[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example 1:

[0020] This embodiment provides a stirring device suitable for a coffee and milk tea machine preparation system, specifically as follows: Figures 1-3 As shown, it includes: a stirring section for mixing raw materials; a stirring tank for holding raw materials; and a valve group for opening and closing the stirring tank. The stirring section includes a drive motor 101, a stirring blade 106, and a rotating rod 109. The stirring blade 106 is mounted on the rotating rod 109, and the rotating rod 109 is rotatably connected to the stirring tank. The drive motor 101 is driven by the rotating rod 109. The stirring tank is provided with a discharge port and multiple connecting nozzles 104. The connecting nozzles 104 are used to introduce raw materials, and different connecting nozzles 104 are connected to different raw material pipes, such as milk, tea, coffee, syrup, water, gas, etc. The valve group includes a control unit and a plug 107. The plug 107 is used to block the discharge port. The control unit, connecting nozzles 104, and drive motor 101 are centrally located.

[0021] By centrally arranging the control unit, connecting nozzle 104, and drive motor 101, no valve control device is installed at the discharge port below the mixing tank, which facilitates the receiving of coffee and milk tea from below. The upper part of the mixing tank is also covered and hidden, making the appearance more aesthetically pleasing. Furthermore, during maintenance, most faults can be diagnosed and repaired from a single maintenance position, facilitating subsequent maintenance work.

[0022] Example 2:

[0023] This embodiment further extends the above embodiment, specifically as follows: Figure 2 As shown, the control unit includes a power component and a slide rod 108. The slide rod 108 is mounted on the rotating rod 109, and the plug 107 is mounted on one end of the slide rod 108. The other end of the slide rod 108 is connected to the power component for transmission. The power component is used to drive the slide rod 108 to reciprocate longitudinally, thereby driving the plug 107 to open and close the mixing tank.

[0024] Furthermore, the power component includes a linkage rod 102, a cylinder 103, and a tension spring 111. The cylinder 103 is mounted on the mixing tank, the linkage rod 102 is connected to the output end of the cylinder 103, and one end of the tension spring 111 is connected to the linkage rod 102, while the other end is connected to the mixing tank. When the beverage is prepared, the cylinder 103 extends, at which point the linkage rod 102 drives the slide rod 108 to rise, the tension spring 111 is stretched, and the plug 107 no longer blocks the discharge port, allowing the beverage to flow out and be packaged. After completion, the cylinder 103 resets and the power is cut off. Under the action of the tension spring 111, the linkage rod 102 presses down on the slide rod 108, that is, the plug 107 presses against the discharge port, achieving a sealing effect.

[0025] Furthermore, the drive motor 101 is connected to the rotating rod 109 via a belt. The belt connection allows the position of the drive motor 101 to be flexibly adjusted according to the design and spatial layout.

[0026] Furthermore, the mixing tank includes a tank body 105 and a tank cover 110. The discharge port is located on the tank body 105, and the mixing unit and valve assembly are installed on the tank cover 110. The split design allows for subsequent maintenance by simply removing the tank cover 110 without moving the tank body 105.

[0027] Furthermore, a sealing ring is provided on the bucket lid 110, and the bucket lid 110 is detachably connected to the bucket body 105 by bolts. Disassembly and installation are convenient, and the seal prevents foreign objects from entering.

[0028] Specific working principle: Depending on the beverage to be prepared, the raw materials are selectively introduced into the mixing tank through different connecting nozzles 104 via external pipelines. At the same time, the drive motor 101 is started, and the stirring blades 106 begin to stir the raw materials. After stirring, the cylinder 103 extends, and the plug 107 moves upward, allowing the beverage to flow into the cup below in one go. After the material is dispensed, the cylinder 103 picks up the gas source, and under the action of the tension spring 111, the plug 107 closes the mixing tank again. If the next customer orders the same product, there is no need to clean the mixing tank; the mixing can be done directly. If a different product is ordered, clean water is sprayed into the mixing tank through the corresponding connecting nozzle 104 for cleaning. After cleaning, the plug 107 is raised, and the wastewater is discharged and collected by the funnel (which is not part of this device and will not be described in detail here). Then, the air valve is opened, and the air is blown into the mixing tank through the corresponding connecting nozzle 104 to blow out the water adhering to its inner wall, preventing it from affecting the taste of the next cup of beverage.

[0029] This device utilizes multi-raw material parallel injection and stirring technology to achieve uniform blending of coffee and syrup within 50 seconds, resulting in a smoother taste than manual shaking. The stirring tank can be pre-cleaned or reused, reducing ineffective rinsing by 80% and saving 76% of water. It increases continuous production efficiency by 3 times, with a peak single-machine capacity of 40 cups / hour. The integrated and self-cleaning design minimizes water consumption during cleaning. It is compatible with fully automatic coffee vending machines, fully automatic milk tea vending machines, coffee and milk tea vending carts, and mobile retail carts, supporting various coffee, milk tea (non-large solid ingredients), and beverage recipes. Maintenance costs are reduced by 60%, while supporting flexible production of over 50 beverages, achieving a closed-loop business value system integrating "rapid production + premium taste + full-scenario penetration."

[0030] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
