[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0040] Reference Figure 1-7 A beverage dispensing machine that is easy to clean includes a liquid storage tank 1 and a liquid dispensing tank 2 integrally connected to the side of the liquid storage tank 1, characterized in that:

[0041] The liquid storage cabinet 1 has a raw material storage cavity 3 for storing ingredients, and a hinged cabinet door is connected to the front of the liquid storage cabinet 1 at the position corresponding to the raw material storage cavity 3.

[0042] Multiple layered partitions 4 for supporting ingredient containers are arranged vertically in the raw material storage chamber 3. Each layered partition 4 has multiple liquid storage boxes 5 for storing different beverage ingredients placed at its top.

[0043] Multiple peristaltic pumps 8 for conveying and dispensing ingredients are fixedly installed on the inner wall of the raw material storage chamber 3, and the peristaltic pumps 8 correspond one-to-one with the liquid storage box 5.

[0044] The inlet end of the peristaltic pump 8 and the outlet end of the liquid storage box 5 are both coaxially equipped with quick-release connectors 6. The peristaltic pump 8 and the liquid storage box 5 are connected through liquid guiding hoses 7 inserted into the corresponding quick-release connectors 6 at both ends.

[0045] The end of the quick-release connector 6 away from the liquid guiding hose 7 is coaxially fixed to the mounting ring 12. The outer side of the quick-release connector 6 is slidably sleeved with a movable sleeve 9, and a reset spring 10 for driving the movable sleeve 9 to reset is coaxially sleeved between the movable sleeve 9 and the mounting ring 12.

[0046] The outer wall of the quick-release connector 6 is provided with a plurality of annularly arrayed ball holes 61, and each ball hole 61 is movably fitted with a limiting ball 62.

[0047] An annular groove is provided on the outer side of the liquid guiding hose 7 at the position corresponding to the limiting ball 62. The limiting ball 62 can be partially inserted into the annular groove to achieve axial positioning of the liquid guiding hose 7 and the quick-release connector 6.

[0048] The movable sleeve 9 has a relief cavity 92 at one end near the liquid guiding hose 7, and the limiting ball 62 can partially move into the relief cavity 92 to release the limitation on the liquid guiding hose 7.

[0049] Using the above technical solution, the layered partition 4 inside the raw material storage chamber 3 cooperates with the liquid storage box 5 to achieve partitioned storage of ingredients, avoiding cross-contamination. Furthermore, the liquid storage box 5 can be directly removed for cleaning, solving the problem of difficult cleaning of traditional fixed liquid storage components. The peristaltic pump 8 is connected to the liquid storage box 5 via a quick-release connector 6 and a liquid guiding hose 7. The upper limit ball 62 of the quick-release connector 6 cooperates with the annular groove of the liquid guiding hose 7 to quickly lock the hose, ensuring a tight seal during delivery. Pushing the movable sleeve 9 causes the upper limit ball 62 to enter the clearance cavity 92, allowing the hose to be disassembled without tools. The return spring 10 assists in the reset of the movable sleeve 9, significantly shortening the disassembly time and facilitating cleaning of the inner wall of the hose and the inside of the connector, preventing residual ingredients from deteriorating and meeting hygiene standards.

[0050] Both ends of the fluid guiding hose 7 are integrally injection molded with a first tube head 71, and the end of the first tube head 71 away from the fluid guiding hose 7 is integrally molded with a second tube head 72, and the outer diameter of the second tube head 72 is smaller than the outer diameter of the first tube head 71.

[0051] The quick-release connector 6 has a stepped opening at one end near the fluid guiding hose 7. The stepped opening includes a first stepped hole that matches the outer diameter of the first tube head 71 and a second stepped hole that matches the outer diameter of the second tube head 72. The first stepped hole and the second stepped hole are coaxially arranged, and an annular groove is circumferentially opened on the outer wall of the first tube head 71.

[0052] By adopting the above technical solutions, the connection structure between the fluid guiding hose 7 and the quick-release connector 6 is optimized, improving the accuracy and stability of the fit. The first tube head 71 and the second tube head 72 at both ends of the fluid guiding hose 7 form a stepped structure, which is precisely matched with the first stepped hole and the second stepped hole on the inner side of the quick-release connector 6 to achieve coaxial positioning, avoid leakage caused by installation deviation, and reduce the amount of cleaning work for residues. At the same time, the insertion depth of the hose is limited to ensure consistent installation position and reduce the probability of failure. The annular groove is opened on the outside of the first tube head 71 to make the engagement position of the limiting ball 62 clear.

[0053] The inner side of the movable sleeve 9 is provided with an annular fitting part 91, and the inner wall of the annular fitting part 91 slides and fits against the outer wall of the first tube head 71.

[0054] The movable sleeve 9 has a receiving cavity 93 on the inner side of one end near the mounting ring 12. One end of the return spring 10 extends into the receiving cavity 93 and abuts against the end of the annular fitting part 91, while the other end abuts against the end face of the mounting ring 12 near the movable sleeve 9.

[0055] The inner diameter of the clearance cavity 92 is larger than the outer diameter of the first pipe head 71, and the gap between the inner wall of the clearance cavity 92 and the outer wall of the first pipe head 71 is greater than the depth of the annular groove.

[0056] Using the above technical solution, the inner annular fitting part 91 of the movable sleeve 9 slides and fits against the outer wall of the first tube head 71, guiding the movable sleeve 9 and preventing displacement that could lead to unlocking failure; the receiving cavity 93 provides a stable installation space for the reset spring 10, ensuring uniform spring force and preventing deformation from affecting the reset of the movable sleeve 9, eliminating the need for manual adjustment and improving operational efficiency; the gap design between the clearance cavity 92 and the first tube head 71 ensures that the limiting ball 62 can completely disengage from the annular groove, thoroughly releasing the hose limit and preventing jamming that could make the hose difficult to disassemble.

[0057] The outer wall of the second tube head 72 is provided with an annular sealing groove, and a food-grade silicone sealing ring is fitted inside the annular sealing groove.

[0058] Using the above technical solution, a food-grade silicone ring is fitted inside the annular sealing groove on the outer side of the second pipe head 72. The silicone has good elasticity and corrosion resistance, and fits tightly against the inner wall of the second stepped hole of the quick-release connector 6 to form a reliable sealing surface, preventing the filling material from leaking out of the gap.

[0059] The diameters of the openings at both ends of the ball hole 61 are smaller than the diameter of the limiting ball 62, and the inner diameter of the ball hole 61 is matched with the diameter of the limiting ball 62. The limiting ball 62 is made of stainless steel.

[0060] By adopting the above technical solution, the mating relationship and material of the ball hole 61 and the limiting ball 62 are defined to ensure the stability of the locking function of the quick-release connector 6. The diameter of the openings at both ends of the ball hole 61 is smaller than the diameter of the limiting ball 62 to prevent the limiting ball 62 from falling off, reducing failures and maintenance costs; the inner diameter of the ball hole 61 is adapted to the diameter of the limiting ball 62 to ensure the flexible movement of the limiting ball 62, ensuring smooth locking and unlocking, and avoiding excessive clearance that could cause shaking and affect stability.

[0061] One end of the mounting ring 12 near the quick-release connector 6 is coaxially fixed to the limiting tube 11. The limiting tube 11 has an opening at one end facing the movable sleeve 9. The inner diameter of the opening is smaller than the inner diameter of the limiting tube 11, forming an annular limiting step.

[0062] A limiting ring 94 is coaxially fixed to the outer circumferential surface of the movable sleeve 9 near the limiting tube 11. The outer diameter of the limiting ring 94 is adapted to the inner diameter of the limiting tube 11, and the limiting ring 94 is slidably embedded in the limiting tube 11.

[0063] Using the above technical solution, the limiting tube 11 and the upper limit ring 94 of the movable sleeve 9 cooperate to form a guide structure, ensuring that the movable sleeve 9 slides coaxially, avoiding deviation that could cause operational jamming, ensuring smooth disassembly and installation of the hose during cleaning, and at the same time limiting the range of motion of the movable sleeve 9 so that it cannot completely detach from the outside of the quick-release connector 6.

[0064] Both sides of the bottom end of the liquid storage box 5 are integrally formed with strip-shaped support bars 13, which extend along the length of the liquid storage box 5.

[0065] The top of the layered partition 4 is provided with a strip-shaped positioning groove 14 corresponding to the position of each support bar 13, and the support bar 13 can be slidably inserted into the positioning groove 14.

[0066] By adopting the above technical solution, the support strip 13 at the bottom of the liquid storage box 5 is adapted to the positioning groove 14 at the top of the layered partition 4, which not only allows the liquid storage box 5 to be quickly positioned on the layered partition 4 without repeated adjustments, but also restricts the liquid storage box 5 from moving horizontally, preventing the liquid storage box 5 from shifting during equipment operation or maintenance. At the same time, the liquid storage box 5 can be smoothly pulled out along the positioning groove 14 during subsequent cleaning, improving the convenience of operation and cleaning.

[0067] Multiple arc-shaped guide grooves 15 are spaced apart at the top of the layered partition 4 along its length. Multiple arc-shaped rings 16 are fixedly installed above each arc-shaped guide groove 15 along its length. The arc-shaped opening of the arc-shaped ring 16 faces the arc-shaped guide groove 15, and the arc-shaped ring 16 and the arc-shaped guide groove 15 enclose and form a limiting channel for the liquid guiding hose 7 to pass through.

[0068] Using the above technical solution, a limiting channel is constructed through the arc-shaped guide groove 15 and the arc-shaped ring 16 to achieve the orderly arrangement of the liquid guiding hose 7. The limiting channel enclosed by the arc-shaped guide groove 15 and the arc-shaped ring 16 fixes the liquid guiding hose 7, avoids messy tangling, keeps the inside of the equipment neat, and makes it easy for operators to identify the hose corresponding to the liquid storage box 5 and the peristaltic pump 8, reducing misoperation during cleaning and maintenance.

[0069] Rectangular notches 18 are provided at both ends of the bottom of the layered partition 4. Multiple sets of pads 17 are fixedly installed at intervals along the vertical direction on both sides of the inner wall of the raw material storage cavity 3. Each set of pads 17 includes two pad units corresponding to the rectangular notches 18 on both sides of the layered partition 4. The rectangular notches 18 can be placed on the corresponding pad units.

[0070] Using the above technical solution, the layered partition 4 can be detachably installed by cooperating with the rectangular notch 18 and the pad 17. The rectangular notch 18 at the bottom of the layered partition 4 rests on the pad 17 on the inner wall of the raw material storage cavity 3, forming a detachable connection. Operators can easily remove the partition for easy cleaning of the upper and lower surfaces of the partition and the bottom of the storage cavity. The spaced pads 17 provide stable support for the partition without taking up too much space. Each pad corresponds to the notch on both sides of the partition, ensuring even force distribution and stable installation. The height of the partition can also be adjusted as needed, improving equipment flexibility. The detachable design allows for more thorough cleaning and meets hygiene requirements.

[0071] Multiple rectangular mounting plates are fixed at equal intervals along the vertical direction on the inner sidewall of the raw material storage cavity 3. The peristaltic pump 8 has mounting lugs integrally formed at the four corners of its housing, and the mounting lugs are fixed to the mounting plates by screws.

[0072] Using the above technical solution, the peristaltic pump 8 is securely installed by screws through the cooperation of the rectangular mounting plate on the inner wall of the raw material storage chamber 3 and the mounting lugs of the peristaltic pump 8 housing, which prevents the peristaltic pump 8 from vibrating and shifting during equipment operation; the peristaltic pump 8 can be quickly removed by removing the screws, which facilitates cleaning of the pump body and the inlet and outlet liquid ends.

[0073] Working principle:

[0074] Beverage ingredients are stored in a liquid storage box 5 on a layered partition 4 inside the raw material storage chamber 3. The peristaltic pump 8 draws ingredients from the liquid storage box 5 through a liquid guide hose 7 with quick-release connectors 6 at both ends, and completes the dispensing output through the liquid outlet cabinet 2. During installation, the limiting ball 62 of the quick-release connector 6 is locked into the annular groove of the liquid guide hose 7 for fixation. During cleaning, the movable sleeve 9 is pushed to make the limiting ball 62 enter the clearance cavity 92, so the liquid guide hose 7 can be removed. The liquid storage box 5 can be pulled out along the structure of the support bar 13 and the positioning groove 14. The layered partition 4 can be disassembled through the rectangular notch 18 and the pad 17. The peristaltic pump 8 can be removed from the mounting plate through the mounting lugs and screws, so that each component can be easily cleaned and maintained.

[0075] The basic conveying logic of the beverage mixing machine, the liquid extraction principle of the peristaltic pump, the liquid outlet pipeline of the liquid outlet cabinet and the installation of supporting valves and other related equipment and technologies are all existing technologies. This manual will not go into too much detail, but will focus on disclosing in detail the structural design of the equipment that improves the ease of cleaning.

[0076] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
