[0002] With the upgrading of consumption and the acceleration of the pace of life, self-service beverage machines have been widely used in office buildings, shopping malls, campuses, transportation hubs and other scenarios due to their advantages of 24-hour unattended operation, instant drinking and diverse flavors. They have become an important branch of the freshly made beverage industry. Their core needs are to achieve precise proportioning of multiple raw materials, automated preparation, hygiene and safety assurance, as well as miniaturization and intelligent upgrading to adapt to different consumption scenarios.

[0003] To address the aforementioned issues, existing patents offer solutions. However, current self-service beverage machines lack a structure for multi-pipeline diversion and delivery of different beverages. This makes it impossible to independently deliver and proportion multiple ingredients such as syrup, tea, milk, water, and toppings. Consequently, they cannot meet users' demands for personalized beverages such as three-tenths sugar, iced milk tea, or double milk coffee. Furthermore, since multiple ingredients share the same pipeline or mixing chamber, incomplete cleaning can easily leave residues from previous ingredients, affecting not only the flavor of the beverage but also posing hygiene and safety risks, thus reducing the taste of the beverage.

[0004] Therefore, a multi-pipeline pumping mechanism for self-service beverage machines is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] The multi-pipe pumping mechanism of the self-service beverage machine includes the self-service beverage machine body 1, a storage mechanism 2 is provided at the bottom of the rear side of the self-service beverage machine body 1, and a liquid extraction mechanism 3 is welded to the top of the storage mechanism 2.

[0029] The storage mechanism 2 includes an installation slot 21, a protective door 22, a combination lock 23, five liquid storage tanks 24, a liquid level sensor 25, a filling pipe 26, a suction pipe 27, and a solenoid one-way valve 28;

[0030] The liquid extraction mechanism 3 includes a mounting plate 31, a lower five-way diversion pipe 32, a liquid extraction pump 33, a discharge pipe 34, a limiting groove 35, an upper five-way diversion pipe 36, an electromagnetic flow meter 37, and a PLC controller 38.

[0031] Mounting plate 31 is welded to the top of liquid storage tank 24, lower five-way diversion pipe 32 is fixedly connected to the top of electromagnetic single-way valve 28, and liquid pump 33 is mounted on the top of mounting plate 31.

[0032] In this embodiment: by setting the self-service beverage machine body 1 to provide a stable installation space and positioning benchmark for the storage mechanism 2 and the liquid pumping mechanism 3, and the user can place an order through the front touch screen, the self-service beverage machine body 1 transmits the order data to the PLC controller 38, the mounting plate 31 can support and limit the liquid pump 33, and the lower five-way diversion pipe 32 realizes the centralized convergence of five raw material pipelines, and uniformly transports the raw materials of each liquid storage tank 24 to the liquid pump 33. The liquid pump 33 provides a power source for the raw material transportation, driving the raw materials of each liquid storage tank 24 to flow along the pipeline.

[0033] Specifically, such as Figure 3 As shown, the rear side of the lower five-way diversion pipe 32 is fixedly connected to the front side of the liquid pump 33, the drain pipe 34 is fixedly connected to the rear side of the liquid pump 33, the limiting groove 35 is opened on the inner side of the front side of the self-service beverage machine body 1, the upper five-way diversion pipe 36 is installed on the inner side of the limiting groove 35, the top of the drain pipe 34 passes through the limiting groove 35 and is fixedly connected to the rear side of the upper five-way diversion pipe 36, the electromagnetic flow meter 37 is installed at the bottom of the upper five-way diversion pipe 36, the bottom of the upper five-way diversion pipe 36 is fixedly connected to the top of the liquid outlet of the self-service beverage machine body 1, and the PLC controller 38 is installed on the right side inside the mounting groove 21.

[0034] Specifically, such as Figure 4 , Figure 5 As shown, the mounting slot 21 is located at the bottom of the rear side of the self-service beverage machine body 1. The protective door 22 is rotatably connected to the rear side of the mounting slot 21. The combination lock 23 is installed on the right rear side of the protective door 22. The liquid storage tank 24 is installed at the bottom of the inner side of the mounting slot 21. The liquid level sensor 25 is installed at the bottom of the rear side of the liquid storage tank 24.

[0035] Specifically, such as Figure 4 , Figure 5 As shown, the detection end of the liquid level sensor 25 extends through and into the inner side of the liquid storage tank 24, the filling pipe 26 is fixedly connected to the top of the rear side of the liquid storage tank 24, the liquid extraction pipe 27 is fixedly connected to the front side of the top of the liquid storage tank 24, the top of the liquid extraction pipe 27 extends through and into the outer side of the top of the mounting plate 31, and the electromagnetic one-way valve 28 is installed on the top of the liquid extraction pipe 27.

[0036] In this embodiment: by setting up a drain pipe 34 to connect the pump 33 and the upper five-way diversion pipe 36, the raw material is transported from the pumping mechanism 3 to the outlet. The limiting groove 35 provides a dedicated installation and positioning space for the upper five-way diversion pipe 36, restricting the displacement of the upper five-way diversion pipe 36. The upper five-way diversion pipe 36 realizes the re-diversion of the raw material, accurately distributing the raw material transported by the pump 33 to the corresponding outlet. The electromagnetic flowmeter 37 monitors the raw material flow rate of each branch of the upper five-way diversion pipe 36 in real time and feeds back the data. The PLC controller 38 controls the raw material conveying volume. It receives monitoring data from the electromagnetic flowmeter 37 and the level sensor 25, controlling the on / off state of the electromagnetic single-way valve 28 and the operating status of the pump 33. Based on user orders, it automatically matches beverage formulas, achieving automated conveying of multiple raw materials. The installation slot 21 provides installation space for the storage tank 24 and the pumping mechanism 3. The protective door 22 provides a sealed protection for the storage tank 24 and the pumping mechanism 3 within the installation slot 21, preventing dust and other contaminants from entering. Impurities entering and contaminating raw materials, while preventing unauthorized personnel from accessing internal components, are prevented from being stolen, maliciously replaced, or operated by unauthorized personnel. The combination lock 23 and protective door 22 work together to achieve security control, preventing theft, malicious replacement, or unauthorized operation of raw materials, improving the safety of the self-service beverage machine 1 in unattended scenarios, and reducing operational risks. The liquid storage tank 24 adopts a multi-tank independent design, which can store different beverage raw materials such as syrup, tea, and milk separately, supporting the free combination and preparation of multiple flavors. The liquid level sensor 25 monitors the remaining amount of raw materials in the liquid storage tank 24 in real time. When the raw materials are insufficient, an alarm can be triggered by the PLC controller 38, which facilitates replenishment by maintenance personnel. The filling pipe 26 provides a convenient operation interface for maintenance personnel to replenish raw materials. The liquid extraction pipe 27 connects the liquid storage tank 24 to the liquid extraction mechanism 3, providing a channel for raw material transportation. The electromagnetic single-way valve 28 controls the on / off supply of raw materials in each liquid storage tank 24, and works with the PLC controller 38 to realize the on-demand transportation of multiple raw materials. The single-way structure can effectively prevent raw material backflow and avoid mixing and contamination of raw materials from different pipelines.

[0037] Specifically, such as Figure 3 As shown, the rear thread of the filling tube 26 is connected to a sealing cap 4, and the surface of the sealing cap 4 is engraved with anti-slip texture.

[0038] Specifically, such as Figure 4 As shown, a handle 5 is welded to the rear side of the protective door 22, and the surface of the handle 5 is engraved with anti-slip texture.

[0039] In this embodiment: by setting a sealing cap 4, which is threadedly connected to the rear side of the filling pipe 26, the filling pipe 26 is sealed and protected to prevent dust and impurities from entering the storage tank 24 and contaminating the raw materials. By setting anti-slip texture, the friction force when turning is increased, making it easy for maintenance personnel to open and close quickly. By setting a handle 5, a convenient force point is provided for maintenance personnel to open the protective door 22. By setting anti-slip texture, the friction force between the maintenance personnel's hands and the handle 5 is increased.

[0040] Specifically, such as Figure 4 As shown, three heat dissipation vents 6 are provided on both sides of the mounting slot 21, and a dust filter is movably connected to the inner side of the heat dissipation vent 6.

[0041] Specifically, such as Figure 3 As shown, a reinforcing base 7 is welded to the bottom of the pump 33, and the bottom of the reinforcing base 7 is welded to the top of the mounting plate 31.

[0042] In this embodiment: by setting heat dissipation vent 6, air circulation between the inside of the mounting slot 21 and the outside is realized, and the heat generated by the operation of electrical components such as liquid level sensor 25 and electromagnetic one-way valve 28 is dissipated in time, so as to avoid component failure due to overheating. By setting dust filter screen, external dust can be blocked from entering, ensuring the cleanliness of internal components. By setting reinforcing base 7, the installation contact area of ​​liquid pump 33 is increased, effectively dispersing the vibration of liquid pump 33 during operation and reducing the risk of loosening at pipe joints.

[0043] Working Principle: First, the user places a beverage order via the touchscreen on the front of the self-service beverage machine 1. The order data is transmitted to the PLC controller 38 in real time. The PLC controller 38 matches the corresponding beverage ingredient formula according to the order requirements and simultaneously retrieves the monitoring data from the liquid level sensors 25 in each liquid storage tank 24. After confirming that all required ingredients are sufficient, the machine is started and enters the ingredient delivery preparation state. Then, the PLC controller 38 sends an opening command to the solenoid single-way valve 28 on the top suction pipe 27 of the corresponding ingredient liquid storage tank 24, opening the ingredient delivery path from the liquid storage tank 24 to the suction mechanism 3. Subsequently, the suction pump 33 is started. The suction pump 33 generates power to drive the ingredients in the liquid storage tank 24 into the lower five-way diversion pipe 32 through the suction pipe 27. The lower five-way diversion pipe 32 centrally collects the ingredients from the five independent pipes and then delivers them to the upper five-way diversion pipe 36 inside the limiting groove 35 through the discharge pipe 34 behind the suction pump 33. Afterwards, the raw materials enter the upper five-way diversion pipe 36, which redistributes the raw materials to the corresponding branches and delivers them to the dispensing nozzle of the self-service beverage machine body 1. During this process, the electromagnetic flowmeter 37 monitors the raw material flow rate of each branch in real time and continuously feeds the flow data back to the PLC controller 38. The PLC controller 38 dynamically adjusts the speed of the pump 33 according to the preset formula parameters to ensure that the delivery volume of each raw material matches the formula requirements. Finally, when all raw materials are delivered to the dispensing nozzle in a quantitative manner and the mixing and dispensing of the cup are completed, the PLC controller 38 sends a command to shut down the pump 33 and close all electromagnetic single-way valves 28 at the same time to block the raw material delivery path and prevent raw material backflow. After a single beverage preparation is completed, the equipment remains in standby mode, waiting for the next order instruction. If the liquid level sensor 25 detects that the remaining raw material in a certain storage tank 24 is insufficient, the PLC controller 38 will immediately trigger an early warning prompt, so that maintenance personnel can replenish the raw materials in time through the filling pipe 26.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
