Abstract

A female masturbation device includes a casing, a flexible cup body, a flexible piston, a slide bar, a silica-gel rod and a driver. An exterior wall of a lower end portion of the casing is connected with an upper end of the flexible cup body and an upper end of the flexible piston from the top down in turn. The flexible piston is provided within the flexible cup body forming a negative pressure region between the flexible piston and the flexible cup body. The slide bar passes through the flexible piston, an upper end of the slide bar is connected with the driver, and a lower end of the slide bar is tightly fastened with an upper end of the silica-gel rod. The flexible cup body has a through hole, an arched convergence part and an annular bottom ring. The female masturbation device has the obvious masturbation effect on female.

Claims

1. A female masturbation device, comprising:

a casing having a hollow body, a flexible cup body, a flexible piston, a slide bar, a silica-gel rod and a driver,

wherein an exterior wall of a lower end portion of said casing is connected with an upper end of said flexible cup body and an upper end of said flexible piston from the top down in turn,

wherein said flexible piston is provided within said flexible cup body forming a negative pressure region between said flexible piston and said flexible cup body,

wherein said driver, adapted for providing said slide bar with power, is provided within said casing,

wherein said slide bar runs through said flexible piston and is tightly fastened therewith, an upper end of said slide bar is connected with said driver, a lower end of said slide bar is tightly fastened with an upper end of said silica-gel rod,

wherein said flexible cup body has a through hole provided at a central part of a lower end thereof, an arched convergence part, having a W-shape and bending towards said through hole, formed at a lower end portion of said flexible cup body, and an annular bottom ring surrounding a peripheral edge of said arched convergence part,

wherein said slide bar comprises a transversely convex edge provided at a position where said slide bar passes through said flexible piston, and a valve device provided on said transversely convex edge.

2. The female masturbation device, as recited in claim 1, wherein said lower end of said casing is threadedly connected with said upper end of said flexible cup body.

3. The female masturbation device, as recited in claim 1, further comprising a sealing ring provided at the upper end of said flexible cup body.

4. The female masturbation device, as recited in claim 2, further comprising a sealing ring provided at the upper end of said flexible cup body.

5. The female masturbation device, as recited in claim 3, wherein said lower end of said casing is snap-connected with said upper end of said flexible piston, said sealing ring is provided on an exterior wall of said upper end of said flexible piston, such that said upper end of said flexible cup body and said upper end of said flexible piston are sealed.

6. The female masturbation device, as recited in claim 4, wherein said lower end of said casing is snap-connected with said upper end of said flexible piston, said sealing ring is provided on an exterior wall of said upper end of said flexible piston, such that said upper end of said flexible cup body and said upper end of said flexible piston are sealed.

7. The female masturbation device, as recited in claim 1, wherein said lower end of said slide bar is threadedly connected with said upper end portion of said silica-gel rod.

8. The female masturbation device, as recited in claim 2, wherein said lower end of said slide bar is threadedly connected with said upper end portion of said silica-gel rod.

9. The female masturbation device, as recited in claim 3, wherein said lower end of said slide bar is threadedly connected with said upper end portion of said silica-gel rod.

10. The female masturbation device, as recited in claim 4, wherein said lower end of said slide bar is threadedly connected with said upper end portion of said silica-gel rod.

11. The female masturbation device, as recited in claim 5, wherein said lower end of said slide bar is threadedly connected with said upper end portion of said silica-gel rod.

12. The female masturbation device, as recited in claim 6, wherein said lower end of said slide bar is threadedly connected with said upper end portion of said silica-gel rod.

13. The female masturbation device, as recited in claim 1, wherein said valve device comprises a ventilation hole through said transversely convex edge and a valve movably fitted on said ventilation hole.

14. The female masturbation device, as recited in claim 3, wherein said valve device comprises a ventilation hole through said transversely convex edge and a valve movably fitted on said ventilation hole.

15. The female masturbation device, as recited in claim 1, further comprising a control box adapted for controlling an operation of said driver, located outside said casing.

16. The female masturbation device, as recited in claim 3, further comprising a control box adapted for controlling an operation of said driver, located outside said casing.

17. The female masturbation device, as recited in claim 1, further comprising a handrail provided on said casing 1.

18. The female masturbation device, as recited in claim 3, further comprising a handrail provided on said casing 1.

19. The female masturbation device, as recited in claim 1, wherein said flexible cup body and said flexible piston are made of rubber or silica gel.
