This application discloses a cover device, a toilet cover assembly and a toilet, the cover device including a cover (2), at least one shaft sleeve (2-1, 2-2) provided on one end of the cover (2), the cover device further including at least one helical spring (5-1, 5-2) and at least one damper (4-1, 4-2); an outer end of the at least one helical spring (5-1, 5-2) is fixedly connected to the at least one shaft sleeve, such that the cover (2) applies a compression force to the at least one helical spring (5-1, 5-2) when rotating downward; and a bearing of the at least one damper (4-1, 4-2) penetrates through the center of the at least one helical spring (5-1, 5-2) and is fixedly connected to an inner end of the helical spring (5-1, 5-2), and an outer cylinder part of the at least one damper (4-1, 4-2) is fixedly connected to the at least one shaft sleeve (2-1, 2-2), such that the at least one damper (4-1, 4-2) resists against elastic force release of the at least one helical spring (5-1, 5-2), wherein the rated elastic force of the at least one helical spring (5-1, 5-2) is larger than the gravity of the cover (2). This invention makes the cover rise up automatically and slowly without use of electricity, which not only is simple in structure, but also is safe and saves energy.

The present disclosure discloses an assembly and disassembly base. The assembly and disassembly base comprises a fixed plate set, a locking plate, and a fixing screw, the fixed plate set and the locking block are disposed with a plurality of protruding blocks, the locking plate is slidably disposed in the fixed plate set, the protruding blocks are overlapped and staggered, thereby resulting the locking and the disassembly of the locking plate and the fixed plate set to be achieved. The locking plate is connected to the toilet seat by the fixing screw.

The present disclosure discloses an assembly-and-disassembly structure for a toilet cover, which comprises a cover plate assembly, two support bases, and two rotation shafts. A torsion spring is disposed between the first locking rod and the second locking rod. A first end of the torsion spring is movably connected to the first locking rod, and a second end of the torsion spring is connected to the second locking rod. The second locking rod comprises a torsion spring fixing portion. An outer end of the first locking rod comprises a first locking plate, and an inner end of the first locking rod comprises a sliding groove structure configured to receive the first end of the torsion spring to move.

The automated toilet seat lifting system comprises a toilet and a lifting mechanism. The lifting mechanism attaches to the toilet. The toilet further comprises a tank, bowl, toilet seat, and a toilet lid. The lifting mechanism is an automated device used to raise and lower the toilet seat and the toilet lid in preparation for and during the use of the toilet. The lifting mechanism operates such that the toilet seat and toilet lid are raised when a client is detected in the proximity of the toilet. The lifting mechanism returns the toilet seat to a lowered position when the client is no longer detected in the proximity of the toilet.
