The switching unit body 55 is provided with a switching unit water inlet 551 connected with the valve water outlet 54, the water outlet cover 61 is provided with a basin rim port 611 communicated with a basin rim cover hole 6110, a pressure port 612 communicated with a pressure cover hole 6120 and a water replenishing port 613 communicated with a water replenishing cover hole 6130, and the water retaining cover 60 is driven by the motor 58 through 59 to cover any two of the basin rim cover hole 6110, the pressure cover hole 6120 and the water replenishing cover hole 6130 at any rotation angle so that water from the switching unit water inlet 551 flows out through an uncovered waterway port. The optimized switching unit body 55 can also be used as a support for a motor or a transmission control unit, as shown in fig. 4, a motor chamber 552 on the switching unit body 55 provides a chamber for placing the motor 58, a fixed shaft 553 provides a rotating shaft for 56, and a spring supporting plate 554 provides a support for the spring 57.

The transmission control unit comprises a shaft 59, a shifting fork assembly 62, a buoy trigger rod 56 and a spring 57, wherein the shifting fork assembly 62 comprises a drainage shifting fork 621, a rod driving part 622 and a rod resetting part 623, when the rotating motor 58 drives the shaft 59 to rotate, the water retaining cover 60 and the shifting fork assembly 62 rotate along with the shifting fork, in the process, the drainage shifting fork 621 drives the drainage valve 32 to open, the rod driving part 622 drives the buoy trigger rod 56 to enable the buoy 52 to move downwards so as to enable the valve 53 to open, and when the motor rotates backwards, any one of the rod resetting part 623 and the spring 57 can enable the buoy trigger rod 56 to reset.

The rim port 611 is communicated with the rim water inlet 10 through the rim pipeline 11, the pressure port 612 is communicated with the pressure water inlet 40 through the pressure water pipe 41, wherein the pressure water pipe 41 is provided with a connector 411 at the position of passing through the water tank 33, the water outlet of the drain valve 32 is communicated with the water inlet 30 of the water tank through the water pipe 31 of the water tank,

referring to fig. 7, the drain valve 32 has a valve cover 36, a draw cord 34 for driving the valve cover 36 to open, and a valve seat 35 for securing the drain valve 32 and providing a portion of the downstream waterway.

The movement state of the water inlet control module is described below with reference to fig. 7 to 11 for different states of the toilet.

In normal state, the device enters the state before operation.

In a normal state, as shown in fig. 7, the motor causes the drain fork 621 to be in a state shown in the drawing, the drain fork 621 causes the rope 34 to be in a loose state, and the valve cover 36 closes the drain valve 32 by gravity. The water blocking cover 60 is made by the motor 58 to shield the basin rim cover hole 6110 and the pressure cover hole 6120 to prevent water from flowing to the basin rim opening 611 and the pressure opening 612, and the valve water outlet 54, the switching unit water inlet 551, the water supplementing cover hole 6130 and the water supplementing opening 613 are conducted to form a thick water channel.

The float trigger lever 56 is in non-contact with the float 52 under the action of the spring 57. At this time, if the water level in the water tank 33 is low, the float 52 falls down, and then the valve 53 is turned on, and flows to the water tank through the valve outlet 54, the switching unit inlet 551, the water supplement cover hole 6130, and the water supplement port 613, and when the water level reaches a set height, the float 52 floats, and the valve 53 is closed. The toilet bowl is not filled with water.

At this time, if the water level in the tank 33 reaches a predetermined level, the float 52 floats up to close the valve 53, and the toilet bowl is kept in a state of no water intake.

The following will describe the state of the toilet in operation in steps.

In a first step, the rim water inlet 10 is fed for washing the bowl, as will be explained with reference to fig. 8.

Based on the normal state, the motor 58 drives the shaft 59 to rotate, and drives the water blocking cover 60 and the shifting fork assembly 62. The water blocking cover 60 rotates to gradually shield the pressure cover hole 6120 and the water replenishing cover hole 6130, so that water is prevented from flowing to the pressure port 612 and the water replenishing port 613, and the valve water outlet 54, the switching unit water inlet 551 and the basin edge port 611 are communicated to form a thick water channel. The drain fork 621 on the fork assembly 62 rotates about 120 degrees, and in this process, the pull rope 34 is in a loose state, and the drain valve is closed under the action of gravity. The cam structure of the lever drive 622 drives the float trigger lever 56 against the spring force of the spring 57, pressing the float 52 downwards, causing the valve 53 to open for filling the toilet bowl. Most of the water flows to the water inlet 10 at the edge of the closestool through the pressure port 612 and the pipeline 11 at the edge of the closestool, so that the bowl part of the closestool is cleaned. The basin part is kept for a certain time to be fully cleaned.

And secondly, the water inlet 10 at the edge of the basin is fed, and the water inlet 30 of the water tank and the pressure water inlet 40 are fed, so that accumulated water and dirt can be discharged, and the method is explained with reference to fig. 9.

After the first step is maintained for a period of time, the two water inlets of the water storage part are filled with water so as to discharge the stored water in the toilet.

At this time, the motor 58 drives the shaft 59 to rotate, and drives the water blocking cover 60 and the shifting fork assembly 62.

The cam structure of the lever drive 622 still drives the float trigger lever 56 against the spring force of the spring 57, pressing the float 52 downwards, causing the valve 53 to open for filling the toilet bowl. The water blocking cover 60 rotates to gradually shield the basin rim cover hole 6110 and the water supplementing cover hole 6130, so as to prevent water from flowing to the basin rim opening 611 and the water supplementing opening 613, and the valve water outlet 54, the switching unit water inlet 551 and the pressure opening 612 are communicated to form a thick waterway channel, so that most of water is discharged to the bottom of the toilet through the pressure water pipe 41 and the water tank water inlet 30. Meanwhile, the water discharge shifting fork 621 on the shifting fork assembly 62 rotates about 120 degrees, and in the process, the pulling rope 34 is in a tensioning state, so that the water discharge valve is pulled open, and the stored water in the water tank is discharged to the bottom of the toilet bowl through the water discharge valve 32, the water tank water pipe 31 and the water tank water inlet 30.

During this time tank 33 level drops and float 52 naturally falls, also causing valve 53 to remain open. The water discharged from the water inlet 30 of the water tank and having the gravitational potential energy converted into the supporting hydraulic energy and the water discharged from the pressure water inlet 40 and directly injecting the pressure energy of the water source into the toilet are mixed and instantly discharged to the toilet together, so that strong drainage force is generated to discharge the dirt in the toilet.

In this step, the relation between the drain fork 621 and the water blocking cover 60 may be set to have a certain time difference when water is supplied to the tank water inlet 30 and the pressure water inlet 40, which is only a simple change of the physical installation angle and will not be described herein.

In this step, the currently used drain valve with a drain control float can be used to replace the drain valve 32 of this example, and the stepping motor 58 is arranged to only pull up the pull rope 34 instantaneously, and then the float of the drain valve controls the size of the drain, which is also a simple change of this example and is not described herein.

And a third step of finishing the water supply to the pressure water inlet 40 and starting the water supply to the basin rim water inlet 10 so that the water level of the water storage part returns to the initial state to isolate the odor of the building pipeline, which is described with reference to fig. 8.

At this time, the motor 58 drives the shaft 59 to rotate reversely by about 120 degrees, and drives the water blocking cover 60 and the shifting fork assembly 62.

Because the water level in the water tank 33 is low, the float 52 loses buoyancy and naturally falls, the valve 53 is continuously opened, the cam of the rod driving portion 622 can drive or not drive the float trigger rod 56, in this example, the cam still drives the float trigger rod 56, and unsmooth movement of the float 52 under gravity is avoided. The water blocking cover 60 rotates reversely to gradually shield the pressure cover hole 6120 and the water replenishing cover hole 6130, so that water is prevented from flowing to the pressure port 612 and the water replenishing port 613, the valve water outlet 54, the switching unit water inlet 551 and the bowl edge port 611 are communicated, and similarly to the first stage, water is filled into the toilet bowl from the bowl edge. Meanwhile, the drain fork 621 of the fork assembly 62 rotates about 120 degrees along with the shaft 59 in the opposite direction, in the process, the tension or the slack of the pull rope 34 is changed into the slack, and the valve cover 36 falls along with the gravity to close the valve of the water inlet module.

After maintaining the above state for a while, the water in the water accumulating part is gradually restored to the initial state.

Fourthly, the water supply to the rim water inlet 10 is finished, and the water tank is replenished with water so that the toilet returns to a normal state, which will be described with reference to fig. 10.

Based on the third step, the motor 58 drives the shaft 59 to rotate in the reverse direction by about 120 degrees, and drives the water blocking cover 60 and the shifting fork assembly 62. Meanwhile, the water discharge shifting fork 621 on the shifting fork assembly 62 rotates reversely along with the shaft 59, in the process, the pull rope 34 still keeps loose, and the water discharge valve is closed.

Because the water level in the water tank 33 is low, the float 52 loses buoyancy and naturally falls, the valve 53 is continuously opened, and at this time, in order to avoid the influence of the float trigger lever 56 on the floating of the float 52, the float trigger lever 56 is forcibly reset through the lever reset portion 623 on the shifting fork assembly 62.

The water blocking cover 60 rotates reversely with the motor 58 to gradually shield the basin rim cover hole 6110 and the pressure cover hole 6120, similarly to the initial state, the water is prevented from flowing to the basin rim port 611 and the pressure port 612, the valve outlet 54, the switching unit water inlet 551 and the water replenishing port 613 are conducted, a large amount of water enters the water tank 33 until the water level reaches a set value, and then the float bowl 52 closes the float valve 53. The toilet returns to the initial state.

The present application has been described above in a brief summary with reference to specific embodiments, but the present application is not limited to these specific embodiments. That is, as long as the features of the present invention are provided, the technique of appropriately changing these embodiments by those skilled in the art is also included in the scope of the present invention, and the elements, the arrangement, materials, conditions, shapes, sizes, and the like thereof are appropriately changed, for example: 1. the embodiment of the present invention in which the drain fork 621 directly drives the drain valve 32 is modified to open the drain valve 32 by using the flowing pressure or speed of the water flowing from the pressure port 612 to the pressure water inlet 40, and the specific scheme for opening the drain valve 32 is described in the chinese patent application No. 202120050481.2, and is omitted here. And 2, a valve for feeding water into the water tank is independently arranged, and the function of feeding water into the water tank by the switching unit is cancelled. Using additional electromagnetic means to drive the valve body to open the water supply to the toilet bowl rim water inlet 10 and the pressurized water inlet 40. The above schemes or the superposition of the schemes are all within the protection scope of the application.

For the toilet, all actions are controlled by the motor 58, and the state of the motor 58 can be controlled by a main control program and a circuit, so that the time duration of each step is distributed, and the control of large flushing/small flushing is realized. The scheme has simple structure and low cost. However, under the condition of occasional power failure, a container such as a washbasin is needed for assisting in flushing the toilet, so that the toilet is inconvenient to use, the optimization is further carried out, and a power failure flushing assembly is added to solve the problem.

As will be described below with reference to fig. 11 to 13, the water path is added with: a one-way valve 633 is arranged in the basin rim port 611 to prevent water from flowing back to a water replenishing cover hole 6130, a pressure spring 6131 and a blocking cover 6132 are connected at the outlet of the water replenishing port 613, a connecting pipe 631 is led out from a pipeline between the one-way valve 633 and the basin rim water inlet 10, the other end of the connecting pipe 631 is connected with a pipeline between the water replenishing cover hole 6130 and the blocking cover 6132, and a one-way valve 632 is placed in the connecting pipe 631 to prevent water from flowing from the basin rim port 611 to the blocking cover 6132.

The driving parts are added: the additional rotating lever 7 includes a float-pressing cylinder portion 71, a water replenishment port suppressing portion 72, and a drain valve driving portion 73, and the rotating lever 7 is fixed to the switching unit main body 55 by a tension of the pull cord 70 so as to be rotatable. The float 52 is driven to descend when the float cylinder part 71 moves downward, and the float 52 is not influenced by the float cylinder part 71 when the float cylinder part 71 moves upward. The water replenishing port inhibiting portion 72 can drive the blocking cover 6132 to close the water replenishing port 613 when moving upwards, and the pressure spring 6131 extends to push the blocking cover 6132 open to open the water replenishing port 613 when the water replenishing port inhibiting portion 72 moves downwards. Actuation of the pull cord 34 to move the valve cover 36 to open the valve 32 when the drain valve actuator 73 moves upward.

When the toilet is in a flushing state, a power failure occurs, a large capacitor can be added to the circuit, so that the motor returns to a normal water path, namely, the valve water outlet 54 is communicated with the water replenishing port 613. If power is off in the normal state, the above-mentioned worry is not generated.

At this time, the pull cord 70 is pulled up to rotate the rotary lever 7 around the rotary shaft of the switching unit body 55, and the float cylinder 71 moves down to press the float 52 to open the valve 53, so that the water source starts to supply water to the toilet. At the same time, the water replenishing port inhibiting portion 72 moves upward to close the water replenishing port 613, and water flows to the toilet through the water replenishing cover hole 6130, the connecting pipe 631, the rim port 611, the rim pipe 11, and the rim water inlet 10. At the same time, the drain valve driving part 73 moves upwards to touch the pull rope 34 to make the valve cover 36 move to open the drain valve 32, and a large amount of water in the water tank instantly flows into the water accumulation part of the toilet through the water storage part 30 to generate certain thrust so as to discharge accumulated water and dirt in the water accumulation part. The pulling rope 70 is kept in the pulling state all the time, and because the water in the water tank flows, the water flowing in from the basin edge water inlet 10 starts to be accumulated water in the water accumulation part 24 until the accumulated water reaches a certain height.

Then the pull rope 70 is loosened, the rotating rod 7 is reset under the action of the pressure spring 6131, the water replenishing port 613 is opened, water flows to the water tank from the water replenishing port 613 because the one-way valve 632 has certain resistance, and the float 52 floats to cause the valve 53 to be closed until the water level of the water tank reaches a preset value.

In this post-blackout flush scenario, the user can achieve the following 3 processes in sequence with only one action: the water inlets 10 and 30 on the basin edge simultaneously feed water into the toilet, and the water inlet 10 on the basin edge accumulates water in the water accumulating part of the toilet and replenishes water into the water tank.

Certainly this scheme is compared and is given ponding portion water in the twinkling of an eye less when using the motor, and the blowdown ability correspondence can descend, nevertheless under this kind of accidental circumstances, also can carry out interim use, has avoided looking for the trouble of basin water receiving.
