[0050] See Figures 1 to 7As shown, the present application provides a liquid dispensing head, which includes a main body 1000, a liquid dispenser 2000, and a weighing device 3000. The main body 1000 includes a head body 1100 and a body body 1200. The head body 1100 is arranged on the body body 1200, the liquid dispenser 2000 is arranged on the head body 1100, and the weighing device 3000 is arranged on the body body 1200. The weighing device 3000 is located directly below the liquid dispenser 2000. The "directly below" indicates that the relative position relationship between the weighing device 3000 and the liquid dispenser 2000 is the upper and lower relative position in the direction of gravity. This indicates that the weighing device 3000 is located directly below the liquid dispenser 2000, so that after the liquid is dispensed, the liquid dispenser 2000 can cause the beverage to fall along the direction of gravity and fall exactly onto the weighing device 3000. At this time, the disposable drinking cup can be placed on the weighing device 3000, and the weighing device 3000 is used as a reference for the placement position of the disposable drinking cup to initially locate the upper and lower relative positions of the disposable drinking cup and the liquid dispenser 2000 in the direction of gravity.

[0051] like Figure 4 As shown, the weighing device 3000 includes a cantilever element 3100, a weighing platform element 3200 and a positioning element 3300. One end of the cantilever element 3100 is connected to the main body 1200, and the weighing platform element 3200 is connected to the other end of the cantilever element 3100. The length of the cantilever element 3100 can be adjusted so that the weighing platform element 3200 located at the other end thereof can be opposite to the liquid dispenser 2000 in the direction of gravity. The weighing platform element 3200 has a load-bearing surface 3210, and the load-bearing surface 3210 faces the liquid dispenser 2000. The disposable drinking cup can be placed on the weighing surface of the weighing platform element 3200, thereby enabling the disposable drinking cup to be further accurately aligned with the liquid dispenser 2000 in the upper and lower directions.

[0052] Furthermore, a positioning element 3300 is disposed on the weighing platform 3200. The positioning element 3300 is used to define a liquid drop area 3220 on the load-bearing surface 3210 of the weighing platform 3200. The liquid drop area 3220 is aligned with the liquid dispenser 2000 in the direction of gravity. At this point, the operator can place the disposable drinking cup on the weighing platform 3200 of the weighing device 3000 and position it in the liquid drop area 3220 of the weighing platform 3200 using the positioning element 3300. After adjusting the length of the cantilever element 3100 and the positioning of the positioning element 3300, the liquid drop area 3220 is more accurately aligned with the liquid dispenser 2000 in the direction of gravity.

[0053] As can be seen, in the above structure, the scale 3000 is first used as a reference for the placement of the disposable drinking cup, initially determining the vertical relative position of the disposable drinking cup and the liquid dispenser 2000 in the direction of gravity. Furthermore, by adjusting the length of the cantilever element 3100, the scale element 3200 is aligned more precisely with the liquid dispenser 2000 in the direction of gravity, further ensuring the precise vertical alignment of the disposable drinking cup with the liquid dispenser 2000. Finally, the positioning element 3300 forms a drop area 3220 on the scale element 3200, allowing the disposable drinking cup to be precisely positioned relative to the liquid dispenser 2000 in the direction of gravity. Furthermore, the positioning element 3300 allows the operator to quickly position the disposable drinking cup in the drop area 3220, ensuring precise vertical alignment with the liquid dispenser 2000 while also increasing the speed of positioning and placement, thereby increasing the speed of dispensing.

[0054] In one embodiment, a liquid dispenser 2000 includes a device assembly housing 2100 and a fluid outlet assembly 2200. An internal cavity 2110 is defined within the device assembly housing 2100. A chamber window for the internal cavity 2110 is defined at the top of the device assembly housing 2100. A plurality of fluid assembly holes 2120 are defined at the bottom of the device assembly housing 2100. The device assembly housing 2100 can have various regular or irregular shapes, such as a cylinder, an elliptical cylinder, or a square cylinder, and is not limited thereto.

[0055] In one embodiment, the device assembly housing 2100 may include a housing sidewall plate and a housing bottom wall plate. The housing sidewall plate is a cylindrical plate having an axially extending inner cavity. The housing bottom wall plate is sealably mounted on the end of the housing sidewall plate. The housing sidewall plate and the housing bottom wall plate together enclose an inner cavity 2110 of the device assembly housing 2100. A plurality of fluid assembly holes 2120 are provided in the housing bottom wall plate. The fluid outlet assembly 2200 includes a plurality of fluid outlet pipes 2210, each of which is disposed within a fluid assembly hole 2120. The central axis of at least a portion of the fluid outlet pipes 2210 passes through the liquid drop area 3220 of the weighing platform element 3200.

[0056] The liquid outlet 2000 may also include a fluid delivery component and a fluid drive component. The fluid delivery component includes a plurality of fluid delivery tubes, and the number of fluid delivery tubes is configured to be the same as the number of fluid outlet tubes 2210. Each fluid delivery tube is connected to a fluid outlet tube 2210. The fluid drive component includes a plurality of drive pumps, each drive pump is connected to a fluid delivery tube, and is used to drive the flow of fluid in different fluid delivery tubes.

[0057] The positioning element 3300 can adopt various structures. For example, in one embodiment, the positioning element 3300 includes at least two positioning stops 3310. For example, the positioning stops 3310 can be provided in two, three, or more numbers. At least two positioning stops 3310 are provided on the load-bearing surface 3210 of the weighing platform element 3200. Each positioning stop 3310 has a limiting surface 3320. Therefore, the multiple positioning stops 3310 can cooperate with each other, and the limiting surfaces 3320 of different positioning stops 3310 can be used to limit contact with different positions of the beverage cup, thereby positioning the beverage cup in the liquid drop area 3220 of the weighing platform element 3200.

[0058] like Figure 4 As shown, in one embodiment, the cantilever element 3100 is a linear plate, and the weighing platform element 3200 is a circular plate. The thickness of the cantilever element 3100 is the same as that of the weighing platform element 3200. The end of the cantilever element 3100 is connected to the side of the weighing platform element 3200, and the cantilever element 3100 and the weighing platform element 3200 are configured as an integrally formed structure. The positioning element 3300 includes two positioning stops 3310. The positioning stops 3310 are plate-shaped. One end of the two positioning stops 3310 is connected, and the other ends of the two positioning stops 3310 are separated. There is an angle between the two positioning stops 3310, thereby constructing the following structure on the weighing platform element 3200 through the two positioning stops 3310. Figure 4 In the triangular limiting structure shown, the inner surface of each positioning stopper 3310 is used to form a limiting surface 3320 , and the two positioning stops 3310 are vertically arranged on the load-bearing surface 3210 of the weighing platform element 3200 and surround the liquid falling area 3220 of the weighing platform element 3200 .

[0059] In addition, the liquid drop area 3220 of the weighing platform element 3200 is provided with a plurality of liquid leakage hollow holes 3230, which can be as follows: Figure 4 As shown, the circular structure allows for the leakage of liquid from the dispenser 2000 onto the outside of the disposable drinking cup through the openings 3230, preventing it from remaining on the weighing device 3000. Furthermore, one end of the cantilever element 3100 is detachably connected to the main body 1200, allowing the weighing device 3000 to be removed from the main body 1200. This facilitates routine cleaning of the cantilever element 3100, the weighing platform 3200, and the positioning element 3300, ensuring food safety.

[0060] Moreover, since one end of the cantilever element 3100 can be detachably connected to the main body 1200, the connection height of the cantilever element 3100 can be adjusted on the main body 1200, thereby adjusting the height of the weighing device 3000. When the height difference between the weighing device 3000 and the liquid dispenser 2000 is determined, the height spacing between the load-bearing surface 3210 of the weighing platform element 3200 and the liquid outlet of the fluid outlet pipe 2210 can be determined. At the same time, the height specification of the disposable drinking cup is a fixed value. Therefore, it can be ensured that the difference between the height spacing between the load-bearing surface 3210 of the weighing platform element 3200 and the liquid outlet of the fluid outlet pipe 2210 and the height of the cup body of the drinking cup is between 210mm-220mm, which is within the height range suitable for the disposable drinking cup to receive drinks.

[0061] In addition to the mechanical structures such as the cantilever element 3100, the weighing platform element 3200 and the positioning element 3300, the weighing device 3000 also includes an electrical device capable of calculating the flow rate. For example, in one embodiment, the weighing device 3000 includes a flow rate calculation unit 4000, which is arranged in the main body 1000. The calculation principle of the flow rate calculation unit 4000 is to calculate the total amount of liquid discharged by the liquid dispenser 2000 using weight data and time data. For example, the flow rate calculation unit 4000 is connected to the cantilever element 3100. 00 is connected to the liquid dispenser 2000, and the flow rate calculation unit 4000 is used to obtain weight data borne by the cantilever element 3100 and time data of liquid discharge from the liquid dispenser 2000. The weight data represents the weight data borne by the disposable drinking cup after the weight of the disposable drinking cup is removed and the entire amount of liquid discharged from the liquid dispenser 2000 is received. When the time data of liquid discharge from the liquid dispenser 2000 is also obtained, the flow rate calculation unit 4000 can calculate the flow rate of the fluid discharged from the liquid dispenser 2000 based on the weight data and time data.

[0062] The specific calculation formula is: fluid flow rate = weight data / time data x water density. It should be noted that the fluid flow rate is temporarily estimated based on the density of water, so there is a certain degree of error in the fluid flow rate.

[0063] like Figure 7 As shown, in one embodiment, the flow rate calculation unit 4000 includes a weight detection device 4100, a time measurement device 4200, and a data calculation device 4300. The weight detection device 4100 is disposed in a body cavity of the fuselage main body 1200. The fuselage main body 1200 has an assembly hole, and one end of the cantilever element 3100 is assembled in the body cavity of the fuselage main body 1200 through the assembly hole. The weight detection device 4100 is connected to the cantilever element 3100 in the body cavity of the fuselage main body 1200 to obtain weight data borne by the cantilever element 3100.

[0064] A time measurement device 4200 is disposed within the head chamber of the handpiece body 1100 and is connected to the liquid dispenser 2000. Time measurement device 4200 is used to obtain time data for liquid discharge from the liquid dispenser 2000. Time data represents the duration elapsed from the start of liquid discharge to the end of liquid discharge from the liquid dispenser 2000. A data calculation device 4300 is disposed within the body chamber of the main body 1200 and is connected to the weight detection device 4100 and the time measurement device 4200. Data calculation device 4300 is used to obtain weight data and time data, and to calculate the flow rate of the fluid discharged from the liquid dispenser 2000 based on the weight and time data.

[0065] When using the time data acquired by the time measurement device 4200 to calculate the fluid flow rate, one approach is to first issue a fixed-time liquid discharge instruction and then obtain the weight data of the discharged liquid within that fixed time. The fluid flow rate calculation formula is: fluid flow rate = weight data / time data x water density. In this case, the time data represents the fixed time, and the weight data also represents the weight of the liquid discharged within that fixed time.

[0066] Alternatively, multiple liquid discharge instructions can be issued at different fixed times, and then the weight data of the discharged liquid can be obtained at each fixed time. In this case, the weight data at each fixed time can be weighed to calculate the different fluid flow rates at each fixed time, ensuring accurate discharge of the liquid volume at each fixed time. In this method, the formula for calculating the fluid flow rate is also: fluid flow rate = weight data / time data x water density. In this case, the time data represents each different fixed time issued, and the weight data also represents the weight data of the liquid volume discharged at each different fixed time.

[0067] In short, the time data can be a fixed time or different fixed times, and the weight data can be the weight data obtained at each fixed time. Those skilled in the art can select an appropriate calculation method according to actual needs, and this is not limited here.

[0068] In addition, the flow rate calculation unit 4000 may also include a revolution metering device, which is used to obtain data on the number of revolutions of the driving pump, calculate the actual amount of liquid discharged when the number of revolutions of the driving pump is one revolution, and then calculate the number of revolutions of the driving pump based on the required amount of liquid discharged during the discharge process. In this calculation method, the revolution metering device obtains data on the number of revolutions of the driving pump, and similarly to the above, the weight detection device 4100 is used to obtain data on the weight borne by the cantilever element 3100, thereby obtaining data on the weight of the total amount of liquid discharged during the operation of the driving pump.

[0069] The calculation formula for the single-turn liquid output is: single-turn liquid output = weight data / number of rotations data.

[0070] At this time, after obtaining the single-turn liquid discharge volume of the driving pump, the number of rotation circles of the driving pump can be calculated according to the liquid discharge volume requirement during liquid discharge, thereby achieving accurate liquid discharge.

[0071] To perform the actual calculation, you can first issue a command for a fixed number of rotations for one or more pumps, and then weigh the actual liquid output during that fixed number of rotations. The formula for calculating the single-turn output is: Single-turn output = Weight data / Number of rotations data. In this case, the number of rotations data represents the fixed number of rotations, and the weight data represents the actual liquid output during that fixed number of rotations.

[0072] On this basis, the flow rate calculation unit 4000 can further obtain unit density data of different materials to accurately calculate the fluid flow rate. For example, in one embodiment, the flow rate calculation unit 4000 includes a density acquisition device 4400. The density acquisition device 4400 is disposed in the head chamber of the head body 1100 and is connected to the liquid outlet 2000. The density acquisition device 4400 is used to obtain a plurality of unit density data of different materials flowing out of the liquid outlet 2000. Among them, the density acquisition device 4400 can directly detect the density of the material flowing out of the liquid dispenser 2000, or the density acquisition device 4400 can also indirectly judge the density of the material by judging that different materials flow out of the corresponding fluid outlet pipe 2210 based on the pre-measured density of different materials. For example, the type of material discharged from each fluid outlet pipe 2210 is fixed. As long as the density acquisition device 4400 judges the fluid outlet pipe 2210 from which the material flows out, it can directly obtain the density of the material flowing out of the fluid outlet pipe 2210 based on the data obtained in advance.

[0073] In addition, the weight detection device 4100 is used to obtain unit weight data borne by the cantilever element 3100 when different materials flow out of the liquid dispenser 2000. The time measurement device 4200 is used to obtain unit time data for different materials flowing out of the liquid dispenser 2000. The unit time data is the duration from the start to the end of the discharge of a single material by the liquid dispenser 2000. The data calculation device 4300 is used to obtain unit weight data, unit time data, and unit density data, and calculate the fluid flow rate of the liquid discharged by the liquid dispenser 2000 based on the unit weight data, unit time data, and unit density data.

[0074] As can be seen, when different materials are sequentially and individually discharged from the liquid dispenser 2000, the weight detection device 4100 can obtain a number of unit weight data borne by the cantilever element 3100 during the discharge of the different materials. These unit weight data represent the weights of the different materials discharged. The time measurement device 4200 can also obtain a number of unit time data during the discharge of the different materials. The unit time data represents the duration from the start to the end of the discharge of the single material by the liquid dispenser 2000.

[0075] The calculation formula is: Fluid flow rate for each material = unit weight data / unit time data x unit density data. Fluid flow rate = fluid flow rate for each material / n, where n is the number of material types.

[0076] In addition, after obtaining the fluid flow rate, the liquid output of the liquid dispenser 2000 can be reversely calculated using the above formula, rather than using the scale 3000 to obtain the liquid output of the liquid dispenser 2000. This is because the scale 3000 obtains the liquid output of the liquid dispenser 2000 after the liquid has been discharged. If the liquid dispenser 2000 discharges too much liquid, it will easily cause the disposable drinking cup to fill up and overflow. However, obtaining the liquid output of the liquid dispenser 2000 based on the fluid flow rate is to actively calculate the liquid output while the liquid dispenser 2000 is discharging liquid. When the liquid output reaches a preset range, a warning can be issued in a certain manner, and the liquid dispensing operation of the liquid dispenser 2000 can be actively suspended to prevent excessive liquid output and overflow of the disposable drinking cup.

[0077] For example, in one embodiment, the flow rate calculation unit 4000 includes a liquid discharge warning device 4500, which is disposed within the body cavity of the main body 1200 and is connected to a data calculation device 4300. The data calculation device 4300 is further configured to calculate the real-time total liquid discharge based on the fluid flow rate. The liquid discharge warning device 4500 is configured to obtain the real-time total liquid discharge and generate liquid discharge alarm information based on the real-time total liquid discharge and a preset total liquid discharge. The liquid discharge alarm information may include various forms such as an audible alarm, a light signal alarm, and a vibration alarm.
