AI Technical Summary
Technical Problem
Conventional negative pressure massagers face issues such as poor usability due to large tensile forces, detachment of seal stoppers, and the need for battery operation, limiting the convenience and reliability of multiple stimulations.
Method used
A rotary negative pressure type adult toy with a closed-loop screw drive structure and guide mechanism that ensures linear motion of the seal portion, preventing detachment and requiring rotational operation, enhancing stability and reliability.
Benefits of technology
The design provides a stable and intuitive operation with linear pressure transition, avoiding detachment and snagging issues, offering a safer and more reliable user experience with improved usability and versatility.

Abstract
This invention provides a rotary negative-pressure type adult toy that avoids the problem of the seal and drive mechanism separating, thereby improving reliability and convenience of use. [Solution] The rotating negative pressure type adult toy includes a cup 1 and a sealing part 2. The cup is a negative pressure chamber with an opening 10 at its lower end. The sealing part is slidably mounted inside the negative pressure chamber. A through hole 12 is provided at the rear end of the cup. The sealing part is in close contact with the inner wall of the negative pressure chamber. The sealing part is provided with a drive unit protruding from the through hole. A torsion seat 3 is pivotally mounted on the upper part of the cup. A closed-loop screw drive structure for sliding the sealing part is provided between the inner wall of the torsion seat and the outer wall of the drive unit. A guide structure is provided between the sealing part and the cup to restrict the rotation of the sealing part. By providing a closed-loop screw drive structure between the inner wall of the torsion seat and the outer wall of the drive unit, reciprocating linear motion of the sealing part inside the cup is achieved. The guide structure restricts the rotation of the sealing part, ensuring that it can only slide axially without rotating together with the torsion seat.
