[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Reference Figures 1-3 The illustrated anti-clogging commercial self-service coffee machine includes a main body 1 and a bean storage compartment 2 located inside the main body 1. The main body 1 utilizes an automated mechanical structure, electronic control system, and sensors to work together to achieve a fully self-service process from user order placement to coffee preparation. Its core is to transform the traditional manual steps of coffee making (such as grinding, extraction, adding milk, and flavoring) into standardized mechanical actions, while simultaneously enhancing the user experience through a payment system and interactive interface.

[0034] For example: the user selects "latte" on the touch screen, the interface displays the price, and after successful payment by scanning the code, the payment module sends a confirmation signal to the main control board. The grinder starts, and the "latte" preset amount of coffee powder is ground. The extraction device receives the coffee powder and compacts it. The water pump starts, and 92℃ hot water is injected at a pressure of 10 bar to extract the coffee liquid, which flows into the cup below the cup holder. The steam system starts, and the milk is pumped from the milk cylinder to the steam pipe. The steam heats the milk to 60-65℃, while the delicate milk foam is ejected. The heated milk and milk foam are injected into the coffee liquid in proportion. The coffee flows into the user's cup, and after the cup is removed, the extraction device is automatically rinsed, the steam pipe releases residual steam, and the interface displays "take the cup complete". During use, the main control board inside the machine 1 updates the raw material quantity data in real time (such as the amount of milk reduction), and if it approaches the threshold (such as when the amount of milk is less than 20%), the background sends a restocking reminder, and the staff can replenish the goods in time.

[0035] As shown in Figure 4 In the present application, since the machine body 1 is mostly located in public places, in order to meet the demand for coffee supply of large flow, a large amount of coffee beans are usually stored in the coffee bean storage bin 2. The coffee bean storage bin 2 is provided with a discharge pipe 21 at the bottom end, and a rotatable drive main shaft 4 is arranged at the center position of the inner side of the coffee bean storage bin 2. The drive main shaft 4 is fixed with a connecting support 5 at the bottom end, and a plurality of arc-shaped stirring bars 6 are arranged on the side surface of the connecting support 5 along the circumferential track at equal intervals. The arc-shaped stirring bars 6 are all in C-shaped structure, and the end of the arc-shaped stirring bars 6 away from the connecting support 5 is distributed upward. The bottom end of each of the plurality of arc-shaped stirring bars 6 is provided with an arc-shaped dispersing bar 7, and the arc-shaped dispersing bars 7 are opposite to the upper side of the discharge pipe 21. During the storage of coffee beans, the arc-shaped stirring bars 6 and the arc-shaped dispersing bars 7 rotate synchronously with the rotation of the drive main shaft 4.

[0036] The arc-shaped stirring bars 6 can stir the coffee beans accumulated in the coffee bean storage bin 2, effectively avoiding the adhesion and hardening of a large amount of coffee beans accumulated in the coffee bean storage bin 2, ensuring the loose degree of the coffee beans. When the coffee beans are continuously made and fall through the discharge pipe 21 to the grinding equipment, the phenomenon of blocking the discharge pipe 21 caused by the adhesion of the coffee beans can be avoided.

[0037] When a large amount of coffee beans are accumulated in the coffee bean storage bin 2, under the action of gravity, the coffee beans at the lowermost part near the discharge pipe 21 are prone to adhesion and hardening. During the process of discharging the coffee beans to the grinding equipment, the coffee beans are prone to flow poorly. Therefore, as shown in Figure 4 The arc-shaped dispersing bars 7 in the present application can perform stirring and dispersing operations above the discharge pipe 21 during rotation, avoiding the poor flow of coffee beans caused by the accumulation of a large amount of coffee beans, and further improving the smoothness during the discharging process of the coffee beans.

[0038] Further, in the process of discharging coffee beans to the grinding device, the coffee beans located at the lower part of the storage bin 2 fall first, and the coffee beans located at the upper part of the storage bin 2 fall slowly. If the coffee machine 1 is used to make a small amount of coffee, the coffee beans located at the upper part of the storage bin 2 fall even more slowly. In order to avoid the coffee beans located at the upper part of the storage bin 2 from adhering to the inner wall of the storage bin 2, as shown in FIG. Figure 4 In the present application, a plurality of arc-shaped push rods 8 are arranged above the arc-shaped stirring bars 6 at equal intervals along the circumferential track and are in contact with the inner wall of the storage bin 2. With the reciprocating rotation of the driving main shaft 4, the arc-shaped stirring bars 6 and the arc-shaped dispersing bars 7 rotate synchronously in the storage bin 2, and the arc-shaped push rods 8 move up and down along the inner wall of the storage bin 2.

[0039] In the process of moving up and down, the arc-shaped push rods 8 can continuously push the coffee beans, so that the coffee beans are separated from the inner wall of the storage bin 2, thereby effectively avoiding the adhesion between the coffee beans located at the upper part of the storage bin 2 and the inner wall of the storage bin 2, improving the looseness of the coffee beans located at the upper part of the storage bin 2, and ensuring that the coffee beans located at the upper part of the storage bin 2 can be normally discharged.

[0040] Specifically, as shown in FIG. Figure 5 , Figure 6 The part of the driving main shaft 4 exposed to the outside of the storage bin 2 is provided with a first driving ring 41 which can rotate synchronously with the driving main shaft 4. The outer periphery of the first driving ring 41 is fixedly provided with an outer gear ring 42. The outer periphery of the outer gear ring 42 is engagedly connected with a plurality of first synchronous gears 43 arranged at equal intervals along the circumferential track. The central axis positions of the first synchronous gears 43 are each provided with a screw rod 44 which can rotate synchronously with the first synchronous gears 43. The screw rod 44 is provided with a linkage frame 45 matched therewith. A plurality of arc-shaped push rods 8 are respectively arranged at the bottom ends of the plurality of linkage frames 45. When the outer gear ring 42 engages the first synchronous gears 43 to rotate reciprocatingly, the screw rods 44 rotate reciprocatingly, the linkage frames 45 and the arc-shaped push rods 8 move up and down, and the arc-shaped push rods 8 move up and down synchronously in the storage bin 2, so as to continuously push the coffee beans and separate the coffee beans from the inner wall of the storage bin 2.

[0041] In the actual use of the commercial coffee machine, since the discharge pipe is arranged at the bottom center, with the continuous making of coffee, the coffee beans in the center of the storage bin 2 fall faster in the process of falling, and the coffee beans are prone to form a phenomenon of high outer circle and low center in the storage bin 2.

[0042] In the process of supplementing coffee beans into the storage bin 2, in order to avoid the accumulation of coffee beans at a certain position in the storage bin 2 with the introduction of a large amount of coffee beans, as shown in FIG. Figure 9 , Figure 10As shown, in the present application, the inside of the coffee bean storage bin 2 is provided with a flow guide frame 3, the flow guide frame 3 is located above the arc-shaped stirring strip 6, the arc-shaped dispersing strip 7 and the arc-shaped push rod 8, and the flow guide frame 3 is in a funnel-shaped structure and surrounds the outside of the driving main shaft 4, the linkage frame 45 penetrates the flow guide frame 3, and the coffee beans falling through the opening of the coffee bean storage bin 2 fall along the surface of the flow guide frame 3.

[0043] Therefore, in the process of replenishing the coffee beans in the coffee bean storage bin 2, based on the arrangement of the flow guide frame 3, the coffee beans can be made to fall towards the center of the coffee bean storage bin 2, and the coffee beans can be smoothly replenished to the center of the inside of the coffee bean storage bin 2, avoiding the phenomenon that the coffee beans are concentrated and accumulated in the outer circle of the inside of the coffee bean storage bin 2 due to the falling of a large amount of coffee beans during the replenishment process.

[0044] Further, as shown in Figure 7 , Figure 8 , the bottom end of the first driving ring 41 is fixed with a second driving ring 46, the inside of the second driving ring 46 is provided with an inner tooth ring 47, the inner periphery of the inner tooth ring 47 is meshingly connected with a plurality of second synchronous gears 48 arranged equidistantly along the circumferential track, the central axis positions of the second synchronous gears 48 are each provided with an extension rod 49 which can rotate synchronously therewith, the bottom end of the extension rod 49 is fixed with a flow guide plate 9, and the extension rod 49 and the flow guide plate 9 rotate synchronously with the synchronous rotation of the first driving ring 41 and the second driving ring 46.

[0045] In the process of synchronous rotation of the extension rod 49 and the flow guide plate 9, part of the coffee beans falling towards the center of the coffee bean storage bin 2 can be guided to the remaining positions of the coffee bean storage bin 2, the uniformity of the distribution of the coffee beans during the replenishment process is improved, the replenishment operation of a large amount of coffee beans in the inside of the coffee bean storage bin 2 can be quickly implemented, the time required for manual arrangement of the coffee beans is reduced, and the efficiency of the replenishment operation is improved.

[0046] In the present application, as shown in Figure 10 , in order to uniformly guide the falling coffee beans by the plurality of flow guide plates 9, a plurality of extension rods 49 surrounds the outside of the driving main shaft 4, the extension rod 49 penetrates the inside edge of the flow guide frame 3, and the flow guide plate 9 is located below the flow guide frame 3.

[0047] As shown in Figure 5 , the opening of the coffee bean storage bin 2 is provided with a bottom cover 23, the top of the bottom cover 23 is provided with a top cover 24, the driving main shaft 4 penetrates the bottom cover 23 and extends into the opposite space of the top cover 24 and the bottom cover 23, and the top cover 24 is provided with a driving motor 26 which can drive the driving main shaft 4 to rotate. The driving motor 26 can provide power source for the rotation of the driving main shaft 4, the first driving ring 41 and the second driving ring 46, so as to achieve the purpose of driving the first synchronous gear 43 and the second synchronous gear 48 to rotate.

[0048] As shown in Figure 5 ,Figure 6 As shown, in order to maintain the stability of the first synchronization gear 43 and the second synchronization gear 48, the second driving ring 46 is rotatably mounted on the inner bottom wall of the bottom cover 23, and in order to maintain the stability of the first synchronization gear 43 and the second synchronization gear 48, the first synchronization gear 43 and the second synchronization gear 48 are rotatably mounted in the opposite space of the top cover 24 and the bottom cover 23, and the linkage frame 45 and the extension rod 49 are both penetrated through the bottom cover 23.

When the sealing frame 25 is separated from the bottom cover 23 and the top cover 24, part of the flow guide frame 3 is exposed, leaving a space for pouring coffee beans into the inside of the bean storage bin 2.

[0050] As shown, Figure 3 As shown, the discharge pipeline 21 is provided with an electric control valve 22, and the electric control valve 22 is in communication connection with the machine body 1.
