Abstract
Description
Technical Field
[0001] This utility model relates to an instant-triggered water valve control mechanism. Background Technology
[0002] A flush valve, also known as a flushing valve, is a key actuator in sanitary ware (such as toilets and urinals) used to control water flow and achieve the flushing function. Its core function is to release a fixed amount of water within a specific time after receiving a trigger signal to complete the flushing and then automatically shut off.
[0003] Existing technologies, such as the tankless mechanical valve flushing system described in patent CN114411898B, use a delay setting in the activation chamber to allow a single trigger to control the main control piston to complete a reciprocating motion. During this process, the main control piston controls the water path switching mechanism to switch the outlet pipe, thereby driving the water flow to complete the entire process of outer ring flushing, jet flushing, and outer ring secondary flushing and water storage. This flushing valve requires a prolonged pressing of the button to ensure smooth and normal drainage, affecting the user experience. Therefore, to address the above problems, this utility model designs an instant-trigger water valve control mechanism. Utility Model Content An instant-triggered water valve control mechanism includes a water valve body having an inlet and at least one outlet, and a pilot valve disposed between the inlet and the outlet, and further includes: The delay valve has a delay valve chamber with a connecting inlet. A pressure relief component is provided above the delay valve chamber. A sliding piston is provided inside the delay valve chamber. A locking component is provided inside the delay valve chamber. Its structure is such that after the pressure relief component is activated, it is locked. When the pressure is released in the delay valve chamber, the sliding piston slides to the top of the locking component and unlocks the pressure relief component, so that the delay valve chamber closes and releases pressure, and the sliding piston returns to its original position. The starting unit is configured such that when the sliding piston is reset, the linked sliding piston opens the pilot valve.
[0004] The beneficial effects of this utility model are as follows: A pressure relief valve switch is provided in the delay valve chamber and a locking component is provided. The structure is such that after the pressure relief component is activated, it is locked, so that the system is always in a pressure relief state. The pressure relief in the delay valve chamber causes the sliding piston to slide to the top of the locking component and unlock the pressure relief component, thereby closing the pressure relief component and resetting the sliding piston. When the sliding piston is reset, the starting unit linked to the sliding piston opens the pilot valve, thereby opening the water circuit. The advantage of this structure is that the delay valve can be put into a pressure relief state by pressing and releasing the pressure relief component instantly, so as to complete the subsequent flushing action. There is no need for the user to press for a long time, which can improve the user experience. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Reference Figures 1-3As shown, an instant-triggered water valve control mechanism includes a water valve body 10 with an inlet and at least one outlet, and a pilot valve 20 disposed between the inlet and the outlet. It also includes a delay valve 30 with a delay valve chamber 31 communicating with the inlet. A pressure relief assembly 32 is disposed above the delay valve chamber 31. A sliding piston 33 is disposed within the delay valve chamber 31, and a locking member 37 is disposed within the delay valve chamber 31. The mechanism is configured such that after the pressure relief assembly 32 is activated, it is locked. Pressure relief within the delay valve chamber 31 causes the sliding piston 33 to slide to the top of the locking member 37, unlocking the pressure relief assembly 32. This closes the pressure relief in the delay valve chamber 31, and the sliding piston 33 resets. A momentary press and release of the pressure relief assembly puts the delay valve in a pressure-relieved state, allowing subsequent flushing actions to be completed without requiring prolonged pressing by the user, thus improving the user experience. The activation unit is configured such that when the sliding piston 33 resets, it triggers the sliding piston 33 to open the pilot valve 20. In one embodiment, the water valve body 10 has an inlet pipe 11, and a first outlet pipe 12 and a second outlet pipe 13 connected to the inlet pipe 11. The inlet pipe 11 has an inlet, the first outlet pipe 12 has a first outlet, and the second outlet pipe 13 has a second outlet. A plug 15 is provided at the end of the inlet pipe 11. An anti-siphon block 16 is installed at the connection between the first outlet pipe 12, the second outlet pipe 13, and the inlet pipe 11. The inlet pipe 11 has a pilot valve 20 for opening / closing the flow channel of the inlet pipe 11 and a switching valve 50 for switching the flow channel. The switching valve 50 can switch the water flow in the inlet pipe 11 to the first outlet pipe 12 or the second outlet pipe 13. In this embodiment, the first outlet pipe 12 is connected to the flushing assembly in the toilet, and the second outlet pipe 13 is connected to the flushing assembly in the toilet. The second outlet pipe 13 acts as a flushing aid, forming a siphon effect to flush away the excrement.
[0025] The sliding piston 33 divides the delay valve chamber 31 into an inner chamber 311 and an outer chamber 312. The sliding piston 33 has a water passage hole 331 that connects the inner chamber 311 and the outer chamber 312. When the pressure relief assembly 32 is opened, water flows into the outer chamber 312 and pushes the sliding piston 33 to move to the other side of the delay valve chamber 31. The pilot valve 20 is in the closed state, and the one-way starting mechanism 40 does not act on the pilot valve 20. The pressure relief assembly 32 is closed, allowing water in the outer chamber 312 to enter the inner chamber through the water passage hole 331. Within 311, the sliding piston 33 is reset, and the one-way starting mechanism 40 then opens the pilot valve 20, thereby opening the water passage of the water valve body 10. In this utility model, the water pressure in the main pipeline first acts on the delay valve 30, concentrating the water pressure that pushes the sliding piston group, and then drives the one-way starting mechanism 40 to open the pilot valve 20 by pushing the sliding piston 33. Then, the principle of driving a large water pressure with a small water pressure in the pilot valve 20 is utilized. This structural design can be started under low pressure conditions, without needing to increase the diameter of the delay valve piston to achieve a large drive, which can save the space used by the flush valve.
[0026] This utility model also includes a water path switching mechanism 60, which includes a rocker assembly for controlling the switching valve 50 to switch the water outlet path and a control plate assembly. The control plate assembly includes a slide plate 63 that moves synchronously with the piston, and a control plate 64 that is detachably installed in the slide plate 63. The control plate 64 is provided with a control groove 641. The control groove 641 is configured to accommodate the rocker assembly to slide inside it during the piston movement, thereby switching the water outlet path and controlling the water outlet duration. By providing a detachable control plate 64, control plates 64 of different specifications can be replaced. The flushing time of similar products on the market is not adjustable. The control plate 64 of this utility model can be designed with control grooves 641 with different flushing durations according to customer needs.
[0027] This utility model has multiple delay valves 30, and the water passage grooves 331 of the sliding piston assemblies in the multiple delay valves 30 are of different sizes; the delay valve switching component 70 is configured to switch the single delay valve 30 when a single delay valve 30 is activated, thereby controlling the one-way starting mechanism 40 to open the pilot valve 20. By setting water passage grooves 331 of different sizes, the time for water to enter the delay valve chamber 31 is affected, thereby controlling the total flushing time of the flushing valve, triggering the switches on different delay valves 30, and switching the flushing control through the delay valve switching component 70, which can achieve large discharge and / or small discharge effects.
[0028] The structure of each component of this utility model will be described below.
[0029] First, the structure of the delay valve 30 and its working principle in this embodiment will be explained in detail: Reference Figures 1-4As shown, the pressure relief assembly 32 includes a pressure relief rod seat 321 disposed on the top of the delay valve chamber 31. A pressure relief hole 3211 is disposed above the pressure relief rod seat 3211. A slidable pressure relief actuating rod 322 is installed in the pressure relief hole 3211. The pressure relief actuating rod 322 presses against the pressure relief switch 36. A sealing part 3221 is disposed on the pressure relief actuating rod 322, which seals the pressure relief hole 3211. A second spring 323 is pressed against the bottom of the sealing part 3221. The locking member 37 is disposed at the bottom of the pressure relief rod seat 321, and the other end of the second spring 323 presses against the locking member 37. The locking member 37 has a through hole 371 along its axial direction. An annular locking block 372 is located at the bottom of the through hole 371. A receiving groove 3222 corresponding to the annular locking block 372 is located at the end of the pressure relief starting rod 322. An annular boss 373 extends downward from the bottom of the locking member 37. An annular groove 374 is inclinedly located in the middle of the annular boss 373. A pressing block 332 corresponding to the annular groove 374 is located in the middle of the upper end of the sliding piston 33. The sliding piston 33 presses against the first spring 34 above it. The other end of the first spring 34 presses against the pressure relief rod seat 321. A piston rod 35 is connected below the plug 33. Pressing the pressure relief switch 36 causes the pressure relief activation rod 322 to descend and compress the second spring 323. The sealing part 3221 separates from the pressure relief hole 3211. The annular locking block 372 is placed in the receiving groove 3222 to lock and fix the pressure relief activation rod 322, keeping the system in a pressure-relieved state. The pressure relief valve chamber releases pressure, causing the sliding piston 33 to compress the first spring 34 and move upward. The top pressure block 332 pushes the annular groove 374 upward, causing the annular locking block 372 to disengage from the receiving groove 3222. The second spring 323 resets and pushes the pressure relief activation rod 322 upward, sealing... The plug 3221 blocks the pressure relief hole 3211. In this embodiment, the locking member 37 is made of a material with a certain elastic limit, such as thermoplastic polyurethane. It allows the pressure relief start rod 322 to move through the guide hole 371, so that the annular locking block 372 is set in the receiving groove 3222. It can also increase the opening size of the annular locking block 372 when the sliding piston 33 presses against the annular groove 374, so that the annular locking block 372 is disengaged from the receiving groove 3222. This structure allows the user to press the pressure relief switch 36 briefly to start the delay valve 30 for flushing without waiting, thus improving the user experience.
[0030] The structure and working principle of the pilot valve 20 in this embodiment are described in detail below: (Refer to...) Figure 1 , Figure 2 , Figure 5As shown, the inlet pipe 11 has an inlet chamber 111 and an opening / closing chamber 112. The pilot valve 20 includes an elastic diaphragm 21 disposed above the opening / closing chamber 112. The elastic diaphragm 21 has a certain elastic limit and isolates the inlet chamber 111 and the opening / closing chamber 112. A pilot valve plate 22 is disposed above the elastic diaphragm 21. A first through hole 221 is provided on the bottom wall of the pilot valve plate 22, and a second through hole 222 is provided on the bottom wall of the middle part of the pilot valve plate 22. A pressure relief chamber 23 is disposed above the pilot valve plate 22. Water chamber 111 is connected to pressure relief chamber 23 through first through hole 221. A pilot valve 20 activation assembly is installed in pressure relief chamber 23. The pilot valve 20 activation assembly includes a pilot valve control rod 24 installed in pressure relief chamber 23. One end of the pilot valve control rod 24 passes through pressure relief chamber 23 and is positioned above it. The other end of the pilot valve control rod 24 is connected to an opening / closing block 25. The opening / closing block 25 blocks the second through hole 222 and presses against a third spring 26. The other end of the third spring 26 presses against the top wall of pressure relief chamber 23, thus lifting the pilot valve control rod. Rod 24 and the opening / closing stop 25 separate from the second through hole 222. Water in the inlet chamber 111 flows sequentially from the first through hole 221, the pressure relief chamber 23, the second through hole 222, to the opening / closing chamber 112. The diameter of the second through hole 222 is larger than that of the first through hole 221. The pressure relief chamber 23 cannot be replenished in time, and the pressure in the opening / closing chamber 112 is greater than that in the pressure relief chamber 23. The elastic diaphragm 21 rises upward, thereby allowing water in the inlet chamber 111 to flow to the opening / closing chamber 112. The pilot valve control rod 24 is released, and the opening / closing stop 25 blocks the second through hole 222. At this time, water continues to be added to the pressure relief chamber 23, and the pressure in the pressure relief chamber 23 is restored, causing the elastic diaphragm 21 to reset and isolate the water inlet chamber 111 and the opening and closing chamber 112. The core function of the pilot valve 20 is to use a very small control force. In this embodiment, this small control force is the pilot valve starting component. By controlling a small pilot fluid, it indirectly and precisely drives a very large and bulky main valve to open or close. In this embodiment, the large main valve is the elastic diaphragm 21. Therefore, this structure can be used for starting under high pressure conditions.
[0031] The structure and working principle of the one-way starting mechanism 40 in this embodiment are described in detail below: (Refer to...) Figure 2 , Figure 10 , Figure 13 , Figure 16As shown, a fixed slide rail 14 is provided above the water valve body 10. The one-way starting mechanism 40 includes a push-pull rod 41 connected to the sliding piston 33. The push-pull rod 41 is slidably connected to the fixed slide rail 14. A protruding rib 411 is provided on the push-pull rod 41. A protruding rib slot 412 is provided in the middle of the protruding rib 411. A lifting slope 413 is provided at one end of the protruding rib 411 near the protruding rib slot 412. A skid plate 42 is installed on the fixed slide rail 14. Pilot valve control rod 24 A limiting block 241 is provided at the top, and a limiting groove 421 corresponding to the limiting block 241 is provided on the pry plate 42. The limiting block 241 is set in the limiting groove 421. A rotatable shaft 43 is provided in the middle of the pry plate 42. A cam 44 is provided at both ends of the shaft 43. The cam 44 is set on the rib 411. A torsion spring stop is provided in the middle of the shaft 43. A mounting shaft 422 is provided in the middle of the pry plate 42. A torsion spring 45 is provided on the mounting shaft 422. When When the sliding piston 33 drives the push-pull rod 41 to slide upward, the cam 44 slides into the rib cavity 412. When the sliding piston 33 drives the push-pull rod 41 to slide downward, the cam 44 is lifted by the lifting ramp 413, causing the torsion spring stop block 431 to push the torsion spring 45 backward. The torsion spring 45 pushes the pry bar 42 to tilt backward, causing the pry bar 42 to lift the pilot valve control rod 24 upward, thereby opening the pilot valve 20. Through the synergistic action of the cam and the rib 411, the push-pull rod 41 moves upward. During gliding, the skid plate 42 does not act on the pilot valve control rod 24. Only when the push-pull rod 41 slides down does the skid plate 42 lift the pilot valve control rod 24, thereby opening the pilot valve 20. This structural design can be started under low pressure conditions, without the need to increase the diameter of the delay valve piston to achieve a strong drive, which can save the space of the flush valve. Furthermore, the structure of the one-way start mechanism 40 is set outside the water valve body 10, and is not affected by the flow pressure, so no jamming will occur during use.
[0032] The structure and working principle of the flow channel switching component 60 in this embodiment are described in detail below: Refer to Figure 2 , Figure 6 , Figure 8As shown, the flow channel switching assembly 60 includes a switching chamber 113 located in front of the inlet pipe 11. A switching valve 50 is located within the switching chamber 113. The switching chamber 113 is connected to the first outlet pipe 12 and the second outlet pipe 13. A rotatable switching valve 50 is located within the switching chamber 113. The switching valve 50 includes an arc-shaped stop, which is used to block the passage from the inlet pipe 11 to the first outlet pipe 12 and the second outlet pipe 13. A fixed rod is located above the arc-shaped stop. The rocker assembly includes a turntable 61 connected to the switching valve 50. The arc-shaped stop is connected to the center of the turntable via the fixed rod. A protrusion is located on the side wall of the turntable 61, and a mounting hole is located within the protrusion. A swing disk 62 is connected above the turntable 61. The swing disk 62 rotates around one end of the turntable. A mounting rod is located at the other end of the swing disk 62. A rocker arm 621 is mounted above the swing plate 62 and installed in the mounting hole. By moving the rocker arm 621, the turntable 61 rotates, thereby driving the switching valve 50 to switch the water flow in the inlet pipe 11 to the first outlet pipe 12 and the second outlet pipe 13. The flow channel switching assembly 60 also includes a slide plate 63 that is slidably mounted above the fixed slide rail 14. The slide plate 63 has a mounting groove, and a detachable control plate 64 is mounted in the mounting groove. The control plate 64 has a control groove 641 that is adapted to the rocker arm 621. The rocker arm 621 is mounted in the control groove 641. Switching is performed by sliding the rocker arm 621 in the control groove 641. By setting the detachable control plate 64, different specifications of control plates 64 can be replaced. The control groove in the control plate 64 can be set to different lengths to control the flushing time. The specific scheme is as follows: Reference Figure 8 As shown, the control slot 641 includes an open slot 6411 located at the bottom of the control plate 64, a first water outlet section 6412 connected to the open slot 6411, a second water outlet section 6413 bent and connected to the first water outlet section 6412, and a third water outlet section 6414 bent and connected to the second water outlet section 6413. When the push-pull rod 41 pushes the slide plate 63 upward, the rocker arm 621 slides sequentially from the third water outlet section 6414, the second water outlet section 6413, and the first water outlet section 6412 to the open slot 6411. At this time, the pilot valve 20 is closed, and the motor is started in one direction. When the push-pull rod 41 pushes the slide plate 63 downward, the rocker arm 621 slides from the opening slot 6411 to the end of the first water outlet section 6412. At this time, the pilot valve 20 is opened, and the water flows from the inlet to the first outlet. The rocker arm 621 slides from the end of the first water outlet section 6412 to the end of the second water outlet section 6413. At this time, the water flows from the inlet to the second outlet. The rocker arm 621 slides from the end of the second water outlet section 6413 to the end of the third water outlet section 6414. The water flows from the inlet to the first outlet to replenish water, and then the pilot valve 20 is closed.
[0033] The structure and working principle of the delay valve switching component 70 in this embodiment are described in detail below: (Refer to...) Figure 1 , Figure 2 , Figure 3 As shown, the other end of the push rod 71 is connected to a lever 72 rotatably mounted on the fixed slide rail 14. The other end of the lever 72 is provided with a toggle part 721. A pin 73 is slidably mounted above the fixed slide rail 14 between two push-pull rods 41. The push-pull rod 41 is provided with a pin 73 groove corresponding to the pin 73. The middle of the pin 73 is provided with a toggle groove 731 corresponding to the toggle part 721. When the pressure relief switch 36 is pressed, the lever 72 toggle the pin 73, causing the pin 73 to be inserted into the pin 73 groove on the push-pull rod 41 corresponding to the delay valve 30, thereby activating the flush valve.
[0034] The working principle and specific implementation steps of this utility model are explained in detail below.
[0035] Reference Figures 9-14 As shown, by pressing the pressure relief start rod 322 through the pressure relief switch 36, the sealing part 3221 separates from the pressure relief hole 3211, relieving pressure in the inner cavity 311. The annular locking block 372 is set in the receiving groove 3222, thereby locking and fixing the pressure relief start rod 322. The water flow in the water inlet pipe 11 enters the outer cavity 312. The water flow pushes the sliding piston 33 upward and compresses the first spring 34. The piston rod 35 drives the push-pull rod 41 to move upward. At this time, the cam 44 slides on the rib 411 to the rib empty space 412, and the pry plate 4... 2. The pilot valve control rod 24 is not activated. The opening and closing block 25 blocks the second through hole 222. The elastic diaphragm 21 isolates the water inlet chamber 111 and the opening and closing chamber 112. The pilot valve 20 is in the closed state. At this time, the water pressure in the water inlet pipe 11 is entirely applied to the sliding piston 33. At the same time, the push-pull rod 41 pushes the slide plate 63 to move upward. The rocker arm 621 slides sequentially from the third water outlet section 6414, the second water outlet section 6413, and the first water outlet section 6412 in the control plate 64 to the opening slot 6411. Reference Figures 15-17 As shown, when the top pressure block 332 presses upward against the annular groove 374, causing the annular locking block 372 to disengage from the receiving groove 3222, the second spring 323 resets and pushes the pressure relief starting rod 322 upward. The sealing part 3221 seals the pressure relief hole 3211, and the inner cavity 311 no longer relieves pressure. Water in the outer cavity 312 slowly enters the inner cavity 311 through the water passage hole 331. Under the spring force of the first spring 35, the sliding piston 33 slowly moves downward. The piston rod 35 drives the push-pull rod 41 to move downward. (Refer to...) Figures 14-15As shown, cam 44 is lifted by inclined plane 413, causing the torsion spring 45 stop block to push the torsion spring 45 backward.
