Description

Technical Field

[0001] This utility model relates to the field of coffee extraction, specifically an integrated coffee powder pressing and extraction structure. Background Technology

[0002] Coffee extraction involves controlling the contact conditions between water and coffee grounds to extract soluble substances (such as caffeine, oils, and organic acids) into a coffee liquid. However, existing coffee extraction equipment requires pressure extraction, resulting in insufficient structural integration and a large overall structure. Furthermore, the fixed tamper design prevents rotation and is prone to jamming. Therefore, those skilled in the art have developed an integrated coffee grounds distribution, tampering, and extraction structure to address the problems mentioned in the background section.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3In this embodiment of the invention, the integrated coffee powder pressing and extraction structure includes a high-pressure extraction chamber support 10 and a spiral push block 8. A high-pressure steam nozzle 9 is fixedly connected to the top of the high-pressure extraction chamber support 10. A stainless steel fixing plate 5 is connected to the middle of the top of the high-pressure extraction chamber support 10 by screws. A slider guide sleeve 4 is fixedly connected to the middle of the top of the stainless steel fixing plate 5. A spiral slider 3 is slidably arranged inside the slider guide sleeve 4. A screw rod 2 is threadedly connected to the outer periphery of the spiral push block 8. A motor 1 is installed at the top of the screw rod 2. A retainer 17 is slidably connected to the middle of the stainless steel fixing plate 5. A bearing is installed inside the retainer 17. 11. A stainless steel internal threaded post 13 is provided at the inner ring of the bearing 11. A spiral push block 8 is provided around the stainless steel internal threaded post 13. A sealing silicone 12 is fixedly connected to the bottom of the spiral push block 8. A breathable powder pressing plate 15 is connected to the bottom of the stainless steel internal threaded post 13 by screws. An annular sealing silicone ring 14 is clamped around the lower periphery of the high-pressure extraction chamber support 10. A coffee powder cup 16 is provided below the sealing silicone ring 14. A bowl-shaped extraction filter screen 18 is placed above the coffee powder cup 16. The annular sealing silicone ring 14 can provide a seal for the installation of the coffee powder cup 16, which facilitates the subsequent coffee extraction operation.

[0018] Among them, a spring 7 located on the periphery of the stainless steel internal thread post 13 is clamped between the upper and lower spiral push blocks 8 below the card holder 17, and a two-tooth spiral connector 6 is provided at the bottom end of the screw 2.

[0019] The bottom end of the two-toothed spiral connector 6 is connected to the stainless steel internal thread post 13 by a thread, and the two-toothed spiral connector 6 of the card seat 17 is fixed above the stainless steel internal thread post 13.

[0020] By adopting the above technical solution, the motor 1 can be started to drive the screw 2 to rotate. Under the threaded transmission, the spiral slider 3 can be pushed to move downward under the guidance of the slider guide sleeve 4. Then, the spiral slider 3 pushes the card seat 17 to move downward through the stainless steel internal thread column 13. The stainless steel internal thread column 13 moves synchronously with the breathable powder pressing plate 15. The breathable powder pressing plate 15 performs the pressing and extraction operation on the coffee. After the extraction is completed, the motor 1 reverses to release the force. Under the action of the spring 7, it can act in the opposite direction on the breathable powder pressing plate 15 to make it rebound and release the force. This structure integrates the power component and the pressurizing extraction component into one, making the structure more compact and convenient for use in small spaces. Moreover, by setting the spring 7 to provide the extraction rebound force and setting the breathable powder pressing plate at the bottom of the bearing 11 to provide rotational support, it can be ensured that the breathable powder pressing plate can rotate and press the coffee at will without jamming, which is extremely practical.

[0021] The output shaft of the motor 1 is integrally formed with the screw 2, the guide hole of the slider guide sleeve 4 is a waist-shaped structure, and the side wall of the spiral slider 3 is formed with a parallel plane for guidance, which can ensure that the slider guide sleeve 4 can provide guidance for the spiral slider 3 to move up and down.

[0022] The top of the card holder 17 is in contact with the bottom of the spiral slider 3 under the elastic support force of the spring 7. A high-pressure steam nozzle 9 is integrally formed on the high-pressure extraction chamber support 10 and communicates with the internal cavity of the high-pressure extraction chamber support 10. The high-pressure steam nozzle 9 is connected to the external high-pressure steam delivery pipeline.

[0023] The working principle of this utility model is as follows: Before use, the external high-pressure steam delivery pipeline needs to be connected to the high-pressure steam nozzle 9. During use, the coffee powder cup 16 containing coffee is placed below the high-pressure extraction chamber support 10. By rotating the coffee powder cup 16, it can be installed by the buckle on the side of the coffee powder cup being snapped into the buckle below the high-pressure extraction chamber support 10. The bowl-shaped extraction filter 18 built into the coffee powder cup 16 can play the role of extraction and filtration. Then, the motor 1 is started, driving the screw 2 to rotate. Under the screw drive, the spiral slider 3 can be pushed downward under the guidance of the slider guide sleeve 4, and then the spiral slider 3 pushes the clip... The seat 17 connects to the stainless steel internal threaded column 13, which moves downwards. The stainless steel internal threaded column 13 moves synchronously with the breathable powder pressing plate 15, which performs the pressing and extraction of coffee. After extraction, the motor 1 reverses to release the force. Under the action of the spring 7, it can act in the opposite direction on the breathable powder pressing plate 15 to make it rebound and release the force. This structure integrates the power component and the pressurizing extraction component, making the structure more compact and convenient for use in small spaces. Moreover, by setting the spring 7 to provide the extraction rebound force and by setting the bearing 11 at the bottom of the breathable powder pressing plate to provide rotational support, it can be ensured that the breathable powder pressing plate can rotate and press coffee at will without jamming, which is extremely practical.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
