Description

Technical Field

[0001] The present invention relates to the field of massagers, in particular to a massager and an installation method. Background Art

[0002] The fascia gun is an advanced massage tool that uses high-frequency vibrations to target receptors within muscles, tendons, and joint capsules, producing a significant massage effect. This tool can effectively relieve muscle-related pain, increase the body's pain tolerance threshold, and reduce the accumulation of lactic acid in muscles after exercise. Using a fascia gun after exercise is particularly beneficial, as it can quickly relieve muscle soreness and significantly shorten muscle recovery time, providing significant benefits for sports enthusiasts and fitness enthusiasts.

[0003] However, most common fascia guns currently available on the market use an integrated, integral structure that cannot be disassembled. This design has certain limitations during use. Because the muscle depth and massage requirements vary across different parts of the human body, the fixed length of the fascia gun cannot be flexibly adjusted according to the massage area. For example, when massaging thinner areas such as arms and legs, a longer fascia gun may be cumbersome and inconvenient to operate; while when massaging wider areas such as the back, the gun may not be long enough to achieve the desired massage effect. This non-adjustable design limits the use scenarios and applicable population of the fascia gun, and cannot meet the diverse needs of users in different scenarios. Summary of the Invention

[0046] Reference Figure 1-Figure 5 The basic embodiment of the first aspect of the present invention provides a massager, comprising:

[0047] The striking part 100 is provided with a first buckle 133 and a first button 131, and the first buckle 133 is deformable;

[0048] The curved extension portion 200 or the handle portion 300 is provided with a first slot 210 and is detachably mounted on the striking portion 100;

[0049] The first button 131 can press the first buckle 133 to deform it, and separate the first buckle 133 and the first slot 210;

[0050] The first button 131 can move away from the first buckle 133 , the first buckle 133 recovers its shape, and the first buckle 133 and the first slot 210 can be engaged with each other.

[0051] According to the embodiment of the present invention, by such setting, at least the following effects can be achieved:

[0052] The first button 131 controls the first buckle 133 and the first slot 210 to engage or disengage, so that the striking part 100 can be quickly installed and assembled;

[0053] The striking portion 100 can be connected to the curved extension portion 200 to increase the overall length of the massager, or can be directly connected via the handle portion 300;

[0054] It adopts a detachable mounting structure that adapts to multiple scenarios, perfectly meeting the massage needs of different body parts. Its long arm form is composed of a striking part 100, a curved extension part 200, and a handle part 300. The flexible adjustment function of the curved extension part 200 can accurately reach deep muscle groups such as the upper shoulder, the back of the waist and neck, the inner shoulder blade, and the paraspinal groove of the waist and back, effectively solving the pain points of hidden areas that traditional massagers cannot reach. The curved extension part 200 not only greatly extends the length of the massager to adapt to different user body shapes, but also avoids excessive twisting of the wrist during operation, providing a more comfortable and convenient user experience.

[0055] The compact design features a striking unit 100 directly connected to the handle 300, making it easy to operate with one hand. It's particularly suitable for quickly relaxing superficial muscles like the calves and forearms. Module assembly and disassembly require no tools, minimizing changeover time and easily meeting the needs of fragmented usage scenarios such as workout breaks and office breaks.

[0056] It should be noted that a driving mechanism is provided in the striking part 100. The specific driving mechanism includes a motor and a cam reciprocating motion structure. This is the existing structure of the fascia gun massager movement. It can be clearly seen from the accompanying drawings. The specific working principle will not be elaborated here.

[0057] Reference Figure 1-Figure 5 , based on the basic embodiment, the first embodiment of the first buckle, the first buckle 133 is a snap ring 136, the snap ring 136 is provided with a notch, and the snap ring 136 is provided on the striking part 100;

[0058] The first button 131 can be inserted into the notch of the snap ring 136 , causing the snap ring 136 to deform and increase its inner diameter, and the first buckle 133 and the first slot 210 to separate;

[0059] The first button 131 can be away from the notch of the snap ring 136 , the snap ring 136 recovers its shape and its inner diameter decreases, and the first buckle 133 is engaged with the first slot 210 .

[0060] Under this setting, the snap ring is fixed on the striking part, and the first button is movably provided on the striking part. Through the cooperation between the first button 131 and the snap ring 136, the snap ring 136 can be deformed so that the inner diameter increases, or the snap ring 136 can restore its shape and the inner diameter decreases, so that the first clamping groove 210 can be separated from or clamped with the first buckle 133; the cooperation between the snap ring and the first clamping groove is beneficial to the stability of the installation connection, and multiple first clamping grooves can be provided, and one snap ring can be connected to multiple clamping grooves respectively, thereby improving the stability of the installation; a connecting plane is provided on the snap ring, and the connecting plane and the first clamping groove are adapted to each other, which can increase the contact surface between the two and improve the stability of the installation.

[0061] It should be noted that the clamping ring 136 is made of elastic material or plastic. The elastic material has elastic recovery ability, and the plastic has deformation recovery ability when the deformation is small.

[0062] Furthermore, the notch of the snap ring 136 is provided with a first inclined surface 1311, and the side wall of the first button 131 is provided with a second inclined surface 1361, and the first inclined surface 1311 and the second inclined surface 1361 are adapted to each other. The mutually adapted inclined surfaces are conducive to the outward deformation of the snap ring 136.

[0063] Furthermore, a fixed end 1362 is provided on one side of the snap ring 136 away from the notch, and the fixed end 1362 is connected to the striking part 100. One end of the snap ring 136 is fixed, which is conducive to the snap ring 136 being deformed outward from the fixed end 1362 to both sides.

[0064] Based on the basic embodiment, in a second embodiment of the first buckle 133, one end of the first buckle 133 is fixedly connected to the striking part 100, and the other end can abut against the first button 131. The middle portion of the first buckle 133 can be separated from or engaged with the first engaging groove 210. When the first button 131 is actuated, the first button 131 can abut against the first buckle 133, causing the first buckle 133 to deform and move away from the first engaging groove 210, separating the first engaging groove 210 and the first buckle 133. When the first button 131 is not pressed, the first buckle 133 returns to its original shape, engaging the first engaging groove 210 and the first buckle 133. The structure can refer to the shape of the half-cut snap ring in the first embodiment.

[0065] Furthermore, the first buckle 133 is a rod-shaped or arc-shaped structure.

[0066] In some embodiments, the curved extension portion 200 is provided with a first slot 210, a second buckle 240, and a second button 250. The handle portion 300 is provided with a second slot 320. The handle portion 300 is detachably mounted to the curved extension portion 200. The second button 250 can engage or disengage the second buckle 240 and the second slot 320. The long-arm form assembly comprises the striking portion 100, the curved extension portion 200, and the handle portion 300. The flexible adjustment function of the curved extension portion 200 enables precise access to deep muscle groups such as the upper shoulder, the back of the waist and neck, the inner shoulder blades, and the paraspinal groove of the lumbar back, effectively addressing pain points that are difficult to reach with traditional massagers. The curved extension portion 200 not only significantly extends the length of the massager to accommodate different body shapes, but also prevents excessive wrist twisting during operation, providing a more comfortable and convenient user experience.

[0067] It should be noted that the first card slot 210 and the second card slot 320 have basically the same structure, and the first clip 133 and the second clip 240 have basically the same structure. Through different connection states, they are applicable to different parts and are easy to use.

[0068] In some embodiments, the curved extension 200 is provided with a second elastic return member 260. One end of the second elastic return member 260 is connected to the curved extension 200, and the other end is connected to the second button 250. The second elastic return member 260 drives the second button 250 through elastic force, thereby maintaining the engagement between the second buckle 240 and the second slot 320. The elastic return member can be a spring or a long strip of rubber. The elastic return member can maintain the position of the pressing portion in its original state, that is, the engaging portion remains engaged with the slot. When the user presses, the slot and buckle can be separated. When the user does not press, the elastic return member returns to its original position, allowing the engaging portion and slot to cooperate and maintain the engaged state, providing ease of use.

[0069] In some embodiments, the striking portion 100 is provided with a first elastic return member 134. One end of the first elastic return member 134 is connected to the striking portion 100, and the other end is connected to the first button 131. The first elastic return member 134 drives the first button 131 through elastic force, so that the first latch 133 and the first latching slot 210 remain in the engaged state. The same applies to the first elastic return member 134 and the second elastic return member 260.

[0070] In some embodiments, the striking portion 100 is provided with a through hole, through which the first button 131 passes, allowing a portion of the first button 131 to protrude. A portion of the pressing portion is exposed to the outside, allowing for quick installation and removal by adjusting the fit between the buckle and the slot by pressing the outer pressing portion.

[0071] In some embodiments, one of the handle portion 300 and the striking portion 100 is provided with a pin 120 and the other is provided with a socket 220 . The pin 120 can be inserted into the socket 220 to electrically connect the handle portion 300 and the striking portion 100 .

[0072] In some embodiments, one of the handle portion 300 and the striking portion 100 is provided with an insert 230 , and the other is provided with a slot 140 . The insert 230 can be inserted into the slot 140 , the pin 120 is provided in the slot 140 , and the socket 220 is provided in the insert 230 .

[0073] In some embodiments, the striking portion 100 is provided with a drive assembly and at least two striking members 110, and the drive assembly is capable of driving the striking members 110 to perform reciprocating motion. In terms of the striking head design, this massager adopts a multi-head synergistic design with a symmetrical layout. Through phase synchronization or alternating striking, the striking pressure is dispersed, effectively reducing local pressure and the risk of congestion caused by excessive muscle compression. For the common problem of unilateral back muscle tension in sedentary people, the dual heads are synchronously and symmetrically placed in symmetrical areas such as the waist and neck, which can help restore symmetry and promote the symmetrical restoration of muscle tension.

[0074] In addition, the effective area of ​​the multiple heads working together far exceeds that of a single head, which significantly improves the efficiency when treating large muscle groups such as the gluteus maximus and the back of the thigh. Compared with the single-click head, the double-click head has more force points, each of which is balanced with each other, and the structure is more stable. It will not shake or shift easily during use, ensuring the stability of the striking effect during the massage process, allowing users to more accurately control the massage force and position. The good stability of the double-click head provides a uniform and continuous massage effect, avoiding the fluctuation of force, and further improving the comfort and effect of the massage.

[0075] The combination of multiple striking heads and long arms allows the user to move the striking part 100 to a suitable position according to personal needs when using it alone without twisting the wrist. Through real-time sensory perception, the angle of the massager can be conveniently adjusted to balance the pressure of each striking head on the body, bringing better comfort to the user.

[0076] In some embodiments, the driving assembly can drive the plurality of striking members 110 to move toward or away from the striking part 100 body alternately or collectively.

[0077] Under this setting, there are two main modes, which can exist independently or switch between each other.

[0078] Alternating striking mode (motor drives cams at opposite angles):

[0079] The motor drives the dual heads in turn, which can maintain the amplitude and frequency stability of a single striking head, approaching the performance of a single-head fascia gun;

[0080] To reduce operational risks, users can adjust the position and pressure of each strike to avoid accidentally touching sensitive areas (such as the edge of the shoulder blade and cervical spine) at the same time;

[0081] Simulating the rhythm of manual massage, alternating vibrations are closer to the "press-relax" alternating technique of a physiotherapist, which may improve muscle adaptability.

[0082] Joint striking mode (double heads rotate synchronously at the same angle):

[0083] The coverage area is expanded, and the two heads act on adjacent areas (such as the erector spinae muscles on both sides of the spine) at the same time, saving time.

[0084] Symmetrical muscle groups are stimulated synchronously, which is suitable for treating bilaterally symmetrical parts (such as shoulders and buttocks) and can balance the tension on both sides.

[0085] In some embodiments, one of the handle 300 and the striking unit 100 is provided with a pin 120, and the other is provided with a socket 220. The pin 120 can be inserted into the socket 220 to electrically connect the handle 300 and the striking unit 100. The connection between the pin 120 and the socket 220 allows for quick power-up of the handle 300 and the striking unit 100.

[0086] In some embodiments, one of the handle portion 300 and the striking portion 100 is provided with an insert 230 , and the other is provided with a slot 140 . The insert 230 can be inserted into the slot 140 , the pin 120 is provided in the slot 140 , and the socket 220 is provided in the insert 230 .

[0087] In some embodiments, a first guide surface is provided on the circumferential side of the curved extension portion 200 or the handle portion 300, and a second guide surface is provided on the inner wall of the striking portion 100. The first guide surface and the second guide surface can cooperate with each other to guide the striking portion 100 and the curved extension portion 200 or the handle portion 300 during installation, and prevent the two components from rotating relative to each other during use, thereby affecting the use effect.

[0088] In some embodiments, the handle portion 300 is provided with a power supply 310, and the curved extension portion 200 is provided with a conductive sheet, which connects the pin 120 and the socket 220. However, the handle portion 300 can be directly connected to the striking portion 100 to provide electrical energy, or the handle portion 300 is connected to the curved extension portion 200 and the striking portion 100 in sequence, and the power supply 310 provides electrical energy to the striking portion 100 through the conductive sheet.

[0089] Furthermore, the power supply 310 may also be directly provided on the striking portion 100 , without transmitting electrical energy through the curved extension portion 200 and the handle portion 300 .

[0090] In some embodiments, the outer shell of the bendable extension 200 is made of a deformable material. The bendable extension 200 is made of a deformable material, such as rubber or a soft metal (e.g., a gooseneck), which exhibits excellent flexibility and plasticity. This type of material allows for a wider range of bending angle adjustments, allowing users to flexibly adjust the massage angle based on their needs and body part characteristics, thereby more precisely targeting specific muscle groups. Rubber, with its excellent elasticity and softness, can adapt to a variety of complex shapes and angles, providing users with a comfortable massage experience. Soft metal materials, such as goosenecks, offer high strength and stability, maintaining their shape and performance even after repeated bending, ensuring precise massage and consistent results. By utilizing this deformable material for the bendable extension 200, the fascia massage gun can better meet the massage needs of different people and body parts, reduce discomfort caused by arm joint movement, improve user comfort and convenience, and make the massage process smoother and more natural, further enhancing the product's applicability and user experience.

[0091] In some embodiments, the end of the curved extension 200 or the handle 300 is chamfered. When the curved extension 200 or the handle 300 is installed, the chamfer abuts the first buckle, disengaging the first buckle. The chamfer can be rounded or oblique. When the curved extension or handle is inserted, the chamfer abuts the buckle, causing the buckle structure to expand, deform, or rotate, disengaging the buckle. When the curved extension or handle is further inserted until the buckle reaches the slot, the buckle and the slot engage, allowing installation.

[0092] According to some embodiments of the present invention, the striking portion 200 is provided with a strip-shaped protrusion 111, and the curved extension portion 200 or the handle portion 300 is provided with a strip-shaped groove 270. The strip-shaped groove 270 and the strip-shaped protrusion 111 are capable of cooperating with each other. The strip-shaped groove 270 and the strip-shaped protrusion 111 are provided at a position where they are connected to each other. The strip-shaped groove 270 and the strip-shaped protrusion 111 serve as guides, allowing the curved extension portion or the handle portion to be inserted into the striking portion in a fixed square shape, facilitating installation and use.
