Description

Negative pressure water distributor for toilet

Technical field

The invention belongs to the field of sanitary ware, and particularly relates to a negative pressure water distributor for a toilet.

Background technique

The toilet currently used uses a free water pressure difference to press or spray water into the toilet siphon. When the toilet siphon is filled with water, the siphon principle is used to discharge the water in the toilet into the sewer. The siphon tube refers to the S-bend under the toilet. When the water surface in the toilet exceeds the high point of the S-bend during the sewage discharge, a siphon phenomenon is formed, which can remove the water and dirt of the toilet together until only a small amount remains. When water is used, the siphon breaks down, leaving a small amount of water that forms a water seal. This type of toilet requires sufficient water to discharge the dirt during the sewage discharge process, and the inner wall of the toilet is not easily washed out.

In order to solve the above problems, the utility model patent of China Patent No. 2010206894522 provides a "piston type suction and drainage toilet", which uses the negative pressure generated when the piston moves up and down to pump away water and dirt in the toilet bowl. The purpose of cleaning the toilet can be cleaned with less water. However, in the actual use test, it was found that the reciprocating ability of the fixed stroke in the design of the piston in the design was slightly insufficient, and occasionally there was a phenomenon that the returning rebound was invalid, and the flat structure of the flat piston plug body caused the water to be weak and could not be formed. Effective secondary siphoning affects the use, so it is necessary to further improve the piston suction and drainage system in the toilet.
