AI Technical Summary
Technical Problem
Users often forget to close the lid when using traditional toilets, leading to environmental hygiene problems.
Method used
Design an automatic lid that uses a compressed air device and a pneumatic limit device to achieve automatic lid closing through a mechanical structure. Combined with a slow-leak valve to control the air leakage rate of the pneumatic limit device, and a delayed reset structure to achieve delayed closing function.
Benefits of technology
The toilet lid closes automatically after the user finishes using the toilet, solving the problem of forgetting to close the lid. At the same time, it retains the traditional features of a toilet, has high operational reliability, long service life, and does not affect the user experience.

Abstract
The automatic cover plate comprises a base, a seat ring and a toilet cover, the base is provided with an air compression device and a pneumatic limiting device, the air compression device is provided with an air return structure, and the pneumatic limiting device is provided with a slow leakage valve; the seat ring is rotatably mounted on the base, and the seat ring in a seated state can close the slow leakage valve; the barrel cover is rotationally installed on the base and is in transmission fit with the air compression device, a first reset structure matched with the pneumatic limiting device is arranged between the barrel cover and the base, and when the barrel cover rotates from the closed position to the open position, the barrel cover drives the air compression device to exhaust air in the air compression device to the pneumatic limiting device through the first flow channel; the pneumatic limiting device is driven to limit work of the first reset structure. According to the automatic cover plate, the barrel cover can be automatically closed after a period of time of defecation of a user, the problem that the user forgets to cover the barrel cover after defecation is solved, and the user is allowed to open or close the barrel cover at any time according to needs.
