Description

Technical Field

[0001] The present invention relates to the field of liquid discharging equipment, and particularly to a weighing and splash-proof device for a liquid discharging equipment. Background Art

[0002] In recent years, in the catering industries such as milk tea, coffee, and bars, a liquid discharging machine has emerged. This liquid discharging machine is provided with a plurality of different containers, and each container contains a different liquid beverage. When in use, according to requirements, these beverages are pumped to the liquid discharging head by different pumps and flow into the cup below the liquid discharging head.

[0003] When the traditional liquid discharging machine receives the beverage, the staff first places the cup on the tray below the liquid discharging head, and the liquid discharging head discharges the corresponding beverage according to the input instruction of the staff. In the above working process, due to the large height difference between the liquid discharging head and the cup, when the liquid falls, on the one hand, it will generate a large noise, and on the other hand, it will splash everywhere, affecting the environmental hygiene of the liquid discharging machine. The staff needs to frequently wipe the splashed beverage clean, increasing the workload.

[0004] In addition, during the actual working process, occasionally there will be a situation where the staff forgets to place an empty cup on the tray. Once this problem occurs, the beverage flowing out of the liquid discharging head will directly spill onto the working surface of the liquid discharging machine, causing waste on the one hand and increasing the workload of the staff on the other hand.

[0005] Therefore, there is a need for a method or device that can solve the above problems now. Summary of the Invention

[0006] The present invention is to solve the above-mentioned deficiencies existing in the prior art, and proposes a device with a simple structure, ingenious design, reasonable layout, which can automatically detect the mass of the received liquid and prevent the liquid from splashing during the receiving process.

[0007] The technical solution of the present invention is: a weighing and splash-proof device for a liquid discharging equipment, including a liquid discharging equipment body 1, and a liquid discharging head assembly 2 is arranged on the liquid discharging equipment body 1. It is characterized in that: a cup holder assembly is arranged on the liquid discharging equipment body 1 below the liquid discharging head assembly, and a barcode scanner 3 is arranged above the liquid discharging head assembly. The cup holder assembly includes a lifting mechanism 4 located inside the liquid discharge device body 1, a pair of symmetrically distributed support frames 5 are connected to the working end of the lifting mechanism 4, a support shaft 9 is arranged between the two support frames 5, a support chassis 10 is rotatably connected to the support shaft 9, a weighing sensor 11 is arranged on the support chassis 10, and the weighing sensor 11 is connected to the bottom end surface of the scale pan 12, the cup holder assembly also includes a cup holder shell 8, the cup holder shell 8 is coated outside the support shaft 9 and the support chassis 10, and a limit baffle 6 is fixedly connected between the two support frames 5, and when the cup holder shell 8 is in a horizontal state, its rear end surface contacts the limit baffle 6, The liquid outlet device body 1 is provided with an infrared sensor 13 , and the infrared sensor 13 is located at the rear of the outlet of the liquid outlet head assembly 2 .

[0008] A sealing strip 14 is arranged in the clearance groove 7 .

[0009] The cross section of the sealing strip 14 is an isosceles triangle. The sealing strip 14 is connected to the edge of the clearance groove 7 through the mounting groove 15 provided thereon. In the absence of interference from the support frame 5, the edges of the two sealing strips 14 overlap each other.

[0010] An annular cup holder 16 is provided to match the weighing pan 12 . A limiting step is provided at the bottom of the inner wall of the annular cup holder 16 . The inner wall of the limiting step matches the outer edge of the weighing pan 12 .

First of all, the cup holder assembly for carrying the cup can change its height under the action of the lifting mechanism. Combined with the operation of scanning code recognition, it can automatically realize the lifting action according to the specifications of the cup itself, so as to ensure that the cup mouth of each specification of the cup is closely attached to the liquid discharging head assembly when receiving liquid, which can effectively prevent liquid splashing. And it also sets a cup cover connected by magnetic force at the liquid discharging port, which can further prevent liquid splashing. It uses a weighing sensor and an infrared sensor to sense different states of the cup body, realizes automatic recognition and automatic action.

[0024] A sealing strip 14 is arranged in the clearance groove 7 .

[0025] The cross section of the sealing strip 14 is an isosceles triangle. The sealing strip 14 is connected to the edge of the clearance groove 7 through the mounting groove 15 provided thereon. In the absence of interference from the support frame 5, the edges of the two sealing strips 14 overlap each other.

[0026] An annular cup holder 16 is provided to match the weighing pan 12 . A limiting step is provided at the bottom of the inner wall of the annular cup holder 16 . The inner wall of the limiting step matches the outer edge of the weighing pan 12 .

[0027] The liquid discharge head assembly 2 is matched with an anti-splash cup cover 17 , and a plurality of strong magnets 18 evenly distributed in the circumferential direction are arranged on the top surface of the anti-splash cup cover 17 . The anti-splash cup cover 17 can be adsorbed on the liquid discharge device body 1 through the strong magnets 18 .

[0028] Two limiting holes 19 are provided on the support frame 5, and a limiting mechanism is provided on the side wall of the support chassis 10. The limiting mechanism includes a limiting ball 21 matching the limiting hole 19. The limiting ball 21 is tightened by a spring. The limiting ball 21 and the spring are both arranged in a receiving hole opened in the side wall of the support chassis 10.

[0029] The lifting mechanism 4 is an electric push rod, a hydraulic cylinder or a pneumatic cylinder. The working process of the weighing and splash-proof device for the liquid discharge device of the embodiment of the present invention is as follows: in the initial state, the cup holder assembly is opened, that is, the supporting chassis 10 therein is in a horizontal state, and the splash-proof cup cover 17 is adsorbed on the liquid discharge device body 1 through a strong magnet 18, and it is located outside the liquid discharge head assembly 2. At the same time, the annular cup holder 16 is also placed on the scale pan 12, and the limiting step at the bottom of the inner wall thereof is stuck at the outer edge of the scale pan 12 to achieve positioning; According to the user's order information, the staff selects a cup 20 of the appropriate specification, and uses the barcode scanner 3 to scan the barcode on the surface of the cup 20. The control system determines what specification the current cup 20 is (large cup, medium cup, small cup), and then places the cup 20 on the weighing pan 12. The annular cup holder 12 is located outside the bottom of the cup 20, which can prevent the cup 20 from tipping over. After the cup 20 is placed in place, after the weighing sensor 11 detects a change in mass, it sends a signal to the control system; The control system inputs instructions according to the barcode order information and selects the required beverage type; After the control system receives the signal sent by the weighing sensor 11, it will first control the lifting mechanism 4 to work. The lifting mechanism 4 drives the cup holder bracket 6 to rise, and then 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 controls the lifting mechanism 4 to stop working, and the cup 20 stays at the current height; at this time, the cup mouth part of the cup 20 is located inside the anti-splash cup cover 17; at the same time, the control system will also control the corresponding pump body in the liquid outlet device to work, extract the corresponding type of beverage from the liquid storage container of the liquid outlet device, and flow out through the liquid outlet head assembly 2 into the cup 20 to achieve liquid outlet. During the liquid outlet process, on the one hand, the height difference between the cup 20 and the liquid outlet has been minimized, and on the other hand, the anti-splash cup cover 17 is provided at the cup mouth, so the phenomenon of liquid splashing can be prevented to the greatest extent; As the liquid outlet operation progresses, 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 reaches the corresponding preset value, the control system controls the pump body to stop working, and at the same time controls the lifting mechanism 4 to act in the reverse direction, driving the cup 20 to descend. After the cup 20 returns to the initial height, its top completely disengages from the anti-splash cup cover 17, and the staff removes the cup 20 from the weighing pan 12, thus completing a complete liquid outlet process; When the liquid outlet device needs to be cleaned, the support base plate 10 can be manually pulled to change its state from horizontal to vertical (the annular cup holder 16 is removed in advance). In this state, there are no obstacles directly below the liquid outlet head assembly 2, and a large cleaning container can be placed here for convenient cleaning operations; When the support base plate 10 is in a horizontal posture, the rear end surface of the cup holder housing 8 contacts the limit baffle 6 at this time, that is, the cup holder housing 8 (and the cup 20 thereon) is supported by the limit baffle 6. At the same time, the limit ball 21 in the limit mechanism is stuck in a limit hole 19 on the support frame 5. When the support base plate 10 is in a vertical posture, the limit ball 21 is stuck in another limit hole 19. The limit ball 21 presses the limit hole 19 under the action of the spring. When unlocking, the staff needs to manually pull the support base plate 10 in the reverse direction, the spring compresses, so that it disengages from the current limit hole 19, and after rotating a certain angle, it falls into another limit hole 19 again, completing the angle switching of the support base plate 10.

[0030] In order to prevent liquid from splashing into the interior of the liquid outlet device body 1 from the relief groove 7 during the working process, two symmetrically distributed sealing strips 14 are also provided at the relief groove 7. The cross-section of the sealing strip 14 is an isosceles triangle. The advantage of this structure with one side large (thick) and the other side small (thin) is that the connection between the sealing strip 14 and the liquid outlet device body 1 is realized by using the installation groove 15 provided on the thicker side, while the thinner side can be elastically deformed more easily, so as to adapt to the movement of the support frame 5. When the support frame 5 moves in the relief groove 7, it can easily deform the part of the sealing strip 14 in contact with it, and will not hinder the movement of the support frame 5. At the same time, the sealing strip 14 will fit on the surface of the support frame 5, thus ensuring the sealing effect.
