Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Referring to fig. 1, the fascia gun 10 includes a fascia gun movement 200 and a massage head 100, wherein the fascia gun movement 200 is used for driving the massage head 100 to reciprocate, so as to achieve a massage effect. As shown in fig. 2, the fascia gun core 200 can move the massage head 100 to an extended state. As shown in fig. 3, the fascia gun cartridge 200 can move the massage head 100 to a retracted state.

Referring to fig. 2-4 in conjunction with fig. 1, the fascia gun cartridge 200 includes a base 210, a motor 220, a crank 230, a rocker 240, a lever 250, a push rod 260, and a sliding sleeve 270.

The motor 220 is disposed on the base 210, and the sliding sleeve 270 is slidably disposed on the base 210 and is disposed at a distance from the motor 220. The lever 250 is rotatably disposed on the base 210 and located between the motor 220 and the sliding sleeve 270. The rear end of the crank 230 is provided at the output shaft of the motor 220, and the inclined front end of the crank 230 is rotatably connected with one end of the rocker 240. The other end of the rocker 240 is rotatably connected to one end of the lever 250, and the other end of the lever 250 is rotatably connected to one end of the push rod 260. The other end of the push rod 260 is connected to a sliding sleeve 270. Wherein, the motor 220 is used for driving the sliding sleeve 270 to do linear reciprocating motion through the crank 230, the rocker 240, the lever 250 and the push rod 260. The massage head 100 is disposed on the sliding sleeve 270. It should be understood that by the angled front end of the rocker 230 is meant that the front end of the rocker 230 is disposed at an angle relative to the axial direction of the output shaft of the motor 220.

In this way, in the present application, the force applied to the rocker 240 by the crank 230 from the output shaft of the motor 220 can be transmitted to one end of the lever 250, so that the power arm of the fascia gun core 200 is lengthened by using the principle of the lever 250, so that the power arm of the fascia gun core 200 of the present application can be longer than that of the fascia gun core of the prior art 1, and further the striking force of the massage head 100 of the fascia gun 10 using the fascia gun core 200 of the present application is improved.

Alternatively, in an example, the distance from the rotation center of the lever 250 to the end surface of the end of the lever 250 connected to the tele-lever 240 is greater than or equal to the distance from the rotation center of the lever 250 to the rotation center of the lever 250 connected to the push rod 260 in rotation, but is not limited thereto. In other examples, the distance from the rotation center of the lever 250 to the end face of the end of the lever 250 to which the tele-lever 240 is connected is ensured as long as it is possible to make the power arm in the fascia gun cartridge 200 of the present application longer than that in the fascia gun cartridge of the prior art 1.

Alternatively, in one example, referring to fig. 2-3, fascia gun cartridge 200 includes motor mount 340, and motor 220 is mounted to base 210 via motor mount 340. Further, the motor mount 340 is connected to an end of the motor 220 where the output shaft is provided, but is not limited thereto. In other examples, motor mount 340 is connected to an end of motor 220 that is not provided with an output shaft or a housing that houses motor 220, which are not shown here.

Further, referring to fig. 2-4 in conjunction with fig. 1, the fascia gun cartridge 200 includes a weight 280, the weight 280 being disposed at one end of the lever 250 for connecting to the rocker 240. The balance weight 280 is used to balance the inertial force applied to the end of the lever 250 connected to the push rod 260.

In the above manner, since the linear movement directions of the both ends of the lever 250 are opposite, the inertial force generated by the balance weight 280 can balance the inertial force received by the end of the lever 250 for connecting the push rod 260, so that the shock can be reduced. In addition, the rotation center of the lever 250 is disposed on the base 210, so that the force acting on the lever 250 can be diffused to the base 210 through the rotation center of the lever 250, not only can vibration be further reduced, but also the load of the motor 220 can be reduced by sharing the force acting on the lever 250 through the base 210, so that the service life of the motor 220 can be prolonged.

Further, referring to fig. 4 to 5 in combination with fig. 1 to 2, one end of the rocker 240 for connecting with the crank 230 is provided with a first adapter block 241, and one end of the rocker 240 for connecting with the lever 250 is provided with a second adapter block 242. The first adapter piece 241 is rotatably connected to the inclined front end of the crank 230 about the first axial direction Z1, and the second adapter piece 242 is rotatably connected to one end of the lever 250 about the second axial direction Z2. The first axial direction Z1 intersects with the second axial direction Z2 at the rotation center of the lever 250, so that the motor 220 can drive the lever 250 to rotate around the rotation center of the lever 250 when the crank 230 is driven to rotate.

In this way, during the axial rotation of the crank 230 around the output shaft of the motor 220 driven by the motor 220, the first conversion block 241 moves on a partial spherical surface with the rotation center of the lever 250 as the center of sphere, so that the lever 250 can be driven to swing by the rocker 240, and the push rod 260 drives the sliding sleeve 270 to do linear reciprocating motion.

Optionally, in an example, referring to fig. 4-5 in conjunction with fig. 1-2, the first adapter block 241 and the second adapter block 242 are disposed to intersect and enclose a dodging slot 243, and the dodging slot 243 faces a side where the lever 250 is located. The avoidance groove 243 is used for avoiding the lever 250, so that the lever 250, the rocker 240, the crank 230 and the motor 220 are assembled more compactly, and the miniaturization of the fascia gun movement 200 is facilitated.

Alternatively, in one example, referring to fig. 4-5 in conjunction with fig. 1-2, the first adapter block 241 is provided with a first adapter hole 246 along the first axial direction Z1 and the second adapter block 242 is provided with a second adapter hole 247 along the second axial direction Z2.

At least two first bearings 21 are disposed in the first transfer hole 246, and the inclined front end of the crank 230 is disposed in the at least two first bearings 21. One end of the first screw 22 extends into the first bearings 21 to be fixed with the inclined front end of the crank 230, and the other end of the first screw 22 is blocked at one side of at least two first bearings 21 away from the inclined front end of the crank 230 so as to prevent the first bearings 21 from being separated from the first transfer hole 246. At least two second bearings 31 are disposed in the second transferring hole 247, and one end of the lever 250 connected to the rocker 240 is disposed in the at least two second bearings 31. One end of the second screw 32 passes through the balance block 280 and extends into the second bearing 31 to be fixed at one end of the lever 250 connected with the rocker 240, and the other end of the second screw 32 abuts against one side of the balance block 280 away from the second adapting hole 247 to prevent the second bearing 31 from being separated from the second bearing 31 hole. Alternatively, first screw 22 and second screw 32 include, but are not limited to, self-tapping screws.

In the above manner, the rotation sleeving of the first adapting hole 246 and the inclined front end of the crank 230 is realized by using at least two bearings, and the rotation sleeving of the second adapting hole 247 and one end of the lever 250 is realized by using at least two bearings, so that the movement of the rocker 240 is more stable and is not easy to shake.
