Title:
MALE ERECTION ASSISTANCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/151566
Kind Code:
A1
Abstract:
A male erection assistance device, comprising an erection assistance device body (200), a machine head (100), and an air extraction mechanism (300). An accommodating cavity and an air exchange hole (270) are sequentially formed in the erection assistance device body (200), and the air exchange hole (270) is communicated with the accommodating cavity. The machine head (100) is sleeved on the erection assistance device body (200), and can perform linear reciprocating motion in an air extraction direction. One end of the air extraction mechanism (300) is connected to the machine head (100), and the other end passes through the air exchange hole (270); the accommodating cavity is divided into a first accommodating cavity (240) and a second accommodating cavity (230), and the air extraction mechanism (300) can perform linear reciprocating motion in the first accommodating cavity (240), such that air in the second accommodating cavity (230) can enter the first accommodating cavity (240) unidirectionally. The machine head (100) is held to control the air extraction mechanism (300) to extract the air in the accommodating cavity, such that a negative pressure is generated in the second accommodating cavity (230), thereby improving the efficiency of the male erection assistance device reaching the negative pressure, and reducing the production cost of the male erection assistance device.
