Detailed Implementation

[0020] like Figures 1 to 11The following describes a beverage extraction device, which is a partial internal component of an electric beverage extraction machine. It includes an inner tank 1 and an outer tank 2, both made of stainless steel and circular in shape. The diameter of the outer tank 2 is less than 30 cm, and the diameter of the inner tank 1 is less than 28 cm. The height of the inner tank 1 and outer tank 2 is less than 30 cm. The inner tank 1 includes a body 101 and a cap 102. The top opening of the body 101 is openably and sealingly connected to the cap 102. A soft rubber sealing ring connects the cap 102 to the top of the body 101 for sealing after closing. Preferably, the cap 102 and the top of the body 101 are sealed together. The inner liner 1 and outer liner 2 are fixed together by a threaded connection, and sealed with a soft rubber sealing ring after tightening. The outer liner 2 is open to the outside air. The interior of the inner liner 1 is the food steaming chamber 11, which is used to place food for steaming. Foods include: Chinese medicinal herbs, flower tea, prepared Chinese medicine, health tea, health nutrients, solid beverages, etc. The interior of the outer liner 2 is the liquid storage chamber 21, which is open and used to store water or beverage liquids. The inner liner 1 is installed inside the liquid storage chamber 21 of the outer liner 2. The top of the inner liner 1 is slightly lower than, level with, or slightly higher than the opening of the liquid storage chamber 21. The cavity opening; the inner liner 1 and the outer liner 2 can be detachably or fixedly connected; a spaced surrounding groove 3 is formed between the inner liner 1 and the outer liner 2, which provides liquid flow space, temporary liquid flow storage space, and liquid level difference between the inside and outside during beverage extraction, so as to facilitate uniform liquid flow and mixing, and facilitate the absorption of trace elements and nutrients released by the ingredients; the bottom or bottom side wall of the inner liner 1 is provided with water holes 12 and connected to the liquid storage cavity 21, and there are several water holes 12, the diameter of which is generally less than 2 mm, and they are distributed in a mesh pattern; preferably, the water holes 12 are provided at the bottom of the inner liner 1, so that steam and... The liquid has a longer contact time, the steam travels a longer path, and the liquid more effectively absorbs the trace elements and nutrients released by the food. A steam input device 4 is jointly provided at the bottom of the inner pot 1 and the bottom of the outer pot 2. External steam enters the food steaming chamber 11 through the steam input device 4. This steam input device 4 facilitates steam entry from the bottom, has sufficient space for installation, and is rationally positioned to utilize the available space for convenient steam input into the steamed food. Simultaneously, the pot body 101 has an openable lid 102 at the top for easy placement of food, removal of food residue, and cleaning of the pot body 101 and lid 102. This product has a small overall size. The product has a simple structure, is easy to extract beverages, easy to clean, low in cost, and convenient for users to use.

[0021] In use, open the inner cap 102, place the ingredients into the food steaming chamber 11 through the top opening of the inner cap 101, and then add an appropriate amount of water, ensuring the water level is higher than the water inlet 12 and submerges the ingredients. The water levels in the storage chamber 21 and the food steaming chamber 11 should be level immediately after adding water. Then, screw the inner cap 102 to seal the inner cap 101. Start the electric beverage extractor; the steam generator will produce steam. The steam enters the food steaming chamber 11 through the steam input device 4. When the steam pressure in the food steaming chamber 11 is greater than the water pressure, the steam pressure forces the water in the food steaming chamber 11 through the water inlet 12 to the spaced surrounding groove 3. The steam begins to steam the ingredients. Since the steam contains moisture, the ingredients begin to cook. Trace elements and nutrients in the ingredients are released and flow away with the steam. The steam mixes with the water in the storage chamber 21, and the water absorbs the trace elements and nutrients from the steam, thus forming a beverage. The process involves steaming ingredients, where air and water mixed to form bubbles that flow, rise to the surface, and then burst. After steaming the ingredients for a period of time (e.g., 10 minutes), the electric beverage extractor stops its steam generator (e.g., stops for 20 minutes). No steam is generated, the inner tank 1 cools down, the food steaming chamber 11 condenses, and water from the outer spacer surrounding the tank 3 flows back through the water outlet 12 into the food steaming chamber 11 to soak the ingredients. Then, the electric beverage extractor restarts its steam generator to continue steaming the ingredients. After repeating this process several times, the flavor, trace elements, and nutrients of the ingredients are essentially released, dissolving in the water to obtain the desired beverage. Of course, if some ingredients are deemed insufficient for distillation in one pass and require secondary distillation to extract trace elements and nutrients, secondary distillation can be performed following the above steps to maximize utilization and avoid waste.

[0022] Preferably, a support device 5 is provided between the inner liner 1 and the outer liner 2. The support device 5 raises the inner liner 1. An isolation space 51 is formed between the outer bottom wall of the inner liner 1 and the inner bottom wall of the liquid storage cavity 21 of the outer liner 2. The isolation space 51 cooperates with the water passage hole 12 opened at the bottom of the inner liner 1. The isolation space 51 provides enough space for water to flow back and forth between the inside and outside, preventing the bottom of the inner liner 1 from sticking tightly to the bottom wall of the liquid storage cavity 21 and preventing obstruction of water flow.

At the bottom, the inner section of the first steam input pipe 41 is arranged to form the bottom of the liquid storage chamber 21, and the outer section of the first steam input pipe 41 is arranged to form the bottom of the outer liner 2. When the inner liner 1 is placed into the liquid storage chamber 21, the inner section of the first steam input pipe 41 is inserted into the bottom opening of the second steam input pipe 42. External steam is input from the first steam input pipe 41, then enters the second steam input pipe 42, and then sprays out from the steam outlet 421, which sprays out into the food steaming chamber 11 to steam the food. The above-mentioned steam input device 4 is easy to disassemble and place the inner liner 1 for use. Its structure is simple, easy to connect, and has a good steam transmission effect.

[0026] Preferably, a sealing element 43 is fixed between the inner section of the first steam input pipe 41 and the inner wall of the pipe hole of the second steam input pipe 42 to prevent steam from leaking out from the gap between them and directly entering the liquid storage chamber 21, so that the steam can completely pass through the second steam input pipe 42, thereby improving the sealing effect. At the same time, it also prevents the liquid in the liquid storage chamber 21 from leaking back into the first steam input pipe 41 from the gap between them. The sealing element 43 is a rubber sealing ring with good sealing performance. The rubber sealing ring is a rubber sealing ring or a silicone sealing ring with good sealing performance.

[0027] Preferably, the second steam inlet pipe 42 extends upwards close to the inner top of the food steaming chamber 11, and steam is ejected from the top, which is more effective for steaming food and more effective for compressing the water level difference.
