Description

Technical Field

[0001] This invention relates to the field of beverage preparation equipment technology, specifically to a beverage preparation liquid circuit system, a brewing and residue removal system, and beverage preparation equipment. Background Technology

[0002] Existing beverage preparation equipment, such as coffee machines, typically uses a double-opening, double-piston brewing assembly. In this configuration, one piston forms the water inlet channel, and the other forms the liquid outlet channel. When brewing or removing sediment, the external liquid is usually introduced through the water inlet channel. Furthermore, when the brewing cylinder needs to be moved, the upper piston can detach from the cylinder, while the lower piston remains inside and moves with the cylinder, minimizing interference. However, this design obviously increases overall structural complexity and results in a larger vertical dimension, leading to a larger vertical space requirement. Summary of the Invention

[0039] In addition, to achieve the above objectives, the present invention also provides a beverage preparation device, including the brewing and slag removal system described above.

[0040] In the technical solution provided by this invention, the cylinder body has only one opening and a single piston, which helps to avoid the complexity and increased weight of a double-opening, double-piston structure. This results in a more compact overall structure and less space occupation, which helps to achieve the miniaturization of the entire brewing unit, allowing it to be widely used in various models. Furthermore, to a certain extent, the single-opening, single-piston design simplifies the hydraulic system of the entire machine, enabling rapid response and high-efficiency conversion, thereby significantly improving the efficiency of beverage preparation.

[0041] Different connecting pipes can provide different external media, thus meeting the different needs of the brewing unit. For example, when the brewing unit is operating in its preparation mode, the required external hot water is connected through a connecting pipe and a corresponding connecting pipe. Or, for example, when the brewing unit is operating in its cleaning mode, the required room temperature clean water, external hot water, and / or external steam are connected through another connecting pipe and a corresponding connecting pipe.

[0042] The cylinder body has one and only one connecting pipe. Connecting and adapting to different connecting pipes through the same connecting pipe helps simplify the overall structure of the cylinder body, thereby ensuring the overall strength of the cylinder body and reducing the molding and movement burden on the cylinder body, which in turn helps improve the overall reliability of the machine.

[0052] First application example: Please see Figures 1 to 7 This invention provides a beverage preparation system and its applicable beverage preparation equipment.

[0053] It is understandable that this beverage making equipment can be used to brew any suitable powder or other solid material to make beverages.

[0054] Beverage-making equipment generally also includes a housing. The beverage-making liquid circuit system is at least partially built into the housing. For ease of understanding, the following embodiments are illustrated using an example where the beverage-making equipment as a whole has two intersecting horizontal, vertical, and longitudinal axes. In practical applications, the horizontal, vertical, and longitudinal axes can be perpendicular or nearly perpendicular to each other. Furthermore, the vertical axis can specifically correspond to the direction of gravity, while the horizontal and longitudinal axes roughly correspond to any two horizontal directions on the horizontal plane.

[0055] Therefore, the beverage preparation system includes at least a brewing unit. Specifically, the brewing unit may include a cylinder 1-100, a piston assembly, and a media assembly.

[0056] The cylinder block 1-100 has an opening 1-110 at one end of its axis.

[0057] The piston assembly includes a piston element-210 and a drive mechanism 1-220. The drive mechanism 1-220 and the piston element-210 are driven together so that the piston element-210 can freely enter and exit the cylinder body 1-100 through the opening 1-110 under the drive of the drive mechanism 1-220.

[0058] The media assembly includes at least two connecting lines. Each connecting line is used to supply an external medium. Therefore, one end of each connecting line is used to connect directly or indirectly to an external medium source. Furthermore, the external media flowing through the at least two connecting lines are different.

[0059] The cylinder body 1-100 has a connecting pipe 1-120 on its outer wall that connects the inside and outside of the cylinder body 1-100. The same connecting pipe 1-120 is used to adapt and connect different connecting pipes, and after connection, the corresponding external medium is introduced into the cylinder body 1-100.

[0060] In the technical solution provided by this invention, the cylinder body 1-100 has only one opening 1-110, and is equipped with a single piston component-210. This helps to avoid the complexity and weight increase of a double-opening, double-piston structure, resulting in a more compact overall structure and less space occupation. This contributes to the miniaturization of the entire brewing unit, allowing it to be widely used in various models. Furthermore, to a certain extent, the single-opening 1-110 and single-piston component-210 design simplifies the hydraulic system of the entire machine, enabling rapid response and high-efficiency conversion, thereby significantly improving the efficiency of beverage preparation.

[0061] Different connecting pipes can provide different external media, thus meeting the different needs of the brewing unit. For example, when the brewing unit is operating in its preparation mode, the required external hot water is connected to it via a connecting pipe and the corresponding pipe 1-120. Or, for example, when the brewing unit is operating in its cleaning mode, the required room temperature clean water, external hot water, and / or external steam are connected to it via another connecting pipe and the corresponding pipe 1-120.

[0062] There is one and only one connecting pipe 1-120 at cylinder 1-100. Connecting and adapting different connecting pipes through the same connecting pipe 1-120 helps to simplify the overall structure of cylinder 1-100, thereby ensuring the overall strength of cylinder 1-100 and reducing the molding and movement load on cylinder 1-100, which in turn helps to improve the overall reliability of the machine.

[0063] In this design, the connecting pipe 1-120 is disposed on the cylinder body 1-100, and generally, to prevent interference with the entry and exit of the piston component-210, the connecting pipe 1-120 and the opening 1-110 are spaced apart. Specifically, for example, one end of the cylinder body 1-100 forms the opening 1-110, and the end directly opposite the opening 1-110 constitutes the cylinder bottom. The cylinder body 1-100 also includes a cylinder side portion connecting the cylinder bottom and the end where the opening 1-110 is located.

[0064] At this point, the connecting pipe 1-120 can be located at the bottom of the cylinder. Alternatively, the connecting pipe 1-120 can be located on the side of the cylinder. Generally, in order to facilitate the formation of a relatively uniform and stable water flow pressure on the powder cake during brewing, the connecting pipe 1-120 is usually located at the bottom of the cylinder, fully spaced from the opening 1-110, and positioned approximately opposite to the piston component-210 that extends into the cylinder body 1-100 through the opening 1-110.

[0065] The connecting pipe 1-120 can be installed with its protrusion outward relative to the cylinder wall at its location. Alternatively, it can be installed with its protrusion inward relative to the cylinder wall at its location. Of course, depending on actual needs, the connecting pipe 1-120 can also be roughly flush with the cylinder wall at its location. The specific structure can be adjusted to suit the specific structure of the connecting pipes and the connection method between the two.

[0066] Pipeline 1-120 is configured with a connecting channel extending along its length. This connecting channel connects the inside and outside of cylinder body 1-100. This connecting channel can be configured as a normally open channel, i.e., maintaining a continuous state. Alternatively, the connecting channel can be configured to be switchable. For example, it may include a valve body, an opening / closing cover, etc., allowing the connecting channel to be in a continuous or disconnected state by operating the valve body, opening / closing cover, etc.

[0067] The connecting pipes are located on the side of cylinder 1-100. Specifically, for example, the beverage preparation system also includes a mounting bracket. The mounting brackets are spaced apart on the side of cylinder 1-100, and their orientation is basically fixed. The connecting pipes are located at the mounting brackets.

[0068] The connecting pipe is configured to have a connecting channel extending along its length. One end of the connecting pipe is directly or indirectly connected to an external medium source. The other end of the connecting pipe is exposed to allow for fitting and connection with the docking pipe 1-120. After connection, the connecting channel communicates with the docking channel, forming a complete flow path from the external medium source, through the connecting channel and the docking channel, to the cylinder body 1-100.

[0069] Similarly, the connection channel can be configured as a normally open channel structure, i.e., maintained in a conductive state. In this case, for example, the on / off state of the flow path can be controlled by setting an on / off switch at an external medium source. Specifically, a pump body can be installed at the external medium source or at any location within the flow path. The pump body implements the aforementioned on / off control.

[0070] Alternatively, the connection channel can be configured to be on / off. For example, it can be equipped with a valve body, an opening and closing cover, etc., which can be operated to make the connection channel have a conducting state and an isolated state. The above-mentioned flow channel is only opened when the external medium source, the connection channel, and the docking channel are all in the conducting state.

[0071] There are at least two connecting pipes. And the external medium flowing through at least two points in each connecting pipe is different.

[0072] For example, when there are three or more connecting pipes, each connecting pipe can carry a different external medium. Alternatively, some of the connecting pipes can carry the same external medium.

[0073] The different forms of external media can take many forms, such as different temperatures, flow rates, compositions, and properties. However, it's important to note that different external media do not constitute a limitation on the external media source. For example, when different connecting pipes are connected to the same external media source, the external media output from that source can appear different due to the influence of at least one connecting pipe. Specifically, this could mean different flow rates, temperatures, etc., of the external media output from the same external media source.

[0074] The specific form of the external medium source is not limited. For example, it can be, but is not limited to: The drinking water system may also include a hot water module. This hot water module may include a hot water boiler 1-410 and a heater. After sufficient liquid is supplied to the hot water boiler 1-410, the heater heats the liquid to the desired temperature, forming hot water. The hot water is stored within the hot water boiler 1-410.

[0075] The liquid preparation system may also include a steam module. This steam module may include a steam boiler 1-420 and a heating and pressurizing unit. After sufficient liquid is supplied to the steam boiler 1-420, the heating and pressurizing unit heats the liquid to the desired temperature and pressure, forming high-temperature steam. This high-temperature steam can be stored within the steam boiler 1-420.

[0076] The beverage preparation system may also include a gas storage module. This gas storage module may include a gas tank and a pressure regulator. When needed, the pressure regulator can adjust the gas in the gas tank to output a preset pressure.

[0077] In this application, such as Figure 5 As shown, specifically, the beverage preparation system may include a hot water module and a steam module as described above. Correspondingly, each connecting pipe includes a first connecting pipe 1-310 and a second connecting pipe 1-320. The first connecting pipe 1-310 is connectable to the hot water boiler 1-410. The second connecting pipe 1-320 is connectable to the steam boiler 1-420.

[0078] Beverage-making equipment and / or beverage-making liquid circuit systems generally have a pre-programmed, editable preparation mode. The purpose of operating this preparation mode is to prepare beverages from, for example, powder. Therefore, in the preparation mode, the drive mechanism 1-220 drives the piston-210 through the opening 1-110 into the cylinder 1-100 and moves it to the target position, so as to press the powder already received in the cylinder 1-100 into a cake of the target thickness.

[0079] At this time, the first connecting pipe 1-310 can be connected to the connecting pipe 1-120. It also connects to the hot water flow path from the hot water boiler 1-410, through the first connecting pipe 1-310 and the connecting pipe 1-120, to the cylinder 1-100. Hot water can be supplied to the cylinder 1-100, allowing the powder to be brewed and extracted, thus completing the beverage preparation.

[0080] Similarly, beverage making equipment and / or beverage liquid circuit systems generally have a pre-programmed, editable cleaning mode. The purpose of running this cleaning mode is to remove and clean the dirt inside the container 1-100 after one or more beverage making processes.

[0081] In this preparation mode, at least some slag cake and waste residue remain inside the cylinder 1-100. In this cleaning mode, the slag cake and waste residue need to be cleaned and discharged. Therefore, in the cleaning mode, the drive mechanism 1-220 first needs to drive the piston component-210 to move out of the cylinder 1-100 through the opening 1-110, ensuring that the opening 1-110 is partially or fully opened.

[0082] In cleaning mode, specifically, the first connecting pipe 1-310 can be connected to the connecting pipe 1-120. A hot water flow path is established from the hot water boiler 1-410, through the first connecting pipe 1-310 and the connecting pipe 1-120, to the tank 1-100. Hot water can be introduced into the tank 1-100, using the hot water to clean out the dirt inside the tank 1-100 and rinse the inner wall of the tank 1-100 clean.

[0083] In cleaning mode, the second connecting pipe 1-320 can be connected to the connecting pipe 1-120. A steam flow path is established from the steam boiler 1-420, through the second connecting pipe 1-320 and the connecting pipe 1-120, to the cylinder 1-100. Steam can be introduced into the cylinder 1-100, using the steam to clean out the dirt inside the cylinder 1-100 and rinse the inner wall clean.

[0084] It should be noted that in cleaning mode, the first connecting pipe 1-310 and the second connecting pipe 1-320 can be selectively connected to the corresponding connecting pipe 1-120. Alternatively, they can be connected sequentially to the same corresponding connecting pipe 1-120, for example, connecting external hot water first and then external steam, or connecting external steam first and then external hot water.

[0085] During the sequential operation of the preparation mode and the cleaning mode, the orientation of cylinders 1-100 can remain fixed.

[0086] For example, the opening 1-110 remains upward. At this time, the piston element 210 is positioned vertically above the cylinder body 1-100. Driven by the drive mechanism 1-220, the piston element 210 can move up and down reciprocally, thereby achieving the purpose of entering and exiting the cylinder body 1-100 through the opening 1-110. When the connecting pipe 1-120 and the connecting pipeline are connected, external media are introduced into the cylinder body 1-100 to wet and soak the contaminants inside. Furthermore, during continuous connection, the contaminants inside the cylinder body 1-100 can be discharged outward through the opening 1-110.

[0087] At this point, the beverage preparation system may also include a suction line. A suction pump is installed on the suction line. One end of the suction line can be connected to the corresponding pipe 1-120. After connection, the suction pump drives the waste liquid in cylinder 1-100 to be discharged outwards through the suction line.

[0088] Or such as Figures 1 to 4 As shown, during the sequential operation of the preparation mode and the cleaning mode, the orientation of the openings 1-110 can be adjusted. In one specific embodiment, the cylinder 1-100 can be flipped. During this flipping process, the orientation of the openings 1-110 can be adjusted. The flipping of the cylinder 1-100 can be achieved by an additionally configured first power mechanism.

[0089] Specifically, the rotation axis of cylinder 1-100 is generally intersected with the axis of opening 1-110. The axis of opening 1-110 is also basically perpendicular to the plane where opening 1-110 is located. In this way, as cylinder 1-100 rotates around this rotation axis, the orientation of opening 1-110 will change.

[0090] Based on this, when the preparation mode is running, the first power mechanism can drive the cylinder 1-100 to rotate so that the opening 1-110 faces upward (of course, it is not limited to facing upward; in other schemes, it can also face other suitable directions). Similarly, the piston component-210 is vertically and movable above the cylinder 1-100.

[0091] When switching to the cleaning mode, the first power mechanism can drive the cylinder 1-100 to rotate so that the opening 1-110 faces downwards. Specifically, it can be vertically downwards or tilted downwards. Before, during, or after this rotation process, an external medium is introduced. For example, the aforementioned hot water flow path and / or steam flow path is opened. In this way, the hot water and / or steam introduced through the hot water flow path and / or steam flow path can enter the cylinder 1-100, flushing the inner wall of the cylinder 1-100, and the slag cake, waste residue, and waste liquid can all be discharged downwards through the opening 1-110.

[0092] During the sequential operation of the preparation and cleaning modes, the position of cylinder 1-100 can be flexibly adjusted. That is, cylinder 1-100 can be moved. This movement can be a translation along a certain direction, and / or a rotation about an axis extending in a certain direction. Furthermore, depending on actual needs, one or more stopping positions can be set for cylinder 1-100 during its movement stroke.

[0093] For example, the cylinder 1-100 can be positioned at the powder receiving position during its travel. This powder receiving position allows external powder to be fed into the cylinder 1-100 via the opening 1-110. Correspondingly, the beverage preparation system can also include a powder supply unit. The powder supply unit is located at the powder receiving position and can also output powder towards the opening 1-110 of the cylinder 1-100, which is positioned at the powder receiving position.

[0094] This powder supply unit can be directly configured as a powder storage silo. The silo is used to store powder. The outlet of the silo is openable and closable. When open, it discharges the powder, and when closed, it creates a suitable storage environment for the powder within the silo.

[0095] And / or, the powder supply unit may include a grinding mechanism. The grinding mechanism includes a grinding cylinder and a cutter disc movably disposed within the grinding cylinder. When external soybeans are fed into the grinding cylinder, the cutter disc can grind the soybeans through movement to obtain powder of the target particle size. Similarly, the outlet end of the grinding cylinder can be opened and closed, and when opened, the powder is output externally.

[0096] Furthermore, the powder supply unit can also include a bean storage hopper. The inside of the bean storage hopper is used to store the raw beans. The outlet of the bean storage hopper is openable and closable. When opened, the raw beans are discharged outwards. When closed, a suitable storage environment for the raw beans is created inside the bean storage hopper.

[0097] In addition, the beverage preparation system may also include a weighing unit. The weighing unit can be set up independently, or it can be set up together with the powder supply unit. For example, when set up together, the weighing unit can be located between the powder supply unit and the opening 1-110 to weigh the powder entering the cylinder 1-100, ensuring that the quality of the powder entering the cylinder 1-100 meets the target requirements.

[0098] Next, the cylinder 1-100 can be set to stop at the brewing position during its travel stroke. This brewing position and the powder receiving position can be staggered. The piston assembly is correspondingly positioned at this brewing position.

[0099] With the brewing and powder receiving positions set as described above, the tank body 1-100 can perform slag discharge and cleaning at the brewing position and the powder receiving position, respectively. Alternatively, the tank body 1-100 can be set to stop at the cleaning position during its travel stroke. The cleaning, brewing, and powder receiving positions can be staggered. Then, the tank body 1-100 can perform slag discharge and cleaning at the corresponding cleaning position.

[0100] Based on one or more of the above embodiments, it can be understood that, in order to enable the same connecting pipe 1-120 to be adapted and connected to different connecting pipes, in a specific application, the cylinder 1-100, the connecting pipe 1-120, and / or at least one connecting pipe are movable. Thus, during their movement, any connecting pipe can be adapted and connected to the same connecting pipe 1-120.

[0101] It is understood that there are various movement schemes involved above, including but not limited to: only cylinder 1-100 moving relative to the outer shell; only connecting pipe 1-120 moving relative to cylinder 1-100; only connecting pipe moving relative to the outer shell; both cylinder 1-100 and connecting pipe 1-120 being movable; both cylinder 1-100 and connecting pipe being movable; both connecting pipe 1-120 and connecting pipe being movable; and cylinder 1-100, connecting pipe 1-120 and connecting pipe being movable, etc.

[0102] If the configuration is such that the movement of cylinder 1-100 drives any connecting pipe to adapt and connect with the same paired pipe 1-120, then the movement of cylinder 1-100 can specifically manifest as the tilting stroke and / or moving stroke as described above (i.e., the moving stroke that switches between the powder receiving position, the brewing position, and / or the cleaning position). Alternatively, the movement of cylinder 1-100 can also be a separate moving stroke, different from the tilting stroke and / or moving stroke described above, to achieve the purpose of enabling any connecting pipe to adapt and connect with the same paired pipe 1-120.

[0103] Furthermore, in another specific application, the connecting pipes 1-120 and / or at least one connecting pipe can be deformed. During deformation, any connecting pipe can be adapted to connect with the same connecting pipe 1-120.

[0104] Similarly, the deformation schemes mentioned above are varied and may include, but are not limited to: only cylinder 1-100 deforms relative to the outer shell; only connecting pipe 1-120 deforms relative to cylinder 1-100; only connecting pipe deforms relative to the outer shell; both cylinder 1-100 and connecting pipe 1-120 can be deformed; both cylinder 1-100 and connecting pipe can be deformed; both connecting pipe 1-120 and connecting pipe can be deformed; and both cylinder 1-100, connecting pipe 1-120 and connecting pipe can be deformed, etc.

[0105] It should be noted that the deformation can be a flexible deformation under the action of one external force, and then a return to its original position under the action of another external force. Alternatively, the deformation can be an elastic deformation under the action of one external force, and then an elastic return to its original position after the external force is removed. Furthermore, the deformation can be a deformation of elongation and shortening along one direction, a deformation of expansion and contraction along one direction, or a bending deformation in one direction, etc.

[0106] In addition, the beverage preparation system may also include a second power mechanism. The second power mechanism is connected to the movable or deformable cylinder 1-100, the connecting pipe 1-120, and / or at least one connecting pipe as described above.

[0107] Based on one or more of the above embodiments, it can be understood that there are no restrictions on the connection method between the connecting pipe and the opposing pipe 1-120.

[0108] In one specific embodiment, the connecting pipe and the docking pipe 1-120 can be sealed and abutted by the two pipe end faces.

[0109] Alternatively, in another specific embodiment, one of the connecting pipes and the mating pipes 1-120 is provided with a protruding insertion portion, and the other with a recessed insertion portion. The protruding and recessed insertion portions are then inserted and fixed together. This insertion between the protruding and recessed insertion portions helps increase the connection area, thereby enhancing the connection strength. It also helps increase the tightness of the connection. Furthermore, compared to surface-to-surface contact, the protruding insertion portion can be guided into the recessed insertion portion during the insertion process, thus improving the ease of connection operation for the connecting pipes and mating pipes 1-120.

[0110] Furthermore, the pipes 1-120 are adapted for connection to different connecting pipes. In a specific application, the connection requirements for each connecting pipe can be the same. In this case, there is no difference in the connection between the same pair of pipes 1-120 and any other connecting pipe. Therefore, the structure of each connecting pipe can be uniformly set.

[0111] Or such as Figures 6 to 7 As shown, in another specific application, at least two connecting pipes have different connection requirements with the same pair of pipes 1-120.

[0112] It is understood that the above connection requirements may include, but are not limited to, the connection strength, connection sealing, heat resistance of the connection parts, and thermal insulation of the connection parts between the connecting pipes and the connecting pipes 1-120.

[0113] For example, the connection between the connecting pipe for external hot water circulation and the connecting pipe 1-120 needs to have sufficient sealing, heat resistance, and insulation. The connection between the connecting pipe for external steam circulation and the connecting pipe 1-120 needs to have sufficient connection strength, sealing, and heat resistance.

[0114] Correspondingly, in a specific solution, at least two connecting pipes form different connection parts to suit their own connection requirements. For example, when the connecting pipes are the first connecting pipe 1-310 and the second connecting pipe 1-320, the connection part of the first connecting pipe 1-310 is the first connection part 1-311, and the connection part of the second connecting pipe 1-320 is the second connection part 1-321.

[0115] Each connection part is adapted to connect to the same pair of pipes 1-120. That is, by adjusting the structure of different connection pipes, different connection effects can be achieved when connecting to the same pair of pipes 1-120, ultimately meeting their own connection requirements.

[0116] For example, the connections of each connecting pipe may differ in size, shape and / or material, so that each connection may form a different connection strength with the same pair of pipes 1-120.

[0117] Taking a connecting pipe with a protruding insertion part and a connecting pipe 1-120 with a recessed insertion part as an example: Specifically, different connecting parts can be set to form insertion protrusions with different outer diameters, and even the insertion protrusion with the smallest outer diameter can achieve a stable insertion with the insertion recess. Then, as the outer diameter is appropriately increased, the insertion strength between the insertion protrusion and the insertion recess can gradually increase, and the insertion sealing performance can gradually increase.

[0118] Alternatively, different connecting parts can be designed as interlocking protrusions made of different materials. Different materials result in different heat resistance, wear resistance, structural strength, etc.

[0119] And / or correspondingly, in a specific embodiment, the connecting pipes 1-120 are adapted to form at least two mating parts for different connection requirements. Each mating part is adapted to connect to each connecting pipe in a one-to-one manner. For example, when the connecting pipes are respectively the first connecting pipe 1-310 and the second connecting pipe 1-320, each mating part includes a first mating part 1-121 and a second mating part 1-122.

[0120] In other words, by adjusting the structure of different mating parts of the same pair of pipes 1-120, different connection effects can be achieved when connecting with different connecting pipes, ultimately meeting the connection requirements corresponding to the connecting pipe.

[0121] For example, the connecting parts of pipes 1-120 are different in size, shape and / or material, so that each connecting part can be adapted to form different connection strengths after being connected to different connecting pipes.

[0122] It should be noted that there are no restrictions on how the same pipe network 1-120 can form at least two connecting parts. For example, at least two pipe segments can be sequentially installed along the length of the pipe network 1-120. Each of these at least two pipe segments corresponds to one of the connecting parts.

[0123] The various mating parts can differ in size, shape, and / or material. For example, assuming the connecting pipe has a protruding insertion part and the mating pipe 1-120 has a recessed insertion part: Specifically, different mating parts can be set to form insertion recesses with different inner diameters, and even the insertion recess with the largest inner diameter can achieve a stable insertion with the insertion protrusion. Then, when the inner diameter is appropriately reduced, the insertion strength between the insertion protrusion and the insertion recess can gradually increase, and the insertion sealing performance can gradually increase.

[0124] When the joint is formed by pipe segments, the inner diameter of the insertion recess can be gradually reduced along its depth direction (i.e., the insertion direction). Alternatively, the inner diameter can be reduced in a multi-step manner along its depth direction.

[0125] Alternatively, different mating parts can be designed as insertion recesses made of different materials. Different materials result in different heat resistance, wear resistance, structural strength, etc.

[0126] And / or correspondingly, in a specific embodiment, the beverage preparation system also includes auxiliary devices. The auxiliary devices are at least located at the connection point between a connecting pipe and a connecting pipe 1-120 to adjust the connection point to meet the required connection. That is, the connecting pipe and the connecting pipe 1-120 may not require the structural differentiation adjustments described above (although adjustments are possible), and can then be achieved using external auxiliary devices to match different connection requirements between different connecting pipes and the same connecting pipe 1-120.

[0127] The auxiliary devices, connecting pipes, and connecting pipes 1-120 are installed separately, but this does not constitute a limitation on the connection relationship between the auxiliary devices and connecting pipes, or between the auxiliary devices and connecting pipes 1-120. For example, depending on actual needs, the auxiliary devices can remain connected to the connecting pipes. Or, the auxiliary devices can remain connected to the connecting pipes 1-120. Alternatively, the auxiliary devices can be installed separately from the connecting pipes and connecting pipes 1-120.

[0128] The specific form of the auxiliary device is not limited: In one specific embodiment, the auxiliary device may include a sealing structure 1-500. The sealing structure 1-500 may be, for example, a sealing ring, a sealing protrusion, or an outer sleeve. For connection parts with high sealing requirements, a sealing structure 1-500 with stronger sealing strength can be selected. Conversely, for connection parts with lower sealing requirements, a sealing structure 1-500 with weaker sealing strength can be selected, or no sealing structure 1-500 may be chosen.

[0129] In one specific design, the auxiliary device may include an anti-slip structure. This anti-slip structure can be, for example, anti-slip protrusions or a roughened surface. For connection parts requiring high connection strength, an anti-slip structure with greater roughness and stronger anti-slip properties can be selected. Conversely, for connection parts requiring lower connection strength, an anti-slip structure with less roughness and weaker anti-slip properties can be selected.

[0130] In one specific embodiment, the auxiliary device may include a locking structure. The locking structure may be, for example, a snap-fit ​​structure located at the connection point, or a stop protrusion located behind the connection point in the insertion direction. When a locking structure is provided, it can effectively prevent the connected pipes and the connecting pipes 1-120 from separating or detaching due to external forces, thus helping to enhance the connection strength of the connection points.

[0131] In one specific embodiment, the auxiliary device may include a force-applying mechanism. This mechanism is driven to connect the connecting pipe and / or the parallel pipe 1-120 to create the required connection strength between them and to prevent separation. In other words, the force-applying mechanism can apply a thrust to the connection point after the connecting pipe and parallel pipe 1-120 are connected. By adjusting the magnitude of this thrust, different connection strengths can be achieved at the connection point, and the connecting pipe will not separate from the parallel pipe 1-120 under the action of the force-applying mechanism. This force-applying mechanism is more suitable for situations with high external medium pressure, such as when it is positioned between the second connecting pipe 1-320 and the parallel pipe 1-120 as described above.

[0132] Furthermore, when, as described above, the cylinder 1-100, connecting pipe, and / or coupling pipe 1-120 are moved via a second power mechanism to achieve a mating connection between the connecting pipe and the coupling pipe 1-120, the force-applying mechanism can also be directly constituted by this second power mechanism. In this case, the force-applying mechanism first drives the connecting pipe and the coupling pipe 1-120 to move and connect. Then, it pushes the connecting pipe and the coupling pipe 1-120 to form the required connection strength. Finally, it effectively prevents the connecting pipe and the coupling pipe 1-120 from separating.

[0133] The force-applying mechanism at this time can be, for example, a motor or a cylinder. It can also be a combination of a motor or cylinder and a transmission component.

[0134] When the force-applying mechanism is provided as described above, the auxiliary device may further include the sealing structure 1-500 as described above. The sealing structure 1-500, driven by the force-applying mechanism, can be selectively disposed between any connecting pipe and connecting pipe 1-120. And / or, the sealing structure 1-500 can be maintained between the connecting pipe and connecting pipe 1-120, but can subsequently form different sealing strengths under the action of the force-applying mechanism. For example, the sealing structure 1-500 is an elastic sealing ring. The elastic sealing ring deforms to different degrees under different external forces from the force-applying mechanism, thereby forming different sealing effects.

[0135] For example Figure 7As shown, when the first connecting pipe 1-310 is connected to the connecting pipe 1-120, the force-applying mechanism applies a first external force F1 to the connection point. When the second connecting pipe 1-320 is connected to the connecting pipe 1-120, the force-applying mechanism applies a second external force F2 to the connection point. If the first connecting pipe 1-310 is used to connect to external hot water and the second connecting pipe 1-320 is used to connect to external steam, then the second external force F2 can be greater than the first external force F1 to ensure that the connection strength between the second connecting pipe 1-320 and the connecting pipe 1-120 is sufficient to withstand the high temperature and high pressure impact during steam flow.

[0136] Second application example: The currently provided brewing assembly features a single-opening, single-piston configuration, which significantly reduces the space and structural footprint of a single piston component. However, this brewing assembly also makes the entire brewing tank difficult to clean.

[0137] To address this issue, the present invention also proposes a brewing and dregs removal system and beverage preparation equipment, aiming to solve the problem of difficulty in dregs removal in brewing tanks with single openings and single pistons.

[0138] Please see Figures 8 to 15 This invention provides a brewing and dregs removal system and its applicable beverage preparation equipment.

[0139] It is understandable that this beverage making equipment can be used to brew any suitable powder or other solid material to make beverages.

[0140] Beverage-making equipment generally also includes a housing. The brewing and rinsing system is at least partially built into the housing. For ease of understanding, the following embodiments are illustrated using an example where the beverage-making equipment has two intersecting horizontal, vertical, and longitudinal axes. In practical applications, the horizontal, vertical, and longitudinal axes can be perpendicular or nearly perpendicular to each other. Furthermore, the vertical axis can specifically correspond to the direction of gravity, while the horizontal and longitudinal axes roughly correspond to any two horizontal directions on the horizontal plane.

[0141] Therefore, the brewing and cleaning system includes at least a brewing unit. Specifically, the brewing unit may include a brewing cylinder 2-100, a piston assembly, and a cleaning component 2-300.

[0142] The brewing tank 2-100 has an open end 2-110 located at one end of its central axis.

[0143] The piston assembly includes a piston element 2-210 and a drive mechanism 2-220. The drive mechanism 2-220 and the piston element 2-210 are driven together so that, driven by the drive mechanism 2-220, the piston element 2-210 can freely enter and exit the brewing cylinder 2-100 through the opening 2-110.

[0144] The cleaning component 2-300 is located outside the brewing tank 2-100. The cleaning component 2-300 can act inside the brewing tank 2-100 after the brewing cleaning system switches to the preset cleaning mode, so as to discharge the dirt inside the brewing tank 2-100.

[0145] In the technical solution provided by this invention, the brewing cylinder 2-100 has only one opening 2-110, and is equipped with a single piston component 2-210. This helps to avoid the complexity and increased weight of a double-opening, double-piston structure, resulting in a more compact overall structure and less space occupation. This contributes to the miniaturization of the entire brewing unit, allowing it to be widely used in various models. Furthermore, to a certain extent, the single-opening 2-110 and single-piston component 2-210 design simplifies the hydraulic system of the entire machine, enabling rapid response and high-efficiency conversion, thereby significantly improving the efficiency of beverage preparation.

[0146] The brewing and cleaning system has preset brewing and cleaning modes. In brewing mode, the cleaning component 2-300 will not interfere with the normal operation of the brewing tank 2-100 and the piston assembly. When switched to cleaning mode, the cleaning component 2-300 will operate within the brewing tank 2-100 to clean and discharge any residual cake residue, solid residue, and waste liquid after brewing, ensuring the quality of subsequent brewing in the brewing tank 2-100.

[0147] First, it should be noted that the central axis of the brewing cylinder 2-100 refers to the central axis of the brewing cylinder 2-100 along any dimensional direction. For example, when the brewing cylinder 2-100 extends vertically in a certain state, its central axis can also extend vertically. In this case, the vertical end of the brewing cylinder 2-100 has an opening 2-110. Therefore, conversely, the central axis of the brewing cylinder 2-100 intersects the plane of the opening 2-110, which is essentially equivalent to the central axis of the opening 2-110.

[0148] In this application, as Figure 10 As shown, beverage making equipment and / or brewing and rinsing systems generally have a brewing mode that can be programmed via a preset program. The purpose of operating this brewing mode is to prepare a beverage from, for example, powder. Therefore, in the brewing mode, the drive mechanism 2-220 drives the piston 2-210 through the opening 2-110 into the brewing cylinder 2-100, and moves it to the target position within the brewing cylinder 2-100 to press the powder already received in the brewing cylinder 2-100 into a cake of the target thickness.

[0149] Then, the brewing and dregs removal system is generally equipped with a hot water pipeline. The hot water pipeline can be connected to an external hot water source and the brewing tank 2-100, so that external hot water can be introduced into the brewing tank 2-100 to brew and extract the powder cake in the brewing tank 2-100, and complete the beverage preparation.

[0150] Similarly, as Figures 11 to 12 ,or Figures 14 to 15 As shown, beverage making equipment and / or brewing and cleaning systems are generally editable via preset programs and can also have a cleaning mode. The purpose of running this cleaning mode is to remove and clean the dirt in the brewing tank 2-100 after one or more beverage preparations.

[0151] After brewing, residue, waste residue, and waste liquid may remain in brewing tank 2-100. In this cleaning mode, the residue, waste residue, and waste liquid need to be removed to restore the brewing tank 2-100 to a clean state as much as possible.

[0152] Therefore, in the slag removal mode, the drive mechanism 2-220 first needs to drive the piston 2-210 to move out of the brewing tank 2-100 through the opening 2-110, ensuring that the opening 2-110 is partially or fully opened. The piston 2-210 moved out of the brewing tank 2-100 can be arranged sequentially and alternately with the opening 2-110 along the central axis of the brewing tank 2-100, that is, still facing the opening 2-110. Alternatively, the piston 2-210 moved out of the brewing tank 2-100 can be radially offset from the opening 2-110 along the central axis of the brewing tank 2-100, that is, partially facing or completely offset from the opening 2-110.

[0153] It should be noted that the position of the brewing tank 2-100 can remain fixed during the sequential operation of the brewing mode and the slag removal mode.

[0154] Specifically, for example, the opening 2-110 can remain upward. That is, in brewing mode, the piston 2-210 is positioned vertically above the brewing tank 2-100. Driven by the drive mechanism 2-220, the piston 2-210 can move up and down reciprocally, thereby achieving the purpose of entering and exiting the brewing tank 2-100 through the opening 2-110. When switching to the slag removal mode, the orientation of the opening 2-110 remains unchanged, and the slag removal component 2-300 acts within the brewing tank 2-100 based on this state.

[0155] Alternatively, during the sequential operation of the brewing mode and the slag removal mode, the orientation of the opening 2-110 can be adjustable. In one specific embodiment, the brewing tank 2-100 can be flipped. During this flipping process, the orientation of the opening 2-110 can be adjusted. The flipping of the brewing tank 2-100 can be achieved by an additionally configured first power mechanism.

[0156] Specifically, the rotation axis of the brewing cylinder 2-100 is generally intersected with the central axis of the brewing cylinder 2-100, that is, basically perpendicular to the plane where the opening 2-110 is located. In this way, as the brewing cylinder 2-100 rotates around this rotation axis, the orientation of the opening 2-110 will change.

[0157] Based on this, when the brewing mode is running, the first power mechanism can drive the brewing cylinder 2-100 to rotate so that the opening 2-110 faces upward (of course, it is not limited to facing upward; in other solutions, it can also face other suitable directions). Similarly, the piston 2-210 is vertically and movable above the brewing cylinder 2-100.

[0158] When switching to the slag removal mode, the first power mechanism can drive the brewing tank 2-100 to flip so that the opening 2-110 faces downwards. Specifically, it can be vertically downwards or tilted downwards. Before, simultaneously with, or after flipping so that the opening 2-110 faces downwards, the slag removal component 2-300 can act within the brewing tank 2-100.

[0159] During the sequential operation of the brewing mode and the slag removal mode, the position of the brewing cylinder 2-100 can be flexibly adjusted. That is, the brewing cylinder 2-100 can be moved. This movement can be a translation along a certain direction, and / or the movement can also be a rotation around a central axis extending in a certain direction. Furthermore, depending on actual needs, one or more stop positions of the brewing cylinder 2-100 can be set along its movement stroke.

[0160] For example Figures 8 to 9 ,or Figure 13 As shown, the brewing tank 2-100 can be positioned at the powder receiving position during its travel stroke. This powder receiving position allows external powder to be fed into the brewing tank 2-100 via the opening 2-110. Correspondingly, the brewing and slag removal system can also include a powder supply unit. The powder supply unit is located at the powder receiving position and can also output powder towards the opening 2-110 of the brewing tank 2-100, which is positioned at the powder receiving position.

[0161] This powder supply unit can be directly configured as a powder storage silo. The silo is used to store powder. The outlet of the silo is openable and closable. When open, it discharges the powder, and when closed, it creates a suitable storage environment for the powder within the silo.

[0162] And / or, the powder supply unit may include a grinding mechanism. The grinding mechanism includes a grinding cylinder and a cutter disc movably disposed within the grinding cylinder. When external soybeans are fed into the grinding cylinder, the cutter disc can grind the soybeans through movement to obtain powder of the target particle size. Similarly, the outlet end of the grinding cylinder can be opened and closed, and when opened, the powder is output externally.

[0163] Furthermore, the powder supply unit can also include a bean storage hopper. The inside of the bean storage hopper is used to store the raw beans. The outlet of the bean storage hopper is openable and closable. When opened, the raw beans are discharged outwards. When closed, a suitable storage environment for the raw beans is created inside the bean storage hopper.

[0164] In addition, the brewing and slag removal system may also include a weighing unit. The weighing unit can be set up independently, or it can be set up together with the powder supply unit. For example, when set up together, the weighing unit can be positioned between the powder supply unit and the opening 2-110 to weigh the powder entering the brewing tank 2-100, ensuring that the quality of the powder entering the brewing tank 2-100 meets the target requirements.

[0165] Next, the brewing cylinder 2-100 can be configured to stop at the brewing position during its travel stroke. This brewing position and the powder receiving position can be staggered. The piston assembly is correspondingly positioned at this brewing position.

[0166] With the brewing position and powder receiving position set as described above, the brewing tank 2-100 can perform slag removal and cleaning at the brewing position and the powder receiving position, respectively. Alternatively, the brewing tank 2-100 can be set to stop at the slag removal position during its travel. The slag removal position, brewing position, and powder receiving position can be staggered. Then, the brewing tank 2-100 can perform slag removal and cleaning at the corresponding slag removal position.

[0167] Based on the above, after switching to the slag removal mode, the slag removal component 2-300 acts inside the brewing tank 2-100, which can discharge the dirt inside the brewing tank 2-100. During this process, the dirt inside the brewing tank 2-100 will at least fall off from the tank wall of the brewing tank 2-100, and can eventually be discharged out through the opening 2-110.

[0168] Alternatively, if impurities in the brewing tank 2-100 detach from the inner wall of the brewing tank 2-100, they may fall into the brewing tank 2-100. In this case, the cleaning component 2-300 has a pre-installed guiding structure. This guiding structure can be specifically manifested as a channel structure, as described in the following embodiments. This channel can be switched to create negative pressure. For example, a suction pump or similar mechanism can be used to create negative pressure. Under this negative pressure, the impurities in the brewing tank 2-100 will be sucked out of the brewing tank 2-100 through the channel.

[0169] Of course, this guiding structure can also be specifically manifested as a through-channel structure. The through-channel structure can, for example, extend at an angle relative to the direction of gravity, or extend vertically directly along the direction of gravity, using gravity to discharge the dirt in the brewing tank 2-100 to the outside.

[0170] As can be seen from the above, at least in the slag removal mode, the slag removal component 2-300 operates within the brewing tank 2-100. There are several ways to achieve this.

[0171] For example, in one setting, at least after switching to the slag removal mode, the slag removal component 2-300 can directly act on the brewing tank 2-100 via the opening 2-110.

[0172] Alternatively, the brewing tank 2-100 may have other opening structures besides the open end 2-110. These opening structures can be opened when needed and closed when not needed, ensuring the airtightness of the brewing tank 2-100 except for the open end 2-110. Thus, in another configuration, at least after switching to the cleaning mode, the cleaning component 2-300 can directly act within the brewing tank 2-100 via these opening structures.

[0173] The specific form of this opening structure can be varied. It can be a through hole directly formed in the brewing tank 2-100. Alternatively, in one specific design, a guide member 2-120 is provided on the outer wall of the brewing tank 2-100. The guide member 2-120 allows communication between the inside and outside of the brewing tank 2-100. The hollow structure inside the guide member 2-120 constitutes the structure of this opening.

[0174] As mentioned above, the specific forms in which the slag removal component 2-300 acts within the brewing tank 2-100 via the open opening 2-110 / open structure / conductor 2-120 are varied: In one configuration, when switching to the slag removal mode, the slag removal component 2-300 can remain outside the brewing tank 2-100. However, the slag removal component 2-300 can remove slag from the inside of the brewing tank 2-100 remotely using the open end 2-110 / open structure / conductor 2-120.

[0175] Specifically, for example, the slag-cleaning component 2-300 can be hollow and form a channel. One end of the slag-cleaning component 2-300 can be connected to an external medium source, ensuring that the external medium output from the external medium source can enter the channel. An outlet is provided at the other end of the slag-cleaning component 2-300 and / or on the side wall near its other end. The external medium flowing within the channel can be discharged outwards through this outlet.

[0176] Then, when switching to the slag removal mode, the outlet of the slag removal component 2-300 can be set towards the port of the open 2-110 / open structure / conductor 2-120 to ensure that the external medium discharged outward through the outlet can enter the brewing tank 2-100 through the port of the open 2-110 / open structure / conductor 2-120.

[0177] Taking the configuration of the connecting component 2-120 as an example, when switching to the slag removal mode, the slag removal component 2-300 can be connected to the connecting component 2-120. This allows the channel of the slag removal component 2-300 to connect with the hollow structure of the connecting component 2-120. In this way, the external medium in the channel can be introduced into the brewing tank 2-100 through the connecting component 2-120.

[0178] It should be noted that the cleaning component 2-300 and the conductor 2-120 can remain connected at all times. Under this configuration, if there is mutual movement between the cleaning component 2-300 and the conductor 2-120, adaptation can be achieved either through a pre-defined, appropriate follow-up sliding (while maintaining connection) between the cleaning component 2-300 and the conductor 2-120, or through the follow-up deformation of, for example, the deformable section connecting the cleaning component 2-300 and the conductor 2-120.

[0179] The deformable segment can be made of a flexible structure. That is, the deformable segment can deform under the action of an external force and return to its original position under another external force. Alternatively, the deformable segment can also be made of an elastic material. That is, the deformable segment can deform under the action of an external force and return to its original position after the external force is removed.

[0180] Of course, the slag-cleaning component 2-300 and the connecting component 2-120 can also be connected in a disengaging manner. That is, when needed, such as after switching to slag-cleaning mode, the slag-cleaning component 2-300 and the connecting component 2-120 are connected, switching to the first state. And when not needed, the slag-cleaning component 2-300 and the connecting component 2-120 are separated, switching to the second state.

[0181] Or in another setting, such as Figures 11 to 12 ,or Figures 14 to 15 As shown, when switching to the cleaning mode, the cleaning component 2-300 can extend at least partially into the brewing tank 2-100 via the opening 2-110 / open structure / conductor 2-120. This ensures that at least a portion of the cleaning component 2-300 is located within the brewing tank 2-100, allowing for the removal of impurities from the brewing tank 2-100 through this extended portion. In this configuration, the extended portion of the cleaning component 2-300 strengthens the connection between the cleaning component 2-300 and the brewing tank 2-100, shortening the interaction distance between them and thus contributing to a certain degree of enhanced relative interaction strength.

[0182] At this time, the slag removal component 2-300 and the brewing tank 2-100 / conductor 2-120 are generally connected in a disengaging manner. That is, they can switch to the first state after connection and switch to the second state after separation.

[0183] To achieve the above objectives, in a further embodiment, the brewing tank 2-100 and / or the slag-cleaning component 2-300 are movable. During their movement, the slag-cleaning component 2-300 and the connecting component 2-120 are in a first connected state and a second separated state. At least after the brewing and slag-cleaning system switches to the slag-cleaning mode, the slag-cleaning component 2-300 and the connecting component 2-120 switch to the first state.

[0184] The movement of the brewing tank 2-100 can be achieved by flipping it as described above. For example... Figures 11 to 12 ,or Figures 14 to 15 As shown, after the brewing and slag removal system switches to the slag removal mode, the brewing cylinder 2-100 flips so that the open end 2-110 faces downwards. Before, simultaneously, or after this, the slag removal component 2-300 and the brewing cylinder 2-100 / conductor 2-120 switch to the first state.

[0185] And / or, the movement of the brewing tank 2-100 can also be a translation as described above. For example, after the brewing and cleaning system switches to the cleaning mode and the brewing tank 2-100 is translated to the cleaning position, the cleaning component 2-300 and the brewing tank 2-100 / conductor 2-120 switch to the first state.

[0186] Of course, the cleaning component 2-300 can also move. That is, after the brewing and cleaning system switches to the cleaning mode, the cleaning component 2-300 moves toward the brewing tank 2-100 / conductor 2-120, and finally stops after moving to the first state.

[0187] As mentioned above, the slag removal component 2-300 may be provided with a channel. Then, after switching to the slag removal mode, the external medium discharged from the external medium source is introduced into the brewing tank 2-100 through this channel.

[0188] At this time, the external medium needs to be set in a direction that facilitates cleaning within the brewing tank 2-100. For example, it can be, but is not limited to, high-temperature hot water, high-temperature and high-pressure steam, high-pressure gas, high-pressure hot water, etc.

[0189] Correspondingly, there are no restrictions on the specific form of the external medium source. For example, it can be, but is not limited to: The brewing and slag removal system may also include a hot water module. This hot water module may include a hot water boiler and a heater. After sufficient liquid is supplied to the hot water boiler, the heater heats the liquid to the desired temperature, forming high-temperature hot water. The high-temperature hot water is stored in the hot water boiler. The hot water boiler and the slag removal unit 2-300 can be connected on and off. When connected, the high-temperature hot water is supplied to the brewing tank 2-100.

[0190] The brewing and slag removal system may also include a steam module. This steam module may include a steam boiler and a heater. After sufficient liquid is introduced into the steam boiler, the heater heats the liquid to the desired temperature and pressure, forming high-temperature, high-pressure steam. This high-temperature, high-pressure steam can be stored in the steam boiler. The steam boiler and the slag removal component 2-300 are connectable and disconnectable. When connected, the high-temperature, high-pressure steam is introduced into the brewing tank 2-100.

[0191] The brewing and slag removal system may also include an air storage module. The air storage module includes an air tank and a pressurizer. The air tank is responsively connected to the slag removal component 2-300, and when connected, the pressurizer is used to adjust the air pressure inside the brewing cylinder 2-100 to a preset air pressure threshold, thereby using high-pressure gas to rinse the inside of the brewing cylinder 2-100.

[0192] The brewing and sludge removal system may also include a water storage module. The water storage module includes a water storage container and a pressure booster. The water storage container is detachably connected to the sludge removal component 2-300. When connected, the pressure booster is used to adjust the air pressure of the water entering the brewing tank 2-100 to reach a preset air pressure threshold, thereby using high-pressure water to rinse the brewing tank 2-100.

[0193] Furthermore, the cleaning component 2-300 may also be provided with an interference part 2-310. After the cleaning component 2-300 extends into the brewing tank 2-100, it at least causes the interference part 2-310 to extend into the brewing tank 2-100. Interference occurs between the interference part 2-310 and the inner wall of the brewing tank 2-100. Through this interference process, the interference part 2-310 can scrape off any solid residue remaining on the inner wall of the brewing tank 2-100.

[0194] The specific form of the interference part 2-310 is not limited; it can be, but is not limited to, a brush body, cloth, sponge, flexible material block, elastic material block, rigid material block, etc. The interference part 2-310 and the slag-cleaning component 2-300 can be integrally formed. Alternatively, the interference part 2-310 and the slag-cleaning component 2-300 can be separately formed, and then connected in a detachable or non-detachable manner.

[0195] When interference occurs between the interference section 2-310 and the inner wall of the brewing tank 2-100, meaning that they can directly or indirectly form an interference force, this interference force can be used to scrape off the dirt remaining on the inner wall of the brewing tank 2-100 through reasonable structural and operational design.

[0196] There are several ways to generate interference between the inner wall of the interference section 2-310 and the brewing tank 2-100: For example, when the cleaning component 2-300 extends into the brewing tank 2-100 via the opening 2-110 / open structure / conductor 2-120, a relative movement inevitably occurs between the cleaning component 2-300 and the inner wall of the brewing tank 2-100. This relative movement can cause interference between the interference portion 2-310 and the inner wall of the brewing tank 2-100.

[0197] Alternatively, for example, after the cleaning component 2-300 extends into the brewing tank 2-100 via the opening 2-110 / open structure / conductor 2-120, at least one of the brewing tank 2-100 and the interference part 2-310 is movably arranged relative to the other. This allows interference to occur between the brewing tank 2-100 and the interference part 2-310 during its movement. That is, after the cleaning component 2-300 has at least driven the interference part 2-310 into the brewing tank 2-100, an additional power mechanism can drive the brewing tank 2-100 and / or the interference part 2-310 to move, thereby forming a relative movement stroke between the brewing tank 2-100 and the interference part 2-310. This relative movement stroke achieves the purpose of generating interference between the brewing tank 2-100 and the interference part 2-310.

[0198] The specific design of the relative movement stroke between the brewing tank 2-100 and the interference section 2-310 is not limited. For example, Figure 11 or Figure 14 As shown, the brewing cylinder 2-100 and / or the interference part 2-310 can translate along one or more dimensional directions of the brewing cylinder 2-100. Specifically, they can translate along the central axis, radially along the central axis, or circumferentially along the central axis of the brewing cylinder 2-100, to ensure that the interference part 2-310 can travel along the inner wall of the brewing cylinder 2-100 as much as possible, and its travel area should cover the entire inner wall of the brewing cylinder 2-100 as much as possible.

[0199] Or for example Figure 11 or Figure 14As shown, at least one of the brewing cylinder 2-100 and the interference part 2-310 is rotatably arranged relative to the other about the central axis of the brewing cylinder 2-100, so that interference is generated between the brewing cylinder 2-100 and the interference part 2-310 during its rotation. That is, the brewing cylinder 2-100 and / or the interference part 2-310 can rotate along the central axis of the brewing cylinder 2-100. Under this rotation, it is equivalent to driving the interference part 2-310 to travel a full circumference along the central axis of the brewing cylinder 2-100. Especially when the interference part 2-310 extends sufficiently into the brewing cylinder 2-100, for example, when the insertion depth of the interference part 2-310 along the axial direction of the brewing cylinder 2-100 is substantially equal to the depth of the brewing cylinder 2-100, the above-mentioned rotation can achieve full-area cleaning of the inner wall of the brewing cylinder 2-100 by the interference part 2-310.

[0200] It should be noted that the two methods mentioned above can coexist, that is, as follows: Figure 12 or Figure 15 As shown, the cleaning component 2-300 is provided with a channel as described above, which can be connected to an external medium. Furthermore, the cleaning component 2-300 is also provided with an interference portion 2-310 as described above. Therefore, the cleaning component 2-300 can both scrape off residual dirt from the inner wall of the brewing tank 2-100 through the interference portion 2-310 and flush the inner wall of the brewing tank 2-100 with the help of an external medium, thus further enhancing the overall cleaning strength and optimizing the overall cleaning effect.

[0201] Furthermore, since the guide component 2-120 can be activated at least after switching to the slag-cleaning mode, its structural configuration can be adjusted to facilitate the operation of the slag-cleaning mode. For example, regarding the orientation of the guide component 2-120. Let the brewing tank 2-100 be defined as having one end with an opening 2-110, the tank bottom along the central axis of the brewing tank 2-100 away from the opening 2-110, and the tank side connecting the opening 2-110 and the tank bottom.

[0202] Specifically, the guide component 2-120 can be directly installed at the end of the brewing tank 2-100 facing away from the opening 2-110 along its central axis. That is, it is installed at the bottom of the tank.

[0203] At this point, if the slag removal component 2-300 is equipped with a channel, external media can be introduced from the bottom of the tank. The external media can gradually fill the entire space inside the brewing tank 2-100 from the bottom. Furthermore, the flow force of the external media can be used to lift up the solid slag deposited at the bottom of the tank.

[0204] If the cleaning component 2-300 is equipped with an interference part 2-310, mutual interference can also be generated from the bottom of the tank, which will help to clean the slag inside the brewing tank 2-100 more thoroughly.

[0205] Of course, the guide component 2-120 can also be located on the side wall of the brewing tank 2-100, i.e., on the side of the tank. It should be spaced apart from the opening 2-110 along the central axis of the brewing tank 2-100. Specifically, the guide component 2-120 can be located as far away from the opening 2-110 as possible on the side of the tank, which also helps to achieve the goal of cleaning slag starting from the bottom of the tank. When the guide component 2-120 is located on the side of the tank, the slag cleaning component 2-300 connected to it is generally located beside the brewing tank 2-100. This minimizes the overall space occupied along the central axis of the brewing tank 2-100, such as reducing the vertical space occupied, resulting in a smaller overall vertical dimension of the machine.
