AI Technical Summary

Technical Problem

Vacuum toilets may fail to start during peak usage periods due to insufficient vacuum, making it difficult for users to determine whether it is a malfunction or insufficient vacuum, which is especially perplexing for infrequent users.

Method used

A vacuum monitoring device was designed, including a first storage body and a second storage body. The movement of the indicator block displays the change in vacuum level. The movement of the indicator block is restricted by a flexible sealing body and an elastic element, and the device is precisely positioned by a ring-shaped limiting strip. It is installed on a vacuum toilet to monitor the vacuum level of the vacuum pipeline in real time.

Benefits of technology

It enables real-time monitoring of the vacuum level of vacuum toilets, simplifies the judgment process, improves monitoring efficiency and accuracy, and ensures that users can understand the vacuum level status in a timely manner.

Abstract

The utility model relates to a vacuum degree monitoring device which is used for being connected with a vacuum pipeline and comprises a first storage body, a second storage body and a third storage body, the second memory bank is connected with the first memory bank; an indication block is arranged in the second storage body, one end of the indication block is movably connected with the outer wall of the first storage body, and the other end of the indication block is elastically connected with the inner wall of the second storage body; a through hole is formed in the box body wall of the first storage body, the through hole is communicated with the vacuum pipeline, the vacuum degree value in the vacuum cavity is changed, so that the indicating block reciprocates, and the vacuum closestool is connected with a vacuum degree monitoring device. The vacuum degree monitoring device is simple in structure and convenient to install, and preferably, the vacuum degree in the vacuum pipeline can be judged in real time so that the vacuum closestool can be better used.
