Description

Technical Field

[0001] The utility model relates to the technical field of faucets, and specifically provides a water vapor separation box and a faucet. Background Art

[0002] The instant hot water purifier under the kitchen is a device that combines water purification and rapid heating. Usually, the main unit is installed under the cabinet and the faucet is installed on the cabinet. The instant heating body can be fixed in the main unit or in the faucet. When the instant heating body heats and prepares hot water, a lot of water vapor will be generated. The water vapor and hot water are mixed together and flow out from the water outlet, which is prone to water flow interruption and shaking.

[0003] In order to prevent water vapor from flowing out of the water outlet of the faucet along with the hot water, a water vapor separation box is provided in the improved faucet. The inlet of the water vapor separation box is connected to the outlet of the instant heating body through a pipeline, and the outlet of the water vapor separation box serves as the outlet of the faucet. The hot water mixed with water vapor flowing out of the instant heating heater flows into the water vapor separation box, and the water vapor and hot water are separated in the water vapor separation box. The water vapor is discharged through the exhaust port of the water vapor separation box, and the hot water with water vapor precipitated flows out from the outlet of the water vapor separation box. This reduces the interruption and shaking of the water outflow from the faucet to a certain extent.

[0004] However, in daily use, due to water pressure fluctuations or slight changes in the speed of the water pump in the pipeline, the water outlet flow rate of the water vapor separation box will change to a certain extent. When the water outlet flow rate of the water vapor separation box changes, the water shape is also prone to change, and water droplets are prone to splashing.

[0005] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0010] In the preferred technical solution of the above-mentioned water vapor separation box, a second pipe body extends downward from the bottom plate of the housing. The second pipe body is sleeved outside the first pipe body. A first channel is formed between the second pipe body and the first pipe body. A second channel is further formed in the housing. The first end of the second channel is higher than the upper end of the first pipe body. The upper end of the first channel communicates with the second end of the second channel. The first channel and the second channel constitute the exhaust passage, and the lower end of the first channel forms the exhaust port.

[0011] In the preferred technical solution of the above-mentioned water vapor separation box, a first arc plate, a second arc plate, a first connecting plate and a second connecting plate extend upward from the bottom plate. The first arc plate has the same diameter and is coaxial with the first pipe body. The second arc plate has the same diameter and is coaxial with the second pipe body. Two side edges of the first arc plate are respectively connected to two side edges of the second arc plate through the first connecting plate and the second connecting plate; the first arc plate, the second arc plate, the first connecting plate and the second connecting plate enclose the second channel.

The upper surface of the first annular rib abuts against the lower end surface of the second pipe body. The upper surface of the second annular rib abuts against the lower surface of the first annular rib. The internal thread is screwed together with the external thread.

[0015] In the preferred technical solution of the above-mentioned water-vapor separation box, the water inlet is a quick-connect joint formed on the housing; and / or a buffer plate facing the water inlet is arranged inside the housing.

[0016] In the case of adopting the above technical solution, the water-vapor separation box is used to be installed on a faucet. The water-vapor separation box includes a housing, a water-vapor separation cavity is formed inside the housing, a water inlet and an exhaust port communicating with the water-vapor separation cavity are arranged on the housing, a water outlet communicating with the water-vapor separation cavity is arranged at the bottom of the housing, the water outlet serves as the water outlet of the faucet, and a mesh plate is arranged at the water outlet. The middle area of the upper surface of the mesh plate is recessed downward relative to the edge area.

[0017] Through such a setting, after water vapor and hot water are separated in the water-vapor separation box, the water vapor is discharged through the exhaust port of the water-vapor separation box, and the hot water from which the water vapor is separated flows out through the mesh holes of the mesh plate when flowing out from the water outlet of the water-vapor separation box. Since the middle area of the upper surface of the mesh plate is recessed downward relative to the edge area, the water flow at the water outlet converges towards the middle area of the mesh plate, making the water flow of the water outlet have a good water shape. When the water outlet flow rate changes, the water flow of the water outlet can also maintain a good water shape, reducing the risk of water droplet splashing caused by the change of the water shape when the water outlet flow rate changes, and optimizing the user experience.

[0018] Preferably, the middle area of the lower surface of the mesh plate protrudes downward relative to the edge area, and the thickness of different areas of the mesh plate is the same.

[0019] Through such a setting, under the action of the surface tension of water and the adhesion force between water and the lower surface of the mesh plate, the water is more inclined to converge towards the middle after flowing out from the mesh holes of the mesh plate, which is more conducive to the water flow of the water outlet maintaining a good water shape. In addition, the thickness of different areas of the mesh plate is the same, which facilitates the manufacture of the mesh plate and avoids the occurrence of stress concentration easily caused by uneven thickness in different parts of the mesh plate.

[0020] Preferably, a first pipe body extends downward from the bottom plate of the housing. The upper end of the first pipe body communicates with the water-vapor separation cavity, and the lower end of the first pipe body forms a water outlet; the water-vapor separation box is provided with an exhaust passage. The intake end of the exhaust passage communicates with the water-vapor separation cavity, and the outlet end of the exhaust passage forms an exhaust port. The exhaust port is arranged adjacent to the water outlet.

[0021] Through such a setting, the risk of the high-temperature water vapor flowing towards the surrounding human body and causing scalding to the human body can be reduced, and the safety of use can be improved.

[0022] Preferably, a second tube body extends downward from the bottom plate of the housing. The second tube body is sleeved outside the first tube body, and a first channel is formed between the second tube body and the first tube body. A second channel is also formed inside the housing. The first end of the second channel is higher than the upper end of the first tube body. The upper end of the first channel is communicated with the second end of the second channel. The first channel and the second channel constitute an exhaust channel, and the lower end of the first channel forms an exhaust port.

[0023] Through such a setting, water vapor is discharged from the annular exhaust port surrounding the water outlet, forming an annular air flow sleeved outside the water outlet flow, that is, a protective air layer is formed outside the water outlet water column, which can further reduce the risk of water droplets splashing outward from the water outlet flow.

[0024] Preferably, the edge of the mesh plate is connected to the lower end of the second tube body, and there is a water passing gap between the lower end of the first tube body and the upper surface of the mesh plate.

[0025] Through such a setting, when the water outlet flow is large, a part of the water can spread from the water passing gap to the edge of the mesh plate and flow out through the mesh holes in the edge area of the mesh plate, so as to meet the water outlet demand for a large amount of water.

[0026] Preferably, the water inlet includes a hot water inlet and a normal temperature water inlet.

[0027] Through such a setting, when the faucet needs to discharge normal temperature water, the normal temperature water flows into the water vapor separation box through the normal temperature water inlet and finally flows out from the water outlet of the water vapor separation box. In this way, on the basis of meeting the water outlet demand for normal temperature water, there is no need to separately set a normal temperature water outlet, avoiding the situation of increasing the volume of the faucet due to separately setting a normal temperature water outlet, simplifying the structure of the faucet and reducing the volume of the faucet.

[0028] Preferably, the water inlet includes a quick connector formed on the housing.

[0029] Through such a setting, it is convenient to connect the water inlet to the water inlet pipe.

[0040] First of all, those skilled in the art should understand that the implementation manners described below are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0041] It should be noted that in the description of the utility model, terms indicating directions or positional relationships such as "left" and "right" are based on the directions or positional relationships shown in the drawings. This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] In addition, it should also be noted that in the description of the present utility model, unless otherwise clearly specified and defined, 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. It can be a direct connection or an indirect connection. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0043] Based on the problem that when the water flow rate at the outlet of the water vapor separation box on the faucet mentioned in the background art changes, it is easy to change the water shape and cause water droplets to splash, the present utility model provides a water vapor separation box, which is used to be installed on the faucet. The water vapor separation box includes a housing, a water vapor separation cavity is formed inside the housing, a water inlet and an exhaust port communicated with the water vapor separation cavity are arranged on the housing, a water outlet communicated with the water vapor separation cavity is arranged at the bottom of the housing, the water outlet serves as the water outlet of the faucet, and a mesh plate is arranged at the water outlet, and the middle area of the upper surface of the mesh plate is recessed downward relative to the edge area.

[0044] Through such a setting, after the water vapor and hot water are separated in the water vapor separation box, the water vapor is discharged through the exhaust port of the water vapor separation box, and the hot water from which the water vapor is separated flows out through the meshes of the mesh plate when flowing out from the water outlet of the water vapor separation box. Since the middle area of the upper surface of the mesh plate is recessed downward relative to the edge area, the water flow at the water outlet converges towards the middle area of the mesh plate, making the water flow have a good water shape. When the water flow rate changes, it can also keep the water flow have a good water shape, reducing the risk of water droplet splashing caused by the change of the water shape when the water flow rate changes, and optimizing the user experience.

[0045] The following refers to Figures 1 to 5 for a detailed introduction to the water vapor separation box of the present utility model. Among them, Figure 1 is a schematic structural diagram of the water vapor separation box of an embodiment of the present utility model;

[0046] Figure 2 is a schematic structural diagram of the water vapor separation box of an embodiment of the present utility model in the state of removing the upper cover;

[0047] Figure 3 is a top view of the water vapor separation box of an embodiment of the present utility model; Figure 4 is along Figure 3 the sectional view taken along the A-A plane in Figure 5 is Figure 4 the enlarged view of the partial B in

[0048] The water vapor separation box of the present utility model is used to be installed on the faucet. As Figures 1 to 4 shown, the water vapor separation box includes a housing 1, the housing 1 includes a bottom shell 11 and an upper cover 12, the bottom shell 11 includes a bottom plate 111 and four side plates 112 connected to the periphery of the bottom plate 111, the bottom plate 111 and the side plates 112 are integrally formed, the upper cover 12 is buckled on the upper part of the bottom shell 11, and the upper cover 12 and the bottom shell 11 enclose a water vapor separation cavity 13 inside the housing 1.

[0049] The housing 1 is provided with a water inlet and an exhaust port that communicate with the water-vapor separation chamber 13. The bottom of the housing 1 is provided with a water outlet that communicates with the water-vapor separation chamber 13. The water outlet serves as the water outlet of the faucet, and a mesh plate 5 is arranged at the water outlet. The middle area of the upper surface of the mesh plate 5 is recessed downward relative to the edge area.

[0050] Specifically, as Figures 1 to 4 shown, a hot water inlet joint 21 and a normal temperature water inlet joint 22 are arranged on the left side plate 112. Both the hot water inlet joint 21 and the normal temperature water inlet joint 22 communicate with the water-vapor separation chamber 13 and respectively serve as the hot water inlet for flowing hot water into the water-vapor separation chamber 13 and the normal temperature water inlet for flowing normal temperature water into the water-vapor separation chamber 13. Both the hot water inlet joint 21 and the normal temperature water inlet joint 22 are quick-connect joints.

[0051] As Figure 4 shown, the bottom plate 111 of the housing 1 extends downward to form a first pipe body 31 and a second pipe body 32. The upper end of the first pipe body 31 communicates with the water-vapor separation chamber 13, and the lower end of the first pipe body 31 forms a water outlet. The second pipe body 32 is sleeved outside the first pipe body 31, and a first channel 33 with an annular cross-section is formed between the second pipe body 32 and the first pipe body 31. As Figure 2 and Figure 4 shown, the bottom plate 111 of the housing 1 extends upward to form a first arc plate 41, a second arc plate 42, a first connecting plate 43 and a second connecting plate 44. The first arc plate 41 has the same diameter and is coaxial with the first pipe body 31. The second arc plate 42 has the same diameter and is coaxial with the second pipe body 32. The orientations of the two sides of the first arc plate 41 are the same as those of the two sides of the second arc plate 42. The two sides of the first arc plate 41 are respectively connected to the two sides of the second arc plate 42 through the first connecting plate 43 and the second connecting plate 44. The first arc plate 41, the second arc plate 42, the first connecting plate 43 and the second connecting plate 44 enclose a second channel 45. The upper end of the second channel 45 is higher than the upper end of the first pipe body 31. The lower end of the second channel 45 is connected and communicates with the upper end of the first channel 33. The first channel 33 and the second channel 45 constitute an exhaust channel, and the lower end of the first channel 33 forms an exhaust port. That is to say, the exhaust port is an annular exhaust port surrounding the water outlet, and the annular exhaust port is arranged adjacent to the water outlet.

[0052] As Figure 4 and Figure 5As shown, the perforated plate 5 is disposed below the lower end of the first pipe body 31. A plurality of perforations 51 are formed in the perforated plate 5. The edge of the perforated plate 5 is connected to a first cylinder body 52 integrally formed therewith. A first annular rib 53 is formed at a position near the lower end on the outer wall of the first cylinder body 52. The portion of the first cylinder body 52 above the first annular rib 53 is inserted into the second pipe body 32. The upper end surface of the first cylinder body 52 abuts against the lower surface of the bottom plate 111, and the upper surface of the first annular rib 53 abuts against the lower end surface of the second pipe body 32. The fixing member 6 includes a second cylinder body 61. A second annular rib 62 is formed at a position near the lower end on the inner wall of the second cylinder body 61. An internal thread is formed in the region of the inner wall of the second cylinder body 61 above the second annular rib 62. An external thread is formed on the outer wall of the second pipe body 32. The upper surface of the second annular rib 62 abuts against the lower surface of the first annular rib 53, and the internal thread on the inner wall of the second cylinder body 61 is screwed together with the external thread on the outer wall of the second pipe body 32, thereby fixing the perforated plate 5 to a position below the lower end of the first pipe body 31. The lower end of the first pipe body 31 does not contact the upper surface of the perforated plate 5, and a water passing gap is formed between the lower end of the first pipe body 31 and the upper surface of the perforated plate 5. The middle region of the upper surface of the perforated plate 5 is recessed downward relative to the edge region, and the middle region of the lower surface of the perforated plate 5 protrudes downward relative to the edge region. Specifically, both the upper surface and the lower surface of the perforated plate 5 are spherical crown-shaped curved surfaces, and the thickness of different regions of the perforated plate 5 is the same.

[0053] As Figure 2 and Figure 4 shown, a first buffer plate 71 facing the hot water inlet joint 21 and a second buffer plate 72 facing the normal temperature water inlet joint 22 are disposed in the housing 1. The lower side edge of the first buffer plate 71 is connected to the bottom plate 111, and one side edge of the first buffer plate 71 is connected to the adjacent side plate 112. The lower side edge of the second buffer plate 72 is connected to the bottom plate 111, and one side edge of the second buffer plate 72 is connected to the adjacent side plate 112. A water passing channel is formed between the first buffer plate 71 and the second buffer plate 72.

[0054] In a state where the water vapor separation box is installed on the faucet, the hot water inlet joint 21 is quickly connected to the hot water pipe, and the normal temperature water inlet joint 22 is quickly connected to the normal temperature water pipe.

[0055] Referring to Figure 2, when the hot water containing water vapor flows into the water-vapor separation cavity 13 through the hot water inlet joint 21, the hot water containing water vapor collides with the first buffer plate 71, and the water vapor in the hot water is separated out. The hot water flows rightward through the water passage between the first buffer plate 71 and the second buffer plate 72, bypasses the second arc plate 42 and flows rightward from both sides of the second arc plate 42, then flows into the first pipe body 31 from the position between the first connecting plate 43 and the second connecting plate 44, and then flows out from the lower end (i.e., the water outlet) of the first pipe body 31, and then passes through the mesh holes 51 on the mesh plate 5 and flows downward. The water vapor accumulates in the upper part of the water-vapor separation cavity 13, enters from the upper end of the second channel 45 and flows downward, then flows through the first channel 33 and flows out from the lower end of the first channel 33, and finally passes downward through the mesh holes 51 at the corresponding positions on the mesh plate 5 and is discharged into the atmospheric environment.

[0056] Since the upper surface of the mesh plate 5 is a spherical crown-shaped curved surface with the middle area sunken downward relative to the edge area, the hot water flowing out from the lower end of the first pipe body 31 can better converge toward the middle and flow out after passing through the mesh holes 51, so that the water flow of the water outlet maintains a good water shape, reducing the risk of water droplet splashing. Since the lower surface of the mesh plate 5 is a spherical crown-shaped curved surface with the middle area protruding downward relative to the edge area, under the action of the surface tension of water and the adhesion force between water and the lower surface of the mesh plate 5, the water is more inclined to converge toward the middle after flowing out from the mesh holes 51 of the mesh plate 5, which is more conducive to the water flow of the water outlet maintaining a good water shape. In addition, the thickness of different areas of the mesh plate 5 is the same, which facilitates the manufacture of the mesh plate 5 and avoids the occurrence of stress concentration easily caused by uneven thickness in different parts of the mesh plate 5.

[0057] The lower end of the first pipe body 31 does not contact the upper surface of the mesh plate 5, and a water passage gap is formed between the lower end of the first pipe body 31 and the upper surface of the mesh plate 5. Through such a setting, when the water flow of the water outlet is large, a part of the water can spread from the water passage gap to the edge of the mesh plate 5 and flow out through the mesh holes 51 in the edge area of the mesh plate 5, so as to meet the water outlet demand of a large water volume.

[0058] The second pipe body 32 is sleeved outside the first pipe body 31, and a first channel 33 with an annular cross-section is formed between the second pipe body 32 and the first pipe body 31, and an exhaust port is formed at the lower end of the first channel 33. Through such a setting, the water vapor is discharged from the annular exhaust port surrounding the water outlet, forming an annular air flow sleeved outside the water flow of the water outlet, that is, forming a protective air layer outside the water column of the water outlet, which can further reduce the risk of water droplets splashing outward from the water flow of the water outlet.

[0059] The exhaust port is arranged adjacent to the water outlet, which can reduce the risk of scalding the human body caused by high-temperature water vapor flowing towards the surrounding human body and improve the safety of use. The exhaust port is arranged adjacent to the water outlet and is a ring-shaped exhaust port surrounding the water outlet, so that water vapor is discharged from the ring-shaped exhaust port surrounding the water outlet, forming a ring-shaped air flow sleeved on the outer circle of the water outlet flow, that is, a protective air layer is formed on the outer circle of the water column, which can further reduce the risk of water droplets splashing outwards from the water outlet flow.

[0060] Refer to Figure 2 , when normal temperature water flows into the water vapor separation cavity 13 through the normal temperature water inlet joint 22, the normal temperature water collides with the second buffer plate 72, and the normal temperature water flows to the right through the water passing channel between the first buffer plate 71 and the second buffer plate 72. The normal temperature water bypasses the second arc plate 42 and flows to the right from both sides of the second arc plate 42, and then flows into the first pipe body 31 from the position between the first connecting plate 43 and the second connecting plate 44, and then flows out from the lower end (i.e., the water outlet) of the first pipe body 31, and then flows downward through the mesh holes 51 on the mesh plate 5.

[0061] In this way, on the basis of meeting the water outlet demand of normal temperature water, there is no need to separately set a normal temperature water outlet, avoiding the situation of increasing the volume of the faucet due to separately setting a normal temperature water outlet, simplifying the structure of the faucet and reducing the volume of the faucet.

[0062] It should be noted that the lower end of the first pipe body 31 does not contact the upper surface of the mesh plate 5, and a water passing gap is formed between the lower end of the first pipe body 31 and the upper surface of the mesh plate 5. This is also a relatively preferred setting method, and adjustments can be made in actual applications. For example, the lower end of the first pipe body 31 contacts the upper surface of the mesh plate 5, and no water passing gap is formed between the lower end of the first pipe body 31 and the upper surface of the mesh plate 5. In addition, both the upper surface and the lower surface of the mesh plate 5 are spherical crown-shaped curved surfaces, and the thickness of different regions of the mesh plate 5 is the same. This is only a relatively preferred setting method, and adjustments can be made in actual applications. For example, both the upper surface and the lower surface of the mesh plate 5 are non-spherical crown-shaped curved surfaces, and the thickness of different regions of the mesh plate 5 is the same, or the upper surface of the mesh plate 5 is a curved surface with the middle region sunken downward relative to the edge region, while the lower surface of the mesh plate 5 is a plane. The edge of the mesh plate 5 can also be connected to the lower end of the second pipe body 32 by bonding, clamping, etc. In addition, the bottom plate 111 of the housing 1 extends upward with a first arc plate 41, a second arc plate 42, a first connecting plate 43, and a second connecting plate 44. The first arc plate 41 has the same diameter and is coaxial with the first pipe body 31, the second arc plate 42 has the same diameter and is coaxial with the second pipe body 32. The orientations of the two sides of the first arc plate 41 are the same as those of the two sides of the second arc plate 42. The two sides of the first arc plate 41 are respectively connected to the two sides of the second arc plate 42 through the first connecting plate 43 and the second connecting plate 44. The first arc plate 41, the second arc plate 42, the first connecting plate 43, and the second connecting plate 44 enclose a second channel 45. This is also a relatively specific setting method, and adjustments can be made in actual applications. For example, in another specific setting method, the bottom plate 111 extends upward with a plurality of ventilation pipes arranged in a circumferential array around the axis of the first pipe body 31. The upper end of each ventilation pipe is communicated with the upper space of the water-vapor separation cavity 13, and the lower end of each ventilation pipe is communicated with the upper end of the first channel 33. The internal channels of all the ventilation pipes form the second channel; in another specific setting method, the bottom plate 111 extends downward with a plurality of first ventilation pipes arranged in a circumferential array around the axis of the first pipe body 31 and extends upward with a plurality of second ventilation pipes arranged in a circumferential array around the axis of the first pipe body 31. The internal channels of all the first ventilation pipes form the first channel, the internal channels of all the second ventilation pipes form the second channel. The upper end of each second ventilation pipe is communicated with the upper space of the water-vapor separation cavity 13, and the lower end of the second ventilation pipe is communicated with the upper end of the first ventilation pipe in a one-to-one correspondence. The lower ends of all the first ventilation pipes form an exhaust port adjacent to the water outlet.

[0063] In another feasible embodiment, the second tube body 32, the first arc plate 41, the second arc plate 42, the first connecting plate 43 and the second connecting plate 44 may not be provided, the edge of the mesh plate 5 is connected to the lower end of the first tube body 31, and an exhaust port is provided on the side or top of the housing 1, and the exhaust port is communicated with the upper space of the water vapor separation chamber 13 through an exhaust pipe.

[0064] In another feasible embodiment, the normal temperature water inlet joint 22 may also not be provided.

[0065] In addition, the present invention also provides a faucet, which includes the water vapor separation box described in any one of the above embodiments.
