at present, a motor drives more than two massage heads to rotate after being decelerated by a worm gear box, the two rotating massage heads combine various massage methods, the experience of people is enriched, but the massage heads only rotate, obviously, the change is lacked, and therefore, manufacturers also make a plurality of assumptions. Such as:

patent application No. 201410721202.5 discloses a massage movement of a massager, which comprises a main massage movement, a transmission member and a push-pull massage mechanism; the main massage machine core comprises a power output component and two massage heads connected and linked with the power output component, the transmission component is fixed below one massage head and connected and linked with the massage head, the push-pull massage mechanism is positioned between the two massage heads and connected and linked with the transmission component, and therefore the massage machine core structure with the push-pull massage function is formed. More specifically, a driving gear is locked below the massage heads and is meshed with the driven gear, a push rod with massage salient points is positioned on the end face of the driven gear through a guide shaft, and the other end of the push rod is positioned in a chute, so that the push rod can swing left and right under the driving of the driven gear to increase the massage action of the part between the two massage heads. However, the power is transmitted by meshing a pair of gears, so that the manufacturing cost is high, and the exposed gears are easy to roll external thin objects, which causes faults.

How to provide a massage core of more simple reasonable linkage relation becomes the object of the utility model.

The invention content is as follows:

the utility model aims to design an additional skin scraping massage machine core which drives a skin scraping device to act through a traction arm by an eccentric wheel.

The utility model discloses technical scheme realizes like this: an additional skin scraping massage machine core comprises a motor, a worm gear case and a massage head; the motor is driven by the output shaft of the worm gear case to rotate after the speed of the worm gear case is changed; the method is characterized in that: an eccentric wheel is fixed on an output shaft of the worm gear box, a traction arm is movably sleeved outside the eccentric wheel, and a scraping device is positioned at the far end of the traction arm; the lower end of the scraping device or the far end of the traction arm is provided with a sliding block which is constrained in a sliding groove on the surface of the worm gear case to move.

The worm gear box is symmetrically provided with two output shafts, eccentric wheels are arranged on the two output shafts, a traction arm is movably sleeved on the two output shafts, the far ends of the two traction arms are hinged with each other, a traction structure is formed on the scrapping device together, and the sliding groove is positioned on the central axis of the two output shafts.

The skin scraping device has the following two structures: the device is of a roller type structure and comprises a U-shaped arm and a scraping roller supported by the U-shaped arm; and the second one is a plate structure and comprises a support plate and one to three convex points connected with the top end of the support plate.

The utility model makes full use of the rotary output shaft, drives the scrapping device to act through the eccentric wheel and the traction arm, generates additional massage action, forms a combination with the rotary kneading, and improves the monotonous massage manipulation; the device has the characteristics of reasonable overall design, simple structure, reliable operation and flexible action.

The specific implementation mode is as follows:

referring to fig. 1, 2 and 3, the additional skin scraping massage machine core comprises a motor 1, a worm gear case 2, a massage head 3 and a skin scraping device 4; after the motor 1 is changed in speed by the worm gear case 2, the massage head 3 is driven to rotate by the output shaft 21 of the worm gear case; the typical scheme is that two symmetrical gear pairs are arranged in the worm gear box 2 to form a double-output shaft 21 structure, and the two massage heads 3 are driven to rotate reversely to form a kneading action, which is also the most common and simpler massage scheme at present.

An eccentric wheel 5 is locked on an output shaft 21 of the worm gear box, a traction arm 51 is movably sleeved outside the eccentric wheel 5, and a scraping device 4 is positioned at the far end of the traction arm 51; the lower end of the scraping device 4 or the distal end of the traction arm 51 is provided with a sliding block 41, in this example, the sliding block 41 is arranged at the lower end of the scraping device 4, and the sliding block 41 is constrained in a sliding groove 22 on the surface of the worm gear case and can only move according to a designed track, such as only moving along a central axis in fig. 2. Theoretically, the scraping device 4 can be pulled to move only by arranging the eccentric wheel 5 on one output shaft 21, but the balance of the traction force is considered, and the device is designed as follows:

the worm gear case 2 is symmetrically provided with two output shafts 21, both provided with eccentric wheels 5, and movably sleeved with traction arms 51, the far ends of the two traction arms 51 are hinged with each other to form a traction structure for the scraping device 4, and the sliding groove 22 is positioned on the central axis of the two output shafts 21. More specifically, the far ends of the two traction arms 51 are formed with shaft holes 52, and the ends are in a male-female surface or tongue-and-groove matching structure, the thickness of the two traction arms is consistent with that of one traction arm 51 after the two traction arms are overlapped or embedded, the assembly height of the two eccentric wheels 5 is also consistent, the load of the full-power worm gear case 2 is balanced, and the shaking caused during the operation is reduced. The scraping device 4 is provided with a shaft section 42, and the shaft section 42 passes through the shaft hole 52 at the end part of the traction arm without interfering the relative rotation of the two.

Further, the skin scraping device 4 has the following two structures:

the roller type roller comprises a U-shaped arm 43 and a scraping roller 44 supported by the U-shaped arm, and the scraping roller 44 is utilized to form a reciprocating type rolling action; besides the smooth surface, the scraping roller 44 can also be provided with salient points to enhance the stimulation effect.

The second one is a plate structure, including the support plate and one to three bumps connected with the top end of the support plate; i.e. a simplified design of the last solution, being a reciprocating scraping.

More specifically, the scraping device 4 is designed in a sectional manner, the sliding block 41 and the shaft section 42 are connected, and then the upper end of the shaft section 42 is inserted into the U-shaped arm 43 and fastened by screws.

Referring to fig. 4, the single traction arm 51 is used to draw the structure of the scraping device 4, theoretically, the scraping device 4 can also be drawn to reciprocate, in this structure, the massage force between the sliding block 41 and one side of the sliding groove 22 is large, therefore, a bearing or a pulley can be installed on the sliding block 41, and the sliding block is contacted with the sliding groove 22 through the bearing or the pulley, so as to reduce the resistance.
