Description

Technical Field

[0001] This utility model relates to the field of coffee extraction technology, and in particular to a high-efficiency extraction filter structure for coffee pots. Background Technology

[0002] As coffee culture becomes increasingly popular globally, consumers are demanding higher quality coffee. They not only crave rich flavors but also value clarity and a smooth texture. This has driven coffee maker manufacturers to continuously improve filter structures to achieve more efficient extraction, preserve the aroma and flavor compounds, and minimize residue. A coffee maker is a tool that mixes and extracts coffee grounds and water to create a coffee beverage. Different types of coffee makers—drip makers, espresso machines, and French presses—use different extraction methods to produce a variety of flavors and textures, satisfying diverse taste preferences. For coffee lovers, owning a coffee maker allows them to make coffee at home anytime, saving time and money. Furthermore, modern coffee makers are easy to operate, multifunctional, and can quickly produce delicious coffee, adapting to fast-paced lifestyles.

[0003] The filter structure of a coffee maker plays a crucial role in the coffee-making process. Because the filter structure optimizes the extraction process, making extraction more efficient, high-quality coffee can be made in a shorter time. The filter structure in an espresso machine, through high-pressure extraction and a fine filter design, can extract a rich coffee concentrate in a short time, saving preparation time and improving coffee-making efficiency. However, with repeated use, the filter can become clogged with coffee grounds, causing the coffee liquid to filter more slowly or even fail to filter properly. This not only affects brewing efficiency but also results in insufficient extraction of the coffee, reducing its quality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency extraction filter structure for coffee pots, aiming to improve the problem in the prior art where the filter screen of the filter cartridge gets clogged with coffee grounds with increasing use, resulting in slower coffee filtration speed or even failure to filter properly. This not only affects brewing efficiency but also causes insufficient extraction of coffee, reducing coffee quality.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency extraction filter structure for a coffee pot, comprising a conical shell, a support ring fixedly connected to the top of the conical shell, two grooves being formed at the top of the support ring, two fixing blocks fixedly connected to the front and rear sides of the support ring, U-shaped blocks rotatably connected between adjacent fixing blocks, a rotating shaft rotatably connected to the middle of each U-shaped block, a U-shaped buckle fixedly connected to the top of the rotating shaft, a filter cartridge installed on the inner wall of the conical shell, L-shaped frames fixedly connected to the front and rear sides of the top of the filter cartridge, the bottom of the L-shaped frames engaging with the top of the grooves, and an extraction mechanism provided on the inner side of the conical shell, the extraction mechanism being used to improve extraction efficiency.
