A vacuum suction assistance device for a male, comprising: a cup body (1) and an adjusting piece (3); the cup body is hollow and has two permeable ends; the outer diameter of the cup body shrinks inwards at one end to form a neck (10); the neck (10) is provided with an outwards permeable first opening (11) therein, and an outwards permeable second opening (12) at the other end thereof; the first opening (11) is combined with a combining piece (2); the adjusting piece (3) is screwably locked to the combining piece (2); the vacuum suction assisting device further comprises a locking assembly (5) comprising an upper partition (501), a lower partition (510), and a membrane (52); the locking assembly (5), coordinating with the adjusting piece (3), adjusts the air to bi-directionally enter or exit from the upper partition (501), the lower partition (510) and the cup body (1), achieves the locking function via the membrane (52) so as to generate negative pressure, such that when male genitalia enters a soft rubber sleeve (4) in the cup body (1), a suction feeling or push feeling is generated immediately, and the strength of the suction force or push force can be adjusted at will via the adjusting piece (3), thus controlling the pumping speed. The vacuum suction assisting device is safe and easy to use. |
