1. A massage device, comprising:
(a) a housing;
(b) a massage sleeve having an opening;
(c) a transmission connection assembly including:
a guiding tube member, a piston movable axially inside the guiding tube member along a long axis, an eccentric wheel, and a link component having a first end coupled with the piston and a second end coupled with the eccentric wheel;
(d) a motor that is coupled with the eccentric wheel of the transmission connection assembly and includes an output shaft defining a shaft rotation axis which is parallel to the long axis, and when in operation, drives the piston via the transmission connection assembly to move axially inside the guiding tube member along the long axis to change air pressure in the massage sleeve,
wherein the housing includes an opening at one end, the opening aligned with and in air communication with the opening of the massage sleeve,
wherein the massage sleeve is arranged at an end of the guiding tube member of the transmission connection assembly and aligned coaxially with the guiding tube member, and
wherein the transmission connection assembly and the motor are received inside the housing.
 
10. A massage device, comprising:

(b) a massage sleeve having an opening;
(c) a transmission connection assembly including:
a guiding tube member, a piston movable axially inside the guiding tube member along a long axis, an eccentric wheel, and a link component having a first end coupled with the piston and a second end coupled with the eccentric wheel;
(d) a motor that is coupled with the eccentric wheel of the transmission connection assembly and when in operation, drives the piston via the transmission connection assembly to move axially inside the guiding tube member along the long axis to change air pressure in the massage sleeve,
wherein the housing includes an opening at one end, the opening aligned with and in air communication with the opening of the massage sleeve,
wherein the link component comprises an elongated shaft portion connected with a circular portion,
wherein the eccentric wheel has a flat major face parallel with the long axis, and comprises a bottom edge comprising a first planar tooth pattern that meshes with a second tooth pattern on a circumferential periphery of a gear of a gear assembly driven by the motor,
wherein the massage sleeve is arranged at an end of the guiding tube member of the transmission connection assembly and aligned coaxially with the guiding tube member, and
wherein the transmission connection assembly and the motor are received inside the housing.
