Description

Technical Field

[0001] This utility model relates to the field of liquid dispensing equipment, and in particular to a weighing and splash-proof device for liquid dispensing equipment. Background Technology

[0002] In recent years, a type of liquid dispensing machine has emerged in the food and beverage industry, including milk tea, coffee, and bars. This machine contains multiple different containers, each filled with a different liquid beverage. When in use, different pumps are used to pump these beverages to the dispensing head, where they flow into a cup below the dispensing head.

[0003] Traditional dispensing machines require staff to place the cup on a tray below the dispensing head when dispensing beverages. The dispensing head then dispenses the corresponding beverage according to the staff's input instructions. During this process, due to the significant height difference between the dispensing head and the cup, the liquid falling causes considerable noise and splashing, affecting the cleanliness of the dispensing machine and requiring staff to frequently wipe up the spilled beverages, thus increasing their workload.

[0004] In addition, during actual operation, staff sometimes forget to place empty cups on the tray. When this happens, the beverage flowing from the dispensing head will spill directly onto the dispensing machine's work surface, causing waste and increasing the workload of the staff.

[0005] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention

[0006] The present invention addresses the aforementioned shortcomings of the existing technology by proposing a device with a simple structure, ingenious design, reasonable layout, capable of automatically detecting the quality of the liquid being received, and preventing liquid splashing during the receiving process.

[0007] The technical solution of this utility model is: a weighing and splash-proof device for liquid dispensing equipment, including a liquid dispensing equipment body 1, on which a liquid dispensing head assembly 2 is provided, characterized in that: a cup holder assembly located below the liquid dispensing head assembly 2 and a barcode scanner 3 located above the liquid dispensing head assembly 2 are provided on the liquid dispensing equipment body 1.

[0008] The cup holder assembly includes a lifting mechanism 4 located inside the liquid dispensing device body 1. The working end of the lifting mechanism 4 is connected to a pair of symmetrically distributed support frames 5. A support shaft 9 is disposed between the two support frames 5, and a support base 10 is rotatably connected to the support shaft 9. A weighing sensor 11 is disposed on the support base 10 and is connected to the bottom surface of the weighing pan 12. The cup holder assembly also includes a cup holder housing 8, which covers the support shaft 9 and the support base 10. A limit baffle 6 is fixedly connected between the two support frames 5. When the cup holder housing 8 is in a horizontal state, its rear end face contacts the limit baffle 6.

[0009] An infrared sensor 13 is provided on the body 1 of the liquid dispensing device, and the infrared sensor 13 is located at the rear of the outlet of the liquid dispensing head assembly 2.

[0010] A sealing strip 14 is provided in the relief groove 7.

[0011] The sealing strip 14 has an isosceles triangle cross section. The sealing strip 14 is connected to the edge of the relief groove 7 through the mounting groove 15 opened on it. In the absence of interference from the support frame 5, the edges of the two sealing strips 14 overlap each other.

[0012] A ring-shaped cup holder 16 is provided to match the weighing pan 12. The bottom of the inner wall of the ring-shaped cup holder 16 is provided with a limiting step, and the inner wall of the limiting step matches the outer edge of the weighing pan 12.

[0013] A splash guard 17 is provided in conjunction with the liquid outlet head assembly 2. The top surface of the splash guard 17 is provided with a plurality of strong magnets 18 evenly distributed in the circumferential direction. The splash guard 17 can be attracted to the liquid outlet device body 1 by the strong magnets 18.

[0014] The support frame 5 is provided with two limiting holes 19, and the side wall of the support chassis 10 is provided with a limiting mechanism. The limiting mechanism includes a limiting ball 21 that matches the limiting hole 19. The limiting ball 21 is pressed by a spring. The limiting ball 21 and the spring are both provided in the receiving hole opened in the side wall of the support chassis 10.

[0015] The lifting mechanism 4 is an electric push rod, a hydraulic cylinder, or a pneumatic cylinder.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This type of liquid dispensing device, featuring a weighing and splash-proof mechanism, boasts a simple structure, ingenious design, and rational layout. Addressing the problems inherent in traditional liquid dispensing devices, it employs a unique structure. Firstly, the cup holder assembly, supporting the cups, can adjust its height using a lifting mechanism. Combined with barcode scanning, it automatically adjusts its height according to the cup's dimensions, ensuring that the rim of each cup fits snugly against the dispensing head assembly when dispensing liquid, effectively preventing splashing. Furthermore, a magnetically connected cup cover at the dispensing outlet further prevents splashing.

[0018] It uses weighing sensors and infrared sensors to sense different states of the cup, enabling automatic identification and automatic action. Staff do not need to perform any other actions besides scanning the code, which can effectively reduce the workload of staff and thus improve overall work efficiency.

[0019] Furthermore, this device has a simple manufacturing process and low production cost, so it can be said to have many advantages and is particularly suitable for promotion and application in this field, with a very broad market prospect. Attached Figure Description

[0027] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. Figures 1 to 7 As shown: A weighing and splash-proof device for a liquid dispensing device includes a liquid dispensing device body 1, a liquid dispensing head assembly 2 disposed on the liquid dispensing device body 1, a cup holder assembly located below the liquid dispensing head assembly 2 disposed on the liquid dispensing device body 1, and a barcode scanner 3 located above the liquid dispensing head assembly 2.

[0028] The cup holder assembly includes a lifting mechanism 4 located inside the liquid dispensing device body 1. The working end of the lifting mechanism 4 is connected to a pair of symmetrically distributed support frames 5. A support shaft 9 is disposed between the two support frames 5, and a support base 10 is rotatably connected to the support shaft 9. A weighing sensor 11 is disposed on the support base 10, and the weighing sensor 11 is connected to the bottom end face of the weighing pan 12. The cup holder assembly also includes a cup holder housing 8, which covers the support shaft 9 and the support base 10 (the weighing sensor 11 is connected to the weighing pan 12 through a through hole in the cup holder housing 8). A limit baffle 6 is also fixedly connected between the two support frames 5. When the cup holder housing 8 is in a horizontal state, its rear end face contacts the limit baffle 6.

[0029] An infrared sensor 13 is provided on the body 1 of the liquid dispensing device, and the infrared sensor 13 is located at the rear of the outlet of the liquid dispensing head assembly 2.

[0030] A sealing strip 14 is provided in the relief groove 7.

[0031] The sealing strip 14 has an isosceles triangle cross section. The sealing strip 14 is connected to the edge of the relief groove 7 through the mounting groove 15 opened on it. In the absence of interference from the support frame 5, the edges of the two sealing strips 14 overlap each other.

[0032] A ring-shaped cup holder 16 is provided to match the weighing pan 12. The bottom of the inner wall of the ring-shaped cup holder 16 is provided with a limiting step, and the inner wall of the limiting step matches the outer edge of the weighing pan 12.

[0033] A splash guard 17 is provided in conjunction with the liquid outlet head assembly 2. The top surface of the splash guard 17 is provided with a plurality of strong magnets 18 evenly distributed in the circumferential direction. The splash guard 17 can be attracted to the liquid outlet device body 1 by the strong magnets 18.

[0034] The support frame 5 is provided with two limiting holes 19, and the side wall of the support chassis 10 is provided with a limiting mechanism. The limiting mechanism includes a limiting ball 21 that matches the limiting hole 19. The limiting ball 21 is pressed by a spring. The limiting ball 21 and the spring are both provided in the receiving hole opened in the side wall of the support chassis 10.

[0035] The lifting mechanism 4 is an electric push rod, a hydraulic cylinder, or a pneumatic cylinder.

[0036] The working process of the weighing and anti-splash device for the liquid dispensing equipment in this embodiment of the utility model is as follows: In the initial state, the cup holder assembly is opened, that is, the supporting base 10 is in a horizontal state, and the anti-splash cup cover 17 is attracted to the liquid dispensing equipment body 1 by a strong magnet 18. It is located outside the liquid dispensing head assembly 2. At the same time, the annular cup holder 16 is also placed on the weighing pan 12, and the limiting step at the bottom of its inner wall is stuck at the outer edge of the weighing pan 12 to achieve positioning.

[0037] According to the user's order information, the staff selects a cup 20 of appropriate size and scans the barcode on the surface of the cup 20 using the barcode scanner 3. The control system determines the size of the cup 20 (large, medium, or small). Then, the cup 20 is placed on the weighing pan 12. The ring cup holder 12 is located on the outside of the bottom of the cup 20 to prevent the cup 20 from tipping over. After the cup 20 is placed in place, the weighing sensor 11 detects the change in mass and sends a signal to the control system.

[0038] The control system inputs instructions based on the barcode order information and selects the desired beverage type;

[0039] After receiving the signal from the weighing sensor 11, the control system first controls the lifting mechanism 4 to work. The lifting mechanism 4 drives the cup holder 6 to rise, which in turn drives the cup 20 to rise. When the top edge of the cup 20 rises to the same height as the infrared sensor 13, the infrared sensor 13 is triggered and sends a signal to the control system. The control system then controls the lifting mechanism 4 to stop working, and the cup 20 stops at the current height. At this time, the mouth of the cup 20 is located inside the anti-splash cup cover 17. At the same time, the control system also controls the corresponding pump in the liquid dispensing device to work, drawing the corresponding type of beverage from the liquid storage container of the liquid dispensing device and flowing it out into the cup 20 through the liquid dispensing head assembly 2 to achieve liquid dispensing. During the liquid dispensing process, on the one hand, the height difference between the cup 20 and the liquid dispensing port has been minimized as much as possible, and on the other hand, the anti-splash cup cover 17 is also provided at the mouth of the cup, so the phenomenon of liquid splashing can be prevented as much as possible.

[0040] As the dispensing action proceeds, the liquid in the cup 20 gradually increases. When the weighing sensor 11 detects that the total mass of the cup 20 and the beverage has reached the corresponding preset value, the control system controls the pump to stop working and simultaneously controls the lifting mechanism 4 to reverse, causing the cup 20 to descend. After the cup 20 returns to its initial height, its top is completely detached from the anti-splash cup cover 17. The staff removes the cup 20 from the weighing pan 12, thus completing a complete dispensing process.

[0041] When the liquid dispensing device needs to be cleaned, the support base plate 10 can be manually moved to change it from a horizontal state to a vertical state (the annular cup holder 16 should be removed beforehand). In this state, there are no obstacles directly below the liquid dispensing head assembly 2, and a large cleaning container can be placed here to facilitate the cleaning operation.

[0042] When the support base plate 10 is in a horizontal position, the rear end face of the cup holder housing 8 is in contact with the limiting baffle 6, that is, the limiting baffle 6 supports the cup holder housing 8 (and the cup 20 on it). At the same time, the limiting ball 21 in the limiting mechanism is locked in one limiting hole 19 on the support frame 5. When the support base plate 10 is in a vertical position, the limiting ball 21 is locked in another limiting hole 19. The limiting ball 21 presses the limiting hole 19 under the action of the spring. When unlocking, the operator needs to manually turn the support base plate 10 in the opposite direction. The spring is compressed, allowing it to disengage from the current limiting hole 19. After rotating a certain angle, it falls into another limiting hole 19, completing the switching of the angle of the support base plate 10.

[0043] To prevent liquid from splashing from the relief groove 7 into the interior of the liquid outlet device 1 during operation, two symmetrically distributed sealing strips 14 are also provided at the relief groove 7.

[0044] The cross-section of the sealing strip 14 is an isosceles triangle. The advantage of this structure, which is large (thick) on one side and small (thin) on the other side, is that the connection between the sealing strip 14 and the liquid outlet device body 1 is achieved by using the mounting groove 15 set on the thicker side, while the thinner side can more easily undergo elastic deformation to adapt to the movement of the support frame 5. When the support frame 5 moves in the relief groove 7, the part of the sealing strip 14 that is in contact with it can be easily deformed without hindering the movement of the support frame 5. At the same time, the sealing strip 14 will adhere to the surface of the support frame 5, thereby ensuring the sealing effect.
