Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] As described in the background, in existing production, different media need to be mixed to achieve uniform stirring, for example, it is necessary to mix multiple liquids or mix between liquid and gas, etc. In order to achieve a better mixing effect, the current solution is more about pre-delivering multiple liquids or liquids and gases to a container, and then achieving stirring and mixing through a power stirring device provided in the container. In this production method, the solution of first delivering and converging multiple mixed liquids and gases and then mixing and stirring them affects the efficiency of mixing and stirring. In order to better solve this problem, the researchers in this application propose a mixer. The mixer in this application can achieve mixing when delivering multiple liquids or liquids and gases, etc., so as to improve the mixing rate of multiple media.

[0028] It should be noted that the mixer in the present application can be applied to various fields, such as beverage equipment but not limited thereto.

[0029] like Figure 1 As shown, Figure 1The figure is a schematic diagram of the structure of a mixer in one embodiment of the present application. In this embodiment, the mixer includes: a main shaft 100 and a mixing unit 200. The outer wall of the main shaft 100 is provided with a flow channel 110, and the mixing unit 200 is disposed in the flow channel 110. When multiple liquids or liquids and gases flow through the flow channel 110, they can collide with the mixing unit 200 to generate turbulent vortices, thereby achieving mixing of multiple media. In other words, multiple media can be mixed during the process of conveying multiple media, thereby improving mixing efficiency.

[0030] Specifically, a flow channel 110 is provided on the outer wall of the main shaft 100, wherein the extension trajectory of the flow channel 110 can be a linear trajectory or a nonlinear trajectory, the inlet of the flow channel 110 is connected to the edge of one end of the main shaft 100, and the outlet of the flow channel 110 is connected to the edge of the other end of the main shaft 100; the mixing unit 200 is provided on the side wall of the flow channel 110, and the mixing unit 200 can collide and contact with the gas and liquid flowing through the flow channel 110, wherein the number of the mixing units 200 can be multiple.

[0031] In this embodiment, the mixer is directly arranged in the pipeline, and the flow channel 110 of the main shaft body faces the inner wall of the pipeline. Figure 1 , entering flow channel 110 from the position indicated by arrow a and then exiting flow channel 110 from the position indicated by arrow b. During this process, the gas and liquid collide and contact with mixing unit 200, forming turbulent vortices, thereby promoting the thorough mixing of liquids and liquids, and liquids and gases. This turbulent effect not only achieves effective stirring and mixing of multiple liquids or gases, but also significantly increases the mixing rate.

[0032] Furthermore, the mixer in this embodiment utilizes a flow channel 110 on the outer wall of the main shaft 100, rather than an internal flow channel design. This is because, first, when flow channel 110 is located within the main shaft, the flow channel cross-section is larger, reducing the fluid flow rate and resulting in a weakened turbulence intensity, thus limiting the mixing effect. Furthermore, the complex geometry of the internal flow channel can easily cause fluid turbulence and localized flow lag, thereby increasing energy loss.

[0033] In contrast, positioning flow channel 110 on the outer wall of main shaft 100 allows for a narrower flow channel 110, resulting in a higher fluid velocity. This makes it easier to generate and maintain turbulence, significantly enhancing the mixing effect of the media. Flow in narrow flow channel 110 generates more concentrated turbulence, effectively reducing ineffective mixing areas. Furthermore, the design of flow channel 110 on the outer wall avoids the localized eddies and hysteresis regions common in larger cross-section flow channels, thereby reducing unnecessary energy loss.

[0034] Finally, the design of the flow channel 110 on the outer wall also simplifies the manufacturing and cleaning process of the mixer, further improving the usability and maintenance efficiency of the equipment.

[0035] In one embodiment, see Figure 2 As shown, the mixing unit 200 includes a first spoiler 210 . At least one side wall of the flow channel 110 is provided with the first spoiler 210 . The first spoiler 210 protrudes from the side wall of the flow channel 110 .

[0036] In the present embodiment, since the first spoiler 210 protrudes from the side wall of the flow channel 110, when the multiple media flow in the flow channel 110 of the main shaft body, the multiple media can collide and contact with the first spoiler 210 in the mixing unit 200. Under the action of the first spoiler 210, the flow trajectory of the original multiple media is disturbed, thereby causing the flow direction of the multiple media to be deflected and forming a small-scale vortex structure in the downstream area of the first spoiler 210. These small-scale vortex structures enhance the mixing intensity of the multiple media by strengthening local turbulence, so that the different components in the fluid are quickly involved in the high-intensity turbulent area, thereby promoting full mixing between the media. It can be understood that the different components in the fluid can be quickly introduced into the high-intensity turbulent area formed by these small-scale vortices, thereby promoting full mixing between the different media. In addition, the small-scale vortex not only accelerates the contact process between the media, but also can improve the momentum exchange efficiency between the different components, thereby achieving a more efficient mixing effect in a shorter time.

[0037] In one embodiment, the mixing unit 200 further includes a second spoiler 220, the first spoiler 210 is arranged on one side of the flow channel 110, and the second spoiler 220 is arranged on the other side of the flow channel 110, the first spoiler 210 and the second spoiler 220 are arranged in an interlaced manner relative to each other, and a buffer space 230 is formed between the first spoiler 210 and the second spoiler 220.

[0038] In the present embodiment, a first spoiler 210 and a second spoiler 220 are provided in the mixing unit 200, which are respectively located on both sides of the flow channel 110 and are relatively staggered. Through this staggered arrangement, after the fluid flows through the first spoiler 210, its flow trajectory is disturbed and deflected, and when the fluid approaches the second spoiler 220, collision and disturbance occur again. Due to the formation of a buffer space 230 between the first spoiler 210 and the second spoiler 220, the fluid obtains a certain buffer and redistribution in this area, which helps to avoid excessive turbulence in the fluid after continuous disturbance, thereby better controlling turbulence intensity and ensuring the stability and uniformity of the mixing process. In addition, the design scheme in the present embodiment can also effectively reduce the stagnant flow area and dead zone in the flow channel 110, ensuring that the fluid in each area of the mixer can fully flow and mix. Especially when processing high viscosity media or multiphase fluids, the staggered first spoiler 210 and the second spoiler 220 can more effectively break the laminar flow state of the medium, improve its uniformity and mixing efficiency. Therefore, in this embodiment, the fluid mixing effect is improved by staggered arrangement of the first spoilers 210 and the second spoilers 220 , while ensuring the stability of the mixing process and the energy utilization efficiency.

[0039] Furthermore, in one embodiment, the spacing of the buffer spaces 230 is 3 to 5 times the height of the first spoiler 210 or the first spoiler 210 .

[0040] In this embodiment, the spacing of the buffer spaces 230 is set to 3 to 5 times the height of the first spoiler 210 or the second spoiler 220. The main purpose of this design is to provide an appropriate buffer area for the fluid to balance the degree of turbulence after it flows through the first spoiler 210 and the second spoiler 220. After the fluid passes through the first spoiler 210, the first spoiler 210 acts to deflect the fluid flow direction and generate turbulence. Without a suitable buffer space 230, continuous turbulence may cause excessive turbulence in the fluid, thereby increasing energy loss and reducing mixing efficiency. Providing a buffer space 230 that is 3 to 5 times the height of the first spoiler 210 helps maintain the turbulence intensity within an appropriate range, allowing the fluid to recover from the turbulence after passing through the first spoiler 210 and redistributing the flow velocity and direction. This ensures that the turbulence intensity is moderate when the fluid reaches the second spoiler 220, which is conducive to subsequent mixing. At the same time, the provision of the buffer space 230 slows down the changes in turbulence intensity, prevents excessive fluctuations in turbulence intensity, and reduces uneven flow within the flow channel 110.

[0041] In one embodiment, the first spoiler 210 is polygonal, for example, the first spoiler 210 is triangular or trapezoidal, and the shape of the second spoiler 220 is the same as that of the first spoiler 210 .

[0042] In this embodiment, the first spoiler 210 has a polygonal structure, such as a triangle or a trapezoid, and the second spoiler 220 has the same shape as the first spoiler 210. The polygonal design of the first spoiler 210 and the second spoiler 220, through their corners, causes significant local disturbances in the fluid as it flows through. The changes in the edges cause the fluid flow trajectory to deflect significantly, thereby increasing the shear effect and turbulence intensity of the fluid. In particular, the triangular and trapezoidal geometric shapes can induce local vortices in the corner areas of the spoilers, further promoting mixing of the medium.

[0043] In one embodiment, see Figure 1 As shown, the flow channel 110 extends in a rotational manner along the axial extension direction of the main shaft 100 .

[0044] In this embodiment, the flow channel 110 is designed to rotate and extend along the axis of the main shaft 100, causing the fluid to generate a spiral motion while advancing axially. By rotating the flow channel 110 on the main shaft 100, the fluid's flow path is effectively extended, increasing the contact time and contact area between different media, thereby promoting thorough mixing of the media. Within the rotating flow channel 110, the fluid is also subjected to centrifugal force, resulting in the radial distribution of components of different densities. Components with higher density tend to be closer to the outer wall of the flow channel 110, while components with lower density are concentrated in the central area of the flow channel 110. Simultaneously, due to the changing geometry of the flow channel 110, the flow velocity and direction of the fluid continuously change, generating shear forces. The shear forces act on the radially distributed fluid, disrupting its layered structure and further redispersing the different components. In rotating flow, as turbulence gradually develops, the momentum exchange within the fluid is significantly intensified. The synergistic effects of centrifugal force, shear force, and turbulence improve the mixing efficiency of the multiphase fluid, achieving a highly efficient mixing effect.

[0045] In one embodiment, the mixer is made of plastic.

[0046] In this embodiment, the material of the mixer is a plastic material. Plastic materials deform under the action of external forces and can meet different bending and installation requirements. Since plastic materials have good ductility, the mixer can be adjusted according to the shape of the actual pipeline to adapt to complex installation environments. Plastic materials can maintain structural integrity during deformation, reduce the risk of breakage, and ensure reliability in long-term use. In addition, plastic materials are usually lighter in weight, which helps to reduce the overall weight of the equipment and simplify the installation and maintenance process compared to traditional metal materials. The plastic material may include silicone materials. Silicone materials have good flexibility and durability, can maintain physical properties within a large deformation range, and have a certain chemical resistance, which is suitable for the mixing process of various media. By using silicone materials, the mixer can meet the various needs of actual industrial applications while ensuring flexibility.

[0047] In one embodiment, the mixer further includes a sleeve, the main shaft 100 is disposed in the sleeve, and the flow channel 110 of the main shaft 100 corresponds to the inner wall of the sleeve.

[0048] In this embodiment, the provision of the sleeve simplifies the mixer installation process. When the main shaft 100 and the sleeve are combined into a single unit, the mixer can be directly integrated into existing pipelines or equipment, thereby reducing the installation steps of inserting the main shaft 100 in the mixer into the pipeline and improving operational flexibility and scalability.

[0049] The present application also provides a beverage device, wherein the beverage device includes the above-mentioned mixer.

[0050] In this embodiment, the mixer in the beverage device generates turbulence through the collision and contact of multiple media through the mixing unit 200. When multiple liquids or a combination of liquid and gas pass through the mixer, the mixing unit 200 disrupts the flow of the media, creating turbulence. This turbulence accelerates contact and momentum exchange between the different media, thereby improving mixing efficiency and uniformity. Installing this mixer in the beverage device helps shorten mixing time and improve the overall operating efficiency of the device.

[0051] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, 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.

[0052] The above embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the concept of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be based on the appended claims.
