Description

Technical Field

[0001] This utility model relates to the field of coffee pot technology, specifically to a dual-extraction coffee pot. Background Technology

[0002] With rapid socio-economic development and rising living standards, more and more people are enjoying coffee in their daily lives. Currently, the market is flooded with various instant coffee products. While convenient and quick, these often contain large amounts of artificial food additives, causing them to lose the original rich flavor of coffee and potentially posing health risks. Therefore, more and more coffee lovers prefer to brew their own coffee using a coffee maker for a more authentic and healthier drinking experience. Among the many types of coffee makers, the Americano coffee maker is particularly popular due to its ease of use and unique brewing method.

[0003] An Americano coffee maker, also known as a drip coffee maker, consists of three main parts: a hot water dispenser, a coffee grounds container, and a glass pot. To use this type of coffee maker, you first add an appropriate amount of coffee grounds to the container, then turn on the hot water dispenser, allowing hot water to slowly drip onto the coffee grounds. During the extraction process, the hot water dissolves the coffee's essence, and the extracted coffee then drips slowly into the glass pot below under gravity. Coffee made using this drip method has a relatively low concentration, which may not fully satisfy those who prefer a strong flavor. Furthermore, because the entire drip process takes time, an Americano coffee maker may not be suitable if you urgently need a cup of coffee to perk you up, as its relatively long brewing process doesn't provide a quick, hot cup. Therefore, we propose a dual-extraction coffee maker. Utility Model Content

[0027] In this embodiment, a contact silicone pad is fixedly connected to the upper end of the sealing baffle 9; the contact silicone pad increases the sealing between the sealing baffle 9 and the side retaining ring 5, and also reduces the wear between the sealing baffle 9 and the side retaining ring 5, thus extending the service life.

[0028] The working principle and usage process of this utility model are as follows: When in use, coffee powder is added to the coffee powder compartment 2, and the glass pot body 4 is inserted between the coffee powder compartment 2 and the electric heating base 3, so that the dispensing head 12 aligns with the connecting ball seat 11. Hot water is continuously dripped onto the upper part of the coffee powder compartment 2 by the hot water generator 1. The hot water flows through the coffee powder in the coffee powder compartment 2, extracting the coffee liquid, which then flows through the dispensing head 12 and the connecting ball seat 11, reaching the upper part of the receiving pot lid 10, and converging inside the glass pot body 4. Users who prefer strong coffee can pre-add water to the glass pot body 4, press the operating lever 17, and push the sealing baffle 9 downwards through the push rod sleeve 16, allowing water to enter the bottom of the glass pot body 4. Then, the sealing baffle 9 is pushed up by the reset force of the sealing compression spring 8, re-unsealing with the side retaining ring 5. During coffee making, the water at the bottom of the glass pot 4 is heated by the electric heating... The base 3 is heated to boiling, and the boiling water vapor increases the air pressure at the bottom of the inner cavity of the glass pot 4, forcing the boiling water at the bottom of the glass pot 4 through the connecting base 6. The squeezed boiling water is sent through the infusion riser 7 into the connecting hole 15 of the liquid outlet 12, and then sprayed above the coffee liquid through the water infusion riser 13 of the powder compartment. Since the extracted coffee liquid is concentrated at the upper end of the sealing baffle 9, when the pressure at the bottom of the sealing baffle 9 is less than the weight of the coffee liquid, the sealing compression spring 8 is compressed. The coffee liquid at the upper end of the sealing baffle 9 enters the bottom of the glass pot 4 through the gap between the side baffle ring 5 and the sealing baffle 9, and is repeatedly squeezed into the coffee powder compartment 2 to extract coffee multiple times, which increases the concentration of the extracted coffee liquid. For users who need to make coffee quickly, the double extraction of water supply drip filter from the hot water host 1 and hot water extraction pumped by the connecting base 6 greatly improves the coffee making speed.

[0029] By employing a dual extraction mechanism—combining hot water drip extraction and bottom boiling water spray extraction—the coffee grounds are more fully extracted, significantly increasing the concentration of the coffee liquid and satisfying the needs of coffee lovers who prefer a strong flavor. The extraction process is relatively efficient, with hot water dripping and boiling water spraying occurring simultaneously, greatly shortening the coffee-making time and allowing users to quickly obtain a cup of coffee when they urgently need it. The design of this invention is reasonable, and the tight fit between the components makes the coffee maker more stable and reliable during use.
