third retaining ring 12 can serve as a disassembly reference for the second one-way bearing 8 and the second eccentric block, helping technicians to quickly locate and reassemble them.

[0053] like Figure 2 Figure 3 As shown, a wear-resistant layer 14 is provided between the movable column 43 and the housing 1 (the material of the wear-resistant layer 14 can be high carbon chromium alloy steel or ceramic, etc.). Specifically, the wear-resistant layer 14 is fixed to the inner wall of the housing 1. By providing the wear-resistant layer 14, the movable column 43 is prevented from being damaged by direct contact and friction with the housing 1 when it moves in and out of the housing 1.
