Detailed implementation mode

[0045] As described in the background art, a cleaning device is provided on the existing coffee machine, but this cleaning device needs to tilt the brewer and the brewing head respectively, resulting in low cleaning efficiency.

[0046] To solve the above problems, the present application provides a beverage equipment. Since the cleaning part is located between the piston part and the brewing assembly, cleaning liquid can be introduced into the cleaning part. When the cleaning liquid sprays upward, it can clean the brewing assembly, and when the cleaning liquid sprays downward, it can clean the piston part. In this way, the cleaning part can clean the piston part and the brewing assembly at the same time, which not only improves the cleaning efficiency, but also does not require a separate cleaning device for the piston part and the brewing assembly, reducing the occupation of space and saving costs.

[0047] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0048] See Figures 1 to 3, this application provides a beverage device 100, which may include a base 10, a brewing component 20, a brewing head component 30, and a cleaning component 40. The brewing component 20 is movably connected to the base 10. The brewing component 20 includes a brewer 21 and a piston member 22. The piston member 22 is slidably disposed within the brewer 21. The brewing head component 30 is connected to the base 10. The brewing head component 30 is located above the piston member 22 and is opposite to the piston member 22. The cleaning component 40 is movably connected to the base 10, and the cleaning component 40 is located between the piston member 22 and the brewing component 20. The cleaning component 40 is configured to clean the piston member 22 and the brewing head component 30 during the movement.

[0049] The brewing component 20 is movably connected to the base 10. The brewing component 20 is configured to receive beverage raw materials at a loading position and perform beverage extraction at an extraction position. Exemplarily, the brewing component 20 is movably connected to the base 10 in a first direction (x direction) such that the brewing component 20 can move relative to the base 10 along the first direction.

[0050] The brewing component 20 includes a brewer 21. When the brewing component 20 is at the loading position, the brewer 21 can be used to receive beverage raw materials; when the brewing component 20 is at the extraction position, beverage extraction can be performed within the brewer 21. Specifically, the beverage device 100 may include a cake-making component 60. The cake-making component 60 is located at the top of the loading position of the brewer 21. The cake-making component 60 is configured to move vertically (z direction) into the brewer 21 to form the beverage raw materials into a cake-shaped raw material 200 when the brewer 21 is at the loading position.

[0051] The brewing component 20 may further include a support structure 24. The brewer 21 is movably connected to the support structure 24 in the vertical direction (z direction). The support structure 24 is configured to maintain the opening of the brewer 21 facing upward and the vertical axis 212 of the brewer 21 parallel to the vertical direction (z direction) during the movement of the brewer 21 in the vertical direction (z direction). Exemplarily, the support structure 24 surrounds the outside of the brewer 21, and an accommodation space for accommodating the brewer 21 is provided inside the support structure 24.

[0052] By providing the support structure 24, a stable framework can be provided for the brewer 21, reducing mechanical wear caused by unnecessary movement or vibration, thereby improving the reliability and durability of the beverage device 100. By keeping the opening of the brewer 21 facing upward, the support structure 24 effectively prevents the spillage of beverage raw materials or liquid during the movement. This not only keeps the device clean but also ensures that the amount of beverage raw materials used for each extraction is accurate. The stability in the vertical direction (z direction) ensures that the water flow can evenly pass through the beverage raw material layer, thereby optimizing the extraction effect.

[0053] The brewing assembly 20 may further include a piston member 22. The piston member 22 is slidably disposed within the brewer 21, that is, the piston member 22 can move vertically (in the z-direction) within the brewer 21, and the top of the piston member 22 is used to carry the beverage raw materials to be extracted.

[0054] In addition, the piston member 22 may also be sealingly connected to the inner wall of the brewer 21. By providing the piston member 22 that is sealingly connected to the inner wall of the brewer 21, a sealed space can be provided for beverage extraction, reducing heat and pressure loss, helping to maintain the ideal extraction temperature and pressure, and improving the flavor and concentration of the beverage. The piston member 22 can ensure uniform distribution of the beverage raw materials within the brewer 21 and maintain a consistent pressure distribution during the extraction process. This uniformity helps to avoid channeling effects (i.e., uneven water flow through the beverage raw materials), thereby improving the uniformity and quality of extraction.

[0055] The brewing head assembly 30 is connected to the machine base 10, and the brewing head assembly 30 is located above the piston member 22 and opposite to the piston member 22. The brewing head assembly 30 performs beverage extraction through high-temperature and high-pressure water flow.

[0056] The cleaning member 40 is movably connected to the machine base 10, and the cleaning member 40 is located between the piston member 22 and the brewing assembly 20. The cleaning member 40 is used to clean the piston member 22 and the brewing head assembly 30 during the moving process.

[0057] In this embodiment, since the cleaning member 40 is located between the piston member 22 and the brewing assembly 20, a cleaning liquid can be introduced into the cleaning member 40. When the cleaning liquid is sprayed upward, it can clean the brewing assembly 20, and when the cleaning liquid is sprayed downward, it can clean the piston member 22. In this way, the cleaning member 40 can clean the piston member 22 and the brewing assembly 20 simultaneously, not only improving the cleaning efficiency, but also eliminating the need to configure a separate cleaning device for the piston member 22 and the brewing assembly 20 respectively, reducing space occupation and saving costs.

[0058] In addition, the spraying of the cleaning liquid from the cleaning member 40 to the piston member 22 and the spraying of the cleaning liquid to the brewing assembly 20 can be controlled separately. That is, the cleaning member 40 can also achieve cleaning of a single object, improving the working flexibility of the cleaning member 40.

[0059] In addition, since the cleaning member 40 is movably connected to the machine base 10, during the cleaning process, the cleaning member 40 can comprehensively clean the brewing assembly 20 and the piston member 22 by moving, improving the cleaning effect.

[0060] See Figure 4, in some embodiments, an accommodation cavity 411 is defined inside the cleaning member 40, and a plurality of liquid outlet holes 421 communicating with the accommodation cavity 411 are formed on the surface of the cleaning member 40. The accommodation cavity 411 is used to accommodate the cleaning liquid, and the cleaning liquid in the accommodation cavity 411 is ejected through the liquid outlet holes 421 to clean the piston member 22 and the brewing head assembly 30.

[0061] In some application scenarios, the cleaning liquid can be pre-stored in the accommodation cavity 411 in advance, and a power pump can be arranged in the accommodation cavity 411 to eject the pre-stored cleaning liquid from the liquid outlet holes 421.

[0062] In some other application scenarios, the cleaning member 40 can also connect the external cleaning liquid source to the accommodation cavity 411 through a pipeline, and use the power of the external cleaning liquid source to eject the cleaning liquid from the liquid outlet holes 421.

[0063] Furthermore, the cleaning liquid can be hot water, water vapor or a cleaning agent with cleaning ability. During cleaning, hot water or water vapor can be used to pre-wet and rinse the piston member 22 and the brewing head assembly 30 first, then the cleaning agent is used to clean the piston member 22 and the brewing head assembly 30, and finally hot water or water vapor is used to rinse the cleaning agent on the surface to achieve deep cleaning. Of course, if the pollution degree of the piston member 22 and the brewing head assembly 30 is relatively light, only hot water and water vapor can be used to simply rinse and disinfect the piston member 22 and the brewing head assembly 30.

[0064] In some specific embodiments, the cleaning member 40 can be a separate component. The accommodation cavity 411 is formed inside the component, and the liquid outlet holes 421 are arranged on the surface of the component and communicate with the accommodation cavity 411.

[0065] In some other specific embodiments, the cleaning member 40 can also be formed by combination. Refer to Figure 4 , the cleaning member 40 can include a movable arm 41 and a cleaning sleeve 42. The movable arm 41 is movably connected to the machine base 10. The movable arm 41 has an accommodation cavity 411 for accommodating the cleaning liquid. The cleaning sleeve 42 is sleeved on the movable arm 41. The cleaning sleeve 42 is provided with liquid outlet holes 421 communicating with the accommodation cavity 411. The cleaning liquid in the accommodation cavity 411 is ejected through the liquid outlet holes 421 to clean the piston member 22 and the brewing head assembly 30.

[0066] In this embodiment, the movable arm 41 can be made of a rigid material (such as plastic or metal) to obtain strong mechanical strength. The movable arm 41 is movably connected to the machine base 10 so that the whole cleaning member 40 can move relative to the piston member 22 or the brewing assembly 20 to spray the cleaning liquid on both of them comprehensively.

[0067] The interior of the movable arm 41 has a receiving cavity 411, which can be open. After the cleaning sleeve 42 is sleeved on the movable arm 41, the opening of the receiving cavity 411 can be sealed, and the liquid outlet holes 421 on the surface of the cleaning sleeve 42 are communicated with the receiving cavity 411.

[0068] In some specific embodiments, the movable arm 41 can also be set to be strip-shaped, and the receiving cavity 411 is also shaped into a strip accordingly. The cleaning sleeve 42 is set to be strip-shaped, and the liquid outlet holes 421 are arranged at intervals along the length direction of the cleaning sleeve 42 to form multiple rows of liquid outlet holes 421. Among the multiple rows of liquid outlet holes 421, a part is arranged on the circumferential part of the movable arm 41 facing the piston member 22, and the other part is arranged on the circumferential part of the movable arm 41 facing the brewing head assembly 30.

[0069] In some specific embodiments, the cleaning sleeve 42 can also be made of flexible materials, such as sponge sleeves, rubber sleeves, soft plastic sleeves, soft rubber sleeves, etc. On the one hand, this facilitates the installation of the cleaning sleeve 42 on the movable arm 41. On the other hand, when the cleaning sleeve 42 contacts the piston member 22 and the brewing assembly 20 during the movement of the movable arm 41, it can avoid scratching the surfaces of the piston member 22 and the brewing assembly 20.

[0070] See Figures 5 to 7 , in some embodiments, the cleaning member 40 can also include a first cleaning portion 46, which is arranged on the outer surface of the cleaning sleeve 42. When the cleaning member 40 is moving, the first cleaning portion 46 is used to clean the stains on the piston member 22 and / or the brewing head assembly 30.

[0071] In this embodiment, the first cleaning portion 46 is arranged on the outer surface of the cleaning sleeve 42, and the first cleaning portion 46 can be set with a cleaning direction facing the piston member 22 and / or the brewing head assembly 30. In this way, when the cleaning member 40 is moving, the first cleaning portion 46 moves with the cleaning member 40 and contacts the piston member 22 and / or the brewing head assembly 30 to physically clean the stains thereon, which is convenient for cooperating with the cleaning liquid to deeply clean the piston member 22 and / or the brewing head assembly 30.

[0072] In some specific embodiments, the cleaning sleeve 42 has a first installation groove 431 along its length direction, and the first cleaning portion 46 has a first installation portion 461 that cooperates with the first installation groove 431. In this way, the first cleaning portion 46 can be installed in a quick-release manner through the first installation groove 431 and the first installation portion 461, which is convenient for replacement.

[0073] See Figures 5 to 7, in some embodiments, the cleaning member 40 may further include a second cleaning portion 47 disposed on the outer surface of the cleaning sleeve 42. When the cleaning member 40 is in motion, the second cleaning portion 47 is used to clean the stains on the piston member 22 and / or the brewing head assembly 30.

[0074] Similarly, the second cleaning portion 47 is disposed on the outer surface of the cleaning sleeve 42. When the cleaning member 40 is in motion, the second cleaning portion 47 moves with the cleaning member 40 and contacts the piston member 22 and / or the brewing head assembly 30 to physically clean the stains thereon, thus facilitating the deep cleaning of the piston member 22 and / or the brewing head in cooperation with the cleaning liquid.

[0075] In some specific embodiments, the cleaning sleeve 42 has a second installation groove 432 along its length direction, and the second cleaning portion 47 has a second installation portion 471 that cooperates with the second installation groove 432. In this way, the second cleaning portion 47 can be quickly installed through the cooperation of the second installation groove 432 and the second installation portion 471, which is convenient for replacement.

[0076] The types of the second cleaning portion 47 and the first cleaning portion 46 can be set differently. In some exemplary embodiments, the first cleaning portion 46 can be set as a soft rubber strip, and the second cleaning portion 47 can be set as bristles. Such a matching method can enrich the cleaning function of the cleaning sleeve 42 and clean more types of stains. For example, the bristles can sweep away powdery residues, and the soft rubber strip can scrape off wet residues attached to the surface.

[0077] It should be noted that in the present application, the first cleaning portion 46 and the second cleaning portion 47 can be used alternatively or jointly. However, whether the first cleaning portion 46 and the second cleaning portion 47 are used alternatively or jointly, the number of the first cleaning portion 46 and the second cleaning portion 47 is not limited. That is to say, the number of the first cleaning portion 46 and the second cleaning portion 47 can be set to one or more according to the actual situation.

[0078] It should also be noted that in actual use, the forms of the first cleaning portion 46 and the second cleaning portion 47 are not limited to the bristles and soft rubber strips in the above examples, and can be flexibly replaced according to the actual situation, such as a scraper.

[0079] See Figures 5 to 7 , in some embodiments, the cleaning member 40 may further include a first cleaning portion 46 and a second cleaning portion 47. The first cleaning portion 46 is disposed on the outer surface of the cleaning sleeve 42. The second cleaning portion 47 is disposed on the outer surface of the cleaning sleeve 42 and is circumferentially spaced from the first cleaning portion 46 around the cleaning sleeve 42. The cleaning member 40 is configured to rotate the cleaning sleeve 42 circumferentially to drive the first cleaning portion 46 and the second cleaning portion 47 to rotate, thereby adjusting the positions of the first cleaning portion 46 and the second cleaning portion 47.

[0080] In this embodiment, since the first cleaning part 46 and the second cleaning part 47 are arranged on the outer surface of the cleaning sleeve 42 and the cleaning sleeve 42 rotates circumferentially, the positions of the first cleaning part 46 and the second cleaning part 47 can be adjusted. With such an arrangement, appropriate cleaning tools can be selected according to the soiling conditions of the object to be cleaned actually.

[0081] For example, when the piston part 22 needs to be rinsed, the cleaning sleeve 42 can be rotated first to make the brush bristles face the piston part 22 for powder sweeping, and then hot water or steam can be used for flushing, resulting in a better cleaning effect.

[0082] For another example, when the brewing head assembly 30 needs to be rinsed, the cleaning sleeve 42 can be rotated first to make the soft rubber strip face the brewing head assembly 30 for stain scraping, then the cleaning sleeve 42 can be rotated to make the brush bristles face the brewing head assembly 30 for powder sweeping, and finally hot water or steam can be used for flushing, resulting in a better cleaning effect.

[0083] See Figure 6 , in some exemplary embodiments, the movable arm 41 has a socket part 414 and a fixing part 412. The socket part 414 is used for socketing with the cleaning sleeve 42 to form a receiving cavity 411, and the fixing part 412 is connected to the connecting shaft so as to connect to the machine base 10. The socket part 414 is also circumferentially rotatably connected to the fixing part 412. Since the socket part 414 is socketed with the cleaning sleeve 42, when the socket part 414 rotates circumferentially, the cleaning sleeve 42 can be driven to rotate, and further the cleaning sleeve 42 can be made to drive the first cleaning part 46 and the second cleaning part 47 to rotate.

[0084] Furthermore, the rotation mode of the socket part 414 (cleaning sleeve 42) can be either manually driven or achieved by motor driving. This application does not make a special limitation on this.

[0085] See Figures 5 to 12 , in some exemplary embodiments, the movable arm 41 can be connected to the machine base 10 in a rotatable manner. Specifically, the first end of the movable arm 41 is rotatably connected to the machine base 10, and the second end is a free end. Since the first end of the movable arm 41 is a pivot end and has a relatively small relative displacement during rotation, a joint can be arranged at the first end of the movable arm 41 or a position close to the first end to be connected to the external cleaning liquid source through a pipeline. In this way, the influence on the pipeline during the rotation of the movable arm 41 is reduced.

[0086] See Figure 6 , Figure 11 , Figure 12 and Figure 13, the cleaning member 40 may further include a connecting shaft 43. One end of the connecting shaft 43 is connected to the movable arm 41, and the other end is movably connected to the machine base 10. A liquid guiding hole 431 is provided inside the connecting shaft 43. One end of the liquid guiding hole 431 is communicated with the accommodating cavity 411, and the other end is used to be connected to a cleaning liquid source. The cleaning liquid enters the accommodating cavity 411 through the liquid guiding hole 431.

[0087] In this embodiment, the movable arm 41 is rotatably connected to the machine base 10 through the connecting shaft 43. A liquid guiding hole 431 communicated with the accommodating cavity 411 is provided inside the connecting shaft 43. During use, the cleaning liquid source can be communicated with the liquid guiding hole 431 of the connecting shaft 43 through a connector. In this way, the cleaning liquid is sprayed out successively through the liquid guiding hole 431, the accommodating cavity 411 and the liquid outlet hole 421 to clean the piston member 22 and the brewing head assembly 30.

[0088] In this embodiment, since the connector for connecting the cleaning liquid source can also be arranged at the pivoting end of the movable arm 41, there is no displacement during the rotation of the movable arm 41, reducing the influence on the pipeline.

[0089] Of course, on the premise of ensuring safety, in other embodiments, the connector for connecting the cleaning liquid source can also be arranged at other positions of the movable arm 41 or on other components connected to the movable arm 41.

[0090] See Figure 7 and Figure 13 , in some embodiments, the outer shape cross-section of the cleaning sleeve 42 is a polygonal structure. At least one edge of the polygonal structure abuts against the piston member 22, and at least another edge of the polygonal structure abuts against the brewing head assembly 30. With such a setting, it is convenient to scrape off residues during the movable cleaning of the movable arm 41. And since the polygonal structure of the cleaning sleeve 42 has inclined surfaces, the scraped-off residues can be received and adsorbed by these inclined surfaces, improving the cleaning effect and the collection effect. Further, the liquid outlet holes 421 are opened on the surface of the polygonal structure. There are multiple surfaces of the polygonal structure, and the angles of each surface are different. The liquid outlet holes 421 facing the piston member 22 can be arranged on adjacent surfaces with different angles, so as to realize multi-angle spraying of the cleaning liquid and multi-angle cleaning of the piston member 22. Similarly, the liquid outlet holes 421 facing the brewing head assembly 30 can be arranged on adjacent surfaces with different angles, so as to realize multi-angle spraying of the cleaning liquid and multi-angle cleaning of the brewing head assembly 30.

[0091] Further, the outer shape cross-section of the cleaning sleeve 42 is in the shape of a regular hexagon, a regular octagon, etc.

[0092] In some embodiments, the number of the liquid outlet holes 421 is multiple, and the multiple liquid outlet holes 421 are spaced apart along the length direction of the cleaning sleeve 42.

[0093] In some embodiments, the shape of the liquid outlet hole 421 includes at least one of a circle, a rectangle, and a triangle.

[0094] See Figure 5 , Figures 10 to 12 , in some embodiments, the beverage device 100 may further include a first driving member 44 and a first transmission assembly 45. The first driving member 44 is connected to the base 10, one end of the first transmission assembly 45 is connected to the first driving member 44, and the other end is connected to the cleaning member 40. The first driving member 44 drives the cleaning member 40 to move through the first transmission assembly 45.

[0095] In this embodiment, the first driving member 44 may be a driving motor. The driving motor is fixed on the base 10. One end of the first transmission assembly 45 is in transmission connection with the output shaft of the driving motor, and the other end is in transmission connection with the cleaning member 40. When the driving motor is started, the output shaft of the driving motor transmits power to the cleaning member 40 through the first transmission assembly 45 to prompt the cleaning member 40 to move. During the movement of the cleaning member 40, it dynamically scrapes and sprays the cleaning liquid onto the target object to clean the piston member 22 and the brewing assembly 20.

[0096] In some specific embodiments, the cleaning member 40 is rotatably connected to the base 10, and the rotation area of the cleaning member 40 can cover the piston member 22 and the brewing head assembly 30. That is to say, the cleaning member 40 scrapes and sprays the cleaning liquid onto the target object by rotating to clean the piston member 22 and the brewing assembly 20.

[0097] In some exemplary embodiments, the rotation axis of the cleaning member 40 may be provided at one end of the cleaning member 40. In this way, the cleaning member 40 can rotate in a manner similar to a swing, forming a fan-shaped rotation area. The brewing head assembly 30 can be covered above the fan-shaped rotation area, and the piston member 22 can be covered below. In this way, the cleaning member 40 can be used to clean the brewing head assembly 30 and the piston member 22 simultaneously and comprehensively.

[0098] In some exemplary embodiments, the rotation axis of the cleaning member 40 may be provided in the middle of the cleaning member 40. In this way, when the cleaning member 40 completes a full rotation, the cleaning member 40 can form a circular rotation area (the radius of the rotation area is the distance from the rotation axis to the farther end). The brewing head assembly 30 can be covered above the circular rotation area, and the piston member 22 can be covered below. In this way, the cleaning member 40 can be used to clean the brewing head assembly 30 and the piston member 22 simultaneously and comprehensively.

[0099] Of course, the cleaning member 40 can also be set to rotate less than one week to form a fan-shaped rotation area, so that the fan-shaped rotation area covers the piston member 22 and the brewing head assembly 30, and the above technical effects can also be achieved.

[0100] In some further embodiments, when the cleaning member 40 cleans the target by rotation, the first transmission member is correspondingly configured to transmit the rotational force to transmit the rotational force of the driving motor to the cleaning member 40.

[0101] See Figure 5 , Figures 10 to 12 , specifically, the first transmission assembly 45 may further include a first transmission gear 451 and a second transmission gear 452. The first transmission gear 451 is connected to the first driving member 44, the second transmission gear 452 is meshed with the first transmission gear 451, and the second transmission gear 452 is connected to the cleaning member 40.

[0102] Further, the first transmission gear 451 may be fixedly sleeved on the output shaft of the driving motor, and the second transmission gear 452 may be fixedly sleeved on the connecting shaft 43 of the cleaning member 40. Further, the transmission ratio of the first transmission gear 451 to the second transmission gear 452 is set to be greater than, so as to achieve a deceleration effect and make the rotation of the cleaning member 40 more stable.

[0103] See Figure 14 , in some specific embodiments, the cleaning member 40 is movably connected to the machine base 10, and the rotation area of the cleaning member 40 can cover the piston member 22 and the brewing head assembly 30. That is to say, the cleaning member 40 scrapes and sprays the cleaning liquid onto the target object by moving, so as to clean the piston member 22 and the brewing assembly 20.

[0104] In some exemplary embodiments, since the brewing head assembly 30 is located above the piston member 22 and opposite to the piston member 22. The cleaning member 40 is located between the piston member 22 and the brewing assembly 20. The cleaning member 40 can move from one side to the other side. During the movement, a moving area is formed. The brewing head assembly 30 can be covered above the moving area, and the piston member 22 can be covered below, so that the cleaning member 40 can be used to clean the brewing head assembly 30 and the piston member 22 simultaneously and comprehensively.

[0105] In some further embodiments, when the cleaning member 40 cleans the target by moving, the first transmission assembly 45 not only needs to transmit the power of the driving motor to the cleaning member 40, but also needs to convert the rotational force of the driving motor into a linear motion.

[0106] In an exemplary embodiment, the first transmission assembly 45 may be a gear-rack structure. The gear is fixedly arranged on the output shaft of the driving motor, the rack is fixed on the cleaning member 40, the gear is meshed with the rack, and when the driving motor rotates, the gear drives the rack to move linearly, and the rack drives the cleaning member 40 to move linearly.

[0107] Of course, the method of converting the power of the drive motor from rotation to linear motion is not limited to the above examples. For example, the first transmission component 45 can also be configured as a worm and worm gear structure, a lead screw structure, etc., which will not be listed one by one here.

[0108] In addition, when the cleaning part 40 performs cleaning by moving, the first driving part 44 can also be directly configured as a device for outputting linear power, such as a power cylinder, etc., so that the first transmission component 45 can be omitted.

[0109] See Figure 2 、 Figure 3 and Figure 15 In some embodiments, the brewing assembly 20 can move relative to the machine base 10 between a loading position and an extraction position. When the brewing assembly 20 is in the loading position, it is used to receive the beverage raw materials. When the brewing assembly 20 is in the extraction position, it is used for beverage extraction.

[0110] Furthermore, the cleaning part 40 is used to clean the piston part 22 and the brewing head assembly 30 when the brewing assembly 20 is in the extraction position.

[0111] In use, the brewing assembly 20 receives the beverage raw materials at the loading position and forms the beverage raw materials into a cake-shaped raw material 200. After completing this process, the brewing assembly 20 moves to the extraction position for beverage extraction to obtain the beverage liquid. During the extraction process, the brewer 21 drives the piston part 22 to move upward along the vertical direction and connects with the brewing head assembly 30 located above, so that the brewing head assembly 30 provides a high-temperature extraction liquid to the brewer 21 to achieve extraction. After completing the extraction, the brewer 21 moves downward to reset and separates from the brewing assembly 20.

[0112] That is to say, after completing the extraction process, the brewing assembly 20 and the brewing head assembly 30 are in opposite positions. At this time, the cleaning part 40 can be used to clean both the piston part 22 of the brewing assembly and the brewing head assembly 30 simultaneously, improving the cleaning efficiency. In addition, since when the brewing assembly 20 is in the extraction position, the extraction process has just ended, at this time the beverage is relatively warm and soft, making it easy to remove.

[0113] See Figure 2 、 Figure 3 and Figure 15 In some embodiments, the beverage device 100 may include a second driving part 26 and a second transmission component 27. One end of the second transmission component 27 is connected to the second driving part 26, and the other end is connected to the brewing assembly 20. The second driving part 26 drives the brewing assembly 20 to move relative to the machine base 10 through the second transmission component 27.

[0114] In the embodiment of the present application, the second driving member 26 may be a driving motor. The driving motor is fixed on the machine base 10. One end of the second transmission assembly 27 is in transmission connection with the output shaft of the driving motor, and the other end is in transmission connection with the brewing assembly 20. After the driving motor is started, the output shaft of the driving motor transmits power to the brewing assembly 20 through the second transmission assembly 27 to prompt the brewing assembly 20 to move, so that the brewing assembly 20 moves between the loading position and the extraction position.

[0115] Further, the second transmission assembly 27 may further include a third transmission gear 271 and a transmission rack 272. One end of the third transmission gear 271 is connected to the brewing assembly 20, and the other end is connected to the second driving member 26. The transmission rack 272 is connected to the machine base 10 and extends along the moving direction of the brewing assembly 20. The third transmission gear 271 meshes with the transmission rack 272. The second driving member 26 drives the brewing assembly 20 to move through the cooperation of the third transmission gear 271 and the transmission rack 272.

[0116] After the driving motor is started, the output shaft of the driving motor drives the third transmission gear 271 to rotate. The third transmission gear 271 drives the transmission rack 272 to move linearly. The transmission rack 272 drives the brewing assembly 20 to move linearly, so that the brewing assembly 20 moves between the loading position and the extraction position.

[0117] Of course, in other embodiments, the second transmission assembly 27 may also be other structures. For example, the second transmission member may also be arranged in a worm and worm gear structure, a lead screw structure, etc., which will not be listed one by one here.

[0118] In addition, when the brewing assembly 20 is cleaned by moving, the second driving member 26 may also be directly set as a device for outputting linear power, such as a power cylinder, etc., so that the second transmission assembly 27 can be omitted.

[0119] In some embodiments, when the cleaning member 40 cleans the piston member 22, the surface of the piston member 22 protrudes from the brewer 21.

[0120] In use, the brewing assembly 20 receives the beverage raw materials at the loading position and forms the beverage raw materials into a cake-shaped raw material 200. After this process is completed, the brewing assembly 20 moves to the extraction position for beverage extraction to obtain the beverage liquid. During the extraction process, the brewer 21 drives the piston member 22 to move upward along the vertical direction and is connected to the brewing head assembly 30 located above, so that the brewing head assembly 30 provides a high-temperature extraction liquid to the brewer 21 to achieve extraction. After the extraction is completed, the brewer 21 moves downward to reset and separates from the brewing assembly 20. The piston member 22 remains stationary, that is, the piston member 22 protrudes from the brewer 21, so that the slag on the piston member 22 exposes the brewer 21, which is convenient for the cleaning member 40 to clean.

[0121] See Figures 16 to 19 The piston member 22 is hermetically connected to the inner wall of the brewer 21, and the piston member 22 is movably connected to the brewer 21 in the vertical direction (z-direction). The top of the piston member 22 is used to carry the beverage raw material to be extracted. When the brewer 21 moves upward in the vertical direction (z-direction), it drives the piston member 22 to move upward in the vertical direction (z-direction).

[0122] In a possible implementation, the piston member 22 moves up and down through a driving assembly. The driving assembly includes a driving motor (not shown in the figure), a transmission member 282, and a guide rail 284. The transmission member 282 is disposed on the brewing assembly 20. The guide rail 284 is fixedly connected to the brewer 21, and the guide rail 284 extends in the vertical direction (z-direction). Wherein, when the brewing assembly 20 moves to the extraction position, the transmission member 282 is in transmission connection with the guide rail 284, and the transmission member 282 is used to drive the guide rail 284 to move in the vertical direction (z-direction) when rotating.

[0123] In a possible implementation, the brewing assembly 20 may include a trigger rod 23. The trigger rod 23 may include a first connecting portion 231 and a second connecting portion 232 spaced apart in the first direction (x-direction). The first connecting portion 231 is rotatably connected to the piston member 22. The support structure 24 is provided with a third connecting portion 241 that cooperates with the second connecting portion 232. The second connecting portion 232 is rotatably connected to the third connecting portion 241.

[0124] The first connecting portion 231 may be rotatably connected to the piston member 22, and the first connecting portion 231 is movably connected to the piston member 22. For example, the first connecting portion 231 may be a chute structure disposed along the x-direction, and the piston member 22 is provided with a fixing portion, and the fixing portion is disposed in the chute structure and can move in the chute structure. So that when the piston member 22 moves upward along the z-direction following the brewer 21, it can drive the end where the first connecting portion 231 is located to move upward.

[0125] The support structure 24 is further provided with a locking structure 50. A part of the locking structure 50 is located between the first connecting portion 231 and the second connecting portion 232. The locking structure 50 is used to be in locking connection with the trigger rod 23 when the brewer 21 drives the piston member 22 to move upward in the vertical direction (z-direction). At this time, the top surface of the piston member 22 is flush with or higher than the top surface of the support structure 24.

[0126] With such arrangement, when the piston member 22 moves upward along the vertical direction (z direction) following the brewer 21, the first connection portion 231 of the trigger rod 23 can be driven to move upward along the vertical direction (z direction) following the piston member 22. Since the second connection portion 232 of the trigger rod 23 is rotatably connected to the third connection portion 241 of the support structure 24, and the support structure 24 does not move in the vertical direction (z direction), one end of the first connection portion 231 of the trigger rod 23 can be tilted, and then the piston member 22 can be locked to the outside of the support structure 24 through the locking structure 50, so that the piston member 22 can locate the extracted residue on the top of the piston member 22, which is convenient for cleaning the residue and convenient for using the cleaning member to clean the top surface of the piston member 22 to ensure the effect of the next extraction.

[0127] In one possible implementation, the locking structure 50 may include an elastic tenon 51, which is movably connected to the support structure 24 in a second direction (y direction), and the second direction (y direction) is perpendicular to both the vertical direction (z direction) and the first direction (x direction).

[0128] Exemplarily, the elastic tenon 51 can be extended and retracted in the second direction (y direction) relative to the support structure 24. When the trigger member squeezes the elastic tenon 51, the elastic tenon 51 can be squeezed to a retracted state, so that the trigger rod 23 and the elastic tenon 51 can be switched from an unlocked state to a locked state, or from a locked state to an unlocked state.

[0129] With such a configuration, the elastic tenon 51 can be extended and retracted in the second direction (y direction) relative to the support structure 24, thereby forming an elastic locking structure 50, and the locking connection can be released when the piston member 22 needs to be released. Such an elastic tenon 51 has a relatively simple structure and principle, which can reduce the difficulty of assembly and processing cost, thereby reducing the cost of the beverage device 100.

[0130] When in use, the brewer 21 drives the piston 22 to move upward in the vertical direction, and then the beverage is extracted. When the beverage is extracted, the brewer 21 moves downward in the vertical direction to the position before the rise, that is, the brewer 21 is moved into the support structure 24, but the piston 22 is still located at the top, that is, located outside the brewer 21 due to the locking effect of the trigger member and the locking structure 50.

[0131] The trigger rod 23 may include an extension portion 234. In the first direction (x direction), the extension portion 234 is located at an end of the trigger rod 23 away from the first connection portion 231. The extension portion 234 extends upward along the vertical direction (z direction), and when the first connection portion 231 moves upward along the vertical direction (z direction), the extension portion 234 moves along the first direction (x direction) toward the loading position.

[0132] In a possible implementation, the machine base 10 may include a resisting portion 11. The resisting portion 11 is configured to drive the unlocking of the locking structure 50 and the trigger rod 23 when the brewing assembly 20 moves in a direction close to the loading position, and to drive the extension portion 234 to move in a direction close to the extraction position, and drive the piston member 22 to move downward in the vertical direction (z direction) through the first connecting portion 231.

[0133] The resisting portion 11 is disposed on a side of the loading position of the machine base 10 away from the extraction position, and the resisting portion 11 extends in the x direction toward the extraction position. The locking structure 50 includes a ejector rod 52. When the locking structure 50 locks the trigger rod 23, the ejector rod 52 extends from a side of the support structure 24 away from the loading position to the outside of the support structure 24.

[0134] When the brewing assembly 20 moves from the extraction position to a specific position in the direction of the loading position, the resisting portion 11 abuts against the ejector rod 52. When the brewing assembly 20 continues to move toward the loading position, the resisting portion 11 drives the ejector rod 52 to move in a direction close to the extraction position, thereby unlocking the locking connection between the locking structure 50 and the trigger rod 23.

[0135] While unlocking the locking connection between the locking structure 50 and the trigger rod 23, during the process that the brewing assembly 20 continues to move toward the loading position, the resisting portion 11 abuts against the extension portion 234 of the trigger rod 23, and as the brewing assembly 20 moves, gradually drives the extension portion 234 to move in a direction close to the extraction position, thereby causing the end where the first connecting portion 231 of the trigger rod 23 is located to drive the piston member 22 to move downward.

[0136] By providing the resisting portion 11, during the process that the brewer 21 moves from the extraction position to the loading position in the first direction (x direction), the locking structure 50 can be automatically driven to unlock the locking connection with the trigger rod 23, and automatically drive-connected (e.g., abutted) with the extension portion 234. As the brewing assembly 20 gradually moves toward the loading position in the first direction (x direction), the extension portion 234 is driven to move in a direction close to the extraction position, thereby driving the first connecting portion 231 to move downward in the vertical direction (z direction), and then pulling the piston member 22 back to the initial position through the first connecting portion 231 for the next extraction. Throughout the process, unlocking and driving are achieved through a mechanical structure, and no additional motor is required to drive the piston member 22, which can simplify the structure of the beverage device 100 and reduce costs.

[0137] In a possible implementation, as Figure 19As shown, a blocking portion 12 is provided on the machine base 10. In the vertical direction (z-direction), the blocking portion 12 is located in the upper space of the support structure 24. The blocking portion 12 is used to push against the extracted cake-shaped raw material 200 during the movement of the brewing assembly 20 from the extraction position to the loading position, so as to separate the extracted cake-shaped raw material 200 from the piston member 22. During the pushing process between the blocking portion 12 and the extracted cake-shaped raw material 200, the piston member 22 is always located at the second position. At this time, the top surface of the piston member 22 is flush with or higher than the top surface of the support structure 24. Since the extracted cake-shaped raw material 200 is provided on the top surface of the piston member 22, it is convenient to clean the extracted cake-shaped raw material 200 and the like after the piston member 22 stays outside the support structure 24.

[0138] By providing the blocking portion 12 on the machine base 10, during the movement of the brewing assembly 20 from the extraction position to the loading position along the first direction (x-direction) after the extraction of the brewing assembly 20 is completed, it can push against the residue of the extracted cake-shaped raw material 200 on the top surface of the piston member 22. During the movement of the brewing assembly 20, the extracted cake-shaped raw material 200 is gradually separated from the top surface of the piston member 22. By setting the piston member 22 to always be located at the second position during the pushing process between the blocking portion 12 and the extracted cake-shaped raw material 200, it can be ensured that the top surface of the piston member 22 is flush with or higher than the top surface of the support structure 24, so as to ensure that all the extracted cake-shaped raw material 200 is located on top of or above the support structure 24, so as to separate all the extracted cake-shaped raw material 200 from the piston member 22, ensure the cleanliness of the piston member 22, and ensure the consistency of multiple extractions.
