Abstract:
1. A massage appliance capable of synchronous kneading and tapping, comprising: a power-driven vertically-moving device comprising an outer portion, wherein a sliding channel is formed inside the outer portion, and a vertically-moving rack is disposed alongside the sliding channel; a device capable of synchronous kneading and tapping comprising a housing portion and further comprising a power source being a first motor disposed inside the housing portion, wherein a spindle of the first motor is fixed to a worm gear; a first transmission device disposed inside the housing portion and comprising a first transmission shaft, a first gear, and a second gear, the worm gear meshing with the first gear and rotating to bring about rotation of the first gear and the second gear which are fixed to the first transmission shaft; a second transmission device disposed inside the housing portion and comprising a second transmission shaft, a third gear, and a fourth gear, the worm gear meshing with the third gear and rotating to bring about rotation of the third gear and the fourth gear which are fixed to the second transmission shaft; two kneading devices extending from inside the housing portion to outside the housing portion and each comprising a rotational inclined surface structure, an oscillating arm, a massage head support, and a massage head, the rotational inclined surface structure being fixed to a third transmission shaft, the third transmission shaft being fixed to a fifth gear, the fifth gear meshing with the second gear, to rotate the first transmission shaft and thereby drive the rotational inclined surface structure to rotate, the oscillating arm abutting against the rotational inclined surface structure, the rotational inclined surface structure rotating to drive the oscillating arm to undergo lateral oscillation, the oscillating arm having the massage head support coupled thereto, thereby driving the massage head support to undergo lateral oscillation, the massage head support having the massage head coupled thereto, thereby driving the massage head to oscillate laterally in a manner to perform kneading-based massage on a human body; two tapping devices extending from inside the housing portion to outside the housing portion, a fourth transmission shaft having a sixth gear coupled thereto, the sixth gear meshing with the fourth gear, wherein a one-way bearing is disposed at the sixth gear and then connected to the fourth transmission shaft, wherein two eccentric cams are disposed at two ends of the fourth transmission shaft, respectively, the eccentric cams each being disposed at an eccentric external case, the eccentric external case being pivotally coupled to an eccentric spindle with a universal joint connected to a lever weight, the lever weight being fixed to the massage head support from beside such that, as soon as the first motor starts to undergo anticlockwise revolution, the eccentric cams drive the massage head to perform tapping-based massage, thereby allowing the massage head to perform kneading-based massage in synchrony with tapping-based massage; and a second motor having a spindle fixed to a worm gear, a first large gear and a first small gear integrally formed as a unitary structure, the first large gear meshing with the worm gear, a second large gear and a second small gear integrally formed as a unitary structure, the second large gear meshing with the first small gear, a third large gear and a third small gear integrally formed as a unitary structure, the third large gear meshing with the second small gear, the third small gear meshing with the vertically-moving rack, to thereby decrease rotation speed and increase torque according to a gear ratio, such that the device capable of synchronous kneading and tapping switches between upward kneading-based tapping-based massage and downward kneading-based tapping-based massage as soon as the second motor switches between clock revolution and anticlockwise revolution.
