[0031] FIG1 shows an existing water outlet device. A water outlet pipe 1 is installed inside the water outlet device, and the water outlet pipe 1 is connected to the water outlet 11, and the axis of the water outlet pipe 1 is perpendicular to the axis of the water outlet 11. A water pump is provided at one end of the water outlet pipe 1 away from the water outlet 11, and the water pump can pump the liquid inside the water outlet device to the water outlet 11 through the water outlet pipe 1. However, since the angle between the axis of the water outlet pipe 1 and the axis of the water outlet 11 is 90°, when the liquid is pumped along the axis of the water outlet pipe 1 to the connection between the water outlet pipe 1 and the water outlet 11 (its movement direction is the direction indicated by the arrow a in FIG1 , hereinafter referred to as direction a), the running direction of the liquid needs to make a 90° turn and move along the axis of the water outlet 11 (its movement direction is the direction indicated by the arrow b in FIG1 , hereinafter referred to as direction b). The specific process of the liquid completing the turning at the connection between the water outlet pipe 1 and the water outlet 11 is as follows: the pumped liquid The liquid first hits the inner wall of one end of the outlet pipe 1 connected to the water outlet 11 along direction a (marked at C in Figure 1). Most of the liquid slows down suddenly due to the impact and scatters. However, due to the push of the subsequent liquid, the decelerated liquid is re-accelerated and flows out along direction b. As shown in Figure 1, a confluence groove is also provided on the top of the water outlet 11. The confluence groove can converge the decelerated liquid. However, since the flow path of the water outlet 11 is short, some of the liquid that is impacted and redirected still has impact stress in various directions after flowing out of the water outlet 11, which causes the liquid to be loose and unstable after flowing out of the water outlet 11. When the user uses a container to collect the flowing liquid, it is very easy to cause water droplets to splash out of the container.

[0032] The loose state of the liquid after flowing out of the water outlet 11 is not a phenomenon that only occurs when the axis of the water outlet pipe 1 is perpendicular to the axis of the water outlet 11. Most water will produce this phenomenon after it is turned and flows out of the outlet. Moreover, when the water pressure is large enough, even if the water is not turned, when the water flows out of the outlet of the pipe, the water will still be in a loose state due to the large internal stress.

[0033] Based on the above-mentioned defects, the present application proposes a water flow clustering faucet.

[0034] It should be noted that Figure 2 shows a cross-sectional view of the water flow bundle type faucet cut vertically downward along one of its own diameters, and the "up" and "down" directions shown in Figure 2 are the "up" and "down" directions described in the following embodiments.

[0035] Please refer to Figures 2 and 3, which show a water flow bundling type faucet, which is provided with a flow hole 5 for water to pass through, and the water flow bundling type faucet includes a water flow bundler 2 and a water outlet 3.

[0036] The water flow bundler 2 includes a tubular body 21 and a flow guide channel 22 formed in the tubular body 21 .

[0037] Specifically, the guide channel 22 penetrates the tubular body 21 from top to bottom, and the water flowing into the water flow bundler 2 flows out of the water flow bundler 2 through the guide channel 22 .

[0038] Optionally, the tubular body 21 is in the shape of a circular tube, and the number of guide channels 22 is multiple. Adjacent guide channels 22 are separated by a guide bar 23. One side of the guide bar 23 is fixedly connected to the inner wall of the tubular body 21, and the side of the guide bar 23 away from the inner wall of the tubular body 21 is oriented toward the axis of the tubular body 21. Optionally, the guide bar 23 is in the shape of a sheet, such as a rectangular sheet. The guide bar 23 and the tubular body 21 can be integrally formed.

[0039] The number of the flow guide channels 22 can be appropriately increased or decreased according to the designed flow rate in the water flow bundler 2. In this embodiment, the number of the flow guide channels 22 is six. Accordingly, the number of the flow guide bars 23 is also six.

[0040] The guide strip 23 has a certain blocking effect on the water entering the water flow bundler, which may prevent the water from passing smoothly through the tubular body 21. Therefore, an oblique angle 231 is formed on the upper edge of the guide strip 23 close to the axis of the tubular body 21. The oblique angle 231 gradually tilts downward along the direction from the inner wall of the tubular body 21 to the axis of the tubular body 21, so that water can pass smoothly through the tubular body 21.

[0041] In actual use, the diversion channel 22 serves to divert the water flow, helping to reduce its pressure and speed. The diversion strips 23 can also block the water to a certain extent. After being blocked by the diversion strips 23, the diverted water can further release the stress generated in the direction different from the direction b due to the impact. Therefore, when the water flows through the diversion channel 22, its pressure is reduced and the speed is reduced, further reducing the stress generated in the water in the direction different from the direction b.

[0042] Continuing with Figure 2, the outlet portion 3 includes a receiving groove 31 and a pressure-reducing channel 32. The shape of the water flow bundler 2 matches the receiving groove 31 and is accommodated within it. The flow guide channel 22 connects with the pressure-reducing channel 32 to form the flow hole 5 of the water flow bundler faucet.

[0043] Specifically, the water outlet 3 is cylindrical. A receiving tank 31 is located at the upper portion of the water outlet 3, and a pressure-reducing channel 32 is located at the lower portion. The receiving tank 31 and the pressure-reducing channel 32 are coaxially arranged and interconnected. After the water bundler 2 is installed in the receiving tank 31, the tubular body 21, the receiving tank 31, and the pressure-reducing channel 32 are coaxial. The opening of the diversion channel 22 at the lower end of the tubular body 21 is aligned with and connected to the pressure-reducing channel 32, ensuring that water flowing out of the diversion channel 22 flows directly into the pressure-reducing channel 32.

[0044] The water-flow-bundling faucet provided in this embodiment of the present application is designed to be installed with other equipment for shared use. To ensure a tight seal when installed on other equipment, an annular mounting groove 33 is provided on the outside of the water outlet 3. A sealing element, such as a sealing ring, can be installed in the mounting groove 33. There can be multiple mounting grooves 33, spaced sequentially from top to bottom on the outside of the water outlet 3. In this embodiment, there are two mounting grooves 33.

[0045] The upper edge of the tubular body 21 extends in a direction away from the axis of the tubular body 21 to form an edge protrusion 4. At this time, the upper end of the edge protrusion 4 is the upper end of the entire tubular body 21.

[0046] Optionally, the upper end of the tubular body 21 is flush with the upper end of the water outlet 3 , or the upper end of the tubular body 21 is lower than the upper end of the water outlet 3 .

[0047] Specifically, if the upper end of the tubular body 21 is higher than the upper end of the water outlet 3, that is, if the axial length of the tubular body 21 is greater than the depth of the receiving groove 31, water flowing from other equipment into the tubular body 21 is likely to flow into the gap between the tubular body 21 and the inner wall of the receiving groove 31, thereby causing water to leak from the gap between the tubular body 21 and the inner wall of the receiving groove 31. Therefore, in the embodiment of the present application, the upper end of the tubular body 21 is flush with the upper end of the water outlet 3, which can be understood as the axial length of the tubular body 21 being less than the depth of the receiving groove 31. Alternatively, the upper end of the tubular body 21 is lower than the upper end of the water outlet 3, which can be understood as the axial length of the tubular body 21 being equal to the depth of the receiving groove 31. For example, in actual applications, the upper end of the tubular body 21 is flush with the upper end of the water outlet 3, thereby reducing the possibility of water entering the gap between the outer side of the tubular body 21 and the inner wall of the receiving groove 31, thereby facilitating the stable flow of water from the diversion channel 22 into the pressure relief channel 32.

[0048] In actual use, the water flows from the guide channel 22 into the pressure-reducing flow channel 32 and is further depressurized and decelerated, so that the water is less likely to splash after flowing out of the pressure-reducing flow channel 32 .

[0049] To sum up, a water flow bundling type faucet of the present application weakens the stress generated inside the water in a direction different from the direction b by setting a guide strip 23 and a guide channel 22, and further reduces the pressure and slows down the water through the pressure reducing channel 32, so that when the water flows out of the water flow bundling type faucet, it is less likely to splash, and the formed water column is more stable.

[0050] Optionally, as shown in FIG4 , a guide column 24 is provided in the tubular body 21 , the guide column 24 is coaxially arranged with the tubular body 21 , and the side of each guide strip 23 facing away from the inner wall of the tubular body 21 is fixedly connected to the guide column 24 .

[0051] More specifically, the tubular body 21 , the guide strip 23 and the guide post 24 are integrally formed.

[0052] In actual use, the guide column 24 further reduces the flow area of ​​the diversion channel 22, further enhancing the water obstruction effect of the water flow concentrator 2, and further helping to reduce splashing when water flows out of the water flow concentrator 2. However, the guide column 24 also weakens the water pressure and speed reduction effect of the water flow concentrator 2. Therefore, in this embodiment, the length of the pressure-reducing channel 32 can be appropriately increased to enhance the pressure-reducing and speed-reducing effect of the pressure-reducing channel 32.

[0053] Please refer to Figures 5-7. Optionally, the lower end of the guide column 24 in the embodiment of the present application extends downward along the axis of the tubular body 21 to form a guide portion 25. When the tubular body 21 is installed in the accommodating groove 31, the guide portion 25 extends into the pressure reducing channel 32.

[0054] The lower end of the guide portion 25 is formed into a hemispherical shape, so that water can be more easily separated from the guide portion 25 at the lower end, thereby reducing the flow disorder of water when it leaves the lower end of the guide portion 25.

[0055] The function of the guide portion 25 is to guide water into the pressure reducing flow channel 32 to avoid the flow disorder of the water caused by the difference in flow area between the guide channel 22 and the pressure reducing flow channel 32 .

[0056] The upper side of each guide bar 23 is a curved surface 232, which gradually sinks downward along the inner wall of the tubular body 21 to the axis of the tubular body 21. Specifically, the vertex of the arc corresponding to the curved surface 232 is lower than the upper end of the tubular body 21.

[0057] The water blocking effect of the guide strip 23 is too strong, which may cause water to be unable to pass smoothly through the tubular body 21. Therefore, the upper side of the guide strip 23 is set to an arc surface 232 so that water can pass smoothly through the tubular body 21.

[0058] In the above embodiment, when water flows through diversion channel 22, diversion channel 22 acts as a buffer, reducing pressure and speed. When water flows through pressure-reducing channel 32, pressure-reducing channel 32 further reduces pressure and speed, primarily reducing the isotropic stress within the water. To ensure the pressure-reducing and speed-reducing effects of pressure-reducing channel 32, the combined flow area of ​​the multiple diversion channels is smaller than the flow area of ​​the pressure-reducing channel.

[0059] When the decompression and deceleration effect of the flow channel 22 on the water is weak, the stress in the water needs to be fully released through the pressure-reducing channel 32. When the decompression and deceleration effect of the flow channel 22 is strong, the stress in the water is released more easily. Since the length of the water outlet 3 is fixed, if the water flow bundler 2 is to achieve a good and stable bundling effect in the device, the design of the ratio of the length of the flow channel 22 to the pressure-reducing channel 32 (hereinafter referred to as ratio A) and the ratio of the cross-sectional area occupied by the flow channel 22 to the cross-sectional area occupied by the pressure-reducing channel 32 (hereinafter referred to as ratio B) are particularly important. The ratio A ranges from 3:10 to 3:1, while the ratio B ranges from 9:15 to 14:15. In the actual design process, the ratio A and the ratio B are in direct proportion.

[0060] For example, in the first embodiment of the present application, the ratio A is 1125:2295, and the ratio B is 11112:14076. In the second embodiment of the present application, the ratio A is 900:2520, and the ratio B is 9582:14076.

[0061] The present application also discloses a device that uses the above-mentioned water flow clustering nozzle, and the device can be any one of a milk mixer, a soy milk maker, a water dispenser and a water purifier.

[0062] By using the water flow converging faucet 2, the flow state of water flowing out of the device is more stable, and when water is taken out of the device, the water is less likely to splash out of the container.

[0063] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical concepts disclosed in this application shall be covered by the claims of this application.
