Description

Technical Field

[0001] This invention relates to the field of bathroom fixtures technology, and more particularly to a flushing valve assembly and a toilet. Background Technology

[0002] Toilets typically have multiple flushing lines working together to ensure effective flushing. These lines are controlled by a control module. However, in some technologies, the control module cannot distribute water flow according to the flushing needs of different lines. Simultaneous supply of water to multiple lines can lead to incomplete flushing, requiring repeated flushing for thorough removal. This results in a large water volume, poor usability, and the toilet failing to balance the requirements of both flushing volume and effectiveness. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a flush valve assembly that can improve the flushing effect of the toilet and reduce the amount of water used for flushing.

[0004] The present invention also proposes a toilet having the above-described flushing valve assembly.

[0005] A flushing valve assembly according to a first aspect of the present invention includes:

[0006] The first switching component includes a housing, a water storage bladder, and a pusher. The pusher is connected to the water storage bladder. The housing has an outlet and an inlet. The water storage bladder is housed within the housing and can expand and contract according to the flow rate of water entering the housing, thereby changing the opening of the outlet and driving the pusher to move.

[0007] A water pump is connected to the water inlet through a first water inlet pipe and supplies water to the housing;

[0008] The pump spray pipe is connected at one end to the water outlet;

[0009] The second water inlet pipe is used to supply tap water;

[0010] The first valve assembly includes a first valve body and a first rocker arm. The first valve body is connected to the second water inlet pipe. The first valve body has a washing valve section. The first rocker arm is rotatably connected to the first valve body. The first rocker arm can swing under the push of the pusher.

[0011] The washing pipeline is connected at one end to the washing valve section;

[0012] The flushing valve assembly has a first working mode and a second working mode set after a preset time in the first working mode. When the flushing valve assembly is in the first working mode, the opening degree of the water outlet is H1, and the pusher pushes the first swing arm to swing so that the first swing arm opens the washing valve section, and water flows through the washing pipeline for washing and flushing, and water is replenished through the pump spray pipeline at a first flow rate Q1. When the water pump is in the second working mode, the opening degree of the water outlet is H2, and water flows through the washing pipeline for washing and flushing, and water is sprayed through the pump spray pipeline at a second flow rate Q2, where H2 > H1 and Q2 > Q1.

[0013] The flushing valve assembly according to embodiments of the present invention has at least the following beneficial effects:

[0014] In this invention, the flushing valve assembly has a larger outlet opening and a larger water flow rate in the pump spray pipe during the second working mode. The first and second working modes are performed sequentially. In the first working mode, the toilet is first replenished with water and flushed, which can clean the toilet skirt and moisten the dirt at the bottom nozzle of the toilet, making the subsequent cleaning more thorough. During this process, the water flow in the pump spray pipe is smaller, which helps to save water. When the toilet is sprayed in the second working mode, the larger outlet opening can generate a large instantaneous flow rate that is conducive to siphoning, making the toilet spray flush more thorough and improving the flushing effect.

[0015] According to some embodiments of the present invention, the flushing valve assembly further includes a second switching component and a water supply pipeline.

The second float cylinder is connected to the end of the first swing arm facing away from the pusher. When the flushing valve assembly is in the third working mode, the first float cylinder and the second float cylinder simultaneously rise to a preset position.

[0022] The flushing valve assembly also has a fourth working mode and a fifth working mode. When the flushing valve assembly is in the fourth working mode, the first rocker arm is driven to swing and open the washing valve section, and water flows through the washing pipeline for washing and flushing. When the flushing valve assembly is in the fifth working mode, the third rocker arm is driven to swing and open the spray valve section, and water flows through the valve spray pipeline for spraying and flushing.

[0023] According to some embodiments of the present invention, the flushing valve assembly further includes a second valve body and a spray pipe.

[0060] In the description of this invention, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0061] An embodiment of the present invention provides a flushing valve assembly, referring to... Figure 1 and Figure 2 The flushing valve assembly includes a first switching component 100, a water pump 200, a pump spray pipe 10, a first valve assembly 300, and a washing pipe 20. When the water pump 200 is powered, it provides the flow power for the water flow. The water flow can reach the bottom nozzle of the toilet through the pump spray pipe 10 for spray flushing or water seal replenishment, and reach the toilet skirt through the washing pipe 20 for washing. The first switching component 100 is used to switch the opening and closing states of different valves in the first valve assembly 300 so that the water flow enters the corresponding pipe through different valves for flushing.

[0062] Specifically, the first switching component 100 includes a housing 110, a water storage bladder 120, and a pusher 130. The housing 110 has an internal cavity, and the water storage bladder 120 is housed inside the housing 110. The housing 110 has an inlet 111 and an outlet 112 communicating with its internal cavity. External water can enter the housing 110 through the inlet 111 and exit through the outlet 112. The water storage bladder 120 can follow the flow rate changes of the water entering the housing 110. The expansion and contraction of the water bladder 120 alters the opening of the outlet 112. Specifically, when water is not yet inside the housing 110, the water bladder 120 is freely extended and blocks the outlet 112. When a large amount of water enters the housing 110 per unit time, the water bladder 120 is compressed more, resulting in a larger opening of the outlet 112. Conversely, when a small amount of water enters the housing 110 per unit time, the water bladder 120 is compressed less, resulting in a smaller opening of the outlet 112. Understandably, since the pusher 130 is connected to the water bladder 120, when the water bladder 120 is compressed more, the pusher 130 has a larger range of motion; conversely, when the water bladder 120 is compressed less, the pusher 130 has a smaller range of motion.

[0063] The first valve assembly 300 includes a first valve body 310 and a first rocker arm 320. The first valve body 310 has a wash valve section 311. The first rocker arm 320 is rotatably connected to the first valve body 310 and swings under the push of the pusher 130 to open or close the wash valve section 311. The flushing valve assembly also includes a first water inlet pipe 30 and a second water inlet pipe 40. One end of the first water inlet pipe 30 is connected to the water inlet 111, and the other end is connected to the water pump 200. The water pump 200 can draw water from the water tank and supply water to the inside of the housing 110 through the first water inlet pipe 30. The second water inlet pipe 40 is used to introduce tap water and is connected to the first valve body 310. One end of the pump spray pipe 10 is connected to the water outlet 112, and the other end extends to the bottom spray nozzle of the toilet. Water can flow through the pump spray pipe 10 to the bottom spray nozzle for water seal replenishment or spray flushing. One end of the washing pipe 20 is connected to the washing valve 311, and the other end extends to the toilet skirt. Water can flow through the washing pipe 20 to the toilet skirt for washing.

[0064] In this embodiment, the flushing valve assembly has a first working mode and a second working mode set after a preset time in the first working mode. Specifically, when the flushing valve assembly is in the first working mode under power, the water pump 200 drives water to flow into the housing 110 through the inlet 111, the water sump 120 is compressed, the outlet 112 is opened, and the opening degree of the outlet 112 is H1. The pusher 130 follows the compression of the water sump 120 to push the first swing rod 320 to swing. The first swing rod 320 opens the washing valve 311. At this time, the washing pipeline 20 is in a conductive state, and tap water enters the washing pipeline 20 through the second inlet pipeline 40 to wash and flush the toilet. At the same time, the water flowing into the housing 110 flows through the outlet 112 to the pump spray pipeline 10, and the water flow replenishes the toilet with a first flow rate Q1. After operating in the first working mode for a preset time, the flushing valve assembly enters the second working mode. In the second working mode, the water reservoir 120 continues to compress, the opening of the outlet 112 switches to H2, the pusher 130 continuously pushes the first swing arm 320, and the wash valve 311 remains in the conductive state. Tap water flows through the wash pipe 20 to wash and flush the toilet; simultaneously, water is sprayed onto the toilet at a second flow rate Q2. In the above, H2 > H1, Q2 > Q1.

[0065] Therefore, in the first working mode, the opening of the outlet 112 and the flow rate of water in the pump spray pipe 10 are relatively small, while in the second working mode, the opening of the outlet 112 and the flow rate of water in the pump spray pipe 10 are relatively large. The first and second working modes are performed sequentially. In the first working mode, the toilet is first replenished with water seal and flushed, which can clean the toilet skirt and wet the dirt at the bottom nozzle of the toilet, making the subsequent cleaning more thorough. During this process, the water flow in the pump spray pipe 10 is relatively small, which helps to save water. In the second working mode, when the toilet is sprayed and flushed, the larger opening of the outlet 112 can generate a large instantaneous flow rate that is conducive to siphoning, making the toilet spray flush more thorough. At the same time, the flushing pipe 20 uses tap water for flushing, which can improve the flushing effect of the toilet.

[0066] It should be noted that the flushing valve assembly can use water in the water tank and tap water for flushing in both the first and second working modes, overcoming the defect of insufficient flushing caused by a single water source.

[0067] In one embodiment, the operating power of the water pump 200 in the first operating mode is set to be less than that in the second operating mode, so that the water flow rate delivered to the housing 110 by the first inlet pipe 30 in the first operating mode is less than that delivered to the housing 110 in the second operating mode. Specifically, the water pump 200 is set to operate at half power when the flushing valve assembly is in the first operating mode, and at full power when the flushing valve assembly is in the second operating mode. Compared to the case where the water pump 200 operates directly at full power, the peak current of the water pump 200 during pneumatic operation can be eliminated, thus protecting the circuit. The water pump 200 is fixed to the bottom of the water tank and can be completely covered by water, which has the effect of cooling and noise reduction, and can prevent dry pumping.

[0068] The water sac 120 is configured to elastically contract under pressure and elastically recover after the pressure is removed, such as being configured as a bellows. In one embodiment, the pusher 130 moves in a movable manner and contacts the first swing arm 320. During its movement, the pusher 130 pushes the first swing arm 320 to swing based on its rotational connection position with the first valve body 310. The contraction of the water sac 120 can be directly converted into the movement of the pusher 130, resulting in high transmission efficiency. Furthermore, the water sac 120 is hollow inside to facilitate its deformation and contraction, allowing changes in the water flow into the housing 110 to effectively reflect the movement of the pusher 130. Part of the pusher 130 is housed within the water sac 120, with one end connected to the bottom of the water sac 120 and the other end extending to the outside of the housing 110. It can push the first swing rod 320 to swing. When the water sac 120 contracts, the pusher 130 moves upward and pushes one end of the first swing rod 320 upward. When the water sac 120 extends, the pusher 130 moves downward and removes the pushing force on the first swing rod 320.

[0069] To make the movement of the pusher 130 smoother, in one embodiment, the top of the housing 110 is provided with a channel arranged along the moving direction of the pusher 130. The channel is connected to the cavity inside the housing 110. The pusher 130 passes through the channel, and the first swing rod 320 is located above the pusher 130. When the pusher 130 moves to the top and contacts the first swing rod 320, and continues to move upward, the first swing rod 320 is pushed and swings. During this process, the channel guides the movement of the pusher 130, so that the pusher 130 always moves vertically, avoiding the pusher 130 from tilting and disengaging from the first swing rod 320.

[0070] Furthermore, the inlet 111 is located at the bottom of the housing 110. The water flowing into the housing 110 from the inlet 111 is located at the lower part of the water storage bladder 120, causing the water storage bladder 120 to contract upward under the pressure of the water flow and buoyancy, resulting in a faster contraction of the water storage bladder 120. In addition, the first switching component 100 also includes a baffle 140, which is connected to the bottom of the water storage bladder 120. The side of the baffle 140 contacts the inner side wall of the housing 110. On the one hand, the bottom surface of the baffle 140 is relatively flat, with a large contact area with the water flow. When the baffle 140 moves, it is guided by the inner wall of the housing 110, making the movement of the pusher 130 more stable. On the other hand, a sealed cavity is formed between the baffle 140 and the bottom wall of the housing 110, which can effectively transmit the water flow pressure to the water storage bladder 120, causing the water storage bladder 120 to contract rapidly. The top of the water bladder 120 is open, allowing the pusher 130 to extend out. The top edge of the water bladder 120 is connected to the housing 110, and the internal cavity of the water bladder 120 is also sealed.

[0071] The water outlet 112 is located on the side wall of the housing 110, in the lower middle part of the housing 110. When the flushing valve assembly is in standby mode, the water sump 120 is extended, and the side wall of the baffle 140 blocks the water outlet 112. When the flushing valve assembly enters the first or second working mode, the water sump 120 contracts, the baffle 140 moves upward, and gradually opens the water outlet 112 to change the opening degree of the water outlet 112. It should be noted that in this embodiment, the opening degree of the water outlet 112 refers to the distance between the area of ​​the water outlet 112 and the interior of the housing 110 in the moving direction of the pusher 130.

[0072] Understandably, the first valve body 310 should have a channel communicating with the second water inlet pipe 40. When the flushing valve 311 is open, this channel connects to the flushing pipe 20 through the flushing valve 311, and tap water enters the flushing pipe 20 through the flushing valve 311. In one embodiment, the flushing valve 311 has a pressure relief hole. When the flushing valve assembly is in standby mode, a portion of the first rocker arm 320 blocks the pressure relief hole, and the flushing valve 311 is closed. When the flushing valve assembly is in the first working mode and the second working mode, the first rocker arm 320 moves away from the pressure relief hole, and the flushing valve 311 is opened. Specifically, the pressure relief hole is located between the rotational connection position of the first rocker arm 320 and the first valve body 310 and the contact position between the first rocker arm 320 and the pusher 130, and the pressure relief hole is located below the first rocker arm 320. When the pusher 130 pushes the first rocker arm 320 upward, the first rocker arm 320 swings upward and moves away from the pressure relief hole, thereby opening the washing valve 311.

[0073] In addition, the first swing rod 320 is equipped with a rubber plug for engaging with the pressure relief hole, ensuring the sealing effect of the first swing rod 320 on the pressure relief hole. Furthermore, after the first swing rod 320 releases the seal on the pressure relief hole, the pressure relief hole is directly connected to the external atmosphere, which can generate a large pressure difference and achieve a large flow rate of water output.

[0074] In this invention, the flushing valve assembly also has a third operating mode following the second operating mode. Because the flushing valve assembly performs a high-flow-rate flush on the toilet in the second operating mode, causing the water level in the tank to drop, the flushing valve assembly replenishes water to the tank in the third operating mode, raising the water level in the tank. Specifically, refer to... Figure 2 and Figure 3 The flushing valve assembly also includes a second switching component 400 and a water supply pipe 50. The second switching component 400 includes a first float cup 410, a first float cylinder 420, and a switching element 430. The first float cylinder 420 is housed inside the first float cup 410 and can rise and fall with changes in the liquid level inside the first float cup 410. The switching element 430 is drivenly connected to the first float cylinder 420 and can move with the rise and fall of the first float cylinder 420. When the flushing valve assembly is in the first working mode and the second working mode, the water in the water tank is at a high level. At this time, the first float cylinder 420 is at a higher height inside the first float cup 410. The switching element 430 blocks the water supply pipe 50 and avoids the flushing. When the first swing arm 320 opens the washing valve 311, tap water can be used for washing and rinsing through the washing pipe 20. When the flushing valve group is in the third working mode, the water in the tank is at a low level because the flushing valve group has already performed jet flushing. At this time, the height of the first float 420 in the first float cup 410 is relatively low. The switching component 430 moves to block the washing pipe 20 and avoids the water replenishment pipe 50. Tap water enters the water replenishment pipe 50 through the washing valve 311 to replenish the water tank. When the water level in the tank rises to the preset height, the switching component 430 switches again to block the water replenishment pipe 50 and avoids the washing pipe 20. At this time, water replenishment stops.

[0075] By setting a third working mode, the water tank is always full after the flushing valve assembly completes the flushing action and when it is in standby mode, so that the flushing valve assembly can directly use the water in the water tank for water seal replenishment or spray flushing when it is used again.

[0076] Understandably, the movement of the switching component 430 is not limited to swinging or moving. For example, the switching component 430 is connected to the first float 420 and moves with the rise and fall of the first float 420. The water supply pipe 50 and the washing pipe 20 are arranged side by side vertically, and the water supply pipe 50 is located above the washing pipe 20. The switching component 430 is provided with a first blocking part, a hollow part and a second blocking part from top to bottom. The hollow part is set as a through cavity. When the flushing valve assembly is in the first and second working modes, the first shielding part corresponds to and blocks the water supply pipe 50, and the hollow part corresponds to and avoids the washing pipe 20. Tap water is used for washing and flushing through the washing pipe 20. When the flushing valve assembly is in the third working mode, the switching part 430 rises, the hollow part corresponds to and avoids the water supply pipe 50, the second shielding part corresponds to and blocks the washing pipe 20, and tap water is used to replenish water to the water tank through the water supply pipe 50.

[0077] In another embodiment, the second switching assembly 400 further includes a second swing arm 440. One end of the second swing arm 440 is rotatably connected to the first float 420, and the other end is connected to the switching member 430. The switching member 430 is rotatably connected to the first valve body 310. The second swing arm 440 rotates with the rise and fall of the first float 420 and synchronously drives the switching member 430 to swing. Specifically, the extension directions of the washing pipe 20 and the water supply pipe 50 are not parallel and are at a certain angle to each other. An active gap 450 is defined between the end face of the washing pipe 20 and the end face of the water supply pipe 50. The switching member 430 can swing within the active gap 450. When the switching member 430 swings to contact the end face of the water supply pipe 50, the switching member 430 blocks the water supply pipe 50. When the switching member 430 swings to contact the end face of the washing pipe 20, the switching member 430 blocks the washing pipe 20.

[0078] Understandably, the second swing arm 440 has an oblong hole, and the top of the first float 420 is provided with a first pin. The first pin is inserted into the oblong hole and can slide along the oblong hole to convert the raising and lowering of the first float 420 into the swinging of the switching element 430 via the first swing arm 320. For example, as... Figure 2 and 3As shown, the washing pipe 20 is located above the water supply pipe 50. When the first float 420 is in a high position, the switching element 430 is in the lowest position and blocks the top end face of the water supply pipe 50. When the first float 420 descends, the second swing rod 440 and the switching element 430 rotate clockwise based on the rotation center of the switching element 430. The switching element 430 swings from the lowest position to the highest position and swings to the end face of the washing pipe 20. At this time, the switching element 430 leaves and avoids the water supply pipe 50, and tap water is supplied to the water tank through the water supply pipe 50. During the process of the water level in the water tank rising, the first float 420 gradually moves upward, and the second swing rod 440 rotates counterclockwise based on the rotation center of the switching element 430. When the first float 420 moves back to the high position, the switching element 430 swings to the end face of the water supply pipe 50, and water supply stops.

[0079] Furthermore, in one embodiment, the end faces of the washing pipe 20 and / or the water supply pipe 50 are set as bevels to reduce the space of the movable gap 450, so that the switching member 430 can more easily rotate at a small angle to block the washing pipe 20 or the water supply pipe 50.

[0080] In addition, the second switching assembly 400 also includes a switching part 412, which has a valve chamber 413 inside. At least a portion of the washing pipe 20 and the water supply pipe 50 are located in the valve chamber 413. The switching member 430 is rotatably connected to the switching part 412 and located in the valve chamber 413. The end face of the washing pipe 20 and the end face of the water supply pipe 50 located in the valve chamber 413 can cooperate with the switching member 430. The water flow entering the valve chamber 413 from the washing valve part 311 is diverted. When the switching member 430 blocks the end face of the water supply pipe 50, the water flows through the washing pipe 20 for washing and rinsing. When the switching member 430 blocks the end face of the washing pipe 20, the water flows through the water supply pipe 50 to replenish water to the water tank.

[0081] For example, the scrubbing pipe 20 extends horizontally and the water supply pipe 50 extends vertically. The scrubbing pipe 20 is located above the water supply pipe 50. The side of the scrubbing pipe 20 facing the water supply pipe 50 has a slope. The slope and the top end face of the water supply pipe 50 define an movable notch 450 for the switching member 430 to swing. On the one hand, the swing angle of the switching member 430 is reduced, so that the switching member 430 can quickly block the scrubbing pipe 20 or the water supply pipe 50. On the other hand, the water supply pipe 50 can extend downward to below the liquid surface when the water level in the tank is low, so as to reduce the noise of water intake.

[0082] Furthermore, the side wall of the flushing pipe 20 has a through bypass hole 21, which communicates with the valve chamber 413. When the switching element 430 blocks the end face of the flushing pipe 20, the water flowing into the valve chamber 413 replenishes the water tank through the water supply pipe 50 and enters the flushing pipe 20 through the bypass hole 21 for water seal replenishment, thereby improving the flushing effect. It is understood that there is a gap between the outer wall of the flushing pipe 20 and the inner wall of the switching element 412. The water flowing into the valve chamber 413 enters the bypass hole 21 through the gap between the flushing pipe 20 and the inner wall of the switching element 412, and then replenishes the water seal through the flushing pipe 20.

[0083] In this invention, reference is made to Figure 2 The second switching assembly 400 also includes a second float cup 150 and a second float cylinder 160. The second float cylinder 160 is housed within the second float cup 150 and can rise and fall in response to changes in the liquid level within the second float cylinder 160. The second float cylinder 160 is connected to the end of the first swing rod 320 facing away from the pusher 130 at its swing center. Specifically, as shown... Figure 2 As shown, the left side of the first swing rod 320 cooperates with the pusher 130, and the right side is connected to the second float 160. When the pusher 130 pushes the first swing rod 320 upward, the first swing rod 320 swings clockwise, and the right end of the first swing rod 320 presses down on the second float 160. When the water pump 200 is not working, the pusher 130 removes the pushing force on the first swing rod 320 and moves down with the extension of the water storage bladder 120. When the water tank is replenished, the second float 160 gradually moves up as the water level in the second float cup 150 rises, and the second swing rod 440 swings counterclockwise. When the second float 160 rises to the highest position, the second swing rod 440 blocks the pressure relief hole of the wash valve 311, and the wash valve 311 is closed at this time.

[0084] Specifically, the first swing arm 320 is provided with an oblong hole, and the top of the second float 160 is provided with a second pin. The second pin is inserted into the oblong hole and can slide along the oblong hole so that the movement of the second float 160 is converted into the swing of the first swing arm 320.

[0085] Understandably, during the water tank replenishment process, when the water level in the tank reaches a certain height, the water in the tank flows into the first float cup 410 and the second float cup 150. As the water flows into the first float cup 410 and the second float cup 150, the first float 420 and the second float 160 rise continuously. When the first float 420 rises to the point where the trigger switching element 430 blocks the water replenishment pipe 50, the water tank replenishment and water seal replenishment stop. When the first float 420 rises to the point where the trigger swing rod 320 is activated, the scrubbing valve 311 closes.

[0086] Both water seal replenishment and water tank replenishment must be performed with the flushing valve 311 open. To ensure that the water replenishment is completed before the flushing valve 311 is closed, in this embodiment, when the flushing valve group is in the third working mode, the first float 420 and the second float 160 float up to a preset position simultaneously. When the first float 420 floats up to the preset position and triggers the switching component 430 to block the water replenishment pipeline 50, the second float 160 floats up to a preset height and triggers the first swing arm 320 to close the flushing valve, and the water replenishment operation ends.

[0087] In one embodiment, the first float 410 and the second float 150 are set to have the same volume and height. Water from the tank flows into the first float 410 and the second float 150 simultaneously, causing the first float 420 and the second float 160 to rise to a preset position simultaneously. Furthermore, the first float 410 and the second float 150 are provided with water inlet notches at their top edges, with the lowest points of the notches at the same height. Water from the tank enters the first float 410 and the second float 150 simultaneously through these notches. The water inlet notches slow down the rising speed of the first float 420 and the second float 160, making their rising more stable.

[0088] Understandably, the first float cup 410 and the second float cup 150 can be set to be separate from each other, so that the first float cup 410 and the second float cup 150 are independent of each other; or the first float cup 410 and the second float cup 150 can be connected as a whole, sharing a side wall, so that the two can be installed together.

[0089] The second switching component 400 also includes a first float 460, which is movably connected to the bottom of the first float cup 410 and can block or open the first inlet 411 at the bottom of the first float cup 410. The second switching component 400 also includes a second float 170, which is movably connected to the bottom of the second float cup 150 and can block or open the second inlet 151 at the bottom of the second float cup 150. The lowest position of the first float 460 is lower than the lowest position of the second float 170. The first float 460 and the second float 170 are buoyed by the water in the tank. When the water level in the tank rises to contact the lowest position of the first float 460 and the second float 170, the first float 460 and the second float 170 float upwards, the first inlet 411 is closed by the first float 460, and the second inlet 151 is closed by the second float 170. When the water level in the tank drops and tends to move away from the lowest position of the first float 460 and the second float 170, the first float 460 and the second float 170 drop downwards. Since the lowest position of the first float 460 is lower than the lowest position of the second float 170, when the water level in the tank drops, the second float 170 falls before the first float 460, the second inlet 151 opens before the first inlet 411, the water in the second float cup 150 flows out through the second inlet 151 first, the second float 160 falls before the first float 420, and drives the first swing rod 320 to open the washing valve 311, ensuring that the washing and rinsing are carried out in the open state of the washing valve 311, and avoiding interruption of washing.

[0090] This invention also includes a power-off flushing mode, enabling the flushing valve assembly to handle flushing under both powered and power-off conditions. Specifically, refer to... Figure 1 and Figure 4 The first valve body 310 also includes a jet valve section 314, and the first valve assembly 300 also includes a third rocker arm 330. The third rocker arm 330 is connected to the first valve body 310 and can be driven to swing to close or open the jet valve section 314. The flushing valve assembly also includes a valve-jet pipeline 60, one end of which is connected to the jet valve section 314. When the jet valve section 314 is opened, tap water enters the valve-jet pipeline 60 from the second water inlet pipeline 40 through the jet valve section 314 to spray and flush the toilet.

[0091] The flushing valve assembly includes a fourth working mode and a fifth working mode that operate in the power-off state. When the flushing valve assembly is in the fourth working mode, the first swing arm 320 is manually driven. The first swing arm 320 swings and opens the wash valve 311. Tap water enters the wash pipe 20 through the second water inlet pipe 40 and the wash valve 311 to wash the toilet. When the flushing valve assembly is in the fifth working mode, the third swing arm 330 is also manually driven. The third swing arm 330 swings and opens the spray valve 314. Tap water enters the spray pipe 60 through the second water inlet pipe 40 and the spray valve 314 to spray and flush.

[0092] Understandably, the third rocker arm 330 is rotatably connected to the injection valve part 314. A counterweight 331 is provided at one end of the third rocker arm 330. The manually driven part of the third rocker arm 330 and the counterweight 331 are located on both sides of the rotation center of the third rocker arm 330, so that the third rocker arm 330 is kept in a normally closed state under the action of the counterweight 331. The user's driving method for the first rocker arm 320 and the third rocker arm 330 is not limited to pressing or flicking. For example, taking the first rocker arm 320 as an example, the user drives the first rocker arm 320 to rotate by pressing. The pressing position of the first rocker arm 320 is set near the connection position between the first rocker arm 320 and the second float 160. When the first rocker arm 320 is pressed, it moves away from the pressure relief hole of the flush valve 311, and the flush valve 311 opens. Alternatively, taking the third rocker arm 330 as an example, the user drives the third rocker arm 330 to rotate by flicking. The end of the third rocker arm 330 away from the counterweight 331 is connected to the lever through a rod. The lever is located outside the toilet. When the user flicks the lever, the lever drives the third rocker arm 330 to swing and opens the jet valve 314.

[0093] For example, the opening and closing method of the third lever 330 on the injection valve 314 can also be configured such that the third lever 330 blocks or avoids the pressure relief hole of the injection valve 314; or, the third lever 330 blocks or avoids the internal passage of the injection valve 314.

[0094] In another embodiment, reference Figure 5 The flushing valve assembly also includes a third switching component 500, which is manually operated by the user and sequentially triggers the first swing arm 320 and the third swing arm 330. A single operation by the user can activate the flushing valve assembly to perform the fourth and fifth working modes, realizing the washing and spraying of the toilet. The third switching component 500 includes a first pressure rod 510, a second pressure rod 520, and a push rod 530. The first pressure rod 510 is connected to the first swing arm 320, the second pressure rod 520 is connected to the second swing arm 440, and the push rod 530 can be driven to sequentially push the first pressure rod 510 and the second pressure rod 520. When the first pressure rod 510 is pushed, the first swing arm 320 is triggered and opens the washing valve 311. When the second pressure rod 520 is pushed, the third swing arm 330 is triggered and opens the spray valve 314.

[0095] Specifically, after setting the fifth working mode and the fourth working mode, when the flushing valve assembly is in the fourth working mode, the push rod 530 pushes the first pressure rod 510, causing the first swing rod 320 to swing and open the washing valve section 311. At this time, tap water enters the washing pipeline 20 through the washing valve section 311 for washing. As the push rod 530 continues to move, the flushing valve assembly enters the fifth working mode. At this time, the push rod 530 pushes the second pressure rod 520 and releases the push on the first pressure rod 510. The third swing rod 330 swings and opens the spray valve section 314. The first swing rod 320 returns to its original position, the washing valve section 311 closes, and tap water sprays through the valve spray pipeline 60 for washing. Thus, when the user continuously drives the push rod 530 to move, the push rod 530 selectively triggers the first swing rod 320 and the third swing rod 330, causing the flushing valve assembly to sequentially enter the fourth and fifth working modes, and sequentially perform washing and spraying.

[0096] The movement of the push rod 530 is not limited to rotation or movement; therefore, the user can drive the push rod 530 by pressing or twisting. For example, in the case where the push rod 530 drives the first swing arm 320 and the third swing arm 330 to swing by rotation, the outer circumferential surface of the push rod 530 is provided with a protruding first driving part and a second driving part. The first driving part and the second driving part are spaced apart along the arrangement direction of the first pressure rod 510 and the second pressure rod 520, and their projections along the rotation axis of the push rod 530 are offset circumferentially on the push rod 530. When the user twists the push rod 530, causing it to rotate to a first angle, the first driving part and the first pressure rod 510... The first drive unit contacts and presses the first pressure rod 510, causing the first swing rod 320 to swing. The second drive unit does not contact the second pressure rod 520. At this time, the washing valve 311 opens and the spray valve 314 closes, and washing is performed. When the user continues to twist the push rod 530 to the second angle, the first drive unit moves away from the first pressure rod 510, the first pressure rod 510 returns to its original position, the second drive unit contacts and presses the second pressure rod 520, causing the third swing rod 330 to swing. At this time, the spray valve 314 opens and the washing valve 311 closes, and tap water is sprayed and washed through the valve spray pipe 60.

[0097] Furthermore, the push rod 530 is rotatably connected to the water tank, toilet body 800, or other components. A torsion spring can be fitted onto the push rod 530, with one end connected to the push rod 530 and the other end connected to the water tank or toilet body 800. This spring is used to reset the push rod 530 after it has driven the first swing arm 320 and the third swing arm 330. Understandably, when the user twists the push rod 530, the torsion spring is compressed and accumulates elastic force. After the flushing is complete, the user removes the twisting action on the push rod 530, and the push rod 530 rotates in the opposite direction under the elastic force of the torsion spring until it returns to its initial state. Additionally, during the return process, the push rod 530 again contacts and presses the first pressure rod 510 through the first drive unit, and the second drive unit moves away from the second pressure rod 520. At this time, the flush valve 311 opens, and water is replenished to the toilet through the flush pipe 20.

[0098] In another embodiment, the push rod 530 drives the first swing rod 320 and the third swing rod 330 to swing in a movable manner. Specifically, the push rod 530 is driven to move along the first direction. The side of the push rod 530 is provided with a first clearance part 531, a first push part 532, a second clearance part 533, a second push part 534 and a third clearance part 535 in sequence along the first direction. The first pressure rod 510 and the second pressure rod 520 are distributed at intervals along the first direction. When the flushing valve assembly is in standby mode, part of the first pressure rod 510 is accommodated in the second clearance part 533, and part of the second pressure rod 520 is accommodated in the third clearance part 535. At this time, neither the first pressure rod 510 nor the second pressure rod 520 is pressed by the push rod 530, and the flushing valve part 311 and the spray valve part 314 are closed. When the user presses the push rod 530, the push rod 530 moves in the first direction, and the flushing valve assembly enters the fourth working mode. At this time, the first pushing part 532 contacts the first pressure rod 510 and pushes the first pressure rod 510. The first pressure rod 510 drives the first swing rod 320 to swing, and part of the second pressure rod 520 is accommodated in the third clearance part 535. The first pressure rod 520 is not pressed when it is accommodated in the third clearance part 535, the washing valve part 311 is opened and the spray valve part 314 is closed, and tap water is used for washing and rinsing through the washing pipe 20; the user continues to press the push rod 530 to make the flushing valve group enter the fifth working mode. At this time, part of the first pressure rod 510 is accommodated in the first clearance part 531, the first pressure rod 510 is not pressed, and the second push part 534 contacts and presses the second pressure rod 520. The second pressure rod 520 drives the third swing rod 330 to swing, the spray valve opens and the washing valve part 311 closes, and tap water is used for spraying and rinsing through the valve spray pipe 60.

[0099] The third switching assembly 500 also includes a first elastic reset member 540, which is used to return to its original position after the push rod 530 completes driving the first swing rod 320 and the second swing rod 440. The first elastic reset member 540 is connected to the push rod 530 and provides an elastic force away from the first direction. Specifically, the flushing valve assembly has a bracket for mounting the push rod 530, which is slidably connected to the bracket. One end of the first elastic reset member 540 is connected to the push rod 530, and the other end is connected to the bracket. When the push rod 530 moves in the first direction, the first elastic reset member 540 is compressed. After the user removes the pressure on the push rod 530, the first elastic reset member 540 releases the elastic force and pushes the push rod 530 back to its original position.

[0100] Understandably, the flushing valve assembly also has a sixth working mode following the fifth working mode. When the flushing valve assembly is in the sixth working mode, the push rod 530 is no longer pressed by the user and is reset by the elastic restoring force of the first elastic reset member 540, moving away from the first direction. At this time, the second pressure rod 520 returns to a state where it is partially accommodated in the third clearance part 535, causing the spray valve part 314 to close and the spray flushing to stop. The first pressure rod 510 returns to a state where it is pressed by the first push part 532, and drives the first swing rod 320 to swing, causing the scrubbing valve part 311 to open, and tap water is replenished through the scrubbing pipe 20. As the push rod 530 continues to return to its original position, the first pressure rod 510 finally returns to a state where it is partially accommodated in the second clearance part 533. At this time, the water seal replenishment stops, and the flushing valve assembly re-enters the standby state.

[0101] Furthermore, the third switching assembly 500 also includes a second elastic reset member 550 and a third elastic reset member 560. The second elastic reset member 550 is connected to the first pressure rod 510 and provides an elastic force toward the push rod 530 to the first pressure rod 510. After the first pressure rod 510 disengages from the first push part 532, it pushes the first pressure rod 510 toward the push rod 530, so that the first pressure rod 510 is avoided by the first avoidance part 531 or the second avoidance part 533, and drives the first swing arm 320 to swing, thereby closing the scrubbing valve part 311. The third elastic reset member 560 is connected to the second pressure rod 520 and provides an elastic force toward the push rod 530 to the second pressure rod 520. After the second pressure rod 520 disengages from the second push part 534, it pushes the second pressure rod 520 toward the push rod 530, so that the second pressure rod 520 is avoided by the third avoidance part 535, and drives the third swing arm 330 to swing, thereby closing the spray valve part 314.

[0102] Specifically, the flushing valve assembly includes a base 600. A first pressure rod 510 and a second pressure rod 520 are both vertically slidably connected within the base 600, with their upper ends extending from the base 600 to engage with a push rod 530, and their lower ends connected to a first swing rod 320 and a third swing rod 330. A first elastic reset member 540 is sleeved on the outside of the first pressure rod 510 and abuts upward against the flange on the outer surface of the first pressure rod 510. A second elastic reset member 550 is sleeved on the outside of the second pressure rod 520 and abuts upward against the flange on the outer surface of the second pressure rod 520.

[0103] In addition, the first clearance portion 531, the second clearance portion 533, and the third clearance portion 535 are configured as recesses on the outer surface of the push rod 530, with the recesses facing away from the first pressure rod 510 or the second pressure rod 520; the first push portion 532 and the second push portion 534 are configured as parts of the outer surface of the push rod 530, with the first push portion 532 located between the first clearance portion 531 and the second clearance portion 533, and the second push portion 534 located between the second clearance portion 533 and the third clearance portion 535. The outer surface of the push rod 530 has no protruding structure, making the connection between the push rod 530, the first pressure rod 510, and the second pressure rod 520 more compact.

[0104] like Figure 1 The bottom of the water tank is equipped with a support structure 70 for mounting the water pump 200. The support structure 70 has a connector 71 for connecting the pipeline, and the connection is sealed. The pipeline is led through the connector 71 to the bottom spray nozzle of the toilet, and the water flow sprays and flushes the toilet. In one embodiment, both the pump spray pipeline 10 and the valve spray pipeline 60 are connected to the connector 71 and extend to the bottom spray nozzle of the toilet. When the power is on, the water pump 200 draws water from the water tank and flows through the pump spray pipeline 10 to the bottom spray nozzle to spray and flush the toilet. When the power is off, tap water flows through the valve spray pipeline 60 to the bottom spray nozzle to spray and flush the toilet. The separate installation of the valve spray pipeline 60 and the pump spray pipeline 10 makes the spraying and flushing more stable under both powered and unpowered conditions.

[0105] In another embodiment, reference Figures 6 to 8The flushing valve assembly also includes a second valve body 700 and a jet pipe 80. The second valve body 700 includes a first valve section 710, a second valve section 720, and a blocking member 730. The first valve section 710 is connected to the valve jet pipe 60, and the second valve section 720 is connected to the pump jet pipe 10. The blocking member 730 is movably connected inside the second valve body 700 and can be moved by the water flow entering the second valve body 700. It can selectively close the first valve section 710 or the second valve section 720. One end of the jet pipe 80 is connected to the outlet of the second valve body 700, and the other end extends to the bottom spray nozzle of the toilet. Specifically, when water flows through the valve spray pipe 60 to the second valve body 700, the blocking member 730 is pushed by the water flowing through the first valve section 710 towards the second valve section 720, closing the second valve section 720 and allowing water to flow through the first valve section 710 into the spray pipe 80, thereby spraying and flushing the toilet. When water flows through the pump spray pipe 10 to the second valve section 720, the blocking member 730 is pushed by the water flowing through the second valve section 720 towards the first valve section 710, closing the first valve section 710 and allowing water to flow through the second valve section 720 into the spray pipe 80, thereby spraying and flushing the toilet. Thus, in both powered and de-powered conditions, the water flow can reach the bottom spray nozzle through the spray pipe 80, making the piping design of the flushing valve assembly simpler and the connection between the pipe and the connector 71 more convenient.

[0106] In one embodiment, the first valve 710 is configured to block the end face of the valve spray pipe 60 in a normally closed state, and the second valve 720 is configured to close the end face of the pump spray pipe 10 in a normally closed state. When water flows in the valve spray pipe 60, the water flow pushes the first baffle to move, making the valve spray pipe 60 unobstructed, while the second baffle remains in its original state, thus realizing spray flushing in the power-off state. When water flows in the pump spray pipe 10, the water flow pushes the second baffle to move, making the pump spray pipe 10 unobstructed, while the first baffle remains in its original state, thus realizing spray flushing in the power-on state.
