Secondary cleaning device of vacuum closestool for high-speed rail

Abstract

The invention relates to the technical field of vacuum toilets, and further discloses a secondary cleaning device of a vacuum closestool for a high-speed rail. The secondary cleaning device comprisesa toilet seat, a water tank is mounted at the left side of the top of the toilet seat, and a sitting table is integrally formed at the right side of the top of the toilet seat. An annular cavity is formed at the inner side of the sitting table, a toilet bowl belly and a sewer pipe are arranged in the toilet seat, and a water storage cavity and an adjusting cavity are formed at the inner side of the toilet seat. A connecting hole is formed between the water storage cavity and the water tank, and a connecting pipe is arranged between the water storage cavity and the annular cavity. According tothe secondary cleaning device of the vacuum closestool for the high-speed rail, the water storage cavity is installed between the water tank and the annular cavity, during flushing, the water in the water tank flows into the water storage cavity through the connecting hole and enters the annular cavity through the connecting pipe after the water storage cavity is filled with the water, and becauseof the gravity of the water, a movable plug pulls a spring to move downwards until a drainage hole moves out of the through hole, and the water in the annular cavity flows into the toilet bowl bellyfrom the drain hole, so that a sealed environment is formed.

Description

technical field [0001] The invention relates to the technical field of vacuum toilets, in particular to a secondary cleaning device for high-speed rail vacuum toilets. Background technique [0002] Due to the limited water source that the high-speed rail can carry, most of the high-speed rail toilets use vacuum toilets. Vacuum toilets can increase the pressure difference required for siphoning, use less water to achieve better flushing effects, and will not generate additional waste. Noise, which saves water for more passengers. [0003] Dozens of toilets need to be installed on a high-speed rail line. In order to save costs, high-end vacuum toilets will not be installed. However, due to the immaturity of the existing technology, ordinary vacuum toilets cannot achieve the flushing effect of traditional toilets, and excreta may remain. , so as to breed a large number of bacteria and make subsequent users feel uncomfortable, so we proposed a secondary cleaning device for high...
