Description

Technical Field

[0001] The invention relates to health care equipment, and more particularly to a fascia gun. Background Art

[0002] The fascia gun can be used to massage the neck, shoulders, arms, Achilles tendon, soles of the feet and other parts with small contact surfaces, and can even be used to massage small muscles and other soft tissues in the joint sockets; compared with massage chairs, the fascia gun can be used to massage a wider range of parts on the front and sides of the human body. It uses a massage head for striking, and the striking frequency is mostly about 300 times per minute, and the amplitude is mostly around 10mm. However, due to its high striking frequency, it cannot be used to massage a single position for a long time, otherwise it is easy to damage muscle tissue, especially when massaging bones such as the spine, the pressure cannot be too high, but a lighter force is used to massage the area near the spine. The high-frequency striking method can also cause dizziness over a long period of time. Therefore, the fascia gun was not designed to take into account long-term continuous operation, but many non-athletes, such as those who sit for a long time, stand for a long time, that is, those who maintain a posture, also use fascia guns to massage the whole body to relieve soreness and discomfort. However, the fascia gun is small in size, generates a lot of heat, and takes a long time to massage the whole body. Especially for low-quality fascia guns, the smell of plastic can be smelled after long-term use, which poses a safety hazard. Summary of the invention

[0017] A fascia gun comprises a shell with a right opening, a handle is fixedly connected to the right side of the lower end of the shell, a motor is positioned inside the shell, the motor drives an eccentric wheel connecting rod mechanism to drive a massage part with clearance fit on the left side of the shell to reciprocate left and right, the position where the motor is installed in the shell has a cavity connected to the opening on the shell, the cavity is used to create a gap between the outer wall of the motor and the inner wall of the shell, when the mechanism is actuated, airflow can be generated at the opening to increase air fluidity and improve heat dissipation capacity, the airflow discharges the heat emitted by the motor from the opening, thereby increasing the maximum continuous use time, and the motor is preferably a brushless motor to further increase the use time.

[0018] A detachable cover for closing and opening the opening is installed on the right part of the housing through a threaded connection.

[0019] Among them, Figure 3 and 4As shown, the shell includes a cylindrical seat shell 11, an open structure on the seat shell 11, and a lower arm shell 12 is integrally connected to the left end of the seat shell 11. The lower arm shell 12 is an arc-shaped structure with an upper opening, and is detachably fixed to the upper end of the lower arm shell 12 with an upper arm shell 41 by screws. An air passage connected to the opening is generated between the lower arm shell 12 and the upper arm shell 41, and a connecting wall Ⅰ14 is integrally connected to the right end of the lower arm shell 12 and is a semi-ring structure. A connecting wall Ⅱ42 is integrally connected to the right end of the upper arm shell 41 and is a semi-ring structure. The connecting wall Ⅰ14 and the connecting wall Ⅱ42 fit together to form an annular wall body and the outer ring is provided with a thread; the cover includes a cover body 16, and the inner ring of the cover body 16 is threadedly connected to the outer ring of the annular wall body.

[0020] Among them, Figure 5 and 6 As shown, the cover also includes an inner cover 21, which is inserted into the right end of the annular wall body by friction, and the diameter of the right end edge of the inner cover 21 is equal to the diameter of the annular wall body to achieve positioning, and the inner cover 21 is provided with an air port 22 connected to the airway, an inner ring 23 inserted into the left end of the inner cover 21 by friction, and a filter screen 24 fixed to the inner ring 23; further, in order to facilitate the inner ring 23 to be pushed out of the inner cover 21 from the air port 22 for easy disassembly, the inner ring 23 should be exposed at the air port 22.

[0021] Further, such as Figure 2 and 7 As shown, the left end of the seat shell 11 is connected to a sleeve shell 13 connected to the airway; the eccentric wheel connecting rod mechanism includes a motor 15, the bottom of the motor 15 is fixedly connected in the seat shell 11, the output shaft of the motor 15 is arranged upward, the drive disk 31 is fixedly connected to the upper end of the output shaft of the motor 15, and the eccentric position of the upper end of the drive disk 31 is fixedly connected to a transmission shaft 32, the right part of the transmission arm 33 is rotatably connected to the transmission shaft 32, the left part of the transmission arm 33 is fixedly connected to the shaft I 34, the seat 35 is a concave structure, the opening of the seat 35 faces right, the right side of the seat 35 rotates to the upper and lower sections connected to the shaft I 34, and the seat The left part of the guide rod 35 is slidably connected to two guide rods 36, the right end of the guide rod 36 is fixedly connected to the limiter 37, the slider 38 is fixedly connected to the left end of the guide rod 36, the guide rod 36 is sleeved with a compression spring that abuts on the seat 35 and the slider 38, and the left end of the slider 38 is fixedly connected to a connecting column 39; the slider 38 is loosely fitted in the sleeve 13, and when the motor 15 is started, the drive disk 31 is driven to rotate, and the drive disk 31 drives the transmission arm 33 to reciprocate left and right by using the transmission shaft 32, and the slider 38 can slide back and forth left and right; the massage part is inserted at the left end of the connecting column 39 to achieve left and right reciprocating motion. The compression spring on the guide rod 36 can prevent the fascia gun from having an overly hard touch when massaging bones, and also reduce the dizziness caused by massaging the back spine. Preferably, when the limiter 37 contacts the transmission arm 33, the spring does not reach the maximum compression amount.

[0022] Further, such as Fig.11 As shown, the massage member includes a three-way column 71 with a right opening and plugged into the left end of the connecting column 39, and two massage parts 73 respectively fixed to the left end and the lower end of the three-way column 71;

[0023] When it is necessary to massage the area near the back spine, the downwardly extending massage part 73 is used to repeatedly reciprocate to rub the muscle tissue, joints or nodules to relax and stretch them, relieve itching and pain, and avoid high-frequency impact massage of the spine area causing dizziness and nausea. When the operator puts the right hand from the upper right back to the back, the massage part 73 at the lower end of the figure is perpendicular to the back, which makes massage more convenient without the discomfort caused by further bending of the arm and avoiding reducing the extension range of the arm.

[0024] Preferably, an aluminum alloy sheet is provided at the lower end of the lower massage portion 73, which is convenient for applying essential oil or gel and directly contacting the skin, thus avoiding the discomfort caused by the rubber material pulling the skin and improving the experience.

[0025] Furthermore, a slot 310 is provided at the left end of the connecting column 39, and the shape of the slot 310 is preferably a prismatic structure, and more preferably a rectangular structure. The right end of the inside of the three-way column 71 is fixedly connected with a plug post 72, and the plug post 72 is inserted into the slot 310 by friction, so that the plug post 72 cannot rotate in the slot 310, thereby preventing the massage part 73 from rotating and deviating during high-frequency pushing and kneading of the back.

[0026] Further, such as Figures 8 to 11 As shown, the grip includes a handle Ⅰ51 fixedly connected to the lower end of the seat shell 11, and the left end of the handle Ⅰ51 is provided with two upper and lower slots 52, and the two slots 52 are rotatably connected with shafts Ⅱ53, and the two shafts Ⅱ53 are respectively fixedly or rotatably connected to the right end of an extension arm 62, and the handle Ⅱ61 is integrally connected to the left ends of the two extension arms 62. A ring seat 54 is fixedly connected to the lower side of the handle Ⅰ51, and at least three plug holes 55 are provided on the ring seat 54, and each plug hole 55 is spaced 90 degrees in the circumferential direction. If there are four plug holes, the plug holes 55 are respectively located in the four directions of front, back, left and right. When there are three plug holes 55, it is preferred to cancel the plug hole located on the front side. Hole 55 is provided so that the socket 55 located at the rear side can be retained. This retention scheme is convenient for right-hand use. Furthermore, a mounting groove 63 is provided on the upper end surface of the extension arm 62 located at the lower side. The lower end of a spring 64 is fixedly connected in the mounting groove 63. A positioning column 65 is fixedly connected to the upper end of the spring 64. The positioning column 65 can be inserted into any socket 55 from bottom to top so that the relative positions of handle II 61 and handle I 51 remain unchanged. The upper end of the positioning column 65 is preferably an arc surface, so that the positioning column 65 can be pressed down to make the positioning column 65 descend until it is squeezed on the lower end of the extension arm 62 by the arc surface. At this time, the spring 64 is compressed, so that the extension arm 62 can continue to rotate.

[0027] When handle II 61 is located at the rear side of handle I 51, the angle between the two is 90°. At this time, when the right hand is used to hold handle II 61, it is convenient to increase the distance that the massage part 73 extends to the left side of the back when the right hand is placed on the back, reducing the hand-changing operation, and this angle is more comfortable when the massage part 73 at the lower end is pushed and kneaded, and the elbow joint will not be hurt. When handle II 61 is adjusted to the right side of handle I 51, the fascia gun is extended as a whole, which is convenient for massaging the legs and feet.

[0028] Preferably, a bolt is screwed into the connecting column 39 in the slot 310 by means of a thread, which is not shown in the figure. The head of the bolt is located at the right end of the slot 310 facing left, and the tail passes through the compression spring 38 from left to right to rest against the left end of the seat 35, so that the compression spring cannot continue to be compressed, so that the massage touch of the fascia gun returns to normal, so as to massage the muscle tissue.
