[0004] To address the aforementioned technical problems, this utility model provides a beverage extraction device for a beverage extraction machine. It heats the liquid and ingredients with steam, achieving high and uniform steam temperature, shortening extraction time, and preventing damage to the ingredients. Simultaneously, an inner steaming chamber is suspended within an outer container by a support structure. The bottom of the inner steaming chamber has a liquid circulation mesh, forming an outer liquid space between the bottom and sides of the inner steaming chamber and the inner wall of the outer container, thus ensuring a clear path for liquid reflux and reducing component loss during beverage extraction. The internal and external placement of the inner steaming chamber and outer container saves space, resulting in a simple structure, low production cost, and convenient assembly and operation. The solution to the above technical problems is as follows:

[0005] A beverage extraction device for a beverage extraction machine includes an outer container with an open top, a support component, and an inner steaming chamber. The inner steaming chamber is placed inside the outer container via the support component. The inner steaming chamber includes a chamber body and a cover that is closed on top of the chamber body.

[0028] A beverage extraction device for a beverage extraction machine includes an outer container 10 with an open top, a support component 11, and an inner steaming chamber 12. The inner steaming chamber 12 is placed inside the outer container 10 via the support component 11, which is positioned between the inner steaming chamber 12 and the outer container 10, elevating the inner steaming chamber 12. The inner steaming chamber 12 includes a chamber body 121 and a cover 122 that fits over the top of the chamber body 121. The chamber body 121 and the cover 122 are detachably and sealed together via a threaded knob and a high-pressure sealing ring to form an inner steaming chamber 13. Both the outer container 10 and the inner steaming liner 12 are cylindrical. The outer container 10 has a boss extending upward from the center of its bottom. The diameter of the boss is smaller than the diameter of the inner steaming liner 121. The supporting component 11 is the boss. The inner steaming liner 12 is placed inside the outer container 10 through the boss. The internal and external arrangement between the inner steaming liner 12 and the outer container 10 saves space, has a simple structure, low production cost, and is easy to assemble and operate. The boss is integrally formed by extending upward from the center of the bottom of the outer container 10, which simplifies the production process and reduces the number of parts. The inner steaming chamber 13 can hold the raw materials and liquid solvents for beverage extraction. The raw materials can be medicinal herbs, food ingredients, etc., and the liquid solvents can be purified water, cooled boiled water, or alcoholic beverages, etc. The inner lid 122 is connected to a steam inlet pipe 14. Steam enters the inner steaming chamber 13 through the steam inlet pipe 14 to distill the raw materials. The steam temperature is high and the penetration is uniform, shortening the extraction time. The bottom of the inner body 121 has a liquid circulation mesh 15, providing a liquid inlet and outlet channel. The bottom and sides of the inner steaming chamber 12 form an outer liquid space 16 that can accommodate liquid flow between the inner surface and the inner wall of the outer container 10. The volume of liquid added to the inner steaming chamber 13 is smaller than the volume of the outer liquid space 16, and the volume of the inner steaming chamber 12 is 50% to 70% of the volume of the outer container 10. The central axis of the inner steaming chamber 12 and the center point of the protrusion are on the same axis. This design allows the inner steaming chamber 12 to be symmetrically placed within the outer container 10, ensuring even pressure distribution of the liquid during extraction and resulting in better extraction.

[0029] In use, the inner steam chamber 12 is placed inside the outer container 10 via a raised platform. The lid 122 of the inner steam chamber 12 is opened, and the raw materials (such as licorice, tea, coffee beans, or flowers) are placed into the inner steam chamber 13. Liquid (such as purified water) is added so that the liquid can cover the raw materials (the liquid volume is 50% of the total volume of the inner steam chamber 13). Then the lid 122 is closed tightly, and the raw materials are soaked for 1 hour. Steam is then introduced into the inner steam chamber 13 or directly into the inner steam chamber 13. As more and more steam is introduced into the inner steam chamber 13, the liquid is heated and the pressure on the liquid increases. This forces the liquid to flow out from the liquid circulation mesh 15 at the bottom of the inner steam chamber 13 into the outer liquid space 16. The liquid is heated by the steam and its temperature rises, and it also begins to generate vapor pressure. When the liquid is completely squeezed out of the inner steam chamber 13, the inner steam chamber 13 forms a closed space, and the raw materials are exposed to the liquid surface and come into contact with the steam, and are then distilled. High-temperature steam (100-120℃) rapidly penetrates the raw materials, disrupting cell wall structures and releasing intracellular flavor compounds (such as polyphenols and volatile oils). At this time, the steam flow rate into the inner distillation chamber 13 is kept constant, and the raw materials are distilled for 20-30 seconds. Then, the steam flow is stopped for 20-30 seconds, allowing the inner distillation chamber 13 to cool and generate negative pressure, causing the liquid to flow back from the outer liquid space 16 into the inner distillation chamber 13. Finally, the raw materials are once again submerged in liquid and continue to be soaked. This cycle is repeated 1 to countless times until the desired distillation effect is achieved. The combination of steam distillation and liquid reflux during the extraction process effectively reduces the loss of raw material components during beverage extraction. The liquid fully absorbs the trace elements / nutrients released by the ingredients, making absorption more effective and healthier for the body. For medicinal herbs, the distilled liquid is even more effective in treating diseases.

[0030] The outer container 10 of this invention has a liquid discharge device at its bottom, serving as a channel for dispensing beverages. The liquid discharge device is a beverage outlet pipe 19, which is connected to a filter screen for beverage filtration. A first switching valve 18 (such as a solenoid valve) is installed on the beverage outlet pipe 19 to control the dispensing of beverages. This design allows for timely sipation of beverages during or after extraction, facilitating confirmation of the extraction's effectiveness and the consumption of the beverage.

[0031] The liner 122 of this utility model is provided with an upper through hole 17, and the liner 122 is connected to the steam inlet pipe 14 through the upper through hole 17.

[0032] The steam inlet pipe 14 of this utility model is connected to a steam generator 20 at the other end, which is connected to the upper through hole 17. A second switch valve 21 is installed between the steam inlet pipe 14 and the steam generator 20. The entry of steam is controlled by opening or closing the second switch valve 21.

[0033] The first switching valve 18 and the second switching valve 21 of this utility model are mechanical check valves or electric valves.

[0034] The cap 122 of this invention is equipped with a pressure gauge at the top to monitor the pressure of the inner steam chamber 13 in real time. Based on the monitored pressure value, the steam flow rate can be predicted and adjusted in advance, thereby more accurately controlling the pressure of the outer liquid space 16 and the inner steam chamber 13.

[0035] The top opening of the outer liquid space 16 of this invention is detachably connected with a sealing ring cover to prevent dust or unidentified objects in the air from entering the outer liquid space 16 and to increase the range of steam thermal pressure that the outer liquid space 16 can withstand.
