[0039] Example 1

[0040] See also Figure 1 to Figure 7 The present embodiment provides an energy storage type waterway switching device 10, comprising a valve body 110 and a switching unit 120. The valve body 110 has a water inlet channel 101, a first water outlet channel 102 and a second water outlet channel 103. The switching unit 120 comprises an energy storage component 140 disposed in the valve body 110 and a switching valve core 130 linked to the energy storage component 140. In the process of releasing energy from the energy storage state, the energy storage component 140 drives the switching valve core 130 to move from the first position to the second position. When the switching valve core 130 is in the first position, the water inlet channel 101 is connected to the first water outlet channel 102 through the first valve port 105 of the valve body 110. When the switching valve core 130 is in the second position, the water inlet channel 101 is connected to the second water outlet channel 103 through the second valve port 106 of the valve body 110, thereby realizing the switching water supply to the first water outlet channel 102 and the second water outlet channel 103.

[0041] See also Figure 2The valve body 110 is a split structure, including an inlet valve body 111, a first outlet valve body 112, a second outlet valve body 113 and a main valve body 114. The switching valve core 130 and the energy storage member 140 are arranged in the main valve body 114. The first outlet valve body 112 is sealed and connected to the top of the main valve body 114, and the first outlet channel 102 is arranged in the first outlet valve body 112. The inlet valve body 111 is sealed and connected to one side of the first outlet valve body 112, and the inlet channel 101 is arranged in the inlet valve body 111. The second outlet valve body 113 is arranged on one side of the main valve body 114, and the second outlet channel 103 is arranged in the second outlet valve body 113. The first valve port 105 and the second valve port 106 are formed at the connection between the first outlet valve body 112 and the main valve body 114. Further, the first valve port 105 is arranged directly above the second valve port 106. The water inlet channel 101 and the first water outlet channel 102 are connected through the first valve port 105. The water inlet channel 101 and the second water outlet channel 103 are connected through the second valve port 106.

[0042] Furthermore, in one embodiment, the water inlet valve body 111, the first water outlet valve body 112, the second water outlet valve body 113 and the main valve body 114 can be fixed by plugging, and a sealing ring is provided at the plugging position to achieve sealing fixation. Assembling by plugging is more convenient for assembly and disassembly.

[0043] Specifically, in this embodiment, when the energy storage type waterway switching device 10 starts to take in water from the initial state, the switching valve core 130 is maintained in the first position under the action of water pressure, and the energy storage component 240 is stored. When switching from the water inflow state to the water stop state (about 1 to 2 seconds at the moment of water stop), the energy storage component 140 releases energy to drive the switching valve core 130 to move to the second position. When the switching valve core 130 is in the second position, when switching from the water stop state to the water inflow state, that is, water inflow again after a short water stop, the switching valve core 130 is maintained in the second position under the action of water pressure.

[0044] See also Figure 3When the energy storage waterway switching device 10 is in the initial state without water inflow, the switching valve core 130 remains in the first position, the first valve port 105 is opened, and the second valve port 106 is closed. Specifically, the switching valve core 130 is slidably arranged in the valve body 110, and includes an upper guide portion 131, a blocking portion 132 and a lower guide portion 133. The first valve port 105 and the second valve port 106 are located on both sides of the blocking portion 132, and the blocking portion 132 is used to open or close the first valve port 105 / the second valve port 106. The upper guide 131 is used to introduce the first valve port 105, and the lower guide portion 133 is used to introduce the second valve port 106. Further, the first valve port 105 is arranged above the second valve port 106, a first chamber 134 is arranged in the first water outlet valve body 112, and a second chamber 144 is arranged in the main valve body 114. The upper guide portion 131 is inserted into the first chamber 134, and the lower guide portion 133 is inserted into the second chamber 144. When the switching valve core 130 switches between the first position and the second position, the first chamber 134 and the second chamber 144 provide a guide for the switching valve core 130 to ensure the reliability of the movement of the switching valve core 130.

[0045] Furthermore, the energy storage member 140 includes an elastic member 141 and a piston member 142. The piston member 142 is movably disposed in an active cavity 143. The active cavity 143 is provided with a water inlet end connected to the water inlet channel 101. The elastic member 141 is disposed between the piston member 142 and the switching valve core 130. When water enters the water inlet channel 101, the piston member 142 presses the elastic member 141 upward under the action of water pressure, so that the elastic member 141 stores energy.

[0046] Furthermore, the elastic member 141 is configured as a spring, and the spring is configured in the second chamber 144. The ends of the switching valve core 130 and the piston member 142 are respectively inserted into the two ends of the second chamber 144, so that the two ends of the spring are respectively in contact with the switching valve core 130 and the piston member 142. When water enters the water inlet channel 101, the switching valve core 130 above the second chamber 144 is subjected to the downward force applied by the water pressure and remains motionless. At the same time, the movable chamber 143 below the second chamber 144 enters water, and the piston member 142 moves upward under the action of the water pressure, thereby compressing the spring and completing the energy storage of the energy storage member 140.

[0047] It should be noted that, in other embodiments, the elastic member 141 may also be configured as an airbag, an elastic rubber block or other structure with energy storage function.

[0048] Further, the piston member 142 includes a piston 145 and a return spring 146. Further, a sealing ring 147 is provided on the circumferential side of the piston 145, and the sealing ring 147 contacts the side wall of the active chamber 143. The active chamber 143 is divided into an upper chamber 150 and a lower chamber 151 by the cooperation of the sealing ring 147 and the piston 145, and the lower chamber 151 is connected to the water inlet end of the active chamber 143, that is, connected to the water inlet channel 101. When the water flow of the water inlet channel 101 enters the lower chamber 151, the water pressure drives the piston 145 to move upward, completing the energy storage of the elastic member 141. A water inlet hole 107 is provided on the top of the active chamber 143, and the water inlet hole 107 is located below the second valve port 106 and is connected to the second water outlet channel 103. When the second valve port 106 is opened, water flows into the upper chamber 150 of the movable chamber 143 through the water inlet hole 107 , exerting downward water pressure on the piston 145 , driving the piston 145 to move downward, thereby achieving rapid resetting of the piston 145 .

[0049] The return spring 146 is arranged on the side of the piston 145 away from the lower chamber 151. When the piston 145 moves upward under the action of water pressure, the return spring 146 is compressed. When the water pressure on the piston member 142 is eliminated, the return spring 146 is reset, driving the piston 145 to move downward, completing the reset of the piston member 142. During the reset process of the piston member 142, the elastic member 141 rebounds to release energy.

[0050] Furthermore, the bottom surface of the piston 145 extends downward to form a guide rod 148. A fourth chamber 149 is provided in the main valve body 114. The guide rod 148 moves up and down along the fourth chamber 149. The fourth chamber 149 provides a guiding function for the guide rod 148 to ensure the reliability of the movement of the guide rod 148.

[0051] Furthermore, the present embodiment also provides a toilet, including a toilet body and the above-mentioned energy storage water circuit switching device 10, the toilet body having a brush ring water circuit and a main flushing water circuit, the first water outlet channel 102 is connected to the brush ring water circuit, and is used to flush the inner wall surface of the toilet bowl, and the second water outlet channel 103 is connected to the main flushing water circuit, and is used to flush the toilet sewage outlet.

[0052] The working process of the energy storage waterway switching device 10 of this embodiment is as follows:

[0053] like Figure 3 As shown, the energy storage waterway switching device 10 is in an initial state, the water inlet channel 101 is not opened, the switching valve core 130 is in the first position, the first valve port 105 is open, and the second valve port 106 is closed.

[0054] like Figure 4As shown, the water inlet channel 101 is opened to inlet water, forming two water flows. One water flow enters the first water outlet channel 102 through the first valve port 105, drives the brush ring water channel to discharge water, and applies downward water pressure to the switching valve core 130, so that the switching valve core 130 remains stationary. The other water flow enters the active chamber 143, and the piston 142 moves upward under the action of water pressure, compressing the elastic member 141 and the reset spring 146, so as to store energy in the elastic member 141. The elastic force of the elastic member 141 to reset is less than the water pressure on the switching valve core 130, and the water discharge state of the brush ring water channel is maintained.

[0055] like Figure 5 As shown, the water inlet channel 101 is closed to inlet water. At the moment of water cut-off (about 1 to 2 seconds), the water pressure on the switching valve core 130 is eliminated, and the stored energy of the elastic member 141 is released, pushing the switching valve core 130 to move upward to the second position, the second valve port 106 is opened, and the first valve port 105 is closed or partially closed. At the same time, the piston member 142 is slowly reset under the action of gravity and the reset spring 146.

[0056] like Figure 6 As shown, water enters the water inlet channel 101 again, and the water flows into the second water outlet channel 103 through the second valve port 106, driving the water out of the main flushing water path. At this time, the switching valve core 130 is kept in the second position under the action of water pressure, maintaining the water outflow state of the main flushing water path. At the same time, water flows into the upper chamber of the third chamber 150 from the water inlet hole 107, and the piston member 142 is quickly reset under the action of water pressure. After the main flushing is completed, the water inlet channel 101 stops flowing, and the switching valve core 130 falls to the first position under the action of gravity, returning to the initial state.

[0057] Example 2

[0058] See also Figures 7 to 11 This embodiment provides an energy storage type water channel switching device 20, and its implementation principle is roughly the same as that of embodiment 1. For parts not described in detail, please refer to the contents of embodiment 1.

[0059] In this embodiment, the energy storage type waterway switching device 20 includes a valve body 210 and a switching unit 220. The valve body 210 has a water inlet channel 201, a first water outlet channel 202 and a second water outlet channel 203. The switching unit 220 includes an energy storage component 240 disposed in the valve body 210 and a switching valve core 230 linked to the energy storage component 240. When the energy storage component 240 releases energy from the energy storage state, it drives the switching valve core 230 to move from the first position to the second position. When the switching valve core 230 is in the first position, the water inlet channel 201 is connected to the first water outlet channel 202 through the first valve port 205 of the valve body 210. When the switching valve core 230 is in the second position, the water inlet channel 201 is connected to the second water outlet channel 203 through the second valve port 206 of the valve body 210, thereby realizing the switching water supply to the first water outlet channel 202 and the second water outlet channel 203.

[0060] Further, in this embodiment, the water inlet channel 201 is located on one side of the switching valve core 230, the first water outlet channel 202 and the second water outlet channel 203 are located on the other side of the switching valve core 230, and the first water outlet channel 102 is located above the second water outlet channel 103. The energy storage member 240 is disposed below the switching valve core 230 to drive the switching valve core 230 to move upward.

[0061] In this embodiment, the switching valve core 230 includes a deformable member 233 having a deformable structure. In the initial state where no water enters the water inlet channel 201, the deformable member 233 of the switching valve core 230 does not deform, and its top closes the first valve port 205, and its bottom closes the second valve port 206. When the switching valve core 230 is subjected to downward pressure, the deformable member 233 deforms to open the first valve port 205, and at this time, the switching valve core 230 is located in the first position. When the switching valve core 230 is subjected to upward pressure, it moves upward to open the second valve port 206, and at this time, the switching valve core 230 is located in the second position.

[0062] Further, in this embodiment, the switching valve core 230 includes an upper valve core 231, a lower valve core 232, and a deformable member 233 disposed between the upper valve core 231 and the lower valve core 232. The deformable member 233, the upper valve core 231, and the lower valve core 232 enclose a pressure chamber 208, and the lower valve core 232 is provided with a through hole 238. In the initial state, the upper valve core 231 is used to close the first valve port 205, and the lower valve core 232 closes the second valve port 206. When the switching valve core 230 is in the first position, the upper valve core 231 opens the first valve port 205, and when the switching valve core 230 is in the second position, the lower valve core 232 opens the second valve port 206. Further, when the water inlet channel 201 starts to inlet water from the initial state, the water pressure drives the upper valve core 231 to move downward, driving the deformable member 233 to deform in the direction of the lower valve core 232, so that the first valve port 205 is opened. At the same time, the air in the pressure chamber 208 is discharged through the through hole 238, and the energy storage member 240 is in a compressed energy storage state. When the water inlet channel 201 stops water, the energy storage member 240 releases energy, drives the lower valve core 232 to move upward, drives the deformable member 233 to deform in the direction of the upper valve core 231, and the lower valve core 232 opens the second valve port 206. At the same time, the outside air or water enters the pressure chamber 238 through the through hole 208. When the water inlet channel 201 is filled with water again, the water pressure of the water inlet keeps the lower valve core 232 in the state of opening the second valve port 206.

[0063] Specifically, in this embodiment, the area of ​​the upper valve core 231 receiving water pressure is smaller than the area of ​​the lower valve core 232 receiving water pressure. When water is introduced again, the forces acting on the switching valve core 230 include: the upward water pressure F1 exerted by the water inlet channel 201 on the lower valve core 232, the downward water pressure F2 exerted by the pressure chamber 238 on the lower valve core 232, the downward water pressure F3 exerted by the water inlet channel 201 on the upper valve core 231, and the downward deformation force F4 exerted by the deformation member 233 on the lower valve core 232 when it is reset, satisfying: F1>F2+F3+F4, so as to ensure that the lower valve core 232 remains in the state of opening the second valve port 206.

[0064] It is understandable that the force on the switching valve core 230 can be regulated by adjusting the pressure areas of the upper valve core 231 and the lower valve core 232, the deformation capacity of the deformable part 233, etc., to ensure that when water is entering again, the second valve port 206 remains open and water is maintained out of the second channel 203.

[0065] Specifically, the upper valve core 231 is connected to the deformable member 233 through a pin 234, and the deformable member 233 is configured as a silicone pad. The silicone pad has a plurality of annular steps on its circumference, which can be deformed in the vertical direction to change the height of the switching valve core 230, thereby opening the first valve port 205 or the second valve port 206. A plug-in connector 235 is also provided between the deformable member 233 and the lower valve core 232, and the upper end of the plug-in connector 235 passes through the deformable member 233 and is plugged into the upper valve core 231, and the lower end is plugged into the lower valve core 232.

[0066] Further, in this embodiment, the energy storage member 240 is configured as an elastic member 241, and the two ends of the elastic member 241 are respectively in contact with the lower valve core 232 and the bottom wall of the valve body 210. In the initial state where no water enters the water inlet channel 201, the energy storage member 240 is in a compressed state to maintain an energy storage state, so that at the moment of water cut-off, the water pressure acting on the upper valve core 231 is eliminated, and the elastic member 241 rebounds to release energy, which can apply an upward driving force to the switching valve core 230 to open the second valve port 206.

[0067] Specifically, the bottom of the lower valve core 232 extends downward to form a positioning rod 236, and the elastic member 241 is a spring, which is sleeved outside the positioning rod 236. Further, the valve body 210 is provided with a receiving chamber 207, and the spring is placed in the receiving chamber 207. The spring is limited by the positioning rod 236 and the receiving chamber 207 to ensure that the spring applies an upward elastic force to the switching valve core 230.

[0068] Furthermore, a reset spring 237 is also provided between the upper valve core 231 and the lower valve core 232, and the reset spring 237 is used to reset the upper valve core 231 or the lower valve core 232 to the initial state, that is, to reset to the state where the switching valve core 230 is not deformed. It is understandable that in other embodiments, the switching valve core can also be configured as an airbag (not shown), and in the initial state, the two ends of the airbag close the first valve port 205 and the second valve port 206, and when the water inlet channel 201 is filled with water, the airbag is compressed and deformed to open the first valve port 205. The energy storage member 240 is configured as an elastic member (such as a spring), and in the initial state, the elastic member is in a compressed state. When the water inlet channel 201 is filled with water, the upper end of the airbag is compressed, and the first valve port 205 is opened, so as to realize the connection between the water inlet channel 201 and the first water outlet channel 202. When the water inlet channel 201 stops water, the energy storage member 240 releases energy to drive the airbag to move to open the second valve port 206. The water inlet channel 201 and the second water outlet channel 203 are connected. When the water inlet channel 202 stops flowing, the airbag can be reset. The principle of the switching valve core is basically the same as the switching valve core 230 described above, and will not be repeated here.

[0069] The working process of the energy storage waterway switching device 10 of this embodiment is as follows:

[0070] like Figure 8 As shown, the energy storage waterway switching device 20 is in the initial state, the water inlet channel 201 is not opened, the upper valve core 231 of the switching valve core 230 closes the first valve port 205, and the lower valve core 232 closes the second valve port 206. The elastic member 241 is in a compressed state, that is, an energy storage state.

[0071] like Fig. 9 As shown, the water inlet channel 201 is opened to let in water, and the water flow exerts downward pressure on the switching valve core 230. Under the action of the water pressure, the deformable member 233 of the switching valve core 230 is deformed to open the first valve port 205. The water flows into the first water outlet channel 202 through the first valve port 205, driving the brush ring water channel to discharge water. At the same time, the water pressure on the switching valve core 230 is greater than the elastic force of the elastic member 241, maintaining the water discharge state of the brush ring water channel.

[0072] like Fig.10 As shown, the water inlet channel 201 closes the water inlet. At the moment of water cut-off (approximately 1 to 2 seconds), the water pressure on the switching valve core 230 is released, and the energy stored in the elastic member 141 is released, pushing the switching valve core 230 to move upward as a whole, the second valve port 206 is opened, and the first valve port 205 is closed or partially closed.

[0073] like Fig.11 As shown, water enters the water inlet channel 201 again, and the water flows into the second water outlet channel 203 through the second valve port 206, driving the main flushing water path to discharge water. At this time, the switching valve core 230 keeps the first valve port 205 closed and the second valve port 206 open under the action of water pressure, maintaining the water discharge state of the main flushing water path. After the main flushing is completed, the water inlet channel 201 stops flowing, and the switching valve core 230 returns to the initial state under the action of the reset spring 237.
