Technical Field

[0001] This application relates to the field of beverage preparation technology, and in particular to a beverage preparation structure and a beverage preparation device. Background Technology

[0002] With the advancement of technology and social development, people's demands for quality of life are also increasing, and coffee, as a beverage made from roasted and ground coffee beans, is one of the most popular drinks on the market today. Fully automatic coffee machines, which automatically grind, tamp, brew, and remove coffee grounds, allow users to easily obtain various coffee drinks by simply selecting their preferred coffee beans. Therefore, they have gained widespread popularity.

[0003] However, due to structural defects, existing fully automatic coffee machines sometimes have coffee grounds splashing onto the side walls of the grounds container and the inside of the machine during the cleaning process. These residual grounds are difficult to clean and can easily breed bacteria, thus posing a health risk to users. Summary of the Invention

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0071] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0072] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0074] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0075] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0076] See Figure 1 One embodiment of this application provides a beverage preparation apparatus for grinding plant seeds, fruits, and other materials into powder and then brewing them to obtain a beverage.

[0077] The following description uses a fully automatic coffee machine for processing coffee beans as an example to illustrate the construction of the beverage preparation structure 100 in this application. This embodiment is only used as an example and does not limit the technical scope of this application. It is understood that in other embodiments, the beverage preparation device may also be other devices equipped with the beverage preparation structure 100, which are not limited here.

[0078] The beverage preparation structure 100 includes a mounting bracket 10 and a feeding assembly 20, a receiving cylinder assembly 30, a pressing cylinder assembly 40, and a pushing member 50, all respectively mounted on the mounting bracket 10. The feeding assembly 20 grinds coffee beans to produce coffee powder and conveys the coffee powder to the receiving cylinder assembly 30. The pressing cylinder assembly 40 presses the coffee powder in the receiving cylinder assembly 30 into a coffee cake 200, and water at a certain temperature and pressure can be introduced into the pressing cylinder assembly 40, allowing the water to penetrate the coffee cake 200 to generate coffee liquid. The pushing member 50 scrapes away the used coffee cake 200, allowing the receiving cylinder assembly 30 to receive coffee powder again from the feeding assembly 20. In some embodiments, the beverage preparation structure 100 also includes a residue box (not shown), located at the bottom of the mounting bracket 10, where the coffee cake 200 scraped away by the pushing member 50 falls and is collected.

[0079] Furthermore, the beverage preparation structure 100 also includes a guiding component (not shown) and a driving component 70. The mounting bracket 10 has a connecting groove 16. The guiding component is located on one side of the mounting bracket 10, and the receiving cylinder assembly 30 is movably limited within the connecting groove 16 and can be engaged with the guiding component. The driving component 70 is located on one side of the mounting bracket 10 and is drively connected to the receiving cylinder assembly 30. Driven by the driving component 70, the receiving cylinder assembly 30 can move under the guidance of the connecting groove 16 and the guiding component, switching between a receiving state for receiving coffee powder, a pressing state for pressing the coffee caddy 200, and a pushing state for scraping the coffee caddy 200.

[0080] In the beverage preparation structure 100 described above, the receiving cylinder assembly 30 is moved by the drive assembly 70. Under the guidance of the connecting groove 16 and the guide assembly, the three actions of receiving, pressing and pushing can be realized. This is different from the prior art in which the powder cake 200 is scraped off by the movement of the powder scraper. This can prevent the surface of the powder cake 200 in contact with the powder scraper from exerting a certain force on the powder cake 200 when the powder scraper scrapes the powder, which would cause the powder to adhere to the machine body. This makes it easier to clean the beverage preparation structure 100 and the beverage preparation device equipped with it. At the same time, it simplifies the construction of the drive structure, reduces the number of parts, and reduces the production cost of the beverage preparation structure 100.

[0081] like Figure 1 and Figure 2As shown, the mounting bracket 10 has an approximately "L"-shaped flat plate structure, and the length direction of the mounting bracket 10 is defined as the first direction (i.e., Figure 1 The X direction in the middle), the height direction of the mounting bracket 10 is the second direction (i.e., Figure 1 The thickness direction of the mounting bracket 10 is a third direction (Y direction in the diagram). The first direction, the second direction, and the third direction are perpendicular to each other, and the second direction is parallel to the vertical direction. The mounting bracket 10 includes a first mounting part 12 and a second mounting part 14. The second mounting part 14 is connected to one side of the first mounting part 12 in the first direction, and the height of the second mounting part 14 in the second direction is greater than the height of the first mounting part 12 in the first direction. It is understood that the shape of the mounting bracket 10 is not limited to this and can be configured as needed to meet different installation and fixing requirements.

[0082] Furthermore, the connecting groove 16 extends through two opposite surfaces of the mounting bracket 10 along the thickness direction of the mounting bracket 10. The connecting groove 16 is approximately "V" shaped and includes a first connecting segment 16a and a second connecting segment 16b connected to the first connecting segment 16a. The first connecting segment 16a is formed in the first mounting portion 12 and extends obliquely upward from the end of the first mounting portion 12 away from the second mounting portion 14 toward the second mounting portion 14 until it connects to the second connecting segment 16b. The second connecting segment 16b is formed in the second mounting portion 14 and extends obliquely upward from the first connecting segment 16a, and the slope of the second connecting segment 16b is greater than the slope of the first connecting segment 16a.

[0083] Thus, the drive assembly 70 is located on the third-party upward side of the mounting bracket 10, and the guide assembly is located on the other side of the mounting bracket 10 facing away from the drive assembly 70 in the third-party upward direction. The receiving cylinder assembly 30 is mounted above the first mounting portion 12 of the mounting bracket 10, near the end of the second connecting section 16b of the connecting groove 16 away from the first connecting section 16a. The pressing cylinder assembly 40 is mounted on the second mounting portion 14 of the mounting bracket 10 and located on the side of the mounting bracket 10 where the guide assembly is located in the third-party upward direction, near the end of the second connecting section 16b of the connecting groove 16 away from the first connecting section 16a. The pusher 50 is located on the side of the pressing cylinder assembly 40 away from the first mounting portion 12.

[0084] Please combine Figure 1 , Figure 3 as well as Figure 4As shown, in some embodiments, the drive assembly 70 includes a drive member 72, a lead screw 74, a connecting rod 76, and a first connecting unit 78. The drive member 72 is mounted on the third-party upward side of the mounting bracket 10. The lead screw 74 is drivenly connected to the drive member 72 and is correspondingly arranged in the third-party upward direction to the second connecting section 16b of the connecting groove 16. The extension direction of the lead screw 74 is parallel to the second connecting section 16b of the connecting groove 16. The connecting rod 76 is located on the third-party upward side of the mounting bracket 10 opposite to the drive member 72. The connecting rod 76 has an elongated structure. One end of the connecting rod 76 is connected to the lead screw 74 through the first connecting unit 78 and can reciprocate along the lead screw 74. The other end of the connecting rod 76 is connected to the receiving cylinder assembly 30. The first connecting unit 78 includes a nut 781, a first fastener 873, and a washer 785. The washer 785 is located on the side of the bracket facing away from the lead screw 74. One end of the nut 781 is engaged with the lead screw 74, and the other end of the nut 781 is inserted into the connecting rod 76. The first fastener 873 can be a screw. One end of the first fastener 873 passes through the washer 785 and is fixed to the nut 781, thereby allowing one end of the connecting rod 76 to be movably connected to the lead screw 74.

[0085] Thus, the drive unit 72 can controllably drive the lead screw 74 to rotate. The rotation of the lead screw 74 causes the first connecting unit 78 to move along the axial direction of the lead screw 74. The movement of the lead screw 74 drives one end of the connecting rod 76 to move, and the connecting rod 76 in turn drives the receiving cylinder assembly 30 to move along the connecting groove 16.

[0086] like Figure 1 , Figure 3 as well as Figure 5 As shown, in some embodiments, the receiving cylinder assembly 30 includes a base 31, a second connecting unit 32, a receiving cylinder 33, a piston 34, and a reset member 35. The base 31 is drively connected to the drive assembly 70 and includes a bottom wall and side walls extending from opposite sides of the bottom wall. The base and the two side walls together form a receiving space for accommodating the receiving cylinder 33. The bottom wall of the base 31 is rotatably connected to one end of the connecting rod 76 via the second connecting unit 32. The second connecting unit 32 includes a hinge 321 and a second fastener 323. One end of the hinge 321 abuts against the surface of the mounting bracket 10 facing the lead screw 74 in a third direction. The other end of the hinge 321 passes sequentially through the connecting groove 16 and the bracket of the mounting bracket 10 and is fixed to the bottom wall of the base 31 via the second fastener 323. Thus, one end of the hinge 321 is confined in the connecting groove 16 and can move and rotate within the connecting groove 16, thereby rotatably connecting the receiving cylinder assembly 30 to the connecting rod 76.

[0087] The receiving cylinder 33 is housed within the receiving space and clamped between the two side walls of the base 31. The receiving cylinder 33 has a hollow cylindrical structure, including a closed end and an open end arranged opposite each other in the axial direction, and the central axis of the receiving cylinder 33 is perpendicular to a third direction. The piston 34 has a columnar structure, and one end of the piston 34 extends into the receiving cylinder 33 through the closed end along the axial direction of the receiving cylinder 33.

[0088] The mounting bracket 10 has a supporting edge 18 extending longitudinally along its edge at the top in a third-direction upward direction. When the pressing cylinder assembly 40 is in the pushing state, one end of the piston 34 extending out of the receiving cylinder 33 abuts against the supporting edge 18, thereby pushing the powder cake 200 inside the receiving cylinder 33 out of the receiving cylinder 33. The reset member 35 is sleeved outside the piston 34, with one end abutting against the receiving cylinder 33 and the other end of the reset member 35 limited to the end of the piston 34 extending out of the receiving cylinder 33. The reset member 35 is used to apply a force to the piston 34 away from the open end of the receiving cylinder 33, so that the reset member 35 returns to its initial position after the powder cake 200 is pushed out.

[0089] Furthermore, the receiving cylinder assembly 30 also includes a first positioning member 36 and a second positioning member 37. One end of the first positioning member 36 and the second positioning member 37 is mounted on the bottom wall of the base 31 and located on opposite sides of the second connecting unit 32. The other end of the first positioning member 36 and the second positioning member 37 extends out of the bottom wall of the base 31. The receiving cylinder assembly 30 is engaged with the guide assembly through the first positioning member 36 and the second positioning member 37. As a preferred embodiment, the receiving cylinder assembly 30 also includes two elastic members 38. The first positioning member 36 and the second positioning member 37 are floatingly mounted on the base 31 through the elastic members 38, thereby allowing the length of the first positioning member 36 and the second positioning member 37 extending out of the base 31 to be adjusted within a certain range.

[0090] Thus, the receiving cylinder assembly 30 achieves three-point positioning through the second connecting unit 32, the first positioning member 36, and the second positioning member 37. The central axes of the second connecting unit 32, the first positioning member 36, and the second positioning member 37 are connected sequentially to form an isosceles triangle. Since the positional relationship of the second connecting unit 32, the first positioning member 36, and the second positioning member 37 remains fixed, the position of the second connecting unit 32 changes due to the movement of the receiving cylinder assembly 30 along the connecting groove 16. The positions of the first positioning member 36 and the second positioning member 37 also change accordingly under the guidance of the guiding component. This allows the receiving cylinder assembly 30 to rotate while moving along the connecting groove 16, thereby switching between different states.

[0091] like Figure 1 , Figure 2 , Figure 7 as well as Figure 8As shown, in some specific embodiments, the guiding component includes a first guide rail 61, a second guide rail 63, and a third guide rail 65. The first guide rail 61 and the second guide rail 63 are located on opposite sides of the connecting groove 16 in the width direction of the connecting groove 16, and the first guide rail 61 corresponds to one side of the second connecting segment 16b disposed in the connecting groove 16. The third guide rail 65 is spaced apart at the end of the first connecting segment 16a of the connecting groove 16 away from the second connecting segment 16b. The first positioning member 36 of the receiving cylinder assembly 30 can be positioned on the first guide rail 61 or the third guide rail 65 and move along the first guide rail 61 or the third guide rail 65, and the second positioning member 37 can be positioned on the second guide rail 63 and move along the second guide rail 63.

[0092] More specifically, the first guide rail 61 includes a first guide groove 611, a second guide groove 612, and a third guide groove 613. The first guide groove 611 is disposed parallel to one side of the second connecting segment 16b of the connecting groove 16. The second guide groove 612 is connected to the side of the first guide groove 611 away from the connecting groove 16, and the extension direction of the second guide groove 612 is perpendicular to the first guide groove 611. The third guide groove 613 is disposed parallel to the side of the first guide groove 611 close to the connecting groove 16. The first guide groove 611, the second guide groove 612, and the third guide groove 613 have an intersection point, through which they are interconnected.

[0093] Furthermore, the first guide rail 61 also has a first steering portion 614 and a second steering portion 615. The first steering portion 614 protrudes from the first guide groove 611 and is located near the intersection of the first guide groove 611 and the second guide groove 612. The first steering portion 614 is used to guide the first positioning member 36 from the first guide groove 611 to the second guide groove 612. The second steering portion 615 protrudes from the first guide groove 611 and is located at the intersection of the first guide groove 611 and the third guide groove 613. The second steering portion 615 is used to block the first positioning member 36 from moving from the first guide groove 611 to the third guide groove 613, thereby restricting the movement path of the first positioning member 36.

[0094] The second guide rail 63 has a fourth guide groove 632 and a fifth guide groove 634. The fourth guide groove 632 is arranged parallel to one side of the connecting groove 16. The shape of the fourth guide groove 632 is similar to that of the connecting groove 16 and is roughly "V" shaped. The fifth guide groove 634 is located on the side of the fourth guide groove 632 near the connecting groove 16 and at the end of the second guide rail 63 near the third guide rail 65. The extension direction of the fifth guide groove 634 is parallel to the second connecting section 16b of the connecting groove 16, and the ends of the fourth guide groove 632 and the fifth guide groove 634 near the third guide rail 65 are connected to each other.

[0095] The third guide rail 65 is provided with a sixth guide groove 652, the extension direction of which is parallel to the first connecting segment 16a of the connecting groove 16.

[0096] In some embodiments, the pusher 50 is located at one end of the second guide rail 63 near the pressing cylinder assembly 40, so that when the receiving cylinder assembly 30 moves along the second guide rail 63, the pusher 50 can scrape off the powder cake 200 at one end of the receiving cylinder assembly 30.

[0097] In some embodiments, the beverage preparation structure 100 further includes multiple triggers (not shown), which are mounted on the mounting bracket 10. The triggers can be micro switches, photoelectric sensors, etc. When the receiving cylinder assembly 30 is in the receiving state, pressing state, or pushing state, the base 31 of the receiving cylinder assembly 30 abuts against the corresponding trigger and sends a position signal, thereby achieving precise control of the workflow of the beverage preparation structure 100.

[0098] The working principle of the beverage preparation structure 100 described above is as follows:

[0099] like Figure 1 and Figure 9 As shown, when the receiving cylinder assembly 30 is in the receiving state, the receiving cylinder assembly 30 is located on one side of the feeding assembly 20, and the open end of the receiving cylinder 33 faces the feeding assembly 20 to receive materials. At this time, the first positioning member 36 of the receiving cylinder assembly 30 is limited to the sixth guide groove 652 of the third guide rail 65, and the second positioning member 37 is limited to the fourth guide groove 632 of the second guide rail 63.

[0100] like Figure 6 and Figure 9 As shown, when the receiving cylinder assembly 30 switches from the receiving state to the pressing state, the drive assembly 70 drives the receiving cylinder assembly 30 to move along the connecting groove 16 toward the pressing cylinder assembly 40. At this time, the first positioning member 36 disengages from the sixth guide groove 652 of the third guide rail 65 and enters the first guide groove 611 of the first guide rail 61 and moves along the first guide groove 611, while the second positioning member 37 moves along the fourth guide groove 632.

[0101] When the receiving cylinder assembly 30 is in the pressing state, the receiving cylinder assembly 30 is located at the end of the connecting groove 16 near the pressing cylinder assembly 40, and the open end of the receiving cylinder 33 faces the pressing cylinder assembly 40. The pressing cylinder assembly 40 extends into the receiving cylinder 33 and engages with the receiving cylinder 33, thereby realizing the actions of pressing, injecting water, and generating coffee liquid. At this time, the first positioning member 36 is limited to the first guide groove 611, and the second positioning member 37 is limited to the fourth guide groove 632.

[0102] like Figure 7 , Figure 8 , Figure 10 as well as Figure 11As shown, when the receiving cylinder assembly 30 switches from the pressing state to the pushing state, the drive assembly 70 drives the receiving cylinder assembly 30 to move along the connecting groove 16 in a direction away from the pressing cylinder assembly 40. At this time, the first positioning member 36 first moves along the first guide groove 611 of the first guide rail 61, and then turns into the second guide groove 612 due to the obstruction of the first turning part 614. The drive assembly 70 continues to drive the receiving cylinder assembly 30 to move, the first positioning member 36 leaves the second guide groove 612 and enters the third guide groove 613 through the second turning part 615, and the second positioning member 37 disengages from the fourth guide groove 632. During this process, the receiving cylinder 33 rotates around the second connecting unit 32 as the rotation center, and finally the open end of the receiving cylinder 33 faces the side where the pushing member 50 is located.

[0103] When the receiving cylinder assembly 30 is in the pushing state, the drive assembly 70 drives the receiving cylinder assembly 30 to move along the connecting groove 16 toward the pressing cylinder assembly 40. At this time, the first positioning member 36 moves along the third guide groove 613, and the second positioning member 37 is located outside the second guide rail 63. During this process, one end of the piston 34 pushes the powder cake 200 out of the receiving cylinder 33 under the support of the supporting edge 18 of the mounting bracket 10. The powder cake 200 that extends out of the receiving cylinder 33 is scraped off by the powder scraper. The scraped powder cake 200 can fall freely under the action of gravity and fall into the powder residue box at the bottom of the beverage preparation structure 100.

[0104] like Figure 12 and Figure 13 As shown, when the receiving cylinder assembly 30 switches from the pushing state to the receiving state, the drive assembly 70 drives the receiving cylinder assembly 30 to move along the connecting groove 16 toward the side where the feeding assembly 20 is located. At this time, the first positioning member 36 first moves along the third guide groove 613, then moves away from the third guide groove 613, and finally returns to the sixth guide groove 652 of the third guide rail 65. The second positioning member 37 enters the fifth guide groove 634 and moves along the fifth guide groove 634 before finally entering the fourth guide groove 632. During the above movement, when the first positioning member 36 enters the sixth guide groove 652 from the third guide groove 613, the second positioning member 37 is engaged in the fifth guide groove 634, so the receiving cylinder assembly 30 rotates and the open end of the receiving cylinder 33 is re-aligned with the feeding assembly 20.

[0105] The beverage preparation structure 100 and beverage preparation device described above prepare beverages by driving the receiving cylinder assembly 30 to move relative to the feeding assembly 20, the pressing cylinder assembly, and the pushing component 50 through the driving assembly 70. After use, the powder cake 200 is collected by free fall, which simplifies the construction of the beverage preparation structure 100, reduces the number of parts, improves the reliability of transmission, effectively prevents coffee powder residue, and facilitates the cleaning of the beverage preparation device.

[0106] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0107] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
