AI Technical Summary

Technical Problem

Traditional coffee machine funnel structures have relatively large components during disassembly, making them prone to dead corners during cleaning. The simple connection method can lead to water or steam leakage under high temperature and pressure, reducing the sealing effect.

Method used

Design a detachable coffee machine funnel structure, consisting of an upper funnel assembly, a middle funnel assembly, and a lower funnel assembly. Utilize components such as snap rings, levers, wedges, and inflatable seals to achieve individual disassembly and double sealing, ensuring no water leakage during high-pressure extraction.

Benefits of technology

It is easy to clean, avoids unsanitary corners, reduces usage costs, improves sealing performance, prevents coffee leakage, and enhances sealing effect under high temperature and pressure.
