An automatic massage portable massage table, and belongs to the technical field of massage apparatuses. The automatic massage portable massage table includes a rigid planner surface, a cushioned pad, an upholstery cover, table legs, long leg supports, short leg supports, a cable system, a headrest cradle, a headrest cushion, and a plurality of airbags. According to the automatic massage portable massage table of the present disclosure, a user can command a circuit board to supply power to an air pump and a plurality of air valves through buttons of a controller. After being powered on, the air pump supplies air to the air valves. Meanwhile, the circuit board controls, according to a pre-stored program, the air valves to achieve air supply and air release, thus controlling the airbags to be inflated and deflated.

The present disclosure relates to an airbag type massage table, and belongs to the technical field of massage apparatuses, including a rigid planner surface, a table top, an upholstery cover, a headrest cushion, and a plurality of airbags. A user can lay in supine or prone position on the table top of the airbag type massage table of the present disclosure. A circuit board is instructed by means of buttons of a controller. The circuit board supplies power to an air pump Air pumps supply air to air valves. Meanwhile, the circuit board controls the opening, closing and air release of the air valves, thus controlling the airbags to be inflated, held and deflated.

A massage chair includes a seat portion, a back portion a leg portion, and a massage carriage configured to move within the seat portion, the back portion, and the leg portion. The massage carriage includes comprises a percussive massage assembly comprising a motor, a reciprocating shaft coupled to the motor and configured to reciprocate in response to activation of the motor, and a reciprocating massage head coupled to the reciprocating shaft. The massage chair also includes a support mechanism associated with the percussive massage assembly. The support mechanism is configured to support a weight of a user of the massage chair, thereby allowing the reciprocating shaft and the reciprocating massage head of the percussive massage assembly to reciprocate.

A percussive massage device includes a cylinder extending along a longitudinal axis. A motor shaft that rotates about a central axis perpendicular to the longitudinal axis. A crank coupled to the shaft includes a first pivot offset from the central axis. A pinion gear is coupled to the first pivot. The pinion gear rotates within a ring gear. The pinion gear has a second pivot that rotates about the first pivot. A reciprocation linkage is coupled between the second pivot and a piston that moves longitudinally within the cylinder. An applicator head coupled to a second end of the piston has an end exposed outside the cylinder for application to a person receiving treatment. An actuator selectively rotates the ring gear to cause the applicator head to have a first stroke length and at least a second stroke length.

A rotary masturbation cup which is configured to reciprocate. The masturbation cup includes an upper shell and a lower shell releasably secured to the upper shell. Top of the upper shell is provided with a push-button. Inside of the upper shell is provided with a battery powered DC motor. A circuit board is electrically connected to the DC motor. The push-button is electrically connected to the circuit board. The DC motor is covered by upper and lower covers. An output end of the DC motor is provided with a transmission gear. Bottom of the lower cover of the DC motor is provided with a roller fastening member. The lower cover of the DC motor is threadedly secured to the roller fastening member. Top of the lower shell is provided with a reciprocating roller. A reciprocating massage sleeve is disposed on an inner surface of the reciprocating roller.

A handheld focused extracorporeal shock wave therapy (f-ESWT) device includes a plurality of piezoelectric elements, a power supply circuit, and a plurality of driver circuits. The piezoelectric elements are each configured to generate an individual shock wave. The power supply circuit is configured to output a first DC voltage and a second DC voltage. The first DC voltage greater than the second DC voltage. The driver circuits are each operably connected to the first DC voltage, the second DC voltage, and to a corresponding piezoelectric element of the plurality of piezoelectric elements. Each driver circuit includes a switching element electronically configurable in an open state and in a closed state. When the switching element is in the open state, the first DC voltage and the second DC voltage are applied to the corresponding piezoelectric element to pre-charge the corresponding piezoelectric element with a DC pre-charge voltage having a first polarity.
