[0043] The objectives, features, and advantages of this document will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of this document clearer, the embodiments described below will be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined arbitrarily.

[0045] Existing liquid dispensing systems with cleaning fluid discharge function generally use manual squeezing or electric mechanism to squeeze out the cleaning fluid and manually apply it to the items to be cleaned. The amount of cleaning fluid is not easy to control and it is not easy to apply it evenly to the items to be cleaned, causing inconvenience to users.

[0046] To address the aforementioned technical problems, this embodiment provides a liquid mixing device and a liquid dispensing system. This liquid dispensing system can be installed in various environments such as companies, schools, homes, and factories to achieve the cleaning treatment of items to be cleaned, thereby improving people's quality of life and health.

[0047] Please combine them together Figure 1 , Figure 2 and Figure 5 The liquid dispensing system provided in this embodiment will now be described. This liquid dispensing system includes a mixing device, a water supply component, and a liquid supply component. The mixing device includes a body assembly 10 and a control mechanism 20. The body assembly 10 is provided with a first flow channel 100, a second flow channel 200, and a mixing flow channel 300. The first flow channel 100 and the second flow channel 200 communicate with the mixing flow channel 300. The first flow channel 100 is configured to provide space through which a first fluid flows. The second flow channel 200 is configured to provide space through which a second fluid flows. The mixing flow channel 300 can form a discharge port 400 on the body assembly 10. The control mechanism 20 is movably disposed on the body assembly 10. The control mechanism 20 is movable relative to the main body assembly 10 to communicate the second flow channel 200 with the mixing flow channel 300. This allows the negative pressure generated when the first fluid passes through the first flow channel 100 and the mixing flow channel 300 is discharged from the outlet 400 to drive the second fluid located in the second flow channel 200 into the mixing flow channel 300, or to disconnect the second flow channel 200 from the mixing flow channel 300. A water supply assembly is configured to supply the first fluid to the first flow channel 100. The water supply assembly may be, but is not limited to, a manually or electrically controlled valve structure. Opening or closing the water supply assembly connects or disconnects the first flow channel 100 from the first fluid source. A liquid supply assembly is configured to supply the second fluid to the second flow channel 200. The liquid supply assembly has a receiving cavity communicating with the second flow channel 200. The second fluid is contained in the receiving cavity. The first fluid includes, but is not limited to, clean water or pure water from a municipal water network. The second fluid is a cleaning fluid, including, but not limited to, a solution or solid particles containing cleaning components. The liquid outlet system also includes a housing, with the water supply assembly and the liquid supply assembly disposed within the housing. The mixing device is exposed in the outer casing.

[0048] In summary, implementing the embodiments described herein will have the following beneficial effects: The mixing device described above, when applied to a liquid outlet system, not only enables the system to possess excellent cleaning efficiency, but also allows it to discharge the cleaning fluid (second fluid) without manual squeezing or electric mechanism drive. After mixing with clean water (first fluid), the fluid is discharged more evenly from the outlet system, and the amount of cleaning fluid is easily controlled, facilitating user operation. Furthermore, the mixing device is modular and miniaturized, making it easy to replace existing structures in the liquid outlet system or install it at the outlet of an existing system. Specifically, the mixing device includes a body assembly 10 with a first flow channel 100, a second flow channel 200, and a mixing flow channel 300, and a control mechanism 20 movably mounted on the body assembly 10. The control mechanism 20 can move relative to the main body assembly 10 to connect the second flow channel 200 with the mixing flow channel 300. This allows the negative pressure generated when the first fluid passes through the first flow channel 100 and the mixing flow channel 300 exits through the outlet 400 to drive the second fluid located in the second flow channel 200 into the mixing flow channel 300. The second fluid then mixes more evenly with the first fluid before being discharged and adhering to the items to be cleaned. When the amount of the second fluid meets the cleaning requirements, the control mechanism 20 can again move relative to the main body assembly 10 to disconnect the second flow channel 200 from the mixing flow channel 300, preventing the second fluid from continuing to mix with the first fluid. This controls the amount of the second fluid while facilitating the switching of the liquid discharge system to the first fluid to complete the final cleaning operation.

[0049] In one embodiment, please combine Figure 2 , Figure 3 , Figure 5 and Figure 6 The first flow channel 100 includes an inlet section 101 and an acceleration section 102. The acceleration section 102 connects the inlet section 101 and the mixing flow channel 300, and the cross-sectional area of ​​the acceleration section 102 is smaller than that of the inlet section 101. By setting the acceleration section 102 in this way, the flow velocity of the first fluid entering the acceleration section 102 from the inlet section 101 can be accelerated by reducing the cross-sectional area, further increasing the negative pressure value and ensuring that the second fluid can be stably drawn into the mixing flow channel 300.

[0050] In one embodiment, please combine Figure 3 and Figure 6 The first flow channel 100 also includes a converging section 103, the larger end of which is connected to the inlet section 101, and the smaller end of which is connected to the acceleration section 102. This allows the first fluid to flow more smoothly from the inlet section 101 to the acceleration section 102, which has a smaller cross-sectional area, thus preventing vibration and abnormal noise in the mixing device during the flow of the first fluid and improving the user experience. At the same time, the converging section 103 can also shrink and gather the first fluid, reducing turbulence and making the flow direction of the first fluid more stable.

[0051] In one embodiment, please combine Figure 2 , Figure 3 , Figure 5 and Figure 6 The mixing channel 300 includes a mixing section 301 and a discharge section 302. The first flow channel 100 and the second flow channel 200 are connected to the mixing section 301, and the discharge section 302 is connected between the mixing section 301 and the discharge outlet 400. This allows the first and second fluids to mix in the mixing section 301, pass through the discharge section 302, and be discharged from the discharge outlet 400. The discharge section 302 can rectify the flow of the mixed aqueous solution, giving it a certain directionality. The cross-sectional area of ​​the discharge section 302 gradually increases from the mixing section 301 to the discharge outlet 400, resulting in a larger outlet surface area and a gentler flow.

[0052] In one embodiment, please combine Figure 3 and Figure 6 The mixing channel 300 also includes a throat section 303, the cross-sectional area of ​​which is larger than that of the speed-increasing section 102. This allows the main flow portions of the first fluid and the aqueous solution resulting from the mixture of the first and second fluids to directly enter the throat section 303, thereby reducing the probability of collisions with the body assembly 10 before entering the throat section 303 and enabling the first fluid and the aqueous solution resulting from the mixture of the first and second fluids to enter the throat section 303 more smoothly.

[0053] In one embodiment, please combine Figure 1 , Figure 2 and Figure 5 The mixing device also includes a bubbler 30, which is located at the outlet 400. The bubbler 30 allows the aqueous solution resulting from the mixture of the first and second fluids to absorb air, forming bubbles containing cleaning components. This results in a more even distribution of the cleaning components and their more uniform adhesion to the items being cleaned. Furthermore, by using bubbles to more evenly adhere the cleaning components to the items, the amount of second fluid used can be reduced while still meeting cleaning requirements, thus saving costs. The bubbler 30 can be detachably or fixedly mounted to the main body assembly 10 via the mounting base 40.

[0054] In one embodiment, please combine Figures 1 to 8The control mechanism 20 includes a movable member 21 and a sealing assembly 22. The movable member 21 is provided with a connecting flow channel 500. The connecting flow channel 500 communicates with the mixing flow channel 300. The sealing assembly 22 is disposed on the movable member 21, which is movably disposed on the body assembly 10 and is capable of moving relative to the body assembly 10. During the movement of the movable member 21 relative to the body assembly 10: the connecting flow channel 500 can communicate with the second flow channel 200, thereby connecting the second flow channel 200 with the mixing flow channel 300; or the sealing assembly 22 can cover the second flow channel 200, thereby disconnecting the second flow channel 200 from the mixing flow channel 300. By moving the movable part 21 relative to the main body assembly 10, the second flow channel 200 can be connected to the mixing flow channel 300 through the connecting flow channel 500, ensuring that the second fluid can smoothly enter the mixing flow channel 300; the second flow channel 200 can also be covered by the sealing assembly 22 to prevent the second fluid from entering the mixing flow channel 300, thus controlling the amount of the second fluid used. At the same time, it can also prevent the discharge system from mixing with the cleaning components when switching to the first fluid discharge.

[0055] In one embodiment, please combine Figure 4 , Figures 6 to 8 The connecting channel 500 includes a receiving groove 501 and a slit 502. The slit 502 connects the mixing channel 300 and the receiving groove 501. During the movement of the movable member 21 relative to the body assembly 10, the receiving groove 501 can connect with the second channel 200, so that the second channel 200 is connected to the mixing channel 300. The receiving groove 501 can receive and store the second fluid from the second channel 200, so that the second fluid can be discharged into the mixing channel 300 in a timely manner during the initial stage of the connection between the mixing channel 300 and the second channel 200. The flow area of ​​the slit 502 is relatively small compared with the flow area of ​​the receiving groove 501 and the mixing channel 300, resulting in a greater suction force generated by the negative pressure, ensuring that the second fluid can be discharged into the mixing channel 300 quickly and stably. The receiving groove 501 extends along the movement direction of the movable member 21 to accommodate more of the second fluid, thereby enabling the second fluid to be replenished into the slit 502 in a timely manner, reducing the amount of gas entering the second fluid in the mixing channel 300, and making the dosage of the second fluid more accurate. At the same time, the extension of the receiving groove 501 along the movement direction of the movable member 21 also increases the area of ​​the receiving groove 501 facing the second channel 200, facilitating the smooth flow of the second fluid into the receiving groove 501.

[0056] In one embodiment, please combine Figure 1 , Figure 3 and Figure 8The sealing assembly 22 includes a seal 221 and an elastic element 222. The elastic element 222 is supported between the movable element 21 and the seal 221, and enables the seal 221 to abut against the body assembly 10, improving the stability of the seal 221 in covering the second flow channel 200. The seal 221 can be made of, but is not limited to, rubber, allowing it to elastically abut against the body assembly 10. The seal 221's deformation allows it to better conform to the body assembly 10, further enhancing the stability of covering the second flow channel 200. The elastic element 222 can be, but is not limited to, a metal spring or a plastic spring.

[0057] In one embodiment, please combine Figure 3 and Figure 8 The movable component 21 is provided with a mounting groove 600, and the sealing component 221 and the elastic component 222 are mounted in the mounting groove 600. This increases the connection area between the sealing component 221 and the elastic component 222 and the movable component 21, thereby increasing the connection stability between the sealing component 221 and the elastic component 222 and the movable component 21. The elastic component 222 can drive the sealing component 221 to move along the mounting groove 600 so that the sealing component 221 abuts against the main body assembly 10. Thus, the setting of the mounting groove 600 makes the movement accuracy of the sealing component 221 under the restriction of the movable component 21 higher, ensuring the accuracy of the sealing component 221 covering the second flow channel 200.

[0058] In one embodiment, please combine Figures 1 to 9 The control mechanism 20 also includes a housing 23. The housing 23 is fitted onto the main body assembly 10 and the movable member 21, and can drive the movable member 21 to move relative to the main body assembly 10. This ensures that the movable member 21's position relative to the main body assembly 10 is within the housing 23, protected by the housing 23, preventing external interference with the movement of the movable member 21 relative to the main body assembly 10, and improving the stability of the movement of the movable member 21 relative to the main body assembly 10. The movement of the movable member 21 relative to the main body assembly 10 includes, but is not limited to, linear movement, curvilinear movement, or rotational movement. Similarly, in order to drive the movement of the movable member 21, the housing 23 also has the same or similar movement mode as the movable member 21. In this embodiment, both the movable member 21 and the housing 23 can rotate relative to the main body assembly 10. To improve the rotational stability of the housing 23 relative to the main body assembly 10, the housing 23 is also provided with a first sliding part 231, and the main body assembly 10 is provided with a second sliding part 11 that slides with the first sliding part 231. One of the first sliding part 231 and the second sliding part 11 is a protruding structure, and the other has a matching groove structure.

[0059] In one embodiment, please combine Figure 3 and Figures 8 to 10The movable component 21 is provided with a first transmission part 211, and the housing 23 is provided with a second transmission part 232 that is transmissionly connected to the first transmission part 211. Through the transmission cooperation of the first transmission part 211 and the second transmission part 232, the movable component 21 can move together with the housing 23 inside the housing 23, realizing the connection or disconnection of the second flow channel 200 and the mixing flow channel 300. The main body assembly 10 is provided with a limiting part 12, which is configured to cooperate with one of the first transmission part 211 and the second transmission part 232 to limit the movement range of the movable component 21, facilitating the rapid switching of the connection or disconnection of the second flow channel 200 and the mixing flow channel 300. Simultaneously, the position of the movable component 21 relative to the main body assembly 10 when the second flow channel 200 and the mixing flow channel 300 are connected or disconnected can be set at the stop point of the movable component 21's movement range, making it easy to determine whether the connection or disconnection of the second flow channel 200 and the mixing flow channel 300 is complete. The first transmission part 211 may be a protruding structure, and the second transmission part 232 and the limiting part 12 are provided with groove structures that match the first transmission part 211. It can be understood that in other embodiments, the second transmission part 232 is a protruding structure, and the first transmission part 211 and the limiting part 12 are provided with groove structures that match the second transmission part 232.

[0060] In one embodiment, please combine Figures 1 to 7 and Figure 10 The movable member 21 is rotatably connected to the body assembly 10. The body assembly 10 includes a first connecting member 13 and a second connecting member 14 spaced apart. The movable member 21 is limited and connected between the first connecting member 13 and the second connecting member 14 to restrict the axial and radial movement of the movable member 21 relative to the body assembly 10 along its rotation axis. The first connecting member 13 can be connected to the housing via a connecting structure 15. The connecting structure 15 can be integrally provided with the first connecting member 13 or separately provided. The connecting structure 15 is provided with a connecting portion for connecting to the housing. This connecting portion can be, but is not limited to, a threaded portion, a snap-fit ​​portion, or a plug-in portion. A first flow channel 100 and a second flow channel 200 are provided on the first connecting member 13, and a mixing flow channel 300 is provided on the second connecting member 14 and extends between the first connecting member 13 and the second connecting member 14.

[0061] In one embodiment, please combine Figure 3 , Figure 6 and Figure 8, the second connecting member 14 has a connecting column 141. The movable member 21 is provided with a through hole 700. The movable member 21 is sleeved on the connecting column 141 through the through hole 700 and can rotate relative to the connecting column 141. In this way, the stability of the rotation of the movable member 21 relative to the body assembly 10 can be improved by cooperating with the connecting column 141. The first connecting member 13 further has a circumferential wall 131. The circumferential wall 131 is located on the circumferential outer side of the movable member 21 and can cooperate with the connecting column 141 to further improve the stability of the rotation of the movable member 21 relative to the body assembly 10. Sealing structures are provided between the movable member 21 and the connecting column 141 and between the movable member 21 and the circumferential wall 131. While ensuring sealing, it can also reduce the friction when the movable member 21 rotates relative to the body assembly 10. The mixing flow channel 300 extends through the connecting column 141 to between the first connecting member 13 and the second connecting member 14.

[0062] In one embodiment, please continue to refer to Figure 3 and Figure 6 , the first connecting member 13 has an extension portion 132. The extension portion 132 extends to the through hole 700. In this way, positioning can be achieved by the cooperation of the extension portion 132 and the through hole 700, which is convenient for the assembly among the first connecting member 13, the second connecting member 14 and the movable member 21. The first flow channel 100 extends to the extension portion 132 and is communicated with the mixing flow channel 300.
