Description

Technical Field

[0001] This invention relates to the field of fluid control technology, and in particular to a toilet flushing system. Background Technology

[0002] In the existing technology, the working process of the toilet flushing system is as follows: first, the rim area is flushed, then the bottom is flushed, and after the bottom area is flushed, the rim area is flushed a second time; after the entire flushing process is completed, water is replenished to the tank by the tap water pipe.

[0003] This flushing method relies entirely on the water tank for water supply. The flushing of the rim area and the flushing of the bottom area are completely independent, which will result in obvious flushing noise in the bottom area, affecting the user experience. In addition, in order to meet the total flushing water consumption, the water tank volume will be increased, which is not conducive to the overall layout and appearance of the toilet. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a toilet flushing system that can solve the above problems.

[0005] To achieve the above objectives, the present invention proposes a toilet flushing system, including a built-in power water source, an external power water source, and a flushing control device. The built-in power water source performs the first flushing process through a water tank and the flushing control device. After a period of time, the flushing control device switches, and the built-in power water source and the external power water source begin flushing simultaneously.

[0006] Preferably, after the internal and external power water sources have finished rinsing simultaneously, the external power water source continues rinsing until rinsing is complete.

[0007] Preferably, the flushing water path corresponding to the first flushing process is the toilet seat flushing water path. When the two water paths flush simultaneously, the built-in power water source flushes the bottom area of ​​the toilet bowl, and the external power water source flushes the toilet seat area.

[0008] The present invention also proposes a flushing control device, including a flushing system combination valve. The flushing system combination valve is provided with an inlet A, an inlet B, an outlet A, and an outlet B. The flushing system combination valve is provided with a water supply chamber A and a water supply chamber B. The inlet A is connected to the water supply chamber A through an inlet water passage A. The inlet B is connected to the water supply chamber B through an inlet water passage B. The water supply chamber A is connected to the outlet B and a first valve is provided at the connection point. The water supply chamber A and the water supply chamber B are connected and a second valve is provided at the connection point. The water supply chamber B is connected to the outlet A and a third valve is provided at the connection point.

[0009] Preferably, the inlet A is connected to the outlet channel of the water tank, and a water pump is installed on the outlet channel; the inlet B is connected to the inlet channel of the tap water pipe; the outlet A is connected to the flushing water path of area A; and the outlet B is connected to the flushing water path of area B.

[0010] As a preferred option, the flushing water path in Zone A is for flushing the toilet seat area, and the flushing water path in Zone B is for flushing the toilet bowl area.

[0011] Preferably, a rotating shaft is rotatably installed in water supply chamber A and water supply chamber B. A first valve, a second valve and a third valve are connected to the rotating shaft. When the rotating shaft rotates to a first working angle, the second valve and the third valve open and the first valve closes. When the rotating shaft rotates to a second working angle, the second valve closes and the first valve and the third valve open.

[0012] Preferably, the rotating shaft is connected to a switching mechanism, which controls the rotating shaft to rotate to a first working angle or a second working angle.

[0013] Preferably, the switching mechanism is a motor.

[0014] Preferably, the rotating shaft is connected to the drive shaft via a transmission gear set, the drive shaft is equipped with a drive handle, the drive handle is connected to a return spring, and the power source of the switching mechanism is hydrodynamic or float-driven force.

[0015] Preferably, the switching mechanism includes a water inlet channel with a mounting base in the channel. A push rod is movably mounted on the mounting base, and a seal for closing the water inlet channel is provided on the push rod. A compression spring is provided between the seal and the mounting base. The end of the push rod away from the seal is connected to a pressure rod for switching the water path. When water enters the water inlet channel, the push rod pushes the pressure rod downward, thereby driving the drive handle to press down, which in turn drives the rotating shaft to rotate, thereby switching the water path. After the water inlet stops, the push rod returns to its original position under the action of the compression spring, and the drive handle returns to its original position under the action of the return spring.

[0016] Preferably, the switching mechanism is a float, and the drive handle is connected to the float via a linkage mechanism. When the float descends to a certain position, it triggers the linkage mechanism, which in turn drives the drive handle to press down, thereby causing the rotating shaft to rotate. After the float rises again, the reset spring controls the drive handle to return to its original position.

[0017] Preferably, the transmission gear set is a bevel gear set.

[0018] Preferably, water inlet valve A is provided on water inlet channel A; water inlet valve B is provided on water inlet channel B.

[0019] The beneficial effects of this invention are as follows: In use, the first flushing of the ring wall area is supplied with water by a water pump in the water tank, ensuring stable water pressure during the first flushing and preventing it from being affected by tap water pressure. The second flushing of the ring wall area uses tap water, which can reduce the design volume of the water tank. This invention performs a second flushing of the ring wall area while rinsing the bottom area, and the water used for the ring wall area flushing reduces the noise generated by water impacting the ceramic wall and siphon during the bottom area flushing, achieving a quiet rinsing process. The present invention integrates the first valve, the second valve and the third valve on the same rotating shaft structure. Different rotation angles of the rotating shaft correspond to the opening and closing combination states of each valve, thereby switching to form different water supply and water outlet paths. The switching process is fast and accurate, which facilitates the efficient realization of control response. This invention can drive the push rod to move via hydrodynamics, and the movement of the push rod drives the valve stem to rotate. After the water intake stops, the valve stem can be reset by the action of the return spring. The entire switching process does not require manual intervention, nor does it require external or internal power supply. It relies entirely on hydrodynamics to drive the valve stem to rotate, and automatically realizes the water circuit switching.

[0020] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. Attached Figure Description

[0023] Example 1 See Figures 1 to 9 A toilet flushing system includes a built-in power water source, an external power water source, and a flushing control device. The built-in power water source performs the first flushing process through a water tank and the flushing control device. After a period of time, the flushing control device switches, and the built-in power water source and the external power water source start flushing simultaneously. After the internal and external power water sources finish rinsing simultaneously, the external power water source continues rinsing until rinsing is complete; The flushing water path corresponding to the first flushing process is the flushing water path for the toilet seat wall area. When the two water paths flush simultaneously, the built-in power water source flushes the bottom area of ​​the toilet bowl, and the external power water source flushes the toilet seat wall area.

[0024] The flushing control device includes a flushing system combination valve, which has an inlet A1, an inlet B2, an outlet A3, and an outlet B4. The flushing system combination valve has a water supply chamber A5 and a water supply chamber B6. The inlet A1 is connected to the water supply chamber A5 through the water inlet passage A10, and the inlet B2 is connected to the water supply chamber B6 through the water inlet passage B20. The water supply chamber A5 is connected to the outlet B4 and a first valve 11 is provided at the connection point. The water supply chambers A5 and B6 are connected and a second valve 12 is provided at the connection point. The water supply chamber B6 is connected to the outlet A3 and a third valve 13 is provided at the connection point.

[0025] The inlet A1 is connected to the outlet channel of the water tank, and a water pump is installed on the outlet channel. The inlet B2 is connected to the inlet channel of the tap water pipe. The outlet A3 is connected to the flushing water channel of the ring wall area, and the outlet B4 is connected to the flushing water channel of the pool bottom area.

[0026] A rotating shaft 7 is rotatably installed in water supply chamber A5 and water supply chamber B6. A first valve 11, a second valve 12 and a third valve 13 are connected to the rotating shaft 7. When the rotating shaft 7 rotates to the first working angle, the second valve 12 and the third valve 13 are opened and the first valve 11 is closed. When the rotating shaft 7 rotates to the second working angle, the second valve 12 is closed and the first valve 11 and the third valve 13 are opened.

[0027] The first valve 11 and the third valve 13 are baffle-type structures. When rotated to a specific angle, the baffle can close the connection. The second valve is a flow-through hole type structure. When rotated to a specific angle, the flow-through hole opens the connection. The switching of different states is achieved by setting the staggered angles of the baffle and the flow-through hole.

[0028] The rotating shaft 7 is connected to a switching mechanism, which controls the rotating shaft 7 to rotate to a first working angle or a second working angle.

[0029] The switching mechanism is a float 8. The rotating shaft 7 is connected to the drive shaft 72 via a transmission gear set 71. A drive handle 73 is mounted on the drive shaft 72. A return spring 74 is connected to the drive handle 73. The drive handle 73 is connected to the float 8 via a linkage mechanism 75. When the float 8 descends to a certain position, it triggers the linkage mechanism 75, which drives the drive handle 73 to press down, thereby driving the rotating shaft 7 to rotate. After the float 8 rises again, the return spring 74 controls the drive handle 73 to return to its original position.

[0030] The transmission gear set 71 is a bevel gear set.

[0031] The water inlet channel A10 is equipped with a water inlet valve A21; the water inlet channel B20 is equipped with a water inlet valve B22.

[0032] In this embodiment, the flushing system combination valve is installed in the water tank. When the water pump is turned on to supply water for flushing, the water level in the water tank will continue to drop. When the float in the water tank drops to a certain level, the float will fall, thereby triggering the linkage mechanism, causing the linkage mechanism to press down. The output end of the linkage mechanism is located above the drive handle. The drive handle is provided with an inclined surface that contacts the output end of the linkage mechanism. After the linkage mechanism presses down, it will drive the drive handle to rotate downward, driving the drive shaft to rotate. The drive shaft drives the rotating shaft to rotate through the bevel gear set, rotating the rotating shaft from the first working angle to the second working angle.

[0033] When the entire flushing process is complete, the water tank begins to replenish water. When the water level in the tank returns to normal, the float returns to its original position, the drive handle returns to its original position under the action of the return spring, and the switching mechanism returns to its original position at the same time.

[0034] Example 2 See Figures 10 to 14 The switching mechanism is a motor, and the rest is the same as in Embodiment 1.

[0035] In this embodiment, the switching between different water inlet modes is achieved by driving the rotating shaft with a motor.

[0036] Example 3 See Figures 15 to 16 The switching mechanism includes a water inlet channel 91, a mounting base 92 in the water inlet channel 91, a push rod 93 movably mounted on the mounting base 92, a sealing element 94 for closing the water inlet channel 91 on the push rod 93, a compression spring 95 between the sealing element 94 and the mounting base 92, and a pressure rod 96 for switching the water path connected to the end of the push rod 93 away from the sealing element 94. When water enters the water inlet channel 91, the push rod 93 pushes the pressure rod 96 downward, thereby driving the drive handle 73 to press down, thereby driving the rotating shaft 7 to rotate, thereby switching the water path. After the water inlet stops, the push rod 93 returns to its original position under the action of the compression spring 95, and the drive handle 73 returns to its original position under the action of the return spring 74.

[0037] Everything else is the same as in Example 1.

[0038] The working process of this invention: When flushing begins, the shaft is at the first working angle, the inlet valve B is closed, the first valve closes the outlet B, the water pump is turned on, and the water pump delivers water from the tank to the inlet A, connecting the inlet A and the supply chamber A. The second valve is in the open position, connecting the supply chamber A and the supply chamber B. The third valve is in the open position, connecting the supply chamber B and the outlet A, so that the inlet water path A can discharge water through the outlet A, supplying water to the flushing water path of the ring wall area, and carrying out the first flushing work of the ring wall area. After a period of time, the system switches to the bottom flushing mode. The switching mechanism rotates the shaft to the second working angle, and the second valve rotates to the closed angle, closing the connection between water supply chamber A and water supply chamber B. The first valve is in the open position, opening the outlet B. Water from the inlet water path A flows out through the outlet B to flush the bottom area of ​​the pool. At the same time, the inlet valve B switches to the open state, while the third valve remains open. Water is supplied from the tap water pipe, and water from the inlet water path B flows out through the outlet A, simultaneously flushing the secondary ring wall area. After the bottom area is rinsed, the water pump stops supplying water, the inlet valve A closes, the inlet water circuit A stops supplying water, the inlet valve B remains open, and the tap water pipe continues to supply water to the flushing water circuit of the ring wall area to continue the secondary flushing of the ring wall area.

[0039] After the secondary ring wall area is flushed, the inlet valve B is closed, the tap water pipe is switched to replenish water to the water tank, and the tap water supply is stopped after the replenishment is completed.

[0040] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
