Technical Field
[0001] The utility model relates to the technical field of drinking water equipment, and specifically provides a drinking water equipment and a water vapor separation water outlet nozzle thereof. Background Art
[0002] Nowadays, with the continuous improvement of people's living standards, people are constantly pursuing a higher quality of life. Drinking water equipment such as water dispensers and integrated water purifiers and heat pumps have become common electrical appliances in people's lives.
[0003] Drinking water equipment usually has the function of supplying hot water. The water flowing through it is heated by the configured instant heating device, and then flows out through the hot water outlet pipe and is supplied to the user. Since part of the water flowing through the instant heating device will evaporate into high-temperature steam during the heating process, the high-temperature steam will flow out through the outlet of the hot water outlet pipe together with the water flow. When the user uses a cup to hold hot water, the high-temperature steam flowing out from the outlet along with the hot water can easily scald the user. In order to prevent the high-temperature steam from scalding the user, a water vapor separation chamber is provided inside the improved water outlet, and an exhaust pipe separated from the hot water outlet is provided on the water outlet. After the high-temperature steam and hot water are separated in the water vapor separation chamber of the water outlet, the high-temperature steam is discharged through the exhaust pipe, and the hot water flows out from the outlet of the water outlet.
[0004] During daily use, the water inlet temperature and water inlet flow rate will change. In order to meet the different usage requirements of users, the required water outlet temperature also has multiple gears. Therefore, the water outlet flow rate of the existing drinking water equipment equipped with instant heating device is designed to be a wider range (such as 360ml / min-800ml / min). At the same time, in order to ensure the stability of the water type under different water outlet flow rates, the water outlet is equipped with a middle water outlet pipe and a plurality of peripheral water outlet pipes distributed around the middle water outlet pipe. The upper ends (i.e., the water inlet ends) of the plurality of peripheral water outlet pipes are all higher than the upper end (i.e., the water inlet end) of the middle water outlet pipe. When the water flow rate is small, the water level in the water vapor separation chamber cannot reach the upper end position of the peripheral water outlet pipe, and the hot water can only flow out from the middle water outlet pipe. When the water flow rate is large, the water level in the water vapor separation chamber is higher than the upper end position of the peripheral water outlet pipe, part of the hot water flows out from the middle water outlet pipe, and the other part of the hot water flows out from the peripheral water outlet pipe. The hot water flowing out of the peripheral water outlet pipe and the hot water flowing out of the middle water outlet pipe form a water column.
[0005] The inventor of the utility model found that when a large water flow is discharged from the water outlet of the above structure, the water column suddenly thickens within a short period of time from the beginning of water discharge, and part of the water is thrown out with the sudden change of the water column. The inventor of the utility model found through repeated experiments and analysis that within a period of time after the hot water mixed with high-temperature water vapor begins to enter the water vapor separation chamber, part of the separated hot water flows out from the middle water outlet pipe, and the water level in the water vapor separation chamber continues to rise. When the water level rises to the upper end of the peripheral water outlet pipe, the water film on the liquid surface does not break due to the tension of the water, and the water does not flow from the upper end of the peripheral water outlet pipe into the peripheral water outlet pipe. After that, the water level continues to rise. When the water level is 2-4 mm higher than the upper end of the outer water outlet pipe, the water film on the liquid surface breaks. Since the water level is 2-4 mm higher than the upper end of the outer water outlet pipe, a large amount of water instantly flows into the outer water outlet pipe. A water flow with the same cross-sectional size as its internal channel is instantly formed in the outer water outlet pipe. After flowing out from the lower end of the outer water outlet pipe, the water flow converges into one water flow with the water flow of the middle water outlet pipe, causing the outlet water flow to suddenly increase, and part of the water is thrown to the surroundings in the form of droplets.
[0006] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content
[0007] The utility model aims to solve the above technical problem, namely, to solve the problem that the water column of the existing water outlet suddenly thickens within a short period of time when a large amount of water is discharged, and part of the water is thrown out to the surroundings.
[0008] In a first aspect, the utility model provides a water vapor separation nozzle of a drinking water device, wherein the water vapor separation nozzle comprises a shell, wherein a water vapor separation chamber is provided in the shell, and a water inlet and an exhaust port connected to the water vapor separation chamber are arranged on the shell, and a first water outlet pipe and a second water outlet pipe extending from top to bottom are also arranged at the bottom of the shell, and the second water outlet pipe is arranged so that the water flowing out of the second water outlet pipe merges into the water flowing out of the first water outlet pipe, and the water inlet sections of the first water outlet pipe and the second water outlet pipe are both inserted into the water vapor separation chamber, the lower end of the water inlet section of the second water outlet pipe is higher than the upper end of the water inlet section of the first water outlet pipe, and the effective flow area of the water inlet section of the second water outlet pipe increases with increasing height.
[0009] In the preferred technical solution of the above-mentioned water vapor separation water nozzle, the vertical channel of the second water outlet pipe passes through its upper end face along its axis; the height of the upper end face of the second water outlet pipe increases continuously or intermittently at different positions from the first side to the second side, or the upper end face of the second water outlet pipe is sequentially distributed with a first part and a second part from the first side to the second side, the second part is a plane, and the height of the first part increases continuously or intermittently at different positions from the first side to the second side, so that the effective flow area of the water inlet section of the second water outlet pipe increases with increasing height.
[0010] In the preferred technical solution of the above-mentioned water vapor separation nozzle, a plurality of through holes are arranged on the side wall of the second water outlet pipe, and the plurality of through holes are distributed in the vertical direction and the cross-sectional area of the higher through holes is larger than the cross-sectional area of the lower through holes, so that the effective flow area of the water inlet section of the second water outlet pipe increases with the increase of height.
[0011] In the preferred technical solution of the above-mentioned water vapor separation water outlet nozzle, the sum of the cross-sectional areas of the multiple through holes on the second water outlet pipe is not greater than the minimum cross-sectional area of the second water outlet pipe.
[0012] In the preferred technical solution of the above-mentioned water vapor separation nozzle, a long strip-shaped opening is provided on the side wall of the second water outlet pipe, the length direction of the opening is along the vertical direction, and the width of the opening gradually increases from bottom to top, so that the effective flow area of the water inlet section of the second water outlet pipe increases with increasing height.
[0013] In the preferred technical solution of the above-mentioned water vapor separation water outlet nozzle, there are multiple second water outlet pipes, and the water inlet sections of the multiple second water outlet pipes are respectively within a height range that does not overlap with each other.
[0014] In the preferred technical solution of the above-mentioned water vapor separation water outlet nozzle, the water vapor separation water outlet nozzle also includes a confluence pipe, the number of the second water outlet pipes is multiple, the lower end outlets of the multiple second water outlet pipes are all connected to the confluence pipe, the confluence pipe is sleeved on the outside of the first water outlet pipe, and a confluence channel is formed between the confluence pipe and the first water outlet pipe.
[0015] In the preferred technical solution of the above-mentioned water vapor separation nozzle, the inner wall of the confluence pipe is connected with a necked pipe extending from top to bottom near the lower end, and the outlet of the confluence channel is formed between the lower end of the necked pipe and the first water outlet pipe; or the lower end of the confluence pipe is connected with a necked pipe extending from top to bottom, and the outlet of the confluence channel is formed between the lower end of the necked pipe and the first water outlet pipe.
[0016] In the preferred technical solution of the above-mentioned water vapor separation water outlet nozzle, the vertical channel of the second water outlet pipe includes a necking section extending from top to bottom and a first equal-diameter section and a second equal-diameter section respectively connected to the upper and lower ends of the necking section.
[0017] In the preferred technical solution of the above-mentioned water vapor separation water outlet nozzle, a semi-cylindrical baffle is extended downwardly from the lower end of the first water outlet pipe on the side away from the water inlet.
[0018] In the case of adopting the above technical solution, the water vapor separation nozzle of the drinking water equipment includes a shell, a water vapor separation chamber is provided in the shell, a water inlet and an exhaust port connected to the water vapor separation chamber are arranged on the shell, and a first water outlet pipe and a second water outlet pipe extending from top to bottom are also arranged at the bottom of the shell, and the second water outlet pipe is arranged so that the outflowing water flows into the water flow outflowing from the first water outlet pipe, and the water inlet sections of the first water outlet pipe and the second water outlet pipe are both inserted into the water vapor separation chamber, and the lower end of the water inlet section of the second water outlet pipe is higher than the upper end of the water inlet section of the first water outlet pipe, and the effective flow area of the water inlet section of the second water outlet pipe increases with the increase of height. It should be noted that the "water inlet section" refers to the pipe section on the water outlet pipe having an opening connecting its internal channel and the water vapor separation chamber. The "effective flow area of the water inlet section of the second water outlet pipe" refers to the total cross-sectional area of the water flow in the water vapor separation chamber flowing into the water inlet section of a single second water outlet pipe at the current water level.
[0019] With the water vapor separation nozzle of the above structure, when a large water flow flows out of the water vapor separation nozzle, within a period of time after the hot water mixed with high-temperature water vapor begins to enter the water vapor separation chamber, a part of the separated hot water flows out from the first water outlet pipe, and the water level in the water vapor separation chamber continues to rise. When the water level rises to the lowest position of the water inlet section of the second water outlet pipe, as the water level continues to rise, after the water film on the liquid surface breaks, the water flow rate flowing into the water inlet section of the second water outlet pipe is also relatively small, and the water flow rate flowing out of the second water outlet pipe is also relatively small. The water flow flowing out of the second water outlet pipe merges with the water flow flowing out of the first water outlet pipe into a water column, and the water flow of the water column does not change much. As the liquid level continues to rise, the water flow rate flowing into the water inlet section of the second water outlet pipe continues to increase, and the water flow flowing out of the second water outlet pipe also continues to increase. The water column formed by the water flow flowing out of the second water outlet pipe and the water flow flowing out of the first water outlet pipe continues to increase, and finally when the water level in the water vapor separation box reaches a stable state, the water flow of the water column remains in a stable state. This arrangement reduces the risk of the water column suddenly thickening in a short period of time when the water outlet starts to discharge a large amount of water, causing part of the water to be thrown around and easily scalding the user, thereby optimizing the user experience.
[0020] Preferably, the vertical channel of the second water outlet pipe passes through its upper end surface along its axis; the height of the upper end surface of the second water outlet pipe increases continuously or intermittently at different positions from the first side to the second side, or the upper end surface of the second water outlet pipe is sequentially distributed with a first part and a second part from the first side to the second side, the second part is a plane, and the height of the first part increases continuously or intermittently at different positions from the side away from the second part to the side close to the second part, so that the effective flow area of the water inlet section of the second water outlet pipe increases with increasing height.
[0021] Through such an arrangement, it is possible to easily realize that the effective flow area of the water inlet section of the second water outlet pipe increases with the increase of height, and the structure is simple and easy to manufacture.
[0022] Preferably, a plurality of through holes are provided on the side wall of the second water outlet pipe, and the plurality of through holes are distributed in the vertical direction and the cross-sectional area of the higher through holes is larger than the cross-sectional area of the lower through holes, so that the effective flow area of the water inlet section of the second water outlet pipe increases with increasing height.
[0023] Through such an arrangement, it is also possible to achieve that the effective flow area of the water inlet section of the second water outlet pipe increases with the increase in height, and the structure is relatively simple.
[0024] Preferably, a long strip opening is provided on the side wall of the second water outlet pipe, the length direction of the opening is along the vertical direction, and the width of the opening gradually increases from bottom to top, so that the effective flow area of the water inlet section of the second water outlet pipe increases with increasing height.
[0025] With such a configuration, the effective flow area of the water inlet section of the second water outlet pipe gradually increases with the increase of height. When in use, as the water level in the water vapor separation chamber gradually rises, the water flow into the second water outlet pipe will gradually increase with the increase of the water level, so that the water flow out of the second water outlet pipe gradually increases, and then the water column formed by the water flow out of the second water outlet pipe and the water flow out of the first water outlet pipe gradually becomes thicker, which more effectively reduces the risk of the water column suddenly becoming thicker and part of the water being thrown out to the surroundings, which may easily scald the user.
[0026] Preferably, there are multiple second water outlet pipes, and the water inlet sections of the multiple second water outlet pipes are respectively within a height range that does not overlap with each other.
[0027] This arrangement can effectively prolong the time it takes for the mixed water column to change from the thinnest state to the thickest state, thereby more effectively reducing the risk of the water column suddenly becoming thicker and part of the water being thrown out to the surroundings, which can easily scald the user. In addition, this can also adapt to drinking water equipment with a wider water flow range.
[0028] Preferably, the water vapor separation nozzle also includes a confluence pipe, there are multiple second water outlet pipes, the lower end outlets of the multiple second water outlet pipes are all connected to the confluence pipe, the confluence pipe is sleeved on the outside of the first water outlet pipe, and a confluence channel is formed between the confluence pipe and the first water outlet pipe.
[0029] Through such an arrangement, the water flows out of multiple second water outlet pipes are first merged and then merged with the water flow out of the first water outlet pipe, which is more conducive to the merging of the water flow out of the second water outlet pipe and the water flow out of the first water outlet pipe, optimizes the water shape of the outlet water column, and more effectively reduces the risk of water droplets splashing.
[0030] Preferably, the inner wall of the confluence pipe is connected to a necked pipe extending from top to bottom near the lower end, and an outlet of the confluence channel is formed between the lower end of the necked pipe and the first water outlet pipe; or the lower end of the confluence pipe is connected to a necked pipe extending from top to bottom, and an outlet of the confluence channel is formed between the lower end of the necked pipe and the first water outlet pipe.
[0031] Through such an arrangement, when the flow rate of water flowing into the second water outlet pipe is small, the water shape of the second water outlet pipe can be better guaranteed, which is conducive to the confluence of the water flow out of the second water outlet pipe with the water flow out of the first water outlet pipe, further reducing the risk of water droplets splashing.
[0032] Preferably, the vertical channel of the second water outlet pipe includes a necking section extending from top to bottom and a first equal-diameter section and a second equal-diameter section respectively connected to the upper and lower ends of the necking section.
[0033] With such an arrangement, the risk of water droplets splashing due to a poor water pattern of the water flowing out of the second water outlet pipe when the water flow entering the second water outlet pipe is small can be reduced.
[0034] Preferably, a semi-cylindrical baffle is extended downwardly from the lower end of the first water outlet pipe on a side away from the water inlet.
[0035] The inventor of the utility model found that when only the first water outlet pipe is discharging water, the water flow out of the lower end of the first water outlet pipe occasionally has a bad water shape and part of the water is thrown out. After continuous attempts by the inventor, the inventor found that a semi-cylindrical baffle extends downward on the side away from the water inlet at the lower end of the first water outlet pipe, which can avoid the situation that when only the first water outlet pipe is discharging water, the water flow out of the lower end of the first water outlet pipe occasionally has a bad water shape and part of the water is thrown out.
[0036] In a second aspect, the utility model further provides a drinking water device, which includes a water vapor separation nozzle according to any one of the above technical solutions.
[0037] It should be noted that the drinking water equipment has all the technical effects of the water vapor separation nozzle described in any of the above technical solutions, which will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] First, those skilled in the art should understand that the embodiments described below are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.
[0049] It should be noted that in the description of the utility model, the terms "left", "right" and other terms indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the utility model. In addition, the terms "first", "second" and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0050] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, a direct connection, or an indirect connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0051] Based on the problem that the existing water outlet mentioned in the background technology suddenly thickens the water column in a short time when a large amount of water is discharged, and part of the water is thrown out to the surroundings, the utility model provides a water vapor separation water outlet of a drinking water device, the water vapor separation water outlet comprises a shell, a water vapor separation chamber is provided in the shell, a water inlet and an exhaust port connected to the water vapor separation chamber are arranged on the shell, and a first water outlet pipe and a second water outlet pipe extending from top to bottom are also arranged at the bottom of the shell, the second water outlet pipe is arranged so that the outflowing water flow merges into the water flow outflowing from the first water outlet pipe, the water inlet sections of the first water outlet pipe and the second water outlet pipe are both inserted into the water vapor separation chamber, the lower end of the water inlet section of the second water outlet pipe is higher than the upper end of the water inlet section of the first water outlet pipe, and the effective flow area of the water inlet section of the second water outlet pipe increases with the increase of height. It should be noted that the "water inlet section" refers to the pipe section on the water outlet pipe having an opening connecting its internal channel and the water vapor separation chamber.
[0052] When a large water flow flows out of the water vapor separation nozzle, within a period of time after the hot water mixed with high-temperature water vapor begins to enter the water vapor separation chamber, a part of the separated hot water flows out from the first water outlet pipe, and the water level in the water vapor separation chamber continues to rise. When the water level rises to the lowest position of the water inlet section of the second water outlet pipe, as the water level continues to rise, after the water film on the liquid surface breaks, the water flow rate flowing into the water inlet section of the second water outlet pipe is also relatively small, and the water flow rate flowing out of the second water outlet pipe is also relatively small. The water flow flowing out of the second water outlet pipe merges with the water flow flowing out of the first water outlet pipe into a water column, and the water flow of the water column does not change much. As the liquid level continues to rise, the water flow rate flowing into the water inlet section of the second water outlet pipe continues to increase, and the water flow flowing out of the second water outlet pipe also continues to increase. The water column formed by the water flow flowing out of the second water outlet pipe and the water flow flowing out of the first water outlet pipe continues to increase, and finally when the water level in the water vapor separation box reaches a stable state, the water flow of the water column remains in a stable state. This arrangement reduces the risk of the water column suddenly thickening in a short period of time when the water outlet starts to discharge a large amount of water, causing part of the water to be thrown around and easily scalding the user, thereby optimizing the user experience.
[0053] Refer to the following Figures 1 to 7 Hereinafter, the utility model will be introduced. Figure 1 It is a structural schematic diagram of a water vapor separation nozzle of the first embodiment of the utility model; Figure 2 yes Figure 1 A magnified view of the part A in the middle; Figure 3It is a structural schematic diagram of the water vapor separation nozzle of the first embodiment of the utility model without the upper half shell; Figure 4 It is a top view of the water vapor separation nozzle of the first embodiment of the utility model; Figure 5 is along Figure 4 Sectional view of mid-plane BB; Figure 6 The water vapor separation nozzle edge of the second embodiment of the utility model Figure 4 Sectional view of mid-plane BB; Figure 7 The water vapor separation nozzle edge of the third embodiment of the utility model Figure 4 Cross-sectional view of mid-plane BB.
[0054] In the first embodiment of the present invention, Figures 1 to 5 Shown and referenced Figure 5 In the orientation shown, the water vapor separation spout of the drinking water equipment includes a housing 1, which includes an upper half shell 11 and a lower half shell 12. The upper half shell 11 and the lower half shell 12 are buckled together to form the housing 1, and a water vapor separation chamber 13 is formed between the upper half shell 11 and the lower half shell 12. The water vapor separation chamber 13 includes a cavity upper part 131 located in the upper half shell 11 and a cavity lower part 132 located in the lower half shell 12. The top inner wall of the upper half shell 11 is provided with a downwardly extending partition 111, and the partition 111 separates the cavity upper part 131 into a left part and a right part.
[0055] The bottom of the lower half shell 12 is penetrated from bottom to top at a position near the right side, and the upper end of the water inlet pipe 121 extends into the right side portion of the upper part 131 of the cavity, and the lower end of the water inlet pipe 121 forms the water inlet of the water vapor separation nozzle. The bottom of the lower half shell 12 is penetrated from bottom to top at a position near the left side of the water inlet pipe 121, and the upper end of the exhaust pipe 122 extends into the left side portion of the upper part 131 of the cavity, and the lower end of the exhaust pipe 122 forms the exhaust of the water vapor separation nozzle. The bottom of the lower half shell 12 is penetrated from bottom to top at a position near the left side of the exhaust pipe 122, and the first water outlet pipe 21, two second water outlet pipes 22 and one third water outlet pipe 23 are penetrated, and the two second water outlet pipes 22 and one third water outlet pipe 23 are arranged around the first water outlet pipe 21. Among them, a part of the pipe wall of the second water outlet pipe 22 and the third water outlet pipe 23 is formed by a part of the lower half shell 12, and the vertical channels of the second water outlet pipe 22 and the third water outlet pipe 23 include a first equal diameter section, a necking section and a second equal diameter section connected in sequence from top to bottom. The water inlet sections of the first water outlet pipe 21, the second water outlet pipe 22 and the third water outlet pipe 23 are all inserted into the lower cavity 132 of the water vapor separation cavity 13. The vertical channels of the first water outlet pipe 21 and the third water outlet pipe 23 pass through the upper end surface along the axis to form an opening, and the upper end surface is an entire horizontal plane. The vertical channel of the second water outlet pipe 22 passes through the upper end surface along the axis, and the upper end surface includes an inclined plane 221 and a horizontal plane 222 connected to each other. The height of the inclined plane 221 increases continuously from the side away from the horizontal plane 222 to the side close to the horizontal plane 222 at different positions, so that the effective flow area of the water inlet section of the second water outlet pipe 22 gradually increases with the increase of height. The upper ends of the two second water outlet pipes 22 have the same height and the lowest point of the inclined plane 221 of the second water outlet pipe 22 (i.e., the lower end of the second water outlet pipe 22) is higher than the upper end of the first water outlet pipe 21 (i.e., the upper end of the water outlet end of the first water outlet pipe 21), and the upper end of the third water outlet pipe 23 is higher than the upper end of the second water outlet pipe 22.
[0056] The bottom of the lower half shell 12 is also provided with a confluence pipe 3, which includes a first pipe section 31 and a second pipe section 32 that are detachably connected to each other, and the first pipe section 31 is integrally formed with the lower half shell 12. The confluence pipe 3 is sleeved on the outside of the first water outlet pipe 21, and a confluence channel is formed between the confluence pipe 3 and the first water outlet pipe 21. The lower ends of the second water outlet pipe 22 and the third water outlet pipe 23 are connected to the upper end of the confluence channel. The inner wall of the second pipe section 32 is connected to a necking pipe 321 extending from top to bottom near the lower end, and an outlet of the confluence channel is formed between the necking pipe 321 and the first water outlet pipe 21. A semi-cylindrical baffle 211 extends downward from the lower end of the first water outlet pipe 21 on the side away from the water inlet pipe 121.
[0057] In the case where a large water flow flows out of the water vapor separation nozzle, within a period of time after the hot water mixed with high-temperature water vapor begins to enter the water vapor separation chamber 13, a part of the separated hot water flows out from the first water outlet pipe 21, and the water level in the water vapor separation chamber 13 continues to rise. When the water level rises to the lower end of the water inlet section of the second water outlet pipe 22 (the lowest position of the inclined plane 221), as the water level continues to rise, after the water film on the liquid surface breaks, the water flowing into the second water outlet pipe 22 is smaller due to the smaller effective flow area at the current liquid level height. The water flow rate in the water inlet section of the second water outlet pipe 22 is also relatively small, and the water flow rate flowing out of the second water outlet pipe 22 is also relatively small. The water flow flowing out of the second water outlet pipe 22 merges with the water flow flowing out of the first water outlet pipe 21 to form a water column, and the water flow of the water column does not change much. As the liquid level continues to rise, the water flow rate flowing into the water inlet section of the second water outlet pipe 22 continues to increase, and the water flow flowing out of the second water outlet pipe 22 also continues to increase. The water column formed by the water flow flowing out of the second water outlet pipe 22 and the water flow flowing out of the first water outlet pipe 21 continues to increase. When the water level in the water vapor separation chamber 13 is stabilized at a position between the upper end of the second water outlet pipe 22 and the upper end of the third water outlet pipe 23, the water flow of the water column is maintained in a stable state. If the water level in the water vapor separation chamber 13 continues to rise after being higher than the upper end of the second water outlet pipe 22 and eventually maintains a position higher than the upper end of the third water outlet pipe 23, during this process, when the water level rises to the upper end of the third water outlet pipe 23, the water flow out of the third water outlet pipe 23 merges with the water flow formed by the first water outlet pipe 21 and the second water outlet pipe 22, and the water column continues to thicken, but the water flow of the third water outlet pipe 23 is much smaller than the water flow formed by the first water outlet pipe 21 and the second water outlet pipe 22. Therefore, when the water flow of the third water outlet pipe 23 merges into the water flow formed by the first water outlet pipe 21 and the second water outlet pipe 22, the water column will not suddenly increase a lot, and the risk of some water droplets being thrown out is very small. Finally, when the water level in the water vapor separation box reaches a stable state, the water flow of the water column remains in a stable state.
[0058] This arrangement reduces the risk of the water column suddenly thickening in a short period of time when the water outlet starts to discharge a large amount of water, causing part of the water to be thrown around and easily scalding the user, thereby optimizing the user experience.
[0059] Since the lower end of the first water outlet pipe 21 has a semi-cylindrical baffle 211 extending downward on the side away from the water inlet pipe 121, when only the first water outlet pipe 21 is discharging water, the water flow flowing out of the lower end of the first water outlet pipe 21 always has a good water shape, and part of the water will no longer be thrown out.
[0060] Since the vertical channels of the second water outlet pipe 22 and the third water outlet pipe 23 are both configured to include a first equal-diameter section, a necked section, and a second equal-diameter section that are sequentially connected from top to bottom, when the water flow entering the second water outlet pipe 22 and the third water outlet pipe 23 is small, the water flows flowing out of the second water outlet pipe 22 and the third water outlet pipe 23 have a good water shape, so that the water flows flowing out of the second water outlet pipe 22 and the third water outlet pipe 23 can stably merge with the water flow flowing out of the first water outlet pipe 21, avoiding the occurrence of water droplets splashing caused by the impact force of the intersection of the water flows.
[0061] By setting the confluence pipe 3, the water flows out of the two second water outlet pipes 22 are first merged with the water flow out of the third water outlet pipe 23 and then merged with the water flow out of the first water outlet pipe 21, which is more conducive to the merging of the water flow out of the second water outlet pipe 22 and the water flow out of the third water outlet pipe 23 with the water flow out of the first water outlet pipe 21, optimizes the water type of the outlet water column, and more effectively reduces the risk of water droplets splashing.
[0062] By setting the necked pipe 321, when the flow rate of water flowing into the second water outlet pipe 22 and the third water outlet pipe 23 is small, the outlet water type of the confluent water flow of the second water outlet pipe 22 and the third water outlet pipe 23 can be better guaranteed, which is beneficial for the confluent water flow of the second water outlet pipe 22 and the third water outlet pipe 23 to merge with the water flow out of the first water outlet pipe 21, further reducing the risk of water droplets splashing.
[0063] It should be noted that the inner wall of the second pipe section 32 of the confluence pipe 3 is connected to a necked pipe 321 extending from top to bottom near the lower end, and the outlet of the confluence channel is formed between the necked pipe 321 and the first outlet pipe 21. This is only a specific setting method, which can be adjusted in actual applications, such as the lower end of the second pipe section 32 of the confluence pipe 3 is connected to a necked pipe extending from top to bottom, and the outlet of the confluence channel is formed between the lower end of the necked pipe and the first outlet pipe. In addition, the confluence pipe 3 includes a first pipe section 31 and a second pipe section 32 that are detachably connected to each other, and the first pipe section 31 is integrally formed with the lower half shell 12. This is also a specific setting method, which can be adjusted in actual applications, such as the confluence pipe 3 includes only one pipe section, which can be integrally formed with the lower half shell 12, or can be separately formed and connected to the lower half shell 12. In addition, the number of the second water outlet pipes 22 is two, which is only a specific setting mode, and can be adjusted in actual application, such as the number of the second water outlet pipes 22 is one, three or more. The height of the upper ends of the two second water outlet pipes 22 is the same, which is only a specific setting mode, and can be adjusted in actual application. For example, preferably, the two second water outlet pipes 22 are set to have different upper end heights, so that the heights of the water inlet sections of the two second water outlet pipes 22 are different, which can more effectively lengthen the time for the mixed water column to reach the thickest state from the thinnest state, thereby more effectively reducing the risk of the water column suddenly becoming thicker and part of the water being thrown out to the surroundings and easily scalding the user. In addition, the water inlet pipe 121 and the exhaust pipe 122 are inserted into the water vapor separation chamber 13 from the bottom of the lower half shell 12, which is also a specific setting mode, and can be adjusted in actual application, such as the exhaust pipe can be inserted into the water vapor separation chamber 13 from the top of the upper half shell 11, and the water inlet pipe can be inserted into the water vapor separation chamber 13 from the side of the upper half shell 11. The vertical channel of the second water outlet pipe 22 passes through the upper end surface along the axis, and the upper end surface includes an inclined plane 221 and a horizontal plane 222 connected to each other. The height of the inclined plane 221 increases continuously from the side away from the horizontal plane 222 to different positions on the side close to the horizontal plane 222, so that the effective flow area of the water inlet section of the second water outlet pipe 22 gradually increases with the increase of height. This is also a specific setting method, which can be adjusted in practical applications. For example, the vertical channel of the second water outlet pipe 22 passes through the upper end surface along the axis, and the upper end surface is sequentially distributed with a first part and a second part from the first side to the second side, the second part is a plane, and the first part is an arc surface with a continuously increasing height from different positions on the side away from the second part to the side close to the second part, or a step surface with an intermittent increase; or the vertical channel of the second water outlet pipe 22 passes through the upper end surface along the axis, and the upper end surface is an inclined plane with a gradually increasing height from different positions on the first side to the second side.
[0064] In the second embodiment of the present invention, Figure 6As shown, different from the first embodiment, the upper end surface of the second water outlet pipe 22 is a whole horizontal plane, and the pipe wall of the water inlet section of each second water outlet pipe 22 is provided with four through holes 223 penetrating the pipe wall on one side thereof, and the four through holes 223 are distributed from bottom to top along the axis of the second water outlet pipe 22 in sequence, and the apertures increase in sequence. The sum of the cross-sectional areas of the four through holes 223 is not greater than the minimum cross-sectional area of the second water outlet pipe 22. In this way, the effective flow area of the water inlet section of the second water outlet pipe 22 increases with the increase of the height.
[0065] In the third embodiment of the present utility model, Figure 7 As shown, different from the first embodiment, the upper end surface of the second water outlet pipe 22 is an entire horizontal plane, and a long strip opening 224 is provided on the side wall of the water inlet section of each second water outlet pipe 22, and the cross-sectional shape of the opening 224 in the vertical plane is roughly an inverted triangle.
[0066] In this way, the effective flow area of the water inlet section of the second water outlet pipe 22 gradually increases with the increase of height. When in use, as the water level in the water vapor separation chamber gradually rises, the water flow into the second water outlet pipe 22 will gradually increase with the increase of the water level, so that the water flow out of the second water outlet pipe 22 gradually increases, and then the water column formed by the water flow out of the second water outlet pipe 22 and the water flow out of the first water outlet pipe 21 gradually becomes thicker, which more effectively reduces the risk of the water column suddenly becoming thicker and part of the water being thrown out to the surroundings, which may easily scald the user.
[0067] It should be noted that the opening 224 is not limited to being set to have a cross-sectional shape in the vertical plane that is roughly an inverted triangle. Openings of other shapes with the length direction along the vertical direction and the width gradually increasing from bottom to top are also acceptable, such as an opening with a cross-sectional shape in the vertical plane that is roughly an inverted trapezoid.
[0068] Based on the above embodiments, preferably, the neck tube 321 is made of an elastic material (such as rubber, silicone, etc.).
[0069] Through such an arrangement, when the water flow flowing into the confluence channel is large, the necking tube 321 can undergo elastic deformation as the water flow rate changes, and adaptively adjust the flow cross-sectional area of the confluence channel, which can not only ensure the water shape of the water flow flowing out of the confluence channel, but also reduce the restriction of the size of the necking tube 321 on the water flow rate, reduce the impact force of the confluence water flow merging into the water flow out of the first water outlet pipe 21, and reduce the risk of water droplets splashing.
[0070] In another embodiment, different from the second embodiment, the water inlet sections of the two second water outlet pipes 22 are respectively located in two non-overlapping height ranges, that is, the height of the lower end of the water inlet section of one second water outlet pipe 22 is higher than the height of the upper end of the water inlet section of the other second water outlet pipe 22. The water inlet section of each second water outlet pipe 22 is provided with four through holes 223 penetrating through one side of the pipe wall, and the four through holes 223 are sequentially distributed from bottom to top along the axis of the second water outlet pipe 22 and the apertures increase sequentially.
[0071] In another embodiment, different from the above embodiments, the third water outlet pipe 23 is not provided.
[0072] In another embodiment, different from the above embodiments, the necking tube 321 is not provided.
[0073] In another embodiment, different from the above embodiments, the necking tube 321 and the confluence tube 3 are not provided.
[0074] In addition, the utility model also provides a drinking water device, which includes the water vapor separation nozzle of any one of the above embodiments. It should be noted that the drinking water device can be a drinking water machine with a quick heating function, a water purifier and heat integrated machine, or other suitable drinking water devices.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
