Technical Field

[0001] This utility model relates to the technical field of water purification equipment, specifically a water vapor separation mechanism and pipeline machine. Background Technology

[0002] A water dispenser is an instant hot water device connected to the back end of a water purification system, primarily used in homes, offices, and commercial settings. It connects to a pre-treated water source via an internal piping system and utilizes instant heating technology to quickly provide a variety of water temperatures, including room temperature, warm water, and hot water, thus meeting diverse user needs such as brewing tea, making coffee, and direct drinking.

[0003] Existing water dispensers typically have a water vapor separator to separate steam and liquid water in the hot water, preventing splashing and air blockage and ensuring stable water output. However, after the user stops taking water, the residual water in the water vapor separator still takes a long time to completely drain, causing the outlet to drip continuously or slowly release a small amount of hot water, which seriously affects the user experience.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] The existing water dispensers mentioned above typically have a water-vapor separator to separate steam and liquid water in the hot water. However, after the user stops drawing water, the residual water in the water-vapor separator takes a long time to completely drain, resulting in continuous dripping or a slow flow of a small amount of hot water from the outlet, which seriously affects the user experience. The technical solution adopted by this utility model to solve this problem is as follows: A water vapor separation mechanism includes a separation box body, a water vapor separation chamber provided inside the separation box body, an inlet, an outlet, a water outlet channel located between the inlet and the outlet, and an exhaust channel separated from the water outlet channel. The flow cross-section of the water outlet channel gradually decreases from the inlet to the outlet.

[0006] Furthermore, the horizontal plane where the water inlet is located is higher than the horizontal plane where the water outlet is located, and the water outlet channel is inclined in the vertical direction.

[0007] Furthermore, the water vapor separation chamber is provided with a partition support, and the exhaust channel is provided with an exhaust port communicating with the water vapor separation chamber. The exhaust port and the water outlet are distributed along the height direction of the partition support, and the exhaust port is located above the water outlet.

[0008] Furthermore, the exhaust channel includes a first exhaust channel and a second exhaust channel located on both sides of the water outlet channel, and the partition bracket includes a first partition plate arranged in a horizontal direction and a second partition plate arranged at an inclination relative to the first partition plate. The water vapor separation chamber is divided by the first partition plate and the second partition plate to form the first exhaust channel, the water outlet channel and the second exhaust channel.

[0009] Furthermore, a flow guide connecting plate communicating with the water outlet channel is provided between the first partition plate and the second partition plate. The water outlet includes a first water outlet. The opening of the flow guide connecting plate is arranged facing the water outlet channel, and the first water outlet is opened on the inner side wall of the flow guide connecting plate.

[0010] Furthermore, the water outlet includes a second water outlet and a third water outlet. The height of the flow guiding connecting plate in the vertical direction is lower than the height of the first partition plate and the second partition plate, respectively. The first partition plate, the second partition plate and the flow guiding connecting plate enclose a buffer flow stabilization zone. The second water outlet is located between the outer walls of the first partition plate and the flow guiding connecting plate, and the third water outlet is located between the outer walls of the second partition plate and the flow guiding connecting plate.

[0011] Furthermore, the exhaust port includes a first exhaust port corresponding to the first exhaust channel and a second exhaust port corresponding to the second exhaust channel. The separation box body includes a separation box cover and a separation box body. The separation box cover and the separation box body are connected to each other to enclose and form the water vapor separation chamber. A first gap is provided between the top of the first partition plate and the inner sidewall of the separation box cover, and a second gap is provided between the top of the second partition plate and the inner sidewall of the separation box cover. The first exhaust port communicates with the water vapor separation chamber through the first gap, and the second exhaust port communicates with the water vapor separation chamber through the second gap.

[0012] Furthermore, both the second and third water outlets are arranged in an arc shape, and the second and third water outlets are symmetrically arranged on both sides of the first water outlet.

[0013] Furthermore, the length of the water vapor separation chamber in the horizontal direction is L1, and the height of the water vapor separation chamber in the vertical direction is H1, where L1 > H1.

[0014] This utility model also provides a pipeline machine, including a body, the body including a water vapor separation mechanism as described above.

[0015] The beneficial effects of this utility model are as follows: This invention features a water outlet channel located between the inlet and outlet, with the cross-section of the channel gradually decreasing from the inlet to the outlet. According to fluid mechanics principles, under the premise of constant flow rate, a smaller cross-section results in a faster flow velocity. This significantly increases the speed of water flowing through the outlet channel, allowing residual water to be quickly discharged after water supply is stopped, greatly shortening dripping time. This effectively solves the problem that existing water dispensers typically have a water vapor separator to separate steam and liquid water in hot water. However, after the user stops drawing water, the residual water in the water vapor separator takes a long time to completely drain, resulting in continuous dripping or a slow flow of a small amount of hot water from the outlet, severely affecting the user experience.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1 to 10The water vapor separation mechanism shown includes a separation box body 1, a water vapor separation chamber 2 inside the separation box body 1, an inlet 3, an outlet 4, a water outlet channel 5 located between the inlet 3 and the outlet 4, and an exhaust channel 6 separated from the water outlet channel 5. The flow cross section of the water outlet channel 5 gradually decreases from the inlet 3 toward the outlet 4. This invention features a water outlet channel located between the inlet and outlet, with the cross-section of the channel gradually decreasing from the inlet to the outlet. According to fluid mechanics principles, under the premise of constant flow rate, a smaller cross-section results in a faster flow velocity. This significantly increases the speed of water flowing through the outlet channel, allowing residual water to be quickly discharged after water supply is stopped, greatly shortening dripping time. This effectively solves the problem that existing water dispensers typically have a water vapor separator to separate steam and liquid water in hot water. However, after the user stops drawing water, the residual water in the water vapor separator takes a long time to completely drain, resulting in continuous dripping or a slow flow of a small amount of hot water from the outlet, severely affecting the user experience.

[0020] Furthermore, the flow cross-section of the water outlet channel 5 gradually decreases. According to the principle of fluid continuity (Q=A*V), where Q is the flow rate, A is the flow cross-section, and V is the flow velocity, when the flow rate Q is constant, the decrease in the flow cross-section A will lead to an increase in the flow velocity V. At the moment when the user stops taking water, the residual water in the water vapor separation chamber 2 will have a significantly faster speed when it passes through the gradually narrowing water outlet channel 5, so that it can completely pass through and leave the water outlet 4 in a shorter time, which greatly reduces the residence time of residual water in the water outlet channel 5.

[0021] Specifically, the flow cross section of the outlet channel 5 refers to the cross-sectional area perpendicular to the flow direction when water flows through the outlet channel 5. Under constant flow conditions, the shape of the flow cross section can change along the flow path, but it always remains orthogonal to the local flow velocity direction.

[0022] Specifically, after the hot water enters the water vapor separation chamber 2 through the inlet 3, the steam naturally rises due to its lower density and gathers at the top of the water vapor separation chamber 2, while the liquid water sinks due to gravity and flows along the outlet channel 5 to the outlet 4. The steam is discharged to the outside through the exhaust port 8 and the exhaust channel 6, while the liquid water flows out through the outlet 4 at the bottom of the water vapor separation chamber 2, thereby achieving effective gas-liquid separation.

[0023] Optionally, in some embodiments, the water outlet channel 5 is generally in the shape of a conical tube. The end of the water outlet channel 5 near the water inlet 3 is the large-diameter end. Along the water flow direction, the inner diameter of the water outlet channel 5 gradually decreases until the end near the water outlet 4 forms a small-diameter end. The inner diameter is slightly larger than the orifice diameter of the water outlet 4. The cross-section is uniformly and gradually changed through the conical sidewall. The water flow velocity in the water outlet channel 5 increases steadily, which not only realizes the separation of steam and liquid water, but also reduces the water flow retention time.

[0024] Optionally, in some embodiments, the water outlet channel 5 is composed of multiple straight pipe sections with progressively smaller inner diameters. Each straight pipe section is connected by a transition slope and is fixed as a whole in the water vapor separation chamber 2. The first straight pipe section near the water inlet 3 has the largest inner diameter, and the inner diameter of each subsequent straight pipe section is smaller than the previous one. Finally, the inner diameter of the last straight pipe section matches the water outlet 4. The stepped structure achieves a gradual change in cross-section through segmented shrinkage, which is less difficult to process than the conical channel. In addition, the inner walls of each straight pipe section are flat, making it easy to clean.

[0025] Optionally, in some embodiments, the inner wall of the water outlet channel 5 is designed with an arc-shaped curved surface. From the water inlet 3 end to the water outlet 4 end, the curved surface gradually shrinks inward, so that the flow cross section of the water outlet channel 5 has a smooth and gradual trend. The radius of curvature of the inner wall curved surface of the water outlet channel 5 gradually decreases from the water inlet 3 end to the water outlet 4 end, ensuring that there is no obvious resistance when the water flows along the curved surface, and avoiding the generation of eddies due to abrupt changes in cross section.

[0026] Furthermore, as a preferred embodiment of this utility model, rather than a limitation, the water outlet channel 5 is divided into two sections within the water vapor separation chamber 2. The two sections are seamlessly connected along the water flow direction, and the flow cross-section gradually decreases from the inlet 3 to the outlet 4. The first part near the inlet 3 is a rectangular cross-section, which helps ensure that hot water containing steam can flow in smoothly. At the same time, the rectangular cross-section can provide a larger initial flow space, reducing the impact when the water flows in. The second part near the outlet 4 is a right-angled triangular cross-section. The sidewall where the right angle is located is seamlessly connected to the sidewall of the first rectangular cross-section, and the hypotenuse is inclined towards the inside of the channel, so that the area of ​​the triangular cross-section gradually decreases from the end connected to the rectangular section to the end of the outlet 4. Finally, the smallest end of the triangular cross-section matches the diameter of the outlet 4. Through the combination of rectangular and triangular cross-sections, not only is the requirement for a gradual change in the flow cross-section achieved, but the space utilization rate of the water vapor separation chamber 2 is also improved.

[0027] like Figures 1 to 10 The horizontal plane where the water inlet 3 is located is higher than the horizontal plane where the water outlet 4 is located, and the water outlet channel 5 is inclined in the vertical direction; Furthermore, the inlet 3 is higher than the outlet 4, causing the outlet channel 5 to slope downwards in the vertical direction. When the water flows through, it can accelerate the flow with the help of gravity, which is beneficial to increase the flow rate. In particular, it can discharge the residual water more quickly after the water is stopped, effectively shortening the dripping time.

[0028] Furthermore, the inclined structure makes it less likely for water to stagnate in the water outlet channel 5, avoiding the formation of "dead water zones" or localized liquid accumulation. Combined with the tapered cross section, it can further enhance the drainage effect, thereby achieving a more thorough and rapid water shut-off, which is conducive to improving the user experience.

[0029] Furthermore, the downward-sloping water outlet channel 5 facilitates the stable flow of liquid water to the water outlet 4, while the steam, due to its lower density, naturally rises to the top of the water vapor separation chamber 2. The paths of steam and liquid water are clearly separated, which helps to reduce the phenomenon of gas being ejected with the water flow and improves the water vapor separation effect.

[0030] like Figures 1 to 10 The water vapor separation chamber 2 shown is provided with a partition bracket 7, and the exhaust channel 6 is provided with an exhaust port 8 communicating with the water vapor separation chamber 2. The exhaust port 8 and the water outlet 4 are distributed along the height direction of the partition bracket 7, and the exhaust port 8 is located above the water outlet 4. Furthermore, the exhaust port 8 is located above the water outlet 4. Combined with the separating function of the partition bracket 7, a "gas above and water below" spatial layout is formed. After the high-temperature hot water enters the water vapor separation chamber 2, the steam naturally rises to the top of the water vapor separation chamber 2 due to its low density and is discharged through the exhaust port 8; the liquid water sinks to the bottom due to gravity and flows out from the water outlet 4, which is conducive to the orderly separation of gas and liquid.

[0031] Furthermore, if the exhaust port 8 is positioned too low or flush with the water outlet 4, steam may directly mix into the water flow, easily causing a "bursting" phenomenon. Placing the exhaust port 8 at the top can effectively block the gas-liquid short-circuit path, which helps to ensure a stable and gentle water flow and effectively improves the user experience.

[0032] Furthermore, the separator 7 acts as a physical barrier, guiding the water flow along a predetermined path to avoid turbulent disturbances. At the same time, it provides independent outlet channels for the gas and liquid phases, reducing mutual interference and improving the stability of the system.

[0033] like Figures 1 to 10 The exhaust channel 6 shown includes a first exhaust channel 61 and a second exhaust channel 62 located on both sides of the water outlet channel 5. The partition bracket 7 includes a first partition plate 71 arranged in the horizontal direction and a second partition plate 72 arranged at an inclination relative to the first partition plate 71. The water vapor separation chamber 2 is divided by the first partition plate 71 and the second partition plate 72 to form the first exhaust channel 61, the water outlet channel 5 and the second exhaust channel 62. Furthermore, the first exhaust channel 61 and the second exhaust channel 62 are located on both sides of the water outlet channel 5, forming a symmetrical or asymmetrical double-sided exhaust structure, which can simultaneously exhaust the steam floating from both sides of the water flow, which is conducive to expanding the exhaust area, helping to shorten the gas residence time, and effectively improving the water vapor separation efficiency.

[0034] Furthermore, through the coordinated separation of the first partition plate 71 and the second partition plate 72, the water vapor separation chamber 2 is divided into three independent flow channels, namely the first exhaust channel 61, the middle water outlet channel 5, and the second exhaust channel 62. This facilitates the realization of "one chamber for three uses", making the overall structure of the device compact and improving space utilization.

[0035] Furthermore, the second partition plate 72 is inclined relative to the first partition plate 71. The inclined surface of the second partition plate 72 can serve as a guide surface to guide the water flow smoothly through the water outlet channel 5, which helps to reduce water flow impact and eddy generation, and avoids the situation where gas and liquid remixing occurs due to violent disturbance.

[0036] like Figures 1 to 10 A flow guide plate 51 communicating with the water outlet channel 5 is provided between the first partition plate 71 and the second partition plate 72 shown. The water outlet 4 includes a first water outlet 41. The opening of the flow guide plate 51 is arranged facing the water outlet channel 5, and the first water outlet 41 is opened on the inner side wall of the flow guide plate 51. Furthermore, the flow guiding plate 51 connects the first partition plate 71 and the second partition plate 72, and the opening of the flow guiding plate 51 faces the water outlet channel 5, which is conducive to forming a continuous and smooth flow guiding path, so that the water flow entering the water outlet channel 5 can smoothly transition, avoiding the occurrence of eddies, impacts or gas-liquid remixing due to structural abrupt changes, which is conducive to improving the stability of water outlet.

[0037] Furthermore, the flow guiding connecting plate 51 serves as a transition structure connecting the first partition plate 71 and the second partition plate 72, which helps to enhance the overall rigidity and stability of the partition bracket 7 and prevent deformation caused by water flow pressure or vibration.

[0038] Specifically, the flow guide plate 51 connects the first partition plate 71 and the second partition plate 72, providing additional support for the first partition plate 71 and the second partition plate 72 and enhancing the overall structural strength of the partition bracket 7. It can also utilize the gap between the first partition plate 71 and the second partition plate 72 to construct the water outlet channel 5 without occupying the independent space of the water vapor separation chamber 2. Furthermore, the first water outlet 41 is opened on the inner side wall of the flow guide plate 51, which can form a compact layout of "water outlet in the middle and exhaust on both sides" with the first exhaust channel 61 and the second exhaust channel 62 on both sides.

[0039] like Figures 1 to 10The water outlet 4 shown includes a second water outlet 42 and a third water outlet 43. The height of the flow guiding connecting plate 51 in the vertical direction is lower than the height of the first partition plate 71 and the second partition plate 72, respectively. The first partition plate 71, the second partition plate 72 and the flow guiding connecting plate 51 enclose a buffer flow stabilization zone 511. The second water outlet 42 is located between the outer wall of the first partition plate 71 and the outer wall of the flow guiding connecting plate 51, and the third water outlet 43 is located between the outer wall of the second partition plate 72 and the outer wall of the flow guiding connecting plate 51. Furthermore, most of the water flow is discharged through the first outlet 41, which helps to ensure the stability of the main drainage path during daily water intake, thereby meeting the user's regular water intake needs. The buffer flow stabilization zone 511 can receive a small amount of residual water that is not discharged in time from the first outlet 41. This residual water can be quickly discharged through the second outlet 42 and the third outlet 43 on both sides, avoiding the residual water from stagnating in the water vapor separation chamber 2 and greatly shortening the dripping time after water intake stops.

[0040] Furthermore, during the buffering process, the buffer stabilization zone 511 can further separate the trace amounts of residual steam in the water flow. Because of their low density, these steam particles will flow upwards to the exhaust ports on both sides and be discharged through the exhaust channel 6. Meanwhile, most of the water flow will be discharged from the first outlet 41 along the stabilization path, and a small amount of residual water will be discharged from the second outlet 42 and the third outlet 43. This prevents steam from mixing with the water flow and overflowing from each outlet, ensuring that there is no steam interference when the water is discharged.

[0041] Furthermore, the flow guide plate 51 forms a buffer flow stabilization zone 511 by enclosing the height difference between the first partition plate 71 and the second partition plate 72, respectively, without the need to increase the volume of the water vapor separation chamber 2. The second outlet 42 and the third outlet 43 are set by utilizing the gap between the first partition plate 71 and the second partition plate 72 and the flow guide plate 51, respectively, without the need to open up separate installation space.

[0042] like Figures 1 to 10 The exhaust port 8 shown includes a first exhaust port 81 corresponding to the first exhaust channel 61 and a second exhaust port 82 corresponding to the second exhaust channel 62. The separation box body 1 includes a separation box cover 11 and a separation box body 12. The separation box cover 11 and the separation box body 12 are connected to each other to form the water vapor separation chamber 2. A first gap is provided between the top of the first partition plate 71 and the inner side wall of the separation box cover 11. A second gap is provided between the top of the second partition plate 72 and the inner side wall of the separation box cover 11. The first exhaust port 81 communicates with the water vapor separation chamber 2 through the first gap, and the second exhaust port 82 communicates with the water vapor separation chamber 2 through the second gap. Furthermore, the first exhaust port 81 corresponds to the first exhaust channel 61, and the second exhaust port 82 corresponds to the second exhaust channel 62, forming a dual-path independent exhaust structure. This structure can simultaneously exhaust the steam distributed on both sides of the water outlet channel 5, which is beneficial for expanding the exhaust area, shortening the gas residence time, effectively improving the water vapor separation efficiency, and avoiding airflow congestion.

[0043] Furthermore, by pre-reserving a first gap and a second gap between the top of the first partition plate 71 and the second partition plate 72 and the inner sidewall of the separation box cover 11, a gas flow channel is naturally formed. There is no need to open additional air guide holes or install air guide pipes on the separation box cover 11, the first partition plate 71 or the second partition plate 72. The structure is relatively simple, which helps to reduce the complexity of the mold and the manufacturing cost.

[0044] Furthermore, the separation box cover 11 and the separation box body 12 can be connected by means of snaps, screws or ultrasonic welding, forming a first gap and a second gap during assembly, without the need for additional adjustment or positioning, which is beneficial for automated production.

[0045] like Figures 1 to 10 The second outlet 42 and the third outlet 43 shown are both arc-shaped, and the second outlet 42 and the third outlet 43 are symmetrically arranged on both sides of the first outlet 41. Furthermore, both the second outlet 42 and the third outlet 43 are arc-shaped with smooth edges and no sharp corners, which can effectively reduce the local resistance when water flows through, avoid the occurrence of eddies, and allow residual water to be discharged more smoothly from the lateral gap, thus effectively improving drainage efficiency.

[0046] Furthermore, the symmetrically distributed second outlet 42 and third outlet 43 help to expand the drainage area. Combined with the guiding effect of the arc structure, they can accelerate the synchronous discharge of residual water in the buffer flow stabilization zone 511, which helps to significantly shorten the dripping time after water stoppage, thereby achieving a faster water stop response and effectively improving the user experience.

[0047] Furthermore, the arc-shaped second outlet 42 and third outlet 43 have no sharp corners. Compared with right angle or acute angle structures, this can prevent the water flow from generating local eddies or stagnating due to sharp corners when it flows out, allowing the residual water in the buffer flow stabilization zone 511 to be discharged more smoothly through the second outlet 42 and third outlet 43.

[0048] like Figures 1 to 10 The water vapor separation chamber 2 shown has a horizontal length of L1 and a vertical height of H1, where L1 > H1. Furthermore, after the water enters from the inlet 3, it needs to flow horizontally through the outlet channel 5 or the buffer flow stabilization zone 511. The setting of L1>H1 makes the horizontal flow path of the water in the water vapor separation chamber 2 longer. The longer path allows the water to have more time to complete the separation of steam and liquid water.

[0049] Furthermore, the setting of L1>H1 helps to ensure that the water flow is subjected to uniform force during the discharge process, reduces the structural stress concentration caused by the concentrated water flow, and helps to enhance the structural stability of the entire water vapor separation chamber 2; secondly, the setting of L1>H1 can reduce the pressure concentration caused by the concentrated water flow, which helps to reduce the risk of structural damage caused by excessive pressure.

[0050] like Figures 1 to 10 The pipeline machine shown includes a body 9, which includes a water vapor separation mechanism as described above. Specifically, by setting the separation box body 1 in the body 9, the steam and liquid water in the hot water can be effectively separated, preventing splashing, flow interruption or water-steam mixing when the water is discharged; secondly, the gradually narrowing and inclined water outlet channel 5 helps to improve the water flow speed and residual water drainage efficiency, and achieves rapid water stop after water is stopped, avoiding dripping problems; finally, the dual exhaust channels 6 and the separator bracket 7 work together to form an efficient separation path of "air above and water below", which helps to improve the stability of water output and drinking safety.

[0051] The implementation method of Example 1 is as follows: A water vapor separation mechanism includes a separation box body 1, a water vapor separation chamber 2 inside the separation box body 1, an inlet 3, an outlet 4 inside the water vapor separation chamber 2, an outlet channel 5 located between the inlet 3 and the outlet 4, and an exhaust channel 6 separated from the outlet channel 5. The flow cross section of the outlet channel 5 gradually decreases from the inlet 3 toward the outlet 4.

[0052] This invention features a water outlet channel located between the inlet and outlet, with the cross-section of the channel gradually decreasing from the inlet to the outlet. According to fluid mechanics principles, under the premise of constant flow rate, a smaller cross-section results in a faster flow velocity. This significantly increases the speed of water flowing through the outlet channel, allowing residual water to be quickly discharged after water supply is stopped, greatly shortening dripping time. This effectively solves the problem that existing water dispensers typically have a water vapor separator to separate steam and liquid water in hot water. However, after the user stops drawing water, the residual water in the water vapor separator takes a long time to completely drain, resulting in continuous dripping or a slow flow of a small amount of hot water from the outlet, severely affecting the user experience.

[0053] The implementation method of Example 2 is as follows: Based on Example 1, Example 2 also has the following implementation method: the horizontal plane where the water inlet 3 is located is higher than the horizontal plane where the water outlet 4 is located, and the water outlet channel 5 is inclined in the vertical direction.

[0056] The implementation method of Example 5 is as follows: Based on Example 4, Example 5 also has the following implementation method: A flow guiding connecting plate 51 communicating with the water outlet channel 5 is provided between the first partition plate 71 and the second partition plate 72.

The opening of the flow guiding connecting plate 51 is set facing the water outlet channel 5, and the first water outlet 41 is opened on the inner side wall of the flow guiding connecting plate 51.

[0057] The implementation method of Example 6 is as follows: Based on Example 5, Example 6 further includes the following implementation: the outlet 4 includes a second outlet 42 and a third outlet 43. The height of the flow guiding connecting plate 51 in the vertical direction is lower than the height of the first partition plate 71 and the second partition plate 72, respectively. The first partition plate 71, the second partition plate 72 and the flow guiding connecting plate 51 enclose a buffer flow stabilization zone 511. The second outlet 42 is located between the outer wall of the first partition plate 71 and the flow guiding connecting plate 51, and the third outlet 43 is located between the outer wall of the second partition plate 72 and the flow guiding connecting plate 51.

[0058] The implementation method of Example 7 is as follows: Based on Example 4, Example 7 further includes the following implementation: the exhaust port 8 includes a first exhaust port 81 corresponding to the first exhaust channel 61 and a second exhaust port 82 corresponding to the second exhaust channel 62. The separation box body 1 includes a separation box cover 11 and a separation box body 12. The separation box cover 11 and the separation box body 12 are connected to each other to form a water vapor separation chamber 2. A first gap is provided between the top of the first partition plate 71 and the inner side wall of the separation box cover 11, and a second gap is provided between the top of the second partition plate 72 and the inner side wall of the separation box cover 11. The first exhaust port 81 communicates with the water vapor separation chamber 2 through the first gap, and the second exhaust port 82 communicates with the water vapor separation chamber 2 through the second gap.

[0059] The implementation method of Example 8 is as follows: Based on Example 6, Example 8 also has the following implementation method: the second water outlet 42 and the third water outlet 43 are both arranged in an arc shape, and the second water outlet 42 and the third water outlet 43 are respectively symmetrically arranged on both sides of the first water outlet 41.

The end of the water outlet channel 5 near the water inlet 3 is the large diameter end. Along the water flow direction, the inner diameter of the water outlet channel 5 gradually decreases, and the end near the water outlet 4 forms a small diameter end. The inner diameter is slightly larger than the orifice diameter of the water outlet 4. The cross-section is uniformly and gradually changed through the conical sidewall. The water flow velocity in the water outlet channel 5 increases steadily, which not only realizes the separation of steam and liquid water, but also reduces the water flow retention time.

[0063] The implementation method of Example Twelve is as follows: The difference between Example 12 and Example 11 is that the water outlet channel 5 is composed of multiple straight pipe sections with progressively smaller inner diameters. Each straight pipe section is connected by a transition slope and is fixed as a whole in the water vapor separation chamber 2. The first straight pipe section near the inlet 3 has the largest inner diameter, and the inner diameter of each subsequent straight pipe section is smaller than the previous one. The inner diameter of the final straight pipe section matches the water outlet 4. The stepped structure achieves a gradual change in cross-section through segmented shrinkage, which is less difficult to process than the conical channel. In addition, the inner walls of each straight pipe section are flat, making it easy to clean.

[0064] The implementation method of Example Thirteen is as follows: The difference between Example 13 and Example 11 is that the inner wall of the water outlet channel 5 is designed with an arc-shaped curved surface. From the water inlet 3 end to the water outlet 4 end, the curved surface gradually shrinks inward, so that the flow cross section of the water outlet channel 5 has a smooth and gradual trend. The radius of curvature of the inner wall curved surface of the water outlet channel 5 gradually decreases from the water inlet 3 end to the water outlet 4 end, ensuring that there is no obvious resistance when the water flows along the curved surface, and avoiding the generation of eddies due to abrupt changes in cross section.

[0065] The implementation method of Example Fourteen is as follows: The difference between Example 14 and Example 11 is that the water outlet channel 5 is divided into two sections within the water vapor separation chamber 2. The two sections are seamlessly connected along the water flow direction, and the flow cross-section gradually decreases from the inlet 3 to the outlet 4. The first part near the inlet 3 is a rectangular cross-section, which helps to ensure that the hot water containing steam can flow in smoothly. At the same time, the rectangular cross-section can provide a larger initial flow space and reduce the impact when the water flows in. The second part near the outlet 4 is a right-angled triangular cross-section. The sidewall where the right angle is located is seamlessly connected to the sidewall of the first rectangular cross-section, and the hypotenuse is inclined towards the inside of the channel, so that the area of ​​the triangular cross-section gradually decreases from the end connected to the rectangular section to the end of the outlet 4. Finally, the smallest end of the triangular cross-section matches the diameter of the outlet 4. By combining the rectangular and triangular cross-sections, not only is the requirement for a gradual change in the flow cross-section achieved, but the space utilization of the water vapor separation chamber 2 is also improved.
