A liquid injection coffee device

By designing a liquid-jet coffee maker, the coffee liquid is prepared through short-time contact within the filter housing using a liquid supply module and heating components. This solves the problem that existing coffee machines cannot fully utilize coffee beans, thus improving coffee quality and flavor.

AI Technical Summary

⚠Technical Problem

Existing coffee machines cannot fully utilize coffee beans and preserve coffee flavor simultaneously when preparing coffee. High-temperature steam extraction produces less coffee liquid, while repeated brewing may result in overly strong coffee liquid or the precipitation of bitter substances.

⚗Method used

A liquid-jet coffee device was designed. By setting a second chamber and a first chamber in the filter shell, the liquid in the first chamber is transferred to the second chamber by the liquid supply module. The liquid is sprayed onto the coffee beans and flows back through the drip hole, achieving short-time contact to prepare coffee liquid. The device is combined with a heating component and a stirring component to improve the coffee quality.

🎯Benefits of technology

This technology fully utilizes coffee beans, reduces the extraction of bitter substances, improves the quality and flavor of coffee, and meets the needs of office workers.
