People nowadays lead a stressful busy lifestyle and can only find peace of mind at home. However, just because you take a good rest at home, it doesn't mean that the back pain inflicting you due to busy lifestyle and work stress is likely to be relieved. In view of this, the related industrial sector developed a conventional massage apparatus whereby a user massages the body at home to freshen up and relieve back pain.
The conventional massage apparatus operates by simply rubbing or kneading parts of the body and thus cannot refresh the body efficiently. Furthermore, the conventional massage apparatus performs rubbing or kneading monotonously and invariably and thus offers few choices to consumers; as a result, the conventional massage apparatus fails to build customer loyalty. Accordingly, the prior art has room for improvement.
It is an objective of the present invention to provide a massage device capable of kneading and percussion. The massage device is characterized in that a power source drives a rotational inclined surface and an eccentric cam, to thereby perform kneading with lateral oscillation by means of the rotational inclined surface and perform percussion by means of the eccentric cam. With a one-way bearing being disposed in the driving direction of the eccentric cam, the massage device in operation offers users two options, namely either kneading-based massage only, or both kneading-based massage and percussion-based massage.
In order to achieve the above and other objectives, the present invention provides a massage device capable of kneading and percussion. The massage device comprises a power source, a first transmission member, a second transmission member, at least a third transmission member, a casing portion, at least a kneading unit, and at least a percussion unit. The power source can be a motor. The motor drives a worm gear of the first transmission member. The worm gear drives a first gear of a first transmission shaft. A second gear of the first transmission shaft meshes with a large gear of the second transmission member. The large gear is fixed to a second transmission shaft. The second transmission shaft drives a rotational inclined surface structure. An oscillating arm abuts against the rotational inclined surface structure. The rotational inclined surface structure rotates to drive the oscillating arm to undergo lateral oscillation, thereby driving a massage head support to undergo lateral oscillation. Massage heads and infrared lamp plates rest on the massage head support. The massage heads undergo lateral oscillation and thereby perform kneading-based massage on the human body, whereas the infrared lamp plates are effective in applying a heat treatment. The first transmission member drives a third gear that comes with a one-way bearing. The third gear drives a fourth gear of the at least a third transmission member. The fourth gear and a fifth gear are fixed to a third transmission shaft. The fifth gear meshes with a sixth gear fixed to a fourth transmission shaft. An eccentric cam is disposed around the fourth transmission shaft. The eccentric cam is pivotally coupled to an eccentric spindle and thereby connected to a lever weight. The lever weight is fixed to the massage head support laterally. Hence, given reverse-rotation operation of the motor, the eccentric cam drives the massage heads to perform percussion-based massage and kneading-based massage simultaneously.

The at least a kneading unit 50 comprises a rotational inclined surface structure 51, an oscillating arm 52, a massage head support 53, two infrared lamp plates 54, and two massage heads 55. The rotational inclined surface structure 51 is fixed to the second transmission shaft 41, such that the second transmission shaft 41 rotates to drive the rotational inclined surface structure 51 to rotate. The oscillating arm 52 abuts against the rotational inclined surface structure 51. The rotational inclined surface structure 51 rotates to drive the oscillating arm 52 to undergo lateral oscillation.
