Control device for discharge pipe of water saving closet

Abstract

The present invention relates to a device for controlling drainage pipe of water-saving type toilet seat, which comprises a drainage pipe, a restore spring and a level-limiting mechanism. One end of the restore spring connects with the restore spring, while the other end is fixed. Said level-limiting mechanism consists of a level-limiting plate, a lifting plate, a pulling string and a floating block. The level-limiting plate is rotatably arranged under the drainage pipe, one end of the pulling string connects with the lifting plate, while the other end connects with the floating block, said level-limiting plate can determine whether limiting the level of drainage pipe or not automatically according to the water-level in water tank, so as to ensure unblocking when flushing, and keep enough deodorizing water seal when not flushing. The elasticity parameter of the restore spring can be conveniently regulated through pulley or pulley block.

Description

Technical field: [0001] The invention relates to a toilet, in particular to a control device for a sewage discharge pipe of a water-saving toilet. Background technique: [0002] The applicant applied for a water-saving toilet on April 26, 2003. The patent application number is: 03113333.9. The position of the sewage pipe of the toilet changes during use. There is a flexible hose between the toilets, and the position of the sewage pipe is automatically controlled by a spring. During use, the water-saving and one-time sewage discharge of this toilet are ideal, but when it is not in use, when people When domestic water is poured into the urinal to flush the urine, the water in the urinal will be emptied, which will affect its airtightness, and the deodorization performance cannot be guaranteed. At the same time, it is difficult to determine the elastic parameters of the spring that controls the sewage pipe. Spring selection is difficult. Invention content: [0003] The purp...
