Example 1

As shown in fig. 1 and 2, the present embodiment provides a drive mechanism including: a suction chamber 7, an eccentric mass 9 and a motor 10.

The suction chamber 7 has an opening, and the eccentric mass 9 includes a rotation center connected to a rotation shaft of the motor 10 and an eccentric portion drivingly connected to a non-central position of an outer wall of the suction chamber 7. The straight line of the opening direction of the air suction chamber 7 is not coincident with the straight line of the eccentric block 9 and the motor 10, and has an included angle of not 90 degrees. Wherein, the non-central position of the outer wall of the air suction cavity 7 is integrally provided with an eccentric block connecting part, and the eccentric part of the eccentric block 9 is rotatably connected on the eccentric block connecting part. The battery 11 is electrically connected to the motor 10 to supply electric power to the motor.

The utility model discloses a driving principle as follows:

the motor 10 rotates to drive the eccentric block 9 to do rotary motion, the eccentric block connecting part on the outer wall of the air suction cavity 7 converts the rotary motion into reciprocating pushing and stretching motion under the action of the eccentric block 9, the air suction cavity 7 is driven to do compression and stretching actions repeatedly, the volume in the air suction cavity 7 is made to change in a reciprocating mode, and therefore the air suction and expiration effects are generated at the opening of the air suction cavity 7. The point of action of the movement of the eccentric mass 9 is on the side of the suction chamber 7 instead of the central one, plus the motor 10 and the eccentric mass 9 are of inclined design, saving space for the whole product.

Example 2

This embodiment is a further modification of embodiment 1, and the driving structure of embodiment 1 is applied to a massage machine.

In addition to the driving mechanism in embodiment 1, the massage machine of the present embodiment further includes: a suction head 6 and a shell.

The shell is detachably connected with one end of the suction head 6, and the suction cavity 7, the eccentric block 9 and the motor 10 are arranged in the shell.
