Description

A high-efficiency driving mechanism, beverage equipment and control method thereof Technical Field

[0001] The present invention relates to the technical field of beverage preparation, and in particular to a high-efficiency driving mechanism, beverage equipment and a control method thereof. Background Art

[0002] To ensure the taste and quality of the extracted coffee, the coffee beans are ground just before the coffee is extracted to preserve the flavor of the coffee beans. A fully automatic coffee machine is a machine that can grind the coffee beans into powder with a single click, all the way to brewing the coffee. In the existing coffee-making process, the coffee beans are first ground into powder by a grinding device, which is then discharged into a brewing container at a powder receiving position. The brewing container is then moved to the brewing position, where a pressing mechanism presses the coffee powder in the brewing container into a powder cake. Finally, the pressed powder cake is brewed and extracted to make coffee. Grinding the coffee beans into powder is the longest step in the entire coffee extraction process.

[0003] In the prior art, when the brewing container moves to the powder receiving position, the grinding device starts and grinds the coffee powder; then when the brewing container moves out of the powder receiving position, the grinding device stops grinding the coffee powder; when the brewing container moves to the brewing position and returns to the powder receiving position after completing the first cup of drink, the grinding device restarts and grinds the coffee powder... and so on, which increases the waiting time of the brewing container at the powder receiving position, thereby reducing the coffee preparation efficiency.

[0004] Existing beverage preparation equipment, such as coffee machines, generally integrates functions such as coffee bean grinding, coffee powder transfer, extraction and brewing, and residue cleaning. Specifically, the coffee machine is equipped with a brewing component, including a brewing container. The ground coffee powder is poured into the brewing container, and the brewing container is used to pressurize the coffee powder and perform high-temperature extraction. After the coffee machine has completed the preparation of each cup of coffee beverage, the powder cake in the brewing container needs to be discharged. Typically, the powder cake in the brewing container is pushed out of the brewing container and the coffee grounds are cleared from the brewing container using a scraper or other structure. After high-temperature extraction, the coffee grounds have a certain degree of adhesion and stickiness. After long-term use, coffee grounds are easily left on the scraper. During the scraping process, the grounds may also break and adhere to the scraper. When the brewing container is brewed again, the coffee grounds are easily brought into the brewing container, causing contamination of the brewing container, thereby affecting the extraction quality of the beverage and causing the taste and quality of the beverage to deteriorate.

[0005] Existing beverage preparation equipment, such as coffee machines, generally integrates functions such as grinding coffee beans, transferring coffee powder, extracting and brewing, and cleaning residues. Among them, the coffee machine is provided with a brewing device, including a brewing container. The ground coffee powder is poured into the brewing container, and the brewing container is used to pressurize the coffee powder and extract it at high temperature. After the coffee machine completes the preparation of each cup of coffee beverage, the powder cake residue in the brewing container needs to be discharged. Usually, the powder cake residue in the brewing container is pushed upward out of the brewing container, and the coffee grounds are scraped out of the brewing container by a scraper or other structure. Since the existing scraper is usually set with a rigid structure, the scraper is relatively hard and will not completely fit the surface to be cleaned of the brewing container. As a result, the scraping will contaminate the surface of the brewing container and the top residue part while scraping, resulting in poor scraping effect.

[0006] A coffee machine is a machine that grinds coffee beans into powder and brews coffee. In the existing coffee-making process, the coffee beans are first ground by a grinding device, which then discharges the grounds into a brewing cylinder at a powder receiving position. A pressing mechanism then presses the grounds into a cake, and finally, the pressed coffee is brewed and extracted to produce coffee. However, during the process of receiving the grounds into the brewing cylinder, the grounds tend to fall unevenly, resulting in a conical shape. If the grounds fall unevenly into the brewing cylinder, the subsequent pressing process will result in a cake with some parts being denser and others being looser. During extraction, the water, due to its inertia, will flow more easily through the looser areas, resulting in more extraction in these areas and less extraction in the denser areas, leading to uneven extraction. This directly affects the stability of the extracted coffee and the taste of the resulting coffee. The pressing force and balance of the applied force can also be affected during the pressing process, leading to powder flying, resulting in poor pressing results and affecting the quality of the coffee. Summary of the Invention

[0007] The main purpose of the present invention is to provide a beverage device and a control method thereof, aiming to solve the problem in traditional technology that the brewing container needs to wait at the powder receiving position for the grinding device to grind the powder, resulting in reduced coffee preparation efficiency.

[0008] In the technical solution provided by the present invention, before the control device determines that the brewing container and the grinding device are moved to the powder receiving state, the grinding device is pre-controlled to start running, so that the grinding device can grind the granular material into powder of the required weight. Then, the brewing container and the grinding device are moved to the powder receiving state. At this time, the brewing container can receive the required weight of powder without waiting for the grinding device to grind, which helps to greatly reduce the waiting time of the brewing container in the powder receiving state, thereby helping to shorten the preparation time of the beverage, and makes the execution rhythm of each mechanism in the high-efficiency intelligent beverage equipment orderly and compact, which helps to improve the preparation efficiency of the beverage.

[0009] In the technical solution provided by the present invention, the first piston member is driven by the first driving mechanism to move up and down in the brewing container and drive the brewing container to move horizontally to achieve movement between the powder receiving position and the brewing position. During the movement, the first piston member is always located in the brewing container and there is no need to control the first piston member to enter and exit the brewing container, which helps to improve the efficiency of beverage preparation. At the same time, it simplifies the sealing between the first piston member and the brewing container and increases the service life of the first piston member.

[0010] In the technical solution provided by the present invention, the driving device is arranged into double-groove sections both horizontally and vertically, which helps to greatly reduce the reciprocating operation time of the brewing container, thereby helping to shorten the preparation time of the beverage, and makes the execution rhythm of each mechanism in the high-efficiency intelligent beverage equipment orderly and compact, which helps to improve the preparation efficiency of the beverage.

[0011] In the technical solution provided by the present invention, before the control device determines that the brewing container and the grinding device are moved to the powder receiving state, the grinding device is pre-controlled to start running, so that the grinding device can grind the granular material into powder of the required weight. Then, the brewing container and the grinding device are moved to the powder receiving state. At this time, the brewing container can receive the required weight of powder without waiting for the grinding device to grind, which helps to greatly reduce the waiting time of the brewing container in the powder receiving state, thereby helping to shorten the preparation time of the beverage, and makes the execution rhythm of each mechanism in the high-efficiency intelligent beverage equipment orderly and compact, which helps to improve the preparation efficiency of the beverage.

[0012] In the technical solution provided by the present invention, under the drive of the first driving mechanism, the first cleaning member and the brewing cylinder perform a first relative moving stroke, during which the first cleaning member can clean the area to be cleaned of the brewing cylinder, scrape out the residue accumulated in the area to be cleaned, and complete the cleaning of the area to be cleaned of the brewing cylinder; under the drive of the second driving mechanism, the first cleaning member and the second cleaning member perform a second relative moving stroke, during which the second cleaning member can scrape off the residue retained on the corresponding side surface of the first cleaning member, ensuring that the first cleaning member meets the required cleanliness, so that when the first cleaning member cleans the area to be cleaned of the brewing cylinder again, the first cleaning member will not bring external contaminants into the brewing cylinder, ensuring that each cleaning of the brewing cylinder is simple and efficient.

[0013] In the technical solution provided by the present invention, under the drive of the first driving mechanism, the cleaning member and the brewing container generate a relative motion stroke along the first direction. During this process, the first cleaning unit and the second cleaning unit both slide and abut against the area to be cleaned, and can provide at least two cleaning operations to the area to be cleaned in succession. Among them, since the second cleaning unit contacts the area to be cleaned earlier than the first cleaning unit and the second cleaning unit is softer, it can increase the contact area with the area to be cleaned and the surface fit with the area to be cleaned by elastic deformation when cleaning the area to be cleaned for the first time, which helps to increase the comprehensiveness of cleaning the area to be cleaned; then, when the first cleaning unit cleans the area to be cleaned for the second time, since the first cleaning unit is softer and has relatively greater rigidity, it can enhance the contact and abutment force between the first cleaning unit and the area to be cleaned, thereby helping to increase the thoroughness of cleaning the area to be cleaned. This application helps to optimize the cleaning effect of the area to be cleaned of the brewing container as a whole.

[0014] In the technical solution provided by the present invention, a mounting plate is provided, and the brewing cylinder and the cleaning member are both provided below the mounting plate. The brewing cylinder generates a relative movable stroke relative to the cleaning member. During this process, the area to be cleaned of the brewing cylinder can be cleaned. The area above the mounting plate will not be affected. During cleaning, the residue and powder will fall downwards. After being blocked by the mounting plate, the neatness of the structure at the upper end of the mounting plate will not be affected upwards. The present application helps to optimize the cleaning effect of the brewing component as a whole. Driven by the driving mechanism, the cleaning member and the brewing cylinder generate a relative movable stroke. During this process, the contact and abutment force between the cleaning member and the area to be cleaned is enhanced, thereby helping to increase the thoroughness of cleaning the area to be cleaned. The present application helps to optimize the cleaning effect of the area to be cleaned of the brewing cylinder as a whole.

[0015] In the technical solution provided by the present invention, after the powder material ground and discharged by the grinding device enters the brewing chamber from the feed port, it is accumulated on the bottom cavity wall of the brewing chamber in a pointed cone shape; in the process of the brewing chamber receiving the powder material, and / or after the brewing chamber completes the operation of receiving the required amount of powder material, and / or before the brewing chamber performs the powder pressing operation, since the movable part can reciprocate in the vertical direction, the powder material located at the top of the pointed cone is accelerated to slide down during its vertical movement, so that the coffee powder tends to be evenly spread on the bottom cavity wall of the brewing chamber, forming a relatively flat surface to be pressed, which is more conducive to the balanced pressing of the subsequent pressing mechanism; at the same time, the coffee powder tends to be stably fixed on the bottom cavity wall of the brewing chamber, avoiding the occurrence of flying powder or falling powder, which helps to improve the pressing reliability of the subsequent pressing mechanism as a whole, and ultimately optimizes the preparation quality of the coffee.

[0054] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments. DETAILED DESCRIPTION

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0056] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0057] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0058] Referring to Figures 1 to 3, the high-efficiency intelligent beverage device provided by the present invention includes a grinding device 200, a brewing device 300, and a control device. The grinding device 200 is used to grind granular materials to form powder; the brewing device 300 includes a brewing container 310, and the grinding device 200 and the brewing container 310 are independently provided and have a powder receiving state; the control device is used to control the grinding device 200 to pre-start grinding to form a powder of a weight not less than the required brewing weight before determining that the brewing container 310 and the grinding device 200 are in the powder receiving state; and when determining that the brewing container 310 and the grinding device 200 are in the powder receiving state, control the grinding device 200 to add powder to the brewing container 310.

[0059] In the technical solution provided by the present invention, before the control device determines that the brewing container 310 and / or the discharge part moves to the powder receiving position 110, the grinding device 200 is controlled to start running in advance, so that the grinding device 200 can grind the granular material into powder of the required weight. Then, the brewing container 310 and the grinding device 200 move to the powder receiving position 110. At this time, the brewing container 310 can receive the required weight of powder without waiting for the grinding device 200 to grind, which helps to greatly reduce the waiting time of the brewing container 310 at the powder receiving position 110, thereby helping to shorten the preparation time of the beverage, and making the execution rhythm of each mechanism in the high-efficiency intelligent beverage equipment orderly and compact, which helps to improve the preparation efficiency of the beverage.

[0060] It should be noted that this design does not limit the specific form and use of the high-efficiency intelligent beverage equipment, which can be but not limited to coffee machines, soy milk machines, wall-breaking food processors, etc. Correspondingly, the granular materials mentioned in this design can be but not limited to coffee beans, soybeans, grains, etc., and the powder materials mentioned in this design can be but not limited to coffee powder, soybean powder, grain powder, etc.

[0061] In view of the above, the present design further includes a base 100, which mainly refers to a plate-like structure, block-like structure, box-like structure, frame-like structure, etc. for mounting the grinding device 200, the brewing device 300, and the control device. The base 100 can be an integral arrangement, such as a housing of a high-efficiency smart beverage device; and / or the base 100 can include a plurality of structural units, each of which can be used, for example, to provide for the fixed installation of the grinding device 200, the fixed installation of the brewing device 300, and the fixed installation of the control device, etc. The structural units can be relatively fixed to each other, or a portion of the structural units can be configured to have a relative movable stroke relative to another portion of the structural units according to actual needs, so as to achieve the change and adjustment of the relative postures of functional components such as the grinding device 200, the brewing device 300, and the control device.

[0062] In this design, a powder receiving state exists between the grinding device 200 and the brewing container 310. This state is set when the brewing container 310 and the discharge portion are close to each other. At this time, the position of the two is the powder receiving position 110. In addition, the brewing device 300 also includes a brewing mechanism. A brewing state also exists between the brewing container 310 and the brewing mechanism. When the two switch to the brewing state, the position of the two is the brewing position 120.

[0063] The base 100 defines a powder receiving position 110 and a brewing position 120, which are spaced approximately horizontally. The powder receiving position 110 and / or the brewing position 120 can be defined by visual structures or markings. For example, as shown in FIG3 , a portion of the base 100 is hollowed out, and the hollowed-out portion defines the powder receiving position 110. Of course, the powder receiving position 110 and / or the brewing position 120 can also be defined by the installation positions of related functional components. For example, as shown in FIG3 , the installation position of the pressing mechanism 330 coincides with and is shared with the brewing position 120.

[0064] In one embodiment, the grinding device 200 includes a grinding part and a discharge part, the grinding part is used to grind the granular material to form a powder, and the discharge part is used to discharge the powder outward; at least one of the discharge part and the brewing container 310 is movably arranged relative to the other.

[0065] In specific applications, generally, at least the discharge part of the grinding device 200 is arranged at the powder receiving position 110 and is located above the feed port of the brewing container 310, so that the coffee powder ground by the grinding part and discharged by the discharge part can fall into the brewing cavity of the brewing container 310 under the action of gravity.

[0066] In view of the above, at least one of the brewing container 310 and the discharging portion is movably disposed relative to the base 100. Specifically, the brewing container 310 can be fixed relative to the base 100, and the discharging portion can be movably disposed in directions approaching and away from the brewing container 310; or the discharging portion can be fixed relative to the base 100, and the brewing container 310 can be movably disposed in directions approaching and away from the discharging portion; or both the discharging portion and the brewing container 310 can be movably disposed relative to the base 100, and the two can move toward and away from each other. For ease of understanding, the following embodiments are described as an example in which the discharging portion is fixed relative to the base 100, and the brewing container 310 can be movably disposed in directions approaching and away from the discharging portion.

[0067] In addition, it can be understood that the driving force for the movement of the brewing container 310 and / or the discharge part can come from manual operation of the user, or can be automatically carried out with the help of gravity, or in one embodiment, the high-efficiency intelligent beverage equipment also includes a first driving mechanism 320, which is connected to the movably arranged brewing container 310 and / or the discharge part to drive the brewing container 310 and the discharge part to switch between the powder receiving position 110 and the brewing position 120; the control device is also electrically connected to the first driving mechanism 320 to control the grinding part to pre-form powder of not less than the required weight before the first driving mechanism 320 drives the brewing container 310 and the discharge part to move to the powder receiving position 110; and when the first driving mechanism 320 drives the brewing container 310 and the discharge part to move to the powder receiving position 110, the discharge part is controlled to connect the powder to the brewing container 310. In this way, by actively controlling the first driving mechanism 320 through the control device, the switching timing of the relative positions of the brewing container 310 and the discharge part can be accurately grasped without the need to set up additional devices such as sensors to sense whether the brewing container 310 and the discharge part move to the powder receiving position 110 or whether they move to the brewing position 120.

[0068] When the discharge portion is fixed relative to the base 100 as described above, and the brewing container 310 is movable in directions approaching and away from the discharge portion, the first driving mechanism 320 is drivingly connected to the brewing container 310 .

[0069] In view of the above, in one embodiment, the grinding device 200 further includes a grinding container 210, a grinding mechanism 220, and a transfer container 230. The grinding container 210 defines a grinding chamber with a grinding outlet. The grinding mechanism 220 is configured to grind particulate material entering the grinding chamber to form a powder. The transfer container 230 defines a transfer chamber with a transfer inlet and a transfer outlet, the transfer inlet communicating with the grinding outlet to store the powder discharged from the grinding chamber. The grinding container 210 and the grinding mechanism 220 together constitute the grinding section, and the transfer container 230 constitutes the discharge section. Thus, under the control of a control device, the grinding mechanism 220 can be pre-activated to pre-grind a sufficient amount of powder within the grinding chamber of the grinding container 210. The powder formed within the grinding chamber can enter the transfer chamber immediately or after a certain delay, where it is securely stored. When the brewing container 310 moves to the powder receiving position 110, the transfer outlet of the transfer chamber can be connected to the brewing feed port of the brewing container 310, and the powder stored in the transfer chamber in advance can be directly and timely transferred to the brewing chamber without waiting for the grinding part to grind and make powder.

[0070] In another embodiment, the grinding device 200 further includes a grinding container 210 , a grinding mechanism 220 , a transfer container 230 , an opening and closing member 240 , and a second driving mechanism 250 . Among them, the specific settings of the grinding container 210, the grinding mechanism 220 and the transfer container 230 can refer to the above. Furthermore, the opening and closing member 240 is movably provided at the transfer discharge port to movably open and close the transfer discharge port; the second driving mechanism 250 is drivingly connected to the opening and closing member 240; wherein, the control device is electrically connected to the grinding mechanism 220 and the second driving mechanism 250 respectively, and the control device controls the grinding mechanism 220 to start, and before the brewing container 310 and the transfer container 230 move to the powder receiving position 110, controls the second driving mechanism 250 to drive the opening and closing member 240 to close the transfer discharge port; and when the brewing container 310 and the transfer container 230 move to the powder receiving position 110, controls the second driving mechanism 250 to drive the opening and closing member 240 to open the transfer discharge port.

[0071] Specifically, the specific form of the grinding container 210 is not limited, and can be set to the required shape, size, material and quantity according to actual needs. The grinding mechanism 220 includes a cutter movably arranged in the grinding chamber. The cutter can be one or more of, but not limited to, a cutter disc, a blade, a piercing knife, etc.; the movement of the cutter is related to its specific type, and is intended to grind the coffee beans into coffee powder of the desired coarseness through its own movement. The grinding mechanism 220 also includes a driving component for driving the movement of the cutter, such as a motor, a gear set, etc., which are not limited. When the control device controls the grinding mechanism 220 to start operation, it can be understood that it also controls the driving component in the grinding mechanism 220 to be powered and operated.

[0072] There is no restriction on the relative orientation relationship between the transfer container 230 and the grinding container 210. In the following embodiments, the grinding container 210 is located vertically above the transfer container 230 as an example. At this time, the grinding container 210 is located above the transfer container 230, that is, the grinding discharge port is located above the transfer feed port. With the help of gravity, the powder ground in the grinding chamber can be transferred downward to the transfer chamber.

[0073] The transfer container 230 can be integrally formed with the grinding container 210. In this case, the transfer container 230 and the grinding container 210 form a whole shell structure. The inner cavity of the whole shell structure has a feed port and a discharge port. The chamber near the feed port in the inner cavity constitutes a grinding chamber, and the chamber near the discharge port constitutes a transfer chamber.

[0074] Alternatively, the transfer container 230 may be provided separately from the grinding container 210. In this case, the transfer container 230 and the grinding container 210 are two independent shell structures, and the feed port of the transfer container 230 is connected to the discharge port of the grinding container 210. The feed port of the transfer container 230 and the discharge port of the grinding container 210 may be seamlessly connected, or connected at a certain distance from each other, or connected at a certain distance in the vertical direction. In this case, a material guide trough may be additionally provided between the feed port of the transfer container 230 and the discharge port of the grinding container 210 to guide the coffee powder discharged from the discharge port of the grinding container 210 into the transfer container 230.

[0075] The positional relationship between the transfer container 230 and the brewing container 310 can be similarly referred to above and will not be described in detail.

[0076] The opening and closing member 240 is movably arranged in the lower area of ​​the transfer container 230 so that when the opening and closing member 240 closes the discharge port of the transfer container 230, sufficient space is formed inside the transfer container 230 to store and transfer at least a preset required weight of coffee powder.

[0077] The movement of the opening and closing member 240 is not limited: in one embodiment, the opening and closing member 240 is movably disposed at the discharge port of the transfer container 230, for example, disposed on the lower side of the transfer container 230, and is movably disposed horizontally in a direction approaching and away from the discharge port of the transfer container 230, so that when the opening and closing member 240 is moved horizontally toward the discharge port of the transfer container 230, the opening and closing member 240 can cover the discharge port of the transfer container 230; and when the opening and closing member 240 is moved horizontally away from the discharge port of the transfer container 230, the opening and closing member 240 can open the discharge port of the transfer container 230. In another embodiment, the opening and closing member 240 can be flipped at the discharge port of the transfer container 230, for example, the opening and closing member 240 is plate-shaped, one end of which is rotatably mounted to an edge of the discharge port of the transfer container 230 via a structure such as a rotating shaft, thereby driving the other end of the opening and closing member 240 to flip and move toward and away from the other edge of the discharge port of the transfer container 230.

[0078] The specific configuration of the second drive mechanism 250 is related to the movement of the opening and closing member 240. For example, when the opening and closing member 240 performs linear translational movement, the second drive mechanism 250 may be, but is not limited to, a linear cylinder, or a combination of a motor and a reversing transmission assembly. The reversing transmission assembly may be, but is not limited to, a rack and pinion assembly, a screw-nut mechanism, a rocker mechanism, etc. When the opening and closing member 240 performs rotational movement, the second drive mechanism 250 may be, but is not limited to, a motor, or a combination of a linear cylinder and a reversing transmission assembly, etc., without limitation.

[0079] The control device is electrically connected to the grinding mechanism 220 and the second driving mechanism 250. The control device activates the grinding mechanism 220 and, before the brewing container 310 moves to the powder receiving position 110, controls the second driving mechanism 250 to drive the opening and closing member 240 to close the discharge port of the transfer container 230. Furthermore, when the brewing container 310 moves to the powder receiving position 110, controls the second driving mechanism 250 to drive the opening and closing member 240 to open the discharge port of the transfer container 230. Thus, when the grinding mechanism 220 is activated, it operates within the grinding chamber, grinding coffee beans into coffee powder and continuously feeding the coffee powder into the transfer container 230. When it is confirmed that the brewing container 310 has not moved to the powder receiving position 110, the control device controls the opening and closing member 240 to cover the discharge port of the transfer container 230, so that the coffee powder pre-ground by the grinding device 200 can be well pre-stored in the transfer chamber, and the pre-stored amount of coffee powder at least meets the required weight value of one brewing container 310. When it is confirmed that the brewing container 310 has moved to the powder receiving position 110, the control device controls the opening and closing member 240 to open the discharge port of the transfer container 230, so that the coffee powder pre-stored in the transfer chamber can directly enter the brewing container 310 without waiting.

[0080] Of course, in other embodiments, the transfer container 230 is provided with an opening, and other parts of the transfer container 230 except the opening are closed. The transfer container 230 is flippably arranged relative to the grinding container 210 and the brewing container 310, so as to have a feeding state in which the opening is facing and connected to the discharge port of the grinding container 210, and a discharging state in which the opening is facing and connected to the feed port of the brewing container 310; the grinding device 200 also includes a third driving mechanism, which is drivingly connected to the transfer container 230, and the control device is electrically connected to the third driving structure, so as to control the grinding mechanism 220 to start and the transfer container 230 to flip to the feeding state before the brewing container 310 and the transfer container 230 move to the powder receiving position 110; and to control the transfer container 230 to flip to the discharging state when the brewing container 310 and the transfer container 230 move to the powder receiving position 110. In this way, the transfer container 230 only needs to have one opening, which can serve as both the transfer inlet and the transfer outlet. Furthermore, there is no need to provide the opening and closing member 240 and the second drive mechanism 250 to drive the opening and closing member 240 at the transfer outlet, thereby achieving controllable and intermittent discharge of materials from the transfer container 230.

[0081] In view of the above, it can be known that the transfer container 230 and the brewing container 310 can move relative to each other, and the brewing container 310 can move toward the transfer container 230, or the transfer container 230 can move toward the brewing container 310 to deliver powder.

[0082] In a specific application, multiple brewing containers 310 can share the same preset powder receiving position 110 and brewing position 120, and move in turn to receive materials from the transfer container 230 and then return to the brewing position 120 for brewing and extraction. Multiple brewing containers 310 can be provided with overlapping parts on the path from the powder receiving position 110 to the brewing position 120 to reduce the volume of the entire machine.

[0083] In another specific application, multiple brewing containers 310 are located at their respective brewing positions 120 and remain stationary. The brewing containers 310 move the materials to the empty brewing containers 310, and transfer the materials to the empty brewing containers 310 for brewing and extraction.

[0084] The above embodiment can be applied to application scenarios where the brewing container 310 appears intermittently at the powder receiving position 110, and can also be applied to application scenarios where the brewing container 310 appears continuously at the powder receiving position 110. The application scenario where the brewing container 310 appears intermittently at the powder receiving position 110 is, for example, when the brewing device 300 as a whole or a brewing container 310 in the brewing device 300 is provided as one, and the brewing container 310 needs to be switched between the powder receiving position 110 and the brewing position 120. Therefore, when the brewing container 310 moves from the powder receiving position 110 to the brewing position 120, is in the brewing position 120, and moves from the brewing position 120 to the powder receiving position 110, the powder receiving position 110 is in an idle state. Alternatively, the brewing device 300 as a whole or at least two brewing containers 310 in the brewing device 300 are provided, and when the movable switching between the powder receiving position 110 and the brewing position 120 of each brewing container 310 cannot be completely seamless, when one brewing container 310 is moved out of the powder receiving position 110 and the other brewing container 310 has not yet moved to the powder receiving position 110, the powder receiving position 110 is in an idle state. In this case, the opening and closing member 240 is movable to cover the discharge port of the transfer container 230, ensuring that when the powder receiving position 110 is in the idle state, coffee powder does not leak out of the discharge port of the transfer container 230, resulting in waste of coffee powder.

[0085] Of course, in an application scenario where the brewing containers 310 are continuously movable at the powder receiving position 110, for example as shown in Figures 2 and 3, in one embodiment, at least two brewing containers 310 are provided, each of which is movable relative to the discharge portion, and the plurality of brewing containers 310 are located at the same position when in the powder receiving state, that is, the plurality of brewing containers 310 have the same powder receiving position 110; the control device controls the brewing containers 310 in each of the brewing devices 300 to move alternately to the powder receiving position 110 in sequence. The control device controls the grinding portion to remain activated so that the grinding portion continuously supplies powder to the discharge portion in the powder receiving state. At this time, by reasonably setting the relationship between parameters such as the brewing device 300 as a whole or the number of brewing containers 310 in the brewing device 300, the number of powder receiving positions 110, the time for the brewing container 310 to switch between the powder receiving position 110 and the brewing position 120, the time for the brewing container 310 to receive powder at the powder receiving position 110, and the time for the brewing container 310 to complete extraction and brewing at the brewing position 120, it can be ensured that when a brewing container 310 is moved out from the powder receiving position 110, another brewing container 310 is continuously connected to the powder receiving position 110, ensuring that the powder receiving position 110 is not idle, which helps to improve the coordination, continuity and compactness of the operation of the entire machine.

[0086] Specifically, in one embodiment, the high-efficiency intelligent beverage equipment also includes a grinding container 210 and a grinding mechanism 220; the grinding container 210 is formed with a grinding chamber and a grinding discharge port; the grinding mechanism 220 is arranged in the grinding chamber, and is used to grind the particulate material entering the grinding chamber to form a powder; wherein, the grinding container 210 at least has a portion of the grinding discharge port constituting the discharge portion, and the grinding mechanism 220 constitutes the grinding portion.

[0087] Or in one embodiment, the high-efficiency intelligent beverage equipment also includes a grinding container 210, a transfer container 230 and a grinding mechanism 220; the grinding container 210 is formed with a grinding chamber and a grinding discharge port; the grinding mechanism 220 is arranged in the grinding chamber, and is used to grind the particulate material entering the grinding chamber to form a powder; the transfer container 230 is formed with a transfer chamber, which is connected to the grinding chamber to store the powder discharged outward through the grinding chamber; wherein the grinding container 210 is provided with at least the portion of the grinding discharge port, and the transfer container 230 constitutes the discharge part, and the grinding mechanism 220 constitutes the grinding part.

[0088] In the above description, the grinding outlet is normally open, and the control device controls the grinding mechanism 220 to keep started, so that the grinding outlet continuously provides powder to each brewing container 310 located at the powder receiving position 110 .

[0089] The specific settings of the grinding container 210 and the grinding mechanism 220 can refer to the above and are not limited. Among them, the discharge port of the grinding container 210 is set to be normally open, and the control device controls the grinding mechanism 220 to keep it started, so that the discharge port of the grinding container 210 continuously provides powder to each of the brewing containers 310 at the powder receiving position 110. In this way, the grinding mechanism 220 can operate continuously to ensure that coffee powder is continuously formed in the grinding chamber and continuously discharged to the outside; the first driving mechanism 320 can operate continuously to ensure that when a brewing container 310 is moved out of the powder receiving position 110, another brewing container 310 is continuously connected to the powder receiving position 110.

[0090] With respect to any of the above embodiments, the specific form of the brewing container 310 is not limited and can be configured, for example, as a hollow column extending vertically, according to actual needs. Referring to Figures 2 to 4 , in this design, the brewing container 310 is vertically penetrated by a material receiving channel. The brewing device 300 further includes a first piston member 331, which is sealedly connected to the brewing container 310 and movably mounted vertically within the material receiving channel. The upper end surface of the first piston member 331 is used to receive powdered material entering the material receiving channel.

[0091] Furthermore, when the brewing container 310 is receiving coffee powder and / or when the brewing container 310 completes the operation of receiving coffee powder of the required weight value, the control device can control the first piston member 331 to move up and down, driving the powder to move up and down, so that the powder stacked in a pointed cone shape on the upper end surface of the first piston member 331 can be driven to move and evenly flattened on the upper end surface of the first piston member 331.

[0092] Furthermore, as described above, the brewing device 300 further includes a pressing mechanism 330. The pressing mechanism 330 may include the first piston 331 described above. Furthermore, the pressing mechanism 330 may also include a second piston 332. The second piston 332 is positioned corresponding to the brewing position 120 and is movably mounted on the base 100 in an up-down direction. When the brewing container 310 moves to the brewing position 120, the second piston 332 moves downward to extend into the material receiving channel and, together with the first piston 331, presses the powdered material. When the brewing container 310 moves from the powder receiving position 110 to the brewing position 120, the first piston 331 moves synchronously and is driven to the brewing position 120. The second piston 332 moves downward to extend into the material receiving channel. Furthermore, the second piston 332 and / or the first piston 331 move toward each other to press the powdered material therebetween to form a powder cake. By pressing the dispersed powder into a cake, on the one hand, it can avoid the formation of a channel effect in the subsequent brewing process, which will result in incomplete brewing of the coffee powder; on the other hand, it ensures that sufficient brewing pressure is formed during the brewing process, thereby improving the brewing quality.

[0093] Furthermore, the driving force sources of the first piston member 331 and the second piston member 332 can be separately configured drive components, or in one embodiment, the first drive mechanism 320 is also drivably connected to the first piston member 331 to drive the first piston member 331 to move in the vertical direction; the brewing device 300 also includes a fourth drive mechanism 340, which is disposed on the base 100 and drivably connected to the second piston member 332 to drive the second piston member 332 to move in the vertical direction. In this way, the movement of the first piston member 331 can directly rely on the existing first drive mechanism 320, and only the fourth drive mechanism 340 needs to be additionally provided for the second piston member 332, thereby achieving independent drive of the first piston member 331 and the second piston member 332, and contributing to the simplification of the structure of the entire device and the convenience of operation.

[0094] In addition, referring to Figures 3 to 5, in one embodiment, the brewing container 310 has a feed end, i.e., the end of the brewing container 310 where its feed opening is located. The brewing device 300 also includes a scraper 350 disposed on the base 100 and located between the powder receiving position 110 and the brewing position 120. The scraper 350 is configured to interfere with the feed end of the brewing container 310 as it moves from the brewing position 120 to the powder receiving position 110, thereby removing residual material from the feed end. The scraper 350 can interfere with the feed end of the brewing container 310 as the brewing container 310 moves past, and this interference can remove any residual material from the feed end of the brewing container 310, allowing the brewing container 310 to return to the powder receiving position 110 relatively clean. In practical applications, the scraper 350 can be block-shaped and extend along the circumference of the brewing container 310 in a ring shape or an arc shape. The scraper 350 can be configured to slide against the feed end of the brewing container 310 as it passes by, thereby scraping off dirt remaining at the feed end during the sliding contact process.

[0095] In addition, in one embodiment, the brewing device 300 further includes a liquid supply assembly (not shown in the drawings) and a liquid discharge assembly (not shown in the drawings). The liquid supply assembly is disposed on the base 100 and is used to supply brewing liquid into the brewing container 310; the liquid discharge assembly is disposed on the brewing container 310 and is used to discharge the brewed beverage in the brewing container 310 to the outside. The liquid supply assembly and / or the liquid discharge assembly may form a liquid flow channel connected to the brewing chamber of the brewing container 310, so that brewing liquid (e.g., hot water, etc.) outside the brewing chamber can be supplied to the brewing chamber through the liquid flow channel, and / or the brewed beverage in the brewing chamber can be discharged to the outside of the brewing chamber. The liquid passage can be an additional piping structure, or the liquid passage of the liquid supply assembly can be directly provided on the first piston member 331, and the liquid passage of the liquid discharge assembly can be directly provided on the second piston member 332. Arranging the liquid passage with the first piston member 331 and / or the second piston member 332 helps simplify and compact the overall structure. In addition, the liquid supply assembly and / or the liquid discharge assembly also include drive components such as pumps to achieve directional flow of the brewing liquid and / or beverage through the liquid passage.

[0096] Next, in one embodiment, the control device is electrically connected to the liquid supply assembly and the liquid discharge assembly, respectively, to control the liquid supply assembly to activate when the brewing container 310 moves to the brewing position 120, to control the liquid discharge assembly to activate when brewing in the brewing container 310 is determined to be complete, and to control the first piston member 331 to move upward to the feed end of the brewing container 310 after the liquid discharge assembly has discharged the beverage in the brewing container 310. In this way, when brewing in the brewing container 310 is determined to be complete and the beverage has been discharged, the first piston member 331 can interfere with the inner wall of the brewing chamber, thereby scraping off dirt remaining on the inner wall of the brewing chamber and moving the dirt upward to the feed end of the brewing container 310, where it can be scraped off by the scraping member 350.

[0097] Specifically, referring to Figures 5 and 6, in one embodiment, to achieve the above functions, the first driving mechanism 320 includes a piston rod 321, a driver 322, a driving gear 323, a driven gear 324, a driving rod 325, a linkage member 326 and a guide member 327. The cam 326 is connected to the base 100 and has a rotation output shaft rotatable along the vertical axis. The rotation output shaft is located beside the piston rod 321 and extends side by side with the piston rod 321. The driving gear 323 is coaxially mounted on the rotation output shaft. The driven gear 324 is located beside the driving gear 323 and meshes with the driving gear 323. The driven gear 324 is provided with an internal thread. The driving rod 325 is provided with an external thread, which is threadedly connected to the internal thread of the driven gear 324 so as to be driven by the driver 322 to rotate along the vertical axis and translate along the vertical direction respectively. The linkage member 326 linkage-connects the piston rod 321 and the driving rod 325. The guide member 327 is fixed relative to the brewing container 310 and is connected to the driving rod 325.

[0098] One of the connections between the guide member 327 and the drive rod 325 is provided with a guide groove 328, and the other is provided with a guide protrusion that slidably engages with the guide groove 328. The guide groove 328 includes a first groove section 328a extending in the vertical direction. When the guide protrusion slides along the first groove section 328a, the rotational motion of the drive rod 325 along the vertical axis is converted into vertical translational motion of the first piston member 331. The first groove section 328a can be configured to extend helically in the vertical direction and in the circumferential direction of the drive rod 325, thereby converting the rotational motion of the drive rod 325 into the vertical translational motion of the first piston member 331. The guide groove 328 also includes a second groove section 328b extending along the circumference of the driving rod 325, and a third groove section 328c extending along the vertical direction. The second groove section 328b has a first end and a second end that are oppositely arranged in the circumference of the driving rod 325. The first end is connected to the third groove section 328c, and the second end is connected to the first groove section 328a, so that when the guide protrusion is located at the first end, the brewing container 310 is driven to be located at the brewing position 120, and when the guide protrusion is located at the second end, the brewing container 310 is located at the powder receiving position 110.

[0099] Specifically, the guide groove 328 further includes an entry groove section 328e that is connected to the first end of the second groove section 328b. When the guide protrusion enters the entry groove section 328e and slides to the first end of the second groove section 328b, the brewing container 310 is in the brewing position 110.

[0100] When the guide protrusion moves within the second groove section 328b and slides from the second end to the first end, the brewing container 310 rotates from the powder receiving position 110 to the brewing position 120. Furthermore, along the circumference of the driving rod 325, the second groove section 328b gradually extends obliquely toward one axial end of the driving rod 325, helping to slow down the rotation speed of the brewing container 310 from the powder receiving position 110 to the brewing position 120, thereby making the rotation process of the brewing container 310 more stable.

[0101] When the guide protrusion moves in the first groove section 328a, the guide protrusion slides back and forth up and down in the first groove section 328a, thereby driving the first piston member 331 to move vertically in the brewing chamber.

[0102] The guide groove 328 also includes a fourth groove section 328d, which extends circumferentially along the drive rod 325 and connects the first groove section 328a and the third groove section 328c at one end away from the second groove section 328b. The first, second, third, and fourth groove sections 328a, 328b, 328c, and 328d essentially form an annular shape. Therefore, when the guide protrusion slides from the second groove section 328b along the fourth groove section 328d and finally to the first groove section 328a, the brewing container 310 returns from the brewing position 120 to the powder receiving position 110.

[0103] When the guide protrusion moves in the third groove section 328c, the brewing container 310 is in the brewing position 120, and the guide protrusion slides back and forth up and down in the third groove section 328c, which can drive the first piston member 331 to move vertically in the brewing chamber, adjust the position of the first piston member 331 in the brewing chamber, cooperate with the second piston member 332 to perform a pressing stroke, or push the coffee grounds in the brewing wall upward.

[0104] At the connection point between the second groove section 328b and the third groove section 328c of the present invention, a through opening is provided from the upper end of the third groove section 328c, which penetrates the driving rod 325 upward, so that the guide protrusion of the guide member 327 can be installed downward from the through opening into the guide groove 328. In other embodiments, the through opening may not be provided. In this case, the guide member 327 needs to be first sleeved on the outer periphery of the driving rod 325, and then the guide protrusion is pushed inward from the outer periphery of the guide member 327 into the guide groove 328.

[0105] Among them, the first groove section 328a and the third groove section 328c are roughly parallel in the vertical direction, the fourth groove section 328 connecting the first groove section 328a and the lower end of the third groove section 328c are vertically connected between the two, and the second groove section 328b connecting the first groove section 328a and the upper end of the third groove section 328c are connected between the two at an inclined angle, and the top of the third groove section 328c is higher than the top of the first groove section 328a. The inclined second groove section 328b enables the guide protrusion of the guide member 327 to play a certain buffering role when sliding in the second groove section 328b.

[0106] Specifically, the driver 322 is, for example, a motor, which can be disposed on the upper side, lower side, or side of the brewing container 310. The motor's rotational output shaft extends in the vertical direction so as to rotate along its own axis during startup. The drive rod 325 also extends in the vertical direction and is directly or indirectly connected to the rotational output shaft so as to convert the rotation of the rotational output shaft into its own rotation. The drive rod 325 and the first piston member 331 can also be directly or indirectly connected. The guide member 327 is fixed relative to the brewing container 310 so that when the guide protrusion slides along the guide groove 328 and is guided, the drive rod 325 is driven to move relative to the brewing container 310. The first groove section 328a extends in the vertical direction so that the vertical axis rotation of the drive rod 325 can be converted into vertical translation as the guide protrusion slides along the first groove section 328a, ultimately achieving the purpose of driving the first piston member 331 to move in the vertical direction.

[0107] The guide protrusion is fixedly arranged in the guide member 327, and the guide member 327 is fixedly arranged relative to the base 100. The driver 322 is used to drive the driving rod 325, driving the guide groove 328 of the driving rod 325 to slide along the guide protrusion. The guide protrusion moves from the first end of the second slot segment 328b along the third slot segment 328c to the fourth slot segment 328d until it moves to the connection between the fourth slot segment 328d and the first slot segment 328a. At this time, the driver 322 drives the driving rod 325 to rotate in the first rotation direction; when moving from the connection between the fourth slot segment 328d and the first slot segment 328a to the second end of the second slot segment 328b and further to the first end of 328b, the driver 3 22 drives the driving rod 325 to rotate in the opposite direction in a second rotation direction opposite to the first rotation direction. In order to prevent the second slot segment 328b from reversing toward the second end of the second slot segment 328b when the driver 322 reverses at the first end of the second slot segment 328b and the connection between the fourth slot segment 328d and the first slot segment 328a, and to prevent the guide protrusion from moving in the opposite direction toward the third slot segment 328c when the guide protrusion is located at the connection between the fourth slot segment 328d and the first slot segment 328a, a limiting portion is provided at the second slot segment 328b and the connection between the fourth slot segment 328d and the first slot segment 328a, so that at the above two position points, even if the driver 322 reverses its rotation, it will not return along the original path.

[0108] The third groove section 328c is provided with a brewing position point in its stroke. When the guide protrusion is located at the brewing position point, the first piston member 331 and the second piston member 332 are arranged in the brewing container 310 for extraction. When the third groove section 328c continues to move upward and the guide protrusion is located at the connection between the third groove point 328c and the fourth groove section 328d, the first piston member 331 pushes the extracted coffee grounds upward out of the brewing container 310.

[0109] By adjusting the gear ratio between the driving gear 323 and the driven gear 324, the rotational deceleration or acceleration of the output shaft to the drive rod 325 can be achieved accordingly. The arrangement of internal and external threads facilitates the combined motion of the drive rod 325, which, driven by the first driver 322, the driving gear 323, and the driven gear 324, can achieve both vertical axial rotation and vertical translation, converting the motion into helical translation of the drive rod 325. In this case, the first groove segment 328a can be configured to extend substantially parallel to the axial direction of the drive rod 325, making it easier to process and shape.

[0110] In addition, in one embodiment, the driver 322 and the drive rod 325 are arranged on the side of the brewing container 310, which can reduce the space occupied by the driver 322 and the drive rod 325 in the vertical direction of the brewing container 310. At this time, the driving mechanism also includes a piston rod 321 and a linkage member 326. The piston rod 321 is fixedly connected to the first piston member 331 and is arranged side by side with the drive rod 325; the linkage member 326 links the drive rod 325 and the piston rod 321. The linkage member 326 can be a connecting rod extending in the horizontal direction, which is fixedly connected to the piston rod 321 and the drive rod 325 respectively, so as to accurately transmit the up and down movement of the drive rod 325 to the piston rod 321, drive the piston rod 321 to move up and down, and finally realize the driving of the up and down movement of the first piston member 331.

[0111] Furthermore, in one embodiment, the brewing container 310 is made of ceramic. Ceramic materials have good rigidity and hardness, and are more wear-resistant, which helps to increase the service life of the brewing container 310. Furthermore, ceramic materials have good thermal insulation properties, which can reduce the heat exchange between the coffee beverage in the brewing chamber and the external environment during the extraction and brewing process, thereby preventing the coffee beverage from cooling down and degrading its taste.

[0112] In view of the above, in a preferred embodiment of the present invention, the time T1 (usually about 6-8 seconds) required to grind coffee powder to extract each cup of coffee liquid is required, and after a single brewing container 310 returns to the brewing position 120, it performs brewing and extraction until the coffee grounds are discharged for a time T2 (usually 25 seconds) (these times can also be preset and adjusted according to the needs of the machine), that is, each time the coffee liquid is extracted, approximately 3-4 cups of coffee powder can be ground. The maximum number of brewing containers 310 that can be matched with one grinding mechanism 220 and one transfer container 230 is 3, so that the brewing container 310 can transfer new coffee powder with the minimum waiting time after each extraction is completed, so that the grinding mechanism 220 and the brewing container 310 can work almost uninterruptedly when the cup is continuously discharged, thereby maximizing the brewing efficiency.

[0113] The coffee machine can be set to either single or multiple brewing modes to meet brewing needs at different times. The operator can independently select single or multiple brewing container 310 mode. Once activated, if the operator continuously inputs a preset number of cups to be brewed, the machine automatically activates multiple brewing container 310 mode, maximizing the coffee machine's operating efficiency. The multiple brewing container 310 also allows for the use of a single brewing container 310.

[0114] Single Brewing Mode Matches Multiple Brewing Modes. Except for the initial state, during normal operation, only one brewing container 310 needs to be loaded with new powder after the extraction is completed. The new powder has been pre-ground by the grinding device 200 and placed in the brewing container 310. In this way, no matter whether the brewing container 310 receives powder from the powder receiving position 110 or delivers powder to the brewing position 120, there will be no confusion or errors.

[0115] Based on any of the above embodiments of the beverage preparation machine, referring to FIG. 7 to FIG. 9 , the present invention further provides a control method for a high-efficiency intelligent beverage device, comprising:

[0116] Step S110: upon receiving a working instruction, controlling the grinding device 200 to start operation;

[0117] In this embodiment, the work instruction can be manually triggered by the user or periodically triggered by the control device according to a pre-set period. The manual triggering method is not limited and can be triggered by pressing a physical button and / or a virtual button on the outer surface of the device, or by a mobile terminal connected to the control device via wireless communication, or when the device is additionally equipped with a voice recognition module or an image recognition module, by outputting a set voice or setting an action, etc., without limitation.

[0118] After the working instruction is triggered, the control device controls the grinding device 200 to start operation, including the preset unloading mechanism in the grinding device 200 obtaining and transferring the coffee beans into the grinding chamber, the grinding mechanism 220 grinding the coffee beans in the grinding chamber to the required degree, and the preset discharging mechanism in the grinding device 200 transferring the coffee powder obtained after grinding from the grinding chamber to the outside, etc.

[0119] Among them, when, as described above, the grinding device 200 includes a grinding container 210, a grinding mechanism 220, a transfer container 230, an opening and closing part 240 and a second driving mechanism 250, please refer to Figure 8, the step S110 can specifically be step S210: when receiving a work instruction, the grinding mechanism 220 is controlled to start running and the second driving mechanism 250 is controlled to drive the opening and closing part 240 to close the transfer discharge port.

[0120] Step S120: When it is determined that the powder material ground by the grinding device 200 is not less than a preset required weight value, the brewing container 310 and the grinding device 200 are controlled to switch to a powder receiving state to receive the powder material;

[0121] Optionally, after step S120 , there is a step S130 : controlling the brewing container 310 to move to the brewing position 120 .

[0122] In this embodiment, a determination is first made as to whether the weight of the coffee powder ground by the grinding mechanism 220 is at least greater than a preset required weight value. The determination method is not limited; for example, the amount of ground coffee powder can be estimated by the operating time of the grinding mechanism 220, or the amount of ground coffee powder can be accurately measured by an additional sensor. The sensor can be, but is not limited to, a weighing sensor, such as a weight sensor or a pressure sensor, or an imaging sensor that can capture image information of the coffee powder during discharge and / or stacking. The required weight value can be preset based on user requirements, and the required weight value can at least meet the user's single brewing requirements.

[0123] Then, when it is determined that the powder formed by the grinding device 200 is not less than the preset required weight value, the first driving mechanism 320 can be controlled to drive the brewing container 310 to move to the powder receiving position 110. In the specific application process:

[0124] Referring to FIG8 , when the grinding device 200 includes the grinding container 210 , the grinding mechanism 220 , the transfer container 230 , the opening and closing member 240 , and the second driving mechanism 250 , the steps S110 to S120 may be specifically performed as follows:

[0125] Step S210: upon receiving a work instruction, controlling the grinding mechanism 220 to start operation and driving the opening and closing member 240 to close the transfer outlet;

[0126] Step S220: When it is determined that the powder stored in the transfer container 230 is not less than the preset required weight value or the grinding mechanism 220 has been running for a preset time, the brewing container 310 and / or the transfer container 230 is controlled to move to a powder receiving state, and the opening and closing member 240 is controlled to open the transfer discharge port to receive the powder.

[0127] Once the grinding mechanism 220 is activated, it operates within the grinding chamber, grinding coffee beans into coffee powder and continuously feeding the coffee powder into the transfer container 230. When it is determined that the brewing container 310 has not moved to the powder receiving position 110, the control device controls the opening and closing member 240 to close the discharge port of the transfer container 230, allowing the coffee powder pre-ground by the grinding mechanism 200 to be properly pre-stored within the transfer chamber, with the pre-stored amount of coffee powder meeting the required weight of at least one brewing container 310. When it is determined that the brewing container 310 has moved to the powder receiving position 110, the control device controls the opening and closing member 240 to open the discharge port of the transfer container 230, allowing the coffee powder pre-stored in the transfer chamber to enter the brewing container 310 directly without waiting.

[0128] 9 , when, as described above, at least two brewing containers 310 are provided, the number of powder receiving positions 110 is less than the number of brewing devices 300; the grinding device 200 includes a grinding container 210, a grinding mechanism 220, a transfer container 230, an opening and closing member 240, and a second driving mechanism 250, and the control device controls the brewing containers 310 in each brewing device 300 to move alternately to the powder receiving positions 110 in sequence, step S120 may be specifically performed as follows:

[0129] Step S320: Controlling each brewing container 310 to alternately switch between the powder receiving state and the brewing state, so that when one brewing container 310 moves to the brewing state, the other brewing container 310 moves to the powder receiving state.

[0130] In this embodiment, the discharge port of the grinding container 210 is normally open, and the control device controls the grinding mechanism 220 to remain activated so that the discharge port of the grinding container 210 continuously supplies powder to each brewing container 310 located at the powder receiving position 110. In this way, the grinding mechanism 220 can operate continuously, ensuring that coffee powder is continuously formed in the grinding chamber and continuously discharged. The first drive mechanism 320 can also operate continuously, ensuring that when a brewing container 310 is moved out of the powder receiving position 110, another brewing container 310 can be continuously moved into the powder receiving position 110, thereby improving the coordination, continuity, and compactness of the entire machine's operation.

[0131] In addition, the present invention also provides a control method for a high-efficiency smart beverage device, which can be the high-efficiency smart beverage device described above, specifically including a grinding device 200 and a brewing device 300. Referring to FIG. 10 , the control method for the high-efficiency smart beverage device includes the following steps:

[0132] Step S410: Turn on the high-efficiency smart beverage device;

[0133] Step S420: When the brewing device 300 and the grinding device 200 are at the initial positions, controlling the grinding device 200 to start grinding the powder;

[0134] Step S430: After the ground powder is transferred from the grinding device 200 to the brewing device 300, the brewing device 300 is controlled to extract the material;

[0135] Step S440: while the brewing device 300 is extracting the material, controlling the grinding device 200 to continue grinding the powder material to be extracted next time, and completing the grinding and storing the powder material before the brewing device 300 completes the extraction;

[0136] Step S450: After the extraction in the brewing device 300 is completed, the powder residue in the brewing device 300 is poured out and the ground powder is transferred into the brewing device 300 for the next extraction.

[0137] In this embodiment, after receiving a user-triggered power-on command, the control device controls the high-efficiency intelligent beverage device to power on. The brewing device 300 and the grinding device 200 are controlled to move to their initial positions. After determining that the brewing device 300 and the grinding device 200 are in their initial positions, the control device controls the grinding device 200 to begin grinding the powder. The grinding device 200 and the brewing device 300 then switch to a powder receiving state, transferring the ground powder from the grinding device 200 to the brewing device 300, thereby receiving the powder from the brewing container 310 and extracting the powder within the brewing container 310. Using the extraction time of the brewing container 310, the control device controls the grinding device 200 to continue grinding to obtain the next amount of powder to be extracted. This allows the brewing container 310 to move to the powder receiving position 110 again, allowing the grinding device 200 to directly feed the brewing container 310 with the required powder without waiting.

[0138] Specifically, in one embodiment, the brewing device 300 performs an extraction for a time period of T1, and the grinding device 200 grinds the powder for a single brew for a time period of T2, wherein T1 is greater than or equal to twice T2. This allows the grinding device 200 to grind the powder sufficiently in time to prepare the powder for the next brewing.

[0139] In addition, in one embodiment, the high-efficiency intelligent beverage device further includes a transfer container 230 disposed between the grinding device 200 and the brewing device 300. The specific configuration of the transfer container 230 can be referred to above. In the grinding device 200, the powder ground by the grinding mechanism 220 in the grinding container 210 is first stored in the transfer container 230 before being transferred to the brewing device 300. This facilitates the pre-receiving of the powder pre-ground by the grinding mechanism 220, thereby not occupying the space in the grinding container 210 but also enabling the transfer of the powder. After the brewing container 310 moves to the powder receiving state, the required powder can be directly supplied to the brewing container 310 through the transfer container 230.

[0140] In practical applications, in view of the above, the transfer container 230 is disposed within the grinding device 200, that is, the transfer container 230 and the grinding container 210 are integrally formed. Alternatively, the transfer container 230 is disposed independently of the grinding device 200, that is, the transfer container 230 and the grinding container 210 are disposed independently. Furthermore, as needed, the transfer container 230 can be relatively displaced from the brewing device 300.

[0141] When two brewing devices 300 are provided as described above, before performing the extraction work, the brewing device 300 controls the operation time of the grinding mechanism 220 to keep the ground powder in the transfer container 230, so that when the brewing device 300 moves to the powder receiving position 110, the transfer container 230 directly delivers the required powder to the brewing device 300.

[0142] In view of the above, in one embodiment, the system of the high-efficiency intelligent beverage device is preset to have a single brewing mode and a multi-brewing mode. The single brewing mode controls the switching of a single brewing container 310 between the powder receiving position 110 and the brewing position 120, with the grinding device 200 and other related mechanisms operating in conjunction; the dual brewing mode controls the switching of at least two brewing containers 310 between the powder receiving position 110 and the brewing position 120, with the grinding device 200 and other related mechanisms operating in conjunction. In actual use, the user can independently select to activate the single brewing mode or the multi-brewing mode, and the high-efficiency intelligent beverage device can switch to the single brewing mode or the multi-brewing mode in response to the user's selection.

[0143] Furthermore, in one embodiment, after the step S410 of powering on the high-efficiency smart beverage device, the process further includes:

[0144] Step S411: When it is determined that the number of cups of beverages input by the user reaches a preset number of cups, the high-efficiency intelligent beverage device is controlled to automatically start a multi-brew mode.

[0145] Refer to the beverage preparation device shown in Figures 11 to 17. The beverage preparation device includes a body and a self-cleaning brewing system provided on the body. It is understood that the beverage preparation device can be, but is not limited to, electrical appliances such as coffee machines, soy milk machines, and grain wall breaking machines. Take the beverage preparation device as an example: when the beverage preparation device directly processes coffee powder, the self-cleaning brewing system is directly connected to the external coffee powder and extracts and brews the external coffee powder. The external powder can be, for example, coffee capsules, small cans of coffee powder, bagged coffee powder, etc. When the beverage preparation device directly processes coffee beans, the beverage preparation device can also include a grinding device, which is connected to the coffee beans and grinds the coffee beans, or coffee powder of a desired coarseness; the discharge port of the grinding device is connected to the feed port of the self-cleaning brewing system, and the coffee powder obtained by the grinding device is connected to the self-cleaning brewing system for brewing to extract and brew the coffee powder.

[0146] Since the main invention of the present application is to improve the self-cleaning brewing system, the self-cleaning brewing system will be described mainly with reference to the accompanying drawings in the following embodiments.

[0147] Please refer to Figures 11 to 17. The present invention provides a self-cleaning brewing system, which has a first direction and a second direction that are arranged in a cross-direction. The self-cleaning brewing system includes a brewing container 310, a first cleaning member 400, and a second cleaning member 500. The brewing container 310 is formed with a brewing cavity, and one end of the brewing cavity in the first direction is open. The brewing container 310 defines an area to be cleaned at least at the open end; the first cleaning member 400 is located on one side of the area to be cleaned in the first direction, and at least one of the first cleaning member 400 and the brewing container 310 is movable relative to the other along the second direction, so that the first cleaning member 400 and the brewing container 310 have a first relative movable stroke. In the first relative movable stroke, the end surface of the first cleaning member 400 is in contact with the area to be cleaned. The second cleaning member 500 slides and abuts against the area to be cleaned to remove dirt from the area to be cleaned; the second cleaning member 500 is adjacent to one side of the first cleaning member 400 in the second direction, and at least one of the second cleaning member 500 and the first cleaning member 400 is movably arranged relative to the other along the first direction, so that the second cleaning member 500 and the first cleaning member 400 have a second relative moving stroke, and in the second relative moving stroke, the second cleaning member 500 slides and abuts against the side surface of the first cleaning member 400 to remove dirt from the side surface of the first cleaning member 400.

[0148] In the technical solution provided by the present invention, under the drive of the lower driving mechanism 2501, the first cleaning member 400 and the brewing container 310 perform a first relative moving stroke. During this process, the first cleaning member 400 can clean the area to be cleaned of the brewing container 310, scrape out the residue accumulated in the area to be cleaned, and complete the cleaning of the area to be cleaned of the brewing container 310; under the drive of the upper driving mechanism 2502, the first cleaning member 400 and the second cleaning member 500 perform a second relative moving stroke. During this process, the second cleaning member 500 can scrape off the residue retained on the corresponding side surface of the first cleaning member 400, ensuring that the first cleaning member 400 meets the required cleanliness, so that when the first cleaning member 400 cleans the area to be cleaned of the brewing container 310 again, the first cleaning member 400 will not bring external contaminants into the brewing container 310, ensuring that each cleaning of the brewing container 310 is simple and efficient.

[0149] Referring to Figures 11 to 13, in this design, the self-cleaning brewing system also includes a base 100, which mainly provides a mounting carrier for functional components such as the brewing container 310, the first cleaning member 400, and the second cleaning member 500. The base 100 can be, but is not limited to, one or more of a plate-like structure, a block-like structure, a box-like structure, and a frame-like structure. The base 100 can be a structure specifically set up for the self-cleaning brewing system. When the self-cleaning brewing system is then applied to a beverage preparation device, the base 100 is fixedly or movably mounted to the body of the beverage preparation device. Of course, the base 100 can also be directly used in a fixed part of the beverage preparation device, such as the body, to help integrate the functional components of the self-cleaning brewing system, such as the brewing container 310, the first cleaning member 400, and the second cleaning member 500, onto the body.

[0150] For ease of understanding, in the following embodiments, a self-cleaning brewing system is placed horizontally on a platform as an example. The self-cleaning brewing system therefore has a horizontal plane and an up-down direction. Among them, the first direction is the up-down direction, and the second direction is a direction on the horizontal plane. However, it should be noted that the above does not constitute a limitation on the specific application of the first direction and the second direction. In other applications, the first direction and the second direction may be directions other than the horizontal plane and the up-down direction. In view of the above, the relative movement direction of the first cleaning member 400 and the second cleaning member 500 is the first direction, and the relative movement direction of the first cleaning member 400 and the brewing container 310 is the second direction. The first direction and the second direction are not parallel to each other.

[0151] In view of the above, the brewing container 310 can be specifically disposed on the lower side of the base 100, and the aforementioned grinding device can be specifically disposed on the upper side of the base 100. In this way, the coffee powder ground by the grinding device can be added to the brewing container 310 by virtue of gravity. The brewing container 310 is suspended below the base 100, and the first cleaning member 400 can be disposed between the base 100 and the brewing container 310, that is, above the brewing container 310.

[0152] Next, the first relative movement stroke can be formed by one of the first cleaning member 400 and the brewing container 310 being movable in the second direction, or by both the first cleaning member 400 and the brewing container 310 being movable in the second direction, and the two being movable toward each other and away from each other. For ease of understanding, the following embodiments are described as an example in which the first cleaning member 400 is fixed relative to the base 100 and the brewing container 310 is movable relative to the base 100 in the second direction.

[0153] Specifically, as shown in Figures 12 to 13, the base 100 is arranged in a plate shape and extends roughly along the horizontal plane. The base 100 is defined with a powder receiving position 110 and a brewing position 120 that are spaced apart, and a second direction is defined between the powder receiving position 110 and the brewing position 120.

[0154] In addition, the source of the driving force for the above-mentioned first relative movable stroke is not limited, and can be, for example, achieved by manual operation by the user, driven by gravity, etc., or in one embodiment, the self-cleaning brewing system further includes a lower driving mechanism 2501, and the lower driving mechanism 2501 is drivingly connected to the movably arranged first cleaning member 400 and / or the brewing container 310. Similarly, the source of the driving force for the above-mentioned second relative movable stroke is not limited, and can be, for example, achieved by manual operation by the user, driven by gravity, etc., or in one embodiment, the self-cleaning brewing system further includes an upper driving mechanism 2502, which is provided on the base 100 and is drivingly connected to the movably arranged first cleaning member 400 and / or the second cleaning member 500.

[0155] Driven by the lower driving mechanism 2501, the brewing container 310 is movably switched between the powder receiving position 110 and the brewing position 120. The lower driving mechanism 2501 can drive the brewing container 310 to perform linear translation between the powder receiving position 110 and the brewing position 120. In this case, the linear connection direction between the powder receiving position 110 and the brewing position 120 constitutes the second direction. Of course, the lower driving mechanism 2501 can also drive the brewing container 310 to perform curved translation or rotational motion between the powder receiving position 110 and the brewing position 120. In this case, the curved connection direction between the powder receiving position 110 and the brewing position 120 constitutes the second direction.

[0156] The lower drive mechanism 2501 is specifically configured to suit the motion of the brewing container 310. When the brewing container 310 performs linear translation, the lower drive mechanism 2501 can be configured directly as a driver, such as a linear cylinder or motor, or as a combination of a driver and a transmission assembly. The transmission assembly can be a gear train, a screw-nut mechanism, a pulley assembly, a rack-and-pinion assembly, or the like. Of course, when the brewing container 310 performs curved translation or rotational motion at a certain angle, the lower drive mechanism 2501 can also be configured directly as a driver, or as a combination of a driver and a transmission assembly.

[0157] 12 to 14 , in view of the above, the specific configuration of the first cleaning member 400 is as follows:

[0158] The first cleaning member 400 can be fixedly arranged on the moving path of the brewing container 310, that is, located on any side of the powder receiving position 110 and / or the brewing position 120 in the second direction, so that under the drive of the lower driving mechanism 2501, the brewing container 310 can move through the first cleaning member 400 without additionally changing the moving path of the brewing container 310 or additionally setting up other driving mechanisms.

[0159] Furthermore, in one embodiment, the first cleaning member 400 is fixedly disposed between the powder receiving position 110 and the brewing position 120. Thus, when the lower drive mechanism 2501 drives the brewing container 310 back and forth between the powder receiving position 110 and the brewing position 120, it can move past the first cleaning member 400 without further extending the movement path of the brewing container 310. Furthermore, when moving from the powder receiving position 110 to the brewing position 120, the first cleaning member 400 can scrape any coffee powder that may remain in the area to be cleaned of the brewing container 310 and sweep it into the brewing chamber of the brewing container 310. When returning to the powder receiving position 110 via the brewing position 120, the first cleaning member 400 can scrape away any coffee residue remaining in the area to be cleaned of the brewing container 310.

[0160] And / or in one embodiment, the first cleaning member 400 is positioned closer to the brewing position 120 than to the coffee powder receiving position 110. At the brewing position 120, hot water or hot milk is introduced into the brewing chamber of the brewing container 310 to extract and brew the coffee powder. This causes the temperature in the brewing chamber to be high and the remaining coffee grounds to be softened. At this time, by positioning the first cleaning member 400 close to the brewing position 120, the softened coffee grounds can be cleaned immediately, avoiding cleaning the coffee grounds after they have cooled and hardened, which would increase the difficulty of cleaning the coffee grounds.

[0161] A brewing chamber for receiving coffee powder is formed within the brewing container 310. It is understood that the brewing container 310 can be configured as a semi-enclosed container having an inlet and an outlet. Alternatively, in one embodiment, the brewing container 310 includes a cylinder 311 and a first piston member 331. The cylinder 311 is provided with a channel 211 extending along a first direction. The first piston member 331 is reciprocally movable in the first direction within the channel 211. The first piston member 331 is sealingly connected to the inner wall of the channel 211 to seal the lower section of the channel 211, thereby enclosing the aforementioned brewing chamber.

[0162] The first piston member 331 is provided with a plurality of water inlet holes for admitting external water into the channel 211. The external water may be, for example, hot water or hot milk. The external water may be connected to the water inlet holes via a structure such as a pipe.

[0163] In a specific application, the end surface of the cylinder 311 that is close to the first cleaning member 400 along the first direction is the first end surface, and the first end surface defines the area to be cleaned. In this way, the first cleaning member 400 can remove coffee powder that has fallen on the first end surface, or coffee residue that has been discharged from the brewing chamber and retained on the first end surface. And / or when the first piston member 331 moves to extend out of the first end surface, the end surface of the first piston member 331 defines the area to be cleaned. When the brewing container 310 completes a single brewing and discharges the coffee beverage, the third drive mechanism can drive the first piston member 331 toward the first end surface, pushing out the coffee residue remaining on the inner wall of the channel 211 and accumulating it on the end surface and / or the first end surface of the first piston member 331 for removal by the first cleaning member 400.

[0164] The third drive mechanism is disposed on the base 100 and is drivingly connected to the first piston member 331. It is understood that the third drive mechanism and the lower drive mechanism 2501 can be separately provided, or the lower drive mechanism 2501 and the third drive mechanism can be shared, i.e., the lower drive mechanism 2501 is reused as the third drive mechanism. Specifically, for example, the lower drive mechanism 2501 includes a driver and a switching assembly connected to the driver. The switching assembly is capable of converting the power output of the driver into driving the brewing container 310 to move in the second direction and switching the first piston member 331 to move in the first direction. The driver is, for example, a motor. The switching assembly may include a nut directly or indirectly coaxially connected to the motor, a lead screw threadedly connected to the nut, and a sleeve sleeved around the lead screw. The sleeve is fixedly connected to the brewing container 310, and the lead screw is fixedly connected to the first piston member 331. One of the sleeve and the lead screw is provided with a guide groove extending in the second direction and the first direction, respectively, and the other is provided with a guide protrusion that slidably engages with the guide groove.

[0165] In addition, in view of the above, the arrangement scheme for the second cleaning member 500 is as follows:

[0166] First, similarly to the above, the second relative movement stroke can be formed by one of the first cleaning member 400 and the second cleaning member 500 being movable along the first direction, or by both the first cleaning member 400 and the second cleaning member 500 being movable along the first direction, and both being movable toward each other and away from each other. For ease of understanding, the following embodiments are described as an example in which the first cleaning member 400 is fixed relative to the base 100 and the second cleaning member 500 is movable relative to the base 100 along the first direction. In this case, the upper drive mechanism 2502 is drivingly connected to the second cleaning member 500.

[0167] Based on any of the above embodiments, the second cleaning member 500 can independently move in the first direction and is directly connected to the upper driving mechanism 2502. Alternatively, in one embodiment, the self-cleaning brewing system further includes a second piston member 332, which is disposed at the brewing position 120 and is movable in the second direction. During its movement, the second piston member 332 extends from the opening into the brewing chamber to compress the coffee powder in the brewing chamber. The second cleaning member 500 is fixedly disposed on a side of the second piston member 332 proximal to the first cleaning member 400, and the upper driving mechanism 2502 is drivingly connected to the second piston member 332. It will be appreciated that when the second piston member 332 moves in the first direction into the brewing container 310, it can compress the coffee powder dispersed in the brewing chamber to form a coffee cake, thereby helping to reduce the channel 211 effect during subsequent brewing, ensuring a more thorough brewing of the coffee powder. This also helps to increase brewing pressure and optimize the brewing effect. Since the movement paths of the second piston member 332 and the second cleaning member 500 are basically the same when the first cleaning member 400 is arranged adjacent to the brewing position 120, the second cleaning member 500 can be linked to the second piston member 332 so that the second piston member 332 can be driven to move by means of the upper driving mechanism 2502, and the second cleaning member 500 can be driven to move at the same time, which is equivalent to simplifying the setting of the driving mechanism of the second cleaning member 500, which helps to simplify the structure and reduce costs.

[0168] In practice, the outer shape of the second piston member 332 matches the shape of the inner cavity at a corresponding position of the brewing container 310. If the cross-section of the brewing container 310 is generally circular, the second piston member 332 is configured as a disc-shaped structure of the same shape. Similar to the lower drive mechanism 2501, the upper drive mechanism 2502 can be configured to include only a linear cylinder or a motor, a linear cylinder, a rotary cylinder, and other drives, as well as corresponding gear sets, rack and pinion systems, screw and nut mechanisms, and other transmission components, as needed. These components are not described in detail here.

[0169] In actual use, the second cleaning member 500 is disposed around the outer circumference of the second piston member 332. This ensures that, regardless of how the first cleaning member 400 is positioned relative to the brewing container 310, the second cleaning member 500 always has at least a portion in contact with the side surface of the first cleaning member 400, allowing it to scrape off dirt such as coffee grounds remaining on the side surface of the first cleaning member 400 during its movement in the first direction.

[0170] Specifically, when the outer dimensions of the second piston member 332 are substantially the same as the inner cavity dimensions at the corresponding position of the brewing container 310:

[0171] 16 and 17 , in one embodiment, the second cleaning member 500 can be offset to either side of the second piston member 332 in the first direction, for example, offset to an upper position of the second piston member 332, or offset to a lower position of the second piston member 332. In this way, while ensuring the functional effectiveness of the second cleaning member 500, the adverse effect of the second cleaning member 500 on the pressing operation of the second piston member 332 can be reduced.

[0172] Alternatively, in one embodiment, the second cleaning member 500 may still surround the outer circumference of the second piston member 332, but be movable relative to the second piston member 332 in the first direction. Thus, when the second piston member 332 drives the second cleaning member 500 to move closer to the first end surface of the cylinder body 311, the second cleaning member 500 first slides against the corresponding side surface of the first cleaning member 400 to clean the corresponding side surface of the first cleaning member 400. Then, when the second piston member 332 continues to move into the channel 211, it is stopped by the first end surface located around the end of the channel 211, and moves relative to the second piston member 332 in the first direction, so that only the second piston member 332 enters the channel 211 to complete the pressing operation, while the second cleaning member 500 is stopped outside the channel 211, thereby reducing the adverse effect of the second cleaning member 500 on the pressing operation of the second piston member 332.

[0173] The second piston member 332 is driven by the upper drive mechanism 2502. The second piston member 332 can also rotate while moving up and down. Thus, during the movement of the second piston member 332, the second cleaning member 500 can be synchronously driven to move up and down and rotate. The second cleaning member 700 is preferably arranged in a circular shape, or it can be arranged in a shape of multiple cleaning arms, with the angle between each cleaning arm being less than 120 degrees. The number of cleaning arms can be set to at least three arms.

[0174] Of course, when the outer dimensions of the second piston member 332 are slightly smaller than the inner dimensions of the brewing container 310 at a corresponding position, the second cleaning member 500 can be made of an elastic material and have elastic deformation capability in the second direction. Thus, when the second piston member 332 drives the second cleaning member 500 to move closer to the first end surface of the cylinder body 311, the second cleaning member 500 first slides against the corresponding side surface of the first cleaning member 400, completing the cleaning of the corresponding side surface of the first cleaning member 400. Then, when the second piston member 332 continues to move until it enters the channel 211, the second cleaning member 500 simultaneously enters the channel 211, but is squeezed by the inner wall of the channel 211 and undergoes compression deformation. This compression deformation helps to enhance the sealing strength between the second piston member 332 and the inner wall of the channel 211.

[0175] Based on any of the above embodiments, in a further embodiment, the second cleaning member 500 is no softer than the first cleaning member 400. Thus, when the second cleaning member 500 and the first cleaning member 400 engage in a second relative motion, the second cleaning member 500 elastically deforms to increase the sliding contact force with the first cleaning member 400, thereby enhancing the cleaning effect of the second cleaning member 500 on the first cleaning member 400. The first cleaning member 400 does not significantly deform, ensuring the structural integrity and accurate installation orientation of the first cleaning member 400, thereby maintaining its effective cleaning effect on the brewing container 310.

[0176] In addition, in a further solution, it can be arranged that in the process of approaching the brewing container 310 along the first direction, a gradually increasing interference amount is formed between the second cleaning member 500 and the first cleaning member 400, so that the cleaning effect of the second cleaning member 500 on the first cleaning member 400 is gradually enhanced, which is particularly suitable for the situation where the residue on the first cleaning member 400 is mainly accumulated in the lower area of ​​the first cleaning member 400.

[0177] To achieve the above purpose, the first cleaning member 400 and / or the second cleaning member 500 can be arranged such that their sliding contact surfaces gradually approach each other in a direction approaching the brewing container 310 along the first direction. Alternatively, the upper driving mechanism 2502 can be provided to drive the second cleaning member 500 to move along the above-mentioned inclined trajectory.

[0178] In specific applications, the first cleaning member 400 can be arranged in a plate shape, and the first cleaning member 400 is made of an elastic material, such as a rubber block or a rubber plate; and / or the second cleaning member 500 is configured as a brush body. At least the bristle portion of the second cleaning member 500 is made of a flexible material. When performing the second relative movement stroke, the bristles of the second cleaning member 500 face the adjacent side surface of the first cleaning member 400 and are in interference contact with the corresponding side surface of the first cleaning member 400. The bristle portion of the brush body can be made of a flexible material such as cloth, or can be further made of an elastic material such as a rubber strip. In this way, the bristle portion of the second cleaning member 500 can be deformed by being subjected to force, and while being in flexible contact with the corresponding side surface of the first cleaning member 400, it helps to increase the concave-convex adaptability with the corresponding side surface of the first cleaning member 400 through deformation, and increase the contact area with the corresponding side surface of the first cleaning member 400.

[0179] In addition, in one embodiment, the first cleaning member 400 is arranged adjacent to the brewing position 120, the first cleaning member 400 is adapted to the outer shape of the brewing container 310, and is extended along the circumference of the brewing container 310; the second cleaning member 500 is adapted to the shape of the adjacent side surface of the first cleaning member 400 and is extended.

[0180] The plane containing the area to be cleaned is the reference plane. In light of the above, the reference plane can be the plane containing the first end surface, or the plane containing the end surface of the first piston member 331 that movably extends from the first end surface. The first cleaning member 400 has an orthographic projection area on the reference plane. In a third direction perpendicular to the second direction, the orthographic projection area at least covers the area to be cleaned. In this way, when the first cleaning member 400 and the brewing container 310 are in relative motion, the first cleaning member 400 can clean the entire area to be cleaned at once.

[0181] Specifically, when the brewing container 310 is configured to be cylindrical, the first cleaning member 400 can be configured to extend in an arc shape along the circumference of the brewing container 310, with the length of the arc being no less than half the circumference of the brewing container 310. Alternatively, the first cleaning member 400 can be configured to extend in a straight line along the third direction, with the length of the straight line being no less than the maximum width of the brewing container 310 in the third direction. The shape of the second cleaning member 500 matches the shape of the adjacent side surface of the first cleaning member 400, and the extension length of the second cleaning member 500 in the third direction is no less than the corresponding length of the first cleaning member 400.

[0182] Referring to Figures 12 to 15 , a preferred embodiment of this novel use case includes the following: after the brewing container 310 finishes extracting coffee, the first piston 331 within the cylinder 311 pushes the coffee grounds upward and out of the cylinder 311. The brewing container 310 then rotates in a second direction, during which the first cleaning member 400 scrapes away the coffee powder. Once the brewing container 310 continues to rotate completely out of the brewing position 120 (not necessarily to the coffee powder receiving position 100), the second cleaning member 500 can begin operation to prevent coffee powder residue from the first cleaning member 400 from falling into the brewing container 310 and contaminating it.

[0183] Preferably, in the case of continuous brewing, when the brewing container 310 is moved to the powder receiving position 110, the upper driving mechanism 2502 drives the second piston 332 and the second cleaning member 500 to move in the first direction, moving downward to clean the first cleaning member 400. In order to ensure cleanliness, the number of up and down reciprocating movements of the second cleaning member 500 can be preset according to, for example, the degree of dirtiness of the first cleaning member 400, cleaning requirements, etc., and finally the second piston 332 is maintained near the stroke of the lower end of the second cleaning member 500. When the brewing container 310 moves to the brewing position 120, the second piston 332 continues to be pressed downward into the brewing container 310 to perform the lower brewing work, which reduces the movement stroke of the second piston 332, saves time, and improves the brewing efficiency. At the same time, when the brewing container 310 is located below the first cleaning member 400, the second cleaning member 500 is prevented from continuously scraping the first cleaning member 400 during the downward movement, causing dirt on the surface of the first cleaning member 300 to fall into the brewing container 310, thereby affecting the brewing quality and causing the quality of the extracted coffee liquid to deteriorate.

[0184] The present invention provides a beverage preparation device. The beverage preparation device includes a body and a brewing device provided on the body. It is understandable that the beverage preparation device can be, but is not limited to, electrical appliances such as coffee machines, soymilk machines, and grain wall breaking machines. Take the beverage preparation device as an example: when the beverage preparation device directly processes coffee powder, the brewing device is directly connected to external coffee powder, and extracts and brews the external coffee powder. The external powder can be, for example, coffee capsules, small cans of coffee powder, bagged coffee powder, etc. When the beverage preparation device directly processes coffee beans, the beverage preparation device can also include a grinding device, which is connected to coffee beans and grinds the coffee beans, or coffee powder of a desired coarseness; the discharge port of the grinding device is connected to the feed port of the brewing device, and the coffee powder obtained by the grinding device is connected to the brewing device for brewing to extract and brew the coffee powder.

[0185] Since the main invention of the present application is to improve the brewing device, the brewing device will be described mainly with reference to the accompanying drawings in the following embodiments.

[0186] 18 to 28 , the present invention provides a brewing device, which includes a brewing container 200 , a cleaning member 600 , and a driving mechanism. In which, the brewing container 200 forms an area to be cleaned; the cleaning member 600 includes a first cleaning unit 610 and a second cleaning unit 620, and at least one of the cleaning member 600 and the brewing container 200 is movably arranged relative to the other, so that the cleaning member 600 and the brewing container 200 have a relative movable stroke, and in the relative movable stroke, the first cleaning unit 610 and the second cleaning unit 620 both slide and abut against the area to be cleaned to remove dirt in the area to be cleaned; the driving mechanism is drivingly connected to the movably arranged cleaning member 600 and / or the brewing container 200; wherein, during the relative movable stroke, the cleaning member 600 has a proximal end close to the area to be cleaned and a distal end away from the area to be cleaned, the proximal end of the second cleaning unit 620 is arranged closer to the area to be cleaned than the proximal end of the first cleaning unit 610, and the softness of the second cleaning unit 620 is greater than the softness of the first cleaning unit 610.

[0187] In the technical solution provided by the present invention, under the drive of the driving mechanism, the cleaning member 600 and the brewing container 200 generate a relative motion stroke along a first direction. During this process, the first cleaning unit 610 and the second cleaning unit 620 both slide and abut against the area to be cleaned, and can provide at least two cleaning operations to the area to be cleaned in succession. Among them, because the second cleaning unit 620 contacts the area to be cleaned earlier than the first cleaning unit 610 and is softer, it can increase the contact area with the area to be cleaned and increase the surface fit with the area to be cleaned through elastic deformation during the first cleaning of the area to be cleaned, thereby helping to improve the comprehensiveness of cleaning the area to be cleaned; then, when the first cleaning unit 610 cleans the area to be cleaned for the second time, because the first cleaning unit 610 is less soft and has relatively greater rigidity, it can enhance the contact and abutment force between the cleaning unit and the area to be cleaned, thereby helping to improve the thoroughness of cleaning the area to be cleaned. This application helps to optimize the overall cleaning effect of the area to be cleaned of the brewing container 200.

[0188] In addition, in the present design, the brewing device may further include a base 100, which mainly provides a mounting carrier for functional components such as the brewing container 200, the cleaning member 600, and the driving mechanism. The base 100 may be, but is not limited to, one or more of a plate-like structure, a block-like structure, a box-like structure, and a frame structure. The base 100 may be a structure specially provided for the brewing device, and then when the brewing device is applied to the beverage preparation device, the base 100 is fixedly or movably installed with the body of the beverage preparation device. Of course, the base 100 may also be directly used for a fixed body such as the body of the beverage preparation device, which helps to integrate the above-mentioned brewing container 200, cleaning member 600, driving mechanism and other functional components of the brewing device on the body.

[0189] For ease of understanding, the following embodiments illustrate a brewing device placed horizontally on a platform, thus having a horizontal plane and a vertical direction. The horizontal plane includes a first direction and a second direction intersecting each other. However, it should be noted that the horizontal plane and the vertical direction do not limit the specific applications of the first and second directions. In other applications, the first and second directions may be directions other than the horizontal plane and the vertical direction. In the following embodiments, the first direction primarily refers to the relative movement direction between the cleaning element and the brewing container.

[0190] In view of the above, the brewing container 200 can be specifically arranged on the lower side of the base 100, and the aforementioned grinding device can be specifically arranged on the upper side of the base 100. In this way, the coffee powder ground by the grinding device can be added to the brewing container 200 by virtue of gravity. The brewing container 200 is suspended below the base 100, and the cleaning member 600 can be arranged between the base 100 and the brewing container 200, that is, located above the brewing container 200. Therefore, the near-far direction described in the following embodiments specifically refers to the up-down direction.

[0191] Next, the relative movement stroke can be formed by one of the cleaning member 600 and the brewing container 200 being movable along the first direction, or by both the cleaning member 600 and the brewing container 200 being movable along the first direction, and the two being movable toward each other and away from each other. For ease of understanding, the following embodiments are described as an example in which the cleaning member 600 is fixed relative to the base 100 and the brewing container 200 is movable relative to the base 100 along the first direction.

[0192] Specifically, as shown in FIG18 , the base 100 is plate-shaped and extends generally along a horizontal plane. The base 100 defines a powder receiving position 110 and a brewing position 120 spaced apart, corresponding to the movement path of the brewing container 200. The first direction is defined between the powder receiving position 110 and the brewing position 120. The drive mechanism includes a first drive mechanism 400, which drives the brewing container 200 to switch between the powder receiving position 110 and the brewing position 120. The first driving mechanism 400 can drive the brewing container 200 to perform linear translation between the powder receiving position 110 and the brewing position 120. At this time, the linear connection direction between the powder receiving position 110 and the brewing position 120 constitutes the first direction; of course, the first driving mechanism 400 can also drive the brewing container 200 to perform curved translation or rotational movement between the powder receiving position 110 and the brewing position 120. At this time, the curved connection direction between the powder receiving position 110 and the brewing position 120 constitutes the first direction.

[0193] The first drive mechanism 400 is specifically configured to suit the movement of the brewing container 200. When the brewing container 200 is moving linearly, the first drive mechanism 400 can be configured directly as a drive, such as a linear cylinder or motor, or a combination of a drive and a transmission assembly. The transmission assembly can include a gear set, a screw-nut mechanism, a pulley assembly, a rack-and-pinion assembly, and the like.

[0194] In view of this, the cleaning member 600 can be fixedly arranged on the moving path of the brewing container 200, that is, located on any side of the powder receiving position 110 and / or the brewing position 120 in the first direction, so that under the drive of the first driving mechanism 400, the brewing container 200 can move through the cleaning member 600 without additionally changing the moving path of the brewing container 200 or additionally setting up other driving mechanisms.

[0195] Furthermore, in one embodiment, the cleaning member 600 is fixedly disposed between the powder receiving position 110 and the brewing position 120. Thus, when the first drive mechanism 400 drives the brewing container 200 back and forth between the powder receiving position 110 and the brewing position 120, the cleaning member 600 can move past the cleaning member 600, eliminating the need to extend the travel path of the brewing container 200. Furthermore, when moving from the powder receiving position 110 to the brewing position 120, the cleaning member 600 can scrape any coffee powder that may remain in the area to be cleaned of the brewing container 200 and sweep it into the brewing chamber of the brewing container 200. When returning to the powder receiving position 110 via the brewing position 120, the cleaning member 600 can scrape away any coffee residue remaining in the area to be cleaned of the brewing container 200.

[0196] And / or in one embodiment, the cleaning member 600 is positioned closer to the brewing position 120 than to the coffee powder receiving position 110. Since hot water or hot milk is introduced into the brewing chamber of the brewing container 200 at the brewing position 120 to extract and brew the coffee powder, the temperature in the brewing chamber is relatively high and the remaining coffee grounds are in a softened state. At this time, by positioning the cleaning member 600 close to the brewing position 120, the softened coffee grounds can be cleaned immediately, avoiding cleaning the coffee grounds after they have cooled and hardened, which would increase the difficulty of cleaning the coffee grounds.

[0197] In view of the above, a brewing chamber for receiving coffee powder is formed within the brewing container 200. It is understood that the brewing container 200 can be configured as a semi-enclosed container having an inlet and an outlet. Alternatively, in one embodiment, the brewing container 200 includes a cylinder 311 and a first piston member 220. The cylinder 311 is provided with a channel 211 extending toward and away from the cleaning member 600 (i.e., in the vertical direction). The first piston member 220 is reciprocally movable within the channel 211 along its extension direction. The first piston member 220 is sealingly connected to the inner wall of the channel 211 to seal the lower section of the channel 211, thereby enclosing the aforementioned brewing chamber.

[0198] The first piston member 220 is provided with a plurality of water inlet holes, and the water inlet holes are used to connect external water to the channel 211. The external water may be, for example, hot water, hot milk, etc.

[0199] The second driving mechanism is disposed on the base 100 and is drivingly connected to the first piston 220 .

[0200] In a specific application, the end surface of the cylinder 311 near the cleaning member 600 is the first end surface, and the first end surface defines the area to be cleaned. In this way, the cleaning member 600 can remove coffee powder that has fallen on the first end surface, or coffee residue that has been discharged from the brewing chamber and retained on the first end surface. And / or when the first piston member 220 moves to extend out of the first end surface, the end surface of the first piston member 220 defines the area to be cleaned. When the brewing container 200 completes a single brewing and outputs the coffee beverage, the second drive mechanism can drive the first piston member 220 toward the first end surface, pushing out the coffee residue remaining on the inner wall of the channel 211 and accumulating it on the end surface and / or the first end surface of the first piston member 220 for removal by the cleaning member 600.

[0201] It is understood that the second drive mechanism and the first drive mechanism 400 can be provided separately, or the first drive mechanism 400 and the second drive mechanism can be shared, that is, the first drive mechanism 400 is reused for the second drive mechanism. Specifically, for example, the first drive mechanism 400 includes a driver and a switching assembly connected to the driver, and the switching assembly can convert the power output of the driver into driving the brewing container 200 to move in the first direction, and switch it to the first piston member 220 to move in the up and down direction. Wherein, the driver is, for example, a motor, and the switching assembly may include a nut directly or indirectly connected to the motor, a screw threadedly connected to the nut, and a sleeve sleeved on the outside of the screw, the sleeve being fixedly connected to the brewing container 200, and the screw being fixedly connected to the first piston member 220, and one of the sleeve and the screw being provided with a guide groove extending in the first direction and the up and down direction respectively, and the other being provided with a guide protrusion slidably connected to the guide groove.

[0202] In view of the above, regarding the arrangement of the cleaning member 600:

[0203] Referring to Figures 21 and 22, in one embodiment, the first cleaning unit 610 and the second cleaning unit 620 are arranged sequentially from far to near. That is, the first cleaning unit 610 is positioned directly above the second cleaning unit 620. Thus, during the relative movement, the second cleaning unit 620 first slides and abuts against the area to be cleaned, performing a first clean of the area to be cleaned. Because the second cleaning unit 620 is softer, it bends and deforms during its sliding contact with the area to be cleaned, causing the first cleaning unit 610 to then slide and abut against the area to be cleaned, performing a second clean of the area to be cleaned.

[0204] Alternatively, in one embodiment, the first cleaning unit 610 and the second cleaning unit 620 are sequentially arranged along a direction from the brewing position 120 to the powder receiving position 110. Thus, when the first driving mechanism 400 drives the brewing container 200 to switch between the powder receiving position 110 and the brewing position 120, the first cleaning unit 610 and the second cleaning unit 620 sequentially slide and abut against the area to be cleaned. Because the proximal end of the second cleaning unit 620 is positioned closer to the proximal end of the first cleaning unit 610 than to the area to be cleaned, the portion of the second cleaning unit 620 protruding from the first cleaning unit 610 allows the second cleaning unit 620 to deform under force.

[0205] In specific applications, the first cleaning unit 610 is plate-shaped and made of an elastic material, such as a rubber block or a rubber plate. During the relative movement, at least the proximal end surface of the first cleaning unit 610 slides and abuts against the area to be cleaned. That is, when the brewing container 200 moves past the cleaning member 600, the proximal end surface of the first cleaning unit 610 slides and abuts against the surface of the area to be cleaned; or when the brewing container 200 moves past the cleaning member 600, at least the proximal end surface of the first cleaning unit 610 slides and abuts against the surface of the area to be cleaned, that is, interference fit with the surface of the area to be cleaned, so that during the relative movement, at least the proximal end surface of the first cleaning unit 610 is deformed by force.

[0206] Furthermore, in one embodiment, the flexibility of the first cleaning element 610 increases from distal to proximal. This allows the proximal portion of the first cleaning element 610 to be more flexible and more easily elastically deformed, thereby flexibly contacting the surface of the area to be cleaned. This elastic deformation helps to increase the degree of conformity with the concave and convex portions of the surface to be cleaned, as well as the contact area with the surface to be cleaned. Furthermore, the distal end of the first cleaning element 610 can be made less flexible and more rigid, thereby providing sufficient structural strength for the entire first cleaning element 610 and preventing overall deformation and failure of the first cleaning element 610 due to insufficient rigidity.

[0207] It should be noted that the increase setting can be a linear continuous increase or a step-by-step increase.

[0208] There are several ways to achieve the softness change of the first cleaning unit 610:

[0209] In one embodiment, different flexibility can be achieved by differentiating the materials of the different plate segments of the first cleaning element 610 from distal to proximal. Specifically, the first cleaning element 610 may include a fixed plate segment 611 and a deformable plate segment 612, which are sequentially connected from distal to proximal. The fixed plate segment 611 and the deformable plate segment 612 are detachably connected. Various detachable connection methods are available, such as one or more of screwing, snap fastening, adhesive bonding, and suction fastening.

[0210] And / or in one embodiment, the different flexibility of the first cleaning element 610 can be achieved by configuring the first cleaning element 610 to have different plate segments from distal to proximal. Specifically, the thickness of at least the proximal segment of the first cleaning element 610 decreases from distal to proximal. By reducing the thickness of the proximal segment of the first cleaning element 610, the proximal segment of the first cleaning element 610 has greater flexibility than the distal end of the first cleaning element 610, making it more susceptible to deformation under stress.

[0211] Furthermore, in one embodiment, the second cleaning element 620 is configured as a brush body, with at least the bristles of the second cleaning element 620 being made of a flexible material. During the relative movement, the bristles of the second cleaning element 620 come into interference contact with the area to be cleaned. The bristles of the brush body can be made of a flexible material such as cloth, or further made of an elastic material such as a rubber strip. When the brewing container 200 moves past the cleaning member 600, at least the bristles of the second cleaning element 620 come into sliding contact with the surface of the area to be cleaned, i.e., into interference contact with the surface of the area to be cleaned. This causes at least the proximal portion of the second cleaning element 620 to deform under force during the relative movement. This allows the bristles of the second cleaning element 620 to deform under force, achieving flexible contact with the surface of the area to be cleaned. This deformation helps to increase the conformity to the surface of the area to be cleaned and the contact area with the surface of the area to be cleaned.

[0212] Furthermore, based on any of the above embodiments, in a further embodiment, the plane on which the area to be cleaned lies serves as a reference plane. In view of the above, the reference plane may be the plane on which the first end surface lies, or the plane on which the end surface of the first piston member 220 movably extends from the first end surface lies. The cleaning member 600 has an orthographic projection area on the reference plane, and along a second direction perpendicular to the first direction, the orthographic projection area at least covers the area to be cleaned. In this way, when the cleaning member 600 and the brewing container 200 are in relative motion, the cleaning member 600 can clean the entire area to be cleaned at once.

[0213] Specifically, when the brewing container 200 is configured to be cylindrical, the cleaning member 600 may be configured to extend in an arc shape along the circumference of the brewing container 200, and the length of the arc is not less than half the circumference of the brewing container 200. Alternatively, the cleaning member 600 may be configured to extend in a straight line along the second direction, and the length of the straight line is not less than the maximum width of the brewing container 200 in the second direction.

[0214] In specific application, referring to Figures 23 to 28 , when the brewing container 200 moves to the brewing position 120 and the coffee beverage is prepared and dispensed, the first piston member 220 moves vertically toward the location of the cleaning member 600, that is, toward the cylinder mouth of the cylinder body 311. During this movement, the coffee grounds 5 remaining on the inner wall of the channel 211 are scraped off and brought to the cylinder mouth of the cylinder body 311. At this time, the upper end surface of the first piston member 220 defines an area to be cleaned. The cleaning member 600 and the brewing container 200 then move relative to each other in a first direction, allowing the first cleaning member 610 and the second cleaning member 620 to clean the area to be cleaned respectively. During this movement, the coffee grounds 5 on the first piston member 220 are scraped off, effectively cleaning the coffee grounds 5 within the brewing container 200.

[0215] Furthermore, in one embodiment, the cleaning member 600 is rotatably mounted relative to the base 100. The distal end of the cleaning member 600 is rotatably connected to the base 200, thereby enabling the proximal end of the cleaning member 600 to tilt in a first direction. Consequently, when the brewing container 200 moves to the brewing position 120, and after the coffee beverage is prepared and dispensed, the first piston member 220 moves vertically toward the cleaning member 600, i.e., toward the opening of the cylinder 311. During this movement, the first piston member 220 scrapes away any coffee grounds 5 remaining on the inner wall of the passage 211 and moves the coffee grounds 5 toward the opening of the cylinder 311. At this point, the upper end surface of the first piston member 220 defines an area to be cleaned. The cleaning member 600 can then tilt toward the cylinder 311 and at least partially extend into the cylinder 311. As the cleaning member 600 continues to flip, it pushes the coffee grounds 5 out of the cylinder 311 , thereby helping to clean the inner wall of the cylinder 311 and the end surface of the first piston member 220 at the same time.

[0216] In addition, in another embodiment, when the brewing device further includes a pressing mechanism, the pressing mechanism is used to press the coffee powder in the brewing container 200 when the brewing container 200 moves to the brewing position 120, so that the coffee powder is pressed into a cake shape. Specifically, the pressing mechanism may include a second piston member movable in the up-down direction, and the second piston member may extend into the channel 211 to perform a powder pressing operation. Based on this, the cleaning member 600 may also include a third cleaning member located at the upper end of the first cleaning member 610, and the arrangement structure between the third cleaning member and the upper end of the first cleaning member 610 is substantially the same as the arrangement structure between the second cleaning member 620 and the lower end of the first cleaning member 610. In this way, when the lower ends of the second cleaning member 620 and the first cleaning member 610 jointly clean the coffee grounds 5 at the first piston member 220, the upper ends of the third cleaning member and the first cleaning member 610 can similarly clean the lower surface of the second piston member.

[0217] Referring to Figures 29 to 37 , the present invention provides a brewing module for a beverage preparation device, comprising a brewing device 320 and a first driving mechanism 320 . The brewing device 320 is provided with a feed inlet and a brewing chamber 211 for receiving and brewing powdered material. The powdered material enters the brewing chamber 211 through the feed inlet. The brewing device 320 is provided with a movable component that can propel the powdered material back and forth in a vertical direction, thereby evenly spreading the powdered material within the brewing chamber 211 during its vertical movement. The first driving mechanism 320 is drivingly connected to a movable portion of the brewing device 320 .

[0218] In other embodiments, the first driving mechanism may drive the brewing device to reciprocate relative to the movable part inside the brewing device, or the first driving mechanism may drive both to move simultaneously.

[0219] In the technical solution provided by the present invention, after the powder ground and discharged by the grinding device enters the brewing chamber 211 from the feed port, it is accumulated in the cavity of the brewing chamber 211 in the shape of a pointed cone; in the process of the brewing chamber 211 receiving the powder, and / or after the brewing chamber 211 completes the operation of receiving the required amount of powder, and / or before the pressing mechanism 330 performs the pressing operation on the powder, since the movable part can move up and down reciprocatingly, the powder located at the top of the pointed cone is accelerated to slide down during its vertical movement, so that the coffee powder tends to be evenly spread on the bottom cavity wall of the brewing chamber 211, forming a relatively flat surface to be pressed, which is more conducive to the subsequent balanced pressing of the pressing mechanism 330; at the same time, the coffee powder is also stably fixed on the bottom cavity wall of the brewing chamber 211, avoiding the occurrence of flying powder or falling powder, which helps to improve the pressing reliability of the subsequent pressing mechanism 330 as a whole, and ultimately optimizes the preparation quality of the coffee.

[0220] The beverage preparation machine in this design can be an intelligent, fully automatic or semi-automatic beverage device, such as a coffee machine or soymilk maker. Accordingly, the granular material referred to in this invention can be a legume material such as coffee beans or soybeans. For ease of understanding, the following embodiments are described using a coffee machine as an example, wherein the granular material refers to coffee beans and the powdered material refers to coffee powder.

[0221] It is understood that a beverage preparation machine generally includes a grinding device and a brewing device. The grinding device grinds and pierces the coffee beans using a tool such as a blade disc to obtain coffee powder. The brewing module in the brewing device receives the powder formed by the grinding device and evenly spreads the powder stacked in a pointed cone shape; the additional pre-set pressing mechanism 330 in the brewing device presses the powder stacked in the brewing chamber 211 into a cake; the additional pre-set liquid supply mechanism in the brewing device provides sufficient and required liquid (such as hot water) to the coffee powder pressed into the cake, ultimately achieving coffee extraction and brewing.

[0222] In view of the above, this design mainly improves the structure of the brewing module in the brewing device. The rest, such as the pressing mechanism 330 and the liquid supply mechanism, can refer to the existing technology and will not be described in detail in this design.

[0223] In this design, the brewing module used in the beverage preparation device may further include a base 100, which serves as a mounting base for the aforementioned brewing device and first drive mechanism. It is understood that the base 100 may be a plate-like structure, a block-like structure, a box-like structure, a frame-like structure, or other suitable structure for mounting, for example, the brewing device 320 and the first drive mechanism 320, specifically for the brewing module. Alternatively, the base 100 may be shared with a structure within the beverage preparation device (e.g., the housing) or with other components within the beverage preparation device (e.g., the grinding device), without limitation.

[0224] The base 100 defines a powder receiving position 110 and a brewing position 120, with the powder receiving position 110 and the brewing position 120 being spaced apart in the horizontal direction. The brewing device 320 is reciprocatably arranged between the powder receiving position 110 and the brewing position 120. The discharge port of the grinding device can be arranged above the powder receiving position 110, and the feed port of the brewing chamber 211 in the brewing device 320 can be arranged at the powder receiving position 110 or below the powder receiving position 110, so that the coffee powder obtained by the grinding device falls into the brewing chamber 211 under the action of gravity. The feed port in the brewing device 320 is generally arranged on the top wall of the brewing chamber 211, so that the coffee powder entering the brewing chamber 211 will naturally accumulate on the bottom wall of the brewing chamber 211, and present a pointed cone shape with a small cross-sectional area at the top and a large cross-sectional area at the bottom. The above-mentioned pressing mechanism 330 and liquid supply mechanism mainly act at the brewing position 120, so that when the brewing device 320 moves to the brewing position 120, the pressing mechanism 330 presses the coffee powder in the brewing device 320, so that the coffee powder is pressed into a cake; the liquid supply mechanism acts on the coffee powder in the brewing device 320, and extracts and brews the coffee powder in the brewing device 320.

[0225] Driven by the first driving mechanism 320, the movable part reciprocates in the vertical direction. On the one hand, during the vertical movement of the movable part, the coffee powder on the top of the cone-shaped bottom cavity wall of the brewing device 320 can be driven to slide down, thereby making the stacking area of ​​the coffee powder uniform and flat; on the other hand, the vertical movement of the movable part will not affect the accurate alignment between the feed port of the brewing cavity 211 and the discharge port of the grinding device, thereby reducing the loss of coffee powder during the receiving process and not occupying horizontal space.

[0226] In one embodiment, the brewing device 320 includes a brewing container 322 and a first piston member 331. The brewing container 322 has a material receiving channel extending vertically therethrough. The first piston member 331 is sealed within the material receiving channel and, together with the material receiving channel, defines the brewing chamber 211. The upper end surface of the first piston member 331 forms the bottom wall of the brewing chamber 211. The first piston member 331 is vertically reciprocable within the brewing chamber. The first piston member 331 constitutes the aforementioned movable component.

[0227] The brewing container 322 is generally in the shape of a hollow column extending in the vertical direction, with an open top to form a feed port; its lower end is also open to allow the first piston member 331 to extend into and reciprocate up and down in the material receiving channel. The outer shape of the first piston member 331 is adapted to the inner shape of the material receiving channel to reduce the installation gap formed therebetween. At least the outer periphery of the first piston member 331 is made of an elastic sealing material, or an elastic sealing ring layer is arranged on the outer periphery of the first piston member 331, so that the outer wall of the first piston member 331 is sealed against the inner wall of the material receiving channel, thereby achieving dynamic sealing during the vertical movement of the first piston member 331 relative to the brewing container 322, thereby preventing coffee powder or extracted coffee beverage from spilling out.

[0228] Before the brewing container 322 receives coffee powder, the first driving mechanism 320 drives the first piston 331 to move to a preset position within the coffee receiving passage. After the brewing container 322 receives coffee powder and before the pressing mechanism 330 compacts the coffee powder within the brewing container 322, the first driving mechanism 320 can drive the first piston 331 to reciprocate vertically at a preset speed for a preset number of times before stopping. During this process, the coffee powder is evenly spread across the bottom wall of the brewing chamber 211.

[0229] For ease of understanding, the vertical movable stroke of the first piston member 331 is specifically described below:

[0230] Referring to Figure 37, in one embodiment, the vertical travel of the first piston member 331 includes a first travel H1 within the brewing cylinder 211, where it cooperates with the pressing mechanism 330 to compress the powder for brewing. During this travel, the brewing device 320 is at the brewing position 120. The pressing component (e.g., another first piston member) in the pressing mechanism 330 moves vertically downward, while the first piston member 331 moves vertically upward, bringing the pressing component and the first piston member 331 closer together to press the powder into a cake. The entire vertical upward movement of the first piston member 331 constitutes the first travel H1.

[0231] Referring to Figures 34 to 36 , in one embodiment, the vertical movement of the first piston member 331 also includes a second stroke H2 for evenly spreading the powder within the brewing cylinder 211. During this stroke, the brewing device 320 can be in the brewing position 120. Before the pressing component moves vertically downward, the first piston member 331 can perform at least one vertical upward movement to evenly spread the powder accumulated on the first piston member 331. In this case, the entire vertical movement of the first piston member 331 constitutes the second stroke H2.

[0232] It can be understood that the first stroke H1 is used for compacting powder and requires a larger stroke volume, while the second stroke H2 is used for vibrating loose powder and its amplitude does not need to be set too large, that is, it requires a relatively smaller stroke volume. Therefore, in specific applications, the second stroke H2 can be set to be smaller than the first stroke H1.

[0233] Furthermore, in a specific application, if the speed of the first piston 331 during the first stroke H1 is defined as V1, and the speed of the first piston 331 during the second stroke H2 is defined as V2, where V1 is less than V2, then by appropriately increasing the speed V2 during the second stroke H2, the vibration frequency of the first piston 331 during the powder spreading process can be relatively higher, thereby achieving more efficient and uniform powder spreading.

[0234] A preferred embodiment is to rapidly raise the first piston 331 to a preset high position for powder shaking at a speed of V2, and then rapidly return to a preset low position for powder shaking at the same speed of V2, completing one powder shaking stroke. The second stroke H2 consists of at least one powder shaking stroke. In a specific application, the second stroke H2 can consist of, for example, two consecutive powder shaking strokes. The first piston 331 then pushes the powder upward at a speed of V1 to a powder compacting position, where it cooperates with the upper piston to compact the powder into a powder cake, wherein V1 is less than V2.

[0235] In one embodiment, the vertical travel of the first piston member 331 also includes a third travel H3 within the brewing cylinder 211 for pushing powder residue upward out of the brewing cylinder 211 after powder extraction, where H3 is greater than H1. During this travel, the brewing device 320 is at the brewing position 120. The pressing component moves vertically downward and the first piston member 331 moves vertically upward to compress the powder into a cake. After the liquid supply assembly completes the extraction and brewing of the powder cake and dispenses the coffee beverage, residue may remain on the inner wall of the brewing cylinder 211 and the upper surface of the first piston member 331. At this point, the first piston member 331 moves vertically upward to push the residue upward out of the brewing cylinder 211. The entire vertical upward movement of the first piston member 331 constitutes the third travel H3. At this time, the third stroke H3 is set to be greater than the first stroke H1 , so that the first piston 331 can fully move upward to at least partially extend out of the brewing cylinder 211 .

[0236] There are multiple solutions for the first driving mechanism 320 to achieve the above-mentioned purpose:

[0237] In one embodiment, the first drive mechanism 320 includes a first driver, which is disposed on the base 100 and has a telescopic output shaft that can reciprocate and extend in a vertical direction. The telescopic output shaft is connected to the first piston member 331. Specifically, the first driver is, for example, a linear cylinder, which can be integrally disposed below or beside the brewing container 322. When the linear cylinder is disposed beside the brewing container 322, the first drive mechanism 320 can also include a transmission member that can transmit the telescopic motion of the telescopic output shaft to the first piston member 331, thereby driving the vertical movement of the first piston member 331.

[0238] In addition, in another embodiment, the first driving mechanism 320 includes a driver 322, a driving rod 320 and a guide member 330. The driver 322 is provided on the base 100 and has a rotation output shaft rotatable along a vertical axis; the driving rod 320 is respectively installed on the base 100 rotatable along a vertical axis and translatably along a vertical direction, the driving rod 320 is connected to the rotation output shaft so as to be driven by the rotation output shaft to rotate along a vertical axis, and the driving rod 320 is connected to the first piston member 331; the guide member 330 is fixed relative to the brewing container 322 and connected to the driving rod 320, and the guide member 330 is fixed relative to the brewing container 322 and connected to the driving rod 320. One of the connections between the guide member 330 and the driving rod 320 is provided with a guide groove 321, and the other is provided with a guide protrusion that is slidably connected to the guide groove 321; wherein, the vertical movable stroke of the first piston member 331 includes a first stroke H1 in the brewing cylinder 211 for cooperating with the pressing mechanism 330 to press powder for brewing and extraction, a second stroke H2 in the brewing cylinder 211 for evenly spreading powder, and a third stroke H3 in the brewing cylinder 211 for pushing the powder residue upward out of the brewing cylinder 211 after the powder is extracted.

[0239] Specifically, the driver 322 is, for example, a motor, which can be arranged on the upper side, lower side or side of the brewing container 322. The rotation output shaft of the motor extends in the vertical direction so that it can rotate along its own axis when it starts running. The drive rod 320 also extends in the vertical direction and is directly or indirectly connected to the rotation output shaft so as to convert the rotation of the rotation output shaft into its own vertical movement in the vertical direction. The drive rod 320 and the first piston member 331 can also be directly or indirectly connected. The guide member 330 is fixed relative to the brewing container 322 so that when the guide protrusion slides along the guide groove 321 and is guided, it drives the drive rod 320 to move relative to the brewing container 322.

[0240] In one embodiment, the guide groove 321 includes a third groove section 321c extending in the vertical direction. This section converts the rotational motion of the drive rod 320 along the vertical axis into vertical translational motion of the first piston member 331 when the guide protrusion slides along the third groove section 321c. The first stroke H1, the second stroke H2, and the third stroke H3 are all formed by the vertical sliding stroke of the guide protrusion within the third groove section 321c. The third groove section 321c extends vertically and, as the guide protrusion slides along the third groove section 321c, converts the rotation of the drive rod 320 along the vertical axis into vertical translational motion, ultimately driving the vertical translation of the first piston member 331.

[0241] Specifically, in one embodiment, the third groove section 321c can be configured to extend helically in both the vertical direction and the circumferential direction of the drive rod 320, thereby converting the rotational motion of the drive rod 320 into vertical translational motion of the first piston member 331. Alternatively, in one embodiment, the first drive mechanism 320 further includes a driving gear 340 and a driven gear 350, wherein the driving gear 340 is coaxially mounted on the rotational output shaft; the driven gear 350 is disposed adjacent to the driving gear 340 and meshes with the driving gear 340; the driven gear 350 has an internal thread, and the drive rod 320 has an external thread, with the internal thread threadedly mating with the external thread. In this manner, by adjusting the gear ratio between the driving gear 340 and the driven gear 350, the rotational speed of the rotation from the rotational output shaft to the drive rod 320 can be reduced or accelerated accordingly. The arrangement of internal and external threads facilitates the combined motion of the drive rod 320, driven by the first driver, the driving gear 340, and the driven gear 350, in the form of rotational movement along the vertical axis and translational movement along the vertical axis, thereby converting the motion into helical translational movement of the drive rod 320. In this case, the third groove section 321c can be configured to extend substantially parallel to the axial direction of the drive rod 320, making it easier to process and shape.

[0242] Based on any of the above embodiments, further, referring to Figure 5, the guide groove 321 also includes a second groove section 321b extending along the circumference of the driving rod 320, and a first groove section 321a extending along the vertical direction, the second groove section 321b has a first end and a second end arranged opposite to each other in the circumference of the driving rod 320, the first end is connected to the third groove section 321c, and the second end is connected to the first groove section 321a, so that when the guide protrusion slides to the first end, the brewing container 322 is driven to be located at the brewing position 120, and when the guide protrusion is located at the second end, the brewing container 322 moves to the powder receiving position 110; another embodiment is that the first stroke H1, the second stroke H2 and the third stroke H3 are all formed by the stroke of the guide protrusion vertically sliding in the third groove section 321c.

[0243] Specifically, the guide groove 321 also includes an entry groove section 321e. It can be understood that, taking the guide groove 321 provided on the outer peripheral sidewall of the drive rod 320 as an example, the drive rod 320 includes a threaded rod section and a guide rod section connected sequentially from top to bottom. The threaded rod section is formed with external threads and threadedly engages with the internal threads of the driven gear 350. The guide groove 321 is provided on the guide rod section. The outer diameter of the guide rod section is larger than that of the threaded rod section, so that a step surface is formed at the connection between the guide rod section and the threaded rod section. The entry groove section 321e extends downward from the step surface to connect to the third groove section 321c or the second groove section 321b, so that the guide protrusion can slide into the entry groove section 321e from top to bottom and directly locate at the third groove section 321c, or move to the third groove section 321c via the second groove section 321b.

[0244] The entry slot section 321e is connected to the first end of the second slot section 321b. When the guide protrusion enters the entry slot section 321e and slides to the first end of the second slot section 321b, the brewing container 322 is in the brewing position 120. Furthermore, along the circumference of the drive rod 320, the second slot section 321b gradually extends obliquely toward one axial end of the drive rod 320, helping to slow down the rotation speed of the brewing container 322 when switching between the powder receiving position 110 and the brewing position 120, thereby ensuring smoother rotation of the brewing container 322.

[0245] When the guide protrusion moves in the third groove section 321c, the guide protrusion slides back and forth up and down in the third groove section 321c, which can drive the first piston member 331 to move vertically in the brewing chamber, performing the above-mentioned first stroke H1, second stroke H2 and third stroke H3 respectively.

[0246] Furthermore, in one embodiment, the guide groove 321 also includes a fourth groove section 321d, which extends circumferentially along the drive rod 320 and connects the first groove section 321a and the third groove section 321c at one end away from the second groove section 321b. The first groove section 321a, the second groove section 321b, the third groove section 321c, and the fourth groove section 321d substantially form an annular shape. Therefore, when the guide protrusion slides from the third groove section 321c along the fourth groove section 321d and finally to the first groove section 321a, the brewing container 322 returns from the brewing position 120 to the powder receiving position 110.

[0247] When the guide protrusion moves in the third groove section 321c, the brewing container 322 is in the brewing position 120, and the guide protrusion slides back and forth up and down in the third groove section 321c, which can drive the first piston member 331 to move vertically in the brewing chamber 211, adjust the position of the first piston member 331 in the brewing chamber 211, perform a pressing stroke, or push the coffee grounds in the brewing chamber 211 upward.

[0248] In view of the above, in one embodiment, the guide protrusion is fixedly arranged in the guide member 330, and the guide member 330 is fixedly arranged relative to the base 100. The driver 322 is used to drive the driving rod 320, driving the guide groove 321 of the driving rod 320 to slide along the guide protrusion. The guide protrusion moves from the first end of the second slot segment 321b along the third slot segment 321c to the fourth slot segment 321d until it moves to the connection between the fourth slot segment 321d and the first slot segment 321a. At this time, the driver 322 drives the driving rod 320 to rotate in the first rotation direction; when it moves from the connection between the fourth slot segment 321d and the first slot segment 321a to the second end of the second slot segment 321b, and further to the first end of 328b 321d and the first slot segment 321a, and in order to prevent the second slot segment 321b from reversing toward the second end of the second slot segment 321b when the driver 322 reverses direction at the first end of the second slot segment 321b and the connection between the fourth slot segment 321d and the first slot segment 321a, and the guide protrusion from moving in the opposite direction of the third slot segment 321c when the fourth slot segment 321d and the first slot segment 321a are located, a limiting portion is provided at the second slot segment 321b and the connection between the fourth slot segment 321d and the first slot segment 321a, so that at the above two position points, even if the driver 322 reverses rotation, it will not return along the original path.

[0249] The third groove section 321c is provided with a brewing position point in its stroke. When the guide protrusion is located at the brewing position point, the first piston member 331 and the second first piston member 332 are arranged in the brewing container 322 for extraction. When the third groove section 321c continues to move upward and the guide protrusion is located at the connection between the third groove point 328c and the fourth groove section 321d, the first piston member 331 pushes the extracted coffee grounds upward out of the brewing container 322.

[0250] In addition, in one embodiment, the driver 322 and the drive rod 320 are arranged on the side of the brewing container 322, which can reduce the space occupied by the driver 322 and the drive rod 320 in the vertical direction of the brewing container 322. At this time, the first driving mechanism 320 also includes a piston rod 360 and a linkage member 370. The piston rod 360 is fixedly connected to the first piston member 331 and is arranged side by side with the drive rod 320; the linkage member 370 links the drive rod 320 and the piston rod 360. The linkage member 370 can be a connecting rod extending in the horizontal direction, which is fixedly connected to the piston rod 360 and the drive rod 320 respectively, so as to accurately transmit the vertical movement of the drive rod 320 to the piston rod 360, drive the piston rod 360 to move vertically, and ultimately realize the driving of the vertical movement of the first piston member 331.

[0251] In addition, in one embodiment, the guide member 330 is cylindrical and movably sleeved on the outer side of the driving rod 320, and the outer side wall of the guide member 330 is ringed with an annular mounting groove; the brewing module used for the beverage preparation device also includes at least two connecting members 380 and a stop member 390, the connecting member 380 includes a first ring portion 381, a second ring portion 382 and a support portion 383 connecting the first ring portion 381 and the second ring portion 382, ​​the first ring portion 381 is fixedly sleeved on the outer side of the brewing container 322, and the second ring portion 382 is fixedly sleeved in the annular mounting groove, and each of the connecting members 380 is arranged in the annular mounting groove at intervals in the vertical direction; the stop member 390 is cylindrical and fixedly sleeved in the annular mounting groove, and a stop is provided between each of the connecting members 380 to jointly limit the connecting member 380 with the side groove wall of the annular mounting groove. The provision of at least two connectors 380 can increase the connection strength to the brewing container 322. The first ring portion 381 is adapted to secure the brewing container 322, while the second ring portion 382 is adapted to secure the guide member 330. The support portion 383 can separate the first ring portion 381 and the second ring portion 382, ​​thereby separating the brewing container 322 from the guide member 330 and preventing interference between the two. The provision of a stopper 390 can fill the gap between the connectors 380 and force each connector 380 to abut against the side walls of the annular mounting groove, thereby helping to secure each connector 380 to the guide member 330.

[0252] Furthermore, in one embodiment, the brewing container 322 is made of ceramic. Ceramic materials offer excellent rigidity and hardness, and are more wear-resistant, which helps extend the service life of the brewing container 322. Furthermore, ceramic materials offer excellent thermal insulation, which reduces heat exchange between the coffee beverage in the brewing chamber 211 and the surrounding environment during the extraction and brewing process, preventing the coffee beverage from cooling down and degrading its taste. In this embodiment, a user can input a desired number of cups of beverage to be prepared using a control panel, buttons, or the like. After obtaining the desired number of cups, the control device compares the desired number of cups with a preset number of cups. If the desired number of cups is not less than the preset number, the high-efficiency intelligent beverage device automatically activates the multi-brew mode. If the desired number of cups is less than the preset number, the high-efficiency intelligent beverage device automatically activates the single-brew mode, even if the user does not explicitly request a brewing mode. This improves brewing efficiency and makes the high-efficiency intelligent beverage device more intelligent.
