[0041] like Figure 1 As shown, in the first aspect, the embodiments of the present application provide a mixing valve 100, which relates to the field of faucet technology and is primarily used in faucets. Of course, it can also be used in industrial pipelines, water dispensers, etc., and the application scenarios of the mixing valve 100 are not specifically limited here. For the convenience of description, the mixing valve 100 is used in a faucet as an example for explanation.

[0042] Combine Figures 2 to 4 As shown, the mixing valve 100 provided in this embodiment includes a fixed part 110 and a movable part 120 .

[0043] The fixing member 110 is provided with a first water inlet hole 111, a second water inlet hole 112, and a water outlet hole 113, which are separated from each other in pairs. That is, the first water inlet hole 111 and the second water inlet hole 112 are separated, and the water outlet hole 113 is separated from the first water inlet hole 111 and the second water inlet hole 112. The first water inlet hole 111 and the second water inlet hole 112 are respectively extended along the circumference of the fixing member 110. The movable part 120 is movably attached to the fixed part 110 and is provided with a water guide hole 121 connected to the water outlet hole 113. The hole wall of the water guide hole 121 includes a first curved wall surface 1211 and a second curved wall surface 1212 arranged opposite to each other, two first connecting wall surfaces 1213 arranged opposite to each other, and two second connecting wall surfaces 1214 arranged opposite to each other; the first curved wall surface 1211 is connected between the two first connecting wall surfaces 1213, the second curved wall surface 1212 is connected between the two second connecting wall surfaces 1214, and each first connecting wall surface 1213 is connected to a second connecting wall surface 1214.

[0044] When the movable part 120 moves to the first preset position relative to the fixed part 110, the first water inlet hole 111 and the second water inlet hole 112 are closed by the movable part 120; when the movable part 120 moves to the second preset position relative to the fixed part 110, the first water inlet hole 111 is connected to the water guide hole 121, and the second water inlet hole 112 is closed by the movable part 120; when the movable part 120 moves to the third preset position relative to the fixed part 110, the first water inlet hole 111 and the second water inlet hole 112 are connected to the water guide hole 121 respectively; when the movable part 120 moves to the fourth preset position relative to the fixed part 110, the first water inlet hole 111 is closed by the movable part 120, and the second water inlet hole 112 is connected to the water guide hole 121.

[0045] It should be noted that the working principle of the mixing valve 100 provided in this embodiment is as follows: one of the first water inlet hole 111 and the second water inlet hole 112 is used to input cold water, and the other is used to input hot water. Here, the first water inlet hole 111 inputs cold water and the second water inlet hole 112 inputs hot water as an example for explanation: Figure 5 As shown, when the movable member 120 moves to the first preset position relative to the fixed member 110, the first water inlet hole 111 and the second water inlet hole 112 are blocked by the movable member 120, and the mixing valve 100 is in a closed state. When the movable member 120 moves to the second preset position relative to the fixed member 110, the first water inlet hole 111 is connected to the water guide hole 121, and the second water inlet hole 112 is blocked by the movable member 120. The cold water input from the first water inlet hole 111 is guided by the water guide hole 121 and output from the water outlet hole 113. At this time, the mixing valve 100 is in a state of only discharging cold water. Figure 6 As shown, when the movable member 120 moves to the third preset position relative to the fixed member 110, the first water inlet hole 111 and the second water inlet hole 112 are respectively connected to the water guide hole 121. The cold water input by the first water inlet hole 111 and the hot water input by the second water inlet hole 112 are mixed in the water guide hole 121 and then output from the water outlet hole 113 under the guidance of the water guide hole 121. At this time, the mixing valve 100 is in a state of simultaneously outputting hot water and cold water. The water temperature of the output mixed water depends on the ratio of hot water and cold water in the mixed water. The user can adjust it by the faucet handle within the range defined by the third preset position as needed; when the movable member 120 moves to the fourth preset position relative to the fixed member 110, the first water inlet hole 111 is blocked by the movable member 120, the second water inlet hole 112 is connected to the water guide hole 121, and the hot water input by the second water inlet hole 112 is output from the water outlet hole 113 under the guidance of the water guide hole 121. At this time, the mixing valve 100 is in a state of only outputting hot water.

[0046] It can be understood that the mixing valve 100 provided in this embodiment has a first water inlet hole 111, a second water inlet hole 112 and a water outlet hole 113 that are spaced apart from each other in pairs on the fixed member 110, and the first water inlet hole 111 and the second water inlet hole 112 are respectively extended along the circumference of the fixed member 110. On this basis, the movable member 120 is provided with a water guide hole 121 that is connected to the water outlet hole 113, and the hole wall of the water guide hole 121 includes a first curved wall surface 1211, a second curved wall surface 1212, and two first curved wall surfaces 1211 and 1213. A connecting wall 1213 and two second connecting walls 1214, the first curved wall 1211 and the second curved wall 1212 are arranged opposite to each other, the two first connecting walls 1213 are arranged opposite to each other, the two second connecting walls 1214 are arranged opposite to each other, the first curved wall 1211 is connected between the two first connecting walls 1213, the second curved wall 1212 is connected between the two second connecting walls 1214, each first connecting wall 1213 is connected to one second connecting wall 1214, thereby forming Figure 7 Thus, when the user adjusts the handle of the faucet to the middle position, that is, the middle area corresponding to the third preset position (the middle area is Figure 6 The flow rate of the mixed water output by the water outlet 113 is larger, which reduces the difference in water output between the adjustment handle to the middle position and the two end positions, thereby improving the user experience.

[0047] like Figure 2 、 Figure 4 and Figure 7 As shown, in one embodiment, the hole wall of the water guide hole 121 further includes two first inclined walls 1215 disposed opposite to each other, two second inclined walls 1216 disposed opposite to each other, and two third inclined walls 1217 disposed opposite to each other. Each first inclined wall 1215 is connected to the first curved wall 1211 and one second inclined wall 1216, each second inclined wall 1216 is connected to a first connecting wall 1213 and one third inclined wall 1217, and each third inclined wall 1217 is connected to a second connecting wall 1214.

[0048] It is understood that the provision of the first inclined wall 1215, the second inclined wall 1216, and the third inclined wall 1217 can guide the water flow, further reducing the difference in water output between the middle position and the two end positions of the adjustment handle. At the same time, the water flow is made smoother, improving the diversion effect of the water guide hole 121.

[0049] like Figure 2As shown, further, the two first inclined walls 1215 are smoothly connected. It is understandable that by smoothly connecting the two first inclined walls 1215, the resistance of the water flow can be reduced, thereby further improving the diversion effect of the water guide hole 121.

[0050] like Figure 7 As shown, further, each first inclined wall surface 1215 is smoothly connected to the first curved wall surface 1211 and a second inclined wall surface 1216, each second inclined wall surface 1216 is smoothly connected to a first connecting wall surface 1213 and a third inclined wall surface 1217, and each third inclined wall surface 1217 is smoothly connected to a second connecting wall surface 1214. It can be understood that the smooth connection can reduce the resistance of the water flow, thereby further improving the diversion effect of the water guide hole 121.

[0051] like Figure 6 and Figure 8 As shown, in one embodiment, part of the hole wall of the first water inlet hole 111 is recessed in a direction close to the second water inlet hole 112 to form a first arc groove 114, and part of the hole wall of the second water inlet hole 112 is recessed in a direction close to the first water inlet hole 111 to form a second arc groove 115.

[0052] It can be understood that the setting of the first arc groove 114 and the second arc groove 115 can achieve the effect of diversion. At the same time, it increases the flow rate of mixed water output from the water outlet 113 when the user adjusts the handle to the middle position, thereby further reducing the difference in water output between the adjustment handle to the middle position and the two end positions.

[0053] like Figure 2 and Figure 4 As shown, further, the cross-sectional area of ​​the first arc-shaped groove 114 gradually increases in the direction approaching the movable member 120 , and the cross-sectional area of ​​the second arc-shaped groove 115 gradually increases in the direction approaching the movable member 120 .

[0054] It should be noted that the cross-sectional area of ​​the arc-shaped groove refers to the area of ​​the cross section perpendicular to the center line of the fixing member 110 .

[0055] It can be understood that since the cross-sectional area of ​​the first arc-shaped groove 114 gradually increases in the direction approaching the movable part 120, the cross-sectional area of ​​the second arc-shaped groove 115 gradually increases in the direction approaching the movable part 120, that is, the cross-sectional area of ​​the arc-shaped groove gradually changes and gradually increases in the direction approaching the movable part 120, which can further enhance the diversion effect.

[0056] like Figure 1 、 Figure 2 and Figure 8As shown, in one embodiment, the water outlet 113 includes a first hole body 1131 and a second hole body 1132 that are connected to each other. The first hole body 1131 does not penetrate the fixing member 110, and the second hole body 1132 penetrates the fixing member 110. The first hole body 1131 and the second hole body 1132 are respectively connected to the water guide hole 121, and the cross-sectional area of ​​the first hole body 1131 gradually decreases in the direction away from the movable member 120.

[0057] It can be understood that the setting of the first hole body 1131 plays a role in guiding the water flow into the second hole body 1132 for output. Since the first hole body 1131 is set, and the cross-sectional area of ​​the first hole body 1131 gradually decreases in the direction away from the movable part 120, that is, the cross-sectional area of ​​the first hole body 1131 gradually changes and gradually decreases in the direction away from the movable part 120, which further enhances the diversion effect of the first hole body 1131, thereby further reducing the difference in water output between the adjustment handle to the middle position and the two end positions.

[0058] like Figure 2 and Figure 8 As shown, further, the hole wall of the second hole body 1132 includes a third curved wall surface 11321 and a fourth curved wall surface 11322 arranged opposite to each other, and two third connecting wall surfaces 11323 arranged opposite to each other; each third connecting wall surface 11323 is smoothly connected between the third curved wall surface 11321 and the fourth curved wall surface 11322, thereby forming Figure 8 The shape of the second hole 1132 is as shown in FIG. Figure 8 The second hole body 1132 of the shape shown in FIG. 1 is connected to the first hole body 1131 and the Figure 7 The water guide hole 121 of the shape shown is combined to effectively reduce the difference in water output between the middle position and the two end positions of the adjustment handle.

[0059] like Figure 8 As shown, in one embodiment, the first curved wall 1211 is smoothly connected between two first connecting walls 1213 , the second curved wall 1212 is smoothly connected between two second connecting walls 1214 , and each first connecting wall 1213 is smoothly connected to one second connecting wall 1214 .

[0060] It is understandable that the smooth connection can reduce the resistance of the water flow, improve the fluidity of the water flow, and thus increase the water output of the water outlet 113.

[0061] In a second aspect, an embodiment of the present application provides a faucet, comprising a handle, a faucet body, and the mixing valve 100 in any embodiment of the first aspect, wherein the mixing valve 100 is disposed inside the faucet body.

[0062] like Figures 9 to 11As shown, the mixing valve 100 also includes a shell 170, a driving rod 130, a rotating shaft 140, a rod sleeve 150 and a transmission seat 160. The rod sleeve 150 is arranged inside the shell 170 and is sleeved on the driving rod 130. The driving rod 130 is movably arranged in the shell 170 and is hinged to the rod sleeve 150 through the rotating shaft 140. One end of the driving rod 130 is movably connected to the transmission seat 160, and the end of the driving rod 130 away from the transmission seat 160 is connected to the handle. The movable part 120 and the fixed part 110 are arranged inside the shell 170, and the transmission seat 160 is connected to the movable part 120. A first input port 171, a second input port 172 and an output port 173 are provided on the shell 170. The first input port 171 is connected to the first water inlet hole 111, the second input port 172 is connected to the second water inlet hole 112, and the output port 173 is connected to the water outlet hole 113. In this way, the user can use the handle with the help of the driving rod 130 to drive the transmission seat 160 to drive the movable part 120 to fit the fixed part 110 to move, thereby realizing the functions of turning on and off the faucet, adjusting the water temperature, etc., which will not be described in detail here.

[0063] It should be noted that the faucet can be a bathroom faucet, a washbasin faucet, a water purifier faucet, etc., and no specific restriction is made on the type of faucet.

[0064] It should be understood that since the faucet provided in this embodiment has the mixing valve 100 in any embodiment of the first aspect above, it has all the beneficial effects of the mixing valve 100, which will not be described in detail here.
