[0023] 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.

[0024] This utility model provides, for example Figure 1-5 The illustrated filtering structure of a self-service beverage machine includes a U-shaped beverage machine main unit 1 and a beverage storage box 5 located at the top of the U-shaped beverage machine main unit 1. The beverage storage box 5 contains multiple categorized beverage storage compartments 6, all with upward-facing openings. Each of the multiple categorized beverage storage compartments 6 contains a cuboid filter box 7, and each cuboid filter box 7 has a filter bottom screen 12 at its bottom. Both the cuboid filter box 7 and the filter bottom screen 12 are made of food-grade stainless steel. The filter bottom screen 12 effectively filters out larger particles of impurities as the beverage passes through. A baffle frame 13 is located at the top of the cuboid filter box 7 for mounting... The outer length and width of the baffle frame 13 are larger than the outer length and width of the cuboid filter box 7. A frame-type baffle is provided on the upper side of the center of the inner wall of the classified beverage storage chamber 6. The baffle frame 13 is placed on the frame-type baffle. A sealing gasket is also provided on the outer wall of the bottom end of the baffle frame 13. The sealing gasket can be tightly attached to the outer wall of the top of the frame-type baffle. A storage chamber sealing cover 9 is placed inside the top opening of the classified beverage storage chamber 6. The storage chamber sealing cover 9 is located at the top of the baffle frame 13. The baffle frame 13 ensures the stable placement of the cuboid filter box 7 in the storage chamber, preventing the filter box from shaking or shifting during beverage injection and filtration, and ensuring the stable operation of the filtration process.

[0025] like Figure 1 , Figure 2 and Figure 3As shown, a self-service touch screen 10 is installed at the front of the beverage storage tank 5. The self-service touch screen 10 is flush with the front and left and right outer walls of the U-shaped beverage machine main unit 1. Multiple beverage discharge valves 3 are equidistantly arranged inside the front top of the center of the U-shaped beverage machine main unit 1. The bottom ends of the multiple beverage discharge valves 3 are exposed on the lower side of the inner wall of the top of the U-shaped beverage machine main unit 1. The self-service touch screen 10 facilitates user operation and selection of the desired beverage type. When the user selects a specific beverage type, the beverage discharge valve 3 opens, and the beverage is discharged from the corresponding beverage storage chamber 6. After preliminary filtration by the cuboid filter box 7 and fine adsorption filtration by the adsorption filter device 8, the beverage is finally discharged from the beverage discharge valve 3 for the user to drink. The U-shaped opening of the U-shaped beverage machine main unit 1 faces forward, and multiple beverage types are equidistantly arranged inside the outer wall of the front top of the U-shaped beverage machine main unit 1. The beverage type label 4 has the same number as the multiple beverage category storage compartments 6, and there is a one-to-one correspondence between the multiple beverage type label 4 and the multiple beverage category storage compartments 6. Each of the multiple beverage type label 4 has an opening button 11 on its lower side. The bottom of the U-shaped beverage machine main unit 1 is hollow, and a placement mesh frame 2 is set inside the bottom inner wall of the U-shaped beverage machine main unit 1. The placement mesh frame 2 is located directly below the multiple beverage discharge valves 3. The placement mesh frame 2 is used to catch the beverages discharged from the beverage discharge valves 3 to prevent the beverages from dripping and dirtying the ground. It also facilitates the subsequent collection and processing of the discharged beverages. The design concept of the entire filtration structure is to ensure that the beverages discharged from the self-service beverage machine are pure, hygienic, and free of impurities and harmful substances through multi-layer filtration and protection measures, so as to provide users with a high-quality beverage drinking experience.

[0026] like Figure 1 , Figure 4 and Figure 5As shown, an adsorption filtration device 8 is provided at the bottom of the filter screen 12. The adsorption filtration device 8 includes an activated carbon adsorption pack 14, a flat rectangular adsorption box 16, liquid inlet and outlet slots 17, and fixed hanging rods 18. Fixed hanging rods 18 are fixed at the four corners of the bottom of the filter screen 12. The bottom ends of multiple fixed hanging rods 18 are connected to the flat rectangular adsorption box 16. The fixed hanging rods 18 firmly connect the flat rectangular adsorption box 16 to the filter screen 12, ensuring the stability of the adsorption filtration device 8 during operation and preventing displacement or shaking due to the impact of beverage flow. Multiple liquid inlet and outlet slots 17 are equidistantly arranged inside the top, bottom, left, and right ends of the flat rectangular adsorption box 16. The activated carbon adsorption pack 14 is provided inside the flat rectangular adsorption box 16. The activated carbon adsorption pack 14 is the core part of the adsorption filtration device 8. It has a strong adsorption capacity and can efficiently adsorb various small impurities, odors, pigments, and other substances remaining in the beverage. To remove harmful chemicals, the adsorption and filtration device 8 also includes multiple soft rubber anti-detachment baffles 15. The front end of the flat rectangular adsorption box 16 is open, and multiple soft rubber anti-detachment baffles 15 are equidistantly fixed on the outer wall of the top front end of the flat rectangular adsorption box 16. The outer wall of the bottom end of the soft rubber anti-detachment baffles 15 is located on the upper side of the inner wall of the bottom end of the flat rectangular adsorption box 16. The design of the flat rectangular adsorption box 16 serves to accommodate and fix the activated carbon adsorption pack 14. Multiple liquid inlet and outlet slots 17 are equidistantly arranged at both the top and bottom ends and the left and right ends. On the one hand, this ensures that the beverage can slowly pass through the flat rectangular adsorption box 16 under the action of pressure difference, allowing the beverage enough time to fully contact the activated carbon adsorption pack 14 for adsorption and filtration. On the other hand, these slots also prevent the activated carbon adsorption pack 14 from randomly escaping from the flat rectangular adsorption box 16, ensuring that the activated carbon adsorption pack 14 always remains in the predetermined position during the adsorption and filtration process.

[0027] like Figure 1 , Figure 4 and Figure 5As shown, the cross-sectional shape and area of ​​the flat rectangular adsorption box 16 are the same as those of the filter bottom screen 12. The soft rubber anti-detachment baffle 15 can be elastically bent in the front and back directions. The soft rubber anti-detachment baffle 15 is made of food-grade soft rubber. The soft rubber anti-detachment baffle 15 can prevent the activated carbon adsorption pack 14 from detaching from the inside of the flat rectangular adsorption box 16. The setting of the soft rubber anti-detachment baffle 15 is very critical. It is made of food-grade soft rubber and can be elastically bent in the front and back directions. When the activated carbon adsorption pack 14 may change its volume during the adsorption process, the soft rubber anti-detachment baffle 15 can elastically deform accordingly and always stick tightly to the inner wall of the flat rectangular adsorption box 16, like a reliable "guardian". It effectively prevents the activated carbon adsorption pack 14 from detaching from the inside of the flat rectangular adsorption box 16, avoiding the situation where the entire adsorption filtration device 8 loses its filtration function due to the detachment of the activated carbon adsorption pack 14. This ensures that the adsorption filtration device 8 can work stably for a long time and provides a reliable guarantee for the filtration and purification of beverages, so that the self-service beverage machine can provide users with high-quality, pure and hygienic beverages.
