AI Technical Summary

Technical Problem

In existing humidification processes, when the humidification tank device malfunctions, water can easily backflow into the gas source pipeline, damaging the main equipment and causing malfunctions, and there is a lack of effective protective measures.

Method used

A multi-stage backflow prevention protection device for a humidifier tank was designed, including a backflow prevention gas storage tank, an air inlet assembly, a drainage assembly, an air guide assembly, and an air outlet assembly. It employs a one-way check valve, a solenoid valve, a manual valve, and a liquid level sensor to form multiple layers of protection to ensure that water does not flow back.

Benefits of technology

It effectively prevents water backflow in the humidification tank, reduces initial risks, promptly closes the valve to cut off the backflow path, provides early warning and drainage protection, and ensures the safe and stable operation of the device.
