Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and in particular to a coffee spout, a coffee dispensing structure, and a coffee machine. Background Technology

[0002] Coffee machines generally include a grinding structure, a brewing structure, and a dispensing structure. The brewed coffee flows out from the dispensing port of the dispensing structure and can be used directly. For example, Chinese invention patent application number CN202011064679.2 (publication number CN112244647B) discloses a coffee machine including a housing, a grinder, a brewer, a dispensing component, a waste container, a drip tray, and a control system. The housing has a front door and a feeding port on the top wall. The grinder is located inside the housing and grinds coffee beans into coffee powder. The brewer compresses the coffee powder into a cake and brews it to produce coffee liquid. The dispensing component is connected inside the housing and extends out of the housing through the front door, connecting to the coffee liquid outlet of the brewer.

[0003] Currently, the coffee spout in the dispensing unit is prone to overflow (i.e., the coffee spout is overfilled and cannot flow out of the spout in time), increasing the frequency and difficulty of cleaning the spout. Furthermore, existing spouts are typically cleaned by disassembly, which involves removing the spout from the dispensing unit, cleaning the remaining coffee inside, and then reassembling it. However, the disassembly and reassembly of the dispensing unit and spout are cumbersome, and frequent cleaning negatively impacts the user experience. Summary of the Invention

[0004] The first technical problem this invention aims to solve is to provide a coffee spout that can prevent coffee liquid from spilling, in contrast to existing technologies.

[0005] The second technical problem to be solved by this invention is to provide a coffee spout that can prevent coffee spillage and is easy to clean and maintain in daily use, in contrast to the prior art.

[0006] The third technical problem to be solved by this utility model is to provide a coffee dispensing structure with the above-mentioned coffee spout, in contrast to the prior art.

[0007] The fourth technical problem to be solved by this utility model is to provide a coffee dispensing structure with the above-mentioned coffee spout and a robust internal structure, in contrast to the prior art.

[0008] The fifth technical problem to be solved by this utility model is to provide a coffee machine with the above-mentioned coffee dispensing structure, in contrast to the prior art.

[0009] The technical solution adopted by this utility model to solve at least one of the above-mentioned technical problems is as follows: a coffee spout, characterized in that it includes a vertically extending and hollow shell, the inner surface of the shell is smooth, the top of the shell is open and detachably covered with a cap, and the bottom has a liquid outlet located at the lowest point of the inner bottom surface of the shell. Furthermore, the upper end of the vertical side wall of the shell has a liquid inlet hole, the size of which is much smaller than the opening area of ​​the liquid outlet.

[0010] Furthermore, the shell has an elongated cross-section, with two outlets located at opposite ends of the bottom wall. The inlet is situated in the middle of its corresponding side wall along its width, and the width of each outlet matches the width of the bottom wall at its location. This design allows coffee flowing into the inlet to exit the shell more quickly through the outlets, better preventing spillage and minimizing coffee residue.

[0011] Furthermore, the bottom wall of the housing protrudes upwards in the middle to form a boss directly opposite the liquid inlet. Liquid outlets are respectively provided on both sides of this boss, and the two sides of the horizontally extending top surface of the boss are connected to the corresponding liquid outlets via guide slopes that slope outwards from top to bottom. Coffee liquid flowing into the inlet drips onto the top surface of the boss, and then flows into the corresponding liquid outlets under the guidance of the guide slopes on both sides. This guidance further accelerates the flow rate of the coffee liquid.

[0012] Furthermore, the sidewall of the housing containing the liquid inlet protrudes inward, forming a vertically extending bulge directly below the liquid inlet. The lower end of this bulge connects to the top of the aforementioned boss, and the cross-section of the bulge is arc-shaped. The top of the bulge bulge rises upward, making its top surface a frustum-shaped cone. The coffee liquid flowing in from the liquid inlet first flows to the boss, then flows to the boss under the guidance of the outer surface of the boss, and finally flows into each outlet under the guidance of the boss, further accelerating the flow rate of the coffee liquid.

[0013] Furthermore, the cover is provided with an air hole that communicates with the inner cavity of the aforementioned shell. The air hole balances the air pressure inside and outside the shell, ensuring that the coffee liquid can flow smoothly from the outlet.

[0014] Furthermore, the top surface of the cover is recessed to form a groove, and the aforementioned vent is located in this groove. Condensate formed when steam exits through the vent collects in the groove and then flows back into the shell through the vent, preventing condensate from flowing everywhere.

[0015] Furthermore, the channel of the liquid inlet is inclined downwards from the outside to the inside. This prevents coffee residue from remaining in the channel of the liquid inlet.

[0016] The technical solution adopted to further solve the second technical problem mentioned above is: a coffee dispensing structure, including a shell, characterized in that a coffee spout as described above is provided in the shell.

[0017] Furthermore, the outer casing extends vertically and includes a square-shaped liquid outlet body and a cover plate. The front of the liquid outlet body is recessed to form a receiving groove, and the outer surface of the casing has a vertically extending mounting protrusion on the outer side of the sidewall where the liquid inlet is located.

[0018] With the coffee spout installed in the housing, the aforementioned mounting protrusion is embedded in the aforementioned groove. The lower end of the mounting protrusion is detachably connected to the dispensing body, while the upper end is fixed to the dispensing body. The cover plate covers the front of the dispensing body, concealing the coffee spout, and is detachably connected to the dispensing body. By using the mounting protrusion on the housing, during spout installation, the coffee spout is first positioned by the engagement of the mounting protrusion with the groove, then the mounting protrusion is fixed to the dispensing body, and finally the cover plate conceals the coffee spout. When cleaning the coffee spout, simply remove the cover plate and the cap from the housing. Thanks to the housing's seamless internal design, the coffee spout can be cleaned directly without disassembling the entire spout for cleaning.

[0019] Furthermore, the liquid outlet body is hollow to form a cavity, and a window matching the size of the cavity is opened on the front of the liquid outlet body at the aforementioned cavity. The window communicates with the aforementioned cavity. A first connecting seat protrudes from the upper end of the aforementioned mounting protrusion. The first connecting seat passes through the aforementioned window and extends into the cavity of the outer shell, and is fixed to the second connecting seat at the upper end of the aforementioned window opening by fasteners.

[0020] The lower end of the mounting protrusion is provided with a first latching block, which also extends through the aforementioned window into the cavity of the outer casing and is latched to a second latching block at the lower edge of the aforementioned window. This achieves the fixation of the upper end of the mounting protrusion to the dispensing body and the detachable connection of the lower end of the mounting protrusion to the dispensing body, ensuring the stability of the coffee spout and the dispensing body installation.

[0021] The technical solution adopted to further solve the third technical problem mentioned above is: a coffee machine, characterized in that it includes the coffee dispensing structure described above.

[0022] Compared with existing technologies, the advantages of this invention are as follows: the inner surface of the shell is smooth, eliminating any dead corners inside. Furthermore, the size of the inlet hole is designed to be much smaller than the outlet opening, allowing coffee to flow out quickly after entering the shell. This prevents spillage and, combined with the elimination of dead corners, reduces coffee residue inside the shell, thus decreasing the frequency and difficulty of cleaning the spout. Additionally, the open design at the top of the shell facilitates daily cleaning and maintenance of the spout. Attached Figure Description

In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0036] A coffee machine, including such Figures 1-11 The coffee dispensing structure shown includes a housing 2 and a coffee spout 1 disposed within the housing 2. Further, as... Figures 1-4 As shown, the coffee spout 1 includes a vertically extending, hollow housing 11. The inner surface of the housing 11 is smooth, and the top of the housing 11 is open and detachably covered with a cap 13. A liquid outlet 111 is located at the lowest point of the inner bottom surface of the housing 11. Furthermore, a liquid inlet 112 is provided on the upper end of the vertical sidewall of the housing 11. The area of ​​the liquid inlet 112 is much smaller than the opening area of ​​the liquid outlet 111.

[0037] The inner surface of the housing 11 of the coffee spout 1 of this invention is smooth, eliminating any dead corners inside the housing 11. Simultaneously, the area of ​​the inlet hole 112 is designed to be much smaller than the opening area of ​​the outlet hole 111, allowing coffee to flow out quickly from the outlet hole 111 after entering the housing 11. This prevents coffee spillage and, combined with the design of eliminating dead corners inside the housing 11, reduces coffee residue inside, thus reducing the frequency and difficulty of cleaning the coffee spout 1. Furthermore, the open design at the top of the housing 11 facilitates daily cleaning and maintenance of the coffee spout 1.

[0038] like Figure 3As shown, in this embodiment, the cross-section of the housing 11 is elongated, and there are two outlets 111, respectively located at both ends of the bottom wall of the housing 11. The inlet hole 112 is located in the middle of its side wall along the width direction, and the width of each outlet 111 matches the width of the bottom wall of the housing 11 at its location. This design allows coffee liquid flowing in through the inlet hole 112 to flow out of the housing 11 more quickly through the outlets 111, better preventing spillage and reducing coffee residue. In this embodiment, the edge of each outlet 111 extends vertically downwards in the circumferential direction to form an outlet leg 1111, as shown... Figure 4 As shown.

[0039] Furthermore, such as Figure 4 As shown, the bottom wall of the aforementioned housing 11 has an upward-protruding boss 113 at its center, directly opposite the liquid inlet 112. Liquid outlets 111 are respectively provided on both sides of the boss 113. The two sides of the horizontally extending top surface of the boss 113 are connected to the corresponding liquid outlets 111 via guide slopes 1131 that slope outwards from top to bottom. Coffee liquid flowing into the inlet 112 drips onto the top surface of the boss 113, and then flows into the corresponding liquid outlets 111 under the guidance of the guide slopes 1131 on both sides. This guidance further accelerates the flow of coffee liquid. Furthermore, the sidewall of the housing 11 where the liquid inlet 112 is located protrudes inward to form a vertically extending bulge 114 directly below the liquid inlet 112. The lower end of the bulge 114 is connected to the top of the boss 113, and the cross-section of the bulge 114 is arc-shaped, while the top of the bulge 114 is raised upward, making the top surface of the bulge 114 a frustum-shaped surface. In this way, the coffee liquid flowing in from the liquid inlet 112 first flows to the boss 113, then flows to the boss 113 under the guidance of the outer surface of the boss 113, and finally flows into each liquid outlet 111 under the guidance of the boss 113, further accelerating the flow rate of the coffee liquid.

[0040] like Figure 1 and Figure 2 As shown, the cap 13 has an air hole 130 communicating with the inner cavity of the housing 11. The air hole 130 balances the air pressure inside and outside the housing 11, ensuring that the coffee liquid can flow smoothly from the outlet 111. Preferably, the top surface of the cap 13 is recessed to form a groove 131, and the air hole 130 is located in this groove 131 (e.g., ...). Figure 2 (As shown). The condensate formed when steam is discharged from the vent 130 collects in the groove 131, and then flows back into the shell 11 through the vent 130, preventing the condensate from flowing everywhere.

[0041] In addition, such as Figure 7 As shown, the channel of the liquid inlet 112 is inclined downward from the outside to the inside, which can prevent coffee liquid from remaining in the channel of the liquid inlet 112.

[0042] like Figures 5-11 As shown, the aforementioned outer casing 2 extends vertically and includes a square-shaped liquid outlet body 21 and a cover plate 22. The front of the liquid outlet body 21 is recessed to form a receiving groove 211 (as shown). Figure 9 As shown), the housing 11 has a vertically extending mounting protrusion 12 protruding from the outer side of the sidewall where the liquid inlet 112 is located. With the coffee spout 1 installed in the housing 2, the mounting protrusion 12 is embedded in the receiving groove 211. The lower end of the mounting protrusion 12 is detachably connected to the dispensing body 21, while the upper end is fixed to the dispensing body 21. A cover plate 22 covers the front of the dispensing body 21, shielding the coffee spout 1, and is detachably connected to the dispensing body 21. Simultaneously, each dispensing leg 111 extends from the through hole 20 at the bottom of the housing 2, as shown... Figure 5 As shown. By protruding mounting protrusions 12 on the housing 11, the coffee spout 1 is first positioned by the engagement of the mounting protrusion 12 with the receiving groove 211. Then, the mounting protrusion 12 is fixed to the dispensing body 21, and finally, the coffee spout 1 is covered by the cover plate 22. When cleaning the coffee spout 1, simply remove the cover plate 22 and the cover 13 on the housing 11. Thanks to the seamless design inside the housing 11, the coffee spout 1 can be cleaned directly without removing the entire coffee spout 1 from the dispensing body 21 for cleaning. In this embodiment, the mounting protrusion 12 is a vertically extending plate. A liquid inlet connector 1121 protrudes from the back of the mounting protrusion 12, extending along the channel direction of the liquid inlet hole 112 and communicating with the liquid inlet hole 112.

[0043] Furthermore, such as Figure 10 and Figure 11 As shown, in this embodiment, the liquid outlet body 21 is hollow to form a cavity 210. A window 212, matching the size of the receiving groove 211, is opened on the front of the liquid outlet body 21 at the aforementioned receiving groove 211. This window 212 communicates with the cavity 210. A first connecting seat 121 protrudes from the upper end of the mounting protrusion 12. This first connecting seat 121 passes through the window 212 and extends into the cavity 210 of the outer casing 2, and is fixed to a second connecting seat 213 at the upper edge of the window 212 by a fastener 3 (specifically a screw in this embodiment). A first latching block 122 protrudes from the lower end of the mounting protrusion 12. This first latching block 122 also passes through the window 212 and extends into the cavity 210 of the outer casing 2, and is latched to a second latching block 214 at the lower edge of the window 212. This achieves the fixation of the upper end of the mounting protrusion 12 to the liquid dispensing body 21, and the detachable connection of the lower end of the mounting protrusion 12 to the liquid dispensing body 21, ensuring the stability of the coffee spout 1 and the liquid dispensing body 21.
