Referring to
The massage motor 4, the running motor 17 and the heating unit 2 are connected to a power by an electric control switch to supply electricity.
The heating unit 2 is mounted inside a massage surface of the upper massage shell 3 of the massage core shell assembly. A massage plate 1 is mounted on the massage surface of the massage core shell assembly and located opposite the heating unit 2 for promoting the massage effect. The massage motor 4 and the eccentric wheel 5 are mounted between the upper massage shell 3 and the lower massage shell 6 of the massage core shell assembly. The eccentric wheel 5 is mounted on an output axle of the massage motor 4. The lower massage shell 6 of the massage core shell is pivotally mounted on the upper running shell 7 of the running core shell assembly by a pivot (comprising a bolt 9 and an anti-loosening nut 8). At least one spring 10 is disposed between the massage core shell assembly and the running core shell assembly. More precisely, the upper running shell 7 comprises at least one spring hole defined thereon, and the spring 10 passes through the spring hole and two ends of the spring are respectively supported against the lower massage shell 6 and the lower running shell 18.
The running motor 17 and the gear assembly are mounted between the upper running shell 7 and the lower running shell 18 of the running core shell assembly. The running motor 17 is in drive connection with the gear assembly. More precisely, an output axle of the running motor 17 drives the worm gear 16. The worm gear 16 drives the running gear 12 by using the bevel gear 14, the straight gear 13 and a driving shaft 15. The running gear 12 of the gear assembly meshes with the track rack 11.
When the massage mechanical core of this invention is applied to a massage product, the massage mechanical core is mounted on a massage cushion or a chair back. The track rack 11 is mounted on the back from top to bottom, and the track rack 11 is adapted to the human back to attain the better massage effect.
The heating unit 2, using a PTC heating unit in combination with a LED light to emit light or adopting a bulb, is attached to the massage plate 1, whereby the heating unit 2 transmits the heat to the human body and increases the heating function. The LED light or the bulb can emit lights.
The massage motor 4 of this invention drives the rotation of the eccentric wheel 5. The massage motor 4 is fixed between the upper massage shell 3 and the lower massage shell 6 by screws. The lower massage shell 6 is fixed on the upper running shell 7 by using the bolt 9 and the anti-loosening nut 8. Two ends of the lower massage shell 6 are supported by the spring 22 to attain an upward and downward adjustment. When the massage motor 4 rotates, the eccentric piece 5 is rotated by the massage motor 4 so that a centrifugal force is formed by the rotation of the eccentric piece 5 and transmitted from the upper massage shell 3 by the massage motor 4 to the human body. Therefore, this invention attains the massage function with hydraulic pulses by arranging an electric control program system.
This invention attains the fixed-point massage function executed by using the running motor 17 to drive the rotation of the worm gear 16, whereby the worm gear 16 drives the bevel gear 14, the bevel gear 14 drives the straight gear 13 and the straight gear 13 drives the running gear 12. By the running gear 12 which meshes with the track rack 11, this invention obtains the running function. When the running gear 12 stops at a desirable point, the running motor 17 does not work under the control but the massage motor 4 works normally so that a fixed-point massage function is attained.
This invention has a straight running function. The operation is executed by using fasteners to screw the upper running shell 7 to the lower running shell 18. Therefore, the worm gear 16 is rotated by the running motor 17, the bevel gear 14 is driven by the worm gear 16, the straight gear 13 is driven by the bevel gear 14, and the running gear 12 is driven by the straight gear 13. By the running gear 12 which meshes with the track rack 11. So, the structure constructed by engaging the cylindrical wheel structure with the rack attains the straight running massage function.

1. This invention comprises the function of simulating hydraulic impacts and vibrations, the heating function, the curved running massage function and the fixed-point massage function. This invention has not only good comfortableness and reliability but also the simple structure and low costs. Further, this invention is easily installed and detached for the production and is easy to operate. The quality of the product can also be guaranteed.
2. The designing principle and the structure of this invention are reasonable. This invention uses the eccentric piece cooperating with an electric control program to simulate a massage effect with hydraulic pulses and vibrations and uses the cylindrical gear to transmit and drive the gear assembly and the rack to attain the up and down running massage function. This invention attains the curved running massage function by working on a curved track. This invention attains the fixed-point massage function by setting the operation of the electric machine and attains the heating function by using the PTC heating unit or the bulb heating means.
This invention is suitable for household or public massage products, such as massage chairs, office chairs, massage beds, massage sofas, massage cushions and foot bathing chairs.
