Description

Technical Field

[0001] This disclosure relates to a mixing valve, and more particularly to a mixing valve for independently controlling fluid pressure and fluid temperature. Background Technology

[0002] Based on existing mixing valves, water flow and pressure are regulated by rotating a fluid control element, such as a mixing handle, connected to the mixing valve. Rotation of the mixing handle allows for control or regulation of water pressure, or for increasing or decreasing water pressure, while also allowing for adjustment or control of water temperature.

[0003] These existing mixing valves are functionally limited because when the mixing handle is turned to mix hot and cold water, the valve is fully open, thus the pressure is at its maximum and there is no possibility of adjustment. Therefore, when rotating the mixing handle to produce a mixture of hot and cold water, it can only be used at the highest pressure setting. Consequently, existing mixing valves do not allow pressure adjustment when using hot and cold water mixing.

[0004] The aim is usually to overcome or improve one or more of the aforementioned difficulties, or at least to provide a useful alternative to them. Summary of the Invention

[0005] One or more embodiments of the present invention include a mixing valve comprising: a first fluid flow window; a second fluid flow window; a first plate corresponding to the first fluid flow window; and a second plate corresponding to the second fluid flow window; wherein the first plate is at least partially located within a channel defined by and extending through the second plate, the plate being independently movable; wherein moving the first plate controls a first aspect of the fluid; and wherein moving the second plate controls a second aspect of the fluid.

[0006] In some embodiments, a first aspect of controlling the fluid includes changing the first overlap between the first plate and the first fluid flow window.

[0007] In some embodiments, a second aspect of controlling the fluid includes changing the second overlap between the second plate and the second fluid flow window.

[0008] In some embodiments, the mixing valve further includes a fluid flow window that defines first and second fluid flow windows.

[0009] In some embodiments, the mixing valve further includes a third fluid flow window; wherein the second plate further corresponds to the third fluid flow window; wherein moving the second plate further controls a third aspect of the fluid.

[0010] In some embodiments, the mixing valve further includes a fluid flow window that defines first, second, and third fluid flow windows.

[0011] In some embodiments, a third aspect of controlling the fluid includes changing the third overlap between the second plate and the third fluid flow window.

[0012] In some embodiments, when the second plate moves along the first direction, it causes a second overlap to increase and a third overlap to decrease.

[0013] In some embodiments, when the second plate rotates in the second direction, it causes a second overlap to increase and a third overlap to increase.

[0014] In some embodiments, rotating the second plate in a first direction causes the temperature of the fluid leaving the valve to rise.

[0015] In some embodiments, rotating the second plate in the second direction causes a decrease in the temperature of the fluid leaving the valve.

[0016] In some embodiments, the temperature can be preset by rotating the second plate in a first or second direction without allowing any fluid to leave the mixing valve.

[0017] In some embodiments, the second plate defines a second flow control opening, wherein as the second plate moves, the second overlap is controlled by a second alignment between the second flow control opening and the second fluid flow window.

[0018] In some embodiments, the second plate defines a third flow control opening, wherein, as the second plate moves, a third overlap is controlled by a third alignment between the third flow control opening and the third fluid flow window.

[0019] In some embodiments, the first aspect of the fluid is the flow rate of the fluid through the mixing valve; the second aspect of the fluid is the volume of a relatively hot fluid; and the third aspect of the fluid is the volume of a relatively cold fluid.

[0020] In some embodiments, rotating the first plate in a first direction increases the flow rate of fluid through the valve.

[0021] In some embodiments, rotating the first plate in a second direction reduces the flow rate of fluid through the valve.

[0022] In some embodiments, the mixing valve further includes a hot fluid inlet and a cold fluid inlet.

[0023] In some embodiments, the hot fluid inlet and the cold fluid inlet are check valves to ensure that fluid flows through the mixing valve in only one primary direction.

[0024] In some embodiments, the check valve essentially restricts the backflow of fluid into one or more supply lines.

[0025] In some embodiments, the mixing valve further includes a first rotor configured to engage with a first plate; and a second rotor configured to engage with a second plate.

[0026] In some embodiments, the mixing valve further includes a first handle configured to engage with a first rotor to enable a user to control a first aspect of the fluid; and a second handle configured to engage with a second rotor to enable a user to control a second aspect of the fluid.

[0027] In some embodiments, the second handle is further configured to enable the user to control a third aspect of the fluid.

[0028] In some embodiments, the mixing valve is fluidly connected to a fluid source.

[0029] In some embodiments, the second plate includes an inner edge defining a channel extending through the second plate and defining a second fluid flow window.

[0030] In some embodiments, the second fluid flow window is a notch.

[0031] In some embodiments, the inner edge includes a lip configured to overlap with at least the second fluid flow window; and wherein the lip includes:

[0032] The first end, which defines the corresponding first end of the notch; and

[0033] The second end defines the corresponding second end of the notch.

[0034] In some embodiments, the lip extends substantially uniformly around the inner edge of the second plate, from a first end of the lip to a second end of the lip.

[0035] In some embodiments, the valve further includes a third fluid flow window, wherein:

[0036] The second plate can be configured such that the lip can completely block the second fluid flow window or the third fluid flow window. Attached Figure Description

[0055] According to some embodiments, the mixing valve 100 includes or defines a first fluid flow window 322; a second fluid flow window 325; a first plate 352 corresponding to the first fluid flow window 322; and a second plate 354 corresponding to the second fluid flow window 325. The first plate 352 is at least partially located within a channel defined by and extending through the second plate 354, and the plate is independently movable. Moving the first plate 352 controls a first aspect of the fluid; and / or moving the second plate 354 controls a second aspect of the fluid. The term "control" includes changing an existing aspect of the fluid that has flowed or may be allowed to flow through the mixing valve 100. The term "control" also includes setting or presetting / preselecting multiple aspects of the fluid before or during its flow through the mixing valve 100.

[0056] For example, a mixing valve 100 is included in a fixture 500 in a bathroom or kitchen, allowing independent control of the temperature and pressure of a fluid (such as water) flowing through the mixing valve 100. The mixing valve 100 includes a first fluid control element 110 defining a channel extending along its length; and a second fluid control element 120 sized to extend through the channel of the first fluid control element 110. When the second fluid control element 120 is inserted through the channel defined by the first fluid control element 110, both the first and second fluid control elements are independently rotatable about a central axis. Rotation of the first fluid control element 110 moves a first plate 352, thereby controlling a first aspect of the fluid flowing through the mixing valve 100. Furthermore, rotation of the second fluid control element 120 moves a second plate 354, thereby controlling a second aspect of the fluid flowing through the mixing valve 100. According to some embodiments, the first fluid control element 110 and / or the second fluid control element 120 may be rotors. The rotor may include one or more ridges for engaging with their respective handle portions, as discussed in more detail below.

[0057] According to some embodiments, the mixing valve 100 may include or contain a check element 215 configured to ensure that fluid is allowed to flow into the mixing valve only through inlets 304, 306, and is not allowed to flow back from inlets 304, 306 into the conduit supplying the fluid. The check element 215 may be configured to allow at least one of a first or second aspect of fluid flow to be preset, while preventing any fluid from flowing out of the mixing valve 100.

[0058] A first aspect of the fluid flowing through the mixing valve 100 is the flow rate of the fluid flowing through the mixing valve 100, wherein moving the first plate 352 in a first direction increases the flow rate of the fluid through the mixing valve 100, and moving the first plate 352 in a second direction decreases the flow rate of the fluid through the mixing valve 100. In some embodiments, controlling the volume of water moving through the mixing valve 100 may have the effect of increasing or decreasing the pressure of the fluid being ejected from an outlet pipe or an outlet fixture (such as a faucet or shower head).

[0059] The second aspect of the fluid flowing through the mixing valve 100 is the amount or volume of the relative hot fluid passing through the mixing valve 100, wherein rotating the second plate 354 in the first direction increases the amount of the relative hot fluid passing through the mixing valve 100, and rotating the second plate 354 in the second direction decreases the amount of the relative hot fluid passing through the mixing valve 100.

[0060] The mixing valve may further include a third fluid flow window 330, and the second plate 354 may further correspond to the third fluid flow window. According to an embodiment including the third fluid flow window 330, a third aspect of the fluid is controlled when the second plate is moved. According to some embodiments, the third aspect of the fluid is the volume of a relatively cold fluid. Therefore, by moving the second plate, for example by rotating the second fluid control element 120, the overall temperature of the fluid flowing out of the mixing valve 100 can be controlled.

[0061] In other words, the mixing valve 100 provides the user of the mixing valve 100 with the ability to preset the desired fluid temperature using the second plate 354 and / or the second fluid control element 120, and to open and close and adjust the pressure of the fluid flowing out of the connected outlet pipe using the first plate and / or the first fluid control element 110.

[0062] Compared to existing systems, the mixing valve 100 of this invention reduces water waste by allowing the water temperature to be pre-selected before the water flow is "turned on," or by otherwise selecting the mixing ratio between cold and heated liquids. This eliminates the need for temperature adjustment as the water flows. The mixing valve 100 also allows the mixed liquids to be delivered from pipes (such as faucets or shower heads) at different pressures (not the maximum pressure the system can withstand), thereby reducing the amount of water that must flow through the system to ensure an adequate temperature.

[0063] The mixing valve 100 of the present invention additionally or alternatively provides a safer system than existing mixing valves. The mixing valve 100 of the present invention allows for water temperature regulation before any water is allowed to flow out of the system. This may prevent users from being scalded by water (or other fluids at dangerous temperatures) during temperature regulation.

[0064] like Figure 4As shown, the mixing valve 100 may be incorporated into or otherwise included in the fixture 200, such as a bathroom sink faucet, kitchen sink faucet, shower faucet, bathtub faucet, outdoor faucet, or any other type of fixture that may require mixing fluids of different properties.

[0065] like Figures 2A to 2C As shown, the mixing valve 100 includes a housing 205, a mixing and control component 210, and a check component 215. The housing 205 may be placed on some or all of the mixing and control component 210 and / or the check component 215 to protect or otherwise cover them. The mixing and control component 210 may include a fluid mixing component 260 and / or a flow mixing component 270. The fluid mixing component 260 may include the second fluid control element 120 and the second plate 354. The flow mixing component 270 may include a first fluid control element 110 and / or a first plate 352. The mixing and control component 210 may include a sleeve 225 configured to extend at least partially between the first fluid control element 110 and the second fluid control element 120, for example, for liquid sealing and / or reducing friction between moving parts.

[0066] The mixing valve 100 may include a flow window plate 240 defining first, second, and / or third fluid flow windows 322, 325, and / or 330. A check valve component 215 may include a check housing 245 and / or one or more check inlets 250. One or more check inlets 250 may be one-way flow valves configured to allow fluid to enter the mixing valve 100 but not to allow fluid backflow into the fluid conduit from which the fluid flows. In some embodiments, the check inlet 250 includes a biasing portion biased such that when a force (e.g., fluid pressure) is applied to the portion in a first direction, the portion may be configured to move in that first direction to allow fluid to flow through the check inlet 250 into the mixing valve 100. The biasing portion may be additionally configured not to move (or otherwise configured not to move or otherwise resist fluid flow) when the check inlet 250 is subjected to a force in a second direction opposite to the first direction, thereby preventing fluid from flowing in the direction of the second force, for example, backflow into the fluid supply conduit.

[0067] In some embodiments, the mixing valve 100 may include one or more mesh screens (not shown). In some embodiments, the mesh screens are located between the check member and the fluid inlet supplying fluid to the mixing valve 100. In some embodiments, the mesh screens may be located between the check member 215 and the flow window 240.

[0068] As shown in the figure Figure 3A Depicting along Figure 2AThe mixing valve, as shown in the cross section 300 of the BB line, may include a first inlet 304 and a second inlet 306. In some embodiments, inlets 304, 306 may be hot fluid inlets and / or cold fluid inlets. In some embodiments, inlet 304 is configured to receive hot fluid passing through it. In some embodiments, inlet 306 may be configured to receive cold fluid passing through it. According to some embodiments, fluid enters the mixing valve 100 through one or more inlets 304, 306 and exits the mixing valve 100 through a fluid outflow window 302. The mixing valve may include a seal 308 configured to ensure that fluid entering the mixing valve 100 does not mix with fluid leaving the mixing valve 100 and / or that fluid entering through the first inlet 304 does not mix with fluid entering through the second inlet 306. Inlets 304, 306 may be unidirectional flow inlets, such that water entering the mixing valve is not allowed to flow out of the mixing valve through inlets 304, 306. The check valve 250 may be additionally configured to restrict fluid backflow from the mixing valve 100.

[0069] like Figure 3B As shown, the depiction is along... Figure 2A The cross-section 320 of the CC line shown indicates that the mixing valve includes a second fluid flow window 325 and / or a third fluid flow window 330. (As shown...) Figure 3B As shown, the second and third fluid flow windows 325 and 330 can be curved windows. Figure 3B As shown, the shape of the first fluid flow window 322 can be part of a circle.

[0070] In some embodiments, the first fluid flow window 322 has a different shape than the second and third fluid flow windows 325 and 330. In some embodiments, the first, second, and third fluid flow windows 322, 325, and 330 all have the same shape. In some embodiments, the first, second, and third fluid flow windows 322, 325, and 330 all have different shapes. In some embodiments, the second and third fluid flow windows 325 and 330 have the same shape. In some embodiments, the second and third fluid flow windows 325 and 330 have different shapes. However, those skilled in the art will understand that windows 322, 325, and 330 can take any suitable shape.

[0071] According to the present invention, fluid flow windows 322, 325, 330 are positioned or defined by a mixing valve such that fluid flow entering the mixing valve 100 through the second and / or third fluid flow windows 325, 330 is substantially fluidly isolated from fluid flow exiting the mixing valve through the first fluid flow window 322. Thus, the mixing of fluids (e.g., hot and cold fluids) can be precisely controlled by the movement (e.g., rotation) of the second plate 354. To facilitate fluid isolation between the second and / or third fluid flow windows 325, 330 and the first fluid flow window 322, the mixing valve may include one or more seals 275 (…). Figure 2C ).

[0072] like Figure 3C As shown, the depiction is along... Figure 2A The cross-section 350 of the DD line shown indicates that the mixing valve 100 includes a first plate 352 and a second plate 354. The first plate 352 may include, define, or otherwise include a first flow control opening 358. According to some embodiments, the first flow control opening 358 has a shape that at least partially corresponds to a first fluid flow window 322. The second plate 354 may include, define, or otherwise include a second flow control opening 356. The second flow control opening 354 has a shape that at least partially corresponds to at least a second fluid flow window 325. In some embodiments, the second flow control opening 356 has a shape that at least partially corresponds to the shapes of both the second fluid flow window 325 and the third fluid flow window 330.

[0073] like Figure 3C As shown, the first and second plates 352, 354 are primarily circular, or have a predominantly circular shape. According to other embodiments, the first and second plates 352, 354 may have any other shape suitable for blocking and / or aligning (as described herein) the first or second fluid flow windows 322, 325. According to some embodiments, the shape of the first and / or second plates 352, 354 may include square, rectangular, oval / ovoid, rhomboid, triangular, octagonal, pentagonal, hexagonal, heptagonal, and / or non-angular shapes, etc.

[0074] like Figure 3CAs shown, the second plate 354 includes a second fluid flow opening 356. The second fluid flow opening 356 may include an open cut or an open notch structure. The second plate 354 may include an outer edge 364 and an inner edge 366. The distance between the outer edge 364 and a center point of the second plate 354 (i.e., the radius of the circle defined by the outer edge 364) may be greater than the distance between the inner edge 366 and the same center point of the second plate 354 (i.e., the radius of the circle defined by the inner edge 366). The inner edge 366 may define an aperture substantially the same size as the radius of the circle defined by the inner edge 366, which extends through the second plate 354. When the second fluid flow opening 356 includes an open notch structure, the second plate may include a first flow opening edge 360, a second flow opening edge 362, and / or a third flow opening edge 368. The third flow opening edge may include a curve that includes a gradient (or curvature) approximately the same as the gradient or curvature of the outer edge 364 and / or the inner edge 366. Accordingly, the second flow control opening 356 may have a shape or curvature that is substantially the same as the gradient or curvature of the outer edge 364 and / or the inner edge 366.

[0075] In some embodiments, the second plate 354 includes a lip 372. The lip may include a first flow opening edge 360, a second flow opening edge 362, and an inner edge 366. The first flow opening edge 360 ​​and the second flow opening edge 362 respectively define the ends of the lip 372. The first flow opening edge 360 ​​and the second flow opening edge 362 define the location where the lip ends and the second flow control opening 356 begins. The lip 372 may extend around the entire inner edge 366 of the second plate 354. The lip may be at least partially defined by the inner edge 366. In some embodiments, the lip 372 may include a substantially uniform gradient and / or curvature. The lip 372 may be configured and / or sized to overlap so as to completely or substantially completely cover the second fluid flow window 325 and / or the third fluid flow window 330. The lip 372 may be configured to overlap and / or obscure, cover, or otherwise obscure the second fluid flow window 325 and / or the third fluid flow window 330.

[0076] The second fluid flow window 356 can be configured or otherwise resized to be fully aligned with either the second fluid flow window 325 or the third fluid flow window 330. In other words, the second fluid flow window 356 can be configured or otherwise resized so that it cannot be fully aligned with either the second fluid flow window 325 or the third fluid flow window 330 simultaneously. Accordingly, the valve 100 can be configured such that, in any permissible configuration or arrangement of the second plate 354, the lip 372 can completely block only either the second fluid flow window 325 or the third fluid flow window 330. In some embodiments, where the lip 372 can completely block only either the second fluid flow window 325 or the third fluid flow window 330 in any permissible configuration or arrangement of the second plate 354, the backflow and / or the first plate 352 (when the first fluid flow window 322 does not overlap with the first flow control opening 358) restrict fluid exit before the user desires fluid to exit the valve 100. This ensures that fluid properties (such as fluid temperature) can be set before fluid is allowed to leave valve 100, without completely blocking the second fluid flow window 325 and the third fluid flow window 330. This simplifies the design of the second plate 354.

[0077] like Figure 3D As shown, it illustrates along such Figure 2A The cross-section 370 of the EE line shown indicates that the mixing valve 100 includes a first fluid control element that extends at least partially through or is at least partially located within the second fluid control element 120.

[0078] In use, a fluid (e.g., water) can enter the mixing valve 100 through one or more inlets 304, 306. In some embodiments, the fluid entering through one of the inlets (e.g., the first inlet 304) may be relatively hotter than the fluid entering through the second inlet 306. The fluids entering through the first and second inlets 304, 306 can be kept separate by a seal 308.

[0079] After entering the mixing valve 100, the fluid entering through the first inlet 304 is allowed to flow through the second fluid flow window 325. Alternatively, after entering the mixing valve 100, the fluid entering through the second inlet 306 is allowed to flow through the third fluid flow window 330.

[0080] The volume of fluid flowing through the second fluid flow window 325 can be altered or otherwise controlled by moving the second plate 354. In possible locations, the second fluid flow window 325 can be substantially unobstructed by the second plate 354, thereby allowing the maximum volume of fluid to pass through it. To alter the volume of fluid flowing through the second fluid flow window 325, the second plate 354 can be moved (e.g., rotated) to partially or completely obstruct or otherwise partially or completely overlap the second fluid flow window 325. When the plate 354 substantially completely obstructs or aligns with the second fluid flow window 325, the flow of fluid through the second fluid flow window 325 is substantially stopped.

[0081] In some embodiments, in order to increase or decrease the volume of fluid passing through the second fluid flow window 325, and as Figures 3A-3D As shown, the second flow control opening 356 can be moved (e.g., rotated) to change the alignment or overlap between the second flow control opening 356 and the second fluid flow window 325. In some embodiments, the alignment or overlap includes the proportion of the fluid flow window that is obscured or otherwise covered by a corresponding plate.

[0082] In one possible position, the second flow control opening 356 may not be aligned with or overlap with the second fluid flow window 325, and the second plate 354 thus substantially or completely blocks the flow of fluid through the second fluid flow window 325. As the second plate 354 moves (e.g., rotates) from the substantially completely blocked position, the second flow control opening 356 gradually aligns more and more with the second fluid flow window 325 until the second flow control opening 356 is fully aligned with the second fluid flow window 325, thereby allowing the maximum volume of fluid to flow through the second fluid flow window 325.

[0083] According to some embodiments, the volume of fluid flowing through the third fluid flow window 330 can be controlled in a similar manner to the volume of fluid flowing through the second fluid flow window 325.

[0084] The volume of fluid flowing through the third fluid flow window 330 can be altered or otherwise controlled by moving the second plate 354. In possible locations, the third fluid flow window 330 can be substantially unobstructed by the second plate 354, allowing the maximum volume of fluid to pass through it. To alter the volume of fluid flowing through the third fluid flow window 330, the second plate 354 can be moved (e.g., rotated) to partially or completely obstruct or otherwise partially or completely overlap the third fluid flow window 330. When the plate 354 substantially completely obstructs or aligns with the third fluid flow window 330, the flow of fluid through the third fluid flow window 330 is substantially stopped.

[0085] In some embodiments, in order to increase or decrease the volume of fluid passing through the third fluid flow window 330, and as Figures 3A-3D As shown, the second flow control opening 356 can be moved (e.g., rotated) to change the alignment or overlap between the second flow control opening 356 and the third fluid flow window 330.

[0086] In one possible position, the second flow control opening 356 may not be aligned with or overlap with the third fluid flow window 330, thus the second plate 354 substantially or completely blocks the flow of fluid through the third fluid flow window 330. As the second plate 354 moves (e.g., rotates) from the substantially completely blocked position, the second flow control opening 356 gradually aligns more and more with the third fluid flow window 330 until the second flow control opening 356 is fully aligned with the third fluid flow window 330, thereby allowing the maximum volume of fluid to flow through the third fluid flow window 330.

[0087] In some embodiments, when the second plate 354 moves (e.g., rotates) in a first direction, the second plate 354 increases its alignment with the second fluid flow window 325 and correspondingly decreases its alignment with the third fluid flow window 330. Alternatively, when the second plate 354 moves (e.g., rotates) in a second direction, the second plate 354 decreases its alignment with the second fluid flow window 325 and correspondingly increases its alignment with the third fluid flow window 330. Thus, when the second plate 354 is moved (e.g., rotated), the proportion of fluid flowing through the mixing valve 100 is controlled. For example, as the alignment or obstruction of a particular fluid flow window increases, less fluid flows through that particular fluid flow window. Conversely, when the alignment or obstruction of one particular fluid flow window increases, the alignment or obstruction of another fluid flow window also increases accordingly. Thus, the proportion of one fluid to another can be changed by moving the second plate 354.

[0088] In one configuration, when the second plate 354 is at a first limit of its movable range (e.g., rotatable range), the second plate 354 substantially completely blocks the second fluid flow window 325 and does not overlap or align with the third fluid flow window 330. In another configuration, when the second plate 354 is at a second limit of its movable range (e.g., rotatable range), the second plate 354 substantially completely blocks the third fluid flow window 330 and does not overlap or align with the second fluid flow window 325. Thus, when the second plate 354 is at either the first or second limit of its movable range (e.g., rotatable range), the fluid passing through the mixing valve 100 substantially originates only from any fluid flow window that is not substantially completely blocked.

[0089] According to some embodiments, the fluid flowing through the second fluid flow window is relatively hot water, the fluid flowing through the third fluid flow window is relatively cold water, and the temperature of the fluid leaving the mixing valve 100 can be controlled by changing the amount of each fluid flowing through the mixing valve 100. In this specific embodiment, the temperature can be controlled independently of the fluid pressure.

[0090] According to some embodiments, the mixing valve 100 may include a third plate (not shown), wherein the third plate corresponds to a third fluid flow window 330. When the third plate corresponds to the third fluid flow window 330, the second plate 354 may not correspond to the third fluid flow window 330. In other words, when the mixing valve 100 includes the third plate, the configuration or shape of the second plate 354 must not partially or otherwise obstruct or align the third fluid flow window 330.

[0091] The third plate can be configured to block, align, or otherwise interact with the third fluid flow window 330 in the same or similar manner as the second plate 354 blocking, aligning, or otherwise interacting with the second fluid flow window 325.

[0092] In some embodiments, when the second plate 354 is moved (e.g., rotated), the third plate can also be moved (e.g., rotated). In some embodiments, both the second plate 354 and the third plate are movably (e.g., rotatably) connected to the second fluid control element 120, such that when the fluid control element 120 is moved (e.g., rotated), both the second plate 354 and the third plate can be moved. When the second plate 354 is moved (e.g., rotated), the third plate can be moved (e.g., rotated) by a similar or substantially similar distance.

[0093] According to some embodiments, when the second plate 325 and the third plate move (e.g., rotate) along a first direction, the degree of overlap or alignment between the second plate 354 and the second fluid flow window 325 may be reduced, and correspondingly, the degree of overlap between the third plate and the third fluid flow window 330 may be increased; thereby increasing the fluid volume entering the mixing valve 100 through the second fluid flow window 325 and reducing the fluid volume entering the mixing valve 100 through the third fluid flow window 330.

[0094] Alternatively or additionally, when the second plate 325 and the third plate move (e.g., rotate) in the second direction, the overlap or alignment between the second plate 354 and the second fluid flow window 325 can be increased, and correspondingly, the overlap between the third plate and the third fluid flow window 330 can be decreased; thereby reducing the volume of fluid entering the mixing valve 100 through the second fluid flow window 325 and increasing the volume of fluid entering the mixing valve 100 through the third fluid flow window 330.

[0095] The third plate may include a third flow control opening (not shown) configured to block, align, or otherwise interact with the third fluid flow window 330 in the same or similar manner as the second flow control opening 356 described above, blocking, aligning, or otherwise interacting with the second fluid flow window 325.

[0096] After the fluids from the second and / or third fluid flow windows 325, 330 are mixed in proportions dependent on the positions of the second plate 354 and / or the third plate, the mixed fluid is then guided through the first fluid flow window 322. The volume of fluid allowed to pass through the first fluid flow window 322 is controlled by the position of the first plate 352.

[0097] The first plate 352 is configured to block, align, or otherwise interact with the first fluid flow window 322. When the first plate 352 moves (e.g., rotates) in a first direction, the overlap between the first plate 352 and the first fluid flow window 322 increases, thereby limiting the volume of fluid flowing through the first fluid flow window 322 and reducing the pressure of the fluid leaving the outlet pipe (e.g., a shower head or faucet).

[0098] Alternatively or additionally, when the first plate 352 moves (e.g., rotates) in the second direction, the overlap between the first plate 352 and the first fluid flow window 322 is reduced, thereby allowing a larger volume of fluid to flow through the first fluid flow window 322, thus increasing the pressure of the fluid leaving the outlet pipe (e.g., a shower head or faucet). After the fluid passes through the first fluid flow window 322, the fluid flows through the fluid outlet window 302 and exits from the mixing valve 100.

[0099] According to some embodiments, the fluid flowing through the mixing valve 100 can follow the following... Figure 4 The path shown. Figure 4 This includes a cross-sectional portion 402 that allows a view of the internal components and / or structure of the valve 100. Those skilled in the art will understand that, in operation, the valve 100 will not include the cross-sectional portion 402.

[0100] At 410, fluid enters the mixing valve through at least one of inlet 304 and inlet 306. The check valve 215 is configured to prevent backflow of the fluid into the fluid conduit from which it flows. The check valve 215 can alter or adjust one aspect of the fluid without requiring fluid to exit the mixing valve. For example, the check valve 215 can alter the mixing ratio of the fluid flowing through inlet 304 and the fluid flowing through inlet 306 (e.g., controlling the temperature of the fluid exiting the mixing valve 100) without requiring fluid to exit the mixing valve 100.

[0101] In some embodiments, when the first fluid flow window 322 is completely blocked by the first plate 352 (i.e., when fluid is not allowed to flow through and out of the mixing valve 100), the mixing valve 100 may generate a certain degree of internal pressure, or at least a certain degree of internal restriction, which, when combined with the bias of the check member 215, substantially prevents fluid from entering the mixing valve 100 through the inlets 304, 306.

[0102] In some embodiments, once fluid enters the mixing valve 100 at 410, it enters at least one of the second fluid flow window 325 and the third fluid flow window 330 at 420. Figure 4 As shown, the fluid flowing through inlet 304 flows to the second fluid flow window 325. The fluid flowing through inlet 306 flows to the third fluid flow window 330. At 420, the position of the second plate (or, in some embodiments, the third plate) controls the volume of fluid allowed to flow through the second and third fluid flow windows 325, 330.

[0103] After passing through the second and third fluid flow windows 325, 330, the fluids that have passed through each of the respective second and third fluid flow windows 325, 330 are allowed to merge or otherwise mix at 430.

[0104] Once the fluids are mixed at 430, the fluids are directed through the first fluid flow window 322 at 440. The position of the first plate 352 will limit the volume of the mixed fluid allowed to flow through the first fluid flow window 322.

[0105] Under the pressure set at the position of the first plate 352, the mixed fluid is allowed to flow out of the mixing valve 100 through the fluid outlet window 302 at 450.

[0106] like Figure 5A and 5B As shown, the fixing device 500 includes a wall-mounted body 510. The fixing device 500 includes a mixing valve 100. The fixing device 500 includes a locking nut 520. The fixing device includes a rear plate 525. The fixing device 500 includes a sleeve 530. The fixing device 500 includes a first handle 535. The fixing device 500 includes a second handle 540.

[0107] In some embodiments, the wall-mounted housing 510 may be a waterproof housing configured to receive two or more fluids from two or more fluid sources and direct the two or more fluids to the mixing valve 100 for mixing. For example, the wall-mounted housing 510 may define a first inlet 512, a second inlet 514, and a mixing outlet 516. The first inlet 512 may be a hot fluid inlet configured to receive, for example, hot water, heated water, or relatively hot water. The second inlet 514 may be a cold fluid inlet configured to receive, for example, cold water, cooled water, or unheated water, or relatively cold water. The mixing outlet 516 may be configured to direct the mixed fluid out of the wall-mounted housing 510, for example, into a fluid conduit, delivering it to a fluid outlet, for example, a water pipe (not shown) fluidly connected to a shower head (shown) or faucet (not shown). The wall-mounted housing 510 may define a mixing valve receiving area 518 configured to receive the mixing valve 100.

[0108] The locking nut 520 is configured to engage with the embedded wall body 510 to secure the mixing valve 100 within the mixing valve receiving area 518. For example, the locking nut 520 may define threads configured to engage with corresponding threads defined by the embedded wall body 510, thereby capturing at least a portion of the mixing valve 100, such as the valve body 130, within the mixing valve receiving area 518.

[0109] In some embodiments, the wall-mounted body 510 is installed in a structure such as a wall or workbench, and holes may be made in the structure so that a portion of the mixing valve 100 protrudes through it. In this case, the back plate 525 may cover the holes formed in the structure.

[0110] The sleeve 530 is configured to fit onto a portion of the embedded wall body 510 to cover and / or conceal that portion. For example, a portion of the embedded wall body 510, such as the portion defining the mixing valve receiving area 518, can be covered by sliding the sleeve 530 onto it. In some embodiments, the sleeve 530 may be configured to engage and / or mate with the rear plate 525 and / or the embedded wall body 510.

[0111] The first handle 535 is configured to engage with the first fluid control element 110. In some embodiments, the first fluid control element 110 may define a set of splines configured to engage with a corresponding spline receiving area (not shown) defined by the first handle 535.

[0112] The second handle 540 is configured to engage with the second fluid control element 120. In some embodiments, the second fluid control element 120 may define a set of splines configured to engage with a corresponding spline receiving area (not shown) defined by the second handle 540.

[0113] like Figures 5A-5D As shown, the second fluid control element 120 may be a cylinder. The second fluid control element 120 may include an outer surface defining one or more sets of teeth or splines. Furthermore, the second fluid control element 120 includes an inner surface defining a channel that extends at least partially along the length of the second fluid control element 120, and, according to some embodiments, extends entirely along the length of the second fluid control element 120. The splines may be configured to engage with corresponding teeth or splines of the second handle 540 such that when the second handle 540 is rotated, the second fluid control element 120 rotates accordingly, thereby causing movement (e.g., rotation) of the second plate 354 and / or the third plate.

[0114] The first fluid control element 110 may be a cylinder, its size and shape configured to fit into a channel defined by the second fluid control element 120. In some embodiments, the first fluid control element 110 extends through the channel such that the distal end of the first fluid control element 110 terminates outside the distal end of the second fluid control element 120.

[0115] According to some embodiments, the outer surface of the first fluid control element 110 defines at least one set of teeth or splines configured to engage with the first handle 535. The splines may be configured to engage with corresponding teeth or splines of the first handle 535 such that when the first handle 535 is rotated, the first fluid control element 110 rotates accordingly, thereby moving the first plate 352.

[0116] In some embodiments, when the first fluid control element 110 is inserted through the channel of the second fluid control element 120, the first fluid control element 110 can rotate freely independently of the second fluid control element 120. Similarly, when the first fluid control element 110 is inserted through the channel of the second fluid control element 120, the second fluid control element 120 can rotate freely independently of the first fluid control element 110. In other words, rotation of either the first fluid control element 110 or the second fluid control element 120 will not cause a corresponding rotation of the other fluid control element.

[0117] like Figure 5C and 5D As shown, the first handle 535 (and therefore the first fluid control element 110 and the first plate 352) is independently rotatable relative to the second handle 540 (and therefore the second fluid control element 120 and the second plate 354 and / or the third plate). Figure 5C As shown, the first handle 535 is displayed in the OFF position, where fluid is now permitted or enabled to flow through the mixing valve 100. Figure 5C As shown, the second handle 540 is in a 50:50 split state, wherein the ratio of fluid entering the mixing valve 100 from the second fluid flow window 325 and the third fluid flow window 330 is approximately 50:50.

[0118] According to some embodiments, the orientation of the first handle 535 and / or the second handle 540 may be different. Figure 5C and 5D The orientation shown. In some embodiments, the first handle 535 and / or the second handle 540 may be different from the orientation shown. Figures 5A to 5D The shape shown is as indicated. For example, in some embodiments, the handle 540 may be a circular dial or a knob. In some embodiments, the second handle 540 may include one or more protrusions, or may define one or more shapes, such as grooves, indentations, knurling, or any other suitable shape or texture.

[0119] Those skilled in the art will understand that the position and / or orientation of the first handle 535 and / or the second handle 540 will depend on the orientation of the handles being fixed and / or otherwise connected to the fixing device 500 and / or the overall shape of the handles 535, 540.

[0120] like Figure 5D As shown, the first handle 535 rotates clockwise, which moves the first plate 352 so that the overlap between the first plate 352 and the first fluid flow window 322 is relatively... Figure 5C The position shown is relatively smaller, thereby increasing the pressure of the fluid flowing out of the mixing valve 100. For example... Figure 5D As shown, the first handle 535 may be in the 50% pressure position. (As...) Figure 5D As shown, the second handle 540 rotates counterclockwise, which reduces the overlap between the second plate 354 and the second fluid flow window 325 and increases the overlap between the second plate 354 (or the third plate) and the third fluid flow window 330, thereby increasing the temperature of the fluid leaving the mixing valve 100 in this embodiment.

[0121] According to some embodiments, one or more components of the fastening device 500 may be detachably replaceable. In some embodiments, the sleeve 530 may be detachably replaceable. In some embodiments, the first handle 535 may be detachably replaceable. In some embodiments, the second handle 540 may be detachably replaceable. Detachable replacement components of the fastening device may be removed and replaced to alter the appearance or style of the fastening device 500. Altering the appearance or style of the fastening device 500 may include changing the material used to manufacture one or more components, such as solid steel, brushed steel, solid brass, brushed brass, solid nickel, brushed nickel, coated steel, coated brass, coated nickel, or any other suitable material. Altering the appearance or style of the fastening device 500 may include changing the shape of any one or more components. Altering the appearance or style of the fastening device 500 may include changing the size of any one or more components. Altering the appearance or style of the fastening device 500 may include changing the surface treatment of any one or more components. Altering the appearance or style of the fastening device 500 may include changing the texture of any one or more components.

[0122] According to some embodiments, such as Figure 6A and 6B As shown, the second handle 540 may include, define, or otherwise include additional features or textures, such as the described knockling.
