A foot massager includes a plurality of roller massagers, two rotational massagers, a power source, a forward-and-backward-movable device, a first transmission device, and a second transmission device. The power source rotates clockwise and drives the first transmission device and the second transmission device, such that the first transmission device drives a one-way bearing to perform idle rotation and drives the roller massagers to perform rolling massage, whereas the second transmission device drives the two rotational massagers to perform rotational massage. The power source rotates anticlockwise and drives the first transmission device and the second transmission device, such that the first transmission device drives the one-way bearing to drive the foot massaging base to move forward and backward in its entirety and drives the roller massagers to perform rolling massage, whereas the second transmission device drives the two rotational massagers to perform rotational massage. |

1. A foot massager, comprising:
a massager base being rectangular frame-like, having an opening upward, and having therein a sliding recess for use in forward and backward movement; a foot massaging base disposed inside the sliding recess; a power source disposed inside the foot massaging base and being a two-axis motor having a first driving worm and a second driving worm; a plurality of roller massagers pivotally disposed on a top surface of the foot massaging base and having a plurality of shaft portions, every two adjacent shaft portions being connected and thus power-driven by means of a timing belt and two pulleys, the shaft portions each having a plurality of massage wheels fixed thereto, wherein a bevel gear is penetratingly disposed at the outermost shaft portion and fixed thereto; two rotational massagers protrudingly disposed on the top surface of the foot massaging base, wherein a gear is disposed at a bottom of each of the two rotational massagers and penetratingly disposed inside the foot massaging base, wherein a plurality of massage heads is protrudingly disposed on a top surface of the rotational massagers; a first transmission device disposed inside the foot massaging base and comprising a first and second gears integrally formed as a unitary structure, the first gear meshing with the first driving worm, wherein a third gear and a fourth bevel gear are integrally formed as a unitary structure, the third gear meshing with the second gear, the fourth bevel gear meshing with the bevel gear to thereby drive the roller massagers to rotate, the first transmission device further comprising a fifth gear meshing with the first driving worm and having therein a one-way bearing, wherein the one-way bearing ensures that the two-axis motor can rotate in one direction to drive only if the two-axis motor rotates in the other direction to perform idle rotation, wherein a sixth gear is coaxially and fixedly disposed at the one-way bearing and meshes with a seventh gear, the seventh gear meshing with an eighth gear, the eighth gear being integrally formed with a ninth bevel gear; a second transmission device disposed inside the foot massaging base and comprising two tenth gears each meshing with the second driving worm, the two tenth gears each being integrally formed with an eleventh gear, the two eleventh gears meshing with the two gears of the two rotational massagers, respectively; and a forward-and-backward-movable device disposed inside the foot massaging base and comprising a rod having a guide groove, the rod being pivotally disposed on the foot massaging base, wherein a bevel gear is fixedly disposed at an end of the rod to mesh with the ninth bevel gear, wherein a fixing base is fixed to the massager base, and a guide bump disposed on the fixing base is engaged with and disposed in the guide groove of the rod, such that the rod rotates and drives the foot massaging base to move forward and backward in its entirety, wherein the two-axis motor rotates clockwise and drives the first transmission device and the second transmission device simultaneously, such that the first transmission device drives the one-way bearing to perform idle rotation and drives the plurality of roller massagers to perform rolling massage, whereas the second transmission device drives the two rotational massagers to perform rotational massage, wherein the two-axis motor rotates anticlockwise and drives the first transmission device and the second transmission device simultaneously, such that the first transmission device drives the one-way bearing to drive the foot massaging base to move forward and backward in its entirety and drives the plurality of roller massagers to perform rolling massage involving forward and backward movement, whereas the second transmission device drives the two rotational massagers to perform rotational massage involving forward and backward movement. |
