[0018] Figure 2 The diagram shown is an exploded view of the liquid metering device in the embodiment. Detailed Implementation

[0019] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0021] Reference Figure 1 and Figure 2This embodiment provides a liquid quantitative dispensing device (hereinafter referred to as quantitative dispensing device 100) for precise dispensing control, and is therefore suitable for quantitative addition of ingredients to liquid beverages such as milk tea and alcoholic beverages.

[0022] The quantitative dispensing device 100 of this embodiment includes a receiving platform 1 for holding a container 200 (i.e., a beverage ingredient tank or ingredient barrel), a conveying pipe 2, a controller 4, and four weighing sensor modules 3 disposed on the receiving platform 1. Of course, the container 200 contains liquid beverage ingredients or ingredients.

[0023] The material conveying pipeline 2 is provided with an inlet 21 for connecting to the container 200 and an outlet 22 for discharging the raw material in the container 200 at both ends. A valve 5 is installed between the inlet 21 and the outlet 22. Specifically, the valve 5 is a solenoid valve to control the flow and cut-off of the raw material in the material conveying pipeline 2.

[0024] The signal output terminal of the weighing sensor module 3 is connected to the signal input terminal of the controller 4, and the signal output terminal of the controller 4 is connected to the signal input terminal of the valve 5, so as to realize the real-time change of raw material in the container 200 through the weighing sensor module 3, and synchronously feed back the sensed information to the controller 4. Then, the controller 4 controls the opening and closing of the valve 5 so that the quantitative raw material in the container 200 flows through the feed inlet 21 and the valve 5 under its own gravity until it flows out of the discharge outlet 22. At this time, a beverage cup to be prepared is placed at the discharge outlet 22 so that the quantitative raw material flowing out of the discharge outlet 22 flows into the beverage cup.

[0025] In this embodiment, as Figure 1 As shown, the receiving platform 1 has a receiving cavity 11, and the two ends of the conveying pipe 2 pass through the mounting holes in the top wall and front side wall of the receiving cavity 11, respectively; as Figure 2 The valve 5 shown is located inside the receiving cavity 11, and a power interface 9 for electrically connecting the controller 4 is provided on the rear side wall of the receiving cavity 11. At this time, the feed port 21 is located outside the top of the receiving platform 1, and the discharge port 22 is located outside the front side wall of the receiving platform 1.

[0026] like Figure 2 As shown, each weighing sensor module 3 includes a U-shaped mounting base 31, foot pads 32 disposed at the bottom of the mounting base 31, and a gravity sensor 33 disposed within the foot pads 32. Each mounting base 31 is assembled at one of the four corners of the receiving cavity 11. Each foot pad 32 passes through a through hole in the bottom wall of the receiving cavity 11 facing the ground to form four support ends for overall support, thereby forming a stable support. The signal output end of the gravity sensor 33 is the signal output end of the weighing sensor module 3.

[0027] In practice, the container 200 containing the raw materials is first placed on the top of the support platform 1. Then, the outlet of the container 200 is connected to the inlet 21 through a conduit. After that, the controller 4 coordinates the cooperation between the gravity sensor 33 and the valve 5 to achieve precise control of the quantitative discharge of the raw materials.

[0028] In summary, the weighing sensor module 3 is used to sense the real-time changes in the amount of liquid in the container 200, so as to feed back the sensed information to the controller 4. The controller 4 then controls the opening and closing of the valve 5 to ensure that the quantitative liquid in the container 200 flows through the inlet 21 and the valve 5 under its own gravity until it flows out of the outlet 22, thus completing the dispensing. This can replace the manual measurement of the dispensing amount with a measuring cup, so as to accurately dispense the liquid in the container 200, and the operation is convenient and efficient.

[0029] In addition, when the quantitative dispensing device 100 of this embodiment is applied to scenarios such as milk tea shops, it can ensure that the taste of each cup of beverage remains consistent by precisely controlling the dispensing amount or cup dispensing amount of each batch of raw materials.

[0030] Of course, in other embodiments, the number of weighing sensor modules 3 can also be 3 or 5 or more, which will not be described in detail here.

[0031] Furthermore, when there is only one or two gravity sensors 33, the gravity sensors 33 are placed on the support platform 1 and form surface support or surface contact to weigh the remaining raw material in the container 200 on the support platform 1.

[0032] In another preferred embodiment, such as Figure 2 As shown, the material conveying pipe 2 is equipped with a pump motor 6 for increasing the flow rate of raw materials, and the signal input terminal of the pump motor 6 is connected to the signal output terminal of the controller 4.

[0033] More specifically, in this embodiment, the pump motor 6 is a straight-through type, and when the gravity flow velocity of the raw material is low, the pump motor 6 can be turned on by the controller 4, thereby increasing the flow velocity of the raw material in the conveying pipe 2. Of course, in other embodiments, the pump motor 6 is an optional accessory, that is, the pump motor 6 can be replaced by a conveying pipe, in which case the conveying pipe is part of the conveying pipe 2.

[0034] Further preferred, such as Figure 1 and Figure 2As shown, a barcode scanner 8 is installed on the serving platform 1. The signal output terminal of the barcode scanner 8 is connected to the signal input terminal of the controller 4 to transmit the information scanned and identified by the barcode scanner 8 to the controller 4. For example, the outer wall of the beverage cup has a QR code (or barcode) label with a preset amount of raw materials or cup size. When in use, the barcode scanner 8 can first identify the QR code label on the beverage cup. The barcode scanner 8 will then transmit the cup size information identified from the QR code label to the controller 4 to ensure that the controller 4 will automatically dispense the cup in a measured quantity according to the cup size on the QR code and under its internal control program, thus effectively increasing the cup dispensing efficiency.

[0035] Further preferred, such as Figure 2 As shown, a rechargeable battery 7 for power supply is installed in the receiving cavity 11 of the receiving platform 1 to ensure that the quantitative dispensing device 100 can be used normally without an external power source, such as in outdoor applications. Of course, in other embodiments, the rechargeable battery 7 can be omitted, and only the power interface 9 is needed to ensure power supply to the controller 4, which in turn provides power support to the gravity sensor 33, the barcode scanner 8, the pump motor 6, and the valve 5.

[0036] Further preferred, such as Figure 1 and Figure 2 As shown, the top of the receiving platform 1 is provided with an anti-slip pad 10 to prevent the container 200 from sliding, and the controller 4 is also provided with an alarm to indicate that the container 200 is low on material.

[0037] In this specific embodiment, the support platform 1 includes a bottom cover 13 and a hollow main housing 12. The bottom cover 13 covers the opening of the main housing 12 and together form a receiving cavity 11. The mounting base 31 is assembled on the main housing 12. The foot pads 32 on the bottom of the mounting base 31 facing away from the main housing 12 pass through the through holes of the bottom cover 13 to support the whole consisting of the quantitative discharging device 100 and the container 200. At the same time, the gravity sensor 33 transmits the gravity signal of the whole to the controller 4 in real time.

[0038] Before the beverage is dispensed, the container 200 is placed on the anti-slip mat 10 on the top of the support platform 1. Then, the outlet of the container 200 is connected to the inlet 21 through a conduit to complete the installation of the container 200 on the metering dispensing device 100.

[0039] When ingredients need to be added to a beverage cup, the barcode scanner 8 first identifies the QR code label on the beverage cup and transmits it to the controller 4. Then, the controller 4, according to its preset control program, first controls the valve 5 and the pump motor 6 to open. At this time, the ingredients in the container 200 flow naturally into the inlet 21 under its own gravity, and then flow through the inlet 21, valve 5 and pump motor 6 in sequence until they flow out from the outlet 22. During the discharge process, the gravity sensor 33 will detect the weight of the remaining ingredients in the container 200 in real time, and calculate the weight of the discharged ingredients flowing out of the outlet 22 with the help of the control program of the controller 4. When the actual discharged weight is equal to the set discharged weight, the gravity sensor 33 will send a signal in time and feed it back to the controller 4, thereby controlling the valve 5 and the pump motor 6 to close, ultimately achieving precise quantitative addition of ingredients to each batch of beverage cups.

[0040] The control program of controller 4 is also set with a material shortage alarm value. When the gravity sensor 33 detects that the remaining weight of the raw material in container 200 is less than the material shortage alarm value, the alarm sound can be emitted through the alarm of controller 4 to inform the user to replenish the material in container 200 in time.

[0041] Of course, in other embodiments, a material shortage warning can also be displayed on the screen of the controller 4 to remind the user to replenish the material in time.

[0042] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
