AI Technical Summary

Technical Problem

Existing HVAC duct cleaning devices cannot effectively clean duct bends or diameter changes, and there is a high risk of duct rupture if pressure is not released in time after using cleaning agents.

Method used

Design a cleaning mechanism that includes an injection pipe, an installation pipe, and a pressure relief pipe. The pressure relief pipe is equipped with a pressure relief component that automatically responds to pipeline pressure. It can be quickly disassembled and assembled through a threaded connection. The pressure relief is automatically adjusted by the cooperation structure of the conical groove and the ball to ensure the stability of the internal pressure of the pipeline.

Benefits of technology

It achieves effective cleaning of HVAC ducts, reduces the risk of duct rupture, improves operational safety and efficiency, and ensures precise control and stability of pressure relief.

Abstract

This utility model relates to the technical field of pipeline cleaning equipment, and in particular to a cleaning mechanism for HVAC pipelines. It includes an injection pipe installed on the HVAC pipeline body, a control valve on the injection pipe, and an installation pipe threadedly connected to the front end of the injection pipe. The installation pipe connects to a pressure relief pipe, and the pressure relief pipe contains a pressure relief component that automatically opens and closes based on the internal pressure of the pipeline. The threaded connection allows for quick assembly and disassembly. The pressure relief component automatically responds to changes in pipeline pressure without manual intervention, improving safety and operational efficiency. It also solves the technical problem in existing technologies where failure to release pressure promptly after using cleaning agents leads to HVAC pipeline rupture, and achieves the goal of effectively cleaning HVAC pipelines.
