[0070] In the embodiment, the first composite bin 22 forms the independent first liquid outlet bin 221 and the first powder bin 222 through the three-dimensional separation of the internal first spacer group 23.

The top of the first water storage compartment 31 is equipped with a first water outlet piece 32 with a first pipeline 321 and a first partition layer 322, forming a detachable water channel.

[0072] In operation, the first heating module 42 heats the water in the water storage compartment to a preset temperature, and then the first high-pressure gas pump 41 injects compressed gas into the compartment, forcing the water to flow through the first pipeline 321 into the first partition layer 322, and then penetrating the coffee powder layer through the dispersion structure of the first spacer group 23 to complete high-pressure extraction.

The threaded or screw connection of the upper shell 5 and the lower shell 6 ensures the air tightness during pressurized extraction. The second extraction assembly 7 is precisely separated by the second set of partitions, which forms independent cavities in the second powder chamber to prevent powder residue from leaking. The second water storage assembly is connected to the second composite chamber 71 through a water channel, and cooperates with the second high-pressure air pump 81 and the second electromagnetic valve of the second control assembly 8 to form a controllable pressure system, which forces the water flow to uniformly penetrate the coffee powder layer, improving the extraction efficiency and flavor extraction. The second water outlet piece is connected to the second water storage chamber and the second partition through the second pipeline. The horizontally arranged partition optimizes the water flow path, allowing pressure to uniformly penetrate the powder layer surface, avoiding local over-extraction or channeling effects, and ensuring stable coffee liquid quality.

[0090] In some embodiments, the inner wall of the second composite chamber 71 is provided with a third flange, the second set of partitions includes a second water distribution piece 72 and a second filter screen, the second water distribution piece 72 is arranged on the third flange, the lower side of the second water distribution piece 72 is the second powder chamber, and the upper side of the second water distribution piece 72 is the second water storage chamber. The second filter screen is arranged below the second powder chamber, and the second filter screen is arranged towards the direction of the liquid outlet cup.

[0091] In the embodiment, the third flange of the inner wall of the second composite chamber 71 is a ring-shaped protruding structure for supporting the second water distribution piece 72 and limiting its horizontal position. The second water distribution piece 72 is placed on the third flange, and the second powder chamber is formed below the second water distribution piece 72 to load the coffee powder compacted by the powder hammer. During operation, the second filter screen is loaded into the bottom of the second composite chamber 71, coffee powder is added and compacted, then the second water distribution piece 72 is loaded and water is injected, and the upper and lower shells 6 are sealed and fixed by threaded or screw connection. The second water distribution piece 72 uniformly disperses the water flow through the micro-holes, and the second filter screen intercepts the coffee powder residue, and the two cooperate to achieve liquid-solid separation.

[0092] The embodiment precisely positions the second water distribution piece 72 through the third flange, ensuring the physical isolation of the second powder chamber. Combined with the flow guiding effect of the second water distribution piece 72 and the interception function of the second filter screen, the powder is prevented from entering the liquid outlet path. The sealing structure maintains the pressure stability during pressurized extraction, and the layered arrangement of the second water distribution piece 72 and the second filter screen optimizes the uniformity of water flow penetration, while simplifying the disassembly process and improving the operation efficiency and extraction consistency.

[0093] In some embodiments, the second control assembly 8 further includes a panel 83 and a second battery 84. The panel 83 is arranged on the top of the upper shell 5, and the panel 83 is configured as at least one of a touch panel, a key panel, and a display screen. The second control unit 82 is electrically connected to the panel 83. The second battery 84 is electrically connected to the second control unit 82.

[0094] In the embodiment, the user interaction convenience is enhanced by configuring the panel 83 containing a touchpad, a key panel or a display screen on the top of the upper shell 5, the second control unit 82 is electrically connected with the panel 83 to realize accurate response of operation instructions. The second battery 84 is integrated with the second control unit 82 for power supply, ensuring that the coffee machine can still operate stably without external power supply, and improving the flexibility of use scenarios. The multifunctional configuration of the panel 83 supports intuitive operation and state feedback, and the second control unit 82 coordinates the opening and closing of the second high-pressure air pump 81 and the second electromagnetic valve and pressure regulation, ensuring the controllability of the extraction process. The introduction of the second battery 84 optimizes the compactness of the overall structure, avoids the interference of external power lines, and at the same time, the layout of the panel 83 and the battery takes into account the ergonomics and internal space utilization, strengthening the portability of the coffee machine and the consistency of user experience.

[0095] In some embodiments, the coffee machine further comprises a second upper support and a second lower support, the second upper support is arranged in the upper shell 5, and the second upper support is arranged above the second control assembly 8; the second lower support is arranged in the upper shell 5, and the second upper support is arranged above the second water storage assembly, and the second control assembly 8 is arranged between the second lower support and the second upper support.

[0096] In the embodiment, by arranging the second upper support and the second lower support in the upper shell 5, the structural stability and component positioning accuracy are enhanced. The second upper support is above the second control assembly 8, and the second lower support is above the second water storage assembly, and the two form a layered support frame, so that the second control assembly 8 and the second water storage assembly realize modular layout inside the shell. The second control assembly 8 is limited between the second upper support and the second lower support, avoiding displacement or vibration interference during operation, while optimizing the internal space utilization of the shell. The support structure disperses the mechanical stress during pressure extraction, reduces the risk of shell deformation, and reduces heat conduction or liquid gas penetration between the second control assembly 8 and the second water storage assembly through physical isolation, improving the reliability and long-term stability of the whole machine.

[0097] Further, the following examples can be developed in combination with the above technical solutions:

[0098] The product is mainly composed of a cover and a powder hammer (i.e., the cover plate 21 and the first powder hammer 211), a liquid outlet bin and a powder bin (i.e., the first liquid outlet bin 221 and the first powder bin 222), a filter screen (i.e., the first filter screen 232), a water distribution piece (i.e., the first water distribution piece 231), a water outlet piece group (i.e., the first water outlet piece 32), a water bin (i.e., the first water storage bin 31), a heating module (i.e., the first heating module 42), a temperature measurement module (i.e., the first temperature measurement module 47), a high-pressure air pump (i.e., the first high-pressure air pump 41), a battery pack (i.e., the first battery 45), a solenoid valve (i.e., the first solenoid valve 44), a circuit board (i.e., the first control unit 43), and other silica gel connecting pipes. Many products on the market do not use a water distribution piece. When coffee is extracted, the middle powder is excessively extracted, and the surrounding extraction is insufficient. The function of the water distribution piece is to disperse the water (like a shower) to achieve full and uniform extraction. The water outlet piece group is composed of a water outlet piece and a sealing element.

[0099] Scheme One

[0100] 1. The liquid outlet bin (i.e., the first liquid outlet bin 221) and the powder bin (i.e., the first powder bin 222) are filled with the filter screen (i.e., the first filter screen 232) to separate the liquid outlet bin and the powder bin. The powder bin (i.e., the first powder bin 222) is filled with coffee powder, and the cover (i.e., the cover plate 21) and the powder hammer (i.e., the first powder hammer 211) are used to compact the coffee powder. The water distribution piece (i.e., the first water distribution piece 231) is installed.

[0101] 2. The water bin (i.e., the first water storage bin 31) is filled with water, and then the water outlet piece group (i.e., the first water outlet piece 32) is installed. The components (i.e., the first extraction assembly 2) are sealed and assembled by means of a toothed pattern or a buckle.

[0102] 3. The heating module (i.e., the first heating module 42) heats the water in the water bin (i.e., the first water storage bin 31), and the temperature measurement module (i.e., the first temperature measurement module 47) controls the water temperature. After the water temperature reaches the set value, the high-pressure air pump (i.e., the first high-pressure air pump 41) works, and the water bin (i.e., the first water storage bin 31) is inflated. The water is pressed out of the water outlet piece (i.e., the first water outlet piece 32) by using air pressure. The water passes through the water distribution piece (i.e., the first water distribution piece 231) to soak the coffee powder, and then passes through the filter screen (i.e., the first filter screen 232) to achieve high-pressure perfect coffee extraction.

[0103] 4. The solenoid valve (i.e., the first solenoid valve 44) is used to release the pressure in the water bin (i.e., the first water storage bin 31), thereby facilitating the disassembly of the components (i.e., the first extraction assembly 2) and the water bin (i.e., the first water storage bin 31).

[0104] Scheme Two

[0105] 1. A filter screen (i.e., first liquid outlet 221) is installed in the liquid outlet (i.e., first liquid outlet 221) and the powder outlet (i.e., first powder outlet 222) to separate the liquid outlet and the powder outlet. Coffee powder is loaded into the powder outlet (i.e., first powder outlet 222) and compacted with a lid (i.e., lid plate 21) and a tamper (i.e., first tamper 211). A water separator (i.e., first water separator 231) is then installed.

[0106] 2. Water is filled into the water tank (i.e., the first water storage tank 31), and then the water outlet plate group (i.e., the first water outlet plate 32) is installed. The components (i.e., the first extraction component 2) are sealed and assembled by means of threads or buckles.

[0107] 3. The high-pressure air pump (i.e., the first high-pressure air pump 41) operates, pumping air into the water tank (i.e., the first water storage tank 31), using air pressure to force water out from the water outlet plate (i.e., the first water outlet plate 32), the water passes through the water separator plate (i.e., the first water separator plate 231) to soak the coffee powder, and passes through the filter screen plate (i.e., the first filter screen plate 232) to achieve high-pressure perfect extraction of coffee liquid.

[0108] 4. The pressure in the water tank (i.e., the first solenoid valve 44) is released by using a solenoid valve, thereby facilitating the separation of the component (i.e., the first extraction component 2) from the water tank (i.e., the first water tank 31).

[0109] In this solution, the coffee machine is not responsible for heating. Adding boiling water will achieve hot brewing of coffee, while adding room temperature water will achieve cold brewing of coffee.

[0110] Option 3:

[0111] The high-pressure air outlet assembly (i.e., the second control assembly 8) consists of an upper body (i.e., the upper housing 5), a high-pressure air pump (i.e., the second high-pressure air pump 81), a battery pack (i.e., the second battery 84), an electronic control board (i.e., the second control unit 82), and a panel 83.

[0112] Working process description: The extraction cup (i.e., the second compound chamber 71) is fitted with a filter screen (i.e., the second filter screen), ground coffee powder is added, the coffee powder is tampd down with a tamper, a water separator (i.e., the second water separator 72) is installed, and water is added. The lower body (i.e., the lower housing 6) and the upper body (i.e., the upper housing 5) are sealed and fixed to the extraction cup (i.e., the second compound chamber 71) via screws or clips. The high-pressure air pump (i.e., the second high-pressure air pump 81) operates, pressurizing the extraction cup (i.e., the second compound chamber 71), causing the water in the extraction cup (i.e., the second compound chamber 71) to flow out through the coffee powder under pressure, completing the coffee extraction process.

[0113] By adopting the above technical scheme, the utility model differs from the prior art and has the following beneficial effects: the utility model realizes comprehensive improvement of coffee extraction efficiency, equipment reliability and convenient maintenance through modular structure design and collaborative function layout.
