Description

Technical Field

[0001] The present application relates to the field of food processing technology, and in particular to a liquid dispenser, a liquid dispensing head, and a liquid dispensing machine. Background Art

[0002] Milk tea-type prepared drinks are widely loved by consumers due to their good taste, and the demand for prepared drinks in the market is also increasing. The liquid dispensing machine is a machine used to make milk tea-type prepared drinks, which can make various types of milk tea-type drinks according to the order requirements of different types of drinks. Since the recipes of different types of drinks are different, a variety of different materials are needed to make prepared drinks. These materials are generally contained in different material barrels. Different material barrels are connected to different fluid outlet pipes centrally assembled on the liquid dispensing head through different fluid conveying pipes. When making drinks, predetermined types and predetermined amounts of materials can be sucked from different material barrels, and transported to different fluid outlet pipes of the liquid dispensing head through different fluid conveying pipes, and then centrally diverted to disposable beverage cups to complete the preparation of different types of drinks.

[0003] During the process of preparing mixed drinks by the liquid dispenser, the suction amount of some materials may be inaccurate. In particular, when there is a large deviation in the delivery amount of seasoning materials such as syrup, it will seriously affect the taste of the mixed drinks and affect the customer's eating experience. Summary of the Invention

[0004] Based on this, it is necessary to provide a liquid dispenser, a liquid discharge head and a liquid discharge machine to address the above-mentioned technical problems.

[0005] Regarding the aforementioned issue of inaccurate material suction, those skilled in the art have conducted extensive analysis and research, finding that material delivery blockage and obstruction are among the primary causes of inaccurate material suction. This blockage is primarily caused by the connection between the fluid delivery pipe and the various fluid outlet pipes on the discharge head.

[0006] Since several different types of materials need to be concentratedly transported to the liquid discharge head and flow out through different fluid outlet pipes on the liquid discharge head, in order to ensure that several materials flowing out of several fluid outlet pipes can be directly introduced into the milk tea cup at one time, the several fluid outlet pipes need to maintain a certain degree of concentration, at least the coverage area of ​​all fluid outlet pipes on the liquid discharge head cannot exceed the cup mouth area of ​​the milk tea cup.

[0007] The fluid outlet pipe can be designed with a smaller diameter and distributed as close together as possible on the outlet head. However, the fluid delivery pipe needs to be connected to other material barrels, so the diameter of the fluid delivery pipe is usually larger than the diameter of the fluid outlet pipe. Figure 2As shown in the figure, the larger diameter fluid delivery pipes connect to several material barrels at various locations throughout the entire delivery machine and then simultaneously lead to the delivery head. When bundled and tied together with the multiple fluid delivery pipes, some fluid delivery pipes will be twisted at large angles near the fluid delivery pipes. Different fluid delivery pipes extend from different locations to the delivery head, forming different twist angles. If the twist angle is too large, the space inside the fluid delivery pipe at the twisted position will be reduced, resulting in obstruction and blockage. For more viscous materials such as syrup, the obstruction and blockage will become more obvious due to the high viscosity and reduced internal space.

[0008] The amount of syrup affects the sweetness of a drink. Inaccurate amounts can cause variations in the sweetness of a drink, a factor that consumers value most, and therefore requires urgent attention. Furthermore, other flavoring ingredients, such as syrup, can affect the taste of a drink and ultimately influence the customer's experience.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0050] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0051] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0052] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, 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 embodiment.

[0053] After extensive analysis and research, those skilled in the art have discovered that inaccurate material suction volume can be caused by material blockage or obstruction during material delivery. This blockage is primarily caused by the connection between the fluid delivery tube 3100 and the fluid outlet tubes 2100 on the discharge head.

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

[0055] The fluid outlet pipe 2100 can be designed to have a smaller diameter and be distributed as close together as possible on the outlet head. However, the fluid delivery pipe 3100 needs to be connected to other material barrels, so the diameter of the fluid delivery pipe 3100 is usually larger than the diameter of the fluid outlet pipe 2100. Figure 2As shown, the larger diameter fluid outlet pipes 2100 connect to several material barrels at various locations throughout the entire liquid dispensing machine and then simultaneously guide to the liquid dispensing machine head. When assembled with the multiple fluid outlet pipes 2100 through a bundled arrangement, some fluid delivery pipes 3100 will experience large angle distortion near the fluid outlet pipes 2100. Different fluid delivery pipes 3100 extend from different locations toward the liquid dispensing machine head, resulting in different distortion angles. If the distortion angle is too large, the space inside the fluid delivery pipe 3100 will be reduced at the distorted location, causing blockage and obstruction. For more viscous materials such as syrups, the high viscosity and reduced internal space will make the blockage and obstruction more obvious.

[0056] The amount of syrup affects the sweetness of a drink. Inaccurate amounts can cause variations in the sweetness of a drink, a factor that consumers value most, and therefore requires urgent attention. Furthermore, other flavoring ingredients, such as syrup, can affect the taste of a drink and ultimately influence the customer's experience.

[0057] For the above technical issues, see Figures 1 to 4 As shown, the present application provides a liquid dispenser comprising a device assembly housing 1000 and a fluid outlet assembly 2000. Device assembly housing 1000 defines an internal cavity 1100, a chamber window for the internal cavity 1100 is defined at the top of device assembly housing 1000, and a plurality of fluid assembly holes 1200 are defined at the bottom of device assembly housing 1000. Device assembly housing 1000 can adopt various regular or irregular shapes, such as cylindrical, elliptical, or square, and is not limited here.

[0058] In one embodiment, the device assembly shell 1000 may include a shell side wall plate 1600 and a shell bottom wall plate 1700, the shell side wall plate 1600 is a cylindrical plate body, the interior of the shell side wall plate 1600 has an axially through inner cavity, the shell bottom wall plate 1700 is sealed and assembled at the end of the shell side wall plate 1600, the shell side wall plate 1600 and the shell bottom wall plate 1700 together enclose an inner cavity space 1100 of the device assembly shell 1000, and a number of fluid assembly holes 1200 are opened on the shell bottom wall plate 1700.

[0059] The fluid outlet assembly 2000 includes a plurality of fluid outlet tubes 2100, each of which is disposed within a fluid assembly hole 1200. Each fluid outlet tube 2100 comprises a connected middle tube body 2110, an inner tube body 2120, and an outer tube body 2130. The inner tube body 2120 and the outer tube body 2130 are located at opposite ends of the middle tube body 2110, respectively. The middle tube body 2110, the inner tube body 2120, and the outer tube body 2130 of the fluid outlet tube 2100 are different tube sections separated axially from the fluid outlet tube 2100. The middle tube body 2110, the inner tube body 2120, and the outer tube body 2130 of the fluid outlet tube 2100 form an integrally formed tube structure. In addition, the middle tube body 2110, the inner tube body 2120 and the outer tube body 2130 of the fluid outlet tube 2100 can also be separate tube bodies, which are connected to form a complete fluid outlet tube 2100. Those skilled in the art can design it according to actual needs and no limitation is made here.

[0060] like Figure 1 As shown, based on the distinction between the middle tube body 2110, the inner tube body 2120 and the outer tube body 2130 in the fluid outlet tube 2100, the middle tube body 2110 of each fluid outlet tube 2100 can be located in a matching fluid assembly hole 1200, the inner tube body 2120 of each fluid outlet tube 2100 can be located in the inner cavity space 1100, and the outer 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 tube body 2120 of each fluid outlet tube 2100 is the tube section portion used to connect to the fluid delivery tube 3100 in the inner cavity space 1100. Therefore, among the inner section tube bodies 2120 of several fluid outlet tubes 2100, at least a part or all of the inner section tube bodies 2120 of the fluid outlet tubes 2100 can be designed to be curved tube bodies. Based on the design of the curved tube bodies, the inner section tube bodies 2120 of several fluid outlet tubes 2100 can be distributed in a more dispersed state in the inner cavity space 1100 compared to the outer section tube bodies 2130.

[0062] The inner section tube body 2120 of the multiple fluid outlet pipes 2100 is based on a more dispersed distribution state. When the multiple fluid delivery pipes 3100 are connected to the multiple fluid outlet pipes 2100 in the inner cavity space 1100, the multiple fluid delivery pipes 3100 can also be presented in a more dispersed distribution state in the inner cavity space 1100. In this way, the looseness of the multiple fluid delivery pipes 3100 in the inner cavity space 1100 is improved. The more dispersed distribution state can avoid the adjacent fluid delivery pipes 3100 from squeezing each other in the inner cavity space 1100, and thus avoid deformation caused by mutual squeezing, thereby enabling the fluid delivery pipe 3100 to 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 pipe 3100.

[0063] Continue reading Figure 1 and Figure 2 As shown, in one embodiment, at least a portion or all of the outer tube section 2130 of the fluid outlet pipe 2100 can also be designed as a curved tube. In this case, the inner tube section 2120 of the fluid outlet pipe 2100 can be designed as a curved tube to disperse the inner tube sections 2120 more, while the outer tube section 2130 of the fluid outlet pipe 2100 can be designed as a curved tube to densely cluster the outer tube sections 2130, such as by curving toward the center. As a result, the density (or looseness) between the outer tube sections 2130 and the inner tube sections 2120 will be more different. When the outer tube sections 2130 of the fluid outlet tubes 2100 are densely packed with the mouth of the milk tea cup due to the design of the curved tube bodies, the inner tube sections 2120 of the fluid outlet tubes 2100 will be more dispersed relative to the outer tube sections 2130, thereby further increasing the looseness of the fluid delivery tubes 3100 in the inner cavity space 1100 and further avoiding mutual squeezing of adjacent fluid delivery tubes 3100 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 area 1300. The fluid outlet area 1300 is circular in shape, and all fluid assembly holes 1200 are distributed within the fluid outlet area 1300. The fluid outlet area 1300 has a central reference axis 1400. The end of the outer tube 2130 away from the middle tube 2110 serves as the outlet, and the central axis of the outlet is parallel to the central reference axis 1400.

[0065] Based on the above design of the device assembly housing 1000, at least a portion or all of the inner tube body 2120 of the fluid outlet tube 2100 is gradually bent in a direction away from the central reference axis 1400 from the middle tube body 2110 to the direction away from the middle tube body 2110, that is, Figure 1 As shown, the inner tube segments 2120 gradually bend from bottom to top in a direction away from the central reference axis 1400, dispersing toward the left and right sides, thereby widening the gaps between adjacent inner tube segments 2120 and presenting a more dispersed distribution. The maximum bending angle of the inner tube segments 2120 in the curved shape can be between 30 and 60 degrees.

[0066] At the same time, at least a portion or all of the outer tube 2130 of the fluid outlet tube 2100 gradually bends in the direction toward the central reference axis 1400 from the middle tube 2110 to the direction away from the middle tube 2110, that is, Figure 1 As shown, the outer tube segments 2130 gradually curve from top to bottom toward the central reference axis 1400, converging from the left and right sides toward the center. However, the radial distances between the central axes of adjacent outlets remain the same, demonstrating that, by comparison, the radial distances between at least some of the middle tube segments 2110 of the fluid outlet tubes 2100 have increased. Furthermore, by comparison, the radial distances between at least some of the inner tube segments 2120 of the fluid outlet tubes 2100 have also increased. The maximum bend angle of the curved outer tube segment 2130 can be between 30 and 60 degrees.

[0067] In one embodiment, the length of the outer tube section 2130 of the fluid outlet tubes 2100 is between 3 mm and 5 mm. This is because an outer tube section 2130 that is too long is difficult to clean, and an outer tube section 2130 that is too short can easily cause different materials to stick to each other when flowing out of the fluid outlet tube 2100. Due to liquid tension, the materials may remain at the outlet of the fluid outlet tube 2100, causing dripping. The outlet of the outer tube section 2130, which is away from the middle tube section 2110, is the outlet. The central axis of the outlet is parallel to the central reference axis 1400. Figure 3 As shown, the diameter of the fluid outlet area 1300 can be limited to between 63 mm and 66 mm, all the fluid assembly holes 1200 are evenly distributed in the fluid outlet area 1300, and the radial distances between the central axes of adjacent outlet pipes are equal.

[0068] Several fluid assembly holes 1200 can be distributed in a variety of 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 bending of the outer section tube body 2130 and the inner section tube body 2120 of several fluid outlet pipes 2100. Those skilled in the art can design according to actual needs and are not limited here.

[0069] At least two circular distribution trajectories 1500 with different diameters are defined in the fluid outlet area 1300, and the central axes of all the circular distribution trajectories 1500 coincide with the central reference axis 1400. A number of fluid assembly holes 1200 are distributed in a ring shape in the fluid outlet area 1300 along at least two circular distribution trajectories 1500, wherein the several fluid outlet pipes 2100 distributed on the innermost circular distribution trajectory 1500 are straight tube bodies, and the inner section tube body 2120 and the outer section tube body 2130 of the several fluid outlet pipes 2100 distributed on the remaining circular distribution trajectories 1500 are curved tube bodies.

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

[0071] See Figure 5 and Figure 6 As shown, the present application provides a liquid discharge head, which includes the liquid discharge device mentioned above, and also includes a fluid delivery assembly and a fluid drive assembly. The fluid delivery assembly includes several fluid delivery tubes 3100 mentioned above, and the number of fluid delivery tubes 3100 is configured to be the same as the number of fluid outlet tubes 2100, and each fluid delivery tube 3100 is connected to a fluid outlet tube 2100. The fluid drive assembly includes several gear pumps and several peristaltic pumps, each gear pump and each peristaltic pump is connected to a fluid delivery tube 3100, for driving the flow of fluid in different fluid delivery tubes 3100.

[0072] In the design of liquid dispensers, food safety is a top priority because their function is to prepare edible beverages. Typically, peristaltic pumps are used to drive the fluid through the pipeline. The advantage of peristaltic pumps is that they do not come into contact with the fluid while moving it through the pipeline, thus ensuring food safety. However, peristaltic pumps are not very precise when conveying materials.

[0073] Therefore, when designing the liquid delivery head for different materials, the present application employs different delivery methods based on their characteristics. For example, the fluid drive assembly incorporates both several gear pumps and several peristaltic pumps. The fluid delivery tube 3100, connected to the gear pumps, can be used to deliver syrup-like materials. Due to the high density of syrup, bacteria cannot grow inside the syrup. Therefore, even if the gear pump comes into contact with the syrup while driving the syrup, this does not affect the food safety and quality of the syrup. Furthermore, the gear pump's precise delivery volume allows it to precisely deliver the required amount of syrup, ensuring the desired flavor and texture of the prepared beverage. Other materials are prone to bacterial growth and present bacterial issues, so peristaltic pumps are used for delivery. While the delivery volume is not as precise as that of gear pumps, these materials (such as water and tea) do not significantly affect the taste of syrups. This demonstrates that the above design specifically selects different delivery methods based on the characteristics of different materials, representing a creative solution.

[0074] In one embodiment, the liquid dispensing head may include a head main shell 100, an operating screen 200 and a scanner 300. An assembly chamber is provided inside the head main shell 100, and an assembly window for the assembly chamber is provided at the bottom of the head main shell 100. The liquid dispenser is provided in the assembly window of the assembly chamber. The operating screen 200 is provided on the outer wall of the head main shell 100, and the operating screen 200 is connected to the fluid drive component.
