in this embodiment, the pressure water channel 11 is communicated with the water diversion cavity 36 through the cover 35, and the first water channel 211 and the second water channel 212 of the water outlet pipe 21 are communicated with the water diversion cavity 36 through two water outlets formed in the body 34; one surface of the switching piece 31 facing the two water outlets forms surface sealing with the body 34; when the switch 31 is rotated, the pressure waterway 11 is communicated with the first waterway 211 through the first through hole 311, the second waterway 212 through the second through hole 312, and the first waterway 211 through the third through hole 313 in this order.

Referring to fig. 3 to 11, the toilet waterway switching system of the present embodiment is implemented by the following control method: in an initial state, the toilet tank 321 is at a highest water level, i.e., a first water level, the float assembly 322 floats upwards along the float guide rail 40 to a highest position, i.e., a first position, under the action of water buoyancy, and at this time, the switching member 31 communicates the pressure water channel 11 with the first water channel 211 through the first through hole 311 and blocks the pressure water channel 11 from the second water channel 212;

step 1: the water suction pump 12 receives a first operation instruction, pumps water from the water tank 321 to the pressure water channel 11, and the water in the pressure water channel 11 flows to the first water channel 211 through the water diversion cavity 36 and the first through hole 311;

step 2: when the water pump 12 is operated, the water level of the water tank 321 changes from the first water level to the second water level; step 2 is carried out simultaneously with step 1; at this time, because the water pressure of the pressure water channel 11 is increased under the action of the water pump 12, pressure is formed on the switching piece 31 in the water dividing cavity 36, and the switching piece 31 overcomes the gravity of the float assembly 322 under the action of surface contact friction force with the body 34, so that the switching piece 31 is blocked from rotating, the float assembly 322 linked with the switching piece 31 cannot fall down along with the water level of the water tank 321 in real time, and the pressure water channel 11 is ensured to be communicated with the first water channel 211 through the first through hole 311 of the switching piece 31 all the time when the water pump 12 operates for the first time;

And step 3: the method comprises the following steps:

substep 3.1: after the water pump 12 operates for the first period set artificially, the water pump 12 stops operating for the second period set artificially, the pressure water channel 11 is cut off to supply water to the first water channel 211, and at the moment, the water level of the water tank 321 drops to the second water level;

Substep 3.2: as the water pressure of the pressure water channel 11 is reduced, the pressure applied to the switching member 31 is eliminated, the float assembly 322 falls to the second position under the action of gravity, and the swing rod is linked with the switching member 31 to rotate by a first preset angle, so that the switching member 31 is communicated with the pressure water channel 11 and the second water channel 212 through the second through hole 312, and the pressure water channel 11 and the first water channel 211 are blocked;

And 4, step 4: after the water suction pump 12 stops operating for a second period set manually, the water suction pump is started again to operate for the second time, water is sucked from the water tank 321 to the pressure water channel 11, and water in the pressure water channel 11 flows to the second water channel 212 through the water diversion cavity 36 and the second through hole 312;

and 5: when the water pump 12 operates, the water level of the water tank 321 decreases, the water pressure of the pressure water channel 11 increases under the action of the water pump 12, pressure is formed on the switching piece 31, and the switching piece 31 overcomes the gravity of the float assembly 322 under the action of surface contact friction force with the body 34, so that the rotation of the switching piece 31 is blocked, and the pressure water channel 11 is ensured to be communicated with the second water channel 212 through the second through hole 312 of the switching piece 31 all the time when the water pump 12 operates for the second time;

step 6: the method comprises the following steps:

Substep 6.1: after the water pump 12 operates for the artificially set third period, the water pump 12 stops operating for the artificially set fourth period, the pressure water channel 11 is cut off to supply water to the second water channel 212, and at this time, the water level of the water tank 321 drops to the third water level;

Substep 6.2: as the water pressure of the pressure water channel 11 is reduced, the pressure applied to the switching member 31 is eliminated, the float assembly 322 falls to the third position under the action of gravity, and continues to rotate by the second preset angle through the swing rod linked switching member 31, so that the switching member 31 communicates the pressure water channel 11 with the first water channel 211 through the third through hole 313, and blocks the pressure water channel 11 from the second water channel 212;

and 7: after the water suction pump 12 stops operating for the artificially set fourth period, the water suction pump is started again to operate for the third time, water is sucked from the water tank 321 to the pressure water channel 11, and water in the pressure water channel 11 flows to the first water channel 211 through the water diversion cavity 36 and the third through hole 313; the water level of the water tank 321 is lowered, and similarly, under the action of the water pump 12, the water pressure of the pressure water channel 11 is increased to form pressure on the switching piece 31, and the switching piece 31 overcomes the gravity of the float assembly 322 under the action of surface contact friction force with the body 34, so that the rotation of the switching piece 31 is blocked, and the pressure water channel 11 is always communicated with the first water channel 211 through the third through hole 313 of the switching piece 31 when the water pump 12 operates for the third time.

and 8: after the water pump 12 operates for the artificially set fifth period, the water pump 12 stops operating, at this time, the water level of the water tank 321 drops to the fourth water level, i.e., the lowest water level, and the buoy assembly 322 drops to the fourth position, i.e., the lowest position; the water injection device starts to add water into the water tank 321 from an external water source, so that the water level of the water tank 321 is gradually increased from the lowest water level, the float assembly 322 floats upwards under the action of water buoyancy and is synchronously linked with the swing rod to drive the switching piece 31 to rotate until the water level of the water tank 321 reaches the first water level, the float assembly 322 rises to the highest position, and the switching piece 31 is driven by the swing rod to return to the initial state.

In other embodiments, the water outlet pipe 21 can be set to more than two water paths according to the number of the flushing ports of the toilet bowl, so as to adapt to the requirements of multifunctional flushing water paths; correspondingly, the switching member 31 may be provided with more through holes to realize that the toilet is flushed by multiple water paths according to a predetermined sequence.

in other embodiments, the switch 31 may be provided with only the first through hole 311 and the second through hole 312, and during the falling of the float assembly 322, the switch 31 is linked to rotate, so that the pressure channel 11 is communicated with the first waterway 211 through the first through hole 311 and communicated with the second waterway 212 through the second through hole 312 sequentially, that is, the pressure channel 11 is no longer communicated with the first waterway 211 secondarily.

The control method of the present embodiment further includes controlling the positioning assembly.

In this embodiment, the positioning assembly 37 includes a limiting rod 371 and a piston channel 372, wherein the piston channel 372 is formed on the cover 35 and is connected to the pressure channel 11; one end of the limiting rod 371 is inserted into the piston channel 372 and is in sealing sliding fit with the piston channel 372 so as to slide outwards under the action of water pressure in the piston channel 372; the other end of the limiting rod 371 extends into the limiting sliding groove 373 and can freely slide in the limiting sliding groove 373; when the limiting rod 371 extends out of the limiting sliding groove 373, the limiting rod 371 can limit the position of the movable rod 324 of the float assembly 322, and when the limiting rod 371 retracts into the limiting sliding groove 373, the limiting rod 371 and the movable rod 324 yield.

the float 323 is provided with an abutting portion 323a and a guide hole 323 b. The float 323 is slidably connected to the vertically arranged float guide rail 40 through the guide hole 323b, so that the float 323 can move up and down in the vertical direction along with the change of the water level of the water tank 321; the abutting part 323a restricts the reverse rotation of the movable rod 324 in the falling process, so that the movable rod 324 abuts against the limiting rod 371 at the limiting position, and the buoy assembly 322 is prevented from continuously falling; and when the flotation pontoon 323 floats in-process, even the gag lever post 371 is in the limiting position, because the movable rod 324 can freely forward rotate, the movable rod 324 can forward rotate and the separation of butt portion 323a, walk around the gag lever post 371, make flotation pontoon subassembly 322 continue the come-up, guarantee that the movable rod 324 and gag lever post 371 give way mutually. By taking the rotation axis of the movable rod 324 relative to the float 323 as a center, a counterweight block is arranged on one side of the movable rod 324 close to the abutting part 323a, so that after the movable rod 324 bypasses the limiting rod 371, the movable rod 324 is driven to reversely rotate to abut against the abutting part 323 a; the floating cylinder 323 is rotatably connected to the movable rod 324, the structure is simple, the floating cylinder assembly 322 can reliably ensure limiting or yielding in the floating or falling process, and the stability of the operation of the switching module is ensured. In this embodiment, the weight block and the movable rod 324 are integrally formed.

in this embodiment, in the initial state, the limiting rod 371 is in a state of extending out of the limiting sliding groove 373; applying water pressure to the limiting rod 371 through the piston channel 372, so that the limiting rod 371 retracts to the limiting sliding groove 373; when the water pressure applied to the stop lever 371 is removed, the stop lever 371 is restored to the initial state under the effect of the resilience force of the elastic member.

in this embodiment, the limiting sliding groove 373 is integrally formed with the cover 35.

referring to fig. 15 to 17 and fig. 3 to 11, the toilet waterway switching system of the present embodiment is implemented by the following control method: in an initial state, the toilet tank 321 is at a highest water level, i.e., a first water level, the float assembly 322 floats upwards along the float guide rail 40 to a highest position, i.e., a first position, under the action of water buoyancy, and at this time, the switching member 31 communicates the pressure water channel 11 with the first water channel 211 through the first through hole 311 and blocks the pressure water channel 11 from the second water channel 212; the limiting rod 371 is at a limiting position;

Step 1: the water suction pump 12 receives a first operation instruction, pumps water from the water tank 321 to the pressure water channel 11, and the water in the pressure water channel 11 flows to the first water channel 211 through the water diversion cavity 36 and the first through hole 311; meanwhile, the pressure water in the pressure water channel 11 is distributed to the piston channel 372, and the pressure water applies water pressure to the limiting rod 371 from the inside of the piston channel 372, so that the limiting rod 371 in the piston channel 372 slides outwards to drive the limiting rod 371 in the limiting chute 373 to retract, and the limiting rod 371 gives way to the movable rod 324;

step 2: step 2 in the same embodiment one is not described again;

And step 3: the method comprises the following steps:

Substep 3.2: along with the reduction of the water pressure of the pressure water channel 11, the pressure applied to the switching piece 31 is eliminated, meanwhile, the pressure applied to the limiting rod 371 in the piston channel 372 is also eliminated, and the limiting rod 371 is restored to the limiting position in limiting fit with the movable rod 324 under the action of the resilience force of the elastic piece; the float assembly 322 falls under the action of gravity, and because the movable rod 324 cannot continue to rotate reversely under the action of the abutting part 323a, the movable rod 324 and the limiting rod 371 are limited, the float assembly 322 can only fall to the limiting position where the movable rod 324 and the limiting rod 371 are in limited fit, so that the falling stroke of the float assembly 322 is ensured, the swing rod linkage switching piece 31 can be accurately controlled to rotate to enable the second through hole 312 to communicate the pressure water channel 11 and the second water channel 212, and the pressure water channel 11 and the first water channel 211 are blocked;

And 4, step 4: after the water suction pump 12 stops operating for a second period set manually, the water suction pump is started again to operate for the second time, water is sucked from the water tank 321 to the pressure water channel 11, and water in the pressure water channel 11 flows to the second water channel 212 through the water diversion cavity 36 and the second through hole 312; meanwhile, the pressure water in the pressure water channel 11 is distributed to the piston channel 372, and the pressure water applies water pressure to the limiting rod 371 from the inside of the piston channel 372, so that the limiting rod 371 in the piston channel 372 slides outwards to drive the limiting rod 371 in the limiting chute 373 to retract, and the limiting rod 371 gives way to the movable rod 324;

And 5: step 5 in the same embodiment one is not described again;

Step 6: the method comprises the following steps:

Substep 6.2: as the water pressure of the pressure water channel 11 is reduced, the pressure applied to the switching piece 31 is eliminated, and the buoy assembly 322 continues to fall to the third position under the action of gravity, and the movable rod 324 is located below the limiting position; the buoy assembly 322 falls to drive the swing rod to link the switching piece 31 to continue to rotate by a second preset angle, so that the switching piece 31 is communicated with the pressure water channel 11 and the first water channel 211 through the third through hole 313 and blocks the pressure water channel 11 and the second water channel 212;

and 7: after the water suction pump 12 stops operating for the artificially set fourth period, the water suction pump is started again to operate for the third time, water is sucked from the water tank 321 to the pressure water channel 11, and water in the pressure water channel 11 flows to the first water channel 211 through the water diversion cavity 36 and the third through hole 313; the water level of the water tank 321 is lowered, and similarly, under the action of the water pump 12, the water pressure of the pressure water channel 11 is increased to form pressure on the switching piece 31, and the switching piece 31 overcomes the gravity of the float assembly 322 under the action of surface contact friction force with the body 34, so that the rotation of the switching piece 31 is blocked, and the pressure water channel 11 is always communicated with the first water channel 211 through the third through hole 313 of the switching piece 31 when the water pump 12 operates for the third time. At this stage, since the movable rod 324 is already located below the limit position, the limit rod 371 no longer limits the movable rod 324;

And 8: after the water pump 12 operates for the artificially set fifth period, the water pump 12 stops operating, at this time, the water level of the water tank 321 drops to the lowest water level, i.e., the fourth water level, and the buoy assembly 322 is located at the lowest position, i.e., the fourth position; the water injection device starts to add water into the water tank 321, so that the water level of the water tank 321 gradually rises from the lowest water level, and the buoy assembly 322 moves upwards along the buoy guide rail 40 from the most four positions under the action of water buoyancy and drives the movable rod 324 to move upwards; in the upward movement process, the movable rod 324 is separated from the abutting part 323a under the action of the limiting rod 371, rotates in the forward direction, bypasses the limiting rod 371, and returns to a position capable of being in limited fit with the limiting rod 371 under the action of the balancing weight; in the floating process of the buoy assembly 322, the swing rod is synchronously linked to drive the switching piece 31 to rotate until the water level of the water tank 321 reaches the highest water level, the buoy assembly 322 rises to the highest position, and the switching piece 31 is driven by the swing rod to return to the initial state.

In other embodiments, a plurality of limiting rods 371 which are sequentially and limitedly matched with the movable rod 324 can be arranged, the limiting rods 371 are arranged in parallel in the same vertical direction, the float assembly 322 is limited at a preset position by the limiting rods 371 from top to bottom in a falling process, so that the rotating angle of the switching piece 31 linked with the float assembly 322 can be accurately controlled at each time, the accuracy of the switching module for controlling the switching piece 31 to communicate with each water channel is further improved, and the influence of the fluctuation of the water level of the float assembly 322 by the water tank 321 on the rotating angle of the switching piece 31 is avoided.

In other embodiments, the movable rod 324 can be reset to a position capable of being in limit fit with the limiting rod 371 under the action of elastic reset force.
