[0033] The specific embodiments of the utility model will be further illustrated below with reference to the accompanying drawings.

[0034] It is easy to understand that according to the technical scheme of the utility model, the general skilled in the art can replace the various structural modes and implementation modes of each other without changing the utility model spirit, therefore, the following specific embodiments and drawings are only exemplary description of the technical scheme of the utility model, and should not be regarded as the whole or regarded as the limitation or restriction of the utility model technical scheme.

Therefore, these or other orientation terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", "third" are only for description purposes and should not be understood as indicating or implying relative importance.

[0036] In the description of the utility model, it should be pointed out that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium, or the communication inside two components. For ordinary skilled in the art, the above belongs to the specific meaning in the utility model can be understood according to the specific circumstances.

[0037] Referring to Figures 1 to 4 The utility model embodiment discloses a kind of mixed liquid device, including main pipeline 1, secondary pipeline 2 and liquid injection structure, secondary pipeline 2 is communicated on main pipeline 1 and the included angle formed by both forms inclination angle, liquid injection structure is sleeved in secondary pipeline 2 and liquid injection structure extends to main pipeline 1 inside one end close to main pipeline 1, liquid injection structure is used to inject liquid into main pipeline 1, such as Figure 2 As a possible implementation of liquid injection structure, liquid injection structure can include liquid injection column 3 and check valve 21, other forms of liquid injection structure can also be used.

[0038] Among them, since liquid injection structure is sleeved in secondary pipeline 2, and liquid injection structure extends to main pipeline 1 inside one end close to main pipeline 1, pure water in main pipeline 1 can flush the end of liquid injection structure extending to main pipeline 1 in real time, so that concentrated solution injected by liquid injection structure can flow into main pipeline 1 in real time, droplet cannot hang in the end of liquid injection structure, and concentrated solution and pure water can be mixed more uniformly.

[0039] Specifically, concentrated solution can be fruit juice concentrate, coffee concentrate and other concentrate with specific flavor and function.

[0040] In addition, as Figure 1 The main pipe 1 and the auxiliary pipe 2 are connected by a communication mode, and form an inclined angle, for example, 85°, 60°, 30° or 5°, etc. The water flow direction of the pure water in the main pipe 1 is at an acute angle with the liquid injection structure, so that when the pure water of the main pipe 1 flushes the end of the liquid injection structure, it will not generate excessive pressure on the pure water in the main pipe 1. The main pipe 1 is used for conveying pure water, and the liquid injection structure is used for conveying concentrated liquid. Since the included angle between the auxiliary pipe 2 and the main pipe 1 is an acute angle, the concentrated liquid can be smoothly mixed into the main pipe 1. The water flow direction is as shown by the arrow direction in the main pipe 1 and the auxiliary pipe 2 in Figure 1 As a specific implementation manner, a first check valve 21 can also be arranged at the end of the auxiliary pipe 2 to prevent reverse flow. In addition, the liquid injection structure is sleeved in the auxiliary pipe 2 and extends into the main pipe 1 at the end close to the main pipe 1 of the liquid injection structure. The concentrated liquid enters the main pipe 1 through the liquid injection structure and is mixed with the pure water in the main pipe 1.

[0041] Optionally, the main pipe 1 and the auxiliary pipe 2 are connected by an integral molding mode, which has better sealing performance.

[0042] Specifically, the included angle between the auxiliary pipe 2 and the main pipe 1 is an acute angle. In the prior art, the main pipe 1 and the auxiliary pipe are perpendicular to each other. When the water flow of the main pipe 1 passes through the connection point, it will be subjected to a vertical resistance, which will slow down the water flow. By setting the included angle between the auxiliary pipe 2 and the main pipe 1 as an acute angle, the turning resistance of the mixed fluid in the pipe can be reduced, the resistance when the concentrated liquid is mixed into the main pipe 1 is reduced, the fluid dynamic pressure is relieved, and the working efficiency of the liquid mixing device is improved.

[0043] The inclined angle of the auxiliary pipe 2 can make the concentrated liquid accumulated near the first check valve 21 flow down to increase the accuracy of the device conveying the concentrated liquid. As shown by the arrow in Figure 1 The liquid flow direction of the main pipe 1 is consistent with the inclined angle of the auxiliary pipe 2, so that the concentrated liquid flowing out of the auxiliary pipe 2 can flow in the direction of the water flow of the main pipe 1. At the same time, the first check valve 21 is arranged close to the connection between the auxiliary pipe 2 and the main pipe 1 to prevent reverse flow of the liquid.

[0044] Specifically, in one of the embodiments, the liquid injection structure includes a liquid injection column 3 and a first check valve 21. The liquid injection column 3 is sleeved in the auxiliary pipe 2, and the first check valve 21 is connected to the end of the liquid injection column 3 close to the main pipe 1. The concentrated liquid enters from the liquid injection column 3, passes through the first check valve 21 and enters the main pipe 1 to be mixed with the pure water in the main pipe 1.

[0045] Preferably, the first check valve 21 is a duckbill valve, when the concentrated liquid flows from the liquid injection column 3, the pressure of the fluid makes the duckbill valve open to expand, and the fluid can pass through the duckbill valve into the main pipeline 1; when the liquid flows reversely, the external pressure or gravity will act on the opening of the duckbill valve to prevent backflow. Of course, in addition to the duckbill valve, the first check valve 21 can also adopt other structures, and the utility model does not make any limitation here.

[0046] The material of the duckbill valve is silica gel or rubber, silica gel and rubber have good elasticity and plasticity, can adapt to different shapes of valve seat parts, the duckbill valve made of silica gel or rubber material has excellent sealing performance, and can ensure that the concentrated liquid does not leak when flowing forward; and silica gel and rubber material has anti-aging performance, which improves the service life of the duckbill valve.

[0047] In the embodiment, the liquid injection column 3 is provided with a liquid injection channel 31, and the liquid injection column 3 provides more accurate liquid injection control. The radius of the liquid injection channel 31 is adjusted by rotating the liquid injection column 3, so that the concentrated liquid can be accurately measured and delivered, and the accuracy and consistency of the concentrated liquid in the mixing process are ensured. Preferably, the radius of the liquid injection channel 31 is 0.1mm-20mm. The radius of the liquid injection channel 31 will directly affect the flow rate of the liquid in the pipeline, and the radius range of 0.1mm-20mm can adapt to different flow rate requirements in application scenarios. Secondly, by selecting an appropriate radius range, the accuracy of liquid delivery is improved, and the accurate injection of concentrated liquid in the mixing process is ensured. The liquid injection channel 31 with a smaller radius can help reduce the risk of air bubbles generated when the liquid flows; in some application scenarios where solid particles exist in the liquid, the liquid injection channel 31 with a larger radius can effectively prevent the liquid from being blocked in the pipeline, and improve the stability and reliability of the liquid injection channel 31.

[0048] Further, the inner wall of the secondary pipeline 2 is provided with a stepped surface 22, the stepped surface 22 is used to abut against the first check valve 21, so as to limit the movement of the first check valve 21 towards the main pipeline 1, and prevent the first check valve 21 from falling off the inner wall of the secondary pipeline 2, and the structure is more stable.

[0049] The liquid injection column 3 is provided with a through hole 32, the outer wall of the secondary pipeline 2 is provided with a lug 23, and the end of the lug 23 away from the main pipeline is provided with a threaded hole 24; in addition, the liquid mixing device further comprises a threaded connecting piece, the threaded connecting piece is sleeved on the through hole 32 and is threadedly connected to the threaded hole 24, so that the liquid injection column 3 and the lug 23 are fixedly connected, and the structure is more firm.

[0050] Preferably, in some embodiments of the present application, the angle between the secondary pipeline 2 and the main pipeline 1 ranges from 5° to 85°, and the liquid injection structure is set in the secondary pipeline 2, i.e., an angle is formed between the liquid injection structure and the main pipeline 1. When the concentrated liquid flows into the main pipeline 1 from the liquid injection structure, the flow direction of the concentrated liquid forms an acute angle with the flow direction of the pure water in the main pipeline 1, reducing the resistance when the concentrated liquid mixes with the pure water.

[0051] Preferably, the angle between the secondary pipeline 2 and the main pipeline 1 ranges from 30° to 60°. Specifically, within the angle range of 30° to 60°, the concentrated liquid is more easily guided by the pure water during mixing, reducing the accumulation of concentrated liquid in the pipeline. This helps to ensure uniform distribution of the fluid and improves the accuracy and controllability of mixing. Within this angle range, the first check valve 21 can be more effective because the fluid is more likely to remain on the side of the first check valve 21, reducing the likelihood of backflow and improving the accuracy of delivering the concentrated liquid.

[0052] In addition, as shown in Figure 4 The present application also provides a liquid mixing system comprising the above liquid mixing device 7, which further comprises a liquid storage bottle 4 and a peristaltic pump 5. The two ends of the peristaltic pump 5 are respectively connected to the liquid storage bottle 4 and the secondary pipeline 2 of the liquid mixing device 7.

[0053] Specifically, the liquid storage bottle 4 is a container for storing concentrated liquid, and the peristaltic pump 5 is a special pump for delivering liquid. Its working principle is to continuously squeeze and release the pipeline to push the liquid. In the liquid mixing system, the peristaltic pump 5 functions to draw concentrated liquid from the liquid storage bottle 4 and deliver it to the liquid mixing device.

[0054] Preferably, in the present embodiment, the liquid mixing system further comprises a second check valve 6, which is arranged between the peristaltic pump and the liquid mixing device. The second check valve 6 prevents the concentrated liquid from flowing back into the peristaltic pump 5 or the liquid storage bottle 4 when not needed, ensuring the stability and flow direction of the liquid mixing system. In addition, backflow of concentrated liquid can cause contamination or damage to the equipment, and the second check valve 6 protects the components within the liquid mixing system from damage, improving the service life of the liquid mixing system.

[0055] The above is only the principle and preferred embodiment of the present application. It should be noted that for those skilled in the art, on the basis of the principle of the present application, a number of other variants can also be made, which should also be considered as the protection scope of the present application.
