Description

Technical Field

[0001] This application relates to the field of food processing technology, and in particular to liquid dispensers, liquid dispenser heads, and liquid dispensers. Background Technology

[0002] Milk tea-type 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 a machine used to make milk tea-type flavored drinks, capable of preparing various types of milk tea drinks according to different orders. Since different types of drinks have different recipes, making flavored drinks requires various different ingredients. These ingredients are generally stored in different material containers, which are connected to different fluid dispensing pipes centrally mounted on the dispensing machine head via different fluid delivery pipes. During drink preparation, a predetermined type and amount of ingredients are drawn from different material containers, transported through different fluid delivery pipes to the different fluid dispensing pipes on the dispensing machine head, and then centrally guided into disposable drink cups, completing the preparation of different types of drinks.

[0003] During the preparation of beverages using a liquid dispensing machine, the suction volume of some materials may be inaccurate. In particular, if the delivery volume of flavoring materials such as syrups deviates significantly, it will seriously affect the taste of the beverage and the customer's dining experience. Summary of the Invention

[0004] Therefore, it is necessary to provide a liquid dispenser, a liquid dispenser head, and a liquid dispenser to address the aforementioned technical problems.

[0005] Regarding the aforementioned issue of inaccurate material suction volume, those skilled in the art, through extensive analysis and research, have discovered that obstruction and blockage during material transport are among the reasons for this inaccurate suction volume. Specifically, the primary location affecting obstructed material transport and blockage is the connection point between the fluid transport pipe and the different fluid outlet pipes on the liquid outlet head.

[0006] Since several different types of materials need to be transported to the liquid dispensing head and flow out through different fluid dispensing pipes on the liquid dispensing head, in order to ensure that the materials flowing out of the several fluid dispensing pipes can be directly introduced into the milk tea cup at one time, the several fluid dispensing pipes need to be concentrated to a certain extent. At least the area covered by all the fluid dispensing pipes on the liquid dispensing head cannot exceed the area of ​​the mouth of the milk tea cup.

[0007] The fluid outlet pipe can be designed with a smaller diameter and should be arranged in a clustered pattern at the outlet head. However, since the fluid delivery pipe needs to be connected to other material containers, its diameter is usually larger than that of the fluid outlet pipe. (See reference...) Figure 2As shown, a larger diameter fluid outlet pipe connects to several material containers at various locations throughout the dispensing machine, and then simultaneously guides them to the dispensing head. During the assembly of the bundled and tied fluid outlet pipes, some fluid delivery pipes will experience large-angle twists near the fluid outlet pipes. Different fluid delivery pipes extending towards the dispensing head from different locations will also form different twist angles. If the twist angle is too large, it will reduce the internal space of the fluid delivery pipe at the twist location, resulting in blockages and sluggishness. For viscous materials such as syrups, the high viscosity and reduced internal space will exacerbate the blockages and sluggishness.

[0008] The amount of syrup-like ingredients affects the sweetness of prepared drinks. Inaccurate dosage can alter the sweetness, which is a crucial factor for customers and therefore urgently needs to be addressed. In addition, other flavoring ingredients such as syrups also influence the taste of prepared drinks, ultimately determining the customer's dining experience.

[0009] To address the aforementioned technical problems, this application provides a liquid dispensing device, the liquid dispensing device comprising:

[0010] The device assembly housing has an internal cavity space inside, a chamber window of the internal cavity space is opened at the top of the device assembly housing, and several fluid assembly holes are opened at the bottom of the device assembly housing.

[0011] A fluid outlet assembly includes a plurality of fluid outlet pipes, each of which is inserted into a fluid assembly hole. Each fluid outlet pipe comprises a connected middle section, an inner section, and an outer section. The inner and outer sections are located at opposite ends of the middle section. The middle section of each fluid outlet pipe is located within a matching fluid assembly hole. The inner section is located within an inner cavity, and the outer section is located outside the inner cavity. At least a portion of the inner sections of the fluid outlet pipes are curved.

[0013] In one embodiment, the bottom of the device assembly housing defines a fluid outlet region, the fluid outlet region being circular in shape, all of the fluid assembly holes being distributed within the fluid outlet region, and the fluid outlet region having a central reference axis; wherein:

[0014] At least a portion of the inner section of the fluid outlet pipe gradually bends away from the central reference axis from its middle section toward the direction away from the middle section; and / or, at least a portion of the outer section of the fluid outlet pipe gradually bends toward the central reference axis from its middle section toward the direction away from the middle section.

[0015] In one embodiment, the length of the outer section of the plurality of fluid outlet pipes is between 3 mm and 5 mm; and / or,

[0016] The outer section of the pipe, away from the middle section, is the liquid outlet. The central axis of the liquid outlet is parallel to the central reference axis. The diameter of the fluid outlet area is between 63mm and 66mm. All the fluid assembly holes are evenly distributed within the fluid outlet area. The radial distance between the central axes of adjacent liquid outlets is equal.

[0017] In one embodiment, at least two annular distribution tracks with different diameters are defined within the fluid outlet region. The central axis of all the annular distribution tracks coincides with the central reference axis. A plurality of fluid assembly holes are distributed in a ring along the at least two annular distribution tracks within the fluid outlet region. The plurality of fluid outlet pipes distributed on the innermost annular distribution track are straight pipes, while the inner and outer sections of the plurality of fluid outlet pipes distributed on the remaining annular distribution tracks are curved pipes.

[0018] In one embodiment, the fluid outlet region is defined by a first annular distribution trajectory and a second annular distribution trajectory, the diameter of the first annular distribution trajectory being smaller than that of the second annular distribution trajectory. The bottom of the device assembly housing has twelve fluid assembly holes. The fluid outlet assembly includes twelve fluid outlet pipes, four of which are located on the first annular distribution trajectory, and the remaining eight are located on the second annular distribution trajectory; and / or,

[0019] The device assembly housing includes a housing side wall plate and a housing bottom wall plate. The housing side wall plate is a cylindrical plate with an axially penetrating inner cavity. The housing bottom wall plate is sealed and assembled at 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 of the device assembly housing. A plurality of fluid assembly holes are formed on the housing bottom wall plate.

[0020] This application provides a liquid dispensing head, the liquid dispensing head comprising:

[0021] The liquid outlet;

[0022] A fluid delivery assembly, the fluid delivery assembly comprising a plurality of fluid delivery pipes, the number of the fluid delivery pipes being configured to be the same as the number of the fluid outlet pipes, each of the fluid delivery pipes being connected to one of the fluid outlet pipes;

[0023] A fluid drive assembly comprising a plurality of gear pumps and a plurality of peristaltic pumps, each gear pump and each peristaltic pump being connected to a fluid delivery pipe for driving fluid flow within the respective fluid delivery pipes.

[0024] In one embodiment, the dispensing head includes:

[0025] The main housing of the machine head has an assembly chamber inside, and an assembly window for the assembly chamber is opened at the bottom of the main housing of the machine head.

[0026] The liquid outlet is located at the assembly window of the assembly chamber;

[0027] An operation screen is disposed on the outer wall of the main housing of the machine head, and the operation screen is connected to the fluid drive assembly;

[0028] A scanner is disposed on the outer wall of the main housing of the head unit and is connected to the operation screen.

[0030] A cleaner, comprising a cleaning base, a cleaning assembly, and a locking assembly, wherein the cleaning base has a cleaning cavity with a cavity window, and the cleaning cavity of the cleaning base is used to accommodate at least a plurality of the outer sections of the fluid outlet pipes through the cavity window;

[0031] The cleaning assembly is disposed inside the cleaning cavity, and the cleaning assembly is used to clean at least the outer sections of the fluid outlet pipes;

[0032] The locking assembly is disposed on the cleaning base, and the cleaning base is fixedly connected to the liquid outlet through the locking assembly.

[0033] This application provides a liquid dispensing machine, which includes the liquid dispensing head.

[0034] In the aforementioned liquid dispenser, liquid dispenser head, and liquid dispenser, at least some or all of the inner sections of the fluid dispensing pipes are designed as curved pipes. Based on this curved pipe design, the inner sections of several fluid dispensing pipes can be more dispersed within the inner cavity compared to their outer sections. When several fluid conveying pipes are connected to several fluid dispensing pipes within the inner cavity, the fluid conveying pipes can also be more dispersed within the inner cavity. This increases the looseness of the fluid conveying pipes within the inner cavity, and the more dispersed distribution prevents adjacent fluid conveying pipes from squeezing each other within the inner cavity, thus avoiding deformation caused by mutual squeezing. This allows the fluid conveying pipes to transport materials within their normal internal space, preventing material from becoming obstructed or blocked at deformed locations within the fluid conveying pipes.

[0047] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0048] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0049] 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] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0051] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0052] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0053] Regarding the issue of inaccurate material suction volume, those skilled in the art, through extensive analysis and research, have discovered that obstruction and blockage during material transport are among the reasons for inaccurate suction volume. Specifically, the main location affecting obstructed material transport and blockage is the connection point between the fluid transport pipe 3100 and the different fluid outlet pipes 2100 on the liquid outlet head.

[0054] Since several different types of materials need to be centrally transported to the liquid dispensing head and flow outward through different fluid dispensing pipes 2100 on the liquid dispensing head, in order to ensure that the materials flowing out of the several fluid dispensing pipes 2100 can be directly introduced into the milk tea cup at one time, the several fluid dispensing pipes 2100 need to maintain a certain degree of concentration and convergence. At least the area covered by all the fluid dispensing pipes 2100 on the liquid dispensing head cannot exceed the area of ​​the mouth of the milk tea cup.

[0055] The fluid outlet pipe 2100 can be designed with a smaller diameter and should be arranged in a clustered manner on the outlet head. However, the fluid delivery pipe 3100 needs to be connected to other material containers, so the diameter of the fluid delivery pipe 3100 is usually larger than the diameter of the fluid outlet pipe 2100. (See reference...) Figure 2As shown, a larger diameter fluid outlet pipe 2100 connects to several material containers at various locations throughout the dispensing machine, and then simultaneously guides them to the dispensing head. When the fluid delivery pipes 3100 are bundled and assembled with the dispensing pipes 2100, some fluid delivery pipes 3100 will be twisted at a large angle near the fluid outlet pipe 2100. Different fluid delivery pipes 3100 extend towards the dispensing head from different positions, and will also form different twist angles. Once the twist angle is too large, it will reduce the internal space of the fluid delivery pipe 3100 at the twist position, thus causing obstruction and blockage. For viscous materials such as syrups, the obstruction and blockage will be more obvious due to the high viscosity and reduced internal space.

[0056] The amount of syrup-like ingredients affects the sweetness of prepared drinks. Inaccurate dosage can alter the sweetness, which is a crucial factor for customers and therefore urgently needs to be addressed. In addition, other flavoring ingredients such as syrups also influence the taste of prepared drinks, ultimately determining the customer's dining experience.

[0057] For the above technical issues, please refer to Figures 1 to 4 As shown, this application provides a liquid dispenser, which includes a device assembly housing 1000 and a fluid dispensing assembly 2000. The device assembly housing 1000 has an internal cavity space 1100, a chamber window for the internal cavity space 1100 is formed at the top of the device assembly housing 1000, and a plurality of fluid assembly holes 1200 are formed at the bottom of the device assembly housing 1000. The device assembly housing 1000 can adopt various regular or irregular shapes such as cylindrical, elliptical, and square, and is not limited thereto.

[0058] In one embodiment, the device assembly housing 1000 may include a housing side wall plate 1600 and a housing bottom wall plate 1700. The housing side wall plate 1600 is a cylindrical plate with an axially through cavity inside. The housing bottom wall plate 1700 is sealed and assembled at the end of the housing side wall plate 1600. The housing side wall plate 1600 and the housing bottom wall plate 1700 together enclose the inner cavity space 1100 of the device assembly housing 1000. A plurality of fluid assembly holes 1200 are formed in the housing bottom wall plate 1700.

[0059] The fluid outlet assembly 2000 includes several fluid outlet pipes 2100, each of which is inserted into a fluid assembly hole 1200. Each fluid outlet pipe 2100 includes a connected middle section pipe body 2110, an inner section pipe body 2120, and an outer section pipe body 2130. The inner section pipe body 2120 and the outer section pipe body 2130 are located at opposite ends of the middle section pipe body 2110. The middle section pipe body 2110, the inner section pipe body 2120, and the outer section pipe body 2130 of the fluid outlet pipe 2100 are different pipe segments separated along the axial direction of the fluid outlet pipe 2100. The middle section pipe body 2110, the inner section pipe body 2120, and the outer section pipe body 2130 of the fluid outlet pipe 2100 are integrally formed pipe structures. In addition, the middle section 2110, inner section 2120 and outer section 2130 of the fluid outlet pipe 2100 can also be separate pipes, which can be connected to form a complete fluid outlet pipe 2100. Those skilled in the art can design according to actual needs, and no limitation is made here.

[0060] like Figure 1 As shown, based on the distinction between the middle section tube body 2110, the inner section tube body 2120, and the outer section tube body 2130 in the fluid outlet tube 2100, the middle section tube body 2110 of each fluid outlet tube 2100 can be located within a matching fluid assembly hole 1200, the inner section tube body 2120 of each fluid outlet tube 2100 can be located within the inner cavity space 1100, and the outer section tube body 2130 of each fluid outlet tube 2100 can be located outside the inner cavity space 1100.

[0061] like Figure 2 As shown, in this assembly structure, the inner section 2120 of each fluid outlet pipe 2100 is a pipe section in the inner cavity space 1100 used to connect with the fluid delivery pipe 3100. Therefore, in the inner section 2120 of several fluid outlet pipes 2100, at least some or all of the inner section 2120 of the fluid outlet pipes 2100 can be designed as curved pipes. Based on the design of the curved pipes, the inner section 2120 of several fluid outlet pipes 2100 can be distributed more dispersedly in the inner cavity space 1100 than the outer section 2130.

[0062] The inner sections 2120 of the fluid outlet pipes 2100 are arranged in a more dispersed manner. When the fluid delivery pipes 3100 are connected to the fluid outlet pipes 2100 in the inner cavity space 1100, the fluid delivery pipes 3100 can also be arranged in a more dispersed manner in the inner cavity space 1100. This improves the looseness of the fluid delivery pipes 3100 in the inner cavity space 1100. The more dispersed distribution can prevent adjacent fluid delivery pipes 3100 from squeezing each other in the inner cavity space 1100, thereby avoiding deformation caused by mutual squeezing. As a result, the fluid delivery pipes 3100 can transport materials in a normal internal space, avoiding the situation where the material is not smooth or blocked at the deformed position of the fluid delivery pipes 3100.

[0063] Continue reading Figure 1 and Figure 2 As shown, in one embodiment, at least some or all of the outer section 2130 of the fluid outlet pipe 2100 can also be designed as a curved pipe. In this case, the inner section 2120 of the fluid outlet pipe 2100 can be designed as a curved pipe that makes the several inner sections 2120 more dispersed, while the outer section 2130 of the fluid outlet pipe 2100 can be designed as a curved pipe that makes the several outer sections 2130 more dense, such as converging and bending towards the center. Therefore, the density (or looseness) between the several outer sections 2130 and the several inner sections 2120 will differ more significantly. When the outer sections 2130 of the fluid outlet pipes 2100 are densely packed to match the mouth of the milk tea cup through the design of the curved pipe body, the inner sections 2120 of the fluid outlet pipes 2100 will be more dispersed in distribution relative to the outer sections 2130. This further increases the looseness of the fluid delivery pipes 3100 in the inner cavity space 1100 and further avoids the adjacent fluid delivery pipes 3100 from squeezing each other in the inner cavity space 1100.

[0064] See Figure 3 As shown, in one embodiment, the bottom of the device assembly housing 1000 defines a fluid outlet region 1300, which is circular in shape. All fluid assembly holes 1200 are distributed within the fluid outlet region 1300, which has a central reference axis 1400. The outer tube 2130, at the end furthest from the middle tube 2110, serves as the fluid outlet, and its central axis is parallel to the central reference axis 1400.

[0065] Based on the above design of the device assembly housing 1000, at least part or all of the inner section 2120 of the fluid outlet pipe 2100 gradually bends away from the central reference axis 1400 from the middle section 2110 towards the direction away from the middle section 2110. Figure 1 As shown, the inner tube 2120 gradually bends from bottom to top along a direction away from the central reference axis 1400, dispersing to the left and right sides, thus widening the gap between adjacent inner tubes 2120 and presenting a more dispersed distribution. The maximum bending angle of the curved inner tube 2120 can be between 30 degrees and 60 degrees.

[0066] Simultaneously, at least part or all of the outer section 2130 of the fluid outlet pipe 2100 gradually bends in the direction toward the central reference axis 1400 from the middle section 2110 away from the middle section 2110, i.e. Figure 1 As shown, the outer section 2130 gradually bends from top to bottom along the direction towards the central reference axis 1400, converging from both sides towards the center. However, the radial distance between the central axes of adjacent outlet pipes remains equal, which proves that, in comparison, the radial distance between at least some of the middle sections 2110 of the fluid outlet pipe 2100 has increased, and further, the radial distance between at least some of the inner sections 2120 of the fluid outlet pipe 2100 has also further increased. The maximum bending angle of the curved outer section 2130 can be between 30 degrees and 60 degrees.

[0067] In one embodiment, the length of the outer section 2130 of the plurality of fluid outlet pipes 2100 is between 3 mm and 5 mm. This is because if the outer section 2130 is too long, it is difficult to clean; if it is too short, different materials may stick together as they flow out of the fluid outlet pipe 2100, leaving residue at the outlet of the fluid outlet pipe 2100 due to liquid surface tension, causing dripping. The end of the outer section 2130 furthest from the middle section 2110 is the outlet, and the central axis of the outlet is parallel to the central reference axis 1400. (See reference...) Figure 3 As shown, the diameter of the fluid outlet area 1300 can be limited to between 63 mm and 66 mm. All fluid assembly holes 1200 are evenly distributed within the fluid outlet area 1300, and the radial distance between the central axes of adjacent outlet ports is equal.

[0068] The fluid assembly holes 1200 can be distributed in various ways, such as circular ring distribution, square ring distribution, elliptical ring distribution, and other regular or irregular ways. Different distribution methods will determine the distribution form of different fluid outlet pipes 2100, as well as the degree of curvature of the outer section pipe body 2130 and the inner section pipe body 2120 in the fluid outlet pipes 2100. Those skilled in the art can design according to actual needs, and no limitation is made here.

[0069] The fluid outlet area 1300 is defined by at least two annular distribution tracks 1500 with different diameters. The central axis of all annular distribution tracks 1500 coincides with the central reference axis 1400. A number of fluid assembly holes 1200 are distributed in a ring along the at least two annular distribution tracks 1500 in the fluid outlet area 1300. Among them, the fluid outlet pipes 2100 distributed on the innermost annular distribution track 1500 are straight pipes, while the inner section 2120 and outer section 2130 of the fluid outlet pipes 2100 distributed on the remaining annular distribution tracks 1500 are curved pipes.

[0070] See Figure 4 As shown, in one embodiment, a first annular distribution trajectory 1500 and a second annular distribution trajectory 1500 are defined within the fluid outlet region 1300. The diameter of the first annular distribution trajectory 1500 is smaller than that of the second annular distribution trajectory 1500. The fluid outlet region 1300 is located within... Figure 4 The inner circle is the first circular distribution trajectory 1500, located in... Figure 4 The outer ring is the second circular distribution trajectory 1500. The bottom of the device assembly housing 1000 has twelve fluid assembly holes 1200. The fluid outlet assembly 2000 includes twelve fluid outlet pipes 2100, of which four fluid assembly holes 1200 are located on the first circular distribution trajectory 1500, and the remaining eight fluid assembly holes 1200 are located on the second circular distribution trajectory 1500.

[0071] See Figure 5 and Figure 6 As shown, this application provides a liquid dispensing head, which includes the aforementioned liquid dispenser, as well as a fluid delivery assembly and a fluid drive assembly. The fluid delivery assembly includes a plurality of the aforementioned fluid delivery pipes 3100, the number of which is configured to be the same as the number of fluid outlet pipes 2100, with each fluid delivery pipe 3100 connected to one fluid outlet pipe 2100. The fluid drive assembly includes a plurality of gear pumps and a plurality of peristaltic pumps, each gear pump and each peristaltic pump being connected to one fluid delivery pipe 3100 for driving fluid flow within the different fluid delivery pipes 3100.

[0072] In the design of liquid dispensing machines, since their function is to prepare edible beverages, food safety is of paramount importance. In typical designs, peristaltic pumps are chosen to drive the fluid flow through the pipes. The advantage of peristaltic pumps is that they do not come into contact with the fluid while driving its flow, thus ensuring food safety. However, peristaltic pumps are not very precise in conveying materials.

[0073] Therefore, the dispensing head of this application employs different conveying methods tailored to the characteristics of different materials. For example, several gear pumps and several peristaltic pumps are used simultaneously in the fluid drive assembly. The fluid delivery pipe 3100 connected to the gear pump can be used to convey syrup-like materials. Due to the high density of syrup, bacteria do not grow inside it. Therefore, even if the gear pump comes into contact with the syrup during its flow, it will not affect the food safety and quality of the syrup. The gear pump's precise pumping volume can accurately deliver the required amount of syrup, ensuring that the flavor of the prepared beverage meets expectations and guarantees the taste. Other materials are prone to bacterial growth and have bacterial issues. Therefore, peristaltic pumps are used for conveying. Although the delivery volume is not as precise as that of gear pumps, other materials (such as water, tea, etc.) will not significantly affect the taste like syrup. Thus, the above design specifically selects different conveying methods for the characteristics of different materials, representing a creative design solution.

[0074] In one embodiment, the dispensing head may include a main housing 100, an operation screen 200, and a scanner 300. The main housing 100 has an internal assembly chamber, and an assembly window for the assembly chamber is located at the bottom of the main housing 100. The dispensing device is disposed within the assembly window of the assembly chamber. The operation screen 200 is disposed on the outer wall of the main housing 100 and is connected to the fluid drive assembly. The scanner 300 is disposed on the outer wall of the main housing 100 and is connected to the operation screen 200. The dispensing machine can be operated by an operator through the operation screen 200. The scanner 300 can scan order identification codes (barcodes, QR codes, etc.) for automatic dispensing.

[0075] In one embodiment, the dispensing head may further include a cleaner, which is an accessory specifically designed for cleaning several fluid dispensing pipes 2100 on the dispensing head. The cleaner may include a cleaning base, a cleaning assembly, and a locking assembly. The cleaning base has a cleaning cavity with a cavity window, which is used to accommodate at least several outer sections 2130 of the fluid dispensing pipes 2100 through the cavity window. The cleaning assembly is disposed inside the cleaning cavity and is used to clean at least several outer sections 2130 of the fluid dispensing pipes 2100. The locking assembly is disposed on the cleaning base, and the cleaning base is fixedly connected to the dispensing head via the locking assembly.

[0076] like Figure 5 and Figure 6As shown, during cleaning, the operator can oriented the cavity window of the cleaner towards the desired direction, inject cleaning fluid into the cleaning cavity, and then invert the cleaner onto the bottom of the outlet. At this time, the outer sections 2130 of several fluid outlet pipes 2100 in the outlet can be accommodated within the cleaning cavity, and a portion of the component assembly housing 1000 of the outlet will also be accommodated within the cleaning cavity. The outer sections 2130 of the several fluid outlet pipes 2100 can then be immersed in the cleaning fluid within the cleaning cavity. The locking assembly is responsible for fixing the cleaner and the outlet relative to each other, maintaining the outer sections of the several fluid outlet pipes 2100 in the outlet immersed in the cleaning fluid within the cleaning cavity of the cleaner. The locking assembly can employ various fixing methods such as magnetic attraction, snap-fit, and threaded connection; no specific method is limited here.

[0077] In addition, the cleaner can also be designed with a cleaning component. When the outer sections of several fluid outlet pipes 2100 are immersed in the cleaning solution in the cleaning cavity of the cleaner, the cleaning component can perform an active cleaning operation while immersing. For example, the cleaning component may include a rotating brush driven by a motor or manually. During the rotation, the rotating brush will contact the outer sections of several fluid outlet pipes 2100 to brush the outer sections of several fluid outlet pipes 2100 and improve the cleaning effect.
