  • Patent number: 12642738
    Abstract: A male masturbator includes a sleeve, a flexible piece, a telescopic piece, and a negative pressure driving component. The sleeve defines an accommodating space, a first opening, and a second opening. The first opening and the second opening are disposed along an axial direction of the sleeve and are communicated with the accommodating space. The flexible piece and the telescopic piece are at least partially disposed in the accommodating space. The flexible piece and the telescopic piece are disposed in sequence along the axial direction of the sleeve and toward the second opening. The negative pressure driving component is communicated with the first opening of the sleeve and enables a negative pressure to be formed in the sleeve, so that the flexible piece is driven to move toward the first opening and the telescopic piece is driven to move toward the first opening.
