DETAILED DESCRIPTION
[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0035] The utility model relates to a water diverter valve, comprising a valve seat 100 , a valve core 200 and a valve stem assembly 300 .
[0036] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the valve seat 100 is provided with an inlet channel 110, a plurality of outlet channels 120 and a water outlet cavity 130. The inlet channel 110 and each outlet channel 120 are connected to the water outlet cavity 130. Two, three or more outlet channels 120 can be provided. In the present embodiment, three outlet channels 120 are provided on the valve seat 100, and the water outlet cavity 130 has an opening upward except for the position connected to the inlet channel 110 and each outlet channel 120. The valve core 200 is installed in the water outlet cavity 130 from the opening, and is mainly used to control the opening and closing between each outlet channel 120 and the inlet channel 110. The valve core 200 is provided with a plurality of water passages 210, guide channels 220 and pressure relief channels 230. The number of water passages 210 is consistent with the number of outlet channels 120. Each water passage 210 is paired with each water outlet channel 120, and one water passage 210 is correspondingly connected to one water outlet channel 120, and each water outlet channel 120 can be connected to the water inlet channel 110 through the corresponding water passage 210. The water passage 210 is paired with the guide channel 220 one by one. The number of valve stem assemblies 300 is consistent with the number of water outlet channels 120. Each valve stem assembly 300 is movably mounted on the valve core 200, and each valve stem assembly 300 is axially movable on the valve core 200. Each valve stem assembly 300 is paired with each water passage 210 one by one, and one valve stem assembly 300 is correspondingly penetrated in one water passage 210. When the valve stem assembly 300 moves, it has a water-passing position in which the water passage 210 is opened and a water-cutting position in which the water passage 210 is closed. One end of the valve stem assembly 300 passes through the water passage 210 and is inserted into the guide channel 220. When the valve stem assembly 300 moves, the end of the valve stem assembly 300 moves in the guide channel 220. A sealing ring can be installed at the end of the valve stem assembly 300, and the end of the valve stem assembly 300 and the guide channel 220 are in sealed sliding connection. Each guide channel 220 is connected to the pressure relief channel 230. The pressure relief channel 230 is connected to the outside atmosphere. The sealed sliding connection between the end of the valve stem assembly 300 and the guide channel 220 can prevent the water in the water outlet cavity 130 from being discharged through the guide channel 220 and the pressure relief channel 230. One end of the valve stem assembly 300 extends to the outside of the valve seat 100, and the axial translation of the valve stem assembly 300 can be achieved by pressing.
[0037] When in use, the water diverter valve is applied to the water outlet device, which may be a shower head, a toilet and other products. The following water outlet device is described using a shower head as an example. The water inlet channel 110 is connected to a water supply system such as a water heater, a water pipe and the like. Each water outlet channel 120 can be connected to different nozzles of the shower head through different water pipes. Each valve stem assembly 300 is used to control the opening and closing of the corresponding water passage 210, so that water can be sprayed out from different water outlet channels 120 for use. When a valve stem assembly 300 moves from the water-off position to the water-on position, the end of the valve stem assembly 300 extends into the interior of the corresponding guide channel 220, and the air in the guide channel 220 is discharged to the pressure relief channel 230, so that the guide channel 220 and the pressure relief channel 230 can maintain a balanced and stable state with the external atmospheric pressure. When the valve stem assembly 300 moves from the water-passing position to the water-blocking position, the end of the valve stem assembly 300 moves in the inner direction away from the corresponding guide channel 220, and the guide channel 220 inhales the outside air through the pressure relief channel 230, so that the guide channel 220 and the pressure relief channel 230 can maintain a balance and stability with the outside atmospheric pressure. During the movement of the valve stem assembly 300, the guide channel 220 and the pressure relief channel 230 maintain a balance with the outside air pressure, thereby reducing the switching force required to control the movement of each valve stem assembly 300, achieving a good labor-saving effect, and during the movement of the valve stem assembly 300, there will be no pressure rebound inside the valve core 200, which can well protect the internal components of the valve core 200 and ensure the service life of the product.
[0038] In some embodiments of the present invention, Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the valve core 200 includes a valve body 240. The valve body 240 can also be assembled by multiple components. Among them, the valve body 240 is divided into multiple water passage chambers 241. The number of water passage chambers 241 is consistent with the number of water outlet channels 120. Each water passage chamber 241 is connected to the water inlet channel 110. In this embodiment, one of the through openings of the water passage chamber 241 is opened on the side wall of the valve core 200. The valve core 200 is installed in the water outlet chamber 130, and there may be a certain gap between the side wall of the valve core 200 and the water outlet chamber 130. A sealing ring is provided between the top of the valve core 200 and the water outlet chamber 130 for sealing. The water inlet channel 110 conducts water to each water passage chamber 241 through the gap. The water passage 210, the guide channel 220 and the pressure relief channel 230 can all be arranged in the valve body 240. The water passage 210 has a first end 211 and a second end 212. The first end 211 can extend into the water passage cavity 241, and the water passage channel 210 is connected to the water passage cavity 241 through the first end 211. The second end 212 is connected to the water outlet channel 120. Figure 6 and Figure 7As shown, the water passage 210 may be in an inverted U shape, the second end 212 of each water passage 210 may be arranged on the bottom end surface of the valve body 240, and one end of each water outlet flow channel 120 may extend to the bottom of the water outlet chamber 130. The bottom of the valve body 240 is pressed down onto the water outlet chamber 130, and the two are sealed and butted by a sealing ring. The guide channel 220 extends into the water passage chamber 241. The first end 211 and one end of the guide channel 220 are opposite in the water passage chamber 241. In the direction shown in the figure, the first end 211 is located above the guide channel 220. The valve stem assembly 300 penetrates into the valve body 240 from top to bottom, the lower part of the valve stem assembly 300 penetrates into the water passage 210 and passes downward from the first end 211, and the lower end of the valve stem assembly 300 is sleeved with a sealing ring and inserted into the guide channel 220. When the valve stem assembly 300 moves axially up and down, it can control the opening and closing of the first end 211, thereby controlling whether water flows through the water passage 210. When the valve stem assembly 300 moves downward, the first end 211 is opened to allow water to flow through the water passage 210, and when the valve stem assembly 300 moves upward, the first end 211 is closed to cut off water flow through the water passage 210.
[0039] Further, such as Figure 5 As shown, the valve core 200 also includes a valve plate 250. A spherical protrusion 251 is provided at the center of the valve plate 250, and a spherical depression can be provided on the top surface of the valve body 240. The valve plate 250 realizes a ball hinge by cooperating between the spherical protrusion 251 and the spherical depression on the top surface of the valve body 240. The valve plate 250 can swing relative to the valve body 240 with the spherical protrusion 251 as a support. The valve stem assemblies 300 are parallel to each other and are evenly spaced around the spherical protrusion 251 and are penetrated through the valve plate 250 and the valve core 200. In the present embodiment, three valve stem assemblies 300 are provided, and correspondingly, three notches are opened on the valve plate 250 at equal intervals along the circumferential direction. One notch is correspondingly penetrated for one valve stem assembly 300. As shown Figure 5 and Figure 6 As shown, when one of the valve stem assemblies 300 moves downward, the water passage 210 corresponding to the valve stem assembly 300 opens to allow water to flow, and at the same time, the corresponding position of the valve plate 250 is pressed down, with the spherical protrusion 251 as a rotation support, and the other positions of the valve plate 250 tilt upward, driving the other valve stem assemblies 300 to move upward and close the other water passages 210. Press one of the valve stem assemblies 300, and use the tilting action of the valve plate 250 to move the other valve stem assemblies 300 in the opposite direction, so that only one water passage 210 and water outlet channel 120 can discharge water at a time. During the switching process, the cooperation of the guide channel 220 and the pressure relief channel 230 can effectively reduce the external force required for shifting, and the switching operation is very convenient and labor-saving.
[0040] In some specific embodiments of the present invention, Figure 4 and Figure 5As shown, a plurality of air release channels 231 are provided on the bottom end surface of the valve core 200. One end of each guide channel 220 extends to the bottom end surface of the valve core 200 and is connected to each air release channel 231 one by one. A converging air channel 232 is provided inside the valve core 200, and the converging air channel 232 can extend upward from the bottom end surface of the valve core 200 along the axial direction of the valve core 200, and extend to the ball hinge between the valve core 200 and the spherical protrusion 251. The spherical protrusion 251 is provided with a through hole 252, and the through hole 252 is kept in communication with the converging air channel 232 during the tilting process of the valve plate 250 relative to the valve body 240. Each air release channel 231 is connected to the converging air channel 232. Each air release channel 231 and the converging air channel 232 constitute a pressure relief channel 230. Each guide channel 220 is connected to the external air pressure through the corresponding air leakage channel 231 , the converging air channel 232 and the through hole 252 of the spherical protrusion 251 .
[0041] Among them, Figure 5 and Figure 6 As shown, an elastic member 400 is connected to one of the valve stem assemblies 300, and the elastic member 400 can be a member that can be elastically deformed, such as a spring, a spring sheet, etc. In this embodiment, the elastic member 400 is a spring, which is sleeved on the valve stem assembly 300, one end of the spring can abut against the valve body 240, and the other end acts on the valve stem assembly 300. The elastic member 400 has an elastic force on the valve stem assembly 300, and the elastic force drives the valve stem assembly 300 to move in the direction of opening the corresponding first end 211. In the direction shown in the figure, the elastic member 400 applies a downward elastic force to the valve stem assembly 300, so that the corresponding first end 211 of the valve stem assembly 300 is opened. When the valve stem assembly 300 provided with the elastic member 400 closes the corresponding first end 211, the elastic member 400 is elastically compressed, and the corresponding water passage chamber 241 is filled with water, so that the valve stem assembly 300 is kept in the position of closing the first end 211 under the action of water pressure. When the external water supply system stops supplying water to the water inlet channel 110, the valve stem assembly 300 provided with the elastic member 400 automatically returns to the position corresponding to the first end 211 under the elastic force. Figure 7 As shown, the other valve stem assemblies 300 close the corresponding first ends 211. Only one elastic member 400 is needed to realize the automatic reset of each valve stem assembly 300 after water is cut off. The reset process does not require long pressing of the valve stem assembly 300, and with the pressure relief function of the pressure relief channel 230, the reset process of each valve stem assembly 300 is very smooth and fast.
[0042] Further, such as Figure 6 and Figure 7As shown, the valve stem assembly 300 is provided with a convex disc 301. The convex disc 301 moves up and down with the axial movement of the valve stem assembly 300. When the valve stem assembly 300 moves upward, the upper side of the convex disc 301 can abut against the first end 211 and block the first end 211. The water in the water passage chamber 241 acts on the convex disc 301, and the convex disc 301 stably closes the first end 211 under the action of water pressure. When the valve stem assembly 300 moves downward, the lower side of the convex disc 301 abuts against the end of the guide channel 220, thereby limiting the downward movement of the valve stem assembly 300.
[0043] The specific structure of the valve stem assembly 300 is not limited, and the opening and closing of the flow passage can be controlled by the stem structure relative to the axial direction of the valve core 200. Figure 7 , Figure 8 and Figure 7 As shown, the valve stem assembly 300 includes a button 310, a connector 320 and a rod 330. The connector 320 may be a columnar structure, and the interior of the connector 320 is hollow to form a first plug-in cavity 321, and the first plug-in cavity 321 is open. The upper end of the connector 320 is connected to the button 310, and the two can be connected by plugging, clamping or screw locking. The rod 330 is movably mounted on the valve core 200, and one end of the rod 330 is inserted and clamped in the first plug-in cavity 321. The button 310 and the rod 330 are connected by the connector 320, so that different buttons 310 and rods 330 are adapted. The user controls the movement of the valve stem assembly 300 by pressing the button 310, and the valve plate 250 can be abutted against each other by the connector 320 during movement to realize the linkage of the valve stem assembly 300 and the valve plate 250.
[0044] Specifically, the side wall of the connector 320 is provided with an opening 322 connected to the first plug-in cavity 321. Two openings 322 can be provided. A clamping column 323 extending along the plug-in direction of the rod 330 is provided in the opening 322. The clamping column 323 extends upward from the lower side of the opening 322, and the upper end of the clamping column 323 is spaced apart from the upper side wall of the opening 322. A barb 331 is provided at the upper end of the rod 330. After the upper end of the rod 330 is inserted into the first plug-in cavity 321, the barb 331 is clamped in the space formed by the end of the clamping column 323 and the side wall of the opening 322, thereby realizing the clamping of the connector 320 and the rod 330. Among them, the second plug-in cavity 311 can be provided on the button 310. After the rod 330 and the connector 320 are assembled, the connector 320 is plugged into the second plug-in cavity 311, and the clamping column 323 also enters the second plug-in cavity 311. The inner wall of the second inserting cavity 311 limits the clamping column 323 from swinging radially outward relative to the first inserting cavity 321 , that is, the barb 331 is stably clamped in the distance between the clamping column 323 and the opening 322 .
