Zusammenfassung: | In a piston sucking-type massager disclosed in the present invention, a massage port of a straight-cylinder piston chamber is in contact with the human skin and then closed, a push-pull driving device drives a push-pull member to reciprocate and translate linearly, and a piston follows the action of the push-pull member to reciprocate and translate linearly in the straight-cylinder piston chamber, so that positive and negative pressures are formed in a space between the massage port of the straight-cylinder piston chamber and one end surface of the piston, for sucking massage. |
