[0002] Milk tea and similar flavored drinks are widely loved by consumers due to their good taste, and the market demand for these drinks is constantly increasing. A dispensing machine is used to make milk tea and similar flavored drinks, capable of preparing various types of milk tea drinks according to different orders. The prepared drinks flow out from the dispensing machine's dispenser. Operators need to place disposable beverage cups under the dispensing machine's dispenser to collect the drinks as they flow out.

[0046] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0050] See Figures 1 to 7As shown, this application provides a dispensing head, which includes a main body 1000, a dispensing device 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 disposed on the body body 1200, the dispensing device 2000 is disposed on the head body 1100, and the weighing device 3000 is disposed on the body body 1200. The weighing device 3000 is located directly below the dispensing device 2000. This "directly below" means that the relative position between the weighing device 3000 and the dispensing device 2000 is a vertical relative position in the direction of gravity. Therefore, the weighing device 3000 is located directly below the dispensing device 2000, so that after the dispensing device 2000 dispenses liquid, the beverage falls along the direction of gravity and lands directly on the weighing device 3000. At this point, the disposable beverage cup can be placed on the weighing device 3000. Using the weighing device 3000 as a reference for the placement of the disposable beverage cup, the relative positions of the disposable beverage cup and the dispensing device 2000 under gravity are initially determined.

[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 at its other end can be vertically aligned with the liquid dispenser 2000 in the direction of gravity. The weighing platform element 3200 has a load-bearing surface 3210 facing the liquid dispenser 2000. A disposable beverage cup can be placed on the weighing surface of the weighing platform element 3200, thereby enabling the disposable beverage cup to achieve further vertical and precise alignment with the liquid dispenser 2000.

[0052] Furthermore, a positioning element 3300 is disposed on the weighing platform element 3200. The positioning element 3300 defines a liquid-falling area 3220 on the load-bearing surface 3210 of the weighing platform element 3200. The liquid-falling area 3220 is aligned with the liquid dispenser 2000 in the direction of gravity. At this time, the operator can place a disposable beverage cup on the weighing platform element 3200 of the weighing device 300 and position it in the liquid-falling area 3220 of the weighing platform element 3200 by the positioning element 3300. This liquid-falling area 3220 is a more precise area aligned with the liquid dispenser 2000 in the direction of gravity after the length adjustment of the cantilever element 3100 and the positioning adjustment of the positioning element 3300.

[0053] Therefore, the above structure first uses the weighing device 3000 as a reference for the placement of the disposable beverage cup, initially positioning the relative vertical positions of the disposable beverage cup and the dispensing device 2000 in the direction of gravity. Based on this, by adjusting the length of the cantilever element 3100, the weighing platform element 3200 achieves a more precise vertical alignment with the dispensing device 2000 in the direction of gravity, allowing for further precise vertical alignment between the disposable beverage cup and the dispensing device 2000. Finally, the positioning element 3300 forms a liquid drop area 3220 on the weighing platform element 3200, allowing the disposable beverage cup to achieve final precise positioning with the dispensing device 2000 in the direction of gravity within this liquid drop area 3220. Furthermore, the operator can quickly position the disposable beverage cup in the liquid drop area 3220 using the positioning element 3300, ensuring precise vertical alignment with the dispensing device 2000 and increasing the speed of placement, thereby improving order processing speed.

[0054] In one embodiment, the liquid dispenser 2000 includes a device assembly housing 2100 and a fluid dispensing assembly 2200. The device assembly housing 2100 has an internal cavity space 2110, a chamber window for the internal cavity space 2110 is formed at the top of the device assembly housing 2100, and a plurality of fluid dispensing holes 2120 are formed at the bottom of the device assembly housing 2100. The device assembly housing 2100 can adopt various regular or irregular shapes such as cylindrical, elliptical, or square, and is not limited thereto.

[0055] In one embodiment, the device assembly housing 2100 may include a housing side wall plate and a housing bottom wall plate. The housing side wall plate is a cylindrical plate with an axially through-hole inside. The housing bottom wall plate is sealed and fitted to the end of the housing side wall plate. The housing side wall plate and the housing bottom wall plate together enclose the inner cavity space 2110 of the device assembly housing 2100. A plurality of fluid assembly holes 2120 are formed in the housing bottom wall plate. The fluid outlet assembly 2200 includes a plurality of fluid outlet pipes 2210. Each fluid outlet pipe 2210 passes through 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 assembly and a fluid drive assembly. The fluid delivery assembly includes a plurality of fluid delivery pipes, the number of which is configured to be the same as the number of fluid outlet pipes 2210. Each fluid delivery pipe is connected to a fluid outlet pipe 2210. The fluid drive assembly includes a plurality of drive pumps, each drive pump being connected to a fluid delivery pipe for driving fluid flow in different fluid delivery pipes.

[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, such as two, three, or more positioning stops 3310. At least two positioning stops 3310 are disposed on the load-bearing surface 3210 of the weighing platform element 3200. Each positioning stop 3310 has a limiting surface 3320. Therefore, several positioning stops 3310 can cooperate with each other, using the limiting surfaces 3320 of different positioning stops 3310 to limit the 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 straight plate, and the weighing platform element 3200 is a circular plate. The thickness of the cantilever element 3100 is the same as the thickness 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, which are plate-shaped. One end of the two positioning stops 3310 is connected, and the other end of the two positioning stops 3310 is separated. The two positioning stops 3310 have an included angle, thereby constructing a shape on the weighing platform element 3200 as shown by the two positioning stops 3310. Figure 4 The triangular limiting structure shown has an inner surface of each positioning stop 3310 used to form a limiting surface 3320. 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-falling area 3220 of the weighing platform element 3200 is provided with several leakage perforations 3230, which can be used as follows: Figure 4 As shown, the weighing device is constructed in a circular pattern. When liquid is dispensed from the dispenser 2000 and spills outside the disposable beverage cup, the leakage perforation 3230 can be used to drain the overflowing liquid, preventing it from remaining on the weighing device 3000. Furthermore, one end of the cantilever element 3100 can be detachably connected to the main body 1200, allowing the weighing device 3000 to be disassembled relative to the main body 1200. This facilitates routine cleaning of the cantilever element 3100, the weighing platform element 3200, and the positioning element 3300, ensuring food safety.

[0060] Furthermore, 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 distance 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 beverage cup is a fixed value. Therefore, it can be ensured that the height difference 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 beverage cup is between 210mm and 220mm, which is within the height range suitable for receiving beverages in the disposable beverage cup.

[0061] In addition to mechanical structures such as the cantilever element 3100, weighing platform element 3200, and positioning element 3300, the weighing device 3000 also includes electrical components capable of calculating flow rate. For example, in one embodiment, the weighing device 3000 includes a flow rate calculation unit 4000, which is disposed in the main body 1000. The calculation principle of the flow rate calculation unit 4000 is to calculate the total amount of liquid discharged from the liquid outlet 2000 using weight data and time data. For example, the flow rate calculation unit 4000 and the cantilever element 3100 are integrated. The flow rate calculation unit 4000 is connected to the liquid dispenser 2000. The flow rate calculation unit 4000 is used to obtain the weight data borne by the cantilever element 3100 and the time data of the liquid dispenser 2000. The weight data represents the weight data borne by the disposable beverage cup after removing the weight of the disposable beverage cup and holding all the liquid dispensed by the liquid dispenser 2000. When the time data of the liquid dispenser 2000 is obtained at the same time, the flow rate calculation unit 4000 can calculate the fluid flow rate of the liquid dispenser 2000 based on the weight data and time data.

[0062] The specific calculation formula is: Fluid velocity = Weight data / Time data x Density of water. It should be noted that the fluid velocity is temporarily estimated using the density of water; therefore, this fluid velocity may contain some degree of error.

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

[0064] A time measuring device 4200 is installed in the head cavity of the head body 1100. The time measuring device 4200 is connected to the liquid dispenser 2000 and is used to acquire the time data of liquid dispensing from the liquid dispenser 2000, which is the duration from the start to the end of liquid dispensing. A data calculation device 4300 is installed in the body cavity of the body 1200 and is connected to the weight detection device 4100 and the time measuring device 4200. The data calculation device 4300 is used to acquire weight data and time data, and calculate the fluid flow rate of the liquid dispensed from the liquid dispenser 2000 based on the weight data and time data.

[0065] When using the aforementioned time metering device 4200 to acquire time data and calculate fluid flow rate, one method is to first issue a discharge command for a fixed time, and then acquire the weight data of the discharged liquid within that fixed time. The formula for calculating fluid flow rate is: Fluid flow rate = Weight data / Time data x Density of water. In this case, the aforementioned time data represents the fixed time specified, and the weight data is also the weight of the discharged liquid within that fixed time.

[0066] In another approach, multiple dispensing commands for different fixed time periods can be issued, and the weight data of the dispensed liquid can be acquired at each fixed time. The weight data from different fixed time periods can then be weighed to calculate the different fluid flow rates within each fixed time period, ensuring the accuracy of the dispensing volume at each fixed time. In this approach, the formula for calculating the fluid flow rate is: Fluid flow rate = Weight data / Time data x Density of water. Here, the aforementioned time data represents each different fixed time period, and the weight data represents the weight of the dispensed liquid within each of these different fixed time periods.

[0067] In summary, the above time data can be based on a fixed time period or different fixed time periods, and the weight data is also selected from the weight data obtained within each fixed time period. Those skilled in the art can choose an appropriate calculation method according to actual needs, and no limitation is made here.

[0068] In addition, the flow rate calculation unit 4000 may also include a rotation count metering device. This device acquires the rotation count data of the drive pump, calculates the actual liquid output per rotation, and then calculates the rotation count based on the required output volume. In this calculation method, the rotation count metering device acquires the rotation count data of the drive pump. Similar to the previous method, the weight detection device 4100 acquires the weight data borne by the cantilever element 3100, thereby obtaining the total weight data of the liquid output during pump operation.

[0069] The formula for calculating the liquid output per revolution is: Liquid output per revolution = Weight data / Number of revolutions data.

[0070] At this point, after obtaining the liquid output per revolution of the drive pump, the number of revolutions of the drive pump can be calculated based on the required liquid output, thereby achieving precise liquid output.

[0071] In actual calculations, one or more drive pumps can be instructed to rotate a fixed number of times, and the actual liquid output within that fixed number of rotations can be weighed. The formula for calculating the liquid output per rotation is: Liquid output per rotation = Weight data / Number of rotations data. In this case, the aforementioned number of rotations data represents the fixed number of rotations, and the weight data represents the actual liquid output within that fixed number of rotations.

[0072] Based on this, the flow rate calculation unit 4000 can further acquire unit density data of different materials to perform accurate calculation of fluid flow rate. For example, in one embodiment, the flow rate calculation unit 4000 includes a density acquisition device 4400, which is disposed in the head cavity of the head body 1100 and connected to the liquid outlet 2000. The density acquisition device 4400 is used to acquire several unit density data of different materials flowing out of the liquid outlet 2000. The density acquisition device 4400 can directly detect the density of the material flowing out of the liquid outlet 2000. Alternatively, the density acquisition device 4400 can also indirectly determine the density of the material by judging the different materials flowing out of the corresponding fluid outlet pipe 2210 based on the pre-measured density of different materials. For example, the type of material flowing out of each fluid outlet pipe 2210 is determined. 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 pre-measured data.

[0073] In addition, the weight detection device 4100 is used to acquire several unit weight data of the cantilever element 3100 when different materials flow out of the liquid outlet 2000. The time measuring device 4200 is used to acquire several unit time data of different materials flowing out of the liquid outlet 2000, where each unit time data is the duration from the start to the end of the single material flow from the liquid outlet 2000. The data calculation device 4300 is used to acquire several unit weight data, several unit time data, and several unit density data, and calculate the fluid flow rate of the liquid outlet 2000 based on these data.

[0074] Therefore, when different materials are sequentially and individually discharged from the discharge device 2000, the weight detection device 4100 can acquire several unit weight data points borne by the cantilever element 3100 during the discharge of different materials. These unit weight data points represent the individual weights of the different materials being discharged. The time measurement device 4200 can acquire several unit time data points experienced during the discharge of different materials. Each unit time data point represents the duration from the start to the end of the discharge of a single material by the discharge device 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, once the fluid flow rate is obtained, the liquid output of dispenser 2000 can be calculated using the aforementioned formula, instead of relying on the weighing device 3000. This is because the weighing device 3000 obtains the liquid output after dispenser 2000 has already begun dispensing liquid; if the dispensing volume is excessive, the disposable beverage cup may overflow. However, by using the fluid flow rate to calculate the dispensing volume, the dispensing volume is actively calculated simultaneously with the dispensing process. When the dispensing volume reaches a preset range, a warning can be issued, and dispensing operation of dispenser 2000 can be automatically paused to prevent excessive dispensing and overflow of the disposable beverage cup.

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

[0078] This application provides a liquid dispensing machine, which includes a dispensing head. Since the technical solution, effects, and principles of the dispensing head have been described in detail above, they will not be repeated here. Any technical information regarding the dispensing head can be found in the foregoing description.

[0079] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0080] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
