The specific implementation mode is as follows:

referring to fig. 1 to 4, the compact massage machine core comprises a motor 1, a gear box 2, a massage disc 3 and rollers 4; the motor 1 is directly fixedly wrapped in the shell of the gearbox 2 to form an integrated design, the overall stability is improved, the gearbox 2 generally adopts worm gear speed change, a pair of symmetrically distributed worm gears are meshed and driven to synchronously rotate by a worm section of an output shaft of the motor 1 and then are decelerated by a rear-stage gear, and a final-stage gear shaft extends out of the shell of the gearbox to form an output shaft 21; the output shaft 21 drives the eccentric disc 5, that is, the output shaft 21 is inserted into a shaft hole of the eccentric disc 5 arranged at an eccentric position to drive the eccentric disc 5 to eccentrically rotate.

The massage disc 3 is locked at the end of the output shaft 21 penetrating through the eccentric disc 5, or a pin 51 is arranged on the eccentric disc 5, that is, the eccentric position of the eccentric disc 5 is connected with the output shaft, and the pin 51 is arranged at the central position, the output shaft 21 drives the lower eccentric disc 5 and the pin 51 to generate eccentric motion, as shown in fig. 3 and 4; if the massage disk 3 is locked at the end of the output shaft 21 passing through the eccentric disk 5, the massage disk 3 can only rotate, and the massage track changes relatively little.

An eccentric swing arm 6 is positioned outside the eccentric disc 5 in a rotating way, and the two ends of the eccentric swing arm 6 in the radial direction of the eccentric disc are respectively provided with a roller 4, which is also the reason for forming a compact structure. The swing arm 6 is provided with a limiting pin 61 facing downwards, and the motion trail of the swing arm 6 is restricted, namely the rotation of the swing arm is limited, and the swing arm is allowed to swing within a certain angle range by means of the limiting pin 61 inserted into a limiting groove 22 arranged on an upper cover of the gearbox.

That is, the massage disk 3 is driven by the motor 1 to rotate, and the eccentric disc 5 is linked with the swing arm 6 to swing, and the rollers 4 arranged at the two ends of the swing arm 6 move along with the swing, and the axial massage kneading is radially rolled.

In order to reduce the friction when the swing arm 6 moves, a shaft hole 62 with a closed end is formed in the middle of the swing arm 6, a bottom cover 63 is arranged, and a bearing 7 is installed in the shaft hole 62; the inner ring of the bearing 7 is sleeved outside the eccentric disc 5, an inner ring cover 52 is arranged on the bearing, the inner ring cover 52 is locked on the upper end surface of the eccentric disc 5, and the bearing 7 is clamped outside the eccentric disc 5.

Further, roller bases 64 are locked at two ends of the deflection arm 6, and rollers 4 are positioned on the roller bases 64 through a rotating shaft 65; the roller 4 is formed with a roller cavity 41 and is provided with an end cover 42, a lamp panel 43 is locked on the inner surface of the end cover, an infrared light tube or a red light diode is arranged on the lamp panel 43 to irradiate the roller 4, so that the roller 4 can emit far infrared rays even if the roller 4 generates heat in the whole body, and the physiotherapy purpose is achieved. Furthermore, the surface of the roller 4 is formed with rough undulation strips 44 to improve the finger pressure feeling during rolling and to increase the friction force.
